[0002] In today's society, with the continuous improvement of people's quality of life, cultural and sports industries such as sightseeing and tourism have ushered in a golden period of rapid development. Travel and scenic area tours have become popular choices for modern people to relieve physical and mental stress and pursue spiritual happiness in their spare time, attracting a large number of tourists. With the continued prosperity of such natural scenic areas, the market demand for mountain sightseeing and mountaineering vehicles has also shown a growing trend. However, the routes these vehicles travel not only have steep climbing angles, but also have a constantly changing ascent and descent gradient. These driving conditions cause many problems for passengers, resulting in a sharp decline in the riding experience and a serious negative impact on sightseeing activities.

[0003] Specifically, when vehicles are traveling on these complex routes, passengers will lean back or forward significantly as the vehicle goes uphill or downhill. In most cases, passengers have to rely on their legs to support themselves to prevent themselves from sliding out of the seat. When the slope angle increases further, it may even cause the passenger to separate directly from the seat, posing a risk of injury. This poor riding experience not only makes passengers feel physically uncomfortable, but also distracts their attention and interest in appreciating the natural scenery outside, greatly affecting the pleasure and satisfaction of the trip. Therefore, how to develop a device that can automatically adjust the seat angle according to the slope of the vehicle, so as to effectively solve the problem of passengers' riding discomfort caused by slope changes on mountain sightseeing and mountaineering vehicles, and enhance the passengers' travel experience, has become a key technical problem that needs to be solved urgently.

[0044] Combine Figures 1-10 As shown, the present invention provides an adaptive angle-adjustable sightseeing chair, comprising a lower base 1, a sliding support 2, an upper platform 3, an adjustment guide 4, a drive 5, and a seat 7. Both the lower base 1 and the upper platform 3 are rectangular frame structures. The upper platform 3 is used to mount carriers such as seats and containers. It is provided with a platform mounting interface and a support surface that can be adjusted to suit different carriers. In this embodiment, the carriers are seats 7, which are arranged in a row. The lower base 1 serves as a support and positioning platform for securing various supporting components.

[0045] See Figures 1 to 3 as well as Figure 10 , sliding support seats 2 are symmetrically fixed on both sides of the upper end of the lower base 1. The upper platform 3 is located on the upper side of the lower base 1, and a seat 7 is fixed on the upper end of the upper platform 3, and adjustment guide members 4 corresponding to the sliding support seats 2 are symmetrically installed on both sides of the lower end of the upper platform 3. The adjustment guide member 4 slides on the sliding support seat 2, so that the upper platform 3 can swing relative to the lower base 1. The driving member 5 is arranged between the upper platform 3 and the lower base 1, one end of the driving member 5 is hinged to the lower base 1, and the other end of the driving member 5 is hinged to the upper platform 3; the driving member 5 is configured to drive the upper platform 3 to swing relative to the lower base 1 according to the inclination angle of the external compartment, so that the seat 7 always remains in a horizontal state.

[0046] This adjustment part innovatively adopts a cradle-type angle rotation structure, which intrudes less space into the car during the angle adjustment process. This design feature leaves more usable space inside the car, which is of great significance for the optimization of passenger riding space and improves the efficiency of car space utilization and riding comfort. The overall mechanism design is compact and the various components are reasonably arranged, which effectively reduces the space occupied; this makes the device more flexible for different types of mountain sightseeing and mountaineering vehicles, and will not cause a major impact on the original layout of the vehicle due to its large structure; the upper platform has good versatility and can match different types of carriers, such as seats, containers, etc.; whether it is to provide passengers with a stable and comfortable riding environment or to ensure the stability of goods during transportation, the device can play a role, greatly expanding its application scenarios and scope of application, and improving the practical value of the device.

[0047] In some embodiments, as Figure 4 、 Figure 5 and Figure 8 As shown, the upper end of the sliding support seat 2 is installed with a plurality of vertical support rollers 21 and transverse limiting guide wheels 22 at intervals along the arc direction, and the vertical support rollers 21 and transverse limiting guide wheels 22 are arranged alternately. An arc-shaped guide groove 401 is provided in the adjustment guide 4, and the vertical support rollers 21 and transverse limiting guide wheels 22 are rotatably installed in the arc-shaped guide groove 401. Among them, the vertical support roller 21 serves as the main load-bearing device, supporting the upper load while ensuring that the mechanism swings smoothly along the adjustment guide 4; the transverse limiting guide wheel 22 is used to offset the lateral force of the carrier (such as a seat), reduce the amount of mechanism shaking, and prevent problems such as jamming and wear caused by left and right inconsistency during movement. This structure, with the vertical support roller 21, the transverse limiting guide wheel 22 and the arc-shaped guide groove 401 working together, can ensure that the mechanism can move stably and smoothly.

[0048] In some embodiments, as Figures 4 to 8 As shown, the arc guide groove 401 includes a first arc groove 402 and a second arc groove 403 that are spaced apart and arranged opposite to each other; the two adjacent vertical support rollers 21 are oriented in opposite directions, with one vertical support roller 21 placed in the first arc groove 402 and the other vertical support roller 21 placed in the second arc groove 403; in this embodiment, there are three vertical support rollers 21. Considering that the inner side has a larger load-bearing capacity, two vertical support rollers 21 are arranged facing inward and the other vertical support roller 21 is arranged facing outward, which has a better load-bearing effect. The two adjacent lateral limiting guide wheels 22 are staggered, with one lateral limiting guide wheel 22 placed in the first arc groove 402 and the other lateral limiting guide wheel 22 placed in the second arc groove 403. This structure can reduce the difficulty of installation, facilitate the connection and assembly of the adjustment guide member 4 and the sliding support seat 2, and is conducive to ensuring the stable operation of the structure.

[0049] In some embodiments, as Figures 5 to 7 As shown, the adjustment guide member 4 includes symmetrical and spaced-apart sliding groove members 41 and a support plate 42 fixed between the two sliding groove members 41. One end of the sliding groove member 41 is arc-shaped, and the first arc-shaped groove 402 and the second arc-shaped groove 403 are respectively arranged in the two sliding groove members 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 groove members 41; both sides of the arc-shaped guide groove 401 are provided with an insertion entrance 404 for the vertical support roller 21 and the horizontal limiting guide wheel 22 to enter, and a decorative cover plate 44 for covering the insertion entrance 404 is fixed on one side or both sides of the adjustment guide member 4.

[0050] In some embodiments, as Figures 5 to 7 As shown, a limit member 43 is fixed in the middle of one side of the adjustment guide member 4, and limit baffles 201 corresponding to the limit member 43 are provided on both sides of the sliding support base 2. The limit baffles 201 are used to block the limit member 43, allowing the limit member 43 to swing between the two limit baffles 201. This structure, in which the limit member on one side of the adjustment guide member cooperates with the limit baffles on both sides of the sliding support base, mechanically limits the swing range of the upper platform, preventing damage caused by excessive swinging and ensuring safety in use.

[0051] In some embodiments, the device also includes a sensor installed on the external car body, and the sensor is electrically connected to the driver 5; the sensor is used to detect the tilt angle of the car body and output a signal to the driver 5, and the driver 5 drives the upper platform 3 to change the angle in real time to maintain a horizontal state. In this structure, a sensor is installed on the external car body, and the sensor is electrically connected to the driver through a circuit. This sensor has the function of accurately detecting the tilt angle of the car body, and can sense the angle changes of the car body during driving in real time, and output the tilt angle signal obtained by the detection to the driver. After receiving the signal, the driver accurately drives the upper platform to adjust the angle according to the preset control logic, thereby ensuring that the upper platform can change its own angle in real time and always maintain a horizontal state when the car body tilts due to changes in driving conditions.

[0052] In some embodiments, as Figure 3As shown, a safety sensor 6 is mounted on the sliding support 2, which is used to sense the two endpoints of the adjustment guide 4. In this structure, the safety sensor mounted on the sliding support can sense the two endpoints of the adjustment guide. When it detects that the adjustment guide is approaching its limit position, it can promptly issue a signal, enabling appropriate measures (such as emergency stop and alarm) to prevent a dangerous situation. A combination of mechanical limiters and safety sensors is deployed at the device's extreme positions. This dual safety mechanism maximizes the safety of the device during operation, providing strong protection for both passenger safety and the stability and reliability of the device itself.

[0053] In some embodiments, as Figure 8 and Figure 9 As shown, the upper end of the sliding support base 2 is provided with a plurality of raised portions 202 spaced apart, with a recessed portion 203 formed between two adjacent raised portions 202. The vertical support roller 21 is mounted on one side of the raised portion 202, and the transverse limiting guide wheel 22 is mounted in the recessed portion 203. This structure facilitates the arrangement of the vertical support roller 21 and the transverse limiting guide wheel 22, resulting in a reasonable and compact structural arrangement.

[0054] In some embodiments, as Figure 8 and Figure 9 As shown, the vertical support roller 21 is mounted on the sliding support base 2 via a first fastener 23. The vertical support roller 21 is mounted on one end of the first fastener 23, 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 is provided with a through hole for the first fastener 23 to pass through. A locking washer 25 is installed between the fastening nut 24 and the sliding support base 2, and the locking washer 25 is mounted on the first fastener 23. This structure facilitates the installation and adjustment of the vertical support roller 21, reducing installation difficulty.

[0055] The lateral limiting guide wheel 22 is connected to the sliding support base 2 via a second fastener 26. The sliding support base 2 is provided with a plurality of threaded holes 204 spaced along a straight line. The lateral limiting guide wheel 22 is mounted on one end of the second fastener 26, and the other end is threaded into the threaded hole 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 accommodating arcuate guide grooves 401 of varying sizes, thus reducing installation difficulty. To simplify the structure, the first fastener 23 and the second fastener 26 can be screws.

[0056] In some embodiments, as Figures 1 to 3As shown, the driving member 5 is a servo electric cylinder; a first articulated seat 51 is mounted on one end of the lower base 1, and a second articulated seat 52 is mounted on the end of the upper platform 3 facing away from the first articulated seat 51, with the first articulated seat 51 and the second articulated seat 52 both located in the middle. The telescopic end of the driving member 5 is hinged in the second articulated seat 52, and its other end is hinged in the first articulated seat 51. This structure, using a servo electric cylinder as the driving member, achieves precise control of the seat angle; the servo electric cylinder can accurately drive the upper platform to swing relative to the lower base based on the tilt angle signal detected by the sensor installed on the external car body, ensuring that the seat always remains in a horizontal state; this precise control can effectively improve passenger comfort and eliminate the discomfort caused by the tilt of the car body.

[0057] In some embodiments, as Figure 1 and Figure 2 As shown, the outer cover of the lower base 1 is provided with a cover shell 8, which can hide the driving member and the sliding support seat 2 inside the cover shell 8, making the appearance more beautiful; the cover shell 8 is provided with a groove body 801 for adjusting the movement of the guide member 4 and the driving member 5.

[0058] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the embodiments described later, the description is relatively simple, and the relevant parts can be referred to the partial description of the previous embodiments.
