Description

Technical Field

[0001] The present application relates to the field of wing-span carriages, and in particular to an electrically powered wing-opening carriage. Background Art

[0002] The wing-opening compartment, also known as the wing-span compartment or the flying wing compartment, is a special van. It can open the wing panels on both sides of the compartment through manual or hydraulic devices. The loading and unloading equipment can load and unload the goods directly from both sides, making loading and unloading of goods more convenient and efficient.

[0003] Winged vehicles can be mainly used for the transportation and distribution of auto parts, paper, home appliances, clothing, chemicals, beverages, food and other items. Ordinary vans can only be loaded and unloaded from the tailgate of the cargo compartment, which takes a long time. The advantage of winged vehicles is that the two side panels can be opened, and they can be loaded and unloaded from the side, which greatly shortens the loading and unloading time of goods and improves logistics efficiency. Some of the winged vehicles on the market are opened manually, which is time-consuming and laborious; some are opened by oil cylinders, which are prone to problems such as jamming and oil leakage, and are not very reliable.

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] An electric wing opening carriage comprises: an upper side plate 1, a lower side plate 2, a first sprocket 3, a second sprocket 4, a third sprocket 5, a fourth sprocket 6, a fifth sprocket 7, a first chain 8 and a second chain 9. The first sprocket 3, the second sprocket 4, the third sprocket 5 and the fourth sprocket 6 are all rotatably connected to the upper part of the front wall of the carriage, the first sprocket 3 and the third sprocket 5 are located on one side of the front wall of the carriage, the second sprocket 4 and the fourth sprocket 6 are located on the other side of the front wall of the carriage, and the fifth sprocket 7 is rotatably connected to the lower part of the front wall of the carriage. An upper pull rod 10 and a lower pull rod 11 are fixed to the upper side plate 1, the upper pull rod 10 is hinged to the first sprocket 3, the lower pull rod 11 is hinged to the front wall of the carriage, and the lower side plate 2 is hinged to the bottom plate of the carriage. The first chain 8 is wound around the first sprocket 3 and the second sprocket 4 , one end of the second chain 9 is hinged to the first chain 8 , the other end of the second chain 9 is hinged to the lower side plate 2 , and the second chain 9 is wound around the third sprocket 5 , the fourth sprocket 6 and the fifth sprocket 7 .

[0021] In this embodiment, a motor is used to drive the second sprocket 4 to rotate. When the carriage needs to be opened, the motor is started, and the motor drives the second sprocket 4 to rotate counterclockwise, thereby driving the first chain 8 to rotate. At this time, during the rotation of the first chain 8, the upper pull rod 10 is driven by the force of the first chain 8 to drive the upper side plate 1 to rotate, thereby opening the upper side plate 1; in the initial state, the lower side plate 2 is closed by the pulling force of the second chain 9, and during the rotation of the first chain 8, the pulling force of the second chain 9 disappears, and the lower side plate 2 rotates and opens under the action of gravity. At this time, during the opening process of the lower side plate 2, the gravity of the lower side plate 2 assists the rotation of the first chain 8, thereby achieving the effect of energy saving during the opening process of the carriage.

[0022] In one embodiment, an upper side panel 1 and a lower side panel 2 are provided on both sides of the carriage, and corresponding sprockets and chains are provided on the front and rear walls of the carriage, so that both sides of the carriage can be opened, and the forces on the upper side panel 1 and the lower side panel 2 are balanced through the corresponding sprockets and chains on the front and rear walls of the carriage.

[0023] Through the above method, the motor is used to provide power, and the opening and closing can be remotely controlled, which saves time and effort; the chain and mechanical mechanism are used to open and close the carriage to ensure the smooth transmission of the motor power, and the chain is durable and highly reliable.

[0024] In one embodiment, the first chain 8 is provided with two limiters 12, and the two limiters 12 are located on both sides of the upper pull rod 10. The limiter 12 can be a photoelectric switch, and the photoelectric switch senses the position of the upper pull rod 10 to control the start and stop of the motor. When the photoelectric switch close to the first sprocket 3 detects the upper pull rod 10, the upper side door is in the maximum open position, and when the photoelectric switch close to the second sprocket 4 detects the upper pull rod 10, the upper side door is in the closed position.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
