[0056] With the continuous development of battery devices, the requirements for battery device energy density and safety are getting higher and higher. Battery devices include housings, battery cells and electrical components, such as wiring harnesses and copper busbars. In order to improve the energy density of battery devices and meet compact design requirements, wiring harnesses and copper busbars need to be arranged in order in the housing.

[0057] Generally, the wiring harness and the copper busbar are fixed by setting a bracket. There may be a variety of specifications of wiring harness and copper busbar in the battery device. However, the compatibility of the brackets currently used is relatively poor, resulting in the need to configure a variety of brackets of different specifications, which increases the production cost of the battery device.

[0058] Based on the above considerations, please refer to Figures 1 and 2. The embodiment of the present application provides a bracket 100 and a battery device, the battery device includes a battery cell, an electrical component and the above-mentioned bracket 100, the electrical component is electrically connected to the battery cell, and includes a wire harness 200 and a copper bus 300. The bracket 100 is used to fix the wire harness 200 and the copper bus 300. Specifically, the bracket 100 includes a first mounting mechanism 1 and a second mounting mechanism 2. The first mounting mechanism 1 has a first mounting space 10 with adjustable size, and the first mounting space 10 is used to accommodate and fix the wire harness 200. The second mounting mechanism 2 includes a connecting frame 21 and an adjusting member 22. The adjusting member 22 is arranged inside the connecting frame 21, and the second mounting space 20 is enclosed with the connecting frame 21. The second mounting space 20 is used to accommodate and fix the copper bus 300, and the adjusting member 22 can be deformed to adjust the size of the second mounting space 20.

[0059] The bracket 100 and the battery device proposed in the embodiment of the present application are provided with a first mounting mechanism 1 and a first mounting space 10 on the first mounting mechanism 1 to fix the wiring harness 200. Since the size of the first mounting space 10 is adjustable, it can be applicable to wiring harnesses 200 of various sizes. The copper busbar 300 is fixed by providing a second mounting mechanism 2 connected to the first mounting mechanism 1, and an adjusting member 22 is provided inside the connecting frame 21, so that the adjusting member 22 and the connecting frame 21 enclose a second mounting space 20, and the copper busbar 300 is fixed by the second mounting space 20, and the size of the second mounting space 20 is adjusted by the deformation of the adjusting member 22, so that it can be applicable to copper busbars 300 of various sizes.

[0060] In one embodiment, as shown in Fig. 2, one first mounting mechanism 1 is provided, and one wire harness 200 can be fixed at a time. In some other embodiments, two or more first mounting mechanisms 1 can be provided to fix two or more wire harnesses 200 at the same time.

[0061] In order to facilitate the placement or removal of the wire harness 200, please continue to refer to Figure 2. The first mounting mechanism 1 can be set as an elastic structure to adjust the size of the first mounting space 10 through elastic deformation. The first mounting mechanism 1 is provided with an opening 11, and the opening 11 is configured to allow the wire harness 200 to enter and exit the first mounting space 10. Optionally, the end of the first mounting mechanism 1 at the opening 11 is rounded to prevent scratches on the wire harness 200.

[0062] The opening 11 is provided to form a passage for taking in and putting out the wire harness 200. Compared with the first installation mechanism 1 of a closed structure, it is more convenient to place the wire harness 200 into the first installation space 10 or to take it out from the first installation space 10. Moreover, the opening 11 is provided to facilitate the deformation of the first installation mechanism 1, thereby making it easier to adjust the size of the first installation space 10.

[0063] The wire harness 200 is generally a cylindrical structure. In order to make the shape of the first installation space 10 match the shape of the wire harness 200, the first installation mechanism 1 is set to an arc shape, and the arc angle of the first installation mechanism 1 is greater than 180°. By setting the first installation mechanism 1 to an arc shape, the first installation space 10 matching the shape of the wire harness 200 is formed inside the arc, which is conducive to the first installation mechanism 1 holding the wire harness 200 tightly. By setting the arc angle to be greater than 180°, that is, the width of the opening 11 is smaller than the diameter of the wire harness 200, the wire harness 200 is prevented from escaping from the first installation space 10.

[0064] In order to facilitate the placement or removal of the copper busbar 300, the connection frame 21 is set to an openable and lockable structure. Specifically, as shown in Figure 2, the connection frame 21 includes a main frame 211 and a cover plate 212. The main frame 211 is provided with a through mounting groove 2110, and the cover plate 212 can be opened and closed to cover the notch of the mounting groove 2110. The adjustment member 22 is arranged in the mounting groove 2110, and can be arranged on the main frame 211 or on the cover plate 212. When it is necessary to take the copper busbar 300 from the second installation space 20, the cover plate 212 is opened, and the copper busbar 300 is taken out or put in from the notch; after the copper busbar 300 is placed in place, the cover plate 212 is closed, so that the cover plate 212, the connection frame 21 and the adjustment member 22 cooperate to clamp the copper busbar 300.

[0065] Specifically, the copper busbar 300 is generally a rectangular parallelepiped structure, and therefore, the mounting groove 2110 is generally set to be a rectangle. The size of the mounting groove 2110 is larger than the size of the copper busbar 300 to reserve installation space for the adjustment member 22.

[0066] In one embodiment, as shown in FIG2 , the left end of the cover plate 212 is flexibly connected to the main frame 211, and the right end of the cover plate 212 is detachably connected to the main frame 211. Thus, the cover plate 212 can be lifted from the right side and turned toward the end of the flexibly connected, thereby avoiding the access path of the copper busbar 300.

[0067] In one embodiment, the right end of the cover plate 212 is connected to the main frame 211 by snapping, and the snapping connection is relatively firm and quick to disassemble and assemble. Specifically, a snap slot is provided at the right end of the cover plate 212, and a snap convex is correspondingly provided on the main frame 211, and the snap convex can be snapped into the snap slot to achieve the snap connection between the cover plate 212 and the main frame 211. Of course, the snap convex can also be provided on the cover plate 212, and the snap slot can be correspondingly provided on the main frame 211, which can also achieve the snap connection between the cover plate 212 and the main frame 211.

[0068] In order to ensure the connection strength of one end of the cover plate 212 flexibly connected to the main frame 211, a clamping structure is further provided between the left end of the cover plate 212 and the main frame 211. Specifically, as shown in FIG2 , the cover plate 212 includes a cover plate body 2121 and a clamping protrusion 2122, the clamping protrusion 2122 is provided at one end of the cover plate 212 flexibly connected to the main frame 211, and a clamping groove 2113 is correspondingly provided on the main frame 211, and the clamping protrusion 2122 can be inserted into the clamping groove 2113. When the cover plate 212 is closed to the main frame 211, the clamping protrusion 2122 is first aligned with the clamping groove 2113, and then the cover plate body 2121 is pressed downward, so that the clamping protrusion 2122 is clamped into the clamping groove 2113 and the other end of the cover plate body 2121 is clamped to the main frame 211. Both ends of the cover plate 212 are snap-fitted with the main frame 211 to achieve a secure cover, thereby preventing the cover plate 212 from being separated from the main frame 211 and affecting the fixation of the copper busbar 300 .

[0069] In one embodiment, in order to ensure that the clamping protrusion 2122 is firmly connected to the clamping groove 2113, a limiting member is provided between the clamping protrusion 2122 and the main frame 211 to limit the clamping protrusion 2122 from being separated from the clamping groove 2113. The limiting member can be a hook or a pin, etc., and there is no limitation on the specific structural form of the limiting member, as long as the clamping protrusion 2122 can be limited in the clamping groove 2113.

[0070] In some other embodiments, an interference fit may be provided between the snap-fit ​​protrusion 2122 and the snap-fit ​​groove 2113 , so as to restrict the snap-fit ​​protrusion 2122 from being separated from the snap-fit ​​groove 2113 by the interference fit.

[0071] In order to fix the copper bars 300 of different thicknesses and widths, as shown in FIG2 , the adjusting member 22 includes a width adjusting member 221 and a thickness adjusting member 222, which are respectively arranged on two adjacent inner walls of the connection frame 21 and can deform toward the inner walls to which they are connected. When the width adjusting member 221 deforms toward the inner wall where it is located, the width of the second installation space 20 is deformed, so that the copper bars 300 of various widths can be fixed; when the thickness adjusting member 222 deforms toward the inner wall where it is located, the height of the second installation space 20 is deformed, so that the copper bars 300 of various thicknesses can be fixed.

[0072] In one embodiment, the thickness adjusting member 222 and the width adjusting member 221 are both connected to the cover plate 212. After the copper busbar 300 is placed in the main frame 211, during the process of closing the cover plate 212, the thickness adjusting member 222 and the width adjusting member 221 gradually approach the copper busbar 300, are squeezed and deformed, and clamp the copper busbar 300.

[0073] In order to further ensure that the copper busbar 300 is firmly installed, as shown in FIG2 , an anti-skid pattern 2111 is provided on the inner wall of the connection frame 21 opposite to the width adjustment member 221. The anti-skid pattern 2111 increases the friction between the copper busbar 300 and the connection frame 21, which helps to prevent the copper busbar 300 and the connection frame 21 from moving relative to each other.

[0074] Optionally, please continue to refer to FIG. 2 , in order to improve the structural strength of the main frame 211, a convex rib 2112 is provided on the inner wall of the connecting frame 21 opposite to the thickness adjusting member 222, and the convex rib 2112 is used to abut against the copper busbar 300. The convex rib 2112 is provided to help improve the structural strength of the main frame 211, thereby providing a more stable fixing effect on the copper busbar 300.

[0075] Specifically, the convex ribs 2112 are arranged on the bottom plate of the main frame 211 and contact the copper busbar 300. At least two convex ribs 2112 are arranged along the width direction of the copper busbar 300 to ensure a good supporting effect on the copper busbar 300.

[0076] In some other embodiments, the thickness adjusting member 222 and the width adjusting member 221 can also be connected to the main frame 211. In this case, the thickness adjusting member 222 is arranged on the bottom plate of the main frame 211, and the width adjusting member 221 is arranged on the side wall of the main frame 211. When the copper bar 300 is installed, the copper bar 300 is pressed against the width adjusting member 221, and the width adjusting member 221 will limit the width direction of the copper bar 300. The copper bar 300 is placed on the thickness adjusting member 222, and the cover plate 212 is closed to apply pressure to the copper bar 300, thereby further squeezing the thickness adjusting member 222 to deform, and then the copper bar 300 is clamped under the action of the thickness adjusting member 222 and the cover plate 212.

[0077] It is understandable that one of the thickness adjusting member 222 and the width adjusting member 221 can be set on the main frame 211, and the other can be set on the cover plate 212, so as to ensure that a second installation space 20 for accommodating the copper bus 300 is enclosed between the thickness adjusting member 222, the width adjusting member 221 and the connecting frame 21. The specific setting positions of the thickness adjusting member 222 and the width adjusting member 221 are not limited here.

[0078] In one embodiment, as shown in combination with FIG. 2 and FIG. 3 , the width adjustment member 221 and / or the thickness adjustment member 222 includes a first elastic piece 2221 and a connecting member 2222, wherein the first elastic piece 2221 is arranged in an arc shape, and the concave surface of the arc faces the second installation space 20. One end of the connecting member 2222 is connected to the convex surface of the first elastic piece 2221, and the other end of the connecting member 2222 is connected to the inner wall of the connecting frame 21. By providing the arc-shaped first elastic piece 2221, both ends of the first elastic piece 2221 can press against the copper bar 300, so that a more uniform pressing force can be applied to the copper bar 300.

[0079] Specifically, the thickness adjusting member 222 adopts the structure of the first spring piece 2221 and the connecting member 2222, and the connecting member 2222 is connected to the cover plate 212. Of course, the width adjusting member 221 can also adopt the structure of the first spring piece 2221 and the connecting member 2222, and the connecting member 2222 is connected to one side wall of the main frame 211, so that the first spring piece 2221 faces the other side wall of the main frame 211.

[0080] In one embodiment, the width adjustment member 221 and / or the thickness adjustment member 222 includes a second elastic piece 2211, one end of the second elastic piece 2211 is elastically connected to the inner wall of the connection frame 21, the other end of the second elastic piece 2211 extends toward the second installation space 20, and the second elastic piece 2211 is deformed toward the inner wall to which it is connected when pressed. By providing the second elastic piece 2211, the elastic deformation of the second elastic piece 2211 is utilized to adjust the size of the second installation space 20, the first elastic piece 2221 has a simple structure, and the space avoidance effect is better when squeezed.

[0081] Specifically, since the thickness of the copper bar 300 is relatively small, the contact area between the width adjusting member 221 and the side of the copper bar 300 is smaller than that of the thickness adjusting member 222. Therefore, the width adjusting member 221 can adopt the structure of the second spring piece 2211, one end of the second spring piece 2211 is connected to the cover plate 212, and the other end of the second spring piece 2211 is inclined to the bottom plate of the main frame 211.
