Description

Technical Field

[0001] The present invention relates to a rotating shaft structure and glasses, and in particular to a rotating shaft structure and glasses applied to virtual reality (VR) or augmented reality (AR) glasses. Background Art

[0002] With the development and popularization of virtual reality (VR) or augmented reality (AR), head-mounted displays are now designed to meet consumers' needs of being able to carry them around. Therefore, the market has gradually introduced the design of glasses that can be folded and reduced in size.

[0003] At present, the following three problems are generally encountered in the design of VR or AR glasses. First, in order to ensure that the user wears them stably, a certain clamping force must be maintained, and the glasses must have the functions of eversion and folding. Therefore, during the operation of eversion and retraction of the temples, the hinge structure needs to have different damping designs and free-stop functions to achieve the normal wearing and storage operation feel. Second, the hinge structure needs to have enough threading space to accommodate soft cables (such as FPC) or wires. Third, when the hinge structure is not rotating, the soft cables, wires or related electronic parts cannot be exposed or have mechanical interference. Summary of the invention

The first accommodating space and the second accommodating space are used to pass the flexible flat cable of the glasses.

[0012] In one embodiment, the second housing has a side wall, the side wall includes a slot cooperating with the positioning column, the slot is communicated with the receiving hole, and the side surface of the positioning column is engaged with the slot.

[0013] In one embodiment, when the first shell and the second shell rotate relative to each other, the annular frame moves along an extending direction parallel to the rotation axis through the positioning column and the guide groove.

[0014] In one embodiment, the guide groove includes an inward-retracted area, an extended area and an outward-turned area, and the extended area is located between the inward-retracted area and the outward-turned area, so that the frame and the temple are at different angles according to the position where the positioning column stops in the guide groove.

[0015] In one embodiment, when the positioning post moves relative to the guiding groove to the deployment area, the positioning post is engaged with the recessed portion.

[0016] In one embodiment, the two retaining walls include an inward-retracted retaining wall, and an inward-retracted area is defined between the inward-retracted retaining wall and the concave portion, and there is a step between the inward-retracted area and the concave portion.

[0017] In one embodiment, the two retaining walls include an outward-turned retaining wall, and an outward-turned area is defined between the outward-turned retaining wall and the recessed portion, and the outward-turned area includes an inclined surface.

[0035] The following will refer to the relevant drawings to illustrate the glasses used for virtual reality or augmented reality according to the embodiments of the present invention, wherein the same elements will be described with the same reference symbols. The various elements in the following embodiments are only used to illustrate their relative relationships and do not represent the proportions or sizes of the actual elements.

Figure 2A and Figure 2B They are Figure 1 A stereoscopic schematic diagram and an exploded schematic diagram of one of the rotating shaft structures 2 in the glasses 1, Figure 3 for Figure 2A A cross-sectional schematic diagram of the rotating shaft structure 2, Figure 4A for Figure 2B Schematic diagram of different viewing angles of the base 216 of the first shell 21 in the rotating shaft structure 2. Figure 4B for Figure 4A An enlarged schematic diagram of area A.

[0037] Please refer to Figures 1 to 4B The glasses 1 include a frame 11, at least one temple 12, and at least one shaft structure 2. The shaft structure 2 is used to connect the frame 11 and the temple 12 of the glasses 1, respectively, and the frame 11 and the temple 12 are suitable for relative rotation through the shaft structure 2. Figure 1The glasses 1 shown include two temples 12 and two oppositely disposed rotating shaft structures 2. Figure 2A It is shown Figure 1 In the glasses 1, the shaft structure 2 located at the lower side is taken as an example. Therefore, the frame 11 and the temples 12 can be relatively rotated by the shaft structure 2 to achieve the purpose of retracting the temples 12, unfolding the temples 12 and turning the temples 12 outward.

[0038] The shaft structure 2 includes a first housing 21, a second housing 22, an annular frame 23, an elastic body 24 and a shaft 25. The first housing 21 is connected to the frame 11, and the second housing 22 is connected to the temple 12. However, this is not limited to the present invention. In different embodiments, the first housing 21 can also be connected to the temple 12, and the second housing 22 can be connected to the frame 11.

[0039] The first shell 21 has a guide groove 211, and the guide groove 211 includes two retaining walls 212a, 212b, and a recess 213 between the retaining walls 212a and 212b. In addition, the first shell 21 of the present embodiment also has a fixing portion 214 facing the annular frame 23, and the guide groove 211 is located at the periphery of the fixing portion 214. In the present embodiment, the first shell 21 is formed by two parts, namely, the upper cover 215 and the base 216 are connected (fixed). In different embodiments, the first shell 21 can also be a single component formed in one piece, which is not limited. Here, the guide groove 211 (retaining walls 212a, 212b, recess 213) and the fixing portion 214 are all located at the inner bottom of the base 216.

[0040] The second housing 22 can be relatively rotatable and matched with the first housing 21 and is arranged correspondingly, and at least a portion of the second housing 22 is located inside the first housing 21. The second housing 22 of this embodiment is also composed of two parts, namely, a body 222 and a bottom cover 223, and the body 222 and the bottom cover 223 are fixed together by a fixing member 224 (such as a screw). Of course, in different embodiments, the second housing 22 can also be a single component formed in one piece, and the present invention is not limited thereto.

[0041] The annular frame 23 is rotatably disposed on the first housing 21 and engaged with the second housing 22. The annular frame 23 has a positioning post 231 extending in the direction of the guide groove 211, the positioning post 231 is correspondingly disposed with the guide groove 211 (and the recess 213), and the positioning post 231 can abut against the guide groove 211 and move relative to the guide groove 211. Here, the shapes and sizes of the positioning post 231 and the guide groove 211 (and the recess 213) match each other, the two can move relative to each other, and the positioning post 231 can move relative to the guide groove 211 between the retaining wall 212a, the recess 213 and the retaining wall 212b. In addition, the annular frame 23 also has an annular body 232, and the positioning post 231 is located on one side of the annular body 232.

[0042] like Figure 2B As shown, the number of the guide grooves 211 of this embodiment is two, and the two guide grooves 211 are located on opposite sides of the periphery of the fixing portion 214. In addition, the number of the positioning posts 231 is also two, and the two positioning posts 231 are located on opposite sides of the annular body 232, and are respectively arranged corresponding to the two guide grooves 211, thereby making the annular frame 23 (positioning posts 231) more stable when moving (rotating) relative to the guide grooves 211.

[0043] The elastic body 24 is disposed in the first shell 21 and the second shell 22, and the two ends of the elastic body 24 are respectively connected to the first shell 21 and the annular frame 23. The elastic body 24 of this embodiment is a spring, the upper end of which is fixed to the upper cover 215 of the first shell 21, and the lower end of the spring is fixed to the annular body 232 of the annular frame 23. Therefore, when the first shell 21 rotates relative to the second shell 22, since both ends of the elastic body 24 are restricted, the elastic body 24 will generate a spring compression force due to the rotation of the first shell 21 relative to the second shell 22.

[0044] The rotating shaft 25 is provided through the first shell 21, the annular frame 23 and the elastic body 24. In the present embodiment, the body 222 of the second shell 22 has a receiving hole 221 located in the first shell 21, the receiving hole 221 is located in the first shell 21, and passes through the body 222 along the extension direction D of the rotating shaft 25, and the receiving hole 221 is overlapped with the first shell 21 in the extension direction D of the rotating shaft 25, and the elastic body 24, the annular frame 23, the fixing portion 214 and the guide groove 211 are all located in the receiving hole 221. Here, the rotating shaft 25 is provided with the fixing hole 221 (body 222), and the rotating shaft 25 passes through the upper cover 215, the elastic body 24 and the annular frame 23 in sequence, so that one end of the rotating shaft 25 is located on the upper cover 215, and the other end of the rotating shaft 25 is fixed to the fixing portion 214 of the base 216, thereby fixing the elastic body 24 and the annular frame 23 in the receiving hole 221. Therefore, the first housing 21 and the second housing 22 can rotate relative to each other through the shaft 25, thereby making the frame 11 and the temples 12 relatively rotate to achieve the operation of retracting, unfolding and turning the temples 12. The shaft 25 of this embodiment is for example but not limited to a screw or a bolt.

[0045] In addition, the body 222 of the second shell 22 of the present embodiment has a side wall 226, and the side wall 226 includes a slot 225 arranged in cooperation with the positioning column 231, the slot 225 is communicated with the accommodating hole 221, and one side of the positioning column 231 of the annular frame 23 is engaged in the slot 225 of the body 222. Therefore, when the second shell 22 rotates relative to the first shell 21 (or the first shell 21 rotates relative to the second shell 22), the second shell 22 (body 222) will simultaneously drive the positioning column 231 (annular frame 23) to rotate relative to the first shell 21 through the slot 225. Since the number of the positioning columns 231 of the present embodiment is two, the number of the slots 225 is also two, and the setting positions correspond to the two positioning columns 231.

[0046] In addition, since the two ends of the elastic body 24 are connected to the upper cover 215 of the first housing 21 and the annular frame 23 (annular body 232), and the positioning column 231 of the annular frame 23 can move relative to the guide groove 211, when the first housing 21 rotates relative to the second housing 22 through the rotating shaft 25, the first housing 21 rotates relative to the annular frame 23 at the same time, so that the positioning column 231 also moves relative to the guide groove 211, and the positioning column 231 can selectively stop at the retaining wall 212a, 212b or the recess 213. In other words, when the first housing 21 and the second housing 22 rotate relative to each other, the first housing 21 rotates relative to the annular frame 23 at the same time, and the positioning column 231 of the annular frame 23 can move relative to the guide groove 211, and the positioning column 231 will be stopped by the retaining wall 212a, 212b, or stopped (positioned) at the recess 213, depending on the angle of relative rotation of the first housing 21 and the second housing 22. In addition, during the rotation process, since the guide groove 211 has a height change, the annular frame 23 also moves along the extension direction D parallel to the rotation axis 25 (ie, moves up and down) through the mutual abutment between the positioning column 231 and the guide groove 211 .

[0047] Please refer to Figure 3 , the glasses 1 of this embodiment may further include a flexible flat cable 13 (or wire), the frame 11 and the temples 12 respectively have electronic components for realizing virtual reality or augmented reality, and the flexible flat cable 13 (or wire) can transmit the electrical signals of these electronic components. In addition, a first accommodation space S1 is provided between the base 216 of the first shell 21 of this embodiment and the side wall 2211 of the accommodation hole 221, and the body 222 of the second shell 22 also has a second accommodation space S2 connected to the first accommodation space S, and the flexible flat cable 13 can be arranged in the first accommodation space S1 and the second accommodation space S2. Therefore, in addition to preventing the flexible flat cable 13 (or wire) of the glasses 1 from being exposed and interfering with the movement of the hinge structure 2, it can also protect the related actuating mechanism of the hinge structure 2 from being easily damaged due to falling.

[0048] Please refer to Figure 2B , Figure 4B And with FIG. 5A to FIG. 7B , to illustrate the details of the movement of the shaft structure 2 when the temple 12 of the glasses 1 of this embodiment is unfolded (normal wearing), retracted and everted. Figure 5A is a schematic diagram of the glasses 1 according to an embodiment of the present invention in the unfolded position (normal wearing position), Figure 5B for Figure 5A A partial three-dimensional perspective view of the rotating shaft structure 2 in the glasses 1, Fig. 6A is a schematic diagram of a pair of glasses 1 in an everted position according to an embodiment of the present invention, Figure 6B for Fig. 6A A partial three-dimensional perspective view of the rotating shaft structure 2 in the glasses 1, Fig. 7A is a schematic diagram of a pair of glasses 1 in a retracted position according to an embodiment of the present invention, Figure 7B for Fig. 7A A partial three-dimensional perspective view of the hinge structure 2 in the glasses 1.

[0049] Please refer to Figure 4B The guide groove 211 may include an inward-retracting area A1, an extended area A2, and an outward-turning area A3, and the extended area A2 is located between the inward-retracting area A1 and the outward-turning area A3, so that the frame 11 and the temple 12 are at different angles according to the position of the positioning column 231 stopping at the guide groove 211. The position of the recess 213 is defined as the extended area A2. In addition, the aforementioned retaining wall may include an inward-retracting retaining wall 212a, and the area between the inward-retracting retaining wall 212a and the recess 213 is defined as the inward-retracting area A1, and there is a step △X between the inward-retracting area A1 and the recess 213, and the step △X is the height difference between the edge of the inward-retracting area A1 and the lowest point of the recess 213. The step △X allows the user to have different damping feelings in the operation when retracting the temple 12, and the temple 12 has a free-stop function.

[0050] In addition, the aforementioned retaining wall may further include an outward-turned retaining wall 212b, and the area between the outward-turned retaining wall 212b and the recessed portion 213 is defined as an outward-turned area A3, and the outward-turned area A3 includes an inclined surface A31. In one embodiment, the angle θ' between the inclined surface A31 and a horizontal plane P is, for example but not limited to, 45 degrees. The design of the outward-turned area A3 can expand the outward-turned angle of the temple 12 to be applied to a larger face shape, and the outward-turned angle can be designed and adjusted according to the size of the face, and is not limited. In one embodiment, the outward-turned angle is, for example but not limited to, 20 degrees.

[0051] Please refer to Figure 2B , Figure 4B And cooperate Figure 5A and Figure 5BAs shown, when the temple 12 is opened from the retracted position to the normal wearing position (the opening angle of the temple 12 is about 90 degrees), the first shell 21 and the second shell 22 form a 180-degree angle ( Figure 4B ). When the temples 12 are opened, the first shell 21 and the second shell 22 will rotate relative to each other. Since the positioning column 231 is engaged with the slot 225 of the body 222, the first shell 21 will also rotate relative to the annular frame 23. At this time, the elastic body 24 will be compressed and the spring compression force generated will be evenly applied to the top of the annular frame 23. At the same time, the bottom end of the positioning column 231 of the annular frame 23 and the guide groove 211 are mutually abutted and can be relatively moved to the expansion area A2, and are engaged (stopped) in the recess 213, so that the user can wear the glasses 1 normally. During this rotation process, the positioning column 231 of the annular frame 23 is also guided by the characteristics of the guide groove 211, so that the annular frame 23 moves up and down along the extension direction D parallel to the rotation axis 25.

[0052] In addition, please refer to Figure 2B , Figure 4B And cooperate Fig. 6A and Figure 6B As shown, when the temple 12 is turned outward when applied to a larger face shape, the angle between the first shell 21 and the second shell 22 will exceed 180 degrees ( Figure 4B The angle θ in the figure is, for example, equal to 200 degrees. During the process of the temple 12 being everted, the second shell 22 (main body 222) drives the positioning column 231 of the annular frame 23 to move from the deployment area A2 along the inclined surface A31 toward the direction of the everted retaining wall 212b, and finally stops at the everted retaining wall 212b, reaching the maximum everted angle. When the positioning column 231 of the annular frame 23 moves relative to the guide groove 211 to the everted area A3 and the user does not apply force to the first shell 21 or the second shell 22, the positioning column 231 will move relative to the guide groove 211 to the deployment area A2 along the inclined surface A31 through the elastic restoring force of the elastic body 24, and stop at the recess 213.

[0053] In addition, please refer to Figure 2B , Figure 4B And cooperate Fig. 7A and Figure 7B As shown, when the temple 12 is retracted from the extended position to the retracted position, the first shell 21 and the second shell 22 form a 90-degree angle ( Figure 4B When the temple 12 is retracted, the second housing 22 (main body 222) drives the positioning post 231 of the annular frame 23 to move from the recess 213 across the step △X along the retracted area A1 toward the inwardly turned retaining wall 212a, and finally stops at the inwardly turned retaining wall 212a to reach the retracted position.

[0054] As mentioned above, in the glasses 1 of the present embodiment, the spring compression force of the elastic body 24 is combined with the annular frame 23 that can move up and down along the extension direction D of the rotating shaft 25, and a positioning column 231 corresponding to the guide groove 211 is introduced into the annular frame 23, and the positioning column 231 can abut against the guide groove 211 and move relative to the guide groove 211. When the first shell 21 and the second shell 22 rotate relative to each other, the first shell 21 also rotates relative to the annular frame 23, and when the annular frame 23 is acted upon by the spring compression force of the elastic body 24, the positioning column 231 of the annular frame 23 abuts against the guide groove 211 and moves relative to the guide groove 211. Through the structural features of the concave portion 213, the step difference △X, the inclined surface A31 and the retaining walls 212a, 212b of the guide groove 211, the glasses 1 can meet the operation feel of unfolding, everting, and retracting, which are conducive to wearing and storage, as well as practical and comfortable functions. In addition, the glasses 1 of this embodiment are also designed with a storage space (S1, S2) between the two shells of the hinge structure 2 for accommodating the flexible flat cable 13 (or electric wire), so that the flexible flat cable 13 (or electric wire) and other related materials of the glasses 1 will not be exposed or have mechanical interference problems, thereby realizing the practical functions required by the head-mounted display.

[0055] In summary, in the hinge structure and glasses used for virtual reality or augmented reality glasses of the present invention, the guide groove of the first shell includes two retaining walls and a recessed portion located between the two retaining walls, and the annular frame is rotatably arranged on the first shell and engaged with the second shell, and a positioning column extends in the direction of the guide groove, and the positioning column can abut against the guide groove and move relative to the guide groove, the two ends of the elastic body are respectively connected to the first shell and the annular frame, and the hinge is passed through the first shell, the elastomer and the annular frame; wherein, when the first shell rotates relative to the second shell through the hinge, the first shell simultaneously rotates relative to the annular frame to move the positioning column relative to the guide groove, and the positioning column can selectively stop at the structural design of the two retaining walls or the recessed portion, so that the glasses of the present invention can meet the operating feel of unfolding, everting, and retracting, which is conducive to wearing and storage, and at the same time achieve practical and comfortable functions.

[0056] In one embodiment of the present invention, a storage space for accommodating a flexible flat cable (or electric wire) is designed between the shell of the hinge structure, so that the flexible flat cable (or electric wire) and other related materials of the glasses will not be exposed or interfere with the mechanism, thereby realizing the practical functions required by the head-mounted display.
