Description

Technical Field

[0001] The utility model belongs to the technical field of battery packs, and in particular relates to a convex rib of a cell bracket of a battery pack. Background Art

[0002] The battery cells of the battery pack are positioned and fixed using two left and right cell holders, and the outer shell serves as a protective enclosure. After the cell holders and the shell are fixed, the lack of a guide structure at the connection causes uneven force on the cells under the action of external forces, resulting in damage and reduced anti-vibration protection performance. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a battery pack cell holder rib. The rib on the cell holder can play a guiding role. When an external force acts on the battery pack, the holder and the cell can be subjected to more uniform force, and the cell can be better clamped, thereby improving the ability to resist vibration.

[0004] Technical solution: In order to achieve the above-mentioned purpose, the utility model provides a battery pack cell holder rib, including a battery cell holder, wherein the battery cell holder is provided with a rib on the surface close to the battery pack shell, and the shell with a draft angle is installed in conjunction with the oblique wedge-shaped rib to clamp the battery cell of the battery pack.

[0005] Furthermore, the convex ribs on the battery cell support are integrally formed reinforcement ribs or welded reinforcement ribs.

[0006] Furthermore, the battery cell bracket includes a left battery cell bracket and a right battery cell bracket for clamping and fastening the battery cell, and the convex ribs are distributed on both the left battery cell bracket and the right battery cell bracket.

[0007] Furthermore, the convex ribs include left and right protective ribs provided on the left and right sides of the battery cell holder, front and rear protective ribs provided on the front and rear sides, and upper and lower protective ribs provided on the upper and lower sides.

[0008] Furthermore, a plurality of left and right protective ribs at the same height are distributed in the length direction of the battery cell support to form a left and right protective rib group.

[0009] Furthermore, the left and right protective rib groups are arranged in a plurality of groups in the height direction of the battery cell support.

[0010] Furthermore, the battery cell support is provided with a connecting piece slot, and in the height direction of the battery cell support, the left and right protective rib groups and the connecting piece slot are alternately distributed.

[0011] Furthermore, the battery cell holder is provided with a wire groove, and the left and right protective ribs and the wire groove are both in a state of protruding from the outer side surface of the battery cell holder.

[0012] Furthermore, the horizontal protruding dimensions of the left and right protective ribs are greater than the depth of the cable trough.

[0013] Beneficial effects: The convex ribs on the battery cell holder of the utility model can play a guiding role. When external force acts on the battery pack, the holder and the battery cell can be subjected to more uniform force. In addition, the draft angle of the shell is combined with the oblique wedge-shaped convex ribs to better clamp the battery cell, so that it can resist damage that may be caused by vibration, thereby greatly improving the safety of earthquake protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 This is a three-dimensional enlarged structural diagram of the position of one of the ribs on the battery cell bracket. DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, a battery pack cell holder rib includes a cell holder 1, with a rib 2 provided on the surface of the cell holder 1 near the battery pack's outer shell. The outer shell, which has a draft angle, cooperates with the wedge-shaped rib 2 to secure the battery pack's cells. The rib 2 on the cell holder 1 of the present invention can serve as a guide, ensuring that the holder and cells are subjected to more uniform force when external forces act on the battery pack. Furthermore, the draft angle of the outer shell cooperates with the wedge-shaped rib 2 to better secure the cells, preventing damage caused by vibration and significantly improving anti-vibration protection safety.

[0018] More specifically, the convex ribs 2 on the battery cell support 1 are integrally formed reinforcement ribs or welded reinforcement ribs.

[0019] In the battery pack of the present invention, the cell holder 1 includes a left cell holder and a right cell holder for clamping and clamping the cell. The ribs 2 are distributed on both the left cell holder and the right cell holder, thereby further improving the structural stability, ensuring the stability of the cell installation, and providing good anti-vibration protection safety.

[0020] The front, back, left, right, up and down in this utility model are based on the battery pack. Figure 1 As shown, the ribs 2 include left and right protective ribs 21 arranged on the left and right sides of the battery holder 1, front and rear protective ribs 22 on the front and rear sides, and upper and lower protective ribs 23 on the upper and lower sides. The ribs 2 are widely distributed on the battery holder 1, providing comprehensive anti-vibration protection.

[0021] Cell protection is most important on the left and right sides of the battery pack, as this direction is the axial direction of the battery and the cells must be securely secured. Therefore, the distribution of the left and right protective ribs 21 on the cell holder 1 should cover as many positions as possible. Therefore, in this embodiment, multiple left and right protective ribs 21 at the same height are distributed along the length of the cell holder 1, forming a left and right protective rib group. Several groups of these left and right protective rib groups are arranged along the height of the cell holder 1. The cell holder 1 has a connecting plate slot 3, and along the height of the cell holder 1, the left and right protective rib groups and the connecting plate slot 3 are alternately distributed.

[0022] The cell holder 1 has a wire trough 4. The left and right protective ribs 21 and the wire trough 4 protrude from the outer side of the cell holder 1. The wire trough 4 is used to bundle the sampling wires for the cells. To prevent the wire trough 4 from occupying space on the left and right protective ribs 21 and affecting the vibration protection safety of the battery pack, the horizontal protrusion of the left and right protective ribs 21 should be greater than the depth of the wire trough 4.

[0023] 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.
