Example

[0054] See attached Figure 1-3 , a baby stroller seat shock-absorbing structure, including a shock-absorbing component 1 and a hinge 2.

[0055] In this embodiment, the shock absorbing assembly 1 and the hinge 2 are arranged on different sides, that is, they are arranged on the front and rear sides below the seat 100 respectively.

[0056] The rear end of the seat 100 is rotatably connected to the vehicle frame 200 via the hinge 2. The shock-absorbing assembly 1 is disposed on the front side below the seat 100, and its two ends are rotatably connected to the seat 100 and the vehicle frame 200, respectively.

[0057] The frame 200 includes a front bracket 210 and a rear link 220. When the frame 200 is fully deployed and locked, the front bracket 210 and the rear link 220 are fixed relative to the frame 200. The hinge 2 is fixedly connected to the rear link 220. One end of the shock absorber assembly 1 is rotatably connected to the seat 100, and the other end is rotatably connected to the crossbar 211 on the front side of the front bracket 210.

[0058] The number of the shock absorbing components 1 on the lower front side of the seat 100 is set to be at least two, and they are evenly arranged in a straight line, such as Figure 1 The embodiment shown is a scheme in which two shock-absorbing components 1 are provided.

[0059] The shock-absorbing assembly 1 arranged on the opposite side of the hinge 2 is inclined from top to bottom toward the middle of the seat 100 so as to adapt to any state of the seat 100 when the seat 100 rotates around the hinge 2 .

[0060] The usage scenario of the above solution is as follows: when a baby sits on the seat 100, the front end of the entire seat 100 can swing downward around the hinge 2 at the rear end, and the front shock-absorbing component 1 is compressed and rotates forward around the frame 200 to adapt to the rotating seat 100, thereby achieving shock absorption.

[0061] See attached Figure 3 In this embodiment, the shock absorbing assembly 1 includes a central shaft 11, a shock absorbing spring 12 and two limiting members, which are a first limiting member 13 and a second limiting member 14 respectively.

[0062] The shock absorbing spring 12 is sleeved on the outside of the central axis 11, and its two ends respectively abut against the opposite end surfaces of the two limiting members. The first limiting member 13 slides with the central axis 11 to allow the shock absorbing spring 12 to expand and contract.

[0063] The ends of the central axis 11 are rotatably connected to the seat 100 and the frame 200 via two stoppers, respectively. A first stopper 13, rotatably connected to the seat 100, is sleeved onto the exterior of the central axis 11. This first stopper 13 is rotatably connected to the front bracket 210 via a rotating shaft. A waist-shaped hole 131 is defined on the surface of the first stopper 13, into which the central axis 11 slidably engages via a connecting member. A second stopper 14, rotatably connected to the frame 200, is integrally formed with the central axis 11 or fixedly connected to the central axis 11 via a connecting member. This second stopper 14 comprises a sleeve portion that sleeves onto the crossbar 211.

[0064] The connecting piece can be a pin, which is matched with the mounting hole on the central shaft 11.

[0065] The connector can also be an elastic button that cooperates with the mounting hole on the central axis 11 so that the two ends of the central axis 11 are automatically plugged into the mounting holes after being inserted into the two limiters, which is more convenient to use than a pin. The connector is not shown in the figure.

[0066] When the seat 100 is loaded, the seat 100 drives the first limiter 13 to move downward, and the distance between the two limiters is shortened, so that the middle shock-absorbing spring 12 is compressed, absorbing and buffering the external force, buffering the external force brought by the load, thereby achieving a shock-absorbing effect.

[0067] In addition to the above scheme, the front and rear positions of the hinge 2 and the shock absorber assembly 1 can also be interchanged, that is, the front end of the seat 100 is rotatably connected to the frame 200 through the hinge 2, the hinge 2 is fixedly connected to the front bracket 210, and the shock absorber assembly 1 is arranged on the rear side below the seat 100, and one end thereof is rotatably connected to the seat 100, and the other end is rotatably connected to the cross bar 211 on the rear side of the front bracket 210; the shock absorber effect of this scheme is the same as the above scheme, which is not shown in the figure. Example

[0070] The number of the shock absorbing components 1 on the lower rear side of the seat 100 is set to be at least two, and they are evenly arranged in a straight line, such as Figure 4 The embodiment shown is a scheme in which two shock-absorbing components 1 are provided.

[0071] A support member 3 is provided below the seat 100 on a side opposite the shock-absorbing assembly 1. The two ends of the support member 3 are pivotally connected to the seat 100 and the vehicle frame 200, respectively. The pivotal connection may be a hinged connection. Furthermore, the support member 3 is tilted from top to bottom toward the center of the seat 100 to accommodate any position of the seat 100 as it rotates about the hinge 2.

[0072] The support member 3 is provided as at least one. When the support member 3 is provided as one, it needs to be provided in the middle of the lower front side of the seat 100. When the support member 3 is provided as two or more, they are evenly arranged in a straight line on the front side of the lower side of the seat 100. Figure 4 The embodiment shown here is a solution in which two support members 3 are provided.

[0073] The shock-absorbing assembly 1 includes a central shaft 11 , a shock-absorbing spring 12 and two limiting members, which are a third limiting member 15 and a fourth limiting member 16 .
