Description

Technical Field

[0001] The utility model relates to an opening and closing mechanism, in particular to an opening and closing mechanism and a laser TV cabinet provided with the opening and closing mechanism. Background Art

[0002] Laser TV is a TV product that uses laser light source as the display light source. It combines the characteristics of traditional projection technology and modern TV technology to provide a new type of large-screen display solution.

[0003] To protect laser TVs and maintain a clean and tidy home environment, concealed laser TV cabinets have been introduced. Currently, the most common concealed laser TV cabinets on the market include sliding (drawer-sliding) and flip-up (drawer-flipping) models. With sliding laser TV cabinets, the drawer holding the laser TV horizontally slides open to facilitate projection. With flip-up laser TV cabinets, the drawer holding the laser TV vertically flips open until the laser TV is horizontal, facilitating projection.

[0004] However, both of these two common concealed laser TV cabinets have the problem of the cabinet body occupying a large space: for example, due to the limitation of the width of the laser TV, the width (depth) of the sliding laser TV cabinet is wider; for another example, for the flip-up laser TV cabinet, in order to avoid the upper part of the laser TV cabinet interfering with the flipped drawers and laser TV, the drawers in the vertical state and the upper part of the laser TV cannot be too close to the top of the laser TV cabinet, which results in a large gap between the upper part of the laser TV when placed vertically and the top of the laser TV cabinet, that is, the height of the laser TV cabinet is greater than the height of the laser TV in the vertical state, which also results in the height of the laser TV cabinet being higher. Utility Model Content

[0005] In order to solve at least one of the above problems, according to one aspect of the present invention, an opening and closing mechanism is provided.

[0006] The opening and closing mechanism includes a base body, a flip member and a moving member; the flip member is configured to be able to pivotally move back and forth between a first setting position and a first use position relative to the base body around a first pivot axis; the moving member is configured to be movably arranged on the base body; wherein, during or before the flip member moves from the first setting position to the first use position, the moving member can move from the second setting position to the second use position; and / or during or after the flip member moves from the first use position to the first setting position, the moving member can move from the second use position to the second setting position.

[0007] Therefore, when the opening and closing mechanism is used in a laser TV cabinet, even if the upper part of the laser TV installed on the flip member is in a vertical state (the flip member is in the first setting position) and is close to the top of the laser TV cabinet, the moving member can be moved from the second setting position (the moving member covers the top of the laser TV cabinet) to the second use position (the moving member opens the top of the laser TV cabinet) during or before the flip member moves from the first setting position to the first use position (the laser TV is in a horizontal state) to avoid interference of the moving member with the pivoting of the flip member, so that the structure of the laser TV cabinet provided with the opening and closing mechanism is compact.

[0008] In some embodiments, the opening and closing mechanism further includes a driving module; the driving module is configured to drive the moving part to move in the first direction and the second direction during the reciprocating movement of the moving part between the second set position and the second use position; wherein, "the driving module is configured to drive the moving part to move in the first direction) and the second direction during the reciprocating movement of the moving part between the second set position and the second use position" includes, for example, during the reciprocating movement of the moving part between the second set position and the second use position, the driving module drives the moving part to move in the first direction and the second direction at the same time, or first drives the moving part to move in the first direction and then in the second direction, or first drives the moving part to move in the second direction and then in the first direction, that is, under the drive of the driving module, the moving part does not necessarily have to move in the first direction and the second direction at the same time, and the moving part can move alternately in the first direction and the second direction. Thus, when the opening and closing mechanism is used for a laser TV cabinet, and the moving part is integrally formed or provided on the cover of the laser TV cabinet, the moving part can move in the first direction and the second direction during the reciprocating movement between the second set position and the second use position to avoid the cabinet body of the laser TV cabinet hindering the movement of the moving part.

[0009] In some embodiments, a driving module is further included; the driving module includes a first transmission unit, the first transmission unit is configured to drive the moving member to move from the second setting position to the second use position during or before the flip member moves from the first setting position to the first use position, and to drive the moving member to move from the second use position to the second setting position during or after the flip member moves from the first use position to the first setting position; or the driving module includes a first driving unit and a second transmission unit, the first driving unit and the second transmission unit are configured to drive the first driving unit to drive the second transmission unit to move the moving member from the second setting position to the second use position during or before the flip member moves from the first setting position to the first use position, and to drive the second transmission unit to move the moving member from the second use position to the second setting position during or after the flip member moves from the first use position to the first setting position. In this way, the moving member can cooperate with the movement of the flip member to avoid interference with the pivotal movement of the flip member.

[0010] In some embodiments, the first transmission unit includes a first moving structure capable of driving the moving member to move along the first direction and the second direction so that the moving member can move back and forth between the second set position and the second use position, so as to stably limit the movement direction of the moving member through the first moving structure.

[0011] In some embodiments, the first moving structure includes a first slide rail provided on the base body; and a first slider adapted to the first slide rail; the moving member is provided on the first slider; the first slide rail is configured to include a first track, a second track, and a third track connecting the first track and the second track, the first track and the second track are parallel to the first direction, and the first track is not in the extension direction of the second track, so as to accurately define the moving trajectory of the moving member by the mutually adapted first slide rail and the first slider.

[0012] In some embodiments, the first transmission unit further includes a second moving structure capable of driving the moving member to reciprocate along the second direction. Thus, the moving member can be driven to move along the second direction by the second moving structure.

[0013] In some embodiments, the first transmission unit further includes a first swinging lever, wherein a first end of the first swinging lever is pivotally mounted on the base body about a second pivot axis, and a second end of the first swinging lever is pivotally mounted on the second movable structure about a third pivot axis. Thus, the second movable structure can be driven by the pivotal movement of the first swinging lever, thereby simplifying the driving method of the second movable structure.

[0014] In some embodiments, the first transmission unit also includes a first driving mechanism for driving the first swinging rod to pivot around the second pivot axis. The first driving mechanism is pivotally connected to the flip member and the first swinging rod through a fourth pivot axis and a fifth pivot axis, respectively, so that during the process of the flip member pivoting around the first pivot member, the first swinging rod is driven to rotate around the second pivot axis through the first driving mechanism, thereby driving the second movable structure to move, and then driving the first movable structure to move, and finally driving the movable member to move.

[0015] In some embodiments, the first driving mechanism includes a second swinging rod and a third movable structure; wherein the second swinging rod is pivotally connected to the first swinging rod through a fifth pivot axis; the third movable structure is arranged on the second swinging rod, and the third movable structure is pivotally arranged on the flip member through a fourth pivot axis; the second swinging rod is also arranged to drive the first swinging rod to pivot during the movement of the flip member from the first use position to the first set position, so as to drive the first swinging rod to pivot through the second swinging rod during the movement of the flip member from the first use position to the first set position.

[0016] In some embodiments, the first transmission unit further includes at least one of a first elastic member and a second elastic member, the first elastic member being configured to have a tendency to drive the first swing lever and the second swing lever to pivot so that the movable member moves from the second set position to the second use position, and the second elastic member being configured to have a tendency to drive the first swing lever and the second swing lever to pivot so that the movable member moves from the second use position to the second set position; and / or the second swing lever is further configured to drive the first swing lever to pivot about the first pivot axis during the process of the flip member moving from the first use position to the first set position, wherein the fourth movable structure having a locking structure is provided on the second swing lever, and the fourth movable structure can abut against the first swing lever during the process of the flip member moving from the first use position to the first set position to drive the first swing lever to pivot about the second pivot axis. Thus, the relative positions of the first and second swing levers can also be adjusted by the fourth movable structure having a locking structure.

[0017] In other embodiments, the first transmission unit includes a third swing link and a fourth swing link; wherein the third swing link is pivotally connected to the movable member and the base body via a sixth pivot axis and a seventh pivot axis, respectively, and the fourth swing link is pivotally connected to the movable member and the base body via an eighth pivot axis and a ninth pivot axis, respectively. Thus, the third swing link can be driven by a driving device to rotate relative to the base body about the seventh pivot axis, and / or the fourth swing link can be driven by a driving device to rotate relative to the base body about the ninth pivot axis. Furthermore, because the third swing link also rotates relative to the movable member about the sixth pivot axis, and the fourth swing link also rotates relative to the movable member about the eighth pivot axis, the movable member, which is simultaneously constrained by the motion trajectories of the third and fourth swing links, can move smoothly.

[0018] In some embodiments, the first transmission unit further includes a fifth movable structure; the fifth movable structure is disposed on the third swing link and is pivotally mounted on the flip member via a fourth pivot axis. Thus, when the flip member pivots about the first pivot axis, the fifth movable structure can drive the third swing link to rotate relative to the base about the seventh pivot axis, while simultaneously driving the movable member to rotate relative thereto about the sixth pivot axis. Since the movable member, which rotates relative to the third swing link about the sixth pivot axis, is also constrained by the fourth swing link, the movable member can stably swing about the seventh and ninth pivot axes.

[0019] In some embodiments, the first drive unit is configured to drive the second transmission unit to reciprocate in a first direction; and the second transmission unit is configured to simultaneously reciprocate in the first direction and drive the moving member to reciprocate in a second direction. Thus, the moving member can reciprocate in the first and second directions under the drive of the first drive unit and the second transmission unit.

[0020] In some embodiments, the first driving unit includes a first linear motor and a sixth moving structure; wherein the first linear motor is arranged on the base body and is configured to drive the sixth moving structure to drive the second transmission unit along the first direction, thereby, under the drive of the first linear motor, the second transmission unit can be stably driven to reciprocate along the first direction through the sixth moving structure; and / or the second transmission unit includes a seventh moving structure, a fifth swing rod, an eighth moving structure and a third elastic member; wherein the sixth moving structure is configured to drive the seventh moving structure and the eighth moving structure to reciprocate along the first direction; the seventh moving structure is configured to drive the fifth swing rod and the third elastic member to reciprocate along the first direction, One end of the fifth swing link is pivotally mounted on the seventh movable structure around a tenth pivot axis; the eighth movable structure is configured to drive the fifth swing link, the third elastic member, and the movable member to reciprocate in the second direction, and the fifth swing link is pivotally mounted on the eighth movable structure around an eleventh pivot axis; the two ends of the third elastic member are pivotally mounted on the eighth movable structure and the seventh movable structure via the eleventh pivot axis and the twelfth pivot axis, respectively, and the third elastic member is configured to have a tendency to drive the movable member in the second set position to move from the second set position to the second use position, so that while the sixth movable structure drives the seventh movable structure to reciprocate in the first direction, the eighth movable structure can drive the movable member to reciprocate in the second direction. Thus, while the sixth movable structure drives the seventh and eighth movable structures to reciprocate in the first direction, under the combined action of the seventh movable structure, the fifth swing link, the eighth movable structure, and the third elastic member, the movable member can move in the second direction while moving in the first direction, so as to reciprocate between the second set position and the second use position.

[0021] In some embodiments, the drive module further includes a second drive unit configured to drive the flip member to pivot relative to the base about the first pivot axis. Thus, before or during the process of the second drive unit driving the flip member to pivot about the first pivot axis, the first transmission unit can drive the movable member to reciprocate between the second set position and the second use position, or the first drive unit can drive the second transmission unit to drive the movable member to reciprocate between the second set position and the second use position.

[0022] In some embodiments, the second drive unit is configured such that, while the second drive unit drives the flip member to pivot relative to the base about the first pivot axis, the second drive unit can also pivot relative to the flip member about the fourth pivot axis. Thus, while the second drive unit drives the flip member to pivot about the first pivot axis, it can also drive the first transmission unit to reciprocate the moving member between the second set position and the second use position.

[0023] In some embodiments, the fourth pivot axis is configured such that, when the flip member is in the first set position, the first pivot axis and the fourth pivot axis are arranged in a vertical direction. Thus, the second drive unit can ensure that the flip member is in a vertical position when the flip member is in the first set position. Furthermore, the second drive unit can be a second linear motor. The second base of the second linear motor can be pivotally mounted on the base body about the thirteenth pivot axis. The second push rod of the second linear motor can be pivotally mounted on the flip member about the fourth pivot axis. Thus, the second linear motor can drive the flip member to pivot about the first pivot axis.

[0024] According to another aspect of the present application, a laser TV cabinet provided with an opening and closing mechanism is provided.

[0025] The laser TV cabinet provided with an opening and closing mechanism comprises a cabinet body, a cover plate, a flip drawer and an opening and closing mechanism; wherein the opening and closing mechanism is the aforementioned opening and closing mechanism; the base body is integrally formed or relatively fixed to the cabinet body; the cover plate is integrally formed or relatively fixed to the moving part; the flip drawer is integrally formed or relatively fixed to the flip part, and the flip drawer is used to place the laser TV; a first opening is provided on the cabinet body; the cover plate is configured so that when the moving part moves to the second set position, the cover plate covers the first opening; when the moving part moves to the second use position, the cover plate opens the first opening. Thus, even if the upper part of the laser TV installed on the flip part and in a vertical state is close to the top of the laser TV cabinet, the moving part can be moved from the second set position to the second use position during or before the flip part moves from the first set position to the first use position, so as to avoid interference of the moving part with the pivoting of the flip part, thereby making the structure of the laser TV cabinet provided with an opening and closing mechanism compact.

[0045] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Figure 1 and Figure 2 The opening and closing mechanism according to the first embodiment of the present utility model is schematically shown.

[0047] like Figure 1 As shown, the opening and closing mechanism includes a base 20, a flip member 30, a moving member 40 and a first moving structure 511. The flip member 30 is pivotally mounted on the base 20 via a first pivot axis 21, and the flip member 30 can pivotally reciprocate between a first setting position and a first use position relative to the base 20 around the first pivot axis 21 (distributed as shown in FIG. Figure 1 and Figure 2 The moving member 40 is arranged on the base 20 through the first moving structure 511, and the moving member 40 can reciprocate between the second setting position and the second use position (as shown in FIG. Figure 1 and Figure 2 shown).

[0048] Figure 1 and Figure 2 The first moving structure 511 of one embodiment of the present application is shown as an example. Figure 1As shown, the first movable structure 511 includes a first slide rail 5111 fixedly mounted on the base 20; and a first slider 5112 adapted to the first slide rail 5111; the movable member 40 is mounted on the first slider 5112. As one embodiment of the first slide rail 5111, the first slide rail 5111 includes a first track a, a second track b, and a third track c connecting the first track a and the second track b. The first track a and the second track b are parallel to the first direction X (e.g., horizontal position), and the first track a is not in the extension direction of the second track b. Since the first track a is not in the extension direction of the second track b, the third track c connecting the first track a and the second track b must not be set completely along the first direction X, that is, the extension direction of the third track c has a sub-direction distributed along the second direction Y (for example, when the angle between the extension direction of the third track c and the first direction X is between 0° and 90°, the extension direction of the third track c can have a sub-direction in the first direction X and the second direction Y, and the sub-direction of the first direction X and the sub-direction of the second direction Y jointly form the extension direction of the third track c), or the third track c has a sub-direction distributed along the second direction Y. The track c extends along the second direction Y, so that when the first slider 5112 moves along the third track c, the movable member 40 will be displaced in the second direction Y driven by the first slider 5112, so that when the opening and closing mechanism is used on the laser TV cabinet, the cover body fixed relative to the movable member 40 will not interfere with the movement of the movable member 40 and the cover body during the movement of the cabinet body relative to the laser TV cabinet driven by the first moving structure 511; moreover, the movement trajectory of the movable member 40 can be accurately limited by the first slide rail 5111 and the first slider 5112 that adapt to each other.

[0049] As one specific embodiment of the first track a, Figure 1 As shown, the first track a is a through groove.

[0050] As another embodiment of the first slide rail 5111, the first slide rail 5111 is a track with an angle between 0° and 90° with the horizontal direction (i.e., it is tilted), so that when the first slider 5112 drives the moving part 40 to move along the first slide rail 5111, the moving part 40 can not only generate displacement in the first direction X, but also generate displacement in the second direction Y.

[0051] In some specific embodiments, the first slide rail 5111 can be arranged along a straight line or along an arc (not shown in the figure).

[0052] When the opening and closing mechanism is used in a laser TV cabinet, even if the upper part of the laser TV installed on the flip member 30 is in a vertical state (the flip member 30 is in the first setting position) and the movable member 40 is close to the top of the laser TV cabinet, the movable member 40 can be moved from the second setting position (the movable member 40 covers the top of the laser TV cabinet) to the second use position (the movable member 40 opens the top of the laser TV cabinet) during or before the flip member 30 moves from the first setting position to the first use position (the laser TV is in a horizontal state) to avoid interference of the movable member 40 with the pivoting of the flip member 30, so that the structure of the laser TV cabinet provided with the opening and closing mechanism is compact.

[0053] In some preferred embodiments, continue to refer to Figure 1 As shown, the opening and closing mechanism further includes a second moving structure 512 capable of driving the moving member 40 to reciprocate along the second direction Y. Thus, the moving member 40 can be driven to move along the second direction Y by the second moving structure 512.

[0054] As one specific embodiment of the second movable structure 512, Figure 1 As shown, the second movable structure 512 includes a second slide rail 5121 and a second slider 5122 that adapt to each other. The second slide rail 5121 is arranged along the second direction Y and is fixedly mounted on the first slider 5112 and the movable member 40. The second slider 5122 is pivotally mounted on the first swing arm 513 via a third pivot axis 5131. Thus, the second slider 5122 can move in the second direction Y, driving the second slide rail 5121, the first slider 5112 mounted on the second slide rail 5121, and the movable member 40 to reciprocate in the second direction Y.

[0055] As one specific embodiment of the second slide rail 5121, Figure 1 As shown, the second slide rail 5121 is a through groove integrally formed or processed on the first sliding block 5112.

[0056] In some preferred embodiments, continue to refer to Figure 1As shown, the opening and closing mechanism further includes a first swinging rod 513, a first end of the first swinging rod 513 being pivotally disposed on the base 20 around the second pivot axis 22, and a second end of the first swinging rod 513 being pivotally disposed on the second movable structure 512 around a third pivot axis 5131. Specifically, the second end of the first swinging rod 513 is pivotally disposed on the second slider 5122 around the third pivot axis 5131. Thus, the first swing arm 513 can be rotated relative to the base 20 around the second pivot axis 22, driving the second slider 5122 to perform circular motion with the second pivot axis 22 as the center point, so that the second slider 5122 is displaced in both the first direction X and the second direction Y; furthermore, the second slide rail 5121 is also displaced in the first direction X and the second direction Y under the drive of the second slider 5122; and because the movable member 40 is mounted on the second slide rail 5121, when the first swing arm 513 is rotated relative to the base 20 around the second pivot axis 22, the movable member 40 can be displaced in the first direction X and the second direction Y, thereby simplifying the driving method of the second movable structure 512. Preferably, the second pivot axis 22 and the third pivot axis 5131 are parallel to each other. Preferably, the second pivot axis 22 and the third pivot axis 5131 are arranged parallel to the first pivot axis 21 to make the structure of the opening and closing mechanism compact.

[0057] In some preferred embodiments, continue to refer to Figure 1 As shown, the opening and closing mechanism further includes a second swinging link 5141 and a third movable structure 5142. The second swinging link 5141 is pivotally connected to the first swinging link 513 via a fifth pivot axis 5132. The third movable structure 5142 is disposed on the second swinging link 5141, and the third movable structure 5142 is pivotally disposed on the flip member 30 via a fourth pivot axis 23. The second swinging link 5141 is further configured to drive the first swinging link 513 to pivot about the second pivot axis 22 during movement of the flip member 30 from the first use position to the first set position. Thus, the second swinging link 5141 drives the first swinging link 513 to pivot about the second pivot axis 22 during movement of the flip member 30 from the first use position to the first set position.

[0058] As one specific embodiment of the third mobile structure 5142, Figure 1 As shown, the third movable structure 5142 includes a third slide rail 51421 and a third slider 51422 that are adapted to each other; wherein, the flip member 30 is pivotally set on the third slider 51422 through the fourth pivot axis 23; the third slide rail 51421 is integrally formed or processed on the second swing rod 5141.

[0059] In some specific embodiments, Figure 1As shown, the third sliding block 51422 is integrally formed or processed into a through groove on the second swing rod 5141.

[0060] In some specific embodiments, continue to refer to Figure 1 As shown, the second swing arm 5141 can drive the first swing arm 513 to pivot around the first pivot axis relative to the base body 20 during the movement of the flip member 30 from the first use position to the first set position. This is achieved as follows: a fourth movable structure 5143 with a locking structure is provided on the second swing arm 5141. The fourth movable structure 5143 can abut against the first swing arm 513 during the movement of the flip member 30 from the first use position to the first set position to drive the first swing arm 513 to pivot.

[0061] As the fourth moving structure 5143 having a locking structure, Figure 1 As shown, the fourth movable structure 5143 includes a first screw hole 51431 machined in the second swing link 5141 and a first screw rod 51432 threadedly connected to the first screw hole 51431. The first screw hole 51431 and the first screw rod 51432 are arranged on the side of the first swing link 513 facing away from the fourth pivot axis 23. Therefore, by adjusting the distance that the first screw rod 51432 is screwed into the first screw hole 51431, the angle between the first swing link 513 and the second swing link 5141 when the first swing link 513 abuts against the first screw rod 51432 can be adjusted, thereby adjusting the timing at which the second swing link 5141 drives the first swing link 513 to pivot about the second pivot axis 22.

[0091] As one embodiment of the first driving unit 52, Figure 6 and Figure 9 As shown, the first driving unit 52 is configured to drive the second transmission unit 53 to reciprocate along the first direction X.

[0094] As one embodiment of the second transmission unit 53, Figure 6 and Figure 9 As shown, the second transmission unit 53 is configured to drive the moving member 40 to reciprocate along the second direction while reciprocating along the first direction X.

Therefore, while the sixth moving structure 522 drives the seventh moving structure 531 and the eighth moving structure 533 to reciprocate along the first direction, under the combined action of the seventh moving structure 531, the fifth swing rod 532, the eighth moving structure 533 and the third elastic member 534, the moving member 40 can move along the second direction while moving along the first direction, so as to reciprocate between the second set position and the second use position.

Figure 6 As shown, the seventh movable structure 531 includes a seventh slider 5312 and a seventh slider 5312 adapted to each other. The seventh slide rail 5311 is arranged along the first direction X and is mounted on the sixth slider 5222. A tenth pivot axis 5321 and a twelfth pivot axis 5341 are pivotally disposed on the seventh slider 5312. The movement of the seventh slider 5312 along the seventh slide rail 5311 drives the fifth swing arm to pivot relative to the seventh slider 5312 about the tenth pivot axis 5321 and the third elastic member 534 to pivot relative to the seventh slider 5312 about the twelfth pivot axis 5341.

[0099] In some other embodiments, the first driving unit 52 and the second transmission unit 53 together constitute a driving module 50 ″ of an embodiment of the present application.

[0103] Therefore, even if the upper part of the laser TV installed on the flip member 30 is in a vertical state and the movable member 40 is close to the top of the laser TV cabinet, the movable member 40 can be moved from the second setting position to the second use position during or before the flip member 30 moves from the first setting position to the first use position to avoid interference of the movable member 40 with the pivoting of the flip member 30, so that the structure of the laser TV cabinet with an opening and closing mechanism is compact.
