[0002] The rear bumper is an important safety device that absorbs and mitigates external impact and protects the rear part of the vehicle. As consumers' quality requirements for the vehicle's rear bumper assembly become increasingly higher, the structural design of the vehicle's rear bumper bracket is becoming increasingly important.

[0003] The rear bumper brackets of existing vehicles are usually large and long, and are generally cantilever structures with empty space on all sides. This type of rear bumper bracket has weak overall strength and is easily deformed during assembly and transportation, which not only makes it difficult to assemble the rear bumper normally, but also causes the position of the rear bumper to deviate after assembly.

[0015] Beneficial effects: The reinforcement component has a simple structure and occupies a small space as a whole, which can effectively reduce the impact of installing the reinforcement component on other components at the bottom of the rear floor assembly of the vehicle.

[0045] Combine the following Figures 1 to 10 , describing an embodiment of the present application.

[0046] According to an embodiment of the present application, on the one hand, a supporting device is provided for supporting a mounting bracket 201, wherein the mounting bracket 201 is connected to a rear skirt assembly 2 of a vehicle, and the supporting device comprises: a reinforcing component 1 having a first connecting section 101 for being assembled and connected to a rear floor assembly 3 of the vehicle, and a second connecting section 102 for being assembled and connected to the mounting bracket 201, wherein the reinforcing component 1, the rear floor assembly 3, the rear skirt assembly 2 and the mounting bracket 201 are suitable for being connected and enclosed to form a frame supporting structure.

[0047] The embodiment of the present application provides a supporting device, in which a reinforcing component 1 is arranged on the rear floor assembly 3, and is connected to the mounting bracket 201 through the second connecting section 102 of the reinforcing component 1, so that an effective frame supporting structure can be formed between the rear floor assembly 3 and the reinforcing component 1. The reliable stability of the frame structure can effectively overcome the problem of poor stability of the rear bumper bracket as a cantilever structure, and effectively improve the overall structural strength and stability of the reinforcing component 1, which can reduce the deformation of the mounting bracket 201 caused by external forces during the assembly process, and at the same time, can reliably support the mounting bracket 201 during long-term use of the vehicle, thereby improving the reliability of the assembly process of the rear bumper 4 and the collision performance of the rear of the vehicle, effectively solving the problem that the existing rear bumper bracket structure is weak in strength and cannot meet the use requirements.

[0048] It should be noted that the mounting bracket 201 is used to mount the rear bumper 4 of the vehicle. The rear skirt assembly 2, the rear floor assembly 3 and the rear bumper 4 are all components of the rear portion of the vehicle in the length direction. In this embodiment, the length direction of the vehicle refers to Figure 2 The arrow in the middle refers to the "length direction", and the width direction of the vehicle refers to Figure 2 The arrow in the middle indicates the "width direction", and the height direction of the vehicle refers to Figure 2 The arrow in the middle points to the "height direction".

[0049] In addition, during the long-term service of the vehicle, the mounting bracket 201 will continue to be subjected to forces in different directions on bumpy roads and during acceleration and deceleration. The provision of the reinforcing component 1 can effectively improve the stability of the mounting bracket 201 and extend the service life of the mounting bracket 201.

[0050] Among them, it should be noted that there is no limitation on the number and specific structural form of the mounting bracket 201. The number of the mounting bracket 201 can be two, three, four or more. The mounting bracket 201 can be a rod-shaped structure or a plate-shaped structure. The mounting bracket 201 can extend vertically or extend in the unloaded direction relative to the vertical direction and have a bent or curved part. The number and specific structure of the mounting bracket 201 can be flexibly selected according to needs.

[0051] Specifically, Figure 6 As shown, the reinforcement component 1, the rear floor assembly 3, and the rear skirt assembly 2 are connected and enclosed in sequence to form a support structure with a support cavity inside. The support cavity as a whole extends along the width direction of the vehicle, which can effectively improve the bending resistance of the local position and also has better collision performance. The support cavity absorbs part of the kinetic energy when it is compressed.

[0052] Furthermore, compared to changing the structure or material of the mounting bracket 201 itself, after changing the structure or material of the mounting bracket 201 itself, the structures that usually cooperate with it, such as the rear bumper 4 and part of the rear skirt assembly 2, also need to change the material or structure to be able to adapt to the changed mounting bracket 201. The support device of this embodiment can be directly applied to the existing rear floor assembly 3 and the mounting bracket 201, and the structural strength of the mounting bracket 201 can be directly improved without making major changes to the original structure, which has the advantages of flexible application and easy installation.

[0053] In this embodiment, one end of the mounting bracket 201 forms a mounting section 2011 for mounting the rear bumper 4, and the second connecting section 102 is used to connect to the mounting section 2011. This connection form can effectively support the entire mounting bracket 201 and prevent the unsupported end of the mounting bracket 201 from being bent due to shear force.

[0054] Specifically, the mounting bracket 201 is usually located at the bottom of the rear skirt assembly 2 and is a cantilever structure. The length of the mounting bracket 201 is generally 150 mm to 200 mm. In order to facilitate connection with the rear bumper 4, the lower end of the mounting bracket 201 is usually bent to form a mounting section 2011. The mounting bracket 201 is generally close to an "L" shape. Figure 3 As shown, the second connecting section 102 supports the mounting section 2011 upward along the height direction of the vehicle from the bottom of the mounting section 2011, which can effectively improve the bearing capacity of the mounting section 2011.

[0055] In this embodiment, one side of the second connecting section 102 cooperates with the mounting section 2011, and the other side of the second connecting section 102 cooperates with the rear bumper 4. The mounting section 2011, the second connecting section 102 and the rear bumper 4 are suitable for being assembled and connected in sequence. The second connecting section 102 of this connection method can improve the local structural strength of the mounting section 2011 while supporting the mounting bracket 201, so that the reinforcement component 1 can jointly bear the rear bumper 4 with the mounting bracket 201, thereby improving the load-bearing reliability.

[0056] It should be noted that the connection sequence of the installation section 2011, the second connection section 102 and the rear bumper 4 can be flexibly changed according to needs, and the form of connecting the installation section 2011, the second connection section 102 and the rear bumper 4 in sequence is the technical solution with better reliability.

[0057] Among them, there is no limitation on the connection method between the installation section 2011, the second connecting section 102 and the various components in the rear bumper 4. They can be connected by welding, fastening components, etc. The installation section 2011, the second connecting section 102 and the rear bumper 4 can be connected in pairs or all three can be connected at the same time.

[0058] In this embodiment, the rear bumper 4, the second connecting section 102 and the mounting section 2011 are connected in sequence through the first connecting member 5, and the corresponding positions of the mounting section 2011, the second connecting section 102 and the rear bumper 4 are provided with through holes 1021 for the first connecting member 5 to pass through. The rear bumper 4, the second connecting section 102 and the mounting section 2011 can be connected simultaneously through a single first connecting member 5. The connection method is simple and reliable, light in weight, fewer installation steps are required for connecting the three, and the integrity after connection is better.

[0059] There is no limitation on the specific form of the first connecting member 5 , which may be a bolt and nut, a connecting pin, etc., preferably a bolt and nut.

[0060] In the related art, in order to ensure the convenience of disassembly and assembly, the mounting section 2011 and the rear bumper 4 are usually connected by a combination of bolts and nuts. Since the rear bumper 4, the second connecting section 102 and the mounting section 2011 of this embodiment are connected simultaneously by the first connecting member 5, the reinforcement component 1 of this embodiment can be directly assembled and connected with the mounting section 2011 and the rear bumper 4 after the through hole 1021 is opened, which effectively avoids the need to make major modifications to the original structure.

[0061] Specifically, Figure 6 As shown, along the height direction of the vehicle from top to bottom, there are the installation section 2011, the second connecting section 102 and the rear bumper 4 in sequence. The bolts in the first connecting member 5 pass through the rear bumper 4, the second connecting section 102 and the installation section 2011 in sequence from bottom to top and are locked and connected with the corresponding nuts in the first connecting member 5. This bolt threading method makes the assembly operation more convenient.

[0062] In this embodiment, the reinforcement component 1 also includes a support section 103, the first connecting section 101 is connected to the second connecting section 102 through the support section 103, the first connecting section 101 is connected to the bottom surface of the rear floor assembly 3, the part of the support section 103 close to the first connecting section 101 extends along the bottom surface of the rear floor assembly 3, and the part of the support section 103 away from the first connecting section 101 is bent downward and connected to the second connecting section 102, so as to form an avoidance space 1031 under the support section 103 for avoiding other components inside the vehicle. The reinforcement component 1 has a simple structure and occupies a small space as a whole, which can effectively reduce the impact of the installation of the reinforcement component 1 on other components at the bottom of the rear floor assembly 3 of the vehicle.

[0063] The bottom surface of the rear floor assembly 3 is the lower surface in the height direction of the vehicle, and the downward bending is bending toward the lower surface in the height direction of the vehicle.

[0064] Specifically, if Figures 3 to 6 As shown, the reinforcement component 1 is generally close to a "Z" shape and is a plate-like structure. This type of reinforcement component 1 is light in weight and easy to process and manufacture, and can reduce the impact on the weight of the entire vehicle.

[0065] In this embodiment, the reinforcement component 1 includes multiple reinforcement brackets, each reinforcement bracket has a first connecting section 101 and a second connecting section 102. Multiple mounting brackets 201 are connected to the rear skirt assembly 2. The rear floor assembly 3 is connected to the corresponding mounting brackets 201 through each reinforcement bracket. The reinforcement component 1 is a multiple split reinforcement bracket. Compared with an independent integral structure, the manufacturing difficulty and manufacturing cost of the reinforcement component 1 itself can be effectively reduced, and the weight of the reinforcement component 1 can also be reduced.

[0066] Specifically, compared with an integrated reinforcement bracket, each of the multiple split reinforcement brackets is smaller in size and the connecting portion between two adjacent reinforcement brackets can be omitted, which can further reduce manufacturing difficulty and processing costs.

[0067] Furthermore, there is no specific limitation on the number of reinforcing components 1, and the number of reinforcing components 1 may correspond to the number of mounting brackets 201. The rear floor assembly 3 is connected to a corresponding mounting bracket 201 via a reinforcing bracket. The number of reinforcing components 1 may be less than the number of mounting brackets 201, and the rear floor assembly 3 may be connected to one or more mounting brackets 201 via a reinforcing bracket, as long as each mounting bracket 201 can be supported.

[0068] In this embodiment, the reinforcement component 1 includes a first reinforcement bracket 104 and a second reinforcement bracket 105. The first reinforcement bracket 104 is located on the right side of the rear floor assembly 3 in the width direction, and the second reinforcement bracket 105 is located on the left side of the rear floor assembly 3 in the width direction. The rear floor assembly 3 is connected to the mounting bracket 201 on the right side of its own width direction through the first reinforcement bracket 104, and the rear floor assembly 3 is connected to the mounting bracket 201 on the right side of its own width direction through the second reinforcement bracket 105. This form of reinforcement component 1 effectively reduces the number of components while ensuring that its own structural strength meets the requirements and is easy to manufacture.

[0069] It should be noted that, when there is only one mounting bracket 201 on the left or right side of the rear floor assembly 3 in the width direction, the corresponding one of the first reinforcing bracket 104 and the second reinforcing bracket 105 is connected thereto, and the other one of the first reinforcing bracket 104 and the second reinforcing bracket 105 is connected to the remaining mounting bracket 201 at the same time.

[0070] Specifically, Figure 1 , Figure 5 , Figure 7 as well as Figure 8 As shown, multiple mounting brackets 201 are arranged at intervals along the width direction of the vehicle, and the first reinforcing bracket 104 and the second reinforcing bracket 105 are also arranged in sequence along the width direction of the vehicle. The first reinforcing bracket 104 is connected to the mounting bracket 201 close to the edge of the width direction of the vehicle, and the second reinforcing bracket 105 is respectively connected to the remaining mounting brackets 201.

[0071] Furthermore, if Figure 4 , Figure 7 as well as Figure 8 As shown, the projection of the first reinforcing bracket 104 on the horizontal plane extends along the width direction of the vehicle as a whole, and the projection of the second reinforcing bracket 105 on the horizontal plane extends along the length direction of the vehicle as a whole. This form of the first reinforcing bracket 104 and the second reinforcing bracket 105 has a relatively simple structure, and there is a large interval between the first reinforcing bracket 104 and the second reinforcing bracket 105, which can provide operating space for the assembly of each connection point.

[0072] In this embodiment, the reinforcement bracket is connected to the rear floor assembly 3 via a plurality of second connecting members 6 . The connection method is simple and reliable. The plurality of second connecting members 6 can ensure the connection strength between the reinforcement bracket and the rear floor assembly 3 .

[0073] It can be understood that, as an alternative implementation, the reinforcement bracket can also be connected to the rear floor assembly 3 by welding or other connection methods.

[0074] Specifically, Figure 7 and Figure 8As shown, the first reinforcement bracket 104 and the second reinforcement bracket 105 are respectively connected to corresponding parts of the rear floor assembly 3, and a plurality of connection holes 1011 for the second connection member 6 to pass through are arranged at intervals along their own contours.

[0075] There is no limitation on the specific type of the second connecting member 6 , and it may be a bolt, a nut, a connecting screw, etc., which can be flexibly selected.

[0076] In this embodiment, the first connecting section 101 of the first reinforcing bracket 104 is connected to the first connecting section 101 of the adjacent second reinforcing bracket 105 to connect the first reinforcing bracket 104 and the second reinforcing bracket 105 into one body and form a concave structure, such as Figure 3 As shown, the first reinforcing bracket 104 is connected to the adjacent side of the rear floor assembly 3 corresponding to the first reinforcing bracket 104. The concave structure formed at the connection position has more connection points with the rear floor assembly 3 at local positions compared to the "mouth"-shaped structure formed by a single integral reinforcing bracket. The connection position between the concave structure and the rear floor assembly 3 can transmit force through the first reinforcing bracket 104 or through the second reinforcing bracket 105, forming multiple force transmission paths, thereby improving the stability and structural strength of the formed support structure, and effectively avoiding the situation where deformation is easy to occur due to the excessive overall width of the reinforcing component.

[0077] Among them, the notch formed in the middle of the concave structure can also be used as a refuge space for the wiring harness, which can further save the layout space in the vehicle.

[0078] It should be noted that the concave structure refers to a depression formed along the lower right and upward direction of the height direction of the vehicle close to the rear floor assembly 3 .

[0079] According to an embodiment of the present application, on the other hand, a vehicle is provided, which includes: a rear bumper 4, a rear floor assembly 3, a rear skirt assembly 2 and the above-mentioned supporting device, the rear skirt assembly 2 is assembled and connected to the rear floor assembly 3, the rear skirt assembly 2 has a plurality of mounting brackets 201 arranged at intervals along its own width direction, the mounting brackets 201 are used to install the rear bumper 4, and the supporting device is respectively connected to the rear floor assembly 3 and the mounting brackets 201 to support the mounting brackets 201.

[0080] In this embodiment, the rear skirt assembly 2 includes a skirt body 202, and a plurality of mounting brackets 201 are spaced apart on the lower side of the skirt body 202. The interior of the skirt body 202 has a cavity 2021. This form of skirt body 202 has stronger bending resistance and lighter weight.

[0081] Specifically, the lower end of the skirt body 202 partially overlaps with the upper end of the mounting bracket 201, and the two are overlapped and connected, and the connection form is simple and reliable.

[0082] In this embodiment, the vehicle also includes a rear longitudinal beam assembly 7, which is arranged on both sides of the width direction of the rear floor assembly 3, the rear longitudinal beam assembly 7 is connected to the rear floor assembly 3, and the rear skirt assembly 2 is respectively connected to the rear longitudinal beam assembly 7 and the rear floor assembly 3. The rear skirt assembly 2, the rear longitudinal beam assembly 7 and the rear floor assembly 3 form a frame structure. This form of structure has strong structural reliability and high strength, which can improve the collision performance of the rear of the vehicle. At the same time, it can also form an effective structural support for the installation of the support device and the installation of the mounting bracket 201.

[0083] Specifically, if Figure 6 As shown, the skirt panel body 202 is overlapped and connected with the rear floor assembly 3, the rear floor assembly 3 is overlapped and connected with the supporting device, the supporting device is overlapped and connected with the mounting bracket 201, and the mounting bracket 201 is overlapped and connected with the skirt panel body 202. The four components are overlapped and connected in sequence to form a cavity structure that is approximately "mouth" shaped, thereby improving the overall strength of the local position and improving the collision performance of the rear of the vehicle.

[0084] Among them, the rear longitudinal beam assembly 7 is preferably an alloy extruded profile, and the rear floor assembly 3 is preferably a sheet metal structure.

[0085] 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.
