They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0029] The embodiment of the present application provides a copper busbar fixing bracket, which can fix two copper busbars at the same time, saving installation space and the number of copper busbar brackets, saving costs, and creating an effective partition between the two copper busbars to prevent direct contact and friction between the insulation layers of the two copper busbars.

[0030] The following is a detailed description of a copper bar fixing bracket provided in this embodiment. Figure 1 , Figure 2 As shown, it includes: a base body 1 and a snap-on structure 2, the base body 1 is provided with at least two independent accommodating cavities 11, at least two accommodating cavities 11 are arranged side by side and can allow at least two copper bars 3 to pass through at the same time; the snap-on structure 2 is arranged on the base body 1 and can be detachably installed on the beam 4.

[0031] In this embodiment, at least two independent accommodating cavities 11 are provided on the base body 1, so that at least two copper bars 3 can be fixed at the same time, which can save installation space and the number of copper bar brackets and save costs. A snap-fit ​​structure 2 is provided at the bottom of the base body 1, and the base body 1 can be installed as a whole on the beam 4 through the snap-fit ​​structure 2 for easy use.

[0032] Please continue to refer to Figure 1 , Figure 2 As shown, in this embodiment, it should be noted that the base body 1 is arranged on the crossbeam 4 in the vertical direction, and the installation operation is performed from top to bottom, so that it can be quickly installed and fixed even in a narrow space. The two accommodating cavities 11 are arranged side by side in the horizontal direction, and the accommodating cavity 11 is set in a rectangular shape. The two copper bars 3 are arranged in parallel in the horizontal direction and pass through the corresponding accommodating cavities 11 respectively. Therefore, during the arrangement process, the copper bar 3 is selected to pass through the above-mentioned accommodating cavity 11 horizontally in a vertical state, and the two ends of the copper bar 3 extend from the two sides of the accommodating cavity 11 to be connected to the battery module respectively, so that the accommodating cavity 11 can be used to support and fix the copper bar 3, and the two copper bars 3 can be arranged in parallel, which can save installation space. It is still applicable to the situation where the installation space is narrow, and it is more applicable.

[0033] Please refer to Figure 1 , Figure 3 as well as Figure 4As shown, in some embodiments, an elastic gasket 111 is provided at the bottom of the accommodating cavity 11, and the elastic gasket 111 is used to support the bottom of the copper bar 3. One end of the elastic gasket 111 is connected to the bottom of the accommodating cavity 11, and the other end is arranged obliquely upward, and the free ends of the elastic gaskets 111 at the bottom of the two accommodating cavities 11 are arranged facing each other, thereby extending the elastic gasket 111 through the bottom of the accommodating cavity 11 to support the bottom of the copper bar 3, and the elastic gasket 111 has an elastic rebound design, and the elastic gasket 111 is in direct contact with the bottom of the copper bar 3, which can not only play the role of fixing and supporting the copper bar 3, but also offset the stress generated by the copper bar 3 when the vehicle vibrates in the vertical direction.

[0034] Please continue to refer to Figure 1 , Figure 3 as well as Figure 4 As shown, in this embodiment, it should also be noted that the top of the accommodating cavity 11 is opened, and a limiting protrusion 112 is provided at the position of the opening, and two adjacent limiting protrusions 112 respectively support the top of the copper busbar 3.

[0035] In some embodiments, the cross-section of the upper part of the base body 1 along the vertical direction is in the shape of a "mountain". The "mountain"-shaped cross-section 113 is designed to isolate two accommodating cavities 11 for simultaneously fixing two copper bars 3, and to create an effective partition between the two copper bars 3 to prevent direct contact and friction between the insulation layers of the two copper bars; the base body 1 is designed with three limiting protrusions 112 on the top of the two accommodating cavities 11, and the limiting protrusions 112 are arranged above the copper bar 3, which can effectively fix the copper bar 3 and prevent the copper bar 3 from popping out of the accommodating cavity 11 when the vehicle vibrates in the vertical direction.

[0036] In some embodiments, two inverted triangular openings are formed between two adjacent limiting protrusions 112, and the two inverted triangular openings are respectively inserted into the two copper bars 3. When the three limiting protrusions 112 are designed, two inverted triangular openings are formed to facilitate the insertion of the copper bar 3 into the accommodating cavity 11. Thus, the "mountain"-shaped cross section 113, the two elastic gaskets 111 and the three limiting protrusions 112 on the top of the base body 1 together constitute two independent accommodating cavities 11, and the two accommodating cavities 11 can accommodate two copper bars 3 passing through at the same time, and the two copper bars 3 are arranged in parallel, and an effective partition can be generated between the two copper bars 3.

[0037] Please refer to Figure 3 , Figure 4As shown, in this embodiment, it should also be noted that the base body 1 is also provided with a weight-reducing cavity 12, and the weight-reducing cavity 12 is located below the bottom of the accommodating cavity 11. A plurality of cross-connected reinforcing ribs 121 are connected in the weight-reducing cavity 12, and the reinforcing ribs 121 divide the weight-reducing cavity 12 into a plurality of weight-reducing holes 122. In this embodiment, by adjusting the height dimension design of the weight-reducing cavity 12, the elastic gasket 111 supporting the bottom of the copper bar 3 inside the accommodating cavity 11 can be adjusted to a suitable height, which can be adapted to different application occasions. At the same time, the weight-reducing cavity 12 is composed of four left-right symmetrical weight-reducing holes 122, which can reduce the overall weight of the copper bar fixing bracket, reduce the material consumption and save costs, and the weight-reducing holes 122 of the weight-reducing cavity 12 are connected to the base body 1 through reinforcing ribs 121, and the reinforcing ribs 121 can increase the overall strength of the copper bar fixing bracket and enhance the overall anti-vibration effect of the copper bar fixing bracket.

[0038] Please refer to Figure 1 , Figure 2 as well as Figure 5 As shown, in the present embodiment, it is also necessary to explain that an elastic buckle 5 capable of abutting against the top of the cross beam 4 is provided at the bottom of the base body 1, and the snap-on structure 2 is located below the elastic buckle 5, and the elastic buckle 5 is arranged as an eight-shaped structure protruding away from the base body 1; by setting the elastic buckle 5 to the above-mentioned eight-shaped structure, when the base body 1 is installed on the cross beam 4, the elastic buckle 5 is squeezed to provide a biasing force toward the cross beam 4, and the elastic buckle 5 can also absorb the tolerance in the installation and matching process, so that the elastic buckle 5 is pressed against the cross beam 4 to prevent the copper busbar fixing bracket from shaking during use, and the copper busbar fixing bracket is effectively locked and fixed on the cross beam 4 through the direct contact between the elastic buckle 5 at the bottom of the base body 1 and the cross beam 4 to generate effective deformation and stress.

[0039] It should also be noted that, in the present embodiment, the buckle structure 2 is set as a U-shaped structure connected to the bottom of the base body 1, and the two sides of the U-shaped structure are set as a step structure that is progressively protruding from top to bottom along the height direction of the battery module. It can be understood that setting the buckle structure 2 as a U-shaped structure can facilitate the extrusion of the U-shaped structure from both sides, and the crossbeam 4 is provided with a mounting hole 41, so that the U-shaped structure can be released in the process of realizing the clamping between the step structure and the crossbeam 4. The copper bar fixing bracket is fixedly mounted on the crossbeam 4 through the two buckle structures 2 at the bottom, and the operation of directly fixing and installing by the buckle structure 2 is simple. At the same time, the use of two buckle structures 2 can increase the fixing reliability and effectively prevent the buckle structure 2 from rotating when it is installed on the crossbeam 4. Of course, it should also be noted that the middle part of the U-shaped structure can be connected to the elastic buckle 5 through components such as a connecting rod, and the step structure can be set with several layers as needed to adapt to the clamping of the buckle structure 2 with mounting holes 41 of different sizes, improve the versatility of the buckle structure 2, and facilitate the copper bar fixing bracket to be installed on the crossbeam 4 with mounting holes 41 of different sizes. Of course, the buckle structure 2 in this embodiment can adopt any suitable structural form, as long as the buckle structure 2 can be used to achieve a detachable connection with the crossbeam 4, such as a snap connection, etc., and no specific limitation is made in this embodiment.

[0040] In some embodiments, the copper busbar fixing bracket is entirely made of polypropylene plastic material, which has many advantages such as light weight, good toughness, good chemical resistance, and good insulation and voltage resistance performance.

[0041] In this embodiment, a copper bar fixing bracket installation structure is also provided. Figure 2 As shown, it includes a crossbeam 4 and a copper bar fixing bracket. The crossbeam 4 is provided with a mounting hole 41 , and the buckle structure 2 at the bottom of the copper bar fixing bracket is detachably snapped into the mounting hole 41 .

[0042] The implementation principle of this embodiment: the copper bar fixing bracket adopts an integrated structure, which can simplify the installation operation. At the same time, two independent accommodating cavities 11 are arranged on the base body 1, which can be used to fix two copper bars 3 at the same time. Therefore, one copper bar fixing bracket can fix up to two copper bars 3 at the same time, which can save installation space and the number of copper bar brackets and save costs. In addition, the two copper bars 3 can be arranged in parallel to save installation space. It is suitable for situations where the installation space is narrow and has stronger applicability.

[0043] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
