Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] like Figures 1 to 5 As shown, this embodiment provides a waterproof snap-on battery compartment cover, including a housing 1. The housing 1 has a snap-on part for snapping into the battery compartment body. An electrode plate 7 is installed on the snap-on part. A waterproof seal is provided at the snap-on part. When the battery compartment cover is closed with the battery compartment body, the waterproof seal seals the connection between the housing 1 and the compartment body, achieving the purpose of sealing and waterproofing. A movable snap 2 is provided inside the housing 1 away from the snap-on part. One end of the movable snap 2 penetrates the surface of the housing 1 and is used to snap and fix with a corresponding slot on an external device. At the same time, the housing 1 is also provided with a power component for extending and retracting the movable snap 2. The power component acts on the movable snap 2 to extend and retract, realizing the opening and closing function of the battery compartment cover snapping with the external device. In this embodiment, the active buckle 2 is designed to lock with an external device outside the battery compartment body, avoiding the problem of poor waterproofing of the battery compartment body caused by the direct snapping of the existing buckle to the battery compartment body. At the same time, the design of the waterproof seal achieves the sealing and waterproofing function of the connection between the battery compartment cover and the battery compartment body. It requires fewer parts, is easy to install, and has high assembly and production efficiency.

[0030] In an optional embodiment, the housing 1 includes a front cover 10, a middle cover 11, and a rear cover 12. The movable buckle 2 and the power assembly are placed between the front cover 10 and the middle cover 11. The fastening part is located on the rear cover 12. The electrode plate 7 and the waterproof seal are connected to the rear cover 12. Through this partitioned design of the housing 1, the spacing of the middle cover 11 can further improve the waterproof effect of the electrode plate 7 and the electrode inside the battery compartment.

[0031] As one specific implementation method, such as Figure 3 and Figure 5As shown, the power assembly includes a snap-fit ​​spring 9 and an ear block 3. One end of the snap-fit ​​spring 9 is fixedly connected to the housing 1, and the other end is connected to the movable snap-fit ​​2. In the initial state, the movable snap-fit ​​2 will naturally extend out of the housing 1 under the elastic force of the snap-fit ​​spring 9. The ear block 3 is rotatably connected to the housing 1. Specifically, the housing 1 is provided with a rotating shaft 14, and the bottom of the ear block 3 is provided with a shaft hole that cooperates with the rotating shaft 14. The upper part of the ear block 3 passes through the surface of the housing 1, and the ear block 3 can rotate around the rotating shaft 14 under external force. Of course, the housing 1 has an active space for the ear block 3 to rotate, and the ear block 3 has a pressing part 13 for pressing the movable snap-fit ​​2. When the battery compartment cover is closed, the movable latch 2 contacts the latch position of the external device. The movable latch 2 retracts and, after reaching the slot position of the external device, it pops out under the elastic force of the latch spring 9 and locks in the slot of the external device, realizing the "closing" function of the movable latch. When it is necessary to open the battery compartment cover, a force can be applied to the lug 3, causing the lug 3 to rotate around the pivot 14. The pressing part 13 of the lug 3 presses the movable latch 2, and the movable latch 2 retracts under this action and exits the slot of the external device, thereby unlocking the external device and realizing the "opening" function of the movable latch.

[0032] Preferably, the design can include two of each of the latching springs 9 and ear blocks 3. The two latching springs 9 are respectively connected to the left and right ends of the movable latch 2, and the pressing parts 13 of the two ear blocks 3 press against the surfaces of the movable latch 2 facing away from the latching springs 9. When the battery compartment cover needs to be opened, the left and right ear blocks 3 can be pressed towards the middle with two fingers. This opening method of the left and right ear blocks 3 interlocking also ensures that the movable latch is not easy to slip and loosen under accidental touch, drop or impact. For applications with high fastening requirements, the risk of jamming and failure is low. At the same time, the unlocking method of the left and right ear blocks 3 interlocking is in line with human usage habits, has good force distribution, and provides a good opening and closing feel.

[0033] In this embodiment, the outline and travel length of the left and right ear blocks 3 can be designed as needed. By controlling the coordination stop and movement path of the left and right ear blocks 3 and the ear blocks 3 opened on the housing 1, the travel and length of the movable buckle 2 can be customized as needed within a certain range.

[0034] To further optimize the technical solution, a guide groove 15 is provided inside the housing 1 for guiding the extension and retraction of the movable buckle 2, and the buckle spring 9 is placed inside the guide groove 15, thereby effectively ensuring the stability of the extension and retraction movement of the movable buckle 2.

[0035] In one specific embodiment, the waterproof seal includes a sealing gasket 5 and a sealing pressure plate 4. The sealing gasket 5 has a sealing part and a connecting part. The connecting part is located at both ends of the sealing part. The sealing gasket is fixed to the housing 1 through the connecting part, and the sealing pressure plate 4 is pressed onto the connecting part.

[0036] In an optimized configuration, the snap-fit ​​portion of the housing 1 has an installation groove recessed into the housing 1, the electrode plate 7 is fixedly installed in the installation groove, and the sealing gasket 5 of the waterproof seal is an annular structure arranged around the installation groove, further improving the sealing and waterproofing effect on the electrode plate 7.

[0037] Furthermore, an electrode buffer spring 8 is installed on the electrode plate 7. When the battery compartment cover is closed, the electrode buffer spring 8 buffers the connection between the electrode plate 7 and the electrodes inside the battery compartment, so as to protect the electrode plate 7 and the electrodes.

[0038] In a preferred embodiment, the housing 1 has a flipping assembly on the side opposite to the movable buckle 2 for rotatably connecting with the battery compartment body. The flipping assembly connects the battery compartment cover to the compartment body, preventing the battery compartment cover from falling off after opening. In some embodiments, the flipping assembly includes a flipping spring 6. The housing 1 has a spring slot for installing the flipping spring 6. Correspondingly, a spring shaft is provided on the battery compartment body, and the flipping spring 6 is sleeved on the spring shaft. When it is necessary to open the battery compartment cover, pressing the ear block 3 causes the movable buckle 2 to retract into the housing. Under the action of the flipping spring 6, the battery compartment cover will naturally flip open, thus opening the battery compartment cover. Moreover, when the battery compartment cover is in the closed state, the flipping spring 6 has an elastic force on the battery compartment cover, which can further improve the locking effect of the movable buckle 2 and the tight fit between the waterproof seal and the battery compartment body.

[0039] The assembly process of the battery compartment cover in the above embodiment is as follows: First, place the two left and right ear blocks 3 into the holes of the front cover 10 of the housing 1, fasten the middle cover 11 of the housing 1 to the front cover 10, and lock the middle cover 11 and the front cover 10 with screws; then, place the movable buckle 2 into the guide groove 15 on the front cover 10, and install the buckle spring 9 into the guide groove 15. At this time, the movable buckle 2 can naturally extend out of the empty space on the middle cover 11 to reach the working position under the pre-tightening force of the buckle spring 9; then, install the rear cover 12 onto the middle cover 11 according to the mating positioning, install the sealing gasket 5 onto the rear cover 12, align the electrode plate 7 protrusion with the mounting groove on the rear cover 12 and install it, and tighten the screws; finally, tighten the two sealing pressure plates 4 onto the front cover 10 with screws according to the positioning position, and install the flip spring 6 into the spring groove below the middle cover 11, thus completing the assembly of the entire battery compartment cover.

[0040] The waterproof snap-on battery compartment cover provided in this embodiment achieves snap-locking with external devices through a movable snap-on mechanism. At the same time, the design of the waterproof sealing component achieves the sealing and waterproof function between the battery compartment cover and the external device. It requires fewer parts, is easy to install, and has high assembly and production efficiency.

[0041] In addition, this embodiment also provides a battery compartment, including a compartment body and the aforementioned waterproof snap-on battery compartment cover. The snap-on portion of the waterproof snap-on battery compartment cover is snapped into the compartment body, and the electrode plate is connected to the electrode inside the compartment body. The waterproof seal seals the connection between the housing of the waterproof snap-on battery compartment cover and the compartment body, and the movable snap is located outside the compartment body.

[0042] The above examples are merely illustrative of the present invention and do not constitute a limitation on the scope of protection of the present invention. All designs that are the same as or similar to the present invention are within the scope of protection of the present invention.
