[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other.

[0043] Please combine them together Figures 1 to 4 , Figure 9 and Figure 10The doorbell call device provided in this embodiment of the present invention will now be described. The doorbell call device includes a call device body 10, a battery 20, and a housing assembly 30. The battery 20 is electrically connected to the call device body 10 and is configured to supply power to the call device body 10. The housing assembly 30 encloses and forms an installation space 100, in which the call device body 10 and the battery 20 are installed. The installation space 100 is provided with a first clamping wall 40 and a second clamping wall 50, which are spaced apart from the housing assembly 30 and clamp the battery 20. The installation space 100 is also provided with a support platform 31, which supports the battery 20 and the housing assembly 30. The side of the support platform 31 facing the battery 20 has a groove 200 and a through groove 300. The support platform 31 provides support for the battery 20 and also enhances the structural strength of the housing assembly 30, preventing the groove 200 and through groove 300 from reducing the strength of the housing assembly 30. In this embodiment of the invention, there are multiple grooves 200, which are relatively evenly distributed on the support platform 31. This ensures that the support platform 31 provides more uniform support for the battery 20 and guarantees the stability of the battery 20's position. Furthermore, it reduces the contact area between the battery 20 and the support platform 31, and increases the contact area between the battery 20 and the air within the grooves 200. The through groove 300 penetrates the support platform 31 and the outer casing assembly 30, communicating with the installation space 100, and partially exposes the battery 20 within the outer casing assembly 30.

[0044] Implementing this utility model embodiment will have the following beneficial effects: The doorbell caller of the above solution, by providing a support platform 31 for supporting the battery 20 on the outer shell assembly 30, and utilizing the groove 200 provided on the support platform 31, can reduce the area of ​​direct contact between the support platform 31 and the battery 20, so that the heat generated by the battery 20 can be diffused into the air within the groove 200, avoiding heat accumulation and allowing heat to be diffused only through the outer shell assembly 30. Furthermore, the heat can also be diffused to the outside of the outer shell assembly 30 through the through groove 300, further preventing heat accumulation and thus preventing the outer shell assembly 30 from overheating due to heat accumulation. In addition, the provision of the first clamping wall 40 and the second clamping wall 50 can fix the battery 20, ensuring the stability of the power supply from the battery 20 to the caller body 10. Moreover, since the first clamping wall 40 and the second clamping wall 50 are spaced apart, the battery 20 has a larger contact area with the air within the installation space 100, which also improves the heat dissipation effect of the battery 20.

[0045] Please combine them together Figures 1 to 3 , Figure 5 and Figure 10The pager body 10 includes a circuit board 11, an antenna 12, multiple light-emitting lamps 13, and a buzzer 14.

The light-transmitting component 35 also includes a light-transmitting sheet 351 located on the front side of the sealing plate 34. The sealing plate 34 has light-transmitting holes 400 corresponding to the digital tube. When assembled, the rear end of the digital tube surrounds the light-emitting lamp body 13. When the light-emitting lamp body 13 is activated, light passes through the digital tube and the light-transmitting holes 400 and through the light-transmitting sheet 351. Then, the circuit board 11 can light up or turn off each light-emitting cavity of the digital tube to form specific numbers or letters. The light-transmitting component 35 also includes a light-transmitting protective plate 352 covering the light-transmitting sheet 351. The antenna 12 can receive wireless control signals to control the buzzer 14 to emit a sound via the circuit board 11 to indicate the arrival of guests. The wireless control signal can be emitted via a doorbell button located on the outside of the house.

[0046] In the exemplary embodiments, please refer to Figure 2 , Figure 4 and Figure 6 The first clamping wall 40 includes a first clamping portion 41 and a second clamping portion 42.

[0047] The second clamping wall 50 includes a third clamping portion 51 and a fourth clamping portion 52, which are arranged at an angle. The third clamping portion 51 is circumferentially fitted to the battery 20, and one side of the third clamping portion 51 is connected to the housing assembly 30, while the other side has a recessed groove 500. The recessed groove 500 increases the circumferential area of ​​the battery 20 exposed in the installation space 100, facilitating contact between fingers and the battery 20 during installation and removal, thus simplifying the process. Furthermore, the recessed groove 500 enhances the elastic deformation capability of the third clamping portion 51, allowing it to elastically abut against the battery 20 and improving the clamping stability. The fourth clamping portion 52 is circumferentially fitted to the battery 20 and has multiple bends 521 to form a gap space 600 between the fourth clamping portion 52 and the battery 20. By incorporating multiple bends 521, the elastic deformation capability of the fourth clamping part 52 can be enhanced, allowing the fourth clamping part 52 to elastically abut against the battery 20, thereby improving the clamping stability of the battery 20. Furthermore, the multiple bends 521 can reduce the contact area between the fourth clamping part 52 and the battery 20, and increase the contact area between the battery 20 and the air in the space 600, facilitating the dissipation of heat generated by the battery 20.

[0048] In the exemplary embodiments, please refer to Figure 3 , Figure 4 , Figures 6 to 8 , Figure 11 and Figure 12 The outer casing assembly 30 is provided with a protrusion 36, which protrudes outward from the side of the outer casing assembly 30 away from the mounting space 100 and forms a receiving groove 700 communicating with the mounting space 100.

The doorbell call device is also provided with a power control board 60. The power control board 60 is mounted in the receiving groove 700 and is electrically connected to the battery 20. By providing the receiving groove 700, the contact area between the power control board 60 and the battery 20 can be reduced, which facilitates heat dissipation of the battery 20 and the power control board 60. A power switch 61 is provided on the power control board 60, and the power switch 61 is exposed in the through hole 701, which facilitates external control of the power switch 61. The power switch 61 is configured to control the battery 20 to supply power to the call device body 10 through the power control board 60. In this embodiment of the present invention, the power switch 61 is a sliding switch that can slide relative to the protrusion 36 along the through hole 701.

[0049] In the exemplary embodiments, please refer to Figure 4 and Figure 6The housing assembly 30 is provided with multiple spaced mounting walls 70 surrounding the power control board 60. A first notch 800 is provided on the side of each mounting wall 70 facing the power control board 60. The first notch 800 forms a clamping surface and a supporting surface on the mounting wall 70. The circumference of the power control board 60 fits against the clamping surface, and one side of the power control board 60 is supported on the supporting surface, spaced apart from the protrusion 36. This arrangement of the mounting walls 70 improves the positional stability of the power control board 60, ensuring stable connection with the battery 20. Furthermore, it prevents the power control board 60 from directly connecting to the housing assembly 30, increasing the contact area between the power control board 60 and the air, ensuring effective heat dissipation. Similarly, heat can also dissipate to the outside through the through-hole 701.

[0050] In an exemplary embodiment, such as Figure 8 As shown, protrusion 36 is provided with interface 900, which communicates with receiving groove 700.
