Description

Technical Field

[0001] This invention relates to the field of home and living technology, specifically to a pedal motorcycle with a protective structure. Background Technology

[0002] Motorcycle exhaust pipes are generally made of metal. They are tubular devices that are connected to the exhaust valve of the engine. The main purpose of motorcycle exhaust pipes is to discharge exhaust gases after combustion and to expel the exhaust gases from the engine.

[0003] Currently, motorcycle exhaust pipe protection structures are typically made of aluminum alloy and carbon fiber composite materials. In terms of manufacturing process, advanced molding technology is used to manufacture the motorcycle exhaust pipe protection structure into a thin plate that fits the shape of the exhaust pipe. The exhaust cover protection plate is installed on the vehicle body with screws. In the event of a side fall, the impact force will act on the protection plate and be absorbed by the protection plate, which can protect the exhaust pipe and prevent the exhaust pipe from being directly exposed to the impact force and thus causing damage to the exhaust pipe.

[0004] However, the existing motorcycle exhaust pipe protective structure is relatively thin. When the motorcycle rolls over, the protective cover will undergo plastic deformation due to the impact of external forces, and it will not be able to effectively absorb and disperse the impact force from the outside. The remaining impact force will still act on the exhaust pipe, which will increase the risk of damage to the exhaust pipe, thereby negatively affecting the normal operation and safety of the motorcycle.

[0005] In view of the above, in order to overcome the aforementioned technical problems, this invention has designed a case name and solved the aforementioned technical problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that the existing motorcycle exhaust pipe protective structure is too thin and cannot effectively absorb and disperse the impact force from the outside. When the motorcycle overturns, some of the impact force will still act directly on the exhaust pipe, causing damage to the exhaust pipe.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides an exhaust pipe protection structure, including an engine head, a vehicle body, and a bracket, as well as a heat dissipation component and a protective component. The heat dissipation component is installed on the outside of the exhaust pipe. The heat dissipation component improves heat dissipation by increasing the contact area between the heat dissipation surface and the air through orderly arranged heat dissipation fins on the surface of the heat dissipation column. The heat dissipation fins are fin-shaped and evenly distributed on three sides of the heat dissipation column. The extended fins contact the air and dissipate the heat from the exhaust pipe, thereby increasing the heat dissipation area and improving heat dissipation efficiency. The heat dissipation component reduces noise by changing the direction and speed of gas flow through orderly arranged silencer plates on the inner wall of the silencer column. The silencer plates are arranged in an arc-shaped array on the inner wall of the silencer column. When the exhaust airflow passes through the arc... When the diaphragm is shaped, the speed and pressure of the airflow change, thereby reducing the noise of the exhaust pipe. The protective component is installed on the outer wall of the heat dissipation component. The protective cover in the protective component is arc-shaped, which can disperse and reduce the direct impact force from the outside, and reduce the impact on the exhaust pipe. When the vehicle rolls over, the protective component absorbs and buffers the vibration from the road surface through the elastic deformation of the pressure spring, so that the vehicle's exhaust pipe does not directly contact the ground, thereby better protecting the safety of the exhaust pipe. When the protective component is subjected to external impact, it first pushes the sliding sleeve through the connecting rod to disperse the impact force to the pressure spring, and then pushes the diaphragm in the heat dissipation component through the telescopic rod to disperse the pressure to the buffer spring, thereby avoiding damage to the exhaust port by the impact force.

[0009] Preferably, the protective assembly includes a support base, a support shaft, a sliding sleeve, a pressure spring, a connecting rod, a protective cover, a telescopic rod, and a return spring. The support base is fixedly installed on the outer wall of the heat dissipation assembly. A support shaft for impact resistance is fixedly installed inside the support base. The support shaft effectively distributes the impact force across the entire vehicle frame, reducing the stress on the protective cover and increasing its stability and strength. The sliding sleeve is slidably installed at both ends of the support shaft. One end of the sliding sleeve is connected to a pressure spring for absorbing vibrations and impacts from the road surface when the vehicle rolls over. The pressure spring is designed to bend and return to its original shape. When the protective cover is impacted, the pressure spring is compressed or bent; when the impact force decreases or disappears, the pressure spring returns to its original shape, releasing the absorbed and stored elastic energy, thereby reducing the stress on the protective cover. To mitigate or eliminate the impact of vibrations and shocks on the exhaust pipe, the support shaft has an annular flange in the middle. When the impact force is large, the annular flange limits the sliding sleeve, causing it to lock onto the end face of the annular flange to prevent the protective component from being damaged by a large impact force. One end of the connecting rod is rotatably installed inside the sliding sleeve, and the other end is rotatably installed inside the protective cover that protects the exhaust pipe from damage by external objects and provides heat insulation. Telescopic rods for support and reset are fixedly installed at both ends of the protective cover. When an impact occurs, the protective cover will be subjected to external force and generate impact. The telescopic rod will be compressed, thereby absorbing part of the impact force. When the external force disappears, the telescopic rod will return to its original shape, resetting the protective cover to its original position, thus achieving the stability and reset function of the protective cover. The reset spring is installed on the outside of the telescopic rod.

[0010] Preferably, the sliding sleeve includes a cylindrical base, an arc-shaped boss, and a U-shaped groove. The cylindrical base is slidably mounted on the circumferential surface of the support shaft, the arc-shaped boss is fixedly mounted above the cylindrical base, the U-shaped groove is formed on the side of the arc-shaped boss, the connecting rod is rotatably mounted inside the U-shaped groove, and the sliding sleeve is slidably connected to the circumferential surface of the support shaft. The sliding sleeve uses its own sliding on the support shaft to disperse external impact force to make the protective component more stable. When the motorcycle encounters a bumpy road or overturns, the sliding sleeve will play a buffering role. When an impact force is applied to the protective cover, the sliding sleeve will slide and transfer some of the impact force to other parts, thereby reducing the direct impact of the impact and improving the stability of the protective component.

[0011] Preferably, a cylindrical boss is fixedly installed on the inner wall of the protective cover. A connecting groove is formed on the lower end face of the cylindrical boss. The connecting groove is used to connect the connecting rod and distribute the external force to the pressure spring, which enhances the load-bearing capacity of the protective component. The protective cover is semi-circular. The semi-circular shape allows the protective cover to withstand greater impact force. The semi-circular design can disperse and reduce the direct impact force from the outside, reduce the impact on the exhaust pipe, and reduce air resistance, which helps to improve the aerodynamic performance of the motorcycle. A grid-like reinforcing rib is fixedly installed on the inner wall of the protective cover to improve its impact resistance. The grid-like reinforcing rib can evenly distribute the load and effectively withstand the impact force, thereby increasing the strength and durability of the protective cover.

[0012] Preferably, the support base includes a mounting hole and a cylindrical through hole. The support base has a transverse T-shaped structure inside. The mounting hole is opened transversely at the right end of the support base. The support shaft is fixedly installed inside the mounting hole. The cylindrical through hole is opened longitudinally at the left end of the support base. The telescopic rod is fixedly installed inside the cylindrical through hole. When the impact force is large, the support base uses the support shaft in the mounting hole to distribute the pressure to the pressure spring, while the telescopic rod distributes the pressure to the buffer spring, thereby improving the load-bearing capacity of the protective component.

[0013] Preferably, the heat dissipation assembly includes a cylindrical shell, a heat dissipation column, a muffler column, and end caps. The cylindrical shell is fixedly mounted on a bracket. Inside the cylindrical shell, a heat dissipation column is fixedly installed to improve the heat dissipation effect of the exhaust pipe. The heat dissipation column increases the heat dissipation surface area, allowing the exhaust pipe to better disperse heat and transfer it to the outside air more quickly. This helps to reduce the temperature of the exhaust pipe and improve the overall heat dissipation efficiency of the exhaust pipe. Inside the heat dissipation column, a muffler column is fixedly installed to reduce exhaust pipe noise. The muffler column causes the airflow to bend and reflect inside the muffler column, thereby reducing noise propagation, reducing exhaust airflow noise, and reducing the sound intensity of the engine exhaust. End caps are fixedly installed at both ends of the cylindrical shell. When the protective assembly is subjected to pressure impact, the telescopic rod will push the muffler column to reduce the pressure through the buffer spring, thereby enhancing the protective performance of the protective assembly.

[0014] Preferably, the cylindrical shell has a circumferential array of heat dissipation grooves, which are fin-shaped. A heat dissipation plate is fixedly installed on the outer wall of the heat dissipation column. The heat dissipation plate is fin-shaped, which improves the heat dissipation effect by increasing the heat dissipation surface area and optimizing the heat transfer method. When the heat dissipation column is installed, the heat dissipation plate extends out of the heat dissipation groove and contacts the air, increasing the surface area of ​​the heat dissipation component so that heat can be more easily dissipated into the surrounding air through the heat dissipation plate, thereby improving the heat dissipation efficiency.

[0015] Preferably, a sound-absorbing plate is fixedly installed on the inner wall of the muffler column. The sound-absorbing plate is circular and reduces noise by changing the direction and speed of gas flow. The circular design has two advantages: firstly, the arc-shaped sound-absorbing plate can convert the kinetic energy of the pulsating airflow into sound energy, absorbing and eliminating part of the exhaust noise; secondly, the arc-shaped sound-absorbing plate can change the path and direction of the airflow, reducing the resonance effect of the airflow and effectively reducing the resonance noise in the exhaust system. An annular gap is left between two adjacent sound-absorbing plates, and a buffer spring is connected inside the annular gap. The annular gap uses the buffer spring connected inside it to reduce the external impact force, thereby enabling the protective component to effectively protect the exhaust pipe and enhance the protective performance of the protective component.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The present invention provides a pedal motorcycle with a protective structure, wherein the protective component disperses and reduces the impact force from the outside through a protective cover, and slides on the support rod through a sliding sleeve to compress the pressure spring in the middle, thereby transferring a portion of the impact force to the pressure spring, thereby effectively reducing the vibration and impact on the protective cover, and mitigating or eliminating the impact on the exhaust pipe.

[0018] 2. The pedal motorcycle with a protective structure described in this invention disperses and reduces the impact force from the outside through the protective cover, and absorbs and buffers the vibration from the outside through the elastic deformation of the pressure spring, so that the exhaust pipe of the vehicle does not directly contact the ground, thereby better protecting the exhaust pipe, preventing damage to the exhaust pipe, and protecting the safety of the rider.

[0019] 3. The present invention provides a pedal motorcycle with a protective structure, wherein the heat dissipation component increases the surface area of ​​the heat dissipation component through the heat dissipation column, so that the heat generated by the exhaust pipe can be transferred to the outside air more quickly, thereby helping to reduce the temperature of the exhaust pipe and improve the overall heat dissipation efficiency of the exhaust pipe. The heat dissipation component divides the exhaust airflow into multiple small airflows through the muffler column, so that the airflow bends and reflects inside the muffler column, thereby reducing the propagation of noise.

[0041] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0042] like Figure 1 As shown, the present invention provides a pedal motorcycle with a protective structure, including a head unit 1, a body 2, and a support 3, as well as a heat dissipation assembly 4 and a protective assembly 5. The heat dissipation assembly 4 is installed outside the exhaust pipe. The heat dissipation assembly 4 increases the contact area between the heat dissipation surface and the air by orderly arranged heat dissipation fins on the surface of the heat dissipation column 42, thereby improving the heat dissipation effect. The heat dissipation fins are fin-shaped and evenly distributed on three sides of the heat dissipation column 42. The heat dissipation fins contact the air and dissipate the heat from the exhaust pipe through the extended fins, thereby increasing the heat dissipation area and improving the heat dissipation efficiency. The heat dissipation assembly 4 uses sound-absorbing plates 431 orderly arranged on the inner wall of the sound-absorbing column 43 to control the direction and speed of air flow. The noise is reduced by the changes in the airflow. The muffler 431 is arranged in an arc-shaped array on the inner wall of the muffler column 43. When the exhaust airflow passes through the arc-shaped muffler 431 from the exhaust pipe, the speed and pressure of the airflow will change, thereby reducing the noise of the exhaust pipe. The protective component 5 is installed on the outer wall of the heat dissipation component 4. The protective cover 56 in the protective component 5 is arc-shaped, which can disperse and reduce the direct impact force from the outside, and reduce the impact on the exhaust pipe. When the vehicle rolls over, the protective component 5 absorbs and buffers the vibration from the road surface through the elastic deformation of the pressure spring 54, so that the vehicle's exhaust pipe does not directly contact the ground, thereby better protecting the safety of the exhaust pipe.

[0043] like Figure 2 , Figure 3 and Figure 4As shown, the protective component 5 includes a support base 51, a support shaft 52, a sliding sleeve 53, a pressure spring 54, a connecting rod 55, a protective cover 56, a telescopic rod 57, and a return spring 58. The support base 51 is fixedly installed on the outer wall of the heat dissipation component 4. The support shaft 52 for bearing impact is fixedly installed inside the support base 51. The function of the support shaft 52 is to effectively distribute the impact force to the entire vehicle body 2 frame, reduce the stress on the protective cover, and increase the stability and strength of the protective cover. The sliding sleeve 53 is slidably installed at both ends of the support shaft 52. One end of the sliding sleeve 53 is connected to a pressure spring 54 for absorbing vibration and impact from the road surface when the vehicle rolls over. An annular flange 521 is provided in the middle of the support shaft 52. When the impact force is large, the annular flange 521 is used to limit the sliding sleeve 53, so that the sliding sleeve 53 is stuck on the end face of the annular flange 521 to prevent the protective component 5 from being damaged by large impact force. The design of the pressure spring 54 allows it to bend and... When the protective cover 56 is impacted, the pressure spring 54 is compressed or bent. When the impact force decreases or disappears, the pressure spring 54 returns to its original state, releasing the absorbed and stored elastic energy, thereby reducing the vibration and impact on the protective cover 56 to mitigate or eliminate the impact on the exhaust pipe. One end of the connecting rod 55 is rotatably installed inside the sliding sleeve 53, and the other end of the connecting rod 55 is rotatably installed inside the protective cover 56, which protects the exhaust pipe from damage by external objects and provides heat insulation. Telescopic rods 57 for support and reset are fixedly installed at both ends of the protective cover 56. When an impact occurs, the protective cover 56 is subjected to external force and the telescopic rod 57 is compressed, thereby absorbing part of the impact force. When the external force disappears, the telescopic rod 57 returns to its original state, resetting the protective cover 56 to its original position, thereby achieving the stability and reset function of the protective cover 56. The reset spring 58 is installed outside the telescopic rod 57.

[0044] When the vehicle rolls over and is subjected to an external impact, the protective cover 56 is affected by the impact force, causing the telescopic rod 57 to press down together. During the pressing process, the impact force is transmitted from the protective cover 56 to the connecting rod 55. At this time, the connecting rod 55 will drive the sliding sleeve 53 to slide on the support rod and squeeze the pressure spring 54 in the middle, thereby reducing the vibration and impact on the protective cover 56. When the impact force is eliminated, the telescopic rod 57 will return to its original state under the action of the return spring 58, returning the protective cover 56 to its original position.

[0045] Compared to existing protective structures, which offer some protection to the exhaust pipe when a vehicle rolls over and is subjected to external impact, these structures are relatively thin. During installation, the protective structure is fixed to the surface of the exhaust pipe with nuts, leading to plastic deformation under significant external impacts. This ineffective absorption and dispersion of the impact force increases the risk of damage to the exhaust pipe. This design utilizes a semi-circular protective cover 56 mounted outside the heat dissipation assembly 4. The semi-circular shape allows the cover 56 to withstand greater impact forces. Under significant external impacts, the semi-circular cover 56 disperses and absorbs the impact force, reducing its effect on the exhaust pipe and thus better protecting both the exhaust pipe and the rider.

[0046] like Figure 6 As shown, the sliding sleeve 53 includes a cylindrical base 531, an arc-shaped boss 532, and a U-shaped groove 533. The cylindrical base 531 is slidably mounted on the circumferential surface of the support shaft 52. The arc-shaped boss 532 is fixedly mounted above the cylindrical base 531. The U-shaped groove 533 is formed on the side of the arc-shaped boss 532. The connecting rod 55 is rotatably mounted inside the U-shaped groove 533. The sliding sleeve 53 is slidably connected to the circumferential surface of the support shaft 52. The sliding sleeve 53 uses its own sliding on the support shaft 52 to disperse external impact force to make the protective component 5 more stable. When the motorcycle encounters a bumpy road or overturns, the sliding sleeve 53 will play a buffering role. When an impact force is applied to the protective cover, the sliding sleeve 53 will slide and transfer part of the impact force to other parts, thereby reducing the direct impact of the impact and improving the stability of the protective component 5.

[0047] During operation, the impact force received by the protective component 5 is converted into power, which drives the sliding sleeve 53 to slide on the support rod by the connecting rod 55. During the sliding process of the sliding sleeve 53, the pressure spring 54 in the middle is squeezed to reduce the external impact force.

[0048] Compared to cylindrical sliding sleeves 53, which are more prone to damage during impact and vibration, the sliding sleeve 53 of this design can absorb some of the impact and vibration during operation, reducing the impact on the support shaft 52, thereby reducing the impact force and vibration transmitted by the protective cover 56. Furthermore, the cylindrical sliding sleeve 53 can provide good guidance on the support shaft 52, ensuring the accuracy and stability of the protective component 5.

[0049] like Figure 7 , Figure 8 and Figure 9As shown, a cylindrical boss 561 is fixedly installed on the inner wall of the protective cover 56. A connecting groove 562 is provided on the lower end face of the cylindrical boss 561. The connecting groove 562 is used to connect the connecting rod 55 and distribute the external force to the pressure spring 54, thereby enhancing the load-bearing capacity of the protective component 5. The protective cover 56 is semi-circular. The semi-circular shape allows the protective cover 56 to withstand greater impact force. The semi-circular design can disperse and reduce the direct impact force from the outside, reduce the impact on the exhaust pipe, and reduce air resistance, which helps to improve the aerodynamic performance of the motorcycle. A grid-like reinforcing rib 563 is fixedly installed on the inner wall of the protective cover 56 to improve the impact resistance of the protective cover 56. The grid-like reinforcing rib 563 can evenly distribute the load and effectively withstand the impact force, thereby increasing the strength and durability of the protective cover.

[0050] When the protective cover 56 is subjected to external impact during operation, the impact force will be absorbed and dispersed by the protective cover 56. Part of the impact force will be directly dispersed and reduced by the arc surface design, part of the impact force will be transmitted to the protective component 5 and absorbed, and the other part of the impact force will be transmitted to the reinforcing rib 563.

[0051] Compared to existing thin-walled protective plates, the semi-circular protective cover 56 of this invention disperses and reduces the direct impact force from the outside through its own structure, and is also provided with a grid-like reinforcing rib 563. The grid-like reinforcing rib 563 can provide support, reduce the risk of deformation and breakage of the protective cover, and remain stable when subjected to impact, thereby increasing the strength and durability of the protective cover.

[0052] like Figure 10 , Figure 11 and Figure 12 As shown, the support base 51 includes a mounting hole 511 and a cylindrical through hole 512. The support base 51 has a transverse T-shaped structure inside. The mounting hole 511 is opened transversely at the right end of the support base 51. The support shaft 52 is fixedly installed inside the mounting hole 511. The cylindrical through hole 512 is opened longitudinally at the left end of the support base 51. The telescopic rod 57 is fixedly installed inside the cylindrical through hole 512. When the impact force is large, the support base 51 uses the support shaft 52 in the mounting hole 511 to distribute the pressure to the pressure spring 54, while the telescopic rod 57 distributes the pressure to the buffer spring 433, thereby improving the load-bearing capacity of the protective component 5.

[0053] like Figure 5As shown, the heat dissipation assembly 4 includes a cylindrical shell 41, a heat dissipation column 42, a muffler column 43, and end caps 44. The cylindrical shell 41 is fixedly mounted on the bracket 3. The heat dissipation column 42, which is used to improve the heat dissipation effect of the exhaust pipe, is fixedly installed inside the cylindrical shell 41. The heat dissipation column 42 increases the heat dissipation surface area, allowing the exhaust pipe to better disperse heat and transfer heat to the outside air more quickly. This helps to reduce the temperature of the exhaust pipe and improve the overall heat dissipation efficiency of the exhaust pipe. The muffler column 43, which is used to reduce exhaust pipe noise, is fixedly installed inside the heat dissipation column 42. The muffler column 43 causes the airflow to bend and reflect inside the muffler column 43, thereby reducing the propagation of noise, reducing exhaust airflow noise, and reducing the sound intensity of the engine exhaust. End caps 44 are fixedly mounted at both ends of the cylindrical shell 41.

[0054] During operation, when the protective component 5 is subjected to pressure impact, the telescopic rod 57 will push the muffler column 43. After being compressed, the muffler column 43 will trigger the buffer spring 433. When the exhaust gas enters the exhaust pipe from the engine, it carries high speed and high temperature. The muffler column 43 disperses and guides the airflow by passing the airflow through the arc-shaped channel on its surface, converting kinetic energy into sound energy. In this way, when the exhaust gas passes through the arc-shaped muffler plate 431, it will produce a noise reduction effect. The heat dissipation column 42 increases the surface area of ​​the heat dissipation component 4 and uses the heat dissipation plate to transfer the high temperature heat to the air to disperse the heat, thereby achieving the effect of reducing the temperature of the exhaust pipe.

[0055] Compared to existing motorcycle protective structures, which are mostly thin-walled plates, prolonged contact with the exhaust pipe can cause the surface temperature to rise, potentially resulting in burns to the rider. The heat dissipation component 4 in this design increases the surface area of ​​the heat dissipation component 4 by using the finned heat dissipation plate 421 in the heat dissipation column 42, thereby improving the heat dissipation efficiency. On the other hand, the arc-shaped muffler 431 in the muffler column 43 causes the exhaust airflow to change in speed and pressure as it passes through the arc-shaped muffler 431, thereby reducing the propagation of noise.

[0056] like Figure 12 , Figure 13 , Figure 14 and Figure 15As shown, the cylindrical outer shell 41 has a circumferential array of heat dissipation grooves 411, which are fin-shaped. A heat dissipation plate 421 is fixedly installed on the outer wall of the heat dissipation column 42. The heat dissipation plate 421 is fin-shaped, which improves the heat dissipation effect by increasing the heat dissipation surface area and optimizing the heat transfer method. When the heat dissipation column 42 is installed, the heat dissipation plate 421 extends out of the heat dissipation groove 411 and contacts the air, increasing the surface area of ​​the heat dissipation component 4 and enabling the protective component 5 to dissipate heat quickly, thereby improving the heat dissipation effect of the protective component 5. The heat dissipation plate 421 increases the surface area of ​​the heat dissipation component 4, making it easier for heat to be dissipated into the surrounding air through the heat dissipation plate 421, thus improving the heat dissipation efficiency of the protective component 5.

[0057] Compared to the traditional heat sink 421, the heat sink column 42 in this design is equipped with a finned heat sink 421. The finned heat sink 421 gives the heat dissipation component 4 a larger surface area and can provide higher heat dissipation efficiency. This is because multiple sets of heat sinks 421 are arrayed on the surface of the heat sink column 42, which increases the heat dissipation surface area and allows heat to be transferred to the surrounding air more quickly, thereby improving heat dissipation efficiency.

[0058] like Figure 16 , Figure 17 and Figure 18 As shown, a sound-absorbing plate 431 is fixedly installed on the inner wall of the sound-absorbing column 43. The sound-absorbing plate 431 is annular and reduces noise by changing the direction and speed of gas flow. The annular design has two advantages: firstly, the arc-shaped sound-absorbing plate 431 can convert the kinetic energy of the pulsating airflow into sound energy, absorbing and eliminating part of the exhaust noise; secondly, the arc-shaped sound-absorbing plate 431 can change the path and direction of the airflow, reducing the resonance effect of the airflow and effectively reducing the resonance noise in the exhaust system. An annular gap 432 is left between two adjacent sound-absorbing plates 431. A buffer spring 433 is connected inside the annular gap 432. The annular gap 432 uses the buffer spring 433 connected inside it to reduce the external impact force, thereby enabling the protective component 5 to effectively protect the exhaust pipe and enhance the safety of the protective component 5.

[0059] Compared to the traditionally used silencer 431, the silencer column 43 of this design is equipped with an annular silencer 431. The annular silencer 431 can generate strong rotation and turbulence in the exhaust airflow by passing it through an annular path, thereby converting kinetic energy into sound energy and changing the airflow path to further reduce noise propagation. Furthermore, an annular gap 432 is left between two adjacent silencers 431, and the buffer spring 433 connected inside the annular gap 432 reduces the external impact force.

[0060] During operation, when the vehicle is in motion, exhaust gas enters the exhaust pipe from the engine. The muffler column 43 disperses and guides the airflow through the arc-shaped channel on the inner surface of the muffler plate 431. The heat dissipation column 42 transfers the high temperature generated by the exhaust pipe to the air for heat dissipation through the fin-shaped heat dissipation plate 421. When the vehicle rolls over and is impacted by an external force, the protective cover 56 is affected by the impact force and drives the telescopic rod 57 to press down together. During the pressing process, the impact force is transmitted from the protective cover 56 to the connecting rod 55. At this time, the connecting rod 55 drives the sliding sleeve 53 to slide on the support rod and squeeze the pressure spring 54 in the middle. At the same time, the telescopic rod 57 pushes the muffler plate 431 in the heat dissipation assembly 4 to disperse the pressure onto the buffer spring 433. When the impact force is eliminated, the telescopic rod 57 will return to its original shape under the action of the return spring 58, returning the protective cover 56 to its original position.

1. A pedal motorcycle with a protective structure, comprising a motor (1), a frame (2), and a support (3), characterized in that, It also includes a heat dissipation component (4) and a protective component (5). The bracket (3) is mounted on the motorcycle, and the heat dissipation component (4) is mounted on the bracket (3). The heat dissipation component (4) increases the contact area between the heat dissipation surface and the air through the heat dissipation plate (421) to improve the heat dissipation effect. At the same time, it changes the direction and speed of the gas flow through the sound-absorbing plate (431) to reduce noise. The protective component (5) is mounted on the outer wall of the heat dissipation component (4). When the vehicle rolls over, the protective component (5) absorbs and buffers the vibration from the road surface through the elastic deformation of the pressure spring (54) so ​​that the vehicle's exhaust pipe does not directly contact the ground, thereby avoiding damage to the exhaust port caused by the impact force. The protective assembly (5) includes a support base (51), a support shaft (52), a sliding sleeve (53), a pressure spring (54), a connecting rod (55), a protective cover (56), a telescopic rod (57), and a return spring (58).

The middle part of the support shaft (52) An annular flange (521) is provided. When the impact force is large, the annular flange (521) is used to limit the sliding sleeve (53) so that the sliding sleeve (53) is stuck on the end face of the annular flange (521) to prevent the protective component (5) from being damaged by the large impact force. One end of the connecting rod (55) is rotatably installed inside the sliding sleeve (53), and the protective cover (56) is rotatably installed on the other end of the connecting rod (55). Both ends of the protective cover (56) are fixedly installed with telescopic rods (57), and the return spring (58) is installed on the outside of the telescopic rod (57).

The cylindrical shell (41) is fixedly installed on the bracket (3). The heat dissipation column (42) is fixedly installed inside the cylindrical shell (41). The sound-absorbing column (43) is fixedly installed inside the heat dissipation column (42). The end caps (44) are fixedly installed at both ends of the cylindrical shell (41). When the protective assembly (5) is subjected to pressure impact, the telescopic rod (57) will push the sound-absorbing column (43) to reduce the pressure through the buffer spring (433), thereby enhancing the protective performance of the protective assembly (5). The inner wall of the silencing column (43) is fixedly equipped with a silencing plate (431). The silencing plate (431) is circular. The circular shape is used to change the direction and speed of gas flow to reduce the noise of the protective component (5). There is an annular gap (432) between two adjacent silencing plates (431). A buffer spring (433) is connected inside the annular gap (432). The annular gap (432) uses the buffer spring (433) connected inside it to reduce the external impact force, thereby enabling the protective component (5) to effectively protect the exhaust pipe.

The U-shaped groove (533) is opened on the side of the arc-shaped boss (532). The connecting rod (55) is rotatably mounted inside the U-shaped groove (533). The sliding sleeve (53) is slidably connected to the circumferential surface of the support shaft (52). The sliding sleeve (53) uses its own sliding on the support shaft (52) to disperse external impact force and make the protective component (5) more stable.

3. A pedal motorcycle with a protective structure according to claim 1, characterized in that: A cylindrical boss (561) is fixedly installed on the inner wall of the protective cover (56). A "U"-shaped connecting groove (562) is opened on the lower end face of the cylindrical boss (561). The "U"-shaped connecting groove (562) is used to connect the connecting rod (55) and disperse the external force to the pressure spring (54), thereby enhancing the load-bearing capacity of the protective component (5). The protective cover (56) is semi-circular. The semi-circular protective cover (56) is used to disperse the external force to the circumferential surface, thereby improving the protective performance of the protective component (5). A reinforcing rib (563) is fixedly installed on the inner wall of the protective cover (56).

4. A pedal motorcycle with a protective structure according to claim 1, characterized in that: The support base (51) has a transverse "T" shaped structure inside. The right end of the support base (51) is provided with a mounting hole (511), and the cylindrical through hole (512) is longitudinally opened at the left end of the support base (51). The telescopic rod (57) is fixedly installed inside the cylindrical through hole (512). The support base (51) uses the support shaft (52) in the mounting hole (511) to distribute the pressure to the pressure spring (54), while the telescopic rod (57) distributes the pressure to the buffer spring (433), thereby improving the load-bearing capacity of the protective component (5).

5.
