Description

Technical Field

[0001] The utility model relates to the technical field of parking systems, in particular to an automatic parking system in a charging state. Background Art

[0002] The sightseeing buses operating in scenic areas are generally electrically driven, so they need to be charged according to demand. During the charging process, if the ignition lock is forgotten to be turned off, it is easy for the vehicle to rush out of the charging area and damage the charging equipment due to accidentally stepping on the accelerator pedal. Or if there is no dedicated charging area, the driver does not know whether the vehicle is in a charging state and directly starts and drives it, which eventually causes damage to the charging equipment. Utility Model Content

[0003] In order to solve the problem that the electric sightseeing vehicle can be driven normally in the charging state, the utility model provides an automatic parking system in the charging state.

[0004] The technical solution of this utility model is as follows:

[0005] A charging state automatic parking system, comprising a motor and a motor controller connected to and controlling the motor, wherein the motor controller is connected to a power supply battery and an accelerator pedal, and a resistor controlled by an electric door lock is arranged between the motor controller and the power supply battery, and further comprising a current transformer sleeved on a charging line of the power supply battery, wherein an output end of the current transformer is connected to an input end of a relay, and the relay is a normally closed relay and can be switched to an open state after the current transformer generates current;

[0006] The relay is arranged in the control loop of the motor controller and can cut off the current loop where the accelerator pedal or the electric door lock is located.

[0007] The current circuit is controlled by a relay, thereby achieving the effect of preventing the accelerator pedal from functioning normally. The above operation does not require manual setting, but is performed automatically when the vehicle is charging.

[0008] In order to facilitate the selection of the state according to the needs, the relay can choose to cut off the current loop where the accelerator pedal or the electric door lock is located. It can make the vehicle unable to move or unable to power on, and the purpose can be selected according to the needs.

[0009] In order to avoid duplication of functions, the relay cannot cut off the current circuits of the accelerator pedal and the electric door lock at the same time.

[0010] As a preferred solution, the relay is arranged between the electric door lock and the resistor. When the relay is in an open state, the electric door lock cannot form a complete circuit even if it is opened, thereby preventing the vehicle from starting.

[0011] In order to facilitate the staff to switch the state according to the needs, two relays are set, and they are respectively set between the motor controller and the accelerator pedal and between the electric door lock and the resistor, and a double-control switch is set between the two relays. In the same period, only one relay can work. According to the needs, you can choose whether to power off the whole vehicle or only the accelerator pedal in the charging state.

[0012] As another preferred solution for state switching, the relay is provided between the motor controller and the accelerator pedal and between the electric door lock and the resistor, and the relay input is also connected to the output of the central control display screen, and the input of the central control display screen is connected to the power supply battery. Different from the above-mentioned state switching method through the double control switch, the present device integrates it in the central control display screen, switches the state by touch, and can also realize the selection of whether to power off the whole vehicle in the charging state or only the accelerator pedal.

[0013] In order to limit the rotation of the motor, the motor is also provided with an electromagnetic lock, and the electromagnetic lock is connected with an unlocking switch.

[0014] For safety reasons, an emergency stop switch is provided between the power supply battery and the resistor.

[0015] The specific structure of the motor controller is that the motor controller includes a processor, a Bluetooth communication module and an external serial port terminal, and the processor adopts an STM32F303RBT6 chip.

[0016] The beneficial effects of the utility model are as follows: the utility model is a charging state automatic parking system, which adds a current transformer and a relay on the basis of the existing electric sightseeing car, and can keep the relay in a normally closed state when not charging so as not to affect the normal driving of the vehicle. When charging, the state of the relay is changed by the current transformer to enter an open state, so that the control circuit of the motor controller cannot be closed, which can ensure that normal driving cannot be carried out during the charging process, and can avoid the phenomenon of damage to the charging equipment due to accidental driving of the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] By reading the detailed description of the preferred embodiment below, the scheme and advantages of the present application will become clear to those skilled in the art. The accompanying drawings are only used to illustrate the preferred embodiment and are not considered to be limiting of the present invention.

[0018] In the attached picture:

[0019] Figure 1 This is a schematic diagram of the structure of Embodiment 1 of the present utility model;

[0020] Figure 2 This is a schematic diagram of the structure of Embodiment 2 of the present utility model;

[0021] The components represented by the reference numerals in the figure are: DETAILED DESCRIPTION

[0022] like Figure 1 The charging state automatic parking system shown in the figure includes a motor, the motor is used to drive the vehicle forward and backward, and in order to control the motor speed and adjust the vehicle speed, a motor controller connected to and controlling the motor is also required, the motor controller can control the motor to achieve vehicle travel control, and then the motor controller is connected to a power supply battery and an accelerator pedal, wherein the power supply battery is used to supply power to the car after leaving the power supply to ensure that the vehicle can travel a certain distance, and after the accelerator pedal is connected to the motor controller, the moving speed of the vehicle can be adjusted, and then, in order to facilitate the vehicle to shut down and power off in an idle state, as shown in FIG. Figure 1 As shown, a resistor controlled by an electric door lock is arranged between the motor controller and the power supply battery, and for safety reasons, an emergency stop switch is arranged between the power supply battery and the resistor. The emergency stop switch is a car fuse that can achieve overload protection, and the above-mentioned resistor and related settings have been disclosed in the patent documents previously applied for by the company, so this design will not be described in detail.

[0023] The key point of the utility model is that the device also includes a current transformer that is sleeved on the charging line of the power supply battery. First, the charging line of the power supply battery needs to be connected to the charger and charged. After the current transformer is sleeved on its outer side, if charging is carried out, there will be current in the charging line. Correspondingly, the current transformer can generate current, and different from the large current used for charging, the current transformer can select an adaptive transformation ratio to obtain a smaller current. Afterwards, the output end of the current transformer is connected to the input end of the relay. The relay is a normally closed relay and can be switched to an open state after the current transformer generates current. The presence of the normally closed relay in the circuit will not affect the current loop. Once it is switched to an open state, it can achieve the same effect as the electric door lock, realizing power off at some positions, and the switching of its state does not require manual operation, but is automatic. In other words, the state of the relay can be changed by only charging the power supply battery. Thereby solving the problems existing in the background technology

[0024] To this end, the relay is set in the control circuit of the motor controller and can cut off the current circuit where the accelerator pedal or the electric door lock is located. Cutting off the accelerator pedal can avoid acceleration caused by accidentally stepping on the accelerator pedal, which can also prevent the vehicle from moving during the charging process. Cutting off the current circuit where the electric door lock is located will not only make the accelerator pedal inoperable, but also other functions controlled by the electric door lock will be inoperable. Through the above settings, the user can select the setting position and realize different functions.

[0025] The above structure can be used to control the current circuit through the relay, thereby achieving the effect of preventing the accelerator pedal from functioning normally, and the above operation does not require manual setting, but is automatically performed when the vehicle is charging.

[0026] Afterwards, based on the above structure, in order to facilitate the selection of the state according to the needs, the relay can choose to cut off the current loop where the accelerator pedal or the electric door lock is located. It can make the vehicle unable to move or unable to power on, and the purpose can be selected according to the needs.

[0027] What needs to be noted in the above structure is that in order to avoid duplication of functions, the relay cannot cut off the current loops of the accelerator pedal and the electric door lock at the same time during the same period of time.

[0028] In addition to the above structure, in order to limit the rotation of the motor, the motor is also provided with an electromagnetic lock, and the electromagnetic lock is connected to an unlocking switch.

[0029] The specific structure of the above-mentioned motor controller is the same as the structure in the company's previous patent application. The motor controller includes a processor, a Bluetooth communication module and an external serial port terminal, and the processor adopts the STM32F303RBT6 chip. The specific principle will not be repeated here.

[0030] As a preferred embodiment, Figure 1 As shown, in order to facilitate the staff to switch the state according to the needs, two relays are set, and they are respectively set between the motor controller and the accelerator pedal and between the electric door lock and the resistor, and a double-control switch is set between the two relays. In the same period, only one relay can work. According to the needs, you can choose whether to power off the whole vehicle or only the accelerator pedal in the charging state. The double-control switch can be set at the main control platform of the vehicle and can be switched manually by the staff.

[0031] As another preferred embodiment, Figure 2 As shown, as another preferred solution for state switching, the relay is simultaneously arranged between the motor controller and the accelerator pedal and between the electric door lock and the resistor, and the relay input is also connected to the output of the central control display screen, and the input of the central control display screen is connected to the power supply battery. Different from the above-mentioned method of switching states through a dual-control switch, the present device integrates it in the central control display screen, and switches states by touch. It can also realize the selection of whether to power off the entire vehicle and only the accelerator pedal in the charging state. This method is suitable for the method where an additional dual-control switch cannot be set, but with the help of the original central control display screen, the switching function is integrated with it, which is more convenient for control, but the corresponding changes are relatively large, and the two methods need to be freely selected according to needs.
