Description

Technical Field

[0001] This utility model relates to the field of installation technology, and in particular to a motorcycle tail box fixing structure. Background Technology

[0002] With the rapid development of the motorcycle industry, motorcycles have gradually transformed from simple means of transportation into multifunctional and personalized options. As an important storage accessory for motorcycles, the demand for tail boxes is increasing daily. Tail boxes not only provide users with convenient storage space for items such as helmets, clothing, and tools, but also enhance the practicality and aesthetics of the motorcycle to a certain extent. However, the realization of the tail box's function highly depends on a stable and reliable fixing structure. The performance of the fixing structure directly affects the tail box's safety, convenience, and compatibility. Therefore, the design and optimization of the motorcycle tail box fixing structure has always been a key focus within the industry.

[0003] In the current market, traditional motorcycle tail box fixing structures suffer from the following main problems, making it difficult to meet users' demands for high-quality, highly practical motorcycle accessories:

[0004] First, poor adaptability is one of the main drawbacks of traditional mounting structures. Traditional mounting structures typically employ an integrated design, with relatively fixed dimensions and installation methods, only compatible with specific models and sizes of tail boxes. As user needs for tail boxes diversify, different scenarios may require different capacities and styles of tail boxes; for example, a small tail box may be needed for daily commutes, while a large-capacity tail box is required for long-distance travel. However, traditional mounting structures cannot be flexibly adjusted, and replacing the tail box often requires replacing the entire mounting structure, increasing user costs and significantly limiting the range of tail box options, failing to meet diverse user needs. Therefore, this application provides a motorcycle tail box mounting structure to meet these needs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a motorcycle tail box fixing structure to solve the problem that traditional motorcycle tail box fixing structures usually adopt an integrated design, and their size and installation method are relatively fixed, which can only be adapted to tail boxes of specific models and sizes.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A motorcycle tail box fixing structure includes a fixing plate, on which a fixing structure is mounted for fixing the tail box.

[0008] The fixing structure includes a first sliding groove, which is formed on the inner wall of the fixing plate. A sliding support plate is slidably arranged on the inner wall of the first sliding groove. Several eccentric cam clamping rods are installed on the sliding support plate. A second sliding groove is formed on one side of the fixing plate. Several eccentric cam clamping rods slide against the inner wall of the second sliding groove. Several first fixing bolts are fixedly arranged on the side of the fixing plate away from the second sliding groove.

[0009] Preferably, a fixed support plate is placed on the sliding support plate, and the fixed support plate is fixed to the sliding support plate by a second fixing bolt. The fixed support plate has a plurality of third sliding grooves, and a sliding rod is slidably arranged on the inner wall of the third sliding groove. A fixing block is sleeved on the top of the sliding rod, and a threaded groove is opened on the outer wall of the end of the sliding rod away from the fixing block. A nut is rotatably arranged on the threaded groove, and the sliding rod is tightened and limited by the cooperation between the threaded groove and the nut.

[0010] Preferably, an anti-slip rubber pad is fixedly attached to the inner wall of the fixing block, and the surface of the anti-slip rubber pad has several evenly distributed anti-slip patterns.

[0011] Preferably, wear-resistant lining strips are fixedly provided on both sides of the inner wall of the second sliding groove. The wear-resistant lining strips are made of polytetrafluoroethylene, and the width of the wear-resistant lining strips is adapted to the groove width of the second sliding groove, and the length of the wear-resistant lining strips is consistent with the length of the second sliding groove.

[0012] Preferably, the sliding support plate has a plurality of weight-reducing holes, and the weight-reducing holes are arranged in a parallelogram shape.

[0013] Preferably, the number of the first fixing bolts is 3-6, and the first fixing bolts are evenly distributed along the length of the fixing plate. The end of the first fixing bolt is fitted with an elastic washer, which is made of nitrile rubber.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above solution, by setting up a fixed structure, and by sliding the sliding support plate along the first sliding groove, fine-tuning the fixed support plate, and sliding the slide rod along the third sliding groove, it is possible to fix tail boxes of different sizes and shapes, with a wide range of adaptability, to meet the installation needs of various motorcycle tail boxes.

[0016] The coordinated action of multiple sets of eccentric cam clamping rods with the first and second fixing bolts ensures a firm connection between the fixed structure and the vehicle body, and between the tail box and the fixed structure. The anti-slip rubber pads further increase the friction between the tail box and the fixing block, effectively preventing the tail box from sliding during driving and ensuring driving safety.

Detailed Implementation

[0025] The following is a detailed description of a motorcycle tail box fixing structure provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0026] like Figures 1-4 As shown, an embodiment of this utility model provides a motorcycle tail box fixing structure, including a fixing plate 1, on which a fixing structure is installed for fixing the tail box.

[0027] As the basic load-bearing component of the entire fixed structure, the fixing plate 1 plays a core role in connecting the motorcycle body and the tail box. It is made of high-strength alloy steel, which not only ensures sufficient structural strength to bear the weight of the tail box and its contents, but also has good corrosion resistance and can adapt to different outdoor use environments.

[0028] A fixing structure is installed on the fixing plate 1. The fixing structure is used to fix the tail box. The fixing structure is the core part to achieve the fixing of the tail box. It mainly includes the first sliding groove 2, the sliding support plate 3, the eccentric cam clamping rod 4, the second sliding groove 5, and the first fixing bolt 6. All components work together to ensure that the tail box is installed firmly and is easy to adjust.

[0029] The first sliding groove 2 is formed on the inner wall of the fixed plate 1 and is adapted to the shape of the sliding support plate 3, providing a stable sliding track for the sliding support plate 3. The sliding support plate 3 is installed in the first sliding groove 2 and can slide freely along the length of the groove. It is a key component for bearing the weight of the tail box and realizing position adjustment. The sliding support plate 3 is provided with several weight-reducing holes 13 arranged in parallelograms. The design of the weight-reducing holes 13 effectively reduces the weight of the entire fixed structure while ensuring that the structural strength of the support plate is not affected, reducing the extra load on the motorcycle. At the same time, it also enhances the ventilation and heat dissipation performance of the support plate, avoiding the impact of heat accumulation on component performance during long-term use. In addition, the upper surface of the sliding support plate 3 is treated with anti-slip material, which increases the friction between it and the fixed support plate 7 and prevents the fixed support plate 7 from sliding during use.

[0030] Several eccentric cam clamping rods 4 are installed on the sliding support plate 3. The number of these rods can be reasonably set according to the size and weight of the tail box, usually 2-4, to ensure uniform distribution of clamping force. The eccentric cam clamping rods 4 are made of a combination of high-strength engineering plastic and metal mandrel. The plastic part is made of wear-resistant and impact-resistant nylon material, while the metal mandrel is made of high-quality carbon steel and has been quenched to have extremely high strength and toughness. The working principle of the clamping rod is based on the eccentric cam structure. When the clamping rod is rotated, the eccentric cam will exert a squeezing effect on the inner wall of the second sliding groove 5. The eccentricity of the cam converts the rotation into a linear clamping force, thereby firmly fixing the sliding support plate 3 in the required position. This structure is easy to operate. The clamping rod can be manually rotated to achieve quick clamping and loosening without the need for additional tools, which greatly improves the convenience of tail box installation and disassembly and is the best existing technology.

[0031] A second sliding groove 5 is provided on one side of the fixed plate 1. Several eccentric cam clamping rods 4 can slide on the inner wall of the second sliding groove 5. Its function is to provide space for the eccentric cam clamping rods 4 to slide and clamp. Wear-resistant lining strips are fixedly provided on both sides of the inner wall of the second sliding groove 5. The wear-resistant lining strips are made of polytetrafluoroethylene (PTFE). PTFE has excellent wear resistance, corrosion resistance and low coefficient of friction. It can effectively reduce the friction loss between the eccentric cam clamping rods 4 and the inner wall of the sliding groove, and extend the service life of the components. At the same time, the width of the wear-resistant lining strip is adapted to the groove width of the second sliding groove 5, and the length is consistent with the length of the second sliding groove 5. This ensures that the clamping rods can be uniformly supported and protected throughout the entire sliding range, avoiding wear and deformation of the inner wall of the sliding groove due to long-term friction, and ensuring the stability of the clamping force.

[0032] A number of first fixing bolts 6 are fixedly installed on the side of the fixing plate 1 away from the second sliding groove 5. These bolts are used to connect and fix the entire fixing structure to the motorcycle body. There are 3-6 first fixing bolts 6, which are evenly distributed along the length of the fixing plate 1. The evenly distributed design can make the connection force between the fixing plate 1 and the motorcycle body evenly distributed, avoiding deformation of the fixing plate 1 or damage to the connection parts of the motorcycle body due to excessive local stress. In addition, the end of the first fixing bolt 6 is fitted with an elastic washer. The elastic washer is made of nitrile rubber. Nitrile rubber has good elasticity, oil resistance and aging resistance. During the bolt tightening process, the elastic washer will undergo a certain compression deformation, thereby filling the gap between the bolt and the fixing plate 1, playing the role of anti-loosening, sealing and buffering. This effectively prevents the bolt from loosening due to vibration during motorcycle operation, and further improves the connection stability of the structure.

[0033] The fixed support plate 7 is placed on the sliding support plate 3 and is fixedly connected to the sliding support plate 3 by the second fixing bolt 8. It is the component that directly supports the tail box. The size of the fixed support plate 7 can be customized according to the bottom size of the tail box. Its material is the same as that of the sliding support plate 3, which is high-strength alloy steel, ensuring sufficient load-bearing capacity. The fixed support plate 7 and the sliding support plate 3 are connected by the second fixing bolt 8. The number of bolts is usually 4, which are set at the four corners of the support plate to ensure a firm connection. At the same time, the fixed support plate 7 is provided with waist-shaped holes that are compatible with the second fixing bolt 8, which can adjust the position of the fixed support plate 7 within a certain range, further improving the adaptability of the structure.

[0034] The third sliding groove 9 is formed on the fixed support plate 7 and is evenly distributed along the length or width of the support plate to provide a sliding track for the slide bar 10. The design of the third sliding groove 9 is similar to that of the first sliding groove 2. The length of the groove can be set according to the size of the tail box to meet the fixing requirements of tail boxes of different sizes.

[0035] A sliding rod 10 is slidably mounted on the inner wall of the third sliding groove 9. A fixing block 11 is fitted on the top of the sliding rod 10. The fixing block 11 is used to contact the bottom of the tail box to clamp and position the tail box. The sliding rod 10 is made of high-quality stainless steel, which has good strength and corrosion resistance. Its diameter is adapted to the width of the third sliding groove 9 to ensure that the sliding rod 10 slides smoothly in the groove without shaking. An anti-slip rubber pad is fixedly attached to the inner side wall of the fixing block 11. The anti-slip rubber pad is made of highly elastic natural rubber, which has good anti-slip performance and cushioning performance. Several evenly distributed anti-slip patterns are opened on the surface of the rubber pad. The anti-slip patterns are in a cross grid pattern, which can further increase the friction between the fixing block 11 and the tail box, effectively preventing the tail box from sliding or shifting due to vibration during motorcycle operation. At the same time, the anti-slip rubber pad can also play a cushioning role, reducing the collision impact between the tail box and the fixing block 11 and protecting the surface of the tail box from damage.

[0036] A threaded groove is provided on the outer wall of the end of the slide rod 10 away from the fixing block 11. A nut 12 is rotatably mounted on the threaded groove. The slide rod 10 is tightened and limited by the engagement of the threaded groove and the nut 12. The nut 12 is a high-strength hexagonal nut 12, and its material is matched with that of the slide rod 10. Both are made of stainless steel to avoid electrochemical corrosion due to different materials. When the slide rod 10 is adjusted to the appropriate position, the nut 12 is tightened. The nut 12 will fit tightly against the lower surface of the fixed support plate 7 to generate clamping force, thereby fixing the slide rod 10 in the current position and thus positioning the fixing block 11 to ensure that the tail box is firmly clamped.

[0037] Working principle:

[0038] First, the operator needs to connect the fixing plate 1 to the designated installation position on the motorcycle body using the first fixing bolt 6. During the installation process, it is necessary to ensure that the mounting surface of the fixing plate 1 is in close contact with the mounting surface of the motorcycle body. Then, the first fixing bolt 6 is passed through the bolt holes on the fixing plate 1 and the pre-set mounting holes on the motorcycle body in sequence, and the nut 12 is tightened. At this time, the elastic washer at the end of the first fixing bolt 6 will be compressed, generating an elastic reaction force, which fills the gap between the bolt and the fixing plate 1, effectively preventing the bolt from loosening due to the vibration of the motorcycle. This firmly fixes the fixing plate 1 to the motorcycle body, providing a stable foundation for the subsequent installation of the tail box.

[0039] According to the size of the tail box and installation requirements, the operator can push the sliding support plate 3 to slide along the first sliding groove 2 to adjust the position of the sliding support plate 3 on the fixed plate 1. During the sliding process, the fine grinding treatment of the inner wall of the first sliding groove 2 and the limiting protrusions on both sides ensure that the sliding support plate 3 slides smoothly and does not deviate. When the sliding support plate 3 is adjusted to the appropriate position, the operator rotates the eccentric cam clamping rod 4 on the sliding support plate 3. Due to the structural characteristics of the eccentric cam, the cam will squeeze the wear-resistant lining strip on the inner wall of the second sliding groove 5 during the rotation. As the clamping rod continues to rotate, the squeezing force of the cam on the wear-resistant lining strip gradually increases. When the clamping rod rotates to a specific angle, the squeezing force reaches the maximum value. At this time, the sliding support plate 3 is firmly fixed in the current position and can no longer slide, thus completing the position fixing of the sliding support plate 3.

[0040] Place the fixed support plate 7 on the upper surface of the sliding support plate 3. Adjust the position of the fixed support plate 7 according to the mounting hole position at the bottom of the tail box so that the bolt holes on the fixed support plate 7 are aligned with the corresponding holes on the sliding support plate 3. Then, pass the second fixing bolt 8 through the bolt holes on the fixed support plate 7 and the sliding support plate 3, and tighten the nut 12 to fix the fixed support plate 7 and the sliding support plate 3. If there is a slight deviation in the mounting hole position at the bottom of the tail box, it can be finely adjusted through the waist-shaped hole on the fixed support plate 7 to ensure that the position of the fixed support plate 7 can accurately adapt to the installation requirements of the tail box.

[0041] Place the motorcycle tail box on the fixed support plate 7. Based on the shape and size of the bottom of the tail box, push the slide rod 10 to slide along the third sliding groove 9, so that the fixing block 11 at the top of the slide rod 10 is in close contact with the side wall of the tail box. During the sliding process, the smooth surface of the inner wall of the third sliding groove 9 ensures that the slide rod 10 slides smoothly. When the fixing block 11 is in close contact with the side wall of the tail box, the operator rotates the nut 12 at the bottom of the slide rod 10. Since the nut 12 is engaged with the threaded groove on the slide rod 10, as the nut 12 is tightened, the nut 12 will generate a clamping force with the lower surface of the fixed support plate 7, fixing the slide rod 10 in the current position, thereby making the fixing block 11 firmly clamp the tail box. At this time, the anti-slip rubber pad on the inner side wall of the fixing block 11 is in close contact with the surface of the tail box. The anti-slip texture increases the friction between the two. At the same time, the elastic cushioning effect of the rubber pad can reduce the collision impact between the tail box and the fixing block 11, ensuring that the tail box remains stable during the motorcycle's operation and does not slide or shift.
