Description

Technical Field

[0001] The invention belongs to the field of wheel drive, and in particular relates to a wheel drive anti-skid and anti-sinking device which is easy to install and disassemble and an execution program thereof. Background Art

[0002] Wheel drive has been widely used in various fields in today's society, mainly in the form of various transportation vehicles, from ordinary road traffic to the forefront of science and technology Mars and lunar exploration, there are wheel drives, and wheel drive vehicles can also be seen in harsh environments such as polar regions, Gobi, deserts and rainforests. Wheel drive has greatly expanded the scope of human activities. At present, even vehicles known for their off-road performance will still have problems with losing adhesion to the ground, sinking in soft geology, and cutting tires on gravel roads when facing harsh outdoor environments, trapping people and vehicles, increasing exposure to outdoor environments, and increasing danger. At the same time, while ensuring road comfort and fuel economy, wheel drive vehicles at this stage are difficult to take into account the applicability in harsh environments. When faced with freezing rain and snowfall weather causing low ground adhesion, the vehicle cannot drive normally, and the tires slip, the braking distance increases, or the body shifts sideways during driving, which can easily cause traffic accidents. The above problems limit the properties of vehicles for use in multiple environments and scenarios.

[0003] In the case of wheel-driven vehicles losing adhesion to the ground and getting stuck in soft ground during off-road driving, the existing solution is to install a winch or a rescue board. When the vehicle is trapped, using the built-in winch or rescue board for rescue is a post-event remedy, which cannot be prepared in advance. The flexibility of use is poor, and this trapped and rescue method wastes time and physical strength. The existing installation device cannot solve the anti-skid and anti-sinking problems at the same time, does not have the attribute of one thing for multiple uses, and cannot meet the multi-task requirements in multiple scenarios; when facing environments such as gravel roads that are easy to damage tires, there is no targeted solution at this stage. In order to solve the problem of low ground adhesion in freezing rain and snowy weather, the problem should be solved from two aspects: increasing friction and increasing contact area. The existing solution only solves the problem by changing the contact surface to increase friction, and there is no solution that combines increasing contact area and increasing friction. At the same time, the existing solutions and products are cumbersome to operate and take a long time to install. Some products require operators to have certain hands-on skills, and some products require operators to have physical strength, which is not very friendly to women. Summary of the invention

[0004] In order to deal with the above situation, the present invention adopts a wheel-type drive anti-skid and anti-sinking device that is easy to install and disassemble, and cooperates with its execution program to solve the problems of low adhesion and vehicle sinking by increasing the friction per unit area and increasing the contact area with the ground, and also protects the tire tread and sidewall. Its convenient installation and disassembly is also an important feature of the present invention. It is easy to install and disassemble, and it takes a short time to better protect the safety of people and property in the wild environment.

[0005] The present invention adopts the following technical scheme:

[0006] The invented wheel-type driven anti-skid and anti-sinking device which is easy to install and disassemble comprises a central mechanical body, a flexible body connected to the central mechanical body, a tightening rope which passes through all the blades of the flexible body and enters the central mechanical body, and an execution program.

[0007] The central mechanical body comprises a winding wheel, a torque limiter, a winding wheel coaxial gear, a ratchet, a ratchet lever mechanism, and a central gear.

[0008] The torque limiter is located between the winding wheel and the winding wheel coaxial gear, and the winding wheel coaxial gear drives the winding wheel to rotate through the torque limiter.

[0009] The flexible body has a protrusion, and the protrusion increases the contact area between the flexible body and the ground.

[0010] The flexible body has multiple blades, and the blades of the flexible body are divided into two forms: multiple through-hole flexible body blades and single through-hole flexible body blades. The difference between the two forms is that there are different through holes on the flexible body blades. The multiple through-hole flexible body blades are characterized by: one end is connected to the mechanical body, and the end has two through-hole openings, and the two through-hole openings are respectively connected to the two through-hole openings at the other end, and the other end has at least one through hole in addition to the through-hole opening connected to the mechanical end, and the two openings of the through-hole are located on the opposite sides with smaller cross-sectional dimensions, and the tightening rope passes through the above-mentioned holes; the single through-hole flexible body blades are characterized by: one end is connected to the mechanical body, and the other end has a through hole, and the through hole has at least one through hole at the end, and the two openings of the through hole are located on the opposite sides with smaller cross-sectional dimensions, and the tightening rope passes through the hole.

[0011] 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 the central mechanical body, and the two ends of the same tightening rope can be respectively connected and fixed to the two winding wheels, and the two ends of the same tightening rope can also have one end pass through the determined multiple through-hole flexible body fan blades to enter the central mechanical body and be connected to the winding wheel, and the other end is fixed on the determined multiple through-hole flexible body fan blades. When the tightening action is performed, the tightening rope is wound around the winding wheel, and the tightening rope drives the flexible body when performing the tightening action, so that the flexible body is tightly attached to the side wall of the tire.

[0012] The execution procedure of the wheel-driven anti-skid and anti-sinking device which is easy to install and disassemble is as follows: after the wheel-driven anti-skid and anti-sinking device which is easy to install and disassemble is put on the tire, the first tightening action is performed, and the power can be provided by manually holding a hand crank with a matching socket or a hand drill to rotate the central gear, and the central gear drives the coaxial gear of the winding wheel to rotate, and the coaxial gear drives the winding wheel to rotate through the torque limiter. At this time, the tightening rope is wound around the winding wheel, and when the tightening rope is tightened and the winding wheel cannot continue to rotate, the torque limiter cuts off the torque transmission, and the winding wheel cannot rotate together with the coaxial gear of the winding wheel, and the ratchet pawl cooperates with the ratchet teeth 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 time, the contact part between the tire and the ground blocks the tightening rope from reaching the vicinity The tire sidewall on one side of the vehicle body also blocks the flexible body in that part from sticking closely to the tire. By rotating the tire as it moves forward or backward, the contact point between the tire and the ground changes. The blocked tightening rope bypasses the contact point between the tire and the ground, and then 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 is tightened, and the blocked flexible body sticks closely to the tire like other flexible bodies. At this time, 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 that is quickly installed on the tire and the tire, the wheel drive equipment on which the device is installed can be driven a sufficient distance, and then a third or more tightening actions can be performed to ensure that the flexible body fits closely to the tire.

[0013] The wheel-type drive anti-skid and anti-sinking device proposed by the present invention, which is easy to install and disassemble, has the following beneficial effects:

[0014] Compared with similar products with single functions and limited usage environment, the present invention increases the contact area between the wheel-driven vehicle and the ground, playing the dual functions of anti-skid and anti-sinking; in terms of usage environment, it can be used in non-paved road environments such as sand, mud, gravel, and can also be used in snowy and icy road environments in winter, playing a role in a variety of scenarios.

[0015] In harsh outdoor environments, when there is a risk of the car being stuck, other product solutions all require rescue after the car is stuck, and fail to take measures to avoid the risk in advance. Compared with other products, the present invention can be used for rescue and can also be installed in advance to avoid the risk of the car being stuck, while providing certain protection for the tires.

[0016] When an off-road vehicle needs to pass through different environments such as roads and unpaved roads, it is inconvenient to change tires, and the vehicle can only choose off-road tires at the expense of comfort and fuel economy. The advantage of the present invention is that the vehicle uses ordinary tires on roads, and the problem can be solved by installing the present invention when entering unpaved roads from roads.

[0017] The present invention is easy to operate while ensuring reliability and safety: the inner side tightening operation is transferred from the relatively narrow space between the wheel and the vehicle body to the side of the wheel relatively far from the vehicle body, which is simple and convenient to operate; by adding a hand electric drill with a matching socket as power, physical strength is saved and convenience is improved.

DETAILED DESCRIPTION

[0028] Exemplary embodiments will be described in detail here, and it should be noted that the present invention can be implemented in a variety of different forms and is not limited to the implementation cases described herein. The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "or / and" used herein refers to any or all possible combinations of one or more associated listed items.

[0029] After putting the easy-to-install wheel-driven anti-skid and anti-sinking device on the tire, perform the first tightening action. The power can be provided by manually holding a hand crank with a matching socket or an electric drill to rotate the central gear. The central gear drives the coaxial gear of the winding wheel to rotate, and the coaxial gear drives the winding wheel to rotate through the torque limiter. At this time, the tightening rope is wound around the winding wheel. When the tightening rope is tightened and the winding wheel can no longer rotate, the torque limiter cuts off the torque transmission, and the winding wheel cannot rotate with the coaxial gear of the winding wheel. The pawl cooperates 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 time, the contact point between the tire and the ground blocks the tightening rope from reaching the tire sidewall close to the vehicle body. The flexible body blocking this part is close to the tire, and the contact part of the tire with the ground changes through the rotation of the tire moving forward or backward. The blocked tightening rope bypasses the contact part of the tire with the ground, and then 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 is tightened, and the blocked flexible body is close to the tire like other flexible bodies. At this time, 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 release the stress between the anti-skid and anti-sinking device that is quickly installed on the tire and the tire, the wheel drive equipment equipped with the device can be driven a sufficient distance, and then the third or more tightening actions can be performed to ensure that the flexible body fits tightly to the tire.

[0030] When you need to remove the easy-to-install wheel drive anti-skid and anti-sinking device from the wheel, first Figure 1 The ratchet mechanism lever shown in the figure separates the ratchet in the mechanical body from the thorn, and the winding wheel can rotate freely at this time. By manually pulling the flexible body, the tension rope is pulled off the winding wheel. At this time, the tension rope no longer tightens the flexible body, and the other flexible bodies except the flexible body in contact with the ground can be removed from the wheel. By moving the vehicle, the flexible body in contact with the ground is no longer attached to the wheel, and the disassembly is completed.
