Meanwhile, it should be clear that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0044] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description.

If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0047] In the current traffic environment, in order to protect major highways, bridges and other important transportation facilities, truck weight measurement is often set up at various toll stations or monitoring stations, and overweight and overloaded trucks are punished. In the current transportation system, trucks need to stop and be weighed through facilities such as weight-measuring speed bumps, which greatly reduces transportation efficiency and prolongs transportation time. In addition, all existing weight-measuring devices are extremely expensive and require manual operation to operate the weight-measuring devices for testing, which consumes manpower and material resources.

[0048] In order to solve the existing problems, the present invention provides a self-driving intelligent speed bump device. More importantly, a prominent feature of the device of the present invention is self-driving. When modifying a speed measuring point or a truck mass measurement point, self-driving can save the tedious process of modifying the road surface paving related circuits. Therefore, the present invention combines advanced nano-power generation technology to design a self-driving speed bump to complete a series of detection tasks, thereby improving transportation efficiency while ensuring traffic safety. At the same time, it can also reduce manpower consumption. The present invention takes a weighing sensor as an example to demonstrate the application of the present invention when combined with a weighing sensor. Similarly, the present invention is also compatible with environmental monitoring sensors such as temperature sensors, humidity sensors, and positioning sensors. The protection of the present invention is not limited to weighing sensors. All sensors that use the self-driven power generation principle of the present invention for drive processing are within the scope of patent protection.

[0049] The present invention is applicable to data acquisition devices required in traffic law enforcement or detection processes, such as road condition data such as vehicle weight, air humidity and vehicle flow. In addition, the device can generate electricity without any sensors or other loads, converting the energy generated by the vehicle running over the speed bump into electrical energy and storing it in an external container, and then supplying devices with higher power requirements, such as speed sensors, high-definition cameras, etc., to meet the requirements of self-sufficiency, energy saving and environmental protection.

[0050] A self-driving intelligent speed bump device of the present invention comprises: a power generation device, a pressure gauge 4, two speed bump inclined surfaces 7 and a speed bump lower shell 8, the pressure gauge 4 is installed in the speed bump lower shell 8, the power generation device is installed above the speed bump lower shell 8 and contacts with the top of the pressure gauge 4, the two speed bump inclined surfaces 7 are installed on both sides of the speed bump lower shell 8, the upper surface of the power generation device is a plane, the upper surfaces of the two speed bump inclined surfaces 7 are inclined surfaces, and the cross-sectional shape of the entire speed bump device is trapezoidal; the vehicle drives onto the power generation device through the speed bump inclined surface 7 on one side, and then drives out through the speed bump inclined surface 7 on the other side, wherein power generation and weight measurement are performed simultaneously when the vehicle passes over the upper surface of the power generation device.

[0051] Preferably, the power generation device includes a shell, an outer shell 2, an inner core, a battery box 5 and a development board box 6. The shell is installed in the lower shell 8 of the speed bump. An outer shell 2 is provided inside the shell. Several inner cores are installed inside the outer shell 2. Power generation is performed through the interaction between the inner core and the outer shell 2. The inner core is connected to the pressure gauge 4 through a wire (the wire on the outer shell 2 is grounded); the top plate of the shell is the upper partition 1. The vehicle travels to the upper surface of the upper partition 1 for weight measurement. The bottom plate of the shell is the lower partition 3. The lower partition 3 is in contact with the pressure gauge 4. The battery box 5 and the development board box 6 are both installed inside the lower shell 8 of the speed bump and are both located below the power generation device. The battery box 5 is provided with a battery. The development board box 6 is provided with a development board. The development board has two functions. First, the development board collects data by using the power obtained by power generation, that is, collects data measured by four pressure sensors. After collecting the data, the development board uses the relevant calculation function (existing calculation function) to calculate the real pressure data and converts it into gravity according to the relevant vehicle model. At the same time, the existence of the development board provides the possibility for the expansion of peripherals. For example, data is remotely transmitted to peripherals on the system, alarm peripherals, related warning light peripherals, etc. Second, the use of the development board can effectively save the generated electrical energy, and can be controlled to automatically switch to standby mode when no car passes, thereby improving energy utilization efficiency. The battery and the development board are connected to the inner core through wires. The inner wall of the outer shell 2 is affixed with a layer of copper foil, and the outer surface of the copper foil is affixed with a layer of polytetrafluoroethylene; the outer surface of the inner core is affixed with copper foil, and the inner core with copper foil and the polytetrafluoroethylene on the inner wall of the outer shell 2 generate electricity in a contact-separation manner. In a non-compressed state (no external force), there is a certain distance between the polytetrafluoroethylene layer and the copper foil layer, which is about 1mm. At this time, there is no contact, so no power generation benefit is generated at this time. Under external pressure, the two come into contact, and a certain amount of electrical energy is generated at the moment of squeezing for use by the entire device. When the wheel is above the upper partition 1, since the upper partition 1 is made of high-strength metal material, the slight deformation of the upper partition 1 can be ignored, and the outer shell 2 is made of conductive TPU material, which has good conductivity and elasticity and is a non-rigid part. Therefore, under the action of the upper partition 1, the speed bump is subjected to positive pressure. At this time, all the copper foils on the rigid inner core are in contact with the polytetrafluoroethylene on the elastic outer shell 2, achieving maximum power generation efficiency.

[0052] Specifically, the power generation device of the present invention is a friction nano power generation device. Fig.11 The inner core is installed in Fig.10The inner hole of the shell 2 of the TENG power generation device (friction nano power generation device). Since copper foil and polytetrafluoroethylene are both materials that easily gain and lose electrons. Therefore, the present invention chooses to stick copper foil on the outer surface of the inner core, stick a layer of copper foil on the inner wall of the inner hole of the shell 2, and stick a layer of polytetrafluoroethylene on the outside of the copper foil. The inner core with copper foil and the polytetrafluoroethylene on the inner wall of the inner hole of the shell 2 are contacted and separated to generate electricity. Finally, the generated electricity is conducted into the Figure 3 The pressure gauge 4 is neutralized Figure 6 The development board in the development board box 6 is used directly, and the excess power is stored in Figure 5 In the battery of battery box 5. Figure 2 Middle and lower partition 3 and Figure 3 The inner core of the present invention is cylindrical as a whole, and can be formed by two symmetrical trapezoidal structures in one piece, and the left and right sides of the inner core are grooved, and the cross-sectional shape of the groove is V-shaped.

[0053] Preferably, there are four pressure gauges 4 arranged at the four corners of the bottom of the speed bump lower shell 8, the battery box 5 is located between the two pressure gauges 4 on one side, and the development board box 6 is located between the two pressure gauges 4 on the other side. The pressure gauge 4 includes an upper rubber 9, a lower rubber 11, a connecting block 12, an upper limit plate 10, a lower limit plate 13, a base 14 and a pressure sensor 15. The base 14 has a receiving cavity above, the upper rubber 9 is installed in the receiving cavity, the upper part of the upper rubber 9 extends out of the top of the base 14, the lower partition 3 is in contact with the top of the upper rubber 9, and there is a gap between the upper outer wall of the upper rubber 9 and the top inner wall of the base 14 that is connected to the receiving cavity, and water is injected into the receiving cavity through the gap; the lower rubber 11 is installed below the base 14, and the lower part of the lower rubber 11 is connected to the pressure sensor 15 through the connecting block 12, and the pressure sensor 15 is fixed to the bottom of the base 14. The upper rubber 9 (the outer ring of the upper rubber 9 has a spiral structure, so that the internal instrument can ensure that the internal liquid does not overflow when it is subjected to huge pressure, so that the instrument can fully withstand the huge weight. The lower part of the upper rubber 9 can be a cone structure or a plane structure. The base 14 can be set to a cylindrical structure, the upper limiting piece 10 can be a circular ring structure, and the lower limiting piece 13 can be a disc structure.

[0054] Specifically, in Figure 3In the pressure gauge 4, the upper limit plate 10 is fixed to the top of the base 14 by multiple groups of bolts, and the upper rubber 9 is fixed above the base 14, wherein a through hole is opened in the middle of the upper limit plate 10, and the top of the upper rubber 9 passes through the upper limit plate 10 through the through hole. The lower limit plate 13 fixes the pressure sensor 15 (the lower limit plate 13 and the base 14 are connected and fixed by screws, and the lower limit plate 13 has a card slot for fixing the pressure sensor 15, and the pressure sensor 15 is fixed by the card slot). The connecting block 12 is placed above the pressure sensor 15 as a connecting piece between the lower rubber 11 and the pressure sensor 15. The lower rubber 11 is also provided with a spiral structure similar to the upper rubber 9. The threaded structure plays the same role, which is to ensure that the internal liquid does not overflow when the internal instrument is subjected to huge pressure, so that the instrument can fully withstand the huge weight. The top of the lower rubber 11 can also be a flat or conical structure. A crossbeam is provided below the base 14, and the crossbeam divides the interior of the base 14 into two parts, the upper part being the liquid containing cavity. A stepped through hole is provided in the middle of the crossbeam, which is connected to the liquid containing cavity. The lower rubber 11 and the connecting block 12 are placed in the through hole. The lower limit plate 13 is fixed to the bottom of the base 14 by multiple sets of bolts, and the pressure sensor 15 is fixed between the crossbeam and the lower limit plate 13. The pressure sensor 15 is connected to the connecting block 12 through an elastic gasket on the pressure sensor 15 to achieve uniform downward pressure. The wire of the pressure sensor 15 extends out of the base 14. The pressure sensor 15 can be a piezoresistive sensor, that is, the pressure will change the size of the internal resistance. The present invention measures the weight by detecting the resistance. The upper half of the cavity formed between the upper rubber 9, the lower rubber 11 and the base 14 is the position where the hydraulic liquid exists. After being subjected to external pressure, the upper rubber 9 converts the pressure into liquid pressure, and this liquid pressure acts on the lower rubber 11. The lower rubber 11 then transmits this force to the connecting block 12, which finally acts on the pressure sensor 15 to achieve data measurement. The present invention injects water into the gap above the upper rubber 9 and the base 14, and amplifies the reading of the pressure gauge 4 using the hydraulic principle.

[0055] Preferably, the inclined surface of each speed bump bevel body 7 is an arc surface, wherein the height of the inclined surface of the left speed bump bevel body 7 gradually decreases from right to left, and the height of the inclined surface of the right speed bump bevel body 7 gradually decreases from left to right. The two speed bump bevel bodies 7 are symmetrically arranged about the speed bump lower shell 8. Bumps can be provided on both sides of the speed bump lower shell 8, and the speed bump bevel bodies 7 are plugged into the bumps.

[0056] The present invention provides a novel speed bump device combined with advanced nano-power generation at the main body level. In the absence of any load (referring to the absence of any equipment that consumes power such as a weight measurement unit and a development board, in this device, it can be understood that all the internal development boards are removed. Figure 3 The weighing units are all removed, the outer shell 2 is made higher, the entire space inside the lower shell 8 of the speed bump is filled, and the power generation core is inserted), the device can generate large-scale electricity to a certain extent (the amount of power generation depends on the number of power generation units, and a power generation core and the outer shell 2 made of TPU material on the outside are a power generation unit), and the kinetic energy lost by the car is converted into electrical energy (when the car passes through the speed bump, it causes a certain speed loss. This part of the speed loss is converted into potential energy of the wheel lifting, and part of this potential energy is used for friction power generation of the device), thereby improving energy utilization efficiency. Under load (with relevant power consumption facilities), self-driven weighing and air humidity detection can be realized (by adding a humidity sensor, for example, adding Figure 3 The device of the present invention uses a weighing module other than the one provided on the market, but a low-cost weighing module that combines 3D printing with traditional manufacturing, to achieve functions such as low-cost weighing without losing any function, and to replace the existing road detection devices to a certain extent, and the product has a wider range of uses.

[0057] The device of the present invention can be converted into a self-propelled water surface detection device through waterproof treatment, the lower shell 8 of the speed bump is completely closed, the speed bump bevel body 7 is removed, high buoyancy items are added to the upper partition 1, the pressure gauge 4, the battery box 5, and the development board box 6 are removed, and the entire device is completely turned over so that the high buoyancy items on the upper partition 1 contact the sea surface, and the bottom of the lower shell 8 of the speed bump is connected to an immovable fixed object (such as the bottom of a wooden bridge, etc.), such as the weather quality of the water surface, and the detection of ocean current movement (detected by adding relevant sensors and using relevant existing algorithms), etc., to provide a way for data collection. Its power generation principle and structure can also be applied to the anti-corrosion treatment of ships.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
