[0002] When a car is undergoing a corrosion resistance test, various corrosion environments that the vehicle may encounter during actual use will be simulated so as to better assess the corrosion resistance of the entire vehicle.

[0003] During actual testing, the car needs to be subjected to multiple cycle tests. After each cycle test, the corrosion condition of the vehicle is checked. A system inspection is performed every 10 cycles to determine the corrosion level.

[0004] Every time the corrosion of the vehicle is checked, the staff is required to take pictures of the key areas, measure and record information, and then compare and analyze the data, which increases the workload of the staff. In addition, the number of cycles of the vehicle corrosion test is relatively large. If the vehicle is interrupted from the corrosion test after each cycle to manually record the data, the corrosion test cycle of the entire vehicle will be extended, which will have a certain impact on the vehicle's anti-corrosion process. When monitoring the data of the vehicle body, in order to reduce the workload of the staff, multiple monitoring devices are often fixed on the vehicle body to carry out real-time monitoring of the parts that need to be monitored. However, due to the different sizes and structures of the test vehicles, and the need for the vehicle to travel in a specific environment during the test, there is an urgent need for a corrosion test device that can remotely monitor and obtain vehicle body corrosion data and is suitable for different test vehicles and can maintain the stability of the monitoring equipment.

[0056] like Figure 5 As shown, the mounting base 34 includes a base plate 341 inserted into the two positioning assemblies 33, one end of the base plate 341 is clamped with a movable bracket 342, the top of the movable bracket 342 is slidably connected with a positioning plate 343, the end of the positioning plate 343 away from the movable bracket 342 is fixedly connected with a fixed bracket 344, the fixed bracket 344 is clamped at the end of the base plate 341 away from the movable bracket 342, so that the positioning plate 343 can be clamped and fixed on the base plate 341 through the movable bracket 342 and the fixed bracket 344, and has more convenient installation and disassembly conditions, the movable bracket 342 is fixedly connected with a fixing cylinder 345, the fixing cylinder 345 is threadedly connected with a threaded rod 346, the end of the threaded rod 346 away from the fixing cylinder 345 is rotatably connected to the fixed bracket 344, and the threaded rod 346 can only rotate on the fixed bracket 344, so that the movable bracket 342 and the fixed bracket 344 can be firmly clamped on the base plate 341 through the rotation of the threaded rod 346.

[0059] The monitoring probe 4 is fixed to the top plate 348 .

[0060] In addition, according to an embodiment of the present application, a corrosion resistance test device for obtaining vehicle body corrosion data based on remote monitoring also has the following additional technical features:

[0061] like Figure 2 and Figure 4 As shown, the vacuum suction cup 31 is adjusted and fixed on the slide bar 32 by means of a positioning assembly 33 , so that the vacuum suction cup 31 and the slide bar 32 have sliding and fixing capabilities.

[0062] Furthermore, the positioning assembly 33 includes an upper chuck 331 sliding on the sliding rod 32, and a lower chuck 332 sliding on the sliding rod 32, and a bolt 333 is threadedly connected between the upper chuck 331 and the lower chuck 332, and the upper chuck 331 and the lower chuck 332 can be fixed to the sliding rod 32 by the bolt 333, and the tightness of the upper chuck 331 and the lower chuck 332 on the sliding rod 32 can be changed by the tightening action of the bolt 333, so as to facilitate the displacement or fixation of the upper chuck 331 and the lower chuck 332 on the sliding rod 32.

[0063] Among them, the sliding rod 32, the upper chuck 331, the lower chuck 332 and the bolt 333 are all made of non-metallic corrosion-resistant materials.

[0065] Further, such as Figure 5 As shown, flanges are symmetrically provided at both ends of the bottom plate 341 , and the flanges are matched with the positioning grooves 334 , so that the bottom plate 341 is plugged and fixed between the two symmetrical upper chucks 331 .

[0068] Furthermore, a T-shaped block is provided at the top of the movable bracket 342 , and a T-shaped slide groove is provided at the bottom side of the positioning plate 343 . The T-shaped block on the movable bracket 342 and the T-shaped slide groove on the positioning plate 343 are adapted to each other.

[0069] Furthermore, the threaded rod 346 and the fixing tube 345 are made of non-metallic corrosion-resistant material. In the embodiment of the present application, plastic products or electroplated parts can be used to prevent the parts from rusting during the corrosion resistance test.

[0070] The following describes the use process of a corrosion resistance test device for obtaining vehicle body corrosion data based on remote monitoring according to an embodiment of the present application with reference to the accompanying drawings:

[0071] In the embodiment of the present application, the monitoring of the rust condition of the test sample 2 is described as an example. The test sample 2 is fixed (by gluing or other methods) on the hood of the vehicle, and then the vacuum suction cup 31 is adjusted to a good position on the slide bar 32. The entire support mechanism 3 is fixed to the hood by the vacuum suction cup 31, so that the monitoring probe 4 thereon can monitor the surface changes of the test sample 2 in real time. Specifically, the movable bracket 342 and the positioning plate 343 are plugged in, and the positioning plate 343 is clamped on the bottom plate 341 by the movable bracket 342 and the fixed bracket 344. Then, the upper chuck 331 and the lower chuck 332 on the slide bar 32 are changed in tightness by rotating the bolt 333, and the bottom plate 341 is plugged in between the two upper chucks. The upper chuck 331 and the lower chuck 332 are fixed to the slide bar 32 by bolts 333, and the angle of the top plate 348 on the positioning plate 343 is adjusted by the telescopic change of the first telescopic member 349, so that the monitoring range of the monitoring probe 4 on the top plate 348 covers the test sample 2, and then in the specific test process, the real-time data of the test sample 2 is continuously fed back to the signal analysis system through the monitoring probe 4, and the data is analyzed and compared to determine which test sample 2 has better corrosion resistance. Specifically, lines of the same size and depth can be drawn on multiple different test samples 2, according to the standard QC / T 732-2005 "Passenger Car Strengthening Corrosion Test Method", the test intensity adopts a corrosion rate of 70μm / a and a test load of 60%, to simulate the various corrosion environments that may be encountered in actual use of the vehicle for monitoring, and the data of the test sample 2 is monitored in the embodiment of the present application.

[0072] In the related art, for a corrosion resistance test device that obtains vehicle body corrosion data based on remote monitoring, when performing a corrosion resistance test on the vehicle body, a salt spray test needs to be carried out on the vehicle body. The vehicle is placed in a salt spray test chamber to artificially create a salt spray environment to monitor the quality of the salt spray corrosion resistance performance of the vehicle body. When the salt spray is sprayed onto the vehicle body, it will inevitably be sprayed onto the monitoring probe 4, causing the monitoring end of the monitoring probe 4 to be covered with water mist, affecting the monitoring of the test sample 2 by the monitoring probe 4.

[0073] According to some embodiments of the present application, as Figure 6 and Figure 7 shown, a descaling mechanism 5 is provided at the monitoring end of the monitoring probe 4. The descaling mechanism 5 includes a rotating ring 51 that is limitedly rotatably connected to the monitoring probe 4. Specifically, the rotating ring 51 can only rotate on the monitoring probe 4 and cannot undergo axial displacement, and a motor 52 fixed to the monitoring probe 4. The motor 52 provides the power for the rotating ring 51 to rotate, so that the rotating ring 51 can rotate on the monitoring probe 4. A scraping blade 53 is inserted into the rotating ring 51 in a limited manner. The scraping blades 53 are arranged in a circumferential array along the rotating ring 51, and the scraping blades 53 are in contact with the monitoring end of the monitoring probe 4.

[0074] Among them, a limiting block 511 is fixedly connected to the side of the rotating ring 51 away from the monitoring probe 4. The limiting block 511 is arranged in a U shape, and both ends of the U-shaped limiting block 511 are fixedly connected to the rotating ring 51.

[0075] It should be noted that the limiting block 511 is designed in a U shape, so that there is a through hole between the limiting block 511 and the rotating ring 51. Then, during the scraping process, the liquid or other substances scraped off from the monitoring probe 4 can脱离 from the through hole, avoiding the accumulation of scraping substances on the monitoring probe 4.

[0076] Furthermore, a driving gear 521 is key-connected to the output end of the motor 52. A driving ring gear 522 is engaged with one side of the driving gear 521. The driving ring gear 522 is fixedly sleeved on the rotating ring 51. In this way, the motor 52 can drive the driving gear 521 to drive the driving ring gear 522 to rotate, and then the rotating ring 51 rotates synchronously. It should be noted that the rotating ring 51 and the monitoring end of the monitoring probe 4 are coaxial.

[0077] Furthermore, a scraping strip 531 that is in contact with the monitoring end of the monitoring probe 4 is provided on the scraping blade 53. A limiting groove 532 is provided on the scraping blade 53. The scraping strip 531 and the limiting groove 532 are slidably inserted and matched. The insertion method facilitates the replacement of the scraping strip 531, and the rotating rotating ring 51 can scrape the monitoring end surface of the monitoring probe 4 through the scraping strip 531.

[0078] It should be noted that as Figure 3 、 Figure 6As shown, the plug-in direction of the scraping leaf 53 does not point to the center of the swivel 51, but is plugged in obliquely to the center of the swivel 51. In the embodiment of the present application, three scraping leaves 53 are taken as an example. After the three scraping leaves 53 are plugged into the swivel 51, the ends thereof close to the center of the swivel 51 all pass over the center of the swivel 51. In this way, the three scraping leaves 53 will scrape the monitoring end face of the monitoring probe 4 in all directions when following the rotation of the swivel 51, and the three scraping leaves 53 will not cause continuous obstruction to the monitoring end when scraping the monitoring probe 4, so as to avoid affecting the monitoring result of the monitoring probe 4.

[0079] Therefore, during specific use, when the vehicle body enters a salt spray test or a test in a humid environment, the motor 52 is started, and the active gear ring 522 is driven by the active gear 521 to drive the swivel 51 to rotate, and then the scraping blade 53 is driven to rotate, so that the scraping strip 531 on the scraping blade 53 can scrape the monitoring end face of the monitoring probe 4, avoiding the formation of water mist on the monitoring end or salt stains and other dirt left after the salt mist dries, which affects the data monitoring of the test sample 2 by the monitoring probe 4.

[0080] In the related art, the corrosion resistance testing device for obtaining vehicle body corrosion data based on remote monitoring needs to perform a high-temperature and high-humidity storage test on the vehicle body during the corrosion resistance test. The monitoring probe 4 will generate a certain amount of heat due to its own work. In a high-temperature and high-humidity environment, the heat of the monitoring probe 4 is more difficult to dissipate, which can easily cause the internal temperature of the monitoring probe 4 to rise sharply, causing the monitoring probe 4 to lose its monitoring function due to excessive temperature.

[0081] According to some embodiments of the present application, Figure 8-Figure 12 As shown, the monitoring end of the monitoring probe 4 is also provided with an auxiliary mechanism 6, which includes a driven ring 61 rotatably connected to one side of the rotating ring 51, and a power component 62 is transmission-connected to the driven ring 61, and the power component 62 is fixedly connected to the limit block 511. The power component 62 and the scraping leaf 53 are transmission-connected, and a second telescopic member 63 is fixedly connected to the monitoring probe 4, and the telescopic end of the second telescopic member 63 cooperates with the driven ring 61.

[0082] It should be noted that the second telescopic member 63 can be an existing technology with a telescopic function such as an electric push rod. It should be further noted that in the embodiment of the present application, the second telescopic member 63 can be made of plastic or electroplated products to prevent damage to the second telescopic member 63 during the corrosion resistance test.

[0083] Further, such as Figure 7 As shown, the scraping blade 53 is arranged in a paddle shape, and a tooth plate 533 is fixedly connected to the side wall of the scraping blade 53.

[0084] Among them, the driven ring 61 includes a power ring 611 and a locking ring 612 coaxially fixed together, wherein the locking ring 612 and the swivel ring 51 are rotatably connected (it should be noted that a T-ring can be added on the side wall of the locking ring 612, and a T-ring groove can be added on the side wall of the swivel ring 51, wherein the T-ring and the T-ring groove are coaxial, and the T-ring fits along the axial clearance in the T-ring groove, so that the driven ring 61 has axial displacement capability on the swivel ring 51), a power groove 613 is coaxially arranged on the side of the power ring 611 away from the locking ring 612, and a clamping groove 614 is coaxially arranged on the side of the locking ring 612 away from the power ring 611.

[0085] It should be noted that the two adjacent side walls of the locking ring 612 and the rotating ring 51 are designed to increase the friction force. Specifically, the two side walls can be designed with non-smooth surfaces.

[0086] Furthermore, the power assembly 62 includes a support rod 621 fixed to the limit block 511, the support rod 621 is connected to the upper limit rotation with a rotating shaft 622, and the two ends of the rotating shaft 622 are key-connected with a driven roller 623 and a driven gear 624 respectively;

[0087] like Fig.12 As shown, the driven roller 623 and the power groove 613 are clearance-matched, and the driven gear 624 and the tooth plate 533 are meshed.

[0088] Specifically, the open end of the power groove 613 is of semi-closed design, wherein the diameter of the driven roller 623 is smaller than the radial width of the power groove 613, the thickness of the driven roller 623 is smaller than the axial width of the power groove 613, and the driven roller 623 and the semi-closed open end of the power groove 613 are frictionally abutted against one side facing the center of the circle.

[0089] It should be noted that the axial distance between the driven roller 623 and the side wall of the open end of the power groove 613 is the same as the axial displacement distance of the driven ring 61 on the rotating ring 51, that is, when the driven ring 61 is axially displaced, a friction abutment relationship can be formed or broken between the driven roller 623 and the semi-closed open end of the power groove 613 facing the center of the circle.

[0090] Furthermore, the telescopic end of the second telescopic member 63 is rotatably connected to a clamping block 631 , and the clamping block 631 is located in the clamping groove 614 , and the clamping block 631 and the clamping groove 614 are clearance-matched.

[0091] It should be noted that if Fig.12 As shown, the radial cross section of the clamping groove 614 is T-shaped, and the clamping block 631 is Fig.12 Only one end (lower or upper part) of the right opening end of the clamping groove 614 can form an abutment relationship.

[0092] It can be understood that when the telescopic end of the second telescopic member 63 contracts, the clamping block 631 will be pulled so that the clamping block 631 abuts against the open end of the clamping groove 614, and continues to drive the entire driven ring 61 to abut against the rotating ring 51, and then under the action of axial pressure, the driven ring 61 can be driven to rotate when the rotating ring 51 rotates, and because the clamping block 631 and the telescopic end of the second telescopic member 63 are rotatably connected, when the driven ring 61 rotates, the axial force between the clamping block 631 and the clamping groove 614 will not affect the rotation of the driven ring 61, and at the same time, when the driven ring 61 undergoes axial displacement, a friction abutment relationship will be formed between the semi-closed open end of the power groove 613 facing the center of the circle and the driven roller 623, and then when the driven ring 61 rotates, the driven roller 623 will be driven to rotate accordingly.

[0093] It should be noted that the motor 52 has forward and reverse rotation functions.

[0094] Therefore, when in use, the clamping block 631 can be pulled back to abut the right open end of the clamping groove 614 by the backward contraction of the telescopic end of the second telescopic member 63, and the entire driven ring 61 can be driven to abut against the rotating ring 51 through this axial force. At the same time, a friction abutment relationship is formed between the semi-closed open end of the power groove 613 on the driven ring 61 facing the center of the circle and the driven roller 623. Because the locking ring 612 and the rotating ring 51 and the two adjacent side walls of the driven roller 623 and the power groove 613 are designed to increase the friction force, when the starting motor 52 drives the rotating ring 51 to rotate, the driven ring 61 can be synchronously driven to follow the rotation. At this time, under the rotation of the driven ring 61, the power groove 613 thereon will drive the driven ring 61 to rotate during the rotation process. The driven roller 623 rotates, and then drives the rotating shaft 622 and the driven gear 624 thereon to rotate synchronously. When the driven gear 624 rotates, it drives the corresponding scraping leaf 53 to move on the limit block 511 through the tooth plate 533 meshing with it. It can be understood that the scraping leaf 53 can move from the limit block 511 to a position away from the center of the rotating ring 51, that is, the scraping leaf 53 is in an expanded state on the monitoring probe 4. After the scraping leaf 53 forms the expanded state, the second telescopic member 63 is telescopically changed, so that the clamping block 631 loses the axial force provided to the clamping groove 614, and the axial force between the driven ring 61 and the rotating ring 51 is lost, that is, the rotating ring 51 loses the friction force that can drive the driven ring 61 to rotate. Then, when the rotating ring 51 rotates at this time, the driven ring 61 will no longer rotate with the rotating ring 51. At the same time, due to the reverse displacement of the driven ring 61, the friction abutment relationship between the driven roller 623 and the semi-closed open end of the power groove 613 facing the center of the circle is disconnected. Then, when the rotating ring 51 drives the scraping blade 53 to rotate at this time, the driven roller 623 will follow the rotating ring 51 to rotate around the axis of the rotating ring 51. However, the driven roller 623 is disconnected from the power groove 613 at this time, so the driven roller 623 will not rotate on its own. Then, when the rotating ring 51 drives the scraping blade 53 to rotate at this time, an airflow will be formed during the rotation process through the scraping blade 53 arranged in the shape of a paddle. The flow of the airflow will help to monitor The heat dissipation on the surface of the monitoring probe 4 further helps the monitoring probe 4 to dissipate the heat accumulated inside itself to the surrounding environment in a high temperature and high humidity environment, and avoids the internal heat accumulation caused by the high temperature of the surrounding environment as much as possible, causing the temperature to rise and affect normal use. At the same time, due to the high humidity in the use environment, in the embodiment of the present application, the scraping leaf 53 can be driven to retract toward the monitoring end of the monitoring probe 4 through the reverse rotation of the motor 52 and the reverse extension of the second telescopic member 63, and the rotating ring 51 can be driven to rotate by the motor 52 alone, so that the scraping leaf 53 completes the scraping of the monitoring end face of the monitoring probe 4, avoiding the formation of water mist on the monitoring end face of the monitoring probe 4 and affecting its normal work. This design allows the descaling mechanism 5 and the auxiliary mechanism 6 to cooperate with each other.The position of the scraping blade 53 on the limit block 511 can be changed to scrape the monitoring end surface of the monitoring probe 4, and an airflow can be formed around the monitoring probe 4 to help the monitoring probe 4 keep the internal heat from increasing.
