[0037] The present invention also provides a head-mounted display device, including:

[0038] A display host; and

[0039] A head-mounted structure, the head-mounted structure includes a rear housing, a strap member, a conductive wire, and a first wire bundle member. A battery module is provided in the rear housing; one end of the strap member is slidably connected to the rear housing, and the other end is used to connect to the display host. The sliding direction of the strap member is parallel to the extending direction of the strap member; the conductive wire passes through the strap member, one end of the conductive wire is electrically connected to the battery module, and the other end is electrically connected to the display host. The conductive wire forms a bent portion in the rear housing; the first wire bundle member is provided in the rear housing, and at least a part of the structure is inserted into the bent portion. The first wire bundle member can also be driven when the strap member slides relative to the rear housing, so that the first wire bundle member remains in contact with the inner wall surface of the bent portion. One end of the strap member of the head-mounted structure away from the rear housing is connected to the display host, so that the head-mounted structure and the display host enclose a wearing space.

[0040] When the head-mounted structure of the technical solution of the present invention is applied to a head-mounted display device, one end of the strap member away from the rear housing can be connected to the display host, so that the head-mounted structure and the display host enclose a wearing space for the user's head to wear. At the same time, a battery module is arranged in the rear housing, and the battery module can be electrically connected to the display host through a conductive wire, so as to realize the power supply work for the display host. Among them, since one end of the strap member is slidably connected to the rear housing, it is possible to drive the strap member to slide relative to the rear housing, and then adjust the size of the wearing space enclosed by the head-mounted structure and the display host, so as to adapt to the wearing use of users with different head sizes. During this adjustment process, when the strap member slides, the conductive wire will be driven accordingly, and it is mainly reflected at the bending part. That is to say, after the strap member is stretched and slid, the bending part of the conductive wire will shrink accordingly to adapt to the distance between the display host and the battery in the rear housing after the strap member slides. At this time, since the head-mounted structure in this solution includes a first wire bundling member, the first wire bundling member is arranged in the rear housing and at least part of its structure is inserted into the bending part. When the strap member slides relative to the rear housing, the first wire bundling member can also be driven to keep it in a state of abutting against the inner wall surface of the bending part. Therefore, in this solution, when adjusting the size of the wearing space by driving the strap member to slide relative to the rear housing, the first wire bundling member is driven accordingly and always abuts against the inner wall surface of the bending part of the conductive wire. In this way, through the abutting and limiting of the inner wall surface of the bending part of the conductive wire by the first wire bundling member, the bending radius of the bending part can be kept unchanged and will not become too small due to following the sliding of the strap member, thus avoiding the problem of the conductive wire being damaged due to excessive bending, and improving the service life of the head-mounted display device.

[0063] Please refer to Figures 1 to 7, the present invention provides a head-mounted structure 100, which is applied to a head-mounted display device, specifically, it can be an AR device or a VR device, etc. The head-mounted display device further includes a display host. In an embodiment of the present invention, the head-mounted structure 100 includes a rear housing 10, a strap member 20, a conductive wire 30, and a first wire bundle member 40. A battery module 11 is provided in the rear housing 10; one end of the strap member 20 is slidably connected to the rear housing 10, and the other end is used to connect to the display host. The sliding direction of the strap member 20 is parallel to the extending direction of the strap member 20; the conductive wire 30 passes through the strap member 20. One end of the conductive wire 30 is electrically connected to the battery module 11, and the other end is electrically connected to the display host. The conductive wire 30 forms a bending portion 31 in the rear housing 10; the first wire bundle member 40 is provided in the rear housing 10, and at least a part of its structure is inserted into the bending portion 31. The first wire bundle member 40 can also be driven when the strap member 20 slides relative to the rear housing 10, so that the first wire bundle member 40 remains in contact with the inner wall surface of the bending portion 31.

[0064] The rear housing 10 can be used to raise the installation position for corresponding installation settings of the strap member 20, the conductive wire 30, the first wire bundle member 40, etc. Among them, in order to facilitate the subsequent use of the head-mounted structure 100, the rear housing 10 can fit closely to the user's head. The rear housing 10 can be an arc-shaped structure. The strap member 20 can be used to connect the rear housing 10 and the display host. Specifically, the number of the strap members 20 can be two. One end of each of the two strap members 20 is slidably connected to the rear housing 10, and the other end of each is connected to the opposite ends of the display host. In this way, through the connection of the two strap members 20 to the rear housing 10 and the display host, the head-mounted structure 100 and the display host can enclose a wearing space for the user's head to wear. Among them, the head-mounted structure 100 can further include an elastic member 50, and the elastic member 50 is connected between the rear housing 10 and the strap member 20. At this time, the elastic member 50 can be used to provide elastic force so that elastic expansion and contraction can occur between the strap member 20 and the rear housing 10, thereby realizing a certain adjustment of the size of the wearing space enclosed by the head-mounted structure 100 and the display host. At the same time, after adjustment, a certain elastic force can be applied to drive the head-mounted display device to be worn more stably on the user's head. The elastic member 50 can specifically be a spring, so that the elastic member 50 has good elasticity, which is conducive to ensuring that the head-mounted display device can be worn more stably after adjusting the size of the wearing space by stretching the strap member 20. At the same time, since the spring is usually a standard component, it is also convenient to purchase and obtain in the market. Of course, this application is not limited to this. In other embodiments, the elastic member 50 can also be an elastic rubber member or an elastic elastic band, etc., as long as it has corresponding elastic force. The conductive wire 30 can be used to be electrically connected to the battery module 11, and then pass through the strap member 20 and be electrically connected to the display host, thereby realizing the electrical conduction between the battery module 11 and the display host. In order to improve the convenience of use, the battery module 11 can be a rechargeable battery. At this time, a charging structure 12 can be provided at the position of the rear housing 10 corresponding to the battery module 11, so that after the power in the battery module 11 is used up, the battery module 11 can be charged through the charging structure 12 to realize recycling. In addition, the bent portion 31 of the conductive wire 30 can be used to form a movement margin, so that when the size of the wearing space is adjusted by stretching the strap member 20, the conductive wire 30 can be correspondingly released by reducing the bent portion 31, so as to adapt to the distance between the battery module 11 in the rear housing 10 connected to the rear end of the strap member 20 and the display host connected to the front end of the strap member 20. The number of the bent portions 31 can be one. At this time, the opening of the bent portion 31 can be the same as the sliding direction of the strap member 20; of course, it can also be perpendicular to the sliding direction of the strap member 20, that is, parallel to the thickness direction of the rear housing 10 as described below.In addition, the number of the bending portions 31 can also be at least two. In this case, the opening directions of every two adjacent bending portions 31 can be opposite, and the at least two bending portions 31 can be arranged in sequence in the thickness direction of the rear housing 10, or of course, can also be arranged in sequence in the sliding direction of the strap member 20. The first wire bundle member 40 can be used to abut against the inner wall surface of the bending portion 31, and when the strap member 20 is stretched, it can be driven to maintain the state of abutting against the inner wall surface of the bending portion 31, so as to ensure that the bending radius of the bending portion 31 remains unchanged, and the conductive wire 30 will not be damaged due to the bending transition when the conductive wire 30 slides following the stretching of the strap member 20. Among them, when the number of the bending portions 31 is at least two, in the extending direction of the conductive wire 30 among the at least two bending portions 31, mainly the bending portion 31 close to the strap member 20 undergoes a shrinking change to adapt to the stretching change of the strap member 20. Therefore, the first wire bundle member 40 can be mainly used to abut against the inner wall surface of the bending portion 31 arranged close to the strap member 20. That is, when there are a first bending portion 311 and a second bending portion 313 in the following text, since the first bending portion 311 is close to the strap member 20 in the extending direction of the conductive wire 30 and will undergo a shrinking change when the strap member 20 is stretched, the first wire bundle member 40 is mainly inserted into the first bending portion 311. In addition, it should also be noted that the first wire bundle member 40 can also be driven when the strap member 20 slides relative to the rear housing 10. It can be that the first wire bundle member 40 is driven to slide, or of course, can also be driven to deform, so as to ensure that the conductive wire 30 can be adapted between the battery module 11 and the display host after the strap member 20 is stretched and slides, and at the same time, the first wire bundle member 40 always abuts against the inner wall surface of the bending portion 31 to ensure that its bending radius will not become smaller.

[0065] When the head-mounted structure 100 of the technical solution of the present invention is applied to a head-mounted display device, the head-mounted structure 100 can be connected to the display host through one end of the strap member 20 away from the rear housing 10, so that the head-mounted structure 100 and the display host enclose a wearing space for the user's head to wear. At the same time, a battery module 11 is arranged in the rear housing 10, and the battery module 11 can be electrically connected to the display host through a conductive wire 30, so as to realize the power supply work for the display host. Among them, since one end of the strap member 20 is slidably connected to the rear housing 10, it is possible to drive the strap member 20 to slide relative to the rear housing 10, and then adjust the size of the wearing space enclosed by the head-mounted structure 100 and the display host, so as to adapt to the wearing use of users with different head sizes. During this adjustment process, when the strap member 20 slides, the conductive wire 30 will be driven accordingly, and it is mainly reflected at the bending portion 31. That is to say, after the strap member 20 is stretched and slid, the bending portion 31 of the conductive wire 30 will shrink accordingly to adapt to the distance between the display host and the battery in the rear housing 10 after the strap member 20 slides. At this time, since the head-mounted structure 100 in this solution includes a first wire bundling member 40, the first wire bundling member 40 is arranged in the rear housing 10, and at least part of its structure is inserted into the bending portion 31. When the strap member 20 slides relative to the rear housing 10, the first wire bundling member 40 can also be driven to keep it in a state of abutting against the inner wall surface of the bending portion 31. Therefore, in this solution, when the size of the wearing space is adjusted by driving the strap member 20 to slide relative to the rear housing 10, the first wire bundling member 40 is driven accordingly and always abuts against the inner wall surface of the bending portion 31. In this way, through the abutting and limiting of the inner wall surface of the bending portion 31 of the conductive wire 30 by the first wire bundling member 40, the bending radius of the bending portion 31 can be kept unchanged and will not become too small due to following the sliding of the strap member 20, thus avoiding the problem that the conductive wire 30 is damaged due to excessive bending, and improving the service life of the head-mounted display device.

[0066] Please refer to Figures 3 to 7 In an embodiment of the present invention, the first wire bundling member 40 is slidably arranged in the rear housing 10, and the sliding direction of the first wire bundling member 40 is parallel to the opening direction of the bending portion 31; the head-mounted structure 100 further includes a transmission component 60. When the strap member 20 slides relative to the rear housing 10, the strap member 20 drives the first wire bundling member 40 to slide through the transmission component 60, so that the first wire bundling member 40 keeps abutting against the inner wall surface of the bending portion 31.

[0067] In this embodiment, the first wire bundle 40 is slidably arranged, and the strap member 20 drives the first wire bundle 40 through the transmission assembly 60, so that the first wire bundle 40 can slide adaptively following the sliding of the strap member 20. At this time, the first wire bundle 40 does not exert a large abutting pressure on the bent portion 31 of the conductive wire 30, enabling the conductive wire 30 to be in a relatively natural bent state, which is conducive to further ensuring that the conductive wire 30 is not easily damaged. Of course, it should be noted that this application is not limited thereto. In other embodiments, when the conductive wire 30 can withstand a certain abutting pressure, the first wire bundle 40 can also be an elastic structure, which specifically may include an elastic sheet and an abutting block connected to the elastic sheet. The end of the abutting block away from the elastic sheet can abut against the inner wall surface of the bent portion 31. Thus, during the stretching and sliding process of the strap member 20, the bent portion 31 can shrink towards the opening direction of the device, and then the conductive wire 30 can drive the abutting block, forcing the abutting block to approach the elastic sheet and compress the elastic sheet. At this time, due to the elastic effect of the elastic sheet, the abutting block can always elastically abut against the inner wall surface of the bent portion 31, thereby ensuring that the bending radius of the bent portion 31 is not too small. In addition, it can also be seen from this that the first wire bundle 40 can be directly driven by the strap member 20 or driven by the conductive wire 30.

[0068] Further, please refer to Figures 3 to 7 , the opening direction of the bent portion 31 is the same as the sliding direction of the strap member 20 away from the rear housing 10. The strap member 20 is provided with a plurality of first engaging teeth 21, and the plurality of first engaging teeth 21 are arranged in sequence along the sliding direction of the strap member 20; the first wire bundle 40 is provided with a plurality of second engaging teeth 41, and the sequential arrangement direction of the plurality of second engaging teeth 41 is the same as the sequential arrangement direction of the plurality of first engaging teeth 21; the transmission assembly 60 is a gear set 61, and the gear set 61 is arranged in the rear housing 10 and meshes with the first engaging teeth 21 and the second engaging teeth 41, so that the strap member 20 drives the first wire bundle 40 to move in the same direction as the strap member 20 through the gear set 61.

[0069] In this embodiment, the opening of the bent portion 31 is arranged toward the direction in which the strap member 20 slides away from the rear housing 10, so that the sliding direction of the first harness member 40 can be the same as the sliding direction of the strap member 20, and thus a relatively simple transmission assembly 60 can be conveniently arranged to realize the driving of the first harness member 40 by the strap member 20. At this time, the transmission assembly 60 is arranged as a gear assembly 61, so that the strap member 20 can drive the first harness member 40 to slide in the same direction through the gear assembly 61. For example: when the strap member 20 is stretched and slides in the direction away from the rear housing 10, the conductive wire 30 and the first harness member 40 follow the strap member 20 and slide in the direction away from the rear housing 10. Among them, the multiple first meshing teeth 21 on the strap member 20 can be directly formed on the strap member 20, and of course, can also be formed by setting a rack on the strap member 20. Similarly, the plurality of second meshing teeth 41 on the first harness 40 can be directly formed on the first harness 40, or can be formed by providing a rack on the first harness 40. In addition, it should be noted that the present application is not limited thereto, and in other embodiments, when the opening of the bending portion 31 faces the inside or outside of the wearing space, the transmission assembly 60 can also be a combination of a sliding block and a connecting rod. At this time, the sliding block can be slidably arranged on the rear shell 10 along the thickness direction of the rear shell 10, and abut against the inner wall of the bending portion 31, and one end of the connecting rod is rotatably connected to the sliding block, and the other end is rotatably connected to the strap 20, and then when the strap 20 is stretched and slid, the block is driven by the connecting rod to slide accordingly to adapt to the abutment against the reduced inner wall surface of the bending portion 31.

[0070] Further, please refer to Figures 4 to 8 The gear set 61 includes a first gear 611, a second gear 613 and a third gear 615. The first gear 611 is rotatably disposed on the rear housing 10 and meshed with the first meshing tooth 21; the second gear 613 meshes with the first gear 611, and the pitch circle diameter of the second gear 613 is the same as the pitch circle diameter of the first gear 611; the third gear 615 is connected to the second gear 613 and is coaxially arranged with the second gear 613, and the pitch circle diameter of the third gear 615 is half of the pitch circle diameter of the second gear 613, and the third gear 615 is also meshed with the second meshing tooth 41.

[0071] In this embodiment, the gear set 61 is composed of a first gear 611, a second gear 613 and a third gear 615, so that when the strap 20 is stretched and slid, the first gear 611 can be driven to rotate counterclockwise, and the first gear 611 can drive the second gear 613 to rotate clockwise, and the third gear 615 is connected to the second gear 613 and is coaxially arranged. Therefore, the third gear 615 also rotates clockwise, and the third gear 615 rotating clockwise can drive the first cable tie 40 to slide along the direction in which the strap 20 is stretched, thereby realizing that the strap 20 drives the first cable tie 40 to move in the same direction through the gear set 61. Moreover, since the distance that the conductive wire 30 moves after the strap 20 is stretched and slid is twice the distance that the first harness 40 moves, the pitch circle diameter of the second gear 613 is set to be the same as the pitch circle diameter of the first gear 611, and the third pitch circle diameter is set to be half of the pitch circle diameter of the second gear 613, so as to ensure that after the first harness 40 moves a certain distance, the conductive wire 30 can move twice the distance in the corresponding bending portion 31, so as to ensure that the first harness 40 can always abut against the inner wall surface of the bending portion 31 during the movement of the conductive wire 30 following the strap 20. In addition, since the second gear 613 and the third gear 615 are distributed in sequence on the axis, the third gear 615 and the first gear 611 are staggered on the axis, and the first harness 40 and the first gear 611 are also staggered on the axis, so that the possibility of interference between the first harness 40 and the first gear 611 and the strap 20 is better avoided.

[0072] Please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 9 In one embodiment of the present invention, the first wiring harness 40 includes a contact column 43 and a transmission plate 45. The contact column 43 is inserted into the bending portion 31. The contact column 43 has a first contact surface 431 arranged in a circular arc shape. The first contact surface 431 abuts against the inner wall surface of the bending portion 31; the transmission plate 45 is connected to the end of the contact column 43 and extends along the sliding direction of the strap member 20 away from the rear shell body 10. A plurality of second meshing teeth 41 are arranged on the transmission plate 45.

[0073] In this embodiment, the first harness 40 can be adapted, inserted and abutted with the bending portion 31 through the abutment column 43, so that the first harness 40 can fully abut the inner wall surface of the bending portion 31 to improve the abutment and limiting effect on the bending portion 31. At the same time, because the transmission plate 45 is extended along the sliding direction of the strap 20, the transmission plate 45 can be used to set the plurality of second meshing teeth 41, so as to facilitate the sequential arrangement of the plurality of second meshing teeth 41 on the transmission plate 45. Among them, the abutment column 43 can be a cylindrical structure, and can also be a semi-cylindrical structure, so as to facilitate the first abutment surface 431 formed on the abutment column 43 to adapt and abut against the inner wall surface of the bending portion 31.

[0074] Further, please refer to Figure 4 , Figure 8 , Figure 9 , Figure 10 as well as Figure 11 The strap member 20 is provided with two rows of first meshing teeth 21, and the two rows of first meshing teeth 21 are arranged in sequence along the sliding direction of the strap member 20; there are two transmission plates 45, and the two transmission plates 45 are respectively connected to the opposite ends of the abutment column 43, and each transmission plate 45 is provided with a plurality of second meshing teeth 41 to form two rows of second meshing teeth 41; there are two gear sets 61, and each gear set 61 is meshed with a corresponding row of meshing teeth and a row of second meshing teeth 41.

[0075] In this embodiment, the two rows of first meshing teeth 21 and second meshing teeth 41 and the two transmission plates 45 are provided so that the first harness 40 can be connected to the belt member 20 through the transmission plates 45 at both opposite ends of the abutment column 43, so as to improve the stability of the belt member 20 driving the first harness 40. In addition, the abutment column 43 and the transmission plate 45 can be provided in an integrated structure, so that the connection strength between the abutment column 43 and the transmission plate 45 can be enhanced, so as to improve the overall strength of the first harness 40 and ensure that it can work normally and stably for a long time.

[0076] Please refer to Figures 3 to 6 In one embodiment of the present invention, the conductive wire 30 forms two bent portions 31 in the rear shell 10, and the head-mounted structure 100 can be enclosed with the display host to form a wearing space. The rear shell 10 is defined to have a thickness direction toward the wearing space, and the two bent portions 31 are distributed in sequence in the thickness direction of the rear shell 10; the opening direction of the two bent portions 31 is the same as the sliding direction of the strap 20 away from the rear shell 10 as the first bent portion 311, and the opening direction is opposite to the opening direction of the first bent portion 311 as the second bent portion 313; the abutment column 43 is inserted into the first bent portion 311, and the first abutment surface 431 abuts against the inner wall surface of the first bent portion 311.

[0077] In this embodiment, the conductive wire 30 forms two bending portions 31 inside the rear housing 10 and is sequentially distributed in the thickness direction of the rear housing 10. In this way, the number of bending portions 31 of the conductive wire 30 is relatively small, and thus it will not occupy a large space in the thickness direction of the rear housing 10. At the same time, the battery module 11 can also be arranged on one side of the multiple bending portions 31, avoiding occupying further space in the thickness direction of the rear housing 10. Therefore, the overall thickness of the rear housing 10 at this time does not need to be set too large, which is beneficial to reducing the overall volume of the rear housing 10 and improving the convenience of subsequent use. In addition, as described above, since among at least two bending portions 31 in the extending direction of the conductive wire 30, mainly the bending portion 31 close to the strap member 20 undergoes a shrinking change to adapt to the stretching change of the strap member 20, the first wire bundle member 40 can mainly be used to abut against the inner wall surface of the bending portion 31 arranged close to the strap member 20. That is, the abutting post 43 of the first wire bundle member 40 is inserted into the first bending portion 311, and the first abutting surface 431 is abutted against the inner wall surface of the first bending portion 311. Of course, it should be noted that this application is not limited thereto. In other embodiments, when there is a large accommodation space in the thickness direction of the rear housing 10, the number of the bending portions 31 can also be set to three or more. Or there is also one bending portion 31, and the opening of the bending portion 31 faces or deviates from the wearing space. At this time, the battery module 11 and the bending portion 31 can be sequentially arranged in the thickness direction of the rear housing 10.

[0078] Further, please refer to Figure 4 and Figure 6 , define the partial segment connecting the first bending portion 311 and the second bending portion 313 of the conductive wire 30 as the connecting segment 33. A limiting block 451 is provided on one side of the transmission plate 45 facing the middle of the abutting post 43, and the limiting block 451 abuts against the side of the connecting segment 33 facing the second bending portion 313.

[0079] In this embodiment, the transmission plate 45 can abut against the side of the connecting segment 33 facing the second bending portion 313 through the limiting block 451. When the first bending portion 311 of the conductive wire 30 moves following the strap member 20, the connecting segment 33 can be abutted and limited by the limiting block 451, avoiding the connecting segment 33 approaching the second bending portion 313 and causing wrinkles, and thus playing a certain role in limiting and maintaining the bending radius of the second bending portion 313. Among them, the limiting block 451 can be arranged in a long strip shape extending along the sliding direction of the transmission plate 45 to increase the abutting area with the connecting segment 33 and improve the abutting and limiting effect on it. Of course, the limiting block 451 can also be arranged at multiple intervals in the sliding direction of the transmission plate 45.

[0080] Further, please refer to Figure 12 andFigure 13 The head-mounted structure 100 further includes a second wire bundle member 70 disposed within the second bent portion 313 to keep the bending radius of the second bent portion 313 unchanged.

[0081] In this embodiment, the second wire bundle member 70 can play a more direct role in limiting and maintaining the bending radius of the second bent portion 313, making the bending radius of the second bent portion 313 more stable and further avoiding the possibility of excessive bending due to the stretching and sliding of the strap member 20. Among them, please refer to Figure 12 The second wire bundle member 70 is an elastic pad 71 (specifically, it can be a rubber pad or a silicone pad, etc.), and the elastic pad 71 is attached to the inner wall surface of the second bent portion 313. Thus, through the elastic abutting action of the elastic pad 71, the second bent portion 313 can tend to be maintained in a preset bent state. Of course, the present application is not limited to this. Please refer to Figure 12 and Figure 13 The second wire bundle member 70 can also be a limiting post 73. The limiting post 73 is connected to the rear housing 10, and the limiting post 73 has a second abutting surface 731 arranged in an arc shape, and the second abutting surface 731 abuts against the inner wall surface of the second bent portion 313. At this time, by the hard abutting of the limiting post 73 against the inner wall surface of the second bent portion 313, the second bent portion 313 can be kept in a state of abutting against the limiting post 73 to avoid further excessive bending and damage of the second bent portion 313.

[0082] Furthermore, please refer to Figure 5 and Figure 11 Define a partial segment of the conductive wire 30 connected to the first bent portion 311 as a first segment 35, and the first segment 35 is fixed to the strap member 20.

[0083] In this embodiment, fixing the first segment 35 to the strap member 20 can make the conductive wire 30 arranged more neatly and not easily wrinkle. Moreover, with this setting, it is also convenient for the strap member 20 to drive the conductive wire 30 to slide correspondingly when being stretched and slid. Similarly, please refer to Figure 3 and Figure 4, the partial segment of the conductive wire 30 connected to the second bent portion 313 is the second segment 37, and the second segment 37 can be fixed to the rear housing 10. Among them, in order to ensure the stability of the fixation of the first segment 35 and the second segment 37, and at the same time simplify the connection structure of the first segment 35 and the second segment 37, the first segment 35 and the second segment 37 can be adhesively fixed to the strap member 20 and the rear housing 10 respectively. Further, in order to ensure the accuracy of the installation of the first segment 35 and the second segment 37 on the strap member 20 and the rear housing 10, one of the first segment 35 and the strap member 20 can be provided with a first positioning post 23, and the other can be provided with a first positioning hole 351, so as to realize the positioning installation of the first segment 35 on the strap member 20 through the insertion and cooperation of the first positioning post 23 and the first positioning hole 351. Similarly, one of the second segment 37 and the rear housing 10 can be provided with a second positioning post 13, and the other can be provided with a second positioning hole 371, so as to realize the positioning installation of the second segment 37 on the rear housing 10 through the insertion and cooperation of the second positioning post 13 and the second positioning hole 371.

[0084] Please refer to Figure 4 , Figure 6 , Figure 8 and Figure 10 , in an embodiment of the present invention, a first guiding groove 15 is provided in the rear housing 10, and the first guiding groove 15 extends along the sliding direction of the first wire bundle member 40. A first guiding block 453 is provided on a side of the transmission plate 45 away from the middle of the abutting post 43, and the first guiding block 453 is inserted into the first guiding groove 15.

[0085] In this embodiment, through the guiding cooperation of the first guiding block 453 and the first guiding groove 15, the first wire bundle member 40 can only slide along the extending direction of the first guiding groove 15, which is beneficial to improving the stability of the movement of the first wire bundle member 40. Similarly, please refer to Figure 6 , Figure 8 , Figure 9 and Figure 10 , in order to improve the stability of the movement of the strap member 20, a second guiding groove 17 is further provided in the rear housing 10. One end of the strap member 20 away from the display host can be slidably inserted into the rear housing 10. The second guiding groove 17 extends along the sliding direction of the strap member 20. The strap member 20 inserted into the rear housing 10 is provided with a second guiding block 25, and the second guiding block 25 is inserted into the second guiding groove 17.

[0086] The present invention also provides a head-mounted display device, which includes a display host and a head-mounted structure 100. The specific structure of the head-mounted structure 100 refers to the above embodiments. Since this head-mounted display device adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.
