The driving slider 323 is provided with the driving slot 322, and is slidably engaged with the driving rail 3312 of the driven slider 331 through the driving slot 322.
A user can hold the portion of the push-pull rod 324 located outside the tray body 11 by hand to drive the push-pull rod 324 to move back and forth along the first direction, so that the push-pull rod 324 drives the driving slider 323 to move back and forth along the first direction, the driving slider 323 is slidably engaged with the driving slide rail 3312 of the driven slider 331 through the driving engaging slot 322, and the driven slider 331 and the slide rod 332 are driven to move back and forth along the second direction, thereby adjusting the inclination angle formed by the operation panel 101 and the placement surface.
It should be noted that the present invention has been further described only by using the driving cylinder 311 and the telescopic rod 312, the driving motor 313 and the lead screw 314, and the push-pull rod 324 as the power source for driving the driving member 32 to move back and forth along the first direction, which is not exhaustive, and other embodiments capable of driving the driving member 32 to move back and forth along the first direction are within the scope of the present invention.
Referring to fig. 7, in an alternative embodiment, the driving part 32 does not need to be provided with the driving slot 322, and the driven slider 331 does not need to be provided with the driving slide rail 3312. In this embodiment, the active part 32 includes a first driving ramp 325, and the passive slider 331 includes a second driving ramp 3313.
Referring to fig. 8, the driving source 31 further includes a fixing base 34 and a restoring member 35, the fixing base 34 is fixedly disposed on the tray body 11, one end of the restoring member 35 is connected to the fixing base 34, and the other end is connected to the sliding rod 332.
When the driving cylinder 311 drives the telescopic rod 312 to extend, the telescopic rod 312 drives the driving member 32 to move away from the driving cylinder 311 along the first direction, the first driving inclined surface 325 of the driving member 32 presses against the second driving inclined surface 3313 of the driven member 33, the driven member 33 and the sliding rod 332 are driven to move away from the driving member 32 along the second direction, and the sliding rod 332 drives the reset member 35 to accumulate the reset force.
When the driving cylinder 311 drives the telescopic rod 312 to shorten, the telescopic rod 312 drives the driving member 32 to move close to the driving cylinder 311 along the first direction. In the process, the driving member 32 leaves a retraction space for the driven slider 331, and the reset member 35 gradually releases the reset force to drive the sliding rod 332 and the driven slider 331 to move close to the driving member 32 in the second direction.
Therefore, by adding the reset member 35 to this embodiment, the driving member 32 and the driven member 33 can move back and forth along the second direction without sliding engagement between the driving slot 322 and the driving rail 3312.
It should be noted that the above-mentioned returning element 35 may be an elastic element, and then the corresponding returning force is an elastic force. Or, the restoring element includes two magnetic attracting elements, one of which is disposed on the fixing base 34, and the other is disposed on the sliding rod 332, so that the corresponding restoring force is a magnetic force generated between the two magnetic attracting elements.
All possible combinations of the technical features in the above embodiments may not be described for the sake of brevity, but should be considered as being within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.
The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, various changes, substitutions and alterations can be made without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention should be subject to the claims.
