Description

Technical Field

[0001] This utility model relates to the field of automation, and in particular to a flip-opening and closing constraint mechanism. Background Technology

[0002] The flip-top structure consists of a rotating component that is rotatably connected to a base via a torsion spring, and a connecting structure that allows the rotating component to be detachably locked to the base. When performing maintenance or adjustment on the internal components of the flip-top structure, it is often necessary to disassemble the connecting structure to open the flip-top structure, and after completing the operation, press the rotating component back onto the base to facilitate locking the rotating component in place by the connecting structure.

[0003] When using automated equipment to open and close a flip-top cover, after the connecting structure is disassembled, the rotating component springs open automatically under the action of a torsion spring. Due to inertia, the rotating component releases instantaneous energy impact on the torsion spring. When the overall size of the flip-top cover is small, the torsion spring's impact resistance is weak, making it prone to damage. Therefore, when using equipment to automatically open and close the flip-top cover, it is necessary to configure the rotation of the rotating component to be controllable. Utility Model Content

[0004] The purpose of this invention is to provide a flipping opening and closing constraint mechanism for making the rotation of rotating parts controllable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A flip-opening and closing constraint mechanism, comprising: A clamping assembly includes an abutment member that is controllably movable along the x-axis and z-axis to abut a rotating member away from the base. The rotating member is rotatably connected to the base by a torsion spring and rotates about a rotation axis extending along the y-axis. The x-axis, the y-axis, and the z-axis are mutually perpendicular. The straightening assembly includes two clamping plates arranged opposite each other along the y-axis. The two clamping plates move synchronously and controllably along the x-axis and the z-axis, and move closer or further apart from each other controllably along the y-axis, for clamping the rotating component.

[0006] Optionally, the abutment includes an axle extending along the y-axis and a roller that rotates freely about the axle.

[0007] Optionally, the straightening assembly further includes a pushing member extending along the y-axis direction. The pushing member is connected to either of the clamping plates and is disposed on the side of the clamping plate near the base. When both clamping plates abut against the rotating member, the abutting member abuts against the side of the rotating member near the base.

[0008] Optionally, the straightening assembly includes two opposing pushing members, and the clamping assembly includes two opposing abutting members, the two abutting members moving synchronously and controllably along the x-axis and the z-axis.

[0009] Optionally, the rotating member includes an upper protrusion, a middle layer, and a lower protrusion. The upper protrusion is connected to the surface of the middle layer away from the base, and the lower protrusion is connected to the surface of the middle layer near the base. The edge of the middle layer is sleeved on the outside of the edges of the upper and lower protrusions. The abutting member is used to abut against the middle layer and is separated from the upper protrusion, and the pushing member is used to abut against the middle layer and is separated from the lower protrusion.

[0010] Optionally, a pressure cap is provided on the side of the rotating member away from the base. The pressure cap is rotatably connected to the base via another torsion spring and rotates about an opening and closing shaft extending along the y-axis. The opening and closing shaft is located on the side of the rotating shaft away from the rotating member. When the rotating member abuts against the base, it is detachably connected to the base. The abutting member is also used to abut against the side of the pressure cap away from the base, and the abutting member can be controllably moved relative to the pushing member along the z-axis.

[0011] Optionally, the flipping opening and closing constraint mechanism further includes a transfer module, a support frame, and a first driving member. The support frame is connected to the transfer module and can move controllably along the x-axis and the z-axis under the drive of the transfer module. The first driving member is connected between the guide component and the support frame and is used to drive the guide component to move controllably relative to the support frame along the z-axis.

[0012] Optionally, the straightening assembly further includes a straightening arm and a third driving member. The two third driving members arranged along the y-axis are controllably telescopic along the y-axis, and the end of the third driving member away from the other third driving member is connected to the support frame. The two straightening arms are respectively connected to the end of the third driving member close to the other third driving member, and the straightening arms extend in the direction close to the rotating member. The two clamping plates are respectively connected to the straightening arms.

[0013] The beneficial effects of this invention are as follows: A controllably movable contacting member abuts against the side of the rotating member away from the base, in conjunction with a torsion spring, causes the rotating member to rotate at a controllable speed in the direction approaching or moving away from the base. Two clamping plates hold the rotating member, preventing lateral deviation during rotation, helping to protect the corresponding torsion spring, and aiding in the positioning of the rotating member.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0020] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] This utility model application protects a flip-opening and closing constraint mechanism 2, including a clamping assembly 6 and a straightening assembly 7. The clamping assembly 6 includes an abutment member 63, which is controllably movable along the x-axis and z-axis to abut the side of the rotating member 12 away from the base 11. The rotating member 12 is rotatably connected to the base 11 by a torsion spring and rotates about a rotation axis extending along the y-axis. The x-axis, y-axis, and z-axis are mutually perpendicular. The straightening assembly 7 includes two clamping plates 73 arranged opposite each other along the y-axis. The two clamping plates 73 are controllably movable synchronously along the x-axis and z-axis, and controllably move closer or further apart along the y-axis to clamp the rotating member 12.

[0022] The controllably movable abutment member 63 abuts against the side of the rotating member 12 away from the base 11, and in conjunction with the torsion spring, causes the rotating member 12 to rotate at a controllable speed toward or away from the base 11. The rotating member 12 is clamped by two clamping plates 73 to prevent the rotating member 12 from deflecting laterally during rotation, which helps protect the torsion spring corresponding to the rotating member 12 and also helps in the positioning of the rotating member 12.

[0023] Please refer to the following examples for details.

[0024] Example: Please see Figure 2 The flip-opening and closing constraint mechanism 2 shown in a preferred embodiment of this application is used to control the flipping of the flip structure 1.

[0025] Please see Figure 1The flip-top structure 1 includes a base 11, a rotating component 12, and a pressure cap 13. The base 11 is horizontally positioned and includes a rectangular latching portion 111. Studs 112 and an opening / closing shaft 113 are connected to both sides of the latching portion 111 along the x-axis. The cylindrical studs 112 are connected to the surface of the base 11 and are parallel to the z-axis, while the opening / closing shaft 113 is parallel to the y-axis. A rotating shaft parallel to the y-axis connects the latching portion 111 and the opening / closing shaft 113. In this embodiment, the x-axis, y-axis, and z-axis are mutually perpendicular, with the z-axis extending vertically. The rectangular rotating component 12 is rotatably connected to the rotating shaft via a torsion spring. The rotating component 12 is assembled from a detachably connected insert plate 121 and a mating plate 123. The insert plate 121 includes two opposing and parallel slots 122. Two slots 122 are connected at both ends to form a rectangular frame structure. The side and end openings of slot 122 near the other slot 122 allow the mating plate 123, which is structurally compatible with the insert plate 121, to be inserted. The mating plate 123 includes an upper protrusion 124, an insertion portion 125, a lower protrusion 126, and a handle portion 127, which are stacked and connected in sequence. The upper protrusion 124, insertion portion 125, and lower protrusion 126 are all rectangular. The thickness of the insertion portion 125 matches the slot 122, and the upper protrusion 124 and lower protrusion 126 are respectively connected to the middle of two opposing surfaces of the insertion portion 125, resulting in a smaller thickness at the edges of the mating plate 123. The handle portion 127 is connected to one end of the insertion portion 125, and a through hole 128 for mating with a stud 112 is formed on the handle portion 127. When the mating plate 123 is inserted into the insert plate 121, the lower protrusion 126 of the mating plate 123 is brought close to the base 11, and the handle 127 of the mating plate 123 is moved away from the rotation axis. At least part of the edge of the insert 125 is embedded in the slot 122, and the insert plate 121 does not contact the upper protrusion 124 and the lower protrusion 126 during insertion. After the insert plate 121 and the mating part are fitted together to form the rotating member 12, the slot 122 and the insert 125 together form the middle layer, and the overall thickness of the middle layer is small, with the upper protrusion 124 and the lower protrusion 126 in a raised state. The pressure cap 13 is rotatably connected to the opening and closing shaft 113 via a torsion spring. The surface of the pressure cap 13 has a hollow portion 131 that mates with the upper protrusion 124 of the mating plate 123, and a threaded hole 132 that mates with the stud 112. When the rotating member 12 abuts against the base 11 and the pressure cap 13 presses against the rotating member 12, the lower protrusion 126 is embedded in the snap-fit ​​portion 111 and rubs against it, and is sleeved on the stud 112 through the hole 128. The hollow portion 131 is sleeved on the upper protrusion 124 and rubs against it. The threaded hole 132 abuts against the stud 112 and is detachably connected to the stud 112 via a locking screw 133. In this embodiment, the mating plate 123 is a CPU. The area enclosed by the snap-fit ​​portion 111 of the base 11 and the surface of the lower protrusion 126 form mutually mating pins, enabling electrical connection between the base 11 and the CPU.

[0026] When inserting, removing, or testing the mating plate 123, the locking screw 133 needs to be removed to allow the pressure plate 13 and the rotating component 12 to rotate and spring open in sequence, and the rotating component 12 to rotate to a preset angle and then be positioned. After completing the operation, the rotating component 12 and the pressure plate 13 need to be pushed to rotate to their initial positions in sequence, and the locking screw 133 needs to be installed.

[0027] Please see Figure 2 In this embodiment, the rotation of the pressure cap 13 and the rotating member 12 is controlled by the flip-opening and closing constraint mechanism 2.

[0028] The flip-opening and closing constraint mechanism 2 includes a transfer module 3, a support frame 4, a first driving component 5, a clamping component 6, and a straightening component 7, which are located on the side of the constraint axis away from the stud 112.

[0029] The transfer module 3 in this embodiment is a conventional dual-axis transfer module 3, including a transverse component 31 and a longitudinal component 32 connected to the transverse component 31. The transverse component 31 is used to drive the support frame 4 to move controllably along the x-axis, and the longitudinal component 32 is used to drive the support frame 4 to move controllably along the z-axis. The support frame 4 is flat and parallel to the y-axis, including a support portion 41 and a connecting portion 42. The support portion 41 is rectangular in shape and extends along the y-axis. The two support portions 41 are separated from each other and arranged along the y-axis. The connecting portion 42 is fixedly connected to the transfer module 3, disposed above the two support portions 41, and fixedly connected to the two support portions 41. Two first driving members 5 are both arranged along the z-axis and are respectively connected to the sides of the two support portions 41 away from the flip structure 1. The first driving members 5 can extend and retract controllably along the z-axis.

[0030] The clamping assembly 6 includes a second driving member 61, a clamping arm 62, and an abutment member 63. Two second driving members 61, extending along the y-axis and controllably telescopic, are respectively connected to the sides of two support portions 41 near the flip structure 1. The two second driving members 61 are flush, with one end of a second driving member 61 away from the other connected to the support portion 41, and the two clamping arms 62 are respectively connected to the ends of the second driving members 61 near the other. The vertical plane of the elongated, plate-like clamping arm 62 is parallel to the x-axis. One end of the clamping arm 62 is connected to the second driving member 61 and extends towards the flip structure 1, with the end of the clamping arm 62 near the flip structure 1 having a lower height. The end of the clamping arm 62 near the flip structure 1 is connected to the abutment member 63. The abutment member 63 includes a wheel axle 631 extending along the y-axis and a roller 632 rotatably connected to the wheel axle 631. The roller 632 is located on the side of the clamping arm 62 near the other clamping arm 62, and the end of the roller 632 near the flip cover structure 1 is located on the side of the clamping arm 62 near the flip cover structure 1.

[0031] The straightening assembly 7 includes a third drive member 71, a straightening arm 72, a clamping plate 73, and a pushing member 74. Two third drive members 71, extending along the y-axis and controllably telescopic, are respectively connected to the bottoms of two first drive members 5. When the first drive members 5 are compressed, the third drive members 71 move vertically upward. The end of the third drive member 71 away from the other third drive member 71 is connected to the first drive member 5, and the two straightening arms 72 are respectively connected to the ends of the third drive members 71 near the other third drive member 71. One end of the straightening arm 72 is connected to the third drive member 71 and extends towards the flip structure 1. The end of the straightening arm 72 near the flip structure 1 is lower in height, and the angle of inclination of the straightening arm 72 relative to the x-axis is smaller than that of the clamping arm 62. A cylindrical pushing member 74 is connected to the end of the straightening arm 72 near the flip structure 1, and the pushing member 74 is connected to the side of the straightening arm 72 near the other straightening arm 72. The clamping plate 73 is flat and parallel to the y-axis and the positioning direction. The clamping plate 73 is connected to the side of the guide arm 72 near another guide arm 72, adjacent to the pusher 74, and arranged parallel to the guide arm 72, and positioned on the side of the pusher 74 near the support frame 4. The side of the clamping plate 73 away from the guide arm 72 is perpendicular to the y-axis. The width of the pusher 74 along the y-axis is greater than that of the clamping plate 73, and the difference in width between the pusher 74 and the clamping plate 73 along the y-axis matches the rotating member 12.

[0032] In this embodiment, the first driving component 5, the second driving component 61, and the third driving component 71 are all cylinders.

[0033] When the locking bolt is removed, the first drive member 5 retracts, causing the height of the pusher 74 to be higher than that of the roller 632. The roller 632, under the action of the transverse and longitudinal modules, abuts against the surface of the pressure cap 13 away from the base 11. The two rollers 632 abut against both sides of the hollow portion 131 and are both away from the upper protrusion 124. When the locking screw 133 separates from the stud 112, the two rollers 632 move synchronously along the x-axis and z-axis in a direction away from the base 11. The pressure cap 13 rotates in the direction away from the base 11 under the action of the corresponding torsion spring until the corresponding torsion spring no longer applies a pushing force to the pressure cap 13.

[0034] When other mechanisms push the rotating member 12 upward away from the end of the torsion spring, causing the rotating member 12 to rotate, the two rollers 632 separate from each other along the z-axis under the action of the second drive member 61. Under the action of the transverse assembly 31 and the longitudinal assembly 32, they move upward, passing around the flip cover from both sides, bringing the two rollers 632 closer together. At the same time, the first drive member 5 extends to its longest length, so that the clamping plate 73 is located below and adjacent to the rollers 632. When the rotating member 12 rotates until the through hole 128 is away from the stud 112 and the lower protrusion 126 is away from the snap-fit ​​part 111, the transverse assembly 31 and the longitudinal assembly 32 drive the pressing assembly 6 and the straightening assembly 7 to move synchronously and controllably along the x-axis and z-axis. At this time, the first drive member 5 does not extend or retract. Through the movement, the rollers 632 abut against the middle layer and separate from the upper protrusion 124. At this time, the two clamping plates 73 approach each other under the action of the third driving member 71, until the clamping plates 73 clamp the middle layer. At this time, the pushing member 74 abuts against the side of the middle layer near the base 11, and the pushing member 74 is separated from the lower protrusion 126 without interference. When the rotating member 12 rotates to a preset angle, the clamping arm 62 and the guide arm 72 temporarily stop moving, so that the rotating member 12 is positioned. At this time, the rotating member 12 is parallel to the positioning direction.

[0035] The rotating component 12 is abutted from four directions by rollers 632, clamping plates 73, and pushing members 74, ensuring high positioning accuracy. After disassembly and installation of the positioned rotating component 12, the clamping assembly 6 and the straightening assembly 7 drive the rotating component 12 to rotate towards the base 11. When the gap between the rotating component 12 and the base 11 is small, the straightening arm 72 drives the clamping plates 73 and pushing members 74 away from the rotating component 12 along the y-axis, and the clamping assembly 6 continues to push the rotating component 12 until it is pressed firmly against the base 11.

[0036] Two rollers 632 separate along the y-axis and move under the drive of the transfer module 3, thereby reaching the position of the cover 13 in the open state. The cover 13 is clamped from four directions by the rollers 632, clamping plate 73, and pusher 74, and the cover 13 is pressed against the rotating member 12. The threaded hole 132 and the stud 112 are reconnected with the locking screw 133.

[0037] The flip-opening and closing constraint mechanism 2 in this embodiment constrains the rotation of the rotating component 12 and the pressure cap 13, which helps reduce damage to the torsion spring, extend its service life, and accurately positions the rotating component 12 for easy operation. When re-pressing the rotating component 12 and the pressure cap 13, the tight constraint prevents lateral deviation or misalignment during rotation, facilitating high-precision assembly of the flip-top structure 1. In this embodiment, the first driving component 5 and the transfer module including the longitudinal component 32 are combined, allowing the flip-opening and closing constraint mechanism 2 to switch between two modes: unidirectional contact with the contact component 63 and multi-directional constraint using the roller 632, clamp 73, and pusher 74 simultaneously. This improves the applicability of the flip-opening and closing constraint mechanism 2 and facilitates adjustments to the operating procedures for different flip-top structures 1. Furthermore, this embodiment integrates multiple functions into a single mechanism, improving space utilization.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
