Description

Technical Field

[0001] This invention belongs to the field of electric bicycle technology and relates to an intelligent electric bicycle that can be conveniently charged and has turn signals. Background Technology

[0002] Electric vehicles are electric-powered vehicles that conform to the national trend of energy conservation and environmental protection. They greatly facilitate short-distance transportation and, most importantly, play a vital role in the national economy by saving and protecting energy and the environment.

[0003] Two-wheeled electric vehicles on the market mainly consist of the frame, wheels, a bogie (the support for the handlebars), a battery, and a motor. To facilitate use, electric vehicles have undergone improvements in many aspects. The applicant's research has revealed that existing electric vehicles suffer from issues with charging convenience.

[0004] There are generally two types of electric vehicle charging methods on the market: one is where the battery is fixed inside the vehicle body, requiring the electric vehicle to be moved to a charging station for charging via a charging cable. This method is generally used for larger electric vehicles, with the advantage of a larger battery and longer range. The disadvantage is that the vehicle must be moved to a fixed charging station location for each charge, and charging cannot be done if the parking location is not suitable. The other type is where the battery is detachable from the vehicle body, generally used for smaller electric vehicles. The advantage is that the detachable battery offers more charging options, and the battery can be removed for charging when parking is inconvenient. The disadvantage is that because the battery itself is heavy, it is generally only used in smaller electric vehicles, resulting in a disadvantage in range.

[0005] With the development of transportation and the promotion and popularization of new energy, there are more and more electric vehicles in people's lives. However, the number of charging stations in residential areas is limited, which can easily lead to situations where electric vehicles cannot be charged as needed. Therefore, it is increasingly necessary to design electric vehicle batteries to be detachable. However, the size of detachable batteries cannot be too large to avoid difficulties in transportation. Therefore, the optimization and improvement of battery design is necessary. Summary of the Invention

[0006] The purpose of this invention is to address the problem of inadequate charging methods for existing electric vehicles by proposing a smart electric bicycle that can be conveniently charged and has turn signals.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A smart electric bicycle with convenient charging and turn signals includes a frame, wheels, a bogie, turn signals, a headlight, a motor, a gearbox, and a power supply component. The power supply component comprises a bracket fixedly mounted on the frame and made of insulating material; two battery compartments fixedly mounted side-by-side on the bracket and having a vertical limiting structure; two battery packs detachably mounted in the two battery compartments from above; and a conductive hard wire fixedly laid on the bracket in a vertical plane. The bottom of the battery packs has positive and negative contacts. The motor is mounted on the line containing the hard wires. The upper part of the hard wires has two cut-off points, and both ends of the cut-off points have conductive connecting rods. After the two battery packs are placed in the battery compartments, the positive and negative contacts of the battery packs connect with the connecting rods.

[0009] In the aforementioned intelligent electric bicycle with convenient charging and turn signals, a first frame with a first through hole is fixedly mounted on the bracket. An insulating upright is movably mounted within the first through hole. A retaining ring is fixedly mounted on the outer ring of the retaining upright. The retaining ring is located above the first frame, and a first spring is provided between the retaining ring and the first frame. An insulating pressing body is provided at the upper end of the retaining upright. The pressing body is located below the battery pack and can be pressed down by the battery pack. A conductive crossbar with conductivity is horizontally mounted on the retaining upright. The conductive crossbar is aligned with the cut-off point. When there is no battery pack above the pressing body, the first spring springs up, causing the conductive crossbar to connect with the cut-off point. Both the first frame and the retaining upright have two correspondingly mounted parts, which are also correspondingly mounted at the two cut-off points.

[0010] In the aforementioned intelligent electric bicycle that is conveniently charged and equipped with turn signals, the docking guide rod is vertically arranged, and a second frame with a second through hole is fixedly mounted on the bracket. The docking guide rod is movably mounted in the second through hole, and a guide rod retaining ring is fixedly mounted on the outer ring of the docking guide rod. The guide rod retaining ring is located above the second frame, and a second spring is provided between the guide rod retaining ring and the second frame. There are four second frames, each corresponding to one of the four docking guide rods.

[0011] In the aforementioned intelligent electric bicycle with convenient charging and turn signals, the lower part of the circuit has a disconnection section. A third frame with a third through hole is fixed on the bracket. The third frame is located below the disconnection section. An insulating vertical rod is movably mounted in the third through hole. A vertical rod retaining ring is fixed around the outer ring of the vertical rod. The retaining ring is located above the third frame, and a third spring is provided between the retaining ring and the third frame bracket. A switching component is horizontally mounted on the vertical rod. The switching component is formed by the upper part of the resistor and the lower part of the conductive strip. The conductive strip has no resistance. An extension frame is also vertically fixed on the vertical rod. Two compensation compression bodies are forked at the upper end of the extension frame. The two compensation compression bodies are located below the two battery packs respectively. When there is no battery pack above either of the two compensation compression bodies or only one compensation compression body is under the pressure of the battery pack, the conductive strip connects with the disconnection section under the action of the third spring. When both compensation compression bodies are under the pressure of the battery pack, the resistor connects with the disconnection section.

[0012] In the aforementioned intelligent electric bicycle that is conveniently rechargeable and equipped with turn signals, the resistive element is a storage battery, which is used to provide power to the electric bicycle's other electrical components besides the motor.

[0013] In the aforementioned intelligent electric bicycle that is conveniently rechargeable and equipped with turn signals, the bracket is provided with multiple limiting structures. The circumference of the connecting guide rod, the retracting upright rod, and the compensating vertical rod are all limited by the limiting structures, forming a movement mode that can only move up and down but cannot rotate.

[0014] In the aforementioned intelligent electric bicycle that is conveniently rechargeable and equipped with turn signals, a carrying handle is provided above the battery pack.

[0015] In the aforementioned intelligent electric bicycle that is conveniently rechargeable and equipped with turn signals, the battery pack uses lithium batteries.

[0016] Compared with existing technologies, this smart electric bicycle offers greater charging options by splitting the battery into two or more individually removable sub-batteries, and ensuring that the circuit can function normally even with any one of the batteries present.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] This smart electric bicycle, which can be easily charged and has turn signals, includes a frame, wheels, bogie, turn signals, headlights, motor 19 (motor 19 is an adjustable power motor 19, and the speed is adjusted by rotating the handle, which is the design of all electric bicycles on the market), gearbox, and power supply components.

[0026] The above is the basic layout design of all electric vehicles on the market.

[0027] like Figures 1-6 As shown, the power supply component includes a bracket fixedly mounted on the vehicle body and made of insulating material, two battery compartments fixedly mounted side by side on the bracket and having a vertical limiting structure, two battery packs 1 detachably mounted in the two battery compartments from above, and a conductive hard wire 2 fixedly laid on the bracket in a vertical plane. The bottom of the battery pack 1 is provided with positive and negative contacts 3. The motor 19 is mounted on the line where the hard wire 2 is located. The upper part of the hard wire 2 is provided with two cut-off points. Both ends of the cut-off points are provided with conductive connecting rods 4. After the two battery packs 1 are placed in the battery compartment, the positive and negative contacts 3 of the battery pack 1 are connected with the connecting rods 4.

[0028] The above is the basic design of the present invention. The battery pack 1 is split into two (the present invention is designed to be two, which is a more reasonable case. Although it can also be split into three, four or more through the design concept of the present invention, the energy storage capacity of a single battery pack 1 will be limited if it is set too many. Therefore, using two is the most reasonable case). When people need to charge, they only need to take out one of the battery packs 1 to charge. In this way, the difficulty of lifting the battery pack 1 is greatly reduced after the heavy battery is split into two.

[0029] Under the above basic design, both batteries must be placed in the battery compartment for the circuit containing hard wire 2 to be completed. Therefore, if people forget to remove the batteries, or if only one battery pack 1 is available, the circuit cannot be used. To avoid this situation, this design also provides the following technical solutions to optimize the basic design.

[0030] like Figures 1-4 As shown, a first frame 5 with a first through hole is fixed on the bracket. A retractable upright 6 made of insulating material is movably installed in the first through hole. A retaining ring is fixed on the outer ring of the retractable upright 6. The retaining ring is located above the first frame 5, and a first spring 7 is provided between the retaining ring and the first frame 5. A retractable pressing body 8 made of insulating material is provided at the upper end of the retractable upright 6. The retractable pressing body 8 is located below the battery pack 1 and can be pressed down by the battery pack 1. A conductive crossbar 9 with conductive capability is horizontally mounted on the retractable upright 6. The conductive crossbar 9 is aligned with the cut-off point. When there is no battery pack 1 above the retractable pressing body 8, the first spring 7 springs up to connect the conductive crossbar 9 with the cut-off point. The first frame 5 and the retractable upright 6 each have two correspondingly arranged parts, which are also correspondingly arranged at the two cut-off points.

[0031] The docking guide rod 4 is vertically arranged, and a second frame 10 with a second through hole is fixed on the bracket. The docking guide rod 4 is movably arranged in the second through hole. A guide rod retaining ring is fixedly arranged on the outer ring of the docking guide rod 4. The guide rod retaining ring is located above the second frame 10, and a second spring 11 is provided between the guide rod retaining ring and the second frame 10. There are four second frames 10, each corresponding to one of the four docking guide rods 4.

[0032] from Figure 1 , Figure 3 , Figure 5As can be seen, if battery pack 1 is placed in the battery compartment above the cut-off point, the weight of battery pack 1 will cause the bottom of battery pack 1 to press down the retracting extrusion body 8, resulting in the entire retracting upright 6 moving downwards. The conductive crossbar 9 will also move downwards accordingly and disengage from the hard wire 2. However, because the positive and negative contacts 3 at the bottom of battery pack 1 are connected to the connecting guide 4, battery pack 1 is located on this line. If no battery is placed in the battery compartment, the retracting upright 6 is not under pressure, and the first spring 7 will cause the retracting upright 6 to be in an upward-springing state. At this time, the conductive crossbar 9 is connected to the cut-off point, so the conductive crossbar 9 is located on this line. In other words, as long as one battery pack 1 is on the line, it doesn't matter whether another battery is placed there or not, because even without a battery, a circuit will be formed under the action of the conductive crossbar 9.

[0033] Based on the above design premise, there are two scenarios: one is that there is only one battery pack 1 in the circuit, and the other is that two battery packs 1 are connected in series in the circuit. If the voltage provided by each battery pack 1 is U, then the voltages in the circuit in the two scenarios will be U and 2U respectively. However, according to the new national standard for electric vehicles issued in 2022, the maximum speed of electric vehicles shall not exceed 25km / h. Therefore, it is necessary to control the total maximum power of motor 19. If the design standard is based on the amount of 1U of one battery pack (that is, just enough to provide the maximum power standard of 25km / h), then when both batteries are in the circuit, the maximum power provided by motor 19 will inevitably exceed the standard. In this case, further design is required.

[0034] like Figures 1-6 As shown, the lower part of the line has a break section. A third frame 12 with a third through hole is fixed on the bracket. The third frame 12 is located below the break section. A compensating vertical rod 13 made of insulating material is movably mounted in the third through hole. A vertical rod retaining ring is fixed around the outer ring of the compensating vertical rod 13. The vertical rod retaining ring is located above the third frame 12, and a third spring 14 is provided between the vertical rod retaining ring and the bracket of the third frame 12. A switching assembly is horizontally mounted on the compensating vertical rod 13. The switching assembly is formed by the upper part of the resistor 15 and the lower part of the conductive horizontal bar 16. The conductive horizontal bar 16 has no resistance. (In an ideal state, there is no resistance, and it acts as a wire). An extension frame 17 is also longitudinally fixed on the compensation vertical rod 13. Two compensation compression bodies 18 are located at the fork of the upper end of the extension frame 17. The two compensation compression bodies 18 are located below the two battery packs 1 respectively. When there is no battery pack 1 above either of the two compensation compression bodies 18 or only one compensation compression body 18 is under the pressure of the battery pack 1, the conductive horizontal bar 16 is connected to the disconnection part under the action of the third spring 14. When both compensation compression bodies 18 are under the pressure of the battery pack 1, the resistor 15 is connected to the disconnection part.

[0035] The conductive strip 16 has a relatively large vertical width, so even when it descends only slightly, it still aligns with the break in the section. Therefore, when Figure 1 and Figure 2 Without any battery pack 1, the third spring 14 is in its highest position. At this time, the lowest end of the lower half of the conductive crossbar 16 is connected to the disconnected part. Figure 3 and Figure 4 When there is only one battery pack 1, due to insufficient pressure, the third spring 14, although compressed, is not fully depressed. At this time, the conductive bar 16 moves slightly downward but remains connected to the disconnected part. Figure 5 and Figure 6 During the cleaning process with both battery packs 1 in place, the third spring 14 is compressed sufficiently due to the sufficient pressure. At this point, the conductive crossbar 16 has also detached from the disconnected part and is replaced by a resistor 15 with a certain resistance value. Through the voltage division effect of the resistor 15, the motor 19 is additionally deducted from the voltage when there are two battery packs 1, so that the power obtained by the motor 19 can meet the national standards even when there are two batteries.

[0036] Of course, voltage division through resistor 15 would result in energy waste, which is not in line with the rational use of energy. Therefore, the energy that is divided should not be wasted. Thus, the following design was carried out.

[0037] Resistor 15 is a storage battery, which is used to provide power to other electrical components of the electric vehicle other than motor 19 (such as headlights, turn signals, USB charging ports).

[0038] Resistor 15 itself is a storage battery with energy storage function. This battery is used to provide power to other parts of the electric vehicle that need power. Optional integrated functions such as headlights, turn signals, brake lights, digital displays, USB charging ports, and heating pads can all be powered by the storage battery.

[0039] The support frame is equipped with multiple limiting structures. The circumference of the connecting guide rod 4, the retracting upright rod 6, and the compensating vertical rod 13 are all limited by the limiting structures, resulting in a movement that can only move up and down but not rotate. This design is mainly to prevent the conductive crossbar 9, the resistor 15, and the conductive crossbar 16 from swaying.

[0040] A handle is provided on the top of battery pack 1, and battery pack 1 uses lithium batteries.

[0041] Turn signals are divided into left turn signals and right turn signals. The switch for the left turn signal is connected to the handle of the front brake system, and the switch for the right turn signal is connected to the handle of the rear brake system.
