Description

Technical Field

[0001] This utility model relates to the field of vehicle frames, and more particularly to non-load-bearing SUV pickup truck frames. Background Technology

[0002] A non-load-bearing frame refers to a vehicle support system that uses an independent chassis structure. Its core characteristic is that the body and chassis are designed separately. This type of frame is usually welded from high-strength steel beams to form a trapezoidal or box-shaped frame structure, and is particularly common in SUVs and pickup trucks. Its main function is to provide excellent load-bearing capacity and terrain adaptability. Through the independent beam structure, it effectively disperses road impact forces, ensuring the vehicle's torsional rigidity and overall stability under complex road conditions.

[0003] A Chinese patent document, CN202420286160.6, describes a non-load-bearing vehicle frame, belonging to the field of automotive frame technology. It solves the problem of poor stability in the connection between crossbeams and longitudinal beams in existing non-load-bearing frames. This non-load-bearing frame includes two longitudinal beams and several crossbeams located between the two longitudinal beams. The longitudinal beams are made of channel steel, with the slots of the two longitudinal beams facing each other. The left end of the crossbeam is inserted into the slot of the left longitudinal beam, and the right end of the crossbeam is inserted into the slot of the right longitudinal beam. Each longitudinal and crossbeam has an upper side, a lower side, and a vertical side connecting the upper and lower sides. The upper side of the crossbeam is connected to the upper side of the longitudinal beam by fasteners, and the lower side of the crossbeam is connected to the lower side of the longitudinal beam by fasteners. The vertical side of the crossbeam is connected to the longitudinal beam by a connecting structure. The connection structure, linking the vertical side of the crossbeam to the longitudinal beam, improves the stability of the connection between the crossbeam and longitudinal beam. The fasteners are screws or rivets.

[0004] However, the above-mentioned patent has certain defects in use. Because the connection between the crossbeam and the longitudinal beam is easily affected by stress concentration, the entire frame will shake when encountering complex road conditions. There is not enough buffer between the crossbeam and the longitudinal beam, resulting in a poor driving experience for the driver.

[0005] To address these issues, a non-load-bearing SUV pickup truck frame is proposed. Utility Model Content

[0006] In order to overcome the problem that the connection between the crossbeam and the longitudinal beam in the existing technology is prone to stress concentration and the driver's driving experience is poor when encountering bumpy roads, this utility model provides a non-load-bearing SUV pickup truck frame.

[0007] This utility model is achieved using the following technical solution:

[0008] A non-load-bearing SUV pickup truck frame includes a first crossbeam and two parallel second crossbeams. Both ends of the inner side of the first and second crossbeams are provided with mounting areas. A first spring is embedded in the mounting area and connected to a first compression plate. Tripods are symmetrically arranged on the mounting areas, and the connecting end of the tripods is provided with a limiting groove.

The two ends of the U-shaped bolt are respectively fixed to the two sides of the connector. The two ends of the U-shaped bolt are provided with second nuts to fasten to the connector.

[0013] As a preferred embodiment of this utility model, the connector is provided with a sliding groove on one side, the sliding groove is movably connected to the second contact, the second contact can slide along the sliding groove, and an installation port is provided at the opening of the sliding groove.

[0014] As a preferred embodiment of this utility model, a mounting component matching the mounting port is provided on one side of the connector, and a movable bolt is detachably provided on the mounting component.

[0036] Two connectors 4 are symmetrically arranged on the inner sides of the first crossbeam 100 and the second crossbeam 200. The inner sides of the first crossbeam 100 and the second crossbeam 200 are correspondingly installed. Each pair of connectors 4 forms a group, and at least one group is provided.
