Description

Technical Field

[0001] The present invention relates to the technical field of instrument calibration, and in particular to a calibration device for an intelligent instrument panel and a use method thereof. Background Art

[0002] At present, the existing calibration devices for smart dashboards on the market have many limitations. When calibrating and testing smart dashboards, most of them rely on manual connection of the calibrator's socket with the plug of the car dashboard. This manual operation method is not only inefficient, but also difficult to ensure the consistency and accuracy of each connection. At the same time, it is difficult to manually connect the calibrator's socket with the plug of the car dashboard many times, making it difficult to comprehensively and repeatedly test the dashboard, and thus it is impossible to accurately judge the performance of the dashboard under different connection states.

[0003] In addition, the existing calibration devices lack effective means to detect the sensitivity of the plug. The sensitivity of the plug directly affects the stability and accuracy of data transmission between the instrument panel and the calibrator. If the plug sensitivity is poor, it may cause deviations in the calibration data, thereby affecting the calibration accuracy of the entire smart instrument panel. However, the existing calibration devices cannot quickly and accurately detect the sensitivity of the plug, so that after the smart instrument panel is put into use, it may display abnormal data due to plug problems, posing potential safety hazards to the driver.

[0004] A Chinese patent (publication number CN111006707A) discloses a calibration device for an automobile instrument panel, comprising a base, wherein the bottom surface of the base is fixedly connected with lifting pillars around, a receiving groove is provided in the middle of the base, and a bottom cover that can be opened and closed is symmetrically arranged at the bottom of the receiving groove, and a lock is also provided in the middle of the bottom cover, and a sliding groove is provided in the middle of the side wall of the receiving groove, and two sliding rods are symmetrically slidably arranged in the sliding groove, and the ends of the two sliding rods are fixedly connected with a fixing ring, and the inner wall of the fixing ring is evenly fixedly connected with a plurality of telescopic springs. The calibration device for the automobile instrument panel can directly clamp and fix the instrument panel by using the fixing ring and the telescopic springs arranged on the inner wall of the fixing ring in combination with the clamping ring, so as to avoid the shaking of the instrument panel during the calibration process and ensure the accuracy of the actual calibration result, and through the matching of the sliding groove and the sliding rod, it is convenient to adjust and change the calibration equipment during the calibration process, which brings great convenience to the calibration work.

[0005] According to the above scheme, it can be seen that the above scheme can only fix the limit of the car dashboard. Although it has the function of angle adjustment, it has obvious shortcomings. It cannot realize the repeated plugging and unplugging between the plug of the car dashboard and the socket of the calibrator, which makes it difficult to conduct multiple comprehensive inspections. This greatly limits the application effect and accuracy of the scheme in the calibration work, making it incapable of meeting complex calibration requirements. For this reason, we propose a calibration device and a method for use of a smart dashboard. Summary of the invention

The second moving block 37 will drive the two moving arms 32 to move back and forth, so that the car dashboard plug clamped by the first curved block 33 and the second curved block 45 can be plugged back and forth with the corresponding socket 9.

[0042] The working principle of the present invention is:

[0043] When the present invention is used, it is only necessary to place the car instrument panel on the upper end of the matching plate 10 directly above the third rotating wheel 5, and then place the docking plug of the car instrument panel between the corresponding first curved block 33 and the second curved block 45. The first curved block 33 and the second curved block 45 are closed to clamp the plug, and the driving motor 4 is started to drive the second pulley 19 to rotate, and the second pulley 19 drives the first pulley 17 to rotate through the transmission belt 18, and the first pulley 17 drives the third rotating wheel 5 to rotate. When the third rotating wheel 5 rotates, the third rotating wheel 5 will drive all the first shrink sleeves 13 to rotate through the rectangular box 15, and the first shrink sleeve 13 is mutually abutted against the inner wall of the arc strip 14 through the first rotating wheel 12. When the first shrink sleeve 13 shrinks, the internal gas enters the corresponding second shrink sleeve 25, and at this time, the two second shrink sleeves 25 The extension will drive the two first moving blocks 24 to move in opposite directions, and the two first moving blocks 24 drive the first elastic telescopic rod 28 and the abutment plate 23 to clamp and fix the automobile instrument panel. When the second shrink sleeve 25 cannot be extended, the gas pressure inside the first shrink sleeve 13 becomes larger. When the second rotating wheel 29 and the first matching arm 21 abut against each other, the third rotating wheel 5 needs to stop rotating. The second rotating wheel 29 drives the blocking block 44 to move toward the bottom end of the inner wall of the ventilation box 31 through the abutment arm 30. When the blocking block 44 is separated from the abutment with the outer wall of the ventilation pipe 42, the gas inside the first shrink sleeve 13 will enter the third shrink sleeve 41 through the ventilation box 31. It is worth noting that when the second rotating wheel 29 and the first matching arm 21 abut against each other, the plugs located between the first curved block 33 and the second curved block 45 are all facing the corresponding sockets 9.

[0044] When the third shrink sleeve 41 is extended, the third shrink sleeve 41 will pull the pull rope 40, and the pull rope 40 will pull and rotate the recovery wheel 39, and the recovery wheel 39 will drive the turntable 34 to rotate, and the turntable 34 will drive the moving rod 35 to move back and forth in the inner wall of the slide groove 36. At this time, the second moving block 37 will move back and forth on the outer wall of the slide rod 38, and the second moving block 37 will drive the two moving arms 32 to move back and forth, so that the car instrument panel plug clamped by the first curved block 33 and the second curved block 45 is plugged back and forth with the corresponding socket 9. Whenever the car instrument panel plug is plugged with the corresponding socket 9, the calibrator 2 will immediately calibrate and detect the car instrument panel;

[0045] When the second rotating wheel 29 is out of contact with the first matching arm 21, the resetting elastic telescopic rod 43 resets the block 44, and the block 44 blocks the vent 42. At this time, the third rotating wheel 5 continues to rotate. When the second rotating wheel 29 is in contact with the second matching arm 22, the block 44 will be out of contact with the vent 42, and the third shrink sleeve 41 will be reset. At this time, the third shrink sleeve 41 will release the pull rope 40 when it shrinks, and the recovery wheel 39 will recover the pull rope 40 when it is reset and rotated. At the same time, the first rotating wheel 12 The contact with the inner wall of the arc strip 14 has been separated, and the corresponding first shrink sleeve 13 is reset to recover the gas inside the third shrink sleeve 41 and the second shrink sleeve 25. When the two second shrink sleeves 25 are contracted, the two first moving blocks 24 are driven to move in opposite directions. At this time, the two abutment plates 23 are separated from the abutment with the outer wall of the car dashboard, and the car dashboard can be taken out, and then a new car dashboard can be fixed. According to the above working principle, it can be known that the new car dashboard can be tested;

[0046] It is worth noting that when the second rotating wheel 29 is disengaged from the outer wall of the first mating arm 21, the second movable block 37 will drive the plug fixed on the car dashboard to disengage from the socket 9, thereby preventing the third rotating wheel 5 from rotating and causing damage to the connection between the plug and the socket 9.

[0047] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
