Description

Technical Field

[0001] The present invention belongs to the technical field of parking equipment, and in particular relates to a self-powered parking space flat plate lock system and a parking space. Background Art

[0002] In modern urban construction, with the rapid increase in the number of cars, the problem of parking difficulties has become increasingly prominent, and the demand for efficient, intelligent and environmentally friendly parking management systems has also increased. Although traditional parking management equipment, such as parking meters, POS machines and high-position cameras, have alleviated the pressure of parking management to a certain extent, they are often limited by the stability of network connections, dependence on manual operations and high maintenance costs. In contrast, parking lot flat panel locks have gradually become the new favorite in the field of parking management with their advantages of independent operation, high security and stability.

[0003] Existing tablet lock technology still faces many challenges. First, traditional tablet locks generally rely on AC power or built-in batteries, which not only increases energy consumption, but also increases the burden of regular charging or battery replacement, which not only increases maintenance costs, but also brings operational inconvenience. Especially in remote parking lots or those with difficult access to electricity, this power supply method is even more limited. Secondly, even if some tablet lock systems use solar power supply in order to achieve energy self-sufficiency, a single solar power supply has the problem of unstable power supply, especially in rainy weather or areas with insufficient light, its efficiency is greatly reduced, and it is difficult to meet the needs of continuous and stable operation. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention provides a self-powered parking space flat panel lock system and a parking space, which can reduce the dependence on traditional energy, reduce operating costs, and provide a stable and environmentally friendly energy supply for the flat panel lock of the parking space.

[0005] In order to solve the above technical problems, the present invention is implemented by the following technical solutions: According to a first aspect of the present invention, a self-powered parking space flat plate lock system is provided, comprising a flat plate lock body arranged on a parking space and a plurality of piezoelectric sheets buried in the parking space, wherein a solar panel and a battery are arranged on the flat plate lock body, the plurality of piezoelectric sheets and the solar panel are electrically connected to the battery respectively, and the battery is electrically connected to a driving motor of the flat plate lock body.

[0006] In a possible implementation of the first aspect, the piezoelectric sheets are long strip-shaped piezoelectric sheets, and the length direction of each of the piezoelectric sheets is parallel to the width direction of the parking space, and a plurality of the piezoelectric sheets are evenly spaced and buried near both ends of the parking space.

[0007] In a possible implementation manner of the first aspect, a distance between two adjacent piezoelectric sheets located at the same end of the parking space is 35 cm to 45 cm.

[0008] In a possible implementation manner of the first aspect, the length of the piezoelectric sheet is 2.3 m to 2.5 m, and the width of the piezoelectric sheet is 18 cm to 22 cm.

[0009] In a possible implementation manner of the first aspect, the piezoelectric sheet is buried at a depth of 4 cm to 6 cm.

[0010] In a possible implementation of the first aspect, a power management module is further provided on the flat lock body, and the output ends of the piezoelectric sheets and the solar panels are electrically connected to the input end of the power management module, and the output end of the power management module is electrically connected to the battery. The power management module is used to adjust whether the piezoelectric sheets and the solar panels charge the battery according to the storage capacity of the battery.

[0011] In a possible implementation manner of the first aspect, a piezoelectric constant of the piezoelectric sheet is 300 pC / N to 600 pC / N.

[0012] In a possible implementation manner of the first aspect, the piezoelectric sheet adopts lead zirconate titanate ceramic piezoelectric material.

[0013] In a possible implementation of the first aspect, the solar panel is disposed on an upper surface of a shell structure of the flat-panel lock body located at a side edge of the parking space, and the battery is disposed in the shell structure.

[0014] According to a second aspect of the present invention, a parking space is provided, on which the self-powered parking space flat panel lock system is arranged.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: The present invention proposes a self-powered parking space flat plate lock system. Because when a vehicle enters and exits a parking space, the friction between its tires and the ground, the change in the weight of the vehicle, etc., will release considerable mechanical energy. The present invention effectively utilizes the mechanical energy generated when the vehicle enters and exits the parking space by burying a number of piezoelectric sheets in the parking space. These mechanical energies are converted into electrical energy by the piezoelectric sheets and stored in the battery, which not only realizes the recycling and reuse of energy, but also improves the energy utilization efficiency of the system. At the same time, the solar panel, as another important energy collection component, can capture and utilize solar energy around the clock. Since the system adopts a dual energy collection mechanism (piezoelectric effect and solar energy), the two complement each other, which improves the reliability of the system. Even if one of the energy collection methods fails or the efficiency decreases, the other method can ensure the normal operation of the system. Therefore, the present invention realizes the self-power supply of the parking flat plate lock system by combining the piezoelectric effect and solar energy technology, greatly reduces the dependence on external power supply, improves the independence of parking equipment, and the system can operate normally even in power outages or remote areas.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Combination Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a self-powered parking space flat plate lock system, which aims to realize self-sufficient power supply of the flat plate lock system by comprehensively utilizing solar energy and mechanical energy generated when the vehicle is running, thereby improving the reliability of the flat plate lock system and reducing the operating cost. The self-powered parking space flat plate lock system includes a flat plate lock body 2 arranged on the parking space 1 and a plurality of piezoelectric sheets 3 buried in the parking space 1. A solar panel 4 and a battery 5 are arranged on the flat plate lock body 2. The plurality of piezoelectric sheets 3 and the solar panel 4 are electrically connected to the battery 5 respectively, and the battery 5 is electrically connected to the driving motor of the flat plate lock body 2.

[0022] Specifically, the flat lock body 2 is installed at a designated position of the parking space 1, usually installed in the middle position of the parking space 1, to control the locking and unlocking of the parking space. It should be understood that the flat lock body 2 is integrated with a control circuit board, a drive motor and necessary sensors and other components to achieve automatic operation, which will not be described in detail in this application. Several piezoelectric sheets 3 are buried under the ground of the parking space 1, and the specific location is selected in an area where the vehicle tires may pass and can produce sufficient pressure changes. The piezoelectric sheet 3 uses the piezoelectric effect to convert the mechanical energy applied by the tires to the ground when the vehicle is driving into electrical energy. These piezoelectric sheets 3 are connected to the battery 5 through wires to store the generated electrical energy. The solar panel 4 is installed on the top or side of the flat lock body 2 to maximize the sunlight. The solar panel 4 converts solar energy into DC power and is connected to the battery 5 through a wire to provide additional power support for the flat lock system. As an energy storage element of the flat lock system, the battery 5 is responsible for storing the electrical energy from the piezoelectric sheet 3 and the solar panel 4, and supplies power to the drive motor of the flat lock body 2 when necessary. It should be noted that the storage battery 5 has sufficient capacity to ensure that the system can still operate normally under continuous rainy weather or low light conditions.

[0023] When the vehicle enters or exits the parking space 1, the change in pressure exerted by the tire on the ground causes the piezoelectric sheet 3 to deform, thereby generating electrical energy. At the same time, the solar panel 4 continues to receive sunlight and converts solar energy into electrical energy. Both parts of electrical energy are transmitted to the battery 5 through wires for storage. The battery 5 stores and manages the received electrical energy to ensure that it can stably supply power to the drive motor of the flat-panel lock body 2 when needed. Exemplarily, the battery 5 also has an intelligent charging protection function to prevent damage to the battery due to overcharging or over-discharging. When the flat-panel lock body 2 receives an unlocking or locking command (such as sent by a remote control, a mobile phone APP or a parking lot management system), the control circuit board in the flat-panel lock body 2 will start the drive motor and drive the flat-panel lock to perform the corresponding action. At this time, the battery 5 provides the required electrical energy for the drive motor.

[0024] In summary, the self-powered parking space flat lock system proposed in the present invention realizes self-sufficient power supply of the system through the comprehensive utilization of solar energy and mechanical energy. The system not only improves the efficiency of parking management, but also significantly reduces the operating cost and environmental burden, and has broad application prospects and market value. Traditional parking space lock systems often rely on external power supply. Once the power supply is interrupted, the system will not work normally. The self-powered system of the present invention effectively avoids this problem. Even in the event of an external power failure, the system can continue to provide power support for the drive motor through the built-in battery, ensuring the normal execution of the lock control function.

[0025] In one possible implementation, combining Figure 1 and Figure 2 As shown, the piezoelectric sheets 3 are long strip-shaped piezoelectric sheets, and the length direction of each piezoelectric sheet 3 is parallel to the width direction of the parking space 1 , and a number of piezoelectric sheets 3 are evenly spaced and buried near both ends of the parking space 1 .

[0026] That is to say, the piezoelectric sheet 3 is designed to be long and strip-shaped. The selection of this shape is based on two main considerations: first, the long strip shape can more effectively cover the area where the vehicle tire may pass through, increasing the chance of contact between the tire and the piezoelectric sheet 3; second, when the long strip shape is subjected to pressure, its deformation in the length direction is more significant, which is conducive to generating a larger potential difference and current output. In order to maximize the energy collection efficiency, the length direction of each piezoelectric sheet 3 is designed to be parallel to the width direction of the parking space 1. The advantage of this layout is that when the vehicle enters or exits along the length direction of the parking space 1, both the front and rear wheels will press over the piezoelectric sheet at a nearly vertical angle, thereby maximizing the pressure application area and pressure duration of the tire on the piezoelectric sheet 3. In addition, several piezoelectric sheets 3 are evenly spaced and buried near the two ends of the parking space 1 to ensure that no matter where the vehicle is parked, its wheels can press over the piezoelectric sheet 3 multiple times during the process of entering and exiting, thereby activating the piezoelectric material multiple times to generate current pulses. This layout not only improves the energy collection efficiency, but also makes the energy output of the system more stable and reliable.

[0027] It should be noted that the spacing between the piezoelectric sheets 3 must ensure that each wheel can press over at least one piezoelectric sheet 3 during the vehicle's driving, and that there will be no pressure leakage due to excessive spacing. At the same time, the buried depth of the piezoelectric sheets 3 must also be properly controlled, ensuring that the vehicle tire can fully compress the piezoelectric sheets 3 to produce sufficient deformation, while avoiding being too deep so that the tire cannot reach it.

[0028] Exemplarily, all piezoelectric sheets 3 are connected to the storage battery 5 via waterproof and wear-resistant cables. The cables are buried in the parking space 1, and the arrangement of the part that cannot be buried needs to avoid the vehicle driving path to avoid being crushed and damaged.

[0029] In summary, in this embodiment, the self-powered parking space flat panel lock system can more effectively collect and utilize the mechanical energy generated when the vehicle is driving, provide stable and reliable power support for the flat panel lock system, thereby improving its self-sufficiency.

[0030] In one possible implementation, combining Figure 1 As shown, the spacing between two adjacent piezoelectric sheets 3 located at the same end of the parking space 1 is 35cm~45cm. Too small a spacing will cause the piezoelectric sheets to be too dense, resulting in too many overlapping triggers during vehicle driving, increasing the processing burden of the system; too large a spacing will not be able to fully cover the driving trajectory of the vehicle tires, resulting in insufficient energy collection.

[0031] That is, the spacing between two adjacent piezoelectric sheets 3 at the same end of the parking space 1 is set to be within the range of 35cm to 45cm. The selection of this spacing range is based on extensive research and data analysis of the wheelbases of different vehicle models. The wheelbases of modern vehicles (i.e., the distance between the center lines of the wheels on the same side) are mostly concentrated in a certain range, but they also vary depending on factors such as the vehicle model and purpose. Therefore, by setting such a flexible spacing range, it can be ensured that the wheels of most vehicles can effectively press over at least one piezoelectric sheet when entering or exiting a parking space, thereby triggering the energy collection mechanism. Therefore, the spacing range of 35cm to 45cm is an optimized choice after a trade-off.

[0032] In summary, by controlling the distance between two adjacent piezoelectric sheets 3 located at the same end of the parking space 1, it is ensured that the system can adapt to the changes in wheelbases of different vehicle models, while optimizing the energy collection efficiency and facilitating construction and maintenance.

[0033] In one possible implementation, combining Figure 1 As shown, the length of the piezoelectric sheet 3 is 2.3 m to 2.5 m, and the width of the piezoelectric sheet 3 is 18 cm to 22 cm.

[0034] Specifically, the length of the piezoelectric sheet 3 is set to be within the range of 2.3m to 2.5m. The length is selected based on the standard size of the parking space 1 and the rolling track of the vehicle tire. Generally speaking, the width of a standard parking space is between 2.4m and 2.7m, and the vehicle tire will have a certain offset and swing during driving. Therefore, setting the length of the piezoelectric sheet 3 within this range can ensure that no matter how the vehicle is parked, its tire can effectively contact the piezoelectric sheet when entering or exiting the parking space, thereby triggering the energy collection mechanism. The width of the piezoelectric sheet 3 is set to be within the range of 18cm to 22cm, and the width is also selected based on the contact area of ​​the vehicle tire and the energy output efficiency of the piezoelectric sheet 3. A piezoelectric sheet 3 that is too narrow cannot fully cover the contact area of ​​the tire, resulting in insufficient energy collection; while a piezoelectric sheet 3 that is too wide increases the material cost. By setting it within this width range, the cost can be controlled while ensuring the energy collection efficiency. In addition, the width also ensures that the piezoelectric sheet 3 can produce sufficient deformation when subjected to tire pressure, thereby outputting a stable current pulse.

[0035] In summary, by controlling the length and width of the piezoelectric sheet 3, it is ensured that the self-powered parking space flat-plate lock system can efficiently collect and utilize the mechanical energy generated when the vehicle is traveling, while taking into account the cost-effectiveness of the system.

[0036] For example, the length of the piezoelectric sheet 3 is set to 2.5m, the width is set to 20cm, and the spacing is set to 40cm. The power of the solar panel 4 is 300W, and the battery 5 uses a 10Ah lithium battery, which can provide stable power supply to ensure the normal operation of the tablet lock system.

[0037] In one achievable method, the buried depth of the piezoelectric sheet 3 is 4 cm to 6 cm. Specifically, the buried depth can ensure that the piezoelectric sheet 3 can stably deform and output electrical energy when subjected to the pressure of the vehicle tire, and will not be affected by slight fluctuations or unevenness of the ground surface. Secondly, the buried depth also takes into account the need to protect the piezoelectric sheet 3 from external physical damage, such as preventing it from being pierced by sharp objects or malicious damage. The vehicle tire will have a certain degree of compression and rebound during driving, so the buried depth of the piezoelectric sheet 3 needs to be able to accommodate this deformation. The depth range of 4 cm to 6 cm can ensure that the tire produces sufficient deformation to trigger the energy collection mechanism when pressing over the piezoelectric sheet 3, and can also avoid unnecessary energy loss or system damage caused by the tire being pressed too deep.

[0038] In one possible implementation, combining Figure 1 , Figure 2 and Figure 3 As shown, a power management module 6 is also provided on the flat lock body 2, and the output ends of the piezoelectric sheets 3 and the solar panels 4 are electrically connected to the input end of the power management module 6, and the output end of the power management module 6 is electrically connected to the battery 5. The power management module 6 is used to adjust whether the piezoelectric sheets 3 and the solar panels 4 charge the battery 5 according to the storage capacity of the battery 5.

[0039] Specifically, the power management module 6 is responsible for monitoring and managing the energy flow of the entire system. An important function of the power management module 6 is to intelligently adjust whether the piezoelectric sheet 3 and the solar panel 4 charge the battery 5 according to the power storage capacity of the battery 5. Specifically, when the power of the battery 5 is lower than the preset threshold, the power management module 6 will start the charging mode, allowing the output power of the piezoelectric sheet 3 and the solar panel 4 to flow into the battery 5 for charging. When the power of the battery 5 reaches or exceeds the set upper limit, the power management module 6 will cut off the charging path to prevent overcharging, thereby protecting the service life of the battery 5.

[0040] Preferably, the piezoelectric constant of the piezoelectric sheet 3 is 300pC / N~600pC / N. The piezoelectric constant (in pC / N) is an important parameter to measure the ability of a piezoelectric material to generate electric charge when subjected to mechanical stress. It reflects the efficiency of the piezoelectric material in converting mechanical energy into electrical energy. In this embodiment, the piezoelectric constant of the piezoelectric sheet 3 is set to be within the range of 300pC / N to 600pC / N, ensuring that the piezoelectric sheet 3 can generate sufficient electrical energy output under the pressure of the vehicle tire to meet the working requirements of the system.

[0041] More preferably, the piezoelectric sheet 3 uses lead zirconate titanate (PZT) ceramic piezoelectric material. PZT is a typical piezoelectric ceramic material with excellent piezoelectric properties, high electromechanical coupling coefficient and stability. PZT can effectively convert mechanical stress into electrical energy output, and has good weather resistance and corrosion resistance, and is very suitable for self-powered systems in outdoor environments. In detail, PZT has a high piezoelectric constant and sensitivity, which can ensure that the piezoelectric sheet 3 can generate significant electrical energy output even when subjected to less pressure. In addition, PZT also has a high Curie temperature and good stability, and can maintain stable piezoelectric properties over a wide temperature range.

[0042] In one possible implementation, Figures 1 to 3 As shown, the solar panel 4 is arranged on the upper surface of the shell structure of the flat lock body 2 located at the side edge of the parking space, and the battery 5 is arranged in the shell structure.

[0043] Specifically, the solar panel 4 is arranged on the upper surface of the shell structure of the flat lock body 2 located at the side edge of the parking space. This arrangement makes full use of the vertical space at the side edge of the parking space 1 and does not occupy additional ground area. Secondly, placing the solar panel 4 on the upper surface can ensure that it can receive sunlight to the greatest extent and improve the efficiency of solar energy collection. On a clear day, the solar panel 4 can continuously convert solar energy into electrical energy, providing stable energy support for the system. The battery 5 is arranged inside the shell structure, which effectively protects the battery 5 from interference and damage from the external environment (such as rain, dust, malicious damage, etc.).

[0044] The embodiment of the present invention also provides a parking space, which is provided with the above-mentioned self-powered parking space flat-panel lock system. That is to say, the parking space adopts the self-powered parking space flat-panel lock system, which can realize the lock control function without an external power supply. Through the combined effect of the piezoelectric sheet and the solar panel, the system can efficiently collect and utilize the mechanical energy generated by the vehicle when it is driving and the solar energy in nature, thereby improving the energy utilization efficiency and reducing the installation cost. The parking space solves the problem that the traditional parking space lock system relies on an external power supply, and provides a more effective implementation plan for parking management in modern cities.

[0045] It should be noted that the parking spaces use standard sizes and markings to ensure that vehicles are parked in accordance with regulations.
