[0021] The utility model aims to solve the problem that the existing automobile headrest cannot be turned over at a large angle. Figure 1-4 As shown, the following technical solution is provided: a flip-over automobile headrest structure, comprising a headrest front shell 8, a back plate 2 is arranged on the rear side of the headrest front shell 8; a stop plate 11, which can be laterally moved and arranged inside the headrest front shell 8; a headrest support rod 3, a transverse connecting portion 17 at the upper end of which is located inside the headrest front shell 8, and its two ends extend downward from the back plate 2, a stop card plate 6 is sleeved on the transverse connecting portion 17, and the stop card plate 6 is provided with at least one stop card slot 15, and the lower end of the stop plate 11 is clamped with any one of the stop card slots 15; a side The push button 4 is arranged on the side of the headrest front shell 8, and its inner end is against one side of the stop plate 11, pushing the stop plate 11 to move laterally, so that the stop card plate 6 is disengaged from the stop card slot 15. An elastic member 9 is installed between the other side of the stop plate 11 and the headrest front shell 8. The headrest shell composed of the headrest front shell 8 and the back plate 2 can be adjusted to a relatively large angle around the horizontal connecting part 17. The positioning of the headrest flipping is achieved by the clamping connection between the stop plate 11 and the stop card plate 6. The stop plate 11 can be pushed to move laterally by the side push button 4, and the unlocking and positioning of the flipping can be achieved with one button.

[0022] Specifically, the headrest front shell 8 and the back plate 2 can be connected by snap-fit ​​or fasteners, the headrest support rod 3 includes two straight rods and a transverse connecting portion 17 connected to the two straight rods, the two straight rods extend from the back plate 2, and the transverse connecting portion 17 is connected to the two straight rods through a curved pipe, so that the headrest front shell 8 can be flipped at a large angle. A key frame can be installed on the outside of the side push button 4, and at least one reset spring can be installed in the key frame so that the side push button 4 can be reset.

[0023] The stop plate 11 is in the shape of a plate as a whole, and a clamping portion 13 extending toward the position of the stop clamping plate 6 is provided at its lower end. The width of the clamping portion 13 is relatively small, and only needs to be slightly larger than the thickness of the stop clamping plate 6. The position and number of the stop clamping slots 15 can be determined according to the angles at which the headrest needs to be flipped and positioned. For example, two stop clamping slots 15 are provided, corresponding to flipping 0° and 74° respectively.
