[0002] The car radiator grille is located at the front end of the car engine radiator. The grille is a window that transports air from the outside to the inside. The purpose is to send air into the engine compartment to cool the high-temperature components in the engine compartment with the outside air, and at the same time intercept external debris to prevent it from entering the engine compartment. However, when the engine temperature in the engine compartment is low, when the grille is in the open state, it will reduce the engine's heating rate, resulting in the engine being unable to reach the optimal operating temperature in a short time. In addition, a normally open grille will also increase wind resistance when driving at high speeds. Utility Model Content

[0005] Furthermore, the closure assembly includes mounting grooves opened on both sides of the multiple air inlets, blades arranged inside the air inlets, and rotating shafts arranged on both sides of the blades. The rotating shafts are rotatably connected to the inner walls on both sides of the air inlets and extend through the air inlets to the inside of the mounting grooves. The follower gear is arranged on the rotating shaft inside the mounting groove on one side.

[0006] Furthermore, the driving assembly includes a first supporting end, an adjusting screw, a motor, a driving member, and a rack. The first supporting end is symmetrically arranged on two mounting brackets, the adjusting screw is rotatably arranged between the two first supporting ends, the motor is arranged on the first supporting end at one end, and the driving end is connected to the adjusting screw, the driving member is threadedly connected to the adjusting screw, the rack is arranged on the front end surface of the driving member, and the rack is meshed with the follower gear.

[0007] Furthermore, the driving assembly also includes a second supporting end and a sliding rod, the second supporting end is symmetrically arranged on the mounting bracket on one side of the first supporting end, the sliding rod is arranged between the two second supporting ends, and one side of the driving member is slidably connected to the sliding rod.

[0008] Furthermore, the grille body is provided with mounting parts at the upper and lower ends, and the mounting parts are provided with mounting holes.

[0009] The beneficial effects of the utility model are:

[0010] The utility model cooperates with a closing component, a follower gear, a mounting bracket, a support column, a cooling fan, and a driving component. When the engine temperature is low, the driving component drives the follower gear to work, driving the closing component to close the air inlet of the grille body, so that the engine can reach the optimal operating temperature in a shorter time, and reduce wind resistance when driving at high speeds, thereby improving fuel economy. The driving component drives the follower gear to rotate, so that the closing component rotates to different opening and closing angles, thereby improving the air intake efficiency and heat dissipation efficiency of the automobile. The cooling fan can increase the air intake and heat dissipation effects when driving at low speeds, and when the vehicle stops moving, it continues to dissipate heat in the engine compartment, thereby reducing aging of internal components due to continuous high temperature.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] Reference Figure 1-5 As shown, a durable radiator grille for an automobile comprises a grille body 1 and air inlets 2 which are arranged on the grille body 1 at intervals from top to bottom. A plurality of air inlets 2 are adjustable inside with closing components 3, and a follower gear 4 is arranged on the closing component 3. The closing component 3 comprises mounting grooves 301 arranged on both sides of the plurality of air inlets 2, blades 302 arranged inside the air inlet 2, and rotating shafts 303 arranged on both sides of the blades 302. The rotating shafts 303 are rotatably connected to the inner walls on both sides of the air inlet 2, and extend through the air inlet 2 to the inside of the mounting groove 301. The follower gear 4 is arranged on the rotating shaft 303 inside the mounting groove 301 on one side, and the outer surface of the follower gear 4 extends to the outside of the mounting groove. The rotation of the follower gear 4 drives the rotating shaft 303 and the blades 302 to rotate, so that the blades 302 rotate to different opening and closing angles, so that the air inlet 2 is in an open or closed state.

[0020] Behind the grille body 1, horizontally arranged mounting brackets 5 are provided above and below the multiple air inlets 2. Support columns 6 are provided between the two sides of the front end surface of the mounting bracket 5 and the rear end surface of the grille body 1. The support columns 6 leave a spacing space between the mounting bracket 5 and the grille body 1. A cooling fan 7 is provided on the rear end surface of the mounting bracket 5 and is located on the same central axis as the air inlet 2. The four corners of the outer shell of the cooling fan 7 are fixed to the two mounting brackets 5 by bolts. The cooling fan 7 can increase the air intake and heat dissipation effect when driving at low speed, and continue to dissipate heat to the cabin when the vehicle stops moving, thereby reducing the aging of internal components due to continuous high temperature.

[0021] A driving assembly connected to the follower gear 4 is provided on one side of the front end surface of the mounting bracket 5, and the driving assembly drives the closing assembly to work, so that the air inlet 2 is in an open or closed state. The driving assembly includes a first support end 801, an adjusting screw 802, a motor 803, a driving member 804, and a rack 805. The first support end 801 is symmetrically arranged on the two mounting brackets 5, and the adjusting screw 802 is rotatably arranged between the two first support ends 801. The motor 803 is arranged on the first support end 801 at one end, and the driving end is connected to the adjusting screw 802. The motor 803 is connected to the control of the vehicle. The device is electrically connected, and the vehicle controller calculates and controls the operation of the motor 803 according to the engine operation status and driving speed of the vehicle. The driving member 804 is threadedly connected to the adjusting screw 802, and the rack 805 is arranged on the front end surface of the driving member 804, and the rack 805 is meshed with the follower gear 4. The driving component and the cooling fan 7 are installed on the mounting bracket 5 together, which saves more installation space, and only the mounting bracket 5 needs to be disassembled for maintenance and replacement at the later stage, which has better practicality. The driving component cooperates with the thread of the driving member 804 through the adjusting screw 802, and has a simple structure and better durability.

[0022] The driving assembly also includes a second supporting end 806 and a sliding rod 807. The second supporting end 806 is symmetrically arranged on the mounting bracket 5 on one side of the first supporting end 801. The sliding rod 807 is arranged between the two second supporting ends 806. One side of the driving member 804 is slidably connected to the sliding rod 807. The motor 803 drives the adjusting screw 802 to rotate, drives the driving member 804 to reciprocate up and down along the sliding rod 807 and the adjusting screw 802, and drives the rack 805 to move up and down. Since the rack is meshed with the follower gear 4, the follower gear 4 is driven to rotate, driving the blade 302 to rotate to different opening and closing angles, so as to make the car's air intake efficiency and heat dissipation efficiency better. When the engine temperature is low, the driving assembly drives the follower gear 4 to work, driving the closing assembly to close the air inlet 2 of the grille body 1, so that the engine can reach the optimal operating temperature in a shorter time, and reduce wind resistance when driving at high speed, thereby improving fuel economy.

[0023] Mounting parts 9 are provided at the upper and lower ends of the grille body 1 . Mounting holes 10 are provided on the mounting parts 9 . The mounting parts 9 are connected to the front bumper of the vehicle through the mounting holes 10 .
