DETAILED DESCRIPTION

[0028] The following is combined with Figures 1 to 11 This application is described in further detail.

[0029] Embodiment 1: The present application discloses a parallel movement mechanism with labor-saving opening and closing.

[0030] Reference Figure 1-8The parallel movement mechanism with labor-saving opening and closing includes a cabinet module 1, a translation module 2 and a synchronization module 3, wherein the cabinet module 1 includes a cabinet body 11 and a cabinet door 12, the cabinet body 11 is set with a front opening, and the cabinet door 12 covers the opening on the front side of the cabinet body 11; the translation module 2 is configured with two groups, and the two groups of translation modules 2 are respectively located on both sides of the cabinet module 1, and the translation module 2 specifically includes a support mechanism 21, an installation mechanism 22, a support connecting rod 23 and a stabilizing connecting rod 24, the support mechanism 21 is fixedly arranged on the top of the cabinet body 11 by an embedded fixing method, the installation mechanism 22 is fixedly arranged on the bottom of the cabinet door 12 by a bolt fixing method, and one end of the support connecting rod 23 is connected to the support The output end of the mechanism 21, the other end of the support link 23 is connected to the bottom of the mounting mechanism 22, one end of the stabilizing link 24 is connected to the stabilizing end of the support mechanism 21, and the other end of the stabilizing link 24 is connected to the top of the mounting mechanism 22, and a parallelogram structure is always formed between the support mechanism 21, the mounting mechanism 22, the support link 23 and the stabilizing link 24, so that the cabinet door 12 always remains parallel to the cabinet body 11 during the upward flipping and opening process; a synchronization module 3 is configured with a group, and the synchronization module 3 is connected between the stabilizing links 24 of the two groups of translation modules 2, so that the two groups of translation modules 2 in a parallelogram structure can move synchronously, thereby improving the stability of the cabinet door 12 during the upward flipping and opening process.

[0031] For storage cabinets with a higher height, the cabinet body 11 and the cabinet door 12 are connected and installed through the translation module 2, so that the cabinet door 12 covers the opening on the front side of the cabinet body 11; during the upward flipping and opening process of the cabinet door 12, since the cabinet door 12 is restricted by the translation module 2 (a parallelogram structure is always formed between the supporting mechanism 21, the installation mechanism 22, the supporting connecting rod 23 and the stabilizing connecting rod 24), the actual moving path of the cabinet door 12 during the upward flipping and opening process is close to a circular motion around the supporting mechanism 21, so that the distance between the cabinet door 12 and the cabinet body 11 during the upward flipping and opening process is relatively small, that is, the space occupied by the cabinet door 12 during the upward flipping and opening process is small, thereby improving the convenience of opening the cabinet door 12 and facilitating the installation and application of the storage cabinet in a limited space.

[0032] In the above, the support mechanism 21 is fixedly arranged on the top of the cabinet body 11 by means of embedded fixing, which is specifically manifested as follows in this embodiment: A mounting groove 13 is provided on the top of the cabinet body 11 to be embedded and matched with the support mechanism 21. The inner contour of the mounting groove 13 is matched with the outer contour of the support mechanism 21, and the outer wall of the support mechanism 21 is flush with the inner wall of the cabinet body 11 by adjusting the design depth of the mounting groove 13, thereby reducing the space occupied by the translation module 2 inside the cabinet module 1; on this basis, the support mechanism 21 is provided with a locking mechanism 25 that is snap-fitted with the mounting groove 13, and the locking mechanism 25 specifically includes a rotating member 251 and a snap-fitting member 252. The rotating member 251 is a hollow cylindrical structure, and the rotating member 251 is rotatably arranged on the support mechanism 21. The snap-fitting member 252 is a cam structure, and the snap-fitting member 252 is fixedly arranged on the outer periphery of the rotating member 251, and the support mechanism 21 is provided with a snap-fitting member 251. The card connector 252 is embedded in the matching condensation groove, so that the card connector 252 can rotate with the rotating member 251 to be exposed around the supporting mechanism 21, or the card connector 252 can be condensed inside the supporting mechanism 21 with the rotating member 251; when the supporting mechanism 21 is embedded in the mounting groove 13, the rotating member 251 is rotated by a tool to drive the card connector 252 to rotate to be exposed around the supporting mechanism 21, so that the card connector 252 is embedded in the inner wall of the mounting groove 13 to form a clamping effect, thereby achieving the support mechanism 21 to remain stably placed inside the mounting groove 13. If the cabinet body 11 is made of hard metal material, it is necessary to set a clamping groove that is compatible with the card connector 252 on the inner wall of the mounting groove 13 to achieve the support mechanism 21 to remain stably placed inside the mounting groove 13.

[0033] In the above, the support mechanism 21 can form a supporting effect on the cabinet door 12 through the support link 23, so that the cabinet door 12 can be supported when it is flipped up and opened to a predetermined angle, so as to prevent the cabinet door 12 from shaking and restoring to a closed state by its own gravity, so that the cabinet door 12 can remain in an open state. In this embodiment, it is specifically manifested as follows: The support mechanism 21 specifically includes a mounting component 211, a sliding component 212, an eccentric component 213 and a reset component 214; wherein, the outer contour of the mounting component 211 is adapted to the inner contour of the mounting groove 13, that is, the mounting component 211 is embedded in the mounting groove 13, and the locking mechanism 25 is arranged on the mounting component 211, that is, the locking mechanism 25 enables the mounting component 211 to be stably placed inside the mounting groove 13; the sliding component 212 is a metal plate structure, and the sliding component 212 is slidably arranged in a guide rail preset inside the mounting component 211, so that the sliding component 212 can slide along the length direction of the mounting component 211, and in addition, the sliding component 212 is penetrated by a sliding hole 4, one side of the sliding hole 4 is an asymmetric arc inner wall, and the other side is a rectangular inner wall; the eccentric component 213 is an eccentric wheel structure, and the eccentric component 213 is penetrated by the sliding hole 4, and The eccentric component 213 is rotatably arranged on the mounting component 211. The eccentric component 213 can contact the arc-shaped inner wall portion of the sliding hole 4 during the rotation process. The raised edge of the eccentric component 213 is used to push the sliding component 212 to slide forward along the length direction of the mounting component 211. The rotation axis of the eccentric component 213 also passes through the outer wall of the mounting component 211 to provide an installation basis for the support link 23, that is, one end of the support link 23 is fixedly arranged on the eccentric component 213; the reset component 214 is arranged between the mounting component 211 and the sliding component 212, and is used to pull the sliding component 212 to slide backward along the length direction of the mounting component 211, and the direction in which the reset component 214 drives the sliding component 212 to slide is opposite to the direction in which the eccentric component 213 drives the sliding component 212 to slide, so that the eccentric component 213 maintains sliding contact with the sliding hole 4. The side of the sliding hole 4 that is in sliding contact with the eccentric component 213 is set as an asymmetric arc-shaped inner wall, that is, the side of the sliding hole 4 away from the reset component 214 is defined as the sliding inner wall 41, and the eccentric component 213 actually maintains sliding contact with the sliding inner wall 41. The sliding inner wall 41 of the sliding hole 4 specifically includes an upward sliding segment 411 and a closed sliding segment 412. The upward sliding segment 411 and the closed sliding segment 412 are smoothly connected. The connection point between the upward sliding segment 411 and the closed sliding segment 412 is the reversing point 413, and when the eccentric component 213 slides to the reversing point 413, the sliding component 21 2 force balance; that is, after the eccentric component 213 slides over the reversing point 413, the sliding component 212 is pulled by the reset component 214, and the sliding component 212 continues to slide along the length direction of the mounting component 211 until the eccentric component 213 continues to rotate until the raised edge of the eccentric component 213 is located at the end of the upward sliding section 411 / the closed sliding section 412, the upward sliding section 411 corresponds to the open state of the cabinet module 1, and the cabinet door 12 remains stably open at this position, and the closed sliding section 412 corresponds to the closed state of the cabinet module 1, and the cabinet door 12 remains stably closed at this position.

[0034] The specific structure of the support mechanism 21 can also refer to the embedded furniture support system with publication number CN118087986A proposed by the applicant in 2024, which will not be repeated here; when the cabinet door 12 is flipped up and opened to a predetermined angle, the support mechanism 21 forms a supporting effect on the cabinet door 12 through the support link 23 to prevent the cabinet door 12 from shaking and restoring to a closed state under the action of its own gravity, so that the cabinet door 12 remains in an open state, which can achieve a labor-saving effect.

[0035] In this embodiment, in order to lift the cabinet door 12, it is flipped upward and opened to the maximum extent.

[0036] In a first aspect, the planes where the support link 23 and the stabilizing link 24 are located are staggered with each other. Specifically, the support link 23 and the stabilizing link 24 can be staggered with each other by extending the length of the stabilizing end of the support mechanism 21 .

[0037] Secondly, an avoidance position 241 is provided at one end of the stabilizing link 24 close to the mounting mechanism 22 . Specifically, the arc-shaped avoidance position 241 can be formed by setting one end of the stabilizing link 24 close to the mounting mechanism 22 into an arc-shaped structure.

[0038] When the cabinet door 12 is flipped up and opened to nearly the maximum limit, since the planes where the support link 23 and the stabilizing link 24 are located are staggered with each other, and since the stabilizing link 24 avoids the top edge of the cabinet body 11, the above two points enable the cabinet door 12 to have the conditions to continue to flip up and open until the cabinet door 12 is flipped up and opened to the maximum limit. At this time, the top edge of the cabinet body 11 is embedded in the avoidance position 241, and the support link 23 and the stabilizing link 24 are partially overlapped.

[0039] In the above, the synchronization module 3 can keep two groups of translation modules 2 in synchronous motion to improve the stability of the cabinet door 12 during the upward opening process, which is specifically manifested as follows in this embodiment: The synchronization module 3 specifically includes a synchronization rod 31 and two groups of connecting parts 32. The two groups of connecting parts 32 are respectively fixedly arranged at one end of the two groups of stabilizing links 24 close to the mounting mechanism 22. The connecting parts 32 and the stabilizing links 24 are fixed by screws. The two groups of connecting parts 32 are provided with connecting grooves 33 on the side close to each other. The connecting grooves 33 are square groove structures. The synchronization rod 31 is a metal round tube structure. The synchronization rod 31 is a fixed length. Both ends of the synchronization rod 31 are arranged to be rectangular structures adapted to the connecting grooves 33, so that the two ends of the synchronization rod 31 are respectively embedded in the two groups of connecting grooves 33. During the upward flipping and opening process of the cabinet door 12, the two groups of stabilizing links 24 rotate synchronously with the help of the synchronization module 3, so that the two groups of parallelogram-shaped translation modules 2 can move synchronously, thereby improving the stability of the cabinet door 12 during the upward flipping and opening process.

[0040] Implementation principle: For a storage cabinet with a relatively high height, the cabinet body 11 and the cabinet door 12 are connected and installed through the translation module 2, so that the cabinet door 12 covers the opening on the front side of the cabinet body 11; during the upward flipping and opening process of the cabinet door 12, since the cabinet door 12 is restricted by the translation module 2 (the supporting mechanism 21, the installation mechanism 22, the supporting connecting rod 23 and the stabilizing connecting rod 24 always form a parallelogram structure), the actual moving path of the cabinet door 12 during the upward flipping and opening process is close to a circular motion around the supporting mechanism 21, so that the distance between the cabinet door 12 and the cabinet body 11 during the upward flipping and opening process is relatively small, that is, the space occupied by the cabinet door 12 during the upward flipping and opening process is small, thereby The convenience of opening the improved cabinet door 12 is convenient for installation and application of the storage cabinet in a limited space; and in the process of the cabinet door 12 being flipped up and opened, the two groups of stabilizing links 24 rotate synchronously with the help of the synchronization module 3, so that the two groups of translation modules 2 with a parallelogram structure can move synchronously, thereby achieving the stability of the improved cabinet door 12 in the process of being flipped up and opened; in addition, when the cabinet door 12 is flipped up and opened to a near maximum limit, since the planes where the supporting links 23 and the stabilizing links 24 are located are staggered with each other, and since the stabilizing links 24 avoid the top edge of the cabinet body 11, the above two points enable the cabinet door 12 to have the conditions to continue to flip up and open until the cabinet door 12 is flipped up and opened to a maximum limit.

[0041] Embodiment 2: Reference Figure 9-11 The difference between this embodiment and the first embodiment is that the synchronization rod 31 in this embodiment is of adjustable length, so as to adapt to the installation of cabinet modules 1 of different widths.

[0042] In this embodiment, the synchronization rod 31 specifically includes a linkage rod 51, two groups of telescopic rods 52 and two groups of gap elimination mechanisms 53; wherein, the linkage rod 51 and the two groups of telescopic rods 52 are all plum blossom circular tube structures, the linkage rod 51 and the two groups of telescopic rods 52 are coaxially arranged, the two groups of telescopic rods 52 are close to each other at one end (defined as the inner end) and are respectively slidably embedded in the two ends of the linkage rod 51, and the two groups of telescopic rods 52 are far away from each other at one end (defined as the outer end) and are both configured as rectangular tube structures adapted to the connecting groove 33, and the outer ends of the two groups of telescopic rods 52 are respectively embedded in the two groups of connecting grooves 33; the two groups of gap elimination mechanisms 53 are respectively arranged inside the two groups of telescopic rods 52, and the gap elimination mechanisms 53 are used to eliminate the matching gap between the telescopic rod 52 and the connecting groove 33, and between the telescopic rod 52 and the linkage rod 51, which is beneficial for the two groups of stabilizing connecting rods 24 to rotate synchronously with the help of the synchronization module 3, thereby improving the stability of the cabinet door 12 during the upward flipping and opening process.

[0043] In the above, the gap elimination mechanism 53 is used to eliminate the matching gap between the telescopic rod 52 and the connecting groove 33, and between the telescopic rod 52 and the linkage rod 51, which is specifically manifested as follows in this embodiment: The gap elimination mechanism 53 specifically includes a first propulsion block 531, a second propulsion block 532, a central axis 533 and a rotating assembly 534; wherein the telescopic rod 52 of the plum blossom tube structure is provided with an installation cavity 535 inside, and the telescopic rod 52 is provided with two groups of symmetrically arranged movable holes 536 at the matching gap position between the telescopic rod 52 and the connecting groove 33, that is, the connection between the plum blossom tube structure section and the rectangular tube structure section of the telescopic rod 52 is provided with two groups of symmetrically arranged movable holes 536; the central axis 533 is coaxially arranged with the telescopic rod 52, and the central axis 533 is rotatably arranged in the installation cavity 535 of the telescopic rod 52 through a preset micro bearing seat, the first propulsion block 531 is threadedly connected to the central axis 533, the outer periphery of the first propulsion block 531 and the inner periphery of the telescopic rod 52 are slidably engaged, and the first propulsion block 531 is fixedly provided with two groups of gaskets 5 37, the thickness of the two groups of gaskets 537 gradually becomes thinner in the direction away from the first propulsion block 531, forming the function of an inclined wedge block, the two groups of gaskets 537 respectively penetrate the two groups of movable holes 536, and the two groups of gaskets 537 are inserted into the matching gap between the telescopic rod 52 and the connecting groove 33; the second propulsion block 532 is threadedly connected to the central axis 533, and the outer periphery of the second propulsion block 532 and the inner periphery of the telescopic rod 52 are also slidably connected, and the second propulsion block 532 is fixedly provided with an outward expansion cone 538, and the cross-section of the outward expansion cone 538 gradually increases in the direction away from the second propulsion block 532, and the inner end of the telescopic rod 52 is provided with a plurality of groups of evenly distributed outward expansion slots 539, so that the inner end of the telescopic rod 52 has the function of elastic expansion; the rotating component 534 is arranged between the telescopic rod 52 and the connecting member 32, and the rotating component 534 is used to drive the central axis 533 to rotate.

[0044] When the rotating assembly 534 drives the central axis 533 to rotate forward, the first pushing block 531 and the second pushing block 532 both move in the direction close to the connecting piece 32. The first pushing block 531 pushes the gasket 537 to pass through the movable hole 536 and insert into the matching gap between the telescopic rod 52 and the connecting groove 33. The second pushing block 532 pulls the outward expansion cone 538 to embed into the inner end of the telescopic rod 52, so that the inner end of the telescopic rod 52 elastically expands and presses against the inner periphery of the linkage rod 51. At this time, the matching gap between the telescopic rod 52 and the connecting groove 33 is eliminated by the gasket 537, and the matching gap between the telescopic rod 52 and the linkage rod 51 is eliminated as much as possible due to the elastic expansion of the inner end of the telescopic rod 52, so that the connecting piece 32, the linkage rod 51, and the two groups of telescopic rods 52 can keep synchronous rotation as much as possible, which is ultimately beneficial to the synchronous rotation of the two groups of stabilizing connecting rods 24 with the help of the synchronization module 3, thereby improving the stability of the cabinet door 12 during the upward opening process.

[0045] In the above, the rotating assembly 534 is used to drive the central shaft 533 to rotate, which is specifically manifested as follows in this embodiment: The rotating assembly 534 includes a transmission shaft 5341, a driving bevel gear 5342, a driven bevel gear 5343 and a rotating shaft 5344; wherein the transmission shaft 5341 is rotatably arranged on the rectangular tube structure section of the telescopic rod 52, and the two ends of the transmission shaft 5341 extend and are exposed to the inner wall and the outer wall of the telescopic rod 52 respectively, the driving bevel gear 5342 is fixedly arranged on the inner side end of the transmission shaft 5341, and the driven bevel gear 5343 is fixedly arranged on the central axis 533, and the driving bevel gear 5342 and the driven bevel gear 5343 are meshed; since the transmission shaft 5341 is exposed on the outer wall of the telescopic rod 52, the connecting member 32 is provided with an avoidance groove 5345 for avoiding the outer end of the transmission shaft 5341, and the connecting member 32 is also provided with a relative alignment with the transmission shaft 5341 The rotating hole 5346, the rotating shaft 5344 and the rotating hole 5346 are adapted to each other, the rotating shaft 5344 is movably arranged in the rotating hole 5346, the outer end of the rotating shaft 5344 is provided with a cross slot for easy rotation with a screwdriver, the inner end of the rotating shaft 5344 is provided with a hexagonal column 5347, the outer end of the transmission shaft 5341 is provided with a hexagonal groove 5348 which is plugged and adapted to the hexagonal column 5347, the connecting piece 32 is also provided with a magnet 5349 which is magnetically matched with the rotating shaft 5344, the magnet 5349 is a permanent magnet 5349, the magnet 5349 can adsorb the rotating shaft 5344 so that the rotating shaft 5344 always has a tendency to disengage from the hexagonal groove 5348, and is used to limit the rotating shaft 5344 from disengaging from the rotating hole 5346.

[0046] Because the avoidance groove 5345 can avoid the transmission shaft 5341, the outer end of the telescopic rod 52 can be smoothly embedded in the connecting groove 33, and after the outer end of the telescopic rod 52 is completely embedded in the connecting groove 33, the transmission shaft 5341 and the rotating shaft 5344 are aligned. At this time, first use a screwdriver to push the rotating shaft 5344 to break away from the adsorption of the magnet 5349 until the rotating shaft 5344 moves to the hexagonal column 5347 and the hexagonal groove 5348 are connected, and then use a screwdriver to rotate the rotating shaft 5344. The rotating shaft 5344 drives the bevel gear transmission through the transmission shaft 5341, and the rotating component 534 can be used to drive the central shaft 533 to rotate.

[0047] In this embodiment, the gasket 537 is inserted into the fitting gap between the telescopic rod 52 and the connecting groove 33 and abuts against the outer end of the transmission shaft 5341. Friction is formed between the gasket 537 and the transmission shaft 5341, making it difficult for the transmission shaft 5341 to rotate autonomously, thereby improving the structural stability.

[0048] Implementation principle: When the rotating assembly 534 drives the central shaft 533 to rotate forward, the first push block 531 and the second push block 532 both move in the direction close to the connecting member 32, the first push block 531 pushes the gasket 537 to penetrate the movable hole 536 and insert into the matching gap between the telescopic rod 52 and the connecting groove 33, and the second push block 532 pulls the outward expansion cone 538 to embed into the inner end of the telescopic rod 52, so that the inner end of the telescopic rod 52 elastically expands and presses against the inner periphery of the linkage rod 51. At this time, the matching gap between the telescopic rod 52 and the connecting groove 33 is eliminated by the gasket 537, and the matching gap between the telescopic rod 52 and the linkage rod 51 is eliminated due to the elastic expansion of the inner end of the telescopic rod 52. The amount is eliminated, so that the connecting piece 32, the linkage rod 51, and the two groups of telescopic rods 52 can maintain synchronous rotation as much as possible, which is ultimately beneficial to the synchronous rotation of the two groups of stabilizing links 24 with the help of the synchronization module 3, thereby improving the stability of the cabinet door 12 during the upward opening process; in the process of the rotating component 534 driving the central axis 533 to rotate in the opposite direction, the first pushing block 531 and the second pushing block 532 both move in the direction away from the connecting piece 32, and the first pushing block 531 drives the gasket 537 to exit the fitting gap between the telescopic rod 52 and the connecting groove 33, and the second pushing block 532 pushes the outward expansion cone 538 to exit the inner end of the telescopic rod 52, so that the telescopic rod 52 and the linkage rod 51 can slide to adjust the length.

[0049] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
