Description

Technical Field

[0001] This invention relates to the field of vehicle traction equipment technology, specifically to portable vehicle clamp lifting traction wheel. Background Technology

[0002] The fundamental reason why vehicles get stuck is that the supporting surface cannot provide sufficient frictional reaction force to the drive wheels, resulting in minimal driving force and an inability to leave the current road surface. Therefore, traction devices can be categorized into two main types based on their primary function: increasing tire-to-ground friction and providing additional traction to the vehicle. Common traction devices such as traction boards, anti-skid blocks, and snow chains belong to the former category, while winches, tow ropes, and other devices that require additional leverage belong to the latter.

[0003] However, the aforementioned devices are not suitable for all situations where vehicles are stuck. For example, when the ground is very soft, using a traction ramp will cause the vehicle to be thrown in the opposite direction due to the rotation of the wheels, and snow chains are also ineffective. In such cases, without additional traction, the usual approach is to lift the vehicle, remove the soft ground around the stuck wheel, and then add traction ramps, gravel, or other hard materials. Furthermore, when a vehicle bottoms out, forcibly dragging it, whether using a winch or other traction devices, will damage the chassis. In addition, winches require a fixed anchor point and are ineffective for lone vehicles in vast deserts or muddy terrain. In conclusion, for a vehicle to get out of trouble more effectively, the traction device must have the function of lifting the stuck wheel while allowing the vehicle to move, so as to facilitate external assistance. When using jacks, lifting poles, airbags, etc., the vehicle cannot be moved, otherwise it is easy to cause a safety accident. Therefore, there is an urgent need to develop a new type of portable vehicle clamp lifting traction wheel. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a portable vehicle clamping and lifting auxiliary wheel for getting out of trouble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Portable vehicle clamp lifting auxiliary escape wheel, including auxiliary wheel lifting device, clamp frame, and outer pressure device; The auxiliary wheel lifting device includes a wheel frame and an auxiliary wheel. The wheel frame has an axle. The hub center of the auxiliary wheel is rotatably connected to the axle of the wheel frame. The clamping frame is slidably connected to the wheel frame in the vertical direction and is driven to rise and fall by the lifting drive mechanism. The clamping frame is provided with three or more radially arranged slide rails around its perimeter. Each slide rail is slidably connected to a roller clamping mechanism. The clamping frame is provided with a clamping drive mechanism, which drives each roller clamping mechanism to slide along the corresponding slide rail. The roller clamping mechanism includes a roller seat, a main roller, a roller shaft, an inner roller shaft rod, and an inner pressure roller. The roller seat is slidably connected to the slide rail and connected to the clamping drive mechanism. One end of the roller shaft is sleeved on the roller seat, and the main roller is rotatably sleeved on the other end of the roller shaft. The main roller is used to radially press against the cylindrical surface of the collapse wheel. One end of the inner roller shaft rod is rotatably sleeved on the end of the roller shaft near the main roller, and the inner pressure roller is rotatably sleeved on the other end of the inner roller shaft rod. The inner pressure roller is used to press against the inner side of the collapse wheel. The outer pressing device is used to press on the outside of the collapse wheel. The outer pressing device includes a pressing plate frame and an outer pressing drive mechanism. Multiple outer pressing roller pressing mechanisms are spaced apart around the pressing plate frame in the circumferential direction. The pressing plate frame is slidably connected to the clamping frame along the wheel axle and is driven by the outer pressing drive mechanism to move along the wheel axle axially.

[0006] Furthermore, the clamping drive mechanism includes a clamping motor, a flat threaded disc, a gear ring, and a gear. The back center of the flat threaded disc is rotatably connected to the clamping frame, the gear ring is fixed to the back of the flat threaded disc, and the gear is fixed to the output shaft of the clamping motor, and the gear meshes with the gear ring. Each slide rail is slidably connected to a push rod slide seat, and each push rod slide seat is connected to the corresponding roller seat through a ball joint. Each push rod slide seat is fixed with a flat threaded push rod that is threadedly engaged with the flat threaded disc.

[0007] Furthermore, one end of the roller shaft has a continuously axially arranged toothed groove on its cylindrical surface. The inside of the roller seat is connected to the roller shaft through a torsion spring plate. One side of the roller seat is connected to a displacement locking pin through a displacement compression spring. The root of the displacement locking pin has a fixed tooth that mates with the toothed groove. Under the action of the displacement compression spring, the fixed tooth at the root of the displacement locking pin presses against the toothed groove to limit the axial position of the roller shaft. The other side of the roller seat is connected to an angle locking pin through a compression spring. Under the action of the angle compression spring, the root of the angle locking pin presses against the roller shaft to restrict the rotation of the roller shaft.

[0008] Furthermore, the lifting drive mechanism includes a lifting motor, a lifting guide rail, and a lifting screw. The lifting guide rail is fixed vertically on the wheel frame, and the clamp is slidably connected to the corresponding lifting guide rail via a guide seat. The lifting screw is rotatably connected to the wheel frame in the vertical direction. The lifting motor is fixed on the wheel frame, and the output end of the lifting motor is connected to one end of the lifting screw via a belt drive mechanism.

[0009] Furthermore, the outer pressure roller clamping mechanism includes an outer pressure connecting rod, an outer pressure roller, and a follower roller. One end of the outer pressure connecting rod is rotatably connected to the outer pressure roller, and the other end of the outer pressure connecting rod is rotatably connected to the follower roller. The follower roller is rotatably connected to the corresponding guide groove on the pressure plate frame.

[0010] Furthermore, the outer pressure drive mechanism includes an outer pressure motor, multiple support guide columns, and multiple outer pressure screws. The multiple support guide columns are fixed on the clamp frame along the axial direction of the wheel axle. The pressure plate frame is fixed with guide sleeves that slide with each support guide column. The multiple outer pressure screws are rotatably connected to the clamp frame along the axial direction of the wheel axle. The outer pressure motor is fixed on the clamp frame, and the output end of the outer pressure motor drives each outer pressure screw to rotate in the same direction synchronously through a synchronous belt transmission mechanism.

[0011] The beneficial effects of this invention using the above technical solution are as follows: The portable vehicle clamp lifting auxiliary escape wheel of this invention is a novel escape device that overcomes the limitations of jacks, pole lifts, and other lifting devices that cannot be moved when lifting vehicles. The clamp structure allows the auxiliary wheel to adapt to various tire sizes, and the connection is simple, quick, stable, and reliable. Using the auxiliary wheel to lift and escape a vehicle that is completely stuck can prevent damage to the chassis structure. Installing auxiliary wheels on all wheels further facilitates towing by a rescue vehicle. Attached Figure Description

Detailed Implementation

[0013] like Figure 1-11 As shown, the portable vehicle clamp lifting auxiliary escape wheel of the present invention includes an auxiliary wheel lifting device 1, a clamp frame 2, and an outer pressure device 3.

[0014] The auxiliary wheel lifting device 1 includes a wheel frame 11 and an auxiliary wheel 12. The outer ring of the auxiliary wheel 12 is welded with a raised steel plate rim and rubber blocks. Its shape can be customized according to the usage scenario, which can increase the friction coefficient between the auxiliary wheel 12 and the ground. In addition, if the auxiliary wheel 12 is designed as a hub motor, it can lift the collapsed wheel and drive it to get out of trouble. The wheel frame 11 has an axle 13. The hub center of the auxiliary wheel 12 is rotatably connected to the axle 13 of the wheel frame 11. The clamping frame 2 is slidably connected to the wheel frame 11 in the vertical direction and is driven to rise and fall by the lifting drive mechanism. The lifting drive mechanism includes a lifting motor 14, a lifting guide rail 15, and a lifting screw 16. The lifting guide rail 15 is fixed vertically to the wheel frame 11. The clamping frame 2 is slidably connected to the corresponding lifting guide rail 15 via a guide seat. The lifting screw 16 is rotatably connected to the wheel frame 11 vertically. The lifting motor 14 is fixed to the wheel frame 11, and its output end is connected to one end of the lifting screw 16 via a belt drive mechanism. After each tire clamping roller is securely fixed to the collapsed wheel being rescued, the lifting motor 14 drives the screw structure to rotate, and the auxiliary wheel 12 moves along the lifting guide rail 15 towards the ground. When the auxiliary wheel 12 contacts the ground, it continues to move downwards, and under the relative action of forces, the collapsed wheel is lifted.

[0015] In this invention, there are two sets of lifting drive mechanisms. Each lifting screw 16 is driven by a lifting motor 14. Belt drive can compensate for transmission errors caused by the asynchronous operation of the two lifting screws 16. In case of overload, the slippage of the belt drive provides overload protection. The auxiliary wheel 12 is connected to the axle 13 via bearings and can rotate freely relative to the axle 13. Therefore, the vehicle can still move after the collapsed wheel is lifted.

[0016] The clamping frame 2 has three or more radially arranged slide rails 21 around its perimeter. In this invention, the clamping frame 2 has four slide rails 21 arranged at equal intervals along the circumferential direction. Each slide rail 21 is slidably connected to a roller clamping mechanism 4. The clamping frame 2 is provided with a clamping drive mechanism 5, which drives each roller clamping mechanism 4 to slide along the corresponding slide rail 21. The roller clamping mechanism 4 includes a roller seat 41, a main roller 42, a roller shaft 43, an inner roller shaft 44, and an inner pressure roller 45. The roller seat 41 is slidably connected to the slide rail 21 and connected to the clamping drive mechanism 5. One end of the roller shaft 43 is sleeved on the roller seat 41, and the main roller 42 is rotatably sleeved on the other end of the roller shaft 43. The main roller 42 is used to radially press against the cylindrical surface of the collapsing wheel. One end of the inner roller shaft 44 is rotatably sleeved on the end of the roller shaft 43 near the main roller 42, and the inner pressure roller 45 is rotatably sleeved on the other end of the inner roller shaft 44. The inner pressure roller 45 is used to press against the inner side of the collapsing wheel.

[0017] The clamping drive mechanism 5 includes a clamping motor 51, a flat threaded disc 52, a gear ring 53, and a gear. The back center of the flat threaded disc 52 is rotatably connected to the clamping frame 2. The gear ring 53 is fixed to the back of the flat threaded disc 52, and the gear is fixed to the output shaft of the clamping motor 51, meshing with the gear ring 53. Each slide rail 21 has a push rod slide 54 slidably connected inside, and each push rod slide 54 is connected to the corresponding roller seat 41 via a ball joint 55. Each push rod slide 54 has a flat threaded push rod 56 fixed on it, which is threadedly engaged with the flat threaded disc 52. To make the sliding of the push rod slide 54 and the roller seat 41 smoother, the slide rail 21 can be designed with coarse serrations, which can reduce the contact friction surface. At the same time, a certain amount of grease can be stored in the tooth grooves of the slide rail 21. When the push rod slide 54 moves on the slide rail 21, it will synchronously drive the roller clamping mechanism 4 to move radially. Considering the self-locking nature of the clamping structure, the push rod slide 54 is driven by a planar thread structure, with the planar thread push rod 56 fixedly mounted above the push rod slide 54. A planar threaded disc 52 is arranged in the middle of the clamping frame 2. The rotational motion of the planar threaded disc 52 is converted into the linear motion of the push rod slide 54 via the planar threaded push rod 56. A set of internal meshing gears is mounted on the planar threaded disc 52. Power from the clamping motor 51 is input from the gears to the gear ring 53, thereby causing the gear ring 53 to drive the planar threaded disc 52 to rotate.

[0018] Because different vehicle tires have different widths, the length of the extended roller shaft 43 needs to be adjusted to accommodate different tire widths. The specific adjustment structure is as follows: One end of the roller shaft 43 has a continuously axially arranged toothed groove 431 on its cylindrical surface. The inside of the roller seat 41 is connected to the roller shaft 43 through a torsion spring plate 46. One side of the roller seat 41 is connected to a displacement locking pin 47 through a displacement compression spring. The root of the displacement locking pin 47 has a fixed tooth that mates with the toothed groove 431. Under the action of the displacement compression spring, the fixed tooth at the root of the displacement locking pin 47 presses against the toothed groove 431 to limit the axial position of the roller shaft 43. The other side of the roller seat 41 is connected to an angle locking pin 48 through a compression spring. Under the action of the angle compression spring, the root of the angle locking pin 48 presses against the roller shaft 43 to restrict the rotation of the roller shaft 43. When it is necessary to adjust the extension length of the roller shaft 43, pull the shift locking pin 47 knob outward and rotate it at a certain angle to lock the shift locking pin 47 knob (the stop pin on the shift locking pin 47 rotates out of the guide pin groove and blocks the shift locking pin 47 from moving down). At this time, the shift locking pin 47 will disengage from the tooth groove 431, and the roller shaft 43 can move. After moving to the corresponding position, release the shift locking pin 47 to fix the roller shaft 43 again.

[0019] This invention comprises four main rollers 42 for clamping onto the traction wheel. The surface of each main roller 42 is covered with wear-resistant rubber, and each roller can rotate around a roller shaft 43. When the traction wheel is the drive wheel, this structure allows unimpeded rotation. In this case, if the vehicle has a differential lock, power can be distributed to the other wheel with sufficient traction. However, if the main rollers 42 cannot rotate, and the device is tightly clamped onto the traction wheel, the rotation of the traction wheel will cause the auxiliary traction wheel to rotate as well, which could easily lead to an accident.

[0020] The inner roller shaft 44 is equipped with a freely rotatable inner pressure roller 45. Initially, the inner roller shaft 44 is positioned at a certain angle to the outside so that the auxiliary wheel 12 can be fitted onto the collapsing wheel. After fitting, the inner pressure roller 45 swings towards the axis, causing it to lock onto the inner side of the tire of the collapsing wheel. At this point, the auxiliary wheel 12 cannot be pulled out.

[0021] The swing of the inner pressure roller 45 is integrated with the inner roller shaft 44, and the swing angle is related to the roller slide device at the shaft end. The roller seat 41 cooperates with the roller shaft 43, and the two can also rotate relative to each other. The roller seat 41 is provided with a lubricating oil channel for grease. The inside of the roller seat 41 is connected to the roller shaft 43 through a torsion spring plate 46. Under the action of the torsion spring plate 46, the roller shaft 43 is maintained in its current position, and the inner roller shaft 44 will be in an initial state of swinging outward at a certain angle. After the device is fitted with the collapsing wheel, the inner roller shaft 44 can be rotated towards the axis, at which time the torsion spring plate 46 is compressed and stores force. After the shaft is turned to point towards the axis, the angle locking pin 48 located on the roller seat 41 will be locked in the tooth groove 431 of the roller shaft 43 under the action of the internal angle compression spring, and the roller shaft 43 together with the inner roller shaft 44 will be fixed on the roller seat 41 and cannot be rotated anymore. When the auxiliary escape wheel needs to be removed, pulling up the knob above the angle locking pin 48 will cause the angle locking pin 48 to disengage from the groove. Under the action of the torsion spring plate 46, the roller shaft 43 and the inner roller shaft 44 will return to their initial outward swinging state.

[0022] After the four main rollers 42 are fitted into the collapsing wheel and the inner pressure roller 45 is fixed in place, the outer pressure device 3 presses against the tire from the outside, thus better securing the auxiliary wheel 12 to the collapsing wheel. The outer pressure device 3 includes a pressure plate frame 31 and an outer pressure drive mechanism 32. Multiple outer pressure roller pressing mechanisms 33 are spaced circumferentially around the pressure plate frame 31. The pressure plate frame 31 is slidably connected to the clamping frame 2 along the wheel axle 13 and is driven by the outer pressure drive mechanism 32 to move axially along the wheel axle 13. The outer pressure roller pressing mechanism 33 includes an outer pressure connecting rod 331, an outer pressure roller 332, and a follower roller 333. One end of the outer pressure connecting rod 331 is rotatably connected to the outer pressure roller 332, and the other end is rotatably connected to the follower roller 333. The follower roller 333 is rolled on the corresponding guide groove on the pressure plate frame 31.

[0023] The outer pressure drive mechanism 32 includes an outer pressure motor 321, multiple support guide columns 322, and multiple outer pressure screws 323. The multiple support guide columns 322 are fixed to the clamp frame 2 along the axial direction of the wheel axle 13. The pressure plate frame 31 is fixed with guide sleeves that slide with each support guide column 322. The multiple outer pressure screws 323 are rotatably connected to the clamp frame 2 along the axial direction of the wheel axle 13. The outer pressure motor 321 is fixed to the clamp frame 2, and the output end of the outer pressure motor 321 drives each outer pressure screw 323 to rotate in the same direction synchronously through the synchronous belt drive mechanism 324. When the outer pressure motor 321 starts, the four driven pulleys drive the corresponding outer pressure screws 323 to rotate under the action of belt drive. At this time, the pressure plate frame 31 will move axially along the support guide columns 322, driving the follower wheel to move. After being driven by the outer pressure connecting rod 331, the outer pressure roller 332 can complete the action of pressing inward or releasing outward.

[0024] To reduce wear on sliding components caused by mud and sand, corrugated telescopic rubber sleeves can be installed at both ends of lead screws and slide rails; the screw drive structure can be customized with scrapers and covers to surround it, reducing the inflow of mud and sand; since the motors do not operate under high load for extended periods, the heat dissipation requirements are not high. Therefore, the control circuit board can be sealed or potted, and the motors should be equipped with high IP protection ratings and have protective covers added.

[0025] The motor control circuit board of this portable vehicle clamp lifting and traction wheel device is mounted on the clamp frame and is mainly responsible for controlling the clamp motor, lifting motor, and outer pressure motor. All motors are 48V DC motors; however, due to limited internal space, a battery pack cannot be installed, so an external DC power supply is required for operation. Wireless control is used, allowing users to adjust the lifting height in real time based on the vehicle's current position. The circuit board has an overload protection module that disconnects the circuit when excessive drive current is detected.

[0026] When not in use, this portable vehicle clamp lifting auxiliary wheel device can be mounted on the luggage compartment or roof rack of an off-road vehicle. When the vehicle becomes stuck, it can be removed and installed on the stuck wheel (by clamping the main roller, inner pressure roller, and outer pressure roller into the tire respectively). Then, the stuck wheel is lifted, and the auxiliary wheel will replace the stuck wheel in contact with the ground. This allows the vehicle to remain movable after being lifted, and then subsequent towing operations can be carried out.

[0027] If this portable vehicle clamp lifting assist wheel is carried in a vehicle, a DC booster needs to be installed on the vehicle to raise the 12V voltage to the motor's rated voltage; an inverter can also be used for conversion. When paired with a tracked vehicle, this assist wheel can be deployed as a professional rescue device. The tracked vehicle can travel in various complex road conditions, transporting the assist wheel to the vicinity of the stranded vehicle, while its own battery pack directly supplies power to the assist wheel. Furthermore, after the assist wheel is installed on the tires of the stranded vehicle, the tracked vehicle can tow the vehicle.

[0028] The specific embodiments of the present invention have been described above. However, those skilled in the art should understand that this is merely an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principles and essence of the present invention, but all such changes and modifications fall within the protection scope of the present invention.
