Disclosed are embodiments of a retractable tonneau cover for a vehicle that has been modified in order to generally minimize the size of a housing of the tonneau cover, providing more vehicle cargo space for a user. The modified retractable tonneau cover can be automatically closed through an electronic system.

A retractable truck bed closure is disclosed herein. The retractable truck bed closure comprises a pair of frames that extend across a truck bed between sidewalls of the truck bed. The closure may be moved between a stored configuration and an extended configuration along the pair of frames to open, and close, a portion of the truck bed, respectively. The frames may be attachable to the truck, or may be integrated into portions of the truck, such as the sidewalls of the truck bed or the rear of the cab of the truck.

A refuse vehicle includes a chassis, a body assembly coupled to the chassis, an electric energy system, and a door system. The body assembly defines a refuse compartment. The body assembly has a cover that at least partially encloses the refuse compartment such that an opening is defined in the body assembly to provide access to the refuse compartment. The door system is coupled to the cover. The door system includes a panel and an electric actuator powered by the electric energy system. The electric actuator is configured to selectively reposition the panel between a first position where the panel extends across the opening and a second position where the panel does not extend across the opening.

The retractable tonneau cover for truck bed vehicles and similar, object of the present invention, comprises a mechanism box (100) provided with a winding stress shaft (10), and in the electric model, a drive axle (20) driven by an electric motor that enable the movement of opening and closing a retractable tonneau cover mat. The mechanism box is provided with an embodiment that improves the drainage system in order to prevent the accumulation of water inside it. In addition to the electrical model, the box (100) has a relief on its face that receives the control module with access from the outer portion, which improves accessibility and avoids the need to open the entire set, in case it needs maintenance, further having a management and activation system via Bluetooth and radio frequency.

A drive system for operation of a roll top cover for covering a cargo bed of a vehicle enables improved and smoother roll top cover movement. The drive system includes: an elongate housing that defines a longitudinal axis and first and second ends, the housing including an axially extending aperture for receiving the roll top cover therethrough; first and second receiving plates disposed transversely within the housing at the respective first and second ends thereof, the receiving plates comprising opposed spiral-shaped slots extending therethrough, each of the spiral-shaped slots having an open end proximally and a closed end distally; and a drive shaft assembly disposed within the housing and extending axially between the first and second ends thereof; wherein the drive shaft assembly is adapted for being operably connected to a drive chain and driving movement thereof within the spiral-shaped slots during operation of the roll top cover.

The present invention discloses a box cover device extended and retracted in a transmission manner and a control method thereof. The device comprises a transmission gear, a roller shutter shaft gear and a clutch gear. The transmission gear and the roller shutter shaft gear are arranged oppositely, and a clutching space is reserved between the transmission gear and the roller shutter shaft gear. A middle shaft is arranged at the center line of the clutching space vertical to the center connection line of the transmission gear and the roller shutter shaft gear. The box cover device extended and retracted in a clutch type transmission manner of the present invention is convenient and quick to operate and has high working efficiency

A side rail for a cargo bed of a vehicle comprising an elongate body that defines a longitudinal axis; an axially extending drive channel disposed at a medial side of the body and defining an opening therein for receiving a drive chain, the drive channel having a recessed inner portion and a stepped outer portion adjacent the opening; a first receiving channel disposed within an upper wall of the outer portion of the drive channel and extending axially therealong; a first sealing member disposed within the first receiving channel; a second receiving channel disposed opposite the first receiving channel within a lower wall of the outer portion of the drive channel and extending axially therealong; and a guide element disposed within the second receiving channel and projecting upwardly therefrom, the guide element having an upper contact surface for slidably contacting a surface of the drive chain.

A lid arrangement for a canister for a rollup truck bed cover comprises a lid and a canister. The canister has a main housing part and opposite housing end parts. The lid spans between said housing end parts across the main housing part, and the lid is pivotally connected to at least one of the housing end parts. The pivotal lid need not be taken fully off the canister when access is needed to the main housing part, e.g. to inspect the drain(s) or wipe up water inside the canister.

A rear corner element for a truck bed cover serve to guide rainwater exterior to the truck bed wall. The rear corner element has a mounting part and a cover part. The mounting part has a base mounting part adapted for being secured on top of the rear end of a side wall of the truck bed in elongated of a coupling rail adapted for mounting a roll-up truck bed cover to said side wall of the truck bed, a first front end part configured to be assembled to a free rear end of the coupling rail in lengthwise extension of said coupling rail, a first rear end part opposite the first front end part, and at least one rainwater diverting channel and/or chamber extending lengthwise of the mounting part from the rainwater inlet to the first rear end part.
