Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to an air deflector driving device and an air conditioner. Background Art

[0002] Currently, in order to increase the air supply distance and refrigeration capacity of air conditioners, the market mostly adopts the method of using a driving box to drive a rack or a push rod to push out the air deflector over a large distance. Although this method meets the market's requirements for air supply distance and refrigeration capacity, it faces at least one of the following technical problems: First, it is necessary to set relatively large driving boxes on both the left and right sides of the air conditioner, resulting in an increase in the total length of the air conditioner; Second, to push out the air deflector over a large distance, the length of the rack or the push rod is required to be relatively large, resulting in an increase in the designed length of the driving box and thus an increase in the total length of the air conditioner; Third, the internal parts of the pushing mechanism including the rack or the push rod respectively require a relatively large number of components for guiding and fixing the rack or the push rod, resulting in an increase in cost and low assembly efficiency; Fourth, the driving box needs to be set to a relatively large volume, thus reducing the wiring space for accommodating the driving motor connected to the driving box, resulting in difficulties in accommodating and arranging the wiring. Summary of the Invention

[0003] Based on this, in view of the prior art, the technical problem to be solved by the present invention is to provide an air deflector driving device and an air conditioner that can reduce the number of components, occupy a small space, and reduce the length and volume of the driving box on the basis of driving the air deflector to move to achieve a relatively long-distance air supply.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] As an object of the present invention, the present invention provides an air deflector driving device, which includes: a driving box, which is provided with a fixed threaded section and an opening; a driving motor, which is arranged in the driving box; a power threaded rod, which receives the forward and reverse driving forces of the driving motor and rotates in the fixed threaded section in the corresponding forward and reverse directions; a telescopic movement assembly, which receives the driving force of the rotation of the power threaded rod to perform an outward movement or an inward movement relative to the opening; an air deflector, which is fixedly connected to the free end of the telescopic movement assembly and generates corresponding movements under the drive of the outward movement and the inward movement to enter the air guiding state and the non-air guiding state.

[0006] Further optionally, the telescopic movement component includes a first telescopic rod and a second telescopic rod. The fixed threaded section includes a first hollow portion and a first double internal thread. The power threaded rod is relatively fixedly arranged in the first hollow portion and includes a second hollow portion and a hollow double thread provided on the rod wall. The first telescopic rod is relatively movably arranged in the second hollow portion and includes a third hollow portion, a second double internal thread, and a first force receiving protrusion provided at one end closer to the power threaded rod. The first force receiving protrusion passes through the hollow double thread and is slidably engaged with the first double internal thread in a snap-fit manner. The second telescopic rod is relatively movably arranged in the third hollow portion and includes a second force receiving protrusion provided at one end closer to the first telescopic rod. The second force receiving protrusion is slidably engaged with the second double internal thread in a snap-fit manner.

[0007] Further optionally, along the axial direction from near to far relative to the drive motor, a first thread termination portion and a second thread termination portion are respectively provided at both ends of the hollow double thread. Along the axial direction from near to far relative to the power threaded rod, a third thread termination portion and a fourth thread termination portion are respectively provided at both ends of the second double internal thread. And a first guiding groove communicating with the second thread termination portion is provided on the power threaded rod, and a second guiding groove communicating with the fourth thread termination portion is provided on the first threaded rod. The first force receiving protrusion is rotatably mounted to the first thread termination portion through the first guiding groove so that the first telescopic rod is in an initial position, and the second force receiving protrusion is rotatably mounted to the third thread termination portion through the second guiding groove so that the second telescopic rod is in an initial position.

[0008] Further optionally, the first guiding grooves are provided as a pair at the free end of the power threaded rod away from the drive motor, and the pair of first guiding grooves extend and are staggered with respect to the axial and radial directions of the power threaded rod respectively. The first force receiving protrusions and the second guiding grooves are both provided as a pair and are respectively provided on the outer peripheral surface and the inner surface of the first telescopic rod, and the pair of second guiding grooves extend and are staggered with respect to the axial and radial directions of the first telescopic rod respectively. The center line of each second guiding groove is perpendicular to the center line of its adjacent first force receiving protrusion. The second force receiving protrusions are provided as a pair and are symmetric with respect to the radial direction of the second telescopic rod.

[0009] Further optionally, the first double internal thread, the hollow double thread, and the second double internal thread all have the same helical direction. The fixed threaded section, the power threaded rod, the first telescopic rod, and the second telescopic rod are all provided as cylindrical shapes and their respective outer diameters decrease in sequence.

[0010] Further optionally, a circular groove is provided at the free end of the second telescopic rod. A boss is provided on the air deflector. A through hole for inserting the free end of the second telescopic rod and a pair of jacks are provided on the boss. A pair of fixed pins are respectively inserted and fixed to the circular groove through one of the jacks.

[0011] Further optionally, the driving rod of the driving motor is provided with a driving spur gear, and a driven spur gear meshing with the driving spur gear is arranged on the side of the power threaded rod facing the driving motor.

[0012] Further optionally, the driving box includes a box body and a box cover that are fixedly connected to each other. The fixed threaded section is integrally formed on the inner surface of the box body, and an opening is provided on the box body. The power threaded rod and the driving motor are sequentially installed in the box body.

[0013] Further optionally, when the driving motor drives the power threaded rod to rotate in the first direction, while the power threaded rod rotates in the fixed threaded section, the first force receiving protrusion slides and rotates along the first double-threaded inner thread under the action of the hollow double-threaded inner thread, so that the first telescopic rod extends relative to the second hollow part. At the same time, the second force receiving protrusion slides and rotates along the second double-threaded inner thread under the action of the second double-threaded inner thread, so that the second telescopic rod extends relative to the third hollow part. When the driving motor drives the power threaded rod to rotate in the reverse direction along the second direction opposite to the first direction, while the power threaded rod rotates in the fixed threaded section, the first force receiving protrusion and the first force receiving protrusion are respectively affected by the reverse action of the hollow double-threaded inner thread and the second double-threaded inner thread, and respectively contract synchronously relative to the second hollow part and the third hollow part.

[0014] As another object of the present invention, the present invention further provides an air conditioner, which includes: a housing having an air outlet; a wind deflector driving device disposed inside the housing, and the wind deflector driving device is any one of the above wind deflector driving devices; after the telescopic movement assembly completes the extension movement, the wind deflector is in the air guiding state to guide the air outlet of the air outlet, and after the telescopic movement assembly completes the contraction movement, the wind deflector is in the non-air guiding state to block the air outlet.

[0015] Compared with the prior art, the beneficial effects of the present invention include:

[0016] First, it can meet the requirement of a long pushing distance of the wind deflector; second, the telescopic movement assembly can achieve the longest protruding distance when extending and ensure the shortest protruding distance when contracting; third, it can effectively reduce the volume of the driving box and reduce the internal guiding and fixing parts; fourth, it can provide a larger space for arranging wires for the driving motor; fifth, it can provide more space for the connection buckle required to be provided between the side plate of the air conditioner with the wind deflector driving device installed and the wind deflector surface.

Detailed implementation manners

[0042] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0043] It should be pointed out that the following detailed description is illustrative and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way limits the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0045] Referring to Figures 1 to 24 , as an object of the present invention, an embodiment of the present invention provides an air deflector driving device, which includes a driving box 1, a driving motor 3, a power lead screw 4, a telescopic movement assembly, and an air deflector 7. The driving box 1 is provided with a fixed thread section 2 and an opening 111. The driving motor 3 is disposed in the driving box 1. The power lead screw 4 receives the forward and reverse driving forces of the driving motor 3 and rotates in the fixed thread section 2 in the corresponding forward and reverse directions. That is to say, the power lead screw 4 has a clearance fit with the fixed thread section 2 so that there is only relative circumferential rotation and no axial movement. The telescopic movement assembly receives the driving force of the rotation of the power lead screw 4 to perform an outward movement or an inward movement relative to the opening 111. The air deflector 7 is fixedly connected to the free end of the telescopic movement assembly and moves correspondingly under the drive of the outward movement and the inward movement to enter the air guiding state and the non-air guiding state. It can be seen from this that since the telescopic movement assembly is only stressed and elongated when it is necessary to push out the air deflector 7 for air guiding, and in other cases, the telescopic movement assembly is in a contracted state. Therefore, fewer components are used to drive the movement of the air deflector 7, which not only reduces the cost and improves the assembly efficiency, but also enables the volume of the driving box 1 to be set smaller, thereby helping to reduce the total length of the air conditioner, and also increasing the space for accommodating the wiring of the motor, thus facilitating the accommodation of the wiring and reducing the wiring difficulty.

[0046] Please further refer to Figure 3 , Figure 7 , Figures 15 to 19, specifically, the telescopic movement assembly includes a first telescopic rod 5 and a second telescopic rod 6. The fixed threaded section 2 includes a first hollow part and a first double - headed internal thread 21. The power threaded rod 4 is relatively fixedly arranged in the first hollow part and includes a second hollow part and a hollow double - headed thread 41 provided on the rod wall. The first telescopic rod 5 is movably arranged in the second hollow part and includes a third hollow part, a second double - headed internal thread 51, and a first force - receiving protrusion 52 provided at the end closer to the power threaded rod 4. It can be inferred that the other end of the first telescopic rod 5 opposite to the end where the first force - receiving protrusion 52 is provided is closer to the second telescopic rod 6. The first force - receiving protrusion 52 passes through the hollow double - headed thread 41 and is in sliding and clamping fit with the first double - headed internal thread 21. The second telescopic rod 6 is movably arranged in the third hollow part and includes a second force - receiving protrusion 61 provided at the end closer to the first telescopic rod 5. It can be inferred that the other end of the second telescopic rod 6 opposite to the end where the first force - receiving protrusion 52 is provided serves as the free end of the telescopic movement assembly to be fixedly connected to the air deflector 7. Additionally, in this embodiment, the radius of the above - mentioned first double - headed internal thread 21 is set to 1 mm, and both the first force - receiving protrusion 52 and the second force - receiving protrusion 61 are set as cuboids with dimensions: length: 2 mm, width: 1 mm, height: 2 mm. The second force - receiving protrusion 61 is in sliding and clamping fit with the second double - headed internal thread 51. As described above, through the first force - receiving protrusion 52 and the second force - receiving protrusion 61, the axial components of the spiral thrusts received from the hollow double - headed thread 41 and the second double - headed internal thread 51 respectively cause the first telescopic rod 5 and the second telescopic rod 6 to extend or contract along the axial direction. Not only is the synchronization and stability of the movement of the first telescopic rod 5 and the second telescopic rod 6 good, but also the unit distance of the movement can be precisely controlled.

[0047] Preferably, along the axial direction from near to far relative to the drive motor 3, a first thread termination portion 411 and a second thread termination portion 412 are respectively provided at both ends of the hollow double - threaded portion 41. That is, the hollow double - threaded portion 41 is only provided between the first thread termination portion 411 and the second thread termination portion 412. Along the axial direction from near to far relative to the power screw rod 4, a third thread termination portion 511 and a fourth thread termination portion 512 are respectively provided at both ends of the second double - internal thread 51. That is, the second double - internal thread 51 is only provided between the third thread termination portion 511 and the fourth thread termination portion 512. Therefore, by precisely setting the positions and corresponding relationships of the respective thread termination portions, the movement distances and relative movement relationships of the first telescopic rod 5 and the second telescopic rod 6 can be accurately defined. When the first force - receiving protrusion 52 and the second force - receiving protrusion 61 respectively move to the second thread termination portion 412 and the fourth thread termination portion 512, the total extended distance of the first telescopic rod 5 and the second telescopic rod 6 is the longest, so that the air deflector 7 can be pushed out a large distance, enabling the air conditioner to obtain a large air supply distance and refrigeration capacity. And a first guide groove 413 communicating with the second thread termination portion 412 is provided on the power screw rod 4, and a second guide groove 513 communicating with the fourth thread termination portion 512 is provided on the first screw rod. The first force - receiving protrusion 52 is rotatably installed to the first thread termination portion 411 through the first guide groove 413 to make the first telescopic rod 5 in the initial position, and the second force - receiving protrusion 61 is rotatably installed to the third thread termination portion 511 through the second guide groove 513 to make the second telescopic rod 6 in the initial position. Therefore, by providing the two guide grooves, it is convenient to install each force - receiving protrusion into the corresponding thread termination portion. Both of these initial positions correspond to the air deflector 7 being in the non - air - guiding state. It can be known that the above - mentioned rotation direction is opposite to the rotation direction of the drive motor 3 driving the power screw rod 4 to make the first telescopic rod 5 and the second telescopic rod 6 perform the outward extension movement.

[0048] Preferably, a pair of first guiding grooves 413 are arranged at the end of the power screw rod 4 away from the free end of the driving motor 3. The pair of first guiding grooves 413 extend axially and radially with respect to the power screw rod 4 and are staggered from each other. The first force - receiving protrusions 52 and the second guiding grooves 513 are both arranged in pairs and are respectively provided on the outer peripheral surface and the inner surface of the first telescopic rod 5. The pair of second guiding grooves 513 extend axially and radially with respect to the first telescopic rod 5 and are staggered from each other. The center line of each second guiding groove 513 is perpendicular to the center line of its adjacent first force - receiving protrusion 52. The second force - receiving protrusions 61 are arranged in pairs and are symmetric with respect to the radial direction of the second telescopic rod 6. In this way, by arranging a pair of first force - receiving protrusions 52 and a pair of second guiding grooves 513 and arranging the four of them evenly in the radial direction of the first telescopic rod 5, it is beneficial to the stability of the overall movement of the first telescopic rod 5. Moreover, each pair of force - receiving protrusions is arranged radially symmetrically, which correspondingly ensures that each telescopic rod is evenly stressed. Furthermore, the above two staggered designs ensure the accurate positioning of each force - receiving protrusion when entering the internal thread through the guiding groove and facilitate subsequent rotational assembly.

[0049] Preferably, the first double - thread internal thread 21, the hollow double - thread 41, and the second double - thread internal thread 51 all have the same - handed helix. It should be understood that the minor diameter value of the hollow double - thread 41 is greater than the outer diameter value of the first telescopic rod 5, so as to avoid interference between the first telescopic rod 5 and the hollow double - thread 41 during the relative movement in the power screw rod 4. The major diameter value of the first double - thread internal thread 21 is greater than the diameter of the circle where the highest point of the first force - receiving protrusion 52 relative to the axis of the first telescopic rod 5 is located, and the specific value of this excess is set to about 0.5 mm. In this way, it can be avoided that the first force - receiving protrusion 52 is stuck and stops rotating due to interference fit during the relative movement in the first double - thread internal thread 21. Similarly, the minor diameter value of the second double - thread internal thread 51 is greater than the outer diameter value of the second telescopic rod 6, so as to avoid interference between the second telescopic rod 6 and the second double - thread internal thread 51 during the relative movement in the first telescopic rod 5. The major diameter value of the second double - thread internal thread 51 is greater than the diameter of the circle where the highest point of the second force - receiving protrusion 61 relative to the axis of the second telescopic rod 6 is located, and the specific value of this excess is set to about 0.5 mm. In this way, it can be avoided that the second force - receiving protrusion 61 is stuck and stops rotating due to interference fit during the relative movement in the second double - thread internal thread 51. The fixed - thread section 2, the power screw rod 4, the first telescopic rod, and the second telescopic rod 6 are all cylindrical and their outer diameters decrease in sequence. Therefore, since the first telescopic rod 5 and the second telescopic rod 6 can both be retracted into the power screw rod 4, the occupied space can be greatly reduced, thus reducing the overall volume of the driving box 1.

[0050] Please refer further to Figure 19 、 Figures 20 to 24, preferably, a circular groove 62 is provided at the free end of the second telescopic rod 6, a boss is provided on the air deflector 7, and a through hole 711 for inserting the free end of the second telescopic rod 6 and a pair of jacks 712 are provided on the boss. A pair of fixing pins 8 are respectively inserted and fixed with the circular groove 62 through a jack 712. In this way, by adopting the plug-in fixing method, the free end of the second telescopic rod 6 is firmly fixed to the air deflector 7, ensuring the accurate synchronous movement of the air deflector 7 with the second telescopic rod 6.

[0051] Please further refer to Figure 11 and Figure 14 , preferably, a driving rod of the driving motor 3 is provided with a driving spur gear (not shown), and a driven spur gear 42 meshing with the driving spur gear is provided on one side of the power screw rod 4 facing the driving motor 3. Since the driven spur gear 42 is directly fixed on one side surface of the power screw rod 4, the number of gear pairs is advantageously reduced, and the volume of the driving box 1 is further reduced.

[0052] Please further refer to Figure 7 , preferably, the driving box 1 includes a box body 11 and a box cover 12 which are fixedly connected to each other, a receiving space is formed between the box body 11 and the box cover 12, the fixed threaded section 2 is integrally formed on the inner surface of the box body 11, an opening 111 is provided on the box body 11, and the power screw rod 4 and the driving motor 3 are sequentially installed into the box body 11. By integrally forming the fixed threaded section 2 with the box body 11, the disadvantages of increasing parts and cost caused by separately manufacturing the fixed threaded section 2 are avoided, the assembly steps are reduced, and after the power screw rod 4 is installed, the driving motor 3 is installed, and the driving motor 3 can be used to well limit the power screw rod 4.

[0053] Please further refer to Figure 6 , preferably, when the driving motor 3 drives the power screw rod 4 to rotate in the counterclockwise direction as the first direction along the orientation shown in, for example, Figure 6 , while the power screw rod 4 rotates in the fixed threaded section 2, the first force receiving protrusion 52 slides and rotates along the first double internal thread 21 under the action of the hollow double thread 41, so that the first telescopic rod 5 moves outward relative to the second hollow part. At the same time, the second force receiving protrusion 61 slides and rotates along the second double internal thread 51 under the action of the second double internal thread 51, so that the second telescopic rod 6 moves outward relative to the third hollow part. That is to say, the first telescopic rod 5 and the second telescopic rod 6 move synchronously. When the driving motor 3 rotates in the direction opposite to the first direction, for example, Figure 6When the second-direction driving power screw rod 4 rotates in the counterclockwise direction with respect to the shown orientation, while the power screw rod 4 rotates in the fixed thread section 2, the first force-receiving protrusions 52 and 52 respectively receive the counter-direction actions of the hollow double-thread 41 and the second double internal thread 51, and thus respectively and synchronously perform retraction movements relative to the second hollow part and the third hollow part. The process of this retraction movement is opposite to the above-described extension movement process, and can be deduced by reference, so it will not be elaborated here. Therefore, by using the forward and reverse rotations of the driving motor 3, such as clockwise rotation or counterclockwise rotation, to drive the power screw rod 4 to rotate in one of the two different directions, the first telescopic rod 5 obtains the power of the power screw rod 4, and at the same time the second telescopic rod 6 also obtains the power of the first telescopic rod 5, so that the two telescopic rods correspondingly rotate out or rotate in, reliably and synchronously realizing the extension movement or the retraction movement.

[0054] Please further refer to Figures 20 to 24 As another object of the present invention, another embodiment of the present invention provides an air conditioner, which includes a housing (not shown) having an air outlet and a wind deflector driving device. Preferably, two wind deflector driving devices are respectively arranged at both ends of the wind deflector 7, so that the pushing and retracting of the wind deflector 7 can be more stable. The wind deflector driving device is arranged inside the housing and is any one of the above-mentioned wind deflector driving devices. The wind deflector driving device has the beneficial effects of any one of the above-mentioned wind deflector driving devices, which will not be elaborated here. After the telescopic movement assembly completes the extension movement, the wind deflector 7 is in the air guiding state to guide the air outlet of the air outlet. After the telescopic movement assembly completes the retraction movement, the wind deflector 7 is in the non-air guiding state to block the air outlet. Since the air conditioner adopts the driving box 1 with reduced volume, fewer components, and accurate and stable movement, the air conditioner has the advantages of reducing the total length of the air conditioner, improving the assembly efficiency, simplifying the wiring of the driving motor 3, accurate movement orientation of the wind deflector 7, and good air guiding effect.
