Description

Description: Embedded serial two-seat fully enclosed motorcycle body structure

The present invention relates to a power driven vehicle, and more particularly to a powered two-row two- or two-wheel motorcycle.

Background technique

The existing two-wheel (electric or fuel-engine-driven) motorcycle rides are mostly riding, which makes the vehicle have a compact structure and a light weight, but seriously ignores the safety of the driver and passenger. Nowadays, the two-wheeled car with power is light and fast, and its structural lateral instability is beyond the control of the driver. It causes more accidents. In the event of an accident, the vehicle cannot be driven. The protection provided by the passengers often causes the driver and passenger to fall down on the road and is crushed and killed by the vehicle. Some motorcycles have front and rear windshields and canopies, but they have limited effect in practical use. Basically, they can not overcome the above-mentioned defects. The safety of the tricycle is relatively high, but it has a large volume, loose structure and comfort. Poor shortcomings, not suitable for general household use.

Summary of the invention

The invention provides a fully enclosed vehicle body structure suitable for two-wheeled or three-wheeled motorcycles. The vehicle body adopts front and rear closed passenger compartments, so that the driver and passenger are changed from riding to seat, and the front and rear passenger compartments are provided. The full enveloping protection of the strong anti-strike structure improves the passive safety performance of the vehicle while improving the ride comfort of the driver and passenger. The safety concept is mainly: using side support wheels to reduce accidents caused by misoperation caused by vehicle instability; using fully enclosed vehicle body to reduce accidents caused by the impact of bad weather on drivers and passengers; using fully enclosed vehicle body to reduce due to vehicles Rolling accident caused by dumping caused by people falling down; also due to sufficient strength and the use of compression-resistant structure, the side body collision can change through the structure of the car body The shape absorbs most of the collision energy, and the seat acts as a secondary defense to protect the occupants. In addition, the wider body makes the vehicle crash more than the chassis height of most vehicles, so that they can only It is impossible to crush from it to ensure the safety of personnel. The embedded tandem two-seat fully enclosed motorcycle has a compact structure due to the new layout. The size of the vehicle is similar to that of a general two-wheeled motorcycle, and its own weight is also light.

In Fig. 6, 87 is the inner skin of the wall panel, which can be made of leather, plastic, etc. 88 is an inner liner board, which can be made of plastic sheet, steel plate and iron sheet; 89 is a cavity filling material in the wall panel, mainly for heat insulation, The function of noise reduction and collision buffering can be made of foamed plastic sponge or other equivalent materials; 90 is the outer skin of the siding, which can be made of steel plate, plastic or other composite materials; 91 is the anti-collision beam, and the inner cavity can also be Filled with lightweight and easy-to-form material; 92 is a cavity filling in the anti-collision bar, which can be filled with wax, foam plastic, etc., and the remaining components are the same as in Fig. 1.

In the embodiment of Fig. 7, 93 is a middle beam sliding track groove, the middle beam can be moved up and down under the control of the adjusting device, and can be locked at any height therein, 94 is a triangular reinforcing structure at the end of the middle beam, 95 is a front support The lower leg sleeve, the front seat right support leg 69 can slide up and down therein, 96 is the front seat base, and 97 is the front seat back fixing beam;

In the embodiment of Fig. 8, both the left main beam 55 and the right main beam 68 extend to the tail of the vehicle body, and quadrangular frames of equal size and shape are connected above the two, and the two quadrangular frames and the opposite sides of the main beam are connected with several groups. The horizontal crossbar constitutes the rear seat platform 38; the structure of the rear seat platform is also applicable to the two-wheeler scheme, but the rear wheel is installed between the left and right main beams by the suspension device.

The invention adopts a novel structural design, so that the vehicle body has a large space, and is suitable for various driving forms such as a fuel engine, a hybrid power, a fuel-electric drive, a pure electric drive, etc., regardless of which driving form is adopted, the vehicle body structure basically the same. The significance of the implementation of the present invention is to provide the rider of the vehicle with a better comfortable seating space and provide protection without increasing the length of the vehicle body and increasing the weight of the vehicle body. When using environmental protection schemes, it can effectively reduce carbon emissions and better meet the needs of future social security, environmental protection and efficient travel. Has good economic and social benefits.
