Description

Technical Field

[0001] This utility model relates to the field of battery transportation equipment, and more specifically, to a battery pack bracket and battery assembly. Background Technology

[0002] In existing technologies, battery pack brackets are matched with standard short battery packs, and the battery pack brackets have separate layer structures for multiple battery packs, thereby increasing the overall height of the battery and the bracket. Furthermore, as power demand increases, the height of the battery mounting frame also needs to be increased, leading to increased layout complexity and production costs for the battery pack brackets.

[0003] Therefore, the existing technology suffers from poor performance of battery pack brackets. Utility Model Content

[0004] The main objective of this invention is to provide a battery pack bracket and battery assembly to solve the problem of poor performance of existing battery pack brackets.

[0005] To achieve the above objectives, according to one aspect of the present invention, a battery pack bracket is provided, comprising: a mounting plate; and upright plates, wherein there are at least two upright plates, the two upright plates being erected on a set of opposite sides of the mounting plate, and a receiving space being provided between the two upright plates. The mounting plate has a clearance opening at least in the portion corresponding to the receiving space. The upright plates have a plurality of first mounting holes, and the other set of opposite sides of the mounting plate has a plurality of second mounting holes for fixing components corresponding to the periphery of the clearance opening. The fixing components are connected to the housing of the battery pack through the first mounting holes and / or the second mounting holes.

[0006] Furthermore, the upright plate has at least one weight-reducing hole, and each weight-reducing hole has at least one first mounting hole around its periphery.

[0007] Furthermore, the multiple first mounting holes are divided into multiple groups, and the multiple groups of first mounting holes are spaced apart along the height direction of the vertical plate.

[0008] Furthermore, the multiple first mounting holes are divided into multiple groups, and the multiple first mounting holes in the same group are spaced apart along the length direction of the vertical plate.

[0009] Furthermore, the battery pack bracket also includes reinforcing plates, with at least one reinforcing plate provided on each side of the two uprights that are far apart from each other.

[0010] Furthermore, multiple reinforcing plates are provided on the sides of the two uprights that are far apart from each other, and the multiple reinforcing plates are spaced apart along the length of the uprights.

[0011] According to another aspect of the present invention, a battery assembly is provided, including at least one housing having a first mating hole and a second mating hole, and the housing being detachably connected to the aforementioned battery pack bracket through the first mating hole and the second mating hole.

[0012] Furthermore, the first mating hole is provided on the circumferential sidewall of the housing; and / or a set of opposite sides at the top and a set of opposite sides at the bottom of the housing are provided with a mounting protrusion corresponding to the second mounting hole of the battery pack bracket mounting plate, the mounting protrusion having the second mounting hole.

[0013] Furthermore, there are multiple housings, which are detachably connected along the thickness direction. The mounting protrusion also has a third mounting hole, and two adjacent housings are connected through the third mounting hole.

[0014] Furthermore, a fourth mounting hole is provided on another set of opposite sides at the top and another set of opposite sides at the bottom of the housing. Two adjacent housings are connected through the fourth mounting hole. A connecting groove is provided on the circumferential sidewall of the housing corresponding to the fourth mounting hole at the top and / or the fourth mounting hole at the bottom of the housing, and the inner surface of the connecting groove communicates with the fourth mounting hole.

[0015] Applying the technical solution of this utility model, the battery pack bracket in this application includes: a mounting plate; upright plates, at least two upright plates, two upright plates erected on a set of opposite sides of the mounting plate, a receiving space between the two upright plates, the mounting plate having at least a clearance opening corresponding to the receiving space, the upright plates having a plurality of first mounting holes, and the other set of opposite sides of the mounting plate having a plurality of second mounting holes around the periphery of the clearance opening, the fixing components being connected to the housing of the battery pack through the first mounting holes and / or the second mounting holes.

[0016] When using the battery pack bracket of this application, since the mounting plate and the upright plate enclose a receiving space, the battery pack can be installed within this space. Furthermore, because the mounting plate has an opening corresponding to the receiving space, after the battery pack enters the receiving space, a portion of its structure can extend out through the opening, thereby reducing the overall height of the battery pack bracket and consequently reducing the overall height of the transport vehicle used to transport the battery pack, thus simplifying the layout of the battery pack bracket. Therefore, the battery pack bracket of this application effectively solves the problem of poor performance in existing battery pack brackets. Attached Figure Description

[0025] To address the issue of poor performance of existing battery pack brackets, this application provides a battery pack bracket and a battery assembly.

[0026] like Figure 1 and Figure 2 As shown, the battery pack bracket in this application includes: a mounting plate 10; and upright plates 20. There are at least two upright plates 20, which are erected on a set of opposite sides of the mounting plate 10. There is a receiving space 30 between the two upright plates 20. The mounting plate 10 has a clearance opening 40 at least in the portion corresponding to the receiving space 30. The upright plates 20 have a plurality of first mounting holes 21. The other set of opposite sides of the mounting plate 10 has a plurality of second mounting holes and fixing components 50 corresponding to the periphery of the clearance opening 40. The fixing components 50 are connected to the housing 70 of the battery pack through the first mounting holes 21 and / or the second mounting holes.

[0027] When using the battery pack bracket of this application, since the mounting plate 10 and the upright plate 20 enclose the receiving space 30, the receiving space 30 can provide installation space for the battery assembly. Furthermore, since the mounting plate 10 has a clearance opening 40 corresponding to the receiving space 30, after the battery assembly enters the receiving space 30, part of the battery assembly structure can extend out of the receiving space 30 through the clearance opening 40. This reduces the overall height of the battery pack bracket, and consequently reduces the overall height of the transport vehicle used to transport the battery assembly, thereby reducing the layout difficulty of the battery pack bracket. Therefore, the battery pack bracket of this application effectively solves the problem of poor performance of existing battery pack brackets.

[0028] Furthermore, in addition to transport vehicles, the battery pack bracket in this application can also be installed on other transport devices, such as ships. Moreover, in this application, a mounting frame can be provided on the transport device corresponding to the battery pack bracket, and the mounting frame can be provided with clearance space corresponding to the clearance opening 40, thereby ensuring that the battery components can enter the clearance space after extending out of the receiving space 30 through the clearance opening 40, thus making reasonable use of the internal space of the frame. This solves the problems of high space occupancy, high material cost, and inconvenient assembly and disassembly of existing battery pack brackets.

[0029] In this application, the fixing component 50 may include multiple bolts or screws, thereby ensuring that the bolts or screws can be connected to the battery assembly housing 70 after passing through the first mounting hole 21 or the second mounting hole. Furthermore, the mounting plate 10 and the upright plate can also be connected via the fixing component 50.

[0030] Furthermore, in one specific embodiment of this application, the thickness of both the mounting plate 10 and the upright plate 20 is greater than or equal to 20 mm.

[0031] Optionally, the upright plate 20 has at least one weight-reducing hole 22, and each weight-reducing hole 22 has at least one first mounting hole 21 around its periphery. This arrangement can effectively reduce the overall weight of the battery pack bracket, thereby reducing the difficulty of installing the battery pack bracket.

[0032] Optionally, the multiple first mounting holes 21 are divided into multiple groups, and the multiple groups of first mounting holes 21 are spaced apart along the height direction of the vertical plate 20. With this arrangement, when there are multiple housings 70 of the battery assembly, it can be ensured that multiple housings 70 can be connected to different groups of first mounting holes 21.

[0033] Optionally, multiple first mounting holes 21 in the same group are spaced apart along the length of the vertical plate 20. Of course, the arrangement of the first mounting holes 21 can be adapted to different design requirements in this application.

[0034] Optionally, the battery pack bracket further includes reinforcing plates 60, with at least one reinforcing plate 60 provided on each side of the two upright plates 20 that are far apart from each other. More optionally, multiple reinforcing plates 60 are provided on each side of the two upright plates 20 that are far apart from each other, and the multiple reinforcing plates 60 are spaced apart along the length of the upright plates 20. Furthermore, in this application, the thickness direction of the reinforcing plates 60 is perpendicular to the thickness direction of the upright plates 20. By providing reinforcing plates 60 in this application, the strength of the battery pack bracket can be effectively improved, thereby ensuring the performance stability of the battery pack bracket.

[0035] According to another aspect of the present invention, a battery assembly is provided, including at least one housing 70, the housing 70 having a first mating hole 71 and a second mating hole 72, and the housing 70 being detachably connected to the aforementioned battery pack bracket through the first mating hole 71 and the second mating hole 72.

[0036] Optionally, the first mating hole 71 is provided on the circumferential sidewall of the housing 70.

[0037] Optionally, a set of opposite sides at the top and a set of opposite sides at the bottom of the housing 70 are provided with mounting protrusions 73 corresponding to the second mounting holes of the mounting plate 10 of the battery pack bracket, and the mounting protrusions 73 have the second mounting holes.

[0038] Optionally, there are multiple housings 70, which are detachably connected along the thickness direction. The mounting protrusion 73 also has a third mounting hole, and two adjacent housings 70 are connected through the third mounting hole.

[0039] Of course, in this application, the second mounting hole and the third mounting hole can also be the same or the same hole. That is, among the different second mounting holes or third mounting holes, a portion of the second mounting holes or third mounting holes are used to connect two adjacent housings 70, and another portion of the second mounting holes or third mounting holes are used to connect the housing 70 to the mounting plate 10. Furthermore, the fixing component for connecting the housing 70 to the mounting plate 10 can also be used for connecting this housing 70 and adjacent housings 70.

[0040] In this application, since the housing 70 needs to be detachably connected to the mounting plate 10 via the mounting protrusion 73 and the second mounting hole and the fixing component 50, the overall length of the housing 70 including the mounting protrusion 73 may be greater than the length of the clearance opening 40. Therefore, the length of the housing 70 after removing the mounting protrusion 73 needs to be less than or equal to the length of the clearance opening 40 to ensure that the battery assembly can extend out of the clearance opening 40. Furthermore, when there are multiple housings 70, only one of the housings 70 has its top or bottom two mounting protrusions 73 connected to the mounting plate 10. Due to the presence of the mounting protrusion 73, during the process of allowing the battery assembly to pass through the clearance opening 40, the battery assembly can be tilted and adjusted sequentially in different directions, thereby allowing the mounting protrusion 73 to pass through the clearance opening 40. Optionally, a fourth mounting hole 74 is provided on another set of opposite sides at the top and another set of opposite sides at the bottom of the housing 70. Two adjacent housings 70 are connected through the fourth mounting hole 74. A connecting groove 75 is provided on the circumferential sidewall of the housing 70 corresponding to the fourth mounting hole 74 at the top and / or the fourth mounting hole 74 at the bottom of the housing 70, and the inner surface of the connecting groove 75 communicates with the fourth mounting hole 74.

[0041] In one specific embodiment of this application, a connecting groove 75 is provided on the circumferential sidewall of the housing 70 corresponding to the fourth mounting hole 74 at the bottom of the housing 70. After the fixing screw or bolt extends through this connecting groove 75 and extends out through this fourth mounting hole 74, it can enter the fourth mounting hole 74 at the top of the housing 70 located below this housing 70, thereby realizing the connection of the two housings 70.

[0042] Therefore, in this application, the stability of the connection between two adjacent housings 70 can be enhanced by providing the fourth mounting hole 74, and the assembly difficulty of the two housings 70 can be reduced by providing the connecting groove 75.

[0043] Furthermore, it is not difficult to see that when the battery assembly in this application has multiple housings 70, two adjacent housings 70 can be self-locked by using screws or bolts for connection, without the need to set up other structures for connecting two adjacent housings 70.

[0044] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0045] 1. Effectively solves the problem of poor performance of battery pack brackets in existing technologies;

[0046] 2. Simple structure and stable performance.

[0047] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0048] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0049] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
