Specifically, the connecting assembly 13 may include a first flange 131, a second flange 132, a guide body 133, and a resilient element 134. The first flange 131 and the second flange 132 are connected through a guide 133, and the rotating shaft 121 of the rotating assembly 12 is used for driving the first flange 131 to rotate so as to drive the second flange 132 to rotate synchronously. The second flange 132 is disposed on the cover 21, and the elastic member 134 is disposed between the first end of the guide body 133 and the first flange 131. The first end of the guiding body 133 is an end of the guiding body 133 close to the rotating assembly 12, that is, the first end of the guiding body 133 is disposed close to the rotating assembly 12.

Alternatively, the guiding body 133 may be disposed in a column shape, that is, the guiding body 133 is a guiding column.

In fig. 2, the elastic element 134 is shown by a spring, but in some other embodiments, the elastic element 134 is not limited to this, for example, the elastic element 134 may also be an elastic sheet, an elastic rib, or the like.

As shown in fig. 3, the flange is a connecting member, and may have a disk shape, and a plurality of connecting holes H are formed in the disk, so that the flange can be connected to other components through the connecting holes H.

More specifically, the first flange 131 is provided with a first through hole S, the guide body 133 is movably disposed in the first through hole S up and down, the outer diameter of the first end of the guide body 133 is larger than the diameter of the first through hole S to limit the guide body 133, and the second end of the guide body 133 is fixed to the second flange 132. Alternatively, the second end of the guide post 133 may be movably disposed to the second flange 132. For example, a through hole or a blind hole may be provided in the second flange 132, and a sliding bearing may be provided in the hole, and the second end of the guiding stud 133 may be provided in the sliding bearing, so that the guiding stud 133 is movable relative to the second flange 132.

The linear bearing guide mechanism ensures that the first flange 131 and the second flange 132 move only in the same direction, thereby reducing the left-right shaking of the guide body 133.

In fig. 2, the guiding body 133 is limited by a nut, and in some other embodiments, the guiding body 133 may also include a head portion to limit the guiding body 133.

During the process of opening the cover 21, the elastic element 134 is compressed under the gravity of the second flange 132 and the cover 21, and a certain gap exists between the first flange 131 and the second flange 132, i.e. a buffer space of the second flange 132. In the process of closing the cover body 21, even if the cover body 21 is displaced upward by a small amount due to the pressurization in the tank opening airbag, due to the existence of the buffer space of the second flange 132, the second flange 132 can be displaced upward by a certain distance without causing the upward displacement of the entire connecting assembly 13, and thus, the damage of the automatic lid opening and closing apparatus 10 is not caused.

The embodiment at least has the following beneficial effects: in this embodiment, an elastic element 134 is disposed between one end of the guiding body 133 and the first flange 131, and a certain gap, i.e. a buffer space of the second flange 132, is formed between the first flange 131 and the second flange 132 due to the gravity of the cover 21 and the action of the elastic element 134 during the opening process of the cover 21. When the cover body 21 is closed, even if the cover body 21 is upwardly displaced a distance due to the pressurization of the airbag in the tank, the second flange 132 is only upwardly displaced a distance due to the presence of the buffer space, and the entire connecting assembly 13 is not upwardly displaced, so that the automatic lid opening and closing apparatus 10 is not damaged.

Referring to fig. 4 in conjunction with fig. 5, fig. 4 is a schematic structural diagram of a second embodiment of the automatic lid opening and closing apparatus 10 of the present application, and fig. 5 is an enlarged schematic view of a connecting assembly 13 of the second embodiment of the automatic lid opening and closing apparatus 10 of the present application.

And, the outer diameter of the adjusting nut 1331 is greater than the diameter of the first through hole S to prevent the guide body 133 from falling off from the first flange 131, so as to limit the guide body 133.

When the adjustment nut 1331 is rotated to compress the spring, the compression amount of the spring becomes large, and the gap between the first flange 131 and the second flange 132 formed by the weight of the cover body 21 and the second flange 132 when the cover is opened is reduced. When the adjustment nut 1331 is rotated to release the compression amount of the spring, the compression amount of the spring becomes small, and a gap between the first flange 131 and the second flange 132 formed by the weight of the cover body 21 and the second flange 132 when the cover is opened may increase. That is, the adjusting nut 1331 is rotated to change the gap between the first flange 131 and the second flange 132, so as to change the size of the buffer space of the second flange 132, and further adapt to different upward displacement of the cover body 21 during opening.

More specifically, a through hole is formed at a first end of the rocker 122, and a second end of the rotating shaft 121 is disposed in the through hole, so that the first end of the rocker 122 is fixedly connected with the second end of the rotating shaft 121. Wherein, the first end of rocker 122 can set up square through-hole, and the second end of axis of rotation 121 sets up to square head to realize the two complex fixed connection. Of course, in some other embodiments, the first end of the rocker 122 may be directly welded to the second end of the rotating shaft 121. The output shaft 1231 of the cylinder 123 is vertically disposed with respect to the rotation shaft 121, and in an operating state of the cylinder 123, the output shaft 1231 of the cylinder 123 makes a telescopic motion to rotate the rotation shaft 121.

Specifically, the rotating assembly 12 further includes a connecting member 126, a first end of the connecting member 126 is connected to the output shaft 1231, and a second end of the connecting member 126 is rotatably connected to the second end of the rocker 122.

The automatic lid opening and closing device 10 may include a control device (not shown), and the air cylinder 123 may control the movement of the output shaft 1231 of the air cylinder 123 through the control device, so as to automatically control the opening and closing of the lid 21. The driving assembly can also be other assemblies with driving functions, for example, a motor can rotate to drive a rotating shaft through a coupling.

Alternatively, in other embodiments, the automatic lid opening and closing device 10 may include a coupler, and the driving assembly drives the rotating shaft 121 to rotate by driving the coupler, so as to open and close the lid. The coupling is a device which connects two shafts or a shaft and a rotating part, rotates together in the process of transmitting motion and power and does not separate under normal conditions. In addition, through the arrangement of the coupler, the coupled machine member can be prevented from bearing excessive load, so that the function of overload protection can be achieved.

Referring to fig. 8 and 9, fig. 8 is a schematic view of the rotation shaft 121 of the rotation member 12 of the automatic lid opening and closing apparatus 10 according to the present application, and fig. 9 is a schematic view of the structure of the rotation shaft 121 of the rotation member 12 of the automatic lid opening and closing apparatus 10 according to the present application.

Specifically, the first end of the rotating shaft 121 passes through the second through hole of the third flange 135, and the third flange 135 is fixed to the first end of the rotating shaft 121 by the nut 128.

A cushion washer 129 is also provided between the third flange 135 and the nut 128. Because a large force exists between the third flange 135 and the rotating shaft 121 along the axial direction of the rotating shaft 121 in the process of opening and closing the cover, the washer 129 can play a certain buffering role, and the rotating shaft 121 or the third flange 135 is prevented from being loosened and even damaged by connection.

Specifically, the rotating assembly 12 further includes a tapered roller bearing L1 and a tapered roller bearing L2, the upper end 1213 of the shoulder 1212 of the rotating shaft 121 is provided with a first tapered roller bearing L1, and the lower end 1214 of the shoulder 1212 of the rotating shaft 121 is provided with a second tapered roller bearing L2, that is, the second tapered roller bearing L2 is disposed opposite to the first tapered roller bearing L1.

More specifically, referring to fig. 6, the first tapered roller bearing L1 is disposed in the first bearing housing L3, the second tapered roller bearing L2 is disposed in the second bearing housing L4, and both the first bearing housing L3 and the second bearing housing L4 are disposed in the rotating assembly bracket 125, so as to fix the first tapered roller bearing L1 and the second tapered roller bearing L2, and further fix the rotating shaft 121.

The tapered roller bearing is a radial thrust rolling bearing with a tapered roller as a rolling element, and belongs to a split bearing, and the inner ring and the outer ring of the bearing are both provided with tapered raceways, so that the rotating shaft 121 can rotate in the bearing. Also, the tapered roller bearing can withstand both radial and axial loads. This application uses two tapered roller bearings, and relative installation, can bear great axial force.

When the automatic lid opening and closing apparatus 10 performs automatic lid opening and closing, the rotary shaft 121 receives a force applied to the rotary shaft 121 by the weight of the lid 21 and the lifting of the lid 21, and thus the rotary shaft 121 receives a large force in the axial direction thereof. The first tapered roller bearing L1 and the second tapered roller bearing L2 can bear the large axial force, and the rotating shaft 121 can be firmly fixed to prevent the rotating shaft 121 from moving in the axial direction during rotation.

Specifically, referring to fig. 4, the bracket 11 includes a vertical beam 111 and a horizontal beam 112, which are vertically disposed, and one end of the vertical beam 111 is fixed to another structure, such as a workbench.

The first module 113 is provided with a second module 114, the second module 114 can move along the first guide rail, and the second module 114 is provided with a second guide rail along a second direction, which may be a vertical direction perpendicular to the first direction. The rotating element 12 is disposed on the second module 114, that is, the rotating element support frame 125 of the rotating element 12 is disposed on the second module 114, and the rotating element support frame 125 can move along the second guide rail.

Specifically, the bracket 11 of the present application may further include a driver (not shown), where the driver is connected to the controller and receives a control signal from the controller, and the driver enables the second module 113 to move along the horizontal direction on the first guide rail, and enables the rotating component support frame 125 to move along the vertical direction on the second guide rail, so that the rotating component 12 moves along the horizontal direction and the vertical direction.

When the rotating shaft 121 of the rotating assembly 12 rotates to open the cover 21, the driver may move the rotating assembly 12 vertically upward along the second guide rail so that the cover 21 is away from the opening in the vertical direction. And, the driver also causes the second module 114 to move horizontally along the first rail so that the lid body 21 is away from the can opening in the horizontal direction.

The embodiment has at least the following beneficial effects: in this embodiment, a spring is disposed between one end of the guiding body 133 and the first flange 131, and a certain gap, i.e., a buffer space of the second flange 132, exists between the first flange 131 and the second flange 132 due to the gravity of the cover 21 and the spring during the opening process of the cover 21. When the cover body 21 is closed, even if the cover body 21 is displaced upward by a distance due to pressurization of the airbag in the tank, the second flange 132 is displaced upward by only a distance due to the presence of the buffer space, and the entire connecting assembly 13 is not displaced upward, so that damage to the apparatus is not caused. Also, due to the adjusting nut 1331, the buffer space of the second flange 132 can be adjusted to accommodate different amounts of upward displacement of the cover 21. Further, the presence of the first tapered roller bearing L1 and the second tapered roller bearing L2 allows the rotary shaft 121 to receive a large axial force, and the rotary shaft 121 is stabilized. In addition, the output shaft of the driving assembly pushes the rocker 122 to rotate the rotating shaft 121, so that the cover 21 can be opened and closed by the extension and contraction of the output shaft, and the structure is simple and the automation degree is high. Further, the presence of the first module 113 and the second module 114 in the holder 11 enables the cover 21 to be moved during opening and closing of the cover 21, thereby preventing the cover 21 from obstructing the can 22 when the contents in the can 22 are manipulated.

The above embodiments are merely examples and are not intended to limit the scope of the present disclosure, and all modifications, equivalents, and flow charts using the contents of the specification and drawings of the present disclosure or those directly or indirectly applied to other related technical fields are intended to be included in the scope of the present disclosure.
