Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a four-wheeled buggy used for carrying luggage on a ranch, farmland, wasteland, etc., and particularly has a round handle operated in a sitting posture. The present invention relates to a body frame of a four-wheel buggy.

(Prior Art) In recent years, three- and four-wheeled buggies have been developed as small vehicles suitable for traveling on ranches, farm lands, wastelands, and the like. These three- and four-wheeled buggies are driven in a riding posture like a motorcycle. As a prior art document, there is, for example, Japanese Utility Model Application Laid-Open No. 61-66089.

This riding type buggy car is difficult to get on and off, and runs on rough ranches, farm lands, and wasteland, etc., so that the operation of the bar handle is heavy, and tired when running for a long time. Furthermore, the luggage can only be loaded slightly and cannot be carried on board.

Therefore, recently, a four-wheeled buggy having a round handle driven in a sitting posture has been developed. In the case of this four-wheel buggy vehicle, the entire drive device is disposed at the rear of the vehicle, and the steering device is disposed at the front of the vehicle.

(Problems to be Solved by the Invention) However, in the four-wheeled buggy driven in the above-described sitting posture, the front portion of the seat on which the driver and the passenger are seated does not hinder driving and is easy to get on and off. The upper part of the flat floor is a complete space, and the lower part of the flat floor travels while bounding in a place with severe unevenness, so the frame must have sufficient strength, and the lower part of the frame It is required that the member does not protrude. Therefore, it is necessary to reinforce the frame. In addition, a cable for an operation system for starting, igniting, controlling the output, and stopping the driving device in the rear of the vehicle at a driver's seat, and a wire for an electric system for charging, lighting, etc. It is necessary to secure a wiring path such as this.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a body frame of a seated four-wheeled buggy having sufficient strength and having a wiring passage in a main frame so that various cables and electric wires are not damaged.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the body frame of the seated four-wheeled buggy according to the present invention is composed of a main frame and a pair of left and right frame members provided at a required interval in the longitudinal direction. The cross pipes are combined into a flat underframe shape, and the front ends of the two right and left frame members are bent symmetrically inward toward the inner side to make the width narrower, and the front ends are close to the narrower frame members. The two inlet and outlet pipes of the radiator are arranged in parallel and in the same plane as reinforcing materials and extend rearward, and the middle is fixed to each cross pipe of the main frame, and the two inlet and outlet pipes of the main frame are fixed. A wiring space is formed therebetween, and a wiring guide is fixed through the cross pipe in the wiring space.

(Operation) As described above, the body frame of the present invention is configured such that the introduction pipe and the extraction pipe of the radiator are fixed through the cross pipes of the main frame so that the main frame is reinforced and the cooling water flows from the front to the rear. No special cooling water pipe is required, and when running on uneven terrain, even if strong vibration or impact is applied, it is difficult for the inlet pipe and outlet pipe to directly hit obstacles, and the risk of pipe breakage is extremely low. In addition, despite the long cooling water passage, since it is integrated with the cross pipe, durability can be secured without special consideration. In addition, since a wiring path is secured from the front to the rear in the wiring space between the two inlet pipes and the outlet pipe within the thickness of the main frame, the cable for the operation system and the electric wire for the electric system can be used. It can be stably installed without protruding above the floor of the driver's seat or below the body frame, and can prevent damage when a four-wheel buggy runs while bounding in a highly uneven place. . Furthermore, since the main frame is reinforced by the radiator inlet pipe and outlet pipe as described above, the strength of the vehicle body frame is improved without increasing the number of components of the main frame.
