Electronic doorbells are devices that can make sounds to remind the owner of guests. The use of doorbells improves the safety and privacy of home and office work, and is loved by the general public.
[0003] Electronic doorbells generally include outdoor units and outdoor units, both of which are composed of a base and a shell, as well as various electronic components arranged inside the shell. Regardless of whether it is an outdoor unit or an outdoor unit, various buttons are designed, including switch buttons, ringing buttons, sound adjustment buttons, and other function adjustment buttons to meet the needs of users. At present, most doorbells use mechanical buttons, especially the ringing buttons of outdoor units. Because they need to be pressed repeatedly during long-term use, in order to ensure that the buttons can still be reset normally, the current means are generally to install a reset spring inside the button to cooperate with it. However, due to the small size of the reset spring, it is not convenient for workers to assemble it, resulting in special attention during the assembly process to install and fix it. The assembly process is relatively slow, and in the production process, a special production line needs to be opened to process the springs, or special springs need to be purchased from outside. However, this is not conducive to the cost control of the enterprise. Utility Model Content

[0020] Moreover, the terms "up, down, left, right, upper end, lower end, longitudinal" and the like indicating directions are all based on the posture and position of the device or equipment described in this solution during normal use.
[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0022] The doorbell external unit with a self-reset button structure in the preferred embodiment of the utility model is as follows Figure 1-3 As shown, the base 10 and the front shell 20 covered on the front side wall of the base 10 are included, and the control panel 30 is provided inside the front shell 20, the ring button body 40 is provided on the front side wall of the control panel 30, and the pressing plate 50 is provided on the front side of the ring button body 40. Specifically, the base 10, the front shell 20 and the ring button body 40 are all made of plastic. A pressing portion 51 is provided on the rear side wall of the pressing plate 50 corresponding to the ring button body 40, a boss 52 is provided on the front side wall of the pressing plate 50, a through hole 60 adapted to the boss 52 is provided on the front shell 20, and a first extension portion 53 inclined toward the control panel is also provided on the upper end of the pressing plate 50, and a second extension portion 54 is provided on the upper end of the first extension portion 53, and a fixing seat 70 is provided on the inner wall of the front shell 20, and the second extension portion 54 is detachably connected with the fixing seat 70, so as to facilitate disassembly and assembly. When assembled in place, the pressing plate 50 fits against the rear side wall of the front shell 20 to ensure the fit between the pressing plate 50 and the inner wall of the through hole 60.
[0023] The overall structure is simple and the structural implementation is easy. After assembly, the push-button plate 50 can be positioned in the through hole 60 and a reset force can be provided for the push-button plate 50 through the cooperation of the first extension portion 53, the second extension portion 54 and the fixing seat 70. Compared with the traditional reset method by adding a spring, this solution can effectively reduce the manufacturing cost. Moreover, the first extension portion 53, the second extension portion 54 and the push-button plate 50 can be integrally injection molded, which is more convenient for manufacturing and processing, and can be completed in one process through the mold.
[0024] In this embodiment, the second extension portion 54 includes an L-shaped fixing portion 541, and a connecting portion 542 connecting the lateral end 411 of the fixing portion 541 and the first extension portion 53; the longitudinal end 412 of the fixing portion 541 is detachably connected to the fixing seat 70. Specifically, the lower end of the fixing seat 70 is provided with a fixing groove 71 for the longitudinal end 412 to be inserted, and the longitudinal end 412 is interference-fitted with the fixing groove 71 to facilitate assembly and disassembly. Moreover, the L-shaped second extension portion 54 cooperates with the inclined portion to further increase the elastic deformability of the overall structure, facilitate pressing, and also reduce the risk of the inclined portion being broken.
[0025] In this embodiment, the front side wall of the fixing groove 71 is flush with the inner wall of the front shell 20. When assembled in place, the longitudinal end 412 is in contact with the rear side wall of the front shell 20, so as to completely position the boss 52 inside the through hole 60, reduce the gap between the pressing buckle plate 50 and the front shell 20, and prevent mosquitoes from entering.
[0026] In this embodiment, when assembled in place, there is a gap 100 between the lateral end 411 and the lower end of the fixing seat 70, and between the connecting portion 542 and the control board 30, so as to provide sufficient travel space for the pressing buckle plate 50 to move forward and backward.
[0027] In this embodiment, when the pressing plate 50 is pressed into place, the lateral end 411 and the connecting portion 542 respectively abut against the lower end of the fixing seat 70 and the control board 30 to prevent the pressing plate 50 from being excessively pressed.
[0028] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
