DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below through specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] refer to Figure 1 and Figure 2A hidden button instrument includes an instrument 1 and a bracket 2. Specifically, the instrument 1 includes a housing 11, a pressing block 12, a display screen 13, a PCB board 14 and a button 15. The housing 11 and the pressing block 12 can be integrally formed by liquid silicone. The pressing block 12 includes a first pressing block 122 and a second pressing block 121. The second pressing block 121 is provided with at least one reverse button 1212. The upper groove of the housing 11 is grooved (here the groove is defined as a hidden groove 111) to install the display screen 13. The hidden groove 111 and the display screen 13 are enclosed to form a sealed hidden space. A PCB board 14 is provided below the display screen 13. At least one button 15 is provided below the PCB board 14. The bottom of the button 15 abuts against the pressing block 12. The pressing block 12 cooperates with the housing 11 to seal and form a flexible connection. A partition 112 is provided at the bottom of the housing 11. The partition 112 is evenly provided with a number of through holes 1121. The bracket 2 is fixed to the bottom of the pressing block 12, and the button 15 partially passes through the through hole 1121 and abuts against the pressing block 12. When the bracket 2 presses the pressing block 12 in any free direction, the pressing block 12 is elastically deformed, and the instrument 1 moves toward the bracket 2. The pressing block 12 drives the button 15 to move toward the PCB board 14 and triggers the PCB circuit to form an electrical path.

[0026] Furthermore, a plurality of downwardly hanging buttons 15 are provided at the bottom of the PCB board 14. The PCB board 14 is fixed in the hidden space by screws. The buttons 15 include a first button 151 and a plurality of second buttons 152. The first button 151 is arranged in the middle of the PCB board 14, that is, it corresponds to the center of the display screen 13. The second buttons 152 are evenly arranged in the circumference of the PCB board 14, that is, they correspond to the edges of the display screen 13. The buttons 15 are adapted to the through holes 1121 of the partition 112. A pressing block 12 is provided at the bottom of the partition 112. The buttons 15 partially penetrate the through holes 1121 and abut against the pressing block 12.

[0027] Furthermore, the second pressing block 121 includes a connecting block 1211 and a plurality of reverse buttons 1212 formed by extending the connecting block 1211 toward the periphery. The connecting block 1211 is coaxially fixed to the first pressing block 122. The reverse button 1212 and the second button 152 are adapted and abutted. The first pressing block 122 and the first button 151 are adapted and abutted or separated. The height of the reverse button 1212 is less than the height of the first pressing block 122, so as to prevent accidental touches, improve the rationality of the design, and at the same time, improve the accuracy of triggering the button 15.

[0028] Specifically, the bracket 2 includes a main body, the two wings of the main body are straight sections, there is a gap between the reverse button 1212 and the main body and they form abutment when pressed, specifically, the reverse button 1212 abuts against the straight section of the main body; the main body is bent toward the middle to form a fixed cavity 21, a limiting block 211 is arranged in the fixed cavity 21, the first pressing block 122 is immersed in the fixed cavity 21, and the slot of the limiting block 211 is engaged with the block of the first pressing block 122 to prevent the first pressing block 122 from shifting in the radial direction, thereby avoiding the failure of the connection between the pressing block 12 and the button 15 when in use. In addition, the first pressing block 122 is fixed to the bracket 2 by a fastener 22, specifically, the fastener 22 can be set to a screw or a pin, etc.

[0029] Preferably, a lock buckle 23 is provided at the bottom of the bracket 2 to facilitate installation of the bracket 2 and expand the scope of use.

[0030] Usage: When the second button 152 located on the circumference of the PCB board 14 needs to be triggered, the edge of the housing 11 or the edge of the display screen 13 in the direction corresponding to a second button 152 is pressed, so that the first pressing block 122 and the connecting block 1211 are subjected to lateral force and elastic deformation is deviated to one side, and the instrument 1 is twisted toward the pressing side as a whole, so that the reverse button 1212 and the bracket 2 are relatively squeezed, and the reverse button 1212 triggers a corresponding second button 152 on the circumference to achieve the corresponding electrical connection of the instrument 1; when the first button 151 located at the center of the PCB board 14 needs to be triggered, only the center of the display screen 13 is pressed or the housing 11 is vertically downward as a whole, so that the first pressing block 122 is subjected to force along the center, and then the first button 151 at the center of the PCB board 14 is triggered to achieve the corresponding electrical connection of the instrument 1. It can be understood that the first pressing block 122 and the second pressing block 121 are both resilient, and the instrument 1 can automatically reset to the original state after the corresponding electrical connection, so as to achieve a multi-directional press control switch.

[0031] The present application provides a combination of a multi-directional instrument + button 15, the purpose of which is to place the button 15 in a hidden space under the display screen 13 to achieve a hidden function. This setting method increases the screen-to-body ratio, has a smaller size, low cost, and has stronger product advantages.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
