technical field

The utility model relates to a vehicle frame in the field of vehicles, in particular to a dual-energy general-purpose functional vehicle frame that can be used for gasoline vehicles and electric vehicles.

Background technique

At present, the mileage of electric vehicles is relatively short, and the charging facilities are not perfect enough. Electric vehicles can only be used as short-distance transportation. Gasoline vehicles are more convenient for long-distance travel or continuous driving for longer mileage.

Since the electric vehicle market is not yet stable and mature, the investment cost and risk of developing a dedicated electric vehicle frame are high. If the existing fuel car is replaced by an electric car after removing the engine and other assemblies, the refitting process is not only troublesome, but also reduces the performance of the original frame to a certain extent, and also causes great hidden dangers in terms of safety. It can be seen that there is an obvious lack of interchangeability between the traditional fuel vehicle frame and the pure electric vehicle frame. Therefore, the development of a dual-energy general-purpose functional frame can take into account the layout and installation of gasoline or electric vehicle parts, improve the flexibility of vehicle production, greatly reduce the cost of enterprise design and development and mold development costs, and at the same time satisfy the Meet customers' demand for gasoline vehicles or pure electric vehicles.

Utility model content

And without any modification to the vehicle frame, it overcomes the shortcomings of the traditional vehicle frame powertrain interchangeability. It not only retains the advantages of traditional gasoline vehicles, but also meets the needs of some customers for pure electric vehicles. It is a dual-energy universal functional frame.

The solution of the present utility model is like this:

A dual-energy universal function vehicle frame, including a vehicle frame formed by connecting left and right longitudinal beams, a front beam and a rear beam, characterized in that: the longitudinal beams are bent, forming two mounting surfaces with a low front and a high rear The longitudinal beam on the front mounting surface is fixed with a mounting seat, and the rear beam at the front end of the rear mounting surface is fixed with a gearbox mounting seat and a power battery assembly mounting seat with a flexible connection structure. An installation supporting part for installing the gearbox or installing the battery assembly is formed between the brackets on the surface, and is used for installing the gearbox or installing the battery assembly.

A more specific technical solution also includes: the gearbox mounting seat is located in the middle of the front end beam, and the power battery assembly assembly uses two mounting seats, which are respectively located on both sides of the gearbox mounting seat.

Further: the above-mentioned movable connection structure for fixing the gearbox mounting seat adopts a bolt connection structure, and the gearbox mounting seat is fixed by bolts.

Further: the movable connection structure for fixing the mounting seat of the power battery pack adopts a bolt connection structure, and the mounting seat of the power battery pack is fixed with bolts.

Further: the longitudinal beam is bent into a right-angle shape.

Further: the mounting seats for fixing the left and right longitudinal beams are left and right symmetrical installations.

The utility model has the advantage that the space in the middle of the longitudinal beam of the vehicle frame and the installed seat can be well compatible with the installation of the gasoline vehicle engine and gearbox assembly or the power battery pack assembly of the electric vehicle, and the rear part of the vehicle frame can be installed according to the gasoline vehicle. Or electric vehicles can be equipped with rear axles with different requirements, and the interchange between gasoline vehicles and pure electric vehicles can be realized without any changes to the frame, which improves the flexibility of vehicle production and greatly reduces the cost of enterprise design and development and mold development At the same time, it also satisfies customers' needs for gasoline vehicles or pure electric vehicles.
