Technical Field

[0001] The utility model relates to the technical field of battery packs, and particularly relates to a copper row fixing tooling. The utility model also relates to a battery pack provided with the above copper row fixing tooling. Background Art

[0002] With the booming development of the new energy vehicle industry, as the core component of electric vehicles, the performance and safety of battery packs have attracted more and more attention. Inside the battery pack, multiple battery cells form modules, and multiple modules are connected in series to form a power battery system. In this process, the copper row, as an important connecting component inside the battery pack, plays a crucial role.

[0003] Currently, the copper rows in the battery pack are generally fixed to the installation positions by bolts. Although this fixing method is simple and easy to operate, there are some potential problems in actual applications. Since the vehicle will be subjected to various vibrations and impacts during driving, over time, the bolt connections may become loose, resulting in the connection between the copper row and the installation position not being tight anymore, and then there is a risk of loosening, which will reduce the fixing effect of the copper row. Summary of the Utility Model

[0022] The arrangement of the first ratchet teeth can squeeze the fixing portion and limit the fixing portion to a certain extent, so that the fixing portion can only rotate in one direction, which is conducive to better fixing the copper busbar by the fixing portion.

[0023] The second ratchet tooth is provided so that the fixing part can only rotate in one direction. When it rotates in the reverse direction, it will be blocked by the first ratchet tooth, which helps to prevent the fixing part from falling out of the first through hole, thereby better fixing the copper busbar.

[0049] Embodiment 1

[0050] This embodiment relates to a copper bar fixing tooling, aiming to improve the fixing effect of the copper bar 1 at its installation position by optimizing its own structure.

[0051] In terms of the overall structure, the copper bar fixing tooling in this embodiment is used for fixing the copper bar 1 at the installation position. The fixing tooling includes: a receiving part 2, the receiving part 2 has an accommodating cavity s for receiving the end of the copper bar 1, and a first through hole 201 perpendicular to the insertion direction of the copper bar 1 is provided on the receiving part 2. A fixing part 3, the fixing part 3 can be operatively passed through the first through hole 201 and the basic matching hole of the copper bar 1 to form a constraint on the copper bar 1 in the accommodating cavity s. A limiting part 4, the limiting part 4 is arranged in the first through hole 201 to form a constraint on the fixing part 3 in the first through hole 201.

[0052] With the above settings, the copper bar 1 fixing mechanism in this embodiment can accommodate the end of the copper bar 1 through the provision of the receiving portion 2, restrain the copper bar 1 within the receiving cavity s through the provision of the fixing portion 3, and restrain the fixing portion 3 on the receiving portion 2 through the provision of the limiting portion 4. After the copper bar 1 is restrained in the receiving portion 2, the fixing portion 3 that restrains the copper bar 1 is also restrained within the receiving portion 2, which can prevent the copper bar 1 from loosening and disengaging from the receiving portion 2, enabling the copper bar 1 to be firmly fixed in the installation position, which is conducive to ensuring the fixing effect of the copper bar 1.

[0053] In this embodiment, in combination with Figures 1 to 3 as shown, the receiving portion 2 in this embodiment has a square block structure. The receiving portion 2 has a receiving cavity s, and the end of the copper bar 1 can be received within the receiving cavity s. The receiving portion 2 is also provided with a first through hole 201. When the end of the copper bar 1 is received within the receiving cavity s, the basic adaptation hole on the copper bar 1 is aligned with the first through hole 201, enabling the fixing portion 3 to pass through the first through hole 201 and the basic adaptation hole to impose a restraint on the copper bar 1.

[0054] In order to better receive the end of the copper bar 1, in combination with Figure 1 and Figure 4 as shown, the receiving portion 2 of the copper bar fixing tooling in this embodiment further includes a second through hole 202 perpendicular to the first through hole 201. The receiving cavity s is formed within the second through hole 202. The provision of the second through hole 202 enables the end of the copper bar 1 to pass through the receiving portion 2, which is conducive to the fixation of the end of the copper bar 1 within the receiving portion 2, and can improve the adaptability of the receiving portion 2, facilitating the reception of copper bars 1 of different sizes. The structure is simple and conducive to design and implementation.

[0055] Specifically, in order to facilitate the arrangement of the receiving portion 2 on the copper bar 1, the second through hole 202 of the receiving portion 2 in this embodiment is a square hole made of hard rubber. By forming the receiving portion 2 with hard rubber, the receiving portion 2 has a certain elasticity, enabling the receiving portion 2 to deform under a certain acting force, which is conducive to the arrangement of the copper bar 1 on the receiving portion 2.

[0056] In this embodiment, in combination with Figure 1 , Figure 2 , Figure 3 and Figure 5 as shown, the fixing portion 3 in this embodiment is used to impose a restraint on the copper bar 1 on the receiving portion 2. Through the provision of the fixing portion 3, the copper bar 1 can be restrained within the fixing portion 3 to improve the fixing effect on the copper bar 1.

[0057] To better fix the copper bar 1, the fixing part 3 of the copper bar fixing tooling in this embodiment includes a fixing bolt 301 screwed to the receiving part 2, and the bottom of the fixing bolt 301 passes through the first through hole 201 and extends outwards. By screwing the fixing bolt 301 onto the receiving part 2, it is beneficial to fix the copper bar 1 on the receiving part 2, and the bottom of the fixing bolt 301 extends outwards, which is beneficial to connect the copper bar 1 with other components in the battery pack.

[0058] Specifically, threads are provided on the outer wall of the fixing bolt 301. Correspondingly, threads are also provided on the inner wall of the first through hole 201. The setting of the threads restricts the axial direction of the fixing part 3 by the receiving part 2 and is not easily disengaged from the receiving part 2, and the threaded connection method facilitates the assembly of the fixing bolt 301 on the receiving part 2 and is easy to operate.

[0059] To better improve the fixing effect on the copper bar 1, combined with Figure 2 as shown, the fixing part 3 of the copper bar fixing tooling in this embodiment further includes a fixing nut 302 screwed to the bottom of the fixing bolt 301. Through the setting of the fixing nut 302, the fixing effect of the fixing part 3 on the copper bar 1 is better improved, and the setting of the fixing nut 302 can further prevent the loosening of the fixing bolt 301.

[0060] To facilitate the operation of the fixing part 3, combined with Figure 2 and Figure 5 as shown, an operation hole 303 is provided at the top of the fixing bolt 301 of the copper bar fixing tooling in this embodiment. The fixing bolt 301 can be rotated through the operation hole 303. Through the setting of the operation hole 303, the rotation operation of the fixing bolt 301 is facilitated, the structure is simple, and it is beneficial to the design and implementation.

[0061] Specifically, the shape of the operation hole 303 in this embodiment can be, for example, a hexagonal hole to fit a hexagonal wrench and facilitate the operation of the fixing bolt 301. Of course, the shape of the operation hole 303 can also be a slotted hole or a cross hole, etc., which can fit different tool operations, and only needs to meet the requirement that it can be operated by a tool.

[0062] To better restrict the fixing part 3, combined with Figures 3 to 5 as shown, the limiting part 4 of the copper bar fixing tooling in this embodiment includes a first ratchet tooth 401 extending inwards from the first through hole 201. The arrangement of the first ratchet tooth 401 can squeeze the fixing part 3 and constitute a certain limit to the fixing part 3, so that the fixing part 3 can only rotate in one direction, which is beneficial to better fixing the copper bar 1 by the fixing part 3.

[0063] Specifically, the first ratchet teeth 401 in this embodiment are all arranged in the same rotation direction. When the fixing part 3 is arranged on the receiving part 2, the end of the fixing part 3 abuts against the first ratchet tooth 401 to constitute a constraint on the fixing part 3.

[0064] More specifically, the first ratchet 401 is provided at the top of the first through hole 201. In order to better accommodate the end of the fixing bolt 301, the top of the first through hole 201 is of a sunken structure, and the first ratchet 401 is formed on the side wall of the sunken part. In this embodiment, the first ratchet 401 is integrally provided with the receiving part 2, so it is also made of hard rubber.

[0065] In order to better restrict the rotation of the fixing part 3, in combination with Figures 3 to 5 As shown, the limiting part 4 of the copper bar fixing tooling in this embodiment further includes a second ratchet 402 extending outward from the top of the fixing part 3. When the first ratchet 401 meshes with the second ratchet 402, the fixing part 3 is rotationally restricted and received in the first through hole 201. The setting of the second ratchet 402 enables the fixing part 3 to only rotate in one direction. When it rotates in the reverse direction, it will be blocked by the first ratchet 401, which helps to prevent the fixing part 3 from disengaging from the first through hole 201, thereby being able to better fix the copper bar 1.

[0066] Specifically, the second ratchet 402 and the first ratchet 401 are both arranged in the same rotation direction. When the fixing part 3 rotates in the same direction as the first ratchet 401 in the first through hole 201, since the first ratchet 401 is also made of hard rubber, it can rotate even if there is interference. When the fixing part 3 rotates in the reverse direction, due to the interference between the second ratchet 402 and the first ratchet 401, even if the first ratchet 401 is made of hard rubber, it is difficult to rotate in the reverse direction, which helps to improve the fixing effect of the copper bar 1 and prevent the copper bar 1 from becoming loose due to the loosening of the fixing part 3.

[0067] When the copper bar fixing tooling in this embodiment is in use, first, the receiving part 2 is sleeved on the end of the copper bar 1 so that the first through hole 201 is aligned with the basic mating hole of the copper bar 1. Then, the fixing bolt 301 is screwed into the first through hole 201 and the basic mating hole of the copper bar 1. The copper bar 1 and the receiving part 2 are placed together at the installation position of the copper bar 1, and the fixing nut 302 is screwed onto the protruding part of the fixing bolt 301, thus completing the installation and fixation of the copper bar 1.

[0068] The copper bar fixing tooling in this embodiment can cooperate with the receiving part 2 and the fixing part 3 to restrict the end of the copper bar 1, and the limiting part 4 restricts the fixing part 3, so that the copper bar 1 is not easily loosened after being fixed at the installation position, which helps to improve the fixing effect of the copper bar 1 at the installation position.

[0069] Embodiment Two

[0070] This embodiment relates to a battery pack, and the copper bar fixing tooling in Embodiment One is provided in this battery pack.

[0071] In this embodiment, by setting the copper bar fixing tooling in the first embodiment, the fixing effect of the copper bar 1 at the installation position can be improved, which is beneficial to preventing the loosening of the copper bar 1 during the use of the battery pack, thereby improving the use quality of the battery pack.

[0072] The above are only the 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 principle of the present invention shall be included in the protection scope of the present invention.
