The invention relates to an automatic travel adjusting structure for a press in the technical field of presses. The automatic travel adjusting structure comprises a crankshaft; an eccentric shaft neck of the crankshaft is sleeved with an eccentric bushing capable of rotating axially along the eccentric shaft neck; and one end of the eccentric bushing is provided with a locking device, and the other end of the eccentric bushing is provided with an eccentricity adjusting device. According to the automatic travel adjusting structure, the eccentric bushing is connected with the crankshaft through the locking device and the eccentricity adjusting device, and the pressing motion and travel adjusting motion of the press are realized through rotation of the crankshaft; and during travel adjustment, the power for relative rotation of the eccentric bushing and the crankshaft comes from the rotating crankshaft, so that the travel of the press is convenient to adjust in a labor-saving mode, and is automatically adjusted through the rotation of the crankshaft, the automatic travel adjusting structure is suitable for automatically, synchronously and accurately adjusting the travel of a single point press, a double-point press or a four-point press, and the application range of the press is widened.

The invention discloses a parameter output method, device and storage medium of an amphibious vehicle. The method includes the following steps: acquiring the measured subsidence and deformation of the wheel and the driving state of the amphibious vehicle; according to the measured subsidence, the measured deformation and the predicted Set the first threshold value to obtain the road surface on which the wheels are driving, wherein the road surface includes hard road surface or soft road surface; according to the driving state, the road surface and the preset soil parameter library, the first output parameter is obtained through the soft road surface estimation mode, Or according to the driving state and the road surface, the second output parameter is obtained through the hard road surface estimation mode; and the parameter output is performed according to the first output parameter or the second output parameter. According to the present invention, different modes can be used for estimation according to different road surfaces and driving states, thereby ensuring the accuracy of the estimation results. The invention can be widely used in the technical field of amphibious vehicles.

The invention discloses an ink key driving device for a printer. The driving device comprises a handspike and a handspike driving device, wherein, the handspike driving device comprises a plane cam and a manual zero adjusting unit or self regulating unit; the end of the handspike is up against the drive surface of the plane cam, and the plane cam is connected with the manual zero adjusting unit and the self regulating unit. The ink key driving device can precisely adjust the gap between an ink key and an ink fountain roller, thereby realizing precise automatic adjustment of the amount of jetted ink, and is completely suitable for being used on printers.

The invention provides a binocular head-wearing display device and a method thereof for adjusting image spacing, which belongs to the technical field of head-wearing display. The binocular head-wearing display device can solve the problems of the prior art of complicated operation for image spacing adjustment and poor display effects and viewing experience. The binocular head-wearing display device comprises two display units, an image acquisition unit and an interpupillary distance analysis unit, wherein the two display units are respectively used for generating test images and display images for the left eye and the right eye of a user, the two test images respectively have a test mark, and the spacing between the two test marks is gradually increased or gradually reduced; the image acquisition unit is used for acquiring images in both eyes of the user, and the interpupillary distance analysis unit is used for getting the critical moment when the interpupillary distance changes according to images in the eyes of the user when the user watches the test images and determining the image spacing according to the spacing between the two test marks at the critical moment. In addition, the critical moment is a moment that the interpupillary distance stops increasing gradually and becomes stable or a moment that the interpupillary distance stops being stable and starts to reduce gradually.

The invention discloses an automatic adjusting device of a press die of a collar press and the collar press. The automatic adjusting device comprises an adjusting driving part, an adjusting rod and adetecting part. The adjusting driving part is connected to the adjusting rod. The adjusting rod is used for being connected with a movable die plate of the collar press. The adjusting driving part candrive the movable die plate to move by driving the adjusting rod to move so as to adjust the distance between the movable die plate and a fixed die plate. The detecting part is used for being arranged on the movable die plate or the fixed die plate and used for detecting the distance between the movable die plate and the fixed die plate. The automatic adjusting device of the press die of the collar press is accurate in distance adjusting and saves time and labor.

The invention discloses an information collection device, an electronic device and a method. The information collection device is rotatably arranged on the electronic device and comprises a rotation shaft, an information collection unit and a control unit. The rotation shaft comprises a first end and a second end opposite to the first end. The information collection unit is fixedly connected with the first end. The control unit is connected with the second end. When the control unit receives a first trigger signal, the control unit generates and executing an angle adjusting command, so that the rotation shaft is driven to rotate, and the information collection unit is driven to be adjusted to the second angle different from a current first angle from the current first angle. By means of the information collection device, the electronic device and the method, the technical problem that in the prior art, the angle of the information collection device integrated with the electronic device is fixed and can not be automatically adjusted is solved.

The invention relates to a terminal control method and a terminal control system based on audio signals. The terminal control method comprises that: a terminal detects the audio signals in real time or periodically; when the detected audio signal is a mixed audio signal, the terminal extracts the signal according to a preset frequency, and determines the frequency of the extracted audio signal; the terminal obtains an operating parameter or an adjustment rule corresponding to the determined frequency of the audio signal according to mapping relation between the preset audio signal frequency and the operating parameter or mapping relation between the preset audio signal frequency and the adjustment rule; the terminal operates according to the obtained operating parameter or adjusts the parameter according to the obtained adjustment rule. The invention also discloses a terminal control method based on audio signals. The terminal control method and system based on audio signals are very simple and convenient to implement, improves the automatic adjustment efficiency of the operating parameters of the terminal, and meanwhile does not needs to be added with other receiving devices, thus being low in cost.
