Description

TECHNICAL FIELD

[0001] The present application relates to VR simulation technology, in particular to a vehicle simulation simulation chassis. BACKGROUND

[0002] Driving simulator is a kind of teaching equipment for driving training. It uses virtual reality simulation technology to create a virtual driving training environment, and people interact with the virtual environment through the operation components of the simulator to conduct driving training. The driving simulator in a broad sense includes car driving simulator, aircraft driving simulator, ship driving simulator, etc. The vehicle simulation simulation chassis is applied to the bottom structure of the simulation simulator.

[0003] The vehicle simulation simulator in the prior art has the following shortcomings:

[0004] 1. High center of gravity: In order to make up for the lack of movement freedom of the 4-axis 3-degree-of-freedom G-force vehicle simulator, the front and rear movement and the left and right deviation are installed as two independent movement mechanisms on the original equipment.

[0005] 2. Difficulty in installation: It needs to be modified and processed on the original equipment to realize it. ①The front and rear movement mechanism (including a longitudinal installation of a telescopic cylinder) is installed under the seat of the original equipment. ②The left and right deviation movement mechanism needs to be connected with the original equipment through special connecting parts to transmit power. The difficulty coefficient is large, and the user is not easy to complete the upgrade of the original equipment.

[0006] 3. Low safety factor: ①The front and rear movement and the left and right deviation are installed as two independent movement mechanisms on the original equipment, which increases the overall height of the equipment, making the user's steps of getting on and off the equipment complicated, and the equipment is prone to rollover when moving violently due to high center of gravity. ②The front and rear movement mechanism uses V-shaped guide rail, which is prone to derailment when used intensively or combined with the original equipment.

[0007] 4. Low durability and short service life: ①The front and rear movement mechanism uses V-shaped guide rail which is directly exposed to the outside and is prone to damage, rust, and jamming. ②Two telescopic cylinders are directly installed horizontally at the bottom. The space utilization is poor, and they are directly exposed to the outside. If they are used for a long time, the internal telescopic cylinder is prone to eccentric wear under the action of gravity, pressure, and movement load, and the gap becomes larger, causing the equipment to run in danger. SUMMARY

[0008] In order to overcome the above technical defects, the present application provides a vehicle simulation simulation chassis.

[0024] 7.
