Description

Technical Field

[0001] The invention relates to the technical field of electronic pedal auxiliary detection, and in particular to an electronic pedal bracket used for an automobile engine test bench. Background Art

[0002] As we all know, as one of the main control devices of a car, the quality of the electronic pedal determines the safety of car driving to a certain extent. In order to ensure the quality of the electronic pedal after production, the electronic pedal is usually tested after production. To facilitate the testing of the electronic pedal, an electronic pedal bracket for an automobile engine test bench is proposed.

[0003] After searching, the Chinese invention patent with publication number CN111103142B, which was authorized and announced on August 31, 2021, discloses an electronic pedal bracket for a plug-in hybrid vehicle engine test bench, which is roughly described as including a base, and threaded holes are opened at the four corners of the upper surface of the base. The device is locked on the engine test bench through the threaded engagement of the threaded holes and the bolts. A support plate is welded to the center position of the top of the base, and one end of a reinforcing rib is welded on both sides of the left and right sides of the top of the rear side of the support plate. The stability between the support plate and the base is improved by the reinforcing ribs. The other ends of the two reinforcing ribs are respectively welded to the left and right ends of the rear side of the top of the base, and a support seat is welded to the top of the support plate. The support plate is located on the rear side of the bottom end of the support seat. When in use, the device is installed on the engine test bench through the threaded engagement of the threaded holes and the bolts. When the electronic pedal of the car needs to be disassembled, it is connected The external power supply cylinder of the cylinder starts to work, and the cylinder drives the first push plate to move upward. Since the rectangular plate is connected to the support plate by a pin shaft, the spring drives one end of the rectangular plate to rotate inward under the action of its own tension, and the other end of the rectangular plate drives the clamping plate to rotate outward through the arc plate until the two second push plates contact, thereby realizing the disassembly of the automobile electronic pedal. When the automobile electronic pedal needs to be installed, the external power supply cylinder of the cylinder is connected to start working. Since the contact surface between the first push plate and the second push plate is an inclined surface, the cylinder drives the first push plate to move downward while driving one end of the rectangular plate to rotate outward, and the other end of the rectangular plate drives the arc plate to drive the clamping plate to rotate inward to clamp the automobile electronic pedal. Due to the socket connection between the column and the clamping plate, the two columns will rotate according to the inclination of the left and right sides of the automobile electronic pedal, thereby improving the fixity of the device on the automobile electronic pedal and realizing the installation of the automobile electronic pedal.

[0004] Although the above-mentioned prior art solution can be applied to the auxiliary installation and positioning during the detection process of the automobile electronic pedal, and improves the work efficiency of the installation and removal of the automobile electronic pedal to a certain extent, due to the wide variety of automobile electronic pedals, electronic pedals of different specifications will inevitably have different shapes and sizes.
