All elements required by the doorbell are arranged in the corresponding areas of the shell and the key plate, and plastic elements do not need to be arranged around the key plate. The size of the key plate can be further increased, which is conducive to the identification of the key plate area by the user and the interactive operation of the doorbell.

Description

Technical Field

[0001] This disclosure relates to the field of security equipment technology, and in particular to a doorbell. Background Technology

[0002] With the development of technology, doorbells have gradually combined cameras and buttons. The camera is an electronic device that automatically captures the situation outside the door. When outsiders arrive at the door, they can notify the people inside the door through the doorbell button. Therefore, the larger button size is conducive to outsiders quickly and accurately identifying the button and interacting with it.

[0003] In related technologies, the doorbell housing is perforated to house the doorbell button, and plastic components are placed around the doorbell button to fix, limit, and guide it.

[0004] In the aforementioned doorbell, the doorbell consists of two parts: a doorbell button and a plastic component. Since the plastic component needs to occupy a certain space around the doorbell button, the size of the doorbell button is limited, making it difficult for users to identify the doorbell button area and making it inconvenient for users to interact with the doorbell. Utility Model Content

[0005] This disclosure provides a doorbell that solves the aforementioned technical problems in related technologies. The technical solution is as follows:

[0006] The doorbell includes a housing, a circuit board, and a button panel;

[0007] The housing has a doorbell area, and the doorbell area has a first through hole;

[0008] The circuit board is connected to the housing, and the circuit board has a doorbell switch, which is opposite to the first through hole;

[0009] The inner wall of the button panel has a first protrusion, the inner wall is connected to the doorbell area, the first protrusion is opposite to the first through hole, and is used to press the doorbell switch.

[0010] In some possible implementations, the doorbell area has a snap-fit ​​hole, and the inner wall has a snap fastener that snaps into the snap-fit ​​hole.

[0011] In some possible implementations, the doorbell further includes an elastic element connected to the doorbell area and abutting against the inner wall.

[0012] In some possible implementations, the elastic element has a second through hole, and the inner wall has a positioning element located within the second through hole.

[0013] In some possible implementations, the elastic element is a cantilever mechanism, with a first end connected to the doorbell area, a second end abutting against the inner wall, and the second through hole located at the second end of the cantilever mechanism.

[0014] In some possible implementations, there are multiple elastic elements, which are evenly distributed in the doorbell area.

[0015] In some possible implementations, the number of elastic elements is four, and the four elastic elements are symmetrically distributed along the center of the first through hole.

[0016] In some possible implementations, the number of snap-fit ​​holes is four, the snap-fit ​​holes are located on the side of the elastic element away from the first through hole, and the snap-fit ​​holes and the elastic elements correspond one-to-one.

[0017] In some possible implementations, the housing has a limiting groove and the inner wall has a limiting protrusion that is adapted to the limiting groove.

[0018] In some possible implementations, the limiting protrusion includes a first limiting protrusion and a second limiting protrusion, the first limiting protrusion being located at the edge of the doorbell area, and the second limiting protrusion being located between the first limiting protrusion and the first protrusion.

[0019] The beneficial effects of the technical solution provided in this disclosure include at least the following:

[0020] In this disclosure, the keypad is connected to the housing by connecting the inner wall of the keypad to the doorbell area of ​​the housing. The first protrusion presses on the doorbell switch by having both the first protrusion and the doorbell switch opposite to the first through hole. All the components required for the doorbell are set in the corresponding areas of the housing and the keypad, eliminating the need for plastic components around the keypad. The size of the keypad can be further increased, which is beneficial for users to identify the keypad area and to operate the doorbell interactively.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0035] This disclosure provides a doorbell, referring to... Figure 1 As shown, the doorbell includes a housing 1, a circuit board 2, and a button board 3.

[0036] The housing 1 has a doorbell area 1a, the doorbell area 1a has a first through hole 11, the circuit board 2 is connected to the housing 1, the circuit board 2 has a doorbell switch 21, the doorbell switch 21 is opposite to the first through hole 11, the inner wall 3a of the button plate 3 has a first protrusion 31, the inner wall 3a is connected to the doorbell area 1a, the first protrusion 31 is opposite to the first through hole 11, and is used to press the doorbell switch 21.

[0037] The button panel 3 is connected to the doorbell area 1a of the housing 1 by connecting the inner wall 3a of the button panel 3 to the doorbell area 1a of the housing 1. The first protrusion 31 presses against the doorbell switch 21 by aligning the first protrusion 31 and the doorbell switch 21 with the first through hole 11. In this way, all the components required for the doorbell are located in the corresponding areas of the housing 1 and the button panel 3, eliminating the need for plastic components around the button panel 3. This allows for a larger button panel 1, which in turn facilitates user identification of the area where the button panel 3 is located and interactive operation of the doorbell.

[0038] This disclosure does not specifically limit the material of the keypad 3, such as metal or plastic. The material can be matched and set according to parameters such as the strength requirements, appearance, and manufacturing cost of the keypad 3. In subsequent embodiments, a plastic component is used as an example for illustration, but this disclosure is not limited thereto.

[0039] In some embodiments, refer to Figure 1 As shown, the doorbell area 1a has a snap-fit ​​hole 12, and the inner wall 3a has a snap fastener 32, which snaps into the snap-fit ​​hole 12.

[0040] The assembly method, which uses snap-fit ​​32 and snap-fit ​​holes 12, enables the connection between the button panel 3 and the housing 1. Furthermore, this snap-fit ​​assembly method is relatively simple, simplifying the assembly process and improving the assembly efficiency of the doorbell.

[0041] In some embodiments, refer to Figure 1 As shown, the doorbell also includes an elastic element 4, which is connected to the doorbell area 1a and abuts against the inner wall 3a. The elastic element 4 is a component capable of elastic deformation and generating elastic force. When the button panel 3 is not pressed by the user, the elastic element 4 undergoes a certain elastic deformation and generates a certain rebound force. At the same time, the inner wall 3a is connected to the doorbell area 1a, thereby ensuring the connection between the button panel 3 and the housing 1.

[0042] When the button panel 3 is pressed by the user, the elastic deformation of the elastic element 4 increases further and generates a greater rebound force. Thus, when the user releases the pressure on the button panel 3, under the action of the rebound force of the elastic element 4, the button panel 3 moves to the side away from the doorbell switch 21 to the starting position of the button panel 3.

[0043] In some embodiments, refer to Figure 1 As shown, the elastic member 4 has a second through hole 41, and the inner wall 3a has a positioning member 33, which is located inside the second through hole 41.

[0044] The cooperation between the positioning component 33 and the second through hole 41 is beneficial to the assembly of the buckle 32 and the snap-fit ​​hole 12, and also helps to reduce the risk of misalignment or shaking of the keypad 3.

[0045] In some embodiments, refer to Figure 2 As shown, the elastic element 4 is a cantilever mechanism. The first end of the cantilever mechanism is connected to the doorbell area 1a, the second end of the cantilever mechanism abuts against the inner wall 3a, and the second through hole 41 is located at the second end of the cantilever mechanism.

[0046] First, compared to coil springs, the cantilever structure is more compact and can be integrated into a limited space, making it suitable for the internal installation space of doorbells. Second, the cantilever mechanism has high rigidity perpendicular to the bending direction and strong resistance to lateral interference. Third, the cantilever mechanism has no relatively sliding parts inside, which can avoid frictional wear and extend the service life of the elastic element 4.

[0047] In some embodiments, the elastic element 4 is fixedly connected to the inner wall 3a. This can prevent relative sliding between the button plate 3 and the elastic element 4 during the process of the button plate 3 squeezing the elastic element 4, thereby reducing the wear or deformation of the inner wall 3a or the elastic element 4 caused by friction.

[0048] For example, both the elastic element 4 and the button plate 3 are plastic components. After the positioning element 33 passes through the second through hole 41, the elastic element 4 and the positioning element 33 can be connected by heat fusion, thereby ensuring the fixed connection between the elastic element 4 and the button plate 3.

[0049] In some embodiments, refer to Figure 2 As shown, there are multiple elastic elements 4, which are evenly distributed in the doorbell area 1a. On the one hand, by setting multiple elastic elements 4, stress concentration at one elastic element 4 can be avoided when the user presses the button panel 3; on the other hand, when one or more elastic elements 4 fail, the multiple elastic elements 4 scheme can ensure that the button panel 3 can still be subjected to a certain rebound force, thereby ensuring that the button panel 3 can gradually return to the starting position.

[0050] In some embodiments, refer to Figure 1 As shown, there are four elastic elements 4, which are symmetrically distributed along the center of the first through hole 11. For example, the doorbell area 1a is a rectangular area, and the four elastic elements 4 can be located at the four corners of the doorbell area 1a. In this way, the four elastic elements 4 ensure that when the user presses the button plate 3, one or more elastic elements can generate a rebound force to make the button plate 3 return to the starting position, and also avoid the increase in installation space caused by the setting of more elastic elements 4.

[0051] In some embodiments, refer to Figure 1 As shown, there are four snap-fit ​​holes 12. The snap-fit ​​holes 12 are located on the side of the elastic member 4 away from the first through hole 11, and the snap-fit ​​holes 12 and the elastic member 4 correspond one-to-one.

[0052] In this way, when the user presses the edge of the button panel 3, the elastic element 4 on the pressing side deforms under force. The snap-fit ​​position of the buckle 32 away from the pressing side and the snap-fit ​​hole 12 is the fulcrum, and the user's pressing position is the lever's force application point. This causes the first protrusion 31 located between the fulcrum and the force application point to gradually approach and squeeze the doorbell switch 21, thereby realizing the doorbell's ringing function.

[0053] The elastic element 4 on the pressing side and the snap-fit ​​structure on the non-pressing side ensure the accuracy of the ringing function when the edge of the button panel 3 is pressed. That is, when the user presses the edge of the button panel 3, the doorbell switch 21 can be triggered accurately and quickly, thereby improving the triggering feel and triggering effect of the button panel 3.

[0054] In some embodiments, refer to Figure 2 and Figure 3 As shown, the housing 1 has a limiting groove 13, and the inner wall 3a has a limiting protrusion 34, which is adapted to the limiting groove 13. On the one hand, the setting of the limiting protrusion 34 can enhance the structural strength of the keypad 3 and prevent the keypad 3 from deforming, cracking, or falling off due to external pressure. On the other hand, the limiting protrusion 34 and the limiting groove 13 cooperate with each other, and on the basis of the cooperation between the positioning member 33 and the second through hole 41, further constrain the relative position of the inner wall 3a and the doorbell area 1a, reducing the risk of the keypad 3 shaking, misaligning, or making abnormal noises.

[0055] In some embodiments, refer to Figure 3 As shown, the width L of the limiting protrusion 34 is 0.5mm-1.5mm. If the width of the limiting protrusion 34 is too small (L<0.5mm), the limiting protrusion 34 will have a smaller effect as a reinforcing rib, and will not be able to effectively guarantee the structural strength of the button plate 3, nor will it be able to cooperate well with the limiting groove 13 to constrain the relative position of the inner wall 3a and the doorbell area 1a. If the width of the limiting protrusion 34 is too large (L>1.5mm), on the one hand, it will increase the amount of material used in the button plate 3 and increase the manufacturing cost; on the other hand, the cooperation structure between the limiting protrusion 34 and the limiting groove 13 will occupy a large space inside the doorbell, which is not conducive to the layout and installation of other components.

[0056] In some embodiments, refer to Figure 3 As shown, the limiting protrusion 34 includes a first limiting protrusion 341 and a second limiting protrusion 342. The first limiting protrusion 341 is located at the edge of the doorbell area 1a, and the second limiting protrusion 342 is located between the first limiting protrusion 341 and the first protrusion 342.

[0057] In this way, the first limiting protrusion 341 and the second limiting protrusion 342 are respectively distributed at various positions on the inner wall 3a, so that the limiting protrusion 34 is subjected to uniform force as a whole, and the shaking of the button plate 3 in all directions is well constrained.

[0058] In some embodiments, refer to Figure 2 As shown, the edge of the button panel 3 has a rounded corner structure 3b. The rounded corner structure 3b allows for a smooth transition between different sidewalls of the button panel 3, avoiding the risk of users being stabbed or scratched by sharp parts of the doorbell during use, thus improving the safety of the doorbell.
