Background
At present, an automobile is a common transportation tool in daily life of people, and with the improvement of living standard, more and more families around the world select outdoor vacation after work, which accelerates the development of domestic and foreign trailer industry. Conventional trailers are generally welded by steel frames, and articles such as boats, motorcycles or luggage can be placed on the trailers according to requirements. However, the conventional trailer has too large volume to meet the requirement of portable transportation when not in use. Therefore, how to design a trailer technology which is convenient to carry is a technical problem to be solved by the invention.
Disclosure of Invention
The invention provides a folding trailer, which realizes the folding design of the trailer so as to improve the portability of the trailer and further improve the user experience.
The invention provides a folding trailer which comprises a first frame body, a second frame body and two third frame bodies; rotating seats are arranged on two sides of the first frame body, one end part of the third frame body is rotatably arranged on the rotating seat on the corresponding side, wheels are arranged on the other end part of the third frame body, a first connecting shaft is further arranged on the second frame body, one end part of the second frame body is rotatably arranged on the first frame body, and second connecting shafts are respectively arranged on two sides of the second frame body; a connecting rod is arranged between the first connecting shaft and the second connecting shaft on the corresponding side; the first support body is provided with a cross beam, the middle of the cross beam is fixedly connected to the first support body, and the length direction of the cross beam is perpendicular to that of the first support body.
Further, the rotating seat is arranged obliquely downwards.
Further, the second connecting shaft is arranged obliquely relative to the third frame body.
Furthermore, the third support body includes two bracing pieces and wheel seat, two the bracing piece is parallel to each other and articulates wheel seat and corresponding side rotate between the seat, rotate seat, two form four-bar linkage between bracing piece and the wheel seat, the wheel sets up on the wheel seat.
Furthermore, the first frame body is provided with an installation seat, the second frame body is rotatably arranged on the installation seat, the installation seat is provided with a first bolt hole, and the second frame body is provided with a second bolt hole; a latch is inserted in the first latch hole and the second latch hole when the folding trailer is in an unfolded state.
Further, first support body includes first mobile jib and first telescopic link, first mobile jib is hollow structure, first telescopic link is inserted in first mobile jib and can for first mobile jib telescopic sliding.
Furthermore, the second support body comprises a second main rod and a second telescopic rod, the second main rod is of a hollow structure, and the second telescopic rod is inserted into the second main rod and can slide in a telescopic mode relative to the second main rod.
Furthermore, the first frame body and/or the second frame body are/is provided with a detachable bearing seat.
According to the folding trailer provided by the invention, by adopting the second frame body and the third frame body which are designed to be folded, when the folding trailer is used, the second frame body is stretched and drives the third frame body to be opened at the same time, so that wheels at two sides are separated to support, and the first frame body can be loaded with articles to be transported according to the requirement; and under the user state not, the second support body rotates foldingly to make the third support body of both sides and lean on the both sides at first support body, the whole volume of trailer under fold condition is less, is convenient for place the transportation on the car, and then the portability of effectual promotion trailer, in order to improve user experience nature.
