[0042] At present, the virtual reality industry is in a period of rapid growth, and users need to wear head-mounted devices in the process of experiencing virtual reality. A competitive head-mounted device not only needs to be the best in performance, but also needs to consider the wearing experience of users. The existing head-mounted devices usually have a headband structure. In the case of correct wearing, the headband structure will apply most of the weight of the head-mounted device to the top of the head, thereby reducing the pressure on the nose bridge and ears. However, such a headband structure is usually not adjustable, so that the head-mounted device can only be suitable for some users with a relatively common head circumference, and for some users with a larger or smaller head circumference, it will cause discomfort and affect the user experience.

[0043] In view of this, the present application provides a head-mounted device to solve the problem that the headband structure of the existing head-mounted device cannot be adjusted, causing some users with a larger or smaller head circumference to wear uncomfortably, Figures 1 to 8 An embodiment of the head-mounted device provided by the present application is an electronic device with a headband. Therefore, the present design does not limit the specific type of the head-mounted device. In the embodiment of the present application, the head-mounted device is a VR glasses.

[0044] Please refer to Figures 1 to 3 The head-mounted device 100 includes a housing 1, a headband 2, an adjusting device 3, a pressure detection device 4, and a control device. The housing 1 defines a wearing space 13 for a user to wear, and has a receiving groove 121 formed therein. The headband 2 has two mounting ends 21 mounted in the housing 1, and a middle section 22 connecting the two mounting ends 21. The middle section 22 is rotatable relative to the two mounting ends 21. The middle section 22 has a receiving position that is rotated and received into the receiving groove 121 of the housing 1, and a wearing position that is rotated out of the receiving groove 121 upward. The adjusting device 3 is arranged in the housing 1 corresponding to at least one mounting end 21. The adjusting device 3 is arranged to act on the mounting end 21 to adjust the length of the middle section 22. The pressure detection device 4 is arranged on the headband 2 to detect the pressure value of the headband 2. The control device is electrically connected with the pressure detection device 4 and the adjusting device 3 to control the adjusting device 3 to work according to the pressure value.

[0045] The technical scheme provided by the application has the advantages that, since the pressure detection device 4 is arranged on the headband 2, when a user wears the headband 2 on the head, the control device can control the adjusting device 3 to act according to the pressure value detected by the pressure detection device 4, so as to adjust the tightness of the middle section 22 of the headband 2, to adapt to users with different head circumferences, and improve the experience of the user. Furthermore, since the accommodating groove 121 is arranged on the shell 1, the middle section 22 of the headband 2 can be rotated to the storage position, that is, accommodated in the accommodating groove 121, when not in use, so that the headband 2 can be hidden, which is not only beautiful but also saves space, and does not entangle other external cables or hanging ropes and the like, is convenient to store, simple and practical, and is suitable for mass production.

[0046] Further, in the embodiment of the application, the control device comprises a memory, a processor and a control program of the head-mounted device stored in the memory, and the processor executes the control program of the head-mounted device to implement the control method of the head-mounted device 100 as follows:

[0047] obtaining the pressure value of the pressure detection device 4;

[0048] when the pressure value is less than the first boundary value, controlling the adjusting device 3 to act to drive the middle section 22 to contract through the mounting end 21;

[0049] when the pressure value is greater than the second boundary value, controlling the adjusting device 3 to act to drive the middle section 22 to elongate through the mounting end 21;

[0050] wherein the second boundary value is greater than the first boundary value.

[0051] When the pressure value is less than the smaller first boundary value, it means that the pressure borne by the headband 2 is too small, and the middle section 22 is too loose, that is, the pressure borne by the nose bridge and the ears of the user is large, and it is determined that the wearing is too loose, and the control device controls the adjusting device 3 to act, so as to drive the middle section 22 to contract through the mounting end 21 to concentrate the main weight on the top of the head, so that the user wears comfortably. When the pressure value is greater than the larger second boundary value, it means that the pressure borne by the headband 2 is too large, and the middle section 22 is too tight, that is, the pressure borne by the nose bridge and the ears of the user is small, and the pressure borne by the top of the head is too large, and it is determined that the wearing is too tight, and the control device controls the adjusting device 3 to act, so as to drive the middle section 22 to elongate through the mounting end 21 to release the pressure, so that the head-mounted device 100 falls to the position of the nose bridge and the ears, and part of the weight is distributed to the nose bridge and the ears, so that the user wears comfortably.

[0052] The accommodating groove 121 is used to accommodate the middle section 22 of the top band 2. The accommodating groove 121 can be arranged in various positions, for example, on the side of the shell 1 away from the wearing space 13, so that when the adjusting device 3 adjusts the mounting end 21 to contract, the middle section 22 can be stably tensioned and accommodated in the accommodating groove 121, and will not accidentally fall out. However, the top band 2 is usually arranged on the upper side of the shell 1 to be pulled upward, which needs to be wound to the back side of the shell 1, which is not beautiful and inconvenient to turn over. Therefore, please refer to Figure 2 and Figure 3 In this embodiment, the accommodating groove 121 is arranged on the upper side of the shell 1. By directly arranging the accommodating groove 121 on the upper side of the shell 1, the middle section 22 can be directly corresponded, so that the middle section 22 can be conveniently accommodated in the accommodating groove 121, and the middle section 22 has no exposed part, and the whole is more beautiful. It can be understood that the two ends of the middle section 22 are arranged corresponding to the two ends of the accommodating groove 121 respectively.

[0053] As described above, the top band 2 can be rotated upward when subjected to a certain pulling force from the outside, and can be separated from the accommodating groove 121, or can be driven to rotate to a predetermined position by the electric drive arranged in the head-mounted device 100 based on the electric signal instruction sent by the control device or the adjusting device 3, and can be separated from or accommodated in the accommodating groove 121.

[0054] Since the pressure detection device 4 is further arranged on the middle section 22, when the head-mounted device 100 is not used, the pressure detection device 4 needs to be released as much as possible to ensure the service life of the pressure detection device 4. Therefore, please refer to Figure 2 and Figure 3 In this embodiment, the accommodating groove 121 is formed with a recess groove 1211 corresponding to the side wall of the pressure detection device 4. When the top band 2 is in the accommodation position, the recess groove 1211 is used to accommodate the pressure detection device 4. The recess groove 1211 provides sufficient space for the pressure detection device 4, which can ensure the release of the pressure detection device 4 when the head-mounted device 100 is not used, avoids the pressure detection device 4 from being in contact with the side wall of the accommodating groove 121, and improves the service life of the pressure detection device 4.

[0055] The adjusting device 3 can adjust the length of the middle section 22 through the mounting end 21 in various ways. For details, please refer to Figure 4 The adjusting device 3 comprises a retracting device 31 connected to at least one mounting end 21, which is arranged to adjust the length of the middle section 22 by retracting and releasing the mounting end 21. The length of the middle section 22 is adjusted by the mounting end 21 through the retracting and releasing action of the retracting device 31.

[0056] The structure of the winding and unwinding device 31 is also various, specifically, please refer to Figure 4 and Figure 5 In the embodiment, the winding and unwinding device 31 comprises a winding shaft 311 and a driving motor 32, the winding shaft 311 is rotationally arranged in the shell 1, both the mounting ends 21 are arranged on the winding shaft 311 and are respectively located at both sides of the winding shaft 311 in the radial direction; and the driving motor 32 is electrically connected to the control device, the driving motor 32 has an output shaft, and the output shaft is drivingly connected to the winding shaft 311. Through the control of the control device on the driving motor 32, when the pressure value detected by the pressure detection device 4 is too small, the driving motor 32 drives the winding shaft 311 to act in the forward direction, so as to realize the contraction of the intermediate section 22; when the pressure value detected by the pressure detection device 4 is too large, the driving motor 32 drives the winding shaft 311 to act in the reverse direction, so as to realize the relaxation of the intermediate section 22.

[0057] In other embodiments, the winding and unwinding device 31 can also comprise a rack, a gear and the driving motor 32, the rack is arranged on the mounting end 21, the gear is arranged on the output shaft of the driving motor 32, the gear is meshingly connected with the rack, and the extension and contraction adjustment of the intermediate section 22 can also be realized by controlling the forward and reverse rotation of the driving motor 32, which will not be described herein.

[0058] The connection mode of the driving motor 32 and the winding shaft 311 can be indirect connection or direct connection, which can be correspondingly arranged according to the overall space in the shell 1, specifically, the winding shaft 311 and the output shaft of the driving motor 32 are arranged in axial alignment, one of them is formed with a matching recess, and the other is formed with a shaft coupling convex part, the shaft coupling convex part is adaptively connected with the matching recess, so as to transmit the driving force of the driving motor 32 to the winding shaft 311.

[0059] Further, please refer to Figures 4 to 7 In the embodiment, the winding shaft 311 is formed with two axially spaced ring grooves 3111, and the two mounting ends 21 are respectively arranged in the corresponding ring grooves 3111. Compared with the adjustment of a single mounting end 21, the simultaneous arrangement of the two mounting ends 21 on the winding shaft 311 can improve the adjustment efficiency, that is, under the same rotation angle of the winding shaft 311, the simultaneous arrangement of the two mounting ends 21 on the winding shaft 311 can obtain double adjustment amount, and in addition, the ring groove 3111 can limit the mounting end 21 therein, avoiding the mutual entanglement of the two mounting ends 21.

[0060] The connection mode of the mounting end 21 and the winding shaft 311 can be various, for example, welding and riveting can be used for connection, please refer to Figure 8In the embodiment, the unwinding shaft 311 is formed with two axially spaced and radially through limiting counterbores 3112, and the two mounting ends 21 are respectively clamped in the corresponding limiting counterbores 3112. The mounting end 21 is clamped in the limiting counterbores 3112 in a non-fixed form, which reduces the complexity of installation and assembly. It should be noted that the mounting end 21 can be clamped in the limiting counterbores 3112 in many forms. For example, the mounting end 21 can be knotted and positioned after being passed through the limiting counterbores 3112, or the mounting end 21 can be unfolded after being passed through the limiting counterbores 3112 by setting a retreat-stop structure on the mounting end 21. The embodiment of the present application does not limit this.

[0061] Specifically, in order to increase the connection stability of the unwinding shaft 311 and the mounting end 21, please continue to refer to Figure 8 In the embodiment, the limiting counterbores 3112 are arranged in a bent form. In an example, the bent form can be S-shaped. This design can effectively increase the contact area of the mounting end 21 and the limiting counterbores 3112, can avoid the mounting end 21 from being pulled out of the limiting counterbores 3112 due to excessive force, and ensures the reliability of the structure.

[0062] In order to ensure that the mounting end 21 of the top strap 2 can smoothly move in the shell 1, in the embodiment, a guide structure 5 is arranged in the shell 1 corresponding to the two mounting ends 21. The guide structure 5 includes a guide base 51 and a matching cover plate 52. The matching cover plate 52 is arranged on the guide base 51 to define a limiting passage extending in the transverse direction. The two ends of the limiting passage are respectively arranged corresponding to the unwinding shaft 311 and the middle section 22. The mounting end 21 is arranged in the corresponding limiting passage. The limiting passage can smoothly guide the mounting end 21, avoid the mounting end 21 from being excessively bent, and ensure the service life of the mounting end 21.

[0063] It should be noted that the top strap 2 is mounted on the shell 1, and the included angle of the middle section 22 relative to the human body can have many choices. For example, the middle section 22 can be arranged in front of and behind the human body, or the middle section 22 can be arranged to the left and right of the human body. The embodiment of the present application does not limit this.

[0064] In a specific embodiment, the shell 1 includes a front shell 11 and a rear shell 12 which are spliced together. The front shell 11 is provided with an optical system and other main parts. The top strap 2, the adjusting device 3 and the control device are arranged in the rear shell 12.
