Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted headrests, in particular to a sleeping headrest. Background Art

[0002] As a sleep aid designed specifically for vehicle passengers, a car headrest can enhance passenger comfort during long drives or road trips. It conforms to the curve of the neck, providing additional support, effectively alleviating neck and head fatigue and enhancing ride comfort. Furthermore, for passengers needing to nap or on long rides, a suitable headrest can provide a more comfortable sleeping environment. It can reduce head shaking and maintain stability, helping passengers fall asleep faster and improving sleep quality.

[0003] However, most of the existing car sleeping headrests on the market are soft cushions arranged on the seat headrest, which can only fit the neck curve and provide support for the passengers in the front and back directions, but cannot provide support in the left and right directions. When the passengers sleep, their heads will fall to one side, which can easily cause damage to the neck and is not conducive to the passengers' sleep quality and neck health. Utility Model Content

The front sides of the two bite blocks 3 are respectively formed with T-shaped structures, and the T-shaped structures are respectively slidably arranged in the corresponding slide grooves 10. The opposite sides of the two bite blocks 3 are formed with a mouthpiece 4 that can be engaged with the two support rods of the car seat headrest, and a protective pad is fixed on the inner wall of the mouthpiece 4 to avoid damaging the support rod. The sliding positioning structure is specifically as shown Figure 3 、 4 As shown, it includes a pressing block 5, a spring 8, a tooth block 7 and a rack 9; the bite block 3 is a hollow shell structure, the pressing block 5 is slidably arranged inside the bite block 3, and is connected to the inner bottom surface of the bite block 3 through a spring 8 (as shown in FIG. Figure 4 As shown, a positioning groove is formed in the bite block 3, and ribs are formed on the inner wall of the positioning groove. The bite block 3 is sleeved and fitted in the positioning groove, and rib grooves are formed on the outer wall corresponding to the ribs). A press key 6 is formed in the middle of the top surface of the pressing block 5, and is arranged through the key hole reserved on the top wall of the bite block 3 (the press key 6 is a columnar structure and cooperates with the key hole). A tooth block 7 is also fixed on the top surface of the pressing block 5 (the tooth block 7 is formed on the front side of the pressing block 5 at the position corresponding to the rack 9), and after the tooth block 7 passes through the top wall of the bite block 3, it engages with the rack 9 fixed on the inner top surface of the slide groove 10, and after the tooth block 7 and the rack 9 are engaged, the bite block 3 cannot slide inward. After the press key 6 is pressed and sunk, the tooth block 7 and the rack 9 are separated, and the bite block 3 can slide inward.

[0029] The side headrest 1 is shaped like Figure 6 As shown, a pair of left and right mirror images are provided, and are rotatably arranged on the left and right sides of the base 2 through a rotating positioning structure. A support plate is provided inside, and a cushion is wrapped outside, and a mounting sleeve 19 is fixed at the tail end.

[0030] Rotation positioning structure such as Figure 5 、 6As shown, it includes an inner cylinder sleeve 12, a C-shaped sleeve 13, a lock tongue 14, a spring 16, an outer cylinder sleeve 17, a limit bolt 18 and a limit rotary cover 11; an inner cylinder sleeve 12 and a C-shaped sleeve 13 are formed on the side of the base 2, the outer cylinder sleeve 17 is divided into a positioning section and a rotating section, the rotating section is movably sleeved on the inner cylinder sleeve 12, and a plurality of positioning card grooves 21 are evenly arranged on the inner wall of the positioning section along the circumferential direction. The opening of the C-shaped sleeve 13 is arranged upward and arranged on the outside of the inner cylinder sleeve 12, and the lock tongue 14 is a structure with a card protrusion 20 formed on the outer wall of the arc plate. The arc plate is movably arranged on the inner side of the C-shaped sleeve 13, and the two ends are respectively connected to the step surface 15 formed on the inner bottom of the C-shaped sleeve 13 through the spring 16, and the card protrusion 20 penetrates It passes through the opening of the C-shaped sleeve 13 and protrudes to the outside of the C-shaped sleeve 13, and the end of the clamping protrusion 20 is formed with a rounded structure that cooperates with the positioning slot 21, so that when the rotary positioning structure rotates, the lock tongue 14 is pressed down by the positioning slot 21, and the limiting bolt 18 is threadedly sleeved in the inner sleeve 12, and the outer sleeve 17 is limited on the inner sleeve 12. The mounting sleeve 19 at the tail end of the side headrest 1 is sleeved and fixed on the positioning segment of the outer sleeve 17 (a spline is formed on the outer wall of the positioning segment), and a thread is formed on the outer wall of the rotating segment of the outer sleeve 17. The limiting rotary cover 11 is a cap structure, and after being threaded with the rotating segment, the inner side wall conflicts with the mounting sleeve 19 and limits the mounting sleeve 19 to the outer sleeve 17.

[0031] In the specific implementation of this embodiment:

[0032] During installation, place the base 2 on the car seat (before the two support rods below the headrest of the car seat), and slide the two bite blocks 3 to both sides so that the headrest support rods on both sides are respectively engaged in the two bite mouths 4. Then the sleeping headrest is fixed on the car seat, and the side headrests 1 on both sides are flipped upwards to both sides of the car seat headrest to prevent affecting driving.

[0033] When sleeping, the side headrests 1 on both sides are flipped down so that the side headrests 1 are in contact with the car seat back and arranged on both sides of the passenger's head. The passenger lies on the car seat and sleeps on one of the side headrests 1.

[0034] When disassembling, press the push button 6, the tooth block 7 and the rack 9 are separated, so that the bite block 3 can slide inward, thereby separating from the headrest support rods on both sides, and finally the sleeping headrest is removed and stored.

[0035] As a different embodiment, a concealable hook may be provided on the rear side of the mouthpiece 4. Figure 4As shown, the mouthpiece 4 is a hollow structure consisting of a pair of upper and lower mouthpiece shells, with an L-shaped hook plate 22 disposed within. During operation, pressing the hook plate 22 once pushes it in and hides it within the mouthpiece 4. Pressing it again ejects it (the mechanism of pressing the hook plate 22 to hide or pop it out is common knowledge and prior art), allowing it to be used to hang items such as bags.

[0036] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
