[0031] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0032] like Figure 1-Figure 4As shown, a contact pressure type self-powered parking space status acquisition device comprises a pressure plate 1, a shell 2, a pressure generating mechanism, a storage battery 14 and a control circuit board 15, wherein the pressure plate 1 is fixed to the top of the shell 2 by a return spring 3, and the return spring 3 may be multiple, and the return spring 3 is made of a material with high elastic limit, fatigue limit and impact toughness, so that the pressure plate 1 can move downward when under pressure and return to its original state when not under pressure, and the pressure generating mechanism is arranged in the shell 2, and is used to convert the mechanical energy obtained by the pressure plate 1 when the vehicle enters and exits the parking space into electrical energy, and the storage battery 14 is used to convert the mechanical energy obtained by the pressure plate 1 when the vehicle enters and exits the parking space into electrical energy. The battery 14 is used to store the electric energy generated by the pressure generating mechanism and to supply power to the control circuit board 15, and the control circuit board 15 is used to determine the parking status of the parking space according to the electric signal output by the pressure generating mechanism, wherein the control circuit board 15 is provided with an electric energy management module, a signal processing module and a communication module, and the electric energy management module is used to manage the charging and discharging process of the battery 14, and the signal processing module is used to determine the parking status of the parking space and generate parking status change information when receiving the electric signal, and the communication module is used to send the parking status change information to the background server.

[0033] When the above-mentioned parking space status acquisition device is in use, when a vehicle enters the parking space, the mechanical energy obtained by the pressure plate 1 is transmitted to the pressure generating mechanism, converted into electrical energy and transmitted to the battery 14 for storage, and at the same time, the pressure generating mechanism generates an electrical signal, and the control circuit board 15 is powered by the battery 14. When the signal processing module in the control circuit board 15 receives the electrical signal, it determines the parking state of the parking space and generates parking state change information, and then sends the parking state change information to the background server via the communication module; when the vehicle leaves the parking space, the above process also occurs, that is, the mechanical energy obtained by the pressure plate 1 is transmitted to the pressure generating mechanism, converted into electrical energy and transmitted to the battery 14 for storage, and at the same time, the pressure generating mechanism generates an electrical signal, and the control circuit board 15 is powered by the battery 14. When the signal processing module in the control circuit board 15 receives the electrical signal, it determines the parking state of the parking space and generates parking state change information, and then sends the parking state change information to the background server via the communication module.

[0034] The parking state change information refers to the state change of the parking space from idle to occupied or from occupied to idle, that is, a vehicle has entered the parking space or a vehicle has left the parking space. If the default initial state of the parking space is idle, the parking state change information generated by the electrical signal received by the signal processing module for the first time indicates that a vehicle has entered the parking space. Similarly, the parking state change information generated by the electrical signal received by the signal processing module for the second time indicates that a vehicle has left the parking space. The parking state change information generated by the electrical signal received by the signal processing module for the third time indicates that a vehicle has entered the parking space. The content of the parking state change information generated by the electrical signal received by the signal processing module for the Nth time can be deduced accordingly.

[0035] like Figure 2 As shown, a plurality of guide rods 12 are fixed to the bottom of the pressure plate 1, and the guide rods 12 are inserted into the return spring 3, and the lower ends of the guide rods 12 extend into the housing 2. The cooperation between the guide rods 12 and the guide holes provided on the housing 2 can effectively improve the stability of the pressure plate 1 during the up and down movement when the vehicle enters and exits. At the same time, the cross section of the pressure plate 1 is arc-shaped, so that the vehicle can park easily, and the contact area between the pressure plate 1 and the wheel can be increased to prevent the pressure plate 1 from being crushed by the wheel as much as possible.

[0036] In this example, the pressure power generation mechanism includes a driving rod 4, a driving wheel 5, a generator 9, a plurality of supporting wheels 7, a connecting column 8 and a pull rope recovery device 11. The upper ends of the plurality of driving rods 4 pass through the shell 2 and are fixedly connected to the bottom of the pressure plate 1. The lower end of each driving rod 4 is equipped with a driving wheel 5. The generator 9 is fixed to the bottom of the shell 2 and a transmission wheel 9.1 is installed on its rotating shaft. The supporting wheels 7, the connecting column 8 and the pull rope recovery device 11 are fixed to at least one side wall in the length direction of the shell 2. The plurality of supporting wheels 7 and the guide The wheels 10 are arranged on the same horizontal line, the guide wheel 10 is arranged below the support wheel 7, a pull rope 6 is installed in the pull rope retractor 11, and the pull rope 6 is successively passed through the transmission wheel 9.1 and multiple support wheels 7 and then fixedly connected to the connecting column 8. The driving wheel 5 is located between two adjacent support wheels 7 or between the support wheel 7 and the guide wheel 10. When the vehicle enters and exits the parking space, the pressure plate 1 drives the driving rod 4 and the driving wheel 5 to move downward, so that the driving wheel 5 drives the transmission wheel 9.1 to rotate through the pull rope 6 to drive the generator 9 to generate electrical energy.

[0037] The above-mentioned pressure power generation mechanism, when a vehicle does not enter or leave the parking space, the wheels do not roll over the pressure plate 1, the generator 9 does not generate electricity, and no electric energy is transmitted to the battery 14 for storage; when a vehicle enters or leaves the parking space, the wheels of the vehicle roll over the pressure plate 1, and the pressure plate 1 moves downward under pressure, thereby driving the driving rod 4 and the driving wheel 5 to move downward. During the downward movement of the driving wheel 5, the pull rope 6 between two adjacent support wheels 7 or between the support wheel 7 and the guide wheel 10 is pressed down, see the attached Figure 3 , the pull rope 6 drives the transmission wheel 9.1 to rotate to drive the generator 9 to generate electricity. When the vehicle passes the pressure plate 1, the pressure plate 1 is reset under the elastic restoring force of the reset spring 3, and the drive rod 4 and the drive wheel 5 are driven to move upward during the reset. At this time, the pull rope retractor 11 retracts the pull rope 6 to facilitate the next power generation. Since a transmission structure consisting of multiple drive rods 4, multiple drive wheels 5, multiple support wheels 7, a pull rope retractor 11 and a pull rope 6 is used to transmit the mechanical energy obtained by the pressure plate 1, compared with the transmission structure of gears and racks, the travel of the pull rope 6 is greatly lengthened, and more mechanical energy can be transmitted to the transmission wheel 9.1 through the pull rope 6 so that the generator 9 converts more mechanical energy into electrical energy, so that the battery 14 can obtain more electrical energy to power the entire device, effectively ensuring the stability of the system operation.

[0038] In specific implementation, the rope reclaimer 11 can use a coil spring as power to form a structure similar to a tape measure to recycle the rope 6, or use a motor as power to wind the rope 6 inside the rope reclaimer 11. The rope 6 is made of a lightweight and wear-resistant material such as nylon to ensure its service life and facilitate the rope reclaimer 11 to recycle it.

[0039] Preferably, the driving rod 4 is L-shaped, with its vertical end fixedly connected to the bottom of the pressure plate 1, and the driving wheel 5 is arranged at its transverse end, and the angle between the vertical and transverse parts of the driving rod 4 is an obtuse angle, so as to better transmit the mechanical energy obtained by the pressure plate 1.

[0040] from Figure 1 It can be seen that in order to prevent the pull rope 6 from losing contact with the driving wheel 5, the transmission wheel 9.1 and the guide wheel 10 during movement, which may cause the generator 9 to fail to generate electricity normally, a limiting groove 13 adapted to the pull rope 6 is provided on the driving wheel 5, the transmission wheel 9.1 and the guide wheel 10, so that the lateral displacement of the pull rope 6 is limited by the limiting groove 13.

[0041] Preferably, in order to increase the power generation capacity and convert as much mechanical energy of the vehicle entering and exiting the parking space into electrical energy as possible, a pressure generating mechanism is provided on both sides of the length direction of the shell 2, and the return spring 3 is located between the pressure generating mechanisms on both sides.

[0042] Finally, it should be noted that the pressure generating mechanism, the storage battery 14, and the control circuit board 15 can be arranged in an integrated manner or in a separate manner. At the same time, in the specific implementation process, the pressure plate 1 is installed in the parking space or at a position adjacent to the parking space entrance, so that the front wheel or rear wheel of the vehicle can roll over the pressure plate 1 at least once when entering or exiting the parking space.

[0043] To sum up, the parking space status acquisition device described in this embodiment can realize the collection of parking space status information. At the same time, the transmission structure composed of multiple driving rods 4, multiple driving wheels 5, multiple supporting wheels 7, a pull rope retractor 11 and a pull rope 6 greatly lengthens the stroke of the pull rope 6 compared to the transmission structure of gears and racks, and can transmit more mechanical energy to the transmission wheel 9.1 through the pull rope 6 so that the generator 9 can convert more mechanical energy into electrical energy, thereby allowing the battery 14 to obtain more electrical energy, effectively ensuring the stable operation of the system.
