Description

Technical Field

[0001] This invention belongs to the field of inflation device technology, specifically an intelligent inflation device for rubber tires of straddle-type vehicles. Background Technology

[0002] A straddle-type monorail transit system is a rail transit system that uses a single track for support, stability, and guidance, with the vehicle straddling the track beam. Straddle-type monorail vehicles travel on independently constructed monorail bridges. In addition to the running wheels, the vehicle's bogie design incorporates guide wheels and stabilizing wheels at both ends, encircling the track. This design allows the vehicle to travel stably along the track and provides strong terrain adaptability.

[0003] Chinese patent application CN201810381275.2 discloses an intelligent inflation device for rubber tires of straddle-type monorail vehicles, including an inflation mechanism and an explosion-proof frame. The side plates of the frame are equipped with a toothed ring and a circular slide rail. The inflation mechanism includes a rotating platform and an air nozzle. The inner sides of the bottom two side plates of the rotating platform are equipped with sliders and large gears. The sliders engage with the circular slide rails, and the large gears mesh with the toothed ring. The rotating platform is equipped with a telescopic platform and a telescopic motor. The bottom of the telescopic motor is equipped with a small gear. An air supply pipe is located on one side of the telescopic motor and is connected to the air nozzle. A rack is provided along the air supply direction in the air supply pipe, and the rack meshes with the small gear.

[0004] In the aforementioned patent, straddle-type vehicle tires are inflated directly using an air pump during maintenance and inflation. Since straddle-type vehicles operate at high speeds for extended periods, their rubber tires are prone to aging and bulging. Furthermore, the lack of proper protective measures during maintenance and inflation greatly increases the risk of overinflation, leading to tire bursts and injuries. Moreover, tire wear is inevitable after prolonged use, and problems are often only discovered and corrected during maintenance, which is time-consuming and inefficient.

[0005] Therefore, the present invention provides an intelligent inflation device for rubber tires of straddle-type vehicles. Summary of the Invention

The bottom of each sliding rod is hemispherical, and a backing plate is fixedly installed at the top of the slide plate. Two scales are fixedly installed at the top of the backing plate. The output end of the electric push rod is connected to the slide plate via a connector. The protective frame also includes a clamping mechanism for positioning the tire body and an air blowing mechanism for cleaning the tire.

[0008] Furthermore, the connector is composed of several slidably connected round rods. One end of the connector is locked to the output end of the electric push rod by a screw, and the other end of the connector is fixedly connected to the slide plate.

[0009] Furthermore, an arc-shaped scraper is fixedly installed on the surface of the sliding rod.

[0010] Furthermore, the clamping mechanism includes two clamping plates symmetrically arranged within the protective frame. The clamping plates are slidably connected to the protective frame via a sliding rod. A spring is fixedly installed between the protective frame and the clamping plates. Several placement slots are provided on the side of the two clamping plates that are close to each other, and rotating balls are wedged in the placement slots.

[0011] Furthermore, a sliding push plate is connected to the placement groove by a spring, and one side of the push plate abuts against the rotating ball.

[0012] Furthermore, an arc-shaped guide plate is fixedly installed at one end of the clamping plate, and a number of guide posts are rotatably connected to one side of the guide plate.

[0013] Furthermore, the air blowing mechanism includes a rectangular groove at the top of the protective frame, a hollow elastic block made of rubber is fixedly installed inside the rectangular groove, a first chamber is opened inside the elastic block, an air outlet pipe connected to the first chamber is fixedly installed inside the protective frame, and the slider is located in the placement groove and abuts against the elastic block.

[0014] Furthermore, the elastic block is provided with a second chamber, which is pre-stored with maintenance fluid. A liquid guide tube connected to the interior of the second chamber is fixedly installed at the bottom of the elastic block. A connecting pipe is fixedly installed on one side of the slide plate. The end of the liquid guide tube away from the elastic block is connected to the interior of the liquid guide tube. An outlet hole is opened at the bottom of the connecting pipe.

[0015] Furthermore, a marking spraying mechanism is provided inside the protective frame. The spraying mechanism includes a rubber box fixedly installed inside the protective frame, and a spray pipe is fixedly installed at the bottom of the rubber box. The rubber box and the connecting pipe are on the same plane.

[0016] Furthermore, the slider has arc-shaped sides and rounded corners at the top.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The present invention discloses an intelligent tire inflation device for straddle-type vehicles. The disassembled tire body is dragged into a protective frame, and a servo motor rotates the tire body via a second rolling column, aligning the tire's valve, inflation hose, and extension hose in a straight line. An air pump inflates the tire body through the inflation hose and extension hose, and the inflation is observed through a glass window in the protective frame. Because the tire body is mounted on a straddle-type vehicle, and due to the high speed and prolonged contact and friction between the tire and the track, the wear and tear on the tire body is greater than on other vehicles. The tire body is prone to uneven wear and bulges. A bulging tire body is susceptible to explosion during inflation. Therefore, the above-designed structure provides protection during tire inflation, ensuring efficient inflation while protecting the operator, and allowing real-time monitoring of the tire's inflation status.

[0019] 2. The intelligent tire inflation device for straddle-type vehicles described in this invention allows for the detection of the tire's wear by observing whether the top of the sliding rod is on the same plane as the scale on the back plate. Since the tire body has grooves, two scales are designed on the back plate to detect the sliding rod within the grooves. When the top of the sliding rod is within the scale range, it indicates that the tire wear is within the normal range. When the sliding rod is below the scale, it indicates that the tire body is excessively worn, indicating uneven wear, and the tire body needs to be replaced promptly to avoid safety hazards. When the servo motor rotates the tire body via the second rolling column, the sliding rod contacts the entire surface of the tire body, thus achieving full tire detection. When the electric push rod moves, it moves the sliding rod and the slide plate together via the connecting piece, thereby comprehensively detecting wider tires and preventing situations where wider tires are difficult to detect with the sliding rod on the slide plate.

[0020] 3. The intelligent tire inflation device for straddle-type vehicles described in this invention uses the arc-shaped surface at the top of the slider to compress the first chamber of the elastic block, causing the gas in the first chamber to be sprayed onto the tire body through the air outlet pipe, thereby cooling the tire body and preventing the temperature of the tire body itself from affecting the tire pressure monitoring judgment. If the test shows a failure, the slide plate continues to move, and the end of the connecting pipe on one side of the slide plate is used to compress the rubber box, causing the pre-stored coating in the rubber box to be sprayed onto the surface of the tire body through the spray pipe, thereby marking the tire body and prompting the staff that the tire body has uneven wear and needs to be replaced and repaired in time. When the tire body is found to be a qualified product, one end of the slider is used to compress the second chamber in the elastic block, allowing the maintenance fluid in the second chamber to enter the connecting pipe through the flexible liquid guide pipe, and then be sprayed onto the surface of the tire body through the liquid outlet at the bottom of the connecting pipe, performing maintenance work on the tire body.

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] like Figures 1 to 10As shown in the figure, an intelligent tire inflation device for straddle-type vehicles according to an embodiment of the present invention includes a protective frame 1, a plurality of glass windows 3 installed on the surface of the protective frame 1, and a tire body 2 provided on one side of the protective frame 1; an inflation mechanism 10 for protecting the tire body 2 during inflation is provided on one side of the protective frame 1, the inflation mechanism 10 includes a groove 11 opened in the protective frame 1, two symmetrically arranged first rolling columns 12 and a second rolling column 13 are rotatably connected inside the groove 11, a servo motor 14, an air pump 15 and an electric push rod 17 are fixedly installed on one side of the protective frame 1, the electric push rod 17 is fastened by screws, the output end of the servo motor 14 is fixedly connected to the second rolling column 13, an inflation tube 16 is fixedly installed on one side of the air pump 15, the end of the inflation tube 16 away from the air pump 15 is slidably connected to the protective frame 1 and is inside the protective frame 1, the output end of the electric push rod 17 is inside the protective frame 1, an extension tube 18 is fixedly installed on the end of the inflation tube 16 away from the air pump 15, and the output end of the electric push rod 17 is fixedly connected to the extension tube 18;

[0042] During operation, the disassembled tire body 2 is dragged into the protective frame 1, positioning it between the two first rolling columns 12 and in contact with their surfaces, with the bottom of the tire body 2 in contact with the surface of the second rolling column 13. The servo motor 14 is then activated, causing it to rotate the tire body 2 via the second rolling column 13, aligning the tire body 2's valve, inflation tube 16, and extension tube 18 in a straight line. Positioning is achieved using a vision sensor (specifically a Panasonic EX-L211 laser sensor; a suitable sensor model can be used depending on the specific situation). The valve cap on the tire body 2 is removed before it enters the protective frame 1. Then, the electric push rod 17 on one side of the protective frame 1 is activated, moving the extension tube 18 and inflation tube 16 towards the tire body 2, aligning them with the valve. At this point, the air pump 15 on one side of the protective frame 1 is activated, allowing the air pump 15 to inflate the tire body 2 through the air inflator 16 and extension tube 18. Simultaneously, the display on the tire body 2 shows the tire pressure. When the appropriate pressure is reached, the air pump 15 will automatically stop inflating. The inflation of the tire body 2 can be observed through the glass window 3 on the protective frame 1. Because the tire body 2 is installed on a straddle-type vehicle, and due to the high speed of the straddle-type vehicle and the prolonged contact and friction between the tire and the track, the wear and tear on the tire body 2 is greater than that on other vehicles. The tire body 2 is prone to uneven wear and bulges. A bulging tire body 2 is prone to explosion during inflation. Therefore, the structure designed above can protect the tire body 2 during inflation, ensuring efficient inflation while protecting the personnel, and allowing real-time observation of the tire body 2's inflation status.

[0043] The protective frame 1 is equipped with a detection mechanism 20 for detecting the tire body 2. The detection mechanism 20 includes a slider 21 that slides within the protective frame 1. A slide plate 22 is fixedly installed at the bottom of the slider 21. Several sliding rods 23 are slidably connected within the slide plate 22. The bottom of the sliding rods 23 is hemispherical. A backing plate 24 is fixedly installed at the top of the slide plate 22. Two scales 25 are fixedly installed at the top of the backing plate 24.

[0044] Specifically, the output end of the electric push rod 17 and the slide plate 22 are connected by a connector 19. The connector 19 is composed of several slidably connected round rods. One end of the connector 19 is locked to the output end of the electric push rod 17 by a screw, and the other end of the connector 19 is fixedly connected to the slide plate 22. An arc-shaped scraper 50 is fixedly installed on the surface of the sliding rod 23.

[0045] During operation, when the tire body 2 enters the protective frame 1, the sliding rod 23 on the slide plate 22 will slide up and down before contacting the surface of the tire body 2. By using the bottom of the sliding rod 23 to contact the surface of the tire body 2, observe whether the top of the sliding rod 23 is on the same plane as the scale 25 on the back plate 24 (meaning the top of the sliding rod 23 is within the width of the scale 25). Since the tire body 2 has a groove 11, two scales 25 are designed on the back plate 24 to detect the sliding rod 23 in the groove 11. The arc-shaped scraper 50 installed on the surface of the sliding rod 23 helps to remove impurities in the groove 11 of the tire body 2, reducing the impact on the detection results. When the top of the sliding rod 23 is within the width range of the scale 25, it indicates that the wear of the tire body 2 is within the normal range (regardless of whether the bottom of the sliding rod 23 is located on the tire tread or in the groove of the anti-slip pattern on its surface, the sliding rod 23 located on the tread is referenced to the higher scale 25, and the sliding rod 23 located in the groove is referenced to the lower scale 25). When one or more of the sliding rods 23 are below or nearly flush with the lowest end face of the higher scale 25 (at this time, it should be considered that the sliding rod 23 is in contact with the tire tread), it indicates that the tire body 2 is excessively worn, which is considered uneven wear, and the tire body 2 needs to be replaced in time to avoid safety hazards. When the servo motor 14 rotates the tire body 2 through the second rolling column 13 (at this time, it rotates at a low speed), the sliding rod 23 will contact the entire surface of the tire body 2, thereby realizing the detection of the entire tire. When the electric push rod 17 moves, it moves along with the slide plate 22 and sliding rod 23 via the connector 19, thus enabling comprehensive inspection of wider tire bodies 2. This avoids situations where wider tires might be difficult for the sliding rod 23 on the slide plate 22 to detect. Since tire sizes vary, the electric push rod 17, secured by screws, can be adjusted vertically along with the inflation tube 16 and extension tube 18 to accommodate different tire body sizes 2. The connector 19, secured to the output end of the electric push rod 17 by screws, can also slide and stretch to adjust the position of the electric push rod 17. This design achieves simple and efficient tire wear testing 2 while effectively reducing costs, making it easy to promote and use.

[0046] The protective frame 1 is also provided with a clamping mechanism 30 for positioning the tire body 2. The clamping mechanism 30 includes two clamping plates 31 symmetrically arranged in the protective frame 1. The clamping plates 31 are slidably connected to the protective frame 1 through a slide rod 70. A spring is fixedly installed between the protective frame 1 and the clamping plates 31. Several placement slots 32 are opened on the side of the two clamping plates 31 that are close to each other. A rotating ball 34 is wedged in the placement slot 32.

[0047] Specifically, a sliding push plate 33 is connected to the placement groove 32 by a spring. One side of the push plate 33 abuts against the rotating ball 34. An arc-shaped guide plate 35 is fixedly installed at one end of the clamping plate 31. Several guide posts 36 are rotatably connected to one side of the guide plate 35.

[0048] During operation, when the tire body 2 enters the protective frame 1, it first contacts the arc-shaped guide plate 35 and the guide post 36 on its surface. The guide post 36 and guide plate 35 push the two clamping plates 31 away from each other. The clamping plates 31 move within the protective frame 1 via the slide rod 70, while the two clamping plates 31 are constantly moving towards each other due to the force of the springs. When the tire body 2 enters between the two clamping plates 31, the side of the tire body 2 contacts the rotating ball 34 in the placement groove 32. Because the rotating ball 34 is acted upon by the spring of the push plate 33, the push plate 33 always keeps the rotating ball 34 in contact with the surface of the tire body 2. Therefore, when the second rolling column 13 rotates the tire body 2, the rotating ball 34 will rotate in tandem with the tire body 2, thus preventing the two clamping plates 31 from clamping the tire body 2 and preventing it from rotating. This design achieves positioning of the tire body 2 without hindering its normal rotation.

[0049] The protective frame 1 is equipped with an air blowing mechanism 40 for cleaning tires. The air blowing mechanism 40 includes a rectangular groove 41 at the top of the protective frame 1. A hollow elastic block 42 made of rubber is fixedly installed inside the rectangular groove 41. The elastic block 42 has a first chamber 43 inside. An air outlet pipe 44 connected to the first chamber 43 is fixedly installed inside the protective frame 1. The slider 21 is located in the placement groove 32 and abuts against the elastic block 42. The sides of the slider 21 are arc-shaped and the top has rounded corners. The elastic block 42 has a second chamber 45. The second chamber 45 is pre-stored with maintenance fluid. A liquid guide pipe 46 connected to the inside of the second chamber 45 is fixedly installed at the bottom of the elastic block 42. A connecting pipe 47 is fixedly installed on one side of the slide plate 22. The end of the liquid guide pipe 46 away from the elastic block 42 is connected to the inside of the liquid guide pipe 46. An outlet hole is opened at the bottom of the connecting pipe 47.

[0050] Specifically, a marking spraying mechanism 60 is provided inside the protective frame 1. The spraying mechanism 60 includes a rubber box 61 fixedly installed inside the protective frame 1. A spray pipe 62 is fixedly installed at the bottom of the rubber box 61. The rubber box 61 and the connecting pipe 47 are on the same plane.

[0051] During operation, when the slide plate 22 slides in the groove of the protective frame 1 through the slider 21, the arc-shaped surface at the top of the slider 21 will squeeze the first chamber 43 of the elastic block 42, causing the gas in the first chamber 43 to be sprayed onto the tire body 2 through the exhaust pipe 44, thereby cooling the tire body 2 and preventing the tire body 2 from being affected by its own temperature, thus avoiding the judgment of tire pressure monitoring.

[0052] After the slide plate 22 moves and completes the inspection of the tire body 2, if the inspection fails, the slide plate 22 continues to move. The end of the connecting pipe 47 on one side of the slide plate 22 is used to squeeze the rubber box 61, so that the paint pre-stored in the rubber box 61 is sprayed onto the surface of the tire body 2 through the spray pipe 62, thereby marking the tire body 2 and prompting the staff that the tire body 2 has uneven wear and needs to be replaced and repaired in time.

[0053] When the sliding rod 23 on the slide plate 22 has completed the inspection of the tire body 2 and found it to be a qualified product, and the tire has been inflated, the electric push rod 17 will separate from the valve of the tire body 2 along with the extension tube 18 and the inflation tube 16. At this time, the slide plate 22 will move accordingly. After the slide plate 22 moves to the initial position, it will continue to move away from the tire body 2, so that one end of the slider 21 squeezes the second chamber 45 in the elastic block 42, allowing the maintenance fluid in the second chamber 45 to enter the connecting tube 47 through the flexible liquid guide tube 46, and spray onto the surface of the tire body 2 through the liquid outlet at the bottom of the connecting tube 47 to perform maintenance on the tire body 2.

[0054] Working principle: By dragging the disassembled tire body 2 into the protective frame 1, it will first contact the arc-shaped guide plate 35 and the guide post 36 on its surface. The guide post 36 and the guide plate 35 will push the two clamping plates 31 away from each other. The clamping plates 31 move within the protective frame 1 via the slide rod 70. At the same time, the two clamping plates 31 are constantly moving towards each other due to the force of the spring. When the tire body 2 enters between the two clamping plates 31, the side of the tire body 2 contacts the rotating ball 34 in the placement groove 32. Due to the spring action of the push plate 33, the push plate 33 always keeps the rotating ball 34 in contact with the surface of the tire body 2. At this time, the tire body 2 is between the two first rolling posts 12 and in contact with the surface, and the bottom of the tire body 2 is in contact with the surface of the second rolling post 13. The servo motor 14 is activated, causing the tire body 2 to rotate via the second rolling column 13. This aligns the valve on the tire body 2 with the inflation hose 16 and extension hose 18, using a visual sensor for positioning. The valve cap on the tire body 2 is removed before it enters the protective frame 1. Next, the electric push rod 17 on one side of the protective frame 1 is activated, moving the extension hose 18 and inflation hose 16 towards the tire body 2, aligning them with the valve on the tire body 2. Then, the air pump 15 on one side of the protective frame 1 is activated, inflating the tire body 2 through the inflation hose 16 and extension hose 18. The tire pressure is displayed on the tire body 2's screen. The air pump 15 automatically stops inflating when the appropriate pressure is reached. The inflation process can be observed through the glass window 3 on the protective frame 1.

[0055] When the tire body 2 enters the protective frame 1, the sliding rod 23 on the slide plate 22 slides up and down before contacting the surface of the tire body 2. By using the bottom of the sliding rod 23 to contact the surface of the tire body 2, it is observed whether the top of the sliding rod 23 is on the same plane as the scale 25 on the back plate 24. Since the tire body 2 has a groove 11, two scales 25 are designed on the back plate 24 to detect the sliding rod 23 in the groove 11. The arc-shaped scraper 50 installed on the surface of the sliding rod 23 helps to remove impurities in the groove 11 of the tire body 2. When the servo motor 14 rotates the tire body 2 through the second rolling column 13, the sliding rod 23 will contact the entire surface of the tire body 2, thereby realizing the detection of the entire tire.

[0056] When the slide plate 22 slides within the groove of the protective frame 1 via the slider 21, the arc-shaped surface at the top of the slider 21 compresses the first chamber 43 of the elastic block 42, causing the gas in the first chamber 43 to be sprayed onto the tire body 2 through the exhaust pipe 44, thereby cooling the tire body 2. After the slide plate 22 has completed its inspection of the tire body 2, if the inspection fails, the slide plate 22 continues to move, and the end of the connecting pipe 47 on one side of the slide plate 22 is used to compress the rubber box 61, causing the pre-stored coating in the rubber box 61 to be sprayed onto the surface of the tire body 2 through the spray pipe 62. When the sliding rod 23 on the slide plate 22 has completed the inspection of the tire body 2 and found it to be a qualified product, the electric push rod 17 will separate from the air valve of the tire body 2 along with the extension tube 18 and the inflation tube 16. At this time, the slide plate 22 will move accordingly. After the slide plate 22 moves to the initial position, it will continue to move away from the tire body 2, so that one end of the slider 21 squeezes the second chamber 45 in the elastic block 42, allowing the maintenance fluid in the second chamber 45 to enter the connecting tube 47 through the flexible liquid guide tube 46, and be sprayed onto the surface of the tire body 2 through the liquid outlet at the bottom of the connecting tube 47.
