Description

Technical Field

[0001] This utility model relates to the technical field of wing door devices, specifically an automatic hydraulic double wing door device for a rear equipment compartment. Background Technology

[0002] The wing door is a unique vehicle door design characterized by its upward-opening shape, resembling a wing, hence it is also known as the "eagle wing door," "wing door," or "gull wing door." The wing equipment compartment is an improvement on the ordinary equipment compartment. It is a special equipment compartment that can be opened by manual or hydraulic means, featuring fast loading and unloading speed, high efficiency, and the ability to load and unload from the side. Traditionally, wing equipment compartments require manual entry after opening the door to retrieve items, resulting in low retrieval efficiency. To improve this situation, an automatic hydraulic double wing door device for the rear equipment compartment has been proposed.

[0003] As disclosed in the authorization announcement number CN213676921U, a wing car body includes a car body main body and further includes: a T-shaped main beam, which is fixedly installed on the car body main body along the extension direction of the car body main body; wing doors, which are arranged on both sides of the T-shaped main beam; a drive block, which is installed at the end of the car body main body and is hinged to the wing door; and a control module, which is used to control the drive block and is electrically connected to the drive block.

[0004] Although it allows for the initial movement of the entire wing door outwards a certain distance before moving it upwards a certain distance, ensuring the lower wing is as high as possible above a person, the angle between the lower and upper wing can then be controlled and adjusted. This reduces the radius required for the wing door to deploy, minimizes the overlap between the space occupied by the wing door during deployment and the space occupied by the human body, and greatly ensures the personal safety of people near the wing vehicle;

[0005] However, it does not solve the problem that the existing wing door device is not conducive to convenient linkage opening and closing of the wing door and parallel pushing of the shelf out of the warehouse, which is not conducive to the temporary placement of miscellaneous items and the retrieval or placement of goods on the shelf, thus affecting the convenience of use.
