Description
The utility model relates to the big girder construction of the decomposable safety of a kind of electric cycle, particularly relates to a kind of disassembled big girder construction of safety of the forward and backward cross member of frame of electric cycle that is used for.
Vehicle is an indispensable running vehicle in the daily life, particularly automobile and motor bike, it almost is a part that becomes modern's life, yet, because the power actuated vehicle of fuel oils such as motor bike or automobile, ubiquity the air-polluting problem, so under the trend of doing one's utmost advocating environment protection now, the battery-driven car that has an environmental consciousness also just in response to and give birth to, for example: a kind of common electric cycle, because light easy operating, and extensively be subjected to liking of housewife, handicapped person or the elderly, now drive gradually to ride instead of walk the battery-driven car of usefulness of development short distance.
Yet, with for existing electric cycle product structure, most important, except primary power system, also to consider in not only having, the function of riding instead of walk of short distance, but also need easily carrying, promptly this electric cycle can must be moved as single-piece, yet unit body is when carrying, owing to can't do most decomposition dismounting, and cause moving difficulty.In order to overcome this difficulty, the car body of electric cycle can be changed into the connection combination of at least two sections support bodys, but the mode of how to peg graft with simple and crude chassis mobile jib realizes, cause this electric cycle unitized frame when dismantling repeatedly and reconfiguring, with cause this vehicle frame before, the back segment car body can turn round relatively around this spindle axis, make its car body bad stability, and, on the other hand, because the car body junction is also unmatched, the rear is to stable connection structure, for example: before the car body, header portion between the back segment, cause the leading portion or the back segment crossbeam top institute bonded assembly seat of this vehicle body frame, before producing when being easy to the electric cycle running, after the state that shambles, have a strong impact on that travelling of electric cycle controlled and personnel take safety, real be electric cycle one of problem extremely to be solved.
In addition, the patent that the inventor has applied for, notification number is No. 176352 " the decomposable four-wheel electric in car body chassis ride instead of walk car ", and No. the 332511st, notification number " electric cycle that can decompose the car body chassis ", all disclose and provide decomposition, unitized construction and the technology on the car body chassis of relevant electric cycle, therefore, the invention people makes the car body combination and the decomposition technique of electric cycle and structure is more convenient, firm, safety, and improved technology of creation and structure are provided further.
The purpose of this utility model is to provide the decomposable safety of a kind of electric cycle big girder construction, make the crossbeam junction of vehicle frame front and rear sections, can obtain the urgent connection of front and rear direction, make car body dismantle repeatedly, when making up, structure in the time of all can keeping making up firmly reaches accuracy rate, and helps travelling of electric cycle to control safety.
A purpose more of the present utility model is to provide the decomposable safety of a kind of electric cycle big girder construction, make this seat incorporate the crossbeam connection structure top of car body front and rear sections into, by taking advantage of person's applied force square, and make the urgent connection of front and rear direction more firm, the stability and the safety that further provide personnel to take.
The purpose of this utility model is to realize like this, promptly provide the decomposable safety of a kind of electric cycle big girder construction, it comprises one first support body, be provided with in order to operate the steering operation handle of front-wheel steering at the first support body front end, the top is provided with a connecting pin adapting pipe in its back-end, and this support body rear side lower edge place, be provided with a tie-beam, and one second support body, be carrying trailing wheel and driver train thereof, both sides respectively are provided with and a pair ofly should accept the described first support body tie-beam both end sides carrier below front end, and establish a pillar in this support body front end stage casing, the pillar front end is established an adjustment seat that can be connected with a trimming screw, the front end upside of this pillar connects a pipe, the bonded assembly adapting pipe of parallel corresponding first support body, and seat pipe the place ahead is provided with one and adjusts the lock screw, connecting pin adapting pipe by the seat pipe and first support body, a common connecting pin one end that also supplies that vertically runs through that forms vertically inserts the bonded assembly hollow pipeline, the other end of connecting pin connects seat, again by described adjustment lock screw and trimming screw respectively by behind the forward direction, and by after urgent forward on connecting pin front end and connecting pin adapting pipe rear end wall, between this first support body and second support body before, the linearly relatively and urgent connection of back extreme direction.
The advantage of the utility model device is, it is by simple and actv. unitized construction, make the vehicle frame integral body of this electric cycle, no matter be three-wheel electric cycle or the four-wheel electric car of riding instead of walk, all can be under the dismounting repeatedly of forward and backward two sectional type, assembled state, all can reach firm urgent connection and keep the whole good handling of vehicle frame, car body can not turn round around spindle axis, when personnel take, the safety that front and rear direction is not firmly rocked be can guarantee, stability and fiduciary level that the electric cycle car body decomposes, makes up further improved.
