Description

[0002] An intake grille is usually provided at the front of a vehicle or other vehicle. The intake grille is used to connect the inside and outside of the vehicle body, and fresh air from the outside can be sent into the vehicle body through the intake grille, so as to cool the corresponding devices and modules inside the vehicle body.

[0003] Currently, with the increasing diversification of the functions of vehicles, the demand for the heat dissipation area under specific working conditions will increase significantly. For example, for a flying car, a large amount of heat is generated when its land vehicle charges the flying vehicle, so a larger heat dissipation area is required. If the above heat dissipation requirements are to be met, a large number of intake grilles need to be provided at the front of the vehicle.

[0053] The realization, functional features and advantages of the purpose of the present application will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0054] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0055] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present application, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If this specific posture changes, then the directional indications will also change accordingly.

[0056] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present application, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0057] Currently, with the increasing diversification of the functions of transportation tools, the demand for the heat dissipation area under specific working conditions will increase significantly. For example, for a flying car, a large amount of heat will be generated when its land body charges the flying body, so a larger heat dissipation area is required. And if the above heat dissipation requirements are to be met, a large number of intake grilles need to be arranged at the front of the transportation tool. In this way, the overall appearance will be affected due to too many holes at the front, and the front part of the transportation tool will be greatly restricted in terms of styling design.

[0058] The R & D personnel of the present application have found through research that the above problems can be solved by setting up an active intake grille. Specifically, the active intake grille remains closed under normal working conditions and opens when the heat dissipation demand increases significantly. In this way, it can be avoided that a large number of holes are continuously exposed at the front of the transportation tool, which has an adverse impact on the appearance and styling design. However, the current active intake grilles all rotate towards the interior of the vehicle when opened, and there is a lack of support behind them; when the area and quantity of the active intake grilles are large, it will lead to a lack of stiffness, strength, and manufacturing feasibility at the front of the transportation tool.

[0059] To solve the above problems, the present application proposes an intake grille structure, aiming to combine the traditional fixed intake grille and the active intake grille, and reasonably arrange the two intake grilles at the front of the vehicle body, so as to meet the heat dissipation requirements under different working conditions, improve the visual quality of the front of the vehicle body and ensure the structural strength of the front of the vehicle body.

[0060] Please refer to Figures 1 to 6 , the intake grille structure proposed in an embodiment of the present application is applied to the vehicle body 100. The front of the vehicle body 100 is provided with a bottom intake port 110, a forward intake port 120 and a lateral intake port 130; the intake grille structure includes:

[0061] A normally open intake grille 1, which is arranged in the bottom intake port 110;

[0062] A forward active intake grille assembly 2, having forward blades 201, and the forward blades 201 cover the forward intake port 120; the forward active intake grille assembly 2 is used to drive the forward blades 201 to move towards the inner side of the vehicle body 100, so that at least part of the forward intake port 120 is opened;

[0063] A lateral active intake grille assembly 3, having lateral blades 301, and the lateral blades 301 cover the lateral intake port 130; the lateral active intake grille assembly 3 is used to drive the lateral blades 301 to move towards the outer side of the vehicle body 100, so that at least part of the lateral intake port 130 is opened.

[0064] In this embodiment, the vehicle body 100 may refer to the body part of a vehicle with a load-bearing function such as an automobile or a truck; when the vehicle is a flying car, the vehicle body 100 may specifically refer to the land-traveling part of the flying car. The bottom intake port 110, the forward intake port 120, and the lateral intake port 130 are used to connect the inside and outside of the vehicle body 100, and can cooperate with a suction device to send fresh external air into the vehicle body 100, so as to achieve the effect of dissipating heat and cooling the corresponding devices and modules inside the vehicle body 100. The bottom intake port 110 may be arranged at the lower side edge of the front of the vehicle body 100 to avoid the position of the normally open intake grille 1 being too conspicuous and damaging the styling design of the front of the vehicle body 100; the forward intake port 120 may be arranged above the bottom intake port 110 and face directly forward of the vehicle body 100. In this way, when the forward active intake grille assembly 2 is in the closed state, that is, when the forward blades 201 cover the forward intake port 120, the outer side of the forward blades 201 can form a part of the front side of the vehicle body 100; the lateral intake port 130 may be arranged above the bottom intake port 110 and face the side front of the vehicle body 100. In this way, when the lateral active intake grille assembly 3 is in the closed state, that is, when the lateral blades 301 cover the lateral intake port 130, the outer side of the lateral blades 301 can also form a part of the front side of the vehicle body 100.

[0065] The forward active intake grille assembly 2 includes a driving member and a corresponding transmission mechanism. When it is necessary to use the forward air inlet 120 for air exchange between the inside and outside of the vehicle body 100, the driving member can cooperate with the transmission mechanism to drive the forward vane 201 to move towards the inside of the vehicle body 100 along a preset path, so that the forward vane 201 deflects from the forward air inlet 120 and enters the inside of the vehicle body 100, so that the forward air inlet 120 is partially or fully opened. At this time, air circulation can be realized through the forward air inlet 120; when it is not necessary to use the forward air inlet 120 for air exchange between the inside and outside of the vehicle body 100, the driving member can cooperate with the transmission mechanism to drive the forward vane 201 to move in the reverse direction along a preset path, so that the forward vane 201 covers the forward air inlet 120 again. Similarly, the lateral active intake grille assembly 3 includes a driving member and a corresponding transmission mechanism. When it is necessary to use the lateral air inlet 130 for air exchange between the inside and outside of the vehicle body 100, the driving member can cooperate with the transmission mechanism to drive the lateral vane 301 to move towards the outside of the vehicle body 100 along a preset path, so that the lateral vane 301 deflects from the lateral air inlet 130 and moves to the outside of the vehicle body 100, so that the lateral air inlet 130 is partially or fully opened. At this time, air circulation can be realized through the lateral air inlet 130; when it is not necessary to use the lateral air inlet 130 for air exchange between the inside and outside of the vehicle body 100, the driving member can cooperate with the transmission mechanism to drive the lateral vane 301 to move in the reverse direction along a preset path, so that the lateral vane 301 covers the lateral air inlet 130 again. Based on the above settings of the forward active intake grille assembly 2 and the lateral active intake grille assembly 3, the forward vane 201 and the lateral vane 301 can be integrated into the front side shape of the vehicle body 100 when no internal and external air exchange is required, achieving visual hiding, thereby improving the visual effect and avoiding the problem of poor appearance and limited shape due to too many exposed holes on the front side of the vehicle body 100. In addition, since the lateral active intake grille assembly 3 adopts an outward-opening method, and this method is easy to use the driving device and the transmission mechanism behind the lateral vane 301 to provide support for the lateral vane 301, the structural strength of the front part of the vehicle body 100 can be maintained to a certain extent, and the problem of lack of stiffness, strength and manufacturing feasibility of the front part of the vehicle body 100 caused by all active intake grilles rotating towards the inside of the vehicle body 100 can be avoided.

[0066] Based on the above settings, taking a flying car as an example of a means of transportation, a heat dissipation strategy for this intake grille structure is proposed as follows:

[0067] When the flying car is in the idle or normal driving condition and the temperature of the positions such as the cabin inside the vehicle body 100 is relatively low, neither the forward active intake grille assembly 2 nor the lateral active intake grille assembly 3 is opened. At this time, only the normally open intake grille 1 can meet the heat dissipation requirements. When the flying car is in the driving process and the land vehicle body needs to charge the flying vehicle body, the heat dissipation demand inside the vehicle body 100 increases. At this time, the forward active intake grille assembly 2 drives the forward blades 201 to move towards the inside of the vehicle body 100, so that the forward air inlet 120 is opened, enabling external air to enter the inside of the vehicle body 100 simultaneously from the bottom air inlet 110 and the forward air inlet 120, thereby improving the heat dissipation effect. At the same time, it also complies with the regulatory requirement that the intake grille that opens and closes during driving can only move inward to open. When the flying car is in the parked state and the land vehicle body needs to charge the flying vehicle body, the heat dissipation demand doubles. At this time, with the forward air inlet 120 opened, the lateral active intake grille assembly 3 also drives the lateral blades 301 to move towards the outside of the vehicle body 100, so that the lateral air inlet 130 is opened accordingly, enabling external air to enter the inside of the vehicle body 100 simultaneously from the bottom air inlet 110, the forward air inlet 120, and the lateral air inlet 130, thereby greatly improving the heat dissipation effect. Thus, it not only meets the heat dissipation requirements of the flying car but also complies with the regulatory requirement that the intake grille that moves outward to open can only open and close under the parked condition. Preferably, a heat dissipation device is also installed inside the vehicle body 100. When at least part of the lateral air inlet 130 is opened, the heat dissipation device is used to actively suck external air into the inside of the vehicle body 100 through the lateral air inlet 130, enabling the lateral air inlet 130 to meet the air circulation requirements with a relatively small opening amplitude, that is, the lateral blades 301 do not need to move a large distance, thereby providing a technical basis for the miniaturization and lightweight design of the corresponding driving components and transmission mechanisms in the lateral active intake grille assembly 3.

[0068] It can be understood that when this intake grille structure is applied to other transportation vehicles, differential heat dissipation strategies can also be formulated according to the actual situation. By flexibly controlling the opening and closing of the forward active intake grille assembly 2 and the lateral active intake grille assembly 3, different heat dissipation requirements inside the vehicle body 100 under different working conditions can be met, which will not be elaborated here.

[0069] As can be seen, for the intake grille structure provided in this embodiment, a normally open intake grille 1, a forward active intake grille assembly 2, and a lateral active intake grille assembly 3 are provided at the front of the vehicle body 100. Among them, the forward active intake grille assembly 2 and the lateral active intake grille assembly 3 can be selectively opened or closed according to actual heat dissipation requirements, thus providing a structural basis for formulating differentiated heat dissipation strategies. In addition, when the forward active intake grille assembly 2 and the lateral active intake grille assembly 3 are in the closed state, the forward blades 201 of the forward active intake grille assembly 2 cover the forward air inlet 120 and are integrated with the shape of the front side of the vehicle body 100. The lateral blades 301 of the lateral active intake grille assembly 3 also cover the lateral air inlet 130 and are integrated with the shape of the front side of the vehicle body 100, achieving a hidden intake grille effect and avoiding the problem of poor appearance of the front part of the vehicle body 100 caused by the continuous exposure of the air inlet. Therefore, while meeting the heat dissipation requirements, the visual effect and sensory quality of the front part of the vehicle body 100 are improved. In addition, since the lateral active intake grille assembly 3 adopts an outward-opening method, this method is easy to use the driving device and transmission mechanism behind the lateral blades 301 to provide support for the lateral blades 301. Therefore, the structural strength of the front part of the vehicle body 100 can be maintained to a certain extent, avoiding the problems of lack of stiffness, strength, and manufacturing feasibility of the front part of the vehicle body 100 caused by all active intake grilles rotating towards the inside of the vehicle body 100.

[0070] Optionally, referring to Figures 1 to 6 , the front part of the vehicle body 100 has a front outer profile (not shown in the figure) and a side outer profile (not shown in the figure). The dividing line between the front outer profile and the side outer profile is a styling dividing line (not shown in the figure);

[0071] The outer side surface of the forward blade 201 is coplanar with the front outer profile, and one side edge of the forward blade 201 facing the lateral blade 301 is collinear with the styling dividing line.

[0072] Optionally, referring to Figures 1 to 6 , the outer side surface of the lateral blade 301 is coplanar with the side outer profile, and one side edge of the lateral blade 301 facing the forward blade 201 is collinear with the styling dividing line.

[0073] Illustratively, the front outer surface faces directly forward of the vehicle body 100, the side outer surfaces face the left front and the right front of the vehicle body 100, and the left and right sides of the front outer surface respectively form a styling dividing line. When the outer side surface of the front vane 201 is coplanar with the front outer surface, and the left and right side edges of the front vane 201 are respectively collinear with the two styling dividing lines, the front vane 201 can be integrated with the front part of the vehicle body 100 in terms of styling features, avoiding the front vane 201 protruding or concaving relative to the front side surface of the vehicle body 100, so that it is difficult for users to visually perceive the existence of the front active intake grille assembly 2; Similarly, when the outer side surface of the side vane 301 is coplanar with the side outer surface, and the corresponding side edges of the side vane 301 are respectively collinear with the two styling dividing lines, the side vane 301 can be integrated with the front part of the vehicle body 100 in terms of styling features, avoiding the side vane 301 protruding or concaving relative to the front side surface of the vehicle body 100, so that it is difficult for users to visually perceive the existence of the side active intake grille assembly 3. Based on the above settings, the visual effect of the front part of the vehicle body 100 can be further improved.

[0074] Optionally, referring to Figures 7 to 12 , the side active intake grille assembly 3 includes a side driving device 302 and a side active connecting rod 303; the side driving device 302 is installed inside the vehicle body 100 and above the front intake port 120, the first end of the side active connecting rod 303 is connected to the side driving device 302, and the second end of the side active connecting rod 303 is connected to the inner side surface of the side vane 301;

[0075] The side driving device 302 is configured to drive the side active connecting rod 303 to rotate about the first side axis 3001, so as to drive the side vane 301 to move outward of the vehicle body 100 to open at least part of the front intake port 120, or drive the side vane 301 to move inward of the vehicle body 100 to cover the side intake port 130.

[0076] Specifically, the side driving device 302 may include a motor and a matching reduction mechanism. The first end of the side active connecting rod 303 is higher than the second end. The second end of the side active connecting rod 303 can be hinged or fixedly connected to the inner side surface of the side vane 301, and the first side axis 3001 can extend in the horizontal direction. Based on the above settings, the side driving device 302 can drive the side vane 301 to move through the side active connecting rod 303 without blocking the side intake port 130, so as to open or close the side intake port 130 according to the heat dissipation requirements; and since the second end of the side active connecting rod 303 is connected to the inner side surface of the side vane 301, it can provide a supporting effect on the side vane 301 in the normal direction, thereby improving the position and structural stability of the side vane 301.

[0077] Optionally, referring to Figures 7 to 12, the lateral active air intake grille assembly 3 further includes a lateral driven link 304; the second end of the lateral active link 303 is hinged to the inner side surface of the lateral blade 301 around the second lateral axis 3002, the first end of the lateral driven link 304 is hinged to the vehicle body 100 around the third lateral axis 3003, and the second end of the lateral driven link 304 is hinged to the inner side surface of the lateral blade 301 around the fourth lateral axis 3004; the first lateral axis 3001, the second lateral axis 3002, the third lateral axis 3003, and the fourth lateral axis 3004 are spaced apart and parallel to each other.

[0078] When the lateral active link 303 and the lateral blade 301 are connected by a hinged manner, by setting the lateral driven link 304, the position stability of the lateral blade 301 can be maintained, and the lateral blade 301 can be prevented from rotating independently relative to the lateral active link 303; at the same time, since the second end of the lateral driven link 304 is hinged to the inner side surface of the lateral blade 301, the lateral driven link 304 can provide another support point for the lateral blade 301, and can jointly support the lateral blade 301 in the normal direction with the lateral active link 303, thereby further improving the position and structural stability of the lateral blade 301.

[0079] Specifically, such as Figures 7 to 12As shown, both the lateral active link 303 and the lateral driven link 304 can be H-shaped links. The lateral active link 303 and the lateral driven link 304 are arranged at intervals in the vertical direction. The lateral active link 303 can be arranged above the lateral driven link 304. The second end of the lateral active link 303 is hinged to the upper side of the lateral blade 301, and the second end of the lateral driven link 304 is hinged to the lower side of the lateral blade 301. The first lateral axis 3001, the second lateral axis 3002, the third lateral axis 3003, and the fourth lateral axis 3004 are connected to each other. 04 can extend in the horizontal direction, so as to ensure that the lateral active link 303 and the lateral driven link 304 can stably rotate around the horizontal axis, so as to stably drive the lateral blade 301 to move along the preset path and realize the opening and closing of the lateral air inlet 130; in addition, based on the fact that the lateral active link 303 and the lateral driven link 304 are arranged in an interval manner in the vertical direction, the size of the lateral active air intake grille assembly 3 in the horizontal direction can be compressed to the greatest extent, thereby reserving space for the setting of other devices and modules inside the vehicle body 100. And because the lateral active link 303 and the lateral driven link 304 can support the lateral blade 301 behind the lateral blade 301, when the lateral blade 301 completely covers the front air inlet 120, when the user presses inward or slightly bends the lateral blade 301, it will not cause the lateral blade 301 to move significantly relative to the vehicle body 100, thereby ensuring that the user can hardly detect the existence of the lateral blade 301 by touch, thereby further improving the concealment of the lateral active air intake grille assembly 3.

[0080] Preferably, the hinged parts between the lateral active link 303 and the lateral blade 301, and the hinged parts between the lateral driven link 304 and the lateral blade 301 are evenly arranged in the vertical direction. This can solve the problem of uniform force on the lateral blade 301, and the performance requirements such as structural strength of the lateral blade 301 during the opening and closing process and the static stage can be met with a streamlined and lightweight structure.

[0081] Optionally, refer to Figures 7 to 12 The lateral active air intake grille assembly 3 also includes a lateral grille frame 305, which is connected to the vehicle body 100, the lateral driving device 302 is installed on the lateral grille frame 305, and the first end of the lateral driven connecting rod 304 is hinged to the lateral grille frame 305 around the third lateral axis 3003.

[0082] Specifically, the lateral grille frame 305 serves as a transfer structure between the lateral driving device 302, the lateral driven link 304 and the vehicle body 100, solving the problem that it is not convenient to directly install the lateral driving device 302 and the lateral driven link 304 on the vehicle body 100; in addition, the lateral grille frame 305 can form an integrated lateral active intake grille module with the lateral driving device 302, the lateral active link 303 and the lateral driven link 304, which can facilitate the direct installation of the module on different vehicle bodies 100 subsequently, thus improving the assembly efficiency.

[0083] Preferably, the lateral grille frame 305 can be connected to components with relatively high structural strength such as the front bumper of the vehicle body 100 by means of threaded fasteners. The number of connection points can be set according to actual needs and evenly arranged on the lateral grille frame 305 to improve the structural stability of the lateral active intake grille assembly 3 and reduce unnecessary shaking.

[0084] Optionally, referring to Figures 7 to 12 , the lateral blade 301 includes a lateral outer vane 3011 and a lateral inner vane 3012. The inner side surface of the lateral outer vane 3011 is attached to the outer side surface of the lateral inner vane 3012. The second end of the lateral active link 303 is hinged to the inner side surface of the lateral inner vane 3012 around the second lateral axis 3002, and the second end of the lateral driven link 304 is hinged to the inner side surface of the lateral inner vane 3012 around the fourth lateral axis 3004; when the lateral blade 301 covers the lateral air inlet 130, the outer side surface of the lateral outer vane 3011 is coplanar with the lateral outer profile surface of the front part of the vehicle body 100.

[0085] By dividing the lateral blade 301 into the lateral outer vane 3011 and the lateral inner vane 3012, it is convenient to set the lateral outer vane 3011 and the lateral inner vane 3012 as different materials and structural forms respectively, so that the lateral outer vane 3011 can meet the styling requirements of the front side of the vehicle body 100 as much as possible, and at the same time, it can meet the structural and strength requirements when connecting the lateral inner vane 3012 with the lateral active link 303 and the lateral driven link 304.

[0086] Optionally, referring to Figures 7 to 12, the shortest straight-line distance between the first lateral axis 3001 and the second lateral axis 3002 is equal to the shortest straight-line distance between the third lateral axis 3003 and the fourth lateral axis 3004, and the shortest straight-line distance between the first lateral axis 3001 and the third lateral axis 3003 is equal to the shortest straight-line distance between the second lateral axis 3002 and the fourth lateral axis 3004. Based on this setting, the connection lines between the first lateral axis 3001, the second lateral axis 3002, the third lateral axis 3003, and the fourth lateral axis 3004 can form a parallelogram structure. In this way, during the process of the lateral active link 303 driving the lateral blade 301 to move, it can be ensured that the angle of the lateral blade 301 relative to the vehicle body 100 remains unchanged. For example, the lateral blade 301 can always be perpendicular to the ground during the movement, so that the opening and closing cooperation relationship between the lateral blade 301 and the lateral air inlet 130 can be more accurately controlled.

[0087] Based on the improvement of the intake grille structure in the present application, the size of the forward air inlet 120 is usually large. Therefore, the forward blade 201 usually needs to be set as a large blade structure with a large area. If the traditional form of driving the forward blade 201 to simply rotate around one side of the forward air inlet 120 by a driving device to achieve the opening and closing of the forward air inlet 120 is adopted, due to the long rotation lever arm, the torque requirement for the driving device is relatively high. And the driving device mainly composed of a motor is a selected component, and it usually cannot meet the relatively high torque requirement. As a result, the size of the forward air inlet 120 and the area of the forward blade 201 are limited and cannot better meet the needs of air circulation and heat dissipation.

[0088] To solve the above problems, the following embodiments are further proposed:

[0089] Please refer to Figures 13 to 17 , the forward active intake grille assembly 2 includes a forward drive assembly 22, a blade active link 202, and a blade driven link 203; the forward drive assembly 22 is installed inside the vehicle body 100; the first end of the blade active link 202 is hinged to the vehicle body 100 around the first blade link axis 2001, and the middle part of the blade active link 202 is connected to the forward drive assembly 22; the first end of the blade driven link 203 is hinged to the vehicle body 100 around the second blade link axis 2002; the upper side part of the forward blade 201 is hinged to the second end of the blade active link 202 around the third blade link axis 2003, and the lower side part of the forward blade 201 is hinged to the second end of the blade driven link 203 around the fourth blade link axis 2004; the forward blade 201 covers the forward air inlet 120; the forward drive assembly 22 is used to drive the blade active link 202 to rotate relative to the vehicle body 100, so as to drive the forward blade 201 to flip towards the inside of the vehicle body 100, thereby opening at least a part of the forward air inlet 120.

[0090] In this embodiment, the forward driving assembly 22 may include a driving member such as a motor and a corresponding transmission mechanism; in practical applications, it is only necessary to ensure that the forward driving assembly 22 can drive the blade active link 202 to rotate relative to the vehicle body 100 around the first blade link axis 2001 directly or indirectly, and the specific structure of the forward driving assembly 22 is not limited. In this embodiment, the upper side of the forward blade 201 is hinged and limited by the blade active link 202, and the lower side of the forward blade 201 is hinged and limited by the blade driven link 203. When the forward blade 201 covers the forward air inlet 120, the forward driving assembly 22 drives the blade active link 202 to rotate relative to the vehicle body 100, and then, with the cooperation of the blade driven link 203, the rotating blade active link 202 drives the forward blade 201 to turn inward, so that the forward blade 201 gradually deviates from the forward air inlet 120 by turning inward, thereby realizing the opening of the forward air inlet 120; when it is necessary to close the forward air inlet 120 subsequently, it is only necessary to drive the blade active link 202 to rotate in the reverse direction through the forward driving assembly 22 to drive the forward blade 201 to turn outward and cover the forward air inlet 120 again.

[0091] Compared with the traditional form of directly driving the forward blade 201 to rotate by a driving device, on the one hand, this embodiment shortens the rotation force arm through the transmission of the blade active link 202, thereby reducing the requirement for the driving torque of the forward driving assembly 22; on the other hand, the blade driven link 203 cooperates with the blade active link 202 to jointly limit the forward blade 201, so that the forward blade 201 can be integrally turned towards the inside of the vehicle body 100 according to a preset path, that is, the forward blade 201 can perform a certain degree of translation while rotating, rather than simply rotating around a fixed axis. At the same time, the blade driven link 203 can form a certain supporting effect on the lower side of the forward blade 201. The above multi-link driving form improves the traditional blade opening and closing driving method, shortens the rotation force arm, and can realize the stable turning of the forward blade 201 on the preset path with a lower requirement for the driving torque of the forward driving assembly 22, and then complete the opening and closing action of the forward air inlet 120, which can avoid the size of the forward air inlet 120 and the area of the forward blade 201 being restricted by the forward driving assembly 22, so that the size of the forward air inlet 120 and the area of the forward blade 201 can be increased, thus better meeting the design requirements of the vehicle.

[0092] Optionally, referring to Figures 13 to 17, the forward driving assembly 22 is disposed above the forward air inlet 120. The hinged portion between the first end of the blade driving link 202 and the vehicle body 100 is located above the forward air inlet 120. The blade driven link 203 is disposed on the left side and / or the right side of the forward air inlet 120. The forward blade 201 is configured to flip above the forward air inlet 120 under the drive of the blade driving link 202.

[0093] Illustratively, when the forward blade 201 covers the forward air inlet 120 and the forward blade 201 needs to be opened, the forward driving assembly 22 drives the second end of the blade driving link 202 to rotate upward relative to the vehicle body 100. The blade driving link 202 will drive the forward blade 201 to move upward. The forward blade 201 will drive the second end of the blade driven link 203 to rotate upward relative to the vehicle body 100. Thus, under the limiting action of the blade driving link 202 and the blade driven link 203, the forward blade 201 will rotate upward while translating upward relative to the vehicle body 100, thereby realizing the flipping of the forward blade 201. And because the hinged portion between the first end of the blade driving link 202 and the vehicle body 100 is located above the forward air inlet 120, the forward blade 201 can be flipped to a position above the forward air inlet 120 under the drive of the blade driving link 202 and will not block the forward air inlet 120. In addition, because the forward driving assembly 22 is disposed above the forward air inlet 120 and the blade driven link 203 is disposed on the left side and / or the right side of the forward air inlet 120, the forward driving assembly 22 and the blade driven link 203 will not block the forward air inlet 120. Based on the above settings, the forward driving assembly 22, the blade driving link 202, and the blade driven link 203 can be hidden, avoiding adverse effects of the above devices on the intake area of the forward air inlet 120, realizing the full opening of the forward air inlet 120, maximizing the intake area, avoiding adverse effects on the power performance of the vehicle, and further improving the sensory quality of the front part of the vehicle body 100 because the corresponding devices are hardly exposed.

[0094] Preferably, the forward driving assembly 22 is centrally disposed in the left-right direction of the vehicle body 100. In this way, the problem that the forward blade 201 drops due to its oversize can be avoided by the central placement of the forward driving assembly 22, and the problem of fatigue damage of the forward blade 201 and related devices under endurance conditions can be solved.

[0095] Optionally, refer to Figures 13 to 17, the first vane connecting rod axis 2001, the second vane connecting rod axis 2002, the third vane connecting rod axis 2003, and the fourth vane connecting rod axis 2004 are arranged at intervals and are pairwise parallel; more specifically, the first vane connecting rod axis 2001, the second vane connecting rod axis 2002, the third vane connecting rod axis 2003, and the fourth vane connecting rod axis 2004 can all extend along the horizontal direction, so as to ensure that the vane driving connecting rod 202, the vane driven connecting rod 203, and the forward vane 201 can all rotate stably around the horizontal axis, so that the forward vane 201 can stably flip and realize the opening and closing of the forward air inlet 120.

[0096] Optionally, referring to Figures 13 to 17 , the hinge parts between the first end of the vane driving connecting rod 202 and the vehicle body 100 are arranged to be at least two and are evenly arranged in the left-right direction.

[0097] Optionally, referring to Figures 13 to 17 , the hinge parts between the first end of the vane driven connecting rod 203 and the vehicle body 100 are arranged to be at least two and are evenly arranged in the left-right direction.

[0098] Optionally, referring to Figures 13 to 17 , the hinge parts between the upper side of the forward vane 201 and the second end of the vane driving connecting rod 202 are arranged to be at least two and are evenly arranged in the left-right direction.

[0099] Optionally, referring to Figures 13 to 17 , the hinge parts between the lower side of the forward vane 201 and the second end of the vane driven connecting rod 203 are arranged to be at least two and are evenly arranged in the left-right direction.

[0100] Specifically, by arranging the hinge parts between the vehicle body 100, the vane driving connecting rod 202, the vane driven connecting rod 203, and the forward vane 201 to be at least two and evenly arranged in the left-right direction, the connection stability between the above components and the stability during the relative rotation process can be improved. Preferably, the number of the above hinge parts can be set to be an even number and symmetrically arranged with respect to the longitudinal central symmetry plane of the vehicle body 100 to ensure the overall balance of the vehicle while meeting the connection requirements.

[0101] Optionally, referring to Figures 13 to 17 , the hinge parts between the upper side of the forward vane 201 and the second end of the vane driving connecting rod 202 are arranged to be four and are located on the inner side surface of the forward vane 201.

[0102] For a traditional blade structure that rotates around a fixed axis, it is impossible to set a stop point behind the blade because the stop point will interfere with the normal rotation of the blade. As a result, there is no support behind the blade when it is in the fully closed state, which leads to a large deformation of the active intake grille of the vehicle during high-speed driving, a poor leakage rate, and a high power consumption / fuel consumption of the whole vehicle. Based on this problem, in this embodiment, the hinge portion between the blade active link 202 and the forward blade 201 is arranged on the inner side of the forward blade 201 (i.e., behind the forward blade 201). After the forward blade 201 is fully closed (i.e., after the forward blade 201 completely covers the forward air inlet 120), this hinge portion can serve as a fulcrum and support the forward blade 201 from behind, thereby reducing the deformation of the forward blade 201 and related components, and thus reducing the leakage rate of the forward air inlet 120 and the power consumption / fuel consumption of the whole vehicle. More specifically, when four hinge portions between the upper side of the forward blade 201 and the second end of the blade active link 202 are arranged evenly in the left-right direction, the forward blade 201 can be divided into four relatively uniform parts in the length direction of the forward blade 201 (i.e., the left-right direction of the vehicle body 100), thereby improving the movement consistency and force uniformity of the forward blade 201 in its length direction.

[0103] Optionally, referring to Figures 13 to 17 , the forward active intake grille assembly 2 further includes a forward grille frame 207. The forward grille frame 207 is connected to the vehicle body 100. The forward drive assembly 22 is installed on the forward grille frame 207. The first end of the blade active link 202 is hinged to the forward grille frame 207 around the first blade link axis 2001, and the first end of the blade driven link 203 is hinged to the forward grille frame 207 around the second blade link axis 2002.

[0104] The forward grille frame 207, as a transfer structure between the forward drive assembly 22, the blade active link 202, the blade driven link 203 and the vehicle body 100, solves the problem that it is not convenient to directly install the forward drive assembly 22, the blade active link 202 and the blade driven link 203 on the vehicle body 100. In addition, the forward grille frame 207 can form an integrated forward active intake grille module with the forward drive assembly 22, the blade active link 202, the blade driven link 203 and the forward blade 201, which can facilitate the subsequent direct installation of this module on different vehicle bodies 100, thereby improving the assembly efficiency.

[0105] Optionally, referring to Figures 13 to 17, a limiting stop 2071 is provided at the lower side of the front grille frame 207; when the front blade 201 covers the front air inlet 120, the lower edge of the front blade 201 is located in front of the limiting stop 2071, and the limiting stop 2071 is used to block the backward movement of the lower edge of the front blade 201; when the front blade 201 is flipped towards the inner side of the vehicle body 100 driven by the blade active connecting rod 202, the lower edge of the front blade 201 moves upward from bottom to above the limiting stop 2071.

[0106] Since the front blade 201 in this application does not adopt the traditional opening and closing form of rotating around a fixed axis, but performs a certain degree of translation while rotating around the corresponding axis, a blocking point can be provided behind the front blade 201 to form a supporting effect on the front blade 201 in the closed state. Specifically, a connecting bracket can be provided at the lower side of the front grille frame 207, and the vertical side plate portion of the connecting bracket constitutes the limiting stop 2071, and the limiting stop 2071 can form a blocking point; when the front blade 201 in the open state is flipped to the closed state under the combined action of the blade active connecting rod 202 and the blade driven connecting rod 203, the lower edge of the front blade 201 can move downward from top to in front of the limiting stop 2071, so that the limiting stop 2071 can be used to form a supporting effect on the lower side of the front blade 201, so as to further reduce the deformation amount of the front blade 201 and related devices, and thus further reduce the leakage rate of the front air inlet 120 and the power consumption / fuel consumption of the whole vehicle; and when the front blade 201 needs to be opened, the front blade 201 is flipped under the combined action of the blade active connecting rod 202 and the blade driven connecting rod 203, and the lower edge of the front blade 201 can move upward from bottom to above the limiting stop 2071 without interfering with the limiting stop 2071.

[0107] Based on the structural form of supporting and limiting the upper side of the front blade 201 by using the hinge portion between the upper side of the front blade 201 and the second end of the blade active connecting rod 202, and supporting and limiting the lower side of the front blade 201 by using the limiting stop 2071 in the above embodiment, in practical applications, when the area of the front blade 201 is increased by 50% compared with the traditional blade structure, its leakage rate can be as low as 1.5%.

[0108] Optionally, referring to Figures 13 to 17, the forward vane 201 includes a forward outer vane plate 2011 and a forward inner vane plate 2012. The inner side surface of the forward outer vane plate 2011 is attached to the forward inner vane plate 2012. The upper side portion of the forward inner vane plate 2012 is hinged to the second end of the vane driving link 202 around the third vane link axis 2003, and the lower side portion of the forward inner vane plate 2012 is hinged to the second end of the vane driven link 203 around the fourth vane link axis 2004. When the forward vane 201 covers the forward air inlet 120, the outer side surface of the forward outer vane plate 2011 is coplanar with the forward outer profile surface of the front part of the vehicle body 100.

[0109] By dividing the forward vane 201 into the forward outer vane plate 2011 and the forward inner vane plate 2012, it is convenient to set the forward outer vane plate 2011 and the forward inner vane plate 2012 as different materials and structural forms respectively, so that the forward outer vane plate 2011 can meet the shaping requirements of the front side of the vehicle body 100 as much as possible, and at the same time, the structural and strength requirements for the connection between the forward inner vane plate 2012 and the vane driving link 202 and the vane driven link 203 can be met.

[0110] Based on the improvement of the present application on the forward active air intake grille assembly 2, in practical applications, when the forward drive assembly 22 drives the forward vane 201 to open and close in a traditional manner, there is a problem that the shaking amount of the forward vane 201 is relatively large. This not only has an adverse impact on the normal driving of the vehicle and the air exchange operation, but also reduces the durability and reliability of devices such as the forward vane 201 due to excessive shaking. And more importantly, the forward active air intake grille assembly 2 needs to work and has process gears during the driving and stationary processes of the vehicle, that is, other gears need to be set during the movement process of the forward vane 201 outside the two states of fully open and fully closed, and the excessive shaking amount of the forward vane 201 will restrict the normal application of the forward active air intake grille assembly 2 of the present application in the process gears.

[0111] The R & D personnel of the present application further found through research that in order to absorb the dimensional changes caused by manufacturing, assembly tolerances and thermal expansion and contraction phenomena, drive devices such as motors usually reserve a certain gap, which results in at least a virtual angle of 2° - 3° at the output end of the drive device itself. And the transmission mechanism between the drive device and the forward vane 201 will multiply and amplify this virtual angle based on the lever principle, resulting in a relatively large shaking amount of the forward vane 201, which not only has poor sensory quality, but also has an adverse impact on the durability, fatigue, abnormal noise and other performances of the forward vane 201 and related devices.

[0112] To solve the above problems, the following embodiments are further proposed:

[0113] Please refer to Figures 13 to 17, the forward active intake grille assembly 2 further includes a forward drive device 204, a forward active link 205, a forward driven link 206, and a blade assembly 21; the forward drive device 204 is installed inside the vehicle body 100; the first end of the forward active link 205 is connected to the forward drive device 204; the first end of the forward driven link 206 is hinged to the second end of the forward active link 205 about the second forward axis 2006; the blade assembly 21 has a forward blade 201, and the forward blade 201 covers the forward air inlet 120; the blade assembly 21 is hinged to the vehicle body 100 about the first blade link axis 2001, and the blade assembly 21 is hinged to the second end of the forward driven link 206 about the third forward axis 2007.

[0114] The forward drive device 204 is used to drive the forward active link 205 to rotate about the first forward axis 2005, so as to drive the blade assembly 21 to flip towards the inner side of the vehicle body 100 through the forward driven link 206, thereby opening at least a part of the forward air inlet 120; the first angular velocity of the forward active link 205 relative to the vehicle body 100 is greater than the second angular velocity of the blade assembly 21 relative to the vehicle body 100.

[0115] In this embodiment, the forward drive device 204 may include a motor and a matching reduction mechanism. The blade assembly 21 may only include the forward blade 201, or may also include the forward blade 201 and a transmission mechanism used in conjunction with the forward blade 201; wherein, when the blade assembly 21 only includes the forward blade 201, the forward blade 201 may be respectively hinged to the vehicle body 100 and the second end of the forward driven link 206 directly or indirectly, and the two hinge parts are arranged at intervals; and when the blade assembly 21 includes the forward blade 201 and a transmission mechanism used in conjunction with the forward blade 201, the transmission mechanism may refer to the blade active link 202 and the blade driven link 203 in the above embodiment. At this time, the blade active link 202 is respectively hinged to the vehicle body 100 and the second end of the forward driven link 206, and the two hinge parts are arranged at intervals.

[0116] Based on the above settings, if the shortest connecting line between the two hinge parts of the blade assembly 21 is used as a rod body, a crank-rocker mechanism can be formed between this rod body and the forward active link 205 and the forward driven link 206. Among them, this rod body (subsequently referred to as the blade assembly 21) is used as the rocker, the forward active link 205 is used as the crank, and the forward driven link 206 is used as the connecting rod; thus, based on the structural characteristics and action principle of the crank-rocker mechanism, by reasonably setting the length relationship between the crank, the connecting rod, and the rocker in this crank-rocker mechanism, the differential speed between the crank and the rocker can be achieved, that is, the first angular velocity of the forward active link 205 relative to the vehicle body 100 is greater than the second angular velocity of the blade assembly 21 relative to the vehicle body 100.

[0117] Based on the above technical settings, taking Figures 13 to 16 as an example, the present solution will be further described. Specifically, the state where the forward blade 201 completely covers the forward air inlet 120 is regarded as the closed state, and the state where the forward blade 201 is completely opened and the forward air inlet 120 is completely opened is regarded as the open state. During the process of switching from the closed state to the open state or from the open state to the closed state, the angle that the blade assembly 21 needs to rotate is α, and the angle that the forward active link 205 needs to rotate driven by the forward drive device 204 is β. Since the first rotational angular velocity of the forward active link 205 is greater than the second rotational angular velocity of the blade assembly 21, α < β; thus, it can be seen that the rotational angle ratio between the blade assembly 21 and the forward active link 205 = α / β < 1, that is, after the driving force of the forward drive device 204 is transmitted to the blade assembly 21 through the forward active link 205 and the forward driven link 206 of this embodiment, the rotational angle of the blade assembly 21 will be reduced relative to the initial rotational angle of the forward drive device 204 in a certain proportion; based on this principle, the virtual angle of the forward drive device 204 will also be reduced in this proportion. After the virtual angle of the forward drive device 204 is reduced, the shaking amplitude of the forward blade 201 caused by this virtual angle will also be reduced accordingly, effectively solving the problem of the excessive shaking amount of the forward blade 201 having an adverse impact on the normal driving of the vehicle and the air exchange operation, improving the durability and reliability of devices such as the forward blade 201, enhancing the sensory quality, and providing a structural basis for the normal application of the forward active air intake grille assembly 2 in the process gear position.

[0118] As an example, when the first forward axis 2005, the second forward axis 2006, the third forward axis 2007, and the first blade link axis 2001 are spaced apart and pairwise parallel, the shortest straight-line distance between the first blade link axis 2001 and the third forward axis 2007 is greater than the shortest straight-line distance between the first forward axis 2005 and the second forward axis 2006, and the shortest straight-line distance between the second forward axis 2006 and the third forward axis 2007 is greater than the shortest straight-line distance between the first forward axis 2005 and the second forward axis 2006; based on this setting method, it can be achieved that the first rotational angular velocity of the forward active link 205 relative to the vehicle body 100 is greater than the second rotational angular velocity of the blade assembly 21 relative to the vehicle body 100, and the difference between the first rotational angular velocity and the second rotational angular velocity can be maximized, thereby maximizing the reduction of the virtual angle.

[0119] Optionally, referring to Figures 13 to 17, the ratio of the second rotational angular velocity to the first rotational angular velocity is 0.3 to 0.45; based on this setting, in practical applications, when the forward active intake grille assembly 2 switches from the closed state to the open state, or from the open state to the closed state, if the rotation angle of the forward active link 205 is 135°, the corresponding rotation angle of the blade assembly 21 is 56°. In this way, a rotation angle change ratio of approximately 3:1 can be achieved, and the virtual angle of the forward drive device 204 can be approximately reduced to one-third of the original, thereby reducing the sway of the forward blade 201 and improving the durability and reliability of components such as the forward blade 201.

[0120] Optionally, referring to Figures 13 to 17 , the blade assembly 21 includes a blade active link 202 and a blade driven link 203; the first end of the blade active link 202 is hinged to the vehicle body 100 around the first blade link axis 2001, the middle of the blade active link 202 is hinged to the second end of the forward driven link 206 around the third forward axis 2007, and the first end of the blade driven link 203 is hinged to the vehicle body 100 around the second blade link axis 2002; the upper side of the forward blade 201 is hinged to the second end of the blade active link 202 around the third blade link axis 2003, and the lower side of the forward blade 201 is hinged to the second end of the blade driven link 203 around the fourth blade link axis 2004; the blade active link 202 is used to drive the forward blade 201 to flip towards the inside of the vehicle body 100 under the drive of the forward driven link 206.

[0121] In this embodiment, the blade assembly 21 is further defined. For the cooperation relationship between the blade active link 202, the blade driven link 203 and the forward blade 201, please refer to the above embodiment and will not be elaborated here. Based on the solution of this embodiment, a four-bar linkage can be formed among the forward active link 205, the forward driven link 206, the blade active link 202, and the blade driven link 203; in the actual application process, the forward drive device 204 first drives the forward active link 205 to rotate around the first forward axis 2005, and the rotating forward active link 205 will drive the blade active link 202 to rotate around the first blade link axis 2001 through the forward driven link 206. Thus, the blade active link 202 can cooperate with the blade driven link 203 to drive the forward blade 201 to flip, thereby realizing the opening and closing of the forward air inlet 120.

[0122] Based on the four-bar linkage mechanism of this embodiment, on the one hand, it can achieve the stable flipping of the forward blade 201 on the preset path with relatively low requirements for the driving torque of the forward driving device 204, and then complete the opening and closing actions of the forward air inlet 120. It can avoid the limitations of the size of the forward air inlet 120 and the area of the forward blade 201 by the forward driving assembly 22, enabling the size of the forward air inlet 120 and the area of the forward blade 201 to be increased, so as to better meet the design requirements of the vehicle. On the other hand, it can reduce the virtual angle of the forward driving device 204 by a certain proportion through the transmission mechanism composed of the forward active link 205 and the forward driven link 206, so that the shaking amplitude of the forward blade 201 caused by the virtual angle is reduced accordingly. Thus, it can effectively solve the problem that the excessive shaking of the forward blade 201 has an adverse impact on the normal driving and air exchange operation of the vehicle, improve the durability and reliability of components such as the forward blade 201, enhance the sensory quality, and provide a structural basis for the normal application of the forward active air intake grille assembly 2 in the process gear position.

[0123] Optionally, referring to Figures 13 to 17 , the first blade link axis 2001, the second blade link axis 2002, the third blade link axis 2003, the fourth blade link axis 2004, the first forward axis 2005, the second forward axis 2006, and the third forward axis 2007 are spaced apart and parallel to each other in pairs; more specifically, the first blade link axis 2001, the second blade link axis 2002, the third blade link axis 2003, the fourth blade link axis 2004, the first forward axis 2005, the second forward axis 2006, and the third forward axis 2007 can all extend along the horizontal direction. In this way, it can ensure that the forward active link 205, the forward driven link 206, the blade active link 202, the blade driven link 203, and the forward blade 201 can all rotate stably and smoothly around the horizontal axis, so that the forward blade 201 can stably flip and realize the opening and closing of the forward air inlet 120.

[0124] Optionally, referring to Figures 13 to 17 , the first blade link axis 2001 is located above the first forward axis 2005; in this way, the relative positions among the blade active link 202, the forward active link 205, and the forward driven link 206 can be reasonably arranged, so that the forward active link 205 can stably drive the blade active link 202 to rotate upward or downward as Figure 14 and Figure 16 shown when rotating upward or downward, so that the blade active link 202 can stably drive the forward blade 201 to flip along the preset path.

[0125] Optionally, referring to Figures 13 to 17, the forward grille frame 207 can be connected to the front bumper of the vehicle body 100 (not shown in the figure) by means of threaded fasteners. The number of locking installation points between the forward grille frame 207 and the front bumper can be set to multiple according to actual needs and evenly arranged on the forward grille frame 207. In this way, the stiffness of the forward grille frame 207, the forward drive assembly 22, the blade active link 202, and the blade driven link 203 can be enhanced through more fixing points between the forward grille frame 207 and the front bumper, ensuring the rigidity of the driving force transmission path, reducing the shaking caused by problems such as deformation, bending, and torsion of the above-mentioned devices, further improving the durability and reliability of devices such as the forward blade 201 and enhancing the sensory quality, and providing a structural basis for the normal application of the forward active intake grille assembly 2 in the process gear position.

[0126] Optionally, referring to Figures 13 to 17 , the hinge parts between the first end of the forward driven link 206 and the second end of the forward active link 205 are set to at least two and evenly arranged on the left and right sides of the forward drive device 204.

[0127] Optionally, referring to Figures 13 to 17 , the hinge parts between the blade assembly 21 and the second end of the forward driven link 206 are set to at least two and evenly arranged on the left and right sides of the forward drive device 204; more specifically, the hinge parts between the middle of the blade active link 202 and the second end of the forward driven link 206 are set to at least two and evenly arranged on the left and right sides of the forward drive device 204.

[0128] Optionally, referring to Figures 13 to 17 , the hinge parts between the blade assembly 21 and the vehicle body 100 are set to at least two and evenly arranged in the left - right direction; more specifically, the hinge parts between the first end of the blade active link 202 and the vehicle body 100 are set to at least two and evenly arranged on the left and right sides of the forward drive device 204.

[0129] By setting the hinge parts between the vehicle body 100, the forward active link 205, the forward driven link 206, and the blade assembly 21 to at least two and arranged on the left and right sides of the forward drive device 204, on the one hand, the connection stability between the above - mentioned components can be enhanced by increasing the hinge parts, and on the other hand, the forces on the left and right sides of the forward drive device 204 of the above - mentioned components can be made uniform, so as to improve the stability when the forward drive device 204 drives the above - mentioned components to rotate, and ensure the overall balance of the vehicle while meeting the connection requirements.

[0130] Optionally, referring to Figures 13 to 17The blade assembly 21 also includes an elastic member (not shown in the figure), one end of the elastic member is connected to the blade active link 202, and the other end of the elastic member is connected to the vehicle body 100; when the blade active link 202 drives the forward blade 201 to flip toward the inner side of the vehicle body 100, the elastic member is used to apply an elastic force to the blade active link 202 to prevent the blade active link 202 from rotating relative to the vehicle body 100.

[0131] Specifically, the elastic member may be a spring, an elastic colloid, etc., which is not limited here. During the opening process of the forward blade 201, the elastic force applied by the elastic member to the blade active link 202 may be a pressing force or a pulling force, which is intended to prevent the blade active link 202 from continuing to rotate, so as to limit the degree of freedom of the blade active link 202 in the opening direction of the forward blade 201, thereby further reducing the shaking of the forward blade 201 in the process position, thereby further improving the durability and reliability of the forward blade 201 and other devices.

[0132] See also Figures 19 to 21 , the forward driving device 204 has a forward driving chip 2041 and a forward driving actuator 2042, and the lateral driving device 302 has a lateral driving actuator 3021; the forward driving chip 2041 is electrically connected to the forward driving actuator 2042 and the lateral driving actuator 3021, the forward driving actuator 2042 is connected to the forward blade 201 through the connecting rod mechanism in the above embodiment, and the lateral driving actuator 3021 is connected to the lateral blade 301 through the connecting rod mechanism in the above embodiment;

[0133] The forward driving chip 2041 is used to send a forward driving signal to the forward driving actuator 2042 to trigger the forward driving actuator 2042 to drive the forward blade 201 to move; and the forward driving chip 2041 is used to send a lateral driving signal to the lateral driving actuator 3021 after the forward blade 201 moves to trigger the lateral driving actuator 3021 to drive the lateral blade 301 to move.

[0134] For existing vehicles using active air intake grilles, Figure 18 As shown, it is generally adopted that each active air intake grille is equipped with a driving device, and the driving device specifically includes a motor, etc. Each driving device contains components such as a motor, an actuator, and a control chip. Each control chip is used to send a driving signal to the corresponding actuator to drive the corresponding blade of the active air intake grille to perform a corresponding opening or closing operation. If the number of active air intake grilles is large, the number of driving devices will increase accordingly, resulting in a significant increase in cost, and will put greater pressure on the overall power load and communication load of the vehicle.

[0135] Based on the above problems, Figure 19As shown in the figure, in this embodiment, the forward driving device 204 and the lateral driving device 302 are correspondingly set in a master-slave driving mode. Among them, the forward driving device 204 as the master driving device is configured with a forward driving chip 2041 and a forward driving actuator 2042, while the lateral driving device 302 as the slave driving device is only configured with a lateral driving actuator 3021. The forward driving chip 2041 of the forward driving device 204 can control the forward driving actuator 2042 and the lateral driving actuator 3021 in time-sharing manner. During the actual application process, please refer to Figure 20 , when it is necessary to open or close the forward vane 201 and the lateral vane 301, the forward driving chip 2041 first sends a forward driving signal to the forward driving actuator 2042, and then judges whether the forward driving actuator 2042 has driven the forward vane 201 to perform the corresponding opening or closing operation through the corresponding linkage mechanism; when it is judged that the opening or closing operation of the forward vane 201 is completed, the forward driving chip 2041 then sends a lateral driving signal to the lateral driving actuator 3021 to drive the lateral vane 301 to perform the corresponding opening or closing operation; thus, the forward vane 201 and the lateral vane 301 can sequentially complete the corresponding opening or closing operations one after another. Based on this master-slave driving control strategy, on the one hand, the number of driving chips can be reduced, and the control of two active air intakes can be achieved only through one driving chip, thereby reducing the cost; on the other hand, the overall power consumption load and communication load pressure of the vehicle can be reduced by means of time-sharing control.

[0136] Optionally, referring to Figures 19 to 21 , the forward driving chip 2041 is used to send a forward fault detection signal to the forward driving actuator 2042 to obtain the fault information of the forward driving actuator 2042; and the forward driving chip 2041 is used to send a lateral fault detection signal to the lateral driving actuator 3021 after the forward driving actuator 2042 returns a fault-free signal to obtain the fault information of the lateral driving actuator 3021.

[0137] On the basis of the previous embodiment, this embodiment further applies the master-slave control strategy to the fault diagnosis of the active air intake grille. Specifically, as Figure 21As shown in the figure, after the forward driving chip 2041 sends a forward driving signal to the forward driving actuator 2042, the forward driving chip 2041 starts to determine whether the forward driving actuator 2042 can normally drive the forward blade 201 to perform corresponding opening or closing operations. If the forward blade 201 cannot be normally opened or closed, the fault information will be acquired by the forward driving chip 2041 and corresponding warning prompts and other operations will be performed; if the forward driving actuator 2042 can normally drive the forward blade 201 to open or close, the forward driving chip 2041 continues to determine whether the lateral driving actuator 3021 that receives the lateral driving signal can normally drive the lateral blade 301 to open or close; if the lateral blade 301 cannot be normally opened or closed, the fault information will also be acquired by the forward driving chip 2041 and corresponding warning prompts and other operations will be performed.

[0138] Based on the above settings, a driving chip can be used to identify faults in two active air intakes, and the fault identification operation is carried out in a time-sharing control manner, so as to reduce the overall power consumption load and communication load pressure of the vehicle.

[0139] Please refer to Figures 1 to 21 , this application also provides a vehicle, including a vehicle body 100 and the air intake grille structure in any of the above embodiments.

[0140] In this embodiment, the vehicle includes, but is not limited to, cars, trucks, and aircraft (including flying cars). For the specific settings of the air intake grille structure, please refer to the above embodiments. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, that is, a normally open air intake grille 1, a forward active air intake grille assembly 2, and a lateral active air intake grille assembly 3 are provided at the front of the vehicle body 100, and the forward active air intake grille assembly 2 and the lateral active air intake grille assembly 3 can be selectively opened or closed according to actual heat dissipation requirements, thus providing a structural basis for formulating a differentiated heat dissipation strategy; in addition, when the forward active air intake grille assembly 2 and the lateral active air intake grille assembly 3 are in the closed state, the forward blade 201 of the forward active air intake grille assembly 2 covers the forward air intake 120 and merges with the shape of the front side of the vehicle body 100, and the lateral blade 301 of the lateral active air intake grille assembly 3 also covers the lateral air intake 130 and merges with the shape of the front side of the vehicle body 100, achieving a hidden air intake grille effect and avoiding the problem of poor visual appearance of the front part of the vehicle body 100 caused by the continuous exposure of the air intake, thereby improving the visual effect and sensory quality of the front part of the vehicle body 100 while meeting the heat dissipation requirements.
