Description

Technical Field

[0001] This utility model relates to the field of airbag detection technology, specifically to an airbag deformation detection device for an airbag shock absorber. Background Technology

[0002] Motorcycle air spring shock absorbers are devices that use air springs as the primary shock-absorbing element. Unlike traditional spring shock absorbers, air spring shock absorbers absorb and mitigate impacts and vibrations from the road surface by compressing or releasing gas. The advantages of motorcycle air spring shock absorbers include easy adjustment, adjustable shock absorption, and better ride comfort.

[0003] Airbags, made of high-strength, durable rubber composite materials, are shaped like a ring or sac and serve as the primary load-bearing and elastic element. Under prolonged exposure to high pressure, repeated compression and rebound, extreme road conditions, or overload, airbags can undergo excessive deformation beyond their design limits, even resulting in irreversible permanent deformation (such as bulges, dents, or localized expansion). Deformation is often a precursor to airbag rupture (such as the appearance of cracks or delamination). Sudden airbag rupture during riding causes the suspension to collapse instantly, resulting in the motorcycle completely losing support and shock absorption, which can easily lead to loss of vehicle control and poses a significant threat to rider safety. Therefore, it is necessary to test the degree of airbag deformation.

[0004] An airbag shock absorber consists of a spherical rubber airbag and two parallel cover plates. Airbag shock absorbers with different structural dimensions will exhibit different airbag deformations under the same load. Therefore, it is necessary to measure the airbag deformation of airbag shock absorbers of different sizes under different pressures to ensure the quality of the airbag shock absorbers.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0009] Furthermore, in order to effectively control the height adjustment of the lifting plate according to the height of the airbag shock absorber, and to facilitate subsequent impact testing to detect changes in airbag shape, the inner bottom of the worktable is provided with limiting posts around the perimeter to cooperate with the lifting plate and lifting mechanism.

Sliding blocks are symmetrically arranged at both ends of the external threads. A first rotating rod is connected to the outer side of one set of sliding blocks, and a second rotating rod cooperating with another set of sliding blocks is connected to the bottom end of the first rotating rod. Both the first and second rotating rods cooperate with the supporting plates.

[0010] Furthermore, in order to effectively clamp airbag shock absorbers of different sizes and prevent the airbag shock absorbers from changing position under different pressures, thereby affecting the accuracy of airbag deformation detection, the clamping mechanism includes a mounting base located at the top center of the lifting plate. A pushing block is located in the center of the mounting base, and sliders are symmetrically arranged at both ends of the pushing block and inside the mounting base. A second motor is located in the center of one side wall of the mounting base, and the output shaft of the second motor passes through the side wall of the mounting base and is provided with a first threaded rod.

The cross-section of the pushing block is set as a trapezoidal structure, and the two side walls of the pushing block are provided with limiting blocks that cooperate with the sliders, and the cross-section of the limiting blocks is also set as a trapezoidal structure. One side wall of the slider is set as an inclined surface, and a limiting groove that cooperates with the limiting block is opened in the middle of the inclined surface. Slide rails that cooperate with the sliding grooves are symmetrically arranged at the top and bottom ends of the slider. A clamping plate is provided on one side wall of the slider, and the end of the clamping plate away from the slider is set as an arc structure.

[0011] Furthermore, in order to apply different pressure loads to the airbag shock absorber and to conduct more comprehensive and accurate detection of the airbag deformation, ensuring the accuracy of the airbag deformation data, the impact hammer includes a magnetic block set at the bottom of the electromagnet, a second threaded rod passing through the middle of the top of the magnetic block, an impact block set at the end of the second threaded rod away from the magnetic block, a number of counterweights cooperating with the second threaded rod set at the top of the impact block, and a nut cooperating with the second threaded rod set at the top of the topmost counterweight.

Detailed Implementation

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, an airbag deformation detection device for an airbag shock absorber is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6As shown, the airbag deformation detection device for an airbag shock absorber according to an embodiment of the present invention includes: a workbench 1; a control panel 2 disposed on one side of the workbench 1; a lifting plate 3 disposed inside the workbench 1; a lifting mechanism 4 disposed at the bottom of the lifting plate 3 for adjusting the height of the lifting plate 3; a clamping mechanism 5 disposed at the top of the lifting plate 3 for clamping the airbag shock absorber; an impact tube 6 disposed at the top of the workbench 1; a mounting door 7 opened at the bottom side of the impact tube 6; a support frame 8 disposed at the top of the impact tube 6; a winch 9 disposed at the top of the support frame 8; an electromagnet 10 disposed at the bottom of the winch 9; an impact hammer 11 disposed at the bottom of the electromagnet 10 for impacting the airbag shock absorber; and a plurality of ultrasonic sensors 12 disposed on the inner wall of the workbench 1 for detecting the degree of deformation of the airbag shock absorber.

[0028] By utilizing the aforementioned technical solution, this utility model, through the combined action of the workbench 1, control panel 2, lifting plate 3, lifting mechanism 4, clamping mechanism 5, winch 9, electromagnet 10, impact hammer 11, and ultrasonic sensor 12, can measure the deformation degree of airbags of different sizes under different pressures, thus ensuring the quality of the airbags. The workbench 1, control panel 2, lifting plate 3, lifting mechanism 4, and clamping mechanism 5 can effectively clamp airbags of different heights, preventing positional changes under different pressures and thus affecting the accuracy of airbag deformation detection. The winch 9, electromagnet 10, and impact hammer 11 can apply different pressure loads to the airbags, enabling more comprehensive and accurate detection of airbag deformation, ensuring the precision of the airbag deformation data.

[0029] It should be explained that the winch 9 is a mechanical device driven by an electric motor for lifting or pulling heavy objects. The winch 9 consists of an electric motor, a reducer, a drum, a rope, a brake, a control system, a base, and a rope guide. The electric motor is the power source of the electric winch, usually an AC motor or a DC motor. The reducer is used to reduce the output speed of the electric motor and increase the torque to better meet the lifting requirements of the heavy objects. The drum is used to wind the wire rope or rope. The diameter and width of the drum affect the lifting capacity of the winch and the capacity of the rope. The rope connects the drum and the heavy object, and is used to transmit force and lift the heavy object. The brake is used to control the movement of the winch and prevent slippage or loss of control during lifting or lowering. The control system includes an electrical control box and operating buttons for operators to control the start, stop, lifting, and lowering of the winch. The base is used to support and fix other components of the winch to ensure the stability and safety of the equipment. The rope guide is used to guide the direction of the wire rope and prevent the rope from winding unevenly on the drum or derailing. This is existing technology and will not be described further.

[0030] The electromagnet 10 mainly consists of a coil and an iron core. The coil is usually made of insulated wire, while the iron core is generally made of soft iron or other easily magnetized materials. When current passes through the coil, the iron core is magnetized, forming a strong magnetic field, thus making the electromagnet 10 magnetic. Here, the electromagnet can be a suction cup type electromagnet to ensure full contact with the impact hammer 11. The steel cable or chain of the winch 9 is connected to the electromagnet 10. The power system of the winch 9 lifts the electromagnet and the attached magnetic material together to the required height or position. Both the winch 9 and the electromagnet 10 are electrically connected to the control panel 2. This is existing technology and will not be described further here.

[0031] The ultrasonic sensor 12 mainly consists of a transducer, a transmitter, and a receiver. The transducer is the core component of the ultrasonic sensor, used to transmit and receive ultrasonic waves. The transducer is usually made of piezoelectric material and can convert electrical signals into sound waves (ultrasonic waves), and in turn, convert the received sound waves back into electrical signals. The transmitter is used to generate ultrasonic signals. Excited by an electrical signal, the transmitter converts the electrical signal into ultrasonic waves and sends them to the target object. The receiver is used to receive the ultrasonic waves reflected from the target object. The receiver converts the reflected ultrasonic waves back into electrical signals for subsequent processing. The ultrasonic sensor 12 is electrically connected to the control panel 2, which is prior art and will not be described here.

[0032] In applications that detect the degree of airbag deformation, the ultrasonic sensor 12 can determine the distance change on the airbag surface by measuring the reflection time (time difference). The control panel 2 controls and activates the ultrasonic sensor 12, causing the sensor to emit ultrasonic waves. The sound waves propagate to the airbag surface and are reflected back. The receiver of the ultrasonic sensor 12 receives the reflected ultrasonic waves and converts them into electrical signals. By measuring the time difference between the emission and reception of the ultrasonic waves, the distance change on the airbag surface is calculated, thereby accurately calculating the degree of airbag deformation. The control panel 2 analyzes the electrical signals to determine whether the airbag has deformed and the specific degree of deformation.

[0033] Furthermore, the airbag deformation detection device of this utility model can not only detect the deformation of the airbag of the airbag shock absorber, but also adapt to other types of airbags by changing the parameters of the clamping mechanism 5 and the impact hammer 11, and perform deformation detection according to the characteristics of other types of airbags, thereby effectively ensuring the quality of gas-type airbags.

[0034] In one embodiment, for the workbench 1, lifting plate 3, and lifting mechanism 4 described above, the workbench 1 has limiting posts 13 around its inner bottom perimeter that cooperate with the lifting plate 3 and lifting mechanism 4, and support posts 14 symmetrically arranged at both ends of its inner bottom perimeter that cooperate with the lifting mechanism 4; the lifting plate 3 has through holes 15 around its top perimeter that cooperate with the limiting posts 13, and support plates 16 symmetrically arranged at the center of its bottom perimeter that cooperate with the lifting mechanism 4; the lifting mechanism 4 includes a first motor 401 located at the inner bottom perimeter of the workbench 1, and the output end of the first motor 401 has a rotating shaft that cooperates with the support posts 14. 402, both ends of the rotating shaft 402 are provided with external threads 403, and the thread directions of the external threads 403 at both ends of the rotating shaft 402 are opposite. Sliding blocks 404 are symmetrically arranged at both ends of the external threads 403. A first rotating rod 405 is connected to the outer side of one set of sliding blocks 404. The bottom end of the first rotating rod 405 is connected to a second rotating rod 406 that cooperates with another set of sliding blocks 404. The first rotating rod 405 and the second rotating rod 406 both cooperate with the support plate 16, so that the height of the lifting plate 3 can be effectively controlled according to the height of the airbag shock absorber, making it convenient to detect the shape change of the airbag in subsequent impact tests.

[0035] The working principle of the workbench 1, lifting plate 3, and lifting mechanism 4 is as follows: In the initial state, the operator controls and starts the first motor 401 under the control panel 2. Under the action of the output shaft of the first motor 401, the rotating shaft 402 is driven to rotate. Under the action of the support column 14, the rotating shaft 402 rotates stably. During the rotation of the rotating shaft 402, the sliding block 404 is moved. The sliding block 404 is respectively sleeved at the opposite positions of the thread direction of the external thread 403 at both ends of the rotating shaft 402. During the rotation of the rotating shaft 402, the sliding block 404 will move towards each other in the horizontal direction of the rotating shaft 402. During the movement of the sliding block 404, one end of the first rotating rod 405 and the second rotating rod 406 will move towards each other. Under the limiting action of the support plate 16, the lifting plate 3 moves vertically during the movement of one end of the first rotating rod 405 and the second rotating rod 406. Under the limiting action of the limiting column 13, the lifting plate 3 moves stably in the vertical direction, realizing the height adjustment of the lifting plate 3.

[0036] In one embodiment, the clamping mechanism 5 includes a mounting base 501 located at the center of the top of the lifting plate 3. A push block 502 is located in the center of the mounting base 501. Slider blocks 503 are symmetrically arranged at both ends of the push block 502 and inside the mounting base 501. A second motor 504 is located in the center of one side wall of the mounting base 501, and the output shaft of the second motor 504 passes through the side wall of the mounting base 501 and is provided with a first threaded rod 505. The inner top and inner bottom of the mounting base 501 are symmetrically provided with grooves 506 that cooperate with the sliders 503. The cross-section of the push block 502 is set as a trapezoidal structure. Each end sidewall is provided with a limiting block 507 that cooperates with the slider 503, and the cross-section of the limiting block 507 is set as a trapezoidal structure; one sidewall of the slider 503 is set as an inclined surface, and a limiting groove 508 that cooperates with the limiting block 507 is opened in the middle of the inclined surface; the top and bottom ends of the slider 503 are symmetrically provided with slide rails 509 that cooperate with slide grooves 506; one end sidewall of the slider 503 is provided with a clamping plate 510, and the end of the clamping plate away from the slider 503 is set as an arc structure, so as to effectively clamp airbag shock absorbers of different sizes and prevent the position of the airbag shock absorber from changing when subjected to different pressures, thereby affecting the accuracy of airbag deformation detection.

[0037] In addition, in specific applications, the inner wall of the clamping plate 510 is equipped with a pressure sensor. Through the human-machine interface (HMI) of the control panel 2, the operator can perform system initialization settings and real-time monitoring. The PLC (programmable logic controller) of the control panel 2 presets the clamping force threshold and control logic (for example, stopping the motor when the set clamping force is reached). During operation, the PLC of the control panel 2 adjusts the clamping force to ensure stability by monitoring the status of the clamping mechanism and the feedback signal of the pressure sensor in real time.

[0038] The working principle of the clamping mechanism 5 is as follows: In the initial state, the operator controls and starts the second motor 504 under the control of the control panel 2. Under the action of the output shaft of the second motor 504, the first threaded rod 505 is driven to rotate clockwise. Under the action of the clockwise rotation of the first threaded rod 505, the pushing block 502 is driven to move to one side of the second motor 504. With the cooperation of the limiting block 507, the limiting groove 508, the sliding groove 506, and the sliding rail 509, the slider 503 is driven to move towards the inside of the mounting base 501, thereby driving the clamping plate 510 to move inward. Then, under the action of the two clamping plates 510, the bottom end of the airbag shock absorber is clamped. The cover plate is clamped and fixed; conversely, under the control panel 2, the second motor 504 is controlled and started. Under the action of the output shaft of the second motor 504, the first threaded rod 505 is driven to rotate counterclockwise. Under the action of the first threaded rod 505 rotating counterclockwise, the push block 502 is driven to move away from the second motor 504. With the cooperation of the limiting block 507, the limiting groove 508, the sliding groove 506, and the sliding rail 509, the slider 503 is driven to move towards the outside of the mounting base 501, thereby driving the clamping plate 510 to move outward. Then, under the action of the two clamping plates 510, the fixation of the cover plate at the bottom of the airbag shock absorber is released.

[0039] In one embodiment, the impact hammer 11 includes a magnetic block 1101 disposed at the bottom of the electromagnet 10. A second threaded rod 1102 is disposed through the middle of the top of the magnetic block 1101. An impact block 1103 is disposed at the end of the second threaded rod 1102 away from the magnetic block 1101. A plurality of counterweights 1104 that cooperate with the second threaded rod 1102 are disposed at the top of the impact block 1103. A nut 1105 that cooperates with the second threaded rod 1102 is disposed at the top of the topmost counterweight 1104. This allows different pressure loads to be applied to the airbag shock absorber, enabling more comprehensive and accurate detection of the airbag deformation and ensuring the accuracy of the airbag deformation data.

[0040] It should be explained that the magnetic block 1101 can be made of silicon steel or nickel-iron alloy. The magnetic block 1101 can be effectively attracted by the magnetic field of the electromagnet 10. The counterweight 1104 can be a weight, which can apply different pressure loads to the airbag shock absorber.

[0041] The working principle of the impact hammer 11 is as follows: In the initial state, the operator unscrews the magnetic block 1101 and the nut 1105 in sequence, selects an appropriate number of counterweights 1104, places the appropriate number of counterweights 1104 on the impact block 1103, screws the nut 1105 along the second threaded rod 1102 onto the top of the top counterweight 1104, and then screws the magnetic block 1101 back on.

[0042] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0043] In practical application, initially, the operator opens the door of workbench 1 (located on the front of the workbench, and the door of workbench 1 and workbench 1 can be connected by hinges). Based on the height of the airbag shock absorber, the operator controls and starts the first motor 401 under the control panel 2. Under the action of the output of the first motor 401, the rotating shaft 402 is controlled to rotate. After adjusting the lifting plate 3 to a suitable height (the working principles of workbench 1, lifting plate 3, and lifting mechanism 4 are as described above), the operator controls and stops the first motor 401 under the control panel 2, places the airbag shock absorber on the lifting plate 3, and controls and starts the second motor 504 under the control panel 2. Under the action of the output of the second motor 504 and the pressure sensor... The clamping plate 510 clamps the cover plate at the bottom of the airbag shock absorber (the working principle of the clamping mechanism 5 is as described above). The operator installs the counterweight 1104 on the impact hammer 11 (the working principle of the impact hammer 11 is as described above), opens the installation door 7 (the installation door 7 and the impact tube 6 can be connected by a hinge), and the electromagnet 10 is energized. The electromagnet 10 attracts the impact hammer 11. The installation door 7 is closed, and the winch 9 is controlled and started under the control panel 2. The winch 9 drives the impact hammer 11 to rise to different heights and then releases it, thereby generating different pressure loads on the airbag shock absorber. The ultrasonic sensor 12 measures the degree of deformation of the airbag in the airbag shock absorber under different pressure loads during the impact of the impact hammer 11 on the airbag shock absorber.

[0044] In summary, by utilizing the above-mentioned technical solution of this utility model, the combined action of the workbench 1, control panel 2, lifting plate 3, lifting mechanism 4, clamping mechanism 5, winch 9, electromagnet 10, impact hammer 11, and ultrasonic sensor 12 enables the measurement of the deformation degree of airbags of different sizes under different pressures, thus ensuring the quality of the airbags. The combined action of the workbench 1, control panel 2, lifting plate 3, lifting mechanism 4, and clamping mechanism 5 effectively clamps airbags of different heights, preventing positional changes under different pressures and thus affecting the accuracy of airbag deformation detection. The combined action of the winch 9, electromagnet 10, and impact hammer 11 applies different pressure loads to the airbags, enabling more comprehensive and accurate detection of airbag deformation, ensuring the precision of the airbag deformation data.
