Description

Technical Field

[0001] The present application relates to the technical field of wearable device structure, and in particular to a wearable device and a rotating shaft assembly thereof. Background Art

[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 are equipped with optical machines, which project image information onto the lenses of the glasses or a dedicated display screen to achieve intelligence. With the continuous development and popularization of smart glasses, more and more electronic devices are integrated in smart glasses, and the functions realized are becoming more and more comprehensive, so that more and more individual users have begun to use smart glasses and wear them to go out for work or socializing.

[0003] Usually, the temples of smart glasses can be rotated and folded with the frame to facilitate users to store the smart glasses. The hinge structure in the glasses plays an important role in the experience of the glasses. In the conventional technical solution, the hinge components of wearable devices have complex structures and cannot provide damping rebound force. When the hinge is turned outward, the flexible circuit board will be exposed, making the overall device feel loose, and the feel and appearance are poor. Summary of the invention

[0004] On the one hand, an embodiment of the present application provides a shaft assembly, which includes a first bracket, a second bracket, a rotating member, an elastic member and a pin. The second bracket is connected to the rotating member through the elastic member. The first bracket is provided with a first shaft hole, and the rotating member is provided with a second shaft hole. The pin is inserted into the first shaft hole and the second shaft hole, so that the first bracket and the rotating member can rotate coaxially, and then the first bracket and the second bracket can rotate relative to each other. When the first bracket and the second bracket rotate relative to each other, the elastic deformation of the elastic member changes.

[0005] In addition, an embodiment of the present application provides a wearable device, which includes a first functional part, a second functional part and the rotating shaft assembly described in the above embodiment, wherein the first functional part and the second functional part are respectively connected to the first bracket and the second bracket of the rotating shaft assembly, and the first functional part and the second functional part can rotate relative to each other through the rotating shaft assembly.

[0006] The wearable device and the rotating shaft assembly provided in the present application connect the first bracket and the second bracket through an elastic member and a rotating member, and use the elastic force of the elastic member to press the two brackets together, so that there is a damping feeling when the two brackets rotate relative to each other, thereby improving the product feel and user experience.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The present application embodiment provides a shaft assembly 10, please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of an embodiment of the shaft assembly of the present application, Figure 2 yes Figure 1 The exploded schematic diagram of the shaft assembly is shown. It should be noted that the shaft assembly 10 in the present application can be used in wearable devices including VR glasses, AR glasses, smart watches, etc. The shaft assembly 10 includes a first bracket 100, a second bracket 200, a rotating member 300, an elastic member 400 and a pin 500.

[0024] Specifically, the second bracket 200 is connected to the rotating member 300 through the elastic member 400, the first bracket 100 is provided with a first shaft hole 1101, and the rotating member 300 is provided with a second shaft hole 3201, and the pin 500 is inserted into the first shaft hole 1101 and the second shaft hole 3201, so that the first bracket 100 and the rotating member 300 can rotate coaxially, and then the first bracket 100 and the second bracket 200 can rotate relative to each other. When the first bracket 100 and the second bracket 200 rotate relative to each other, the elastic deformation of the elastic member 400 changes. When the second bracket 200 is located at the first position, the elastic member 400 is in an initial elastic deformation state, so that there is a tension between the second bracket 200 and the rotating member 300, thereby pressing the first bracket 100 and the second bracket 200 together. When the first bracket 100 and the second bracket 200 rotate relative to each other, the elastic deformation of the elastic member 400 increases, and the tension between the first bracket 100 and the second bracket 200 increases, so that the relative rotation of the first bracket 100 and the second bracket 200 generates a damping force, so as to utilize the damping force to reduce the probability of shaking of the first bracket 100 and the second bracket 200 during the rotation process due to the influence of external force, and allow the user to obtain a damping feel during the rotation process.

[0025] Optionally, the elastic member 400 may be made of rubber or alloy material with elastic deformation capability. The first bracket 100, the second bracket 200 and the rotating member 300 may be made of metal or plastic. Further, the elastic member 400 may be a spring, which is located between the second bracket 200 and the rotating member 300 and is stretched. When the first bracket 100 and the second bracket 200 rotate relative to each other, the elastic member 400 is further stretched, thereby generating a damping feeling in the rotation.

[0026] Optionally, please also refer to Figures 3 to 5 , Figure 3 yes Figure 1 The schematic diagram of the structure of the first bracket of the rotating shaft assembly is shown, Figure 4 yes Figure 1 The schematic diagram of the structure of the second bracket of the rotating shaft assembly is shown, Figure 5 yes Figure 1 The first bracket 100 includes a first main body 110 and a first connecting portion 120, and the second bracket 200 includes a second main body 210 and a second connecting portion 220. The first connecting portion 120 and the second connecting portion 220 can be connected to external components.

[0027] The first main body 110 is provided with a protruding portion 111, and the second main body 210 is provided with a butting portion 211. The butting portion 211 can contact the contact surface 112 of the first bracket 100. When the first bracket 100 and the second bracket 200 rotate relative to each other, the butting portion 211 changes from contacting the contact surface 112 to being held by the protruding portion 111. Since the distance from the protruding portion 111 in the first main body 110 to the first rotating shaft hole 1101 is longer than the distance from the contact surface 112 to the first rotating shaft hole 1101, during the rotation process, the butting portion 211 moves away from the second rotating shaft hole 3201 of the rotating member 300, that is, the second bracket 200 moves away from the rotating member 300. Since the second bracket 200 is connected to the rotating member 300 through the elastic member 400, the elastic deformation of the elastic member 400 increases at this time, and the pulling force between the second bracket 200 and the rotating member 300 increases, so that the relative rotation between the first bracket 100 and the second bracket 200 generates a damping force.

[0028] Optionally, the rotating member 300 includes a first end 310 and a second end 320, the second shaft hole 3201 is located on the second end 320, and the first end 310 is connected to the elastic member 400. Further, the abutting top portion 211 is provided with a through hole 2111, the rotating member 300 is penetrated through the through hole 2111, and the first end 310 and the second end 320 are respectively located on both sides of the through hole 2111. The rotating member 300 can slide in the through hole 2111, that is, the rotating member 300 and the second bracket 200 can move relative to each other in the normal direction of the through hole 2111, and the through hole 2111 can play a guiding role and limit the assembly relationship between the rotating member 300 and the second bracket 200, that is, limit the freedom of the two in the non-sliding direction. During the rotation of the second bracket 200 , the rotating member 300 passing through the through hole 2111 can be driven to rotate, and the top portion 211 is supported by the protrusion 111 to generate relative movement with the rotating member 300 and move away from the first rotation axis hole 1101 .

[0029] Optionally, the first bracket 100 is provided with a groove 1102, the second end 320 of the rotating member 300 is located in the groove 1102, and a first shaft hole 1101 is provided on the side wall of the groove 1102, the first shaft hole 1101 can penetrate the side wall of the groove 1102 and communicate with the groove 1102, the second shaft hole 3201 on the second end 320 is coaxially arranged with the first shaft hole 1101, and the pin 500 is simultaneously inserted into the first shaft hole 1101 and the second shaft hole 3201, so that the first bracket 100 and the rotating member 300 can rotate coaxially, and then the first bracket 100 and the second bracket 200 can rotate coaxially.

[0030] Optionally, the number of the grooves 1102 may be two and located at both ends of the first main body 110. Accordingly, the number of the rotating member 300 may also be two, and the second end 320 thereof is respectively placed in the two grooves 1102, and the first end 310 thereof is respectively connected to the two elastic members 400 through the two through holes 2111. In some other embodiments, the number of the grooves 1102, the through holes 2111, the rotating member 300 and the elastic member 400 may also be one or more, and those skilled in the art may make corresponding designs according to the overall structure and the matching relationship, which will not be described in detail here.

[0031] Furthermore, the elastic member 400 is connected to the second connection portion 220 of the second bracket 200. Specifically, the elastic member 400 can be connected to the edge of the second connection portion 220 so that the elastic member 400 has a larger connection distance, so that the elastic member 400 is in an elastic deformation state.

[0032] Optionally, please also refer to Figures 6 to 8 , Figure 6 yes Figure 1 A cross-sectional schematic diagram of the second bracket of the rotating shaft assembly when it is in the first position, Figure 7 yes Figure 1 A cross-sectional schematic diagram of the second bracket of the rotating shaft assembly when it is in the second position, Figure 8 yes Figure 1 The schematic diagram of the structure when the second bracket of the rotating shaft assembly is in the third position. The contact surface 112 includes a first contact surface 1121 and a second contact surface 1122. When the abutting top 211 of the second bracket 200 is in close contact with the first contact surface 1121 of the first bracket 100, the second bracket 200 is in the first position. The second bracket 200 can be rotated to the second position along the first direction X. When the abutting top 211 of the second bracket 200 is in close contact with the second contact surface 1122 of the first bracket 100, the second bracket 200 is in the second position. When the second bracket 200 is in the first position, it can be rotated to the third position along the second direction Y. The rotating shaft assembly 10 in this embodiment can be applied to smart glasses. It can be understood that when the second bracket 200 is in the first position, the smart glasses can be in an open state, when the second bracket 200 is rotated from the first position to the second position in the first direction X, the smart glasses can be in an inward folding state, and when the second bracket 200 is rotated from the first position to the third position in the second direction Y, the smart glasses can be in an outward folding state. Specifically, the first direction X and the second direction Y may be opposite, that is, if the first direction X is a counterclockwise direction, the second direction Y is a clockwise direction.

The raised portion 111 includes a first raised portion 1111 and a second raised portion 1112. When the second bracket 200 rotates from the first position to the second position, the first raised portion 1111 abuts against the top portion 211, and the top portion 211 is pried with the first raised portion 1111 as a lever fulcrum. At this time, the elastic member 400 is further stretched to form an inner folding force. When the second bracket 200 rotates from the first position to the third position, the second raised portion 1112 abuts against the top portion 211, and the top portion 211 is pried with the second raised portion 1112 as a lever fulcrum. At this time, the elastic member 400 is also further stretched to form an outer folding force. Optionally, the first raised portion 1111 and the second raised portion 1112 can be located at both ends of the first contact surface 1121.

[0036] Optionally, the wearable device further includes a flexible circuit board 40, and the first bracket 100 of the shaft assembly 10 is provided with a hollow channel 1103, and the flexible circuit board 40 can pass through the shaft assembly 10 through the hollow channel 1103. During the rotation of the shaft assembly 10, the flexible circuit board 40 can remain completely hidden in the shaft assembly 10 without being exposed, which can protect the flexible circuit board 40 on the one hand and improve the aesthetics of the overall structure on the other hand.

[0037] Further, the wearable device may also include an optical machine 60 and a display unit 70. The optical machine 60 may be disposed on the first functional unit 20 or the second functional unit 30, and is used to modulate the image light to project an image on the display unit 70. The optical machine 60 may be one, two, or multiple. In this embodiment, the optical machine 60 is one and is disposed on the top of the second functional unit 30. In some other implementations, the optical machine 60 may also be disposed inside the second functional unit 30. The display unit 70 is disposed on the first functional unit 20, wherein the display unit 70 may be a semi-transparent and semi-reflective lens. For example, the display unit 70 may transmit visible light except red light and may reflect red light. The image light modulated by the optical machine 60 may use red light. When the image light is projected onto the display unit 70, it is reflected into the human eye. The user can view the content projected by the optical machine 60. At the same time, the non-red visible light in the ambient light can enter the human eye through the display unit 70. The user can view objects in the environment while viewing the content projected by the optical machine 60. In another embodiment, a common lens may be provided on the first functional portion 20, and the display portion 70 is provided on the first functional portion 20 and located in front of the lens to form a display interface independent of the lens, which is not specifically limited herein.
