Abstract
The utility model discloses a kind of Environmental-friendelectric electric vehicle rear-door opening device, comprise casing (1), hinge (2), back door (4), back door (4) is hinged on the lateral wall of casing (1) described in the top of casing (1) by hinge (2) and is fixed with lower stator (6), back door (4) is fixed with stator (3), air spring (5) is hinged with between upper stator (3) and lower stator (6), the upper link point (7) of upper stator (3) and air spring (5) is positioned at before the lower link point (8) of lower stator (6) and air spring (5) and the pin joint of back door (4) and casing (1) when back door (4) are closed, the upper link point (7) of upper stator (3) and air spring (5) is positioned at when back door (4) open after the lower link point (8) of lower stator (6) and air spring (5) and the pin joint of back door (4) and casing (1).After adopting this said structure, have simple and reasonable, operation uses light, good seal performance, do not produce secondary pollution, transport is by features such as time restrictions.
Description
Technical field
The utility model relates to a kind of Environmental-friendelectric electric vehicle, particularly a kind of quick closedown of Environmental-friendelectric electric vehicle case rear door or the Environmental-friendelectric electric vehicle rear-door opening device opened.
Background technology
Along with development, the growth in the living standard of society, the household garbage of resident gets more and more, and the phenomenon that household garbage disturbs residents is more and more general, and living environment worse and worse.For this reason, advocate energy-conserving and environment-protective, advocate green energy resource and become the common slogan of people gradually and actively implemented.In this context, all kinds of Environmental-friendelectric electric vehicle is developed rapidly, constantly improves the living environment of people.But current Environmental-friendelectric electric vehicle has the following disadvantages this part: one is that back door structure is unreasonable, open the door or to waste time and energy at closing time and unreliable, making sanitationman's operation intensity large, and there is potential safety hazard.Two is because back door is at poor sealing performance at closing time, in the process of moving can from gap, back door leak fluid and stench, cause secondary pollution to urban environment, citizen have strong complaints, and cause larger workload to sanitationman.For this reason, many manufacturers and knowledgeable people have carried out fruitfully R and D, but not yet have rational product to emerge so far.
Summary of the invention
In order to overcome the above-mentioned problem that existing Environmental-friendelectric electric vehicle exists, the purpose of this utility model be to provide a kind of simple and reasonable, operation uses light, good sealing effect, do not produce the Environmental-friendelectric electric vehicle rear-door opening device of secondary pollution.
The utility model solves the technical scheme that its technical problem adopts, it comprises casing, hinge, back door, back door is by the top of hinge at casing, the lateral wall of described casing is fixed with lower stator, back door is fixed with stator, air spring is hinged with between upper stator and lower stator, the upper link point of upper stator and air spring is positioned at before the lower link point of lower stator and air spring and the pin joint of back door and casing when back door is closed, the upper link point of upper stator and air spring is positioned at when back door is opened after the lower link point of lower stator and air spring and the pin joint of back door and casing.
The further scheme that this implementation is novel, the described air spring angle that its center line and vertical line are formed when back door is closed controls between 5-15 degree.
The further scheme that this implementation is novel, the described air spring angle that its center line and vertical line are formed when back door is opened controls between 20-40 degree.
After adopting said structure, the utility model has the following advantages and effect compared with the prior art: one is because the upper link point of upper stator and air spring is positioned at before the lower link point of lower stator and air spring and the pin joint of back door and casing when back door is closed, upper link point remains that one take lower link point as the thrust of the strong point, guarantee the sealing between back door and casing, thus realize the positiver sealing at back door, to efficiently solve in garbage transporting process leak fluid and distribute the problem to the secondary pollution that urban environment causes such as stench.Two is because the upper link point of upper stator and air spring is positioned at after the lower link point of lower stator and air spring and the pin joint of back door and casing when back door is opened, under the elastic force effect of air spring, ensure that back door is opened reliable, and remain certain height.Three is that haulage time is unrestricted owing to not producing leak fluid in transportation and distributing the problems such as stench, not only solves and transports the problem causing sanitationman not have enough sleep midnight, and improve the security reliability of driving.
