Description

Technical Field

[0001] The utility model relates to the technical field of network management controllers, in particular to a multi-channel CAN and LIN gateway controller. Background Art

[0002] With the rapid development of in-vehicle network technology, traditional vehicles, autonomous vehicles, and future driverless cars are generally equipped with complex in-vehicle network systems. The in-vehicle gateway controller is a core component in the vehicle's electrical and electronic architecture. As the data exchange hub for the entire vehicle network, it is responsible for coordinating protocol conversion, data exchange, and fault diagnosis between the CAN bus network with different structural characteristics and other data networks.

[0003] However, the existing network management controller is relatively cumbersome to fix when in use. It is usually fixed to the vehicle with a snap-on method, which is easy to loosen. At the same time, it cannot be quickly disassembled for maintenance later, which causes inconvenience to the staff. In addition, the network management controller itself is relatively cumbersome. To address the above problems, a solution is proposed below. Utility Model Content

[0004] The utility model aims to provide a multi-channel CAN and LIN gateway controller, which has the advantages of being easy to fix and disassemble, having a simple structure and high practicality.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A multi-channel CAN and LIN gateway controller includes a controller housing, a removable shell cover is provided at the front end of the controller housing, a plurality of limit clamps are formed on the outside of the controller housing, and a plurality of mounting seats are also provided on the outside of the controller housing, one end of the mounting seat is located on the inner side of the two limit clamps, a limit mechanism is also provided on the controller housing, and the limit mechanism cooperates with the controller housing, the limit mechanism includes a plurality of limit columns passed through the controller housing, a limit hole is provided on one side of the mounting seat, and the top of the limit column is passed through the limit hole, a movable plate is provided in the controller housing, the movable plate is fixedly connected to the other end of the limit column, and the movable plate is connected to the inner wall of the controller housing by a plurality of reset springs, a plurality of heat dissipation holes are provided at the upper end of the controller housing, and a detachable filter is also attached to the inner top of the controller housing, and the filter is located on one side of the plurality of heat dissipation holes.

[0007] Preferably, the shell cover is connected to a plurality of elastic hooks, the controller housing is provided with a plurality of fixing holes, and the controller housing and the shell cover are fixedly connected via the plurality of elastic hooks and the fixing holes.

[0008] Preferably, the outer side of the filter is connected to a plurality of fixing plates, the inner top of the controller housing is fixed with a plurality of fixing columns, and the plurality of fixing plates are respectively embedded in the fixing columns.

[0009] Preferably, a mounting hole is provided on the other side of each mounting seat.

[0010] Preferably, a wiring harness connection port is also provided on the shell cover.

[0011] The beneficial effects of the utility model are:

[0012] 1. The cover and the controller housing can be fixed by snapping several elastic hooks into the fixing holes. Similarly, the elastic hooks can be pressed out of the fixing holes to realize the disassembly of the controller housing and the cover. Finally, the controller housing and the cover can be quickly disassembled and installed to facilitate the inspection and maintenance of the controller.

[0013] 2. By pressing the limit post inward, the limit post can be made to slide inward along the controller housing, thereby driving the movable plate to move backward. At this time, several return springs are stretched to generate elastic force, and then the controller housing can be inserted into the mounting seat, that is, the mounting seat is located on the inner side of the two limit clamps. Then the limit hole can be located in front of the limit post, and finally the limit post can be driven back to the initial position by the reset action of the return spring, so that the limit post is pushed into the limit hole, thereby fixing the controller housing. Conversely, when the limit seat is detached from the limit hole, the controller housing can be quickly disassembled, and finally the controller can be quickly disassembled and installed, which greatly saves the installation and maintenance time of the staff, and is convenient for popularization and use.

[0014] 3. Several heat dissipation holes can dissipate heat for the circuit boards and components installed inside the controller housing, thereby increasing the service life of the controller. The filter can also prevent external dust and other impurities from entering the controller housing. BRIEF DESCRIPTION OF THE DRAWINGS

The shell cover 2 and the controller housing 1 can be fixed by snapping the plurality of elastic hooks 12 into the fixing holes 13. Similarly, the elastic hooks 12 can be pressed out of the fixing holes 13 to realize the disassembly between the controller housing 1 and the shell cover 2, and finally the controller housing 1 and the shell cover 2 can be quickly disassembled and installed to facilitate the inspection and maintenance of the inside of the controller.

[0022] Several limiting clamps 3 are formed on the outside of the controller housing 1, and several mounting seats 4 are also provided on the outside of the controller housing 1. A mounting hole 16 is opened on the other side of each mounting seat 4. The mounting seat 4 can be installed through the mounting hole 16.
