TECHNICAL FIELD

[0001] The present application relates to the technical field of motorcycles, in particular to a motorcycle frame vent pipe and a motorcycle frame. BACKGROUND

[0002] The existing motorcycle frame vent pipe has two setting modes, as shown in Figure 4 One is that two end pipes are vertically welded and communicated, and the disadvantage of this mode is that the airflow is not smooth and the venting amount is small; as shown in Figure 5 The other mode is an integrated vent pipe which can only be processed by extrusion forming, and the curvature of the extrusion-formed pipe is too small to easily wrinkle or sag in the extrusion process, and a larger bending radius needs to be set for the pipe to meet the processing requirements, resulting in a larger arrangement space on the motorcycle frame. SUMMARY

[0023] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" used in the present invention to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In the description of the present invention, it should be understood that the terms "connected," "connected," "fixed," etc. used in the present invention should be interpreted broadly. For example, the terms may be fixedly connected, detachably connected, or integrated; may be mechanically connected or welded; may be directly connected or indirectly connected through an intermediate medium; may be internal communication between two elements or an interactive relationship between two elements, unless otherwise clearly defined. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figures 1 to 3 As shown, a frame ventilation pipe of a preferred embodiment of the present invention includes a first semicircular tube 10 and a second semicircular tube 11 that are stamped. The first semicircular tube 10 is provided with a first connecting port 12 extending along the axis, and the second semicircular tube 11 is provided with a second connecting port 13 extending along the axis. The first connecting port 12 and the second connecting port 13 are connected to form a ventilation elbow 14, and a ventilation duct is formed on the inner wall of the ventilation elbow 14.

[0027] The frame ventilation pipe of the present invention has a radial cross-section of the first semicircular tube 10 and the second semicircular tube 11 that is semicircular or semi-elliptical, and the ventilation bend 14 is a split type. The ventilation bend 14 is formed by connecting the first semicircular tube 10 and the second semicircular tube 11. The first semicircular tube 10 and the second semicircular tube 11 are processed by stamping to avoid wrinkling or depression on the surface of the first semicircular tube 10 and the second semicircular tube 11. At the same time, the stamping process has low requirements for the bending radius, so that the setting freedom of the tube diameter and bending radius of the ventilation bend 14 is high, and the miniaturization and lightweight setting of the ventilation bend 14 is realized. The first connecting port 12 and the second connecting port 13 are connected to form the ventilation bend 14, and a ventilation bend pipe 15 is formed inside the ventilation bend 14. The ventilation bend pipe 15 has a smooth transition as a whole and a high degree of airflow smoothness.

[0028] Further, such as Figure 1As shown, the outer walls of the first semicircular tube 10 and the second semicircular tube 11 protrude outward to form a connecting portion 20, which is located at the first connecting port 12 and the second connecting port 13. The first connecting port 12 and the second connecting port 13 are connected by the connecting portion 20 to form an anti-slip portion 21. The first connecting port 12 and the second connecting port 13 are welded and fixed by the connecting portion 20. Since the connecting portion 20 is set on the outer walls of the first semicircular tube 10 and the second semicircular tube 11, a welding position is provided for the first connecting port 12 and the second connecting port 13, reducing the impact of welding on the internal space of the vent elbow 14. At the same time, the convenience of processing and quality inspection is improved. The anti-slip portion 21 is formed by connecting the connecting portion 20, which improves the connection stability of the first semicircular tube 10 and the second semicircular tube 11. The connecting portion 20 can be processed and formed simultaneously when the first semicircular tube 10 and the second semicircular tube 11 are stamped and formed, without additional process costs, and the processing process is simple.

[0029] Further, such as Figures 1 to 3 As shown, the anti-slip portion 21 extends along the outer wall of the ventilation elbow 14 to improve the connection sealing performance between the first semicircular tube 10 and the second semicircular tube 11.

[0030] Further, such as Figure 3 As shown, the radial cross-section of the ventilation elbow 14 is elliptical. Since the first semicircular tube 10 and the second semicircular tube 11 are processed by stamping, the radial cross-section of the ventilation elbow 14 is changed to provide greater setting possibilities.

[0031] Further, such as Figure 3 As shown, the distance between the upper and lower ends of the ventilation elbow 14 is greater than the distance between the left and right ends. While maintaining a certain ventilation volume, the space in the left and right directions of the entire vehicle is further reduced, and the gap between the ventilation elbow and the vehicle body covering is increased.

[0032] A frame, such as Figures 1 to 3 As shown, it includes a vehicle bracket 30 and a vehicle frame vent pipe. One end of the vent elbow 14 is connected to the vehicle bracket 30 , and a gap is formed between the other end of the vent elbow 14 and the vehicle bracket 30 .

[0033] In the vehicle frame of the present invention, one section of the ventilation elbow 14 is connected to the vehicle bracket 30, and there is a gap between the other end of the ventilation elbow 14 and the vehicle bracket 30. The ventilation elbow 14 is a split type, and the ventilation elbow 14 is formed by connecting a first semicircular tube 10 and a second semicircular tube 11. The first semicircular tube 10 and the second semicircular tube 11 are processed by stamping to avoid wrinkling or depression on the surface of the first semicircular tube 10 and the second semicircular tube 11. At the same time, the stamping process has low requirements for the bending radius, so that the setting freedom of the tube diameter and bending radius of the ventilation elbow 14 is high, which helps to reduce the gap distance between the ventilation elbow 14 and the vehicle bracket 30 and reduce the occupied space in the left and right directions of the entire vehicle.

[0034] Further, such as Figure 2 As shown, the gap A is set at 5-50 mm, which reduces the gap distance between the ventilation elbow 14 and the vehicle bracket 30 and reduces the occupied space in the left and right directions of the entire vehicle.

[0035] As one embodiment, the gap A is set at 10-30 mm.

[0036] Further, such as Figure 2 As shown, the outer diameter of the vent elbow 14 is D, the bending radius of the vent elbow 14 is R, and the gap A≤R<1.5D. The gap between the vent elbow 14 and the vehicle bracket 30 is reduced, the space occupied in the left and right directions of the entire vehicle is reduced, and the gap around the vent pipe covering is increased.

[0037] Further, such as Figure 3 As shown, the vehicle support 30 is provided with a vent 31, and the vent elbow 14 is communicated with the vehicle support 30 through the vent 31. The gas in the vehicle support 30 enters the vent elbow 14 through the vent 31 and is discharged.

[0038] In summary, an embodiment of the present invention provides a frame ventilation pipe and its frame, wherein the radial cross-sections of the first semicircular tube 10 and the second semicircular tube 11 are semicircular or semi-elliptical, and the ventilation bend 14 is a split type, and the ventilation bend 14 is formed by connecting the first semicircular tube 10 and the second semicircular tube 11. The first semicircular tube 10 and the second semicircular tube 11 are processed by stamping to avoid wrinkling or depression on the surface of the first semicircular tube 10 and the second semicircular tube 11. At the same time, the stamping process has low requirements for the bending radius, so that the setting freedom of the tube diameter and bending radius of the ventilation bend 14 is high, and the miniaturization and lightweight setting of the ventilation bend 14 is realized. The first connecting port 12 and the second connecting port 13 are connected to form the ventilation bend 14, and a ventilation bend pipe 15 is formed inside the ventilation bend 14. The ventilation bend pipe 15 has a smooth transition as a whole and a high degree of airflow smoothness.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
