The breath light, which is a device that lights alternate between light and dark under the control of a microcomputer, is usually installed in an electronic device to remind a user to receive a message. In the related art, when the breathing lamp is installed in the electronic device, the breathing lamp is mainly installed by opening a hole on a screen of the electronic device. However, this arrangement may occupy the space of the electronic device, and may affect the screen occupation ratio of the electronic device.

In order to solve the above problems, the following two methods can be adopted in the related art:

firstly, the setting of the breathing lamp is cancelled, and then screen-off display or bright screen display is adopted, namely, the time and patterns are displayed on the screen through the chip control. However, this method not only increases the power consumption of the electronic device, but also requires long-time use of screen pixels for display, which is likely to leave afterimages on the screen and affect the use of the screen.

And secondly, combining the breathing lamp with the keys, so that the breathing lamp is arranged on the non-display side of the electronic equipment. Specifically, the button passes through movable support and casing swing joint, and the periphery that is located movable support is provided with a plurality of fixed connection in the illuminating part of casing, and the illuminating part can send light in order to illuminate the button towards the button to reach the purpose of reminding the user. However, in this way, there is a relative movement between the key and the light emitting element, so as to avoid collision between the key and the light emitting element during the movement of the key, a large distance needs to be left between the key and the light emitting element, which is not favorable for realizing the miniaturization design of the key structure.

Based on this, the embodiment of the utility model provides a key structure and electronic equipment, wherein the breathing lamp and the keys of the electronic equipment are combined and arranged on the non-display side of the electronic equipment together, so that the influence on the screen occupation ratio of the electronic equipment is avoided. And the breathing lamp is arranged in the key structure, rather than being arranged on the shell of the electronic equipment separately, so that the space in the key structure is fully utilized, and the miniaturization design of the key structure is favorably realized. In addition, the key structure provided by the embodiment of the utility model is also provided with the optical diffusion element, and the light emitted by the light-emitting piece can be uniformly diffused to the light-transmitting key through the optical diffusion element positioned between the light-emitting piece and the light-transmitting key, so that the number of the light-emitting pieces is reduced, and the power consumption of the electronic equipment is further reduced.

Specifically, the key structure includes a pressing bracket 1, an electric connection member 2, a light emitting member 3, an optical diffusion member 4, and a light-transmissive key 5. The electric connection piece 2 is arranged on the pressing bracket 1. The luminous piece 3 is arranged on one side of the electric piece 2 departing from the pressing bracket 1 and is electrically connected with the electric piece 2. The optical diffusion element 4 is arranged on the electric connecting piece 2 and is positioned on the light emitting side of the light emitting piece 3, and the optical diffusion element 4 is used for diffusing the light emitted by the light emitting piece 3. The light-transmitting button 5 is connected to the side of the optical diffuser element 4 facing away from the luminous element 3.

That is, the pressing bracket 1, the electric connection member 2, the light emitting member 3, the optical diffusion member 4, and the light-transmissive key 5 are sequentially disposed in a certain direction. Wherein, the illuminating part 3 can be a light emitting diode or a bulb, and the illuminating part 3 can be connected with the circuit board of the electronic device through the electric connecting part 2 electrically connected with the illuminating part, the circuit board of the electronic device controls the illuminating part 3 to emit light towards the optical diffusion element 4 according to the preset frequency, the light is diffused by the optical diffusion element 4 and then irradiates the light-transmitting key 5, and the alternating light and shade effect can be created, so that a user can conveniently judge whether the electronic device receives a new message or not according to the light on the light-transmitting key 5, or whether the electronic device needs to be charged or not.

The predetermined component may be a housing of the electronic device, and the key structure may be fixed to the housing of the electronic device through the connecting portion 12 when the key structure is installed on the electronic device, for example, two protruding blocks may be disposed at an interval on one side of the housing of the electronic device, and the connecting portion 12 may be a non-closed buckle-like structure, and the connecting portion may be connected to the protruding blocks in a snap-fit manner, so as to fix the pressing bracket 1 to the housing of the electronic device.

Furthermore, the pressing portion 11 is provided with an electrical contact 13, and the pressing portion 11 is used for driving the electrical contact 13 to move relative to the connecting portion 12 when receiving a pressing force. The pressing portion 11 can be forced to move relative to the connecting portion 12 to drive the electrical contact 13 to contact another electrical contact disposed on the housing of the electronic device to achieve electrical conduction, so that the circuit board of the electronic device receives a pressing signal to perform a related operation. It is understood that, in other embodiments, instead of providing the electrical contact 13 on the housing of the electronic device, the pressing portion 11 may be forced to press the micro switch between the housing of the electronic device and the pressing portion 11, so that the circuit board of the electronic device receives the pressing signal to perform the related preset operation.

Furthermore, the pressing portion 11 can be made of an elastic material, such as silicone or soft PVC, so that when the user presses the transparent key 5, the pressing portion 11 can be elastically deformed by being stressed, and thus moves toward the housing of the electronic device to drive the electrical contact 13 to move to another electrical contact disposed on the housing of the electronic device to be electrically connected to conduct. When the pressing action is removed, the pressing portion 11 can move away from the electronic device to return to the initial state by its own elasticity.

Specifically, the size of the first through hole 611 is at least larger than the light emitting area of the light emitting element 3, and is adjusted according to the positions of the supporting element 6 and the light emitting element 3, so as to prevent the light emitted by the light emitting element 3 from being blocked by the supporting element 6.

The support member 6 is arranged between the electric connecting member 2 and the optical diffusion element 4 to support the optical diffusion element 4, so that the structural strength of the key structure can be improved. At the same time, the distance between the optical diffusion element 4 and the luminous element 3 is adjusted by the support 6, so that the luminous element 3 can be adapted to different optical diffusion elements 4.

Further, since the first through hole 611 is formed in the supporting member 6, and the first through hole 611 is formed corresponding to the light emitting member 3, the light emitting member 3 can at least partially extend into the first through hole 611, that is, the supporting member 6 surrounds the light emitting member 3 to shield the light emitting member 3, so as to prevent the light emitting member 3 from being exposed and damaged. It is understood that the supporting member 6 may be made of a non-light-transmitting material, so that when the light-emitting member 3 extends into the first through hole 611, the supporting member 6 can block light from being emitted from the position of the non-light-transmitting key 5, so as not to affect the appearance of the electronic device.

In some embodiments, the supporting element 6 includes a first part 61 and a second part 62, the first part 61 is disposed on a side of the electric component 2 facing away from the pressing bracket 1, the first part 61 is provided with a first through hole 611 and a first installation cavity 612, the first installation cavity 612 is located on a side of the first part 61 facing away from the electric component 2, the first installation cavity 612 is communicated with the first through hole 611, the second part 62 is disposed in the first installation cavity 612, the second part 62 is provided with a second through hole 621 corresponding to the first through hole 611, the second through hole 621 is communicated with the first through hole 611, the optical diffusion element 4 is disposed on the second part 62, and the light-transmissive key 5 is connected to the first part 61. Specifically, when the light-transmitting key 5 is connected to the first member 61, the opening of the first installation cavity 612 of the first member 61 is mainly covered, so that the second member 62 is located inside the first member 61 (i.e. located in the first installation cavity 612), and the optical diffusion element 4 is disposed in the second member 62, i.e. the light-transmitting key 5 can dispose the second member 62 and the optical diffusion element 4 between the light-transmitting key 5 and the first member 61, so that the overall structure of the key structure can be more compact, and the miniaturization design of the key structure can be realized.

Specifically, the mounting surface 41 may be a tapered surface, and the second mounting cavity 622 may be a tapered cavity, and the width of the second mounting cavity 622 gradually decreases from the second side 624 to the first side 623. That is, the mounting surface 41 may be provided as a tapered surface corresponding thereto, and is formed extending from the outer periphery of the diffusing surface 42 toward the side of the optical diffusing element 4 away from the diffusing surface 42, so that the tapered surface can completely abut against the surface corresponding to the tapered cavity to fix the optical diffusing element 4 in the second mounting cavity 622.
