DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 and Figure 2 In one embodiment of the utility model application, a back head pad 10 of a head mounted device is disclosed, wherein the head mounted device comprises an annular shell 20 and a signal module 30, the area of ​​the annular shell 20 that contacts the forehead of the human body is a first end 21, and the area that contacts the back of the human body is a second end 22; the signal module 30 is arranged at the first end 21; the back head pad 10 comprises a connecting portion 11 and a contact portion 12, one side of the connecting portion 11 is detachably connected to the second end 22, and the other side is connected to the contact portion 12, and the contact portion 12 is used to fit the back of the human body; the hardness of the connecting portion 11 is greater than the hardness of the contact portion 12.

[0028] The head-mounted device disclosed in this embodiment is a device worn on the user's head to achieve functions. It can be a display device such as a virtual reality device, an augmented reality device, a mixed reality device, or a head massager, a head physiotherapy device, a head energy warehouse, etc. The head-mounted device can achieve a variety of different effects by sending optical signals, acoustic signals, tactile signals, etc. to the user's head to meet people's entertainment, medical, learning, work, etc. The types of head-mounted devices in this embodiment are only exemplified, not exhaustive. Other types of head-mounted devices, as equivalent replacements for the technical concept in this embodiment, should also be within the scope of protection of this application.

[0029] Specifically, the head-mounted device disclosed in this embodiment is in an annular shape as a whole, replacing the traditional helmet shape, thereby improving the breathability during use, reducing the weight of the device, and helping to reduce the wearing pressure of the user.

[0030] When wearing the device, the annular shell 20 is put on the user's head. At this time, the signal module 30 is aligned with and contacts the position of the human forehead, and can interfere with or collect signals at the position of the human forehead. Specifically, the signal module 30 can use sound components such as speakers and sound boxes, or can use pressing components such as massage heads and massage claws, or can use signal sensing components such as electrode heads and sensor heads, so as to bring different feelings to the customer's head according to different functions.

[0031] Specifically, when the shape of the annular shell 20 matches the user's head shape, the fixation can be completed directly, which is convenient for the user to use the device directly, eliminating the adjustment process and facilitating use. When the shape of the annular shell 20 does not match the user's head shape, problems such as device offset and poor contact between the signal module 30 and the forehead are likely to occur. Therefore, the back head pad 10 is assembled at the second end 22, and the connection portion 11 with high hardness faces the second end 22 and is connected, so that the back head pad 10 and the annular shell 20 are connected as a whole and remain stable; the contact portion 12 with low hardness is in close contact with the back of the head, thereby reducing the gap between the head and the head-mounted device, so as to achieve the effect of complete fit between the head-mounted device and the head and improving the contact stability.

[0032] In addition, the connecting portion 11 has high hardness and stable shape, so even when the back head pad 10 is squeezed, it can maintain its basic shape and maintain a stable connection with the annular shell 20; the contact portion 12 can be attached to the connecting portion 11 by double-sided tape or glue. The contact portion 12 has low hardness and a soft touch when attached to the head, which reduces the pressure on the head position and improves the comfort of wearing the device; in addition, the back head pad 10 is tightly attached to the head and presses against the second end 22, so that the annular shell 20 is subjected to a backward supporting force, and the signal module 30 located at the first end 21 therefore tends to be tightly attached to the forehead of the human body, thereby improving the stability of the signal module 30 when used.

[0033] In short, by providing the back head pad 10, the wearing method of the head-mounted device is simplified, the adjustment steps are reduced while maintaining stability, the wearing comfort is improved, and the stability and convenience of the device are increased.

[0034] like Figure 1 and Figure 2 As shown, as an implementation of this embodiment, it is disclosed that the second end portion 22 includes an assembly platform 221 arranged opposite to the first end portion 21, and an arc-shaped connecting section 222 arranged on both sides of the assembly platform 221 for connecting the first end portion 21; an assembly groove 111 is provided on the side of the connecting portion 11 facing the second end portion 22, and the assembly groove 111 includes a middle groove 1111 opening toward the assembly platform 221 and an edge groove 1112 opening toward the arc-shaped connecting section 222; the middle groove 1111 is a strip groove, and the edge groove 1112 is an arc groove.

[0035] In this embodiment, the back head pad 10 is assembled on the inner side of the annular shell 20, and the middle groove 1111 is aligned with the assembly platform 221, and the edge groove 1112 is aligned with the arc-shaped connecting section 222, so as to achieve a close fit between the back head pad 10 and the second end 22, increase the contact area, and improve the contact stability. Moreover, the arc-shaped wall of the arc-shaped connecting section 222 forms a clamping state for the back head pad 10 from the side to prevent the back head pad 10 from shifting to the left and right sides, thereby improving the stability of the back head pad 10 during assembly. When worn, the back of the human head is tightly attached to the contact portion 12, and the back head pad 10 is subjected to pressure toward the second end 22, thereby further improving the stability of the connection with the annular shell 20. In addition, the middle position of the assembly groove 111 is a strip groove, and the two sides are arc grooves, and the whole is arched, so the assembly with the second end 22 is a special-shaped pairing, so the assembly direction is fixed, it is not easy to operate incorrectly, and the accuracy of assembly is improved.

[0036] It can be seen that the disassembly and assembly method of the back head pad 10 and the annular shell 20 in this embodiment is simple, and only requires alignment and plugging. After assembly, the back head pad 10 and the annular shell 20 are connected as a whole, with good structural stability and no need for additional fixing accessories. Therefore, it is easy to operate and is conducive to promotion and use.

[0037] like Figure 3 As shown, as another implementation of this embodiment, the connection portion 11 includes a first limiting portion 112 and a second limiting portion 113, and the first limiting portion 112 and the second limiting portion 113 are relatively arranged on both sides of the assembly groove 111, and are used to clamp the second end portion 22. In this embodiment, the first limiting portion 112 and the second limiting portion 113 are in contact with the second end portion 22 to limit the movement of the back head pad 10 in the up and down directions, avoid the back head pad 10 from being offset during assembly and use, and further improve the stability of the back head pad 10 in use.

[0038] Specifically, as another implementation of this embodiment, it is disclosed that the width of the first limiting portion 112 gradually decreases from the middle groove 1111 toward the edge groove 1112. The first limiting portion 112 disclosed in this embodiment is arranged on the side of the assembly groove 111, so the assembly position will be blocked during the assembly process, and the entire assembly groove 111 is arched, and the width of the first limiting portion 112 is set to be wide in the middle and narrow at both ends, which can reduce the blocking of the second end portion 22 in the assembly groove 111 while maintaining the limiting function, so as to facilitate observation and rapid accurate positioning and assembly.

[0039] Similarly, the width of the second limiting portion 113 gradually decreases from the middle groove 1111 toward the edge groove 1112. The second limiting portion 113 disclosed in this embodiment is arranged on the side of the assembly groove 111, and the width of the second limiting portion 113 is set to be wide in the middle and narrow at both ends, which can reduce the obstruction of the second end portion 22 in the assembly groove 111 while maintaining the limiting function, so as to facilitate observation, rapid and accurate positioning, and assembly.

[0040] Specifically, the shape of the first limiting portion 112 and the shape of the second limiting portion 113 can be set to be completely the same, so as to facilitate mold manufacturing. In addition, it is beneficial to improve the symmetry of the overall structure of the back head pad 10, so that the two ends of the back head pad 10 are not divided into left and right and up and down, and can be turned 180 degrees for free assembly, thereby improving the convenience of using the back head pad 10.

[0041] Specifically, as another implementation of this embodiment, an anti-skid layer is disclosed in the assembly groove 111. In this embodiment, the assembly groove 111 contacts the second end 22. The annular shell 20 of the head-mounted device is generally a plastic shell or an alloy shell with a smooth surface. The anti-skid layer can further improve the stability of the back head pad 10 assembled on the second end 22 and reduce the risk of dislocation, sliding or falling off.

[0042] Specifically, as another implementation of this embodiment, the anti-slip layer is disclosed to be any one of a felt cloth layer, a silicone layer, a latex layer, and a rubber layer. The anti-slip layer is provided to increase the roughness of the surface contact, thereby increasing the friction between the back head pad 10 and the annular shell 20 and improving the reliability of the connection.

[0043] Specifically, as another implementation of this embodiment, it is disclosed that the thickness of the contact portion 12 gradually decreases from the center to the edge. The annular shell 20 disclosed in this embodiment is worn on the user's head. According to the characteristics of the human head, the position where the gap is most likely to be generated is at the back of the head. Extending from the back of the head to both sides, the gap between the annular shell 20 and both sides of the head gradually decreases. Therefore, the contact portion 12 on the back of the head pad 10 that contacts the head is set to a flexible structure with a thick center and a thin edge to ensure that the back of the head pad 10 is in full contact with the user's head, but will not generate excessive squeezing force to avoid affecting the wearing comfort.

[0044] Specifically, as another implementation of this embodiment, it is disclosed that the connecting portion 11 is any one of a hard plastic plate, a metal plate, an aluminum alloy plate, and a carbon fiber plate. In this embodiment, the connecting portion 11 needs to maintain a stable shape during assembly and use to maintain a firm connection with the annular body, so the connecting portion 11 made of hard plastic, iron plate, aluminum alloy, carbon fiber and other materials is used, which has the advantages of stable structure, good mechanical properties, and not easy to deform, which is conducive to maintaining the shape of the back head pad 10 for long-term use.

[0045] Specifically, as another implementation of this embodiment, the contact portion 12 is disclosed to be any one of a sponge pad, a latex pad, a rubber pad, a silicone pad, and a polyurethane soft pad. In this embodiment, the contact portion 12 is used to fit the back of the human head, so as to avoid hard collision injuries. Soft materials such as sponge, latex, rubber silicone, polyurethane, etc. are set, and can be made by a foaming process to achieve a soft touch and enhance the user's wearing experience.

[0046] like Figure 3 As shown, as another implementation of this embodiment, it is disclosed that the back of the head pad 10 also includes an outer soft cover 13, the edge of the outer soft cover 13 is sewn and spliced ​​with the connecting portion 11 to form an inner chamber, and the contact portion 12 is arranged in the inner chamber. Since the back of the head pad 10 disclosed in this embodiment contacts the human skin, dirt is likely to remain during repeated use. The outer soft cover 13 is provided to wrap the contact portion 12 to reduce direct contact of the contact portion 12, which is beneficial to extend the service life of the contact portion 12. The outer soft cover 13 can be washed repeatedly to improve the cleanliness of the back of the head pad 10 during use.

[0047] Specifically, as another implementation of this embodiment, it is disclosed that the outer soft cover 13 is any one of a latex leather cover, a rubber leather cover, a nylon leather cover, and an imitation leather cover. The use of latex or rubber with a soft surface to make the leather cover can further improve the touch of the surface of the back head pad 10; nylon leather cover and imitation leather cover can also be used as external soft covers to protect the contact part 12. It should be noted that this embodiment only cites the types of outer soft covers 13, but the protection scope of the utility model is not limited to this. As long as other types of outer soft covers 13 can achieve the technical effects disclosed in this application, they should also be within the scope of protection of this application as equivalent replacements of the concept of the utility model.
