[0031] Most current electronic products contain exposed buttons, so that users can achieve corresponding function control by pressing buttons. However, button design mainly tends to focus on waterproof sealing performance, and pays less attention to press sensitivity. In related technologies, due to the limitations of cumulative errors in the processing and assembly of parts, there are problems of pressing virtual positions or transitional contact between buttons and switch contacts, which reduces the pressing sensitivity and anti-collision safety, affecting the user's pressing experience during use.

[0032] The present disclosure provides a key assembly. Figure 1 is a schematic cross-sectional structure diagram of an electronic device in an exemplary embodiment of the present disclosure, Figure 2 is a schematic diagram of a partial exploded structure of an electronic device in an exemplary embodiment of the present disclosure, Figure 3 yes Figure 1 The schematic diagram of the partial enlarged structure of the key assembly AA is shown in FIG. Figure 1-Figure 3As shown, the key assembly 1 includes a mounting tube 13, a telescopic module 11 and a pressing module 12. The telescopic module 11 includes a connecting member 111, a first elastic member 113 and an abutting member 112. At least a portion of the connecting member 111 is movably assembled in the mounting tube 13 along the axial direction, and the abutting member 112 is movably connected to the connecting member 111 in the axial direction. The pressing module 12 includes a pressing body 121 and a second elastic member 122. The first portion 1211 of the pressing body 121 is fixedly connected to the connecting member 111 and elastically abuts against the abutting member 112 through the first elastic member 113. The second portion 1212 of the pressing body 121 abuts against the mounting tube 13 through the second elastic member 122.

[0033] Since the above-mentioned key assembly 1 is divided into two parts, the telescopic module 11 and the pressing module 12, each part includes an elastic member with a buffering effect. The first elastic member 113 can absorb the errors caused by the processing, assembly and use fatigue of each component, and ensure the real-time contact between the abutment 112 and the contact point. The second elastic member 122 can not only cooperate with the first elastic member 113 to make the expected exposed height of the pressing body 121 to ensure the pressing feel, but also prevent the impact force from directly acting on the abutment 112 through the pressing body 121, and use the elasticity of the first elastic member 113 and the second elastic member 122 to form anti-collision protection. In addition, the above-mentioned key assembly 1 has a compact structure and can effectively meet the assembly requirements in a small product space.

[0034] When the pressing body 121 of the above-mentioned key assembly 1 is subjected to external pressing force, the second elastic member 122 is compressed, and the pressing body 121 drives the connecting member 111 fixed thereto to move axially inward. The abutting member 112 associated with the pressing body 121 through the first elastic member 113 also moves axially inward with the abutment of the first elastic member 113, thereby achieving contact between the abutting member 112 and the switch contact. When the external pressing force is cancelled, the pressing body 121 and the connecting member 111 are both reset, and the abutting member 112 can still maintain a state of zero-gap contact with the switch contact under the action of the second elastic member 122, which helps to improve the pressing sensitivity.

[0035] The following is an exemplary description of the structure and assembly method of each part of the telescopic module 11 and the pressing module 12:

[0036] In some embodiments, the connector 111 may include a first section 1114, one end of the outer surface of the first section 1114 is provided with a limiting protrusion 1111, the first section 1114 is movably received in the mounting tube 13 from the first port of the mounting tube 13, and when the connector 111 is located at the limit position, the end of the mounting tube 13 abuts against the limiting protrusion 1111. The limiting protrusion 1111 can limit the limit position of the connector 111 after the pressing body 121 is reset, so as to avoid the problems such as the connector 111 and the mounting tube 13 being disengaged and separated during the relative movement.

[0037] In the above embodiment, at least one sealing ring 1112 may be assembled around the outer surface of the first section 1114, and the sealing ring 1112 is tightly sealed with the inner surface of the mounting pipe 13. The sealing ring 1112 can form a seal between the connector 111 and the mounting pipe 13, so that the sealing ring 1112 forms waterproof isolation on both sides in the axial direction, thereby improving the waterproof performance of the electronic device 2. For example, two sealing rings 1112 may be provided on the outer surface of the first section 1114 along the axial direction. By adjusting the assembly scheme and the number of the sealing rings 1112, the key assembly 15ATM waterproof performance can be obtained.

[0038] For example, the outer surface of the first section 1114 is provided with at least one circle of mounting grooves 1117, and the sealing ring 1112 is fixedly assembled in the mounting grooves 1117. Assembling the sealing ring 1112 in the mounting grooves 1117 can improve the assembly stability of the sealing ring 1112 and also help improve the sealing performance of the sealing ring 1112. In order to further improve the sealing performance, the sealing ring 1112 can be interference fit with the mounting grooves 1117 and the inner surface of the mounting pipe 13.

[0039] In some embodiments, the interior of the connecting member 111 may be provided with a first assembly space 1113, the first portion 1211 is fixedly assembled in the first assembly space 1113, the abutting member 112 is slidably inserted in the first assembly space 1113, and at least a portion of the abutting member 112 is exposed outside the connecting member 111. The abutting member 112 is slidably inserted in the first assembly space 1113 to help improve the stability and smoothness of the abutting member 112 during movement, so that the abutting member 112 located outside the connecting member 111 is accurately positioned and has stable pressure when abutting against the switch contact.

[0040] Among them, an external thread can be set on the first part 1211, and an internal thread can be set on the side wall surrounding the first assembly space 1113. The internal thread and the external thread are tightly matched, and can also be tightened by loosening green oil to ensure a precise assembly effect.

[0041] In some embodiments, the abutment member 112 may include a second section 1121, a third section 1122, and a limiting section 1123 located between the second section 1121 and the third section 1122, the limiting section 1123 abuts against the end limiting surface 1116 of the connecting member 111, the first elastic member 113 is assembled to the third section 1122, and at least a portion of the second section 1121 is exposed outside the connecting member 111. When the abutment member 112 is pushed by the first elastic member 113, the limiting section 1123 can abut against the end limiting surface 1116 of the connecting member 111 to prevent the abutment member 112 from coming out, and can also limit the exposed length of the second section 1121 and the abutment force acting on the switch contact. The first elastic member 113 is assembled to the third section 1122 to improve the stability of the first elastic member 113. When the first elastic member 113 is a spring, the spring can be sleeved on the third section 1122 to achieve stable assembly of the spring.

[0042] In some embodiments, a support opening 1115 may be provided at one end of the connecting member 111, an end surface of the support opening 1115 is an end limiting surface 1116, the second section 1121 extends from the support opening 1115, and the inner wall of the support opening 1115 cooperates with the second section 1121 in a circumferential limiting manner. The inner wall of the support opening 1115 can support and limit the second section 1121, which can prevent the abutment member 112 from shaking during movement, and improve the overall structural strength and reliability of the key assembly 1.

[0043] The axial length of the support opening 1115 may be greater than half of the second section 1121 to enhance the support effect.

[0044] In some embodiments, the second portion 1212 includes a second port, and the pressing body 121 is inserted into the mounting pipe 13 from the second port, and the pressing body 121 includes a key cap 1211a exposed from the mounting pipe 13. A step-type limiting structure is provided in the mounting pipe 13, and the second elastic member 122 abuts against the step-type limiting structure and the inner surface of the key cap 1211a respectively. The step-type limiting structure can be used as a limit for one end of the second elastic member 122. When the key cap 1211a is subjected to force, the second elastic member 122 is deformed due to the abutment of the step-type limiting structure, so that the pressing body 121 can generate a pushing motion and a resetting motion.

[0045] The pressing body 121 further includes a pressing rod 1211b disposed inside the button cap 1211a, and the second elastic member 122 can be assembled to the pressing rod 1211b to improve the assembly stability of the second elastic member 122. For example, when the second elastic member 122 is a spring, the spring can be sleeved on the pressing rod 1211b.

[0046] The first port and the second port of the installation pipe 13 are opposite to each other, the first section 1114 of the connecting member 111 is inserted from the first port, and the pressing body 121 is inserted from the second port.

[0047] The key cap 1211a can form a covering space, and the end section of the mounting tube 13 is accommodated in the covering space. The key cap 1211a can cover the end of the mounting tube 13 to prevent the mounting tube 13 and other structures of the key assembly 1 from being exposed, thereby improving the aesthetics of the key assembly 1 and the electronic device 2. In addition, when the key cap 1211a covers the end section of the mounting tube 13, the pressing area of ​​the key cap 1211a can be increased, thereby improving the pressing feel.

[0048] In the above embodiment, the button assembly 1 may further include a protective pad 14, which is disposed between the second elastic member 122 and the stepped limiting structure, so as to avoid wear caused by the contact between the second elastic member 122 and the mounting tube 13 through the protective pad 14, thereby improving the service life and structural accuracy. The material of the protective pad 14 may be PET.

[0049] It should be noted that the first elastic member 113 and / or the second elastic member 122 may be a spring, or a structure with elastic properties such as rubber, silicone, or spring sheet, and the present disclosure is not limited thereto.

[0050] The present disclosure further provides an electronic device 2, which includes a device body 21 and the above-mentioned button assembly 1, the device body 21 includes a middle frame 211 and a button switch 212, the mounting tube 13 is fixedly assembled on the middle frame 211, and the abutment 112 contacts and cooperates with the switch button.

[0051] For example, the middle frame 211 may be provided with an assembly hole 2111, the mounting tube 13 is fixedly assembled in the assembly hole 2111, a portion of the mounting tube 13 is located in the assembly hole 2111, a portion of the mounting tube 13 is provided with a first port is located inside the assembly hole 2111, and a portion of the mounting tube 13 is provided with a second port is located outside the assembly hole 2111, when the pressing module 12 and the telescopic module 11 are assembled in the mounting tube 13, a stable and balanced assembly effect can be obtained, and at the same time, the length of the pressing body 121 exposed outside the middle frame 211 is ensured. The middle frame 211 may be provided with an avoidance recess at the periphery of the assembly hole 2111 to avoid structural interference in the end area where the key cap covers the mounting tube 13 and during the pressing process, and at the same time, a smooth appearance surface effect is formed to improve the overall aesthetics of the electronic device 2.

[0052] Since the key assembly 1 is divided into two parts, the telescopic module 11 and the pressing module 12, each part includes an elastic member with a buffering effect. The first elastic member 113 can absorb the errors caused by the processing, assembly and use fatigue of each component, ensuring the real-time contact between the abutment member 112 and the contact point. The second elastic member 122 can not only cooperate with the first elastic member 113 to make the pressing body 121 exposed at the expected height, ensuring the pressing feel, but also form anti-collision protection.

[0053] It should be noted that the electronic device 2 involved in the present disclosure can be a wearable device such as a watch or a bracelet, or it can be a mobile phone, a tablet computer, a vehicle-mounted terminal, or a medical terminal. The present disclosure does not limit the type of the electronic device 2.

[0054] Taking the electronic device 2 as an example, the mounting pipe 13 of the button assembly 1 can be a bar pipe, the connecting member 111 can be a button rod, and the abutment member 112 can be a telescopic rod. When the pressing body 121 is subjected to external pressing force, the second elastic member 122 is compressed, and the pressing body 121 drives the button rod fixed thereto to move axially inward. The telescopic rod associated with the pressing body 121 through the first elastic member 113 also moves axially inward with the abutment of the first elastic member 113, thereby achieving contact between the telescopic rod and the switch contact. When the external pressing force is cancelled, the pressing body 121 and the button rod are both reset, and the telescopic rod can still maintain a state of zero-gap contact with the switch contact under the action of the second elastic member 122, which helps to improve the pressing sensitivity.

[0055] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure.
