Description

Technical Field

[0001] The present invention relates to the technical field of zoom flashlight detection, and in particular to a zoom test device for an optical zoom flashlight. Background Art

[0002] The optical zoom flashlight achieves stepless switching between spotlight (long-range illumination) and floodlight (wide-range illumination) by adjusting the distance between the lens and the LED lamp beads.

[0003] Optical zoom flashlights are often used in underwater rescue scenarios, such as shallow water search and rescue and search and rescue in water-land junction areas. Optical zoom flashlights use zoom to quickly switch between focusing for signal positioning and flooding for surface lighting. However, during the zoom process, moist air or water can easily intrude into the threaded zoom area, even breaking through the O-ring of the flashlight and entering the interior of the flashlight, causing a short circuit in the flashlight or adhering to the lens inside the flashlight, affecting the subsequent normal use of the flashlight. It is difficult to reproduce the complex usage scenarios of zoom flashlights in shallow water and water-land junction areas, making it difficult for general sealing tests to meet usage requirements. In addition, during the focusing process of the optical zoom flashlight, the light spot changes in a large range, which requires a large spatial area during the light spot test of the optical zoom flashlight. At the same time, during the test of larger or smaller light spots, if there is a slight angle deviation or slight distortion at the edge of the light spot, it is difficult to measure, resulting in inaccurate test results. Therefore, a zoom test device for an optical zoom flashlight is proposed. Summary of the Invention

[0022] Example, see Figures 1 to 9 A zoom test device for an optical zoom flashlight comprises a test base 1 and a test chamber 2 for testing a zoom flashlight 3. The top of the test chamber 2 is connected to two electrically controlled guide rails 8 via an upper adjustment ring 4. The inner sidewall of the upper adjustment ring 4 is connected to a mounting assembly for limiting the position of the zoom flashlight 3. Two symmetrically arranged compensation rails 10 are provided below the mounting assembly. The compensation rails 10 are connected to a focusing clamp 12 via a hydraulic push rod 11. Furthermore, the top of the test chamber 2 is rotatably connected to the adjusting upper ring 4, and the bottom end of the test chamber 2 is rotatably connected to the adjusting lower ring 9. The two ends of the electric control guide rail 8 are respectively fixedly connected to the adjusting upper ring 4 and the adjusting lower ring 9. The mounting assembly consists of a mounting ring 5 and a plurality of limit pressure plates 6. The mounting ring 5 is rotatably connected to the inner wall of the adjusting upper ring 4, and the outer side wall of the bottom end of the mounting ring 5 is rotatably connected to the plurality of limit pressure plates 6 through a plurality of pins. A torsion spring is sleeved on the pin. The non-limiting part of the limit pressure plate 6 and the top of the test chamber 2 are both made of magnet material. The bottom end of the mounting ring 5 is respectively fixedly connected to two symmetrically arranged moving seats 7, and the moving seat 7 is slidably connected to the electric control guide rail 8. The inner wall of the test chamber 2 is fixedly connected to the compensation slide rail 10. The inner wall of the compensation slide rail 10 is slidably connected to the hydraulic push rod 11 through a limit slider, and the output end of the hydraulic push rod 11 is fixedly connected to the focusing clamp 12; During the subsequent resetting process, the limit pressure plate 6 will be expanded due to magnetic attraction on the test chamber 2; It should be noted that: the head of the zoom flashlight 3 is placed on the mounting ring 5, and then the zoom flashlight 3 is pushed downward, so that the mounting ring 5 slides downward and disengages from the upper adjustment ring 4. After the mounting ring 5 is disengaged from the upper adjustment ring 4, the limiting pressure plate 6 will flip upward under the action of the torsion spring, so that multiple limiting pressure plates 6 clamp and limit the head of the zoom flashlight 3. The synchronous and uniform clamping of multiple limiting pressure plates 6 will correct the vertical position of the zoom flashlight 3 to ensure that the zoom flashlight 3 remains in a vertical state. Subsequently, the sliding of the movable seat 7 in the electric control guide rail 8 is controlled to stop and limit at the bottom, so that the zoom flashlight 3 slides into the test chamber 2, and then the focusing clamping plate 12 is driven to move by the hydraulic push rod 11 to fix the outer wall of the zoom flashlight 3. The above advantages are as follows: the mounting assembly can be used in conjunction with the focusing clamp 12 to achieve separate position limits on the head and outer wall of the zoom flashlight 3, facilitating subsequent automatic zoom operation in the test chamber 2, making the testing of the zoom flashlight 3 more standardized and efficient; The test base 1 is fixedly connected to the test chamber 2 via multiple transition rings 13. The upper transition ring 13 is fixedly assembled to the outer wall of the bottom end of the test chamber 2. The inner wall of the middle transition ring 13 is connected to a control component for adjusting the light spot size of the zoom flashlight 3. Furthermore, the control assembly includes an adjustment convex mirror 15 and an adjustment concave mirror 16 disposed within the transition ring 13. The inner sidewall of the transition ring 13 located in the middle is fixedly connected to two symmetrically arranged control swivels 14. The two control swivels 14 are rotatably connected to the adjustment convex mirror 15 and the adjustment concave mirror 16, respectively. It should be noted that: when the zoom flashlight 3 is tested, the started zoom flashlight 3 will illuminate the light spot on the photosensitive arc plate 31 on the measuring platform 30. The photosensitive arc plate 31 is provided with a plurality of photoelectric sensors for sensing the range and intensity of the light spot. During this process, the upper adjustment ring 4 and the lower adjustment ring 9 are controlled to rotate synchronously, thereby driving the two electrically controlled guide rails 8 to rotate, so that the head of the zoom flashlight 3 rotates, and the outer side wall of the zoom flashlight 3 fixed by the focusing clamp 12 will rotate with the head to realize the zoom operation. During the rotation, the focusing clamp 12 slides between the limiting slider and the compensation slide rail 10 to realize the distance compensation caused by the thread rotation during the zooming process of the zoom flashlight 3, thereby ensuring that the head of the zoom flashlight 3 does not rotate or move, and ensuring the light before and after zooming. The spot change is not affected by this process. When the zoom flashlight 3 is zoomed to the floodlight mode, the control seat 14 is used to keep the adjustment convex mirror 15 horizontal. Then, the light at a large angle will be abnormally refracted by the adjustment convex mirror 15, and the light spot will be split into multiple focal points, forming a light ring. Subsequently, the light ring is measured by the photosensitive arc plate 31 on the measurement platform 30, thereby realizing the reduction detection of the large light spot in the floodlight mode, reducing the entire detection space, and making the detection of the quantitatively reduced light spot in the floodlight mode more accurate. When the zoom flashlight 3 is zoomed to the spotlight mode, the control seat 14 is used to rotate the adjustment convex mirror 15 downward, and another control seat 14 is used to rotate the adjustment concave mirror 16 to a horizontal state. Then, the adjustment concave mirror 16 located in the light spot convergence area will expand the light spot, so that the small light spot in the spotlight mode can be magnified and detected. The above advantages are as follows: by using the adjustable convex mirror 15 and the adjustable concave mirror 16 in combination, the light spot of the zoom flashlight 3 in the floodlight mode can be reduced for detection, and the light spot in the spotlight mode can be magnified for detection, so that the light spot size is kept within a certain range, which greatly reduces the test space and makes the detection more accurate. The inner wall of the transition ring 13 at the bottom is connected to an annular liquid injection chamber 23, which is connected to two symmetrically arranged mist dispersion components. The inner end surface of the test seat 1 is connected to a measurement platform 30 through a planetary gear assembly. The measurement platform 30 is connected to multiple staggered photosensitive arc plates 31. Multiple simulated impellers 29 are installed on the outer side of the measurement platform 30. Furthermore, the mist dispersion component includes a mist dispersion chamber 18 arranged on the inner wall of the annular liquid injection chamber 23, and the top of the mist dispersion chamber 18 is connected to multiple mist dispersion buckets 19 through multiple connecting pipes 22. The inner end surface of the mist dispersion bucket 19 is fixedly connected to a one-way flow blocking plug 21 through a telescopic rod 20. The diameter of the one-way flow blocking plug 21 is slightly larger than the inner diameter of the bottom end of the mist dispersion bucket 19. The transition ring 13 at the bottom is connected to a booster pipe 17 for connecting to an external water pump. The booster pipe 17 is connected to the annular liquid injection chamber 23 and the mist dispersion chamber 18 through different control valves. The inner wall of the test seat 1 is respectively provided with a discharge groove 24 and two symmetrical A ventilation groove is provided, and a brushless fan 25 is provided at the outer end of the ventilation groove. The discharge groove 24 and the two ventilation grooves are provided with valves for controlling the opening and closing of the groove. The planetary gear assembly consists of a main drive gear 27 and a plurality of driven gears 28. The main drive gear 27 and the driven gear 28 are both rotatably connected to the inner end surface of the test seat 1. The main drive gear 27 is respectively engaged with the plurality of driven gears 28. The driven gear 28 is fixedly connected to the simulation impeller 29. The main drive gear 27 is fixedly connected to the measurement platform 30. The inner side wall of the test seat 1 is fixedly connected to an edge photosensitive ring 26, and a plurality of photosensitive arc plates 31 are arranged in a state of gradually spreading from the axis to the edge; The one-way flow structure of the one-way flow blocking plug 21 and the mist dispersion bucket 19 is set to prevent the mist dispersion bucket 19 from being continuously pressed and the water from entering the mist dispersion chamber 18 when water is subsequently injected.

[0023] It should be noted that: when it is necessary to simulate the use scenario of the zoom flashlight 3, the boost pipe 17 is connected to the external water pump, and water is pumped into the boost pipe 17. The boost pipe 17 is first connected to the mist dispersion chamber 18. After the water flows into the mist dispersion chamber 18, it presses the one-way flow blocking plug 21 through the connecting pipe 22, so that the channel between the connecting pipe 22 and the mist dispersion bucket 19 is opened, allowing the water flow to enter the mist dispersion bucket 19 and be squeezed out in the form of mist under high pressure. A salt block bag is set in the mist dispersion chamber 18 to make the water mist have a certain During this process, the brushless fan 25 is started to generate airflow in the test seat 1. The extruded water mist is diffused into the test chamber 2 through the transition ring 13 under the action of the airflow, so that the zoom flashlight 3 is in a continuously flowing high-humidity air environment. During this process, the zoom flashlight 3 is zoomed multiple times to simulate the high-humidity environment in which the zoom flashlight 3 is used during surface support. Then, the passage between the brushless fan 25 and the mist dispersion chamber 18 is closed, and the pressurized pipe 17 is connected to the annular liquid injection chamber 23. Water is continuously injected into the test seat 1 to simulate the state of the zoom flashlight 3 being used from the water surface into the water, and the changes in the light spot during this process are observed. Then, water is continuously injected to allow the water flow to completely submerge the zoom flashlight 3, and a zoom operation is performed in the water at certain intervals to simulate the state of the zoom flashlight 3 being used in the water. The zoom flashlight 3 is continuously tested for zooming in each simulated state, so that the test state is more in line with the state of the zoom flashlight 3 being used in water rescue. During the test, the main drive gear 27 is driven to rotate. The rotation of the main drive gear 27 drives the multiple driven gears 28 on the outside to rotate, so that the multiple simulated impellers 29 rotate in the water, simulating the state of the zoom flashlight 3 immersed in the water in a fluctuating and changing water area. At the same time, the multiple photosensitive arc plates 31 on the measuring platform 30 rotate with the main drive gear 27, so that the photosensitive arc plates 31 detect the edge and center position of the light spot of the zoom flashlight 3 during the rotation process, dynamically detecting the overall state of the light spot, and facilitating the rapid detection of whether the light spot is offset or distorted. The above advantages are as follows: the coordination changes of the mist dispersion chamber 18 and the annular liquid injection chamber 23 can be used to simulate various usage scenarios of the zoom flashlight 3 in water rescue. The changes in the light spot of the zoom flashlight 3 under the continuous zoom state during the test process can be used to determine whether the zoom use of the zoom flashlight 3 in each simulated state is abnormal. The multiple photosensitive arc plates 31 dynamically detect the overall state of the light spot, making the detection more efficient and accurate. When the present invention is in use, the head of the zoom flashlight 3 is placed on the mounting ring 5, and then the zoom flashlight 3 is pushed downward, so that the mounting ring 5 slides downward and disengages from the upper adjustment ring 4. After the mounting ring 5 is disengaged from the upper adjustment ring 4, the limiting pressure plate 6 will flip upward under the action of the torsion spring, so that multiple limiting pressure plates 6 clamp and limit the head of the zoom flashlight 3. The synchronous and uniform clamping of multiple limiting pressure plates 6 will correct the vertical position of the zoom flashlight 3, ensuring that the zoom flashlight 3 remains in a vertical state. Subsequently, the movable seat 7 is controlled to slide within the electrically controlled guide rail 8 to the bottom, where it stops and is limited, so that the zoom flashlight 3 slides into the test chamber 2. Then, the hydraulic push rod 11 drives the focusing clamp 12 to move, thereby clamping and limiting the outer wall of the zoom flashlight 3. In this way, the mounting assembly can be used in conjunction with the focusing clamp 12 to achieve separate positioning of the head and outer wall of the zoom flashlight 3, facilitating subsequent automatic zoom operation within the test chamber 2, making the detection of the zoom flashlight 3 more standardized and efficient. When testing the zoom flashlight 3, the started zoom flashlight 3 will illuminate the light spot on the photosensitive arc plate 31 on the measuring platform 30. The photosensitive arc plate 31 is provided with a plurality of photoelectric sensors for sensing the range and intensity of the light spot. During this process, the upper adjustment ring 4 and the lower adjustment ring 9 are controlled to rotate synchronously, thereby driving the two electrically controlled guide rails 8 to rotate, so that the head of the zoom flashlight 3 rotates, and the outer side wall of the zoom flashlight 3 fixed by the focusing clamp 12 will rotate with the head to realize the zoom operation. During the rotation, the focusing clamp 12 slides between the limiting slider and the compensation slide rail 10 to realize the distance compensation caused by the rotation of the thread during the zooming process of the zoom flashlight 3, ensuring that the head of the zoom flashlight 3 does not rotate or move, and ensuring that the change of the light spot before and after the zoom is not affected by this process. When the zoom flashlight 3 is zoomed to the floodlight mode, the control seat 14 is used to keep the adjustment convex mirror 15 level, then the large angle The light of small degrees will be abnormally refracted by the adjusting convex mirror 15, and the light spot will be split into multiple focal points, and a light ring will appear. Subsequently, the light ring is measured by the photosensitive arc plate 31 on the measuring platform 30, so as to realize the reduction detection of the large light spot in the floodlight mode, so that the entire detection space is reduced, and the detection of the light spot after quantitative reduction in the floodlight mode is more accurate. When the zoom flashlight 3 is zoomed to the focusing mode, the adjusting convex mirror 15 is rotated downward by the control rotating seat 14, and the adjusting concave mirror 16 is rotated to a horizontal state by another control rotating seat 14, then the adjusting concave mirror 16 located in the light spot convergence area will enlarge the light spot, so that the small light spot in the focusing mode is magnified for detection. In this way, the convex mirror 15 and the concave mirror 16 can be used in conjunction to reduce the light spot of the zoom flashlight 3 in the floodlight mode for detection, and enlarge the light spot in the focusing mode for detection, so that the light spot is kept within a certain range of size, which greatly reduces the test space and makes the detection more accurate. When it is necessary to simulate the usage scenario of the zoom flashlight 3, the boost pipe 17 is connected to the external water pump, and water is pumped into the boost pipe 17. The boost pipe 17 is first connected to the mist dispersion chamber 18. After the water flows into the mist dispersion chamber 18, it will press the one-way flow blocking plug 21 through the connecting pipe 22, so that the channel between the connecting pipe 22 and the mist dispersion bucket 19 is opened, allowing the water flow to enter the mist dispersion bucket 19 and be squeezed out in the form of mist under high pressure. A salt block bag is set in the mist dispersion chamber 18 to make the water mist have a certain corrosiveness. During this process, the brushless fan 25 is started to generate airflow in the test seat 1, and the squeezed water mist is under the effect of the airflow. Under the condition of high humidity, the water is diffused into the test chamber 2 through the transition ring 13, so that the zoom flashlight 3 is in a continuously flowing high-humidity air environment. During this process, the zoom flashlight 3 is zoomed multiple times to simulate the high-humidity environment in which the zoom flashlight 3 is used during surface support. Then, the brushless fan 25 and the passage between the mist dispersion chamber 18 are closed, and the boost pipe 17 is connected to the annular liquid injection chamber 23, so that water is continuously injected into the test seat 1, simulating the state of the zoom flashlight 3 being used from the water surface into the water. The changes in the light spot during this process are observed, and then water is continuously injected to allow the water flow to completely submerge the zoom flashlight 3. , and zoom operations are performed at certain intervals in the water to simulate the use state of the zoom flashlight 3 in the water, so that the zoom flashlight 3 performs continuous zoom tests in each simulation state, making the test state more consistent with the use state of the zoom flashlight 3 in water rescue. During the test, the main drive gear 27 is driven to rotate, and the rotation of the main drive gear 27 will drive the multiple driven gears 28 on the outside to rotate, so that the multiple simulated impellers 29 rotate in the water, simulating the state of the zoom flashlight 3 immersed in the water in a fluctuating water area. At the same time, the multiple photosensitive arc plates 31 on the measuring platform 30 will rotate along with the main drive gear 27. The rotation allows the photosensitive arc plate 31 to detect the edge and center position of the light spot of the zoom flashlight 3 during the rotation, and dynamically detect the overall state of the light spot, so as to quickly detect whether the light spot is offset or distorted. In this way, the coordinated changes of the fog dispersion chamber 18 and the annular liquid injection chamber 23 can be used to simulate various usage scenarios of the zoom flashlight 3 in water rescue. By measuring the changes in the light spot of the zoom flashlight 3 under the continuous zoom state during the test, it is determined whether the zoom use of the zoom flashlight 3 in each simulated state is abnormal. Multiple photosensitive arc plates 31 dynamically detect the overall state of the light spot, making the detection more efficient and accurate.
