The utility model discloses a speed reducing mechanism for an automatic change-over switch and the automatic change-over switch, and relates to the technical field of low-voltage electric appliances. The speed reduction mechanism for the automatic change-over switch comprises a speed reduction wheel and a rocker, the speed reduction wheel is movably arranged on an output shaft of an operating mechanism of the automatic change-over switch in a sleeving mode, a speed reduction rail is arranged on the speed reduction wheel, and the rocker is connected with the speed reduction wheel. The output part of the operating mechanism is abutted against the speed reduction wheel after running for a certain idle stroke, the speed reduction wheel is forced to rotate, and the rocker is driven to move along the speed reduction track to decelerate rotation of the output shaft. The speed reducing mechanism for the automatic change-over switch and the automatic change-over switch can solve the problem of power supply short circuit caused by too fast switching of the moving contact between the common closing position and the standby closing position in the prior art.

The invention discloses a crossing intention judgment method, a medium, equipment and a vehicle. The crossing intention judgment method comprises the following steps: constructing a data set by using a vulnerable road user crossing positive example meeting a first preset condition and a vulnerable road user crossing negative example meeting a second preset condition; wherein the first preset condition is that the vulnerable road user has a passing behavior in front of the vehicle in the region of interest of the vehicle in the future preset time; the second preset condition is that the vulnerable road user is in the region of interest of the vehicle and has a passing behavior behind the vehicle in the future preset time; training a preset dichotomy model by adopting the data set, wherein the dichotomy model is built based on a deep learning model; and deploying the trained dichotomy model to the automatic driving system so as to judge the crossing intention of the vulnerable road user. Through the above mode, the judgment accuracy of the crossing intention of the vulnerable road user can be improved, and then the safety and comfort of passengers are improved.

This utility model relates to the field of sheet metal removal and discloses a sheet metal removal mechanism, including a mechanism body. A second motor is fixedly connected to the bottom inner wall of the mechanism body, and a fixed column is fixedly connected to the drive end of the second motor. A gear is fixedly connected to the outer wall of the fixed column, and a locking component is provided on the outer wall of the gear. The gear clamps the sheet metal through the locking component. A first motor is fixedly connected to the right inner wall of the mechanism body, and the drive end of the first motor passes through the mechanism body and is fixedly connected to a rotating column. A first sprocket is fixedly connected to the outer wall of the rotating column, and a chain is meshed with the outer wall of the first sprocket. The chain is used to move the sheet metal outward. In this utility model, the locking component allows the mechanism to unfold and then reverse to clamp the left and right sides of the sheet metal, achieving adaptive clamping of sheets of different widths and avoiding limitations due to length differences.

This invention discloses an adaptive transmission method for trunked intercom based on wireless local area networks (WLANs), comprising the following steps: collecting link-state and service-state indicators to form a state vector; calculating the carrying window and delay budget using sliding window statistics and exponential weighting, generating a resource profile including congestion and risk levels; layering voice frames and labeling key frames with the latest delivery timestamp; selecting representative terminals for group clustering based on access point identifier, channel, and link quality; and generating transmission parameters by calling an improved BBRv3 under resource profile constraints in the unicast pipeline; prioritizing the transmission of key frame copies, aggregating completion summaries, determining majority completion, and retransmitting missing key frames with targeted compensation and updating completion; switching the distribution mode and performing gray-scale rollback when delay exceeds limits, busy-occupancy surges, or roaming occurs; recording indicator and parameter versions, establishing a template library through scenario fingerprint matching, and storing versioned data. This invention improves the reliability of key voice delivery and reduces the risk of delay jitter and packet loss under congestion and roaming conditions.
