Description

A tire pressure monitoring device based on vibration power generation during tire compression. Technical Field

[0001] This invention relates to the field of tire pressure monitoring device technology, and in particular to a tire pressure monitoring device based on pressure plate vibration power generation. Background Technology

[0002] Tire pressure monitoring devices use sensors to compare the number of rotations of the tire. A tire with insufficient pressure will have a shorter circumference, thus detecting whether the tire pressure is normal and issuing alarms for tire leaks and low pressure. For example, CN202222709602.7 discloses a solar-powered tire pressure monitoring device, which includes a base and a tire pressure monitoring device body. Support plates are symmetrically welded to the upper end of the base, and the tire pressure monitoring device body is rotatably connected between the two symmetrically distributed support plates via pins. Both sides of the tire pressure monitoring device body are circular. The circumferential array has positioning holes. The beneficial effect of this utility model is that when it is necessary to adjust the angle of the tire pressure monitoring device, first pull the pull ring outward from the fixed block. The pull ring drives the movable rod and the limiting plate to move. The movable rod squeezes the positioning spring, and the limiting plate drives the positioning rod to move out of the positioning hole. At this time, rotate the pull ring. The pull ring drives the movable rod and the limiting plate to rotate. The limiting plate drives the drive gear to rotate. The drive gear drives the sector-shaped internal gear plate to move. The sector-shaped internal gear plate drives the tire pressure monitoring device body to rotate, thereby realizing the adjustment of the angle of the tire pressure monitoring device body.

[0003] Existing built-in tire pressure monitoring systems rely on batteries for power, requiring battery replacement approximately every five years. Replacement necessitates removing the tire, resulting in high costs. Furthermore, built-in systems cannot utilize solar power for continuous self-generation, hindering long-term use. Additionally, different tire pressure settings are required for different vehicle models and tire sizes, making it difficult for a single system to be universally applicable. Moreover, the lack of cushioning in the event of a tire blowout or other sudden impact makes the system susceptible to damage. Summary of the Invention

[0004] This disclosure relates to a tire pressure monitoring device based on pressure plate vibration power generation. By setting an elastic leaf spring, the reciprocating vibration amplitude can be increased to achieve continuous pressure plate vibration power generation, providing power to the tire pressure monitoring device without the need to replace the battery, thus enabling long-term use.

[0005] In a first aspect, this disclosure provides a tire pressure monitoring device based on pressure plate vibration power generation, specifically comprising: a device housing assembly; the device housing assembly includes a valve tube and a main mounting plate, the valve tube being fixedly connected to the bottom surface of the main mounting plate, a piezoelectric ceramic component being mounted on the top surface of the main mounting plate, a through hole being formed inside the main mounting plate, a vibration reinforcement component being mounted beside the through hole and on the top surface of the main mounting plate, a sensor assembly being mounted on the top surface of the main mounting plate and to the left of the through hole, and a buffer assembly, an alarm assembly, and a leaf spring balance calibration component being mounted from left to right on the top surface of the main mounting plate and behind the sensor assembly; the piezoelectric ceramic component is connected to the sensor assembly and the alarm assembly via a circuit.

[0006] In at least some embodiments, the buffer assembly includes a fixed slide rail, a buffer moving block, and a buffer leaf spring. The fixed slide rail is fixedly welded to the top surface of the main mounting plate. The buffer moving block is slidably engaged with the fixed slide rail. A locking connecting sleeve is provided on the buffer moving block. A screw is engaged with the internal thread of the locking connecting sleeve. A groove is formed on the top surface of the buffer moving block along the axial direction of the locking connecting sleeve. The screw is engaged inside the groove. The first end of the buffer leaf spring is engaged with the screw. When the buffer moving block is disturbed by strong airflow fluctuations, the buffer leaf spring will deform, synchronously pushing the buffer moving block to move, converting the impact force into kinetic potential energy for buffering. The buffer leaf spring has a better buffering effect on the impact force as the degree of deformation increases.

[0007] In at least some embodiments, the sensor assembly includes a sensor mounting bracket and a temperature and pressure sensor. The sensor mounting bracket is fastened to the top surface of the main mounting plate by bolts. There are two sensor mounting brackets in total, and the temperature and pressure sensor is snapped between the two sensor mounting brackets. The temperature and pressure sensor is connected to the microprocessor and the central control panel through a circuit.

[0008] In at least some embodiments, the vibration-enhancing component includes a counterweight, an elastic leaf spring, an assembly clip bracket, fastening rods, and a fixing frame assembly. The counterweight is fixedly attached to the top surface of the end of the elastic leaf spring, and the other end of the elastic leaf spring is raised and installed on the top surface of the main mounting plate. Connecting side plates are fixedly connected to the left and right sides of the assembly clip bracket, and the sides of the connecting side plates have concave grooves. Limiting rods are clipped into the grooves, and connecting holes are opened at both ends of the limiting rods. Fastening rods are inserted into the connecting holes, and threaded holes are opened at the opposite ends of the fastening rods. Bidirectional threaded rods are connected to the threaded holes through threaded engagement, and hexagonal nuts are welded onto the bidirectional threaded rods. The fixing frame assembly consists of a first fixing frame and a second fixing frame. The first fixing frame and the second fixing frame are respectively clipped into the grooves of the connecting side plates, and the other ends of the first fixing frame and the second fixing frame are respectively fixedly connected to the main mounting plate by bolts. Rotating the hexagonal nuts on the bidirectional threaded rods drives the two fastening rods to move, thereby fastening the limiting rods into the grooves of the connecting side plates, completing the assembly and fixing.

[0009] In at least some embodiments, the leaf spring balance calibration component includes a fixing block, an adjusting leaf spring, a leaf spring balance support rod, and an adjusting screw. The fixing block is fixedly connected to the top surface of the main mounting plate. The top surface of the fixing block is also provided with a round tube and a screw with the same structure as the locking sleeve. One end of the adjusting leaf spring is sleeved on the screw, and the other end of the adjusting leaf spring is snapped into the end of the moving alarm trigger rod. The leaf spring balance support rod is screwed onto the main mounting plate, and the top end of the leaf spring balance support rod is attached to the bottom surface of the adjusting leaf spring. The adjusting screw is screwed onto the inner protective plate and the top panel, and the bottom end of the adjusting screw is attached to the top surface of the adjusting leaf spring. After assembling and fixing one end of the adjusting leaf spring, the initial position of the moving alarm trigger rod can be adjusted and determined by adjusting the bending degree of the adjusting leaf spring.

[0010] In at least some embodiments, the alarm component includes a fixed support block and a movable alarm trigger rod. Two fixed support blocks are provided, and the movable alarm trigger rod is engaged between the two fixed support blocks. One end of the movable alarm trigger rod is engaged with the second end of a buffer leaf spring. A linkage collar is fixedly sleeved on the movable alarm trigger rod, and a sliding rod is fixedly spot-welded to the linkage collar. A roller is axially engaged at the end of the sliding rod, and the roller is engaged inside a guide plate fixedly disposed on the enclosure.

[0011] In at least some embodiments, the device housing assembly further includes a top panel, which is fixedly and thermally bonded to the top surface of the surrounding panels around the main mounting plate. An inner protective plate is installed below the top panel and is connected to the top surface of the sensor assembly via screws. An inner locking connecting sleeve is externally engaged with the valve tube. A battery and a microprocessor are also installed on the top surface of the main mounting plate. The piezoelectric ceramic component is connected to the battery and the microprocessor via a circuit design. The piezoelectric ceramic component is subjected to vibration, which generates polarization, causing positive and negative charges to appear on two opposing surfaces, resulting in a piezoelectric effect. This allows for power generation, and the electrical energy is stored in the battery to power the tire pressure alarm device.

[0012] This invention provides a tire pressure monitoring device based on compression vibration power generation, which has the following beneficial effects:

[0013] In this invention, an elastic leaf spring is used to increase the reciprocating motion of the piezoelectric ceramic component after it is subjected to the vibration of the tire. This increases the vibration amplitude even on relatively flat roads with uniform driving speed, enabling continuous vibration power generation to power the tire pressure monitoring device without the need to replace the battery, thus achieving long-term use.

[0014] In addition, the limit rod is engaged with the upper and lower sides of the elastic leaf spring, which can adjust the reciprocating amplitude of the elastic leaf spring. This allows the factory vibration amplitude to be adjusted according to the vehicle model, making the power generation efficiency suitable and applicable to various vehicle models. After adjusting the bending degree of the leaf spring, the initial position of the moving alarm trigger rod can be adjusted and determined, so that the movable distance and buffering force of the buffer leaf spring can be adjusted in the initial state, thus making it suitable for tire pressure detection of different vehicle models.

[0015] In addition, when the buffer moving block is disturbed by strong airflow fluctuations, the buffer leaf spring will deform and push the buffer moving block to move in sync, converting the impact force into kinetic potential energy for buffering. The buffer leaf spring has a better buffering effect on the impact force as the degree of deformation increases. When there is no impact force, the buffer leaf spring will automatically recover due to its own elasticity, driving the buffer moving block to automatically reset, thus meeting the permanent use requirements of the device under built-in conditions.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The piezoelectric ceramic component 1203 is connected to the battery 1202 and the microprocessor 1204 by a circuit design. The piezoelectric ceramic component 1203 is subjected to vibration and polarization, which causes positive and negative charges to appear on the two opposite surfaces, resulting in a piezoelectric effect. This allows for the generation of electricity through the vibration of the pressing plate, and the electrical energy is stored in the battery 1202 to power the tire pressure alarm device. The microprocessor 1204 can process information from sensors, alarms, etc., and can also modularize the entire device to reduce its size and adapt to the installation environment.

[0034] In this embodiment of the present disclosure, as shown in Figure 4, the vibration enhancement component 2 comprises a counterweight 21 and an elastic leaf spring 22. The counterweight 21 is fixedly attached to the top surface of the end of the elastic leaf spring 22. The other end of the elastic leaf spring 22 is raised and installed on the top surface of the main mounting plate 12. The elastic leaf spring 22 can increase the reciprocating motion of the piezoelectric ceramic component 1203 after it is subjected to the vibration of the tire, thereby increasing the vibration amplitude on relatively flat and uniform road sections, and realizing continuous pressing vibration power generation.

[0035] In this embodiment, as shown in Figure 5, the vibration-enhancing component 2 further includes an assembly latch bracket 23, a fastening rod 24, and a fixing frame assembly 25. Connecting side plates 2301 are fixedly connected to the left and right sides of the assembly latch bracket 23. A recessed groove is formed on the side of the connecting side plate 2301, and a limiting rod 2302 is latched inside the groove. Connecting holes are formed at both ends of the limiting rod 2302, and fastening rods 24 are inserted into the connecting holes. Threaded holes are formed at the opposing ends of the fastening rods 24, and bidirectional threaded rods 2401 are connected to the threaded holes via threaded engagement.

Rotating the hexagonal nut on the bidirectional threaded rod 2401 drives the two fastening rods 24 to move, thereby fastening the limiting rod 2302 into the groove of the connecting side plate 2301, completing the assembly and fixation. The limiting rod 2302 is snapped into the upper and lower sides of the elastic leaf spring 22, which can adjust the reciprocating spring amplitude of the elastic leaf spring 22.

[0036] In this embodiment of the present disclosure, as shown in Figure 6, the buffer assembly 3 includes a fixed slide rail 31, a buffer moving block 32, and a buffer leaf spring 33. The fixed slide rail 31 is fixedly welded to the top surface of the main mounting plate 12. The buffer moving block 32 is slidably engaged with the fixed slide rail 31. A locking connecting sleeve 3201 is provided on the buffer moving block 32. A screw 3202 is engaged with the internal thread of the locking connecting sleeve 3201. A groove is opened on the top surface of the buffer moving block 32 along the axial direction of the locking connecting sleeve 3201. The screw 3202 is engaged inside the groove. The first end of the buffer leaf spring 33 is engaged with the screw 3202. When the buffer moving block 32 is disturbed by strong airflow fluctuations, the buffer leaf spring 33 will deform and push the buffer moving block 32 to move, converting the impact force into kinetic potential energy for buffering. The buffer leaf spring 33 has a better buffering effect on the impact force as the degree of deformation increases. When there is no impact force, the buffer leaf spring 33 will automatically recover due to its own elasticity.

[0037] In this embodiment of the present disclosure, as shown in Figures 6 and 8, the alarm component 4 includes a fixed support block 41 and a movable alarm trigger rod 42. Two fixed support blocks 41 are provided, and the movable alarm trigger rod 42 is engaged between the two fixed support blocks 41. One end of the movable alarm trigger rod 42 is engaged with the second end of the buffer leaf spring 33. A linkage collar 4201 is fixedly sleeved on the movable alarm trigger rod 42, and a sliding rod 42011 is fixedly spot-welded to the linkage collar 4201. A roller is axially fixedly engaged at the end of the sliding rod 42011. The roller is engaged inside the guide plate fixedly provided on the enclosure plate 1201. By adding an alarm trigger switch inside the guide plate, or adding a tire pressure abnormality alarm trigger switch, when the tire pressure is abnormal or subjected to huge fluctuations such as a tire blowout, the buffer movable block 32 will move, synchronously driving the movable alarm trigger rod 42 to move, and also driving the linkage collar 4201 and the sliding rod 42011 to move, thereby triggering the alarm trigger switch or the tire pressure abnormality alarm trigger switch inside the guide plate and issuing an alarm prompt.

[0038] In this embodiment of the present disclosure, as shown in Figure 8, the leaf spring balance calibration component 5 includes a fixing block 51 and an adjusting leaf spring 52. The fixing block 51 is fixedly connected to the top surface of the main mounting plate 12.

One end of the adjusting leaf spring 52 is sleeved on the screw 3202, and the other end of the adjusting leaf spring 52 is engaged with the end of the moving alarm trigger rod 42. After the screw 3202 is engaged with the top surface of the fixing block 51 and the inside of the round tube, the screw 3202 is rotated through the built-in cross groove to fix it to the round tube, thus completing the assembly and fixation of one end of the adjusting leaf spring 52. After adjusting the bending degree of the adjusting leaf spring 52, the initial position of the moving alarm trigger rod 42 can be adjusted and determined, so that the movable distance and buffering force of the buffer leaf spring 33 can be adjusted in the initial state.

[0039] In this embodiment of the present disclosure, as shown in Figure 8, the leaf spring balance calibration component 5 further includes a leaf spring balance support rod 53 and an adjusting screw 54. The leaf spring balance support rod 53 is screwed onto the main mounting plate 12, and the top end of the leaf spring balance support rod 53 is attached to the bottom surface of the adjusting leaf spring 52. The adjusting screw 54 is screwed onto the inner protective plate 1301 and the top panel 13, and the bottom end of the adjusting screw 54 is attached to the top surface of the adjusting leaf spring 52. After screwing the leaf spring balance support rod 53 and the adjusting screw 54, the initial bending degree of the adjusting leaf spring 52 is limited, so that the initial position of the moving alarm trigger rod 42 is fixed, and the buffer leaf spring 33 is given initial elastic potential energy to cope with the sudden impact force.

[0040] In this embodiment of the present disclosure, as shown in Figure 8, the sensor assembly 6 includes a sensor mounting support frame 61 and a temperature and pressure sensor 62. The sensor mounting support frame 61 is fastened to the top surface of the main mounting plate 12 by bolts. There are two sensor mounting support frames 61, and the temperature and pressure sensor 62 is snapped between the two sensor mounting support frames 61. The temperature and pressure sensor 62 is connected to the microprocessor 1204 and the central control panel through a circuit. When the temperature and pressure sensor 62 senses a change in temperature or tire pressure, the microprocessor 1204 processes the information and transmits it to the central control panel, allowing the driver to observe the tire pressure or temperature detection values ​​through the central control panel, thus realizing tire pressure detection.

[0041] In Example 2, based on Example 1, the external structure formed by the main mounting plate 12, the surrounding plate 1201, the top panel 13, and the inner protective plate 1301 can be molded into an integrated, more rounded shape, thereby reducing the volume and making the device lighter and more integrated to adapt to compact installation environments.

[0042] The working principle of this embodiment is as follows: First, the leaf spring balance support rod 53 and the adjusting screw 54 are screwed according to the vehicle model and tires to adjust the initial bending degree of the leaf spring 52 to be appropriate. Then, the buffer leaf spring 33 is snapped into the end of the screw 3202 and the moving alarm trigger rod 42. The hexagonal nut on the bidirectional threaded rod 2401 is rotated to drive the two fastening rods 24 to move, thereby fastening the limit rod 2302 into the groove of the connecting side plate 2301. The first fixing bracket 2501 and the second fixing bracket 2502 are respectively snapped into the groove of the connecting side plate 2301. The other ends of the first fixing bracket 2501 and the second fixing bracket 2502 are respectively fixed to the main mounting plate 12 by bolts. Thus, the assembly and fixing are completed.

[0043] After passing the valve tube 11 through the valve hole of the wheel hub, the inner locking connecting sleeve 1101 is screwed to secure the valve tube 11 to the wheel hub. With the help of external connecting angle steel and other components, the device housing assembly 1 is fixedly installed. When the tire pressure is abnormal, the buffer moving block 32 will move, which will drive the moving alarm trigger rod 42 to move, and also drive the linkage collar 4201 and sliding rod 42011 to move, thereby triggering the tire pressure abnormality alarm trigger switch inside the guide plate and issuing an alarm prompt.
