TECHNICAL FIELD

[0001] The utility model relates to a trolley technical field, concretely relates to a trolley seat rod linkage mechanism. BACKGROUND

[0002] Trolleys, such as baby strollers, are widely used as a convenient means of transport. For trolleys, efficient storage and convenient use are always the core points of user attention.

[0003] In the design of conventional trolleys, the support (usually including front support and rear support) is the basic support structure of the trolley, and some trolleys are provided with a seat rod. The seat rod has various purposes, such as being used to support babies in cooperation with other structures.

[0004] At present, the seat rod and the support are generally arranged independently, which is beneficial to separate operation (such as separate maintenance) of the two, but is not conducive to the use of the trolley in daily life. Based on the above-mentioned independent arrangement, the seat rod and the support need to be stored separately when the trolley is stored, which results in a large amount of work and a long time required for storing the trolley, affecting the user experience.

[0005] Therefore, how to solve the above-mentioned problems of the prior art has become the subject to be studied and solved by the utility model. CONTENT OF THE UTILITY MODEL

[0006] The utility model aims to provide a trolley seat rod linkage mechanism.

[0007] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of:

[0008] A trolley seat rod linkage mechanism, comprising a seat rod, a front support and a linkage assembly;

[0009] Among them, the seat rod and the front support are rotatably arranged relative to each other;

[0010] The linkage assembly comprises:

[0011] A first rotating rod rotatably arranged on the seat rod;

[0012] A second rotating rod rotatably connected with the front support and the first rotating rod, respectively.

[0013] In the above-mentioned scheme, when the trolley is stored, the front support is rotated, and the front support promotes the rotation of the seat rod through the first rotating rod and the second rotating rod in the linkage assembly, avoiding the need to rotate and store the seat rod separately, reducing the work amount and the time required for storing the trolley, and thus improving the user experience.

[0014] It should be noted that the seat rod, the front support and the rear support described below are the existing structures in the stroller, and the present application does not limit the specific shape of the three. Taking the front support as an example, the front support can be regarded as a support assembly, which is not limited to only including a single support structure.

[0015] It should also be noted that the manner in which the seat rod and the front support are rotatably arranged with each other is not limited herein, such as by means of a rotating shaft.

[0016] Further technical solutions, the stroller has a storage state:

[0017] In the storage state, the front support is rotatably arranged, and the front support drives the seat rod to rotate and store through the second rotating rod and the first rotating rod.

[0018] The present embodiment clearly defines the stroller storage process, specifically, the linkage process of the front support and the seat rod, avoiding the need to separately rotate and store the seat rod, reducing the amount of work and time required to store the stroller, thereby improving the user experience.

[0019] Further technical solutions, the first rotating rod has a first connecting end and a second connecting end along the length direction of the first rotating rod, the first connecting end is rotatably arranged on the seat rod, and the second connecting end is rotatably arranged on the second rotating rod.

[0020] The present embodiment clearly defines the specific structure of the first rotating rod, and also defines the connection positions of the first rotating rod, the seat rod and the second rotating rod.

[0021] The first rotating rod is actually rotatably connected to the seat rod and the second rotating rod at both ends along the length direction of the first rotating rod. Compared with connecting the first rotating rod by other parts, such arrangement can reduce the occupied space of the first rotating rod, and also facilitates the first rotating rod to be designed as a regular structure to reduce the processing difficulty, such as the first rotating rod can be a square rod.

[0022] Further technical solutions, further comprising a rear support, the rear support, the seat rod and the front support are rotatably arranged with each other.

[0023] The manner in which the rear support, the seat rod and the front support are rotatably arranged with each other is not limited herein, such as by means of a rotating shaft.

[0024] The introduction of the rear support can improve the stability of the stroller and improve the application scope of the present application.

[0025] Further technical solutions, the linkage assembly further comprises a third rotating rod, the third rotating rod is rotatably connected with the rear support and the second rotating rod, respectively.

[0026] When the stroller is stored, the rear support is rotated, the rear support drives the front support to rotate and be stored through the third rotating rod and the second rotating rod, and the front support drives the seat rod to rotate and be stored through the second rotating rod and the first rotating rod.

[0027] Due to the arrangement of the third rotating rod, even if the rear support is arranged, the stroller storage time and the storage workload can be greatly reduced, and the user experience is ensured.
