Description

Technical Field

[0001] The utility model relates to a motorcycle frame, in particular to a motorcycle fender support frame. Background Art

[0002] At present, there are two main structures of motorcycle tail: (1) without rear license plate bracket, such as Figure 1 As shown, the rear end of the rear fender 5 is provided with a taillight and a turn signal light, the rear license plate is hung behind the seat cushion, the fender support frame used includes a welded support tube 3 and a fixing plate 4, and the fender is hung and fixed below the motorcycle fender support frame; (2) as Figure 2 As shown, with a rear license plate bracket, the rear end of the rear fender 5 is connected to the rear license plate bracket 6, and the taillight, turn signal lamp and rear license plate are all arranged on the rear license plate bracket 6. In order to improve the versatility of parts, the fixing plate 4 of the fender support frame in the structure (1) is replaced with a connecting plate 1 and welded to form a new fender support frame, the fender is suspended and fixed under the fender support frame, and the rear license plate bracket 6 is fixedly connected to the support tube 3 through the connecting plate 1, that is, the rear license plate bracket 6 is directly connected to the fender support frame to ensure strength.

[0003] However, welding the fender support frame with the rear license plate bracket 6 needs to be clamped on a new welding tool, which increases the production cost and production process. In the structure with the rear license plate bracket 6, the strength of the connecting plate 1 is increased by using a continuous flange 2 around the side. Figure 2 As shown, in order to ensure that the connecting plate 1 and the rear fender 5 are tightly fitted and prevent interference with the rear fender 5 during connection, the continuous flange 2 can only be folded upward, so that the welding points between the connecting plate 1 and the support tube 3 are both located in the horizontal plane, suitable for bearing horizontal forces, with a single force direction and low connection strength. After adding the rear license plate bracket 6, the connecting plate 1 is subjected to downward tension, and the connection between the connecting plate 1 and the support tube 3 is prone to cracking; because the continuous flange 2 is folded upward, for safety and aesthetics and to avoid interference with other parts above, the height of the continuous flange 2 is not high, resulting in low strength of the connecting plate 1. After installing the rear license plate bracket 6, the connecting plate 1 is prone to deformation. Summary of the invention

[0004] The utility model aims to provide a motorcycle fender support frame, which can meet the processing requirements of two motorcycle tail structures by adopting an existing welding tool, and has high strength, reliable connection and good stability.

[0005] The mudguard support frame in this solution includes two support pipes arranged mirror - image and a fixing plate located between the two support pipes. The fixing plate is fixedly connected to the rear end of the support pipes. It also includes a connecting piece, which includes a frame connecting plate, a bending part, and a bracket connecting plate connected in sequence. The frame connecting plate is located on the fixing plate and is fixedly connected to the fixing plate. Support flanges are provided on both sides of the connecting piece, and the support flanges are in contact with the fixing plate. The bracket connecting plate is fixedly connected to the rear mudguard and the rear license plate bracket.

[0006] The advantages of this utility model are as follows: First, connect the rear mudguard to the support pipe, and then fixedly connect the bracket connecting plate to the rear mudguard and the rear license plate bracket. At this time, the frame connecting plate overlaps on the fixing plate, and then the frame connecting plate can be fixedly connected to the fixing plate by means such as welding or bolt connection. (1) Since only the welding of the fixing plate and the support pipe can use the existing welding tooling, and the installation of the connecting piece does not require positioning tooling fixtures, by installing or not installing the connecting piece, the mudguard support frame of the motorcycle can be adapted to two types of motorcycle tail structures. This simplifies the processing and production steps and reduces the production cost at the same time. (2) Since the frame connecting plate and the fixing plate are surface - connected, the connection strength of the connecting piece is improved, and its connection stability is enhanced. (3) Since the support flanges are in contact with the fixing plate, the support flanges play a supporting role for the bending part, improving the strength of the connecting piece and effectively preventing deformation due to the force of connecting the rear license plate bracket.

[0007] Further, the frame connecting plate is provided with the same fixing holes and through - holes as the fixing plate.

[0008] Furthermore, a limiting flange is provided at the front end of the frame connecting plate. Through the cooperation of the limiting flange and the support flanges, the bracket connecting plate is buckled on the fixing plate. The side of the limiting flange close to the rear mudguard is arc - shaped to adapt to the upward - convex arc surface of the rear mudguard.

[0009] Further, the bracket connecting plate is provided with connecting holes and reinforcing ribs.

[0010] Furthermore, there are four connecting holes and they are distributed in a trapezoidal shape; the reinforcing ribs are in a V - shape. Since the connecting holes are arranged outside the reinforcing ribs, the length of the reinforcing ribs can be extended as much as possible without interfering with the connecting holes.

[0011] Further, a reinforcing protrusion is also provided at the connection part of the bending part and the bracket connecting plate.

[0012] Further, the connecting piece is integrally bent and formed. Description of the Drawings

Specific embodiments

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0021] According to Figures 2 to 6As shown in the figure, the mudguard support frame of a motorcycle includes two support tubes 3 arranged mirror-symmetrically and a fixing plate 4 located between the two support tubes 3. The fixing plate 4 is fixedly connected to the rear ends of the support tubes 3. Specifically, the left and right ends of the fixing plate 4 are lapped on the support tubes 3. The front and rear ends of the fixing plate 4 are provided with flanges 4-1, making the fixing plate 4 in an inverted U shape. In this way, the U-shaped welding line is formed between the fixing plate 4 and the support tubes 3, with multiple force application directions, high connection strength, and good stability. The connecting member 7 includes a frame connecting plate 7-1, a bending portion 7-2, and a bracket connecting plate 7-3 connected in sequence. The frame connecting plate 7-1 is lapped on the fixing plate 4 and fixedly connected to the fixing plate 4. Specifically, the frame connecting plate 7-1 and the fixing plate 4 can be connected by bolts or welded. Support flanges 7-4 are provided on both sides of the connecting member. Specifically, the front edge of the support flange 7-4 abuts against the flange of the fixing plate 4, which is used to increase the strength and stability of the bending portion 7-2 and prevent the bending portion 7-2 from sagging and deforming due to the installation of the rear license plate bracket 6. Since the support flange 7-4 is located on both sides of the bending portion 7-2 and there is a certain distance between the bending portion 7-2 and the rear mudguard 5, the support flange 7-4 can be selected with a relatively high flange height and will not interfere with the mudguard when folded towards the rear mudguard 5. The bracket connecting plate 7-3 can be fixedly connected to the rear mudguard 5 and the rear license plate bracket 6 by bolts. On the basis of the existing mudguard support frame, by adding the connecting member 7, the rear license plate bracket 6 can be added to the tail end of the rear mudguard 5 without using new tooling jigs.

[0022] As a further improvement of the present utility model, the frame connecting plate 7-1 is provided with fixing holes 7-6 and through holes 7-7 identical to those of the fixing plate 4. Bolts pass through the fixing holes 7-6 to directly connect the frame connecting plate 7-1 and the fixing plate 4 without auxiliary tools.

[0023] As a further improvement of the present utility model, the front end of the frame connecting plate 7-1 is provided with a limiting flange 7-5, and the limiting flange 7-5 has the same shape and height as the flange 4-1 on the fixing plate 4. During installation, through the cooperation of the limiting flange 7-5 and the support flange 7-4, the bracket connecting plate 7-3 is buckled on the fixing plate 4 and pre-positioned for the bracket connecting plate 7-3, facilitating the subsequent installation process. To adapt to the upward convex arc surface of the rear mudguard 5, the side of the limiting flange 7-5 close to the rear mudguard 5 is arc-shaped.

[0024] As a further improvement of the present utility model, the bracket connecting plate 7-3 is provided with connecting holes 7-8 and reinforcing ribs 7-9. Specifically, the connecting holes 7-8 are adapted to the connecting holes 7-8 on the rear mudguard 5 and the rear license plate bracket 6, facilitating assembly. The reinforcing ribs 7-9 are used to improve the strength and connection stability of the bracket connecting plate 7-3.

[0025] As a further improvement of the present utility model, there are four connecting holes 7-8 which are trapezoidally distributed, and the reinforcing rib 7-9 is in a V shape. Specifically, the connecting holes 7-8 are arranged on the periphery of the reinforcing rib 7-9. Without interfering with the connecting holes 7-8, the area surrounded by the reinforcing rib 7-9 can be enlarged as much as possible to improve the strength of the bracket connecting plate 7-3.

[0026] As a further improvement of the present utility model, a reinforcing protrusion 7-10 is also provided at the connection between the bending part 7-2 and the bracket connecting plate 7-3. The connecting piece 7 is preferably integrally bent and formed.

[0027] The above are only the embodiments of the present utility model. Common knowledge such as specific structures and characteristics known in the solutions is not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
