Technical Field

[0001] The utility model belongs to the technical field of battery packs, and in particular relates to a self-tapping screw long slot structure of a bracket of a battery pack. Background Art

[0002] The battery cell holder is used to support and install the battery cell. The position for screwing the self-tapping screw into the battery cell holder is the tapping receiving position. When the self-tapping screw is screwed in in the prior art, the self-tapping screw relies on the thread to directly screw into the tapping receiving position, which produces a lot of waste and affects the structural strength of the holder, increases the mold cost, and shortens the mold life. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a long slot structure for self-tapping screws in a battery pack bracket. By reserving long slots for self-tapping screws to be screwed into the battery cell bracket, the mold cost is reduced and the mold life is extended without reducing the torque of the self-tapping screws.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a self-tapping screw long groove structure for a battery pack bracket, including a battery cell bracket of the battery pack, and a tapping receiving position for screwing the self-tapping screw into the frame of the battery cell bracket;

[0005] The striking receiving position is provided with a striking long groove corresponding to the self-tapping screw, and the bottom and one side end surface of the striking long groove are both in an open structure shape communicating with the notch.

[0006] Furthermore, the long groove is located on the top of the battery cell support.

[0007] Furthermore, the long tapping grooves are symmetrically distributed about the top center line of the battery cell bracket, forming a double self-tapping screw fastening point structure.

[0008] Furthermore, the punched long groove extends along the length structure direction of the battery cell support in the width direction, and extends along the width structure direction of the battery cell support in the length direction.

[0009] Furthermore, the punching receiving position is a protruding structural block formed by protruding on the top of the battery cell bracket, and the punching long groove is formed by slotting on the protruding structural block.

[0010] Furthermore, reinforcing ribs are symmetrically distributed on both length sides of the long groove.

[0011] Furthermore, the side end face opening of the long groove is located on the outside of the battery cell holder; the reinforcing rib is connected to the groove wall of the long groove to form a side groove; the side end face of the side groove located on the inner side surface of the battery cell holder is open, so that the direction of the side end face opening of the long groove is opposite to the direction of the side end face opening of the side groove.

[0012] Furthermore, structural reinforcement side blocks are provided on both sides of the bottom opening of the long groove.

[0013] Furthermore, the raised structural block, the structural reinforcement side block and the battery cell bracket are integrally formed.

[0014] Beneficial effects: The utility model reserves long grooves on the battery cell bracket for self-tapping screws to be screwed in, thereby reducing mold costs and extending mold life without reducing the torque of the self-tapping screws. In addition, the method of slotting for self-tapping screws to be screwed in can reduce the amount of waste generated, while also avoiding damage to the structural strength and stability of the battery cell bracket, and is suitable for large-scale promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is an enlarged schematic diagram of the structure of the location of the long groove from the inner side of the battery holder;

[0016] Figure 2 This is an enlarged schematic diagram of the structure where the long groove is located, viewed from the outside of the battery cell holder. DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] like Figure 1 and Figure 2 The figure shows a self-tapping screw slot structure for a battery pack bracket, comprising a battery cell bracket 1 for the battery pack. The bracket 1 has a tapping receiving area 2 for screwing in the self-tapping screws. The tapping receiving area 2 is provided with a tapping slot 3 corresponding to the self-tapping screws. The bottom and one side end surface of the tapping slot 3 are both open structures with connected slots. By preserving a slot for screwing in the self-tapping screws on the battery cell bracket 1, the utility model reduces mold costs and extends mold life without reducing the self-tapping screw torque. Furthermore, by creating slots for screwing in the self-tapping screws, waste generation is reduced while also preventing damage to the structural strength and stability of the battery cell bracket.

[0019] More specifically, the long tapping groove 3 is located at the top of the battery holder 1. In order to improve the reliability of the self-tapping screw connection, in the present invention, the long tapping groove 3 is symmetrically distributed about the top center line of the battery holder 1, forming a double self-tapping screw fastening point structure.

[0020] The punching receiving position 2 is a raised structural block formed by protruding from the top of the battery cell support 1, and the punching long groove 3 is formed by slotting on the raised structural block.

[0021] In order to ensure the structural connection stability between the raised structural block and the battery cell support, structural reinforcement is required. Therefore, reinforcing ribs 4 are symmetrically distributed on both length sides of the long groove 3 .

[0022] The side end face opening of the punched long groove 3 is located on the outside of the battery holder 1; the reinforcing rib 4 is connected to the groove wall of the punched long groove 3 to form a side groove 6; the side end face of the side groove 6 located on the inner side of the battery holder 1 is open, so that the side end face opening of the punched long groove 3 faces in the opposite direction to the side end face opening of the side groove 6. In the top view, the shape of the raised structural block is similar to a mountain shape. In the present utility model, the punched long groove 3 vertically penetrates the top of the battery holder 1, leaving a deeper space for the self-tapping screws, and is convenient for waste discharge in conjunction with the opening of the side end face of the punched long groove 3, while the side groove 6 only vertically penetrates the raised structural block and does not penetrate the top of the battery holder 1.

[0023] It is worth noting that structural reinforcement side blocks 5 are provided on both sides of the bottom opening of the long groove 3. The provision of the structural reinforcement side blocks 5 not only further increases the depth of the long groove 3, but also plays a role in structural reinforcement.

[0024] The raised structural block, the structural reinforcement side block 5 and the battery cell support 1 are integrally formed, thereby improving the overall structural strength and making it safer and more reliable.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
