Description

A wheel-driven anti-slip and anti-sinking device that is easy to install and remove, and its execution program. Technical Field

[0001] This invention belongs to the field of wheeled drive, specifically relating to a wheeled drive anti-slip and anti-sinking device that is easy to install and remove, and its execution program. Background Technology

[0002] Wheel drive is widely used in various fields in today's society, mainly in the form of various transportation vehicles. From ordinary road traffic to cutting-edge scientific exploration of Mars and the Moon, wheel drive vehicles are present everywhere. They are also found in harsh environments such as polar regions, Gobi Desert, rainforests, and more, greatly expanding the scope of human activity. However, even vehicles known for their off-road capabilities still encounter problems in harsh outdoor environments, such as losing traction, getting stuck on soft ground, or having their tires damaged by gravel, leading to people and vehicles becoming trapped, increasing exposure time in the wild, and increasing danger. Furthermore, while current wheel drive vehicles prioritize on-road comfort and fuel economy, they struggle to maintain suitability for harsh environments. When faced with freezing rain or snow causing low traction, vehicles cannot drive normally, experiencing tire slippage, increased braking distance, or lateral movement, which can easily lead to traffic accidents. These problems limit the multi-environment, multi-scenario usability of these vehicles. Technical issues

[0003] For wheeled vehicles that lose traction and become stuck on soft ground during off-road driving, current solutions involve adding winches or traction ramps. However, this is a reactive approach, failing to anticipate problems and lacking flexibility. Furthermore, this method of rescuing after being stuck is time-consuming and physically demanding. Existing devices cannot simultaneously address both slippage and traction issues, lacking versatility and failing to meet the needs of various scenarios. There are currently no specific solutions for environments like gravel roads that can damage tires. Regarding the issue of low traction in freezing rain and snow, solutions should address both increasing friction and contact area. Current solutions only increase friction by altering the contact surface, without combining both approaches. Additionally, existing solutions and products are cumbersome to operate and time-consuming. Some require operators with certain manual dexterity, while others demand physical strength, making them particularly unsuitable for women. Technical solutions

[0004] The invention includes a convenient-to-install wheel-driven anti-slip and anti-sinking device, comprising a central mechanical body, a flexible body connected to the central mechanical body, a tightening rope that passes through the entire flexible body and enters the central mechanical body, and an execution program.

[0005] The central mechanical body includes a winding wheel, a torque limiter, a coaxial gear of the winding wheel, a pawl, a pawl lever mechanism, and a central gear.

[0006] The torque limiter is located between the winding wheel and the coaxial gear of the winding wheel, and the coaxial gear of the winding wheel drives the winding wheel to rotate through the torque limiter.

[0007] The flexible body has protrusions, which increase the contact area between the flexible body and the ground.

[0008] The flexible body has multiple blades, which are divided into two types: flexible blades with multiple through holes and flexible blades with a single through hole. The difference between these two types lies in the presence of different through holes on the flexible blades. The flexible blade with multiple through holes is characterized by: one end being connected to the mechanical body, with two through hole openings at this end, each of which is connected to two through hole openings at the other end; the other end, in addition to the through hole openings connected to the mechanical end, also has one or more through holes, with the two openings of the through holes located on opposite sides with smaller cross-sectional dimensions, through which the tightening rope passes. The flexible blade with a single through hole is characterized by: one end being connected to the mechanical body, and the other end having a through hole, with one or more of these through holes at this end; the two openings of these through holes located on opposite sides with smaller cross-sectional dimensions, through which the tightening rope passes.

[0009] The tightening rope can be one or more, and each tightening rope can connect all the flexible bodies in series. The tightening and releasing of the tightening rope is controlled by a central mechanical body. The two ends of the same tightening rope can be connected and fixed to two winding wheels respectively. Alternatively, one end of the same tightening rope can pass through a defined flexible body fan blade with multiple through holes and enter the central mechanical body to connect with the winding wheel, while the other end is fixed to the defined flexible body fan blade with multiple through holes. When the tightening action is performed, the tightening rope is wound around the winding wheel. When the tightening rope performs the tightening action, it drives the flexible body, causing the flexible body to adhere tightly to the tire sidewall.

[0010] The procedure for the easily installable and removable wheel-driven anti-slip and anti-sinking device is as follows: After the device is fitted onto the tire, the first tightening action is performed. This can be done manually by using a hand crank with a matching connector or a hand drill to power the central gear. The central gear drives the coaxial gear of the winding wheel to rotate. The coaxial gear, through a torque limiter, drives the winding wheel to rotate. At this time, the tightening rope is wound around the winding wheel. When the tightening rope is taut and the winding wheel can no longer rotate, the torque limiter cuts off the torque transmission. The winding wheel cannot rotate with the coaxial gear of the winding wheel. The pawl engages with the ratchet of the winding wheel to prevent the winding wheel from rotating in the opposite direction, stopping the power transmission and completing the first tightening action. At this point, the tire's contact area with the ground prevents the tightening rope from reaching the ground. The tire sidewall on one side of the vehicle body also prevents the flexible body in that area from adhering tightly to the tire. As the tire rotates forward or backward, the contact area between the tire and the ground changes. The obstructed tightening rope goes around the contact area between the tire and the ground and performs a second tightening action. The second tightening action is the same as the first tightening action. When the second tightening action is completed, the tightening rope tightens, and the obstructed flexible body adheres tightly to the tire like other flexible bodies. At this point, the second tightening is completed. To ensure the reliability of the anti-skid and anti-sinking device that is quickly installed on the tire and to release the stress between the anti-skid and anti-sinking device and the tire, the wheel drive equipment with the device installed can be driven a sufficient distance before performing a third or more tightening actions to ensure that the flexible body adheres tightly to the tire. Beneficial effects

[0011] Compared to similar products with limited functionality and restricted operating environments, this invention increases the contact area between wheeled vehicles and the ground, providing both anti-skid and anti-sinking functions. In terms of operating environment, it can be used on unpaved roads such as sand, mud, and gravel, as well as on roads covered with snow and freezing rain in winter, playing a role in a variety of scenarios.

[0012] In harsh outdoor environments where there is a risk of getting stuck, other product solutions only provide rescue after the vehicle has gotten stuck, without taking preventative measures in advance. Compared to other products, this invention can be used for rescue and can also be installed in advance to avoid getting stuck, while also providing some protection for the tires.

[0013] When off-road vehicles need to traverse different environments such as paved roads and unpaved surfaces, it is inconvenient to change tires. They can only sacrifice comfort and fuel economy by choosing off-road tires. The advantage of this invention is that the vehicle can use ordinary tires on paved roads, while the vehicle can be fitted with the tires of this invention on unpaved roads, thus solving this problem.

[0014] This invention offers ease of operation while ensuring reliability and safety: the inner fastening operation is moved from the relatively narrow space between the wheel and the vehicle body to the side of the wheel that is relatively far from the vehicle body, making the operation simple and convenient; by adding a hand drill with a matching socket as a power source, physical effort is saved and convenience is improved.

[0025] Exemplary embodiments will be described in detail herein. It should be noted that the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “or / and” as used herein refers to any or all possible combinations including one or more of the associated listed items.

[0026] After attaching the easily installable and removable wheel-driven anti-slip and anti-sinking device to the tire, perform the first tightening action. This can be done manually by hand-cranking a handle with a matching connector or by using a hand drill to power the central gear. The central gear drives the coaxial gear of the winding wheel to rotate, which in turn drives the winding wheel to rotate via a torque limiter. At this point, the tightening rope is wound around the winding wheel. When the tightening rope is taut and the winding wheel can no longer rotate, the torque limiter cuts off torque transmission, preventing the winding wheel from rotating with the coaxial gear. The pawl engages with the ratchet teeth of the winding wheel to prevent the winding wheel from rotating in the opposite direction, stopping power transmission and completing the first tightening action. At this point, the tire's contact area with the ground prevents the tightening rope from reaching the tire sidewall closest to the vehicle body. The flexible body at this point is blocked from adhering to the tire. As the tire rotates forward or backward, the contact area between the tire and the ground changes. The blocked tightening rope then passes around the contact area between the tire and the ground and performs a second tightening action. The second tightening action is the same as the first. When the second tightening action is completed, the tightening rope tightens, and the blocked flexible body adheres tightly to the tire like other flexible bodies. At this point, the second tightening is complete. To ensure the reliability of the anti-skid and anti-sinking device that is quickly installed on the tire and to release the stress between the device and the tire, the wheel drive equipment with the device installed can be driven a sufficient distance before performing a third or more tightening actions to ensure that the flexible body adheres tightly to the tire.

[0027] When it is necessary to remove the easily installed and removed wheel-driven anti-slip and anti-sinking device from the wheel, first, by moving the pawl mechanism lever shown in Figure 1, the pawl inside the mechanical body will separate from the thorn. At this time, the winding wheel can rotate freely. By manually pulling the flexible body, the tension rope can be pulled off the winding wheel. At this point, the tension rope no longer tightens the flexible body. Except for the flexible body in contact with the ground, the other flexible bodies can be removed from the wheel. By moving the vehicle, the flexible bodies in contact with the ground will no longer be in contact with the wheel, thus completing the disassembly.
