The lateral wall that locking hole 15 is close to movable locking piece 5 is provided with and bears pressure platform 151, 5 lateral walls departments of movable locking piece are located bear pressure platform 151 top position and be provided with briquetting 51 down, be provided with ejecting spring 152 on bearing pressure platform 151, ejecting spring 152's top is located briquetting 51 below down and be in compression state after locking hole 15 is packed into at movable locking piece 5.

A separation spring 74 is arranged on the inner wall of the locking hole 15, and the separation spring 74 is in an energy storage state and has a tendency of bouncing the fixed locking piece 6 to separate from the movable locking piece 5; a connecting rope 73 is arranged below the separation spring 74, one end of the connecting rope 73 is fixed on the side wall, and the other end of the connecting rope 73 is connected with the fixed locking piece 6, so that the separation spring 74 is matched to enable the fixed locking piece 6 to keep a position; the connecting cord 73 has a slight recoverable extensibility and is capable of being extended when the movable latch 5 is inserted to deflect the tip of the stationary latch 6; and the original package is recovered after locking.

A top rod 7 stands on the bottom of the locking hole 15, a support 71 is arranged at the top of the top rod 7, a shearing part 72 is arranged at the top of the support 71, the shearing part 72 comprises pole plates arranged on two sides of the connecting rope 73, and the pole plates are electrified to shock the connecting rope 73 to blow the pole plates.

The bottom of the rear cushion part 33 is provided with channel steel 34 with two closed ends, the top end of the support rod 4 is provided with a roller 41, and the roller 41 is positioned in the channel steel 34 to roll after the support rod 4 is jacked up, so that the rear cushion part 33 is jacked up.

The cylinder is adjustable the angle of bracing piece 4, 1 tail end of host computer body is provided with the back cushion 8 that can overturn, back cushion 81 tip is provided with supports end 81, thereby bracing piece 4 pushes up support end 81 bottom will back cushion 8 jack-up upset certain angle.

The outer casing 2 comprises a casing front part 22 and a casing rear part 24, the casing front part 22 is provided with a headlamp 23, and the casing rear part 24 is provided with a reflector.

Two groups of wheels are arranged below the main machine body 1, and a driving device is arranged in the main machine body 1 and drives the wheels to roll; a steering cylinder 11 is arranged above the front side of the main machine body 1, and the steering cylinder 11 controls a group of wheels on the front side to steer; the steering cylinder 11 is connected with a steering shaft 13, and two sides of the steering shaft 13 are provided with extending handles 14.

One driver is generally seated on the beach buggy, and only one passenger is carried. The device provides an adjustable function for comfort, and can provide a comfortable backrest whether only one driver or a passenger is carried.

When only a driver needs to lift the support rod 4, the cylinder drives the support rod 4 to jack up, the top end of the support rod 4 is provided with the roller 41, and the roller 41 is positioned in the channel steel 34 to roll after the support rod 4 is jacked up, and jacks up the rear cushion part 33. Thus, the rear cushion part 33 serves as a backrest of the driver, and is combined with the middle downwardly-bent arc part 31 and the lower foot board, so that the driver can drive the bicycle in a comfortable posture.

When a passenger is seated, the passenger sits on the rear cushion part 33. At this time, the angle of the support rod 4 is adjusted by the air cylinder to be pressed against the bottom of the support end 81 so as to lift and turn the rear cushion 8 by a certain angle, and the rear cushion 8 is used for providing a comfortable backrest for passengers.

The foot pedal 21 is located between the outer casing 2 and the main body 1, so that sand is not brought into the foot pedal 21 when the beach vehicle is running, thereby preventing the shoes of the driver or passengers from entering the sand. In addition, to further block the ingress of sand. The front and rear housing parts 22 and 24 of the device are wider than the body of the outer housing 2, so that the outer housing 2 is concave in the middle when viewed from above.

The device is not hurt when accidents happen in order to protect a driver and passengers. An air bag and a speed reducing umbrella are arranged. The airbag is located at the front cushion portion 32, and the brake parachute is located at the rear cushion portion 33. After the collision is detected, in order to avoid the action of inertia on the personnel, the personnel fly forwards again, thereby causing serious injury. The air bag of the device is popped up to bear the forward impact of personnel, and then the speed-reducing parachute is popped up to reduce the overall speed. The driver sits on the curved portion 31 curved downward in the middle, and can therefore be stably seated on the seat cushion body 3, and can be protected by the airbag and the brake parachute.

In addition, in the event of an accident, the dune buggy may be damaged, resulting in a situation where it is dangerous for the passengers. Thus requiring the person to leave the beach vehicle quickly.

The cushion body 3 of the device is arranged on the main body 1 in a buckling way. After an accidental collision, the cutter 72 is rapidly energized to generate high heat to cut the connecting cord 73. After the connecting rope 73 is broken, the fixed locking member 6 is pushed by the separating spring 74, so that the fixed locking hook cannot catch the movable locking hook 52. I.e. the factor limiting the disengagement of the movable latch 5 disappears. At this time, the movable lock member 5 is pushed out of the lock hole 15 by the push-out spring 152. Thus, the unlocking operation of the seat cushion body 3 is completed.

After the fixed latch 6 is pushed by the separation spring 74, it is bent and the end portion is bounced toward the side wall of the latch hole 15, eventually triggering the switch 150 installed therein. After the unexpected working switch works, the work of the air bag and the brake parachute can be triggered immediately.

The protection work of this device, cooperation set up the installation area on the cushion body 3, the effect is better, can fix the passenger on the cushion body 3 completely to make personnel avoid dashing forward to the collision area, make it avoid the injury.
