Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting system testing technology, and in particular to an auxiliary device for testing the performance of adaptive headlights. Background Technology

[0002] Adaptive high beam technology is an advanced headlight system that intelligently adjusts the illumination distance to adapt to constantly changing driving conditions, significantly improving nighttime driving safety. This headlight system uses a high-sensitivity camera installed in the rearview mirror area to accurately identify the taillights of vehicles ahead and the headlights of oncoming vehicles. Once an oncoming vehicle is detected, the system automatically switches from high beam to low beam mode to avoid dazzling other drivers; when the path is clear and there are no vehicles, it seamlessly switches back to high beam to ensure optimal visibility. No manual intervention from the driver is required throughout the process, greatly reducing driving burden and ensuring the safety of both parties on the road.

[0003] During the development and testing phase of this headlight system, functional testing and calibration must be conducted not only in public road environments but also at professional test tracks to ensure safe and reliable performance. However, traditional methods rely on using real vehicles as targets to simulate different driving scenarios. This not only requires the cooperation of the target vehicles but is also limited by nighttime testing time and personnel arrangements, making headlight performance testing difficult to implement and posing certain safety risks during the testing process.

[0007] The vehicle light mounting components are two sets located at the front and rear ends of the vehicle frame. Each set of vehicle light mounting components includes a mounting bracket and an adjustment component that is slidably mounted on the mounting bracket along the chassis height direction. The adjustment component located at the front end of the vehicle frame is equipped with a headlight module, and the adjustment component located at the rear end of the vehicle frame is equipped with a taillight module. The headlight module and the taillight module are two units arranged at intervals along the chassis width direction, and the positions of each headlight module and each taillight module are adjustable along the chassis width direction.

[0008] Furthermore, the mounting bracket includes a connecting base connected to the vehicle frame and a support rod connected to the connecting base, the support rod extending along the height direction of the chassis; the adjustment component is slidably disposed on the support rod.

[0009] Furthermore, the support rod is detachably connected to the connecting base.

[0010] Furthermore, the support rod is detachably connected to the connecting base by two spaced-apart connecting pins. The two connecting pins are spaced apart along the length of the support rod, and after one of the connecting pins is removed, the support rod can rotate around the other connecting pin to a storage position on the frame.

[0011] Furthermore, the connecting base is provided with fasteners for fixing the support rod to the support rod.

[0012] Furthermore, the adjustment assembly includes a first rod slidably disposed on the mounting bracket, and two second rods slidably disposed at both ends of the first rod; the first rod extends along the width direction of the chassis; the headlight module is respectively disposed on the two second rods located at the front end of the frame, and the taillight module is respectively disposed on the two second rods located at the rear end of the frame.

[0013] Furthermore, a first locking member is provided between the first rod and the mounting bracket, the first locking member being used to lock the first rod onto the mounting bracket; a second locking member is provided between each second rod and the first rod, the second locking member being used to lock the corresponding second rod onto the first rod.

[0014] Furthermore, the mounting bracket includes a connecting base connected to the vehicle frame and a first bracket connected to the connecting base; the first bracket is provided with a first linear drive device that drives the adjustment component to move along the chassis height direction, and a guide structure for guiding the movement of the adjustment component is provided between the first bracket and the adjustment component.

[0015] Furthermore, the adjustment assembly includes a mounting plate slidably disposed on the first bracket, a first slide rod and a second slide rod disposed on the mounting plate along the width direction of the chassis, and a second driving device that drives the first slide rod and the second slide rod to move synchronously in opposite directions; the two headlight modules are respectively disposed on the first slide rod and the second slide rod; or the two taillight modules are respectively disposed on the first slide rod and the second slide rod.

[0016] Furthermore, the length of the contoured vehicle chassis is between 1000mm and 1200mm; the width of the contoured vehicle chassis is between 800mm and 1000mm; and the height of the contoured vehicle chassis is between 350mm and 400mm.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The adaptive headlight performance testing auxiliary device of this utility model, by setting a remotely movable contour vehicle chassis and a headlight mounting component, allows the headlight and taillight modules to be adjusted in the width and height directions relative to the contour vehicle chassis. This enables better simulation of the headlight and taillight positions on a target vehicle, and can also match the headlight and taillight positions of different vehicle models, such as large and small vehicles. Therefore, when testing the adaptive headlight performance of a test vehicle, there is no need to rely on an external target vehicle. This not only reduces manpower and vehicle operating costs, but also improves testing efficiency, economy, and safety, and has excellent practical effects.

[0019] Furthermore, the mounting bracket includes a connecting base and a support rod, facilitating both the connection between the mounting bracket and the vehicle frame and the sliding arrangement of adjustable components. Its simple structure makes it easy to design and implement. The support rod is detachably connected to the connecting base, allowing for easy storage of the auxiliary device when not in use, and also saving space in the height direction of the contoured chassis. The support rod is detachably connected to the base via two spaced-apart connecting pins. This simple structure improves the convenience of installation and disassembly. After one connecting pin is removed, the support rod can rotate around the other connecting pin by a certain angle, that is, from a vertical to a horizontal position, which facilitates storage of the support rod on the vehicle frame.

[0020] Secondly, the fasteners installed on the connecting base ensure the reliability of the connection between the support rod and the connecting base, and help the support rod to be held in the correct position, thus improving the performance. The adjustment component includes a first rod slidably mounted on the mounting bracket, and two second rods slidably mounted on the first rod, with the first rod extending along the width of the chassis. Thus, by sliding the two second rods along the first rod, the headlight module and taillight module can be adjusted in position along the width of the chassis. Its structure is simple, low-cost, and easy to manufacture.

[0021] Furthermore, the first locking element ensures that the first rod is securely locked to the mounting bracket, guaranteeing that it remains on the bracket after movement. Similarly, the second locking element ensures that the corresponding second rod is securely locked to the first rod, guaranteeing that it remains on the first rod after movement. The mounting bracket includes a connecting base and a first support, with a first linear drive device mounted on the first support. This automates the movement of the adjustment components along the chassis height direction, thus automating the movement of the headlight and taillight modules relative to the mounting bracket in the chassis height direction. The guide structure further enhances the accuracy of the adjustment components' movement direction.

[0022] In addition, the adjustment assembly includes a mounting plate slidably mounted on the first bracket, a first slide rod and a second slide rod, and a second linear drive device. This allows the first and second slide rods to move synchronously in opposite directions via the second linear drive device, thereby automating the movement of the first and second slide rods along the width of the chassis, and consequently automating the movement of the headlight and taillight modules along the width of the chassis. Combined with the first linear drive device, this automates the adjustment of the headlight and taillight module positions, facilitating rapid adjustment of their positions. The limitations on the length, width, and height dimensions of the contour vehicle chassis allow for miniaturization, making it easy to store in the trunk of the vehicle under test and carry it with the vehicle, thus improving ease of use.

For example, the interior and exterior of the vehicle are defined based on its outline, with the side closer to the center of the vehicle being "inner" and the opposite side being "outer."

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] This embodiment relates to an auxiliary device for adaptive headlight performance testing, which helps to reduce manpower input and vehicle operating costs, and improve testing efficiency and safety.

[0037] In terms of overall structure, see Figure 1As shown, the adaptive headlight performance testing auxiliary device (hereinafter referred to as the auxiliary device) of this embodiment includes a remotely movable contour vehicle chassis 1 and a headlight mounting assembly mounted on the frame of the contour vehicle chassis 1.

[0038] The vehicle lighting mounting components consist of two sets located at the front and rear ends of the vehicle frame. Each set of vehicle lighting mounting components includes a mounting bracket and an adjustment component that slides along the height of the chassis on the mounting bracket. The adjustment component located at the front end of the vehicle frame is equipped with a headlight module 200, and the adjustment component located at the rear end of the vehicle frame is equipped with a taillight module 300. The headlight module 200 and the taillight module 300 are two units spaced apart along the width of the chassis, and the positions of each headlight module 200 and each taillight module 300 are adjustable along the width of the chassis.

[0039] In the above structure, by setting a remotely controllable movable contour vehicle chassis 1 and a set of vehicle light mounting components, the headlight module 200 and taillight module 300 are adjustable in the width and height directions relative to the contour vehicle chassis 1. This allows for better simulation of the headlight and taillight positions on the target vehicle. It can also match the headlight and taillight positions of different vehicle models, such as large vehicles and small vehicles. Therefore, when performing performance tests on the adaptive headlights of the test vehicle, it is not necessary to rely on an external target vehicle, which helps to reduce manpower input and vehicle operating costs, and improves testing efficiency and economy.

[0040] Meanwhile, by using the remotely controlled mobile contour vehicle chassis 1, test personnel can operate the contour vehicle chassis 1 from a safe distance, which can effectively avoid the safety hazards that may be caused by direct human interaction and help eliminate the accidental risks caused by improper cooperation of test personnel, thereby helping to ensure the safety and reliability of the test process.

[0041] It should be noted that the remotely controlled mobile contoured chassis of this embodiment has four wheels 100, and the contoured chassis is equipped with, for example, a battery system, a steering system, a braking system, a drive system, and a remote control device. The battery system provides power to the motor in the drive system. The steering system drives the wheels 100 to steer, the braking system brakes the wheels 100, and the drive system drives the vehicle to rotate. The remote control device includes, for example, a remote controller and a remote receiver mounted on the chassis. This remote control device is used to remotely control the movement of the contoured chassis and to remotely control the individual activation and deactivation of the headlight module 200 and / or taillight module 300, thus simulating the actual movement and lighting conditions of the target vehicle according to actual needs. The aforementioned battery system, steering system, braking system, drive system, and remote control device can all be implemented using existing mature technologies.

[0042] Additionally, it should be noted that the auxiliary device in this embodiment is used to assist in the performance testing of the adaptive headlights of the test vehicle. The headlight module 200 and taillight module 300, which are mounted on the contoured vehicle chassis 1, can specifically adopt the same headlights and taillights as the external target vehicle. For example, the headlights can be halogen, xenon, or LED lights, and the taillights generally include brake lights, reversing lights, turn signals, and fog lights, thus effectively simulating the lighting effect on the external target vehicle.

[0043] Furthermore, in this embodiment, the installation positions of the headlight module 200 and the taillight module 300 are adjustable, which can match the installation position of the external target vehicle, better simulate the position of the headlights and taillights on the target vehicle, and also match the headlights and taillights of different models such as large vehicles and small vehicles, which helps to improve the versatility of the auxiliary device.

[0044] Based on the above overview, in detail, the contoured vehicle chassis 1 has headlight mounting components at both the front and rear ends of the frame. Each headlight mounting component includes a mounting bracket and an adjustment component. The adjustment component is slidably mounted on the mounting bracket along the chassis height direction. The adjustment component at the front of the frame has headlight modules 200, which are arranged in pairs at intervals along the chassis width direction. The adjustment component at the rear of the frame has taillight modules 300, which are also arranged in pairs at intervals along the chassis width direction. The positions of each headlight module 200 and each taillight module 300 are adjustable along the chassis width direction.

[0045] As a preferred embodiment, in this embodiment, see... Figures 1 to 4 As shown, the mounting bracket includes a connecting base 2 connected to the vehicle frame and a support rod 3 connected to the connecting base 2, with the support rod 3 extending along the height direction of the chassis. The adjustment component is slidably mounted on the support rod 3. Here, the mounting bracket includes the connecting base 2 and the support rod 3. On the one hand, the connecting base 2 facilitates the connection between the mounting bracket and the vehicle frame; on the other hand, it also facilitates the sliding arrangement of the adjustment component on the support rod 3. Furthermore, the structure is simple and easy to design and implement.

[0046] In practice, the connecting base 2 is fixed to the vehicle frame, for example, by welding or screwing. The support rod 3 can be fixed to the connecting base 2 or detachably connected to the support rod 3. As a preferred embodiment, in this example, the support rod 3 is detachably connected to the connecting base 2. This arrangement allows for easy storage of the auxiliary device when it is not in use by removing the support rod 3, and also saves space in the height direction of the contoured chassis 1.

[0047] Specifically, in combination Figures 2 to 4As shown, in this embodiment, the support rod 3 is detachably connected to the connecting base 2 via two spaced-apart connecting pins 21, wherein the connecting pins 21 are arranged at intervals along the length of the support rod 3. After one connecting pin 21 is removed, the support rod 3 can rotate around the other connecting pin 21 to a storage position on the frame. The installation of the two connecting pins 21 ensures the support rod 3 remains in a vertical position, and the removal of the two connecting pins 21 improves the ease of disassembly. Furthermore, after one connecting pin 21 is removed, the support rod 3 can rotate around the other connecting pin 21 by a certain angle, that is, the support rod 3 rotates from a vertical state to a horizontal state, which facilitates the storage of the support rod 3 on the frame.

[0048] To facilitate the installation and disassembly of the connecting pin 21, a pull ring 211 is provided at the end of the connecting pin 21 in this embodiment. By operating the pull ring 211, the connecting pin 21 can be installed on the connecting base 2 or disassembled from the connecting base 2. This improves the convenience of operation and makes the installation and disassembly of the connecting pin 21 easier and less strenuous.

[0049] Furthermore, as a further preferred embodiment, in this embodiment, a fastener 22 is also provided on the connecting base 2. The fastener 22 is used to fix the support rod 3 to the connecting base 2. At this time, by tightening the support rod 3 with the fastener 22, the support rod 3 can be better maintained in the working position. This ensures the reliability of the connection between the support rod 3 and the connecting base 2 and improves the performance. In specific implementation, the fastener 22 is preferably a tightening bolt screwed onto the connecting base 2.

[0050] The adjustment component in this embodiment, as a preferred implementation, is described below. Figure 2 and Figure 3 As shown, the adjustment assembly includes a first rod 4 slidably mounted on a mounting bracket, and two second rods 5 slidably mounted at both ends of the first rod 4. The first rod 4 extends along the width of the chassis, and the two second rods 5 located at the front end of the frame are respectively provided with headlight modules 200, and the two second rods 5 located at the rear end of the frame are respectively provided with taillight modules 300.

[0051] Specifically, the first rod 4 is slidably connected to the support rod 3 via a connecting sleeve 41 sleeved on the support rod 3, and the first rod 4 is fixedly connected to the connecting sleeve 41. Two second rods 5 are respectively inserted into the two ends of the first rod 4, so that the two second rods 5 are respectively extended and retracted along the length direction of the first rod 4, that is, along the width direction of the chassis, thereby realizing the adjustable position of the headlight module 200 and the taillight module 300 in the width direction of the chassis.

[0052] It is worth mentioning that, in this embodiment, the first rod 4 and the second rod 5 are preferably rectangular tubes with a cavity in the middle. The first rod 4 can be inserted into the cavity of the second rod 5, and the second rod 5 can also be inserted into the cavity of the first rod 4. In this way, the second rod 5 can be telescopically arranged relative to the first rod 4, so as to adjust the position of the headlight module 200 and the taillight module 300 in the width direction of the chassis.

[0053] It is understandable that, in addition to using rectangular tubes, the first rod 4 and the second rod 5 can also be long strip-shaped plates. In specific implementations, for example, a groove extending along the length of the first rod 4 can be provided on the first rod 4, and a slider embedded in the groove can be provided on the second rod 5. Through the sliding cooperation of the slider in the groove, the extension and retraction of the second rod 5 relative to the first rod 4 can also be achieved. Such a configuration is also acceptable.

[0054] See also Figure 2 and Figure 3 As shown, in this embodiment, based on the telescopic arrangement of the second rod 5 relative to the first rod 4, a first locking member 10 is provided between the first rod 4 and the mounting frame. The first locking member 10 is used to lock the first rod 4 onto the mounting frame. Furthermore, a second locking member 20 is provided between each second rod 5 and the first rod 4, and the second locking member 20 is used to lock the corresponding second rod 5 onto the first rod 4. In this way, the first locking member 10 ensures that the first rod 4 is well locked onto the mounting frame, guaranteeing that the first rod 4 remains well on the mounting frame after movement. The second locking member 20 ensures that the corresponding second rod 5 is well locked onto the first rod 4, guaranteeing that the second rod 5 remains well on the first rod 4 after movement.

[0055] In specific implementation, both the first locking member 10 and the second locking member 20 are preferably locking bolts. The locking bolts screwed into the threaded holes on the connecting sleeve 41 tighten the support rod 3, so that the first rod body 4 is better fixed on the support rod 3. The locking bolts screwed into the threaded holes on the first rod body 4 tighten the second rod body 5, so that the second rod body 5 is better fixed on the first rod body 4.

[0056] In another preferred embodiment, the mounting bracket includes a connecting base 2 connected to the vehicle frame and a first bracket connected to the connecting base 2. The first bracket is equipped with a first linear drive device that drives the adjustment component to move along the chassis height direction, and a guide structure is provided between the first bracket and the adjustment component to guide the movement of the adjustment component. By providing the first linear drive device, the movement of the adjustment component along the chassis height direction can be automated, thus automating the movement of the headlight module 200 and taillight module 300 relative to the mounting bracket in the chassis height direction. Furthermore, the guide structure improves the accuracy of the adjustment component's movement direction.

[0057] Specifically, the guide structure includes a guide rail disposed on one of the first bracket and the adjusting component, and a sliding block disposed on the other of the first bracket and the adjusting component. The sliding block is embedded and slides on the guide rail, and is connected to the power output end of the first linear drive device. The first linear drive device drives the sliding block to move along the guide rail, thereby causing the adjusting component to move along the height direction of the chassis.

[0058] In another preferred embodiment, the adjustment assembly includes a mounting plate slidably mounted on a first bracket, a first slide rod and a second slide rod slidably mounted on the mounting plate along the width direction of the chassis, and a second linear drive device that drives the first slide rod and the second slide rod to move synchronously in opposite directions. Two headlight modules 200 are respectively mounted on the first slide rod and the second slide rod, or two taillight modules 300 are respectively mounted on the first slide rod and the second slide rod.

[0059] In practice, a sliding block is provided on one side of the mounting plate. With the sliding cooperation between the sliding block and the guide rail, the mounting plate slides on the first bracket. A sliding groove is provided on the side of the mounting plate opposite to the sliding block. The first slide rod and the second slide rod are slidably disposed in the sliding groove. A second linear drive device is also provided on the mounting plate between the first slide rod and the second slide rod.

[0060] A second linear drive device drives the first and second sliding rods at both ends to move synchronously in opposite directions, causing them to move closer or further apart. This adjusts the spacing between the two headlight modules 200 or the two taillight modules 300 on the first and second sliding rods. The second linear drive device automates the movement of the headlight modules 200 and taillight modules 300 along the width of the chassis. Furthermore, in conjunction with the first linear drive device, it automates the adjustment of the headlight and taillight modules 200 positions, facilitating rapid adjustment of their positions.

[0061] It is worth noting that the first linear drive device in this embodiment can be, for example, a cylinder, a hydraulic cylinder, or a linear module. The second linear drive device can be, for example, a double-rod cylinder, with its two power output ends connected to the first slide rod and the second slide rod, respectively.

[0062] Furthermore, as a preferred embodiment, the length of the contouring chassis 1 in this embodiment is between 1000mm and 1200mm, the width is between 800mm and 1000mm, and the height is between 350mm and 400mm. These limitations on the length, width, and height of the contouring chassis 1 allow for miniaturization, making it easier to store in the trunk of the vehicle under test and carry it with the vehicle, thereby improving ease of use.

[0063] In specific implementation, the length of the contouring chassis 1 can be set to, for example, 1000mm, 1050mm, 1100mm, 1150mm or 1200mm, the width of the contouring chassis 1 can be set to, for example, 800mm, 850mm, 900mm, 950mm or 1000mm, and the height of the contouring chassis 1 can be set to, for example, 350mm, 370mm or 400mm.

[0064] The auxiliary device for adaptive headlight performance testing in this embodiment can perform performance testing on the adaptive headlights of a test vehicle without relying on an external target vehicle. This not only helps reduce manpower input and vehicle operating costs, but also improves testing efficiency, economy, and safety, and has a very good effect.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
