Description

A skeleton structure for installing school bus seats

technical field

The utility model relates to an improvement of a school body structure, in particular to a skeleton structure for installing school bus seats.

Background technique

For now, existing buses generally include longitudinal beams, body floors, and seats. Since the size and quantity of bus seats are fixed, when it needs to be converted into a school bus, the specifications of the seats are often directly changed and placed directly on the body floor. superior. Since the seat and the body floor often need to be firmly combined, it is necessary to frequently open holes in the body floor for locking. However, since the passenger car may be refitted many times during use, if the body floor is frequently drilled, the strength of the body floor will be reduced and cracks will occur, which will bring great safety hazards to the driving of the vehicle.

Utility model content

The utility model provides a skeleton structure used for installing school bus seats, and its main purpose is to overcome the defects of reduced body floor strength and potential safety hazards in existing school bus refitting.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A skeleton structure for installing a school bus seat, comprising a longitudinal beam, a body floor, a plurality of school bus seats, a guardrail for supporting the school bus seat and a skeleton unit, the bottom of the skeleton unit passes through the body floor lock Attached to the longitudinal beam, the top of the skeleton unit is provided with a plurality of assembly holes, and the school bus seat and guardrail are locked and attached to the skeleton unit through the assembly holes.

Further, the skeleton unit is composed of a plurality of longitudinally arranged square steels and a plurality of transversely arranged channel steels connected vertically to each other.

Further, the school bus seat and guardrail are locked on the channel steel.

Further, the square steel lock is attached to the vehicle body floor.

Further, the skeleton unit is sequentially divided into a front installation skeleton, a middle installation skeleton and a rear installation skeleton from front to back.

Further, the channel steel is Q345B channel steel.

Further, the Q345B channel steel is welded to the square steel.

Compared with prior art, the beneficial effect that the utility model produces is:

1. The utility model has simple structure and strong practicability. A skeleton unit is added to the basic body floor to provide installation points for school bus seats and guardrails, and to reinforce local strength.

2. In the present utility model, the school bus seat is locked by setting a skeleton unit, and the skeleton unit is locked to the longitudinal beam through the vehicle body floor, so that only the skeleton unit and the The connection form of the school bus seat does not require mechanical processing of the body floor, so it can be as convenient as possible to change the number and specifications of the school bus seat on the premise of maintaining the overall strength and service life of the body floor without affecting the interior decoration of the model. Retrofitting offers great convenience.

3. In the present utility model, since the whole floor of the vehicle body is non-planar, the skeleton units need to be adjusted and corresponded in local coordination. Since the entire skeleton unit is too large, in order to ensure the assembly process, it is divided into three sections for processing. Seats and guardrails are locked to the frame, and the frame is locked to the longitudinal beam through the body floor, so the force of the school bus seat and guardrail can be transmitted to the body longitudinal beam, and the school bus seat is locked in a 5mm thick groove On steel, the strength has been verified by the school bus seat frame test.

detailed description

The specific embodiment of the utility model is described below with reference to accompanying drawing.

Refer to Figure 1, Figure 2 and Figure 3. A skeleton structure 1 for installing a school bus seat, comprising a longitudinal beam, a body floor 2, a plurality of school bus seats, a guardrail for supporting the school bus seat and a skeleton unit 3, the bottom of the skeleton unit 3 passes through the The vehicle body floor 2 is locked to the longitudinal beam, and the top of the frame unit 3 is provided with a plurality of assembly holes 30 , and the school bus seat and guardrail are locked to the frame unit 3 through the assembly holes 30 . In this embodiment, a skeleton unit 3 is added to the basic body floor 2 to provide installation points for school bus seats and guardrails, and to reinforce local strength. In addition, the school bus seat is locked by setting a frame unit 3, and the frame unit 3 is locked to the longitudinal beam through the body floor 2, so that only the frame unit 3 and the school bus seat need to be changed in the refitting process. The connection form of the seat does not need to carry out mechanical processing on the body floor 2, so it can be as convenient as possible to change the number and specifications of the school bus seats on the premise of keeping the overall strength and service life of the body floor 2 unaffected, and to give the vehicle interior decoration Retrofitting offers great convenience.

Refer to Figure 1, Figure 2 and Figure 3. The skeleton unit 3 is composed of a plurality of longitudinally arranged square steels 31 and a plurality of transversely arranged channel steels 32 vertically connected to each other. The school bus seat and guardrail are locked on the channel steel 32 . The square steel 31 is locked on the vehicle body floor 2 . Described channel steel 32 is Q345B channel steel 32. The Q345B channel steel 32 is welded to the square steel 31.

Refer to Figure 1, Figure 2 and Figure 3. The frame unit 3 is sequentially divided into a front mounting frame 33 , a middle mounting frame 34 and a rear mounting frame 35 from front to back. Since the body floor 2 is overall non-planar, the skeleton unit 3 needs to be adjusted and corresponding in local coordination. Since the entire skeleton unit 3 is too large, in order to ensure the assembly process, it is divided into three sections for processing. Seats and guardrails are locked to the frame, and the frame is locked to the longitudinal beam through the body floor 2, so the force of the school bus seat and guardrail can be transmitted to the body longitudinal beam, and the school bus seat is locked on the 5mm thick On the channel steel 32, the strength has been verified by the school bus seat frame test.

Wherein the front mounting frame 33 is mainly used for fixing the nursing seat and the left and right guardrails, the front mounting frame is locked on the vehicle body, and the rear mounting point is locked together with the middle mounting frame.

The middle installation frame 34 arranges the first row, the second row of seats and a single guardrail. The middle mounting frame is locked to the frame longitudinal beam through the mounting points on the three longitudinal square steels below, and the front three mounting points of the middle mounting frame are locked to the vehicle body together with the front mounting frame.

The rear mounting frame 35 arranges the third row, the fourth row of seats, the fifth row of seats and two single-person guardrails. The rear mounting frame is locked to the frame rails through the mounting points on the three longitudinal square steels below.

The above is only a specific embodiment of the utility model, but the design concept of the utility model is not limited thereto, and any non-substantial modification of the utility model by using this concept should be an act of violating the protection scope of the utility model.
