Abstract: A foldable ladder is provided for an automobile cargo bed and includes a mounting base mounted to a sideboard of the cargo bed. The mounting base has a bottom part that is pivotally coupled, by means of a first pivot joint unit, to a pivot axle, which is pivotally coupled to a pivot joint end of a frame to form a second pivot joint unit. Two side portions of the frame are respectively coupled to extension/retraction bars that are extendable outward from an operation end. Ends of the extension/retraction bars are pivotally coupled through a third pivot joint unit to ladder assembly that includes rungs. The foldable ladder positionable between the cargo bed and the ground in an expanded condition and is positioned against the sideboard of the cargo bed so as not to occupy the space of the cargo bed.

Abstract: A top cover support structure is connected between an open-top rear cargo bed of a truck and a top cover to serve as a support structure for opening and closing the cover. The transmission linkage includes a fixed bar mounted to the open-top rear cargo bed, a movable bar mounted to the top cover, and first and the second swing bars each having ends pivotally connected to the fixed bar and the movable bar. A bottom bracket is mounted to a side panel of the open-top rear cargo bed to receive the fixed bar of the transmission linkage to attach thereto. A top cover retention seat is mounted to the top cover to receive the movable bar to attach thereto. A hydraulic (pneumatic) cylinder is pivotally connected to the open-top rear cargo bed and the top cover.

Abstract: A complex wheel rim assembly structure contains a hub, a front member, a rear member, a leak-proof O-ring, and plural assembly members. The hub includes plural radial plates and assembly holes. An inward folding edge is close to a central hole of the front member and has plural assembly holes, and an outward expanding edge is at an exterior side of the front member. An inward folding edge is close to a central hole of the rear member and has plural assembly holes, and an outward expanding edge is at an exterior side of the rear member. Grooves are at exterior sides of the inward folding edges of the front and rear members, the leak-proof O-ring is between the two inward folding edges of the front and rear members, and the wheel rim is assembled through the plural assembly members.

Abstract: A vehicle trunk lid is provided with a lid which can cover on the vehicle trunk. Hinges are provided below the trunk lid for connecting to the side boards of the trunk, while respective hydraulic bars are provided below the two sides of the trunk, including side bars and several horizontal bars, such that the trunk may have a private space for storage purposes, and can be locked up. The support frame can bear and hold large freight.

Abstract: A support structure for an upper cover of an automobile rear loading platform, which is installed on two sides between a rear end portion of an automobile rear loading platform and an upper cover of the rear loading platform, wherein a base mount is fixed to a bottom plate of the rear loading platform, and a supporting arm is pin connected to the base mount. Another end of the supporting arm is pin connected to a suspension arm, and another end of the suspension arm is pin connected to a fixing mount that enables fixing to a bottom portion of the upper cover. An oil pressure rod is pin configured between the aforementioned supporting arm and the base mount, thereby providing support therebetween. Accordingly, good support and buffering effectiveness is achieved when opening and closing the upper cover.
