Description

Technical Field

[0001] The utility model relates to a battery box for a night vision device, in particular to a battery box capable of being compatible with installing different types of batteries. Background Art

[0002] Nowadays, there are many electronic devices that use batteries. These devices are generally equipped with special battery boxes or battery compartments. The batteries are installed in the battery boxes or battery compartments to provide power for the electronic devices. The length and diameter of the existing battery boxes or battery compartments that hold the batteries are fixed and cannot be changed. By unscrewing the back cover, the specified type of battery is installed according to the positive and negative poles. Since the length and diameter of the battery holding part are fixed and cannot be changed, they are not compatible when faced with different types of batteries. When the environment does not allow the acquisition of the specified battery type, the electronic device cannot be used. This is especially true for battery boxes used in night vision goggles. Since night vision goggles are basically used outdoors for a long time at night, it is not convenient to obtain the specified type of battery. Once the battery in the night vision goggles is exhausted, the night vision goggles will face the dilemma of being unusable.

[0003] Therefore, how to design a battery box that is compatible with installing different types of batteries has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0004] The present invention aims to provide a battery pack compatible with different battery types, thereby resolving the problems identified in the aforementioned background art. To achieve this objective, the present invention provides the following technical solution: a battery pack compatible with different battery types, comprising a housing and a cover, the housing defining a cavity with an open end, and a battery conversion barrel disposed within the cavity, capable of varying the length of the portion of the cavity that accommodates the batteries.

[0005] Preferably, the battery conversion cylinder is in a cylindrical shape, one end of the battery conversion cylinder is an open end, and the other end is a closed end, and the battery conversion cylinder can change the direction of the open end in the cavity.

[0006] Preferably, an inner side of the cover body is provided with an internal thread, and both ends of the battery conversion cylinder are provided with external threads, and the battery conversion cylinder and the cover body can be fixed by the internal thread and the external thread.

[0007] Preferably, a protrusion is provided at the center of the closed end.

[0008] Preferably, the cover body is provided with a groove capable of accommodating the protrusion.

[0009] Preferably, an electrical connector is further included, and the electrical connector is fixed on a side of the housing close to the opening.

[0010] Preferably, when the opening end of the battery conversion cylinder faces opposite to the opening of the cavity, the protrusion of the battery conversion cylinder extends into the groove of the cover, and the cavity can accommodate AA batteries.

[0011] Preferably, when the opening end of the battery conversion cylinder faces the same direction as the opening of the cavity, the cavity can accommodate a CR123A battery, and the protrusion of the battery conversion cylinder is located in contact with the positive electrode of the CR123A battery.

[0012] Compared to existing technologies, this utility model utilizes a holistic design approach to accommodate two different battery types: AA batteries (size 5) and CR123A batteries (CR17335). Furthermore, the battery compartment maintains minimal volume change and provides reliable contact. AA batteries, as universal and widely available, are easily accessible, meeting the need for electronic devices to be able to replace batteries anytime, anywhere. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] This embodiment discloses a battery box that can be compatible with different types of batteries, such as Figure 1 As shown, the battery pack, which is compatible with different battery types, includes a housing 1 and a cover 2. The housing 1 defines a cavity 3 with an open end. It also includes a battery conversion barrel 4, which is disposed within the cavity 3 and can change the length of the portion of the cavity 3 that accommodates the batteries. The battery pack, which is compatible with different battery types, also includes an electrical connector 10, which is fixed to the side of the housing 1 near the opening.

[0020] like Figure 2 As shown, in this embodiment, the battery conversion barrel 4 is cylindrical, one end of the battery conversion barrel 4 is an open end 12, and the other end is a closed end 11. Both ends of the battery conversion barrel 4 are provided with external threads 13, and the center of the closed end 11 is provided with a protrusion 5.

[0021] In this embodiment, the orientation of the open end 12 of the battery conversion barrel 4 within the cavity 3 is adjustable. When the open end 12 of the battery conversion barrel 4 is oriented opposite to the opening of the cavity 3, that is, when the open end 12 of the battery conversion barrel 4 is oriented toward the battery, the positive end of the battery can be inserted into the battery conversion barrel 4. In this case, the cavity 3 can accommodate relatively long batteries, such as AA batteries 7. When the open end 12 of the battery conversion barrel 4 is oriented in the same direction as the opening of the cavity 3, that is, when the closed end 11 of the battery conversion barrel 4 is closer to the battery, the battery conversion barrel 4 occupies a portion of the cavity 3, shortening the portion of the cavity 3 that can accommodate batteries. In this case, the cavity 3 can only accommodate relatively short batteries, such as CR123A batteries 8. The cover 2 has internal threads 9 on its inside, and the battery conversion barrel 4 and the cover 2 can be secured together via the internal threads 9 and external threads 13. When the cover 2 is opened, the battery conversion cylinder 4 fixedly connected to the cover 2 is taken away together. At this time, the battery can be placed in the cavity 3, with the negative pole of the battery located at the closed bottom of the cavity 3 and the positive pole of the battery closer to the cover 2, and then the cover 2 is closed.

[0022] like Figure 1 and Figure 3 As shown, the cover 2 is further provided with a groove 6 capable of accommodating the protrusion 5 of the battery conversion barrel 4. When the battery box compatible with different battery types is loaded with an AA battery 7, the open end 12 of the battery conversion barrel 4 faces opposite to the opening of the cavity 3, and the protrusion 5 of the battery conversion barrel 4 extends into the groove 6 of the cover 2. The negative pole of the AA battery 7 is located at the closed bottom of the cavity 3, and the positive pole of the AA battery 7 is against the closed end 11 of the battery conversion barrel 4. The AA battery 7 almost fills the entire length of the cavity 3. Figure 3As shown. The recess 6 provided on the cover 2 accommodates the protrusion 5 of the battery converter 4, minimizing the length of the cavity 3 occupied by the battery converter 4 alone. This minimizes the length and volume of the battery case. Of course, in alternative embodiments, the cover 2 does not have the recess 6. In this case, the protrusion 5 of the battery converter 4 presses against the cover 2, increasing the length of the cavity 3. The battery converter 4 is made of a conductive material, and the positive terminal of the AA battery 7 is connected to the circuit through the battery converter 4 and the electrical connector 10.

[0023] The battery box of this embodiment is compatible with different battery types. Figure 1 When CR123A battery is inserted into the Figure 3 When the AA battery 7 needs to be replaced with a CR123A battery 8, it is only necessary to open the cover 2, manually rotate and remove the battery conversion barrel 4, turn the battery conversion barrel 4 180 degrees, and then fix the battery conversion barrel 4 to the cover 2. At this time, the battery conversion barrel 4 is fixedly connected to the internal thread 9 of the cover 2 through the external thread 13 of the open end 12, and then the CR123A battery 8 is installed. The negative electrode of the CR123A battery 8 is located at the closed bottom of the cavity 3, and the positive electrode of the CR123A battery 8 is closer to the battery conversion barrel 4. Finally, the cover 2 is closed. At this time, the protrusion 5 of the battery conversion barrel 4 is located in a position that contacts the positive electrode of the CR123A battery 8, that is, the positive electrode of the CR123A battery 8 just presses against the protrusion 5 of the battery conversion barrel 4. Figure 4 The positive terminal of the CR123A battery 8 is connected to the circuit through the battery conversion barrel 4 and the electrical connector 10.

[0024] The battery compartment of this embodiment, which is compatible with different battery types, can simultaneously accommodate two types of batteries, including AA batteries 7 and CR123A batteries 8. AA batteries 7 are widely available and easily accessible, meeting the requirement for electronic devices to be able to replace batteries anytime, anywhere. This is particularly true for night vision devices, as they can be replaced with a different type of battery in the field when the original battery is exhausted or low on power, ensuring continued operation.

[0025] Of course, in other embodiments, the battery box compatible with different battery types can be designed with cavities 3 of different sizes and lengths and battery conversion cylinders 4 of different sizes and lengths according to the batteries to be compatible, so as to be compatible with different types of batteries.

[0026] The improvements of the present invention do not involve other parts of the battery box and other circuit connections. The content can be clearly understood by ordinary technicians in this field through the description. Therefore, the present invention omits the schematic diagrams of other parts of the battery box and other circuit connections.

[0027] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. "Above" and "below" are inclusive.
