Description

Technical Field

[0001] The invention belongs to the technical field of electric vehicle charging piles and relates to a charging estimated time display device. Background Art

[0002] As electric vehicles become more and more popular, the demand for public charging piles is also growing. They are mainly installed on the ground or walls of public buildings and residential parking lots. Public charging piles are mainly installed on the ground. The charging piles are usually equipped with smart displays to achieve human-computer interaction. The display can display data such as charging amount, cost, and charging time.

[0003] For example, Chinese invention patent application [201711201897.4] discloses a multifunctional new energy vehicle charging pile, including a power outlet and a charging pile, wherein the charging pile is installed above a base, and a human-machine interactive display screen is provided on the side of the base close to the charging parking area, an electronic charging microwave transmitter is provided above the human-machine interactive display screen, and a card swiping area is provided below the human-machine interactive display screen, and a fault detector is provided below the card swiping area, and an entertainment display screen is newly added at the top, so that the car owner can pass the time on the entertainment display screen while waiting; and a safety lock is installed on the charging gun, so that the car owner can lock the charging gun to the car body through the safety lock when he needs to leave, effectively preventing other car owners from taking the charging gun away when the car owner is not there, thereby affecting the charging of his own car. Especially in some larger charging areas, due to the shortage of charging positions, many car owners are waiting in line or driving back and forth to patrol and observe, hoping to be lucky enough to encounter a fully charged car. However, the current display screen is small, and the car owners patrolling and observing cannot know the remaining charging time at the first time. They need to get off the car and walk to the display screen to see it clearly. Therefore, there is an urgent need for a method that can let the car owners queuing or patrolling know the remaining charging time at the first time. Summary of the invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a charging estimated time display device with a liftable warning light head, so that passing drivers can understand the remaining charging time required for the car being charged from a distance.

[0005] The object of the present invention can be achieved through the following technical solutions: A charging estimated time display device, comprising a charging pile, a power box, and the power box is connected to a charging gun through a charging line, and the power box is fixed on the side of the charging pile, characterized in that a U-shaped shielding plate is welded and fixed on the upper end of the charging pile, and a horizontally arranged water baffle and a mounting plate are fixed in the charging pile, the water baffle is located above the mounting plate, and a strip hole is opened above the shielding plate, and a sealing plate is hinged on one side of the strip hole, and a cylinder is fixed on the water baffle, and a vertically arranged plate-shaped prompt lamp head is fixed on the telescopic rod of the cylinder, and a plurality of lamp beads distributed in a matrix are fixed on the end surface of the prompt lamp head, a control circuit board and a fan are fixed on the mounting plate, and a heat dissipation hole aligned with the fan is opened on the side of the charging pile, and the prompt lamp head, the fan, and the cylinder are connected to the control circuit board through a wire, and a water drop hole is opened on the water baffle, and a drain pipe docked with the water drop hole is connected to the lower end of the water baffle, and a water outlet pipe that horizontally penetrates the charging pile is fixed at the lower end of the charging pile, and the drain pipe is connected to the water outlet pipe, and the side of the power box is connected to the side of the charging pile through a through hole.

[0006] Furthermore, it also includes an anti-collision mechanism, which includes a long anti-collision plate, an alarm plate, a spring and an extrusion column. Several extrusion columns are fixed on the inner side of the anti-collision plate. The extrusion column is provided with an annular retaining edge. A sliding hole for the extrusion column to pass through is opened on the front end surface of the charging pile. The alarm plate is vertically fixed in the charging pile. The alarm plate is provided with several switch buttons. The spring is sleeved on the extrusion column. One end of the spring rests on the alarm plate, and the other end rests on the annular retaining edge. A buzzer alarm is fixed on the outside of the charging pile. The buzzer alarm and the switch button are electrically connected to the control circuit board.

[0007] In order to prevent the car from colliding with the charging pile when parking, an anti-collision mechanism is set up. When the anti-collision plate is squeezed by the car, the spring gives it a buffering function. The anti-collision plate drives the squeezing column to move into the charging pile. When the squeezing column squeezes the switch button, the buzzer alarm sends an alarm signal because the switch button is powered on, reminding the driver.

[0008] Furthermore, an advertising cloth is pasted on the outer side of the anti-collision plate.

[0009] Furthermore, solar panels are fixed on both sides of the upper end surface of the shielding plate, and batteries are fixed on the mounting plate, and the solar panels are connected to the batteries. The solar panels can absorb sunlight to convert into electrical energy, and the batteries can store the electrical energy generated by the solar panels. This technology is an existing mature technology and will not be described in detail again. The batteries provide additional power for the fan and the cylinder.

[0010] Furthermore, the power box has a display screen that displays the charging time, the charged amount, the fee, and the time required to fully charge.

[0011] Furthermore, the power box is also equipped with a speaker, which is located below the display screen. When fully charged, the speaker will play a prompt voice or music to let the owner drive away and free up the charging space to avoid occupying the charging pile for a long time.

[0012] Furthermore, the lamp beads are arranged in 5 horizontal rows and 6 vertical columns. The number of lamp beads is used to display the remaining charging time required for the car being charged to be fully charged. One energized and glowing lamp bead represents 10 minutes, and a row of glowing lamp beads represents 1 hour. Other passing cars can see the number of lamp beads and understand how much time is needed to fully charge.

[0013] When the charging gun is plugged into the electric vehicle for normal charging, the control circuit board will start the cylinder, push the warning lamp head out of the bar hole, push open the sealing plate, and the lamp beads on the warning lamp head will light up, so that passing drivers can know the required time from a distance without getting off the car to check. When the charging gun is pulled out, it means that the charging pile is idle, then the cylinder will move the warning lamp head down into the charging pile, and the sealing plate will cover the bar hole due to gravity to prevent dust or rain from entering the charging pile.

[0014] Compared with the prior art, the present charging estimated time display device has the following advantages:

[0015] 1. With a retractable warning light head, other drivers who need to charge can know the remaining charging time of the car being charged from a distance, so that the driver can find a charging pile with a shorter remaining time as soon as possible without having to get off the car to check the display screen.

[0016] 2. With anti-collision mechanism, when the car squeezes the anti-collision plate, a honey alarm sound will be generated to remind the driver. BRIEF DESCRIPTION OF THE DRAWINGS
