Description
Technical Field
[0001] This utility model relates to the field of CAN controller technology, specifically to a controller with CAN bus message function. Background Technology
[0002] Controller Area Network (CAN) is a serial communication protocol bus for real-time applications. It uses twisted-pair cables to transmit signals and is one of the most widely used fieldbuses in the world. The CAN protocol is used for communication between various components in vehicles, replacing expensive and bulky wiring harnesses. Its robustness extends its applications to other automation and industrial applications.
[0003] The controller with CAN bus message function in related technologies is designed and developed for the integration of vehicle electronic control systems. It is suitable for electronically controlled hydraulic vehicles. It consists of two parts: a controller and a data acquisition switch. When the switch detector detects that a switch is pressed, it sends a signal to the control host. The control host then operates the hydraulic valve to complete the corresponding action, saving the driver's energy and displaying the current status to the display system to inform the driver.
[0004] CAN controllers, typically installed on outdoor agricultural machinery, are housed in a control box and connected to other devices via wiring terminals. However, due to the generally harsh driving environment of these vehicles, dust can easily enter the controller from the control box, thus affecting its lifespan. To address this issue, a controller with CAN bus message functionality is proposed. Utility Model Content
[0005] In view of this, the present invention provides a controller with CAN bus message function. The present invention uses a sealing groove to engage the sealing strip, thereby sealing and fixing the top of the box body. Then, it connects the positioning bolts to the threaded holes in the receiving frame, thereby strengthening the connection and sealing between the box body and the box cover. Furthermore, the unused box body wiring ports are sealed with dustproof plates and baffles to prevent dust from entering. The wiring ports of the plug-in wires are sealed with dustproof plates and recesses, thereby improving the sealing performance of the control box and extending the service life of the CAN control board.
[0006] To solve the above-mentioned technical problems, this utility model provides a controller with CAN bus message function, including a box body at the bottom of the control box, a box cover at the top of the box body, a CAN control board at the bottom inside the box body, a sealing groove in the box wall at the top of the box body, a sealing strip adapted to the sealing groove at the bottom of the box cover, a sealing plate at the center of the bottom of the box cover, a receiving frame on the inner side of the top of the box body, a buffer plate at the bottom of the receiving frame, and multiple threaded holes embedded in the top of the receiving frame, each threaded hole passing through the box cover, and a positioning bolt in each threaded hole.
[0007] A receiving groove is provided at the wiring port at the bottom of the box. The receiving groove is used to receive the dustproof plate, thereby sealing the wiring port to prevent dust. A matching dustproof plate is provided at the top of the receiving groove. A connecting plate is provided at the top of the dustproof plate. The connecting plate is used to connect the dustproof plate to the press-type spring lock.
[0008] A press-type spring lock is provided on both the left and right sides of the receiving groove. The press-type spring lock is used to connect the receiving groove to the connecting plate. The press-type spring lock is also used to adjust the height distance between the connecting plate and the receiving groove, thereby adjusting the height distance between the dustproof plate and the receiving groove. The top of the press-type spring lock is connected to one end of the top of the connecting plate, and the bottom of the press-type spring lock is connected to the side wall of the receiving groove.
[0009] There is a slot on each of the left and right side walls of the box. The slot is used to install a dustproof heat dissipation plate. The slot is used to make the buffer panel fit with the dustproof heat dissipation plate, so that the heat inside the box can be discharged through the slot and the dustproof heat dissipation plate for heat dissipation. Each slot is equipped with a dustproof heat dissipation plate for heat dissipation inside the box. The inner surface of each dustproof heat dissipation plate is fitted with the buffer panel.
[0010] The outer surface of each dustproof heat dissipation plate is attached to the box wall of the box body. Each dustproof heat dissipation plate has a special-shaped angle iron at each of its four corners. The special-shaped angle iron is used to connect and fix the dustproof heat dissipation plate to the box wall of the box body. One end of each special-shaped angle iron is welded to the dustproof heat dissipation plate, and the other end of each special-shaped angle iron is connected to the box wall of the box body by bolts.
[0011] The bottom of the buffer panel is equipped with a buffer pad, which is used to dampen and protect the bottom of the CAN control board, thereby reducing the impact of vehicle bumps on the life of the CAN control board. The CAN control board is located on the top of the buffer pad, and several protrusions are provided on the lower surface of the buffer pad. The protrusions are used to weaken the impact force on the CAN control board during bumps.
[0012] The bottom of the dustproof plate has multiple recesses that are compatible with the wiring ports at the bottom of the box. The recesses are used to seal the gaps around the wiring ports connected to the box. Each recess has a removable baffle, which is used to seal unused wiring ports to prevent dust from entering them.
[0013] Each recess has a slot on both the left and right sides for receiving a pin. Each slot is embedded in the bottom of the dustproof plate. A positioning plate is provided at the bottom of the baffle for fixing the baffle, thereby connecting and fixing the baffle to the pin. Each baffle has a pin on both sides that matches the slot for fixing the baffle in the recess. The slot and the pin are detachably connected.
[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0015] 1. The sealing strip is engaged by the sealing groove to seal and fix the top of the box body. The positioning bolts are then connected to the threaded holes in the receiving frame to strengthen the connection and sealing between the box body and the box cover. The unused box body wiring ports are sealed with dustproof plates and baffles to prevent dust from entering. The wiring ports of the plug-in wires are sealed with dustproof plates and notches, thereby improving the sealing performance of the control box and extending the service life of the CAN control board.
[0016] 2. The CAN control board is protected on all four sides by a buffer panel, and the bottom of the CAN control board is protected by a protrusion and a buffer pad, thereby reducing the impact force on the CAN control board when it is bumped and further improving the service life of the components.

The press-type spring lock is also used to adjust the height distance between the connecting plate and the receiving groove, thereby adjusting the height distance between the dustproof plate and the receiving groove.
