Description

A New Type of Light Passenger Cage Body Structure

technical field

The utility model relates to the manufacturing field of passenger cars and parts thereof, more specifically a novel light passenger cage body structure.

Background technique

Existing light buses generally adopt a flat-head radial structure, which is welded by square tubes and iron castings, which is heavy and costly. At the same time, the body frame is difficult to reach a balanced state because it is directly welded to the chassis frame of the car; another On the one hand, the pressure-bearing capacity of the top and side of most car bodies is weak, and they cannot fully absorb energy and transmit force, resulting in relatively low crash performance of the car body.

Utility model content

The utility model discloses a novel light passenger cage body structure, and its main purpose is to overcome the above-mentioned deficiencies and shortcomings existing in the prior art.

The technical scheme that the utility model adopts is as follows:

A new light passenger cage body structure, including a long-headed body, the body is provided with a body frame, the body frame includes a water tank frame, a main anti-collision beam, a secondary anti-collision beam, a water tank bracket, a water tank Columns, vehicle body columns and front windshield beams, the water tank frame, main anti-collision beams, auxiliary anti-collision beams, and water tank brackets form the front wall of the vehicle body frame with water tank columns, and a connecting beam is arranged on the vehicle body columns and the vehicle body column extension plate, the front wall of the vehicle body is connected to the vehicle body column and the front windshield cross beam through the connecting beam and the vehicle body column extension plate, and forms a cage body structure surrounded by a closed skeleton.

Furthermore, there are two secondary anti-collision beams, which are respectively symmetrically arranged on the left and right sides of the front area of the body frame.

Furthermore, the secondary anti-collision beams are arranged in an oblique connection.

Furthermore, the upper body frame body of the front windshield beam is provided with a vehicle roof frame, and the vehicle roof frame is connected with the front windshield beam to form a vehicle roof.

Furthermore, there are two vehicle body columns, which are respectively symmetrically arranged on the left and right sides of the vehicle body framework.

Can know that by above-mentioned description to the utility model, compared with existing technology, the advantage of the utility model is:

1. This utility model abandons the existing flat-headed body structure, and designs the body structure as a long-headed structure. At the same time, it adopts the principle of cage structure to optimize the design of the top structure of the body and the column area, and improve the stability of the body when it rolls over and the top is under pressure. The high compressive capacity makes the body structure more reasonable and improves the collision ability of the body.

2. The vehicle body of the present invention optimizes the design of the longitudinal beam area, so that the energy absorption capacity of the vehicle body is improved. At the same time, the structural channel design for force transmission is adopted to further improve the collision performance and safety of the vehicle body.

3. The utility model has simple and practical structure, novel and reasonable design, and has high practical application and popularization value.

Detailed ways

The specific embodiment of the present utility model will be further described below with reference to the accompanying drawings.

As shown in Figure 1, a new light passenger cage body structure includes a long-headed body 1, on which a body frame body is provided, and the body frame body includes a water tank frame 2, a main anti-collision beam 3, Auxiliary anti-collision beam 4, water tank bracket 5, water tank column 6, vehicle body column 7 and front windshield beam 8, said water tank frame 2, main anti-collision beam 3, auxiliary anti-collision beam 4, water tank bracket 5 and water tank The column 6 constitutes the front wall of the vehicle body frame, and the vehicle body column 7 is provided with a connecting beam 9 and a vehicle body column extension plate 10, and the vehicle body front wall is connected to the vehicle body column through the connecting beam 9 and the vehicle body column extension plate 10. 7 and the front windshield beam 8, and form a cage body structure surrounded by a closed skeleton.

Furthermore, there are two secondary anti-collision beams 4, which are respectively symmetrically arranged on the left and right sides of the front area of the vehicle body framework.

Furthermore, the secondary anti-collision beams 4 are arranged in an oblique connection.

Furthermore, the upper body frame body of the front windshield beam 8 is provided with a vehicle body roof frame 10, and the vehicle body roof frame 11 is connected with the front windshield beam 8 to form a vehicle body roof.

Furthermore, there are two vehicle body pillars 7, which are respectively symmetrically arranged on the left and right sides of the vehicle body framework.

The utility model abandons the existing flat-headed body structure, designs the body structure as a long-headed structure, and adopts the cage structure principle to optimize the design of the top structure of the body and the column area, so as to improve the body's rollover and the resistance of the top under pressure. Compression ability makes the body structure more reasonable and improves the collision ability of the body.

The car body of the utility model optimizes the design of the longitudinal beam area, so that the energy absorption capacity of the car body is improved. At the same time, the structure channel design for force transmission is adopted to further improve the collision performance and safety of the car body. The utility model has simple and practical structure, novel and reasonable design, and has high practical application and popularization value.

The above is only the specific implementation of the utility model, but the design concept of the utility model is not limited thereto, and any insubstantial improvement of the utility model by using this concept should be an act of violating the protection scope of the utility model.
