[0024] The utility model provides a flip reset assembly and a seat bag recovery structure. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0025] See also Figure 2-Figure 4 The utility model provides a flip reset assembly, including a round seat 1, a fixed shaft 2, a bracket 3, a spring 4 and a limit rod 5; the round seat 1 is used to be fixedly connected to the support arm 10, and the fixed shaft 2 extends laterally and is fixedly connected to the round seat 1; the bracket 3 can rotate around the circumference of the fixed shaft 2, and the outer peripheral wall of the fixed shaft 2 is also fixedly connected to one end of the spring 4, and the other end of the spring 4 abuts against the inner cavity of the bracket 3; an arc-shaped limit groove 13 is opened on the round seat 1, the bracket 3 is fixedly connected to the limit rod 5, and the outer end of the limit rod 5 is located in the arc-shaped limit groove 13; the bracket 3 is used to be fixedly connected to the seat bag 20, and the fixed shaft 2, the bracket 3, the spring 4, and the limit rod 5 are all located inside the seat bag 20.

[0026] See also Figure 1 and Figure 2In actual application, the support arm 10 is fixedly connected to the supporting structure of the seat, and the round seat 1 is fixedly connected to the inner wall of the support arm 10 .

[0027] See also Figure 4 When the seat bag 20 fixed to the bracket 3 needs to be flipped down for people to sit on, the seat bag 20 drives the bracket 3 to flip downward around the fixed axis 2, so that the spring 4 is compressed. During the flipping process, the bracket 3 drives the limit rod 5 fixed to it to move synchronously, so that the end of the limit rod 5 slides in the arc limit groove 13 until the end of the limit rod 5 is located at the rear end of the arc limit groove 13, indicating that the bracket 3 has been flipped into place. Please refer to Figure 3 On the contrary, when the seat bag 20 fixedly connected to the bracket 3 needs to return upward, after the seat bag 20 loses the riding force, under the restoring action of the spring 4, a power source is provided for the bracket 3 to flip upward, thereby driving the bracket 3 and the seat bag 20 to reset. Similarly, when the end of the limiting rod 5 slides to the front end of the arc-shaped limiting groove 13, it means that the bracket 3 and the seat bag 20 have returned to their positions. In the above-mentioned flipping and resetting assembly, except that the round seat 1 needs to be fixedly connected to the support arm 10 and is therefore located outside the seat bag 20, other components are all arranged inside the seat bag 20. The seat bag 20 and the round seat 1 can be used to shield the limiting structure formed by the limiting rod 5 and the arc-shaped limiting groove 13, so as to improve the safety performance of the seat bag 20 during the flipping or restoring process, and also improve the overall aesthetics of the seat.

[0028] See also Figure 3 and Figure 4 In some embodiments, the bracket 3 includes a first vertical plate 31 and a second vertical plate 32 which are arranged in parallel on the left and right sides, and a horizontal plate 33 for connecting the tops of the first vertical plate 31 and the second vertical plate 32; the first vertical plate 31 and the second vertical plate 32 are respectively perpendicular to the horizontal plate 33; the fixed shaft 2 passes through the left and right side walls of the first vertical plate 31 and the second vertical plate 32; the limiting rod 5 is respectively fixed to the first vertical plate 31 and the second vertical plate 32; and the end of the spring 4 abuts against the lower surface of the horizontal plate 33. The frame structure of the bracket 3 is formed by the first vertical plate 31, the second vertical plate 32 and the horizontal plate 33, which has the characteristics of light weight and can meet the structural strength, and the hollow frame structure is convenient for installing the spring 4 on the fixed shaft 2. Specifically, the bracket 3 is formed by bending a plate. The limiting rod 5 can be welded to the first vertical plate 31 and the second vertical plate 32 to achieve the fixed connection between the limiting rod 5 and the bracket 3. A space for the spring 4 to deform is formed between the first vertical plate 31 and the second vertical plate 32.

[0029] See also Figure 3 and Figure 4In some embodiments, a damper 6 is fixedly connected to one end of the fixed shaft 2, and the damper 6 is arranged on the end of the fixed shaft 2 away from the round seat 1; the first vertical plate 31 and the second vertical plate 32 are respectively fixedly connected to the same horizontally extending connecting shaft 61, and the end of the connecting shaft 61 is fixedly connected to the damper 6. The damper 6 slows down the speed of the spring 4 restoring its deformation, thereby preventing the spring 4 from driving the seat bag 20 to reset too quickly and generating a loud noise. The connecting shaft 61 is set to connect the damper 6 and the bracket 3, so that the damper 6 is driven to rotate synchronously when the bracket 3 flips.

[0030] See also Figure 3 and Figure 4 In some embodiments, the fixed shaft 2 is further provided with a first limiting sleeve 21 and a second limiting sleeve 22, the first vertical plate 31 is rotatably connected to the first limiting sleeve 21, and the second vertical plate 32 is rotatably connected to the second limiting sleeve 22. The first limiting sleeve 21 and the second limiting sleeve 22 are both used to limit the displacement of the bracket 3 in the left and right directions, and can also play a role in silencing, that is, to prevent the bracket 3 from having a hard collision with the fixed shaft 2.

[0031] See also Figure 4 In some embodiments, a polygonal protrusion 23 is provided at one end of the fixed shaft 2, and a socket 11 matching the shape of the polygonal protrusion 23 is provided on the round seat 1, and the polygonal protrusion 23 is located in the socket 11. During assembly, the end of the fixed shaft 2 provided with the polygonal protrusion 23 is inserted into the socket 11, so that the fixed shaft 2 and the round seat 1 can be initially fixed, and the assembly is convenient and quick.

[0032] See also Figure 4 In some embodiments, a nut groove 12 is formed on the round seat 1, and the nut groove 12 passes through the left and right side walls of the round seat 1, and a nut (not shown in the figure) is fixed in the nut groove 12; please refer to Figure 1 The arm 10 is provided with a mounting hole 101 corresponding to the nut slot 12, and a bolt or a screw is arranged in the mounting hole 101, and the rod of the bolt or the screw is threadedly connected with the nut.

After the bolt or the screw passes through the mounting hole 101, the rod of the bolt or the screw is threadedly connected with the nut in the nut slot 12, thereby achieving the locking of the arm 10 and the round seat 1.

[0033] See also Figure 1 The utility model also provides a seat bag recovery structure, including the flip reset assembly and the seat bag 20, the flip reset assembly is set to two symmetrically, and the two flip reset assemblies are both located inside the seat bag 20. Figure 2 Specifically, under the premise that one damper 6 can slow down the restoring speed of the seat bag 20, the damper 6 is only provided on one of the flip reset assemblies in this embodiment, that is, the damper 6 is not provided on the other flip reset assembly. Compared with the existing structure that needs to use a connecting rod to connect the two reset structures, the above structure can eliminate the setting of the connecting rod, so that the thickness of the seat bag 20 can be made thinner.

[0034] Specifically, the flip reset assembly can be pre-assembled before leaving the factory. After being transported to the installation site, the flip reset assembly can be quickly installed on the corresponding support arm 10 by directly cooperating with the nut on the round seat 1 through bolts or screws, and then the seat bag 20 can be installed on the flip reset assembly, so that quick assembly can be achieved, which can greatly save the time of on-site assembly.

[0035] In some embodiments, the seat bag 20 is a plastic seat bag, that is, the seat bag 20 is an injection molded product. Figure 1 The seat bag 20 comprises a bottom plate 201 and a seat plate 202 which are fixed to each other. The bottom plate 201 or the seat plate 202 is pre-formed with embedded parts by injection molding, and the bottom plate 201 and the seat plate 202 can be quickly assembled by the embedded parts. The lower surface of the seat plate 202 is fixed to the upper surface of the bracket 3 in the flip reset assembly; please refer to Figure 5 The inner cavity of the bottom plate 201 is provided with a hook portion 2011 extending upward, and the bracket 3 is provided with a groove 34 for the hook portion 2011 to pass through, and the hook portion 2011 is arranged in the groove 34. The arrangement of the hook portion 2011 improves the connection stability between the bottom plate 201 and the bracket 3.

[0036] See also Figure 1 In some embodiments, the middle of the seat plate 202 is recessed toward the bottom plate 201. As described above, since the traditional connecting rod is eliminated, the thickness of the seat bag 20 can be set to be thinner, and since there is no obstruction of the connecting rod, a deeper recess can be formed on the thinner seat bag 20 to meet the human mechanics and improve the comfort of the passengers.

[0037] In summary, the utility model uses the seat bag 20 and the round seat 1 to shield the limiting structure formed by the limiting rod 5 and the arc-shaped limiting groove 13, so as to improve the safety performance of the seat bag 20 during the flipping or restoring process, and also improve the overall aesthetics of the seat. The flipping and resetting assembly is provided with a bracket 3 fixed to the seat bag 20, a fixed shaft 2 that allows the bracket 3 to rotate, and a spring 4 that provides a power source for the bracket 3 to reset, so that the bracket 3 can drive the seat bag 20 to flip downward or reset upward. The seat bag recovery structure can eliminate the setting of the connecting rod by providing two symmetrical flipping and resetting assemblies, so that the thickness of the seat bag 20 is thinner, and the on-site assembly time of the entire seat can be shortened.
