Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, the present utility model provides an electric vehicle. The interior of the electric vehicle 100 may include various management systems, which may include, for example, a BATTERY management system (BATTERY MANAGEMENT SYSTEM, BMS), a vehicle thermal management system 200 (THERMAL MANAGE SYSTEM, TMS), and the like. Through the mutual cooperation of various management systems, the stable operation of each device in the electric automobile 100 is realized. Taking the automobile thermal management system 200 as an example for illustration, the automobile thermal management system 200 can reasonably manage the temperatures of the driving motor system, the power battery and the passenger cabin, thereby ensuring the safe operation of the power battery to the greatest extent and improving the utilization efficiency of the power battery.

Specifically, the input signals of the automobile thermal management system 200 may include a temperature sensor signal, an air conditioner switching signal, a defrost switching signal, a water pump rotational speed PWM signal, a BMS status information bus signal, an MCU status information bus signal, an EMS status information bus signal, and the like. The output signals of the automotive thermal management system 200 may include a switch for a PTC relay, a switch for an air conditioner compressor relay, a switch for a fan relay, a switch for a water pump relay, a switch for a switching solenoid valve, a switch for an electronic thermostat, a water pump rotational speed command, TMS status information, etc. Because the automobile thermal management system 200 needs to control the on-off of multiple loops, the automobile thermal management system 200 can control the on-off of different loops by controlling the on-off of different multi-way valves 300, thereby completing the work of temperature management.

Referring to fig. 2 and 4, in one embodiment of the present utility model, the multi-way valve 300 may include a valve cover assembly, a adapter block 40, a valve core 50, an upper ceramic valve plate 60, a lower ceramic valve plate 70, and a valve body 90. Wherein the valve cap assembly cooperates with the valve body 90 to form an interior cavity. The adapter block 40 and valve cartridge 50 may be located in the interior cavity and connected to the valve cover assembly. The valve cover assembly can drive the valve core 50 to rotate through the adapter block 40, so that the valve core 50 can be rotatably arranged in the inner cavity. The upper ceramic valve plate 60 may be mounted on the valve core 50, and the upper ceramic valve plate 60 may rotate along with the rotation of the valve core 50, so as to achieve the relative fixation of the upper ceramic valve plate 60 and the valve core 50. The lower ceramic valve plate 70 may be mounted on the valve body 90 to achieve relative fixation of the lower ceramic valve plate 70 and the valve body 90. The upper ceramic valve plate 60 and the lower ceramic valve plate 70 can be closely attached.

Friction occurs between two objects in contact with each other when the objects move or tend to move relative to each other along the tangential direction of the contact surfaces. Because the upper ceramic valve plate 60 and the lower ceramic valve plate 70 are made of ceramics, the low friction coefficient and the wear performance of the ceramics are good. On the contact surface of the upper ceramic valve plate 60 and the lower ceramic valve plate 70, sealing between the ceramic surfaces can be realized due to the negative pressure of the microstructure. Therefore, the service lives of the upper ceramic valve plate 60 and the lower ceramic valve plate 70 can be effectively prolonged, and the sealing performance of the contact surface of the upper ceramic valve plate 60 and the lower ceramic valve plate 70 can be maintained.

The size of the region formed by the first water through holes 901 and the second water through holes 902 is the same as the size of the third water through holes 903. The valve body 90, the valve core 50, the upper ceramic valve plate 60 and the lower ceramic valve plate 70 cooperate to form a plurality of loops, and the loops correspond to the channels on the valve core 50. Under the operation of the actuator 10, the valve core 50 can be driven to rotate relatively to the valve body 90, so as to drive the upper ceramic valve plate 60 and the lower ceramic valve plate 70 to rotate relatively. At this time, the through openings on the upper ceramic valve plate 60 and the through openings on the lower ceramic valve plate 70 are relatively shifted, and thus the circuit in the multi-way valve 300 is changed to a certain extent. Therefore, as the actuator 10 rotates the valve element 50 by a certain angle, the circulation circuit in the multi-way valve 300 changes by a certain amount.

Referring to fig. 16, in an embodiment of the present utility model, when the valve body 90 and the valve core 50 rotate relatively, and the angle of the relative rotation reaches the preset angle, the path of the circuit is changed, so that the multi-way valve 300 enters different working modes. In different operation modes, the correspondence between the through openings of the upper ceramic valve plate 60 and the through openings of the lower ceramic valve plate 70 is different.

That is, when the spool 50 is in the initial position, the multi-way valve 300 enters the first operation mode. When the spool 50 rotates 22.5, the multi-way valve 300 enters the second mode of operation. When the spool 50 rotates 45, the multi-way valve 300 enters the third operating mode. When the spool 50 rotates 67.5 deg., the multi-way valve 300 enters the fourth operating mode. When the spool 50 rotates 90 deg., the multi-way valve 300 enters the fifth mode of operation.

When spool 50 rotates 202.5, multiport valve 300 enters a tenth operating mode. When the spool 50 rotates 225 deg., the multi-way valve 300 enters the eleventh operating mode. When the spool 50 rotates 247.5 deg., the multi-way valve 300 enters the twelfth mode of operation. When the spool 50 rotates 270 deg., the multi-way valve 300 enters the thirteenth operating mode. When spool 50 rotates 292.5, multiport valve 300 enters a fourteenth operating mode. When the spool 50 rotates 315, the multi-way valve 300 enters the fifteenth operating mode. When spool 50 rotates 337.5, multiport valve 300 enters a sixteenth mode of operation. When the spool 50 rotates 360, i.e., the spool 50 returns to the original position, the multi-way valve 300 reenters the first operating mode.

Referring to fig. 11, 12 and 16, in one embodiment of the present utility model, four circuits may be formed in the multi-way valve 300 when the multi-way valve 300 enters the first operation mode.

Table 16: sixteenth mode of operation

Therefore, in the scheme, on the contact surface of the upper ceramic valve plate and the lower ceramic valve plate, the ceramic surfaces can be tightly attached due to the negative pressure of the microstructure, so that the valve core of the multi-way valve is effectively prevented from tilting and rollover in the working process, and the service life of the multi-way valve is prolonged. The split type design is adopted between the ceramic valve block and the valve core, so that the processing difficulty of the ceramic valve block is reduced. In the process of switching the inner loop of the multi-way valve, the friction force between the upper ceramic valve plate and the lower ceramic valve plate is small, the switching of the loop can be smoothly completed, and meanwhile, the abrasion of the valve plates is small. Meanwhile, the single multi-way valve can be used for switching different loops, the single multi-way valve can be used for replacing a plurality of three-way valves and four-way valves, the number of valves in an automobile thermal management system can be effectively reduced, the cost is reduced, and when different loops are switched, the loop switching efficiency can be increased along with the increase due to the fact that only the single multi-way valve is required to be switched.
