Description

Technical Field

[0001] This invention belongs to the field of automotive roof manufacturing technology, and in particular to an automotive roof ergonomic verification device. Background Technology

[0002] As competition in the automotive market intensifies, consumers are placing increasing demands on driving comfort, and interior space directly impacts their perception of the vehicle. During automotive development, headroom is paramount, with the height and size of the roof directly influencing the overall sense of spaciousness. Therefore, verifying the roof's height, size, and sunroof's openness in advance is crucial, directly affecting whether the final product's space meets user requirements.

[0003] The inventors discovered that Chinese invention patent application CN 114894497 A discloses a flexible roof device for evaluating head space in automotive ergonomics. The overall structure is relatively complex, and the structural adjustment range of the roof device in this technical solution is small, making it difficult to adapt to various vehicle heights. Furthermore, its level of intelligence is low, making it unsuitable for current vehicle development.

[0004] In addition, Chinese authorized invention patent with announcement number CN 111442932 B discloses a car roof comfort verification device. This patented technology adopts a roof adjustment unit mounting bracket structure and can perform three-way adjustment using the roof adjustment unit mounted on the roof adjustment unit mounting bracket. The roof vertical adjustment unit consists of a roof vertical adjustment motor, a roof vertical adjustment motor mounting bracket, a roof vertical adjustment motor end shaft auxiliary bracket, a roof vertical adjustment motor end bearing seat, a roof vertical adjustment shaft, a roof vertical adjustment shaft auxiliary rod, a roof vertical adjustment shaft sleeve, a roof vertical adjustment shaft auxiliary rod sleeve, a roof vertical adjustment unit base plate, a roof vertical adjustment far end bearing seat, and a roof vertical adjustment far end shaft auxiliary bracket.

[0005] The inventors discovered that the aforementioned patented technology still has the following shortcomings:

[0006] (1) Although the above patent breaks through the limitations of the frame shape and adopts the top cover adjustment unit mounting bracket structure, when adjusting longitudinally, since the stroke of longitudinal adjustment is concentrated on the top cover vertical adjustment unit, the top cover vertical adjustment shaft and the top cover vertical adjustment shaft auxiliary rod are used as guides to adjust the longitudinal stroke. When it makes large-span adjustment, the stability and integration of the movement are not good.

[0007] (2) The above patent only shows a set of rear roof lateral adjustment units and front roof lateral adjustment units, which are driven and adjusted by the vertical adjustment unit base plate frame bracket, roof longitudinal adjustment unit, and roof vertical adjustment unit. However, when the vehicle roof needs to undergo a large-scale and large-span comfort test, the above patent technology is not very applicable, and the linkage between the various components is low. A large number of driving and driven components need to be deployed to achieve a large-scale and large-span test of the roof. Summary of the Invention

[0008] The purpose of this invention is to provide an ergonomic verification device for automobile roofs, which is suitable for large-scale and wide-span comfort testing scenarios of vehicle roofs. When adjusting the longitudinal space, the Z-direction displacement is decomposed into two parts: overall Z-direction adjustment and local Z-direction adjustment. The overall structure has high integration, good motion stability, and strong linkage between various components, thus solving the problems in the prior art.

[0009] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0010] This invention relates to an ergonomic verification device for an automobile roof, comprising a support frame and a canopy disposed on top of the support frame. The support frame is equipped with a Z-axis overall adjustment mechanism. The canopy is provided with multiple sets of roof simulation modules arranged along the X-axis. Each set of roof simulation modules includes an X-axis adjustment mechanism, a Y-axis adjustment mechanism, a Z-axis partial adjustment mechanism, and a simulated roof, wherein:

[0011] The Z-axis overall adjustment mechanism is used to drive the ceiling to perform overall Z-axis adjustment;

[0012] The X-axis adjustment mechanism and the Y-axis adjustment mechanism are used to drive the simulated top cover of the corresponding top cover simulation module to perform X-axis and Y-axis adjustments, respectively.

The X-axis lead screw and the X-axis nut are rotatably connected.

[0017] As an optional technical solution, the X-axis adjustment mechanism further includes an X-axis auxiliary slider, which is disposed on both sides of the upper plate. An X-axis auxiliary slide rail is also provided on the ceiling, and the X-axis auxiliary slider is slidably connected to the X-axis auxiliary slide rail.

[0018] As an optional technical solution, the Y-axis adjustment mechanism includes a Y-axis motor and a Y-axis transmission mechanism. The Y-axis transmission mechanism includes a Y-axis lead screw and a Y-axis nut. The Y-axis motor is mounted on the lower plate. The Y-axis lead screw is connected to the output shaft of the Y-axis motor. The Y-axis nut is mounted on the first connecting member. The Y-axis lead screw and the Y-axis nut are rotatably connected.

[0019] As an alternative technical solution, the Y-axis adjustment mechanism further includes a first rack, a second rack, and a gear. The first rack is disposed on a first connecting member, the second rack is disposed on a second connecting member, and the gear is rotatably connected to the lower surface of the lower plate. The first rack and the second rack mesh with the gear respectively.

[0020] As an optional technical solution, the Z-axis overall adjustment mechanism includes a first Z-axis motor and a first lifting transmission mechanism, wherein the first Z-axis motor is connected to the first lifting transmission mechanism and the first lifting transmission mechanism is connected to the support frame; the Z-axis partial adjustment mechanism includes a second Z-axis motor and a second lifting transmission mechanism, wherein the second Z-axis motor is disposed on the upper plate and is connected to the second lifting transmission mechanism, and the second lifting transmission mechanism is connected to the middle plate;

[0021] There are two second lifting transmission mechanisms, which are connected by a coupling.

[0022] As an alternative technical solution, an angle adjustment mechanism is also included. The angle adjustment mechanism includes an angle adjustment motor, an angle adjustment connector, and an angle sensor. The angle adjustment connector includes a fixing plate and two connecting ears disposed on the fixing plate. The angle adjustment motor is disposed at the bottom of the middle layer plate, and the output shaft of the angle adjustment motor passes through the two connecting ears and is connected to the angle sensor. The fixing plate of the angle adjustment connector is connected to the lower layer plate.

[0023] As an optional technical solution, both the first connecting member and the second connecting member include an upper connecting plate, a lower connecting plate, and a crossbeam. The crossbeam is disposed on the upper part of the upper connecting plate, and the lower connecting plate is disposed on the lower part of the upper connecting plate. The first profile or the second profile is disposed on the lower part of the lower connecting plate. The upper connecting plate and the lower plate are connected by the crossbeam. The Y-direction nut, the first rack, and the second rack are all connected to the edge of the upper connecting plate.

[0024] The present invention has the following beneficial effects:

[0025] 1. This invention provides an ergonomic verification device for automobile roofs, suitable for large-scale and wide-span comfort testing scenarios of vehicle roofs. By setting a Z-axis overall adjustment mechanism on the support frame and a Z-axis local adjustment mechanism on each roof simulation module, the Z-axis displacement is decomposed into the Z-axis overall adjustment mechanism and the Z-axis local adjustment mechanism during longitudinal spatial adjustment of the verification device. Large-scale, long-stroke, and wide-span longitudinal adjustment is achieved through the overall Z-axis adjustment and the local Z-axis adjustment, while the longitudinal adjustment has good stability.

[0026] 2. The present invention can first drive the roof to make overall Z-axis adjustment through the Z-axis overall adjustment mechanism, and then use the Z-axis local adjustment mechanism to drive the simulated roof of the corresponding roof simulation module to make local Z-axis adjustment. The two are combined to achieve precise adjustment of the longitudinal height through the overall + local adjustment method.

[0027] 3. The present invention has a high degree of overall structural integration, good motion stability, and strong linkage between various components. By rationally arranging the upper, middle, and lower plates, the X-axis adjustment mechanism drives the whole to perform X-axis adjustment; the Z-axis local adjustment mechanism arranged on the upper plate enables the middle plate, lower plate, and the simulated top cover connected thereto to perform Z-axis local adjustment; and through reasonable size arrangement, the Y-axis adjustment mechanism enables the Y-axis adjustment of the first top cover assembly, and the Y-axis adjustment of the first top cover assembly drives the Y-axis adjustment of the second top cover assembly, thereby reducing the number of drive motors and achieving linkage between multiple components.

[0028] 4. The present invention also realizes the angle adjustment between the lower plate and the middle plate through an angle adjustment mechanism. By connecting the angle adjustment motor to the angle adjustment connector, the lower plate drives the first top cover assembly or the second top cover assembly on it as a whole to adjust the angle relative to the middle plate.

[0029] 5. The canopy of the present invention is provided with multiple sets of top cover simulation modules arranged along the X direction. Each top cover simulation module includes a first top cover component and a second top cover component. The first top cover component and the second top cover component are arranged side by side along the Y direction, thereby increasing the adjustment range and making the present invention more suitable for overall range adjustment of XYZ directions and angles with large range, large stroke and large span.

[0030] 6. Through the rational layout of the overall structure, the present invention makes the angle adjustment and Y-axis adjustment functional components compact, each performing its own function without interfering with each other, thereby improving the integration and movement stability of the device.

[0031] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0048] Example 1:

[0049] Because the existing automotive roof verification device has a relatively concentrated range of longitudinal adjustment strokes, which are all concentrated on the Z-axis adjustment device, and as an easily conceived specific structural form, it often uses a longitudinally set screw and nut mechanism to adjust the longitudinal height. When it makes large-span adjustments, the stability of the movement is poor, and it is easy to wobble and move unstably.

[0050] Furthermore, existing solutions are not very applicable when the vehicle roof needs to undergo extensive comfort testing. The XYZ adjustment range of the vehicle roof is limited, or the XYZ adjustment is restricted by the external frame (as described in the background section). Moreover, the linkage between various components is low and the integration is poor. Even if the existing solutions are effectively extended, a large number of driving and driven components are required to achieve extensive testing of the roof.

[0051] To resolve the above technical issues, please refer to Figure 1 and Figure 2 As shown, as a specific implementation method, this embodiment discloses an automotive roof ergonomic verification device. The various modules have been redesigned, and the Z-axis adjustment stroke is decomposed into the Z-axis overall adjustment mechanism 3 and the Z-axis local adjustment mechanism 7, making the overall adjustment process more stable. At the same time, the specific XYZ and angle adjustment forms of each roof simulation module 4 on the roof 2 structure have been changed, improving the overall integration of the device, enhancing the linkage of multiple components, and making the overall structure more compact and concise.

[0052] like Figure 1 The diagram shown is a schematic of the overall structure of the support frame 1 in its unextended state. Figure 2 This is a schematic diagram of the support frame 1 in its extended state. This embodiment may include a support frame 1 and a canopy 2 disposed on top of the support frame 1. The support frame 1 is equipped with a Z-axis overall adjustment mechanism 3; the canopy 2 is equipped with multiple sets of roof simulation modules 4 arranged along the X-axis. Each set of roof simulation modules 4 includes an X-axis adjustment mechanism 5, a Y-axis adjustment mechanism 6, a Z-axis partial adjustment mechanism 7, and a simulated roof 8, wherein:

[0053] Z-axis overall adjustment mechanism 3 is used to drive the canopy 2 to perform overall Z-axis adjustment;

[0054] The X-axis adjustment mechanism 5 and the Y-axis adjustment mechanism 6 are used to drive the simulated top cover 8 of the corresponding top cover simulation module 4 to perform X-axis and Y-axis adjustments, respectively.

[0055] Z-axis local adjustment mechanism 7 is used to drive the simulated top cover 8 of the corresponding top cover simulation module 4 to perform local Z-axis adjustment.

[0056] It is understood that in order to provide good support for the roof 2 and make its stress more even, multiple support legs are provided at the bottom of the roof 2, and the multiple support legs together form the support frame 1 structure; each support leg includes a frame 40, which is located at the bottom and can provide stable support for the entire device. The frame 40 has a large mass and a low center of gravity, thereby improving the stability of the device during the adjustment process.

[0057] The Z-axis overall adjustment mechanism 3 in this embodiment includes a first Z-axis motor 28 and a first lifting transmission mechanism 29. The first lifting transmission mechanism 29 is a worm gear transmission mechanism. The first Z-axis motor 28 drives the worm, and the worm and worm gear are connected by transmission to realize the rotation of the worm gear, which in turn drives the lead screw nut mechanism to rotate, thereby realizing the lifting of the canopy 2.

[0058] The Z-axis overall adjustment mechanism 3 in this embodiment can be a product of the prior art. This embodiment does not impose any restrictions on it. For example, in this embodiment, the worm gear lifting mechanism of the prior art is selected.

[0059] In this embodiment, the canopy 2 structure is equipped with multiple tracks, with designated spaces between the tracks. This design serves two purposes: first, to reduce the weight of the canopy 2, and second, to provide guide tracks for the X-axis adjustments, thereby improving stability during X-axis adjustments. Specifically, as follows... Figure 3 and Figure 4 As shown, the overall structure of multiple sets of top cover simulation modules 4 and the structure of a single set of top cover simulation modules 4 are illustrated. In order to improve practicality, the specific structure of each set of top cover simulation modules 4 in this embodiment is the same.

[0060] from Figure 3 As can be seen, the canopy 2 is provided with multiple sets of roof simulation modules 4 arranged along the X direction. Each set of roof simulation modules 4 includes an X-direction adjustment mechanism 5, a Y-direction adjustment mechanism 6, a Z-direction local adjustment mechanism 7, and a simulated roof 8. The simulated roof 8 includes a first roof assembly 9 and a second roof assembly 10. The first roof assembly 9 and the second roof assembly 10 are arranged side by side along the Y direction. The reason for this arrangement is to increase the adjustment range, making this embodiment more suitable for the overall range adjustment of XYZ directions and angles with a large range, large stroke, and large span.

[0061] By adjusting the X-axis, Y-axis, and Z-axis directions of each set of top cover simulation modules 4 through the X-axis adjustment mechanism 5, Y-axis adjustment mechanism 6, and Z-axis local adjustment mechanism 7, the adjustment can be made more flexible. Multiple sets of top cover simulation modules 4 can adjust their respective XYZ three-axis ranges, thus expanding the adjustment range value.

[0062] Please combine Figure 5 As shown, the top cover simulation module 4 in this embodiment adopts a layered design, generally including an upper layer, a middle layer, a lower layer, and a simulated top cover 8, for a total of four layers. The specific connection relationships of the four layers will be described in detail below:

[0063] The first top cover assembly 9 of the simulated top cover 8 includes a first connector 11 and a first profile 12, the first profile 12 being disposed on the lower surface of the first connector 11; the second top cover assembly 10 includes a second connector 13 and a second profile 14, the second profile 14 being disposed on the lower surface of the second connector 13.

[0064] The simulated top cover 8 includes an upper plate 15, a middle plate 16 and a lower plate 17 arranged sequentially from top to bottom. The upper plate 15 and the middle plate 16 are movably connected along the Z direction. The middle plate 16 and the lower plate 17 are connected at an adjustable angle. The two ends of the lower plate 17 are connected to the first connecting member 11 and the second connecting member 13, respectively.

[0065] Through the overall connection method described above, the connection of the above four-layer structure is realized, and the X-axis adjustment mechanism 5 drives the upper plate 15, middle plate 16, lower plate 17 and simulated top cover 8 to perform X-axis adjustment as a whole; during Z-axis local adjustment, the upper plate 15 remains stationary, and the middle plate 16, lower plate 17 and simulated top cover 8 are adjusted in the Y-axis by the Z-axis local adjustment mechanism 7; the angle-adjustable connection between the middle plate 16 and the lower plate 17 can be achieved by the angle adjustment mechanism 33 driving the lower plate 17 and the simulated top cover 8 connected thereto to perform angle adjustment as a whole, realizing the angle adjustment of the lower plate 17 and the simulated top cover 8 connected thereto relative to the middle plate 16; in addition, during Y-axis adjustment, the Y-axis motor 22 on the lower plate 17 can drive the first top cover assembly 9, and the first top cover assembly 9 drives the second top cover assembly 10 to move simultaneously closer or further away in the Y-axis, thereby realizing the simultaneous approach or departure of the first top cover assembly 9 and the second top cover assembly 10 connected to the lower plate 17.

[0066] X-axis adjustment mechanism 5:

[0067] In a specific implementation, in this embodiment, as follows: Figure 4 and Figure 5 As shown, the X-axis adjustment mechanism 5 includes an X-axis motor 18 and an X-axis transmission mechanism. The X-axis transmission mechanism includes an X-axis lead screw 19 and an X-axis nut 20. The X-axis motor 18 and its mounting are mounted on the ceiling 2. The X-axis lead screw 19 is connected to the output shaft of the X-axis motor 18. The X-axis nut 20 is located at the center of the upper plate 15. The X-axis lead screw 19 and the X-axis nut 20 are rotatably connected. This allows the X-axis adjustment of the upper plate 15, middle plate 16, lower plate 17, and simulated top cover 8 as a whole to be driven by the X-axis adjustment mechanism 5.

[0068] To ensure greater stability during movement, the X-axis adjustment mechanism 5 also includes an X-axis auxiliary slider 21. The X-axis auxiliary slider 21 is located on both sides of the upper plate 15, and an X-axis auxiliary slide rail is also provided on the ceiling 2. The X-axis auxiliary slider 21 is slidably connected to the X-axis auxiliary slide rail. For details, please refer to [link to relevant documentation]. Figure 3 , Figure 4 and Figure 5 As shown.

[0069] Z-axis overall adjustment mechanism 3:

[0070] like Figure 4and Figure 5 As shown, the Z-axis local adjustment mechanism 7 includes a second Z-axis motor 30 and a second lifting transmission mechanism 31. The second Z-axis motor 30 is mounted on the upper plate 15 and is connected to the second lifting transmission mechanism 31. The second lifting transmission mechanism 31 is connected to the middle plate 16. There are two second lifting transmission mechanisms 31, and the two second lifting transmission mechanisms 31 are connected by a coupling 32.

[0071] In this embodiment, the second lifting transmission mechanism 31 can be selected to have the same structure as the first lifting transmission mechanism 29, both of which can adopt a worm gear transmission mechanism. In order to reduce the number of drive motors, the two second lifting transmission mechanisms 31 in this embodiment are connected by a coupling 32. Both second lifting transmission mechanisms 31 can be driven by a single second Z-axis motor 30, which saves on the number of motors while ensuring the stability of the local adjustment motion in the Z-axis.

[0072] The second lifting transmission mechanism 31 includes a worm and a worm wheel. The worm is connected to the output end of the second Z-axis motor 30, and the worm wheel meshes with the worm. When the second Z-axis motor 30 is running, the worm rotates and drives the worm wheel to rotate, thereby driving the screw nut mechanism to convert the rotational motion into linear motion, realizing local adjustment in the Z-axis.

[0073] Angle adjustment mechanism 33:

[0074] like Figure 6 , Figure 10 and Figure 11 As shown, this embodiment also includes an angle adjustment mechanism 33, which includes an angle adjustment motor 34, an angle adjustment connector 35, and an angle sensor 36. The angle adjustment connector 35 includes a fixing plate 42 and two connecting ears 41 disposed on the fixing plate 42. The angle adjustment motor 34 is disposed at the bottom of the middle plate 16, and the output shaft of the angle adjustment motor 34 passes through the two connecting ears 41 and is connected to the angle sensor 36. The fixing plate 42 of the angle adjustment connector 35 is connected to the lower plate 17.

[0075] Angle adjustment motor 34 is fixedly connected to the bottom of middle plate 16. Holes are reserved on two connecting ears 41. The output shaft of angle adjustment motor 34 passes through the holes of connecting ears 41 and is connected to angle sensor 36, so that the rotation angle of angle adjustment motor 34 can be measured by angle sensor 36.

[0076] The connecting ear 41 is fixedly connected to the lower plate 17 via the fixing plate 42 at the lower part of the connecting ear 41. This allows the angle adjustment motor 34 to rotate synchronously, driving the connecting ear 41 to rotate synchronously, which in turn drives the fixing plate 42, which in turn drives the lower plate 17 to rotate synchronously. Ultimately, the lower plate 17 is connected to the first connecting member 11 of the first top cover assembly 9 or the second connecting member 13 of the second top cover assembly 10 (e.g., ...). Figure 4 and Figure 5 As shown), the angle adjustment motor 34 adjusts the angle of the first surface 12 and the second surface 14.

[0077] Y-axis adjustment mechanism 6:

[0078] Please see Figure 7 , Figure 8 and Figure 9 As shown, where Figure 7 This is a schematic diagram of the overall structure of the Y-axis adjustment mechanism 6. Figure 8 This is a schematic diagram showing the structure of the Y-axis adjustment mechanism 6 and the angle adjustment mechanism 33, which are hidden behind the lower plate 17. Figure 9 This is a schematic diagram of the Y-axis adjustment mechanism 6 and the angle adjustment mechanism 33 from a bottom view.

[0079] The Y-axis adjustment mechanism 6 includes a Y-axis motor 22 and a Y-axis transmission mechanism. The Y-axis transmission mechanism includes a Y-axis lead screw 23 and a Y-axis nut 24. The Y-axis motor 22 is mounted on the lower plate 17. The Y-axis lead screw 23 is connected to the output shaft of the Y-axis motor 22. The Y-axis nut 24 is mounted on the first connecting member 11, specifically on the upper connecting plate 37 of the first connecting member 11. The Y-axis lead screw 23 and the Y-axis nut 24 are rotatably connected. Through the transmission of the Y-axis lead screw 23 and the Y-axis nut 24, when the Y-axis motor 22 is running, it will drive the entire first top cover assembly 9 to perform Y-axis adjustment through the first connecting member 11.

[0080] To improve the overall linkage and integration of the device, and to minimize the number of active drive devices, in this embodiment, the second top cover assembly 10 is driven by the first top cover assembly 9, and no additional active drive assembly is provided for the second top cover assembly 10. Specifically, the Y-axis adjustment mechanism 6 also includes a first rack 25, a second rack 26, and a gear 27. The first rack 25 is disposed on the first connecting member 11, the second rack 26 is disposed on the second connecting member 13, and the gear 27 is rotatably connected to the lower surface of the lower plate 17. The first rack 25 and the second rack 26 mesh with the gear 27 respectively.

[0081] It can be understood that, such as Figure 9As shown, the first rack 25 and the second rack 26 are respectively disposed on both sides of the gear 27. When the first connecting member 11 drives the Y-axis adjustment, it will drive the first rack 25 to move in the Y-axis. Since the first rack 25 meshes with the gear 27, the gear 27 will rotate under the drive of the first rack 25. After the gear 27 rotates, since the second rack 26 also meshes with the gear 27 at the same time, it will drive the second rack 26 to move in the Y-axis. The second connecting member 13 drives the second top cover assembly 10 to finally realize the Y-axis adjustment.

[0082] The first connecting member 11 and the second connecting member 13 both include an upper connecting plate 37, a lower connecting plate 38, and a crossbeam 39. The crossbeam 39 is disposed on the upper part of the upper connecting plate 37, the lower connecting plate 38 is disposed on the lower part of the upper connecting plate 37, and the first profile 12 or the second profile 14 is disposed on the lower part of the lower connecting plate 38. The upper connecting plate 37 and the lower plate 17 are connected by the crossbeam 39. The Y-direction nut 24, the first rack 25, and the second rack 26 are all connected to the edge of the upper connecting plate 37.

[0083] like Figure 7 and Figure 8 As shown, the crossbeam 39 is fixedly connected to the bottom of the lower plate 17, and holes are provided at both ends of the crossbeam 39; columnar sliders are provided at both ends of the upper surface of the upper connecting plate 37, and the sliders pass through the holes at both ends of the crossbeam 39, and the sliders are slidably connected to the crossbeam 39. The advantage of this arrangement is that when adjusting the first top cover assembly 9 and the second top cover assembly 10 in the Y direction, it is easier to control the stability of the Y-direction movement, making the movement smoother.

[0084] Figure 8 The image also shows parts of the structure of the angle adjustment mechanism 33 and the Y-axis adjustment mechanism 6. Figure 8 The relative positional relationship between the angle adjustment mechanism 33 and the Y-axis adjustment mechanism 6 can be seen from this.

[0085] like Figure 12 As shown, this embodiment also provides an intelligent control system for an automotive roof ergonomic verification device. It can be understood that the intelligent control system of this embodiment includes: an industrial control computer, electrical control software, a motor signal processing system, and a sensor signal processing system. The electrical control software sends instructions to the industrial control computer, which receives the signals and sends them to the corresponding motor. The motor then transmits its position signal back to the electrical control software, thus achieving a precise and intelligent control system.

[0086] This system has the advantages of fast, efficient and comprehensive verification. Due to its large lifting mechanism, it can be combined with an optical motion capture system without obstructing the optical motion capture system signal, and can simultaneously perform subjective evaluations of the virtual and physical interior space of a car.

[0087] This embodiment can meet the headroom verification requirements of passenger vehicles developed on multiple platforms. The roof 2 is electrically adjustable via software, making verification convenient, fast, and comprehensive. By adjusting the roof 2 frame mechanism over a large span, the height verification range of the car roof 2 is increased from the conventional 200mm to a height bandwidth of 1000mm. All adjustments to the roof 2 are motor-driven, and the intelligent control software allows for precise control of the roof 2's position.

[0088] Working principle:

[0089] When the four sets of electric worm gears of the large-span adjustable roof 2 frame mechanism are energized, the four sets of worm gears rise and fall, driving the overall roof 2 frame mechanism to rise and fall. The designed height travel is 1100mm, which can cover the height adjustment of the roof 2 for all vehicle sizes.

[0090] The top cover simulation module 4 is fixed on the overall lifting mechanism frame and can rise and fall together with the overall lifting mechanism; at the same time, each simulated top cover 8 can also be individually adjusted in XYZ and angle.

[0091] The X-axis adjustment mechanism 5 adopts an electric linear slide rail slider structure, with the slide rail fixed to the frame mechanism of the canopy 2. When the X-axis motor 18 is powered on, the lead screw rotates, driving the entire mechanism to slide forward and backward X-axis through the connecting nut.

[0092] The Z-axis adjustment mechanism uses one motor to drive two sets of worm gear mechanisms. When the second Z-axis motor 30 is energized, the worm rotates, causing the mechanism to move up and down. The two worm gears are connected by a coupling 32.

[0093] The Y-axis adjustment mechanism 6 adopts a set of lead screw and nut mechanism in conjunction with electric gear 27 rack mechanism. When the motor is powered on, the lead screw and nut mechanism drives the first top cover assembly 9 on one side to move in the Y direction; then the Y-axis movement of the first top cover drives the gear 27 to rotate, so that the rack drives the second top cover assembly 10 on the other side to move in the Y direction.

[0094] The angle adjustment mechanism 33 adopts an electric structure. After the motor is powered on, it drives the first surface 12 and the second surface 14 to rotate electrically.

[0095] In this embodiment, universal bolt holes are provided on the lower connecting plate 38, which allows for quick replacement of the profile.
