[0037] This application provides a lock box. The lock box includes a box body, a box cover, and an elastomer. The box body is used to accommodate a battery holder. The box cover is slidably connected to the box body in directions away from and towards the box body. A stop is protruding on the side of the box cover away from the box body, and the stop is used to stop against the vehicle frame. The elastomer is configured to be retractably accommodated between the box cover and the box body. When the box cover is pressed to slide towards the box body, the box cover moves the stop away from the vehicle frame until it disengages from the vehicle frame, and the elastomer is compressed.

[0038] The aforementioned lock box allows the box body to be housed on the battery holder, and a stop protruding from one side of the box cover is used to stop it on the vehicle frame. An elastic body is configured to be retractably housed between the box cover and the box body. The box cover is slidably connected to the box body in directions away from and towards the box body. Thus, the elastic body, housed between the box cover and the box body, exerts an elastic thrust on the box cover and the box body upon compression, forcing them to slide apart. When a force is applied to press the box cover, causing it to slide towards the box body, the box cover moves the stop away from the vehicle frame until it disengages from the frame. The elastic body then compresses, and the pressing... Unlocking is convenient; then, when the force of pressing the cover is removed, the elastic body, through its own compressed elastic force, pushes the cover and the stop piece away from the body to restore the cover and body to their original state before pressing. The elastic body constantly prevents the stop piece from being moved closer to the body by the lock box, which effectively ensures the stability of the stop piece on the vehicle and the structure is simple; in addition, the body is housed in the battery holder, so even if the lock box is not installed on the battery holder, the entire lock box is not exposed to the frame, which effectively ensures the aesthetics and thus improves the user experience.

[0039] To better understand the lock box of this application, the following further explanation is provided:

[0040] Please refer to the following: Figures 1 to 4 One embodiment of the lock box 10 includes a box body 100, a box cover 200, and an elastic body 400. The box body 100 is used to accommodate a battery holder. The box cover 200 is slidably connected to the box body 100 in directions away from and towards the box body 100. A stop 300 is protruding on the side of the box cover 200 away from the box body 100, and the stop 300 is used to stop against the vehicle frame. The elastic body 400 is configured to be retractably accommodated between the box cover 200 and the box body 100. When the box cover 200 is pressed to slide towards the box body 100, the box cover 200 moves the stop 300 away from the vehicle frame until it disengages from the vehicle frame, and the elastic body 400 is compressed.

[0041] The aforementioned lock box 10 allows the box body 100 to be housed on the battery holder, and a stop 300 protruding from one side of the box cover 200 is used to stop against the vehicle frame. An elastic body 400 is configured to be retractably housed between the box cover 200 and the box body 100. The box cover 200 is slidably connected to the box body 100 in directions away from and towards the box body 100. Thus, when the elastic body 400 is housed between the box cover 200 and the box body 100, the compression of the elastic body 400 exerts an elastic thrust on the box cover 200 and the box body 100, forcing the box cover 200 and the box body 100 to slide apart. When a force is applied to press the box cover 200, causing it to slide towards the box body 100, the box cover 200 drives the stop 300 to move away from the vehicle frame until it disengages. Upon removal from the frame, the elastic body 400 compresses, making unlocking convenient. Then, when the force applied to the cover 200 is removed, the elastic body 400, through its own elastic force after compression, pushes the cover 200, causing the stop 300 to move away from the body 100, restoring the original state of the cover 200 and body 100 before pressing. The elastic body constantly prevents the stop 300 from being moved closer to the body 100 by the lock box 10, effectively ensuring the stability of the stop 300 on the vehicle frame, and the structure is simple. Furthermore, since the body 100 is housed in the battery holder, even if the lock box 10 is not installed on the battery holder, the entire lock box 10 is not exposed to the frame, ensuring aesthetics and improving the user experience.

[0042] Please refer to the following: Figures 1 to 4 In one embodiment, the box body 100 is provided with a sliding clearance cavity 101, and the box cover 200 is partially disposed in the sliding clearance cavity 101 and slidably connected to the box body 100, which better ensures the effective sliding of the box cover 200 on the box body 100.

[0043] Please refer to the following: Figures 1 to 4In one embodiment, the lid 200 includes a lid body 210 and a limiting body 220 connected together, with the limiting body 220 at least partially located on the side of the lid body 210 near the box body 100. Further, a stop member 300 protrudes from the side of the lid body 210 away from the box body 100, and an elastic body 400 is located between the lid body 210 and the box body 100, with both ends of the elastic body 400 abutting against the lid body 210 and the box body 100 respectively. Furthermore, the elastic body 400 extends to allow the cover 210 to slide away from the box 100 until it is at least partially stopped by the limiting body 220 on the box 100. This ensures that the cover 210 is slidably connected to the box 100 by the limiting body 220. In particular, the elastic body 400, through its own compressed elastic force, pushes the cover 200 to move the stop 300 away from the box 100 until it is stopped by the limiting body 220 on the box 100. At this time, the elastic body 400 can still maintain a certain compression and elastic force, which can better ensure the locking stability of the stop 300 on the vehicle.

[0044] Please refer to the following: Figures 1 to 4 In one embodiment, the cover 210 partially passes through the box body 100 and is connected to the limiting body 220, so that the cover 210 slides away from the box body 100 until the side of the limiting body 220 near the box body 100 abuts against the box body 100. Furthermore, the cover 210 and the limiting body 220 are detachably connected, improving the ease of installation of the limiting body 220 and the cover 210 on the box body 100, and better ensuring the stopping stability of the limiting body 220 on the box body 100.

[0045] Please refer to the following: Figures 1 to 4 In one embodiment, the limiting body 220 partially passes through the box body 100 and is connected to the cover body 210, so that the cover body 210 slides away from the box body 100 until the side of the limiting body 220 near the box body 100 abuts against the box body 100. Furthermore, the cover body 210 and the limiting body 220 are detachably connected, improving the ease of installation of the limiting body 220 and the cover body 210 on the box body 100, and better ensuring the stopping stability of the limiting body 220 on the box body 100.

[0046] Please refer to the following: Figures 1 to 4 In one embodiment, the cover 210 is screwed to the limiting body 220. Furthermore, the limiting body 220 is a screw, which improves the connection reliability between the limiting body 220 and the cover 210, and ensures the ease of installation of the limiting body 220 and the cover 210 on the box 100.

[0047] Please refer to the following: Figures 1 to 4In one embodiment, a guide body 500 protrudes from the side of the lid 200 near the box body 100, and an elastic body 400 is sleeved on the guide body 500, with both ends of the elastic body 400 abutting against the lid 200 and the box body 100 respectively. Further, the cover 210 passes through the box body 100 via the guide body 500 and is connected to the limiting body 220. Further, the cover 210 is slidably connected to the box body 100 via the guide body 500. Further, the guide body 500 is disposed at the sliding clearance cavity 101 and is slidably connected to the box body 100. Further, there are three guide bodies 500; there are three elastic bodies 400, each corresponding to one of the three guide bodies 500. Further, there are three limiting bodies 220, each corresponding to one of the three guide bodies 500. Furthermore, the three guide bodies 500 are respectively located at the three vertices of the triangle, effectively improving the force balance when the lid 200 is pressed, improving the telescopic stability of the stop 300, and thus improving the smoothness and stability of opening the secondary lock. It should be noted that this application does not limit the number of guide bodies, limiting bodies, and elastic bodies, nor does it limit the relationship between guide bodies, limiting bodies, and elastic bodies to a one-to-one correspondence. That is, the number of guide bodies can be two or more, the number of elastic bodies can be one, and the number of limiting bodies can be only one. Guide bodies not corresponding to elastic bodies or limiting bodies may only serve as sliding guides. Furthermore, elastic bodies and limiting bodies are not necessarily only corresponding to one guide body. That is, when there are two guide bodies, the elastic body and limiting body are respectively corresponding to two guide bodies, which can also effectively achieve the functions of stopping and returning simultaneously. Furthermore, the end of the guide body 500 near the box body 100 is provided with a threaded hole, and the end of the limiting body 220 near the cover body 210 is located at the threaded hole and screwed to the guide body 500.

[0048] Please refer to the following: Figures 1 to 4 In one embodiment, the stop 300 and the lid 200 are integrally formed. Furthermore, the stop 300 and the lid 210 are integrally formed, improving the connection stability between the stop 300 and the lid 200, thereby improving the stopping stability of the stop 300 on the vehicle frame. Furthermore, the guide 500 and the lid 210 are integrally formed, improving the connection stability between the guide and the lid 210, thereby improving the sliding stability of the lid 200 on the box body 100.

[0049] Please refer to the following: Figures 1 to 4In one embodiment, at least one latch 600 is connected to the outer wall of the housing 100, and the latch 600 is used to fasten with the battery holder. Further, there are two latches, with the two latches located opposite each other on the two side walls of the housing. Further, there are three latches 600, with the three latches respectively disposed on three different outer walls of the housing 100. Further, there are four latches, with the four latches respectively disposed on four different outer walls of the housing. It should be noted that this application does not linearly specify the number of latches, but only aims to protect the housing by connecting it to the battery holder via the latches, thereby better ensuring the installation stability of the housing on the battery holder and facilitating the disassembly of the housing from the battery holder. That is, while ensuring the installation stability of the lock box on the battery holder, it also better ensures the ease of disassembly of the lock box, which is beneficial for maintenance and replacement, and improves the usability of the lock box.

[0050] This application also provides an energy storage device. Please refer to it as well. Figures 5 to 6 One embodiment of the energy storage device 10A includes a battery holder 20 and a lock box 10 of any of the above embodiments, with the box body 100 housed on the battery holder 20 and the box cover 200 exposed on the battery holder 20.

[0051] This application also provides an electric vehicle. Please refer to it as well. Figures 7 to 9 One embodiment of the electric vehicle 10B includes a primary lock 30 and a lock box 10 of any of the above embodiments. The primary lock 30 is for connection to the frame 40, and a portion of the primary lock 30 is for stopping on the battery holder 20. The stop member 300 is configured to move away from the frame 40 when the primary lock 30 is disengaged from the battery holder 20 until it stops on the frame 40.

[0052] Compared with the prior art, the present invention has at least the following advantages:

[0053] The lock box 10 of this utility model allows the box body 100 to be housed on the battery holder 20, and a stop 300 protruding from one side of the box cover 200 is used to stop on the frame 40. An elastic body 400 is configured to be retractably housed between the box cover 200 and the box body 100. The box cover 200 is slidably connected to the box body 100 in directions away from and towards the box body 100. Thus, when the elastic body 400 is housed between the box cover 200 and the box body 100, the compression of the elastic body 400 exerts an elastic thrust on the box cover 200 and the box body 100, forcing the box cover 200 and the box body 100 to slide apart. When a force is applied to press the box cover 200, causing it to slide towards the box body 100, the box cover 200 drives the stop 300 to move away from the frame 40 until it disengages. When the elastic body 400 is compressed away from the frame 40, it is easy to unlock by pressing. Then, when the force of pressing the cover 200 is removed, the elastic body 400, through its own elastic force after compression, pushes the cover 200 and the stop 300 away from the body 100 to restore the state of the cover 200 and the body 100 before pressing. The elastic body always prevents the stop 300 from being moved closer to the body 100 by the lock box 10, which better ensures the stability of the stop 300 of the lock box 10 on the vehicle and the structure is simple. In addition, the body 100 is housed on the battery holder 20. Even if the lock box 10 is not installed on the battery holder 20, the lock box 10 is not exposed to the frame 40, which better ensures the aesthetics and thus improves the user experience.

[0054] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
