Description
Technical Field
[0001] The utility model relates to the technical field of automobile lamps, in particular to a non-destructive installation intelligent follow-up steering bi-xenon lens lamp. Background Art
[0002] Some high-end cars on the market have the function of steering follow-up for their lamps, but some low-equipped cars do not have this function. When upgrading halogen bulbs to LED lamps, if you want to upgrade the steering follow-up function, unless the original car has the function of steering follow-up, otherwise it is impossible to upgrade the LED lamp and the steering follow-up function at the same time. Later, some steering follow-up lens lamps appeared on the market. When installing the steering follow-up lens lamp, it is necessary to punch holes in the original lamp cup and fix the steering follow-up lens lamp on the original lamp cup with screws. Since the punching position is often inaccurate and the punching position is prone to deviation during manual punching of the original lamp cup, the installation screw holes of the steering follow-up lens lamp do not correspond to the holes on the original lamp cup, resulting in installation failure. Or although some lamps are installed successfully, their light irradiation will deviate due to the improper installation of the steering follow-up lens lamp, ultimately affecting the driving lighting effect. Summary of the Invention
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a non-destructive installation intelligent follow-up steering bi-xenon lens lamp.
[0004] To solve the above technical problems, the utility model adopts the following technical solutions: The non-destructive installation intelligent follow-up steering bi-xenon lens lamp includes a quick-installation bracket. A fixed frame is fixedly installed at the front end of the quick-installation bracket. An installation screw is provided at the rear end of the quick-installation bracket. The installation screw is integrally formed with the quick-installation bracket. A fixing nut is screwed on the installation screw. The lens lamp is installed in the original lamp cup through the fixing nut and the installation screw. A follow-up heat dissipation frame is installed in the fixed frame. The upper and lower ends of the follow-up heat dissipation frame are respectively installed in the fixed frame through hinge pins. The follow-up heat dissipation frame rotates left and right in the fixed frame through the hinge pins. A radiator, an LED light source, an installation bracket and a PCB board are respectively arranged in the follow-up heat dissipation frame from top to bottom. A stepping motor is fixedly installed on the installation bracket. A fork is provided at the output end of the stepping motor. The lower end of the fork is recessed inward to form a fork groove. A transmission plate extends laterally at the lower end of the fixed frame. A gyroscope for sensing the steering of the vehicle is provided on the transmission plate. A driving slot hole is provided through the center of the transmission plate. A pin rod is movably installed in the driving slot hole. A steel ball is provided on the pin rod. The pin rod penetrates through the fork groove of the fork, and the steel ball is accommodated in the fork groove.
[0005] By adopting the above technical solutions, a follow-up heat dissipation frame is installed inside a fixed frame, and the follow-up heat dissipation frame is installed inside the fixed frame by using pivot pins at the upper and lower ends of a fixed bracket. The pivot pins function as rotating shafts. It also fixes the fixed frame to the front end of a quick-install bracket and provides an installation screw at the rear end of the quick-install bracket. The installation screw is integrally formed with the quick-install bracket, enabling the lens headlight to be quickly installed in the lamp cup hole of the original headlight through a fixing nut and the installation screw, thus completing the modification of the headlight. It not only has the advantages of simple and convenient installation of the lens headlight, high installation efficiency of the lens headlight, high installation positioning accuracy of the lens headlight, and lighting effect of the lens headlight comparable to that of the original vehicle lens headlight, but also effectively replaces the method of manually drilling holes in the original headlight cup during traditional headlight modification, which may cause the installation screw holes of the steering follow-up lens headlight not to correspond to the hole positions on the lamp cup of the original headlight, resulting in installation failure or deviation of the lighting due to incorrect installation position of the steering follow-up lens headlight. When the stepper motor drives the fork to swing left and right, since the fixed frame is fixed inside the original headlight cup through the quick-install bracket, the pin rod is installed on the transmission plate of the fixed frame, and the steel ball is fixedly installed on the pin rod. When the fork swings, it is driven by the reaction force of the steel ball to drive the follow-up heat dissipation frame to rotate in the direction opposite to the swing of the fork, enabling the follow-up heat dissipation frame to rotate left and right inside the fixed frame, so as to realize the relative rotation of the follow-up heat dissipation frame with respect to the fixed frame, and finally achieve the follow-up steering of the headlight.
[0006] Further, a power supply interface, an LED driver, an MCU (microcontroller), and a motor driver are provided on the PCB board. The power supply interface is electrically connected to the LED driver and the motor driver respectively. The LED driver, the motor driver, and the gyroscope are respectively signal-connected to the MCU. The power supply interface is externally connected to the vehicle lighting power supply system.
[0007] By adopting the above technical solutions, it is electrically connected to the vehicle lighting power supply system through the power supply interface, enabling the power supply interface to supply power to the operation of components such as the motor driver, the stepper motor, the LED driver, and the LED light source.
[0008] Further, the motor driver is drivingly connected to the stepper motor, and the LED driver is drivingly connected to the LED light source.
[0009] By adopting the above technical solution, when the gyroscope senses that the vehicle is turning, it will send the sensed steering signal to the MCU. After receiving the vehicle steering signal fed back by the gyroscope, the MCU will send a control signal to the motor driver. After receiving the signal sent by the MCU, the motor driver will send a steering instruction (or start working instruction) to the stepping motor. The stepping motor rotates forward and backward to drive the fork to swing left and right. The swinging fork is subjected to the reaction force of the steel ball and can drive the follower heat sink to rotate in the direction opposite to the swing of the fork to realize the follow-up steering of the vehicle lamp, so that it can be realized that according to the direction of vehicle turning, the stepping motor is commanded to drive the follower heat sink to make corresponding direction and angle steering. Similarly, when the MCU sends a control instruction to the LED driver, the LED driver can control the LED light source to start working or stop working after receiving the control instruction.
[0010] Further, a reflector cup is provided on one side of the radiator, and a cooling fan is provided on the other side of the radiator. The cooling fan is installed at the rear end of the follower heat sink.
[0011] By adopting the above technical solution, when the heat generated by the long-term operation of the LED light source is transferred to the radiator, the cooling fan can blow air to cool the radiator, so as to extend the service life of the LED light source.
[0012] Further, a lens bracket is installed on the front side of the follower heat sink, and a convex lens is installed inside the lens bracket.
[0013] Further, an upper cover is installed on the follower heat sink, and a lower cover is installed under the follower heat sink.

[0016] 1. It is provided with an installation screw at the rear end of the quick - installation bracket. The installation screw is integrally formed with the quick - installation bracket. A fixing nut is provided on the installation screw. The lens headlight is inserted into the bulb installation hole of the original headlight cup through the installation screw of the quick - installation bracket, and then locked with the installation screw through the fixing nut to fix the lens headlight in the original headlight cup, thus completing the modification of the headlight. It can achieve the upgrade of the headlight with follow - up steering function even when the original vehicle does not have a follow - up steering structure. It does not need to drill holes in the original headlight cup, and has the advantages of simple installation, convenient installation, accurate installation positioning, high installation efficiency, low installation cost and strong product versatility. The lighting effect after installing the structure of the present utility model with the original headlight cup is comparable to that of the original vehicle's lens headlight. It not only effectively solves the problem that when upgrading the steering follow - up function of traditional headlights, manual drilling of the original headlight cup is prone to inaccurate drilling positioning and deviation of the drilling position, resulting in non - correspondence between the installation screw holes of the steering follow - up lens headlight and the hole positions on the lamp cup, but also solves the problem that even if the traditional headlight is successfully installed with the steering follow - up lens headlight, the light irradiation often deviates due to the incorrect installation position of the steering follow - up lens headlight, affecting the driving lighting effect.
[0017] 2. It is fixedly installed with a stepper motor on the installation bracket. A fork is provided at the output end of the stepper motor, and a transmission plate is laterally extended at the lower end of the fixed frame. A gyroscope for sensing vehicle steering is provided on the transmission plate. Inside the follow - up heat dissipation frame, there are a radiator, an LED light source, an installation bracket and a PCB board from top to bottom respectively; when the gyroscope senses that the vehicle is turning, the MCU receives the vehicle steering signal fed back from the gyroscope and controls the stepper motor to rotate through the motor driver to drive the fork to swing. When the fork swings, it will be affected by the reaction force of the steel ball installed on the pin rod and drive the follow - up heat dissipation frame installed in the fixed frame to rotate in the direction opposite to the swing direction of the fork, so as to realize the rotation of the follow - up heat dissipation frame relative to the fixed frame. It can achieve corresponding rotation and angular steering of the follow - up heat dissipation frame according to the vehicle's steering command or by controlling the stepper motor, so that the steering angle of the follow - up heat dissipation frame can be consistent with the vehicle's steering angle, and finally realizes the follow - up steering of the headlight.

[0035] In one of the embodiments, the structural design principle of the lossless installation intelligent follow-up steering dual-light lens car light is as follows: a follow-up heat dissipation frame 5 is installed in the fixed frame 2, and the upper and lower ends of the follow-up heat dissipation frame 5 are installed in the fixed frame 2 through axle pins 6. The axle pin 6 acts as a rotating shaft, so that the follow-up heat dissipation frame 5 can rotate left and right in the fixed frame 2 through the axle pin 6. The modification of the headlight is completed by fixing the fixing frame 2 on the front end of the quick-release bracket 1 and providing a mounting screw 3 on the rear end of the quick-release bracket 1. The quick-release bracket 1 installs the lens headlight in the original headlight cup through the fixing nut 4 and the mounting screw 3. There is no need to manually punch holes in the original headlight cup. The lens headlight has the advantages of accurate installation positioning, simple installation, convenient installation, high installation efficiency, good installation effect and ensuring that the lighting effect is comparable to the original vehicle lens headlight. It not only effectively solves the problem that manual drilling of headlights is prone to inaccurate positioning and deviation in the drilling position, resulting in the mismatch between the mounting screw hole of the steering follow-up lens headlight and the hole position on the original headlight cup, causing the installation of the follow-up lens headlight and the original headlight cup to fail, but also solves the problem that even if the steering follow-up lens headlight and the original headlight cup are barely installed successfully, the incorrect installation position will lead to deviation in the light illumination of the headlight and poor driving lighting effect.
[0036] The stepper motor 11 is fixedly mounted on the mounting bracket 9, a shift fork 12 is provided at the output end of the stepper motor 11, a fork groove 13 is provided at the lower end of the shift fork 12, a transmission plate 14 is provided at the lower end of the fixed frame 2, a driving slot 16 is provided through the center of the transmission plate 14, a pin 17 is movably installed in the driving slot 16, a steel ball 18 is provided on the pin 17, the pin 17 passes through the fork groove 13 of the shift fork 12, and the steel ball 18 is accommodated in the fork groove 13; when the stepper motor 11 is in the When rotating in the opposite direction, the shift fork 12 can be driven to swing left and right. Since the fixed frame 2 is fixed in the original lamp cup by the quick-release bracket 1, when the shift fork 12 swings, it will be subjected to the reaction force of the steel ball 18 and push the follow-up heat sink 5 installed in the fixed frame 2 through the transmission plate 14 to rotate in the opposite direction of the swing of the shift fork 12, so as to realize the rotation of the follow-up heat sink 5 relative to the fixed frame 2, and the LED light source 8 arranged in the follow-up heat sink 5 can rotate with the rotation of the follow-up heat sink 5, finally realizing the follow-up steering of the lamp.
[0037] It also has a gyroscope 15 for sensing the vehicle's steering on the drive plate 14, and a power supply interface 19, an LED driver 20, an MCU 21, and a motor driver 22 on the PCB board 10 in the follower heat dissipation frame 5. The power supply interface 19 is externally connected to the vehicle lighting power supply system to supply power to the operation or work of components such as the motor driver 22, the stepping motor 11, the LED driver 20, and the LED light source 8. When the gyroscope 15 senses that the vehicle is turning, it sends a sensing signal to the MCU 21. After receiving the vehicle turning signal fed back from the gyroscope 15, the MCU 21 sends a signal to the motor driver 22. After receiving the signal from the MCU 21, the motor driver 22 sends a start working instruction and a steering instruction to the stepping motor 11, enabling it to command the stepping motor 11 to drive the follower heat dissipation frame 5 to rotate in the corresponding direction and turn at an angle according to the vehicle's turn. That is, it can automatically control the turning angle and direction of the follower heat dissipation frame 5 by the stepping motor 11 to be consistent with the turning angle and direction of the vehicle, so as to avoid deviation of the headlight illumination and affect the driving lighting effect.
[0038] It also has a cooling fan 23 on one side of the radiator 7. When the heat generated by the operation of the LED light source 8 is transferred to the radiator 7, the radiator 7 dissipates heat from the LED light source 8, and the cooling fan 23 blows air on the radiator 7 for active heat dissipation, enabling it to reduce the working temperature of the LED light source 8 and thus extend the service life of the LED light source 8.
[0039] The overall structural design can simply and quickly install the lens headlight in the original headlight cup through the fixing nut 4 and the mounting screw 3 to complete the modification of the headlight. It enables the original headlight of the vehicle to upgrade to have the function of follow - up steering without a follow - up steering structure. Moreover, the dual - light lens headlight of this product is small in size, facilitating installation with original headlight cups of different specifications. During installation, there is no need to drill additional installation holes, achieving a damage - free installation. It has the advantages of simple and convenient installation, low installation cost, high installation efficiency, and strong versatility, effectively solving the trouble of drilling screw holes in the original headlight cup for installing a follow - up steering lens headlight for traditional headlights.
