Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a clamping structure of an automobile seat headrest. Background Art

[0002] An automobile seat headrest is a driving comfort configuration item and a safety protection item. In the event of a traffic accident, the huge impact force generated by the collision is all squeezed on the vulnerable neck, making it very likely that the spinal cord of the driver and passengers will be damaged. In severe cases, it may even cause problems in the nervous system leading to paralysis or even endanger life. With the existence of the automobile headrest, it can effectively buffer the huge instantaneous impact force during an accident, thereby protecting the vulnerable cervical vertebrae and reducing the probability of neck injury. An automobile seat headrest usually includes a headrest foam, a headrest plastic part, and a headrest rod. The headrest plastic part serves as the skeleton of the headrest to support the headrest foam, and the headrest rod is usually installed on the back of the headrest rod. The main problems existing in the existing headrest structure are: the assembly structure of the headrest plastic part and the headrest rod is complex, it is difficult to achieve quick disassembly and assembly, and the operation is inconvenient; especially for the existing integral headrest, since the headrest rod needs to be pre-welded on the backrest skeleton, the assembly of the headrest plastic part and the headrest rod is even more troublesome. Content of the Utility Model

[0003] Aiming at the problems existing in the above-mentioned prior art, the utility model aims to provide a clamping structure of an automobile seat headrest to solve the problem that it is difficult to quickly assemble the existing headrest plastic part and the headrest rod, and it is applicable to integral headrests.

[0004] To achieve the above object, the utility model provides a clamping structure of an automobile seat headrest, including a headrest plastic part and a U-shaped headrest rod. The U-shaped headrest rod includes a horizontal section and two legs. A connecting sheet metal is provided between the two legs of the U-shaped headrest rod. The upper end of the connecting sheet metal is first bent forward to form a first bending section, and then bent upward to form a second bending section. Buckle holes are respectively provided at both ends of the first bending section, and a square limiting hole is provided between the two buckle holes. Half of the square limiting hole is located on the first bending section, and the other half is located on the second bending section; a clamping seat is provided at the upper part of the back surface of the headrest plastic part. A U-shaped groove with a downward opening is provided on the clamping seat corresponding to the horizontal section of the U-shaped headrest rod. A limiting seat is provided below the clamping seat corresponding to the square limiting hole. Limiting columns are provided on both sides of the limiting seat. On one side of the upper walls of the two limiting columns, buckles are respectively provided corresponding to the two buckle holes; when the headrest plastic part is clamped on the horizontal section through the U-shaped groove and is flipped backward, the limiting seat can be clamped into the square limiting hole to achieve left and right limitation, and the two buckles can be clamped into the corresponding side buckle holes to achieve front-back and up-down limitation.

[0005] In the above solution: when the buckle is clamped into the corresponding side buckle hole, the rear end surface of the limiting column can just contact the front end of the connecting sheet metal to achieve rear limitation, further ensuring the connection reliability between the headrest plastic part and the U-shaped headrest rod.

[0006] In the above solution: when the buckle is snapped into the corresponding side buckle hole, the upper end surface of the limit seat can just contact the top end of the square limit hole to achieve upper limit, further ensuring the connection reliability between the headrest plastic part and the U-shaped headrest rod.

[0007] In the above solution: the two buckles are symmetrically arranged left and right, and the buckle is an anti-disengagement buckle, with a simple structure and convenient design. The anti-disengagement buckle can prevent the headrest plastic part from disengaging.

[0008] In the above solution: the headrest of the vehicle seat and the backrest are of an integral fixed structure. The backrest includes a backrest skeleton and backrest foam. The two feet of the U-shaped headrest rod are welded to the backrest skeleton, and the backrest foam extends to the top end of the U-shaped headrest rod. A notch for the upper end of the U-shaped headrest rod to pass through is provided on the front end surface of the upper part of the backrest foam. The integral headrest is beneficial to ensuring the aesthetic appearance of the overall shape of the seat.

[0009] The beneficial effects of the present utility model are as follows: 1. The headrest plastic part is clamped on the horizontal section through the U-shaped groove and then flipped backward, so that the limit seat is snapped into the square limit hole to achieve left and right limit, and at the same time, the buckle is snapped into the corresponding side buckle hole to achieve front-back and up-down limit. Coupled with the front-back limit and up-limit achieved by the clamping connection between the horizontal section and the U-shaped groove, the reliable connection between the headrest plastic part and the U-shaped headrest rod is effectively realized, and the disassembly and assembly are convenient, greatly improving the assembly efficiency of the U-shaped headrest rod and the headrest plastic part; 2. When assembling, the headrest rod remains stationary and the headrest plastic part moves, so it is also applicable to an integral headrest in which the headrest rod is pre-welded to the backrest skeleton.
