[0002] The flip-up rear seats in commercial vehicles are designed to improve the space utilization and versatility of the vehicle. This design allows the seats to be flipped or folded up when the rear seats are not needed to make more space for cargo or provide a flatter loading surface.

[0003] The Chinese utility model patent with authorization announcement number CN202827201U discloses a flip and folding seat, including a backrest frame, the bottom end of the backrest frame is rotatably connected to the seat cushion frame, backrest fixing plates are arranged on both sides of the bottom end of the backrest frame, seat cushion fixing plates corresponding to the backrest fixing plates are arranged on both sides of the seat cushion frame, the backrest fixing plate and the seat cushion fixing plate are hinged by the backrest rotation axis pin, a locking pin bracket is arranged on the back side of the seat cushion frame, the backrest frame is provided with a backrest locking pin, the backrest locking pin and the seat cushion locking pin form a lock, and a skeleton support is fixedly provided at the bottom end of the seat cushion frame. When flipping is required, the lock is unlocked, and the backrest frame is pushed to rotate and fold forward around the rotation axis pin until the backrest frame and the seat cushion frame are fitted together, and then the entire chair is flipped so that the front end of the seat cushion frame contacts the surface of the vehicle floor, releasing the space occupied under the seat cushion frame.

[0004] However, the existing technology still has the following defects: after the backrest frame is rotated and fits with the seat cushion frame, the skeleton support fixed under the seat cushion frame still occupies the space in the vehicle. At the same time, the backrest frame and the seat cushion frame are not fixed after being folded. In response to the above technical problems, the following improvements are proposed. Utility Model Content

[0005] The utility model aims to provide a one-piece flip seat, so that the legs can be folded after the seat cushion assembly is flipped, thereby further expanding the accommodation space in the vehicle.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a one-piece flip seat, characterized in that: it includes a backrest assembly, shoulder bolts are protruding on both sides of the bottom end of the backrest assembly; a cushion assembly, the cushion assembly is rotatably connected to the backrest assembly; the bottom end of the cushion assembly is rotatably connected to the support assembly; the backrest assembly is fixedly provided with a pull strap for fixing the cushion assembly when it rotates to the backrest assembly, and the cushion assembly is provided with a pull rod corresponding to the pull strap, and the pull strap cooperates with the pull rod to fix the cushion assembly.

[0007] By adopting the above technical solution, the seat cushion assembly is rotatably connected to the backrest assembly, and the seat cushion assembly is pushed when it needs to be rotated until the seat cushion assembly leans against the backrest assembly. The support assembly is rotatably connected at the bottom end of the seat cushion assembly, and when the seat cushion assembly rotates upward and leans against the backrest assembly, the support assembly is pushed to rotate toward the seat cushion assembly until it leans against the seat cushion assembly. Finally, the seat cushion assembly is fixed by the cooperation of the pull strap and the pull rod. Compared with the existing technology, after the seat cushion assembly and the backrest assembly are folded, the support assembly does not occupy the space inside the vehicle, providing a larger accommodation space inside the vehicle, which has the effect of expanding the accommodation space inside the vehicle.

[0008] Furthermore, the backrest assembly includes a backrest bracket fixed to the vehicle body and a backrest body arranged on the backrest bracket, the backrest bracket is connected with a shoulder bolt, and a threaded hole adapted to the shoulder bolt is opened at the bottom end of the backrest bracket.

[0009] By adopting the above technical solution, by setting the shoulder bolt as a shoulder bolt, the diameter of the threaded hole is adapted to the screw rod of the shoulder bolt, and the shaft diameter of the shoulder bolt is larger than the diameter of the screw rod, a gap is formed between the shoulder bolt and the backrest bracket for the plate body to rotate, thereby achieving the purpose of rotating the seat cushion bracket at the shoulder bolt.

[0010] Furthermore, a plate body is protrudingly provided on both sides of the seat cushion assembly close to the backrest assembly. The plate body is provided with a connecting hole for the shoulder bolt to pass through, and a ring washer is provided between the shoulder bolt and the plate body.

[0011] By adopting the above technical solution, by setting a ring gasket, the plate body rotates at the shoulder bolt through the connecting hole, and there is friction between the two. Long-term rotation will cause more serious wear between the plate body and the shoulder bolt. Therefore, the use of a ring gasket can reduce the friction between the plate body and the shoulder bolt, and can achieve the purpose of reducing the wear of the shoulder bolt and the plate body.

[0012] Furthermore, the seat cushion assembly includes a seat cushion bracket rotatably connected to the backrest bracket and a seat cushion body arranged above the seat cushion bracket, the plate body is fixedly arranged on the seat cushion bracket, the pull rod is fixedly arranged below the seat cushion bracket, and there is a gap between the pull rod and the seat cushion bracket for the pull strap to pass through.

[0013] By adopting the above technical solution, a gap is set between the pull rod and the seat cushion bracket. When the seat cushion assembly is rotated, the seat cushion bracket is located on the side away from the backrest assembly. At this time, the pull strap passes through and is fixed in the gap between the pull rod and the seat cushion bracket, thereby fixing the seat cushion assembly, which can achieve the purpose of conveniently intercepting and fixing the pull rod with the pull strap.

[0014] Furthermore, the drawstring fixing method is set to be a Velcro type.

[0015] By adopting the above technical solution, by setting the fixing method of the drawstring to Velcro type, when the seat cushion assembly is rotated upward and leans against the backrest assembly, the seat cushion bracket drives the pull rod to move. At this time, the drawstring is passed through the gap between the pull rod and the seat cushion bracket and pasted around the pull rod, so that the drawstring and the pull rod can cooperate to fix the flipped seat cushion assembly.

[0016] Furthermore, the support assembly is detachably connected to screws for fixing the seat cushion bracket to the vehicle body.

[0017] By adopting the above technical solution and setting screws, when the seat cushion bracket is in a non-rotating state, the support assembly is fixed to the vehicle body by the screws, which can reduce the displacement of the seat cushion assembly caused by the sliding of the vehicle body during operation.

[0018] Furthermore, the support assembly includes a support leg rotatably connected to the seat cushion bracket and a cross bar connected to the support leg, and a screw is used to pass through the cross bar and be threadedly connected to the vehicle body.

[0019] By adopting the above technical solution, since the support legs are rotatably connected to the seat cushion bracket, the support legs will shake on the seat cushion bracket due to the shaking of the vehicle body during operation, which can effectively prevent passenger injuries and equipment damage.

[0020] A rotating seat for rotating the support leg is provided at the bottom end of the seat cushion bracket. An opening is provided on one side of the rotating seat. A positioning rod is inserted into the opening side of the rotating seat. The support leg is provided with a positioning hole for the positioning rod to pass through. When the support leg is rotated to be parallel to the seat cushion assembly, the positioning rod can pass through the side wall of the rotating seat and the positioning hole at the same time.

[0021] By adopting the above technical solution and setting a positioning rod and a positioning hole, when the seat cushion assembly is rotated to be parallel to the backrest assembly, it is necessary to manually rotate the support leg to a position parallel to the seat cushion bracket to achieve the purpose of saving space in the vehicle. At this time, the rotated support leg needs to be positioned to prevent the support leg from resetting due to shaking of the vehicle body during movement. Therefore, the positioning rod is passed through the seat cushion bracket and the support leg, which can achieve the purpose of positioning the support leg. When the support leg is not rotated, the positioning rod is inserted into the side of the rotating seat opening. At this time, the seat cushion assembly and the support leg are not flipped over, and the support leg supports the seat cushion assembly. Therefore, during the operation of the vehicle body, the support leg has a tendency to swing at the rotating seat, and at this time the support leg has a tendency to rotate toward the direction of the rotating seat opening, and the positioning rod blocks the swinging tendency of the support leg, thereby reducing the pressure of the screw when positioning the support leg assembly, protecting the screw and the vehicle body, and achieving the purpose of protecting the equipment from damage.

[0022] The beneficial effect is that the positioning rod can not only position the folded supporting legs, but also be plugged into the rotating seat before flipping and limit the swing of the supporting legs, which has the effect of reducing the pressure between the screws and the vehicle body.

[0023] Furthermore, a connecting belt is provided between the seat cushion bracket and the positioning rod.

[0024] By adopting the above technical solution and providing a connecting belt, the two ends of which are respectively connected to the positioning rod and the cushion bracket, the positioning rod can be effectively prevented from being lost. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The embodiment is basically as shown in the attached Figure 1-5 As shown:

[0033] One-piece flip seat, such as Figure 1 、 Figure 2 、 Figure 3As shown, it includes a backrest assembly 1, a seat cushion assembly 2 and a support assembly 4, wherein the backrest assembly 1 includes a backrest bracket 13 and a backrest body 14, the backrest bracket 13 is fixedly arranged on the vehicle body, and the backrest body 14 is arranged on the side of the backrest bracket 13 away from the vehicle body; the seat cushion assembly 2 includes a cushion body 24 and a cushion bracket 23, the cushion bracket 23 is rotatably connected to the bottom end of the backrest bracket 13, and the cushion body 24 is arranged on the upper surface of the cushion bracket 23, and the support assembly 4 includes a support leg 41 and a cross bar 42, the cross bar 42 is fixedly connected to the support leg 41, and the cross bar 42 is threadedly connected with a screw 421, and the screw 421 can pass through the cross bar 42 and be connected to the vehicle body.

[0034] The two sides of the bottom end of the backrest bracket 13 are respectively connected with shoulder bolts 11, and the shoulder bolts 11 protrude from both sides of the bottom end of the backrest bracket 13. The two ends of the seat cushion bracket 23 close to the backrest bracket 13 are respectively provided with plates 21, and the plates 21 protrude from both sides of the seat cushion bracket 23. The plate 21 is provided with a connecting hole 211 for the shoulder bolt 11 to pass through, wherein the shoulder bolt 11 is provided as a shoulder bolt 11, and the shaft diameter of the shoulder bolt 11 is larger than the rod diameter of the screw. Threaded holes 131 for the shoulder bolt 11 to connect and pass through are provided on both sides of the bottom end of the backrest bracket 13, wherein the aperture of the threaded hole 131 is larger than the diameter of the shoulder The diameters of the screw portion of the bolt 11 are adapted, the shaft diameter of the shoulder bolt 11 is larger than the aperture of the threaded hole 131, and an annular washer 3 is provided between the plate body 21 and the shoulder bolt 11. Since the shoulder bolt 11 and the plate body 21 generate relative rotation through the connecting hole 211, when the seat cushion assembly 2 needs to be flipped over, the seat cushion is manually rotated, and the seat cushion assembly 2 drives the plate body 21 to rotate at the shoulder bolt 11 with the shoulder bolt 11 as the center. Under long-term rotation, the shoulder bolt 11 and the plate body 21 are prone to wear. Therefore, the design of the annular washer 3 can effectively reduce the wear between the shoulder bolt 11 and the plate body 21, which helps to protect the equipment.

[0035] Further, such as Figure 1 、 Figure 4 As shown, a drawstring 12 is fixedly provided on the backrest assembly 1, and a pull rod 22 is fixedly provided at the bottom end of the seat cushion bracket 23.
