Description

Technical Field

[0001] This invention relates to the field of product testing technology, and in particular to a testing device for automotive US-type communication products. Background Technology

[0002] With the increasing popularity of new energy vehicles and the enhancement of various auxiliary and entertainment functions in automobiles, more and more cars are choosing to add USB 3.1 high-speed communication ports. A test program was developed to effectively test the communication rate and loopback performance of the USB 3.1 high-speed communication port. Through software design and programming, combined with hardware design and manufacturing, the program ultimately achieves automatic product function testing. By reading communication information, it effectively prevents the outflow of untested products, ensuring the uniqueness of product testing records and the traceability of product status. Functional testing is required after electronic products are manufactured. Product testing requires the fixed installation and rapid removal of the product and testing equipment. After installation, it connects to the testing tool PASSMARSK, and the product is removed and replaced. High stability is required during installation to ensure the accuracy of test results, and rapid installation and removal improve testing efficiency. Simultaneously, the surface of the electronic product must be protected during installation and removal to prevent affecting test accuracy.

[0003] Chinese Patent Publication No.: CN 216526071 U, Publication Date: May 13, 2022. This utility model provides a product testing and fixing mechanism, characterized by: a base plate with two opposing bases on the base plate, a channel for placing the product between the two bases, and rollers on the bases that can move towards or away from the channel. A mounting ear is provided on the side of the base near the channel, and a sliding groove is provided within the mounting ear. The rollers are installed in the sliding groove and can move towards or away from the channel along the sliding groove. The shortcomings of this technical solution are that the placement operation is not smooth, the simple fixing structure reduces stability, thus affecting testing accuracy, and the removal of the product is cumbersome, making it impossible to quickly remove and replace the tested product, affecting overall testing efficiency.

[0004] In summary, the product's unstable mounting affects testing accuracy, and the difficulty in quickly removing and replacing it impacts testing efficiency. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of existing technologies, such as unstable product fixation, which affects test accuracy, and difficulty in quick removal and replacement, which affects test efficiency. It provides a test device for automotive US-type communication products that is stable to place, easy to remove, and improves test accuracy and efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A testing device for automotive US-type communication products includes an operating table and a fixing component. The operating table is provided with a detection slot. The fixing component includes a locking block and a top block, which are placed in the detection slot. The locking block is provided with a locking groove, and a pressure plate is slidably connected to the locking block. There are several locking blocks, and a connecting rod is connected between adjacent locking blocks. The top block is slidably connected to the detection slot, and an inclined surface is provided on the top block.

[0008] The testing slot is used to place the product to be tested. A fixing component allows the product placed in the testing slot to move. Several locking blocks are embedded within the testing slot, with adjacent blocks connected by a connecting rod. Each locking block has a slot for the product to be tested to be inserted, allowing for quick and easy positioning. A pressure plate connected to the locking blocks can slide back and forth, securing the product after it is placed in the slot and preventing displacement during testing, thus achieving a stable installation. A top block slides linearly within the testing slot on both sides of the connecting rod. The top block has an inclined surface, with the lower end of the inclined surface facing the testing slot. There is a height difference between the upper end of the connecting rod and the bottom of the slot, creating a distance between the product and the connecting rod after placement, facilitating heat dissipation. Simultaneously, by sliding the top block between the connecting rod and the product, the inclined surface gradually lifts the product, allowing it to quickly detach from the locking block and exit the slot for easy removal. This achieves convenient placement, stability, and improved testing accuracy, while also facilitating easy removal and increasing testing efficiency.

[0009] Preferably, a buffer block is provided inside the slot, and the buffer block is elastically connected to the card block. The connection between the included angle surfaces of the buffer block is arc-shaped. The structural shape of the buffer block matches the structural shape of the product to be tested. At the same time, the elastic connection between the buffer block and the card block allows the buffer block to move bufferingly when the product to be tested is placed in, preventing the product from being scratched and protecting the product. In addition, the transition surface between the two included angle surfaces of the buffer block that first contact the product is arc-shaped, so that the surface formed by the included angle surfaces has a guiding and buffering function, allowing the product to be placed quickly and smoothly, facilitating placement while further protecting the product.

[0010] Preferably, the locking block is provided with a groove, and a slider is connected to the buffer block, with the slider slidably connected to the groove. The locking block has a strip groove in the direction of being pushed by the product, and the bottom surface of the buffer block is connected to the slider. The insertion of the slider and the groove allows the locking block to produce stable linear movement when pushed, so that the locking block is subjected to balanced force and moves stably, thereby improving the smoothness of product installation.

[0011] Preferably, the card block has a slot, and the pressure plate is inserted into the slot. An insert plate is connected inside the slot, and a slide rail is connected to the pressure plate. The insert plate and the slide rail are slidably connected, and the corner of the pressure plate has an arc-shaped transition. The pressure plate is inserted into the slot and can slide, allowing the pressure plate to stabilize the product's placement while facilitating its movement. The insert plate inside the slot inserts into the slide rail of the pressure plate, ensuring the pressure plate slides smoothly, preventing collisions between the pressure plate and the product, and securing the product while improving installation stability.

[0012] Preferably, a support rod is connected to the operating platform, a rotating rod one is connected to the pressure plate, and a rotating rod two is connected to the top block. A connecting rod is rotatably connected to the support rod, with one end of the connecting rod rotatably connected to rotating rod one and the other end rotatably connected to rotating rod two. One end of the support rod is connected to the operating platform, and the other end is rotatably connected to the connecting rod, allowing the connecting rod to rotate around the support rod as a fulcrum. Rotating rod one is connected to the surface of the pressure plate, and rotating rod two is connected to the surface of the top block. Both ends of the connecting rod are connected to rotating rod one and rotating rod two respectively, so that the connecting rod can press the pressure plate and the top block in opposite directions when rotating. This allows for quick installation and removal of products by rotating the connecting rod, thus improving loading and unloading efficiency.

[0013] Preferably, two limit blocks are connected to the support rod, with the connecting rod positioned between them. Limit rods are provided above and below the connecting rod, which restrict the vertical displacement of the connecting rod on the support rod, thereby limiting the displacement of the connecting rod on rotating rod one and rotating rod two, preventing the connecting rod from coming off or causing wear such as friction, while also improving the stability of the structural connection and the smoothness of operation.

[0014] Preferably, the operating platform is provided with a stabilizing groove, and a stabilizing block is connected to the top block, with the stabilizing block slidably connected to the stabilizing groove. The stabilizing groove is a strip-shaped recess on the operating platform, and the stabilizing block is connected to the side of the top block. The stabilizing block is placed in the stabilizing groove, and when the top block moves, the stabilizing block moves along with it in the stabilizing groove to prevent the top block from rotating, so that the top block makes stable linear movement, thereby improving structural stability and operational smoothness.

[0015] Preferably, the operating platform is housed within a casing. The casing contains the PASSMARK testing tool and a lifting mechanism. The lifting mechanism includes a base plate and a rotating mechanism. A rotating column is threaded onto the operating platform. One end of the rotating mechanism is mounted on the base plate, and the other end is rotatably connected to the rotating column. The PASSMARK, lifting mechanism, and operating platform are housed within the casing, which is made of a light-shielding material to prevent light interference with the testing. The PASSMARK, including signal cable aviation sockets, air source sockets, and continuity probe structures, is used to connect to the product under test for testing. The casing protects the PASSMARK from moisture. The lifting mechanism, consisting of a base plate and a rotating mechanism, has threaded holes on the operating platform. The rotating column is threaded through these holes and connected to the rotating mechanism on the base plate. This rotation allows the operating platform to be raised and lowered, facilitating the handling and placement of the product and improving the ease of loading and unloading during testing.

[0016] Preferably, the enclosure is equipped with a door, which is rotatably connected to the enclosure. The door has an observation window positioned opposite the testing slot. The door opens or closes the enclosure by rotating it, facilitating maintenance of the PASSMARSK testing tool and providing dust protection. The observation window's alignment with the testing slot allows for easy product retrieval, thus improving testing efficiency.

[0017] Preferably, the observation window is equipped with a sliding plate, which is slidably connected to the observation window, and a pusher is connected to the sliding plate. The sliding plate slidably connects to the observation window, allowing for easy switching between the open and closed states of the observation window via the pusher connected to the sliding plate, thus improving the flexibility of the observation window's use.

[0018] The beneficial effects of this invention are: the product is easy to place and stable, improving testing accuracy; it can also be easily removed to improve testing efficiency; placement and removal are quick and smooth; the structure is highly stable, protecting the product surface and reducing wear; the product dissipates heat quickly during testing; and product replacement is flexible and convenient.

[0032] Example 1:

[0033] like Figure 1-3 As shown, a testing device for automotive US-type communication products includes an operating table 1 and a fixing assembly 29. The operating table 1 has a test slot 2. A housing 19 surrounds the operating table 1, and the operating table 1 is placed inside the housing 19. The housing 19 houses a testing tool, PASSMARSK, and a lifting mechanism. The lifting mechanism includes a base plate 20 and a rotating mechanism. A rotating column 21 is threaded onto the operating table 1. One end of the rotating mechanism is mounted on the base plate 20, and the other end is rotatably connected to the rotating column 21. The housing 19 has a door 22, which is rotatably connected to the housing 19. An observation window 23 is provided on the door 22, and the observation window 23 is positioned opposite the test slot 2. A sliding plate 24 is provided on the observation window 23, and the sliding plate 24 is slidably connected to the observation window 23. A pusher block 25 is connected to the sliding plate 24.

[0034] like Figure 4-8As shown, the fixing component 29 includes a locking block 3 and a top block 4. The locking block 3 and the top block 4 are placed in the detection groove 2. The locking block 3 has a locking groove 26, and a pressure plate 5 is slidably connected to the locking block 3. There are several locking blocks 3, and a connecting rod 6 connects adjacent locking blocks 3. The top block 4 is slidably connected to the detection groove 2, and the top block 4 has an inclined surface. A buffer block 7 is provided in the locking groove 26, and the buffer block 7 is elastically connected to the locking block 3. The connection of the included angle surface of the buffer block 7 is arc-shaped. The locking block 3 has a sliding groove 8, and a slider 27 is connected to the buffer block 7. The slider 27 is slidably connected to the sliding groove 8. The locking block 3 has a slot 9, and the pressure plate 5 is inserted into the slot 9. An insert plate 10 is connected in the slot 9, and a slide rail 11 is connected to the pressure plate 5. The insert plate 10 is slidably connected to the slide rail 11, and the connection of the included angle surface of the pressure plate 5 is arc-shaped. A support rod 12 is connected to the operating table 1, a rotating rod 13 is connected to the pressure plate 5, and a rotating rod 14 is connected to the top block 4. A connecting rod 15 is rotatably connected to the support rod 12, with one end of the connecting rod 15 rotatably connected to the rotating rod 13 and the other end of the connecting rod 15 rotatably connected to the rotating rod 14. Two limit blocks 16 are connected to the support rod 12, and the connecting rod 15 is positioned between the limit blocks 16. A stabilizing groove 17 is provided on the operating table 1, and a stabilizing block 18 is connected to the top block 4, with the stabilizing block 18 slidably connected to the stabilizing groove.

[0035] like Figure 1-8 As shown: the testing slot 2 is used to place the automotive US-type communication product 28 to be tested. The fixing component 29 allows the product placed in the testing slot 2 to move. Several locking blocks 3 are embedded in the testing slot 2. Adjacent locking blocks 3 are connected as a whole by connecting rods 6. Each locking block 3 is provided with a slot 26 for the product 28 to be tested to be inserted into the slot 26, allowing the product 28 to be positioned and placed quickly. The pressure plate 5 is connected to the locking block 3 and can slide back and forth. After the product 28 is placed in the testing slot, the pressure plate 5 can fix the product 28, preventing it from shifting during testing and achieving a stable installation effect. The top block 4 is slidably connected to the operating table 1 and can move linearly. The surface of the top block 4 has an inclined surface, and the lower end of the inclined surface faces the detection slot 2. There is a height difference between the upper end of the connecting rod 6 and the bottom of the slot of the operating table 1, so that there is a distance between the product to be tested 28 and the connecting rod 6 after it is placed in, which facilitates the heat dissipation of the product 28. At the same time, by sliding the top block 4 under the connecting rod, the product 28 is gradually lifted up under the action of the inclined surface, so that the product 28 can be quickly separated from the card block 3 and removed from the slot 26, so as to facilitate the quick removal of the product 28. This achieves the effect of convenient placement, stability and improved testing accuracy, while also facilitating easy removal and improving testing efficiency.

[0036] The operating table 1 is placed inside the housing 19, and the fixing component 26 is installed on the detection slot 2 of the operating table 1. After the product 28 is installed with the fixing component 26, it is connected to the testing tool PASSMARK (not shown in the figure) for testing. The testing tool PASSMARK is externally connected to a start button, a computer host, a barcode scanner, and a printer.

[0037] The fixing component 26 can adjust the number of locking blocks 3 and the position of the top block 4 according to the shape of the product, making the structure of the fixing component 26 universal. In this embodiment, the product 28, a vehicle-mounted US-type communication device, is rectangular in shape. The fixing component 26 has four locking blocks 3, which are connected by connecting rods 6 to form a rectangular structure. The locking blocks 3 are placed at the four corners. The slots 26 on the locking blocks 3 are L-shaped slots with two vertical surfaces connected. There are two buffer blocks 7 in the slots 26. One of the buffer blocks 7 slides on the side of the other side to form an L-shaped slot to facilitate placement of the product 28 at the corners. One side of the buffer block 7 is in contact with the product, and the contact surface is made of soft rubber material, which protects the surface of the product 28 while increasing the friction between the product and the buffer block 7, making the product 28 more stable. A spring is connected to the side of the buffer block 7 opposite to the groove surface of the slot 26. The other end of the spring is connected to the buffer block 7, allowing the buffer block 7 to slide and return to its original position. This generates a certain amount of pressure on the product 28, making it difficult for the product 28 to move. The slider 27 is connected to the lower end face of the buffer block 7, and the slide groove 8 is set at the bottom of the slot 26, ensuring the stability of the buffer block's linear movement during movement.

[0038] The top block 4 is positioned between two adjacent locking blocks 3. Two top blocks 4 are arranged opposite each other, allowing the top blocks 4 to evenly lift the product 28 while simplifying the structure and making operation easier. The upper end of the top block 4 is connected to the rotating rod 14, and the lower end of the top block 4 is in contact with the surface of the operating table 1, allowing the top block 4 to slide on the operating table 1 under force, thereby lifting the product 28. Stabilizing blocks 18 are connected to both sides of the top block 4, and these stabilizing blocks 18 are inserted into stabilizing grooves 17, ensuring that the sliding of the top block 4 is linear, facilitating the even application of force to lift the product 28. A soft pad is attached to the inclined surface of the top block 4 that contacts the product 28 to protect the surface of the product 28.

[0039] Two connecting rods 15 are connected to the rotating rod 14. Both connecting rods 15 are provided with relief grooves 30 to leave room for the rotation of the connecting rods 15 on the rotating rod 14, while ensuring that the other ends of the two connecting rods 15 are flush, thus facilitating the application of force and ensuring stable movement, and the overall uniformity of the structural layout.

[0040] The relative positions of the pressure plate 5 and the top block 4 are arranged so that their contact with the product 28 is not simultaneous, that is, the pressure plate 5 and the top block 4 contact the product 28 alternately, to prevent the two structures from exerting contradictory forces on each other and affecting the fixing and unloading of the product.

[0041] The support rods 12 are symmetrically arranged on both sides of the top block 4, so that the connecting rods 15 on both sides of the top block 4 are connected in a balanced and stable manner. Thus, by moving the top block 4, the movement and reset of the two pressure plates 5 can be operated simultaneously, thereby improving the operating efficiency.

[0042] The lifting height of the rotating column 21 is matched with the space occupied by the box 19 and the comfortable placement height for operation, so that the box 19 is not too large and occupies too much space, while facilitating the placement and retrieval of the product 28.

[0043] The slide plate 24 has four pieces placed on the observation window 23. The observation window 23 can be opened and closed by sliding. The product 28 can be temporarily replaced through the observation window 23, so that the operating table 1 does not need to lift and lower to quickly replace the product 23, thus enhancing the flexibility of the test equipment.

[0044] During testing, first, a QR code label is affixed to the automotive US-type communication product 28. Then, the product 28 is scanned using the QR code and placed into the fixing component 29 on the housing 19. The product 28 is then placed in the testing slot 2 for fixation. The housing door 22 is opened, and the rotating mechanism (not shown, but a rotary motor is used) is activated to rotate the rotating column 21, raising the operating platform 1 and positioning the fixing component 29 in a convenient installation position. The product 28 is then placed into the slots 26 along the buffer blocks 7, securing it in place. The top blocks 3 on both sides are moved in the opposite direction to the testing slot 2, causing the pressure plate 5 to move towards the testing slot 2. The pressure plate 5 gradually moves above and into contact with the product 28, preventing movement. Once the product 28 is secured, it is connected to the testing tool PASSMARK. The rotating mechanism rotates in the opposite direction, lowering the operating platform 1. The housing door 22 is closed, and the PASSMARK start button is pressed to begin testing the product 28. The test includes the product's output voltage, loopback test, USB 3.0 / 2.0 speeds on the front and back sides respectively, and whether any error messages are generated during the test. The test results are then printed out via a computer.

[0045] After testing, close the testing tool PASSMARSK and remove the automotive US-type communication product 28 from the testing slot 2. Open the door 22, start the rotating mechanism to rotate the rotating column 21 and raise the operating platform 1, raising the fixing component 29 to a suitable position for easy installation. Disconnect the product 28 from the testing tool PASSMARSK, and then move the top blocks 3 on both sides toward the testing slot 2, so that the four pressure plates 5 simultaneously leave the product 28. The top blocks 3 continue to move and insert between the connecting rod 6 and the product 28, so that the product 28 is gradually lifted by the inclined surface of the top blocks 3, and then the product 28 can be easily detached from the fixing component 29. The product 28 can then be taken out.

[0046] Quickly replace the US-type communication product 28 for the test vehicle: Close the test tool PASSMARK, open the slide plate 24 to open the observation window 23, disconnect the product 28 from the test tool PASSMARK, then move the top blocks 3 on both sides toward the test slot 2, so that the four pressure plates 5 simultaneously leave the product 28. The top blocks 3 continue to move and insert between the connecting rod 6 and the product 28, so that the product 28 is gradually lifted by the inclined surface of the top blocks 3, and then the product 28 can easily detach from the fixing component 29. Take out the product 28, and put the replacement product 28 into the slot 26 along each buffer block 7, so that each slot 3 fixes the replacement product 28. Move the top blocks 3 on both sides in the opposite direction to the test slot 2, so that the pressure plates 5 move toward the test slot 2, and then the pressure plates 5 are gradually placed above the replacement product 28 and in contact with the replacement product 28 to prevent the replacement product 28 from moving. The replacement product 28 is now fixed. Connect the replacement product 28 to the test tool PASSMARK, slide the slide plate 24 to close the observation window 23, and you can start testing the replacement product 28.
