Description

A folding electric car

technical field

The invention relates to the field of electric vehicles, in particular to a folding electric vehicle.

technical background

In recent years, with the rapid economic growth and the gradual improvement of people's consumption level, the process of automobile socialization has been greatly improved, and the automobile industry has entered a period of vigorous development by leaps and bounds. Power vehicles) have accumulated a total sales of 740,000 units so far, accounting for almost half of them in 2014. Traditional vehicles bring air pollution, so the development of electric drive is the future trend. At the same time, the lack of parking space is another big problem. Buying a car is no longer a problem for most people, but the difficulty of finding one has left many car owners in the dilemma of having a car and nowhere to park. Foldable electric vehicles, as the name suggests, are to improve the structure of the car, which can not only make the car foldable easily, but also develop the energy and power from gasoline to electricity. It can solve energy problems while saving space, and be green and environmentally friendly while solving parking difficulties. However, folding cars have not been popularized so far. The space is always limited, but there will be more and more cars, so the development of folding cars is very necessary. Replace gasoline with electricity as the power source. It is estimated that through the folding function, the length of the car itself can be reduced by 30%-40%, and at the same time, the traditional two parking spaces can be changed into three parking spaces, and the effective parking vehicles can be increased by 50%. And it does not affect other functional structures of the car. So as to solve the two major problems of energy and space at the same time.

Among the existing folding car patents, if there is a folding car (patent application number: CN 103587585 A), the stability of the car cannot be guaranteed after folding. rollover.

specific embodiment

In order to make the technical solution of the present invention clearer, the present invention will be described in further detail in conjunction with embodiment and accompanying drawing now:

As shown in Figures 1-5, the present invention also provides a folding electric vehicle, including an electric vehicle and a folding device; Steering wheel 1, front shell 2, rear shell 3, rear driving wheel 5, front part chassis 6, steering mechanism 7, arc hydraulic rod 9, trunk space 10, center shaft and bearing 11, electric motor and battery 12. Rear chassis 13. The front shell 2 and the rear shell 3 are connected through a central shaft and a bearing 11, and the front shell 2 is rotatably connected with the central shaft.

The folding device includes: a hydraulic oil tank T, a hydraulic pump P, a storage battery, an electromagnetic reversing valve and an arc-shaped hydraulic rod 9; make additional changes to the shell. The protruding rod of the arc-shaped hydraulic rod 9 is installed on the front of the electric vehicle, and the rear end is connected with the hydraulic pump and the oil tank, and is installed on the rear of the electric vehicle; the hydraulic rod has a first oil storage chamber A and a second The oil storage chamber B; the electromagnetic reversing valve has a first electromagnet, a second electromagnet and a valve core; the first electromagnet and the second electromagnet are respectively arranged on both sides of the valve core.

When the control panel receives an unfolding instruction, the control panel controls the first electromagnet to be energized, so that the first electromagnet is attracted to the valve core; when the control panel receives a folding instruction, the control panel Control the energization of the second electromagnet, so that the second electromagnet is attracted to the valve core.

When the control panel receives the deployment command, the electromagnetic reversing valve makes the first oil storage chamber A communicate with the hydraulic oil tank T through the hydraulic pump P, and the second oil storage chamber B directly communicates with the oil tank T; the hydraulic oil After returning from the second oil storage chamber B to the hydraulic oil tank T, it flows to the first oil storage chamber A through the hydraulic pump P, thereby pushing the extension rod of the arc-shaped hydraulic rod 9 to elongate, as shown in Figure 3; when the arc-shaped hydraulic pressure When the protruding rod of bar 9 was stretched to the longest state, the electric vehicle completed the unfolding action, and the electromagnetic reversing valve was de-energized. When the control panel receives a folding instruction, the electromagnetic reversing valve makes the second oil storage chamber B communicate with the hydraulic oil tank T through the hydraulic pump P, the first oil storage tank A directly communicates with the hydraulic oil tank T, and the hydraulic oil Return from the first oil storage chamber A to the hydraulic oil tank T, and then flow to the second oil storage chamber B through the hydraulic pump P, so that the extension rod of the arc-shaped hydraulic rod 9 is shortened, and the front of the electric vehicle is pulled up and aligned with the pulling force. The ground is at an angle, and when the angle reaches 50-70°, the electromagnetic reversing valve is powered off, and the extension rod of the arc hydraulic rod 9 is no longer shortened, and the folding of the vehicle is completed.

The above-mentioned folding electric vehicle realizes the folding function of the electric vehicle, reduces the area occupied by itself when parking, and greatly increases the number of effective parking. Moreover, the structure of the modified folding device is relatively simple, the function reliability is relatively strong, the structure of the vehicle is not greatly changed, and it can be applied to traditional electric vehicles, and can also be applied to the use of rear-drive vehicles. Therefore, the battery, engine and battery of the electric vehicle can be placed in the rear, the weight of the front of the vehicle is greatly reduced, and only the steering mechanism needs to be set at the front of the vehicle, thus ensuring the flexibility of the vehicle steering, and the rear of the vehicle is not foldable It ensures that the storage space at the rear of the vehicle will not be damaged.

Further, in this embodiment, the electric vehicle is equipped with two folding seats 8, which are respectively installed in the driving position and the co-pilot position. When the electric vehicle is folded, the backrest of the seat can be folded toward the seat cushion, so that the backrest Does not interfere with the trunk.

Further, the outer diameter of the front housing 2 of the electric vehicle is smaller than the inner diameter of the rear housing 3 , and when the front of the electric vehicle is lifted, the front housing 2 is partially accommodated in the rear housing 3 .

The electric vehicle also includes a support rod 4 , which is arranged at the bottom of the electric vehicle and on both sides of the central shaft and the bearing 11 . Therefore, when the front part of the electric vehicle is folded up, it plays an auxiliary supporting role.

When the car enters the parking lot and needs to be parked, the driver gets off the car and can control the front of the vehicle to fold around the central axis 11 through a remote control device (not shown). After a certain support, the front shell 2 of the car is pulled up by the arc-shaped hydraulic rod 9, folded at a certain angle around the central axis 11, and can be placed in the rear shell 3. When the lifting angle reaches about 50°-70° Stop automatically when, simultaneously seat 8 in the car also folds automatically so that the seat back can not rotate towards the rear of the car, and the power is cut off, finally reaching the purpose of reducing space. At this time, if the front part of the folding electric vehicle is lifted by 70°, then the lateral space is reduced by 33% of the length of the vehicle. When the car is to be used, the electric car is put down the front part around the central axis 11 through the remote control arc hydraulic lever 9 of the external device, and the seat 8 is also restored to the original state at the same time. Lifting will only interfere with the ground, and finally the whole vehicle will return to its original state.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of changes or modifications within the technical scope disclosed in the present invention. Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
