Description
Technical Field
[0001] This utility model relates to the field of automotive testing equipment technology, specifically a folding test device. Background Technology
[0002] When conducting a car seat folding test, it is often necessary to unlock the seat back.
[0003] Chinese patent CN109030056A discloses a rear seat backrest folding test device. In this device, the unlocking cylinder is connected to the unlocking handle of the seat backrest via a pull line. This structure is suitable for pull-to-unlock seats but cannot be used for press-to-unlock seats. Furthermore, the mounting structure of the folding cylinder in this device does not allow for angle adjustment.
[0004] For seat backrests with different tilt positions, unlocking often requires manually pressing the lock on the seat and releasing it after tilting to the correct position. This manual unlocking method is rather cumbersome. Chinese patent CN219284670U discloses a linkage-type seat backrest unlocking mechanism with quick unlocking capability, allowing unlocking by pressing the lock on the seat.
[0005] There is an urgent need for a seat folding test device that can accommodate both adjustable tilt cylinder angles and press-to-unlock mechanism. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0045] Please see Figures 1 to 8 As shown in Specific Embodiment 1, a car seat folding test device with a backrest unlocking mechanism includes an unlocking mechanism 1 for unlocking the seat backrest and a folding drive mechanism 2 for pushing and pulling the seat backrest. The unlocking mechanism 1 includes a clamping member 11 for clamping onto the seat headrest rod 3. A support rod 12 is mounted on the clamping member 11, and an unlocking cylinder 13 is mounted on the support rod 12. A pressure block is mounted on the telescopic rod of the unlocking cylinder 13. The folding drive mechanism 2 includes a mounting rod 21, which is connected to a drive mechanism. The first mounting piece, which is longitudinally adjustable, is connected to the crossbar 22. A rotating disk mechanism is detachably connected to the crossbar 22. The rotating disk mechanism includes a fixed disk 23 and a turntable 24 rotatably connected to the fixed disk. An arc-shaped limiting groove is provided on the turntable 24. A limiting member for moving within the arc-shaped limiting groove is installed on the fixed disk 23. A push-pull cylinder 25 for pushing and pulling the seat back is detachably connected to the turntable. A pull rope is connected to the telescopic rod of the push-pull cylinder 25. The other end of the pull rope is used to connect to the back of the seat back.
[0046] This invention facilitates unlocking of the seat by pressing the lock body through the unlocking mechanism 1. The flipping drive mechanism enables the seat back to be pushed and flipped, as well as the angle adjustment for reverse pulling. The rotating disc mechanism facilitates adaptive angle adjustment of the push-pull cylinder 25 when pulling the seat back, ensuring that the push-pull cylinder 25 applies force to the seat back and effectively reducing force distribution.
[0047] The mounting pole has a groove for longitudinal sliding connection of the first bolt, and the first mounting component is connected to the mounting pole through the first bolt.
[0048] A sliding groove is provided above the crossbar for a sliding connection to an L-shaped mounting base, which is detachably connected to the back of the fixing plate 23. A bolt passing through the L-shaped mounting base is slidably connected to the sliding groove.
[0049] The fixed disk 23 has circumferentially arranged threaded holes, and the limiting element is a bolt that is threadedly connected to the threaded holes; the turntable has two oppositely arranged arc-shaped limiting grooves, and two limiting elements are installed in the same arc-shaped limiting groove. The two limiting elements facilitate the circumferential limitation at both ends during the rotation of the turntable 24.
[0050] A reinforcing frame is mounted on the cylinder body of the push-pull cylinder 25. The reinforcing frame includes two side-by-side first support plates 27 and a second support plate 28. The first support plate 27 has a through hole for the extension rod of the push-pull cylinder 25 to extend out. The second support plate 28 is connected to the extension rod of the push-pull cylinder 25, and guide shafts 26 are fixed at both ends of the second support plate 28. The first support plate 27 has a guide sleeve for slidingly connecting the guide shafts 26. This facilitates the achievement of anti-bending strength for the extension rod.
[0051] The clamping member 11 includes a front clamping body and a rear clamping body arranged front and rear, respectively. The rear clamping body has a rearwardly extending extension. The extension has a first guide groove with a front-rear guiding direction. The extension is fixedly connected to one side of an angle iron by a bolt passing through the first guide groove. The other side of the angle iron is connected to a support rod 12 by a bolt. The support rod 12 has a matrix of mounting holes for bolts to pass through, which facilitates the adjustment of the installation position of the support rod 12.
[0052] See Figure 2 , Figure 3 as well as Figure 4 A horizontally positioned rotating shaft is fixed to the top of the support rod 12. A cylinder mounting bracket 14 is fixed to the rotating shaft, and an unlocking cylinder 13 is detachably connected to the cylinder mounting bracket 14. A first rotating shaft hole for clamping and fixing the rotating shaft is provided at the top of the support rod; a second rotating shaft hole for clamping and fixing the rotating shaft is provided on the cylinder mounting bracket; the support rod and the cylinder mounting bracket are located at opposite ends of the rotating shaft.
