Description

Technical Field

[0001] The utility model relates to the technical field of vehicle structures, in particular to a vehicle rear structure and a vehicle. Background Art

[0002] In the past, cars usually did not have bottom guard plates at the bottom, or only had relatively small local guard plates. This would cause the airflow at the bottom to flow into various parts of the bottom of the car body during driving, thus forming turbulence and increasing the driving resistance of the car during driving. Therefore, for oil cars, driving resistance will increase the fuel consumption of the car. For electric cars, driving resistance will reduce the car's cruising range. Especially for pure electric vehicles, cruising range data is the performance parameter that users are most concerned about. Therefore, if the driving resistance caused by the turbulence at the bottom of the car cannot be reduced, users will have a bad user experience.

[0003] In order to reduce the driving resistance of the car caused by the turbulence at the bottom of the vehicle, one method is to set a lower guard plate at the bottom of the vehicle, set a spoiler on the rear bumper, connect the front end of the spoiler to the rear end of the lower guard plate, and separate the airflow flowing through the spoiler from the car body through the ridges on the spoiler, thereby reducing the driving resistance of the car during driving. However, when using this structure to process the airflow at the bottom of the vehicle, since the spoiler is set on the rear bumper, the tail vortex is closer to the rear of the car, and the vortex at the rear of the car will still affect the car, and the driving resistance cannot be effectively reduced. Therefore, there is an urgent need for a rear vehicle structure and a vehicle, which can make the vortex generated after the airflow is processed away from the rear of the vehicle when processing the airflow at the bottom of the vehicle, reduce the impact on the car, and reduce driving resistance. Utility Model Content

[0004] The present application provides a vehicle rear structure and a vehicle, which can make the tail vortex away from the tail of the vehicle when processing the airflow at the bottom of the vehicle, reduce the impact on the car, and reduce driving resistance.

[0005] The first aspect of the present application provides a vehicle rear structure, comprising: a rear bumper; a lower guard plate, the lower guard plate comprising a first main body portion and a connecting portion, the first main body portion being located at the bottom of the vehicle and extending toward the rear of the vehicle, the connecting portion connecting the rear end of the first main body portion and the rear bumper; and also comprising a spoiler, the spoiler being fixedly connected to the lower guard plate, at least a portion of the spoiler extending rearward from the rear end of the first main body portion.

[0006] With the above structure, since at least a portion of the spoiler extends backward from the rear end of the first main body, the spoiler can process the airflow after the airflow at the bottom of the vehicle flows through the first main body and guide the airflow to the rear. Since the first main body of the lower guard plate is connected to the rear bumper through the connecting portion, that is, the rear end of the first main body is far away from the rear bumper, the airflow processed by the spoiler is far away from the rear bumper and the rear of the vehicle. Therefore, the vortex generated after the airflow is processed by the spoiler extending backward can be kept away from the rear of the vehicle, reducing the impact on the vehicle and reducing the driving resistance.

[0007] As a possible implementation manner of the first aspect, a lower surface of at least a portion of the spoiler extending backward from the rear end of the first main body is flush with a lower surface of the first main body.

[0008] By adopting the above structure, by making the lower surface of at least a portion of the spoiler extending backward from the rear end of the first main body flush with the lower surface of the first main body, the airflow can be smoother when passing between the lower surface of the first main body and the lower surface of the spoiler without generating turbulence, thereby reducing the impact on the vehicle and reducing driving resistance.

[0009] As a possible implementation of the first aspect, the spoiler includes a second main body portion and a mounting portion, the mounting portion is fixedly connected to the lower guard plate, the second main body portion extends backward from the rear end of the first main body portion, and / or the lower surface of the second main body portion is flush with the lower surface of the first main body portion.

[0010] With the above structure, the spoiler can be installed on the lower guard plate through the mounting part, so that the second main body extends backward from the rear end of the first main body. As a result, after the airflow at the bottom of the vehicle flows through the first main body, the second main body processes the airflow, so that the airflow is guided to the rear, and the processed airflow is away from the rear bumper and the rear of the vehicle, thereby reducing the impact on the vehicle and reducing the driving resistance. By making the lower surface of the second main body flush with the lower surface of the first main body, the airflow can be smoother when flowing between the lower surface of the first main body and the lower surface of the second main body, thereby reducing the impact on the vehicle and reducing the driving resistance.

[0011] As a possible implementation manner of the first aspect, the connecting portion at least has an inclined portion extending backward and upward from the rear end of the first main body portion to connect with the rear bumper.

[0012] With the above structure, the connecting part has an inclined portion extending upward, so that the rear end of the first main body can be connected to the rear bumper, so that after the airflow at the bottom of the vehicle flows through the first main body, it will not flow upward toward the rear bumper to form turbulence, but will be guided by the spoiler to flow toward the rear of the car. Therefore, after the spoiler is installed on the first main body, the spoiler and the airflow processed by the spoiler can be kept away from the rear bumper and the rear of the vehicle, thereby reducing the impact on the vehicle and reducing the driving resistance.

[0013] As a possible implementation manner of the first aspect, the spoiler includes a second main body portion and a mounting portion, the second main body portion extends backward from a rear end of the first main body portion, and the mounting portion is fixedly connected to the first main body portion.

[0014] With the above structure, since the second main body extends backward from the rear end of the first main body, the mounting part is fixedly connected to the first main body. That is, the mounting part extends forward from the second main body so as to be fixedly connected to the first main body. Thus, not only can the structure of the spoiler be made simpler, but also the mounting part and the first main body can be easily installed and removed. Such a design allows the first main body and the second main body to form a whole after being connected, which is more conducive to guiding the airflow.

[0015] As a possible implementation manner of the first aspect, the mounting portion is penetrated through the lower guard plate, and the mounting portion is in contact with an upper surface of the first main body.

[0016] With the above structure, the mounting part can be hidden above the lower guard plate by passing through the lower guard plate and fitting with the upper surface of the first main body. The mounting part and the first main body can be fixedly connected in a variety of ways, such as bolt connection, rivet connection, welding, etc., which are not specifically limited here. In this way, the mounting part can be fixedly connected to the first main body without interfering with the airflow under the vehicle, thereby reducing the impact on the car and reducing driving resistance.

[0017] In addition, by allowing the mounting portion to pass through the lower guard plate and fit with the upper surface of the first main body, when installing the spoiler, it is only necessary to make a hole on the lower guard plate at a position corresponding to the mounting portion, or to use the through hole pre-arranged on the lower guard plate to conveniently pass the mounting portion through the upper surface position of the first main body, and the spoiler can be conveniently installed without making major changes to the lower guard plate.

[0018] As a possible implementation of the first aspect, the connecting portion has at least an inclined portion extending backward and upward from the rear end of the first main body portion to be connected to the rear bumper, and a through hole is provided on the inclined portion; the mounting portion includes: a first connecting portion, the first connecting portion extends through the through hole to above the first main body portion, and the first connecting portion is connected to the first main body portion.

[0019] By adopting the above structure, by setting the through hole on the inclined part, the through hole can be avoided from the connection position between the inclined part and the first main body, avoiding affecting the structural strength of the connection position between the inclined part and the first main body, and avoiding the connection position from interfering with the airflow at the bottom of the vehicle. At the same time, since the inclined part is inclined upward, that is, the inclined part is located above the first main body, by setting the through hole on the inclined part, the through hole can be located above the first main body. Therefore, by making the first connecting part extend to the top of the first main body through the through hole, the first connecting part can be completely located above the first main body and the second main body, thereby avoiding interfering with the airflow flowing through the lower surface of the first main body and the second main body, thereby avoiding increasing the driving resistance.

[0020] As a possible implementation of the first aspect, the mounting portion also includes a first connecting hole, which is arranged at the end of the first connecting portion and is used to achieve a fixed connection with the first main body portion; wherein the first connecting portion is bent so that the lower surface of the second main body portion is flush with the lower surface of the first main body portion.

[0021] With the above structure, by setting the first connection hole at the end of the first connection part, the mounting part can be conveniently fixed to the first main body by bolts or rivets. By making the first connection part bend, the first connection part can be conveniently passed through the through hole, and the first connection part can also avoid other structures on the lower guard plate to facilitate the fixed connection between the first connection hole at the end of the first connection part and the first main body. By making the lower surface of the second main body flush with the lower surface of the first main body, the first main body and the second main body can be made smoother, avoiding the increase of driving resistance when the airflow passes through.

[0022] As a possible implementation manner of the first aspect, a plurality of the mounting portions are arranged at intervals along the front end of the second main body portion.

[0023] By adopting the above structure, a plurality of mounting portions are arranged at intervals along the front end of the second main body portion, so that the spoiler can be fixedly connected to the lower guard plate at a plurality of positions, thereby improving the firmness and stability between the spoiler and the lower guard plate.

[0024] As a possible implementation manner of the first aspect, the mounting portion is in contact with a lower surface of the first main body.

[0025] With the above structure, by making the mounting portion fit with the lower surface of the first main body, the installation operation can be performed directly under the vehicle when installing the lower guard plate. As a result, the difficulty of installing the spoiler can be reduced, and the workload of the staff can be reduced. In addition, by making the mounting portion fit with the lower surface of the first main body, the protrusion of the mounting portion from the lower surface of the first main body can be reduced, thereby reducing the impact on the airflow flowing under the first main body, thereby reducing the driving resistance.

[0026] As a possible implementation of the first aspect, a groove is provided on the lower surface of the first main body; the mounting portion includes: a second connecting portion, which is arranged along the front end of the second main body; and at least a portion of the second connecting portion is accommodated in the groove.

[0027] With the above structure, by providing a groove on the lower surface of the first main body, at least a portion of the second connecting portion is accommodated in the groove, thereby reducing the degree to which the mounting portion and the second connecting portion protrude from the lower surface of the first main body, thereby reducing the impact on the airflow flowing through the lower surface of the first main body, and reducing the driving resistance of the vehicle. At the same time, the provision of the groove can also increase the strength of the lower guard plate at the connection position to ensure the overall stability.

[0028] As a possible implementation manner of the first aspect, a reinforcing rib is provided on an upper surface of the second connecting portion, and the reinforcing rib is accommodated in the groove.

[0029] With the above structure, by providing a reinforcing rib on the second connecting portion, the structural strength of the second connecting portion can be improved. By accommodating the reinforcing rib in the groove, the influence of the reinforcing rib on the airflow on the lower surface of the first main body can be reduced, thereby avoiding increasing the driving resistance.

[0030] As a possible implementation manner of the first aspect, the height of the reinforcing rib is set so that after the reinforcing rib abuts against the groove, the lower surface of the second main body portion is flush with the lower surface of the first main body portion.

[0031] By adopting the above structure, by setting the height of the reinforcing rib to abut against the groove, the lower surface of the second main body is flush with the lower surface of the first main body, so that the first main body and the second main body can be smoother and the driving resistance can be avoided from increasing when airflow passes through.

[0032] As a possible implementation manner of the first aspect, the spoiler includes a second main body portion and a mounting portion, the second main body portion extends backward from a rear end of the first main body portion, and the mounting portion is fixedly connected to the inclined portion.

[0033] With the above structure, the inclined portion is inclined upward, so that the inclined portion is located above the first main body. In the present application, the mounting portion is fixedly connected to the inclined portion, so that the mounting portion can be located above the first main body. As a result, the airflow passing through the first main body can flow directly to the second main body without hindrance, and the exposure of the mounting portion from the lower surface of the first main body to affect the airflow and increase the driving resistance can be avoided.

[0034] In addition, by fixing the mounting portion and the inclined portion, the airflow below the first main body portion will not be affected, so the restrictions on the fixing connection method of the mounting portion and the inclined portion can be reduced. Therefore, the mounting portion and the inclined portion can be fixedly connected using a simpler connection method, thereby making the structure simpler.

[0035] As a possible implementation of the first aspect, the mounting portion includes: a third connecting portion, which is inclined along the front end of the second main body portion, and the inclination angle is set so that the third connecting portion fits the outer surface of the inclined portion.

[0036] With the above structure, the inclination angle of the third connection part is set so that the third connection part and the outer surface of the inclined part are in contact with each other, thereby improving the stability of the connection between the third connection part and the inclined part. In addition, the gap between the third connection part and the inclined part can be reduced, thereby reducing the accumulation of dust and other debris between the third connection part and the inclined part.

[0037] As a possible implementation manner of the first aspect, the mounting portion further includes a third connecting hole, wherein the third connecting hole is provided on the third connecting portion and fixedly connected to the inclined portion.

[0038] With the above structure, by providing the third connection hole on the third connection part, the mounting part can be conveniently fixed to the inclined part by means of bolts or rivets.

[0039] As a possible implementation manner of the first aspect, at least one maintenance port is provided on the first main body portion, and / or a detachably connected cover is provided on the maintenance port.

[0040] By adopting the above structure, a maintenance port is provided on the first main body, so that the components above the lower guard plate can be conveniently repaired through the maintenance port. By providing a detachably connected cover on the maintenance port, when the components above the lower guard plate need to be repaired, the maintenance port can be exposed by opening the disassembly cover to facilitate the repair of the components above the lower guard plate without disassembling the entire lower guard plate, thereby improving the maintenance efficiency and reducing the maintenance cost. Under normal circumstances, the maintenance port is closed by installing a cover on the maintenance port, thereby preventing airflow from entering the upper part of the lower guard plate through the maintenance port to avoid increasing driving resistance. At the same time, closing the maintenance port with the cover can also provide protection for the components above the lower guard plate, preventing debris from entering the upper part of the lower guard plate through the maintenance port and causing damage to the components above the lower guard plate.

[0041] A second aspect of the present application provides a vehicle, comprising the vehicle rear structure described in any one of the first aspects of the present application.

[0042] With the above structure, the spoiler is fixed on the lower guard plate, so that at least a part of the spoiler extends backward from the rear end of the first main body. Thus, after the airflow at the bottom of the vehicle flows through the first main body, the spoiler can process the airflow and guide the airflow to the rear of the vehicle. Since the first main body of the lower guard plate is connected to the rear bumper through the connecting part, that is, the rear end of the first main body is far away from the rear bumper, the airflow processed by the spoiler is far away from the rear bumper and the rear of the vehicle. Thus, the vortex generated after the airflow is processed by the spoiler extending backward can be kept away from the rear of the vehicle, reducing the impact on the vehicle and reducing the driving resistance.

[0043] These and other aspects of the present invention will become more apparent from the following description of the embodiment(s). BRIEF DESCRIPTION OF THE DRAWINGS

In addition, in one or more embodiments, the particular features, structures, or characteristics can be combined in any appropriate manner, as will be apparent to one of ordinary skill in the art from this disclosure.

[0062] Below, in conjunction with the accompanying drawings, possible embodiments of the vehicle rear structure in the present application are exemplarily described.

[0063] Figure 1 It is a schematic diagram of the partial orthographic projection structure of the bottom of the vehicle 10 in this application; Figure 2 This is a schematic diagram of the bottom orthographic projection structure of the lower guard plate 300 after the spoiler 500 is installed in Example 1;

[0064] Figure 3 It is a schematic diagram of a partial three-dimensional structure after the spoiler 500 is installed on the lower guard plate 300 in Example 1; Figure 4 is a schematic diagram of the three-dimensional structure of the lower guard plate 300 in Example 1; Figure 5 is a schematic diagram of the three-dimensional structure of the spoiler 500 in Example 1; Figure 6 for Figure 2 A partial cross-sectional structural diagram of the mounting portion 520 of the middle spoiler 500. Figure 1-Figure 6As shown, the rear structure of the vehicle in the present application includes a rear bumper 400, a lower guard plate 300 and a spoiler 500. The lower guard plate 300 includes a first main body portion 310 and a connecting portion 320. The first main body portion 310 is located at the bottom of the vehicle 10 and extends toward the rear of the vehicle 10. The connecting portion 320 connects the rear end of the first main body portion 310 and the rear bumper 400. The spoiler 500 is fixedly connected to the lower guard plate 300, and at least a portion of the spoiler 500 extends backward from the rear end of the first main body portion 310.

[0065] From the above, the spoiler 500 is fixed on the lower guard plate 300 so that at least a part of the spoiler 500 extends backward from the rear end of the first main body 310. Thus, after the airflow at the bottom of the vehicle 10 flows through the first main body 310, the spoiler 500 processes the airflow and guides the airflow to the rear of the vehicle. Since the first main body 310 of the lower guard plate 300 is connected to the rear bumper 400 through the connecting portion 320, that is, the rear end of the first main body 310 is far away from the rear bumper 400, the airflow processed by the spoiler 500 is far away from the rear bumper 400 and the rear of the vehicle 10. Thus, the vortex generated after the airflow processing can be kept away from the rear of the vehicle 10, reducing the impact on the car and reducing the driving resistance.

[0066] In some embodiments, Figure 6 As shown, at least a portion of the lower surface of the spoiler 500 extending backward from the rear end of the first main body 310 is flush with the lower surface of the first main body 310. Thus, by making at least a portion of the lower surface of the spoiler 500 extending backward from the rear end of the first main body 310 flush with the lower surface of the first main body 310, the airflow can be made smoother when passing between the lower surface of the first main body 310 and the lower surface of the spoiler 500, and turbulence will not be generated, thereby reducing the impact on the vehicle 10 and reducing the driving resistance.

[0067] In some embodiments, Figure 5 , Figure 6As shown, the spoiler 500 includes a second main body 510 and a mounting portion 520, the mounting portion 520 is fixedly connected to the lower guard plate 300, the second main body 510 extends backward from the rear end of the first main body 310, and / or the lower surface of the second main body 510 is flush with the lower surface of the first main body 310. Thus, the spoiler 500 can be installed on the lower guard plate 300 through the mounting portion 520, so that the second main body 510 extends backward from the rear end of the first main body 310. Thus, after the airflow at the bottom of the vehicle 10 flows through the first main body 310, the airflow can be processed by the second main body 510, so that the processed airflow is away from the rear bumper 400 and the rear of the vehicle 10, thereby reducing the impact on the vehicle 10 and reducing the driving resistance. By making the lower surface of the second main body 510 flush with the lower surface of the first main body 310, the airflow can be smoother when flowing between the lower surface of the first main body 310 and the lower surface of the second main body 510, and turbulence will not be generated, thereby reducing the impact on the vehicle 10 and reducing driving resistance.

[0068] In some embodiments, Figure 1-Figure 4 , Figure 6 As shown, the connecting portion 320 at least has an inclined portion 321 extending backward and upward from the rear end of the first main body 310 and connected to the rear bumper 400. Thus, by making the connecting portion 320 have the inclined portion 321 extending upward, the rear end of the first main body 310 can be connected to the rear bumper 400, so that after the bottom airflow of the vehicle 10 flows through the first main body 310, it will not flow upward toward the rear bumper 400 to form turbulence, but will be guided by the spoiler 500 to flow toward the rear of the vehicle 10. Thus, after the spoiler 500 is installed on the first main body 310, the spoiler 500 and the airflow processed by the spoiler 500 can be kept away from the rear bumper 400 and the rear of the vehicle 10, thereby reducing the impact on the vehicle 10 and reducing the driving resistance.

[0069] In some embodiments, Figure 6 As shown, the spoiler 500 includes a second main body 510 and a mounting portion 520, wherein the second main body 510 extends backward from the rear end of the first main body 310, and the mounting portion 520 is fixedly connected to the first main body 310. Since the front end of the second main body 510 is connected to the rear end of the first main body 310, the mounting portion 520 is fixedly connected to the first main body 310. That is, the mounting portion 520 extends forward from the second main body 510 so as to be fixedly connected to the first main body 310. Thus, not only can the structure of the spoiler 500 be made simpler, but also the mounting portion 520 and the first main body 310 can be easily installed and removed. Such a design allows the first main body 310 and the second main body 510 to form a whole after being connected, which is more conducive to guiding the bottom airflow of the vehicle 10.

[0070] In some embodiments, Figure 6 As shown, the mounting portion 520 is passed through the lower guard plate 300, and the mounting portion 520 is fitted with the upper surface of the first main body 310. Thus, by passing the mounting portion 520 through the lower guard plate 300 and fitting with the upper surface of the first main body 310 to achieve a fixed connection, the mounting portion 520 can be hidden above the lower guard plate 300. The mounting portion 520 and the first main body 310 can be fixedly connected in a variety of ways, such as bolt connection, rivet connection, welding, etc., which are not specifically limited here. Thus, the mounting portion 520 can be fixedly connected to the first main body 310 without interfering with the airflow below the vehicle 10, so as to reduce the impact on the car and reduce driving resistance.

[0071] In addition, by allowing the mounting portion 520 to pass through the lower guard plate 300 and adhere to the upper surface of the first main body portion 310 to achieve a fixed connection, when installing the spoiler 500, it is only necessary to open a hole on the lower guard plate 300 at a position corresponding to the mounting portion 520, or to use the pre-set through hole 330 on the lower guard plate 300 to conveniently pass the mounting portion 520 through the upper surface of the first main body portion 310. The spoiler 500 can be conveniently installed without making major changes to the lower guard plate 300.

[0072] In some embodiments, Figure 5 , Figure 6 As shown, the connecting portion 320 at least has an inclined portion 321 extending backward and upward from the rear end of the first main body 310 to connect with the rear bumper 400, and a through hole 330 is provided on the inclined portion 321. The mounting portion 520 includes a first connecting portion 521, which extends to the top of the first main body 310 through the through hole 330, and the first connecting portion 521 is connected to the first main body 310. Therefore, by arranging the through hole 330 on the inclined portion 321, the through hole 330 can be avoided from the connecting position between the inclined portion 321 and the first main body 310, thereby avoiding affecting the structural strength of the connecting position between the inclined portion 321 and the first main body 310, and also avoiding the connecting position from interfering with the airflow at the bottom of the vehicle 10. At the same time, since the inclined portion 321 is inclined upward, that is, the inclined portion 321 is located above the first main body 310, by arranging the through hole 330 on the inclined portion 321, the through hole 330 can be located above the first main body 310. Therefore, by extending the first connection part 521 through the through hole 330 to above the first main body part 310, the first connection part 521 can be completely located above the first main body part 310 and the second main body part 510, thereby avoiding interference with the airflow flowing through the lower surfaces of the first main body part 310 and the second main body part 510, thereby avoiding increasing driving resistance.

[0073] In some embodiments, Figure 5 , Figure 6 As shown, the mounting portion 520 further includes a first connection hole 522, which is provided at the end of the first connection portion 521, and is used to achieve fixed connection with the first main body portion 310. The first connection portion 521 is bent, so that the lower surface of the second main body portion 510 is flush with the lower surface of the first main body portion 310. Thus, by providing the first connection hole 522 at the end of the first connection portion 521, it is convenient to fix the mounting portion 520 on the first main body portion 310 by means of bolts or rivets 528. By making the first connection portion 521 bent, it is convenient for the first connection portion 521 to pass through the through hole 330, and the first connection portion 310 can also avoid other structures on the lower guard plate 300, so as to facilitate the first connection hole 522 at the end of the first connection portion 521 to be fixedly connected with the first main body portion 310. By making the lower surface of the second main body 510 flush with the lower surface of the first main body 310 , the first main body 310 and the second main body 510 can be made smoother, thereby avoiding an increase in driving resistance when air flows through.

[0074] In some embodiments, the first connection portion 521 and the first main body portion 310 may be connected by welding, pasting, or snapping, etc., which is not limited thereto.

[0075] In some embodiments, Figure 5 As shown, a plurality of mounting portions 520 are arranged at intervals along the front end of the second main body 510. Thus, by arranging a plurality of mounting portions 520 at intervals along the front end of the second main body 510, the spoiler 500 can be fixedly connected to the lower guard plate 300 at multiple positions, thereby improving the firmness and stability between the spoiler 500 and the lower guard plate 300.

[0076] In some embodiments, Figure 5 As shown, a plurality of mounting portions 520 are evenly arranged along the front end of the second main body portion 510. Thus, the fixed connection between the spoiler 500 and the lower guard plate 300 can be made more uniform, thereby improving the firmness and stability between the spoiler 500 and the lower guard plate 300.

[0077] Figure 7 This is a schematic diagram of the three-dimensional structure after the spoiler 500 is installed on the lower guard plate 300 in Example 2; Figure 8 for Figure 7 A schematic diagram of a partial cross-sectional structure of the middle spoiler 500 at a position between two second connection holes 524; Fig. 9 for Figure 7 A schematic diagram of a partial cross-sectional structure of the middle spoiler 500 at the position of the second connection hole 524. Figure 7-Figure 9As shown, the mounting portion 520 is fitted with the lower surface of the first main body 310. Thus, by fitting the mounting portion 520 with the lower surface of the first main body 310 and achieving a fixed connection, the spoiler 500 can be installed directly under the vehicle 10. Thus, the difficulty of installing the spoiler 500 can be reduced, and the workload of the staff can be reduced. Moreover, by fitting the mounting portion 520 with the lower surface of the first main body 310, the degree of protrusion of the mounting portion 520 from the lower surface of the first main body 310 can be reduced, thereby reducing the impact on the airflow flowing under the first main body 310, thereby reducing the driving resistance.

[0078] In some embodiments, Figure 8 , Fig. 9 As shown, a groove 313 is provided on the lower surface of the first main body 310. The mounting portion 520 includes a second connecting portion 523 and a second connecting hole 524. The second connecting portion 523 is provided along the front end of the second main body 510, and at least a portion of the second connecting portion 523 is accommodated in the groove 313. Thus, by accommodating at least a portion of the second connecting portion 523 in the groove 313, the degree to which the mounting portion 520 and the second connecting portion 523 protrude from the lower surface of the first main body 310 can be reduced, thereby reducing the impact on the airflow flowing through the lower surface of the first main body 310, and reducing the driving resistance of the vehicle 10.

[0079] After the second connection portion 523 is partially accommodated in the groove 313 and connected to the first main body portion 310 at the groove, the height of the lower surface of the second connection portion 523 is not less than the height of the lower surface of the first main body portion 310. Therefore, when the airflow at the bottom of the vehicle 10 passes through the first main body portion 310 and then flows through the lower surface of the second connection portion 523, the driving resistance will not be significantly increased, thereby ensuring the smoothness of the airflow.

[0080] In some embodiments, Figure 8 , Fig. 9 As shown, the groove 313 is disposed near the position where the first main body 310 is connected to the inclined portion 321, and extends along the rear end of the first main body 310. Thus, the distance between the groove 313 and the second main body 510 on the spoiler 500 can be reduced, so that the installation position of the spoiler 500 is as close to the rear of the vehicle 10 as possible, and when the mounting portion 520 adapted to the groove 313 is disposed on the second main body 510, the size of the mounting portion 520 extending from the second main body 510 can be reduced, thereby making the structure of the spoiler 500 more compact.

[0081] In some embodiments, Figure 8As shown, the upper surface of the second connection portion 523 is provided with a reinforcing rib 525, and the reinforcing rib 525 is accommodated in the groove 313. Therefore, by providing the reinforcing rib 525 on the second connection portion 523, the structural strength of the second connection portion 523 can be improved. By accommodating the reinforcing rib 525 in the groove 313, the connection stability between the spoiler 500 and the first main body 310 can be enhanced, and when the bottom of the vehicle 10 is impacted by strong airflow or water, etc., it can prevent the front and rear directions from moving, thereby avoiding increasing the driving resistance.

[0082] In some embodiments, Figure 8 As shown, the height of the reinforcing rib 525 is set such that after the reinforcing rib 525 abuts against the groove 313, the lower surface of the second main body 510 is flush with the lower surface of the first main body 310. Thus, by setting the height of the reinforcing rib 525 such that after the reinforcing rib 525 abuts against the groove 313, the lower surface of the second main body 510 is flush with the lower surface of the first main body 310, so that the first main body 310 and the second main body 510 can be smoother, avoiding an increase in driving resistance when airflow passes through.

[0083] Fig.10 This is a schematic diagram of the three-dimensional structure after the spoiler 500 is installed on the lower guard plate 300 in Example 3; Fig.11 for Fig.10 A schematic diagram of a partial cross-sectional structure of the middle spoiler 500 at a position between two third connecting holes 527; Fig.12 for Fig.10 A schematic diagram of a partial cross-sectional structure of the middle spoiler 500 at the position of the third connecting hole 527. Figure 10-12 As shown, the spoiler 500 includes a second main body 510 and a mounting portion 520, the second main body 510 extends backward from the rear end of the first main body 310, and the mounting portion 520 is fixedly connected to the inclined portion 321. Since the inclined portion 321 is inclined upward, the inclined portion 321 is located above the first main body 310. In the present application, the mounting portion 520 is fixedly connected to the inclined portion 321, so that the mounting portion 520 can be located above the first main body 310. In this way, the mounting portion 520 can be prevented from being exposed from the lower surface of the first main body 310 to affect the airflow, and the connection position can also be prevented from interfering with the airflow at the bottom of the vehicle 10, thereby avoiding increasing the driving resistance.

[0084] In addition, by fixing the mounting portion 520 to the inclined portion 321, the airflow below the first main body 310 will not be affected, so the restrictions on the fixing connection method of the mounting portion 520 and the inclined portion 321 can be reduced. Therefore, the mounting portion 520 and the inclined portion 321 can be fixedly connected using a simpler connection method, so that the structure can be simpler.

[0085] In some embodiments, Figure 10-12 As shown, the mounting portion 520 includes a third connection portion 526, which is inclined along the front end of the second main body portion 510, and the inclination angle is set so that the third connection portion 526 fits the outer surface of the inclined portion 321. Thus, by setting the inclination angle of the third connection portion 526 so that the third connection portion 526 fits the outer surface of the inclined portion 321, the stability of the connection between the third connection portion 526 and the inclined portion 321 can be improved. In addition, the gap between the third connection portion 526 and the inclined portion 321 can be reduced, thereby reducing the accumulation of dust and other debris between the third connection portion 526 and the inclined portion 321.

[0086] In some embodiments, the mounting portion 520 further includes a third connection hole 527, which is disposed on the third connection portion 526 and fixedly connected to the inclined portion 321. Thus, by disposing the third connection hole 527 on the third connection portion 526, the mounting portion can be conveniently fixed to the inclined portion by means of bolts or rivets 528.

[0087] In some embodiments, the mounting portion 520 includes a fourth connection portion (not shown) and a fourth connection hole (not shown), the fourth connection portion is arranged at the front end position of the second main body portion 510, and the fourth connection portion is penetrated on the inclined portion 321. The fourth connection hole is arranged on the fourth connection portion and fixedly connected to the inner surface of the inclined portion 321. Among them, the fourth connection portion is arranged obliquely, and the inclination angle is set so that after the fourth connection hole is fixedly connected to the inner surface of the inclined portion 321, the lower surface of the second main body portion 510 is flush with the lower surface of the first main body portion 310. Thus, the mounting portion 520 can be fixedly connected to the inner surface of the inclined portion 321, so that the mounting portion 520 can be hidden above the lower guard plate 300. Thus, when the mounting portion 520 is fixed to the inclined portion 321 using fasteners such as rivets 528 or bolts, the fasteners can be prevented from protruding from the lower surface of the inclined portion 321, thereby improving the integrity of the lower surface of the lower guard plate 300. In addition, by hiding the mounting portion 520 above the lower guard plate 300 , it is also possible to prevent water accumulation, dirt, etc. from accumulating at the connection position between the mounting portion 520 and the inclined portion 321 , thereby affecting the stability of the connection between the spoiler 500 and the lower guard plate 300 .

[0088] In some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 7As shown, at least one maintenance port 311 is provided on the first main body 310, and / or a detachably connected cover 312 is provided on the maintenance port 311. Thus, by providing the maintenance port 311 on the first main body 310, it is convenient to repair the components above the lower guard plate 300 through the maintenance port 311. By providing the detachably connected cover 312 on the maintenance port 311, when it is necessary to repair the components above the lower guard plate 300, the maintenance port 311 can be exposed by opening and removing the cover 312, so as to facilitate the repair of the components above the lower guard plate 300 without disassembling the entire lower guard plate 300, thereby improving the maintenance efficiency and reducing the maintenance cost. Under normal circumstances, by installing the cover 312 on the maintenance port 311, the maintenance port 311 is closed, so that the airflow can be prevented from entering the upper part of the lower guard plate 300 from the maintenance port 311 to avoid increasing the driving resistance. At the same time, by closing the maintenance opening 311 through the cover 312, the components above the lower guard plate 300 can also be protected to prevent debris from entering the upper part of the lower guard plate 300 through the maintenance opening 311 and causing damage to the components above the lower guard plate 300.

[0089] In some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 7 As shown, the maintenance opening 311 is set at the position where the components above the lower guard plate 300 need to be disassembled for inspection and maintenance. The above content, combined with the drawings, exemplarily describes the possible embodiments of the vehicle rear structure. Below, combined with the drawings, combined with multiple specific embodiments, the specific structure of the vehicle rear structure in this application is described in detail.

[0090] Example 1

[0091] like Figure 1As shown, the vehicle 10 in the present application includes a vehicle body 100, a battery pack 200, a lower guard plate 300, a rear bumper 400 and a spoiler 500. Among them, the battery pack 200 is installed at the middle position of the bottom of the vehicle body 100 in the front-to-back direction, and is used to provide electrical energy for the vehicle 10. The lower guard plate 300 is installed at the bottom of the vehicle body 100, located at the rear position of the vehicle 10. The rear bumper 400 is installed at the rear of the vehicle body 100, extending from the rear side of the vehicle body 100 to the positions on both sides of the vehicle body 100 along the width direction of the vehicle 10 to protect the rear of the vehicle 10. The front end of the lower guard plate 300 is connected to the rear end of the battery pack 200, and the rear end of the lower guard plate 300 is connected to the lower edge of the rear bumper 400. The lower guard plate 300 extends basically horizontally, so that the bottom of the vehicle 10 is smoother, so that the airflow flows more smoothly through the bottom of the vehicle 10 to reduce driving resistance. The spoiler 500 is installed on the lower guard plate 300, and forms a vehicle rear structure together with the lower guard plate 300 and the rear bumper 400, etc., for guiding the airflow at the bottom of the vehicle 10 backwards, so that the vortex generated by the airflow is away from the rear of the vehicle 10, thereby reducing driving resistance.

[0092] like Figure 1-Figure 4 As shown, the lower guard plate 300 is a plate-shaped component, including an integrally formed first main body portion 310 and a connecting portion 320. The first main body portion 310 is located at the bottom of the vehicle 10 and is approximately horizontal. The front end of the first main body portion 310 is connected to the rear end of the battery pack 200, and the connecting portion 320 has an inclined portion 321 extending backward and upward from the rear end of the first main body portion 310 to connect to the rear bumper 400.

[0093] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the spoiler 500 includes an integrally formed second main body portion 510 and a mounting portion 520. The second main body portion 510 is plate-shaped and extends along the width direction of the vehicle 10. The mounting portion 520 is fixedly disposed on the second main body portion 510 and extends forward from the front edge of the second main body portion 510. The mounting portion 520 is used to be fixedly connected to the lower guard plate 300, so that the front end of the second main body portion 510 is connected to the rear end of the first main body portion 310, and the rear end of the second main body portion 510 extends backward from the first main body portion 310, so that the second main body portion 510 can guide the airflow backward. As shown in FIG. Figure 5 As shown, a plurality of mounting portions 520 are evenly spaced apart on the second main body portion 510 along the width direction of the vehicle 10 , and after the mounting portions 520 are fixedly connected to the lower guard plate 300 , the spoiler 500 can be made more stable and firm.

[0094] like Figure 4 , Figure 6As shown, the lower guard plate 300 is provided with a plurality of rectangular through holes 330, and the through holes 330 correspond to the mounting portions 520 of the lower guard plate 300 one by one. The mounting portions 520 can be as shown in FIG. Figure 6 As shown in the figure, the through hole 330 extends into the upper position of the lower guard plate 300 and is fixedly connected to the lower guard plate 300. Therefore, after installation, the mounting portion 520 can be placed above the lower guard plate 300 to avoid interference with the airflow below the vehicle 10, thereby reducing the impact on the car and reducing driving resistance. At the same time, the mounting portion 520 can be hidden above the lower guard plate 300 to avoid accumulation of water, dirt, etc. at the connection position between the mounting portion 520 and the lower guard plate 300, thereby affecting the stability of the connection between the spoiler 500 and the lower guard plate 300.

[0095] like Figure 5 , Figure 6 As shown, the mounting portion 520 includes a first connecting portion 521 and a first connecting hole 522. The first connecting portion 521 extends forward from the front edge of the second main body 510, and the first connecting hole 522 is arranged at the end of the first connecting portion 521, which can be fixed by bolts or other methods. Figure 6 The fastening components such as the rivets 528 shown in the figure pass through the first connecting portion 521 and are fixedly connected to the mounting holes at corresponding positions on the lower guard plate 300.

[0096] like Figure 4 , Figure 6 As shown, the through hole 330 is arranged on the inclined portion 321, and is located near the position where the inclined portion 321 is connected to the first main body portion 310. Thus, the through hole 330 can avoid the connection position between the inclined portion 321 and the first main body portion 310, so as to avoid affecting the structural strength of the connection position between the inclined portion 321 and the first main body portion 310. At the same time, Figure 6 As shown, the first connection portion 521 of the mounting portion 520 is bent upward in a "X" shape at the corresponding position of the through hole 330. Therefore, when the through hole 330 is higher than the first main body 310, the first connection portion 521 can be used to avoid it, so that the first connection portion 521 extends to the upper position of the first main body 310. After the first connection portion 521 is fixedly connected to the first main body 310, the lower surface of the second main body 510 can be kept flush with the lower surface of the first main body 310.

[0097] like Figure 1 , Figure 2 , Figure 4As shown, a plurality of maintenance ports 311 are provided on the first main body 310, and the maintenance ports 311 are provided at the position where the components above the lower guard plate 300 need to be disassembled when they are inspected and maintained, so as to facilitate the maintenance of the components above the lower guard plate 300 through the maintenance ports 311. A detachably connected cover 312 is also provided on the maintenance port 311, so that when the components above the lower guard plate 300 need to be repaired, the maintenance port 311 can be exposed by opening and removing the cover 312, so as to facilitate the maintenance of the components above the lower guard plate 300. Under normal circumstances, the maintenance port 311 is closed by installing the cover 312 on the maintenance port 311, so as to prevent the airflow from entering the upper part of the lower guard plate 300 through the maintenance port 311, so as to avoid increasing the driving resistance. At the same time, by closing the maintenance port 311 through the cover 312, the components above the lower guard plate 300 can also be protected, so as to prevent debris from entering the upper part of the lower guard plate 300 through the maintenance port 311 and causing damage to the components above the lower guard plate 300.

[0098] Example 2

[0099] The present application also provides a second lower guard plate 300 and a spoiler 500. The specific structures of the lower guard plate 300 and the spoiler 500 in Example 2 are described in detail below in conjunction with the accompanying drawings. For the parts not mentioned in Example 2, reference can be made to the relevant contents in Example 1, which will not be repeated here.

[0100] like Figure 7-Figure 9 As shown, the lower surface of the first main body 310 of the lower guard plate 300 is provided with a groove 313 near the position where the first main body 310 is connected to the inclined portion 321. The groove 313 extends along the position where the first main body 310 is connected to the inclined portion 321, and is adapted to the shape of the mounting portion 520. The mounting portion 520 of the spoiler 500 includes a second connecting portion 523 and a second connecting hole 524. The second connecting portion 523 is arranged along the front end of the second main body 510, and the second connecting hole 524 is arranged on the second connecting portion 523. The second connecting portion 523 can be fixedly connected to the mounting hole in the groove 313 by a rivet 528, so that the second connecting portion 523 extends into the groove 313, and the front side edge of the second connecting portion 523 is connected to the front side wall of the groove 313 (i.e., the side wall located on the front side of the two side walls in the groove 313). Thus, the mounting portion 520 can be hidden by the groove 313 , so that the mounting portion 520 is prevented from being exposed from the lower surface of the first main body portion 310 to affect the airflow and increase the driving resistance.

[0101] like Figure 8As shown, the upper surface of the second connection part 523 is provided with a reinforcing rib 525, and the reinforcing rib 525 extends along the second connection part 523 and is located between two adjacent second connection holes 524. Therefore, by providing the reinforcing rib 525 on the second connection part 523, the structural strength of the second connection part 523 can be improved. By providing the reinforcing rib 525 on the upper surface of the second connection part 523, the reinforcing rib 525 can be located on the side facing the first main body part 310, and after the second connection part 523 extends into the groove 313, the reinforcing rib 525 is located in the groove 313. In this way, the connection stability between the spoiler 500 and the first main body part 310 can be enhanced, and when the bottom of the vehicle 10 is impacted by strong airflow or water, etc., it can prevent the spoiler 500 from moving in the front and rear directions, thereby avoiding increasing the driving resistance.

[0102] In addition, if Figure 8 As shown, the height of the reinforcing rib 525 is set so that after the reinforcing rib 525 abuts against the bottom of the groove 313, the lower surface of the second main body 510 is flush with the lower surface of the first main body 310, thereby making the first main body 310 and the second main body 510 smoother and avoiding increased driving resistance when airflow passes through.

[0103] Example 3

[0104] The present application also provides a third lower guard plate 300 and a spoiler 500. The specific structures of the lower guard plate 300 and the spoiler 500 in Embodiment 3 are described in detail below in conjunction with the accompanying drawings. For the parts not mentioned in Embodiment 3, reference can be made to the relevant contents in Embodiment 1, which will not be repeated here.

[0105] like Figure 10-12 As shown, the mounting portion 520 is fixedly connected to the inclined portion 321. Figure 10-12 As shown in the figure, the mounting portion 520 is fixed on the lower surface of the inclined portion 321, so as to more conveniently fix the mounting portion 520 to the inclined portion 321. The mounting portion 520 may also be passed through the inclined portion 321, so that the mounting portion 520 is fixedly connected to the upper surface of the inclined portion 321, so that the mounting portion 520 can be hidden above the lower guard plate 300, and water and dirt are prevented from accumulating at the connection position between the mounting portion 520 and the inclined portion 321, thereby affecting the stability of the connection between the spoiler 500 and the lower guard plate 300. There is no limitation to this.

[0106] like Figure 10-12As shown, the mounting portion 520 includes a third connecting portion 526 and a third connecting hole 527. The third connecting portion 526 is arranged along the front end of the second main body 510, and the third connecting hole 527 is arranged on the third connecting portion 526. Specifically, a plurality of protrusions are evenly spaced at the front end of the third connecting portion 526, and a plurality of third connecting holes 527 are correspondingly arranged on the protrusions, which are fixedly connected with the inclined portion 321, so that the front end of the second main body 510 is connected with the rear end of the first main body 310. There are a plurality of third connecting holes 527, which are evenly arranged along the third connecting portion 526, and can be fixedly connected with the mounting holes at the corresponding positions of the inclined portion 321 by rivets 528, so that the connection between the spoiler 500 and the lower guard plate 300 is more stable and firm.

[0107] like Figure 10-12 As shown, after the third connection hole 527 is fixedly connected to the inclined portion 321, the third connection portion 526 is in contact with the lower surface of the inclined portion 321, thereby further improving the stability of the connection between the spoiler 500 and the lower guard plate 300. At the same time, the third connection portion 526 is tilted on the second main body 510, and the tilt angle is set so that after the third connection portion 526 is in contact with the lower surface of the inclined portion 321, the lower surface of the second main body 510 is flush with the lower surface of the first main body 310. In this way, the first main body 310 and the second main body 510 can be made smoother, avoiding the increase of driving resistance when the airflow passes through.

[0108] Note that the above are only preferred embodiments of the present application and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present application is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, all of which belong to the scope of protection of the present invention.
