Referring to fig. 1-3, a damping structure provided by an embodiment of the present application will now be described. The damping structure includes a housing 1, a shaft body 2, a limiting member 32 and an elastic member 31. The shaft body 2 is rotatably installed in the housing 1, one end of the shaft body 2 extends out of the housing 1, and the shaft body 2 is provided with a limiting portion 21. The stopper 32 is slidably mounted on the inner wall of the housing 1 in the axial direction of the shaft body 2, and one surface of the stopper 32 abuts against the stopper portion 21. One end of the elastic element 31 abuts against one surface of the limiting element 32 departing from the limiting part 21, the other end of the elastic element 31 is connected with the shaft body 2, and the elastic element 31 is used for elastically abutting against the limiting element 32 to form damping between the limiting element 32 and the limiting part 21.

The elastic member 31 is connected between the stopper 32 and the shaft body 2. Damping is formed between the stopper 32 and the stopper portion 21 by the elastic force of the elastic member 31. After the components of the electronic device are turned to the preset positions, when the electronic device is in an unstable environment or the components of the electronic device are subjected to external force, the external force applied to the components of the electronic device can be at least partially offset by the damping between the limiting part 32 and the limiting part 21, so that the components of the electronic device are not easy to rotate, and the stability of the components of the electronic device is improved.

In addition, after the components of the electronic device are turned over to any angle, damping can be formed between the limiting part 32 and the limiting part 21 of the shaft body 2, and then the limiting requirements of the components of the electronic device at different angles are met.

The position-limiting member 32 may be a block or a sheet structure, and is not limited herein. It can be understood that the housing 1 can limit the position of the position-limiting member 32, and when the shaft body 2 rotates relative to the housing 1, the position-limiting member 32 is not driven to rotate. Meanwhile, the limiting member 32 can move axially relative to the housing 1 along the shaft body 2, and therefore when the elastic force of the elastic member 31 is applied to the limiting member 32, the reliability of the abutment between the limiting member 32 and the limiting portion 21 can be ensured.

When the components of the electronic device are mounted on the shaft body 2, the housing 1 of the damping structure is fixed. For example, the electronic apparatus may be provided with a structure for fixing the housing 1, such as a bracket, and a component of the electronic apparatus is fixed to an end of the shaft body 2 protruding from the housing 1. When the shaft body 2 rotates relative to the shell 1, parts of the electronic equipment are driven to rotate synchronously with the shaft body 2, and therefore the parts of the electronic equipment are turned over.

When the shell 1 rotates reversely relative to the shaft body 2, the electronic equipment components on the shell 1 can be driven to rotate synchronously, and the electronic equipment components can be turned over.

Illustratively, the housing 1 includes a first casing 13 and a cover 15 covering an end portion of the first casing 13, the shaft body 2 is rotatably mounted in the first casing 13, and one end of the shaft body 2 extends from the cover 15. A bearing can be arranged between the cover body 15 and the shaft body 2, and the bearing can be a rotating bearing or a sliding bearing, and can support and limit the shaft body 2 through the bearing.

In a possible implementation, referring to fig. 2, 3 and 6, a snap spring can be used as the clamping member 6, and it can be understood that the snap spring is a sheet structure arranged in an arc shape. An annular groove 22 for the snap spring to extend into is formed in the outer peripheral surface of the shaft body 2, wherein the height of the annular groove 22 is matched with the thickness of the snap spring, and the snap spring can be fixed on the shaft body 2 after extending into the annular groove 22. The clamp spring is used for abutting against one end, away from the limiting part 32, of the elastic part 31. The aforesaid setting is convenient for install in the dismantlement of chucking spare 6, and simultaneously, the jump ring can play the effect of outrigger to elastic component 31.

In some embodiments, a nut may be used as the clamping member 6, and the outer circumferential surface of the shaft body 2 is provided with an external thread, and the nut is sleeved on the shaft body 2 and is in threaded connection with the shaft body 2.

In other embodiments, a stepped portion may be provided on the shaft body 2, a gap may be provided between the stepped portion and the limiting member 32, one end of the elastic member 31 abuts against the limiting member 32, and the other end abuts against the stepped portion, which is not limited herein.

In an embodiment, please refer to fig. 2 and fig. 3, as a specific implementation manner of the damping structure provided in the embodiment of the present application, the damping structure further includes a first washer 33 sleeved on the shaft body 2. One surface of the first gasket 33 abuts against one end of the elastic element 31, and the other surface of the first gasket 33 abuts against one surface of the limiting element 32 departing from the limiting part 21.

Alternatively, the first pad 33 and the second pad 34 may be provided at both ends of the elastic member 31, respectively, and one surface of the first pad 33 remote from the elastic member 31 may abut against the stopper 21, and one surface of the second pad 34 remote from the elastic member 31 may abut against the retainer 6.

In this embodiment, the number of the first spacers 33 and the number of the second spacers 34 are not limited, and the amount of compression of the elastic member 31 can be adjusted by adjusting the number of the first spacers 33 and the number of the second spacers 34, so as to adjust the pressure exerted on the limiting member 32 by the elastic member 31, and thus adjust the friction force between the limiting member 32 and the limiting portion 21, so as to adjust the amount of damping between the shaft body 2 and the housing 1.

In an embodiment, referring to fig. 7 and 8, as a specific implementation manner of the damping structure provided in the embodiment of the present application, a protrusion 321 is convexly disposed on an outer circumferential surface of the limiting member 32, a sliding slot 11 extending along an axial direction of the shaft body 2 is disposed on an inner wall of the housing 1, and the protrusion 321 extends into the sliding slot 11 and is slidably connected with the sliding slot 11.

The number of the sliding slots 11 is the same as that of the protrusions 321 on the limiting member 32, and the protrusions 321 are slidably disposed in the sliding slots 11 in a one-to-one correspondence manner.

In this embodiment, the limiting member 32 can be guided and limited by the matching of the sliding groove 11 and the protrusion 321, so that the limiting member 32 can only move relative to the housing 1 along the axial direction of the shaft body 2 and the limiting member 32 cannot rotate relative to the housing 1.

Further, one end of each sliding groove 11 facing the inside of the housing 1 is blocked, so that the sliding grooves 11 can limit the distance that the limiting member 32 extends into the housing 1, and the assembly of the limiting member 32 is facilitated.

In other embodiments, a slide rail extending in the axial direction of the shaft body 2 may be provided on the inner wall of the housing 1, and a slidable slider may be provided on the slide rail, and the limiting member 32 may be mounted on the slider, which is not limited herein.

In this embodiment, the grooves 322 on both sides of the limiting member 32 can be filled with lubricating oil, so as to prevent dry friction between the limiting member 32 and the limiting portion 21 and between the limiting member 32 and the elastic member 31, i.e., reduce the friction coefficient of the limiting member 32, and ensure the service life of the limiting member 32. It should be noted that, in order to ensure the friction force between the limiting member 32 and the limiting portion 21, the elastic force of the elastic member 31 needs to be increased correspondingly to ensure the damping between the limiting member 32 and the limiting portion 21.

The shape of the groove 322 on the limiting member 32 is not limited in this embodiment, for example, the groove 322 may form a concentric circle or a spiral shape on the limiting member 32. Preferably, the groove 322 is spirally disposed on the position-limiting member 32, which is beneficial to increasing the volume of the groove 322, so that more lubricant can be injected into the groove 322, and the service life of the position-limiting member 32 is further prolonged.

The embodiment of the application further provides a turnover driving mechanism, including driving medium 4, driving piece 5, main control board 7 and the damping structure that any of the above-mentioned embodiments provided, driving medium 4 is connected between driving piece 5 and shell 1, and the input of driving medium 4 is connected with the output of driving piece 5, and the output of driving medium 4 is connected with the one end that axis body 2 is located shell 1, and main control board 7 is installed on shell 1 and is connected with driving piece 5 electricity.

For example, a gear box can be used as the transmission member 4, i.e. the transmission component can be a gear set, the gear set can be a parallel shaft gear set or a planetary gear set, the gear set can be a single-stage transmission or a multi-stage transmission, and the invention is not limited thereto.

A motor may be used as the drive 5. In a possible implementation, the two ends of the housing 41 of the transmission member 4 are fixed to the body of the driving member 5 and the housing 1, respectively, so that the shaft body 2 can be driven to rotate relative to the housing 1 when the driving shaft of the driving member 5 rotates. Fig. 4 and 5 show that, the inside of the first casing 13 is provided with a limiting plate, a plurality of convex portions 12 are convexly provided on one surface of the limiting plate facing the housing 41, one end of the housing 41 extends into the first casing 13 and abuts against the limiting plate, and a plurality of limiting grooves 411 for the corresponding convex portions 12 to extend into are provided at one end of the housing 41 extending into the first casing 13. After the protrusions 12 are inserted into the corresponding retaining grooves 411, the housing 41 and the retaining plate may be locked together using bolts.

For example, the main control board 7 may be mounted on an outer circumferential surface of the first housing 13, and the second housing 14 covers the first housing 13 to cover the main control board 7 so as to ensure that the main control board 7 can operate reliably. Can be connected main control board 7 and driving piece 5 with the signal line to main control board 7 can control opening of driving piece 5 and stop, and main control board 7 can control the rotation direction of the relative shell 1 of axis body 2 through the rotation direction of the 5 drive shafts of control driving piece, thereby the upset direction of the part of the electronic equipment of control and upset actuating mechanism connection.

In addition, after the turnover driving mechanism turns over the component of the electronic equipment to the preset position, the damping formed between the limiting part 21 and the limiting part 32 of the shaft body 2 at least partially offsets the self weight of the component of the electronic equipment and the external force applied to the component of the electronic equipment, so that the self weight of the component of the electronic equipment and the external force applied to the component are prevented from being directly transmitted to the transmission component inside the transmission part 4, the service life of the transmission component is prolonged, and the service life of the transmission part 4 is prolonged. Meanwhile, when the transmission component of the transmission member 4 has a fit clearance, the damping between the limiting portion 21 and the limiting member 32 is also helpful to eliminate idle rotation of the transmission component caused by the fit clearance, and improve the stability of the electronic equipment component.

In an embodiment, referring to fig. 2 and fig. 3, as a specific implementation manner of the turnover driving mechanism provided in the embodiment of the present application, the elastic element 31 and the limiting element 32 are respectively sleeved on the shaft body 2, and the elastic element 31, the limiting element 32, the shaft body 2, the driving element 5 and the transmission element 4 are coaxially disposed.

The elastic member 31 may be a spring or a cylindrical structure made of an elastic material, and the limiting member 32 may be a sheet structure and a hole through which the shaft body 2 passes is formed in the sheet structure. It should be mentioned that, when the damping structure further includes the first gasket 33 and the second gasket 34, the first gasket 33, the second gasket 34, the elastic element 31, the limiting element 32, the shaft body 2, the driving element 5 and the transmission element 4 are coaxially disposed.

Through the above arrangement, the elastic member 31, the limiting member 32, the driving member 5 and the transmission member 4 do not occupy a large installation space in the radial direction of the shaft body 2, which is beneficial to reducing the size of the turnover driving mechanism, so that the application scenes of the turnover driving mechanism can be increased. Meanwhile, the arrangement of the turnover driving mechanism is convenient.

In other embodiments, the limiting member 32 and the elastic member 31 may also be disposed between the shaft body 2 and the housing 1, for example, the limiting member 32 may be slidably mounted on the inner wall of the housing 1 through a sliding rail slider, the elastic member 31 may be a rod-shaped structure made of an elastic material, the middle of the rod-shaped structure is fixed to the inner wall of the housing 1, two ends of the rod-shaped structure respectively abut against the fastening member 6 and the limiting member 32, and elastic force is applied to the limiting member 32 through elastic bending of the rod-shaped structure, so that the limiting member 32 and the limiting portion 21 reliably abut against each other.

In an embodiment, referring to fig. 2, fig. 3 and fig. 9, as a specific implementation manner of the tumble driving mechanism provided in the embodiment of the present application, the tumble driving mechanism further includes a first gear 81 installed on the shaft body 2, a second gear 82 rotatably installed on the housing 1 and engaged with the first gear 81, a magnet installed on the second gear 82, and a detection element disposed opposite to the magnet, and the detection element is electrically connected to the main control board 7.

The main control board 7 is electrically connected with the detection element, so that the main control board 7 can receive the angle information of the rotation of the shaft body 2 acquired by the detection element and can control the driving part 5 according to the information. For example, when the shaft body 2 drives the component of the electronic device to rotate to the set angle, the detection element transmits the angle information of the shaft body 2 to the main control board 7, and the main control board 7 controls the driving member 5 to stop working after receiving the angle information of the shaft body 2.

In another possible implementation, the screen is mounted on the housing 1 of the tumble drive mechanism, and the end of the shaft body 2 protruding from the housing 1 is fixed to the top of the automobile.

When the electronic device is a robot, the overturning driving mechanism can be used for driving the arm of the robot to move, the overturning driving mechanism is fixed on the body of the robot, and the arm of the robot is installed on the overturning driving mechanism. Wherein, the shell 1 of the turnover driving mechanism can be fixed with the body of the robot, and the arm of the robot is arranged at one end of the shaft body 2 extending out of the shell 1. Alternatively, the arm of the robot is attached to the end of the shaft 2 extending from the housing 1, and the housing 1 is fixed to the body of the robot.
