[0023] The present invention will be further described below with reference to the accompanying drawings. All directional terms used in this description are based on the driver's position. "Front" refers to the area in front of the driver, i.e., the front engine compartment; "rear" refers to the area behind the driver, including the rear seats, luggage compartment, etc. Left and right directions are based on the driver's left and right sides. It should be noted that terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate the position or orientation based on the positions or orientations shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the parts described must have a specific orientation, or be constructed or operated according to a specific orientation. Therefore, they should not be considered as limitations on the present invention.

[0024] like Figures 1 to 4 This invention discloses a forward viewing distance evaluation system based on a human-machine interface (HMI) test bench for different vehicle models and seating postures. By adjusting the positions of each device, the status of each device in the evaluation system can be adjusted to match the target vehicle model, allowing evaluators to perform forward viewing distance evaluations for that vehicle model. The evaluation system can be matched with different vehicle models (including sedans, SUVs, MPVs, crossovers, etc.), achieving coverage of different vehicle model statuses. After entering the evaluation system, the evaluator uses the seat's self-adjusting device to move X / Y / Z, then adjusts the fore-and-aft and up-and-down positions of the steering wheel, and combines this with the positions of the brake and accelerator pedals to continuously adjust and find a suitable seating posture. This evaluation system is adaptable to different groups of people and can meet the evaluation requirements of different human seating postures. After all devices are adjusted, the evaluator uses a remote control on the evaluation system to move the forward viewing distance measurement vehicle back and forth until the entire rear of the vehicle can be seen. The remote control can then stop the vehicle, and the forward viewing distance at this point will be displayed on the remote control, thus achieving the evaluation of the forward viewing distance of the target vehicle model.

[0025] The evaluation system includes a forward visibility measuring device 1, a basic frame device 4, a front cover device 2, an instrument panel device 3, a seat device 5, a pedal device 6, and a floor device 7.

[0026] like Figure 3 and Figure 4 The forward sight distance measuring device 1 includes a forward sight distance measuring carriage 11 and a ground scale 12. A ranging radar 111 is fixed on the forward sight distance measuring carriage 11. The ground scale 12 includes scale lines 121, scale start lines 122, projection lines of the foremost point of the front cover 123, and a remote controller 112. After adjusting the seat, the forward sight distance is measured by operating the remote controller 112 to control the forward sight distance measuring carriage 11 to move forward, backward, and stop.

[0027] In use, the evaluator controls the forward distance measuring vehicle 11 to move back and forth on the evaluation system via remote control 112 until the entire rear area of ​​the forward distance measuring vehicle 11 can be seen. The evaluator can then control the forward distance measuring vehicle 11 to stop via remote control 112. The forward distance will be displayed on the remote control 112 at this time, thus realizing the evaluation of the forward distance of the target vehicle model.

[0028] like Figure 5 The basic frame device 4 includes a front cover and dashboard fixing mechanism 41, a lateral fixing mechanism 42, a first connecting plate 411, and a seat and floor fixing mechanism 43. The front cover and dashboard fixing mechanism 41 is fixed to the first connecting plate 411 by bolts. The first connecting plate 411 is fixed to the lateral fixing mechanism 42 by bolts. The lateral fixing mechanism 42 is fixed to the seat and floor fixing mechanism 43 by bolts.

[0029] like Figures 6 to 7 In this embodiment, the front cover device 2 includes a front cover 21, a first Z-axis scale 22, a first guide rod 23, a first connecting rod 25, a first stepper motor 24, a first lead screw 26, a second connecting plate 211, a first fixing plate 281, a first scale fixing plate 221, a first lead screw motion mechanism 251, a first guide cylinder 27, and a first platform 28.

[0030] The front cover 21 is fixed to the upper end face of the second connecting plate 211 by bolts; one end (the upper end in this embodiment) of the first guide rod 23, the first Z-axis scale 22 and the first lead screw 26 are all fixed to the lower end face of the second connecting plate 211 by bolts, the other end (the lower end in this embodiment) of the first Z-axis scale 22 is fixed to the first scale fixing plate 221 by bolts, and the other ends of the first guide rod 23 and the first lead screw 26 are suspended.

[0031] The first fixing plate 281 is fixed to the first platform 28 by bolts, and the first fixing plate 281 is fixed to the front cover and instrument panel fixing structure 41 by bolts (e.g., Figure 9 The first guide rod 23 and the first guide cylinder 27 are in clearance fit, and the first guide rod 23 can slide up and down relative to the first guide cylinder 27. Thus, since the first guide cylinder 27 is fixedly connected to the first platform 28, the first platform 28 is fixedly connected to the first fixing plate 281, and the first fixing plate 281 is fixed to the front cover and instrument panel fixing structure 41, the fixing between the first guide cylinder 27 and the front cover and instrument panel fixing structure 41 is realized. The first guide rod 23 fixed on the second connecting plate 211 can move up and down relative to the first guide cylinder 27 together with the second connecting plate 211 and the front cover 21.

[0032] Combination Figure 7The first guide cylinder 27 is a cylindrical structure. One end of the first guide rod 23 passes through the guide plate 27 and extends outward from it, with a boss extending outward from its upper part. The first platform 28 is a plate-shaped structure, which is fitted onto the outside of the first guide cylinder 27 and the first lead screw 26. The boss extending outward from the upper part of the first guide cylinder 27 overlaps the upper surface of the first platform 28, and the first guide cylinder 27 is fixed to the first platform 28 by screwing the boss. Thus, the first stepper motor 24 drives the first connecting rod 25 to rotate, and the first lead screw motion mechanism 251 mounted on the first lead screw 26 converts the rotation of the first connecting rod 25 into the up and down movement of the first lead screw 26. The first lead screw 26 drives the second connecting plate 211 and the front cover 21 to move up and down, and the first guide rod 23 fixed on the second connecting plate 211 guides the front cover 21 to move up and down in the Z direction.

[0033] In this embodiment, in order to achieve synchronous movement of both sides of the front cover 21, a first lead screw 26, a first guide rod 23, a first guide cylinder 27, a first scale fixing plate 221, and a first lead screw motion mechanism 251 are symmetrically arranged on both sides of the front cover 21. The symmetrically arranged first lead screw motion mechanism 251 is connected by a first connecting rod 25. One end of the first connecting rod 25 passes through a first lead screw motion mechanism 251 and is assembled with a first stepper motor 24, so that it is driven by a first stepper motor 24.

[0034] In use, the evaluator can adjust the position of the front cover of the evaluation system to match the target vehicle model by controlling the first stepper motor 24.

[0035] like Figures 10 to 19 As shown, in this embodiment, the instrument panel device 3 includes: an instrument panel frame, a left instrument panel mechanism, a middle instrument panel mechanism, a right instrument panel mechanism, a steering wheel mechanism, a left instrument panel decorative piece, a middle instrument panel decorative piece, and a right instrument panel decorative piece. The left instrument panel mechanism, the middle instrument panel mechanism, and the right instrument panel mechanism are assembled on the instrument panel frame, while the steering wheel mechanism is assembled on the left instrument panel mechanism. The left instrument panel trim is mounted on the left instrument panel mechanism and can move in position along with the left instrument panel mechanism in the X direction parallel to the front-rear direction of the vehicle under test and in the Y direction parallel to the left-right direction of the vehicle under test; the middle instrument panel trim is mounted on the middle instrument panel mechanism and can move in position along with the middle instrument panel mechanism in the X direction parallel to the front-rear direction of the vehicle under test and in the Z direction parallel to the height Z direction of the vehicle under test; the right instrument panel trim is mounted on the right instrument panel mechanism and can move in position along with the right instrument panel mechanism in the X direction parallel to the front-rear direction of the vehicle under test and in the Y direction parallel to the left-right direction of the vehicle under test.

[0037] The third platform 3102 is arranged on the second platform 3101. One end of the third lead screw 3106 and the second guide rod 3107 are bolted to the third platform 3102, and the other end passes through the second platform 3101. That is to say, the third lead screw 3106 and the second guide rod 3107 are arranged along the Z direction.

[0038] The second guide rod 3107 passes through the second guide cylinder 3108 and then through the second platform 3101. The second guide cylinder 3108 is assembled with the second platform 3101 in a similar manner to the first guide cylinder 27. The second platform 3101 is fixedly connected to the front cover and instrument panel fixing mechanism 41 in the same manner as the first platform 28. Thus, the second stepper motor 3103 drives the second lead screw 3104 to move. The second lead screw 3104 drives the third lead screw 3106 to move through the worm gear transmission mechanism 3105. The third lead screw 3106 is fixed to the third platform 3102 with bolts. The third lead screw 3106 drives the third platform 3102 and the second guide rod 3107 to move Z-axis up and down relative to the second guide cylinder 3108, thereby realizing the Z-axis up and down movement of the entire instrument panel device 3.

[0039] In order to enable the third platform 3102 to move straight along the vertical direction, a strip tooth 3111 is fixed on the side edge of the second platform 3101 and the third platform 3102 along the vertical direction. A second guide rod 3112 is assembled on the lower edge of the second platform 3101 through a fixing block 3114. A roller 3113 is assembled on the second guide rod 3112. The strip tooth 3111 and the roller 3113 mesh. When the third platform 3102 moves along the Z direction, the strip tooth 3111 moves up and down relative to the roller 3113, thereby forming a Z-direction movement guide for the third platform 3102.

[0040] And, as Figure 10 As shown, a mounting block 3115 is installed at the lower end of the strip tooth 3111 arranged on both sides of the third platform 3102 and the second platform 3101, and the third lead screw 3106. The mounting block 3115 is used to fix the front cover, i.e., the instrument panel fixing mechanism 41.

[0041] The Z-axis displacement of the instrument panel device 3 can be measured by the first Z-axis measuring module 3109 and the second Z-axis scale 3110 mounted on the second platform 3101 and the third platform 3102. The first Z-axis measuring module 3109 and the second Z-axis scale 3110 are arranged on the side edges of the third platform 3102 and the second platform 3101.

[0042] In this embodiment, in order to achieve stability in the vertical movement of the third platform 3102, the aforementioned second lead screw 3104, third lead screw 3106, second guide rod 3107 and second guide cylinder 3108 are set as multiple sets, and multiple third lead screws 3106 are connected by connecting rods to achieve synchronous movement.

The first X-axis slide rail 3204 is assembled to the second left fixed platform 3202 along the X-axis of the vehicle via the first slider 32024. Simultaneously, the first X-axis slide rail 3204 is fixedly connected to the first left fixed platform 3202, and the first X-axis stepper motor 3203 is fixedly connected to the first left fixed platform 3201. The first X-axis stepper motor 3203 drives the fourth lead screw 3207 to rotate. Because the second mounting block 32022 is fixed to the second left fixed platform 3202, the first X-axis stepper motor 3203 moves in the X-axis direction. Since the first X-axis stepper motor 3203 is fixedly connected to the first left fixed platform 3201, the first X-axis stepper motor 3203 drives the first left fixed platform 3201 to move in the X-axis direction of the vehicle, while the first X-axis slide rail 3204 slides relative to the first slider 32024. The X-direction displacement can be measured by the first X-direction scale 3212 and the first X-direction measurement module 3213. The first X-direction scale 3212 is mounted on the aforementioned second horizontal plane fixing plate 3402, and the first X-direction measurement module 3213 is fixed on the aforementioned second left side fixing platform 3202.

[0048] The first Y-axis stepper motor 3205 drives the fifth lead screw 3208 to rotate. The rotation of the fifth lead screw 3208 causes the second left-side fixed platform 3202 to move in the Y-direction relative to the fifth lead screw 3208 along with the third mounting block 32023. The third left-side fixed platform 3209 on the second left-side fixed platform 3202 moves in the Y-direction along with it. The third left-side fixed platform 3209 drives the second slider 32061, which is fixedly connected to it, to move in the Y-direction along the first Y-direction slide rail 3206. Simultaneously, the first slider 32024 and the first X-direction slide rail 3204 on the second left-side fixed platform 3202 move in the Y-direction, thereby causing the first left-side fixed platform 3201 to move in the Y-direction as a whole. The Y-direction displacement can be measured by the first Y-direction scale 3210 and the first Y-direction measuring module 3211. The first Y-direction measuring module 3211 is mounted on the aforementioned third left-side fixed platform 3209, and the first Y-direction scale 3210 is mounted on the aforementioned third platform 3102.

[0049] like Figure 11 In this embodiment, the left instrument panel mechanism further includes a steering wheel mechanism fixing plate 3215 for assembling the steering wheel mechanism. The steering wheel mechanism fixing plate 3215 is mounted on the first left fixed platform 3201 via a horizontal plate.

[0050] like Figures 10 to 18In this embodiment, the intermediate instrument panel mechanism includes: an intermediate panel decorative piece 3301, a first intermediate fixed platform 3302, a first horizontal fixed plate 3303, a first vertical fixed plate 3304, a second X-axis stepper motor 3305, a second X-axis slide rail 3306, a sixth lead screw 3307, a second intermediate fixed platform 3308, a third X-axis stepper motor 3309, a third X-axis slide rail 3310, a seventh lead screw 3311, a Z-axis fixed platform 3312, a first Z-axis slide rail 3313, and an eighth lead screw 3314.

[0051] The center console decorative piece 3301 is used as a simulated in-vehicle central control entertainment screen.

[0052] The second intermediate fixed platform 3308 is fixed on the third platform 3102. A third slider 33082 is mounted on the second intermediate fixed platform 3308, and a third X-axis slide rail 3310 is mounted in the third slider 33082, allowing the third X-axis slide rail 3310 to move in the X direction relative to the third slider 33082. A fourth mounting block 33081 is also fixed on the second intermediate fixed platform 3308. A seventh lead screw 3311 connected to the third X-axis stepper motor 3309 passes through a mounting hole in the fourth mounting block 33081. In addition, a sixth mounting block 33091 is provided on the third X-axis stepper motor 3309, which is assembled with the first horizontal surface fixed plate 3303. The sixth mounting block 33091 is fixedly assembled with the first horizontal surface fixed plate 3303, and the second X-axis drive motor 3305 is fixedly assembled with the first horizontal surface fixed plate 3305 through the seventh mounting block 33051.

[0053] The first intermediate fixed platform 3302 is arranged on the second intermediate fixed platform 3308. The sixth lead screw 3307 connected to the second X-axis stepper motor 3305 passes through the hole in the fifth mounting block 33021 on the first intermediate fixed platform 3302. The second X-axis slide rail 3306 is fixed on the first intermediate fixed platform 3302. A fourth slider 33022 is mounted on the second X-axis slide rail 3306. The fourth slider 33022 can slide on the second X-axis slide rail 3306.

[0054] The end of the Z-direction fixed platform 3312 is fixed to the end of the second X-direction slide rail 3306, and the Z-direction fixed platform 3312 is arranged along the Z direction. The first Z-direction slide rail 3313 is installed on the Z-direction fixed platform 3312 along the Z direction. The first vertical surface fixed plate 3304 is installed on the first Z-direction slide rail 3313 through the fifth slider 33131. The first vertical surface fixed plate 334 is also fixed with an eighth lead screw 3314 connected to the rotating first handle 3315. The installation method of the eighth lead screw 3314 on the first vertical surface fixed plate 3304 is similar to the assembly method of the aforementioned seventh lead screw 3311 and sixth lead screw 3307.

[0055] Therefore, when the second X-axis stepper motor 3305 operates, the sixth lead screw 3307 rotates relative to the fifth mounting block 33021, and the fifth mounting block 33021 moves in the X-axis relative to the sixth lead screw 3307. This causes the first intermediate fixed platform 3302 to move in the X-axis, which in turn causes the second X-axis slide rail 3306 and the Z-axis fixed platform 3312 to move in the X-axis. Consequently, the first vertical fixed plate 3304 mounted on the Z-axis fixed platform 3312 moves in the X-axis along with it, causing the intermediate platform decorative piece 3301 fixed on the first vertical fixed plate 3304 to move in the X-axis. The X-axis displacement of the intermediate platform decorative piece 3301 can be measured by the second X-axis scale 3316 mounted on the first intermediate fixed platform 3302 and the second X-axis measuring module 3317 mounted on the first horizontal fixed plate 3303.

[0056] In addition, such as Figure 19 By rotating the first handle 3315, the eighth lead screw 3314 rotates, causing the Z-axis fixed platform 3312 to move in the Z direction. The Z-axis fixed platform 3312 moves up and down relative to the first Z-axis slide rail 3313 via the fifth slider 33131. As a result, the intermediate platform decorative piece 3301 mounted on the Z-axis fixed platform 3312 moves in the Z direction along with it. The Z-axis displacement can be measured by the third Z-axis scale 3318 mounted on the Z-axis fixed platform 3312 and the second Z-axis measuring module 3319 mounted on the first vertical surface fixed plate 3304.

[0057] When the third X-axis stepper motor 3309 operates, since the second intermediate fixed platform 3308 is in a fixed state, the seventh lead screw 3311 rotates relative to the fourth mounting block 33081, causing the third X-axis stepper motor 3309 to move in the X direction. The third X-axis stepper motor 3309 drives the first horizontal fixed plate 3303 to move in the X direction, and the intermediate instrument panel mounted on the first horizontal fixed plate 3303 moves in the X direction along with it. The first horizontal fixed plate 3303 drives the second X-axis stepper motor 3305 to move in the X direction, thereby driving the aforementioned intermediate panel decorative piece 3301 to move in the X direction. At this time, the intermediate instrument panel and the intermediate panel decorative piece 3301 move synchronously in the X direction. The X-axis displacement of the intermediate instrument panel can be measured by the third X-axis scale 3320 mounted on the second intermediate fixed platform 3308 and the third X-axis measuring module 3321 mounted on the first horizontal fixed plate 3303.

[0058] like Figures 20 to 26In this embodiment, the right instrument panel mechanism includes: a right panel decorative piece 3401, a second horizontal plane fixing plate 3402, a second vertical plane fixing plate 3403, a fourth X-axis stepper motor 3404, a fourth X-axis slide rail 3405, a ninth lead screw 3406, a panel decorative piece fixing plate 3407, a first right-side fixed platform 3408, a second Y-axis stepper motor 3409, a second Y-axis slide rail 3410, a tenth lead screw 3411, and a second right-side fixed platform 3412.

[0059] The second Y-axis slide rail 3410 and the second right-side fixed platform 3412 are arranged parallel to each other along the Y-direction of the vehicle, with the two second right-side fixed platforms 3412 positioned between the two second Y-axis slide rails 3410. An eighth mounting block 34121, a ninth mounting block 34122, and a tenth mounting block 34123 are provided on the second right-side fixed platform 34122. The eighth mounting block 34121 is used for mounting the first right-side fixed platform 3408, the ninth mounting block 34122 is used for the passage of the ninth lead screw 3406, and the tenth mounting block 34123 is used for the passage of the tenth lead screw 3411.

[0060] The second Y-axis slide rail 3410 is fixed on the aforementioned third platform 3102. The second right-side fixed platform 3412 is placed on the third platform 3102. A sixth slider 34101 is mounted on the second Y-axis slide rail 3410. The first right-side fixed platform 3408 is fixedly mounted on the sixth slider 34101 and the eighth mounting block 34121. One end of the ninth lead screw 3406 is connected to the fourth X-axis stepper motor 3404, and the other end passes through the mounting hole on the ninth mounting block 34122. One end of the tenth lead screw 3411 is connected to the second Y-axis stepper motor 3409, and the other end passes through the mounting hole on the tenth mounting block 34123.

[0061] The second Y-axis stepper motor 3409 drives the tenth lead screw 3411 to rotate. The rotation of the tenth lead screw 3411 causes the second right-side fixed platform 3412 to move in the Y-direction relative to the tenth lead screw 3411 along with the tenth mounting block 34123. This movement, along with the second horizontal fixed plate 3402 connected to the fourth X-axis slide rail 3405, causes the left-side platform decorative piece 3401 to move in the Y-direction. Simultaneously, the second right-side fixed platform 3412 drives the first right-side platform fixed platform 3408 to slide relative to the second Y-axis slide rail 3410 via the sixth slider 34101. The Y-direction displacement can be measured by the second Y-axis scale 3415 and the second Y-axis measuring module 3416. The second Y-axis measuring module 3416 is mounted on the aforementioned first right-side fixed platform 3408, and the second Y-axis scale 3415 is mounted on the aforementioned third platform 3102.

[0062] The fourth X-axis slide rail 3405 is mounted onto the second right-side fixed platform 3412 along the X-axis of the vehicle via the seventh slider 34124. The fourth X-axis stepper motor 3404 drives the ninth lead screw 3406 to rotate. Since the second right-side fixed platform 3412 is limited by the third platform 3102 and cannot move in the X-axis direction, the ninth lead screw 3406 reverses this movement, causing the fourth X-axis stepper motor 3404 to move in the X-axis direction. The fourth X-axis stepper motor 3404 then drives the connected second horizontal surface fixed plate 3402 to move in the X-axis direction. The second horizontal surface fixed plate 3402 then drives the connected fourth X-axis slide rail 3405 to move in the X-axis direction relative to the seventh slider 34124. This causes the ninth mounting block 34122 to move relative to the ninth lead screw 3406 in the X-axis direction of the vehicle, and the second right-side fixed platform 3412 moves relative to the fourth X-axis slide rail 3405 in the X-axis direction via the seventh slider 34124. The X-axis displacement can be measured by a fourth X-axis scale 3413 and a fourth X-axis measuring module 3414. The fourth X-axis scale 3413 is mounted on the aforementioned second horizontal plane fixing plate 3402, and the fourth X-axis measuring module 3414 is fixed on the aforementioned first right-side fixing platform 3408. The second horizontal plane fixing plate 3402 is mounted on the aforementioned first right-side fixing platform 3408 and moves in the X and Y directions together with the first right-side fixing platform 3408.

[0063] The second vertical fixing plate 3403 is fixedly assembled to the first horizontal fixing plate 3402 by a horizontal plate. A tabletop decorative fixing plate 3407 is assembled on the second vertical fixing plate 3403. The right-side tabletop decorative piece 3401 is fixed to the second horizontal fixing plate 3402 by bolts.

[0064] like Figures 34 to 36In this embodiment, the steering wheel mechanism is designed according to CN114858476B. The steering wheel mechanism in this embodiment includes: a steering wheel 3501, a steering lock housing 3502, a fixed platform 3503, a steering wheel fixing module 3504, and a third vertical surface fixing plate 3505. The steering wheel 3501 is fixed to the steering wheel fixing module 3504 by bolts. The steering wheel fixing module 3504 is fixed to the measuring module 3506 by bolts. The measuring module 3506 is fixed to the fixed platform 3503 via a sixth rotating shaft 3507. Manually moving the steering wheel 3501 allows for angle adjustment via the sixth rotating shaft 3507 fixed to the fixed platform 3503. 1. The angle adjustment amount can be measured by the scale 3508 and the measuring module 3506; 2. By opening the locking handle 3509 and moving the steering wheel 3501 back and forth, the fixed platform 3503 can move back and forth along the slide rail 3510, thus achieving the forward and backward movement of the steering wheel 3501. The amount of forward and backward movement can be measured by the scale 3511 and the measuring module 3512; 3. By opening the locking handle 3513 and manually moving the fixed platform 3503, the angle of the fixed platform 3503 can be adjusted by the seventh rotating shaft 3515 fixed on the sliding module 3514, thereby achieving the angle adjustment of the steering wheel 3501. The angle adjustment amount can be measured by the measuring module 3516 and the scale 3517. The manual rotation handle 3518 can drive the lead screw 3519 to move. The lead screw 3519 drives the second fixed plate 3520 to move up and down in the Z direction along the slide rail 3520. The scale 3521 is fixed on the second fixed plate 3521. The scale 3517 is mounted on the sliding module 3514 through the seventh rotating shaft 3515. The sliding module 3514 drives the fixed platform 3503 to move up and down in the Z direction through the slide rail 3510, thereby realizing the steering wheel 3501 moving up and down in the Z direction. The Z direction movement can be measured by the fifth Z direction scale 3521 and the fifth Z direction measuring module 3522. The manual rotation of the handle 3523 can drive the lead screw 3524 to move. The lead screw 3524 drives the third vertical surface fixed plate 3505 to move left and right in the Y direction along the slide rail 3525. The third fixed plate 3519 is fixed on the third vertical surface fixed plate 3505 through the fifth Y-direction slide rail 3520 to achieve left and right movement in the Y direction, thereby realizing the steering wheel 3501 to move left and right in the Y direction. The amount of Y-direction movement can be measured by the sixth Y-direction scale 3526.

[0065] When using the system, evaluators can adjust the positions of the instrument panel, steering wheel, and other components of the evaluation system to match the model of the vehicle being tested.

[0066] The seating device 5 includes a seating mechanism and a seating movement mechanism.

Pulling the second handle 5105 allows the seat to move forward and backward along the seat slide rail 5101 in the X direction. Pulling the third handle 5106 allows the seat to move up and down in the Z direction. Pulling the fourth handle 5107 allows the seat back 5103 to be adjusted in angle.

The fixing platform 5201 is fixedly connected to the fifth X-axis slide rail 5205. The fixing module 52011 and the fifth X-axis slide rail 5205 are both fixed to the seat fixing platform 5201 by bolts. The flat plate 5211 is placed on the platform 5216 (and is limited by the platform 5216 in the X-axis and cannot move, but can move in the Y-axis). The fifth X-axis slide rail 5205 can move in the X-axis along the first sliding module 52051. The third Y-axis slide rail 5206 is fixed on the platform 5216.

[0070] X-axis motion: The fifth X-axis stepper motor 5202 drives the eleventh lead screw 5210 to rotate. The eleventh lead screw 5210 is threadedly connected to the first fixing module 52011. The first fixing module 52011 can achieve X-axis linear movement through the threaded transmission with the eleventh lead screw 5210. That is, the rotational motion of the eleventh lead screw 5210 is converted into the X-axis motion of the first fixing module 52011 through the threaded transmission. The first fixing module 52011 drives the seat fixing platform 5201 and the fifth X-axis slide rail 5205 to move in the X-axis along the first sliding module 52051, thereby realizing the X-axis motion of the seat mounted on the seat fixing platform 5201. The amount of X-axis motion of the seat can be quantitatively measured by the fifth X-axis scale 5218 and the fifth X-axis measuring module 5219.

[0071] Y-axis motion: The second fixed module 5213, the third Y-axis measuring module 5220, and the first sliding module 52051 are all fixed to the plate 5211 by bolts.

The third Y-axis stepper motor 5203 drives the twelfth lead screw 5212 to rotate. The twelfth lead screw 5212 and the second fixed module 5213 are connected by threads, which are in clearance fit, and can realize threaded transmission. Through threaded transmission, the rotational motion of the twelfth lead screw 5212 can be converted into linear Y-axis motion of the second fixed module 5213. The second fixing module 5213 drives the plate 5211 to move in the Y direction. The plate 5211 drives the first sliding module 52051 to move. The first sliding module 52051 drives the seat fixing platform 5201 fixed on the first sliding module 52051 to move in the Y direction along the third Y direction slide rail 5206, thereby realizing the Y direction movement of the seat. The amount of Y direction movement of the seat can be quantitatively measured by the third Y direction scale and the third Y direction measuring module 5220.

[0072] Z-axis movement: The second fixed platform 5214 is fixed to the seat and floor fixing structure 43 via the third fixed module 5215. The thirteenth lead screw 5217 is fixed to the platform 5216 via a rotating disk and bolts. The third stepper motor 5204 drives the thirteenth lead screw 5217 to move via a worm gear transmission. The thirteenth lead screw 5217 drives the second fixed platform 5214 to move up and down in the Z-axis along the second guide rod 5207. The thirteenth lead screw 5217 is fixed to the platform 5216. The platform 5216 drives the seat fixing platform 5201 to move in the Z-axis, thereby realizing the Z-axis movement of the seat. The Z-axis displacement of the seat can be measured by the third Z-axis scale 5221 (connected to the third fixed module 5215 and the platform 5216) and the second Z-axis measuring module 5222 (assembled on the second fixed platform 5214).

[0073] When in use, evaluators can adjust the seat position of the evaluation system to match the target vehicle model using the method described.

[0087] The eighth X-axis stepper motor 79 drives the twenty-first lead screw 76 to move. The twenty-first lead screw 76 drives the third fixed platform 73 to move forward and backward along the eighth X-axis slide rail 78 through the fixed module 725, thereby realizing the X-axis movement of the floor 72. The amount of X-axis movement of the floor 72 can be measured by the eighth X-axis scale 728 and the eighth X-axis measurement module 727.

[0088] Rotating the fifth handle 714 can drive the sixth sliding module 713 to move in the X direction along the first slide groove 724, thereby realizing the X-direction movement of the footrest 71. The X-direction movement displacement can be measured by the ninth X-direction scale 718.

[0090] Stepping on the footrest board allows the footrest board 71 to be angled along the slide groove 731 via the fifth rotating shaft 717. The angle adjustment amount can be measured by the third angle scale 711 and the third angle measuring module 712.

[0091] When in use, evaluators can adjust the positions of the floor and footrest of the evaluation system to match the target vehicle model using the methods described above.

[0092] The above seven devices together constitute the forward visibility evaluation system, which can evaluate different vehicle models (including sedans, SUVs, MPVs, crossovers, etc.) and different human sitting postures. The evaluation of forward visibility is more objective and convenient. At the same time, during the vehicle development process, the system such as the front hood height, instrument panel height, and floor height can be corrected and adjusted in a timely manner. After the adjustment, a new round of forward visibility evaluation can be carried out until the forward visibility design requirements of vehicle development are met. The timeliness and convenience of forward visibility design shorten the vehicle design and development time.
