[0002] CAN bus is a serial data communication bus with a communication rate of up to 1Mb / s. Data can be exchanged between different buses using a data transmitter so that other devices can use it.

[0003] The interface of a commonly used data transmitter is exposed on the outside, and the transmission interface of the data transmitter is welded on the circuit board inside the data transmitter. When the interface of the data transmitter collides with an external object, the collision force will be transmitted to the circuit board inside the data transmitter through the interface, causing damage to the circuit board inside the data transmitter, making the data transmitter unable to be used normally, and water vapor in the outside air will enter the interface, causing corrosion to the interface, reducing the storage time of the data transmitter.

[0005] To achieve the above-mentioned purpose, a CAN bus data transmitter is provided, comprising: a transmitter body, the transmitter body comprising a CAN bus interface and a LIN bus interface, a protective mechanism is installed on the outer end of the transmitter body, and the transmitter body is located in the middle of the protective mechanism, and a connecting plate is fixedly connected to the outer end of the protective mechanism; the protective mechanism comprises a shell, a first protective shell, a first placement groove, a second placement groove and a second protective shell, two shells are provided, and the transmitter body is located in the two shells, the connecting plate is fixedly connected to the outer end of the shell, and the connecting plate is located at the opposite ends of the two shells, the two shell side walls are respectively provided with a first placement groove and a second placement groove, and the first placement groove and the second placement groove are respectively facing the transmitter body, the first placement groove and the second placement groove are communicated, and the transmitter body extends into the first placement groove and the second placement groove, the first protective shell and the second protective shell are respectively fixedly connected to the side ends of the two shells, and the first protective shell and the second protective shell are far away from each other, the first protective shell is communicated with the first placement groove, and the LIN bus interface is located in the first protective shell, the second protective shell is communicated with the second placement groove, and the CAN bus interface is located in the second placement groove. It can protect the interface of the data transmitter and disperse the impact force to the surface of the data transmitter when the interface is hit, avoiding damage to the circuit board inside the data transmitter and ensuring the normal use of the data transmitter. It can also isolate the water vapor in the outside air from the interface to avoid corrosion of the interface of the data transmitter and extend the storage time of the data transmitter.

[0006] According to the CAN bus data transmitter, the side end of the connecting plate is installed with a connecting bolt, and the two shells are fixedly connected by the connecting plate and the connecting bolt, so that the protective mechanism can be easily disassembled from the surface of the data transmitter, so that the data transmitter can be used, which is convenient for the staff to use.

[0007] According to the CAN bus data transmitter, the outer end of the protection mechanism is fixedly connected with a buffer block with an L-shaped cross section, and the buffer block is located at the upper and lower ends of the shell, so as to further improve the protection effect of the data transmitter and enhance the collision strength that the shell can withstand.

[0008] According to the CAN bus data transmitter, the buffer block is made of sponge material, which improves the buffering effect of the data transmitter when it is hit, reduces the weight of the data transmitter, and facilitates transportation.

[0009] According to the CAN bus data transmitter, the housing, the first protective shell and the second protective shell are made of plastic, and the housing, the first protective shell and the second protective shell are integrally formed by injection molding, thereby ensuring the integrity and structural strength of the protective mechanism, improving the impact resistance of the protective mechanism and improving the efficiency of installation on the data transmitter.

[0010] The above scheme has the following beneficial effects:

[0011] 1. The interface of the CAN bus data transmitter is protected by a protective mechanism. When the interface is hit, the impact force is dispersed to the surface of the data transmitter to avoid damage to the circuit board inside the data transmitter, ensuring the normal use of the data transmitter. The water vapor in the outside air is isolated from the interface to avoid corrosion of the interface of the data transmitter, further extending the storage time of the data transmitter.

[0012] 2. The buffer block on the outer end frame of the shell plays a buffering role when the corners of the data transmitter are hit during transportation, thereby preventing the shell from being damaged and improving the protection effect of the transmitter body.
