Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an active air intake electric grille. Background Technology

[0002] The primary function of a car's grille is to allow air into the engine compartment for cooling the engine, air conditioning system, and other components. Based on function, grilles can be categorized into fixed grilles, active grilles, and closed grilles. Active grilles are electronically controlled and automatically open and close the grille blades based on factors such as vehicle speed and engine temperature. When the engine is cold, the grille closes to allow the engine to warm up faster and reach its optimal operating temperature, saving fuel. At high speeds, the grille closes to reduce air resistance and wind noise, further improving fuel economy. When cooling is needed, the grille automatically opens to introduce more cooling air.

[0003] Currently, most active air intake grilles are designed with a symmetrical layout. The grille blades are connected by gears or connecting rods. Driven by a motor, the grille blades rotate to open and close the grille, thus controlling the amount of airflow entering and exiting.

[0004] However, the current active grille motor is located in the middle of the left and right grilles. The grille blades at the far end have to overcome greater resistance during rotation and are prone to getting stuck. When the blades at the far end get stuck, the entire grille will fail and cannot be opened or closed. Summary of the Invention

[0005] In order to reduce turbulence generation and lower air resistance and noise from active air intake grilles, this application provides an active air intake electric grille.

[0006] The active air intake electric grille provided in this application adopts the following technical solution: An active air intake electric grille includes a grille frame, a drive motor, a connecting rod, and a baffle. The baffle is located inside the grille frame and is rotatably connected to the grille frame. The baffle includes an active baffle and an air intake baffle. The baffle is provided with a mounting shaft, which is used to install the baffle on the grille frame. A drive shaft is fixedly connected to the mounting shaft of the active baffle, and the drive shaft passes through the grid frame and is fixedly connected to the output end of the drive motor. Multiple drive motors are provided, and the drive motors are fixedly connected to the grid frame. The drive motors are used to control the rotation of the active baffle. Multiple connecting rods are provided, each connecting rod is rotatably connected to an active baffle, and each connecting rod is also fixedly connected to at least one of the intake baffles, so that the rotation of the active baffle can synchronously drive the intake baffle to rotate through the connecting rods fixed to it.

[0007] By adopting the above technical solution, multiple drive motors are used to drive the baffles, which avoids excessive resistance caused by the baffles being too far away from the drive motors. This reduces the torque required for the rotation of the baffles. Furthermore, with multiple motors driving the operation, the grille can still function normally even if one set of baffles is damaged.

[0008] Preferably, an air guide block is fixedly provided on the grille frame, and an opening is provided on the baffle. When the baffle is in the closed state, the air guide block is located at the opening.

[0009] By adopting the above technical solution, when the baffle is open, the airflow is combed and diverted as it passes through the air guide block, allowing it to pass through the grille more smoothly, effectively reducing air resistance and energy consumption. When the baffle is closed, the air guide block is located at the opening of the baffle, preventing airflow from passing through the grille.

[0010] Preferably, the grid frame is provided with a mounting hole that mates with a mounting shaft, and the mounting shaft is rotatably disposed within the mounting hole.

[0011] By adopting the above technical solution, the baffle and the grid frame are rotatably connected by using the mounting shaft and mounting hole.

[0012] Preferably, a connecting block is fixedly provided on the baffle, and a connecting shaft is provided on the connecting block; a connecting hole is provided on the connecting rod to cooperate with the connecting shaft, and the connecting shaft passes through the connecting hole.

[0013] By adopting the above technical solution, a connecting block is set on the baffle, and a connecting shaft is set on the connecting block. The connecting shaft cooperates with the connecting hole on the connecting rod to realize the drive motor to drive the intake baffle to rotate.

[0014] Preferably, the active baffle is divided into a first part and a second part. The first part of each active baffle is connected to the drive motor via a mounting shaft, and the second part of the active baffle is connected to the grid frame. The first part and the second part are inserted and fixed together, and the strength of the material of the first part is greater than that of the material of the second part. The active baffle is provided with a first part of different area to distinguish the position of each active baffle.

[0015] By adopting the above technical solution, the first part uses high-strength materials to enable the active baffle to withstand high-strength torque, while the second part uses general materials to reduce costs. The combination of the two ensures the strength of the active baffle while reducing costs.

[0016] Preferably, the grid frame is arc-shaped; the angle between the drive shaft of the active baffle and the baffle body gradually increases from the center of the grid to both sides.

[0017] By adopting the above technical solution, the angle between the drive shaft of the active baffle and the baffle body increases as the curvature of the grid frame increases, so as to reduce the gap between the grids.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. The grid blades are segmented and driven by multiple drive motors, which reduces the distance between the baffle and the drive motor, reduces the resistance of the baffle, and at the same time, the segmented design ensures that the grid can be used normally even if one section of the baffle is unusable. 2. The active baffle is designed in two parts. The first part uses high-performance materials, while the second part uses general materials, which enables the active baffle to withstand high-intensity torque while controlling manufacturing costs.

[0020] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0021] The applicant discovered that the existing active grille shutters, driven by a single motor in the center, require significant resistance to rotate when the baffles located far from the motor are turned, making them prone to jamming. When a single baffle jams, the entire grille cannot rotate, and the grille cannot be opened or closed, affecting air intake.

[0022] To address the aforementioned issues, this application provides an active air intake electric grille that employs multiple drive motors to drive the baffles in segments. Multiple drive motors are installed on the baffles on both the left and right sides, reducing the resistance that the baffles need to overcome to rotate and making them less prone to jamming. Furthermore, the segmented design ensures that even if one segment of the baffles fails, the remaining baffles in the affected area can still function.

[0023] This application discloses an active air intake electric grille, see reference. Figure 1 and Figure 2 The active air intake electric grille includes a grille frame 1, a drive motor 4, a connecting rod 3, and a baffle 2.

[0024] The active air intake electric grille is divided into two parts, left and right, which are arranged symmetrically.

[0025] The grille frame 1 is arc-shaped, and its drive motor 4 side is wider than the non-drive motor 4 side to better fit the front contour of the car and accommodate the drive components. A motor mounting base 101 is integrally formed on the grille frame 1 for mounting the drive motor 4, which can be fixed with bolts. Threaded holes 102 are provided on the periphery of the grille frame 1 for bolting the entire grille to the vehicle body. To enhance connection stability, a fixing block 103 is provided on the inner side of the grille frame 1 facing the car. Fixing rods 104 are provided on the fixing block 103 and on the drive motor 4 side of the grille frame 1 near the car, providing auxiliary reinforcement to the car body. Furthermore, mounting holes 106 for supporting the rotation of the baffle 2 are provided on the upper and lower inner walls of the grille frame 1. An air guide block 105 is fixed on the side near the drive motor 4 to streamline and divert airflow, allowing it to pass through the grille more smoothly and effectively reducing air resistance.

[0026] Multiple drive motors 4 are provided. Specifically, each side of the grille is provided with 3 drive motors 4. The drive motors 4 are mounted on the motor mounting base 101. The drive motors 4 are all controlled by the vehicle host and can receive signals from the vehicle host to control the opening and closing of the baffle 2. The movement of the 6 drive motors 4 on the left and right sides is completely synchronized.

[0027] For details, please refer to Figure 3 The baffle 2 is divided into an active baffle 201 and an intake baffle 202. The active baffle 201 is connected to the drive motor 4, while the intake baffle 202 is not connected to the drive motor 4. Both ends of the baffle 2 are provided with mounting shafts 203, which are rotatably mounted in mounting holes 106 on the grille frame 1, allowing the baffle 2 to rotate around the mounting shafts 203. A connecting block 205 is also fixedly connected to the end of the baffle 2 away from the drive motor 4. Each connecting block 205 is provided with a connecting shaft 206, which is used to fixally connect to the connecting rod 3. An opening 207 is provided on the baffle 2. When the baffle 2 is in the closed state, the opening 207 matches the contour of the air guide block 105. The opposite side of the rotating shaft of the baffle 2 is designed as an inclined plane 208. The inclined plane 208 design reduces the radius required for the rotation of the baffle 2, thus reducing the size of the grille.

[0028] For details, please refer to Figure 4A drive shaft 204 is fixedly connected to the mounting shaft 203 of the active baffle 201. The drive shaft 204 passes through the grille frame 1 and is connected to the output end of the drive motor 4. The drive shaft 204 and the main body of the baffle 2 have an angle, which gradually increases from the center of the grille to both sides.

[0029] The active baffle 201 is divided into a first part 201a and a second part 201b. The first part 201a is connected to the output terminal of the drive motor 4 and is made of a high-strength material, such as iron. The second part 201b is made of engineering plastics, which are weaker than the first part 201a. The first part 201a and the second part 201b are fixedly connected by a plug-in connection. This structural design enables the active baffle 201 to have high strength and high reliability in key stress areas, while significantly reducing the overall weight and material cost, and avoiding the problems of easy corrosion and heavy weight of all-metal structures. The area of ​​the first part 201a of different active baffles 201 varies to distinguish the position of the active baffle 201. The area of ​​the first part 201a of the active baffle 201 in the middle of the single-sided grille is the smallest, the area of ​​the first part 201a of the active baffle 201 at the edge of the grille is the second largest, and the area of ​​the first part 201a near the axis of symmetry of the grille is the largest.

[0030] The connecting rod 3 is a rigid rod-shaped component. The connecting rod 3 is provided with a connecting hole 301 that mates with the connecting shaft 206. The connecting shaft 206 passes through the connecting hole 301 and is rotatably connected to the connecting rod 3. Under the action of the active baffle 201, the movement of the connecting rod 3 drives the intake baffle 202 to open and close.

[0031] The principle of this embodiment is as follows: Under the control of the vehicle-mounted host, multiple drive motors 4 rotate synchronously, and the rotation of the drive motors 4 drives the active baffle 201 to rotate along the mounting shaft 203. When the active baffle 201 rotates, it pushes or pulls the connecting rod 3 through the connecting block 205 and the connecting shaft 206. The connecting rod 3 then transmits the motion to the intake baffle 202 that is hinged to it, thereby driving all intake baffles 202 to open and close synchronously, realizing the control of the airflow entering the electric intake grille. By using multiple drive motors 4 to drive in a distributed manner, the distance between the baffle 2 and the drive motor 4 is small, and the resistance to be overcome during rotation is small. At the same time, the segmented design means that even if a single baffle 2 is damaged, it will not affect the normal use of other baffles 2.

[0032] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
