DETAILED DESCRIPTION

[0047] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0049] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0050] It should be noted that the words first direction X, second direction Y and third direction Z that appear in the following description are only used to more clearly illustrate the specific structure of the present application in conjunction with the drawings, and the present application is not limited thereto. The first direction X, the second direction Y and the third direction Z have an angle between each other. Optionally, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0051] The embodiment of the present application is based on the existing low-frame battery pack structure, and proposes a roughly "E"-shaped bracket structure, which can effectively clamp and fix the flatly arranged connectors or the stacked connectors. At the same time, the bracket structure provided by the embodiment of the present application has the advantages of simple and compact structure, simple processing and assembly process, and after being installed in the battery pack, when the side column of the battery pack shell is deformed, it can be deformed accordingly, and will not affect the side column of the battery pack shell.

[0052] like Figures 1 to 4 As shown, an embodiment of the present application provides a support structure 100, wherein the support structure 100 includes a base 1, and at least two clamping parts 2 are provided on one side of the base 1 along a first direction X, and the clamping parts 2 are arranged at intervals along a second direction Y, and a clamping space 22 is formed between two adjacent clamping parts 2 for the connector 230 to be inserted.

[0053] Along the first direction X, a limiting portion 3 is provided at the end of the clamping portion 2 away from the base 1. Along the second direction Y, at least a portion of the limiting portion 3 protrudes from a side surface of the clamping portion 2 facing the adjacent clamping portion 2. When the connecting member 230 is set, the connecting member 230 is located between the base 1 and the limiting portion 3. The limiting portion 3 can block the movement of the connecting member 230 along the first direction X, thereby effectively preventing the connecting member 230 from escaping from the clamping space 22.

[0054] When the connecting member 230 is arranged in the clamping space 22, the two side surfaces of the connecting member 230 along the second direction Y are in contact with the two clamping parts 2, and the connecting member 230 is limited and fixed along the second direction Y by the two clamping parts 2; and along the first direction X, the end of the clamping part 2 away from the base 1 can generate elastic deformation along the second direction Y to move away from each other. When the connecting member 230 needs to be adjusted or replaced, a force is applied to the clamping part 2 to make the ends of the two clamping parts 2 away from the base 1 move away from each other, so as to increase the distance between the two limiting parts 3, so that the limiting part 3 no longer hinders the movement of the connecting member 230 along the first direction X. At this time, the connecting member 230 can be smoothly taken out of the clamping space 22, which can effectively simplify the maintenance and replacement process of the connecting member 230; then the force applied to the clamping part 2 is removed, and the clamping part 2 returns to its original state under the action of its own elastic restoring force, so that the bracket structure 100 provided in the embodiment of the present application can be reused, which can effectively reduce the maintenance and replacement cost of the connecting member 230.

[0055] like Figures 1 to 4 As shown, the bracket structure 100 provided in the embodiment of the present application, wherein the limiting portion 3 is formed with a guide surface 32 and a limiting surface 31 connected to each other, and the limiting surface 31 is arranged opposite to the base 1 along the first direction X to limit and fix the connecting member 230 on both sides along the first direction X, and cooperate with the two clamping portions 2 to realize the limiting and fixation of the connecting member 230 along the first direction X and the second direction Y.

[0056] The guide surface 32 is located on the side of the limiting surface 31 away from the base 1 along the first direction X, and along the direction away from the base 1, the distance between the guide surface 32 and the clamping portion 2 gradually decreases, that is, along the direction from the base 1 to the clamping portion 2, the distance between the limiting surfaces 31 of the two relatively arranged limiting portions 3 provided on the two adjacent clamping portions 2 gradually increases, so as to guide and correct the connecting member 230 during the process of installing the connecting member 230 into the clamping space 22. During the process of installing the connecting member 230 into the clamping space 22, the distance between the two limiting portions 3 gradually increases, so that the ends of the two clamping portions 2 away from the base 1 are elastically deformed in the direction away from each other. After the connecting member 230 moves to between the limiting surface 31 and the base 1, the connecting member 230 no longer applies a force to the limiting portion 3. The two clamping portions 2 move in the direction of approaching each other under the action of their own elastic restoring force, and the distance between the two limiting portions 3 is reduced to cooperate with the base 1 to limit and fix the connecting member 230 along the first direction X.

[0057] like Figure 5 As shown, in the support structure 100 provided by the embodiment of the present application, an anti-slip member 4 is provided on the inner surface of the clamping space 22 to increase the friction between the connecting member 230 and the support structure 100 and prevent the connecting member 230 from moving relative to the support structure 100 when it is not necessary.

[0058] Optionally, the anti-slip member 4 may be an anti-slip strip, anti-slip convex particles or an anti-slip rubber layer made of rubber or silicone material, and the anti-slip member 4 may be bonded and fixed to the inner surface of the clamping space 22 .

[0059] like Figure 6 As shown, in the bracket structure 100 provided by the embodiment of the present application, an anti-dropout member 5 is provided on the surface of the clamping portion 2 facing the adjacent clamping portion 2, so as to increase the force that needs to be overcome when the connecting member 230 is released from the clamping space 22, and prevent the connecting member 230 from being released from the clamping space 22 when it is unnecessary.

[0060] Optionally, the anti-slip component 5 may be a barb made of rubber or silicone material, and the anti-slip component 5 is bonded and fixed to the opposite surfaces of two adjacent clamping parts 2 forming the clamping space 22 .

[0061] The anti-slip part 4 and the anti-slip part 5 can be provided at the same time or only one of them can be provided, and the present application is not limited thereto.

[0062] like Figure 5 and Figure 6 As shown, the bracket structure 100 provided by the embodiment of the present application, wherein the clamping space 22 forms an opening along the first direction X on the side away from the base 1, and the bracket structure 100 also includes a blocking member 6, which is detachably connected to at least two adjacent clamping parts 2, and a part of the blocking member 6 blocks the opening of the clamping space 22.

[0063] Optionally, the blocking member 6 is a pull rope made of a flexible material, and a connecting hole 21 is provided on the clamping part 2. The two ends of the pull rope are detachably connected to the connecting holes 21 of the two clamping parts 2, so that the middle part of the pull rope is blocked at the opening of the clamping space 22, and the connecting member 230 can be further limited. Even if the connecting member 230 escapes from the clamping space 22 in an unnecessary state, it will be kept near the opening of the clamping space 22 under the limiting action of the pull rope, so that the staff can adjust it easily.

[0064] Alternatively, if Figure 7 As shown, the support structure 100 provided in the embodiment of the present application, wherein the dimension L of the support structure 100 along the first direction X is 5mm to 100mm; the dimension H of the support structure 100 along the second direction Y is 5mm to 100mm; the dimension W of the support structure 100 along the third direction Z is 1mm to 100mm; the dimension L0 of the base 1 along the first direction X is 1mm to 100mm; along the first direction X, the distance L1 between the limiting surface 31 and the base 1 is 1mm to 100mm; along the second direction Y, the distance H1 between two adjacent clamping portions 2 is 5mm to 100mm.

[0065] When the support structure 100 meets the above size range, it can be used for various connectors 230 existing in the existing battery pack 200, such as a connecting bar or a connecting harness, etc. In practical applications, the above size can be flexibly adjusted according to the specific size of the connector 230.

[0066] Optionally, the support structure 100 provided in the embodiment of the present application is integrally injection-molded from a plastic material, and the optional material may be a material with good plasticity, such as polypropylene, polyamide 6 or polyamide 66.

[0067] like Figures 8 to 11 As shown, the embodiment of the present application further provides a battery pack 200 , wherein the battery pack 200 includes a housing 210 , a cooling component 220 , a support structure 100 and a connector 230 .

[0068] Along the first direction X, the shell 210 has a side wall. The shell 210 may include a top shell and a bottom shell. The side wall may be an integral body or may be formed by splicing a wall portion of the top shell and a wall portion of the bottom shell.

[0069] The cooling member 220 is disposed inside the housing 210 , and the cooling member 220 is spaced apart from the side wall along the first direction X. The cooling member 220 is used to cool the structural components inside the housing 210 to ensure that the battery pack 200 operates within a suitable temperature range.

[0070] The support structure 100 is disposed between the cooling member 220 and the side wall, and is used to fix the connecting member 230; optionally, the support structure 100 is adhesively fixed to a side surface of the cooling member 220 facing the side wall.

[0071] Optionally, the surface of one side of the base 1 of the support structure 100 facing away from the clamping portion 2 is flat, so as to ensure that it has a sufficient bonding area when bonding with the cooling component 220.

[0072] The connecting member 230 is disposed between the cooling component 220 and the side wall, and the connecting member 230 is clamped in the clamping space 22 of the support structure 100 .

[0073] That is, the gap formed between the cooling component 220 and the side wall is used to arrange the support structure 100 and the connecting member 230. The cooling component 220 not only provides an installation basis for the support structure 100, but also can cool the support structure 100 and the connecting member 230.

[0074] Optionally, along the first direction X, the shell 210 has two oppositely disposed side walls, a cooling component 220 is disposed on the inner side of each side wall, and a gap is formed between the two cooling components 220 and the side wall that is closer to each other for arranging the connector 230 .

[0075] An accommodating space is formed between the two cooling components 220; the battery pack 200 also includes a beam structure 250 and a battery cell module 240, which are arranged in the accommodating space. The battery cell module 240 is used to provide electrical energy, and a mounting portion 251 is provided on the beam structure 250 for realizing the overall mounting installation of the battery pack 200.

[0076] Alternatively, if Figure 8 As shown, in the battery pack 200 provided in the embodiment of the present application, the beam structure 250 includes a beam extending along the first direction X. When a plurality of beams are provided, the plurality of beams are spaced apart along the third direction Z.

[0077] Alternatively, the beam structure 250 includes a longitudinal beam extending along the third direction Z. When a plurality of transverse beams are provided, the plurality of transverse beams are arranged along the first direction X at intervals.

[0078] Alternatively, the beam structure 250 includes at least one transverse beam extending along the first direction X and at least one longitudinal beam extending along the second direction Y, and the transverse beam and the longitudinal beam are arranged crosswise.

[0079] The beam structure 250 can improve the structural strength of the battery pack 200 and provide a foundation for the mounting portion 251 .

[0080] The battery pack 200 provided in the embodiment of the present application is used to fix the bracket structure 100 used for the connector 230. By providing at least two clamping parts 2, the two clamping parts 2 and the base 1 are enclosed to form a clamping space 22 for the connector 230 to be placed. By providing a limiting part 3 at the end of the clamping part 2 away from the base 1, the connector 230 placed in the clamping space 22 can be limited to prevent the connector 230 from escaping from the clamping space 22. When the connector 230 needs to be replaced, a force can be applied to the clamping part 2 along the second direction Y so that the two clamping parts 2 are elastically deformed to move in directions away from each other. At this time, the distance between the two limiting parts 3 is increased, and the movement of the connector 230 along the first direction X is no longer hindered. The connector 230 can be smoothly removed from the clamping space 22. This can effectively simplify the process of maintaining and replacing the connector 230, and the bracket structure 100 provided in the embodiment of the present application can be reused, thereby effectively reducing the maintenance and replacement cost of the connector 230.

[0081] An embodiment of the present application also provides a vehicle, wherein the vehicle includes the support structure or battery pack as described above, and the battery pack is used to provide electrical energy.

[0082] The vehicle provided in the embodiment of the present application, in which the bracket structure used for fixing the connecting piece in its battery pack, is provided with at least two clamping parts, so that the two clamping parts and the base are enclosed to form a clamping space for the connecting piece to be placed therein, and by providing a limiting part at the end of the clamping part away from the base, the connecting piece placed in the clamping space can be limited to prevent the connecting piece from escaping from the clamping space, and when the connecting piece needs to be replaced, force can be applied to the clamping part along the second direction to cause the two clamping parts to undergo elastic deformation to move in directions away from each other, at this time, the distance between the two limiting parts is increased, and the movement of the connecting piece along the first direction is no longer hindered, and the connecting piece can be smoothly removed from the clamping space, which can effectively simplify the process of maintaining and replacing the connecting piece, and the bracket structure provided in the embodiment of the present application can be reused, thereby effectively reducing the cost of maintaining and replacing the connecting piece.
