Lifting device for batteries of electric automobile frame
Technical field
The utility model relates to a kind of lifting device, relates in particular to a kind of lifting device for batteries of electric automobile frame.
Background technology
The requirement of and environmental protection in short supply along with world energy sources, the automobile that gasoline and diesel oil is the energy of take has been subject to certain restriction and impact, the electronlmobil of environmental protection and energy saving becomes an important branch of auto trade, and electronlmobil has just in time met the double requirements of saving the energy and environmental protection.In electronlmobil, battery is crucial parts, and the rational deployment of battery and installation can provide larger power to electronlmobil.In order to save battery installing space, electronlmobil is in the past generally by screw, the battery frame installing to be in advance fixed on car chassis, while changing battery, first need battery frame to remove, taking out battery pack changes again, not only dismounting is wasted time and energy, and operation is loaded down with trivial details, work capacity is large.Existing electronlmobil is often by battery frame both sides, lifting device being installed respectively, and when changing battery, battery frame rotates an inclination angle by the such device of battery frame lifting mechanism, battery pack is imported and exported and be tilted to, and facilitates battery pack to come in and go out.Yet in the process of rising and falling at battery frame, the lifting device of both sides there will be asynchronous or monolateral lifting device load to double overweight phenomenon of the failure, cause oil cylinder distortion, piston and bar are stuck, and the electric current ablation motor switch that surges, exists shorter defect of potential safety hazard and service life.
Summary of the invention
The utility model is in order to overcome deficiency of the prior art, provide a kind of simple in structure, that operation is used is time saving and energy saving, battery altering is conveniently for the lifting device of batteries of electric automobile frame, solved the battery disassembly and assembly that exists in prior art change waste time and energy, operation is loaded down with trivial details, efficiency is low, work capacity is large, the lifting device poor synchronization of both sides or monolateral lifting device load double overweight, cause oil cylinder distortion, piston and bar are stuck, the electric current technical matterss such as ablation motor switch of surging.
To achieve these goals, the utility model is by the following technical solutions: a kind of lifting device for batteries of electric automobile frame of the present utility model, comprise lifting motor, described lifting motor is connected with oil pump, described oil pump is connected with oil bag, the both sides of battery frame are respectively equipped with the one or three grade of oil cylinder, the two or three grade of oil cylinder, described the one or three grade of oil cylinder, the bottom of the two or three grade of oil cylinder is provided with base plate, described base plate is provided with oil duct, described the one or three grade of oil cylinder is connected with oil bag, described the one or three grade of oil cylinder, connection hydraulic fluid port on the two or three grade of oil cylinder is connected by oil pipe respectively, described the one or three grade of oil cylinder, the top of the two or three grade of oil cylinder is connected by strut bar assembly, described strut bar assembly is arranged at the bottom of battery frame.Battery frame open front, battery frame rear portion arranges rotating shaft and is connected with electronlmobil, wherein, in the both sides of battery frame, be respectively equipped with the one or three grade of oil cylinder, the two or three grade of oil cylinder, the top of the one or three grade of oil cylinder, the two or three grade of oil cylinder is connected by strut bar assembly, and described strut bar assembly is arranged at the bottom of battery frame, and what make battery frame rear portion arranges rotating shaft in conjunction with lifting device, in lifting device lifting, battery frame is imported and exported and is tilted to, and facilitates battery pack to come in and go out.Connection hydraulic fluid port on the one or three grade of oil cylinder, the two or three grade of oil cylinder is connected by oil pipe respectively, makes the one or three grade of oil cylinder, the two or three grade of oil cylinder can be synchronous in lifting.When being opened for to motor switch when " rise ", lifting motor drives oil pump pump oil, oil synchronously rises three grades of oil cylinders on both sides from the oil duct of base plate to upper punch, the rotating shaft that arranges due to battery frame rear portion, when battery frame middle part is by lifting, the rotating shaft at battery frame rear portion will make battery frame import and export be tilted to, and facilitates battery pack to come in and go out.When motor switch is opened for " decline ", motor reversal, by the oil pump oil return bag in oil cylinder, three grades of oil cylinders are synchronously fallen, and realize the decline of battery frame.Meanwhile, when oil pressure is greater than setting value, oil pump Self-tipping, plays a protective role.
As preferably, described strut bar assembly is fixedly arranged on the bottom of battery frame by adapter plate, and described adapter plate forms the groove that can mate with strut bar assembly.
As preferably, the size of described groove is greater than the external diameter of strut bar assembly.Wherein, the size of groove is greater than the external diameter of strut bar assembly, and making strut bar assembly be equivalent to adapter plate has certain degree of freedom, is convenient to battery frame and in lifting, forms an inclination angle making progress.
As preferably, described the one or three grade of oil cylinder, the two or three grade of oil cylinder are arranged at respectively the middle part of battery frame both sides.Wherein, the one or three grade of oil cylinder, the two or three grade of oil cylinder are arranged at respectively to the middle part of battery frame both sides, in lifting, make the stressed more rationally rising of battery frame more steady, more can coordinate rotating shaft to make battery frame form an inclination angle making progress.
As preferably, described oil pump is provided with by pass valve.When system pressure increases, can make traffic demand reduce, now by pass valve is opened, and makes the unnecessary flow oil return bag that overflows, assurance by pass valve entrance pressure, oil pump delivery pressure is constant, plays level pressure overflow effect, voltage stabilizing, system unloaded and safety guard-safeguard effect.
As preferably, described in have oil pipe to become concave character type structure.Oil pipe adopts copper pipe, oil pipe is designed to concave character type structure and in order to adapt to strut bar assembly, is convenient to location without fixing by other parts, simple and convenient reducing the cost.
As preferably, described oil pipe is arranged at the below of strut bar assembly.Wherein, oil pipe is arranged to the below of strut bar assembly, has avoided oil pipe to be exposed to the outer end of battery frame, what change battery, can not cause unnecessary interference in time.
Therefore, the utlity model has following beneficial effect: simple in structure, that operation is used is time saving and energy saving, make battery pack fetching process easily laborsaving, convenient and swift, reduced workman's labour intensity, improved production efficiency, the oil cylinder of both sides can reach the effect of synchronous lifting, avoid that double-motor is asynchronous and to occur that monolateral load doubles overweight, oil cylinder Deformed piston and bar are stuck, the electric current motor switch ablation problem that surges.
