Therefore, before selecting pilots, their vision needs to be strictly tested. The actual working environment of pilots is relatively complex. The test environment of the existing pilot vision test device is very different from the actual working environment of the pilots. The test results cannot fully reflect the visual ability of the pilots.

[0003] For example, the patent publication number CN202021522936.8 discloses a multi-scenario pilot vision test device, which simulates a flight environment similar to the actual working environment of the pilot through a variety of different scenarios (sunny, cloudy, rain, fog, snow, night, vibration), making the pilot's vision test results more accurate.

Secondly, there are various obstacles during the flight of the aircraft, and the pilot needs to avoid these obstacles.

[0040] The following is combined with Figure 1-5 The utility model is described in further detail.

[0041] Embodiment 1, refer to Figure 1-2 In order to solve the problem that the existing obstacle simulation test cannot be performed, the utility model discloses a multi-scenario pilot vision test device.

[0042] The device assembly 100 includes a device body 101, a top plate 102 is connected to the top of the device body 101, and a test vehicle 103 is arranged inside the device body 101;

[0043] The auxiliary component 200 also includes a fixed block 201, which is located below the top plate 102. A cylinder 202 is connected below the fixed block 201, and a piston rod 203 is driven to rise and fall by the cylinder 202, so as to subsequently raise and lower the first display screen 205. A piston rod 203 is connected below the cylinder 202, and an auxiliary block 204 is connected below the piston rod 203. The inner side of the auxiliary block 204 is connected to the first display screen 205, and obstacles are simulated by the first display screen 205 to test the pilot's ability to respond to obstacles.

[0044] The device body 101 and the top plate 102 are installed in an integrated manner. The second display screens 301 are symmetrically distributed on both sides of the device body 101, and the first display screen 205 is symmetrically distributed below the top plate 102. The first display screen 205 cooperates with the second display screen 301 to simulate weather and obstacles under different conditions to ensure good test results.

[0045] The fixing block 201 and the cylinder 202 are installed in an integrated manner. The fixing block 201 is symmetrically distributed below the top plate 102. The connection between the cylinder 202 and the piston rod 203 is a piston connection. The cylinder 202 is fixed by the fixing block 201, thereby facilitating the subsequent use of the piston rod 203 and ensuring the testing work.

[0046] The piston rod 203 and the auxiliary block 204 are connected by hot-melt connection. The center point of the auxiliary block 204 coincides with the center point of the first display screen 205. The auxiliary block 204 and the first display screen 205 are installed in an integrated manner. The first display screen 205 is limited and fixed by the auxiliary block 204, so that the first display screen 205 can be raised and lowered to complete the test work at different heights and improve the test results.

[0047] The specific working principle is: first, during the test, the second display screen 301 is turned on to simulate scenarios under different weather conditions, and at the same time, the first display screen 205 is turned on so that the first display screen 205 simulates various obstacles. At this time, the pilot who needs to be tested enters the interior of the test vehicle 103 and performs tests according to the obstacles and weather conditions under different conditions. When it is necessary to test living obstacles, the switch of the cylinder 202 is turned on so that the cylinder 202 drives the piston rod 203 to operate, and the rear piston rod 203 drives the auxiliary block 204 to rise and fall, so that the first display screen 205 rises and falls, so that when the first display screen 205 rises and falls, the obstacles it simulates will also rise and fall, thereby assisting in the movement test of living obstacles.

[0048] Example 2, refer to Figure 1-3 In this embodiment, in order to solve the problem that the existing test device cannot perform the test work under the condition of aircraft tilt, based on the same concept as the above-mentioned embodiment 1, the multi-scenario pilot vision test device also includes:

[0049] The adjustment component 300 also includes a second display screen 301. The second display screen 301 is located on both sides of the device body 101. A driving rod 302 is connected to the center of the second display screen 301. A driving motor 303 is connected to the other side of the driving rod 302. The driving motor 303 drives the driving rod 302 to rotate, so that the driving rod 302 drives the second display screen 301 to rotate, simulating the tilt of the aircraft. An extension rod 304 is connected to the inner side of the second display screen 301. A limiting block 305 is connected to the inner side of the extension rod 304. The limiting block 305 cooperates with the extension rod 304 to ensure the stability of the second display screen 301.

[0050] The second display screen 301 is a combined display screen. The second display screen 301 and the driving rod 302 rotate in an integrated manner. The driving rod 302 and the driving motor 303 are connected by a key connection. The second display screen 301 is driven to rotate by the driving rod 302, thereby simulating an aircraft at different angles to ensure accurate test results.

[0051] Extension rods 304 are symmetrically distributed on both sides of the second display screen 301. The extension rods 304 are connected to the limit blocks 305 by sliding connection. The limit blocks 305 are integrated with the device body 101. The limit blocks 305 cooperate with the extension rods 304 to assist in limiting the second display screen 301 to prevent it from shaking during rotation.

[0052] The second motor 401 is connected to the threaded rod 402 by a key connection, and the threaded rod 402 is connected to the threaded block 403 by a threaded connection. The threaded rod 402 forms a sliding structure with the top plate 102 through the support block 406. The threaded rod 402 is driven to rotate by the second motor 401, thereby adjusting the position of the threaded block 403 to facilitate subsequent work. At the same time, the support block 406 is used to support the threaded block 403 to prevent the threaded rod 402 from deforming.

[0053] The specific working principle is: as mentioned above, when it is necessary to simulate the scenario of the aircraft tilting, turn on the switch of the driving motor 303, so that the driving motor 303 drives the driving rod 302 to rotate, and the driving rod 302 drives the second display screen 301 to rotate, so that the second display screen 301 rotates, and when a certain angle is reached, the switch of the driving motor 303 is stopped, and at the same time, the second display screen 301 slides inside the limit block 305 through the extension rod 304, to ensure that the second display screen 301 will not shake during the rotation process and cause accidental falling off.

[0054] Example 3, refer to Figure 4-5 In this embodiment, in order to solve the problem that the existing first display screen 205 can only be raised and lowered but not moved, based on the same concept as the above-mentioned embodiment 1, the multi-scenario pilot vision test device also includes:

[0055] The moving assembly 400 also includes a second motor 401, which is located inside the top plate 102. A threaded rod 402 is connected to the other side of the second motor 401, and the threaded block 403 is driven to move by the threaded rod 402, thereby driving the first display screen 205 to move. The outer side of the threaded rod 402 is connected to a threaded block 403, and the bottom of the threaded block 403 is connected to a connecting block 405. The bottom of the connecting block 405 is connected to an adjusting block 404, which is connected to the cylinder 202 through the adjusting block 404 to assist in fixing. Support blocks 406 are also connected to both sides below the threaded block 403, and the threaded block 403 is supported by the support blocks 406 to prevent it from damaging the threaded rod 402.

[0056] The second motor 401 is connected to the threaded rod 402 by a key connection, and the threaded rod 402 is connected to the threaded block 403 by a threaded connection. The threaded rod 402 forms a sliding structure with the top plate 102 through the support block 406. The threaded rod 402 is driven to rotate by the second motor 401, thereby adjusting the position of the threaded block 403 to facilitate subsequent work. At the same time, the support block 406 is used to support the threaded block 403 to prevent the threaded rod 402 from deforming.

[0057] The threaded block 403 and the connecting block 405 are connected by hot-melt connection. The connecting block 405 and the adjusting block 404 and the cylinder 202 are installed in an integrated manner. The adjusting block 404 and the top plate 102 are connected by sliding connection. The threaded block 403 cooperates with the connecting block 405 to drive the adjusting block 404 and the first display screen 205 thereunder to move, so that obstacles can move freely.

[0058] The specific working principle is: as mentioned above, when the obstacle needs to be moved, turn on the switch of the second motor 401, so that the second motor 401 drives the threaded rod 402 to rotate, so that the threaded rod 402 and the threaded block 403 have a threaded motion, so that the threaded block 403 moves. When the threaded block 403 moves, it slides with the top plate 102 through the supporting block 406 below, so as to prevent the first display screen 205 from being too heavy and causing the threaded rod 402 to bend. At the same time, the threaded block 403 drives the adjustment block 404 to move through the connecting block 405, so that the adjustment block 404 drives the first display screen 205 below to move, simulating the movement of an obstacle.

[0059] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
