Description

Technical Field

[0001] This utility model relates to the field of electric vehicle front wheel mudguard technology, and in particular to a full-coverage front wheel mudguard structure that prevents vibration and resonance. Background Technology

[0002] With economic development and increased environmental awareness, electric vehicles have become an important means of transportation for daily commutes. Many models specifically designed for women have also emerged, with the vast majority featuring fully enclosed front mudguards. However, existing front mudguards, due to their relatively long overall length and the fact that they are only secured to the front fork with three screws, result in a long lever arm. This causes the mudguard to vibrate from side to side during riding, and the mudguard may rub against the fork, producing noise and affecting its durability and overall riding experience.

[0003] Therefore, there is an urgent need for a fully enclosed front wheel fender structure that can effectively reduce impacts and improve the stability of the front wheel fenders, thus preventing vibration and resonance. Utility Model Content

[0004] The purpose of this utility model is to provide a full-coverage front wheel mudguard structure that prevents vibration and resonance, solving the technical problems of bumping and abnormal noise caused by excessively long lever arms in existing front wheel mudguards. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a full-coverage front wheel mudguard structure for anti-shake and anti-resonance, including a front wheel mudguard and a front fork. The front fork passes through the front wheel mudguard and is fixedly connected to the top of the front wheel mudguard. A sliding component is provided between the lower part of the front wheel mudguard and the side of the front fork, and the front fork slides relative to the front wheel mudguard.

[0007] Preferably, the sliding component includes:

[0008] The two sets of the skateboards are symmetrically and fixedly connected to the bottom inner wall of the front wheel mudguard;

[0009] The slide rails are symmetrically and fixedly connected to both sides of the front fork, and the slide plate is slidably connected to the slide rails along the extension and retraction direction of the front fork.

[0010] The slide plate moves linearly along the slide rail.

[0011] Preferably, the sliding stroke of the skateboard is greater than the extension stroke of the fork.

[0013] A groove, wherein the groove is formed on the slide rail;

[0014] Rollers, a plurality of said rollers are rotatably connected to the side wall of the slide plate and respectively roll in the slide groove.

[0015] Preferred options also include:

[0016] Two sets of rubber blocks are fixedly connected to both ends of the slide groove, and the slide plate is located between the two sets of rubber blocks.

[0017] Preferred options also include:

[0018] The limiting plates are respectively provided at both ends of the sliding plate, and the limiting plates are arranged opposite to the rubber block.

[0019] Preferred options also include:

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] refer to Figure 1-3 A specific embodiment of this utility model provides a full-coverage front wheel mudguard structure for anti-shaking and anti-resonance, including a front wheel mudguard 1 and a front fork 2. The front fork 2 passes through the front wheel mudguard 1 and is fixedly connected to the top of the front wheel mudguard 1 by three bolts (not marked in the figure). A sliding component is provided between the lower part of the front wheel mudguard 1 and the side of the front fork 2, and the front fork 2 slides relative to the front wheel mudguard 1.

[0034] Existing front wheel mudguards, due to their long overall length, are only secured to the front fork with three screws at the top. This results in a long lever arm at the bottom of the mudguard, causing lateral shaking during riding and resulting in noise from impacts with the front fork, affecting the mudguard's durability and riding experience. This application addresses this issue by using a sliding component to allow relative sliding between the front fork 2 and the front wheel mudguard 1, effectively preventing impacts between them and thus avoiding the problems of impacts and noises caused by the excessively long lever arm.

[0035] Further optimizations to the solution include the following sliding components:

[0036] Two sets of skateboards 8 are symmetrically and fixedly connected to the bottom inner wall of the front wheel mudguard 1;

[0037] The slide rails 3 are symmetrically and fixedly connected to both sides of the front fork 2, and the slide plate 8 is slidably connected to the slide rails 3 along the extension and retraction direction of the front fork 2.

[0038] The slide 8 moves in a straight line along the slide rail 3.

[0039] A sliding plate 8 and a sliding rail 3 are installed between the inner sidewall of the front fork 2 and the bottom of the front wheel mudguard 1. Their main function is to ensure that the sliding plate 8 always slides on the sliding rail 3 during the extension and retraction of the front fork 2 and during vehicle bumps. This prevents the extension and retraction of the front fork 2 from being affected, and also prevents the inner sidewall of the bottom of the front wheel mudguard 1 from contacting or bumping against the front fork 2. In other words, the sliding plate 8 and the sliding rail 3 maintain the distance between the front fork 2 and the inner sidewall of the bottom of the front wheel mudguard 1. Overall, this application effectively avoids the problem of bumps and abnormal noises caused by excessive lever arm of the front wheel mudguard by installing the sliding plate 8 and the sliding rail 3, ensuring the integrity and stability of the front wheel mudguard 1, while also achieving the purpose of anti-shaking and anti-vibration.

[0040] Further optimization of the design resulted in the sliding stroke of skateboard 8 being greater than the extension stroke of front fork 2.

[0041] When the sliding stroke of the skateboard 8 is set to 75mm and the extension stroke of the front fork 2 is set to 70mm, the sliding relationship between the skateboard 8 and the slide rail 3 will not affect the extreme compression or extension state of the front fork 2, thus avoiding affecting the state of the front wheel mudguard 1 when the vehicle is in normal operation.

[0042] Further optimizations to the plan include:

[0043] Slide 5, slide 5 is formed on slide rail 3;

[0044] Rollers 10, several rollers 10 are rotatably connected to the side wall of the slide plate 8, and are respectively rolled and engaged in the slide groove 5.

[0045] The roller 10 uses common metal rollers, and the slide rail 3 uses metal slide rail, thus ensuring the durability between the skateboard 8 and the slide rail 3; at the same time, it also prevents the front wheel mudboard 1 from wobbling back and forth (in the forward and backward directions).

[0046] Further optimizations to the plan include:

[0047] Rubber blocks 6, two sets of rubber blocks 6 are fixedly connected to both ends of the slide groove 5, and the slide plate 8 is located between the two sets of rubber blocks 6.

[0048] The rubber block 6 is mainly for the skateboard 8 in the extreme position. On the one hand, it prevents the skateboard 8 from sliding out of the groove 5 in case of an accident. The rubber block 6 acts as a blocking force. On the other hand, it prevents the skateboard 8 from making hard contact with the groove 5. The rubber block 6 plays a certain protective role.

[0049] Further optimizations to the plan include:

[0050] Limiting plates 11 are provided at both ends of the sliding plate 8, and the limiting plates 11 are positioned opposite to the rubber block 6.

[0051] The limiting plate 11 and the slide plate 8 are an integral structure. The two ends of the slide plate 8 are folded to form the limiting plate 11. In an abnormal state, the limiting plate 11 contacts the rubber block 6 and is limited by the rubber block 6.

[0052] Further optimizations to the plan include:

[0053] Groove 7 is formed by an inward recess on the bottom outer wall of the front wheel mudguard 1;

[0054] Fastener 9 passes through the bottom wall of groove 7 and is threadedly connected to slide plate 8.

[0055] After the skateboard 8 is fixedly connected to the front wheel mudguard 1 by the fastener 9, the fastener 9 is hidden in the groove 7, which to some extent prevents the head of the fastener 9 from bumping into surrounding objects.

[0056] Further optimizations to the plan include:

[0057] Cover plate 4 is snapped into groove 7.

[0058] After the cover plate 4 is placed over the groove 7, the head of the fastener 9 is protected inside the groove 7 to prevent it from rusting due to rainwater, and it also has a certain aesthetic effect.

[0059] Further optimizations to the plan include:

[0060] Countersunk bolts (not shown in the figure) are two sets of countersunk bolts that pass through the slide rail 3 and are threadedly connected to the nuts inside the rubber block 6.

[0061] The rubber block 6 has a nut inside, and by setting countersunk bolts, the connection stability between the rubber block 6 and the slide rail 3 can be effectively guaranteed, and the rubber block 6 can be prevented from being knocked off.
