Description

Technical Field

[0001] This utility model relates to the technical field of battery manufacturing, and in particular to a battery bracket housing. Background Technology

[0002] In today's energy storage and application fields, cylindrical lithium batteries are widely used in various electronic devices, electric vehicles, and energy storage systems due to their high energy density, good charge-discharge performance, and relatively stable chemical properties. To ensure the stability and safety of cylindrical lithium batteries during operation, and to achieve electrical connections and mechanical fixation between batteries, battery brackets have become an indispensable and crucial component. Currently, common cylindrical lithium battery brackets typically use two independent components, each fastened to one end of the battery. While this design provides a certain degree of support and fixation for the battery, multiple such brackets can be joined together to form a plate-like structure for application in larger-scale battery packs.

[0003] However, existing battery holders have the following shortcomings in practical use: when the battery pack is in a vibrating environment, frequently transported, or subjected to external impact, the batteries are prone to loosening and displacement within the holder because the holders at both ends of the battery pack are independent. This loosening, in turn, exerts a tensile force on the conductive plates welded to the ends of the holder. As a key component for connecting the battery to the external circuit, the conductive plates are highly susceptible to breakage if subjected to excessive tension. A broken conductive plate not only interrupts the electrical connection between the battery and the circuit, rendering the entire battery pack malfunction and affecting the performance of the equipment, but may also pose a serious safety hazard in severe cases. Therefore, this application proposes a battery holder housing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a battery holder shell that can prevent the conductive sheets from being pulled and broken due to loosening of the brackets at both ends of the battery, thereby improving the performance and safety of the device.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A battery holder housing, comprising:

[0007] A housing, comprising a top plate, a bottom plate, and two side plates, one end of each side plate being slidably connected to opposite sides of the bottom plate, and the ends of each side plate away from the bottom plate being slidably connected to opposite sides of the top plate; and

[0008] Multiple locking components are provided, each of which is slidably disposed at one of the four corners of the bottom plate and the top plate. Each locking component abuts against one of the four corners of the side plate, so that the locking components together engage the two side plates.

[0009] Optionally, the bottom plate has the same structure as the top plate.

[0010] Optionally, the bottom plate and the top plate are provided with sliding grooves on their opposite sides, and the two ends of the side plate are respectively provided with sliding rails. One side plate drives the two sliding rails to engage with the sliding grooves on the bottom plate and the top plate respectively.

[0011] Optionally, both the bottom plate and the top plate are provided with material placement grooves, and the two material placement grooves are close to each other.

[0012] Optionally, the base plate is further provided with a plurality of heat dissipation holes, each of which is distributed at intervals on the inner bottom wall of the material storage tank, and each of which is connected to the inner bottom wall of the material storage tank and the outer surface of the base plate.

[0013] Optionally, the base plate is further provided with a plurality of support blocks and a plurality of top connecting blocks. Each of the support blocks is distributed at intervals on the inner bottom wall of the material storage tank, and each of the support blocks abuts against the battery bracket. Each of the top connecting blocks is distributed at intervals on the inner bottom wall of the material storage tank, and each of the top connecting blocks abuts against the conductive sheet.

[0014] Optionally, the base plate is further provided with a plurality of raised blocks, and each of the raised blocks is distributed at intervals on the outer surface of the base plate.

[0015] Optionally, each of the heat dissipation holes, each of the support blocks, and each of the top connecting blocks are distributed alternately at intervals.

[0016] Optionally, the base plate may also have two wiring grooves, which are located on opposite sides of the base plate adjacent to the slide groove.

[0017] Optionally, locking grooves are provided at the four corners of the base plate, one end of each locking member slides in the corresponding locking groove, and the other end of each locking member abuts against the four corners of each side plate.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] The battery holder housing of this utility model is secured to the battery holders at both ends of the battery pack via a bottom plate and a top plate, respectively. Two side plates are also engaged with the opposing sides of the bottom and top plates, allowing the bottom and top plates to clamp the battery pack together. This prevents the battery from loosening under external impact and avoids pulling forces on the conductive sheets, which could lead to breakage. This improves the performance and safety of the battery pack. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0036] like Figures 1 to 9As shown, in one embodiment, a battery holder housing 1 includes a housing 10 and a plurality of locking members 20. The housing 10 includes a top plate 11, a bottom plate 12 and two side plates 13. One end of the two side plates 13 is slidably connected to the opposite sides of the bottom plate 12, and the ends of the two side plates 13 away from the bottom plate 12 are slidably connected to the opposite sides of the top plate 11. The plurality of locking members 20 are slidably disposed at the four corners of the bottom plate 12 and the top plate 11, and each locking member 20 abuts against the four corners of each side plate, so that each locking member 20 together engages the two side plates 13.

[0037] It should be noted that the base plate 12 and the top plate 11 have the same structure. A groove is formed on each of the two opposing sides of the base plate 12, extending from one end to the other, and both ends of the groove are connected to the end faces of the two ends of the base plate 12. Furthermore, a slide rail is formed on each end of one side of the side plate 13, and both ends of the slide rail are connected to the end faces of the two ends of the side plate. For example, both the groove and the slide rail are T-shaped. For ease of description, the two grooves on the base plate 12 are defined as the first groove 121 and the second groove, the two grooves on the top plate 11 are defined as the third groove 111 and the fourth groove, the two side plates 13 are defined as the left side plate and the right side plate, the two slide rails on the left side plate are defined as the first slide rail 131 and the second slide rail 132, and the two slide rails on the right side plate are defined as the third slide rail 133 and the fourth slide rail 134. Specifically, the first slide rail 131 is slidably engaged with the first slide groove 121, the second slide rail 132 is slidably engaged with the third slide groove 111, the third slide rail 133 is slidably engaged with the second slide groove, and the fourth slide rail 134 is slidably engaged with the fourth slide groove, so that the top plate 11, the bottom plate 12, and the two side plates 13 together form a frame with both ends connected. Thus, the bottom plate 12 and the top plate 11 are respectively fastened to the battery brackets 30 at both ends of the battery pack, and the two side plates 13 are respectively engaged with the opposite sides of the bottom plate 12 and the top plate 11, so that the bottom plate 12 and the top plate 11 together clamp the battery pack, preventing the battery brackets 30 from being loosened by external impacts, and avoiding the pulling force on the conductive sheet 40, which could lead to breakage of the conductive sheet 40. This improves the performance and safety of the battery pack.

[0038] It should be noted that the four right angles of the base plate 12 are all chamfered, and the two ends of the two slides are respectively connected to the two adjacent chamfers. Several locking grooves 123 are respectively formed on the other two sides of the base plate 12 adjacent to the two slides, with each locking groove 123 located at one of the four corners of the base plate 12. For example, each locking groove 123 is T-shaped. Specifically, one end of each locking groove 123 is connected to a chamfer, and the other end of each locking groove 123 extends inward. In this way, a chamfer connects the end of a slide and the end of a locking groove 123, making the included angle between a slide and a locking groove 123 a right angle.

[0039] It should be noted that one end of each locking member 20 is slidably engaged within the locking groove 123, while the other end of each locking member 20 is located at the chamfered position to fill the chamfered area. Since both ends of the groove are connected to the two chamfers respectively, when one end of the locking member 20 fills the chamfered area, the slide rail slidably engaged within the groove cannot slide out from either end of the groove, thus causing one end of the slide rail to be fixedly mounted on one side of the base plate 12. In this way, when all locking members 20 are slidably engaged within their respective locking grooves 123, the two ends of the two sides are fixedly mounted on the opposing sides of the base plate 12 and the top plate 11, thereby forming a sturdy frame.

[0040] like Figures 2 to 3 , Figure 5 , Figure 7 As shown, in one embodiment, both the bottom plate 12 and the top plate 11 are provided with material placement grooves 124, and the two material placement grooves 124 are close to each other.

[0041] It should be noted that both the bottom plate 12 and the top plate 11 are provided with material placement slots 124. When the opposing sides of the bottom plate 12 and the top plate 11 are respectively engaged with the two side plates 13, the material placement slots 124 on the bottom plate 12 and the top plate 11 tend to be in a mutually interlocking state. Furthermore, the battery brackets 30 at both ends of the battery pack are respectively housed in the material placement slots 124 of the bottom plate 12 and the top plate 11. The bottom plate 12 and top plate 11 respectively wrap around the brackets at both ends of the battery pack, and the slide rails at both ends on the same side respectively engage with the slide grooves on the sides of the bottom plate 12 and top plate 11, so that the bottom plate 12 and top plate 11 cannot be separated. In this way, the two independent battery brackets 30 located at both ends of the battery pack can engage the battery along the axial direction of the battery, so as to prevent the two independent battery brackets 30 from being unable to separate when the battery pack is in a vibrating environment, frequently transported, or subjected to external impact force. This also prevents the brackets from exerting a pulling force on the conductive sheet 40 welded to the end of the battery, which could cause the conductive sheet 40 to be broken due to excessive pulling, or cause the welding point at the end of the battery to loosen.

[0042] like Figures 1 to 3 , Figure 5 , Figure 7 As shown, in one embodiment, the base plate 12 is also provided with a plurality of heat dissipation holes 125, each heat dissipation hole 125 being distributed at intervals on the inner bottom wall of the material storage tank 124, and each heat dissipation hole 125 being connected to the inner bottom wall of the material storage tank 124 and the outer surface of the base plate 12.

[0043] It should be noted that the base plate 12 is also provided with several support blocks 126 and several top contact blocks 127. The support blocks 126 are distributed at intervals on the inner bottom wall of the material storage tank 124. The upper surface of each support block 126 is higher than the inner bottom wall of the material storage tank 124, so that there is a gap between the upper surface of each support block 126 and the inner bottom wall of the material storage tank 124. Each support block 126 abuts against the end face of the battery bracket 30 away from the battery. This also creates a gap between the battery bracket 30 and the inner bottom wall of the material storage tank 124. Since each heat dissipation hole 125 is located on the inner bottom wall of the material storage tank 124 and each heat dissipation hole 125 is connected to the inner bottom wall of the material storage tank 124 and the outer surface of the base plate 12, the gap between the battery bracket 30 and the inner bottom wall of the material storage tank 124 can communicate with each heat dissipation hole 125. In this way, the heat generated when the battery pack is working can flow from the gap to each heat dissipation hole 125 and be discharged from each heat dissipation hole 125, thereby reducing the temperature of the battery pack during operation. Furthermore, the shape and size of each heat dissipation hole 125 are different, so that each heat dissipation hole 125 can be distributed between each support block 126 and each top contact block 127 on the inner bottom wall of the material tray 124, thereby increasing the heat dissipation performance.

[0044] It should be noted that the top contact blocks 127 are spaced apart on the inner bottom wall of the material placement groove 124, and each top contact block 127 abuts against the conductive sheet 40. The height of each top contact block 127 is greater than that of each support block 126. When the battery pack moves any one of the battery brackets 30 into the material placement groove 124 on the base plate 12, and the end face of the battery bracket 30 abuts against the upper surface of each support block 126, the top contact blocks 127 can abut against the welding position of the conductive sheet 40 and the battery. In this way, the conductive sheet 40 and the electrode at the end of the battery are pressed tightly together, thereby ensuring the stability of the welding between each battery and the conductive sheet 40.

[0045] like Figures 1 to 3 , Figure 5 As shown, in one embodiment, the base plate 12 is further provided with a plurality of shims 128, and each shim 128 is distributed at intervals on the outer surface of the base plate 12.

[0046] It should be noted that each shim 128 protrudes relative to the outer surface of the base plate 12, creating a height difference between each shim 128 and the outer surface of the base plate 12. Since each heat dissipation hole 125 connects to the inner bottom wall of the material storage tank 124 and the outer surface of the base plate 12, and the outer surface of the base plate 12 will abut against the workbench surface and the inner sidewall of the housing 10 during production, handling, or use, when each shim 128 abuts against the workbench surface and the inner sidewall of the housing 10, a gap is formed between the outer surface of the base plate 12 and the workbench surface and the inner sidewall of the housing 10. This prevents the end of each heat dissipation hole 125 away from the inner sidewall of the material storage tank 124 from being blocked, thus affecting the heat dissipation from the battery pack through the heat dissipation holes 125. Furthermore, the shims 128 are spaced apart on the outer surface of the base plate 12, allowing each shim 128 to be evenly stressed to support the base plate 12.

[0047] like Figures 1 to 3 , Figure 5 , Figure 7 As shown, in one embodiment, each heat dissipation hole 125, each support block 126 and each top contact block 127 are distributed alternately at intervals.

[0048] It should be noted that the heat dissipation holes 125, support blocks 126, and top contact blocks 127 are distributed at intervals and staggered to ensure that the support blocks 126 are evenly stressed to support the battery bracket 30. Each top contact block 127 abuts against the welding point of each battery. The heat dissipation holes 125 are evenly distributed on the inner bottom wall of the material storage tank 124 to ensure that the battery pack can dissipate heat evenly.

[0049] like Figures 1 to 3 , Figure 5 , Figure 7 As shown, in one embodiment, the base plate 12 is further provided with two wiring grooves 129, which are located on opposite sides of the base plate 12 adjacent to the slide groove.

[0050] It should be noted that wiring grooves 129 are respectively formed on the two opposing sides of the base plate 12 adjacent to the slide groove. One end of each wiring groove 129 is connected to one of the two sides of the base plate 12, and the other end of each wiring groove 129 is connected to the inner wall of the material placement groove 124. The depth of the two wiring grooves 129 is greater than the depth of the material placement groove 124. In this way, when the end face of the battery bracket 30 abuts against each support block 126, the conductive pieces 40 on the side of the battery bracket 30 away from the battery can be electrically connected to external equipment through the wiring grooves 129 to meet the usage requirements of the battery pack.

[0051] like Figure 9 As shown, in one embodiment, a protrusion is provided on the inner sidewall of the locking groove 123, and a groove is respectively provided on the two opposing sides of the locking member 20.

[0052] It should be noted that when one end of the locking member 20 slides into the locking groove 123, the locking member 20 will cause the grooves and protrusions on both sides to engage. In this way, the locking member 20 is prevented from sliding out of the locking groove 123 due to external vibration after sliding into the locking groove 123.

[0053] like Figures 1 to 3 , Figure 5 , Figure 8 As shown, in one embodiment, ventilation holes 135 are provided on the side plate 13, and each ventilation hole 135 is distributed at intervals on the side plate 13.

[0054] It should be noted that the two ends of each vent 135 face the two slide rails respectively, making each vent 135 perpendicular to the slide rails. Furthermore, several uprights 136 are also provided on the side plate 135, each upright 136 being perpendicular to the slide rails. When the two slide rails on the side plate 13 are respectively engaged with the sliding grooves on the bottom plate 12 and the top plate 11, the two ends of each upright 136 abut against the sides of the bottom plate 12 and the top plate 11 that are close to each other, thereby creating a supporting force between the bottom plate 12 and the top plate 11. For example, when the slide rails on the ends of the two side plates 13 furthest from the bottom plate 12 are engaged with the two sliding grooves on the top plate 11, the uprights 136 on the two side plates 13 can jointly support the top plate 11, preventing the top plate 11 from being squeezed against the battery pack and causing damage when subjected to external force.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
