Description

Technical Field

[0001] This utility model relates to a lithium battery packaging box, specifically a lithium battery packaging box with a self-opening cover. Background Technology

[0002] Lithium battery packaging boxes provide physical protection for the batteries, preventing mechanical damage such as external impacts and compression. The boxes are typically made of high-strength materials, capable of withstanding certain external forces and protecting the batteries from damage.

[0003] The lithium battery assembly process is as follows: First, open the packaging box; then, install the lithium battery into the packaging box; next, secure the battery using battery clamps; finally, close the packaging box. Typically, to prevent damage to the lithium battery during use (water ingress, battery puncture, impact causing poor contact, etc.), the separation of the packaging box body and cover is very difficult, thus protecting the lithium battery. Commonly, the packaging box body and cover are connected by screws.

[0004] Generally, more screws result in a tighter and more secure connection between the cover and the enclosure; however, this reduces installation efficiency and increases the difficulty of disassembly during maintenance. Conversely, fewer screws increase installation efficiency and reduce the difficulty of disassembly during maintenance, but the connection between the cover and the enclosure is unreliable. Therefore, using screws to connect the cover and the enclosure is not conducive to improving installation efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a lithium battery packaging box with a self-opening cover to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0012] The slider can slide into the box when the cover closes the box; and the locking structure can restrict the opening structure's operation after the cover closes the box.

[0013] When the locking structure releases its restriction on the opening structure, the slider can slide out of the housing to move the cover, thereby separating the cover from the housing.

[0014] The lithium battery packaging box with a self-opening cover as described above: the opening structure includes a telescopic sleeve installed inside the box body, and a telescopic column fixedly connected to the slider is slidably fitted inside the telescopic sleeve; a first spring is provided inside the telescopic sleeve; the two ends of the first spring respectively abut against the telescopic column and the telescopic sleeve.

[0016] The lithium battery packaging box with a self-opening cover as described above: the side of the wedge near the cover is set as a slope.

[0017] The lithium battery packaging box with a self-opening cover as described above: a rotating block is rotatably mounted on the end of the slide bar away from the wedge; the rotating block is flat near the protruding sleeve; and an arc block is mounted on the rotating block.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0042] Please see Figures 1-7 As an embodiment of the present utility model, the self-opening lithium battery packaging box includes a box body 1;

[0043] The box 1 is provided with a cover 2 and a gasket 3;

[0044] The gasket 3 is used to increase the sealing between the box body 1 and the cover 2;

[0045] The housing 1 is equipped with an opening structure and a locking structure;

[0046] The opening structure includes a slider 4 that is rotatably connected to the cover 2 and slidably connected to the housing 1;

[0047] The slider 4 can slide into the box 1 when the cover 2 closes the box 1; and the locking structure can restrict the opening structure's operation after the cover 2 closes the box 1.

[0048] When the locking structure releases its restriction on the opening structure, the slider 4 can slide out of the housing 1 to move the cover 2, thereby separating the cover 2 from the housing 1.

[0049] In this embodiment, the packaging box is in the fully open state: the cover 2 is perpendicular to the ground of the box body 1, and the cover 2 is located on one side of the box body 1. The packaging box is in the fully closed state: the cover 2 is parallel to the bottom surface of the box body 1, and the gasket 3 is in a compressed state (the cover 2 squeezes the gasket 3).

[0050] Packaging box opening process: Apply external force to release the locking structure from the opening structure; slider 4 will move away from the bottom surface of box 1, thereby driving the cover 2 to move away from the bottom surface of box 1, so that the cover 2 is separated from box 1, and the gasket 3 elastically resets; apply external force to flip the cover 2 (the cover 2 changes from a state parallel to the bottom surface of box 1 to a state perpendicular to the bottom surface of box 1) to fully open the packaging box, so as to facilitate battery assembly or repair.

[0051] Packaging box closing process: After the internal components of the packaging box are installed or repaired, flip the cover 2 (the cover 2 changes from a state perpendicular to the bottom surface of the box 1 to a state parallel to the bottom surface of the box 1); and after the flipping is completed, apply external force to press the cover 2, so that the cover 2 moves closer to the bottom surface of the box 1, thereby driving the slider 4 to move synchronously; when the slider 4 moves to the end of its stroke, the locking structure will be activated to restrict the movement of the slider 4, thereby restricting the movement of the cover 2; at this time, the rotation center of the cover 2 and the slider 4 is located inside the box 1, and the cover 2 will not be able to flip under the resistance of the box 1.

[0052] At the same time, the cover 2 will compress the gasket 3, so that the gasket 3 can be elastically deformed, thereby improving the sealing between the box 1 and the cover 2.

[0053] By restricting the opening mechanism through the locking structure, the packaging box can be prevented from being loosely sealed or accidentally opened, thus protecting the environment for the normal operation of the battery inside the packaging box. Through the cooperation between the locking and opening mechanisms, the opening and closing of the packaging box can be achieved relatively easily, thereby improving the efficiency of installation or maintenance.

[0054] As a further embodiment of this utility model, the opening structure includes a telescopic sleeve 101 installed inside the housing 1, and a telescopic column 5 fixedly connected to the slider 4 is slidably fitted inside the telescopic sleeve 101; a first spring 8 is provided inside the telescopic sleeve 101; the two ends of the first spring 8 respectively abut against the telescopic column 5 and the telescopic sleeve 101.

[0055] In this embodiment, when the packaging box is in the closed state: the first spring 8 is in the compressed state; at this time, the elastic force of the first spring 8 will act on the telescopic column 5, so that the telescopic column 5 has a tendency to slide outward within the telescopic sleeve 101; the locking structure restricts the displacement of the slider 4, thereby counteracting the tendency of the telescopic column 5 to move; in this state, the cover 2 squeezes the gasket 3, and the gasket 3 will be elastically deformed under the support of the box body 1, and the rotation center of the cover 2 and the slider 4 is located inside the box body 1.

[0056] When the locking structure releases the restriction on the slider 4, the elastic force of the first spring 8 will cause the telescopic column 5 to slide outward within the telescopic sleeve 101, thereby causing the slider 4 to move synchronously, so as to separate the cover 2 from the box body 1, and the rotation center of the cover 2 and the slider 4 will gradually rise. When the slider 4 moves to the forming end, an external force is applied to flip the cover 2 to fully open the packaging box.

[0057] By combining the locking and opening mechanisms, the packaging box can be opened and closed relatively easily, thereby improving the convenience of installation or maintenance.

[0058] As a further embodiment of this utility model, the locking structure includes a fixing block 6 installed on the faceplate 2; both the fixing block 6 and the slider 4 have limiting grooves 7; multiple sets of protruding sleeves 9 are installed on the housing 1, and wedges 10 that cooperate with the limiting grooves 7 are slidably fitted inside the protruding sleeves 9; a sliding rod 11 is installed on the wedges 10; a second spring 12 is wrapped around the sliding rod 11; the two ends of the second spring 12 respectively abut against the wedges 10 and the protruding sleeves 9.

[0059] In this embodiment, the packaging box closing process is as follows: flip the cover 2 so that the cover 2 is parallel to the bottom surface of the box body 1 (the fixing block 6 moves synchronously with the cover 2, and when the cover 2 is parallel, the fixing block 6 is perpendicular to the bottom surface of the box body 1), apply external force to press the cover 2 so that the cover 2 moves closer to the bottom surface of the box body 1, at which time the slider 4 moves synchronously with the fixing block 6; the first spring 8 is compressed.

[0060] During the movement of slider 4 and fixed block 6, limit groove 7 moves synchronously.

[0061] The slider 4 and the fixed block 6 will first contact the wedge 10, and after contact, they will squeeze the wedge 10 so that the wedge 10 moves inward in the protruding sleeve 9 to compress the second spring 12 and drive the slide rod 11 to move synchronously.

[0062] When the limiting groove 7 is aligned with the wedge 10, the slider 4 and the fixing block 6 will no longer press the wedge 10. At this time, under the elastic force of the second spring 12, the wedge 10 will move outward in the protruding sleeve 9 to enter the limiting groove 7. Through the mutual pressing of the limiting groove 7 and the wedge 10, the displacement of the fixing block 6 and the slider 4 can be restricted, thereby restricting the movement of the cover 2.

[0063] During the release process, an external force is applied to move the slide bar 11 within the protruding sleeve 9, thereby causing the wedge block 10 to move inward within the protruding sleeve 9, thus separating the wedge block 10 from the limiting groove 7. With the wedge block 10 no longer pressing against the limiting groove 7, the slider 4 moves upward under the elastic force of the first spring 8, thereby causing the faceplate 2 and the fixing block 6 to move synchronously.

[0064] By restricting the opening mechanism through the locking structure, the packaging box can be prevented from being loosely sealed or accidentally opened, thus protecting the environment for the normal operation of the battery inside the packaging box. The cooperation between the locking and opening mechanisms makes it easier to open and close the packaging box, thereby improving the convenience of installation or maintenance.

[0065] As a further embodiment of this invention, the side of the wedge block 10 closest to the cover 2 is configured as a slope 1001.

[0066] In this embodiment, when the fixing block 6 and the slider 4 come into contact with the slope 1001, the force of the fixing block 6 and the slider 4 moving downward will be transformed by the slope 1001 into a force that causes the wedge 10 to move within the protruding sleeve 9; thereby preventing the wedge 10 from obstructing the movement of the slider 4, thus reducing the resistance to closing the packaging box.

[0067] As a further embodiment of this utility model, a rotating block 13 is rotatably mounted on the end of the slide rod 11 away from the wedge block 10; the rotating block 13 is a plane 1301 near the protruding sleeve 9; and an arc block 1302 is mounted on the rotating block 13.

[0068] In this embodiment, when the packaging box is in a closed state, the plane 1301 abuts against the protruding sleeve 9, and at this time the distance between the rotation center of the rotating block 13 and the protruding sleeve 9 is the first gap.

[0069] An external force is applied to rotate the rotating block 13. The distance between the apex of the arc block 1302 and the rotation center of the rotating block 13 is the second distance, which is greater than the first distance. Therefore, when the rotating block 13 rotates, the plane 1301 separates from the protruding sleeve 9; while the arc block 1302 abuts against the protruding sleeve 9. At this time, under the action of the arc block 1302 and the protruding sleeve 9, the rotation center of the rotating block 13 will gradually move away from the protruding sleeve 9, thereby driving the slide rod 11 to move, so as to drive the wedge block 10 to move inward within the protruding sleeve 9, compressing the second spring 12. At this time, the wedge block 10 separates from the limiting groove 7. That is, the locking structure releases the restriction on the slider 4.

[0070] The rotating block 13 reduces the difficulty of opening the packaging box, thereby improving installation efficiency.

[0071] As a further improvement of this invention, the gasket 3 is elastic.

[0072] In this embodiment, during the closing process, the cover 2 will squeeze the gasket 3. Under the action of the squeezing force, the gasket 3 will undergo elastic deformation, thereby improving the sealing performance of the packaging box in the closed state.

[0073] After the packaging box is opened, the gasket 3 will return to its original position due to its own elasticity, so as to prevent the packaging box from being damaged when it is closed again.

[0074] As a further embodiment of this utility model, a protective block 102 for protecting the rotating block 13 is installed on the housing 1.

[0075] In this embodiment, the protective block 102 can prevent the rotating block 13 from rotating unnecessarily, such as due to accidental collisions during use; thereby ensuring that the working environment of the battery is not damaged.

[0076] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
