In addition, the frame is also provided with a front suspension structure and a rear suspension structure so as to facilitate the installation of the shell of the passenger car.
The two long stringers of the frame extend from the head to the tail, if the position of the driving area of the passenger car is to be structurally changed, the arrangement form of the front suspension and the rear suspension of the whole passenger car needs to be redesigned, and the redesign also means that performance evaluation needs to be carried out again, for example, the fatigue durability of the rear suspension section of the frame needs to be further evaluated, and the workload is huge.
Therefore, the height of the driving area of the existing passenger car is difficult to adjust, the flexibility of the driving area structure is very limited, and different requirements of users on the driving area are difficult to meet.
In view of the above, an embodiment of the present application provides a vehicle frame and a passenger car, wherein the vehicle frame includes a driving section and a front suspension section, the driving section is connected to a side of the front suspension section facing a front end of the passenger car, and one of an end of the driving section facing the front suspension section and an end of the front suspension section facing the driving section is provided with a plurality of mounting positions, so that the other one is connected to any one of the plurality of mounting positions; and particularly, the plurality of mounting positions are arranged at intervals along the height direction of the passenger car, so that the driving section can be mounted at positions with different heights relative to the front suspension section, and different requirements of users on the driving area of the passenger car are met.
The following describes the frame and the passenger car provided by the embodiment of the application in detail with reference to the accompanying drawings.
Example 1
Fig. 1 is a schematic view of a vehicle frame according to an embodiment of the present application. As shown in fig. 1, the vehicle frame provided in the embodiment of the present application includes a front suspension section 100 and a driver section 200, and the driver section 200 is connected to one end of the front suspension section 100 facing the front end of the passenger car. By sectionally arranging the driving section 200 and the front suspension section 100, the driving section 200 can be independently adjusted under the condition that the structures of other parts such as the front suspension section 100 are kept unchanged, other parts of the passenger car do not need to be correspondingly adjusted while the driving section 200 is adjusted, and the adjustment and the arrangement of the driving section 200 are convenient and simple.
Specifically, one of an end of the driving section 200 facing the front suspension section 100 and an end of the front suspension section 100 facing the driving section 200 has a plurality of mounting positions 300, and the other is connected to any one mounting position 300 of the plurality of mounting positions 300; wherein, a plurality of installation sites 300 are arranged at intervals along the height direction of the passenger car. In this way, the driving section 200 can be installed at different heights relative to the front suspension section 100, so that the flexibility of the driving section 200 is improved, the height of the driving section 200 can be changed, the bottom surface height and the space size of the driving area of the corresponding passenger car can be changed, and the frame can be suitable for passenger cars with driving areas in different arrangement forms so as to meet different requirements of users on the driving areas of the passenger cars.
For example, the plurality of mounting locations 300 may be uniformly spaced apart and spaced apart at appropriate intervals to facilitate adjustment of the driver's section 200 such that the driver's section 200 may be positioned at an appropriate height relative to the front suspension section 100.
It should be noted that the frame shown in fig. 1 is not a complete frame, and the frame further includes a rear suspension section located at the rear of the passenger car in addition to the driver section 200 and the front suspension section 100 located at the front of the passenger car, where the junction of the front suspension section 100 and the rear suspension section is an integral structure, and the two sections are located at the same height, and the relative height between the two sections is not adjustable.
Fig. 2 is a schematic view of the front suspension section of fig. 1. As shown in fig. 2, the front suspension section 100 may include two first stringers 110, each of the two first stringers 110 extending along a length direction of the passenger car, and the two first stringers 110 being disposed at intervals along a width direction of the passenger car.

In the present embodiment, an end of the first longitudinal beam 110 facing the front end of the passenger car is defined as a front end of the first longitudinal beam 110, and an end of the first longitudinal beam 110 facing the rear end of the passenger car is defined as a rear end of the first longitudinal beam 110; similarly, an end of the second side member 210 toward the front end of the passenger car is defined as the front end of the second side member 210, and an end of the second side member 210 toward the rear end of the passenger car is defined as the rear end of the second side member 210. The rear end of the second side member 210 is connected to the front end of the first side member 110, which means that the front end of the first side member 110 faces the rear end of the second side member 210, and the rear end of the second side member 210 faces the front end of the first side member 110.
Wherein, the mounting position 300 may be disposed at an end of the first longitudinal beam 110 facing the second longitudinal beam, i.e., the mounting position 300 may be disposed at a front end of the first longitudinal beam 110; alternatively, the mounting location 300 may be provided at an end of the second longitudinal beam 210 facing the first longitudinal beam 110, i.e. the mounting location 300 may be provided at a rear end of the second longitudinal beam 210. The second longitudinal beam 210 is movable relative to the first longitudinal beam 110 no matter where the mounting location 300 is located, and thus the driver's leg 200 may be moved relative to the front suspension section 100.
In addition, since the second longitudinal beam 210 plays a main bearing role in the driving area of the passenger car, the load is larger, and the outer wall surface of the second longitudinal beam 210 may be covered with a reinforcing plate (not shown in the figure) to improve the overall rigidity of the second longitudinal beam 210 and improve the load capacity of the second longitudinal beam 210. In practice, the second stringers 210 and the reinforcement plate may be bolted together to ensure the reliability of the connection.
One of an end of the first side member 110 facing the second side member 210 and an end of the second side member 210 facing the first side member 110 may be connected with the first connector 400, i.e., one of a front end of the first side member 110 and a rear end of the second side member 210 may be connected with the first connector 400, and the other may be connected with the first connector 400.
The first connecting piece 400 is extended along the height direction of the passenger car, the plurality of mounting positions 300 may be a plurality of first mounting holes 411 disposed at intervals along the height direction of the first connecting piece 400, and the second longitudinal beam 210 may move along the height direction of the passenger car relative to the first longitudinal beam 110, so that the driving section 200 may move along the height direction of the passenger car relative to the front suspension section 100, so as to improve the flexibility of the driving area structure of the passenger car.
Fig. 4 is a partial enlarged view of a portion a in fig. 2. As shown in fig. 4, in one possible example, the first connector 400 may be connected to an end of the first side member 110 facing the second side member 210, i.e., the first connector 400 may be connected to a front end of the first side member 110.
Specifically, an upper section of the first connector 400 near the top of the passenger car may be connected to an end surface of the first longitudinal beam 110, and a lower section of the first connector 400 extends out of the first longitudinal beam 110, and the height of the driving section 200 may be adjusted downward, so as to reduce the bottom surface height of the driving area of the passenger car and increase the space size of the driving area. Alternatively, a lower section of the first connecting member 400 near the bottom of the passenger car may be connected to an end surface of the first longitudinal beam 110, and an upper section of the first connecting member 400 protrudes beyond the first longitudinal beam 110.
For example, the first connector 400 may include a first front plate 410 and two first side plates 420, the first front plate 410 corresponding to an end surface of the first side member 110, and the first mounting hole 411 provided on the first front plate 410; the two first side plates 420 are respectively connected to opposite sides of the first front plate 410, and the two first side plates 420 are respectively connected to outer side walls of two sides of the first longitudinal beam 110, so as to realize connection between the first connecting piece 400 and the first longitudinal beam 110.
In actual manufacturing, the first front plate 410 and the two first side plates 420 may be integrally formed, or the first front plate 410 and the first side plates 420 may be spliced. As shown in fig. 4, the first connector 400 may include two first folded plates, the first folded plates include a first front plate 410 and a first side plate 420, the first side plate 420 is connected to a side edge of the first front plate 410, the first front plates 410 of the two first folded plates are overlapped and disposed on an end surface of the first longitudinal beam 110, and the two first side plates 420 are respectively located at opposite sides of the first longitudinal beam 110.
To improve the reliability of the connection of the first connecting member 400 to the first side member 110, the first side plate 420 may be partially widened, i.e., the first side plate 420 may have a widened portion 421, and the widened portion 421 is connected to the outer sidewall of the first side member 110. In this way, on the basis of ensuring that the overall size of the first connecting piece 400 is smaller and the weight is lighter, the connecting area of the connecting part of the first connecting piece 400 and the first longitudinal beam 110 is increased, so that the first connecting piece 400 and the first longitudinal beam 110 are connected more firmly.
Specifically, the widened portion 421 may be provided with a first plug welding hole 422, and the first connector 400 and the first longitudinal beam 110 may be welded together to enhance the connection strength therebetween.
In addition, the first connector 400 may further include a first auxiliary mounting plate 430 to facilitate positioning and mounting. As shown in fig. 4, the first auxiliary mounting plate 430 includes a cross plate 431 and a vertical plate 432, the vertical plate 432 is mounted at one side of the cross plate 431 and extends toward the bottom of the passenger car, the cross plate 431 is located at the top end of the first front plate 410 and the two first side plates 420 facing the top of the passenger car, and the vertical plate 432 is connected to the first side plates 420. When the transverse plate 431 is installed, the transverse plate 431 can be abutted against the top surface of the first cross beam 120 facing the top of the passenger car, so that the positioning of the first connecting piece 400 can be realized quickly, the connection strength of the connecting part of the first connecting piece 400 and the first longitudinal beam 110 can be improved, and the connection reliability of the first connecting piece 400 and the first longitudinal beam 110 is improved.
As shown in fig. 2 and 4, the vehicle frame provided by the embodiment of the application may further include a first cross member 120, where the first cross member 120 is suspended at an end of the first longitudinal member 110 near the second longitudinal member 210, and the first cross member 120 is located at a side of the first longitudinal member 110 facing the bottom of the passenger car, and a reinforcement member 600 is connected between the first connector 400 and the first cross member 120. The reinforcement member 600 may provide a supporting force to the first connector 400, and increase the local rigidity of the first connector 400 to prevent the first connector 400 from being deformed due to long-term stress.
Specifically, both sides of the reinforcement member 600 may be connected to the first connection member 400 through the first connection plate 700, one end of the first connection plate 700 is fixed to the first side plate 420 of the first connection member 400, and the other end of the first connection plate 700 is fixed to the outer wall surface of the reinforcement member 600 to enhance the connection strength between the reinforcement member 600 and the first connection member 400.
Referring again to fig. 2, a third cross member 130 may be further connected between the two first connecting members 400 to enhance the structural strength of the front suspension section 100, and in addition, a plurality of cross members may be further connected between the two first longitudinal members 110, and the third cross member 130 and the plurality of cross members may jointly ensure the torsional rigidity and the bending strength of the front suspension section 100.
As shown in fig. 1, in practical application, the cross-sectional dimension of the second longitudinal beam 210 is generally smaller, so that it is inconvenient to connect with the first connecting member 400, and therefore, in this embodiment, the end of the second longitudinal beam 210 facing the first longitudinal beam 110 may be connected with the second connecting member 500, and the second connecting member 500 is connected with the first connecting member 400 at a position corresponding to the first mounting hole 411, so as to connect the first longitudinal beam 110 with the first connecting member 400.
Fig. 5 is a schematic diagram of the second connector 500 in fig. 3. As shown in fig. 3 and 5, at least one second mounting hole 511 may be formed in the second connector 500, and the second mounting hole 511 is disposed corresponding to the first mounting hole 411, so that the reliability of the connection between the first connector 400 and the second connector 500 is ensured by inserting a locking member (not shown) into the corresponding second mounting hole 511 and first mounting hole 411.
In addition, the apertures of the first mounting holes 411 and the second mounting holes 511 may be set to the same size, for example, the apertures of the first mounting holes 411 and the second mounting holes 511 may be 15mm, 20mm, 28mm, or the like; and, the locking member can be tightly inserted into the first mounting hole 411 and the second mounting hole 511 to avoid the second mounting member from being displaced relative to the first mounting member after being stressed.
In this example, two second mounting holes 511 may be disposed on the second connecting member 500 along the height direction of the passenger car, and the interval between the two second mounting holes 511 may be the same as the interval between the two adjacent first mounting holes 411, so as to ensure that each of the two second mounting holes 511 may have a corresponding first mounting hole 411, so as to improve the connection strength between the first connecting member 400 and the second connecting member 500; or the interval between the two second mounting holes 511 may be the same as the distance between the three or more first mounting holes 411 to improve the accuracy of the height adjustment of the driver's leg 200.
