DETAILED DESCRIPTION OF THE EMBODIMENT

The present invention will be described in detail below with reference to 20 the accompanying drawings and embodiments.

Example 1

As shown in Fig. 1, a flipping device comprises a fixing body 1 and a flipping body 2. The flipping body 2 and the fixing body 1 are hinged by a hinge 3, and the flipping body 2 can achieve 180° round flip with respect to 25 the fixing body 1.

As shown in Fig. 1, a push rod device is further included. In the present embodiment, the push rod device adopts an electric push rod 4, and the

2019100593 03 Jun 2019 bottom end of the electric push rod 4 is hinged with the hinging point 18 of the fixing body, and the electric push rod 4 can rotate around the hinging point 18 of the fixing body 1.

As shown in Fig. 1, the telescopic rod 5 of the electric push rod 4 and the flipping body 2 are connected via a force point offset device. The structure of the force point offset device is shown in Fig. 2, which includes a pin shaft 8 and a clamping shaft 9 fixed to the flipping body 2. Furthermore, the deflecting body 6 is included. In the present embodiment, the deflecting body 6 adopts a deflecting plate structure, a curved limiting slot 7 is provided on 10 the plate surface of the deflecting plate, and the deflecting body 6 is connected to the flipping body 2 through the pin shaft 8. The deflecting body 6 is rotatable around the pin shaft 8. As shown in Fig. 2, one end of the deflecting body 6 is hinged with the top end of the telescopic rod 5, and the clamping shaft 9 on the flipping body 2 is located inside the limiting slot 7.

When the deflecting body 6 rotates around the pin shaft 8, the clamping shaft 9 can relatively slide cooperated with the limiting slot 7.

As shown in Fig. 1, when the fixing body 1 and the flipping body 2 are in the forward flip starting position, the electronic push rod 4 drives the deflecting body 6 to rotate around the pin shaft 8 under the action of the 20 electronic push rod’s own weight, until the clamping shaft 9 abuts against the end wall of the limiting slot 7, following the deflecting body is in a stable state. At this time, the pin shaft 8 is offset from the axis of the telescopic rod 17 and is offsetted in the forward flip direction with respect to the axis of the telescopic rod 17.

According to Fig. 1, it can be seen that when the telescopic rod 5 is extended, a tendency of the deflecting body 6 rotating around the pin shaft 8 can be produced, but the deflecting body 6 is restricted by the clamping shaft

2019100593 03 Jun 2019 and the limiting slot 7, thus the deflecting body 6 cannot rotate. At this time, the pin shaft 8 serves as the force point of the flipping body 2, and transmits the thrust of the telescopic rod 5 to the flipping body 2, and makes the flipping body 2 flip forward. Combiningwith Fig. 3, with the extension of the telescopic rod 5, since the clamping shaft 9 abuts against the end wall of the limiting slot 7, the rotation of the deflecting body 6 is restricted, and the deflecting body 6 is always in a stable state, thereby ensuring the force point of the flipping body 2, that is, the pin shaft 8 is always offset from the axis of the telescopic rod 17 and is offsetted to the forward flip direction with respect 10 to the axis of the telescopic rod 17. The flipping body 2 flips upward during the forward flipping of the flipping body 2, at the same time, the bottom end of the electric push rod 4 generates an upward flipping action around the hinging point 18 of the fixing body 1.

As shown in Fig. 4, when the electric push rod 4 is rotated to be perpendicular to the fixing body 1, the electric push rod 4 cannot automatically rotate around the hinging point of the fixed point 18, and the further extension of the telescopic rod 5 can no longer produce thrust to make the flipping body 2 flip. But at the same time, as can be seen from Fig. 4, the flipping body 2 has been offsetted in the forward flip direction with respect to 20 the axis 17 of the telescopic rod, that is, the flipping angle of the flipping body 2 has exceeded 90°, and at this time, the flipping body 2 has a tendency to fall downward around the hinge 3 under its own weight. Combining with Fig. 5, under the action of the tendency of the flipping body 2 falling downward, the pin shaft 8 applies pressure to the deflecting body 6 so that the 25 deflecting body 6 has a tendency to flip around the hinge 3 in synchronization with the flipping body 2, but the deflecting body 6 is subjected to the pinching of the telescopic rod 5, thus blocks the downward flipping motion of the

2019100593 03 Jun 2019 flipping body 2. When the telescopic rod 5 performs the retracting action, the flipping body 2 flips down under the action of its own weight and drives the bottom end of the electric push rod 4 to rotate synchronously around the hinging point 18 of the fixing body, while the deflecting body 6 is always in a 5 stable state until the flipping body is flipped 180° to a horizontal state. As can be seen from Fig. 5, during the flipping process of the remaining angle, since the deflecting body 6 is in a stable state, the force point of the flipping body 2, that is, the position at which the pin shaft 8 is located is always offset from the axis 17 of the telescopic rod 5 and is offsetted to the flip direction.

During design, the maximum stroke of the telescopic rod 5 of the electric push rod 4 should be greater than or equal to the stroke required when the electric push rod 4 flips to be perpendicular to the fixing body 1. If the telescopic rod 5 is in the maximum stroke when the electric push rod 4 flips to be perpendicular to the fixing body 1, the flipping angle of the flipping body 2 is greater than 90°, there is a retraction stroke for the telescopic rod of the electric push rod after the flipping body 2 flips by 180°. As shown in Fig. 6, when the flipping body completes the forward flip by 180°, there is a retracting stroke for the telescopic rod 5, and the pin shaft 8 is still offset from the axis 17 of the telescopic rod and is offsetted to the forward flip direction.

As shown in Figs. 7 and 8, when the telescopic rod 5 continues to retract, the deflecting body 6 is pulled to rotate around the pin shaft 8, and the clamping shaft 9 and the limiting slot 7 are relatively slid, and when the stroke of the telescopic rod 5 turns back to zero, the pin shaft 8 is located on the axis 17 of telescopic rod, and there is a certain gap between the clamping shaft 9 and the end wall of the limiting slot 7, and the clamping shaft 9 does not abut against the end wall of the limiting slot 7. When the stroke of the telescopic rod 5 is zero, after the pin shaft 8 is located on the axis 17 of the

2019100593 03 Jun 2019 telescopic rod, there is a certain gap between the clamping shaft 9 and the end wall of the limiting slot 7. The electric push rod 4 has a tendency to continue to rotate around the hinging point 18 of the fixing body under its own weight, such tendency will cause the deflecting body 6 to continue to rotate.

Combining with Fig. 9, the electric push rod 4 drives the deflecting body 6 to continue to rotate under the action of its own weight, until the clamping shaft 9 abuts against the end wall of the limiting slot 7 to stop the rotation of the deflecting body 6. At this time, The pin shaft 8 is offset from the axis 17 of the telescopic rod and is offsetted in the reverse flip direction with respect to 10 the axis 17 of the telescopic rod to form a starting position for the reverse flip.

Through the introduction on the foregoing forward flipping action, the reverse flipping action can be fully understood by those skilled in the art, including the formation process of the forward flip starting position, and the reverse flipping is not described in detail herein.

The former 90° and the latter 90° flips require the extension stroke of the telescopic rod 5 of the electric push rod to coincide with the retracting stroke during the 180° flipping process of the flipping body 2, so the hinging point 18 of the fixing body 1 is required to be preferably located in the same vertical plane with the hinge 3 of the flipping body 2 during installation. If the 20 hinging point 18 of the fixing body is offset from the hinge 3, the stroke of the electric push rod and the parameters of each characteristic component need to be calculated in detail to ensure the mutual cooperation can be made, which causes great troubles for manufacturing and installation.

In this embodiment, the limiting slot 7 adopts a through slot structure, and the limiting slot 7 can also adopt a non-through sinking slot structure to extend the end of the clamping shaft 9 into the sinking slot. Of course, in addition to such structures, a notch can be directly formed at the end of the

2019100593 03 Jun 2019 deflecting body, that is, a notch is formed at the end of the deflecting body, and the clamping shaft can be inserted into the notch.

In addition to the deflecting body with the deflecting plate structure provided by the embodiment, the deflecting body can also adopt other 5 varieties. As shown in Fig. 10, the deflecting body can also adopt a fork-shape structure, including a deflecting rod 10, and the bottom of the deflecting rod 10 is provided with a hinging hole 11 hinged with the telescopic rod, a pin hole 12 is disposed in the middle of the deflecting rod 10. The top end of the deflecting rod is provided with two fork levers 13, and a limiting slot 7 is 10 formed between the two fork levers 13. During installation, the top of the telescopic rod 5 is hinged through the hinging hole 11, and the pin shaft 8 passes through the pin hole 12. The clamping shaft 9 is located inside the limiting slot 7, and the clamping shaft 9 abuts against the fork lever 13 which can also achieve the offset of the force point. In the inspiration of such a 15 structure, the deflecting body with the deflecting plate structure provided in this embodiment can also directly provide a notch at the end of the deflecting body, and the clamping shaft can be disposed inside the notch.

In addition, the electric push rod can also be arranged in an inverted manner, that is, the end of the telescopic rod 5 is hinged with the force point 20 of the fixing body 1, and the bottom end of the electric push rod is hinged with the deflecting body 6.

In addition to the electric push rod provided by the present embodiment, the driving device can also adopt a driving device with a telescopic rod structure such as a hydraulic push rod and a pneumatic push rod.

The electric push rod and the force point offset device provided in this embodiment are installed on the side surfaces of the fixing body 1 and the flipping body 2, and they can also be symmetrically installed on both sides. If

2019100593 03 Jun 2019 the fixing body 1 has an internal cavity structure, the electric push rod can also be installed inside the fixing body, and the corresponding force point offset device changes accordingly, and is arranged according to the reasonable installation position of the flipping body.

Example 2

This embodiment further modifies the force point offset device.

As shown in Fig. 11, in the present embodiment, a pin shaft 8 and a limiting slot 7 are disposed on the flipping body 2. As shown in Fig. 12, the deflecting body 6 is provided with a clamping shaft 9, a hinging hole 11, and 10 a pin hole 12. As shown in Fig. 13, after assembly, the pin shaft 8 passes through the pin hole 12, and the clamping shaft 9 passes through the limiting slot 7 on the flipping body 2, and the bottom end of the deflecting body 6 is hinged to the top end of the telescopic rod through the hinging hole 11. It can also achieve the effect of the force point offset achieved in the embodiment 1, 15 and ensure that the flipping body performs 180° round-flipping.

In addition, as shown in Fig 11, for the convenience of installation, the fixing plate 14 can be fixed on the flipping body 2, and the pin shaft 8 and the limiting slot 7 can be disposed on the fixing plate 14. The fixing plate 14 can be arranged to flexibly adjust the corresponding position of the force point 20 offset device on the flipping body 2. If the electric push rod is installed inside the fixing body, the fixing plate 14 can be installed on the surface of the flipping body to realize the normal installation of the force point offset device.

In this embodiment, the shape of the limiting slot 7 can also be 25 modificated structures according to the structure provided in Embodiment 1, such as providing a notch at the edge of the fixing plate, and the clamping shaft 9 can be disposed inside the notch.
