[0002] The CAN module is an intelligent electronic control device that realizes communication data forwarding between the electronic control devices of the whole vehicle, thereby realizing a regional network control system for the on-board electronic control devices of the whole vehicle. It adopts a powerful 16-bit microcontroller with two CAN controllers, which can be applied to both high-speed and low-speed CAN bus networks.

[0003] For example, a new type of CAN communication module with application number 202221453620.7, this utility model can seal the joint between the sealing cover and the module substrate through the design of rubber strips, avoid the problem of external water stains interfering with the CAN communication module body, and ensure the normal use of the vehicle. When the CAN communication module body is cooled by an external fan or other device, the cooling airflow can be captured by the wind collector, and then transported to the inner cavity of the cooling pipe through the air guide bend. The function of rapid cooling of the CAN communication module body is achieved through the design of heat-absorbing fins, graphene bonding sheets and tree-shaped heat dissipation fins. However, the device does not provide targeted protection at the pins, and the pins of the CAN communication module are easily interfered by the outside world. The device is protected and dissipated on the outside of the whole, which has a high manufacturing cost, occupies space, and is not easy to install.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-interference CAN communication module is proposed. Utility Model Content

[0021] like Figure 1-Figure 4 As shown, an anti-interference CAN communication module includes a module body 1 and a cover body 2 arranged on the upper surface of the module body 1, a plurality of pins 3 are arranged on the outer surfaces of both sides of the module body 1, a spring shaft 4 is arranged on the outer surface of the cover body 2 outside the pins 3, a protective cover 5 is fixedly connected to the outer cylindrical surface of the spring shaft 4, a replacement mechanism 6 is arranged outside the spring shaft 4, the replacement mechanism 6 includes a plurality of slide grooves 61 opened on the upper surface of the cover body 2, a slider 62 is slidably connected inside the slide groove 61, a substrate 63 is fixedly connected to the outer surface of the slider 62, and the outer surface of the substrate 63 is fixedly connected to the outer cylindrical surface of the spring shaft 4, the slide groove 61 is T-shaped, the slider 62 is T-shaped, the substrate 63 is rectangular, and fixed screw grooves 7 are opened at four vertex positions on the upper surface of the cover body 2, and the inside of the fixed screw groove 7 extends to the module body 1 is connected with a fixing screw 8 on the internal thread, a plurality of heat dissipation fins 9 are fixedly connected to the upper surface of the cover body 2, and the lower end of the heat dissipation fin 9 extends to the inside of the cover body 2 and is fixedly connected with a heat conducting plate. The heat dissipation fin 9 is made of aluminum, which controls the cost while improving the heat dissipation rate. When the module body 1 is installed, the slider 62 can be slid into the inside of the slide groove 61, and the protective cover 5 can protect the pin 3 of the module body 1 to prevent external factors from interfering with the normal operation of the module body 1. During inspection and maintenance, the protective cover 5 on the spring shaft 4 can be rotated to expose the pin 3 to avoid the influence of the protective cover 5 on the inspection and maintenance. If the elastic function of the spring shaft 4 is weakened or the protective cover 5 is damaged, the slider 62 inside the slide groove 61 can be slid out to realize the rapid replacement of vulnerable parts. The fixing screw 8 inside the fixing screw groove 7 facilitates the disassembly of the cover body 2, and the heat dissipation fins 9 can improve the heat dissipation efficiency.

[0022] like Figure 2As shown, threaded seats 10 are fixedly connected to the outer surfaces of both sides of the cover body 2 , the interior of the threaded seat 10 extends to the outside and is threadedly connected to a threaded rod 11 , and the interior of the threaded seat 10 is provided with threads corresponding to the exterior of the threaded rod 11 .

[0023] Furthermore, a knob 12 is fixedly connected to the upper end of the threaded rod 11, and a heightening plate 13 is rotatably connected to the lower end of the threaded rod 11. The lower surface of the heightening plate 13 is made of a flexible material to prevent scratching of the circuit board.

[0024] Working principle: When using the anti-interference CAN communication module, first, when the module body 1 is installed, the slider 62 can be slid into the inside of the slide groove 61, and the protective cover 5 can protect the pin 3 of the module body 1 to prevent external factors from interfering with the normal operation of the module body 1. During detection and maintenance, the protective cover 5 on the spring shaft 4 can be rotated to expose the pin 3 to avoid the protective cover 5 from affecting the detection and maintenance. If the elastic function of the spring shaft 4 is weakened or the protective cover 5 is damaged, the slider 62 inside the slide groove 61 can be slid out to achieve rapid replacement of vulnerable parts. The fixing screws 8 inside the fixing screw groove 7 facilitate the disassembly of the cover body 2, and the heat dissipation fins 9 can improve the heat dissipation efficiency. After the pin 3 is welded, the module body 1 is suspended and close-fitting. The suspension stability is poor, and close-fitting is not convenient for heat dissipation. Before and after welding, the threaded rod 11 can be rotated by the knob 12, and the pad 13 can be against the circuit board to lift the entire module body 1, improving stability while performing suspended heat dissipation. This is the working principle of the anti-interference CAN communication module.
