Power battery installation structure

Abstract

The present invention relates to a power battery installation structure. When the power battery installation structure of the present invention is locked, the locking end and the upper groove wall of the locking groove 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 operated to move in a direction away from the battery box. The locking end and the lower groove wall of the locking groove are pressed together to pry the battery box. The locking connection between the battery box and the mounting frame can be achieved through the locking rod. At the same time, during the disassembly process, the locking rod and the lower groove wall of the locking groove are pressed together, so that the locking rod plays the role of a pry bar. Under the reaction force of the pry bar, the battery box is brought out of the mounting groove, which can overcome a large friction force, thereby avoiding the battery box from getting stuck, and solving the problem of inconvenient disassembly of the existing power battery installation structure.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The embodiment of the power battery installation structure of the present invention is as follows Figures 1 to 3 As shown, the power battery mounting structure includes a mounting frame 3 for connecting to the vehicle frame and a battery box 1 for fixing the power battery. The mounting frame 3 is provided with a mounting groove for slidingly assembling the battery box 1. A locking groove 31 with an opening facing the middle of the mounting groove is provided at the opening position of the mounting groove. A locking rod 5 is hingedly mounted on the battery box 1. The locking rod 5 has a locking end 51 cantilevered into the locking groove 31 and an operating end extending away from the locking end 51. When locking, the locking end 51 is locked and limitedly matched with the upper groove wall 32 of the locking groove 31, and the operating end is connected to the battery box 1 by a screw 6. When unlocking, the operating end is separated from the battery box 1 and operated to move in the direction of the original battery box 1, and the locking end 51 is pressed and matched with the lower groove wall 33 of the locking groove 31 to pry the battery box 1.

[0020] In this embodiment, a roller 52 is rotatably mounted on the locking end 51 , and the roller 52 can reduce the friction between the locking rod 5 and the locking groove 31 , thereby preventing the friction from damaging the structures of the locking rod 5 and the locking groove 31 .

[0021] 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. The roller 52 is arranged in the limiting groove 53 and the two ends of its rotating shaft are correspondingly assembled in the two positioning holes. This structure can limit the two ends of the roller 52, and the support at both ends improves the structural strength of the support.

[0022] In order to facilitate the movement of the battery box 1 in the installation groove, in this embodiment, the groove wall of the installation groove is provided with balls 4 for rolling cooperation with the battery box tube. When installing or removing the battery box, the battery box rolls with the balls 4 on the groove wall of the installation groove, thereby reducing the friction between the battery box and the installation groove. In order to prevent the balls 4 from damaging the side wall of the battery box, the number of balls 4 is set to be multiple, so as to reduce the pressure when a single ball 4 contacts the side wall of the battery box.

[0023] In this embodiment, the side of the locking rod is a hollow structure, and a reinforcing rib 55 is provided in the hollow structure to increase the structural strength. The hollow structure can reduce the overall weight of the locking rod. A screw mounting hole 54 is provided at the rear end of the locking rod for mounting a screw. Specifically, the screw mounting hole 54 is a stepped hole, which is convenient for mounting the screw.

[0024] In this embodiment, the size of the upper groove wall 32 of the locking groove 31 is smaller than the size of the lower groove wall 33 so as to allow the locking end 51 of the locking rod to pass upward and downward.

[0025] 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 on the outside of the battery box body. The battery box body slides with the groove wall of the installation groove through the guide bar 2, and the guide bar acts as a reinforcing rib 55, thereby ensuring the overall structural strength of the battery box.

[0026] When the power battery mounting structure of the present invention is locked, the locking end is locked and limitedly matched with the upper groove wall 32 of the locking groove 31, and the operating end is connected to the battery box by a screw. When unlocking, the operating end is separated from the battery box and operated to move in the direction away from the battery box, and the locking end is pressed and matched with the lower groove wall 33 of the locking groove to pry the battery box. The locking connection between the battery box and the mounting frame 3 can be achieved through the locking rod. At the same time, during the disassembly process, the locking rod is pressed and matched with the lower groove wall 33 of the locking groove, so that the locking rod acts as a pry bar. Under the reaction force of the pry bar, the battery box is brought out of the mounting groove, which can overcome the large friction force, thereby avoiding the battery box from getting stuck, and solving the problem of inconvenient disassembly of the existing power battery mounting structure.

[0027] In other embodiments of the present invention, the locking end of the locking rod can also be set to an arc-shaped structure, thereby reducing the number of parts and reducing costs; the ball can also be set on the guide bar; the locking rod can also be set to an integrated solid structure; it is also possible not to set a guide bar and directly install and cooperate through the side wall of the battery box.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
