Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motorcycle anti-fall guardrails, specifically a motorcycle guardrail structure. Background Technology
[0002] Due to the limitations of its overall structure, the safety of motorcycles cannot be fully guaranteed, and accidents such as falls cannot be avoided when riding a motorcycle.
[0003] When a motorcycle tipes over and collides with the ground, not only will the motorcycle itself be damaged, but the engine will also be impacted, and the rider's legs may be injured, even resulting in injuries such as being squeezed or burned by the engine exhaust pipe. Therefore, guard bars are installed on motorcycles. When the motorcycle tipes over, the guard bar will support the ground, creating a gap between the motorcycle body and the ground, reducing the risk of injury to the rider's legs within the gap. However, existing motorcycle guard bars are of a one-piece structure. When the guard bar deforms or is damaged under stress, the entire guard bar needs to be replaced, resulting in high repair costs.
[0004] Therefore, this utility model provides a motorcycle guard bar structure. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A motorcycle guard bar structure of this utility model includes an upper guard bar; a pair of connecting plates are symmetrically arranged and fixed in the middle of the upper guard bar; a pair of connecting frames are sleeved in the middle of the upper guard bar; the connecting frames and connecting plates are fixed by bolts; a reinforcing rod is bolted between the pair of connecting frames; a lower guard bar is bolted to the side wall of the connecting frame; a load-bearing rod is installed at the end of both the upper and lower guard bars; through the above structure, this guard bar can be disassembled into parts, and damaged parts can be replaced individually in the event of a crash, reducing maintenance costs.
[0007] Preferably, a plug is fixed to the side wall of the force-bearing rod; a groove is formed in the middle of the plug; an inclined sliding groove is formed inside the upper guard bar; a longitudinal sliding groove is formed inside the upper guard bar; the inclined sliding groove and the longitudinal sliding groove are connected; a first slider is slidably connected to the middle of the inclined sliding groove; a second slider is slidably connected to the middle of the longitudinal sliding groove; a connecting rope is fixed between the first slider and the second slider; a spring is installed inside the upper guard bar; a top plate is fixed to the end of the spring facing the plug; with the above structure, when the motorcycle tipes over, the elastic deformation of the spring can absorb part of the kinetic energy, reducing the impact force on the upper guard bar and the connecting frame, thereby reducing damage to the components.
[0008] Preferably, the upper guard bar has an internal thread; the middle of the insert rod is fixed with an external thread; through the above structure, the occurrence of the insert rod being completely ejected from the end of the upper guard bar by the spring can be reduced, so that the insert rod and the spring can cooperate more stably to cushion the motorcycle falling process.
[0009] Preferably, a protective pad is fixed to the inner side wall of the upper guard bar; the protective pad is located at the end of the internal thread near the spring; through the above structure, the occurrence of impact deformation of the external thread can be reduced, thereby reducing the situation where the force-bearing rod is difficult to remove and replace from the end of the upper guard bar after the external thread is deformed.
[0010] Preferably, a shock-resistant rubber sleeve is fixed to the middle of the load-bearing bar; the shock-resistant rubber sleeve is made of polyoxymethylene; through the above structure, the shock resistance of the guard bar can be improved, so that the load-bearing bar can withstand more serious motorcycle tipping accidents before it needs to be replaced.
[0011] Preferably, both the upper and lower guard bars are fixedly connected to a sealing gasket at their ends; the inner diameter of the sealing gasket is smaller than the outer diameter of the upper guard bar; with the above structure, after the load-bearing rod is installed at the end of the upper guard bar, the sealing between the upper guard bar and the load-bearing rod can be improved, reducing the occurrence of external impurities entering the interior of the upper guard bar.
[0012] Preferably, the connecting frame has multiple weight-reduction holes in the middle; the multiple weight-reduction holes are evenly distributed in the middle of the connecting frame; through the above structure, the overall weight of the motorcycle guardrail can be reduced, thereby reducing the overall weight of the motorcycle and improving the overall lightweight effect of the motorcycle.
[0013] Preferably, a bending plate is fixed to the connecting frame; this can effectively increase the overall strength of the guard bar.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The present invention relates to a motorcycle guard bar structure, which connects the upper guard bar, connecting plate, connecting frame, reinforcing rod and lower guard bar in sequence by bolts. This allows for the replacement of damaged components individually after some components are damaged, thereby reducing maintenance costs.
[0016] 2. The present invention relates to a motorcycle guard bar structure, which uses a plug rod to compress a spring when the motorcycle falls, causing the spring to undergo elastic deformation and absorb some of the kinetic energy, thereby reducing the impact force on the upper guard bar and connecting frame, and thus reducing damage to the components.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 2 As shown, a motorcycle guardrail structure according to an embodiment of the present invention includes an upper guardrail 1; a pair of connecting plates 12 are symmetrically arranged and fixedly connected to the middle of the upper guardrail 1; a pair of connecting frames 13 are sleeved on the middle of the upper guardrail 1; the connecting frames 13 and the connecting plates 12 are fixedly connected by bolts; a reinforcing rod 14 is bolted between the pair of connecting frames 13; a lower guardrail 15 is bolted to the side wall of the connecting frame 13; a force-bearing rod 16 is installed at the end of both the upper guardrail 1 and the lower guardrail 15; a bent plate 101 is fixedly connected to the connecting frame 13, and the bent plate 101 is integrally formed with the connecting frame 13; in operation, the pair of connecting frames 13 are first sleeved on the middle of the upper guardrail 1, and then the reinforcing rod 14 is placed between the pair of connecting frames 13 and connected by bolts. First, fix the components, then use bolts to connect a pair of connecting brackets 13 and a pair of connecting plates 12. Then, use bolts to connect and fix a pair of lower guard bars 15 to a pair of connecting brackets 13 respectively. Finally, install multiple force-bearing rods 16 at the ends of the upper guard bar 1 and the lower guard bar 15 respectively, thus assembling a complete motorcycle guard bar. When the motorcycle tilts to one side, the force-bearing rods 16 will hit the ground and be damaged before the motorcycle body. When the impact force is too large, each component may be deformed. At this time, the components can be selectively replaced and repaired according to their damage, while undamaged components can be reused. Through the above structure, this guard bar can be disassembled into parts, and damaged parts can be replaced individually in the event of a crash, reducing maintenance costs.
[0025] like Figures 1 to 4As shown, a rod 2 is fixedly connected to the side wall of the force-bearing rod 16; a groove 21 is provided in the middle of the rod 2; an inclined sliding groove 22 is provided inside the upper guard bar 1; a longitudinal sliding groove 23 is provided inside the upper guard bar 1; the inclined sliding groove 22 and the longitudinal sliding groove 23 are connected; a first slider 24 is slidably connected to the middle of the inclined sliding groove 22; a second slider 25 is slidably connected to the middle of the longitudinal sliding groove 23; a connecting rope 26 is fixedly connected between the first slider 24 and the second slider 25; a spring 27 is installed inside the upper guard bar 1; a top plate 28 is fixedly connected to the end of the spring 27 facing the rod 2; when the tilt of the motorcycle body does not exceed a certain angle, the first slider 24 and the second slider 25 will slide to the lower part of the inclined sliding groove 22 and the longitudinal sliding groove 23 respectively under their own weight. At this time, the rod 2 is inserted, causing the second slider 25 to sink into the groove 21, making it difficult for the rod 2 to be pushed by the spring 27. When the motorcycle tilts, the motorcycle body... After tilting to a certain angle, the highest point of the original inclined slide 22 will become the lowest point. At this time, the first slider 24 will slide under its own weight and pull the second slider 25 through the connecting rope 26, causing the second slider 25 to disengage from the inside of the groove 21. At this time, the insert rod 2 is no longer obstructed, and the force rod 16 will be ejected outward by the spring 27 along with the insert rod 2. After the motorcycle tilts, the force rod 16 contacts the ground and is squeezed into the inside of the upper guard bar 1 by the ground, thereby driving the insert rod 2 to squeeze the spring 27 again. The spring 27 will undergo elastic deformation under force, thereby absorbing the impact force when the upper guard bar 1 hits the ground and buffering the process of the motorcycle falling. Through the above structure, when the motorcycle tilts, the elastic deformation of the spring 27 can absorb part of the kinetic energy, reduce the impact force on the upper guard bar 1 and the connecting frame 13, and thus reduce the damage to the components.
[0026] like Figure 4 As shown, the upper guard bar 1 has an internal thread 3 inside; the middle of the insert rod 2 is fixed with an external thread 31. During operation, when the insert rod 2 is inserted into the end of the upper guard bar 1, the external thread 31 will contact the internal thread 3. By rotating the force rod 16, the external thread 31 passes through the internal thread 3. When the insert rod 2 is ejected outward due to the elastic force of the spring 27, the external thread 31 will be blocked by the internal thread 3, so that the insert rod 2 will not easily detach completely from the inside of the upper guard bar 1. This reduces the occurrence of the situation where the insert rod 2 is completely ejected and cannot properly buffer the motorcycle falling process. Through the above structure, the occurrence of the insert rod 2 being completely ejected from the end of the upper guard bar 1 by the spring 27 can be reduced, so that the insert rod 2 and the spring 27 can cooperate more stably to buffer the motorcycle falling process.
[0027] like Figure 4As shown, a protective pad 4 is fixed to the inner wall of the upper guard bar 1; the protective pad 4 is located at the end of the internal thread 3 near the spring 27; during operation, when the insert rod 2 pops outward with the elastic force of the spring 27, the external thread 31 will hit the side wall of the protective pad 4. Through the elastic deformation of the protective pad 4, the damage to the external thread 31 is reduced. Through the above structure, the occurrence of the external thread 31 being deformed by impact can be reduced, thereby reducing the situation where the force rod 16 is difficult to remove and replace from the end of the upper guard bar 1 after the external thread 31 is deformed.
[0028] like Figure 2 As shown, a shock-absorbing rubber sleeve 5 is fixed to the middle of the force-bearing rod 16; the shock-absorbing rubber sleeve 5 is made of polyoxymethylene; during operation, when the motorcycle falls, the force-bearing rod 16 will come into contact with the ground and generate sliding friction with the ground. By setting the shock-absorbing rubber sleeve 5, the degree of damage to the force-bearing rod 16 can be reduced. Through the above structure, the shock-absorbing ability of the guard bar can be improved, so that the force-bearing rod 16 can withstand more serious motorcycle tipping accidents before it needs to be replaced.
[0029] like Figure 4 As shown, sealing gaskets 6 are fixed to the ends of both the upper guard bar 1 and the lower guard bar 15; the inner diameter of the sealing gasket 6 is smaller than the outer diameter of the upper guard bar 1; with the above structure, after the force-bearing rod 16 is installed at the end of the upper guard bar 1, the sealing between the upper guard bar 1 and the force-bearing rod 16 can be improved, reducing the occurrence of external impurities entering the interior of the upper guard bar 1.
[0030] like Figure 1 As shown, the connecting frame 13 has multiple weight reduction holes 7 in the middle; the multiple weight reduction holes 7 are evenly distributed in the middle of the connecting frame 13; through the above structure, the overall weight of the motorcycle guardrail can be reduced, thereby reducing the overall weight of the motorcycle and improving the overall lightweight effect of the motorcycle.
[0031] like Figure 1 As shown, the ends of the upper guard bar 1 and the lower guard bar 15 are both equipped with load-bearing rods 16; during operation, by setting a bending plate 101 on the connecting frame 13, the guard bar can form a triangular support structure, thereby effectively increasing the overall strength of the guard bar.
[0032] During operation, first, a pair of connecting brackets 13 are fitted onto the middle of the upper guard bar 1. Then, reinforcing rods 14 are placed between the pair of connecting brackets 13 and connected and fixed with bolts. Next, bolts are used to connect the pair of connecting brackets 13 and the pair of connecting plates 12. Then, bolts are used to connect and fix the pair of lower guard bars 15 to the pair of connecting brackets 13 respectively. Finally, multiple load-bearing rods 16 are installed at the ends of the upper guard bar 1 and the lower guard bar 15, thus assembling a complete motorcycle guard bar. When the motorcycle tilts to one side, the load-bearing rods 16 will hit the ground and be damaged before the motorcycle body. When the impact force is too large, all components may be damaged. When the motorcycle is tilted, the first slider 24 and the second slider 25 will slide to the lowest point of the inclined slide groove 22 and the longitudinal slide groove 23 respectively under their own weight. At this time, the insert rod 2 is inserted, so that the second slider 25 sinks into the groove 21, making it difficult for the insert rod 2 to be pushed by the spring 27. When the motorcycle tilts, after the body tilts to a certain angle, the highest point of the inclined slide groove 22 will become the lowest point. At this time, the first slider 24 will slide under its own weight and pull the second slider 25 through the connecting rope 26. 5. The second slider 25 disengages from the groove 21. At this point, the insert rod 2 is no longer obstructed, and the force-bearing rod 16 is ejected outward by the spring 27 along with the insert rod 2. After the motorcycle tilts, the force-bearing rod 16 contacts the ground and is pressed against the inside of the upper guard bar 1 by the ground, thus causing the insert rod 2 to press against the spring 27 again. The spring 27 will undergo elastic deformation under force, thereby absorbing the impact force when the upper guard bar 1 collides with the ground, buffering the motorcycle's fall. When the insert rod 2 is inserted into the end of the upper guard bar 1, the external thread 31 will contact the internal thread 3. By rotating the force-bearing rod 16, the external thread 31 passes through the internal thread 3. When rod 2 is ejected outward due to the elastic force of spring 27, the external thread 31 will be blocked by the internal thread 3, preventing rod 2 from easily detaching completely from the inside of the upper guard bar 1. This reduces the possibility of rod 2 completely ejecting and failing to properly cushion the motorcycle during a fall. When rod 2 is ejected outward due to the elastic force of spring 27, the external thread 31 will impact the side wall of the protective pad 4. The elastic deformation of the protective pad 4 reduces the damage to the external thread 31. When the motorcycle falls, the force-bearing rod 16 will contact the ground and generate sliding friction. The anti-fall rubber sleeve 5 reduces the degree of damage to the force-bearing rod 16.
