Description

Technical Field

[0001] This invention relates to the field of vehicle collision testing, and more specifically to a collision lighting system with a rotatable lamp head. Background Technology

[0002] During car crash tests, the entire collision process requires high-speed cameras to capture the footage for later image analysis. In car crash tests, high-speed cameras typically operate at a shooting frequency of 1000 FPS, with extremely short exposure times for each image. To ensure optimal image quality, the ambient light intensity (50,000 LUX-100,000 LUX) needs to be increased to guarantee good image quality.

[0003] The challenges in designing the lighting system are as follows: 1. Different test types and samples require different lighting heights and angles, necessitating frequent movement and positioning of the light fixtures. Existing lighting systems typically use electric hoists for fixing, lacking the ability to record test positions or provide precise positioning. 2. Frontal and rear collision tests illuminate the left and right sides of the vehicle, while side collision tests illuminate the front, rear, and doors. To meet filming requirements, existing lighting systems often employ a four-light fixture design, with two fixtures specifically for supplemental lighting on the door sides. However, this design significantly increases the complexity and cost of the entire light fixture design, resulting in a substantial increase in the weight of the fixture and consequently, a sharp increase in the load-bearing requirements and costs of the laboratory's roof structure. 3. Existing light fixture designs often use a lower fixture fixed to an upper fixture. To ensure structural strength, the upper fixture needs to be sufficiently strong and heavy to support the weight of the lower fixture, which also increases the load-bearing requirements of the roof. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a collision lighting system with a rotatable lamp head, which can solve the problem that the existing lighting system does not have the function of recording the test position or accurately positioning, and can also solve the problem that the existing lighting system often uses 4 lamp holders, which increases the complexity of the entire lamp holder design and greatly increases the cost.

[0005] This application provides a collision lighting system with rotatable lamp heads, comprising: a walking mechanism and a lamp holder assembly. The walking mechanism includes a first track and a second track, which are parallel to each other. Multiple drive trolleys are mounted on both the first and second tracks. Laser displacement sensors for detecting the displacement of the drive trolleys are mounted at both ends of the first track. The lamp holder assembly includes an upper lamp holder and a lower lamp holder. The upper lamp holder is connected to the track via drive trolleys. Multiple lamp heads are mounted on the bottom of the lower lamp holder. Multiple steel cables connect the lower lamp holder and the upper lamp holder for suspending the lower lamp holder at the lower end of the upper lamp holder.

[0006] In some embodiments, four limiting devices are installed on the second track, with one limiting device installed at each end of the second track and two limiting devices installed in the middle of the second track.

[0007] In some embodiments, the upper lamp holder includes an upper lamp holder frame, two lifting assemblies, two first lifting rings, and two second lifting rings. The upper lamp holder frame is a frame structure. A first lifting ring is provided on one set of opposite corners of the upper lamp holder frame, and a second lifting ring is provided on the other set of opposite corners of the upper lamp holder frame. The lifting assemblies are installed in the middle of the upper lamp holder frame.

[0008] In some embodiments, the upper lamp holder frame includes two parallel long poles, three first short poles and two second short poles are spaced apart between the two long poles, the second short poles are located at both ends of the long poles, the first short poles are parallel to each other and perpendicular to the long poles, and the lifting assembly is installed between two adjacent first short poles.

[0009] In some embodiments, the lifting assembly includes a drive motor, a worm gear reducer, and a cable drum, wherein the worm gear reducer is connected to the drive motor, the cable drum is connected to the worm gear reducer, and the cable drum and the worm gear reducer are equipped with rotary encoders.

[0010] In some embodiments, the first lifting ring is welded to the upper lamp holder frame, and the upper end of the first lifting ring is connected to the drive trolley, and the lower end of the first lifting ring is equipped with a first fixed pulley; the second lifting ring is welded to the upper lamp holder frame, and the upper end of the second lifting ring is connected to the drive trolley, and the lower end of the second lifting ring is equipped with a second fixed pulley.

[0011] In some embodiments, both ends of the first short rod located in the middle are equipped with first rollers; the front ends of the other two first short rods are equipped with third and fourth fixed pulleys, and the rear ends of the other two first short rods are equipped with second and third rollers. The distribution order of the above devices on the long rod is as follows: first fixed pulley, third fixed pulley, fourth fixed pulley, first roller, second roller, third roller, second fixed pulley; a fifth fixed pulley is equipped at the end of the second short rod adjacent to the first fixed pulley.

[0012] In some embodiments, the lower lamp holder includes a lower lamp holder frame, which is a bracket-shaped frame structure that is horizontal in the middle and inclined to the same side at both ends. The lower lamp holder frame is equipped with a plurality of third lifting rings and a plurality of fourth lifting rings. The third lifting rings correspond one-to-one with the positions of the first fixed pulleys, and the third lifting rings are connected to the first fixed pulleys by the steel cables. The fourth lifting rings correspond one-to-one with the positions of the second fixed pulleys, and the fourth lifting rings are connected to the second fixed pulleys by the steel cables.

[0013] In some embodiments, a plurality of fixed frames are installed in the horizontal structure in the middle of the lower lamp holder frame. The fixed frames are frame-shaped structures and the fixed frames together form a grid-like structure. In the inclined structures on both sides of the lower lamp holder frame, a plurality of fixed frames and three rotating frames are installed.

One end of the tank chain is connected to the cable trough, and the other end is connected to a junction box outside the lighting system.

[0015] The beneficial effects provided by this invention include:

[0016] 1. This application uses a control system composed of a three-phase asynchronous motor and a high-precision displacement encoder to complete the movement and positioning of the lamp holder, which ensures precise control of the test position and movement process. The displacement control accuracy can reach ±2mm, which is much better than the traditional electric hoist-type lamp holder control method.

[0017] 2. This application adopts a bracket shape and a rotatable light, and only 2 sets of light stands are needed to meet the test requirements of frontal collision and side collision, which greatly reduces the design and manufacturing cost of the light stands. At the same time, the overall weight is controlled within 3 tons, and the overall weight is expected to be 50% of the traditional 4 sets of light stands, which greatly reduces the laboratory infrastructure cost.

[0018] 3. Through ingenious design, the weight of the lower light frame is directly loaded onto the hanging rings that fix the upper light frame. Furthermore, the steel cable arrangement ensures that the lower light frame exerts only a downward force on the upper light frame, greatly reducing the design strength and weight of the upper light frame. This ensures safety from a design perspective and reduces the design cost of the laboratory roof load-bearing structure. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] This application provides a collision lighting system with a rotatable lamp head, including a traveling mechanism and a lamp holder assembly. The traveling mechanism includes a first track 101 and a second track 102, which are parallel to each other. Multiple drive trolleys 8 are mounted on both tracks 101 and 102. Laser displacement sensors 6 are installed at both ends of the first track 101 to detect the displacement of the drive trolleys 8. The desired position of the drive trolleys 8 is selected in the control system connected to the traveling mechanism, and the laser displacement sensors 6 allow the drive trolleys 8 to be precisely moved to the designated position. The first track 101 and the second track 102 are made of 16-meter 20#A I-beams. The drive trolleys 8 are Brima SWL 500 models, and the laser displacement sensors 6 are Keyence TB5000 models.

[0028] As an optional embodiment, see [link to example]. Figure 2 As shown, four limiting devices 7 are installed on the second track 102. One limiting device 7 is installed at each end of the second track 102, and two limiting devices 7 are installed in the middle of the second track 102. Each limiting device 7 consists of an electronic limit switch and a mechanical stop. When the drive trolley 8 moves on the second track 102, if it touches the electronic limit switch, the drive trolley 8 stops moving. If the electronic limit switch of the limiting device 7 fails, and the drive trolley 8 continues to move, it will touch the mechanical stop, forcibly stopping the drive trolley 8 and protecting the lighting system.

[0029] The lamp holder assembly includes an upper lamp holder 2 and a lower lamp holder 3. The upper lamp holder 2 is connected to the first track 101 and the second track 102 via a drive trolley 8. Multiple lamp heads 4 are installed at the bottom of the lower lamp holder 3, and multiple steel cables 5 are provided between the lower lamp holder 3 and the upper lamp holder 2 to suspend the lower lamp holder 3 at the lower end of the upper lamp holder 2. The steel cables 5 are stainless steel anti-rotation cables with a diameter of 5mm. Since the lower lamp holder 3 is connected to the upper lamp holder 2 via the steel cables 5, the force transmitted from the lower lamp holder 3 to the upper lamp holder 2 is only a vertical downward tension, which greatly reduces the design strength and weight of the upper lamp holder 2. From a design perspective, this structure reduces the load-bearing design cost of the laboratory roof.

[0030] As an optional embodiment, see [link to example]. Figure 3As shown, the upper lamp holder 2 includes an upper lamp holder frame 11, two lifting assemblies, two first lifting rings 901, and two second lifting rings 902. The upper lamp holder frame 11 is a frame structure with dimensions of 1.8m × 4.2m, and is welded from 100mm × 100mm 6061T6 aluminum tubing with a wall thickness of 5mm, mainly used to support the drive system. A first lifting ring 901 is provided on one set of opposite corners of the upper lamp holder frame 11, and a second lifting ring 902 is provided on the other set of opposite corners. The lifting assemblies are installed in the middle of the upper lamp holder frame 11. The first lifting rings 901 and second lifting rings 902 are connected to the drive trolley 8, so that when the drive trolley 8 moves on the first track 101 and the second track 102, it can move the upper lamp holder 2 together, and simultaneously move the lower lamp holder 3. Furthermore, the limiting device 7 not only limits the movement distance of the drive trolley 8 but also limits the movement distance of the lamp holder assembly.

[0031] As an optional embodiment, see [link to example]. Figure 3 and Figure 4 As shown, the upper lamp holder frame 11 includes two parallel long rods 10. Three first short rods 231 and two second short rods 232 are spaced apart between the two long rods 10. The second short rods 232 are located at both ends of the long rods 10. The first short rods 231 are parallel to each other and perpendicular to the long rods 10. A lifting assembly is installed between two adjacent first short rods 231. The steel cable 5 passes through the lifting assembly and is connected to the lower lamp holder 3, so that the lamp holder 3 can be raised or lowered by raising and lowering the steel cable 5 through the lifting assembly.

[0032] As an optional embodiment, see [link to example]. Figure 3 As shown, the lifting assembly includes a drive motor 15, a worm gear reducer 14, and a cable drum 12. The worm gear reducer 14 is connected to the drive motor 15, and the cable drum 12 is connected to the worm gear reducer 14. A rotary encoder 13 is installed on both the cable drum 12 and the worm gear reducer 14. The speed ratio of the worm gear reducer 14 is 10. The drive motor 15 rotates first, and after being reduced in speed by the worm gear reducer 14, it drives the cable drum 12 to rotate. The cable drum 12 then drives the cable 5 to be wound up and down, thereby achieving height adjustment of the lower lamp holder 3. The rotary encoder 13 is coaxially mounted with the worm gear reducer 14, providing a measurement signal. A high-precision value (0.2mm step) is obtained by calculating the value of 2000 pulses per revolution, allowing for real-time measurement of the position of the lower lamp holder 3.

[0033] As an optional embodiment, see [link to example]. Figure 3As shown, the first lifting ring 901 is welded to the upper lamp holder frame 11, and the upper end of the first lifting ring 901 is connected to the drive trolley 8. The lower end of the first lifting ring 901 is equipped with a first fixed pulley 171. The second lifting ring 902 is welded to the upper lamp holder frame 11, and the upper end of the second lifting ring 902 is connected to the drive trolley 8. The lower end of the second lifting ring 902 is equipped with a second fixed pulley 172. The first fixed pulley 171 and the second fixed pulley 172 are directly connected to the lower lamp holder 3 through the steel cable 5, so that the weight of the lower lamp holder 3 is directly borne by the first track 101 and the second track 102, reducing the weight that the upper lamp holder 2 needs to bear.

[0034] As an optional embodiment, see [link to example]. Figure 4 As shown, the first short rod 231 in the middle is equipped with first rollers 20 at both ends; the front ends of the other two first short rods 231 are equipped with third fixed pulleys 18 and fourth fixed pulleys 19, and the rear ends of the other two first short rods 231 are equipped with second rollers 21 and third rollers 22. The above devices are distributed on the long rod 10 in the following order: first fixed pulley 171, third fixed pulley 18, fourth fixed pulley 19, first roller 20, second roller 21, third roller 22, second fixed pulley 172; the end of the second short rod 232 adjacent to the first fixed pulley 171 is equipped with a fifth fixed pulley 16. After the steel cable 5 is wound around the steel cable drum 12, both ends of the steel cable 5 are extended. The winding sequence of one end is: third fixed pulley 18 - fifth fixed pulley 16 - fourth fixed pulley 19 - first fixed pulley 171 - third lifting ring 251 of the lower lamp holder 2; the winding sequence of the other end of the steel cable 5 is: first roller 20 - second roller 21 - third roller 22 - second fixed pulley 172 - fourth lifting ring 252 of the lower lamp holder 2. A single lamp holder assembly is suspended by two steel cables 5, and one steel cable 5 is controlled by a lifting assembly. The rotation of the drive motor 15 of the lifting assembly drives the winding or releasing of the steel cable 5, thereby realizing the overall or unilateral height control of the lower lamp holder 3.

[0035] As an optional embodiment, see [link to example]. Figure 5 As shown, the lower lamp holder includes a lower lamp holder frame 29, which is a bracket-shaped frame structure that is horizontal in the middle and inclined to the same side at both ends. The lower lamp holder frame 29 has dimensions of 1.7m × 7m and is welded from 100mm × 100mm 6061T6 aluminum tubes with a wall thickness of 5mm. The horizontal part in the middle of the lower lamp holder frame 29 has a length of 5m, and 5 sets of lamp heads 4 are arranged along the long side in the middle, with 3 lamp heads in each set. The angle of the inclined surface of the lower lamp holder frame 29 relative to the corner of the horizontal structure in the middle is 30°, and the length of the inclined surface is 1.2m. 1 set of 3 lamp heads 4 are arranged on each inclined surface.

[0036] The lower lamp holder frame 29 is equipped with multiple third lifting rings 251 and multiple fourth lifting rings 252. The third lifting rings 251 correspond one-to-one with the first fixed pulleys 171, and are connected to each other by steel cables 5. The fourth lifting rings 252 correspond one-to-one with the second fixed pulleys 172, and are connected to each other by steel cables 5. After connecting the upper lamp holder 2 and the lower lamp holder 3, both ends of each steel cable 5 are vertical, ensuring that the force transmitted from the lower lamp holder 3 to the traveling mechanism is only vertical, with no horizontal component. This reduces the force received by the traveling mechanism, lessens equipment wear, and increases the lifespan of the lighting system.

[0037] As an optional embodiment, see [link to example]. Figure 5 As shown, multiple fixing brackets 27 are installed in the horizontal structure in the middle of the lower lamp holder frame 29. The fixing brackets 27 are frame-shaped structures, and the fixing brackets 27 enclose to form a grid structure. The lamp head 4 installed in the middle of the lower lamp holder frame 29 is fixed to the two short sides of the fixing brackets 27 by bolts. When the bolts are loosened, the lamp head 4 can rotate. The central axis of its rotation is parallel to the long side of the fixing bracket 27. When the lamp head 4 rotates to the designated position, the bolts are tightened to fix the lamp head 4 in the current position.

[0038] In the inclined structure on both sides of the lower lamp holder frame 29, multiple fixed frames 27 and three rotating frames 28 are installed. The rotating frames 28 are installed in the inclined structure along the short side of the lower lamp holder frame 29, and a fixed frame 27 is provided on each side of the rotating frame 28. The lamp head 4 installed on the inclined surface is fixed by the fixed frame 27 and the rotating frame 28. The lamp head 4 is fixed to the two sides of the rotating frame 28 adjacent to the fixed frame 27 by bolts. When the bolts are loosened, the lamp head 4 can rotate. Its rotation axis is parallel to the short side of the fixed frame 27. When the lamp head 4 rotates to the designated position, the bolts are tightened to fix the lamp head 4 in the current position. When the rotating frame 28 is connected to the fixed frame 27 by bolts, when the bolts between the rotating frame 28 and the fixed frame 27 are loosened, the entire rotating frame 28 can rotate. The rotation axis is parallel to the long side of the fixed frame 27, thereby realizing the purpose of bidirectional rotation of the lamp head 4, and further meeting the requirements of supplementary lighting at the door position in the side collision test.

[0039] As an optional embodiment, see [link to example]. Figure 5 As shown, a cable fixing device is provided at the top of the lower lamp holder frame 29. The cable fixing device includes a tank chain 26 and a cable trough 24. The cable trough 24 is installed at the top of the lower lamp holder frame 29. One end of the tank chain 26 is connected to the cable trough 24, and the other end is connected to the junction box outside the lighting system. The tank chain 26 has dimensions of 65mm × 200mm and a length of 10m.

[0040] This application provides a collision lighting system with a rotatable lamp head, the specific implementation of which is as follows:

[0041] During the frontal collision test of the test vehicle, the required position of the lamp assembly is selected in the external control system according to the vehicle size and test requirements. Clicking "Move Lamp Assembly" moves the lamp assembly to the designated test position through the cooperation of the drive trolley 8 and the laser displacement sensor 6. Then, the drive motor 15 is activated, rotating the steel cable roller 12 to move the steel cable 5 downwards until the height of both sides of the lower lamp assembly 3 reaches the test requirements. The movement of the lamp assembly then stops. Throughout the process, the control system displays the position of the lamp assembly on the traveling mechanism, the height of the lower lamp assembly 3, and the tilt angle of the lower lamp assembly 3 in real time. After the lamp assembly is adjusted to the target position, the lamp heads 4 at the front and rear inclined surfaces have the same angle as the five sets of lamp heads 4 in the middle, used to supplement the left and right sides of the frontal collision vehicle for the test vehicle's frontal collision test. After the frontal collision test, clicking the 0 button in the control system causes the lower lamp assembly 3 to rise until it returns to its initial height position. The lamp assembly then moves on the traveling mechanism until it returns to its initial position.

[0042] When conducting a side-impact test on a test vehicle, the required position of the lamp assembly is selected in the external control system according to the vehicle size and test requirements. The lamp assembly is then moved using the drive trolley 8 and laser displacement sensor 6. The drive motor 15 is then activated, rotating the steel cable roller 12 to move the steel cable 5 downwards until the height of both sides of the lower lamp assembly 3 meets the test requirements. The movement of the lamp assembly then stops. Throughout the process, the control system displays the position of the lamp assembly on the traveling mechanism, the height of the lower lamp assembly 3, and the tilt angle of the lower lamp assembly 3 in real time. The position of the lamp head 4 is adjusted; at this point, the height of the lower lamp assembly 3 is approximately 3 meters. The tester records this height and then lowers the lower lamp assembly 3 to a position of 1.5 meters using a manual remote control. The fixing bolts of the lamp head 4 on the inclined surface are loosened, the lamp head 4 is rotated to the side-impact test angle, and the bolts are tightened. The lower lamp assembly 3 is then raised to the previously recorded test height using a manual remote control. At this point, the lighting system meets the side-impact test requirements, and the side-impact test of the test vehicle is conducted. After the side impact test is completed, click the 0 button in the control system. The lower lamp holder 3 will start to rise until it returns to the initial height position. Then the lamp holder assembly will move on the traveling mechanism until it returns to the initial position.
