Description

Technical Field

[0001] The present invention relates to the technical field of battery auxiliary devices, in particular to a battery auxiliary device for an electric power-assisted vehicle. Background Art

[0002] When the battery of an electric power-assisted vehicle is used for a long time, the internal chemical reaction may cause the outer shell to bulge, rupture, and leak, causing short circuit, overheating, or even fire and explosion. For example, when a bulging battery is squeezed and ruptured during riding, the leaked corrosive electrolyte will damage vehicle components and users. As the use time increases, the battery capacity decays and the internal resistance increases, resulting in longer charging time, shorter cruising range, and insufficient power. Daily inspections can promptly detect signs of performance degradation, and timely replacement of the battery can restore the normal performance of the vehicle and meet travel needs. Moreover, the output voltage of a battery in poor condition is unstable, which will damage important components such as the controller and motor. Daily inspections and replacement of batteries when necessary can avoid battery problems from affecting other components, extend the service life of the vehicle, and save use costs. Regular inspections and replacement of batteries can help to recycle and dispose of them in accordance with regulatory requirements and reduce environmental pollution. Finally, daily inspections and timely replacement of batteries can effectively avoid battery failure during riding and ensure smooth and safe travel.

[0003] The Chinese patent with publication number CN106347567A discloses a battery lifting device and an electric bicycle. The electric bicycle comprises a frame and the battery lifting device. The battery lifting device is arranged on the frame and comprises a fixed bracket, a battery holder, a restoring force device and a locking device. The fixed bracket is used to support the battery. The battery holder is used to carry the battery and can move relative to the fixed bracket along a lifting path; the restoring force device is connected to the battery holder to provide power for the battery holder to rise relative to the fixed bracket. The locking device can be selectively in an unlocked state and a locked state. When the locking device is in the locked state, the locking device interferes with the battery to limit the movement of the battery relative to the fixed bracket. When the locking device is in the unlocked state, the locking device releases the interference with the battery, and the battery holder is driven by the power provided by the restoring force device to rise relative to the fixed bracket, thereby facilitating the user to remove the battery.

[0004] However, the existing battery auxiliary devices for electric power-assisted vehicles require the entire battery body to be disassembled for observation, whether for daily inspection or for in-depth inspection and replacement of the battery body. Frequent disassembly may cause collision between the battery body and vehicle components, damage the battery body shell and the vehicle installation part, reduce the performance and life of both, and have high requirements on user skills and tools. Improper operation may easily cause new faults. In emergency scenarios such as outdoor, it is difficult to operate without suitable tools and environment, affecting the normal use of the vehicle. Moreover, it will increase the maintenance cost due to component damage. If the battery body is scrapped, a new battery body needs to be purchased, further increasing the burden of use.

[0005] Therefore, a battery auxiliary device for an electric power-assisted vehicle is needed to solve the problem of not frequently disassembling and assembling the battery body during daily inspection or deep maintenance and replacement of the battery body. Summary of the invention

The push plate 94 drives the side plate 17 and the battery body 8 to move to the side close to the top of the bracket 1 through the support plate 97, so that the battery body 8 and the lower seat 7 are separated; when the baffle 2 and the bracket 1 are 45 degrees, the upper seat 6, the battery body 8 and the clamping piece begin to separate, and the upper seat 6 continues to move to the side close to the top of the bracket 1. The battery body 8 and the clamping piece move to the side of the inner side of the bracket 1 under the movement of the guide plate 95; Specifically, the clamping member includes two side plates 17, and the two side plates 17 are slidably clamped on the inner sides of two guide plates 95 located in the same horizontal plane.

At this time, the upper seat 6 and the lower seat 7 re-connect the new battery body 8. Finally, the staff rotates the rotating part 3 in the opposite direction, and the rotating part 3 drives the moving frame 42 to return to its original position. The moving plate 18 is separated from the upper seat 6, and the block 123 squeezes the transmission rod 10 to return to its original position under the action of the spring.

[0055] Working principle: The staff rotates the rotating member 3 in the positive direction for one circle, and the movable frame 42 is moved away from the top of the latch 11 to release the restriction on the baffle 2, and at the same time, the upper seat 6 and the movable plate 18 are connected together through the connecting rod 5; Then the staff pulls the baffle 2, the threaded rod 91 drives the engagement block 19 and the push plate 94 to move, and the moving plate 18 drives the upper seat 6 to move to the side close to the top of the bracket 1 through the connecting rod 5. When the baffle 2 and the bracket 1 are at 90 degrees, the upper seat 6 is completely separated, and the staff can check the appearance of the battery, etc.; The staff rotates the rotating member 3 in the positive direction for two turns, and the moving frame 42 is moved away from the top of the latch 11 to release the restriction on the baffle 2, and at the same time the upper seat 6 and the moving plate 18 are connected together, and the moving frame 42 drives the pressing plate 44 to squeeze the transmission rod 10, and the bottom of the transmission rod 10 contacts the bottom of the guide rail 121; Then the staff pulls the baffle plate 2, and the support plate 97 moves to the side close to the threaded rod 91 under the action of elastic force, closing the bottom of the push plate 94, and the push plate 94 continues to move to the side close to the top of the bracket 1. The push plate 94 drives the side plate 17 and the battery body 8 to move to the side close to the top of the bracket 1 through the support plate 97, so that the battery body 8 and the lower seat 7 are separated; When the baffle plate 2 is at 45° with the bracket 1, the upper seat 6, the battery body 8 and the clamping member begin to separate, and the battery body 8 and the clamping member move to one side of the inner side of the bracket 1 under the movement of the guide plate 95; When the baffle 2 and the bracket 1 are at 90°, the battery body 8 moves to the top of the connection between the baffle 2 and the bracket 1, the staff presses the clamp 15 to release the restriction on the battery body 8, and replaces the battery body 8. After the new battery is replaced, the staff drives the baffle 2 to return to its original position at a uniform speed, and finally the staff rotates the rotating part 3 in the opposite direction, and the rotating part 3 drives the moving frame 42 to return to its original position, the moving plate 18 is separated from the upper seat 6, and the block 123 squeezes the transmission rod 10 to return to its original position under the action of the spring.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
