As shown in fig. 1 to 3, a key assembly 100 according to an embodiment of the present utility model includes a PCB 110, an elastic restoring member 120, and a key 130.

As shown in fig. 2, a function key 111 is provided on the PCB board 110.

Among them, the function key 111 is a switching key. Of course, in other embodiments, the function key 111 may be a restart key, a volume adjustment key, a bluetooth key, or the like.

As shown in fig. 1 and 2, the elastic restoring member 120 is disposed on the PCB 110, and the elastic restoring member 120 includes a first elastic arm 121 and a second elastic arm 122 disposed along the width direction of the PCB 110 and spaced apart from the first elastic arm 121.

Specifically, the first elastic arm 121 and the second elastic arm 122 have elasticity, the first elastic arm 121 and the second elastic arm 122 can be deformed after being pressed, and the first elastic arm 121 and the second elastic arm 122 can be restored after the external force disappears.

Referring to fig. 1 and 2, the key 130 includes a pressing portion 131, and a trigger portion 132 connected to the pressing portion 131, where the pressing portion 131 is used to press on the first elastic arm 121 and the second elastic arm 122, and the trigger portion 132 is disposed opposite to the function key 111; the pressing portion 131 is operable to move along the length direction of the PCB 110 to press the first elastic arm 121 and the second elastic arm 122, and cause the triggering portion 132 to trigger the function key 111.

Specifically, when the user presses the pressing portion 131, the pressing portion 131 can move along the length direction of the PCB board 110 and press the first elastic arm 121 and the second elastic arm 122, and when the pressing portion 131 is pressed to move along the length direction of the PCB board 110, the triggering portion 132 also moves along the length direction of the PCB board 110 until abutting against the function key 111 and touching the function key 111. When the user releases the button 130, the pressing portion 131 can be reset under the action of the first elastic arm 121 and the second elastic arm 122.

In the key assembly 100 of the present utility model, when the pressing portion 131 is pressed by a user, the pressing portion 131 drives the first elastic arm 121 and the second elastic arm 122 to deform in the length direction of the PCB 110, so that the first elastic arm 121 and the second elastic arm 122 do not occupy more space in the thickness direction and the width direction of the PCB 110, and after the key assembly 100 is applied to a controller, the key assembly 100 does not occupy more space in the thickness direction and the width direction of the controller under the condition that the thickness direction of the PCB 110 is ensured to be the same as the thickness direction of the controller, and thus the key assembly 100 can be applied to products with smaller width and thickness.

As shown in fig. 2 and 3, in one embodiment, the elastic restoring member 120 further includes a mounting portion 123 disposed on the PCB board 110, a first end of the first elastic arm 121 is connected to the mounting portion 123, a second end of the first elastic arm 121 is spaced from the mounting portion 123 and supports the pressing portion 131, a first end of the second elastic arm 122 is connected to the mounting portion 123, and a second end of the second elastic arm 122 is spaced from the mounting portion 123 and supports the pressing portion 131.

Specifically, the first end of the first elastic arm 121 is integrally formed with the mounting portion 123, the second end of the first elastic arm 121 is suspended and supports the pressing portion 131, the first end of the second elastic arm 122 is integrally formed with the mounting portion 123, and the second end of the second elastic arm 122 is suspended and supports the pressing portion 131. In this way, the second end of the first elastic arm 121 and the second end of the second elastic arm 122 can displace in the length direction of the PCB board 110 when being pressed by the pressing portion 131, and when the user cancels the acting force on the pressing portion 131, the second end of the first elastic arm 121 and the second end of the second elastic arm 122 can reset and drive the pressing portion 131 to reset.

The pressing portion 131 and the first elastic arm 121 are arranged along the length direction of the PCB 110, and the pressing portion 131 and the second elastic arm 122 are arranged along the length direction of the PCB 110. Thus, when the pressing portion 131 receives the pressing force along the length direction of the PCB 110, the pressing portion 131 can drive the first elastic arm 121 and the second elastic arm 122 to deform along the length direction of the PCB 110.

Specifically, the distance between the first elastic arm 121 and the second elastic arm 122 in the width direction of the PCB 110 gradually increases along a preset direction, wherein the preset direction is opposite to the pressing direction of the pressing portion 131.

Wherein, the pressing portion 131 moves along the pressing direction and presses the first elastic arm 121 and the second elastic arm 122 when receiving the pressing force of the user, and by gradually increasing the distance between the first elastic arm 121 and the second elastic arm 122 along the width direction of the PCB board 110 along the preset direction, it can be ensured that the first elastic arm 121 and the second elastic arm 122 provide the resetting force for the pressing portion 131.

Of course, in other embodiments, the distance between the first elastic arm 121 and the second elastic arm 122 in the width direction of the PCB 110 may also gradually decrease along the preset direction.

Specifically, when the pressing portion 131 abuts against the stroke limiting portion 124, the triggering portion 132 abuts against the function key 111 at this time, and can trigger the function key 111, and the triggering portion 132 does not damage the function key 111 at this time. And due to the travel limiting portion 124, the pressing portion 131 is further pressed, so that the triggering portion 132 further presses the function key 111 to damage the function key 111 can be prevented.

When the key 130 is in the initial state, the stroke limiting part 124 is located at the front of the pressing part 131 along the pressing direction of the pressing part 131, and the pressing part 131 is spaced from the stroke limiting part 124, when the key 130 is pressed, the pressing part 131 can move along the pressing direction until abutting against the stroke limiting part 124, at this time, the triggering part 132 abuts against the function key 111 and can trigger the function key 111, but due to the existence of the stroke limiting part 124, the triggering part 132 can be prevented from further pressing the function key 111 to cause the destruction of the function key 111 due to the fact that the pressing part 131 is further pressed.

Specifically, in the present embodiment, the pressing portion 131 is provided on the mounting portion 123, and the pressing portion 131 and the mounting portion 123 are of an integrally molded structure.
