detailed description

Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

As shown in the figure, the present invention provides an electric vehicle charging pile system, which includes a charging pile body, a clamping mechanism 8 is provided at the bottom of the charging pile body, and the clamping mechanism includes a U-shaped fixing part. Two clamping parts are correspondingly arranged on both sides of the inner wall of the fixing part, and the clamping parts are connected with the transmission mechanism. Sensor 5, the pressure sensor can be used to detect whether there is a car in the clamping mechanism, and can also detect the change of pressure to avoid excessive clamping and damage the tire. Secondly, it can also obtain the current air pressure of the tire according to the comparison of the detected data. And it can remind the user to inflate the tires. The charging pile is provided with a control module 1, and the control module includes:

The receiving module 11 is connected to the pressure sensor 5 for real-time detection of the pressure at the clamping part;

The processing module 12 is connected with the receiving module 11, receives the pressure data and performs charging control according to the detected pressure data. When it is detected that an electric vehicle enters the clamping mechanism, the tire of the electric vehicle will press the pressure sensor. And only when the pressure data detects the data, the clamping mechanism will clamp it and start the normal charging mode;

The operation module 14 is used for human-computer interaction to perform charging, unlocking and payment operations.

The payment mode selection terminal 7 is set on the charging pile body. With the popularization of mobile phones, users can make payment selections through apps such as Alipay and WeChat. At the same time, after the first payment is completed, the charging user network account is automatically created. For example: the WeChat public account, which provides users with real-time feedback on the charging situation, and promptly notifies the user of the situation of picking up the car. At the same time, the location signal of idle charging piles can be broadcast to prevent users from searching for idle charging piles in the park. At the same time, a charging appointment can be made.

Two charging terminals are arranged in the charging pile body, one is a normal charging terminal 4, and the other is a fast charging terminal 3, and the length of the charging line of the normal charging terminal is the same as the charging position of the car in the clamping mechanism. Adaptation, the charging line of the fast charging end is longer than the charging line of the normal charging end. On the one hand, it is used to provide users with two services, and on the other hand, it solves the waste of one charger for one car.

The fast charging terminal is indicated by a different color from the normal charging interface, providing assistance to users who are in urgent need of charging. And the fast charging cable is much longer than the normal charging cable, so it can be charged behind the electric vehicle that is being charged normally.

The normal charging line is divided into two types of interfaces (60V and 48V), which protect the battery of the electric vehicle. The normal charging line is only enough for the distance of the charging interface of the electric vehicle correctly placed in the clamping mechanism to ensure that the fixed electric vehicle The situation of one vehicle charging one vehicle avoids the chaos of power supply stations snatching charging piles.

Both the normal charging end and the fast charging end are equipped with an automatic charging line recovery mechanism 2, and the automatic recovery mechanism includes two support seats 21 fixedly arranged on the inner wall of the charging pile body, and a winding is hinged between the two support seats. Wheel 22, the charging cable is wound on the winding wheel, and a spring (omitted) providing torsion is arranged between the winding wheel and the support seat. Using the torsion provided by the spring, when the charging cable is pulled out, the winding wheel puts a pressure on the spring, and when the charging cable is fully pulled out, a gear can be set to block the winding wheel to prevent it from automatically returning to the line, while After the charging is over, use the button or other structure to make the winding wheel out of this gear, and the charging cable can be automatically retracted by the torsion of the spring, which avoids the problem that the charging cable is always exposed and easy to be damaged in the past. After the line, the rewinding wheel is stuck in another gear, and this gear is electronically controlled by the control module. If and only when someone swipes the card or pays the charging fee, the gear can be released and the charging line can be pulled out to avoid malicious people. Damage the charging cable.

A charging line inlet is provided on the charging pile body, and an infrared sensor is arranged above the inlet, and the charger connected to the charging line covers the infrared sensor after the charging line is completely recovered. It is activated after charging, that is, after the user finishes charging, the charging cable is not recovered, and the infrared sensor does not detect that the charger is placed in a fixed position, and it will alarm to remind the user to recover the charging cable, and when the detection time When it is longer than a certain period of time, it is determined that the user has left without recycling the charging cable, and the background staff is reminded to perform manual recycling, or the gear is released by remote control, so that the charging cable is automatically recycled. Moreover, the problem of the charger being stolen can also be avoided.

The transmission mechanism is a link mechanism 92, which cooperates with the motor through the link mechanism. The link mechanism drives the clamping part to clamp or loosen, and a pressure sensor is set. The fixing is tight enough, and on the other hand, it also ensures that the tire of the electric vehicle is prevented from being damaged by the clamping mechanism.

A groove is provided at the clamping part, and a tire pressure gauge is placed in the groove, and the tire pressure gauge is connected with the control module through a measuring tube.

Measure the tire pressure of the electric vehicle to ensure the safety of users. In the clamping mechanism, a tire pressure gauge 9 is placed on the clamping part, and the tire pressure gauge measuring tube is stored inside the fixed part. When the tire is clamped, the tire pressure gauge starts charging The stake is exposed and the measuring tube can be pulled out of the clamp. The user can measure the tire pressure, record the tire pressure information, and feed the tire pressure information back to the control module for information processing. The control module feeds back the tire pressure display table after processing the tire pressure information. If the red light is on, the tire pressure is abnormal; if the green light is on, the tire pressure is normal. After the charging is completed, the tire pressure information is fed back to the user's mobile phone.

A display screen 6 is arranged on the charging pile body, and the display screen is connected with the control module. Different from only displaying the remaining charging time at present, the display module of the present invention will specifically reflect the charging situation. That is to say, it will display the electric vehicle's power status, charging status and other parameters at all times, and at the same time combine the technology of the Internet of Things to provide real-time feedback on charging information and users.

The control module is also provided with an overcharge detection module, which detects the charging state, and sends a charging completion signal to the vehicle owner's terminal through the data transmission module after charging is completed, and simultaneously cuts off the charging operation.

Charging process:

When the user enters the charging area, the vehicle stops according to the charging time requirement. Users with more time can park at the clamping mechanism for normal charging, while users with tight time can park in relatively distant areas for fast charging and parking. Normal charging through the mechanical clamping mechanism ensures the charging situation and avoids charging waste caused by snatching charging resources.

When the user stops at the clamping mechanism, after selecting the normal charging mode, the smart charging pile controls the clamping of the tires. Normal charging mode follows the same subsequent steps as fast charging mode after successful clamping. If the normal charging mode fails to clamp successfully, a warning signal will be issued until the clamping control is completed.

Select the charging interface connection. 60V is the fast charging interface, and 48V is the normal charging interface.

After connecting the charging port, select the payment method through the payment window to scan the code. Such as Alipay, WeChat and other mobile payments. After using the charging pile to scan the code to pay, a charging security account will be automatically created after the payment platform, and the charging situation can be understood in real time.

After the code scanning procedure is completed, the charging pile starts to charge.

Carry out an information processing according to the charging situation.

After the charging is completed, judge according to the charging status. Judgment is fast charging or normal charging.

Fast charging ends the charging task after information processing. For normal charging, the clamping mechanism is first released, and then the charging task is ended after information processing.

(*) Information processing: After the processing of the chip version, there are the following information content, the use status of the clamping mechanism, the use status of the pressure sensor, the charging status of the charging interface, and the display of the charging status (new status - in use or update progress - has ended) and transfer the information to the mobile terminal.

Reservation method:

The idle charging pile transmits the charging status signal and location signal to the surroundings by broadcasting;

The owner of the electric vehicle who wants to charge, after receiving the signal, submits a scheduled charging request to the charging pile, and the charging pile obtains the identification information and reservation information of the owner's client device, and judges the scheduled charging request submitted by the client device. whether to pass;

If the reserved charging request is passed, the charging pile records the order information, locks the clamping mechanism, and no longer broadcasts the charging status signal and position signal; if the reserved information fails, sends a reservation failure message to the client device ;

The client device is close to the reserved charging pile parking space, and the charging pile equipped with the identification information scanning device scans the client device, and verifies the reserved charging request corresponding to the identification information, when the reserved charging request matches the charging pile;

The charging pile sends an unlock command to the clamping mechanism corresponding to the charging pile, and the clamping mechanism receives the operation command from the charging pile, and unlocks so that the electric vehicle can enter the locking mechanism.

At the same time, the appointment time of the charging pile starts from the time when the request is received and confirmed. If the charging pile fails to verify within a certain period of time, it will be regarded as giving up. The charging pile will cancel the reservation request and restart the broadcast signal to avoid malicious reservation or preempting the charging pile. bit phenomenon occurs.

The embodiment should not be regarded as limiting the present invention, and any improvement based on the spirit of the present invention should be within the protection scope of the present invention.
