Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a rear connecting rod structure for improving the mode of an automobile seat. Background Art

[0002] Car seat comfort has always been an important factor in car design, but the vibration generated during the driving of the car will affect the comfort of the car seat.

[0003] As one of the important indicators for evaluating seat comfort, seat vibration transmissibility plays a vital role in seat design and optimization. Existing car seats use spring shock-absorbing structures to cushion the vibrations generated during the driving process.

[0004] At the same time, the vibration input signals of the existing seat system mainly come from the engine and the uneven road surface, but the input signals of the seat system usually cannot be modified, which makes it easy for the seat and the car body to resonate, affecting the seat comfort. Utility Model Content

[0005] The purpose of the utility model is to provide a rear link structure for improving the mode of a car seat, aiming to solve the problem that the vibration input signal of the seat system mainly comes from the engine and the uneven road surface, while the input signal of the seat system usually cannot be modified, which makes it easy for the seat and the car body to resonate and affect the comfort of the seat.

[0006] To achieve the above-mentioned purpose, the utility model provides a rear connecting rod structure for improving the modality of a car seat, including a rear connecting rod, a rear cross tube and a rear connecting rod supporting flange, the rear cross tube being fixedly connected to the rear connecting rod and being located on one side of the rear connecting rod, the rear connecting rod supporting flange being fixedly connected to the rear connecting rod and the rear cross tube respectively, and the rear connecting rod is located on the side of the rear connecting rod close to the rear cross tube.

[0007] Wherein, the front end of the rear connecting rod support flange is integrally connected and fixed to the rear connecting rod.

[0008] Wherein, the inner side wall of the rear connecting rod support flange end is welded to the rear cross tube.

[0009] Wherein, a triangular support is formed between the rear cross tube, the rear connecting rod and the rear connecting rod supporting flange.

[0010] The utility model discloses a rear connecting rod structure for improving the modality of a car seat, wherein an integrally formed rear connecting rod support flange is added to the upper end of the connection end between the rear connecting rod and the rear cross tube, the front end of the rear connecting rod support flange is integrally connected to the rear connecting rod, the rear end inner side of the rear end of the rear connecting rod support flange is overlapped to the rear cross tube and welded to the rear cross tube, at this time, the rear cross tube and the rear connecting rod form a triangular support, thereby improving the modal frequency of the seat, thereby staggering the modal frequency and the excitation frequency of the engine or the pothole road surface, avoiding the occurrence of resonance, and also strengthening the connection strength between the rear connecting rod and the skeleton, thereby improving the subjective feeling and riding comfort of the passengers.

[0015] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0016] The first embodiment of the present application is:

[0017] See also Figure 1 and Figure 2 ,in Figure 1 It is a structural schematic diagram of a rear connecting rod structure for improving the mode of a car seat according to a first embodiment of the utility model. Figure 2 It is a structural schematic diagram of the filling body of the first embodiment of the utility model.

[0018] The utility model provides a rear connecting rod structure for improving the mode of a car seat, comprising a rear connecting rod 101, a rear transverse tube 102 and a rear connecting rod support flange 103. The above solution solves the problem that the vibration input signal of the seat system mainly comes from the engine and the uneven road surface, and the input signal of the seat system is usually not modifiable, which makes it easy for the seat and the car body to resonate, affecting the seat comfort. It can be understood that the above solution can be used to avoid resonance and improve the seat comfort.
