Detailed description of the invention
Take turns three-wheeled electric vehicle embodiment referring to figs. 1 through Fig. 4 to the utility model changeable two to be described further.
See Fig. 1 to 4, a kind of changeable two take turns three-wheeled electric vehicle, comprise axle drive shaft 1 and car body 6, described axle drive shaft 1 is removably connected with stationary hub 2, described axle drive shaft 1 one end is provided with cavity 12, described cavity 12 is arranged with link span 5, described cavity 12 sidewall is provided with limiting section, described limiting section restriction link span 5 moves axially, described link span 5 is rotatably connected to extending shaft 3, described extending shaft 3 is removably connected with movable wheel hub 4, described link span 5 is provided with hole clipping 52, described extending shaft 3 is provided with fixture block, described fixture block and hole clipping 52 clamping, described extending shaft 3 is provided with lockout mechanism, when extending shaft 3 and axle drive shaft 1 concentric, described lockout mechanism is fixedly connected with extending shaft 3 and axle drive shaft 1, described car body 6 is provided with fixed part, when movable wheel hub 4 does not use, described fixed part fixes extending shaft 3.
Compared to current battery-driven car, by arranging an extending shaft that can fold 3 at axle drive shaft 1 place, and dismounting is connected with movable wheel hub 4 on extending shaft 3, make battery-driven car can according to driver demand, random switching two is taken turns and is travelled or three-wheel traveling, when needs travel for three-wheel, extending shaft 3 is only needed to rotate, after extending shaft 3 and axle drive shaft 1 concentric, with lockout mechanism fixed drive axle 1 and extending shaft 3, now, battery-driven car can travel by three-wheel, when only needing two to take turns traveling, extending shaft 3 is only needed upwards to overturn, when extending shaft 3 and car body 6 are fixed, structure is simple, easy to operate.
See Fig. 1, when battery-driven car uses three-wheel to travel, extending shaft 3 overturns, concentric with axle drive shaft 1, extending shaft 3 is fixed with two claws 31, by claw 31 respectively with draw-in groove 11 clamping on axle drive shaft 1, extending shaft 3 and axle drive shaft 1 clamping, extending shaft 3 is fixed, the rotation of axle drive shaft 1 drives extending shaft 3 therewith to rotate, and the wheel hub now on extending shaft 3 rotates along with extending shaft 3, and battery-driven car now uses three wheels to travel, stability improves, and is suitable for the elderly or child's driving.
See Fig. 2, when battery-driven car uses two-wheeled to travel, pull the claw 31 on extending shaft 3, claw 31 is separated with draw-in groove 11, then upwards extending shaft 3 is overturn, turned over by extending shaft 3 after turning 90 degrees, the jumping bean spring 34 on extending shaft 3 and hole clipping 52 clamping on link span 5, make extending shaft 3 be fixed, the normal traveling of battery-driven car can not be affected, battery-driven car is travelled by three-wheel and switches to two to take turns traveling, reduces the friction drag on tire and ground, improves the acceleration/accel of battery-driven car.
See Fig. 3, car body 6 is provided with claw 31, extending shaft 3 is provided with hold down groove 32, when extending shaft 3 upwards overturns, after jumping bean spring and hole clipping 52 clamping, pull claw 31 and hold down groove 32 clamping, extending shaft 3 is fixedly connected with car body 6, now link span 5 is also fixed, link span 5 is separated with the cavity 12 of axle drive shaft 1, the rotation of axle drive shaft 1 can not affect link span 5, make battery-driven car normal two can take turns traveling, it should be noted that other structures that can also have of fixed part realize herein, such as car body 6 is provided with hook, extending shaft 3 is provided with hook hole, described hook and hook hole snapping, but consider the stability of structure, the scheme that preferred the present embodiment adopts.
See Fig. 4, axle drive shaft 1 is provided with cavity 12, position-limited trough 13 is provided with in cavity 12, link span 5 is sheathed in cavity 12, the sidewall of link span 5 is provided with limiting stopper 53, limiting stopper 53 coordinates with position-limited trough 13, prevent moving axially of link span 5, one end of link span 5 is provided with through hole 51, through hole 51 is hinged with the rotating shaft 33 of extending shaft 3, hole clipping 52 is provided with below through hole 51, when battery-driven car two takes turns traveling, hole clipping 52 and the jumping bean spring clamping on extending shaft 3, thus fixing extending shaft 3, link span 5 is separated with the inwall of axle drive shaft 1, so the axial rotation of axle drive shaft 1 can not drive link span 5, thus two of battery-driven car can not be affected take turns normal traveling.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
