Description

Temple connection structure and head-mounted display device

[0001] This application claims priority to Chinese Patent Application No. 2025100381942, filed on January 9, 2025, entitled "Temple Connection Structure and Head-Mounted Display Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of head-mounted display technology, and in particular to a temple connection structure and a head-mounted display device. Background Technology

[0003] Current head-mounted display devices are evolving towards lighter weight and smaller size to reduce weight and improve wearing comfort. As a result, temples are being designed to be increasingly thinner. The hinge structure, as the connection between the temple and the frame, is usually located inside the temple. However, because the hinge structure itself cannot be further thinned, especially the structure around the axis of rotation, it is difficult to further reduce its thickness and optimize its design, making it difficult to adapt to devices with ultra-thin temples. Therefore, designing a hinge structure that can accommodate ultra-thin temples is a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0004] The main objective of this application is to propose a temple connection structure and a head-mounted display device, which aims to enable the hinge structure to be adapted to ultra-thin temples.

[0005] To achieve the above objectives, this application proposes a temple connection structure for connecting the temples and the frame, the temple connection structure comprising:

[0006] A first support, wherein the axis of rotation of the first support is located outside the temple of the mirror;

[0007] A second bracket, rotatably connected to the first bracket, wherein one of the first bracket and the second bracket is mounted on the temple and the other is mounted on the frame; and

[0008] An elastic element, which connects the first bracket and the second bracket, first increases and then decreases in elastic deformation during the unfolding process of the temple from the folded position to the open position.

[0009] In one embodiment, the first bracket is disposed on the inner side of the temple, and when the temple is in the folded position, the rotation axis of the first bracket is located on the side of the temple closer to the frame.

[0010] In one embodiment, the inner side of the temple is provided with a mounting groove, the first bracket includes a mounting base and a connecting bracket connected to each other, the mounting base is disposed in the mounting groove, and the portion of the connecting bracket extending out of the mounting groove is rotatably connected to the second bracket.

[0011] In one embodiment, the first bracket is provided with a first guide surface, and the second bracket is provided with a first sliding protrusion. The first sliding protrusion slides against the first guide surface. During the unfolding process of the temple from the folded position to the open position, the distance between the first guide surface and the rotation axis of the first bracket first increases and then decreases, so that the elastic deformation of the elastic element first increases and then decreases.

[0012] In one embodiment, the first bracket includes a mounting base and a connecting bracket. The mounting base is disposed on the temple and has the first guide surface. The connecting bracket includes a first rotating part and a sliding part fixed on the first rotating part. The first rotating part is rotatably connected to the second bracket. The sliding part is slidably disposed on the mounting base. The elastic element is connected between the sliding part and the mounting base.

[0013] In one embodiment, the mounting base is provided with a first protrusion, the first protrusion is provided with a sliding hole, the sliding part is slidably disposed through the sliding hole, and the elastic element is disposed between the first protrusion and the end of the sliding part that extends out of the sliding hole.

[0014] In one embodiment, the mounting base is further provided with two opposing second protrusions, and the connecting bracket further includes a sliding plate portion. The sliding plate portion is disposed at one end of the sliding portion that protrudes from the sliding hole, and the opposite sides of the sliding plate portion slide against the two second protrusions respectively; one end of the elastic member abuts against the sliding plate portion, and the other end abuts against the first protrusion.

[0015] In one embodiment, the elastic element is configured as a compression spring, and during the unfolding process of the temple from the folded position to the open position, the compression of the elastic element first increases and then decreases.

[0016] In one embodiment, when the temple is in the open position, the elastic potential energy of the elastic element is not zero.

[0017] In one embodiment, the mounting base includes a base plate portion and two first plate portions disposed on opposite sides of the base plate portion. The plate surface of the base plate portion is arranged parallel to the rotation axis of the first bracket, and the first plate portion is provided with a first guide surface on the side near the second bracket.

[0018] In one embodiment, the second bracket includes a mounting portion and a rotating portion connected to each other. The mounting portion is disposed on the frame, and the second rotating portion is rotatably connected to the first rotating portion. The second rotating portion forms a first convex ridge between two intersecting sides, and the first convex ridge is configured as a first sliding convex ridge.

[0019] In one embodiment, the mounting base further includes a second plate portion connecting the two first plate portions, the second plate portion, the first plate portion, and the base plate portion together enclosing a receiving cavity, and the sliding portion and the elastic element are disposed within the receiving cavity.

[0020] In one embodiment, two first rotating parts are provided, and the connecting bracket further includes a baffle part connecting the two first rotating parts. The baffle part is used to block the gap between the second plate part and the first rotating part, and / or the gap between the second plate part and the first rotating part.

[0021] In one embodiment, the temple connection structure further includes a shielding member extending about the rotation axis of the first bracket and used to shield the axial gap between the two first rotating parts.

[0022] In one embodiment, the first bracket or the temple is provided with a second sliding protrusion, and the second bracket is provided with a second guide surface. During the unfolding process of the temple from the open position to the outward limit position, the second sliding protrusion slides against the second guide surface, and the distance between the second sliding protrusion and the rotation axis of the first bracket decreases, so as to increase the elastic deformation of the elastic element.

[0023] In one embodiment, the temple has a second ridge formed between its end face and a side face away from the axis of rotation of the first support, the second ridge being configured as a second sliding ridge.

[0024] In one embodiment, the second bracket includes a mounting portion and a rotating portion connected to each other. The mounting portion is disposed on the mirror frame, and the second rotating portion is rotatably connected to the first bracket. The second guide surface is disposed on the end face of the mounting portion near the first bracket.

[0025] This application also proposes a head-mounted display device, including a frame, temples, and the aforementioned temple connection structure, wherein the temples are mounted on the frame via the temple connection structure.

[0026] In the technical solution of this application, the first bracket and the second bracket together serve as the hinge structure between the temple and the frame. By rotatably connecting the portion of the first bracket protruding from the temple to the second bracket, that is, by setting the structure around the axis of rotation on the outside of the temple, compared with the prior art, the temple no longer needs to completely cover this part of the structure, thereby removing the limitation on the thickness of the temple and allowing the temple to be made thinner. In other words, the temple connection structure of this embodiment can be adapted to ultra-thin temples. Secondly, by the change of elastic potential energy of the elastic element, the temple can have a self-returning function during unfolding and folding operations, thereby improving its ease of operation.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0047] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0048] This application proposes a temple connection structure for connecting the temples and frames of eyeglasses, such as the temples of head-mounted display devices, which can be mounted on the frames via this temple connection structure. Head-mounted display devices include, but are not limited to, AR glasses, VR glasses, and MR glasses. Taking AR glasses as an example, their frames typically have a display module to provide image information to the user's eyes.

[0049] It should be noted that as the temples gradually unfold from the folded state, they successively pass through the folded position, the open position, and the outward-folding limit position. When in the folded position, the free end of the temple is adjacent to or abuts the frame. When in the open position or the outward-folding limit position, the free end of the temple is away from the frame. The temples have multiple wearing states from the open position to the outward-folding limit position to allow users with different head sizes to wear them normally and improve user wearing comfort.

[0050] Please refer to Figures 1 to 3. In one embodiment of this application, the temple connection structure includes a first bracket 100 and a second bracket 200. The second bracket 200 is rotatably connected to the first bracket 100. One of the first bracket 100 and the second bracket 200 is installed on the temple 500, and the other is installed on the frame 600.

[0051] Specifically, in this embodiment, the first support 100 is disposed on the temple 500, and the second support 200 is disposed on the frame 600. For ease of writing and explanation, this embodiment will be used as the basis for the following description. Of course, it can be understood that in other embodiments, the first support 100 may be disposed on the frame 600, and the second support 200 on the temple 500.

[0052] Current head-mounted display devices are evolving towards lighter weight and smaller size to reduce weight and improve wearing comfort. As a result, the temples 500 are being designed to be increasingly thinner. The hinge structure, serving as the connection between the temples 500 and the frame 600, is typically located inside the temples 500. However, because the hinge structure itself cannot be further thinned, especially the structure surrounding the rotation axis, it is difficult to further reduce its thickness and optimize its design, making it unsuitable for devices with ultra-thin temples 500. Therefore, designing a hinge structure that can accommodate ultra-thin temples 500 is a pressing technical problem that needs to be solved in this field.

[0053] To address the aforementioned issues, please refer to Figures 1 and 2. In one embodiment, optionally, the rotation axis of the first support 100 is located outside the temple 500. That is, in this embodiment, the portion of the first support 100 protruding from the temple 500 is rotatably connected to the second support 200. Thus, the first support 100 and the second support 200 together serve as a hinge structure between the temple 500 and the frame 600. By arranging this structure around the rotation axis on the outside of the temple 500, compared to the prior art, the temple 500 no longer needs to completely cover this part of the structure, thereby removing the limitation on the thickness of the temple 500 and allowing the temple 500 to be made thinner. In other words, the temple connection structure of this embodiment can be adapted to ultra-thin temples 500.

[0054] Referring to Figure 2, optionally, the first bracket 100 is located on the inner side of the temple 500. When the temple 500 is in the folded position, the axis of rotation of the first bracket 100 is located on the side of the temple 500 closer to the frame 600. That is, the axis of rotation of the first bracket 100 is located on the inner side of the temple 500. This avoids the problem of the structure of the first bracket 100 being exposed on the outer side of the temple 500, resulting in an untidy and aesthetically pleasing appearance of the device, and also makes the temple connection structure more compact. Of course, in other embodiments, the axis of rotation of the first bracket 100 may also be located on the side away from the frame 600.

[0055] It should be noted that when the head-mounted display device is worn on the user's head, the inner side of the temple 500 refers to the side facing the user's face, and the outer side of the temple 500 refers to the side away from the user's face.

[0056] Referring to Figure 3, further, the inner side of the temple 500 is provided with a mounting groove 501. The first bracket 100 includes a mounting base 110 and a connecting bracket 120 connected together. The mounting base 110 is disposed in the mounting groove 501, and the portion of the connecting bracket 120 extending out of the mounting groove 501 is rotatably connected to the second bracket 200. Thus, the outer side of the temple 500 is exposed as a complete flat or curved surface, improving the aesthetics of the device. Secondly, by installing the mounting base 110 within the mounting groove 501, the connection strength and installation reliability between the first bracket 100 and the temple 500 are improved. Furthermore, by housing part of the structure of the first bracket 100 within the mounting groove 501, the structure of the first bracket 100 exposed outside the temple 500 is made more compact, improving aesthetics. Of course, in other embodiments, the mounting groove 501 may not be provided, and the mounting base 110 may be directly mounted on the inner side of the temple 500.

[0057] Optionally, the mounting base 110 is fixed in the mounting groove 501 by adhesive bonding. Of course, in other embodiments, it can also be fixed in the mounting groove 501 by welding, screws, or rivets.

[0058] Please refer to Figures 4 to 8. In order to improve the convenience of unfolding and folding the temple 500, the temple connection structure also includes an elastic element 300 that connects the first support 100 and the second support 200. During the unfolding process of the temple 500 from the folded position to the open position, the elastic deformation of the elastic element 300 first increases and then decreases.

[0059] Specifically, the temple 500 is defined as having a far-distance position between the folded and open positions. When the temple 500 is in this far-distance position, the elastic deformation of the elastic element 300 reaches its maximum. That is, as the temple 500 unfolds from the folded position towards the far-distance position, the elastic deformation increases until it reaches its maximum value; as the temple 500 unfolds from the far-distance position towards the open position, the elastic deformation begins to decrease from its maximum value.

[0060] In this embodiment, when the user applies an operating force to unfold the temple 500, if the user removes the operating force on the temple 500 at the moment the temple 500 passes the far distance position, the elastic potential energy stored in the elastic element 300 is released, and the first bracket 100 is rotated toward the position corresponding to the open position of the temple 500, so that the temple 500 has the function of automatically returning to the open position during the unfolding process.

[0061] Of course, if the user removes the force applied to the temple 500 during the unfolding process, before the temple 500 has passed a distant position, the temple 500 will automatically return to the folded position under the release of the elastic potential energy of the elastic element 300.

[0062] It can be understood that the folding process of the temple 500 is equivalent to the reverse process of its unfolding process. Therefore, during the folding process of the temple 500 from the open position to the folded position, the elastic deformation of the elastic element 300 first increases and then decreases. That is, the temple 500 also has the function of automatically returning to the folded position during the folding process.

[0063] Thus, in this embodiment, the change in elastic potential energy of the elastic element 300 enables the temple 500 to have a self-returning function during unfolding and folding operations, thereby improving its ease of operation. Of course, in other embodiments, the elastic element 300 may not be provided.

[0064] It is understood that there are multiple ways to achieve the change of elastic potential energy in the elastic element 300. For example, in one embodiment, the first bracket 100 is provided with a first guide surface 101, and the second bracket 200 is provided with a first sliding protrusion 201. The first sliding protrusion 201 slides against the first guide surface 101. During the unfolding process of the temple 500 from the folded position to the open position, the distance between the first guide surface 101 and the rotation axis of the first bracket 100 first increases and then decreases, so that the elastic deformation of the elastic element 300 first increases and then decreases.

[0065] It should be noted that the contact methods between the first sliding protrusion 201 and the first guide surface 101 include, but are not limited to, point contact, line contact, and surface contact. Furthermore, the sliding contact 201 against the first guide surface 101 can mean either that the first sliding protrusion 201 is stationary relative to the frame 600, while the first guide surface 101 moves relative to the frame 600 as the temple 500 rotates; or that the first sliding protrusion 201 moves relative to the frame 600 as the temple 500 rotates, while the first guide surface 101 remains stationary relative to the frame 600.

[0066] In this embodiment, since the first bracket 100 is located on the temple 500, the first sliding protrusion 201 is fixed relative to the frame 600, and the first guide surface 101 rotates together with the temple 500.

[0067] Specifically, when the first sliding protrusion 201 slides relative to the first guide surface 101, it can cause the position of the temple 500 relative to the rotation axis of the first bracket 100 to change, thereby causing the elastic deformation of the elastic element 300 to change.

[0068] It can be understood that the folding process of the temple 500 is equivalent to the reverse process of its unfolding process. Therefore, during the folding process of the temple 500 from the open position to the folded position, the distance between the first guide surface 101 and the rotation axis of the first support 100 will first increase and then decrease, so that the elastic deformation of the elastic element 300 will first increase and then decrease. That is, the temple 500 has the function of automatically returning to the folded position during the folding process.

[0069] Thus, in this embodiment, the first guide surface 101 and the first sliding protrusion 201 cooperate to cause a change in the elastic potential energy of the elastic element 300, enabling the temple 500 to have a self-returning function during unfolding and folding operations, thereby improving its ease of operation. Of course, in other embodiments, the first guide surface 101 and the first sliding protrusion 201 may not be provided, and the change in the elastic potential energy of the elastic element 300 may be achieved through other structural forms. This application does not specifically limit this.

[0070] It should be noted that when the temple 500 is in the open position, the elastic element 300 can be in a compressed or stretched state, that is, the elastic element 300 has a pre-deformation and the initial elastic potential energy of the elastic element 300 is not zero; or the elastic element 300 can be in a natural state, that is, the elastic element 300 has no pre-deformation and the initial elastic potential energy of the elastic element 300 is zero.

[0071] In this embodiment, when the temple 500 is in the open position, the elastic element 300 has a pre-deformation, that is, the elastic potential energy of the elastic element 300 is not zero. On the one hand, this ensures that the first support 100 and the second support 200 can maintain a tight connection and avoids the problem of looseness and wobbling of the temple 500; on the other hand, it makes the rotation operation of the temple 500 have a damped feel, thereby improving the product quality of the device.

[0072] In addition, the meaning of the increase or decrease of the elastic potential energy (i.e. elastic deformation) of the elastic element 300 includes, but is not limited to, the elastic potential energy changing abruptly to a certain value and then remaining basically unchanged, or the elastic potential energy gradually increasing or decreasing, or the elastic potential energy gradually increasing or decreasing to a certain value and then remaining basically unchanged.

[0073] It is understood that the first support 100 can have various structural forms. For example, referring to Figures 9 to 11, in one embodiment, the first support 100 includes a mounting base 110 and a connecting support 120. The mounting base 110 is disposed on the temple 500 and has a first guide surface 101. The connecting support 120 includes a first rotating part 121 and a sliding part 122 fixedly disposed on the first rotating part 121. The first rotating part 121 is rotatably connected to the second support 200, and the sliding part 122 is slidably disposed on the mounting base 110. An elastic element 300 is connected between the sliding part 122 and the mounting base 110. Specifically, the connecting support 120 can rotate about the rotation axis of the first support 100, but will not move in a direction away from or close to the rotation axis; while the mounting base 110, because it can slide relative to the sliding part 122, can move in a direction away from or close to the rotation axis to change the distance between the first guide surface 101 and the rotation axis, and at the same time change the elastic deformation of the elastic element 300. Thus, the structure is simple and easy to implement.

[0074] Of course, in other embodiments, the first bracket 100 may also be in other forms. For example, the first bracket 100 includes a mounting base 110 and a connecting bracket 120. The mounting base 110 is disposed on the temple 500 and is provided with a first guide surface 101. The connecting bracket 120 is rotatably connected to the second bracket 200. The mounting base 110 is also fixedly provided with a pull rod. The connecting bracket 120 is provided with a groove with an elongated hole structure corresponding to the pull rod. One end of the pull rod is provided with a sliding protrusion that can slide in the groove. The elastic element 300 is connected between the mounting base 110 and the connecting bracket 120.

[0075] Referring to Figures 3 and 9, optionally, the mounting base 110 is provided with a first protrusion 111, the first protrusion 111 is provided with a sliding hole 112, the sliding part 122 is slidably disposed in the sliding hole 112, and the elastic member 300 is disposed between the first protrusion 111 and the end of the sliding part 122 that extends out of the sliding hole 112. That is, one end of the elastic member 300 is disposed in the first protrusion 111, and the other end is disposed at the end of the sliding part 122 away from the axis of rotation. In this way, on the one hand, the sliding hole 112 can play a guiding role, so that the sliding part 122 slides more smoothly and stably; on the other hand, the elastic member 300 is disposed between the ends of the first protrusion 111 and the sliding part 122, so that it can also deform smoothly. Of course, in other embodiments, the mounting base 110 may also be provided with a groove, the sliding part 122 may be a slide rail, and the slide rail may be slidably disposed on the groove.

[0076] Referring to Figures 3 and 9, optionally, the mounting base 110 is further provided with two opposing second protrusions 113, and the connecting bracket 120 also includes a sliding plate portion 123. The sliding plate portion 123 is located at one end of the sliding hole 112 of the sliding portion 122, and the opposite sides of the sliding plate portion 123 slide against the two second protrusions 113 respectively. One end of the elastic member 300 abuts against the sliding plate portion 123, and the other end abuts against the first protrusion 111. Optionally, the sliding portion 122 is generally arranged in a rod-like structure. In this way, by cooperating with the sliding plate portion 123 and the second protrusion 113, the smoothness of the sliding of the mounting base 110 relative to the connecting bracket 120 can be further improved, and the installation and fixation of the elastic member 300 can be facilitated. Of course, in other embodiments, the sliding plate portion 123 and the second protrusion 113 may not be provided, and one end of the elastic member 300 may be fixed to the end of the sliding portion 122 by welding or bonding.

[0077] Optionally, the elastic element 300 is configured as a compression spring. During the unfolding process of the temple 500 from the folded position to the open position, the compression of the elastic element 300 first increases and then decreases. This results in a simple and easy-to-implement structure. Specifically, please refer to Figures 8 to 11. In Figure 8, the length L2 of the elastic element 300 is larger than that in Figure 9, approximately equal to that in Figure 10, and larger than that in Figure 11; the length L2 in Figure 11 is the smallest, followed by that in Figure 9. It can be understood that as the elastic element 300 changes from its state in Figure 8 to that in Figure 9, its length L2 decreases, meaning its compression further increases. Similarly, the relationship between the compression of the elastic element 300 and its length L2 in other figures can be understood, and therefore will not be elaborated upon here.

[0078] Of course, in other embodiments, the elastic element 300 may be configured as a tension spring and disposed between the first protrusion 111 and the sliding portion 122 at one end near the axis of rotation.

[0079] Referring to Figures 3 and 4, optionally, the mounting base 110 includes a base plate portion 114 and two first plate portions 115 disposed on opposite sides of the base plate portion 114. The plate surfaces of the base plate portion 114 are arranged parallel to the rotation axis of the first support 100, and the first plate portions 115 are provided with a first guide surface 101 on the side near the second support 200. It should be noted that "parallel" refers to a parallel or nearly parallel state, and "intersecting" refers to a perpendicular or nearly perpendicular state. Thus, two first sliding protrusions 201 are also provided accordingly. By having the two first plate portions 115 slide and abut against the two first sliding protrusions 201 in a one-to-one correspondence, the smoothness and stability of the rotation and movement of the mounting base 110 can be improved. Specifically, in the embodiment where the mounting base 110 is provided with a first protrusion 111 and a second protrusion 113, the first protrusion 111 and the second protrusion 113 are provided on the side of the base plate portion 114 away from the temple 500. Of course, in other embodiments, there may be only one first plate portion 115.

[0080] Referring to Figures 4 to 7, optionally, the second bracket 200 includes a mounting portion 210 and a rotating portion 220 connected together. The mounting portion 210 is disposed on the frame 600, and the second rotating portion 220 is rotatably connected to the first rotating portion 121. The second rotating portion 220 forms a first protruding rib 221 between its two intersecting sides, and the first protruding rib 221 is configured as a first sliding protrusion 201. That is, the first protruding rib 221 can slide against the first guide surface 101 to cause the first guide surface 101 to move in a direction away from or close to the axis of rotation. Of course, in other embodiments, a rib can also be provided on the end face of the second bracket 200 facing the first bracket 100, and the rib can serve as the first sliding protrusion 201.

[0081] Specifically, when the temple 500 is in the folded position, the first guide surface 101 fits against the first side of the first protrusion 221 to limit the extreme position of the first bracket 100 under the folding operation; when the temple 500 is in the unfolded position, the first guide surface 101 fits against the second side of the first protrusion 221 to limit the extreme position of the connecting bracket 120 under the unfolding operation.

[0082] Of course, it is understandable that when the temple 500 flips outward from the unfolded position to the outward limit position, although the connecting bracket 120 of the first bracket 100 no longer moves relative to the second bracket 200, the mounting base 110 of the first bracket 100 can still move relative to the second bracket 200 due to the presence of the elastic element 300.

[0083] Based on this, in this embodiment, optionally, the temple connection structure also includes an elastic element 300 connecting the first support 100 and the second support 200. The elastic element 300 connects the first support 100 and the second support 200. During the unfolding process of the temple 500 from the open position to the outward extreme position, the elastic deformation of the elastic element 300 increases.

[0084] When the temple 500 flips outward from its open position, it causes the elastic element 300 to increase its elastic potential energy. On the one hand, when the user removes the force applied to the temple 500, the elastic element 300 can cause the temple 500 to rotate inward and automatically return to its open position. On the other hand, the elastic force of the elastic element 300 can be converted into a clamping force on the temple 500, thus preventing the temple 500 from slipping off the user's head when wearing the device.

[0085] It is understood that there are various ways to achieve the change of elastic potential energy in the elastic element 300. For example, in one embodiment, the temple 500 is provided with a second sliding protrusion 502, and the second bracket 200 is provided with a second guide surface 202. During the unfolding process of the temple 500 from the open position to the outward extreme position, the second sliding protrusion 502 slides against the second guide surface 202, and the distance between the second sliding protrusion 502 and the rotation axis of the first bracket 100 decreases, so as to increase the elastic deformation of the elastic element 300.

[0086] Specifically, please refer to Figures 8 to 11. In Figure 8, the distance L1 between the second sliding protrusion 502 and the rotation axis of the first support 100 is larger than the distance L1 in Figure 9, and is approximately equal to the distance L1 in Figure 10, and is larger than the distance L1 in Figure 11. The distance L1 in Figure 11 is the smallest, and the distance L1 in Figure 9 is the second largest.

[0087] That is, by utilizing the characteristic that the mounting base 110 can be displaced relative to the second bracket 200, during the outward flipping of the temple 500, the elastic force of the elastic element 300 can cause the second sliding protrusion 502 to remain in contact with the second guide surface 202, so that there is no gap between the outer side of the temple 500 and the frame 600, thereby improving the aesthetics of the device when worn.

[0088] Generally speaking, in order for the temple 500 to achieve the outward tilting function (i.e., the process of unfolding from the open position to the extreme outward tilting position), a certain clearance is usually reserved on the outer side between the temple 500 and the frame 600 to avoid interference during movement. However, this clearance results in a gap between the temple 500 and the frame 600 on the outer side of the device when worn, thus affecting the aesthetics of the product.

[0089] In this embodiment, taking advantage of the characteristic that the mounting base 110 can move relative to the connecting bracket 120 and the second bracket 200, during the process of the temple 500 flipping outward from the open position, the mounting base 110 can move away from the rotation axis while rotating. That is, the temple 500 can move backward while rotating relative to the rotation axis, so that even if no clearance is provided between the temple 500 and the frame 600, the temple 500 can still perform the outward flipping operation as usual.

[0090] Of course, in other embodiments, the first support 100 may be provided with a second sliding protrusion 502, or the second sliding protrusion 502 and the second guide surface 202 may not be provided. Instead, the elastic potential energy change of the elastic element 300 may be achieved through other structural forms. This application does not make specific limitations in this regard.

[0091] Referring to Figures 11 to 13, optionally, the temple 500 has a second protruding rib 503 formed between its end face and the side surface away from the rotation axis of the first support 100. The second protruding rib 503 is configured as a second sliding protrusion 502. This structure is simple and easy to implement. Of course, in other embodiments, the temple 500 may also have a protruding rib on its end face facing the frame 600, which serves as the second sliding protrusion 502. In other embodiments, the second sliding protrusion 502 may also be provided on the end face of the mounting base 110. For example, the end face of the mounting base 110 protrudes beyond the end face of the temple 500, and the mounting base 110 has a third protruding rib formed between its end face and the side surface away from the rotation axis of the first support 100. The third protruding rib is configured as the second sliding protrusion 502.

[0092] Referring to Figure 11, optionally, the second bracket 200 includes a mounting portion 210 and a rotating portion 220 connected together. The mounting portion 210 is disposed on the frame 600, and the second rotating portion 220 is rotatably connected to the first bracket 100. The second guide surface 202 is disposed on the end face of the mounting portion 210 near the first bracket 100. Thus, by using the end face of the mounting portion 210 as the second guide surface 202, compared to disposing of the second guide surface 202 on the frame 600, the problem of wear or scratches on the surface of the frame 600 due to long-term sliding contact with the second sliding protrusion 502 can be avoided, thereby improving the service life of the frame 600. Optionally, the second guide surface 202 is flush with the outer surface of the frame 600. Of course, in other embodiments, the surface of the frame 600 may have the second guide surface 202, or the second guide surface 202 may protrude from the outer surface of the frame 600.

[0093] Optionally, the mounting part 210 is fixed to the frame 600 by adhesive bonding. Of course, in other embodiments, it can also be fixed to the frame 600 by welding, screws, or rivets.

[0094] Referring to Figure 7, optionally, the mounting base 110 further includes a second plate portion 116 connecting the two first plate portions 115. The second plate portion 116, the first plate portions 115, and the base plate portion 114 together enclose a receiving cavity 102, within which the sliding portion 122 and the elastic member 300 are disposed. Thus, by concealing the sliding portion 122 and the elastic member 300 within the receiving cavity 102, the dustproof effect of the temple connection structure can be improved, and the problem of these two moving parts malfunctioning due to dust or foreign objects can be avoided. Of course, in other embodiments, the receiving cavity 102 may not be provided.

[0095] Without loss of generality, a functional component is usually installed between the temple 500 and the frame 600 of the head-mounted display device. This functional component includes, but is not limited to, a wiring harness, a flexible printed circuit board, or a flexible heat-conducting component. For example, when the functional component is a wiring harness, it can connect two electronic components located on the temple 500 and the frame 600. Specifically, the battery on the temple 500 can supply power to the control board located on the frame 600 through the wiring harness.

[0096] It is understandable that the first bracket 100 can rotate approximately 90° relative to the second bracket 200. During this process, from the outer or inner viewpoint of the temple 500, a gap will inevitably form between the first bracket 100 and the second bracket 200. When a gap appears between the temple 500 and the frame 600, the portion of the functional components that passes between the temple 500 and the frame 600 will be exposed, thus affecting the neatness and aesthetics of the device.

[0097] Therefore, to improve the neatness and aesthetics of the device, in one embodiment, the temple connection structure further includes a shielding structure that can shield the mating gap formed by the relative rotation between the first support 100 and the second support 200. Specifically, by shielding the mating gap with the shielding structure to provide protection and dust prevention, the risk of dust or foreign objects entering the hinge of the first support 100 and the second support 200 can be reduced. Simultaneously, it prevents functional components passing between the temple 500 and the frame 600, or the internal structure of the temple connection structure (such as the sliding part 122 and the elastic element 300), from being exposed, thus improving the neatness and aesthetics of the device from the outside or inside viewpoints of the temple 500. Of course, in other embodiments, the shielding structure may not be provided.

[0098] Please refer to Figures 3 and 8. Optionally, the first bracket 100 includes a mounting base 110 and a connecting bracket 120. The connecting bracket 120 includes a first rotating part 121 and a baffle part 124. The second bracket 200 is provided with a second rotating part 220. The first rotating part 121 is rotatably connected to the second rotating part 220. The mounting base 110 is fixed to the temple 500 or the frame 600 and is movably connected to the connecting bracket 120 so that it can approach or move away from the first rotating part 121. The baffle part 124 is connected to the first rotating part 121 and extends to the side of the mounting base 110. The mating gap includes the interval between the mounting base 110 and the first rotating part 121. The blocking structure includes the baffle part 124 for blocking the interval between the mounting base 110 and the first rotating part 121.

[0099] The baffle portion 124 can extend to either the outer side or the inner side of the mounting base 110. Referring to Figure 8, in this embodiment, optionally, the baffle portion 124 extends to the inner side of the mounting base 110. When the mounting base 110 is located closest to the first rotating part 121, the exposed portion of the baffle portion 124 will be narrower, thereby improving the aesthetics of the device.

[0100] Specifically, when the mounting base 110 moves away from the first rotating part 121, the gap between the mounting base 110 and the first rotating part 121 widens, and the width of the baffle part 124 exposed at the gap also increases; when the mounting base 110 moves closer to the first rotating part 121, the gap between the mounting base 110 and the first rotating part 121 narrows, and the width of the baffle part 124 exposed at the gap also decreases.

[0101] Thus, when the mounting base 110 moves relative to the first rotating part 121 as the temple 500 rotates, the baffle part 124 can effectively block the fitting gap between the mounting base 110 and the first rotating part 121, thereby achieving a good shielding and dustproof effect.

[0102] Specifically, there are various possibilities for the variation in the gap width between the mounting base 110 and the first rotating part 121. For example, referring to Figures 12 and 13, in one embodiment, the temple connection structure further includes an elastic element 300 connecting the first support 100 and the second support 200. The first support 100 or temple 500 is provided with a second sliding protrusion 502, and the second support 200 is provided with a second guide surface 202. During the unfolding process of the temple 500 from the open position to the outward extreme position, the second sliding protrusion 502 slides against the second guide surface 202, and the distance between the second sliding protrusion 502 and the rotation axis of the first support 100 decreases, thereby increasing the elastic deformation of the elastic element 300 and increasing the gap width between the mounting base 110 and the first rotating part 121. In this way, when the temple 500 is folded outward, the elastic force of the elastic element 300 can be converted into the clamping force of the temple 500, so that the temple 500 is not easy to slip off the head when the user wears the device. Based on this, due to the presence of the baffle portion 124, when the temple 500 is turned outward, the internal structure or functional components of the temple connection structure will not be exposed due to the increased gap width between the mounting base 110 and the first rotating portion 121.

[0103] Optionally, the first bracket 100 further includes a sliding portion 122 that connects to the first rotating portion 121 and is slidably connected to the mounting base 110. The mounting base 110 has a receiving cavity 102 with its opening facing the first rotating portion 121. The elastic member 300 is disposed within the receiving cavity 102 and connects the sliding portion 122 and the mounting base 110. The baffle portion 124 extends into the opening of the receiving cavity 102. In this way, the elastic member 300 and functional components are concealed by the cavity sidewall of the receiving cavity 102 and the baffle portion 124, resulting in a simple structure that is easy to implement. Furthermore, the fact that the sliding portion 122 and the elastic member 300 are disposed within the receiving cavity 102 helps to avoid the problem of these two moving parts being affected by dust or foreign objects and failing to operate normally. Of course, in other embodiments, the receiving cavity 102 may not be provided.

[0104] Referring to Figures 3 and 8, optionally, the inner surface of the temple 500 is provided with a mounting groove 501, and the mounting base 110 is disposed in the mounting groove 501. The rotation axis of the first rotating part 121 and at least part of the cavity opening of the receiving cavity 102 are located outside the groove opening of the mounting groove 501. In this way, the outer surface of the temple 500 is exposed as a complete plane or curved surface, which can improve the aesthetics of the device. Secondly, by installing the mounting base 110 in the mounting groove 501, the connection strength and installation reliability between the first bracket 100 and the temple 500 can be improved. Furthermore, by accommodating part of the structure of the first bracket 100 in the mounting groove 501, the structure of the first bracket 100 exposed outside the temple 500 can be made more compact, which can improve the aesthetics.

[0105] Furthermore, the rotation axis of the first rotating part 121 is located outside the groove of the mounting groove 501, that is, the portion of the first bracket 100 protruding from the temple 500 is rotatably connected to the second bracket 200. Thus, the first bracket 100 and the second bracket 200 serve as a hinge structure between the temple 500 and the frame 600. By arranging the structure around the rotation axis on the outside of the temple 500, compared to the prior art, the temple 500 no longer needs to completely cover this part of the structure, thereby removing the limitation on the thickness of the temple 500 and allowing the temple 500 to be made thinner. In other words, the temple connection structure of this embodiment can be adapted to ultra-thin temples 500.

[0106] Please refer to Figures 3, 8 and 12. Optionally, the mounting base 110 includes a base plate portion 114, two first plate portions 115 and a second plate portion 116. The two first plate portions 115 are disposed on opposite sides of the base plate portion 114. The second plate portion 116 is connected to the first plate portion 115 and is disposed opposite to the base plate portion 114. The first plate portion 115, the second plate portion 116 and the base plate portion 114 together define a receiving cavity 102. The baffle portion 124 includes a middle plate section 125 and two side plate sections 126 disposed on both sides of the middle plate section 125. The side plate sections 126 extend to the inner side of the first plate portion 115 and the middle plate section 125 extends to the inner side of the second plate portion 116. That is, the cross-sectional shape of the baffle portion 124 is roughly U-shaped, the side plate section 126 is responsible for blocking the gap between the first plate portion 115 and the first rotating portion 121, and the middle plate section 125 is responsible for blocking the gap between the second plate portion 116 and the first rotating portion 121, so as to more comprehensively play the role of blocking and dust prevention.

[0107] Referring to Figures 3, 8, and 12, optionally, the first support 100 is provided with two first rotating parts 121 spaced apart, and the second support 200 is provided with two corresponding second rotating parts 220. One first rotating part 121 is rotatably connected to one second rotating part 220. The shielding structure also includes a shielding member 400, which extends around the rotation axis of the first support 100 and shields the axial gap between the two second rotating parts 220. In this way, by using the shielding member 400 to cover the hinge area of ​​the first rotating part 121 and the second rotating part 220, the risk of dust or foreign objects entering the hinge area and causing abnormal rotation can be reduced.

[0108] Optionally, the second bracket 200 includes a mounting portion 210 and a connecting portion 230. The mounting portion 210 is disposed on the frame 600, and the connecting portion 230 connects between the two second rotating portions 220 and is connected to the mounting portion 210. The second rotating portions 220 are offset to the outside of the connecting portion 230, and the outer surface of the second rotating portions 220 protrudes beyond the outer surface of the connecting portion 230. The blocking member 400 extends from the inner edge to the outer edge of the connecting portion 230. Thus, the second rotating portions 220 being offset to the outside of the connecting portion 230 allows for a more compact temple connection structure. Of course, in other embodiments, the second rotating portions 220 may also be offset to the inside of the connecting portion 230, or the second rotating portions 220 may be centrally disposed on the connecting portion 230.

[0109] Optionally, the shielding member 400 has a circular cross-sectional shape, with the central angle corresponding to the extension of the shielding member 400 around the rotation axis being greater than 200° and less than 350°, for example, the central angle being 270°. In this way, the shielding member 400 can achieve a large-area shielding effect of more than 180° on both the inner and outer sides of the rotation axis, thereby improving the aesthetics of the device. Of course, in other embodiments, the cross-sectional shape of the shielding member 400 can also be polygonal or elliptical, etc.

[0110] Specifically, please refer to Figure 8. When the temple 500 is in the open position, the shielding member 400 is partially exposed in the gap between the baffle portion 124 and the connecting portion 230. The shielding member 400 is exposed both in the inner gap between the baffle portion 124 and the connecting portion 230 and in the outer gap between the baffle portion 124 and the connecting portion 230. However, the outer gap is not exposed because it is further shielded by the temple 500.

[0111] Please refer to Figures 10, 14 and 15. When the temple 500 is in the folded position, since there is no inner gap between the baffle portion 124 and the connecting portion 230 and the outer gap is at its maximum, the shielding member 400 is only exposed in the outer gap between the baffle portion 124 and the connecting portion 230 and can basically cover the outer gap.

[0112] Referring to Figure 11, when the temple 500 is in its outward-folding limit position, the obstruction member 400 is exposed both in the inner gap between the baffle portion 124 and the connecting portion 230 and in the outer gap between the baffle portion 124 and the connecting portion 230. However, the outer gap is further obstructed by the temple 500 and is not exposed to the outside. As the inner gap widens, the width of the exposed portion of the obstruction member 400 also increases accordingly.

[0113] Referring to Figures 3, 7, and 8, optionally, the second rotating part 220 includes two opposing positioning ribs 222, and the first rotating part 121 is inserted between the two positioning ribs 222 and rotatably connected to the positioning ribs 222 via a pin 240. In this way, the two positioning ribs 222 together limit and abut against the opposite sides of the first rotating part 121, preventing axial wobbling of the first rotating part 121. Of course, in other embodiments, only one rib may be provided.

[0114] It is understood that there are various ways to install the shielding member 400. For example, referring to Figures 3 and 9, in one embodiment, the shielding member 400 is provided with an installation opening 401, the edge of which is elastically engaged with the positioning rib 222. Specifically, the installation opening 401 extends axially and penetrates the opposite end faces of the shielding member 400. That is, the cross-section of the shielding member 400 and the outer contour of one of the positioning ribs 222 are approximately C-shaped, allowing the shielding member 400 to be directly and elastically fastened to the positioning rib 222. The other positioning rib 222 is provided with a first protruding ridge 221. Thus, by reusing the positioning rib 222 as the fastening structure of the shielding member 400, the structure is not only simple but also easy to assemble and disassemble. Of course, in other embodiments, the shielding member 400 can also be installed using fasteners such as screws or rivets, or directly welded or bonded to the second rotating part 220.

[0115] Referring to Figure 9, optionally, the second bracket 200 is provided with a clearance through hole 203 penetrating the mounting portion 210 and the connecting portion 230, the first bracket 100 is provided with a receiving cavity 102, and the shielding member 400 is also provided with a clearance opening 402 opposite to the mounting opening 401 (the clearance opening 402 is shown in Figure 9, but not in Figure 3). The clearance opening 402 communicates with the receiving cavity 102, and the mounting opening 401 penetrates the opposite end faces of the shielding member 400 axially and communicates with the clearance through hole 203. The clearance opening 402, the mounting opening 401, the clearance through hole 203, and the receiving cavity 102 can all accommodate functional components. The functional components include at least one of a wire harness, a flexible printed circuit board, and a flexible heat-conducting component. Thus, the temple connection structure can also accommodate and install functional components, resulting in a simple and easy-to-implement structure. Of course, in embodiments where the device does not have functional components, the clearance opening 402 and the clearance through hole 203 may not be provided.
