[0001] The utility model belongs to the technical field of rolling covers, and particularly relates to a rolling cover lock structure and a motor vehicle rolling cover.

Background Art

[0002] In recent years, with the development of motor vehicles, pickups with an open-box carriage have become increasingly popular. A pickup is a light-duty truck with an open cargo box behind the cab and the cargo box side panels integrated with the cab. It is a passenger-cargo dual-purpose vehicle that looks like a sedan in the front and has a cargo box in the back.

[0003] For more convenient use, a motor vehicle rolling cover is usually installed on the carriage, and a rolling cover lock structure is provided to protect the carried goods from being affected by the weather environment and theft, facilitate the user to open and close the box cover, and make the appearance of the pickup truck more beautiful.

[0004] The existing motor vehicle rolling cover lock structure is as Figure 5 shown. It drives the first pull rod 202 and the second pull rod 203 to rotate by a toggling member 201, and then pulls the first wire 204 and the second wire 205, so that the first locking tongue 206 and the second locking tongue 207 connected to the first wire 204 and the second wire 205 slide synchronously to lock or unlock. However, due to the structural layout of this motor vehicle rolling cover lock structure, the first pull rod 202 and the second pull rod 203 are arranged on one side of the lock mounting plate 208, and their structures are different. When the toggling member 201 drives the first pull rod 202 and the second pull rod 203 to rotate, the rotation strokes of the first pull rod 202 and the second pull rod 203 are different, and the lengths of the first wire 204 and the second wire 205 are different, resulting in inconvenient production and reduced production efficiency.
