For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection, a contact connection, or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0036] A flipping mechanism 1, such as Figures 1-12 As shown, the device includes: a linkage assembly 10, a blocking member 20, and an auxiliary member 30. The linkage assembly 10 connects a movable member 50 and a fixed member 40, allowing the movable member 50 to rotate relative to the fixed member 40 between a folded position and an open position. The movable member 50 has a receiving groove 51. The auxiliary member 30 is hinged to the movable member 50, allowing it to rotate within the receiving groove 51. The blocking member 20 connects the linkage assembly 10 and the auxiliary member 30, enabling the linkage assembly 10 to drive the blocking member 20 and the auxiliary member 30 to move relative to the movable member 50. Thus, when the movable part 50 is in the folded position, the linkage assembly 10, the auxiliary part 30, and the shielding part 20 are folded together, and the shielding part 20 and the auxiliary part 30 are housed in the receiving groove 51, making the structure of the flipping mechanism 1 more compact; when the movable part 50 is in the open position, the linkage assembly 10 and the shielding part 20 are unfolded, and at least part of the linkage assembly 10 and the shielding part 20 can shield the receiving groove 51, and the shielding part 20 is located above the auxiliary part 30, which helps to prevent foreign objects from falling into the receiving groove 51, thereby reducing the risk of the flipping mechanism 11 getting stuck or even unable to be used normally due to foreign objects falling in.
[0037] In some embodiments, such as Figure 7 , Figure 8 , such as 10 and Figure 11 As shown, the linkage assembly 10 includes a first linkage 11, one end of which is hinged to a fixed member 40, and the other end of which is hinged to a movable member 50. An auxiliary member 30 has a first end 31 and a second end 32 disposed opposite to each other, and a blocking member 20 has a third end 21 and a fourth end 22 disposed opposite to each other. The first end 31 is hinged to the movable member 50, the second end 32 is hinged to the third end 21, and the fourth end 22 is hinged to the first linkage 11. When the movable member 50 is in the folded position, the first linkage 11 and the auxiliary member 30 fold and approach the blocking member 20, and along the rotation axis of the auxiliary member 30, the projection of the auxiliary member 30 intersects and overlaps with the projection of the blocking member 20. That is, the first linkage 11 is adapted to rotate relative to the movable member 50, and the auxiliary member 30 is also adapted to rotate relative to the movable member 50. The blocking member 20 is connected between the first linkage 11 and the auxiliary member 30 to facilitate movement relative to the movable member 50.
[0038] Specifically, such as Figures 7-9 As shown, when the movable part 50 is in the folded position, the first connecting rod 11 and the auxiliary part 30 fold and abut against the blocking part 20, and the auxiliary part 30 and the blocking part 20 are accommodated in the receiving groove 51. Further, along the rotation axis direction of the auxiliary part 30, i.e. along... Figure 8 and Figure 9 In the direction shown, the projection of the auxiliary member 30 intersects and overlaps with the projection of the shielding member 20, making the auxiliary member 30 and the shielding member 20 more compact, which in turn helps to reduce the depth of the receiving groove 51.
[0039] like Figures 10-12 As shown, when the movable member 50 is in the open position, the first connecting rod 11 and the blocking member 20 unfold to cover the receiving groove 51. That is, at least a portion of the first connecting rod 11 and the blocking member 20 are arranged sequentially in the receiving groove 51, and the upper surface of at least a portion of the first connecting rod 11 and the upper surface of the blocking member 20 are flush with or nearly flush with the upper surface of the movable member 50, which helps to prevent foreign objects from falling into the receiving groove 51.
[0040] It is worth mentioning that, such as Figure 10 and Figure 11 As shown, in this embodiment, when the movable member 50 is in the open position, only at least a portion of the first connecting rod 11 and the blocking member 20 are located at the opening of the receiving groove 51 to block the receiving groove 51, while the auxiliary member 30 is located inside the receiving groove 51 below the blocking member 20. That is to say, the opening of the receiving groove 51 is blocked by a two-section structure. Compared with a three-section or more-section blocking structure, the two-section blocking structure in this embodiment helps to make the appearance of the flipping mechanism 1 more concise and beautiful.
[0041] In some embodiments, such as Figure 4 , Figure 8 and Figure 9 As shown, the auxiliary member 30 has a clearance area 33, which is located between the first end 31 and the second end 32. When the movable member 50 is in the open position, the blocking member 20 is located above the auxiliary member 30, and part of the blocking member 20 can block the clearance area 33. When the movable member 50 moves from the open position to the folded position, the third end 21 of the blocking member 20 can pass through the clearance area 33, so that the auxiliary member 30 folds and closes to the blocking member 20, and along the rotation axis direction of the auxiliary member 30, the projection of the auxiliary member 30 and the projection of the blocking member 20 intersect and overlap.
[0042] Specifically, such as Figure 11 and Figure 12 As shown, when the movable member 50 is in the open position, a portion of the third end 21 of the blocking member 20 is located above the auxiliary member 30 to block the opening of the receiving groove 51, and the auxiliary member 30 is hidden within the receiving groove 51 below the blocking member 20. Further, as... Figure 9As shown, when the movable part 50 moves from the open position to the folded position, the auxiliary part 30 moves around its first end 31 along the following path... Figure 9 The auxiliary member 30 rotates counterclockwise as shown, meaning it rotates from the opening near the receiving groove 51 toward the interior of the receiving groove 51; simultaneously, a portion of the third end 21 of the blocking member 20 passes through the clearance area 33 between the first end 31 and the second end 32 of the auxiliary member 30, thereby allowing the blocking member 20 to rotate toward the interior of the receiving groove 51. Figure 9 As shown, the lower right movement means that the blocking member 20 moves from the opening of the receiving groove 51 toward the bottom of the receiving groove 51. Finally, along the rotation axis direction of the auxiliary member 30, the projection of the auxiliary member 30 intersects and overlaps with the projection of the blocking member 20.
[0043] This should be understandable, such as Figure 9 As shown, when the movable part 50 is in the folded position, along the rotation axis of the auxiliary part 30, the projection of the auxiliary part 30 and the projection of the blocking part 20 intersect and overlap, so that the space occupied by the auxiliary part 30 along the length direction falls into the space occupied by the blocking part 20 along the length direction. This helps to shorten the overall length of the space occupied by the auxiliary part 30 and the blocking part 20 after they are folded together. In other words, it helps to reduce the length of the required receiving slot 51, thereby reducing the space occupied by the flipping mechanism 1 on the table device 2, making the flipping mechanism 1 suitable for a smaller table device 2. Wherein, the length direction is as follows: Figure 9 The horizontal direction is shown.
[0044] It is worth mentioning that, among the related technologies, such as Figure 3 As shown, the flipping mechanism 1 does not have an auxiliary component 30. One end of the blocking component 20 is hinged to the first connecting rod 11, and the other end of the blocking component 20 is adapted to move along the slide groove on the movable component 50. That is, the movement trajectory of the blocking component 20 is restricted by the cooperation of the first connecting rod 11 and the slide groove, which increases the depth and length of the required receiving groove 51. In this embodiment, when the movable component 50 is in the folded position, the projection of the auxiliary component 30 and the projection of the blocking component 20 intersect and overlap along the rotation axis direction of the auxiliary component 30. This not only helps to reduce the depth of the required receiving groove 51, but also helps to reduce the length of the required receiving groove 51, thus making it suitable for thinner and smaller tabletop devices 2.
[0045] In some embodiments, such as Figure 4 As shown, the auxiliary member 30 includes a connecting arm 35 and two extending arms 34. The two extending arms 34 are respectively connected to opposite ends of the connecting arm 35 to form a clearance area 33 between the connecting arm 35 and the extending arms 34. A second hinge structure 341 is provided on the end of the extending arm 34 away from the connecting arm 35, so as to be hinged to the third end 21 of the blocking member 20. That is, at least a portion of the blocking member 20 is located between the two extending arms 34 of the auxiliary member 30 and is adapted to extend into the clearance area 33.
[0046] Furthermore, the blocking member 20 is connected to the second hinge structure 341 on the two extension arms 34. When the blocking member 20 moves under the drive of the first link 11, it can apply torque to the extension arms 34 to drive the auxiliary member 30 to rotate relative to the movable member 50. It should be understood that by bearing the torque on the two extension arms 34, the force on the auxiliary member 30 is more balanced, thereby making the rotational movement of the auxiliary member 30 smoother and extending the service life of the auxiliary member 30. This is beneficial to improving the operability and structural reliability of the flipping mechanism 1.
[0047] In some embodiments, such as Figure 4 As shown, the connecting arm 35 has a first hinge structure 351, which allows it to be hinged to the movable member 50. In at least one embodiment, the first hinge structure 351 is implemented as a hinge hole in the connecting arm 35, so as to make the structure of the auxiliary member 30 simpler and more compact, thereby reducing the size of the auxiliary member 30 and improving the manufacturability of the auxiliary member 30.
[0048] In some embodiments, such as Figure 5 and Figure 9 As shown, the shielding member 20 includes a main section 24 and a first branch section 23 connected in sequence. A third hinge structure 26 is provided between the main section 24 and the first branch section 23, so as to be hinged with the second hinge structure 341 of the auxiliary member 30. Specifically, as... Figure 9 As shown, when the movable member 50 moves from the open position to the folded position, the first segment 23 passes through the clearance area 33, allowing the auxiliary member 30 to fold and approach the blocking member 20, thereby allowing the auxiliary member 30 and the blocking member 20 to be accommodated in the receiving groove 51. Further, as... Figure 12 As shown, when the movable part 50 is in the open position, the first branch 23 of the blocking part 20 is located above the clearance area 33 of the auxiliary part 30, thereby blocking the clearance area 33 of the auxiliary part 30, that is, blocking the receiving groove 51, which helps to prevent foreign objects from falling into the receiving groove 51.
[0049] In some embodiments, such as Figure 4 and Figure 5 As shown, the rotation axis is defined between the third hinge structure 26 and the second hinge structure 341. The distance from the end of the first branch 23 away from the main branch 24 to the rotation axis is denoted as L1, and the distance between the connecting arm 35 and the rotation axis is denoted as L2. Wherein, L1 < L2, so that the first branch 23 can pass smoothly through the clearance area 33, which helps to avoid interference between the shielding member 20 and the auxiliary member 30.
[0050] In some embodiments, such as Figure 6 , Figure 9 and Figure 12As shown, the first link 11 includes a first fixed end 111 and a first movable end 112 disposed opposite to each other, wherein the first fixed end 111 is hinged to the fixed member 40, and the first movable end 112 is hinged to the movable member 50. Further, the first link 11 from the first fixed end 111 to the first movable end 112 includes a connecting section 113, a blocking section 114, and a receiving section 115 disposed sequentially. The connecting section 113 and the receiving section 115 extend to opposite sides of the blocking section 114. The connecting section 113 is hinged to the fixed member 40, and the receiving section 115 is hinged to the movable member 50, so that when the movable member 50 is in the open position, the movable member 50 is disposed at an angle to the fixed member 40; when the movable member 50 is in the folded position, the movable member 50 is disposed parallel to or nearly parallel to the fixed member 40. The fourth end 22 of the blocking member 20 is hinged to the receiving section 115, thereby the first link 11 can drive the blocking member 20 to move relative to the movable member 50.
[0051] Furthermore, the receiving section 115 has a receiving groove 1151 with an opening facing the blocking member 20. Specifically, when the movable member 50 is in the open position, such as Figures 10-12 As shown, the blocking section 114 shields the receiving groove 51; the connecting section 113 extends from the blocking section 114 toward the fixing member 40 and is hinged to the fixing member 40; the receiving section 115 is housed within the receiving groove 51, and a portion of the blocking member 20 is located above the receiving section 115, thus shielding the receiving section 115. It should be understood that the portion of the blocking member 20 is located at the opening of the receiving groove 1151, such that the upper surface of the blocking member 20 is flush with or nearly flush with the upper surface of the blocking section 114 of the first connecting rod 11, thereby shielding the receiving groove 51 and reducing the gap between the blocking section 114 of the first connecting rod 11 and the blocking member 20.
[0052] When the movable part 50 is in the folded position, such as Figures 7-9 As shown, the first link 11 and the blocking member 20 are folded together, and a portion of the blocking member 20 is accommodated in the receiving groove 1151. That is, during the process of the movable member 50 flipping from the open position to the folded position, a portion of the blocking member 20 is adapted to move from the opening of the receiving groove 1151 into the receiving groove 1151, and at the same time, the blocking member 20 moves from the opening of the receiving groove 51 to the bottom of the receiving groove 51, until the movable member 50 is in the folded position, at which point a portion of the blocking member 20 is accommodated at the bottom of the receiving groove 1151. The blocking member 20 is accommodated in the receiving groove 51, making the structure between the first link 11, the blocking member 20 and the movable member 50 more compact, which is conducive to the movable member 50 moving closer to the fixed member 40 and reducing the distance between the movable member 50 and the fixed member 40.
[0053] In some embodiments, such as Figure 6As shown, the receiving section 115 includes a main body 1152 and a connecting portion 1154. The main body 1152 extends and bends from the blocking section 114 to form a receiving groove 1151. The end of the main body 1152 away from the blocking section 114 has a fifth hinge structure 1153, allowing it to be hinged to the movable member 50. Furthermore, the connecting portion 1154 is connected to the end of the main body 1152 away from the blocking section 114 and extends toward the blocking section 114. The end of the connecting portion 1154 away from the main body 1152 has a sixth hinge structure 1155. Further, as... Figure 5 As shown, the shielding member 20 includes a main section 24 and a second branch section 25 connected in sequence. A fourth hinge structure 27 is provided between the main section 24 and the second branch section 25, which can be hinged to the sixth hinge structure 1155. When the movable member 50 is in the open position, the second branch section 25 can shield the receiving groove 1151. When the movable member 50 is in the folded position, the second branch section 25 is accommodated in the receiving groove 1151.
[0054] This should be understandable, such as Figure 6 As shown, the main body 1152 extends downward from the blocking section 114 toward the blocking member 20, and the connecting portion 1154 extends toward the blocking section 114, so that the sixth hinge structure 1155 is provided close to the opening of the receiving groove 1151, so that when the movable member 50 is in the open position, as Figure 12 As shown, the receiving section 115 is housed in the receiving groove 51, and the second branch 25 of the blocking member 20 can block the opening of the receiving groove 1151, that is, block the receiving groove 51 to reduce the gap between the blocking section 114 of the first connecting rod 11 and the blocking member 20. When the movable member 50 is in the folded position, as Figure 9 As shown, the second segment 25 of the shield 20 is housed in the receiving groove 1151, so that it can approach the connecting part 1154. At the same time, at least a portion of the shield 20 and the receiving segment 115 are housed in the receiving groove 51, which makes it easier for the movable part 50 to be closer to the fixed part 40.
[0055] In some embodiments, such as Figure 5 and Figure 12 As shown, the main section 24 of the shield 20 is provided with an abutment surface 241. When the movable member 50 is in the open position, the abutment surface 241 abuts against the connecting part 1154 of the receiving section 115 of the first link 11, thereby improving the connection stability between the shield 20 and the first link 11. The connecting part 1154 can support the shield 20, which helps to reduce the risk of bending or damage to the shield 20 when it is subjected to pressure.
[0056] In some embodiments, such as Figure 7 , Figure 8 , Figure 10 and Figure 11As shown, the linkage assembly 10 also includes a second linkage 12. The second linkage 12 includes a second fixed end 121 and a second movable end 122 disposed opposite to each other. The second fixed end 121 is hinged to the fixing member 40 and spaced apart from the first fixed end 111 of the first linkage 11. The second movable end 122 is hinged to the movable member 50 and spaced apart from the first movable end 112 of the first linkage 11. Figure 7 and Figure 8 As shown, when the movable part 50 is in the folded position, the first link 11 and the second link 12 can be brought side by side so that the movable part 50 is close to the fixed part 40; as Figure 10 and Figure 11 As shown, when the movable part 50 is in the open position, the second movable end 122 of the second link 12 abuts against the lower part of the blocking section 114 of the first link 11, thereby supporting and positioning the movable part 50 through the cooperation of the first link 11 and the second link 12.
[0057] A tabletop device 2, such as Figure 1 and Figure 2 As shown, the device includes a tabletop 60 and at least two flipping mechanisms 1 as described above. Specifically, the tabletop 60 has opposing first side portions 61 and second side portions 62, wherein a movable member 50 of one flipping mechanism 1 is fixed to the first side portion 61 of the tabletop 60, and a movable member 50 of the other flipping mechanism 1 is fixed to the second side portion 62 of the tabletop 60. Further, the fixing member 40 of the flipping mechanism 1 is adapted to be fixed at the installation location, so that the tabletop 60 is folded or unfolded relative to the installation location. It is worth noting that the installation location includes, but is not limited to, the backrest of a car seat; this application does not specifically limit this.
[0058] It should be understood that the upper surface of the movable part 50 is flush with or nearly flush with the upper surface of the tabletop 60. When the tabletop 60 is opened at the opposite mounting point, at least part of the linkage assembly 10 of the flipping mechanism 1 and the blocking part 20 can cover the receiving groove 51 of the movable part 50, so that the working surface of the tabletop device 2 is flatter and more aesthetically pleasing, and it is also beneficial to prevent foreign objects from falling into the receiving groove 51, thereby reducing the risk that the tabletop device 2 may become stuck or even unable to be used normally due to foreign objects falling in.
[0059] In at least one embodiment, such as Figure 2 As shown, the tabletop 60 includes a housing 63 and a mounting bracket 64 housed within the housing 63. The movable part 50 of the flipping mechanism 1 is fixed to the mounting bracket 64, which helps to improve the reliability of the connection between the flipping mechanism 1 and the tabletop 60.
