second chassis

111 and 112 are caused to slide relatively, i.e., the chassis assembly 11 is retracted in the front-rear direction, so that the height of the seat 4 and the distance between the front and

rear wheel assemblies

2 and 3 can be adjusted. In addition, the upper frame 14 is always kept in a horizontal state in the whole process, so that the seat 4 is always kept in a horizontal state and cannot incline.

The stroller further comprises a locking mechanism for locking the position of the chassis assembly 11 so that the seat 4 of the stroller is secured in a certain height position for use.

The locking mechanism includes a locking piece 5 and a lock hole 113a capable of being mated with the locking piece 5. The locking piece 5 is slidably provided on a member of both the first chassis 111 and the second chassis 112 slidably connected to the slide sleeve 113, and in this embodiment, the locking piece 5 is slidably provided in the bottom tube 111a, and the lock hole 113a is provided on the slide sleeve 113.

The locking pieces 5 are provided at intervals along the length extending direction of the bottom pipe 111 a. Each locking piece 5 is provided with a locking portion 511. When the locking mechanism is in the locked state, the locking portion 511 is caught in the locking hole 113a, thereby locking the positions of the bottom tube 111a and the slide sleeve 113 so that the first chassis 111 and the second chassis 112 cannot slide relative to each other, as shown in fig. 6 and 7. When the locking mechanism is in an unlocked state, the locking portion 511 is disengaged from the locking hole 113a, and the sliding sleeve 113 can slide along the bottom tube 111a, so that the first chassis 111 and the second chassis 112 can slide relatively.

In this embodiment, as shown in fig. 6 to 8, the locking member 5 adopts a spring pin, the spring pin includes a lock pin 51 and a spring piece 52, the lock pin 51 is disposed on the spring piece 52, the locking portion 511 is disposed on the lock pin 51, and the locking portion 511 is hemispherical. The bottom tube 111a is provided with a perforation, the elastic sheet 52 is positioned in the lumen of the bottom tube 111a, and the locking pin 51 passes through the perforation on the bottom tube 111a under the action of the elastic force of the elastic sheet 52, so that the locking part 511 protrudes out of the lumen of the bottom tube 111 a.

The locking member 5 is in the form of a spring pin, which is simple in structure and convenient in unlocking operation of the locking mechanism from the locked state, and the locking portion 511 is pushed to be disengaged from the lock hole 113a.

In the process of sliding the first chassis 111 and the second chassis 112 relatively, when the sliding sleeve 113 slides to the position corresponding to the locking hole 113a on the sliding sleeve 113 and the locking part 511 relative to the bottom tube 111a, the locking part 511 is clamped in the locking hole 113a, the locking mechanism is in a locking state, and the seat 4 is fixed at a height position. When the locking pieces 5 at different positions in the front-rear direction are engaged with the locking holes 113a, the seat 4 is at different height positions.

The locking member 5 is provided at least at the front end portion and the rear end portion of the bottom pipe 111a, and the slide bush 113 is fixedly provided at the front end portion of the second chassis 112. When the first chassis 111 and the second chassis 112 are relatively slid so that the locking piece 5 at the front end portion of the bottom tube 111a is engaged with the locking hole 113a, the seat 4 is at the highest position, as shown in fig. 1 and 2, at which time the distance between the front wheel assembly 2 and the rear wheel assembly 3 is minimized. When the first chassis 111 and the second chassis 112 are relatively slid so that the locking piece 5 at the rear end portion of the bottom tube 111a is engaged with the locking hole 113a, the seat 4 is at the lowest position, as shown in fig. 3 to 6, at which time the distance between the front wheel assembly 2 and the rear wheel assembly 3 is maximized.

When the child car needs to move the seat 4 from a high position to a low position, after the locking mechanism is unlocked, the front rod 12 is rotated backwards around the front wheel axle 114, so that the upper frame 14 drives the seat 4 to move downwards, the connecting rod 15 is moved backwards, the rear stay 13 is rotated forwards around the rear wheel axle 115, the second underframe 112 drives the sliding sleeve 113 to slide backwards relative to the first underframe 111, the distance between the front wheel assembly 2 and the rear wheel assembly 3 is increased, and the sliding sleeve 113 slides until the positions of the locking part 511 and the locking hole 113a correspond, so that the locking mechanism is locked again.

When the child car needs to move the seat 4 from a low position to a high position, the operation is reversed.

The buggy further comprises a gearbox 6 for driving the buggy to travel, the front wheel assembly 2 and the rear wheel assembly 3 being arranged on the left and right sides of the frame, respectively. The gear box 6 can be respectively connected with the front wheel assemblies 2 on the left side and the right side to drive the front wheel assemblies 2 to rotate, namely the front wheel assemblies 2 are driving wheels, and the rear wheel assemblies 3 are driven wheels. Alternatively, the gear box 6 may be connected to the rear wheel assemblies 3 on the left and right sides respectively to drive the rear wheel assemblies 3 to rotate, that is, the rear wheel assemblies 3 are driving wheels, and the front wheel assemblies 2 are driven wheels. Of course, the front wheel assemblies 2 on the left and right sides and the rear wheel assemblies 3 on the left and right sides may be connected to the gear case 6, respectively.

In this embodiment, the gear boxes 6 may be connected to the front wheel assemblies 2 on the left and right sides, respectively, so that the output rotation speeds of the gear boxes 6 on the left and right sides are the same when the stroller is traveling straight. When the child car needs to turn, the output rotation speeds of the gear boxes 6 on the left and right sides are different, so that the front wheel assemblies 2 on the left and right sides form a differential speed, and the child car can turn.

The buggy further comprises a steering wheel 7 for controlling the steering of the buggy, the steering wheel 7 being located in front of the seat 4, the steering wheel 7 being rotatably arranged at the upper end of the front bar 12.
