Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to a door panel drive mechanism and an air conditioner. Background Technology

[0002] In existing technologies, floor-standing air conditioner units generally use open air vents, and the opening and closing of the vents is controlled by the circular rotation of the sliding door panel. This prevents foreign objects from entering the air conditioner and also maintains the overall appearance of the unit. The sliding door panel's transmission method is mostly a rigid transmission between gears and racks. The rack drives the sliding door panel to rotate in a circular motion to open and close the air vents. To ensure smooth and interference-free movement of the sliding door panel, a certain clearance needs to be maintained between the front panel and the sliding door panel.

[0003] Therefore, when the air outlet is covered, i.e., the sliding door is closed, the sliding door is inevitably inside the front panel, and cannot fit tightly against it. This not only affects the overall appearance of the unit, but also allows dust and cockroaches to easily enter the air conditioner through the gap between the sliding door and the front panel, affecting the air conditioner's cleanliness and operating efficiency, and reducing the user experience.

[0037] Please refer to Figures 1 to 14 This utility model provides a door panel driving mechanism, including: a transmission assembly, which is connected to a door panel 60. The transmission assembly is movably arranged along a predetermined trajectory position to drive the door panel 60 to move relative to the flow opening 1 until it moves to an open position or a closed position; wherein, the transmission assembly includes a pusher 10 and a slider 30. The pusher 10 is connected to the door panel 60, and the pusher 10 and the slider 30 are positionally adjustable so that when the transmission assembly drives the door panel 60 to move to the closed position, the pusher 10 and the door panel 60 move relative to the slider 30 in a predetermined direction to seal the flow opening 1.

[0038] The door panel driving mechanism of this utility model includes a transmission assembly, which includes a pusher 10 and a slider 30. The pusher 10 is used to connect with the door panel 60. The pusher 10 and the slider 30 are connected in an adjustable position. The transmission assembly drives the door panel 60 to move to the closed position to close the flow opening 1. Then, the pusher 10 and the door panel 60 move relative to the slider 30 in a preset direction to seal the flow opening 1. Even if the door panel 60 is tightly attached to the front panel 70, the door panel 60 and the inner wall of the front panel 70 are in sealed contact, avoiding a large gap between the door panel and the front panel 70 when the door panel is closed. This solves the problem of a large gap between the air conditioner sliding door panel and the front panel 70 when closed in the prior art, preventing dust, cockroaches, etc. from entering the air conditioner from the gap, while ensuring the overall appearance of the air conditioner.

[0039] Specifically, the flow opening 1 is an air outlet, located on the front panel 70; the motion trajectory formed by the sliding member 30 rotating clockwise or counterclockwise around the axis of the drive shaft 801 is the predetermined trajectory. The sliding member 30 has a fan-shaped structure, and the flow opening 1 is an arc-shaped opening. The extension direction of the line connecting the center line of the flow opening 1 and the axis of the drive shaft 801 is the preset direction, which also extends radially along the sliding member 30. The preset direction is as follows: Figure 5 The x-direction is shown.

[0040] Furthermore, since the transmission method of sliding door panels is mostly a rigid transmission between gear 202 and rack, with the rack driving the sliding door panel to rotate in a circular motion to open and close the air outlet, the motion mechanism design is complex, resulting in high precision requirements for the moving parts, low assembly efficiency, and inconvenient maintenance. In contrast, this application uses the rotation of the sliding member 30 around the axis of the drive shaft 801 to directly drive the push member 10 and the door panel 60 to move along a predetermined trajectory to open and close the air outlet. The motion mechanism design is simple, resulting in low precision requirements for the moving parts, high assembly efficiency, and convenient maintenance.

[0041] This utility model designs a simple door panel drive mechanism. A sliding member 30 drives a pushing member 10 and a door panel 60 to move along a predetermined trajectory. The pushing member 10 and the door panel 60 move relative to the sliding member 30 in a preset direction, causing the door panel 60 to close the flow opening 1 and seal it. This effectively reduces the gap between the door panel 60 and the front panel 70, preventing dust, cockroaches, and other contaminants from entering the air conditioner through the gap, while maintaining the overall appearance of the air conditioner. Simultaneously, it solves the problem of numerous moving parts and complex assembly, simplifying the entire drive mechanism, reducing the number of assembly parts, thereby reducing space occupancy, improving the assembly efficiency of the door panel drive mechanism, and facilitating subsequent air conditioner maintenance.

[0042] In this embodiment, the pusher 10 includes a push rod body 101, which is slidably connected to the slider 30 and also connected to the door panel 60. The door panel driving mechanism also includes a first driving assembly 20, which includes a gear 202. The gear 202 is rotatably arranged around the axis of the gear 202. The push rod body 101 is provided with a plurality of meshing teeth 102, which are spaced apart along a preset direction. Each meshing tooth 102 can mesh with the gear 202 so that the first driving assembly 20 drives the pusher 10 to move.

[0043] Specifically, by meshing gear 202 with multiple meshing teeth 102, the transmission connection between gear 202 and pusher 10 is ensured, and the first drive assembly 20 can drive pusher 10 to move smoothly and controllably in a preset direction, thereby ensuring that door panel 60 can seal the flow opening 1.

[0044] Specifically, a guide structure 107 is provided on the side of each meshing tooth 102 near the gear 202. The guide structure 107 provides guidance for the meshing tooth 102 during the contact and meshing process with the gear 202, ensuring that the meshing tooth 102 makes smooth contact with the tooth surface of the gear 202, thereby improving the meshing accuracy between the two and reducing the meshing disorder caused by positional deviation. This ensures that the pusher 10 can stably and accurately drive the door panel 60 to seal the flow opening 1 during the movement. At the same time, the guide structure can reduce the direct impact between the meshing tooth 102 and the tooth surface of the gear 202. Especially in the initial meshing stage, the guide structure makes the meshing process smoother, reduces the wear between the meshing tooth 102 and the gear 202, effectively extends the service life of the gear 202 and the meshing tooth 102, and reduces the maintenance cost of the door panel drive mechanism.

[0045] In this embodiment, a positioning groove 302 is provided in the sliding member 30, and the shape of the positioning groove 302 is adapted to the shape of the push rod body 101; a support rib 103 is provided on the push rod body 101, the support rib 103 extends along a preset direction, and the support rib 103 abuts against the groove wall of the positioning groove 302.

[0046] Specifically, the push rod body 101 is slidably inserted into the positioning groove 302, allowing the push member 10 and the sliding member 30 to be connected in an adjustable position. By setting the support rib 103 to abut against the groove wall of the positioning groove 302, not only is the contact area between the push rod body 101 and the positioning groove 302 reduced, thus reducing the friction between the push rod body 101 and the positioning groove 302, allowing the push rod body 101 to enter or leave the positioning groove 302 more easily, but the support rib 103 also extends along a preset direction, which can limit the lateral displacement of the push rod body 101 during the movement, preventing the movement direction of the push member 10 from deviating from the preset direction.

[0047] In this embodiment, the door panel driving mechanism further includes an upper support structure 40 and a lower support structure 50. The upper support structure 40 covers the lower support structure 50. Both the upper support structure 40 and the lower support structure 50 are provided with arc-shaped sliding tracks 401. The sliding member 30 is provided with a roller 301, which is movably inserted into the arc-shaped sliding track 401. The extension direction of the arc-shaped sliding track 401 is parallel to the extension direction of the predetermined trajectory.

[0048] Specifically, the arc-shaped sliding tracks 401 on the upper support structure 40 and the lower support structure 50 provide a precise guiding path for the slider 30, effectively constraining the movement direction of the slider 30 and ensuring that the transmission assembly moves along a predetermined trajectory. The roller 301, movably inserted within the arc-shaped sliding track 401, not only reduces the frictional resistance of the slider 30 during sliding, ensuring the smoothness and stability of the slider 30's movement, but also constrains the sliding direction of both the roller 301 and the slider 30.

[0049] Specifically, the roller 301 is pressed against the middle position of the arc-shaped sliding track 401, that is, along the width direction of the arc-shaped sliding track 401, there is a rolling gap between the roller 301 and the two side walls of the arc-shaped sliding track 401, so as to ensure that the roller 301 can move in the arc-shaped sliding track 401 in a preset direction, and avoid the arc-shaped sliding track 401 from hindering the roller 301 from moving in the preset direction.

[0050] In this embodiment, both the upper support structure 40 and the lower support structure 50 are provided with limiting protrusions 402. The limiting protrusions 402 extend along the distribution direction of the upper support structure 40 and the lower support structure 50. The limiting protrusions 402 are connected to the edge of the arc-shaped sliding track 401 to limit the sliding member 30.

[0051] Specifically, the limiting protrusion 402 can effectively limit the movement range of the slider 30, ensuring that the roller 301 moves within the arc-shaped sliding track 401, preventing the roller 301 from leaving the arc-shaped sliding track 401, thereby ensuring that the slider 30 runs accurately on the predetermined arc-shaped trajectory, without excessive deviation or derailment, and thus ensuring that the door panel 60 can accurately open or close the flow opening 1, avoiding the phenomenon that the flow opening 1 cannot be fully opened or closed.

[0052] In this embodiment, the door panel driving mechanism further includes a second driving member 80, and the sliding member 30 includes a swing part 304 and a connecting part 305 connected to each other. The swing part 304 is provided with a positioning groove 302 and a guide groove 303, and a roller 301 is installed in the guide groove 303. The connecting part 305 is provided on the side of the swing part 304 away from the positioning groove 302, and the connecting part 305 is used to connect with the second driving member 80 so that the second driving member 80 drives the sliding member 30 to move.

[0053] Specifically, the swing part 304 is provided with a positioning groove 302 and a guide groove 303, so that the swing part 304 is connected to both the push rod body and the roller 301; the connecting part 305 is used to connect with the second driving member 80, so that the second driving member 80 can drive the sliding member 30 to move through the connecting part 305.

[0054] In this embodiment, there are two arc-shaped sliding tracks 401, which are distributed at intervals along a preset direction. The slider 30 is provided with two guide groove groups, which are provided one-to-one with the two arc-shaped sliding tracks 401. Each guide groove group includes two guide grooves 303, which are distributed at intervals along the extension direction of the arc-shaped sliding track 401.

[0055] Specifically, there are four rollers 301 and four guide grooves 303, with each guide groove 303 corresponding to one of the rollers 301. Two arc-shaped sliding tracks 401 are spaced apart along a preset direction, and the two guide grooves 303 of each guide groove group are spaced apart along the extension direction of the arc-shaped sliding track 401. The rollers 301 in the two guide grooves 303 of each guide groove group slide on the corresponding arc-shaped sliding track 401, so that each arc-shaped sliding track 401 constrains the sliding direction of the corresponding roller 301. The two arc-shaped sliding tracks 401 together provide a precise guide path for the slider 30, further effectively constraining the movement direction of the slider 30 and ensuring that the transmission component moves along a predetermined trajectory.

[0056] In this embodiment, a connecting groove 503 is provided on the lower support structure 50, the connecting groove 503 is used to install the second driving member 80, and a connecting sleeve 306 is provided on the connecting part 305, the connecting sleeve 306 is sleeved on the driving shaft 801 of the second driving member 80 and fixedly connected to the driving shaft 801.

[0057] Specifically, the connecting groove 503 on the lower support structure 50 provides installation space and stable support for the second drive member 80, ensuring the stability of the second drive member 80 during operation; the connecting sleeve 306 is sleeved on the drive shaft 801 of the second drive member 80 and fixedly connected to the drive shaft 801, ensuring that the connecting part 305 is drivenly connected to the second drive member 80, and ensuring that the second drive member 80 can drive the sliding member 30 to move.

[0058] Optionally, the first driving component 201 and the second driving component 80 are motors.

[0059] In this embodiment, the upper support structure 40 is provided with a clearance groove 403, and the first drive component 20 is provided on the side of the upper support structure 40 away from the lower support structure 50. The gear 202 of the first drive component 20 passes through the clearance groove 403.

[0060] Specifically, the upper support structure 40 is used to provide installation space and stable support for the first drive assembly 20. The gear 202 in the first drive assembly 20 can pass through the clearance groove 403, so that the gear 202 can smoothly mesh with the meshing teeth 102 on the sliding member 30 below the upper support structure 40.

[0061] In this embodiment, a door panel assembly part 601 is provided on the door panel 60, and the door panel assembly part 601 is fastened to the pusher 10; a positioning recess 602 is provided on the door panel assembly part 601, and a positioning protrusion 307 is provided on the sliding member 30. The shapes of the positioning recess 602 and the positioning protrusion 307 are adapted to each other, and the positioning recess 602 and the positioning protrusion 307 are detachably connected.

[0062] Specifically, the push rod body 101 is provided with a first fastening hole 504, and the door panel assembly part 601 is provided with a second fastening hole 505. Fasteners (screws) are passed through the first fastening hole 504 and the second fastening hole 505 to fasten the door panel assembly part 601 and the push member 10.

[0063] Specifically, by providing a door panel assembly part 601 on the door panel 60 and fastening it to the pusher 10, it is ensured that the pusher 10 can drive the door panel 60 to move along a preset direction so that the door panel 60 seals the flow opening 1. By detachably connecting the positioning recess 602 to the positioning protrusion 307, the door panel 60 and the sliding member 30 are detachably connected, ensuring that the transmission component is connected to the door panel 60. The transmission component can drive the door panel 60 to move along a predetermined trajectory so that the door panel 60 can close or open the flow opening 1. At the same time, by having the positioning recess 602 pass through the positioning protrusion 307, it helps to align the positioning between the door panel 60 and the sliding member 30, ensuring that the first fastening hole 504 is directly opposite the second fastening hole 505, thereby ensuring that the fastener (screw) can pass smoothly through the first fastening hole 504 and the second fastening hole 505.

[0064] This utility model also provides an air conditioner, including a door panel 60 and the aforementioned door panel drive mechanism.

[0065] The air conditioner of this utility model includes a door panel 60 and the aforementioned door panel driving mechanism. The door panel driving mechanism includes: a transmission assembly for connection to the door panel 60, the transmission assembly being movably disposed along a predetermined trajectory position to drive the door panel 60 to move relative to the flow opening 1 until it reaches an open or closed position; wherein, the transmission assembly includes a pusher 10 and a slider 30, the pusher 10 being connected to the door panel 60, and the pusher 10 and slider 30 being adjustablely connected so that when the transmission assembly drives the door panel 60 to the closed position, the pusher 10 and the door panel 60 move relative to the slider 30 in a predetermined direction to seal the flow opening 1.

[0066] like Figure 1 and Figure 2 As shown, the door panel driving mechanism of this utility model consists of a first driving assembly 20, a second driving member 80, a pushing member 10, a sliding member 30, a roller 301, an upper support structure 40, and a lower support structure 50. The air conditioner includes a door panel 60 and a door panel driving mechanism. The door panel 60 is driven to the closed position by the transmission assembly to close the flow opening 1. Then, the pushing member 10 and the door panel 60 move relative to the sliding member 30 in a preset direction to seal the flow opening 1. Even if the door panel 60 is tightly attached to the front panel 70, the door panel 60 and the inner wall of the front panel 70 are in sealed contact, avoiding a large gap between the door panel and the front panel 70 when the door panel is closed. Specifically, the first driving assembly 20 includes a first driving member 201, a gear 202, and a gear protective cover 203, with the gear protective cover 203 covering the gear 202.

[0067] The specific assembly process is as follows: First, assemble the second drive component 80 into the connecting groove 503 and tighten it with two motor fixing screws. Next, press and fix the four rollers 301 into the guide grooves 303 on the sliding component 30, and insert the push rod body 101 into the positioning groove 302. After installing the rollers 30 on the sliding component 30, fit the connecting sleeve 306 on the sliding component 30 onto the drive shaft 801 of the second drive component 80 and fix it to the drive shaft 801. Align the rollers 301 with the two arc-shaped sliding tracks 401 on the lower support structure 50. When assembling the support structure 40, first assemble the first drive component 201 into the drive component fixing part 405, cover the gear 202 with the gear protective cover 203, and tighten the gear protective cover 203 and the drive component fixing part 405 with two motor fixing screws. Three screws are passed through holes 407 and three screw posts 404. At this time, the two arc-shaped sliding tracks 401 on the upper support structure 40 will also press against the roller 301, ensuring that the roller 301 is pressed in the middle position of the arc-shaped sliding track 401. Finally, by passing three screws through the corresponding screw holes 407 and corresponding screw posts 404 in sequence, the fastening between the upper support structure 40 and the lower support structure 50 is completed. The positioning recess 602 on the door panel assembly part 601 at one end of the door panel 60 passes through the positioning protrusion 307, and then two screws pass through the first fastening hole 504 and the second fastening hole 505. Then, the positioning recess 602 on the door panel assembly part 601 at the other end of the door panel 60 passes through the positioning protrusion 307, and then two screws pass through the first fastening hole 504 and the second fastening hole 505, completing the connection between the door panel 60 and the door panel drive structure.

[0068] like Figure 3 As shown, the lower support structure 50 is provided with a connecting groove 503, two arc-shaped sliding tracks 401, two limiting protrusions 402 and three screw posts 404. The two limiting protrusions 402 and the two arc-shaped sliding tracks 401 are arranged in a one-to-one correspondence, and each limiting protrusion 402 is connected to the edge of the corresponding arc-shaped sliding track 401.

[0069] like Figure 4 As shown, the upper support structure 40 is provided with a drive component fixing part 405, a connecting sleeve fixing groove 406, two arc-shaped sliding tracks 401, two limiting protrusions 402 and three screw through holes 407. The two limiting protrusions 402 and the two arc-shaped sliding tracks 401 are arranged in a one-to-one correspondence, and each limiting protrusion 402 is connected to the edge of the corresponding arc-shaped sliding track 401.

[0070] In practice, three screw through holes 407 and three screw posts 404 are set one-to-one. By passing the screws through each screw through hole 407 and the corresponding screw post 404, the upper support structure 40 and the lower support structure 50 are securely connected. This three-point fixing method significantly enhances the rigidity and stability of the entire door panel drive mechanism, reduces the vibration and noise of the door panel 60 during movement, ensures the smooth operation of the door panel 60 and the precise sealing in the closed state, and improves the user experience of the air conditioner. At the same time, the insertion connection between the screw through holes 407 and the screw posts 404 eliminates the need for complex alignment or adjustment steps during assembly. The screws only need to be passed through the corresponding screw through holes 407 and corresponding screw posts 404 in sequence to complete the fastening, which greatly shortens the assembly time of the door panel drive mechanism, reduces the production cost of the door panel drive mechanism, helps to avoid assembly errors, and thus improves the production efficiency and product quality of the air conditioner.

[0071] In specific implementation, the connecting sleeve fixing groove 406 on the upper support structure 40 is used for the connecting sleeve 306 to pass through. Through the limiting effect of the connecting sleeve fixing groove 406 on the connecting sleeve 306, the door panel drive mechanism can keep the connecting sleeve 306 sleeved on the drive shaft 801 of the second drive member 80 and fixedly connected to the drive shaft 801 even after long-term operation. This avoids the connection between the connecting sleeve 306 and the drive shaft 801 becoming loose or even separating from the drive shaft 801, which would lead to transmission failure or a decrease in transmission efficiency between the connecting part 305 and the second drive member 80, thus ensuring the long-term reliable operation of the door panel drive mechanism.

[0072] like Figure 5 , Figure 6 , Figure 7 As shown, the sliding member 30 is provided with a swing part 304 and a connecting part 305. The swing part 304 is provided with a positioning groove 302 and four guide grooves 303. The push rod body 101 is provided with multiple meshing teeth 102, support ribs 103, two positioning protrusions 307 and two first fastening holes 504.

[0073] like Figure 8 and Figure 9 As shown, a door panel assembly part 601 is provided at each end of the door panel 60. The door panel assembly part 601 is provided with two second fastening holes 505 and two positioning recesses 602. The positioning recesses 602 are detachably connected to the positioning protrusions 307, so that the door panel 60 and the sliding member 30 are detachably connected, ensuring the connection between the transmission component and the door panel 60. Fasteners (screws) are passed through the first fastening holes 504 and the second fastening holes 505, so that the door panel assembly part 601 and the pusher 10 are fastened together.

[0074] like Figure 10As shown, during the operation of the door panel drive mechanism, the sliding member 30 is driven to move by the second drive member 80, so that the roller 301 rolls back and forth in the arc-shaped sliding track 401 along the extension direction of the arc-shaped sliding track 401. When the sliding member 30 moves to the position, it will be blocked by the limiting protrusion 402, which together with the second drive member 80 locks the sliding member 30.

[0075] like Figure 11 As shown, when the door panel 60 closes the flow opening 1, the second driving member 80 first drives the sliding member 30 to rotate clockwise around the axis of the driving shaft 801, causing the door panel 60 to move relative to the flow opening 1 until it reaches the closed position. The push rod body 101 is provided with multiple meshing teeth 102 that mesh smoothly with the gear 202. Then, the first driving member 201 drives the gear 202 to rotate around the axis of the gear 202, so that the gear 202 drives the push member to move in a preset direction toward the flow opening 1, so that the door panel 60 seals the flow opening 1.

[0076] like Figure 12 As shown, when the door panel 60 opens the flow opening 1, the first driving member 201 drives the gear 202 to rotate around the axis of the gear 202, causing the gear 202 to drive the pushing member to move in a preset direction away from the flow opening 1, thereby making the door panel 60 leave the flow opening 1 and free up sufficient space. Then, the second driving member 80 drives the sliding member 30 to rotate counterclockwise around the axis of the driving shaft 801, causing the door panel 60 to move relative to the flow opening 1 until it moves to the open position.

[0077] like Figure 13 and Figure 14 As shown, before the door panel 60 moves along the preset direction, there is a gap of about 5mm between the door panel 60 and the front panel 70, which may allow cockroaches and dust to enter, and at the same time, the step-like appearance is obvious, affecting the appearance. After the door panel 60 moves along the preset direction, the gap between the door panel 60 and the front panel 70 can be reduced to 0-0.5mm, which is visually almost seamless and has an aesthetically pleasing appearance.

[0078] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0079] The door panel driving mechanism of this utility model includes a transmission assembly, which includes a pusher 10 and a slider 30. The pusher 10 is used to connect with the door panel 60. The pusher 10 and the slider 30 are connected in an adjustable position. The transmission assembly drives the door panel 60 to move to the closed position to close the flow opening 1. Then, the pusher 10 and the door panel 60 move relative to the slider 30 in a preset direction to seal the flow opening 1. Even if the door panel 60 is tightly attached to the front panel 70, the door panel 60 and the inner wall of the front panel 70 are in sealed contact, avoiding a large gap between the door panel and the front panel 70 when the door panel is closed. This solves the problem of a large gap between the air conditioner sliding door panel and the front panel 70 when closed in the prior art, preventing dust, cockroaches, etc. from entering the air conditioner from the gap, while ensuring the overall appearance of the air conditioner.

[0080] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0081] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing parts. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0082] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
