[0001] This invention relates to the field of automotive lamp mounting bracket technology, specifically to an adjustable mounting bracket for automotive lamps and its operating method. Background Technology

[0002] Automotive headlights refer to various traffic lights installed on automobiles to ensure safe driving. When automotive lights are needed for illumination on the road at night, they focus light forward to achieve the effect of illumination. LED lighting technology initially appeared in automotive interior lighting and has gradually been applied to automotive exterior lighting such as headlights, turn signals, and taillights. Currently, most automotive lights are fixed in place using mounting brackets.

[0003] As shown in announcement number CN217197929U, an existing automotive headlight mounting bracket is named an adjustable automotive headlight mounting bracket. It includes a bracket body located at the center of the headlight reflector. The bracket body is cylindrical and has an inwardly rolled edge at the opening of the bracket body. The inwardly rolled edge has at least two arc-shaped grooves. The middle part of the headlight body has an outwardly protruding ring for abutting against the inwardly rolled edge. The ring has a threaded hole. The ring is connected to the bracket body by a bolt adapted to the threaded hole passing through the arc-shaped groove. A barbed spring is fixedly provided on the side wall of the inwardly rolled edge. The surface of the headlight body has a connection structure adapted to the barb.

[0004] However, there are many types of automotive lamps, including those with high manufacturing costs such as LED and laser lamps. Existing automotive lamp brackets are fixed installation structures, which cause the lamps to be damaged first when the lamps are hit, resulting in high repair costs. Therefore, we provide an adjustable mounting bracket for automotive lamps and its operation method. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable mounting bracket for automotive lamps and its operating method, in order to solve the problem mentioned in the background art that existing automotive lamp brackets are fixed mounting structures, which cause the lamps to be damaged first when the lamps are hit, resulting in high maintenance costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable mounting bracket for automotive lamp bodies, comprising a lamp body bracket;

[0007] Also includes:

[0008] A hydraulic cylinder positioning plate is installed at the rear end of the lamp body bracket. A buffer section is provided at the front end of the lamp body bracket.

[0014] The vehicle control central processor sends a signal to the hydraulic system, which drives the hydraulic cylinder to move and extend the car headlight to the reflector to achieve the lighting function. When there is sufficient light and no lighting is needed or the vehicle is parked, the vehicle control central processor sends a signal to the hydraulic system to drive the hydraulic cylinder to retract, so that the car headlight is housed in the protective block of the headlight bracket for protection. If the headlight is involved in a collision under these conditions, damage to the headlight can be avoided as much as possible, reducing subsequent maintenance costs.

[0015] Preferably, the inner wall of the reflector is provided with a stepped inner liner, and the stepped inner liner is integrally formed with the reflector, and the inner wall of the stepped inner liner is provided with a reflective film.

[0016] Preferably, the outer wall of the buffer section is provided with connecting rods, and four connecting rods are provided. The reflector connecting section and the lamp body bracket are fixedly connected by the connecting rods. A rubber layer is provided between adjacent connecting rods. The buffer section is provided with shock-absorbing buffer columns on all four sides. Four shock-absorbing buffer columns are provided, and the two ends of the four shock-absorbing buffer columns are fixedly connected to the lamp body bracket and the support plate, respectively.

[0017] Preferably, the shock-absorbing buffer column includes an inner tube and an outer tube. The outer tube has a buffer groove inside. One end of the inner tube extends into the buffer groove and is equipped with a damping guide rod. A second shock-absorbing spring is provided outside the damping guide rod, and the two ends of the second shock-absorbing spring are fixedly connected to the inner wall of the inner tube and the inner wall of the buffer groove, respectively.

[0018] Preferably, the rear end face of the support plate is provided with triangular reinforcing plates on all four sides, and there are eight triangular reinforcing plates, all of which are welded to the inner wall of the lamp body bracket.

[0019] Preferably, the protective block has a storage groove inside, and the rear end of the storage groove extends to the inner wall of the lamp body bracket. A first shock-absorbing spring is installed inside the storage groove.

[0020] Preferably, a power connector is installed at the connection between the output end of the hydraulic cylinder and the automotive lamp body. The rear end of the automotive lamp body is threadedly connected to the power connector via a threaded head. One end of the threaded head is provided with a power connector plate. A power supply harness is installed at the rear end of the power connector, and the power supply harness passes through and extends to the rear end of the lamp body bracket.

[0021] Preferably, a sealing cover is installed on the outer wall of the lamp body bracket, and a handle is installed on the outer wall of the sealing cover. One side of the sealing cover is rotatably connected to the lamp body bracket via a hinge, and the other side of the sealing cover is magnetically attracted to the lamp body bracket via a magnetic block.

[0022] Preferably, the input end of the hydraulic cylinder is connected to the output end of the hydraulic system, the input end of the hydraulic system is electrically connected to the output end of the central processing unit, the input end of the central processing unit is electrically connected to the output end of the vehicle automatic collision avoidance system, the vehicle automatic collision avoidance system includes an information acquisition system and a data processing system, and the output end of the information acquisition system is electrically connected to the input end of the data processing system.

[0023] Preferably, an operating method for an adjustable mounting bracket for an automotive lamp body includes the following steps:

[0024] Step 1: First, install the car light body. During installation, drive the hydraulic cylinder to adjust the electrical connector on the output end of the hydraulic cylinder to the lower middle position inside the light body bracket. Then, apply force with the handle to separate the sealing cover from the magnetic block. Use the hinge to rotate and open the sealing cover to expose the inner cavity of the light body bracket. Place the car light body into the inner cavity and screw the electrical connector into the rear threaded end of the car light body. After completion, close the sealing cover to complete the installation of the car light body.

[0025] Step 2: When the vehicle needs lighting, the vehicle control central processor sends a signal to the hydraulic system, driving the hydraulic cylinder to extend the car headlight to the reflector, thus achieving the lighting function. The reflector liner is stepped. When it is necessary to adjust the illuminance and illumination range, the hydraulic cylinder can be further driven to fine-tune the length of the car headlight extending into the reflector. Based on the extension length of the car headlight and the reflective effect of the reflective film on the different stepped liner of the reflector, the illuminance and illumination range of the car headlight can be adjusted.

[0026] Step 3: When there is sufficient light and no lighting is needed or the vehicle is parked, the vehicle control central processing unit will send a signal to the hydraulic system to drive the hydraulic cylinder to retract, so that the car headlight body is housed in the protective block of the headlight bracket for protection. If the headlight position of the vehicle is involved in a collision under these conditions, damage to the headlight body can be avoided as much as possible, reducing subsequent repair costs.

[0027] Step Four: When the vehicle's headlights are on, the driver can selectively activate the linkage between the headlights and the vehicle's automatic collision avoidance system. This system comprises an information acquisition system and a data processing system. The information acquisition system uses components such as millimeter-wave radar, laser, sonar, infrared, and cameras to measure the vehicle's speed, the speed of the vehicle in front, and the distance between the two vehicles in real time. This information is then fed back to the data processing system. After processing the distance and instantaneous relative speed of the two vehicles, the system determines the safe distance between them. If the distance is less than the safe distance, the data processing system issues a command. Based on the collision time, it sends a signal to the vehicle's central processing unit (CPU) before the collision. The CPU then sends the signal to the hydraulic system, driving the hydraulic cylinders to retract the headlights at high speed. After the headlights are retracted, the impact force from the collision is directly absorbed by the shock-absorbing mechanism behind the reflector. This mechanism consists of four shock-absorbing pillars and a support plate, minimizing the impact force to reduce the impact of the accident and lower subsequent repair costs.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. This invention, by setting a hydraulic cylinder on a mounting bracket and fixing the car lamp body to the electrical connector at the output end of the hydraulic cylinder using a threaded mounting method, allows the vehicle control central processing unit to send a signal to the hydraulic system when the vehicle's operating environment requires lighting. This drives the hydraulic cylinder to extend the car lamp body to the reflector, achieving the lighting function. When there is sufficient light and no lighting is needed, or when the vehicle is parked, the vehicle control central processing unit sends a signal to the hydraulic system to retract the hydraulic cylinder, retracting the car lamp body into the protective block of the lamp body bracket for protection. If a collision occurs at the vehicle's lamp position under these conditions, damage to the car lamp body can be minimized, reducing subsequent repair costs. This invention solves the problem that existing car lamp body brackets are fixed installation structures, which cause the lamp body to be damaged first and have high repair costs when the lamp body is impacted.

[0030] 2. In this invention, the input end of the hydraulic cylinder is connected to the output end of the hydraulic system, the input end of the hydraulic system is electrically connected to the output end of the central processing unit, and the input end of the central processing unit is electrically connected to the output end of the vehicle automatic collision avoidance system. The vehicle automatic collision avoidance system comprises two parts: an information acquisition system and a data processing system. The information acquisition system consists of acquisition components such as millimeter-wave radar, laser, sonar, infrared, and cameras, capable of measuring the speed of the current vehicle, the speed of the vehicle in front, and the distance between the two vehicles in real time, and feeding this information back to the data processing system to analyze the distance between the two vehicles and their instantaneous movement. After processing the relative speed, the system determines the safe distance between the two vehicles. If the distance between the two vehicles is less than the safe distance, the data processing system will issue an instruction. Based on the collision time of the two vehicles, a signal is sent to the vehicle control central processor before the collision. The vehicle control central processor then sends the signal to the hydraulic system, which drives the hydraulic cylinder to retract and retract the car headlight body at high speed. After the car headlight body is retracted, the impact force of the collision at the headlight is directly absorbed by the shock absorption mechanism behind the reflector. The shock absorption mechanism consists of four shock-absorbing buffer columns and a support plate, which can reduce the impact force as much as possible, thereby reducing the impact of the accident and reducing subsequent maintenance costs.

[0031] 3. By designing the reflector liner with a stepped structure, when it is necessary to adjust the illuminance and illumination range of the car headlights, the hydraulic cylinder can be driven to operate and finely adjust the length of the car headlight extending into the reflector. Based on the extension length of the car headlight and the reflective effect of the reflective film on the different stepped liner of the reflector, the illuminance and illumination range of the car headlights can be adjusted to adapt to different driving environments.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Please see Figure 1-5 An embodiment of the present invention provides: an adjustable mounting bracket for automotive lamp bodies, comprising a lamp body bracket 1;

[0043] Also includes:

[0044] The hydraulic cylinder positioning plate 2 is installed at the rear end of the lamp body bracket 1. The front end of the lamp body bracket 1 is provided with a buffer section 6, the front end of the buffer section 6 is provided with a reflector connecting section 7, and the front end of the reflector connecting section 7 is provided with a reflector 8.

[0045] The automotive lamp body 12 is located inside the reflector 8;

[0046] Hydraulic cylinder 3 is installed at the rear end of hydraulic cylinder positioning plate 2. The output end of hydraulic cylinder 3 passes through hydraulic cylinder positioning plate 2 and extends into the interior of lamp body bracket 1, and is connected to the rear end of automotive lamp body 12.

[0047] Support plate 15, which is installed at the upper end inside the lamp body bracket 1;

[0048] Protective block 19 is installed at the lower end inside the lamp body bracket 1;

[0049] The lamp body through hole 17 is provided at one end of the lamp body bracket 1 and inside the support plate 15. The inner wall of the lamp body through hole 17 at one end of the lamp body bracket 1 is provided with an anti-wear positioning ring 11.

[0050] In use, the vehicle control central processor sends a signal to the hydraulic system, driving the hydraulic cylinder 3 to move and extend the car lamp body 12 to the reflector 8 to achieve the lighting function. When there is sufficient light and no lighting is needed or the vehicle is parked, the vehicle control central processor sends a signal to the hydraulic system to drive the hydraulic cylinder 3 to retract, so that the car lamp body 12 is housed in the protective block 19 of the lamp body bracket 1 for protection. If the vehicle's headlight position is involved in a collision under these conditions, damage to the car lamp body 12 can be avoided as much as possible, reducing subsequent maintenance costs. This avoids the situation where the existing car lamp body bracket is a fixed installation structure, and the headlight will be damaged first when it is hit by a collision, resulting in high maintenance costs.

[0051] Please see Figure 1 The reflector 8 has a stepped inner liner 9 on its inner wall, and the stepped inner liner 9 is integrally formed with the reflector 8. A reflective film 10 is provided on the inner wall of the stepped inner liner 9. When it is necessary to adjust the illuminance and illumination range, the hydraulic cylinder 3 can be driven to fine-tune the length of the car lamp body 12 extending into the reflector 8. Based on the extension length of the car lamp body 12 and the reflective effect of the reflective film 10 on the different stepped inner liners of the reflector 8, the illuminance and illumination range of the car lamp can be adjusted to adapt to different driving environments.

[0052] Please see Figure 2 The outer wall of the buffer section 6 is provided with connecting rods 14, and there are four connecting rods 14. The reflector connecting section 7 and the lamp body bracket 1 are fixedly connected by the connecting rods 14. A rubber layer 13 is provided between adjacent connecting rods 14. The buffer section 6 is provided with shock-absorbing buffer columns 16 on all four sides. There are four shock-absorbing buffer columns 16, and the two ends of the four shock-absorbing buffer columns 16 are fixedly connected to the lamp body bracket 1 and the support plate 15 respectively. When the vehicle headlight collides, the impact force can be directly absorbed by the shock-absorbing buffer columns 16 behind the reflector 8. There are four shock-absorbing buffer columns 16, which can reduce the impact force as much as possible to reduce the impact of the accident.

[0053] Please see Figure 5 The shock-absorbing buffer column 16 includes an inner tube 161 and an outer tube 162. The outer tube 162 has a buffer groove 163 inside. One end of the inner tube 161 extends into the buffer groove 163 and is equipped with a damping guide rod 165. A second damping spring 164 is provided outside the damping guide rod 165, and the two ends of the second damping spring 164 are fixedly connected to the inner wall of the inner tube 161 and the inner wall of the buffer groove 163, respectively. When the shock-absorbing buffer column 16 is impacted, the inner tube 161 can contract along the buffer groove 163 inside the outer tube 162 and be buffered by the action of the second damping spring 164. Together with the damping guide rod 165, it achieves the effect of shock absorption and significantly reduces the impact force at that point.

[0054] Please see Figure 2 and Figure 6The support plate 15 has eight triangular reinforcing plates 18 on all four sides of its rear end face. All eight triangular reinforcing plates 18 are welded to the inner wall of the lamp body bracket 1. The triangular reinforcing plates 18 improve the structural strength of the support plate 15, enabling it to better support the shock-absorbing buffer column 16.

[0055] Please see Figure 3 The protective block 19 has a storage groove 21 inside, and the rear end of the storage groove 21 extends to the inner wall of the lamp body bracket 1. A first shock-absorbing spring 22 is installed inside the storage groove 21. When the car lamp body 12 retracts into the storage groove 21 of the protective block 19 at high speed under the action of the hydraulic cylinder 3, the first shock-absorbing spring 22 can dampen and buffer the car lamp body 12 entering the storage groove 21 to prevent damage to the car lamp body 12.

[0056] Please see Figure 2 and Figure 7 A power connector 24 is installed at the connection between the output end of the hydraulic cylinder 3 and the automotive lamp body 12. The rear end of the automotive lamp body 12 is threadedly connected to the power connector 24 via a threaded head 25. One end of the threaded head 25 is provided with a power connector 26. A power supply harness is installed at the rear end of the power connector 24, and the power supply harness passes through and extends to the rear end of the lamp body bracket 1. The automotive lamp body 12 is screwed into the power connector 24 using the threaded head 25, which makes disassembly and assembly convenient and efficient.

[0057] Please see Figure 1 and Figure 4 A sealing cover 4 is installed on the outer wall of the lamp body bracket 1. A handle 5 is installed on the outer wall of the sealing cover 4. One side of the sealing cover 4 is rotatably connected to the lamp body bracket 1 through a hinge 23, and the other side of the sealing cover 4 is magnetically attracted to the lamp body bracket 1 through a magnetic block 20. The sealing cover 4 is fixed to the lamp body bracket 1 by magnetic attraction, which makes it easy to open and close and convenient for inspection and maintenance.

[0058] Please see Figure 8The input end of hydraulic cylinder 3 is connected to the output end of the hydraulic system, which is electrically connected to the output end of the central processing unit. The input end of the central processing unit is electrically connected to the output end of the automatic collision avoidance system. The automatic collision avoidance system includes an information acquisition system and a data processing system. The output end of the information acquisition system is electrically connected to the input end of the data processing system. The information acquisition system consists of acquisition components such as millimeter-wave radar, laser, sonar, infrared, and camera. It can measure the speed of the vehicle itself, the speed of the vehicle in front, and the distance between the two vehicles in real time, and feed this information back to the data processing system. After processing the distance between the two vehicles and the instantaneous relative speed of the two vehicles, the system determines the safe distance between the two vehicles. If the distance between the two vehicles is less than the safe distance, the data processing system will issue an instruction to send a signal to the vehicle control central processing unit before the collision, based on the collision time of the two vehicles. The vehicle control central processing unit will then send the signal to the hydraulic system, driving hydraulic cylinder 3 to retract and store the car lamp body 12 at high speed to protect it.

[0059] Please see Figure 1-8 An operating method for an adjustable mounting bracket for an automotive lamp body includes the following steps:

[0060] Step 1: First, install the car lamp body 12. During installation, drive the hydraulic cylinder 3 to adjust the electrical connector 24 on the output end of the hydraulic cylinder 3 to the lower middle position inside the lamp body bracket 1. Then, apply force through the handle 5 to separate the sealing cover 4 from the magnetic block 20. Use the hinge 23 to rotate and open the sealing cover 4 to expose the inner cavity of the lamp body bracket 1. Place the car lamp body 12 into the inner cavity and screw the threaded head 25 at the rear end of the car lamp body 12 into the electrical connector 24. After completion, close the sealing cover 4 to complete the installation of the car lamp body 12.

[0061] Step 2: When the vehicle needs lighting, the vehicle control central processor sends a signal to the hydraulic system, driving the hydraulic cylinder 3 to move and extend the car lamp body 12 to the reflector 8 to achieve the lighting function. The reflector 8 has a stepped inner lining. When it is necessary to adjust the illuminance and illumination range, the hydraulic cylinder 3 can be further driven to fine-tune the length of the car lamp body 12 extending into the reflector 8. Based on the extension length of the car lamp body 12 and the reflective effect of the reflective film 10 on the different stepped inner linings of the reflector 8, the illuminance and illumination range of the car lamp can be adjusted.

[0062] Step 3: When there is sufficient light and no lighting is needed or the vehicle is parked, the vehicle control central processor will send a signal to the hydraulic system to drive the hydraulic cylinder 3 to retract, so that the car lamp body 12 is housed in the protective block 19 of the lamp body bracket 1 for protection. If the vehicle's headlight position is involved in a collision under these conditions, damage to the car lamp body 12 can be avoided as much as possible, reducing subsequent maintenance costs.

[0063] Step Four: When the vehicle lights are on, the driver can selectively activate the linkage between the lights and the vehicle's automatic collision avoidance system. The automatic collision avoidance system consists of two parts: an information acquisition system and a data processing system. The information acquisition system is composed of collection components such as millimeter-wave radar, laser, sonar, infrared, and cameras. It can measure the speed of the vehicle in real time, the speed of the vehicle in front, and the distance between the two vehicles, and feed this information back to the data processing system. After processing the distance between the two vehicles and their instantaneous relative speed, the system determines the safe distance between the two vehicles. If the distance between the two vehicles is less than the safe distance, the data processing system will issue an instruction. Based on the collision time of the two vehicles, a signal is sent to the vehicle control central processor before the collision. The vehicle control central processor sends the signal to the hydraulic system, which drives the hydraulic cylinder 3 to retract and retract the car light body 12 at high speed. After the car light body 12 is retracted, the impact force of the collision at the headlight is directly absorbed by the shock absorption mechanism behind the reflector 8. The shock absorption mechanism consists of four shock-absorbing buffer columns 16 and a support plate 15, which can reduce the impact force as much as possible, thereby reducing the impact of the accident and reducing subsequent maintenance costs.

[0064] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

During installation, drive the hydraulic cylinder (3) to run, so that the electrical connector (24) on the output end of the hydraulic cylinder (3) is adjusted to the lower middle position inside the lamp body bracket (1). Then, apply force through the handle (5) to separate the sealing cover (4) from the magnetic block (20). Use the hinge (23) to rotate and open the sealing cover (4) to expose the inner cavity of the lamp body bracket (1). Place the car lamp body (12) into the inner cavity and use the threaded head (25) at the rear end of the car lamp body (12) to screw it into the electrical connector (24). After completion, close the sealing cover (4) to complete the installation of the car lamp body (12). Step 2: When the vehicle needs lighting, the vehicle control central processor sends a signal to the hydraulic system to drive the hydraulic cylinder (3) to move and drive the car lamp body (12) to extend to the reflector (8) to realize the lighting function. The inner lining of the reflector (8) is stepped. When it is necessary to adjust the illuminance and illumination range, the hydraulic cylinder (3) can be driven to move and finely adjust the length of the car lamp body (12) extending into the reflector (8). According to the extension length of the car lamp body (12) and the reflective effect of the reflective film (10) on the different stepped inner lining of the reflector (8), the illuminance and illumination range of the car lamp can be adjusted. Step 3: When there is sufficient light and no lighting is needed or the vehicle is parked, the vehicle control central processor will send a signal to the hydraulic system to drive the hydraulic cylinder (3) to retract, so that the car lamp body (12) is stored in the protective block (19) of the lamp body bracket (1) for protection. Step Four: When the vehicle's headlights are on, the driver can selectively activate the linkage between the headlights and the vehicle's automatic collision avoidance system. This system comprises two parts: an information acquisition system and a data processing system. The information acquisition system, consisting of millimeter-wave radar, laser, sonar, infrared, and cameras, can measure the vehicle's speed, the speed of the vehicle in front, and the distance between the two vehicles in real time, feeding this data back to the data processing system. After processing the distance and instantaneous relative speed of the two vehicles, the system determines the safe distance between them. If the distance between the two vehicles is less than the safe distance... Upon collision, the data processing system will issue an instruction to send a signal to the vehicle control central processor before the collision, based on the collision time of the two vehicles. The vehicle control central processor will then send the signal to the hydraulic system, driving the hydraulic cylinder (3) to retract and store the car lamp body (12) at high speed. After the car lamp body (12) is stored, the impact force after the collision at the headlight is directly absorbed by the shock absorption mechanism behind the reflector (8). The shock absorption mechanism consists of four shock absorption buffer columns (16) and a support plate (15), which can reduce the impact force as much as possible, thereby reducing the impact of the accident and lowering subsequent maintenance costs.
