Description

Technical Field

[0001] This utility model relates to the field of sightseeing vehicle chassis technology, specifically a shock-absorbing and lifting chassis for intelligent sightseeing vehicles. Background Technology

[0002] With the booming development of the tourism industry and the widespread application of intelligent technology, intelligent sightseeing vehicles have become an important means of transportation in scenic spots, theme parks and other places due to their advantages such as automated operation and convenient tours. In actual operation, intelligent sightseeing vehicles often need to deal with complex and diverse road conditions, such as bumpy mountain roads and uneven cobblestone roads. This places stringent requirements on the shock absorption performance of the vehicle chassis. The shock absorption system of traditional sightseeing vehicle chassis mostly uses springs or hydraulic shock absorbers with fixed parameters, which makes it difficult to dynamically adjust the shock absorption effect according to different road conditions and the number of passengers. This results in poor comfort during vehicle operation and may affect the stability and accuracy of the intelligent control system.

[0003] Meanwhile, in order to meet the boarding and alighting needs of different tourists, especially those with mobility impairments, and to adapt to the height of different connecting platforms, it is crucial that the chassis has a lifting function. However, existing sightseeing vehicle chassis lack an efficient integrated shock absorption and lifting solution, and have problems such as complex structure, inconvenient operation, and slow response speed. They cannot take into account the comfort, safety and convenience of vehicle driving. Therefore, we propose a shock absorption and lifting chassis for intelligent sightseeing vehicles.

[0044] Adjustable reinforcing plate 10: It has a connecting hole 16 on the side and is slidably connected to the support beam 2 through the guide slide rod 9.

[0045] Buffer spring 11: One end is fixed to the bottom surface of the adjusting reinforcing plate 10, and the other end is fixed to the wheel support platform 4. It absorbs the impact force of the road surface through elastic deformation.

[0046] Shock-absorbing damping slide bar 12: One end is fixed to the top surface of the wheel support platform 4, and the other end extends into the shock-absorbing damping sleeve 13 to slide, and consumes vibration energy through hydraulic damping.

[0047] The damping sleeve 13 is fixed to the bottom surface of the adjusting reinforcing plate 10 and is slidably connected to the damping slide rod 12 on the inner side. The internal hydraulic oil generates damping force through the damping hole.

[0049] Communicating hole 16: It is opened on the side of the adjusting reinforcing plate 10 and is concentrically aligned with the adjusting threaded groove 8, for the fixing bolt 15 to pass through and connect to the supporting beam 2;

[0050] Working principle: When this utility model is needed, the lifting hydraulic cylinder 6 is fixed in the mounting groove on the bottom surface of the sightseeing vehicle chassis 1. The driving hydraulic rod 7 is fixedly connected to the supporting crossbeam 2. When the hydraulic system injects or discharges hydraulic oil into the lifting hydraulic cylinder 6, the driving hydraulic rod 7 extends and retracts axially, causing the supporting crossbeam 2 to move up and down, thereby adjusting the overall height of the chassis. The lifting protection spring 5 is sleeved on the outside of the driving hydraulic rod 7. Under normal working conditions, it elastically deforms with the extension and retraction of the hydraulic rod. If the hydraulic system fails, the spring can provide mechanical support force to prevent the chassis from suddenly falling, ensuring the safety of the vehicle and passengers. At the same time, the reinforcing plate 10 is guided by the guide slide rod 9. The adjusting reinforcing plate 10 is slidably connected to the supporting beam 2, with its side connecting hole 16 concentrically aligned with the adjusting threaded groove 8 of the supporting beam 2. After loosening the fixing bolt 15, the adjusting reinforcing plate 10 can slide up and down along the guide slide rod 9 to change its installation position on the supporting beam 2. After adjustment, the fixing bolt 15 passes through the connecting hole 16 and screws into the adjusting threaded groove 8 to fix the adjusting reinforcing plate 10. This position determines the initial compression of the buffer spring 11 and the stroke of the shock-absorbing damping slide rod 12, thus adapting to different loads or road conditions. When the wheel 3 encounters bumps while driving, the wheel support platform 4 moves upward along the guide slide rod 9, compressing the buffer spring 11. The elastic deformation of the spring absorbs part of the impact force, reducing the vibration transmitted to the vehicle body. Simultaneously, the damping slide rod 12 slides upwards within the damping sleeve 13. Hydraulic oil within the sleeve generates damping force through the damping hole, converting kinetic energy into heat energy, further attenuating the vibration amplitude and preventing secondary impacts when the spring rebounds. The guide slide rod 9 passes through the wheel support platform 4 and the adjusting reinforcing plate 10, providing rigid guidance for the vertical movement of the wheel support platform 4, ensuring accurate trajectory of the wheel 3 during shock absorption and preventing lateral deviation from affecting vehicle stability. When the sightseeing vehicle travels on bumpy roads, the wheel 3 is impacted, and the damping components immediately... Upon startup, the buffer spring 11 and the shock-absorbing damping slide rod 12 work together to quickly absorb and dissipate vibration energy. If the road conditions require the chassis to be raised to pass obstacles, the lifting hydraulic cylinder 6 operates synchronously to raise the chassis height. Through the cooperation of the guide slide rod 9 and the support beam 2, the lifting process is ensured to be smooth. By adjusting the position of the reinforcing plate 10, the "soft / hard" mode of the shock absorption component can be preset. Under heavy load or bumpy road conditions, the reinforcing plate 10 is lowered to increase the compression and damping stroke of the buffer spring 11, thereby enhancing the shock absorption effect. Under light load or flat road conditions, the reinforcing plate 10 is raised to reduce the spring preload and improve driving flexibility.
