They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0055] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0056] like Figures 1 to 4 As shown, the vehicle cable continuity testing device of this utility model compares and judges all endpoints of the vehicle cable, and finally determines the continuity and wiring status of the entire cable, and displays the cable detection information at the end of the test in the display window.

[0057] Based on the displayed information, staff identify four error types: open circuit, mismatch, short circuit, and airtightness. The graphical interface displays information including: error type, location of the faulty wire on the cable, shape of the connector containing the faulty wire, wire color, and wire number. The interface also provides corrective suggestions. The testing operator locates the faulty wire according to the interface prompts and corrects the cable accordingly. After all tests are passed, the cable is sent to the printer, which prints a product qualification label. Continuity testing of the vehicle's cables ensures the product's compliance.

[0058] like Figures 1 to 4 As shown, the vehicle cable continuity testing device of this utility model includes a mounting body 1 and a testing module 2. The mounting body 1 is used to support the testing module 2. The testing module 2 has a testing interface and is used to connect the cable to be tested. Through the testing module 2, the cable to be tested is tested to determine the continuity and wiring condition of the cable.

[0059] Due to differences in vehicle models, the height of the vehicle cables varies. To ensure a smooth connection between the vehicle cables and the testing equipment, the testing equipment needs to be moved to a location near the vehicle cables. When testing is demanding, frequent movement of the testing equipment is necessary, increasing labor intensity and reducing testing efficiency.

[0060] To address the aforementioned issues, the vehicle cable continuity testing device of this invention further includes a height adjustment unit 3. The height adjustment unit 3 is mounted on the mounting body 1 and is used to raise or lower the testing module 2 to adjust its height. By incorporating the height adjustment unit 3, the height of the testing body can be adjusted as needed, facilitating the connection of the vehicle cables under test, improving the convenience of continuity testing, and increasing testing efficiency.

[0061] In this embodiment, the height adjustment unit 3 can be manually adjustable or automatically adjustable (electric). Preferably, the height adjustment unit 3 is automatically adjustable. The automatically adjustable height adjustment unit 3 can quickly and accurately adjust the height of the test module 2, reduce labor intensity, improve adjustment efficiency, and thus improve test efficiency.

[0062] In this embodiment, the height adjustment unit 3 is a nested structure. Specifically, adjacent nested structures are connected by threads or sliding connections to change the height of the test module 2.

[0063] In this embodiment, the height adjustment unit 3 includes a fixed unit 31 and a movable unit 32, with the test module 2 located on top of the movable unit 32. When the fixed unit 31 and the movable unit 32 are nested, the fixed unit 31 is fixedly installed on the mounting body 1 to provide support. The movable unit 32 is connected to the fixed unit 31 via a threaded or sliding connection.

[0064] Specifically, the cross-sectional area of ​​the fixed unit 31 is larger than the cross-sectional area of ​​the movable unit 32. The fixed unit 31 is hollow, and the movable unit 32 can be inserted into the fixed unit 31.

[0065] When the fixed unit 31 and the movable unit 32 are threadedly connected, the movable unit 32 can be screwed out of or into the fixed unit 31 by rotating the fixed unit 31 and the movable unit 32 relative to each other. Since the length of the fixed unit 31 is always fixed, the height of the test module 2 can be adjusted by changing the length of the movable unit 32 protruding from the fixed unit 31.

[0066] When the fixed unit 31 and the movable unit 32 are slidably connected, the movable unit 32 slides out of or into the fixed unit 31 by sliding relative to the fixed unit 31. Since the length of the fixed unit 31 is always fixed, the height of the test module 2 can be adjusted by changing the length of the movable unit 32 that protrudes from the fixed unit 31.

[0067] Specifically, the moving unit 32 can be moved by a linear motor or by a nut and screw mechanism, etc. Linear motors, nut and screw mechanisms, etc., are structures well-known to those skilled in the art, and will not be described in detail in this embodiment.

[0068] In this embodiment, the cross-sections of the fixed unit 31 and the movable unit 32 can be rectangular, circular, or other shapes. When the fixed unit 31 and the movable unit 32 are threaded together, it is necessary to ensure that both the fixed unit 31 and the movable unit 32 are circular to ensure that they can rotate relative to each other.

[0069] In this embodiment, the fixed unit 31 and the moving unit 32 are coaxially arranged to ensure stability during movement and the overall structural stability. Of course, a guiding mechanism, such as a guide rod or guide groove, can also be added to further improve stability.

[0070] In this embodiment, multiple moving units 32 can be provided, and the fixed unit 31 and multiple moving units 32 form a multi-level nested structure to increase the adjustment stroke. Through the hierarchical nested structure, while increasing the adjustment stroke, each level of moving unit 32 can be hidden in the moving unit 32 of the previous level or the fixed unit 31 when not in use, saving storage space.

[0071] In this embodiment, the height adjustment unit 3 can also be a telescopic structure, which can change the height of the test module 2 by extending or shortening. Specifically, the height adjustment unit 3 can be a cylinder, an electric cylinder, an electric push rod, etc., or it can be a telescopic frame, a lift, etc.

[0072] In this embodiment, the vehicle cable continuity testing device of this utility model also includes a test mounting platform 4, which is connected to the top of the moving unit 32 to facilitate the installation and fixation of the test module 2. Specifically, a limiting groove 41 is formed on the top of the test mounting platform 4, and the bottom of the test module 2 is embedded in the limiting groove 41. The test module 2 is fixed by snapping together with the limiting groove 41. Snapping can also be achieved through other mechanisms such as clips, or a detachable connection can be achieved through screws, bolts, etc.

[0073] In this embodiment, the test installation platform 4 is tilted from back to front, and the rear end of the test installation platform 4 is higher than the front end. When the staff operates the test installation platform 4, the display interface of the test module 2 on the test installation platform 4 is facing the staff.

[0074] In this embodiment, the test installation platform 4 includes a first storage unit 42 and a panel 43. The first storage unit 42 is connected to the top of the moving unit 32. The first storage unit 42 has a cavity and is used to install a relay. The relay is used to enhance and expand the signal transmission and reception range, solving the communication and interaction problem of test data when there is signal shielding or network interruption in the factory.

[0075] In this embodiment, the panel 43 is detachably connected to the first storage unit 42, and a limiting groove 41 is provided on the upper surface of the panel 43. The detachable connection between the panel 43 and the first storage unit 42 can be a snap-fit ​​connection, a screw connection, etc.

[0076] In this embodiment, the test installation platform 4 is provided with multiple hooks 5, which are used to hang test adapters for quick selection. In this embodiment, the cable reel of the test adapter can also be hung here for quick storage and retrieval of the cable.

[0077] In this embodiment, each hook part 5 is located on the outer wall of the test installation platform 4, that is, on the outer wall of the first storage unit 42 in the left and right directions. The hook parts 5 are arranged linearly, and multiple test adapters can be hung at the same time.

[0078] In this embodiment, the vehicle cable continuity testing device of this utility model further includes a second storage unit 6, which is disposed on the outer wall of the fixing unit 31. The second storage unit 6 has a second storage cavity 61 with a top opening. The second storage unit 6 can be used to store cables or other tools. At the same time, the second storage unit 6 makes full use of the space below the testing module 2 by utilizing the outer wall of the fixing unit 31.

[0079] In this embodiment, the mounting body 1 includes a base 11 and a handle 12. The base 11 is used to mount the height adjustment unit 3, and the handle 12 is connected to the base 11. The handle 12 is located on one side of the height adjustment unit 3.

[0080] In this embodiment, the vehicle cable continuity testing device of this utility model further includes a moving mechanism 7, which is installed at the bottom of the mounting body 1 and is used to move the mounting body 1. By setting the moving mechanism 7, flexibility is improved, and frequent manual handling of continuity testing equipment and testing adapters can be effectively avoided, achieving the effect of rapid testing and rapid completion.

[0081] In this embodiment, the handle 12 has a frame structure, which reduces the overall weight. The handle 12 extends upward from the base 11 to facilitate pushing by the operator.

[0082] In this embodiment, the moving mechanism 7 can be a swivel caster, which improves flexibility and facilitates changing direction during movement. Depending on the movement requirements, it can be designed with wheels equipped with locking units; that is, the two front wheels are swivel casters for easy direction changes, while the two rear wheels are equipped with locking units to secure the testing device upon arrival at its destination, preventing movement during testing.

[0083] The locking unit can be directly installed on the rear wheel, locking it by pressing down. Alternatively, it can be installed on the handheld part 12, which has a pressure bar. Pressing down the pressure bar releases the wheel lock, allowing the testing device to move normally. When the pressure bar is not pressed down, the wheel locks, and the testing device cannot move normally.

[0084] In this embodiment, the base 11 is provided with a barrier 13, and the barrier 13 has a first storage cavity 14 with a top opening. Tools or cables can also be stored in the first storage cavity 14, further enhancing the storage capacity of the testing device in this embodiment. In this embodiment, the height adjustment unit 3 is partially disposed within the first storage cavity 14.

[0085] The vehicle cable continuity testing device of this invention can be designed as a vehicle body structure and can be widely used in scenarios such as rail vehicle main engine factories and vehicle depots where it is necessary to cross and frequently shuttle between construction platforms.

[0086] The working principle of this vehicle cable continuity testing device is as follows: The operator pushes the testing device to the nearest position to the cable to be tested, stops the vehicle, locks the wheels, and then prepares for the test. The height adjustment unit 3 is used to adjust the main body of the device to a suitable height. The electrical connection with both ends of the cable to be tested is established using the test adapter to create a complete test circuit. The test program and corresponding test tasks are started, with automatic continuity testing performed first. After the cable continuity test is successful, the automatic insulation test is then performed. After the test tasks are completed, the test results are uploaded to the construction system for archiving. Finally, the construction site is cleaned up, and the original cable electrical connection is restored.
