[0041] The present invention provides a wearable device.

[0042] In an embodiment of the present invention, as Figures 1 to 4 shown, the wearable device includes:

[0043] A mounting base 100, provided with a first mounting groove 110;

[0044] A functional main body 200, detachably mounted in the first mounting groove 110, and the functional main body 200 is provided with a limiting card slot (not shown); and

[0045] A limiting member 300, rotatably connected to the mounting base 100 to have a locking position and an unlocking position; the limiting member 300 protrudes with a limiting card protrusion 310. In the locking position, the limiting card protrusion 310 protrudes and engages with the limiting card slot in the first mounting groove 110 to limit the functional main body 200 from detaching from the first mounting groove 110. In the unlocking position, the limiting card protrusion 310 disengages from the limiting card slot;

[0046] Wherein, the rotation axis of the limiting member 300 is parallel to the depth direction of the first mounting groove 110.

[0047] It can be understood that the wearable device has a wearing side. After the wearable device is worn on the human body, the wearing side fits against the human skin. The depth direction of the first mounting groove 110 is also the direction from the bottom wall of the first mounting groove 110 to its opposite notch. The bottom wall of the first mounting groove 110 is located on the side opposite to the wearing side. After the functional main body 200 is mounted on the mounting base 100, the thickness direction of the functional main body 200 is also the depth direction of the first mounting groove 110. In addition, the mounting base 100 is further connected with a wearing part 900, and the wearing part 900 can lock the mounting base 100 to the corresponding wearing position of the user for the user to wear the wearable device.

[0048] In the technical solution of the present invention, the limiting member 300 is rotatably connected to the mounting base 100, and its rotation axis is parallel to the depth direction of the first mounting groove 110, so that the relative positional relationship between the limiting convex 310 and the limiting groove of the functional body 200 can be switched between engagement and disengagement. Among them, when the limiting member 300 is in the locked position, the functional body 200 can be locked in the first mounting groove 110 by engaging the limiting member 300 with the limiting groove, so that the functional body 200 is limited from disengaging from the first mounting groove 110, thereby improving the connection stability between the functional body 200 and the mounting base 100, and effectively preventing the functional body 200 from detaching from the mounting base 100. In the prior art, the functional body 200 and the mounting base 100 are mainly connected by magnetic attraction, and the connection stability is poor. In the present invention, the connection stability between the functional body 200 and the mounting base 100 is greatly improved by the engagement of the limiting convex 310 and the limiting groove. In addition, in the wearable device of the present invention, the limiting member 300 can be rotated from the locked position to the unlocked position, so that the limiting convex 310 disengages from the mounting groove, and the functional body 200 can enter and exit the first mounting groove 110 without being interfered by the limiting convex 310, and the functional body 200 and the mounting base 100 can be disassembled and assembled conveniently and quickly.

[0049] Further, in this embodiment, as Figure 3 , Figure 4 and Figure 6 shown, the wearable device further includes a mounting bracket 400 fixed to the mounting base 100, and the limiting member 300 is rotatably mounted on the mounting bracket 400. In this embodiment, the limiting member 300 is indirectly connected to the mounting base 100 through the mounting bracket 400. In this way, the material of the mounting bracket 400 can be conveniently adjusted. On the one hand, the limiting member 300 can be smoothly and rotatably connected to the mounting bracket 400, and on the other hand, the mounting bracket 400 can stably provide a supporting force for the limiting member 300. Of course, in other embodiments, it may also be that the limiting member 300 is directly connected to the mounting base 100.

[0050] Further, in this embodiment, as Figures 2 to 5As shown, the mounting base 100 is further provided with a second mounting groove 120. The mounting bracket 400 is received in the second mounting groove 120. The first mounting groove 110 and the second mounting groove 120 are connected through a communication port 111. The limiting convex 310 movably penetrates through the communication port 111. By receiving the mounting bracket 400 in the second mounting groove 120, the mounting stability of the mounting bracket 400 on the mounting base 100 can be improved. Moreover, the exposure of the mounting bracket 400 is avoided, ensuring the structural stability of the mounting bracket 400. The communication port 111 allows the limiting convex 310 to pass through, enabling the limiting convex 310 to cooperate with the functional main body 200 mounted in the first mounting groove 110 to lock the functional main body 200 in the first mounting groove 110. Of course, in other embodiments, the mounting bracket 400 can also be received in the first mounting groove 110 together.

[0051] Further, in this embodiment, as Figure 2 shown, the second mounting groove 120 is provided with a rotating groove 121. The limiting member 300 is further provided with a rotating shaft 320. The rotating shaft 320 penetrates through the mounting bracket 400 and is rotatably connected to the rotating groove 121. In this way, the rotating shaft 320 can be rotatably engaged with both the mounting bracket 400 and the mounting base 100, which is beneficial to improving the rotation reliability of the limiting member 300. Of course, in other embodiments, the rotating shaft 320 can also be only rotatably connected to the mounting bracket 400.

[0052] Further, in this embodiment, please also refer to Figure 5 and Figure 6 , the second mounting groove 120 is provided with a fixing groove 122. The mounting bracket 400 is provided with a fixing convex portion 410. The fixing convex portion 410 is fixedly engaged in the fixing groove 122. In this way, the mounting stability of the mounting bracket 400 in the second mounting groove 120 can be ensured through the fixed engagement of the fixing convex portion 410 and the fixing groove 122, enabling the mounting bracket 400 to stably support the limiting member 300. Of course, in other embodiments, the mounting bracket 400 can also be fixed in the second mounting groove 120 by means of embedding, screw locking, or plugging.

[0053] Further, in this embodiment, as Figure 2As shown, the wearable device further includes a trigger button 500. The trigger button 500 has a part exposed outside the mounting base 100 and is slidably connected to the mounting base 100 to have an initial position and a trigger position. When the trigger button 500 slides from the initial position to the trigger position, it can drive the limiting member 300 to rotate from the locking position to the unlocking position. In this way, by pressing the trigger button 500, the limiting member 300 can be driven to rotate. When the trigger button 500 is pressed from the initial position to the trigger position, the limiting member 300 can correspondingly rotate from the locking position to the unlocking position, and the user can unlock the functional body 200 conveniently and quickly by pressing the trigger button 500. Of course, in other embodiments, it may also be that a rotating knob is connected to the rotating shaft 320 of the limiting member 300, and the rotating knob is arranged outside the mounting base 100, and the user can drive the limiting member 300 to rotate by rotating the rotating knob.

[0054] Further, in this embodiment, as Figures 6 to 9 shown, the wearable device further includes a pushing member 600 slidably connected to the mounting bracket 400. One end of the trigger button 500 abuts against the pushing member 600. A driving inclined surface 610 is provided at the other end of the pushing member 600, and a force-receiving inclined surface 331 is correspondingly provided on the limiting member 300. The driving inclined surface 610 abuts against the force-receiving inclined surface 331. In this way, when the limiting member 300 only has the freedom to rotate relative to the mounting bracket 400 and the pushing member 600 only has the freedom to slide relative to the mounting bracket 400, by the driving inclined surface 610 pushing against the force-receiving inclined surface 331, the sliding of the pushing member 600 can be converted into the rotation of the limiting member 300. Thus, when the trigger button 500 is pressed, the pushing member 600 can be driven to slide, thereby driving the rotation of the limiting member 300. Of course, in other embodiments, it may also be that the trigger button 500 directly cooperates with the limiting member 300 through an inclined surface structure. In this way, the rotation of the limiting member 300 can also be driven by the sliding of the trigger button 500.

[0055] Further, in this embodiment, as Figure 7As shown, a first elastic member 700 is also connected between the pushing member 600 and the limiting member 300. Under the action of the first elastic member 700, when the limiting member 300 is in the locking position, the trigger button 500 has a tendency to maintain at the initial position. Further, a second elastic member 800 is connected between the limiting member 300 and the mounting base 100. Under the action of the second elastic member 800, the limiting member 300 has a tendency to maintain at the locking position. Thus, when the trigger button 500 is not subjected to an external force, under the action of the second elastic member 800, the limiting member 300 maintains at the locking position, so that the limiting convex 310 can stably engage with the limiting slot to ensure the locking effect on the functional body 200. Under the action of the first elastic member 700, the trigger button 500 can maintain at the initial position and will not interfere with the limiting member 300. Moreover, the trigger button 500 maintained at the initial position is in a state where it can be pressed, which is convenient for the user to press when unlocking. In addition, when installing the functional body 200, the trigger button 500 can be first pressed to move it to the trigger position, so as to drive the limiting member 300 to rotate to the unlocking position. Then, the functional body 200 is installed in the first installation groove 110, and then the force applied to the trigger button 500 is removed. The limiting member 300 can return to the locking position under the action of the second elastic member 800. Thus, under the action of the first elastic member 700, the trigger button 500 is urged to return to the initial position. In this way, it is beneficial to improve the installation convenience of the functional body 200. Among them, the first elastic member 700 acts on the pushing member 600, and the pushing member 600 pushes the trigger button 500 to drive the trigger button 500 to return to the initial position. Under the action of the first elastic member 700, the trigger button 500 can be driven to reset faster. Of course, in other embodiments, it may also be that only an elastic member for resetting is provided between the mounting base 100 and the limiting member 300, and the limiting member 300 is used for pushing. Or, the pushing member 600 is respectively connected to the limiting member 300 or the mounting base 100 through two elastic members. The pushing member 600 is reset relative to the mounting base 100 under the action of the elastic member, so as to drive the trigger button 500 to reset by pushing, and drive the limiting member 300 to reset through another elastic member.

[0056] Further, in this embodiment, as Figure 7As shown, the limit member 300 is provided with a mounting shaft 350 and a mounting hole 360, the axes of the mounting shaft 350 and the mounting hole 360 are parallel to the rotation axis of the limit member 300, the second elastic member 800 is configured as a torsion spring, the spring body of the torsion spring is sleeved on the mounting shaft 350, one torsion arm of the torsion spring is inserted in the mounting hole 360, and the other torsion arm abuts against the mounting seat 100 on the side of the limit member 300 away from the limit clamp 310. Among them, the installation shaft 350, the installation hole 360 and the limit clamping protrusion 310 are all located on the same side of the rotating shaft 320. When the limit member 300 rotates from the locking position to the unlocking position, the limit clamping protrusion 310 will swing in the opposite direction of its convex setting direction, driving the torsion arms of the torsion spring to approach each other, so that the torsion spring undergoes elastic deformation and accumulates elastic potential energy. In this way, when the limit member 300 is in the unlocking position and the trigger button 500 is not subjected to external force, the limit member 300 can return to the locking position under the action of the torsion spring, and after the limit member 300 returns to the locking position, it can be stably in the locking position to ensure the locking effect on the functional body 200. Of course, in other embodiments, the second elastic member 800 can also be set as a spring, a spring, an elastic silicone or an elastic rubber.

[0057] Furthermore, in this embodiment, if Figure 8 As shown, the position-limiting member 300 is formed with a receiving groove 330, the force-bearing inclined surface 331 is formed in the receiving groove 330, and the push member 600 and the first elastic member 700 are both received in the receiving groove 330. In this way, the installation stability of the first elastic member 700 can be improved to ensure that the trigger button 500 can be stably reset, and the connection stability between the push member 600 and the position-limiting member 300 can be improved to avoid misalignment between the driving inclined surface 610 of the push member 600 and the force-bearing inclined surface 331 of the position-limiting member 300.

[0058] Furthermore, in this embodiment, please combine Figures 6 to 8 The receiving groove 330 has a notch penetrating the convex side of the position-limiting protrusion 310, and the mounting bracket 400 is provided with a covering portion 420 covering the notch on the side. The notch is provided so that the first elastic member 700 and the push member 600 can be more conveniently installed in the receiving groove 330, and then, by covering the notch with the covering portion 420 of the mounting bracket 400, a certain resistance effect can be exerted on the first elastic member 700 and the push member 600 in the receiving groove 330, so that the first elastic member 700 and the push member 600 can be stably installed in the receiving groove 330.

[0059] Furthermore, in this embodiment, if Figure 8As shown, the pushing member 600 is provided with a guiding convex portion 620. A guiding groove 340 is formed in the groove wall of the receiving groove 330. The extending direction of the guiding groove 340 is parallel to the driving inclined surface 610, and the guiding convex portion 620 is slidably connected to the guiding groove 340. It can be understood that the guiding convex portion 620 will slide along the extending direction of the guiding groove 340. In this way, the sliding fit between the guiding convex portion 620 and the guiding groove 340 can play a role in guiding the relative movement of the pushing member 600 and the limiting member 300 when the driving inclined surface 610 pushes against the force-receiving inclined surface 331, so that the pushing member 600 can more stably push the limiting member 300 to rotate.

[0060] Further, in this embodiment, as Figure 1 shown in FIGS. 1 and 2, there are two limiting card slots, two limiting members 300 and two trigger buttons 500 provided in a one-to-one correspondence. The two trigger buttons 500 are respectively located on opposite sides of the mounting base 100. Among them, the two limiting card protrusions 310 movably penetrate through the same side groove wall of the first mounting groove 110, and the two trigger buttons 500 are correspondingly located at opposite end faces of this side groove wall. The opposite side groove wall of this side groove wall extends obliquely inward in the direction close to the groove opening. The obliquely arranged side groove wall can limit the corresponding side of the functional body 200 from coming out. The other side of the functional body 200 can be limited by the engagement between the limiting card protrusions 310 of the two limiting members 300 and the two limiting card slots. In this way, the installation stability of the functional body 200 in the first mounting groove 110 can be improved. Moreover, the rotation of these two limiting members 300 and the driving of the corresponding trigger buttons 500 to drive the limiting members 300 operate independently and do not interfere with each other. That is, only when the trigger buttons 500 on both sides are pressed, the two limiting members 300 will be in the unlocked position, and the two limiting card protrusions 310 will disengage from the corresponding limiting card slots to unlock the functional body 200. In this way, it can be avoided that the user accidentally touches a certain trigger button 500, causing the functional body 200 to be unlocked and accidentally separated from the mounting base 100, resulting in damage or loss of the functional body 200. Of course, in other embodiments, the two trigger buttons 500 can also be provided on the same side of the mounting base 100, such as the upper surface of the mounting base 100.

[0061] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
