Abstract
Description
Technical Field
[0001] This utility model relates to the field of motorcycle mudguard technology, and in particular to a mudguard with adjustable width. Background Technology
[0002] Motorcycle mudguards are plate structures installed behind the outer frame of the wheel. They are usually made of rubber or engineering plastics and are mainly used to protect the motorcycle body and mechanical structure from mud, sand, rainwater, etc.
[0003] Currently, most motorcycle mudguards on the market are one-piece structures with a fixed width that strictly matches tire specifications. When users change to tires of different widths or need to adapt to different motorcycle models, the entire mudguard set must be replaced. This forces manufacturers to develop multiple sets of molds to produce mudguards of different sizes, increasing production costs and inventory pressure, and resulting in resource waste. Furthermore, existing mudguards lack width adjustment functionality, failing to flexibly meet users' personalized modification needs, such as widening tires or changing motorcycle models. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable width mudguard.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An adjustable width mudguard includes a connecting plate, with mudguard side plates inserted into both sides of the connecting plate. Multiple fixing components are evenly arranged and installed at the connection between the mudguard side plates and the connecting plate. The connecting plate includes a replaceable main plate, with side connecting plates symmetrically inserted into both sides of the replaceable main plate. The side of the side connecting plate away from the replaceable main plate is used to connect the mudguard side plates.
[0007] In addition, a preferred structure is that the bottom of the mudguard side plate is connected to a connector, and the mudguard side plate has a connecting plate slot at the side edge for connecting the side connecting plate.
[0008] In addition, a preferred structure is that a plurality of first mounting holes are evenly arranged on the connecting plate slot, and the first mounting holes are used to install and fix the components.
[0009] In addition, a preferred structure is that the replaceable motherboard has symmetrically arranged insert plates on both sides, the insert plates are used to connect to the side connecting plates, and limit protrusions are provided on both the upper and lower surfaces of the insert plates.
[0010] In addition, a preferred structure is that a replaceable motherboard slot is provided on one side of the side connecting plate. The replaceable motherboard slot is used to insert a plug-in board, and limit blocks are provided on the inner walls of both the upper and lower sides of the replaceable motherboard slot. The limit blocks are used to lock the limit protrusions.
[0011] In addition, a preferred structure is that the side plate of the side connecting plate is located on the side away from the replaceable motherboard slot and is used to insert into the connecting plate slot, and a plurality of second mounting holes are evenly arranged on this plate.
[0012] The beneficial effects of this utility model are as follows: By replacing the main plate of different widths, this utility model can match various tire specifications without replacing the entire mudguard, significantly reducing the user's modification cost, flexibly adapting to different tire widths, and manufacturers only need to standardize the production of mudguard side plates, side connecting plates and main plates of various widths, avoiding the development of multiple sets of molds, greatly reducing production costs and storage space, and reducing production and inventory costs.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-7An adjustable width mudguard includes a connecting plate 2, with mudguard side plates 1 inserted into both sides of the connecting plate 2. Multiple fixing components 3 are evenly arranged and installed at the connection between the mudguard side plates 1 and the connecting plate 2. The connecting plate 2 includes a replaceable main plate 21, with side connecting plates 22 symmetrically inserted into both sides of the replaceable main plate 21. The side of the side connecting plate 22 away from the replaceable main plate 21 is used to connect the mudguard side plates 1. The replaceable main plate 21 can be selected with different widths.
[0023] Among them, the bottom of the mudguard side plate 1 is connected to the connector 4, and the mudguard side plate 1 is provided with a connecting plate slot 11 at the side of the connecting plate 22. Multiple first mounting holes 12 are evenly arranged on the connecting plate slot 11. The first mounting holes 12 are used to install the fixing component 3, and the connecting plate slot 11 realizes the assembly.
[0024] Meanwhile, the replaceable motherboard 21 has symmetrically arranged insert plates 211 on both sides. The insert plates 211 are used to connect to the side connecting plate 22. Limiting protrusions 212 are provided on the upper and lower surfaces of the insert plates 211. The limiting protrusions 212 are used to limit the position.
[0025] In addition, a replaceable motherboard slot 222 is provided on one side of the side connecting plate 22. The replaceable motherboard slot 222 is used to insert the expansion board 211. Limiting blocks 223 are provided on the upper and lower inner walls of the replaceable motherboard slot 222. The limiting blocks 223 are used to lock the limiting protrusions 212. The plate body on the other side of the side connecting plate 22 away from the replaceable motherboard slot 222 is used to insert into the connecting board slot 11. A plurality of second mounting holes 221 are evenly arranged on this plate body.
[0026] In this embodiment, when installing mudguards on motorcycles of different models and with different tire widths, different widths of replaceable mainboards 21 are selected. When assembling the mudguard, the insert plate 211 is inserted into the replaceable mainboard slots 222 on both sides, and the limiting protrusion 212 abuts against the limiting block 223 to improve the connection of the insertion. Then, the mudguard side plate 1 is inserted into the side connecting plates 22 on both sides. After aligning the first mounting hole 12 with the second mounting hole 221, the interface is installed with the fixing component 3, and the mudguard assembly is completed. This eliminates the need to produce mudguards of multiple sizes, only different replaceable mainboards 21 need to be produced, reducing processing steps. The width of the mudguard can also be adjusted according to different tire widths by using the replaceable mainboard 21.
[0027] In this utility model, by replacing the replaceable main board 21 with different widths, various tire specifications can be matched without replacing the entire mudguard, which significantly reduces the user's modification cost and flexibly adapts to different tire widths. Manufacturers only need to standardize the production of mudguard side plate 1, side connecting plate 22 and replaceable main board 21 with various widths, avoiding the development of multiple sets of molds, greatly reducing production costs and storage space, and reducing production and inventory costs.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
