[0002] In existing technology, the blades in the air intake grille assembly can be rotated by a motor, thereby adjusting the blade opening. However, simply adjusting the blade opening is insufficient to adapt the blades to various vehicle operating conditions. Summary of the Invention

[0003] This invention aims to solve the problem in existing technologies where air intake grilles can only adjust the opening of the grille blades, failing to adapt the blades to various operating conditions. Therefore, the purpose of this invention is to propose an air intake grille assembly to address the problems existing in the prior art.

This allows the blades to not only adjust their opening degree but also their position, enabling them to adjust their state and position under different operating conditions and thus adapt to different working conditions.

[0006] In some embodiments, the blades extend along the width direction of the vehicle, and multiple blades are provided, with the multiple blades spaced apart along the height direction of the vehicle.

[0018] This invention also proposes an air intake grille control method, comprising: controlling the movement of blades relative to the grille body according to preset conditions.

[0019] In some embodiments, controlling the movement of the blades relative to the grid body according to preset conditions includes: Based on the collision signal from the air intake grille, the blades are controlled to move relative to the grille body.

[0020] In some embodiments, controlling the movement of the blades relative to the grille body based on a collision signal from the air intake grille includes: When a collision signal is received, the control drive unit drives the blades to move in the direction of the vehicle's rear.

[0021] In some embodiments, controlling the movement of the blades relative to the grid body according to preset conditions further includes: When the blades are in the open state, the blades are controlled to move relative to the grid body by comparing the temperature value detected by the temperature sensor of the power unit with the first preset temperature threshold.

[0023] In some embodiments, controlling the movement of the blades relative to the grid body according to preset conditions further includes: When the blades are in the open state, the blades are controlled to move relative to the grid body by comparing the temperature value detected by the crew cabin temperature sensor with the second preset temperature threshold.

[0029] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] An air intake grille assembly according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0031] like Figures 1-2 As shown, according to some embodiments of the present invention, blade 1 is connected to the air intake grille body, and blade 1 is also connected to a drive device 3. When preset conditions are met, the drive device 3 controls blade 1 to move relative to the grille body. In this embodiment, blade 1 extends along the width direction of vehicle 4, and multiple blades 1 are provided, with the multiple blades 1 spaced apart along the height direction of vehicle 4. At least one end of blade 1 is connected to the drive device 3, and at least one end of blade 1 is connected to the grille body.

[0032] Specifically, one end of the blade 1 is provided with a protrusion 13, and the protrusions 13 are provided at both ends of the blade 1. The extending direction of the protrusions 13 is the same as the extending direction of the blade 1. Correspondingly, two mounting parts 21 are provided on the grille body corresponding to the protrusions 13. The protrusions 13 can be mounted to the mounting parts 21 to connect the blade 1 and the grille body. The mounting parts 21 are configured such that when the blade 1 moves relative to the grille body under the drive of the drive device 3, the protrusions 13 move within the mounting parts 21. Figure 2 As shown in this embodiment, the mounting part 21 is configured with a cross-shaped mounting hole structure. This structure allows the protrusion 13 to move vertically or horizontally within the cross-shaped mounting hole, and the distance the protrusion 13 moves matches the size of the cross-shaped mounting hole. At least one end of the blade 1 is connected to the driving device 3. When driving the blade 1, the driving device 3 also provides support to the blade 1, enabling it to maintain stability without the support of the grille body. The driving device 3 is located at either end of the blade 1.

[0033] In some embodiments, the structure of the mounting portion 21 can be circular or rectangular, and the specific shape is not limited, as long as it allows the protrusion 13 to move within the mounting structure. In some embodiments, the blade 1 has a protrusion 13 at only one end, and the grille body has a mounting structure relative to the protrusion 13 of the blade 1. The grille body may not have a mounting structure, in which case the blade 1 is only supported by the drive device 3, which can drive the blade 1 to move in any direction. Depending on the movement requirements of the blade 1, the drive device 3 can be located at both ends of the blade 1, allowing the blade 1 to move more stably.

[0034] In some embodiments, a support structure is further provided between the plurality of blades 1, which can support the blades 1 to maintain stability. The arrangement of the support structure is not limited, as long as it does not restrict the movement of the blades 1 under the drive of the drive device 3.

[0035] In some embodiments, the blade 1 can extend vertically along the vehicle 4, and multiple blades 1 can be arranged horizontally along the vehicle 4.

[0036] In this embodiment of the application, a vehicle 4 is also proposed. The vehicle 4 includes a grille assembly and a collision sensor 41. The collision sensor 41 is used to detect whether the air intake grille assembly collides with an external object or person. When a collision occurs, the collision sensor 41 transmits a collision signal to a controller, which then controls the drive device 3 to move the blades 1 relative to the grille body.

[0037] In some embodiments, multiple collision sensors 41 may be provided as needed, and when any one of the collision sensors 41 detects a collision, it will transmit the collision signal to the controller.

[0038] In this embodiment, the collision sensor 41 is a pedestrian protection sensor. When a pedestrian collides with the grille assembly, the pedestrian protection sensor sends the detected collision signal to the controller. After receiving the signal, the controller sends a control command to the drive unit 3, which then drives the blade 1 to move away from the pedestrian. In this embodiment, the drive unit 3 drives the blade 1 to move behind the vehicle 4, so that the blade 1 is away from the pedestrian, preventing the pedestrian from suffering more serious injury.

[0039] In this embodiment, the vehicle 4 further includes a heat dissipation device 44 and a condensation device 45, which are arranged along the height direction of the vehicle 4. Both the heat dissipation device 44 and the condensation device 45 have blades 1 arranged on one side of the front of the vehicle 4.

[0040] In this embodiment, the vehicle 4 also includes a power unit temperature sensor 42 and a passenger compartment temperature sensor 43. The power unit temperature sensor 42 can detect the temperature of the power unit, and the passenger compartment temperature sensor 43 can detect the temperature of the passenger compartment. Specifically, the power unit temperature sensor 42 is configured as a motor temperature sensor.

[0041] The present invention also provides a method for controlling an air intake grille. Specifically, as shown in the example... Figures 4-5 As shown, blade 1 has two states: blade 1 open and blade 1 closed. The initial position of blade 1 is set as position X1, and the final position of blade 1 after moving behind vehicle 4 is set as position X2. When all blades 1 are in the open or closed state, the controller controls blade 1 to move behind vehicle 4, that is, blade 1 moves from position X1 to position X2. When multiple blades 1 are partially open or partially closed, the controller still controls blade 1 to move behind vehicle 4, that is, blade 1 moves from position X1 to position X2.

[0042] In some embodiments, the direction of movement of blade 1 can be set to other directions away from pedestrians.

[0043] In some embodiments, the collision sensor 41 can also be configured as other types of sensors. The type of sensor is selected according to the requirements, as long as it can detect the collision signal and send the collision signal to the controller so that the controller can control the blade 1 to move.

[0044] like Figure 8 As shown, vehicle 4 is also equipped with a cooling device 44 and a condensing device 45, as well as a power unit temperature sensor 42 and a passenger compartment temperature sensor 43. Specifically, the cooling device 44 and the condensing device 45 of vehicle 4 are arranged at intervals along the vertical direction of vehicle 4. The cooling device 44 is a radiator, and the condensing device 45 is a condenser. The condenser is located above the radiator. The condenser adjusts its operating state according to the temperature detected by the passenger compartment temperature sensor 43 to adjust the temperature of the passenger compartment. The radiator adjusts its operating state according to the temperature detected by the motor temperature sensor to adjust the temperature of the power unit. The condenser and radiator are provided with two sets of blades 1 along one side of the front of the vehicle 4. Each set of blades 1 has three blades 1. For each set of blades 1, the three blades 1 extend along the width direction of the vehicle 4 and are spaced apart along the height direction of the vehicle 4. The uppermost blade 1 of the three blades 1 is the second blade 12, the lowermost blade 1 of the three blades 1 is the first blade 11, and the middle blade 1 of the three blades 1 performs the functions of the first blade 11 and the second blade 12. The first blade 11 is located on one side of the radiator along the front direction of the vehicle, and the second blade 12 is located on one side of the condenser along the front direction of the vehicle. In the embodiment of this application, as... Figure 6As shown, the motor temperature is set to T1, and the first preset temperature threshold is T3. When T1 > T3, the motor needs to be cooled down, which requires the radiator to improve its cooling efficiency. At this time, the radiator needs a larger air intake. Therefore, the position of the first blade 11 in front of the radiator needs to be adjusted to increase the distance between the bottommost blade 11 and the middle blade 1. That is, the position of the bottommost blade 11 moves from its original position (third position Z1) along one side under the vehicle 4 until it reaches the fourth position Z3. Moving the first blade 11 from the third position Z1 to the fourth position Z3 increases the air intake area of ​​the grille in front of the radiator, thereby increasing the air intake volume of the grille.

[0045] In this embodiment, the passenger compartment temperature is set to T2, and the second preset temperature threshold is T4. When T2 > T4, the passenger compartment needs to be cooled, which requires the condenser to improve its cooling efficiency. At this time, the condenser needs a larger air intake. Therefore, the position of the second blade 12 in front of the condenser needs to be adjusted to increase the distance between the uppermost second blade 12 and the middle blade 1. That is, the position of the uppermost second blade 12 moves from its original position (fifth position Z2) along one side below the vehicle 4 until it reaches the sixth position Z4. Moving the second blade 12 from the fifth position Z2 to the sixth position Z4 increases the air intake area of ​​the grille in front of the condenser, thereby increasing the air intake volume of the air intake grille.

[0046] like Figure 6 As shown in this embodiment, the radiator and condenser do not always need to increase their air intake simultaneously. When the radiator needs to increase its air intake, the position of the first blade 11 is adjusted from the third position Z1 to the fourth position Z3. When the condenser needs to increase its air intake, the position of the second blade 12 is adjusted from the fifth position Z2 to the sixth position Z4.

[0047] In this embodiment, the positions of the two sets of blades 1 arranged along the width of the vehicle 4 are adjusted according to the air intake requirements of the radiator and condenser. The adjustment method is the same as the method described above, and will not be repeated here.

[0048] In some other embodiments, multiple blades 1 may be provided, and the direction and distance of movement of the blade 1 may be determined according to the needs of pedestrian protection and heat sink, and are not limited here.

[0049] This invention connects the blade 1 and the driving device 3, enabling the driving device 3 to drive the blade 1 to move relative to the grille body, thus solving the problem in the prior art that the blade 1 cannot move relative to the grille body, thereby expanding the application scenarios of the air intake grille.
