Description

Technical Field

[0001] The present invention relates to the technical field of CAN bus fault detection devices, in particular to a portable CAN bus fault detection device and a detection method thereof. Background Art

[0002] CAN (Controller Area Network) is a serial communication protocol bus for real-time applications. It can use twisted-pair cables to transmit signals and is one of the most widely used fieldbuses in the world. Developed by Robert Bosch of Germany, the CAN protocol is used for communication between various components in automobiles, replacing expensive and bulky distribution wiring harnesses. The robustness of the protocol has extended its use to other automation and industrial applications. Features of the CAN protocol include complete serial data communication, real-time support, a transmission rate of up to 1Mb / s, 11-bit addressing, and error detection. The CAN bus is a multi-master serial communication bus. The basic design specifications require high bit rates, high immunity to electronic interference, and the ability to detect any errors. The CAN bus can be used in automotive electrical control systems, elevator control systems, safety monitoring systems, medical equipment, textile machinery, and ships.

[0003] Most of the existing CAN bus fault detection devices do not have a portable mechanism on the outside, which means that the operators need to manually carry the detection devices during the transportation process. For long distances, the operators need to consume more physical strength, which increases the inconvenience and tediousness of moving the detection devices. At the same time, the display screens of most existing CAN bus fault detection devices are directly exposed to the outside world. Accidental collisions during the later movement will often cause scratches on the surface of the display screen, which not only affects the aesthetics of the surface, but also affects the clarity of the operator's later viewing.

The U-shaped limit rod is located on one side of another group of C-shaped clamping plates.

[0015] A method for using a portable CAN bus fault detection device, the steps of use are as follows:

[0016] During use, the operator can first take the CAN bus fault detector and insert it into the inner part of the two sets of C-shaped clamping plates on the adjacent side, and then rotate the two-way threaded rod to drive the two sets of internal threaded sleeves to move away from each other on the outside, so that the internal threaded sleeve can drive the internal threaded sleeve to move hingedly, and then the C-shaped clamping plate and the above components can be pulled by the hinged rod to drive the limiting opening slot to move closer to the outside of the limiting plate, thereby completing the assembly function of the C-shaped clamping plate and the above components with the CAN bus fault detector, so as to facilitate the later operator to realize the portable operation of the CAN bus fault detector. At the same time, when the C-shaped clamping plate and the CAN bus fault detector are installed and fixed, take the L-shaped protective plate, insert it and slide it to the inside of the limiting slide slot to complete the protection operation of the screen and interface on the surface of the CAN bus fault detector. Finally, the structural design of the baffle can realize the limiting operation of the L-shaped protective plate to prevent it from falling.

[0017] Finally, the connecting plate is released and driven by the elastic restoring force of the spring to engage with the other set of U-shaped limit rods and the inside of the card slot one, so as to realize the fixing operation of the adjusted sleeve plate and the sleeve plate;

[0018] When it is necessary to move the components above the CAN bus fault detector in the later stage, the limiting work on the sleeve plate and the sleeve plate can be released by pulling the connecting plate, and the sleeve plate and the components above the sleeve plate and the CAN bus fault detector are in a horizontal state through the reverse movement of the above steps. At the same time, the sleeve plate is pulled out to the inside of the sleeve plate to release the storage operation, which can facilitate the operator to pull and transfer the CAN bus fault detector, thereby realizing the portability function of the CAN bus fault detector in the later use;

[0019] Step three: disengage the fastening bolts to the inside of the internal threaded hole, and then pull the sleeve plate to rotate on the outside of the U-shaped limit rod 2 to achieve vertical operation with the CAN bus fault detector, and then cooperate with the sleeve plate to achieve the support and lifting function of the CAN bus fault detector during use. Finally, by the reverse movement of the fastening bolts and the reverse rotation of the sleeve plate, it is horizontal with the CAN bus fault detector, and then through the cooperation of the supporting clamping assembly and the above components, the pulling and moving operation of the CAN bus fault detector can be realized.

[0020] Compared with the prior art, the present invention provides a portable CAN bus fault detection device with the following beneficial effects:

[0021] 1. The present invention realizes the assembly function of the external portable mechanism and the CAN bus fault detector through the structural design of the C-shaped clamping plate and the adjustment and fixing assembly and the above components, so that the operator rotates the bidirectional threaded rod and then realizes the close clamping work of the two sets of C-shaped clamping plates through the structural design of the internal threaded sleeve and the hinged rod, thereby completing the assembly of the C-shaped clamping plate and the above components with the CAN bus fault detector. The structural design of the component allows the operator to only perform one thread rotation work, which effectively improves the convenience of disassembly and assembly. At the same time, through the mutual cooperation of the limiting slide groove and the L-shaped protective plate, the screen outside the CAN bus fault detector can also be protected, effectively preventing the screen from being scratched by accidental collisions in the future, thereby ensuring the clarity of the screen viewing in the future.

[0022] 2.

[0046] A method for using a portable CAN bus fault detection device, the steps of use are as follows:

[0047] When in use, the operator can first take the CAN bus fault detector 1 and insert it into the inner part of the two groups of C-shaped clamping plates 7 close to each other, and then rotate the two-way threaded rod 504 to drive the two groups of internal threaded sleeves 503 to move away from each other on the outside, so that the internal threaded sleeve 503 can drive the internal threaded sleeve 503 to hinge and move, and then the C-shaped clamping plate 7 and the above components can be pulled by the hinged rod 502 to drive the limiting opening slot 501 to move closer to the outside of the limiting plate 500, thereby completing the assembly function of the C-shaped clamping plate 7 and the above components with the CAN bus fault detector 1, so as to facilitate the later operator to realize the portable operation of the CAN bus fault detector 1. At the same time, after the C-shaped clamping plate 7 and the CAN bus fault detector 1 are installed and fixed, take the L-shaped protective plate 8 and insert it into the inside of the limiting slide groove 2 to complete the protection operation of the screen and the interface on the surface of the CAN bus fault detector 1. Finally, the structural design of the baffle can realize the limiting operation of the insertion of the L-shaped protective plate 8 to prevent it from falling.

[0048] Step 2: By pulling the connecting plate 306, the two sets of clamping rods 304 are driven to move inside the clamping slot 2 303 and the clamping slot 1 300 respectively to achieve the stretching work of the spring 305. At this time, the movement of the clamping rod 304 can release the limit of the sleeve plate 301 and the above components and the fixing work of the sleeve plate 307. Then the operator rotates the sleeve plate 301 and the above components outside the U-shaped limit rod 1 302, so that the sleeve plate 301 can achieve vertical work with the CAN bus fault detector 1, so as to facilitate the later The support and lifting work of the CAN bus fault detector 1 during use is realized to improve the comfort of use. At the same time, the sleeve plate 301 can be vertically contacted with the ground to push the sleeve plate 307 upward inside the sleeve plate 301 through the roller 4 to realize the storage function of the roller 4. Finally, the connecting plate 306 is released and the elastic restoring force of the spring 305 drives it to be inserted into another set of U-shaped limit rods 302 and the slot 300, so as to realize the fixing operation of the adjusted sleeve plate 301 and the sleeve plate 307.

[0049] When it is necessary to move the components above the CAN bus fault detector 1 in the later stage, the limiting work on the sleeve plate 301 and the sleeve plate 307 can be released by pulling the connecting plate 306. After the reverse movement of the above steps, the sleeve plate 301 and the components above are in a horizontal state with the CAN bus fault detector 1. At the same time, the sleeve plate 307 is pulled out to the inside of the sleeve plate 301 to release the storage operation, which can facilitate the operator to pull and transfer the CAN bus fault detector 1, thereby realizing the portability function of the CAN bus fault detector 1 in the later use.

[0050] Step three: By rotating the fastening bolt 601 to disengage it from the inside of the internal threaded hole 602, and then by pulling the sleeve plate 600 to rotate outside the U-shaped limit rod 2 603, it can realize its vertical operation with the CAN bus fault detector 1, and then by cooperating with the sleeve plate 301, the support and lifting function of the CAN bus fault detector 1 during use can be realized. Finally, by the reverse movement of the fastening bolt 601 and the reverse rotation of the pulling sleeve plate 600, it is made horizontal with the CAN bus fault detector 1, and then by cooperating with the supporting clamping assembly 3 and the above components, the pulling and moving operation of the CAN bus fault detector 1 can be realized.

[0051] In summary: when in use, the operator can first take the CAN bus fault detector 1 and insert it into the inner part of the two groups of C-shaped clamping plates 7 close to each other, and then adjust the structural design of the fixing component 5 to achieve the close clamping work of the two groups of C-shaped clamping plates 7, thereby completing the assembly function of the C-shaped clamping plates 7 and the above components with the CAN bus fault detector 1, so as to facilitate the later operator to realize the portable operation of the CAN bus fault detector 1. At the same time, when the C-shaped clamping plate 7 and the CAN bus fault detector 1 are installed and fixed, take the L-shaped protective plate 8 and insert it into the inner part of the limiting slide groove 2 to complete the installation of the CAN bus fault detector 1. Protective operations are performed on the screen and interface on the surface, and finally, the structural design of the baffle can realize the limit operation of the L-shaped protective plate 8 to prevent it from falling, and then through the structural design and adjustment of the supporting clamping component 3 and the supporting pulling component 6, the lifting and supporting work of the CAN bus fault detector 1 during use can be realized, thereby improving the comfort of use, and the pulling and moving function of the CAN bus fault detector 1 can be realized when not in use, so that the CAN bus fault detector 1 can be pulled and transferred by the operator like a suitcase, without the operator manually carrying it, so as to reduce the operator's physical exertion and improve the portability of the CAN bus fault detection device.
