[0030] It should be noted that:

[0031] 1. Some terms are used in the description and claims. Those skilled in the art should understand that the same component can be referred to by different terms. The description and claims of the present application do not distinguish components by differences in terms, but by differences in function.

[0032] 2. Unless otherwise defined, technical terms or scientific terms used in the present disclosure should be understood by those skilled in the art in the ordinary sense.

[0033] The present application is described in detail below with reference to the accompanying drawings.

[0034] As shown in the accompanying Figure 1 to the accompanying Figure 4 The present embodiment discloses an upper connecting plate for electric tricycle or motorcycle, comprising a main body.

[0035] The main body is provided with a direction column mounting hole, a direction column mounting boss, a handle mounting seat, a limiting hole, and a connecting seat.

[0036] The main body is provided with a smooth upper surface, and the overall shape is similar to a boomerang, that is, the main body is provided with a transverse section and side wings on both sides of the transverse section.

[0037] Because the transverse section of the main body needs to go through planing and milling, drilling, boring, welding and other operation procedures during processing, and because of the objective shape of the main body, it is easy to produce internal stress, therefore, the plane of the transverse section of the main body is slightly higher than the plane of the side wings of the main body, so that the transverse section of the main body has high mechanical strength.

[0038] The direction column mounting hole is arranged on the center line of the main body transverse section and also on the longitudinal center axis of the main body, and is used for connecting the direction column of the motorcycle, i.e. the direction column of the motorcycle passes through the direction column mounting hole.

[0039] The hole diameter of the direction column mounting hole is processed according to the specifications of the adapted vehicle, and the inner hole diameter size of the embodiment is 23.5 mm.

[0040] The direction column mounting boss is arranged at the direction column mounting hole and is arranged concentrically with the direction column mounting hole. The direction column mounting boss is in a cylindrical shape, and the inner diameter size thereof is preferably 26.5 mm, and the outer diameter size thereof is preferably 46.5 mm or 32.0 mm; the distance between the upper plane of the direction column mounting boss and the upper surface of the main body side wing is 5.4 mm or 3.8 mm. The direction column mounting boss can increase the mechanical strength of the direction column mounting hole, and therefore the direction column mounting boss is preferably integrally processed and formed with the main body, and further the outer side of the connection between the direction column mounting boss and the main body transverse section is arranged as a round corner.

[0041] The handle mounting seat is arranged as two, is symmetrically and equally spaced and is vertically arranged on both sides of the direction column mounting hole.

[0042] The handle mounting seat is arranged as two, is symmetrically and equally spaced and is vertically arranged on both sides of the direction column mounting hole.

[0043] In order to obtain a compact space effect, the vertical projection of the axis of the handle mounting slot on the main body plane passes through the center of the circle projected on the main body plane by the direction column mounting hole; that is, the axis of the handle mounting slot and the axis of the direction column mounting hole are perpendicular and intersected on the vertical plane.

[0044] The upper plane of the handle mounting slot is provided with a fixing hole, and the fixing hole is symmetrically arranged on both sides of the handle mounting slot. In use, the cross beam of the handle is clamped in the handle mounting slot, and the clamp member is locked and fastened by the fixing hole. The interval between the fixing holes on the same handle mounting slot in the embodiment is 32.5 mm, and the interval between the fixing holes on the same side of the two handle mounting slots is 80.0 mm.

[0045] The end of the main body side wing is provided with a limiting hole, and the limiting hole is provided with an opening; the outer side surface of the limiting hole is fixedly provided with a connecting seat. In use, the shock absorber or support column of the vehicle passes through the limiting hole, and the connecting seat is locked and fastened by a bolt, the opening is contracted, and then the shock absorber or support column is tightly held or locked.

[0046] The inner hole diameter of the limiting hole is 37.0mm or 43.0mm, and the center distance between the two limiting holes is 198.0mm or 240.0mm.

[0047] The back of the main body is provided with reinforcing ribs, and the reinforcing ribs are provided as a first reinforcing rib, a second reinforcing rib and a third reinforcing rib.

[0048] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
