Embodiment 1

[0032] Specifically referring to Figures 1-4 , this embodiment discloses a rolling shutter blade, including two groups of blades 1, and at least one end of each group of blades 1 is provided with a fitting part 11;

[0033] A connecting member 2, which has two groups of centrally symmetric bending parts 21 formed inside. Each of the bending parts 21 is rotationally fitted with a fitting part 11. During the rotation of the blade 1 on the connecting member 2, the unfolding and folding of the blade 1 are realized.

[0034] The two groups of blades 1 provided by the present utility model are rotationally connected through the connecting member 2 to form an opening and closing action of 0-180°, realizing the unfolding and folding of the rolling shutter blade, with convenient operation. When multiple rolling shutter blades are applied to a pickup truck rolling shutter, it can not only ensure that the rolling shutter has sufficient strength to withstand various external forces, but also meet the lightweight design of the rolling shutter blade.

[0035] Among them, the blade 1 is made of aluminum alloy material, and a layer of high-strength plastic shell is covered on the surface of the blade 1, and the plastic shell can play a role in protecting the aluminum alloy blade.

[0036] In a preferred embodiment, the fitting part 11 includes a shaft fitting part 111, a first fitting part 112 arranged outside the shaft fitting part 111, and a second fitting part 113 arranged inside the shaft fitting part 111.

[0037] In a preferred embodiment, the bending portion 21 includes a rotating shaft 211 and a rotating shaft fitting cavity 212 (a cavity formed by the rotating shaft 211 and the connecting member 2). The rotating shaft fitting cavity 212 and the rotating shaft fitting portion 111 are rotationally fitted with the rotating shaft 211 as the center, and the abutting portion 11 realizes the unfolding and folding of the rolling curtain blade 1 during the rotation of the bending portion 21.

[0038] In a preferred embodiment, the connecting member 2 further includes a first abutting and fitting portion 22 and a second abutting and fitting portion 23 respectively arranged at both ends of the bending portion 21. The first abutting and fitting portion 22 and the second abutting and fitting portion 23 are respectively engaged with the first abutting portion 112 and the second abutting portion 113 during the rotation process.

[0039] In a preferred embodiment, during the unfolding process of the blade 1, an abutting cavity 3 is formed during the combination process of the second abutting and fitting portion 23 and the second abutting portion 113.

[0040] In a preferred embodiment, during the unfolding process of the blade 1, a fitting surface 4 is formed during the combination process of the first abutting and fitting portion 22 and the first abutting portion 112.

[0041] In a preferred embodiment, in the folded state of the blade 1, the rotating shaft 211, the second abutting and fitting portion 23 and the second abutting portion 113 form a first cavity 5.

[0042] In a preferred embodiment, in the folded state of the blade 1, the rotating shaft 211, the first abutting and fitting portion 22 and the second abutting portion 113 form a second cavity 6.

[0043] In a preferred embodiment, a plurality of through holes 24 are provided on the connecting member 2. The installation positions of the through holes 24 are not specifically limited. In this embodiment, the through holes 24 are provided on the rotating shaft 211. The through holes 24 can also be provided at the center of the connecting member 2. The provision of the through holes 24 on the connecting member 2 enables the rolling curtain blade to have a good air permeability function and at the same time realizes the lightweight design of the rolling curtain blade.

[0044] Since pickup trucks are often used in harsh environments, such as humid, rainy, salty areas or often in contact with dust, mud, etc., if traditional sealed rolling curtains are used for pickup trucks, they are relatively heavy. If traditional folding rolling curtains are used, it is easy to accumulate water or dust, affecting the normal use of pickup truck rolling curtains.

[0045] When the rolling curtain blade provided in this embodiment is folded, a small amount of rainwater flows down the vertical blade 1 into the cavity formed by the second abutting and fitting portion 23 of the connecting member 2 and the abutting cavity 3, preventing rainwater, dust, etc. from hindering the rolling curtain from being stored; when the rolling curtain blade is opened, during the rotation process of the rotating shaft fitting cavity 212 and the rotating shaft fitting portion 111 with the rotating shaft 211 as the center, the second abutting and fitting portion 23 pushes out rainwater, dust, etc. from the abutting cavity 3. Embodiment 2

[0046] Specifically refer to Figures 4-8 , this embodiment discloses a rolling shutter door, which includes a plurality of rolling shutter blades described in Embodiment 1, and the plurality of rolling shutter blades are driven by a pull rope or a motor. Embodiment 3

[0047] This embodiment discloses a high cover for a pickup truck. The rolling shutter door described in Embodiment 2 is installed on the high cover of the pickup truck. The rolling shutter blade 1 is installed on the pickup truck, and an adjustable sealing strip is provided at the edge of the blade 1. The sealing strip can be adjusted according to the shape and size of the carriage to ensure the sealing performance.

[0048] The above embodiments only represent certain implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model; therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
