An abutting plate is movably connected to the end of the second connecting plate away from the first connecting plate via a second rotating shaft. The top of the abutting plate penetrates the battery box and extends into the interior of the cover plate.

[0009] As a preferred embodiment of the present invention, a first reset spring is sleeved on the front side of the guide post surface, the front side of the first reset spring is fixedly connected to the rear side of the limiting block, and the rear side of the first reset spring is fixedly connected to the front side of the limiting plate.

[0010] As a preferred embodiment of the present invention, limit rings are provided on both sides of the first connecting plate, the inner ring of the limit ring is fixedly connected to the surface of the fixing post, the surface of the limit ring is used in conjunction with the surface of the first connecting plate, and the top of the guide post is provided with a locking groove for use with the locking plate.

[0011] As a preferred embodiment of the present invention, the abutting plate is provided with a guide rod inside, the front and rear sides of the guide rod are fixedly connected to the inner wall of the battery box, the abutting plate is provided with a first opening for use with the guide rod, and a second return spring is fixedly connected to the top of the guide rod, the top of the second return spring is fixedly connected to the top of the inner wall of the first opening.

[0012] As a preferred embodiment of the present invention, a second opening is provided on the rear side inside the cover plate for use with a retaining plate. The top of the retaining plate is angled, and the surface of the retaining plate is movably connected to the inside of the battery box.

[0014] As a preferred embodiment of the present invention, the method of use includes the following steps:

[0015] Step S1: When it is necessary to open the cover, press down on the abutment plate to disengage it from the inside of the cover.

[0016] Step S2: Simultaneously, the abutting plate moves the second connecting plate through the second rotating shaft, and the second connecting plate moves the first connecting plate through the first rotating shaft, causing the first connecting plate to rotate around the fixed column. The first connecting plate moves the locking plate, causing the locking plate to disengage from the surface of the guide rod.

[0017] Step S3: Pull the cover plate backward. The cover plate moves backward through the hinge, causing the fixing plate and guide rod to move backward. The cover plate causes the locking block to disengage from the inside of the locking slot, thereby opening the cover plate.

[0018] Step S4: When it is necessary to close, the cover plate drives the locking block to engage in the slot. At the same time, when the locking plate is flush with the second opening, the second reset spring rebounds and pushes the locking plate, causing the locking plate to engage with the cover plate. The locking plate engages with the guide rod, and the locking is completed simultaneously.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This invention, by setting a guiding telescopic structure and a locking structure, can guide the cover plate through the telescopic structure to prevent it from falling out of the battery box. The locking structure can fix the cover plate and the guiding telescopic structure at the same time. The double-layer fixation achieves a stable fixation. This solves the problem that existing anti-leakage battery boxes are prone to separation of the battery box, battery and cover plate when impacted or dropped during use. The separated battery and cover plate are easy to fall into corners and are difficult to find. At the same time, frequent opening and closing of the cover plate can easily cause it to loosen, making it impossible to lock the battery in place and causing the battery to fall out.

[0021] 2. By setting a guide telescopic structure, the present invention can move the cover plate by pulling it, and the cover plate moves the fixed plate. The fixed plate moves the guide column, which moves inside the limiting plate, thus limiting the cover plate and preventing it from falling off the battery box.

[0022] 3. By setting a locking structure, the present invention can move the abutting plate by pushing it against the guide post. The abutting plate moves the second connecting plate downward through the second rotating shaft. The second connecting plate moves the first connecting plate through the first rotating shaft. The first connecting plate rotates around the fixed post, causing the first connecting plate to move the locking plate. The locking plate locks onto and moves away from the guide post, thus achieving locking and movement. At the same time, the abutting plate can lock the cover plate, providing secondary fixation for the cover plate and making the fixation more stable.

[0023] 4. By setting a first reset spring, a limiting ring, and a locking groove, the present invention can facilitate the reset of the limiting block, thereby facilitating the movement of the guide post driven by the limiting block, and thus facilitating the reset of the fixed plate and the cover plate driven by the guide post. The limiting ring is set on both sides of the first connecting plate to limit the movement of the first connecting plate and prevent the structure from jamming. The locking groove is opened on the surface of the guide post, and the locking plate can limit the guide post, thereby fixing and limiting the cover plate.

[0024] 5. By setting a guide rod, a first opening, and a second reset spring, the present invention can limit and guide the abutting plate. The first opening facilitates the movement of the guide rod inside the abutting plate, and the second reset spring facilitates the reset of the abutting plate, thereby facilitating the abutting plate to be inserted into the cover plate and limiting and fixing the cover plate.

[0025] 6. By providing a second opening, anti-slip texture, locking block, and locking groove, this invention facilitates the insertion of the locking plate into the interior of the cover, limiting the position of the cover. Simultaneously, it allows the user to easily actuate the locking plate through the second opening, facilitating structural transmission. The anti-slip texture on the top of the cover facilitates movement, preventing the cover from being unable to open due to a smooth surface. The locking block and locking groove allow the cover to be locked in place, limiting and fixing the cover, increasing its stability, and thus enhancing the secure connection between the cover and the battery box.

[0033] To further understand the content, features, and effects of this invention, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0034] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides a cover locking device and method for a leakage-proof battery box, including a battery box 1, a cover plate 2, a connecting wire 3, and a connector 4. The cover plate 2 is located on the top of the battery box 1 and is used in conjunction with the surface of the battery box 1. The front side of the battery box 1 is electrically connected to one end of the connecting wire 3, and the other end of the connecting wire 3 is electrically connected to the connector 4. A guide telescopic structure 5 is movably connected to the bottom of the rear side of the cover plate 2. The front side of the guide telescopic structure 5 penetrates the battery box 1 and extends into the interior of the battery box 1. The surface of the guide telescopic structure 5 is movably connected to the interior of the battery box 1. A locking structure 6 is provided on the top of the guide telescopic structure 5. The locking structure 6 is located on the rear side inside the battery box 1 and is used in conjunction with the surface of the guide telescopic structure 5. The top of the locking structure 6 penetrates the battery box 1 and extends into the interior of the cover plate 2.

[0036] refer to Figure 3 , Figure 4 and Figure 5 The guide telescopic structure 5 includes a fixed plate 501. The top of the fixed plate 501 is movably connected to the bottom of the rear side of the cover plate 2 via a hinge. Guide posts 502 are fixedly connected to both sides of the front side of the fixed plate 501. The front side of the guide post 502 penetrates the battery box 1 and extends into the interior of the battery box 1. A limiting plate 503 is sleeved on the surface of the guide post 502. The top and bottom of the limiting plate 503 are fixedly connected to the inner wall of the battery box 1. A limiting block 504 is fixedly connected to the front side of the guide post 502. The rear side of the limiting block 504 cooperates with the front side of the limiting plate 503. The locking structure 6 is located at the top of the guide post 502 and cooperates with the surface of the guide post 502.

[0037] The above solution is adopted: by setting the guide telescopic structure 5, the cover plate 2 can be pulled, the cover plate 2 can drive the fixed plate 501 to move, the fixed plate 501 can drive the guide column 502 to move, and the guide column 502 can move inside the limiting plate 503, which can limit the cover plate 2 and prevent the cover plate 2 from falling off the battery box 1.

[0038] refer to Figure 3 , Figure 4 and Figure 5 The locking structure 6 includes a locking plate 601. The bottom of the locking plate 601 contacts the top of the guide post 502. A first connecting plate 602 is fixedly connected to the top of the locking plate 601. A fixing post 603 is provided inside the first connecting plate 602. Both sides of the fixing post 603 are fixedly connected to the inner wall of the battery box 1. The surface of the fixing post 603 is movably connected to the inside of the first connecting plate 602. A second connecting plate 604 is movably connected to the top of the first connecting plate 602 through a first rotating shaft. An abutting plate 605 is movably connected to the end of the second connecting plate 604 away from the first connecting plate 602 through a second rotating shaft. The top of the abutting plate 605 penetrates the battery box 1 and extends into the interior of the cover plate 2.

[0039] The above solution is adopted: by setting the locking structure 6, the abutting plate 605 can be abutted, and the abutting plate 605 drives the second connecting plate 604 to move downward through the second rotating shaft. The second connecting plate 604 drives the first connecting plate 602 to move through the first rotating shaft. The first connecting plate 602 rotates around the fixed column 603, so that the first connecting plate 602 drives the locking plate 601 to move. The locking plate 601 is locked and moved by locking onto and away from the guide column 502. At the same time, the abutting plate 605 can lock the cover plate 2 and fix the cover plate 2 a second time, making the fixation more stable.

[0040] refer to Figure 3 , Figure 4 and Figure 5 A first reset spring 7 is sleeved on the front side of the guide post 502. The front side of the first reset spring 7 is fixedly connected to the rear side of the limiting block 504, and the rear side of the first reset spring 7 is fixedly connected to the front side of the limiting plate 503.

[0041] The above solution is adopted: by setting the first reset spring 7, the limit block 504 can be easily reset, thereby facilitating the limit block 504 to drive the guide post 502 to move, thereby facilitating the guide post 502 to drive the fixed plate 501 and the cover plate 2 to reset.

[0042] refer to Figure 3 , Figure 4 and Figure 5Limiting rings 8 are provided on both sides of the first connecting plate 602. The inner ring of the limiting ring 8 is fixedly connected to the surface of the fixing post 603. The surface of the limiting ring 8 is used in conjunction with the surface of the first connecting plate 602. The top of the guide post 502 is provided with a locking groove 9 that is used in conjunction with the locking plate 601.

[0043] The above solution is adopted: the limiting rings 8 are set on both sides of the first connecting plate 602, which can limit the movement of the first connecting plate 602 and thus prevent the structure from jamming. The locking groove 9 is opened on the surface of the guide post 502, which can limit the guide post 502 through the locking plate 601, thereby fixing and limiting the cover plate 2.

[0044] refer to Figure 3 , Figure 4 and Figure 5 The abutting plate 605 is provided with a guide rod 10 inside. The front and rear sides of the guide rod 10 are fixedly connected to the inner wall of the battery box 1. The abutting plate 605 is provided with a first opening 11 that works with the guide rod 10. A second return spring 12 is fixedly connected to the top of the guide rod 10. The top of the second return spring 12 is fixedly connected to the top of the inner wall of the first opening 11.

[0045] By adopting the above scheme, by setting the guide rod 10, the first opening 11 and the second return spring 12, the abutting plate 605 can be limited and guided. The first opening 11 can facilitate the movement of the guide rod 10 inside the abutting plate 605, and the second return spring 12 can facilitate the reset of the abutting plate 605, thereby facilitating the abutting plate 605 to be inserted into the cover plate 2 and limiting and fixing the cover plate 2.

[0046] refer to Figure 1 and Figure 5 The rear side of the cover plate 2 is provided with a second opening 13 for use with the abutment plate 605. The top of the abutment plate 605 is angled, and the surface of the abutment plate 605 is movably connected to the inside of the battery box 1.

[0047] The above solution allows the abutting plate 605 to be easily inserted into the cover plate 2 by setting the second opening 13, thus limiting the cover plate 2. At the same time, it also allows the user to easily abut the abutting plate 605 through the second opening 13, facilitating the transmission of the structure.

[0048] refer to Figure 1 , Figure 2 and Figure 6 The front and rear sides of the top of the cover plate 2 are provided with anti-slip textures. The front side of the cover plate 2 is fixedly connected with a card block 14. The inside of the battery box 1 is provided with a card slot 15 that works with the card block 14.

[0049] The above solution is adopted: the anti-slip texture is formed on the top of the cover plate 2, which makes it easy to move the cover plate 2 and avoids the problem of the cover plate 2 being unable to be opened due to its smooth surface. Through the locking block 14 and the locking groove 15, the locking block 14 on the cover plate 2 can be locked into the locking groove 15 to limit and fix the cover plate 2, increase the stability of the cover plate 2, and thus increase the stability of the connection between the cover plate 2 and the battery box 1.

[0050] Working principle of the invention:

[0051] When in use, if the user needs to open the cover plate 2, they press the abutment plate 605 through the second opening 13. The abutment plate 605 is guided by the guide rod 10 and simultaneously compresses the second return spring 12. The abutment plate 605 drives the second connecting plate 604 to move via the second rotating shaft. The second connecting plate 604 drives the first connecting plate 602 to move via the first rotating shaft. The first connecting plate 602 rotates around the fixed post 603, causing the first connecting plate 602 to drive the locking plate 601 to rotate around the fixed post 603. Simultaneously, when the locking plate 601 disengages from the guide post 502, the cover plate 2 moves backward. The cover plate 2, via a hinge, moves the fixing plate 501 backward. The fixing plate 501 then moves the guide post 502 backward. The guide post 502 causes the limiting block 504 to press the first return spring 7, causing the first return spring 7 to retract. At the same time, the cover plate 2 moves the locking block 14 out of the slot 15. When the locking block 14 disengages from the slot 15, the battery compartment 1 can be opened to remove and insert the battery. After the operation is completed, the cover plate 2 is placed back on the battery compartment. When the surface of plate 1 is pushed forward, the first return spring 7 rebounds and the limiting block 504 moves forward. The limiting block 504 drives the guide post 502 to move forward, and the guide post 502 drives the fixing plate 501 to move forward. This causes the fixing plate 501 to drive the cover plate 2 to move forward through the hinge. The cover plate 2 drives the locking block 14 to engage in the slot 15. At the same time, when the second opening 13 is parallel to the abutting plate 605, the second return spring 12 rebounds and abuts the locking plate 605, causing the abutting plate 605 to engage in the second opening 13 of the cover plate 2 for initial fixing. The abutting plate 605 drives the second connecting plate 604 to move via the second rotating shaft. The second connecting plate 604 drives the first connecting plate 602 to move via the first rotating shaft. The first connecting plate 602 rotates around the fixed post 603, causing the locking plate 601 to engage in the locking groove 9 of the guide post 502, thereby limiting and fixing the guide post 502. Because the cover plate 2 is connected to the fixed plate 501 and the guide post 502, it also limits the cover plate 2, achieving the purpose of secondary fixing and better locking.

[0052] In summary, the cover locking device and its usage method for this anti-leakage battery box, through the coordinated use of the battery box 1, cover 2, connecting wire 3, connector 4, guide telescopic structure 5, fixing plate 501, guide post 502, limiting plate 503, limiting block 504, locking structure 6, locking plate 601, first connecting plate 602, fixing post 603, second connecting plate 604, abutting plate 605, first return spring 7, limiting ring 8, locking groove 9, guide rod 10, first opening 11, second return spring 12, second opening 13, locking block 14, and locking groove 15, solves the problem that existing anti-leakage battery boxes, when impacted or dropped, cause the battery box, battery, and cover to separate. The separated battery and cover are easily dropped into corners and difficult to find. Furthermore, frequent opening and closing of the cover can easily cause it to loosen, making it impossible to secure the battery, leading to battery detachment.

The second connecting plate (604) drives the first connecting plate (602) to move through the first rotating shaft, so that the first connecting plate (602) rotates around the fixed column (603). The first connecting plate (602) drives the locking plate (601) to move, so that the locking plate (601) disengages from the surface of the guide rod (10). Step S3: Pull the cover plate (2) backward. The cover plate (2) moves backward through the hinge, causing the fixing plate (501) and guide rod (10) to move backward. The cover plate (2) causes the locking block (14) to disengage from the inside of the slot (15), thereby opening the cover plate (2). Step S4: When it is necessary to close, the cover plate (2) drives the locking block (14) to be inserted into the slot (15). At the same time, when the locking plate (605) is flush with the second opening (13), the second reset spring (12) rebounds and pushes the locking plate (605), so that the locking plate (605) is inserted into the cover plate (2), and the locking plate (601) is inserted into the guide rod (10), thus completing the locking simultaneously.
