Description

Technical Field

[0001] The present invention relates to the technical field of electric bicycle charging, and in particular to a hidden charging device for an electric bicycle. Background Art

[0002] Electric bicycles are also called "battery vehicles". They are mechatronic personal transportation vehicles that use batteries as auxiliary energy and are installed on the basis of ordinary bicycles with motors, controllers, batteries, handlebars and other operating components and display instrument systems. In recent years, they have been widely popularized in my country. Because electric bicycles are environmentally friendly and low in energy consumption, they are one of the best transportation products for green environmental protection and purification of air pollution. How to provide the general public with a good ecological environment, so that they can be physically and mentally healthy and have a beautiful living environment, the development of the electric bicycle industry is in line with this trend and is also a tool for sustainable social development.

[0003] However, with the increasing use of electric bicycles, the promotion of electric bicycle charging devices is crucial. Currently, most electric bicycle charging devices are installed on the ground in the form of charging piles. Charging piles installed on the ground have the following problems: 1) When the vehicle is parked, there is a possibility that the vehicle may be bumped or pushed away, which affects the safety of the vehicle itself. 2) During the charging process, other people can park their vehicles near the charging pile and plug the charging wires into other people's vehicles to charge, which affects the charging safety and charging continuity of the original vehicle. 3) Charging piles exposed on the ground always occupy a part of the height space above the ground. When there is a need for passage, it is difficult to adjust, which affects the passage of pedestrians or other bicycles, making the already tight ground space even narrower. 4) When charging using charging piles exposed on the ground, some wires, including charging cables, may be scattered on the ground, which may cause pedestrians to trip or be injured by pets. This not only affects the charging effect but also creates a safety hazard. Therefore, it is urgent to design a hidden charging device for electric bicycles to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: by setting up a hidden structure, the occupation of the space above the ground is reduced when not charging, thereby reducing the impact on the passage of pedestrians or vehicles; when charging, the situation of charging lines and other lines scattered in the space above the ground is reduced, and at the same time, the vehicle can be limited to avoid being knocked over or pushed away and lost. Furthermore, the situation of the charging line being used by others is reduced, thereby reducing the impact on the charging safety and charging continuity of the vehicle itself.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a hidden charging device for an electric bicycle, comprising: two pressure-sensitive plates, two box boxes, two side plates corresponding to the two box boxes, and a base; The two pressure-sensitive plates are arranged on the base for supporting the front wheels and the rear wheels when the vehicle is parked. The two plate boxes are arranged under the base and buried in the ground and are located on both sides of the pressure-sensitive plates supporting the rear wheels. The two plate boxes are each provided with a box opening extending in a direction consistent with the arrangement direction of the two pressure-sensitive plates and connected to the top of the base. A motor is provided at one end of each box opening. The two side panels are both fan-shaped structures, and the two motors are respectively connected to the corresponding side panels for driving the side panels in and out of the corresponding box openings. A plurality of wire bins with openings are provided on the two side panels, and the wire bin openings are provided with bin doors.

After the central controller simultaneously receives the pressure signals from the front and rear wheels and the request interaction signal, the motor drives the side plate to move outward from the box to a specified position and generates a charging position signal. The clamping part clamps the vehicle. After the central controller simultaneously receives the charging position signal and the request interaction signal, the corresponding door of the wire bin opens, and the user takes out the charging wire in the corresponding wire bin for charging. When the user starts the interaction part to settle the bill, a settlement interaction signal is generated. When the user places the charging cable in the corresponding cable compartment and closes the compartment door, a door closing signal is generated. After the central controller receives the settlement interaction signal and the door closing signal at the same time, the clamping part releases the clamp on the vehicle, and the side panel is retracted into the box under the action of the motor, and charging is completed.

[0006] As a preferred technical solution of the present invention, the pressure sensitive plate includes a pressure sensor and a supporting plate connected to the sensing end of the pressure sensor for supporting the wheel. The pressure sensor is arranged in the base, and the central controller is electrically connected to the pressure sensors corresponding to the two pressure sensitive plates respectively.

[0007] This is a preferred technical solution of the present invention, wherein the warehouse door includes a hinge door, an electromagnet, a contact sensor and a magnetic block. The hinge door and the electromagnet are installed on the side panel at the corresponding wire warehouse opening position, the contact sensor is installed on the side panel near the corresponding electromagnet position, the magnetic block is installed on the hinge door at the corresponding position of the electromagnet, and the central controller is electrically connected to the electromagnet and the contact sensor respectively.

When the side panel is located in the corresponding box, one of the rectangular surfaces in the side panel fan-shaped body structure abuts against the wall of the corresponding box, and the other rectangular surface in the side panel fan-shaped body structure blocks the box opening of the corresponding box.

[0011] As a preferred technical solution of the present invention, a cylinder groove is opened on the box wall at the end opposite to the end where the motor is installed in the board box, and the cylinder groove is close to the box mouth. A limit cylinder is arranged in the cylinder groove, and the output end of the limit cylinder is connected to the limit plate. The limit cylinder is electrically connected to the central controller. When the side panel moves outward from the corresponding board box to the specified position, the limit plate can move to the bottom of the corresponding side panel.

[0012] As a preferred technical solution of the present invention, a power interface is also provided on the base, and the charging cable includes a cable body and a multi-head charging head. One end of the cable body is connected to the inner wall of the corresponding cable bin, and the other end of the cable body is connected to the multi-head charging head.

By setting up a pressure-sensitive plate and an interactive part, the side panel will only start to move after the request interaction signal and the pressure signals of the front and rear wheels are received by the central controller at the same time, so as to ensure that the vehicle is in a state suitable for charging before carrying out subsequent charging work, thereby ensuring the safety of vehicle charging. By setting up two side panels in conjunction with the clamping part, the vehicle is clamped during charging under the action of the clamping part, thereby avoiding the occurrence of the vehicle being knocked over or pushed away, ensuring the safety of the vehicle. By setting up different wire bins, the charging needs of vehicles of different brands can be met. Since the wire bin is located on the side panel, the end of the charging cable can be closer to the vehicle, reducing the situation of being used by others. The charging cable is set to charge the vehicle.

[0016] 2. When you want to leave, by setting the settlement interaction signal generated by the interaction unit and coordinating it with the door closing signal when the warehouse door is closed, you can ensure that the vehicle can only leave after the settlement is completed and the charging cable is in the corresponding wire warehouse. On the one hand, this avoids the occurrence of escaping the order, and on the other hand, it prevents the charging cable from being damaged by the side panel moving into the corresponding board box when the charging cable is not put away.

[0017] 3. Since the side panels are located in the corresponding box when not charging, the device exists in the form of a flat base when not charging, reducing the space occupied at a certain height above the ground, so that pedestrians or vehicles can pass normally and avoid affecting their travel.

[0018] 4. Since the charging cable is located near the top of the vehicle when charging, it is retracted into the corresponding cable compartment when not charging, and moves with the side panel to the corresponding box, thus avoiding the situation where the charging cable is exposed when charging or not charging, thereby reducing the possibility of injury by animals or tripping passers-by.
