Description

Technical Field

[0001] This invention relates to the field of instrument testing technology, specifically to an automotive instrument testing kit and testing method. Background Technology

[0002] Before leaving the factory, vehicle instrument panels undergo surface inspection, primarily checking for damage to all displays, including but not limited to the LCD screen. This is typically done using a computer vision inspection system. The system takes photos of the instrument panel surface and sends the images to a computer system, which automatically analyzes the images to determine if the instrument panel's appearance is up to standard. Alternatively, existing AI image recognition technology can be used to automatically verify consistency between the instrument panel display and actual input torque or rotational speed, for example, whether the pointer position corresponds to the actual torque or rotational speed, thus determining the instrument panel's performance.

[0003] For example, existing patent CN113624773B discloses a vehicle instrument panel detection device that eliminates the blind spots caused by traditional CCD camera components during shooting and eliminates the need for manual flipping of the vehicle instrument panel, thus boasting high efficiency and solving the problem of low efficiency in existing vehicle instrument panel detection devices. However, it cannot clean the LCD screen while the vehicle instrument panel is placed in the detection chamber. In reality, we know that dust or foreign objects inevitably adhere to the surface of the vehicle instrument panel during testing. If it is placed directly into the detection chamber, these dust or foreign objects will also be captured in the image during camera photography, interfering with the computer's image recognition and affecting the device's judgment on whether the vehicle instrument panel is qualified. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing an automotive instrument panel testing box to solve the problem that the accuracy of testing is affected by dust and other contaminants on the surface of the instrument panel display during the testing of automotive instruments.

[0005] The technical solution of the present invention: To achieve the above objectives, the present invention provides an automotive instrument testing box, including a testing box body. A support plate is slidably connected to the inner bottom wall of the testing box body. A cleaning mechanism is provided inside the testing box body. The cleaning mechanism includes two rotating shafts, two racks (first, second, and third). Both rotating shafts are vertically rotatably connected to the inner bottom wall of the testing box body. Gears (first and second) are fixedly connected to the bottom ends of both rotating shafts, and gears (second and third) are fixedly connected to the top ends of both rotating shafts. Two connecting rods are fixedly connected to the upper surfaces of both racks (third and fourth). Each connecting rod is slidably connected to the inner top wall of the testing box body. A crossbar is rotatably connected between the two racks (third and fourth). Symmetrical gears (third and fourth) are fixedly connected to both ends of the crossbar. A cleaning sleeve is fixedly connected to the outer surface of the crossbar. A placement plate is provided inside the testing box body, and a symmetrical fixing mechanism is provided inside the testing box body.

[0006] Furthermore, both racks are fixedly connected to the outer surface of the support plate. As the support plate moves, the racks move. The gear meshes with the racks, and as the racks move, the gear rotates.

[0007] Furthermore, both racks are fixedly connected to the upper surface of the support plate, and the gear meshes with the racks. As the support plate moves, the racks move, and as the racks move, the gear rotates.

[0008] Furthermore, the fixing mechanism includes a clamping plate, on the outer surface of which are fixedly connected symmetrical sliding rods. The outer surfaces of the two sliding rods are slidably connected to fixed cylinders. The sliding rods can slide on the inner wall of the fixed cylinders, and the frictional resistance between the sliding rods and the fixed cylinders is small.

[0009] Furthermore, both of the fixed cylinders are fixedly connected to the inner wall of the bearing plate, and springs are fixedly connected to the inner walls of both fixed cylinders. The sliding rod is fixedly connected to the spring. By setting the spring, it can play a reset role. As the sliding rod slides outward, it can drive the spring to stretch.

[0010] Furthermore, a transmission rod is hinged to the bottom surface of each of the two sliding rods, and each transmission rod is hinged to the placement plate. The upper surface of the placement plate is provided with a vehicle instrument body. The vehicle instrument body is existing technology, and this application does not further limit the model of the vehicle instrument body. The cleaning bristles adhered to the outer surface of the cleaning sleeve are in contact with the display screen on the upper surface of the vehicle instrument body. As the cleaning sleeve moves and rotates, it can clean the dust and foreign objects on the display screen on the upper surface of the vehicle instrument body.

[0011] Furthermore, a control door is hinged to the inner wall of the main body of the testing box, and a handle is fixedly connected to the outer surface of the control door. An image analyzer is installed on the upper surface of the main body of the testing box. The image analyzer is existing technology, and this application does not further limit the model of the image analyzer. The image analyzer is electrically connected to a camera installed on the inner top wall of the main body of the testing box. After the camera takes a picture of the display screen on the vehicle instrument panel, it can transmit the image to the image analyzer. After the image analyzer analyzes the image, it can determine whether the vehicle instrument panel is qualified.

[0012] One end of the gear three has an extension section rotatably mounted in the corresponding rack three. The extension section has a shaft hole with a keyway on its inner wall. A threaded section is located at the end of the crossbar near the extension section, with a sliding key at its end. The threaded section is threadedly mounted in a threaded sleeve, which is fixedly connected to the corresponding rack three. The end of the crossbar opposite the extension section slides through the corresponding rack three, so that when the gear three rotates, the crossbar rotates synchronously and moves axially. A control door is hinged to the inner wall of the detection box body, and a handle is fixedly connected to the outer surface of the control door. An image analyzer is mounted on the upper surface of the detection box body.

[0013] Meanwhile, the automotive instrument testing method of the present invention uses an automotive instrument testing box for testing. The carrier plate is first pulled out a certain distance, and then placed into the automotive instrument body with its display screen facing upward. Ensure that the cleaning sleeve is located above the automotive instrument body and pushed into the testing box body. The cleaning sleeve moves relative to the display screen towards the inside of the testing box body while moving along the axial direction of the cleaning sleeve to clean the display screen. Then, an image analyzer is used to perform image analysis on the display screen.

[0014] Compared with existing technologies, this automotive instrument panel testing box has the following advantages:

[0015] First, this invention can clean the display screen of the vehicle instrument panel when it is placed inside the testing box for testing, thereby effectively preventing the camera from including dust or foreign objects in the image, or cleaning the dust and dirt on the surface of the instrument display screen in advance. When the computer recognizes the image, it will not be interfered with, thus ensuring the accuracy of the device in judging whether the vehicle instrument panel is qualified.

[0016] Second, this invention enables workers to easily fix the vehicle instrument panel body when placing it into the testing box for testing, further ensuring the accuracy of the test results. By placing the vehicle instrument panel body on the placement plate, the placement plate will move downward under the action of gravity, thereby driving the transmission rod to rotate. As the transmission rod rotates, it can drive the sliding rods to move closer together, so that the clamping plate contacts the outer surface of the vehicle instrument panel body, thereby achieving clamping and fixing of the vehicle instrument panel body.

[0017] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] like Figure 2 and Figure 3 As shown, the present invention provides a technical solution: an automotive instrument testing box, including a testing box body 1. The testing box body 1 belongs to the prior art. A camera is installed on the inner top wall of the testing box body 1. Since this is not the main innovation direction of this application, the applicant will not show this detail in the accompanying drawings.

[0026] The inner bottom wall of the test box body 1 is connected to a support plate 2 by a push-pull sliding mechanism. The support plate 2 can slide on the inner bottom wall of the test box body 1. The test box body 1 is equipped with a cleaning mechanism 3. The cleaning mechanism 3 includes two rotating shafts 301, two racks 1 304, two racks 2 305 and two racks 3 306. Both rotating shafts 301 are vertically rotatably connected to the inner bottom wall of the test box body 1. The bottom end of both rotating shafts 301 is fixedly connected to a gear 1 (not shown in the figure). The rotation of the gear 1 can drive the rotation of the rotating shaft 301.

[0027] The top ends of both rotating shafts 301 are fixedly connected to gear 303, which is... Figure 3 The cylindrical gear located above the aforementioned gear one can drive the rotation of gear two 303 as the shaft 301 rotates. Two connecting rods 307 are fixedly connected to the upper surfaces of both racks three 306. Each connecting rod 307 is slidably connected to the inner top wall of the detection box body 1. The slidable connection of the connecting rods 307 to the inner top wall of the detection box body 1 provides support for the racks three 306. Furthermore, in this embodiment, a crossbar 308 is rotatably connected between the two racks three 306. The two ends of the crossbar 308 are rotatably connected to the sides of the two racks three 306 that are close to each other. Symmetrical gears three 309 are fixedly connected to the two ends of the crossbar 308. The rotation of the gears three 309 can drive the rotation of the crossbar 308.

[0028] Specifically, a cleaning sleeve 310 is fixedly connected to the outer surface of the crossbar 308, and cleaning soft bristles are adhered to the outer surface of the cleaning sleeve 310. A placement plate 4 is provided inside the main body 1 of the detection box, and a symmetrical fixing mechanism 5 is provided inside the main body 1 of the detection box.

[0029] Both racks 304 are fixedly connected to the outer surface of the support plate 2. As the support plate 2 moves, it drives the racks 304 to move as well. Gear 1 meshes with racks 304, and the movement of racks 304 drives gear 1 to rotate. Both racks 305 are fixedly connected to the upper surface of the support plate 2. Gear 309 meshes with racks 305, and the movement of the support plate 2 drives the racks 305 to move as well. The movement of racks 305 drives gear 309 to rotate.

[0030] like Figure 2 and Figure 4 As shown, the fixing mechanism 5 includes a clamping plate 501. Symmetrical sliding rods 502 are fixedly connected to the outer surface of the clamping plate 501. Fixed cylinders 503 are slidably connected to the outer surfaces of both sliding rods 502. The sliding rods 502 can slide on the inner wall of the fixed cylinders 503, and the frictional resistance between the sliding rods 502 and the fixed cylinders 503 is relatively small. Both fixed cylinders 503 are fixedly connected to the inner wall of the bearing plate 2, and springs 504 are fixedly connected to the inner walls of both fixed cylinders 503. The sliding rods 502 are fixedly connected to the springs 504. By setting the springs 504, a reset function can be achieved. As the sliding rods 502 slide outwards, the springs 504 can be stretched.

[0031] The bottom surfaces of the two sliding rods 502 are hinged with transmission rods 505, and each transmission rod 505 is hinged to the placement plate 4. The upper surface of the placement plate 4 is provided with a vehicle instrument body 6. The vehicle instrument body 6 is prior art, and this application does not further limit the model of the vehicle instrument body 6. The cleaning soft bristles attached to the outer surface of the cleaning sleeve 310 are in contact with the display screen on the upper surface of the vehicle instrument body 6. As the cleaning sleeve 310 moves and rotates, it can clean the dust and foreign objects on the LCD display screen on the upper surface of the vehicle instrument body 6.

[0032] like Figure 1 As shown, a control door 7 is hinged to the inner wall of the detection box body 1, and a handle 8 is fixedly connected to the outer surface of the control door 7. An image analyzer 9 is installed on the upper surface of the detection box body 1. The image analyzer 9 is prior art, and this application does not further limit the model of the image analyzer 9. The image analyzer 9 is electrically connected to the camera installed on the inner top wall of the detection box body 1. After the camera takes a picture of the LCD screen on the vehicle instrument body 6, it can transmit the image to the image analyzer 9. After the image analyzer 9 analyzes the image, it can determine whether the vehicle instrument is qualified. After the vehicle instrument body 6 is placed on the placement plate 4, it must be ensured that the LCD screen on the vehicle instrument body 6 is located below the cleaning sleeve 310.

[0033] Working principle: During the use of this device, it is necessary to first pull out the support plate 2 a certain distance, for example, by... Figure 2-3In the structure shown, the position of the support plate 2 is the starting point. Pulling it outwards, the crossbar 308 and the cleaning sleeve 310 also move outwards relative to the main body 1 of the detection box. When the support plate 2 is pulled to a position suitable for placing the vehicle instrument panel 6, specifically, the vehicle instrument panel 6 should be placed as close as possible to the inside of the detection box 1 than the cleaning sleeve 310, so that it can be cleaned by the subsequently retracting cleaning sleeve 310. Regarding the cleaning of the display screen surface of the instrument panel by the cleaning sleeve 310, the optimal implementation structure is that gear two 303 is larger than gear one, while rack one 304 and rack three 306 are the same. If the length of rack two 305 on the support plate 2 is sufficient, the speed at which the crossbar 308 and the cleaning sleeve 310 move with rack three 306 will be faster than the speed at which the support plate 2 moves, generating relative motion. This effectively achieves the cleaning of the vehicle instrument panel 6 by the cleaning sleeve 310, resulting in the most comprehensive cleaning.

[0034] Specifically, for example, first open the control door 7, then slide the support plate 2 outwards until the vehicle instrument body 6 can be placed on the placement plate 4. The vehicle instrument body 6 can be clamped and fixed by the two clamping plates 501 approaching each other. Then, the operator pushes the support plate 2 into the test box body 1. As the support plate 2 moves inwards, the rack 304 moves inwards, thereby driving the gear 1 to rotate. Since the rack 306 is not connected to the support plate 2, the rotation of the gear 1 can drive the gear 2 to rotate. The rotation of the coaxially fixed gear 303 drives the rack 306 to move inward. As the rack 306 moves inward, it drives the crossbar 308 and the cleaning sleeve 310 to move inward as well. The movement of the crossbar 308 drives the gear 309 to move inward. Since the gear 309 is meshed with the rack 305, it also rotates, thus driving the cleaning sleeve 310 to rotate. This achieves linear movement of the cleaning sleeve 310 while simultaneously rotating around its own axis. The cleaning soft bristles on the outer surface of the cleaning sleeve 310 clean dust and foreign objects from the outer surface of the LCD screen on the vehicle instrument panel 6, effectively preventing the camera from including dust or foreign objects in the image and avoiding interference with the computer's image recognition. This further ensures the accuracy of the device's judgment on the vehicle's instrument panel's compliance.

[0035] As a specific implementation structure, such as Figure 5One end of the gear 309 has an extension 10 rotatably mounted in the corresponding rack 306. The extension 10 has a shaft hole with a keyway 12 on its inner wall. This keyway 12 may penetrate the entire wall of the shaft hole or not. Furthermore, the end of the crossbar 308 near the extension 10 has a threaded section 14. At the end of the threaded section 14 is a sliding key 13, which is fixed to the end of the threaded section 14 and radially positioned thereto. The threaded section 14 is threadedly mounted in a threaded sleeve 11, which is integrally fixed to the corresponding rack 306 for synchronous translation. Correspondingly, the end of the crossbar 308 opposite to the extension 10 slides through its corresponding rack 306, so that when the gear 309 rotates, the crossbar 308 rotates synchronously and moves axially, thereby wiping and cleaning the car's instrument panel display horizontally.

[0036] More specifically, based on the above automotive instrument panel testing box, during use, the support plate 2 is first pulled out a certain distance, and then placed into the automotive instrument panel body with its display screen or display panel facing upwards. The cleaning sleeve 310 is positioned above the automotive instrument panel body, and then the support plate 2 is pushed into the testing box body 1. The cleaning sleeve 310 moves relative to the display screen towards the inside of the testing box body 1, thus performing a rolling cleaning and wiping motion on the display screen in the width direction. Simultaneously, it moves along the axial direction of the cleaning sleeve 310 to perform a moving cleaning and wiping motion on the display screen in the length direction. This allows for very flexible and thorough cleaning of the display panel. Afterwards, the image analyzer 9 is used to perform image analysis on the automotive instrument panel display screen to obtain the appearance condition of the instrument panel, or to identify and determine whether the actual arrow indication position of the instrument panel matches the speed value generated by the corresponding input torque, thereby assisting in more accurate testing of the automotive instrument panel.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
