Abstract

A side-rollover protection skeleton for an electric vehicle includes a left antiroll frame (1), a right antiroll frame (2), at least one front cross beam (3), at least one back cross beam (4), and at least one upper cross beam (5). The left antiroll frame (1), the right antiroll frame (2), the front cross beam (3), the back cross beam (4), and the upper cross beam (5) are made of steel tubes. The left antiroll frame (1) and the right antiroll frame (2) are in the shape of enclosed frames and are connected with the front cross beam (3), the back cross beam (4) and the upper cross beam (5) to form a cage structure. The side-rollover protection skeleton for the electric vehicle is simple in structure, safe and reliable. When a side rollover happens, the left antiroll frame and the right antiroll frame are supported by the front cross beam, the back cross beam, and the upper cross beam, and the collision energy is distributed to the whole cage, thus keeping the cage structure from deforming as possible, and protecting the safety of the passengers inside the cage effectively. The side-rollover protection skeleton can be widely used for electric off-road vehicle, ATV, hunting vehicle and golf cart etc..

Description

Description Book Electric vehicle rollover protection skeleton

Technical field

The utility model relates to an electric vehicle protection structure, in particular to a side-turn protection skeleton. Background technique

Usually, when the car is turned over, the side structure of the vehicle body is relatively thin, and it is easy to deform from the upper part or the side part, and the internal space is squeezed, and the internal occupant is directly squeezed, causing great damage to the personnel, so in order to improve the occupant For safety, it is necessary to provide a car frame structure that enhances the strength of the side structure of the car. Utility model content

The problem to be solved by the utility model is to provide an electric vehicle rollover protection skeleton with simple structure, safety and reliability. The technical solution adopted by the utility model is as follows: The electric vehicle rollover protection skeleton comprises a left roll cage, a right roll cage, one or more front beams, one or more rear beams, one or more upper beams, preferably the left The roll cage, the right roll cage, the front beam, the rear beam and the upper beam are made of steel pipes, and the left roll cage and the right roll cage are closed and framed, and are connected by a front beam, a rear beam and an upper beam. A frame structure, and the left roll cage and the right roll cage combined with the upper beam can also be installed with a canopy.

In the above solution, preferably, the left roll cage and the lower side of the rear side of the right roll cage are respectively provided with a lower link inwardly to be integrally connected with the frame, thereby increasing the firmness.

In the above solution, preferably, the left roll cage and the right roll cage are respectively provided with handles for the personnel. Pull holding, _t further enhance the safety of the present invention has the advantages that: the present invention is simple, safe, reliable, integrally form a frame structure, when the automobile rollover occurs, the front cross member, rear cross member, the lateral supports The left roll cage and the right roll cage simultaneously divert the collision energy to the whole frame, and try to keep the frame structure from deformation or deformation, which effectively protects the passengers inside the frame. It can be widely used in electric off-road vehicles, ATVs, Hunting cars, golf carts, etc. DRAWINGS

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

1 is a schematic view of the overall structure of a specific embodiment of the present invention;

2 is a schematic top plan view of a specific embodiment of the present invention;

3 is a side view showing a schematic view of a specific embodiment of the present invention;

FIG. 5 is a side view structural view of the embodiment of the present invention after being mounted on a chassis of an automobile. FIG. detailed description

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, the electric vehicle rollover protection skeleton includes a left roll cage 1, a right roll cage 2, a front beam 3, a rear beam 4, and two upper beams 5 The left roll cage 1, the right roll cage 2, the front cross member 3, the rear cross member 4, and the upper cross member 5 are made of steel pipes, and of course, can also be made of steel bars, and the left roll cage 1 and the right roll cage 2 are closed. In the frame shape, the front cross member 3, the rear cross member 4, and the upper cross member 5 are connected to form a frame structure, and the left anti-roll frame 1 and the right anti-roll frame 2 are respectively provided with a lower link 6 inwardly to pass through the seat. The backrest bracket is integrated with the frame to further increase the firmness for the convenience of passengers. Description

Hold, left roll cage 1, right roll cage 2 also has a handle 7 on the top.

When mounted on the vehicle body, as shown in Figure 5, the electric vehicle rollover protection frame can be connected to the bottom of the left roll cage 1 and the right roll cage 2 by bolts. At this time, the left roll cage 1, the right roll guard The frame 2 can also be mounted with the top beam 5, the left roll cage 1, the front roll cage 2 can also be equipped with a front windshield 9 at the front, and the lower link 6 is also connected by the back bracket 1 1 of the back of the seat 10. Go to the frame.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. The present invention may be modified or equivalently replaced without departing from the spirit and technical features of the present invention. It is intended to be covered by the scope of the claims of the invention.
