Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and particularly relates to a side-opening integrated cover battery mechanism. Background Art

[0002] In the current industry, the side-opening integrated cover battery mechanism solutions for Ebike (Electric Bicycle) mainly fall into two categories:

[0003] In the first solution, the battery housing is made of an aluminum cylinder. Each end of the aluminum cylinder has an eaves-like structure, which can shield the plastic end caps at both ends of the battery. Moreover, the aluminum cylinder can be subjected to the same surface treatment as the whole vehicle, achieving the effect of using the aluminum cylinder itself as the battery cover. This solution has corresponding drawbacks: after the battery drops, the aluminum cylinder is extremely prone to deformation, which will cause the battery to be unable to be installed on the vehicle. When repairing, the entire outer shell needs to be replaced. If the deformation is severe, the battery needs to be replaced.

[0004] In the second solution, the battery housing is made of a plastic shell, and a plastic cover is assembled on the plastic shell. The cover is mostly fixed to the battery shell by hooks and screws. This solution has corresponding drawbacks: since the plastic cover and the frame are made of different materials, generally the plastic shell uses the natural color of plastic particles combined with an etched texture effect, and the frame is painted. The effects presented after surface treatment cannot be made consistent, and the overall appearance of the vehicle is affected. Only a color-block design can be done; the plastic cover is generally fixed to the battery shell by hooks and screws and does not support multiple disassembly. After multiple disassembly, it is easy to cause the installation position of the battery housing to fail, resulting in scrapping. Content of the Utility Model

[0005] To overcome the above drawbacks, the purpose of the utility model is to provide a side-opening integrated cover battery mechanism to solve the problem that the installation position of the battery housing is likely to fail after the plastic cover is disassembled multiple times as mentioned in the above background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is a side-opening integrated cover battery mechanism, including:

[0007] A battery shell, extending along a first direction and having an opening at the top along a second direction, for placing a battery.

[0008] A cover, extending along the first direction and disposed above the battery shell, for closing the opening.

[0009] The limiting device includes a limiting section and guiding and limiting ribs. The limiting sections are respectively arranged on both sides of the battery case along the third direction, and the guiding and limiting ribs corresponding to the limiting sections are arranged on the side of the cover plate facing the battery case. When the cover plate closes the opening, the guiding and limiting ribs are clamped and fixed with the limiting sections, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0010] For the side-opening integrated cover plate battery mechanism provided by the present utility model, a limiting device is set to fix the cover plate and the battery case when the cover plate is closed. The guiding and limiting ribs are clamped and fixed in the limiting section, so that the cover plate and the battery case can be disassembled and installed multiple times, which is convenient for timely replacement and repair when the cover plate is deformed. At the same time, repeated installation multiple times will not affect the battery case, reducing the maintenance cost.

[0011] In some embodiments, a plurality of stop blocks are arranged at both ends of the opening along the third direction, the plurality of stop blocks are arranged at intervals along the first direction, and a limiting groove is arranged between each stop block and the battery case. Along the first direction, the plurality of limiting grooves form the limiting section.

[0012] Both ends of the cover plate along the third direction are respectively provided with a first bending part and a second bending part, and both the first bending part and the second bending part are bent towards the direction close to the battery case. The inner walls of the first bending part and the second bending part are both provided with the guiding and limiting ribs. The guiding and limiting ribs extend along the first direction and are correspondingly arranged with the limiting section.

[0013] By adopting the above technical solution, the limiting section formed by a plurality of limiting grooves extends along the first direction, and both ends of the cover plate along the third direction are bent towards the battery case direction, so as to cover above the opening, and the first bending part and the second bending part on both sides are convenient for arranging the guiding and limiting ribs.

[0014] In some embodiments, the limiting device further includes a collision-proof cover. The collision-proof cover is correspondingly arranged with the cover plate along the first direction and includes a connecting part, a third bending part, and a fourth bending part. The third bending part and the fourth bending part are respectively arranged on both sides of the connecting part along the third direction. The connecting part is provided with a first installation through hole and a positioning post at intervals on the side facing the cover plate along the first direction.

[0015] In some embodiments, along the first direction, a first male stop is arranged on the side of the third bending part facing the cover plate, and a second male stop is arranged on the side of the fourth bending part facing the cover plate. The first bending part is provided with a first female stop corresponding to the first male stop for concave-convex fitting and fixing with the first male stop. The second bending part is provided with a second female stop corresponding to the second male stop for concave-convex fitting and fixing with the first male stop.

[0016] With the above technical solution, through the concave-convex fit between the first female stop and the first male stop, and the concave-convex fit between the second female stop and the first male stop, the firmness and stability of the connection between the anti-collision cover and the cover plate are ensured.

[0017] In some embodiments, the limiting device further includes a first pressing piece.

The second mounting through hole is arranged corresponding to the position of the first mounting through hole. The positioning hole is arranged corresponding to the position of the positioning post for snap-fitting and fixing with the positioning post.

[0018] With the above technical solution, the first pressing piece serves as an intermediate component between the anti-collision cover and the cover plate, playing a buffering role.

[0019] In some embodiments, the limiting device further includes a second pressing piece. The second pressing piece is arranged parallel to the first pressing piece along the second direction. On the side of the second pressing piece facing the cover plate, a third mounting through hole is provided. At both ends of the cover plate along the first direction, threaded posts corresponding to the positions of the second mounting through hole and the third mounting through hole are respectively provided.

[0020] With the above technical solution, the anti-collision cover, the first pressing piece and the cover plate are fixedly connected by sequentially passing a bolt through the first mounting through hole and the second mounting through hole and threading it with the threaded post. The second pressing piece and the cover plate are fixedly connected by passing a bolt through the third mounting through hole and threading it with the threaded post.

[0021] In some embodiments, on both sides of the opening along the first direction, mounting steps adapted to the anti-collision cover, the first pressing piece and the second pressing piece are provided.

[0022] With the above technical solution, one end of the cover plate abuts and is limited by the anti-collision cover and the first pressing piece against the mounting step, and the other end abuts and is limited by the second pressing piece against the mounting step, so as to fix the cover plate and the battery case in the first direction.

[0023] In some embodiments, the cover plate is made of aluminum.

[0024] With the above technical solution, the material of the cover plate is the same as that of the vehicle frame, so the cover plate and the vehicle frame can be subjected to the same surface treatment without affecting the overall vehicle styling design. BRIEF DESCRIPTION OF THE DRAWINGS

The limiting sections are respectively disposed on both sides of the battery case 2 along a third direction ( Figure 1 shown in the Y direction in the figure), and the guiding and limiting ribs 32 are correspondingly disposed on the side of the cover plate 3 facing the battery case 2 with respect to the limiting section. When the cover plate 3 closes the opening 20, the guiding and limiting ribs 32 are clamped and fixed with the limiting section. The first direction, the second direction, and the third direction are perpendicular to each other.

[0035] For the side-opening integrated cover plate battery mechanism 1 provided in this application, a limiting device is provided to fix the cover plate 3 and the battery case 2 when the cover plate 3 is closed. The guiding and limiting ribs 32 are clamped and fixed in the limiting section, enabling the cover plate 3 and the battery case 2 to be disassembled and installed multiple times. This facilitates timely replacement and repair when the cover plate 3 is deformed. At the same time, repeated installation multiple times will not affect the battery case 2, reducing the maintenance cost.

[0036] In some embodiments, referring to Figure 1 and Figure 2 , a plurality of stop blocks 40 are provided at both ends of the opening 20 along the third direction. The plurality of stop blocks 40 are spaced along the first direction, and a limiting groove 41 is provided between each stop block 40 and the battery case 2. Along the first direction, the plurality of limiting grooves 41 form a limiting section.

[0037] The two ends of the cover plate 3 along the third direction are respectively provided with a first bending portion 30 and a second bending portion 31. The first bending portion 30 and the second bending portion 31 are both bent towards the direction close to the battery case 2. Guide and limit ribs 32 are provided on the inner walls of the first bending portion 30 and the second bending portion 31. The guide and limit ribs 32 extend along the first direction and are correspondingly arranged with the limiting section.
