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] Currently, existing calibration devices for smart dashboards on the market have many limitations. When calibrating and testing smart dashboards, most rely on manual connection of the calibrator's socket to the car dashboard plug. This manual operation is not only inefficient, but also difficult to ensure the consistency and accuracy of each connection. At the same time, manual connection is difficult to achieve multiple back-and-forth plugging of the calibrator's socket and the car dashboard plug, making it difficult to conduct comprehensive and repeated testing of the dashboard, and thus unable to accurately determine the dashboard's performance under different connection states.

[0003] In addition, 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 device cannot quickly and accurately detect the sensitivity of the plug. As a result, 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] The Chinese patent (publication number CN111006707A) discloses a calibration device for an automobile instrument panel, comprising a base, wherein the four sides of the bottom surface of the base are fixedly connected with lifting pillars, a receiving groove is provided in the middle of the base, and an openable bottom cover is symmetrically provided at the bottom of the receiving groove. 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 spaced and 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 provided on the inner wall of the fixing ring in combination with the clamping ring, thereby avoiding shaking of the instrument panel during the calibration process and ensuring the accuracy of the actual calibration result. Moreover, the matching of the sliding groove and the sliding rod facilitates the adjustment and change of 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 position of the car dashboard. Although it has the angle adjustment function, 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 perform multiple comprehensive inspections. This greatly limits the application effect and accuracy of the scheme in the calibration work, making it seem powerless in the face of complex calibration requirements. For this reason, we propose a calibration device and usage method for a smart dashboard. Summary of the Invention

[0037] The upper end of each mating plate 10 is slidably connected to two first moving blocks 24 with a reset function, and the two first moving blocks 24 are symmetrically distributed on the upper end of the mating plate 10.

Even if it is compressed and deformed multiple times, it can quickly return to its original shape.

[0039] See also Figures 4 to 8 The plug-in mechanism 301 includes a vent box 31, which is fixedly connected to the upper end of the mating plate 10. The vent box 31 is fixedly connected to the adjacent second shrink sleeve 25 through a vent pipe 42. The inner wall of the vent box 31 is also slidably connected to a block 44 with a reset function, and the outer wall of the block 44 abuts against the outer wall of the vent pipe 42. A reset elastic telescopic rod 43 is fixedly connected between the bottom of the block 44 and the bottom end of the inner wall of the vent box 31. The reset elastic telescopic rod 43 can quickly reset the block 44. The upper end of the block 44 is also fixedly connected to the abutting arm 30, and the upper end of the abutting arm 30 is also rotatably connected to the second rotating wheel 29 through a rotating shaft.

[0040] The upper end of the mating plate 10 is also slidably connected to a second moving block 37. Specifically, the upper end of the mating plate 10 is fixedly connected to two slide bars 38. The two slide bars 38 are symmetrically distributed on the upper end of the mating plate 10. The second moving block 37 is slidably connected to the outer walls of the two slide bars 38. The bottom of the second moving block 37 is fixedly connected to two moving arms 32 (such as Figure 5 As shown), a second curved block 45 is fixedly connected to the outer wall of each movable arm 32, and the upper end of the second curved block 45 is rotatably connected to the first curved block 33 with a reset function, and a first reset torsion spring is fixedly connected between the first curved block 33 and the second curved block 45, and the upper end of the matching plate 10 is rotatably connected to a recovery wheel 39 with a reset function through a rotating shaft, and a second reset torsion spring is fixedly connected between the recovery wheel 39 and the matching plate 10, and the recovery wheel 39 is located below the second movable block 37, and a pull rope 40 is wound around the outer wall of the recovery wheel 39, and the free end of the pull rope 40 is fixedly connected to the outer wall of the third shrink sleeve 41, and the upper end of the matching plate 10 is also fixedly connected to a limiting block 46, and the outer wall of the pull rope 40 abuts against the outer wall of the limiting block 46, and the limiting block 46 can guide the pull rope 40;

[0041] The upper end of the recovery wheel 39 is fixedly connected to a turntable 34, and a plurality of weight-reducing holes are provided on the outer wall of the turntable 34. The plurality of weight-reducing holes are distributed circumferentially on the outer wall of the turntable 34.

The upper end of the second mounting bracket 7 is fixedly connected to the second matching arm 22, and the front end of the second mounting bracket 7 is fixedly connected to the first matching arm 21. The second matching arm 22 and the first matching arm 21 are both adapted to the second rotating wheel 29 (as shown in FIG. Figure 4 As shown in the figure), when the turntable 34 rotates, the turntable 34 drives 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 moves back and forth on the outer wall of the slide rod 38. The second moving block 37 drives 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.

[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 just 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. 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 shrinking sleeves 13 to rotate through the rectangular box 15. The first shrinking sleeve 13 abuts against the inner wall of the arc strip 14 through the first rotating wheel 12. When the first shrinking sleeve 13 shrinks, the internal gas enters the corresponding second shrinking sleeve 25. At this time, the two second shrinking sleeves 25 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 abutting arm 30. When the blocking block 44 is separated from the abutting against the outer wall of the ventilation pipe 42, the gas inside the first shrinking sleeve 13 will enter the third shrinking 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 will be 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 cooperating arm 21, the resetting elastic telescopic rod 43 resets the block 44, and the block 44 blocks the vent pipe 42. At this time, the third rotating wheel 5 continues to rotate. When the second rotating wheel 29 is in contact with the second cooperating arm 22, the block 44 will be out of contact with the vent pipe 42, and the third shrinking sleeve 41 will be reset. At this time, the third shrinking sleeve 41 will release the pull rope 40 when it shrinks, and the recovery wheel 39 will recycle the pull rope 40 when it resets and rotates. At the same time, the first rotating wheel 12 Having broken away from the contact with the inner wall of the arc-shaped strip 14, 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 shrink, they drive the two first moving blocks 24 to move in opposite directions. At this time, the two abutment plates 23 will break away from the contact with the outer wall of the car instrument panel, and the car instrument panel can be taken out, and then a new car instrument panel can be fixed. According to the above working principle, it can be seen that the new car instrument panel can be tested.

[0046] It is worth noting that when the second rotating wheel 29 disengages from the outer wall of the first cooperating arm 21, the second movable block 37 will drive the plug fixed on the car dashboard to disengage from the socket 9, 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 embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.

2. A method for using a calibration device for a smart instrument panel, applied to the calibration device for a smart instrument panel as claimed in claim 1, characterized in that: The following steps are involved: S1: Place the car instrument panel on the upper end of the matching plate (10), 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. Start the driving motor (4) to drive the second pulley (19) to rotate. The second pulley (19) drives the first pulley (17) to rotate through the transmission belt (18). The first pulley (17) drives the third rotating wheel (5) to rotate. When the third rotating wheel (5) rotates, The third rotating wheel (5) drives all the first shrinking sleeves (13) to rotate through the rectangular box (15). The first shrinking sleeves (13) abut against the inner wall of the arc strip (14) through the first rotating wheel (12). When the first shrinking sleeves (13) shrink, the gas inside enters the corresponding second shrinking sleeves (25). At this time, the extension of the two second shrinking sleeves (25) drives the two first moving blocks (24) to move in opposite directions. The two first moving blocks (24) drive the first elastic telescopic rod (28) and the abutting plate (23) to clamp and fix the car instrument panel. S2: When the second shrink sleeve (25) cannot be extended, the gas inside the first shrink sleeve (13) will be squeezed inside, and the air pressure inside the first shrink sleeve (13) will increase. When the second rotating wheel (29) abuts against the first matching arm (21), the abutting arm (30) will drive the ventilation box (31) to break away from the abutment with the outer wall of the ventilation pipe (42), and the gas inside the first shrink sleeve (13) will enter the third shrink sleeve (41) through the ventilation box (31). The third shrink sleeve (41) is extended to the pull rope (40 ) is pulled, the third shrink sleeve (41) drives the recovery wheel (39) and the turntable (34) to rotate simultaneously, the turntable (34) moves the moving rod (35) back and forth in the inner wall of the slide groove (36), the second moving block (37) drives the two moving arms (32) to move back and forth, and the moving arms (32) drive the clamped plug to be plugged back and forth with the corresponding socket (9), when the second rotating wheel (29) is disengaged from the outer wall of the first matching arm (21), the blocking block (44) will reset to block the vent pipe (42); S3: When the second rotating wheel (29) abuts against the outer wall of the second matching arm (22), the blocking block (44) is again disengaged from the abutment with the outer wall of the vent pipe (42), and the first rotating wheel (12) is disengaged from the abutment with the inner wall of the arc strip (14). When the first shrinking sleeve (13) is reset, the first shrinking sleeve (13) will suck the second shrinking sleeve (25) and the third shrinking sleeve (41) connected together. The reset of the third shrinking sleeve (41) will release the pull rope (40), and the recovery wheel (39) drives the turntable (34) to reset and rotate. When the two second shrinking sleeves (25) are retracted, they will drive the first moving block (24) to reset. When the abutting plate (23) is disengaged from the abutment with the outer wall of the car dashboard, the housing takes the car dashboard.
