Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, and in particular to a limiting mechanism and a vehicle. Background Technology

[0002] Commercial vehicles such as trucks or vans use leaf springs in their suspension systems. Leaf springs absorb the impact of uneven road surfaces through elastic deformation, thereby ensuring the vehicle's driving stability.

[0003] Because the elastic deformation range of leaf springs is limited, in order to prevent excessive suspension travel during vehicle operation, especially when encountering large bumps, which could cause the leaf springs to jump upwards and collide rigidly with the vehicle frame, it is usually necessary to install rubber limit blocks on the leaf springs. When the vehicle is driving on uneven roads, the suspension will be subjected to large impact loads. The rubber limit blocks can absorb these impact energies, reduce the feeling of bumps in the vehicle, and thus improve the driving comfort of the vehicle.

[0004] However, the limit blocks made of rubber are prone to aging in the natural environment and are easily cracked and deformed under impact, resulting in poor effectiveness of the limit blocks in limiting the suspension travel. Utility Model Content

[0005] This application provides a limiting mechanism and a vehicle to solve the technical problem that the limiting blocks made of rubber materials in related technologies are prone to cracking and deformation, which leads to the limiting blocks being unable to limit the suspension travel.

[0006] In a first aspect, embodiments of this application provide a limiting mechanism, including:

[0007] A first magnetic element, the first magnetic element being used to be mounted on the vehicle's suspension;

[0008] The second magnetic component is used to be disposed on the vehicle frame. The first magnetic component and the second magnetic component are disposed opposite to each other, and the first magnetic component and the second magnetic component are magnetically repelled.

[0009] An isolating element is disposed on at least one of the first magnetic element and the second magnetic element, the isolating element being used to prevent the first magnetic element and the second magnetic element from directly contacting each other.

[0010] In some embodiments, the first magnetic element includes a first base and a first magnetic part, the first base being detachably connected to the suspension, and the first magnetic part being disposed on the first base.

[0011] In some embodiments, the system further includes an arc-shaped rod and a first connector, wherein the arc-shaped rod has a notch for the first base and the suspension to be moved into, and the first connector is used to fix or detach the arc-shaped rod from the suspension to detachably connect the first base to the suspension.

[0012] In some embodiments, the second magnetic element includes a second base and a second magnetic portion, the second base being detachably connected to the vehicle frame, and the second magnetic portion being disposed on the second base.

[0013] In some embodiments, a second connector is further included, which is configured to pass through or detach from the second base and the frame to detachably connect the first base to the frame.

[0014] In some embodiments, the first magnetic part and the second magnetic part are at least one of a permanent magnet and an electromagnet.

[0015] In some embodiments, an adjustment member is further included, the adjustment member being disposed on the vehicle, the adjustment member being used to adjust the magnetic force of the first magnetic member and the second magnetic member.

[0016] In some embodiments, the insulating element comprises a rubber block.

[0017] In some embodiments, the rubber block is provided on both the first magnetic element and the second magnetic element, and the opposing surfaces of the rubber blocks of the first magnetic element and the second magnetic element are set as arc-shaped surfaces, with the arc-shaped surfaces on both sides extending in a direction that approaches each other.

[0018] Secondly, embodiments of this application provide a vehicle, including a vehicle body and the limiting mechanism disposed on the vehicle body.

[0019] This application provides a limiting mechanism and a vehicle. The limiting mechanism, by employing a first magnetic component and a second magnetic component, allows the suspension to bring the first magnetic component closer to the second magnetic component on the vehicle frame during vehicle operation. At this time, the first and second magnetic components repel each other magnetically, preventing the suspension from approaching the frame in a non-contact manner. This prevents direct contact between the first and second magnetic components, thus avoiding damage and failure, and effectively limiting the suspension's travel. When the vehicle encounters significant bumps during operation, causing excessive suspension travel, an isolating component prevents direct contact between the first and second magnetic components, protecting them from damage due to continuous contact under extreme conditions. This indirectly extends the service life of the first and second magnetic components, further effectively limiting the suspension's travel. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0034] Commercial vehicles typically use leaf springs as their suspension system. However, the elastic deformation range of leaf springs is relatively limited. This means that during vehicle operation, especially when encountering large bumps or uneven road surfaces, the suspension travel may exceed the elastic range of the leaf springs. If the suspension travel is not limited, the leaf springs may bounce excessively and collide rigidly with the chassis. Such collisions not only generate significant noise but may also damage the chassis, leaf springs, or other suspension components, severely impacting vehicle safety and comfort. To prevent this, rubber limiters are usually installed on the leaf springs. When the vehicle travels on uneven roads, the suspension is subjected to significant impact loads. The rubber limiters absorb this impact energy, effectively buffering the collision between the axle and the chassis, thereby reducing the feeling of bumps and improving vehicle ride comfort.

[0035] Although rubber suspension blocks play a vital role in improving vehicle comfort and safety, rubber materials are susceptible to aging due to environmental factors. Prolonged exposure to sunlight, air, and humidity causes rubber to harden and become brittle, losing its original elasticity and toughness. Furthermore, during vehicle operation, the suspension blocks are frequently subjected to impacts. These repeated impacts can cause micro-cracks to form within the rubber material, which gradually expand, eventually leading to cracking or deformation. Once the suspension blocks crack or deform, their cushioning and limiting functions are significantly reduced, or even completely fail. This results in ineffective control of suspension travel, potentially leading to another rigid collision between the axle and the frame. This not only damages structural components but also reduces vehicle stability, lowers comfort, and may even create safety hazards.

[0036] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0037] Combination Figure 1 and Figure 2 This application provides a limiting mechanism, including:

[0038] The first magnetic element 100 is used to be installed on the suspension 700 of the vehicle.

[0039] The second magnetic component 200 is used to be installed on the vehicle frame 800. The first magnetic component 100 and the second magnetic component 200 are arranged opposite to each other, and the first magnetic component 100 and the second magnetic component 200 are magnetically repelled.

[0040] An isolating member 300 is disposed on at least one of the first magnetic member 100 and the second magnetic member 200, and the isolating member 300 is used to prevent the first magnetic member 100 and the second magnetic member 200 from directly contacting each other.

[0041] In this embodiment, multiple sets of the first magnetic element 100 and the second magnetic element 200 are provided. For example, four sets of the first magnetic element 100 and the second magnetic element 200 can be provided. The four sets of the first magnetic element 100 and the second magnetic element 200 can be evenly distributed on the suspension 700 and the frame 800, so that multiple sets of the first magnetic element 100 and the second magnetic element 200 can further prevent the suspension 700 and the frame 800 from directly contacting each other. In other embodiments, the number of the first magnetic element 100 and the second magnetic element 200 can be adaptively adjusted as needed.

[0042] In this embodiment, both the first magnetic component 100 and the second magnetic component 200 are provided with an isolating component 300, and the isolating component 300 is disposed on the opposite surfaces of the first magnetic component 100 and the second magnetic component 200. When the suspension 700 approaches the vehicle frame 800, the first magnetic component 100 can drive the isolating component 300 to abut against the isolating component 300 on the second magnetic component 200, thereby preventing the first magnetic component 100 and the second magnetic component 200 from directly abutting against each other.

[0043] In other embodiments, the insulating member 300 may be provided separately on the first magnetic member 100 or the second magnetic member 200, so that the first magnetic member 100 or the second magnetic member 200 abuts against the insulating member 300, thereby preventing the first magnetic member 100 and the second magnetic member 200 from directly abutting against each other.

[0044] In this application, by employing a first magnetic element 100 and a second magnetic element 200, when the vehicle is in motion, the suspension 700 can bring the first magnetic element 100 closer to the second magnetic element 200 on the frame 800. At this time, the first magnetic element 100 and the second magnetic element 200 repel each other magnetically, preventing the suspension 700 from approaching the frame 800 in a non-contact manner. This prevents the first magnetic element 100 and the second magnetic element 200 from directly contacting each other and causing damage or failure, thereby effectively limiting the travel of the suspension 700. When the vehicle is in motion... When encountering significant bumps during the process, causing excessive travel of the suspension 700, the isolation component 300 prevents the first magnetic component 100 and the second magnetic component 200 from directly contacting each other. This protects the first magnetic component 100 and the second magnetic component 200, preventing them from being damaged by continuous contact under extreme conditions. This indirectly extends the service life of the first magnetic component 100 and the second magnetic component 200, thereby further effectively limiting the travel of the suspension 700.

[0045] The first magnetic component 100 includes a first base 110 and a first magnetic part 120. The first base 110 is used for detachable connection with the suspension 700, and the first magnetic part 120 is disposed on the first base 110.

[0046] In this embodiment, the first base 110 is rectangular, and the first magnetic part 120 has a rectangular cross-section. The first magnetic part 120 can be integrally mounted on the first base 110, or it can be mounted on the first base 110 by welding, pasting, or snapping. The area of ​​the rectangular first magnetic part 120 is smaller than the area of ​​the rectangular first base 110. There is a gap between the four edges of the first magnetic part 120 and the four edges of the first base 110, so that the larger base can provide better support for the first magnetic part 120.

[0047] In this embodiment, the first magnetic part 120 is generally rectangular; in other embodiments, the shape of the first magnetic part 120 can be adapted as needed, for example, the first magnetic part 120 can be set as a cylinder.

[0048] In other embodiments, the shapes of the first base 110 and the first magnetic part 120 can be adapted as needed. For example, both the first base 110 and the first magnetic part 120 can be set to be circular, and the diameter of the circular first magnetic part 120 can be smaller than the diameter of the circular first base 110.

[0049] In this embodiment, by adopting the first base 110 and the first magnetic part 120, the first base 110 can support the first magnetic part 120, thereby indirectly improving the fixing strength of the first magnetic part 120 on the suspension 700. By detachably connecting the first base 110 to the suspension 700, it is convenient to install and remove the first base 110, thereby facilitating the maintenance and replacement of the first magnetic part 120.

[0050] The limiting mechanism also includes an arc-shaped rod 400 and a first connector 500. The notch of the arc-shaped rod 400 is used for the first base 110 and the suspension 700 to move in. The first connector 500 is used to fix or detach the arc-shaped rod 400 from the suspension 700 so that the first base 110 and the suspension 700 can be detachably connected.

[0051] In this embodiment, both ends of the arc-shaped rod 400 are provided with threaded portions, the first connecting piece 500 is a nut, and there are two arc-shaped rods 400. The two arc-shaped rods 400 are respectively provided on both sides of the first base 110, and each arc-shaped rod 400 has a nut sleeved and threadedly connected to the threaded portion at both ends.

[0052] In this application, when it is necessary to fix the first base 110 to the suspension 700, the first base 110 is placed on the suspension 700, and the arc rod 400 is moved toward the first base 110 and the suspension 700, so that the first base 110 and the suspension 700 move into the recess of the arc rod 400. At this time, the nut is sleeved on the end of the arc rod 400, and the nut is turned on the threaded part, so that the nut abuts against the side of the suspension 700 away from the first base 110, thereby abutting the inner wall of the recess of the arc rod 400 against the first base 110, and abutting the first base 110 against the suspension 700, thereby fixing the first base 110 to the suspension 700, which improves the fixing strength of fixing the first base 110 to the suspension 700.

[0053] In other embodiments, the first base 110 may be fixed to the suspension 700 by means of bolting, bonding, welding, snap-fitting or riveting.

[0054] In other embodiments, grooves may be provided on the first base 110 and on both sides of the first base 110, thereby preventing the arc rod 400 from moving on the first base 110 by moving the arc rod 400 into the groove.

[0055] The second magnetic component 200 includes a second base 210 and a second magnetic part 220. The second base 210 is used for detachable connection with the frame 800, and the second magnetic part 220 is disposed on the second base 210.

[0056] In this embodiment, the second base 210 is rectangular, and the cross-section of the second magnetic part 220 is also rectangular. The second magnetic part 220 can be integrally mounted on the second base 210, or it can be mounted on the second base 210 by welding, pasting, or snapping. The area of ​​the rectangular second magnetic part 220 is smaller than the area of ​​the rectangular second base 210. There is a gap between the four edges of the second magnetic part 220 and the four edges of the second base 210, so that the larger base can provide better support for the second magnetic part 220.

[0057] In this embodiment, the second magnetic part 220 is generally rectangular; in other embodiments, the shape of the second magnetic part 220 can be adapted as needed, for example, the second magnetic part 220 can be set as a cylinder; the first magnetic part 120 and the second magnetic part 220 can also be set with different shapes, for example, the first magnetic part 120 can be set as concave and the second magnetic part 220 can be set as convex, so that the protrusion of the convex second magnetic part 220 can move toward the concave first magnetic part 120, thereby extending the moving distance of the first magnetic part 120 and the second magnetic part 220 and preventing the first magnetic part 120 and the second magnetic part 220 from directly contacting each other.

[0058] In other embodiments, the shapes of the second base 210 and the second magnetic part 220 can be adapted as needed. For example, both the second base 210 and the second magnetic part 220 can be set to be circular, and the diameter of the circular second magnetic part 220 can be smaller than the diameter of the circular second base 210.

[0059] In this embodiment, by adopting the second base 210 and the second magnetic part 220, the second base 210 can support the second magnetic part 220, thereby indirectly improving the fixing strength of the second magnetic part 220 on the frame 800. By detachably connecting the second base 210 to the frame 800, it is convenient to install and remove the second base 210, thereby facilitating the maintenance and replacement of the second magnetic part 220.

[0060] The limiting mechanism also includes a second connector 600, which is used to pass through or detach from the second base 210 and the frame 800 to detachably connect the first base 110 to the frame 800.

[0061] In this embodiment, the second connector 600 is a rivet; in other embodiments, the second connector 600 can also be replaced by a bolt or a clip, so that the second base 210 can be bolted or snapped to the frame 800, or the second base 210 can be fixed to the frame 800 by welding or bonding.

[0062] In this application, by adopting a riveted connection, a strong and reliable connection can be formed between the second base 210 and the frame 800, thereby providing high tensile and shear strength. Even in harsh working environments (such as humidity, high temperature, vibration, etc.), it can maintain stable performance and ensure long-term safety. The riveted connection is relatively simple and quick to operate, usually only requiring drilling, inserting rivets, and riveting with a rivet gun, which is suitable for on-site installation and maintenance, significantly reducing labor costs. The riveted connection can also effectively reduce stress concentration. By evenly distributing the load through multiple rivets, it avoids structural damage caused by local overload. At the same time, it absorbs the vibration energy of the vehicle during driving to a certain extent, reduces rigid collisions, reduces vibration and noise, and improves the comfort of operators.

[0063] The first magnetic part 120 and the second magnetic part 220 are at least one of a permanent magnet and an electromagnet.

[0064] In this embodiment, both the first magnetic part 120 and the second magnetic part 220 are permanent magnets; in other embodiments, both the first magnetic part 120 and the second magnetic part 220 can be electromagnets, or the first magnetic part 120 can be a permanent magnet and the second magnetic part 220 can be an electromagnet, or both the first magnetic part 120 and the second magnetic part 220 can be a combination of an electromagnet and a permanent magnet.

[0065] In this application, by employing permanent magnets, the magnetic field strength of the permanent magnets is stable and durable. Without the need for an external power source or a complex electromagnetic control system, it can provide a reliable repulsive force in a long-term stable manner, ensuring that the suspension 700 and the frame 800 always maintain a safe distance during driving and avoid rigid collisions. This non-contact repulsive force can effectively reduce mechanical wear and noise, significantly improving the driving comfort and quietness of the vehicle. The design structure of the permanent magnet is simple and easy to install, without adding additional mechanical complexity or maintenance costs. At the same time, its lightweight characteristics also help to reduce the overall weight of the vehicle.

[0066] The limiting mechanism also includes an adjusting member, which is installed on the vehicle and is used to adjust the magnetic force of the first magnetic member 100 and the second magnetic member 200.

[0067] In this embodiment, when both the first magnetic part 120 and the second magnetic part 220 are electromagnets, the magnetic force of the first magnetic part 120 and the second magnetic part 220 is adjusted by an adjusting member. The adjusting member includes a distance sensor, an adjustable resistor, and a controller. The distance sensor is disposed on the first base 110 and is used to detect the distance between the first base 110 and the second base 210. For example, when the vehicle is driving normally or encountering large bumps that cause the suspension 700 to bounce excessively, the distance sensor detects the distance between the first base 110 and the second base 210. If the distance between the first base 110 and the second base 210 is too close, it may cause the first magnetic part 120 and the second magnetic part 220 to directly contact each other. The current of the electromagnet coil can be controlled by the adjustable resistor and the electronic controller to increase the magnetic force of the electromagnet and prevent the first magnetic part 120 and the second magnetic part 220 from directly contacting each other. If the distance between the first base 110 and the second base 210 is too far, the magnetic force of the first magnetic part 120 and the second magnetic part 220 can be appropriately reduced to prevent the suspension 700 from being too stiff and affecting driving comfort.

[0068] In this application, by using an adjusting member to adjust the magnetic force of the first magnetic part 120 and the second magnetic part 220, the distance between the suspension 700 and the frame 800 can be dynamically adjusted according to different road conditions and load conditions, thereby optimizing the vehicle's driving performance. On bumpy roads, increasing the magnetic force can increase the distance, avoiding rigid collisions between the frame 800 and the suspension 700, and reducing noise and damage to components. On smooth roads or under high load conditions, decreasing the magnetic force can reduce the distance, improving the vehicle's stability and handling, and indirectly extending the service life of the first magnetic part 100 and the second magnetic part 200.

[0069] In other embodiments, the adjusting member can also be replaced by a driving member disposed on the suspension 700 and the chassis. The driving member can be a cylinder, an electric cylinder, or a hydraulic cylinder. By disposing the first base 110 and the second base 210 on the driving end of the driving member, the driving member drives the first base 110 and the second base 210 to move closer or further apart, thereby adjusting the initial distance between the first base 110 and the second base 210. When the initial distance between the first magnetic part 120 and the second magnetic part 220 is close, the repulsive force between the first magnetic part 120 and the second magnetic part 220 is large. When the initial distance between the first magnetic part 120 and the second magnetic part 220 is far, the repulsive force between the first magnetic part 120 and the second magnetic part 220 is small, thereby also achieving the adjustment of the magnetic force of the first magnetic part 120 and the second magnetic part 220.

[0070] The insulating element 300 includes a rubber block.

[0071] In this embodiment, the rubber block is bonded to the first magnetic part 120 and the second magnetic part 220 by vulcanization; in other embodiments, the rubber block may also be connected to the first magnetic part 120 and the second magnetic part 220 by bolts.

[0072] In this application, the rubber block can protect the first magnetic part 120 and the second magnetic part 220. When the vehicle is driving on a bumpy road and the suspension 700 has a large travel, the rubber block can effectively absorb the impact energy, prevent the permanent magnets from being damaged by rigid collisions, and extend the service life of the permanent magnets. The rubber block can also reduce the noise generated by direct contact between the permanent magnets, creating a quieter driving environment.

[0073] In other embodiments, the insulating member 300 can also be configured as a sleeve fitted over the first magnetic part 120 and the second magnetic part 220. By making the length of the sleeve greater than the height of the first magnetic part 120 and the second magnetic part 220, the sleeve can also prevent the first magnetic part 120 and the second magnetic part 220 from abutting. The insulating member 300 can also be replaced by a sponge provided on the first magnetic part 120 and the second magnetic part 220. Using a sponge can also achieve the protection of the first magnetic part 120 and the second magnetic part 220.

[0074] Rubber blocks are provided on both the first magnetic component 100 and the second magnetic component 200. The opposing surfaces of the rubber blocks of the first magnetic component 100 and the second magnetic component 200 are set as arc-shaped surfaces 310, and the two arc-shaped surfaces 310 extend toward each other.

[0075] In this embodiment, the rubber block is hemispherical, and the arc surface 310 is the spherical surface of the rubber block in a spherical state.

[0076] In this application, by employing an arc-shaped surface 310 and extending the two arc-shaped surfaces 310 toward each other, the height of the rubber block is increased. When the vehicle is traveling on a bumpy road and the suspension 700 has a large travel, when the two rubber blocks come into contact with each other, the arc-shaped surfaces 310 of the two rubber blocks can come into contact with each other, thereby increasing the degree of compression of the rubber block and preventing the compression of the rubber block from causing damage to the first magnetic part 120 and the second magnetic part 220, thus indirectly extending the service life of the first magnetic part 120 and the second magnetic part 220.

[0077] In other embodiments, the shape of the rubber block can be adaptively adjusted as needed, for example, the rubber block can be set to a wavy shape.

[0078] This application also provides a vehicle, including a vehicle body and a limiting mechanism of any of the above embodiments disposed on the vehicle body.

[0079] The specific structure of the limiting mechanism has been described in detail in the above embodiments and will not be repeated here.

[0080] In this embodiment, the vehicle is a commercial vehicle. In other embodiments, the vehicle may be replaced with a passenger car, or with a bicycle or other equipment that requires vibration damping.

[0081] The vehicle provided in this application, by setting a limiting mechanism, allows the suspension 700 to bring the first magnetic part 120 close to the second magnetic part 220 on the frame 800 during vehicle operation. At this time, the first magnetic part 120 and the second magnetic part 220 repel each other magnetically. By using permanent magnets, the magnetic field strength of the permanent magnets is stable and durable, requiring no external power supply or complex electromagnetic control system, and can provide a reliable repulsive force stably for a long time, ensuring that the suspension 700 and the frame 800 maintain a safe distance during operation and avoiding rigid collisions. This non-contact repulsive force can effectively reduce mechanical wear and noise, significantly improving the vehicle's performance. Driving comfort and quietness: When the vehicle encounters large bumps during driving, causing excessive travel of the suspension 700, the use of rubber blocks allows the first magnetic component 100 to engage with the rubber blocks on the second magnetic component 200, preventing direct contact between the first magnetic component 100 and the second magnetic component 200. This protects the first magnetic component 100 and the second magnetic component 200, preventing them from being damaged by continuous contact under extreme conditions. This indirectly extends the service life of the first magnetic component 100 and the second magnetic component 200, thereby further effectively limiting the travel of the suspension 700.

[0082] Finally, it should be noted that other embodiments of this utility model will readily occur to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This utility model is intended to cover any variations, uses, or adaptations of this utility model that follow the general principles of this utility model and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
