Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle safety auxiliary equipment, specifically relating to an integrated device for preventing vehicles from slipping and sliding, and for self-rescue and getting out of trouble. Background Technology

[0002] When vehicles travel on icy, snowy, or slippery roads, the significantly reduced coefficient of friction between the tires and the road surface often leads to decreased braking efficiency, loss of acceleration, and extended braking distances. This can even cause skidding and rollovers, posing a serious threat to driving safety. While existing truck braking systems can meet braking requirements on regular roads, their effectiveness drops drastically during emergency braking on low-friction surfaces like ice, snow, and slippery surfaces. This can cause vehicles to lurch forward for extended periods and lose control, especially under heavy loads, on slopes, and in mountainous areas, where the risk of accidents is even more pronounced.

[0003] To address these issues, current solutions often focus on modifying tires beforehand or adding auxiliary anti-skid features, such as installing snow chains, inserting anti-skid teeth, installing metal anti-skid shells, or using tire pads to prevent slippage. While these methods improve tire-road adhesion to some extent, they still have significant drawbacks: snow chains and similar devices can easily damage tires, are inconvenient to install and remove, and have poor adaptability to intermittent icy and snowy road conditions; furthermore, these measures are functionally limited and structurally redundant, becoming a burden to driving in non-icy and snowy environments, thus limiting their overall practicality.

[0004] Especially in extreme conditions such as frigid regions and steep, icy roads, vehicles not only face the risk of brake failure but may also experience emergencies such as tire blowouts and getting stuck. Existing technologies lack integrated emergency support capabilities. Therefore, there is an urgent need for a multi-functional device that integrates anti-skid, hill-start assist, tire blowout self-rescue, and obstacle-avoidance functions to comprehensively improve vehicle driving safety and emergency response capabilities in complex environments. Summary of the Invention

[0005] The purpose of this utility model is to provide an integrated device for preventing vehicles from slipping and escaping from difficult situations. This device integrates anti-skid, slope parking, tire blowout self-rescue and escaping functions, comprehensively improving the driving safety and emergency handling capabilities of vehicles in complex environments.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An integrated device for preventing vehicles from slipping and skidding, and for self-rescue and getting out of trouble, includes:

[0008] The parking shovel assembly is hinged to the rear of the vehicle's longitudinal beam via a first articulation shaft;

[0009] A support leg assembly, which is hinged to the parking shovel assembly;

[0010] The first drive mechanism has one end hinged to the vehicle longitudinal beam and the other end hinged to the parking shovel assembly, and is used to drive the parking shovel assembly to rotate around the first hinge axis, so that it has a retracted state under the vehicle and an extended working state.

[0011] The second drive mechanism is disposed between the parking shovel assembly and the support leg assembly, and is used to drive the support leg assembly to unfold or retract relative to the parking shovel assembly.

[0012] The power unit, mounted on the vehicle body, provides power to the first and second drive mechanisms.

[0013] The control unit is electrically connected to the power unit and is used to receive instructions and control the actions of the first drive mechanism and the second drive mechanism.

[0014] Specifically, when the support leg assembly is extended downwards to a vertical position, the lower end of the support leg assembly is lower than the lower end of the parking shovel assembly.

[0015] Preferably, the first drive mechanism and / or the second drive mechanism is a hydraulic cylinder, an electric push rod, or a pneumatic cylinder.

[0016] Preferably, the parking shovel assembly includes: a left bracket and a right bracket, the upper ends of which are hinged to the vehicle longitudinal beam via the first hinge shaft; an upper crossbeam laterally connected between the left and right brackets; a lower shovel plate laterally fixed to the lower ends of the left and right brackets; and a plurality of shovel teeth mounted on the lower shovel plate.

[0017] Preferably, the support leg assembly includes: a left support leg and a right support leg, respectively hinged to the left and right sides of the parking shovel assembly; and a lower crossbeam laterally connected between the left and right support legs.

[0018] Preferably, the ends of the shovel teeth are conical or wedge-shaped and are inclined toward the ground.

[0019] Preferably, the shovel teeth are detachably mounted on the lower shovel plate via a pin.

[0020] Preferably, the power unit is a vehicle battery, and also includes a hydraulic pump station connected to the vehicle battery for providing pressurized oil to the hydraulic cylinder-type drive mechanism.

[0021] Preferably, the control unit is a wired remote control or a wireless remote control.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] 1. Highly integrated functions, multi-purpose: It creatively integrates three major functions—emergency braking, emergency lifting (jack), and assisted escape—into one device, solving the problems of previous equipment having single functions and insufficient ability to cope with complex situations, and achieving comprehensive protection for vehicles in various emergency situations.

[0024] Ensuring safety and reliability in extreme working conditions: In harsh environments such as icy and snowy slopes (slope ≤35%) in frigid regions where traditional braking systems are prone to failure, the hydraulic drive forcefully embeds the shovel teeth into the ground, providing mechanical emergency braking, effectively suppressing vehicle sideslip and slippage, and greatly improving driving safety.

[0025] Significantly improves emergency repair and self-rescue efficiency: In the event of a tire blowout or other malfunction, the device can be quickly converted into an emergency jack to directly lift the rear of the vehicle, eliminating the tedious process and time of finding and placing a traditional jack. Especially in harsh environments, it significantly shortens the repair time and ensures the smooth progress of the mission.

[0026] Robust structure and wide applicability: The core structure of this device is based on the robust longitudinal beams of a vehicle, providing strong load-bearing capacity. The detachable, pointed conical shovel design ensures excellent ground penetration and durability while facilitating replacement and maintenance. This device is not only suitable for camping vehicles but can also be widely installed on various trucks and special vehicles, demonstrating high versatility.

[0027] Easy to operate and quick to respond: Controlled by wired or wireless remote control, the driver can safely and conveniently operate all functions from inside the vehicle. The response is fast, enabling effective intervention in the first instance in an emergency.

[0028] In the event of a rear-end collision involving a sedan, the parking shovel assembly and support legs can act as a rear bumper, preventing the front of the following vehicle from crashing into the underside of the rear vehicle, thus reducing the risk of injury to the following vehicle.

[0037] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0038] See Figures 1 to 6 As shown in the figure, this embodiment provides an integrated device for preventing vehicles from slipping and escaping from side slipping. It is fixedly installed at the rear of the longitudinal beam 10 of the chassis of a campervan or truck through multiple hinge seats and fasteners.

[0039] The vehicle anti-slippage self-rescue integrated device mainly includes a parking shovel assembly, a support leg assembly, a drive system, a power unit, and a control unit.

[0040] The parking shovel assembly includes a left support 21, a right support 22, an upper crossbeam 23, a lower shovel plate 24, and shovel teeth 25. The upper ends of the left support 21 and the right support 22 are symmetrically hinged to both sides of the rear of the vehicle longitudinal beam 10 via a first hinge seat 101. The upper crossbeam 23 is horizontally welded and fixed to the upper middle part of the left and right supports 21 and 22, serving to strengthen the structural rigidity. The lower shovel plate 24 is horizontally welded and fixed to the lower end of the left and right supports 21 and 22. The shovel teeth 25 are conical structures, six in total, and are detachably installed in shovel tooth seats provided on the lower shovel plate 24 via shovel tooth pins 26. The tips of all shovel teeth 25 are inclined towards the ground to facilitate cutting into hard or icy surfaces.

[0041] The support leg assembly includes a left support leg 31, a right support leg 32, and a lower crossbeam 33. The upper end of the left support leg 31 is hinged to the lower middle part of the left bracket 21 via a fourth hinge seat 34; correspondingly, the upper end of the right support leg 32 is hinged to the lower middle part of the right bracket 22. The lower crossbeam 33 is horizontally welded and fixed between the left and right support legs 31 and 32 to enhance the overall stability of the support leg assembly.

[0042] The drive system includes a first drive mechanism and a second drive mechanism. The first drive mechanism consists of a left hydraulic cylinder 41 and a right hydraulic cylinder 42. The upper end of the left hydraulic cylinder 41 is hinged to the left longitudinal beam via a second hinge seat 102, and its lower end is hinged to the middle of the left support 21 via a third hinge seat. The right hydraulic cylinder 42 is symmetrically arranged, with its upper end hinged to the right longitudinal beam and its lower end hinged to the middle of the right support 22. The left and right hydraulic cylinders 41 and 42 operate synchronously to drive the entire parking shovel assembly to swing downwards to the working position or upwards to the retracted position around the first hinge seat 101.

[0043] The second drive mechanism is an intermediate hydraulic cylinder 43. The upper end of the intermediate hydraulic cylinder 43 is hinged to the middle of the upper crossbeam 23 of the parking shovel assembly, and the lower end is hinged to the middle of the lower crossbeam 33 of the support leg assembly. The extension and retraction of the intermediate hydraulic cylinder 43 is used to drive the support leg assembly to extend downward or retract upward around its hinge points with the left and right brackets 21 and 22.

[0044] The power unit is a hydraulic pump station, which is fixedly mounted on the vehicle's main beam via a bracket. The hydraulic pump station is connected to the left hydraulic cylinder 41, the right hydraulic cylinder 42, and the middle hydraulic cylinder 43 via hydraulic lines. The power source for the hydraulic pump station is the vehicle's original onboard battery.

[0045] The control unit is a wireless remote controller electrically connected to the hydraulic pump station. The driver can send commands from inside the cab or outside the vehicle via buttons on the remote controller to control the individual or coordinated movements of each hydraulic cylinder.

[0046] The overall working principle and process of this utility model are as follows:

[0047] 1. Emergency Braking Mode (Anti-Slip, Anti-Slip): When the vehicle slips or the brakes fail on an icy or snowy slope, the driver controls the left and right hydraulic cylinders 41 and 42 to extend simultaneously via remote control, pushing the parking shovel assembly downwards to rotate around the first hinge seat 101 until the shovel teeth 25 forcefully embed themselves into the ground at a certain angle. At this time, the huge friction between the lower shovel plate 24 and the shovel teeth 25 and the ground can effectively prevent the vehicle from continuing to slip or slide, achieving emergency braking.

[0048] Emergency Lifting Mode (Used as a Jack): When a tire blows out and needs to be replaced, first, control the extension of the central hydraulic cylinder 43 to push the support leg assembly downwards. Then, control the left and right hydraulic cylinders 41 and 42 to extend simultaneously via remote control, pushing the parking shovel assembly downwards and rotating it around the first hinge seat 101, lowering the support leg assembly until the left support leg 31 and right support leg 32 contact the ground. Since the support leg assembly is hinged to the bracket, its downward rotation forces the entire parking shovel assembly to use its contact point with the ground as a fulcrum, lifting the rear of the vehicle's longitudinal beam 10 upwards in the opposite direction, thereby lifting the disabled wheel off the ground and functioning as an emergency jack.

[0049] Assisted Extrication Mode: When the vehicle is stuck in mud, sand, or other difficult conditions, the parking shovel assembly and / or support leg assembly can be lowered to the ground. The sturdy shovel and / or support legs provide additional support and friction to the wheels, allowing for the filling of stones or other objects into the rear wheels, or using them as a fulcrum for towing, thus assisting the vehicle in getting out of trouble.

[0050] In this embodiment, when the support leg assembly is fully lowered to the vertical position by the intermediate hydraulic cylinder 43, the lowest points of its left support leg 31 and right support leg 32 are lower than the tips of the shovel teeth 25, so as to ensure that the vehicle body can be effectively lifted in the lifting mode.

[0051] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
