Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, specifically to an air intake device and a vehicle. Background Technology

[0002] As an important component of the vehicle's thermal management system, the active grille shutter plays a crucial role in controlling engine temperature by regulating the airflow into the engine compartment. It also optimizes the vehicle's aerodynamic performance, thereby affecting fuel economy, emissions levels, and high-speed stability.

[0003] Currently, most common active air intake grilles employ a motor-driven blade rotation scheme, controlling the effective ventilation area of ​​the air intake by adjusting the opening and closing angle of the blades. In some typical structures, the air intake grille has several blade groups, with multiple blades linked together by a single or a few motors via a linkage mechanism, simplifying the control logic and reducing manufacturing costs.

[0004] This type of structure can meet basic intake regulation needs under normal operating conditions, but under certain special conditions, such as high-speed airflow impact, low temperature icing, or high load heat dissipation requirements, its mechanical structure and driving capability are still insufficient. Utility Model Content

[0005] This application provides an air intake device and a vehicle to solve the problem of meeting the requirements of mechanical structure and driving capability for high-speed airflow impact, low-temperature icing, or high-load heat dissipation.

[0006] In a first aspect, this application provides an air intake device, comprising: The grille is provided with a pair of air inlets, the pair of air inlets being spaced apart along a first direction, and the area between the pair of air inlets on the grille is set as an installation area. An air intake assembly is provided in pairs, each pair of air intake assemblies corresponding to a pair of air intake holes. Each air intake assembly includes a drive member and a blade. The blade is located inside the air intake hole and is adapted to the air intake hole. The drive members of each pair of air intake assemblies are provided in the mounting area. The drive members are adapted to drive the blade to rotate in order to open or block the air intake hole.

[0007] Beneficial effects: By setting up a pair of intake components corresponding to independent air inlets, and centrally arranging the two drive units in the mounting area between the two air inlets, independent and precise control of the two intake channels is achieved. Specifically, each drive unit drives a large blade. Compared to a structure that drives multiple linked small blades, the load is significantly reduced, thus providing a stronger driving force and faster response speed for each blade. This ensures that under complex operating conditions such as high-load heat dissipation requirements or high-speed airflow impact, each air inlet can be opened or closed stably and reliably, improving the adjustment capability and reliability of the intake system.

[0008] In one optional embodiment, the intake assembly further includes: A rotating shaft includes a first end and a second end opposite to each other. The first end of the rotating shaft is connected to the driving member, and the second end of the rotating shaft is connected to the end of the blade away from the driving member along the first direction. The mounting component is connected to the rotating shaft, and the mounting component is connected to the blade by fasteners.

[0009] Beneficial effects: By using a single shaft to connect the drive unit and the blades, the power transmission path becomes more efficient. The single-shaft design avoids the structural complexity, transmission efficiency loss, and potential backlash issues inherent in traditional multi-link mechanisms. It allows for the lossless direct transmission of the large torque generated by the motor to the blades, enhancing the shaft's torsional strength and control over large blades. Simultaneously, the robust connection between the blades and the shaft, achieved through mounting components and fasteners, ensures the rigidity and stability of the overall structure, preventing blade deformation or vibration during movement and resulting in smoother and more precise motion.

[0010] In one optional embodiment, a limiting protrusion is provided on the circumferential surface of the rotating shaft. The limiting protrusion is provided with a first end face and a second end face opposite to each other along the circumferential direction of the rotating shaft. The mounting area is provided with a recess, and the rotating shaft is located in the recess. The recess extends along the axial direction of the rotating shaft, and the limiting protrusion extends out from the recess. When the blade is closed, the first end face abuts against one side of the recess. When the blade is open, the second end face abuts against the other opposite side of the recess.

[0011] Beneficial effects: By cooperating with the limiting protrusion on the circumference of the rotating shaft and the recess in the mounting area, mechanical limits are provided for the opening and closing positions of the blades. This defines the maximum opening angle and the fully closed position of the blades, effectively preventing over-opening, rebounding, or incomplete closing due to inertia or external airflow impact. The first and second end faces abut against the sides of the recess, ensuring the stability and positioning accuracy of the blades at their extreme positions, thus guaranteeing the expected sealing effect and air intake area under various driving conditions.

[0012] In one alternative implementation, it further includes: A buckle plate is connected to the mounting area. The mounting area has a first groove on the side facing the buckle plate, and the buckle plate has a second groove on the side facing the mounting area. A mounting cavity is formed between the first groove and the second groove. The driving component is located in the mounting cavity. The first end of the rotating shaft extends into the mounting cavity and is connected to the output end of the driving component.

[0013] Beneficial effects: The mounting plate, in conjunction with the installation area, forms a sealed installation chamber, completely enclosing and protecting the drive unit and its connection to the shaft. This design provides a highly sealed working environment for the drive unit, reducing the risk of corrosion, short circuits, or icing and jamming caused by external environmental factors, thus improving the durability and environmental adaptability of the drive unit.

[0014] In one alternative embodiment, the blade comprises: An outer panel and an inner panel are connected together. An insert plate is provided on the side of the outer panel facing the inner panel, and a slot is provided on the inner panel. The insert plate is inserted into the slot, and the side of the inner panel away from the outer panel is connected to the mounting component.

[0015] Beneficial effects: The insertion and engagement of the insert plate on the outer plate with the slot on the inner plate enables rapid, accurate positioning and reliable connection between the outer and inner plates. The split design of the blade simplifies the mold structure, reduces the manufacturing difficulty and cost of large curved blades, and allows the inner and outer plates to use different materials or processes. The insertion structure consisting of the insert plate and slot ensures the connection strength of the inner and outer plates under various loads, prevents separation due to vibration or airflow suction, and improves the overall structural integrity and service life of the blade.

[0016] In one alternative embodiment, of the outer plate and the inner plate, at least the outer plate is configured as an arcuate structure that protrudes away from the axis of rotation.

[0017] Beneficial effects: The blades are designed with an arc-shaped structure that bulges forward towards the vehicle. This arc surface can adapt to and effectively guide the incoming airflow, reducing the obstruction and turbulence of the airflow by the grille mechanism, thereby reducing the vehicle's air resistance.

[0018] In one alternative implementation, it further includes: An air intake shroud is connected to the side edge of the grille. The rotating shaft and the driving component are both located between the air intake shroud and the grille. The air intake shroud has an air intake channel, and the air intake hole communicates with the air intake channel.

[0019] Beneficial effects: The air intake shroud can guide the airflow collected by the grille into the engine compartment, reducing airflow separation and energy loss at the inlet and improving intake efficiency.

[0020] In one alternative embodiment, a sealing layer is provided between the grille and the air intake shroud.

[0021] Beneficial effects: The sealing layer between the grille and the air intake shroud improves the sealing of the entire intake system when the blades are closed, reduces air leakage from gaps, and ensures that cooling airflow can enter through the designed channels. This reduces air resistance and improves fuel economy when reduced air intake is required.

[0022] In one optional embodiment, the driving component is configured as a motor, the driving end of the driving component is provided with a groove, the first end of the rotating shaft is inserted into the groove, the inner wall of the groove is provided with a plurality of notches spaced apart along its circumference, and the circumferential surface of the first end of the rotating shaft is provided with a plurality of insertion protrusions spaced apart along its circumference, the notches being adapted to the insertion protrusions.

[0023] Beneficial effects: The power transmission between the motor and the shaft is achieved through the spline-type engagement between the recessed groove at the drive end of the drive component and the protruding protrusion at the first end of the shaft. This increases the contact area and improves the torque transmission capacity.

[0024] Secondly, this application also provides a vehicle including an air intake device.

[0025] Since the vehicle includes an air intake system, which has the same effect as an air intake system, it will not be elaborated on here. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The following is combined with Figures 1 to 16 This describes an embodiment of the present application.

[0031] According to an embodiment of this application, an air intake device is provided, including a grille 1 and an air intake assembly 2. The grille 1 is provided with a pair of air intake holes 101, which are spaced apart along a first direction X. The area between the pair of air intake holes 101 on the grille 1 is set as an installation area 102. A pair of air intake assemblies 2 are provided, each corresponding to a pair of air intake holes 101. Each air intake assembly 2 includes a drive member 201 and a blade 202. The blade 202 is located inside the air intake hole 101 and is adapted to fit the air intake hole 101. The drive members 201 of the pair of air intake assemblies 2 are both disposed in the installation area 102. The drive members 201 are adapted to drive the blade 202 to rotate, thereby opening or blocking the air intake hole 101.

[0032] It should be noted that the blade 202 is designed as a large-sized integral structure. When the grille 1 is closed, one blade 202 can completely seal one air intake 101. Each blade 202 is driven individually by a drive unit 201, so that all the torque of the drive unit 201 is applied to the blade 202. At the same time, the torque of the drive unit 201 used is greater than that of commonly used drive units 201 in the field.

[0033] Understandably, to maximize the air intake area of ​​the air intake 101, the two air intakes 101 are spaced apart along the first direction X, where X is the vehicle width direction. The mounting area 102 and the grille 1 are an integral structure, and the grille 1 is made of high-strength material.

[0034] Optionally, the grille 1 is provided with mounting holes for fixed connection to the front structure of the vehicle by screws, specifically to the bumper skin.

[0035] In this embodiment, by setting a pair of intake components 2 corresponding to independent air inlets 101 respectively, and centrally arranging two drive units 201 in the mounting area 102 between the two air inlets 101, independent and precise control of the two intake channels is achieved. Specifically, each drive unit 201 drives a large blade 202. Compared with the structure that drives multiple linked small blades 202, the load is significantly reduced, thereby providing a stronger driving force and a faster response speed for each blade 202. This ensures that under complex working conditions such as high-load heat dissipation requirements or high-speed airflow impact, each air inlet 101 can be opened or closed stably and reliably, improving the adjustment capability and reliability of the intake system.

[0036] In one embodiment, the intake assembly 2 further includes a shaft 203 and a mounting member 204. The shaft 203 includes a first end 2031 and a second end 2032 opposite to each other. The first end 2031 of the shaft 203 is connected to the drive member 201, and the second end 2032 of the shaft 203 is connected to the end of the blade 202 away from the drive member 201 along a first direction X. The mounting member 204 is connected to the shaft 203, and the mounting member 204 is connected to the blade 202 by fasteners.

[0037] It should be noted that the intake assembly 2 adopts a single rotating shaft 203, which is made of aluminum alloy. The rotating shaft 203 can be die-cast and knurled to reduce its weight, enabling it to withstand a sufficiently large driving torque to drive the large blades 202 to move stably and reliably under various complex working conditions.

[0038] Understandably, the mounting component 204 and the rotating shaft 203 can be constructed as an integral structure, or they can be connected by fasteners, which are bolts.

[0039] In this embodiment, a single rotating shaft 203 is used to connect the drive component 201 and the blade 202, making the power transmission path more efficient. The single rotating shaft 203 avoids the problems of structural complexity, transmission efficiency loss, and potential backlash present in traditional multi-link mechanisms. It can directly transmit the large torque generated by the motor to the blade 202 without loss, enhancing the torsional strength of the rotating shaft 203 and the ability to control the large-sized blade 202. Simultaneously, the mounting component 204 and fasteners ensure a secure connection between the blade 202 and the rotating shaft 203, guaranteeing the rigidity and stability of the overall structure. This prevents the blade 202 from deforming or vibrating during movement, resulting in smoother and more precise motion.

[0040] In one embodiment, a limiting protrusion 2033 is provided on the circumferential surface of the rotating shaft 203. The limiting protrusion 2033 is provided with a first end 2031 surface and a second end 2032 surface respectively along the circumferential direction of the rotating shaft 203. The mounting area 102 is provided with a recess 103. The rotating shaft 203 is located in the recess 103. The recess 103 extends along the axial direction of the rotating shaft 203. The limiting protrusion 2033 extends out from the recess 103. When the blade 202 is closed, the first end 2031 surface abuts against one side of the recess 103. When the blade 202 is open, the second end 2032 surface abuts against the other opposite side of the recess 103.

[0041] It should be noted that the limiting protrusion 2033 and the rotating shaft 203 can be constructed as an integral structure, which can improve the structural strength of the transmission components.

[0042] Optionally, the limiting protrusion 2033 can be configured as a fan-shaped structure, with the center of the fan-shaped structure coinciding with the axis of the rotating shaft 203. The two opposing first end 2031 surfaces and second end 2032 surfaces of the limiting protrusion 2033 are the two side surfaces of the limiting protrusion 2033 of the fan-shaped structure that are parallel to the axis of the rotating shaft 203.

[0043] In this embodiment, the limiting protrusion 2033 on the circumference of the rotating shaft 203 cooperates with the recess 103 in the mounting area 102 to provide mechanical limits for the opening and closing positions of the blade 202. This defines the maximum opening angle and fully closed position of the blade 202, effectively preventing the blade 202 from over-opening, rebounding, or not closing properly due to inertia or external airflow impact. The first end 2031 and the second end 2032 abut against the two sides of the recess 103, ensuring the stability and positioning accuracy of the blade 202 at its extreme positions, thereby guaranteeing the expected sealing effect and air intake area under various driving conditions.

[0044] In one embodiment, a buckle plate 3 is also included, which is connected to the mounting area 102. The mounting area 102 has a first groove 104 on the side facing the buckle plate 3, and the buckle plate 3 has a second groove 301 on the side facing the mounting area 102. An mounting cavity is formed between the first groove 104 and the second groove 301. The drive member 201 is located in the mounting cavity, and the first end 2031 of the rotating shaft 203 extends into the mounting cavity and is connected to the output end of the drive member 201.

[0045] It should be noted that the mounting area 102 of the buckle plate 3 and the grille 1 are connected by bolts, and the buckle plate 3 and the second groove 301 are constructed as an integral structure. The second groove 301 and the grille 1 are constructed as an integral structure.

[0046] Optionally, a sealing groove 105 is provided on the inner wall of the installation chamber, and a sealing element can be installed in the sealing groove 105.

[0047] In this embodiment, the buckle plate 3 cooperates with the mounting area 102 to form a closed mounting chamber, completely enclosing and protecting the drive component 201 and its connection with the rotating shaft 203. This design provides a highly sealed working environment for the drive unit, reducing the possibility of corrosion, short circuits, or icing and jamming caused by the external environment to the drive component 201, and improving the durability and environmental adaptability of the drive component 201.

[0048] In one embodiment, the blade 202 includes an outer plate 2021 and an inner plate 2022 connected together. An insert plate 2023 is provided on the side of the outer plate 2021 facing the inner plate 2022, and a slot 2024 is provided on the inner plate 2022. The insert plate 2023 is inserted into the slot 2024, and the side of the inner plate 2022 away from the outer plate 2021 is connected to the mounting member 204.

[0049] It should be noted that the outer panel 2021 and the inner panel 2022 are connected by bolts, the inner panel 2022 is connected to the mounting part 204 by bolts, and the insert plate 2023 and the outer panel 2021 are constructed as an integral structure.

[0050] In this embodiment, the insertion plate 2023 on the outer plate 2021 and the slot 2024 on the inner plate 2022 are engaged to achieve rapid, accurate positioning and reliable connection between the outer plate 2021 and the inner plate 2022. The split design of the blade 202 simplifies the mold structure, reduces the manufacturing difficulty and cost of the large curved blade 202, and allows the inner and outer plates 2021 to use different materials or processes. The insertion structure formed by the insertion plate 2023 and the slot 2024 ensures the connection strength of the inner and outer plates 2021 under various loads, prevents separation due to vibration or airflow suction, and improves the overall structural integrity and service life of the blade 202.

[0051] In one embodiment, of the outer plate 2021 and the inner plate 2022, at least the outer plate 2021 is configured as an arcuate structure that protrudes in a direction away from the pivot 203.

[0052] It should be noted that when the blade 202 is in the open state, because the blade 202 adopts an arc-shaped structure design and the arc-shaped protrusion faces the front of the vehicle, it can effectively guide the airflow, reduce the air resistance during vehicle driving, and lower the vehicle's drag coefficient. The optimization of intake performance and drag performance will improve the vehicle's fuel economy and driving stability.

[0053] In this embodiment, the blade 202 is designed as an arc-shaped structure that protrudes towards the front of the vehicle. This arc-shaped surface can adapt to and effectively guide the incoming airflow, reducing the obstruction and turbulence of the airflow by the grille 1 mechanism, thereby reducing the vehicle's air resistance.

[0054] In one embodiment, an air intake shroud 4 is also included, which is connected to the side edge of the grille 1. The rotating shaft 203 and the drive component 201 are both located between the air intake shroud 4 and the grille 1. The air intake shroud 4 has an air intake channel, and the air intake hole 101 communicates with the air intake channel.

[0055] In this embodiment, the air intake shroud 4 can guide the airflow collected by the grille 1 into the engine compartment, reducing airflow separation and energy loss at the inlet and improving intake efficiency.

[0056] In one embodiment, a sealing layer is provided between the grille 1 and the air intake shroud 4.

[0057] It should be noted that soft rubber overlap is used as a seal between the grille 1 and the air intake hood 4.

[0058] Alternatively, compressed foam overlap can be used as a seal between the grille 1 and the air intake shroud 4.

[0059] In this embodiment, a sealing layer is provided between the grille 1 and the air intake shroud 4, which improves the sealing performance of the entire air intake system when the blades 202 are closed, reduces air leakage from the gaps, and ensures that the cooling airflow can enter through the designed channels. This reduces air resistance and improves fuel economy when air intake needs to be reduced.

[0060] In one embodiment, the drive member 201 is configured as a motor, the drive end of the drive member 201 is provided with a groove, the first end 2031 of the rotating shaft 203 is inserted into the groove, the inner wall of the groove is provided with a plurality of notches at intervals along its circumference, and the circumferential surface of the first end 2031 of the rotating shaft 203 is provided with a plurality of insertion protrusions 2034 at intervals along its circumference, and the notches are adapted to the insertion protrusions 2034.

[0061] Understandably, the setup of the protrusion 2034 and the notch is a spline connection.

[0062] In this embodiment, power transmission between the motor and the rotating shaft 203 is achieved through a splined engagement between the groove at the driving end of the driving component 201 and the splined engagement between the protrusion 2034 at the first end 2031 of the rotating shaft 203. This increases the contact area and improves the torque transmission capability.

[0063] According to an embodiment of this application, another aspect provides a vehicle including an air intake device.

[0064] Since the vehicle includes an air intake system, which has the same effect as an air intake system, it will not be elaborated on here.
