In an implementation, the frame10has an outer side surface14and an inner side surface15opposite to the outer side surface14. In an example, the outer side surface14of the frame10is at an outside of the frame10, and the inner side surface15of the frame10is at an inside of the frame10. The inner side surface15may be composed of flat surfaces and non-flat surfaces. That is, the inner side surface15of the frame10may have multiple recessions and multiple protrusions in such a way that the inner side surface15of the frame10can match various components. The inner side surface15is an interface of the frame10that can substantially enclose to define an inner space. The outer side surface14may be composed of flat surfaces and non-flat surfaces. That is, the outer side surface14may also have multiple recessions and multiple protrusions. The outer side surface14substantially forms the appearance surface of the frame10. The inner side surface15encloses to form an accommodating space150. The accommodating space150is used for accommodating various functional components such as a mainboard, a signal trigger, a camera, a sensor, a memory, an antenna, and the like.

The frame10further has a first end surface16and a second end surface17opposite to the first end surface16. The inner side surface15and the outer side surface14are in connection with the first end surface16and the second end surface17. In an example, the first end surface16and the second end surface17are disposed between the outer side surface14and the inner side surface15. The button hole11extends from the outer side surface toward the inside of the frame10and is located between the first end surface16and the second end surface17, and the pin hole12extends from the first end surface16or the second end surface17to the inner side wall of the button hole11. The first end surface16can match front structural members of the electronic device100. The second end surface17can match rear structural members of the electronic device100. The front structural members refer to structural members facing a user of the electronic device100when the electronic device100is in use. The rear structural members refer to structural members facing away from the user of the electronic device100when the electronic device100is in use. For example, the front structural members include a display screen, and the rear structural members include a rear cover. The first end surface16and the second end surface17may both be composed of flat surfaces and non-flat surfaces. That is, the first end surface16and the second end surface17may both have multiple recessions and protrusions.

In this implementation, the button hole11extends from the outer side surface14toward the inner side surface15. The button hole11has a button opening111defined on the outer side surface14. The button30is inserted into the button hole11from the button opening111. The button hole11further has an inner circumferential wall extending from the button opening111toward the inner side surface15. The inner circumferential wall is in clearance fit with an outer circumferential wall of the button30. The inner circumferential wall can also provide slidable guide to the button30, so as to prevent the button30from being lifted up. The pin hole12penetrates the inner circumferential wall. The stop pin20extends into the button hole11through an opening of the pin hole12that penetrates the inner circumferential wall.

The inner circumferential wall has two long inner side surfaces112substantially parallel to the first end surface16or the second end surface17, a first short inner side surface113, and a second short inner side surface114opposite to the first short inner side surface113. The first short inner side surface113and the second short inner side surface114are connected with the two long inner side surfaces112. The stop protrusion13extends from the first short inner side surface113. The pin hole12penetrates the long inner side surfaces112and is adjacent to the second short inner side surface114. Part of the stop pin20extending into the button hole11is adjacent to the second short inner side surface114. The stop pin20can penetrate the long inner side surface112.

Optionally, the button hole11is square. The button hole11has two inner side walls opposite to one another. The stop protrusion13is disposed on one of the two inner side walls. The stop pin20is adjacent to the other of the two inner side walls opposite to the stop protrusion13.

Optionally, the button hole11is circular. The stop protrusion13and the stop pin20are approximately symmetrically arranged about the central axis of the button hole11.

Optionally, the frame10is circular. The button30is disposed on a circumferential side of the frame10. Alternatively, the frame10defines multiple button holes11in a circumferential direction, and the electronic device100may also include multiple buttons30mounted in the button holes11respectively.

During installation of the button30, the first hook31of the button30first hooks the stop protrusion13, the second hook32is then inserted into the button hole11, and the second hook32is caused to be at a side of the pin hole12away from the button opening111, and finally the stop pin20is inserted into the pin hole12, so that the second hook32can hook the stop pin20.

Further, the button30is provided with a button cap33and a button post34connected with the button cap33. The button cap33matches the button hole11. The first hook31and the second hook32are respectively disposed at both ends of the button cap33in a length direction of the button cap. The button post34is connected with the button cap33and located between the first hook31and the second hook32. The button post34is connected with the button cap33at an inner side of the button cap33close to the frame10.

Specifically, an outer circumferential wall of the button cap33is in clearance fit with the inner circumferential wall of the button hole11. The button cap33has an outer end surface331, an inner end surface332opposite to the outer end surface331, and an outer circumferential surface connected between the outer end surface331and the inner end surface332. The outer circumferential surface has a first short outer side surface333, a second short outer side surface334opposite to the first short outer side surface333, and two long outer side surfaces connected between the first short outer side surface333and the second short outer side surface334. The first short outer side surface333matches the first short inner side surface113and the second short outer side surface334matches the second short inner side surface114. The two long outer side surfaces match the long inner side surfaces112. The inner end surface332is inside the button hole11and away from the button opening111. The first hook31and the second hook32extend from the inner end surface332. The first hook31is close to the first short outer side surface333and the second hook32is close to the second short outer side surface334.

Optionally, as illustrated inFIG.4, the frame10is arc-shaped. The button cap33is an arc-shaped curved plate. The button cap33matches the frame10in shape, so that the button cap33can have an increased length, and the button cap33can be connected with the button posts34at multiple positions. As such, various parts of the button cap33can be pressed, and various manipulations can be realized through multiple button posts34.

The button post34has a length direction which is substantially perpendicular to the inner side surface15and the outer side surface14of the frame10, such that it is convenient for the button post34to receive a pressing force applied by the button cap33to slide in a direction perpendicular to the inner side surface15and the outer side surface14of the frame10, and it can make a sliding force of the button post34focus on the signal trigger60inside the frame10. The button post34is connected to the inner end surface332and is located between the first hook31and the second hook32. The first hook31and the second hook32exert a balanced limiting force on the button cap33to prevent the button cap33from being lifted up.

Optionally, when the button30is not pressed, a surface of the button cap33away from the button post34may protrude relative to the outer side surface14, such that the button cap33is easily to be perceived when the user touches an outer side of the frame10, and it is convenient for the user to press the button cap33.

Optionally, when the button30is not pressed, the surface of the button cap33away from the button post34may be substantially flush with the outer side surface14to improve flatness of outer structures of the frame10.

Optionally, when the button30is not pressed, the surface of the button cap33away from the button post34can be recessed relative to the outer side surface14to prevent the button30from being impacted when the electronic device100is dropped, so as to prevent the button30from being damaged.

Optionally, when the button30is not pressed, an end surface of the button post34away from the button cap33may protrude relative to the inner side surface15, which facilitates an abutment (or, contact) between the button post34and the signal trigger60.

Optionally, when the button30is not pressed, the end surface of the button post34away from the button cap33may be flush with the inner side surface15to ensure the flatness of the interior structure of the frame10and improve the utilization rate of the accommodating space150.

Optionally, when the button30is not pressed, the end surface of the button post34away from the button cap33may be recessed relative to the inner side surface15. By receiving the pressing force applied by the button cap33, one end of the button post34protrudes relative to the inner side surface15to abut against the signal trigger60. In an implementation, by receiving the pressing force applied by the button cap33, one end of the button post34protrudes relative to the inner side surface15to be in contact with the signal trigger60, so that the signal trigger60can be triggered to send signals.

In another implementation, the button cap33can also be in a disc shape, and the button hole11is circular. The button cap33is provided with multiple first hooks31and multiple second hooks32, and each of the multiple first hooks31and each of the multiple second hooks32is symmetrically arranged around the geometric center of the button cap33. The geometric center axis of the button cap33is aligned with the geometric center axis of the button post34. There are multiple stop protrusions13disposed on the inner side wall of the button hole11, and multiple stop pins20penetrating through an inner wall of the button hole11. The button cap33can also be a triangular, polygonal, or other arbitrary shape plate.

Further, the first hook31has a first boss335extending from the inner side of the button cap33and a first transverse arm311extending from one end of the first boss335. The second hook32has a second boss336extending from the button cap33and a second transverse arm321extending from one end of the second boss336. The stop protrusion13is movable between the first transverse arm311and the button cap33. The stop pin20is movable between the second transverse arm321and the button cap33. In an example, the stop protrusion13is between the first transverse arm311and the button cap33, the stop pin20is between the second transverse arm321and the button cap33, the first transverse arm311and the button cap33are movable relative to the stop protrusion, and the second transverse arm321and the button cap33are movable relative to the stop pin.

In this implementation, the first boss335and the second boss336perpendicularly extend from the inner end surface332in a direction away from the outer end surface331. The first boss335is spaced apart from the first short outer side surface333and the second boss336is spaced apart from the second short outer side surface334. The first transverse arm311extends from one side of the first boss335away from the second boss336. The second transverse arm321extends from one side of the second boss336away from the first boss335. One end of the first transverse arm311away from the first boss335is approximately aligned with the first short outer side surface333. One end of the second transverse arm321away from the second boss336is approximately aligned with the second short outer side surface334. The first transverse arm311and the inner end surface332define a first chute therebetween. The second transverse arm321and the inner end surface332define a second chute therebetween. The stop protrusion13can slide in the first chute. The stop pin20can slide in the second chute. A displacement of the stop protrusion13relative to the first chute is equal to a pressing sliding distance of the button cap33. Alternatively, a displacement of the stop pin20relative to the second chute is equal to a pressing sliding distance of the button cap33. It can be understood that, both the first hook31and the second hook32can be integrally formed with the button cap33, which makes the button30simple in structure and easy to manufacture, and the button30and the frame10easy to assemble.

Further, referring toFIG.5andFIG.6, the button hole11has a bottom wall115opposite to the button cap33. The first boss335defines a first groove337with an opening facing the bottom wall115. The second boss336defines a second groove338with an opening facing the bottom wall115. The button30further includes a first elastic member35and a second elastic member36. The first elastic member35is partially received in the first groove337and the second elastic member36is partially received in the second groove338. The first elastic member35extends beyond one end of the first groove337and elastically abuts against the bottom wall115. The second elastic member36extends beyond one end of the second groove338and elastically abuts against the bottom wall115.

In this implementation, the first groove337extends from an end surface of the first boss335toward the inner end surface332. The second groove338extends from an end surface of the second boss336toward the inner end surface332. Both the first elastic member35and the second elastic member36are rectangular springs. The first elastic member35is fixed in the first groove337at one end of the first elastic member35, and abuts against the bottom wall115at the other end of the first elastic member35. The second elastic member36is fixed in the second groove338at one end of the second elastic member36, and abuts against the bottom wall115at the other end of the second elastic member36. Both the first elastic member35and the second elastic member36are used to provide the button cap33with elastic restoring forces in a direction away from the bottom wall115. When the button cap33is pressed, the first elastic member35and the second elastic member36are compressed, the button cap33is moved toward the bottom wall115, and the button post34can trigger the signal trigger60. When the pressing force applied on the button cap33is removed, the elastic restoring forces of the first elastic member35and the second elastic member36exert on the button cap33and make the button cap33slide away from the bottom wall115. When the first transverse arm311abuts against the stop protrusion13and the second transverse arm321abuts against the stop pin20, the first elastic member35and the second elastic member36are in a pre-compressed state, so that the button30remains in a pressable state.

Optionally, at least one of the first elastic member35or the second elastic member36is a rectangular spring.

Optionally, at least one of the first elastic member35or the second elastic member36is a torsion spring.

Optionally, at least one of the first elastic member35or the second elastic member36is an elastic silicone block or an elastic rubber block.

Further, the frame10defines a button-post guide hole116penetrating the bottom wall115. The button-post guide hole116is in clearance fit with the button post34. The button30is provided with a sealing ring37which is fastened to a circumferential side of the button post34and sealingly matches the button-post guide hole116.

In this implementation, the button-post guide hole116extends from the inner side surface15to the bottom wall115. The button-post guide hole116serves as a pressing-sliding guide structure of the button30, so that the button post34can maintain a slide in a fixed direction aligned with the signal trigger60. The button-post guide hole116penetrates the inner side surface15so that one end of the button post34can pass through the inner side surface155of the frame10under a pressing action of the button cap33. Specifically, the bottom wall115is provided with an extension boss matching the first boss335and the second boss336, and the button-post guide hole116penetrates the extension boss, so as to increase a depth of the button-post guide hole116and a guiding stability of the button post34.

Optionally, the length of the button post34is greater than the depth of the button-post guide hole116, which ensures that one end of the button post34can move out of the button-post guide hole116.

Optionally, one end of the button-post guide hole116away from the inner side surface15is substantially adjacent to the outer side surface14, such that most of the button cap33is exposed to the outside of the outer side surface14, and it is convenient for the button cap33to receive the pressing force.

Optionally, one end of the button-post guide hole116away from the inner side surface15is substantially located at a middle position between the outer side surface14and the inner side surface15, thus, there is a safety distance between the button-post guide hole116and the outer side surface14, so as to prevent dust and impurities outside the frame10from entering the button-post guide hole116to interfere with sliding of the button post34relative to the frame10.

In this implementation, the sealing ring37is elastically deformable. The sealing ring37in a free state has an outer diameter greater than an inner diameter of the button-post guide hole116. When the sealing ring37is inserted into the button-post guide hole116along with the button post34, the sealing ring37will be compressed and deformed under compression action of the inner circumferential wall of the button-post guide hole116, so that the sealing ring37can be in close contact with the inner circumferential wall of the button-post guide hole116to a large extent, and the sealing ring37can seal a gap between the inner circumferential wall of the button-post guide hole116and the outer circumferential wall of the button post34. The sealing ring37can effectively prevent water, dust, and impurities from entering the inside of the frame10through the gap between the outer circumferential wall of the button post34and the inner circumferential wall of the button-post guide hole116. For example, the electronic device100is a smart watch, and the electronic device100uses the sealing ring37to seal the gap between the button post34and the inner circumferential wall of the button-post guide hole116, so that the electronic device100can meet 5 atmospheres (ATMs) waterproof requirement.

In an implementation, the button post34defines a clamping groove along a circumferential direction at one end of the button post34away from the button cap33. The clamping groove has a width which is substantially equal to a difference between the outer diameter and the inner diameter of the sealing ring37. The sealing ring37is sleeved on the button post34. The sealing ring37is partially clamped into the clamping groove. The sealing ring37is detachably connected with the button post34to facilitate disassembly and maintenance of the sealing ring37. When mounting the button30to the frame10, the sealing ring37is first sleeved on the button post34, and then the button post34and the sealing ring37are integrally inserted into the button-post guide hole116.

Optionally, the sealing ring37and the button post34are formed integrally to increase tightness between the sealing ring37and the button post34.

Optionally, the sealing ring37is made of silicone to improve elastic sealing performance and friction resistance of the sealing ring37.

Optionally, the sealing ring37is made of rubber to prolong the service life of the sealing ring37.

Further, the button30is further provided with an elastic cushion38, and the elastic cushion38is elastically connected with the button post34and the button cap33.

In conventional technical schemes, the button cap33and the button post34of the button30are formed integrally, or are firmly fixed together by other means. Generally, the button cap33has a relative large length between two ends. When pressing one end of the button cap33, the other end will be lifted up. At the same time, the electronic device100is provided with a guide structure for slidably guiding the button post34. When the button cap33is tilted up, it is easy to cause the button post34and the guide structure to be non-coaxial and in turn cause the button30to be stuck. Therefore, the button30and the button cap33are designed to form separately, and the button cap33is movably connected with the button post34, which is beneficial to allowing the button cap33to withstand various pressing forces in various forms. As such, even if the button cap33is tilted up, it will not cause the button post34to be non-coaxial with the guide structure, and the availability of the button30is ensured. In an implementation, the guide structure is a through hole.

In implementations of the disclosure, the elastic cushion38is connected between the button cap33and the button post34, the elastic deformation performance of the elastic cushion38allows the button cap33to be movable relative to the button post34, such that the button post34is prevented from being stuck due to tilt-up of the button post34, failure of the button30can be prevented, the effective pressing performance of the button30can be ensured, and the service life of the button30can be prolonged.

In this implementation, the button cap33, the elastic cushion38, and the button post34are sequentially stacked, and integrally extend through the frame10. The button cap33is adjacent to the outer side surface14of the frame10. The button post34is adjacent to the inner side surface15of the frame10. The button post34is at least partially located between the outer side surface14and the inner side surface15, which is beneficial for supporting button post34and pressing and directing the button post34by the frame10. The elastic cushion38is located between the outer side surface14and the inner side surface15.

During assembling of the button30, the button post34and the sealing ring37are first penetrated into the button-post guide hole116, such that one end of the button post34is aligned with the signal trigger60inside the frame10. The elastic cushion38is then fixed to the other end of button post34away from the signal trigger60, such that the button post34is securely connected with the elastic cushion38. And then, the first hook31of the button cap33hooks the stop protrusion13, and the button cap33is firmly connected to the elastic cushion38. Finally, the second hook32is inserted into the button hole11, and the stop pin20is inserted into the pin hole12, so that the second hook32hooks the stop pin20.

The elastic cushion38is substantially perpendicular to the length direction of the button post34. The elastic cushion38is attached to the end surface of the button post34at one surface of the elastic cushion38which has a relatively large area. A surface of the button cap33close to the button post34is attached to the other surface of the elastic cushion38which has a relatively large area. The button cap33completely covers the elastic cushion38to ensure effective contact between the button cap33and the elastic cushion38.

It is understood that, when a direction of a pressing force exerted on the button cap33is inclined relative to the button post34, one end of the button cap33will be lifted up, one end of the elastic cushion38is compressed while the other end of the elastic cushion38is stretched. In other words, when the direction of the pressing force exerted on the button cap33is not parallel to a length direction of the button cap33, one end of the elastic cushion38is compressed while the other end of the elastic cushion38is stretched. That is, the elastic cushion38absorbs an inclined force (i.e., a force which is not parallel to the length direction of the button post34) applied by the button cap33, which prevents the inclined force from being transferred to the button post34, and in turn prevents the button post34from tilting. The elastic cushion38is connected with the button post34and the button cap33, such that the button cap33is spaced apart from the button post34. The length direction of the button post34can remain aligned with the signal trigger60. As such, the button post34can effectively trigger the signal trigger60and can be reset effectively to avoid being stuck.

Optionally, one surface of the elastic cushion38connected with the button post34completely covers the end surface of the button post34.

Optionally, one surface of the elastic cushion38connected with the button post34partially covers the end surface of the button post34.

In implementations of the disclosure, the elastic cushion38is made of silicone. The elastic cushion38may be bonded with the button post34and the button cap33via double-sided adhesive.

Optionally, the elastic cushion38may also be made of metal. The elastic cushion38can be fixedly bonded to the button cap33and the button post34via glue.

Optionally, the elastic cushion38may also be an elastic foam sheet.

Further, the button cap33defines a fixing groove337. The elastic cushion38is partially fixed within the fixing groove337. The button cap33defines the fixing groove337between the first boss335and the second boss336. The elastic cushion38is partially fixed inside the fixing groove337to increase the stability between the elastic cushion38and the button cap33. Due to the compressibility of the elastic cushion38, the elastic cushion38can effectively compensate a tolerance between the button cap33and the button post34, so that the button30can work normally within the tolerance. Due to the cushioning performance of the elastic cushion38, even under extreme conditions, an impact force applied on the button30during a collision can be transferred to and absorbed by the elastic cushion38without being transferred to the button post34to cause an impact to the signal trigger60, which helps to avoid the failure of the electronic device100when the electronic device100is dropped, to prolong the service life of the electronic device100.

Optionally, the elastic cushion38is bonded in the fixing groove337via glue. The fixing groove337can also prevent the glue from overflowing.

Optionally, the elastic cushion38can also be completely fixed in the fixing groove337.

Further, referring toFIG.7, the electronic device100further includes a display screen assembly40matching the first end surface16of the frame10and a rear cover50matching the second end surface17.

In this implementation, the display screen assembly40further includes a transparent cover plate41matching the first end surface16and a display screen42attached to the transparent cover plate41and located inside the frame10.
