Description

Technical Field

[0001] The present invention relates to the field of automobiles, and in particular to a blade adjusting device and an automobile. Background Art

[0002] Active air intake grilles can adjust the opening and closing angles of the grille blades based on the vehicle's actual driving conditions (engine oil and water temperatures, engine speed, and vehicle speed), regulating the amount of air entering the engine compartment, reducing internal circulation resistance and fuel consumption. They also accelerate engine warm-up and reduce emissions. With increasing demands for energy conservation and emission reduction, active air intake grilles are gaining popularity among more companies and customers.

[0003] Considering factors such as air intake volume and styling, the air intake area of ​​a car is typically large, requiring multiple grille vanes. Existing active air intake grilles can achieve motor-driven rotation of the grille vane assembly, but they cannot individually control the opening and closing of individual grille vanes, nor can they control the opening and closing of multiple grille vanes in groups. Summary of the Invention

[0004] The present invention aims to solve the problem in prior art active air intake grilles that the opening and closing of grille blades cannot be controlled individually or in groups. Therefore, the present invention provides a blade adjustment device and a vehicle that have the advantage of being able to control the opening and closing of blades individually or in groups.

[0005] To solve the above problems, an embodiment of the present invention provides a blade adjustment device, comprising:

[0006] A transmission belt, wherein the transmission belt is provided with a toothed structure;

[0007] Multiple blades and multiple operating levers, the multiple blades are spaced apart along the length of the transmission belt, the multiple operating levers are connected to the multiple blades in a one-to-one correspondence to drive the corresponding blades to rotate, each operating lever is provided with a transmission wheel with teeth, and the teeth of each transmission wheel are used to match the tooth structure on the transmission belt;

[0008] A driving mechanism is connected to the transmission belt to drive the transmission belt to move in a first direction or a second direction, so that the toothed structure of the transmission belt engages with the teeth of at least one transmission wheel and links the corresponding operating lever to rotate, wherein the first direction is opposite to the second direction.

[0009] With the above technical solution, a toothed transmission wheel is provided on the operating lever of each blade, and a toothed structure is provided on the transmission belt, wherein the toothed structure matches the teeth of the transmission wheel. When the toothed structure engages with the teeth of a transmission gear in the first direction or the second direction under the drive mechanism, the opening or closing of a single blade can be controlled individually. When the toothed structure sequentially engages with the teeth of multiple transmission wheels, the opening or closing of multiple blades can be controlled in groups. Therefore, the blade adjustment device has the advantage of being able to control the opening and closing of blades individually or in groups.

[0010] Furthermore, another embodiment of the present invention provides a blade adjustment device, wherein the transmission belt is an annular transmission belt, the driving mechanism includes a motor and a driving wheel, and driving wheels are respectively provided at both ends of the annular transmission belt. The driving wheels are connected to the inner surface of the annular transmission belt, and the motor drives the transmission belt to move through the driving wheels.

[0011] By adopting the above technical solution, by arranging driving wheels at both ends of the circular transmission belt, the motor can conveniently drive the circular transmission belt to move in the first direction or the second direction through the driving wheels, so that the tooth structure on the circular transmission belt engages with the teeth of the transmission wheel, which is flexible.

[0012] Furthermore, another embodiment of the present invention provides a blade adjustment device, wherein a resistance structure is also provided on the transmission belt. In the first direction, the resistance structure is located upstream of the tooth structure. When the transmission belt moves along the first direction, the resistance structure enables at least one transmission wheel engaged with the tooth structure to maintain the rotation angle after engagement.

[0013] By adopting the above technical solution, a resistance structure is provided so that the resistance structure supports at least one transmission wheel engaged with the tooth structure, thereby preventing at least one blade engaged with the tooth structure from rotating freely due to unstable center of gravity.

[0014] Furthermore, another embodiment of the present invention provides a blade adjustment device, wherein the resistance structure is a protrusion protruding outward on the outer surface of the transmission belt, and the protrusion extends along the length direction of the transmission belt.

[0015] By adopting the above technical solution, by setting a protrusion extending along the length direction of the transmission belt, after the teeth of multiple transmission wheels are engaged with the tooth structure of the transmission belt, the protrusion can enable the multiple transmission wheels to maintain the rotation angle after engagement, that is, to keep the multiple blades in the open state.

[0016] Furthermore, another embodiment of the present invention provides a blade adjustment device, which further includes a frame, a plurality of operating rods passing through the plurality of blades one by one, and two ends of each operating rod are rotatably connected to the frame.

[0017] Furthermore, another embodiment of the present invention provides a blade adjustment device, wherein the transmission wheel is sleeved on the operating rod located between the frame and the blade.

[0018] Furthermore, another embodiment of the present invention provides a blade adjustment device, wherein the rotation angle of the blade is 0° to 90°.

[0019] Yet another embodiment of the present invention provides a car, comprising a car body, wherein the blade adjusting device as described above is provided in the car body.

[0020] Furthermore, another embodiment of the present invention provides a car, which is also equipped with a temperature sensor, a speed sensor and a controller in the car body. The temperature sensor and the speed sensor are both communicatively connected to the controller to transmit the engine water temperature signal detected by the temperature sensor and the car speed signal detected by the speed sensor to the controller. The controller controls the driving mechanism to adjust the movement direction of the transmission belt according to the engine water temperature signal and the car speed signal.

[0021] The above technical solution is adopted by arranging a temperature sensor, a speed sensor, and a controller in the vehicle body. During the actual driving process of the vehicle, when the controller receives a signal from the temperature sensor and the speed sensor indicating that the intake air volume needs to be increased, the controller controls the drive mechanism to drive the transmission belt in a first direction. When the toothed structure of the transmission belt meshes with the teeth of at least one transmission wheel, the linkage joystick rotates, thereby opening the blades. When the controller receives a signal from the temperature sensor and the speed sensor indicating that the intake air volume needs to be reduced, the controller controls the drive mechanism to drive the transmission belt in a second direction. The toothed structure of the transmission belt meshes with the teeth of at least one transmission wheel to close the blades. Therefore, the above technical solution enables the controller to accurately and flexibly control the opening and closing of the blades individually or in groups according to the actual driving process of the vehicle, thereby accurately and flexibly controlling the intake air volume of the engine compartment, reducing the engine's drag coefficient, improving fuel economy, and achieving the dual benefits of fuel consumption and emissions.

[0038] Example 1:

[0039] See Figure 1 , Figure 1 A schematic structural diagram of a blade adjustment device provided in an embodiment of the present invention.

[0040] The blade adjustment device 10 provided in an embodiment of the present invention includes a transmission belt 100, a plurality of blades 210, a plurality of operating levers 220, and a driving mechanism 300. The blade adjustment device 10 is used to flexibly adjust the air intake volume of the engine compartment.

[0041] The transmission belt 100 is provided with a toothed structure 110. In this embodiment, the transmission belt 100 and the toothed structure 110 can be made of rubber.

[0042] The plurality of blades 210 are arranged at intervals along the length direction L3 of the transmission belt 100. A plurality of operating levers 220 are connected to the plurality of blades 210 in a one-to-one correspondence to drive the corresponding blade 210 to rotate. Each operating lever 220 is provided with a transmission wheel 221 having teeth 2210. The teeth 2210 of each transmission wheel 221 are configured to mate with the toothed structure 110 on the transmission belt 100. In this embodiment, the transmission wheel 221 and its teeth 2210 may be made of rubber.

[0043] The driving mechanism 300 is in transmission connection with the transmission belt 100 to drive the transmission belt 100 to move in the first direction L1 or the second direction L2, so that the toothed structure 110 of the transmission belt 100 engages with the teeth 2210 of at least one transmission wheel 221, and the corresponding operating lever 220 is rotated in conjunction with the toothed structure 110 of the transmission belt 100. The first direction L1 is opposite to the second direction L2. In this embodiment, Figure 1 As shown, the first direction L1 is counterclockwise and the second direction L2 is clockwise. Those skilled in the art will appreciate that, in alternative embodiments, the first direction L1 may also be clockwise and the second direction L2 may also be counterclockwise.

[0044] In this embodiment, a transmission wheel 221 with teeth 2210 is provided on the operating lever 220 of each blade 210, and a toothed structure 110 is provided on the transmission belt 100, and the toothed structure 110 matches the teeth 2210 of the transmission wheel 221. When the toothed structure 110 is driven by the drive mechanism 300, the opening or closing of a single blade 210 can be controlled individually when it meshes with the teeth 2210 of a transmission gear in the first direction L1 or the second direction L2. When the toothed structure 110 sequentially meshes with the teeth 2210 of multiple transmission wheels 221, the opening or closing of multiple blades 210 can be controlled in groups. Therefore, the blade adjustment device 10 has the advantage of being able to control the opening and closing of the blades 210 individually or in groups.

[0045] Furthermore, the transmission belt 100 is an endless transmission belt, and the driving mechanism 300 includes a motor (not shown) and a driving wheel 310. The driving wheels 310 are respectively provided at both ends of the endless transmission belt. The driving wheels 310 are connected to the inner surface of the endless transmission belt, and the motor drives the transmission belt 100 to move through the driving wheels 310. In this embodiment, the output shaft 320 of the motor is in transmission connection with one of the driving wheels 310. The movement direction and movement distance of the endless transmission belt are controlled by the motor through the output shaft 320.

[0046] In this embodiment, by arranging driving wheels 310 at both ends of the annular transmission belt, the motor can conveniently drive the annular transmission belt to move along the first direction L1 or the second direction L2 through the driving wheel 310, so that the toothed structure 110 on the annular transmission belt engages with the teeth 2210 of the transmission wheel 221, which is flexible.

[0047] Furthermore, in this embodiment, in the first direction L1, one end of the transmission belt 100 extends to the position of the first transmission pulley 221, and the other end of the transmission belt 100 extends to the position of the last transmission pulley 221. When the rotation angle of the blades 210 needs to be changed, that is, when the blades 210 are opened or closed, the transmission belt 100 moves in a circular motion within its own length, so that the toothed structure 110 engages with the teeth 2210 of the transmission pulley 221. Therefore, there is no need to occupy space outside the length of the transmission belt 100 itself, and there is no need to consider the problem of the transmission belt 100 interfering with external structures (such as a frame) when controlling the opening and closing of multiple blades 210.

[0048] Furthermore, the transmission belt 100 is provided with a resistance structure 120. In the first direction L1, the resistance structure 120 is located upstream of the toothed structure 110. When the transmission belt 100 moves in the first direction L1, the resistance structure 120 ensures that the at least one transmission wheel 221 engaged with the toothed structure 110 maintains its rotational angle. In this embodiment, the rotation angle of the blade 210 is between 0° and 90°. When the rotation angle of the blade 210 is 0°, the blade 210 is in a closed state, and when the rotation angle of the blade 210 is 90°, the blade 210 is in an open state.

[0049] In this embodiment, the resistance structure 120 is provided to support the at least one transmission wheel 221 engaged with the tooth structure 110, thereby preventing the at least one blade 210 engaged with the tooth structure 110 from rotating freely due to unstable center of gravity.

[0050] Specifically, the resistance structure 120 is a protrusion protruding outwardly from the outer surface of the transmission belt 100, extending along the length direction L3 of the transmission belt 100. The protrusion extends for a length less than the overall length of the transmission belt 100. In this embodiment, the protrusion extends for a length less than and approximately equal to half the overall length of the transmission belt 100. Furthermore, the highest surface of the protrusion is flush or nearly flush with the highest surface of the toothed structure 110 of the transmission belt 100.

[0051] like Figure 1As shown, when the drive mechanism 300 drives the transmission belt 100 to move in the first direction L1, the teeth 2210 of the transmission wheel 221 engage with the toothed structure 110 of the transmission belt 100 and then abut against the protrusion. When the drive mechanism 300 drives the transmission belt 100 to continue moving in the first direction L1, the protrusion pushes up the teeth 2210, at which point the rotation angle of the blade 210 is 90°. Thereafter, as the transmission belt 100 continues to move in the first direction L1, the protrusion pushes up against the teeth 2210 at the 90° rotation angle, preventing the blade 210 from rotating freely due to an unstable center of gravity. When the drive mechanism 300 drives the transmission belt 100 to move in the first direction L1, causing the protrusion to disengage from the blade 210, the rotation angle of the blade 210 that has disengaged from the protrusion becomes 0°.

[0052] In this embodiment, a protrusion is provided to extend along the length direction L3 of the transmission belt 100 so that after the teeth 2210 of multiple transmission wheels 221 are engaged with the tooth structure 110 of the transmission belt 100, the protrusion can enable the multiple transmission wheels 221 to maintain the rotation angle after engagement, that is, the multiple blades 210 remain in the open state.

[0053] Furthermore, the blade adjustment device 10 further includes a frame (not shown), a plurality of joysticks 220 extending through the plurality of blades 210, each joystick 220 having two ends rotatably connected to the frame, and a transmission wheel 221 disposed on the joystick 220 between the frame and the blades 210. In this embodiment, one end of each joystick 220 is rotatably connected to one side of the frame, and the other end of each joystick 220 is rotatably connected to the other side of the frame, with one side of the frame facing the other side of the frame. Furthermore, in this embodiment, the axial direction of each joystick 220 is parallel to, but does not overlap, the centerline of each blade 210 in the longitudinal direction.

[0054] Example 2:

[0055] A car provided in another embodiment of the present invention includes a car body (not shown in the figures), in which the blade adjustment device 10 in Example 1 is provided.

[0056] A temperature sensor, a speed sensor and a controller (not shown in the figure) are also provided in the vehicle body. The temperature sensor and the speed sensor are both connected to the controller for communication so as to transmit the engine water temperature signal detected by the temperature sensor or the vehicle speed signal detected by the speed sensor to the controller. The controller controls the driving mechanism 300 to adjust the movement direction of the transmission belt 100 according to the engine water temperature signal or the vehicle speed signal.

[0057] In this embodiment, taking the case where all blades 210 are closed to open as an example, at the beginning, all blades 210 are in a closed state by default, that is, the rotation angle of all blades 210 is 0°. During the actual driving of the car, when the controller receives a signal from the temperature sensor and the speed sensor requiring an increase in the intake volume, the drive mechanism 300 is controlled to drive the transmission belt 100 to move in the first direction L1. When the tooth structure 110 of the transmission belt 100 engages with the teeth 2210 of at least one transmission wheel 221, the linkage operating lever 220 is rotated to realize the opening of the blades 210, that is, the rotation angle of the blades 210 is 90°.

[0058] When the controller receives signals from the temperature sensor and the speed sensor indicating a need to reduce the intake air volume, if only some of the blades 210 are open, the controller can control the drive mechanism 300 to drive the transmission belt 100 in the second direction L2. The toothed structure 110 of the transmission belt 100 engages with the teeth 2210 of at least one transmission wheel 221 to close the blades 210, i.e., the rotation angle of the blades 210 becomes 0°. The closed blades 210 no longer need the protrusion to support them. If all blades 210 are open, the controller can control the drive mechanism 300 to drive the transmission belt 100 to continue moving in the first direction L1, so that the protrusion passes the blades 210 to be closed. The rotation angle of the blades 210 without the protrusion's support becomes 0°. When the toothed structure 110 moves from the upper side 311 of the drive wheel 310 to the lower side 312 of the drive wheel 310, and the protrusion passes the last blade 210 in the first direction L1, the rotation angle of all blades 210 becomes 0°.

[0059] Therefore, this embodiment provides a temperature sensor, a speed sensor and a controller in the vehicle body, so that the controller can accurately and flexibly automatically control the intelligent opening and closing of the blades 210 individually or in groups according to the specific air intake requirements during the actual driving process of the car, thereby accurately and flexibly and automatically controlling the air intake volume of the engine compartment, reducing the engine's drag coefficient, improving fuel economy, and achieving dual benefits in fuel consumption and emissions.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
