Abstract

The invention discloses a folding type electric two-wheel and three-wheel dual-purpose vehicle. The folding type electric two-wheel and three-wheel dual-purpose vehicle is formed by jointing a telescopic two-wheel electric vehicle and a foldable wheel chair into an edge three wheel bicycle. A person sits in the side wheel chair to operate the direction by using an operating rod, and the speed braking can be achieved. The wheel chair can be quickly assembled and disassembled, and after the wheel chair is disassembled, the two-wheel electric vehicle can be singly used. The folding type electric two-wheel and three-wheel dual-purpose vehicle occupies 1 square meter when in an unfolding state, occupies 0.4 square meter when being shortened in a folding state, can be put in a trunk of a car and is matched with the car; since the person sits in the side wheel chair to operate, the gravity center is low, the vehicle is not easily turned over, the driving is safe, the sitting is comfortable, the operation is convenient, the low-carbon and energy-saving effects and the environmental-friendly effect are achieved, so that the folding type electric two-wheel and three-wheel dual-purpose vehicle is applicable to all the groups and is a standby vehicle used for ordinary families.

Description

Foldable electric two is taken turns and three-wheeled mopeds

Technical field:

The present invention relates to two and take turns and tricycle, especially can fold two and take turns and tricycle.

Technical background:

Two wheel bicycles and tricycle are the most frequently used vehicle of people, and they respectively have own performance, advantage, but also have deficiency.There are many Folding Bicycle schemes before.Relatively structure or complicated and operation inconvenience, fails widespread use so far.

Summary of the invention:

The object of the invention is to provide a kind ofly to be had two and takes turns and three-wheel dual-use function, and can fold and be convenient to collection.New traffic tool simple in structure, easy to operate.

In order to solve existing problem in background technology, the present invention adopts following technology

Scheme: the present invention adopts a kind of can stretching two to take turns battery-driven car, in its side grafting one forming limit three-wheel by fully collapsible invalid's chair.Scalable two to take turns electric vehicle structure be f-w-d, and battery controller is contained in vehicle frame front portion.Above vehicle frame rear portion, have two and parallel entablatrance, lower left side of face has a cross sill.There is a rectangle frame as rear wheel support.Horizontal back vent is fixed in rear wheel support, is welded with rack for books and newspaper above; Rear wheel support parallels connecting rod by 4 and is connected with vehicle frame rear portion entablatrance.Every two of these 4 connecting rods weld H shape with crossbeam.Trailing wheel can move forward and backward like this.The head of stumbling before the right front fillet welding of rear wheel support has, the head of stumbling after left-front corner is welded with, and below vehicle frame right side, correspondence is equipped with front spring hook, rear spring hook is equipped with in cross sill rear end.When trailing wheel pushes away forward, the snap hook head of stumbling before can automatically hooking is fixing.Throw off front spring hook, trailing wheel is toward post-tensioning, and the rear spring hook head of stumbling after can automatically hooking is fixing, is at this moment elongation state.Two take turns battery-driven car, and a hook is respectively housed before and after vehicle frame lower left, above before and after a latch is respectively housed.A wheel is equipped with on the fully collapsible invalid's chair left side, before toe board is housed, its left side is connected with the right front pin of wheelchair with latch, can turn over above, with door-inhale, fixes, the left front pin of wheelchair is welded with two heads of stumbling, during toe board horizontal direction, the left side rests stumbles on head.Below wheelchair right side correspondence be equipped with before and after block, above before and after jack is housed.During installation below wheelchair right side before and after block by the cart frame aft hook of going forward, hooked respectively, on wheelchair before and after jack aim on cart frame latch and stick in and just become limit three-wheel.Above two car front fork of electric vehicles, control lever is housed, people sits in a wheelchair, and the right hand is caught handle on control lever, brake lever, and operation drives, and turns to, and braking can.Pull open latch, on wheelchair, carry, take away the remaining cart of wheelchair and can open separately.Wheelchair is folding identical with foldable hand-propelled wheelchair.Trailing wheel is equipped with lock and is connected with brake handle by brake cable, and wheelchair side wheel also has lock, by connecting rod and toe board, and side pedal interlock.Because of the operation that sits in a wheelchair of behaving, the low difficult overturning of center of gravity.So this car advantage is traffic safety, ride comfort is easy to operate, and low-carbon (LC) is energy-conservation, environmental protection, and all kinds of crowds all use, and take up an area 1 sq m during deployed condition, while shortening folded state, take up an area 0.4 sq m, can put car trunk into, can be supporting with car.

The specific embodiment:

Below in conjunction with accompanying drawing, take demo vehicle of the present invention is described in further detail as example.Stumble after by the front H shape of front-wheel 1. motor 2. front fork 3. control lever 4. brake lever 5. handle 6 two wheel support 7. wheelchair 8. measuring wheel lock 9. side wheel 10. toe board 11. battery 12. rear jack 23. rear wheel support 24. back vent 25. first shock absorber 26. second shock absorber 27. of the front jack 22. of the seat cushion 13. aft hook 14. front hook 15. rear spring hook rear block 21. of the front block 20. of the front latch 19. of the rear latch 18. of 16. front spring hook 17. connecting rod 28. rear H shape connecting rod 29. rack for books and newspaper 30. 32. rear-wheel brake 33. trailing wheel 34. of stumbling before 31. of this car form as Figure 1-4.Two to take turns battery-driven car be before driving, and insert in front forks 3 control lever 4 lower ends, upper end dress handle, and brake lever, brake lever is connected with rear-wheel brake 33 by brake cable.Battery 12 is contained in cart frame 7 front portions, has two to parallel entablatrance above rear portion, below the left side have a cross sill, vehicle frame is equipped with snap hook 17 below 7 the right, latch 18,19 before and after being equipped with above the left side, hook 14 is housed below, 15, rear wheel support 24, stumbles 32 before right front fillet welding has, after being welded with, left-front corner stumbles 31, be welded with rack for books and newspaper 30 above, by H shape connecting rod 28,29, be connected with entablatrance.Back vent is contained in rear wheel support front portion.Trailing wheel is stumbled before pushing away forward and 32 can be hooked by front spring hook 17, is exactly that cart shortens state, and throwing off stumbles after snap hook 17 trailing wheels pull back 31 can be hooked by snap hook 16, two takes turns battery-driven car elongation state exactly.Wheelchair adopts existing foldable hand-propelled wheelchair material to strengthen, and a wheel is equipped with in left side, before toe board 11 are rectangular plates, the right is fixed on the right front pin of wheelchair with latch, it is upper that the left side rests two, the left front pin of the wheelchair head of stumbling, and can upwards turn over, and with door-inhale, fixes.Jack 22.23 before and after dress above wheelchair right side, before and after being equipped with below, block 20.21 hangs over block 20.21 on cart frame and links up with on 14.15 and with latch 18.19 insertion jacks 22.23, just become limit three-wheel vehicle again.Because wheelchair can fold, toe board is upwards dug to wheelchair and to cart, just draw close and folded up.Pull-up latch 18.19, takes away wheelchair, and cart can be used separately.
