Description

Technical Field

[0001] This utility model relates to the field of automotive oil pipe technology, specifically to a pipe clamp for automotive oil pipes. Background Technology

[0002] Pipe clamps play a crucial role in the installation and securing of automotive fuel lines. Common automotive fuel line clamps are mostly made of metal, such as stainless steel or aluminum alloy. Their basic structure typically consists of two opposing, curved clamping plates and a connecting bolt. The clamping plates have a certain curvature to conform to the outer wall of the fuel line. By tightening the bolt, the clamping plates exert radial pressure on the fuel line, thus stably fixing it to the vehicle chassis or other designated location. This structure is simple and low-cost, and is widely used in the automotive manufacturing industry. Furthermore, some pipe clamps have been optimized in appearance, such as adopting streamlined designs to reduce wind resistance or improve aesthetics, thus meeting the requirements of overall automotive design to a certain extent. However, the existing technology has the following problems:

[0003] Existing automotive oil pipe clamps lack pressure-adaptive clamp components. Under the complex operating environment of automobiles, the clamping force of the clamps on the oil pipes cannot be automatically adjusted in real time. When the vehicle frequently experiences vibration and impact, the clamps may fail to effectively secure the oil pipes due to unreasonable initial clamping force settings, easily leading to oil pipe displacement, rupture, and oil leakage. Furthermore, due to the lack of adaptive capability, compatibility with different specifications of oil pipes is poor. During automobile production or repair, multiple clamps of different specifications with fixed clamping forces need to be prepared for different oil pipes, increasing the complexity and cost of parts management. In addition, existing devices lack fluid leakage alarm components. When an oil pipe leaks, the driver may not be able to detect it in time, potentially leading to serious safety accidents such as fires, posing a significant threat to the lives of passengers.

[0004] This utility model provides a hose clamp for automotive oil lines to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A hose clamp for automotive oil lines includes a mounting base, with connecting frames fixedly connected to the top of the front and rear sides of the mounting base. The left and right sides of the connecting frames are open structures.

[0020] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0021] like Figure 1-3 As shown, this utility model provides a hose clamp for automotive oil pipes, including a fixing base 10. A connecting frame 11 is fixedly connected to the top of the front and rear sides of the fixing base 10. The left and right sides of the connecting frame 11 are open structures. A fixing plate 12 is fixedly connected to the bottom of the front side wall of the connecting frame 11. A central controller 13 is fixedly connected to the rear side wall of the connecting frame 11. A pressure adaptive hose clamp assembly 2 is provided inside and above the connecting frame 11. A fluid leakage alarm assembly 3 is provided on the opposite side of the pressure adaptive hose clamp assembly 2.

[0022] The connecting frame 11 has an open structure on the left and right sides, providing space support for the rotation of the connecting rod 27. The central controller 13 is the core of the whole device and is responsible for controlling and coordinating the operation of various electrical components. The mounting base 10 has slots inside to facilitate the installation and operation of the rotating shaft 22 and the gear 23.

[0023] like Figure 4 , Figure 5 As shown, the pressure adaptive pipe clamp assembly 2 includes a motor 20. The bottom of the motor 20 is fixedly connected to the top of the fixing plate 12. The output end of the motor 20 extends through to the bottom of the fixing plate 12 and is fixedly connected to a gear 21. The upper and lower inner walls of the fixing base 10 are rotatably connected to a rotating shaft 22. The outer wall of the rotating shaft 22 is fixedly connected to a gear 23 that meshes with the gear 21.

[0024] like Figure 4 , Figure 5 As shown, the top of the rotating shaft 22 extends into the interior of the connecting frame 11 and is fixedly connected to a worm gear 24. The top of the worm gear 24 is rotatably connected to the inner top wall of the connecting frame 11. Both sides of the worm gear 24 are meshed with worm wheels 25, which are rotatably connected to the front inner wall of the connecting frame 11. Both rear walls of the left and right worm wheels 25 are fixedly connected to connecting rod 1 27. The two connecting rods 1 27 are symmetrically arranged on the left and right sides, and the ends away from the worm wheels 25 are rotatably connected to clamping rods 29. The top of the connecting frame 11 is fixedly connected to a fixing block 26. Both sides of the fixing block 26 are rotatably connected to connecting rod 28. The ends of the two connecting rods 28 are symmetrically arranged on the left and right sides, and the ends away from the fixing block 26 are rotatably connected to the middle of the left and right clamping rods 29 respectively.

[0025] like Figure 4 , Figure 5 As shown, arc-shaped clamping blocks 290 are fixedly connected to the top of the opposite surfaces of the two clamping rods 29, silicone shock-absorbing pads 291 are fixedly connected to the opposite surfaces of the two arc-shaped clamping blocks 290, and pressure sensors 292 are fixedly connected to the top of the opposite surfaces of the two silicone shock-absorbing pads 291. The central controller 13 is electrically connected to the motor 20 and the two pressure sensors 292 respectively.

[0026] During initial installation or when adjusting the clamping position of the oil pipe, the central controller 13 controls the motor 20 to operate. The output of the motor 20 drives the gear 21 to rotate. Since the gear 21 meshes with the gear 23 fixed on the rotating shaft 22, the rotating shaft 22 rotates accordingly. The worm 24 at the top of the rotating shaft 22 rotates as well. The worm 24 meshes with the worm wheels 25 on the left and right sides, thereby driving the two worm wheels 25 to rotate in opposite directions. The connecting rod 27 on the rear side wall of the worm wheel 25 rotates around the worm wheel 25. Simultaneously, the connecting rod 28 on the top fixing block 26 of the connecting frame 11 also moves in coordination, acting together on the clamping rod 29, causing the two clamping rods 29 to move relative to each other. The arc-shaped clamping block 290 on the top of the opposite side of the clamping rod 29 and the silicone shock-absorbing pad 291 on it clamp the car oil pipe. During the clamping process, the pressure sensor 292 monitors the magnitude of the clamping force in real time and converts the pressure data into an electrical signal, which is then transmitted to the central controller 13. The central controller 13 has a pre-set appropriate pressure range value. When it receives the pressure signal... After receiving the signal from sensor 292, the operating status of motor 20 is precisely controlled. For example, if pressure sensor 292 detects that the pressure exceeds the preset upper limit, the central controller 13 will issue a command to reverse motor 20 by a certain angle. Through the aforementioned series of transmission mechanisms, clamp rod 29 will be slightly loosened, thereby reducing the clamping pressure on the oil pipe. Conversely, if the pressure is lower than the preset lower limit, the central controller 13 will control motor 20 to rotate forward, allowing clamp rod 29 to further clamp the oil pipe. This cycle repeats, achieving adaptive dynamic adjustment of the oil pipe clamping pressure. Through the set pressure adaptive pipe clamp component 2, the clamping force on the oil pipe can be adjusted in real time according to the vehicle's movement status. This ensures that the oil pipe is firmly fixed in the pipe clamp, preventing displacement or shaking during vehicle operation, and also avoids damage to the oil pipe due to excessive clamping force, affecting its normal oil delivery function. At the same time, it can adapt to various oil pipe sizes and characteristics, reducing the trouble of frequently changing pipe clamps due to changes in oil pipe specifications, and improving the versatility and practicality of the pipe clamp.

[0027] like Figure 4 , Figure 5 As shown, the fluid leak alarm assembly 3 includes an ultrasonic sensor 30, which is fixedly connected to the bottom of the left side wall of the right silicone shock-absorbing pad 291. A buzzer 31 is fixedly connected to the top front side of the fixing plate 12. The central controller 13 is electrically connected to the buzzer 31 and the ultrasonic sensor 30 respectively.

[0028] During normal operation of the vehicle's fuel line, the fluid leak alarm component 3 is constantly monitoring. The ultrasonic sensor 30 continuously emits ultrasonic signals of a specific frequency into the surrounding environment and receives reflected ultrasonic signals. When the fuel line leaks due to some reason, such as pipe wall damage or poor sealing, the fluid flow at the leak point will disrupt the propagation path of the ultrasonic waves, causing significant changes in the intensity, frequency, and phase of the reflected signals received by the ultrasonic sensor 30. The ultrasonic sensor 30 can sensitively capture these signal changes and convert them into electrical signals, which are then transmitted to the central controller 13. Once the central controller 13 receives an abnormal signal from the ultrasonic sensor 30, it will immediately trigger the buzzer 31 on the front top of the fixed plate 12, which is electrically connected to it, causing the buzzer 31 to emit a loud alarm sound. Through the fluid leak alarm component 3, relevant personnel can be notified of a leak in the fuel line in a timely manner, thereby quickly taking corresponding repair or emergency measures, effectively avoiding a series of safety hazards caused by fuel line leaks, such as fires and engine failures that may be caused by fuel leaks, and ensuring the safe operation of the vehicle and the safety of the lives and property of the passengers.

[0029] It should be noted that the central controller 13, pressure sensor 292, ultrasonic sensor 30, and buzzer 31 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition, and principles are clear to those skilled in the art, so they will not be described in detail here.

[0030] The working principle of this automotive oil pipe clamp will be explained in detail below.

[0031] like Figure 1-5As shown, during initial installation or when adjusting the clamping state of the oil pipe, the central controller 13 controls the motor 20 to operate. The output end of the motor 20 drives the gear 21 to rotate. Since the gear 21 meshes with the gear 23 fixed on the rotating shaft 22, the rotating shaft 22 rotates accordingly. The worm 24 at the top of the rotating shaft 22 rotates as well. The worm 24 meshes with the worm wheels 25 on the left and right sides, thereby driving the two worm wheels 25 to rotate in opposite directions. The connecting rod 27 on the rear side wall of the worm wheel 25 is centered on the worm wheel 25. As the piston rotates, the connecting rod 28 on the top fixing block 26 of the connecting frame 11 also moves in coordination, acting together on the clamping rod 29, causing the two clamping rods 29 to move relative to each other. The arc-shaped clamping block 290 on the top of the opposite side of the clamping rod 29 and the silicone shock-absorbing pad 291 on it clamp the car oil pipe. During the clamping process, the pressure sensor 292 monitors the magnitude of the clamping force in real time and converts the pressure data into an electrical signal, which is then transmitted to the central controller 13. The central controller 13 has a pre-set appropriate pressure range value. When it receives a pressure signal... After receiving the signal from the force sensor 292, the operating status of the motor 20 is precisely controlled. For example, if the pressure sensor 292 detects that the pressure exceeds the preset upper limit, the central controller 13 will issue a command to reverse the motor 20 by a certain angle. Through the aforementioned series of transmission mechanisms, the clamping rod 29 will be slightly loosened, thereby reducing the clamping pressure on the oil pipe. Conversely, if the pressure is lower than the preset lower limit, the central controller 13 will control the motor 20 to rotate forward, allowing the clamping rod 29 to further clamp the oil pipe. This cycle repeats, achieving adaptive dynamic adjustment of the oil pipe clamping pressure. Through the pressure adaptive pipe clamp component 2, the clamping force on the oil pipe can be adjusted in real time according to the vehicle's movement status. This ensures that the oil pipe is firmly fixed in the pipe clamp, preventing displacement or shaking during vehicle operation. It also avoids damage to the oil pipe due to excessive clamping force, which would affect its normal oil delivery function. At the same time, it can adapt to various oil pipe sizes and characteristics, reducing the trouble of frequently changing pipe clamps due to changes in oil pipe specifications, and improving the versatility and practicality of the pipe clamp.

[0032] During normal operation of the vehicle's fuel line, the fluid leak alarm component 3 is constantly monitoring. The ultrasonic sensor 30 continuously emits ultrasonic signals of a specific frequency into the surrounding environment and receives reflected ultrasonic signals. When the fuel line leaks due to some reason, such as pipe wall damage or poor sealing, the fluid flow at the leak point will disrupt the propagation path of the ultrasonic waves, causing significant changes in the intensity, frequency, and phase of the reflected signals received by the ultrasonic sensor 30. The ultrasonic sensor 30 can sensitively capture these signal changes and convert them into electrical signals, which are then transmitted to the central controller 13. Once the central controller 13 receives an abnormal signal from the ultrasonic sensor 30, it will immediately trigger the buzzer 31 on the front top of the fixed plate 12, which is electrically connected to it, causing the buzzer 31 to emit a loud alarm sound. Through the fluid leak alarm component 3, relevant personnel can be notified of a leak in the fuel line in a timely manner, thereby quickly taking corresponding repair or emergency measures, effectively avoiding a series of safety hazards caused by fuel line leaks, such as fires and engine failures that may be caused by fuel leaks, and ensuring the safe operation of the vehicle and the safety of the lives and property of the passengers.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
