Description

Car body reinforcement structure

This creation is a car body reinforcement structure, especially a car body reinforcement structure applied to the body structure of a coach.

Due to the large passenger capacity and high riding convenience, today's coaches have become a common means of transportation between scenic spots and cities. People often take buses to visit scenic spots or commute between cities. Therefore, in order to protect the bus The safety of passengers in passenger cars, the strength of the body structure of coaches must comply with safety regulations.

The body structure of today's coaches includes two spaced-apart side wall frames and a top frame provided on the top of the side wall frames. The two side wall frames are formed with a plurality of spaced straight beams and two adjacent straight beams. Viewing windows will be arranged between the two, and the top frame has a plurality of cross beams in the shape of a letter and spaced apart. The opposite ends of some of the beams are overlapped on the tops of the straight beams of the two side surrounding frames.

However, due to the high center of gravity of the bus body structure of the coach, it is easy to overturn when traveling on curves or uneven roads, resulting in the side force of the car body structure being concentrated on the beams where the straight beams overlap each other At the curved part, if the structural strength of the beam is insufficient, the beam is likely to be deformed or even broken, so there are safety concerns.

The main purpose of this creation is to provide a car body reinforcement structure, hoping to improve the problem of insufficient structural strength of the current car body structure.

In order to achieve the purpose of pre-disclosure, the car body reinforcement structure of this creation includes: The two side enclosure frameworks are arranged at intervals relative to each other, each side enclosure framework has a plurality of straight beams arranged at intervals, and a window frame space is formed between two adjacent straight beams; A top frame is spanned on the two side surrounding frames. The top frame has a plurality of main beams and a plurality of auxiliary beams in a zigzag shape. The opposite ends of the plurality of main beams form a curved arc segment and are connected to the two Corresponding to the position of the straight beams of the side frame, the plural auxiliary beams are respectively arranged between two adjacent main beams; and Most of the reinforcing pieces are respectively arranged on the plurality of main beams of the top skeleton, and are respectively located inside the curved arc sections of the plurality of main beams.

The car body reinforcement structure of the present invention is applied to the body structure of a coach, wherein the car body reinforcement structure mainly uses the plurality of reinforcement pieces respectively provided on the main beam, thereby enhancing the main beam of the top frame The structural strength, so when the top frame is subjected to external impact, the reinforcing pieces can respectively distribute the stresses on the curved section of the corresponding main beam, thereby avoiding deformation or fracture of the main beam.

Please refer to FIG. 1 to FIG. 3, which is a preferred embodiment of the vehicle body reinforcement structure, which includes two side frame 10, a top frame 20 and a plurality of reinforcement sheets 30.

As shown in FIG. 1, the two side enclosure frameworks 10 are spaced relative to each other, and each side enclosure framework 10 has a plurality of straight beams 11 spaced apart, and a window frame space 12 is formed between two adjacent straight beams 11.

As shown in FIGS. 1 and 2, the top skeleton 20 is spanned on the two side surrounding skeletons 10. The top skeleton 20 has a plurality of main beams 21 and a plurality of auxiliary beams 22 in a zigzag shape. A curved arc section 211 is formed at the opposite ends and corresponds to the position of the straight beam 11 of the two side surrounding frames 10. The plurality of auxiliary beams 22 are respectively disposed between the two adjacent main beams 21.

As shown in FIGS. 2 and 3, the plurality of reinforcing pieces 30 are respectively disposed on the plurality of main beams 21 of the top frame 20 and are respectively located inside the curved arc sections 211 of the plurality of main beams 21.

Among them, in the preferred embodiment of the vehicle body reinforcement structure of the present invention, the straight beam 11, the main beam 21 and the auxiliary beam 22 are all square rods.

This car body reinforcement structure is applied to the bus body structure of a bus. The car body reinforcement structure mainly uses the plurality of reinforcement pieces 30 respectively provided on the main cross member 21. When the car body of the bus is subjected to external impact, the During the loading of the side frame 10 and the top frame 20, the stress will not concentrate on the curved arc section 211 of the main beam 21 of the top frame 20, thereby enhancing the structure of the main beam 21 of the top frame 20 Strength, thereby avoiding deformation or breakage of the main cross member 21, so that the strength of the body structure of the coach meets the regulations of the regulations to ensure the safety of passengers.

In summary, the car body reinforcement structure can improve the structural strength of the main beam 21 of the top frame 20 by the reinforcement sheet 30, and can separately distribute the locations of the curved arc sections 211 of the corresponding main beam 21 Under the stress, in order to comply with safety regulations.
