Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts, and in particular relates to an automobile grille. Background Art

[0002] The car grille is a key component of the vehicle, used to provide air intake for the engine and dissipate heat for the internal components of the car.

[0003] At present, the existing automobile grilles can usually only adjust the air intake volume. For example, a Chinese patent application document with publication number CN111055675A discloses an automobile air intake grille assembly, in which the baffle assembly inside the automobile air intake grille is arranged separately from the grille. The baffle assembly is slidably arranged behind the grille. Driven by a two-way screw mechanism and a motor, the baffle assembly can be extended and retracted. The different extension and retraction amounts of the baffle assembly can change the projection area of ​​the baffle assembly on the grille, thereby controlling the air intake volume of the automobile grille to achieve the effect of regulating the air intake flow.

[0004] For example, the Chinese patent application document with publication number CN113978239A discloses an active air intake structure of an automobile grille, an automobile and a grille air intake control method thereof. The automobile active air intake grille is provided with a guide rail bracket and a blade assembly, and the blade assembly is slidably connected to a sliding groove on the guide rail bracket. Driven by a driving device, the blade assembly can move up and down along the sliding groove, and the driving device drives the blade assembly to move up and down to achieve the effect of adjusting the intake flow rate.

[0005] In summary, although the air intake volume of the above-mentioned automobile air intake grille can be adjusted, the above-mentioned automobile air intake grille cannot intercept rainwater passing through the grille on rainy days. As the amount of rainwater passing through the grille increases on rainy days, it will cause erosion to the components inside the grille, and the entry of rainwater will increase the humidity of the air entering the engine, affecting the engine's working efficiency.

[0006] Based on this, there is an urgent need for a car grille that can both adjust the air intake and intercept rainwater passing through the grille. Summary of the invention

[0007] In order to solve the technical problem that the automobile air intake grille cannot intercept rainwater passing through the grille on rainy days and cannot adjust the air intake volume of the grille, the present invention provides an automobile grille that can both adjust the air intake volume and intercept rainwater passing through the grille.

[0008] To achieve the above object, the present invention adopts the following technical solution: An automobile grille, comprising: Grille housing; A flow guide component is arranged in a grille housing, the flow guide component comprises a sliding baffle and a flow guide telescopic assembly, the sliding baffle extends along the length direction of the grille housing, opposite ends of the sliding baffle are respectively slidably connected to opposite sides of the grille housing, the flow guide telescopic assembly comprises a rotating member and a flow guide telescopic member, the rotating member and the sliding baffle have the same extension direction, opposite ends of the rotating member are respectively rotatably connected to opposite side walls of the grille housing, the rotating member is located between the sliding baffle and the air inlet port of the grille housing, the rotating member and the sliding baffle are connected via the telescopic member, the flow guide telescopic member closes the gap between the sliding baffle and the rotating member, and the flow guide telescopic member can be telescoped relative to the rotating member; An interception groove is provided in the grille housing, the extension direction of the interception groove is the same as the extension direction of the sliding baffle, the opposite ends of the interception groove are respectively connected to the opposite sides of the grille housing, and the interception groove is provided between the sliding baffle and the air inlet port of the grille housing; A driving assembly, disposed on the grille housing, for driving the sliding baffle to slide vertically; The vertical sliding of the sliding baffle drives the flow-guiding telescopic member to drive the rotating member to rotate, so as to guide the rainwater entering the grille shell from the air inlet port into the intercepting groove.

[0009] Beneficial effects: 1. When the present invention is used, the driving assembly drives the sliding baffle to slide along the vertical direction of the grille shell, and the guide telescopic assembly is driven by the sliding baffle, and the rotating part rotates relative to the grille shell. The guide telescopic part is extended or shortened as the rotating part rotates, thereby adjusting the air intake gap between the interception groove and the sliding baffle. Since the outside air of the grille enters the engine compartment of the car from the air intake port of the grille through the air intake gap between the interception groove and the sliding baffle, adjusting the air intake gap between the interception groove and the sliding baffle is to adjust the air intake volume of the car grille. If the external environment is good and there is no rain, the driving assembly drives the sliding baffle to slide upward along the vertical direction of the grille shell, and the rotating part rotates relative to the grille shell. The guide telescopic part is shortened as the rotating part rotates, so that the air intake gap between the interception groove and the sliding baffle is adjusted to the maximum, thereby increasing the air intake volume of the car grille.

[0010] 2. When encountering rainy weather, the sliding baffle slides downward along the vertical direction of the grille shell under the drive of the driving component. Driven by the sliding baffle, the rotating part rotates relative to the grille shell, and the guide telescopic part extends with the rotation of the rotating part, so that the air intake gap between the sliding baffle and the interception groove is adjusted to the minimum. At this time, the angle of the guide telescopic component and the air intake port of the grille shell entering the air flow reaches the maximum, so that the rainwater entering the grille shell from the air intake port of the grille shell enters the interception groove for interception and filtration under the guidance of the guide telescopic component, effectively preventing the rainwater entering the grille shell from causing the air humidity of the engine to increase, thereby affecting the engine working efficiency.

[0011] Furthermore, the rotating member is a rotating baffle, and the flow-guiding telescopic member is a flow-guiding telescopic plate. The rotating baffle is provided with rotating parts at the opposite ends, and the two rotating parts are respectively rotatably connected to the opposite side walls in the grille shell. The rotating baffle is provided with a sliding cavity running through the opposite end faces at both ends thereof. A sliding groove communicating with the sliding cavity is provided on a side wall of the rotating baffle facing the sliding baffle, and an extension direction of the sliding groove is the same as an extension direction of the sliding baffle. The flow-guiding telescopic plate is connected to the sliding baffle on a side facing the sliding baffle, and the flow-guiding telescopic slide plate is penetrated into the sliding cavity on a side facing away from the sliding baffle. Beneficial effect: The structural stability of the diversion telescopic member during rainwater diversion can be improved, and the rainwater can be effectively guided.

[0012] Furthermore, an anti-slip portion is provided on the second side of the guide telescopic plate, and the anti-slip portion prevents the guide telescopic plate from escaping from the sliding cavity.

[0013] Beneficial effect: It can ensure that the diversion telescopic component will not separate during extension and retraction, thereby ensuring the integrity of the diversion telescopic component structure and not affecting the guiding effect of rainwater during operation.

[0014] Furthermore, the sliding baffle is provided with connecting parts at the opposite ends of the surface of the guide telescopic plate, the connecting parts protrude toward the direction of the guide telescopic plate, and the connecting parts are provided with a long groove along the extension direction of the intercepting groove. The long groove extends in the vertical direction, and the long groove passes through the connecting part along the extension direction of the intercepting groove. The opposite ends of the guide telescopic plate are provided with sliding parts, and the sliding parts slide in the long groove along the vertical direction.

[0015] Beneficial effect: The limit expansion and contraction of the guide expansion plate can be increased or decreased, thereby changing the angle of the airflow entering the air inlet to enhance the guiding effect of the airflow. Furthermore, a projection area of ​​the sliding baffle in the vertical direction partially overlaps with a projection area of ​​the intercepting groove in the vertical direction.

[0016] Beneficial effect: It ensures that rainwater can be guided into the interception groove for interception, rather than directly passing through the air intake gap between the sliding baffle and the interception groove.

[0017] Furthermore, the projection area of ​​the sliding baffle in the vertical direction occupies 1 / 2 of the projection area of ​​the intercepting groove in the vertical direction.

[0018] Beneficial effect: Improve the efficiency of intercepting rainwater.

[0019] Furthermore, the interception trough includes a drainage trough and a filter net, the opposite ends of the drainage trough are connected to the opposite ends of the grille shell, and the filter net is arranged in the drainage trough to filter rainwater entering the drainage trough.

[0020] Beneficial effect: Impurities filtered by the filter will not enter the engine compartment of the car.

[0021] Furthermore, drainage channels are arranged inside opposite sides of the grille shell, and the two drainage channels are respectively communicated with opposite ends of the drainage groove, and the drainage channels are used to discharge water in the drainage groove out of the grille shell.

[0022] Beneficial effect: Rainwater filtered by the interception trough is collected and discharged out of the car grille.

[0023] Furthermore, the drainage groove presents a tapered structure along the extension direction of the sliding baffle, which is high in the middle and low at both ends.

[0024] Beneficial effect: The filtered rainwater can flow autonomously to both sides of the gutter and be discharged from the grille shell through the drainage channel.

[0025] Furthermore, two opposite side walls in the grille shell are provided with vertical sliding grooves, and opposite end surfaces of the sliding baffle slide along the sliding grooves.

[0026] Beneficial effect: The gap between the guide component and the shell can be reduced, so that rainwater can only be guided into the interception groove by the guide component, further improving the interception effect of rainwater.

[0027] The effective effects of the automobile grille of the present invention are: 1. When the automobile grille of the present invention is in use, if the external environment is good and there is no rain, the driving assembly drives the sliding baffle to slide upward along the vertical direction of the grille shell, the rotating part rotates relative to the grille shell, and the guide telescopic part is shortened as the rotating part rotates, so that the air intake gap between the interception groove and the sliding baffle is adjusted to the maximum, thereby increasing the air intake amount of the automobile grille; when encountering rainy weather, the driving assembly slides the baffle downward along the vertical direction of the grille shell, and driven by the sliding baffle, the rotating part rotates relative to the grille shell, and the guide telescopic part is extended as the rotating part rotates, so that the air intake gap between the sliding baffle and the interception groove is adjusted to the minimum, at which time the angle of the guide telescopic assembly and the air intake port of the grille shell entering the airflow reaches the maximum, so that rainwater entering the grille shell from the air intake port of the grille shell enters the interception groove for interception and filtration under the guidance of the guide telescopic assembly, effectively preventing the rainwater entering the grille shell from causing the air humidity of the engine to increase, thereby affecting the working efficiency of the engine.

[0028] 2. When intercepting rainwater, the air intake gap between the sliding baffle and the interception groove reaches the minimum state, and a certain angle is formed between the telescopic assembly and the interception groove at this time, that is, the rotating baffle and the guide telescopic plate are in an inclined state. Since the projection area of ​​the sliding baffle in the vertical direction partially overlaps with the projection area of ​​the interception groove in the vertical direction, after the rainwater enters the grille shell from the air intake port of the grille shell, it is guided to the interception groove by the inclination of the rotating baffle and the guide telescopic member, so that the rainwater entering the grille shell is guided to the interception groove under the blocking effect of the sliding baffle, the rotating baffle and the guide telescopic plate and the inclined guide effect of the rotating baffle and the guide telescopic plate, thereby preventing the rainwater entering the grille shell from entering the engine compartment of the car, resulting in an increase in the air humidity of the engine and affecting the engine working efficiency.

[0038] Reference Figure 1-Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Figure 16-Figure 21, the air guide telescopic assembly 6 includes a rotating member and an air guide telescopic member, the rotating member also extends in the horizontal direction along the length of the grille housing 1, so that the extension direction of the rotating member is the same as the extension direction of the sliding baffle 5; each rotating member is located in each groove 25, and the opposite ends of the rotating member are respectively rotatably connected to the opposite side walls of the grille housing 1, that is, one end of the rotating member is rotatably connected to the baffle fixing groove 11 on one side of the grille housing 1, and the other end of the rotating member is rotatably connected to the baffle fixing groove 11 on the other side of the grille housing 1. Of course, the rotating member is located between the sliding baffle 5 and the air inlet port 4 of the grille housing 1, and the rotating member is connected to the sliding baffle 5 through the air guide telescopic member, the air guide telescopic member closes the gap between the sliding baffle 5 and the rotating member, and the air guide telescopic member can be telescoped relative to the rotating member. Specifically, the rotating member is a rotating baffle 7, and the flow-guiding telescopic member is a flow-guiding telescopic plate 8. The extending direction of the rotating baffle 7 is the same as the extending direction of the sliding baffle 5. The rotating baffle 7 is provided with rotating parts at opposite ends, and the two rotating parts are respectively rotatably connected to the opposite side walls in the grille shell 1, that is, the rotating baffle 7 is rotatably connected to the baffle fixing groove 11 through the rotating part, the baffle fixing groove 11 is a cylindrical hole, and the rotating part is a rotating shaft. In addition, a sliding cavity 15 is provided inside the rotating baffle 7 and passes through the opposite end faces of the rotating baffle 7. A sliding groove 16 communicating with the sliding cavity 15 is provided on a side wall of the rotating baffle 7 facing the sliding baffle 5. The extension direction of the sliding groove 16 is the same as the extension direction of the sliding baffle 5. The side of the guide telescopic plate facing the sliding baffle is the first side 801 of the guide telescopic plate, and the side of the guide telescopic slide plate facing away from the sliding baffle is the second side 802 of the guide telescopic slide plate. The first side 801 of the guide telescopic plate is connected to the sliding baffle 5, and the second side 802 of the guide telescopic plate is slidably penetrated into the sliding cavity 15. The second side 802 of the guide telescopic plate is provided with an anti-slip portion, which prevents the guide telescopic plate 8 from detaching from the sliding cavity 15.

[0039] Reference Figure 16-Figure 21 Furthermore, the anti-slip portion is connected to the second side 802 of the guide telescopic plate to form a "T"-shaped anti-slip structure 17; the sliding cavity 15 and the "T"-shaped anti-slip structure 17 can ensure that when rainwater impacts the guide telescopic member, the "T"-shaped anti-slip structure 17 will not swing, thereby improving the structural stability of the guide telescopic plate 8 when diverting rainwater, ensuring that the guide telescopic assembly 6 will not separate when it is extended, and then ensuring the integrity of the structure of the guide telescopic assembly 6, without affecting the guiding effect of rainwater during operation.

[0040] Reference Figure 5-Figure 10 , Figure 13-Figure 21, cylindrical sliding parts are provided at both ends of the first side 801 of the guide telescopic plate, and connecting parts are provided at the opposite ends of the surface of the sliding baffle 5 facing the guide telescopic plate 8. The connecting part protrudes in the direction of the guide telescopic plate 8, and a long groove 14 is opened on the connecting part along the extension direction of the interception groove 3. The long groove 14 is a waist-shaped groove, and the long groove 14 extends in the vertical direction of the grille shell. The long groove 14 passes through the connecting part in the direction of the interception groove 3. The two cylindrical sliding parts on the guide telescopic plate 8 are respectively slidably connected with the long grooves 14 on the opposite ends of the sliding baffle 5. When the sliding baffle 5 slides up and down, the cylindrical sliding part slides up and down along the long groove 14. When the cylindrical sliding part slides to the lowest end of the long groove 14, the extension of the guide telescopic plate 8 reaches the maximum; when the cylindrical sliding part slides to the top of the long groove 14, the extension of the guide telescopic plate 8 reaches the minimum; therefore, the long groove 14 can increase or decrease the maximum extension amount of the guide telescopic plate 8, and then change the incoming airflow angle of the air inlet port 4 to enhance the airflow guiding effect.

[0041] It should be noted that if Fig.10 As shown, since the rotating member is located in the groove 25, when the extension of the guide telescopic plate 8 is at the minimum state, the guide telescopic assembly 6 is horizontally stored in the groove 25, achieving the effect of saving space.

[0042] Figure 1-Figure 6 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 The interception groove 3 is arranged between the sliding baffle 5 and the air inlet port 4 of the grille housing 1, and the interception groove 3 extends along the length direction of the grille housing 1; the number of the interception grooves 3 is the same as the number of the guide components, and one interception groove 3 corresponds to one guide component. The interception groove 3 includes a drainage groove 19 and a filter screen 18. The drainage groove 19 extends along the length direction of the grille housing 1. The drainage groove 19 is provided on the upper surface of the grille baffle 12, and the bottom wall of the grille housing 1 is also provided with a drainage groove 19. One drainage groove 19 corresponds to one guide telescopic assembly 6. The opposite ends of the drainage groove 19 are connected to the opposite ends of the grille housing 1. Of course, the opposite ends of the drainage groove 19 are respectively connected to the drainage channels 20 on the opposite sides of the grille housing 1. Further, the drainage groove 19 is provided with connecting holes 21 at both ends extending to the two side walls of the grille housing 1. The drainage groove 19 is connected to the drainage channel 20 through the connecting holes 21, so that the rainwater in the drainage groove 19 can be discharged from the drainage channel 20. In this way, the drainage channel 20 collects rainwater from the interception groove 3, and the collected rainwater is discharged out of the vehicle grille through the drainage channel 20. In addition, the drainage groove 19 presents a tapered structure with a high middle and low ends along the extension direction of the sliding baffle 5, which is conducive to the rainwater in the drainage groove 19 to automatically flow to the drainage channel 20.

[0043] Reference Figure 1-Figure 13 , the filter 18 is in the shape of a rectangular opening, and both ends of the filter 18 are detachably fixed on the filter fixing groove 13 of the grille shell 1, which is convenient for replacing the filter 18. Of course, one end of the filter 18 is detachably fixed in the filter fixing groove 13 on one side of the grille shell 1, and the other end of the filter 18 is detachably fixed in the filter fixing groove 13 on the other side of the grille shell 1. Among them, the filter 18 is embedded in the drainage groove 19. Of course, there is a distance between the filter 18 and the drainage groove 19 to prevent the bottom surface of the filter 18 from fitting with the bottom surface of the drainage groove 19. The extension direction of the filter 18 is the same as the extension direction of the drainage groove 19. The filter 18 is used to filter rainwater entering the drainage groove 19. In addition, since the filter 18 is embedded in the drainage groove 19, the impurities filtered by the filter 18 will not enter the engine compartment of the car. Refer to Figure 1-Figure 10 , Fig.13 , a driving assembly is arranged on the grille housing 1, and is used to drive the sliding baffle 5 to slide vertically. Specifically, the driving assembly includes a driving motor 22 and a screw rod 23. The driving motor 22 is arranged in the motor fixing slot 9 on the grille housing 1. The screw rod 23 is drivingly connected to the output shaft of the driving motor 22, and the screw rod 23 extends along the vertical direction of the grille housing 1 to the bottom and is rotationally connected to the bottom of the grille housing 1. The screw rod 23 is also penetrated through a plurality of sliding baffles 5 and connected with a plurality of threads. The driving motor 22 drives the screw rod 23 to drive each sliding baffle 5 to move in the vertical direction. The driving assembly can be arranged in two or more groups, so that the driving force for driving the sliding baffle 5 and the stability of the sliding baffle 5 moving in the vertical direction can be improved.

[0044] In summary, the driving motor 22 drives the screw rod 23 to rotate, and the rotation of the screw rod 23 drives the sliding baffle 5 to slide vertically, thereby driving the diversion telescopic member to drive the rotating member to rotate, so as to guide the rainwater entering the grille shell 1 from the air inlet port 4 into the interception groove 3 for interception. Specifically, it can be understood that when the automobile grille of the present invention is used, the driving component drives the sliding baffle 5 to slide along the vertical direction of the grille shell 1, and the diversion telescopic component 6 is driven by the sliding baffle 5, and the rotating member rotates relative to the grille shell 1, and the diversion telescopic member is extended or shortened with the rotation of the rotating member, thereby adjusting the air intake gap 2 between the interception groove 3 and the sliding baffle 5, and because the outside air of the grille enters the engine compartment of the car from the air inlet port 4 of the grille through the air intake gap 2 between the interception groove 3 and the sliding baffle 5, adjusting the air intake gap 2 between the interception groove 3 and the sliding baffle 5 is to adjust the air intake amount of the automobile grille. If the external environment is good and there is no rain, the sliding baffle 5 is driven by the driving assembly to slide upward along the vertical direction of the grille shell 1, the rotating part rotates relative to the grille shell 1, and the guide telescopic part is shortened as the rotating part rotates, so that the air intake gap 2 between the intercepting groove 3 and the sliding baffle 5 is adjusted to the maximum, thereby increasing the air intake amount of the automobile grille.

[0045] When intercepting rainwater, the air intake gap 2 between the sliding baffle 5 and the interception groove 3 reaches the minimum state, and a certain angle is formed between the telescopic assembly and the interception groove 3 at this time, that is, the rotating baffle 7 and the guide telescopic plate 8 are in an inclined state. Since the projection area of ​​the sliding baffle 5 in the vertical direction partially overlaps with the projection area of ​​the interception groove 3 in the vertical direction, after the rainwater enters the grille shell 1 from the air intake port 4 of the grille shell 1, it is guided to the interception groove 3 by the inclination of the rotating baffle 7 and the guide telescopic member, so that the rainwater entering the grille shell 1 is guided to the interception groove 3 under the blocking effect of the sliding baffle 5, the rotating baffle 7 and the guide telescopic plate 8 and the inclined guide effect of the rotating baffle 7 and the guide telescopic plate 8, so as to prevent the rainwater entering the grille shell 1 from entering the engine compartment of the car, resulting in an increase in the air humidity of the engine and affecting the engine working efficiency.

[0046] Reference Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.13 When encountering rainy weather, under the drive of the driving component, the sliding baffle 5 slides downward along the vertical direction of the grille shell 1. Driven by the sliding baffle 5, the rotating member rotates relative to the grille shell 1, and the guide telescopic member extends with the rotation of the rotating member, so that the air intake gap 2 between the sliding baffle 5 and the interception groove 3 is adjusted to the minimum. At this time, the angle of the guide telescopic component 6 and the air intake port 4 of the grille shell 1 entering the air flow reaches the maximum, so that the rainwater entering the grille shell 1 from the air intake port 4 of the grille shell 1 enters the interception groove 3 under the guidance of the guide telescopic component 6 for interception and filtration, effectively preventing the rainwater entering the grille shell 1 from causing the air humidity of the engine to increase, thereby affecting the engine working efficiency.

[0047] Reference Figure 1-Figure 10 , Fig.13 In addition, the sliding baffle 5 slides along the slide groove 10 and the opposite ends of the rotating baffle 7 are respectively located in the baffle fixing grooves 11 on the opposite sides of the grille shell 1, and the guide telescopic plate 8 closes the gap between the rotating baffle 7 and the sliding baffle 5, thereby reducing the gap between the guide component and the shell, so that rainwater can only be guided by the guide component to the interception groove 3, further improving the interception effect of rainwater.

[0048] Reference Fig.13 , Fig. 22 , Fig.23 , Fig.24In addition, the projection area of ​​the sliding baffle 5 in the vertical direction partially overlaps with the projection area of ​​the interception groove 3 in the vertical direction, which can ensure that the rainwater can be guided into the interception groove 3 for interception instead of directly passing through the air intake gap 2 between the sliding baffle 5 and the interception groove 3, thereby improving the efficiency of rainwater interception.

[0049] Reference Fig.13 , Fig. 22 , Fig.23 , Fig.24 Furthermore, the vertical projection area of ​​the sliding baffle 5 occupies 1 / 2 of the vertical projection area of ​​the interception groove 3, further improving the interception efficiency of rainwater. Of course, in other embodiments, the vertical projection area of ​​the sliding baffle 5 may also occupy 1 / 3 of the vertical projection area of ​​the interception groove 3, which is not limited here.

[0050] The working principle of the automobile grille of the present invention: When wading or in rainy weather, the screw rod 23 rotates under the drive of the driving motor 22, and the multiple groups of sliding baffles 5 connected to the screw rod 23 slide downward along the slide groove 10 to the maximum limit, and the sliding baffle 5 slides downward. The guide telescopic assembly 6 is driven by the sliding baffle 5, and the rotating baffle 7 rotates relative to the grille shell 1. The "T"-shaped anti-detachment structure 17 of the guide telescopic plate 8 slides in the sliding cavity 15 of the rotating baffle 7, and the cylindrical sliding part of the guide telescopic plate 8 slides to the top of the long groove 14. The guide telescopic plate 8 extends with the rotation of the rotating part. At this time, the guide telescopic plate 8 and the rotating baffle 7 are in an inclined state, and the air intake gap 2 between the intercepting groove 3 and the sliding baffle 5 is adjusted to the minimum state. At this time, the air intake volume of the automobile grille is minimized. In this state, when rainwater enters the grille housing 1 through the air inlet port 4, the rainwater will flow into the interception groove 3 along the sliding baffle 5 under the guidance of the inclination of the guide telescopic plate 8 and the rotating baffle 7, and then be filtered by the filter screen 18 of the interception groove. The filtered rainwater will flow to the drainage channels 20 on both sides of the grille and be discharged outside the grille under the taper of the drainage groove 19. It can be seen that the automobile grille of the present invention will not affect the airflow entering the engine compartment of the automobile through the air intake gap 2 while blocking rainwater from entering the engine compartment of the automobile.

[0051] In rainless weather, when it is necessary to control the air intake of the automobile grille to reach the maximum, the drive motor 22 is started, and the drive motor 22 drives the screw rod 23 to rotate, so that the multiple sets of sliding baffles 5 threadedly connected to the screw rod 23 slide upward along the slide groove 10 to the maximum limit position, and the guide telescopic assembly 6 is driven by the sliding baffle 5, and the rotating baffle 7 rotates relative to the grille shell 1, and the "T"-shaped anti-slip structure 17 of the guide telescopic plate 8 slides in the sliding cavity 15 of the rotating baffle 7, and the cylindrical sliding part of the guide telescopic plate 8 slides along the vertical direction of the grille shell 1 to the lower end of the long groove 14, and the guide telescopic plate 8 is shortened with the rotation of the rotating part. At this time, the guide telescopic plate 8 and the rotating baffle 7 are in a horizontal state, so that the air intake gap 2 between the intercepting groove 3 and the sliding baffle 5 reaches the maximum state.

[0052] In summary, the air intake of the automobile grille is achieved by adjusting the air intake gap 2 between the interception groove 3 and the sliding baffle 5; in rainless weather, the size of the air intake gap 2 can be adjusted according to the actual working conditions to achieve the effect of flexibly controlling the air intake of the automobile grille.

[0053] In summary, the automobile grille of the present invention can both adjust the air intake volume and intercept rainwater passing through the grille, so that rainwater entering the grille shell 1 from the air intake port 4 of the grille shell 1 enters the interception groove 3 under the guidance of the guide telescopic component 6 for interception and filtration, effectively preventing the rainwater entering the grille shell 1 from increasing the air humidity of the engine and affecting the engine working efficiency.

[0054] Embodiment 2 The difference between this embodiment and the first embodiment is that the structure of the flow guiding telescopic component 6 is different, that is, the structure of the rotating part and the flow guiding telescopic part is different.

[0055] Reference Fig.13 , Fig.25 , Fig.26 , Fig. 27 The diversion telescopic assembly 6 of this embodiment adopts a rolling curtain structure 26. Specifically, the rotating part is a rotating shaft 261, and the diversion telescopic part is a waterproof cloth 262. The waterproof cloth 262 is wound on the rotating part, and the waterproof cloth 262 is connected to the sliding baffle 5. During operation, the driving motor 22 drives the screw rod 23 to rotate, and drives the sliding baffle 5 to slide up and down along the slide groove 10. Driven by the sliding baffle 5, the waterproof cloth 262 is stretched and extended, and the rotating part rotates. In this way, driven by the sliding baffle 5, the waterproof cloth 262 will form an angle with the airflow and rainwater entering the grille from the air intake port 4. After the airflow or rainwater enters the interior, under the guidance of the waterproof cloth 262, the rainwater will be guided to the interception groove 3 for filtration, and the airflow will enter the engine compartment through the air intake gap 2. Similarly, this embodiment can also guide the incoming airflow and rainwater.

Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
