Description
Technical Field
[0001] The invention relates to the technical field of fan lamps, in particular to an improved structure of a ceiling fan lamp. Background Art
[0002] The structure of the existing ceiling fan lamp includes a fan part and a lamp part. The fan part is arranged on the upper part of the lamp part. The fan part includes a motor assembly, blades (also known as fan blades), a chassis, a blade extension and reset mechanism. The blades are arranged on the periphery of the upper surface of the chassis through the blade extension and reset mechanism, and the chassis is driven by the motor assembly; when the ceiling fan is working, the motor assembly drives the chassis to rotate, and the blades move along the blade extension and reset mechanism under the action of centrifugal force so that at least a part of the blades extends (throws out) outside the chassis. When the ceiling fan stops working, the blades are affected by the reset force of the blade extension and reset mechanism and retreat to the edge of the upper surface of the chassis; this traditional ceiling fan lamp is also called a ceiling fan lamp with hidden blades (i.e., fan blades), that is, the blades extend out of and retreat to the chassis, and after the blades retreat, the blades cannot be seen from the bottom of the ceiling fan lamp.
[0003] However, the above-mentioned ceiling fan lamp with hidden blades still has the following shortcomings: (1) When the blades are stored, that is, when the blades are retracted (stored), the blades are arranged in a circle on the edge of the upper surface of the chassis. Due to the circumference of the outer edge of the chassis, when the number of blades is large or the length of the blades is long, the adjacent blades will overlap head to tail. Therefore, in order to avoid the overlapping blades from colliding with each other (offsetting each other) during the retraction process, the blades are made into two sections of high and low, or the blades are made to extend upward from low to high. The process of making the blades into two sections of high and low is relatively difficult. Moreover, when the blades are retracted (stored), the high and low connection positions of the blades are prone to collide with adjacent blades. The blades extend from low to high, which will cause the overall height to be relatively large. In particular, the bottom of this ceiling fan lamp also includes a lamp part. Therefore, this ceiling fan lamp with excessive height is not suitable for use in rooms on some lower floors (such as ordinary commercial buildings). (2) When the blade is extended or retracted, it is achieved by rotating the "axis" at the root of the blade. In other words, the rotation of the entire blade is based on the "axis" as a fulcrum. The blade is easily offset (such as drooping) due to installation differences, which can easily cause the blade to collide with the adjacent blade when it is retracted. Therefore, the requirements for the blade installation process are very high. Summary of the invention
[0004] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide an improved structure of a ceiling fan lamp with a small height and low requirements for blade installation technology.
[0005] The object of the present invention is achieved in that:
[0006] An improved structure of a ceiling fan lamp comprises a fan part and a lamp part, wherein the fan part is arranged on the upper part of the lamp part, the fan part comprises a motor, a rotating disk and blades, the motor drives the rotating disk to rotate, an axial hole is opened in the center of the rotating disk, and the fixed shaft of the motor passes through the axial hole, the fan part also comprises a blade guide rail, the blade guide rail is fixed on the rotating disk, one end of the blade guide rail is close to the axial hole, and the other end extends toward the edge of the rotating disk, a sliding seat is arranged on the blade, and the blade sits on the blade guide rail through the sliding seat, when the motor drives the rotating disk to rotate around the fixed axis, the blade slides outward on the blade guide rail through the sliding seat under the action of centrifugal force, so that at least a part of the blade extends out of the rotating disk; this ceiling fan lamp has an improved structure, comprising a fan part and a lamp part, wherein the fan part comprises a fan part and a lamp part, The fan lamp is provided with a blade guide rail on a rotating disk, one end of the blade guide rail is close to the shaft hole, and the other end extends toward the edge of the rotating disk. The blades sit on the blade guide rail. When the blades are stored, that is, in the retracted (stored) state, each blade extends from the center to the outer edge on the upper surface of the chassis through the blade guide rail, forming a scattering state. Therefore, even if a large number of blades are stored on the chassis, overlapping can still be avoided. Furthermore, since the blades sit on the blade guide rail through a sliding seat, the requirements for the blade installation process are not high, and the blades slide stably on the blade guide rail and are not easy to move. What's more, the ceiling fan lamp with this structure can avoid overlapping of blades, so the overall height can be made smaller, which is especially suitable for use in rooms on lower floors.
[0007] The purpose of the present invention can also be solved by the following technical measures:
[0008] Furthermore, the blade guide is a linear guide, which is detachably mounted on the rotating disk through a fixing member; the linear guide ensures that the blade extends and retracts (contracts) along the radius of the rotating disk (or the radius of the fixed axis). Different from the traditional blade expansion and retraction action by axial rotation, this linear expansion and retraction is relatively stable and smooth.
[0009] Furthermore, a linear slide groove is arranged on the outer side wall of the blade guide rail, and a ball bearing is additionally arranged between the slide seat and the linear slide groove; the ball bearing can reduce the friction between the slide seat and the blade guide rail, so that the blade slides more easily and labor-savingly, and the blade extends and retracts (contracts) more smoothly and with lower noise.
[0010] Furthermore, the fan part includes more than two blades, and the blade guide rail is provided on the rotating disk corresponding to each blade; the number of blades can be 3, 4, 5 or even more to meet the needs of different usage scenarios.
[0011] Furthermore, a synchronous disk is also included, and the synchronous disk is arranged on the fan part and adjacent to the rotating disk. A guide hole is opened on the synchronous disk corresponding to each blade. The guide hole is an arc hole, one end of the arc hole is close to the center of the synchronous disk, and the other end extends toward the edge of the synchronous disk. A limited slot is opened on the blade guide rail along its length extension direction. A guide column extends from the blade or the slide seat, and the guide column passes through the limited slot and extends into the guide hole. When the blade extends, the blade drives the guide column to move in the limited slot, and the guide column also moves in the guide hole, that is, the guide column will push the synchronous disk to rotate, and then the synchronous disk keeps all blades moving synchronously, so that the blade is more stable.
[0012] Furthermore, a center hole is opened in the center of the synchronous disk, and the fixed shaft of the motor passes through the center hole, so that the synchronous disk is suspended on the fixed shaft and rotates around the fixed shaft; the synchronous disk and the rotating disk both rotate around the fixed shaft, and the rotation of the synchronous disk is asynchronous with the rotation of the rotating disk.
[0013] Furthermore, the synchronization disk is arranged below the rotating disk, which is convenient for setting a reset member to realize the blade reset and retraction function (blade retraction).
[0014] Furthermore, a reset member is included, wherein two ends of the reset member are respectively connected to the rotating disk and the synchronous disk. The motor drives the rotating disk to rotate, and the blades extend. The rotation speed difference between the rotating disk and the synchronous disk during rotation compresses or stretches the reset member. After the motor stops, the reset member resets, driving the synchronous disk to rotate in the opposite direction. The synchronous disk pushes the guide column to move in the limit slot through the guide hole, thereby realizing the synchronous retraction of the blades (retracting the rotating disk), that is, the blades are hidden.
[0015] Furthermore, the reset member is a pot ring spring, which is sleeved on the fixed shaft and located between the rotating disk and the synchronous disk. The pot ring spring is small in size, easy to install, easy to obtain, and low in cost. The length of the guide hole also limits the elastic force range of the pot ring spring, thereby avoiding excessive stretching or compression failure of the pot ring spring.
[0016] The beneficial effects of the present invention are as follows:
[0017] (1) This type of ceiling fan light has a blade guide rail arranged on the rotating disk, one end of the blade guide rail is close to the shaft hole, and the other end extends toward the edge of the rotating disk. The blades are seated on the blade guide rail. When the blades are stored, that is, when the blades are retracted (stored), each blade extends from the center to the outer edge on the upper surface of the chassis through the blade guide rail, forming a scattered state. Therefore, even when a large number of blades are stored on the chassis, overlapping can still be avoided. In addition, since the blades are seated on the blade guide rail through a sliding seat, the requirements for the blade installation process are not high. Moreover, the blades slide stably on the blade guide rail and are not easily displaced. Moreover, since this structure of the ceiling fan light avoids blade overlap, the overall height can be made smaller, which is particularly suitable for use in rooms on lower floors.
[0018] (2) Secondly, the linear guide ensures that the blades extend and retract (contract) along the radius of the rotating disk (or the radius of the fixed shaft). Unlike the traditional blade extension and retraction action by shaft rotation, this linear extension and retraction is relatively stable and smooth.
[0019] (3) In addition, when the blades are extended, the blades drive the guide column to move in the limit slot, and the guide column also moves in the guide hole, that is, the guide column will push the synchronous disk to rotate, and then the synchronous disk will keep all the blades moving synchronously, so that the blades are extended more stably; after the motor stops, the reset part resets, driving the synchronous disk to rotate in the opposite direction, and the synchronous disk pushes the guide column to move in the limit slot through the guide hole, thereby realizing the synchronous retraction of the blades (retracting the rotating disk), that is, the blades are hidden.
[0020] (4) The reset member is a pot ring spring, which is small in size, easy to install, easy to obtain, and low in cost. The length of the guide hole also limits the elastic force range of the pot ring spring, avoiding excessive stretching or compression failure of the pot ring spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] like Figures 1 to 7 As shown, an improved structure of a ceiling fan lamp includes a fan part 1 and a lamp part 2, wherein the fan part 1 is arranged on the upper part of the lamp part 2, and the fan part 1 includes a motor 3, a blade collecting cover 4, blades 5, blade guides 6 and a synchronous disk 7. The motor 3 is an outer rotor motor 3, and the blade collecting cover 4 includes a top cover 41, an annular side wall 42 and a rotating disk 43. The annular side wall 42 is arranged around the upper surface of the rotating disk 43, and an axial hole 44 is opened at the center of the rotating disk 43. A blade inlet and outlet hole 40 is opened on the annular side wall 42, and the shape of the blade inlet and outlet hole 40 is adapted to the blade 5. The top cover 41 is fixed to the upper opening of the annular side wall 42, and a through hole 45 is opened in the center of the top cover 41. The housing of the motor 3 is fixed to the top cover 41 by bolts, and the blades 5 and the blade guides 6 are arranged in a cavity surrounded by the rotating disk 43, the annular side wall 42 and the top cover 41.
[0030] The blade guide rail 6 is a linear guide rail, which is fixed on the rotating disk 43 by screws, and a limiting through groove 61 is provided on the blade guide rail 6 along its length extension direction. One end of the blade guide rail 6 is close to the shaft hole 44, and the other end extends toward the edge direction of the rotating disk 43, that is, the blade guide rail 6 is arranged along the radial direction of the rotating disk 43, and a linear slide groove 62 is arranged on the outer side wall of the blade guide rail 6, and a slide seat 51 is arranged on the blade 5, and a guide column 50 extends downward from the bottom surface of the slide seat 51, and the blade 5 sits on the blade guide rail 6 through the slide seat 51, and the guide column 50 passes through the limiting through groove 61, and a ball 52 is also arranged between the slide seat 51 and the linear slide groove 62, and the guide column 50 passes through the limiting through groove 61.
[0031] In this embodiment, there are four blade guide rails 6 and four blades 5. The fixed axis of the motor 3 passes through the through hole 45 and the shaft hole 44 downward in sequence. Each blade 5 is set on a blade guide rail 6 through a slide seat 51. The four blade guide rails 6 are arranged in a ring with equal spacing around the fixed axis 30 of the motor 3.
[0032] The synchronous disk 7 is arranged below the rotating disk 43, and a groove 71 is arranged at the center of the synchronous disk 7, and a center hole 72 is opened in the groove 71, and the fixed shaft 30 passes through the center hole 72. A fixed block 31 is arranged on the fixed shaft 30, and the synchronous disk 7 is placed on the fixed block 31, that is, it is hung on the fixed shaft 30 and rotates around the fixed shaft 30. A reset member 8 is arranged in the groove 71, and the reset member 8 is a pot ring spring. The reset member 8 is sleeved on the fixed shaft 30, and the two ends of the reset member 8 are respectively connected to the rotating disk 43 and the synchronous disk 7.
[0033] A guide hole 70 is opened on the synchronous disk 7 corresponding to each blade 5. The guide hole 70 is an arc-shaped hole. The guide holes 70 are arranged in a ring with equal intervals around the fixed shaft 30 as the center. One end of the guide hole 70 is close to the center of the synchronous disk 7, and the other end extends toward the edge of the synchronous disk 7. The guide column 50 extends downward into the corresponding guide hole 70.
[0034] The fixed shaft 30 passes through the central hole 72 and is connected to the lamp part 2 via a bearing.
[0035] The motor 3 drives the top cover 41 to rotate counterclockwise around the fixed axis 30, thereby driving the blade collection cover 4 to rotate counterclockwise as a whole, that is, the motor 3 drives the rotating disk 43 to rotate counterclockwise, and the blade 5 and the blade guide 6 also rotate counterclockwise synchronously with the rotating disk 43. Under the action of centrifugal force, the blade 5 slides along the blade guide 6 toward the blade inlet and outlet hole 40, and at least a part of the blade 5 extends out of the rotating disk 43 through the blade inlet and outlet hole 40. The part of the blade 5 extending out of the rotating disk 43 drives air flow, thereby realizing the fan function. When the blade 5 moves on the blade guide rail 6 through the slide 51, the guide column 50 of the slide 51 moves in the limiting groove 61. At the same time, the guide column 50 also moves in the guide hole 70 of the synchronous disk 7. Since the guide hole 70 and the limiting groove 61 only partially overlap in the vertical direction, the guide column 50 of the slide 51 drives the guide column 50 to move in the limiting groove 61. The guide column 50 pushes the synchronous disk 7 to rotate around the fixed axis 30 through the guide hole 70. The limiting groove 61 and the guide hole 70 are different in length. Therefore, there is a rotation speed difference between the rotating disk 43 and the synchronous disk 7, that is, the pot ring spring is compressed when the rotating disk 43 and the synchronous disk 7 rotate.
[0036] When the motor 3 stops working and the centrifugal force of the rotating disk 43 is less than the elastic force of the pot ring spring, the pot ring spring pushes the step disk to rotate clockwise, and the guide hole 70 pushes the guide column 50 to move, that is, the guide column 50 pushes the slide seat 51 to slide inward on the blade guide rail 6, that is, the blade 5 slides inward on the blade guide rail 6, thereby achieving the purpose of retreating the blade 5 into the blade collection cover 4, that is, realizing the function of hiding the blade 5.
