[0001] The utility model relates to the technical field of tire pressure monitoring, in particular to a Bluetooth tire pressure monitoring device. Background Technique

[0002] Tire pressure, strictly speaking, refers to the air pressure inside the tire. In vehicle maintenance, the engine is the heart of the vehicle, and the damage of the engine will lead to the exhaustion of the vehicle's life. Then the tire pressure is the blood pressure of the vehicle, and the level of tire pressure plays a crucial role in the performance and power of the vehicle.

[0003] For example, in the "Tire Pressure Monitoring Device for Inflatable Tires" with the Chinese patent publication number CN216231508U, this utility model discloses a tire pressure monitoring device for inflatable tires, which relates to the field of electric vehicles. The key points of its technical solution include a fastening cylinder; a pneumatic rod carried in the fastening cylinder, with a driving sealing part arranged on the pneumatic rod; a monitoring housing, an elastic resetting part is arranged between the monitoring housing and the pneumatic rod, and a positioning ring is arranged in the fastening cylinder; a deflation push head carried on the positioning ring; a sealing gasket carried in the fastening cylinder; a tire pressure monitoring component carried in the monitoring housing; wherein, when the tire pressure is normal, the pressure difference on both sides of the driving sealing part causes the pneumatic rod to be pushed to contact the tire pressure monitoring component, so that the tire pressure monitoring component is powered on and works, and at this time the elastic resetting part is in a compressed state; when the tire pressure is insufficient, the elastic resetting part releases elastic force, pushes the pneumatic rod to separate from the tire pressure monitoring component, so that the tire pressure monitoring component is powered off and does not work. This utility model can simplify the structure and process, reduce costs, and can also reduce power consumption and extend the service life.

[0004] However, in actual use, it has the problem of being inconvenient to fasten on the wheel rim. It is installed on the valve on the wheel rim through a threaded fastening cylinder. When the wheel moves, it is easy to become loose, resulting in tire deflation and being inconvenient for accurate pressure measurement. Therefore, a Bluetooth tire pressure monitoring device is proposed to solve the above-mentioned problems. Content of the Utility Model

[0005] The technical problem to be solved by this utility model is to provide a Bluetooth tire pressure monitoring device aiming at the deficiencies in the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a Bluetooth tire pressure monitoring device, including an air guide chamber, a mounting sleeve is fixedly connected to the bottom of the air guide chamber, a pressure measuring assembly is arranged above the air guide chamber, an air intake chamber is fixedly connected to the left side of the air guide chamber, a supporting device is arranged on the outer surface of the air intake chamber, the supporting device includes a supporting plate, the supporting plate is fixedly connected to the outer surface of the air intake chamber, a screw is rotatably connected to the top of the supporting plate, a lifting frame is arranged on the threaded sleeve on the outer surface of the screw, and a lifting frame is fixedly connected to the inner surface of the lifting frame There are two sliding bars, and the sliding bars are slidably connected to the front and back sides of the support plate. A sealing component is arranged on the left side of the lifting frame, and a fixing component is arranged under the lifting frame. The mounting sleeve is installed on the air nozzle in the wheel rim. When the mounting sleeve is installed, the air guide chamber will be connected with the tire. At this time, the tire can be inflated through the air intake chamber. After the mounting sleeve is installed, the lifting frame is lowered on the support plate by rotating the screw rod. The lifting frame will drive the connecting block and the connecting bar to make the suction cup on the movable bar contact and adsorb the inner surface of the wheel rim.

[0007] Preferably, the fixing assembly comprises a connecting block, the connecting block is fixedly connected to the lower part of the lifting frame, a connecting strip is fixedly connected to the lower part of the connecting block, and suction cup assemblies are arranged at the front and rear ends of the connecting strip.

[0008] Preferably, the suction cup assembly includes a movable bar, which is hinged to a connecting bar, a suction cup is fixedly connected to the bottom of the movable bar, an elastic sheet is fixedly connected to the top of the movable bar, and the elastic sheet is movably fitted with the bottom of the lifting frame. As the suction cup contacts the wheel rim, the movable bar will hinge and under the action of the elastic sheet, the suction cup will always press against the inner surface of the wheel rim, so as to facilitate adaptation to the curvature of the inner surface of the wheel rim. At this time, the suction cup adsorbs the inner surface of the wheel rim, so that the mounting sleeve cannot rotate on the air nozzle inside the wheel rim, thereby achieving the effect of tightening the installation.

[0009] Preferably, the number of the suction cup assemblies is two groups, and the two groups of suction cup assemblies are symmetrically arranged at the front and rear ends of the connecting strip respectively.

As the lifting frame descends on the support plate, it will drive the plug plate to descend, and the plug plate will be inserted between the two fixing strips, so that the sealing cover cannot rotate on the air intake bin. At this time, the sealing cover will firmly close the air intake bin, so as to make the air guide bin airtight. At this time, the pressure in the air guide bin is the same as the pressure in the tire.

[0011] Preferably, the pressure measuring assembly includes a sensing head, which penetrates and is fixedly connected to the upper part of the air guide chamber. A tire pressure detector is fixedly installed above the sensing head, and a Bluetooth component is fixedly installed on the front of the tire pressure detector.

[0014] 2. For this Bluetooth tire pressure monitoring device, when the pressing device presses downward, it drives the insertion plate to descend and insert between the two fixing strips on the sealing cover, preventing the sealing cover from loosening on the air inlet chamber and ensuring the sealing effect.

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0020] Please refer to Figures 1 - 3 For an embodiment of the present utility model: A Bluetooth tire pressure monitoring device includes an air guide chamber 1. A mounting sleeve 2 is fixedly connected below the air guide chamber 1. The mounting sleeve 2 is used to be mounted on the air nozzle inside the wheel rim. The inner surface of the mounting sleeve 2 is provided with threads adapted to the air nozzle. When the mounting sleeve 2 is installed, the air guide chamber 1 will communicate with the inside of the tire. A pressure measuring component 3 is provided above the air guide chamber 1. An air inlet chamber 4 is fixedly connected to the left side of the air guide chamber 1. Through the air inlet chamber 4, air can be added to the air nozzle inside the wheel rim to achieve the function of inflating the tire. The air inlet chamber 4 is communicated with the air guide chamber 1. A holding device 5 is provided on the outer surface of the air inlet chamber 4. The holding device 5 includes a support plate 501. The support plate 501 is fixedly connected to the outer surface of the air inlet chamber 4. A screw rod 502 is rotatably connected above the support plate 501. A lifting frame 503 is threadedly sleeved on the outer surface of the screw rod 502. The lifting frame 503 is in a square frame shape, and its inner surface is movably attached to the front and back surfaces of the support plate 501. A sliding bar 504 is fixedly connected to the inner surface of the lifting frame 503. The number of sliding bars 504 is two. The sliding bars 504 are slidably connected to the front and back surfaces of the support plate 501. Sliding grooves adapted to the sliding bars 504 are opened on the front and back surfaces of the support plate 501. A sealing component 6 is provided on the left side of the lifting frame 503. A fixing component 7 is provided below the lifting frame 503. The fixing component 7 includes a connecting block 701. The connecting block 701 is fixedly connected to the lower part of the lifting frame 503. A connecting strip 702 is fixedly connected below the connecting block 701. Suction cup components 8 are provided at the front and rear ends of the connecting strip 702. The number of suction cup components 8 is two groups. The two groups of suction cup components 8 are symmetrically arranged at the front and rear ends of the connecting strip 702 respectively. The suction cup component 8 includes a movable strip 801. The movable strip 801 is hinged to the connecting strip 702. A suction cup 802 is fixedly connected below the movable strip 801. An elastic piece 803 is fixedly connected above the movable strip 801. The elastic piece 803 is movably attached to the lower part of the lifting frame 503. The suction cup component 8 can adapt to the curvature inside the wheel rim and has a better fixing effect.

[0021] Working principle: When in use, first install the mounting sleeve 2 on the air nozzle inside the wheel rim. When the mounting sleeve 2 is installed, the air guide chamber 1 will communicate with the inside of the tire. At this time, the tire can be inflated through the air inlet chamber 4. After the mounting sleeve 2 is installed, rotate the screw rod 502 to make the lifting frame 503 descend on the support plate 501. The lifting frame 503 will drive the connecting block 701 and the connecting strip 702, so that the suction cup 802 on the movable strip 801 contacts and adsorbs the inner surface of the wheel rim. As the suction cup 802 contacts the wheel rim, the movable strip 801 will move in a hinge motion and under the action of the elastic piece 803, the suction cup 802 will always press against the inner surface of the wheel rim, achieving the function of facilitating adaptation to the curvature of the inner surface of the wheel rim. At this time, the suction cup 802 adsorbs the inner surface of the wheel rim, making the mounting sleeve 2 unable to rotate on the air nozzle inside the wheel rim, achieving the function of firm installation.

[0022] Please refer to Figures 1 - 3 , based on the above embodiments, in another embodiment of the present utility model, the sealing assembly 6 includes a sealing cover 601. The sealing cover 601 is threadedly connected to the left side of the air inlet chamber 4. The sealing cover 601 is used to seal the air inlet chamber 4. A fixing strip 602 is fixedly connected to the outer surface of the sealing cover 601. The fixing strips 602 are annularly distributed on the outer surface of the sealing cover 601. An insertion plate 603 is arranged above the fixing strip 602. The insertion plate 603 is used to be inserted between two fixing strips 602 to prevent the sealing cover 601 from rotating. The insertion plate 603 is fixedly connected to the left side of the lifting frame 503. The pressure measuring assembly 3 includes a sensing head 301. The sensing head 301 is used to sense the pressure in the air guiding chamber 1. The sensing head 301 penetrates and is fixedly connected to the upper part of the air guiding chamber 1. A tire pressure detector 302 is fixedly installed above the sensing head 301. The tire pressure detector 302 is used to read the tire pressure in the air guiding chamber 1 through the sensing head 301. A Bluetooth component 303 is fixedly installed on the front of the tire pressure detector 302. The Bluetooth component 303 is used to transmit the reading detected by the tire pressure detector 302 to the in-vehicle Bluetooth device, facilitating the reading of the tire pressure in the vehicle.

[0023] Working principle: As the lifting frame 503 descends on the support plate 501, it will drive the insertion plate 603 to descend. The insertion plate 603 will be inserted between two fixing strips 602, preventing the sealing cover 601 from rotating on the air inlet chamber 4. At this time, the sealing cover 601 will firmly seal the air inlet chamber 4, achieving the effect of sealing the air guiding chamber 1. At this time, the pressure in the air guiding chamber 1 is the same as the pressure in the tire. The pressure in the air guiding chamber 1 will be detected by the sensing head 301 and then transmitted to the tire pressure detector 302 to read the tire pressure in the air guiding chamber 1. The read tire pressure will be transmitted to the in-vehicle Bluetooth device through the Bluetooth component 303, achieving the effect of facilitating the reading of the tire pressure in the vehicle.
