Description

Technical Field

[0001] This utility model relates to the field of battery compartment technology, and specifically to a battery compartment structure. Background Technology

[0002] As electronic products become increasingly feature-rich and powerful, the number of batteries required also increases. Traditional battery compartments are machined and assembled on the product casing, demanding high-precision manufacturing and assembly processes, resulting in complex internal wiring and complicated repairs in case of problems. Chinese patent CN 105552265 A discloses a battery compartment structure where the negative and positive circuit boards are connected via probes. This allows batteries to be placed in the same orientation between the negative and positive circuit boards, eliminating the need for battery orientation correction, improving assembly accuracy, and facilitating battery replacement. Connecting the negative and positive circuit boards via probes simplifies the assembly process and avoids the lifespan defects caused by wires being susceptible to bending. However, this battery compartment structure still requires differentiation between positive and negative terminals. In military products, multiple batteries are connected in series and installed in the same orientation, making internal wiring even more complex. This necessitates a lighter battery compartment design and higher installation efficiency. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a battery compartment structure that is simple to wire and does not distinguish between positive and negative terminals.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a battery compartment structure, including an outer shell, a battery compartment assembly, a top cover assembly, and a locking assembly; the battery compartment assembly is fixedly connected to the outer shell, and the top cover assembly is rotatably connected to the outer shell; the battery compartment assembly includes a battery compartment body, a first circuit board, a conductive spring, and a spring pin, the spring pin being sealed and fixed on the battery compartment body and connected to the first circuit board via a wire; the top cover assembly includes a top cover body, a sealing body, a second circuit board, a spring, and a conductive copper pillar, the spring and the conductive copper pillar being welded to the second circuit board.

[0005] Furthermore, the locking assembly includes a locking shaft, a locking handle, and a spring pin. The locking shaft and the locking handle are rotatably connected by the spring pin. The locking shaft is inserted into one side of the upper cover to lock the upper cover and the outer shell.

[0006] The conductive copper pillar and the spring pin are adapted to connect the first circuit board and the second circuit board.

[0007] The battery compartment consists of three units, each with three corresponding spring pins and three corresponding conductive copper pillars, with each pillar positioned one-to-one.

[0008] The top cover assembly is connected to the outer shell via a threaded pin. The top cover assembly can rotate around the threaded pin at an angle of not less than 90 degrees for battery installation.

[0009] Compared with existing technologies, the advantages of this utility model are: The use of a spring pin in conjunction with a conductive copper pillar to connect the first and second circuit boards results in a compact and simple structure, easy wiring, and convenient maintenance. Furthermore, batteries can be installed in the same direction without needing to distinguish between positive and negative terminals. The battery compartment assembly is fixedly connected to the outer casing for easy installation; the battery cover is locked and sealed to the outer casing via a locking assembly, providing good protection and sealing. The battery compartment is made of a special plastic material, exhibiting high mechanical strength, impact resistance, light weight, resistance to high and low temperatures, good insulation, and facilitating modular design.

[0015] Reference Figure 1-5 As shown, a battery compartment structure includes an outer shell 1, a battery compartment assembly 2, a top cover assembly 3, and a locking assembly 4; Figure 1 As shown, the battery compartment assembly 2 is fixedly connected to the outer shell 1. Specifically, the battery compartment assembly is embedded in the outer shell and fixed with screws. The top cover assembly 3 is rotatably connected to the outer shell 1, and the connecting part is a threaded pin 5. Figure 3 As shown, the battery compartment assembly 2 includes a battery compartment body 22, a first circuit board 24, a conductive spring 23, and a spring pin 21. The spring pin 21 is sealed and fixed to the battery compartment body 22 and connected to the first circuit board 24 via a wire. Figure 4 As shown, the upper cover assembly includes an upper cover body 31, a sealing body 32, a second circuit board 33, a spring 34, and a conductive copper pillar 35. The spring and the conductive copper pillar are welded to the second circuit board 33. The sealing body is located at the bottom of the upper cover body to improve the sealing performance.

The locking shaft 41 and the locking handle 42 are rotatably connected by the spring pin 43. Figure 1 and Figure 2As shown, the locking shaft is inserted into one side of the upper cover to lock the upper cover and the outer shell together. A protruding structure on the outer shell engages with the locking shaft, making the locking action quick and simple.

[0017] like Figure 2-4 As shown, the conductive copper pillar 35 and the spring pin 21 are adapted to connect the first circuit board and the second circuit board. When the upper cover 31 and the outer shell 1 are locked, the conductive copper pillar and the spring pin make elastic contact, and the circuit is connected. At this time, the battery can be installed in the same direction without distinguishing between positive and negative terminals.

[0018] In this embodiment, there are three battery compartments 22, each with three corresponding spring pins and three corresponding conductive copper pillars, with their positions being one-to-one. This structure facilitates modular design, and the battery compartments are made of special plastic materials, which have high mechanical strength, impact resistance, light weight, resistance to high and low temperatures, and good insulation.

[0019] like Figure 2 As shown, the top cover assembly is connected to the outer casing via a threaded pin 5. The top cover assembly can rotate around the threaded pin at an angle of not less than 90 degrees, which is convenient for battery installation.
