Description

Technical Field

[0001] This utility model relates to the field of vehicle frame assembly technology, and in particular to a motorcycle frame. Background Technology

[0002] Currently, the rear seat mounting plate on motorcycles is generally suspended above the wheel. This means there's no supporting component connecting the rear seat mounting plate to the rear wheel axle, making it inconvenient to install the license plate. Most motorcycles mount the license plate on the rear mudguard, but the mudguard's purpose is to block mud splashed up during riding, and the mudguard itself is easily contaminated by mud.

[0003] The license plate mounted on the mudguard is also very easy to get dirty. The stains on the license plate may even obscure the information on it. When the vehicle is in motion, the license plate may also be scratched by sand and gravel mixed in with splashed mud, which will damage the license plate. Moreover, when using motorcycles to carry children, children's seats are purchased separately to provide a relatively safe riding environment, especially for small motorcycles, which have separate seat cushions and backrests at the rear. According to the current motorcycle carrying regulations, the utilization rate of the rear seat of small motorcycles is low. Chinese patent discloses a "motorcycle frame" with application number "CN202320375464.5". The device includes a mounting rod, a second pin, a rocker arm, a third pin, a shock absorber, a sliding rod, a sliding frame, and a second spring. A connecting plate is movably mounted on the motorcycle frame body, with fixing bolts fixed to the connecting plate. A connecting mechanism is also mounted on the connecting plate. This device facilitates quick and easy license plate installation, improving work efficiency. It also dampens the license plate frame on the motorcycle frame, preventing the license plate from being shaken off. However, this device lacks an embedded structure to protect the license plate from scratches. Therefore, to further improve the practicality of the device, we provide a motorcycle frame to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a motorcycle frame. The rear surface of the motorcycle frame body is fixed to the license plate by mounting screws in the mounting holes, so that the license plate is embedded in the mounting groove of the license plate fixing bracket. This helps to protect the license plate from damage and also solves the problem that the license plate is easily contaminated due to its low mounting position. The force between the fixing rod and the front surface of the seat, as well as the strong fixation of the guardrail into the fixing groove, provide different levels of safety protection for the child seat, and also eliminate the need to purchase an additional child seat, thus improving the practicality of the device. By rotating the child seat, the seat can be changed from "use state" to "storage state", which not only improves the flexibility of the device, but also saves space, is conducive to daily use, and provides certain support for the rider.

[0005] This utility model also provides a motorcycle frame having the above-mentioned features, comprising: a frame body, a seat fixedly connected to the upper surface of the frame body, a child seat rotatably connected to the surface of the frame body, the child seat comprising a guardrail, a fixing rod, a handrail, reinforcing ribs, and an anti-slip sleeve, the guardrail being rotatably connected to the side of the frame body via an axle, a support frame fixedly connected to the rear surface of the frame body, a license plate fixing frame fixedly connected to the bottom surface of the support frame, an installation groove being provided on the surface of the license plate fixing frame, an installation hole being provided on the surface of the installation groove, and a fixing block being fixedly connected to the upper surface of the license plate fixing frame.

[0006] According to the present invention, a motorcycle frame has a fixing groove on its upper surface, and the fixing block is made of rubber. The rubber's good toughness and elasticity allow the guardrail to be more firmly fixed to the fixing groove.

[0007] According to the present invention, a motorcycle frame includes a connecting rod fixedly connected to the rear surface of the seat, with a backrest fixedly connected to one end of the connecting rod. This provides a comfortable riding device for the passenger and also forms a relatively safe seat structure with a child seat.

[0008] According to the present invention, a motorcycle frame includes a support frame whose upper surface is fixedly connected to the bottom surface of a cushion, and a support rod fixedly connected between the support frame and the license plate holder. This enhances the cushion's stability and also strengthens the connection between the license plate holder and the support frame.

[0009] According to the present invention, a motorcycle frame includes a guardrail in the shape of an inverted L. The end of the guardrail furthest from the frame body is fixedly connected to a handrail, and the diameter of the guardrail is larger than the diameter of the fixing groove. This design is used to combine the handrail and backrest to form a rectangular protective structure, facilitating the fixing groove to secure the guardrail.

[0010] According to the present invention, a motorcycle frame is provided, wherein the bottom end of the handrail is fixedly connected to a fixing rod, and the fixing rod abuts against the front surface of the seat. This is used to secure a child seat and ensure its stability with the seat.

[0011] According to the present invention, a motorcycle frame includes an anti-slip sleeve located on the upper surface of the handrail, and several reinforcing ribs, the diameter of which is smaller than the diameter of the handrail. This enhances the stability of the handrail.

[0012] According to the motorcycle frame described in this utility model, when the child seat is moved to the backrest position, the reinforcing ribs fit snugly against the upper surface of the backrest. This ensures that the child seat is in a relatively safe state even when not in use.

[0013] Beneficial effects: The rear surface of the motorcycle frame body uses mounting screws to install and fix the license plate in the mounting holes, so that the license plate is embedded in the mounting groove of the license plate holder, which helps to protect the license plate from damage and also solves the problem of the license plate being easily contaminated due to its low mounting position. The force between the fixing rod and the front surface of the seat, as well as the strong fixation of the guardrail into the fixing groove, provide different levels of safety protection for the child seat, and also eliminate the need to purchase an additional child seat, thus improving the practicality of the device. By rotating the child seat, the seat can be changed from "use state" to "storage state", which not only improves the flexibility of the device, but also saves space, facilitates daily use, and provides certain support for passengers.
