Description

Technical Field

[0001] The utility model relates to the technical field of battery tooling, in particular to a battery module box-entering positioning tooling. Background Art

[0002] In the production process of the battery energy storage system, multiple battery modules need to be assembled into a box. During the assembly process, in order to ensure that the battery module is always located at the designed position and thus ensure the accuracy of the battery module entering the box, the operator often inserts a positioning block made of bakelite between the inner wall of the box and the battery module. For the purpose of positioning, the gap between the battery module and the box and the positioning block are often tight. After the battery module is put into the box, the positioning block is often stuck and difficult or even impossible to pull out. It is necessary to move the battery module again and increase the gap between the battery module and the box to pull out the positioning block. On the one hand, it will destroy the accuracy of the battery module entering the box, and on the other hand, it will also reduce the efficiency of the assembly operation. Utility Model Content

[0003] The utility model aims to solve the technical problem that after the existing bakelite positioning block is put into the box, the battery module needs to be moved before it can be pulled out, which leads to the destruction of the box insertion accuracy and the reduction of the assembly work efficiency, and provides a battery module box insertion positioning tool.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A battery module box positioning tool, comprising:

[0006] A first positioning block, the first positioning block having a first contact surface, the first contact surface being used to abut against the inner wall of the box;

[0007] A second positioning block, the second positioning block is slidably connected to the first positioning block, and the second positioning block has a second contact surface at one end away from the first positioning block, and the second contact surface is used to abut against the battery module;

[0008] The elastic element has two ends respectively abutting against the first positioning block and the second positioning block, and the elastic element is used to drive the first positioning block and the second positioning block to move away from each other.

[0009] The specific structural forms of the sliding connection include but are not limited to hole-shaft clearance fit, slide rail and slider mechanism, and slide rail and roller mechanism; the specific structural forms of the elastic element include but are not limited to rubber blocks, disc springs, and leaf springs.

[0010] The battery module box positioning tool of the present solution comprises a first positioning block and a second positioning block which are slidably connected, and an elastic element is arranged between the first positioning block and the second positioning block; when performing the box placement operation, the first positioning block and the second positioning block are squeezed to compress the elastic element, thereby reducing the distance between the first contact surface and the second contact surface until it is smaller than the distance between the battery module and the box body, and the battery module box positioning tool of the present solution can be easily placed between the battery module and the box body.

[0011] Then, the first positioning block and the second positioning block are loosened to expand the elastic element, and the distance between the first contact surface and the second contact surface will automatically increase until the first contact surface and the second contact surface respectively abut against the inner wall of the box and the battery module, thereby achieving reliable positioning of the battery module relative to the box.

[0012] After the boxing operation is completed, the first positioning block and the second positioning block are squeezed again to compress the elastic element, thereby reducing the distance between the first contact surface and the second contact surface until it is smaller than the distance between the battery module and the box body, and the battery module boxing positioning tooling of this solution can be easily removed from between the battery module and the box body.

[0013] To sum up, the battery module box positioning tooling of the present scheme can achieve reliable positioning of the battery module relative to the box body when the elastic element is unfolded; and when the elastic element is compressed, it can be conveniently and quickly placed between the battery module and the box body, or taken out from between the battery module and the box body. There is no need to move the battery module before taking it out as in the prior art, so the box insertion accuracy of the battery module will not be damaged, and it has higher operating efficiency.

[0014] As a preferred solution of the utility model, an insulating layer is provided at one end of the second positioning block away from the first positioning block, and a surface of the insulating layer away from the first positioning block is a second contact surface.

[0015] The specific structural forms of the insulating layer include but are not limited to insulating coating, insulating sleeve, and insulating board.

[0016] This solution can prevent short circuit between the battery module and the second positioning block, thereby ensuring the safety of the box-in operation.

[0017] As a preferred solution of the present utility model, the insulating layer is a silicone material component.

[0018] This solution recommends that the insulating layer be made of silicone material components, which have good elasticity while ensuring insulation and can adapt to uneven surfaces, thereby better fitting with the surface of the battery module and improving the positioning effect.

[0019] As a preferred solution of the utility model, a limiting element can be detachably provided between the first positioning block and the second positioning block, and the limiting element is used to prevent the first positioning block and the second positioning block from approaching each other.

[0020] The specific structural forms of the limiting element include but are not limited to block, column, plate; detachable settings, such as bonding, threaded connection, snap connection, pin connection;

[0021] In this solution, a detachable limiting element is added between the first positioning block and the second positioning block, which can prevent the elastic element from being accidentally compressed due to external force interference during the box-loading operation, thereby causing the limiting failure between the battery module and the box body.

[0022] As a preferred solution of the utility model, the limiting element includes a limiting bolt, one end of the limiting bolt is threadedly connected to the second positioning block, and the other end of the limiting bolt abuts against the first positioning block.

[0023] This proposal recommends a specific limiting element, which can directly use mature standard bolts or be modified through standard bolts. It has a simple and reliable structure and low cost.

[0024] As a preferred solution of the utility model, a limiting slot is provided on the first positioning block, the shape and size of the limiting slot matches the shape and size of the box side wall section, and the side of the limiting slot away from the second positioning block is the first contact surface.

[0025] During installation, the solution is to clamp the limiting slot of the first positioning block on the side wall of the box body, and then abut the second positioning block against the battery module. This solution is suitable for boxes with smaller side wall cross-sections.

[0026] As a preferred solution of the utility model, a limiting protrusion is provided on the first positioning block, and a side of the limiting protrusion facing away from the second positioning block is the first contact surface.

[0027] During installation, this solution is to place the side of the limiting protrusion facing away from the second positioning block against the side wall of the box, and then place the second positioning block against the battery module. This solution is suitable for boxes with larger side wall cross-sections where it is inconvenient to set limiting slots.

[0028] As a preferred solution of the utility model, one of the first positioning block and the second positioning block is provided with a limiting shaft, the other of the first positioning block and the second positioning block is provided with a limiting hole, and the limiting shaft is slidably connected to the limiting hole.

[0029] The limiting shaft and the limiting hole are arranged in a manner, for example, the limiting shaft is arranged in the first positioning block and the limiting hole is arranged in the second positioning block; or the limiting shaft is arranged in the second positioning block and the limiting hole is arranged in the first positioning block.

[0030] This solution recommends a specific sliding connection implementation method, which can be realized through ordinary machining, has a simple and reliable structure, does not require the purchase of slide rails, and has a low cost.

[0031] As a preferred solution of the utility model, the number of the limiting shafts is greater than one, and the limiting shafts are arranged side by side and spaced apart; the number of the limiting holes matches the number of the limiting shafts.

[0032] This solution recommends using multiple limit shafts to achieve sliding connection, which can make the second positioning block slide more smoothly relative to the first positioning block and reduce the probability of the second positioning block getting stuck relative to the first positioning block.

[0033] As a preferred solution of the present invention, the elastic element includes a coil spring.

[0034] This proposal recommends a specific elastic element structure, which has the advantages of long service life and low cost.

[0035] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0036] 1. The battery module box positioning tool of the utility model can realize the reliable positioning of the battery module relative to the box body, and when it is necessary to take out the battery module from between the battery module and the box body, there is no need to move the battery module first as in the prior art, so the box insertion accuracy of the battery module will not be damaged, and the operation efficiency is higher.

[0043] The utility model is described in detail below in conjunction with the accompanying drawings.

[0044] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0045] In the description of the following specific embodiments, the terms indicating the orientation or position relationship such as "upper", "lower", "left", "right", "center", "inside", "outside", etc. are all based on the expression of the orientation or position relationship shown in the drawings, or the orientation or position relationship when the device / apparatus is usually used. These terms of orientation or position relationship are only for the convenience of description or simplification of the description in the specific embodiments, so that technicians can quickly understand the scheme, rather than indicating or implying that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific position relationship, and therefore cannot be understood as a limitation of the present invention.

[0046] The terms "horizontal", "vertical" and the like do not require the corresponding devices / components / elements to be absolutely horizontal or vertical or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simply understood that the corresponding devices / components / elements are set in specific directions such as "horizontal" and "vertical", and can have an error / deviation of ±10% relative to the corresponding direction setting, more preferably an error / deviation within ±8%, more preferably an error / deviation within ±6%, more preferably an error / deviation within ±5%, and more preferably an error / deviation within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its role in the solution of the utility model.

[0047] The terms “first”, “second”, “third”, etc. are merely used to distinguish the same or similar components and should not be understood as emphasizing or implying the relative importance of specific components.

[0048] The terms "set", "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be welding, riveting, bolting, threaded connection and other commonly used connection methods in the field. It can be directly connected or indirectly connected through an intermediate medium. It can also be the internal connection of two elements.

[0049] Example 1

[0050] like Figures 1 to 3 As shown, a battery module box positioning tool used in this embodiment includes:

[0051] A first positioning block 1, the first positioning block 1 having a first contact surface 10, the first contact surface 10 is used to abut against the inner wall of the box body 6;

[0052] A second positioning block 2, the second positioning block 2 is slidably connected to the first positioning block 1, and the second positioning block 2 has a second contact surface 20 at one end away from the first positioning block 1, and the second contact surface 20 is used to abut against the battery module 5;

[0053] The elastic element 3 has two ends respectively abutting against the first positioning block 1 and the second positioning block 2 , and the elastic element 3 is used for driving the first positioning block 1 and the second positioning block 2 to move away from each other.

[0054] like Figure 2 The figure is a schematic diagram of the working state of the present embodiment when used for relative positioning of the battery module 5 and the box body 6. It can be seen that the first contact surface 10 of the first positioning block 1 abuts against the inner wall of the box body 6 (i.e. Figure 2 The second positioning block 2 extends to the right relative to the first positioning block 1 under the pressure of the elastic element 3, so that its second contact surface 20 abuts against the outer wall of the battery module 5.

[0055] Furthermore, an insulating layer 21 is provided at one end of the second positioning block 2 away from the first positioning block 1, and a surface of the insulating layer 21 away from the first positioning block 1 is a second contact surface 20. Furthermore, the insulating layer 21 is a silicone material component.

[0056] Furthermore, a limiting element 4 can be detachably provided between the first positioning block 1 and the second positioning block 2 , and the limiting element 4 is used to prevent the first positioning block 1 and the second positioning block 2 from approaching each other.

[0057] Furthermore, the limiting element 4 comprises a limiting bolt, one end of which is threadedly connected to the second positioning block 2, and the other end of which abuts against the first positioning block 1. Specifically, Figure 3 As shown, the limiting bolt of this embodiment directly adopts a hexagon socket bolt, and its axis is parallel to the direction of freedom of movement of the second positioning block 2 relative to the first positioning block 1 (i.e., along Figure 3 The limit bolt can be moved upward by rotating it until it can abut against the second positioning block 2 to prevent the second positioning block 2 from approaching the first positioning block 1, which is suitable for the situation where the box-entering operation is in progress; or the limit bolt can be moved downward by rotating it until it is buried in its threaded hole, so that the second positioning block 2 can freely approach the first positioning block 1, which is suitable for the situation where the box-entering operation has not yet started or has been completed; a through hole for convenient insertion of the limit bolt and a screwdriver is provided on the side of the limit bolt away from the second positioning block 2.

[0058] Furthermore, a limiting slot 11 is provided on the first positioning block 1, and the shape and size of the limiting slot 11 match the shape and size of the cross section of the side wall of the box body 6, and the side of the limiting slot 11 away from the second positioning block 2 is a first contact surface 10. Figure 2 As shown, the cross section of the side wall of the box body 6 in this embodiment is rectangular, so the limit slot 11 in this embodiment is also rectangular, and its width (along the Figure 2 The dimension in the left-right direction) is greater than or equal to the dimension corresponding to the side wall of the box body 6, so that the first positioning block 1 can be buckled on the side wall of the box body 6.

[0059] Furthermore, one of the first positioning block 1 and the second positioning block 2 is provided with a limiting shaft 22, and the other of the first positioning block 1 and the second positioning block 2 is provided with a limiting hole 13, and the limiting shaft 22 is slidably connected to the limiting hole 13. Figure 3 As shown, the limiting shaft 22 of this embodiment is connected to the second positioning block 2 by screws, and the limiting hole 13 is set in the first positioning block 1. When the second positioning block 2 is close to the first positioning block 1, the limiting shaft 22 is in the limiting hole 13 along the Figure 3 When the second positioning block 2 is away from the first positioning block 1, the limiting shaft 22 moves along the limiting hole 13 Figure 3 Move upward in the up-down direction; a limiting step is also provided at the end of the limiting shaft 22 away from the second positioning block 2, and the corresponding limiting hole 13 is also a step hole. The cooperation between the limiting step and the step hole can prevent the limiting shaft 22 from moving upward for too long, causing the limiting shaft 22 to escape from the limiting hole 13.

[0060] Furthermore, the number of the limiting shafts 22 is greater than one, and the limiting shafts 22 are arranged side by side and spaced apart; the number of the limiting holes 13 matches the number of the limiting shafts 22. Figure 3 As shown, the number of the limiting shafts 22 in this embodiment is two, and they are symmetrically arranged relative to the symmetry plane of the first positioning block 1 and the second positioning block 2, so as to ensure that the second positioning block 2 can slide smoothly relative to the first positioning block 1.

[0061] Furthermore, the elastic element 3 comprises a coil spring. Figure 3 As shown, in this embodiment, the number of elastic elements 3 is two, and they are also symmetrically arranged relative to the symmetry plane of the first positioning block 1 and the second positioning block 2, so as to ensure that the first positioning block 1 and the second positioning block 2 are subjected to balanced forces.

[0062] Example 2

[0063] like Figures 4 to 5 As shown, on the basis of Embodiment 1, further, a limiting protrusion 12 is provided on the first positioning block 1 , and a surface of the limiting protrusion 12 facing away from the second positioning block 2 is a first contact surface 10 .

[0064] like Figure 51 is a schematic diagram of the working state of the embodiment when the battery module 5 and the box body 6 are relatively positioned. It can be seen that the first contact surface 10 of the first positioning block 1 abuts against the inner wall of the box body 6 (i.e. Figure 5 The second positioning block 2 extends to the right relative to the first positioning block 1 under the pressure of the elastic element 3, so that its second contact surface 20 abuts against the outer wall of the battery module 5. It can be seen that the thickness of the side wall of the box body 6 (along the Figure 5 The dimension in the left-right direction) is smaller than the dimension corresponding to the limiting slot 11, so this embodiment is more suitable for situations where the side wall dimension of the box body 6 is larger.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
