Description

Technical Field

[0001] This utility model relates to the technical field of tricycle accessories, specifically a shock-absorbing mud tile for tricycles. Background Technology

[0002] As a common short-distance transportation and mobility tool, the mudguards on tricycles are important body parts, mainly used to block mud and water splashed from the wheels, ensuring a clean riding environment and the rider's safety.

[0003] In existing technologies, tricycle mudguards mostly adopt a one-piece structure, typically made of plastic or iron. While plastic mudguards are cheaper and lighter, their inherent toughness is insufficient, making them prone to breakage, falling off, or damage during vehicle operation, especially on bumpy roads or after minor collisions, resulting in a short lifespan. Iron mudguards offer improved strength compared to plastic mudguards; however, their one-piece design means that when the vehicle resonates during operation, the mudguard can come into direct, rigid contact with the frame, leading to breakage, noticeable rattles, and significant noise, severely impacting riding comfort. Furthermore, prolonged vibration can cause the mudguard's fasteners to loosen, further increasing the risk of rattles and structural damage, resulting in a poor user experience. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of existing tricycle mudplates, such as easy breakage and loud noise, and to provide a shockproof mudplate for tricycles.

[0005] A shock-absorbing mudguard for a tricycle includes a mudguard, a bracket, and a fixed support frame. One end of the bracket is connected to the mudguard, and the other end of the bracket is connected to the fixed support frame. The fixed support frame is used to install on the half-shaft of the tricycle or the rear half of the vehicle. The mudguard and the bracket, as well as the bracket and the fixed support frame, are fixed by screws, spring washers, and rubber pads. A buffer sleeve is also provided at the connection between the bracket and the fixed support frame.

[0006] Furthermore, the number of supports is several, and the several supports are distributed between the mudguard and the fixed support frame.

[0007] Furthermore, the rubber pad is disposed between the contact surfaces of the two connected components, and the spring pad is sleeved on the screw shank and located between the screw nut and the outer surface of the component.

[0008] Furthermore, the buffer sleeve is a hollow cylindrical elastic material component, which is inserted into the positioning hole of the bracket and the fixed support frame. The screw passes through the inside of the buffer sleeve, so that the bracket and the fixed support frame are in indirect contact, and the screw is in indirect contact with the bracket and the fixed support frame.

[0009] When a tricycle travels on a bumpy road, the vehicle body resonates and vibrates. This vibration is first transmitted to the fixed support frame fixed to the half-shaft or the rear half of the vehicle. Because hollow cylindrical buffer sleeves are inserted into the positioning holes of the fixed support frame and the bracket, and the screws pass through the inside of the buffer sleeves, the fixed support frame and the bracket, as well as the screws and both, are in indirect contact. The buffer sleeves can perform the first step of buffering and absorbing the transmitted vibration, weakening the intensity of the vibration transmission. At the same time, rubber pads and spring pads are equipped at the screw connections between the bracket and the mudguard and various components. The rubber pads have good elastic deformation capabilities, which can further buffer the vibration, while the spring pads can effectively offset the impact force brought by the vibration and prevent the screws from loosening due to long-term vibration. The multi-stage damping structure works together to significantly reduce the transmission efficiency of vibration between the mudguard components, thereby avoiding abnormal noise and rattles caused by rigid contact between components, and also reducing the damage of vibration to the mudguard structure.

[0010] Beneficial effects Through a split-structure design, combined with a multi-stage shock absorption structure consisting of a buffer sleeve, rubber pads, and spring pads, direct rigid contact between components is avoided, greatly reducing mud vibration caused by whole-vehicle resonance, effectively eliminating abnormal noise and squeaks caused by mud vibration, and improving riding comfort.

[0011] The multi-stage shock absorption structure not only reduces the impact of vibration on the tile body, but also avoids the problem of loose screws or rivets caused by long-term vibration, reducing the probability of tile breakage and falling off, and significantly extending the overall service life of the tile.

Detailed Implementation

[0013] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] like Figure 1-4 As shown; A type of shock-absorbing mud for tricycles.

[0015] This implementation plan addresses the technical problems existing in the prior art, as disclosed in the background section above: "In the prior art, tricycle mudguards mostly adopt an integral structure, usually made of plastic or iron. While plastic mudguards are lower in cost and lighter in weight, their inherent toughness is insufficient. During vehicle operation, they are prone to breakage, falling off, or damage when encountering bumpy roads or minor collisions, resulting in a short service life. Iron mudguards have higher strength than plastic mudguards; however, their integral structural design means that when the vehicle resonates during operation, the mudguards are prone to direct rigid contact with the vehicle frame, easily leading to breakage and generating noticeable abnormal noise and loud noise, severely affecting riding comfort. Furthermore, long-term vibration can cause the mudguard's fixing connections to loosen, further exacerbating the risk of abnormal noise and structural damage, resulting in a poor user experience." In practical terms, this problem is clearly real and difficult to solve. Therefore, to address this technical problem, a shock-absorbing mudguard for tricycles is provided.

[0016] Implementation Case 1 like Figure 1-4 As shown in the figure; This utility model provides a shockproof mudguard for a tricycle. Its specific structure includes a mudguard 1, a bracket 2, and a fixed support frame 3. The number of brackets 2 is several. One end of the brackets 2 is connected to the mudguard 1, and the other end is connected to the fixed support frame 3. The fixed support frame 3 is fixedly installed on the half axle of the tricycle or the rear half of the vehicle.

[0017] In the connection structure of each component, the connection between the mudguard 1 and the bracket 2 abandons the traditional rivet connection and uses screws 4 with spring washers 5 and rubber pads 6 for fixation. The rubber pads 6 are placed between the contact surfaces of the mudguard 1 and the bracket 2, and the spring washers 5 are sleeved on the screw 4 and located between the nut of the screw 4 and the outer surface of the bracket 2. The elastic deformation of the rubber pads 6 buffers the vibration between the two, and the elastic properties of the spring pads 5 prevent the screws 4 from loosening due to vibration. At the connection between the bracket 2 and the fixed support frame 3, a hollow cylindrical buffer sleeve 7 is provided. The buffer sleeve 7 is inserted into the positioning holes of the bracket 2 and the fixed support frame 3. The screws 4 pass through the inside of the buffer sleeve 7, so that the bracket 2 and the fixed support frame 3 are indirectly in contact, and the screws 4 are also indirectly in contact with the bracket 2 and the fixed support frame 3, avoiding direct rigid collision between iron and iron. At the same time, this connection is also reinforced with screws 4 with spring washers 5 and rubber pads 6, further improving the stability of the connection and the shock absorption effect.

[0018] During actual assembly, first, the fixed support frame 3 is securely installed on the half axle of the tricycle or the preset installation position of the rear half of the vehicle. Then, the hollow cylindrical buffer sleeve 7 is inserted into the positioning hole corresponding to the bracket 2 and the fixed support frame 3. Then, the screw 4 is passed through the inside of the buffer sleeve 7, and the bracket 2 and the fixed support frame 3 are fixed together with the spring washer 5 and the rubber washer 6. After that, the other end of the bracket 2 is aligned with the preset connection point of the mudguard 1. The mudguard 1 and the bracket 2 are fixed together by the combination of screw 4, spring washer 5 and rubber washer 6. Thus, the assembly of the entire mudguard is completed.

[0019] When the tricycle is in motion, the vibration generated by the vehicle body is transmitted to the fixed support frame 3. It is first absorbed and buffered by the hollow cylindrical buffer sleeve 7 inserted into the positioning hole. Since the screw 4 passes through the inside of the buffer sleeve 7, direct contact between the screw and the bracket 2 and the fixed support frame 3 is avoided, further blocking the vibration transmission path and greatly reducing the transmission of vibration to the bracket 2. Then, the vibration on the bracket 2 is further buffered and weakened by the rubber pad 6 and spring pad 5 at the connection between the mudguard 1 and the bracket 2 during the transmission process. At the same time, the spring pad 5 at each connection point can effectively prevent the screw 4 from loosening due to long-term vibration, thereby achieving shock absorption protection for the entire mudguard, avoiding abnormal noise caused by rigid contact between components, and reducing the damage of vibration to the mudguard structure.

[0020] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
