Technical Field

[0001] This application belongs to the technical field of wearable devices, and particularly relates to a wearable device. Background Art

[0002] In related technologies, wearable devices have started to enter our lives. In particular, smart watches and bracelets worn on the wrist are very popular. Especially, more and more people participate in sports and health through wearable devices, meeting people's pursuit of health. Currently, wearable devices with detection functions are also becoming more and more popular.

[0003] A wearable device with a detection function generally has four electrodes. Two of the electrodes are arranged on the back cover of the wearable device and are in contact with the skin for detection. The other two electrodes are arranged on two buttons, and conduction detection is completed by contacting them with two fingers.

[0004] However, in the actual use process of this button structure form, the height of the button protrusion is often too short, resulting in the fingers also contacting the metal shell at the same time, seriously affecting the detection accuracy. Summary of the Invention

[0005] This application aims to provide a wearable device, at least solving the problem of low detection accuracy of existing wearable devices.

[0006] To solve the above technical problems, this application is implemented as follows:

[0007] In a first aspect, an embodiment of this application provides a wearable device, which includes:

[0008] A housing having an inner cavity, and a first button hole and a second button hole communicating with the inner cavity are formed on the housing;

[0009] A first button disposed in the first button hole;

[0010] A second button disposed in the second button hole;

[0011] A limiting device disposed in the inner cavity, the limiting device cooperates with a first limiting portion of the first button to limit the first button from moving outward of the housing, and the limiting device cooperates with a second limiting portion of the second button to limit the second button from moving outward of the housing;

[0012] When the wearable device is in the first state, the first button is in the first position, the second button is in the second position, the limiting device is disengaged from the first limiting portion of the first button, and the limiting device is disengaged from the second limiting portion of the second button, so that the first button and the second button can move outwardly with respect to the housing;

[0013] When the wearable device is in the second state, the first button and the second button move outwardly with respect to the housing by a first distance, the first button is in the third position, the second button is in the fourth position, the limiting device cooperates with the third limiting portion of the first button to limit the first button from moving outwardly with respect to the housing, and the limiting device cooperates with the fourth limiting portion of the second button to limit the second button from moving outwardly with respect to the housing.

[0014] In an embodiment of the present application, when the wearable device is in the second state, the first button and the second button can move outwardly with respect to the housing by a first distance, increasing the height dimension of the first button and the second button protruding from the housing, so as to facilitate touching the first button and the second button for relevant detection, avoid the fingers touching the housing while touching, and improve the accuracy of detection.

[0034] The following Figures 1 - 11 describes a wearable device according to an embodiment of this application.

[0035] As Figures 1 - 11 shown, a wearable device according to some embodiments of this application, the wearable device includes:

[0036] A housing 1, the housing 1 has an inner cavity 10, and a first button hole 31 and a second button hole 32 communicating with the inner cavity 10 are formed on the housing 1;

[0037] A first button 21, the first button 21 is disposed in the first button hole 31;

[0038] A second button 22, the second button 22 is disposed in the second button hole 32;

[0039] A limiting device is provided in the inner cavity 10. The limiting device cooperates with the first limiting portion 51 of the first button 21 to limit the outward movement of the first button 21 relative to the housing 1. The limiting device also cooperates with the second limiting portion 52 of the second button 22 to limit the outward movement of the second button 22 relative to the housing 1. The state where the limiting device cooperates with the first limiting portion 51 and the second limiting portion 52 to limit the outward movement of the first button 21 and the second button 22 is the original state of the wearable device.

[0040] When the wearable device is in the first state, the first button 21 is in the first position and the second button 22 is in the second position. The limiting device disengages from the first limiting portion 51 of the first button 21 and disengages from the second limiting portion 52 of the second button 22, enabling the first button 21 and the second button 22 to move outward relative to the housing 1.

[0041] When the wearable device is in the second state, the first button 21 and the second button 22 move outward relative to the housing 1 by a first distance. The first button 21 is in the third position and the second button 22 is in the fourth position. The limiting device cooperates with the third limiting portion 71 of the first button 21 to limit the outward movement of the first button 21 relative to the housing 1, and the limiting device cooperates with the fourth limiting portion 72 of the second button 22 to limit the outward movement of the second button 22 relative to the housing 1. As Figure 7 shown, it is the state after the first button 21 and the second button 22 have moved outward relative to the housing 1 by a first distance.

[0042] In the embodiments of the present application, when the wearable device is in the second state, the first button 21 and the second button 22 can move outward relative to the housing 1 by a first distance, increasing the height dimension of the first button 21 and the second button 22 protruding from the housing 1. This facilitates touching the first button 21 and the second button 22 for relevant detections, avoids the fingers touching the housing 1 simultaneously, and improves the accuracy of the detections.

[0043] In the wearable device of the present application, multiple buttons are provided to trigger health detections for the user. The health detections can be body fat detections, blood pressure detections, etc. For example, the detection function is achieved by the user touching the first button 21 and the second button 22.

[0044] This application restricts the positions of the first button 21 and the second button 22 through a limiting device. For example, the limiting device can be a control device that is separately connected and capable of controlling the movement of the first button 21 and the second button 22. For example, the control device is connected to the first button 21 and the second button 22 through a transmission structure, and drives the first button 21 and the second button 22 to move through transmission. For example, in the first state, the control device controls the first button 21 to remain in the first position and the second button 22 to remain in the second position. In the second state, the control device controls the first button 21 to remain in the third position and the second button 22 to remain in the fourth position. Compared with the first position in the second state, the first button 21 and the second button 22 protrude more from the outside of the housing 1, so that when the wearable device switches from the first state to the second state, the first button 21 and the second button 22 move a first distance outward from the housing 1.

[0045] For example, when the user does not use the detection functions involving the first button 21 and the second button 22, it remains in the first state. Pressing the first button 21 and the second button 22 simultaneously triggers the second state. For example, it can be set through a circuit control that when the first button 21 and the second button 22 are pressed simultaneously, it triggers and changes to the second state.

[0046] Optionally, in the first state, at most one of the first button 21 and the second button 22 is in the pressed and triggered state. When the first button 21 or the second button 22 is pressed alone, the first state is maintained. For example, pressing the first button 21 or the second button 22 alone corresponds to different functions.

[0047] In the second state, both the first button 21 and the second button 22 are in the pressed and triggered state. Pressing the first button 21 and the second button 22 simultaneously triggers the second state, causing the first button 21 and the second button 22 to move a first distance outward from the housing 1, so as to protrude more in height from the outside of the housing 1, so that the detection function of this application can be realized by touching the first button 21 and the second button 22. This detection function can be set according to actual needs. For example, it is body fat detection, and the first button 21 and the second button 22 cooperate with other buttons on the wearable device to achieve it. These other buttons can be several buttons set at the positions where the wearable device contacts the user's skin.

[0048] In one embodiment, the limiting device includes a first limiting member 41 and a second limiting member 42;

[0049] When the wearable device is in the first state, the first limiting member 41 is disengaged from the first limiting portion 51 of the first button 21, and the second limiting member 42 is disengaged from the second limiting portion 52 of the second button 22;

[0050] When the wearable device is in the second state, the first limiting member 41 cooperates with the third limiting portion 71 of the first button 21, and the second limiting member 42 cooperates with the fourth limiting portion 72 of the second button 22.

[0051] In an embodiment of the present application, the first limiting member 41 cooperates with the first button 21 so that the first button 21 can be located at the first position and the third position. The second limiting member 42 cooperates with the second button 22 so that the second button 22 can be located at the second position and the fourth position.

[0052] The first limiting member 41 cooperates with the first limiting portion 51 to limit the first button 21 from moving outwardly of the housing 1. The second limiting member 42 cooperates with the second limiting portion 52 to limit the second button 22 from moving outwardly of the housing 1.

[0053] For example, the first limiting member 41 abuts against the side where the first limiting portion 51 moves outwardly of the housing 1 to limit the first button 21 from moving outwardly of the housing 1. The second limiting member 42 abuts against the side where the second limiting portion 52 moves outwardly of the housing 1 to limit the second button 22 from moving outwardly of the housing 1.

[0054] For example, after the first limiting member 41 is disengaged from the first limiting portion 51, the first button 21 is released from the blocking restriction of the first limiting member 41, and the first button 21 can move outwardly of the housing 1. The first limiting member 41 cooperates with the third limiting portion 71 so that the distance that the first button 21 moves outwardly of the housing 1 is the first distance, and the user can more easily access the first button 21. Similarly, after the second limiting member 42 is disengaged from the second limiting portion 52, the second button 22 can move outwardly of the housing 1. The second limiting member 42 cooperates with the fourth limiting portion 72 so that the distance that the second button 22 moves outwardly of the housing 1 is the first distance.

[0055] In one embodiment, as Figures 4 - 11 shown, the driving device further includes a driving device, and the driving device is disposed in the inner cavity 10.

[0056] The first limiting member 41 and the second limiting member 42 are located in the area between the first button 21 and the second button 22, and there is a second distance between the first limiting member 41 and the second limiting member 42. As Figure 4 , Figure 8 shown, it shows that there is a second distance between the first limiting member 41 and the second limiting member 42.

[0057] When the wearable device is in the first state, the first button 21 is in the first position, the second button 22 is in the second position, and the driving device is in the third state, so that the first limiting member 41 moves away from the first button 21, and the second limiting member 42 moves away from the second button 22, so that there is a third distance between the first limiting member 41 and the second limiting member 42. The limiting device disengages from the first limiting portion 51 of the first button 21 and the limiting device disengages from the second limiting portion 52 of the second button 22, so that the first button 21 and the second button 22 can move outward of the housing 1, and the third distance is less than the second distance. As Figure 6 , Figure 10 shown, it shows that there is a third distance between the first limiting member 41 and the second limiting member 42.

[0058] When the wearable device is in the second state, the first button 21 is in the third position, the second button 22 is in the fourth position, the first button 21 and the second button 22 move outward of the housing 1 by a first distance, and the driving device is in the fourth state, so that the first limiting member 41 moves toward the first button 21, and the second limiting member 42 moves toward the second button 22, so that there is the fourth distance between the first limiting member 41 and the second limiting member 42. The limiting device cooperates with the third limiting portion 71 of the first button 21 to limit the first button 21 from moving outward of the housing 1, and the limiting device cooperates with the fourth limiting portion 72 of the second button 22 to limit the second button 22 from moving outward of the housing 1. As Figure 7 , Figure 11 shown, it shows that there is a fourth distance between the first limiting member 41 and the second limiting member 42.

[0059] In the embodiments of the present application, the driving device is used to drive the first limiting member 41 and the second limiting member 42, so that the first limiting member 41 can cooperate with the first limiting portion 51 and the third limiting portion 71, and the second limiting member 42 can cooperate with the second limiting portion 52 and the fourth limiting portion 72.

[0060] In one embodiment, when the wearable device is in the first state, the first button 21 moves to the first position, and the second button 22 moves to the second position, so that the driving device is in the third state;

[0061] When the wearable device is in the second state, the first button 21 moves to the third position, and the second button 22 moves to the fourth position, so that the driving device is in the fourth state.

[0062] In one embodiment, as Figures 3 - 7 shown, the driving device includes a first bracket 12 and a first elastic member 11;

[0063] The first bracket 12 is disposed in the inner cavity 10. The first end of the first elastic member 11 is connected to the first limiting member 41, and the second end of the first elastic member 11 is connected to the second limiting member 42;

[0064] A first portion of the first bracket 12 is located between the first limiting member 41 and the second limiting member 42, so that the first elastic member 11 is in a first deformed state, and a second distance exists between the first limiting member 41 and the second limiting member 42;

[0065] The driving device being in the third state includes the first bracket 12 disengaging from the first limiting member 41 and the first bracket 12 disengaging from the second limiting member 42, and the first elastic member 11 being in an original state;

[0066] The driving device being in the fourth state includes a second portion of the first bracket 12 being located between the first limiting member 41 and the second limiting member 42, and the first elastic member 11 being in a second deformed state;

[0067] When the wearable device is in the first state, the first button 21 moves to the first position, and the second button 22 moves to the second position, so that the first bracket 12 disengages from the first limiting member 41 and the first bracket 12 disengages from the second limiting member 42, and the first elastic member 11 is in an original state;

[0068] When the wearable device is in the second state, the first button 21 moves to the third position, and the second button 22 moves to the fourth position, so that a second portion of the first bracket 12 is located between the first limiting member 41 and the second limiting member 42, and the first elastic member 11 is in a second deformed state.

[0069] In an embodiment of the present application, when the wearable device is in the original state, a first portion of the first bracket 12 forms a support between the first limiting member 41 and the second limiting member 42, so that a second distance exists between the first limiting member 41 and the second limiting member 42, and the first elastic member 11 is in a first deformed state. The first deformed state is a state in which the first elastic member 11 is stretched.

[0070] During the process of the first part of the first bracket 12 detaching from between the first limiting member 41 and the second limiting member 42, the self-elasticity of the first elastic member 11 acts on the first limiting member 41 and the second limiting member 42, pulling the first limiting member 41 and the second limiting member 42 closer. After the first part detaches from the position between the first limiting member 41 and the second limiting member 42, there is a third distance between the first limiting member 41 and the second limiting member 42, and the first elastic member 11 returns to its original state. For example, the first elastic member 11 is a spring, and the original state of the spring is the original length state. The first elastic member 11 can also be a structure such as a spring piece.

[0071] After the first button 21 moves to the third position and the second button 22 moves to the fourth position, the second part of the first bracket 12 enters between the first limiting member 41 and the second limiting member 42. The second part forms a support for the first limiting member 41 and the second limiting member 42, so that the first limiting member 41 and the second limiting member 42 move away to have a fourth distance. The first elastic member 11 is stretched compared to its original state.

[0072] In an embodiment of the present application, as Figures 4 - 7 shown, the first bracket 12 includes a convex structure 123 and two arms. For example, the arms include a first arm 121 and a second arm 122. The first bracket 12 can be an integral structure.

[0073] The first part of the convex structure 123 is located between the first limiting member 41 and the second limiting member 42, so that there is the second distance between the first limiting member 41 and the second limiting member 42;

[0074] When the wearable device is in the first state, the first button 21 abuts against one of the arms, and the second button 22 abuts against the other arm, so that the convex structure 123 detaches from the first limiting member 41 and the convex structure 123 detaches from the second limiting member 42, and the first elastic member 11 is in its original state;

[0075] When the wearable device is in the second state, the first button 21 detaches from one of the arms, and the second button 22 detaches from the other arm, so that the second part of the convex structure 123 is located between the first limiting member 41 and the second limiting member 42, and the first elastic member 11 is in the second deformed state.

[0076] In an embodiment of the present application, the convex structure 123 is used to form a support between the first limiting member 41 and the second limiting member 42. The first part of the convex structure 123 is the first part of the first bracket 12. The second part of the convex structure 123 is the second part of the first bracket 12.

[0077] For example, when the first portion of the protruding structure 123 forms a support between the first limiting member 41 and the second limiting member 42 , the first limiting member 41 can cooperate with the first limiting portion 51 , and the second limiting member 42 can cooperate with the second limiting portion 52 .

[0078] The protruding structure 123 forms a support between the first limiting member 41 and the second limiting member 42 , so that the first limiting member 41 can be matched with the first limiting portion 51 , and the second limiting member 42 can be matched with the second limiting portion 52 .

[0079] like Figure 5 In the embodiment, the middle of the protruding structure 123 is protruding, and the two sides are concave, so that the protruding structure 123 can more easily enter the position between the first limiting member 41 and the second limiting member 42. For example, the top of the protruding structure 123 has an arc-shaped edge to play a guiding role between the first limiting member 41 and the second limiting member 42.

[0080] For example, of the two arms, the first arm 121 and the second arm 122 extend to both sides from the protruding structure 123, so that the first arm 121 is located on the path of the first button 21 moving inward when pressed, and the second arm 122 is located on the path of the second button 22 moving inward when pressed.

[0081] For example, Figure 5 The middle is a state where one side of the first button 21 is pressed. When the first button 21 or the second button 22 is pressed alone, the protruding structure 123 of the first bracket 12 will not be separated from the position between the first limiting member 41 and the second limiting member 42. The support arm can provide a supporting and squeezing structure for the first button 21 and the second button 22.

[0082] In one embodiment, Figures 4 - 7 As shown, a waist-shaped hole 120 is opened in the middle area of the first bracket 12, and a rotating shaft 15 is provided in the housing 1, and the rotating shaft 15 is passed through the waist-shaped hole 120;

[0083] When the wearable device is in the first state, Figure 6 As shown, the first button 21 moves to the first position, and the second button 22 moves to the second position, so as to drive the first bracket 12 to move along the long diameter direction of the waist-shaped hole 120, so that the rotating shaft 15 is located at the fifth position in the waist-shaped hole 120;

[0084] When the wearable device is in the second state, Figure 7 As shown, the first button 21 is located at the third position, and the second button 22 is located at the fourth position, so as to drive the first bracket 12 to move along the long diameter direction of the waist-shaped hole 120 so that the rotating shaft 15 is located at the sixth position in the waist-shaped hole 120.

[0085] In this embodiment, the waist-shaped hole 120 cooperates with the rotating shaft 15 to provide guiding and limiting effects for the movement of the first bracket 12.

[0086] For example, the major axis direction of the waist-shaped hole 120 is the same as the movement direction of the first bracket 12.

[0087] When the first bracket 12 is simultaneously squeezed by the first button 21 and the second button 22, the first bracket 12 needs to move inward. The major axis direction of the waist-shaped hole 120 is the same as this movement direction, enabling the first bracket 12 to move relative to the rotating shaft 15.

[0088] When the first bracket 12 is squeezed on one side, the rotating shaft 15 positions the first bracket 12, causing the first bracket 12 to rotate around the rotating shaft 15 as the center. For example, when only the first button 21 is pressed, the first button 21 squeezes the arm of the first bracket 12 to drive the first bracket 12 to rotate around the rotating shaft 15 as the center.

[0089] For example, the waist-shaped hole 120 is provided on the convex structure 123.

[0090] In one embodiment, the driving device further includes a second elastic member 13, and the second elastic member 13 is disposed on a side of the first bracket 12 away from the first elastic member 11;

[0091] When the wearable device is in the first state, the first button 21 moves to the first position, and the second button 22 moves to the second position, so that the first bracket 12 disengages from the first limiting member 41 and the first bracket 12 disengages from the second limiting member 42, and the first bracket 12 abuts against the second elastic member 13, so that the second elastic member 13 is in the third deformed state;

[0092] When the wearable device is in the second state, the first button 21 moves to the third position, the second button 22 moves to the fourth position, and the second elastic member 13 is in the second original state, so that the second part of the first bracket 12 is located between the first limiting member 41 and the second limiting member 42.

[0093] In the embodiment of the present application, the second elastic member 13 is disposed in the inner cavity 10. For example, the second elastic member 13 is disposed on the inner wall of the inner cavity 10. The second elastic member 13 can be a delayed elastic member. After being affected by compression, the delayed elastic member can maintain the compressed state and return to its original state after a certain period of time. The second elastic member 13 can be an elastic structure such as rubber or foam.

[0094] When the first part of the first bracket 12 is located between the first limiting member 41 and the second limiting member 42, the second elastic member 13 maintains the original state.

[0095] When the wearable device is in the first state, pressing the first button 21 and the second button 22 simultaneously squeezes the first bracket 12, causing a first part of the first bracket 12 to move out of the position between the first limiting member 41 and the second limiting member 42. The first bracket 12 is squeezed toward the side where the second elastic member 13 is located, so that the second elastic member 13 is compressed.

[0096] When the wearable device is in the second state, the second elastic member 13 returns to its original state and pushes the first bracket 12 to move. A second part of the first bracket 12 moves between the first limiting member 41 and the second limiting member 42 and pushes the first limiting member 41 and the second limiting member 42 away from each other, so that there is a fourth distance between the first limiting member 41 and the second limiting member 42. The time for the second elastic member 13 to return to its original state is greater than the time taken for the wearable device to switch from the first state to the second state.

[0097] Optionally, after the wearable device is in the second state, pressing the first button 21 and the second button 22 again causes the first limiting member 41 to cooperate with the first limiting portion 51 and the second limiting member 42 to cooperate with the second limiting portion 52, so that the wearable device returns to its original state.

[0098] Optionally, the convex structure 123 is a gradient structure. The side of the gradient structure facing the second elastic member 13 is the side with a larger size. For example, the gradient structure has an arc-shaped edge.

[0099] For example, when pressing the first button 21 or the second button 22 alone, the first part of the convex structure 123 cannot be driven to move out of the position between the first limiting member 41 and the second limiting member 42. The first bracket 12 is tilted toward the pressed side with the second elastic member 13 as a support, and the convex structure 123 remains between the first limiting member 41 and the second limiting member 42 to form a support.

[0100] For example, a delay elastic member supports the convex structure 123, and the first arm 121 and the second arm 122 form a seesaw structure on both sides of the convex structure 123.

[0101] In an embodiment of the present application, as Figures 8 - 11 shown, the driving device includes an electromagnetic relay 17, and the first limiting member 41 and the second limiting member 42 are magnetic members;

[0102] A part of the structure of the electromagnetic relay 17 is located between the first limiting member 41 and the second limiting member 42. The electromagnetic relay 17 repels the first limiting member 41 in terms of polarity, and the electromagnetic relay 17 repels the second limiting member 42 in terms of polarity, so that there is the second distance between the first limiting member 41 and the second limiting member 42.

[0103] The driving device being in the third state includes the electromagnetic relay 17 being attracted to the first limiting member 41 in terms of polarity and the electromagnetic relay 17 being attracted to the second limiting member 42 in terms of polarity;

[0104] The driving device being in the fourth state includes the electromagnetic relay 17 being repelled by the first limiting member 41 in terms of polarity and the electromagnetic relay 17 being repelled by the second limiting member 42 in terms of polarity;

[0105] When the wearable device is in the first state, the first button 21 moves to the first position and the second button 22 moves to the second position, so that the electromagnetic relay 17 is attracted to the first limiting member 41 in terms of polarity and the electromagnetic relay 17 is attracted to the second limiting member 42 in terms of polarity, so that there is a third distance between the first limiting member 41 and the second limiting member 42.

[0106] When the wearable device is in the second state, the first button 21 moves to the third position and the second button 22 moves to the fourth position, so that the electromagnetic relay 17 is repelled by the first limiting member 41 in terms of polarity and the electromagnetic relay 17 is repelled by the second limiting member 42 in terms of polarity, so that there is a fourth distance between the first limiting member 41 and the second limiting member 42.

[0107] In the embodiments of the present application, by changing the magnetic field generated by the electromagnetic relay 17 to form an adsorption or repulsion effect with the magnetic member, the first limiting member 41 and the second limiting member 42 are moved. In this way, the cooperation relationship between the first limiting member 41 and the first limiting portion 51, and the cooperation relationship between the first limiting member 41 and the third limiting portion 71 can be effectively operated. The cooperation relationship between the second limiting member 42 and the second limiting portion 52, and the cooperation relationship between the second limiting member 42 and the fourth limiting portion 72 can also be effectively operated.

[0108] For example, by changing the current direction of the electromagnetic relay 17 and changing the electrodes on both sides of the electromagnetic relay 17, the cooperation relationship between the electromagnetic relay 17 and the first limiting member 41 and the second limiting member 42 is changed.

[0109] In one embodiment, as Figures 8 - 11 shown, the driving device includes an electromagnetic relay 17 and a third elastic member 18;

[0110] A part of the structure of the electromagnetic relay 17 is located between the first limiting member 41 and the second limiting member 42, the third elastic member 18 is connected to the first limiting member 41 and the second limiting member 42, and the third elastic member 18 is in an original state, so that there is a second distance between the first limiting member 41 and the second limiting member 42;

[0111] When the driving device is in the third state, it includes that the electromagnetic relay 17 and the first limiting member 41 attract each other in polarity, and the electromagnetic relay 17 and the second limiting member 42 attract each other in polarity. The third elastic member 18 is in the fourth deformation state. In this state, there is a third distance between the first limiting member 41 and the second limiting member 42, and the first limiting member 41 and the second limiting member 42 compress the third elastic member 18.

[0112] When the driving device is in the fourth state, it includes that the electromagnetic relay 17 is in a power-off state, and the third elastic member 18 is in the fifth deformation state. When the electromagnetic relay 17 is powered off, it cannot form an adsorption effect on the first limiting member 41 and the second limiting member 42. The compressed third elastic member 18 extends to push the first limiting member 41 and the second limiting member, so that there is a fourth distance between the first limiting member 41 and the second limiting member 42.

[0113] When the wearable device is in the first state, the first button 21 moves to the first position, and the second button 22 moves to the second position, so that the electromagnetic relay 17 is in a powered-on state, the electromagnetic relay 17 and the first limiting member 41 attract each other in polarity, the electromagnetic relay 17 and the second limiting member 42 attract each other in polarity, and the third elastic member 18 is in the fourth deformation state;

[0114] When the wearable device is in the second state, the first button 21 moves to the third position, the second button 22 moves to the fourth position, the electromagnetic relay 17 is in a power-off state, and the third elastic member 18 is in the fifth deformation state.

[0115] In the embodiment of the present application, when the wearable device is in the original state, the electromagnetic relay 17 is powered off, and the third elastic member 18 is in the original state, maintaining a second distance between the first limiting member 41 and the second limiting member 42.

[0116] The first button 21 moves to the first position, and the second button 22 moves to the second position, making the electromagnetic relay 17 powered on and magnetized, so that it can adsorb the first limiting member 41 and the second limiting member 42, compressing the third elastic member 18. Thus, the wearable device maintains the first state.

[0117] The first button 21 moves to the third position, and the second button 22 moves to the fourth position, making the electromagnetic relay 17 powered off, unable to adsorb the first limiting member 41 and the second limiting member 42. The third elastic member 18 extends to push the first limiting member 41 to cooperate with the third limiting portion 71, and the second limiting member 42 to cooperate with the fourth limiting portion 72. Thus, the wearable device maintains the second state.

[0118] Optionally, after a preset time period after the wearable device is in the first state, the electromagnetic relay 17 automatically cuts off the power, so that the wearable device automatically switches to the second state.

[0119] After the wearable device is in the second state, press the first button 21 and the second button 22 simultaneously, so that the third elastic member 18 pushes the first limiting member 41 to cooperate with the first limiting portion 51, and the third elastic member 18 pushes the second limiting member 42 to cooperate with the second limiting portion 52.

[0120] In an embodiment of the present application, as Figure 6 shown, the housing 1 is provided with a first guiding groove 161 and a second guiding groove 162. The first limiting member 41 is located in the first guiding groove 161, and the second limiting member 42 is located in the second guiding groove 162.

[0121] The first guiding groove 161 provides a path limit for the movement of the first limiting member 41, and the second guiding groove 162 provides a path limit for the movement of the second limiting member 42. This makes the cooperation between the first limiting member 41 and the first limiting portion 51 more precise, and the cooperation between the second limiting member 42 and the second limiting portion 52 more precise, ensuring the accuracy of the switching between the first state and the second state of the first limiting member 41 and the second limiting member 42.

[0122] In an embodiment of the present application, as Figures 4 - 11 shown, the first limiting portion 51 is a first groove structure, and the second limiting portion 52 is a second groove structure. When the wearable device is in the first state, the first limiting member 41 abuts against the side wall of the first groove structure, and the second limiting member 42 abuts against the side wall of the second groove structure.

[0123] The third limiting portion 71 is a first convex structure, and the fourth limiting portion 72 is a second convex structure. When the wearable device is in the second state, the first limiting member 41 abuts against the first convex structure, and the second limiting member 42 abuts against the second convex structure.

[0124] The first groove structure and the second groove structure can be the same groove structure. The groove structure is simple in molding and convenient for production and processing. And the groove structure is easier to form a cooperation with the limiting member to limit the movement of the button.

[0125] Taking the first button 21 as an example, the first groove structure cooperates with the first limiting member 41. In the first state, the first limiting member 41 extends into the first groove structure. The first limiting member 41 abuts against the inner wall of the first groove structure facing away from the outer side of the first button 21 to limit the outward movement of the first button 21.

[0126] The first convex structure and the second convex structure can adopt the same convex structure, which is simple to form and convenient for production and processing.

[0127] In an embodiment of the present application, the housing 1 is further provided with a first button hole 31 and a second button hole 32. A fourth elastic member 61 is disposed in the first button hole 31, and a fifth elastic member 62 is disposed in the second button hole 32. The fourth elastic member 61 abuts against the first button 21, and the fifth elastic member 62 abuts against the second button 22.

[0128] When the wearable device is in the first state, both the fourth elastic member 61 and the fifth elastic member 62 are in a compressed state.

[0129] When the wearable device is in the second state, both the fourth elastic member 61 and the fifth elastic member 62 are extended, so that the first button 21 and the second button 22 can move a first distance outward from the housing 1.

[0130] During the process of the wearable device switching from the first state to the second state, the fourth elastic member 61 pushes the first button 21 to move a first distance outward from the housing 1, and the first limiting member 41 and the third limiting portion 71 cooperate to limit the first button 21 from moving further outward. The fifth elastic member 62 pushes the second button 22 to move a first distance outward from the housing 1, and the second limiting member 42 and the fourth limiting portion 72 cooperate to limit the second button 22 from moving further outward.

[0131] For example, the button has a head and a stem, and the size of the head is larger than that of the stem. The fourth elastic member 61 is sleeved on the stem of the first button 21 and abuts against the head, and the fifth elastic member 62 is sleeved on the stem of the second button 22 and abuts against the head.

[0132] Taking the first button 21 as an example, in the first state, the head presses the fourth elastic member 61 to be compressed. In the second state, the compressed fourth elastic member 61 extends to support the first button 21 to move outward. The first distance of movement can be set according to the actual required size of the first button 21. The second button 22 adopts the same structural solution as the first button 21.

[0133] For example, both the first button hole 31 and the second button hole 32 are countersunk holes, and the fourth elastic member 61 and the fifth elastic member 62 are disposed on the steps of the countersunk holes so that the head can extend into the countersunk hole.

[0134] The fourth elastic member 61 and the fifth elastic member 62 can be elastic telescopic structures, such as springs, elastic sheets and other structures.

[0135] Optionally, the third limiting part 71 and the fourth limiting part 72 may be protrusions protruding from the rod part. For example, when the first button 21 and the second button 22 move outward. When the protrusion on the first button 21 moves to the first limiting member 41 to form a stop, and the protrusion on the second button 22 moves to the second limiting member 42 to form a stop, at this time, the first button 21 and the second button 22 move a first distance.

[0136] In an embodiment of the present application, as Figures 4 - 8 shown, the wearable device further includes:

[0137] A first trigger switch 91, the first trigger switch 91 is arranged in the inner cavity 10;

[0138] A second trigger switch 92, the second trigger switch 92 is arranged in the inner cavity 10;

[0139] When the first button 21 is in the first position and the second button 22 is in the original position, the first limiting member 41 cooperates with the first limiting part 51, the second limiting member 42 cooperates with the second limiting part 52, the first button 21 abuts against the first bracket 12, and the first bracket 12 rotates around the rotating shaft 15 to abut against the first trigger switch 91, and the first trigger switch 91 is in a triggered state.

[0140] When the second button 22 is in the second position and the first button 21 is in the original position, the second limiting member 42 cooperates with the second limiting part 52, the second limiting member 42 cooperates with the second limiting part 52, the second button 22 abuts against the first bracket 12, and the first bracket 12 rotates around the rotating shaft 15 to abut against the second trigger switch 92, and the second trigger switch 92 is in a triggered state.

[0141] When the first trigger switch 91 and the second trigger switch 92 are triggered separately, the wearable device responds with different functions from being triggered simultaneously.

[0142] For example, in an embodiment where the first button 21 and the second button 22 are simultaneously pressed to squeeze the first bracket 12. One of the first trigger switch 91 and the second trigger switch 92 will be squeezed by the two arms of the first bracket 12 respectively, so that both the first trigger switch 91 and the second trigger switch 92 are triggered. When pressed separately, the pressed arm will trigger the corresponding one of the first trigger switch 91 and the second trigger switch 92. As Figure 5 shown, the first button 21 presses down the first arm 121 to trigger the first trigger switch 91.

[0143] The rotating shaft 15 serves as the support shaft for the rotation of the first bracket 12, facilitating the rotation of the first bracket 12 when pressing one of the first button 21 and the second button 22 and triggering the corresponding trigger switch.

[0144] For example, when the first button 21 is pressed alone, the first limiting member 41 is located within the first groove structure, so that the first limiting member 41 remains in cooperation with the first limiting portion 51. When the second button 22 is pressed alone, the second limiting member 42 is located within the second groove structure, so that the second limiting member 42 remains in cooperation with the second limiting portion 52.

[0145] In one embodiment, as Figures 4 - 11 shown, the wearable device further includes:

[0146] A first trigger switch 91, which is provided in the inner cavity 10;

[0147] A second trigger switch 92, which is provided in the inner cavity 10;

[0148] In the case where the first button 21 is in the first position and the second button 22 is in the original position, the limiting device cooperates with the first limiting portion 51, the limiting device cooperates with the second limiting portion 52, and the first trigger switch 91 is in the triggered state;

[0149] In the case where the second button 22 is in the second position and the first button 21 is in the original position, the limiting device cooperates with the first limiting portion 51, the limiting device cooperates with the second limiting portion 52, and the second trigger switch 92 is in the triggered state.

[0150] In the embodiments of the present application, pressing the first button 21 alone can trigger the first trigger switch 91. Pressing the second button 22 alone can trigger the second trigger switch 92 alone.

[0151] Optionally, in the embodiment where pressing the first button 21 and the second button 22 simultaneously can trigger the electromagnetic relay 17 to be energized to adsorb with the first limiting member 41 and the second limiting member 42. Pressing the first button 21 alone will trigger the first trigger switch 91, and pressing the second button 22 alone will trigger the second trigger switch 92.

[0152] In one embodiment of the present application, as Figures 4 - 11 shown, the wearable device further includes a second bracket 14, the second bracket 14 is provided in the inner cavity 10, and the first trigger switch 91 and the second trigger switch 92 are provided on the second bracket 14.

[0153] The second bracket 14 provides support to set the first trigger switch 91 and the second trigger switch 92, facilitating the cooperation of each structure.

[0154] For example, the second elastic member 13 is provided on the second bracket 14, and the second bracket 14 supports the second elastic member 13.
