Description

Technical Field

[0001] This application relates to the field of building block technology, specifically to a building block battery box. Background Technology

[0002] Building block sets are a type of toy that allows for creative assembly through standardized modular combinations. They consist of interlocking plastic or wooden particles that are stably joined together through a textured structure. From simple geometric shapes to complex mechanical structures, users can freely combine them to create diverse scenes such as buildings and vehicles.

[0003] To further enhance the playability and aesthetics of building block sets, decorative lights are increasingly being added, combining decoration and practicality. These lights are typically powered by a battery compartment. Some national safety regulations mandate that the battery compartment must have at least two independent steps to open, preventing accidental opening by children and avoiding safety risks such as children swallowing batteries due to design flaws.

[0004] In existing technologies, the battery is typically secured with screws on a cover. However, this requires removing the screws to open the cover, which is cumbersome because it necessitates unscrewing the screws before removing the cover. Furthermore, existing battery boxes lack any interfacing with building blocks, making them unsuitable for direct mounting and resulting in poor compatibility. Utility Model Content

[0005] The purpose of this application is to provide a convenient battery box for building blocks, which is simple to operate, eliminates the traditional screw connection structure, and greatly improves assembly efficiency. When it is necessary to install or replace the battery, the user needs to move the lever to disengage the limiting member from the connector, and then slide the cover away from the box. This meets the requirement that the battery cannot be removed directly without tools and that at least two independent actions are required to open the battery box, thereby improving the safety of children using the battery box of this application.

[0006] To achieve the above objectives, this application provides the following technical solution: A building block battery box includes a box body with an opening and a cover. The cover cooperates with the box body and is used to cover the opening of the box body. The cover is provided with a connector that is inserted into the box body. The box body is provided with a limiting rod and an elastic element. The limiting rod can move relative to the box body in a direction that is closer to or farther away from the connector. One end of the limiting rod is connected to the elastic element, and the other end cooperates with the connector under the elastic action of the elastic element to prevent the cover from detaching from the box body.

[0007] Further configuration: The connector includes a connecting rod protruding from the surface of the cover and extending outward, and the connecting rod is provided with a connecting hole for the insertion and engagement of a limiting rod.

[0008] Further configuration: The end of the limiting rod used for insertion into the connecting hole is provided with a wedge-shaped surface, and the end of the connecting rod abuts against the wedge-shaped surface to push the connecting rod to move in the direction of the elastic element.

[0009] Further configuration: The limiting rod is connected to a lever for driving the limiting rod to move closer to the elastic element to disengage from the connecting hole. A limiting groove is provided on the box body, and the lever slides in the limiting groove.

[0010] Further configuration: The elastic element includes a compression spring, one end of which is fixed to the housing and the other end is connected to the connecting rod.

[0011] Further configuration: The end of the connecting rod used to connect with the compression spring is provided with a fixing rod, and the compression spring is sleeved on the fixing rod.

[0012] Further configuration: The cover and the box body are slidably fitted. The cover has guide rails on its opposite sides, and the guide rails extend along the length of the side of the cover. The box body is further configured such that: the connector is located on one side between the two guide rails of the cover, and the other side opposite to that side has a buckle; the box body has a connecting hole for the connector to be inserted on one side between the two guide rail ribs at its opening, and a buckle hole for engaging with the buckle of the cover on the other side opposite to that side.

[0013] Further configuration: The box body has a positioning block at the end of the side where the buckle is located, corresponding to the guide rail rib. The positioning block protrudes from the box body to guide the guide rail of the cover to align with the guide rail rib of the box body.

[0014] Further configuration: The outer side of the cover is provided with building block protrusions and / or building block recesses, and the outer side of the box body is provided with building block protrusions and / or building block recesses.

[0015] Compared with existing technologies, the solution in this application has the following advantages: 1. In the battery box of this application, the cover and the box body are locked by sliding the cover and inserting the connector into the connecting hole of the box body. The operation is simple, eliminating the traditional screw connection structure and greatly improving assembly efficiency. When it is necessary to install or replace the battery, the user needs to turn the lever to disengage the limiting member from the connector, and then slide the cover away from the box body. This meets the requirement that the battery should be difficult to remove without tools, and that at least two independent actions are required to open the battery box, thus improving the safety of children using the battery box of this application.

[0016] 2. In the building block battery box involved in this application, in addition to the structural cooperation of the connector, limiting member and elastic member to lock the cover and the box body, a buckle of the cover and a buckle hole of the box body are added to cooperate, which can further improve the stability of the connection between the cover and the box body.

[0017] 3. In the building block battery box involved in this application, the cover and the box body slide together through the guide rail and guide rail rib to avoid stress concentration or other movement interference caused by installation deviation, and to ensure that the connecting parts of the cover are inserted into the box body and cooperate with the limiting parts.

[0025] It should be noted that the concepts of "first" and "second" mentioned in this utility model are only used to distinguish between devices, modules or units, and are not used to limit these devices, modules or units to necessarily be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0026] Please combine Figures 1 to 7This application provides a modular battery box, comprising a box body 2 and a cover 1. The box body 2 has an opening for easy installation of batteries. The cover 1 cooperates with the box body 2 and covers the opening of the box body 2 to encapsulate the batteries inside the box body 2. The cover 1 has a connector 3 that inserts into the box body 2. The box body 2 has a limiting member 4 and an elastic member 5 that cooperate with the connector 3 to prevent the cover 1 from detaching from the box body 2. This solves the problem of cumbersome operation in the prior art where screws are used to fix the cover 1 and the box body 2.

[0027] Specifically, the connector 3 includes a connecting rod 31 protruding from the surface of the cover 1 and extending outward. Optionally, the connecting rod 31 is located on the side of the cover 1. The connecting rod 31 has a connecting hole 32. The box body 2 has a connecting hole position 211 for the connecting rod 31 to be inserted into the box body 2. The limiting part is located inside the box body 2. The limiting member 4 includes a limiting rod 41. One end of the limiting rod 41 is connected to the elastic member 5. The other end can be inserted into the connecting hole 32 of the connecting rod 31 under the elastic action of the elastic member 5 to form a mechanical interlock, thereby locking the cover 1 and the box body 2. This prevents the cover 1 from separating from the box body 2 under slight external force, thus meeting the usage requirements of the battery box.

[0028] In this embodiment, the connecting rod 31 is arranged parallel to the cover 1 and extends outward from the side of the panel to form a cantilever structure. The cover 1 and the box body 2 are connected by a sliding fit. In other embodiments, the connecting rod 31 is arranged perpendicular to the cover 1, and the cover 1 can be directly closed onto the opening of the box body 2. The connecting rod 31 is vertically inserted into the box body 2 to achieve connection. The specific arrangement needs to be designed according to the structure of the box body 2.

[0029] Furthermore, the movement path of the limiting rod 41 in the box 2 is perpendicular to the insertion path of the connecting rod 31 into the box 2. Under the action of the elastic element 5, the end of the limiting rod 41 that mates with the connecting rod 31 enters the aforementioned connecting hole 211. Simultaneously, a wedge-shaped surface is provided at the end of the limiting rod 41 that mates with the connecting rod 31. When the connecting rod 31 is inserted into the box 2, its end abuts against the wedge-shaped surface. If the pushing positioning rod moves towards the elastic element 5, the elastic element 5 is compressed. After the connecting rod 31 is inserted into place, the limiting rod 41, under the elastic recovery action of the elastic element 5, is inserted into the connecting hole 32 on the connecting rod 31. Due to the elastic action of the elastic element 5, the limiting rod 41 cannot leave the connecting hole 32 without external force or with only slight external force. That is, through the synergistic action of the limiting wedge-shaped surface and the elastic element 5, low-resistance insertion and high-reliability locking between the limiting rod 41 and the connecting rod 31 are achieved, thereby completing the locking of the cover 1 and the box 2.

[0030] In this embodiment, the elastic element 5 is a compression spring. One end of the compression spring is fixed to the housing 2, and the other end is connected to the limiting rod 41. To improve the connection stability between the compression spring and the limiting rod 41, a fixing rod 42 is provided at the end of the limiting rod 41. The diameter of the fixing rod 42 matches the inner diameter of the spring, and the height of the rod is greater than 1.2 times the spring compression stroke, thereby preventing radial displacement during the spring compression process. In addition, the housing 2 is also provided with a spring groove 212 for mounting and fixing the compression spring. The spring groove 212 can ensure the accuracy of the installation position and avoid stress concentration or motion interference caused by installation deviation.

[0031] Furthermore, the limiting rod 41 is connected to a lever 43 for driving the limiting rod to move closer to the elastic member 5. As the limiting rod 41 moves away from the elastic member 5, it moves away from the connecting rod 31, releasing the limiting rod 41 from its restriction on the connecting rod 31. This allows the connecting rod 31 to be pulled out of the box 2, thereby releasing the lock between the cover 1 and the box 2. Simultaneously, a limiting groove 213 is provided on the box 2, extending in the same direction as the moving path of the limiting rod 41. The lever 43 is positioned within the limiting groove 213 and moves along its direction, effectively preventing the limiting rod 41 from shifting. The limiting groove 213 penetrates the side wall of the box 2, and the top of the lever 43 extends to the surface of the box 2 for user operation.

[0032] Furthermore, the surface of the lever 43 is provided with anti-slip protrusions 44, which can enhance the friction between the user and the surface of the lever 43, so as to better move the lever 43 to control the movement of the limit rod 41.

[0033] In this embodiment, the cover 1 and the box body 2 are slidably fitted. Specifically, the cover 1 has guide rails 11 on its opposite sides, and the box body 2 has guide rail ribs 214 on its corresponding sides at its opening, which cooperate with the guide rails 11. This ensures that the cover 1 can only slide in a preset direction, effectively preventing misalignment during assembly. The connector 3 is installed on one side of the cover 1 between the two guide rails 11, and the opposite side has a snap fastener. Similarly, the box body 2 has a connecting hole 211 for the connector 3 to be inserted on one side between the two guide rail ribs 214 at its opening, and a snap fastener hole for the snap fastener of the cover 1 on the other side of the two guide rail ribs 214. After the cover 1 and the box body 2 are assembled, the connection stability between the cover 1 and the box body 2 can be further improved by the cooperation of the snap fastener and the snap fastener hole.

[0034] Specifically, the buckle in this embodiment includes a first buckle 12 located in the middle of the side of the cover 1, and a first buckle hole 215 corresponding to the middle of the side of the box body 2 that cooperates with the first buckle 12.

[0035] Furthermore, the latch also includes a third latch 14 disposed on the cover 1 along the extension direction of the guide rail 11. The third latch 14 is located at both ends of the side of the cover 1. Correspondingly, the two ends of the side of the box body 2 are provided with third latch holes 217 that cooperate with the third latch 14. When the cover 1 is driven to slide relative to the box body 2, that is, when the cover 1 is driven to move relative to the guide rail 11 and the guide rail rib 214, until the connecting rod 31 is inserted into the connecting hole 211, the positioning connection between the third latch 14 and the third latch hole 217 can further improve the stability of the corresponding connection between the guide rail 11 and the guide rail rib 214.

[0036] Preferably, the box body 2 has a positioning block 218 protruding from the end of the guide rail rib 214. One positioning block 218 is provided at each end of the side of the box body 2 where the snap-fit ​​hole is located. The positioning block 218 engages with the side wall of the cover 1 to limit the movement, guiding the user to align the guide rail 11 of the cover 1 with the guide rail rib 214 of the box body 2. Subsequently, the cover 1 can be quickly moved relative to the box body 2 along the guide rail 11, reducing the adjustment process during installation. In this embodiment, the third snap-fit ​​hole 217 is formed on the positioning block 218. A positioning groove 15 is formed between the bottom surface of the cover 1 and the third snap-fit ​​14. The positioning groove 15 can accommodate the positioning block 218. The positioning block 218 is embedded in the positioning groove 15 so that the third snap-fit ​​14 engages with the third snap-fit ​​hole 217, achieving further connection between the cover 1 and the box body 2.

[0037] The housing 2 of this application contains several independent charging compartments. Each independent battery compartment supports single-compartment maintenance or battery replacement. A partition 6 is provided between two adjacent independent charging compartments. The partition 6 can block heat dissipation between adjacent batteries and reduce the risk of chain reaction. The bottom of the partition 6 has a cable routing groove 61 for fixing the wires, reducing the safety risks caused by wire tangling and improving the safety of use.

[0038] In addition, the inner side of the cover 1 is provided with a limiting rib 13, which forms a groove structure that matches the outer contour of the battery, so as to cooperate with the separator 6 to form a limiting space for battery installation and fixation, thereby improving the stability of battery assembly.

[0039] In this embodiment, the box body 2 can be further divided into a base 22 and a middle shell 21. The base 22 is connected to one side of the middle shell 21, and the opening is located on the other side of the middle shell 21 opposite to the base 22. The cover 1 is connected to the side of the middle shell 21 with the opening. That is, the building block battery box of this application is assembled from the cover 1, the middle shell 21, and the base 22. The outer contour shape of the base 22 is the same as the outer contour shape of the middle shell 21, the outer contour shape of the cover 1 is the same as the shape of the opening, the partition 6 is fixed inside the middle shell 21, the base 22 is provided with a second buckle 221 along its circumference, and the circumferential side of the middle shell 21 is provided with a second buckle hole 216 for the second buckle 221 to be inserted for engagement, which can realize the quick positioning and assembly of the base 22 and the middle shell 21. In other embodiments, the base 22 and the middle shell 21 can also be configured as an integrally formed box body 2 structure.

[0040] In addition, in this embodiment, the limiting member 4 and the elastic member 5 are both installed on the middle shell 21. Since this application splits the box body 2 into the middle shell 21 and the base 22, the middle shell 21 serves as an intermediate carrier, which facilitates the pre-installation of the limiting member 4 and the elastic member 5. Then, the base 22 is used to encapsulate and form a closed structure, which avoids external impacts from directly acting on the limiting member 4 and the elastic member 5 and affecting the assembly stability of the cover 1 and the box body 2. It also facilitates the installation of the limiting member 4 and the elastic member 5, which is convenient for subsequent maintenance and replacement, and helps to extend the service life of the building block battery box of this application.

[0041] The faceplate 1 and base 22 of this application are provided with building block interfaces 7 such as building block protrusions and / or building block recesses on the surface away from the middle shell 21. The building block protrusions and building block recesses are all of standardized size, which can support assembly with third-party building block components, so that the building block battery box of this application can be installed on different building block structures to meet the usage needs in different scenarios.

[0042] In summary, the battery box of this application achieves locking between the cover 1 and the box body 2 through the coordinated action of the connector 3, the limiting member 4, and the elastic member 5. Specifically, locking the cover 1 and the box body 2 is achieved by sliding the cover 1 and inserting the connector 3 into the connecting hole 211 of the box body 2. The operation is simple, eliminating the traditional screw connection structure and greatly improving assembly efficiency. When it is necessary to install or replace the battery, the user needs to move the lever 43 to disengage the limiting member 4 from the connector 3, and then slide the cover 1 away from the box body 2. This meets the requirement that the battery should be difficult to remove without tools, and that at least two independent actions are required to open the battery box, thus improving the safety of children using the battery box of this application.

[0043] Based on the structural cooperation of the aforementioned connector 3, limiting member 4, and elastic member 5, this application further adds a first buckle 12 of the cover 1 and a first buckle hole 215 of the box body 2 for cooperation, which can further improve the stability of the connection between the cover 1 and the box body 2. At the same time, the cover 1 and the box body 2 also slide through the guide rail 11 and the guide rail 11 rib cooperation to avoid stress concentration or other movement interference caused by installation deviation, and ensure that the connector 3 of the cover 1 is inserted into the box body 2 and cooperates with the limiting member 4.

[0044] The building block battery box of this application has a wide range of applications because it has a building block interface structure 7 with building block protrusions or concave points on its surface. It can be installed in any position of the building block set.

[0045] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
