Description

Background Art

[0001] The present invention relates to an emergency system for driving and moving a vehicle in an emergency when the vehicle suffers a breakdown that prevents them from moving. The emergency system is a spare tire hidden under the vehicle interior, and the spare tire is operated by an electric motor to control a hydraulic arm, which controls the lowering and lifting of the spare tire when the vehicle needs to be moved.

[0002] One of the closest prior art cases is Saudi Patent Application No. 121420431, which describes a device installed at the back of the vehicle (not integrated with the vehicle as a whole) and including only two wheels. Thus, lifting the vehicle only lifts the rear wheels off the ground, rather than all four wheels as in the present invention. If the described invention were applied to the prior art, a vehicle with damaged front wheels would not be able to be moved by this device. In addition, the device described in the prior art operates relying on the vehicle's own battery, and in the case of a failure of the vehicle's motor or battery, this battery would not be able to supply energy to the device described in the prior art for a long time to move the vehicle an appropriate distance to reach a repair shop. Therefore, it is only suitable as a device independent of the vehicle in the case of a motor failure and the front wheels of the vehicle not being damaged. However, it is stored in the vehicle in a way that occupies a large space for use in an emergency, which is different from the device of the present invention that is integrally formed into the vehicle and stored in a hidden manner under the vehicle for use in an emergency, and the device of the present invention uses a special battery that can supply energy to it for a long time to operate.

[0003] One of the closest prior art cases described in U.S. Patent No. 9,758,133 is a vehicle emergency system that allows the vehicle to move and consists of small wheels lowered by a hydraulic arm. These small wheels are located behind each wheel of the vehicle and lift the vehicle and its wheels a short distance off the ground. These small wheels are only used to guide the vehicle right or left to assist in parking. It cannot move the vehicle forward and backward, and also cannot control the vehicle's steering in different directions. In the prior art, the joystick attached to the spare wheel only controls the vehicle's steering right or left and its speed. The wheels obtain energy from the vehicle. In the present invention, there is a special motor for the spare wheel, and the front wheels can be guided right and left. After lifting the entire vehicle on four spare wheels and traveling a distance determined by the life of the battery attached to the system, the special motor operates to move the entire vehicle, and the battery supplies the energy required for the electric motor of the additional wheels to operate. Different from what is described in the prior art, the present invention operates when the vehicle's main motor completely stops.

[0004] The prior art is described in Chinese Patent Document No. CN217074292U, which describes small wheels near the original wheels of a vehicle. In the event of a failure of the main wheels or when replacement is required, these small wheels are lowered individually, so that the small wheels lift the vehicle to enable the replacement of the original wheels. If the original wheels cannot be replaced, then additional wheels can be used and driven. The invention relies on the vehicle's motor to operate the additional wheels, and the additional wheels cannot be steered because each wheel is independent of the other and not connected to a steering wheel for steering, different from what is described in the present invention, in which there is a motor to move the additional wheels and steer two of the additional wheels to the right and left, using the additional wheels and the entire system as a vehicle that can be fully controlled and independent of the original vehicle. Summary of the Invention

[0005] The present invention aims to provide an emergency system for driving a vehicle when the vehicle suffers a failure, especially a failure that hinders the vehicle from moving from its position, such as an accident, fuel exhaustion, motor failure, battery failure, etc. The emergency system for moving the vehicle includes four wheels, two front wheels on the front axle and two rear wheels on the rear axle. Each axle is connected to a horizontal beam parallel to the axle and connected to the chassis via two hydraulic arms. The hydraulic arms operate to lower the spare wheels from their hidden positions below the vehicle to ground level, lifting the vehicle and its wheels off the ground, thereby allowing the spare wheels in the system to move the stalled vehicle. The spare wheels have electric motors connected to the rear or front wheels. The motors obtain their electrical energy from a battery, which obtains energy from the vehicle's main motor and stores the energy until it is needed. The battery can also be charged independently. The steering of the two front spare wheels is controlled via the vehicle's steering wheel, which is equipped with a spare steering column connected to the two spare wheels. The spare steering column is connected to the main steering column via a gear connecting the spare steering column and the main steering column. The vehicle is equipped with additional brake pedals and accelerator pedals above the original pedals of the vehicle hidden under the vehicle's trim, and they can be lowered via a system control panel located inside the vehicle's cab. These pedals operate together with the steering wheel to control the system described in the present invention to move the inoperable vehicle. Brief Description of the Drawings

[0014] The present invention is an emergency system for driving a vehicle when the vehicle suffers a failure that prevents the vehicle from moving, and the emergency system is fully shown in Figure 1 . The emergency system includes a spare wheel (1) powered by an electric motor (13), and the electric motor operates relying on a battery (12) to move the front or rear wheels (1). The wheel (1) and the motor (13) are hidden at the bottom of the vehicle and include two rear wheels (1) mounted at both ends of a horizontal column representing the rear axle (2) and two front wheels (1) mounted at both ends of a horizontal column representing the front axle (2). The hydraulic arms (3) are vertically mounted in the axle (2), and the hydraulic arms (3) connect a horizontal beam (4) mounted in the vehicle chassis and the axle (2) parallel to the horizontal beam, so as to move the spare wheel (1) out of their hidden positions in an emergency, and vice versa. Each axle (2) has at least two hydraulic arms (3). Each hydraulic arm (3) connects the axle (2) and a horizontal beam (4) parallel to the axle, and each horizontal beam (4) is connected to the vehicle chassis. By extending the hydraulic arms (3), the front and rear axles (2) together with the wheels (1) descend, and the wheels (1) work to lift the vehicle off the ground, thereby only allowing the vehicle to move through the spare wheels (1). By contracting the hydraulic arms (3), the front and rear axles (2) rise, and the original wheels of the vehicle return to the ground.

[0015] The operation of the system, the lowering of the hydraulic arm (3) and the spare wheel (1), and the selection of the forward or backward travel direction are controlled via a control panel (5) located in the cab, and the vehicle is accelerated, decelerated, and stopped via an acceleration and brake pedal bracket (6) mounted in a vertically movable bracket (6), and the bracket (6) is fixedly hidden in the trim panel under the steering wheel and is opened and lowered as needed in the event of an emergency and a failure that prevents the vehicle from moving. The vehicle is steered via a main steering wheel, the spare steering column (7) is connected to the main steering wheel, and the spare steering column is connected to a column (9) connecting the front spare wheel, and the connecting column (9) is connected to the main steering column via a gear (8). The commands for the components of the system issued by the control panel (5) and the acceleration and brake pedals (6) are organized via the controller (12) of the system. All components of the system are powered via their own battery (12), and data and commands are transmitted from the control panel (5) and the pedals (6) to the controller (10) via a data transmission harness (11).

[0016] The battery (12) is charged by the vehicle's circuit during normal operation of the vehicle. In the case where the emergency system in the present invention is activated and the main motor of the vehicle stops working and its circuit stops, the energy previously stored in the battery (12) is used to fully activate the emergency system. The battery (12) attached to the system can also be charged via an independent charging socket.
