[0034] A walking vehicle, the working principle of which is as follows: Example

[0035] The rider gets on the scooter by first standing on it and sitting on the seat. As the action proceeds, the seat portion 2 is stressed, causing the seat bottom plate 21 to move downward. The seat bottom plate 21 moves under the limit of the limit rod 42 and the through hole, and compresses the return spring 43. When the seat bottom plate 21 moves, the second rack 4101 is driven to move downward, and the second rack 4101 drives the fourth gear 41 meshing therewith to rotate, and the overload component 5 is driven to move through the fourth gear 41, and the screw rod 35 is driven to rotate through the second transmission component 44, and the screw rod 35 drives the slider 3501 to move, and then drives the first rack 3601 installed on the slider 3501 to move, and the first rack 3601 drives the third gear 36 meshing therewith to rotate, and drives the second connecting rod to rotate through the first transmission component 37, and drives the second gear 3401 installed on the second connecting rod 34, drives the first gear 3301 meshing with the second gear 3401, drives the first connecting rod 33, and then drives the support plate 32 to move with the first transmission rod 3701, so as to provide auxiliary support for the leg position of the rider; The movement of the second transmission assembly 44 is as follows: The rotation of the overload component 5 drives the fourth bevel gear 4405 installed on the overload component 5 to rotate, thereby driving the third bevel gear 4404 meshing with the fourth bevel gear 4405 to rotate, thereby driving the second transmission rod 4401 to rotate, driving another third bevel gear 4404 to rotate synchronously, driving another fourth bevel gear 4405 to rotate, driving the third transmission rod 4402, and the third transmission rod 4402 drives the sixth bevel gear 4407 installed thereon to rotate, driving the fifth bevel gear 4406 meshing with the sixth bevel gear 4407 to rotate, and the fifth bevel gear 4406 drives the fourth transmission rod 4403 to rotate, synchronously driving another fifth bevel gear 4406 to rotate, driving the sixth bevel gear 4407 meshing with the fifth bevel gear 4406 to rotate, and then driving the screw rod 35 to rotate; The movement of the overload assembly 5 is as follows: The third gear 36 drives the connecting sleeve 51 to rotate, and the spherical member 53 and the abutting spring 54 cooperate to drive the synchronous rod 52; When you need to release the extra power (due to the different body shapes of riders, the position of the support plate 32 is also different): That is, the support plate 32 is already pressed against the leg position. At this time, if the third gear 36 is still rotating, the connecting rod 51 rotates, but the synchronous rod 52 does not rotate. The ball 53 is forced to move toward the inside of the slot and compress the pressing spring 54, so that the connecting rod 51 rotates idly. The movement of the first transmission assembly 37 is as follows: The first gear 3301 drives the support rod 3602 to rotate, and the support rod 3602 drives the second bevel gear 3703 mounted thereon to rotate, driving the first bevel gear 3702 meshing with the second bevel gear 3703 to rotate, thereby driving the first transmission rod 3701 to rotate, causing another first bevel gear 3702 to rotate synchronously, thereby driving another second bevel gear 3703 to rotate, and driving the second connecting rod 34 to rotate; When the seat bottom plate 21 contacts the positioning block 65 (the seat bottom plate 21 ends its downward movement), the push switch 6501 on the positioning block 65 is triggered, and the electromagnetic block 61 is now in a powered-on state (the push switch 6501 is only responsible for the powered-on state of the electromagnetic block 61, and is not responsible for the opening and closing of the electromagnetic block 61), and the electromagnetic block 61 is opened through the pressure sensor 64 (the electromagnetic block 61 is opened when a set weight is detected, and is closed when the weight is lower than the set weight, which is generally set to the minimum weight value for adults aged 18 to 70 years old. This step is integrated in the central processor of the scooter), the electromagnetic block 61 is powered on, and the strong magnetic block 6101 moves under the repulsive force, squeezing the compression spring 63 while driving the locking block 62 to move, so that the locking block 62 is inserted into the locking groove on the limit rod 42, and the limit rod 42 is locked, thereby locking the seat portion 2; When the person stands up, the pressure sensor 64 drives the electromagnetic block 61 to close, driving the locking block 62 to disengage from the locking groove, and the above actions are reset; Example

[0036] The difference between the second embodiment and the first embodiment is that the rotation of the screw rod 35 drives the sliding member to move linearly, driving the auxiliary support member 39 to move toward the legs of the rider.
