Background

Two-wheeled vehicles, such as two-wheeled electric vehicles, two-wheeled motorcycles, and the like. Compared with three-wheel and four-wheel vehicles, the two-wheel vehicle has the advantages of light weight, convenience, cheapness and low requirements on drivers, and is therefore a preferred vehicle for many people. To improve the comfort of the driver, the driver's seat of a two-wheeled vehicle is usually provided to be wide and long, and this design form enables more than two persons to actually sit on the seat.

However, lightweight small two-wheeled vehicles are typically designed to carry only one person (i.e., the driver), and are typically not overloaded by more than one child under 12 years old, and are overloaded by more than two children or by more than one adult. "overload" herein means: after people carry, the weight of the whole vehicle exceeds the design standard, so that the gravity center of the whole vehicle is unstable, and the braking and steering are easy to run away. On the other hand, after the storage battery, the oil tank and the gas tank are removed, the weight of the frame of the portable small-sized two-wheeled vehicle is only about 35 kg, the load capacity is limited, and if the frame is overloaded, the overload of the frame is caused, so that potential safety hazards are formed.

All other embodiments, based on the embodiments of the application, which would be apparent to one of ordinary skill in the art without undue burden are intended to be within the scope of the present application.

The present description provides a two-wheeled vehicle, which may be a two-wheeled electric vehicle, a two-wheeled motorcycle.

Two-wheeled vehicles that can carry people are generally classified into two cases according to the form of a seat cushion, the first case being that a driver seat cushion is long and wide enough to carry many people, in which case a rear seat is not usually provided alone, and the second case being that a rear seat is provided alone behind a driver seat, in which case the driver seat is generally small and cannot sit on two people at all. The present description provides a solution for overload only for the first case, wherein overload refers to the loading of more than two children beyond a predetermined age or weight in addition to the driver; or may carry an adult in addition to the driver.

Fig. 1 shows a schematic structural diagram of a two-wheeled electric vehicle, as shown in fig. 1, the two-wheeled electric vehicle is provided with a seat cushion 1, electricity Chi Cang is arranged below the seat cushion 1, and a plurality of batteries are stored in a battery compartment to form a battery pack so as to provide a power source for the two-wheeled electric vehicle. The two-wheeled electric vehicle includes a front wheel 31 and a rear wheel 32, wherein the rear wheel 32 is a driving wheel, and the front wheel 31 is a driven wheel. A drive motor 4 is provided at the shaft portion of the rear wheel 32, and the drive motor 4 is connected to the output end of the battery pack in the battery compartment 2. A motor controller 5 is arranged below the pedal of the two-wheeled electric vehicle, and the output end of the motor controller 5 is connected with the control end of the driving motor 4 and is used for controlling the rotation of the driving motor 4 and controlling the rotation speed. The handlebar 6 of the two-wheeled electric vehicle is provided with an accelerating assembly and a braking assembly, a dashboard 7 is arranged at the position of the vehicle head between the left and right handlebars and used for displaying the vehicle speed, prompting information, alarming information and the like, the vehicle head is also provided with a sound prompting device such as a loudspeaker 8 and the like, the accelerating assembly, the braking assembly, the dashboard 7, the loudspeaker 8 and the like are all connected with a central controller 9, and the central controller 9 can be arranged at the position on the vehicle head, which is close to the pedal. The connection relationship between the above-described various devices of the two-wheeled electric vehicle may be as shown in fig. 2.

The two-wheeled vehicle provided by the specification comprises a driving device, a cushion and at least two sensors and a controller which are arranged below the cushion. The drive device is used to drive the two-wheeled vehicle, for example, the drive motor 4 in fig. 1. The sensors disposed below the seat cushion are used to sense the pressure experienced by different portions of the seat cushion, such as sensors 101, 102 and 103 shown in fig. 1. The controller is connected with the output end of each sensor and is used for determining the number of passengers according to the output signals of each sensor, and when the number of passengers does not meet the preset condition, the driving device is controlled to be in a locking state, namely the driving device does not work. For example, the controller may refer to a central controller 9 as shown in fig. 1.

The predetermined condition may be that the number of passengers is 1 adult, or one adult and one child, and the case where the predetermined condition is not satisfied includes at least one of: no one (e.g., where the driver is not sitting on the seat cushion to control the acceleration of the vehicle), two adults, one adult, and more than two children.

In some embodiments, the two-wheeled vehicle further comprises a prompting device for sending a prompting message to the user, wherein the prompting message is used for indicating that the passengers do not meet the preset condition. The controller is also used for controlling the prompting device to send out prompting information when the number of passengers does not meet the preset condition. The prompt information may include the number of detected passengers, for example, the prompt information may be voice information, and the content may be "two passengers are passengers, overloaded", "two adults are detected to be passengers", or the like. The prompting device can be an indicator lamp, a loudspeaker and the like.

The above sensor is not limited to a specific sensor product, but should be understood as a detection device capable of sensing measured information and converting the sensed information into an electrical signal or other desired form of information output according to a certain rule.

In some embodiments, the sensor may be a pressure sensor for detecting the pressure experienced by the seat cushion above the sensor. As shown in fig. 3A, these pressure sensors may be disposed at predetermined distances apart on the symmetry axis of the seat cushion. In particular, the predetermined distance may be any value between 65-75mm, for example, 70mm, and then the distance between sensors 101 and 102 may be 72mm and the distance between sensors 102 and 103 may be 75mm. Of course, the number of the sensors distributed at intervals on the symmetry axis of the cushion can be four or more, and the distance between the adjacent sensors can be other distance values, which is not listed in the application.

The controller determines the number of passengers according to the output signals of the sensors, and comprises the following steps: and according to the positions of the sensors on the symmetrical axes of the seat cushion, the output values of the sensors are corresponding to the symmetrical axes of the seat cushion, the number of the maximum values in the output values of the sensors on the symmetrical axes of the seat cushion is determined, and the number of the maximum values with the values larger than a preset threshold value is used as the number of passengers. In determining the maximum value, it is assumed that one virtual sensor is further provided on the outer sides of the two sensors at the upper edge of the seat cushion symmetry axis, respectively, and the pressure values output by the two virtual sensors are 0, that is, it is assumed that the pressure values on the outer sides of the two sensors at the upper edge of the seat cushion symmetry axis are 0, so that the output values of the edge sensors can be determined as the maximum value in some cases. Wherein the predetermined threshold value is used for distinguishing whether an adult or a child sits on the cushion part corresponding to the maximum value point.

In the present specification, a maximum point refers to a point on a straight line or a curved surface, where a value at a certain point is greater than a value at any point around the point and closest to the point in each direction, and the point is the maximum point. That is, on a straight line, a point is a maximum point if the value at the point is greater than the value at the closest point on both sides of the point.

For example, if the output values of the sensors 101, 102, 103 shown in fig. 3A are 100N (where N is a unit of force: newton), 400N, 150N, and 0N, 100N, 400N, 150N, 0N after the pressure value outside the edge sensor is supplied, the output value of the sensor 102 is the maximum value, and only this one maximum value is used, it is possible to determine that the number of passengers is 1; if the output values of the sensors 101, 102, 103 are 450N, 150N, 400N, and 0N, 450N, 150N, 400N, 0N after the pressure value outside the edge sensor is supplied, the output values of the sensors 101, 103 are maximum values, and 2 maximum values are available, so that the number of passengers can be determined to be 2; if the output values of the sensors 101, 102, 103 are 150N, 100N, 450N, and 0N, 150N, 100N, 450N, 0N after the pressure values outside the edge sensors are added, the output values of the sensors 101, 103 are maximized, but the output value of the sensor 101 is too small, and a child may sit on the corresponding position, so that the number of passengers can be determined to be 2, particularly an adult and a child, without overload.

In some embodiments, the pressure sensors may also be distributed in a curved surface. The plane is a special curved surface, so that, taking the case of a plane as an example, a planar plate body is arranged below the seat cushion, and a plurality of pressure sensors are arranged on the plate body, for example, the plurality of pressure sensors can be distributed symmetrically along the symmetry axis as shown in fig. 3B, and one dot in the figure represents one sensor. Accordingly, the controller determines the number of passengers based on the output signals of the plurality of sensors, including: and according to the positions of the sensors on the plane plate body, corresponding the output values of the sensors to the plane plate body, determining the number of maximum values in the output values of the sensors on the plane plate body, determining the number of maximum values on one side of a symmetrical axis of the cushion, and taking the number of maximum values with the value larger than a preset threshold value as the number of passengers. The preset threshold value is used for distinguishing whether an adult or a child sits on the cushion position corresponding to the maximum value point.

Because the pressure sensors are distributed in a curved surface, a mode of determining extreme points on the curved surface is adopted when determining the maximum value. It should be noted that, when determining the maximum value, it is assumed that the pressure value outside each sensor at the upper edge position of the curved surface formed by the sensor is 0.

In some embodiments, the outputs of the plurality of sensors may be directly connected to the input of a controller (i.e., the central controller in fig. 1), with the output signals of the plurality of sensors being directly processed by the controller. In some embodiments, a signal collector, such as the signal collector 11 shown in fig. 1, may be further provided, where the output ends of the plurality of sensors are connected to the input end of the signal collector 11, and the output end of the signal collector 11 is connected to the input end of the controller, that is, the output signals of the plurality of sensors are preprocessed by the signal collector, and then the preprocessed signals are sent to the controller, so as to reduce the data processing capacity of the controller.

In some embodiments, the sensor may be a first sensor that outputs a switching signal.

For example, the first sensor may have a structure as shown in fig. 4A and 4B, that is, the first sensor includes a base plate 41, a key 42, and an elastic member 43. The base plate 41 is provided with a first conductor 411 and a second conductor 412, the first conductor 411 and the second conductor 412 are disconnected, the first conductor 411 is connected with a power supply terminal, and the second conductor 412 serves as an output terminal of the first sensor.

The third conductive body 421 is disposed on a side of the key 42 facing the bottom plate 41, and other portions of the key 42 may be made of non-conductive materials. When the pressure carried by the cushion portion above the key 42 reaches a predetermined pressure value, the key 42 is pressed so that the third conductor 421 contacts the first conductor 411 and the second conductor 412 and forms a current path.

An elastic member 43 is provided on the base plate 41 for bouncing the key 42. For example, the elastic member 43 may be a spring piece disposed on the base plate 41 and located between the first conductor 411 and the second conductor 412; alternatively, the elastic member 43 may be a spring having one end fixed to the base plate 41 and the other end fixed to the key 42. Of course, other variant embodiments may be used, and this description is not intended to be limiting.

The power source terminal may be a high-level power source of +5v, or a low-level power source of-5V or 0V (i.e., ground), and may be set according to circumstances. It can be seen that the sensor shown in fig. 4A and 4B is capable of outputting a digital signal.

The predetermined pressure value may be determined based on a minimum pressure value applied to the seat cushion by an adult, and then the sensor outputs a first signal (for example, a low level signal) when the child sits on the seat cushion portion above the sensor, and outputs a second signal (for example, a high level signal) different from the first signal when the adult sits on the seat cushion portion above the sensor, so that it is possible to determine whether the child or the adult sits on the seat cushion based on the different signals outputted from the sensor.

The sensors shown in fig. 4A or 4B described above may be provided in two or three or more, and these sensors are spaced apart at least a predetermined distance on the symmetry axis of the seat cushion. Specifically, the predetermined distance may be any value between 65-75mm, for example 65mm, 70mm, 75mm.

For another example, the first sensor may have a structure as shown in fig. 5, that is, the first sensor includes a base plate 51, a key 52, and an elastic member 53. The bottom plate 51 is provided with a Hall sensor 511, and one side of the key 52 facing the bottom plate 51 is provided with a magnet 521; or a magnet is provided on the base plate 51, and a hall sensor is provided on the key 52 toward one side of the base plate 51. When the pressure carried by the cushion part above the key 52 reaches a preset pressure value, the key 52 is pressed and drives the magnet to approach the hall sensor, so that the hall sensor outputs a first signal. The elastic component 53 is disposed on the bottom plate 51, and is used for bouncing the key 52 to drive the magnet away from the hall sensor, so that the hall sensor outputs a second signal.

For another example, the first sensor may have a structure shown in fig. 6, that is, the first sensor includes a first switch assembly a, a second switch assembly B, a pivot O, and a cover plate C. The pivot is fixed to be set up on bottom plate, and first switch subassembly A, second switch subassembly B set up respectively in pivot O's both sides, and apron C passes through pivot movably setting on pivot O. When the pressure borne by the cushion part above the first switch component A is greater than the pressure borne by the cushion part above the second switch component B, the cover plate above the first switch component A is pressed down, and the key of the first switch component A is driven to be pressed down. That is, in the second sensor shown in fig. 6, two switch assemblies form a teeter-totter structure.

The first and second switching assemblies a and B in fig. 6 may have the same structure, and the first and second switching assemblies a and B may have the structure shown in any one of fig. 4A, 4B, and 5.

In some embodiments, two first sensors as shown in fig. 6 may be disposed on the symmetry axis of the seat cushion. When the cover plate of the first sensor X, Y assumes the condition shown in fig. 7A, i.e., the cover plates are all free from tilting, it indicates that no person is riding; when the cover of the first sensor X, Y assumes the condition shown in fig. 7B, i.e., the cover is tilted outside, it indicates that a person is riding; when the cover of the first sensor X, Y assumes the condition shown in fig. 7C, i.e., the outside of the cover is depressed, two persons are shown riding. The controller may determine the state assumed by the cover plate of each first sensor according to the output values of the two switch assemblies in each first sensor.

In some embodiments, two first sensors and one switch sensor may be disposed on the symmetry axis of the seat cushion, wherein the switch sensor is located between the two first sensors. When the three sensors show the situation shown in fig. 8A, that is, the KEY of the switch sensor KEY2 is sprung, and the cover plates of the first sensors KEY1 and KEY3 are not tilted, no one is shown to take the bus; when the three sensors show the situation as shown in fig. 8B, that is, the outer sides of the first sensors KEY1 and KEY3 are pressed down, it is indicated that two persons are riding, and the state of the switch sensor KEY2 does not affect the judgment result; when the three sensors take the situation shown in fig. 8C, i.e., the outer sides of the first sensors KEY1 and KEY3 are tilted and the KEY of the switch sensor KEY2 is pressed, it is indicated that there is one person riding. The controller may determine the state assumed by the cover plate of the first sensor based on the output values of the two switch assemblies in the first sensor, and determine whether the switch sensor is pressed based on the output values of the switch sensors.

In some embodiments, the sensor may be a second sensor that outputs a switching signal.

For example, the second sensor may be of a structure as shown in fig. 9A and 9B, that is, the second sensor includes a bottom plate 91, an elastic member 92, a cover plate 93, a variable resistor 94, and a circuit board 95. The bottom plate 91 is fixedly disposed in a cavity below the seat cushion, and the elastic member 92 may be a spring, a shrapnel, or the like. The first end of the elastic member 92 is disposed toward the bottom plate 91, and the cover plate 93 is disposed at the second end of the elastic member. Wherein a first end of the elastic member 92 is disposed on the bottom plate 91 and/or a second end of the elastic member 92 is fixedly disposed on the cover plate 93. The elastic member 92 may be a spring, a leaf spring, or the like.

The variable resistor 94 may be a slide rheostat, potentiometer, or the like. The variable resistor 94 has a movable portion, and the movable portion may be, for example, a slide of a slide rheostat, or may be, for example, a rotation shaft of a rotary potentiometer (the rotation shaft is selected from different angles to be different positions), a push-pull member of a push-pull potentiometer, or the like. When the position of the movable part is changed, the resistance thereof is also changed. The movable portion of the variable resistor 94 can move in synchronization with the cover plate 93 or the elastic member. For example, a clamping device is fixedly arranged on the cover plate 93, and clamps the movable part of the variable resistor 94, so that the cover plate 93 can drive the movable part to move when being pressed down or sprung up; or a clamping device is arranged on the spring at a position close to the cover plate 93, and clamps the movable position of the variable resistor 94, so that the movable position is driven to move when the spring is compressed.

The circuit board 95 is provided with a signal conditioning circuit connected to the variable resistor 94 for converting the resistance value of the variable resistor 94 into an analog voltage signal or an analog current signal to be output. It can be seen that the sensor shown in fig. 9A and 9B is capable of outputting an analog signal.

The controller determines the number of passengers according to the output signals of the sensors, and comprises the following steps: and according to the positions of the sensors on the symmetrical axes of the seat cushion, the output values of the sensors are corresponding to the symmetrical axes of the seat cushion, the number of the maximum values in the output values of the sensors on the symmetrical axes of the seat cushion is determined, and the number of the maximum values with the values larger than a preset threshold value is used as the number of passengers. In determining the maximum value, it is assumed that one virtual sensor is further provided on the outer sides of the two sensors on the upper edge of the seat cushion symmetry axis, respectively, and the values output by the two virtual sensors are 0, that is, the values on the outer sides of the two sensors on the upper edge of the seat cushion symmetry axis are 0. The preset threshold value is used for distinguishing whether an adult or a child sits on the cushion part corresponding to the maximum value point. The detailed description may be involved in the description of the pressure sensor portion.

In some embodiments, the second sensors may also be distributed in a curved surface. The plane is a special curved surface, so that, taking the case of a plane as an example, a planar plate body is arranged below the seat cushion, and a plurality of second sensors are arranged on the plate body, for example, the plurality of second sensors can be distributed symmetrically along the symmetry axis as shown in fig. 3B, and one dot in the figure represents one sensor. Accordingly, the controller determines the number of passengers based on the output signals of the plurality of sensors, including: and according to the positions of the sensors on the plane plate body, corresponding the output values of the sensors to the plane plate body, determining the number of maximum values in the output values of the sensors on the plane plate body, determining the number of maximum values on one side of a symmetrical axis of the cushion, and taking the number of maximum values with the value larger than a preset threshold value as the number of passengers. Wherein the predetermined threshold is used to distinguish whether an adult or a child sits on the cushion position corresponding to the maximum point.
