Description

Technical Field

[0001] This utility model belongs to the field of automotive grille technology, and in particular relates to an adjustable-angle ventilation mechanism for automotive grilles. Background Technology

[0002] According to the published patent CN219706680U, a car air intake grille opening adjustment structure includes an outer grille, a movable grille fixedly installed on one side of the outer grille, the outer grille including a first frame, and several grille plates vertically fixedly installed inside the first frame. The movable grille includes a second frame, and an air intake plate fixedly installed inside the second frame near the outer grille. Several strip-shaped first air intake holes are opened on the surface of the air intake plate. This realizes the opening adjustment of the air intake grille and reduces the impact on the grille blades when the car is driving at high speed. However, it still has the following shortcomings:

[0003] While the aforementioned equipment can adjust the ventilation volume of the car's grille, it is not convenient to adjust the ventilation angle. This may cause excessive cold air to rush in during cold starts, delaying engine warm-up and increasing wear. At high speeds, it cannot adapt to the airflow direction, resulting in wind resistance, wasted energy, and reduced heat dissipation efficiency. Therefore, we propose an adjustable-angle ventilation mechanism for the car's grille. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable-angle ventilation mechanism for automotive grilles. Through the adjustment mechanism and the installation mechanism, it solves the problems of the above-mentioned devices, which, although able to adjust the ventilation volume of the automotive grille, are not convenient to adjust the ventilation angle. This may cause excessive cold air to rush in during cold starts of the vehicle, delaying engine warm-up, increasing wear, and failing to adapt to airflow direction during high-speed driving, resulting in wind resistance, wasted energy, and affecting heat dissipation efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an adjustable-angle ventilation mechanism for a car grille, including a car grille, with a frame slidably connected to the outer wall of the car grille, and an adjustment mechanism provided on the inner wall of the car grille;

[0007] The adjustment mechanism includes several rotating shafts, each with a baffle fixedly connected to its outer wall. A connecting rod is fixedly connected to the outer wall of each rotating shaft at the end furthest from the baffle. A second rotating shaft is rotatably connected to the inner wall of the connecting rod at the end furthest from the rotating shaft. A second connecting rod is rotatably connected to the outer wall of the second rotating shaft. A limiting shaft is fixedly connected to the central axis of the top outer wall of the second connecting rod. A third connecting rod is rotatably connected to the outer wall of the limiting shaft. A second limiting shaft is rotatably connected to the inner wall of the third connecting rod at the end furthest from the limiting shaft. A connecting block is fixedly connected to the outer wall of the second limiting shaft. An electric telescopic rod is fixedly connected to the inner wall of the car grille at the end closest to the connecting block. An installation mechanism is provided on the outer wall of the car grille.

[0008] Furthermore, the outer walls of several of the rotating shafts are rotatably connected to the inner wall of the car grille, and the bottom output end of the electric telescopic rod is fixedly connected to the outer wall of the connecting block.

[0009] Furthermore, the mounting mechanism includes a plurality of mounting blocks, the outer walls of which are fixedly connected to the outer wall of the vehicle's grille.

[0010] Furthermore, the inner wall of the frame near the mounting block is provided with several limiting grooves, and the inner walls of the limiting grooves are slidably connected to mounting plates.

[0011] Furthermore, the inner wall of the mounting plate is provided with a plurality of limiting grooves, and the inner wall of each limiting groove is slidably connected with a locking block.

[0012] Furthermore, the inner wall of the end of the card block away from the mounting plate is rotatably connected to several limiting shafts three, and the outer walls of the several limiting shafts three are all fixedly connected to connecting rods four.

[0013] Furthermore, a limiting shaft four is fixedly connected to the inner wall of one end of each of the connecting rods away from the locking block, and a threaded rod sleeve is rotatably connected to the outer wall of the limiting shaft four.

[0014] Furthermore, the inner wall of the threaded rod sleeve is threadedly connected to a threaded rod, and the outer wall of the threaded rod is rotatably connected to the inner wall of the mounting plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a baffle on the rotating shaft, allows for remote activation of an electric telescopic rod to adjust the ventilation angle or volume of the car's grille when needed. The extension of the electric telescopic rod pushes a connecting block, causing the second limiting shaft to move away from the electric telescopic rod. This movement of the second limiting shaft then pushes a connecting rod, causing the third limiting shaft to move away from the electric telescopic rod. This facilitates easy adjustment of the ventilation volume and angle of the car's grille. The flexible blade adjustment structure and convenient operation design allow users to easily adjust the grille's ventilation volume and angle according to actual needs without complex operations, significantly improving usability and the mechanism's practicality.

[0017] 2. This utility model, by setting a locking block in the limiting slide groove, allows for easy removal of the car grille from the car frame during use. Simply rotate the threaded rod, which moves the threaded rod sleeve closer to the limiting slide groove. As the threaded rod sleeve approaches the limiting slide groove, it simultaneously pulls multiple connecting rods four through the limiting shaft three, causing them to gradually rotate upwards around the limiting shaft three. Because the limiting slide groove restricts the movement trajectory of the locking block, it facilitates the user's direct installation of the car grille onto the car frame. Furthermore, the installation and disassembly of the device are simple and convenient, requiring no additional workpieces, making it easy for the user to operate.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is an adjustable angle ventilation mechanism for a car grille, including a car grille 1, a frame 101 slidably connected to the outer wall of the car grille 1, and an adjustment mechanism 2 provided on the inner wall of the car grille 1. The frame 101 facilitates the user to install the car grille 1 as a whole on the car, and at the same time prevents the car grille 1 from becoming loose.

[0029] The adjusting mechanism 2 includes several rotating shafts 201. Each rotating shaft 201 has a baffle 202 fixedly connected to its outer wall. A connecting rod 203 is fixedly connected to the outer wall of each rotating shaft 201 at the end away from the baffle 202. A second rotating shaft 204 is rotatably connected to the inner wall of the connecting rod 203 at the end away from the rotating shaft 201. The connecting rod 203 can limit the position of the second rotating shaft 204 to prevent displacement. Simultaneously, when the second rotating shaft 204 moves, it can drive the connecting rod 203 to move, causing the rotating shaft 201 to rotate. A second connecting rod 205 is rotatably connected to the outer wall of the second rotating shaft 204. A limit shaft 206 is fixedly connected to the central axis of the top outer wall of the second connecting rod 205. A third connecting rod 207 is rotatably connected to the outer wall of the limit shaft 206. The inner wall of the third link 207 away from the limiting shaft 206 is rotatably connected to the second limiting shaft 208. The third link 207 can fix the position of the second limiting shaft 208 to prevent it from falling off. At the same time, when the second limiting shaft 208 moves, it can push the third link 207 to move, which in turn can make the limiting shaft 206 move. The outer wall of the second limiting shaft 208 is fixedly connected to the connecting block 209. The inner wall of the car grille 1 near the connecting block 209 is fixedly connected to the electric telescopic rod 210. The outer wall of the car grille 1 is provided with the mounting mechanism 3. When the user remotely starts the electric telescopic rod 210 through the external controller, the electric telescopic rod 210 extends and can push the connecting block 209 to move, which in turn can drive the second limiting shaft 208 to move.

[0030] The outer walls of several rotating shafts 201 are rotatably connected to the inner wall of the car grille 1. The bottom output end of the electric telescopic rod 210 is fixedly connected to the outer wall of the connecting block 209. The mounting mechanism 3 includes several mounting blocks 301, the outer walls of which are fixedly connected to the outer wall of the car grille 1. The mounting blocks 301 facilitate the user to directly mount the car grille 1 onto the frame 101. Furthermore, since the mounting blocks 301 have built-in mounting holes, it is convenient for the user to attach the threaded rod 3. 10 passes through the mounting block 301. The inner wall of the frame 101 near the mounting block 301 is provided with several limiting grooves 302. The inner walls of the several limiting grooves 302 are slidably connected to the mounting plate 303. The inner wall of the mounting plate 303 is provided with several limiting slide grooves 304. The inner walls of the several limiting slide grooves 304 are slidably connected to the locking block 305. The limiting slide groove 304 can limit the movement trajectory of the locking block 305, so that it can only move in a straight line along the direction of the limiting slide groove 304 within the limiting slide groove 304.

[0031] A plurality of limiting shafts 306 are rotatably connected to the inner wall of the end of the locking block 305 away from the mounting plate 303. Each of the limiting shafts 306 has a connecting rod 307 fixedly connected to its outer wall. Each of the connecting rods 307 has a limiting shaft 308 fixedly connected to its inner wall at the end away from the locking block 305. The limiting shafts 308 can limit the position of the connecting rods 307, preventing them from falling off. Simultaneously, when the threaded sleeve 309 drives the limiting shafts 308 to move, the limiting shafts 308 can pull the connecting rods 307 to move. The outer wall of the fourth plate 308 is rotatably connected to a threaded rod sleeve 309, and the inner wall of the threaded rod sleeve 309 is threadedly connected to a threaded rod 310. The outer wall of the threaded rod 310 is rotatably connected to the inner wall of the mounting plate 303. Since the threaded grooves between the threaded rod 310 and the threaded rod sleeve 309 are engaged with each other, the threaded rod sleeve 309 can be driven to rise or fall when the threaded rod 310 is rotated. At the same time, when the rotation of the threaded rod 310 is stopped, the threaded rod sleeve 309 will lock itself due to the threaded connection to prevent the threaded rod sleeve 309 from being displaced.

[0032] One specific application of this embodiment is:

[0033] When staff need to use the equipment, if they need to adjust the ventilation angle or ventilation volume of the car's grille 1, they can remotely activate the electric telescopic rod 210 via an external setting. The extension of the electric telescopic rod 210 pushes the connecting block 209, causing the limiting shaft 208 to move away from the electric telescopic rod 210. When the limiting shaft 208 moves, it pushes the connecting rod 207, causing the limiting shaft 206 to move away from the electric telescopic rod 210. The movement of the limiting shaft 206 then causes the connecting rod 205 to move away from the electric telescopic rod 210. When one side of the telescopic rod 210 moves, multiple rotating shafts 204 are installed inside the connecting rod 205. Therefore, when the connecting rod 205 moves, it simultaneously drives multiple rotating shafts 204 to move. When the rotating shafts 204 move, they drive the connecting rod 203 to rotate around the rotating shaft 201, gradually moving it away from the electric telescopic rod 210. When the rotating shaft 201 rotates, it drives the baffle 202 to rotate. By adjusting the gap and angle between the baffles 202, the ventilation angle or ventilation volume of the car grille 1 can be controlled. The combination of 8, the limiting shaft 206, and the connecting rod 207 prevents the connecting rod 205 from jamming during movement. When it is necessary to remove the car grille 1 from the car frame 101, simply rotate the threaded rod 310. The rotation of the threaded rod 310 will cause the threaded rod sleeve 309 to move closer to the limiting groove 304. As the threaded rod sleeve 309 moves closer to the limiting groove 304, it will simultaneously pull multiple connecting rods 307 via the limiting shaft 308, causing them to gradually rotate upwards around the limiting shaft 306. The movement trajectory of the locking block 305 is limited by the limiting slide groove 304. Therefore, when the connecting rod 4 307 moves, it will gradually pull the limiting shaft 306, causing the locking block 305 to slide in the limiting slide groove 304, so that the locking block 305 gradually gathers inward. When the bottom end of the locking block 305 no longer clamps the mounting block 301, the mounting plate 303 together with the threaded rod 310 can be directly removed from the limiting groove 302. Then the mounting block 301 can be removed from the frame 101, and the car grille 1 can be separated from the frame 101.
