Avoid the accumulation of dust or old age in wheeled strollers. When the retaining is not required, the telescopic portion is contracted to the connecting portion, and the connecting portion is rotated to the underside of the wheeled stroller for storage by the rotating shaft. For example, in an embodiment, the connecting portion is also configured to be telescopic. For example, the connecting portion and the telescopic portion are both "rolling door" type structures. Further, the telescopic portion or the connecting portion is extended and extended to Forming a ceiling is also conducive to sheltering from the wind and rain during daily use.

For example, the expansion and contraction portions of the two blocking components abut each other and together form a blocking surface 6133. The blocking assembly further includes a rotary driving member 63, one end of the rotating shaft being coupled to the rotary driving member. In order to facilitate the flattening of the two telescopic portions, the edge of the telescopic portion is provided with a plurality of strip-shaped grooves arranged in parallel, and strip-shaped ribs are formed between two adjacent strip-shaped grooves, and one of the expansion and contraction portions of the blocking assembly The strip groove cooperates with the strip rib of the expansion and contraction portion of the other retaining assembly.

Since the wheeled stroller is provided with two meeting parts, when the vehicle is in use, the four lifting parts can be used to ground the four meeting tires, and the four driving tires are suspended. The four car tires in the middle of the chassis are driven at a slow speed. At this time, the side portion of the vehicle body, that is, the portion of the vehicle body at the driving tire, can be suspended outside the roadbed without side roll, thereby reducing the time of the car. The road width occupied can be carried out without reversing, making the wheeled baby carriage more convenient.

For example, when the vehicle is finished, the lifting member can release the four meeting tires, and the four meeting tires are contracted under the pulling of the holding member and interrupted with the driving shaft and the steering shaft. The connection, at this time, the wheeled stroller can resume normal driving. For example, four reincarnation tires after returning to the original state may be flush with the four service tires to assist in supporting the ground and improving the stability of the wheeled baby carriage. Alternatively, the four meeting tires may be at a position higher than the four driving tires so as not to be in contact with the ground to reduce the friction with the ground, thereby reducing the driving resistance of the wheeled baby carriage.

For example, in order to facilitate the pulling of the four meeting tires, wherein the pulling members comprise four tension springs 65 respectively connected to the four meeting tires, each tension spring comprising a first tensioning section connected in sequence 651 and the second tension section 653 and the third tension section 655, the elastic coefficient of the first tension section and the elastic coefficient of the third tension section are both smaller than the elastic coefficient of the second tension section, and the tension spring The first tension section is coupled to the chassis, and the third tension section of the tension spring is coupled to the corresponding vehicle tire. Since the pulling member includes three tension sections, and the elastic coefficients of the first tension section and the third tension section at both ends are smaller than the elastic coefficient of the second tension section, the vehicle tire can be made better. Buffer.

For example, in order to improve the stability of the vehicle, two parking tires of each vehicle assembly are respectively disposed on both sides of the central axis of the vehicle body and the two vehicle tires are spaced apart from each other. The two meeting assemblies are respectively a front meeting assembly and a rear meeting assembly. The front meeting assembly is disposed at a front portion of the chassis, and the rear meeting assembly is disposed at a rear portion of the chassis. Such a symmetrical arrangement can improve the stability of the vehicle tire during operation, that is, improve the stability of the wheeled bicycle. The first tension section, the second tension section and the third tension section are all spiral. For example, in order to facilitate the connection of the holding member or the lifting member to the vehicle tire, each of the vehicle tires is provided with a tire shaft, and one end of the third tensioning portion is slidably coupled to the tire. On the shaft. A sliding groove portion is recessed on the tire shaft, and one end of the lifting member is rotatably sleeved in the sliding groove portion. The third tensioning force segment and the lifting member are respectively connected to the tire shaft of the vehicle tire by means of arranging, which facilitates the connection without affecting the rotation of the vehicle tire. Since the speed is very slow when the car is in use, it is acceptable even if the above-mentioned socket method has a certain frictional force. For example, a plurality of balls are disposed on the sliding groove portion and coated with lubricating oil. For example, if the plurality of balls are coated with organic oil, the rotation smoothness of the vehicle tire can be improved. For example, the tire shaft is coupled to the vehicle body to support the vehicle body.

The base of the side view light is disposed above the central axis of the corresponding front wheel. Therefore, when the tire rotates, a larger angle of illumination can be performed on the direction of the side of the vehicle body, thereby improving the lighting effect. For example, the side view light further includes a reflective barrel 85 disposed on the base, and the LED bead is disposed in the reflective barrel. The inner surface of the reflective cylinder is coated with a reflective layer 851. The reflecting cylinder has a conical cylindrical shape. The conical cylindrical reflector can appropriately increase the reflection angle of the light of the LED lamp bead to improve the illumination range.
