The front end of the main driver seat is connected to the left two mounting sleeves 2 on the front seat cross beam through fasteners, the rear end is connected to the left two mounting sleeves 2 on the rear seat cross beam through fasteners, the front end of the co-driver seat is connected to the right two mounting sleeves 2 on the front seat cross beam through fasteners, and the rear end is connected to the right two mounting sleeves 2 on the rear seat cross beam through fasteners.

[0074] The utility model also proposes a vehicle with the above-mentioned vehicle seat 100.

[0075] As shown in the accompanying drawings Figure 1 and Figure 2 According to the vehicle of the utility model embodiment, the vehicle comprises a floor and the above-mentioned vehicle seat 100.

[0076] Specifically, the floor is an important component of the vehicle body bottom structure, and bears the task of bearing the weight and load of the vehicle body. It can evenly distribute the weight of the vehicle body and the load during driving to other parts of the vehicle body, ensuring the stability and safety of the vehicle. Further, the vehicle seat 100 is arranged on the floor, and the floor can provide support for the vehicle seat 100 to ensure normal installation of the vehicle seat 100.

[0077] According to the vehicle of the utility model embodiment, by arranging the above-mentioned vehicle seat 100, the mounting sleeve 2 comprises a first layer 21, a second layer 22 and an energy-absorbing member 23, the energy-absorbing member 23 is arranged between the first layer 21 and the second layer 22, and the energy-absorbing member 23 is connected with the first layer 21 and the second layer 22. The energy-absorbing member 23 can be used to absorb the vibration transmitted from the first layer 21 to the second layer 22, reduce the transmission of vibration, and achieve the vibration reduction effect of the mounted part. When the mounting sleeve 2 is used in the vehicle for mounting the seat, in the case of impact of the vehicle, the energy-absorbing member 23 can absorb the vibration transmitted from the first layer 21 to the second layer 22 as much as possible, avoid the vibration of the vehicle body being transmitted to the seat through the mounting sleeve 2, thereby achieving the vibration reduction effect of the seat, improving the collision safety performance, improving the driving comfort of the user, and improving the NVH performance of the vehicle.

[0078] Other configurations and operations of the mounting structure 20, the vehicle seat 100, and the vehicle are known to those skilled in the art, and thus will not be described in detail here.
