[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A mechanical front hatch opening escape device, installed at the front of a car, comprises:

[0008] A front hatch, wherein a hinge is provided at the top of the front hatch, the front hatch is hinged to the roof of the car by means of the hinge, a hatch lock is fixed on the bottom inner wall of the front hatch, and a hatch lock tongue cooperating with the hatch lock is fixed on the bottom bracket of the car;

[0009] An emergency switch assembly, the emergency switch assembly comprising a switch handle, a rotating blade and an emergency switch mechanism, the rotating blade being a fan-shaped sheet structure, and the bottom end surface of the rotating blade being rotatably connected to the inner wall of the front door, the switch handle being fixed to the top end surface of the rotating blade, the emergency switch mechanism being rotatably connected to the inner wall of the front door, one end of which abuts against the bottom of the rotating blade, and the other end being fixedly connected to the door lock;

[0010] A middle seat backrest bracket, the middle seat backrest bracket is located in the middle of the inner wall of the front door, and the front end surface of the middle seat backrest bracket is arranged perpendicular to the front door, a bracket lock is fixed to the bottom of the rear end surface of the middle seat backrest bracket, and a bracket lock tongue that cooperates with the bracket lock is fixed on the bracket at the bottom seat of the car;

[0011] A backrest bracket switch assembly is rotatably connected to the middle seat backrest bracket and is arranged close to the front end surface of the middle seat backrest bracket, with one end abutting against the inner wall of the front door and the other end fixedly connected to the bracket lock.

[0012] It can be known from the above technical solutions that, compared with the existing technical solutions, the present invention discloses a mechanical front hatch door opening escape device, which can hinge the top of the front hatch door to the roof of the car by using a hinge, and by turning the switch handle, the rotating blade can be driven to rotate, thereby driving the emergency switch mechanism to open the hatch door lock, and the front hatch door can be opened from the bottom of the front of the car to facilitate the escape of passengers. By using the abutment structure between the middle seat backrest bracket and the front hatch door, the backrest bracket switch assembly can be driven to open the bracket lock after the front hatch door is opened, so that the passengers can push the middle seat backrest bracket out from the inside of the car, providing passengers with a larger escape passage. The mechanical front hatch door opening escape device of the present invention is not only simple in structure, reasonable in design, and easy to operate, but also can provide passengers with a larger escape space, which is convenient for passengers to escape quickly and safely, and has good market application prospects and high promotion value.

[0013] Furthermore, there are more than two hinges, and the more than two hinges are symmetrically arranged on the top of the front door.

[0014] The beneficial effect of adopting the above technical solution is that the escape device has a reasonable structural design and strong structural stability.

[0015] Furthermore, the emergency switch mechanism includes a connecting plate and a first brake line. The connecting plate is rotatably connected to the inner wall of the front door, one end of which abuts under the rotating blade, and the other end is fixedly connected to one end of the first brake line. The other end of the first brake line is fixedly connected to the door lock.

[0016] The beneficial effect of adopting the above technical solution is that the structure design of the escape device is reasonable. By turning the switch handle counterclockwise, the rotating blade can be driven to rotate counterclockwise. During the rotation of the rotating blade, the connecting plate is pressed down, driving the connecting plate to rotate clockwise, thereby tightening the first brake line at the end of the connecting plate and opening the hatch lock at the bottom of the first brake line.

[0017] Furthermore, the emergency switch assembly also includes a limiting base frame, which is fixed to the inner wall of the front door and is located around the rotating blade, and is used to limit the rotating blade from rotating in a clockwise direction.

[0018] The beneficial effect of adopting the above technical solution is that the rotating blades and the switch handle can be restricted from rotating in the clockwise direction, so that the overall structure of the escape device is compact.

[0019] Furthermore, it also includes a detection component, which includes a detection contact and a detection switch, the detection contact and the detection switch are both fixed on the inner wall of the front door, and the detection contact is located on one side of the rotating blade, the detection switch is located below the rotating blade and arranged opposite to the connecting piece, the detection contact is connected to the input end signal of the detection switch, and the output end of the detection switch is connected to the control room signal, and the control room is used to control the emergency parking of the vehicle.

[0020] The beneficial effect of adopting the above technical solution is that after the rotating blade rotates counterclockwise to the detection contact, the detection contact sends a rotation signal to the detection switch, and the detection switch feeds back the detection signal to the control room, which controls the emergency stop of the car, thereby making the structure design of the escape device reasonable and compact.

[0021] Furthermore, a reinforcing gasket is fixed on the inner wall of the front door, and the reinforcing gasket is arranged opposite to the middle seat back bracket, and the back bracket switch assembly comprises a rotating rod, a connecting rod, a torsion spring, an adjusting plate and a second brake line, one end of the rotating rod is rotatably connected to the side wall of the middle seat back bracket, and the other end is rotatably connected to one end of the connecting rod, the middle part of the connecting rod is rotatably connected to the side wall of the middle seat back bracket, and the other end abuts against the reinforcing gasket, the torsion spring is arranged between the middle part of the connecting rod and the middle seat back bracket, and the torsion direction of the torsion spring is clockwise, one end of the adjusting plate is rotatably connected to the connecting rod, and the other end is rotatably connected to the side wall of the middle seat back bracket, one end of the second brake line is fixedly connected to the other end of the adjusting plate, and the other end is fixedly connected to the bracket lock.

[0022] The beneficial effect of adopting the above technical solution is that the structural design of the escape device is reasonable. Under normal conditions, the other end of the connecting rod abuts against the reinforcing gasket, and the reinforcing gasket applies pressure to the end of the connecting rod, which offsets the torsion force of the torsion spring. When the front door is opened, the pressure disappears, and the connecting rod rotates forward under the torsion force of the torsion spring, thereby driving the adjusting plate to rotate forward, so that the adjusting plate tightens the second brake line and opens the bracket lock at the bottom of the second brake line.

[0023] Furthermore, it also includes a top support assembly, which has two top support assemblies, which are symmetrically arranged and are both hydraulic support rods, one end of which is fixed to the inner wall of the top of the automobile roof and the other end is fixed to the inner wall of the front door.

[0024] The beneficial effect of adopting the above technical solution is that it can provide continuous and stable thrust for the front door after it is opened, assisting passengers to open the front door quickly and effectively, and facilitating passengers to escape quickly and safely.
