In one 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 side wall of the mounting groove 110 being provided with a mounting hole 111;

a band 20 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, and the connecting shaft 500 can be driven to axially move, so that the connecting shaft 500 has 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connecting shaft 500 is inserted into the mounting hole 111, and in the second position, the connecting shaft 500 is withdrawn from the mounting hole 111.

The connecting shaft 500 can axially move under the driving of the rotating shaft 400, the movement stroke of the connecting shaft 500 has a first position and a second position, and the connecting shaft 500 can be inserted into the mounting hole 111 after moving to the first position, 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the equipment main body 10; when the connecting shaft 500 moves to the second position, the mounting hole 111 can be withdrawn, so that the belt body 20 can freely enter and exit the mounting groove 110.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 pre-driving, the belt body 20 is inserted into the installation groove 110, after the belt body 20 is inserted into place, the end part of the connecting shaft 500 is opposite to the installation hole 111, at the moment, 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 equipment 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20 is detached, the connecting shaft 500 is driven to move to the first position, and after the connecting shaft 500 is withdrawn from the mounting hole 111, the belt body 20 can be pulled out from the mounting groove 110, so that the belt body 20 is separated from the apparatus main body 10. In the present invention, the user drives the rotation shaft 400 to rotate, i.e. drives the connection shaft 500 to move to the first position or the second position, so that the connection shaft 500 can be correspondingly inserted into or withdrawn from the mounting hole 111, the operation is very simple, the user can conveniently and rapidly disassemble and assemble the belt body 20 and the device main body 10, and the operation experience of the user for replacing the belt body 20 is facilitated.

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 convex part, the extending direction of the first guiding structure forms an included angle with the axial direction and the circumferential direction of the connecting shaft 500, a second guiding structure for limiting the circumferential rotation of the connecting shaft 500 and guiding the 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 kept relatively fixed with the belt body 20 in the axial direction; the rotation shaft 400 rotates to enable the transmission protruding portion to move along the extending direction of the first guiding structure, so as to drive the connecting shaft 500 to axially move. It will be appreciated that the first guide structure extends obliquely, and the circumferential rotation of the rotation shaft 400 can be converted into the axial movement of the connection shaft 500 by 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 axial movement of the connection shaft 500. When the rotation shaft 400 rotates, the connecting shaft 500 is limited by the second guiding structure and cannot rotate along with the rotation shaft 400, so that the transmission convex part moves along the second guiding structure, and the rotation shaft 400 is fixed relative to the belt body 20 in the axial direction, so that the rotation shaft 400 rotates relative to the belt body 20, the connecting shaft 500 moves axially relative to the belt body 20, and the connecting shaft 500 can be driven to move axially by driving the rotation shaft 400 to rotate. Of course, in other embodiments, the mounting hole 111 may be provided with an internal thread, the rotation shaft 400 is provided with a screw hole for connecting the connection shaft 500, two ends of the connection shaft 500 are respectively screwed to the mounting hole 111 and the screw hole provided on the rotation shaft 400, and by driving the rotation shaft 400 to rotate in one direction, one end of the connection shaft 500 can be screwed out of the screw hole of the rotation shaft 400, and the other end is screwed into the mounting hole 111, so that the connection 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 former direction), one end of the connection shaft 500 is rotated out of the mounting hole 111, and the other end is rotated into the screw hole of the rotation shaft 400, so that the connection shaft 500 is withdrawn out of the mounting hole 111.

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

Further, in the present embodiment, two or four guiding inclined planes 521 are formed at the end of the connecting shaft 500, and each two adjacent guiding inclined planes 521 share one of the first dead points a or one of the second dead points b and extend away from the shared first dead point a or second dead point b. It will be appreciated 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 the first dead point a and the second dead point b, the guide slopes 521 can be connected in a wavy shape at the end of the connecting shaft 500, wherein the first dead point a is located at the peak, the second dead point b is located at the trough, and the guide slopes 521 are formed between the adjacent peaks and troughs. In this way, in the transmission process between the connecting shaft 500 and the rotating shaft 400, the first dead point a and the second dead point b are not end points, the transmission convex part 410 can circularly move along the guiding inclined planes 521, and the rotating shaft 400 can rotate more freely, so that the operation of a user is more convenient. In particular, in order to facilitate the transmission between the connection shaft 500 and the rotation shaft 400, the number of the guide inclined surfaces 521 is preferably not excessively large, and two or four. In addition, in the present embodiment, when the driving protrusion 410 is located at the second dead point b, the user drives the rotation shaft 400 in different directions, so that the driving protrusion 410 moves to the first dead point a along different guiding inclined planes 521, and the connection shaft 500 can be moved from the second position to the second position, so that the connection shaft 500 is inserted into the mounting hole 111. In this way, when the user drives the rotation shaft 400 to rotate, the user does not need to specifically identify the direction, and the operation is simpler and more convenient.

As shown in fig. 13, when the driving protrusion 410 moves to the second dead point b, the driving protrusion 410 is located at the trough and is clamped by two adjacent guiding inclined planes 521, the driving protrusion 410 can be stably located at the second dead point b, and correspondingly, the connecting shaft 500 can be stably located at a fixed position after being withdrawn from the mounting hole 111, so that the insertion and extraction of the belt 20 in the mounting groove 110 are not affected; as shown in fig. 12, when the driving protrusion 410 moves to the first dead point a, the driving protrusion 410 is located at the peak, but is difficult to stably locate at the peak, so in this embodiment, a limit groove 524 is formed in the peak, where the limit groove 524 is located, that is, the first dead point a, and the driving protrusion 410 is engaged with the limit groove 524, that is, the driving protrusion 410 is stably located at the first dead point a, and accordingly, the connection shaft 500 is also stably kept 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 point a, the driving protrusion 410 can be stably located at the first dead point a by limiting other positions of the rotation shaft 400.

Further, in the present embodiment, as shown in fig. 7, a first insertion groove 522 facing the rotation shaft 400 is provided at an end of the connection shaft 500 near the rotation shaft 400, the guiding inclined surface 521 is formed on a side wall of the first insertion groove 522, as shown in fig. 5, a first insertion portion 420 is provided at an end of the rotation shaft 400 near the connection shaft 500, as shown in fig. 12 and 13, the first insertion portion 420 may be inserted into the first insertion groove 522, and the driving protrusion 410 is disposed on an outer circumference of the first insertion portion 420 to be matched with the guiding inclined surface 521. Specifically, when the driving protrusion 410 is located at the second dead point b, the first inserting portion 420 is inserted into the first inserting groove 522 to drive the rotation shaft 400 to rotate, and the driving protrusion 410 moves along the sidewall (i.e. the guiding slope 521) of the first inserting groove 522 toward the first dead point a, and meanwhile, the first inserting portion 420 rotates in the first inserting groove 522, so that the rotation stability of the rotation shaft 400 can be improved, and the first inserting portion 420 is not separated from the first inserting groove 522 until the driving protrusion 410 moves to the second dead point b. In addition, during the transmission process of the rotation shaft 400 and the connection shaft 500, the first inserting groove 522 can also be located at the first inserting portion 420, so as to avoid interference between the end of the rotation shaft 400 and the end of the connection shaft 500. Of course, in other embodiments, the transmission protrusion 410 may be protruded at the edge of the end of the rotation shaft 400, and the guide slope 521 may be formed corresponding to the periphery of the end of the connection shaft 500, so that the end of the connection shaft 500 may not be provided with a groove structure, and interference between the end of the rotation shaft 400 and the end of the connection 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 toward the second position under the action of the elastic member. In this embodiment, the rotation of the rotation shaft 400 drives the connection shaft 500 to insert into the mounting hole 111, and drives the connection shaft 500 to withdraw from the mounting hole 111, which is mainly accomplished by the elastic action of the spring 700.

Specifically, when the belt body 20 is mounted, the belt body 20 with the connecting shaft 500 at the second position is inserted into the mounting groove 110, and then the rotating shaft 400 is driven to rotate, so as to drive the connecting shaft 500 to move toward the first position. In this process, the elastic member is subjected to a force and is elastically deformed, and the driving protrusion 410 moves from the second dead point b toward the first dead point a along the guiding slope 521 correspondingly. When the connecting shaft 500 moves to the first position and is inserted into the mounting hole 111, the transmission protrusion 410 is correspondingly positioned in the limit groove 524 at the first dead point a, after the external force is removed, the circumferential rotation of the rotating shaft 400 is limited, the axial pushing force of the rotating shaft 400 to the connecting shaft 500 can offset the axial component force of the elastic member, and the connecting shaft 500 is relatively fixed with the device main body 10 in the axial direction, so that the belt body 20 can be locked to the device main body 10.

When the belt body 20 is detached, the rotation shaft 400 needs to be driven to rotate appropriately, so that the transmission protrusion 410 can leave the limit groove 524, and therefore, the limit of the connection shaft 500 on the circumferential rotation of the rotation shaft 400 is released, the axial acting force of the rotation shaft 400 on the connection shaft 500 is weak, after that, the connection shaft 500 can be driven to move to the second position without being driven by external force, the elastic potential energy of the elastic member is released, and the transmission protrusion 410 correspondingly moves to the second dead center b along the guide inclined plane 521, thereby driving the rotation shaft 400 to rotate circumferentially. When the driving protrusion 410 reaches the second dead point b at the trough, the elastic member may be correspondingly restored to a natural state, and the axial direction of the connecting shaft 500 is hardly stressed, so that the elastic member may still have elastic potential energy in the second position in the exit mounting hole 111, and at this time, the rotating shaft 400 may apply an axial force to the trough of the second dead point b through the driving protrusion 410 to counteract the axial component of the elastic force of the elastic member, and the connecting shaft 500 may be stably positioned in the second position. That is, the connection shaft 500 is stably maintained in a state of being withdrawn from the installation space, whereby the user can easily withdraw the band 20 from the installation groove 110 to separate the band 20 from the apparatus body 10.

Of course, in other embodiments, when the belt body 20 is detached, the user drives the rotation shaft 400 to rotate circumferentially, so that the transmission protrusion 410 is separated from the limit groove 524, and drives the connecting shaft 500 to move axially from the first position to the second position, at this time, the rotation shaft 400 can be driven by the connecting shaft 500 to rotate circumferentially, the transmission protrusion 410 can also move along the guiding inclined plane 521 to the second dead center b, and the user can smoothly drive the connecting shaft 500 to the second position, and the connecting shaft 500 is withdrawn from the mounting hole 111, so that the belt body 20 can be separated from the apparatus main body 10.

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