Two-level side door opening and closing mechanism of van vehicle

Abstract

A two-level side door opening and closing mechanism of a van vehicle comprises a first-level door and a second-level door arranged at the compartment opening position. The top of the first-level dooris located on the top of the opening position of a compartment; the bottom of the first-level door is hinged to the top of the second-level door; the bottom of the second-level door is hinged to the bottom of the compartment; a locking device is further arranged on the top of the second-level door; the side wall of the compartment is provided with a locking groove matched with the locking device;automatic door popping-open mechanisms, a control unit and a wire winding mechanism arranged on the side wall of the compartment are further included; the automatic door popping-opening mechanisms arearranged between the upper portion of the side, facing the compartment, of the first-level door and the compartment; the control unit is connected with the automatic door popping-opening mechanisms,the wire winding mechanism and the locking device; and the wire winding mechanism is connected with the top of the first-level door. Compared with the prior art, according to the two-level side door opening and closing mechanism of the van vehicle, efficiency is effectively improved, the labor force is saved, a safety coefficient is increased, and automatic control and precision control can be conveniently achieved.

Description

technical field [0001] The invention relates to a door structure of a van, in particular to a secondary side door opening and closing mechanism of a van. Background technique [0002] During the transportation of vans, in order to facilitate the loading and unloading of goods, the side doors of vans are often set in the form of side-by-side doors or rolling doors. During the transportation process, it is easy to be bumped and dropped from the compartment; when the rolling door structure is adopted, when the rolling door is opened, the goods in the compartment will be exposed as a whole, and when the goods are moved, the goods under the compartment are also easy to be knocked to the ground; The existing side-by-side doors or rolling doors are mostly set to open and close by hydraulic control or human control. However, the efficiency of manpower control is not high, and when the door is heavy, it takes a lot of force to open the door, and the hydraulic control brake There wil...

[0002] During the transportation of vans, in order to facilitate the loading and unloading of goods, the side doors of vans are often set in the form of side-by-side doors or rolling doors. During the transportation process, it is easy to be bumped and dropped from the compartment; when the rolling door structure is adopted, when the rolling door is opened, the goods in the compartment will be exposed as a whole, and when the goods are moved, the goods under the compartment are also easy to be knocked to the ground; Most of the existing side-by-side doors or rolling doors are set to open and close by hydraulic control or manual control. However, the efficiency of the opening and closing of the manual control door is not high, and when the door is heavy, it takes a lot of force to open the door, while the hydraulic control brake There will be a lot of energy loss during the working process, and there will be a certain amount of liquid leakage in the hydraulic transmission, which will easily lead to insufficient power when the door is opened and closed, and it is difficult to diagnose the fault of the hydraulic system
