[0016] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0017] A kind of Figure 1-4The battery cover quick-release and quick-locking structure shown includes a first bracket 1, a second bracket 2, and a third bracket 3, wherein the top surface of the first bracket 1 is used to connect and fix the foot pedal, and the space under the foot pedal is the power battery installation space. One end of the first bracket 1 is limitedly connected or hingedly connected to the main pipe on one side of the frame 4, so as to facilitate the removal of the foot pedal as a whole or flip it open. The second bracket 2 is fixedly connected to the other end of the first bracket 1. The third bracket 3 is welded to the main pipe on the other side of the frame 4. A lock tongue 5 that limits the second bracket 2 is provided on the third bracket 3. The lock tongue 5 is elastically arranged on the third bracket 3, and a cable 6 is connected to the rear end of the lock tongue 5, and the cable head of the cable 6 is set in the electric vehicle seat barrel. A vertically arranged elastic top pin 7 is provided on the second bracket 2, and a support platform 8 in contact with the lower end of the elastic top pin 7 is provided on the third bracket 3.

[0018] A first guide limiter 9 is provided on the third bracket 3, the first guide limiter 9 has a first positioning groove, a second guide limiter 10 is provided in the first positioning groove, the second guide limiter 10 has a second positioning groove, the lock tongue 5 is horizontally slidably provided in the second positioning groove, the top surface of the second guide limiter 10 is provided with a cover plate 11, the cover plate 11, the second guide limiter 10 and the first guide limiter 9 are all connected to the third bracket 3 by screws.

[0019] The front portion of the first guide limiter 9 has a front support portion 91 that bends upward and supports the front portion of the lock tongue 5. The rear portion of the first guide limiter 9 has an extended support portion 92 that supports the rear portion of the lock tongue 5. The rear portion of the second guide limiter 10 has a first slot limiter 101 for the outer sleeve of the limit cable 6. The rear end of the lock tongue 5 has a second slot limiter 51 for the hammer head of the limit cable 6. A first spring 12 is provided between the first slot limiter 101 and the second slot limiter 51. The first spring 12 is sleeved on the steel wire of the cable 6.

[0020] Elastic ejector pin 7 includes a pin 71 vertically movably mounted on second bracket 2, with a nylon sleeve 75 disposed between second bracket 2 and pin 71. A second spring 72 is sleeved on pin 71, with the upper end of second spring 72 restrained by the bottom of second bracket 2 and the lower end restrained by the disc head of pin 71. The upper end of pin 71 protrudes from the top surface of second bracket 2 and is provided with a cotter pin 73, with a gasket 74 disposed below cotter pin 73.

[0021] The upper front end of the locking tongue 5 has an extrusion slope that contacts the second bracket 2 .

[0022] Locking principle: The foot pedal is placed in the appropriate position, with the second bracket 2 positioned above the lock tongue and the second spring 72 in its natural state. The foot pedal is not closed at this time. Applying a certain force above the foot pedal causes the second bracket 2 to move vertically downward. Simultaneously, the first and second springs are gradually compressed, and the lock housing 5 gradually moves to the left until the second bracket 2 moves past the lock housing 5. The lock tongue 5 then automatically returns to its original position under the action of the first spring. At this point, the second bracket 2 is below the lock tongue 5 and is compressed. Simultaneously, the second spring is compressed, exerting an upward force on the second bracket 2, locking it tightly. Because the second bracket 2 is connected to the foot pedal, the foot pedal is firmly secured.

[0023] Opening principle: Gently pull the cable head of the cable 6 installed in the seat bucket. The cable 6 moves to the left, driving the lock 5 to move to the left. The lock 5 compresses the first spring and moves to the left, no longer restricting the second bracket 2. At the same time, because the second spring is in a compressed state and is no longer restricted by the lock tongue 5, the second spring instantly returns to its natural length. By pushing the second bracket 2 out of the plane, since the second bracket 2 is connected to the foot pedal, the foot pedal is pushed out of the plane, which makes it easy to remove the foot pedal by hand, and the power battery can be quickly removed and replaced at the same time. After the power battery is replaced, repeat the locking action to firmly fix the foot pedal to the frame.

Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention.
