The first end of the key assembly penetrates into the key hole, the second end is exposed outside the shell, the limiting steel sheet is assembled on the shell, and the key assembly is limited through the limiting steel sheet. Therefore, the matching relation between the key assembly and the key hole, the matching relation between the limiting steel sheet and the key assembly and the matching relation between the limiting steel sheet and the shell need to be considered during design and assembly, the number of the related matching relations is large, and the key assembly is inconvenient to assemble on the shell.

Based on the above defects, embodiments of the present disclosure provide an electronic device, which is described in detail below with reference to the accompanying drawings:

in embodiments of the present disclosure, electronic devices include, but are not limited to: the intelligent mobile phone comprises a mobile phone, a tablet computer, an iPad, a digital broadcast terminal, a messaging device, a game console, a medical device, a fitness device, a personal digital assistant, an intelligent wearable device, an intelligent television, a sweeping robot, an intelligent sound box and the like.

Referring to fig. 1, the electronic device includes: a housing 110 and a key assembly 120.

Referring to fig. 2, the case 110 is provided with a key hole 111 communicating an inner wall 112 and an outer wall 113 of the case 110. Illustratively, the housing 110 includes a middle frame, and the key hole 111 is provided at a side surface of the middle frame. The display panel is arranged on the front side of the middle frame, the rear shell is arranged on the back side of the middle frame, the electronic equipment can be formed in a packaged mode, and the components are arranged in the accommodating cavity formed by the middle frame, the display panel and the rear shell.

Referring to fig. 2 and 3 in combination, key assembly 120 includes: the key assembly comprises a key body 121 and a limiting member 122, wherein the key body 121 includes a first end 102 and a second end 103 opposite to the first end 102, the limiting member 122 is rotatably disposed at the first end 102, the first end 102 and the limiting member 122 of the key body 121 penetrate through the key hole 111 from outside to inside, and the limiting member 122 is limited in the casing 110. Thus, the key assembly 120 is limited in the key hole 111 by the limiting member 122.

Illustratively, the second end 103 of the key body 121 protrudes outward beyond the outer wall 113 of the housing 110. Illustratively, the second end 103 of the key body 121 is recessed inwardly in the key hole 111. It is understood that the user may touch and press the key body 121.

Illustratively, the key assembly 120 includes a volume key assembly and a switch key assembly.

Fig. 4 is a schematic structural diagram of a key assembly 120 according to an exemplary embodiment of the disclosure in a first state, fig. 5 is a schematic structural diagram of the key assembly 120 according to an exemplary embodiment of the disclosure before being assembled with a housing 110, and fig. 6 is a schematic structural diagram of the key assembly 120 according to an exemplary embodiment of the disclosure in a second state. How key assembly 120 and housing 110 are assembled is described below in conjunction with the following figures:

before key assembly 120 and housing 110 are assembled, referring to fig. 4, limiting member 122 is rotated to minimize the dimension of key assembly 120 in the axial direction (x-axis direction) perpendicular to key hole 111, so that key assembly 120 can easily pass through key hole 111 from outside to inside to reach the state shown in fig. 5. The axial direction of the key hole 111 may be the y-axis direction.

After the key assembly 120 passes through the key hole 111, the limiting member 122 can be shifted by the shift lever to rotate and limit the key assembly 120 in the housing 110, for example, referring to fig. 6, the limiting member 122 is rotated to maximize the size of the key assembly 120 along the x-axis direction, so as to limit the key assembly 120 in the key hole 111, referring to fig. 3.

Based on the above, before the key assembly 120 and the casing 110 are assembled, the control stopper 122 is rotated, so that the size of the key assembly 120 in the axial direction perpendicular to the key hole 111 is small, and the key assembly 120 can easily penetrate into the key hole 111 from the outside to the inside. Then, the limiting member 122 is controlled to rotate, so that the limiting member 122 is limited in the casing 110, and the key assembly 120 is assembled to the casing 110. By using the key assembly 120 with the structure, compared with the situation that the key assembly 120 is limited by the limiting steel sheet, the matching relation between the key assembly 120 and the shell 110 is simplified, and the key assembly 120 is convenient to assemble on the shell 110.

In addition, the key assembly 120 has a simple structure, and the key assembly 120 and the casing 110 are simply matched, so that the pressing operation of the key assembly 120 is prevented from being influenced by a limiting steel sheet and the like, and the working reliability of the key assembly 120 is ensured.

In some embodiments, with continued reference to fig. 2, a surface of the limiting member 122 facing the first end 102 (which may be referred to as the first surface 101) abuts against the inner wall 112 of the housing 110. Thus, when the limiting member 122 is rotated to the inner wall 112 of the casing 110, one surface of the limiting member 122 facing the first end 102 abuts against the inner wall 112 of the casing 110, so as to limit the key assembly 120 in the key hole 111. Illustratively, the first face 101 may be parallel to the inner wall 112 of the housing 110. Thus, rotation of the limiting member 122 is facilitated. For example, the first surface 101 is provided with a protrusion, the inner wall 112 of the housing 110 is provided with a groove, and after the limiting member 122 rotates, the protrusion is limited in the groove, so that the limiting member 122 is limited in the housing 110.

In addition, the other surfaces of the limiting member 122 besides the first surface 101 may also be limited to the housing 110, which is not specifically limited in this disclosure.

In some embodiments, referring to fig. 4 and 6 in combination, the retaining member 122 extends in an axial direction perpendicular to the key hole 111. For example, the limiting member 122 extends along the x-axis direction, so that the limiting member 122 forms an elongated structure, and after the limiting member 122 rotates, more parts of the limiting member 122 are limited in the housing 110. For the example that the first surface 101 of the limiting member 122 abuts against the inner wall 112 of the casing 110, after the limiting member 122 rotates, the area of the first surface 101 of the limiting member 122 abutting against the inner wall 112 of the casing 110 is large, which is beneficial to stably assemble the key assembly 120 to the casing 110 by the limiting member 122.

In addition, the limiting members 122 may also extend in two, three, or four directions perpendicular to the axial direction of the key hole 111, and may have a limiting effect. For example, the position-limiting member 122 may also be a block structure, or other regular or irregular structures, which are not specifically limited by the present disclosure.

In some embodiments, referring to fig. 4 and 6 in combination, the end of the retaining member 122 is provided with a chamfered or rounded configuration. In this way, the limiting member 122 can be prevented from scratching components arranged around the limiting member when rotating. When the limiting member 122 extends along the x-axis direction, an end of the limiting member 122 along the x-axis direction is set to be a chamfered structure or a rounded structure.

Fig. 7 is an exploded schematic view of a key assembly 120 shown in accordance with an exemplary embodiment of the present disclosure. In some embodiments, referring to fig. 7, the first end 102 of the key body 121 is provided with a limiting hole 123, and the key assembly 120 further includes a limiting post 124 disposed in the limiting hole 123; the limiting member 122 has a rotation hole 125, and the rotation hole 125 is rotatably sleeved on the limiting post 124. The limiting member 122 rotates under the action of an external force, and when there is no external force, the relative positional relationship between the limiting member 122 and the limiting post 124 is not changed. The limiting member 122 is rotatably disposed on the key body 121 by matching the limiting post 124 with the limiting member 122.

Further, in some embodiments, the limiting post 124 is fixed to the limiting hole 123, and the rotation hole 125 is in threaded connection with the limiting post 124. Thus, after the toggle limiting member 122 rotates, the relative position relationship between the limiting member 122 and the limiting column 124 is limited by the screw thread and is not easy to change, and the rotation angle of the limiting member 122 can be accurately controlled by the screw thread connection relationship. Illustratively, the inner wall 112 of the rotation hole 125 is provided with an internal thread, and the outer wall 113 of the restraining post 124 is provided with an external thread.

Further, in some embodiments, when the limiting member 122 is a disc-shaped structure, the rotating hole 125 is eccentrically disposed on the limiting member 122, so as to be limited on the inner wall 112 of the housing 110 after the limiting member 122 rotates.

In some embodiments, with continued reference to fig. 2, the key body 121 includes a first portion 127 and a second portion 128 connected to the first portion 127; the end of the first portion 127 opposite to the second portion 128 is a first end 102, and the end of the second portion 128 opposite to the first portion 127 is a second end 103; the first portion 127 has a smaller dimension than the second portion 128 in an axial direction (in the x-axis direction) perpendicular to the key hole 111. Thus, the first portion 127 of the key body 121 can easily pass through the key hole 111 from the outside to the inside.

In some embodiments, with continued reference to fig. 2, the key hole 111 includes a first hole 114 and a second hole 115 in communication with the first hole 114, the first hole 114 having a radial dimension that is smaller than a radial dimension of the second hole 115, the first hole 114 mating with the first portion 127, the second hole 115 mating with the second portion 128. It should be noted that the "radial dimension" of the first hole 114 and the second hole 115 refers to the dimension along the x-axis direction. Thus, the components in the housing 110 can be shielded by the inner wall 112 of the first hole 114, and the components in the housing 110 can be prevented from being observed through the second hole 115, so as to ensure the appearance of the electronic device.

In some embodiments, referring to fig. 3 and 5 in combination, the electronic device further includes a circuit board 130 disposed in the housing 110, the circuit board 130 is provided with an elastic switch 131, and the elastic switch 131 is pressed to trigger an electrical signal, which includes a volume adjustment signal, a power-on signal or a power-off signal. Illustratively, the circuit board 130 is a flexible circuit board 130 to fit irregular spaces within the housing 110. The key assembly 120 further includes an elastic key body 126 disposed at the first end 102, and the elastic key body 126 contacts the elastic switch 131. The key body 121 is movable a slight distance in the y-axis direction, and the key body 121 is stably assembled to the housing 110 by the elastic switch 131 and the stopper 122. Specifically, when the key body 121 is pressed from the outside to the inside (i.e. along the y-axis direction), the key body 121 drives the elastic key body 126 to press the elastic switch 131, and the elastic switch 131 triggers the corresponding electrical signal. When the key body 121 stops being pressed, the elastic switch 131 bounces the elastic key body 126 along the opposite direction of the y-axis, and the elastic key body 126 drives the key body 121 to make the limiting member 122 abut against the inner wall 112 of the housing 110.

Illustratively, the material of the elastic key body 126 includes rubber, which gives elasticity to it without damaging the elastic switch 131, and also increases the user's pressing experience.

In some embodiments, the number of the position-limiting members 122 is at least two, and the position-limiting members are disposed around the elastic key body 126 in a distributed manner. In this way, at least two position-limiting members 122 located around the elastic key body 126 cooperate to limit, so that the key assembly 120 is stably assembled to the casing 110 after the elastic switch 131 bounces off the elastic key body 126.

Illustratively, the number of the limiting members 122 is two, and the two limiting members are oppositely disposed on two sides of the elastic key body 126.

The above embodiments of the present disclosure may be complementary to each other without conflict.

The above description is only exemplary of the present disclosure and should not be taken as limiting the disclosure, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure.
