Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts, and particularly 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 car's internal components.

[0003] At present, 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. 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 projected 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 for an automobile grille, an automobile and a method for controlling the air intake of the automobile grille. The automobile active air intake grille is provided with a guide rail bracket and a blade assembly. 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. The driving device drives the blade assembly to move up and down to achieve the effect of adjusting the air intake flow.

[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 regulate 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 solutions:

[0009] An automobile grille, comprising:

[0010] grille housing;

[0011] An air guide component is arranged in a grille housing, the air guide component includes a sliding baffle and an air guide telescopic assembly, the sliding baffle extends along the length direction of the grille housing, opposite ends of the sliding baffle are slidably connected to opposite sides of the grille housing respectively, the air guide telescopic assembly includes a rotating member and an air guide telescopic member, the rotating member and the sliding baffle extend in the same direction, opposite ends of the rotating member are rotatably connected to opposite side walls of the grille housing respectively, 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 air guide telescopic member, the air guide telescopic member closes the gap between the sliding baffle and the rotating member, and the air guide telescopic member can be telescoped relative to the rotating member;

[0012] 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;

[0013] A driving assembly, provided on the grille housing, for driving the sliding baffle to slide vertically;

[0014] The vertical sliding of the sliding baffle drives the diversion 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 interception groove.

[0015] Beneficial effects:

[0016] 1. When the present invention is used, the driving assembly drives the sliding baffle to slide along the vertical direction of the grille housing. Driven by the sliding baffle, the rotating member of the diverter telescopic assembly rotates relative to the grille housing. The diverter telescopic member extends or shortens as the rotating member 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 vehicle from the grille's air intake port 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 equivalent to adjusting the air intake volume of the vehicle 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 housing. The rotating member rotates relative to the grille housing. The diverter telescopic member shortens as the rotating member 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 vehicle grille.

[0017] 2. When encountering rainy weather, the sliding baffle slides downward along the vertical direction of the grille shell under the drive of the driving assembly. Driven by the sliding baffle, the rotating part rotates relative to the grille shell, and the guide telescopic part extends 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 this time, the angle of the guide telescopic assembly 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 assembly, effectively preventing the rainwater entering the grille shell from increasing the air humidity of the engine and affecting the engine working efficiency.

[0018] Furthermore, the rotating part is a rotating baffle, and the diverter telescopic part is a diverter telescopic plate. The opposite ends of the rotating baffle are provided with rotating parts, and the two rotating parts are respectively rotatably connected to the opposite side walls in the grille shell. The interior of the rotating baffle is provided with a sliding cavity that passes through the opposite end faces of the rotating baffle itself, and a sliding groove that communicates with the sliding cavity is provided on a side wall of the rotating baffle facing the sliding baffle. The extension direction of the sliding groove is the same as the extension direction of the sliding baffle, and the side of the diverter telescopic plate facing the sliding baffle is connected to the sliding baffle, and the side of the diverter telescopic plate facing away from the sliding baffle is passed through the sliding cavity.

[0019] Beneficial effect: The structural stability of the diversion telescopic member when diverting rainwater can be improved, and the rainwater can be effectively guided.

[0020] 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.

[0021] Beneficial effect: It can ensure that the diversion telescopic component will not separate during expansion and contraction, thereby ensuring the integrity of the diversion telescopic component structure and not affecting the guiding effect of rainwater during operation.

[0022] Furthermore, the sliding baffle is provided with connecting parts at the opposite ends of the surface of the guide telescopic plate, and the connecting parts protrude toward the direction of the guide telescopic plate. A long groove is opened on the connecting part along the extension direction of the intercepting groove, and the long groove extends in the vertical direction. 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.

[0023] Furthermore, the projection area of the sliding baffle in the vertical direction partially overlaps with the projection area of the intercepting groove in the vertical direction.

[0024] 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.

[0025] 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.

[0026] Beneficial effect: Improve the efficiency of intercepting rainwater.

[0027] Furthermore, the interception trough includes a drainage trough and a filter screen. The opposite ends of the drainage trough are connected to the opposite ends of the grille shell. The filter screen is arranged in the drainage trough to filter rainwater entering the drainage trough.

[0028] Beneficial effect: Impurities filtered by the filter will not enter the engine compartment of the car.

[0029] Furthermore, drainage channels are provided 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.

[0030] Beneficial effect: Rainwater filtered by the interception trough is collected and discharged out of the car grille.

[0031] Furthermore, the drainage groove presents a tapered structure with a high middle and low ends along the extending direction of the sliding baffle.

[0032] Beneficial effect: The filtered rainwater can flow autonomously to both sides of the drainage trough and be discharged from the grille shell through the drainage channel.

[0033] Furthermore, vertical sliding grooves are provided on opposite side walls of the grille shell, and opposite end surfaces of the sliding baffle slide along the sliding grooves.

[0034] 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 rainwater interception effect.

[0035] The effective effects of the automobile grille of the present invention are:

[0036] 1. When the automobile grille of the present invention is in use, if the external environment is good and there is no rain, the sliding baffle is driven by the driving assembly to slide upward along the vertical direction of the grille shell, the rotating part rotates relative to the grille shell, and the air 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 sliding baffle of the driving assembly slides downward along the vertical direction of the grille shell, and the rotating part rotates relative to the grille shell under the drive of the sliding baffle, and the air 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 this time, the angle between the air guide telescopic assembly and the air intake port of the grille shell entering the air flow reaches the maximum, so that rainwater entering the grille shell from the air intake port of the grille shell enters the interception groove under the guidance of the air guide telescopic assembly for interception and filtration, effectively preventing the rainwater entering the grille shell from increasing the air humidity of the engine and affecting the engine working efficiency.

[0037] 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 projected area of the sliding baffle in the vertical direction partially overlaps with the projected 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 blocked by the sliding baffle, the rotating baffle and the guide telescopic plate and the inclined guide action of the rotating baffle and the guide telescopic plate, and is guided to the interception groove for interception, thereby preventing the rainwater entering the grille shell from entering the engine compartment of the car, causing the air humidity of the engine to increase and affecting the engine working efficiency.

[0072] Example 1

[0073] Reference Figure 1-Figure 24 The present invention provides an automobile grille, comprising a grille shell 1, a flow guide component, an interception groove 3 and a drive assembly.

[0074] Reference Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 11 、 Figure 12 、 Figure 13The grille housing 1 provides mounting locations for the flow guide components, drive assembly, and components on the interception chute 3. The grille housing 1 is provided with a motor mounting slot 9, a grille baffle 12, a chute 10, a baffle mounting slot 11, and a filter mounting slot 13. The motor mounting slot 9 is located at the top of the grille housing 1 and spaced apart along its length. The grille baffle 12 extends along its length, with its opposite ends fixedly connected to opposite inner walls 24 of the grille housing 1. Multiple grille baffles 12 are provided, spaced apart vertically, with the spacing between adjacent grille baffles 12 being uniform. Grooves 25 are defined on the bottom surface of each grille baffle 12, as well as on the top wall of the grille housing 1. Each groove 25 extends along the length of each grille baffle 12. Multiple chute 10 are provided on the inner walls 24 on either side of the grille housing 1. These chute 10 extend vertically and are spaced apart vertically along the grille housing 1. Multiple baffle fixing slots 11 are defined on both inner walls 24 of the grille housing 1, each located between the air inlet port 4 and the chute 10. Multiple filter fixing slots 13 are provided on the inner wall 24 of the grille housing 1, spaced apart vertically along the inner wall 24 on both sides of the grille housing 1. Drainage channels 20 are defined on opposite sides of the grille housing 1 and extend through the bottom of the grille housing 1.

[0075] Reference Figures 1-10 The air guide component is disposed within the grille housing 1. There are multiple air guide components. A air guide component is provided between each adjacent grille baffle 12. A air guide component is also provided between the grille baffle 12 closest to the top of the grille housing 1 and the top wall of the grille housing 1. A air guide component is also provided between the grille baffle 12 closest to the bottom of the grille housing 1 and the bottom wall of the grille housing 1. The air guide component includes a sliding baffle 5 and an air guide telescopic assembly 6. The sliding baffle 5 extends along the length of the grille housing 1, and opposite ends of the sliding baffle 5 are slidably connected to opposite side walls of the grille housing 1. The number of sliding baffles 5 is the same as the number of chute 10 on one side wall of the grille housing 1, and the number of sliding baffles 5 is also the same as the number of chute 10 on the other side wall of the grille housing 1. One end of the sliding baffle 5 is vertically slidably connected to the chute 10 on one side wall of the grille housing 1, and the other end of the sliding baffle 5 is vertically slidably connected to the chute 10 on the other side wall of the grille housing 1.

[0076] Reference Figure 1-Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figures 16-21The air diversion and telescopic assembly 6 includes a rotating member and an air diversion and telescopic member. The rotating member also extends horizontally along the length of the grille housing 1, such that the extending direction of the rotating member is the same as the extending direction of the sliding baffle 5. Each rotating member is located within a groove 25, and its opposite ends are respectively rotatably connected to the opposite side walls of the grille housing 1. Specifically, 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. The rotating member and the sliding baffle 5 are connected by the air diversion and telescopic member. The air diversion and telescopic member closes the gap between the sliding baffle 5 and the rotating member, and the air diversion and telescopic member can be extended and retracted relative to the rotating member. Specifically, the rotating member is a rotating baffle 7, and the diverter telescopic member is a diverter 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 a rotating part at the 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, which passes through its opposite end faces. A sliding groove 16 communicating with the sliding cavity 15 is provided on one 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 8 facing the sliding baffle is the first side 801 of the guide telescopic plate, and the side of the guide telescopic plate 8 facing away from the sliding baffle is the second side 802 of the guide telescopic 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 slides through 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 escaping from the sliding cavity 15.

[0077] Reference Figures 16-21 Furthermore, the anti-slip portion is connected to the second side 802 of the diversion 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 diversion telescopic part, the "T"-shaped anti-slip structure 17 will not swing, thereby improving the structural stability of the diversion telescopic plate 8 when diverting rainwater, ensuring that the diversion telescopic component 6 will not separate during expansion and contraction, and thus ensuring the integrity of the structure of the diversion telescopic component 6, without affecting the rainwater guiding effect during operation.

[0078] Reference Figure 5-10 、 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 parts protrude toward 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 parts slide up and down along the long grooves 14.

[0079] It should be noted that if Figure 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.

[0080] Figures 1-6 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 The interception groove 3 is provided between the sliding baffle 5 and the air inlet port 4 of the grille shell 1. The interception groove 3 extends along the length direction of the grille shell 1. The number of interception grooves 3 is the same as the number of 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 shell 1. The drainage groove 19 is provided on the upper surface of the grille baffle 12. The drainage groove 19 is also provided on the bottom wall of the grille shell 1. 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 shell 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 shell 1. Furthermore, the drainage groove 19 is provided with connecting holes 21 at both ends extending to the two side walls of the grille shell 1. The drainage groove 19 is connected to the drainage channel 20 through the connecting holes 21, so that 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 car 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 automatically flowing to the drainage channel 20.

[0081] Reference Figures 1-13, the filter 18 is in the shape of a rectangular opening, and both ends of the filter 18 can be 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 can be detachably fixed in the filter fixing groove 13 on one side of the grille shell 1, and the other end of the filter 18 can be 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 trough 19. Of course, there is a distance between the filter 18 and the drainage trough 19 to prevent the bottom surface of the filter 18 from fitting with the bottom surface of the drainage trough 19. The extension direction of the filter 18 is the same as the extension direction of the drainage trough 19. The filter 18 is used to filter rainwater entering the drainage trough 19. In addition, since the filter 18 is embedded in the drainage trough 19, the impurities filtered by the filter 18 will not enter the engine compartment of the car. Reference Figures 1-10 、 Figure 13 The drive assembly is provided on the grille housing 1 and is used to drive the sliding baffle 5 to slide vertically. Specifically, the drive assembly includes a drive motor 22 and a screw rod 23. The drive motor 22 is provided in the motor fixing slot 9 on the grille housing 1. The screw rod 23 is drivingly connected to the output shaft of the drive 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 passed through multiple sliding baffles 5 and is connected with multiple threads. The drive motor 22 drives the screw rod 23 to drive each sliding baffle 5 to move in the vertical direction. The drive assembly can be provided in two or more groups, which can increase the driving force of the sliding baffle 5 and improve the stability of the sliding baffle 5 in the vertical direction.

[0082] 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 in use, 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 to rotate the rotating member relative to the grille shell 1. The diversion telescopic member extends or shortens as the rotating member rotates, thereby adjusting the air intake gap 2 between the interception groove 3 and the sliding baffle 5. Since the outside air of the grille enters the engine compartment of the car from the grille's air inlet port 4 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 volume 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 volume of the car grille.

[0083] 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 blocked by the sliding baffle 5, the rotating baffle 7 and the guide telescopic plate 8 and the inclined guide action of the rotating baffle 7 and the guide telescopic plate 8, and is guided to the interception groove 3 for interception, thereby preventing the rainwater entering the grille shell 1 from entering the engine compartment of the car, causing the air humidity of the engine to increase and affecting the engine working efficiency.

[0084] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 13 When encountering rainy weather, under the drive of the driving assembly, the sliding baffle 5 slides downward along the vertical direction of the grille shell 1. Driven by the sliding baffle 5, the rotating part rotates relative to the grille shell 1, and the guide telescopic part extends as the rotating part rotates, 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 between the guide telescopic assembly 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 assembly 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's working efficiency.

[0085] Reference Figures 1-10 、 Figure 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 into the interception groove 3, further improving the rainwater interception effect.

[0086] Reference Figure 13 、 Figure 22 、 Figure 23 、 Figure 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.

[0087] Reference Figure 13 、 Figure 22 、 Figure 23 、 Figure 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 rainwater interception efficiency. 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.

[0088] The working principle of the automobile grille of the present invention:

[0089] When wading or in rainy weather, the screw 23 rotates under the drive of the drive motor 22, and the multiple groups of sliding baffles 5 connected to the screw 23 slide downward along the slide groove 10 to the maximum limit. The sliding baffle 5 slides downward, and the diversion 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-slip structure 17 of the diversion telescopic plate 8 slides in the sliding cavity 15 of the rotating baffle 7, and the cylindrical sliding part of the diversion telescopic plate 8 slides to the top of the long groove 14. The diversion telescopic plate 8 extends with the rotation of the rotating part. At this time, the diversion 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 car grille is minimized. In this state, when rainwater enters the grille housing 1 through the air inlet port 4, it is guided by the inclination of the guide telescopic plate 8 and the rotating baffle 7, flows along the sliding baffle 5 into the interception groove 3, and is then filtered by the filter screen 18 of the interception groove. The filtered rainwater, due to the tapered effect of the drainage groove 19, flows autonomously into the drainage channels 20 on both sides of the grille and is discharged outside the grille. Thus, it can be seen that the automobile grille of the present invention, while serving to intercept rainwater from entering the engine compartment of the vehicle, does not affect the airflow entering the engine compartment of the vehicle through the air inlet gap 2.

[0090] In rainless weather, when it is necessary to control the air intake of the car 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. Driven by the sliding baffle 5, the guide telescopic assembly 6 rotates the rotating baffle 7 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. The guide telescopic plate 8 is shortened as the rotating part rotates. 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.

[0091] In summary, the air intake volume of the automobile grille is achieved by adjusting the air intake gap 2 between the intercepting 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 volume of the automobile grille.

[0092] 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 diversion 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's working efficiency.

[0093] Example 2

[0094] 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.

[0095] Reference Figure 13 、 Figure 25 、 Figure 26 、 Figure 27 The telescopic diversion assembly 6 of this embodiment utilizes a rolling curtain structure 26. Specifically, the rotating member is a rotating shaft 261, and the telescopic diversion member is a waterproof cloth 262. The waterproof cloth 262 is wound around the rotating member and connected to the sliding baffle 5. During operation, the drive motor 22 drives the screw 23 to rotate, driving 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 member rotates. In this way, driven by the sliding baffle 5, the waterproof cloth 262 forms an angle with the airflow and rainwater entering the grille from the air intake port 4. After entering the grille, the airflow or rainwater is guided by the waterproof cloth 262 and directed into the interception groove 3 for filtration. The airflow then enters the engine compartment through the air intake gap 2. Similarly, this embodiment can also achieve the purpose of guiding incoming airflow and rainwater.

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