DETAILED DESCRIPTION

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation, structure, features and effects of an electric vehicle parking space proposed by the present invention in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0025] It should be noted that when an element is referred to as being “disposed on” or “connected to” another element, it may be directly on the other element or there may be an element in between.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] The specific scheme of an electric vehicle parking space provided by the present invention is described in detail below with reference to the accompanying drawings.

[0028] See also Figures 1 to 3 In order to solve the technical problem that electric vehicles are easily affected by temperature during the charging process, an embodiment of the present invention provides an electric vehicle parking space. When the outdoor temperature is too high, in order to prevent the electric vehicle from spontaneous combustion due to the temperature rise during the charging process, the tarpaulin is automatically pulled and closed by the automatic tarpaulin system, and the temperature in the carport is adjusted by the air conditioner to cool down the carport; when the outdoor temperature is too low, in order to effectively utilize the capacity of the electric vehicle system, the system automatically pulls and closes the tarpaulin, and the temperature in the carport is adjusted by the air conditioner to heat up the carport. The electric vehicle parking space includes a charging pile 100, which is mainly used to supply power to the electric vehicle 10. The parking space also includes a carport, an air conditioner 200 and a tarpaulin system 300. The tarpaulin system 300 includes a guide rail that surrounds the parking space on the top of the carport near the charging pile 100, a traction rope arranged on the guide rail, a slip ring sleeved on the traction rope, a tarpaulin connected to the slip ring, a motor 34 that drives the traction rope, and a tarpaulin control system that controls the motor 34. The slip ring corresponding to the end of the tarpaulin is fixed on the traction rope, and the traction rope is pulled open and closed under the driving action of the forward and reverse rotation of the motor 34. A first limit switch 37 and a second limit switch 38 are provided on the guide rail, which are used to trigger the corresponding limit switch when the tarpaulin is pulled open or closed in place, so that the motor 34 stops running.

[0029] It should be noted that the parking space described in the embodiment of the present invention can be a parking space for parking vehicles, or it can be a charging space for charging electric vehicles.

[0030] Please combine Figure 3, which shows the control circuit of the tarpaulin control system. The tarpaulin control system uses a logic control unit 30 as a control chip, a temperature acquisition unit 31 for detecting the ambient temperature of the parking space, and a first limit switch 37 and a second limit switch 38 installed on the guide rail, which are respectively connected to the input port of the logic control unit 30. The power supplied by the charging pile 100 is supplied to the logic control unit 30 through the conversion of the power module 41. The output port of the logic control unit 30 is connected to the first relay 33 through the first amplifier circuit 32. The normally open switch of the first relay 33 serves as the first power switch of the motor 34 to control the on and off of the charging pile 100 supplying power to the motor 34. When the first power switch is closed, the motor 34 rotates forward. Another output port of the logic control unit 30 is connected to the second relay 36 through the second amplifier circuit 35. The normally open switch of the second relay 36 serves as the second power switch of the motor 34 to control the on and off of the charging pile 100 supplying power to the motor 34. When the second power switch is closed, the motor 34 rotates reversely. The logic control unit 30 is connected to a touch screen 40, which is used to display or input corresponding data information. The logic control unit 30 is connected to the air conditioner via the amplifier circuit 201 and the air conditioner relay 202, and is used to control the air conditioner 200 to start and adjust the temperature.

[0031] When the temperature acquisition unit 31 detects that the ambient temperature is greater than the preset threshold value stored in the logic control unit 30 or the touch screen 40 has a control signal input, the logic control unit 30 determines whether the temperature needs to be adjusted according to the input information. When the temperature needs to be adjusted and the second relay 36 is detected to be not in a working state, the logic control unit 30 turns on the first relay 33 through the first amplifier circuit 32. After the normally open switch of the first relay 33 is closed, the motor 34 rotates forward to drive the awning to close; when the awning is fully closed, the first limit switch 37 is triggered. After receiving the trigger signal of the limit switch, the logic control unit 30 controls the motor 34 to stop running. The logic control unit 30 starts the air conditioner 200 and uses the air conditioner 200 to cool down the temperature in the carport.

[0032] After the logic control unit 30 receives the control signal from the touch screen 40 and detects that the first relay 33 is not in the working state, the logic control unit 30 turns on the second relay 36 through the second amplifier circuit 35. After the normally open switch of the second relay 36 is closed, the motor 34 reverses and drives the awning to be pulled open. When the awning is pulled open to the full extent, the second limit switch 38 is triggered. After the logic control unit 30 receives the trigger signal of the second limit switch 38, the motor 34 is controlled to stop running. The logic control unit 30 turns off the air conditioner 200.
