Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a sliding active air intake grille and a vehicle thereof. Background Technology

[0002] As the automotive industry increasingly demands energy conservation, emission reduction, and improved vehicle performance, active grille shutters are being used more and more widely in passenger vehicles. Active grille shutters automatically adjust the opening and closing degree of the grille based on vehicle driving conditions, such as vehicle speed and engine temperature, thereby optimizing vehicle aerodynamics, reducing wind resistance, reducing fuel consumption, and helping the engine reach its optimal operating temperature quickly, improving engine efficiency and reliability.

[0003] The rotary active grille uses a motor to drive blades to rotate around an axis, dynamically adjusting the air intake to the engine compartment. It closes during cold starts to quickly warm up the engine and opens during high-speed cruising to reduce wind resistance. However, in water-related conditions (such as driving through flooded areas during heavy rain), the water impact load acts on the connection between the blades and the motor, subjecting the motor to significant torque and increasing the risk of motor damage. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a sliding active air intake grille, which can reduce the risk of motor damage and enhance the vehicle's adaptability in complex road conditions.

[0005] This utility model also proposes a vehicle having the above-mentioned sliding active air intake grille.

[0006] According to a first aspect embodiment of the present invention, a sliding active air intake grille includes: A frame, including a substrate, wherein the substrate is provided with an air inlet; The blade is movably mounted on the frame, and the blade is located on one side of the base plate and can cover the air inlet; A drive device is connected to the blade and drives the blade to slide along the plane of the substrate to open or close the air inlet; The frame further includes a first limiting plate, which is located on the side of the blade away from the substrate. A guide groove is formed between the first limiting plate and the substrate, and part of the blade is located in the guide groove.

[0007] The sliding active air intake grille according to the present utility model embodiment has at least the following beneficial effects: Since the blades are slidably mounted on the frame, the guide rail groove can support the blades along the axial direction of the air intake. When wading through water, part of the water impact force acts directly on the frame, and the other part is transmitted to the frame through the blades, which reduces the force transmitted to the motor, reduces the risk of motor damage, and enhances the vehicle's adaptability in complex road conditions.

[0008] According to some embodiments of the present invention, the substrate is provided with a plurality of air inlets, the plurality of air inlets are spaced apart along the sliding direction of the blade, and the blade is provided with a plurality of shielding parts, each of the shielding parts being able to cover one air inlet individually.

[0009] According to some embodiments of the present invention, one end of the multiple shielding parts on the same side is connected as a whole by a connecting part, and the other end is a cantilever end.

[0010] According to some embodiments of the present invention, the first limiting plate is provided with a rolling part, the rolling part is rotatably connected to the first limiting plate, and the rolling part abuts against the side of the blade opposite to the substrate.

[0011] According to some embodiments of the present invention, there are multiple rolling parts, which are arranged along the sliding direction of the blade, and any two adjacent rolling parts abut against each other.

[0012] According to some embodiments of the present invention, two first limiting plates are provided on the same side of the blade, and an installation groove for accommodating the rolling part is formed between the two first limiting plates.

[0013] According to some embodiments of the present invention, the number of the blocking parts is three, and the connection position between the driving device and the blade is located at both ends of the sliding direction of the blade.

[0014] According to some embodiments of the present invention, the driving device includes a power mechanism and a slider. The slider is fixedly connected to the blade. The power mechanism drives the slider to move, thereby causing the blade to slide along the plane of the substrate.

[0015] According to some embodiments of the present invention, the frame further includes two second limiting plates, which are respectively located on both sides of the sliding direction of the blade. When the blade abuts against one of the second limiting plates, the blade closes the air inlet; when the blade abuts against the other second limiting plate, the blade opens the air inlet.

[0016] The vehicle according to the second aspect of the present invention includes the sliding active air intake grille of the first aspect of the present invention.

[0017] The vehicle according to the embodiments of the present invention has at least the following beneficial effects: by adopting the sliding active air intake grille of the first aspect embodiment of the present invention, the risk of motor damage is reduced and the adaptability of the vehicle in complex road conditions is enhanced.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Reference Figures 1 to 3 The sliding active air intake grille includes a frame, blades 200, and a drive unit. The frame includes a base plate 110, which has an air inlet 111. The frame is the basic load-bearing structure, and the air inlet 111 on the base plate 110 is the core channel for airflow. The blades 200 are movably mounted on the frame, located on one side of the base plate 110, and can cover the air inlet 111. The blades 200 directly control the air intake volume by sliding to cover or move away from the air inlet 111 (blocking airflow when fully closed, and allowing airflow when sliding open). The drive unit includes a motor 310, which is connected to the blades 200 through a transmission component and drives the blades 200 to slide along the plane of the base plate 110 to open or close the air inlet 111. The drive unit provides power to drive the blades 200 to slide along the plane of the base plate 110, completing the active control of the opening degree. The frame also includes a first limiting plate 120, which is located on the side of the blade 200 away from the substrate 110. A guide groove 121 is formed between the first limiting plate 120 and the substrate 110, and part of the blade 200 is located within the guide groove 121. That is, the blade 200 is sandwiched between the substrate 110 and the first limiting plate 120. The guide groove 121 provides bidirectional limiting for the blade 200, restricting the blade 200 from swaying in the direction perpendicular to the substrate 110 (the frame provides support for the blade 200), and constraining the sliding path of the blade 200 through the contour of the guide groove 121, ensuring that the blade 200 moves only directionally along the plane of the substrate 110 (avoiding offset and jamming).

[0026] Understandably, the wrapping constraint of the guide rail groove 121 on the blade 200 allows the blade 200 to experience more balanced forces during sliding, reducing swaying or deviation even under complex conditions such as water flow impact, thus lowering the risk of jamming. When the vehicle is wading through water, the high-pressure water flow impacts the leading edge of the blade 200. The blade 200 transmits the impact force to the guide rail groove 121 through the contact surface, and the impact force is ultimately distributed throughout the frame. Less force is transmitted to the drive unit, significantly reducing the risk of damage to the motor 310 caused by water impact.

[0027] Reference Figure 4 The substrate 110 is provided with a plurality of air inlets 111, which are spaced apart along the sliding direction of the blade 200. (Refer to...) Figure 5 The blade 200 is provided with multiple shielding portions 210, each shielding portion 210 capable of individually covering an air inlet 111. The base plate 110 includes multiple grille strips 140, which are arranged alternately with the air inlets 111. The grille strips 140 serve as a supporting frame, separating adjacent air inlets 111, thus ensuring the structural strength of the base plate 110 and enabling it to withstand higher dynamic loads. The width of the grille strips 140 is approximately equal to the width of the shielding portions 210. When the blade 200 opens the air inlet 111, the shielding portions 210 move to the rear side of the grille strips 140. During the vehicle's forward movement, the gas impact load mainly acts on the frame, effectively protecting the motor 310.

[0028] Reference Figure 5Multiple shielding parts 210 are connected at one end on the same side by a connecting part 220, and the other end is a cantilever end 221. That is, multiple shielding parts 210 are interconnected at one end by the connecting part 220, while the other ends are disconnected. Connecting the dispersed shielding parts 210 into a whole through the connecting part 220 makes the blade 200 a single part, ensuring the relative positional accuracy of each shielding part 210 and enhancing the overall structural rigidity of the blade 200. The blade 200 is injection molded as a whole. The shielding part 210 is fixed only on one side by the connecting part 220, and the other side is a cantilever end 221 (without a lateral connecting structure), giving the blade 200 a "unidirectional extension" characteristic in the molding die. The free state of the cantilever end 221 allows the mold to open smoothly in a single direction (such as parallel to the extension direction of the shielding part 210), eliminating the need for a complex core-pulling mechanism, reducing mold design difficulty and manufacturing costs, and reducing molding defects caused by undercuts (such as material shortages and tearing). The integrated connecting part 220 can act as a "mainstream branch" during injection molding, guiding the molten material to fill each shielding part 210 evenly, avoiding uneven filling caused by complex structure and improving product qualification rate. The free state of the cantilever end 221 gives it a certain "tolerance" during installation. For example, when the blade 200 is placed into the guide groove 121, the cantilever end 221 can deform slightly to adapt to the dimensional error of the frame (or, through its own slight deformation, to adapt to the flatness error between the blade 200 and the guide groove 121), avoiding assembly jamming caused by excessive rigidity; at the same time, the flexibility of the cantilever end 221 during sliding can reduce frictional interference with the frame and improve assembly smoothness.

[0029] In some other embodiments, each shield 210 can be moved individually to cover or expose the corresponding single air inlet 111. For example, when a small flow rate is required, only the middle air inlet 111 is opened; when a large flow rate is required, all three air inlets 111 are opened.

[0030] Reference Figure 2 The first limiting plate 120 is provided with a rolling part 400 (the rolling part 400 is a rotatable component such as a roller, ball, or shaft). The rolling part 400 is rotatably connected to the first limiting plate 120 and abuts against the side of the blade 200 facing away from the base plate 110. By providing the rolling part 400, the contact area between the blade 200 and the frame is reduced, and the resistance to overcome sliding friction is transformed into the rotation of the roller, which significantly reduces the torque requirement of the motor 310, thereby reducing energy consumption and improving the working efficiency and service life of the motor 310. Furthermore, the rolling part 400 makes the blade 200 open and close more smoothly, effectively avoiding jamming and improving the adjustment accuracy of the air intake grille. Due to the reduction in the torque requirement of the motor 310, the load on the motor 310 and related transmission components is reduced, the probability of failure is reduced, and the reliability of the entire air intake grille system is improved.

[0031] Reference Figure 2 and Figure 3 Multiple rolling parts 400 are arranged along the sliding direction of the blade 200, with any two adjacent rolling parts 400 abutting against each other. The rolling parts 400 are close together, meaning there are no gaps between them. When the blade 200 slides, its side facing away from the substrate 110 is always in contact with at least one rolling part 400. The rolling parts 400 sequentially contact and transmit force, preventing the blade 200 from being partially suspended due to excessive spacing between the rolling parts 400. The guide groove 121 constrains the displacement of the blade 200 from both sides, preventing jamming when the cantilever end 221 slides. The adjacent rolling parts 400 apply stable pressure from the vertical direction, so the force on the cantilever end 221 is mainly on the vertical surface of the blade 200, limiting its vertical warping. Furthermore, the stiffness of each shielding part 210 meets performance requirements, ensuring the overall stability of the blade 200.

[0032] Reference Figure 2 and Figure 4 Two first limiting plates 120 are provided on the same side of the blade 200, and a mounting groove 122 for accommodating the rolling part 400 is formed between the two first limiting plates 120. The rolling part 400 is connected to the two first limiting plates 120 respectively through a rotating shaft. The two first limiting plates 120 are provided on the same side of the blade 200 and are arranged opposite to each other, and the gap between them forms the mounting groove 122 for accommodating the rolling part 400. The mounting groove 122 defines a precise spatial range for the rolling part 400, preventing the rolling part 400 from shifting laterally when rotating or under the pressure of the blade 200. The mounting groove 122 formed by the two first limiting plates 120 extends in the same direction as the sliding direction of the blade 200, ensuring that the rotation direction of the rolling part 400 is completely matched with the movement direction of the blade 200 (the rolling direction is parallel to the sliding direction), and avoiding additional frictional resistance due to angular deviation.

[0033] If the width of a single blocking part 210 is too small, its contact area with the rolling part 400 will be significantly reduced. The pressing force of the rolling part 400 on the blade 200 will be concentrated in a narrow area, which may cause local deformation of the blocking part 210, resulting in a deviation of the sliding trajectory. (Refer to...) Figure 3 and Figure 5In this embodiment, the number of shielding parts 210 is three, which is relatively small. This allows for a larger width for each shielding part 210. When the cantilever end 221 contacts the rolling part 400, the rolling part 400 provides more stable support for the blade 200, resulting in a more uniform pressure distribution and reducing the risk of localized deformation. The connection points between the drive device and the blade 200 are located at both ends of the sliding direction of the blade 200. When the blade 200 slides, the simultaneous force applied to both ends ensures that the blade 200 moves "parallel" along the sliding direction, avoiding "deflection" caused by unilateral drive (such as excessive force on one end causing the blade 200 to tilt, resulting in misalignment between the shielding part 210 and the air inlet 111).

[0034] The driving device includes a power mechanism and a slider 320. The slider 320 is fixedly connected to the blade 200. The power mechanism drives the slider 320 to move, thereby causing the blade 200 to slide along the plane of the substrate 110. The slider 320 is an "intermediate carrier" for power transmission and is fixedly connected to the blade 200 (e.g., by bolts, clips, or integral molding). Its structure must be adapted to the connecting part 220 of the blade 200 to ensure connection rigidity (to avoid relative sliding during power transmission). The linear motion trajectory of the slider 320 is stable, and precise displacement control can be achieved through the power mechanism (e.g., a stepper motor 310) to ensure the positional accuracy of the blade 200's sliding and meet the precise alignment requirements of the shielding part 210 and the air inlet 111.

[0035] Reference Figures 1 to 3 In this embodiment, the power mechanism is a motor 310. The motor 310 drives the slider 320 to move through the ball screw 330. The ball screw 330 has the advantages of high transmission efficiency, fast response speed and large driving force. It can quickly and accurately drive the blade 200 to open and close, so that the air intake grille can be adjusted in time according to the vehicle driving status, which effectively improves the vehicle's aerodynamic performance and fuel economy.

[0036] It is understood that in some other embodiments, the driving device may also be to move the slider 320 by a cylinder, or the motor 310 may drive the slider 320 to move by a transmission component such as a gear and rack, or the slider 320 may be moved by an electric push rod.

[0037] Reference Figure 2 and Figure 4The frame also includes two second limiting plates 130, which are located on both sides of the sliding direction of the blade 200. When the blade 200 abuts against one of the second limiting plates 130, the blade 200 closes the air inlet 111; when the blade 200 abuts against the other second limiting plate 130, the blade 200 opens the air inlet 111. When the blade 200 slides to its limit position, its end will directly contact the limiting plate, forming a physical barrier to prevent the blade 200 from exceeding the preset stroke due to inertia or excessive drive. When the blade 200 slides in the "closed" direction and finally abuts against one of the second limiting plates 130, all the blocking parts 210 of the blade 200 exactly completely cover the air inlet 111 of the base plate 110. The blocking effect of the limiting plate ensures that the blade 200 will not continue to slide, causing the blocking parts 210 to become misaligned. When the blade 200 slides in the "open" direction and comes into contact with another second limiting plate 130, all the blocking parts 210 of the blade 200 are just completely away from the air inlet 111 (the air inlet 111 is fully exposed, and the airflow can pass through to the maximum extent). The function of the limiting plate at this time is to prevent the blade 200 from sliding excessively and disengaging from the guide rail groove 121 of the frame.

[0038] The present invention also proposes a vehicle according to a second aspect embodiment, including a sliding active air intake grille according to the first aspect embodiment of the present invention, wherein the sliding active air intake grille is disposed at the front of the vehicle.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
