The buttons on intercoms are usually conventional mechanical buttons, which transmit mechanical energy to the buttons by pressing the faceplate. There are often uneven key gaps, inconsistent feel, and problems with not being able to reset after being pressed. Utility Model Content

[0003] This application provides a reset structure to solve the problems existing in related technologies. The technical solution is as follows:

[0004] This application provides a button reset structure, including:

[0005] The housing has an assembly groove.

[0006] The button is located inside the housing;

[0007] The cover is mounted on the shell.

[0008] The protrusion is set on the cover and is set in the mounting groove. When one side of the cover is pressed, the protrusion moves relative to the mounting groove.

[0009] The support assembly is mounted on the housing. When one side of the cover is pressed, the support assembly deforms. When the cover is released, the support assembly returns to its original position.

[0010] In one implementation, it further includes:

[0011] The pressure block is located on the side of the cover away from the protrusion, and the pressure block corresponds to the button.

[0012] In one implementation,

[0013] Supporting components include:

[0014] Spring clip, the spring clip is set on the housing;

[0046] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0047] Figures 1-3 This diagram illustrates a structural diagram of a button reset structure 100 according to an embodiment of this application. Figures 1-3 As shown, the reset structure 100 may include:

[0048] Housing 110, housing 110 having an assembly groove 111;

[0049] Button 120 is disposed inside housing 110;

[0050] Cover 130, cover 130 is disposed on housing 110;

[0051] A protrusion 140 is provided on the cover 130 and is located in the mounting groove 111. When one side of the cover 130 is pressed, the protrusion 140 moves relative to the mounting groove 111.

[0052] Support component 150 is disposed on housing 110. When one side of cover 130 is pressed, support component 150 deforms. When cover 130 is released, support component 150 returns to its original position.

[0053] In this embodiment, the cover 130 is installed on the housing 110. By pressing the cover 130 to contact the button 120, the button 120 can be controlled through the cover 130. When the cover 130 is installed on the housing 110, the cover 130 is located in the mounting groove 111. When the cover 130 is pressed, the protrusion 140 moves in the mounting groove 111. At the same time, the support component 150 deforms. When the cover 130 is released, the support component 150 returns to its original position and provides support for the cover 130.

[0054] By setting the support component 150, when the cover 130 is pressed, the support component 150 deforms and when the cover 130 is released, the support component 150 returns to its original position, thus supporting the cover 130 and preventing the cover 130 from not springing back in time after being pressed. Compared with the traditional method of using the button 120, which is more likely to generate friction between the cover 130 and the housing 110 when pressed, this method reduces friction during the pressing process and enhances the pressing feel.

[0055] like Figure 3 As shown, in one embodiment, it further includes:

[0056] The pressing block 160 is located on the side of the cover 130 away from the protrusion 140, and the pressing block 160 corresponds to the button 120.

[0057] In this embodiment, by setting the pressing block 160, when the cover 130 is pressed, the pressing rod contacts the button 120, thereby causing the pressing block 160 to trigger the button 120;

[0058] Furthermore, the housing 110 has a hole that fits the pressure block 160, so that the pressure block 160 can pass through the housing 110 and contact the button 120.

[0059] like Figure 2 As shown, in one embodiment,

[0060] Support component 150 includes:

[0061] Spring 151 is disposed on housing 110;

[0062] Protrusion 152 is provided on the spring piece 151.

[0063] In this embodiment, when the cover 130 is pressed, the spring 151 deforms, thereby causing the pressing block 160 to contact the button 120. When the cover 130 is released, the spring 151 returns to its original position, so that the cover 130 returns to its original position and the pressing block 160 separates from the button 120. The spring 151 enhances the feel when the cover 130 is pressed down, and the protrusion 152 enhances the feel when the cover 130 is pressed down.

[0064] Furthermore, protrusion 152 has a hemispherical structure;

[0065] The cover 130 has a groove 131 that matches the protrusion 152. When the cover 130 is installed on the housing 110, the protrusion 152 is located in the groove 131.

[0066] By adapting the protrusion 152 to the groove 131, the friction force when the cover 130 is pressed down is reduced, thereby improving the feel when the cover 130 is pressed down.

[0067] like Figures 2-3 As shown, in one embodiment, it further includes:

[0068] A limiting plug 170 is provided on the cover 130, and the housing 110 has a slot that is adapted to the limiting plug 170.

[0069] In this embodiment, when the cover 130 is installed on the housing 110, the limiting plug 170 is inserted into the slot, thereby allowing the cover 130 to be installed on the housing 110. The limiting plug 170 has a plug rod and a protrusion. When the cover 130 is installed on the housing 110, the protrusion fits against the housing 110.

[0070] Furthermore, the limiting plug 170 on the cover 130 can also be set in the form of a spring, so that the cover 130 can be tilted on the housing 110, and the opening and closing of the button 120 can be determined by the tilt angle of the cover 130.

[0071] like Figures 2-3 As shown, in one embodiment,

[0072] Limit plug-in 170 is an elastic component.

[0073] In this embodiment, the limiting plug 170 is an elastic element, that is, the plug rod on the limiting plug 170 is an elastic element, and one side of the protrusion is a slope. When the cover 130 is installed on the upper part, the elastic element is deformed under the action of the slope, which facilitates the installation of the cover 130 and the shell 110.

[0074] In one implementation,

[0075] The size of the mounting groove 111 is larger than the size of the protrusion 140.

[0076] In this embodiment, the size of the mounting groove 111 is larger than the size of the protrusion 140, thereby ensuring that when the cover 130 is moved, the protrusion 140 can move within the mounting groove 111, making it easier to press the cover 130 to activate the button 120.
