[0051] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0052] like Figure 1-23As shown, a wearable device with an unobstructed image acquisition end includes a wearable device body 1. Preferably, the wearable device body 1 can be selected to use a watch or a bracelet and other wearable devices that can be worn on the forearm or wrist. The wearable device body 1 is connected to a mounting portion 2 in an external convex shape. Preferably, the mounting portion 2 can be selected in a cylindrical shape or a flat plate shape. The shape of the mounting portion 2 can be selected according to specific usage requirements. An optical module 3 is installed on the mounting portion 2. Optionally, the optical module 3 includes an optical sensor and a light source component. Alternatively, the optical module 3 is an optical sensor that can use natural light (such as a camera, etc.). When the user wears the wearable device body 1, the mounting portion 2 can exceed the connection position between the user's wrist and hand so that the optical module 3 is not blocked in the direction of image acquisition toward the hand. Therefore, when the user wears the wearable device provided by the present invention, the optical module 3 can well collect image information of the hand, and finally the input or output of the instruction can be guaranteed to be accurate and stable.

[0053] Optionally, the mounting portion 2 can move relative to the wearable device body 1, so that the moving mounting portion 2 with the optical module 3 is locked at a position beyond the connection position between the user's wrist and hand.

[0054] Furthermore, the mounting portion 2 is connected to the wearable device body 1 through an ejection mechanism, a rotation mechanism, a flipping mechanism or a pushing mechanism to enable the mounting portion 2 to move relative to the wearable device body 1. Of course, those skilled in the art can also adopt other mechanisms in the prior art that can enable the mounting portion 2 to move relative to the wearable device body 1 so that the mounting portion 2 with the optical module 3 is locked at a position beyond the connection position between the user's wrist and hand.

[0055] Optionally, the ejection mechanism includes a first receiving groove 401 provided in the wearable device body 1, the first receiving groove 401 can accommodate the installation part 2 to enter, a first sliding block 402 that can slide inside the first receiving groove 401 is provided, the first sliding block 402 is connected to the inner wall of the first receiving groove 401 through a first elastic reset member 409, preferably, the first elastic reset member 409 adopts a compression spring, a blind hole 403 is provided on the surface where the first sliding block 402 contacts the first receiving groove 401, a second elastic reset member is provided in the blind hole 403, preferably, the second elastic reset member adopts a compression spring, one end of the second elastic reset member is connected to the limit block 405, the limit block 405 can move along the blind hole 403, the first receiving groove 401 A limiting hole 406 is provided on the wall of the wearable device, a lifting block 407 is provided in the limiting hole 406, a lifting rod 408 is fixedly connected to the lifting block 407, and the lifting rod 408 passes through the limiting hole 406 and extends to the outside of the wearable device body 1. When the first sliding block 402 slides along the first receiving groove 401 to allow the mounting portion 2 to enter the first receiving groove 401, the limiting block 405 and the limiting hole 406 have

[0056] The corresponding overlapping position and the limit block 405 can enter the limit hole 406; when the mounting portion 2 moves toward the first receiving groove 401

[0057] When the optical module 3 needs to be ejected beyond the connection position between the wrist and the hand to conveniently use the optical module 3, the lifting block 407 can push the limit block 405 out of the limit hole 406 by pressing 408 manually. At this time, the limit hole 406 no longer has a limiting effect on the limit block 405. Then, the first elastic reset member 409 is used to eject the installation part 2 with the optical module.

[0058] Optional, such as Figure 4 and 5As shown, the ejection mechanism includes a second accommodating groove 417 opened in the wearable device body 1, the second accommodating groove 417 can accommodate the installation part 2 to enter, and a second sliding block 411 that can slide inside the second accommodating groove 417 is arranged, and the second sliding block 411 is connected to the inner wall of the second accommodating groove 417 through a third elastic reset member 412. Preferably, the third elastic reset member 412 adopts a compression spring, and the side surface of the second sliding block 411 that contacts the second accommodating groove 417 is an inclined surface, and the inclined surface is arranged away from the installation part 2. A mounting groove 413 is opened on the surface of the wearable device body 1, and the length direction of the mounting groove 413 is perpendicular to the length direction of the second accommodating groove 417. A limiting rod 414 passes through the mounting groove 413, and the limiting rod 414 extends to the inside of the second accommodating groove 417, and the side surface of the limiting rod 414 facing the installation part 2 is an inclined surface, and the other end of the limiting rod 414 is fixedly connected There is a handle 415, which is connected to the mounting groove 413 through a fourth elastic reset member 416. Preferably, the fourth elastic reset member 416 adopts a compression spring. When the second sliding block 411 slides along the second accommodating groove 417 to allow the mounting portion 2 to enter the second accommodating groove 417, the inclined surface of the second sliding block 411 can contact the inclined surface of the limiting rod 414 to apply a component of force to the limiting rod 414 toward a direction away from the second accommodating groove 417. After the second sliding block 411 continues to move over the limiting rod 414, the other side plane of the second sliding block 411 can contact the other side plane of the limiting rod 414. At this time, the limiting rod 414 has a limiting effect on the second sliding block 411, so that the mounting portion 2 is in a reset and retracted state. When the mounting portion 2 needs to be ejected, the handle 415 is pulled manually to make the limiting rod 414 disengage from the limitation on the second sliding block 411. At this time, the mounting portion 2 is ejected through the action of the third elastic reset member 412.

[0059] Of course, the present invention can also adopt other types of ejection mechanisms, such as an electromagnetic ejection mechanism to realize the ejection and resetting of the installation part, or by opening a receiving groove in the wearable device body to inject gas and discharge gas to realize the ejection and resetting of the installation, or by utilizing the principle that like poles repel each other and opposite poles attract each other between magnets, a magnet is fixedly installed on the installation part 2, and another magnet is arranged into a rotatable structure, and by rotating one magnet to change its magnetic pole direction toward the other magnet, the two magnets can realize magnetic repulsion and attraction, thereby realizing the ejection and resetting of the installation part, and so on.

[0060] Optional, such as Figure 6 and 7 As shown, the rotating mechanism includes a third receiving groove 421 which is opened through the wearable device body 1. Figure 6 and Figure 7The third receiving slot 421 is provided at the lower position of the wearable device 1. Of course, the third receiving slot 421 can also be provided at other positions according to actual needs. The end of the mounting portion 2 away from the optical module 3 is located in the third receiving slot 421. The mounting portion 2 is rotatably connected to the third receiving slot 421 through the first pin shaft 422. When the mounting portion 2 rotates around the first pin shaft 422, the mounting portion 2 can enter the third receiving slot 421 and be accommodated, or it can be rotated to the outside of the third receiving slot 421, and the first pin shaft 422 is connected to the wall of the third receiving slot 421 through a damping limit mechanism so that the position of the mounting portion 2 can be locked after rotation. A toggle block 424 is fixedly connected to the mounting portion 2. When the mounting portion 2 enters the third receiving slot 421 and is accommodated, the toggle block 424 can be manually pushed to rotate the mounting portion 2 out.

[0061] Optional, such as Figure 8 As shown, the damping limit mechanism includes a damping protrusion 423 formed on the first pin shaft 422 along the circumferential surface of the first pin shaft 422, and the first pin shaft 422 is installed in a mounting hole on the wall of the third accommodating groove 421, and the inner wall of the mounting hole is provided with a damping groove used in conjunction with the damping protrusion 423. When the first pin shaft 422 needs to rotate in the mounting hole, it is necessary to overcome the deformation caused by the damping protrusion 423 being separated from the damping groove in order to rotate, thereby keeping the mounting part 2 in a locked state without the action of external force. When the mounting part 2 needs to be rotated into the third accommodating groove 421 or rotated out of the third accommodating groove 421, it can be pushed by manpower.

[0062] Optional, such as Figure 9-11 As shown, the damping limit mechanism includes a

The handle 425 is screwed to the external thread through the internal thread hole, and the handle 425 can be pressed into contact with the surface of the wearable device body 1. Therefore, when the handle 425 rotates relative to the first pin shaft 422 and is pressed into contact with the surface of the wearable device body 1, the friction between the handle 425 and the surface of the wearable device body 1 achieves a locking effect on the mounting part 2. When the handle 425 rotates in the opposite direction relative to the first pin shaft 422 and does not contact the surface of the wearable device body 1, the first pin shaft 422 can rotate freely with the mounting part 2.

[0064] Of course, the damping limit mechanism can also adopt the interference fit method between the pin shaft 422 and the mounting hole on the wall of the third receiving groove 421 to increase the friction between the pin shaft 422 and the mounting hole on the wall of the third receiving groove 421 to achieve damping limit, or directly connect the pin shaft 422 to the damper; and the third receiving groove 421 that is opened through the wearable device body 1 can be set at the lower part, middle part, upper part or other positions of the wearable device body 1.

[0066] Optional, such as Fig.12 and 13 As shown, the locking limit mechanism is a structure in which the second pin shaft 433 is interference-fitted with the mounting hole on the wearable device body 1, and locking of any position of the mounting part 2 is achieved by increasing the friction between the second pin shaft 433 and the mounting hole on the wearable device body 1.

[0067] Optional, such as Fig.14 As shown, the locking and limiting mechanism includes an iron piece 434 fixedly arranged on the mounting portion 2 and a magnet 435 fixedly arranged on the wearable device body 1, and when the mounting portion 2 is flipped around the second pin shaft 433, the iron piece 434 and the magnet 435 have overlapping magnetic attraction positions.

[0068] It should be noted that if Figure 12-14 As shown, a notch 431 can be opened on the wearable device body 1, so that the mounting portion 2 can be rotated into the notch 431 and the mounting portion 2 is flush with the plane of the wearable device body 1, so that when the optical module 3 is not in use, the mounting portion 2 and the optical module 3 are more beautiful and save space. The mounting portion 2 can also be set on one side or two symmetrical sides of the wearable device body 1. In this case, Fig.15 and 16 As shown, of course, the position of the mounting portion 2 can be set according to actual needs.
