As shown in fig. 2, in the embodiment of the present application, the first structure 210 and the second structure 220 are connected by a connecting structure, i.e., the first structure 210 and the second structure 220 are both connected to the connecting structure. The connecting structure includes a first shaft 240, a connecting body 230, a second shaft 250 and an elastic member 260. The first rotating shaft 240 and the second rotating shaft 250 are respectively connected to the connecting body 230, the connecting body 230 is used to keep the relative positions of the first rotating shaft 240 and the second rotating shaft 250 fixed, the connecting body 230 is rotatably connected to the first structure 210 through the first rotating shaft 240, that is, the connecting body 230 and the first structure 210 can rotate relatively, and the axis of rotation is the axis around the first rotating shaft 240. Specifically, the first structure 210 may be rotatably connected to the first rotating shaft 240 by using the axis of the first rotating shaft 240 as a rotating axis, or may be fixedly connected to the first rotating shaft 240; in a state where the first structure 210 is rotatably connected to the first rotating shaft 240, the connecting body 230 may be rotatably connected to the first rotating shaft 240 with an axis of the first rotating shaft 240 as a rotating axis, or may be fixedly connected to the first rotating shaft 240; in a state where the first structure 210 is fixedly connected to the first rotating shaft 240, the connecting body 230 needs to be rotatably connected to the first rotating shaft 240 with an axis of the first rotating shaft 240 as a rotating axis. The connecting body 230 is rotatably connected to the second structure 220 through the second shaft 250, that is, the connecting body 230 and the second structure 220 can rotate relatively, and the axis of rotation is about the second shaft 250. Specifically, the second structure 220 may be rotatably connected to the second rotating shaft 250 by using the axis of the second rotating shaft 250 as a rotating axis, or may be fixedly connected to the second rotating shaft 250; in a state that the second structure 220 is rotatably connected to the second rotating shaft 250, the connecting structure may be rotatably connected to the second rotating shaft 250 by using the axis of the second rotating shaft 250 as a rotating axis, or may be fixedly connected to the second rotating shaft 250; in a state where the second structure 220 is fixedly connected to the second rotating shaft 250, the connecting body 230 needs to be rotatably connected to the second rotating shaft 250 by using the axis of the second rotating shaft 250 as a rotating axis.
As shown in fig. 2, in the embodiment of the application, since the second structure 220 is connected to the connecting body 230 through the second rotating shaft 250, that is, under the condition that the relative position between the second structure 220 and the connecting body 230 is kept fixed, the connecting body 230 rotates around the first rotating shaft 240 relative to the first structure 210 to drive the second structure 220 to rotate around the first rotating shaft 240 relative to the first structure 210, that is, the angle between the first structure 210 and the second structure 220 can be changed by controlling the connecting body 230 to rotate relative to the first structure 210, that is, the opening or the storage of the AR glasses 100 can be controlled. Of course, during the rotation of the connecting body 230 relative to the first structure 210, the second structure 220 can also rotate relative to the connecting body 230, in which state the second structure 220 does not rotate around the first rotation axis 240 relative to the first structure 210.
As shown in fig. 3, in the embodiment of the present application, the connecting body 230 is provided with a first limiting portion 231 for abutting against the first structure 210, and in a state where the first limiting portion 231 abuts against the first structure 210, the connecting body 230 cannot rotate continuously in the first direction around the first rotation axis relative to the first structure 210 (as shown in fig. 6), that is, the first limiting portion 231 limits the rotation of the connecting body 230 relative to the first structure 210 in the first direction, that is, in a state where the AR glasses 100 are opened, the angle between the first structure 210 and the connecting body 230 cannot be increased continuously, so as to ensure that in a state where the AR glasses 100 are worn by a user, the angle between the first structure 210 and the connecting body 230 is kept fixed, and the temple 120 connected to the second structure 220 at the angle can exert a clamping force on the head of the user. Specifically, the first position-limiting portion 231 may be a plane, and the first position-limiting portion 231 is attached to the first structure 210 in a state where the first position-limiting portion 231 abuts against the first structure 210, so as to reduce stress concentration. Of course, the first position-limiting portion 231 may also be a curved surface, and only needs to be able to abut against the first structure 210 to prevent the connecting body 230 from rotating continuously along the first direction relative to the first structure 210.
As shown in fig. 2 and 4, in the embodiment of the present application, an elastic member 260 is further disposed between the second rotating shaft 250 and the second structure 220, and the elastic member 260 provides a restoring force for the second structure 220 to rotate relative to the connecting body 230, so as to ensure that an angle between the second structure 220 and the connecting body 230 is kept fixed without an external force; and ensures that the temples 120 fixedly coupled with the second structure 220 can apply a sufficient grip force to the user's head in case the user wears the AR glasses. Specifically, one end of the elastic member 260 is connected to the second shaft 250, and the other end is connected to the second structure 220. The connection of the elastic element 260, the connection body 230 and the second structure 220 may be a fixed connection, or an abutting connection, as long as the elastic element 260 can provide a restoring force for the second structure 220 to rotate relative to the connection body 230. Specifically, in a state where the first position-limiting portion 231 abuts against the first structure 210 and no external force is applied, the included angle between the second structure 220 and the first structure 210 is a first angle (as shown in fig. 6), and at this time, under the action of the elastic member 260, the included angle between the second structure 220 and the first structure 210 is maintained at the first angle; in a state where the first position-limiting portion 231 abuts against the first structure 210, an external force is applied to at least one of the second structure 220 and the connecting body 230, the second structure 220 can rotate relative to the connecting body 230, and in the rotating process, the second structure 220 and the connecting body 230 overcome the elastic force of the elastic element 260 to change the included angle between the second structure 220 and the connecting body 230 from the first angle to another angle (as shown in fig. 7), that is, the second structure 220 and the connecting body 230 drive the elastic element 260 to deform so as to increase the elastic potential energy of the elastic element 260. Under the condition that the external force is removed, the elastic member 260 recovers deformation to drive the second structure 220 and the connecting body 230 to rotate so that the included angle between the second structure 220 and the connecting body 230 is restored to the first angle, that is, the elastic member 260 provides a restoring force for the second structure 220 to rotate relative to the connecting body 230.
The rotation coupling assembling that this application embodiment provided, including first structure, second structure and connection structure, wherein, first structure and second structure all connect in connection structure. The connecting structure comprises a first rotating shaft, a second rotating shaft and a connecting body, the connecting body is connected with the first structure through the rotation of the first rotating shaft shell, namely, the connecting body can rotate relative to the first structure, and the connecting body rotates relative to the first structure in the state that the position of the second structure relative to the connecting body is fixed, so that the second structure can be driven to rotate relative to the first structure. Under the state that first structure is connected in the picture frame and second structure is connected in the mirror leg, contained angle between first structure and the connecting body can be changed into first predetermined angle by initial angle, under first predetermined angle, mirror leg and picture frame can be the open mode, and under this state, owing to have on the connecting body and can restrict connecting body along first direction pivoted first spacing portion for first structure, under mirror leg and picture frame are the open mode, just difficult in order to continue to rotate between connecting body and the first structure to the mirror leg centre gripping is in user's head in order to accomplish and wears. And because user's head can have great condition, connecting body passes through the rotatable and second structural connection of second pivot, and the second structure can take place to rotate for connecting body promptly, under the contained angle between first structure and connecting body was in the state of first predetermined angle promptly, can take place relative rotation between second structure and the connecting body to increase the contained angle between mirror leg and the picture frame. In addition, be connected with the elastic component between second pivot and the second structure, take place under the pivoted state between second structure and the connection body, the contained angle between mirror leg and the picture frame increases, and the elastic component reduces for the contained angle between mirror leg and the picture frame and provides the restoring force to guarantee that the contained angle between mirror leg and picture frame is first predetermineeing the angle or be greater than first predetermineeing under the condition of angle, the mirror leg all can keep adding the holding power so that the user wears to user's head.
As shown in fig. 2 and 4, in some embodiments of the present application, the elastic member 260 may be a torsion spring having three connecting ends, two of the connecting ends are located at two ends of the torsion spring in the direction of the rotation axis, and both of the connecting ends are fixedly connected or abutted to the second structure 220; the other connecting end is located at the middle of the torsion spring in the direction of the rotation axis, and the connecting end is fixedly connected or abutted to the connecting body 230 (as shown in fig. 5). The torsion spring may be sleeved on the second shaft 250, and during the relative rotation between the second structure 220 and the connecting body 230, the deformation of the torsion spring may change to increase or decrease the elastic potential energy. Because the two connecting ends connected to the second structure 220 are located at two ends of the torsion spring in the direction of the rotation axis, and the connecting end connected to the connecting body 230 is located at the middle of the torsion spring in the direction of the rotation axis, in the process of increasing or releasing potential energy, the acting force of the torsion spring on the connecting body 230 and the second structure 220 is in the direction around the rotation axis, so that the bending moment borne by the second rotating shaft 250 can be effectively reduced, and the connecting body 230 and the second structure 220 can be effectively prevented from rotating towards other directions deviating from the direction around the rotation axis. Specifically, the torsion spring may be fixedly connected to the second structure 220 and the connection body 230 by bonding, welding, or the like, or may be fixedly connected to the second structure 220 and the connection body 230 by a fastener, a screw, or the like, or may be abutted to the second structure 220 and the connection body 230 by using the restoring force of the torsion spring itself, and only the second structure 220 and the connection body 230 may drive the torsion spring to deform in the rotating process to increase or decrease the potential energy.
In other embodiments of the present application, the elastic element 260 may also have only two connecting ends, where the two connecting ends are disposed at two ends of the torsion spring in the direction of the rotation axis, one of the connecting ends is fixedly connected to the second structure 220, and the other connecting end is fixedly connected to the connecting body 230, and only in the process of sending the relative rotation between the second structure 220 and the connecting body 230, the torsion spring is driven to deform so as to increase or decrease the potential energy.
In other embodiments of the present application, the elastic member 260 may also be a spring or a leaf spring or other structures with elasticity. In the case that the elastic member 260 is a spring or a spring plate, one end of the spring or the spring plate may be connected to the second structure 220, and the other end of the spring or the spring plate may be connected to the connecting body 230, only when the connection line between the two ends of the spring or the spring plate deviates from the rotation axis of the second structure 220 and the connecting body 230, in the process of rotating the second structure 220 and the connecting body 230, the distance between the portion of the second structure 220 for connecting the spring or the spring plate and the portion of the connecting body 230 for connecting the spring or the spring plate may change, so that the second structure 220 and the connecting body 230 rotate to drive the spring or the spring plate to deform to increase or decrease potential energy, and the spring or the spring plate may be used to provide a restoring force for the second structure 220 to rotate relative to the connecting.
As shown in fig. 6 and 7, in some embodiments of the present application, the connecting body 230 has a second position-limiting portion 232, and the second position-limiting portion 232 is configured to abut against the second structure 220 to limit the second structure 220 from rotating relative to the connecting body 230. Specifically, the second position-limiting portion 232 limits the rotation angle between the second structure 220 and the connecting body 230 within a second predetermined angle, that is, the second structure 220 and the connecting body 230 can rotate around the second rotation axis 250 within a second predetermined angle (e.g., the state in fig. 6 is changed to the state in fig. 7), so as to adapt to a user with a larger head. After the second structure 220 is changed from the state of fig. 6 to the state of fig. 7, the second structure 220 cannot move relative to the connecting body 230 continuously to increase the included angle between the second structure 220 and the connecting body 230, which can ensure that the elastic element 260 can still provide enough elastic force for the connecting body 230 in the state that the included angle between the second structure 220 and the connecting body 230 is small, specifically, the second structure 220 and the connecting body 230 rotate within a preset range, and through the arrangement of the elastic element 260, the restoring force provided by the elastic element 260 in the preset range of relative rotation between the second structure 220 and the connecting body 230 can be approximately the same, so as to prevent that the restoring force provided by the elastic element 260 in the state that the included angle between the second structure 220 and the connecting body 230 is large is too large to ensure that the included angle between the second structure 220 and the connecting body 230 is small, which affects the wearing comfort of the user.
As shown in fig. 4, in some embodiments of the present application, the second position-limiting portion 232 is a surface of the connecting body 230 adjacent to the first position-limiting portion 231, that is, the first position-limiting portion 231 and the second position-limiting portion 232 are different surfaces on the connecting body 230, and the first position-limiting portion 231 and the second position-limiting portion 232 are adjacent to each other, that is, the first position-limiting portion 231 and the second position-limiting portion 232 may be connected with each other or may have a gap therebetween. And opposite ends of the second position-limiting portion 232 are respectively used for abutting against the second structure 220 to limit the rotation of the second structure 220 relative to the connecting body 230 along the first direction and the rotation along the opposite direction of the first direction. Since the surface of the connecting body 230 has a sufficient area, it can contact the second structure 220 with a larger area, so that the surface of the connecting body 230 is used as the second position-limiting part 232, and the structure of the connecting body 230 and the second structure 220 can be effectively prevented from being damaged due to stress concentration. Specifically, the second position-limiting portions 232 may be two planes or two curved surfaces, and when the included angle between the second structure 220 and the connecting body 230 is zero and a second preset angle, the second structure 220 is attached to the second position-limiting portions 232 on the connecting body 230, so that it is only necessary that the second position-limiting portions 232 have a partial region that can limit the rotation of the second structure 220 relative to the connecting body 230 along the first direction, and it is only necessary that another partial region that can limit the rotation of the second structure 220 relative to the connecting body 230 along the opposite direction of the first direction.
As shown in fig. 8 and 9, in some embodiments of the present application, the first structure 210 has a first locking groove 211, the connecting body 230 has a first through hole 233, and the first rotating shaft 240 penetrates through the first locking groove 211 and the first through hole 233. That is, the connecting body 230 is partially disposed in the first slot 211 of the first structure 210, and the first rotating shaft 240 passes through the first structure 210 and the connecting body 230 to rotatably connect the first structure 210 and the connecting body 230. The first structure 210 and the connecting body 230 are limited from moving relative to each other in the axial direction along the first rotating shaft 240, i.e. the relative rotation between the first structure 210 and the connecting body 230 is limited in a plane, so as to ensure the stability of the path of the relative movement between the first structure 210 and the connecting body 230. Optionally, the connecting body 230 may be in transition fit with the first locking groove 211 to ensure that the first locking groove 211 limits the movement of the connecting body 230 and the first structure 210 along the axial direction of the first rotating shaft 240. It should be noted that the opening of the first card slot 211 faces the circumferential direction of the first rotating shaft 240, so that the connecting body 230 can freely rotate around the first rotating shaft 240 without being limited by the first card slot 211.
As shown in fig. 8 and 9, in some embodiments of the present application, the second structure 220 has a second locking groove 221, the connecting body 230 has a second through hole 234, and the second shaft 250 is disposed through the second locking groove 221 and the second through hole 234. That is, the connecting body 230 is partially disposed in the second slot 221 of the second structure 220, and the second shaft 250 passes through the second structure 220 and the connecting body 230 to rotatably connect the second structure 220 and the connecting body 230. The second structure 220 and the connecting body 230 are limited from moving relative to each other along the axial direction of the second rotating shaft 250, i.e. the relative rotation between the second structure 220 and the connecting body 230 is limited in a plane, so as to ensure the stability of the path of the relative movement between the second structure 220 and the connecting body 230. Optionally, the connecting body 230 may be in transition fit with the second card slot 221 to ensure that the second card slot 221 limits the movement of the connecting body 230 and the second structure 220 along the axial direction of the second rotating shaft 250. It should be noted that the opening of the second card slot 221 faces the circumferential direction of the second rotating shaft 250, so that the connecting body 230 can freely rotate around the second rotating shaft 250 without being limited by the second card slot 221.
As shown in fig. 5, in some embodiments of the present application, one end of the elastic member 260 for being fixedly connected to the connecting body 230 is fixedly connected to the first rotating shaft 240, so that the first rotating shaft 240 and the connecting body 230 are fixedly connected. Optionally, the elastic member 260 is sleeved on the second rotating shaft 250, and the elastic member 260 and the second rotating shaft 250 are in interference fit, so that the elastic member 260 can fix the relative positions of the first rotating shaft 240, the second rotating shaft 250 and the connecting body 230, the connecting body 230 is clamped in the first clamping groove 211 to fix the position of the first structure 210 in the axial direction of the first rotating shaft 240, and the connecting body 230 is clamped in the second clamping groove 221 to fix the position of the second structure 220 in the axial direction of the second rotating shaft 250, so that the relative positions of the first structure 210, the second structure 220, the connecting body 230, the first rotating shaft 240 and the second rotating shaft 250 in the axial direction of the first rotating shaft 240 are fixed, thereby reducing the possibility of mutual separation between different structures and ensuring the stability of the overall structure.
As shown in fig. 9, in some embodiments of the present application, the first through hole 233 is spaced apart from the second through hole 234. Since the first through hole 233 is used for the first rotating shaft 240 to be inserted and the second through hole 234 is used for the second rotating shaft 250 to be inserted, the first through hole 233 and the second through hole 234 are spaced apart, that is, the first rotating shaft 240 and the second rotating shaft 250 are spaced apart. So as to facilitate the arrangement of the first and second rotating shafts 240 and 250 in space. The axis of the first through hole 233 is parallel to the axis of the second through hole 234, i.e. the axes of the first rotating shaft 240 and the second rotating shaft 250 are parallel, so that the moving track of the first structure 210 rotating around the axis of the first rotating shaft 240 and the moving track of the second structure 220 rotating around the axis of the second rotating shaft 250 are in the same plane.
In other embodiments of the present application, the first through hole 233 and the second through hole 234 may be the same through hole, that is, the first rotating shaft 240 and the second rotating shaft 250 may be the same rotating shaft, and it is only necessary that the first structure 210 can rotate around the rotating shaft relative to the connecting body 230, and the second structure 220 can also rotate around the rotating shaft relative to the connecting body 230.
As shown in fig. 2, in some embodiments of the present application, the second structure 220 is formed with a recess for receiving a portion of the connection body 230. Specifically, the distance between the two ends of the second limiting portion 232 far away from the second rotating shaft 250 and the second rotating shaft 250 is within a preset distance, optionally, the preset distance may be 5-20 mm, so as to ensure that the second limiting portion 232 and the second structure 220 can bear a large torque with a small stress. The connecting body 230 is partially disposed in the groove, and the connecting body 230 can be at least partially limited in the groove during the relative rotation with the second structure 220, so as to ensure the stability of the relative rotation path between the connecting body 230 and the second structure 220.
As shown in fig. 4, the first position-limiting portion 231 is an end surface of a portion far from the connection body 230, and since the end surface of the connection body 230 has a sufficient area, the connection body 230 can contact the first structure 210 with a larger area, so that the end surface of the connection body 230 is used as the first position-limiting portion 231, and the structure of the connection body 230 and the first structure 210 can be effectively prevented from being damaged due to stress concentration. Specifically, the first position-limiting part 231 is an end surface of a portion of the connection body 230 close to the first structure 210. In the process that the connecting body 230 rotates relative to the first structure 210, the first position-limiting portion 231 abuts against the first structure 210 to limit the continuous rotation between the first structure 210 and the connecting body 230 along the first direction.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
