[0032] This invention proposes a headrest 100.

[0033] Reference Figures 1 to 3The headrest 100 of the present invention includes a rear island 1 (covering the back of the user's head, also referred to as a head pad, cushion, pillow, battery compartment or back headband), a left pillow 2 and a right pillow 3. The rear island 1 is worn on the outside of the user's occipital bone by a strap 201. The left pillow 2 is located on the side of the rear island 1 facing the occipital bone, and the right pillow 3 is located on the side of the rear island 1 facing the occipital bone and is arranged side by side with the left pillow 2. At least one of the left pillow 2 and the right pillow 3 is configured to be adjustable in position on the rear island 1.

[0034] An embodiment of the headrest 100 of the present invention includes a rear island 1, which is crescent-shaped and has straps 201 connected to both ends, allowing it to be worn on the user's head. Unlike a traditional single-piece headrest 100, the present invention has symmetrical left and right occipital pieces 2 and 3 on the side of the rear island 1 facing the occipital bone, for fitting against the occipital bone. The positions of the left and / or right occipital pieces 2 and 3 are movable. For example, the left and / or right occipital pieces 2 and 3 can be magnetically attached to different positions on the rear island 1, or they can be attached to different positions on the rear island 1 using Velcro, or they can slide to different positions along the length or width of the rear island 1 using a sliding rail.

[0035] The left pillow piece 2 can be moved left and right or up and down, or both. Similarly, the right pillow piece 3 can be moved left and right or up and down, or both. The positions of the left pillow piece 2 and the right pillow piece 3 can be adjusted independently or simultaneously.

[0036] Therefore, users can adjust the left pillow piece 2 and / or the right pillow piece 3 to a suitable position according to their own needs, thereby changing the relative position and relative distance between the left pillow piece 2 and the right pillow piece 3. Regardless of the wearer's ethnicity, two suitable positions can be found to achieve stable support for the occipital bone, thus adapting to the wearing needs of different ethnicities, overcoming the shortcomings of traditional head pillows, improving the universality of head pillows, and facilitating the global market for head pillows.

[0037] In some embodiments of the present invention, the left pillow piece 2 is positioned adjustablely on the rear island 1 in a direction away from or close to the right pillow piece 3.

[0038] In another embodiment, the right bolster 3 is positioned adjustablely on the rear island 1 in a direction away from or close to the left bolster 2.

[0039] In another embodiment, the left bolster 2 and the right bolster 3 are positioned adjustablely on the rear island 1 in directions away from or close to each other.

[0040] The left pillow piece 2 and / or the right pillow piece 3 are adjusted in such a way that the left pillow piece 2 and / or the right pillow piece 3 are slidably connected to the rear island 1.

[0041] A first support component 4 is provided between the left pillow piece 2 and the rear island 1. One end of the first support component 4 is fixedly connected to the left pillow piece 2, and the other end of the first support component 4 is slidably connected to the rear island 1. Similarly, a second support component 5 is provided between the right pillow piece 3 and the rear island 1. One end of the second support component 5 is fixedly connected to the right pillow piece 3, and the other end of the second support component 5 is slidably connected to the rear island 1.

[0042] In this embodiment, both the left headrest 100 and the right headrest 100 are slidably connected to the rear island 1. The left headrest 100 is slidably connected to the rear island 1 through a first support member, and the right headrest 100 is slidably connected to the rear island 1 through a second support member.

[0043] Specifically, the posterior island 1 includes a posterior island body 11 and a back plate 12. The back plate 12 is installed on the side of the posterior island body 11 facing the occipital bone. The back plate 12 and the posterior island body 11 are injection molded separately and then connected. Both the back plate 12 and the posterior island body 11 are crescent-shaped, and the area of ​​the back plate 12 is smaller than that of the posterior island body 11. The back plate 12 has a first sliding channel 121 and a second sliding channel 122 arranged side by side. The first sliding channel 121 and the second sliding channel 122 both extend along the length direction of the back plate 12, and both the first sliding channel 121 and the second sliding channel 122 are arc-shaped channels.

[0044] A first sliding member 6 is inserted into the first sliding channel 121. One end of the first support component 4 facing the rear island 1 is connected to the first sliding member 6. The left pillow piece 2 slides left and right along the first sliding channel 121 through the first sliding member 6.

[0045] Similarly, a second sliding member 7 is provided inside the second sliding channel 122, and one end of the second support component 5 facing the rear island 1 is connected to the second sliding member 7. The right side pillow piece 3 slides left and right along the second sliding channel 122 through the second sliding member 7.

[0046] The first slider 6 slides in an arc within the first sliding channel 121, which will cause the left pillow piece 2 to slide in an arc. The second slider 7 slides in an arc within the second sliding channel 122, which will cause the right pillow piece 3 to slide in an arc. The left pillow piece 2 and the right pillow piece 3 slide in an arc, which can change the position of the left pillow piece 2 and the right pillow piece 3 on the one hand, and change the arc angle between the left pillow piece 2 and the right pillow piece 3 on the other hand.

[0047] Furthermore, the first sliding member 6 includes a first sliding rod 61, a first baffle 62, and a second baffle 63. The first sliding rod 61 passes through the first sliding channel 121. The first baffle 62 is located at the end of the first sliding rod 61 facing the left side of the pillow piece 2 and is in contact with the back plate 12. The second baffle 63 is located at the end of the first sliding rod 61 away from the left side of the pillow piece 2 and is in contact with the back plate 12. Therefore, the first sliding member 6 has a "sandwich" structure, with the first sliding rod 61 sandwiched between the first baffle 62 and the second baffle 63. The diameters of the first baffle 62 and the second baffle 63 are both larger than the diameter of the first sliding rod 61 and the width of the first sliding channel 121. The distance between the first baffle 62 and the second baffle is exactly the thickness of the back plate 12. The side wall of the back plate 12 facing the occipital bone is defined as the first side wall, and the side wall of the back plate 12 away from the occipital bone is defined as the second side wall. The first baffle 62 contacts and abuts against the first side wall, and the second baffle 63 contacts and abuts against the second side wall. Thus, the first sliding rod 61 can be held in the first sliding channel 121 by the first baffle 62 and the second baffle 63 to slide left and right. One end of the first support assembly 4 facing the posterior island 1 is connected to the first baffle 62, and the left occipital plate 2 moves with the movement of the first baffle 62.

[0048] Similarly, the second sliding member 7 includes a second sliding rod, a third stop plate, and a fourth stop plate. The second sliding rod passes through the second sliding channel 122. The third stop plate is located at the end of the second sliding rod facing the right side of the pillow piece 3 and contacts the back plate 12. The fourth stop plate is located at the end of the second sliding rod away from the right side of the pillow piece 3 and contacts the back plate 12. Thus, the second sliding member 7 has a "sandwich" structure, with the second sliding rod sandwiched between the third and fourth stop plates. The diameters of both the third and fourth stop plates are larger than the diameter of the second sliding rod and larger than the width of the second sliding channel 122. The distance between the third and fourth stop plates is exactly the thickness of the back plate 12. The third stop plate contacts and abuts against the first side wall of the back plate 12, and the fourth stop plate contacts and abuts against the second side wall of the back plate 12. Thus, the second sliding rod is held in place in the second sliding channel 122 by the third and fourth stop plates to slide left and right. The end of the second support component 5 facing the rear island 1 is connected to the third baffle, and the right side pillow piece 3 moves with the movement of the third baffle.

[0049] Reference Figure 4 The bottom wall of the first sliding channel 121 is recessed with a plurality of first limiting grooves 1211. The plurality of first limiting grooves 1211 are arranged at intervals along the length direction of the first sliding channel 121. The first sliding rod 61 slides to the first limiting groove 1211 and is embedded in the first limiting groove 1211 to achieve locking.

[0050] The bottom wall of the second sliding channel 122 is recessed with a plurality of second limiting grooves. The plurality of second limiting grooves are arranged at intervals along the length direction of the second sliding channel 122. The second slide rod slides to the second limiting groove and is embedded in the second limiting groove to achieve locking.

[0051] It is worth mentioning that, in order to facilitate the installation of the first sliding member 6 and the second sliding member 7 into the sliding channel, the first baffle 62 is detachably connected to the first sliding rod 61, and the third baffle is detachably connected to the second sliding rod. The detachable connection can be a threaded connection. The top wall of the first sliding channel 121 is recessed with one or more first clearance grooves 1212, which are opposite to a first limiting groove 1211. The top wall of the second sliding channel 122 is recessed with one or more second clearance grooves, which are opposite to a second limiting groove. Taking the installation of the first sliding member 6 as an example, in the initial state, the first sliding rod 61 and the second stop plate 63 are integrated. During installation, firstly, the second stop plate 63 is vertically placed into the first sliding channel 121. Then, the first sliding rod 61 is moved to the position where the first limiting groove 1211 and the first clearance groove 1212 are located. Then, the first sliding rod 61 is rotated to be perpendicular to the first sliding channel 121. At this time, part of the first sliding rod 61 protrudes from the first sliding channel 121. Finally, the first stop plate 62 is tightened to the first sliding rod 61 to complete the installation. The first clearance groove 1212 and the second clearance groove provide clearance space for the rotation of the first sliding rod 61 and the second sliding rod.

[0052] In some embodiments of the present invention, the left pillow piece 2 is positioned adjustablely on the rear island 10 in the width direction, or the right pillow piece 3 is positioned adjustablely on the rear island 1 in the width direction, or both the left pillow piece 2 and the right pillow piece 3 are positioned adjustablely on the rear island 1 in the width direction.

[0053] The left pillow piece 2 and / or the right pillow piece 3 are adjusted by sliding connection between the left pillow piece 2 and / or the right pillow piece 3 and the rear island 1. The width direction of the rear island 1 is vertical, and the left pillow piece 2 and the right pillow piece 3 can slide vertically independently or simultaneously.

[0054] In the embodiment shown in the figure, in order to achieve synchronous up-and-down adjustment of the left pillow piece 2 and the right pillow piece 3, both the left pillow piece 2 and the right pillow piece 3 are mounted on the back plate 12, and the back plate 12 is slidably connected to the rear island body 11 in the width direction of the rear island body 11.

[0055] Reference Figure 5 A slider 111 is provided on the side of the rear island body 11 facing the back plate 12. The slider 111 extends along the width direction of the rear island body 11. A groove 1231 matching the slider 111 is formed on the side of the back plate 12 facing the rear island body 11. The slider 111 is inserted into the groove 1231 to realize the sliding connection between the rear island body 11 and the back plate 12.

[0056] Specifically, the slider 111 has protruding retaining edges 1112 on both sides. The outer surface of the retaining edges 1112 is flush with the outer surface of the slider 111. The thickness of the retaining edges 1112 is less than the thickness of the slider 111. The back plate 12 has a protruding protrusion 123 on the side facing the rear island body 11. The protrusion 123 has a recessed groove 1231 along the width direction of the back plate 12. The two side walls of the groove 1231 have recessed slots 1232. The recessed depth of the slots 1232 is consistent with the protruding width of the retaining edges 1112. The retaining edges 1112 are inserted into the slots 1232 to limit the slider 111 and the groove 1231.

[0057] Meanwhile, the slider 111 has several limiting protrusions 1111 protruding on the side facing the back plate 12. These limiting protrusions 1111 are arranged at intervals in the vertical direction. The bottom wall of the slide groove 1231 has several limiting recesses, the depth of which is consistent with the protrusion distance of the limiting protrusions 1111. When the back plate 12 slides to the desired position, the limiting protrusions 1111 engage with the corresponding limiting recesses to lock the back plate 12.

[0058] Figure 5 In the embodiment shown, the slider 111 has eight protrusions in four rows and two columns on the side facing the back plate 12. Correspondingly, the bottom wall of the slide groove 1231 has the same number and the same spacing of limiting recesses. During the up-and-down sliding of the back plate 12, the limiting protrusions 1111 and the limiting recesses move relative to each other. However, some of the limiting protrusions 1111 are always opposite to some of the limiting recesses. When the back plate 12 slides to the desired position, the limiting protrusions 1111 engage with the corresponding limiting recesses, thereby locking the back plate 12.

[0059] In some embodiments of the present invention, the left pillow piece 2 and / or the right pillow piece 3 are configured to be angle-adjustable.

[0060] In one embodiment, the left occipital piece 2 and the right occipital piece 3 are flexible, allowing them to deform under pressure for angle adjustment. For example, the left occipital piece 2 and the right occipital piece 3 can be made of rubber, which can elastically deform under pressure; alternatively, they can be air or water sacs, also deforming under pressure to achieve angle adjustment and conform to the user's occipital bone.

[0061] In one embodiment, a first support component 4 is provided between the left pillow piece 2 and the rear island 1. One end of the first support component 4 is connected to the left pillow piece 2, and the other end is connected to the rear island 1. The left pillow piece is angled through the first support component 4. Similarly, a second support component 5 is provided between the right pillow piece 3 and the rear island 1. One end of the second support component 5 is connected to the right pillow piece 3, and the other end is connected to the rear island 1. The right pillow piece 3 is angled through the second support component 5.

[0062] Specifically, the first support assembly 4 includes a first elastic element 41, one end of which is connected to the left pillow piece 2, and the other end of which is connected to the rear island 1. The left pillow piece 2 presses the first elastic element 41 in different directions to rotate, thereby achieving angle adjustment. The second support assembly 5 includes a second elastic element 51, one end of which is connected to the right pillow piece 3, and the other end of which is connected to the rear island 1. The right pillow piece 3 presses the second elastic element 51 in different directions to rotate, thereby achieving angle adjustment. The first elastic element 41 and the second elastic element 51 include, but are not limited to, springs, rubber washers, and rubber supports.

[0063] Specifically, the end of the first elastic member 41 facing the left pillow piece 2 is snapped into the left pillow piece 2, and the end of the first elastic member 41 facing the rear island 1 is snapped into the first sliding member 6. The end of the second elastic member 51 facing the right pillow piece 3 is snapped into the right pillow piece 3, and the end of the second elastic member 51 facing the rear island 1 is snapped into the second sliding member 7. The left pillow piece 2 is connected to the first sliding member 6 via the first elastic element 41, and the right pillow piece 3 is connected to the second elastic element 51 via the second elastic element 51. Since the first elastic element 41 and the second elastic element 51 have elastic deformation capabilities, they can be compressed or stretched in different directions. Thus, when the left pillow piece 2 contacts the user's occipital bone, the left pillow piece 2 can compress the first elastic element 41 in different directions to tilt or pitch, thereby achieving angle adjustment until the left pillow is firmly attached to the occipital bone. When the right pillow piece 3 contacts the user's occipital bone, the right pillow piece 3 can compress the second elastic element 51 in different directions to tilt or pitch, thereby achieving angle adjustment until the right pillow is firmly attached to the occipital bone.

[0064] In this embodiment, by setting the first support component 4 and the second support component 5 as elastic elements, the left occipital piece 2 and the right occipital piece 3 can not only be adjusted in position, but also in angle, which greatly improves the degree of freedom of the left occipital piece 2 and the right occipital piece 3. This allows the left occipital piece 2 and the right occipital piece 3 to dynamically conform to different shapes of the occipital bone, further improving the universality of the head pillow 100.

[0065] Furthermore, the first support component 4 also includes a first protruding ring 42, which protrudes from the side of the left pillow piece 2 facing the rear island 1. A first receiving cavity is formed within the first protruding ring 42, and a first elastic member 41 is disposed within the first receiving cavity. The end of the first protruding ring 42 facing away from the left pillow piece 2 is in contact with and connected to the rear island 1, and the left pillow piece 2 is pried with the edge of the first protruding ring 42 as a fulcrum. The free end of the first protruding ring 42 is in contact with but not fixed to the first sliding member 6. Thus, when the angle of the left pillow piece 2 is adjusted, it can be pried up with the edge of the first protruding ring 42 as a fulcrum, thereby tilting or pitching. At the same time, the first protruding ring 42 applies a pushing force to the head on the left pillow piece 2, so that the left pillow piece 2 can fit tightly against the occipital bone and give the user a pushing sensation, improving the wearing experience.

[0066] Similarly, the second support component 5 also includes a second convex ring, which protrudes from the side of the right pillow piece 3 facing the rear island 1. A second receiving cavity is formed inside the second convex ring, and a second elastic member 51 is disposed in the second receiving cavity. The end of the second convex ring opposite to the right pillow piece 3 is in contact with and connected to the rear island 1. The right pillow piece 3 is pried with the edge of the second convex ring as a fulcrum. The free end of the second convex ring is in contact with but not fixed to the second sliding member 7. Thus, when the angle of the right pillow piece 3 is adjusted, it can be pried up with the edge of the second convex ring as a fulcrum, thereby tilting or pitching. At the same time, the second convex ring applies a pushing force to the head on the right pillow piece 3, so that the right pillow piece 3 can fit tightly against the occipital bone and give the user a pushing sensation, improving the wearing experience.

[0067] The present invention also proposes a head-mounted device, which includes a display component, two straps 201, and a headrest 100. The specific structure of the headrest 100 is as described in the above embodiments. Since this head-mounted device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. One end of each strap 201 is connected to the display component, and the other end of each strap 201 is connected to the headrest 100.

[0068] 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 transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
