Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to cell buffer mechanisms. Background Technology

[0002] In the screen printing process, solar cells require a buffer function after printing and drying. To avoid scratching the cells, existing buffer boxes often use support units to support the cells in a line contact manner. However, this method has low adaptability when dealing with cells of different sizes. Utility Model Content

[0003] Therefore, it is necessary to provide a battery cell buffering mechanism to address the problem of low adaptability of existing buffer boxes when dealing with battery cells of different sizes.

[0004] A battery cell buffer mechanism, comprising:

[0005] A mounting bracket, wherein the mounting bracket is provided with at least one mounting portion extending in a first direction;

[0006] The support unit includes at least one, with each support unit arranged in at least one column, and each support unit is used to support a battery cell; each support unit includes at least two support members, each support member is mounted on a corresponding mounting portion and is movable relative to the mounting portion along the first direction, and each support member is used to contact the corresponding battery cell line for support.

[0007] In one embodiment, the mounting frame is provided with a mounting hole, the support member passes through the mounting hole and is connected to the mounting frame, and the mounting hole is configured as the mounting part.

[0008] In one embodiment, the support includes a support rod and a fastener. The support rod supports the battery cell, and the fastener passes through the mounting hole and is slidable relative to the hole wall along the first direction. The fastener is detachably connected to the support rod to fix the support rod to the mounting bracket.

[0009] In one embodiment, the fastener has a protrusion at one end away from the corresponding support rod, and the protrusion and the corresponding support rod are used to clamp the fixing frame.

[0010] In one embodiment, the support rod is cylindrical.

[0011] In one embodiment, the outer side of the support rod is fitted with a silicone sleeve.

[0012] In one embodiment, the fixing frame includes at least one connecting plate and at least one support group, each support group including two support plates spaced apart along a second direction, at least one end of each support plate being connected to the connecting plate, wherein the second direction is perpendicular to the first direction;

[0013] Each of the support plates is provided with the mounting part, each of the support units includes at least three support members, and the support members of each support unit are respectively mounted on two of the support plates in a support group.

[0014] In one embodiment, each of the support plates is movable relative to the connecting plate in the second direction.

[0015] In one embodiment, the connecting plate is provided with an adjustment hole extending along the second direction, and the fixing frame further includes an adjustment member, which passes through the adjustment hole and is slidable relative to the hole wall of the adjustment hole along the second direction. The adjustment member is detachably connected to the support plate so that the support plate is connected to the connecting plate.

[0016] In one embodiment, the battery cell buffer mechanism further includes at least one storage box having a storage slot. The storage box is located below the fixing frame and is slidably connected to the fixing frame along the first direction. The opening of the storage slot is located on the side facing the support unit.

[0017] Beneficial effects:

[0018] The battery cell buffer mechanism provided in this application includes a fixing frame and a support unit. The fixing frame has at least one mounting portion extending along a first direction. At least one support unit is provided, arranged in at least one row, and each support unit supports one battery cell. Each support unit includes at least two support members, each support member is mounted on a corresponding mounting portion and is movable relative to the mounting portion along the first direction. Each support member is used to make line contact with the corresponding battery cell for support. In this application, the support members make line contact with the battery cell, reducing the contact area between the battery cell and the support unit. This reduces the risk of scratches and dust accumulation on the battery cell surface caused by the support units. Furthermore, the ability of each support member to move relative to the extension direction of the mounting portion allows adjustment of the position of the support members in each support unit, adapting the position of the support members in each support unit to the size of the battery cell. This provides stable support for each battery cell, improving the stability of the battery cell support and the adaptability of the battery cell buffer mechanism.

[0019] Since the mounting part extends along the first direction, multiple support members can be installed in the mounting part. That is, the number of support members installed in each mounting part is unlimited. Therefore, the number of support members can be increased or decreased according to the different weights of the battery cells, so as to ensure stable support of the battery cells and reduce scratches on the surface of the battery cells.

Detailed Implementation

[0024] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0025] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0026] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0029] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0030] See Figure 1 , Figure 1 A schematic diagram of a battery cell buffer mechanism provided in an embodiment of this application. Figure 1An embodiment of this application provides a battery cell buffer mechanism, including a fixing frame 100 and a support unit 200. The fixing frame 100 is provided with at least one mounting portion extending along a first direction; the support unit 200 is provided with at least one, and each support unit 200 is arranged in at least one row, and each support unit 200 is used to support a battery cell; each support unit 200 includes at least two support members 210, each support member 210 is mounted on a corresponding mounting portion and is movable relative to the mounting portion along the first direction, and each support member 210 is used to contact the corresponding battery cell line for support.

[0031] Specifically, in this application, the support member 210 makes line contact with the battery cell, thereby reducing the contact area between the battery cell and the support unit 200. This reduces the risk of scratches, dust accumulation, and other adverse effects on the surface of the battery cell caused by each support unit 200. Furthermore, since each support member 210 can move relative to the extension direction of the mounting part, the position of the support member 210 in each support unit 200 can be adjusted so that the position of the support member 210 in each support unit 200 is adapted to the size of the battery cell, thereby stably supporting each battery cell and improving the stability of the battery cell and the adaptability of the battery cell buffer mechanism.

[0032] Since the mounting part extends along the first direction, multiple support members 210 can be installed in the mounting part. That is, the number of support members 210 installed in each mounting part is not limited. Therefore, the number of support members 210 can be increased or decreased according to the different weights of the battery cells, so as to ensure stable support of the battery cells and reduce scratches on the surface of the battery cells.

[0033] Furthermore, in this application, the first direction is parallel to the horizontal direction, thereby ensuring that the support member 210 can stably support the battery cell during movement along the first direction. Preferably, the support member 210 extends along the horizontal direction.

[0034] It should be noted that the instruction manual is attached. Figure 1 Taking this example, we define XX' as the first direction, YY' as the second direction, and ZZ' as the third direction. The first, second, and third directions are all perpendicular to each other, and the third direction is parallel to the direction of gravity. For ease of description, we will use the first, second, and third directions in the following descriptions.

[0035] See Figure 1 In one embodiment, the mounting bracket 100 is provided with a mounting hole 110, the support member 210 passes through the mounting hole 110 and is connected to the mounting bracket 100, and the mounting hole 110 is configured as a mounting part.

[0036] Specifically, the mounting hole 110 simplifies the structure of the mounting section, facilitates its fabrication, and reduces the processing cost of the battery cell buffer mechanism. In other embodiments, the mounting section can also be a mounting groove.

[0037] See Figure 1 In one embodiment, the support member 210 includes a support rod 211 and a fastener 212. The support rod 211 is used to support the battery cell. The fastener 212 passes through the mounting hole 110 and can slide relative to the hole wall of the mounting hole 110 in a first direction. The fastener 212 is detachably connected to the support rod 211 to fix the support rod 211 to the mounting bracket 100.

[0038] Specifically, the support rod 211 is in contact with the battery cell line. Due to the detachable connection between the fastener 212 and the support rod 211, the fastener 212 can be separated from the support rod 211 when the support member 210 is installed and removed from the mounting hole 110. This facilitates the installation and removal of the support member 210 and the adjustment of its position, thereby improving the installation efficiency of the battery cell buffer mechanism and the efficiency of the position adjustment of the support member 210.

[0039] Furthermore, the fastener 212 abuts against the wall of the mounting hole 110, thereby reducing the wobbling of the fastener 212 relative to the fixing bracket 100 and improving the support stability of the support member 210 for the battery cell.

[0040] See Figure 1 In one embodiment, the fastener 212 has a protrusion at one end away from the corresponding support rod 211. The protrusion and the corresponding support rod 211 are used to clamp the fixing frame 100, thereby limiting the fastener 212 and the support rod 211 in the arrangement direction, preventing the support member 210 from shaking, so that the support member 210 is stably connected to the fixing frame 100, and improving the support stability of the support member 210 for the battery cell.

[0041] Furthermore, the support rod 211 is provided with a threaded hole, and the fastener 212 is threadedly connected to the threaded hole. Preferably, the fastener 212 is a bolt.

[0042] See Figure 1 In one embodiment, the support rod 211 is cylindrical, so that the installation angle of the support rod 211 is not limited during the threaded connection between the support rod 211 and the fastener 212, so that the support rod 211 can maintain line contact with the battery cell in any posture.

[0043] See Figure 1 In one embodiment, a silicone sleeve is provided on the outer side of the support rod 211 to reduce the friction of the support rod 211 on the surface of the battery cell and improve reliability.

[0044] See Figure 1 and Figure 2 , Figure 2 A schematic diagram of a battery cell buffer mechanism provided in an embodiment of this application. Figure 2 In one embodiment, the fixing frame 100 includes at least one connecting plate 120 and at least one support group 130. At least one end of each support group 130 is connected to the connecting plate 120, and each support group 130 includes two support plates 131 spaced apart along a second direction, wherein the second direction is perpendicular to the first direction. Each support plate 131 is provided with a mounting part, and each support unit 200 includes at least three support members 210. The support members 210 of each support unit 200 are respectively mounted on two support plates 131 in a support group 130.

[0045] Specifically, each support unit 200 includes at least three support members 210. The support members 210 of each support unit 200 are respectively mounted on two support plates 131 in a support group 130. That is, in a support unit 200, there are two corresponding mounting holes 110 spaced apart along the second direction on the same horizontal line. At least one support member 210 is provided in one mounting hole 110, and at least two support members 210 are provided in the other mounting hole 110. This allows at least three ends of the battery cell to be stably supported by the support rods 211, thereby improving the support stability of the battery cell. At least one end of each support group 130 is connected by a connecting plate 120, which can improve the stability of each support plate 131. This allows the two support plates 131 in each support group 130 to stably support the support members 210, thereby improving the reliability of the battery cell buffer mechanism.

[0046] Furthermore, each support unit 200 includes at least four support members 210, and each of the two support plates 131 corresponding to each support unit 200 is provided with at least two support members 210, so that the battery cell can be stably supported around its perimeter. In other embodiments, each support unit 200 may also include multiple support members 210 to adapt to the size and weight of the battery cell.

[0047] Furthermore, there are at least two connecting plates 120, and both ends of each support plate 131 are connected to the connecting plate 120. In particular, both ends of each support plate 131 along a third direction are connected to the connecting plate 120, thereby avoiding interference with the insertion of the battery cell into the support unit 200.

[0048] See Figure 1 and Figure 2 In one embodiment, each support plate 131 is provided with a plurality of mounting holes 110 spaced apart along a third direction, which is parallel to the direction of gravity, thereby saving space while accommodating more battery cells.

[0049] Furthermore, there are multiple support groups 130, and at least one end of each support group 130 shares a connecting plate 120, thereby further improving the stability of the support plate 131.

[0050] See Figure 1 and Figure 2 In one embodiment, each support plate 131 is movable relative to the connecting plate 120 in a second direction, thereby adjusting the spacing between two support plates 131 in each support group 130 to accommodate solar cells of different sizes in the second direction, thereby improving the adaptability of the solar cell buffer mechanism.

[0051] See Figure 1 and Figure 2 In one embodiment, the connecting plate 120 is provided with an adjustment hole 121 extending in a second direction. The fixing bracket 100 also includes an adjustment member 150, which passes through the adjustment hole 121 and can slide relative to the hole wall of the adjustment hole 121 in the second direction. The adjustment member 150 is detachably connected to the support plate 131 so that the support plate 131 is connected to the connecting plate 120.

[0052] Specifically, since the adjusting member 150 is detachably connected to the support plate 131, when adjusting the position of the support plate 131, the adjusting member 150 and the support plate 131 can be separated, thereby facilitating the adjustment of the position of the support plate 131 and improving the efficiency of the adjustment of the position of the support plate 131.

[0053] Furthermore, the side of the adjusting member 150 away from the support plate 131 abuts against the connecting plate 120, thereby cooperating with the support plate 131 to clamp the connecting plate 120, so that the support plate 131 and the connecting plate 120 are stably connected.

[0054] Furthermore, the adjusting member 150 abuts against the wall of the adjusting hole 121, thereby reducing the wobbling of the adjusting member 150 relative to the connecting plate 120 and improving the stability of the connection between the support plate 131 and the connecting plate 120. The adjusting member 150 is threadedly connected to the support plate 131. Preferably, the adjusting member 150 is a bolt.

[0055] See Figure 1 and Figure 2 In one embodiment, the connecting plate 120 is provided with an adjustment groove 140, which communicates with the adjustment hole 121. The end of the adjusting member 150 away from the support plate 131 is accommodated in the adjustment groove 140, thereby preventing the adjusting member 150 from protruding from the connecting plate 120 and preventing external parts from scratching the adjusting member 150, so as to affect the position of the support plate 131 relative to the connecting plate 120, and improving the reliability and aesthetics of the battery cell buffer mechanism.

[0056] See Figure 1and Figure 2 The battery cell buffer mechanism also includes at least one storage box 300, which has a storage slot 310. The storage box 300 is located below the fixing frame 100 and is slidably connected to the fixing frame 100 in a first direction. The slot of the storage slot 310 is located on the side facing the support unit 200.

[0057] Specifically, the storage box 300 is slidably connected to the connecting plate 120 located below it in a first direction. Since the battery cells and the support rod 211 are in line contact, the battery cell fragments in the battery cell buffer mechanism will automatically fall downward into the storage slot 310 of the storage box 300. The storage box 300 is slidably connected to the connecting plate 120 located below it, which facilitates the removal of the storage box 300 to clean up the battery cell fragments inside the storage box 300 and prevent the battery cell fragments from affecting the external environment.

[0058] Furthermore, the connecting plate 120 located below is provided with a groove 122, and the groove 122 is provided with an opening 123. The storage box 300 extends into the groove 122 through the opening 123, and corresponds with the support unit 200 through the slot of the groove 122, so that the battery cell fragments in the battery cell buffer mechanism will automatically fall downward through the slot of the groove 122 into the storage slot 310 of the storage box 300. The storage box 300 is also provided with a handle 320 on the outside of the groove 122, so as to facilitate the extension of the storage box 300 by controlling the handle 320.

[0059] Furthermore, a boss 124 protrudes from the side of the lower connecting plate 120 away from the support unit, and a groove 122 extends onto the boss 124. The presence of the boss 124 reduces the volume of the lower connecting plate 120, thereby reducing the weight of the cell buffer mechanism and making the cell buffer mechanism lighter.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
