Description

Technical Field

[0001] This utility model relates to the technical field of flip-type opening and closing mechanisms for laser TV cabinets, specifically to a motion mechanism and cabinet body for a flip-type opening and closing mechanism. Background Technology

[0002] Generally, cabinets are equipped with opening and closing mechanisms (such as drawers) to allow items to be retrieved or used when the mechanism is open, and to allow items to be stored away and maintain the compactness of the cabinet structure when the mechanism is closed. However, a typical sliding opening and closing mechanism results in a larger cabinet depth (the distance from the front to the back of the cabinet), making the cabinet look bulky and less high-end.

[0003] To address at least one of the aforementioned problems with cabinets using general sliding opening and closing mechanisms, some flip-type opening and closing mechanisms for cabinets have been introduced on the market. However, flip-type opening and closing mechanisms generally suffer from the problem that the connection point on the cabinet is difficult to determine. This is more pronounced when there is more than one set of flipping components that can flip relative to the fixed cabinet body. As a result, repeated adjustments are required during cabinet manufacturing to finally determine the appropriate installation point for the flip-type opening and closing mechanism, leading to low manufacturing efficiency. Utility Model Content

[0004] To solve at least one of the aforementioned problems, according to one aspect of the present invention, a motion mechanism for a flip-type opening and closing mechanism is provided.

[0005] The motion mechanism for the flip-type opening and closing mechanism includes a first rod, and a first link group and a second link group, each including a set of rods. The first rod is rotatably connected to the first link group and the second link group via a first pivot axis and a second pivot axis, respectively. The first link group is configured to rotate relative to one fixed point of the first flipping element of the flip-type opening and closing mechanism. The second link group is configured to rotate relative to another fixed point of the first flipping element of the flip-type opening and closing mechanism and one fixed point of the cabinet body. The first rod, the first link group, and the second link group are configured such that when the first rod reciprocates along the direction of the line connecting the first pivot axis and the second pivot axis, and the direction of the line connecting the first pivot axis and the second pivot axis remains unchanged, the first link group and the second link group can drive the first flipping element to move, thereby realizing the opening and closing of the flip-type opening and closing mechanism.

[0006] When the motion mechanism of this application drives the first flipping member to move, the first rod body reciprocates along the line connecting the first pivot axis and the second pivot axis set thereon, and the direction of the line connecting the first pivot axis and the second pivot axis remains unchanged. Due to this invariant, the pivot connection position of the first link group and the second link group can be determined relatively quickly, thereby improving the manufacturing efficiency of the flipping opening and closing mechanism. The second link group is set to be able to rotate relative to one of the fixed points of the cabinet body, which can ensure the stability of the entire motion mechanism.

[0007] In some embodiments, the second linkage group is further configured to rotate relative to the fixed point of the second flipping member of the flipping opening and closing mechanism, so that the first rod body reciprocates along the direction of the line connecting the first pivot axis and the second pivot axis, and when the direction of the line connecting the first pivot axis and the second pivot axis remains unchanged, the first linkage group and the second linkage group can drive the first flipping member and the second flipping member to move respectively, so as to realize the opening and closing of the flipping opening and closing mechanism.

[0008] Since the motion mechanism of this application can drive the first flipping member and the second flipping member to move, the first flipping member can approach the second flipping member before and after the movement. When part of the first flipping member is located at the front of the cabinet and part of the second flipping member is located at the top of the cabinet, the height of the cabinet can be as low as possible to facilitate the miniaturization of the cabinet.

[0009] In some embodiments, the first linkage group includes a second rod body, which is pivotally connected to the first rod body via a first pivot shaft. The first linkage group is rotatable relative to a fixed point of the first flip member of the flip-type opening and closing mechanism, which is achieved by the second rod body being rotatable relative to a fixed point of the first flip member. Thus, when the first flip member is fixed relative to the flip-out drawer of the cabinet, the fixed point for the second rod body to rotate relative to the first flip member can be set at a specific position on the first flip member. This specific position allows the end of the first flip member closest to the rear end of the cabinet to be closest to the rear end of the cabinet when the flip-type opening and closing mechanism is opened, so that the distance of the end of the first flip member furthest from the rear end of the cabinet when the flip-type opening and closing mechanism is opened is minimized, thereby minimizing the depth of the flip-type opening and closing mechanism in the open state (at this time, the distance from the end of the first flip member furthest from the rear end of the cabinet to the rear end of the cabinet).

[0010] In some embodiments, the motion mechanism for the flip-type opening and closing mechanism further includes a drive device for driving the first rod to reciprocate along the line connecting the first and second pivot axes. Thus, the first linkage group and the second linkage group can be moved by driving the first rod through the drive device, thereby enabling automation of the motion mechanism through programming.

[0011] In some embodiments, the second linkage is configured such that when the first flipper moves from a closed state to an open state or from an open state to a closed state relative to the cabinet body, it can drive the second flipper to move from a closed state to an open state and then back to a closed state relative to the cabinet body. Thus, by using the second linkage to drive the second flipper to an open state relative to the cabinet body, the second flipper is prevented from obstructing the movement of the first flipper between the open and closed states relative to the cabinet body. Furthermore, when the first flipper is in a closed state relative to the cabinet body, the second flipper is also in a closed state relative to the cabinet body, ensuring the compactness of the structure of the motion mechanism and the closed states of the first and second flippers.

[0012] In some embodiments, the second linkage group includes a third link and a fourth link; the third link is pivotally connected to the first link via a second pivot axis; the third link is also pivotally connected to the fourth link; the second linkage group is configured to rotate relative to another fixed point of the first flipping member of the flipping opening and closing mechanism, and is able to rotate relative to another fixed point of the first flipping member via the fourth link; the second linkage group is configured to rotate relative to one fixed point of the cabinet body, and is achieved by the fourth link rotating relative to one fixed point of the cabinet body. Because the second linkage group includes at least two pivotally connected rods (the third rod and the fourth rod), the position of the fixed point of the fourth rod relative to the first flipping member is more flexible and adjustable. In particular, when the first linkage group includes the second rod, the position of the fixed point of the fourth rod relative to the first flipping member can be set such that the line connecting the fixed point of the second rod relative to the first flipping member is parallel to and perpendicular to the line connecting the first pivot axis and the second pivot axis when the flipping opening and closing mechanism is open and closed, respectively. This facilitates the confirmation of the positions of the fixed points of the second and fourth rods relative to the first flipping member and achieves the compactness of the flipping opening and closing mechanism.

[0013] In some embodiments, the line connecting the fixed points where the fourth link and the first linkage rotate relative to the first flipping member are perpendicular to and parallel to the line connecting the first pivot axis and the second pivot axis, respectively, when the flip-type opening and closing mechanism is opened and closed. This facilitates the confirmation of the positions of the fixed points where the second and fourth links rotate relative to the first flipping member and achieves the compactness of the flip-type opening and closing mechanism.

[0014] In some embodiments, the motion mechanism for the flip-opening mechanism further includes a first mounting base that is pivotally connected to the first linkage and the fourth rod and detachably connected to the first flipping element. Thus, when the motion mechanism for the flip-opening mechanism is used on a cabinet, it can be adapted to cabinets of various sizes by detachably connecting the first mounting base to the first flipping element of the cabinet (the first flipping element can be, for example, a drawer of the cabinet) (adjusting the position of the first mounting base relative to the first flipping element, or installing it on cabinets of different sizes).

[0015] In some embodiments, the second linkage group further includes a fifth link that can rotate relative to the fixed point of the first and second flipping members. Thus, the motion mechanism can simultaneously drive the first flipping member through the first linkage group, while the first link sequentially drives the fifth link through the third and fourth links, and the first linkage group also limits the fifth link, thereby driving the second flipping member to move according to a preset motion pattern. This ensures the compactness of the flipping opening and closing mechanism while preventing the second flipping member from obstructing the movement of the first flipping member.

[0016] In some embodiments, the first linkage group is rotatable relative to one fixed point of the first flipping member of the flip-type opening and closing mechanism, which is achieved by pivotally connecting the first linkage group to the first mounting base; the fourth rod is rotatable relative to another fixed point of the first flipping member of the flip-type opening and closing mechanism, which is achieved by pivotally connecting the fourth rod to the first mounting base. Therefore, the motion mechanism of this application can be first integrated onto the first mounting base, and then the first mounting base can be detachably connected to the first flipping member, thus achieving rapid installation of the motion mechanism and adaptability to cabinets of different specifications.

[0017] In some embodiments, the pivot axis connecting the third and fourth rods is located between a fixed point where the fourth rod rotates relative to the first flipping member and a fixed point where it rotates relative to the cabinet body. This ensures the compactness of the motion mechanism.

[0018] In some embodiments, the motion mechanism for the flip-opening mechanism further includes a second mounting base that is pivotally connected to the fifth rod and detachably connected to the second flipping member. Thus, when the motion mechanism for the flip-opening mechanism is used on a cabinet, it can be adapted to cabinets of various sizes by means of the detachable connection between the second mounting base and the second flipping member of the cabinet.

[0019] According to another aspect of this utility model, a cabinet is provided.

[0020] The cabinet includes the aforementioned motion mechanism for the flip-type opening and closing mechanism. Since the direction of the line connecting the first pivot axis and the second pivot axis remains constant, this can be used as a reference to quickly determine the pivot connection position of the first linkage group and the second linkage group, thereby improving the manufacturing efficiency of the flip-type opening and closing mechanism.

[0021] In some embodiments, the cabinet further includes a cabinet body, a first flipping element, and a second flipping element; the cabinet body is used to install a drive device capable of driving the first rod to reciprocate along a constant line connecting the first and second pivot axes.

[0022] Since the motion mechanism of this application can drive the first flipping member and the second flipping member to move, the first flipping member can approach the second flipping member before and after the movement. When part of the first flipping member is located at the front of the cabinet and part of the second flipping member is located at the top of the cabinet, the height of the cabinet can be as low as possible to facilitate the miniaturization of the cabinet. Moreover, the first linkage group and the second linkage group can be driven to move by the first rod body driven by the driving device, so as to realize the automation of the motion mechanism through programming.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] Figures 1 to 4 The schematic diagram shows the motion mechanism 20 for the flip-type opening and closing mechanism according to the first embodiment of the present invention.

[0044] like Figures 1 to 4As shown, the motion mechanism 20 for the flip-type opening and closing mechanism includes a first rod 21, a second rod 221, a third rod 231, and a fourth rod 232; the first rod 21 and the second rod 221 are pivotally connected via a first pivot shaft 211; the first rod 21 and the third rod 231 are pivotally connected via a second pivot shaft 212; the third rod 231 and the fourth rod 232 are pivotally connected via a fourth pivot shaft 2311; the second rod 221 is configured to be able to rotate relative to the flip-type opening and closing mechanism. The first flipping member 31 can rotate at one fixed point. For example, the second rod 221 is pivotally connected to the first flipping member 31 via a third pivot shaft 2211. The fourth rod 232 is configured to rotate relative to another fixed point of the first flipping member 31 of the flipping opening and closing mechanism. For example, the fourth rod 232 is pivotally connected to the first flipping member 31 via a fifth pivot shaft 2321. The fourth rod 232 is also used to pivotally connect to a fixed member. For example, the fourth rod 232 is pivotally connected to a fixed member via a sixth pivot shaft 2322. The fixed component is pivotally connected, and the corresponding point of the sixth pivot axis 2322 on the cabinet body 33 is the fixed point for the fourth rod 232 to rotate relative to the cabinet body 33; the fourth rod 232 is also configured to be pivotally mounted relative to the cabinet body 33 to ensure the stability of the entire motion mechanism 20; the fixed component is a relative fixed component, that is, with the fixed component as a reference, the first flipping component 31 flips relative to the fixed component under the drive of the motion mechanism 20; when the motion mechanism 20 is used on a cabinet, the fixed component can be the cabinet body 33. The first rod 21, the second rod 221, the third rod 231, and the fourth rod 232 are configured such that when the first rod 21 reciprocates along the line connecting the first pivot axis 211 and the second pivot axis 212, and the direction of the line connecting the first pivot axis 211 and the second pivot axis 212 remains unchanged (e.g., always vertical), the second rod 221, the third rod 231, and the fourth rod 232 can drive the first flipping member 31 to move, thereby realizing the opening of the flipping opening and closing mechanism (e.g., ...). Figure 2 and Figure 4 As shown, for example, the first flipping member 31 moves to the open state relative to the fixed member) and closed (as shown). Figure 1 and Figure 3 As shown, for example, the first flipper 31 rotates to a closed state relative to the fixed member.

[0045] When the motion mechanism 20 of this application drives the first flipping member 31 to move, the first rod 21 reciprocates along the line connecting the first pivot axis 211 and the second pivot axis 212 provided thereon, and the direction of the line connecting the first pivot axis 211 and the second pivot axis 212 remains unchanged. Due to this invariant, the positions of the second rod 221 and the fourth rod 232 pivotally connected to the first flipping member 31 can be determined relatively quickly, that is, the positions of the third pivot axis 2211 and the fifth pivot axis 2321 can be determined relatively quickly, thereby improving the manufacturing efficiency of the flipping opening and closing mechanism; moreover, when the first flipping member 31 is relatively fixed to the flipping drawer of the cabinet (or is a drawer), the pivot axis of the second rod 221 pivotally connected to the first flipping member 31 can be set at a specific position of the first flipping member 31. This specific position allows the end of the first flipping member 31 near the rear end of the cabinet to be opened when the flipping opening and closing mechanism is opened. The first rotating member 31 is positioned closest to the rear end of the cabinet so that when the flip-type opening and closing mechanism is opened, the distance from the rear end of the first rotating member 31 to the rear end of the cabinet is minimized, thus minimizing the depth of the flip-type opening and closing mechanism in its open state (the distance from the rear end of the first rotating member 31 to the rear end of the cabinet). Simultaneously, since the first rod 21 is pivotally connected to the fourth rod 232 via the third rod 231, the pivotal connection position of the fourth rod 232 to the first rotating member 31 is more flexible and adjustable. Furthermore, by setting the pivotal connection position of the fourth rod 232 to the first rotating member 31 such that the line connecting the second rod 221 to the first rotating member 31 is parallel to and perpendicular to the line connecting the first pivot axis 211 and the second pivot axis 212 when the flip-type opening and closing mechanism is open and closed, respectively, the positions of the second rod 221 and the fourth rod 232 on the first rotating member 31 can be confirmed, and the compactness of the flip-type opening and closing mechanism can be achieved.

[0046] In some embodiments, such as Figure 1 and Figure 3 As shown, the line connecting the pivot axis of the fourth rod 232 and the second rod 221 to the first flipping member 31 is parallel to the line connecting the first pivot axis 211 and the second pivot axis 212 when the flipping opening and closing mechanism is closed (that is, at this time, the line connecting the fifth pivot axis 2321 and the third pivot axis 2211 is parallel to the line connecting the first pivot axis 211 and the second pivot axis 212), that is, the line connecting the third pivot axis 2211 and the fifth pivot axis 2321 is parallel to the line connecting the first pivot axis 211 and the second pivot axis 212 when the flipping opening and closing mechanism is closed. Figure 2 and Figure 4As shown, the line connecting the fourth rod 232 and the second rod 221 to the pivot axis of the first flipping member 31 is perpendicular to the line connecting the first pivot axis 211 and the second pivot axis 212 when the flipping opening and closing mechanism is opened (that is, at this time the line connecting the fifth pivot axis 2321 and the third pivot axis 2211 is perpendicular to the line connecting the first pivot axis 211 and the second pivot axis 212), so as to confirm the position of the second rod 221 and the fourth rod 232 on the first flipping member 31 and to achieve the compactness of the flipping opening and closing mechanism.

[0047] In some embodiments, such as Figures 1 to 4 As shown, the pivot axis that pivotally connects the third rod 231 and the fourth rod 232 is located between the pivot axis that pivotally connects the fourth rod 232 and the first flipping member 31 and the pivot axis that pivotally connects to the fixed member. That is, the fourth pivot axis 2311 is located between the fifth pivot axis 2321 and the sixth pivot axis 2322 to ensure the compactness of the motion mechanism 20.

[0048] In some embodiments, such as Figures 1 to 4 As shown, in order to ensure the structural stability of the motion mechanism 20 and the quick connection with the first flipping member 31, the motion mechanism 20 also includes a first connecting member 24; the second rod 221 is pivotally connected to the first connecting member 24 through a third pivot shaft 2211; the fourth rod 232 is pivotally connected to the first connecting member 24 through a fifth pivot shaft 2321; the first connecting member 24 is used to fix itself to the first flipping member 31.

[0049] In some embodiments, all pivot axes in this application are arranged parallel to each other to ensure the compactness of the structure of the motion mechanism 20 used in the flip-type opening and closing mechanism.

[0050] like Figure 1 As shown, the second rod 221 constitutes the first link group 22 in one embodiment of this application.

[0051] like Figures 1 to 4 As shown, the third rod 231 and the fourth rod 232, which are pivotally connected by the fourth pivot shaft 2311, constitute the second linkage 23 of an embodiment of this application.

[0052] Figures 5 to 9 The schematic diagram shows a motion mechanism 20 for a flip-type opening and closing mechanism according to a second embodiment of the present invention.

[0053] like Figures 5 to 9As shown, the motion mechanism 20 for the flip-type opening and closing mechanism in this embodiment further includes a fifth rod 233 based on the motion mechanism 20 for the flip-type opening and closing mechanism in the first embodiment; the fifth rod 233 is pivotally connected to the first flip member 31 through the seventh pivot shaft 2331; the fifth rod 233 is pivotally connected to the second flip member 32 through the eighth pivot shaft 2332. Therefore, the motion mechanism 20 can simultaneously drive the first flipping member 31 to move via the second rod 221, and simultaneously drive the fifth rod 233 via the third rod 231 and the fourth rod 232, and the second rod 221 can restrict the fifth rod 233, thereby driving the second flipping member 32 to move according to a preset motion pattern. On the one hand, this avoids the second flipping member 32 from obstructing the movement of the first flipping member 31, and on the other hand, it allows the first flipping member 31 to approach the second flipping member 32 before and after the movement. When part of the first flipping member 31 is located at the front of the cabinet and part of the second flipping member 32 is located at the top of the cabinet, the height of the cabinet can be as low as possible to facilitate the miniaturization of the cabinet.

[0054] In some implementations, such as Figures 7 to 9 As shown, the third rod 231, the fourth rod 232, and the fifth rod 233 are configured such that, in the self-closed state between the first flipping member 31 and the fixed member (e.g., Figure 7 (As shown) Move to the open state (e.g.) Figure 8 (as shown) or when it moves from the open state to the closed state, it can drive the second flipping member 32 to move relative to the fixed member from the closed state (as shown). Figure 7 or Figure 8 (as shown) to the open state (e.g.) Figure 9 As shown) it moves back to the closed state (as shown) Figure 7 or Figure 8 (As shown). Thus, the second flipping member 32 can be driven to the open state relative to the fixed member by the second linkage group 23, so as to avoid the second flipping member 32 from hindering the movement of the first flipping member 31 between the open and closed states relative to the fixed member; moreover, when the first flipping member 31 is in the closed state relative to the fixed member, the second flipping member 32 is also in the closed state relative to the fixed member, so as to ensure the compactness of the structure of the motion mechanism 20 with the first flipping member 31 and the second flipping member 32 in the closed state.

[0055] In some embodiments, such as Figures 5 to 8 As shown, in order to ensure the structural stability of the motion mechanism 20 and the quick connection with the first flipping member 31, the motion mechanism 20 also includes a second connecting member 25; the fourth rod 232 is pivotally connected to the second connecting member 25 through the fifth pivot shaft 2321; the fifth rod 233 is pivotally connected to the second connecting member 25 through the seventh pivot shaft 2331; the second connecting member 25 is used to fix itself to the first flipping member 31.

[0056] In some embodiments, such as Figure 5 and Figure 6 As shown, in order to ensure the quick connection between the motion mechanism 20 and the second flipping member 32, the motion mechanism 20 also includes a third connecting member 26; the fifth rod 233 is pivotally connected to the third connecting member 26 through the eighth pivot shaft 2332; the third connecting member 26 is pivotally connected to the fixing member through the ninth pivot shaft 261, that is, the relative positions of the ninth pivot shaft 261 and the sixth pivot shaft 2322 remain constant; the third connecting member 26 is used to fix itself to the second flipping member 32.

[0057] In some embodiments, all pivot axes in this application are arranged parallel to each other to ensure the compactness of the structure of the motion mechanism 20 used in the flip-type opening and closing mechanism.

[0058] like Figures 5 to 9 As shown, the third rod 231, the fourth rod 232 and the fifth rod 233, which are pivotally connected by the fourth pivot shaft 2311, constitute the second linkage 23 of an embodiment of this application.

[0059] Figure 10 The schematic diagram shows the motion mechanism 20 for a flip-type opening and closing mechanism according to a third embodiment of the present invention.

[0060] like Figure 10 As shown, the motion mechanism 20 for the flip-type opening and closing mechanism in this embodiment further includes a drive device 27 for driving the first rod 21 to reciprocate along the line connecting the first pivot axis 211 and the second pivot axis 212, based on the motion mechanism 20 for the flip-type opening and closing mechanism in the first or second embodiment. Thus, the first first linkage group 22 and the second linkage group 23 can be moved by driving the first rod 21 through the drive device 27, thereby automating the motion mechanism 20 through programming.

[0061] As one embodiment of the drive device 27, such as Figure 10 As shown, the drive device 27 includes a cylinder 271 (or a hydraulic cylinder) and a moving mechanism 272. The moving mechanism 272 is configured to drive the first rod 21 to reciprocate along the line connecting the first pivot axis 211 and the second pivot axis 212 under the drive of the cylinder 271. In some embodiments, the cylinder body of the cylinder 271 is fixedly disposed relative to the fixing member, that is, the base of the drive device 27 is fixedly disposed relative to the fixing member.

[0062] As one embodiment of the mobile mechanism 272, reference continues. Figure 10As shown, the moving mechanism 272 includes a first guide rail 2721 and a first slider 2722 that are adapted to each other; the first guide rail 2721 is fixedly disposed relative to the fixing member and / or the cylinder body of the cylinder 271, and is disposed along the line connecting the first pivot axis 211 and the second pivot axis 212; the first rod body 21 is fixedly disposed relative to the first slider 2722.

[0063] As another embodiment of the drive device 27, the drive device 27 includes a moving mechanism 272 of another implementation. This moving mechanism 272 includes mutually adapted gears and racks; the rack is fixed relative to a fixed member and is arranged along the line connecting the first pivot axis 211 and the second pivot axis 212; the motor drives the gear to rotate relative to the rack while moving along the extension direction of the rack, and the direction of the gear's movement along the rack can be changed by changing the driving direction of the motor. The first rod 21 is fixed relative to the motor base; the fourth rod 232 is pivotally mounted relative to the rack via a sixth pivot axis 2322.

[0064] Figure 11 The schematic diagram shows the motion mechanism 20 for the flip-type opening and closing mechanism according to the fourth embodiment of the present invention.

[0065] like Figure 11 As shown, the motion mechanism 20 for the flip-type opening and closing mechanism in this embodiment is an improvement on the motion mechanism 20 for the flip-type opening and closing mechanism in the first, second, or third embodiment. The improved motion mechanism 20 for the flip-type opening and closing mechanism further includes a first mounting base 28; the second rod 221 is pivotally connected to the first flipping member 31, and the second rod 221 is pivotally connected to the first mounting base 28 through a third pivot shaft 2211, and the first mounting base 28 is detachably connected to the first flipping member 31. In this configuration, the corresponding position of the third pivot axis 2211 on the first flip member 31 is the fixed point for the rotation of the second rod 221 relative to the first flip member 31. The fourth rod 232 is pivotally connected to the first flip member 31, and the fourth rod 232 is pivotally connected to the first mounting base 28 via the fifth pivot axis 2321. This is achieved by detachably connecting the first mounting base 28 to the first flip member 31. Thus, when this motion mechanism 20 for the flip-type opening and closing mechanism is used on a cabinet, it can adapt to cabinets of various sizes by detachably connecting the first mounting base 28 to the first flip member 31 of the cabinet.

[0066] In some embodiments, continue to refer to Figure 11As shown, the improved motion mechanism 20 for the flip-type opening and closing mechanism also includes a second mounting base 29; the fifth rod 233 and the second flip member 32 are pivotally connected, with the fifth rod 233 pivotally connected to the second mounting base 29 via an eighth pivot shaft 2332, and the second mounting base 29 and the second flip member 32 are detachably connected. The corresponding position of the eighth pivot shaft 2332 on the second flip member 32 is the fixed point for the fifth rod 233 to rotate relative to the second flip member 32. Therefore, when this motion mechanism 20 for the flip-type opening and closing mechanism is used on a cabinet, it can adapt to cabinets of various sizes by detachably connecting the second mounting base 29 to the second flip member 32 of the cabinet.

[0067] In some embodiments, to facilitate quick connection between the drive device 27 and the fourth rod 232 relative to the fixing member, continue to refer to Figure 11 As shown, the motion mechanism 20 for the flip-type opening and closing mechanism also includes a third mounting base 40. When the drive device 27 includes a cylinder 271, a first guide rail 2721, and a first slider 2722, the cylinder body of the cylinder 271 and the first guide rail 2721 are fixedly disposed relative to the third mounting base 40, and the fourth rod 232 is pivotally disposed relative to the third mounting base 40 via a sixth pivot shaft 2322. The third mounting base 40 is used for detachable connection with a fixing component (e.g., cabinet body 33). When the drive device 27 includes a motor, a gear, and a rack, the rack is fixedly disposed relative to the third mounting base 40, and the fourth rod 232 is pivotally disposed relative to the third mounting base 40 via a sixth pivot shaft 2322. The third mounting base 40 is used for detachable connection with a fixing component (e.g., cabinet body 33).

[0068] In other embodiments, the first linkage 22 includes at least two pivotally connected rods, one of which is pivotally connected to the first rod 21, and the other is pivotally connected to the first flipping member 31. As long as the first linkage 22, driven by the first rod 21 and constrained by the second linkage 23, can achieve reciprocating motion of the first rod 21 along the line connecting the first pivot axis 211 and the second pivot axis 212, and the direction of the line connecting the first pivot axis 211 and the second pivot axis 212 remains unchanged, the opening and closing of the flipping opening and closing mechanism can be achieved by driving the first flipping member 31 through the first linkage 22 and the second linkage 23.

[0069] Figures 12 to 15 The cabinet is schematically shown according to one embodiment of the present invention.

[0070] like Figure 13As shown, the cabinet includes the aforementioned motion mechanism 20 for the flip-type opening and closing mechanism. Since the direction of the line connecting the first pivot shaft 211 and the second pivot shaft 212 remains unchanged, the pivot connection position of the first link group 22 and the second link group 23 can be determined relatively quickly using this as a reference, thereby improving the manufacturing efficiency of the flip-type opening and closing mechanism.

[0071] In some embodiments, such as Figures 13 to 15 As shown, the cabinet also includes a cabinet body 33, a first flipping component 31, and a second flipping component 32; the cabinet body 33 is used to install a drive device 27 that can drive the first rod 21 to reciprocate along the direction of the line connecting the first pivot axis 211 and the second pivot axis 212.

[0072] Because the motion mechanism 20 of this application can drive the first flipping member 31 and the second flipping member 32 to move, the first flipping member 31 and the second flipping member 32 move to the point where the cabinet is open (e.g. Figure 14 and Figure 15 (as shown) or closed (such as) Figure 12 and Figure 13 As shown, the first flipping member 31 can approach the second flipping member 32 before and after the movement. When part of the first flipping member 31 is located at the front of the cabinet and part of the second flipping member 32 is located at the top of the cabinet, the height of the cabinet can be as low as possible to facilitate the miniaturization of the cabinet. Moreover, the first linkage group 22 and the second linkage group 23 can be driven to move by the first rod 21 driven by the drive device 27, so as to realize the automation of the motion mechanism 20 through programming.

[0073] In this invention, the connection or installation is a fixed connection unless otherwise specified. A fixed connection can be implemented as a detachable or non-detachable connection commonly used in the prior art. A detachable connection can be implemented using existing technologies, such as threaded connections or keyed connections. A non-detachable connection can also be implemented using existing technologies, such as welding or adhesive bonding.

[0074] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
