Description

Technical Field

[0001] This utility model relates to motorcycle technology, and more particularly to a rear fender and a motorcycle. Background Technology

[0002] Current ECU mounting structures mostly use stamped iron ECU brackets to directly connect the ECU to the vehicle frame, with the ECU mounted between the frame and body panels. This structure necessitates the removal of numerous body panels during ECU repair and replacement. Furthermore, the ECU brackets required for mounting the ECU need to be separately designed, manufactured, and then connected to the frame via bolts or welding. This not only increases R&D costs and time but also increases material and labor costs. Moreover, the rigid connection between the ECU bracket and the frame is susceptible to mechanical stress, fatigue fracture, loosening of interfaces, and signal interference due to the high-frequency vibrations of the engine during high-speed operation, affecting the lifespan of the bracket, wiring interfaces, and the ECU itself. Utility Model Content

[0003] The purpose of this invention is to provide a rear fender and motorcycle that can solve the various effects that high-frequency vibration of the engine may have on the ECU due to the hard connection between the ECU and the frame. At the same time, it makes the ECU easier to install and remove, and the rear fender has high structural strength and better protection for the ECU.

[0004] This utility model provides a rear mudguard, including a rear mudguard body and a license plate light mounted on the rear mudguard. The rear mudguard is characterized by being made of elastic and tough plastic. A receiving cavity is provided at the rear upper part of the rear mudguard, and a cover plate is provided above the receiving cavity. An ECU is installed inside the receiving cavity, and the cover plate can be quickly installed or removed from the rear mudguard. This structure uses elastic and tough plastic, improving the connection toughness between the rear mudguard and the vehicle frame, reducing vibration transmitted from the frame to the rear mudguard. Since the ECU is mounted on the rear mudguard, vibration to the ECU is reduced. Simultaneously, the quick-installation and removal structure of the receiving cavity cover allows for convenient and simple installation and removal, improving ECU maintenance and installation. This also extends the service life of both the ECU and the rear mudguard.

[0005] Furthermore, expansion heads are provided on both sides of the front end of the cover plate, and cover plate clips I are provided in the middle and center of the front end of the cover plate. A license plate light mounting clip is provided at the rear end of the cover plate. Expansion head slots are provided in the rear mudguard receiving cavity at positions corresponding to the expansion heads on the cover plate, and slots I that mate with the cover plate clips I are provided in the middle of the front end and on both sides of the rear end of the receiving cavity. By using the expansion heads and slot structures in conjunction, the cover plate can be quickly installed and removed, which is convenient and simple. This improves the efficiency of installation, disassembly, and maintenance.

[0006] Furthermore, two screw holes are spaced apart in the middle of the cover plate, and a license plate light mounting clip is provided at the rear. Mounting lugs I are provided on both sides of the license plate light, and a license plate light slot is provided at the rear to mate with the mounting clip. The license plate light is mounted on the cover plate by screws passing through the mounting lugs I and being fastened to the two screw holes, and by the license plate light mounting clip engaging with the slot. The screw hole and lug structure allows for simple, convenient, and quick installation and removal of the license plate light and cover plate, improving installation efficiency and reducing labor time.

[0007] Furthermore, two openings are provided at the bottom of the receiving cavity, through which two clip nuts are respectively installed on the bottom. Mounting lugs II are provided on both sides of the ECU. The ECU is fixedly installed in the receiving cavity by screws passing through the mounting lugs II and engaging with the clip nuts. The ECU can be quickly installed on the rear fender through a simple structure, improving the efficiency of installation and removal.

[0008] Furthermore, the front end of the receiving cavity has a through hole, which accommodates the wiring harness connected to the ECU plug. This facilitates the wiring harness passing through and connecting to the ECU plug.

[0009] Furthermore, the ECU plug is oriented towards the through hole. This structure avoids bending of the wiring harness, allowing for direct mating with the harness and improving wiring harness connection efficiency.

[0010] This utility model also provides a motorcycle equipped with the aforementioned rear fender. The rear fender with this structure can reduce the likelihood of ECU and rear fender malfunctions, and improve its service life.

[0011] The beneficial effects of this utility model are as follows: Due to the good elasticity and toughness of the rear upper mudguard, the ECU is mounted on the rear mudguard. Furthermore, since the rear mudguard is made of plastic with good elasticity and toughness, the connection between it and the frame forms a soft link, which blocks the transmission of most of the high-frequency vibrations generated during vehicle operation and engine movement, reducing the harsh working conditions of the ECU. In addition, it is convenient to disassemble and install the ECU during maintenance, which can extend the service life of the ECU and the rear mudguard. Attached Figure Description
