Technical Field
[0001] This utility model relates to the field of timer switch technology, specifically to a battery mounting structure for a timer switch. Background Technology
[0002] In various timer switch products, the battery is the core power supply component, and the rationality of its installation structure directly affects the product's ease of use and maintenance efficiency. Currently, most common timer switch battery installation structures on the market adopt either a cover-plate snap-fit design or a screw-fixed design: the cover-plate snap-fit structure usually integrates the battery compartment inside the bottom shell, and the cover is fixed by a snap or rotation method. When replacing the battery, the cover must be removed first. During the operation, the cover is prone to loosening due to wear of the snaps, and the internal battery is often restricted by the small space, which is not user-friendly, especially for elderly users or those with operational difficulties; the screw-fixed structure can ensure installation stability, but each time the battery is replaced, the screws must be tightened with tools, which is cumbersome, not only prolonging the operation time, but also potentially affecting the normal use of the product due to lost or stripped screws.
[0003] Furthermore, some timer switches, in pursuit of a compact design, have button batteries directly soldered or clipped onto the circuit board. Replacing the battery requires disassembling the circuit board, which not only increases the difficulty of operation for users but also may damage circuit components due to improper handling, significantly reducing the product's lifespan. Additionally, traditional battery mounting structures often place the battery compartment on the back or bottom of the product. In installation environments with limited space (such as recessed or wall-mounted installations), battery replacement requires removing the entire timer switch from its mounting location, further complicating maintenance.
[0004] Therefore, designing a battery mounting structure that is easy to operate and stable and reliable without disassembling the entire device has become a key technical issue in improving the user experience of timer switch products. Utility Model Content

[0029] This invention provides a battery mounting structure for a timer switch.
[0030] In this embodiment, refer to Figure 1-6The battery mounting structure of the timer switch includes a bottom shell 1, a cover plate 2, a circuit board 3 and a button battery 4, and also includes a drawer-type battery box 5. The drawer-type battery box 5 has an elastic limiting plate 6 on its side, and the bottom shell has a drawer socket 7 on its side. The drawer-type battery box is inserted into the drawer socket and is restricted in the drawer socket by the elastic limiting plate. The circuit board has an electrical contact piece 8 on one side of the drawer socket.
[0031] A spacer groove 9 is provided between the elastic limiting plate and the drawer-type battery box, and a limiting step 10 is provided on the outer wall of the elastic limiting plate.
[0032] A fixed step 11 adapted to the limiting step is provided on the inner wall of the outer shell at the drawer slot.
[0033] The aforementioned technical solution comprises a bottom shell, a cover plate, a circuit board, a button battery, and a newly added drawer-type battery compartment. The drawer-type battery compartment has a flexible limiting plate on its side, and the bottom shell has a drawer slot on its side. After the battery compartment is inserted into the slot, it is secured by the limiting step on the flexible limiting plate engaging with the fixed step on the inner wall of the outer shell at the slot. Simultaneously, the circuit board has an electrical contact piece on the drawer slot side for connecting to the button battery. A spacer groove exists between the flexible limiting plate and the battery compartment. The drawer-type design allows the battery compartment to be inserted or removed without disassembling the entire device. Combined with the limiting structure of the flexible limiting plate, it ensures the stability of the installation. The spacer groove provides deformation space for the flexible limiting plate, facilitating operation. The electrical contact piece ensures a stable electrical connection between the battery and the circuit board, improving the convenience of battery replacement and the reliability of the structure.
[0034] Specifically, the side of the elastic limiting plate is provided with an inlet inclined surface 12, and the side wall of the fixed step is provided with a matching inclined surface 13 that is adapted to the inlet inclined surface 12.
[0035] In this embodiment, a guide slope is provided on the side of the elastic limiting plate, and a mating slope is provided on the side wall of the corresponding fixed step. When the battery box is inserted into the drawer slot, the guide slope guides the insertion, making the insertion process smoother. After insertion, the guide slope and the mating slope come into contact with each other, improving the stability of the connection.
[0036] Specifically, the drawer-type battery box includes a cover 14 located at the opening of the drawer socket and a battery compartment 15 for installing button batteries. The battery compartment 15 is provided with a battery cavity 16 for accommodating button batteries. The bottom of the cover is provided with a raised step 17, and the bottom shell is provided with a positioning step 18 that matches the raised step.
[0037] In this embodiment, the drawer-type battery box consists of a cover and a battery compartment. The battery compartment contains a battery cavity for accommodating button batteries. The raised step at the bottom of the cover is adapted to the positioning step inside the bottom shell. The raised step and the positioning step mutually limit each other, thereby restricting the insertion stroke of the drawer-type battery box.
[0038] Specifically, the drawer opening has pull-out clearance notches 19 on both the top and bottom sides.
[0039] In this embodiment, pull-out clearance notches are provided on the upper and lower sides of the drawer opening, providing operating space for fingers or tools and facilitating the pull-out operation of the drawer-type battery box.
[0040] Specifically, the end of the elastic limiting plate is provided with two operating steps 20.
[0041] In this embodiment, two operating steps are provided at the end of the elastic limiting plate, which makes it convenient for the user to press the elastic limiting plate with their fingers or tools to separate the limiting steps from the fixed steps, thereby pulling out the battery box.
[0042] Specifically, the bottom of the battery compartment is provided with an elastic support piece 21 to support the button battery.
[0043] In this embodiment, an elastic support piece is provided at the bottom of the battery compartment. The elastic support piece can lift the button battery, ensuring that the button battery and the electrical contact piece are in close contact. The elasticity of the elastic support piece can compensate for slight deformation of the button battery due to size errors or during use, ensuring that the button battery and the electrical contact piece always have good contact, reducing power supply failures caused by poor contact, and improving the stability of the timer switch operation.
[0044] Specifically, the bottom of the battery compartment is provided with a slot 22 for inserting an elastic support piece, the elastic support piece is provided with a through hole 23 in the middle, and support springs 24 are evenly distributed around the through hole, and the support springs have a support portion 25 protruding from the surface of the elastic support piece.
[0045] In this embodiment, the slot facilitates the installation and replacement of the elastic support piece. The elasticity of the support spring allows the support portion to apply a stable supporting force to the button battery, and the design enhances the elastic performance and uniformity of the support piece.
