[0031] The present invention will now be described in detail with reference to the accompanying drawings, which form part of this specification. The principles of the invention are illustrated by means of embodiments, and other aspects, features, and advantages of the invention will become apparent from this detailed description. In the accompanying drawings, the same or similar parts in different figures are indicated by the same reference numerals.

[0032] like Figures 1-11As shown, Embodiment 1 of the present invention provides an adjustment and positioning device for the seat position in a car verification model. The adjustment and positioning device includes a lifting platform 1, a Z-axis lifting structure 2, an X-axis adjustment structure 3, two sets of Y-axis moving structures 4, and a seat support platform 6 for fixing the car verification model seat. The Z-axis lifting structure 2 is fixed below the lifting platform 1. The X-axis adjustment structure 3 and the two sets of Y-axis moving structures 4 are all fixed above the lifting platform 1. The two sets of Y-axis moving structures 4 are symmetrically fixed above the X-axis adjustment structure 3. The seat support platform 6 is fixed at the upper end of the two sets of Y-axis moving structures 4. A Y-axis drive structure 5 is connected between the two sets of Y-axis moving structures 4. The Z-axis lifting structure 2 drives the lifting platform 1 and the X-axis adjustment structure 3, the two sets of Y-axis moving structures 4, and the seat support platform 6 to move along the Z-axis. The X-axis adjustment structure 3 drives the Y-axis moving structures 4 and the seat support platform 6 to move along the X-axis. The Y-axis drive structure 5 drives the two sets of Y-axis moving structures 4 to slide synchronously, thereby driving the seat support platform 6 to move along the Y-axis. The adjustment and positioning device of this invention, through the coordinated action of the Z-axis lifting structure 2, the X-axis adjustment structure 3, and two sets of Y-axis adjustment structures, enables the seat support platform 6 to move along three dimensions: the Z-axis (up and down), the X-axis (left and right), and the Y-axis (front and back). Position adjustment can be completed without disassembling the seat, shortening adjustment time and enabling rapid seat position adjustment. This significantly improves the efficiency of seat position adjustment in automotive verification models, accelerates comfort verification, and quickly verifies the impact of different seat positions on overall user comfort. It eliminates the need to separately manufacture or replace adjustment components for different seat position verifications, reducing costs incurred in verifying seat comfort during automotive development. It also saves verification time for different seat positions in automotive verification models, reducing the time required for early-stage automotive R&D and saving on R&D costs. The adjustment and positioning device of this invention enables precise adjustment and positioning of the seat support platform 6 and the seat on it in the X, Y, and Z directions, meeting the needs of simulating different seat positions in automotive verification models, improving testing accuracy and efficiency. Furthermore, the overall structure is stable and easy to operate, possessing high practicality and promotional value.

[0033] In a specific implementation, the present invention provides mounting holes on the seat support platform 6 for fixing the seat of the automobile verification model.

[0034] The present invention fixes the Z-axis lifting structure 2 below the lifting platform 1, which can provide stable support and lifting for the lifting platform 1. Two sets of Y-axis moving structures 4 are symmetrically distributed above the X-axis adjusting structure 3, which are subjected to balanced forces and do not shake during the movement, thus ensuring adjustment accuracy.

[0035] The Z-axis lifting structure 2 of the present invention includes a Z-axis drive motor 21, a Z-axis lead screw 22, a Z-axis slider 23, a scissor fork arm 25, and a Z-axis U-shaped plate 24. The output end of the Z-axis drive motor 21 is connected to the Z-axis lead screw 22. The Z-axis slider 23 is sleeved on the Z-axis lead screw 22. The bottom of the Z-axis U-shaped plate 24 is connected to the Z-axis slider 23. The two sides of the Z-axis U-shaped plate 24 are hinged to the lower end of the scissor fork arm 25. The scissor fork arm 25 is connected to the Z-axis slider 23 through the Z-axis U-shaped plate 24. The upper end of the scissor fork arm 25 is fixed to the bottom of the lifting platform 1. Z-axis drive motor 21 drives Z-axis lead screw 22 to rotate, thereby causing Z-axis slider 23 to move linearly. During the linear movement of Z-axis slider 23, it will drive Z-axis U-shaped plate 24 to move, which in turn drives the scissor fork arm 25 hinged to Z-axis U-shaped plate 24 to unfold or retract, realizing the overall movement of lifting platform 1 and its above Y-axis moving structure 4, two sets of X-axis adjusting structures 3, and seat support platform 6 along the Z-axis direction. The Z-axis lifting structure 2 of the present invention is equipped with scissor fork arm 25, which improves the stability of the lifting platform 1 during the lifting process, and the overall structural design is reasonable.

[0036] In a specific implementation of the present invention, the lifting platform 1 is made of Q235 steel plate. The upper end of the lifting platform 1 is provided with threaded holes for fixing the X-direction adjustment structure 3, and the four corners of the lower surface are provided with mounting holes for fixing the scissor fork arms 25 of the Z-direction lifting structure 2.

[0037] In this embodiment of the invention, the adjustment and positioning device includes a bottom support 7 and a Z-axis cable displacement sensor 8. The bottom end of the Z-axis lifting structure 2 is fixed to the bottom support 7, and the top end of the Z-axis lifting structure 2 is fixed to the lifting platform 1. The bottom end of the Z-axis cable displacement sensor 8 is fixed to the bottom support 7 and located on one side of the Z-axis lifting structure 2. The first cable terminal 81 of the Z-axis cable displacement sensor 8 is connected to the lifting platform 1. By setting the Z-axis cable displacement sensor 8, the Z-axis displacement of the lifting platform 1 can be monitored in real time, facilitating precise control of the seat's Z-axis position and improving verification accuracy.

[0038] In its specific implementation, the Z-axis draw-wire displacement sensor 8 includes a first draw-wire sensor 83, a first lead-out drum 86, and a first displacement measuring device 87. The first lead-out drum 86 is located at the upper end of the first draw-wire sensor 83 and is connected to it. The first displacement measuring device 87 is fixed to the middle of one side of the first draw-wire sensor 83. The first draw-wire sensor 83 is internally provided with a first self-winding spring 84 and a first reel 85. The first self-winding spring 84 is fixed inside the first draw-wire sensor 83 and is located on one side of the first reel 85. The first reel 85 is wound with a first draw-wire 82. 2. The end of the cable away from the first reel 85 passes through the first cable outlet 86 and extends outward to be fixed to the first pull terminal 81. A Z-direction connecting shaft 88 is provided in the middle of one side of the first pull sensor 83. The Z-direction connecting shaft 88 passes through the middle of the first self-coiling spring 84 and the middle of the first reel 85. The first self-coiling spring 84 is connected to the middle of the first reel 85 through the Z-direction connecting shaft 88. A Hall encoder 89 is fixed inside the first displacement measuring device 87. The first reel 85 is coaxially arranged with the Hall encoder 89 of the first displacement measuring device 87 through the Z-direction connecting shaft 88. In this invention, the linear motion of the first pull rope 82 is aligned with the motion axis of the lifting platform 1. During movement, the first pull rope 82 extends or retracts, driving the Z-direction connecting shaft 88 to rotate through the first reel 85. The Z-direction connecting shaft 88 outputs an electrical signal proportional to the movement distance of the first pull rope 82, which is converted by the Hall encoder 89 to obtain the displacement of the lifting platform 1.

[0039] The lower end of the scissor fork arm 25 of the Z-axis lifting structure 2 of the present invention is connected to the bottom support base 7, and the Z-axis drive motor 21 and the Z-axis lead screw 22 are both fixed on the bottom support base 7.

[0040] In a specific implementation, the present invention also fixes an anti-slip pad on the lower surface of the bottom support 7. The anti-slip pad is made of rubber material and has anti-slip texture on its lower surface. By setting an anti-slip pad on the bottom support 7, the present invention prevents the device from sliding during operation, improves the safety of use, and further enhances the practicality and promotional value of the device.

[0041] The X-axis adjustment structure 3 of the present invention includes an X-axis drive module 31, a connecting plate 32, an X-axis lead screw 33, an X-axis adjustment sliding seat 34, two sets of X-axis slide rails 35, and an X-axis slider 36 that cooperates with the two sets of X-axis slide rails 35. The X-axis drive module 31 is located at one end of the X-axis lead screw 33 and is connected to the X-axis lead screw 33. The X-axis adjustment sliding seat 34 is sleeved on the X-axis lead screw 33 and threadedly connected to the X-axis lead screw 33. Specifically, the outer circumferential surface of the X-axis lead screw 33 is provided with an external thread, and the middle part of the X-axis adjustment sliding seat 34 is provided with an internal thread hole that cooperates with the X-axis lead screw 33. When the X-axis lead screw 33 rotates around its own axis, the X-axis adjustment sliding seat 34 is threadedly connected to the external thread of the X-axis lead screw 33 through the internal thread, so that the X-axis adjustment sliding seat 34 moves linearly along the axial direction of the X-axis lead screw 33. The top of the X-axis adjusting sliding seat 34 is fixed to the bottom of the connecting plate 32, and the top of the connecting plate 32 is fixed to the Y-axis moving structure 4. Two sets of X-axis slide rails 35 are symmetrically fixed on the lifting platform 1.

The top of the X-axis slider 36 is also fixed to the connecting plate 32. The X-axis drive module 31 includes an X-axis drive motor 311 and an X-axis coupling 312. The output shaft of the X-axis drive motor 311 is connected to one end of the X-axis coupling 312, and the other end of the X-axis coupling 312 is connected to the X-axis lead screw 33. When the X-axis drive motor 311 drives the X-axis coupling 312 and the X-axis lead screw 33 to rotate, the X-axis adjusting sliding seat 34 will move along the axial direction of the X-axis lead screw 33, so that the connecting plate 32 at the upper end of the X-axis adjusting sliding seat 34 and the Y-axis moving structure 4 and the seat support platform 6 above the connecting plate 32 will slide on the X-axis slide rail 35, realizing the Y-axis moving structure 4 and the seat support platform 6 moving back and forth along the X-axis.

[0042] The X-direction adjustment structure 3 of the present invention includes a linkage slide plate 321, which is fixed to the upper end of the connecting plate 32 as an integral structure.

[0043] In this embodiment of the invention, the adjustment and positioning device includes an X-direction connecting seat 37 and a third pull-wire displacement sensor 9. One end of the X-direction connecting seat 37 is fixed to the linkage slide plate 321 of the X-direction adjustment structure 3. The third pull-wire displacement sensor 9 is fixed to the lifting platform 1.

The third pull-wire terminal 91 of the third pull-wire displacement sensor 9 is connected to the linkage slide plate 321 of the X-direction adjustment structure 3 through the X-direction connecting seat 37. In a specific implementation, the Y-direction drive structure 5 of the present invention includes a Y-direction drive motor 51 and a Y-direction coupling 52. The output shaft of the Y-direction drive motor 51 is connected to one end of the Y-direction coupling 52, and the other end of the Y-direction coupling 52 is connected to the Y-direction moving structure 4 for transmission. Each Y-axis moving structure 4 includes a Y-axis lead screw 41, a Y-axis sliding seat 42, a Y-axis slide rail 43, and a Y-axis slider 44 that cooperates with the Y-axis slide rail 43. The Y-axis coupling 52 of the Y-axis driving structure 5 is located at one end of the Y-axis lead screw 41 and is connected to the Y-axis lead screw 41 for transmission. The Y-axis sliding seat 42 is sleeved on the Y-axis lead screw 41 and is threadedly connected to the Y-axis lead screw 41. The upper end of the Y-axis sliding seat 42 is fixed to the middle of the bottom end of the seat support platform 6. Specifically, the outer circumferential surface of the Y-axis lead screw 41 is provided with an external thread, and the middle of the Y-axis sliding seat 42 is provided with an internal thread hole that cooperates with the Y-axis lead screw 41. When the Y-axis lead screw 41 rotates around its own axis, the Y-axis sliding seat 42 is threadedly connected to the external thread of the Y-axis lead screw 41 through the internal thread and moves linearly along the axial direction of the Y-axis lead screw 41. The Y-axis slide rail 43 is fixed to the upper end of the connecting plate 32 and located on one side of the Y-axis lead screw 41. The Y-axis slider 44 is slidably connected to the Y-axis slide rail 43 and can reciprocate along the extension direction of the Y-axis slide rail 43. The top of the Y-axis slider 44 is also fixed to the side of the bottom end of the seat support platform 6. When the Y-axis drive motor 51 drives the Y-axis coupling 52 and the Y-axis lead screw 41 to rotate, the Y-axis slide table and the seat support platform 6 above it move along the axial direction of the Y-axis lead screw 41. At the same time, the Y-axis slider 44 on the side of the bottom end of the seat support platform 6 slides along the Y-axis slide rail 43, realizing the reciprocating movement of the seat support platform 6 along the Y-axis. By setting the Y-axis slider 44 and the Y-axis slide rail 43, the stability of the seat support platform 6 moving along the Y-axis can be improved. This invention adopts two sets of Y-axis moving structures 4 symmetrically arranged, and drives the two sets of Y-axis moving structures 4 to move synchronously through the Y-axis drive structure 5, ensuring the symmetry and stability of the seat support platform 6 in the Y-axis direction adjustment.

[0044] In this embodiment of the invention, the adjustment and positioning device includes a Y-direction connecting seat 10 and a second pull-wire displacement sensor 11.

The second pull-wire terminal 111 of the second pull-wire displacement sensor 11 is connected to the linkage slide plate 321 of the Y-direction adjustment structure through the Y-direction connecting seat 10.

[0045] The working principle of this invention is as follows:

[0046] When it is necessary to adjust the Z-axis position of the car verification model seat, the Z-axis drive motor 21 is started. The Z-axis drive motor 21 drives the Z-axis lead screw 22 to rotate, causing the Z-axis slider 23 to move, which in turn drives the scissor fork arm 25 to unfold or retract, realizing the lifting platform 1 and the structure above it. At the same time, the Z-axis pull wire displacement sensor 8 monitors the lifting displacement of the lifting platform 1 in real time to ensure the accuracy of the lifting position measurement.

[0047] When it is necessary to adjust the X-direction position of the car verification model seat, the X-direction drive motor 311 of the X-direction adjustment structure 3 is activated. The X-direction drive motor 311 drives the X-direction lead screw 33 to rotate, causing the X-direction adjustment sliding seat 34 to move along the X-direction, thereby driving the two sets of Y-direction moving structures 4 and the seat support platform 6 to move along the X-axis.

[0048] When the Y-axis position of the seat needs to be adjusted, the Y-axis drive motor 51 of the Y-axis drive structure 5 is activated. The Y-axis drive motor 51 is driven through the Y-axis coupling 52 and the Y-axis lead screw 41, so that the Y-axis sliding seat 42 and the seat support platform 6 above it move axially along the Y-axis lead screw 41, so that the Y-axis sliders 44 at the bottom of both sides of the seat support platform 6 slide synchronously along the Y-axis slide rail 43, thereby improving the stability of the seat support platform 6 moving in the Y-axis direction.

[0049] By adjusting the three directions mentioned above, the position and location of the car verification model seat in three-dimensional space can be quickly adjusted to meet different comfort verification needs.

[0050] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of this application. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
