[specific embodiment]
The structure and principle of the utility model embodiment knee lock are as shown in Figures 1 to 8, including lock box, lockable mechanism, electricity
The latch hook 1 that machine 3, control circuit and two are arranged symmetrically, mutually link.
The middle part of latch hook 1 is hinged by the bottom plate 10 of articulated shaft 11 and lock box, and motor 3 is mounted on bottom plate 1.
The lower part of latch hook 1 is gib head 101, and the top of latch hook 1 is linkage portion 102, has one in the linkage portion 102 of right latch hook 1A
A sliding pin 103 has an arc groove 104 in the linkage portion 102 of left latch hook 1B, and sliding pin 103 is inserted into arc groove 104,
The two is slidably matched, and guarantees that two latch hooks can be opened and closed simultaneously with coordination.
1 upper inner of latch hook is equipped with idler wheel 12.Two 13 sets of torsional springs are respectively in hinged hinged of two latch hooks 1 and bottom plate 10
On axis 11, the tension of torsional spring 13 opens two latch hooks 1.
The lockable mechanism of latch hook includes that elastic lock bolt and card wheel 2, card wheel 2 are fixed on the main shaft of motor 3, by 3 band of motor
Dynamic rotation.
Elastic lock bolt includes lock bolt 4 and pressure spring 5, there is the latch hole 106 of a upward opening, pressure spring at the top of right latch hook 1A
5 are arranged in latch hole 106, and the lower part of lock bolt 4 is inserted in the pressure spring of latch hole 106, and the head of lock bolt 4 is pressed in the top of pressure spring 5
Portion.There is the inclined-plane 401 towards outside on the head of lock bolt 4.
There are one pressing plates 202 outstanding forward, with rotation axis off-center for 2 front of card wheel.Control circuit includes being used for
Open that the switch 21 of motor forward driving circuit, the switch 22 for disconnecting motor forward driving circuit, to be used to open motor anti-
Switch 23 to the trigger circuit of driving circuit and for disconnecting motor reverse driving circuit.
Switch 21 is fixed on bottom plate 10, is arranged in the rear on the top left latch hook 1B.The front-wheel of bicycle is pushed into two locks
In neutral gear between hook 1, front-wheel pushes the idler wheel 12 on the inside of latch hook, is closed two latch hooks 1.When the gib head 1 of latch hook 1 closes 1 conjunction,
It is opened outside top, the top of latch hook 1B is pressed on switch 21, is closed switch 21, and electric machine main shaft rotates forward.As shown in Figure 1, card
Flashboard 201 on wheel 2 goes to downwards the lower section of electric machine main shaft, blocks the head of lock bolt 4, keeps two latch hooks sealed, cannot separate,
Bicycle is lockked；If the flashboard 201 in card wheel 2 goes to downwards the lower section of electric machine main shaft, lock bolt 4 is then pressed into latch hole 106
It pops up again, limitation left and right latch hook is opened, thus Wheel lock for bicycle in two latch hooks.
