Description

Technical Field

[0001] This utility model relates to the field of laser target simulator technology, and in particular to a portable laser target simulator. Background Technology

[0002] A target simulator is a testing instrument that generates specific signals to simulate the characteristics of real targets. It is widely used in the research and verification of radar systems, autonomous driving technology, and wireless communications. Its core technologies include multi-mode frequency source design, dynamic scene simulation, and high-precision signal echo modeling, enabling accurate simulation of target behavior in complex environments (such as traffic scenarios and weather interference). In the field of autonomous driving, 4D radar target simulators can reduce testing costs and improve the reliability of millimeter-wave radar under extreme conditions. Instrument manufacturers are continuously promoting the application of target simulators in performance testing and system calibration by integrating multi-channel and high-bandwidth technologies.

[0003] For example, the portable laser target simulator disclosed in Chinese Patent CN 219284115 U belongs to the field of optical imaging equipment technology. This utility model includes a housing, a three-piece optical lens, a pitch and yaw adjustment device, a laser source, a collimating lens, and an aperture stop. The three-piece optical lens is mounted on the right side wall of the housing. The laser source is installed inside the housing via the pitch and yaw adjustment device. A collimating lens and an aperture stop are also sequentially mounted on the pitch and yaw adjustment device in front of the laser source. The laser beam emitted by the laser source passes sequentially through the collimating lens, the aperture stop, and the three-piece optical lens. The purpose of this development is to solve the problems of traditional laser target simulators, such as cumbersome operation, poor portability, limited application range, and difficulty in adapting to special testing scenarios such as production and outdoor environments with limited installation conditions. Compared with traditional simulators, this utility model has a higher degree of integration, adopting an integrated design that combines the laser source and control box into one unit. It is small in size, lightweight, easy to operate, and easy to move, making it more practical.

[0004] While the aforementioned laser target simulator integrates multiple components into a single housing for portability, the lack of a handle on the housing surface limits its portability, especially considering its weight. Furthermore, since the lens requires the laser beam to originate externally and couple into the tested photoelectric system, and the tested system is independently configured with the simulator, the simulator's height must be adjusted to align with the tested photoelectric system for better simulation testing. Therefore, this application aims to further combine height adjustability with portability, and proposes a portable laser target simulator. Utility Model Content

[0005] Based on this, it is necessary to provide a portable laser target simulator to address the aforementioned technical problems. Through the design of the handle support unit, the simulator can be easily carried and applied through the U-shaped support frame. At the same time, when in use, the U-shaped support frame can be flipped to the bottom of the body, which can form a highly adaptable adjustment to the laser beam emitted by the lens and the photoelectric system under test, further facilitating actual simulation testing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A portable laser target simulator includes a body with clearance grooves on both sides. Guide rails are fixed on both sides inside the clearance grooves. A sliding seat is slidably assembled between the two guide rails in a single clearance groove. A positioning post fixed to the bottom wall of the clearance groove is slidably inserted in the middle of the sliding seat. A positioning bolt for fastening the positioning post is threaded through the surface of the sliding seat.

[0008] Both sides of the sliding seat are provided with handle support units, each handle support unit including a U-shaped support frame, which is assembled with the sliding seat by a locking member.

[0009] Furthermore, the locking member includes a movable cavity formed inside the sliding seat, a sliding block is slidably disposed in the movable cavity, one end of the sliding block extends through the outside of the sliding seat to form a support portion, and the U-shaped support frame is movably sleeved on the surface of the support portion.

[0010] Furthermore, a spring is also connected to one side wall of the movable cavity and fixed to the sliding block, and the support part can extend out of the sliding seat under the action of the spring.

[0011] Furthermore, the surface of the U-shaped support frame is provided with a movable groove, and the U-shaped support frame is movably fitted onto the surface of the support part through the movable groove.

[0012] Furthermore, the support portion extends through one side of the movable groove to form a limiting portion.

[0013] Furthermore, a limiting rod is fixed to the inner side of the limiting part, and a limiting groove adapted to the limiting rod is provided on the surface of the U-shaped support frame.

[0014] Furthermore, an optical lens group is installed on one side of the body, and a support frame is also assembled inside the body. An adjustment frame is provided on the inner side of the support frame. A first motor fixed to the support frame is connected to one side of the adjustment frame, and a second motor is connected to the top of the adjustment frame. The output end of the second motor passes through the adjustment frame and is fixed with an orientation plate.

[0015] Furthermore, a laser source is fixed on one side of the azimuth plate, and a collimating lens corresponding to the laser source is fixed on the other side of the azimuth plate. The collimating lens has an aperture stop inside, so that the laser beam emitted by the laser source passes through the collimating lens, the aperture stop and the optical lens group in sequence, and finally couples into the photoelectric system under test at the exit pupil position.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The portable laser target simulator provided by this utility model, through the design of the handle support unit, can not only facilitate the further carrying and application of the simulator through the U-shaped support frame, but also, when in use, the U-shaped support frame can be flipped to the bottom of the body. This allows for highly adaptive adjustment of the laser beam emitted by the lens and the photoelectric system under test, further facilitating actual simulation testing. Attached Figure Description

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] Example 1

[0032] Please refer to Figures 1-5 As shown, a portable laser target simulator includes a body 1. Both sides of the body 1 have clearance grooves 11. Guide rails 12 are fixed to both sides inside each clearance groove 11. A sliding seat 13 is slidably mounted between two guide rails 12 within a single clearance groove 11. A positioning post 14, fixed to the bottom wall of the clearance groove 11, slides through the middle of the sliding seat 13. A positioning bolt 15 for fastening the positioning post 14 is threaded through the surface of the sliding seat 13. The positioning post 14 guides the sliding seat 13 in the height direction, making it more stable during vertical sliding. Rotating the positioning bolt 15 so that one end abuts against the surface of the positioning post 14 allows adjustment of the height of the sliding seat 13, thereby adjusting the support height of the handle support unit 2.

[0033] Both sides of the sliding seat 13 are provided with handle support units 2. The handle support unit 2 includes a U-shaped support frame 21. The U-shaped support frame 21 is assembled with the sliding seat 13 through a locking member 22. Through the design of the U-shaped support frame 21, the simulator can be carried. The hand can directly pick up the U-shaped support frame 21 to achieve the effect of lifting, which further improves the portability of the simulator.

[0034] Example 2

[0035] The portable laser target simulator provided in Example 1 has been further optimized, specifically, as follows: Figure 3As shown, the locking member 22 includes a movable cavity 220 opened inside the sliding seat 13, and a sliding block 221 is slidably disposed in the movable cavity 220. The sliding block 221 can slide in the movable cavity 220. One end of the sliding block 221 passes through the outside of the sliding seat 13 to form a support portion 222. The U-shaped support frame 21 is movably sleeved on the surface of the support portion 222.

[0036] A spring 223, which is fixed to the sliding block 221, is also connected to one side wall of the movable cavity 220. The support part 222 can extend out of the sliding seat 13 under the action of the spring 223.

[0037] The surface of the U-shaped support frame 21 is provided with a movable groove 210, and the U-shaped support frame 21 is movably fitted onto the surface of the support part 222 through the movable groove 210;

[0038] The support part 222 passes through one side of the movable groove 210 to form a limiting part 224. Through the design of the limiting part 224, the U-shaped support frame 21 can be freely rotated on the surface of the support part 222, while preventing it from falling off the support part 222.

[0039] Furthermore, a limiting rod 225 is fixed to the inner side of the limiting part 224, and a limiting groove 211 adapted to the limiting rod 225 is opened on the surface of the U-shaped support frame 21. There are multiple limiting grooves 211, which are evenly distributed along the central axis of the limiting part 224. Under the action of the spring 223, the limiting rod 225 is inserted into the corresponding limiting groove 211 in the natural state. At this time, the angle of the U-shaped support frame 21 is fixed, and the U-shaped support frame 21 maintains a stable angle in this state.

[0040] When it is necessary to adjust the angle of the U-shaped support frame 21, the limiting part 224 is pulled outward to overcome the force of the spring 223, so that the limiting rod 225 is disengaged from the corresponding limiting groove 211. At this time, the U-shaped support frame 21 is not subject to the limiting effect and can rotate freely on the surface of the supporting part 222, thereby adjusting the angle of the U-shaped support frame 21.

[0041] By adjusting the angle of the U-shaped support frame 21, such as... Figure 1 As shown, when carrying the simulator, the hands can better grip the two U-shaped support frames 21, making it easier to carry and use. Furthermore, when using the simulator, as... Figure 2 As shown, by flipping the U-shaped support frame 21 to the bottom of the body 1, an overall support effect is formed for the simulator, thereby allowing the overall application height of the simulator to be adjusted;

[0042] At the same time, the height of the sliding seat 13 can be adjusted relative to the surface of the positioning column 14 by adjusting the positioning bolt 15, thereby further increasing the range of height adjustment of the simulator and achieving a better matching effect with the coverage of the photoelectric system under test.

[0043] Example 3

[0044] The portable laser target simulator provided in Embodiment 1 or 2 is further optimized, such as... Figure 4 and Figure 5 As shown, an optical lens group 3 is installed on one side of the body 1. In this embodiment, the optical lens group 3 includes a first optical lens, a second optical lens, and a third optical lens in sequence. A support frame 4 is also installed inside the body 1. An adjustment frame 41 is provided on the inner side of the support frame 4. A first motor 42 fixed to the support frame 4 is connected to one side of the adjustment frame 41. A second motor 43 is connected to the top of the adjustment frame 41. The output end of the second motor 43 passes through the adjustment frame 41 and a directional plate 44 is fixed inside it.

[0045] A laser source 45 is fixed on one side of the orientation plate 44, and a collimating lens 46 corresponding to the laser source 45 is fixed on one side of the orientation plate 44. The collimating lens 46 has an aperture stop 47 inside, so that the laser beam emitted by the laser source 45 passes through the collimating lens 46, the aperture stop 47 and the optical lens group 3 in sequence, and finally couples into the photoelectric system under test at the exit pupil position.

[0046] The laser source 45 emits a laser beam, which is collimated into parallel light by the collimating lens 46, and then passes through the aperture stop 47, turning the laser beam emitted by the laser source 45 into a thin laser beam with a diameter of Φ0.3mm. Under the adjustment of the support frame 4, the laser source 45 rotates independently in the pitch and azimuth directions with the aperture center of the aperture stop 47 as the rotation center. The rotation angle gradually rotates from 0° to ±15°. After passing through the optical lens group 3, it finally couples into the photoelectric system under test at the exit pupil position to realize the simulation test of the laser target.

[0047] When adjusting the pitch motion, the first motor 42 works, driving the adjustment frame 41 to rotate the pitch angle on the support frame 4. When adjusting the azimuth motion, the second motor 43 works, driving the adjustment frame 41 to rotate the azimuth angle on the support frame 4.

[0048] The independent rotation of the laser source 45 in both pitch and azimuth directions enables the field of view of this embodiment to reach ±15°. The rotation process does not affect the exit pupil position, that is, the exit pupil position remains unchanged when the laser source 45 rotates in both pitch and azimuth directions.

[0049] The internal structure of the body 1 in this embodiment is common knowledge to those skilled in the art, so it is not further elaborated in this embodiment. For example, the interior of the body 1 may also include a touch screen all-in-one machine, an industrial control board, a rechargeable lithium battery, electrical connectors, etc. It can be referred to the portable laser target simulator disclosed in Chinese Patent CN 219284115 U. The simulation distance and structural composition of the laser target simulator in this embodiment are consistent with it.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
