Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery cell positioning technology, and in particular to a battery cell positioning mechanism. Background Technology
[0002] Traditional cell positioning mechanisms are typically only applicable to cells of one size. If the cell model or size changes, the positioning mechanism needs to be re-processed, increasing processing costs and limiting its effectiveness.
[0003] To address this, existing technology provides a battery cell positioning mechanism. A baffle is fixedly mounted on its base plate, abutting against one side of the battery cell. Furthermore, a driving component and a push plate are located on the side of the battery cell away from the baffle. The driving component can move the push plate towards the battery cell, causing it to abut against the surface of the battery cell for positioning, or the driving component can move the push plate away from the battery cell for easier cell installation and removal. This battery cell positioning mechanism can position the battery cell through the cooperation of the push plate and the baffle, and can accommodate battery cells of different sizes. However, a remaining problem is that, due to the height of vertically placed battery cells, the height of the baffle and push plate needs to be increased to position them, resulting in a large space occupation when the battery cell positioning mechanism is not in use. Utility Model Content
[0004] This utility model provides a battery cell positioning mechanism to solve the problem that in order to position vertically placed battery cells, the existing battery cell positioning mechanism requires increasing the height of the baffle and push plate, which results in a large space occupation when the battery cell positioning mechanism is not in use.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] The cell positioning mechanism includes:
[0007] Support base, used to support the battery cells;
[0008] The positioning assembly includes two positioning structures located on opposite sides of the battery cell. Each positioning structure includes a slider and a positioning plate rotatably mounted on the slider. The slider is slidable relative to the support base and has a positioning position and a non-positioning position. When the slider is in the positioning position, it abuts against the side wall of the battery cell. When the slider moves from the positioning position to the non-positioning position, the positioning plate separates from the side wall of the battery cell and rotates relative to the slider toward the support base.
[0009] As a preferred embodiment of the battery cell positioning mechanism, the battery cell is a square battery cell, and two positioning components are provided. In one positioning component, the two positioning structures are respectively located on both sides of the battery cell along a first direction, and in the other positioning component, the two positioning structures are respectively located on both sides of the battery cell along a second direction. The first direction is perpendicular to the second direction, and both the first direction and the second direction are parallel to the upper surface of the support base.
[0010] As a preferred embodiment of the cell positioning mechanism, it further includes a driving component and a guide plate fixedly disposed on the support base. The driving component is used to drive the slider to slide relative to the support base. During the process of the slider moving from the non-positioning position to the positioning position, the guide plate is used to drive the positioning plate to rotate relative to the slider.
[0011] As a preferred embodiment of the cell positioning mechanism, the guide plate has a track groove, and the positioning plate is fixedly connected to a transmission rod. The rotation center of the positioning plate relative to the slider is parallel to and spaced apart from the center line of the transmission rod. The transmission rod is disposed in the track groove, and the track groove has a first arc-shaped extension groove. During the movement of the slider, the transmission rod can move under the guidance of the first extension groove to drive the positioning plate to rotate relative to the slider.
[0012] As a preferred embodiment of the cell positioning mechanism, the slider also has an intermediate position located between the positioning position and the non-positioning position, and the track groove also has a second extension groove. The extension direction of the second extension groove is parallel to the upper surface of the support base. During the process of the slider moving from the non-positioning position to the intermediate position, the transmission rod can move under the guidance of the first extension groove to drive the positioning plate to rotate relative to the slider. During the process of the slider moving from the intermediate position to the positioning position, the transmission rod is always located in the second extension groove and moves along the extension direction of the second extension groove.
[0013] As a preferred embodiment of the cell positioning mechanism, the positioning plate is fixedly connected to a shaft, the slider is connected to a bearing, and the shaft is located within the inner ring of the bearing.
[0014] As a preferred embodiment of the cell positioning mechanism, the driving component includes a fixed end and a telescopic end capable of reciprocating relative to the fixed end. The fixed end is connected to the support base, and the telescopic end is connected to the slider.
[0015] As a preferred embodiment of the cell positioning mechanism, the upper surface of the support base is parallel to the horizontal plane. When the slider is in the positioning position, the positioning plate is perpendicular to the horizontal plane, and when the slider is in the non-positioning position, the positioning plate is parallel to the horizontal plane.
[0016] As a preferred embodiment of the cell positioning mechanism, the surface of the positioning plate is provided with a rubber pad.
[0017] As a preferred embodiment of the cell positioning mechanism, the support base is provided with a slide rail, and the slider slides in cooperation with the slide rail.
[0018] The beneficial effects of this utility model are:
[0019] This utility model provides a battery cell positioning mechanism, including a support base and a positioning assembly. The support base supports the battery cell. The positioning assembly includes two positioning structures located on both sides of the battery cell. Each positioning structure includes a slider and a positioning plate rotatably mounted on the slider. The slider can slide relative to the support base and has a positioning position and a non-positioning position. When the slider is in the positioning position, the positioning plate abuts against the side wall of the battery cell. Thus, when both sliders of the positioning structures are in the positioning position, the two positioning plates can abut against the two opposite side walls of the battery cell, thereby achieving positioning of the battery cell. When the slider moves from the positioning position to the non-positioning position, the positioning plate can separate from the side wall of the battery cell and rotate relative to the slider towards the support base. This removes the limiting effect of the positioning plate on the battery cell, and the height of the positioning plate decreases as it rotates relative to the slider towards the support base, thus reducing the space occupied by the battery cell positioning mechanism when not in use.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact with the second feature, or contact with the second feature through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the feature being directly above or diagonally above the second feature, or simply indicates that the feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the feature being directly below or diagonally below the second feature, or simply indicates that the feature is at a lower horizontal level than the second feature.
[0033] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "" and "second" are only used for distinction in description and have no special meaning.
[0034] Existing technology provides a battery cell positioning mechanism, in which a baffle is fixedly mounted on the base plate, the baffle being used to abut against one side of the battery cell. Furthermore, a driving component and a push plate are provided on the side of the battery cell away from the baffle. The driving component can drive the push plate to move towards the battery cell, so that the push plate abuts against the surface of the battery cell to complete the positioning, or the driving component can drive the push plate away from the battery cell to facilitate the installation and removal of the battery cell. This battery cell positioning mechanism can achieve battery cell positioning through the cooperation of the push plate and the baffle, and can adapt to battery cells of different sizes. However, a problem remains: because vertically placed battery cells are relatively tall, in order to position vertically placed battery cells, the height of the baffle and push plate needs to be increased, which results in a large space occupation for the battery cell positioning mechanism when not in use.
[0035] To address the aforementioned issues, this embodiment provides a cell positioning mechanism to solve the problem of large space occupation when not in use in existing cell positioning mechanisms, and can be used in the field of cell positioning technology.
[0036] Reference Figures 1-4 The battery cell positioning mechanism includes a support base 1 and a positioning assembly. The support base 1 supports the battery cell 100. The positioning assembly includes two positioning structures 2, which are located on both sides of the battery cell 100. Each positioning structure 2 includes a slider 21 and a positioning plate 22 rotatably mounted on the slider 21. The slider 21 can slide relative to the support base 1 and has a positioning position and a non-positioning position. When the slider 21 is in the positioning position, the positioning plate 22 can abut against the side wall of the battery cell 100. Therefore, when both sliders 21 of the two positioning structures 2 are in the positioning position, the two positioning plates 22 can abut against the two opposite side walls of the battery cell 100, thereby achieving the positioning of the battery cell 100. At this time, the position of the positioning plate 22 is the positioning position. Figure 1 and Figure 4 The position indicated by the dotted line in the diagram; when the slider 21 moves from the positioning position to the non-positioning position, the positioning plate 22 can separate from the side wall of the battery cell 100 and rotate relative to the slider 21 towards the support base 1, so that the positioning plate 22 no longer limits the battery cell 100, and the height of the positioning plate 22 will decrease as it rotates relative to the slider 21 towards the support base 1, thus reducing the space occupied by the battery cell positioning mechanism when it is not in use.
[0037] Optionally, the upper surface of the support base 1 is parallel to the horizontal plane to provide stable support for the battery cell 100. When the slider 21 is in the positioning position, the positioning plate 22 is perpendicular to the horizontal plane, that is, the positioning plate 22 is perpendicular to the upper surface of the support base 1 to improve the limiting effect.
[0038] Optionally, when the slider 21 is in the non-positioning position, the angle between the positioning plate 22 and the horizontal plane is less than 30°, so that the height of the positioning plate 22 does not exceed half the height of the positioning plate 22 when it is perpendicular to the horizontal plane. More preferably, when the slider 21 is in the non-positioning position, the positioning plate 22 is parallel to the horizontal plane, so that the height of the positioning plate 22 is minimized, thereby minimizing the space occupied by the cell positioning mechanism when it is not in use.
[0039] Continue to refer to Figures 1-4 The system comprises two positioning components. One component has two positioning structures 2 located on either side of the battery cell 100 along a first direction, while the other component has two positioning structures 2 located on either side of the battery cell 100 along a second direction. The first direction is perpendicular to the second direction, and both directions are parallel to the upper surface of the support base 1. This allows the two positioning components to position the battery cell 100 along the first and second directions respectively, thus improving the positioning effect. The battery cell 100 can be a square cell with adjacent sidewalls perpendicular to each other. The four positioning structures 2 of the two positioning components can abut against the four sidewalls of the battery cell 100 and provide positioning. Alternatively, the battery cell 100 can be a cylindrical cell, with all four positioning structures 2 of the two positioning components abutting against the outer peripheral wall of the battery cell 100. In other embodiments, to improve the positioning effect on cylindrical cells, a greater number of positioning components can be provided, such as three or four.
[0040] Continue to refer to Figures 1-4 The cell positioning mechanism also includes a driving component 3 and a guide plate 4 fixedly mounted on the support base 1. The driving component 3 drives the slider 21 to slide relative to the support base 1. During the movement of the slider 21 from the non-positioning position to the positioning position, the guide plate 4 drives the positioning plate 22 to rotate relative to the slider 21. In this embodiment, four driving components 3 and four guide plates 4 are provided, and the four driving components 3, four guide plates 4, and four positioning structures 2 of the two positioning components are arranged in a one-to-one correspondence.
[0041] Continue to refer to Figures 1-4 The guide plate 4 has a track groove 41, and the positioning plate 22 is fixedly connected to a transmission rod 23. The rotation center of the positioning plate 22 relative to the slider 21 is parallel to and spaced apart from the center line of the transmission rod 23. The transmission rod 23 is disposed in the track groove 41, which has a first arc-shaped extension groove 411. During the movement of the slider 21, the transmission rod 23 can move under the guidance of the first extension groove 411 to drive the positioning plate 22 to rotate relative to the slider 21. With this configuration, the positioning plate 22 can be driven to rotate relative to the slider 21 through the side wall of the track groove 41 during the sliding of the slider 21. Thus, only one driving component 3 is needed to make the slider 21 slide while the positioning plate 22 rotates relative to the slider 21.
[0042] Continue to refer to Figures 1-4 The slider 21 also has an intermediate position located between the positioning position and the non-positioning position. The track groove 41 also has a second extension groove 412. The extension direction of the second extension groove 412 is parallel to the upper surface of the support base 1. During the process of the slider 21 moving from the non-positioning position to the intermediate position, the transmission rod 23 can move under the guidance of the first extension groove 411 to drive the positioning plate 22 to rotate relative to the slider 21. During the process of the slider 21 moving from the intermediate position to the positioning position, the transmission rod 23 is always located in the second extension groove 412 and moves along the extension direction of the second extension groove 412. In this way, after the positioning plate 22 has completed its rotation, it can still move a distance synchronously with the slider 21. Compared with the scheme that only sets the first extension groove 411, it can ensure that the positioning plate 22 has completed its rotation when it abuts against the side wall of the battery cell 100, and can adapt to battery cells 100 of different sizes and placement positions.
[0043] Continue to refer to Figures 1-4 The positioning plate 22 is fixedly connected to a shaft 24, the axis of which is the rotation center of the positioning plate 22 relative to the slider 21. This means the transmission rod 23 can rotate relative to the axis of the shaft 24 under the guidance of the first extension groove 411. Furthermore, the shaft 24 and the transmission rod 23 are fixedly connected, and their axes are parallel and spaced apart. The slider 21 is connected to a bearing 25, and the shaft 24 is located within the inner ring of the bearing 25, thereby enabling the shaft 24 and the positioning plate 22 to rotate stably relative to the slider 21.
[0044] As an alternative, the guide plate 4 can be replaced with a motor that can drive the positioning plate 22 to rotate relative to the slider 21, achieving the same effect.
[0045] Continue to refer to Figures 1-4 The driving component 3 includes a fixed end and a telescopic end that can reciprocate relative to the fixed end. The fixed end is connected to the support base 1, and the telescopic end is connected to the slider 21. Thus, the reciprocating extension and retraction of the telescopic end relative to the fixed end can drive the slider 21 to reciprocate relative to the support base 1.
[0046] Continue to refer to Figures 1-4 The surface of the positioning plate 22 is provided with a rubber pad 221 to provide cushioning and reduce the impact force of the positioning plate 22 on the side wall of the battery cell 100 when the positioning plate 22 comes into contact with the battery cell 100, so as to avoid damage to the outer shell of the battery cell 100.
[0047] Continue to refer to Figures 1-4The support base 1 is provided with a slide rail 11, and the slider 21 slides in cooperation with the slide rail 11 so that the slider 21 can slide smoothly relative to the support base 1. In addition, the slide rail 11 can be an I-beam rail, and the slider 21 fits against the I-beam rail, thereby preventing the slider 21 from disengaging from the slide rail 11 and allowing it to slide only along the extension direction of the slide rail 11.
[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
