Technical Field

[0001] The utility model relates to the technical field of magnesium alloys, and particularly relates to a magnesium alloy vehicle frame and an internal strengthening structure thereof. Background Art

[0002] At present, the body of a scooter is mostly assembled by connecting a front vehicle frame, a middle vehicle frame and a rear vehicle frame made of metal. The front vehicle frame, the middle vehicle frame and the rear vehicle frame are mostly welded by steel materials such as steel pipes and steel plates. The connections between the front vehicle frame, the middle vehicle frame and the rear vehicle frame are mostly welded and bolted. The front vehicle frame of the scooter supports the front wheels and the steersman. The middle vehicle frame of the scooter occupies the main part of the total body length and supports the seat tube. The rear vehicle frame of the scooter supports the motor and the rear wheels. The existing scooters are widely used and have the advantage of being convenient for the elderly to operate. At present, for the scooters on the market, the body is made of steel structure, and the density of steel is relatively large. Therefore, most of them have the problem that the overall weight of the scooter is relatively large and it is not convenient to carry. For example, the patent with the patent number CN217320641U3 discloses a frame structure of a scooter welded by magnesium alloy. The patent includes a front vehicle frame, the rear side of the front vehicle frame is movably connected with a middle vehicle frame, the rear side of the middle vehicle frame is movably installed with a rear vehicle frame, a fixing bolt is movably installed inside the front vehicle frame, a welding mechanism is fixedly installed on the top of the rear vehicle frame, the welding mechanism includes a first magnesium alloy rectangular tube, a first round tube, a vehicle frame beam, a magnesium alloy profile, a seat tube, a second magnesium alloy rectangular tube and a second round tube, the front vehicle frame includes a first magnesium alloy rectangular tube, and a first round tube is fixedly installed on the rear side of the first magnesium alloy rectangular tube. By using magnesium alloy material in the utility model, the density of magnesium alloy is 1.8 g / cm3, and the density of steel is 7.8 g / cm3. The specific strength of carbon steel is 66 N*m / kg, while the specific strength of magnesium alloy is 154 N*m / kg. Using magnesium alloy makes the vehicle body lighter, and connecting the front vehicle frame, the middle vehicle frame and the rear vehicle frame by welding makes the connection between the front vehicle frame, the middle vehicle frame and the rear vehicle frame more stable, so as to achieve the effect of weight reduction and strength enhancement of the structure.

[0003] Although the above patent replaces the common steel structure with magnesium alloy, when the magnesium alloy is impacted during use, it may still cause deformation.

[0004] Therefore, the technical personnel in the field provide a magnesium alloy vehicle frame and an internal strengthening structure to solve the problems raised in the above background art. Content of the Utility Model
