[0002] At present, glasses have become a must-have item for some people, especially for people with myopia. With the advancement and development of science and technology, smart glasses have been derived on the basis of traditional glasses. These smart glasses realize intelligence by setting up optical machines to project image information onto the lenses of the glasses or a dedicated display screen.

[0003] In order to facilitate storage, glasses in the related art usually have a hinge mechanism on the frame so that the temples of the glasses can be folded and stored, and can also be rotated to the angle required by the user. In order to achieve the damping effect during the rotation process, the current hinge mechanisms have complex structures and many parts, resulting in high costs for the hinge mechanisms, complex assembly processes, and difficulty in repairing after a failure. Summary of the invention

The damping member comprises a first connecting end, a second connecting end and a deformation portion connected between the first connecting end and the second connecting end, the second connecting end is connected to the second bracket, and the rotating shaft passes through the first bracket and the first connecting end, so that the second bracket can rotate relative to the first bracket, and during the relative rotation process, the deformation portion is driven to deform.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] In order to facilitate storage, glasses in the related art usually have a rotating shaft mechanism on the frame, so that the temples of the glasses can be folded and stored, and can be rotated to the angle required by the user when wearing. In order to clamp the user's head when wearing, the rotating shaft mechanism needs to have a certain eversion angle when opened, and a certain torsional force when everted. At the same time, the rotating shaft mechanism can also have a certain torsional feel during the folding process, so that it is not easy to collide and generate noise during the folding process. The rotating shaft mechanism in the related art has a complex structure and many parts, which leads to high cost of the rotating shaft mechanism, complex assembly process, and difficulty in repair after failure.

Specifically, the first bracket 110 can at least partially extend into the first inner cavity 42 and be fixed to the frame 40 by means of adhesive, screw connection, etc., the second bracket 130 can at least partially extend into the second inner cavity 51 and be fixed to the temple 50 by means of adhesive, screw connection, etc. The damping member 150 is connected between the first bracket 110 and the second bracket 130, and produces a damping effect during the relative rotation of the first bracket 110 and the second bracket 130.

[0028] Specifically in this embodiment, the first bracket 110 has a first end surface 118 ( Figure 5), the first end face 118 is located on the surface of the first bracket 110 facing the second bracket 130, and the first end face 118 is substantially flat. In the present embodiment, the first bracket 110 may be made of metal material, or other materials, such as plastic, etc., which is not limited in the present embodiment. The first bracket 110 is substantially a plate-like structure, which is suitable for connection with the lens frame 40, specifically, suitable for connection with the extension portion 41 of the lens frame 40. In the present embodiment, a first fixing hole 117 is provided on the first bracket 110, and the first fixing hole 117 is used to connect with the extension portion 41 of the lens frame 40 through a fastener, and the fastener may be, for example, a screw, a rivet, etc. The number of the first fixing holes 117 may be one or more, which is not limited in the present embodiment. In the present embodiment, the number of the first fixing holes 117 is three, and the three first fixing holes 117 are arranged in a triangle, which can improve the connection stability with the lens frame 40.

[0029] The first bracket 110 is also provided with a first connecting plate 113 and a second connecting plate 114. The first connecting plate 113 and the second connecting plate 114 are arranged opposite to each other. A first accommodating groove 115 is formed between the first connecting plate 113 and the second connecting plate 114. The first connecting plate 113 and the second connecting plate 114 are provided with an axial hole 116. The axial hole 116 on the first connecting plate 113 and the axial hole 116 on the second connecting plate 114 can be coaxially arranged accordingly.

[0030] The first end surface 118 is formed on the surface of the first connecting plate 113 facing the second bracket 130 and the surface of the second connecting plate 114 facing the second bracket 130, wherein the surface of the first connecting plate 113 facing the second bracket 130 and the surface of the second connecting plate 114 facing the second bracket 130 may be coplanarly arranged to ensure assembly stability when abutting against the second bracket 130. Meanwhile, in this embodiment, the surface of the first connecting plate 113 facing the second bracket 130 and the surface of the second connecting plate 114 facing the second bracket 130 may be arranged substantially parallel to the axial direction of the shaft hole 116.

[0031] Please continue reading Figure 2 and Figure 3 The second bracket 130 is used to connect with the temple 50 and can rotate relative to the first bracket 110. The second bracket 130 has a second end surface 138 ( Figure 5), the second end surface 138 is located on the surface of the second bracket 130 facing the first bracket 110, and the second end surface 138 is substantially flat. In this embodiment, the second bracket 130 can be made of metal material, or other materials, such as plastic, etc., which is not limited in this embodiment. The second bracket 130 is substantially a plate-like structure, which is suitable for connecting with the temple 50. Specifically, it is suitable for extending into the second accommodating cavity 51 of the temple 50 and connecting with the temple 50. Specifically, in this embodiment, the second bracket 130 includes a first plate body 131 and a second plate body 132, and the first plate body 131 and the second plate body 132 are connected. The first plate body 131 is located on the side of the second plate body 132 close to the first bracket 110, and the first plate body 131 and the second plate body 132 can be coplanar or form a step, which is not limited in this embodiment. In this embodiment, a step is formed between the second plate body 132 and the first plate body 131 to facilitate the subsequent connection of the first plate body 131 with the damping member 150.

[0032] The second bracket 130 is provided with a third connecting plate 133 and a fourth connecting plate 134, the third connecting plate 133 and the fourth connecting plate 134 are arranged opposite to each other and connected to the first plate body 131, a second receiving groove is formed between the third connecting plate 133 and the fourth connecting plate 134, the second connecting end 152 is embedded in the second receiving groove 135, and the second end surface 138 is formed on the surface of the third connecting plate 133 facing the first bracket 110 and the surface of the fourth connecting plate 134 facing the first bracket 110. When the first end surface 118 and the second end surface 138 abut, the end surface of the first connecting plate 113 facing the second bracket 130 abuts against the end surface of the third connecting plate 133 facing the first bracket 110, and the end surface of the second connecting plate 114 facing the second bracket 130 abuts against the end surface of the fourth connecting plate 134 facing the first bracket 110. In some embodiments, the end surface of the first connecting plate 113 facing the second bracket 130 and the end surface of the third connecting plate 133 facing the first bracket 110 are roughly equal in area and can be completely fitted together, and the end surface of the second connecting plate 114 facing the second bracket 130 and the end surface of the fourth connecting plate 134 facing the first bracket 110 are roughly equal in area and can be completely fitted together.

[0033] In this embodiment, Figure 3As shown, the second bracket 130 is further provided with a second fixing hole 137. Specifically, the second fixing hole 137 is provided in the second plate 132. The second fixing hole 137 is used to connect with the temple 50 through a fastener, and the fastener may be, for example, a screw, a rivet, etc. The number of the second fixing holes 137 may be one or more, which is not limited in this embodiment. In this embodiment, the number of the second fixing holes 137 is three, and the three second fixing holes 137 are arranged in a straight line, which can improve the connection stability with the temple 50.

[0034] Please combine Figure 3 and Figure 4 The damping member 150 includes a first connection end 151, a second connection end 152, and a deformation portion 153 connected between the first connection end 151 and the second connection end 152. The deformation portion 153 can be deformed when driven by an external force, thereby generating a torsion force in the opposite direction to the external force. The first connection end 151 is close to the first bracket 110, and the second connection end 152 is close to the second bracket 130 and connected to the second bracket 130.

[0035] In this embodiment, the first connection end 151 is embedded in the first receiving groove 115, and the first connection end 151 is provided with a mounting hole 154, and the mounting hole 154 is provided corresponding to the shaft hole 116 on the first connection plate 113 and the second connection plate 114, and the rotating shaft 170 is rotatably installed in the shaft hole 116 and the mounting hole 154, so that the first connection end 151 is rotatably connected to the first bracket 110, and the first connection end 151 can rotate relative to the first bracket 110. In this embodiment, the mounting hole 154 is formed by the first connection end 151 winding around into a ring shape. In some other embodiments, the mounting hole 154 can also be directly opened on the first connection end 151, which is not limited in this embodiment.

[0036] Please continue reading Figure 4 , the second connection end 152 is connected to the second bracket 130, and the second connection end 152 can be embedded in the second receiving groove 135. In this embodiment, the first plate body 131 of the second bracket 130 is provided with a connection column 136, and the second connection end 152 is provided with a connection hole 155, and the connection column 136 is embedded in the connection hole 155, so that the second connection end 152 is connected to the second bracket 130. Specifically, the second connection end 152 is configured as a roughly plate-shaped structure and fits with the first plate body 131. The axial direction of the connection hole 155 and the axial direction of the mounting hole 154 can be roughly perpendicular to each other. The connection column 136 is provided on the first plate body 131 and extends toward the second connection end 152, and is embedded in the connection hole 155.

[0037] To facilitate assembly, the aperture of the connecting hole 155 can be configured to be larger than the outer diameter of the connecting column 136. In this way, during the assembly process, the connecting column 136 can be more easily embedded in the connecting hole 155. Since the aperture of the connecting hole 155 is larger than that of the connecting column 136, when the deformation portion 153 undergoes tensile deformation, the connecting column 136 can be displaced relative to the connecting hole 155. Under the action of the same external force, the slippage generated between the connecting column 136 and the connecting hole 155 can weaken the deformation amplitude of the deformation portion 153 and reduce the deformation torque. In this way, the user can generate torque to form a twisting feel when using it, and can reduce the size of the torque, thereby reducing the clamping feeling on the head and providing a better user experience.

[0038] The deformation portion 153 is used to deform when subjected to external force to form a deformation space between the first bracket 110 and the second bracket 130, so that the first bracket 110 and the second bracket 130 can overcome the resistance force between each other and rotate relative to each other. At the same time, the deformation force generated when the deformation portion 153 is deformed will cause the first bracket 110 and the second bracket 130 to generate a twisting feel during the relative rotation process.

[0039] The deformation part 153 can adopt a variety of structures, such as a spring structure, a torsion spring structure, an elastic rubber structure, etc., which is not limited in this embodiment. In this embodiment, the deformation part 153 is a spring sheet, and the spring sheet can be made of metal. The spring sheet has excellent elastic properties, can be deformed when subjected to external force, and quickly return to its original shape after the external force is removed. As a more specific embodiment, the deformation part 153, the first connecting end 151 and the second connecting end 152 can be combined by integral molding, which can reduce the assembly cost, while enhancing the structural strength of the damping member 150 and improving the tensile resistance.

[0040] In this embodiment, Figure 4 As shown, the deformation part 153 includes a first spring piece 1531 and a second spring piece 1532, the first spring piece 1531 and the second spring piece 1532 are arranged opposite to each other, one end of the first spring piece 1531 is connected to the first connection end 151, and the other end is connected to the second spring piece 1532, and the end of the second spring piece 1532 away from the first spring piece 1531 is connected to the second connection end 152. The deformation part 153 forms a roughly U-shaped structure, and the advantage of this structure is that the deformation range is large, and a large deformation amplitude can be provided, while bringing better elastic performance, and can quickly restore the deformation after the external force disappears. It can be understood that in some other embodiments, the deformation part 153 can also be configured as a Z-shape, a snake shape, etc., which is not limited in this embodiment.

[0041] The working principle of the rotating shaft mechanism 100 provided in this embodiment is as follows:

[0042] See also Figure 5 When the hinge mechanism 100 is in the open state, the first end face 118 of the first bracket 110 and the second end face 138 of the second bracket 130 abut against each other. At this time, point A is the contact point between the first bracket 110 and the second bracket 130, so that the first bracket 110 and the second bracket 130 remain relatively stable. At this time, the damping member 150 is in a natural state and is not subject to external force, so the deformation portion 153 does not deform.

[0043] See also Figure 6 , when the shaft mechanism 100 is folded inwards ( Figure 6 When the first bracket 110 and the second bracket 130 rotate relative to each other with point B as the axis, the first bracket 110 and the second bracket 130 rotate relative to each other with point C as the fulcrum due to the deformation part 153 having deformation ability, and the damping member 150 is stretched to complete the rotation and folding process. During this process, since the distance between points AB is smaller than the distance between points BC, the deformation part 153 of the damping member 150 is always in a stretched state and continuously generates deformation force, so that the relative rotation process of the first bracket 110 and the second bracket 130 can maintain a twisting feel, thereby avoiding the collision between the temple 50 and the frame 40 due to the first bracket 110 and the second bracket 130 rotating too fast during the folding process, causing damage and noise.

[0044] See also Figure 7 When the user wears the glasses, the user's head exerts an outward force on the temple 50, causing the rotating shaft mechanism 100 to turn outward, and the first bracket 110 and the second bracket 130 rotate relative to each other with point B as the axis. Since the deformation part 153 has the ability to deform, the first bracket 110 and the second bracket 130 rotate with point D as the fulcrum, stretching the damping member 150 and completing the outward folding process. In this process, since the distance between points AB is smaller than the distance between points BD, the deformation part 153 of the damping member 150 will always be in a stretched state, continuously generating a deformation force, which means that the first bracket 110 and the second bracket 130 are always affected by the deformation force of the damping member 150, and the first bracket 110 and the second bracket 130 always have the ability to recover to the original state. Figure 5 The tendency of the state shown enables the temple 50 to clamp the user's head and maintain a stable wearing state.

[0045] It should be noted that, when the first bracket 110 and the second bracket 130 are folded or unfolded, the first end surface 118 of the first bracket 110 and the second end surface 138 of the second bracket 130 can both maintain an abutting contact state at at least one point.

[0046] The hinge mechanism 100 provided in this embodiment can be applied to a frame 30, glasses 10 or smart glasses. The first end face 118 of the first bracket 110 and the second end face 138 of the second bracket 130 are in contact with each other. When the first bracket 110 and the second bracket 130 are in an open state, the first end face 118 and the second end face 138 can be completely in contact with each other to ensure the stability of the hinge mechanism 1100. By providing the damping member 150, during the relative rotation of the first bracket 110 and the second bracket 130, the first end face 118 of the first bracket 110 and the second end face 138 of the second bracket 130 can rotate with each other because the deformation part 153 can be deformed. When the first bracket 110 and the second bracket 130 are in a folded state or an everted state, the deformation part 153 can be deformed, so that a pulling force can be formed between the first bracket 110 and the second bracket 130 to generate a twisting feel. The entire hinge mechanism 100 has a small number of parts, low assembly difficulty and low cost.

[0047] In another embodiment, Figure 8 As shown, the glasses 10 may also be smart glasses, which may include a frame 30, a display unit 70, and an optical engine 60. The structure of the frame 30 may refer to the aforementioned content and will not be repeated here.

[0048] The optical machine 60 is arranged on the temple 50 and is used to modulate the image light to project the image on the display unit 70. The optical machine 60 can be various types of optical machine 60 systems, which are not specifically limited here. The optical machine 60 can be one, two, or multiple. In this embodiment, there is one optical machine 60, which is arranged on one temple 50 and loaded on the top of the temple 50. The display unit 70 is arranged on the frame 40, wherein the display unit 70 can be a semi-transparent and semi-reflective lens 20. For example, the display unit 70 can transmit visible light except red light and can reflect red light. The image light modulated by the optical machine 60 can use red light. When the image light is projected onto the display unit 70, it is reflected into the human eye. The user can see the content projected by the optical machine 60. At the same time, the visible light other than red light in the ambient light can enter the human eye through the display unit 70. The user can see the objects in the environment while watching the content projected by the optical machine 60. In another embodiment, a common lens 20 may be disposed on the frame 40, and the display unit 70 is disposed on the frame 40 and located in front of the lens 20, forming a display interface independent of the lens 20. No specific limitation is made herein.

[0049] It should be noted that the smart glasses 10 provided in this embodiment can be smart glasses 10 based on virtual reality technology (Virtua lRea l ity, VR), which is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment so that users can immerse themselves in the environment. Virtual reality technology uses data from real life, electronic signals generated by computer technology, and combines them with various output devices to transform them into phenomena that people can feel. These phenomena can be real objects in reality, or substances that are invisible to our naked eyes, which are expressed through three-dimensional models.

[0050] It can also be a smart glasses 10 based on augmented reality (AR) technology, which is a technology that cleverly integrates virtual information with the real world and superimposes virtual display content on the real scene. It generates virtual information such as visual images, sounds, etc. through computer technology; then applies the virtual information to the real world. Virtual reality technology not only displays real-world information, but also can display virtual information at the same time, and the two types of information complement and overlap each other.

[0051] It can also be a smart glasses 10 based on mixed reality (MR) technology, which introduces real scene information into the virtual environment, builds an interactive feedback information loop between the virtual world, the real world and the user, so as to enhance the realism of the user experience.
