Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a key assembly and an electronic device. Background Art

[0002] Electronic devices are usually equipped with buttons for adjusting volume or controlling power switches. When a user needs to execute the function corresponding to a button, the corresponding function can be realized by pressing the button to trigger the button switch. When a user uses a clamp to clamp an electronic device, such as a mobile phone holder to clamp a mobile phone, functions such as live broadcasting, self-timer, and video watching can be realized.

[0003] In the related art, the key is configured to be movable in the length direction so that the key can be misaligned with the key switch, thereby preventing the clamp from accidentally touching the key. However, regardless of whether the key is misaligned with the key switch, the outer side of the key will always protrude from the outer side wall of the middle frame, and the clamp will still clamp the key. The key is easily damaged by the squeezing of the clamp, which shortens the service life of the key. Utility Model Content

DETAILED DESCRIPTION

[0055] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0057] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0058] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an embodiment of the present application provides a key assembly, and the key assembly includes a carrier 100 and a key 200. It should be noted that the key assembly provided in the embodiment of the present application can be installed in electronic devices such as mobile phones and computers. The carrier 100 can be, for example, a middle frame in an electronic device. The carrier 100 can include a metal part 140 and a plastic part 150, and the metal part 140 and the plastic part can be an integral structure of injection molding.

[0059] The carrier 100 is provided with a groove 110, and the groove 110 is provided with a through hole 130 penetrating the outer surface 120 of the carrier 100. It is understood that the outer surface 120 of the carrier 100 refers to the surface touched by the user, such as the surface touched when holding by hand or clamping with a clamp.

[0060] The button 200 penetrates into the groove 110 through the through hole 130, and the button 200 can slide between a first position and a second position in the groove 110. When the button 200 slides from the first position to the second position, the pressed surface of the button 200 does not protrude from the outer surface 120, and the button 200 can be hidden in the carrier 100.

[0061] With such a configuration, when the outer side of the carrier needs to be clamped and the user does not want to trigger the button, the button can be moved to the second position to avoid accidentally touching the button and prevent the button from being damaged by the clamping member, thereby extending the service life of the button, that is, extending the service life of the button assembly.

[0062] The following is combined with Figures 1 to 6 The various components and functions of the key assembly provided in the embodiment of the present application are described in more detail.

[0063] like Figure 1 As shown, in some embodiments, the groove 110 includes a first groove wall 111 and a second groove wall 112 that are arranged opposite to each other, and the first groove wall 111 is provided with a through hole 130. It should be noted that the distance between the first groove wall 111 and the outer surface 120 of the carrier 100 is smaller than the distance between the second groove wall 112 and the outer surface 120. That is, if the key assembly is installed in an electronic device, the first groove wall 111 is the groove wall on the outside of the electronic device, and the second groove wall 112 is the groove wall on the inside of the electronic device.

[0064] The key assembly further includes an elastic assembly 400, which is connected to the second groove wall 112 and extends toward the key 200. When the key 200 moves to the second position, the elastic assembly 400 abuts against the key 200, and one end of the key 200 is respectively squeezed by the elastic assembly 400 and the first groove wall 111. Since both sides of one end of the key 200 are respectively squeezed by the elastic assembly 400 and the first groove wall 111, the key 200 can be stably confined at the second position.

[0065] Combination Figure 1 , Figure 4 and Figure 5As shown, in some embodiments, the elastic component 400 includes a positioning member 410 and a supporting member 420, and the supporting member 420 is elastic. One end of the positioning member 410 is connected to the second groove wall 112, and the other end extends toward the key 200 and is connected to the supporting member 420. The side of the supporting member 420 that is away from the positioning member 410 abuts against one end of the key 200. It should be noted that when the key 200 is pressed and moves toward the second groove wall 112, the key 200 will abut against the side of the supporting member 420 that is toward the first groove wall 111, so that the supporting member 420 will be elastically deformed, generating a squeezing force on the key 200.

[0066] Combination Figure 4 , Figure 5 and 6 As shown, in some embodiments, the support member 420 includes a first support portion 421, a second support portion 422 and a third support portion 423 connected in sequence. The first support portion 421 and the third support portion 423 are respectively located on both sides of the positioning member 410. The second support portion 422 engages with the positioning member 410 on the side facing the positioning member 410, and the second support portion 422 abuts against one end of the button 200 on the side facing away from the positioning member 410. It should be noted that the support member 420 can be made of silicone material and has elasticity. The first support portion 421 and the third support portion 423 are symmetrically distributed on both sides of the second support portion 422, so that the support portion 420 can be evenly stressed. The end surface of the positioning member 410 is provided with a first clamping structure 411, and the surface of the second support portion 422 facing away from the first groove wall 111 is provided with a second clamping structure 424, and the first clamping structure 411 is clamped with the second clamping structure 424. It should be noted that, either one of the first clamping structure 411 and the second clamping structure 424 may be a protrusion, and the other may be a groove. Figure 6 The figure shows a situation where a protrusion is provided on the end surface of the positioning member 410, and a groove is provided on the surface of the second support portion 422 away from the first groove wall 111. With such a configuration, the limiting member and the second groove wall 112 can be assembled together more flexibly and conveniently.

[0067] Combination Figure 2 and Figure 4 As shown, in some embodiments, the first groove wall 111 includes a first section 113 and a second section 114 connected in the sliding direction of the key 200 , the first section 113 is provided with a through hole 130 , and the second section 114 gradually moves away from the outer surface 120 relative to the first section 113 .

[0068] The button 200 has a first protrusion 210 on one side facing the second groove wall 112, and the first protrusion 210 includes a first abutting portion 211. When the button 200 slides from the first position to the second position, the first abutting portion 211 slides from abutting against the first section 113 to abutting against the second section 114. It can be understood that the first abutting portion 211 can limit the button 200 to prevent the button 200 from being separated from the groove 110, that is, to prevent the button 200 from being separated from the carrier 100. At the same time, during the movement of the button 200, the second section 114 guides the button 200, so that the button 200 can move along the length direction and move toward the second groove wall 112, so that when the button 200 reaches the second position, it can be hidden in the carrier 100 to avoid accidentally touching the button 200.

[0069] Figure 4 FIG. 4 is a schematic diagram showing the elastic component 400 in an initial state. Figure 5 The diagram shows the elastic member 400 in the first deformation state. When the button 200 moves to the second position, the first protrusion 210 squeezes the end face of the elastic component 400, and the side of the elastic component 400 close to the second section 114 is squeezed by the first protrusion 210 and deformed to the first deformation state. At this time, the end face of the second support portion 422 toward the first groove wall 111 is inclined, and the two sides of the first protrusion 210 are respectively subjected to the squeezing force applied by the second section 114 and the elastic component 400. At this time, the button 200 can be stably restricted in the second position to ensure that the button 200 can remain hidden in the carrier 100. In this way, since the clamp or the user's hand cannot press or touch the button 200 in the second position, it can meet the user's needs to avoid accidentally touching the button 200 in live broadcasts, selfies, etc.

[0070] like Figure 3 As shown, in some embodiments, the first protrusion 210 includes a protruding portion 212 and at least one first abutting portion 211. At least one side of the protruding portion 212 in a direction perpendicular to the groove bottom 115 of the groove 110 is connected to the corresponding first abutting portion 211, the first abutting portion 211 extends toward the groove bottom 115 of the groove 110 or toward the groove top 116 of the groove 110, and the side of the first abutting portion 211 facing away from the second groove wall 112 abuts against the first groove wall 111. Figure 3 The figure is a schematic diagram of a structure with two first abutting portions 211 . With such a configuration, the first abutting portions 211 on both sides can be restricted in the groove 110 to prevent the button 200 from being separated from the carrier 100 .

[0071] Combination Figure 1 and Figure 5As shown, in some embodiments, the key assembly further includes a switch member 300, and the switch member 300 is mounted on the groove wall of the groove 110 opposite to the through hole 130. The button 200 also has a second protrusion 220 on the side facing the second groove wall 112. When the button 200 is in the first position, the button 200 can be pressed so that the second protrusion 220 triggers the switch member 300. When the button 200 is in the second position, the second protrusion 220 cannot trigger the switch member 300. It should be noted that the switch member 300 can be used to realize functions such as power switch or volume adjustment after being triggered by the button 200. Since the switch member 300 cannot be triggered when the button 200 is in the second position, the phenomenon of accidentally touching the button 200 can be avoided.

[0072] Combination Figure 4 and Figure 5 As shown, in some embodiments, the switch member 300 includes a body portion 310 and a contact portion 320, and the two sides of the body portion 310 are respectively connected to the second groove wall 112 and the contact portion 320, and the contact portion 320 can trigger the corresponding function of the switch member 300 after being pressed. When the button 200 is in the first position, the second protrusion 220 is opposite to the contact portion 320. When the button 200 is in the second position, the second protrusion 220 is misaligned with the contact portion 320. Thereby, it can be ensured that the button 200 can be hidden in the carrier 100 and the second protrusion 220 can be ensured not to accidentally touch the contact portion 320.

[0073] Combination Figure 4 and Figure 5 As shown, in some embodiments, the button 200 has a third protrusion 230 on one side facing the second groove wall 112, and the third protrusion 230 includes a second abutting portion 231 for abutting against the first groove wall 111. The first protrusion 210 and the third protrusion 230 are symmetrically distributed on both sides of the second protrusion 220. Such a configuration can ensure that the forces at both ends of the button 200 are balanced, so that the button 200 can be pushed smoothly.

[0074] like Figure 2 As shown, in some embodiments, the first section 113 includes a sliding portion 117 and a guide portion 118, and the guide portion 118 gradually moves away from the outer surface 120 relative to the sliding portion 117 in the direction from the first position to the second position. When the key 200 slides from the first position to the second position, the second abutting portion 231 slides from abutting against the sliding portion 117 to abutting against the guide portion 118. It can be understood that the second abutting portion 231 also limits the key 200 to prevent the key 200 from being separated from the carrier 100. When the key 200 moves from the first position to the second position, the guide portion 118 also guides the key 200.

[0075] like Figure 2As shown, in some embodiments, the tendency of the guide portion 118 to move away from the outer surface 120 is the same as the tendency of the second section 114 to move away from the outer surface 120. With such a configuration, when the key 200 moves, it can be ensured that both ends of the key 200 move along the same moving trajectory, that is, keep synchronous movement, further prevent one end of the key 200 from tilting, and ensure that the key 200 can be completely hidden in the carrier 100. It should be noted that the second section 114 and the guide portion 118 can be in an arc shape with the same curvature, or in a bent shape with the same bending angle, etc., as long as the second section 114 and the guide portion 118 maintain the same shape and have the same tendency to move away from the outer surface 120.

[0076] like Figure 4 and Figure 5 As shown, in some embodiments, the key 200 includes a key cap portion 240, a pressing portion 250 and a guide portion 260 connected in sequence in the direction from the first groove wall 111 to the second groove wall 112. The first protrusion 210 is provided on the side of the guide portion 260 facing the second groove wall 112. The surface of the key cap portion 240 away from the guide portion 260 is corrugated. It should be noted that the side of the key cap portion 240 facing the pressing portion 250 can be connected to the pressing portion 250 through a clamping structure, for example, the key cap portion 240 is provided with a mounting groove, and a part of the pressing portion 250 is mounted in the mounting groove. The pressing portion 250 and the guide portion 260 can be fixed by bonding or the like, or can also be an integrally formed structure. By setting the surface of the key cap portion 240 away from the guide portion 260 to be corrugated, when the user pushes the key cap portion 240 to drive the key 200 to move as a whole, the friction between the user's finger and the key cap portion 240 can be increased, so that it is more convenient for the user to push the key 200 smoothly.

[0077] like Figure 1 and Figure 2 As shown, in some embodiments, the key assembly further includes a circuit board 600 and an adhesive member 700. The two sides of the adhesive member 700 are respectively bonded to the circuit board 600 and the groove wall of the groove 110 opposite to the through hole 130. The side of the circuit board 600 away from the adhesive member 700 is electrically connected to the switch member 300. It should be noted that the circuit board 600 in the embodiment of the present application can be a printed circuit board 600 or a flexible circuit board 600. Since the switch member 300 is electrically connected to the circuit board 600, the transmission of signals or instructions can be realized between the switch member 300 and the circuit board 600, so that when the switch member 300 is triggered, the switch member 300 can cooperate with the circuit board 600 to realize the corresponding functions of the switch member 300, such as power switch or volume adjustment.

[0078] Combination Figures 1 to 6As shown, on the other hand, an embodiment of the present application further provides an electronic device, and the electronic device includes a key assembly described in any one of the above embodiments of the present application. It should be noted that the composition and function of the key assembly in the electronic device are the same as the composition and function of the key assembly in the above embodiments of the present application, and belong to the same technical concept, so the embodiments of the present application will not be repeated. Since the key 200 can be pushed to the second position and hidden in the carrier 100, when the key 200 is hidden, it can prevent the user's hand or the clamping member from applying a squeezing force to the key 200, thereby avoiding damage to the key 200, extending the service life of the key assembly, and also improving the service life of the electronic device.

[0079] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
