Description

[0001] Technical Field: It relates to the technical fields of new energy electric vehicles and motor technology.

[0002] Background Art: Usually, a car can only be regarded as a means of transportation for one person. For a human body weight of only over a hundred catties, it has to carry an average car mass of about one and a half tons. This fully shows that passenger cars are heavy in weight and load, which is supported by the extreme consumption of resources and energy. It is a measure taken out of necessity under the existing technology and is extremely unfavorable for sustainable development. To solve this problem, the present invention proposes the "Tiger Tally-style Light Electric Vehicle and Double-wheel Mid-mounted Motor" solution.

[0003] Summary of the Invention: Based on the double-wheel mid-mounted motor technology and combined with the lightweight design concept, the present invention innovates the main parts of an electric vehicle such as the frame, body, seat, and running parts. Without pursuing excessive power settings and with a suitable and sufficient power matching, it creates a new type of light electric vehicle with kinetic energy recovery power generation.

[0005] Detailed Description of the Invention: To innovate an electric vehicle, it is necessary to start from the main aspects of the vehicle and make improvements different from the existing technology in terms of structural design and material selection. Taking a three-wheel electric vehicle as an example: Start the improvement from the motor, make both ends of the motor rotor shaft extend outside the two end covers, and insert the two ends made into semi-axle splines into the spline reservoirs in the centers of the two brake discs. Then, make a technical connection with the two wheels through the screws on the brake discs. In this way, the preparation process of the double-wheel mid-mounted motor is completed.

[0006] The double-wheel mid-mounted motor for the front wheel of a three-wheel electric vehicle needs to be fixed by a semicircular cylindrical tile structure made of two parts, upper and lower. The edges of the joints of the upper and lower fixing frames are provided with screw holes for fixing when the upper and lower parts are clasped together. The upper fixing frame is provided with a brake caliper seat near the edge of the brake disc, and a fork seat for fixing the front fork is provided in the middle, and the front fork made of two shock absorbers with coil springs is fixed on it (the micro-sized front fork can be without coil springs). The two-wheeled and three-wheeled electric vehicles in the prior art all use the two front forks to fork the wheels in the middle to control the steering of the wheels, while what the present invention does is to fork the motor in the middle to turn the wheels in the front and back. (The two front forks can be small on the top and large on the bottom, and are outwardly tilted to ride on the motor) The fork frame above the front fork is used to fix the shock absorber. In addition to installing the front fork, a steering shaft is also installed on it. The steering shaft passes through the steering shaft tube and the pressure bearing on the frame and is connected to the steering wheel or the steering handle. In this way, a traveling device for the front wheel that integrates multiple technical combinations such as power, traveling, steering, shock absorption, braking, etc. is completed. The tire width of the double-wheel mid-mounted motor device can be designed according to the load requirements of different uses.

[0007] The rear wheel suspension for three-wheel electric vehicles is very different from the front wheel suspension in design because there is no need to consider the steering problem. In order to facilitate the replacement of spare tires, the suspension method needs to refer to the rear wheel suspension of two-wheel electric vehicles. The method is: the parallel swing arm extending forward is actively connected to the connection point on the frame, the shock absorber installed actively at the rear end of the parallel swing arm is connected to the frame above, and an upper fixing frame with a semicircular cylindrical tile structure is provided in the middle. In addition to the brake caliper seat, the upper fixing frame is also provided with a lower fixing frame of the same cylindrical tile structure to fix the motor in a holding manner. In this way, the rear suspension of the three-wheel electric vehicle is completed by the parallel swing arm combined with the shock absorber and the coil spring and the frame. In order to facilitate the replacement of the spare tire close to one side of the car body (especially for vehicles equipped with a bottom shell), a horizontal axis and a vertical axis that allow the parallel arm to swing up and down and left and right can be set at the connection point in front of the parallel arm, and the shaft seats of the horizontal axis and the vertical axis can be manufactured together (castings can be used). In this way, the "dual-wheel mid-mounted motor device" installed on the rear wheel can vibrate up and down with the bumps of the road while the vehicle is driving. When the spare tire needs to be tilted outward, it can move left and right. The shock absorber with active connection at the end of the parallel arm can be used to slightly lift the body of the vehicle, and then the locking device set underneath can be taken out and lifted aside, and returned to its original position after the spare tire is replaced. (The above front and rear wheel running devices integrated with multiple technologies can be selected and applied on four-wheel, six-wheel and eight-wheel light electric vehicles.)

[0008] The frame of the three-wheeled electric vehicle draws on the frame of the two-wheeled electric vehicle to create a lightweight whole-circle design that combines the two into one, and can be manufactured with or without a bottom shell.

[0009] Power arrangement of three-wheeled electric vehicles: Install a motor with two functions like that of Tesla, which drives when the accelerator is depressed and generates electricity when the accelerator is lifted, and apply it to the three-wheel drive of three-wheeled electric vehicles. In principle, one motor is matched with a set of batteries. In this way, when the road conditions are good, it can run in single-wheel drive and two motors generate electricity. When the load is increased, it can run in two-wheel drive and one motor generates electricity. When climbing a steep slope, it can run in three-wheel drive for off-road, and when going downhill or coasting, all three motors can recover kinetic energy to generate electricity. If a single-effect motor is selected for installation, motors can be installed on the two rear wheels and a generator can be installed on the front wheel. When the vehicle is running in two-wheel drive or two motors drive the vehicle alternately, electricity can be continuously generated, and with the support of the electronic control, the batteries can be replenished alternately, thereby improving the endurance of the three-wheeled electric vehicle. In this way, with this "running device", plus the battery, electronic control and frame, a three-wheeled electric vehicle basically has the conditions for running. Next, the body can be manufactured according to different uses and special wheel and frame structures.

[0010] The three-wheeled light electric vehicle is a technical project that the inventor is very optimistic about. In theory, various types of passenger cars can be improved into three-wheeled vehicles with a smaller front and a larger rear according to the shape and style of the preferred sedan. The improved light three-wheeled electric vehicle, with a streamlined structure, lower wind resistance and frictional resistance, stronger load-bearing capacity, novel streamlined appearance, excellent handling and stability, is used for unmanned and intelligent urban bus applications where "it can come and go as you like", and will surely have good technical effects.

[0011] Taking the application of a two-wheel mid-mounted motor to four-wheel or multi-wheel vehicles as an example: Based on the two-wheel mid-mounted motor as the technical basis, to innovate four-wheel or multi-wheel electric vehicles, in the manufacture of the running device, it is necessary to refer to the two-wheel structure of large aircraft and the two-wheel design of suitcase with spring casters, integrate the technical hints of the present invention, and make a reasonable technical arrangement considering stability, durability and safety.

[0012] The frame that connects the wheels below and bears the body and also serves as the vehicle beam has most of its connections with the wheels along the waistline of the vehicle. Therefore, on the new electric vehicle, it plays a major role in hard protection and needs to be made of lightweight and high-strength metal materials with a load-bearing integral ring design. The two-wheel running device installed below can rotate 360 degrees around the steering axis in place, so that under manual and intelligent control, the vehicle can be translated, turned in place and move forward without distinction of head and tail. In order to facilitate the replacement of the spare tire and maintenance, and to facilitate the rotation of the wheels, when manufacturing the body, some internal space of the carriage needs to be occupied, and the bottom shell of the vehicle is recessed inward to leave enough room for the wheels to rotate. If the size of the frame is enlarged and combined with multi-wheel application, it can provide technical conditions for the manufacture of large buses and camping vehicles.

[0013] The vehicle body is manufactured in two parts: the bottom shell and the carriage. The bottom shell is made of high-quality nylon material through warm pressing as a whole according to the structural characteristics of the wheel and frame. The well-made bottom shell with a certain safety thickness is sleeved onto the frame with assembled wheels, and is bound to the frame in a bottom-up manner with high-quality nylon straps.

[0014] The "bread-shaped carriage" can be designed and manufactured in layers according to different climate conditions. In warm climate regions, the structural material is polypropylene and the inner core material is EVA. In cold climate regions, the structural material is polypropylene and the inner core material is EPS, a white soft foaming material with good heat insulation, good toughness, which is made into a whole through warm pressing. No matter which material is chosen, it must have a certain safety thickness to provide soft protection for the safe use of the vehicle. When necessary, EVA with better stiffness is used as the outer layer of the carriage, and the inner layer is made of EPS. The completed carriage is inserted into the vehicle bottom shell, and is supported from the inside by bamboo strips with good toughness, high strength and environmental friendliness, and is tightened from top to bottom with high-quality nylon straps outside and bound to the frame below. For a simple design, a rainproof and sun-proof replaceable carriage cover made of high-quality chemical fiber material is used for decoration. For a luxurious design, the carriage is surrounded or semi-surrounded with the material usually used to make bumpers for sedans. Before covering, an aluminum alloy guard plate is installed around the frame, and a protective bag filled with materials such as asbestos is hung outside the guard plate to mitigate the damage caused by collisions to the frame and the vehicle body. The protective bag made according to the vehicle shape is filled and installed at each key part and empty space of the vehicle, and supports the covering layer (mainly below the waistline) that is manufactured in parts and skillfully attached to the carriage. The interior decoration of the carriage can be done according to the sedan process, and for a luxurious design, materials such as fur that are more friendly to the human body can be selected for decoration. The front and rear windshield windows are preferably made of double-layer glass for heat preservation, and for the sake of reducing the weight of the vehicle, the sides are made of double-layer high-quality plastic glass with good transparency. For the pursuit of the vehicle's personalized design, several anti-roll exposed protective beams are added on the carriage, and the doors are designed to be installed on the metal protective beams to make up for the defect that the soft material used to make the carriage is not suitable for installing doors. For camping vehicles that are often used for traveling outdoors, a wire protective net that does not prevent the opening of the doors and windows can be sleeved outside the carriage to prevent wild animals from scratching and damaging the soft carriage and causing harm to the drivers and passengers. In addition, in order to enable the vehicle to float on the water surface and travel, the bottom shell is designed to be fully enclosed from the waistline downwards, and a pump-type propulsion is added when necessary. Doors are designed above the waistline, and the two side doors can be manually or automatically flipped up, and are tightened by magnetic attachment when they fall. A pedal step-in type is used to enter the carriage.

[0015] For the production of the car body of a sedan or an SUV, the part of the car body above the waistline, including the doors, can be designed and produced according to the shapes of various models in full accordance with the existing technology. After completion, it can be directly buckled onto the vehicle frame and attached to each part for installation. For such a car body produced in two parts, except for the shape of the wheels being different from the existing technology, the original external structure of the car is basically not changed.

[0016] The seat of the "bread - type light electric vehicle" suitable for camping trips requires a "multi - purpose and simplified" design to show a different design concept. First, stabilizing piles and tensioning devices should be made on the vehicle floor to stabilize the "seat". Secondly, referring to the shape of baby strollers and the operation mode of electric disability scooters for the elderly, a frame with a backrest is made. All four casters should be installed with double - wheel mid - mounted motors. The front two wheels used for power generation can be steered passively like the casters of a suitcase, and the rear two wheels used for driving can be steered forward by an electric controller to make the vehicle turn. For the made "seat - type tram", put the four casters on the four stabilizing piles on the vehicle floor, and connect them with the connection points at the cross - position of the four wheels under the seat through the tensioning device at the cross - position of the four stabilizing piles for tensioning and fixing. In this way, it is usually used as a seat and can be used as a means of transportation for shopping and sightseeing when needed. At least one such "seat - type tram" should be equipped in a bread - type camping electric vehicle. For the "auxiliary vehicle" designed as a non - powered two - wheel (single - wheel) and installed in the passenger seat, it can be carried by this "seat - type tram" when necessary. If needed, the two wheels of the auxiliary vehicle can be designed as double - wheels and also steered passively like the casters of a suitcase. When moving forward, it can continuously charge two groups of batteries for backup to improve the endurance of the seat - type tram. This new - type seat can replace the disabled vehicle under the existing technology and facilitate two people to travel together. According to the above method for enlargement and improvement, adding an electrically - operated reclining and lifting "egg - shell - type car body" that allows the driver to sit and drive and lie down to rest can manufacture a "super - micro light electric vehicle" with a vehicle mass of 100 catties and a lightweight design goal of carrying 150 catties.

[0017] In this way, through the above - mentioned series of improvement and innovation, a design scheme of a diversified, novel and practical new - type light electric vehicle can be completed.

[0018] Regarding the specific details of the "new - type light electric vehicle", in order to leave more room for innovation and imagination for relevant engineering and technical personnel in this field, and thus inspire the design of better technical components, those not limited in the claims are all technical hints, so no drawings are provided.

[0019] The present invention defines and names the Tiger Tally - type light electric vehicle. Any land - walking tool manufactured based on the technology of a two - wheel mid - mounted motor can be called a "Tiger Tally - type light electric vehicle". The two - wheel mid - mounted motor is defined and named. Any walking device for an electric vehicle designed and manufactured with the motor placed between two wheels can be called the "Tiger Tally two - wheel mid - mounted motor" technology.

[0020] As an indispensable component of the vehicle and the motor, the present invention has pre - designed and registered trademarks with the graphics of tigers and eagles as the logo for the "Tiger Tally - type light electric vehicle" and the "Tiger Tally two - wheel mid - mounted motor", and decides to use the graphics of the trademark as the technical logo of the present invention.

[0021] The prominent technical effects and significant progress of the present invention: Traditional vehicles are heavy in mass and load, with a heavy momentum and cause greater accident injuries. While the Tiger Tally - type light electric vehicle, because of its lighter vehicle body and relatively weaker power matching, can quickly shift to one side after a collision, resulting in less accident injury. Using the Tiger Tally two - wheel mid - mounted motor technology, the "Tiger Tally - type light electric vehicle" manufactured with lightweight design, through refined structural design, optimized power matching, lightweight body manufacturing, and lower energy consumption, improves the economy and practicality of the vehicle, and reduces the manufacturing and use costs of the vehicle. With a balanced gravity distribution and a lowered center of gravity setting, the stability and safety of the vehicle are improved. The use of a new material for the carriage not only provides soft protection for passengers, but also improves the heat insulation effect of the vehicle, enhancing the comfort of riding. The invention of the two - wheel mid - mounted motor enables pure electric vehicles to have the ability to continuously generate electricity during driving, thus improving the vehicle's endurance. The invention of the two - wheel mid - mounted motor opens up a new technical route for the development of vehicles towards being oil - free and a technical door for the lightweight manufacturing of pure electric vehicles. The Tiger Tally micro - mini electric vehicle, which occupies a relatively small road area, if it can form a scale advantage in market applications, will surely play an important role in alleviating urban traffic pressure. The invention of the Tiger Tally - type light electric vehicle provides a new technical category for diverse choices of transportation means.
