Description

Technical Field

[0001] The utility model relates to the technical field of headlamp angle adjustment, and specifically relates to an actuator module with an angle adjustment function. Background Technique

[0002] With the rapid development of automotive intelligence, customers' requirements for headlamps are getting higher and higher, especially for low beams. Since low beams are mandatory lighting fixtures at night, with the advancement of intelligence, the adaptive headlamp AFS system (curve assist lighting system) has emerged. When a vehicle turns at night, because ordinary headlamps cannot adjust the lighting angle and can only maintain a fixed lighting range, there are often "blind spots" inside the curve, which seriously threatens the safety of the driver. The follow-up steering headlamp can continuously and dynamically adjust the headlamp according to the angle of the steering wheel, the deflection rate of the vehicle, and the driving speed to adapt to the current steering angle, making the direction of the light consistent with the current driving direction of the vehicle, providing all-round safe lighting for the driver, and thus effectively improving the safety of night driving. The existing curve assist lighting system uses a complex horizontal dimming actuator, with complex technology, high cost, and poor reliability. This aspect uses a simple mechanical mechanism to greatly reduce the cost and the weight of the entire lamp while ensuring the use effect. Summary of the Invention

[0003] The purpose of the utility model is to provide an actuator module with an angle adjustment function to solve the problems raised in the above background technique.

[0004] To solve the above technical problems, the utility model provides the following technical solutions:

[0005] The actuator module includes a stepper motor, a dimming bracket, a lens bracket, a dimming ball head seat, a dimming rod, a Hall sensor, a magnet, and a connecting shaft. The stepper motor and the dimming bracket are connected by screws. One end of the lens bracket passes through the dimming bracket. One end of the connecting shaft is fixedly connected to the dimming bracket, and the other end of the connecting shaft is fixedly connected to the lens bracket. The dimming bracket and the lens bracket are rotationally connected through the connecting shaft. One end of the dimming ball head seat is clamped with the stepper motor, and the other end of the dimming ball head seat is fixedly connected to the dimming rod. The dimming rod passes through the through-hole end of the dimming ball head seat. One end of the dimming rod is connected to one end of the lens bracket. The Hall sensor and the dimming bracket are connected by a buckle. The magnet and the lens bracket are connected by screws. The Hall sensor and the magnet are located between the dimming bracket and the lens bracket. The Hall sensor faces the magnet, and there is a gap between the Hall sensor and the magnet.

[0006] The dimming bracket serves as the installation base. The stepper motor pushes the dimming ball head seat, and the dimming ball head seat drives the displacement of the dimming rod. Since one end of the dimming rod is connected to the lens bracket, and the dimming bracket and the lens bracket are rotationally connected through a link shaft, the dimming rod drives the lens bracket to rotate around the shaft, resulting in changes in the distance and angle between the magnet connected to the lens bracket and the Hall sensor clamped on the dimming bracket. The Hall sensor senses the change in the magnetic pole signal, forms an electrical signal feedback, and then controls the telescopic movement of the stepper motor, thereby controlling the angle required for the vehicle lamp illumination.

[0007] Further, one end of the dimming ball head seat is provided with a through hole, the dimming rod passes through the through hole at one end of the dimming ball head seat, the other end of the dimming ball head seat is spherical, a spherical depression is provided on the spherical end of the dimming ball head seat, and one end of the stepper motor is clamped with the spherical end of the dimming ball head seat.

[0008] One end of the dimming ball head seat is provided with a through hole, one end is spherical and provided with a spherical depression, which provides an angle for the rotation of the dimming rod, so that the lens bracket drives the movement of the magnet, changes the magnetic pole signal sensed by the Hall sensor, and makes a feedback.

[0009] Further, a limiting column is provided on the lens bracket, and the limiting column passes through one end of the magnet.

[0010] Setting the limiting column can better locate the installation position of the magnet on the lens bracket, which is convenient for installation.

[0011] Further, a motor limiting structure is provided on the dimming bracket, and the stepper motor passes through the motor limiting structure.

[0012] Setting the motor limiting structure can quickly locate the installation position of the stepper motor on the dimming bracket, which is convenient for installation.

[0013] Further, a sensor limiting structure is provided on the dimming bracket, and the Hall sensor is inserted into the sensor limiting structure.

[0014] Setting the sensor limiting structure can quickly locate and install the Hall sensor, which is convenient for installation, and can determine the positional relationship between the Hall sensor and the magnet in cooperation with the limiting column on the lens bracket, ensuring the normal operation of the actuator module.

[0015] Further, one end of the telescopic rod of the stepper motor is spherical, and the spherical end of the telescopic rod of the stepper motor passes through the motor limiting structure and is clamped with the ball head end of the dimming ball head seat.

[0016] One end of the telescopic rod of the stepper motor is spherical and is clamped with the ball head end of the dimming ball head seat, forming a spherical hinge, which can provide an angle for the rotation of the lens bracket.

[0017] The length of the link shaft is 20 mm to 30 mm.

[0018] The length of the link shaft is 20 mm to 30 mm. The sizes of different link shafts match various horizontal dimming angles required by customers, meeting the needs of more customers.

[0019] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows: When the present utility model is working, the stepping motor pushes the dimming ball head seat, and the dimming ball head seat drives the displacement of the dimming rod. Since one end of the dimming rod is connected to the lens bracket, and the dimming bracket and the lens bracket are rotationally connected through the link shaft, the dimming rod drives the lens bracket to rotate around the axis, resulting in changes in the distance and angle between the magnet connected to the lens bracket and the Hall sensor clamped on the dimming bracket. The Hall sensor senses the change in the magnetic pole signal, forms an electrical signal feedback, and then controls the telescopic movement of the stepping motor, thereby controlling the angle required for the vehicle lamp illumination.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] The technical solution provided by the utility model is as follows:

[0029] As Figure 1 shown, the actuator module includes a stepper motor 1, a dimming bracket 2, a lens bracket 3, a dimming ball head seat 4, a dimming rod 5, a Hall sensor 6, a magnet 7 and a linking shaft 8. The stepper motor 1 and the dimming bracket 2 are connected by screws. One end of the lens bracket 3 passes through the dimming bracket 2. One end of the linking shaft 8 is fixedly connected to the dimming bracket 2, and the other end of the linking shaft 8 is fixedly connected to the lens bracket 3. The dimming bracket 2 and the lens bracket 3 are rotationally connected by the linking shaft 8. One end of the dimming ball head seat 4 is snap-connected to the stepper motor 1, and the other end of the dimming ball head seat 4 is fixedly connected to the dimming rod 5. The dimming rod 5 passes through the through-hole end of the dimming ball head seat 4. One end of the dimming rod 5 is connected to one end of the lens bracket 3. The Hall sensor 6 and the dimming bracket 2 are snap-connected. The magnet 7 and the lens bracket 3 are connected by screws. The Hall sensor 6 and the magnet 7 are located between the dimming bracket 2 and the lens bracket 3. The Hall sensor 6 faces the magnet 7, and there is a gap between the Hall sensor 6 and the magnet 7.

[0030] The dimming bracket 2 serves as the installation base. The stepper motor 1 pushes the dimming ball head seat 4, and the dimming ball head seat 4 drives the dimming rod 5 to displace. Since one end of the dimming rod 5 is connected to the lens bracket 3 and the dimming bracket 2 and the lens bracket 3 are rotationally connected by the linking shaft 8, the dimming rod 5 drives the lens bracket 3 to rotate around the axis, resulting in changes in the distance and angle between the magnet 7 connected to the lens bracket 3 and the Hall sensor 6 snap-connected to the dimming bracket 2. The Hall sensor 6 senses the change in the magnetic pole signal, forms an electrical signal feedback, and then controls the expansion and contraction of the stepper motor 1, thereby controlling the angle required for vehicle lighting.

[0031] As Figure 4 shown, one end of the dimming ball head seat 4 is provided with a through-hole. The dimming rod 5 passes through the through-hole at one end of the dimming ball head seat 4. The other end of the dimming ball head seat 4 is spherical, and a spherical depression is provided on the spherical end of the dimming ball head seat 4. One end of the stepper motor 1 is snap-connected to the spherical end of the dimming ball head seat 4.

[0032] One end of the dimming ball head seat 4 is provided with a through-hole, one end is spherical and provided with a spherical depression, which provides an angle for the rotation of the dimming rod 5, so that the lens bracket 3 drives the movement of the magnet 7, changes the magnetic pole signal sensed by the Hall sensor 6, and makes a feedback.

[0033] As Figure 3 shown, a limiting column 31 is provided on the lens bracket 3, and the limiting column 31 passes through one end of the magnet 7.

[0034] Setting the limit post 31 can better locate the installation position of the magnet 7 on the lens bracket 3, facilitating the installation.

[0035] As Figure 2 shown, a motor limit structure 22 is provided on the dimming bracket 2, and the stepper motor 1 passes through the motor limit structure 22.

[0036] Setting the motor limit structure 22 can quickly locate the installation position of the stepper motor 1 on the dimming bracket 2, facilitating the installation.

[0037] As Figure 2 shown, a sensor limit structure 21 is provided on the dimming bracket 2, and the Hall sensor 6 is inserted into the sensor limit structure 21.

[0038] Setting the sensor limit structure 21 can quickly locate and install the Hall sensor 6, facilitating the installation, and in cooperation with the limit post 31 on the lens bracket 3, it can determine the positional relationship between the Hall sensor 6 and the magnet 7, ensuring the normal operation of the actuator module.

[0039] As Figure 4 shown, one end of the telescopic rod of the stepper motor 1 is spherical, and the spherical end of the telescopic rod of the stepper motor 1 passes through the motor limit structure 22 and is clamped with the ball head end of the dimming ball head seat 4.

[0040] One end of the telescopic rod of the stepper motor 1 is spherical and is clamped with the ball head end of the dimming ball head seat 4, forming a spherical hinge, which can provide an angle for the rotation of the lens bracket 3.

[0041] The length of the link shaft 8 is 20 mm to 30 mm.

[0042] The length of the link shaft 8 is 20 mm to 30 mm. Different sizes of the link shaft 8 match various horizontal dimming angles required by customers, meeting the needs of more customers.

[0043] The working principle of the present utility model: When the present utility model is working, the stepper motor 1 pushes the dimming ball head seat 4, and the dimming ball head seat 4 drives the dimming rod 5 to displace. Since one end of the dimming rod 5 is connected to the lens bracket 3, and the dimming bracket 2 and the lens bracket 3 are rotationally connected through the link shaft 8, the dimming rod 5 drives the lens bracket 3 to rotate around the axis, resulting in changes in the distance and angle between the magnet 7 connected to the lens bracket 3 and the Hall sensor 6 clamped on the dimming bracket 2. The Hall sensor 6 senses the change in the magnetic pole signal, forms an electrical signal feedback, and then controls the telescoping of the stepper motor 1, thereby controlling the angle required for the vehicle headlight illumination.
