Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wide-angle lens detection, in particular to a vehicle-mounted large wide-angle lens ring test bench. BACKGROUND

[0002] With the popularization of new energy vehicles, the driving assistance system has become a standard configuration of the automobile, and the vehicle-mounted wide-angle lens is the "eyes" of the driving assistance system, so the actual performance of the vehicle-mounted wide-angle lens plays a crucial role in the driving assistance system.

[0003] The vehicle-mounted wide-angle lens is an important component in the automobile driving assistance system, which can image and monitor the environment around the vehicle body without dead angle, capture the details of the road environment around the vehicle through high light transmission, and thus improve the driving experience of the driver and the safety of the vehicle driving.

[0004] In order to detect the performance of the vehicle-mounted wide-angle lens in actual road conditions, its light transmission capability, imaging clarity and resolution capability need to be detected.

[0005] At present, the vehicle-mounted wide-angle lens is mainly detected by a collimator system and a relay lens, but this detection method has certain limitations. Since the new energy vehicles are used in different road conditions, the jolt degree of the vehicle body driving on different road surfaces is different. Once the jolt amplitude of the vehicle body is too large, the imaging clarity of the lens to the surrounding environment and the resolution capability of the surrounding objects will be disturbed.

[0006] In view of this, a vehicle-mounted large wide-angle lens ring test bench is designed to solve the above problems. SUMMARY

The inner end of the first bolt is provided with a cylindrical anti-skid plug.

[0013] The application can be further configured in a preferred example that the light-shielding pad is externally provided with a black light-shielding layer.

The application sets a simulation jolting mechanism in an existing closed light-shielding laboratory, and sets an optical distance angle adjusting mechanism for assembling a wide-angle lens on the simulation jolting mechanism. When the wide-angle lens is fixed, the multiple parallel light tubes that are uniformly distributed and suspended can project the detection light towards the wide-angle lens. When the simulation jolting mechanism applies a vibration force to the parallel light tubes, the multiple parallel light tubes that are regularly shaken can simulate the jolting state of the wide-angle lens, thereby realizing real-time detection of the surrounding road surface environment.

[0019] 2. This invention allows multiple sets of angle control components to selectively adjust the height along multiple sliding plates, enabling these components to pull multiple cables. The evenly distributed multiple arc tracks then create a certain height difference, allowing the parallel light tube with the adjusted tilt angle to simulate different shadow areas in the external environment. This, in turn, simulates the capture of objects in shadow areas around the vehicle by a wide-angle lens under shaking conditions.

[0020] 3. This invention stretches the light tube angle adjustment mechanism horizontally, causing the arc track to expand outward under pressure. This allows for further adjustment of the depth between the light irradiated by the collimator and the wide-angle lens. With selective control of the light depth, the wide-angle lens can then perform gradual depth imaging measurements in a shaded environment, thereby improving the accuracy of the sharpness detection of the wide-angle lens image after imaging by multiple collimators with different degrees of expansion.

[0029] Embodiment 2: In combination Figures 3 to 4 As shown in the figure, on the basis of embodiment 1, the simulation bumping mechanism 100 includes a base 110 mounted outside the base 210 and a first gasket 190, a motor 120 mounted inside the base 110, a wheel disc 130 mounted on the transmission shaft inside the motor 120, a traction member 140 movably mounted on the wheel disc 130, an inclined frame 150 movably connected to the other end of the traction member 140, a supporting plate 160 movably mounted on the top end of the inclined frame 150, a plurality of supporting frames 170 mounted on the top of the supporting plate 160, and a connecting frame 180 movably mounted on the top of the supporting frame 170.

[0030] Preferably, the base 110 is fixedly installed in a light-shielded laboratory by bolts, and the light-shielded gasket 300 cooperates with the light-shielded laboratory to provide a single light source for the wide-angle lens detection. When the motor 120 is started, the transmission shaft inside the motor 120 drives the wheel disc 130 to rotate, which drives the traction member 140 to reciprocatingly stretch, and finally the inclined frame 150 connected to the other end of the traction member 140 drives the supporting plate 160 and the plurality of supporting frames 170 to regularly lift; The connecting frame 180 movably connected to the top end of the supporting frame 170 drives the multiple groups of height-adjusted light distance heightening assemblies 240 to reciprocatingly lift, and at this time the multiple groups of height-adjusted light distance heightening assemblies 240 can cooperate with the multiple cables 250 to exert the resonance kinetic energy on the multiple height-adjusted arc tracks 490.

[0032] Preferably, the inner end of the gasket 234 is attached to the outer wall of the sleeve 221. When the limiting post 231 loses external force, the first spring 233 will apply an outward pushing force to the limiting post 231. At this time, the pressed anti-slip pad 232 can fix the slide plate 260 on the inner wall of the sleeve 221. The fixed slide plate 260 can provide a stable lifting platform for the optical distance adjustment component 240, and at the same time, it can provide a rotation platform for the local fine adjustment of the optical distance adjustment component 240. Thus, it can work with the cable 250 to further control the height of the resonant platform 480 and the arc rail 490.

[0033] Example 4: Combination Figures 8 to 10 As shown, in the above embodiment, the cable pitch adjustment mechanism 500 includes two suspensions 510 fixedly installed on the resonance platform 480, two stabilizing brackets 520 movably installed at the bottom of the two suspensions 510, a shaft 540 movably installed between the two stabilizing brackets 520, a guide wheel 550 movably installed outside the shaft 540, and an anti-disengagement buckle 560 fixedly installed outside the shaft 540. The side of the guide wheel 550 is provided with an annular groove for the guide cable 250; The stabilizing bracket 520 consists of a support leg, a T-shaped limiting rod, and a plug. A third spring 530 is provided on the outside of the T-shaped limiting rod, and the plug is used to provide limiting protection for the suspension 510.

[0034] Preferably, the two suspensions 510 are fixed to the load-bearing member 450 by welding, and the two T-shaped limiting rods pass through the transverse holes at the bottom of the two suspensions 510 respectively, while one end of the third spring 530 is pressed against the bottom end of the suspension 510, and the other end of the third spring 530 is pressed against the top of the support leg. When the cable 250 is pulled, the guide wheel 550 provides an anti-slip platform and a guide platform for the reciprocating extension of the cable 250, while the anti-disengagement buckle 560 works with the guide wheel 550 to provide limit protection for the cable 250 after reciprocating extension.

[0035] Working principle and usage process of this invention: The plurality of second bolts 274 are adjusted in advance by using a wrench to reverse, at which time the threaded section of the second bolt 274 will extend outward along the sleeve 273, and the inner end of the second bolt 274 will pull the compression pad 275 close to the inner wall of the assembly table 271, at which time the gap between the plurality of compression pads 275 will be expanded, and then the wide-angle lens to be tested is placed in the middle of the inner cavity of the assembly table 271, and after the wide-angle lens is placed, the plurality of second bolts 274 are adjusted again by using a wrench to rotate in the forward direction until the plurality of compression pads 275 are compressed to fix the wide-angle lens; When the wide-angle lens is fixed and the lens is upward, the plurality of collimating tubes 600 can be selectively adjusted to move upward along the arc track 490 until the lens at the bottom of the collimating tube 600 forms a certain angle with the upward lens of the wide-angle lens. The height and inclination angle of the plurality of collimating tubes 600 can be gradually implemented during each test. After the plurality of collimating tubes 600 are adjusted, the first bolt 244 is reversed until the sliding table 241 and the sliding plate 260 are in a relaxed state, and then the motor 120 is started. At this time, the forward rotation of the transmission shaft in the motor 120 drives the wheel disc 130 to rotate at a constant speed, and the off-center stud on the outer side of the wheel disc 130 drives the traction member 140 and the inclined frame 150 to reciprocatingly extend along the center line of the transmission shaft, and the support plate 160 and the plurality of support frames 170 arranged at the other end of the inclined frame 150 are compressed to reciprocatingly rise and fall, and finally the plurality of support frames 170 pull the plurality of connecting frames 180, and the plurality of groups of optical distance height adjustment assemblies 240 arranged on the plurality of connecting frames 180 and uniformly distributed reciprocatingly slide along the plurality of sliding plates 260. With the reciprocating sliding of the plurality of groups of optical distance height adjustment assemblies 240, the inhaul cable 250 is pressed by the optical distance height adjustment assembly 240 to drive the resonance table 480 and the arc track 490 to vibrate, at which time the collimating tube 600 fixed at a certain inclination angle on the arc track 490 can keep regular vibration, and the shaking light can irradiate the wide-angle lens, at which time the stationary wide-angle lens can image and detect the actively vibrating collimating tube 600, and this process can simulate the capture of the clarity of the surrounding light environment of the wide-angle lens on the real road surface after the wide-angle lens bounces on the real road surface. When the level of external environmental light irradiation needs to be simulated, the height of the plurality of groups of angular position control assemblies 230 can be selectively adjusted until the plurality of arc tracks 490 uniformly distributed form a certain height difference, and the plurality of collimating tubes 600 arranged on the plurality of arc tracks 490 can change angles, and the plurality of collimating tubes 600 after changing angles will irradiate the wide-angle lens at a certain height difference.
