Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

As shown in fig. 1-2, the present embodiment provides a double stroller, comprising a frame 1, wherein the frame 1 is provided with a handlebar, a front wheel 21, a first seat, a first pedal device 51, a second seat, a second pedal device 52 and a rear wheel 22; auxiliary wheels capable of supporting the double baby carriage are arranged on the left side and the right side of the frame 1; the first saddle corresponds to the position of the first pedal means 51 and the second saddle corresponds to the position of the second pedal means 52; the handle bar is connected with the front wheel 21 and can drive the front wheel 21 to rotate so as to change the motion direction of the double baby carriage. In this embodiment, the first seat is a seat near the front wheel, and the second seat is a seat near the rear wheel.

The first pedal device 51 and the second pedal device 52 can be connected to the rear wheel 22 via a transmission device, and can rotate the rear wheel 22 to move the stroller.

In this embodiment, the transmission device includes a first chain wheel 41, a second chain wheel 42, and a chain 44; the first pedal device 51 is connected with the first chain wheel 41 and can drive the first chain wheel 41 to rotate; the first chain wheel 41 is connected with the second chain wheel 42 through a chain 44 and can drive the second chain wheel 42 to rotate, and the second chain wheel 42 is connected with the rear wheel 22 and can drive the rear wheel 22 to rotate. In order to increase the transmission ratio, the diameter of the first chain wheel 41 is larger than that of the second chain wheel 42, so that the first pedal device 51 drives the first chain wheel 41 to rotate for a circle, and can drive the second chain wheel 42 to rotate for multiple circles, thereby driving the rear wheel 22 to rotate for multiple circles, and saving more labor. The connection mode of the first crankset 41 and the first pedal device 51 and the frame 1 can be selected from the installation modes of the existing bicycle.

Meanwhile, the second pedal device 52 is connected to the second crankset 42 and can drive the second crankset 42 to rotate. Specifically, the central axes of second crankset 42 and rear wheel 22 are aligned with the central axis of second pedal means 52.

As an alternative embodiment, the second pedal device 52 includes a central shaft and pedal portions 521 disposed at two ends of the central shaft, and the pedal portions 521 can be detachably connected to the central shaft, specifically, by a threaded connection, or other existing connection means; meanwhile, the second chain wheel 42 and the rear wheel are fixedly connected with the central shaft or connected through a pin key structure, and can rotate simultaneously and can be detached.

For the convenience of installation, a shaft sleeve 522 is further arranged on the central shaft, and the auxiliary wheel is connected with the shaft sleeve 522. The frame 1 includes a second seat support 11, the second seat support 11 can support a second seat, and the second seat support 11 is detachably connected to the shaft sleeve 522, and the specific connection mode can be selected from existing detachable connection modes such as bolt 32 connection, sleeve connection and the like. By providing the bushing 522, the bushing 522 can be kept stationary during rotation of the center shaft, the rear wheel 22, and the second crankset 42, thereby keeping the second seat support 11 and the auxiliary wheel stationary.

Since the footrest 521 and the second seat support 11 are detachably connected, when two persons are not required to ride simultaneously, the footrest 521, the second seat support 11 and the second seat can be detached, and the double stroller can be transformed into a common single stroller. The structure and the function of the baby carriage can be changed according to the needs, and the use is more convenient.

In order to adjust the ground clearance of the auxiliary wheel conveniently, the auxiliary wheel comprises a connecting rod 31 and a rotating wheel 3, the connecting rod 31 comprises two parts which are hinged with each other, the two parts can be connected through a bolt 32, when the ground clearance of the rotating wheel 3 needs to be adjusted, the bolt 32 only needs to be unscrewed, and then the included angle between the two connecting rods 31 is adjusted, so that the ground clearance of the rotating wheel 3 can be changed; as shown in fig. 2, the included angle between the two connecting rods 31 is 90 degrees, and at this time, the two rollers and the rear wheel 22 land at the same time, so that when a child grasps a certain riding skill and may not need an auxiliary wheel, the included angle between the connecting rods 31 can be reduced, and the rotating wheel 3 can be lifted; therefore, the riding skill of the child can be tested without detaching the auxiliary wheel, if the child is found not to be able to independently ride the baby carriage lacking the auxiliary wheel, the rotating wheel 3 can be adjusted to the grounding state, and when the child can be ridden skillfully, the auxiliary wheel can be detached again.

In order to improve the stability and comfort of the child sitting on the vehicle seat, the first vehicle seat and the second vehicle seat are both provided with backrest parts, and meanwhile, the backrest parts on the first vehicle seat can provide a hand holding place for the child sitting behind.

Example 2

As shown in fig. 3, the present embodiment is different from embodiment 1 in that; the transmission device comprises a first chain wheel 41, a second chain wheel 42, a third chain wheel 43 and a chain 44, wherein the first pedal device 51 is connected with the first chain wheel 41 and can drive the first chain wheel 41 to rotate; the first chain wheel 41 is connected with a third chain wheel 43 through a chain 44 and can drive the third chain wheel 43 to rotate; the second pedal device 52 is connected with the third dental disc 43 and can drive the third dental disc 43 to rotate; the third chain wheel 43 is connected with the second chain wheel 42 through a chain 44 and can drive the second chain wheel 42 to rotate; second crankset 42 is coupled to rear wheel 22 and is capable of rotating rear wheel 22. The third chain wheel 43 is a double-layer chain wheel structure and comprises a large chain wheel and a small chain wheel which are coaxially and fixedly connected, wherein the first chain wheel 41 is connected with the small chain wheel through a chain 44, and the large chain wheel is connected with the second chain wheel 42 through the chain 44; through setting up third dental disc 43, can improve the efficiency of riding through twice drive ratio.

The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, and all should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
