[0015] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, a cargo box hidden wind hook structure can be used on the cargo box of a pure electric light truck, and is used to keep the cargo box door 1 open after it is opened, so as to facilitate smooth loading and unloading of goods, and at the same time prevent the cargo box door 1 from automatically closing and causing impact under the action of external forces such as wind, thereby helping to protect the cargo box door 1. In this embodiment, a hidden groove 2 is provided at the bottom of the cargo box door 1, and the hidden groove 2 is arranged at the outer end opening of the cargo box door 1, that is, the bottom end and the side end of the hidden groove 2 are connected to the outside of the cargo box door 1, so as to prevent the state change of the wind hook structure from being hindered during use, so that it can be used smoothly.

[0017] This embodiment includes a fixing ring 4 installed in the hidden groove 2, and a first wind hook arm 5 is movably connected to the fixing ring 4, and an end of the first wind hook arm 5 away from the fixing ring 4 is movably connected to a second wind hook arm 6, and an end of the second wind hook arm 6 away from the first wind hook arm 5 is movably connected to a hook ring 7, and a fixing shaft 8 is fixedly installed at the bottom of the cargo box side panel 3, and the hook ring 7 and the fixing shaft 8 can be detachably fitted together.

[0018] When the cargo box door 1 is in a closed state, the fixing ring 4, the first wind hook arm 5, the second wind hook arm 6 and the hook ring 7 are all in the hidden groove 2, and the hidden groove 2 can be closed with the help of the bottom plate of the cargo box, so as to hide the above structure. Therefore, when the cargo box door 1 is in a closed state, the fixing ring 4, the first wind hook arm 5, the second wind hook arm 6 and the hook ring 7 are in an externally invisible state, avoiding long-term exposure of the main body of the wind hook structure, helping to prevent corrosion or wear thereof, thereby protecting it and extending its service life; when in use, the cargo box door 1 is opened, and during the opening process of the cargo box door 1, the first wind hook arm 5, the second wind hook arm 6 and the hook ring 7 lose the support of the bottom wall of the cargo box, and freely fall along the fixing ring 4 to a vertical state, until the cargo box door 1 is opened to the maximum state, and the hook ring 7 is mounted on the fixed shaft 8. Under the pull of the first wind hook arm 5 and the second wind hook arm 6, the hook ring 7 and the fixed shaft 8 have sufficient friction, so that the two will always maintain the set state, thereby achieving the maintenance of the open state of the cargo box door 1. If there is concern that its retention performance is not enough, a detachable pin can be set through the fixed shaft 8 to limit the set of the hook ring 7 to prevent the two from detaching. Specifically, the pin can be set on the vehicle body or the fixed shaft 8 through a ring chain to facilitate use and avoid loss.

[0019] Since the fixed shaft 8 and the hidden groove 2 are not at the same height and the fixed shaft 8 is set at a lower height, in this embodiment, the length of the first wind hook arm 5 is greater than the length of the second wind hook arm 6, so that the second wind hook arm 6 can change direction flexibly and the adaptation space required for changing direction is small, so that the hook ring 7 can be successfully mounted on the fixed shaft 8.

[0020] In this embodiment, assembly rings 9 are respectively provided at both ends of the first wind hook arm 5, one of the assembly rings 9 is movably arranged through the fixed ring 4, and the other assembly ring 9 is movably arranged through the second wind hook arm 6. The assembly ring 9 can flexibly change its position on the fixed ring 4 to adapt to the opening and closing of the cargo box door 1.

[0021] The two ends of the second wind hook arm 6 are respectively provided with connecting rings, one of which is movably arranged through the assembly ring 9, and the other is movably arranged through the hook ring 7. The connecting ring can flexibly change its position on the assembly ring 9 and the hook ring 7, so that the second wind hook arm 6 can flexibly adapt to the angle change that must be generated due to the setting position of the fixed shaft 8.

[0022] The description of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
