Fig. 2A-2B schematically illustrate a schematic of a mechanical structure for a wearable device according to an embodiment of the disclosure.
As shown in fig. 2A to 2B, the mechanical structure 10 for the wearable device includes a knob structure 100 and a transmission structure 200, wherein the transmission structure 200 is in contact with the knob structure 100.
According to the embodiment of the present disclosure, the knob structure 100 may be, for example, an adjusting portion of the mechanical structure 10, for example, a user may adjust the mechanical structure 10 by rotating the knob structure 100, where the knob structure 100 may be, for example, a disc-shaped structure, a cylindrical structure, a square-shaped structure, and the like, and the specific shape of the knob structure 100 is not limited by the embodiment of the present disclosure, and may be specifically set by a person skilled in the art according to the practical application.
According to the embodiment of the present disclosure, the transmission structure 200 may be, for example, a device capable of transmitting motion or power, for example, a structure in which a plurality of components cooperate with each other by means of meshing or friction, and the transmission structure 200 may be, for example, a structure formed by combining one or more of a gear, a rack, a conveyor belt, and the like. The specific components of the transmission structure 200 are not limited in the embodiments of the present disclosure, and it can be understood that, as long as the transmission structure 200 is ensured to meet the transmission requirements of the mechanical structure of the present disclosure, a person skilled in the art can specifically set the components and the connection modes of the transmission structure 200 according to practical application situations.
According to the embodiment of the present disclosure, the transmission structure 200 may be in contact with the knob structure 100, for example, the transmission structure 200 may be in direct contact with the knob structure 100, or the transmission structure 200 may be in indirect contact with the knob structure 100 through other components. It can be understood that the contact manner between the transmission structure 200 and the knob structure 100 is not limited in the embodiments of the present disclosure, for example, the contact manner may be gear engagement contact, friction contact of a transmission belt, or the like, as long as the adjustment function of the mechanical structure protected by the present disclosure can be realized by driving the transmission structure 200 to move through the movement of the knob structure 100.
According to the embodiment of the present disclosure, in the first operating state, the knob structure 100 can drive the transmission structure 200 to move, and in the second operating state, the knob structure 100 can move relative to the transmission structure 200.
According to an embodiment of the present disclosure, the first operating state may be, for example, an operating state in which the mechanical structure satisfies a certain condition, for example, when the mechanical structure is used as a structure for adjusting the tightness between the wearable device and the user, the first operating state may for example be a state in which the fit between the wearable device and the user is loose, in this state, the knob structure 100 can, for example, drive the transmission structure 200 to move, for example, by rotating the knob structure 100, the transmission structure 200 contacting with the knob structure 100 is driven to move, the size of the mechanical structure is adjusted through the movement of the transmission structure 200, the degree of tightness of fit between the mechanical structure and a user is adjusted through the size change of the mechanical structure, for example, the knob structure 100 may be rotated to tighten the fit between the mechanical structure and the user, or may be rotated to loosen the fit between the mechanical structure and the user.
According to the embodiment of the present disclosure, the second working state may be, for example, a working state in which the mechanical structure meets another condition, for example, a tight fit state between the wearable device and the user, in this state, the knob structure 100 moves relative to the transmission structure 200, for example, in the tight fit state, the knob structure 100 continues to be rotated, the transmission structure 200 is no longer driven by the knob structure 100, for example, the knob structure 100 only moves relative to the transmission structure 200 and no longer plays a role in adjusting the size of the mechanical structure, so that when the mechanical structure is in the tight fit state with the user, the knob structure 100 continues to be adjusted and the mechanical structure 10 does not continue to be tightened to fit the user, and therefore, an automatic adjustment mode through the mechanical structure plays a role in protecting the mechanical structure from being damaged and ensuring the safety of the user.
According to an embodiment of the present disclosure, the forces acting on the transmission structure 200 include: a first acting force including an acting force in the same direction as the rotation direction of the knob structure 100, and a second acting force including an acting force in the opposite direction to the rotation direction of the knob structure 100.
According to the embodiment of the present disclosure, when the mechanical structure 10 is in different operating states, the magnitude and direction of the force acting on the transmission structure 200 are different. The acting force acting on the transmission structure 200 includes, for example, a first acting force and a second acting force, the first acting force includes, for example, an acting force acting on the transmission structure 200 and driving the transmission structure to move 200 when the knob structure 100 rotates, and the direction of the acting force is, for example, the same as the rotation direction of the knob structure 100. The second acting force includes, for example, an acting force applied by the user on the transmission structure 200 when the mechanical structure 10 is attached to the user, for example, when the tightness degree of the attachment of the mechanical structure 10 to the user is adjusted by rotating the knob structure 100, for example, when the transmission structure 200 is moved by rotating the knob structure 100, the movement of the transmission structure 200 is subjected to the acting force of the user, and the acting direction of the second acting force is opposite to the rotating direction of the knob structure 100, so as to block the movement of the transmission structure 200, that is, the second acting force blocks the adjusting function of the mechanical structure 10.
According to an embodiment of the disclosure, the first operating state comprises: the first acting force is larger than the working state under the second acting force.
In the disclosed embodiment, during the adjustment of the mechanical structure 10, the movement of the mechanical structure 10 is in different operating states, for example, the different operating states are divided into a first operating state and a second operating state. The first operating state includes an operating state in which the first acting force is greater than the second acting force, that is, when the first acting force is greater than the second acting force, the knob structure 100 can, for example, drive the transmission structure 200 to move. Specifically, in a first working state, when the knob structure 100 rotates, the force applied by the knob structure 100 to the transmission structure 200 and driving the transmission structure 200 to move is greater than the force applied by the user to block the transmission structure 200 from moving, that is, the transmission structure 200 is driven by the knob structure 100 to adjust the size of the mechanical structure 10, and in the first working state, the effect of adjusting the tightness degree of the mechanical structure 10 attached to the user is achieved by selecting the knob structure 100.
According to an embodiment of the disclosure, the second operating state comprises: the first force is less than the operating condition under the second force.
In the disclosed embodiment, in the second operating state, i.e., in the operating state in which the first acting force is smaller than the second acting force, the knob structure 100 can move relative to the transmission structure 200. Specifically, in the second operating state, for example, during the rotation movement of the knob structure 100, the acting force of the knob structure 100 on the transmission structure 200 is smaller than the acting force of the user for obstructing the movement of the transmission structure 200, i.e., even if the knob structure 100 is selected, the rotation movement of the knob structure 100 will not bring the transmission structure 200 to move, and therefore, in the second operating state, the rotation movement of the knob structure 100 will not play a role in adjusting the size of the mechanical structure 10, for example, i.e., the movement of the knob structure 100 relative to the transmission structure 200 in the second operating state, so that the automatic stop adjustment function of the mechanical structure 10 is realized.
This disclosed embodiment is through mutually supporting of knob structure and transmission structure for the mechanical structure of this disclosed embodiment has different motion under different operating condition, drive the motion of transmission structure through rotatory knob structure under first operating condition, realize mechanical structure's regulatory function, under second operating condition, transmission structure no longer moves when continuing rotatory knob structure, realize mechanical structure automatic stop regulatory function, realize that the user need not rely on the elasticity degree that artificial perception adjusted mechanical structure, make this mechanical structure not fragile, use experience with this improvement user.

The stop structures 140 can fix the rolling elements 130 in the circumferential direction, in particular, for example, a gap of a certain size exists between two stop structures 140, in which gap one rolling element 130 can be placed, for example, wherein the rolling element 130 cannot perform a circumferential movement relative to the stop structures 140, for example.

To facilitate an understanding of the specific operation of the mechanical structure for the wearable device of the disclosed embodiment, the following describes different operation states during the movement of the knob structure 100 and the transmission structure 200.
According to the embodiment of the present disclosure, in the first working state, the knob structure 100 can drive the transmission structure 200 to move, including: in the first working state, during the rotation of the body 110, the body 110 drives the rolling member 130 to move, and the rolling member 130 contacts with the first gear 210 under the elastic action of the elastic member 120 and can drive the first gear 210 to move.
In the embodiment of the present disclosure, in the first working state, the rotation knob structure 100 drives the transmission structure 200 to move, so as to implement the adjusting function of the mechanical structure 10 in the embodiment of the present disclosure. Specifically, in the first working state, by rotating the body 110 of the knob structure, during the rotation of the body 110, the body 110 drives the rolling members 130 to move through the limiting structures 140, for example, the rolling members 130 disposed in the grooves of the two limiting structures 140 are driven to rotate by the rotation of the limiting structures 140. In the process of rotation of the rolling element 130, the rolling element 130 is in contact with the first gear 210 under the elastic action of the elastic element 120, that is, the rolling element 130 is disposed in the tooth slot of the first gear 210, and under the elastic action of the elastic element 120, the rolling element 130 is always disposed in the tooth slot of the first gear 210 in the first working state (that is, not separated from the tooth slot of the first gear), and in the process of rotation of the rolling element 130, the rolling element 130 can drive the first gear 210 to rotate, that is, the rolling element 130 pushes the tooth of the first gear 210, so that the first gear 210 rotates, and then the rotation of the first gear 210 drives the second gear 220 to rotate, and the second gear 220 drives the rack 230 to move, thereby implementing the size adjustment movement of the mechanical structure 10 according to the embodiment of the present disclosure in the first working state.

In the embodiment of the present disclosure, in the second operating state, the rotating knob structure 100 will not drive the transmission structure 200 to move any more, that is, when the rotating knob structure 100 is continuously rotated in the second operating state, the knob structure 100 will rotate relative to the transmission structure 200, so as to implement the function of automatically stopping the adjustment of the mechanical structure 10 in the embodiment of the present disclosure. Specifically, in the second working state, by rotating the body 110 of the knob structure, during the rotation of the body 110, the body 110 drives the rolling members 130 to move through the limiting structures 140, for example, the rolling members 130 disposed in the grooves of the two limiting structures 140 are driven to rotate by the rotation of the limiting structures 140. During the rotation of the rolling element 130, the rolling element 130 will push the elastic element 120 away, so as to deform the elastic element 120, and the rolling element 130 has no elastic action of the elastic element 120, and the rolling element 130 disposed in the tooth space of the first gear 210 will move from one tooth space of the first gear 210 to the next tooth space in sequence (the rolling element 130 moves along the circumferential direction of the first gear 210, and the rolling element 130 does not push the teeth of the first gear 210 to move any more), that is, the rolling element 130 does not rotate the first gear 210 during the rotation, and then the first gear 210 does not rotate in the second working state, so that the second gear 220 and the rack 230 do not move any more, thereby implementing the automatic stop adjustment function of the mechanical structure 10 according to the embodiment of the present disclosure in the second working state.
