Description

Technical Field

[0001] This invention relates to the field of reinforcement device technology, and in particular to a composite structure wheel riser block and its preparation method. Background Technology

[0002] Lifting blocks are common rigid or semi-rigid supports primarily used to raise objects to a specific height or fill gaps during various operations. They are particularly crucial in vehicle repair, maintenance, and inspection, where they are frequently used to safely lift and securely support vehicle tires for tasks such as chassis repair and tire changes. These lifting blocks typically feature a structure with gently sloping sections at one or both ends, allowing vehicle tires to smoothly drive onto them, thus achieving the lifting purpose.

[0003] Existing wheel jacks are not effective at preventing wheels from slipping unexpectedly when working on inclined surfaces, resulting in poor safety. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a composite structure wheel riser block, which can effectively prevent the wheel from slipping unexpectedly and has good safety.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A composite structure wheel riser block, comprising:

[0007] The raised block body has an inclined part and a raised part, the inclined part and the raised part are connected in sequence along the driving direction of the wheel, and the inclined part is used for the wheel to climb uphill or downhill.

[0008] An anti-reverse rotation shaft is hinged to the raised portion and located at the top of the raised portion;

[0009] The first anti-reverse structure includes a first one-way rotating interceptor and a first ratchet. One of the first one-way rotating interceptor and the first ratchet is disposed on the body of the raised block, and the other is disposed on the anti-reverse rotating shaft. The first one-way rotating interceptor abuts against the first ratchet to prevent the anti-reverse rotating shaft from generating a rotational inertia that moves forward in the driving direction.

[0010] Furthermore, the first ratchet is sleeved on the anti-reverse rotation shaft and rotates with the anti-reverse rotation shaft; the hinged end of the first one-way rotation interceptor is hinged to the body of the shim block, and the swinging end of the first one-way rotation interceptor abuts against the first ratchet; the body of the shim block has a first support block, the first support block is located on the swinging trajectory of the first one-way rotation interceptor and is used to assist the first support block in preventing the first ratchet from rotating.

[0011] Furthermore, the raised block body also has a travel limiting part, the inclined part and the raised part are connected in sequence along the wheel and the travel limiting part along the driving direction of the wheel, the top height of the travel limiting part is greater than the height of the raised part, and is used to prevent the wheel from leaving the raised part along the driving direction.

[0012] Furthermore, the composite structure wheel riser also includes a second anti-reverse structure, which includes a second one-way rotating interceptor, a second ratchet, and a push-pull rod. One of the second one-way rotating interceptor and the second ratchet is located on the riser body, and the other is located on the anti-reverse rotating shaft. The second one-way rotating interceptor abuts against the second ratchet to prevent the anti-reverse rotating shaft from generating rotational inertia near the inclined portion. The push-pull rod connects the second one-way rotating interceptor or the second ratchet and is movably inserted into the riser body so that the second one-way rotating interceptor and the second ratchet can translate relative to each other along the axial direction of the second one-way rotating interceptor, thereby causing the second one-way rotating interceptor and the second ratchet to abut against each other or disengage from each other.

[0013] Furthermore, the raised block body is provided with a second support block, which is located on the swing trajectory of the second unidirectional rotating interceptor bar and is used to assist the second support block in preventing the first ratchet from rotating.

[0014] Furthermore, the raised portion has a mounting groove, the opening of which is recessed downward from the top of the raised portion. The anti-reverse rotating shaft is installed in the mounting groove, the anti-reverse rotating shaft is housed in the mounting groove, and the top of the anti-reverse rotating shaft extends out from the inside of the mounting groove along the opening. The top of the raised portion is provided with a speed bump, and the anti-reverse rotating shaft and the speed bump are arranged sequentially along the driving direction of the wheel.

[0015] Furthermore, the anti-reverse rotation shaft is fitted with a bearing, which is installed on the raised portion.

[0016] Furthermore, the composite structure wheel riser block also includes at least two side baffles, which are installed above the riser portion and supported by the riser portion; the side baffles extend along the horizontal extension direction of the two riser portions, and the two side baffles are disposed opposite each other on the horizontal opposite sides of the riser portion.

[0017] Furthermore, the side baffle is provided with drainage holes that extend axially along the rotation axis; multiple drainage holes are provided that extend along the length direction of the raised block body.

[0018] Furthermore, EP300 type canvas is layered to form the body of the raised block; or, 4 layers of steel mesh and 2 layers of 2000 type DPP aramid canvas are used, with the remainder made of EP300 type canvas, wherein the EP300 type canvas is layered, and the 4 layers of steel mesh and 2 layers of 2000 type DPP aramid canvas are evenly distributed in the canvas layers to form the body of the raised block.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The raised block body has an inclined section and a raised section, which are connected sequentially along the wheel's driving direction. The inclined section is used for the wheel to climb or descend slopes. The raised section structure allows the wheel to rise to the required height smoothly and effortlessly, avoiding violent impact between the wheel and the edge of the raised block, thus protecting the tire and making operation smoother. The raised section provides a stable horizontal parking platform for the raised wheel, ensuring the vehicle's center of gravity is stable in the raised state, facilitating tire changing, inspection, and other operations. The sequential connection of the two along the wheel's driving direction enforces the spatial order of the inclined section in front and the raised section behind, providing the necessary prerequisite for the correct triggering and effectiveness of the subsequent anti-rollover function.

[0021] 2. The anti-skid rotating shaft is hinged to the raised part and located at the top of the raised part. Traditional raised blocks rely on the static friction between the tire and the surface of the fixed block for anti-skid performance, which is unreliable. The anti-skid rotating shaft can control the difficulty of the wheel passing through by rotating.

[0022] 3. The first anti-reverse structure includes a first one-way rotating interceptor and a first ratchet. One of the first one-way rotating interceptor and the first ratchet is located on the body of the raised block, and the other is located on the anti-reverse rotating shaft. The first one-way rotating interceptor abuts against the first ratchet to prevent the anti-reverse rotating shaft from generating a rotational inertia that propels it forward in the driving direction. By setting the first one-way rotating interceptor and the first ratchet on the anti-reverse rotating shaft and the raised block respectively, when the wheel enters, the anti-reverse rotating shaft contacts the wheel. The wheel drives the anti-reverse rotating shaft to rotate in the opposite direction, but because the first one-way rotating interceptor abuts against the first ratchet, mechanical interference is formed, and the anti-reverse rotating shaft is locked to the first one-way rotating interceptor, allowing the wheel to pass over the anti-reverse rotating shaft. When a wheel accidentally rolls backward, its movement is slow. The wheel contacts the anti-rollover axle. Due to the unidirectional motion of the ratchet, the anti-rollover axle rotates in the opposite direction of the wheel's rotation, causing the wheel to slip, similar to gear meshing. This prevents the wheel from rolling off the axle. At this point, the wheel requires more force to slide downhill, making it more difficult to return to the ground from the raised platform. Even when the wheel is about to pass the anti-rollover axle, the engagement of the axle causes it to retract in the opposite direction of its movement. The wheel's own weight further pulls it back, ensuring safety by preventing it from crossing the axle each time it attempts to do so. When the wheel needs to roll out normally, increasing its downhill speed prevents the anti-rollover axle from stopping it, allowing the wheel to roll over the axle. The locking process is entirely automated by the mechanical structure, requiring no manual intervention. If the wheel shows even the slightest tendency to slip, the locking mechanism is triggered instantly, with a reaction speed far exceeding that of a human. This provides passive and automatic safety protection, effectively preventing the wheel from slipping unexpectedly and offering good safety. Attached Figure Description

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] See Figures 1-3 An embodiment of the composite structure wheel riser block of the present invention includes a riser block body 1, an anti-reverse rotation shaft 2, and a first anti-reverse structure 3.

[0031] The booster block body 1 has an inclined section 11 and a booster section 12. The booster block body 1 serves as a support platform for raising and elevating the wheel, the inclined section 11 is used for the wheel to climb or descend slopes, and the booster section 12 provides a height platform for the wheel to rest on. The inclined section 11 and the booster section 12 are connected sequentially along the direction of wheel entry. The inclined section 11 and the booster section 12 together form a continuous support surface from the ground to a specified height. The wheel must make line contact with and drive over the inclined section 11 before reaching the booster section 12.

[0032] The anti-reverse rotation shaft 2 is hinged to the raised part 12 and located at the top of the raised part 12. The anti-reverse rotation shaft 2 forms the actual bearing surface of the top of the raised part 12, and unlike the fixed surface, the anti-reverse rotation shaft 2 can rotate.

[0033] The first anti-reverse structure 3 includes a first one-way rotating interceptor 31 and a first ratchet 32. One of the first one-way rotating interceptor 31 and the first ratchet 32 ​​is located on the raised block body 1, and the other is located on the anti-reverse rotating shaft 2. Obviously, the first one-way rotating interceptor 31 can be located on the raised block body 1, and the first ratchet 32 ​​can be located on the anti-reverse rotating shaft 2; alternatively, the first ratchet 32 ​​can be located on the raised block body 1, and the first one-way rotating interceptor 31 can be located on the anti-reverse rotating shaft 2; the former is more suitable. The first one-way rotating interceptor 31 abuts against the first ratchet 32 ​​to prevent the anti-reverse rotating shaft 2 from generating rotational inertia in the driving direction. It can be understood that after the first one-way rotating interceptor 31 abuts against the first ratchet 32, when the wheel moves forward in the driving direction, the first one-way rotating interceptor 31 and the first ratchet 32 ​​form mechanical interference, thereby preventing the first ratchet 32 ​​from rotating.

[0034] The working principle of the composite structure wheel riser block of the present invention is as follows: During use, the user places the riser block on a slope. The wheel drives into the slope from the inclined part 11 and the riser part 12 in sequence. Upon entry, the anti-reverse rotating shaft 2 contacts the wheel, causing the wheel to rotate in the opposite direction. However, due to the contact between the first one-way rotation interceptor 31 and the first ratchet 32, mechanical interference is formed, locking the anti-reverse rotating shaft 2 and the first one-way rotation interceptor 31, allowing the wheel to pass over the anti-reverse rotating shaft 2. If the wheel accidentally reverses, its movement speed is slower, and the wheel contacts the anti-reverse rotating shaft 2. Due to the unidirectional movement of the ratchet, the anti-reverse rotating shaft 2 can rotate in the opposite direction of the wheel's rotation, thus making the wheel and the anti-reverse rotating shaft 2 similar. The meshing of gears causes slippage, preventing the wheel from exiting the anti-rollover rotating shaft 2. At this point, the wheel needs more force to slide downhill, making it more difficult for the wheel to return to the ground from the raised part 12. Even when the wheel is about to pass the anti-rollover rotating shaft 2, the anti-rollover rotating shaft 2 "meets" with the wheel, causing the wheel to retract in the opposite direction of the wheel's movement. Furthermore, due to the wheel's own weight, the wheel is retracted, ensuring safety by retracting the wheel whenever it is about to pass the anti-rollover rotating shaft 2. When the wheel needs to exit normally, by increasing the downhill speed of the wheel, the rotation of the anti-rollover rotating shaft 2 can no longer prevent the wheel from sliding downhill, allowing the wheel to pass the anti-rollover rotating shaft 2 and exit.

[0035] The raised block body 1 has an inclined portion 11 and a raised portion 12, which are connected sequentially along the wheel's driving direction. The inclined portion 11 is used for the wheel to climb or descend slopes. The raised portion 12 structure allows the wheel to rise to the required height smoothly and effortlessly, avoiding severe impact between the wheel and the edge of the raised block, thus protecting the tire and making operation smoother. The raised portion 12 provides a stable horizontal parking platform for the raised wheel, ensuring the vehicle's center of gravity is stable in the raised state, facilitating tire changing, inspection, and other operations. The sequential connection of the two along the wheel's driving direction enforces the spatial order of inclined portion 11 in front and raised portion 12 behind, providing the necessary prerequisite for the correct triggering and effectiveness of the subsequent anti-rollover function.

[0036] The anti-skid rotating shaft 2 is hinged to the raised part 12 and located on top of the raised part 12. Traditional raised blocks rely on static friction between the tire and the surface of the fixed block for anti-skid performance, which is unreliable. The anti-skid rotating shaft 2 can control the difficulty of the wheel passing through by rotating.

[0037] The first anti-reverse structure 3 includes a first one-way rotating interceptor 31 and a first ratchet 32. One of the first one-way rotating interceptor 31 and the first ratchet 32 ​​is located on the raised block body 1, and the other is located on the anti-reverse rotating shaft 2. The first one-way rotating interceptor 31 abuts against the first ratchet 32 ​​to prevent the anti-reverse rotating shaft 2 from generating a rotational inertia in the driving direction. By setting the first one-way rotating interceptor 31 and the first ratchet 32 ​​on the anti-reverse rotating shaft 2 and the raised block respectively, when the wheel drives in, the anti-reverse rotating shaft 2 contacts the wheel. The wheel drives the anti-reverse rotating shaft 2 to rotate in the opposite direction. However, because the first one-way rotating interceptor 31 abuts against the first ratchet 32, mechanical interference is formed, and the anti-reverse rotating shaft 2 is locked with the first one-way rotating interceptor 31, allowing the wheel to pass over the anti-reverse rotating shaft 2. When a wheel accidentally reverses, its movement speed is slow. The wheel contacts the anti-reverse rotating shaft 2. Due to the unidirectional motion of the ratchet, the anti-reverse rotating shaft 2 can rotate in the opposite direction of the wheel's rotation, causing the wheel to slip, similar to gear meshing, thus preventing the wheel from exiting the anti-reverse rotating shaft 2. At this point, the wheel requires greater force to slide downhill, making it more difficult for the wheel to return to the ground from the raised section 12. Even when the wheel is about to pass the anti-reverse rotating shaft 2, because the anti-reverse rotating shaft 2 is "engaged" with the wheel, it causes the wheel to retract in the opposite direction of the wheel's movement. Furthermore, due to its own weight, the wheel is pulled back, ensuring safety whenever it tries to pass the anti-reverse rotating shaft 2. When the wheel needs to exit normally, by increasing the downhill speed of the wheel, the rotation of the anti-reverse rotating shaft 2 can no longer prevent the wheel from sliding downhill, allowing the wheel to pass the anti-reverse rotating shaft 2 and exit. The locking process is entirely automated by the mechanical structure, requiring no manual intervention. If the wheel shows even the slightest tendency to slip, the locking mechanism is triggered instantly, with a reaction speed far exceeding that of a human. This provides passive and automatic safety protection, effectively preventing the wheel from slipping unexpectedly and offering good safety.

[0038] Preferably, the first ratchet 32 ​​is sleeved on the anti-reverse rotation shaft 2 and rotates with the anti-reverse rotation shaft 2; the hinged end of the first one-way rotation intercepting rod 31 is hinged to the raised block body 1, and the swinging end of the first one-way rotation intercepting rod 31 abuts against the first ratchet 32; the raised block body 1 has a first support block 4, which is located on the swinging trajectory of the first one-way rotation intercepting rod 31 and is used to assist the first support block 4 in preventing the first ratchet 32 ​​from rotating. Obviously, compared with the first ratchet 32 ​​being set on the raised block body 1, the first one-way rotation intercepting rod 31 being set on the anti-reverse rotation shaft 2, in the former, the reaction force that prevents rotation is directly and without loss transmitted to the solid raised block body 1 through the hinge point of the intercepting rod. The force transmission path is more direct and efficient, which is more conducive to setting the first support block 4. When subjected to a huge impact, while the intercepting rod is jamming the ratchet teeth, its rod body will press tightly against the first support block 4. At this point, the impact force is converted into pressure on the interceptor bar, which is shared by the support block and the main body, rather than solely by the hinge pin of the interceptor bar bearing the shear force. This significantly enhances the structure's rigidity and overload resistance, preventing the hinge point from shearing or the interceptor bar from bending. The latter, where the interceptor bar jams the fixing ratchet during locking, would apply a huge reverse torque to the rotating shaft, potentially damaging the device.

[0039] Preferably, the raised block body 1 further includes a travel limiting part 13. The inclined part 11 and the raised part 12 are connected sequentially along the wheel and the travel limiting part 13 is connected along the wheel's driving direction. The top height of the travel limiting part 13 is greater than the height of the raised part 12, and it is used to prevent the wheel from leaving the raised part 12 along the driving direction. The height difference forms a stepped barrier, preventing the wheel from rushing directly out of the raised part 12 along the driving direction due to inertia or operational errors, thus solving the safety hazard of the wheel crossing the raised block. The limiting part can serve as an end point marker for the wheel, ensuring that the wheel stops stably at the designated position on the raised part 12, facilitating subsequent maintenance, fixing, and other operations, and improving the accuracy of use.

[0040] Preferably, the composite structure wheel riser further includes a second anti-reverse structure 5, which includes a second one-way rotating interceptor 51, a second ratchet 52, and a push-pull rod 53. One of the second one-way rotating interceptor 51 and the second ratchet 52 is disposed on the riser body 1, and the other is disposed on the anti-reverse rotating shaft 2. The second one-way rotating interceptor 51 abuts against the second ratchet 52 to prevent the anti-reverse rotating shaft 2 from generating a rotational inertia close to the inclined portion 11. The push-pull rod 53 connects the second one-way rotating interceptor 51 or the second ratchet 52 and is movably inserted into the riser body 1 so that the second one-way rotating interceptor 51 and the second ratchet 52 can translate relative to each other along the axial direction of the second one-way rotating interceptor 51, thereby causing the second one-way rotating interceptor 51 and the second ratchet 52 to abut against each other or disengage from each other. The first anti-reverse mechanism is used to prevent the wheel from reversing, while the second anti-reverse mechanism controls the wheel to reverse, solving the problem of the wheel being difficult to back out after the vehicle has been repaired. The second anti-reverse mechanism is locked by the push-pull rod 53. When the wheel needs to be prevented from reversing, the push-pull rod 53 is pushed to move the second one-way rotating interceptor rod 51 away from the second ratchet 52, and the anti-reverse rotating shaft 2 can rotate to achieve the anti-reverse function. When the wheel needs to drive out, the push-pull rod 53 is pushed to make the second one-way rotating interceptor rod 51 and the second ratchet 52 abut against each other, and the anti-reverse rotating shaft 2 stops, so that the wheel can drive out even if the speed is slow.

[0041] Preferably, the raised block body 1 is provided with a second support block 6. The second support block 6 is located on the swing trajectory of the second unidirectional rotating interceptor bar 51 and is used to assist the second support block 6 in preventing the first ratchet 32 ​​from rotating. The second support block 6 has the same function as the first support block 4. The second support block 6 provides force support for the second interceptor bar to cope with the impact force when the wheel moves forward, avoid the second interceptor bar from breaking or failing, and ensure the dual reliability of bidirectional backlash prevention. The first and second support blocks 6 correspond to the front and rear backlash prevention structures, respectively, so that the force distribution of the raised block in the front and rear directions is uniform, reducing local deformation of the body and extending the service life.

[0042] Preferably, the raised portion 12 has a mounting groove 121, the opening of which is recessed downwards from the top of the raised portion 12. The anti-reverse rotating shaft 2 is mounted in the mounting groove 121, the top of which extends out from the inside of the groove along the opening. The mounting groove 121 provides an embedded mounting space for the rotating shaft, preventing the shaft from shifting due to lateral impact. Simultaneously, the groove can shield the lower part of the shaft, reducing the entry of dust and debris and lowering rotational resistance. The rotating shaft is higher than the groove opening, ensuring that when the wheel rolls onto the raised portion 12, it can directly contact the shaft, driving the shaft to rotate and preventing the wheel from spinning freely without the shaft rotating, which would lead to anti-reverse failure. The speed bump 7 is located in front of the shaft. The wheel first passes through the speed bump 7 for buffering and deceleration before contacting the rotating shaft, reducing the instantaneous impact of the wheel on the shaft, reducing shaft wear, and improving the stability of the vehicle when driving onto the raised portion. Bearing 8 provides a standardized, robust support point, enabling a more even and efficient transfer of wheel weight and impact loads to the shim body 1, avoiding rapid wear caused by direct friction between the rotating shaft and the body's bore. The relative arrangement means that bearing 8 is positioned to withstand axial and radial loads effectively (typically at both ends of the shaft), ensuring the stability of the rotating shaft support and extending its lifespan under high loads and frequent use.

[0043] Preferably, the anti-reverse rotating shaft 2 is fitted with a bearing 8, which is mounted on the raised portion 12. The core function of the bearing 8 (whether a rolling bearing 8 or a sliding bearing 8) is to reduce the frictional resistance between the rotating shaft and the raised block body 1. This makes it easier for the rotating shaft to rotate when the wheel is on it.

[0044] Preferably, the composite wheel jack further includes at least two side baffles 9, which are installed above and supported by the jacking portion 12. The side baffles 9 extend along the horizontal direction of the two jacking portions 12, and are positioned opposite each other on opposite horizontal sides of the jacking portion 12. The baffles form side barriers, restricting lateral displacement of the wheels. Even if the vehicle's entry angle is slightly off, or the wheels shift laterally due to road inclination, the baffles will prevent them from slipping off the side of the jacking block, improving safety. The baffles extend along the entry direction, guiding the wheels along the center of the jacking portion 12, helping the driver quickly align with the jacking block and reducing entry difficulty, especially suitable for novice drivers or in situations with poor visibility. The baffles are directly supported by the jacking portion 12, forming an integrated structure with the main body, making them less prone to loosening or falling off under stress, and adaptable to the lateral impact force of heavy-duty vehicles.

[0045] Preferably, the side baffle 9 is provided with drainage holes 10, which extend axially along the rotation axis; multiple drainage holes 10 are provided, extending along the length of the raised block body 1. During outdoor use, rainwater and car wash water can be quickly discharged through the drainage holes 10, preventing water accumulation in the raised part 12 and the inside of the baffle, thus preventing wheels from slipping due to water accumulation and improving safety in wet environments. The drainage holes 10 have a hollow design, which reduces the overall weight of the raised block, facilitating handling and movement. Simultaneously, the holes are evenly distributed along the length direction, without affecting the structural strength and protective performance of the baffle. Mud, sand, gravel, and other debris can be discharged through the drainage holes 10, preventing accumulation on the inside of the baffle, reducing interference with the rotation axis and anti-reverse structure, and ensuring the normal operation of the mechanism.

[0046] Preferably, EP300 canvas is layered to form the raised block body 1; alternatively, 4 layers of steel mesh and 2 layers of 2000 DPP aramid canvas are used, with the remainder being EP300 canvas. The EP300 canvas is layered, and the 4 layers of steel mesh and 2 layers of 2000 DPP aramid canvas are evenly distributed within the canvas layers to form the raised block body 1. The EP300 canvas, steel mesh, and aramid canvas are all high-toughness, high-wear-resistant materials. Their layered structure forms a composite reinforcement structure that can withstand long-term pressure from heavy vehicles (such as trucks and construction vehicles), and is not easily deformed, cracked, or broken, far exceeding the load-bearing capacity of ordinary rubber and plastic raised blocks. The composite structure of canvas and steel mesh combines rigidity and elasticity, slightly cushioning vibrations when vehicles drive over it, reducing impact on the vehicle chassis and the raised block body 1, improving user comfort and extending the lifespan of the block. Aramid canvas and EP300 canvas have excellent weather resistance and anti-aging properties. They can be used for a long time in outdoor sun, rain, and high and low temperature environments without becoming brittle or degrading, ensuring structural stability.
