Description

Multi-purpose folding bicycle

Technical field

The utility model belongs to scalable or the Foldable bicycle field, relates in particular to a kind of multi-purpose folding bicycle that can be used as bicycle and goods go-cart use.

Background technology

Bicycle with folding functional is ridden easily the characteristics except that having ordinary bicycle, its volume after folding is little, the parking space that takies is less, can also be convenient to trip and carry, transports or deposit with the passenger traffic instrument, therefore obtains promotion and application more and more widely.The folding mode of folding bicycle is varied, and the doubling of car beam is the folding mode that generally adopts, and the bicycle after folding can only carry or deposit as luggage, needs manpower to guide and support or could move pickaback after folding.For addressing the above problem, people design and develop out the folding bicycle with multiple function, being about to folding bicycle makes it possess the hand push function after by the middle part doubling, but because two wheels walk abreast but can not coaxially move, poor reliability, because the forward and backward wheel of vibration breaks away from easily, influence the use of its hand push function simultaneously.

On December 28th, 2005, the Chinese patent ZL 200420112425.3 of bulletin provided a kind of hand push packed bicycle, it is characterized in that: folding device is housed in the middle of single camber beam, folding device is combined by two folder, the folding device folding direction is one anti-one just, two lock pins are arranged on folding device, when pull up lock pin folding after, front and back wheel is finished two 90 ° big and is turned, steady arm is tightened front wheel spindle and hind axle by handle, and steady arm couples together front wheel spindle and hind axle diaxon.Simple, the folding back of this bicycle structure two wheels are coaxial fixing, but effectively improved the handling of two wheels when carrying out.But also there is following shortcoming in the packed bicycle of this hand push: when using as go-cart, have only coaxial two-wheeled to support car body, behind lade, because the front and back length of car body is shorter, be easy to cause that car body leans forward or hypsokinesis in the implementation; On the other hand, do not bear cargo stage on the car body, can't steadily place, can't realize the super performance that hand barrow has for rapid wear or box article.

The utility model content

The purpose of this utility model provides a kind of multi-purpose folding bicycle, and it not only can be used as the instrument of riding normally, and can use as small-sized go-cart after folding, the super performance such as safe, steady of realizing that go-cart had.

For realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is as follows:

A kind of multi-purpose folding bicycle, comprise folding device, the car beam, the car body that driver train links to each other with the Che Liang two ends, car body comprises front vehicle body or aftercarriage, described front vehicle body comprises preceding standpipe, the front-wheel of front fork and front fork lower end, one end of car beam is captiveed joint with preceding standpipe, described aftercarriage comprises rear profile tube, the trailing wheel of back vent and back vent lower end, an other end of car beam is captiveed joint with rear profile tube, the folding position of folding device is arranged on Che Liangshang, it is characterized in that described multi-purpose folding bicycle also comprises at least one shelf of being located on the car body, connection is provided with auxiliary wheel on the described car beam.

Concretely, the described shelf of this multi-purpose folding bicycle are the rearmounted shelf of being located on described rear profile tube or the back vent, perhaps for being located at the preposition shelf of described preceding standpipe or car beam front end.

Described shelf are the preposition shelf of being located at the rearmounted shelf on described rear profile tube or the back vent and being located at described preceding standpipe or car beam front end.

One end captive joint rear profile tube of described rearmounted shelf, the support body of rearmounted shelf is connected with the back vent anchor shaft by supporting vertical rod.

Described preposition shelf are movable pull shelf, and described pull shelf are made up of the pumping rod of suit in support body that chute is set and the chute, and described support body or pumping rod and preceding standpipe or car beam leading section are fixed.

Described rearmounted shelf and preposition shelf isoplanar are provided with.

Described car beam is for directly to establish the folding device position of single-beam or car beam for directly establishing beam structure.

Described folding device is made up of the fold mechanism that is arranged on the car beam, and fold mechanism is made up of articulation piece and movable lock pin, and the steady arm that connects two axles is set on described front-wheel or the hind axle.

Described folding device is the fold mechanism that is provided with on the car beam, and described front vehicle body or aftercarriage are provided with the registration device that is connected and fixed forward and backward car body.

Described auxiliary wheel is a cardan wheel, and cardan wheel is hung on car beam below.

On the car beam of this multi-purpose folding bicycle folding device is set, folding device can be the device for folding that single lap mechanism or twofold mechanism form, if adopt twofold mechanism, forward and backward car body can be folded to form the go-cart form of the coaxial setting of front and rear wheel, the wheel between centers of front and rear wheel can be provided with steady arm and connect diaxon, to strengthen the handling of front and rear wheel.If single lap mechanism, forward and backward car body can be folded to form the V-shaped go-cart form of front and rear wheel, and forward and backward car body connects by the registration device that connects forward and backward car body.Auxiliary wheel is transferred at folding back car beam-ends it is contacted to earth, and auxiliary wheel can be one or two, adopts an auxiliary wheel can form three wheel barrows with front and rear wheel as the strong point.Rearmounted shelf and preposition shelf are after folding, be combined to form the bigger bearing table of a bearing surface, and can stablize firm placement not to be stowed under heavy cargo, rapid wear or box-type goods, make front-wheel, trailing wheel stressed evenly, can effectively prevent the place ahead landing of carrier from three wheel barrows, stability, turning to property and delivery performance improve.Standpipe or car beam front end before preposition shelf can be arranged on, the drawer type activity shelf that it can be made up of chute and slide bar also can be collapsible shelf, do not influence performance as cycling the time.Auxiliary wheel is suspended on Che Liangxia as cycling the time, can not influence the commentaries on classics of pedaling of driver train.When bicycle car beam lower position was provided with, auxiliary wheel can directly be fixed on Che Liangxia; When bicycle car deck-molding position is provided with, can auxiliary wheel be hung on car beam below by pipe link.

The folding device that this multi-purpose folding bicycle adopts can be existing single lap or twofold mechanism folding device.The inter-agency Che Liangshang that is arranged at a certain distance of twofold.Fixedly the connection vertical rod of auxiliary wheel is fixed on the car beam between two fold mechanisms, and when being folded to form go-cart, the car beam between two fold mechanisms can be used as handle and uses.

Handlebar and saddle can be removed during stored collapsed, need not other change promptly can be whole packed.

The beneficial effects of the utility model are that this multi-purpose folding bicycle is simple in structure, reasonable in design, have given full play to the function of bicycle as hand barrow, can conveniently ride as bicycle, can form the loading go-cart again, bearing goods is stable, firm, and implementation is steady, handling is good.
