Description

Technical Field

[0001] The invention relates to the technical field of air pump detection, and in particular to a convenient and rapid detection box device for an air suspension air pump. Background Art

[0002] The working principle of the air suspension pump is to generate compressed air through the air compressor and send the compressed air into the air chamber of the air spring and shock absorber to change the height of the vehicle. Specifically, when the number of passengers or the load weight of the vehicle increases, the height of the vehicle body decreases. The control unit detects this change through the sensor and opens the inflation valve to allow compressed air to enter the air spring to raise the vehicle body. During the inflation process, the system will continuously monitor the height of the vehicle body. When the set value is reached, the valve will be closed to keep the vehicle body stable.

[0003] At present, the production of air suspension pumps requires them to be tested for inflation, pressure relief, vibration and noise. The existing testing method requires the air suspension pump to be installed on different testing equipment to complete the corresponding testing, which is not only troublesome but also costly. In addition, most of the existing testing devices are static testing, which cannot effectively simulate the working state of the air suspension pump under the actual operation of the car, resulting in a certain lack of authenticity and data deviation in the test data. Therefore, a testing device is needed that can simulate the actual operation situation and quickly complete the testing of the air suspension pump. Summary of the invention

[0023] The following is combined with Figure 1-Figure 6 The present invention is described in further detail.

[0024] The embodiment of the invention discloses a convenient and rapid detection box device for an air suspension air pump.

[0025] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] Example 1 In the existing technology, air suspension pump testing requires the use of multiple independent devices to complete the testing steps of inflation, pressure relief, vibration, etc. The operation process is cumbersome and the equipment purchase cost is high. Traditional testing devices use fixed excitation sources for static testing, which cannot restore the dynamic loads generated by road bumps during vehicle driving, resulting in deviations between the test data and the actual working conditions. During batch testing, an automotive parts testing center found that the existing equipment needed to repeatedly disassemble and assemble the tested parts, resulting in a single-piece testing time of more than 40 minutes, and the single vibration mode made it difficult to cover the testing requirements of different models.

[0027] In order to solve the above problems, the researchers observed that the dynamic load on the air spring 27 when the vehicle is driving comes from the periodic vibration caused by the unevenness of the road surface. By analyzing the vibration spectrum of the vehicle chassis, it is found that different road conditions can be decomposed into rotational excitation sources with different eccentric distances. Based on this, it is proposed to use a replaceable eccentric wheel group 5 to simulate multiple road conditions, and integrate the vibration excitation, height adjustment, and installation positioning functions into a single test box through an integrated structural design. In order to address the bottleneck of test efficiency, a transmission mechanism that can synchronously switch the eccentric wheel shape is designed to achieve rapid conversion of different vibration modes.

[0028] Therefore, refer to Figure 1-Figure 6 , this application proposes a convenient and rapid detection box device for air suspension pumps, including: The test box 1 has a box cover 12 rotatably hinged on its outer side, an operating panel 11 is fixedly connected inside the test box 1, and a hydraulic rod 8 is fixedly connected to the inner wall of the box cover 12. It should be noted that various operating buttons, pressure gauges and various joints are installed on the operating panel 11. When in use, the joints and the air pump are connected through air pipes for testing. The pressure gauge is convenient for observing the pressure data changes during the test process when the air intake and pressure relief are completed, and the air intake and pressure relief tests are completed, enriching the functions of the equipment; The bottom plate 2 is fixedly connected to the output end of the hydraulic rod 8, and a supporting mechanism is provided on a side of the bottom plate 2 away from the hydraulic rod 8; There are at least four eccentric wheel groups 5, and every two eccentric wheel groups 5 are set as a group to simulate different road conditions for automobile driving. An adjusting mechanism for controlling the switching of the eccentric wheel group 5 is set on the supporting mechanism, and a transmission mechanism for controlling the synchronous rotation of the eccentric wheel group 5 is also set on the inner side of the box cover 12. The shapes of each unit of the eccentric wheel group 5 are different. The top side of the eccentric wheel group 5 is provided with a mutually cooperating air pump installation mechanism, wherein the hydraulic rod 8 realizes the lifting and lowering of the base plate 2 through telescopic movement. The eccentric wheel group 5 refers to a rotating body with different eccentric distances, and can be processed into special-shaped structures such as ellipses and cams using aluminum alloy, and differentiated vibration waveforms are generated through rotation.

[0029] Specifically, the hydraulic rod 8 drives the base plate 2 to move vertically, so that an operating space is formed when the box cover 12 is opened and closed. The supporting mechanism and the base plate 2 form a partitioned bearing structure. The middle frame 23 provides a rigid support point. The eccentric wheel group 5 is installed through the rotating rod 37. The combination of monomers of different shapes can produce differentiated vibration spectra. The adjustment mechanism changes the angle of the turntable 33 through gear transmission, drives the curved rod 34 to push the rotating rod 37 axially to achieve rapid switching of the eccentric wheel monomers. The transmission mechanism engages with the flat gear 43 through the long gear 42, and synchronously transmits the power of the motor 4 to the rotating rod 37 to ensure that multiple groups of eccentric wheels rotate at the same frequency. The spring 27 buffer structure of the air pump installation mechanism absorbs high-frequency vibrations, and the movable rod 26 maintains contact with the top surface of the eccentric wheel, so that the tested piece is subjected to continuous dynamic loads.

[0030] Compared with the existing technology, the traditional test bench can only provide a single performance test mode, occupies a large space and has a high test cost. The present solution can simulate various typical road conditions such as gravel roads, speed bumps, and potholes through the replaceable eccentric wheel group 5. The existing equipment requires multiple independent devices to complete the test items, while the present solution can complete them in a single device.

[0031] Through the above technical scheme, the present application realizes the integrated detection of the air suspension pump under the simulation of real driving conditions, solves the efficiency bottleneck of multi-device detection, and the rapid switching mechanism of the eccentric wheel group 5 shortens the single-piece detection time to 2-5 minutes. The composite vibration generated by the special-shaped eccentric wheel group 5 effectively restores the dynamic load characteristics of the vehicle body, improves the consistency between the detection data and the actual road test results, and the integrated box structure enables the detection equipment to be conveniently moved to the production line for random online detection, avoiding repeated disassembly and assembly losses of the tested parts.

[0032] Example 2 Reference Figure 1 and Figure 3 The present application further proposes that the supporting mechanism includes a several-type bracket 21, a connecting seat 22 and an intermediate frame 23. There are at least four several-type brackets 21, two in a group, and each several-type bracket 21 is detachably connected to the base plate 2. The intermediate frame 23 is fixed on the surface of the base plate 2. The several-type brackets 21 are symmetrically distributed on both sides of the intermediate frame 23, and the connecting seat 22 is fixedly connected to the base plate 2.

[0033] Specifically, the several-type bracket 21, the connecting seat 22 and the intermediate stand 23 are used to support different components respectively, so as to ensure the supporting effect and allow the pressure to be distributed.

[0034] Example 3 Reference Figure 1 and Figure 4 The present application further proposes that the air pump installation mechanism includes a base 24, an air pump placement card plate 25, a movable rod 26 and a spring 27. The base 24 is detachably connected to the bracket 21. The spring 27 is connected between the base 24 and the air pump placement card plate 25. The movable rod 26 is fixedly connected to the bottom end of the air pump placement card plate 25. The movable rod 26 passes through the spring 27 and the base 24 and moves in coordination with the eccentric wheel group 5.

[0035] Among them, the air pump placement clamp 25 refers to a bearing platform for directly placing the test piece, which can be specifically implemented by a plate-like structure with a limiting boss on the surface, and can be selectively replaced according to the air pump model to improve the applicability of the equipment. The installation position of the air pump is constrained by the limiting boss to ensure the positioning accuracy during the detection process. Among them, the movable rod 26 refers to a transmission component connecting the vibration generating mechanism and the installation mechanism, which can be specifically implemented by a metal rod with a ball head structure at the end. The ball head structure forms a movable connection with the eccentric wheel group 5, so that the vibration energy is directly transmitted to the air pump through the rigid rod.

[0036] Specifically, when the air pump to be tested is placed between the limiting bosses of the card plate, the operator fixes the card seat 24 in the corresponding position of the bracket 21 by quick plug-in. During the detection process, the vibration generated by the eccentric wheel group 5 is directly transmitted to the card plate 25 for placing the air pump through the rigid rod body of the movable rod 26. At this time, the spring 27 undergoes compression deformation in the axial direction to buffer the impact load in the vertical direction, while maintaining the relative position of the card plate and the card seat 24 through its own elastic restoring force. The connection method in which the movable rod 26 passes through the spring 27 and the card seat 24 not only ensures the linearity of the vibration transmission path, but also avoids structural resonance caused by high-frequency vibration through the elastic support of the spring 27. It should be noted that when detecting the working data, it is necessary to install a vibration sensor on the outside of the air pump, and the prior art will not be described in detail.

[0037] Example 4 Reference Figure 1 , Figure 2 and Figure 4 The present application further proposes that the adjustment mechanism is provided with two groups, the adjustment mechanism includes a driving gear 31, a driven gear 32, a turntable 33 and a crank rod 34, the bottom of the intermediate frame 23 is fixedly connected to the motor 3, the output shaft of the motor 3 is coaxially fixedly connected to the driving gear 31, the driven gear 32 is meshed with the driving gear 31 for transmission, the turntable 33 is rotatably connected to the bottom end of the intermediate frame 23, and the center rod of the turntable 33 is transmission-connected to the center rod of the driven gear 32, a rotating rod 37 is movably connected to the connecting seat 22, the rotating rod 37 passes through the rotation center of each monomer of the eccentric wheel group 5, one end of the rotating rod 37 is movably connected to a sleeve 361, the outer wall of the sleeve 361 is detachably connected to an outer sleeve rod 36, the outer wall of the outer sleeve rod 36 is fixedly connected to a connecting sleeve 35, and a crank rod 34 is movably connected between the bottom of the connecting sleeve 35 and the turntable 33.

[0038] Among them, the function of the driving gear 31 and the driven gear 32 is to transmit the rotational motion output by the motor 3 to the driven gear 32 to control the transmission direction. Among them, the transmission connection between the turntable 33 and the center rod of the driven gear 32 refers to realizing the synchronous rotation of the center rotating rod of the turntable 33 and the center rod of the driven gear 32 through a gear set or a transmission belt structure, and its function is to convert the rotational motion of the gear into the planar motion of the turntable 33. The active connection between the curved rod 34 and the connecting sleeve 35 and the turntable 33 refers to realizing multi-degree-of-freedom motion through a hinge or a ball joint, and its function is to convert the rotational motion of the turntable 33 into the linear displacement of the eccentric wheel group 5.

[0039] Specifically, after the motor 3 is started, it drives the driving gear 31 to rotate, and the driving gear 31 and the driven gear 32 are meshed and transmitted to change the rotation direction. The driven gear 32 drives the turntable 33 to rotate around the bottom end of the intermediate frame 23 through the center rod. The rotation movement of the turntable 33 pushes the connecting sleeve 35 through the curved rod 34, driving the outer sleeve 36 and the clamping sleeve 361 to move along the axis of the rotating rod 37. The cooperation between the clamping sleeve 361 and the rotating rod 37 enables the eccentric wheel group 5 monomers to complete the switching synchronously with the movement of the rotating rod 37. When the clamping sleeve 361 moves to the preset position, the eccentric wheel monomer of a specific shape is locked in the working position. By controlling the start, stop and steering of the motor 3, the switching sequence and position of different monomers in the eccentric wheel group 5 can be accurately adjusted, thereby realizing the multi-road condition simulation function.

[0040] Through the above technical scheme, the present application can automatically switch eccentric wheels of different shapes according to the test requirements, simulating various road conditions encountered by the car when driving, such as bumps, gravel, normal driving, etc., to ensure the performance testing of the air suspension pump in a close to real working environment. The gear transmission system driven by the motor 3 and the linkage mechanism of the curved rod 34 effectively improve the switching speed and positioning accuracy. The detachable ferrule 361 structure further reduces the equipment maintenance cost, and provides technical guarantee for the reliability of dynamic detection data.

[0041] Example 5 The present application further proposes that the transmission mechanism includes a pulley group 41, a long gear 42 and a flat gear 43. The motor 4 is detachably connected to the box cover 12. The output shaft of the motor 4 is connected to the long gear 42 through the pulley group 41. The long gear 42 is arranged on the bottom side of the base plate 2. A through groove is opened on the base plate 2. The flat gear 43 is arranged in the through groove and meshes with the long gear 42 for transmission. The flat gear 43 is coaxially fixedly connected to the rotating rod 37.

[0042] Among them, the pulley group 41 refers to a component that realizes power transmission through belt drive, which can be specifically realized by a multi-groove synchronous pulley group, and is used to transmit the rotational power of the motor 4 to the long gear 42. The long gear 42 refers to a spur gear arranged along the length direction of the base plate 2, and its bottom side arrangement can avoid spatial interference with the upper vibration component. The flat gear 43 refers to a cylindrical gear with a thinned axial thickness, so that it can both mesh with the long gear 42 and form a coaxial transmission with the rotating rod 37.

[0043] Specifically, the motor 4 is fixed to the inner side of the box cover 12 through a detachable interface, and its output shaft drives the long gear 42 to rotate through the pulley group 41. The tooth surface of the flat gear 43 maintains a continuous meshing state with the long gear 42, and the flat gear 43 is driven to rotate through the long gear 42. When the rotating rod 37 needs to drive the eccentric wheel group 5, the rotational movement of the flat gear 43 is directly converted into the circumferential rotation of the rotating rod 37 through the coaxial connection with the rotating rod 37, thereby controlling the rotation of the eccentric wheel group 5.

[0044] Example 6 Reference Figure 1 and Figure 6 The present application further proposes that the monomers of the eccentric wheel group 5 are divided into two types of eccentric wheels, one with a rough surface and the other with a smooth surface.

[0045] Among them, the eccentric wheel with rough surface refers to the eccentric wheel with uniform grain texture formed by sandblasting on the wheel body surface and the eccentric wheel with other raised textures on the surface, such as Figure 6 As shown, Figure 6 Among them, wheel a, wheel e and wheel d are all eccentric wheels with rough surfaces, among which wheel d has a surface roughness of Ra6.3-12.5μm, which is used to generate high-frequency vibrations and irregular impact loads during rotation to simulate conventional gravel roads. The eccentric wheel with a smooth surface refers to an eccentric wheel with a polished or coated wheel surface. Wheels b and c are eccentric wheels with smooth surfaces, which are used to generate low-frequency regular vibrations to simulate normal driving on conventional roads. The differences in physical surface characteristics of these two types of eccentric wheels correspond to the mechanical transfer characteristics of uneven roads and flat road conditions during car driving.

[0046] Specifically, during the test, the eccentric wheel with a rough surface generates a wider range of vibration frequency distribution when it rotates, and its granular surface forms a transient impact when it contacts the air pump installation mechanism, simulating the random vibration caused by the gravel road surface. Figure 6The d wheel is used to simulate stable driving on gravel roads, the e wheel is used to simulate driving on speed bumps, the a wheel is elliptical and is in intermittent contact with the movable rod 26, simulating the vibration of a pothole encountered during normal driving on a bumpy road; the eccentric wheel with a smooth surface transmits regular vibration waves through uniform rotational contact, simulating the periodic bumps of paved roads. It should be noted that the b wheel is in intermittent contact with the movable rod 26, simulating the vibration of a pothole encountered suddenly on a regular road. The two eccentric wheels can be driven by a transmission mechanism to achieve alternating or superimposed operation, so that the air pump can simultaneously withstand the composite load of high-frequency vibration and low-frequency vibration, thereby accurately reproducing the complex dynamic stress actually borne by the air suspension system when the vehicle is driving. The selection of different eccentric wheel monomers enriches the functions of the detection equipment.

[0047] Through the above-mentioned technical scheme, the present application can simultaneously complete the performance test of the air pump under two typical working conditions, gravel road surface and paved road surface, within one detection cycle, effectively identify the sealing performance degradation problem of the air pump under high-frequency impact load, and the pressure control stability in low-frequency vibration environment, significantly improving the coverage and prediction accuracy of the detection data for actual usage conditions.

[0048] Example 7 Reference Figure 3 and Figure 5 The present application further proposes that a storage strip 121 is fixedly connected to the inner wall of the box cover 12, and a plurality of receiving grooves are provided on the storage strip 121. A slot is provided on the surface of the bottom plate 2, and a detachable sound insulation cover mechanism 7 is inserted in the slot. The sound insulation cover mechanism 7 includes a short side plate 71, a long side plate 72 and a top cover plate 73. After disassembly, the short side plates 71, the long side plates 72 and the top cover plate 73 are respectively stored in different receiving grooves. Semi-cylinders 74 are provided on the top of the short side plates 71 and the long side plates 72, and a through hole that is plugged into the semi-cylinder 74 is provided on one side of the top cover plate 73. A wiring hole 721 is provided on the surface of the long side plate 72, and the short side plates 71, the long side plates 72 and the top cover plate 73 are all filled with sound insulation cotton.

[0049] Specifically, the storage strip 121 stores the various components of the sound insulation cover mechanism 7 in a classified manner through the receiving grooves. When a noise isolation test is required, the operator takes out the short side panels 71, the long side panels 72 and the top cover panel 73 from the storage strip 121, inserts the bottoms of the short side panels 71 and the long side panels 72 into the slots on the surface of the bottom plate 2, and then plugs the top cover panel 73 into the semi-cylindrical structure 74 on the top of the side panel to form a complete sound insulation cover. After the test is completed, the various components are disassembled and reclassified and stored in the receiving grooves of the storage strip 121. This process achieves rapid positioning through the guiding effect of the slots, and ensures the overall sealing of the sound insulation cover through the mechanical connection between the panels. The detection mechanism in the sound insulation area can be set as a static group, and no road conditions are simulated for detection, thereby providing a control group test to observe the vibration waveform and other electrical parameters, so as to improve the accuracy of the data.

[0050] Among them, the wiring hole 721 is automatically aligned with the equipment cable outlet when the long side plate 72 is assembled. The operator can pass the sensor cable through the hole to connect the detection equipment. After the detection is completed, the top cover plate 73 can be vertically lifted up and separated from the semi-cylinder 74, and the short side plate 71 and the long side plate 72 are respectively taken out of the slot and placed separately in the receiving grooves corresponding to the storage plate strips 121.

[0051] Example 8 Reference Figure 2 and Figure 4 The present application further proposes that the bottom end of the bracket 21 away from the long gear 42 is fixedly connected to the bottom sealing cover 6, and a rectangular groove communicating with the bottom sealing cover 6 is provided on the surface of the bottom plate 2.

[0052] Specifically, the rigid connection between the bottom sealing cover 6 and the bracket 21 forms a semi-enclosed cavity. When in use, a sealed space is formed with the sound insulation cover mechanism 7 to reduce external noise interference. When the detection equipment is running, but in restriction, the air pump placement card 25 and its related components can be removed and placed in the bottom sealing cover 6 from the rectangular groove for storage to prevent the test box 1 and the box cover 12 from being unable to close.

[0053] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
