[0034] See also Figures 1 to 3 The device with a battery compartment of the embodiment of the present application includes a battery compartment, and the battery compartment includes a compartment body 2, a compartment cover assembly 1, a circuit board 7, a first elastic member 6, and a second elastic member 4. The device with a battery compartment may be, for example, an electronic or electrical device such as an infrared thermal imager.

[0035] The bin body 2 and the bin cover assembly 1 are respectively made of conductive materials; the bin cover assembly 1 is used to cover the opening end 21 of the bin body 2 and is in electrical communication with the bin body 2 .

[0036] In this embodiment, the bin body 2 and the bin cover assembly 1 are respectively made of aluminum alloy materials. Aluminum alloy materials have excellent mechanical processing properties, and have low density, light weight, high specific strength, and good impact performance. The bin body 2 of this embodiment is a cylindrical structure with an open end 21. The other end of the bin body 2 opposite to the open end 21 is provided with a first mounting portion 22, and the first mounting portion 22 is provided with a mounting hole 221. The first mounting portion 22 is arranged along the cross-sectional direction of the bin body 2, and the mounting hole 221 is opened in the middle of the first mounting portion 22, and the mounting hole 221 is a through hole. An extension portion 23 is provided on the outer side of the first mounting portion 22, and the extension portion 23 is a cylindrical structure formed by extending from the end of the bin body 2 to a direction away from the first mounting portion 22.

[0037] The circuit board 7 of this embodiment is a PCB board, and the circuit board 7 is provided with a positive terminal (not shown) at the center of one side surface close to the opening end 21, and a negative terminal (not shown) at the edge of the other side surface. The circuit board 7 is installed outside the first mounting portion 22, located in the cylindrical structure formed by the extension portion 23, and the positive terminal side is arranged toward the first mounting portion 22.

[0038] In order to facilitate the conduction between the negative terminal of the circuit board 7 and the chamber body 2 and facilitate the installation and fixation between the circuit board 7 and the chamber body 2, a pressure ring 8 can also be provided. The pressure ring 8 can be made of conductive metal, for example, it can be made of the same aluminum alloy material as the chamber body 2. The circuit board 7 is installed between the first installation part 22 and the pressure ring 8. In this embodiment, the outer circumference of the pressure ring 8 is provided with an external thread, and the inner surface of the extension part 23 is provided with an internal thread. The external thread of the pressure ring 8 and the internal thread of the extension part 23 form a threaded connection, which can make the circuit board 7 and the chamber body 2 form a fixed structure. At the same time, the pressure ring 8 is connected to the negative terminal. Through the threaded connection with the chamber body 2, the negative terminal of the circuit board 7 and the chamber body 2 are connected, eliminating the trouble of additionally setting a connecting wire in the ordinary battery chamber, and at the same time, its connection structure is more stable and reliable. The pressure ring 8 and the chamber body 2 form a detachable connection through a thread, which can facilitate the replacement and disassembly of the circuit board 7 and its connection structure.

[0039] like Figure 2 and Figure 3 As shown, the bin cover assembly 1 includes a bin cover body 11 and an insert 12. The insert 12 is threadedly connected to the bin cover body 11 and the bin body 2, respectively, and the hardness of the insert 12 is greater than the hardness of the bin cover body 11. In this embodiment, the insert 12 is made of copper alloy material, and hard conductive metals of other materials can also be selected according to actual needs. The hard material can reduce the chip shedding phenomenon when the bin cover assembly 1 is screwed in or out, and improve the cleanliness. The additional configuration of the insert 12 structure can maintain the overall material consistency of the bin cover assembly 1 and the bin body 2, which can reduce the overall mass of the battery bin and reduce the manufacturing cost (the price of copper material is higher). At the same time, when the insert 12 has problems such as thread slippage, the detachable connection structure can facilitate the replacement of the insert 12.

[0040] The first elastic member 6 is disposed in the housing 2, one end of which is connected to the positive terminal, for example, a conductive structure can be formed with the positive terminal by soldering; the other end is used to abut against the positive electrode of the battery 9. In this embodiment, the first elastic member 6 is a tower spring, the large end of the tower spring is electrically connected to the positive terminal, and the small end of the tower spring is used to abut against the battery 9.

[0041] The second elastic member 4 is arranged in the bin cover assembly 1, one end of which is connected to the bin cover assembly 1, and the other end is used to abut against the negative electrode of the battery 9; the negative terminal is connected to the bin body 2. In order to facilitate the disassembly and installation of the second elastic member 4 (the material needs to be nickel-plated on the surface to form a welding structure), a fixing block 3 can also be provided. The fixing block 3 is made of a conductive metal material, such as an aluminum alloy material that is the same as the bin body 2, and then the surface is nickel-plated. The fixing block 3 is arranged in the bin cover assembly 1, and its surface close to the bin body 2 is welded and fixed to the second elastic member 4. In this embodiment, the second elastic member 4 is also a tower spring, the large end of the tower spring is electrically connected to the fixing block 3, and the small end of the tower spring is used to abut against the battery 9. For easy disassembly and assembly, the fixing block 3 and the bin cover assembly 1 can be set to be detachably connected, for example, threaded connection. In this embodiment, the surface of the bin cover body 11 close to the bin body 2 is provided with a second mounting portion 111, and the fixing block 3 and the second mounting portion 111 are threadedly connected. For example, the second mounting portion 111 is an inwardly recessed groove structure, an internal thread is provided on the second mounting portion 111, and an external thread is provided on the outer periphery of the fixing block 3. After the external thread of the fixing block 3 and the internal thread of the second mounting portion 111 form a threaded connection, the second elastic member 4 and the compartment cover assembly 1 are connected.

[0042] In practical applications, the stiffness coefficient of the first elastic member 6 can be set to be greater than the stiffness coefficient of the second elastic member 4, so that the second elastic member 4 is easier to be compressed and deformed, and has a larger deformation when compressed, which is beneficial to reducing the length of the entire battery compartment.

[0043] In order to avoid excessive compression of the first elastic member 6 and the second elastic member 4, and at the same time, to prevent the battery 9 from moving in the battery compartment due to impact, etc., a first stopper 5 and a second stopper 112 may be provided. For example, the first stopper 5 may be provided on the surface of the first mounting portion 22 away from the circuit board 7, and the first stopper 5 may be made of a soft material, such as silica gel. The soft material can reduce the impact force of the battery 9, thereby protecting the battery 9. Figure 2 and Figure 3As shown, the first stopper 5 can be set as a cylindrical structure, which is arranged around the periphery of the first elastic member 6. At the same time, the first elastic member 6 can be configured so that when it is compressed to the minimum length, the end of the first elastic member 6 is located inside the first stopper 5 (that is, when one end of the battery 9 abuts against the first stopper 5, the first elastic member 6 is not in a state of being compressed to the minimum length, and the first elastic member 6 still has a compressible amount). Figure 3 and Figure 4 As shown, the second stopper 112 can be arranged in the compartment cover assembly 1, for example, on the surface of the compartment cover body 11 close to the compartment body 2, or the second stopper 112 is directly integrally formed with the compartment cover body 11. The second stopper 112 can also be arranged as a cylindrical structure, which is arranged around the periphery of the second elastic member 4. Similarly, the second elastic member 4 can be configured so that when it is compressed to the minimum length, the end of the second elastic member 4 is located in the second stopper 112 (that is, when one end of the battery 9 abuts against the second stopper 112, the second elastic member 4 is not in a state of being compressed to the minimum length, and the second elastic member 4 still has a compressible amount). The first stopper 5 is used to contact the end of the positive end of the battery 9, and the second stopper 112 is used to contact the end of the negative end of the battery 9.

[0044] In order to adapt to batteries 9 of different lengths and ensure that the batteries 9 can form a stable electrical connection with the battery compartment, the first elastic member 6 can be configured so that when the second elastic member 4 is compressed to the limit length, the first elastic member 6 can still abut against the positive electrode of the battery 9. The second elastic member 4 can be configured so that when the first elastic member 6 is compressed to the limit length, the second elastic member 4 can still abut against the negative electrode of the battery 9.

[0045] For example, if the battery compartment is not provided with the first stopper 5 and the second stopper 112, when the two elastic members are compressed to the minimum length, the distance between the tops of the two elastic members is the maximum length of the battery 9 that the battery compartment can accommodate. When the first elastic member 6 is in a free state and the second elastic member 4 is compressed to the minimum length, the distance between the tops of the two elastic members is L1; when the second elastic member 4 is in a free state and the first elastic member 6 is compressed to the minimum length, the distance between the tops of the two elastic members is L2; ​​at this time, the smaller of L1 and L2 is the minimum length of the battery 9 that the battery compartment can accommodate.

[0046] If the battery compartment is provided with a first stopper 5 and a second stopper 112, the distance between the tops of the two stoppers (the first stopper 5 and the second stopper 112) is the maximum length of the battery 9 that can be accommodated in the battery compartment (e.g. Figure 5, which is a schematic diagram of the state when accommodating a battery 9 of maximum length, at this time, both ends of the battery 9 are in contact with two stoppers respectively). When the first elastic member 6 is in a free state, the distance between the first elastic member 6 and the top of the second stopper 112 is L3; when the second elastic member 4 is in a free state, the distance between the second elastic member 4 and the top of the first stopper 5 is L4; at this time, the smaller one of L3 and L4 is the minimum length of the battery 9 that can be accommodated in this battery compartment.

[0047] like Figure 6 The figure is a schematic diagram of the state when the battery compartment accommodates a shorter length battery 9. It can be seen in the figure that when the battery 9 is not subjected to impact force, both ends of the battery 9 are not in contact with the stopper. When the battery 9 is subjected to impact force, one end contacts the stopper, and the elastic member at the other end can still maintain stable contact with the other end of the battery 9 after stretching, so that the battery compartment can meet the assembly requirements of batteries 9 of different lengths and ensure the stability of the connection.

[0048] That is, when the first stop portion 5 and the second stop portion 112 are not set, the elastic member is compressed to the minimum length when it is compressed to the limit length; when the first stop portion 5 and the second stop portion 112 are set, the elastic member is compressed to the limit length when it is compressed to be flush with the top of the corresponding stop portion; when only the first stop portion 5 or only the second stop portion 112 is set, the same applies and will not be repeated.

[0049] The battery compartment provided in the embodiment of the present application realizes the connection between the negative electrode of the battery and the negative electrode of the circuit board by arranging positive and negative terminals on the circuit board, and connecting the compartment body and the negative electrode terminal through the connection structure of the compartment body of the battery compartment, and connecting the negative electrode terminal and the compartment cover assembly through the second elastic member, and the compartment cover assembly is connected to the compartment body. This connection structure does not require welding and wiring, and the structure is very simple, while the conduction performance is stable and reliable.

[0050] The battery compartment of the embodiment of the present application, through its overall structure and the provision of two elastic parts, can meet the assembly requirements of batteries of different lengths and adapt to the needs of different regional markets, so that the device with the battery compartment maintains overall structural consistency. For product sales and the requirements of different regional markets, it is only necessary to equip batteries of different lengths according to actual needs, which greatly increases the convenience of the product production and sales processes, facilitates production management, and is conducive to mass production.

[0051] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0052] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
