[0032] Specifically, the torsion spring 19 brings the connecting rods 3 18 on both sides together, so that the columnar pin 20 fixedly connected to the bottom end of the connecting rod 3 18 engages with the cylindrical slot 13 provided in the rear wheel 23, so that the rear wheel 23 is stuck and cannot rotate. The handle bar 7 is lifted to press the connecting rod 8 and the connecting rod 1 9 downward, thereby driving the connecting rod 2 11 to move downward, and then through the rotating shaft 2 14 fixedly connected to the bottom end of the connecting rod 2 11, the rotating disk 15 rotatably connected to the inner side of the rotating shaft 2 14 is rotated to both sides, driving the connecting rod 3 18 fixedly connected to the rotating disk 15 to rotate at the same time to offset the pulling force of the torsion spring 19, thereby unlocking the mechanism.

[0036] Specifically, when the current rotating column 204 rotates, it will drive the circular gear four 224 fixedly connected to it to rotate, thereby driving the circular gear one 212 meshing with it to rotate, and then the transmission shaft one 209 fixedly connected to the circular gear one 212 rotates, and then drives the transmission shaft two 214 and the transmission shaft three 222, so that the circular gear three 217 rotates accordingly, so as to make the rear rotating column 218 fixedly connected to it rotate. Because the bevel gear three 207, the bevel gear five 220 and the bevel gear six 221 have the same size and the same number of gears, and the bevel gear four 208 and the bevel gear three 207, the bevel gear five 220, and the bevel gear six 221 have different gear ratios, and the transmission ratio is not one, the degree of rotation of the front rotating column 204 is greater than the degree of rotation of the rear rotating column 218, and the rotation causes the bottom plate two 219 fixedly connected to the rear rotating shaft and the parts fixedly connected thereon to rotate in an upwardly tilted state.

[0037] Please see attached Figure 3 -Attached Figure 5 The upper end of the second bottom plate 219 is fixedly connected with a U-shaped baffle 29, and handles 28 are fixedly connected to both sides of the top of the U-shaped baffle 29.

[0038] Specifically, by using the universal shaft 27 and the front rotating shaft 16 in cooperation, the front wheel 10 can rotate in different directions when moving forward or backward to achieve the purpose of turning. The U-shaped baffle 29 can better protect the passengers and can also effectively carry the storage space storage slot 25, and the handle 28 installed thereon can also help the passengers to fix their positions more safely.

[0039] Working principle: First, when in a stationary state, the torsion spring 19 pulls the connecting rod 3 18 fixedly connected on both sides toward the middle, so that the columnar latch 20 fixedly connected to the end of the connecting rod 3 18 is engaged in the cylindrical slot 13, so that all the rear wheels 23 are locked. At this time, the grip 7 is pulled upward, and the end thereof fixedly connected to the connecting rod 8 will move downward around the rotating shaft 1 6, driving the connecting rod 8 and the connecting rod 1 9 fixedly connected thereto to move downward, so that the connecting rod 2 11 fixed at both ends of the connecting rod 1 9 moves downward. Because the connecting rod 2 11 is rotatably connected to one side of the rotating disk 15 through the rotating shaft 2 14, when the connecting rod 2 11 moves downward, it will drive the two rotating disks 15 to move in opposite directions. , so that the connecting rod 3 18 fixedly connected to the side of the rotating disk 15 rotates together with it, so that the columnar latch 20 leaves the cylindrical slot 13, and the rear wheel 23 is unlocked and rotated, thereby achieving hand release and stop, press and go, which is convenient and fast while enhancing safety and protection. When no one is watching, it prevents sliding on the slope or sliding on the plane due to other external forces, making it more practical and safe; the side rotating column 203 is rotated counterclockwise, so that the side baffle 201 fixedly connected to it rotates together, and the bevel gear 1 205 fixedly connected to the other end of the side rotating column 203 rotates in the same direction at the same time, and the bevel gear 206 meshing with the bevel gear 1 205 is driven to rotate counterclockwise, so that the side baffle 201 fixedly connected to it rotates together, and the bevel gear 1 205 fixedly connected to the other end of the side rotating column 203 rotates in the same direction at the same time, and the bevel gear 206 meshing with the bevel gear 1 205 is driven to rotate counterclockwise, so that The front rotating column 204 rotates in the same direction, driving the front baffle 202 to rotate, so that the side baffles 201 on both sides fall down and when the front rotating column 204 rotates counterclockwise, the circular gear 4 224 located in the middle thereof and fixedly connected to it rotates in the same direction at the same time, so that the circular gear 1 212 meshing with the circular gear 4 224 rotates clockwise in the opposite direction, and the transmission shaft 1 209 fixedly connected to the center of the circular gear 1 212 rotates in the same direction, driving the bevel gear 4 208 fixedly connected at the other end thereof to rotate in the same direction, thereby making the bevel gear 3 207 meshing with the bevel gear 4 208 rotate in the same direction, so that the transmission shaft 2 214 fixedly connected at one end thereof rotates in the same direction, driving the transmission shaft 214 fixedly connected at the other end thereof to rotate The bevel gear six 221 connected to the bevel gear six 221 rotates in the same direction, thereby making the bevel gear five 220 fixedly connected to the bevel gear six 221 rotate in the same direction, and the transmission shaft three 222 one end of which is fixedly connected to the bevel gear five 220 is driven to rotate in the same direction at the same time, and the circular gear two 216 fixedly connected to the transmission shaft three 222 at the center rotates in the same direction, and the circular gear three 217 meshing with the circular gear two 216 rotates counterclockwise in the opposite direction, and finally the rear rotating column 218 fixedly connected to the circular gear three 217 rotates, and vice versa, the handle 211 is rotated to restore the mechanism, thereby achieving the purpose of conversion from a bed to a car, and the process is simple and fast, which increases its practicality, enriches its uses, and broadens its original usage scenarios.
