Most screen projectors are connected with a computer through a network, and the network, the reset, the flashing and other operations of the screen projectors are completed through keys which are indispensable functional parts.

In the related prior art, the key pressing mode mainly includes a mode that a normal structure of a touch key is matched with a touch pad, a mechanical key, a universal elastic arm or a single particle has no elastic arm. The touch key mode has high cost and is generally less adopted; the button without the elastic arm is easy to shake, the shaking also makes a sound, and the button is not suitable for being used on the side.

The common key structure with elastic arms is generally: the pressing piece 200 (key cap) is exposed out of the shell, when external force acts on the key, the key contact presses an electronic switch on the PCB to activate corresponding functions, then the pressing piece 200 is connected by the elastic arm and rebounds and resets after being loosened, and the pressing function and the complete functional action of rebounding and resetting after the key is loosened are completed. Under normal conditions, the touch of the key can be influenced by the length, the thickness and the angle of actuating force and reaction force of the elastic arm, the touch of the key is hard when the elastic arm is short, and the touch of the key pressing force which is not parallel to the handle of the electronic switch is also influenced. For the screen projection key, a key with an elastic arm is commonly used; however, since the screen projector itself is a small product, the design and installation of the elastic arm is limited by the inner space, which affects the pressing feeling.

The utility model aims at providing a switch button structure, it includes elastic arm 100. The elastic arm 100 can ensure the hand feeling of the key after being installed in a relatively small space. The switch button structure is used for an electronic device 1 such as a screen projector. The electronic apparatus 1 includes a housing 300.

Referring to fig. 1 and 2, the switch key structure includes a pressing member 200, a positioning member 400, and a resilient arm 100.

The pressing piece 200, i.e., the electronic switch that is pressed by the user so that the pressing piece 200 can touch the electronic device, activates the corresponding function.

And the positioning piece 400 is fixedly connected with the housing 300.

And the two ends of the elastic arm 100 are respectively connected with the pressing piece 200 and the positioning piece 400. When the pressing member 200 is pressed, the elastic arm 100 is elastically deformed by the restraint of the positioning member 400; based on the elastic deformation and the rebound of the elastic arm 100, an activation function and a reset function of the press 200 to the electronic switch are respectively performed.

As shown in fig. 3 and 4, the elastic arm 100 includes at least two extension sections connected to each other, the at least two extension sections both extending in a pressing direction of the pressing piece 200, and the at least two extension sections extending in a direction perpendicular to the pressing direction.

It should be noted that the housing 300 is configured with receiving holes for circumferentially and radially limiting the pressing elements. The axial direction of the receiving hole is a pressing direction of the pressing member 100, i.e., a moving direction of the pressing member 100 when pressed.

Further, it should be noted that the at least two extending sections are formed by extending in two directions, one of which is an axial direction of the receiving hole and the other is a perpendicular direction of the axial direction (in a preferred embodiment, but not limited thereto, if a cross section of the housing 300 is a circular cross section, the two directions are two mutually perpendicular radial directions of the circular cross section, and if a cross section of the housing 300 is an elliptical cross section, the two directions are a major axis direction and a minor axis direction of the elliptical cross section).

Optionally, referring to fig. 6, the plane defined by the at least two extension sections is parallel to the pressing direction. Namely: the elastic arm 100 is kept parallel to the axis of the pressing member 200 during the elastic deformation process, and at this time, the reaction force applied to the user is along the pressing direction and is small, so that the user feels comfortable and light.

Optionally, the at least two extension segments comprise a first resilient segment 100 a; the elastic arm 100 includes a first connection portion 100d, the first connection portion 100d extends from the pressing piece 200 to the first elastic section 100a in a vertical direction of the plane, and both ends of the first connection portion 100d are connected to the pressing piece 200 and the first connection portion 100d, respectively. In a specific implementation process, since the pressing piece 200 needs to touch the electronic switch 500a on the circuit board 500, the mounting positions of the pressing piece 200 and the first elastic section 100a in the housing have a height difference, as shown in fig. 6. For this purpose, in order to transition the pressing member 200 and the first elastic segment 100a through the first connection portion 100d, the first connection portion 100d further extends from the pressing member 200 to the first elastic segment 100a in a direction perpendicular to the plane. Further, as described with reference to fig. 6, the first connection portion 100d is not linear, but is curved, that is: the first connection portion 100 extends in the pressing direction while extending in the perpendicular direction to the plane.
