DETAILED DESCRIPTION

[0033] The embodiments of the utility model will be described below in detail with reference to the drawings.

[0034] As Figures 1-10 The utility model discloses an energy-absorbing hanging mechanism, including hanging ball 1 and the hanging rod 2 for receiving ceiling fan hanging in hanging ball 1, the upper portion of hanging rod 2 is equipped with the energy-absorbing assembly 3 for the energy-absorbing of axial vibration that ceiling fan is transferred to the upper portion of hanging rod 2, energy-absorbing assembly 3 is also configured to reduce the driving energy of the circumferential rotation or circumferential rotation tendency that hanging rod 2 suffers, and the upper portion of energy-absorbing assembly 3 is elastically connected with the upper portion of hanging rod 2, and the upper portion of energy-absorbing assembly 3 is fixedly connected with hanging ball 1.

[0035] The traditional ceiling fan is generally installed on the ceiling by a hanging bracket, and the ceiling fan is installed by setting a hanging ball 1 at the top of the hanging rod 2 to cooperate with the hanging bracket. During use, the ceiling fan will vibrate, and the vibration will be conducted to the ceiling through the hanging rod 2. The noise generated by the vibration will be spread and amplified on the ceiling, affecting the user experience. On the other hand, long-term use may cause the hanging bracket to loosen and fall off, posing a safety hazard. In addition, the hanging rod 2 and the hanging ball 1 are generally connected by a pin shaft. Due to the vibration of the motor, the position may also loosen and produce abnormal noise.

[0036] The above-mentioned defects are all caused by the vibration of the hanging rod 2. The hanging rod 2 is vertically arranged, and after the vibration energy is transmitted to the hanging rod 2, it will be decomposed into the force in the vertical direction of the hanging rod 2 and the force driving the rotation of the hanging rod 2. When the ceiling fan starts or stops, the hanging rod 2 will rotate or have a tendency to rotate. Therefore, in the present application, by setting the energy-absorbing assembly 3, the axial energy of the hanging rod 2 can be absorbed to reduce the transmission of vibration to the ceiling by the hanging rod 2, and to reduce the driving energy of the circumferential rotation or circumferential rotation tendency that the hanging rod 2 suffers, preventing the vibration noise from being spread and amplified on the ceiling, and preventing the hanging bracket from loosening due to the vibration of the hanging rod 2, causing a safety hazard.

[0037] In addition, by setting the energy-absorbing assembly 3, the requirement for the machining precision of the motor in the ceiling fan can be reduced, effectively reducing the production cost of the motor. The vibration generated by the ordinary motor can be reduced by the energy-absorbing assembly 3, preventing the vibration noise from being transmitted through the hanging rod 2 and being spread and amplified on the ceiling.

[0038] As Figures 2 to 6As shown, as a further embodiment, the upper part of the suspension rod 2 has a through hole 20 extending through it. A horizontal pin 21 for suspending the suspension rod 2 passes through the through hole 20. The hanging ball 1 has a hanging groove 10 for supporting the left and right ends of the horizontal pin 21. The suspension rod 2 is connected to the energy absorption component 3 through the horizontal pin 21. In this embodiment, after the ceiling fan is installed, the suspension rod 2 is suspended on the hanging groove 10 by the horizontal pin 21 and connected to the energy absorption component 3. It should be noted that the through hole 20 is a strip-shaped hole arranged along the length of the suspension rod 2. When the horizontal pin 21 is subjected to force, it can move up and down in the through hole 20. Since the horizontal pin 21 is connected to the energy absorption component 3, the vibration can be transmitted to the energy absorption component 3 for release through the horizontal pin 21. In addition, there is a gap between the two ends of the horizontal pin 21 at the hanging groove 10, which can rotate at a certain angle. Since the horizontal pin 21 is also connected to the energy absorption component 3, the energy in the circumferential direction of the suspension rod 2 can also be released.

[0039] like Figures 2 to 6 As shown, as a further embodiment, the energy-absorbing assembly 3 includes a bushing 30 disposed in the upper part of the boom 2 and movably connected to the boom 2, and an elastic member 31 disposed in the bushing 30 that can be torsional and compressively deformed. It also includes a support sleeve 32 disposed on the top of the elastic member 31 and fixedly connected to the elastic member 31. The top of the elastic member 31 is fixedly connected to the bottom of the bushing 30, the upper part of the bushing 30 is fixedly connected to the hanging ball 1, the outer wall of the support sleeve 32 is slidably fitted with the bushing 30, and the bushing 30 is provided with an movable hole 33 for the horizontal pin 21 to pass through. The top of the support sleeve 32 is connected to the horizontal pin 21 so that the boom 2 transmits the driving energy of the circumferential rotation or circumferential rotation tendency of the boom 2 to the support sleeve 32 and the elastic member 31 for reduction through the horizontal pin 21.

[0040] In the embodiment, when the energy-absorbing assembly 3 is installed with the hanger 2 and the hanger ball 1, the elastic member 31 is fixed with the supporting sleeve 32 in advance, for example, by welding, and then the elastic member 31 is connected with the bottom of the bushing 30, and then is sleeved into the hanger 2, so that the movable hole 33 is aligned with the through hole 20, and then the cross pin 21 is inserted into the hanger 2 and the bushing 30, and then the hanger 2 is inserted into the upper part of the hanger ball 1, and the cross pin 21 is clamped in the hanger groove 10, and the installation is completed. After the hanger 2 is installed with the motor blades and other parts of the hanger fan, under the action of gravity, the two ends of the cross pin 21 are in contact with the bottom of the hanger groove 10, and the elastic member 31 is in a compressed state, and the hanger groove 10 can support the cross pin 21. It should be noted that the movable hole 33 is also a strip-shaped hole, the cross pin 21 can move up and down in the movable hole 33, and the diameter of the cross pin 21 is smaller than the width of the movable hole 33, so that there is a gap when the cross pin 21 is inserted into the movable hole 33, so that the cross pin 21 has a space to twist the elastic member 31 when it is stressed, thereby releasing the circumferential energy of the hanger 2. In addition, since the outer wall of the supporting sleeve 32 is in sliding fit with the bushing 30, there is friction between the two, and since the elastic member 31 is fixedly connected with the supporting sleeve 32, the supporting sleeve 32 can also reduce energy and thus play a role in vibration reduction.

[0041] As shown in Figure 3 , Figures 7 to 9 , in the embodiment, the elastic member 31 is a spring, the upper end of the spring is fixedly connected with the bottom of the supporting sleeve 32, the bottom of the bushing 30 is formed with a connecting portion 34, and the lower end of the spring is fixedly connected with the connecting portion 34. The lower end of the spring extends inwardly to form a torsion arm 35, and the connecting portion 34 has a clamping groove 36 clamped with the torsion arm 35. After the upper end of the spring is fixedly connected with the supporting sleeve 32, the torsion arm 35 at the lower end of the spring is clamped into the clamping groove 36, so that the spring does not rotate in the bushing 30 when the entire spring is twisted. In the present application, the torsion arm 35 and the clamping groove 36 are in interference fit, so that they can be clamped tightly to prevent loosening and produce abnormal noise. In addition, it should be noted that the upper end of the spring can be fixed with the supporting sleeve 32 by welding, or can be connected and fixed in the same way as the lower end of the spring and the connecting portion 34.

[0042] As shown in Figure 7 , Figure 8 , as a further scheme of the embodiment, the diameter of the spring gradually increases from the middle part to the two ends, which can facilitate the twisting of the spring and quickly absorb energy and reduce vibration.

[0043] As shown in Figure 2 , Figure 7As shown, as a further embodiment, a rubber ring 37 is fitted on the upper outer periphery of the support sleeve 32, and the outer diameter of the rubber ring 37 is larger than the outer diameter of the support sleeve 32. The rubber ring 37 slides in contact with the inner wall of the bushing 30. By setting the rubber ring 37, the rubber ring 37 can cooperate with the inner wall of the bushing 30, which can prevent the support sleeve 32 from directly contacting the inner wall of the bushing 30 and producing abnormal noise. It can also work with the spring to reduce the vibration generated by the suspension rod 2.

[0044] like Figure 3 , Figure 7 As shown, as a further solution of this embodiment, in order to enable the horizontal pin 21 to twist the support sleeve 32, the upper end of the support sleeve 32 is provided with an abutment groove 38. The bottom of the horizontal pin 21 flexibly abuts against the abutment groove 38 and restricts the lower part of the horizontal pin 21 within the abutment groove 38. By setting the abutment groove 38 to abut against the horizontal pin 21, the suspension rod 2 can act on the support sleeve 32 through the horizontal pin 21. In addition, the two are in flexible contact, which avoids abnormal noise. For example, a rubber sleeve 39 can be fitted in the middle of the horizontal pin 21.

[0045] As a further embodiment, wear-resistant sleeves 40 are fitted at both ends of the horizontal pin 21 to reduce wear at both ends of the horizontal pin 21. The wear-resistant sleeves 40 can be made of copper or nylon.

[0046] like Figure 1 As shown, as a further embodiment, the upper part of the bushing 30 extends through the hanger 2, and the hanging ball 1 is provided with a fixing member 5 for detachably fixing the bushing 30 to the hanging ball 1. In this embodiment, the fixing member 5 is a bolt. When fixing, the bushing 30 is fixed by locking the bolt into the bushing 30 from one side of the hanging ball 1.

[0047] like Figure 10 As shown. In this application, the horizontal pin 21 and the support sleeve 32 also have another connection method, specifically implemented as follows: the upper end of the support sleeve 32 is provided with a formed insertion hole 6, the horizontal pin 21 passes through the insertion hole 6 and connects with the support sleeve 32, and a rubber sleeve 39 is fitted on the middle part of the horizontal pin 21. The support sleeve 32 is connected to the horizontal pin 21 by inserting it through the insertion hole 6, which makes the connection more stable. At the same time, the rubber sleeve 39 is also provided to prevent abnormal noise.

[0048] This utility model also provides a ceiling fan that uses the energy-absorbing hanging mechanism described above. After using the energy-absorbing hanging mechanism of this utility model, the ceiling fan can effectively reduce the vibration generated by the motor, prevent the vibration from being transmitted to the ceiling through the hanging rod 2, and thus be diffused and amplified by the ceiling. It can also prevent the hanging rod 2 from vibrating and causing the hanging frame to loosen, thus creating a safety hazard.
