Description
Technical field
The utility model proposes a kind of electric unicycle, there is the feature of centre of gravity.People only need to stand on pedal and just can ride, it is not necessary to fix leg and vehicle body with other device such as leg plate or guide carriage.When riding, leg is more comfortable, runs more stable.
Background technology
Electric unicycle is familiar with by everybody as a novel vehicles, a wheel hub motor provide the wheel of power to contact with ground.People stands in and moves forward on pedal, and in motion process, people can keep the balance of left and right directions.The balance of fore-and-aft direction is to be completed by a main circuit control panel being assembled with gyroscope and acceleration transducer, when vehicle body leans forward or during hypsokinesis, sensor provides signals to wheel hub motor after the microprocessor processes that signal passes through on master control borad being detected, allow motor have an acceleration forward or backward, before and after making wheelbarrow, keep balance.
Electric unicycle is power-actuated, except wheel hub motor, vehicle frame, foot-operated in addition to, in addition it is also necessary to be furnished with power supply and main circuit control panel.Power supply is made up of Li-ion batteries piles and lithium battery protection board, and common power supply is to be packaged into an overall also referred to as battery bag.Electric unicycle before this, battery bag and master board be all mounted in the top of wheel hub motor, and the center of gravity of car is higher.The center of gravity of car raise after just as people steps down on stilt, simply the contact of sole and one tie point of pedal is difficult to stable manipulation electric unicycle the most freely.
Old and (Shane Chen) Application No. CN201110089122.9 Chinese patent refer to Chinese ancient acrobatics and " walks on stilts ", will drive electric unicycle and China's " stilt walk " compares.Stilt walk has double lifting up and dividing of singly lifting up, and principle is just as.We lift up as example with double, and the pin of operator steps down on stilt, and every leg also needs to and corresponding stilt colligation, forms two fixing tie points so that operator and stilt become an entirety, keep a common center of gravity with the vertical direction on ground.In a word, between leg and stilt, only one of which tie point can not play stilt, in like manner, driving high center of gravity electric unicycle only has the connection of pin and one point of pedal to be highly difficult, leg also needs to have individual fixing with vehicle body, make driver and vehicle body become an entirety, direction perpendicular to the ground keeps a common center of gravity.
The United States Patent (USP) (Motorized Transport Vehicle for a Pedestrian, US20090266629) of Simeray et al. application solves this problem in the early time.The patent proposes the guide carriage that is provided above at foot pedal, shaft-like or cuff-like bracket tightly clips the leg of driver, and driver is the most fixing with vehicle body, becomes an entirety, provides bigger stability to driver.But, the guide carriage gripping leg also limit the motion of leg, and when operator needs quickly to get off, guide carriage can hinder the action of driver, and it may be dangerous for bringing some inconvenience even some occasion.
Old and (Shane Chen) Chinese patent (Application No. CN201110089122.9) above-mentioned, and its United States Patent (USP) (Patent No. US20110220427A1) improves on the basis of the patent of Simeray.Propose and be provided above a leg plate being connected with car body at foot pedal, effect be the leg enabling driver against car body, in addition to foot pedal, add a fixed connection point.Replace the guide carriage in Simeray patent with leg plate, overcome the guide carriage inconvenient and that may be present potential safety hazard in driving procedure.
Leg plate has following two features: 1, leg plate surface substantially protrudes from one height of vehicle body side, and what when making driver stand on pedal, leg was inevitable is close to leg plate.2, leg plate is laminating leg, and surface is the most slightly concave curved surface, and is made up of the material of certain frictional force.The purpose of the two feature is exactly to allow leg plate have a connection function with the leg of people, matches with the tie point of pin and pedal.Its advantage is apparent from, and in increase, this tie point of leg plate makes stable driving electric unicycle become a reality possibility, and the success of commodity developing also demonstrates that it is practicable.
But also occurring in that new problem, leg plate is not as the leg of guide carriage such banding people, but one has the laminating rubbed back and forth, the short time, the driver that rides once in a while perhaps will not feel the discomfort of leg, and driving leg has and feels pain for a long time.Also illustrate that guide carriage and old and (Shane Chen) the leg plate of Simeray are respectively arranged with merits and demerits.How to overcome the shortcoming both them, really allow driving wheelbarrow become more convenient the most comfortable freely.
Guide carriage or leg plate can be need not？Or talking about from stilt walk, why stilt must could walk by two tie points, people on foot time be that sole lands and need not two tie points, the whether reason of stilt center of gravity height.We imagine patients with amputation, mix artificial limb to patients with amputation, and artificial limb is also that machinery is similar with stilt.People has no idea as the leg each link that the most flexibly manipulate artificial limb the same with pin of manipulation oneself, but also has only to a tie point during walking.Illustrate it is not the how many problem of tie point, but center of gravity is the highest the highest to tie point force request.The center of gravity of stilt is higher, and only pin and one point of stilt is fixing, and stress is inadequate, in addition it is also necessary to the colligation at other position is just provided that enough dynamics.Center of gravity is the lowest the lowest to tie point force request, if it is possible to reducing the center of gravity of wheelbarrow, guide carriage and leg plate are the most inessential.
The utility model is to overcome above-mentioned patent and the shortcoming of the electric unicycle of proposition in patent application, it is proposed that a centre of gravity electric unicycle, allows electric unicycle need not guide carriage or leg plate also can more be stablized, comfortable driving freely.
Utility model content
As it was previously stated, the utility model is the technical deficiency overcoming existing patent and product, it is proposed that a centre of gravity electric unicycle.In order to solve above-mentioned technical problem, the utility model is achieved by following two key technology scheme:
First, novel axletree vehicle frame fixed form.Axletree two ends have spline plane to be kidney-shaped shape shaft, do not have thread；Also there is the mounting hole identical with axletree two ends shape vehicle frame upper end, and the top in hole has a gap cut open, the direction perpendicular with this gap plane to be drilled with screw hole；After left and right vehicle frame waist-shaped hole is installed to axletree two ends, screw is slowly tightened through the nut of screw hole with opposite, and vehicle frame and axletree are the most fixing.This kind of structure is compared and is used more wedge vehicle axle lock locking structure (Chinese Patent Application No.: 201220510358.5) part more succinct in the market, and installing/dismounting is the most more convenient.The more important thing is the vehicle frame comparing wedge locking mechanism, the upper end of vehicle frame is short a lot；Vehicle body side has just vacated more space, the parts being originally placed on wheel hub motor top is put into Vehicular side body and is possibly realized.
Second, battery bag uses the method for partition packing, is separately mounted to the scattered space of electric unicycle side.Vehicle body side is unlike the top of wheel, and its space is limited.Original battery bag packing manner is that all batteries and lithium electric protection plate are packaged into a parcel.Such a bigger parcel can be only installed at above wheel hub motor, and the center of gravity of wheelbarrow is the highest.After the partition packing of battery bag, it is possible to its dispersion is installed to the lower Vehicular side body being close to axletree of center of gravity, greatly reduces the center of gravity of vehicle body.After the center of gravity of wheelbarrow reduces, tie point stress is the least, drives wheelbarrow just unlike stilt walk is so difficult, it is not necessary to guide carriage or leg plate also can stablize manipulation wheelbarrow freely.This invention also brings a new innovation achievement, and after the dispersion of battery bag is installed, the width of vehicle body reduces, thinner than vehicle body in the market；Improve the comfortableness of driving.
Additionally the utility model also add the design of wheelbarrow inner casing.On market, overwhelming majority wheelbarrow is all a shell, and battery bag and circuit control panel are typically directly arranged on inner surface of outer cover or outer surface, then cover with cover plate.Only it is difficult to accomplish the most waterproof by cover plate.The present invention uses a totally enclosed inner casing, and battery bag and circuit control panel are arranged on outside inner casing, and then outside shell covers.So design water resistance be greatly improved, particularly by tire get rid of into the ponding from road surface can stop completely.
