Facing various scenarios and needs, intelligent vehicle services are becoming an increasingly important highlight and selling point for automobiles. The front grille (usually called the front bumper) is a key component located at the very front of the car. It not only has a significant impact on the overall styling of the vehicle and the consumer's initial impression, but also bears the important responsibility of protecting the vehicle body and the safety of the occupants. The design of the front grille needs to consider a variety of factors, including the ability to absorb and buffer external impacts, the aesthetics of the decoration and appearance design, and the need to integrate various driver assistance systems and functional components.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The following is for reference. Figures 1-6 According to the embodiment of the present utility model, the grille assembly 100 can selectively block at least a portion of the grille structure 1, so that the air intake of the grille structure 1 can meet the cooling needs of the front of the vehicle, reliably cool components such as the water tank and engine, and reduce the amount of insect corpses adhering to the grille structure 1 after long-distance driving, thereby reducing the difficulty of cleaning the grille structure 1 and improving user satisfaction.

[0025] like Figure 1 As shown, a grille assembly 100 according to an embodiment of the present invention includes: a grille structure 1 and a curtain structure 2.

[0026] The blind curtain structure 2 includes a blind curtain 21, a retractor 22, and a retractor drive 23. The blind curtain 21 is connected to the retractor 22, and the retractor drive 23 is poweredly connected to the retractor 22 to drive the retractor 22 to rotate. When the retractor 22 rotates, it drives the blind curtain 21 to unfold or retract, so as to selectively block at least a portion of the grid structure 1.

[0027] Specifically, the grille assembly 100 includes a grille structure 1 and a screen curtain structure 2. The grille structure 1 is usually located in the center of the front of the vehicle, covering areas such as the water tank and radiator. Air intake holes and guide vanes can be formed on the grille structure 1 to guide airflow into the engine compartment, cool the water tank and engine components, and prevent overheating damage. The grille structure 1 can also be used to block foreign objects such as stones and insects from impacting internal parts, avoiding damage caused by impact. The screen curtain structure 2 is installed on the front side of the grille structure 1 and is used to selectively block at least a part of the grille structure 1. That is, the grille structure 1 can be left unblocked, partially blocked, or completely blocked. The screen curtain structure 2 can also adjust the opening area of ​​the air intake holes of the grille structure 1. In practice, the screen curtain structure 2 can be connected to the grille structure 1 or to the vehicle body to fix the screen curtain structure 2 and ensure its reliable operation.

[0028] When the shielding curtain structure 2 does not obstruct the grille structure 1, meaning the air intake of the grille structure 1 can be fully open, the air intake of the grille structure 1 is at its maximum, resulting in the highest cooling efficiency for components such as the water tank and engine. Thus, the grille structure 1 can be left unobstructed when the temperature of components such as the water tank or engine is high. When the shielding curtain structure 2 completely obstructs the grille structure 1, meaning the air intake of the grille structure 1 is completely blocked, the air intake of the grille structure 1 is at its minimum, resulting in the lowest cooling efficiency for components such as the water tank and engine. Thus, the grille structure 1 can be completely obstructed when the temperature of components such as the water tank or engine is low. When the shielding curtain structure 2 partially obstructs the grille structure 1, meaning the air intake of the grille structure 1 is partially open and partially blocked, the air intake of the grille structure 1 is moderate, which can cool components such as the water tank and engine, but the cooling efficiency is generally low. Thus, the grille structure 1 can be partially obstructed when components such as the water tank or engine have a certain temperature, but are not very high.

[0029] It should be noted that by selectively blocking at least a portion of the grille structure 1 using the shielding curtain structure 2, the air intake of the grille structure 1 can adapt to the cooling needs of the front of the vehicle, thus reliably cooling components such as the radiator and engine. Furthermore, when the shielding curtain structure 2 blocks at least a portion of the grille structure 1, it reduces the amount of insect carcasses and other debris that adhere to the grille structure 1 after long-distance driving, thereby reducing the difficulty of cleaning the grille structure 1.

[0030] Furthermore, the blind curtain structure 2 includes a blind curtain 21, a retractor 22, and a retractor drive 23. The blind curtain 21 has a large area and can selectively cover at least part of the front side of the grille structure 1 to selectively block at least part of the grille structure 1. The retractor 22 can be constructed as a retractor shaft and can rotate relative to the grille structure 1. The blind curtain 21 can be connected to the retractor 22. For example, the retractor 22 can be connected to one side edge of the blind curtain 21 so that the retractor 22 can drive the blind curtain 21 to unfold or retract when it rotates. The rotation directions of the retractor 22 when driving the blind curtain 21 to unfold and retract are opposite.

[0031] Furthermore, when the curtain 21 is rolled up by the retractor 22, the area of ​​the curtain 21 covering the grille structure 1 can be gradually reduced. When the curtain 21 is unrolled by the retractor 22, the area of ​​the curtain 21 covering the grille structure 1 can be gradually increased. Thus, the area of ​​the curtain 21 covering the grille structure 1 can be adjusted, allowing the curtain 21 to selectively cover at least a portion of the grille structure 1. This enables the air intake of the grille structure 1 to meet the cooling requirements of the front of the vehicle and reduces the amount of insect carcasses that adhere to the grille structure 1 after long-distance driving.

[0032] Furthermore, the winding drive 23 provides power and is connected to the winding member 22, allowing the winding drive 23 to supply power to the winding member 22. This means the winding drive 23 can transmit power to the winding member 22 to drive its rotation, thereby enabling the winding member 22 to simultaneously unfold or retract the blind curtain 21. This achieves automatic control of the blind curtain 21 and improves operational convenience. The winding drive 23 can be a motor.

[0033] According to the grille assembly 100 of this utility model embodiment, by power connecting the retracting drive 23 to the retracting member 22, the retracting drive 23 can drive the retracting member 22 to rotate, and the shielding curtain 21 is connected to the retracting member 22, so that the retracting member 22 can drive the shielding curtain 21 to roll up or unfold while rotating, so that at least part of the grille structure 1 can be selectively blocked by the shielding curtain 21, so that the air intake of the grille structure 1 can meet the cooling needs of the front of the vehicle, reliably cool the water tank and engine and other components, and reduce the amount of insect corpses adhering to the grille structure 1 after long-distance driving, which can reduce the cleaning difficulty of the grille structure 1 and improve user satisfaction.

[0034] In some embodiments, the grille assembly 100 further includes a guide 24, which is linked to the retraction drive 23; wherein, the blind curtain 21 includes a fixed side and an unfolded side 211, the fixed side is connected to the retractor 22, the unfolded side 211 is the side edge of the blind curtain 21 away from the retractor 22, the guide 24 is connected to the unfolded side 211, and the guide 24 is adapted to drive the unfolded side 211 to move synchronously when the retraction drive 23 drives the retractor 22 to rotate.

[0035] Specifically, the blind curtain 21 includes a fixed side and an unfolding side 211. The fixed side and the unfolding side 211 are respectively one side edge of the blind curtain 21. The fixed side is connected to the winding shaft, such as by snap-fit, so that the blind curtain 21 is connected to the winding member 22 through the fixed side. When the winding member 22 rotates, it can drive the blind curtain 21 to start winding around the winding member 22 from the fixed side, thus realizing the winding of the blind curtain 21. The unfolding side 211 is the side edge of the blind curtain 21 away from the winding member 22. That is, the fixed side and the unfolding side 211 are a pair of opposite sides on the blind curtain 21. When the blind curtain 21 is finished winding, the unfolding side 211 is located at the outermost side of the blind curtain 21. That is, when the winding member 22 rotates, it can drive the blind curtain 21 to start releasing from the unfolding side 211, thus realizing the unfolding of the blind curtain 21.

[0036] Furthermore, the grille assembly 100 also includes a guide member 24, which serves a guiding function and is linked with the rewind drive member 23. The guide member 24 and the rewind drive member 23 can be connected through other components to enable them to move together. At the same time, the guide member 24 is connected to the unfolding side 211, which means that the guide member 24 can guide the movement of the unfolding side 211 to ensure the accuracy of the movement direction of the unfolding side 211, thereby improving the reliability of the curtain 21 in selectively blocking at least a part of the grille structure 1.

[0037] Furthermore, the guide member 24 is adapted to drive the unfolding side 211 to move synchronously when the winding drive member 23 drives the winding member 22 to rotate. That is, when the winding drive member 23 is running, the winding drive member 23 can not only drive the winding member 22 to rotate to drive the curtain 21 to roll up or unfold, but also drive the guide member 24 to move, so that the guide member 24 can drive the unfolding side 211 to move to realize the rolling up or unfolding of the curtain 21. Moreover, the direction of movement of the unfolding side 211 when the winding member 22 rotates is the same as the direction of movement driven by the guide member 24. Thus, the curtain 21 can be rolled up or unfolded synchronously by the guide member 24 and the winding member 22, which can ensure the working reliability of the curtain 21.

[0038] It should be noted that by connecting the guide member 24 to the unfolding side 211, the guide member 24 can fix the unfolding side 211 when the curtain 21 is unfolded. This can fix the curtain 21 through the unfolding side 211, preventing the curtain 21 from shifting under wind or external forces, and improving the working reliability of the curtain 21.

[0039] In some embodiments, the winding drive 23 is configured as a winding motor, the winding member 22 is configured as a winding shaft, and the motor shaft 231 of the winding motor is poweredly connected to the winding shaft to drive the winding shaft to rotate.

[0040] Specifically, the winding drive 23 is used to provide power to the winding member 22. The winding drive 23 is configured as a winding motor, which is used to convert electrical energy into mechanical energy. The winding motor has a motor shaft 231, which is used to transmit mechanical energy outward to achieve power output. The winding member 22 is configured as a winding shaft, and the motor shaft 231 of the winding motor is poweredly connected to the winding shaft, so that the motor shaft 231 can transmit the mechanical energy of the winding motor to the winding shaft, thereby causing the winding motor to drive the winding shaft to rotate. In turn, the winding shaft can drive the curtain 21 to roll up or unfold while rotating to selectively block at least a part of the grid structure 1.

[0041] The winding shaft has a certain length. Connecting the winding shaft to the fixed side of the curtain 21 can increase the connection length between the two and improve the connection reliability. This can improve the reliability of the winding component 22 driving the curtain 21 to roll up or unfold. The winding motor is designed to be able to rotate in both directions, meaning that the winding motor can drive the winding shaft to rotate in different directions. This allows the winding shaft to drive the curtain to roll up or unfold when rotating in different directions.

[0042] In some embodiments, the grille assembly 100 further includes an auxiliary flywheel 25, the motor shaft 231 of the winding motor is provided with a rotating gear 233, the rotating gear 233 is spaced apart from the auxiliary flywheel 25 and is linked by a transmission chain 26, and the guide member 24 is connected to the transmission chain 26.

[0043] Specifically, the motor shaft 231 of the winding motor is equipped with a rotating gear 233, which can be connected to the motor shaft 231 to enable power transmission between the motor shaft 231 and the rotating gear 233. The rotating gear 233 is linked with the auxiliary flywheel 25 through a transmission chain 26, which enables power transmission between the two and achieves linkage. Furthermore, the rotating gear 233 and the auxiliary flywheel 25 are spaced apart to maintain a certain distance between them, which can avoid interference between them and improve their respective operational reliability.

[0044] The auxiliary flywheel 25 has a similar structure to the rotating gear 233, with teeth formed on its outer periphery. The transmission chain 26 has a similar structure to a bicycle chain and is constructed as a ring. Both the rotating gear 233 and the auxiliary flywheel 25 can be set inside the transmission chain 26 and meshed with the transmission chain 26 respectively. This allows the auxiliary flywheel 25 and the rotating gear 233 to be connected through the transmission chain 26, enabling the rotating gear 233 and the auxiliary flywheel 25 to be linked, that is, they can rotate synchronously.

[0045] Furthermore, the guide member 24 is connected to the transmission chain 26, such as by snap-fit, so as to install and fix the guide member 24, and enable the transmission chain 26 to drive the guide member 24 to move, thereby enabling the guide member 24 to guide the movement of the unfolded side 211.

[0046] In some embodiments, the guide member 24 includes a limiting part 241 and a connecting part 242. One end of the connecting part 242 is connected to the limiting part 241 and the other end passes through the chain hole 261 of the transmission chain 26 and is connected to the unfolded side 211. The limiting part 241 limits and presses against the end face of the transmission chain 26.

[0047] Specifically, the guide member 24 is connected to the unfolded side 211 and the transmission chain 26 respectively, such as Figures 3-4 As shown, the guide member 24 includes a limiting part 241 and a connecting part 242. One end of the connecting part 242 is connected to the limiting part 241, so that the guide member 24 can be a single structure, which can improve the structural strength and operational reliability of the guide member 24. The other end of the connecting part 242 passes through the chain hole 261 of the transmission chain 26 and connects to the unfolding side 211, so that the setting length of the connecting part 242 is greater than the extension length of the chain hole 261. This ensures that the connecting part 242 can pass through from one side of the chain hole 261 to the other side and connect to the unfolding side 211, thereby realizing the connection between the guide member 24 and the unfolding side 211. This allows the guide member 24 to drive the unfolding side 211 to move and can fix the curtain 21 after it is unfolded.

[0048] Furthermore, after the connecting part 242 extends from one side of the chain hole 261 to the other side, the limiting part 241 can be limited and pressed against the end face of the chain hole 261. The length or width of the limiting part 241 can be constructed to be greater than the length or width of the chain hole, so that after the connecting part 242 passes through the chain hole 261, it can be ensured that the limiting part 241 can be limited and pressed against the end face of the transmission chain 26, preventing the limiting part 241 from moving towards the unfolded side 211 and coming out of the chain hole 261. This ensures the reliability of the connection between the guide 24 and the transmission chain 26 and their respective operational reliability.

[0049] Moreover, such as Figure 1 , Figure 3 and Figure 4 As shown, the retractor 22 is disposed above the grille structure 1. The unfolding side 211 of the curtain 21 can move in the up and down direction to realize the unfolding or retraction of the curtain 21. That is, the unfolding direction of the unfolding side 211 is along the vertical direction of the vehicle, and the connecting part 242 passes through the chain hole 261 in the transverse direction of the vehicle. That is, the direction in which the connecting part 242 is inserted into the chain hole 261 is perpendicular to the unfolding direction of the unfolding side 211. This can reduce the setting length of the grille assembly 100 along the vertical direction of the vehicle, which is beneficial for its installation on the vehicle.

[0050] It should be noted that, in practice, the guide member 24 can be made to have a certain thickness in order to avoid interference between the guide member 24 and the transmission chain 26 along the insertion direction of the connecting part 242.

[0051] In some embodiments, the grille assembly 100 further includes a manual operation member 27, which is connected to the drive chain 26 and is used to manually drive the drive chain 26 to move, thereby driving the guide member 24 to push the unfolding side 211 to move.

[0052] Specifically, the manual operation component 27 provides a position for manual operation by the user, meaning the grille assembly 100 can also be operated manually. The manual operation component 27 is connected to the drive chain 26, either by a snap-fit ​​connection or by fitting the manual operation component 27 onto the drive chain 26, allowing power transmission between them. This allows the user to operate the manual operation component 27 to drive the drive chain 26, which in turn drives the guide component 24 to move the unfolding side 211. This enables the curtain 21 to be unfolded or rolled up manually, allowing it to selectively cover at least a portion of the grille structure 1. The manual operation component 27 can be a pull ring or similar material, and can be made of rubber or similar materials to improve user comfort during operation.

[0053] It should be noted that the motor shaft 231 is perpendicular to the winding shaft, and the two are connected by a transmission assembly to achieve power transmission. The transmission assembly can be a set of bevel gears. When the user operates the manual operation component 27 to drive the transmission chain 26, the transmission chain 26 can drive the guide component 24 to push the unfolding side 211 to move. At the same time, the transmission chain 26 can drive the rotating gear 233 to rotate, so that the rotating gear 233 can drive the motor shaft 231 to move. In turn, the motor shaft 231 can drive the winding shaft to rotate through the transmission assembly to realize the winding or unfolding of the curtain 21, which can ensure the reliability of the winding or unfolding of the curtain 21.

[0054] In some embodiments, the rotating gear 233 is provided with a through hole 235, the motor shaft 231 of the winding motor passes through the through hole 235, and the motor shaft 231 and the inner wall of the through hole 235 are connected by a keyway for circumferential transmission.

[0055] Specifically, the rotating gear 233 is connected to the motor shaft 231 of the winding motor. A through hole 235 is provided in the rotating gear 233, through which the motor shaft 231 of the winding motor can be inserted to connect the rotating gear 233 and the motor shaft 231. The motor shaft 231 and the inner wall of the through hole 235 are connected by a keyway for circumferential transmission. A limiting key 232 is provided on one of the inner walls of the motor shaft 231 and the through hole 235, and a limiting groove 236 is provided on the other. Both the limiting key 232 and the limiting groove 236 extend radially along the motor shaft 231, so that when the rotating gear 233 is sleeved on the motor shaft 231, the limiting key 232 extends into the limiting groove 236, so that power can be transmitted between the motor shaft 231 and the rotating gear 233 through the cooperation of the limiting key 232 and the limiting groove 236.

[0056] In such Figure 5 In the embodiment shown, a limiting key 232 is provided on the outer side of the motor shaft 231, and a limiting groove 236 is formed on the inner wall of the through hole 235. When the motor shaft 231 is inserted into the through hole 235, the limiting key 232 can extend into the limiting groove 236, so that the motor shaft 231 and the rotating gear 233 can be circumferentially driven. A bushing 234 is fixed inside the rotating gear 233, and the through hole 235 is formed inside the bushing 234, so that the motor shaft 231 can be inserted into the bushing 234 to realize the connection between the motor shaft 231 and the rotating gear 233. The bushing 234 can reduce the wear of the rotating gear 233 and help extend the service life of the rotating gear 233.

[0057] In some embodiments, there are two winding motors, and the two winding motors are respectively poweredly connected to both ends of the winding shaft; wherein, there are two guide members 24, each corresponding to one of the two winding motors, and the two guide members 24 are respectively connected to both ends of the unfolded side 211.

[0058] Specifically, the take-up motor is used to drive the take-up component 22 to rotate. By setting two take-up motors, the take-up component 22 can be driven to rotate simultaneously by the two take-up motors, which can improve the reliability of the take-up component 22 rotating under the drive of the take-up motors. Furthermore, by power-connecting the two take-up motors to the two ends of the take-up shaft respectively, the two take-up motors can be set apart, or the two take-up motors can be connected to different positions on the take-up shaft respectively. This allows the two take-up motors to drive the take-up shaft to rotate simultaneously from two positions, which can improve the stability of the take-up shaft rotating under the drive of the take-up motors and avoid interference between the two take-up motors, thereby improving their respective working reliability.

[0059] There are two guide members 24, each corresponding to one of the two winding motors. The two guide members 24 are connected to the winding motors via a transmission chain 26, and are respectively set on both sides of the winding shaft. The two guide members 24 are then connected to both ends of the unfolded side 211, allowing the two guide members 24 to guide the movement of the unfolded side 211 at two positions simultaneously. This improves the reliability and stability of guiding the movement of the unfolded side 211. When the curtain 21 is unfolded, the two guide members 24 can simultaneously fix the curtain 211 at both ends of the unfolded side 211, effectively preventing the curtain 21 from shifting under wind or external forces, thus improving the working reliability of the curtain 21.

[0060] It should be noted that, in practice, the two guide members 24 can be connected to different sides or the same side of the two drive chains 26 respectively, that is, the two winding motors can rotate in the same direction or in opposite directions to drive the winding shaft to rotate reliably.

[0061] It should be noted that, in practice, both retractable motors can be connected to the vehicle's control module, allowing the control module to simultaneously control the start or stop of both motors. A temperature sensor can be installed on the rear side of the grille structure to monitor the temperature of surrounding components in real time. The temperature sensor is electrically connected to the control module, allowing the sensor's detection results to be sent to the control module via Ethernet or CAN data. The control module can then control the two retractable motors based on the temperature sensor's detection results. The temperature sensor has a set value; when the temperature sensor's detection result is lower than the set value, the shielding curtain 21 can be controlled to unfold to shield at least a portion of the grille structure 1; when the temperature sensor's detection result is higher than the set value, the shielding curtain 21 can be controlled to retract to avoid shielding the grille structure 1.

[0062] Specifically, such as Figure 6As shown, when the vehicle power is turned on, the control system can be activated via a soft switch or a hard switch. When the temperature sensor reading is lower than the set value, the control module can control two retractor motors to operate simultaneously, driving the retractor shaft to rotate and unfold the curtain 21. When the temperature sensor reading is higher than the set value, the control module can control two retractor motors to operate simultaneously, driving the retractor shaft to rotate and retract the curtain 21. Through this process, the air intake of the grille structure 1 can meet the cooling needs of the front of the vehicle, reliably cooling components such as the water tank and engine. It can also reduce the amount of insect corpses adhering to the grille structure 1 after long-distance driving, reducing the difficulty of cleaning the grille structure 1 and improving user satisfaction.

[0063] Furthermore, there is only one manual operating component 27, which can be installed on any of the transmission chains 26. When the winding motor is damaged or cannot operate, the winding or unfolding of the shielding curtain 21 can be controlled manually to ensure the reliability of the shielding curtain 21 in selectively shielding at least a part of the grid structure 1.

[0064] In some embodiments, the retractor is formed with a snap-fit ​​groove 221, and the fixed side engages with the snap-fit ​​groove 221 to allow the blind curtain 21 to be detachably connected to the retractor.

[0065] Specifically, such as Figure 2 As shown, a locking groove 221 can be formed inside the retractor shaft. The locking groove 221 is used to engage with the fixed side of the blind curtain 21, so as to connect the retractor shaft and the blind curtain 21 through the fixed side. The fixed side is engaged with the locking groove 221. For example, locking grooves can be formed at both ends of the locking groove 221, and at least a portion of both ends of the fixed side is engaged with the two locking grooves respectively. This enables the connection between the retractor shaft and the fixed side, allowing the retractor shaft to drive the blind curtain. The 21 can be rolled up or unrolled, and the snap-fit ​​connection method allows the curtain 21 to be detachably connected to the roll-up shaft. This makes it easy to connect or separate the curtain 21 from the roll-up shaft, and also makes it easy to install or remove the curtain 21. When the curtain 21 is connected to the roll-up shaft, it can selectively block at least a part of the grid structure 1. When the curtain 21 is separated from the roll-up shaft, it can be removed and cleaned separately.

[0066] Furthermore, it should be noted that the grille assembly 100 of this utility model is installed on the front side of the vehicle. A mounting base can be provided, and the grille assembly 100 can be installed on the front side of the vehicle as a whole through the mounting base. Alternatively, multiple brackets can be used to connect the winding shaft, winding motor, and auxiliary flywheel 25 to the vehicle body. Both methods can achieve the installation of the grille assembly 100 on the vehicle, ensuring its reliable operation. In addition, the blind curtain 21 can be made of plastic material, which helps to reduce the installation cost.

[0067] This utility model also proposes a vehicle.

[0068] The vehicle according to the embodiments of this utility model includes a grille assembly 100 of any of the above embodiments. The retractable shaft can be driven to rotate manually or automatically to retract or unfold the shielding curtain 21, allowing the shielding curtain 21 to selectively block at least a portion of the grille structure 1. This enables the air intake of the grille structure 1 to meet the cooling needs of the front of the vehicle, reliably cooling components such as the water tank and engine. Furthermore, it reduces the amount of insect carcasses adhering to the grille structure 1 after long-distance driving, lowering the difficulty of cleaning the grille structure 1 and improving user satisfaction.
