The cabs of heavy truck type on the market at present are mainly divided into a flat head cab and a long head cab, and the wedge-shaped cab is a cab form between the flat head cab and the long head cab. The width of the front end of the wedge-shaped cab is narrowed, and the wedge-shaped cab has great advantages in the aspect of appearance modeling and wind resistance reduction.

Typically, in the flat-head and long-head cabs, the steering column and its vias are arranged outside the cab floor stringers. However, due to the narrowed width of the wedge-shaped cab front wall, such an arrangement may cause interference between the steering column and the stringers of the cab floor.

In view of this, the present invention proposes a cab floor assembly for a wedge-shaped cab.

Referring to fig. 1 to 3, in an embodiment of the present invention, the cab floor assembly includes a floor main body 100 and a floor frame 200. Wherein the floor main body 100 has a front end 110 toward the front of the vehicle and a rear end 120 toward the rear of the vehicle, the floor main body 100 being provided with a through hole 130 near the front end 110, the through hole 130 being for passing a steering column of the vehicle. Specifically, the through hole 130 is for passing a steering column of a vehicle therethrough, so that the steering column connects a vehicle steering system located below the floor main body 100 with a steering wheel located above the floor main body 100, thereby achieving an operation of controlling the steering wheel to control steering of the vehicle. In an embodiment, two through holes 130 are formed in the floor main body 100, and the two through holes 130 are respectively located at the left side and the right side of the floor main body 100, which is close to the front end 110, so that two situations of right steering wheel arrangement and left steering wheel arrangement are satisfied, and the cab floor assembly can be applied to a vehicle model with left steering wheel and a vehicle model with right steering wheel arrangement, and the application range of the cab floor assembly is wider. Of course, only one through hole 130 may be provided in the floor main body 100, and the through hole 130 may be located at the left side or the right side of the floor main body 100, so as to meet the vehicle type with the left steering wheel or the right steering wheel. Here, the number of the through holes 130 is not limited.

The floor frame 200 is fixed to the floor main body 100, and the floor frame 200 has a first end facing the front end 110 and a second end facing the rear end 120, the first end having a width smaller than that of the second end. Specifically, the floor frame 200 is fixed to the floor main body 100 to provide structural strength to the cab floor assembly, and to enhance the stress of the cab floor assembly, thereby enhancing the safety protection of personnel inside the cab. The first width of the floor frame 200 is smaller than the second width to fit the floor body 100 of the wedge-shaped cab.

The floor frame 200 includes a first longitudinal beam 211, a second longitudinal beam 212, and a cross beam. The first longitudinal beam 211 and the second longitudinal beam 212 are symmetrically arranged, and the first longitudinal beam 211 and the second longitudinal beam 212 extend along the length direction of the floor main body 100 and are obliquely arranged near the front end 110 so as to avoid the through hole 130. Specifically, the first side member 211 and the second side member 212 are mainly used to receive forces in the front-rear direction to which the vehicle is subjected. Since the first width of the floor frame 200 is smaller than the second width, if the first longitudinal beam 211 and the second longitudinal beam 212 extend linearly along the length direction of the floor main body 100, the first longitudinal beam 211 and/or the second longitudinal beam 212 will interfere with the steering column of the vehicle, and in this case, in order to connect the steering column with the steering wheel through the cab floor assembly, the through hole 130 needs to be opened on the first longitudinal beam 211 and/or the second longitudinal beam 212. However, the through holes 130 are formed on the first longitudinal beam 211 and/or the second longitudinal beam 212, which reduces the structural strength of the first longitudinal beam 211 and/or the second longitudinal beam 212, and the edges of the through holes 130 are easy to generate stress concentration during the running process of the vehicle, so that the first longitudinal beam 211 and/or the second longitudinal beam 212 are cracked, thereby affecting the structural strength of the cab floor assembly and generating potential safety hazards. In the present invention, the first and

second stringers

211, 212 are inclined near the front end 110 to avoid the through-hole 130, so that the steering column is connected to the steering wheel through the through-hole 130. In this way, the through holes 130 are avoided from being formed in the first longitudinal beam 211 and/or the second longitudinal beam 212, so that the structural strength of the first longitudinal beam 211 and/or the second longitudinal beam 212 is prevented from being reduced, and the structural strength of the cab floor assembly is ensured.

The cross member is located between the front end 110 and the rear end 120 and is fixedly connected to the first longitudinal member 211 and the second longitudinal member 212. Specifically, the cross member is mainly used to receive forces in the left-right direction to which the vehicle is subjected. Specifically, in one embodiment, the cross member is disposed parallel to the width direction of the floor main body 100, so that the cross member can withstand more force from the left and right directions of the vehicle, and the lateral force resistance of the cab floor assembly is enhanced. The cross members are parallel to the width direction of the floor main body 100, that is, the cross members extend in the width direction of the floor main body 100, and intersect and are fixed with the first and

second stringers

211, 212 extending in the length direction of the floor main body 100. More specifically, the floor frame 200 adopts a sheet metal structure, that is, the cross beam, the first longitudinal beam 211 and the second longitudinal beam 212 adopt a sheet metal structure, and are welded and fixed, so that the sheet metal structure ensures the structural strength of the floor frame 200, and the welded and fixed connection stability and firmness of the floor frame 200 are ensured.

In one embodiment of the present invention, the first and

second stringers

211, 212 extending in the longitudinal direction of the floor body 100 and the cross members extending in the width direction of the floor body 100 are provided in the floor frame 200, so that a stable floor frame 200 structure is formed among the first and

second stringers

211, 212 and the cross members. The stable floor frame 200 structure ensures the structural strength of the cab floor assembly by fixing the floor frame 200 to the floor main body 100 to form the cab floor assembly, thereby enhancing the tolerance of the cab to the front and rear directions and the left and right directions of the vehicle and further enhancing the safety protection of personnel inside the cab. Meanwhile, the first longitudinal beam 211 and the second longitudinal beam 212 are obliquely arranged in the direction towards the front end 110 of the floor main body 100 so as to avoid the through hole 130 for the steering column to pass through, compared with the arrangement that the through hole 130 is formed in the first longitudinal beam 211 and/or the second longitudinal beam 212 in the prior art, the invention avoids the reduction of the structural strength of the first longitudinal beam 211 and/or the second longitudinal beam 212 caused by the formation of the through hole 130, and also avoids the cracking of the first longitudinal beam 211 and/or the second longitudinal beam 212 caused by the stress concentration at the edge of the through hole 130 in the running process of a vehicle, thereby ensuring the structural strength of the first longitudinal beam 211 and/or the second longitudinal beam 212, further ensuring the structural strength of the floor skeleton 200 and the cab floor assembly, and ensuring the safety protection of personnel in a cab.

Further, in an embodiment, the first longitudinal beam 211 and the second longitudinal beam 212 are disposed obliquely toward a direction away from each other on a side closer to the front end 110 such that the through hole 130 is located between the first longitudinal beam 211 and the second longitudinal beam 212. Specifically, the first and

second stringers

211, 212 are inclined toward the outside of the cab floor assembly on the side near the front end 110, that is, the width between the first and

second stringers

211, 212 is set to become larger in the direction from the rear end 120 toward the front end 110, so that the through-hole 130 is relieved between the first and

second stringers

211, 212. In this way, the first longitudinal beam 211 and the second longitudinal beam 212 are obliquely arranged towards the side close to the front end 110 and far away from each other, so that the through hole 130 for the steering column to pass through is avoided on the one hand, the steering column is connected with the steering wheel through the through hole 130, the through hole 130 is prevented from being formed in the first longitudinal beam 211 and/or the second longitudinal beam 212, the structural strength of the first longitudinal beam 211 and/or the second longitudinal beam 212 is prevented from being reduced, and the cracking of the first longitudinal beam 211 and/or the second longitudinal beam 212 caused by stress concentration generated at the edge of the through hole 130 in the running process of the vehicle is prevented. On the other hand, the first longitudinal beam 211 and the second longitudinal beam 212 are inclined towards and away from each other on the side close to the front end 110, so that the first longitudinal beam 211 and the second longitudinal beam 212 have a sufficient distance space on the side close to the front end 110, and the engine radiator 300 of the vehicle is mounted at the lower position between the first longitudinal beam 211 and the second longitudinal beam 212, so that a layout space is provided for mounting and fixing the engine radiator 300, and interference between the cab floor assembly and the engine radiator 300 when the cab jolts up and down during running of the vehicle is avoided.

Further, in an embodiment, the first longitudinal beam 211 and the second longitudinal beam 212 are disposed obliquely toward a direction approaching each other on a side approaching the front end 110 such that the through hole 130 is located outside the first longitudinal beam 211 and/or the second longitudinal beam 212. Specifically, the first and

second stringers

211, 212 are inclined toward the interior of the cab floor assembly on a side near the front end 110, i.e., the width between the first and

second stringers

211, 212 is tapered in a direction from the rear end 120 toward the front end 110, thereby avoiding the through-holes 130 outside the first and/or

second stringers

211, 212. In this way, the first longitudinal beam 211 and the second longitudinal beam 212 are obliquely arranged towards each other at the side close to the front end 110, so that the through hole 130 for the steering column to pass through is avoided on one hand, the steering column is connected with the steering wheel through the through hole 130, the through hole 130 is prevented from being formed in the first longitudinal beam 211 and/or the second longitudinal beam 212, the structural strength of the first longitudinal beam 211 and/or the second longitudinal beam 212 is prevented from being reduced, and the cracking of the first longitudinal beam 211 and/or the second longitudinal beam 212 caused by stress concentration generated at the edge of the through hole 130 in the running process of the vehicle is prevented. In this embodiment, the heights of the first and

second stringers

211, 212 are generally 80-100mm, so that the engine radiator 300 fixed to the lower portion of the cab floor assembly does not interfere with the first and

second stringers

211, 212, that is, a sufficient installation fixing space is provided for the engine radiator 300, that is, the heights of the first and

second stringers

211, 212 can be reduced according to the specific situation of the vehicle even if the distance between the engine radiator 300 and the first and

second stringers

211, 212 is increased, so that a sufficient buffer space is provided between the engine radiator 300 and the first and

second stringers

211, 212 when the cab bumps up and down during the running of the vehicle, so that the cab floor assembly does not interfere with the engine radiator 300. Of course, the overall installation height of the cab may be directly raised, so that the distance between the engine radiator 300 and the first and

second stringers

211, 212 is increased, and interference between the engine radiator 300 and the first and

second stringers

211, 212 is avoided.

Further, in order to improve the tolerance of the cab floor assembly to external forces in the fore-and-aft direction of the vehicle, the floor frame 200 further includes a third longitudinal beam 213 positioned between the first longitudinal beam 211 and the second longitudinal beam 212, the third longitudinal beam 213 extending along the length direction of the floor body 100. Specifically, in an embodiment, the third longitudinal beam 213 is located in the middle of the first longitudinal beam 211 and the second longitudinal beam 212, and the first longitudinal beam 211 and the second longitudinal beam 212 are symmetrically disposed with the third longitudinal beam 213 as a symmetry center, so that the stress intensity on the left and right sides of the cab floor assembly is consistent, which is beneficial to the uniformity of the overall stress of the cab floor assembly. The arrangement of the third longitudinal beam 213 enhances the tolerance of the cab to external forces in the front-rear direction of the vehicle and improves the structural strength of the cab floor assembly.

Further, in order to improve the tolerance of the cab floor assembly to external forces in the left-right direction of the vehicle, the cross members include a first cross member 221 and a second cross member 222 that are disposed at intervals along the longitudinal direction of the floor main body 100, and the first cross member 221 and the second cross member 222 are connected and fixed to the first longitudinal member 211, the second longitudinal member 212, and the third longitudinal member 213. Specifically, the first beam 221 is disposed proximate the front end 110 of the floor body 100, and the second beam 222 is disposed proximate the rear end 120 of the floor body 100. The first beam 221 and the second beam 222 each extend in the width direction of the floor body 100 and intersect and are fixed to the first, second, and

third stringers
