[0029] Embodiment 1

[0030] As Figure 1-2 shown, the present invention provides a technical solution: a wheelchair fixing device for a carriage, including a wheelchair fixing component, a clamping component, and a control component;

[0031] The wheelchair fixing component is a baffle 3 for fixing the position of the wheelchair wheels, and the baffle 3 moves on the slide rail 1 through the slider 2;

[0032] Specifically, as Figure 3As shown in the figure, the baffle 3 includes an interface surface 301 fixed to the slider 2, where: the interface surface 301 is adapted to the contact surface of the wheelchair wheel to ensure close cooperation between the two. When the interface surface 301 is fixed to the slider 2 with screws, it serves to prevent the wheelchair from slipping left and right and allows for adjustment or disassembly when needed; perpendicularly fixed at both ends of the interface surface 301 are an inner baffle 302 and an outer baffle 303, and the height of the inner baffle 302 is higher than that of the outer baffle 303; in this way, when fixing the wheelchair wheel, the positions where the two inner baffles 302 are located play a limiting role and can adapt to wheelchair wheels with different fixing supports and sizes, having wide applicability. Additionally, an anti-slip sheet is installed on the side of the baffle 3 close to the wheelchair to prevent the risks of the wheelchair slipping forward and backward and side-slipping, and the fixing of the wheelchair is achieved under the limiting effect of the baffle.

[0033] The clamping assembly includes a cylinder 5. The output end of the cylinder 5 is connected to the mounting hole 304 of the baffle 3 through a pneumatic rod 4. The air inlet and outlet of the cylinder are connected to a three-position five-way solenoid valve through a trachea. The solenoid valve is connected to the corresponding control button of the control assembly through a wire, and the air inlet of the solenoid valve is connected to an air pump. The movement state of the cylinder is controlled by the control button. When the button is pressed for the first time, the pneumatic rods 4 at both ends squeeze towards the middle, driving the corresponding sliders 2 to slide and reducing the distance between the two baffles 3 to achieve the effect of clamping the wheelchair wheel; when the button is pressed for the second time, the pneumatic rod maintains the current clamping position to fix the wheelchair wheel; when the button is pressed for the third time, the pneumatic rod 4 contracts, driving the two baffles 3 to separate and release the wheelchair wheel.

[0034] The two cylinders 5 are respectively fixed to the side wall of the carriage under the seat through a base 6. A fixed mounting piece is provided on the side of the base 6, which facilitates marking the hole positions during the installation process. Based on the marked hole positions, it is ensured that the length direction of the slide rail 1 is parallel to the telescopic direction of the pneumatic rod 4, resulting in the sliders 2 being unable to move normally; reducing unnecessary errors that affect the operation experience.

[0035] The control assembly includes a control button installed on the armrest on the side of the seat for easy operation by the passenger.

[0036] Embodiment 2

[0037] Refer to Figure 4-5, a seat for a wheelchair fixing device in a carriage. The parts not detailed in the present utility model are as shown in Embodiment 1. The wheelchair fixing device described in Embodiment 1 can be installed in a subway carriage to facilitate fixing the position of the wheelchair. However, in life, passengers who do not need to use wheelchairs account for a larger proportion. Therefore, when the carriage wheelchair fixing device is not needed, a seat for normal use is provided at this place to reduce waste of resources. The seat described in this embodiment is different from the original carriage seat. The seat surface 10 of the seat can be lifted and fitted with the backrest 20 and retracted, and is fixed by magnetic attraction to provide a seat space for parking the wheelchair. The wheelchair clamping body is installed on the side wall directly below the seat;

[0038] The seat includes a seat surface 10, and the seat surface 10 is fixed to the bottom of the backrest 20 through a rotating connector 30. A magnetic attraction member is provided on the seat surface 10.

[0039] Specifically, during use, the seat surface 10 is retracted and leaned against the backrest 20. The seat surface 10 is fixed in the retracted state due to magnetic attraction. After the passenger parks the wheelchair in the seat position, press the control button at the position of the seat armrest. The wheelchair clamping body located under the seat starts to work. The cylinder 5 starts to work, the pneumatic rod 4 extends, driving the slider 2 to move towards the middle, and the baffle 3 also moves towards the middle. The right baffle 3 presses against the right wheel of the wheelchair, and the left baffle 3 presses against the left wheel of the wheelchair, clamping both sides of the wheelchair. The passenger presses the button again, and the pneumatic rod 4 stops moving and is fixed in the clamping position. At this time, the wheelchair is fixed at the seat position. When the passenger is about to get off the vehicle, press the button again. The cylinder 5 starts to work, the pneumatic rod 4 contracts, driving the baffle 3 and the slider 2 to move towards both sides. At this time, the baffle 3 releases the wheelchair, and the passenger can leave on their own. For the seat, just pull down the seat surface 10 by hand to restore the seat to the open state;

[0040] More specifically, in order to ensure the stability of the installation of the seat surface 10 and the backrest 20, the principle of triangular fixation is adopted on its side. The diagonal brace 40 is used. One end of the corresponding diagonal brace 40 is fixed on the seat surface 10, and the other end is fixed in the chute on the side of the backrest 20. Based on the fixation at different positions of the chute, it plays a role of triangular support.

[0041] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
