Description

Technical Field

[0001] This invention belongs to the field of power supply device technology, specifically a power supply device for an intelligent tire internal sensor. Background Technology

[0002] As is well known, most existing smart tires monitor temperature and pressure, which have low sampling frequency and low power consumption. The internal battery can meet the power supply requirements of the sensor. With the increasing requirements for intelligent tires, their functions are not limited to tire pressure and temperature, but also include real-time monitoring of tire wear, load, and other functions.

[0003] Because the intelligent tire signal sampling frequency for real-time tire status detection is high and the internal sensors consume a lot of power, the existing internal battery power supply method cannot meet the long lifespan requirements of intelligent tires. Therefore, an internal sensor power supply device for intelligent tires has been developed.

[0004] However, existing power supply devices for internal sensors in smart tires have certain shortcomings: First, although existing devices use bolts to install the wheel-core electromagnetic generator, vibration and other external factors can cause these bolts to loosen over time, leading to weak stability of the generator. Furthermore, most bolts are exposed, making them prone to corrosion over time. Second, to ensure a sufficient power supply, existing devices use wires and cables for power transmission. However, wind and other external forces can easily cause these wires and cables to become tangled. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to provide a power supply device for an intelligent tire internal sensor in order to solve the above-mentioned problems, thereby resolving the issues mentioned in the background art.

[0006] To address the above problems, the present invention provides a technical solution:

[0007] A smart tire internal sensor power supply device includes a rim body, a tire body, a sensor body, an energy storage device, a wheel core electromagnetic generator, wires, a limiting mechanism, and a mounting mechanism. The tire body is mounted on the rim body, the sensor body is mounted inside the tire body, and the energy storage device is mounted inside the tire body. The energy storage device is electrically connected to the sensor body. The wheel core electromagnetic generator is in contact with the rim body. Wires are shared by the wheel core electromagnetic generator and the energy storage device, and the wires are in contact with both the tire body and the rim body. A limiting mechanism is provided on the rim body, and the mounting mechanism is shared by both the rim body and the wheel core electromagnetic generator.

[0008] Preferably, the limiting mechanism includes a limiting cover, a plug, a slot, a guide rod, a guide cylinder, a spring, an end plate, a rubber pad, a top plate, and a locking block. The limiting cover contacts the wheel rim body and is in contact with a wire. A plug is fixedly connected to the limiting cover and is slidably connected to the wheel rim body. A slot is provided inside the plug. A guide rod is fixedly connected inside the wheel rim body. A guide cylinder is slidably sleeved on the outer side of the guide rod. A spring is provided on the outer side of the guide rod. An end plate is slidably sleeved on the outer side of the guide rod and is fixedly connected to the guide cylinder. A rubber pad is adhered to the end plate. A top plate is fixedly connected to the end plate. The rim body is slidably connected, the top plate contacts the insert block, and a locking block is fixedly connected to the top plate. The locking block is slidably connected to the slot. By pushing the rubber pad to move away from the insert block, the end plate is moved. The end plate is forced to push the guide cylinder to slide along the surface of the guide rod. The spring is deformed by the force, and the end plate can move the top plate, which in turn moves the locking block. Then, the limiting cover is pushed to contact the rim body, so that the rim body contacts the wire and drives the insert block to be inserted into the rim body. Then, the end plate is released to allow the spring to return to its original deformation, so as to push the locking block into the slot. The insert block is limited, so that the limiting cover is in a stable position and the problem of wire scattering is avoided.

[0009] Preferably, two inserts are provided, and the two inserts are symmetrically distributed on the limiting cover. The limiting cover can be installed and used by means of the inserts.

[0010] Preferably, one end of the spring is welded to the guide cylinder, and the other end of the spring is welded to the rim body. The guide cylinder can be connected and used by means of the spring.

[0011] Preferably, the mounting mechanism includes a fixing ear, a bolt, a limiting groove, an end rod, a limiting plate, a sliding plate, an elastic airbag, a protective cover, a insert plate, a metal spring, and a retaining ball. The fixing ear is fixedly connected to the wheel core electromagnetic generator. A bolt is movably connected within the fixing ear. The bolt is threaded to the wheel rim body. A limiting groove is formed within the bolt. An end rod is slidably connected within the fixing ear. A limiting plate is fixedly connected to the end rod. The limiting plate is slidably connected to the fixing ear and to the limiting groove. A sliding plate is fixedly connected within the fixing ear. The slide plate and end rod are slidably connected. By pulling the end rod away from the fixed ear, the end rod slides along the surface of the slide plate. The elastic airbag deforms under force, and the end rod moves the limiting plate, pushing the bolt through the fixed ear so that the bolt contacts the rim body. Rotating the bolt, in the threaded connection, fixes the bolt and locks the fixed ear, making the wheel core electromagnetic generator stable. Then, the end rod is released, allowing the elastic airbag to return to its original shape, pushing the limiting plate into the limiting groove to limit the bolt insertion and prevent the bolt from vibrating and loosening.

[0012] Preferably, a protective cover is slidably fitted onto the outer side of the bolt. The protective cover contacts the fixing lug, and an insert plate is fixedly connected to the protective cover. The insert plate is slidably connected to the fixing lug, and a metal spring is welded inside the fixing lug. A retaining ball is fixedly connected to the metal spring and is slidably connected to the insert plate. By pushing the protective cover onto the bolt, the protective cover contacts the fixing lug, and the insert plate is forcefully inserted into the fixing lug. During this process, when the end face of the insert plate contacts the retaining ball, the retaining ball moves under force and pushes the metal spring to deform, eventually causing the retaining ball to contact the surface of the insert plate. Under the action of force, the retaining ball slides along the surface of the insert plate. When the retaining ball slides into the retaining hole opened in the insert plate, the metal spring returns to its original deformation to push the retaining ball into the insert plate, limiting the insertion of the insert plate. This ensures that the insert plate and the protective cover are in a stable position, thereby protecting the bolt and preventing the overall structural strength from weakening due to corrosion of the bolt by water.

[0013] Preferably, multiple limiting grooves are provided, and the multiple limiting grooves are arranged in a circular array on the bolt. The setting of the limiting grooves facilitates the use of the limiting plate for snap-fit ​​connection.

[0014] Preferably, an elastic airbag is bonded to the skateboard, and the other end of the elastic airbag is bonded to the end rod. The end rod can be connected and used by means of the elastic airbag.

[0015] The beneficial effects of this invention are as follows: This invention relates to a power supply device for an intelligent tire internal sensor, which not only has the function of locking and fixing the wheel core electromagnetic generator to avoid the problem of vibration and loosening of the wheel core electromagnetic generator, but also has the feature of limiting the wires to avoid the problem of wire tangling. In specific use, compared with traditional intelligent tire internal sensor power supply devices, it has the following beneficial effects:

[0016] First, by setting up a limiting mechanism including a limiting cover, insert block, slot, guide rod, guide cylinder, spring, end plate, rubber pad, etc., the limiting cover is pushed into contact with the rim body, and the insert block is inserted into the rim body under force. Under the action of the spring, slot, etc., the insert block can be inserted and limited, so that the insert block drives the limiting cover to be in a stable position, thereby pressing and limiting the wire to avoid the problem of wire displacement and scattering.

[0017] Secondly, by setting up structures such as installation mechanism, fixing ears, bolts, limiting groove, end rod, limiting plate, sliding plate, elastic airbag, protective cover, and insert plate, the fixing ears can be locked by the bolts, thereby fixing the wheel core electromagnetic generator. Under the action of the limiting groove, limiting plate, elastic airbag and other structures, the bolt insertion can be limited to avoid the problem of bolt vibration and loosening. Under the action of the insert plate, locking ball and other structures, the protective cover can be limited, thereby protecting the bolt and avoiding the problem of bolt corrosion.

[0027] like Figure 1-7 As shown, the specific implementation adopts the following technical solution:

[0028] Example:

[0029] A smart tire internal sensor power supply device includes a rim body 1, a tire body 2, a sensor body 3, an energy storage device 4, a wheel core electromagnetic generator 5, a wire 6, a limiting mechanism 7, and a mounting mechanism 8. The tire body 2 is mounted on the rim body 1, the sensor body 3 is disposed inside the tire body 2, and the energy storage device 4 is disposed inside the tire body 2. The energy storage device 4 is electrically connected to the sensor body 3. The wheel core electromagnetic generator 5 is in contact with the rim body 1. The wheel core electromagnetic generator 5 and the energy storage device 4 are connected by a wire 6, which is in contact with both the tire body 2 and the rim body 1.

[0030] The wheel rim body 1 is provided with a limiting mechanism 7, which includes a limiting cover 71, a plug 72, a slot 73, a guide rod 74, a guide cylinder 75, a spring 76, an end plate 77, a rubber pad 78, a top plate 79, and a locking block 791. The limiting cover 71 contacts the wheel rim body 1 and is in contact with the wire 6. A plug 72 is fixedly connected to the limiting cover 71 and is slidably connected to the wheel rim body 1. Two plugs 72 are provided. Symmetrically distributed on the limiting cover 71, the limiting cover 71 can be installed and used through the setting of the insert block 72. The insert block 72 has a slot 73. A guide rod 74 is fixedly connected inside the rim body 1. A guide cylinder 75 is slidably sleeved on the outer side of the guide rod 74. A spring 76 is set on the outer side of the guide rod 74. One end of the spring 76 is welded to the guide cylinder 75, and the other end of the spring 76 is welded to the rim body 1. The guide cylinder 75 can be connected and used through the setting of the spring 76. An end plate 77 is slidably sleeved on the outer side of the rim 4. The end plate 77 is fixedly connected to the guide cylinder 75. A rubber pad 78 is adhered to the end plate 77. A top plate 79 is fixedly connected to the end plate 77 and slidably connected to the rim body 1. The top plate 79 contacts the insert block 72. A locking block 791 is fixedly connected to the top plate 79 and slidably connected to the locking groove 73. By pushing the rubber pad 78 away from the insert block 72, the end plate 77 is moved, and the end plate 77 is pushed by force. The guide tube 75 slides along the surface of the guide rod 74, the spring 76 deforms under force, and the end plate 77 is forced to move the top plate 79, which in turn moves the locking block 791. Then, the limiting cover 71 is pushed to contact the rim body 1, so that the rim body 1 contacts the wire 6, and the insertion block 72 is inserted into the rim body 1. Then, the end plate 77 is released so that the spring 76 returns to its original deformation, so as to push the locking block 791 into the slot 73, and the insertion block 72 is limited, so that the limiting cover 71 is in a stable position, avoiding the problem of the wire 6 being scattered.

[0031] The wheel rim body 1 and the wheel core electromagnetic generator 5 are both equipped with a mounting mechanism 8. The mounting mechanism 8 includes a fixing lug 81, a bolt 82, a limiting groove 83, an end rod 84, a limiting plate 85, a sliding plate 86, an elastic airbag 87, a protective cover 88, a insert plate 89, a metal spring 891, and a retaining ball 892. The wheel core electromagnetic generator 5 is fixedly connected to the fixing lug 81, and the bolt 82 is movably connected within the fixing lug 81. The bolt 82 is threadedly connected to the wheel rim body 1. Multiple limiting grooves 83 are provided within the bolt 82, arranged in a circular array on the bolt 82. The limiting grooves 83 facilitate engagement with the limiting plate 85. An end rod 84 is slidably connected inside the fixed ear 81. A limiting plate 85 is fixedly connected to the end rod 84. The limiting plate 85 is slidably connected to the fixed ear 81 and to the limiting groove 83. A sliding plate 86 is fixedly connected inside the fixed ear 81. The sliding plate 86 is slidably connected to the end rod 84. An elastic airbag 87 is adhered to the sliding plate 86. The other end of the elastic airbag 87 is adhered to the end rod 84. The end rod 84 can be connected and used through the setting of the elastic airbag 87. A protective cover 88 is slidably sleeved on the outside of the bolt 82. The protective cover 88 contacts the fixed ear 81. An insert plate 89 is fixedly connected to the protective cover 88. The insert plate 89 is slidably connected to the fixed ear 81. The fixed ear 81 is welded with... A metal spring 891 is provided, and a retaining ball 892 is fixedly connected to the metal spring 891. The retaining ball 892 is slidably connected to the insert plate 89. By pulling the end rod 84 away from the fixed ear 81, the end rod 84 slides along the surface of the slide plate 86, causing the elastic airbag 87 to deform under force. The end rod 84, under force, drives the limiting plate 85 to move, and then pushes the bolt 82 through the fixed ear 81, so that the bolt 82 contacts the rim body 1. Rotating the bolt 82, under the threaded connection, fixes the bolt 82, thereby locking the fixed ear 81, so that the wheel core electromagnetic generator 5 is in a stable position. Then, the end rod 84 is released, so that the elastic airbag 87 returns to its deformation, pushing the limiting plate 85 into the limiting groove 83, and inserting the bolt 82. To limit the movement and prevent the bolt 82 from loosening due to vibration, the protective cover 88 is pushed onto the bolt 82, causing it to contact the fixing lug 81. The insert plate 89 is then inserted into the fixing lug 81. During this process, when the end face of the insert plate 89 contacts the retaining ball 892, the retaining ball 892 moves under force, causing the metal spring 891 to deform. Ultimately, the retaining ball 892 contacts the surface of the insert plate 89. Under the action of force, the retaining ball 892 slides along the surface of the insert plate 89. When the retaining ball 892 slides into the retaining hole in the insert plate 89, the metal spring 891 returns to its original shape, pushing the retaining ball 892 into the insert plate 89. This limits the insertion of the insert plate 89, ensuring the protective cover 88 is stably positioned and thus protecting the bolt 82.To prevent the overall structural strength from weakening due to corrosion of bolt 82 by water.

[0032] The invention is used as follows: When in use, by pulling the end rod 84 away from the fixed ear 81, the end rod 84 slides along the surface of the slide plate 86, the elastic airbag 87 deforms under force, and the end rod 84 moves the limiting plate 85 under force, then pushes the bolt 82 through the fixed ear 81, so that the bolt 82 contacts the rim body 1, rotates the bolt 82, and fixes the bolt 82 under the threaded connection, thereby locking the fixed ear 81, so that the wheel core electromagnetic generator 5 is in a stable position, and then the end rod 84 is released to allow the elastic airbag 87 to recover its deformation, so as to push the limiting plate 85 into the limiting groove 83, and limit the insertion of the bolt 82 to avoid the problem of the bolt 82 vibrating and loosening.

[0033] By pushing the protective cover 88 onto the bolt 82, the protective cover 88 comes into contact with the fixing ear 81, and the insert plate 89 is inserted into the fixing ear 81 under force. During this process, when the end face of the insert plate 89 comes into contact with the retaining ball 892, the retaining ball 892 moves under force and pushes the metal spring 891 to deform, eventually making the retaining ball 892 contact the surface of the insert plate 89. Under the action of force, the retaining ball 892 slides along the surface of the insert plate 89. When the retaining ball 892 slides into the retaining hole opened in the insert plate 89, the metal spring 891 restores its deformation to push the retaining ball 892 into the insert plate 89, thereby limiting the insertion of the insert plate 89 and making the insert plate 89 drive the protective cover 88 to be in a stable position, thus protecting the bolt 82 and preventing the bolt 82 from being corroded by water, which would weaken the overall structural strength.

[0034] By pushing the rubber pad 78 to move away from the insert block 72, the end plate 77 is moved. The end plate 77 is forced to push the guide cylinder 75 to slide along the surface of the guide rod 74. The spring 76 is deformed by force, and the end plate 77 can move the top plate 79, which in turn moves the locking block 791. Then, the limiting cover 71 is pushed to contact the rim body 1, so that the rim body 1 contacts the wire 6, and the insert block 72 is inserted into the rim body 1. Then, the end plate 77 is released so that the spring 76 returns to its deformation, so that the locking block 791 is inserted into the slot 73, and the insert block 72 is limited, so that the limiting cover 71 is in a stable position, avoiding the problem of the wire 6 being scattered.

[0035] During vehicle operation, as tire speed increases, the wheel-core electromagnetic generator 5 supplies power by cutting magnetic field lines. Through the power management module and rechargeable button battery inside the energy storage device 4, when the vehicle is running at high speed, the wheel-core electromagnetic generator 5 can supply power to the sensor body 3 and charge the energy storage module. After being fully charged, it automatically cuts off the power. At low speeds, it supplies power to the sensor body 3. The power management module in the energy storage device 4 includes an AC to DC conversion module and a sleep / wake-up management module. The sleep / wake-up management module means that when the vehicle is stationary, the sensor body 3 enters an ultra-low power sleep mode, and when the vehicle leaves the stationary state, the sensor body 3 is woken up and enters normal working state.
