[0060] Description of Figure Numbers:

[0061] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0062] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0063] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0064] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0065] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0066] This application proposes a temple connection structure for connecting the temples and frames of eyewear products. For example, the temples of a head-mounted display device can be mounted on the frame via the temple connection structure. The temples can generate a clamping force when worn, clamping the temples to the user's head, thereby improving the wearing stability of the head-mounted display device. Among these head-mounted display devices, examples include, but are not limited to, AR glasses, VR glasses, and MR glasses. For example, AR glasses have a frame that is typically equipped with a display module to provide image information to the user's eyes.

[0067] It should be noted that in the process of gradually unfolding the temples from the folded state, they pass through the folded position, the open position and the eversion limit position in sequence. When in the folded position, the free end of the temple is adjacent to or abuts against the frame. When in the open position or the eversion limit position, the free end of the temple is away from the frame. The temples have multiple wearing states between the open position and the eversion limit position to allow users with different head sizes to wear them normally.

[0068] Referring to FIG. 1 to FIG. 4 , in one embodiment of the present application, the connection structure of the temple 52 includes:

[0069] Base 10;

[0070] Two mounting brackets 20 are rotatably connected to the base 10 around a reference axis. The two mounting brackets 20 include a first bracket 21 and a second bracket 22. The first bracket 21 is corresponding to the mounting of the temple 52, and the second bracket 22 is corresponding to the mounting of the frame 51. At least one mounting bracket 20 is provided with a first push portion 23.

[0071] The slider 30 is slidably disposed on the base 10 along the extending direction of the reference axis. The slider 30 is provided with a second push portion 31 corresponding to the first push portion 23. The first push portion 23 slides against the second push portion 31.

[0072] The elastic member 40 connects the slider 30 and the base 10 and is capable of elastic deformation along the extension direction of the reference axis;

[0073] When the temple 52 is turned outward from the open position (i.e., rotated from the open position toward the extreme outward position), it will drive the first bracket 21 to rotate around the reference axis, and the first push portion 23 will push the second push portion 31, so that the slider 30 moves in a direction away from the first push portion 23 and puts the elastic member 40 in an elastic deformation state.

[0074] It can be understood that the folded position of the first bracket 21 corresponds to the folded position of the temple 52, the open position of the first bracket 21 corresponds to the open position of the temple 52, the eversion limit position of the first bracket 21 corresponds to the eversion limit position of the temple 52, and the process of eversion of the first bracket 21 from the open position corresponds to the process of eversion of the temple 52 from the open position.

[0075] That is, when the first bracket 21 is turned outward from the open position, the elastic member 40 has elastic potential energy and can cause the slider 30 to move toward the first push portion 23, and the second push portion 31 pushes the first push portion 23 to make the first bracket 21 tend to return to the open position.

[0076] In the technical solution of the present application, it is defined that when the temple 52 is in the open position, the slider 30 is in the starting position on the base 10. In the process of the temple 52 being turned outward from the open position, since the elastic member 40 has a certain deformation amount, that is, it has a certain elastic potential energy, the elastic member 40 can generate a force to push the slider 30 toward its starting position, and the slider 30 transmits the elastic force it receives to the first push portion 23 through the second push portion 31, and converts the part of the force applied by the slider 30 to the first bracket 21 into a clamping force tangential to the rotation direction of the first bracket 21. The clamping torque constituted by the clamping force can resist the continued outward turning of the first bracket 21, that is, the first bracket 21 has a tendency to return to its open position, thereby making the temple 52 have a tendency to rotate toward its open position. It can be understood that the temples 52 have a tendency to rotate toward their open position, which can increase the clamping force of the temples 52 to clamp the user's head when worn. This clamping force is conducive to the stable and reliable wearing of the eyewear product. In this way, the temples 52 can fit well on the head and reduce the risk of the temples 52 and the device slipping forward.

[0077] Secondly, the clamping force of the temple 52 is perpendicular to the reference axis, and the elastic member 40 elastically deforms along the extension direction of the reference axis. Therefore, in the process of the elastic force of the elastic member 40 being indirectly converted into the clamping force of the temple 52, the clamping force of the temple 52 will not increase linearly with the increase of the elastic force, which is conducive to stabilizing the clamping force of the temple 52 within a certain numerical range, thereby improving the wearing comfort of the temple 52.

[0078] It should be noted that when the temple 52 is in the open position, the elastic member 40 can be in a compressed or stretched state, that is, the elastic member 40 has a pre-deformation and the initial elastic potential energy of the elastic member 40 is not zero; or the elastic member 40 can be in a natural state, that is, the elastic member 40 has no pre-deformation and the initial elastic potential energy of the elastic member 40 is zero. In the former case, when the temple 52 is everted from the open position, the deformation of the elastic member 40 can increase or decrease, that is, the elastic potential energy can increase or decrease, as long as the elastic potential energy is maintained; in the latter case, when the temple 52 is everted from the open position, the deformation of the elastic member 40 increases from zero. That is, if the deformation of the elastic member 40 when the slider 30 is in the starting position is the pre-deformation, then the value of the pre-deformation is greater than or equal to 0.

[0079] In addition, the meaning of the increase or decrease of the elastic potential energy of the elastic member 40 includes but is not limited to the elastic potential energy suddenly changing 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.

[0080] It is worth mentioning that when the elastic member 40 has a non-zero initial elastic potential energy, the clamping torque applied to the first bracket 21 during the outward rotation from the open position is less likely to experience a sudden change in amplitude, allowing the user to perceive a smoother change in the clamping force of the temple 52, thereby providing the temple 52 with a better operating feel. Of course, in other embodiments, the elastic member 40 may have no initial elastic potential energy, that is, the initial elastic potential energy may be zero.

[0081] It is understood that if one wishes to further enhance the feel of the temple 52 when everting, the clamping torque of the first bracket 21 may be limited to a certain value range, and regardless of how the eversion angle of the temple 52 changes, the clamping torque can be substantially maintained at a certain value, such as, but not limited to, 150 N*mm, 180 N*mm, 200 N*mm, 220 N*mm, or 250 N*mm. In this way, since the clamping torque is substantially constant, the problem of excessive clamping force as the eversion angle of the temple 52 increases can be avoided, thereby improving the comfort of use of the eyewear product.

[0082] Preferably, within the eversion angle range of 2° to 15° when the temple 52 is everted from the open position, the amplitude fluctuation of the clamping torque is kept within 10%. For example, taking the clamping torque M = 200N*mm as an example, the numerical change can be controlled between 180N*mm and 220N*mm, so the operating feel and wearing comfort of the temple 52 when worn are relatively ideal.

[0083] Please refer to Figures 10 to 16. In order to make the clamping torque M approximately constant, in one embodiment, optionally, one of the first push portion 23 and the second push portion 31 is provided with an outward convex arc surface 31a, and the other is provided with a first sliding protrusion 23a that can slide on the outward convex arc surface 31a; during the process of the first bracket 21 rotating from the open position toward the outward extreme position, the angle between the tangent plane of the outward convex arc surface 31a at the contact point with the first sliding protrusion 23a and the reference axis gradually increases, and the elastic deformation of the elastic member 40 gradually increases.

[0084] Specifically, the embodiments shown in Figures 10 to 15 are used as an example for explanation. At this time, the convex arc surface is provided on the second push portion, and the first sliding protrusion is provided on the first push portion. In the direction along the reference axis and away from the first push portion, the angle between the tangent plane of the convex arc surface and the reference axis gradually decreases. Please refer to Figures 5 and 6. When the temple is in the open position, the contact point of the first sliding protrusion on the convex arc surface is defined as the initial contact Q0, the XOY plane is defined as passing through the initial contact Q0 and perpendicular to the reference axis, the intersection of the reference axis and the XOY plane is defined as the coordinate pole O (coordinate origin O), the polar axis is defined as the ray starting from the coordinate pole O and passing through the initial contact Q0 (which is also the positive direction of the X-axis), the reference axis is defined as the Z-axis and the direction in which the slider moves close to its starting position is the positive direction of the Z-axis. A cylindrical coordinate system is constructed according to the above definition. Then, the cylindrical coordinates of the contact point Q of the first sliding protrusion on the convex arc surface are Where r is the vertical distance between the contact point Q and the Z axis, is the angle between the projection line of line segment OQ on the XOY plane and the polar axis OQ0, and z is the distance between the contact point Q and the XOY plane. It can be understood that when the temple continues to turn outward from the open position, That is, it represents the angle of rotation of the first bracket around the reference axis (which is also the eversion angle of the temple), r represents the rotation radius of the contact point Q from the reference axis, and z represents the further deformation amount Δx of the elastic member.

[0085] Further, referring to the force analysis diagram in FIG11 , the force F exerted by the slider on the first bracket through the contact point Q is N Perpendicular to the convex arc surface, define a reference plane perpendicular to the X axis and passing through the force F N , the force F N Decomposed into two perpendicular components F on the reference plane k and F T , where F k This means the elastic force from the elastic member, F T This means the clamping force tangential to the rotation direction of the first bracket, or F T Perpendicular to the rotation radius of the first bracket, F N With F T The angle θ represents the angle between the tangent plane of the outer convex arc surface at the contact point with the first sliding protrusion and the reference axis, and θ is greater than or equal to 0 and less than 90°.

[0086] Then we have formula ①: F T =F k *cotθ; and formula ②: M=F T *r=F k *cotθ*r.

[0087] It can be understood that in the process of the temple turning outward from the open position, although the slider gradually moves away from the first push portion and the deformation of the elastic member gradually increases, the elastic force F k gradually increases, but because the angle θ gradually decreases and cotθ gradually decreases, F T Not with valgus angle increases linearly, that is, F T Since the rotation radius r remains substantially constant, the clamping moment M of the first bracket can be kept substantially constant, thereby making the clamping force of the temples acting on the head substantially constant.

[0088] Without loss of generality, F k =K*(Δx0+Δx), where K represents the elastic coefficient of the elastic member, Δx0 represents the pre-deformation of the elastic member when the first bracket is in the open position, and the initial elastic potential energy F k0 =K*Δx0; Δx represents the deformation of the elastic member when the first bracket is further deformed when it is turned outward from the open position, and Δx is proportional to the eversion angle Satisfy the formula

[0089] Furthermore, F k =K*(Δx0+Δx), F k0 =K*Δx0 and Substituting into formula ②, we get formula ③:

[0090] According to the deduction of formula ③, we can get formula ④:

[0091] Since the coordinate pole O of the cylindrical coordinate system corresponds to the open position of the first bracket, That is, it corresponds to the state of the elastic member Δx=0, and therefore, the cylindrical coordinate value z of the contact point Q is z=Δx.

[0092] Furthermore, the rectangular coordinates of the contact point Q can be expressed as That is, the rectangular coordinates x, y, and z of the contact point Q can be expressed by equations ⑤, ⑥, and ⑦, respectively, as follows:

[0093] Formula ⑤:

[0094] Formula ⑥:

[0095] Formula 7:

[0096] It can be understood that by designing and manufacturing the convex arc surface according to the rectangular coordinates of the above-mentioned contact point Q, the produced slider can make the clamping torque M as roughly constant as possible at the ideal value when it is matched with the corresponding mounting bracket, such as the 200N*mm mentioned in the previous example.

[0097] Of course, due to The value range is 2° to 15°, that is, Very small, then and The values ​​are very close, so we can use Equivalent replacement Then the formula ⑧ is obtained, and those skilled in the art can select it according to design requirements, and this application does not make any specific limitation.

[0098] Specifically, formula ⑧:

[0099] It should be noted that the contact modes between the first sliding protrusion and the outer convex curved surface include, but are not limited to, point contact, line contact, and surface contact. For the latter two, the contact point Q refers to the midpoint between the contact line and the contact surface. Preferably, the outer convex curved surface is designed to have line contact according to the rectangular coordinate formula for the contact point Q, thereby improving the smoothness and stability of force transmission and also facilitating the service life of the temple connection structure.

[0100] Of course, other formulas can also be used to define the rectangular coordinates (x, y, z) of the contact point Q, and further define the convex arc surface, as long as the rectangular coordinates (x, y, z) of the contact point Q satisfy the following relationship:

[0101] The value of the coordinate x changes with the rotation angle of the first bracket As the value of x increases, it gradually decreases, and the rate of change of the coordinate value x gradually increases;

[0102] The value of the coordinate y changes with the rotation angle of the first bracket , and the rate of change of the coordinate value y gradually decreases;

[0103] The value of the coordinate z changes with the rotation angle of the first bracket , and the rate of change of the coordinate value z gradually decreases.

[0104] In some embodiments, please refer to Figure 16, the convex arc surface may be provided on the first push portion, and the first sliding protrusion may be provided on the second push portion. In the direction along the reference axis and away from the first push portion, the angle between the tangent plane of the convex arc surface and the reference axis gradually increases.

[0105] Of course, it is not necessary to make the clamping torque M substantially constant. In other embodiments, the clamping torque M may also vary with the valgus angle. It can be gradually increased with the increase of the temple, as long as the temple has a clamping force during the eversion process.

[0106] Referring to Figures 2, 5, 7, 8, 10 to 15, and 17 to 24, in some embodiments, the mounting bracket 20 optionally further includes a third push portion 24, and the slider 30 correspondingly includes a fourth push portion 32. The temple 52 has a critical position during its rotation from the open position to the folded position. At this critical position, the slider 30 is farthest from the first push portion 23. At least from the critical position to the initial interval of the folded position, the slider 30 is moved toward the first push portion 23 by the elastic member 40. It should be noted that the distance between the slider 30 and the first push portion 23 refers to the distance between the center point of the slider 30 and the center point of the first push portion 23 along the reference axis.

[0107] Specifically, during the process of folding and storing the temples 52 from the open position, once the temples 52 flip over the critical position, the slider 30 is rapidly moved toward its starting position by the elastic force of the elastic member 40, prompting the temples 52 to quickly rotate toward the folded position, thereby achieving a slingshot-like folding function. This facilitates the user's folding and storing of the temples 52, and the presence of the critical position also prevents the temples 52 from automatically unfolding to the open position. Of course, in other embodiments, the critical position may not be provided.

[0108] Further optionally, the fourth push portion 32 is configured as a fourth sliding protrusion, and the third push portion 24 is configured as a third sliding protrusion. When the temple 52 is in the critical position, the tip of the fourth sliding protrusion abuts the tip of the third sliding protrusion. That is, at least from the critical position to the initial interval of the open position, the slider 30 is moved toward the first push portion 23 by the elastic member 40. It will be appreciated that the sidewalls of the third and fourth sliding protrusions both have a significant slope, enabling the slider 30 to move rapidly after crossing the critical position, thereby enabling the temple 52 to simultaneously perform both ejection folding and ejection unfolding functions.

[0109] Specifically, as the temples 52 gradually unfold from their folded positions, once the temples 52 pass the critical position, the sliders 30, under the elastic force of the elastic member 40, rapidly move toward their starting position, causing the temples 52 to rapidly rotate toward the open position, thereby achieving a slingshot-like catapulting unfolding function. This facilitates the user's unfolding of the temples 52 and, due to the critical position, prevents the temples 52 from automatically folding back to their folded positions. Of course, in other embodiments, only the catapulting folding function may be configured without the catapulting unfolding function, or only the catapulting unfolding function may be configured without the catapulting folding function.

[0110] Referring to Figures 10 to 15, 22, and 24, further optionally, the second push portion 31 and the fourth push portion 32 are spaced apart in the circumferential direction of the reference axis and define a positioning groove 33. When the temple 52 is in the open position, the first push portion 23 and the third push portion 24 at least partially engage with the positioning groove 33. That is, when the temple 52 is in the open position, the first push portion 23 abuts the second push portion 31 while the third push portion 24 also abuts the fourth push portion 32. At this point, the elastic member 40 has initial elastic potential energy, and the second push portion 31 and the fourth push portion 32 work together to maintain a stable mechanical equilibrium of the mounting bracket 20 on the base 10, thereby allowing the temple 52 to stabilize in the open position. Of course, in other embodiments, the first push portion 23 and the third push portion 24 may not engage with the positioning groove 33.

[0111] Referring to Figures 5, 7, and 15, in some embodiments, optionally, two fourth protrusions are provided, one on opposite sides of the reference axis, and two third protrusions are provided, one on opposite sides of the reference axis, with the third and fourth protrusions being arranged in a one-to-one correspondence. This improves the stability of force transmission between the slider 30 and the mounting bracket 20, making the forces on the mounting bracket 20 and the slider 30 more balanced and stable, thereby improving the structural stability of the connection structure of the temple 52. Of course, in other embodiments, only one third protrusion and one fourth protrusion may be provided.

[0112] Referring to Figures 2, 8, 9, 18 to 20, and 23, in some embodiments, the base 10 optionally includes a mounting seat 11 and a guide post 12. The mounting seat 11 includes a main plate portion 111 and two opposing side plates 112, each disposed at either end of the main plate portion 111. The guide post 12 connects the two side plates 112, with the central axis of the guide post 12 serving as a reference axis. The slider 30 is slidably mounted on the guide post 12. This structure is not only simple and easy to implement, but also facilitates the installation of the slider 30 and the elastic member 40, and improves the smoothness and stability of the slider 30's movement. Of course, in some embodiments, the mounting seat 11 may be provided with a guide rail, and the slider 30 may be provided with a slide groove corresponding to the guide rail, which slides on the guide rail. In other embodiments, the base 10 may be provided with only the guide post 12, without the mounting seat 11, and the guide post 12 may be directly mounted on the temple 52 or the frame 51.

[0113] It is understood that the reference axis can be one or two. For example, referring to Figures 2, 8, and 9, in some embodiments, two guide posts 12 are provided, and the central axes of the two guide posts 12 serve as the reference axis. That is, the two reference axes are parallel and spaced apart. Two mounting brackets 20 are mounted in a one-to-one correspondence with the two guide posts 12. The mounting brackets 20 are also provided with meshing teeth 25, and the two mounting brackets 20 rotate in conjunction with each other through the meshing teeth 25. That is, the first bracket 21 rotates about the central axis of the guide post 12 closest to it, and the second bracket 22 rotates about the central axis of the guide post 12 closest to it, and the two mounting brackets 20 rotate about their respective reference axes. In this way, the two mounting brackets 20 are linked to each other through the two meshing teeth 25. When the temple 52 rotates a certain angle, the frame 51 can also rotate accordingly, thereby improving the rotational sensitivity and convenience of the temple 52 and frame 51. It should be noted that "parallel" refers to a state of being parallel or nearly parallel.

[0114] Referring to Figures 1 to 5 and 7 to 10 , in an embodiment in which two guide posts 12 are provided, two elastic members 40 are optionally provided, each corresponding to one of the two guide posts 12. The first bracket 21 and the second bracket 22 each have a first push portion 23, and the slider 30 has two opposing second push portions 31. When the first push portion 23 of the first bracket 21 abuts one second push portion 31, the first push portion 23 of the second bracket 22 simultaneously abuts the other second push portion 31. Specifically, under the transmission of the meshing teeth 25, during the unfolding or folding process of the temple 52, both mounting brackets 20 exert a force on the slider 30 to force the slider 30 to move, and both mounting brackets 20 can also receive the reaction force of the slider 30, thereby generating a clamping force on the temple 52. Thus, by providing two sets of guide posts 12 and elastic members 40, both the temple 52 and the frame 51 can be subjected to the force of the elastic members 40, thereby increasing the force transmission path and improving the stability of the force transmission. Further optionally, in an embodiment in which the mounting bracket 20 is provided with a third pushing portion 24 , both the first bracket 21 and the second bracket 22 are also provided with a third pushing portion 24 .

[0115] It will be understood that in the embodiment where two guide posts 12 are provided, only one elastic member 40 may be provided, and the first push portion 23 may be provided on either the first bracket 21 or the second bracket 22, with the elastic member 40 being provided on the guide post 12 corresponding to the first push portion 23. When the first push portion 23 is provided on the first bracket 21, the elastic force of the elastic member 40 is directly transmitted to the first bracket 21 via the slider 30; whereas, when the first push portion 23 is provided on the first bracket 21, the elastic force of the elastic member 40 is first transmitted to the second bracket 22 via the slider 30, and then transmitted to the first bracket 21 via the meshing teeth 25 between the second bracket 22 and the first bracket 21.

[0116] In the embodiment where two guide posts 12 are provided, further optionally, a single slider 30 is provided, the slider 30 being sleeved on the two guide posts 12, and the slider 30 being provided with two opposing second push portions 31. That is, each mounting bracket 20 is provided with a first push portion 23, which is capable of cooperating with a second push portion 31 adjacent thereto on the same slider 30. This simplifies the structure while enabling the rotation of the two mounting brackets 20 to be linked, further enhancing the stability and smoothness of force transmission. Of course, in other embodiments, two sliders 30 may also be provided, with the two sliders 30 being installed in a one-to-one correspondence with the two guide posts 12. That is, each guide post 12 is equipped with a slider 30, and the two sliders 30 move independently of each other.

[0117] Referring to Figures 17 to 24 , of course, in other embodiments, both the guide post 12 and the elastic member 40 are provided as a single unit, with only one corresponding reference axis. The two mounting brackets 20 rotate about the central axis of the same guide post 12, and the first pusher 23 is provided on the first bracket 21. In this embodiment, only the first bracket 21 is provided with the first pusher 23 and the third pusher 24; the second bracket 22 is not provided with the first pusher 23 and the third pusher 24. This allows the reaction force generated by the slider 30 via the first pusher 23 or the third pusher 24 to be directly transmitted to the first bracket 21, thereby effectively acting on the temple 52 on the first bracket 21. Thus, by providing only a single guide post 12 and elastic member 40, the connection structure of the temple 52 can be simplified and its manufacturing cost can be reduced.

[0118] Referring to Figures 17 to 24 , in an embodiment in which a single guide post 12 is provided, the first bracket 21 optionally includes a first mounting portion 201, a first cylindrical portion 202, and a second cylindrical portion 203 disposed on the same side of the first mounting portion 201. The guide post 12 passes through the first cylindrical portion 202 and the second cylindrical portion 203. A clearance space 204 is formed between the first cylindrical portion 202 and the second cylindrical portion 203 in the extending direction of the reference axis. The slider 30 is disposed in the clearance space 204, and the first push portion 23 is disposed on the end surface of the first cylindrical portion 202 adjacent to the second cylindrical portion 203. This provides a simple structure and is easy to implement.

[0119] In an embodiment in which one guide post 12 is provided, the second bracket 22 optionally includes a second mounting portion 221, a third cylindrical portion 222, and a fourth cylindrical portion 223 disposed on the same side of the second mounting portion 221. The third cylindrical portion 222 is disposed on a side of the first cylindrical portion 202 away from the second cylindrical portion 203, and the fourth cylindrical portion 223 is disposed on a side of the second cylindrical portion 203 away from the first cylindrical portion 202. The third cylindrical portion 222 and the fourth cylindrical portion 223 are passed through the guide post 12. In this way, the third cylindrical portion 222 and the fourth cylindrical portion 223 jointly limit the first bracket 21 in the direction of the reference axis, enabling the first bracket 21 to rotate smoothly and stably around the guide post 12 without affecting the sliding movement of the slider 30 within the avoidance space 204.

[0120] In an embodiment in which the guide column 12 is provided as one, further optionally, the second mounting portion 221, the third barrel portion 222, the fourth barrel portion 223 and the mounting seat 11 are provided as an integral part. That is, the two side plates 112 of the mounting seat 11 serve as the third barrel portion 222 and the fourth barrel portion 223, respectively, and the second mounting portion 221 is further extended on one side. In this way, the structure can be further simplified and the cost can be reduced, and the assembly process can be reduced and production efficiency can be improved. Of course, in other embodiments, the second bracket 22 and the mounting seat 11 can also be provided separately, the third barrel portion 222 is provided between the first barrel portion 202 and the one side plate portion 112 of the mounting seat 11, and the fourth barrel portion 223 is provided between the second barrel portion 203 and the other side plate portion 112 of the mounting seat 11.

[0121] Referring to Figures 1 to 5 and 7 to 10, in an embodiment in which two guide posts 12 are provided, optionally, the mounting bracket 20 includes a first mounting portion 201, a first cylindrical portion 202, and a second cylindrical portion 203 provided on the same side of the first mounting portion 201. The guide post 12 passes through the first cylindrical portion 202 and the second cylindrical portion 203. A clearance space 204 is formed between the first cylindrical portion 202 and the second cylindrical portion 203 in the extending direction of the reference axis. The slider 30 is provided in the clearance space 204. The first pushing portion 23 is provided on the end surface of the first cylindrical portion 202 adjacent to the second cylindrical portion 203, and the meshing tooth portion 25 is provided on the circumferential side surface of the second cylindrical portion 203. That is, the first bracket 21 and the second bracket 22 are both provided with the first mounting portion 201, the first cylindrical portion 202, and the second cylindrical portion 203. Thus, the structure is simple and easy to implement.

[0122] Please refer to Figures 2 and 18. In some embodiments, optionally, the third push portion 24 is arranged on the end surface of the first barrel portion 202 close to the second barrel portion 203, the third push portion 24 and the first push portion 23 are distributed along the circumference of the first barrel portion 202, and the third push portion 24 is arranged on the side of the first push portion 23 close to the first mounting portion 201.

[0123] Referring to Figures 2 and 18 , in some embodiments, the first barrel portion 202 optionally includes a limiting groove 205 on an end surface away from the second barrel portion 203. The limiting groove 205 extends along the circumference of the first barrel portion 202, and the side plate portion 112 includes a limiting protrusion 113 corresponding to the limiting groove 205. When the first bracket 21 is in the externally extended limit position, the limiting protrusion 113 abuts one end surface of the limiting groove 205, and when the first bracket 21 is in the folded position, the limiting protrusion 113 abuts the other end surface of the limiting groove 205. Thus, the limiting protrusion 113 cooperates with the limiting groove 205 to define two limit positions for the mounting bracket 20 to rotate relative to the base 10, thereby preventing the temples 52 from excessively extending or folding, and protecting the temples 52 and the frame 51. Of course, in other embodiments, the two limit positions for the mounting bracket 20 to rotate relative to the base 10 can also be defined by the mutual abutment between the temples 52 and the frame 51.

[0124] It should be noted that in an embodiment in which the guide column is provided as one and the second mounting portion 221 , the third barrel portion 222 , the fourth barrel portion 223 and the mounting seat 11 are integrally formed, the limit latch 113 is provided on the side plate portion 112 , which means that the limit latch 113 is provided on the third barrel portion 222 .

[0125] Specifically, the first mounting portion 201 of the mounting bracket 20 can be mounted on the temple 52 and the frame 51 by means of fasteners such as screws and rivets, or can be fixed to the temple 52 and the frame 51 by bonding or welding, and this application does not impose any specific restrictions on this.

[0126] Referring to Figures 2, 9, 18, and 23, in some embodiments, the guide post 12 optionally includes a first column segment 121 and a second column segment 122 connected to each other. A limiting step surface 123 is formed between the first column segment 121 and the second column segment 122. The slider 30 slides on the first column segment 121 and is farthest from the first push portion 23 when abutting the limiting step surface 123. In other words, the limiting step surface 123 on the guide post 12 defines an extreme position of the slider 30, resulting in a simple and easy-to-implement structure.

[0127] Referring to Figures 2, 9, 18, and 23, in some embodiments, the elastic member 40 can optionally be configured as a compression spring sleeved on the guide post 12, with one end of the compression spring abutting against the slider 30 and the other end abutting against the side plate portion 112 away from the first push portion 23. In this way, the structure is simple and easy to implement, and it facilitates the installation of the temple 52 connection structure. It is worth mentioning that in the embodiment where the guide post 12 includes a first column section 121 and a second column section 122 connected to each other, the compression spring is sleeved on the second column section 122. Of course, in some embodiments, the elastic member 40 can also be a tension spring, with one end of the tension spring fixed to the slider 30 and the other end fixed to the side plate portion 112 near the first push portion 23. In other embodiments, the elastic member 40 can also be a rubber body or a silicone body.

[0128] Referring to Figures 25 to 30 , this application also provides a head-mounted display device, comprising temples 52, a frame 51, and the aforementioned temple 52 connection structure. The specific structure of the temple 52 connection structure is similar to that of the aforementioned embodiments. Since this head-mounted display device utilizes all of the technical solutions of all of the aforementioned embodiments, it at least has all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and a detailed description thereof will not be repeated here. The temples 52 are mounted on the frame 51 via the temple 52 connection structure.

[0129] Please refer to Figures 25, 26, 28 and 30. In some embodiments, optionally, the head-mounted display device further includes a functional component 54, which includes at least one of a wiring harness, a flexible printed circuit board and a flexible thermal conductor. The base 10 of the temple 52 connection structure includes two opposing main board portions 111, and an installation channel 114 is formed between the two main board portions 111. A first cavity 511 is provided in the frame 51, and a second cavity 521 is provided in the temple 52. An avoidance gap 53 is formed between the cavity openings of the first cavity 511 and the cavity openings of the second cavity 521. The base 10 is at least partially located in the avoidance gap 53, and the first cavity 511, the installation channel 114 and the second cavity 521 are connected and can be passed through by the functional component 54; one main board portion 111 is exposed on the inner side of the avoidance gap 53, and the other main board portion 111 is exposed on the outer side of the avoidance gap 53. In this way, the two main plates 111 of the base 10 respectively shield the inner and outer sides of the avoidance gap 53, thereby protecting the functional components 54 passing through the base 10 and improving the neatness and aesthetics of the head-mounted display device at the connection of the temples 52. Of course, in some embodiments, the base 10 may not be provided with the main plates 111, that is, there is no need to provide a structure for shielding the avoidance gap 53. In other embodiments, the functional components 54 may also be omitted.

[0130] It should be noted that when the head-mounted display device is worn on the user's head, the inner side of the temple 52 refers to the side facing the user's eyes, and the outer side of the temple 52 refers to the side facing away from the user's eyes. The inner side of the avoidance gap 53 is located on the inner side of the temple 52, and the outer side of the avoidance gap 53 is located on the outer side of the temple 52.

[0131] Please refer to Figures 26 and 27. In some embodiments, the head-mounted display device also includes an elastic sealing tube 55, which includes a middle tube section 551 and two side tube sections 552 connected to each other. The two side tube sections 552 are respectively arranged at both ends of the middle tube section 551. The middle tube section 551 passes through the installation channel 114 and surrounds the installation bracket 20, the elastic member 40 and the slider 30. The outer peripheral surface of one side tube section 552 is connected to the inner wall surface of the first cavity 511, and the outer peripheral surface of the other side tube section 552 is connected to the inner wall surface of the second cavity 521. In this way, since the sealing interface, that is, the interface of the edge tube section 552 used to connect the first cavity 511 or the second cavity 521, is stationary relative to the temple 52 or the frame 51 at this position, and is away from the rotation axis area of ​​the mounting bracket 20 and the deformation area of ​​the functional part 54 (such as a flexible circuit board), a static sealing effect is formed, and the functional parts 54 inside the device are completely isolated from the external environment, thereby achieving advanced waterproof functions such as IPX7 or ATM level, thereby improving the reliability of the device.

[0132] Further, optionally, a relief groove 553 is provided in the wall of one side of the middle tube section 551. The relief groove 553 is provided to protrude toward the mounting channel 114. The relief groove 553 is provided corresponding to the end of the main plate portion 111 exposed inside the relief gap 53. Thus, during the rotation of the temple 52 from the open position to the folded position, the main plate portion 111 exposed inside the relief gap 53 gradually extends into the first cavity 511 and the second cavity 521. The provision of the relief groove 553 prevents the main plate portion 111 from pushing against the elastic sealing tube 55, thereby preventing the sealing interface connection of the elastic sealing tube 55 from failing. Furthermore, the force exerted by the elastic sealing tube 55 on the main plate portion 111 can prevent the temple 52 from folding.

[0133] Referring to Figures 28 and 29 , of course, in other embodiments, the elastic sealing tube 55 may be disposed in the clearance gap 53 and on the outer side of the main plate portion 111, with the outer side of the elastic sealing tube 55 abutting against the edges of the first cavity 511 and the second cavity 521. That is, in this embodiment, the relative motion interface between the temple 52 connection structure and the temple 52 and frame 51 at the clearance gap 53 serves as a sealing interface, creating a dynamic sealing effect. The elastic sealing tube 55 does not occupy space in the mounting channel 114 of the base 10, thereby facilitating smoother movement of the temple 52 connection structure.

[0134] Referring to Figure 30 , in yet other embodiments, the elastic sealing tube 55 may comprise two separate elastic tube sections 554, each filling the first cavity 511 and the second cavity 521. The functional component 54 is passed through the elastic tube section 554. In other words, the portion of the temple 52 connection structure and the functional component 54 located in the clearance gap 53 are not sealed. In this embodiment, the sealing interface is located on the peripheral side of the functional component 54, the inner wall of the first cavity 511, and the inner wall of the second cavity 521, away from the rotation axis of the mounting bracket 20. This still provides a static seal, resulting in a simple and easy-to-implement structure.

[0135] Specifically, optionally, the material of the elastic sealing tube 55 may be, for example, but not limited to, rubber or silicone, which is not specifically limited in this application.
