[0045] In some embodiments, such as Figure 3 , Figure 4 and Figure 7 As shown, multiple vertical support rollers 21 and horizontal limiting guide rollers 22 are installed at intervals along the arc direction on the upper end of the sliding support base 2, with the vertical support rollers 21 and horizontal limiting guide rollers 22 arranged alternately. An arc-shaped guide groove 401 is provided inside the adjusting guide member 4, within which the vertical support rollers 21 and horizontal limiting guide rollers 22 are rotatably installed. The vertical support rollers 21 serve as the main load-bearing element, supporting the upper load while ensuring smooth swaying of the mechanism along the adjusting guide member 4; the horizontal limiting guide rollers 22 are used to counteract the lateral force of the carrier (such as a seat), reduce the amount of swaying of the mechanism, and prevent problems such as jamming and wear caused by inconsistent left and right movements during operation. This structure, with the vertical support rollers 21, horizontal limiting guide rollers 22, and arc-shaped guide groove 401 working together, ensures stable and smooth movement of the mechanism.

[0046] In some embodiments, such as Figures 4 to 7 As shown, the arc-shaped guide groove 401 includes a first arc-shaped groove 402 and a second arc-shaped groove 403 arranged at intervals and opposite to each other; two adjacent vertical support rollers 21 face opposite directions, with one vertical support roller 21 placed in the first arc-shaped groove 402 and the other vertical support roller 21 placed in the second arc-shaped groove 403; in this embodiment, there are three vertical support rollers 21. Considering the larger load-bearing capacity on the inner side, two vertical support rollers 21 are arranged facing inwards, and the other vertical support roller 21 is arranged facing outwards, which has a better load-bearing effect. Two adjacent lateral limiting guide wheels 22 are staggered, with one lateral limiting guide wheel 22 placed in the first arc-shaped groove 402 and the other lateral limiting guide wheel 22 placed in the second arc-shaped groove 403. This structure can reduce the installation difficulty, facilitate the connection and assembly of the adjustable guide 4 and the sliding support 2, and help ensure the stable operation of the structure.

[0047] In some embodiments, such as Figures 4 to 6 As shown, the adjusting guide 4 includes symmetrically arranged and spaced-apart sliding grooves 41 and a support plate 42 fixed between the two sliding grooves 41. One end of the sliding groove 41 is arc-shaped. The first arc-shaped groove 402 and the second arc-shaped groove 403 are respectively provided in the two sliding grooves 41. The upper platform 3 is fixed on the support plate 42. A receiving space for accommodating the sliding support seat 2 is formed between the two sliding grooves 41. The two sides of the arc-shaped guide groove 401 are provided with entry points 404 for the vertical support roller 21 and the horizontal limiting guide roller 22 to enter. A decorative cover plate 44 for covering the entry point 404 is fixed on one or both sides of the adjusting guide 4.

[0048] In some embodiments, such as Figures 4 to 6 As shown, a limiting member 43 is fixed at the middle position of one side of the adjusting guide member 4. Limiting baffles 201 corresponding to the limiting member 43 are protruding from both sides of the sliding support 2. The limiting baffles 201 are used to block the limiting member 43, allowing it to swing between the two limiting baffles 201. This structure, with the limiting member on one side of the adjusting guide member cooperating with the limiting baffles on both sides of the sliding support, mechanically limits the swing range of the upper platform, preventing excessive swing and damage, and ensuring safe use.

[0049] In some embodiments, the device further includes a sensor mounted on the outer carriage, electrically connected to the drive unit 5. The sensor detects the tilt angle of the carriage and outputs a signal to the drive unit 5, which in turn drives the upper platform 3 to change its angle in real time to maintain a horizontal state. In this structure, a sensor is installed on the outer carriage, and the sensor is electrically connected to the drive unit via a circuit. This sensor has the function of accurately detecting the tilt angle of the carriage, and can sense the angle change of the carriage during the driving process in real time, and output the detected tilt angle signal to the drive unit. After receiving the signal, the drive unit accurately drives the upper platform to adjust its angle according to preset control logic, thereby ensuring that the upper platform can change its angle in real time when the carriage tilts due to changes in driving conditions, and always maintain a horizontal state.

[0050] In some embodiments, such as Figure 1As shown, a safety sensor 6 is installed on the sliding support 2. The safety sensor 6 is used to sense the positions of the two end points of the adjusting guide 4. With this structure, the safety sensor installed on the sliding support can sense the positions of the two end points of the adjusting guide. When it detects that the adjusting guide is approaching its limit position, it can promptly issue a signal and take corresponding measures (such as emergency stop and alarm) to avoid dangerous situations. At the extreme positions of the device, a combination of mechanical limit switches and safety sensors is arranged as a safety protection measure. This dual safety protection mechanism maximizes the safety of the device during operation, providing strong protection for both passenger safety and the stability and reliability of the equipment itself.

[0051] In some embodiments, such as Figure 7 and Figure 8 As shown, the upper end of the sliding support 2 has multiple protrusions 202 spaced apart, and a recess 203 is formed between two adjacent protrusions 202; the vertical support roller 21 is installed on one side of the protrusion 202, and the lateral limiting guide roller 22 is installed at the recess 203. This structure facilitates the arrangement of the vertical support roller 21 and the lateral limiting guide roller 22, and the structure is reasonable and compact.

[0052] In some embodiments, such as Figure 7 and Figure 8 As shown, the vertical support roller 21 is mounted on the sliding support base 2 via a first fastener 23. One end of the first fastener 23 is fitted with the vertical support roller 21, and the other end passes through the sliding support base 2 and is threadedly connected to a fastening nut 24. The sliding support base 2 has a through hole for the first fastener 23 to pass through. An anti-loosening washer 25 is installed between the fastening nut 24 and the sliding support base 2, and the anti-loosening washer 25 is fitted onto the first fastener 23. This structure facilitates the installation and adjustment of the vertical support roller 21, reducing installation difficulty.

[0053] The lateral limiting guide wheel 22 is connected to the sliding support base 2 via a second fastener 26. The sliding support base 2 has multiple threaded holes 204 spaced along a straight line. One end of the second fastener 26 is fitted with the lateral limiting guide wheel 22, and the other end is threaded into one of the threaded holes 204. The second fastener 26 can be connected to different threaded holes 204 to adjust the position of the lateral limiting guide wheel 22, facilitating assembly and adapting to different sizes of arc-shaped guide grooves 401, thus reducing installation difficulty. To simplify the structure, the first fastener 23 and the second fastener 26 can be screws.

[0054] In some embodiments, such as Figure 1 and Figure 2As shown, the driving component 5 is a servo electric cylinder; a first hinge seat 51 is installed at one end of the lower base 1, and a second hinge seat 52 is installed at the end of the upper platform 3 opposite to the first hinge seat 51. Both the first hinge seat 51 and the second hinge seat 52 are located in the middle position. The telescopic end of the driving component 5 is hinged in the second hinge seat 52, and its other end is hinged in the first hinge seat 51. This structure, using a servo electric cylinder as the driving component, achieves precise control of the mechanism angle; the servo electric cylinder can precisely drive the upper platform to swing relative to the lower base according to the tilt angle signal detected by the sensor installed on the external carriage, ensuring that the upper platform always remains in a horizontal state; this precise control can not only effectively improve the passenger's riding comfort and eliminate the discomfort caused by the tilt of the carriage, but also better protect the items placed in the carriage and prevent items from slipping or being damaged due to the tilt of the platform.
