Description

Technical Field

[0001] The present invention relates to the technical field of charging pile design, and in particular to a safety protection type parking lot charging pile. Background Art

[0002] At present, with the popularity of electric bicycles, parking lots for electric bicycles have been planned under most residential areas and office buildings. In order to facilitate the charging of electric bicycles, charging piles need to be set up in the parking lots. The charging piles are often composed of a control box and multiple sockets. The control box allows people to scan the code to pay, and then the electric bicycle charger plug is connected to the socket to start charging.

[0003] In actual use, the number of sockets is often small, so a first-come, first-served charging method is basically adopted. When all parking spaces with sockets are parked with electric bicycles, electric bicycles driving in from behind cannot drive into parking spaces with sockets.

[0004] At the same time, the existing electric bicycles cannot be pushed after being locked, and the owners in residential areas and office buildings often park their bicycles for a whole day. As a result, the charger plug of the electric bicycle is still connected to the socket after charging is completed, and the electric bicycle that is not in the charging state also occupies the parking space with the socket, which is ultimately not conducive to the efficient use of the charging pile. Summary of the invention

[0005] The object of the present invention is to provide a safety protection type parking lot charging pile, which can automatically remove the electric bicycle from the charging position after charging is completed.

[0006] The above technical object of the present invention is achieved through the following technical solutions: A safety protection type parking lot charging pile, including a strip-shaped bracket located in the parking lot, a control box located in the middle of the bracket, a plurality of sockets located on the bracket and evenly spaced along the extension direction of the bracket, charging positions marked on the ground where each socket is located, pick-up positions marked on the ground behind each charging position, limiting guardrails are provided on both sides of the charging positions and the pick-up positions, an aisle is formed between the charging positions and the pick-up positions, an installation groove is opened on the ground between the charging positions and the pick-up positions, transmission rollers are provided at both ends in the installation groove, a driving motor with an output shaft connected to the end of the transmission roller is provided in one end of the installation groove, sprockets are provided at both ends of the transmission roller, transmission chains with ends meshed with the sprockets are provided in both sides of the installation groove, a conveying chain plate group for conveying the electric bicycles in the charging positions to the pick-up positions is provided between the two transmission chains, a plug pulling-out component for pulling out the charger plug on the socket is provided on the bracket, a controller electrically connected to the driving motor is provided in the control box, and an infrared sensor electrically connected to the controller is provided between the limiting guardrails on both sides of the pick-up position.

[0007] The further setting of the present invention is: Support plates for supporting the lower side of the conveying chain plate group are provided on both inner walls of the installation groove.

[0008] The further setting of the present invention is: The plug pulling-out component includes a connecting rod provided for each conveying chain plate group, a jack opened in the conveying chain plate group for the lower end of the connecting rod to be embedded, a limiting ring provided on the peripheral side of the lower end of the connecting rod and with an outer diameter larger than the inner diameter of the jack, a connecting seat provided at the upper end of the connecting rod and in a "U" shape, a steel sheet provided in the connecting seat, a connecting hole opened in the steel sheet for the two plug-in pieces at the front end of the plug to pass through, elastic bands provided on both sides of the steel sheet and with one end connected to the side of the steel sheet and the other end connected to the connecting seat, the width of the connecting hole is smaller than the length of the front end face of the plug, and a plurality of jacks are provided and are respectively provided on the middle outer walls of a plurality of conveying chain plates in the conveying chain plate group.

[0009] The further setting of the present invention is: The lower end face of the connecting rod is in a spherical shape.

[0010] The further setting of the present invention is: The upper side of the connecting hole is communicated with the outside, a connecting arm is provided on the lower side of the steel sheet, and an elastic buckle in a "U" shape for the middle of the plug to be embedded is provided at the end of the connecting arm away from the steel sheet.

[0011] The further setting of the present invention is: Guide parts bent outward are provided at both ends of the elastic buckle.

[0012] The present invention is further configured as follows: a plastic barrier strip is provided around the connection hole.

[0013] The present invention is further configured as follows: the length of the elastic band is greater than the distance between the side edge of the steel sheet and the inner wall of the connecting seat.

[0014] In summary, the present invention has the following beneficial effects:

[0015] 1. When the electric bicycle that needs to be charged enters the charging parking space, the charger plug is connected to the socket of the corresponding charging parking space, and then charging can begin. When the electric bicycle is fully charged, the controller in the control box receives the charging completion signal and transmits the signal to the drive motor. The drive motor can drive the transmission chain to start transmission through the transmission roller, and the transmission chain can drive the conveyor chain plate group to start transmission. The conveyor chain plate group can drive the electric bicycle in the charging parking space to move toward the access parking space. At the same time, the plug removal component unplugs the charger plug from the socket, and the vacated charging parking space is convenient for the next electric bicycle to enter for charging. At this time, the electric bicycle can be automatically removed from the charging parking space after charging is completed;

[0016] When the infrared sensor senses that the fully charged electric bicycle in the access parking space has not been taken away, the electric bicycle in the charging parking space cannot be moved into the access parking space; when the infrared sensor senses that the electric bicycle in the access parking space has been taken away, the infrared sensor can transmit a signal to the controller, and the controller can transmit the signal to the drive motor, and the drive motor starts to rotate to drive the electric bicycle in the charging parking space to move to the vacant access parking space;

[0017] At the same time, the limiting guardrails set on both sides of the charging parking space and the access parking space can limit the electric bicycles entering the charging parking space, and the limiting guardrails can also play a role in safety protection for the electric bicycles in the charging parking space and the access parking space;

[0018] 2. Using the support plates provided on both inner walls of the mounting groove, the support plates can be used to support the lower side of the conveying chain plate group, thereby facilitating the conveying chain plate group to stably support the electric bicycle;

[0019] 3. When the electric bicycle entering the charging parking space needs to be charged, the lower end of the connecting rod located in the parking space is pulled out from the socket, and then the lower end of the connecting rod is inserted into the socket of the conveyor chain plate below the socket, so that the connecting seat at the upper end of the connecting rod corresponds to the position of the socket, and then the plug-in piece at the front end of the plug is inserted into the socket after passing through the connecting hole of the steel sheet, thereby completing the connection between the charging gun plug and the socket;

[0020] When charging is completed and the electric bicycle needs to be driven to move into the parking space, the connecting rod can be driven by the conveying chain plate group to move into the parking space with the transmission of the conveying chain plate group. At this time, the elastic bands on both sides of the steel sheet can drive the plug on the steel sheet to move toward the side away from the socket, and finally the plug can be unplugged from the socket, thereby completing the automatic unplugging of the plug from the socket;

[0021] Because the elastic band has elastic force, the steel sheet can move left and right, up and down, and forward and backward in the connecting seat, so that the plug on the steel sheet can be quickly connected with the socket;

[0022] 4. The lower end surface of the connecting rod is spherical, and the spherical end surface of the connecting rod can guide the connection between the connecting rod and the socket, which is conducive to the lower end of the connecting rod to quickly correspond to the socket and be inserted;

[0023] 5. When the elastic band on the steel sheet pulls the plug out of the socket, the plug will fall to the ground, where it may be stepped on by pedestrians, which can easily cause the plug to be damaged;

[0024] At this time, the connecting arm on the lower side of the steel sheet is used, and an elastic buckle is provided at one end of the connecting arm away from the steel sheet. The plug is embedded in the elastic buckle from top to bottom, and the plug-in piece of the plug is embedded in the connecting hole from top to bottom. At this time, the elastic buckle can clamp the plug; when the plug is unplugged from the socket, the plug can still stay on the steel sheet, and finally the plug can be prevented from falling to the ground after being unplugged from the socket;

[0025] 6. The outwardly curved guide parts are provided at both ends of the elastic buckle, and the guide parts can facilitate the plug to be quickly and smoothly embedded in the elastic buckle;

[0026] 7. The plastic barrier strips arranged around the connection holes can avoid electrical conduction because the plastic material is an insulating material;

[0027] 8. The length of the elastic band is greater than the distance between the side of the steel sheet and the inner wall of the connecting seat. At this time, the position of the steel sheet in the connecting seat can be adjusted forward and backward without elastic deformation of the elastic band. This is conducive to inserting the plug into the socket without elastic deformation of the elastic band, and avoids the plug being unable to be stably inserted into the socket due to the elastic restoring force of the elastic band.
