As a specific embodiment of the present invention, this embodiment discloses a cover-opening drive device 100, which is used to open a cover 210 of a target object 200. The target object 200 may also include a body 220 and a base 300. The body 220 is disposed on the base 300. The cover body 210 in the target object 200 is located above the body 220. The target object 200 of this embodiment may be a cavity structure, particularly a large cavity device. The cover opening drive device 100 of this embodiment may include a support mechanism 110 and a drive mechanism 120, wherein the support mechanism 110 may include a connecting portion 111 provided on the cover body 210 and a first hinge seat 112 provided on the main body 220, and the cover body 210 is rotatably connected to the main body 220 via the connecting portion 111 and the first hinge seat 112. The drive mechanism 120 is provided on one side of the target object 200 and is rotatably connected to the support mechanism 110. The bottom end of the drive mechanism 120 is rotatably connected to the base 300, and drives the cover body 210 to rotate relative to the main body 220 via the connecting portion 111. The top end of the drive mechanism 120 extends obliquely in a direction away from the connecting portion 111 and at a preset angle to the vertical direction, wherein the preset angle is 0-60°.

[0044] Specifically, the preset angle α in this embodiment can be 0°, 10°, 30°, 45° or 60°. The preset angle can be designed according to actual conditions.

[0045] Specifically, the cover-opening drive device 100 in this embodiment may include a support mechanism 110 and a drive mechanism 120, and the support mechanism 110 is arranged on one side of the cover body 210 and the main body 220, and has a connection portion 111 fixedly connected to the cover body 210, the bottom of the drive mechanism 120 is rotatably connected to the base 300, and the top is rotatably connected to the connection portion 111, so that the cover-opening drive device 100 and the target object 200 form an integral structure, thereby making the entire device more convenient for transportation, assembly and debugging, and more operable. In addition, the top of the drive mechanism 120 in this embodiment extends in a direction away from the connection portion 111 and at a preset angle to the vertical direction, so that the bottom of the drive mechanism 120 is closer to the target object 200, the bottom occupies a small area, and mainly utilizes the space above, thereby making the entire device occupy a small space, especially for large cavity covers, the advantage is more obvious, and the factory utilization rate is high.

[0046] As a specific embodiment of the present invention, the preset angle of this embodiment is 0-30 degrees. In this embodiment, the preset angle is limited to the range of 0-30 degrees. The smaller the preset angle value, the smaller the angle between the drive mechanism 120 and the vertical direction, which means that the occupied space is also smaller, and the utilization rate of the factory building can be improved.

[0047] As a specific embodiment of the present invention, the drive mechanism 120 of this embodiment may include a motor 121 and an electric cylinder 122, wherein the electric cylinder 122 is positioned at a predetermined angle relative to the vertical direction. The electric cylinder 122 may include a piston rod 1221 and a cylinder barrel 1222. The bottom end of the piston rod 1221 is rotatably connected to the base 300. The cylinder barrel 1222 is sleeved around the piston rod 1221 and moves relative to the piston rod 1221 under the drive of the motor 121. The cylinder barrel 1222 is rotatably connected to the connecting portion 111.

[0048] Specifically, the driving mechanism 120 of this embodiment may include a motor 121 and an electric cylinder 122. The electric cylinder 122 may include a piston rod 1221 and a cylinder 1222. The bottom of the piston rod 1221 is rotatably connected to the base 300, and the cylinder 1222 is sleeved outside the piston rod 1221. The cylinder 1222 is rotatably connected to the connecting part 111. The motor 121 drives the cylinder 1222 to move relative to the piston rod 1221, thereby driving the connecting part 111 and the cylinder cover to rotate relative to the main body 220.

[0049] As a specific embodiment of the present invention, the support mechanism 110 of this embodiment may include a first hinge seat 112 and a hinge leaf 113. The first hinge seat 112 is fixedly mounted on the body 220 and is provided with a first axial hole 1121. The hinge leaf 113 is fixedly mounted on the cover 210 and is provided with a third axial hole (not shown). A first pin 140 passes through the first axial hole 1121 and the third axial hole, allowing the cover 210 to rotate relative to the body 220 about the first pin 140.

[0050] As a specific embodiment of the present invention, a second hinge seat 221 is provided on the base 230 of this embodiment, and a second axial hole 222 is provided on the second hinge seat 221. A second pin 1223 is provided at the bottom end of the piston rod 1221. The second pin 1223 is correspondingly disposed in the second axial hole 222 to enable the electric cylinder 122 to rotate relative to the body 220 about the second pin 1223.

[0051] Specifically, in this embodiment, the second axial hole 222 and the second pin 1223 cooperate to enable the electric cylinder 122 to be rotatably connected relative to the body 220 and the base 300. Of course, the positions of the second axial hole 222 and the second pin 1223 can be interchanged, with the second pin 1223 positioned at the second hinge seat 221 and the second axial hole 222 positioned at the piston rod 1221. Regardless of the design location of the second axial hole 222, it can be a circular hole or a waist-shaped hole. A waist-shaped hole is preferred, as this allows for sufficient clearance between the electric cylinder 122 and the body 220 during relative rotation, preventing jamming.

[0052] As a specific embodiment of the present invention, the cover opening drive device 100 of this embodiment may further include a limiting mechanism 130, which is arranged on the side of the main body 220 having the support mechanism 110, so that when the cover body 210 is rotated to the maximum flipping angle of the main body 220, one side of the support mechanism 110 abuts against the limiting mechanism 130.

[0053] The limiting mechanism 130 in this embodiment can limit the cover body 210 when it rotates to the maximum flip angle relative to the main body 220, thereby preventing the cover body 210 from flipping too large and reducing the risk of the cover body 210 overturning due to the overall center of gravity shifting toward the electric cylinder 122 side.

[0054] As a specific embodiment of the present invention, the limiting mechanism 130 of this embodiment may include two limiting plates 131 extending toward the cover 210. The highest points of the limiting plates 131 are located above and below the height of the axis of rotation of the cover 210 relative to the main body 220. This allows the limiting plates 131 to mechanically limit the cover 210 and to position the cover 210 at approximately 90°±15° from the horizontal plane. This means that the maximum tilting angle of the cover 210 can be approximately 90°±15°, although the specific angle can be customized.

[0055] Figure 4 is an enlarged view of point I in Figure 1 . As a specific embodiment of the present invention, a sensor 132 is provided at the limit plate 131 of this embodiment. Sensor 132 is electrically connected to motor 121, such that when sensor 132 is triggered, motor 121 is turned off. Sensor 132 in this embodiment electrically controls the rotation of cover 210. When cover 210 rotates to the position that triggers sensor 132, motor 121 stops, causing cover 210 to also stop rotating. Motor 121 is located at the top of drive mechanism 120.

[0056] The limiting mechanism 130 in this embodiment may include a limiting plate 131 and a sensor 132 . The electric limiting and the mechanical limiting work together, greatly reducing the possibility of safety accidents caused by operator misoperation.

[0057] In addition, in order to avoid safety accidents during the opening process of the cover body 210, the self-locking characteristics are taken into consideration when selecting the motor 121 and the electric cylinder 122. If the device suddenly loses power during the opening process, the mechanical structure will not cause the cover body 210 to suddenly close due to the power outage, causing unnecessary safety accidents.

[0058] As a specific embodiment of the present invention, a fourth axial hole 1111 is provided at the connecting portion 111 of this embodiment, and a third pin shaft 1224 is provided outside the cylinder barrel 1222 of the electric cylinder 122. The third pin shaft 1224 is provided at the fourth axial hole 1111 so that the electric cylinder 122 can rotate relative to the connecting portion 111 with the third pin shaft 1224 as the rotating axis.

[0059] The positions of the fourth shaft hole 1111 and the third pin 1224 of this embodiment can be swapped, that is, the fourth shaft hole 1111 is set outside the cylinder barrel 1222 of the electric cylinder 122, and the third pin 1224 is set at the connecting portion 111. The specific design can be selected according to actual conditions.

[0060] As a specific embodiment of the present invention, this embodiment further provides a cavity device, which may include the above-mentioned lid opening drive device 100. The cavity device uses the lid opening drive device 100 to smoothly open the lid 210 of the cavity device, while reducing the floor space, improving the utilization rate of the factory, and avoiding the possibility of safety accidents caused by power failure, displacement of the center of gravity of the lid 210, or operator error during lid opening, thereby improving the safety of lid opening in the cavity device.
