Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, specifically to an automotive testing instrument with a self-locking interface structure for vehicle testing. Background Technology

[0002] Automotive diagnostic tools are specialized devices that communicate with the vehicle's electronic control system to read and analyze various data information to determine whether a vehicle has faults and to assess its performance status. Automotive diagnostic tools are mainly connected to the vehicle's diagnostic interface (such as the common OBD-II interface) and use standard communication protocols to interact with the vehicle's electronic control unit (ECU). They can send request commands to the ECU to obtain information such as fault codes, sensor data, and actuator status stored in the ECU, and analyze and process this information, ultimately presenting it to the user in an intuitive way.

[0003] Existing automotive diagnostic tools plug the probes into the diagnostic interface for testing. However, after the probes are unplugged, the testing end lacks protection. During daily storage, dust and other contaminants can accumulate on the metal contacts of the testing end, leading to poor contact and affecting the accuracy and stability of data transmission during subsequent tests. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle testing instrument with a self-locking interface structure for vehicle testing, in order to solve the problem mentioned in the background art that in existing vehicle testing instruments, dust and other contaminants adhere to the metal contacts of the testing end during daily storage, resulting in poor contact and affecting the accuracy and stability of data transmission during subsequent testing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle testing instrument with a self-locking interface structure for vehicle inspection, comprising a vehicle testing instrument body, a connecting wire fixedly connected to the surface of the vehicle testing instrument body, a testing probe fixedly connected to the surface of the connecting wire, a protective mechanism provided on the surface of the testing probe, the protective mechanism including a guide frame, the guide frame fixedly connected to the surface of the testing probe, a slider slidably connected to the surface of the guide frame, a toggle plate fixedly connected to the surface of the slider, a rubber band fixedly connected to the surface of the toggle plate, a protective cover fixedly connected to the top of the rubber band, insertion blocks fixedly connected to both sides of the protective cover, rubber protrusions fixedly connected to the surface of the insertion blocks, and limit blocks fixedly connected to the top of both sides of the testing probe.

[0006] Preferably, the surface of the detection probe is provided with a self-locking structure, the self-locking structure including a support base, the support base being fixedly connected to the surface of the detection probe, a rotating rod being rotatably connected to the surface of the support base, a pressing block being fixedly connected to one end of the rotating rod, a linkage plate being fixedly connected to the other end of the rotating rod, a spring being fixedly connected to the surface of the rotating rod, and the end of the spring away from the rotating rod being fixedly connected to the surface of the detection probe.

[0007] Preferably, the slider is in the shape of a cross, and the rubber strip slides on the surface of the guide frame through the slider, and the rubber strip drives the protective cover to slide synchronously.

[0008] Preferably, the protective cover is slidably engaged with the top of the detection probe by a rubber band, the rubber band being made of rubber and changing the position of the protective cover on the detection probe by deformation.

[0009] Preferably, the plug-in block is T-shaped, and a limiting hole is formed on the surface of the limiting block. The plug-in block is inserted into the limiting hole of the limiting block, and the rubber protrusion is pressed against one side of the limiting hole of the limiting block.

[0010] Preferably, the spring force acts on the compression block through the rotating rod, and the compression block rotates on the surface of the detection probe through the rotating rod.

[0011] Preferably, the rotating rod is provided in four sets, and the four sets of rotating rods are connected by two sets of linkage plates. The top of the detection probe is provided with a rectangular hole, and the rotating rod rotates to make the extrusion block pass through the rectangular hole of the detection probe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this automotive testing instrument, the operator pushes the actuating plate, causing the slider to slide on the guide frame. The slider's movement moves the rubber belt, which in turn moves the protective cover towards the testing end of the probe. When the protective cover reaches the testing end of the probe, the insert blocks on both sides of the protective cover insert into the limiting holes of the top limiting blocks on both sides of the probe, and the rubber protrusions are pressed against the limiting holes of the limiting blocks. The elasticity and friction of the rubber protrusions lock the protective cover and the probe in place, effectively preventing dust and other contaminants from adhering to the metal contacts of the probe's testing end, ensuring the accuracy and stability of data transmission during subsequent testing.

[0014] 2. In this automotive testing instrument, before the operator inserts the testing probe, they press the linkage plate. The connected rotating rod rotates around the support fixed to the surface of the testing probe, overcoming the spring force to move the pressing block away from the rectangular hole of the testing probe, facilitating the insertion of the probe into the diagnostic interface. After the testing probe is fully inserted, the linkage plate is released, the spring returns to its original deformation, and the spring force, through the rotating rod, causes the pressing block to penetrate the rectangular hole and press against the diagnostic interface, achieving self-locking of the testing probe on the diagnostic interface. This prevents the testing probe from becoming loose at the diagnostic interface and improves the stability of the testing probe during the testing process. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 One embodiment provided by this utility model:

[0023] A vehicle testing instrument with a self-locking interface structure includes a vehicle testing instrument body 1. A connecting cable 11 is fixedly connected to the surface of the vehicle testing instrument body 1. A testing probe 12 is fixedly connected to the surface of the connecting cable 11. The testing probe 12 is plugged into a diagnostic interface, enabling the vehicle testing instrument body 1 to interact with the vehicle's electronic control unit. A protective mechanism is provided on the surface of the testing probe 12. The protective mechanism includes a guide frame 2, which is fixedly connected to the surface of the testing probe 12. A slider 21 is slidably connected to the surface of the guide frame 2. A toggle plate 22 is fixedly connected to the surface of the probe 12. A rubber band 23 is fixedly connected to the surface of the toggle plate 22. A protective cover 24 is fixedly connected to the top of the rubber band 23. Insertion blocks 25 are fixedly connected to both sides of the protective cover 24. Rubber protrusions 26 are fixedly connected to the surface of the insertion blocks 25. Limiting blocks 27 are fixedly connected to the top of both sides of the detection probe 12. This protective mechanism protects the detection end of the detection probe 12 through the protective cover 24, preventing dust and other contaminants from adhering to the metal contacts of the detection end of the detection probe 12, thereby avoiding poor contact and ensuring the accuracy and stability of data transmission during subsequent detection.

[0024] Furthermore, a self-locking structure is provided on the surface of the detection probe 12. The self-locking structure includes a support base 3, which is fixedly connected to the surface of the detection probe 12. A rotating rod 31 is rotatably connected to the surface of the support base 3. A pressing block 32 is fixedly connected to one end of the rotating rod 31, and a linkage plate 34 is fixedly connected to the other end of the rotating rod 31. A spring 33 is fixedly connected to the surface of the rotating rod 31, and the end of the spring 33 away from the rotating rod 31 is fixedly connected to the surface of the detection probe 12. During the connection between the detection probe 12 and the diagnostic interface, the self-locking mechanism locks the connection between the detection probe 12 and the diagnostic interface, preventing the detection probe 12 from becoming loose at the diagnostic interface and improving the stability of the detection probe 12 during the detection process.

[0025] Furthermore, the slider 21 is shaped like a cross, which can effectively prevent the slider 21 from shaking or deviating, ensuring the accuracy of its sliding trajectory. The rubber band 23 slides on the surface of the guide frame 2 through the slider 21, and the rubber band 23 drives the protective cover 24 to slide synchronously, so that the protective cover 24 can accurately reach the protective position of the detection end of the detection probe 12 or move away, providing a reliable movement method for the protection and use of the detection probe 12.

[0026] Furthermore, the protective cover 24 is slidably engaged with the top of the detection probe 12 by the rubber band 23, thereby protecting the output end of the detection probe 12. The rubber band 23 is made of rubber and can change the position of the protective cover 24 on the detection probe 12 by deformation, so that the protective cover 24 can be moved from one side of the detection probe 12 to the other side, thus avoiding the protective cover 24 from obstructing the connection between the diagnostic interface and the detection probe 12.

[0027] Furthermore, the plug-in block 25 is T-shaped, and a limiting hole is provided on the surface of the limiting block 27. The plug-in block 25 is inserted into the limiting hole of the limiting block 27, and the rubber protrusion 26 is pressed against one side of the limiting hole of the limiting block 27, thereby locking the position between the limiting block 27 and the plug-in block 25, thereby locking the position between the detection probe 12 and the protective cover 24, and enabling the installation of the protective cover 24 at the output end of the detection probe 12.

[0028] Furthermore, the elastic force of the spring 33 acts on the extrusion block 32 through the rotating rod 31. The extrusion block 32 rotates on the surface of the detection probe 12 through the rotating rod 31. The rotating rod 31 forms a lever on one side of the detection probe 12 through the support seat 3, causing the extrusion block 32 to rotate in the direction of the detection probe 12.

[0029] Furthermore, four sets of rotating rods 31 are provided, and the four sets of rotating rods 31 are connected by two sets of linkage plates 34. By pressing the two sets of linkage plates 34, the squeezing block 32 on the detection probe 12 can be released. A rectangular hole is opened at the top of the detection probe 12. The rotating rod 31 rotates so that the squeezing block 32 passes through the rectangular hole of the detection probe 12, and under the elastic force of the spring 33, the squeezing block 32 is squeezed on the diagnostic interface, thereby locking the detection probe 12 on the diagnostic interface.

[0030] Working principle: The operator connects the detection probe 12 to the main body 1 of the vehicle diagnostic instrument via the connecting cable 11 and plugs the detection probe 12 into the vehicle's diagnostic interface. This enables data interaction between the main body 1 of the vehicle diagnostic instrument and the vehicle's electronic control unit to carry out testing. When protection of the detection probe 12 is required, the operator pushes the toggle plate 22, causing the slider 21 to slide on the guide frame 2. The slider 21 moves the rubber belt 23, which in turn moves the protective cover 24 toward the detection end of the detection probe 12. When the protective cover 24 reaches the detection end of the detection probe 12, the plug-in blocks 25 on both sides of the protective cover 24 insert into the limiting holes of the top limiting blocks 27 on both sides of the detection probe 12, and the rubber protrusion 26 is pressed against one side of the limiting hole. The elasticity and friction of the rubber protrusion 26 lock the protective cover 24 and the detection probe 12, effectively preventing dust and other contaminants from adhering to the metal contacts of the detection end of the detection probe 12, ensuring the accuracy and stability of data transmission during subsequent testing.

[0031] When performing vehicle testing, before inserting the test probe 12, the operator presses the linkage plate 34. The connecting rod 31 rotates around the support base 3 fixed on the surface of the test probe 12, overcoming the elastic force of the spring 33 to move the pressing block 32 away from the rectangular hole of the test probe 12, making it easier for the probe to be inserted into the diagnostic interface. After the test probe 12 is fully inserted, the linkage plate 34 is released, the spring 33 returns to its original deformation, and the elastic force through the rotating rod 31 causes the pressing block 32 to pass through the rectangular hole and press against the diagnostic interface, realizing the self-locking of the test probe 12 on the diagnostic interface, preventing the test probe 12 from becoming loose at the diagnostic interface, and improving the stability of the test probe 12 during the testing process.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
