DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] A stacked suspended key structure consists of a shell 1, a key 2, an antenna 3, an antenna silicone sleeve 4, and an FPC assembly 5 (a nest / tactile switch). The shell 1 is equipped with the key 2, antenna 3, antenna silicone sleeve 4, and FPC assembly 5. The antenna silicone sleeve wraps the antenna to form an antenna assembly. The antenna assembly is assembled on the shell and is in a suspended state. There is a gap between the antenna silicone sleeve's hanging ear 12 and the shell groove 11. There is also a movable gap between the antenna assembly and the shell, allowing the antenna assembly to move freely, forming a self-adjusting structure. During operation, the force of the key is transmitted to the antenna and the antenna silicone sleeve (i.e., the antenna assembly), and then transmitted to the FPC assembly through the antenna assembly, ultimately triggering the nest / tactile switch.

[0029] There is a gap between the ear of the antenna silicone cover and the groove of the side panel, and there is also a movable gap between the antenna assembly and the shell, forming a suspension structure between the antenna assembly and the shell. This allows the antenna assembly to have sufficient movable gaps between the antenna assembly and the surrounding shell (that is, there are gaps on all six sides of the antenna silicone cover and the shell), while avoiding abnormal noise and key jamming caused by friction, thereby achieving smooth key operation and obtaining a better key feel.

[0030] Specifically, a button mounting position 6, an antenna silicone cover mounting position 7 and an FPC component mounting position 8 are provided on the shell, the button is embedded in the button mounting position, the antenna silicone cover is suspended in the antenna silicone cover mounting position, and the FPC component is bonded to the FPC component mounting position; during operation, when the button is pressed, the button will touch the antenna, the antenna will drive the antenna silicone cover to move, and the protrusion 13 on the antenna silicone cover will touch the FPC component.

[0031] The button mounting position is set at one end of the shell, the antenna silicone sleeve mounting position is set in the middle of the shell, and the FPC component mounting position is set at the other end of the shell; the antenna silicone sleeve mounting position is composed of a spacer 9 and two side panels 10, and the spacer separates the antenna silicone sleeve mounting position from the button mounting position; the two side panels are provided with grooves 11, and the antenna silicone sleeve is provided with ears 12. The ears of the antenna silicone sleeve cooperate with the grooves to make the antenna silicone sleeve in a suspended state and can move freely to form a self-adjusting structure; there is no obstruction between the antenna silicone sleeve mounting position and the FPC component mounting position, and the antenna silicone sleeve can touch the FPC component installed in the FPC component mounting position when it moves.

[0032] The key can be configured as a body 14 and a limiter 15, wherein the body is embedded in the key installation position and the limiter can enhance the feel of the key. The key is configured to be made of silicone material to enhance the feel and elasticity.

[0033] Description of the antenna assembly's self-adjusting structure: When the force of pressing the button is transmitted to the antenna assembly, the antenna assembly can swing. Since the material of the antenna silicone cover is elastic, it can adjust the error caused by assembly and provide a better button feel.

[0034] When the assembly error is small and the tightness is appropriate, the center line of the button and the center line of the antenna silicone cover ear are aligned. At this time, the pressing force of the button is horizontally transmitted to the touch switch, and the button feels good;

[0035] When the assembly is too tight, the antenna assembly tilts. When the button is pressed, the antenna assembly rotates around the center line of the antenna silicone cover ear and is adjusted by the button. This allows the force of the button to be horizontally transmitted to the touch switch, ensuring a good button feel.

[0036] The connection structure between the button and the housing is not a problem to be solved by the present invention. Various existing solutions can be adopted. For example, when implementing the solution, a conventional snap-fit ​​structure can be adopted, or the button can be directly set on the housing by bonding.
