Description

Stable connection of the middle guard plate structure Technical Field

[0001] This utility model relates to the field of motorcycles, specifically to a stable and connected center guard plate structure. Background Technology

[0002] In the structural design of motorcycles, the center guard plate is an important protective and decorative component. It is located in the middle of the body, behind the front panel, and connected to the left and right windshields on both sides. It fits closely to the core areas such as the motorcycle frame and engine, and plays a role in protecting key internal components and blocking the impact of flying foreign objects during driving. It also has an important impact on the aesthetics and harmony of the overall appearance of the motorcycle.

[0003] A center skid plate typically consists of a center plate and a rear section. In existing center skid plate structures, the center plate and the rear section are often directly butted together. This connection method easily leads to unevenness on the surfaces of the center plate and the rear section, resulting in insufficient surface flatness and affecting the overall appearance and aesthetics of the motorcycle. Furthermore, it's difficult to ensure a tight connection, resulting in larger gaps between the center plate and the rear section. This not only reduces the protective performance of the center plate for internal vehicle components but also causes the center plate to wobble and make abnormal noises during riding, affecting the riding experience. It also reduces the connection stability of the center plate, posing a safety hazard. Summary of the Invention

[0004] The present invention aims to provide a stable connection structure for the middle guard plate, so as to solve the problem of poor connection stability of existing middle guard plate structures.

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

[0006] The stable middle guard plate structure includes a middle guard plate and a rear section of the middle guard plate. The rear section of the middle guard plate is detachably connected to the rear end of the middle guard plate. The front end of the rear section of the middle guard plate has multiple vertically arranged buckles. The rear end of the middle guard plate has an integrally formed connecting plate. The connection between the connecting plate and the middle guard plate has multiple buckle holes that engage with the buckles. The free end of the connecting plate has a fixing hole. The front center of the rear section of the middle guard plate also has a fixing hole. When the middle guard plate and the rear section of the middle guard plate are connected, the fixing holes on the rear section of the middle guard plate and the fixing holes on the connecting plate are aligned vertically.

[0007] Preferably, as an improvement, the buckle includes a buckle plate and a buckle head. The buckle head is integrally formed on the outside of the free end of the buckle plate. A guide slope is provided on the side of the buckle head away from the buckle plate. The top of the buckle head forms a top surface that cooperates with the inner wall of the buckle hole.

[0008] Preferably, as an improvement, a buckle plate reinforcing rib is provided between the back of the buckle plate and the rear section of the middle guard plate.

[0009] Preferably, as an improvement, a support boss is provided in the middle of the connecting plate, and the top of the support boss can be in contact with the bottom surface of the free end of the rear section of the middle guard plate.

[0010] Preferably, as an improvement, a supporting boss is connected to the connecting plate with a supporting boss reinforcing rib.

[0011] Preferably, as an improvement, the connecting plate is provided with side wind deflector connection holes on both sides, and a positioning hole is provided on one side of the side wind deflector connection hole. Multiple side wind deflector hooks for connecting with the side wind deflectors are vertically provided at the bottom of both sides of the middle guard plate.

[0012] Preferably, as an improvement, the side windshield hook is an L-shaped hook.

[0013] Preferably, as an improvement, there is a hook reinforcing rib connecting the back of the side windshield hook to the center guard plate.

[0014] The principles and beneficial effects of this solution are as follows:

[0015] 1. The connecting plate extends below the front end of the rear section of the center guard plate and connects with it, securing it in the buckle holes. This not only increases the connection area between the two but also distributes the stress more evenly, reducing localized stress concentration when facing external impacts. This helps maintain the stability of the entire center guard plate structure under complex road conditions and improves overall stability. Simultaneously, it allows the front end face of the rear section of the center guard plate to press firmly against the connection end face of the connecting plate and the center guard plate, ensuring a tight connection between the two, reducing vertical errors at the connection point, minimizing gaps, and improving connection stability. Furthermore, the connecting plate extending below the rear section of the center guard plate provides support from the bottom, further enhancing the connection stability.

[0016] 2. This snap-fit ​​structure utilizes an integrated design of the snap-fit ​​plate and the snap-fit ​​head, combined with the precise fit of the guide ramp and the abutment surface. During assembly, the guide ramp guides the snap-fit ​​head to slide smoothly into the snap-fit ​​hole, reducing assembly resistance and improving installation efficiency. The abutment surface at the top of the snap-fit ​​head fits tightly against the inner wall of the snap-fit ​​hole, forming a reliable mechanical lock, effectively preventing the middle guard plate and its rear section from loosening under vibration or external force, ensuring connection stability.

[0017] 3. The reinforcing ribs added to the back of the buckle plate, connected to the rear section of the middle guard plate, significantly enhance the structural rigidity of the buckle, effectively distribute the force, and prevent the buckle from breaking or deforming due to frequent insertion and removal or long-term vibration, ensuring a tight fit between the buckle head and the buckle hole.

[0018] 4. The support boss located in the middle of the connecting plate fits snugly against the bottom surface of the free end of the rear section of the center guard plate, forming a bottom support point for the rear section. This effectively disperses the force on the cantilever end of the rear section of the center guard plate, further enhancing the bending resistance and structural stability of the overall center guard plate structure, and further reducing gaps and surface errors at the connection point. Simultaneously, the presence of the support boss optimizes the force transmission path, evenly distributing impact force across the entire frame of the center guard plate, improving the system's rigidity and reliability, extending the service life of the center guard plate, and ensuring the long-term flatness and aesthetics of the motorcycle's appearance.

[0019] 5. The reinforcing ribs added between the support boss and the connecting plate form a triangular stable structure, which significantly enhances the deformation resistance of the support boss, enabling it to withstand greater vertical pressure and lateral impact. This design effectively prevents the support boss from bending or breaking under long-term load or frequent vibration, ensuring that the rear section of the middle guard plate always receives stable and reliable bottom support, and further reducing stress concentration at the connection between the two.

[0020] 6. The side of the center guard plate connects to the side windshield. The side windshield hooks are hooked into the corresponding hook holes on the side windshield. Simultaneously, the side windshield connection holes on the connecting plate align with the corresponding holes on the end of the side windshield. The connection between the center guard plate and the side windshield is achieved by tightening screws in these two holes. The positioning holes are used to engage with protrusions on the side windshield to position the side windshield. Through the triple positioning and connection of the positioning holes, side windshield hooks, and side windshield connection holes, a stable connection between the center guard plate and the side windshield can be achieved. Placing the positioning holes on one side of the side windshield connection holes, compared to other locations, improves the alignment between the side windshield connection holes and the corresponding connection holes on the side windshield, thereby reducing screw connection errors and further enhancing the connection stability.

[0021] 7. The L-shaped side deflector hooks, after being hooked into the corresponding holes on the side deflector, can move and remain firmly in place within the holes, further improving the connection stability between the center guard plate and the side deflector. Reinforcing ribs are added between the back of the side deflector hooks and the center guard plate, constructing a stable triangular support structure that significantly enhances the deformation resistance and load-bearing capacity of the side deflector hooks.

[0029] The following detailed description illustrates the specific implementation method:

[0030] Example

[0031] As shown in Figure 1, the stable connecting middle guard plate structure includes a middle guard plate 1 and a rear section 2. The rear section 2 is detachably connected to the rear end of the middle guard plate 1. Specifically, as shown in Figure 2, four clips 4 are vertically arranged at the front end of the rear section 2. As shown in Figures 4 and 5, a connecting recessed plate 10 is integrally formed at the rear end of the middle guard plate 1. Four clip holes 15 are opened at the connection between the connecting recessed plate 10 and the middle guard plate 1 to engage with the clips 4. Referring to Figure 3, the clip 4 includes a clip plate 5 and a clip head 6. The clip plate 5 is integrally formed at the bottom of the front end of the rear section 2. A clip plate reinforcing rib 9 is connected between the back of the clip plate 5 and the rear section 2. The clip head 6 is integrally formed on the outside of the free end of the clip plate 5. A guide slope 8 is provided on the side of the clip head 6 away from the clip plate 5. The top of the clip head 6 forms a top surface 7 that engages with the inner wall of the clip hole 15.

[0032] The connecting plate 10 has a fixing hole 3 at its free end, and the middle of the front end of the rear section 2 of the middle guard plate also has a fixing hole 3. When the middle guard plate 1 and the rear section 2 of the middle guard plate are connected, the fixing holes 3 on the rear section 2 of the middle guard plate and the fixing holes 3 on the connecting plate 10 are aligned vertically. The connecting plate 10 has an integrally formed support boss 11 in the middle. The top of the support boss 11 can be in contact with the bottom surface of the free end of the rear section 2 of the middle guard plate to support the front end of the rear section 2 of the middle guard plate (the end connected to the middle guard plate 1). The support boss 11 and the connecting plate 10 are connected by a support boss reinforcing rib 12.

[0033] The connecting plate 10 has side deflector connecting holes 13 on both sides, and a positioning hole 14 on one side of the side deflector connecting holes 13. As shown in Figure 6, the bottom of both sides of the middle guard plate 1 has multiple side deflector hooks 16 integrally formed for connecting with the side deflectors. The side deflector hooks 16 are L-shaped hooks, and the back of the side deflector hooks 16 is connected to the middle guard plate 1 by hook reinforcing ribs 17.

[0034] In practical application, this solution can stably connect the side windshields. When connecting the side windshields, hook the L-shaped side windshield hooks 16 on the bottom of both sides of the center guard plate 1 into the corresponding connecting holes on the side windshields. The L-shaped side windshield hooks 16 can move within the holes and be adjusted to the optimal hooking position. At this time, the positioning hole 14 on one side of the side windshield connecting hole 13 cooperates with the protrusion on the side windshield to accurately position the side windshield, ensuring that the height of the side windshield connecting hole 13 and the corresponding hole on the side windshield is aligned, thus improving the connection accuracy. The center guard plate 1 and the side windshields can be stably connected by using screws to pass through the two holes for locking.

[0035] Furthermore, this assembly method ensures strong stability in the connection between the middle guard plate 1 and the rear section 2, with minimal vertical errors and gaps. During connection, the four clips 4 on the rear section 2 are aligned with the four clip holes 15 and inserted. Because the side of the clip head 6 away from the clip plate 5 has a guide slope 8, it guides the clips 4 smoothly into the clip holes 15. Once the clip head 6 is fully inserted into the clip hole 15, the top abutting surface 7 of the clip head 6 fits tightly against the inner wall of the clip hole 15, forming a mechanical lock. After the clips 4 are inserted into the clip holes 15, the fixing holes 3 on the rear section 2 of the middle guard plate align with the fixing holes 3 on the connecting plate 10. By using bolts or other connecting parts to pass through the two fixing holes 3 and tighten them, a stable connection between the middle guard plate 1 and the rear section 2 can be achieved. At this time, the top of the support boss 11 in the middle of the connecting plate 10 is in contact with the bottom surface of the free end of the rear section 2 of the middle guard plate, providing bottom support for the rear section 2 of the middle guard plate. The support boss 11 and the support boss reinforcing rib 12 between the support boss 11 and the connecting plate 10 further enhance the load-bearing capacity and stability of the support boss 11.
