[0039] Example

[0040] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a wheelchair area guardrail mounted folding chair structure, including an upper support rod 10, a lower support rod 11, a mounting frame 12 and a flip seat 13.

[0041] Specifically, the upper support rod 10 is arranged on the top surface of the mounting frame 12, and the lower support rod 11 is arranged on the bottom surface of the mounting frame 12, and at least one lower support rod 11 is provided. In a preferred embodiment, there is one lower support rod 11, and the upper support rod 10 and the lower support rod 11 are arranged vertically on the same straight line and close to a vertical rod of the mounting frame 12, that is, the upper support rod 10, the lower support rod 11 and the mounting frame 12 are arranged in a T-shape. The flip seat 13 is installed on the mounting frame 12. In order to make the flip seat 13 adapt to the body size of different passengers, the seat surface of the flip seat 13 has a height distance of 38cm to 45cm from the aisle in the vehicle. In addition, mounting parts 101 are provided on the top end of the upper support rod 10, the bottom end of the lower support rod 11 and a vertical rod of the mounting frame 12. The mounting frame 12 is connected to the vehicle body through the mounting parts 101 to ensure the stability of the connection between the mounting frame 12 and the vehicle body. The mounting parts 101 can be locked and connected to the vehicle body with a double-bolt structure, which is more firm and reliable. An optional mounting part 101 is the AP-32001 straight seat.

[0042] Thus, by providing the flip seat 13 on the mounting frame 12, the flip seat 13 can be opened to accommodate passengers or flipped and folded, thereby facilitating adjustment according to the number of passengers in the vehicle and changes in their needs, thereby optimizing barrier-free design. Specifically, the flip seat 13 can be opened to accommodate passengers; when folded, it can free up space for wheelchairs. When there are no special passengers in the vehicle, more standing room can also be provided for ordinary passengers during peak hours. The mounting frame 12, upper support rod 10, and lower support rod 11 can also be used as handrails.

[0043] like Figure 3 As shown, in this embodiment, the mounting frame 12 includes a frame body 121, a mounting rod 122 and a mounting plate 123. The upper support rod 10 is arranged on the top surface of the frame body 121, and the lower support rod 11 is arranged on the bottom surface of the frame body 121. The mounting rod 122 and the mounting plate 123 are arranged in the frame body 121 for installing the flip seat 13. A plurality of mounting holes 1221 for installing the flip seat 13 are provided on the mounting rod 122 and the mounting plate 123. The flip seat 13 can be locked and connected with the mounting rod 122 and the mounting plate 123 by bolts to ensure that the flip seat 13 can be stably and firmly installed on the mounting frame 12 to avoid loosening during vehicle driving.

[0044] like Figure 3 As shown, in this embodiment, a plurality of weight-reducing holes 1231 are provided on the mounting plate 123 to reduce the weight of the mounting plate 123 and save production costs.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, the mounting frame 12 also includes a U-shaped armrest rod 124, which is located on one side of the flip seat 13 and is vertically arranged on a vertical rod of the frame 121. In this way, the U-shaped armrest rod 124 and the frame 121 form a closed and stable load-bearing mechanism. Because the frame 121 is arranged between the upper support rod 10 and the lower support rod 11, the frame 121, the upper support rod 10 and the lower support rod 11 are connected to the vehicle body. When the passenger grasps the U-shaped armrest rod 124, the external stress can be transmitted along the U-shaped armrest rod 124 to the frame 121, the upper support rod 10 and the lower support rod 11, and then transmitted to the side end, upper end and lower end of the vehicle body to disperse the stress and have good load-bearing capacity.

[0046] like Figure 1 、 Figure 2 and Figure 3As shown, the horizontal bar at the top of the frame 121 is a first grip bar 1211, and a second grip bar 1212 is provided on the side of the middle of the frame 121 facing away from the flip seat 13. In this way, when the number of passengers in the vehicle is at its peak and there are no special passengers in the vehicle, the flip seat 13 can be folded and stowed, leaving space for ordinary passengers to stand. The first grip bar 1211 is located at the top of the frame 121 and can be used as a handrail for passengers standing. The second grip bar 1212 is located in the middle of the frame 121 and on the rear side of the flip seat 13, and can be used as a handrail for passengers sitting in the seat behind the flip seat 13. The first grip bar 1211 and the second grip bar 1212 provide support for passengers standing and sitting in the vehicle, preventing passengers' bodies from swaying in any direction while the vehicle is in motion, thereby ensuring passenger safety.

[0047] In a preferred embodiment, an anti-slip cover 12111 is provided on the first grip handle 1211 and the second grip handle 1212. The anti-slip cover 12111 is mounted on the first grip handle 1211 and the second grip handle 1212. An optional anti-slip cover 12111 is a rubber cover. The anti-slip cover 12111 increases the friction between the first grip handle 1211 and the second grip handle 1212 and the hand, so that the passenger's hand is not likely to slip when grasping the first grip handle 1211 and the second grip handle 1212.

[0048] like Figure 3 As shown, in this embodiment, the second grip handle, the mounting frame 12 and the upper support rod 10 are integrally formed, and the structure is more stable, while the lower support rod 11 is connected to the mounting frame 12 by a connector for easy disassembly and assembly. An optional connector is the AP-32001 tee.

[0049] like Figure 1 and Figure 2As shown, in this embodiment, the flip seat 13 includes a seat back 131 and a seat 132. The seat back 131 is bolted and fixed on the mounting rod 122. Rotating parts 133 are provided on both sides of the seat 132. The rotating parts 133 include two L-shaped fixing plates. The fixing plates are bolted and fixed on the mounting plates 123. Then, the seat 132 is rotated and installed between the two fixing plates through the rod. The seat 132 and the rod are connected by a torsion spring. In this way, the initial state of the seat back 131 and the seat 132 is in a fitted state. When the seat 132 needs to be flipped to a seatable state, When the flip seat 132 is in the sitting position, a downward force is applied to the seat 132, and the seat 132 is flipped to the sitting position for use. The passenger can sit on the seat 132 to keep the seat 132 in the sitting position; when the seat 132 needs to be folded, the passenger stands up, and the torsion spring provides a rotational force to drive the seat 132 to flip and fit on the seat back 131, so that the seat 132 and the seat back 131 can be automatically folded. When the flip seat 13 is not needed, the flip seat 13 is kept in the closed and folded position under the action of the torsion spring, leaving space for wheelchair parking or for ordinary passengers to stand.

[0050] like Figure 1 and Figure 2 As shown, this embodiment also includes a winding member 14, a locking member 15 and a safety belt body 16 wound in the winding member 14. The winding member 14 is arranged on a vertical rod of the mounting frame 12, and the locking member 15 is arranged on another vertical rod of the mounting frame 12. One end of the safety belt body 16 is provided with a plug connector 161 that is plugged and engaged with the locking member 15.

[0051] Specifically, when not in use, the seat belt body 16 is retracted into the reel 14; when in use, the seat belt body 16 is pulled out and plugged into the buckle 15 to restrain the passenger's displacement, thereby protecting the passenger from injury caused by collision when the vehicle collides or brakes suddenly.

[0052] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
