[0023] Existing ceiling fan lights include integrated fan blades and lighting components, which are suspended from the ceiling by a rod. To ensure sufficient airflow, the rod is usually designed to be long and fully exposed to the external visual space. This not only affects the overall aesthetics but also makes the overall ceiling height feel oppressive in scenarios where only the lighting function is turned on and the fan function is not used. It also results in poor decorative appeal and spatial adaptability.

[0024] In view of this, this application proposes a height adjustment structure. Figures 1 to 5 These are some embodiments of this application.

[0025] Please see Figures 1 to 3 In some embodiments of this application, the height adjustment structure 1000 includes a mounting base 1, a drive structure 2, a connector 3, and an assembly 4. The drive structure 2 is disposed on the mounting base 1. The connector 3 is drivenly connected to the drive structure 2 so as to be movable relative to the mounting base 1 in the vertical direction. The assembly 4 is movably disposed on the connector 3 and drivenly connected to the drive structure 2 so as to be movable relative to the connector 3 in the vertical direction. The mounting base 1 is used to be fixed to the ceiling, and the assembly 4 is used to be fixedly connected to the electrical device 2000.

[0026] Since the drive structure 2 is connected to the connector 3 and the mounting parts 4 in a transmission manner, the drive structure 2 can not only drive the connector 3 to move relative to the mounting base 1 in the vertical direction, but also drive the mounting parts 4 to move relative to the connector 3 in the vertical direction, so that the distance between the electrical device 2000 and the ceiling in the vertical direction can be adjusted, thereby allowing the height of the electrical device 2000 to be freely adjusted according to the user's needs.

[0027] In conjunction with the above description, in the technical solution of this application, by setting a drive structure 2 on the mounting base 1, and setting a connector 3 and an assembly 4 that are connected to the drive structure 2 in a transmission manner, the drive structure 2 can drive the connector 3 and the assembly 4 to move in a coordinated manner in the vertical direction, so as to realize the flexible adjustment of the suspension height of the electrical device 2000. This structural design can effectively solve the problems of large space occupation, poor visual aesthetics, and inability to adjust the suspension height of the electrical device 2000 according to different usage scenarios caused by the fixed length of the suspension rod in the background art, thereby improving the aesthetics and space adaptability of the suspended electrical equipment.

[0028] If the electrical component 2000 is a fan light assembly, the fan light assembly is an integrated structure of fan blades and lighting components. When the user only needs to use the lighting function of the fan light assembly, the drive structure 2 can drive at least one of the connector 3 and the mounting accessories 4 to move upward, so that the fan light assembly moves upward and closer to the ceiling, reducing the visual space exposed to the outside of the height adjustment structure 1000 and improving the overall aesthetics of the suspended electrical appliance.

[0029] When the fan blade function is needed, the drive structure 2 can drive at least one of the connector 3 and the assembly 4 to move downward, so that the fan light assembly moves downward and away from the ceiling. At this time, the fan light assembly is closer to the user, thereby providing the user with sufficient airflow.

[0030] The movement of the connector 3 and the mounting parts 4 relative to the mounting base 1 causes the height adjustment structure 1000 to have a first state and a second state in the vertical direction.

[0031] like Figure 4 As shown, the height adjustment structure 1000 is in the first state at this time, that is, the height adjustment structure 1000 has the smallest size in the vertical direction.

[0032] like Figure 5 As shown, the height adjustment structure 1000 is in the second state at this time, that is, the height adjustment structure 1000 is at its largest size in the vertical direction.

[0033] It should be noted that there are no restrictions on the transmission method of the drive structure 2, drive connector 3, and assembly 4 in the vertical direction.

[0034] In the first embodiment, the drive structure 2 drives the connector 3 and the assembly 4 in stages, and after the drive structure 2 drives the connector 3 to move relative to the mounting base 1, it then drives the assembly 4 to move relative to the connector 3. In the second embodiment, the drive structure 2 can drive the connector 3 and the assembly 4 to move synchronously.

[0035] Of course, regardless of whether the drive structure 2 adopts any of the drive methods in the first or second embodiment described above, it is necessary to ensure that the moving directions of the connector 3 and the assembly 4 are the same in order to achieve the vertical adjustment of the height adjustment structure 1000.

[0036] Please see Figures 4 to 5 In some embodiments of this application, the drive structure 2 includes an output section 21, which extends along the vertical direction and is rotatably disposed on the mounting base 1; the connector 3 is screwed to the output section 21 and anti-rotationally engaged, so that the connector 3 can move relative to the output section 21 in the vertical direction; in this embodiment, since the connector 3 is restricted from rotation and screwed to the output section 21, the connector 3 can move in the vertical direction when the output section 21 rotates, thereby realizing the vertical dimension adjustment of the height adjustment structure 1000.

[0037] Among them, the vertical movement of the connector 3 relative to the mounting base 1 is the first-level lifting adjustment of the height adjustment structure 1000.

[0038] In one specific embodiment of this application, the output part 21 rotates around its center line, and the center line of the output part 21 extends in the vertical direction; this arrangement enables the output part 21 to drive the connector 3 to move linearly in the vertical direction through the screw connection with the connector 3, thereby realizing the first-level lifting adjustment of the height adjustment structure 1000.

[0039] In the above embodiments, the form of the anti-rotation engagement between the connector 3 and the output part 21 is not limited.

[0040] In one embodiment, the connector 3 can achieve anti-rotation engagement with the output part 21 through a sliding engagement with the mounting base 1 in the vertical direction.

[0041] In another embodiment, the connector 3 can achieve a non-rotational engagement with the output section 21 through a sliding engagement with the mounting part 4 in the vertical direction. In this embodiment, since the mounting part 4 is fixedly connected to the electrical component 2000, its own rotation is constrained; through the limiting effect of the mounting part 4 on the connector 3 in the rotational direction, the connector 3 can only move in the vertical direction and cannot rotate with the output section 21, thereby realizing the first-level lifting adjustment of the height adjustment structure 1000.

[0042] Of course, the assembly 4 can also achieve its own rotation restriction through other structures, such as a telescopic rod that is fixedly connected between the assembly 4 and the mounting base 1 and the ceiling.

[0043] Furthermore, when the assembly 4 restricts the rotation of the connector 3, the connector 3 also needs to move in the vertical direction. Therefore, in some embodiments of this application, one of the assembly 4 and the connector 3 is provided with a first guide groove 5 extending in the vertical direction, and the other is provided with a first locking protrusion 6. At least a portion of the first locking protrusion 6 is located in the first guide groove 5 and can move along the extension direction of the first guide groove 5. That is, through the cooperation between the first guide groove 5 and the first locking protrusion 6, the assembly 4 will not interfere with the movement of the connector 3 in the vertical direction, thereby realizing the first-level lifting adjustment of the height adjustment structure 1000.

[0044] Furthermore, the cooperation between the first locking protrusion 6 and the first guide groove 5 can also restrict the rotation of the connector 3 relative to the output part 21. That is, the groove walls of the first locking protrusion 6 and the first guide groove 5 abut against each other in the rotation direction of the connector 3 to restrict the rotation of the connector 3 relative to the output part 21. Therefore, the first locking protrusion 6 can only move in the up and down direction in the first guide groove 5 to ensure the transmission stability of the height adjustment structure 1000 during adjustment.

[0045] A set of limiting structures is formed by the cooperation of a first protrusion 6 and a first guide groove 5. One or more sets of limiting structures can be set between the connector 3 and the assembly 4; no restrictions are imposed here.

[0046] Specifically, multiple sets of limiting structures are provided between the connector 3 and the assembly 4 to enhance the rotational limiting effect of the assembly 4 on the connector 3 and the stability of the connector 3 when it moves in the vertical direction.

[0047] One of the assembly 4 and the connector 3 is provided with a first guide groove 5 extending in the vertical direction, and the other is provided with a first locking protrusion 6. The first guide groove 5 can be provided on the assembly 4 and the first locking protrusion 6 can be provided on the connector 3; alternatively, the first locking protrusion 6 can be provided on the assembly 4 and the first guide groove 5 can be provided on the connector 3.

[0048] In some embodiments of this application, the height adjustment structure 1000 further includes a transmission member 7, which is movably and adjustably disposed on the output part 21 in the vertical direction and can rotate with the output part 21; the mounting part 4 is threadedly engaged with the transmission member 7; wherein, the vertically and adjustably disposed transmission member 7 can, on the one hand, make the size of the height adjustment structure 1000 smaller when in the first state, and on the other hand, since the connecting part 3 can also move relative to the output part 21 in the vertical direction, the vertically and adjustably disposed transmission member 7 can avoid interfering with the movement of the connecting part 3.

[0049] In this embodiment, the mounting part 4 is threadedly engaged with the transmission member 7 so that when the output part 21 rotates, the mounting part 4 can move in the vertical direction under the drive of the transmission member 7, thereby realizing the movement of the mounting part 4 relative to the connecting member 3, and thus realizing the vertical dimension adjustment of the height adjustment structure 1000.

[0050] The vertical movement of accessory 4 is a two-stage lifting adjustment of the height adjustment structure 1000.

[0051] The fact that the transmission member 7 is movably and adjustablely disposed on the output part 21 in the vertical direction means that the transmission member 7 can move relative to the output part 21 in the vertical direction and can be fixed at any position in its active stroke.

[0052] To achieve adjustable vertical movement of the transmission component 7, in some embodiments of this application, the transmission component 7 is rotatably mounted on the connector 3 so as to be movably and adjustablely mounted on the output portion 21 in the vertical direction. In this embodiment, since the output portion 21 can drive the connector 3 to move vertically when it rotates, and since the output portion 21 and the connector 3 are threadedly fitted, the connector 3 can be fixed at any position on its active stroke. By rotatably mounting the transmission component 7 on the connector 3, the transmission component 7 can be movably and adjustablely mounted on the output portion 21 in the vertical direction. This structural design integrates the support function of the transmission component 7 onto the connector 3, simplifies the structural layout of the height adjustment structure 1000, and improves the compactness and overall integration of the height adjustment structure 1000.

[0053] Furthermore, by rotating the transmission component 7 to the connecting component 3, the first-stage and second-stage lifting adjustments of the height adjustment structure 1000 can be synchronously performed under the drive of a single output unit; this structural arrangement enables more efficient and faster overall height adjustment of the height adjustment structure 1000. To ensure that the movement of the transmission component 7 with the output part 21 and the vertical movement of the connecting component 3 relative to the output part 21 do not interfere with each other, in some embodiments of this application, the connecting component 3 includes a connecting part 31 and a first cylindrical part 32. The connecting part 31 is sleeved on the output part 21 and threadedly engaged with the output part 21. The first cylindrical part 32 is located on the side of the connecting part 31 away from the mounting base 1 in the vertical direction and is fixed to the connecting part 31. The first cylindrical part 32 is hollow. At least a portion of the transmission component 7 is located inside the first cylindrical part 32 and is rotatably connected to the connecting component 3. At least a portion of the output part 21 is located inside the first cylindrical part 32 and engages with the transmission component 7.

[0054] In this embodiment, at least a portion of the transmission member 7 is housed within the first cylindrical portion 32 of the connecting member 3. Its movement trajectory is constrained by the space of the first cylindrical portion 32. This allows the transmission member 7 to move vertically along with the connecting member 3 while avoiding motion interference with other structures of the connecting member 3. Simultaneously, the output portion 21 extends vertically through the connecting portion 31 and forms a threaded engagement with it. The portion of the output portion 21 extending into the first cylindrical portion 32 engages with the transmission member 7, enabling the transmission member 7 to move vertically relative to the output portion 21 and to receive driving force to rotate synchronously with the output portion 21 when it rotates. This structural arrangement significantly improves the mechanical compactness and structural integration of the height adjustment structure 1000, helping to reduce the overall size and optimize space utilization efficiency when the height adjustment structure 1000 is retracted to its first state.

[0055] In some embodiments of this application, the assembly 4 includes a second cylindrical portion 41 and an assembly portion 42. The second cylindrical portion 41 is hollow, and a portion of the transmission member 7 is located inside the second cylindrical portion 41 and threadedly engaged with the second cylindrical portion 41. The assembly portion 42 is fixedly disposed on the side of the second cylindrical portion 41 away from the mounting base 1 in the vertical direction. At least a portion of the second cylindrical portion 41 is located inside the connector 3 and is movably engaged with the connector 3 in the vertical direction.

[0056] In some embodiments of this application, the assembly 4 includes a second cylindrical portion 41 and an assembly portion 42. The second cylindrical portion 41 is hollow, and a portion of the transmission member 7 is located inside the second cylindrical portion 41 and threadedly engaged with the second cylindrical portion 41. The assembly portion 42 is fixedly disposed on the side of the second cylindrical portion 41 away from the mounting base 1 in the vertical direction. At least a portion of the second cylindrical portion 41 is located inside the first cylindrical portion 32 and is movably engaged with the first cylindrical portion 32 in the vertical direction.

[0057] In this embodiment, by making the second cylindrical portion 41 of the assembly 4 hollow, the second cylindrical portion 41 can be embedded between the transmission component 7 and the connecting component 3 when the assembly 4 is assembled with them. The inner wall of the second cylindrical portion 41 is threadedly connected to the transmission component 7, and the outer wall of the second cylindrical portion slides with the connecting component 3 in the vertical direction. This allows the assembly 4 to move up and down with the transmission component 7, while also creating a rotational constraint on the connecting component 3 through the sliding fit between the cylindrical walls, effectively transmitting the anti-rotation effect. This structural design significantly improves the mechanical compactness and structural integration of the height adjustment structure 1000, helping to reduce the overall size when the height adjustment structure 1000 is retracted to its first state, thus optimizing space utilization efficiency.

[0058] In one specific embodiment of this application, the outer wall of the second cylindrical portion slides in a vertical direction with the first cylindrical portion 32.

[0059] The assembly part 42 located below the second cylindrical part 41 is fixedly connected to the electrical component 2000.

[0060] Based on the above embodiments, with the connector 3 configured as a combination of the connector 31 and the first cylindrical part 32, and the assembly 4 configured as a combination of the second cylindrical part 41 and the assembly part 42, when the height adjustment structure 1000 is in the first state, the main bodies of the output part 21 and the second cylindrical part 41 are both located inside the first cylindrical part 32, so that the output part 21 and the second cylindrical part 41 are not exposed to the external visual space, thus improving the overall aesthetics of the height adjustment structure 1000.

[0061] In some embodiments of this application, the connecting portion 31 or the first cylindrical portion 32 is provided with a first groove 81 arranged in an annular shape; the transmission member 7 is provided with a second groove 82 arranged in an annular shape at a position corresponding to the first groove 81, and the second groove 82 and the first groove 81 surround each other to form an assembly groove 8; the height adjustment structure 1000 further includes a limiting member 9, which is disposed in the assembly groove 8 and abuts against the assembly groove 8 in the vertical direction; in this embodiment, by providing the cooperation between the limiting member 9 and the assembly groove 8, the relative movement between the transmission member 7 and the connecting member 3 in the vertical direction can be constrained, preventing the limiting member 9 from disengaging from the connecting member 3, while ensuring the rotational freedom of the transmission member 7 relative to the connecting member 3, so that the kinetic energy of the output portion 21 can be transmitted to the assembly 4 via the transmission member 7, so that the assembly 4 can move relative to the connecting member 3 in the vertical direction.

[0062] In one specific embodiment of this application, a recessed platform is formed on the inner side of the first cylindrical portion 32, and at least a portion of the transmission member 7 rests on the recessed platform to restrict the transmission member 7 from separating downward from the first cylindrical portion 32. A first groove 81 is provided on the connecting portion 31. After the connecting portion 31 is fixed to the first cylindrical portion 32, the connecting portion 31 stops the transmission member 7 above the transmission member 7 to restrict the transmission member 7 from separating upward from the first cylindrical portion 32. The first groove 81 on the connecting portion 31 and the second groove 82 on the transmission member 7 form an assembly groove 8. After the limiting member 9 is placed into the assembly groove 8, the abutment between the limiting member 9 and the groove wall of the assembly groove 8 in the vertical direction can further restrict the transmission member 7 from separating from the connecting member 3 in the vertical direction, and allow the transmission member 7 to rotate freely relative to the connecting member 3, so as to ensure that the kinetic energy of the output portion 21 can be transmitted to the assembly part 4 via the transmission member 7.

[0063] The structure of the transmission component 7 is not limited; it can be arranged in a ring or in an arc shape.

[0064] Furthermore, since the transmission member 7 needs to move relative to the output part 21 in the vertical direction when rotating with the output part 21, in some embodiments of this application, at least one of the transmission member 7 and the output part 21 is provided with a second guide groove 10 extending in the vertical direction, and the other is provided with a second locking protrusion 11. At least a portion of the second locking protrusion 11 is located within the second guide groove 10 and can move along the extension direction of the second guide groove 10. That is, through the cooperation of the second guide groove 10 and the second locking protrusion 11, the transmission member 7 can also move relative to the output part 21 in the vertical direction when rotating with the output part 21, thereby avoiding interference of the transmission member 7 with the vertical movement of the connecting member 3.

[0065] A set of limiting structures can be formed by the cooperation of a second latching protrusion 11 and a second guide groove 10. One or more sets of limiting structures can be set between the output part 21 and the transmission member 7; no restrictions are imposed here.

[0066] Specifically, multiple limiting structures are provided between the output section 21 and the transmission member 7 to ensure the stability of the transmission member 7 when it rotates with the output section 21 and the stability of the transmission member 7 when it moves relative to the output section 21 in the vertical direction.

[0067] At least one of the transmission member 7 and the output part 21 is provided with a second guide groove 10 extending in the vertical direction, and the other is provided with a second locking protrusion 11. It is possible that the transmission member 7 is provided with the second guide groove 10 and the output part 21 is provided with the second locking protrusion 11; it is also possible that the transmission member 7 is provided with the second locking protrusion 11 and the output part 21 is provided with the second guide groove 10.

[0068] In some embodiments of this application, the output part 21 is hollow and has a ring-shaped toothed structure 12 on its inner sidewall; the drive structure 2 further includes a drive part 22 and a gear set 23, the drive part 22 is fixedly disposed on the mounting base 1; the gear set 23 includes a first gear 231 and at least one second gear 232, the first gear 231 is fixedly disposed at the output end of the drive part 22, and the second gear 232 is disposed between the first gear 231 and the toothed structure 12, and meshes with both the first gear 231 and the toothed structure 12; in this embodiment, when the drive part 22 is started, power is transmitted to the toothed structure 12 in sequence through the first gear 231 and the second gear 232, thereby driving the output part 21 to rotate around its centerline, so that the output part 21 can perform the function of adjusting the height adjustment structure 1000 in the vertical direction as an output.

[0069] In this embodiment, at least a portion of the drive unit 22, the first gear 231, and the second gear 232 are disposed inside the output unit 21 to achieve a compact spatial layout. Furthermore, the drive unit 22 can increase the output torque through multi-stage gear transmission, thereby improving the reliability and control accuracy of the vertical adjustment of the height adjustment structure 1000.

[0070] This application also proposes a hoisting electrical appliance, which includes a height adjustment structure 1000 and an electrical component 2000. The electrical component 2000 is fixedly installed on the assembly 4. The height adjustment structure 1000 is as described above. Since this hoisting electrical appliance adopts all the technical solutions of the above embodiments, it has at least the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
