Description

Technical Field

[0001] The invention belongs to the technical field of shared vehicle operation and maintenance, and specifically relates to a method for opening a seat bucket of a low-power shared vehicle. Background Art

[0002] During the operation of two-wheeled electric vehicles in the market, the battery is often locked in the seat barrel due to undervoltage. At this time, the operation and maintenance personnel cannot open the seat barrel lock when replacing the battery. Of course, mechanical keys can be used, but they are used in too many vehicles, and the keys and locks correspond one by one, resulting in too many keys and difficult to distinguish, which brings great challenges to the maintenance time and workload of the operation and maintenance personnel. In addition, the use of mechanical structures can be operated by everyone, and there is a risk of battery loss. Therefore, most of the existing shared two-wheeled electric vehicles use electric control locks to control the seat barrel. However, when the operation and maintenance personnel are doing maintenance, it is easy for the battery to be locked in the seat barrel due to undervoltage.

[0003] For example, patent application No. 202022843829.1 proposes a shell and a two-wheeled vehicle, which proposes that with the rapid development of social economy and the continuous improvement of scientific and technological levels, people's requirements for energy conservation, emission reduction and environmental improvement are getting higher and higher, and electric vehicles are increasingly considered to be the direction of future automobile development. At present, batteries are generally used to power electric vehicles. The batteries are generally placed in the battery compartment and are detachably connected to the battery compartment. When charging is required, the battery only needs to be removed for charging, and then placed in the battery compartment after charging. To prevent the battery from being stolen, electronic locks are set on the battery compartment and the compartment cover. When the battery power is low or out of power, the central control controls the electronic lock to open, so that the operation and maintenance personnel can take out the battery for replacement. When the backup battery and the power supply battery in the central control are out of power at the same time, the central control cannot communicate with the electronic lock to control the electronic lock to open, so that the operation and maintenance personnel cannot replace the battery, affecting the normal use of the electric vehicle;

[0004] The specific means adopted include a shell, a seat bucket with a central control module, a charging terminal, a seat bucket cover, a seat bucket lock, a taillight, a motor controller, a battery, a rear wheel, a front wheel frame and a front wheel, the seat bucket is located between the two side covers and the rear wheel cover, the charging terminal is fixed in the connecting hole, the inner end of the charging terminal is electrically connected to the central control module through a cable, the outer end of the charging terminal extends from the rear wheel cover, one side of the seat bucket cover is rotatably connected to the seat bucket, the seat bucket lock is detachably connected between the seat bucket cover and the seat bucket, the seat bucket lock is communicatively connected to the central control module, the charging terminal is a DC charging terminal, the taillight is connected between the two side covers and located above the rear wheel cover, and the taillight is electrically connected to the central control module. The motor controller is fixedly arranged between the seat bucket and the rear wheel cover, the motor controller is electrically connected to the central control module, the battery is arranged in the seat bucket, the battery is located above the central control module and is electrically connected to the central control module, a connecting plate is extended outwardly from the top of the seat bucket in a circumferential direction, the connecting plate is fixedly connected to the tops of the two side covers, the seat bucket includes a buffer, a limiting rib and a wire outlet, the buffer and the limiting rib are located on the inner side wall of the seat bucket and the buffer is located above the limiting rib, the wire outlet is located at the bottom of the seat bucket, the rear wheel is connected to the side cover, the rear wheel is located below the rear wheel, the front wheel frame is connected to the side cover and extends to the front of the rear wheel, and the front wheel is connected to the front wheel frame.

[0005] In this patent, the charging bill is fixed in the connecting hole of the rear wheel cover, so that the position of the charging terminal is concealed, which can prevent malicious damage to the charging terminal and facilitate maintenance personnel to remove the battery when the battery is out of power. However, this method is still very cumbersome and not easy to maintain shared vehicles. Summary of the invention
