Description

Technical Field

[0001] The utility model belongs to the technical field of motorcycles and relates to a motorcycle. Background Art

[0002] The motorcycle high-voltage package is an important part of the motorcycle ignition system. It can convert the power supply into high-voltage current, so that the spark plug can generate sparks to ignite the mixed gas in the engine to achieve work. However, when the motorcycle is equipped with a V-cylinder engine, the high-voltage package is difficult to maintain, and it is difficult to avoid the situation where the frame blocks the high-voltage package.

[0003] The patent application publication number CN114483359A discloses a water-cooled engine including a water-cooled cylinder and an ignition device. The water-cooled cylinder includes a cylinder head and a cylinder body, and the cylinder body is connected to the cylinder head. The ignition device includes a spark plug and an ignition coil, and the ignition coil is connected to the spark plug through a connecting wire. The spark plug is installed on the cylinder head, and the ignition coil is installed on the cylinder body, and the ignition coil and the spark plug are located on the same side of the water-cooled cylinder.

[0004] The ignition coil of the above structure protrudes outward, which is not conducive to the arrangement of components and has poor compactness, and the frame easily blocks it, making maintenance inconvenient. Therefore, a person skilled in the art can easily consider changing the direction of the frame beam tube so that the frame beam tube bypasses the location where the high-voltage package is installed, and the protruding high-voltage package is arranged at the same height as the frame beam at that location. Utility Model Content

[0005] The utility model aims at the above-mentioned problems existing in the prior art and provides a motorcycle. The technical problem to be solved by the utility model is: how to improve the compactness of the arrangement of the high-voltage package of the motorcycle while ensuring the convenience of maintenance.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A motorcycle comprises an engine and a frame, wherein the frame comprises a main pipe beam and a secondary pipe beam arranged in sequence along the longitudinal direction, and a columnar ignition high-voltage package is connected to the engine. The motorcycle is characterized in that a top surface of the engine has a recess formed by a downward depression, and an outer end of the ignition high-voltage package is located in the recess, and the main pipe beam and the secondary pipe beam are fixedly connected by a connecting beam, and the connecting beam is opposite to the recess below, and a maintenance opening is provided in the middle of the connecting beam, which passes through from top to bottom and allows the ignition high-voltage package to pass through from bottom to top.

[0008] The engine is the power source of the motorcycle, the frame is the installation frame of the body parts, the main pipe beam can provide an installation limit foundation for parts such as the fuel tank, the auxiliary pipe beam is arranged backward and connected to the main pipe beam, and can participate in the limit fixation of the engine. The ignition high-voltage package is an existing component with a columnar end for extending into the combustion chamber to realize engine ignition. Each pipe beam is a hollow pipe to achieve lightweight effect while ensuring structural strength. By setting a notch on the top surface of the engine, the outer end of the ignition high-voltage package is arranged in the notch, and an independent receiving beam is set to connect the main pipe beam and the auxiliary pipe beam, so that the receiving beam is arranged above the notch and an inspection port is set on the receiving beam. In this way, the ignition high-voltage package fully utilizes the space occupied by the engine, which is conducive to reducing the installation height while realizing installation, thereby enabling the frame to be arranged closer to the engine to improve the compactness of the structure. At the same time, the receiving beam is conducive to providing protection for the high-voltage package in the notch while ensuring the connection strength, and the inspection port on it ensures that the maintenance personnel can conveniently take out the ignition high-voltage package from the inside for replacement and maintenance without having to remove the entire engine, thereby ensuring the convenience of maintenance while improving the compactness of the motorcycle high-voltage package arrangement.

[0009] In the above motorcycle, the notch is open along the longitudinal direction toward the side where the auxiliary pipe beam is located, and the side of the receiving beam facing the engine also has a clearance groove, and the clearance groove is opposite to the lateral opening of the notch. This is conducive to the wiring harness on the ignition high-voltage package to smoothly extend through the lateral opening, so that the ignition high-voltage package works stably, and at the same time, the setting of the clearance groove allows the wiring harness to fully utilize the spatial arrangement of the receiving beam and improve the compactness of the structure.

[0010] In the above-mentioned motorcycle, the receiving beam includes an inspection section and a shielding section connected in sequence, the inspection section is fixedly connected to the main pipe beam, the shielding section is fixedly connected to the auxiliary pipe beam and is bent downward relative to the inspection section, the inspection port is located on the inspection section, the inspection section is opposite to the recess in the up-down direction, the shielding section is opposite to the lateral opening of the recess in the longitudinal direction, and the clearance groove is located on the shielding section. In this way, during the driving of the motorcycle, the air flowing through the longitudinal direction can directly rush into the shielding section and enter the clearance groove to form a wind, and the air flowing out of the turning direction will enter the recess to dissipate heat for the high-voltage ignition package, and then most of the air after absorbing heat can escape upward from the inspection port under the guidance of the inner wall of the recess, thereby improving the heat dissipation effect of the ignition high-voltage package and ensuring the working life.

[0011] In the above motorcycle, the inner wall of the clearance groove has a guide surface inclined from top to bottom toward the side where the notch is located. This is conducive to further guiding the air rushing into the clearance groove along the guide surface through the lateral opening of the notch into the notch, thereby improving the heat dissipation effect of the ignition high-voltage package.

[0012] In the above motorcycle, the auxiliary tube beam is fixedly connected to a top support beam arranged longitudinally away from the main tube beam, and a longitudinally arranged seat tube beam is fixedly connected between the receiving beam and the upper end of the top support beam. The seat tube beam is used to provide support for the riding position of the motorcycle, so that the seat tube beam, the top support beam and the auxiliary tube beam form a triangular support structure, which is conducive to ensuring the overall stability of the frame.

[0013] In the above motorcycle, there are two seat tube beams, one end of each of which is connected to the lateral sides of the receiving beam, and the other ends of each of which is fixedly connected to the top support beam, which is conducive to improving the supporting effect of the riding position and ensuring the supporting stability.

[0014] In the above motorcycle, the two lateral sides of the receiving beam have protruding positioning columns, and the end of the seat tube beam is fixedly sleeved on the periphery of the positioning columns. In this way, the seat tube beam can be rigidly supported by the receiving beam in the vertical direction, which is conducive to further improving the structural stability of the seat tube beam.

[0015] In the above motorcycle, the main pipe beam is a round pipe and the auxiliary pipe beam is a square pipe. The main pipe beam arranged nearly horizontally has a stronger load-bearing capacity, while the auxiliary pipe beam tilted downwards is a square pipe with better load-bearing capacity, and the two realize a natural transition through an independent connecting beam.

[0016] In the above motorcycle, the open edge of the inspection port is processed with rounded corners, which makes it easier for maintenance personnel to replace the ignition high-voltage package and avoids scratches and damage to the ignition high-voltage package.

[0017] In the above motorcycle, the connecting beam is a steel casting, so that the connecting beam can realize a more complex shape design while ensuring the connection strength, thereby ensuring structural stability and convenient maintenance.

[0018] Compared with the prior art, the advantages of the utility model are as follows:

[0019] The ignition high-voltage package in the motorcycle makes full use of the space occupied by the engine to facilitate installation while reducing the installation height, so that the frame can be arranged closer to the engine to improve the compactness of the structure. At the same time, the receiving beam is beneficial to provide protection for the high-voltage package in the recess while ensuring the connection strength, and the inspection port thereon ensures that maintenance personnel can easily take out the ignition high-voltage package from the inside for replacement and maintenance without having to remove the entire engine, thereby ensuring the convenience of maintenance while improving the compactness of the arrangement of the motorcycle high-voltage package.

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figure 1-5As shown, the motorcycle includes an engine 1 and a frame 2, the frame 2 includes a main pipe beam 21 and a secondary pipe beam 22 arranged in sequence along the longitudinal direction, the engine 1 is connected to a columnar ignition high-voltage package 3, the top surface of the engine 1 has a recess 11 formed by a downward depression, the outer end of the ignition high-voltage package 3 is located in the recess 11, the main pipe beam 21 and the secondary pipe beam 22 are welded and fixedly connected by a strip-shaped receiving beam 23, the receiving beam 23 is opposite to the recess 11 below, and the middle part of the receiving beam 23 has an inspection port 231 that runs through from top to bottom and allows the ignition high-voltage package 3 to pass from bottom to top. The engine 1 is the power source of the motorcycle, the frame 2 is the mounting frame of the body parts, the main pipe beam 21 can provide a mounting limit base for parts such as the fuel tank, the auxiliary pipe beam 22 is arranged rearward and connected to the main pipe beam 21, and can participate in the limit fixation of the engine 1, the ignition high-pressure package 3 is an existing component with a columnar end for extending into the combustion chamber to realize the ignition of the engine 1, and each pipe beam is a hollow pipe to achieve a lightweight effect while ensuring structural strength. By setting a notch 11 on the top surface of the engine 1, the outer end of the ignition high-voltage package 3 is arranged in the notch 11, and an independent receiving beam 23 is set to connect the main pipe beam 21 and the auxiliary pipe beam 22, so that the receiving beam 23 is arranged above the notch 11 and an inspection port 231 is set on the receiving beam 23, so that the ignition high-voltage package 3 makes full use of the space occupied by the engine 1, which is conducive to reducing the installation height while achieving installation, so that the frame 2 can be arranged closer to the engine 1 to improve the compactness of the structure, and the receiving beam 23 is conducive to providing protection for the high-voltage package in the notch 11 while ensuring the connection strength, and the inspection port 231 thereon ensures that the maintenance personnel can conveniently take out the ignition high-voltage package 3 from the inside for replacement and maintenance without having to remove the entire engine 1, thereby ensuring the convenience of maintenance while improving the compactness of the motorcycle high-voltage package arrangement. The open edge of the inspection port 231 is processed with a rounded transition. This is conducive to making it more convenient for maintenance personnel to replace the ignition high-voltage package 3, while avoiding scratches and damage to the ignition high-voltage package 3. The notch 11 is open along the longitudinal direction toward the side where the auxiliary pipe beam 22 is located, and the side of the receiving beam 23 facing the engine 1 also has a clearance groove 232, which is opposite to the lateral opening of the notch 11. This is conducive to the wiring harness on the ignition high-voltage package 3 to smoothly extend through the lateral opening, so that the ignition high-voltage package 3 works stably. At the same time, the arrangement of the clearance groove 232 allows the wiring harness to fully utilize the spatial arrangement of the receiving beam 23, thereby improving the compactness of the structure. Furthermore, the receiving beam 23 includes an inspection section 233 and a shielding section 234 which are connected in sequence. The inspection section 233 is fixedly connected to the main beam 21, and the shielding section 234 is fixedly connected to the auxiliary beam 22 and is bent downward relative to the inspection section 233. The inspection opening 231 is located on the inspection section 233, and the inspection section 233 is opposite to the recess 11 in the up and down directions. The shielding section 234 is opposite to the lateral opening of the recess 11 in the longitudinal direction, and the clearance groove 232 is located on the shielding section 234.In this way, during the driving of the motorcycle, the air flowing longitudinally can directly rush into the shielding section 234 and enter the clearance groove 232 to form a wind, and the air flowing out of the turning direction will enter the recess 11 to dissipate heat for the high-voltage ignition package. After that, most of the air after absorbing heat can escape upward from the inspection port 231 under the guidance of the inner wall of the recess 11, thereby improving the heat dissipation effect of the ignition high-voltage package 3 and ensuring the service life. Preferably, the inner wall of the clearance groove 232 has a guide surface 2321 inclined from top to bottom toward the side where the recess 11 is located. This is conducive to further guiding the air rushing into the clearance groove 232 to enter the recess 11 along the guide surface 2321 through the lateral opening of the recess 11, thereby improving the heat dissipation effect of the ignition high-voltage package 3.

A longitudinally arranged seat tube beam 25 is fixedly connected between the receiving beam 23 and the upper end of the top support beam 24. The seat tube beam 25 is used to provide support for the riding position of the motorcycle, so that the seat tube beam 25, the top support beam 24 and the auxiliary tube beam 22 form a triangular support structure, which is conducive to ensuring the overall stability of the frame 2. There are two seat tube beams 25, one end of the two seat tube beams 25 is respectively connected to the lateral sides of the receiving beam 23, and the other ends of the two seat tube beams 25 are respectively fixedly connected to the two branches of the top support beam 24. This is conducive to improving the support effect for the riding position and ensuring the support stability. The lateral sides of the receiving beam 23 are each provided with a lateral protruding positioning column 235, and the end of the seat tube beam 25 is fixedly sleeved on the periphery of the positioning column 235. In this way, the seat tube beam 25 can obtain rigid support from the receiving beam 23 in the vertical direction, which is conducive to further improving the structural stability of the seat tube beam 25. Preferably, the main tube beam 21 is a round tube and the auxiliary tube beam 22 is a square tube. The main tube beam 21 arranged nearly horizontally has a stronger bearing capacity, while the auxiliary tube beam 22 tilted downward as a square tube has a better bearing capacity. The two are naturally transitioned through the independent receiving beam 23. The receiving beam 23 is a cast steel part. In this way, the receiving beam 23 can realize a more complex shape design while ensuring the connection strength, ensuring structural stability and convenient maintenance.
