Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a foldable seat in a passenger compartment of a subway vehicle. Background Art

[0002] The subway is a fast and convenient urban public transportation tool that usually runs in underground tunnels, effectively alleviating the pressure of ground traffic. With its large capacity and high efficiency, it provides a comfortable travel environment for urban residents, connects major areas of the city, and promotes economic and cultural exchanges. Subway stations are modern in design and well-equipped, providing passengers with convenient transfer and travel services. It is an indispensable part of modern urban life.

[0003] Some subway passengers carry suitcases or other large items. When passengers are seated, there is usually no suitable place to store the luggage, so the luggage is placed in the aisle inside the vehicle compartment. When the subway starts or stops, the luggage may continue to move due to inertia, and may hit other passengers, posing a certain safety hazard. Therefore, a foldable seat in the passenger compartment of a subway vehicle is proposed to solve the above problem. Utility Model Content

[0028] like Figure 1-5As shown, a foldable seat in a passenger compartment of a subway vehicle includes a support mechanism 1, a seat body 2 is provided on one side of the support mechanism 1; the seat body 2 also includes: a backrest 201, a seat cushion 202 is fixedly installed at the lower end of the backrest 201, both sides of the bottom surface of the seat cushion 202 are fixedly connected to clamping members 208, and a buffer plate 209 is fixedly connected to the inner side of the bottom surface of the backrest 201 and close to the clamping member 208; wherein, the inner sides of the two clamping members 208 are symmetrically connected to the rotating shaft 211, and the rotating shaft 211 and the clamping member 208 are fixedly connected. A gasket is used to increase the damping. An anti-collision plate 210 is fixedly installed between the symmetrical rotating shafts 211. The anti-collision plate 210 is located on the side away from the rotating shaft 211 and is fixedly connected to a connecting block 212. The inner wall of the connecting block 212 is provided with a socket 213. Among them, the surface of the anti-collision plate 210 is provided with an opening 214. The inner side wall of the opening 214 is fixedly connected to a connecting rod 215. The connecting rod 215 is located on the same straight line as the two rotating shafts 211. A transmission wheel 216 is fixedly installed in the middle of the outer wall of the connecting rod 215. Figure 3 As shown, the inner side of the transmission belt 217 is toothed, and the outer sides of the transmission wheel 1 216 and the transmission wheel 2 219 have convex teeth that match the transmission belt 217, so that the transmission wheel 1 216 and the transmission wheel 2 219 are engaged with the transmission belt 217, thereby improving the stability of the transmission;

[0029] The buffer plate 209 extends in the vertical direction as a whole. A rubber pad is fixedly connected to one side of the buffer plate 209 close to the anti-collision plate 210, and the surface of the buffer plate 209 is in active contact with the anti-collision plate 210. Figure 3 As shown, after the anti-collision plate 210 is turned outward 90 degrees around the rotation axis 211, the anti-collision plate 210 contacts the rubber pad.

[0030] A gear 218 is symmetrically connected to the middle of the inner wall of the backrest 201, and the two gears 218 are meshed with each other. A transmission wheel 219 is fixedly installed in the middle of the gears 218. The outer side of the transmission wheel 219 is connected with a transmission belt 217. The transmission belt 217 is located on the side away from the transmission wheel 219 and is connected with the transmission wheel 1 216. The transmission belt 217 is connected to the bottom surface of the backrest 201 through the bottom surface. Figure 3 As shown, under meshing action, the two gears 218 rotate simultaneously and in opposite directions;

[0031] A limiting sleeve 203 is fixedly installed in the middle of the front end of the bottom of the seat cushion 202, and an inner wall sliding sleeve of the limiting sleeve 203 is provided with an insert shaft 205, one end of the insert shaft 205 extends to the front of the limiting sleeve 203 and is fixedly connected to a pull ring 204, and the other end of the insert shaft 205 is connected through each connecting block 212, and a ring 206 is fixedly connected to the middle of the insert shaft 205, and a spring 207 is also sleeved on the middle of the insert shaft 205, one side of the spring 207 is fixedly connected to the ring 206, and the other side of the spring 207 is fixedly connected to the limiting sleeve 203, as shown in FIG. Figure 5 As shown, the spring 207 pushes the ring 206, thereby driving the insertion shaft 205 to insert into the insertion hole 213;

[0032] The support mechanism 1 includes a fixed plate 101, an upper end of which is fixedly mounted an indicator sign 102, a surface of the fixed plate 101 and a support block 103 located below the indicator sign 102, an upper outer wall of the support block 103 being fixedly mounted to the backrest 201, and a lower outer wall of the support block 103 being fixedly mounted to the seat cushion 202. Figure 2 As shown, the sign 102 can be used to mark the method of use of the present invention.

[0033] The working principle of this utility model:

[0034] Before taking their seats, passengers pull the pull ring 204 outward according to the sign 102, so that the insertion shaft 205 is withdrawn from each insertion hole 213. Then, the passenger pushes the anti-collision plate 210 on either side to flip outward. Since the rotating shaft 211 and the transmission wheel 1 216 rotate around the same center, the transmission belt 217 drives the transmission wheel 2 219 on the other side to rotate, and the gear 218 rotates. Under the action of mutual meshing, the two gears 218 rotate in opposite directions, and then the transmission belt 217 on the other side drives the non-contact anti-collision plate 210 to unfold outward.

[0035] Secondly, until the anti-collision plate 210 contacts the buffer plate 209, the overall length direction of the anti-collision plate 210 is perpendicular to the floor of the car, and the damping between the rotating shaft 211 and the clamping member 208 fixes the anti-collision plate 210. Then the passenger pushes the luggage under the seat cushion 202. When the passenger sits down, the passenger's legs, the anti-collision plates 210 on both sides and the fixed plate 101 jointly limit the luggage, thereby preventing the luggage from moving due to inertia when the vehicle is driving.

[0036] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
