Based on the above overall description, as shown in fig. 1 and 2, in the present embodiment, a connection structure between the vehicle frame 1 and the vehicle body 2 in which the left side of the front portion of the vehicle body is suspended, that is, the position indicated by the letter a in fig. 1 will be specifically described as an example. The connection structure between the frame 1 and the vehicle body 2 in the front right-side suspension connection region of the vehicle body and in other regions is similar to that in the front left-side suspension connection region of the vehicle body, so that the following description of the connection structure in the front left-side suspension connection region of the vehicle body can be seen.
Specifically, as one of the implementation forms, as shown in fig. 3, the suspension mounting portion of the present embodiment includes a suspension mounting plate 4 and a suspension reinforcing plate 5, one sides of the suspension mounting plate 4 and the suspension reinforcing plate 5 are fixedly connected to the frame rail 3, the other sides of the suspension mounting plate 4 and the suspension reinforcing plate 5 are fixedly connected together, and the suspension mounting cavity 19 is formed among the suspension mounting plate 4, the suspension reinforcing plate 5 and the frame rail 3.
Further, as a preferred embodiment, the vehicle body suspension assembly 6 in the present embodiment is mounted on the suspension mounting portion, and at this time, the suspension mounting plate 4 is provided with the suspension mounting hole 15 communicating with the suspension mounting cavity 19, the vehicle body suspension assembly 6 is mounted in the suspension mounting hole 15, and the suspension reinforcing plate 5 is also provided with the suspension mounting via hole 16 communicating with the suspension mounting cavity 19 corresponding to the suspension mounting hole 15. In particular, the suspension mounting via hole 16 is used for passing through the mounting component and the mounting tool, or for observing the mounting condition of the vehicle body suspension assembly 6, and the suspension mounting via hole 16 is provided, which can of course also facilitate the weight reduction of the suspension mounting portion.
In the present embodiment, the body suspension assembly 6 may be a suspension product that is used for connection between the frame 1 and the vehicle body 2 in a non-load-bearing vehicle body, and may be a conventional rubber suspension, for example, or may be another type of suspension structure such as a hydraulic suspension.
As an implementation form, still as shown in fig. 3, the suspension joint portion of the present embodiment includes the vehicle body floor 8, the floor reinforcing plate 10, and the floor sill beam 13, and the suspension joint chamber 20 is formed between the vehicle body floor 8, the floor reinforcing plate 10, and the floor sill beam 13. Meanwhile, as a further preferred embodiment, the suspension connection chamber 20 of the present embodiment is also divided into a plurality of suspension connection chambers which are arranged in a superimposed manner in the connection direction of the vehicle body suspension assembly 6, and thus the suspension connection section further includes the center tunnel reinforcement plate 9.
At this time, in a specific arrangement, one side of the floor reinforcement 10 near the vehicle interior is connected to the vehicle body floor 8, and the floor threshold beam 13 is connected between the other side of the floor reinforcement 10 and the vehicle body floor 8. While the center tunnel reinforcement plate 9 is connected between the vehicle body floor 8 and the floor sill beam 13 on one side and between the vehicle body floor 8 and the floor reinforcement plate 10 on the other side, and the center tunnel reinforcement plate 9 also partitions the suspension connection chamber 20 into two arranged in the connection direction of the vehicle body suspension assembly 6, that is, in the vehicle height direction.
The two suspension connection cavities 20 and the suspension mounting cavities 19 described above can be seen in fig. 6, and as can be seen from fig. 6, the two suspension connection cavities 20 and the correspondingly arranged suspension mounting cavities 19 constitute a three-cavity stacked structure arranged in the vehicle height direction. Therefore, by utilizing the three-cavity superposition structure, the structural rigidity of the suspension connection area can be better improved.
In this embodiment, correspondingly arranged suspension connection holes 17 are also provided on the floor reinforcement plate 10 and the middle channel reinforcement plate 9, and connection bushings 14 are also provided between the floor reinforcement plate 10 and the middle channel reinforcement plate 9. The suspension connection hole 17 passes through the connection sleeve 14, and in the specific implementation, with continued reference to fig. 3, the connection bolt 7 for connecting the vehicle body suspension assembly 6 passes through the suspension connection hole 17, thereby realizing connection between the suspension connection portion, i.e., the vehicle body 2 and the vehicle body suspension assembly 6. The arrangement of the connecting sleeve 14 can improve the structural strength of the connecting point of the suspension connecting part and the vehicle body suspension assembly 6 so as to ensure the connection stability between the vehicle body suspension assembly 6 and the vehicle body 2.
As shown in fig. 6, a suspension connection via 21 is also provided in the vehicle body floor 8 corresponding to the suspension connection hole 17, and the suspension connection via 21 is used for passing the connection bolt 7 and the installation tool. In order to further improve the structural strength of the connection portion at the connection position with the vehicle body suspension assembly 6, the threshold beam reinforcing plate 12 and the suspension reinforcing plate 11 are also fixedly connected to the floor reinforcing plate 10 in this embodiment. As an arrangement of the rocker reinforcement 12 and the suspension reinforcement 11, specifically, the rocker reinforcement 12 and the suspension reinforcement 11 are partially overlapped together, and both are connected to the floor rocker 13 on one side.
Wherein, one side of the threshold beam reinforcing plate 12 is specifically clamped between the floor threshold beam 13 and the floor reinforcing plate 10, and one side of the suspension reinforcing plate 11 is attached to and fixedly connected to the side wall of the floor threshold beam 13. The suspension connection hole 14 passes through the threshold beam reinforcing plate 12 and the suspension reinforcing plate 11, and one end of the connection sleeve 14 abuts against the suspension reinforcing plate 11. This results in a reinforcing of the structural strength of the vehicle body 2 at the connection point with the vehicle body suspension assembly 6.
It should be noted that, in addition to the above arrangement, the rocker reinforcement plate 12 and the suspension reinforcement plate 11 may be arranged in other ways, as long as they can also increase the structural strength of the vehicle body 2 at the connection position with the vehicle body suspension assembly 6. In addition, in addition to the above-described sill beam reinforcing plate 12 and suspension reinforcing plate 11 being provided at the same time, it is of course possible to provide only one of the sill beam reinforcing plate 12 and suspension reinforcing plate 11 in the case where the structural strength is satisfied.
As shown in fig. 4, as one of the embodiments, the frame rail 3 of the present embodiment includes a rail inner panel 301 and a rail outer panel 302 that are fastened together, and a rail reinforcing plate 303 provided in the frame rail 3. The suspension mounting portion of the present embodiment is fixedly attached to the side member outer panel 302 such that the suspension mounting portion is located specifically outside of the frame side member 3. In addition, the above-described side member reinforcing plates 303 located in the frame side member 3 are also two oppositely disposed, and the two side member reinforcing plates 303 are respectively attached to the side member inner plate 301 and the side member outer plate 302 by welding.
The two beam reinforcement plates 303 in the frame rail 3 may be of a conventional beam reinforcement plate structure, and the two beam reinforcement plates 303 may be designed approximately symmetrically along the neutral plane of the frame rail 3. However, as a preferred embodiment, in order to raise the absorption of vibration excitation by the frame rail 3, as also shown in fig. 4, the present embodiment also forms a vibration absorbing groove 304 in both rail reinforcing plates 303.
The shock absorbing grooves 304 on each side member reinforcing plate are recessed inward of the frame side member 3, and the number of the shock absorbing grooves 304 on each side member reinforcing plate 303 may be two, and the two shock absorbing grooves 304 on each side member reinforcing plate 303 are provided near both ends of the side member reinforcing plate 303, respectively. At this time, the side member reinforcement plates 303 on both sides are connected by the side member inner plate 301 and the side member outer plate 302 so that the cross section thereof may be made to assume a "dumbbell-like" structure as a whole, which can better absorb the vibration excitation transmitted from the frame rail 3.
Note that, except for making the vibration absorbing grooves 304 on each side member reinforcing plate 303 two, they are disposed near both ends of the side member reinforcing plate 303, respectively. As another embodiment, as shown in fig. 5, the shock absorbing grooves 304 on each of the side member reinforcing plates 303 may be located in the middle of the side member reinforcing plate 303. At this time, the vibration absorbing groove 304 is provided in the middle of the side member reinforcing plate 303, and can also facilitate the absorption of vibration excitation transmitted from the frame side member 3 by the integral side member reinforcing structure.
Still referring to fig. 6, a side member cavity 18 is formed in the frame side member 3 by snap-fit connection of the side member inner plate 301 and the side member outer plate 302, and due to the arrangement of the two side member reinforcing plates 303, the side member cavity 18 is also specifically divided into a side member main cavity 181 located in the middle, and shock absorbing cavities 182 provided on opposite sides of the side member main cavity 181.
In the vehicle frame and body connection structure of the present embodiment, the transmission path of external vibration excitation from various aspects of an engine, a transmission, tires, etc. during driving or idling of the whole vehicle is shown in fig. 7. Vibration excitation is transmitted to the vehicle body 2 through the frame rail 3 and the body suspension assembly 6. Inside the frame rail 3, vibration excitation can be absorbed at the frame rail 3 at first by providing the above-described rail reinforcing plate 303, in particular, the vibration absorbing grooves 304 formed on the rail reinforcing plate 303.
When the vehicle body suspension assembly 6 and the three-cavity superposition structure formed by the suspension mounting cavity 19 and the two suspension connecting cavities 20 are used, vibration excitation can be effectively absorbed by utilizing the buffering vibration isolation characteristic of a suspension product, and layer-by-layer attenuation of the vibration excitation can be realized by the three-cavity superposition structure. Therefore, the connecting structure of the embodiment can realize sufficient attenuation of vibration excitation, reduce transmission of external excitation to the inside of the cab, and improve the comfort level of driving of the vehicle.

The present embodiment relates to a vehicle employing the frame-to-body connection structure of the first embodiment, and the frame-to-body connection structure may be used for front suspension of a vehicle body as described in the first embodiment, but it may be used for rear suspension of a vehicle body as well. When the device is used for rear suspension of a vehicle body, the whole structural design is as described in the first embodiment, and each member constituting the suspension mounting portion and the suspension connecting portion is adapted or replaced based on the difference between the rear suspension position and the front suspension position of the vehicle body.
The vehicle of the embodiment can improve the rigidity of the connection area between the frame 1 and the vehicle body 3 by adopting the frame and vehicle body connection structure of the first embodiment, can reduce the transmission of external excitation to the inside of the cab, can improve the comfort level of driving the vehicle, and has good practicability.
