Description

Technical Field

[0001] This utility model belongs to the field of battery box bracket technology, specifically relating to a battery box bracket assembly. Background Technology

[0002] As the core load-bearing component of the battery system, the design of the battery box directly affects the safety, stability and overall performance of the battery pack. Traditional battery box bracket assembly designs often have problems such as many exposed parts, complex installation and large space occupation, which make it difficult to meet the requirements of modern equipment for high integration, lightweight and aesthetics.

[0003] According to CN221828055U, a battery box bracket assembly is disclosed, including a left support plate, a right support plate, a front support plate, and a rear support plate. The front support plate is fixed to the front of the left support plate by bolts, and the right support plate is fixed to one side of the front support plate by bolts. The rear support plate is fixed to the front of the left and right support plates. A second rubber pad is placed at the front of the rear support plate. A third rubber pad is fixed to the inner side of the left and right support plates. A first rubber pad is provided on the inner side of the front support plate. This utility model, by providing a third rubber pad inside the left and right support plates, a first rubber pad on the inner side of the front support plate, and a second rubber pad inside the rear support plate, and also having a rubber plate on the bottom plate, cushions the battery through the action of the first, second, and third rubber pads and the rubber plate, thereby preventing excessive impact between the battery and the bracket, which could lead to battery damage.

[0004] In the above technical solution, the clamping component forms a cross that covers the battery box. Although this installation method can fix the battery box, the clamping component increases the overall structure area around the battery box, resulting in more exposed parts, complicated installation, and large space occupation. Utility Model Content

[0005] The purpose of this invention is to provide a battery box bracket assembly to solve the problems of space utilization and bracket installation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A battery box bracket assembly includes a sheet metal bracket, which comprises a side sheet metal and a supporting sheet metal. The side sheet metal has a front end sheet metal on its left side, and the supporting sheet metal is on the right side of the side sheet metal. A tray is provided below the side sheet metal, and a bending plate is bent on one side of the tray. A groove is provided on one side of the side sheet metal near the supporting sheet metal, and a clamping mechanism is detachably installed on the groove.

[0008] Preferably, the supporting sheet metal surface has through holes and elliptical holes, and mounting screws are installed in the through holes and elliptical holes. The side sheet metal and the supporting sheet metal are symmetrically located on both sides of the front sheet metal. The supporting sheet metal is attached to the wall (here, the wall refers to the mounting surface used for attaching the supporting sheet metal, which can be any box or cabinet, etc.). The mounting screws are connected to the through holes or elliptical holes, that is, the sheet metal bracket is fixedly installed on the wall.

[0009] Preferably, the tray and the bending plate have several equidistant air holes on their surfaces, and irregular air grooves run through the side sheet metal surfaces. The design of the air holes and air grooves ensures uniform airflow; it helps to evenly dissipate the heat generated by the battery box during operation, avoiding localized overheating, thereby improving the battery box's working efficiency and lifespan.

[0010] Preferably, the clamping mechanism includes an L-bar, the short side of which is movably connected to a first pulley and a second pulley, and a gap equal to the thickness of the sheet metal is formed between the first pulley and the second pulley. The gap between the first pulley and the second pulley cooperates with the groove. The long side of the L-bar presses on the battery box, the first pulley rolls in contact with the surface of the bent plate, and the second pulley rolls in contact with the surface of the supporting sheet metal.

[0011] Preferably, the first and second pulleys can be replaced with rectangular blocks. These rectangular blocks are fixed and cannot rotate; the distance between the two rectangular blocks remains equal to the sheet metal thickness. The difference lies only in the type of friction: one uses rolling friction while the other uses sliding friction.

[0012] Preferably, the long side of the L-bar has a cross-cut. The cross-cut creates a flat surface below the long side of the L-bar, which directly contacts the top of the battery box. This flat surface provides a stable support for the battery box, ensuring its fixed position within the device and preventing shaking or displacement. Simultaneously, a rubber pad is attached to the surface of the cross-cut; this rubber pad acts as a buffer layer between the cross-cut and the battery box contact surface, preventing scratches, wear, or damage to the battery box surface.

[0013] Preferably, a mating block is installed above the short side of the L-rod, and a concentric groove matching the short side of the L-rod is provided below the mating block. A threaded groove and a second threaded hole are opened on the surface of the mating block, wherein the second threaded hole corresponds to the concentric groove. A hole that concentrically matches the second threaded hole is passed through the short side of the L-rod, and a clamping bolt is fitted in the second threaded hole.

[0014] Preferably, one side of the front sheet metal surface has symmetrical extension blocks, the extension blocks have a first threaded hole, the long side of the L rod has a through hole that is concentric with the first threaded hole, and a clamping screw is fitted in the first threaded hole and the through hole.

[0015] The technical solution of this utility model has the following beneficial effects:

[0016] 1. The L-shaped rod adopts a concealed installation method, mounted on a sheet metal bracket, avoiding the impact of exposed parts on the overall aesthetics. Concealed installation means the L-shaped rod does not occupy additional external space, contributing to the miniaturization and compact design of the equipment, improving space utilization, and reducing overall size and weight.

[0017] 2. By installing screws, the L-shaped rod and the sheet metal bracket can be fixed at the same time, reducing installation steps and time, improving installation efficiency, and reducing installation costs. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] Example 1:

[0027] refer to Figure 1 A battery box bracket assembly includes a sheet metal bracket, which includes a side sheet metal 101 and a support sheet metal 102. The side sheet metal 101 has a front sheet metal 103 on the left side and the support sheet metal 102 is on the right side of the side sheet metal 101.

[0028] The surface of the supporting sheet metal 102 has a through hole 104 and an elliptical hole 105, and a mounting screw 402 is installed in the through hole 104 and the elliptical hole 105.

[0029] In the above scheme, the side sheet metal 101 and the support sheet metal 102 are symmetrically located on both sides of the front sheet metal 103. The support sheet metal 102 is attached to the wall (the wall here refers to the mounting surface used for the support sheet metal 102, which can be any box or cabinet or other plane). The mounting screws 402 are connected to the opening 104 or the elliptical hole 105, that is, the sheet metal bracket is fixedly installed on the wall.

[0030] refer to Figures 1-4 A tray 201 is provided below the side sheet metal 101, and a bending plate 202 is bent on one side of the tray 201;

[0031] In the above solution, the surface of the tray 201 is used to support the battery box 60. The side sheet metal 101, the front sheet metal 103, and the bent plate 202 together form a rectangular structure. The inside of the rectangular structure is used to store the battery box 60, so as to avoid the problem of the battery box 60 falling off the sheet metal bracket.

[0032] Further reference Figure 3 and Figure 4 The tray 201 and the bent plate 202 have several equidistant air holes on their surfaces, and the side sheet metal 101 has irregular air channels running through its surface. The design of the air holes and air channels ensures uniform airflow; it helps the heat generated by the battery box 60 during operation to be evenly dissipated, avoiding localized overheating, thereby improving the working efficiency and lifespan of the battery box 60. At the same time, it reduces the amount of material used, thus reducing the overall weight.

[0033] refer to Figures 1-5 A groove 106 is provided on one side of the side sheet metal 101 near the supporting sheet metal 102, and a clamping mechanism is detachably installed on the groove 106.

[0034] The clamping mechanism includes an L-bar 30, the short side of which is movably connected to a first pulley 301 and a second pulley 302. A gap equal to the sheet metal thickness is formed between the first pulley 301 and the second pulley 302. The gap between the first pulley 301 and the second pulley 302 cooperates with the groove 106. The long side of the L-bar 30 presses on the battery box 60.

[0035] The first pulley 301 rolls in contact with the surface of the bending plate 202, and the second pulley 302 rolls in contact with the surface of the supporting sheet metal 102.

[0036] In the above scheme, the distance between the first pulley 301 and the second pulley 302 cooperates with the groove 106 to quickly achieve the initial positioning and installation of the L-rod 30. At the same time, the action of the first pulley 301 and the second pulley 302 can improve the sliding installation effect of the L-rod 30. The long side of the L-rod 30 presses on the battery box 60, which can achieve the purpose of pressing the battery box 60 and improving the stable installation effect of the battery box 60.

[0037] The specific installation plan involves simultaneously installing L-rods 30 on the grooves 106 of the two side sheet metal 101. This way, the long side of the L-rods 30 will press against the top of the battery box 60, and the two L-rods 30 can balance the positions of the two sides of the battery box 60.

[0038] It should be noted that the first pulley 301 and the second pulley 302 can be replaced with rectangular blocks. These rectangular blocks cannot rotate, which is a fixed structure. The distance between the two rectangular blocks is still equal to the thickness of the sheet metal. The only difference is that one is rolling friction and the other is sliding friction, which are alternative solutions.

[0039] Priority Solution Reference Figure 5 The long side of the L-bar 30 has a cross-cut 303. The cross-cut 303 creates a flat surface below the long side of the L-bar 30, which directly contacts the top of the battery box 60. This flat surface provides a stable support for the battery box 60, ensuring its fixed position within the device and preventing shaking or displacement. Simultaneously, a rubber pad is attached to the surface of the cross-cut 303; this rubber pad acts as a buffer layer between the cross-cut 303 and the battery box 60 contact surface, preventing scratches, wear, or damage to the surface of the battery box 60.

[0040] Further reference Figure 1 and Figure 5 A mating block 40 is installed above the short side of the L-rod 30. A concentric groove 403 that matches the short side of the L-rod 30 is provided below the mating block 40. A threaded groove 401 and a second threaded hole 404 are opened on the surface of the mating block 40. The second threaded hole 404 corresponds to the concentric groove 403. A hole that concentrically matches the second threaded hole 404 is passed through the short side of the L-rod 30. A clamping bolt 405 is fitted in the second threaded hole 404.

[0041] In a further embodiment, the mating block 40 is installed on the short side of the L-rod 30 via the concentric groove 403, and a clamping bolt 405 is installed in the second threaded hole 404 to fix the mating block 40. When the sheet metal bracket is fixed by the mounting screw 402, one mounting screw 402 is installed in the threaded groove 401 of the mating block 40, and the mounting screw 402 is installed on the wall through the elliptical hole 105. Here, the L-rod 30 and the sheet metal bracket are fixed at the same time by using the mounting screw 402, which reduces the installation steps and time, improves the installation efficiency, and reduces the installation cost. The design of the elliptical hole 105 allows for a certain installation error adjustment to ensure that the mounting screw 402 can pass through smoothly and be tightened.

[0042] Even if L-rod 30 needs to be disassembled separately, simply remove the mounting screw 402 on the mating block 40; the openings 104 at both ends are also fixed with mounting screw 402, which can improve the ease of disassembling the battery box 60 without affecting the stability of the sheet metal bracket.

[0043] Example 2:

[0044] refer to Figure 1 and Figure 4 The front sheet metal 103 has symmetrical extension blocks 107 on one side of its surface. The extension blocks 107 have a first threaded hole 108. The long side of the L rod 30 has a through hole 304 that is concentrically fitted with the first threaded hole 108. The first threaded hole 108 and the through hole 304 are fitted with a clamping screw 50.

[0045] In the above scheme, a clamping screw 50 is installed in the first threaded hole 108 and the through hole 304. The clamping screw 50 is tightened and fixed in the first threaded hole 108, thereby completing the fixation at both ends of the L rod 30 and further improving the clamping effect of the L rod 30.

[0046] In summary, the L-bar 30 adopts a concealed installation method, mounted on a sheet metal bracket, thus avoiding the impact of exposed components on the overall aesthetics. This concealed installation means the L-bar 30 does not occupy additional external space, contributing to the miniaturization and compact design of the equipment, improving space utilization, and reducing overall size and weight.

[0047] The specific implementation process of this utility model is as follows:

[0048] First, the sheet metal bracket is fixed to the wall by supporting the sheet metal 102 and connecting the mounting screws 402 at both ends of the opening 104. Then, the battery box 60 is placed on the surface of the tray 201. Next, L-rods 30 are installed simultaneously in the grooves 106 of the two side sheet metal 101. Then, the mating block 40 is installed on the short side of the L-rod 30 through the concentric groove 403, and at the same time, the clamping bolt 405 is installed in the second threaded hole 404 to fix the mating block 40. A mounting screw 402 is installed in the threaded groove 401 of the mating block 40, and the mounting screw 402 is installed on the wall through the elliptical hole 105. Here, the mounting screw 402 simultaneously fixes the L-rod 30 and the sheet metal bracket. Finally, a clamping screw 50 is installed in the first threaded hole 108 and the through hole 304. The clamping screw 50 is tightened and fixed in the first threaded hole 108 to complete the installation of the battery box 60 and the sheet metal bracket.
