Description

Technical Field

[0001] The utility model relates to the technical field of battery boxes for electric power-assisted vehicles, and in particular to a novel battery box for electric power-assisted vehicles. Background Art

[0002] At present, the development of battery boxes in the field of battery technology is moving towards a direction of simplicity, convenience, beauty and cost reduction; Patent No. CN201922008478.X discloses a new type of electric power-assisted bicycle battery box, which has a simple and clear structure, is easy to assemble, easy to produce, has a small number of components, and leaves a lot of space inside the battery box for placing batteries; the transparent power display lampshade is convenient for observing the power; however, since there is no good protective structure inside the battery box, the shock absorption effect of the battery box is not good. If there is a collision, the force of the collision directly impacts the battery body inside the battery box, which is easy to cause certain effects on the battery. To this end, we propose a new type of electric power-assisted bicycle battery box. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a novel battery box for an electric power-assisted bicycle.

[0004] The technical solution adopted by the utility model to solve the technical problem is a new type of battery box for electric power-assisted vehicles, comprising an outer shell and a battery body, wherein a frame shell for auxiliary support is clamped on the inner side of the outer shell, and a card slot for connection is opened on the inner peripheral surface of the frame shell, and there are multiple groups of card slots, and a card seat for connection is integrally constructed on the outer peripheral surface of the battery body, and there are multiple groups of card seats, and the card seat and the inner side of the card slot are both opened and closed with gasket strips, and a silicone strip is installed between two groups of the gasket strips;

[0005] The top surface of the shell is assembled with a top cover by screws, and the bottom surface of the shell is assembled with a bottom cover by screws. A shock-absorbing pad for protection is bonded to one end of the inner circumference of the shell close to the top.

[0006] By adopting the above technical solution, when the battery box of the electric power-assisted vehicle is used, the two groups of pads and the silicone strips between the inner frame shell of the outer shell and the battery body cooperate with each other, so as to protect the battery body, and the silicone strips have certain shock-absorbing performance, so as to provide certain buffering performance for the battery body when shock occurs, and at the same time cooperate with the upper frame shell to improve the strength of the outer shell, so that the battery body can operate more stably, and the pads are mutually engaged and connected with the card seat and the card slot, so as to facilitate disassembly and assembly, so that the battery body can be easily disassembled, replaced, and maintained;

[0007] When the battery body is installed inside the outer shell, it is convenient to install the top cover and the bottom cover at both ends of the outer shell, so as to seal the open ends on both sides of the outer shell. At the same time, the shock-absorbing pad on the inside of the top cover can provide a certain shock-absorbing performance, so that the battery body inside the outer shell can operate more stably, and can provide a certain buffering protection performance when bumps occur.

[0008] Specifically, a ring groove for storage is provided on a side of the bottom cover close to the battery body, and a memory foam body abutting against the battery body is bonded to the inner side of the ring groove.

[0009] By adopting the above technical solution, the memory foam body on the inner side of the groove is easy to expand and contract, which is convenient for buffering and protecting the bottom cover and the battery body, and is convenient for reducing the damage caused by collision between the battery body and the bottom cover.

[0010] Specifically, a spring A located inside the silicone strip is installed between the two groups of the gasket strips.

[0011] By adopting the above technical solution, the spring A can provide a certain elasticity, so that the silicone strip can return to its original position after contraction, thereby improving the buffering performance of the silicone strip.

[0012] Specifically, springs B are installed on the inner side of the shock-absorbing pad and the inner side of the memory foam body.

[0013] By adopting the above technical solution, the spring B can conveniently provide a certain buffering performance for the memory foam body, so that the memory foam body can return to its original position after shrinking, thereby improving the limiting protection performance of the memory foam body on the battery body.

[0014] Specifically, the outer peripheral surface of the top cover is provided with grooves, and there are two groups of grooves.

[0015] By adopting the above technical solution, the pull groove makes the battery box easy to pull and more convenient to disassemble and assemble.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of the outer shell, battery body, frame shell, slot, holder, pad and silicone strip. When the battery box of the electric power-assisted vehicle is used, the two groups of pads and the silicone strip between the inner frame shell of the outer shell and the battery body cooperate with each other to protect the battery body. The silicone strip has a certain shock-absorbing performance, which is convenient for providing a certain buffering performance for the battery body when shock occurs. At the same time, it cooperates with the upper frame shell to improve the strength of the outer shell, so that the battery body can operate more stably. The pad is mutually engaged and connected with the holder and the slot for easy disassembly and assembly, so that the battery body can be easily disassembled, replaced, and maintained.

[0018] 2. The technical solution of the present application, through the design of the top cover, bottom cover and shock-absorbing pad, makes it convenient to install the top cover and the bottom cover at both ends of the outer shell when the battery body is installed inside the outer shell, so as to seal the open ends on both sides of the outer shell. At the same time, the shock-absorbing pad on the inside of the top cover can provide a certain shock-absorbing performance, so that the battery body inside the outer shell can operate more stably, and can provide a certain buffering protection performance when bumps occur.
