The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of electric bicycle ladder, comprises support 1, clamping plate 2, roller 3, connecting arm 4 and retracing spring 5.The top of clamping plate 2 offers connecting bore, and is connected with the wheel shaft of back wheels of vehicle by this connecting bore, and the bottom of clamping plate 2 is connected with the top of support 1 with first bearing pin 6 by a catch, and clamping plate 2 are fixed between support 1 and the catch by first bearing pin 6; Clamping plate 2 are provided with deep-slotted chip breaker 7, deep-slotted chip breaker 7 is positioned at the below of first bearing pin 6, pass deep-slotted chip breaker 7 be provided with second bearing pin, 8, the second bearing pins 8 can fixed support 1 and catch, and can slide along deep-slotted chip breaker 7 when clamping plate 2 second bearing pin 8 when first bearing pin 6 rotates with respect to support 1.Deep-slotted chip breaker can be designed as 75-100 °.In the lower end of clamping plate 2 and be provided with flange below deep-slotted chip breaker 7, flange is set to can connect and fix connecting arm 4 when clamping plate 2 and connecting arm 4 relatively rotate certain angle.Connecting arm 4 is positioned at the below of clamping plate 2, is connected in the top of support 1 on it by croisillon de joint homocinetique 9, and its lower end is connected with clamping plate 2 by retracing spring 5.Retracing spring 5 can be a cylindrically coiled spring.Roller 3 is arranged at the lower inside of support 1 by link span 10, a wherein inboard side that refers near car body.
The use and the principle of work of the electric bicycle ladder in the present embodiment are as follows: when parking battery-driven car, stir the support 1 of car ladder downwards with pin, make support 1 around axially rotation down, before the tail end of support 1 is about to contact to earth, because roller 3 is arranged at the lower inside of support 1, therefore roller 3 can at first contact to earth before the end of support 1 contacts to earth, this moment, whole car ladder contacted with ground formation roller, thereby only need gently to carry vehicle body to the back upper place, the trailing wheel of battery-driven car is promptly propped and is broken away from ground, can realize parking of battery-driven car easily.This moment, the lower end with connecting arm 4 dialed to left braking position left, and retracing spring 5 is in the state of stretching, and it is safe that battery-driven car 5 is parked.When state is parked in releasing, the lower end of connecting arm 4 is dialed to right braking position to the right, go-cart forward simultaneously, the car ladder is whole upwards to rotate, and the tail end of support 1 rises, and battery-driven car is in the non-state of parking, and the car ladder is in release position.
What is more important because the weight of general battery-driven car is bigger, promotes effort when trailing wheel does not have gas, bring inconvenience to the user.Electric bicycle ladder among this embodiment, by flange being set in clamping plate 2 bottoms, when tire does not have gas to carry out, earlier connecting arm 4 is depressed and be in left braking position, prop up the cycling start ladder then, the upper edge of connecting arm 4 fixes on the flange that is provided with below clamping plate 2 automatically, make connecting arm 4 and clamping plate 2 temporarily be in can not relative motion state, and because the fixing effect of connecting arm 4 and clamping plate 2, can not continue upwards to rotate by the 3rd pin 9 bonded assembly supports 1 with connecting arm 4, this moment, the trailing wheel of battery-driven car was liftoff, land and supporting car body and be fixed in two rollers 3 on the support 1, become the ccasual trailing wheel, made things convenient for battery-driven car when the back tire does not have gas, promotion when especially bearing a heavy burden.The clamping state of visible as shown in Figure 3 clamping plate and connecting arm.
As can be seen from the above embodiments, the roller that is fixed on the support plays double effect, and the first has been saved by itself and ground-surface friction of rolling and to have been parked the required bigger strength of mentioning vehicle of battery-driven car in the process of vehicle parking; It two is when the battery-driven car rear tyre does not have gas, by the fixing effect of connecting arm and clamping plate, has stoped upwards rotating of support, makes that the roller on the support can supported cart ladder weight replace trailing wheel, the convenient promotion temporarily.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
