Description

Technical Field

[0001] The invention belongs to the technical field of exhaust pipes for motorcycles, and particularly relates to an exhaust pipe and a motorcycle thereof. Background Art

[0002] The motorcycle exhaust pipe is part of the motorcycle exhaust system. The exhaust system is connected to the exhaust port of the engine combustion chamber, through the exhaust manifold, the middle section of the exhaust pipe to the tail end of the exhaust pipe. The function of the exhaust pipe for the vehicle is to discharge the high-temperature exhaust gas after combustion to the rear or side of the vehicle to reduce the impact of the exhaust gas on the driver. Secondly, the internal muffler is used to reduce the noise generated during the high-temperature and high-pressure exhaust gas emission process to an acceptable limit. Existing motorcycle exhaust pipes generally have an anti-scalding structure on the outside of the exhaust pipe to prevent burns caused by touching the exhaust pipe after the motorcycle is parked, and to prevent people in the back seat from touching the high-temperature exhaust pipe. Generally, there is no protection for the exhaust pipe after the motorcycle falls to the ground. For example, application number 2017110422037 discloses a motorcycle exhaust pipe protective cover, including a cover body, which is connected to the exhaust pipe by at least one connecting rod. The cover body has an arc-shaped structure and is located at the end of the exhaust pipe away from the motorcycle. The outer surface of the cover body is provided with a glass fiber layer. Compared with the existing technology, the cover body of the present invention can prevent people from touching the exhaust pipe. The glass fiber layer has an excellent thermal insulation effect and will not be affected by the high-temperature exhaust pipe. People will not get burned after touching the glass fiber layer, thereby eliminating the safety hazards of using motorcycle exhaust pipes.

[0003] The drawback is that existing motorcycles generally have a large curb weight. For example, when the displacement exceeds 500cc, the curb weight of the motorcycle is usually over 200kg. Therefore, the driver can easily reverse when riding slowly or when parking improperly. When the motorcycle reverses, the supporting parts are generally the handlebars, footrests and the tail section of the exhaust pipe that come into contact with the ground. Since the existing exhaust pipe does not have a good protective structure when it leaves the factory, users can only purchase and install anti-collision parts. This can easily cause the exhaust pipe to come into contact with hard ground (asphalt road, gravel) and cause friction damage. Summary of the Invention

[0004] In response to the above-mentioned problems existing in the prior art, the present invention provides an exhaust pipe and a motorcycle thereof, comprising a first connecting pipe, a second connecting pipe, a muffler and a sleeve, wherein the outlet of the first connecting pipe is correspondingly arranged to the inlet of the second connecting pipe, the first connecting pipe and the second connecting pipe are connected through the sleeve, and the outlet of the second connecting pipe is connected to the muffler; the exhaust pipe provided by the present invention is provided with a protective device at the muffler to prevent a motorcycle with a large curb mass from reversing during slow riding or when parked improperly. The protective device of the present invention can directly contact the hard ground, thereby avoiding damage to the exhaust pipe caused by friction caused by contact with the hard ground.

One end of the clamping spring is connected to the spring plate, and the other end of the clamping spring abuts against the inner wall of the clamping portion, so that the driving handle has a tendency to move away from the limit column under the action of the clamping spring.

[0009] Furthermore, the clamping portion as a whole is an "n"-shaped structure.

[0010] Furthermore, the side of the driving handle facing away from the limiting column is covered with a buffer pad, and guide rods are fixed at both ends of the driving handle. The guide rods extend into the guide holes opened on the inner wall of the clamping part, and the opening direction of the guide holes is the same as the moving direction of the driving handle.

[0011] Furthermore, the clamping part is a flexible structure, and a plurality of hinge holes are opened along the length direction of the clamping part. The clamping assembly is installed in a clamping shell, and one end of the clamping part is hinged to one side of the clamping shell.

DETAILED DESCRIPTION

[0018] The present invention will be described in further detail below with reference to the accompanying drawings.

[0019] An exhaust pipe, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a first connecting pipe 1, a second connecting pipe 2, a muffler 3 and a sleeve 4. The outlet of the first connecting pipe 1 is corresponding to the inlet of the second connecting pipe 2. The first connecting pipe 1 and the second connecting pipe 2 are connected through the sleeve 4. The outlet of the second connecting pipe 2 is connected to the muffler 3. Among them, the silencer 3 is provided with a protective device 5, which includes a clamping portion 51 and a clamping assembly installed in an installation cavity 511 opened in the clamping portion 51. The clamping portion 51 is arranged around the outside of the silencer 3, and one end of the clamping assembly extends from the clamping portion 51 and can abut against the outside of the silencer 3.

[0020] According to a specific embodiment provided by the present invention, a first connecting pipe 1 and a second connecting pipe 2 are connected via a sleeve 4. The outlet of the second connecting pipe 2 is connected to the muffler 3. The muffler 3 is provided with a protective device 5. In this embodiment, the protective device 5 can be installed in an appropriate position based on the position where the muffler 3 contacts the ground when the motorcycle is reversed. The clamping portion 51 of the protective device 5 bypasses the muffler 3 and is secured to the outside of the muffler 3 by the clamping assembly. Existing motorcycle exhaust pipes generally have a scalding protection structure installed on the outside of the exhaust pipe, but do not provide protection for the exhaust pipe after the motorcycle falls. The exhaust pipe provided by the present invention is provided with a protective device 5 at the muffler 3 to prevent motorcycles with a large curb mass from reversing during slow riding or when improperly parked. The protective device 5 of the present invention can directly contact hard surfaces (such as asphalt roads or gravel), thereby preventing damage to the exhaust pipe caused by friction between the exhaust pipe and the hard surface.

[0021] Furthermore, the clamping assembly includes a driving handle 52, a transmission component, a clamping component 54 and a limiting rack 31 fixedly installed outside the muffler 3. The transmission component is arranged in the installation cavity 511 opened in the clamping portion 51, and the transmission component is cooperated with the limiting rack 31. The driving handle 52 is located on one side of the transmission component. There are two clamping components 54 and they are arranged on both sides of the driving handle 52. Part of the driving handle 52 extends to the outside of the clamping portion 51, so that under the action of the clamping component 54, the driving handle 52 can act on the transmission component, thereby cooperating with the limiting rack 31.

[0022] According to a specific embodiment provided by the present invention, during installation, attention should also be paid to the installation position of the rotation protection device 5, so that the driving handle 52 faces the outside of the muffler 3. In this way, when the motorcycle exhaust contacts the hard ground, the exhaust pipe can be prevented from being damaged by friction caused by the contact between the exhaust pipe and the hard ground. In order to protect the driving handle 52 and form a buffer, the side of the driving handle 52 facing away from the limiting column 55 is covered with a buffer pad 521. The buffer pad 521 can directly contact the ground. Guide rods 522 are fixed to both ends of the driving handle 52. The guide rods 522 extend into the guide holes opened in the inner wall of the clamping portion 51. The direction of the guide holes is the same as the direction of movement of the driving handle 52. The function of the guide rods 522 is to limit the movement direction of the driving handle 52. The force of the clamping component 54 is transmitted to the limiting column 55 of the transmission component through the driving handle 52. The limiting column 55 abuts against the limiting rack 31 fixedly installed outside the muffler 3 and forms an engagement.

[0023] Furthermore, the transmission component includes a rotating connecting rod 551 and a limiting column 55. The driving handle 52 is a "C"-shaped structure as a whole. Both ends of the driving handle 52 extend into the installation cavity 511. The ends of the driving handle 52 are respectively hinged to the ends of the rotating connecting rod 551. The rotating connecting rod 551 is rotatably installed in the clamping part 51. The end of the rotating connecting rod 551 away from the driving handle 52 is rotatably connected to the limiting column 55. The limiting column 55 is slidably installed in the clamping part 51. The end of the limiting column 55 away from the rotating connecting rod 551 has a limiting tooth. Under the action of the clamping part 54, the limiting tooth can engage with the limiting rack 31.

[0024] According to a specific embodiment provided by the present invention, this embodiment further limits the specific structure of the driving handle 52. The overall "C"-shaped structure can better withstand the impact force from the outside. At the same time, the driving handle 52 is also used by the driver to operate the installation or removal of the protective device 5. The rotating connecting rod 551 can transmit the movement of the driving handle 52 to the limiting column 55. The limiting column 55 is located in the middle of the two rotating connecting rods 551. One end of the limiting column 55 extends out of the hole opened in the clamping part 51 and can slide under the restriction of the hole. The limiting column 55 can move with the movement of the driving handle 52.

[0025] Furthermore, the clamping component 54 includes a clamping spring, and spring plates 541 are fixed to the side surfaces at both ends of the driving handle 52 respectively. One end of the clamping spring is connected to the spring plate 541, and the other end of the clamping spring abuts against the inner wall of the clamping portion 51, so that the driving handle 52 has a tendency to move away from the limiting column 55 under the action of the clamping spring. The length direction of the clamping spring is the same as that of the guide rod 522. The clamping springs are respectively located on the side surfaces at both ends of the driving handle 52. The spring plates 541 are fixed perpendicular to the driving handle 52. The clamping spring is a compression spring. Under the action of the clamping spring, the driving handle 52 is pushed away from the limiting column 55, and the limiting column 55 is driven to press against the limiting rack 31 by rotating the connecting rod 551. At the same time, when the driving handle 52 contacts the hard ground, as shown in FIG. Figure 5 As shown, the driving handle 52 compresses the compression spring to cause deformation, and the compression spring can further buffer, thereby protecting the driving handle 52.

[0026] Furthermore, the clamping portion 51 is an “n”-shaped structure as a whole.

[0027] In order to further securely secure the clamping portion 51 to the muffler 3, a fixing component is fixed to the outside of the muffler 3. The fixing component is arranged on the opposite side of the limiting rack 31. When setting, a suitable installation position of the fixing component can be selected so that the fixing component and the limiting rack 31 are located on the diameter of the muffler 3. The fixing component includes a fixing screw 57 and a connecting plate 56 fixed to the outside of the muffler 3. The connecting plate 56 has an internal thread. The fixing screw 57 passes through the clamping portion 51 and is threadedly connected to the connecting plate 56. A buffer rubber pad is provided on the side of the clamping portion 51 near the connecting plate 56. The buffer rubber pad is in direct contact with the clamping portion 51. The fixing screw 57 extends from the outside into the hole provided in the clamping portion 51 and is threadedly connected to the connecting plate 56. The purpose of this arrangement is that when the motorcycle falls to the ground, the driving handle 52 contacts the hard ground, and the driving handle 52 compresses the compression spring to cause deformation. At this time, the limiting column 55 disengages from the limiting rack 31. Due to the provision of a fixing component, the clamping part 51 is prevented from moving relative to the muffler 3.

[0028] Furthermore, the clamping portion 51 is a flexible structure, such as Figure 6 As shown, the clamping assembly is installed in a clamping shell, one end of the clamping portion 51 is hinged to one side of the clamping shell, the clamping portion 51 can be arranged around the outside of the muffler 3 and the other end can be connected to the other side of the clamping shell.

[0029] According to a specific embodiment provided by the present invention, this embodiment provides a clamping portion 51 with another structure. Unlike the previous embodiment, the clamping portion 51 of this embodiment is a flexible structure, that is, it can adopt a flexible polymer structure with flame retardant properties. In addition, in this embodiment, the clamping assembly is installed in a clamping shell, and the clamping shell has a plate body 512 on one side. One end of the clamping portion 51 is hinged to a hinge rod provided on the plate body 512. The clamping portion 51 has a plurality of hinge holes along the length direction, and the other end of the clamping portion 51 is hinged to a hinge rod provided on the other side of the plate body 512. In this embodiment, the clamping portion 51 can be attached to the outside of the muffler 3, thereby fixing the protective device 5 to the muffler 3.

[0030] Furthermore, if Figure 4 As shown, the clamping portion 51 or the clamping shell is threadedly connected to an anti-theft screw 513, one end of which extends into the mounting cavity 511 and abuts against the end of the guide rod 522. To prevent theft by people with bad intentions, in this embodiment, the clamping portion 51 or the clamping shell is threadedly connected to the anti-theft screw 513. The anti-theft screw 513 is located at one end of the driving handle 52 and extends into the mounting cavity 511 through a screw hole provided in the clamping portion 51 or the clamping shell. The anti-theft screw 513 abuts against the end of the guide rod 522, restricting the driving handle 52 from being struck by the ground, thereby limiting the movement of the driving handle 52 and allowing the clamping portion 51 to be firmly fixed to the muffler 3.

[0031] In addition, the present invention also seeks protection for a motorcycle comprising an engine 6 , a motorcycle body 7 and any one of the exhaust pipes described above, wherein the engine 6 is drivingly connected to the motorcycle body 7 , and the inlet of the first connecting pipe 1 is connected to the engine 6 .
