Description
TECHNICAL FIELD

The present disclosure belongs to the technical field of camping wagon manufacture, and in particular relates to a camping wagon.


BACKGROUND

With the improvement of people's living standards, most travel enthusiasts prefer to stay overnight and rest in tourist destinations by camping. People will bring a lot of items when they go to the beach or camping, such as surfboards, umbrellas, tents, benches, dining tables, food, drinks and other leisure equipment. Therefore, camping wagons with both camping and cargo carrying functions are becoming increasingly popular among travel enthusiasts.


At present, the frame of the camping wagon on the market basically includes a folding bottom frame as the chassis, with vertical rods at four corners of the folding bottom frame and foldable cross frames between the vertical rods. The two ends of the cross frame are basically hinged to the top and bottom ends of the vertical rod, respectively. When the camping wagon is idle, it is folded to avoid occupying space. However, when the camping wagon is folded, the height of the cross frame is greater than the height of the support rod, resulting in a large overall height of the camping wagon. This type of camping wagon cannot minimize its volume to the greatest extent possible (at present, related products in this field can only achieve a capacity of 90-100 L, resulting in problems of large volume, small capacity, and poor practicality). Therefore, it is highly desirable to develop a camping wagon that can reduce the overall folded height of the camping wagon, minimize the space occupied by the camping wagon to the greatest extent possible, and facilitate outdoor carrying.


SUMMARY

Design Objective: To overcome the shortcomings of the prior art mentioned in the background section, the present disclosure designs a camping wagon. The present disclosure reduces the folded height of the camping wagon, achieving high portability and large capacity (The folded volume of the camping wagon is limited to 45 cm*35 cm*20 cm, and the unfolded capacity thereof reaches 150 L). Meanwhile, the camping wagon features lower sales costs and more cost-effective packaging in the e-commerce field.


Design Solution: The present disclosure aims to achieve the above design objective.


1. Upper side ends of two second X-shaped movable frames of a second folding side frame are respectively hinged to corresponding support rods through linkage rods; and upper ends of two sides of a third X-shaped movable frame of a first folding side frame are respectively hinged to corresponding support rods through linkage rods. This is a first technical feature of the present disclosure. The objective of the design is as follows. Upper side ends of two second X-shaped movable frames of a second folding side frame are respectively hinged to corresponding support rods through linkage rods; and upper ends of two sides of a third X-shaped movable frame of a first folding side frame are respectively hinged to corresponding support rods through linkage rods. Due to the linkage rods, the vertical heights of the second folding side frame and the first folding side frame will not be greater than the height of the support rod after folding. The design reduces the overall folded height of the camping wagon, minimizes the space occupied by the camping wagon to the greatest extent possible, and facilitates outdoor carrying.


2. The second folding side frame includes two first cross rods, four second cross rods, and two linkage rods; middle portions of two second cross rods are hinged to form one first X-shaped movable frame, and remaining two second cross rods are respectively hinged to corresponding first cross rods to form the two second X-shaped movable frames; an upper end of the first cross rod of one second X-shaped movable frame is hinged to an upper end of a corresponding second cross rod of the first X-shaped movable frame, and a lower end of the second cross rod of the second X-shaped movable frame is hinged to a lower end of a corresponding second cross rod of the first X-shaped movable frame; a lower end of the first cross rod is hinged to a lower part of the corresponding support rod through a hinge element; one side end of one linkage rod is hinged to an upper part of the corresponding support rod through a hinge element, and the other side end of the linkage rod is hinged to an upper end of the second cross rod of the second X-shaped movable frame; an upper end of the first cross rod of the other second X-shaped movable frame is hinged to the upper end of the corresponding second cross rod of the first X-shaped movable frame, and the lower end of the second cross rod of the second X-shaped movable frame is hinged to the lower end of the corresponding second cross rod of the first X-shaped movable frame; a lower end of the first cross rod is hinged to a lower part of the corresponding support rod through a hinge element; one side end of the other linkage rod is hinged to an upper part of the corresponding support rod through a hinge element, and the other side end of the linkage rod is hinged to the upper end of the second cross rod of the second X-shaped movable frame; and a length of the first cross rod is greater than a length of the second cross rod. This is a second technical feature of the present disclosure. The objective of the design is as follows. The second folding side frame includes two first cross rods, four second cross rods, and two linkage rods; middle portions of two second cross rods are hinged to form one first X-shaped movable frame, and remaining two second cross rods are respectively hinged to corresponding first cross rods to form the two second X-shaped movable frames; an upper end of the first cross rod of one second X-shaped movable frame is hinged to an upper end of a corresponding second cross rod of the first X-shaped movable frame, and a lower end of the second cross rod of the second X-shaped movable frame is hinged to the lower end of the corresponding second cross rod of the first X-shaped movable frame; the lower end of the first cross rod is hinged to a lower part of the corresponding support rod through a hinge element; one side end of one linkage rod is hinged to an upper part of the corresponding support rod through a hinge element, and the other side end of the linkage rod is hinged to the upper end of the second cross rod of the second X-shaped movable frame; an upper end of the first cross rod of the other second X-shaped movable frame is hinged to the upper end of the corresponding second cross rod of the first X-shaped movable frame, and the lower end of the second cross rod of the second X-shaped movable frame is hinged to the lower end of the corresponding second cross rod of the first X-shaped movable frame; a lower end of the first cross rod is hinged to a lower part of the corresponding support rod through a hinge element; one side end of the other linkage rod is hinged to an upper part of the corresponding support rod through a hinge element, and the other side end of the linkage rod is hinged to the upper end of the second cross rod of the second X-shaped movable frame; and a length of the first cross rod is greater than a length of the second cross rod. When the second folding side frame is in a folded state, an upper end surface of the first cross rod is flush with an upper end surface of the support rod, or the upper end surface of the first cross rod is lower than the upper end surface of the support rod. A distance between a hinge point of the second X-shaped movable frame and the upper end of the first cross rod of the second X-shaped movable frame matches a distance between the hinge point of the second X-shaped movable frame and the upper end of the second cross rod of the second X-shaped movable frame. The design structure of one first X-shaped movable frame and two second X-shaped movable frames reduces the overall folded height of the camping wagon while ensuring that the length of the camping wagon remains unchanged. That is, the present disclosure reduces the folded height, ensures a certain folding volume (45 cm*35 cm*20 cm), and achieves a breakthrough capacity (150 L). The camping wagon has the advantages of being more portable, having a larger capacity, lower sales costs in the e-commerce field, and more cost-effective packaging, greatly reducing transportation costs for products of the same capacity. The present disclosure further reduces the space occupied by the camping wagon, making it easier for users to carry it when going out.

When one end of the first cross rod 6 is located in the mounting groove 15 of the corresponding second hinge portion 92 and the pin shaft through hole is aligned with the first cross rod through hole, the first cross rod 6 is hinged to the corresponding second hinge portion 92 through a pin shaft.


When the second folding side frame 4 is in an unfolded state, a lower surface of the first cross rod 6 of the second folding side frame 4 is abutted against a bottom of the corresponding mounting groove 15, and a lower surface of the linkage rod 8 of the second folding side frame 4 is abutted against a bottom of the corresponding mounting groove 15. When the first folding side frame 3 is in an unfolded state, a lower surface of the first cross rod 6 of the first folding side frame 3 is abutted against a bottom of the corresponding mounting groove 15, and a lower surface of the linkage rod 8 of the first folding side frame 3 is abutted against a bottom of the corresponding mounting groove 15. The lower surface of the first cross rod 6 is abutted against a bottom of the corresponding mounting groove 15, that is, the mounting groove 15 is abutted against the first cross rod 6 in a limited manner. The lower surface of the linkage rod 8 is abutted against a bottom of the corresponding mounting groove 15, that is, the mounting groove 15 is abutted against the linkage rod 8 in a limited manner. In this way, the design improves the hinge stability at the hinge point when the second folding side frame 4 or the first folding side frame 3 is in an unfolded state, thereby enhancing the usability of the camping wagon.


A bottom of each of the four support rods 5 is provided with wheel assembly 10. The wheel assembly 10 is a prior art and will not be further described here. The wheel assembly 10 makes it convenient for the user to transport items by the camping wagon.


The folding frame 1 is provided with a handle assembly. The handle assembly includes mounting rod 11 and a handle rod 12. The mounting rod 11 is provided between the two support rods 5 in the width direction of the folding bottom frame 2, and the handle rod 12 is provided at a middle portion of the mounting rod 11. Each of two ends of the mounting rod 11 is provided with one rotating element 13. Each of the two support rods 5 is provided with one connecting element 14. A rotating space is formed inside the connecting element 14, and the rotating element 13 is rotatably provided in the corresponding rotating space. In this way, the user can control the tilt of the handle rod 12 at a certain angle, making it convenient for the user to move the camping wagon by pulling the handle rod 12. Therefore, it is effort-saving for the user to move items by the camping wagon.


The mounting rod 11 includes left mounting rod 111, right mounting rod 112, and connecting portion 113 provided between the left mounting rod 111 and the right mounting rod 112. One end of the left mounting rod 111 and one end of the right mounting rod 112 are respectively hinged to corresponding rotating elements 13. Two sides of an upper end surface of the connecting portion 113 are respectively provided with connecting grooves, and the connecting grooves extend outward and penetrate outer end surfaces of corresponding ends. The other end of the left mounting rod 111 and the other end of the right mounting rod 112 are respectively hinged in the corresponding connecting grooves. A bottom end of the handle rod 12 is fixedly provided on an upper part of the connecting portion 113.


When the handle assembly is in an unfolded state, a lower surface of the left mounting rod 111 is abutted against a bottom of the corresponding connecting groove, and a lower surface of the right mounting rod 112 is abutted against a bottom of the corresponding connecting groove.


Before folding the camping wagon, the user can press down the handle rod 12 to tilt the left mounting rod 111 and the right mounting rod 112 to a certain extent. The two support rods 5 used for mounting the mounting rods approach each other, such that the left mounting rod 111 and the right mounting rod 112 approach each other, thereby completing the folding. The design reduces the overall folded volume of the camping wagon.
