In the field of intelligent home, the appearance of intelligent electronic products is gradually changed into structures such as spherical, cylindrical and profiling from the square of basis gradually, and the key size is long due to the special-shaped structures, so that certain use defects exist. For example, in order to match the appearance of an electronic product, a long key is required to be matched, and the long key is easy to shake and generate jolt, but if the key is wrapped by soft rubber to avoid shake of the key, poor positioning precision is introduced, so that the key is deformed to cause key clamping, and user experience is affected.

In order to solve the above problems, the present utility model provides the following technical solutions, and the following technical solutions of the present utility model are further described by specific embodiments with reference to the accompanying drawings.

Referring to fig. 1 to 3 in combination, the embodiment of the present utility model provides a key assembly, which is configured to be installed in a preset installation portion 30 on an electronic device, wherein a PCBA board matched with the key assembly is disposed in the electronic device, and a switch is disposed on the PCBA board, and when a key body 10 in the key assembly is pressed, the switch on the PCBA board can be acted on, so that the electronic device executes a corresponding function.

In this embodiment, the key assembly includes a base 20, the base 20 is provided with an opening for accommodating the key body 10, and the key body 10 is slidably disposed in the opening; the base 20 is provided with a surrounding wall 22 which can deform under force along the hole edge of the hole, and the surrounding wall 22 surrounds the periphery of the key body 10.

The surrounding wall 22 has a strip-shaped structure, and the surrounding wall 22 extends along the pressing direction of the key body 10.

It will be appreciated that the cylindrical flexible glue of conventional design surrounding the wall 22 tends to cause high side wall friction and thus a snap problem. In this embodiment, the surrounding wall 22 with a strip-shaped structure and being deformable not only can support the key body 10 to avoid shaking the key body 10, thereby avoiding the problem of vibration caused by shaking, but also can deform according to the pressing action of the key body 10 to avoid the surrounding wall 22 from forming a barrier on the movement path of the key body 10, thereby preventing the surrounding wall 22 from interfering with the movement of the key body 10 and further overcoming the problem of blocking keys.

Further, the key assembly is embedded in the mounting portion 30 of the electronic device, and the mounting portion 30 forms an embedded wall 31 around the position of the key assembly.

It will be appreciated that, in general, the key assembly is embedded in the housing of the electronic device, and the housing is typically a rigid plastic structure.

In this embodiment, the surrounding wall 22 is a soft plastic structure to achieve the deformable effect.

In addition, the gap width between the key body 10 and the embedded wall 31 is smaller than the gap width between the key body 10 and the surrounding wall 22, so that the electronic device can avoid abnormal key sounds caused by collision between the key body 10 and the mounting part 30 (the housing) in an operating state where vibration is generated (for example, when audio is played).

Further, the insertion wall 31 is provided with a step 311, and the pressing stroke of the key body 10 is smaller than the depth of the step 311. It will be appreciated that the depth of the step 311 is the distance between the step surface of the step 311 and the outer surface of the mounting portion 30. In this way, the problem of the key being stuck due to interference with the mounting portion 30 during the pressing of the key body 10 can be avoided.

Specifically, the key body 10 includes a key core 12 and a key cap 11 sleeved on the top of the key core 12, and the key cap 11 is provided with a light emitting hole 16; the key core 12 comprises a light guide filling member and a shading filling member, the position of the light guide filling member corresponds to that of the light outlet hole 16, light on the PCBA board can be emitted outwards through the light guide filling member and the light outlet hole 16, and the light outlet hole 16 can be set into different shapes so as to prompt the corresponding function of the key body 10. The shading filling piece is used for shading so that the luminous shape on the keycap 11 is more accurate.

In this embodiment, the bottom of the key core 12 is provided with the first reinforcing ribs 14, the first reinforcing ribs 14 are cross-shaped, and the positions of the first reinforcing ribs 14 correspond to the positions of the light shielding filling members.

In this embodiment, the first reinforcing rib 14 can be deformed by force. Because the first reinforcing rib 14 is cross-shaped, and comprises two longitudinal linear structures and two transverse linear structures, compared with the common planar reinforcing structure, the linear reinforcing structure can be more attached to the deformation of the key body 10, the strength of the bottom surface is increased, the connection tightness between the first reinforcing rib and the key body 10 is improved, the purpose of shading light is further achieved, and the light leakage of the light on the PCBA is avoided, so that the deformation of the luminous shape on the key cap 11 is caused.

Further, the bottom of the key core 12 is further provided with a second reinforcing rib 15, the second reinforcing rib 15 is of an annular structure, and the second reinforcing rib 15 is wound around the bottom of the key core 12. The second reinforcing ribs 15 can further provide a linear reinforcing structure, thereby further increasing the bottom strength and the light shielding strength of the key body 10.

In this embodiment, the base 20 includes a bottom plate 21, the openings are formed on the bottom plate 21, and the positions of the bottom plate 21 outside the openings are provided with warp and weft reinforced frames capable of being deformed by force.

It can be appreciated that the warp and weft reinforcement skeleton is formed by a plurality of transverse rib structures and a plurality of longitudinal rib structures in a staggered arrangement, and can cooperate with the appearance of the electronic device while providing a stable supporting function for the key body 10, so as to improve the connection tightness with the mounting portion 30, thereby further avoiding the shaking of the key body 10.

In addition, air pressure is generated when the key body 10 is pressed, and the conventional open air hole design has poor circulation effect on air pressure and is easy to cause light leakage. In the present embodiment, an air pressure groove 23 is disposed between two adjacent openings on the base 20, and the air pressure groove 23 can enable each key body 10 to pass through to achieve the purpose of balancing air pressure, and since the air pressure groove 23 is disposed between the adjacent key bodies 10, but not on the key bodies 10, no light leakage occurs.

In this embodiment, the bottom of the key body 10 is provided with a contact 13 for contacting with a switch on the PCBA board, and the surface of the contact 13 is covered with a deformable buffer member 131. It can be understood that the buffer member 131 is of a soft plastic structure, and the buffer member 131 is coated on the contact 13, so that the idle stroke of the key body 10 can be reduced in the process of pressing the contact 13 to be in contact with the switch on the PCBA, the resistance when the key body 10 is pressed is increased, the pressing feel of the key body 10 can be improved, and in addition, the abrasion and noise problems caused by the direct contact of the hard contact 13 with the switch can be avoided.

Based on the foregoing embodiments, an embodiment of the present utility model further provides an electronic device, including a key assembly as any one of the above.

The above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
