[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The embodiment of the present application provides an integrated key structure, which can solve the problems in the prior art of high production cost and easy falling of small debris between the display and the key structure.

[0027] like Figure 1 and Figure 2 As shown, the present application provides an embodiment of an integrated key structure, which is arranged in the slot 3 of the display housing 1, and the key structure includes a key elastic arm 204, one end of which is integrally formed with the display housing 1, and the other end of which extends to form a key portion 203, and the side wall of the key portion 203 has a key enclosing rib 201, which is located in the slot 3 of the display housing 1, shielding the slot 3, preventing small debris from easily falling into the display and causing a short circuit of the key structure, and extending the service life of the key structure. Specifically, the key enclosing rib 201 semi-encloses and surrounds the key portion 203, and except for the portion where the key enclosing rib 201 and the key elastic arm 204 are connected, the components in the slot 3 can be effectively shielded.

[0028] In this embodiment, with the direction of the key structure facing the user's finger as the top, the key closing rib 201 is equivalent to being set below the slot 3, shielding the slot 3, so that the outside cannot directly see the components exposed below the slot 3 through the slot 3, preventing small debris from easily falling into the display and causing a short circuit of the key structure, thereby extending the service life of the key structure. In addition, one end of the key elastic arm 204 is integrally formed with the display housing 1, reducing production costs. When the key part 203 is pressed, the key closing rib 201 does not deform, the key closing rib 201 shields the slot 3, the key part 203 drives the key elastic arm 204 to undergo elastic deformation relative to the display housing 1, and the key structure takes effect. When the key part 203 is released, the key part 203 and the key elastic arm 204 return to their original positions.

[0029] It should be noted that the integrated key structure means that the display housing and the key structure share a set of molds. In the related art, what affects the gap between the display housing and the key structure in the integrated key structure is the connection method between the molds. The traditional integrated key structure adopts a penetration structure. The penetration means that when the mold is closed, the surface of a certain part of the upper mold core is tightly attached to the surface of a certain part of the corresponding lower mold core, so that a hole is formed on the product. The gap between the key structure and the display housing is large, and it is easy to drop small debris into the display. The integrated key structure in the embodiment of the present application adopts an insertion structure. The insertion means that the upper mold core or the lower mold core extends all the way to the opposite side and passes through the opposite mold core to form a hole. The gap between the key structure and the display housing 1 is small. Since the key closing rib 201 is arranged around the key part 203, the key closing rib 201 shields the gap to prevent small debris from falling into the display.

[0030] In some embodiments, the button portion 203 protrudes from the outer surface of the display housing 1 , and a plurality of anti-slip bumps are provided on the contact surface of the button portion 203 with the hand to facilitate pressing the button portion 203 .

[0031] When the button part 203 is not pressed, the button part 203 protrudes from the outer surface of the display housing 1, which is convenient for contacting the contact surface of the hand. When the button part 203 is pressed, the button part 203 drives the button elastic arm 204 to undergo elastic deformation relative to the display housing 1. When the button part 203 is released, the button part 203 and the button elastic arm 204 return to their original positions.

[0032] Furthermore, multiple of the above-mentioned anti-slip protrusions are connected to form a stepped shape, and two adjacent anti-slip protrusions form a step. The button part 203 includes multiple steps. When the button part 203 needs to be pressed, by pressing one or more steps, the button part 203 can be pressed down, and the button elastic arm 204 can be driven to undergo elastic deformation relative to the display housing 1.

[0033] like Figure 2 and Figure 3 As shown, further, the side wall of the button part 203 extends into the slot 3, and the button closing rib 201 surrounds the side wall. The display housing 1 is provided with a slot 3, and the button part 203 is a rectangular structure. Except for one side connected to the button elastic arm 204, the other three sides of the button part 203 extend into the slot 3. The other three side walls of the button part 203 are provided with a button closing rib 201. The button closing rib 201 shields the gap under the slot 3 to prevent small debris from easily falling into the display and causing a short circuit of the button structure, thereby extending the service life of the button structure.

[0034] like Figure 1 and Figure 4 As shown, in some embodiments, the key elastic arm 204 is a strip-shaped flat structure, one short side of the flat structure is integrally formed with the display housing 1, and the other short side of the flat structure extends to form the key portion 203. One short side of the flat structure is integrally formed with the display housing 1, and the display housing 1 and the key structure can be made with one set of molds, reducing production costs. The other short side of the flat structure extends to form the key portion 203, and the key portion 203 and the key elastic arm 204 are also an integral structure. When the key portion 203 is pressed, the key elastic arm 204 also undergoes elastic deformation relative to the display housing 1.

[0035] Furthermore, the outer surface of the button elastic arm 204 is lower than the button portion 203 . When the button portion 203 is pressed, the button portion 203 drives the button elastic arm 204 to elastically deform relative to the display housing 1 .

[0036] Furthermore, the side wall of the key elastic arm 204 is also provided with a key closing rib, which is located in the slot 3 of the display housing 1 to cover the slot 3. One side of the key elastic arm 204 is integrally formed with the display housing 1, and the other two sides are provided with gaps with the display housing 1. The key closing rib on the side wall of the key elastic arm 204 prevents small debris from falling into the display.

[0037] like Figure 1 and Figure 4 As shown, further, the width of the button portion 203 is smaller than the width of the button elastic arm 204. When the button portion 203 is pressed, the short side of the button portion 203 drives the button elastic arm 204 to undergo elastic deformation.

[0038] like Figure 1 and Figure 4As shown, in some embodiments, the outer surface of the above-mentioned key elastic arm 204 is provided with a buckle 205 connected to the display bracket, and the buckle 205 is fixed to the display bracket, so that the display housing 1 is installed on the display bracket, so the key elastic arm 204 will not be exposed to the outside. In this way, only the key part 203 is exposed to the outside, and the side wall of the key part 203 is provided with a key closing rib 201, so that the slot 3 can be covered, which can prevent small debris from easily falling into the display and causing a short circuit of the key structure, thereby extending the service life of the key structure.

[0039] like Figure 2 and Figure 3 As shown, in some embodiments, the key structure further includes a key contact 202, which is located at one end of the side wall of the key portion 203 facing the inside of the display, and the key contact 202 is located at one end away from the key elastic arm 204, that is, located at the lower end of the rear side wall of the key portion 203. Taking the direction toward the user's finger as the top, the key enclosed rib 201 is equivalent to being arranged below the slot 3. The key portion 203 is a rectangular structure, and three sides of the key portion 203 are connected to the key enclosed rib 201, and the other side extends to form one end of the key elastic arm 204. The key contact 202 is located at the short side away from the key elastic arm 204 and faces the inside of the display. When the key portion 203 is pressed, the key contact 202 is connected to the circuit structure inside the display, and the function key represented by the key structure comes into play, such as adjusting the volume or adjusting the menu options.

[0040] In the second aspect, a use embodiment of an integrated key structure is provided. When the key part 203 is pressed, the key part 203 moves toward the inside of the display relative to the display housing 1, and the key closing rib 201 of the side wall of the key part 203 does not undergo elastic deformation, and shields the slot 3, thereby reducing the gap between the key part 203 and the slot 3, and the key elastic arm 204 undergoes elastic deformation relative to the display housing 1. When the key part 203 is released, the key part 203 and the key elastic arm 204 return to their original positions.

[0041] In summary, the present application forms a button portion 203 by integrally forming one end of the button elastic arm 204 with the display housing 1, and extending the other end. The side wall of the button portion 203 has a button closing rib 201. The button closing rib 201 is located in the slot 3 of the display housing 1, semi-enclosing the button portion 203. Except for the portion where the button closing rib 201 and the button elastic arm 204 are connected, the slot 3 is effectively shielded to prevent small debris from easily falling into the display and causing a short circuit in the button structure, thereby extending the service life of the button structure. At the same time, the button structure and the display housing 1 are integrally formed and share a set of molds, thereby reducing production costs.
