Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a battery cell clamp. Background Technology

[0002] Current battery cell clamps use cylinders to drive the grippers to clamp the battery cells from both sides in the horizontal direction. The battery cells are not clamped and fixed in the vertical direction. Therefore, a large force needs to be applied in the horizontal direction to increase the friction between the battery cells and the grippers in the vertical direction to clamp the battery cells. If the clamping force is too large, it can easily damage the battery cells. Utility Model Content

[0003] The main objective of this application is to provide a battery cell clamp that aims to at least improve the technical problem in the related art where battery cell clamps do not clamp and fix the battery cell in the vertical direction.

[0004] To achieve the above objectives, according to some embodiments of this application, this application provides a battery cell clamp for clamping a battery cell, including a clamp body, a first positioning member, two second positioning members, a support member, and a hinge structure. The clamp body includes an upper clamp and a lower clamp. The two first positioning members are disposed on the side of the upper clamp along a first direction, and the two second positioning members are disposed on opposite sides of the upper clamp along a second direction. The support member is disposed on the second positioning members and is used to provide vertical support for the battery cell. The hinge structure is used to drive the support member to move along a third direction through the upper clamp to adjust the distance between the support member and the lower clamp. The first direction, the second direction, and the third direction are arranged perpendicularly to each other.

[0005] The battery cell is positioned along a first direction by a first positioning member, and the battery cell is clamped and positioned from both sides along a second direction by two second positioning members. The battery cell is supported by a support member. The distance between the clamp and the support member is adjusted by a hinge structure to support and clamp the battery cell in a third direction. This embodiment can clamp the battery cell in the vertical direction and provide vertical support for the battery cell on the basis of horizontal clamping, thereby improving the stability of battery cell clamping and reducing the risk of battery cell damage.

[0006] In some embodiments, the second positioning member includes a plurality of second positioning sub-members, which are arranged at intervals along the first direction, and each second positioning sub-member is provided with the support member.

[0007] By setting multiple second positioning sub-components spaced apart along the first direction, and providing a support member on each second positioning sub-component, the battery cell can be positioned and supported from various positions along the first direction.

[0008] In some embodiments, the support member includes a connecting rod, a support plate, and a slider mounted on the support plate. A plurality of support plates are respectively mounted on the connecting rod. The support plates are disposed on the side of the lower clamp away from the upper clamp to provide vertical support for the battery cell. The second positioning sub-component includes a positioning rod and a slide rail mounted on the positioning rod. The positioning rod is connected to the upper clamp, and the slide rail is slidably connected to the slider.

[0009] By setting up a support plate and having a slider slide along the rail, the support plate can be extended into the bottom of the battery cell, providing vertical support for the cell and preparing for subsequent vertical clamping. Furthermore, connecting multiple support plates via connecting rods allows for synchronized adjustment, maintaining consistency in the adjustment process.

[0010] In some embodiments, the slider is provided with a slide groove, a slide bar is provided on the side wall of the slide groove, the slide rail is slidably installed in the slide groove, and the slide rail is provided with a groove that slides with the slide bar.

[0011] By setting a groove to accommodate the slide rail, the left and right movement of the slide rail can be limited, reducing the possibility of the slide rail falling off. Furthermore, a sliding strip is set in the groove to cooperate with the groove on the slide rail to achieve a sliding connection.

[0012] In some embodiments, the second positioning component further includes a limiting block disposed at one end of the slide rail along the sliding direction, the limiting block being used to abut against the slider to limit the sliding stroke of the slide rail.

[0013] By setting a limiting block at the end of the slide rail along the sliding direction, the movement stroke of the slider can be limited, preventing the slider from moving too far and falling off the slide rail.

[0014] In some embodiments, the support member has a buffer layer on the side facing the lower clamp.

[0015] By setting a buffer layer on the support, which allows direct contact between the support and the battery cell, the risk of the battery cell being damaged by compression and surface scratches can be reduced.

[0016] In some embodiments, the hinge structure includes a mounting bracket, an adjusting member mounted on the mounting bracket, and a connecting member connected to the adjusting member. The mounting bracket is mounted on the upper clamp, the connecting member is connected to the lower clamp, and the adjusting member drives the support member to move in a third direction via the upper clamp to adjust the distance between the support member and the lower clamp.

[0017] The hinge structure includes a mounting bracket, an adjusting member, and a connector connected to the adjusting member. The mounting bracket provides the installation position, and the connector connects to the lower clamp. Under external force, the adjusting member can move the mounting bracket and the upper clamp connected to the mounting bracket upwards in a third direction, clamping the battery cell between the support member and the lower clamp. The operation can be completed manually and is simple.

[0018] In some embodiments, the connector includes a connecting shaft, a locking nut, and a first clamping block and a second clamping block spaced apart from the connecting shaft. The first clamping block and the second clamping block abut against opposite sides of the lower clamp. The locking nut is located on the side of the first clamping block away from the second clamping block and is threadedly connected to the connecting shaft.

[0019] By configuring the connector, which includes a connecting shaft, a locking nut, and a first and second clamping block spaced apart from the connecting shaft, the connector can be securely locked onto the lower clamp. During subsequent adjustment, the lower clamp and the connector can remain relatively stationary.

[0020] In some embodiments, the adjusting member includes a pressure handle and a first link, a second link, and a third link that are hinged sequentially. The end of the first link away from the second link is connected to the pressure handle, and the end of the third link away from the second link is connected to the connecting shaft.

[0021] The adjustment mechanism includes a pressure handle and a first link, a second link, and a third link that are hinged in sequence. The end of the first link away from the second link is connected to the pressure handle, and the end of the third link away from the second link is connected to the connecting shaft. When a person drives the pressure handle to fall, the upper clamp can be driven to move up or down through the first link, the second link, and the third link.

[0022] In some embodiments, the fixture body further includes a guide locking member, which includes a linear bearing and a guide rod. The upper fixture is provided with an upper sliding hole, the lower fixture is provided with a lower sliding hole, and the linear bearing is provided with a mounting hole. The upper sliding hole, the lower sliding hole, and the mounting hole are coaxially arranged. The guide rod passes through the mounting hole, the upper sliding hole, and the lower sliding hole in sequence, and the guide rod is slidably connected to the upper fixture.

[0023] By setting guide rods and linear bearings, the movement of the upper and lower clamps can be limited and assisted.

[0024] In some embodiments, the guide locking member further includes a limiting nut, which is mounted on the guide rod, and the lower clamp, the upper clamp, the linear bearing, and the limiting nut are arranged sequentially along the central axis of the guide rod.

[0025] By setting a limiting nut on the guide rod, the movement stroke of the upper clamp can be limited, reducing the risk of the upper clamp falling off the guide rod.

[0026] In some embodiments, the first positioning member includes a base and a buffer pad mounted on the base, the base being connected to the upper clamp, and the buffer pad being used to abut against the battery cell.

[0027] By setting the first positioning component, which includes a base and a buffer component, the base provides rigid support and the buffer component plays a buffering role, which can reduce the risk of deformation or scratches caused by excessive instantaneous force on the battery cell.

[0028] In some embodiments, the cell clamp further includes a handle connected to the lower clamp.

[0029] By adding handles, the upper and lower clamps can be moved easily.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0051] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.

[0053] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0055] The descriptions of directions such as "up", "down", "front", "back", "left", and "right" in this application are based on the directions shown in the accompanying drawings and are only used to explain the relative positional relationships between the components in the posture shown in the accompanying drawings.

[0056] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0057] In related technologies, battery cell clamps typically hold the cells horizontally. Specifically, a cylinder drives two horizontally opposed jaws to move closer together to clamp the cell, and the jaws move away to release it. Horizontal clamping is suitable for situations with a large clamping surface. However, when the cell is placed horizontally, such as a prismatic cell, the clamping surface is small, and horizontal clamping alone can easily lead to instability. To achieve stable clamping, the clamping force must be increased, which can easily damage the cell.

[0058] To address this, the applicant provides a battery cell clamp, comprising a clamp body, a first positioning element, two second positioning elements, a support element, and a hinge structure. The clamp body includes an upper clamp and a lower clamp. The first positioning element is disposed on opposite sides of the upper clamp along a first direction, and the two second positioning elements are disposed on opposite sides of the upper clamp along a second direction. The support element is disposed on the second positioning elements and provides vertical support for the battery cell. The hinge structure includes a mounting frame, an adjusting element mounted on the mounting frame, and a connecting element connected to the adjusting element. The mounting frame is mounted on the upper clamp, and the connecting element is connected to the lower clamp. The adjusting element is used to drive the support element to move along a third direction via the upper clamp to adjust the distance between the support element and the lower clamp. The first direction, the second direction, and the third direction are arranged perpendicularly to each other. The first direction can be the X direction, the second direction can be the Y direction, and the third direction can be the Z direction. The Z direction, being vertical, provides vertical support through the support element, providing upward support for the battery cell and reducing the risk of the battery cell falling. This application enables the clamping of battery cells from three directions, providing vertical support for the battery cells on the basis of horizontal clamping, thereby improving the stability of battery cell clamping and reducing the risk of battery cell damage.

[0059] Please refer to Figure 1 , Figure 1This is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of this application. The electrical device can be the vehicle 1000, which can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. A battery 100 is disposed inside the vehicle 1000, and the battery 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery 100 can be used to power the vehicle 1000; for example, the battery 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during starting, navigation, and driving.

[0060] In some embodiments of this application, the battery 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0061] Please refer to Figure 2 , Figure 2 This is an exploded structural diagram of a battery 100 provided in some embodiments of this application. The battery 100 includes a housing 10 and a battery cell 20, with the battery cell 20 housed within the housing 10. The housing 10 provides a space for the battery cell 20 and can have various structures. In some embodiments, the housing 10 may include a first portion 11 and a second portion 12, which overlap each other, jointly defining a space for accommodating the battery cell 20. The second portion 12 may be a hollow structure with one open end, and the first portion 11 may be a plate-like structure, covering the open side of the second portion 12 so that the first portion 11 and the second portion 12 jointly define the space. Alternatively, the first portion 11 and the second portion 12 may both be hollow structures with one open side, with the open side of the first portion 11 covering the open side of the second portion 12. Of course, the housing 10 formed by the first portion 11 and the second portion 12 can have various shapes, such as a cylinder, a cuboid, etc.

[0062] In battery 100, there can be multiple cells 20, which can be connected in series, parallel, or in a mixed manner. A mixed connection means that multiple cells 20 are connected in both series and parallel configurations. Multiple cells 20 can be directly connected in series, parallel, or in a mixed manner, and then the entire assembly of the multiple cells 20 is housed within the casing 10. Alternatively, battery 100 can also consist of multiple cells 20 first connected in series, parallel, or in a mixed manner to form battery modules, and then these battery modules are connected in series, parallel, or in a mixed manner to form a whole, which is also housed within the casing 10. Battery 100 may also include other structures; for example, it may include a busbar component for electrical connection between the multiple cells 20.

[0063] Each cell 20 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these. The cell 20 can be cylindrical, flat, cuboid, or other shapes.

[0064] This application provides a cell clamp for holding and transferring battery cells during battery manufacturing.

[0065] Please refer to Figure 3 and Figure 4 According to some embodiments of this application, this application provides a battery cell clamp 1 for clamping a battery cell 20, including a clamp body, a first positioning member 4, two second positioning members, a support member 6, and a hinge structure 7. The clamp body includes an upper clamp 2 and a lower clamp 3. The first positioning member 4 is disposed on the side of the upper clamp 2 along a first direction, and the two second positioning members are disposed on opposite sides of the upper clamp 2 along a second direction. The support member 6 is disposed on the second positioning members and is used to provide vertical support for the battery cell 20. The hinge structure 7 is connected to the upper clamp 2 and is used to drive the support member 6 to move along a third direction through the upper clamp 2 to adjust the distance between the support member 6 and the lower clamp 3. The first direction, the second direction, and the third direction are arranged perpendicularly to each other.

[0066] It should be noted that the first direction, second direction, and third direction referred to in this application correspond to respectively Figure 1The first direction referred to here is the X direction, the second direction is the Y direction, and the third direction is the Z direction, which is vertical. The fixture body includes an upper clamp 2 and a lower clamp 3, which can move relative to each other. The upper clamp 2 and the lower clamp 3 can be square frames. The first direction can refer to the length direction of the square frame. First positioning members 4 are respectively disposed on the sides of the square frame to position the battery cell 20 along the first direction. The second direction can refer to the width direction of the square frame. Two second positioning members are respectively disposed on both sides of the width direction of the square frame to clamp and position the battery cell 20 from both ends along the second direction. In a specific embodiment, the first direction and the second direction are perpendicular to each other. A support member 6 is disposed on the second positioning members. When placing the battery cell 20, the battery cell 20 is placed on the support member 6, and the support member 6 provides vertical support for the battery cell 20. Here, vertical can be the Z direction, that is, providing upward support force in the third direction.

[0067] The hinge structure 7 is used to drive the upper clamp 2 to move. The movement of the upper clamp 2 allows the first positioning member 4, the second positioning member, and the support member 6, which are directly or indirectly mounted on the upper clamp 2, to move. Since the battery cell 20 is placed on the support member 6, the movement of the support member 6 will drive the battery cell 20 to move together, moving it to a position close to the lower clamp 3. Finally, the battery cell 20 will be clamped between the support member 6 and the lower clamp 3 in a third-order upward direction.

[0068] It should be noted that this embodiment can provide vertical support through the support member 6, providing upward support for the battery cell 20 and reducing the risk of the battery cell 20 falling. It is not necessary to use a large horizontal clamping force to clamp the battery cell 20 as in related technologies. Simultaneously, it can clamp the battery cell 20 from three directions, providing vertical support on top of horizontal clamping, improving the stability of the battery cell 20 clamping and reducing the risk of damage to the battery cell 20. Furthermore, there can be two first positioning members 4, respectively disposed on both sides of the upper clamp 2 along the first direction.

[0069] The first positioning member 4 initially positions the battery cell 20 along the first direction. Two second positioning members clamp and position the battery cell 20 from both sides along the second direction. The support member 6 supports the battery cell 20. The distance between the lower clamp 3 and the support member 6 is adjusted by the hinge structure to support and clamp the battery cell 20 in the third direction. This embodiment can achieve positioning or clamping of the battery cell 20 in the vertical direction, providing vertical support for the battery cell 20 on the basis of horizontal clamping, improving the stability of the battery cell 20 clamping and reducing the risk of damage to the battery cell 20.

[0070] Please refer to Figure 5In some embodiments, the second positioning element includes a plurality of second positioning sub-elements 51, which are arranged at intervals along a first direction, and each second positioning sub-element 51 is provided with a support member 6.

[0071] When the length of the battery cell 20 in the first direction is relatively long, such as when one battery cell 20 includes two bare cells, the two bare cells laid flat will have a considerable length. If clamped from only one position in the first direction, firstly, the clamping may be unstable, and secondly, the bare cells that are not clamped or supported may fall, causing the tabs connecting the two bare cells to crack under stress. To reduce the risk of the above problems, the second positioning member can be configured to include multiple second positioning sub-members 51, which clamp and position the battery cell 20 from multiple positions along its length. At the same time, a support member 6 is provided on each second positioning sub-member 51, which can also provide vertical support for the battery cell 20 from various positions, reducing the risk of the bare cells tilting and falling or the tabs cracking. Of course, similarly, the first positioning member 4 can also include multiple first positioning sub-members, which are arranged along the second direction to clamp and position the battery cell 20 from multiple positions in the second direction, suitable for situations where the battery width is large. By setting a second positioning component including multiple second positioning sub-components 51, and each second positioning sub-component 51 is provided with a support member 6, the battery cell 20 can be positioned and supported from various positions in the first direction.

[0072] By setting multiple second positioning sub-components 51 arranged at intervals along the first direction, and providing a support member 6 on each second positioning sub-component 51, the battery cell 20 can be positioned and supported from various positions in the first direction.

[0073] Please refer to Figure 6 and Figure 7 In some embodiments, the support member 6 includes a connecting rod 61, a support plate 62, and a slider 63 mounted on the support plate 62. Multiple support plates 62 are respectively mounted on the connecting rod 61. The support plate 62 is located on the side of the lower clamp 3 away from the upper clamp 2 and is used to provide vertical support for the battery cell 20. The second positioning sub-member 51 includes a positioning rod 511 and a slide rail 512 mounted on the positioning rod 511. The positioning rod 511 is connected to the upper clamp 2, and the slide rail 512 is slidably connected to the slider 63.

[0074] The support plate 62 can be a flat plate with the supporting surface facing the lower clamp 3. The battery cell 20 is placed in the receiving space formed by the supporting surface and the lower clamp 3. The positioning rod 511 is used to abut against the side of the battery cell 20. The positioning rods 511 on both sides of the battery cell 20 realize the positioning and clamping of the battery cell 20 in the second direction. The slide rail 512 is movably connected to the slider 63. Multiple support plates 62 can also be connected to the connecting rod 61 respectively. By connecting multiple support plates 62 through the connecting rod 61, or in other words, by installing multiple support plates 62 on the connecting rod 61, the synchronous adjustment of multiple support plates 62 can be realized, improving the consistency of the adjustment steps. The specific adjustment process can be as follows: First, the first positioning member 4 positions the battery cell 20 in the X direction. Then, the second positioning member positions and clamps the battery cell 20 in the Y direction. Next, the slider 63, in cooperation with the slide rail 512, pushes the support plate 62 to slide along the slide rail 512, moving the support plate 62 towards the receiving space, placing it on the bottom surface of the battery cell 20, thus providing vertical support. At this time, since the connecting rod 61 connects multiple support plates 62 simultaneously, it has the function of linking multiple support plates 62, thereby improving the consistency of the adjustment steps. Then, the hinge structure 7 drives the upper clamp 2 to move, thereby driving the second positioning member and the support plate 62 to move synchronously, clamping the battery cell 20 between the support plate 62 and the lower clamp 3.

[0075] By setting a support plate 62 and sliding it along the slide rail 512 via a slider 63, the support plate 62 can be extended into the bottom of the battery cell 20, providing vertical support for the battery cell 20 and preparing for subsequent vertical clamping of the battery cell 20. At the same time, by connecting multiple support plates 62 via a connecting rod 61, it is possible to achieve coordinated adjustment and maintain the consistency of adjustment steps.

[0076] Please refer to Figure 7 In some embodiments, the slider 63 is provided with a groove, a slide bar is provided on the side wall of the groove, the slide rail 512 is slidably installed in the groove, and the slide rail 512 is provided with a groove 513 that slides with the slide bar.

[0077] The slide groove is a recessed groove that runs through the slider 63 along its length. The slide rail 512 is a long rectangular block set inside the slide groove. The sidewall of the slide groove can limit the slide rail 512, reducing the possibility of the slide rail 512 falling off. At the same time, a slide bar is provided on the sidewall of the slide groove. The slide bar can be an arc-shaped protrusion with a smooth surface and is set on opposite sides of the sidewall of the groove. A groove 513 is provided at the corresponding position of the slide rail 512 to slide and engage with the slide bar. The slider 63 and the slide rail 512 can slide relative to each other to adjust the position of the second positioning member or support member 6. Specifically, it can make the support plate 62 slide below the battery cell 20.

[0078] By setting a groove to accommodate the slide rail 512, the left and right movement of the slide rail 512 can be limited, reducing the possibility of the slide rail 512 falling off. Furthermore, a slider is set in the groove to cooperate with the groove 513 on the slide rail 512 to achieve a sliding connection.

[0079] Please refer to Figure 7 In some embodiments, the second positioning component 51 further includes a limiting block 514, which is disposed at one end of the slide rail 512 along the sliding direction. The limiting block 514 is used to abut against the slider 63 to limit the sliding stroke of the slide rail 512.

[0080] The limiting block 514 can be a cube or a plate, and is set at the end of the slide rail 512. Specifically, it can be set at the end of the slide rail 512 closer to the receiving space, or at the end of the slide rail 512 further away from the receiving space, or at both ends of the slide rail 512. The slider 63 will slide relative to the slide rail 512. The limiting block 514 is set at the end of the slide rail 512 along the sliding direction, that is, at the end of the length direction of the slide rail 512. When the slider 63 slides to the end of the slide rail 512, it will hit the limiting block 514 and stop, which will limit the movement stroke of the slider 63 and prevent the slider 63 from sliding off the end of the slide rail 512.

[0081] By setting a limiting block 514 at the end of the slide rail 512 along the sliding direction, the movement stroke of the slider 63 can be limited, preventing the slider 63 from moving too far and falling off the slide rail 512.

[0082] Please refer to Figure 7 In some embodiments, a buffer layer 64 is provided on the side of the support member 6 facing the lower clamp 3.

[0083] The lower clamp 3 is located above the support member 6. The side of the support member 6 facing the lower clamp 3, which is also the top surface or the side facing the receiving space, is also the side facing the receiving space. The buffer layer 64 can be an elastic buffer layer, made of rubber, silicone, or foam, to provide cushioning. Specifically, the buffer layer 64 can be set on the support surface. During clamping and support, the battery cell 20 is placed on the buffer layer 64. The buffer layer 64 can not only prevent the battery cell 20 from being squeezed and damaged due to excessive impact force, but also prevent the battery cell 20 from directly contacting the harder support plate 62, thus reducing the risk of scratches on the surface of the battery cell 20. Similarly, a buffer structure can also be set on the side of the first positioning member 4 and the second positioning member that contacts the battery cell 20, or the side facing the receiving space. A buffer block 31 can also be set on the side of the lower clamp 3 facing the receiving space.

[0084] By providing a buffer layer 64 on the support member 6, which allows direct contact between the buffer layer 64 and the battery cell 20, the risk of the battery cell 20 being damaged by compression and surface scratches can be reduced.

[0085] Reference Figures 8-10 In some embodiments, the hinge structure 7 includes a mounting frame 71, an adjusting member 72 mounted on the mounting frame 71, and a connecting member 73 connected to the adjusting member 72. The mounting frame 71 is mounted on the upper clamp 2, and the connecting member 73 is connected to the lower clamp 3. The adjusting member 72 is used to drive the support member 6 to move along a third direction through the upper clamp 2 to adjust the distance between the support member 6 and the lower clamp 3.

[0086] Specifically, the hinge structure 7 includes a mounting bracket 71, an adjusting member 72 mounted on the mounting bracket 71, and a connecting member 73 connected to the adjusting member 72. The mounting bracket 71 is mounted on the upper clamp 2, and the connecting member 73 is connected to the lower clamp 3. The adjusting member 72 is used to drive the support member 6 to move along a third direction via the upper clamp 2 to adjust the distance between the support member 6 and the lower clamp 3. The mounting bracket 71 is mounted on the upper clamp 2, and the connecting member 73 is used to connect to the lower clamp 3. In use, the lower clamp 3 can be held still, and the adjusting member 72 can be driven by external force to move the mounting bracket 71 and the upper clamp 2 connected to the mounting bracket 71 upward along a third direction. At this time, the support member 6 also moves upward along a third direction with the upper clamp 2, and also moves towards the lower clamp 3. The driving of the adjusting member 72 stops when the battery cell 20 on the support member 6 abuts against the lower clamp 3. At this time, in the third direction, the battery cell 20 is clamped between the support member 6 and the lower clamp 3. In this way, the battery cell 20 can be positioned or clamped in three directions.

[0087] The hinge structure 7 includes a mounting bracket 71, an adjusting member 72 mounted on the mounting bracket 71, and a connecting member 73 connected to the adjusting member 72. The mounting bracket 71 provides the installation position, and the connecting member 73 is connected to the lower clamp 3. Under external force, the adjusting member 72 can drive the mounting bracket 71 and the upper clamp 2 connected to the mounting bracket 71 to move upward in a third direction, clamping the battery cell 20 between the support member 6 and the lower clamp 3. The operation can be completed manually and is simple.

[0088] Please refer to Figure 8 and Figure 9 In some embodiments, the connector 73 includes a connecting shaft 731, a locking nut 732, and a first clamping block 733 and a second clamping block 734 spaced apart from the connecting shaft 731. The first clamping block 733 and the second clamping block 734 respectively abut against opposite sides of the lower clamp 3. The locking nut 732 is disposed on the side of the first clamping block 733 away from the second clamping block 734, and the locking nut 732 is threadedly connected to the connecting shaft 731.

[0089] The two opposite sides of the lower clamp 3 can be an upper side and a lower side, or a top surface and a bottom surface. The top surface refers to the side facing the upper clamp 2, and the bottom surface refers to the side facing the receiving space. The first clamping block 733 and the second clamping block 734 can be circular plate-shaped clamping blocks, respectively abutting against the opposite sides of the lower clamp 3. The locking nut 732 is threadedly connected to the connecting shaft 731 to reduce the risk of the clamping blocks falling off the connecting shaft 731. Specifically, two locking nuts 732 can be provided, and the two locking nuts 732 respectively limit the positions of the first clamping block 733 and the second clamping block 734 from both ends of the connecting shaft 731. In this way, the connecting piece 73 can be firmly installed on the lower clamp 3, facilitating subsequent adjustments.

[0090] By configuring the connector 73, which includes a connecting shaft 731, a locking nut 732, and a first clamping block 733 and a second clamping block 734 spaced apart from the connecting shaft 731, the connector 73 can be securely locked onto the lower clamp 3. During subsequent adjustment by the adjusting member 72, the lower clamp 3 and the connector 73 can remain relatively stationary.

[0091] Please refer to Figure 10 In some embodiments, the adjusting member 72 includes a pressure handle 721 and a first connecting rod 722, a second connecting rod 723 and a third connecting rod 724 that are hinged in sequence. The end of the first connecting rod 722 away from the second connecting rod 723 is connected to the pressure handle 721, and the end of the third connecting rod 724 away from the second connecting rod 723 is connected to a connecting shaft 731.

[0092] The hinge structure 7 in this application can be a commercially available hinge. The entire battery cell 20 installation process is as follows: 1. The battery cell 20 is positioned in the X direction by the first positioning member 4; 2. The battery cell 20 is positioned in the Y direction by the second positioning member, while the support member 6 is pushed to the bottom of the battery cell 20 to provide Z-direction support; 3. By driving the pressure handle 721 of the hinge structure 7, the upper clamp 2 moves upward relative to the lower clamp 3, causing the first positioning member 4, the second positioning member, and the support member 6 connected to the upper clamp 2 to move upward. During the upward movement of the support member 6, the battery cell 20 moves upward together. At this time, the distance between the support member 6 and the lower clamp 3 gradually decreases until the accommodating space between the support member 6 and the lower clamp 3 can just accommodate the lower battery cell 20 and clamp the battery cell 20. In one specific embodiment, the adjusting member 72 includes a pressure handle 721 and a first connecting rod 722, a second connecting rod 723, and a third connecting rod 724 hinged sequentially. The end of the first connecting rod 722 away from the second connecting rod 723 is connected to the pressure handle 721, and the end of the third connecting rod 724 away from the second connecting rod 723 is connected to a connecting shaft 731. A rotating shaft 711 is provided on the mounting bracket 71, and the first connecting rod 722 is fitted onto the rotating shaft 711. When the pressure handle 721 drives the first connecting rod 722 to rotate upward or downward, the rotating shaft 711 can drive the mounting bracket 71 together with the upper clamp 2 to move upward or downward, thereby adjusting the distance between the support member 6 and the lower clamp 3 to clamp the battery cell 20. The pressure handle 721 can be a pressure sleeve fitted onto the first connecting rod 722. In actual operation, to ensure that the lower clamp 3 does not move, one hand can be placed on the lower clamp 3 or the handle 9 connected to the lower clamp 3.

[0093] The adjusting component 72 includes a pressure handle 721 and a first connecting rod 722, a second connecting rod 723, and a third connecting rod 724 that are hinged in sequence. The end of the first connecting rod 722 away from the second connecting rod 723 is connected to the pressure handle 721, and the end of the third connecting rod 724 away from the second connecting rod 723 is connected to a connecting shaft 731. When a person drives the pressure handle 721 to fall, the upper clamp 2 can be driven to move up or down through the first connecting rod 722, the second connecting rod 723, and the third connecting rod 724.

[0094] Please refer to Figure 11 In some embodiments, the fixture body further includes a guide locking member 8, which includes a linear bearing 81 and a guide rod 82. The upper fixture 2 is provided with an upper sliding hole, and the lower fixture 3 is provided with a lower sliding hole. The linear bearing 81 is provided with a mounting hole. The upper sliding hole, the lower sliding hole and the mounting hole are coaxially arranged. The guide rod 82 passes through the mounting hole, the upper sliding hole and the lower sliding hole in sequence, and the guide rod 82 is slidably connected to the upper fixture 2.

[0095] The guide locking component 8 mainly serves a guiding and locking function. Specifically, the guiding function ensures that the upper clamp 2 and lower clamp 3 only undergo relative vertical displacement during their relative movement. Specifically, an upper sliding hole can be provided on the upper clamp 2, and a lower sliding hole can be provided on the lower clamp 3. The linear bearing 81 can be installed inside or on the upper sliding hole, and it is used to ensure the verticality of the guide rod 82. Specifically, the central axes of the upper sliding hole, lower sliding hole, and mounting hole are on the same straight line, i.e., coaxially arranged. The guide rod 82 passes through the three holes in sequence and is slidably connected to the upper clamp 2. Thus, the upper clamp 2 can move up and down along the guide rod 82. The movement of the upper clamp 2 drives the support component 6 to move up and down to clamp or release the battery cell 20 from a vertical position.

[0096] By setting guide rod 82 and linear bearing 81, the movement of upper clamp 2 and lower clamp 3 can be limited and assisted.

[0097] Please refer to Figure 11 In some embodiments, the guide locking member 8 further includes a limiting nut 83, which is installed on the guide rod 82, and the lower clamp 3, the upper clamp 2, the linear bearing 81 and the limiting nut 83 are arranged sequentially along the central axis of the guide rod 82.

[0098] The limiting nut 83 primarily functions to limit the movement of the upper clamp 2. Specifically, the linear bearing 81 is mounted on the top of the upper clamp 2, and the limiting nut 83 is mounted on top of the linear bearing 81 and also on the end of the guide rod 82. This can be a threaded connection, which facilitates installation, disassembly, and maintenance. Under the action of the hinge structure 7, the upper clamp 2 moves upward, and the upper clamp 2 and linear bearing 81 move up and down along the guide rod 82. At this time, a limiting nut 83 is placed at the top of the guide rod 82. When the upper clamp 2 and linear bearing 81 reach contact with the limiting nut 83, they must stop moving. Alternatively, a washer 84 can be provided; the washer 84 can be elastic to improve the tightness of the connection.

[0099] By setting a limiting nut 83 on the guide rod 82, the movement stroke of the upper clamp 2 can be limited, reducing the risk of the upper clamp 2 falling off the guide rod 82.

[0100] In some embodiments, the first positioning member 4 includes a base and a buffer pad mounted on the base. The base is connected to the upper clamp 2, and the buffer pad is used to abut against the battery cell 20.

[0101] The substrate is generally made of rigid materials, such as metal, and further, copper or steel. The buffer pad is a non-rigid or flexible material. During clamping, the buffer pad comes into contact with the battery cell 20 to cushion the impact and prevent the battery cell 20 from being deformed or scratched due to excessive instantaneous force.

[0102] By setting the first positioning component 4, which includes a base and a buffer component, the base provides rigid support and the buffer component plays a buffering role, which can reduce the risk of deformation or scratches caused by excessive instantaneous force on the battery cell 20.

[0103] In some embodiments, the cell clamp 1 further includes a handle 9, which is connected to the lower clamp 3.

[0104] It should be noted that this application has another important feature: compared to the cylinder-driven adjustment in related technologies, this application uses purely manual adjustment, requiring no driving component as a power source during use, thus making it more applicable. When the battery cell 20 needs to be moved from the equipment to a designated location, or inserted into the equipment from outside, the battery cell clamp 1 fixes the battery cell 20 through linkage in the Z and Y directions, limiting the degree of freedom of the battery cell 20, and then it is moved. To facilitate the control of the movement of the battery cell clamp 1, a handle 9 connected to the upper clamp 2 can be provided on it.

[0105] By setting handle 9, the upper clamp 2 and the lower clamp 3 can be moved easily.

[0106] According to some embodiments of this application, this application provides a battery cell clamp 1 for clamping a battery cell 20, including a clamp body, a first positioning member 4, two second positioning members, a support member 6, and a hinge structure 7. The clamp body includes an upper clamp 2 and a lower clamp 3. The first positioning member 4 is disposed on the side of the upper clamp 2 along a first direction, and the two second positioning members are disposed on opposite sides of the upper clamp 2 along a second direction. The support member 6 is disposed on the second positioning members and is used to provide vertical support for the battery cell 20. The hinge structure 7 includes a mounting frame 71, an adjusting member 72 mounted on the mounting frame 71, and a connecting member 73 connected to the adjusting member 72. The mounting frame 71 is mounted on the upper clamp 2, and the connecting member 73 is connected to the lower clamp 3. The adjusting member 72 is used to drive the support member 6 to move along a third direction through the upper clamp 2 to adjust the distance between the support member 6 and the lower clamp 3. The first direction, the second direction, and the third direction are arranged perpendicularly to each other. The second positioning component includes multiple second positioning sub-components 51, which are spaced apart along a first direction. Each second positioning sub-component 51 is provided with a support member 6. The support member 6 includes a connecting rod 61, a support plate 62, and a slider 63 mounted on the support plate 62. The multiple support plates 62 are respectively mounted on the connecting rod 61. The support plate 62 is located on the side of the lower clamp 3 away from the upper clamp 2, and is used to provide vertical support for the battery cell 20. The second positioning sub-component 51 includes a positioning rod 511 and a slide rail 512 mounted on the positioning rod 511. The positioning rod 511 is connected to the upper clamp 2, and the slide rail 512 is slidably connected to the slider 63. The slider 63 is provided with a sliding groove, and a slide bar is provided on the side wall of the groove. The slide rail 512 is slidably mounted in the sliding groove, and the slide rail 512 is provided with a groove 513 that slides with the slide bar. The hinge structure 7 is used to drive the first movement to adjust the size of the clamping space between the lower clamp 3 and the support member 6. This embodiment enables clamping in the Z direction and can be operated manually without any external power source, thus improving the flexibility of the battery cell clamp 1.

[0107] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of this application's specification and drawings under the application concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
