Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the front part of the vehicle body, especially relates to a vehicle body structure, and simultaneously, the utility model also relates to a vehicle provided with the vehicle body structure. BACKGROUND

[0002] The automobile front fender is a key part of the outer plate of the vehicle body, not only bears the important function of protecting the wheel and the suspension system, but also plays an important role in the whole vehicle modeling design and aerodynamic performance optimization. With the progress of automobile industry technology, the design of the front fender has gradually evolved from a simple structural part to a composite part with functionality and aesthetics. However, the existence of the front fender also makes it difficult to discharge the turbulent flow in the wheel arch in time, resulting in larger wind noise, larger wind resistance coefficient, smaller endurance mileage, and poor heat dissipation performance of the front wheel brake system, which is difficult to alleviate the brake heat attenuation phenomenon under intense driving conditions. SUMMARY

[0003] Therefore, the utility model aims at providing a vehicle body structure to reduce the turbulent flow around the vehicle, reduce the wind resistance coefficient, and reduce energy consumption.

[0004] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0005] A vehicle body structure, comprising a front fender, a ventilation opening provided on the front fender, a blocking plate provided at the ventilation opening, and a driving part connected with the blocking plate;

[0006] The ventilation opening is provided at the rear end of the front fender and extends in the front-rear direction of the whole vehicle, the blocking plate is adapted to the ventilation opening, and the driving part can drive the blocking plate to move to adjust the plugging state of the blocking plate to the ventilation opening.

[0007] Further, the front fender comprises a fender body and a ventilation part provided at the rear end of the fender body;

[0008] The ventilation opening is provided on the ventilation part and extends in the up-down direction of the whole vehicle.

[0009] Further, the rear end of the fender body is provided with a groove recessed to the inside of the vehicle;

[0010] The ventilation part is embedded in the groove and provided with an opening corresponding to the ventilation opening in the groove.

[0011] Further, the ventilation part comprises a first plate body and a second plate body provided at the rear end of the first plate body;

[0012] The front end of the second plate body is recessed towards the inside of the vehicle, and forms the air vent together with the first plate body.

[0013] Further, the first plate body and the second plate body are provided with a mounting plate, which is arched towards the outside of the vehicle.

[0014] The mounting plate is provided with a component mounting hole, which is arranged along the front-rear direction of the vehicle and located at the rear side of the air vent.

[0015] Further, the mounting plate is provided with a recessed portion, and the component mounting hole is arranged on the recessed portion.

[0016] Further, the blocking plate is provided with an elastic portion between the blocking plate and the front fender.

[0017] Under the elastic action of the elastic portion, the blocking plate keeps blocking the air vent.

[0018] Further, the front fender is provided with a fender reinforcing plate, which is arranged along the up-down direction of the vehicle and extends towards the inside of the vehicle.

[0019] The blocking plate is rotatably arranged on the fender reinforcing plate.

[0020] Further, the driving portion comprises a motor arranged on the fender reinforcing plate, and the motor is connected with the rotating shaft of the blocking plate in transmission.

[0021] Compared with the prior art, the vehicle body structure has the following advantages:

[0022] The vehicle body structure sets the air vent at the rear end of the front fender, sets the blocking plate for blocking the air vent, and sets the driving portion for adjusting the blocking state, so that the driving portion controls the movement of the blocking plate according to the needs during the driving of the vehicle. When the vehicle is driven at high speed, the blocking plate is appropriately opened to open the air vent, so that the airflow can be guided to pass through, the turbulent flow around the vehicle is reduced, the wind resistance coefficient is reduced, and then the energy consumption is reduced, the fuel economy is improved, or the cruising range of the electric vehicle is increased. Under the daily road conditions, the air vent can be completely blocked, the sewage, sand and other sundries splashed by the wheels can be effectively blocked from entering the air vent, the paint surface of the vehicle body at the rear of the front fender can be effectively protected, the flying sand and stones can be prevented from damaging the paint surface of the vehicle body, the product maintenance economy can be improved, and the maintenance cost can be reduced.

[0023] In addition, the air vent is arranged at the rear end of the wing panel, which can better conform to the air flow direction, so that the air flow in and out of the air vent is better integrated with the main air flow around the vehicle body, reducing the turbulence caused by air flow conflict. Compared with arranging the air vent at the front end of the front wing panel, the probability of foreign matter directly impacting the air vent can be effectively reduced, and the pressure of the blocking plate and the air vent inside being invaded by foreign matter can be greatly reduced. Moreover, by arranging the blocking plate to fit the air vent, the blocking plate can be tightly fitted in the closed state to prevent air flow, dust, rainwater or road debris from entering the wheel arch area through the gap. In addition, the air vent can avoid the feeling of being conspicuous and improve the appearance and design of the vehicle.

[0024] Secondly, the air vent is arranged on the ventilation member in the up-down direction of the vehicle, which can facilitate the air flow management of the vehicle in the vertical direction. When the vehicle is driving on a road with significant air flow changes in the up-down direction, the blocking plate is controlled to move by the driving part to open the air vent, so that the air flow can flow more smoothly in the vertical direction, balance the air pressure difference near the wing panel caused by the terrain, and reduce the influence of air flow turbulence on the vehicle handling stability. At the same time, when the air vent needs to be repaired or replaced, only the ventilation member needs to be replaced, which can reduce the maintenance cost.

[0025] By arranging a recess recessed to the inside of the vehicle at the rear end of the wing panel body, and embedding the ventilation member in the recess, a protected installation space can be provided for the ventilation member. In the event of a minor collision or scratching accident, the recess can buffer the direct impact of external impact force on the ventilation member, reducing the risk of damage to the ventilation member, ensuring the integrity of the ventilation system, reducing maintenance cost and frequency, and ensuring normal operation of the vehicle. Moreover, in the production and manufacturing process, the recess serves as a specific installation position for the ventilation member, providing precise positioning for the assembly process. Workers can quickly and accurately install the ventilation member according to the recess structure, improving production efficiency.

[0026] Furthermore, the ventilation member is formed by the first plate body and the second plate body recessed at the rear end to form the air vent. During vehicle driving, air flow flows along the vehicle body to this place, and the air vent can better guide the air flow. The air flow can be more efficiently gathered into the air vent and then flow to the front wheel area that needs to be cooled, improving the cooling efficiency and enhancing the synergistic effect of aerodynamics and vehicle functionality. In addition, compared with the planar air vent, the light and shadow on the first plate body and the recessed second plate body will produce different refraction effects, and the air vent area will present a unique light and shade contrast, making the vehicle side more visually recognizable, meeting the needs of consumers pursuing personalized and differentiated automobile appearance design, and improving the competitiveness of the product in the market.

[0027] Further, the installation plate is arranged between the first plate body and the second plate body and arches outwardly, so that a three-dimensional space of the ventilation member is utilized to provide an installation area for components that need to be additionally assembled, so as to avoid spatial interference with the ventilation opening and other internal components. Moreover, the installation plate can serve as a support structure to withstand installation stress from the components and partial external impact during vehicle operation. The arching shape of the installation plate outwardly is similar to a small reinforcing rib, which can effectively enhance the local structural strength of the ventilation member and the entire fender. When the vehicle is subjected to slight shaking, jolting or side extrusion, the installation plate can disperse the force transmission and maintain the stability of the ventilation member structure, so as to ensure that the ventilation function is not affected, reduce the risk of vehicle failure caused by structural deformation, and improve the overall reliability of the vehicle.

[0028] By arranging a recessed portion on the installation plate and arranging the component mounting hole in the recessed portion, the recessed portion provides a positioning groove for the installation of the component, which is beneficial to ensure the stability and accuracy of the component installation. Moreover, the recessed portion can block most of the direct force from the outside, so as to avoid damage to the component mounting hole and the connected component.

[0029] By arranging an elastic portion between the blocking plate and the front fender, the blocking plate is always subjected to a stable force towards the ventilation opening, so as to effectively prevent the blocking plate from loosening and the gap from increasing due to vehicle shaking, and to maintain the good plugging state of the ventilation opening. In this way, on the one hand, this helps to optimize the aerodynamic performance of the vehicle, reduce wind resistance, and thus reduce fuel consumption or improve the cruising range of electric vehicles. On the other hand, it can effectively suppress the additional noise generated by the turbulent flow through the gap, improve the quietness of the in-vehicle driving environment, and provide passengers with a more comfortable travel experience.

[0030] In addition, by additionally arranging a fender reinforcing plate on the front fender, the fender reinforcing plate is arranged in the up-down direction of the vehicle and extends inwardly, so as to effectively disperse the force and prevent the front fender from being excessively deformed due to external force, so as to ensure that the ventilation structure is always in the correct working position and the stability of the aerodynamic performance of the vehicle is ensured. By rotating the blocking plate on the fender reinforcing plate, the rotation shaft of the blocking plate can obtain more reliable installation stability by means of the stable structure of the reinforcing plate. In this way, the movement track of the blocking plate during opening or closing is smoother, and unstable phenomena such as jamming and shaking are reduced.

[0031] By directly arranging the motor on the fender reinforcing plate and connecting the rotation shaft of the blocking plate in transmission, this close connection greatly reduces the loss and delay of power during transmission, so that the motor can accurately and quickly transmit torque to the rotation shaft of the blocking plate. In addition, the motor is installed on the fender reinforcing plate, which can fully utilize the stable structure characteristics of the reinforcing plate, not only providing a reliable installation basis for the motor, but also making the layout of the entire ventilation opening driving system more compact.

[0032] Another purpose of the utility model lies in providing a vehicle, the vehicle is equipped with the vehicle body structure as described above.

[0033] The vehicle, through the vehicle body structure as described above, when the vehicle is in normal driving, the air vent can be completely blocked.

[0034] When the vehicle is running at high speed, the driving part can control the blocking plate to open the air vent, guide the airflow to pass through, effectively reduce the turbulence in the wheel arch, reduce the whole vehicle wind resistance coefficient, thereby improving the fuel economy or the cruising range of the vehicle.

For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood in combination with the specific circumstances.

[0052] The utility model will be explained in detail below with reference to the drawings and in combination with the embodiments.

[0053] Embodiment one

[0054] The front fender is located above the front wheel of the automobile, and mainly functions to shield the mud, stones and other sundries splashed by the wheel during driving, so as to prevent them from splashing to other parts of the vehicle body, and to protect the paint surface and chassis components from mud erosion and stone impact. Meanwhile, the front fender can play a certain buffering role when the vehicle is slightly collided, so as to absorb and disperse the collision energy, reduce the damage to other important components of the vehicle body, and reduce the maintenance cost. However, the existence of the front fender also makes the turbulent flow in the wheel arch difficult to be discharged in time, which is easy to cause obvious wind noise problem, and leads to a larger wind resistance coefficient, smaller cruising range, and poor heat dissipation performance of the front wheel braking system, which is difficult to alleviate the brake heat decay phenomenon under intense driving conditions.

[0055] Therefore, the embodiment particularly provides a vehicle body structure, which comprises a front fender 1, a ventilation opening K arranged on the front fender 1, a blocking plate 2 arranged at the ventilation opening K, and a driving part connected with the blocking plate 2. The ventilation opening K is arranged at the rear end of the front fender 1 and extends along the front-rear direction of the whole vehicle, the blocking plate 2 is adapted to the ventilation opening K, and the driving part can drive the blocking plate 2 to move, so as to adjust the blocking state of the blocking plate 2 to the ventilation opening K.

[0056] The vehicle body structure of the embodiment can control the movement of the blocking plate 2 by the driving part when the airflow needs to be adjusted during the driving of the vehicle. When the vehicle is driven at high speed, the blocking plate 2 is appropriately opened to open the ventilation opening K, so that the airflow can be guided to pass through, the turbulent flow around the vehicle is reduced, the wind resistance coefficient is reduced, and then the energy consumption is reduced, the fuel economy is improved, or the cruising range of the electric vehicle is increased.

[0057] In daily driving, the ventilation opening K can be completely blocked, which can play a good protection effect on the paint surface at the rear part of the fender, can block the flying sand and stones from attacking the paint surface of the vehicle body in all directions, and greatly reduces the risk of damage to the paint surface. At the same time, the sewage, sand and other sundries splashed by the wheel can also be effectively blocked from entering the ventilation opening K, so as to avoid the erosion and damage of these foreign matters to the front wheel suspension system, braking components and the like, prolong the service life of the components, and reduce the vehicle failure rate.

[0058] Based on the above overall introduction, one exemplary structure of the vehicle body structure of the embodiment is described with reference to Figure 1 and Figure 2As shown in the figure, and for the purpose of clearly showing the improvement of the present embodiment, only the partial structure of the vehicle body structure is shown, and based on the general structure of the vehicle body being approximately left-right symmetrical, the present embodiment will only take the front fender 1 located on the left side of the vehicle body as an example for description. Among them, the same as the prior art, the front fender 1 is installed above the front wheel of the vehicle, surrounds the front wheel of the vehicle, is connected with the front longitudinal beam and the front firewall, and is the outer panel of the vehicle body covering the wheel. And the front fender 1 is located between the two side edges of the engine cover and the front wheel, and the rear part is connected with the door to ensure the smoothness of the vehicle body line.

[0059] And the air vent K is arranged at the rear end of the fender, which can conform to the airflow direction, so that the airflow entering and exiting the air vent K is better integrated with the main airflow around the vehicle body, reducing the turbulence caused by airflow conflict. Especially at high speed, the rear air vent K can better guide the turbulence in the front wheel arch out of the vehicle by the force of the vehicle moving forward, which can further optimize the aerodynamic performance of the whole vehicle and reduce the wind resistance. In addition, in daily driving, the area in front of the wheel is more likely to directly contact various foreign matters splashed by the road surface. By placing the air vent K at the rear, the probability of foreign matters directly impacting the air vent K can be reduced. When the vehicle drives at high speed on a road with debris, most of the debris splashed by the front wheel will be blocked by the vehicle body structure or scattered forward due to inertia, and only a small amount of debris may reach the rear end of the fender, greatly reducing the pressure on the blocking plate 2 and the air vent K inside from being invaded by foreign matters, better protecting the normal operation of the ventilation system, and further damaging the paint surface of the door.

[0060] In addition, as a preferred embodiment, as shown in Figure 1 The front fender 1 of the present embodiment includes a fender body 101 and a ventilation member 102 arranged at the rear end of the fender body 101. And the air vent K is arranged on the ventilation member 102 and extends in the vertical direction of the vehicle. Here, by arranging the air vent K on the ventilation member 102 in the vertical direction of the vehicle, when the vehicle drives on a mountain road with large ups and downs or an abrupt slope when entering or leaving an underground parking lot, the airflow in the vertical direction changes significantly. At this time, by controlling the movement of the blocking plate 2 through the driving part to open the air vent K, the airflow can flow more smoothly in the vertical direction, balance the air pressure difference near the fender caused by the terrain ups and downs, and reduce the impact of airflow turbulence on the vehicle handling stability.

[0061] In addition, the ventilation opening K is arranged on the ventilation member 102. When the ventilation opening K is worn or damaged and needs to be repaired or replaced, only the ventilation member 102 needs to be replaced. Unlike the conventional complex structure, the entire front wing panel 1 does not need to be disassembled, which can reduce the maintenance cost and efficiency. In addition, as a preferred embodiment, the ventilation opening K is substantially in the shape of a "C" in the left-right direction of the vehicle. In this way, the ventilation opening K can guide the airflow more efficiently and can more finely comb the airflow in the left-right direction, reduce the resistance caused by the turbulent airflow, and optimize the wind resistance coefficient of the vehicle. On the other hand, the "C"-shaped ventilation opening K can also add a sense of dynamic and technology to the vehicle body.

[0062] It should be noted that, in addition to the C-shaped ventilation opening K, it can also be rectangular, oval or other shapes.

[0063] Here, as a preferred embodiment, as shown in Figure 4 , the rear end of the wing panel body 101 is provided with a recess 1011 recessed toward the inside of the vehicle. The ventilation member 102 is embedded in the recess 1011 and is provided with an opening 10111 corresponding to the ventilation opening K in the recess 1011. By providing the recess 1011 recessed toward the inside of the vehicle at the rear end of the wing panel body 101, a protected installation space is provided for the ventilation member 102. In the event of a minor collision of the vehicle, the recess 1011 can buffer the direct effect of external impact force on the ventilation member 102, reduce the risk of damage to the ventilation member 102, ensure the integrity of the ventilation system, reduce maintenance costs and frequency, and ensure normal operation of the vehicle. Moreover, in the production and manufacturing process, the recess 1011 can provide a specific mounting position for the ventilation member 102, and workers can quickly and accurately install the ventilation member 102 according to the structure of the recess 1011, which can improve production efficiency.

[0064] As shown in Figure 5 , as a preferred embodiment, the ventilation member 102 includes a first plate body 1021 and a second plate body 1022 arranged at the rear end of the first plate body 1021, and the front end of the second plate body 1022 is recessed toward the inside of the vehicle and forms the ventilation opening K with the first plate body 1021. In this embodiment, the ventilation member 102 is formed by the first plate body 1021 and the second plate body 1022 recessed at the rear end, and the ventilation opening K can guide the airflow more finely according to Bernoulli's principle during vehicle driving, thereby improving the heat dissipation efficiency. In addition, in other embodiments, a filter screen can also be arranged at the ventilation opening K. At this time, the double-layer plate body formed by the first plate body 1021 and the second plate body 1022 can facilitate the arrangement of the filter screen.

[0065] In addition, from the perspective of appearance design, the vent K formed by the double-layer plate body structure of the first plate body 1021 and the second plate body 1022 adds rich levels and three-dimensionality to the front fender 1. Compared with the planar vent K, light and shadow will produce different refraction effects on the first plate body 1021 and the recessed second plate body 1022, especially under sunlight, the vent K area will present a unique light and shade contrast, making the vehicle side more visually recognizable, meeting the needs of consumers pursuing personalized and differentiated automobile appearance design, and improving the competitiveness of the product in the market.

[0066] Continuing to refer to Figure 5 As a further embodiment, in the present embodiment, a mounting plate 1023 is arranged between the first plate body 1021 and the second plate body 1022, and the mounting plate 1023 arches outward. In addition, the mounting plate 1023 is provided with a component mounting hole 10231, and the component mounting hole 10231 is arranged along the front-rear direction of the vehicle and located at the rear side of the vent K. In the present embodiment, by arranging the mounting plate 1023 arching outward between the first plate body 1021 and the second plate body 1022, the space inside the vent 102 can be fully utilized. This arching design provides a mounting area for components that need to be additionally assembled, which is beneficial to avoid spatial interference with the vent K and other internal components.

[0067] In addition, the mounting plate 1023 itself can serve as a support structure to withstand the installation stress from the components and part of the external impact during vehicle operation. Among them, the mounting plate 1023 arches outward, which is equivalent to a reinforcing rib, which can effectively enhance the local structural strength of the vent 102 and the entire fender. When the vehicle is subjected to slight vibration, jolt or side extrusion, the mounting plate 1023 can disperse the force transmission, maintain the stability of the structure of the vent 102, ensure the ventilation function, reduce the risk of vehicle failure caused by structural deformation, and improve the overall reliability of the vehicle. As a preferred embodiment, the mounting plate 1023 is integrally formed with the first plate body 1021 and the second plate body 1022.

[0068] As a further embodiment, as shown in Figure 5 As shown in the present embodiment, the mounting plate 1023 is provided with a recessed portion, and the component mounting hole 10231 is arranged on the recessed portion. The arrangement of the recessed portion can provide a positioning groove for the installation of components, which is beneficial to ensure the stability and accuracy of the component installation. Specifically, during implementation, the component mounting hole 10231 can be used to install a side turn signal lamp, a radar or a camera lamp component according to design requirements.

[0069] In addition, in order to obtain better use effect, the elastic part is arranged between the blocking plate 2 and the front wing panel 1. And under the elastic action of the elastic part, the blocking plate 2 keeps plugging the air vent K. In this way, the characteristics of the elastic part can be utilized to make the blocking plate 2 always receive a stable force towards the air vent K. Therefore, the elastic part can continuously press the blocking plate 2 to ensure that it closely fits the air vent K, effectively prevents the blocking plate 2 from loosening and the gap from increasing due to vehicle shaking, and always maintains a good plugging state of the air vent K, thereby protecting the internal components of the vehicle from external debris. On the one hand, this helps to optimize the aerodynamic performance of the vehicle, reduce wind resistance, and thus reduce fuel consumption or increase the cruising range of electric vehicles; on the other hand, it can effectively suppress the additional noise generated by the turbulent flow through the gap, and improve the quietness of the vehicle interior.

[0070] At this time, in order to facilitate the arrangement of the blocking plate 2, as a specific embodiment, as shown in Figure 3 , the front wing panel 1 is provided with a wing panel reinforcing plate 103, the wing panel reinforcing plate 103 is arranged in the up-down direction of the whole vehicle and extends to the inside of the vehicle, and the blocking plate 2 is rotatably arranged on the wing panel reinforcing plate 103. In this embodiment, by additionally arranging the wing panel reinforcing plate 103 which is arranged in the up-down direction of the whole vehicle and extends to the inside of the vehicle on the front wing panel 1, the stress can be effectively dispersed to prevent the front wing panel 1 from being excessively deformed due to external force, and the air vent structure can always be kept in the correct working position to ensure the stable play of the aerodynamic performance of the vehicle.

[0071] And the blocking plate 2 is rotatably arranged on the wing panel reinforcing plate 103, so that the rotating shaft of the blocking plate 2 can be more reliably installed based on the stable structure of the reinforcing plate. Therefore, the movement track of the blocking plate 2 during opening or closing is more smooth, and unstable phenomena such as jamming and shaking are reduced.

[0072] As a specific embodiment, as shown in Figure 3 and Figure 6 , the wing panel reinforcing plate 103 includes a reinforcing plate body 1031 extending to the inside of the vehicle, and a flange 1032 arranged at the end of the reinforcing plate body 1031 close to the outside of the vehicle. The wing panel reinforcing plate 103 is connected to the above-mentioned wing panel body 101 through the flange 1032. In addition, in order to further improve the structural reinforcing effect on the front wing panel 1, as shown in Figure 6 , a plurality of protruding parts are formed on the reinforcing plate body 1031 and arranged in the up-down direction.

[0073] The blocking plate 2 of the embodiment is arranged on the reinforcing plate body 1031 by rotating the rotating shaft 5. The elastic member is a torsion spring 4 sleeved on the rotating shaft 5, and the two ends of the torsion spring 4 are respectively in abutment with the blocking plate 2 and the reinforcing plate body 1031. In addition, in order to improve the stability of the blocking plate 2, the torsion spring 4 can be arranged in multiple on the rotating shaft 5 in specific implementation, for example, two torsion springs 4 arranged at the two ends of the rotating shaft 5 as shown in the schematic view. Figure 7 Thus, when the torsion spring 4 is in a natural state, the blocking plate 2 keeps blocking the air vent K, and when the driving part drives the rotating shaft 5 to rotate, the elastic force of the torsion spring 4 can be overcome to make the blocking plate 2 unblock the air vent K, so as to change the blocking state of the air vent K.

[0074] In specific implementation, the blocking plate 2 can be made of a lightweight alloy material with high strength, such as aluminum alloy. The aluminum alloy has the advantage of low density, which makes the blocking plate 2 not add too much extra weight to the vehicle as a whole after being installed on the front fender 1, helps to maintain the handling performance of the vehicle, and avoids affecting the flexibility and stability of driving due to local weight increase. At the same time, the aluminum alloy has excellent strength and can withstand a certain degree of external impact, effectively resist the impact of debris splashed by the wheels during daily driving, and slight scratches and collisions, prevent deformation and damage of itself, and protect the blocking effect of the air vent K.

[0075] In addition, as a further embodiment, a sealing gasket can be arranged on the side of the blocking plate 2 facing the air vent K, and the sealing gasket is arranged along the edge of the blocking plate 2, or a sealing gasket is arranged along the edge of the opening 10111 on the fender body 101. Thus, when the blocking plate 2 is rotated to the blocking position, the sealing strip is extruded and deformed elastically to fill the gap between the blocking plate 2 and the air vent K, which can effectively block the mud, stones and rainwater and other foreign matters splashed by the wheels from entering the air vent K, and prevent the paint surface of the door from being damaged by the debris.

[0076] In addition, as a preferred embodiment, the driving part of the embodiment includes a motor 3 arranged on the fender reinforcing plate 103, and the motor 3 is in transmission connection with the rotating shaft 5 of the blocking plate 2. The motor 3 is a driving part commonly used by those skilled in the art, which is mature in technology and easy to obtain. By installing the motor 3 on the fender reinforcing plate 103, the stable structural characteristics of the fender reinforcing plate 103 can be fully utilized, which not only provides a reliable mounting base for the motor 3, but also makes the layout of the entire air vent K driving system more compact.

[0077] As an optional embodiment, a dedicated motor mounting seat can be arranged on the fender reinforcement plate 103, and the mounting seat can be integrally cast or welded with the reinforcement plate to ensure sufficient strength to bear the weight of the motor 3 and the vibration and impact force generated during operation. Meanwhile, positioning holes and threaded holes are designed on the mounting seat, and the motor 3 can be accurately fixed in the predetermined position through the matched bolt and nut assembly, avoiding the interference of the motor 3 with other parts due to installation deviation.

[0078] As shown in FIG. 1, the motor 3 is arranged on the fender reinforcement plate 103, and the driving shaft of the motor 3 is directly connected with the rotating shaft 5 of the plug plate 2. Figure 7 As shown in FIG. 1, the motor 3 is arranged on the fender reinforcement plate 103, and the driving shaft of the motor 3 is directly connected with the rotating shaft 5 of the plug plate 2.

[0079] Therefore, even if the power of the motor 3 is limited, the gear assembly can provide strong and stable driving force for the rotating shaft 5 of the plug plate 2, ensuring that the plug plate 2 can accurately and smoothly complete the rotating motion under various working conditions. For example, when the vehicle needs to quickly open or close the air vent K to adjust the airflow during high-speed driving, the strong torque ensures the timeliness and reliability of the state switching of the air vent K. Therefore, the requirements for the motor 3 can be reduced, and the motor 3 can be arranged conveniently.

[0080] It should be noted that, in addition to connecting the motor 3 and the plug plate 2 through the gear assembly, connecting the driving shaft of the motor 3 and the rotating shaft 5 of the plug plate 2 directly is also theoretically feasible.

[0081] The vehicle body structure of the embodiment can not only open the air vent K to guide the airflow to pass through and effectively reduce the turbulent flow in the wheel arch and reduce the drag coefficient of the vehicle. Moreover, the air vent K can be completely blocked when the vehicle is driving normally. Therefore, the paint surface at the rear of the fender can be effectively protected, and the risk of damage to the paint surface can be greatly reduced.

[0082] Embodiment Two

[0083] Another purpose of the embodiment is to provide a vehicle provided with the vehicle body structure of embodiment one.

[0084] The vehicle of the embodiment can completely block the air vent K during normal driving by setting the vehicle body structure as in Embodiment One.

[0085] When the vehicle is driving at high speed, the driving part can control the blocking plate 2 to open the air vent K to guide the airflow to effectively reduce the turbulence in the wheel arch and reduce the wind resistance coefficient of the vehicle, thereby improving the fuel economy or the cruising range of the vehicle.
