Description

Technical Field

[0001] The present invention belongs to the technical field of sightseeing vehicles, and in particular relates to an unmanned driving and intelligent guided sightseeing vehicle for use in scenic areas. Background Art

[0002] The driverless sightseeing car can realize functions such as autonomous route planning, autonomous driving, and autonomous obstacle avoidance by inputting the destination. It can be used for shuttle services in airports, parks, and other scenes without the need for a safety officer, helping the development of smart cities and providing tourists with efficient, safe, and comfortable autonomous driving travel services.

[0003] When multiple tourists ride on an unmanned sightseeing vehicle, due to differences in their weights, some of which can even differ by 100 pounds, and the fact that all tourists ride independently, the unmanned sightseeing vehicle is prone to unreasonable seating positions, causing left and right tilts, front and back tilts, making it prone to rollovers or tilting, greatly reducing driving safety. In addition, due to the different heights of tourists, when taller tourists sit in the front row and shorter tourists sit in the back row, the tourists in the back row cannot see the front, affecting the sightseeing effect.

[0004] Therefore, an unmanned driving and intelligent guided sightseeing vehicle for use in scenic spots is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1-7 The embodiment of the present invention proposes an unmanned driving and intelligent guided sightseeing vehicle for scenic spots, including a chassis 1 and a frame 2. Four running wheels 8 are symmetrically arranged at the bottom of the chassis 1. A control console 9 is provided on the inner bottom of the frame 2, close to one side end. The control console 9 is provided with a steering wheel and an interactive screen. The interactive screen can be used to view a 3D map of the scenic spot, AR real-scene navigation, and graphic introductions of the scenic spot. The interior of the control console 9 is provided with an on-board AI system, which automatically triggers voice guide content through GPS or high-precision map positioning, and explains the historical and cultural background of the scenic spot. The interior of the control console 9 is provided with an L4 fully automatic driving system, which can realize automatic path planning and obstacle avoidance.

[0032] A ball groove 31 in the frame tilt detection assembly 3 is provided at the top center of the chassis 1, and a rolling docking ball 32 is embedded in the inside of the ball groove 31. Four guide arc seats 33 and four pressure sensors 34 are symmetrically provided on the top of the chassis 1. The guide arc seat 33 is located on one side of the pressure sensor 34, and the guide arc seat 33 and the pressure sensor 34 are both located at the corners of the chassis 1. A ball protective cover 35 is provided at the bottom center of the chassis 1 near the outer side of the docking ball 32. A docking plate 36 is provided at the bottom center of the frame 2. The docking plate 36 is fixedly connected to the docking ball 32. The bottom of the frame 2 is close to the outer side of the four guide arc seats 33. A guide arc groove 37 is provided at each of the guide arc seats 33 and the guide arc groove 37. The cross-sections of the guide arc seat 33 and the guide arc groove 37 are both arc-shaped, and the centers of the guide arc seat 33 and the guide arc groove 37 are at the same point as the center of the docking sphere 32. Through the arc-shaped structure, the frame 2 fixed to the docking sphere 32 can be limited by the guide arc seat 33 during axial movement. The guide arc seat 33 and the guide arc groove 37 are used to guide the frame 2 so that a corner of the frame 2 applies pressure to the pressure sensor 34. The pressure applied is detected by the pressure sensor 34, and the tilt state of the frame 2 (the degree of left and right tilt and the degree of front and back tilt) is determined by the pressure difference detected by adjacent pressure sensors 34.

[0033] The four water tanks 41 in the frame balancing weight assembly 4 are symmetrically arranged at the bottom of the chassis 1. One-way water pumps 42 are fixedly connected to the outer walls of one side of the four water tanks 41 by bolts. The input end of the one-way water pump 42 is connected to the water tank 41, and the output end of the one-way water pump 42 is fixedly connected to a water pipe 43. The water pipe 43 is fixedly connected to the adjacent water tank 41, and one end of the water pipe 43 away from the one-way water pump 42 is fixedly connected and connected to the adjacent water tank 41. A ring-shaped circulation flow channel for water is formed between the four water tanks 41 under the connection of the one-way water pump 42 and the water pipe 43. The water circulates between the four water tanks 41 and the pumping capacity generated by the independent one-way water pump 42, and the water amount in the four water tanks 41 can be adjusted, and then the weight of the water tank 41 can be adjusted, so as to facilitate balancing the four corners of the chassis 1, thereby ensuring that the whole vehicle remains balanced and avoiding the problem of unbalanced pressure on both sides of the vehicle that is prone to rollover;

[0034] The bottom of the frame 2 is provided with a base 51 of the seat lifting assembly 5. An electric push rod 1 52 is embedded and fixed at the center of the top of the base 51. The electric push rod 1 52 is fixedly connected to the seat 53 through the output end on one side. Four limiting columns 54 are symmetrically provided at the bottom of the seat 53. Limiting holes 55 are provided at the top of the base 51 near the outer sides of the four limiting columns 54. Two electric push rods 2 56 are symmetrically provided inside the base 51. The two electric push rods 2 56 are fixedly connected to a guardrail 57 through the output end on one side. A part of the guardrail 57 is embedded in the interior of the base 51, and the guardrail 57 is a U-shaped structure. The guardrail 57 can protect tourists behind the seat 53 to prevent tourists from being thrown out when the sightseeing car brakes suddenly, and to reduce injuries caused by tourists colliding with the front seat 53.

[0035] A roof 6 is provided on the top of the frame 2. An infrared ranging sensor 7 is embedded through the top of the roof 6 near the position directly above the seat 53. The infrared ranging sensor 7 and the electric push rod 2 56 in the seat 53 in front of the seat 53 directly below form a control channel. When the infrared ranging sensor 7 detects the ranging signal, the on-board AI system in the console 9 controls the electric push rod 2 56 that cooperates with it to work. The electric push rod 2 56 drives the guardrail 57 to move upward through the output end on one side. After the guardrail 57 is lifted, it can protect the tourists behind the seat 53 directly below the infrared ranging sensor 7, avoiding the rear tourists from sitting in too high a position without protection.

[0036] The specific implementation method is as follows: the sightseeing car automatically drives according to the route set by the scenic area. After arriving at the parking point, the tourist gets on the car and chooses a seat 53 to sit down. When the tourist sits on the seat 53, the infrared ranging sensor 7 above the seat 53 measures the height of the tourist when sitting and transmits the ranging information to the control system in the sightseeing car. The control system controls and adjusts according to the height of the tourist sitting in front of the tourist. Specifically, the electric push rod 1 52 is controlled to drive the seat 53 to move upward through the output end on one side. Under the limit of the limit column 54 and the limit hole 55, the seat 53 rises steadily, and the tourist sitting on the seat 53 rises synchronously, so that the head of the tourist is higher than the head of the tourist in front, so that the tourists in the back row have a better viewing angle. At the same time, the control system also controls the guardrail 57 on the front seat 53 to rise synchronously, and the electric push rod 2 56 drives the guardrail 57 to move upward through the output end on one side. The guardrail 57 moves to the chest of the tourists in the back row, which can protect the tourists in the back row and prevent the tourists in the back row from sitting too high and lacking protection.

[0037] When all tourists have finished riding, due to the weight difference between the tourists, a relative tilt occurs between the frame 2 and the chassis 1. In order to avoid the uneven force on the sightseeing car and cause serious roll, the overall balance of the sightseeing car is adjusted. Specifically, the frame 2 deflects under the pressure generated by the weight of the tourists. The docking ball 32 rolls in the ball groove 31, and the guide arc seat 33 is inserted into the guide arc groove 37 to limit the deflection trajectory of the frame 2. The frame 2 deflects to one of the four corners of the chassis 1. At this time, the pressure sensor 34 on this corner detects the pressure value. The pressure values detected by the pressure sensors 34 are different. At this time, the control system controls the four one-way water pumps 42 to work. The one-way water pump 42 pumps the water in the water tank 41 connected to it into the adjacent water tank 41 through the water pipe 43. The pumping capacity generated by the independent one-way water pump 42 can adjust the water volume in the four water tanks 41, and then adjust the weight of the water tank 41, so as to facilitate the balancing of the four corners of the chassis 1, and ensure that the pressure values detected by the four pressure sensors 34 are not much different, thereby ensuring that the whole vehicle remains balanced and avoiding the problem of unbalanced pressure on both sides of the vehicle that may easily cause rollover.
