Description

Technical Field

[0001] This invention relates to the field of vehicle safety auxiliary device technology, specifically to a multi-functional tracked anti-skid and traction device for automobiles. Background Technology

[0002] Vehicle extrication refers to the process by which a vehicle regains its ability to drive autonomously when it is unable to move normally due to insufficient friction between its tires and the ground, such as being buried in snow, stuck in mud, or encountering terrain obstacles. Traditional extrication methods rely on external rescue or simple tools such as snow chains, which have limitations such as delayed response, cumbersome operation, and limited functionality.

[0003] The following technical problems exist in the existing technology:

[0004] Functional defects:

[0005] Tools such as snow chains only temporarily increase friction and cannot cope with deep vehicle entrapment or complex terrain, and do not have active driving capabilities;

[0006] Systemic deficiencies:

[0007] The vehicle itself lacks an integrated structure, making it difficult to simultaneously achieve complex functions such as anti-slip, lifting, and maneuver control.

[0008] This design aims to directly address the technical problems of insufficient active anti-skid, rapid extrication, and multi-dimensional mobility of vehicles under extreme road conditions through a chassis-integrated track mechanism. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this invention provides a multi-functional tracked anti-skid and traction device for automobiles, which solves the technical problems mentioned in the background section.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional tracked anti-skid and traction-avoidance device for automobiles, installed on an automobile chassis, comprising:

[0011] Tires, electric hydraulic cylinders, and four independently controlled drive tracks;

[0012] The two sets of drive tracks are arranged laterally at the front and rear edges of the vehicle chassis, forming a transverse track assembly.

[0013] The other two sets of drive tracks are arranged longitudinally between the front and rear tires on the left and right sides of the vehicle chassis, forming a longitudinal track assembly;

[0014] The electric hydraulic cylinder is connected to and drives the drive track to perform lifting and horizontal extension / retraction movements;

[0015] The transverse track assembly achieves vertical lifting and lowering of the vehicle body via an electric hydraulic cylinder;

[0016] The longitudinal track assembly is extended horizontally to a position parallel to the tire or more than 10cm above the tire's ground contact height via an electro-hydraulic cylinder.

[0017] Preferably, the lifting stroke of the transverse track assembly is 50–100 cm, used to lift the vehicle body off the flooded road surface or reduce the impact of water flow.

[0018] Preferably, the longitudinal track assembly is driven by an electro-hydraulic cylinder and can independently adjust its extension height and horizontal position, enabling it to replace tires for load-bearing travel in muddy, snowy, or swampy conditions.

[0019] Preferably, the electro-hydraulic cylinder is connected to the transmission mechanism of all driving tracks to control track lifting, lateral translation and longitudinal movement.

[0020] Preferably, it also includes a programmable PLC control system for manually or automatically controlling the drive track to achieve the following functions:

[0021] vehicle body lifting

[0022] Longitudinal track assembly horizontal extension / retraction

[0023] Four sets of drive tracks work together to achieve 360° turning on the spot.

[0024] Four sets of drive tracks move synchronously laterally to enable the vehicle to traverse sideways.

[0025] Precisely control vehicles to enter parking spaces or pass over simple roadblocks.

[0026] Preferably, the lateral track assembly, in conjunction with the longitudinal track assembly via differential drive, enables the vehicle to perform on-the-spot turning and lateral movement in narrow spaces.

[0027] Preferably, when the vehicle gets stuck in snow or mud, the longitudinal track assembly extends to a position 10cm above the tire ground contact height to provide continuous driving force for getting out of trouble.

[0028] Preferably, the size, motor power, and load capacity of the drive track are customized according to the vehicle's load capacity, and the drive track is a transmission assembly consisting of track plates, gears, pulleys, and hardware accessories.

[0029] Preferably, the drive track assembly adopts a modular design and is quickly folded and fitted to the underside of the vehicle chassis via an electric hydraulic cylinder.

[0030] Preferably, the device integrates anti-slip, anti-sinking, vehicle body lifting, on-the-spot turning, lateral movement, precise parking, and self-rescue functions.

[0031] Beneficial effects

[0032] This invention provides a multi-functional tracked anti-skid and get-out-of-trouble device for automobiles. The invention significantly improves the safety and maneuverability of vehicles in complex road conditions by having four sets of drive tracks (4) integrated into the vehicle chassis (1) and working in coordination with an electric hydraulic cylinder (3). Its core value lies in: firstly, by extending the longitudinal track assembly below or beyond the tire's contact patch height, it directly enhances the vehicle's adhesion and passability on icy and muddy roads, effectively suppressing the risk of skidding and getting stuck; secondly, by utilizing the transverse track assembly to lift the vehicle body, it avoids water erosion of key components and reduces water flow impact; and thirdly, by using the independent control of the four tracks, it endows the vehicle with flexible maneuverability functions such as on-the-spot turning and lateral movement, assisting in precise parking in narrow spaces and obstacle avoidance. The overall structure is based on a customized design for the vehicle model, providing the driver with an active and multi-functional means of ensuring driving safety without altering the original vehicle architecture.

[0060] Track assembly layout Lateral track assemblies (2 sets): It is fixed to the front and rear edges of the car chassis (1) and vertically connected to the chassis via an electric hydraulic cylinder (3).

[0061] Function: To lift the vehicle body (travel 50–100 cm), and to lift the tires (2) off the ground when lifting.

[0062] Application scenarios: For flooded roads: Raise the vehicle body 80cm to prevent water from entering the engine and causing it to stall; Flooded sections: Raise the vehicle by 60cm to reduce the impact of water flow on the vehicle body.

[0063] Longitudinal track assemblies (2 sets): Installed on the left and right sides of the chassis (1), located between the front and rear tires (2). The horizontal telescopic boom is controlled by an electric hydraulic cylinder (3) to achieve: Stretching position: Parallel to tire (2); The tire (2) is more than 10cm above the ground contact height.

[0064] Function: To replace tires for load-bearing driving on snowy / muddy roads.

[0065] Note: All drive tracks (4) consist of track plates, drive gears, guide pulleys, motors and hardware accessories. The size is customized according to the vehicle's load capacity (15cm for small vehicles and 30cm for large vehicles).

[0066] Core Function Implementation Process (1) Anti-slip and get-out-of-trouble mode (taking snow as an example) Step 1: The driver triggers the "Get Out of Trouble" command on the PLC control panel; Step 2: The electric hydraulic cylinder (3) of the longitudinal track assembly pushes the track to extend horizontally until it exceeds the ground contact height of the tire (2) by 10cm; Step 3: Drive the track (4) motor to start, the track plates grip the ground to provide driving force, and the vehicle moves smoothly in the snow.

[0067] (2) Vehicle body lifting and wading driving Step 1: The PLC system receives the water depth sensor signal (water depth > 40cm); Step 2: The electric hydraulic cylinder (3) of the transverse track assembly is lifted synchronously to raise the vehicle body by 70cm; Step 3: Extend the longitudinal track assembly to the ground and move it away from the waterlogged area at a speed of 5 km / h.

[0068] (3) 360° turn and lateral movement in place Step 1: Activate "Steering Mode" and PLC controls the four sets of drive tracks (4) to run at different speeds; Left track moves forward + right track moves backward → achieves rotation in place; Step 2: Activate "lateral movement mode", the four tracks drive laterally in sync → the vehicle moves laterally across obstacles.

[0069] (4) Precise parking and self-rescue Scenario 1 (Narrow parking space): The longitudinal track assembly has its extension angle finely adjusted, and the PLC, combined with camera data, controls the lateral creeping movement of the track into position.

[0092] Scene 2 (Car stuck in mud):

[0093] The transverse track assembly lifts the vehicle body by 50cm → the longitudinal track assembly extends to the edge of the mud pit to compact the ground → the track drive tows the vehicle body out of the predicament.
