Moreover, the locking assembly 4 ensures that the upright assembly 3 and the hub part 101 are relatively fixed when the upright assembly 3 is in the unfolding position, and ensures the running stability of the electric scooter. Moreover, the locking assembly 4 can release the connection between the standing assembly 3 and the hub part 101, so that the standing assembly 3 rotates to a folding position relative to the hub part 101, thereby reducing the height of the electric scooter and facilitating the storage of the electric scooter.
For convenience of understanding, arrow a in fig. 1 and 2 shows the left-right direction of the standing folding mechanism according to the embodiment of the present invention, arrow B in fig. 2 shows the up-down direction of the standing folding mechanism according to the embodiment of the present invention, and arrow C in fig. 1 shows the left-right direction of the standing folding mechanism according to the embodiment of the present invention.
In some embodiments, the locking assembly 4 includes a support member 401 and a locking member 402. The support 401 is connected to the hub portion 101, and a locking groove 4011 having an open upper end is formed on the support 401. The locking member 402 includes a locking pin portion 4021, the lower end of the handle assembly 3 is provided with a long hole 303, and the locking pin portion 4021 is slidably fitted in the long hole 303. The lock pin portion 4021 can slide in the longitudinal direction of the long hole 303 to be removed from and inserted into the lock groove 4011.
Specifically, the cross-sectional shape of the locking groove 4011 is U-shaped, and the sum of the length of the locking groove 4011 and the dimension of the lock pin portion 4021 in the length direction of the long hole 303 is smaller than the length of the long hole 303. When the standing component 3 is in the unfolding position, the length direction of the locking groove 4011 is consistent with the length direction of the long hole 303, therefore, the locking pin 4021 can be matched in the locking groove 4011 by sliding along the length direction of the long hole 303, so that the standing component 3 and the hub part 101 can be relatively fixed, and the locking groove 4011 can also be disengaged, so that the standing component 3 can be conveniently rotated relative to the hub part 101, and the electric scooter can be conveniently folded and stored.
In some embodiments, the handlebar stem assembly 3 includes a body 301 and two vertical plates 302 disposed at the lower end of the body 301, the two vertical plates 302 are spaced apart in the left-right direction, at least one of the two vertical plates 302 is provided with a long hole 303, and the two vertical plates 302 are pivotally connected to the hub portion 101 by a second pivot and are respectively disposed at the left side and the right side of the hub portion 101.
Specifically, two vertical plates 302 are provided with long holes 303, and the lock pin portions 4021 correspond to the long holes 303 one by one. The support 401 includes two support portions 4012, the two support portions 4012 are connected to the hub portion 101 and are located at left and right sides of the hub portion 101, respectively, and the locking groove 4011 is provided at upper ends of the two support portions 4012. Accordingly, the stand unit 3 is coupled to the support portion 4012 by the two lock pin portions 4021, so that the stand unit 3 is coupled to the hub portion 101 at a higher strength when in the deployed position, and the electric scooter is higher in driving stability.
Wherein, two supporting portions 4012 are platelike structure, and all be equipped with two connecting holes along hub portion 101's circumference spaced apart on every supporting portion 4012, and the left surface and the right flank of hub portion 101 all are equipped with the screw hole with the connecting hole one-to-one. The bolts pass through the respective coupling holes and are screw-engaged with the respective screw holes, whereby the coupling of the support portion 4012 and the hub portion 101 is achieved with high coupling strength therebetween. The support portion 4012 is interposed between the hub portion 101 and the corresponding upright plate 302, and the second pivot shaft passes through the support portion 4012 and is positioned above the steering shaft 5. Therefore, when the standing component 3 is positioned at the folding position, the highest height of the standing component 3 can be smaller than that of the front wheel 1, the electric scooter is generally in a straight flat posture, and the electric scooter occupies smaller space and is more convenient to store.
In some embodiments, the locking member 402 further includes a first connecting portion 4022, two locking pin portions 4021 are respectively connected to the left end and the right end of the first connecting portion 4022, the locking pin portions 4021 have a waist-shaped cross section, the length direction of the waist-shaped cross section is identical to the length direction of the long hole 303, and the first connecting portion 4022 is located between the two vertical plates 302.
As shown in fig. 6, the first connector 4022 is a U-shaped bracket, and at least a portion of the front wheel 1 fits in a U-shaped groove formed by the first connector 4022. Therefore, when the locking groove 4011 on the supporting portion 4012 is lower than the highest height of the front wheel 1, the locking pin portion 4021 can be matched in the locking groove 4011, the supporting portion 4012 does not need to protrude upwards out of the front wheel 1, the supporting portion 4012 is small in size, the locking assembly 4 is more compact in structure, and the occupied space is small.
Moreover, by arranging the lock pin portion 4021 to be waist-shaped in cross section, when the lock pin portion 4021 is released from the lock slot 4011, the lock pin portion 4021 engaged in the long hole 303 cannot rotate relative to the vertical plate 302, and the lock pin portion 4021 is ensured to slide back and forth only relative to the vertical plate 302 along the length direction of the long hole 303.
Of course, the entire locking member 402 may be provided, as long as the support member 401 is sized large enough to keep the front wheel 1 below the first connector 4022.
In some embodiments, the support member 401 further includes a second connection portion 4013, upper ends of the two support portions 4012 are connected to left and right ends of the second connection portion 4013, respectively, and the locking groove 4011 penetrates the second connection portion 4013 in the left-right direction. This reduces the difficulty of mounting the support member 401 on the hub portion 101, and also improves the strength of connection between the support member 401 and the hub portion 101.
