Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of automobile mechanical cables, and in particular to an automobile mechanical cable driving system and a driving mechanism thereof. Background Art

[0002] At present, the gear shifter and handbrake on the car are connected to the car's power device by mechanical cables. The driver operates the lever (the gear shifter corresponds to the gear shift lever, and the handbrake corresponds to the brake lever) to drive the mechanical cable to move, thereby achieving gear shifting or handbrake braking; however, the manual operation of the lever is relatively inefficient. For this reason, existing cars usually upgrade the transmission mechanical shift system and handbrake system to an electronic automatic shift system. The electronic automatic shift system can control the drive mechanism to output power based on the driver's manual input or the body data transmitted in the car's CAN bus to drive the cable movement to automatically achieve gear switching.

[0003] An existing driving mechanism of an electronic automatic shifting system mainly includes: a support frame fixed relatively to the body of the automobile, a swing frame pivotally mounted on the support frame and connected to the end of the cable body of the mechanical cable at a position offset from the pivot axis, and a driver having an output shaft connected to the swing frame to drive the swing frame to rotate around the pivot axis.

[0004] However, the inventors found in the specific implementation that there are still a large number of existing cars on the market that use mechanical cables. If the traditional electronic automatic shift system is used to upgrade the existing cars, it is necessary to replace all the mechanical cables and other structures inside the car, which is difficult and costly. In addition, since the output shaft of the drive mechanism driver is directly connected to the swing frame, the driver and the swing frame always maintain a transmission connection state. However, when the electronic control device or driver of the electronic automatic shift system fails, causing the driver to always output power, the driver cannot manually control the driver and the swing frame to separate the transmission for maintenance, and the emergency response and safety are relatively poor.
