[0045] As passengers' requirements for vehicle NVH (Noise, Vibration, Harshness) performance continue to increase, the stiffness of the mounting points between the subframe and the body needs to be strengthened in the early stages of vehicle development.

[0046] However, the existing front subframe and body are installed in a single-cavity structure, which has the defect of insufficient local structural rigidity, and is prone to bring NVH risks to the IPI (Input Point Inertance) and NTF (Noise Transfer Function) of other chassis attachment points on the front subframe, resulting in greater vibration and noise in the car and a poor driving experience.

[0047] The present application embodiment provides a vehicle. Figure 1 For a vehicle, a body 12 is generally provided. The body 12 is composed of a plurality of load-bearing elements and sheet metal parts connected thereto, and forms a rigid space structure. The body 12 is used to carry people and cargo, and is the installation base of the body parts.

[0048] In addition, the vehicle is generally provided with a subframe. The subframe can be regarded as the framework of the front and rear axles, which is used to block vibration and noise. The subframe usually includes a front subframe 11 and a rear subframe.

[0049] The vehicle provided in the embodiment of the present application refers to Figure 1 In addition to the above-mentioned vehicle body 12 and subframe, a pair of front subframe mounting structures are also provided. The pair of front subframe mounting structures are mounted on the vehicle body 12 and are used to connect the vehicle body 12 and the front subframe 11. The opposite ends of the front subframe 11 are respectively connected to a front subframe mounting structure, so as to be mounted on the vehicle body 12. In order to facilitate the installation of the front subframe 11 and improve the rigidity of the mounting point, refer to Figure 1 , a pair of front subframe mounting structures form an axisymmetric structure.

[0050] Reference Figure 2 and Figure 5 The front subframe mounting structure mainly includes: a mounting plate 1, a longitudinal beam 2 and a support plate 3. The mounting plate 1 is connected to the front subframe 11. The longitudinal beam 2 is connected to a side of the mounting plate 1 away from the front subframe 11, and a first cavity 4 is formed between one side of the longitudinal beam 2 and the mounting plate 1. The support plate 3 is connected to the longitudinal beam 2, and a second cavity 5 is formed between the support plate 3 and the other side opposite to the longitudinal beam 2.

[0051] The embodiment of the present application uses the mounting plate 1 to mount the front sub-frame 11, and the position on the mounting plate 1 connected to the front sub-frame 11 forms a first cavity 4 with one side of the longitudinal beam 2. The other side of the longitudinal beam 2 also forms a second cavity 5 with the support plate 3, that is, the front sub-frame mounting structure uses a double-cavity structure to mount the front sub-frame 11, which improves the rigidity of the mounting point of the front sub-frame 11, effectively reduces the vibration and noise of the vehicle, and provides a good driving experience.

[0052] It should be noted that the vehicle in this application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the car model, the car in this application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other models. Generally, a vehicle is provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.

[0053] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.

[0054] On this basis, refer to Figure 1 , Figure 2 and Figure 5 The embodiment of the present application also provides a front sub-frame mounting structure, which mainly includes: a mounting plate 1, a longitudinal beam 2 and a support plate 3. The mounting plate 1 is connected to the front sub-frame 11. The longitudinal beam 2 is connected to a side of the mounting plate 1 away from the front sub-frame 11, and a first cavity 4 is formed between one side of the longitudinal beam 2 and the mounting plate 1. The support plate 3 is connected to the longitudinal beam 2, and a second cavity 5 is formed between the support plate 3 and the other side opposite to the longitudinal beam 2.

[0055] The front sub-frame mounting structure provided in the embodiment of the present application utilizes a mounting plate 1 to mount a front sub-frame 11. The position on the mounting plate 1 connected to the front sub-frame 11 forms a first cavity 4 with one side of the longitudinal beam 2. The other side of the longitudinal beam 2 also forms a second cavity 5 with the support plate 3. That is, the front sub-frame mounting structure utilizes a dual-cavity structure to mount the front sub-frame 11, thereby improving the stiffness of the mounting point of the front sub-frame 11, effectively reducing the vibration and noise of the vehicle, and providing a good driving experience.

[0056] It should be noted that the embodiment of the present application does not limit the connection relationship between the longitudinal beam 2 and the mounting plate 1 and the support plate 3. A snap-on connection structure, such as a buckle and a slot, can be used to facilitate installation. A fastening connection structure, such as a bolt connection, a welding connection, etc., can also be used for a fastened connection.

[0057] In addition, there is no restriction on the connection relationship between the mounting plate 1 and the front sub-frame 11, and any existing connection structure can be selected as needed, such as welding, which has a high connection strength. In order to further improve the connection strength between the mounting plate 1 and the front sub-frame 11, the mounting plate 1 can be connected to the front sub-frame 11 through multiple mounting points. The specific number can be selected and set according to actual needs, and the embodiment of the present application does not impose too many restrictions on this.

[0058] In some embodiments of the present application, reference Figures 2 to 4 As shown, the longitudinal beam 2 mainly includes: a bottom plate 201 and a pair of side plates 202. The bottom plate 201 is connected to the mounting plate 1 and forms a first cavity 4 with the mounting plate 1. The pair of side plates 202 are arranged opposite to each other and are respectively connected to opposite ends of the bottom plate 201. The support plate 3 is arranged between the pair of side plates 202, and is arranged opposite to the bottom plate 201 and forms a second cavity 5.

[0059] Specifically, the bottom plate 201 and the pair of side plates 202 are integrally formed, and installation is omitted for ease of use. The bottom surface of the bottom plate 201 is welded and fixed to the mounting plate 1 to improve the connection strength between the mounting plate 1 and the bottom plate 201. The opposite ends of the mounting plate 1 also extend and adhere to the outer sides of the pair of side plates 202 to improve the connection strength between the mounting plate 1 and the longitudinal beam 2. Similarly, the support plate 3 is also welded and fixed to the side plates 202.

[0060] In some embodiments of the present application, reference Figures 2 to 6 The front sub-frame mounting structure further includes a fastener 6. The fastener 6 is connected to the front sub-frame 11, and passes through the first cavity 4 and the second cavity 5 to be connected to the mounting plate 1, the bottom plate 201 and the support plate 3 respectively.

[0061] Specifically, refer to Figure 5 and Figure 6 The fastener 6 can be a threaded tube. The lower end of the threaded tube is first fixed to the front subframe 11. The mounting plate 1 is inserted into the slot on the middle side wall of the threaded tube to achieve fixation with the threaded tube. The upper end of the threaded tube passes through the first cavity 4 and the second cavity 5 respectively, and is connected to the bottom plate 201 and the support plate 3 in turn.

[0062] Further, in some embodiments of the present application, referring to Figure 6 , the tube wall of the fastener 6 is welded to the support plate 3 and forms a first circle of welding. The support plate 3 is provided with a second through hole for the fastener 6 to pass through, that is, the fastener 6 forms a first circle of welding at the second through hole. Figure 6 As shown in A in FIG. 2 . The tube wall of the fastener 6 is also welded to the longitudinal beam 2 to form a second circle of welding. The bottom plate 201 is provided with a first through hole for the fastener 6 to pass through, that is, the fastener 6 forms a second circle of welding at the first through hole. The second circle of welding is as shown in FIG. Figure 6That is, the fastener 6 forms two circles of protective welding with the longitudinal beam 2 and the support plate 3 from bottom to top, respectively. Compared with the traditional single-cavity structure with only one circle of protective welding, the Z-direction stiffness of the front subframe 11 installation point can be effectively improved. The upper and lower directions referred to in the embodiment of the present application are as follows: Figure 6 shown.

[0063] Further, in some embodiments of the present application, referring to Figures 4 to 6 The diameter of the portion of the fastener 6 located in the first cavity 4 gradually decreases from the mounting plate 1 to the bottom plate 201 , that is, it is wider at the bottom and narrower at the top, so as to improve the connection tightness between the fastener 6 and the longitudinal beam 2 .

[0064] Specifically, the outer diameter of the fastener 6 at the lower end of the first cavity 4 is greater than the diameter of the first through hole, and the outer diameter of the fastener 6 at the upper end of the first cavity 4 is less than the diameter of the first through hole, so as to limit the length of the portion of the fastener 6 passing through the first cavity 4. In addition, the portion of the fastener 6 located in the second cavity 5 is a cylindrical tube so that the fastener 6 can pass through the second through hole.

[0065] In some embodiments of the present application, reference Figures 2 to 5 The front subframe mounting structure further comprises a connecting plate 7. The connecting plate 7 is adapted to be connected to the vehicle body 12. Specifically, the connecting plate 7 is connected to the side door sill, and the connecting plate 7 is also connected to the mounting plate 1 and the bottom plate 201 respectively.

[0066] Further, in some embodiments of the present application, referring to Figure 3 and Figure 4 The connecting plate 7 includes a first connecting plate 701 and a second connecting plate 702 connected at an angle. The angle between the first connecting plate 701 and the second connecting plate 702 can be selected and set according to actual needs, and the embodiment of the present application does not impose too many restrictions on this. The longitudinal beam 2 is arranged between the first connecting plate 701 and the second connecting plate 702, and forms a triangular structure with the first connecting plate 701 and the second connecting plate 702 to improve the structural strength of the longitudinal beam 2.

[0067] In addition, refer to Figure 7 The second connecting plate 702 partially overlaps with the longitudinal beam 2 to form a lap joint structure, which has a larger connection area and better bearing capacity.

[0068] Further, in some embodiments of the present application, referring to Figure 4 and Figure 5 The front subframe mounting structure further includes a first reinforcing plate 8 and a second reinforcing plate 9. The first reinforcing plate 8 is disposed on a side surface of the second connecting plate 702 close to the first connecting plate 701 to share the load of the longitudinal beam 2 on the second connecting plate 702 and enhance the supporting capacity of the second connecting plate 702. The shape of the first reinforcing plate 8 is adapted to the upper surface of the second connecting plate 702.

[0069] In addition, refer to Figure 7 The second reinforcing plate 9 is respectively connected to the first connecting plate 701, the first reinforcing plate 8 and the longitudinal beam 2, so as to improve the Y-direction lateral rigidity of the mounting point of the front subframe 11. The second reinforcing plate 9 can adopt a door-type structure, wherein two adjacent ends are respectively connected to the first connecting plate 701 and the first reinforcing plate 8, and the other end opposite to the first connecting plate 701 is connected to the longitudinal beam 2.

[0070] Furthermore, in some embodiments of the present application, the second reinforcing plate 9 forms a multi-section protective weld with the first connecting plate 701 , the first reinforcing plate 8 and the longitudinal beam 2 to improve the Y-direction lateral stiffness of the mounting point of the front subframe 11 .

[0071] For example, Figure 8 As shown in C in FIG. 1 , the second reinforcing plate 9 and the first connecting plate 701 form a three-stage protective weld. Figure 8 As shown in D in FIG. 1 , the second reinforcing plate 9 and the first reinforcing plate 8 form two sections of protective welding. Figure 8 As shown in E in FIG. 1 , the second reinforcing plate 9 forms a two-stage protective weld with the longitudinal beam 2. That is, the second reinforcing plate 9 forms a seven-stage protective weld with the first connecting plate 701, the first reinforcing plate 8 and the longitudinal beam 2. The seven-stage protective weld can significantly improve the Y-direction lateral stiffness of the mounting point of the front subframe 11.

[0072] It is understandable that in some other embodiments, the second reinforcing plate 9 and the first connecting plate 701, the first reinforcing plate 8 and the longitudinal beam 2 may also form other numbers of protective welds, and the specific settings may be selected according to actual needs. For example, the second reinforcing plate 9 and the first reinforcing plate 8 form three-stage protective welds, the second reinforcing plate 9 and the longitudinal beam 2 form three-stage protective welds, etc.

[0073] In order to further improve the lateral stiffness in the X and Y directions of the mounting point of the front subframe 11, in some embodiments of the present application, Figure 1 The front sub-frame mounting structure further includes a connecting member 10. The connecting member 10 is connected to the connecting plate 7 and the front sub-frame 11 respectively.

[0074] In order to facilitate installation and disassembly, the connector 10 is fixedly connected to the bottom surface of the second connecting plate 702 and the front subframe 11 through fixings. Mounting holes are respectively provided at the opposite ends of the connector 10, and the fixing passes through one of the mounting holes and the second connecting plate 702 to achieve a fixed connection between the connector 10 and the second connecting plate 702. The fixing passes through the other mounting hole and the front subframe 11 to achieve a fixed connection between the connector 10 and the front subframe 11. The fixing can be a conventional fixing such as a bolt or a screw. In order to reduce the cost of use, in one possible implementation of the present application, the fixing can be a hexagonal flat head bolt. Correspondingly, the mounting hole can be a threaded hole or a round hole.

[0075] In some embodiments of the present application, reference Figures 2 to 4 The front subframe mounting structure further includes a crossbeam 13. The crossbeam 13 is fixedly connected to the longitudinal beam 2 and the connecting plate 7 to further enhance the mounting point strength of the front subframe 11, thereby further enhancing the driving experience.

[0076] The serial numbers of the embodiments of the present application are only for description and do not represent the advantages and disadvantages of the embodiments. The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application.
