[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] The technical solutions of the present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0028] Please refer to Figures 1 to 3 together, where Figures 1 to 3 only a part of the housing 10 of the electronic device 1 in is schematically shown. An embodiment of the present invention provides an electronic device 1, including a housing 10, a microswitch 11 and a button body 12. The housing 10 is provided with a first through hole 100 penetrating along the first direction X. A first limiting portion 101 and a second limiting portion 102 are arranged at intervals along the first direction X in the housing 10. The microswitch 11 is arranged in the housing 10. The button body 12 can slidably penetrate through the first through hole 100. The button body 12 is configured to be able to abut against the microswitch 11 under the action of pressing. A limiting connecting member 13 is provided at one end of the button body 12 located in the housing 10. The limiting connecting member 13 is located between the first limiting portion 101 and the second limiting portion 102. The limiting connecting member 13 is configured to limit the sliding stroke of the button body 12 in the first direction X.

[0029] In the electronic device 1 provided by the embodiment of the present utility model, the button body 12 can slide relative to the first through hole 100 on the housing 10 along the first direction X, so that the button body 12 abuts against or disengages from the micro switch 11. The user can trigger the micro switch 11 by pressing the button body 12. By providing a first limiting portion 101 and a second limiting portion 102 in the housing 10, when the limiting connecting member 13 moves in the first direction X, it will abut against the first limiting portion 101 or the second limiting portion 102, which can limit the moving stroke of the limiting connecting member 13 in the first direction X, thereby limiting the sliding stroke of the button body 12 in the first direction X. On the one hand, it can prevent the button body 12 from falling off the housing 10. On the other hand, it can prevent the stroke of the button body 12 when it retracts from being too large. When the electronic device 1 drops, even if the button body 12 is squeezed and retracted, due to the limiting effect of the limiting connecting member 13 and the first limiting portion 101 or the second limiting portion 102, the button body 12 can at most trigger the micro switch 11, thereby avoiding excessive squeezing of the micro switch 11 and further avoiding the situation of damage to the micro switch 11.

[0030] Optionally, the electronic device 1 can be a smart watch, a mobile phone, a tablet, etc., which can be specifically selected according to the actual situation and is not specifically limited in this embodiment.

[0031] Exemplarily, when the electronic device 1 is a smart watch, the housing 10 of the electronic device 1 can be the middle frame of the smart watch, and the button body 12 is used as a side button of the electronic device 1.

[0032] Optionally, the first limiting portion 101 and the second limiting portion 102 can be in a plate-like structure, a block-like structure or the inner wall surface of the housing 10, etc., which can be specifically selected according to the actual situation and is not specifically limited in this embodiment.

[0033] Please refer to Figure 1 , in some embodiments, the inner wall surface of the housing 10 forms the first limiting portion 101, the first through hole 100 penetrates through the inner wall surface of the housing 10, the second limiting portion 102 protrudes from the housing 10, the second limiting portion 102 is provided with an avoidance portion 103 penetrating through itself along the first direction X, and the button body 12 passes through the avoidance portion 103.

[0034] In this way, by setting the inner wall surface of the housing 10 as the first limiting portion 101, the structure reuse can be realized, the number of components of the electronic device 1 can be reduced, and the structure of the electronic device 1 can be simplified. The second limiting portion 102 protrudes from the housing 10, and the avoidance portion 103 is provided on the second limiting portion 102, so that the button body 12 can pass through the avoidance portion 103 to abut against the micro switch 11. At the same time, the first through hole 100 and the avoidance portion 103 can jointly support and guide the button body 12, making the movement of the button body 12 in the first direction X relatively stable.

[0035] Optionally, the avoidance portion 103 may be a through hole, or the avoidance portion 103 may be a groove, which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0036] Optionally, the avoidance portion 103 is disposed on one side of the second limiting portion 102 in the circumferential direction around the first direction X. In this way, the avoidance portion 103 can be configured as a groove, and the volume of the second limiting portion 102 can be configured to be relatively small, thereby reducing the overall weight of the housing 10 .

[0037] For example, Figure 1 As shown, the second limiting portion 102 is a stopper protruding from the inside of the shell 10, and the top end surface of the second limiting portion 102 can be roughly flush with or lower than the plane where the central axis of the first through hole 100 is located, so that it is convenient to directly set the avoidance portion 103 on the top end surface of the second limiting portion 102, which is convenient for the key body 12 to pass through. At the same time, the second limiting portion 102 has a suitable height and can also reduce the second limiting portion 102 The internal space occupied by the shell 10 and reduce the impact on the arrangement of other components inside the shell 10.

[0038] Optionally, the limiting connector 13 may be integrally provided with the key body 12, for example, the limiting connector 13 is a convex portion on the key body 12. Alternatively, the limiting connector 13 may be separately provided with the key body 12, for example, the limiting connector 13 may be a washer, which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0039] See also Figure 3 For example, a card slot 1200 extending circumferentially along the straight line where the first direction X is located is provided on the button body 12 , and the limiting connecting member 13 is a gasket, and the limiting connecting member 13 is sleeved in the card slot 1200 .

[0040] In this way, by providing a card slot 1200 on the key body 12, the limiting connecting member 13 can be sleeved in the card slot 1200, so that the limiting connecting member 13 is fixed relative to the key body 12 in the first direction X, and it is convenient for the installation of the limiting connecting member 13. By setting the limiting connecting member 13 as a washer, when the key body 12 moves and the limiting connecting member 13 abuts against the first limiting portion 101 and the second limiting portion 102, the limiting connecting member 13 can play a buffering role, reducing the impact force when the limiting connecting member 13 contacts the first limiting portion 101 and the second limiting portion 102, thereby improving the service life of the limiting connecting member 13, the first limiting portion 101 and the second limiting portion 102. At the same time, setting the washer as the limiting connecting member 13 makes the structure of the electronic device relatively simple, and the installation method of the limiting connecting member 13 and the key body 12 is also relatively simple. It only needs to sleeve the washer on the key body 12, which simplifies the structural design of the electronic device 1 and reduces the difficulty of component assembly.

[0041] In this embodiment, when the avoidance hole is a groove and the avoidance portion 103 is provided on one side of the second limiting portion 102 in the circumferential direction around the first direction X, it is convenient for the installation of the key body 12 and the limiting connecting member 13. Specifically, the limiting connecting member 13 can be first placed between the first limiting portion 101 and the second limiting portion 102, and then the key body 12 is passed through the first through hole 100 and the groove until the card slot 1200 is located between the first limiting portion 101 and the second limiting portion 102. Finally, the limiting connecting member 13 is sleeved on the card slot 1200. Since the avoidance portion 103 is provided on one side of the second limiting portion 102 in the circumferential direction around the first direction X, the avoidance portion 103 will also avoid a part of the first limiting portion 101, thereby facilitating the operator to place the limiting connecting member 13 and facilitating the operator to observe the position of the limiting connecting member 13, so that the center of the limiting connecting member 13 is aligned with the center of the first through hole 100, thus facilitating the key body 12 to pass through the first through hole 100 and the limiting connecting member 13 at the same time.

[0042] Optionally, the washer can be a C-shaped washer. When installing the key body 12 and the limiting connecting member 13, the key body 12 can be first passed through the first through hole 100 and the groove until the card slot 1200 is located between the first limiting portion 101 and the second limiting portion 102, and then the limiting connecting member 13 is directly sleeved on the card slot 1200. The installation method is relatively simple.

[0043] In some embodiments, in the first direction X, the thickness of the limiting connecting member 13 is d1, the stroke of the micro switch 11 is d2, and the distance between the first limiting portion 101 and the second limiting portion 102 is d3, and d1 + d2 = d3. Wherein, the stroke of the micro switch 11 refers to the moving distance required for the key body 12 to press and trigger the micro switch 11 until the key body 12 completely disengages from the trigger switch.

[0044] In this way, the maximum travel of the limit connecting member 13 between the first limit member and the second limit member is d2, that is, the maximum travel of the key body 12 in the first direction X is the travel of the micro switch 11. This can ensure that the key body 12 can trigger the micro switch 11 while preventing the micro switch 11 from being damaged by multiple collisions with the key body 12 when the electronic device 1 falls.

[0045] Figure 3 The dotted line in the figure indicates the elastic member 122. In some embodiments, the key body 12 includes a connecting rod 120 and a key cap 121, the connecting rod 120 is slidably connected to the first through hole 100, the key cap 121 is connected to one end of the connecting rod 120 away from the micro switch 11, the electronic device 1 also includes an elastic member 122, one end of the elastic member 122 is connected to the housing 10, the other end of the elastic member 122 is connected to the key cap 121, and the elastic member 122 is used to provide an elastic reset force.

[0046] In this way, when the user presses the keycap 121, the keycap 121 drives the connecting rod 120 to slide along the first direction X and abut against the micro switch 11. At this time, the elastic member 122 is compressed to generate elastic force. After the user releases the keycap 121, the elastic member 122 provides elastic restoring force to the keycap 121, so that the keycap 121 drives the connecting rod 120 to slide along the first direction X and disengage from the micro switch 11.

[0047] Optionally, the elastic member 122 may be a spring or a spring sheet, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0048] In some embodiments, a receiving groove 1210 is provided on one side of the keycap 121 facing the housing 10, the receiving groove 1210 is arranged circumferentially along the first direction X, and the elastic member is at least partially arranged in the receiving groove 1210. In this way, by arranging at least a portion of the elastic member in the receiving groove 1210, the elastic member can be shielded, the neatness of the appearance of the electronic device 1 is improved, and at the same time, the elastic member can be protected.

[0049] In some embodiments, the electronic device 1 further includes a buffer component 14, and the buffer component 14 is connected between the key body 12 and the micro switch 11. In this way, by arranging the buffer component 14 between the key body 12 and the micro switch 11, the key body 12 is indirectly in contact with the micro switch 11 through the buffer component 14, and when the key body 12 is pressed or collided, the buffer component 14 can buffer the movement of the key body 12, thereby reducing the impact force on the micro switch 11, protecting the micro switch 11, reducing the risk of damage to the micro switch 11, and increasing the service life of the micro switch 11.

[0050] Optionally, the buffer component 14 may be a silicone sheet or a gasket, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0051] See also Figure 4 In some embodiments, a mounting seat 15 is further provided in the housing 10, and the mounting seat 15 is provided with a first step portion 150 and a second step portion 151, the first step portion 150 and the second step portion 151 are arranged along the first direction X, the micro switch 11 is arranged on the first step portion 150, and the buffer component 14 is arranged on the second step portion 151. In this way, by arranging the first step portion 150 and the second step portion 151 on the mounting seat 15, the micro switch 11 and the buffer component 14 can be supported, and the positioning and installation of the micro switch 11 and the buffer component 14 on the mounting seat 15 are facilitated.

[0052] In some embodiments, the mounting seat 15 is further provided with a first abutment portion 152, which is located on the side of the second step portion 151 away from the first step portion 150, and the electronic device 1 also includes a second abutment portion 16, which is protruding from the shell 10, and the second abutment portion 16 and the first abutment portion 152 are spaced apart along the first direction X, and the second abutment portion 16 and the first abutment portion 152 are used to limit the position of the buffer component 14 in the first direction X.

[0053] In this way, the second abutment portion 16 and the first abutment portion 152 can jointly limit the position of the buffer component 14 in the first direction X, thereby preventing the buffer component 14 from falling off from between the micro switch 11 and the button body 12 during the use of the electronic device 1. In addition, the first abutment portion 152, the first step portion 150 and the second step portion 151 are all arranged on the mounting seat 15, that is, arranged on the same component, so that the structure of the electronic device 1 is more compact.

[0054] Optionally, the first abutting portion 152 may be a block-shaped structure or a plate-shaped structure protruding from the mounting seat 15 , which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0055] Optionally, the second abutting portion 16 may be a block structure or a plate structure, and the second abutting portion 16 may be a separately provided component or may be provided integrally with the housing 10, which may be selected according to actual conditions and is not specifically limited in this embodiment. Figure 4 As shown, the second abutment portion 16 is a plate-like structure integrally provided with the housing 10 , and the housing 10 can extend along the first direction X to form the second abutment portion 16 , without the need to separately provide additional components, thereby making the structure of the electronic device 1 relatively simple and reducing the difficulty of component assembly.

[0056] In some embodiments, the number of the mounting seats 15 is two, and the two mounting seats 15 are arranged at intervals in a direction perpendicular to the first direction X. In this way, it can not only ensure a good supporting effect on the micro switch 11 and the buffer member 14, but also reduce the volume of the mounting seats 15, thereby facilitating the light weight of the electronic device 1.

[0057] Please refer to Figure 5 , in some embodiments, the buffer member 14 is provided with a positioning groove 140, and the positioning groove 140 is snap-fitted to the second step portion 151. In this way, the positioning groove 140 of the buffer member 14 can be snap-fitted to the second step portion 151, so that in the direction perpendicular to the first direction X, the buffer member 14 and the second step portion 151 can be fixed to each other, avoiding the situation that the buffer member 14 moves relative to the second step portion 151 and disengages between the micro switch 11 and the button body 12.
