Description

Passenger protecting structure for multipurpose cart

The present invention relates to a multi-purpose vehicle occupant protection structure, and more specifically, a so-called roll over protective structure for protecting the occupant (roll over protective structure) frame structure to connect the front and rear frames and these, and the rear frame is connected to the vehicle body By separating and constructing the connection as a connection method, by using pipe joint method or angle connection method, the assembling and dismantling of the frame is basically done quickly and easily, as well as the space required for disassembly and shipment, which reduces shipping costs. The manufacturing cost is reduced according to the simple shape production, and the frame structure also includes the vehicle body so that the side structure is a four-link structure, so that the frame pivot can be appropriately rotated at the center of rotation of the frame during front and rear shocks such as rapid starting and sudden braking. Increase the reliability of the product by improving the rigidity by absorbing the shock A passenger protection structure for a multi-purpose carrier vehicle is provided.

In general, a car can be divided into a car body, a chassis and a frame, and the car body is largely divided into an engine compartment, a passenger compartment, and a trunk.

Cars are often classified in the form of car bodies, and the basic structure of a car body can be divided into a frame type that separates the car body and the frame, and a monocoque that the body and the frame are united.

Frame-type car body is made of a solid steel structure is durable but has the disadvantage that the overall weight is heavy, the integral structure car body has the advantage of dispersing the impact applied from the outside to the entire body.

In addition, the chassis generally refers to the rest of the vehicle except for the vehicle body, and refers to the main engine such as a power transmission device, a steering device, a suspension device, a braking device, as well as a car engine that is the driving force for driving.

And, the frame acts like a skeleton of a car that allows these various devices to take place.

On the other hand, among the vehicles having such a basic structure is a vehicle used in a plastic house cultivation complex, such as a rural area, there is a multi-purpose transport vehicle for transporting agricultural products or farm equipment necessary for various farming.

In addition, a so-called roll over protective structure frame structure is provided around the passenger seat including the driver's seat of the multipurpose transport vehicle to protect the occupant when the vehicle is overturned.

However, such a passenger protection structure of the prior art simply wraps around the passenger seat, so that the entire frame structure is an integral structure. It requires a lot of shipping cost, and the production cost increases due to the integrated structure method, and also increases the production cost, and also accumulates long-term fatigue due to the load on each bending part of the integrated connection structure during front and rear shocks such as rapid starting and sudden braking of the vehicle. This leads to a weakening of the rigidity, resulting in a shortened product life.

The present invention has been made to solve such a problem, the so-called roll over protective structure for protecting the occupant (roll over protective structure) frame structure is separated by a connection connecting the front and rear frames and the front and rear frames connected to the vehicle body By using the pipe joint method or the angle connection method, the assembly and dismantling of the frame can be done quickly and easily, and the shipping cost is reduced due to the small space required for disassembly and shipment. The manufacturing cost is reduced, and the frame structure also includes the vehicle body so that the side structure is a four-link structure, so that the shock is properly absorbed from the central axis of rotation of the frame when the vehicle suddenly starts or stops, such as sudden braking or sudden braking. To increase the reliability of the product according to the improvement of rigidity. Its purpose is to provide a rider protection structure for a multi-purpose vehicle.

In order to achieve the above object, the multi-purpose vehicle occupant protection structure according to the present invention has a pair of upper and lower extension poles having a lower end connected to both front sides of the vehicle body and having an upper end extending upward, and a pair of upper and lower extension poles. Front frame having a left and right extension connecting the upper end; The rear having a pair of upper and lower extension poles whose lower ends are connected and fixed to both rear sides of the vehicle body spaced apart from the front frame by a predetermined distance, and the upper end extends upward, and left and right extension poles connecting the upper ends of the pair of upper and lower extensions. frame; And a connecting rod connecting the front and rear frames.

In addition, in the passenger protection structure for a multi-purpose transport vehicle according to the present invention, in the connection structure of the upper and lower extension of the front frame and the vehicle body, the corresponding connection portion of the vehicle body is a square tube structure, the fastening hole is formed on one side thereof, corresponding to this A connection angle of a right angle bending plate shape having a through hole formed to be in line with the fastening hole is provided at the lower end of the upper and lower extension, which is fastened by a separate fastener while the inner side of the connection angle is in close contact with the outer surface of the vehicle body. It is desirable to be fixed.

In addition, in the occupant protection structure for a multi-purpose transport vehicle according to the present invention, the corresponding connection portion of the vehicle body is inclined in the inward direction of the vehicle body, and the connecting angle of the vertical extension corresponding thereto is also inclined at the same angle so that the frictional force between the contact surface when connecting to each other It is preferable that this is formed to minimize the vertical load of the front frame.

In addition, in the occupant protection structure for a multi-purpose transport vehicle according to the present invention, it is preferable that a stopper is further provided to prevent the connection angle from sliding downward in a lower portion adjacent to a corresponding connection portion of the vehicle body to which the connection angle is coupled.

In addition, in the passenger protection structure for a multi-purpose transport vehicle according to the present invention, the connecting structure between the upper and lower extension poles and the vehicle body of the rear frame, the upper and lower extension poles have a cylindrical structure, through-holes are formed at the lower end thereof, A connection part of a circular tube structure having a through-hole formed to lie on the same line as the through-hole is provided, and the upper and lower extension poles may be covered by an outer circumferential surface of the connection part to be fastened and fixed by a separate fastener.

In addition, in the passenger protection structure for a multi-purpose transport vehicle according to the present invention, the front and rear frame and the connection structure of the connecting rod, the connecting rod is a cylindrical structure, through holes are formed at both ends thereof, and corresponding to the front and rear frame Connection portions of a cylindrical structure having through holes formed to lie on the same line as the through holes are provided on the connection portions, and both ends of the connection table may be covered by outer peripheral surfaces of the connection portions to be fastened and secured by separate fasteners.
