Description
Technical Field
[0001] This utility model belongs to the field of vehicle bottom structure, and in particular relates to a front-end module of a vehicle frame, a vehicle frame, and a vehicle. Background Technology
[0002] With the development of technology, the requirements for passenger experience are getting higher and higher, and the comfort (NVH performance) of commercial vehicles is receiving increasing attention. As the basic skeleton of the whole vehicle, the frame bears all components and transmits lateral and longitudinal loads as well as engine excitation to all parts of the vehicle body.
[0003] Vibration in the driver's area floor is a critical issue that must be addressed in high-end commercial vehicles. Conventional solutions, to ensure driver comfort, rigidly connect the driver's area floor support frame directly to the frame area above the front axle, thereby enhancing the structural strength of the driver's area and suppressing vibration transmission.
[0004] For long-distance buses, to prevent driver fatigue, it is necessary to reserve sufficient space behind the driver's area for rest. However, while the above solution can ensure driver comfort, it inevitably encroaches on the vertical space reserved for the rest area, and the overall height and width of the vehicle are limited. In other words, the existing solution cannot simultaneously meet the requirements of rest area space and driver comfort. Utility Model Content
[0005] The purpose of this invention is to provide a front-end module for a vehicle frame, thereby solving the technical problem that existing vehicle frames cannot simultaneously meet the requirements of rest area space and driver's area comfort. Another purpose of this invention is to provide a vehicle frame and vehicle to solve the same problem.
[0006] To achieve the above objectives, the technical solution for the front-end module of the vehicle frame provided by this utility model is as follows: A front-end module of a vehicle frame includes a driver's area and a rest area. The driver's area includes a front upper main longitudinal beam, a left front lower main longitudinal beam, and a right front lower main longitudinal beam. The front upper main longitudinal beam is connected to a driver's seat mounting bracket. The left front lower main longitudinal beam or the right front lower main longitudinal beam is located directly below the front upper main longitudinal beam. The rear end of the front upper main longitudinal beam is connected to a main crossbeam. The rest area includes a left rear main longitudinal beam directly opposite the left front lower main longitudinal beam and a right rear main longitudinal beam directly opposite the right front lower main longitudinal beam. The left and right rear main longitudinal beams are used to connect to the front axle module of the frame. The main crossbeam is connected to a middle crossbeam through a left upper vertical beam and a right upper vertical beam. The left and right upper vertical beams are located in front of the left rear main longitudinal beam and the right rear main longitudinal beam, respectively. The left front lower main longitudinal beam, the right front lower main longitudinal beam, the left rear main longitudinal beam, and the right rear main longitudinal beam are all connected to the middle crossbeam.
[0007] As a further improvement, a lower crossbeam is connected below the middle crossbeam via a lower left vertical beam and a lower right vertical beam. The lower left vertical beam and the lower right vertical beam are located directly below the upper left vertical beam and the upper right vertical beam, respectively. The lower crossbeam is connected to a lower left secondary longitudinal beam and a lower right secondary longitudinal beam, which are located directly below the left rear main longitudinal beam and the right rear main longitudinal beam, respectively. Rear diagonal braces are connected between the left rear main longitudinal beam and the left rear secondary longitudinal beam, and between the right rear main longitudinal beam and the right rear secondary longitudinal beam.
[0008] As a further improvement, the angle between the rear diagonal brace and the horizontal plane is 30°~60°.
[0009] As a further improvement, for the case where the left front lower main longitudinal beam is located directly below the front upper main longitudinal beam, the main crossbeam is connected to the front upper secondary longitudinal beam located to the right of the front upper main longitudinal beam. The front upper secondary longitudinal beam is located directly above the right front lower main longitudinal beam.

The front upper secondary longitudinal beam is located directly above the left front lower main longitudinal beam.

[0014] This invention is a pioneering creation with the following beneficial effects: The front axle module of this invention is equipped with main longitudinal beams and main cross beams as the main load-bearing components. The relevant components of the driver's area and rest area are connected by the main longitudinal beams and main cross beams to form a strong frame structure, improving the stiffness and modal frequency of the front-end module. Furthermore, this frame structure serves as a major control node on the vibration energy transmission path.

The rear main longitudinal beam can be connected to the front axle module of the chassis. Vibration excitation from the front axle can be repeatedly transmitted, reflected, and dissipated within the high-rigidity frame structure before reaching the driver's area, dispersing energy and ensuring the NVH performance of the driver's area. In addition, the front axle module still provides a rest area vertically, facilitating driver rest and thus meeting the vehicle's requirements for rest area space and driver's area NVH performance.

[0035] To provide a vehicle that offers both superior NVH performance and a rest area, the basic technical concept of this invention is a completely redesigned front-end frame module. The front-end frame module can be divided into a driver's area and a rest area, with the rest area positioned lower than the driver's area. Both the driver's area and the rest area include longitudinal beams with large cross-sections and high rigidity, and a crossbeam with a large cross-section and high rigidity connects the driver's area and the rest area. The longitudinal beams and crossbeams are emphasized here as the main load-bearing framework of the front-end frame module, enabling the front-end module to have high rigidity and high modal frequency, thus meeting the vehicle's NVH requirements while retaining the driver's area.
[0036] Based on the above concept, the present invention will be further described in detail below with reference to the embodiments.
[0037] Specific implementation of the front-end module of the vehicle frame provided by this utility model: The front-end module of the chassis provided in this embodiment serves as the foremost part of the chassis, such as... Figure 1 and Figure 2 As shown, it can be connected to the front of the front axle module C of the frame. The front module as a whole includes a driver's area A and a rest area B. The driver's area A is located in front of the rest area B. Both the driver's area A and the rest area B are frame structures formed by connecting crossbeams, longitudinal beams, vertical beams, diagonal braces, etc. Specifically, the longitudinal beams include main longitudinal beams with large cross sections as the main load-bearing components, and the crossbeams also include main crossbeams 201 with large cross sections as the main load-bearing components.
[0038] More specifically, such as Figures 3-5As shown, the driver's area includes a front upper main longitudinal beam 101, which is located at the front and uppermost level. The front upper main longitudinal beam 101 is connected to a driver's seat mounting bracket 600, on which the driver's seat can be mounted. The driver's area also includes a left front lower main longitudinal beam 102 and a right front lower main longitudinal beam 103, located at the lower left and lower right sides, respectively. One of the left front lower main longitudinal beam 102 and the right front lower main longitudinal beam 103 is located directly below the front upper main longitudinal beam 101. For left-hand drive models, the driver's seat is located on the left side of the frame; correspondingly, the front upper main longitudinal beam 101 is located on the left side of the frame, and the left front lower main longitudinal beam 102 is located directly below the front upper main longitudinal beam 101. For right-hand drive models, the driver's seat is located on the right side of the frame, and correspondingly, the upper front main longitudinal beam 101 is located on the right side of the frame, and the lower right front main longitudinal beam 103 is located directly below the upper front main longitudinal beam 101.
[0039] The front upper main longitudinal beam 101 is connected to the rear of the main cross beam 201, which serves as a partition structure between the driver's area and the rest area.
[0040] The rest area includes a left rear main longitudinal beam 105 and a right rear main longitudinal beam 104. The left rear main longitudinal beam 105 is located directly behind the left front lower main longitudinal beam 102, and the right rear main longitudinal beam 104 is located directly behind the right front lower main longitudinal beam 103. The left rear main longitudinal beam 105 and the right rear main longitudinal beam 104 can connect to the front axle module of the frame.
[0041] For the front-end module of the frame, there are not only the main crossbeam 201 and the main longitudinal beams mentioned above, but also other crossbeams and longitudinal beams. The main crossbeam 201 and the main longitudinal beams refer to crossbeams and longitudinal beams with larger cross sections and stronger rigidity than other crossbeams and longitudinal beams.
[0042] A middle crossbeam 202 is connected below the main crossbeam 201. The main crossbeam 201 is connected to the middle crossbeam 202 via the upper left vertical beam 301 and the upper right vertical beam 302. The upper left vertical beam 301 and the upper right vertical beam 302 are located in front of the left rear main longitudinal beam 105 and the right rear main longitudinal beam 104, respectively, specifically directly in front. The lower left front main longitudinal beam 102, the lower right front main longitudinal beam 103, the left rear main longitudinal beam 105, and the right rear main longitudinal beam 104 are all connected to the middle crossbeam 202.
[0043] As described above, in this embodiment, the front upper main longitudinal beam 101, left front lower main longitudinal beam 102, right front lower main longitudinal beam 103, main crossbeam 201, left rear main longitudinal beam 105, and right rear main longitudinal beam 104 can be connected by the middle crossbeam 202, left upper vertical beam 301, and right upper vertical beam 302 to form an integral frame structure with high strength and stiffness. This frame structure can serve as the main control node on the vibration energy transmission path, improving the stiffness and modal frequency of the front-end module. Vibration excitation (engine excitation and road excitation) transmitted forward from the front axle module can be repeatedly transmitted, reflected, and consumed in the frame structure before reaching the driver's area. Moreover, the frame structure itself is a multi-level hierarchical control structure, and by the time it reaches the driver's seat, it has been largely consumed. At the same time, the main crossbeam 201 is located at the junction of the driver's area and the rest area, serving as a key barrier for the transmission of vibration from the driver's area to the rest compartment and for the upward transmission of vibration from the frame.
[0044] Based on the above analysis, it can be seen that the driver's seat mounting bracket in the driver's area of this embodiment is not directly connected to the front axle module through the longitudinal beam. Instead, it is set with an upper and lower layered structure and connected to the front axle module through the main longitudinal beam of the rest area. While meeting NVH performance requirements, it retains the rest area to meet the driver's rest needs.
[0045] As a preferred implementation method, such as Figures 3-5 As shown, a left rear secondary longitudinal beam 502 and a right rear secondary longitudinal beam 501 are respectively provided below the left rear main longitudinal beam 105 and the right rear main longitudinal beam 104. Diagonal braces are also connected between the left rear main longitudinal beam 105 and the left rear secondary longitudinal beam 502, and between the right rear main longitudinal beam 104 and the right rear secondary longitudinal beam 501. Correspondingly, these diagonal braces can be defined as rear diagonal braces 401. This forms a reinforced triangular structure, improving the rigidity of the rest area and further dispersing the energy transmitted from vibration excitation, guiding the vibration excitation to the lower layer of the rest area, minimizing the vibration transmitted to the driver's area, and also improving the overall rigidity of the frame. Specifically, a lower crossbeam 203 is connected below the middle crossbeam 202. Most fundamentally, the middle crossbeam 202 and the lower crossbeam 203 can be connected via a left lower vertical beam 303 and a right lower vertical beam 304, where the left lower vertical beam 303 and the right lower vertical beam 304 are located directly below the left upper vertical beam 301 and the right upper vertical beam 302, respectively. Of course, depending on actual needs and for ease of vehicle body installation, other auxiliary vertical beams can be connected between the middle crossbeam 202 and the lower crossbeam 203. The rear end of the lower crossbeam 203 is connected to the left rear secondary longitudinal beam 502 and the right rear secondary longitudinal beam 501. The rear diagonal brace 401 is a diagonal brace that is inclined vertically, connecting between the left rear main longitudinal beam 105 and the left rear secondary longitudinal beam 502, and between the right rear main longitudinal beam 104 and the right rear secondary longitudinal beam 501, respectively.
[0046] Preferably, the angle between the rear diagonal brace 401 and the horizontal plane is 30° to 60°, for example, it can be 30°, 40°, 45°, 50°, 60°, or other values within this range. Through repeated calculations, within this range, the stiffness and modal separation effect of the front-end module can be maximized.
[0047] Furthermore, to further enhance the rigidity and energy dissipation effect of the rest area, such as... Figures 3-5 As shown, diagonal braces are connected between the lower crossbeam 203 and the left rear secondary longitudinal beam 502, and between the lower crossbeam 203 and the right rear secondary longitudinal beam 501. These diagonal braces can be defined as horizontal diagonal braces 403.
[0048] In addition, an auxiliary diagonal brace 404 is connected at the rear end of the central crossbeam 202 between the left rear main longitudinal beam 105 and the right rear main longitudinal beam 104 to further enhance the rigidity and energy dissipation effect of the rest area.
[0049] To facilitate vehicle body installation, an auxiliary longitudinal beam 106 is connected to the rear end of the central crossbeam 202. Specifically, the number of auxiliary longitudinal beams 106 can be four as shown in the figure.
[0050] In addition to providing a diagonal brace (rear diagonal brace 401) in the rest area, preferably, a diagonal brace (front diagonal brace 402) can also be provided in the driver's area. Specifically, for Figures 3-5 For the front-end module shown for a left-hand drive vehicle, a front diagonal brace 402 connects the upper front main longitudinal beam 101 and the lower left front main longitudinal beam 102. Correspondingly, on the right side of the upper front main longitudinal beam 101, a lower front secondary longitudinal beam 503 connected to the main crossbeam 201 is provided. The upper front secondary longitudinal beam 503 is located directly above the lower right front main longitudinal beam 103, and a front diagonal brace 402 also connects the upper front secondary longitudinal beam 503 and the lower right front main longitudinal beam 103.
[0051] After the vibration excitation is transmitted to the driver's area, the frame of the driver's area acts as a whole under the action of the front diagonal brace 402, which can disperse the energy to minimize the energy transmission to the driver's seat position and improve driving comfort.
[0052] Preferably, the angle between the front diagonal brace 402 and the horizontal plane can be the same as the angle between the rear diagonal brace 401 and the horizontal plane, that is, the front diagonal brace 402 and the rear diagonal brace 401 are parallel. This makes it easier to form force flow guidance and reduce the vibration response in the driver's area.
[0053] Understandably, for a front-end module suitable for right-hand drive vehicles, the driver's seat mounting bracket is located on the right side of the front-end module. Correspondingly, the right front lower main longitudinal beam is located below the front upper main longitudinal beam, and a front diagonal brace connects the right front lower main longitudinal beam and the front upper main longitudinal beam. The front end of the main crossbeam is connected to a front upper secondary longitudinal beam located to the left of the front upper main longitudinal beam. This front upper secondary longitudinal beam is located above the left front lower main longitudinal beam, and a front diagonal brace connects the front upper secondary longitudinal beam and the left front lower main longitudinal beam. Similarly, the angle between the front diagonal brace and the horizontal plane can be the same as the angle between the rear diagonal brace and the horizontal plane.
[0054] It should be noted that, considering the need for lightweighting, apart from the main crossbeam 201 and each main longitudinal beam mentioned above, other structural beams can use profiles with smaller cross sections. However, it is not excluded that in some alternative implementations, other structural beams may be replaced with profiles with larger cross sections.
[0055] Furthermore, welding can be used to connect the aforementioned structural beams.
[0056] Specific embodiments of the vehicle frame provided by this utility model: Depending on the position of the frame and the different components it supports, the frame can be divided into front-end module, front axle module, mid-section module, drive axle module, etc. The front-end module is connected to both ends of the front axle module. The specific structure of the front section module is the same as the implementation method of the frame front axle module mentioned above, and will not be described in detail here.
[0057] Specific embodiments of the vehicle provided by this utility model: The vehicle includes the frame described in the above-described frame implementation, which will not be further described here.
[0058] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model.
