[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Referring to the figures shown, this embodiment provides a middle row seat mounting structure for mounting a quarter seat 3 and a six - seat position seat 4, including a floor system 5 and a rear longitudinal beam system 7, and further including a middle floor mounting cross beam 2, a rear floor mounting cross beam 6, and a seat strengthening cross beam 8. The seat strengthening cross beam 8 is located in front of the middle floor mounting cross beam;

[0023] The floor system is compatible with fuel - powered and hybrid - powered vehicle models. Compatibility means that the fixed installation of the battery pack does not require adjustment of the main structure of the middle and rear floors, and universality can be achieved by adding the form of mounting brackets.

[0024] The seat reinforcement crossbeam 8 is provided with seat bracket mounting holes 81, 82, 83 and seat belt fixing points 84. The seat brackets include a six-position seat mounting left bracket 31, a six-position seat mounting middle bracket 32 and a four-position seat mounting bracket 41. It also includes a reinforcing plate which is located between the middle floor mounting crossbeam 2 and the rear floor mounting crossbeam 6. The seat bracket mounting holes 81, 82, 83 are mounting holes with a diameter of φ = 8 mm for threaded connection with the seat brackets. The seat brackets are provided with main positioning holes and bolt mounting holes. At least one reinforced rear longitudinal beam is provided in the middle section of the middle floor mounting crossbeam 2. It also includes a reinforcing member which includes a reinforcing plate arranged on the reinforced rear longitudinal beam. The reinforcing plate is arranged between the reinforced rear longitudinal beam and the seat assembly and is fixedly connected to the seat assembly by screwing.

[0025] For the design function definition of the vehicle seat structure, under the goal of ensuring the welding, installation and use requirements of other structures carried by the floor assembly and the middle row seat installation structure, in the floor assembly and the middle row seat installation structure such as Figure 3 , Figure 4 The installation and fixing structure in the system improves the versatility of the floor system and ensures the rigidity and strength performance of the seat structure.
