Automobile height sensor installation detection apparatus and method of use thereof

Abstract

This invention relates to the field of automotive testing technology and discloses an automotive height sensor installation and testing device and its usage method. The device includes a track with several support legs fixedly connected to its bottom, and a threaded rod inside the track. By setting up a moving testing mechanism, when the threaded sleeve moves the testing platform along an auxiliary slide bar to the vicinity of the moving testing mechanism, the push plate at the bottom of the car chassis contacts the passive rod on the moving block. At this time, the push plate drives the moving block on the passive rod to slide along the slide bar, and the moving block drives the moving rod to slide along the limiting groove. The moving block also drives the protective cover at the top of the moving rod to move. Simultaneously, the laser measuring instrument inside the protective cover moves synchronously with the car chassis on the testing platform. This arrangement helps ensure that the laser measuring instruments remain relatively stationary with the car chassis during movement, thus improving the accuracy of the laser measuring instruments in detecting the car chassis.

Description

Technical Field

[0001] This invention relates to the field of automotive testing equipment technology, specifically to an automotive height sensor installation and testing device and its usage method. Background Technology

[0002] Vehicle height sensors are used in air suspension and active suspension systems in automobiles to detect vehicle height (the relative displacement between the vehicle body and the lower suspension arm or shock absorber support in the vertical direction). Traditional detection equipment typically uses photoelectric sensors; the sensor body is mounted on the vehicle body, and the vertical movement of the suspension is converted into the rotational movement of a disk slot via control links. The change in the output of the photoelectric sensor is used to detect the vehicle height, and this is converted into an electrical signal input to the control device.

[0003] The height sensor is mounted on the car chassis via a bracket. The installation of the height sensor requires very strict control; if the installation position is too high or too low, outside the optimal working range, the height sensor will malfunction. Therefore, after installation, the height sensor needs to be checked using testing equipment to ensure that the installation position is within the optimal working range. Currently, most automotive manufacturing processes rely on moving inspections on assembly lines. The car moves along the assembly line to the inspection equipment for testing. This process involves the inspection equipment constantly detecting moving cars, and errors inevitably occur during this movement, resulting in inaccurate inspections. Summary of the Invention

[0004] The purpose of this invention is to provide an automotive height sensor installation and detection device and its usage method to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

The movable detection mechanism includes several fixed blocks fixedly connected to the bottom of the equipment track. A sliding rod is fixedly connected to the side wall of each fixed block, and a movable block is slidably connected to the sliding rod.

[0009] Furthermore, the mobile detection mechanism also includes a moving rod fixedly connected to the top of the moving block one. A limit groove is opened directly above the equipment track, and the moving rod slides inside the limit groove. A protective cover is fixedly connected to the end of the moving rod away from the moving block one, and the laser measuring instrument is set inside the protective cover.

[0010] Furthermore, the mobile detection mechanism also includes several push plates fixedly connected to the bottom of the vehicle chassis. A passive rod slides through the interior of the first moving block, and the push plates and the passive rod press against each other. The second moving block is slidably connected to the sliding rod.

[0011] Furthermore, an adjustment mechanism is provided on the first movable block. The adjustment mechanism includes a lead screw rotatably connected to one side wall of the movable block. The second movable block is rotatably connected to the lead screw, and a rotating handle is fixedly connected to the end of the lead screw away from the first movable block.

[0012] Furthermore, a reset mechanism is provided on the passive rod. The reset mechanism includes a reset spring sleeved on the end of the sliding rod near the moving block. A pressing rod is fixedly connected to the end of the passive rod away from the push plate. Several irregular sliding grooves are opened directly above the equipment track. The pressing rod slides inside the irregular sliding grooves. A linkage rod is rotatably connected to the end of the pressing rod away from the passive rod. The end of the linkage rod away from the pressing rod is rotatably connected to the moving rod.

[0013] Furthermore, a buffer mechanism is provided on the fixed block. The buffer mechanism includes a fixed column fixedly connected to one side of the fixed block. A piston plate is fixedly connected to the end of the fixed column away from the fixed block. A buffer cylinder is fixedly connected to the side of the movable block two near the piston plate. The piston plate and the buffer cylinder are slidably connected. An air vent is opened inside the movable block two. An air vent pipe is fixedly connected to the movable block two. The end of the air vent pipe away from the movable block two is fixedly connected to the protective cover. A hose is fixedly connected to one side of the movable block two. The end of the hose away from the movable block two is fixedly connected to the movable block one.

[0014] A vehicle height sensor installation detection device and its usage method include the following steps:

[0015] Step 1: The car chassis moves stably;

[0016] Step 2: The car chassis and the laser measuring instrument are kept relatively stationary during the inspection;

[0017] Step 3: Adjust the position of the laser measuring instrument;

[0018] Step 4: Reset the laser measuring instrument to enable continuous detection;

[0019] Step 5: Reset the laser measuring instrument buffer.

[0020] The present invention has the following beneficial effects:

[0021] (1) In this invention, by setting up a moving detection mechanism, when the threaded sleeve drives the detection platform to move along the auxiliary slide bar to the vicinity of the moving detection mechanism, the push plate at the bottom of the car chassis contacts the passive rod on the moving block one. At this time, the push plate drives the moving block one on the passive rod to slide along the slide bar, the moving block one drives the moving rod to slide along the limit groove, and the moving block one drives the protective cover at the top of the moving rod to move. At this time, the laser measuring instrument inside the protective cover moves synchronously with the car chassis on the detection platform. This setting is conducive to ensuring that several laser measuring instruments and the car chassis remain relatively stationary during the movement, which is conducive to improving the accuracy of the laser measuring instrument in the device for detecting the car chassis.

[0022] (2) When using the detection equipment, the car chassis is first fixedly installed on the detection platform directly above the sliding base. The drive motor is started, and the output end of the drive motor rotates to drive the output shaft to rotate. The output shaft rotates to drive the gear to rotate. The gear rotates to drive the threaded sleeve on the gear ring to rotate. The threaded sleeve rotates to drive the sliding base on the threaded sleeve to move along the threaded rod. The movement of the sliding base drives the car chassis directly above the detection platform to move along the auxiliary slide rod. This setting is conducive to making the car chassis move stably and horizontally along the inside of the equipment track, so that the height sensor will not shake during the detection process, thereby improving the accuracy of the detection.

[0023] (3) In this invention, by setting a reset mechanism, when the moving block 1 drives the moving rod to slide along the limiting groove, the moving rod drives the pressing rod at one end of the linkage rod to move along the irregular sliding groove. When the pressing rod slides to a point away from the moving rod, the pressing rod presses against the irregular sliding groove. The pressing rod drives the passive rod to slide outward along the moving block 1. When the push plate and the passive rod disengage, the moving block 1 resets under the pressing action of the reset spring. This setting is beneficial for several laser measuring instruments to return to their initial positions, and facilitates the device to continuously detect whether the height sensor on the car chassis is installed correctly.

[0024] (4) In this invention, by setting a buffer mechanism, when the reset spring presses the moving block one to reset, the moving block one drives the moving block two at one end of the screw to slide and reset along the sliding rod. At this time, the moving block two drives the buffer cylinder to slide relative to the piston plate on the fixed column. This setting helps to ensure that the laser measuring instrument resets more smoothly and avoids the reset spring pressing the sliding rod quickly, causing the laser measuring instrument on the sliding rod to shake violently due to inertia. At the same time, the gas inside the buffer cylinder is squeezed by the piston plate and enters the gas outlet pipe through the gas outlet hole. The gas inside the gas outlet pipe is discharged into the protective cover. This setting helps to cool down the laser measuring instrument inside the protective cover on the one hand, and helps to remove the dust inside the protective cover on the other hand, thereby ensuring the normal operation of the laser measuring instrument.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1, please refer to Figure 1 - Figure 6 As shown, this invention relates to a vehicle height sensor installation and testing device and its usage method, including a device track 1, a plurality of support legs 11 fixedly connected to the bottom of the device track 1, a threaded rod 12 disposed inside the device track 1, a sliding base 13 slidably connected to the middle of the threaded rod 12, a testing platform 14 fixedly connected directly above the sliding base 13, a vehicle chassis 15 disposed directly above the testing platform 14, a plurality of laser measuring instruments 16 disposed inside the device track 1, and further including:

[0040] The moving mechanism 2 includes a drive motor 201 fixedly connected to the side wall of the sliding base 13. An output shaft 202 is fixedly connected to the output end of the drive motor 201. A threaded sleeve 203 is rotatably connected to the inner wall of the sliding base 13. A gear 204 is fixedly connected to the end of the output shaft 202 away from the drive motor 201. A gear ring 205 is fixedly connected to the outer wall of the threaded sleeve 203, meshing with the gear 204. Several auxiliary slide rods 206 are provided inside the equipment track 1, and the sliding base 13 is slidably connected to the auxiliary slide rods 206. The function of this component is to first fix the car chassis 15 directly on the sliding base 13 when using the testing equipment. On the detection platform 14, the drive motor 201 is started. The output end of the drive motor 201 rotates, which drives the output shaft 202 to rotate. The rotation of the output shaft 202 drives the gear 204 to rotate. The rotation of the gear 204 drives the threaded sleeve 203 on the gear ring 205 to rotate. The rotation of the threaded sleeve 203 drives the sliding base 13 on the threaded sleeve 203 to move along the threaded rod 12. The movement of the sliding base 13 drives the car chassis 15 directly above the detection platform 14 to move along the auxiliary slide rod 206. This setting helps to make the car chassis 15 move stably and horizontally along the inside of the equipment track 1, so that the height sensor will not shake during the detection process, thereby improving the accuracy of the detection.

[0041] A movable detection mechanism 3 is provided at the bottom of the equipment track 1. The movable detection mechanism 3 includes several fixed blocks 301 fixedly connected to the bottom of the equipment track 1.

[0042] The mobile detection mechanism 3 also includes a moving rod 304 fixedly connected to the top of the moving block 303. A limiting groove 305 is opened directly above the equipment track 1. The moving rod 304 slides inside the limiting groove 305. A protective cover 306 is fixedly connected to the end of the moving rod 304 away from the moving block 303. The laser measuring instrument 16 is set inside the protective cover 306.

[0043] The mobile detection mechanism 3 also includes several push plates 307 fixedly connected to the bottom of the vehicle chassis 15. A passive rod 308 slides through the interior of the first moving block 303, and the push plates 307 press against the passive rod 308. A second moving block 309 is slidably connected to the sliding rod 302. The function of this component is that, by setting up the mobile detection mechanism 3, when the threaded sleeve 203 drives the detection platform 14 to move along the auxiliary sliding rod 206 to the vicinity of the mobile detection mechanism 3, the push plates 307 at the bottom of the vehicle chassis 15 contact the passive rod 308 on the first moving block 303. At this time, the push plates 307... 07 drives the moving block 303 on the passive rod 308 to slide along the sliding rod 302. The moving block 303 drives the moving rod 304 to slide along the limiting groove 305. The moving block 303 drives the protective cover 306 on the top of the moving rod 304 to move. At this time, the laser measuring instrument 16 inside the protective cover 306 moves synchronously with the car chassis 15 on the detection platform 14. This setting helps to ensure that several laser measuring instruments 16 and the car chassis 15 remain relatively stationary during the movement, which helps to improve the accuracy of the laser measuring instrument 16 in the device for detecting the car chassis 15.

[0044] Example 2 differs from Example 1 in that: Figure 1 - Figure 9 As shown, an adjustment mechanism 4 is provided on the movable block 303. The adjustment mechanism 4 includes a lead screw 401 rotatably connected to the side wall of the movable block 303. The movable block 309 is rotatably connected to the lead screw 401. A rotating handle 402 is fixedly connected to the end of the lead screw 401 away from the movable block 303. The function of this component is to adjust the laser measuring instrument 16 on the movable block 309 horizontally along the sliding rod 302 by rotating the rotating handle 402. This arrangement facilitates the adjustment of the laser measuring instrument 16 at different positions, thus making it suitable for the installation and testing of various automotive height sensors.

[0045] A reset mechanism 5 is provided on the passive rod 308. The reset mechanism 5 includes a reset spring 501 sleeved on the end of the sliding rod 302 near the moving block 303. A pressing rod 502 is fixedly connected to the end of the passive rod 308 away from the push plate 307. Several irregular sliding grooves 503 are opened directly above the equipment track 1. The pressing rod 502 slides inside the irregular sliding grooves 503. A linkage rod 504 is rotatably connected to the end of the pressing rod 502 away from the passive rod 308. The end of the linkage rod 504 away from the pressing rod 502 is rotatably connected to the moving rod 304. The function of this component is to reset the moving rod 308 by setting the reset mechanism 5, so that when the moving block 303 drives the moving rod 308, the pressing rod 501 can be reset. 4. When sliding along the limiting groove 305, the moving rod 304 drives the pressing rod 502 at one end of the linkage rod 504 to move along the irregular sliding groove 503. When the pressing rod 502 slides to the end away from the moving rod 304, the pressing rod 502 presses against the irregular sliding groove 503. The pressing rod 502 drives the passive rod 308 to slide outward along the moving block 303. When the pushing plate 307 disengages from the passive rod 308, the moving block 303 resets under the pressing action of the return spring 501. This setting is beneficial for several laser measuring instruments 16 to return to their initial positions, which facilitates the device to continuously detect whether the height sensor on the car chassis 15 is installed correctly.

[0046] A buffer mechanism 6 is provided on the fixed block 301. The buffer mechanism 6 includes a fixed post 601 fixedly connected to one side of the fixed block 301, a piston plate 602 fixedly connected to the end of the fixed post 601 away from the fixed block 301, and a buffer cylinder 603 fixedly connected to the side of the movable block 309 near the piston plate 602. The piston plate 602 and the buffer cylinder 603 are slidably connected. An air vent 604 is opened inside the movable block 309, and an air vent pipe 605 is fixedly connected to the movable block 309. The end of the air vent pipe 605 away from the movable block 309 is fixedly connected to the protective cover 306. A hose 606 is fixedly connected to one side of the movable block 309, and the end of the hose 606 away from the movable block 309 is fixedly connected to the movable block 303. The function of this component is to provide buffer mechanism 6 so that when the return spring 501 presses the movable block 303 to return to its original position... The first moving block 303 drives the second moving block 309 at one end of the lead screw 401 to slide and reset along the sliding rod 302. At this time, the second moving block 309 drives the buffer cylinder 603 to slide relative to the piston plate 602 on the fixed column 601. This setting helps to ensure that the laser measuring instrument 16 resets more smoothly and avoids the reset spring 501 from quickly squeezing the sliding rod 302, which would cause the laser measuring instrument 16 on the sliding rod 302 to shake violently due to inertia. At the same time, the gas squeezed by the piston plate 602 into the buffer cylinder 603 enters the vent pipe 605 through the vent hole 604. The gas in the vent pipe 605 is discharged into the protective cover 306. This setting helps to cool the laser measuring instrument 16 inside the protective cover 306 and remove dust from inside the protective cover 306, thereby ensuring the normal operation of the laser measuring instrument 16.

[0047] A vehicle height sensor installation detection device and its usage method include the following steps:

[0048] Step 1: The car chassis moves stably for 15 seconds;

[0049] Step 2: The vehicle chassis 15 and the laser measuring instrument 16 are kept relatively stationary for inspection;

[0050] Step 3: Adjust the position of the laser measuring instrument 16;

[0051] Step 4: Reset the laser measuring instrument 16 to achieve continuous detection;

[0052] Step 5: Reset the buffer of the laser measuring instrument 16.

[0053] One specific application of this embodiment is:

[0054] When using this testing equipment, firstly, the car chassis 15 is fixedly installed on the testing platform 14 directly above the sliding base 13. Then, the drive motor 201 is started. The output end of the drive motor 201 rotates, causing the output shaft 202 to rotate. The output shaft 202 rotates, causing the gear 204 to rotate. The gear 204 rotates, causing the threaded sleeve 203 on the gear ring 205 to rotate. The rotation of the threaded sleeve 203 causes the sliding base 13 on the threaded sleeve 203 to move along the threaded rod 12. The movement of the sliding base 13 causes the car chassis 15 directly above the testing platform 14 to move along the auxiliary slide rod 206. This arrangement helps the car chassis 15 to move stably and horizontally along the equipment track 1, preventing the height sensor from shaking during testing and improving testing accuracy. By setting up the moving testing mechanism 3, when the threaded sleeve 203 moves the testing platform 14 along the auxiliary slide rod 206 to the vicinity of the moving testing mechanism 3, the push plate 307 at the bottom of the car chassis 15 and the moving block 3... When the passive rod 308 on 03 comes into contact, the push plate 307 drives the moving block 303 on the passive rod 308 to slide along the sliding rod 302. The moving block 303 drives the moving rod 304 to slide along the limiting groove 305. The moving block 303 drives the protective cover 306 on the top of the moving rod 304 to move. At this time, the laser measuring instrument 16 inside the protective cover 306 moves synchronously with the car chassis 15 on the detection platform 14. This setting helps to ensure that several laser measuring instruments 16 and the car chassis 15 remain relatively stationary during the movement, which helps to improve the accuracy of the laser measuring instrument 16 in the device for detecting the car chassis 15. By setting the adjustment mechanism 4, by rotating the rotating handle 402, the rotating handle 402 drives the lead screw 401 to rotate. The rotation of the lead screw 401 drives the laser measuring instrument 16 on the moving block 309 to move horizontally along the sliding rod 302. This setting facilitates the adjustment of laser measuring instruments 16 in different positions, thus making it suitable for the installation and detection of various car height sensors.

[0055] By setting a reset mechanism 5, when the moving block 303 drives the moving rod 304 to slide along the limiting groove 305, the moving rod 304 drives the pressing rod 502 at one end of the linkage rod 504 to move along the irregular sliding groove 503. When the pressing rod 502 slides to the end away from the moving rod 304, the pressing rod 502 presses against the irregular sliding groove 503. The pressing rod 502 drives the passive rod 308 to slide outward along the moving block 303. When the push plate 307 disengages from the passive rod 308, the moving block 303 resets under the pressing action of the reset spring 501. This setting is beneficial for several laser measuring instruments 16 to return to their initial positions, facilitating the continuous detection of whether the height sensor on the car chassis 15 is installed correctly. By setting a buffer mechanism 6, when the reset spring 501 presses the moving block 303 to reset, the moving block 303... Block 1 303 drives the movable block 2 309 at one end of the lead screw 401 to slide and reset along the sliding rod 302. At this time, the movable block 2 309 drives the buffer cylinder 603 to slide relative to the piston plate 602 on the fixed column 601. This setting helps to ensure that the laser measuring instrument 16 resets more smoothly and avoids the reset spring 501 from quickly squeezing the sliding rod 302, which would cause the laser measuring instrument 16 on the sliding rod 302 to shake violently due to inertia. At the same time, the gas squeezed by the piston plate 602 into the buffer cylinder 603 enters the vent pipe 605 through the vent hole 604. The gas in the vent pipe 605 is discharged into the protective cover 306. This setting helps to cool the laser measuring instrument 16 inside the protective cover 306 and remove dust from inside the protective cover 306, thereby ensuring the normal operation of the laser measuring instrument 16.
