All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes:

[0030] Rotating rod 1, there are several rotating rods 1 and they are in pairs. The two rotating rods 1 in the same group are screwed to the side wall of the headrest 2 by bearings. The rotating rod 1 plays an adjustment role.

[0031] The rotating frame 3 consists of several rotating frames. The rear ends of the rotating frames 3 are screwed onto the rotating rod 1 using bearings. The front ends of the rotating frames 3 are screwed onto the fixing ring 4 using rotating rods. The fixing ring 4 has a fixing groove 5 on its side wall. The position of the fixing ring 4 can be adjusted by rotating the rotating frame 3.

[0032] The air cylinder 6 is a hollow cylindrical structure, and there are several air cylinders 6. The air cylinders 6 are movably inserted into the fixing ring 4 by fixing components 7. The front end of the air cylinder 6 is movably inserted into the piston rod 8. The piston rod 8 compresses the gas in the air cylinder 6 to counteract the impact force. The outer wall of each air cylinder 6 is fitted with a friction pad 20, and the friction pad 20 is set to abut against the fixing component to increase the friction between the air cylinder 6 and the fixing ring 4 and prevent the air cylinder 6 from moving within the fixing ring 4. The front and rear ends of each air cylinder 6 are respectively provided with a limiting ring 24, and the limiting ring 24 is set to abut against the fixing ring 4 to restrict the position of the air cylinder 6 and prevent the air cylinder 6 from detaching from the fixing ring 4.

[0033] The protective plate 9 is located on the front side of the headrest 2. The protective plate 9 is equipped with a protective air cushion 10. Two fixing plates 25 are fixedly installed on the left and right sides of the protective plate 9 respectively. The front end of the piston rod 8 is connected to the fixing plate 25. By adjusting the position of the protective plate 9, the protective air cushion 10 is made to contact the head, which is convenient for protecting the head. The left and right sides of the protective plate 9 are respectively fixed with baffles 21. The baffles 21 are equipped with buffer pads 22. The baffles 21 play a limiting role, restricting the head on the protective plate 9. The front side of the protective plate 9 is provided with a positioning groove 23. The protective air cushion 10 is placed in the positioning groove 23, which is convenient for protecting the head in the positioning groove 23.

[0034] Adjusting sleeve 11, there are two adjusting sleeves 11, which are movably sleeved on the left and right rotating frames 3 respectively. The end of the connecting rod 26 is screwed to the two adjusting sleeves 11 by a rotating rod. The adjusting sleeves 11 play the role of controlling the rotation of the rotating frame 3.

[0035] The adjusting screw 12 is screwed to the backrest 27 by means of a bearing at its bottom end, and is threaded onto the connecting rod 26. The adjusting screw 12 controls the height of the connecting rod 26, thereby adjusting the rotation angle of the rotating frame 3.

[0036] Fixed component 7 includes:

[0037] Positioning block 13, there are several positioning blocks 13, and the several positioning blocks 13 are respectively fixedly arranged on the fixing ring 4, and the positioning blocks 13 are located at the fixing groove 5. The positioning blocks 13 play a positioning role.

[0038] The fixing rod 14 is a plurality of fixing rods, which are respectively fixedly installed on the side wall of the air cylinder 6, and the fixing rod 14 is movably locked in the fixing groove 5. The fixing rod 14 is provided with a locking groove 15. The fixing rod 14 plays a guiding role. By locking the fixing rod 14 in the fixing groove 5, the air cylinder 6 is prevented from rotating in the fixing ring 4.

[0039] Movable block 16, there are several movable blocks 16, which are slidably disposed in the groove of positioning block 13. A slot 17 is provided on the side of the movable block 16. The retaining plate 18 is screwed into the slot 17 by a spring-loaded rotating rod. The retaining plate 18 and the retaining groove 15 are engaged and abutted. The position of the retaining plate 18 is adjusted by the movable block 16 so that the retaining plate 18 abuts against the retaining groove 15.

[0040] Positioning screws 19, there are several positioning screws 19, each of which is screwed onto the positioning block 13, and the end of the positioning screw 19 is screwed onto the corresponding movable block 16 by means of a bearing. The positioning screws 19 control the position of the movable block 16.

[0041] When using this utility model, the operator first rotates the adjusting screw 12 according to the position of the driver's head. The adjusting screw 12 drives the connecting rod 26 to move up and down. The connecting rod 26 drives the adjusting sleeve 11 to move. The adjusting sleeve 11 drives the corresponding rotating frame 3 to rotate. The rotating frame 3 drives the fixing ring 4 to move. The fixing ring 4 drives the air cylinder 6 to move, thereby driving the protective plate 9 to move up and down until the protective plate 9 is moved to the appropriate position. Then, the operator moves the air cylinder 6 by moving the protective plate 9. The air cylinder 6 drives the fixing rod 14 to move within the fixing ring 4, adjusting the front and rear position of the protective plate 9 until the protective air cushion 10 contacts the head. The operator then rotates the positioning screw 19. The positioning screw 19 drives the movable block 16 to move within the groove of the positioning block 13. The movable block 16 drives the locking plate 18 to move, so that the locking plate 18 is locked in the locking groove 15, thereby restricting the position of the air cylinder 6.

[0042] When the driver's head hits the protective airbag 10, the force is transmitted to the piston rod 8 through the protective plate 9, causing the piston rod 8 to move and compress the gas in the air cylinder 6, thereby offsetting the impact force and protecting the head to a certain extent.

[0043] Compared with the prior art, the beneficial effects of this utility model are:

[0044] By adjusting the screw 12 and connecting rod 26, the position of the protective plate 9 is adjusted. Then, by adjusting the air cylinder 6 and piston rod 8, the stress between the head and the protective plate 9 is offset, which helps to protect the driver's head.

[0045] The fixed component 7 is set up, and the position of the movable block 16 is controlled by the positioning screw 19 so that the card plate 18 abuts against the card slot 15, which facilitates the positioning of the air cylinder 6, thereby controlling the position of the protective plate 9 so that the head contacts the protective air cushion 10.

[0046] Friction pad 20 is provided to increase the friction between air cylinder 6 and fixed ring 4 and prevent air cylinder 6 from shifting.

[0047] The baffle 21 is set to restrict the head position to a certain extent, so as to make it easier to keep the head on the protective plate 9.

[0048] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
