[0047] The following will be combined with the attached Figures 1 to 14 The technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0048] Please refer to Figures 1 to 14 , the bracket system 100 of the embodiment of the present utility model includes a base 20, a mounting frame 30, and a bracket 10. The mounting frame 30 includes a first frame 31 and a second frame 32. Along the length direction b of the mounting frame 30, the first frame 31 and the second frame 32 are oppositely arranged on the base 20. Cross beams 33 are connected between the four corners of the first frame 31 and the four corners of the second frame 32. The bracket 10 is arranged between the first frame 31 and the second frame 32; or, along the width direction c of the mounting frame 30, the bracket 10 is arranged on the first frame 31 and the second frame 32.

[0049] It can be understood that when the bracket 10 is disposed between the first frame 31 and the second frame 32, both sides of the bracket 10 are respectively connected to the first frame 31 and the second frame 32. When the battery pack 200 is installed on the bracket system 100, the battery pack 200 is supported by the bracket 10. When brackets 10 are disposed on both the first frame 31 and the second frame 32, the brackets 10 on the first frame 31 correspond to the brackets 10 on the second frame 32. The brackets 10 on the first frame 31 and the brackets 10 on the second frame 32 together form a support system. When the battery pack 200 is installed on the bracket system 100, the brackets 10 on the first frame 31 and the brackets 10 on the second frame 32 jointly support a battery pack 200.

[0050] Please refer to Figures 1 to 2 、 Figure 10 and Figure 13 In some embodiments, posts 34 are disposed on both the first frame 31 and the second frame 32. A limiting member 40 is detachably installed on the post 34, and the limiting member 40 is located above the bracket 10. By providing the limiting member 40, the limiting member 40 is located above the bracket 10, the limiting member 40 is L-shaped, and a guiding channel is formed between the bottom of the limiting member 40 and the first support surface 1111 of the bracket 10. When the battery pack 200 is pushed into the bracket 10, at least a part of the flange 201 of the battery pack 200 is located in the guiding channel, and the guiding channel is used to assist the pushing of the battery pack 200, effectively avoiding displacement of the battery pack 200 during the process of being pushed into the bracket 10.

[0051] It can be understood that the number of brackets 10 and limiting members 40 can be set according to the number of battery packs 200 actually to be installed.

[0052] In some embodiments, the bracket system 100 further includes a housing. The housing is disposed on the base 20, and the mounting frame 30 and the bracket 10 are both disposed inside the housing.

[0053] Please refer to Figures 1 to 14 The bracket 10 according to the embodiment of the present utility model includes a bracket body 11. The bracket body 11 includes a support plate 111 for supporting the battery pack 200. The support plate 111 has a first support surface 1111 for contacting the bottom of the battery pack 200. The support plate 111 has a drawing bead 112 protruding from the first support surface 1111, and the drawing bead 112 is located at the front end of the support plate 111.

[0054] Compared with the prior art, in the bracket 10 of the embodiment of the present utility model, through the arrangement of the bracket body 11, the bracket body 11 includes a support plate 111. The bracket body 11 supports the battery pack 200 through the support plate 111. The bottom of the battery pack 200 contacts the first support surface 1111 of the support plate 111. The support plate 111 has a draw bead 112 protruding from the first support surface 1111, and the draw bead 112 is located at the front end of the support plate 111. When the battery pack 200 is pushed into the bracket 10, that is, when the battery pack 200 is pushed from the front end of the support plate 111 to the rear end of the support plate 111, the draw bead 112 props up one end of the battery pack 200, reducing the contact area between the bottom of the battery pack 200 and the first support surface 1111, so that the frictional force received by the battery pack 200 during the pushing process is reduced, and thus the battery pack 200 is more easily pushed into the bracket 10. In addition, through the arrangement of the draw bead 112, the draw bead 112 can not only improve the self-rigidity of the bracket 10, but also enhance the structural strength of the bracket 10, thereby improving the impact resistance or drop resistance of the bracket 10.

[0055] It can be understood that, under the condition that the friction coefficient and the normal pressure remain unchanged, since the frictional force is proportional to the contact area, the design of the draw bead 112 reduces the frictional force received by the battery pack 200 during the pushing process, making it easier to be pushed into the bracket 10.

[0056] Please refer to Figure 4 and Figure 7 In some embodiments, along the thickness direction a of the support plate 111, the support plate 111 further has a second support surface 1112. The first support surface 1111 and the second support surface 1112 are oppositely arranged, and the draw bead 112 protrudes from the second support surface 1112 towards the first support surface 1111. Through the arrangement of the second support surface 1112, along the thickness direction a of the support plate 111, the first support surface 1111 and the second support surface 1112 are oppositely arranged on the support plate 111. Since the draw bead 112 protrudes from the second support surface 1112 towards the first support surface 1111, without using other materials, the draw bead 112 can improve the self-rigidity of the bracket 10 without increasing the weight of the bracket 10.

[0057] It can be understood that the thickness direction a of the support plate 111 is consistent with the height direction of the mounting frame 30.

[0058] Furthermore, by adopting the CAE topography optimization simulation method, the draw bead 112 can improve the self-rigidity of the bracket 10 without increasing the weight of the bracket 10.

[0059] Please refer to Figure 7, Further, the thickness t of the draw bead 112 is equal to the thickness of the support plate 111. Specifically, the thickness t of the draw bead 112 satisfies the relationship: 0 < t ≤ 4 mm. For example, the thickness t of the draw bead 112 is 0.5 mm, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.3 mm, 2.4 mm, 2.7 mm, 3 mm, 3.1 mm, 3.6 mm, 3.9 mm or 4 mm, but is not limited to the listed values, and other values within the numerical range are equally applicable.

[0060] Please refer to Figures 3 to 7 , In some embodiments, the draw bead 112 includes an upper end surface 1121, a first arc surface 1122 and a second arc surface 1123. The upper end surface 1121 is located above the first support surface 1111, and the upper end surface 1121 is parallel to the first support surface 1111. The first arc surface 1122 and the second arc surface 1123 are both arranged around the upper end surface 1121, and the upper end surface 1121, the first arc surface 1122, the second arc surface 1123 and the first support surface 1111 are smoothly connected in sequence. By the combined use of the upper end surface 1121, the first arc surface 1122 and the second arc surface 1123, the upper end surface 1121, the first arc surface 1122, the second arc surface 1123 and the first support surface 1111 are smoothly connected in sequence, effectively making the surface of the draw bead 112 smooth. Since the weight of the battery pack 200 remains unchanged, that is, the normal pressure on the bracket 10 remains unchanged, therefore, the friction coefficient between the battery pack 200 and the bracket 10 is reduced, so that the frictional force received by the battery pack 200 during the pushing process is reduced, and further the battery pack 200 is more easily pushed into the bracket 10.

[0061] Please refer to Figures 6 to 7 , In some embodiments, the grinding height of the draw bead 112 is T, which satisfies the relationship: where t is the thickness of the draw bead 112. By setting the grinding height T of the draw bead 112, the grinding height T of the draw bead 112 cannot be too large or too small. When the grinding height T of the draw bead 112 is too small, that is, when , the curvature of the first arc surface 1122 is small, making the smoothness of the surface of the draw bead 112 poor, resulting in a large frictional resistance between the battery pack 200 and the draw bead 112 when the battery pack 200 is pushed into the bracket 10, and further affecting the assembly efficiency of the battery pack 200. When the grinding height T of the draw bead 112 is too large, that is, when , the grinding height T of the draw bead 112 being too large easily leads to excessive grinding of the draw bead 112. Since the thickness of the bracket 10 is relatively thin, excessive grinding of the draw bead 112 easily damages the overall strength of the bracket 10, and further affects its support stability and impact resistance.

[0062] Therefore, the grinding height T of the draw bead 112 satisfies the relationship: When the structural strength of the bracket 10 can be effectively ensured, the surface smoothness of the draw bead 112 can be improved.

[0063] Furthermore, the grinding height T of the draw bead 112 is 0.1 - 0.25 mm. Specifically, the grinding height T of the draw bead 112 is 0.1 mm, 0.12 mm, 0.13 mm, 0.15 mm, 0.17 mm, 0.18 mm, 0.2 mm, 0.21 mm, 0.22 mm, 0.24 mm or 0.25 mm, but is not limited to the listed values, and other values within the numerical range are equally applicable.

[0064] Please refer to Figure 7 , furthermore, the distance H between the plane where the upper end surface 1121 is located and the first support surface 1111 satisfies the relationship: 0 < H ≤ 2 mm. If H > 2 mm, the height of the draw bead 112 protruding from the first support surface 1111 is relatively large, resulting in a relatively large frictional resistance between the battery pack 200 and the draw bead 112 when the battery pack 200 is pushed into the bracket 10, and the draw bead 112 is likely to damage the surface of the battery pack 200 and destroy the insulating layer on the surface of the battery pack 200. Therefore, making the distance H satisfy the relationship: 0 < H ≤ 2 mm can effectively ensure the structural strength of the bracket 10 and reduce the friction coefficient between the battery pack 200 and the bracket 10, so that the frictional force received by the battery pack 200 during the pushing process is reduced, and thus the battery pack 200 is more easily pushed into the bracket 10.

[0065] Specifically, the distance H between the plane where the upper end surface 1121 is located and the first support surface 1111 is 0.1 mm, 0.15 mm, 0.2 mm, 0.24 mm, 0.5 mm, 1 mm, 1.2 mm, 1.3 mm, 1.7 mm, 1.9 mm or 2 mm, but is not limited to the listed values, and other values within the numerical range are equally applicable.

[0066] Please refer to Figure 5 , in some embodiments, along the thickness direction a of the support plate 111, the orthographic projection of the draw bead 112 on the first support surface 1111 is rectangular, circular or elliptical.

[0067] Preferably, along the thickness direction a of the support plate 111, the orthographic projection of the draw bead 112 on the first support surface 1111 is elliptical.

[0068] It can be understood that the number of draw beads 112 can be set according to the actual length of the bracket 10 and the stiffness requirements of the bracket 10. When the number of draw beads 112 is multiple, the multiple draw beads 112 are arranged in a matrix on the support plate 111.

[0069] Please refer toFigures 3 to 5 , Figure 10 and Figure 12 , in some embodiments, the bracket body 11 further includes a mounting plate 113 and a front end plate 114. The mounting plate 113 is disposed on at least one side of the support plate 111, and the front end plate 114 is disposed at the front end of the support plate 111. Both the mounting plate 113 and the front end plate 114 are perpendicularly disposed with respect to the support plate 111. The bracket 10 further includes a fixing plate 12. One end of the fixing plate 12 is detachably connected to the front end plate 114, and the other end of the fixing plate 12 is for detachably connecting to the battery pack 200. By the combined use of the mounting plate 113, the front end plate 114 and the fixing plate 12, with the mounting plate 113 disposed on at least one side of the support plate 111, the bracket 10 can be mounted on the first frame 31 and the second frame 32 through the mounting plate 113. The front end plate 114 is disposed at the front end of the support plate 111 and is used to assist in the installation of the fixing plate 12. After the battery pack 200 is pushed into the bracket 10, it can be installed and fixed through the fixing plate 12, preventing the battery pack 200 from slipping.

[0070] Specifically, when the mounting plate 113 is disposed on one side of the support plate 111, brackets 10 are mounted on both the first frame 31 and the second frame 32, and the brackets 10 on the first frame 31 and the second frame 32 are correspondingly disposed. At this time, the brackets 10 on the first frame 31 and the second frame 32 jointly support a battery pack 200. When mounting plates 113 are disposed on both sides of the support plate 111, the bracket 10 is disposed between the first frame 31 and the second frame 32. The mounting plate 113 on one side of the support plate 111 is connected to the first frame 31, and the mounting plate 113 on the other side of the support plate 111 is connected to the second frame 32.

[0071] Further, in order to enhance the self-rigidity and structural strength of the mounting plate 113 and the front end plate 114, drawing beads 112 can also be provided on the mounting plate 113 and the front end plate 114.

[0072] It can be understood that the mounting plate 113 and the front end plate 114 are connected and perpendicular to each other. The mounting plate 113, the front end plate 114 and the support plate 111 can be an integrally formed structure, that is, the mounting plate 113, the front end plate 114 and the support plate 111 are one component. Of course, the mounting plate 113, the front end plate 114 and the support plate 111 can also be a split structure, that is, the mounting plate 113, the front end plate 114 and the support plate 111 are three separate components, and the three components can be connected by welding.

[0073] It can be understood that the bracket 10 can be mounted on the first frame 31 and the second frame 32 by bolts or by welding.

[0074] Please refer to Figure 7 and Figure 13 In some embodiments, at least three reinforcing members 16 are provided between the second supporting surface 1112 of the supporting plate 111 and the mounting plate 113. By providing the reinforcing members 16, the structural strength of the bracket 10 is effectively enhanced, and the supporting effect of the bracket 10 on the battery pack 200 is improved.

[0075] Please refer to Figures 3 to 4 、 Figure 8 and Figure 9 In some embodiments, a positioning member 115 for restricting the battery pack 200 is provided at the rear end of the supporting plate 111. By providing the positioning member 115, the positioning member 115 is provided at the rear end of the supporting plate 111. When the battery pack 200 is pushed into the bracket 10, the positioning member 115 is used to restrict the battery pack 200 to prevent the battery pack 200 from slipping.

[0076] It can be understood that the positioning member 115 and the supporting plate 111 are of an integrally formed structure, that is, the positioning member 115 and the supporting plate 111 are one component, or the positioning member 115 and the supporting plate 111 may also be a split structure, that is, the positioning member 115 and the supporting plate 111 are two separate components.

[0077] Please refer to Figures 3 to 4 、 Figure 8 、 Figures 10 to 11 Furthermore, the positioning member 115 includes a first connecting portion 1151 and an elastic pressing strip 1152. The elastic pressing strip 1152 is connected to the supporting plate 111 through the connecting portion, and a space for clamping the battery pack 200 is formed between the elastic pressing strip 1152 and the supporting plate 111. By the combined use of the first connecting portion 1151 and the elastic pressing strip 1152, the elastic pressing strip 1152 is connected to the rear end of the supporting plate 111 through the first connecting portion 1151, and the elastic pressing strip 1152 and the supporting plate 111 cooperate to clamp the flange 201 of the battery pack 200, effectively positioning the battery pack 200 mounted on the bracket 10 and preventing the battery pack 200 from slipping.

[0078] Or, please refer to Figure 4 、 Figure 9 and Figures 13 to 14, the positioning member 115 includes a second connecting portion 1153 and an engaging portion 1154. The engaging portion 1154 is connected to the support plate 111 through the second connecting portion 1153. The engaging portion 1154 is used for clamping with the battery pack 200. Through the combined use of the second connecting portion 1153 and the engaging portion 1154, the engaging portion 1154 is connected to the support plate 111 through the second connecting portion 1153. When the battery pack 200 is installed on the bracket 10, the engaging portion 1154 is clamped with the flange 201 of the battery pack 200, effectively positioning the battery pack 200 on the bracket 10 and preventing the battery pack 200 from slipping.

[0079] Specifically, the engaging portion 1154 can be a protrusion or a groove. When the engaging portion 1154 is a protrusion, a groove for clamping with the protrusion is provided on the flange 201 of the battery; when the engaging portion 1154 is a groove, a protrusion for clamping with the groove is provided on the flange 201 of the battery.
