Description

Technical Field

[0001] The present application relates to but is not limited to the field of air-conditioning technology, and in particular to but is not limited to a transmission mechanism and an air conditioner. Background Art

[0002] The air conditioner adjusts the blowing direction through the air guide plate to make the temperature and air volume in the room more uniform. When the air guide plate is turned off, the drive motor of the air guide plate is usually blocked to make the air guide plate close more tightly. However, the drive motor is blocked, resulting in the following problems:

[0003] 1. The air guide plate makes a clicking sound when it is closed;

[0004] 2. The air guide plate will twist and deform when it is closed;

[0005] 3. It will affect the life of its drive motor;

[0006] 4. The drive motor is easily damaged when the air guide plate is manually opened. It is necessary to indicate in the instruction manual or on the machine body that the air guide plate cannot be opened manually. However, there are still customers who directly open the air guide plate, resulting in the need for after-sales repairs.

[0007] In some cases, an electronic control scheme is used to prevent the drive motor from stalling, such as adding a photoelectric gate, Hall switch, overload protector, or setting reverse logic to prevent the air guide from being in a twisted state, which increases costs and has relatively poor reliability. In some other cases, a motor with a memory function is used, and the motor stops after rotating to a certain angle to prevent stalling, but the cost of the motor with a memory function increases. Summary of the invention

[0008] The purpose of the embodiments of the present application is to provide a transmission mechanism that can prevent the drive motor from stalling and has low cost.

[0009] The transmission mechanism provided in the embodiment of the present application includes:

[0010] a rotatable power input member;

[0011] at least one planetary gear rotatably mounted to the power input member;

[0012] a damping member disposed between the planetary gear and the power input member; and

[0013] A power output member, comprising a gear structure meshing with the planetary gear;

[0014] The transmission mechanism has a transmission state and a non-transmission state. In the transmission state, the planetary gear is arranged to be stationary relative to the power input member under the damping action of the damping member, and the power output member is arranged to be able to rotate under the drive of the rotating power input member; in the non-transmission state, the planetary gear is arranged to overcome the damping action of the damping member and rotate relative to the power input member, and the power output member is arranged not to rotate under the drive of the rotating power input member.

[0015] An embodiment of the present application further provides an air conditioner, comprising a power element, an air guide structure and the above-mentioned transmission mechanism, wherein the power element is connected to the power input component, and the air guide structure is connected to the power output component.

[0016] The transmission mechanism provided in the embodiment of the present application is mainly composed of a power input member, a planetary gear, a power output member and a damping member. The power input member can rotate under the drive of the power element, which is called revolution. Since the planetary gear is installed on the power input member, the planetary gear will also revolve like the power input member; a damping member is provided at the connection position between the planetary gear and the power input member, and the planetary gear can rotate relative to the power input member, and this rotation is called the rotation of the planetary gear.

[0017] In the transmission mechanism of the embodiment of the present application, the planetary wheel is subjected to the damping force of the damping member on the one hand, and the load force applied by the load through the power output member on the other hand. The magnitude relationship between the torque of the load force and the torque of the damping force is different, which causes the planetary wheel to rotate with the power input member or to be stationary relative to the power input member, thereby making the transmission mechanism have a transmission state and a non-transmission state. Among them, in the transmission state, the torque of the load force received by the planetary wheel is less than the torque of the damping force. At this time, the planetary wheel cannot overcome the damping effect of the damping member and rotate relative to the power input member, but is stationary relative to the power input member. In this case, when the power element drives the power input member to rotate, the planetary wheel only revolves with the power input member, but does not rotate. The power input member can drive the power output member to rotate through the planetary wheel to achieve power transmission from the power input member to the power output member. In the non-transmission state, the torque of the load force applied to the planetary gear is greater than the torque of the damping force. At this time, the planetary gear can overcome the damping effect of the damping element and rotate relative to the power input component. In this case, when the power element drives the power input component to rotate, the planetary gear not only revolves with the power input component, but also rotates on its own. The power input component cannot drive the power output component to rotate through the planetary gear, and power cannot be transmitted from the power input component to the power output component.

[0018] When the transmission mechanism of the embodiment of the present application is used in an air conditioner, the power element may include a driving motor of the air guide plate, and the load may include the air guide plate. When the air guide plate needs to be opened or swung, the power output component only has the air guide plate as a load, and the planetary gear will not rotate. At this time, the transmission mechanism is in a transmission state, and the planetary gear will transmit all the power to the power output component to drive the air guide plate to rotate accordingly. When the air guide plate needs to be closed, after the air guide plate rotates to the extreme position, it will not continue to rotate due to the action of the limiting mechanism of the air conditioner, which is equivalent to the load on the power output component becoming larger. When the drive motor continuously inputs power, the planetary gear overcomes the friction of the damping member and rotates. At this time, the transmission mechanism is in a non-transmission state, and the planetary gear cannot transmit power to the power output component, resulting in the situation that the power input component and the drive motor continue to revolve, the planetary gear continues to revolve and rotate, and the power output component and the air guide plate do not rotate. This situation can avoid the situation where the drive motor has torque output but the speed is zero, thereby increasing the life of the drive motor and preventing the rattling sound. It can also prevent the air guide plate from continuously receiving the torque of the drive motor and causing torsional deformation. There is no need to design a complex reversal program in the control logic. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0038] like Figure 1-Figure 5 As shown, the embodiment of the present application provides a transmission mechanism 100, including: a rotatable power input member 1, a planetary gear 2, a damping member 3 and a power output member 4. The power input member 1 is configured to be connected to a power element 6 and can rotate under the drive of the power element 6; the planetary gear 2 is rotatably mounted to the power input member 1, and the damping member 3 is arranged between the planetary gear 2 and the power input member 1; the power output member 4 is configured to be connected to a load, and the power output member 4 includes a gear structure 41 meshing with the planetary gear 2.

[0039] The transmission mechanism 100 has a transmission state and a non-transmission state. In the transmission state, the planetary gear 2 is stationary relative to the power input component 1 under the damping action of the damping member 3, and the power output component 4 can rotate under the drive of the rotating power input component 1; in the non-transmission state, the planetary gear 2 can overcome the damping action of the damping member 3 and rotate relative to the power input component 1, and the power output component 4 does not rotate under the drive of the rotating power input component 1.

[0040] The transmission mechanism 100 of the embodiment of the present application is mainly composed of a power input component 1, a planetary gear 2, a power output component 4 and a damping member 3. One end of the power input component 1 can be connected to the power element 6, and the other end can be installed with the planetary gear 2. The power input component 1 can rotate driven by the power element 6, which is called revolution. Because the planetary gear 2 is installed on the power input component 1, the planetary gear 2 will also revolve like the power input component 1. A damping member 3 is provided at the connection position between the planetary gear 2 and the power input component 1. The planetary gear 2 can rotate relative to the power input component 1. This rotation is called the rotation of the planetary gear 2. One end of the power output component 4 can be connected to the load, and the other end is a gear structure 41, and the gear structure 41 is meshed with the planetary gear 2.

[0041] In the transmission mechanism 100 of the embodiment of the present application, the planetary gear 2 is subjected to the damping force of the damping member 3 on the one hand, and the load force applied by the load through the power output member 4 on the other hand. The magnitude relationship between the torque of the load force and the torque of the damping force is different, resulting in the planetary gear 2 being able to rotate with the power input member 1 or being stationary relative to the power input member 1, thereby making the transmission mechanism 100 have a transmission state and a non-transmission state. Among them, in the transmission state, the torque of the load force on the planetary gear 2 is less than the torque of the damping force. At this time, the planetary gear 2 cannot overcome the damping effect of the damping member 3 and rotate relative to the power input member 1, but is stationary relative to the power input member 1. In this case, when the power element 6 drives the power input member 1 to rotate, the planetary gear 2 only revolves with the power input member 1, but does not rotate. The power input member 1 can drive the power output member 4 to rotate through the planetary gear 2 to achieve power transmission from the power input member 1 to the power output member 4. In the non-transmission state, the torque of the load force on the planetary gear 2 is greater than the torque of the damping force. At this time, the planetary gear 2 can overcome the damping effect of the damping element 3 and rotate relative to the power input component 1. In this case, when the power element 6 drives the power input component 1 to rotate, the planetary gear 2 not only revolves with the power input component 1, but also rotates at the same time. The power input component 1 cannot drive the power output component 4 to rotate through the planetary gear 2, and the power cannot be transmitted from the power input component 1 to the power output component 4.

[0042] like Figure 6-Figure 10 As shown, when the transmission mechanism 100 of the embodiment of the present application is used in an air conditioner, the power element 6 may include a driving motor of the air guide plate 7 , and the load may include the air guide plate 7 .

[0043] When the air guide plate 7 needs to be opened or swung, the power output component 4 only has the air guide plate 7 as a load, and the planetary gear 2 will not rotate. At this time, the transmission mechanism 100 is in a transmission state, and the planetary gear 2 will transmit all the power to the power output component 4 to drive the air guide plate 7 to rotate accordingly.

[0044] When the air guide plate 7 needs to be closed, after the air guide plate 7 rotates to the extreme position, it will not continue to rotate due to the action of the air conditioner's limit mechanism, which is equivalent to the load on the power output component 4 becoming larger. When the drive motor continues to input power, the planetary gear 2 overcomes the friction of the damping member 3 and rotates. At this time, the transmission mechanism 100 is in a non-transmission state, and the planetary gear 2 cannot transmit power to the power output component 4. The power input component 1 and the drive motor continue to revolve, the planetary gear 2 continues to revolve and rotate, and the power output component 4 and the air guide plate 7 do not rotate. This situation can avoid the situation where the drive motor has torque output but the speed is zero, which increases the life of the drive motor and does not make a rattling sound; it can also avoid the air guide plate 7 from continuously receiving the torque of the drive motor and causing torsional deformation; and there is no need to design a complex reversal program in terms of control logic.

[0045] Therefore, when the transmission mechanism 100 of the embodiment of the present application is used in an air conditioner to transmit the power of the driving motor to the air guide plate 7, it has the following advantages:

[0046] 1. Eliminate the abnormal sound generated when the air guide plate 7 is closed, and improve the comfort of product use;

[0047] 2. Prevent the air guide plate 7 from twisting and deforming when it is closed, thereby improving product quality;

[0048] 3. The drive motor will not be blocked, which increases the life of the drive motor, or a lower-cost drive motor can be used and meet the life requirements;

[0049] 4. Manually breaking the air guide plate 7 will not damage the drive motor, thus avoiding maintenance costs and damaging product quality;

[0050] 5. No need to set components to detect stalling, which reduces the risk of failure caused by component damage and saves costs.

[0051] In some exemplary embodiments, Figure 1-Figure 5 As shown, the power input member 1 may include a first connection portion 11 and a mounting portion 12 connected to each other, the first connection portion 11 is configured to be connectable to the power element 6 , and the mounting portion 12 is configured to mount the planetary gear 2 .

[0054] In some exemplary embodiments, the planetary gear 2 may be provided with one; or, Figure 1-Figure 5 As shown, there may be a plurality of planetary gears 2 , and all of the plurality of planetary gears 2 may mesh with the gear structure 41 .

[0055] In the transmission mechanism 100, the planetary gear 2 may be provided with a transmission state, and the transmission mechanism 100 may be switched between the transmission state and the non-transmission state by whether the planetary gear 2 rotates or not; or Figure 1-Figure 5 As shown, there are multiple (eg, two, three or more) planetary gears 2, and all of the multiple planetary gears 2 are meshed with the gear structure 41 to make the rotation of the power output component 4 smoother, thereby making the transmission of the transmission mechanism 100 smoother.

At this time, the two planetary wheels 2 are symmetrically distributed on both sides of the gear structure 41, so that the gear structure 41 is subjected to balanced force and the rotation of the power output component 4 is smoother.

[0059] In order to achieve the connection between the mounting portion 12 and the first connecting portion 11, and to install the two planetary gears 2, the mounting portion 12 can be configured to be a U-shaped frame formed by connecting a mounting end wall 125 and two mounting side walls 126. The first connecting portion 11 can be located outside the U-shaped frame, and one end of the first connecting portion 11 can be connected to the mounting end wall 125, and the other end can extend toward a side away from the mounting side wall 126 so as to be connected to the power element 6; both planetary gears 2 can be located in the U-shaped frame, and the two planetary gears 2 can be respectively installed on the two mounting side walls 126, the gear structure 41 at one end of the power output member 4 is located on a side of the two planetary gears 2 away from the mounting end wall 125, so that the gear structure 41 engages with the two planetary gears 2, and the other end of the power output member 4 can extend toward a side away from the mounting end wall 125 so as to be connected to the load.

[0060] The transmission mechanism 100 has a reasonable structural arrangement and a compact layout, which is conducive to reducing the size of the transmission mechanism 100.

[0061] In some other exemplary embodiments, Figure 3 and Figure 4 As shown, there are at least three planetary gears 2 , which are arranged along the circumference of the mounting portion 12 , and the gear structure 41 is located on one side of the at least three planetary gears 2 .

[0062] In the transmission mechanism 100, at least three (e.g., three or more) planetary gears 2 may be provided, and at least three planetary gears 2 may be arranged at intervals along the circumference of the mounting portion 12, and the gear structure 41 of the power output member 4 may be located on one side of the at least three planetary gears 2, so that the gear structure 41 is simultaneously meshed with the at least three planetary gears 2. Among them, the at least three planetary gears 2 may be evenly distributed along the circumference of the mounting portion 12, so that the gear structure 41 is evenly stressed, and the rotation of the power output member 4 is smoother.

[0064] In order to achieve the connection between the mounting portion 12 and the first connecting portion 11, and to install at least three planetary gears 2, the mounting portion 12 can be configured to include a mounting end wall 125 and an annular mounting side wall 126, the first connecting portion 11 can be located outside the mounting cavity surrounded by the mounting end wall 125 and the mounting side wall 126, and one end of the first connecting portion 11 can be connected to the mounting end wall 125, and the other end can extend toward a side away from the mounting side wall 126 so as to be connected to the power element 6; at least three planetary gears 2 can be located in the mounting side wall 126, and at least three planetary gears 2 can be evenly distributed along the circumference of the mounting side wall 126, the gear structure 41 at one end of the power output member 4 is located on a side of the at least three planetary gears 2 away from the mounting end wall 125, so that the gear structure 41 is meshed with the at least three planetary gears 2 at the same time, and the other end of the power output member 4 can extend toward a side away from the mounting end wall 125 so as to be connected to the load.

[0065] The transmission mechanism 100 has a reasonable structural arrangement and a compact overall layout, which is conducive to reducing the size of the transmission mechanism 100.

[0066] In some exemplary embodiments, Figure 5 As shown, the transmission mechanism 100 may further include an auxiliary wheel 5 , which is rotatably mounted to the mounting portion 12 and can mesh with the planetary gear 2 , and the auxiliary wheel 5 and the gear structure 41 are symmetrically arranged on both sides of the planetary gear 2 .

[0067] In order to prevent the planetary wheel 2 from being deflected due to the force of the gear structure 41 of the power output member 4 acting on one side of the planetary wheel 2, an auxiliary wheel 5 may be provided on the other side of the planetary wheel 2, symmetrically to the gear structure 41, and the auxiliary wheel 5 is meshed with the planetary wheel 2 and may also rotate when the planetary wheel 2 rotates. Since the auxiliary wheel 5 and the gear structure 41 are symmetrically provided on both sides of the planetary wheel 2, the forces on both sides of the planetary wheel 2 are balanced, thereby preventing the planetary wheel 2 from being deflected due to the unbalanced forces, thereby affecting the transmission performance of the transmission mechanism 100.

[0068] In some exemplary embodiments, Figure 5 As shown, the auxiliary wheel 5 is rotatably mounted on the mounting end wall 125 of the mounting portion 12 of the power input component 1. At this time, the auxiliary wheel 5 is arranged on the side of the planetary wheel 2 close to the mounting end wall 125, and the gear structure 41 of the power output component 4 is arranged on the side of the planetary wheel 2 away from the mounting end wall 125, so that the auxiliary wheel 5 and the gear structure 41 can be symmetrically arranged on both sides of the planetary wheel 2 to ensure that the forces on both sides of the planetary wheel 2 are balanced.

[0069] exist Figure 5 In the embodiment shown, the auxiliary wheel 5 can be located in the U-shaped frame and rotatably mounted on the mounting end wall 125, and the auxiliary wheel 5 is meshed with the two planetary wheels 2 at the same time, so that the two planetary wheels 2 are subjected to balanced forces; or Figure 3 and Figure 4 In the illustrated embodiment, an auxiliary wheel (not shown) may be located in an installation cavity surrounded by the installation end wall 125 and the installation side wall 126, and may be rotatably installed on the installation end wall 125, and the auxiliary wheel may be meshed with at least three planetary wheels 2 at the same time, so that at least three planetary wheels 2 are subjected to balanced force.

[0070] In some exemplary embodiments, Figure 2 As shown, a gear shaft 21 is provided at one end of the planetary gear 2, and the power input member 1 is provided with an axial hole 124, and the gear shaft 21 is rotatably mounted to the axial hole 124. Further, the transmission mechanism 100 may also include a fastening screw 22, which may extend into the axial hole 124 and be threadedly connected to the gear shaft 21.

[0071] The mounting side wall 126 of the power input member 1 may be provided with an axial hole 124, and the gear shaft 21 of the planetary gear 2 may be mounted to the axial hole 124; the gear shaft 21 may be provided with a threaded hole, and the fastening screw 22 may extend from the outside of the U-shaped frame into the axial hole 124 (at Figure 1 , Figure 2 and Figure 5 Alternatively, the fastening screw 22 may extend from the outer side of the annular mounting side wall 126 into the shaft hole 124 (in the embodiment shown in FIG. Figure 3 and Figure 4 In the embodiment shown in the figure), the fastening screw 22 can be screwed with the threaded hole on the gear shaft 21 to achieve the rotatable installation of the planetary gear 2 to the power input member 1.

[0072] In some exemplary embodiments, Figure 2 As shown, the damping member 3 can be an annular member and sleeved outside the gear shaft 21, and the damping member 3 can be sandwiched between the gear shaft 21 and the hole wall of the shaft hole 124 of the power input member 1. The damping member 3 can be a rubber ring or a silicone ring or other elastic member, and the damping member 3 can be squeezed by the gear shaft 21 and the hole wall of the shaft hole 124 to be deformed.

[0073] In the transmission mechanism 100, the damping member 3 is sandwiched in the gap between the gear shaft 21 of the planetary gear 2 and the hole wall of the shaft hole 124 of the power input member 1. Since the damping member 3 is provided between the planetary gear 2 and the power input member 1, the damping member 3 will form a certain amount of friction, and the planetary gear 2 needs to overcome the friction of the damping member 3 when it rotates. The friction of the damping member 3 can be adjusted by changing the amount of interference between the damping member 3 and the gear shaft 21, such as by changing the wall thickness of the damping member 3 to change the deformation of the damping member 3, thereby changing the friction applied by the damping member 3 to the planetary gear 2.

[0074] In some other exemplary embodiments, the damping element 3 may be sandwiched between the screw head of the fastening screw 22 and the power input member 1 .

[0075] The damping member 3 may be an annular member, the fastening screw 22 may pass through the damping member 3, and the damping member 3 may be clamped between the screw head of the fastening screw 22 and the outer wall surface of the mounting side wall 126 of the power input member 1. The damping member 3 may be a rubber ring or a silicone ring or other elastic member, and the damping member 3 may be deformed by the squeezing of the screw head of the fastening screw 22 and the power input member 1. Since the damping member 3 is provided between the planetary gear 2 and the power input member 1, the damping member 3 will form a certain amount of friction, and the planetary gear 2 needs to overcome the friction of the damping member 3 when rotating. The friction of the damping member 3 can be adjusted by changing the degree of pressure and deformation of the damping member 3, such as: the degree of pressure and deformation of the damping member 3 can be adjusted by screwing the fastening screw 22.

[0076] In some exemplary embodiments, Figure 1-Figure 5 As shown, the planetary gear 2, the gear structure 41 of the power output member 4 and the auxiliary wheel 5 are all bevel gears (such as spur bevel gears), and the rotation axes of the power input member 1 and the power output member 4 can coincide.

[0077] It should be understood that the planetary gear 2, the gear structure 41 of the power output member 4 and the auxiliary wheel 5 are not limited to be bevel gears, but may also be other forms of gears, such as spur gears.

[0078] In some exemplary embodiments, Figure 1-Figure 5 As shown, the power output component 4 further includes a second connection portion 42, which is configured to be connected to a load, and the gear structure 41 and the second connection portion 42 are an integrated structure or a split fixed structure.

[0079] In some exemplary embodiments, Figure 1-Figure 5 As shown, the mounting portion 12 and the first connecting portion 11 of the power input member 1 may be an integral structure, or may be a separate fixed structure.
