The invention provides a wearable device, which can be understood as comprising: the wrist-watch, intelligent wrist-watch or intelligent bracelet of wearing in the wrist, can wear the motion monitoring module of ankle to and can wear in the 3D display device of head etc..

In an embodiment of the present invention, as shown in fig. 1 to 4, the wearable device includes:

an apparatus main body 10;

a mounting groove 110 provided at an end of the apparatus body 10, a mounting hole 111 being provided at a side wall of the mounting groove 110;

a band body 20 which is connected to the mounting groove 110 in a pluggable manner; and

the connecting piece 30 is arranged at the end part of the belt body 20, the connecting piece 30 comprises a rotating shaft 400 and a connecting shaft 500 which are connected, the rotating shaft 400 is driven to rotate, the connecting shaft 500 can be driven to axially move, and the connecting shaft 500 is enabled to have a first position and a second position; in the first position, the connecting shaft 500 is inserted into the mounting hole 111, and in the second position, the connecting shaft 500 is withdrawn from the mounting hole 111.

Under the driving of the rotating shaft 400, the connecting shaft 500 can axially move, the moving stroke of the connecting shaft 500 has a first position and a second position, and the connecting shaft 500 moves to the first position, namely, can be inserted into the mounting hole 111, so that the belt body 20 is fixedly connected with the equipment main body 10; when the connecting shaft 500 moves to the second position, it can be withdrawn from the mounting hole 111, so that the belt body 20 can freely enter and exit the mounting groove 110.

When the belt body 20 is installed, the connecting shaft 500 is moved to the second position by the driver, the belt body 20 is inserted into the installation groove 110, the end of the connecting shaft 500 is aligned with the installation hole 111 after the belt body 20 is inserted in place, at this time, the connecting shaft 500 is driven to move to the first position, and after the connecting shaft 500 is inserted into the installation hole 111, the belt body 20 is fixedly connected to the main body 10; when the belt body 20 is detached, the connecting shaft 500 is driven to move to the first position, and after the connecting shaft 500 exits from the mounting hole 111, the belt body 20 can be pulled out from the mounting groove 110, so that the belt body 20 is separated from the main body 10. In the invention, the user drives the rotating shaft 400 to rotate, so that the connecting shaft 500 can be driven to move to the first position or the second position, so that the connecting shaft 500 can be correspondingly inserted into or withdrawn from the mounting hole 111, the operation is very simple, the user can conveniently and quickly disassemble and assemble the belt body 20 and the equipment main body 10, and the operation experience of replacing the belt body 20 by the user is improved.

Further, in this embodiment, one of the rotating shaft 400 and the connecting shaft 500 is provided with a first guiding structure, the other is provided with a transmission protrusion, an extending direction of the first guiding structure forms an included angle with an axial direction and a circumferential direction of the connecting shaft 500, a second guiding structure for limiting circumferential rotation of the connecting shaft 500 and guiding axial movement of the connecting shaft 500 is further provided between the belt body 20 and the rotating shaft 400, and the rotating shaft 400 is axially fixed relative to the belt body 20; the rotation shaft 400 rotates to enable the transmission convex part to move along the extending direction of the first guide structure, so as to drive the connecting shaft 500 to move axially. It can be understood that the first guide structure extends obliquely, the circumferential rotation of the rotation shaft 400 is converted into the axial movement of the connection shaft 500 through the transmission of the first guide structure, and the second guide structure has a portion extending in the axial direction of the connection shaft 500 to restrict the circumferential rotation of the connection shaft 500 while guiding the connection shaft 500 to perform the axial movement. When the rotating shaft 400 rotates, the connecting shaft 500 is limited by the second guiding structure and cannot rotate along with the rotating shaft 400, so that the transmission convex portion moves along the second guiding structure, and the rotating shaft 400 is axially fixed relative to the belt body 20, therefore, the rotating shaft 400 rotates relative to the belt body 20, and the connecting shaft 500 axially moves relative to the belt body 20, so that the connecting shaft 500 is driven to axially move by driving the rotating shaft 400 to rotate. Of course, in other embodiments, the mounting hole 111 may be provided with an internal thread, the rotating shaft 400 may be provided with a screw hole for connecting the connecting shaft 500, two ends of the connecting shaft 500 are respectively screwed into the mounting hole 111 and the screw hole provided on the rotating shaft 400, and by driving the rotating shaft 400 to rotate in one direction, one end of the connecting shaft 500 can be screwed out of the screw hole of the rotating shaft 400, and the other end can be screwed into the mounting hole 111, so that the connecting shaft 500 is inserted into the mounting hole 111; by driving the rotation shaft 400 to rotate in the other direction (i.e., the opposite direction to the previous direction), one end of the connection shaft 500 can be screwed out of the mounting hole 111, and the other end can be screwed into the screw hole of the rotation shaft 400, so that the connection shaft 500 can be withdrawn from the mounting hole 111.

Further, in the present embodiment, as shown in fig. 5, the transmission protrusion 410 is disposed at an end of the rotating shaft 400, as shown in fig. 7, the first guiding structure is a guiding inclined plane 521 formed at an end of the connecting shaft 500, and opposite ends of the guiding inclined plane 521 are respectively provided with a first dead point a and a second dead point b; when the transmission protrusion 410 moves to the first dead center a, the connection shaft 500 is correspondingly located at the first position, and when the transmission protrusion 410 moves to the second dead center b, the connection shaft 500 is correspondingly located at the second position. It is understood that the second dead point b is closer to the end of the connecting shaft 500 for insertion into the mounting hole 111 than the first dead point a, the driving protrusion 410 moves along the guide slope 521 between the first dead point a and the second dead point b, and the connecting shaft 500 moves axially between the first position and the second position correspondingly. When the transmission protrusion 410 moves to the first dead point a, the connection shaft 500 can correspondingly move to the first position to be inserted into the mounting hole 111; when the transmission protrusion 410 moves to the second dead point b, the connection shaft 500 can correspondingly move to the second position to exit the installation hole 111. In this embodiment, the circumferential rotation of the rotating shaft 400 can be converted into the axial movement of the connecting shaft 500 by the cooperation of the guide slope 521 and the transmission protrusion 410. Of course, in other embodiments, the first guiding structure may be disposed in a chute structure, or alternatively, the first guiding structure is disposed on the rotating shaft 400 and the transmission protrusion 410 is disposed on the connecting shaft 500.

Further, in this embodiment, two or four guide inclined planes 521 are formed at an end of the connecting shaft 500, and every two adjacent guide inclined planes 521 share one first dead center a or one second dead center b and extend away from the shared first dead center a or second dead center b. It can be understood that when an even number of guide slopes 521 are formed at the end of the connecting shaft 500, and two adjacent guide slopes 521 share one of a first dead point a and a second dead point b, the guide slopes 521 may be connected at the end of the connecting shaft 500 in a wave shape, wherein the first dead point a is located at the peak, the second dead point b is located at the valley, and the guide slopes 521 are formed between the adjacent peaks and valleys. Thus, in the transmission process between the connecting shaft 500 and the rotating shaft 400, neither the first dead point a nor the second dead point b is an end point, the transmission convex part 410 can circularly move along the guide inclined planes 521, and the rotating shaft 400 can rotate more freely, thereby being more convenient for the user to operate. In particular, in order to facilitate the transmission between the connecting shaft 500 and the rotating shaft 400, the number of the guide slopes 521 is not large, and two or four guide slopes are preferably provided. In addition, in the present embodiment, when the driving protrusion 410 is located at the second dead point b, the user drives the rotating shaft 400 in different directions, so that the driving protrusion 410 moves to the first dead point a along different guiding slopes 521, and the connecting shaft 500 can move from the second position to the second position, so that the connecting shaft 500 is inserted into the mounting hole 111. Thus, when the user drives the rotation shaft 400 to rotate, the user does not need to particularly distinguish the direction, and the operation is simpler and more convenient.

As shown in fig. 13, when the transmission convex portion 410 moves to the second dead point b, the transmission convex portion 410 is located at the wave trough and clamped by the two adjacent guiding inclined surfaces 521, the transmission convex portion 410 can be stably located at the second dead point b, and correspondingly, the connecting shaft 500 can also be stably located at a fixed position after exiting from the mounting hole 111, without affecting the insertion and extraction of the belt body 20 in the mounting groove 110; as shown in fig. 12, when the transmission convex portion 410 moves to the first dead point a, the transmission convex portion 410 is located at the peak, but is difficult to be stably located at the peak, so in the present embodiment, the peak is properly recessed to form a limiting groove 524, the position of the limiting groove 524 is the first dead point a, the transmission convex portion 410 is engaged with the limiting groove 524, that is, the peak can be stably located at the first dead point a, correspondingly, the connection shaft 500 can be stably maintained in the inserted state after being inserted into the mounting hole 111, so that the belt body 20 is locked to the apparatus main body 10. Of course, in other embodiments, when the driving protrusion 410 moves to the first dead center a, other positions of the rotating shaft 400 may be limited, so that the driving protrusion 410 can be stably located at the first dead center a.

Further, in this embodiment, as shown in fig. 7, one end of the connection shaft 500 close to the rotation shaft 400 is provided with a first insertion groove 522 facing the rotation shaft 400, and the guide slope 521 is formed on a side wall of the first insertion groove 522, as shown in fig. 5, one end of the rotation shaft 400 close to the connection shaft 500 is provided with a first insertion part 420, as shown in fig. 12 and 13, the first insertion part 420 is inserted into the first insertion groove 522, and the transmission protrusion 410 is disposed on an outer circumference of the first insertion part 420 to be matched with the guide slope 521. Specifically, when the transmission protrusion 410 is located at the second dead point b, the first inserting-connecting part 420 is inserted into the first inserting-connecting groove 522 to drive the rotation shaft 400 to rotate, the transmission protrusion 410 moves toward the first dead point a along the sidewall (i.e., the guide slope 521) of the first inserting-connecting groove 522, and meanwhile, the first inserting-connecting part 420 rotates in the first inserting-connecting groove 522 to improve the rotation stability of the rotation shaft 400 until the transmission protrusion 410 moves to the second dead point b, and the first inserting-connecting part 420 is separated from the first inserting-connecting groove 522. In addition, during the transmission of the rotating shaft 400 and the connecting shaft 500, the first insertion groove 522 may also give way to the first insertion part 420, so as to prevent the end of the rotating shaft 400 from interfering with the end of the connecting shaft 500. Of course, in other embodiments, the driving protrusions 410 may be protruded from the edge of the end of the rotating shaft 400, and the guiding slopes 521 may be correspondingly formed on the periphery of the end of the connecting shaft 500, so that the end of the connecting shaft 500 may not have a groove structure, and the interference between the end of the rotating shaft 400 and the end of the connecting shaft 500 may be avoided.

Further, in the present embodiment, the connecting member 30 further includes an elastic member, and the connecting shaft 500 has a tendency to move to the second position under the action of the elastic member. In this embodiment, the rotation of the rotating shaft 400 drives the connecting shaft 500 to be inserted into the mounting hole 111, and drives the connecting shaft 500 to exit from the mounting hole 111, which is mainly accomplished by the elastic action of the spring 700.

Specifically, when the belt body 20 is installed, the belt body 20 with the connecting shaft 500 at the second position is inserted into the installation groove 110, and then the rotating shaft 400 is driven to rotate, so as to drive the connecting shaft 500 to move to the first position. In the process, the elastic member can be acted by force and elastically deformed, and the transmission convex part 410 also moves along the guide inclined surface 521 from the second dead center b to the first dead center a correspondingly. When the connecting shaft 500 moves to the first position and is inserted into the mounting hole 111, the transmission protrusion 410 is located in the limiting groove 524 at the first dead point a, after the external force is removed, the circumferential rotation of the rotating shaft 400 is limited, and the axial pushing force of the rotating shaft 400 on the connecting shaft 500 can counteract the axial component of the elastic force of the elastic member, so that the connecting shaft 500 is axially fixed relative to the apparatus body 10, and the belt body 20 can be locked to the apparatus body 10.

When the belt body 20 is disassembled, the rotating shaft 400 needs to be driven to rotate properly, so that the transmission convex portion 410 can leave the limiting groove 524, and thus, the limitation of the connecting shaft 500 on the circumferential rotation of the rotating shaft 400 is released, the axial acting force of the rotating shaft 400 on the connecting shaft 500 is weak, and after that, the driving of external force is not needed any more, the elastic potential energy of the elastic member is released, so that the connecting shaft 500 can be driven to move to the second position, and the transmission convex portion 410 correspondingly moves to the second dead point b along the guiding inclined plane 521, thereby driving the rotating shaft 400 to rotate circumferentially. When the driving protrusion 410 reaches the second dead point b at the valley, the elastic member may be in a corresponding natural state, and at this time, the axial direction of the connecting shaft 500 is hardly stressed, so that the connecting shaft can be stably located at the second position in the withdrawing mounting hole 111, and the elastic member may still have elastic potential energy, and at this time, the rotating shaft 400 may apply an axial acting force to the valley of the second dead point b through the driving protrusion 410 to offset an axial component of the elastic force of the elastic member, and the connecting shaft 500 may also be stably located at the second position. That is, the connection shaft 500 is stably maintained in the state of being withdrawn from the installation space, and thus, the user can easily pull the belt body 20 out of the installation groove 110 to separate the belt body 20 from the apparatus main body 10.

Of course, in other embodiments, there may be no elastic member, when detaching the belt body 20, the user drives the rotating shaft 400 to rotate circumferentially first to make the transmission protrusion 410 separate from the limiting groove 524, and then drives the connecting shaft 500 to move axially from the first position to the second position, at this time, the rotating shaft 400 can be driven by the connecting shaft 500 to continue rotating circumferentially, the transmission protrusion 410 will also move towards the second stop b along the guiding inclined plane 521, and the user can also drive the connecting shaft 500 to the second position smoothly, and the connecting shaft 500 withdraws from the mounting hole 111, so that the belt body 20 can be separated from the device main body 10.

Further, in the present embodiment, as shown in fig. 7, the guide slope 521 includes a first guide slope 5211 and a second guide slope 5212, the first guide slope 5211 and the second guide slope 5212 are adjacently connected at an end of the connecting shaft 500, and an inclination angle of the first guide slope 5211 with respect to the axial direction of the connecting shaft 500 is greater than an inclination angle of the second guide slope 5212 with respect to the axial direction of the connecting shaft 500, wherein the first guide slope 5211 is used for guiding the movement of the power transmission protrusion 410 during the movement of the power transmission shaft from the second position to the first position, and the second guide slope 5212 is used for guiding the movement of the power transmission protrusion 410 during the movement of the power transmission shaft from the first position to the second position.
