The movable support comprises a first transmission rod 6, a second transmission rod 7, a third transmission rod 8 and a fourth transmission rod 9. The first transmission rod 6 and the fourth transmission rod 9 are rotatably connected with the main board 1, the common end of the first transmission rod 6 is rotatably connected with the common end of the second transmission rod 7, the common end of the first transmission rod 6 and the common end of the second transmission rod 7 are rotatably connected with the seat plate 5, the common end of the third transmission rod 8 is rotatably connected with the common end of the fourth transmission rod 9, the common end of the third transmission rod 8 and the common end of the fourth transmission rod 9 are rotatably connected with the seat plate 5, the common end of the second transmission rod 7 is rotatably connected with the common end of the third transmission rod 8, and the common end of the second transmission rod 7 and the common end of the third transmission rod 8 are movable ends of the movable support.

The inside side of mainboard 1 has seted up movable groove 21, and the front side of third spout 16 is opened and is equipped with second through-groove 23, and second through-groove 23 communicates with each other with movable groove 21, and first logical groove 20 has all been seted up to the front end both sides of mainboard 1, and first logical groove 20 communicates with each other with movable groove 21. The front side fixedly connected with Y shape bracing piece 18 of second slider 17, spring 19 has been cup jointed in the outside of Y shape bracing piece 18, and spring 19's one end and third spout 16 fixed connection, spring 19's the other end and second slider 17 fixed connection. The Y-shaped support bar 18 passes through the second through slot 23 and within the first through slot 20. A clamping groove 24 is formed in the bottom end of the second sliding block 17, a rotating groove 25 is formed in the main board 1 below the third sliding groove 16, a clamping block 26 is rotationally connected in the main board 1 and located in the rotating groove 25, a torsion spring is arranged on a rotating shaft of the clamping block 26, and the clamping block 26 is matched with the clamping groove 24.

The front end of mainboard 1 rotates the erection joint to be connected with connecting rod 2, the first gyro wheel 22 of bottom fixedly connected with of connecting rod 2, the bottom rear side fixed mounting second gyro wheel 29 of mainboard 1. The main board 1 is also provided with a battery and a controller, the second roller 29 is a motor-driven roller, the battery and the controller are electrically connected with the second roller 29, and the handle 3 is provided with a knob type handle as a vehicle speed regulator to be connected with the controller.

The top fixedly connected with handle 3 of connecting rod 2, one side of handle 3 is equipped with manual brake 4, and the brake cable and fixture block 26 fixed connection of manual brake 4, the both sides of activity groove 21 all are equipped with second bracing piece 27, and the one end and the mainboard 1 of second bracing piece 27 rotate to be connected, and the both sides of Y shape bracing piece 18 all rotate and are connected with movable rod 28 one end, and the other end and the second bracing piece 27 of movable rod 28 rotate to be connected.

When the first roller 22 of the scooter collides with an obstacle during driving, the first roller 22 cannot advance due to blocking, and the second roller 29 is lifted upwards due to inertia, so that the scooter falls forward.

In order to avoid this situation, the user only needs to press the handbrake 4, and the handbrake 4 pulls the fixture block 26 to rotate through the brake cable action, so that the fixture block 26 is separated from the clamping groove 24 on the second sliding block 17, and the second sliding block 17 is in a movable state at this moment.

Under the effect of user's gravity, make the rear side of seat 5 have decurrent effort, because worker's shape pole 13 is connected with the rotation of driving plate 12 to first slider 11 and the spacing sliding connection mode of second spout 10 can make worker's shape pole 13 pass through second spout 14 on the mainboard 1 and move down, worker's shape pole 13 drives ground grabbing hook 15 and removes, makes ground grabbing hook 15 and ground contact play the effect of grabbing ground.

When the seat plate 5 inclines forwards or backwards, the second slide block 17 can move forwards through the rotating fit among the first transmission rod 6, the second transmission rod 7, the third transmission rod 8 and the fourth transmission rod 9, the second slide block 17 drives the Y-shaped support rod 18 to move, and the Y-shaped support rod 18 extends out of the vehicle and contacts with an obstacle, so that the support effect is achieved. When the Y-shaped supporting rod 18 moves outwards, the movable rod 28 is in running fit with the second supporting rod 27, so that the second supporting rod 27 can move from the first state to the second state, and can play a supporting role together with the Y-shaped supporting rod 18 to prevent the vehicle body from toppling forwards.

The spring 19 can play a role of buffering and a role of resetting the second slide block 17.

Example 2

The difference lies in with embodiment 1, movable support includes third transfer line 8, and movable support's expansion end is second slider 17, and third transfer line 8 rotates with second slider 17 to be connected, and 5 front ends of seat rotate with connecting rod 2 to be connected, and 5 bottoms of seat rotate with third transfer line 8 to be connected, and sliding sleeve 30 is equipped with on connecting rod 2, and connecting rod 2 divide into upper portion pole and lower part pole, and upper portion pole and lower part pole rotate through the pivot to be connected, and the pivot is located 1 top 3cm departments of mainboard, and the sliding sleeve height is not less than 5 cm.

During assembly, the sliding sleeve 30 is tightly matched with the connecting rod 2, so that the sliding sleeve 30 can be sleeved on the connecting rod 2 without falling down, manual operation is needed, the sliding sleeve 30 is in a rotating shaft or is far away from the rotating shaft, and the upper rod and the lower rod of the connecting rod 2 are folded or in a linear state.

The upper portion pole accessible pivot and the mainboard 1 of connecting rod 2 are fold condition, simultaneously, because be connected for rotating between seat 5 and the connecting rod 2, be connected for rotating between seat 5 and the third transfer line 8, be connected for rotating between third transfer line 8 and the second slider 17, and sliding connection between second slider 17 and the mainboard 1. A quadrilateral structure is formed among the connecting rod 2, the seat plate 5, the third transmission rod 8 and the main plate 1, so that the foldable state is realized, and the carrying is convenient.

The I-shaped rod 13 can be arranged under the seat plate 5 as in embodiment 1, so that the hook claw of the I-shaped rod 13 to the ground can be realized.
