Description

Detachable back-rest for motorcycle

The utility model relates to depending on of a kind of support rider back that is arranged on the motor bike afterbody.

Existing motor bike all is not provided with the frame of depending on of support rider back.This is for taking the person of taking on back seat, because back does not have land, only armrest often easily causes high-pressure to the support of vehicle body, lacks the sense of security, particularly when running at high speed.This advancing at utmost speed and back does not have the fatigue that the sight of depending on also very easily causes human body.

The purpose of this utility model is to provide a kind of extendible motor bike of safety and comfort to depend on for the above-mentioned deficiency that overcomes prior art.

The extendible motor bike of realization the purpose of this utility model is depended on by underframe, is leaned against with pull bar and form, described underframe comprises two sleeve and horizontal installation connecting panels that are connected between two sleeves along the setting of vehicle body axially parallel, the front end of sleeve is provided with a connector that can be connected with shock structure hold-down bolt behind the motor bike, and the rear end is an open end; Described leaning against comprise and lean against body and two strut bars that be arranged in parallel, and an end of strut bar is with to lean against body affixed, and the interior short slide bar of sleeve is hinged and sleeve is advanced in folding and unfolding but the other end and is sleeved on; One end of pull bar is with to lean against strut bar hinged, and the other end joins by the sleeve body of an adjustable connection structure and underframe.Connector by barrel forward end can be connected with the back shock structure hold-down bolt of motor bike the utility model with the horizontal installation connecting panel that is connected between two sleeves with the back seat mounting, to lean against strut bar during use pulls out upwards from sleeve and digs, that end that joins with sleeve of pull bar is placed the appropriate location and makes it fixing, lean against strut bar, underframe and pull bar three and then constitute a stable triangular structure and make to lean against reliably and prop; But being connected between time spent releasing lever and underframe not, will leaning against and fall and in its strut bar propelling sleeve.

The utility model is simple in structure, manufactures easily, and is easy to use, but without the fashion folding and unfolding, do not influence the original style and features and the performance of motor bike, can be used for all kinds of motor bikes.

Below in conjunction with embodiment and accompanying drawing the utility model is described in further details.

Fig. 5 is for leaning against the folding and unfolding constitution diagram

Fig. 6 is a use scheme drawing of the present utility model

Shown in Fig. 1～5, in the present embodiment, its underframe comprises two sleeves that be arranged in parallel 1 and 2, the horizontal installation connecting panel 3 that is connected between two sleeves, is provided with a connector 4 that can be connected with shock structure hold-down bolt behind the motor bike at the front end of sleeve; Lean against and comprise and lean against body 5 and two parallel strut bars 6,7, an end of strut bar is with to lean against body affixed, and the short slide bar 8 that the other end and is sleeved in the sleeve is hinged; One end of pull bar 9 is hinged with the epimere portion that leans against strut bar, the other end is then realized being connected with the adjustable of underframe sleeve by a screw rod pin 11 that is through in the slotted eye of the groove shape connecting panel 10 that is fixed on the sleeve body, thus with lean against strut bar, underframe and constitute a stable triangular structure jointly and will lean against body and prop.An opening end socket 12 can be set at the open end of sleeve and on short slide bar, displacement and the location that a unidirectional retaining spring card 13 limits short slide bar be set.

Also can adopt other some common versions such as chute structure to realize adjustable connection between pull bar and underframe as pin, pore structure, band positioning rank; Coat some soft- bodies 14,15 at pull bar on the body with leaning against, can strengthen the comfort of its contact.The connector of barrel forward end also can design forms such as pore-forming, draw-in groove according to different mounting meanss.
