[0032] See also Figure 1 and Figure 2 An embodiment of the present invention proposes a head-mounted pressure-sensing structure 100, comprising a first elastic covering layer 110, a flexible pressure-sensing layer 120 and a second elastic covering layer 130; the flexible pressure-sensing layer 120 is arranged between the first elastic covering layer 110 and the second elastic covering layer 130, and the flexible pressure-sensing layer 120 includes a plurality of pressure sensors 122 arranged along a first direction and a second direction, and the pressure sensors 122 are used to detect the pressure on the head of the user when wearing the head.

[0033] According to the head-mounted pressure sensing structure 100 proposed in the above embodiment, the first elastic covering layer 110 or the second elastic covering layer 130 is in direct contact with the wearer's skin. Based on the elastic characteristics of the first elastic covering layer 110 and the second elastic covering layer 130, the user's wearing comfort can be improved. Then, the pressure on the user is detected in real time by the pressure sensor 122 arranged in the flexible pressure sensing layer 120. In this way, by real-time detection and collection of head pressure data when the user wears the head-mounted device, the detection data is provided for the head-mounted device, which can make the head-mounted device design more scientific and provide better wearing comfort.

[0034] In one embodiment, the distance between two adjacent pressure sensors 122 is 1 mm-12 mm.

[0035] In this embodiment, "adjacent" refers to two pressure sensors 122 that are close to each other in the first direction, or two pressure sensors 122 that are close to each other in the second direction. In this way, the density of the pressure sensors 122 can be kept within a suitable range, which can avoid waste of resources caused by excessive concentration of the pressure sensors 122, and can also avoid sparse pressure sensors 122 affecting the pressure detection result.

[0036] Optionally, the distance between two adjacent pressure sensors 122 is 1 mm, 2 mm, 3 mm, 4 mm or 5 mm.

[0037] In one embodiment, the first elastic cover layer and / or the second elastic cover layer is an antibacterial and antiperspirant fabric.

[0038] It is understandable that head-mounted devices, as devices that are in close contact with the human head, are often corroded by human sweat, and because they involve sensitive electronic components inside, they are inconvenient to clean. Therefore, long-term use will cause local mildew and serious facial infection. The technical solution of this embodiment can improve the user experience, protect physical and mental health, and also increase the service life of the device.

[0039] In one embodiment, the first elastic cover layer 110 and / or the second elastic cover layer 130 are polyurethane, nylon, Lycra or Modal.

[0040] The first elastic covering layer 110 or the second elastic covering layer 130 is made of the material in this embodiment, and has good elasticity and flexibility.

[0041] Optionally, the first elastic covering layer 110 and the second elastic covering layer 130 are woven from the above materials.

[0042] In one embodiment, the thickness of the first elastic cover layer 110 and / or the second elastic cover layer 130 is 1 mm-5 mm.

[0043] In this embodiment, the thickness of the first elastic covering layer 110 and the second elastic covering layer 130 is set within the range of 1 mm to 5 mm, which can prevent the user from directly feeling the structure of the flexible pressure-sensitive layer 120 when the first elastic covering layer 110 and the second elastic covering layer 130 are too thin, thereby affecting the user experience; it can also prevent the first elastic covering layer 110 and the second elastic covering layer 130 from affecting the detection effect of the pressure sensor 122 when they are too thick.

[0044] In one embodiment, the first elastic covering layer 110, the flexible pressure-sensitive layer 120, and the second elastic covering layer 130 are connected by sewing or gluing.

[0045] It is understandable that in this embodiment, the first elastic covering layer 110, the flexible pressure-sensitive layer 120 and the second elastic covering layer 130 are connected by sewing or gluing, and there is no need to set a connecting structure on the surface of the first elastic covering layer 110 and the second elastic covering layer 130, thereby affecting the user's touch.

[0046] An embodiment of the present invention further provides a head-mounted device, comprising the head-mounted pressure-sensing structure 100 provided according to any of the above embodiments.

[0047] In this embodiment, the head-mounted device includes but is not limited to VR devices and headphones.

[0048] In one embodiment, the head-mounted device includes a first cover for covering the facial area of ​​the user, two second covers for covering the ear area of ​​the user, and at least one third cover for covering the top area of ​​the user's head, and the first cover, the second cover and the third cover are all formed by extending the head-mounted pressure-sensing structure 100.

[0049] In this embodiment, the pressure of the user's facial area, ear area and top of the head area is detected through the first covering piece, the second covering piece and the third covering piece, so that most of the acupuncture points on the user's head can be covered, reflecting the comprehensiveness of the pressure detection of the head-mounted device and further ensuring the safety of the user's head.

[0050] In a specific embodiment, the number of pressure sensors 122 on the first cover is (2-32)×(2-32); the number of pressure sensors 122 on the second cover is (2-32)×(2-18); and the number of pressure sensors 122 on the third cover is (2-16)×(2-18).

[0051] Optionally, the number of the pressure sensors 122 on the first cover is 32×32, that is, in the first direction, the pressure sensors 122 have 32 columns, and in the second direction, the pressure sensors 122 have 32 rows.

[0052] Optionally, the number of pressure sensors 122 on the second cover is 32×18.

[0053] Optionally, the number of pressure sensors 122 on the third cover is 16×18.

[0054] Further, the number of the third covering members is four, and the four third covering members are symmetrically arranged.

[0055] In a more specific embodiment, a first through hole is formed on the first cover member, and the first through hole is used to expose the user's eyes. A second through hole is formed on the second cover member, and the second through hole is used to expose the user's ears.

[0056] In a feasible implementation, the density of the pressure sensors 122 around the first through hole is greater than the density of the pressure sensors 122 in other parts. With such a design, the pressure on the eyes of the user when wearing the head mounted device can be detected as much as possible, thereby improving the safety of the user's eyes.

[0057] Of course, the same is true for the ear area.

[0058] In another embodiment of the present invention, the head mounted device further includes a collection unit, a processing unit and a feedback unit. The collection unit is used to collect current information of the pressure sensor 122; the processing unit is used to process the current information and output the pressure information; the feedback unit is used to modify the preset parameters and feed back to the pressure sensor 122.

[0059] In this embodiment, the current signal generated by the pressure sensor 122 when in contact with the user's skin is transmitted to the acquisition unit, and the acquisition unit transmits these current signals to the processing unit. The processing unit processes and analyzes these current signals and converts them into pressure information. After receiving the pressure information, the feedback unit modifies the preset parameters in the pressure sensor 122 and feeds back to the pressure sensor 122. After the preset parameters are modified, the pressure sensor 122 transmits the corresponding current information to the acquisition unit again. The processing unit processes and compares the current information twice or more to obtain pressure information close to the actual situation.

[0060] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
