It will be appreciated that the stabilizer bar 200 is generally in the form of a "U" shaped cylindrical bar that extends across the front and rear of the vehicle. The middle part of the rod body is hinged with the vehicle body or the vehicle frame by a rubber bushing and is used for assisting the transverse balance and the driving stability of the vehicle body.

Further, the fixing structure 100 further includes a mounting base 13, and the mounting base 13 is connected to the ends of the inner housing 11 and the outer housing 12, so that the inner housing 11, the outer housing 12 and the mounting base 13 enclose each other, thereby forming an arch bridge structure with a hollow-out interior. Specifically, in a cross section orthogonal to the stabilizer bar 200 in the axial direction (i.e., in a front view of the fixing structure 100), the fixing structure 100 is open and the opening direction is oriented toward the stabilizer bar 200.

Further, in the embodiment of the present invention, a plurality of ribs 14 are disposed between the inner case 11 and the outer case 12, i.e., at the hollow portion between the outer case 12 and the inner case 11. The ribs 14 are connected at one end to the inner wall of the inner case 11 and at the other end to the inner wall of the outer case 12, and are arranged radially from the outside to the inside at intervals.

It will be appreciated that the ribs 14 may increase the overall rigidity of the mounting structure 100, allowing it to withstand greater stresses and thus greater stability and reliability.

In the embodiment of the present invention, the reinforcing ribs 14 are in the form of strips or columns;

That is, the reinforcing ribs 14 are provided only on both left and right side surfaces of the fixing structure 100 in the width direction, and the central portion is still a hollow structure. This design is to facilitate the connection member 300 to pass through the fixing structure 100 when the fixing structure 100 is installed, and to further reduce the weight of the fixing structure 100 compared to a solid structure, thereby achieving a light weight design of the vehicle body.

For the fixing structure 100, under a front view angle, the fixing structure 100 is a central axis symmetric figure, wherein the outer shell 12 is a triangle with rounded corners at the intersection points, and one surface of the inner shell 11 departing from the outer shell 12 is U-shaped and opened, so as to be embedded on the stabilizer bar 200. The mounting base 13 is planar so as to be easily mounted on a mounting surface of a vehicle body.

In some embodiments, the shape of the outer shell 12 can be varied, such as rectangular or other convenient shapes, and still fall within the scope of the present invention.

In some embodiments, a plurality of through slots may be designed in the fixing bushing to reduce the weight of the fixing bushing.

Further, it can be seen from the above that the inner housing 11, the outer housing 12 and the mounting base 13 are integrally formed and mutually enclosing housing structures, wherein the thickness of the mounting base 13 is greater than the thickness of the inner housing 11 and/or the outer housing 12, so as to provide the rigidity required when the mounting base is connected with the mounting surface of the vehicle body, and facilitate the machining of the rotary hole. The outer casing 12, the inner casing 11 and the reinforcing ribs 14 are thin-walled structures to further reduce the weight of the fixing structure 100, thereby achieving a light-weight design.

In the course of working, the width that installation base 13 needs can be according to the axial length intercepting of the stabilizer bar 200 of required restraint, and fixed knot structure 100 flexibility ratio under this structure is high, can carry out the adaptability according to different motorcycle types and size and adjust, and the mobility of part is strong.

Referring to fig. 2, 3 and 5, fig. 5 is a transverse cross-sectional view of a fixation structure 100 provided by the present invention; to achieve mounting of the fixing structure 100 on the mounting surface of the vehicle body, the mounting base 13 is a flat surface to be easily brought into contact with the mounting surface on the vehicle body.

The mounting base 13 is provided with a first through hole 15 matched with the connecting piece 300, the outer shell 12 is provided with a second through hole 16 coaxial and communicated with the first through hole 15, and the connecting piece 300 passes through the first through hole 15 through the second through hole 16 and is connected and inserted into a mounting surface of an external object so that the mounting base 13 can be mounted on the external mounting base for fixation.

In the embodiment of the present invention, the area of the outer case 12 corresponding to the second through hole 16 is a plane, so as to facilitate the drilling and the worker to insert the connector 300 through the second through hole 16.

Wherein, the pitch-row between the first through-hole 15 can be adjusted according to specific installation environment, and first through-hole 15 and second through-hole 16 just can accomplish the design through machining, and size accuracy is high, and possesses certain control range, and to different motorcycle types and size, its structural change's adaptability is high equally.

It is understood that the embodiment of the present invention merely illustrates one connection manner in which the connector 300 is installed through the first through hole 15 and the second through hole 16, but the type and specific connection manner of the connector 300 are not limited, and the connector 300 may be a bolt, a long pin, a rivet, a set screw, etc., all of which fall within the mental labor scope of those skilled in the art.
