TECHNICAL FIELD

[0001] The present utility model relates to the technical field of batteries, in particular to a housing and a battery pack. BACKGROUND OF THE INVENTION

[0002] The battery pack typically includes a baseplate assembly and a frame surrounding the baseplate assembly. In related technology, the baseplate assembly and frame are often connected by rivet nuts.

[0003] Since the base plate assembly must support the battery and bear most of the weight of the battery pack, ensuring that the rivet nut has sufficient load-bearing capacity requires careful consideration of the thickness of the supporting part of the rivet nut. However, if the thickness of the supporting part of the rivet nut is too large, it is likely to affect the space in the height direction of the battery pack. Matching the load-bearing capacity of the rivet nut with the space occupied by the rivet nut has become an urgent problem that must be solved. SUMMARY OF THE UTILITY MODEL

[0004] In view of the above, the present utility model provides a housing and a battery pack to solve the problem of matching the load-bearing capacity of the rivet nut with the space occupied by the rivet nut.

[0005] In the first aspect, the present utility model provides a housing comprising: a base plate assembly, a frame disposed on one side of the base plate assembly in a first direction, the frame having a lower frame wall in close contact with the base plate assembly, a rivet assembly penetrating successively through the base plate assembly and the lower frame wall in the first direction, the rivet assembly having a first projection and a second projection, the base plate assembly and the lower frame wall being fastened via the first projection and the second projection, and the second projection being located on the side of the lower frame wall facing away from the base plate assembly, wherein the thickness of the first projection is T1, the thickness of the second projection is T2, and the circumferential outer diameter of the second projection is R2, wherein 25.65 mm ≤ T1·T2·R2 ≤ 96.25 mm is satisfied.

[0006] Advantageous Effects: According to the housing of the present embodiment, by reasonably controlling the lower limit value of T1 T2 R2, the thickness T1 of the first protrusion, the thickness T2 of the second protrusion, and the lower limit value of the circumferential outer diameter R2 of the second protrusion can be comprehensively controlled, thereby ensuring that the load-bearing capacity of the rivet assembly can withstand the weight of the battery on the base plate assembly and preventing connection failure.In addition, by reasonably controlling the upper limit value of T1 T2 R2, the thickness T1 of the first protrusion, the thickness T2 of the second protrusion, and the upper limit value of the outer circumferential diameter R2 of the second protrusion can be comprehensively controlled, thereby avoiding the space in the height direction of the battery pack from being affected, ensuring that the difficulty of riveting remains within a reasonable range, and avoiding deformation of the base plate or the frame during the riveting process.

[0007] In the second aspect, the present utility model further provides a battery pack comprising a battery set and a housing as described above adapted to accommodate the battery set.

[0008] Since the battery pack has the casing as described above, it has the same effect as the casing, which is not repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The embodiments of the present utility model will now be described in connection with the Fig. 1 to 5 described.

[0016] According to an embodiment of the present utility model, in one aspect, a housing is arranged which comprises: a base plate arrangement, 2, a frame 1 arranged on one side of the base plate assembly 2 in a first direction, the frame 1 having a lower frame wall 11 which is in close contact with the base plate assembly 2, a rivet assembly 3 penetrating successively through the base plate assembly 2 and the lower frame wall 11 in the first direction, the rivet assembly 3 having a first projection 311 and a second projection 312, the base plate assembly 2 and the lower frame wall 11 being fastened via the first projection 311 and the second projection 312, and the second projection 312 being located on a side of the lower frame wall 11 facing away from the base plate assembly 2, wherein the thickness of the first protrusion 311 is T1, the thickness of the second protrusion 312 is T2, and the circumferential outer diameter of the second protrusion 312 is R2, satisfying 25.65 mm ≤ T1 T2 R2 ≤ 96.25 mm.

[0017] In the present embodiment, the plane in which the first projection 311 is located and the plane in which the second projection 312 is located both extend parallel to a second direction, wherein the first direction is not parallel to the second direction.

[0018] In some embodiments, the first direction is perpendicular to the second direction. Both the first direction and the second direction may be the Fig. 2. Specifically, in the present embodiment, the first direction may be a vertical direction, and the second direction may be a horizontal direction.

[0019] In the present embodiment, the rivet assembly 3 may, in particular, be a rivet. Furthermore, the rivet may be a blind rivet or a component consisting of a rivet nut and a rivet bolt that fit together, etc.

[0020] In some embodiments, the rivet assembly 3 comprises a rivet nut 31 and a rivet bolt 32 screwed to the rivet nut 31, wherein the first projection 311 is arranged on the rivet nut 31 and the second projection 312 is formed by a partial deformation of the rivet nut 31 and extends in the second direction.

[0021] In the embodiments, the main part of the rivet nut 31 may be in the form of a nut shell, the first projection 311 may be a flange edge formed on the nut shell, and the first projection 311 and the nut shell may be integrally formed. To enable insertion of the nut shell before the rivet is pulled, since the second projection 312 has not yet been formed, after the rivet nut 31 is sequentially passed through the base plate assembly 2 and the lower frame wall 11, the rivet nut 31 is continuously tightened so that the nut shell can be partially deformed, and the deformation region extends in the second direction to form the second projection 312.In this case, the base plate assembly 2 and the lower frame wall 11 are fixed via the first projection 311 and the second projection 312, and the second projection 312 is located on the side of the lower frame wall 11 facing away from the base plate assembly 2. And the first projection 311 may be located on the side of the base plate 22 facing away from the lower frame wall 11, and the first projection 311 is located between the lower protection plate 21 and the base plate 22.

[0022] When the base plate assembly 2 is connected to the bottom wall 11 of the frame by the rivet assembly 3, the first protrusion 311 of the rivet assembly 3 and the second protrusion 312 formed after riveting are used for the fastening connection. In this case, the base plate assembly 2 supports the battery and bears most of the weight of the battery pack. The force will eventually act on the rivet assembly 3, making the second protrusion 312, in particular, a force point. Therefore, the relevant parameters of the second protrusion 312 are directly related to the connection strength. By reasonably controlling the relevant parameters of the second protrusion 312, the connection strength can be ensured and connection failure can be avoided.

[0023] In the present embodiment, since the first protrusion 311 can be located on the side of the base plate 22 facing away from the bottom wall 11 of the frame, the pressing force between the first protrusion 311 and the base plate 22 when the rivet nut 31 is continuously tightened to partially deform the nut shell to form the second protrusion 312 is configured to ensure the smooth formation of the second protrusion 312. If the thickness T1 of the first protrusion 311 is too small, it is likely to deform due to force during the riveting process. If the thickness T1 of the first protrusion 311 is too large, it is likely to affect the space in the height direction of the battery pack. In addition, since the base plate assembly 2 supports the battery, a certain gravity force will also be applied to the first protrusion 311.

[0024] In the present embodiment, the second protrusion 312 is formed by partially deforming the nut shell, and the deformation range extends in the second direction; that is, the thickness T2 of the second protrusion 312 actually corresponds to the overlap of two layers of the wall thickness of the nut shell. If the thickness T2 of the second protrusion 312 is too small, it is likely that it cannot support the weight of the battery on the base plate assembly 2, causing connection failure. In this case, the circumferential outer diameter R2 of the second protrusion 312 should be increased to ensure the load-bearing capacity of the second protrusion 312. And if the thickness T2 of the second protrusion 312 is too large, it means that the wall thickness of the nut shell is large.Although the riveting force is improved, the riveting difficulty will also increase significantly; deformation of the base plate or frame is likely to be caused, and deformation of the first protrusion 311 is likely to be caused. In this case, the outer circumferential diameter R2 of the second protrusion 312 should be reduced to reduce the formation difficulty.

[0025] It is therefore necessary to adjust the size ratio between T1, T2 and R2 sensibly.

[0026] The housing according to the present embodiment can comprehensively control the thickness T1 of the first protrusion, the thickness T2 of the second protrusion, and the lower limit of the circumferential outer diameter R2 of the second protrusion by reasonably controlling the lower limit of T1 T2 R2, thereby ensuring the load-bearing capacity of the rivet assembly 3 and ensuring that the rivet assembly 3 can withstand the weight of the battery on the base plate assembly 2 to avoid connection failure.And by reasonably controlling the upper limit of T1 T2 R2, the thickness T1 of the first protrusion, the thickness T2 of the second protrusion, and the upper limit of the circumferential outer diameter R2 of the second protrusion can be comprehensively controlled to avoid affecting the space in the height direction of the battery pack, thereby ensuring that the difficulty of riveting remains within a reasonable range and avoiding deformation of the base plate or frame during the riveting process.

[0027] For example, the value of T1*T2*R2 in the present embodiment may be 25.65 mm or 28 mm or 35 mm or 42 mm or 48 mm or 51 mm or 55 mm or 59 mm or 63 mm or 67 mm or 70 mm or 75 mm or 80 mm or 96 mm or 96.25 mm, etc., or may be an interval range formed from any two of the above values.

[0028] In some embodiments, the thickness T1 of the first protrusion 311 satisfies: 1.5 mm ≤ T1 ≤ 2.5 mm and / or the thickness T2 of the second protrusion 312 satisfies 1.9 mm ≤ T2 ≤ 3.5 mm and / or the circumferential outer diameter R2 of the second protrusion 312 satisfies 9 mm ≤ R2 ≤ 11 mm.

[0029] In the present embodiment, the second protrusion 312 is specifically formed by partially deforming the nut sleeve, with the deformation region extending in the second direction. The cross-sectional shape formed by the second protrusion 312 parallel to the second direction may be circular. In this case, the contact area between the second protrusion 312 and the bottom wall 11 of the frame may be further known based on the outer circumferential diameter R2 of the second protrusion 312.

[0030] For example, in the present embodiment, the value of T1 may be 1.5 mm or 1.8 mm or 1.9 mm or 2 mm or 2.2 mm or 2.5 mm, etc., or may be an interval range formed from any two of the above values.

[0031] For example, in the present embodiment, the value of T2 may be 1.9 mm or 2 mm or 2.2 mm or 2.5 mm or 2.3 mm or 2.8 mm or 3 mm or 3.2 mm or 3.5 mm, etc., or may be an interval range formed from any two of the above values.

[0032] For example, in the present embodiment, the value of R2 may be 9 mm or 9.5 mm or 9.8 mm or 10 mm or 10.5 mm or 10.8 mm or 11 mm, etc., or may be an interval range formed from any two of the above values.

[0033] In some embodiments, as in Fig. 2, a first adhesive layer 23 is arranged between the frame 1 and the base plate assembly 2, wherein the first adhesive layer 23 is designed to bond the frame 1 and the base plate assembly 2 to one another, wherein 25.65 mm ≤ T1·T2·R2 ≤ 68.75 mm is satisfied.

[0034] In the present embodiment, a first adhesive layer 23 is arranged between the frame 1 and the base plate assembly 2, wherein the value of T2 1.9 mm ≤ T2 ≤ 2.5 mm is satisfied.

[0035] In the present embodiment, the first adhesive layer 23 may in particular be an adhesive layer.

[0036] When the first adhesive layer 23 is applied between the frame 1 and the base plate assembly 2, a certain bonding force is generated between the frame 1 and the base plate assembly 2 due to the viscosity of the adhesive. In this case, the thickness T2 of the second projection 312 can be reduced accordingly to meet the load-bearing capacity requirements, that is, the upper limit of T1 T2 R2 can be correspondingly smaller.

[0037] For example, the value of T1*T2*R2 in the present embodiment may be 25.65 mm or 28 mm or 35 mm or 42 mm or 48 mm or 51 mm or 55 mm or 59 mm or 63 mm or 67 mm or 68.75 mm, etc., or may be an interval range formed from any two of the above values.

[0038] In some embodiments, the base plate assembly 2, as shown in Fig. 2, a lower protective plate 21 and a base plate 22, wherein the base plate 22 is arranged in close contact with the lower wall 11 of the frame and the lower protective plate 21 is arranged on the side of the base plate 22 which is facing away from the frame 1.

[0039] The first projection 311 is located on the side of the base plate 22 facing away from the lower wall 11 of the frame, and the first projection 311 is located between the lower protective plate 21 and the base plate 22.

[0040] In the present embodiment, the base plate 22 may in particular be a support plate or a heat exchanger plate.

[0041] In the present embodiment, the lower protection plate 21 is the lowest plate structure of the case, which can prevent impact and protect the base plate 22 and the battery.

[0042] The base plate 22 is arranged in close contact with the bottom wall 11 of the frame. In particular, the base plate 22 can be arranged in close contact with the battery pack for heat exchange for the battery pack in the housing.

[0043] By arranging the first projection 311 on the side of the base plate 22 facing away from the lower wall 11 of the frame, and since the first projection 311 is located between the lower protective plate 21 and the base plate 22, the first projection 311 can be used to support the base plate 22.

[0044] Furthermore, in some embodiments, the rivet assembly 3 comprises a rivet nut 31 and a rivet bolt 32 screwed to the rivet nut 31, wherein the rivet bolt 32 is formed with a bolt support portion 321 and the bolt support portion 321 abuts the side of the lower protective plate 21 facing away from the base plate 22.

[0045] The bolt support portion 321 can support the lower protection plate 21.

[0046] In some embodiments, as in Fig. 2, a second adhesive layer 24 is arranged between the lower protective plate 21 and the base plate 22. The second adhesive layer 24 is designed to bond the lower protective plate 21 to the base plate 22, wherein 25.65 mm ≤ T1 T2 R2 ≤ 73.15 mm and 1.5 mm ≤ T1 ≤ 1.9 mm are satisfied.

[0047] In the present embodiment, the second adhesive layer 24 may be an adhesive layer.

[0048] When a second adhesive layer 24 is disposed between the lower protective plate 21 and the base plate 22, a certain bonding force is present between the two due to the adhesive force of the adhesive. In this case, the thickness T2 of the second protrusion 312 can be reduced accordingly to meet the load-bearing requirements, that is, the upper limit of T1 T2 R2 can be correspondingly smaller. In this case, the thickness T1 of the first protrusion 311 can also be reduced accordingly to meet the support requirements for the lower protective plate 21.

[0049] For example, the value of T1·T2·R2 in the present embodiment may be 25.65 mm or 28 mm or 35 mm or 42 mm or 48 mm or 51 mm or 55 mm or 59 mm or 63 mm or 67 mm or 70 mm or 73.15 mm, etc., or may be an interval range formed from any two of the above values.

[0050] In some embodiments, a first adhesive layer 23 is arranged between the frame 1 and the base plate assembly 2, wherein the first adhesive layer 23 is designed to glue the frame 1 to the base plate assembly 2, a second adhesive layer 24 is arranged between the lower protective plate 21 and the base plate 22, wherein the second adhesive layer 24 is designed to glue the lower protective plate 21 to the base plate 22, wherein 25.65 mm ≤ T1 T2 R2 ≤ 52.25 mm, and 1.5 mm ≤ T1 ≤ 1.9 mm, 1.9 mm ≤ T2 ≤ 2.5 mm are met.

[0051] When a first adhesive layer 23 is disposed between the frame 1 and the base plate assembly 2, a certain bonding force is generated between the two due to the viscosity of the adhesive. In this case, the thickness T2 of the second protrusion 312 can be reduced accordingly to meet the load-bearing requirements. When a second adhesive layer 24 is disposed between the lower guard plate 21 and the base plate assembly 22, a certain bonding force is generated between the two due to the viscosity of the adhesive. That is, the upper limit of T1 T2 R2 can be correspondingly smaller. In this case, the thickness T1 of the first protrusion 311 and the thickness T2 of the second protrusion 312 can also be reduced accordingly to meet the support requirements for the lower guard plate 21.

[0052] For example, the value of T1·T2·R2 in the present embodiment may be 25.65 mm or 28 mm or 35 mm or 42 mm or 48 mm or 51 mm or 52.25 mm, etc., or may be an interval range formed from any two of the above values.

[0053] For example, in the present embodiment, the value of T1 may be 1.5 mm or 1.8 mm or 1.9 mm, etc., or may be an interval range formed from any two of the above values.

[0054] For example, in the present embodiment, the value of T2 may be 1.9 mm or 2 mm or 2.2 mm or 2.5 mm, etc., or may be an interval range formed from any two of the above values.

[0057] A plurality of rivet assemblies 3 may be located along the extension path of the frame 1, wherein a plurality of rivet assemblies 3 may surround the edge of the base plate assembly 2 to achieve the connection between the base plate assembly 2 and the frame 1 by connecting and fitting multiple points.

[0058] When the distance L between two adjacent rivet assemblies 3 is small, after distributing the force of the rivet assemblies 3, the relevant parameters T1, T2, and R2 of the rivet assemblies 3 can be correspondingly smaller. And when the distance L between two adjacent rivet assemblies 3 is large, after distributing the force of the rivet assemblies 3, the relevant parameters T1, T2, and R2 of the rivet assemblies 3 must be correspondingly larger.

[0059] For example, in the present embodiment, the value of L may be 70 mm or 72 mm or 75 mm or 78 mm or 80 mm or 82 mm or 85 mm or 88 mm or 90 mm, etc., or may be an interval range formed from any two of the above values.
