Referring below Figures 1 - 3 to describe the vehicle frame 100 according to an embodiment of the present utility model, including: a vehicle frame body 10, a first suspension assembly 20, and a second suspension assembly 30.
[0030] Specifically, as Figure 1 and Figure 2As shown, the vehicle frame body 10 includes a first vehicle frame 11 and a second vehicle frame 12. One end of the first vehicle frame 11 and the second vehicle frame 12 is connected, and the other ends of the first vehicle frame 11 and the second vehicle frame 12 are spaced apart from each other. The first suspension assembly 20 is connected to the second vehicle frame 12, and the first suspension assembly 20 is disposed between the first vehicle frame 11 and the second vehicle frame 12. The second suspension assembly 30 is disposed at the other ends of the first vehicle frame 11 and the second vehicle frame 12, and the second suspension assembly 30 is respectively connected to the first vehicle frame 11 and the second vehicle frame 12.
[0031] The first vehicle frame 11 includes two first sub-vehicle frames 111 and a second sub-vehicle frame 112. The two first sub-vehicle frames 111 are arranged in parallel. The second sub-vehicle frame 112 is disposed between the two first sub-vehicle frames 111. One ends of the two first sub-vehicle frames 111 are respectively away from the second sub-vehicle frame 112, and the other ends of the two first sub-vehicle frames 111 extend in the direction of the second sub-vehicle frame 112 along the length direction A of the vehicle frame body 10 and are perpendicularly connected to both ends of the second sub-vehicle frame 112. The second vehicle frame 12 includes two third sub-vehicle frames 121. The two third sub-vehicle frames 121 are arranged along the length direction A of the vehicle frame body 10. One ends of the two third sub-vehicle frames 121 are away from the second sub-vehicle frame 112, and the other ends are adjacent to the second sub-vehicle frame 112. One ends of the two third sub-vehicle frames 121 away from the second sub-vehicle frame 112 are respectively connected to the two first sub-vehicle frames 111, and the other ends of the two first sub-vehicle frames 111 adjacent to the second sub-vehicle frame 112 and the other ends of the two third sub-vehicle frames 121 adjacent to the second sub-vehicle frame 112 are spaced apart along the height direction C of the vehicle frame body 10.
[0032] In this embodiment, one end of each of the two first subframes 111 away from the second subframe 112 is respectively connected to one end of each of the two third subframes 121 away from the second subframe 112. The other ends of the two first subframes 111 adjacent to the second subframe 112 are spaced apart from each other along the height direction C of the second subframe 112. Among them, the other end of the first subframe 111 adjacent to the second subframe 112 gradually inclines and extends towards the third subframe 121 in the direction away from the second subframe 112, and is respectively connected to the third subframe 121. In addition, the two ends of the two third subframes 121 approach each other in the direction of being adjacent to each other. That is, the two ends of the third subframe 121 respectively incline and extend towards each other. The second suspension assembly 30 is arranged along the height direction C of the vehicle frame body 10. The second suspension assembly 30 is arranged between the third subframe 121 and the second subframe 112 at the other end of the third subframe 121 adjacent to the second subframe 112, and the second suspension assembly 30 is respectively connected to the second subframe 112 and the two third subframes 121. In this embodiment, the vehicle frame 100 is used to mount the power assembly 200, reduce the influence of the vibration transmitted on the power assembly 200 on the vehicle frame 100, so that the influence of the vibration transmitted by the power assembly 200 on the vehicle frame 100 can be mitigated and filtered through the arrangement of the first suspension assembly 20 and the second suspension assembly 30.
[0033] For the vehicle frame 100 according to the embodiment of the present invention, by arranging the first suspension assembly 20 to be connected to the second vehicle frame 12, the vibration transmission between the power assembly 200 and the vehicle frame body 10 can be reduced, and at the same time, the structural strength of the second vehicle frame 12 can be improved; by arranging the second suspension assembly 30 to be respectively connected to the first vehicle frame 11 and the second vehicle frame 12, the vibration transmission along the height direction C of the vehicle frame body 10 on the first vehicle frame 11 and the second vehicle frame 12 can be reduced, the energy of the vibration of the power assembly 200 and the road surface excitation force transmitted to the vehicle frame 100 can be attenuated, the vibration isolation performance of the vehicle frame 100 and the NVH performance of the vehicle can be improved, and the structural strength of the vehicle frame body 10 can be improved.
[0034] In this embodiment, the vehicle frame body 10 further includes a reinforcing member 13. The reinforcing member 13 is respectively connected to one end of each of the two third subframes 121 away from the second subframe 112, which can improve the structural strength of the vehicle frame body 10. Optionally, there are multiple reinforcing members 13. The multiple reinforcing members 13 include a first reinforcing member and a second reinforcing member. The first reinforcing member is connected to one end of each of the two third subframes 121 away from the second subframe 112, and the second reinforcing member is connected to one end of each of the two first subframes 111 away from the second subframe 112, and the first reinforcing member and the second reinforcing member are spaced apart.
[0035] According to some embodiments of the present invention, such as Figure 2 and Figure 3As shown in the figure, the second suspension assembly 30 includes a first suspension member 31 and a second suspension member 32. One end of the first suspension member 31 is connected to the first vehicle frame 11; one end of the second suspension member 32 is connected to the second vehicle frame 12, and the other ends of the first suspension member 31 and the second suspension member 32 are arranged at intervals.
[0036] The first suspension member 31 and the second suspension member 32 are arranged at intervals along the height direction C of the vehicle frame body 10, and the ends of the first suspension member 31 and the second suspension member 32 that are far away from each other are respectively connected to the corresponding first vehicle frame 11 and second vehicle frame 12.
[0037] Thus, by connecting the ends of the first suspension member 31 and the second suspension member 32 that are far away from each other to the first vehicle frame 11 and the second vehicle frame 12 respectively, and arranging and aligning the other ends of the first suspension member 31 and the second suspension member 32 at intervals along the height direction C of the vehicle frame body 10, the other ends of the first vehicle frame 11 and the second vehicle frame 12 that are adjacent to each other can be arranged relatively and at intervals along the height direction C of the vehicle frame body 10, which can reduce the transmission of vibration between the first suspension member 31 and the second suspension member 32, that is, reduce the vibration transmission from the powertrain 200 to the vehicle frame 100, and improve the sound insulation effect of the vehicle.
[0038] According to some embodiments of the present invention, as Figure 2 and Figure 3 shown in the figure, both the first suspension member 31 and the second suspension member 32 include a first suspension part 33 and a second suspension part 34. One end of the first suspension part 33 of the first suspension member 31 is connected to the first vehicle frame 11, and one end of the first suspension part 33 of the second suspension member 32 is connected to the second vehicle frame 12; one end of the second suspension part 34 of the first suspension member 31 is connected to the other end of the first suspension part 33 of the first suspension member 31, and one end of the second suspension part 34 of the second suspension member 32 is connected to the other end of the first suspension part 33 of the second suspension member 32, and the other ends of the second suspension part 34 of the first suspension member 31 and the second suspension part 34 of the second suspension member 32 are arranged at intervals.
[0039] That is, the first suspension member 31 is connected to the first vehicle frame 11 through the first suspension part 33, the end of the first suspension part 33 far away from the first vehicle frame 11 is connected to the second suspension part 34, the second suspension member 32 is connected to the second vehicle frame 12 through the first suspension part 33, the end of the first suspension part 33 of the second suspension member 32 far away from the second vehicle frame 12 is connected to the second suspension part 34 of the second suspension member 32, and the second suspension part 34 of the first suspension member 31 and the second suspension part 34 of the second suspension member 32 are arranged at intervals. And the first suspension part 33 and the second suspension part 34 of the first suspension member 31 and the second suspension member 32 are aligned along the height direction C of the vehicle frame body 10.
[0040] Therefore, a first suspension part 33 and a second suspension part 34 are provided on both the first suspension member 31 and the second suspension member 32, and the first suspension part 33 and the second suspension part 34 on the first suspension member 31 and the second suspension member 32 are aligned along the height direction C of the vehicle frame body 10, so that the other ends of the second sub-frame 112 and the two third sub-frames 121 away from each other's connection are uniformly stressed along the height direction C of the vehicle frame body 10, and the vibration transmission effect between the second suspension assemblies 30 is attenuated.
[0041] Further, as Figure 2 and Figure 3 shown, the first suspension part 33 is a rubber part, and the second suspension part 34 is a magnetic part; the magnetic properties of the second suspension part 34 of the first suspension member 31 and the second suspension part 34 of the second suspension member 32 are the same.
[0042] The first suspension part 33 of the second suspension assembly 30 is a rubber part and is made of rubber material. Rubber is a highly elastic polymer material with reversible deformation. It has strong elasticity at room temperature, can produce large deformation under very small external force, and can return to its original state after the external force is removed. The second suspension part 34 of the second suspension assembly 30 is a magnetic part. The magnetic properties of the second suspension part 34 of the first suspension member 31 and the second suspension part 34 of the second suspension member 32 are the same, so that the second suspension parts 34 adjacent to each other between the first suspension member 31 and the second suspension member 32 repel each other. When the vibrating part of the power assembly 200 is transmitted to the second vehicle frame 12 through the first suspension assembly 20, part of the vibration is transmitted to the first vehicle frame 11 through the connection with the first vehicle frame 11. However, since the ends of the first vehicle frame 11 and the second vehicle frame 12 where the second suspension assembly 30 is provided are spaced apart from each other, and since the two adjacent second suspension parts 34 repel each other, the two second suspension parts 34 included in the same second suspension assembly 30 interact with each other, which is opposite to the vibration transmission path between the first vehicle frame 11 and the second vehicle frame 12, so that the vibration transmission between the first vehicle frame 11 and the second vehicle frame 12 can be effectively reduced. In this embodiment, the magnetic part is a neodymium magnet structural part. Neodymium magnet is one of the strongest permanent magnet materials at present. Its magnetic force can reach several times that of other permanent magnet materials, its structural strength is relatively high, it is not easy to fall off and oxidize, and it can maintain magnetism for a long time and has a long service life.
[0043] Accordingly, the first suspension part 33 is a rubber part, and the second suspension part 34 is a magnetic part. When vibration is transmitted to the second suspension assembly 30, the first suspension part 33 can block the contact between the second suspension part 34 and the corresponding vehicle frame 100, improving the vibration damping effect. At the same time, the magnetic properties of the second suspension part 34 of the first suspension member 31 and the second suspension part 34 of the second suspension member 32 are the same. According to the principle of like poles repelling each other, a repulsive force is generated between the second suspension part 34 of the first suspension member 31 and the second suspension part 34 of the second suspension member 32. Part of the repulsive force in the second suspension assembly 30 can offset part of the vibration, further reducing vibration transmission, attenuating vibration energy, and enhancing the stability of the vehicle frame body 10.
[0044] According to some embodiments of the present invention, as Figure 1 and Figure 2 shown, the vehicle frame 100 further includes: a first connecting plate 40. The first connecting plate 40 is connected to the first vehicle frame 11 at the other end of the vehicle frame body 10, that is, at the other end where the first vehicle frame 11 and the second vehicle frame 12 are spaced apart along the height direction C of the vehicle frame body 10. At least one first suspension member 31 is connected to the first connecting plate 40.
[0045] The first connecting plate 40 is adapted to be connected to the first suspension assembly 20. One end of the first connecting plate 40 is connected to the side of the second sub-vehicle frame 112 of the first vehicle frame 11 away from the reinforcing member 13. The other end of the first connecting plate 40 extends in the length direction A of the vehicle frame body 10 away from the second sub-vehicle frame 112, and one end of at least one first suspension member 31 is connected to the end of the first connecting plate 40 adjacent to the two third sub-vehicle frames 121 and adjacent to the second sub-vehicle frame 112. In this embodiment, the vehicle frame 100 includes two identical first connecting plates 40. One ends of the two first connecting plates 40 are both connected to the second sub-vehicle frame 112 and are spaced apart along the width direction B of the vehicle frame body 10. The two first connecting plates 40 correspond to two second suspension assemblies 30, and one first suspension member 31 is provided on each first connecting plate 40. The first suspension member 31 and the first connecting plate 40 are fixedly connected by fasteners. For example, the first connecting plate 40 and the first suspension member 31 can be connected by bolts.
[0046] Accordingly, by providing the first connecting plate 40, it is convenient for the first suspension member 31 to be connected to the first vehicle frame 11 through the first connecting plate 40, effectively attenuating the vibration transmitted to the first vehicle frame 11. At the same time, the connection strength and stability between the first suspension member 31 and the first vehicle frame 11 are improved, facilitating the installation of the first suspension member 31.
[0047] In this embodiment, the vehicle frame 100 further includes a support plate 15. The support plate 15 is connected to the third sub-frame 121 and is located at one end of the third sub-frame 121 adjacent to the second sub-frame 112. The support plate 15 is horizontally arranged on the third sub-frame 121. The second suspension assembly 30 is adapted to be installed on the support plate 15. Specifically, the second suspension member 32 of the second suspension assembly 30 is fixedly connected to the support plate 15. Wherein, the support plate 15 includes a first support plate 15 and a second support plate 15. The first support plate 15 and the second support plate 15 are respectively arranged at both ends of the other ends of the two third sub-frames 121 along the height direction C of the vehicle frame body 10. The first support plate 15 and the second support plate 15 face each other along the height direction C of the vehicle frame body 10, facilitating the fastener to pass through the first support plate 15 and the second support plate 15 to connect the second suspension member 32. Thus, by providing the support plate 15 on the third sub-frame 121 and connecting the support plate 15 to the second frame 12 and the second suspension member 32, the connection between the second suspension member 32 and the second frame 12 can be facilitated, the installation of the second suspension member 32 can be facilitated, the installation efficiency of the second suspension assembly 30 can be improved, the structural strength of the two third sub-frames 121 can be improved, and the overall structural strength of the vehicle frame body 10 can be improved.
[0048] According to some embodiments of the present invention, as Figure 2 shown, the first suspension assembly 20 includes: a bushing 21 and a first mounting bracket 22; the first mounting bracket 22 is formed with a mounting groove, and the bushing 21 is fitted with the mounting groove.
[0049] The first mounting bracket 22 is arranged above the third sub-frame 121 along the length direction A of the vehicle frame body 10 and is spaced from the third sub-frame 121 along the height direction C of the vehicle frame body 10. The first mounting bracket 22 is formed with an arc-shaped mounting groove, and the bushing 21 is fitted in the mounting groove. And the bushing 21 is in interference fit with the first mounting bracket 22. The bushing 21 is composed of an inner tube, a rubber body, and an outer tube, and the rubber body is vulcanized with the inner tube and the outer tube to form the bushing 21.
[0050] In this embodiment, there are two first suspension assemblies 20. The two first suspension assemblies 20 are respectively connected to the two third sub-frames 121, and the two first suspension assemblies 20 are flush along the width direction B of the vehicle frame body 10. And they are respectively arranged above the two third sub-frames 121.
[0051] Thus, the first mounting bracket 22 is formed with a mounting groove, which can facilitate the cooperation between the bushing 21 and the first mounting bracket 22, optimize the structure of the first mounting bracket 22, and then install the bushing 21 and the first mounting bracket 22 into the third sub-frame 121 after cooperation, improving the installation efficiency and facilitating the integrated and modular design of the vehicle frame 100. After the vehicle frame 100 is connected to the powertrain 200, the first suspension assembly 20 can attenuate the vibration transmitted from the powertrain 200 to the second frame 12.
[0052] According to some embodiments of the present utility model, as Figure 2 shown, the frame body 10 includes: a second mounting bracket 14, the second mounting bracket 14 is connected to the second frame 12 and is disposed on a side of the second frame 12 facing the first frame 11, a bushing 21 is disposed between the first mounting bracket 22 and the second mounting bracket 14, and the first mounting bracket 22 and the second mounting bracket 14 are connected.
[0053] The second mounting bracket 14 is disposed on the third sub-frame 121 along the length direction A of the frame body 10. The second mounting bracket 14 is provided with a groove opposite to the mounting groove of the first mounting bracket 22, facilitating the connection of the first suspension assembly 20 to the first mounting bracket 22 and the second mounting bracket 14. For the convenience of describing this embodiment, the mounting groove formed on the first mounting bracket 22 is the first mounting groove, the second mounting groove is formed on the second mounting bracket 14, one end of the second mounting groove away from the first mounting groove is connected to the third sub-frame 121, both ends of the second mounting bracket 14 along the length direction A of the frame body 10 are respectively connected to both ends of the first mounting bracket 22 along the length direction A of the frame body 10, the bushing 21 is disposed in the first mounting groove and the second mounting groove, and the bushing 21 is in interference fit with the second mounting bracket 14.
[0054] In this embodiment, the frame body 10 includes two identical second mounting brackets 14, and two identical second mounting brackets 14 are respectively disposed on the two third sub-frames 121 along the height direction C of the frame body 10.
[0055] Thus, the bushing 21 is disposed between the first mounting bracket 22 and the second mounting bracket 14, and the first mounting bracket 22 and the second mounting bracket 14 are connected to each other to fix the bushing 21. Vibration is transmitted to the first mounting bracket 22 and the second mounting bracket 14 through the first bushing 21 and then transmitted to the second frame 12, realizing the first attenuation of the vibration transmitted to the frame 100. Finally, the second attenuation of the vibration between the first frame 11 and the second frame 12 is realized at the second suspension assembly 30, so that the frame 100 has a better vibration damping effect.
[0056] According to some embodiments of the present utility model, as Figure 2As shown, the vehicle frame 100 further includes a second connecting plate 41. The second connecting plate 41 is connected to the first vehicle frame 11 at the other end of the vehicle frame body 10 away from the connection between the first vehicle frame 11 and the second vehicle frame 12. The second connecting plate 41 and the first connecting plate 40 are disposed on both sides of the second sub-vehicle frame 112 along the length direction A of the vehicle frame body 10. There are two second suspension assemblies 30, and the distance between the centers of the two second suspension assemblies 30 is respectively equal to the distance from the centers of the two second suspension assemblies 30 to the center of the second connecting plate 41. That is, the two first connecting plates 40 and one second connecting plate 41 are arranged in a triangle on the second sub-vehicle frame 112, and the second connecting plate 41 is adapted to be connected to the end of the power assembly 200 away from the connection between the first vehicle frame 11 and the second vehicle frame 12.
[0057] One end of the second connecting plate 41 is connected to the side of the second sub-vehicle frame 112 adjacent to the reinforcing member 13, and the other end of the second connecting plate 41 extends in the direction away from the second sub-vehicle frame 112 along the length direction A of the vehicle frame body 10.

The two second suspension assemblies 30 are spaced apart along the width direction B of the vehicle frame body 10 and are respectively connected to the two first connecting plates 40. The distance between the two second suspension assemblies 30 is equal to the distance between the first suspension assembly 20 and the second connecting plate 41, and the distances from the two second suspension assemblies 30 to the adjacent second connecting plate 41 are respectively equal. That is, an equilateral triangle is formed by the centers of the two second suspension assemblies 30 and the second connecting plate 41.
[0059] Thus, the distance between the centers of the two second suspension assemblies 30 is respectively equal to the distance from the centers of the two second suspension assemblies 30 to the center of the second connecting plate 41, which can facilitate the connection between the power assembly 200 and the vehicle frame 100, improve the stability of the second connecting plate 41 and the first connecting plate 40 disposed on the second sub-vehicle frame 112, improve the structural stiffness of the second connecting plate 41, and reduce the transmission of vibration.
[0060] According to some embodiments of the present invention, as Figure 1 and Figure 2 shown, there are two first suspension assemblies 20, and the distances between the centers of the two first suspension assemblies 20 and the centers of the adjacent second suspension assemblies 30 are respectively equal.
[0061] In this embodiment, the vehicle frame body 10 includes two identical first suspension components 20, which are respectively arranged on two third sub-frame bodies 121 along the height direction C of the vehicle frame body 10, and the two first suspension components 20 are adapted to be connected to both ends of the powertrain 200 along the width direction B of the vehicle frame body 10. The distance from the center of the first suspension component 20 on one side of the vehicle frame body 10 in the width direction B to the center of the second suspension component 30 is equal to the distance from the center of the first suspension component 20 on the other side of the vehicle frame body 10 in the length direction A to the center of the second suspension component 30. That is, the two first suspension components 20 and the two second suspension components 30 form an isosceles trapezoid.
[0062] Therefore, the distances between the centers of the two first suspension components 20 and the centers of the adjacent second suspension components 30 are equal, which can avoid the deformation of the first vehicle frame 11 and the second vehicle frame 12, improve the connection strength and stability between the powertrain 200 and the vehicle frame body 10, and reduce the vibration transmission between the powertrain 200 and the vehicle frame body 10.
[0063] According to the vehicle of the second aspect embodiment of the present utility model, as Figure 1 and Figure 3 shown, it includes: a powertrain 200 and a vehicle frame 100; the vehicle frame 100 is any one of the vehicle frames 100 in the above first aspect embodiment, one end of the powertrain 200 is connected to the second connection plate 41 of the vehicle frame 100, and the other end of the powertrain 200 is connected to the first suspension component 20 of the vehicle frame 100.
[0064] That is, one end of the powertrain 200 along the length direction A of the vehicle frame body 10 is rigidly connected to the second connection plate 41, and both ends of the powertrain 200 along the width direction B of the vehicle frame body 10 are flexibly connected to the two first suspension components 20. For example, one end of the second connection plate 41 far from the second vehicle frame 12 penetrates through the other end along the height direction C of the vehicle frame body 10 to form a through hole, and a bolt passes through the through hole to be connected to one end of the powertrain 200 along the length direction A of the vehicle frame body 10. The distance between the connection center point of the powertrain 200 and the second connection plate 41 and the two first suspension components 20 is equal. The center of the second connection plate 41 and the centers of the two first suspension components 20 are arranged in a triangle, which can improve the stability and reliability of the vehicle frame 100. It can facilitate the connection between the powertrain 200 and the vehicle frame 100, better restrict the centroid displacement of the powertrain 200, and reduce the transmission of vibration between the powertrain 200 and the vehicle frame body 10.
[0065] Thus, when the powertrain 200 is in the working state, the vibration generated by the powertrain 200 is first attenuated by the two first mounting components 20, then transmitted to the two second mounting components 30 through the first vehicle frame 11 and the second vehicle frame 12 for attenuation. Finally, the two second mounting parts 34 in the two second mounting components 30 repel each other with the same polarity, which can cancel out a part of the vibration, reduce the transmission of the vibration, improve the vibration isolation performance, and enhance the stability during the vehicle operation, so that the vehicle has a good NVH perception experience.
