Description

Technical Field

[0001] This utility model relates to the field of laser ranging technology, and in particular to a laser ranging machine testing device. Background Technology

[0002] A laser rangefinder is a device that uses laser pulses to measure distances. Its working principle involves emitting high-energy laser pulses towards a target object and receiving the reflected laser signal. The distance between the target object and the ranging system is determined by calculating the propagation time of the laser signal. Because the speed of light is constant, laser rangefinders can achieve high-precision distance measurements and are widely used in military, surveying, and industrial fields.

[0003] Environmental testing is a crucial step in the production of laser rangefinders. It is mainly used to detect the working status of laser rangefinders under specific environmental conditions to ensure their reliability and stability in practical applications. However, since the ranging range of laser rangefinders can usually reach several kilometers, it is difficult to directly test their maximum ranging performance in the actual production environment. Therefore, the method of detecting the energy value of the emitted light pulse of the laser rangefinder is usually used to indirectly evaluate its working status.

[0004] Currently, environmental testing of laser rangefinders typically involves mounting a single test sample on a test platform within an environmental test chamber. The rangefinder's lens is then aligned with the chamber's light-transmitting window, allowing the emitted laser pulse to pass through the window and be received and measured by an external energy meter. However, this testing method has significant limitations: firstly, a single environmental test can usually only test a small number of rangefinders, resulting in low testing efficiency; secondly, environmental testing consumes a large amount of energy and manpower, leading to high production costs; and finally, this inefficient testing method severely restricts the mass production progress of laser rangefinders, making it difficult to meet the production needs of cost reduction and efficiency improvement.

[0034] A laser range finder is a device that uses laser pulses to measure distance. Its working principle is to emit high-energy laser pulses to the target object through a laser pulse transmitter and receive the laser signals reflected by the target object. By calculating the propagation time of the laser signals, the distance between the target object and the range finding system can be determined. Since the speed of light is constant, laser range finders can achieve high-precision distance measurement and are widely used in military, surveying, and industrial fields.

[0035] During the production of laser range finders, environmental testing is a crucial step. Environmental testing is mainly used to detect the working state of laser range finders under specific environmental conditions to ensure their reliability and stability in actual applications. However, since the ranging range of laser range finders can usually reach several kilometers, it is difficult to directly test their maximum ranging performance in the actual production environment. Therefore, the method of detecting the energy value of the emitted light pulse is usually used to indirectly evaluate the working state of the laser range finder.

[0036] Currently, environmental testing of laser range finders usually involves installing a single test sample on a test platform inside an environmental test chamber and aligning the lens of the range finder with the light window of the test chamber. The emitted laser pulses pass through the light window, and the external energy meter receives and measures the light pulse energy. However, this testing method has obvious limitations: first, a single environmental test can only test a small number of range finders, resulting in low testing efficiency; second, a large amount of energy and manpower is consumed during environmental testing, leading to high production costs; finally, this inefficient testing method severely restricts the batch production progress of laser range finders, making it difficult to meet the production needs of cost reduction and efficiency improvement.

[0037] The utility model provides a kind of laser range finder testing device 100.

[0038] Please refer to Figures 1 to 4 In an embodiment of the utility model, the laser range finder testing device 100 has a box body 1, and the box body 1 is rotatably connected with a mounting seat 2 inside;

[0039] A detection part 3 is located outside the box body 1, and a light-transmitting window 11 is formed in the side wall of the box body 1, and the light-transmitting window 11 is correspondingly arranged with the detection part 3;

[0040] The mounting seat 2 is provided with a plurality of laser range finders 4, and the plurality of laser range finders 4 are distributed around the rotation axis of the mounting seat 2, so that different laser range finders 4 can be sequentially irradiated on the detection part 3 through the light-transmitting window 11.

[0041] It needs to be explained that in order to test the reliability of the laser range finder 4 under specific environmental conditions, some special environments need to be simulated inside the box 1, such as high and low temperature environments, and the increase and decrease of temperature need to consume a lot of energy. If a detection can only detect a small amount of the laser range finder 4, it will greatly increase the detection cost of a single laser range finder 4. Once the environment simulation can detect multiple laser range finders 4, it can effectively reduce the detection cost of a single laser range finder 4.

[0042] As shown in Figure 1 In order to ensure the environmental simulation effect, the inside of the box 1 is preferably closed during the simulation process. Therefore, the light-transmitting window 11 can ensure that the laser pulse emitted by the laser range finder 4 can pass through the box 1 and hit the detection part 3, and can also ensure the airtightness of the box 1, thereby maintaining the stable environmental conditions (such as temperature, humidity, air pressure, etc.) inside the box 1, providing a real test environment for the laser range finder 4, and reducing the heat exchange between the inside and outside of the box 1, thereby reducing energy consumption.

[0043] It needs to be explained that the detection part 3 includes a pulse laser energy meter, and the emission end of the laser range finder 4 to be detected is aligned with the light receiver of the pulse laser energy meter. The laser range finder 4 is detected by detecting the energy size.

[0044] The technical scheme of the utility model discloses a rotatable mounting seat 2 in the box 1, a plurality of laser range finders 4 are installed on the mounting seat 2, and the plurality of laser range finders 4 are distributed around the rotation axis of the mounting seat 2. By rotating the mounting seat 2, different laser range finders 4 can be aligned with the light-transmitting window 11 in turn and irradiated to the detection part 3 outside the box 1. This design enables single environmental test to test multiple laser range finders 4 at the same time, significantly improves the test efficiency, and since multiple laser range finders 4 can be tested in turn, the box 1 does not need to be frequently opened and closed, thereby reducing energy waste. At the same time, only one detection part 3 is needed during the test to complete the detection of multiple laser range finders 4, further reducing energy consumption. By improving the test capacity and efficiency of single test, the production cycle of the laser range finder 4 can be significantly shortened.

[0045] Optionally, the mounting seat 2 includes a plurality of mounting parts 21, which are distributed around the rotation axis of the mounting seat 2 and rotate around the rotation axis of the mounting seat 2 to install the laser range finder 4.

[0046] As shown in Figure 2As shown, it can be understood that the mounting seat 2 is provided with a plurality of mounting portions 21, which are distributed around the rotation axis of the mounting seat 2, and can fully utilize the space in the box body 1. By rotating the mounting seat 2, the laser range finder 4 on different mounting portions 21 can be aligned with the light transmission window 11 in turn, so that the rotation test of multiple devices can be realized. This design significantly improves the space utilization, so that more samples can be tested in a single environmental test.

[0047] In addition, the number of mounting portions 21 on the mounting seat 2 can be flexibly adjusted according to actual needs to adapt to different scales of test tasks. This flexibility makes the test device better meet the diversified production needs and improves the applicability of the test device.

[0048] In some embodiments, the mounting portion 21 is provided with a plurality of mounting holes to adapt to different specifications of the laser range finder 4. It can be understood that different specifications of the laser range finder 4 have different sizes, and the plurality of mounting holes can increase the applicability of the test device and reduce the equipment procurement and maintenance costs.

[0049] Optionally, the mounting seat 2 further comprises a plurality of rotating discs 22, the rotating discs 22 are rotationally connected to the box body 1, the mounting portion 21 is connected to the rotating disc 22 on opposite sides, and the rotating disc 22 drives the mounting portion 21 to rotate.

[0050] It should be noted that the rotating disc 22 drives the mounting portion 21 to rotate, so that the rotation of the mounting seat 2 is more stable and reliable. The supporting effect of the rotating disc 22 can effectively reduce the shaking of the mounting portion 21 during rotation, ensure that the laser range finder 4 maintains a stable alignment state during testing, and improve the testing precision.

[0051] As shown in the embodiment, Figure 2 In an embodiment, the number of rotating discs 22 is two, which are located on opposite sides of the mounting portion 21.

[0052] The mounting portion 21 is connected to the rotating disc 22 on opposite sides, so that the overall structure of the mounting seat 2 is more stable. The rotating disc 22 not only plays a role in rotating and driving, but also can share the weight of the mounting portion 21 and the laser range finder 4, thereby reducing the pressure on a single support point and prolonging the service life of the equipment.

[0053] Optionally, in some embodiments, the mounting portion 21 is detachably connected to the rotating disc 22. It can be understood that, due to the differences in size and installation requirements of the laser range finder 4 of different specifications, it is difficult to completely meet the installation requirements of all devices by only using multiple mounting holes. By detachably connecting the mounting portion 21 to the rotating disc 22, different specifications of the mounting portion 21 can be replaced according to actual requirements, thereby adapting to more types of the laser range finder 4, and the adaptability of the testing device is significantly improved.

[0054] In an embodiment, the mounting portion 21 is fixedly connected to the rotating disc 22 by bolts. It can be understood that, the bolt connection method is simple to operate, and only needs to tighten or loosen the bolts when the mounting portion 21 is detached and replaced, which is convenient for quick adjustment and replacement.

[0055] In another embodiment, the rotating disc 22 is provided with a plug-in interface, and the mounting portion 21 is plugged into the plug-in interface. The opening direction of the plug-in interface is parallel to the rotation axis direction of the rotating disc 22. After the mounting portion 21 is plugged into the plug-in interface, the movement of the mounting portion 21 is limited by a fastener. The fastener can be a screw, a bolt, or a movable blocking piece connected to the rotating disc 22. The blocking piece can block the plug-in interface to prevent the mounting portion 21 from moving. This embodiment does not make specific limitations. It can be understood that the plug-in connection method makes the mounting and dismounting of the mounting portion 21 more convenient. The operator only needs to plug the mounting portion 21 into the plug-in interface and fix it by the fastener, which significantly improves the operation efficiency. In addition, the design of the plug-in interface ensures that the mounting portion 21 can be accurately plugged into and fixed at the specified position, avoiding deviation during installation and improving testing accuracy.

[0056] In yet another embodiment, the rotating disc 22 is concave on both sides of the mounting portion 21 and is provided with a clamping gap. The opening direction of the clamping gap is consistent with the radial direction of the rotating disc 22. Two clamping gaps correspond to one clamping portion. The clamping portion is embedded in the clamping gap on both sides. It can be understood that the rotating disc 22 is provided with multiple clamping gaps, which are distributed at intervals around the rotation axis of the rotating disc 22. After the clamping portion is embedded in the clamping gap, the movement of the mounting portion 21 is limited by a fastener. The fastener can be a screw, a bolt, or a movable blocking piece connected to the rotating disc 22. The blocking piece can block the opening of the clamping gap to prevent the mounting portion 21 from moving radially along the rotating disc 22. This embodiment does not make specific limitations. It can be understood that the clamping gap enables the mounting portion 21 to be firmly embedded in the rotating disc 22, avoiding shaking or deviation of the mounting portion 21 during rotation, and ensuring the stability of the testing process.

[0057] It should be noted that the mounting portion 21 and the rotating disc 22 can also be connected by magnetic attraction, buckle connection, quick release pin connection and the like, and the present embodiment does not make specific limitation thereto.

[0058] Optionally, the mounting portion 21 comprises a mounting plate 211 and a clamping piece 212, and the number of the rotating discs 22 is two, and the two rotating discs 22 are respectively connected to the opposite sides of the mounting plate 211, and the clamping piece 212 is fixedly connected to the outer side surface of the mounting plate 211, so as to clamp the laser range finder 4.

[0059] It can be understood that the mounting plate 211 serves as the main structure of the mounting portion 21, and can provide a stable support platform for the laser range finder 4, and the two rotating discs 22 are respectively connected to the opposite sides of the mounting plate 211, so that the mounting portion 21 remains balanced during rotation, reducing the possibility of shaking and deviation, wherein the normal line of the mounting plane of the mounting plate 211 is parallel to the radial direction of the rotating disc 22.

[0060] In addition, the clamping piece 212 is fixedly connected to the outer side surface of the mounting plate 211, and can firmly clamp the laser range finder 4, preventing the equipment from loosening or falling off during testing, improving the stability of installation, ensuring the reliability of the testing process, and the clamping piece 212 can be adjusted according to different specifications of the laser range finder 4, so as to adapt to laser range finders 4 of different sizes and shapes. Such flexibility enables the testing device to be compatible with more specifications of the laser range finder 4, improving the applicability.

[0061] As shown in Figure 4 In an embodiment, the clamping piece 212 comprises a fixed block 2121 and a movable block 2122, the fixed block 2121 is fixedly connected to the mounting plate 211, and the movable block 2122 is movably connected to the mounting plate 211, and the movable block 2122 can move close to or away from the fixed block 2121 to clamp the laser range finder 4. Optionally, the movable block 2122 is threadedly connected to the mounting plate 211, and by rotating the movable block 2122, the movable block 2122 moves close to the fixed block 2121, thereby clamping the laser range finder 4. The movable design of the movable block 2122 enables the clamping piece 212 to adapt to laser range finders 4 of different sizes and shapes, meeting diversified testing needs.

[0062] In another embodiment, the clamping member 212 includes a fixed block 2121 and a movable block 2122. The movable block 2122 is connected to the mounting plate 211 by an elastic element. When the fixed block 2121 and the movable block 2122 clamp the laser rangefinder 4, the elastic element is in a compressed state. The elastic element pushes the movable block 2122 to move towards the fixed block 2121 to clamp the laser rangefinder 4.

[0063] Optionally, the mounting base 2 further includes a rotating shaft 23, the turntable 22 is connected to the rotating shaft 23, and the turntable 22 rotates around the axis of the rotating shaft 23, and the rotating shaft 23 is rotatably connected relative to the housing 1.

[0064] like Figure 2 As shown, it should be noted that the rotating shaft 23, as the rotation center, can provide stable support for the turntable 22, ensuring that the turntable 22 remains stable during rotation, reducing swaying and offset. Furthermore, the multiple turntables 22 are relatively fixed to the rotating shaft 23, which can make the rotation angle of the multiple turntables 22 the same.

[0065] Furthermore, by controlling the rotation angle of the rotating shaft 23, the position of the mounting part 21 can be precisely adjusted to ensure that each laser rangefinder 4 can be accurately aligned with the light-transmitting window 11.

[0066] Optionally, one end of the rotating shaft 23 is connected to a driving member 231, which is used to drive the rotating shaft 23 to rotate.

[0067] like Figure 3 As shown, it can be understood that the drive component 231 can automatically drive the rotating shaft 23 to rotate without manual intervention, thus automating the testing process. The automated rotation function enables multiple laser rangefinders 4 to take turns testing efficiently, significantly improving testing efficiency and supporting the need for batch testing.

[0068] The drive component 231 can precisely control the rotation angle of the rotating shaft 23 through the control system, ensuring that each laser rangefinder 4 can accurately align with the light-transmitting window 11, thereby improving the testing accuracy. Optionally, the drive component 231 includes a motor, the output shaft of which is connected to the rotating shaft 23 to drive the rotating shaft 23 to rotate.

[0069] In some embodiments, the laser rangefinder testing device 100 further includes a control center 6, which is electrically connected to the drive component 231. The control center 6 controls the rotation angle of the drive component 231 to realize the sequential detection of the laser rangefinder 4 at different positions.

[0070] Optionally, the rotating shaft 23 is connected with a rotating transmission member 232 at one end, the rotating transmission member 232 comprises an input end and a plurality of output ends, and the output ends are rotationally connected with the input end;

[0071] The number of the output ends of the rotating transmission member 232 corresponds to the number of the laser range finders 4, the output ends of the rotating transmission member 232 are connected with the laser range finders 4 and rotate with the laser range finders 4 to supply power to the laser range finders 4.

[0072] As shown in Figure 2 It is to be noted that the rotating transmission member 232 can transmit electric energy from the input end to the plurality of output ends while allowing the output ends to rotate relative to the input end, thereby providing stable power supply for the rotating laser range finders 4 and avoiding cable winding. The rotating transmission member 232 avoids the problem of cable winding in the conventional power supply mode and ensures smooth testing process.

[0073] The number of the output ends of the rotating transmission member 232 can be expanded according to the number of the laser range finders 4 to meet the testing requirements of different scales.

[0074] In some embodiments, the rotating transmission member 232 comprises a conductive slip ring, the output ends of the conductive slip ring can rotate relative to the input end of the conductive slip ring, and the stable power supply is ensured.

[0075] As shown in Figure 1 In some embodiments, the rotating transmission member 232 is electrically connected with the control center 6, the control center 6 controls the on-off of the plurality of output ends of the rotating transmission member 232, when the driving member 231 drives the laser range finder 4 to be detected to rotate to a specified position, the control center 6 controls the output end corresponding to the laser range finder 4 to be detected to be connected, the laser range finder 4 emits a laser pulse to perform detection.

[0076] And, when the driving member 231 drives the rotating shaft 23 to rotate, the control center 6 receives the electrical signal of the driving member 231, the control center 6 controls the output end of the rotating transmission member 232 to be disconnected, so as to prevent the laser range finder 4 from being misstarted in the rotating process. It should be noted that the laser pulse power of the laser range finder 4 is large, when the laser pulse emitted by the laser range finder 4 does not pass through the light-transmitting window 11, the laser pulse may be reflected on the inner wall of the box 1, which may cause damage to the device. Therefore, through the control center 6, the laser range finder 4 can be started only after reaching the specified position, so as to ensure that the laser pulse is emitted only through the light-transmitting window 11, avoid the potential damage of the laser pulse to the inner wall of the box 1 or other components, prevent misstart, and ensure the safe operation of the equipment.

[0077] Secondly, after the detection of the laser range finder 4 is completed, the control center 6 controls the output end of the rotating transmission member 232 to be disconnected, and then drives the rotating shaft 23 to rotate through the driving member 231, so as to rotate the next laser range finder 4 to be detected to the specified position. It should be noted that the control mode of disconnecting power supply first and then rotating can avoid the potential damage of the laser pulse to the inner wall of the box 1 or other components, prevent misstart, and ensure the safe operation of the equipment.

[0078] As shown in Figure 1 In some embodiments, the control center 6 includes an upper computer 61 and a lower computer 62, the lower computer 62 is electrically connected with the driving member 231 and the rotating transmission member 232, and the upper computer 61 is electrically connected with the lower computer 62 to obtain signals and process them.

[0079] Secondly, the laser range finder 4 is started only after reaching the specified position, which can effectively save the consumption of energy.

[0080] Optionally, the rotating shaft 23 is hollow, and a plurality of through holes are distributed at intervals around the axis on the side wall of the rotating shaft 23.

[0081] The output end of the rotating transmission member 232 is connected with an output line 233, the output line 233 is inserted into the rotating shaft 23 and passes out from the through hole to connect the laser range finder 4.

[0082] It should be noted that the rotating shaft 23 is hollow, and a plurality of through holes are distributed at intervals around the axis on the side wall of the rotating shaft 23, so that the output line 233 can pass through the inside of the rotating shaft 23 and pass out from the through hole, and be directly connected to the laser range finder 4. Avoid the winding problem of the output line 233 in the rotating process in the traditional wiring mode, ensure the stable operation of the test device, at the same time, simplify the wiring structure inside the equipment, reduce the complexity of installation and maintenance.

[0083] Optionally, the laser range finder testing device 100 further comprises a base 5, which is arranged in the box 1, and the rotating shaft 23 is rotatably connected to the base 5.

[0084] It should be noted that the base 5 serves as the mounting base of the rotating shaft 23, which can provide stable support for the rotating shaft 23, ensure that the rotating shaft 23 remains stable during rotation, reduces shaking and deviation, and makes the overall structure of the testing device more stable and can withstand greater load. It can be understood that the base 5 is fixed relative to the inside of the box 1, and the rotating shaft 23 rotates relative to the base 5, i.e. relative to the box 1;

[0085] In some embodiments, the base 5 is placed inside the box 1, and after the test is completed, the base 5 can be removed for easy replacement and installation of the laser pulse and for easy maintenance;

[0086] Further, a plurality of laser range finders 4 can be pre-installed on different bases 5, and only the base 5 needs to be replaced during testing, which significantly improves the testing efficiency.

[0087] In other embodiments, the rotating shaft 23 is directly rotatably connected to the side wall of the box 1.

[0088] Optionally, the mounting seat 2 is provided with a plurality of conductive pieces, one end of which is connected to the laser range finder 4, and the other end is located on the outer side wall of the rotating disc 22. The conductive pieces are distributed at intervals around the rotation axis of the rotating disc 22.

[0089] The base 5 is provided with a brush, one end of which abuts against the outer side wall of the rotating disc 22. The brush is in turn connected to the conductive pieces to supply power to the laser range finder 4 when the rotating disc 22 rotates.

[0090] It should be noted that the conductive pieces are distributed at intervals around the rotation axis of the rotating disc 22, and the brush abuts against the outer side wall of the rotating disc 22. By rotating the rotating disc 22, the brush is in turn connected to different conductive pieces, thereby providing stable power supply for the laser range finder 4.

[0091] It can be understood that when a certain laser range finder 4 is aligned with the light-transmitting window 11, the brush is connected to the corresponding conductive piece of the laser range finder 4, so that the laser range finder 4 is powered on, and the laser range finder 4 emits a laser pulse through the light-transmitting window 11. The brush is only connected to the corresponding conductive piece when the laser range finder 4 is aligned with the light-transmitting window 11, which ensures that the laser range finder 4 only emits a laser pulse at a designated position, avoiding damage to equipment or safety hazards caused by emission of a laser pulse at a non-designated position.

[0092] The above merely describes exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, made by using the present application specification and drawings, are included in the patent protection scope of the present application.
