Detailed ways

The technical solution of the present utility model will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 6, the double child stroller of the present invention includes a stroller frame 1 in unfolded and folded states, a front wheel assembly 2 arranged at the bottom front of the stroller frame 1, a front wheel assembly 2 arranged at the push The rear wheel assembly 3 at the bottom rear portion of the cart frame 1 and the locking mechanism for locking the stroller frame 1 in the unfolded state.

The stroller frame 1 includes a front support 11, a rear support 12, a side armrest 13, an upper push rod 14, a lower push rod 15, a first seat post 16, a second seat post 17, a first connecting rod 18 and a second connecting rod 19. When the stroller is in the unfolded state, the front bracket 11, the upper push rod 14, the lower push rod 15 and the first connecting rod 18 all extend obliquely upward from the front to the rear, the rear bracket 12 extends obliquely from the front to the rear, and the side armrests 13 , the first seat post 16 and the second seat post 17 both extend in the front-rear direction. The front bracket 11 is used to install the front wheel assembly 2; the rear bracket 12 is used to install the rear wheel assembly 3; The upper part is rotatably connected; the upper part of the lower push rod 15 is rotatably connected with the lower part of the upper push rod 14, and the lower part of the lower push rod 15 is at least rotatably connected with one of the two parts of the rear bracket 12 and the side armrest 13; the first The connecting rod 18 is respectively rotatably connected with the bottom of the upper push rod 14 and the rear bracket 12; the first seat post 16 is respectively rotatably connected with the lower push rod 15 and the first connecting rod 18; the second seat post 17 is respectively connected with the front support 11 It is rotatably connected with the first connecting rod 18; one end of the second connecting rod 19 is at least rotatably connected with one of the two parts of the side armrest 13 and the rear bracket 12, and the other end of the second connecting rod 19 is connected with the second The seat post 17 is rotatably connected.

In this embodiment, the lower part of the lower push rod 15 is rotationally connected to the upper part of the rear bracket 12, and one end of the second connecting rod 19, the rear end of the side armrest 13, and the upper part of the rear bracket 12 are rotationally connected to each other. . In this way, a four-bar linkage mechanism is formed between the front bracket 11, the side armrest 13, the second link 19 and the second seat post 17, and the rear support 12, the first link 18, the second seat post 17 and the second A four-bar linkage is also formed between the connecting rods 19, and a four-bar linkage is also formed between the upper push rod 14, the lower push rod 15, the first seat post 16 and the first connecting rod 18. Simultaneously, a quadrilateral structure is formed between the front support 11, the side armrest 13, the second link 19 and the second seat post 17, and the rear support 12, the first link 18, the second seat post 17 and the second link 19 A quadrilateral structure is formed between them, and a quadrilateral structure is formed between the upper push rod 14 , the lower push rod 15 , the first seat post 16 and the first connecting rod 18 .

The first seat post 16 and the first connecting rod 18 are rotatably connected by a sliding piece 10, the sliding piece 10 is rotatably connected with the first connecting rod 18, and the first seat post 16 is slidably arranged on the sliding piece 10, so that , when the stroller is folded, while the first seat post 16 and the first connecting rod 18 rotate relative to each other, the first seat post 16 also slides relative to the slider 10, which can make the lower push rod 15 and the first connecting rod 18 can be closer together, so that the folded child stroller has a more compact structure and a smaller volume. In this embodiment, the sliding member 10 adopts a sliding sleeve, and the sliding sleeve is sheathed on the first seat post 16 .

A specific embodiment, the rear bracket 12 includes a rear support rod 121 extending obliquely downward from the front to the rear and a connecting piece 122 with one end fixedly connected to the upper end of the rear supporting rod 121. In this embodiment, the connecting piece 122 Extending backward from the connection with the rear support rod 121, the lower part of the lower push rod 15 is rotatably connected with the other end of the connecting piece 122, the rear end of the side armrest 13, the upper end of the rear support rod 122 and the second connection Three parts at one end of the rod 19 are connected in rotation with the same axis.

The locking mechanism can be arranged on the front bracket 11, the rear bracket 12, the side armrest 13, the upper push rod 14, the lower push rod 15, the first seat post 16, the second seat post 17, the first connecting rod 18, and the second connecting rod 19 Between two parts that are rotationally or slidably connected with any of the sliders 10. In this embodiment, the locking mechanism is arranged at the rotational connection between the upper push rod 14 and the first connecting rod 18 . The details of the locking mechanism are not the technical points to be protected by this patent, and the structures in the prior art can be adopted.

When the double stroller is in the unfolded state, the locking mechanism is in the locked state, the second seat post 17 is located in front of the first seat post 16, and the first seat post 16 is located above the second seat post 17, as shown in Figure 1 and Fig. 2.

When the double stroller needs to be folded, the locking mechanism is unlocked first, and then the upper push rod 14 is pressed down to drive the lower push rod 15 to turn down and close to the rear bracket 12. In this process, due to the first connecting rod 18 and the second The function of the seatpost 17 makes the front bracket 11 turn forward at a certain angle, and when the lower push rod 15 continues to turn downward, the second connecting rod 19 pulls the second seatpost 17 to move backward, so that the front bracket 11 turns backward gradually. Close to the rear bracket 12; when the lower push rod 15 is turned down, the first seat post 16 is rotated, and the first seat post 16 is also sliding relative to the slider 10, so that the lower push rod 15, the first connecting rod 18 and The rear bracket 12 is moved closer together until the rods forming the stroller frame 1 are closed together, and finally folded as shown in Figure 6. The folded double stroller is compact in structure, small in size, and easy to carry and store .

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to enable those familiar with this technology to understand the content of the present utility model and implement it accordingly, and not to limit the protection scope of the present utility model. All equivalent changes or modifications made according to the spirit of the utility model shall fall within the protection scope of the utility model.
