Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The embodiment of the power battery installation structure of the present invention, as shown in Figures 1 to 3, the power battery installation structure includes a mounting frame 3 for connecting with the vehicle frame and a battery box 1 for fixing the power battery, and the mounting frame 3 There is a mounting groove for slidingly assembling the battery box 1 on the top. The opening of the mounting groove is provided with a locking groove 31 with the opening facing the middle of the mounting groove. The battery box 1 is hingedly equipped with a locking lever 5. The locking lever 5 has a locking end 51 that hangs into the locking groove 31 and an operating end that extends away from the locking end 51. When locking, the locking end 51 and the upper groove wall 32 of the locking groove 31 are locked and limited. 1. The operating end is connected to the battery box 1 through screws 6. When unlocking, the operating end is separated from the battery box 1 and operated to move in the direction of the principle battery box 1. The locking end 51 is pushed against the lower groove wall 33 of the locking groove 31. Press fit to pry the battery compartment 1 open.

In this embodiment, the locking end 51 is rotatably equipped with a roller 52, the friction force between the locking rod 5 and the locking groove 31 can be reduced by the roller 52, and the friction between the locking rod 5 and the locking groove 31 can be avoided. damage to the structure.

In order to facilitate the installation of the roller 52, in this embodiment, the locking end 51 is provided with a limiting groove 53, and two opposite groove walls of the limiting groove 53 are provided with positioning holes, and the roller 52 is arranged in the limiting groove 53 and The two ends of the rotating shaft are correspondingly assembled in the two positioning holes. Adopting this structure can limit the position of both ends of the roller 52, and at the same time, the support at both ends improves the structural strength of the support.

In order to facilitate the movement of the battery box 1 in the installation groove, in this embodiment, balls 4 for the rolling fit of the battery box tube are distributed on the wall of the installation groove. When the battery box is installed or disassembled, the battery box rolls with the ball 4 on the wall of the installation groove to reduce the friction between the battery box and the installation groove. In order to prevent the balls 4 from causing damage to the side wall of the battery case, the number of the balls 4 is set in multiples, so as to reduce the pressure of a single ball 4 in contact with the side wall of the battery case.

In this embodiment, the side of the locking rod is a hollow structure, and the hollow structure is provided with reinforcing ribs 55 for increasing the structural strength. Adopting the hollow structure can reduce the overall weight of the locking rod. The rear end of the locking rod is provided with a screw mounting hole 54 for mounting screws. Specifically, the screw mounting hole 54 is a stepped hole, which is convenient for screw mounting.

In this embodiment, the size of the upper groove wall 32 of the locking groove 31 is smaller than that of the lower groove wall 33 for the locking end 51 of the locking rod to pass up and down.

In order to ensure the structural strength of the battery box, in this embodiment, the battery box includes a battery box body and a guide bar 2 arranged outside the battery box body. The battery box body slides and fits with the groove wall of the installation groove through the guide bar 2. Play the role of reinforcing ribs 55, thereby ensuring the overall structural strength of the battery box.

When the power battery installation structure of the present invention is locked, the locking end and the upper groove wall 32 of the locking groove 31 are locked and limited, and the operating end is connected to the battery box by screws. When unlocking, the operating end is separated from the battery box. And operate it to move away from the direction of the battery box, the locking end and the lower groove wall 33 of the locking groove are press-fitted to pry the battery box, and the locked connection between the battery box and the mounting frame 3 can be realized through the locking lever. At the same time, during the dismounting process, the locking lever is press-fitted with the lower groove wall 33 of the locking groove, so that the locking lever acts as a crowbar. Large frictional force, thereby avoiding the battery box from being stuck, and solving the problem of inconvenient disassembly of the existing power battery installation structure.

In other embodiments of the present invention, the locking end of the locking rod can also be arranged in an arc-shaped structure, which reduces the number of parts and costs; the ball can also be arranged on the guide bar; the locking rod can also be It is set as an integrated solid structure; it is also possible to install and cooperate directly through the side wall of the battery box without setting the guide bar.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
