Example 1

An automatic turning device of the present embodiment, as shown in fig. 1, includes a housing 1, a turning mechanism 2, and a hovering mechanism 3. In the automatic turnover device of the present embodiment, the housing 1 includes an upper housing 100 and a lower housing 101 that are clamped to each other and located above and below, and the lower housing 101 has a cavity formed by extending the inner wall of the lower housing 101 for positioning and mounting each component.

The turnover mechanism 2 and the hovering mechanism 3 are respectively arranged at two ends of the shell 1; the overturning mechanism 2 and the hovering mechanism 3 are used for being connected with an overturning part; the overturning mechanism 2 can drive the overturning part to overturn, and the hovering mechanism 3 can assist the overturning part to overturn; and when the turnover part is covered, the turnover mechanism and the hovering mechanism have a damping effect on the turnover part.

In this embodiment, the turning mechanism 2 includes a motor 21, a main shaft 22, a torsion spring 23, and a turning output shaft 24. One end of the main shaft 22 is in transmission connection with the output end of the motor 21, and the other end of the main shaft 22 is in transmission connection with the turnover output shaft 24; one end of the turnover output shaft 24 extends out of the shell 1 and is used for being connected with the turnover part and driving the turnover part to turn over; the torsional spring 23 is sleeved on the main shaft 22, one end of the torsional spring 23 is fixedly connected to the main shaft 22, and the other end of the torsional spring 23 is fixedly connected to the shell 1.

Specifically, the main shaft 22 is in transmission connection with the turnover output shaft 24 through a speed change gear set 25. The speed change gear set 25 of the present embodiment includes a first gear fitted over the main shaft 22, a second gear fitted over the turnover output shaft 24, and a transmission gear meshing with the first gear and the second gear. The rotating speed transmitted to the turnover output shaft 24 by the motor 21 can be changed through the speed change gear set 25, so that the turnover output shaft 24 can output a proper rotating speed for driving the turnover part to turn over.

The torsion spring 23 is fixedly connected to the main shaft 22 through a torsion spring fixing block 26; the torsion spring fixing block 26 is fixed on the main shaft 22, and one end of the torsion spring 23 is fixedly connected to the torsion spring fixing block 26.

Moreover, the rotating direction of the torsion spring 23 compressed by the rotation of the main shaft 22 is the same as the rotating direction of the cover closing of the turnover part driven by the rotation of the main shaft 22; the rotation direction of the torsion spring 23 driven by the rotation of the main shaft 22 is the same as the rotation direction of the turnover part opened by the rotation of the main shaft 22.

In this embodiment, the hovering mechanism 3 includes a hovering output shaft 31, a second pressure spring 32, and a second moving block 33. The second moving block 33 is fixedly connected to one end of the second pressure spring 32, and the other end of the second pressure spring 32 is fixedly connected to the housing 1; the second moving block 33 is abutted against one end of the hovering output shaft 31, and the second moving block 33 is abutted against the hovering output shaft 31 through mutually matched curved surfaces; the other end of the hovering output shaft 31 extends out of the shell 1 to be connected with the overturning part and assist the overturning part to overturn.

In this embodiment, the two ends of the upper housing 101 are respectively provided with a cavity for accommodating the hovering mechanism 3 and the turning output shaft 24, and the turning output shaft 24 is connected to the main shaft 2 through the speed change gear set 25, so that the main shaft 2 and the turning output shaft 24 rotate in different axes, and the hovering output shaft 31 of the hovering mechanism 3 is connected to the turning member and the turning output shaft 24 is connected to the turning member.

The surface of the hovering output shaft 31, which abuts against the second moving block 33, is a curved surface adapted to the curved surface of the second moving block 33, and the second moving block 33 and the hovering output shaft 31 are engaged and abutted through the mutually adapted curved surfaces. In this way, when the hovering output shaft 31 rotates relative to the second moving block 33, the curved surface on the second moving block 33 and the mutually adaptive curved surface on the hovering output shaft 31 can be further adapted or mismatched, so that the second moving block 33 can move closer to the hovering output shaft 31 under the stretching action of the second pressure spring 32, or push away from the hovering output shaft 31 and compress the second pressure spring 32 under the mismatched action of the curved surface of the hovering output shaft 31.

In this embodiment, the surface of the second moving block 32 abutting against the hovering output shaft 31 is an inclined surface, the surface of the hovering output shaft 31 abutting against the second moving block 32 is an inclined surface adapted to the inclined surface of the second moving block 32, and the second moving block 32 and the hovering output shaft 31 abut against each other through mutually adapted inclined surfaces.

Moreover, the rotation direction of the hovering output shaft 31 rotating and abutting against the second moving block 33 to push the second pressing spring 32 to be compressed is the same as the rotation direction of the hovering output shaft 31 rotating to assist the turning piece to close the cover; the rotation direction of the hovering output shaft 31 rotating and enabling the second pressure spring 32 to stretch and push the second moving block 33 to move is the same as the rotation direction of the hovering output shaft 31 rotating to assist the cover opening of the turnover part.

When the automatic turnover device of this embodiment is used for driving the turnover part to rotate, one end of the turnover output shaft 24 extending out of the casing 1 and one end of the hovering output shaft 31 extending out of the casing 1 are respectively connected with two ends of the turnover part in a matching manner capable of synchronously rotating. When the cover is opened by turning, in the turning mechanism 2, the motor 21 rotates forward and drives the turning output shaft 24 to rotate through the transmission of the main shaft 22 and the speed change gear set 25, so as to drive the turning part to turn and open the cover. At this time, the torsion spring 23 is stretched to help the flip member open the cover and supply energy; in the hovering mechanism 3, the hovering output shaft 31 rotates forwards along with the synchronous overturning of the uncovering of the overturning part, and the second pressure spring 32 also stretches to help the uncovering of the overturning part and provide energy. Therefore, the turnover piece can be opened smoothly.

When the turnover part needs to be turned over to close the cover, in the turnover mechanism 2, the motor 21 rotates reversely to drive the turnover part to turn over and close the cover. At this time, the torsion spring 23 is compressed and generates a damping effect on the main shaft 22 so as to prevent the turnover part from closing the cover and storing energy; in the hovering mechanism 3, the hovering output shaft 31 rotates synchronously with the closing cover of the overturning member and rotates reversely, because the second moving block 33 is abutted with the hovering output shaft 31 through the inclined surface, when the hovering output shaft 31 rotates synchronously with the closing cover of the overturning member and rotates reversely, the area of mutual abutment between the inclined surface of the second moving block 33 and the inclined surface of the hovering output shaft 31 is gradually reduced, so that the second moving block 33 is pushed to move gradually into the housing 1 and compress the second pressure spring 32, the second pressure spring 32 is compressed to generate a damping effect on the second moving block 33 and transmit and act on the hovering output shaft 31, and further the overturning member is prevented from closing the cover and storing energy. Therefore, the turnover piece can be stably closed; moreover, under the condition of no external force action when power circuit breaking faults including insufficient power or shutdown of the motor 21 occur, the damping action of the torsion spring 23 and the second compression spring 32 can balance the gravity borne by the turnover part, so that the turnover part can hover at any angle, and the danger of clamping injury caused by sudden cover closing of the turnover part due to no external force driving is avoided.

Moreover, the automatic turnover device of the embodiment is driven by the single power of the motor 21, so that the power output energy consumption of the device can be effectively reduced, the cost of the device is reduced, the noise generated when the device operates is reduced, and the turnover piece can be smoothly and stably opened and closed.

Example 2

The automatic turnover device of the present embodiment is the same as that of embodiment 1, except that, as shown in fig. 2, in the automatic turnover device of the present embodiment, the turnover mechanism 2 further includes a first pressure spring 27 and a first moving block 28; one end of the first pressure spring 27 is fixedly connected to the housing 1, and the other end is fixedly connected to the first moving block 28; the first moving block 28 abuts against the other end of the turning output shaft 24, which is opposite to the end extending out of the housing 1, and the first moving block 28 and the turning output shaft 24 are engaged and abutted through mutually matched curved surfaces.

When the turnover output shaft 24 rotates relative to the first moving block 28, the curved surface on the first moving block 28 and the mutually adaptive curved surface on the turnover output shaft 24 can be further adapted or mismatched, so that the first moving block 28 can move close to the turnover output shaft 24 under the stretching action of the first pressure spring 27, or can push away from the turnover output shaft 24 and compress the first pressure spring 27 under the mismatch action of the curved surface of the turnover output shaft 24.

Moreover, the rotating direction of the turnover output shaft 24 rotating and pushing the first moving block 28 to compress the first pressure spring 27 is the same as the rotating direction of the turnover output shaft 24 rotating to drive the turnover part to close the cover; the rotating direction of the turning output shaft 24 rotating and making the first pressure spring 27 extend to push the first moving block 28 to move is the same as the rotating direction of the turning output shaft 24 rotating to drive the turning part to open the cover.

In this embodiment, the surface of the first moving block 28 abutting against the reverse output shaft 24 is an inclined surface, the surface of the reverse output shaft 24 abutting against the first moving block 28 is an inclined surface adapted to the inclined surface of the first moving block 28, and the first moving block 28 and the reverse output shaft 24 abut against each other through the inclined surfaces adapted to each other.

The damping effect of the turnover mechanism 2 can be enhanced and ensured by the arrangement of the first pressure spring 27 and the first moving block 28. When the turnover part is turned over and the cover is closed, if the transmission action between the main shaft 22 and the turnover output shaft 24 is lost due to the fault of the speed change gear set 25, the damping action of the turnover output shaft 24 on the turnover part can be kept through the first pressure spring 27 and the first moving block 28, so that the damping action borne by the two ends of the turnover part is kept balanced, and the phenomenon that the turnover part causes the hovering mechanism 3 and the turnover part to be damaged due to the loss of balance is avoided.

The above embodiments are merely preferred embodiments of the present invention, and only lie in further detailed description of the technical solutions of the present invention, but the protection scope and the implementation manner of the present invention are not limited thereto, and any changes, combinations, deletions, replacements, or modifications that do not depart from the spirit and principles of the present invention will be included in the protection scope of the present invention.
