Technical Field

[0001] The utility model relates to the field of headrests, in particular to a headrest shell. Background Art

[0002] A car headrest is a driving comfort configuration and safety protection product. Common headrest fabrics on the market are mostly high-grade silk, velvet or pure cotton, filled with fluffy cotton. With the existence of a car headrest, it can effectively cushion the huge instantaneous impact force when an accident occurs, thereby protecting the fragile cervical vertebrae and reducing the chance of neck injury. At the same time, a shell will be set inside to provide support.

[0003] In the process of realizing the present utility model, the inventors found that there are at least the following problems in this technology: since the headrest and the seat need to be connected through a connecting rod, multiple bolts are used during the installation of the headrest and the connecting rod, which makes the installation inconvenient. Therefore, a headrest shell is now proposed. Utility Model Content

[0004] In order to improve the problem of inconvenient installation of a headrest and a connecting rod, the utility model provides a headrest shell.

[0005] The utility model provides a headrest shell, which adopts the following technical solution:

[0006] A headrest shell, comprising a headrest rear shell, a headrest front shell is installed above the headrest rear shell, an upper cover is fixed to one side of the outer wall of the headrest front shell, a lower cover is connected to the lower side of the upper cover, and a connecting mechanism is arranged on one side of the lower cover;

[0007] The connecting mechanism includes a connecting rod, which passes through the interior of the lower cover, and a limiting block is fixed at one end of the connecting rod that passes through the lower cover. A ring is provided on the outer wall of the end of the connecting rod that passes through the lower cover, and a connecting ring is fixed on the top of the ring. A connecting plate is fixed on the outer wall of the end of the connecting ring away from the ring, and a limiting hole is provided on the connecting plate corresponding to the position of the limiting block. A pressing plate is slidably connected inside the upper cover and the lower cover.

[0008] By adopting the above technical solution, the upper cover and the lower cover are quickly fixed by connecting the headrest rear shell and the headrest front shell, so that the connecting rod can be installed, avoiding the inconvenience and trouble of installation.

[0009] Optionally, the outer dimensions of the limiting hole are consistent with those of the limiting block, and the limiting block forms a snap-fit ​​structure with the connecting plate through the limiting hole.

[0010] By adopting the above technical solution, the limiting block is limited by the limiting hole, so as to prevent the connecting rod from rotating, thereby affecting the connection with the seat.

[0011] Optionally, a telescopic spring is sleeved on the outside of the collar, and a damping spring is embedded at a position corresponding to the limiting hole at the bottom end of the pressing plate.

[0012] By adopting the above technical solution, through the cooperation of the telescopic spring and the damping spring, the headrest has a certain elasticity and shock absorption when it is subjected to pressure, thereby improving the comfort during use.

[0013] Optionally, a limiting mechanism is provided inside the pressing plate, and the limiting mechanism includes a fixing rod, the fixing rod penetrates into the middle position of the pressing plate, and an insertion rod penetrates out of the fixing rod, and an extension rod is fixed at the position where the insertion rod penetrates out of the fixing rod.

[0014] By adopting the above technical solution, the fixing rod and the extension rod allow the pressing plate to slide stably when subjected to force, thereby avoiding deviation and affecting the comfort of the headrest.

[0015] Optionally, the penetration rod penetrates into the interior of the fixed rod, and a sliding structure is formed between the penetration rod and the fixed rod.

[0016] By adopting the above technical solution, the fixing rod and the extension rod are prevented from being misplaced or offset by the insertion rod, thereby preventing the upper cover and the lower cover from being accurately docked.

[0017] Optionally, a shock absorbing mechanism is provided on one side of the pressing plate, and the shock absorbing mechanism includes a fixed base, the fixed base is fixed to the top of the pressing plate, and a penetration block is connected above the fixed base, a sleeve is provided on the outside of the penetration block, and a shock absorbing spring is fixed to the top of the penetration block.

[0018] By adopting the above technical solution, the penetration block slides in the sleeve tube through the shock-absorbing spring, thereby further improving the shock-absorbing effect of the headrest and improving the comfort during use.

[0019] Optionally, the shock absorbing mechanism further comprises a sealing gasket, which is connected to one side of the shock absorbing spring at the top end of the penetration block, and an air outlet is provided above the outer wall of the sleeve tube.

[0020] By adopting the above technical solution, the sleeve tube cooperates with the sliding of the penetration block through the sealing gasket to form a piston movement, and the air pressure is slowly reduced through the air outlet, thereby avoiding direct damage to the shock-absorbing spring and causing head injury.

[0021] Optionally, the penetration block is bonded to the sealing gasket, and a sliding structure is formed between the penetration block and the sleeve tube.

[0022] By adopting the above technical solution, the sealing performance of the penetration block is improved by the sealing pad, so that the gas loss is prevented from being too fast, and the air pressure can be formed to prevent the discomfort to the head and neck caused by too fast contraction.

[0023] In summary, the utility model has the following beneficial effects:

[0024] 1. The utility model firstly allows the connecting rod to pass through the collar and the connecting ring, and allows the limit block to pass through the limit hole of the connecting plate to limit and prevent rotation. At the same time, the collar and the connecting ring are clamped between the upper cover and the lower cover. The collar and the connecting ring are fixed by fixing the headrest rear shell and the headrest front shell, so that the upper cover and the lower cover are fixed to fix the collar and the connecting ring, so that the connecting rod is quickly fixed to avoid the trouble of installation in the form of bolts or welding. The damping spring is driven by the pressing plate to elastically press the limit block to prevent it from detaching. At the same time, it cooperates with the telescopic spring to achieve a shock-absorbing effect when subjected to force.

[0025] 2. The utility model avoids dislocation or offset by making the fixing rod and the extension rod interfere with each other and limiting the position of the penetration rod, so that the upper cover and the lower cover can be stably docked to avoid dislocation due to force. At the same time, when the headrest is under pressure, the pressing plate slides through the fixing rod and the extension rod when the force is applied, avoiding offset, causing discomfort to the head and reducing the comfort of the headrest.

[0026] 3. The utility model further improves the shock-absorbing effect when the pressing plate slides under force, and the shock-absorbing spring fixed by the penetration block on the top of the fixed base slides along the sleeve tube, while avoiding the bending of the shock-absorbing spring under force. The sealing gasket bonded by the penetration block forms a piston motion with the sleeve tube, and the compressed gas is slowly discharged through the air outlet. The slow loss of air pressure generates a certain air pressure resistance to avoid direct elastic contraction when force is applied, which can provide a certain protective measure against head injuries.
