Wearing equipment according to an embodiment of the present application is described below with reference to fig. 1 to 11.

As shown in fig. 1-11, a wearable device according to some embodiments of the present application, the wearable device comprising:

the key comprises a shell 1, wherein the shell 1 is provided with an inner cavity 10, and the shell 1 is provided with a first key hole 31 and a second key hole 32 which are communicated with the inner cavity 10;

the first key 21, the said first key 21 locates the said first key hole 31;

the second key 22, the said second key 22 locates the said second key hole 32;

the limiting device is arranged in the inner cavity 10, the limiting device is matched with the first limiting part 51 of the first key 21 to limit the first key 21 to move towards the outer side of the shell 1, and the limiting device is matched with the second limiting part 52 of the second key 22 to limit the second key 22 to move towards the outer side of the shell 1. The limiting device is matched with the first limiting part 51 and the second limiting part 52 to limit the state that the first key 21 and the second key 22 move towards the outer side of the shell 1 to be the original state of the wearable device.

Under the condition that the wearable device is in a first state, the first key 21 is in a first position, the second key 22 is in a second position, the limiting device is separated from the first limiting part 51 of the first key 21, and the limiting device is separated from the second limiting part 52 of the second key 22, so that the first key 21 and the second key 22 can move towards the outer side of the shell 1;

under the condition that the wearable device is in the second state, the first button 21 and the second button 22 move to the outer side of the housing 1 by a first distance, the first button 21 is in the third position, the second button 22 is in the fourth position, the limiting device is matched with the third limiting portion 71 of the first button 21 to limit the first button 21 to move to the outer side of the housing 1, and the limiting device is matched with the fourth limiting portion 72 of the second button 22 to limit the second button 22 to move to the outer side of the housing 1. As shown in fig. 7, the first button 21 and the second button 22 are moved outward of the housing 1 by a first distance.

In the embodiment of the application, under the condition that the wearable device is in the second state, the first key 21 and the second key 22 can move a first distance to the outer side of the housing 1, and the height dimension of the first key 21 and the second key 22 protruding out of the housing 1 is increased, so that the first key 21 and the second key 22 can be touched for relevant detection, the housing 1 is prevented from being touched by fingers, and the detection accuracy is improved.

In the wearing equipment of this application, be used for triggering health detection to the user through setting up a plurality of buttons. The health test may be body fat test, blood pressure test, etc. The detection function is realized, for example, by the user touching the first key 21 and the second key 22.

The position of the first key 21 and the position of the second key 22 are limited through the limiting device. For example, the position limiting device may be a control device which is connected with each other and can control the movement of the first key 21 and the second key 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 a transmission manner. For example, in the first state, the control device controls the first button 21 to be maintained at the first position and the second button 22 to be maintained at the second position. In the second state, the control device controls the first button 21 to be kept at the third position and the second button 22 to be kept at the fourth position. Compared with the first position, the first key 21 and the second key 22 protrude out of the housing 1 in the second state, so that when the wearable device is switched from the first state to the second state, the first key 21 and the second key 22 move a first distance to the outside of the housing 1.

For example, when the user does not use the detection function in which the first key 21 and the second key 22 participate, the state is maintained in the first state. The second state is triggered by the simultaneous pressing of the first key 21 and the second key 22. For example, the change to the second state may be triggered by the setting circuit control in the case where the first key 21 and the second key 22 are simultaneously pressed.

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

The second state is a state in which both the first key 21 and the second key 22 are pressed and triggered. The first key 21 and the second key 22 are triggered to be in the second state under the condition that the first key 21 and the second key 22 are pressed simultaneously, the first key 21 and the second key 22 move for a first distance to the outer side of the shell 1, and therefore more heights protrude to the outer side of the shell 1, and the detection function of the application can be achieved by touching the first key 21 and the second key 22. The detection function can be set according to actual requirements. For example, body fat detection, the first button 21 and the second button 22 are implemented in cooperation with other buttons on the wearable device. The other keys may be a number of keys arranged at a position where the wearable device is in contact with the skin of the user.

In one embodiment, the limiting device includes a first limiting member 41, a second limiting member 42;

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;

under the condition that the wearable device is in the second state, the first limiting member 41 is engaged with the third limiting portion 71 of the first button 21, and the second limiting member 42 is engaged with the fourth limiting portion 72 of the second button 22.

In the embodiment of the present application, the first position-limiting member 41 is matched with the first key 21, so that the first key 21 can be located at the first position and the third position. The second position-limiting element 42 is engaged with the second button 22, so that the second button 22 can be located at the second position and the fourth position.

The first stopper 41 is engaged with the first stopper portion 51, and can restrict the first push button 21 from moving to the outside of the housing 1. The second stopper 42 is engaged with the second stopper portion 52, and can restrict the second push button 22 from moving to the outside of the housing 1.

For example, the first stopper 41 abuts against a side of the first stopper portion 51 in the direction of moving toward the outside of the housing 1, so that the first push button 21 can be restricted from moving toward the outside of the housing 1. The second stopper 42 abuts against one side of the second stopper portion 52 in the direction of moving toward the outside of the housing 1, so as to restrict the second button 22 from moving toward the outside of the housing 1.

For example, after the first limiting member 41 is separated from the first limiting portion 51, the first key 21 is separated from the blocking limitation of the first limiting member 41, the first key 21 can move to the outside of the housing 1, and the first limiting member 41 is engaged with the third limiting portion 71, so that the distance that the first key 21 moves to the outside of the housing 1 is the first distance, and the user can more easily contact the first key 21. Similarly, after the second limiting member 42 is separated from the second limiting portion 52, the second button 22 can move toward the outside of the housing 1, and the second limiting member 42 is engaged with the fourth limiting portion 72, so that the distance that the second button 22 moves toward the outside of the housing 1 is the first distance.

In one embodiment, as shown in fig. 4-11, the driving means further comprises a driving means, which is provided in the inner cavity 10.

The first limiting member 41 and the second limiting member 42 are located in an area between the first key 21 and the second key 22, and a second distance is formed between the first limiting member 41 and the second limiting member 42. As shown in fig. 4 and 8, a second distance is formed between the first limiting member 41 and the second limiting member 42.

Under the condition that the wearable device is in the first state, the first key 21 is in the first position, the second key 22 is in the second position, and the driving device is in the third state, so that the first limiting member 41 moves in a direction away from the first key 21, the second limiting member 42 moves in a direction away from the second key 22, so that a third distance is formed between the first limiting member 41 and the second limiting member 42, the limiting device is disengaged from the first limiting portion 51 of the first key 21, and the limiting device is disengaged from the second limiting portion 52 of the second key 22, so that the first key 21 and the second key 22 can move towards the outer side of the housing 1, and the third distance is smaller than the second distance. As shown in fig. 6 and 10, a third distance is formed between the first limiting member 41 and the second limiting member 42.

In the case where the wearable device is in the second state, the first button 21 is in the third position, the second button 22 is in a fourth position, the first button 21 and the second button 22 move to the outside of the housing 1 by a first distance, the driving device is in a fourth state, so that the first position-limiting member 41 moves toward the first button 21, the second position-limiting member 42 moves toward the second button 22, so that the first limiting member 41 and the second limiting member 42 have the fourth distance therebetween, the limiting device cooperates with the third limiting portion 71 of the first key 21 to limit the first key 21 from moving to the outside of the housing 1, the limiting device is matched with the fourth limiting part 72 of the second key 22 to limit the second key 22 to move towards the outer side of the shell 1. As shown in fig. 7 and 11, a fourth distance is formed between the first limiting member 41 and the second limiting member 42.

In the embodiment of the present application, the driving device is configured to drive 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 third limiting portion 71, and the second limiting member 42 can be matched with the second limiting portion 52 and the fourth limiting portion 72.

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

when the wearable device is in the second state, the first button 21 is moved to the third position, and the second button 22 is moved to the fourth position, so that the driving device is in the fourth state.

In one embodiment, as shown in fig. 3-7, the driving means comprises a first bracket 12 and a first elastic member 11;

the first bracket 12 is disposed in the inner cavity 10, a first end of the first elastic element 11 is connected to the first limiting element 41, and a second end of the first elastic element 11 is connected to the second limiting element 42;

the 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 deformation state, and the first limiting member 41 and the second limiting member 42 have the second distance therebetween;

the driving device in the third state includes that the first bracket 12 is disengaged from the first limiting member 41, the first bracket 12 is disengaged from the second limiting member 42, and the first elastic member 11 is in the original state;

the driving device being in the fourth state includes the 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 the second deformation state;

under the condition that the wearable device is in the first state, the first button 21 moves to the first position, the second button 22 moves to the second position, so that the first bracket 12 is separated from the first limiting part 41, the first bracket 12 is separated from the second limiting part 42, and the first elastic part 11 is in the original state;

under the condition that 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 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 the second deformation state.

In the embodiment of the application, under the condition that the wearable device is in the original state, the first portion of the first bracket 12 forms a support between the first limiting member 41 and the second limiting member 42, so that the first limiting member 41 and the second limiting member 42 have a second distance therebetween, and the first elastic member 11 is in the first deformation state. The first deformation state is a state in which the first elastic member 11 is stretched.

In the process of separating the first portion of the first bracket 12 from the first retaining member 41 and the second retaining member 42. The elasticity of the first elastic member 11 acts on the first limiting member 41 and the second limiting member 42, and pulls the first limiting member 41 and the second limiting member 42 to approach each other. After the first portion is separated from the position between the first limiting member 41 and the second limiting member 42, a third distance is formed between the first limiting member 41 and the second limiting member 42, and the first elastic member 11 is restored to the original state. For example, the first elastic member 11 is a spring, and the original state of the spring is the original state. The first elastic element 11 may also be a spring sheet or the like.

After the first button 21 moves to the third position and the second button 22 moves to the fourth position, the second portion of the first bracket 12 enters between the first limiting member 41 and the second limiting member 42. The second portion supports the first limiting member 41 and the second limiting member 42, so that the first limiting member 41 and the second limiting member 42 are away from each other to have a fourth distance. The first elastic member 11 is stretched as compared to the original state.

In one embodiment of the present application, as shown in fig. 4-7, the first bracket 12 includes a projection structure 123 and two arms. For example, the support arms include a first support arm 121 and a second support arm 122. The first bracket 12 may be a unitary structure.

The first portion of the protrusion 123 is located between the first position-limiting member 41 and the second position-limiting member 42, so that the first position-limiting member 41 and the second position-limiting member 42 have the second distance therebetween;

under the condition that the wearable device is in the first state, the first button 21 abuts one of the arms, the second button 22 abuts the other of the arms, so that the protruding structure 123 is disengaged from the first limiting member 41, the protruding structure 123 is disengaged from the second limiting member 42, and the first elastic member 11 is in the original state;

under the condition that the wearable device is in the second state, the first button 21 is disengaged from one of the arms, and the second button 22 is disengaged from the other arm, so that the second portion of the protrusion 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 deformation state.

In the embodiment of the present application, the protrusion 123 is used to form a support between the first limiting member 41 and the second limiting member 42. A first portion of the projection arrangement 123 is a first portion of the first leg 12. A second portion of the projection arrangement 123 is a second portion of the first leg 12.

For example, when the first portion of the protrusion 123 forms a support between the first limiting member 41 and the second limiting member 42, the first limiting member 41 can be engaged with the first limiting portion 51, and the second limiting member 42 can be engaged with the second limiting portion 52.

The protrusion 123 forms a support between the first limiting member 41 and the second limiting member 42, so that the first limiting member 41 is engaged with the first limiting portion 51, and the second limiting member 42 is engaged with the second limiting portion 52.

As shown in fig. 5, the middle portion of the protrusion 123 is protruded, and both sides are recessed, so that the protrusion 123 can more easily enter the position between the first position-limiting member 41 and the second position-limiting member 42. For example, the top of the protrusion 123 has an arc edge to play a guiding role between the first limiting member 41 and the second limiting member 42.

For example, in two arms, the first arm 121 and the second arm 122 extend from the protrusion 123 to two sides, such that the first arm 121 is located on the inward moving path of the first button 21 pressed, and the second arm 122 is located on the inward moving path of the second button 22 pressed.

For example, fig. 5 shows a state where the first button 21 side is pressed. When the first button 21 or the second button 22 is pressed alone, the protrusion 123 of the first bracket 12 does not depart from the position between the first position-limiting member 41 and the second position-limiting member 42. The arm can provide a structure for supporting the pressing for the first button 21 and the second button 22.

In one embodiment, as shown in fig. 4 to 7, a waist-shaped hole 120 is formed in a middle region of the first support 12, a rotating shaft 15 is disposed in the housing 1, and the rotating shaft 15 is disposed in the waist-shaped hole 120;

when the wearable device is in the first state, as shown in fig. 6, 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;

when the wearable device is in the second state, as shown in fig. 7, 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.

In this embodiment, the kidney-shaped hole 120 cooperates with the shaft 15 to provide a guiding and limiting effect for the movement of the first bracket 12.

For example, the longitudinal direction of the kidney-shaped hole 120 is the same as the moving direction of the first carriage 12.

When the first carriage 12 is pressed by the first button 21 and the second button 22 at the same time, the first carriage 12 needs to move inward. The longitudinal direction of the kidney hole 120 is the same as the moving direction, and the first bracket 12 is movable relative to the rotating shaft 15.

When one side of the first bracket 12 is pressed, the rotating shaft 15 has a positioning effect on the first bracket 12, so that the first bracket 12 rotates around the rotating shaft 15. For example, when only the first button 21 is pressed, the first button 21 presses the arm of the first frame 12 to rotate the first frame 12 about the rotation axis 15.

For example, a kidney-shaped hole 120 is provided on the protrusion structure 123.

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;

under the condition that the wearable device is in the first state, the first button 21 moves to the first position, the second button 22 moves to the second position, so that the first bracket 12 is separated from the first limiting part 41, the first bracket 12 is separated from the second limiting part 42, and the first bracket 12 is abutted against the second elastic part 13, so that the second elastic part 13 is in the third deformation state;

under the condition that 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 portion of the first bracket 12 is located between the first limiting member 41 and the second limiting member 42.

In the embodiment of the present application, the second elastic element 13 is disposed in the inner cavity 10. For example, the second elastic member 13 is provided on the inner wall of the inner cavity 10. The second elastic member 13 may be a delay elastic member that can maintain a compressed state and restore its original state after a certain period of time after being affected by compression. The second elastic member 13 may be an elastic structure such as rubber, foam, or the like.

In the case that the first portion 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.

When the wearable device is in the first state, the first key 21 and the second key 22 are pressed simultaneously to press the first bracket 12, so that the first portion of the first bracket 12 moves out of the position between the first limiting piece 41 and the second limiting piece 42, and the first bracket 12 presses the side where the second elastic piece 13 is located, so that the second elastic piece 13 is compressed.

When the wearable device is in the second state, the second elastic element 13 restores the original state and pushes the first support 12 to move. The second portion of the first bracket 12 moves to 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 a fourth distance is formed between the first limiting member 41 and the second limiting member 42. The time for the second elastic member 13 to return to the original state is longer than the time for the wearable device to switch from the first state to the second state.

Optionally, after the wearable device is in the second state, the first key 21 and the second key 22 are pressed again, so that the first limiting member 41 is engaged with the first limiting portion 51, and the second limiting member 42 is engaged with the second limiting portion 52, so that the wearable device returns to the original state.

Optionally, the raised structure 123 is a graded structure. The side of the gradual change towards the second elastic element 13 is the side of greater dimension. For example, the transition structure has an arcuate edge.

For example, when the first key 21 or the second key 22 is pressed alone, the first portion of the protrusion 123 cannot be driven to move out of the position between the first position-limiting member 41 and the second position-limiting member 42. The first bracket 12 is supported by the second elastic element 13 and inclined to the pressing side, and the protrusion 123 is held between the first limiting element 41 and the second limiting element 42 to form a support.

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

In one embodiment of the present application, as shown in fig. 8 to 11, the driving device includes an electromagnetic relay 17, and the first limiting member 41 and the second limiting member 42 are magnetic members;

Under the condition that 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 polarities of the electromagnetic relay 17 and the first limiting member 41 repel each other, and the polarities of the electromagnetic relay 17 and the second limiting member 42 repel each other, so that a fourth distance is formed between the first limiting member 41 and the second limiting member 42.

In the embodiment of the present application, the first limiting member 41 and the second limiting member 42 are moved by changing the magnetic field generated by the electromagnetic relay 17 to form an attraction or repulsion effect with the magnetic member. This can effectively operate the matching relationship between the first limiting member 41 and the first limiting portion 51, and the matching relationship between the first limiting member 41 and the third limiting portion 71. The matching relationship between the second limiting member 42 and the second limiting portion 52 and the matching relationship between the second limiting member 42 and the fourth limiting portion 72 can also be effectively operated.

For example, by changing the current direction of the electromagnetic relay 17, the electrodes on both sides of the electromagnetic relay 17 are changed, and the fitting relationship between the electromagnetic relay 17 and the first stopper 41 and the second stopper 42 is changed.

In one embodiment, as shown in fig. 8 to 11, the driving means includes an electromagnetic relay 17 and a third elastic member 18;

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 a second distance is formed between the first limiting member 41 and the second limiting member 42;

the driving device in the third state includes that the polarities of the electromagnetic relay 17 and the first limiting member 41 are attracted, the polarities of the electromagnetic relay 17 and the second limiting member 42 are attracted, and the third elastic member 18 is in the fourth deformation state, in which a third distance is formed 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.

The driving device in the fourth state includes that the electromagnetic relay 17 is in a power-off state, and the third elastic member 18 is in a fifth deformation state. The electromagnetic relay 17 is powered off, and thus, the first limiting member 41 and the second limiting member 42 cannot be attracted, and the compressed third elastic member 18 extends to push the first limiting member 41 and the second limiting member, so that a fourth distance is formed between the first limiting member 41 and the second limiting member 42.

In the embodiment of the 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, so as to maintain a second distance between the first limiting member 41 and the second limiting member 42.

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 energized and magnetized, and the first limiting member 41 and the second limiting member 42 can be attracted, and the third elastic member 18 is compressed. Thereby maintaining the wearable device in the first state.

The first button 21 moves to the third position, the second button 22 moves to the fourth position, so that the electromagnetic relay 17 is powered off and cannot absorb 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 cooperates with the fourth limiting portion 72. Thereby maintaining the wearable device in the second state.

Optionally, after a preset time period after the wearable device is in the first state, the electromagnetic relay 17 is automatically powered off. Thereby the wearing equipment is automatically switched to the second state.

After the wearable device is in the second state, the first button 21 and the second button 22 are pressed simultaneously, so that the third elastic member 18 pushes the first limiting member 41 to be matched with the first limiting portion 51, and the third elastic member 18 pushes the second limiting member 42 to be matched with the second limiting portion 52.

In one embodiment of the present application, as shown in fig. 6, the housing 1 is provided with a first guide slot 161 and a second guide slot 162, the first limiting member 41 is located in the first guide slot 161, and the second limiting member 42 is located in the second guide slot 162.

The first guide slot 161 provides a path limit for the first limiting member 41 to move, and the second guide slot 162 provides a path limit for the second limiting member 42 to move. Therefore, the first limiting part 41 and the first limiting part 51 can be matched more accurately, the second limiting part 42 and the second limiting part 52 can be matched more accurately, and the switching accuracy of the first limiting part 41 and the second limiting part 42 between the first state and the second state is guaranteed.

In an embodiment of the present application, as shown in fig. 4 to 11, the first limiting portion 51 is a first groove structure, the second limiting portion 52 is a second groove structure, and when the wearable device is in the first state, the first limiting member 41 abuts against a side wall of the first groove structure, and the second limiting member 42 abuts against a side wall of the second groove structure.

The third limiting portion 71 is a first protruding structure, the fourth limiting portion 72 is a second protruding structure, and when the wearable device is in the second state, the first limiting member 41 abuts against the first protruding structure, and the second limiting member 42 abuts against the second protruding structure.

The first groove structure and the second groove structure can be the same groove structure, and the groove structure is simple in forming and convenient to produce and process. And the groove structure is easier to form matching with the limiting piece to limit the movement of the key.

Taking the first key 21 as an example, the first groove structure is matched with the first limiting member 41. In the first state, the first position-limiting member 41 extends into the first groove structure. The first limiting member 41 abuts against an inner wall of the first groove structure facing away from the outer side of the first key 21 to limit the outward movement of the first key 21.

The first protruding structure and the second protruding structure can adopt the same protruding structure, and the protruding structure is simple in forming and convenient to produce and process.

In an embodiment of the present application, the housing 1 is further provided with a first key hole 31 and a second key hole 32, a fourth elastic member 61 is disposed in the first key hole 31, a fifth elastic member 62 is disposed in the second key hole 32, the fourth elastic member 61 abuts against the first key 21, and the fifth elastic member 62 abuts against the second key 22;

with the wearable device in the first state, the fourth elastic member 61 and the fifth elastic member 62 are both in a compressed state;

when the wearable device is in the second state, the fourth elastic element 61 and the fifth elastic element 62 are both extended, so that the first button 21 and the second button 22 can move a first distance to the outside of the housing 1.

In the process that the wearable device is switched from the first state to the second state, the fourth elastic member 61 pushes the first button 21 to move a first distance to the outside of the housing 1, and the first limiting member 41 and the third limiting portion 71 cooperate to limit the first button 21 to continue moving outward. The fifth elastic element 62 pushes the second button 22 to move a first distance to the outside of the housing 1, and the second limiting element 42 cooperates with the fourth limiting portion 72 to limit the second button 22 to move outwards.

For example, the key has a head and a shaft, the head being larger in size than the shaft. The fourth elastic member 61 is sleeved on the rod portion of the first button 21 and abuts against the head portion, and the fifth elastic member 62 is sleeved on the rod portion of the second button 22 and abuts against the head portion.

Taking the first button 21 as an example, in the first state, the head presses the fourth elastic member 61 to compress. In the second state, the compressed fourth elastic member 61 is extended to support the first button 21 to move outward. The first distance of movement may be set according to the actual desired size of the first key 21. The second key 22 and the first key 21 adopt the same structural scheme.

For example, the first key hole 31 and the second key hole 32 are both countersunk holes, and the fourth elastic member 61 and the fifth elastic member 62 are disposed on steps of the countersunk holes so that the head can be inserted into the countersunk holes.

The fourth elastic member 61 and the fifth elastic member 62 may be elastic telescopic structures, such as springs, elastic sheets, and the like.

Alternatively, the third stopper portion 71 and the fourth stopper portion 72 may be projections projecting from the shaft portion. For example, when the first key 21 and the second key 22 move to the outside. When the protrusion on the first key 21 moves to the first position-limiting member 41, a stop is formed, and when the protrusion on the second key 22 moves to the second position-limiting member 42, a stop is formed, and at this time, the first key 21 and the second key 22 move by a first distance.

Under the condition that the second button 22 is located at the second position and the first button 21 is located at the original position, the second limiting member 42 is engaged with the second limiting portion 52, the second button 22 is abutted against the first bracket 12, the first bracket 12 rotates around the rotating shaft 15 to be abutted against the second trigger switch 92, and the second trigger switch 92 is in a trigger state.

When activated individually, the first trigger switch 91 and the second trigger switch 92 respond to a different function than when activated simultaneously.

For example, in an embodiment where the first button 21 and the second button 22 are pressed simultaneously against the first support 12. The two arms of the first bracket 12 are pressed against one of the first trigger switch 91 and the second trigger switch 92, respectively, so that both the first trigger switch 91 and the second trigger switch 92 are triggered. When pressed alone, the depressed arm triggers a corresponding one of the first and second trigger switches 91 and 92. As shown in fig. 5, the first button 21 presses the first arm 121 to trigger the first trigger switch 91.

The rotation shaft 15 serves as a support shaft for the rotation of the first bracket 12, so that the first bracket 12 rotates and activates a corresponding activation switch when one of the first button 21 and the second button 22 is pressed.

For example, when the first key 21 is pressed alone, the first limiting member 41 is located in the first groove structure, so that the first limiting member 41 and the first limiting portion 51 are kept engaged. When the second key 22 is pressed alone, the second limiting member 42 is located in the second groove structure, so that the second limiting member 42 and the second limiting portion 52 are kept engaged.

In the embodiment of the present application, pressing the first key 21 alone can trigger the first trigger switch 91. Pressing the second key 22 alone can activate the second trigger switch 92 alone.

Alternatively, in an embodiment where the pressing of the first key 21 and the second key 22 simultaneously can trigger the electromagnetic relay 17 to be energized so as to be attracted to the first stopper 41 and the second stopper 42. Pressing the first key 21 alone triggers the first trigger switch 91 and pressing the second key 22 alone triggers the second trigger switch 92.
