Autonomous Vehicle Jack

Abstract

This invention relates to an automated jacking system that safely and stably lifts a vehicle without the need for human intervention in situations such as tire changes, flat tires, or underbody maintenance. The system can be integrated into the vehicle body or designed as a robotic unit operating independently of the vehicle. Technical Problems It Solves: Physical Difficulty and Safety: Eliminates the need for the user to exert physical strength and reduces the risk of injury that may occur while lifting the vehicle. Incorrect Positioning: Prevents vehicle damage that could result from placing the jack in the wrong locations on the chassis. Challenging Conditions: Solves the difficulty of setting up a jack in the dark of night, in rainy / muddy weather, or on sloping ground. Key Features: Automatic Detection and Alignment: Using its sensors (camera, proximity sensors, or LiDAR), the vehicle automatically detects safe lifting points (jack pockets) on the chassis and aligns with millimeter precision. Intelligent Integration: The vehicle can be operated directly via its own on-board computer system (OBD), tire pressure sensors, or a command from a mobile application. In the event of a tire blowout, the vehicle can automatically pull itself to a safe location and deploy the jack. Safe Stability Control: Thanks to pressure sensors located on its undercarriage, it measures the softness and slope of the ground. It stops operation and warns the user on unsafe surfaces (e.g., muddy or excessively steep). Automatic Mechanical Lock: When the vehicle reaches the target height, a mechanical safety lock automatically engages, preventing the vehicle from falling even if the electrical or hydraulic pressure is interrupted.

INVENTION NAME: AUTONOMOUS VEHICLE JACK SYSTEM AND METHOD 1. Technical Field to Which the Invention Relates This invention relates to the automotive industry and vehicle maintenance equipment. The invention specifically applies to vehicles. Wheel changes, underbody maintenance, or emergencies can be performed without requiring human intervention. Autonomous systems that safely lift the vehicle by analyzing environmental conditions and the vehicle chassis. It relates to an (automatic) jacking system and how this system works. 2. Prior State of the Invention (Prior State of the Art) Today, mechanical, hydraulic, or other methods are used for wheel changes or underbody repairs on vehicles. Electric jacks are used. However, current systems present serious usage difficulties and It involves security risks:  Physical Strength Requirement: Installing standard jacks and lifting the vehicle. This requires significant physical exertion. This situation is particularly relevant for the elderly, disabled, or those with insufficient physical strength. This can make the process impossible for individuals.  Incorrect Alignment and Chassis Damage: The jack should not be positioned at the correct lifting points under the vehicle. Failure to align perfectly (with the jack pockets) can cause the vehicle to slide, fall, or This causes the chassis to bend and become damaged.  Ground Insecurity: Using a jack on sloping, wet, muddy, or loose ground. This is quite dangerous. The current jacks cannot perform ground analysis, therefore there is a risk of tipping over. It invites accidents.  Challenging Weather and Environmental Conditions: Driving the vehicle in the dark of night or during stormy weather. Trying to remove it would be both a waste of time and a risk to life safety. It opens. 3. Solutions and Objectives Presented by the Invention The main purpose of the invention is to eliminate the disadvantages mentioned above by providing a safe, fast and The goal is to provide a completely user-independent (autonomous) vehicle lifting experience. 35 Other purposes of the invention are as follows:  To reduce the user's need for physical strength to zero.  By measuring the slope and hardness of the ground with the help of sensors, it can identify unsafe ground conditions. Preventing 40 studies.  Autonomously detects the correct lifting points on the vehicle's chassis with millimeter precision. To align.  A mechanical system that prevents the vehicle from falling in the event of an electrical or hydraulic failure. to provide a safety lock. 45  By integrating with the on-board computer system (OBD) and mobile applications, it provides users with To provide a user-friendly control interface. 50 4.

Detailed Description of the Invention The autonomous vehicle jack system that is the subject of the invention basically consists of a main body (1), this body a telescopic lifting arm (2) that moves vertically on it, moves the system It consists of driving wheels (6) and a control unit (5) that manages the entire system. The system is designed as a standalone robotic unit. Pressure loss in vehicle tires. when this happens or when the user gives the "Remove" command from the mobile application / in-car screen The system becomes active. 70 How the System Works and Steps: 1. Alignment and Positioning: The environmental and chassis sensing unit (4) is located under the vehicle. It scans the safe lifting points determined by the manufacturer. The control unit (5) scans these By processing the 75 data, it directs the drive wheels (6) and the jack under the chassis to the correct position. It ensures that it is placed precisely at the point. 2. Ground Analysis: Before the lifting operation begins, the ground located under the main body (1) The ground analysis sensor (3) measures the slope and bearing capacity (hardness) of the ground. If if the ground slope exceeds the specified limit value or if the ground is too soft (for example 80 mud), the control unit (5) stops the operation and the wireless communication module (9) It sends a warning to the user via this method. 3. Lifting Operation: When the ground is found to be safe, the power supply and motor unit (8) are activated. By becoming a telescopic lifting arm (2), it moves upwards. Lifting Pressure sensors at the top of the arm detect the moment of contact with the chassis and the lifting speed. 85 is adjusted in a controlled manner after this stage. 4. Safety Lockout: When the vehicle reaches the desired height, the telescopic lift is locked in place. The mechanical safety lock (7) located on the arm (2) is physically engaged. This ensures that even if there is a hydraulic or electrical power loss, the vehicle cannot suddenly descend. This prevents it from falling. 90 5. Download Process: When the process is complete, the mechanical safety lock (7) control unit (5) is pulled back and the lifting lever (2) slowly returns to the starting position. He lowers the vehicle to the ground. 2 6. How the Invention Can Be Applied to Industry 95 This invention is suitable for use in the automotive parts industry, vehicle maintenance stations, and roadside assistance equipment. in production and directly as standard luggage equipment in autonomous vehicles in mass production It is suitable. The developed software, sensor technologies and mechanical structures are compatible with existing industrial systems. It can be easily manufactured on production lines. 3
