[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model aims to solve the problem that the existing four-way adjustable headrest has no sleeping function and the unlocking mechanism is complicated and easy to get stuck. Figure 1-7 As shown, the following technical solution is provided: a sleeping headrest with four-way adjustment up and down and front and back, comprising a headrest body 1, a sleeping headrest portion 3 is arranged on the front side of the headrest body 1; a base 5 is arranged inside the headrest body 1; front and rear sliders 7, both ends of which are connected to the headrest body 1 and pass horizontally through the middle of the base 5; a headrest unlocking slider 10 is horizontally embedded and arranged inside the base 5, a locking block 8 passing through the middle of the headrest unlocking slider 10 is arranged in the middle of the base 5, the locking block 8 is engaged with a row of engaging teeth 16 at the bottom of the front and rear sliders 7, an elastic member 12 is arranged at the lower end of the locking block 8, and an inclined portion cooperating with the headrest unlocking slider 10 is arranged on the locking block 8 13; the support rod 2 is inserted into the base 5 from the bottom of the headrest body 1 and passes through the corresponding unlocking hole on the headrest unlocking slider 10, and the interior of the unlocking hole is provided with a locking pin 11 corresponding to the card slot 17 evenly arranged on the support rod 2; the unlocking button 4 is installed on one side of the headrest body 1, and the inner end of the unlocking button 4 is against one end of the headrest unlocking slider 10. By setting the front and rear sliders 7 passing through the base 5, the front and rear adjustment distance of the headrest can be increased, the sleeping headrest part 3 can be combined with the headrest body 1 to realize the sleeping headrest function, and the headrest unlocking slider 10 is combined with the locking block 8 and the locking pin 11 to realize one-key unlocking and four-way adjustment, which is simple to operate and will not get stuck.

[0023] Specifically, the sleeping headrest portion 3 includes a central mounting plate and side wing plates arranged on both sides of the central mounting plate. The central mounting plate and the side wing plates are connected by a damping connecting pin. The position of the side wing plates can be adjusted by rotating them around the central mounting plate to achieve the function of sleeping support. Comfort covering parts can be wrapped on the outside of the sleeping headrest portion 3 and the headrest body 1 to improve the comfort of the headrest.

[0024] When the unlocking button 4 is pressed, the headrest unlocking slider 10 will be pushed to move laterally. Since there is an inclined portion 13 between the locking block 8 and the headrest unlocking slider 10, the lateral movement of the headrest unlocking slider 10 will press the locking block 8 downward, so that the upper end of the locking block 8 is disengaged from the engaging teeth 16 at the lower part of the front and rear sliders 7, so that the base 5 can move along the front and rear sliders 7 in the headrest body 1. Since the support rod 2 is connected to the base 5, it is equivalent to realizing the front and rear movement of the headrest body 1.

[0025] When the pressing pressure on the unlocking button 4 disappears, the locking block 8 will be pushed upwards under the action of the elastic member 12, and the headrest unlocking slider 10 can be pushed sideways through the inclined portion 13, so that the headrest unlocking slider 10 and the unlocking button 4 return to their original positions. At the same time, the locking block 8 is engaged with the engaging teeth 16 to achieve the positioning engagement of the front and rear sliders 7.

[0026] At the same time, when the front and rear sliders 7 are engaged with the engaging teeth 16, the locking pin 11 is also engaged with the engaging groove 17 on the support rod 2, so that the support rod 2 cannot move vertically. When the unlocking button 4 is pressed, the headrest unlocking slider 10 moves horizontally, and the locking pin 11 is disengaged from the engaging groove 17, so that the support rod 2 can move up and down in the base 5. Therefore, when the unlocking button 4 is pressed, the headrest body 1 can be controlled to move up and down and forward and backward, which is very convenient.

[0027] In this embodiment, if Figure 4-5 As shown, a positioning pin 14 is radially passed through the upper part of the support rod 2, and a guide limit groove 15 is vertically provided on the side wall of the base 5. The positioning pin 14 is embedded in the guide limit groove 15. The cooperation between the positioning pin 14 and the guide limit groove 15 can guide the support rod 2 to move up and down to prevent deflection. The positioning pin 14 can adopt a C-type pin, which is easy to install.

[0028] In order to prevent the locking block 8 from deflecting during lifting, Figure 6-7 As shown, guide grooves are vertically arranged on both sides of the locking block 8, and a guide protrusion 9 embedded in the guide groove is arranged in the middle of the base 5 to guide the locking block 8 to move up and down.

[0029] In order to guide the support rod 2, as Figure 3 and 7 As shown, the interior of the base 5 is provided with a guide sleeve 6 which is sleeved on the outside of the support rod 2, and the guide sleeve 6 can guide the up and down sliding of the support rod 2. The guide sleeve 6 can be set to a semi-open structure, the lower part of which is clamped with the base 5, and the upper part extends upward and is close to the support rod 2.

[0030] like Figure 7As shown, the inclined portion 13 is arranged on both sides of the isosceles trapezoidal steps on both sides of the locking block 8, which can smoothly press the locking block 8 downward to achieve unlocking, and can also play a guiding role when the locking block 8 is reset. In this way, the unlocking button 4 can be installed on any side of the headrest body 1, or the unlocking buttons 4 can be arranged on both sides of the headrest body 1, which is more convenient.

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
