Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric vehicles, in particular to a dual battery system of an electric bicycle. Background Art
[0002] An electric bicycle is a vehicle that uses electricity to drive. Compared with traditional bicycles, electric bicycles are more convenient to drive. You can easily travel longer distances by pedaling or turning the electric power button, reducing human labor. Electric bicycles have relatively safe speeds and load-carrying capacity, which can meet people's needs for short-distance travel. Electric bicycles are environmentally friendly and do not produce exhaust emissions, reducing pollution to the environment. Electric bicycles also save people time and money, avoiding traffic congestion and parking fees.
[0003] Electric bicycles also have many problems and shortcomings. The battery life and durability of electric bicycles are limited. Once the battery is exhausted, it needs to be recharged before it can be used again, which is inconvenient when traveling long distances. Due to land shortages in many cities, there are few places to safely park and charge electric bicycles. In addition, some communities in cities have begun to ban electric bicycles from entering the community for safety reasons, so how to charge and park electric bicycles has become a problem.
[0004] The charging problem can be solved by using a battery replacement solution, but the problem of not being able to drive electric bicycles into residential areas for parking needs to be improved. Summary of the invention
[0005] The utility model aims at the defects of the prior art that electric bicycles are inconvenient to charge and difficult to drive into residential areas for parking, and provides a new dual-battery system for electric bicycles.
[0006] In order to solve the above technical problems, the utility model is implemented through the following technical solutions:
[0007] A dual battery system for an electric bicycle includes a vehicle body, a main battery, and a secondary battery. The vehicle body is provided with a pedal area. The main battery is located in the pedal area and is detachably connected to the vehicle body. The secondary battery is located in the pedal area and is fixedly connected to the vehicle body.
[0008] The main battery is used for daily long-distance travel on electric bicycles. The detachable connection realizes the battery replacement function, eliminating the trouble of finding a charging station. The auxiliary battery is used to provide electric assistance for riding the electric bicycle after the main battery is removed, making it easier for users. The auxiliary battery is a small battery that meets civil aviation safety requirements. It is safe and reliable and can be taken on board. After the main battery is removed, it can be parked in a residential area where electric vehicles are prohibited from entering.
[0009] The utility model realizes a dual battery system for electric bicycles through the above design, so that the problem of difficulty in charging the electric bicycle can be solved by battery replacement. After the main battery is removed and placed in the battery replacement cabinet, the parking problem in a community where electric vehicles are prohibited can be solved without taking out a new main battery first. The auxiliary battery can then be used for electric assistance to ensure fast and convenient travel between the battery replacement cabinet and the community.
[0010] Preferably, in the dual battery system of the electric bicycle described above, the main battery is located in the middle of the pedal area.
[0011] The main battery is located in the middle of the pedal area, which is convenient for disassembly and assembly, improving the convenience of battery replacement and improving space utilization.
[0012] Preferably, in the dual battery system of the electric bicycle described above, the secondary battery is located in front of the pedal area.
[0013] The secondary battery is located in front of the pedal area, which improves space utilization and avoids affecting the removal and installation of the main battery.
[0014] Preferably, in the dual battery system of the electric bicycle described above, the secondary battery is fixedly connected to the vehicle body by means of buckles or screws.
[0015] The auxiliary battery is completely fixed to the vehicle body through buckles or screws, and cannot be easily disassembled, thereby improving structural stability.
[0016] Preferably, in the dual battery system of the electric bicycle described above, a pedal assembly is provided behind the pedal area, and the pedal assembly cooperates with the auxiliary battery.
[0017] The pedal assembly is used for users to ride, and the auxiliary battery provides electric assistance, which improves convenience, applicability and usage experience.
[0018] Preferably, in the dual battery system of the electric bicycle described above, the main battery is electrically connected to the auxiliary battery.
[0019] The secondary battery can be recharged by the main battery, but the main battery cannot be recharged by the secondary battery. After the main battery is connected, the secondary battery stops providing electric assistance. The above design increases the recharge method of the secondary battery, improving the battery life and user experience of the secondary battery.
[0020] Preferably, in the dual battery system of the electric bicycle described above, a solar panel assembly is provided on the rear side of the vehicle body, and the solar panel assembly is electrically connected to the auxiliary battery.
[0021] The solar panel assembly is used to replenish the auxiliary battery to prevent the auxiliary battery from being damaged due to power loss when the electric bicycle is left unused for a long time. BRIEF DESCRIPTION OF THE DRAWINGS
[0022] Figure 1 It is a cross-sectional schematic diagram of the utility model;
[0023] Figure 2 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0024] The following is combined with Figure 1-2 The present invention is further described in detail with the following specific embodiments, but they are not intended to limit the present invention:
[0025] Example 1
[0026] A dual battery system for an electric bicycle includes a vehicle body 1, a main battery 2, and a secondary battery 3. The vehicle body 1 is provided with a pedal area 4. The main battery 2 is located in the pedal area 4 and is detachably connected to the vehicle body 1. The secondary battery 3 is located in the pedal area 4 and is fixedly connected to the vehicle body 1.

[0032] Preferably, a solar panel assembly 6 is provided on the rear side of the vehicle body 1 , and the solar panel assembly 6 is electrically connected to the auxiliary battery 3 .
[0033] The electric bicycle with dual battery system does not need to be equipped with a charging port, and the energy is fully replenished by battery replacement, which greatly reduces the charging time and avoids various charging safety hazards, such as charging with flying wires and taking the battery home to charge. In daily use, the main battery 2 is inserted, and the main battery 2 provides energy for electric travel and replenishes the auxiliary battery 3. When the battery is out of power, it can be replaced.
[0034] A foot pedal is provided in the foot pedal area 4. When the battery needs to be replaced, the foot pedal is opened with a key, the main battery 2 is removed, and placed in the battery replacement cabinet. The new main battery 2 in the battery replacement cabinet is placed in the position of the original main battery 2, and then the discharge socket is connected.
[0035] When you need to park in a residential area where electric vehicles are prohibited from entering, you only need to remove the main battery 2 and put it into the battery exchange cabinet, and then use the auxiliary battery 3 and the pedal assembly 5 to ride back to the residential area for parking. The auxiliary battery 3 is a battery with a rated energy of less than 160Wh, which meets civil aviation safety requirements.
[0036] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made within the scope of the patent application for the present invention should fall within the scope of the present invention.
