Description

Technical Field

[0001] This application belongs to the technical field of household appliances, specifically relating to an unlockable locking mechanism and an air conditioner. Background Technology

[0002] Taking air conditioners as an example, air conditioners contain purification modules, such as those with dust removal and sterilization functions, installed through a locking mechanism with an unlocking function. These purification modules need to be disassembled for cleaning or maintenance periodically. Air conditioners vibrate during operation, and to reinforce the connection between the purification module and the air conditioner, the locking mechanism is usually not easy to unlock, making the disassembly process of the purification module quite cumbersome.

[0003] For locking mechanisms that rely on the deformation of structural components, such as latches, they generally also function as unlocking mechanisms. They use the opposite direction of movement to locking, and unlocking is achieved through the deformation of the locking mechanism itself.

[0004] However, because this locking structure also allows for unlocking, its locking stability is unreliable and it is not suitable for situations where unlocking is frequent. How to make the locking mechanism both stable and secure in locking and easy to unlock has become an urgent problem to be solved. Summary of the Invention

[0005] In order to solve the above-mentioned problems in the prior art, that is, to achieve a locking mechanism that can lock stably and securely while also being easy to unlock, this application provides an unlockable locking mechanism and an air conditioner.

[0006] This application provides an unlockable locking mechanism, including a housing and at least one support frame, wherein the support frame is capable of locking with the housing.

[0007] The housing is provided with a deformable spring piece; the support frame is provided with a positioning locking post, which can tightly abut against the spring piece and deform the spring piece. When the support frame and the housing are locked together, the spring piece tightly abuts against the positioning locking post to limit the positioning locking post.

[0008] The support frame is connected to an unlocking key, which can abut against the spring and disengage the spring from the positioning locking post.

[0009] In the preferred embodiment of the unlockable locking mechanism described above, the housing is provided with a guide groove, which is used to accommodate and guide the positioning locking pin.

[0010] In the preferred embodiment of the unlockable locking mechanism described above, the spring is inclined and extends towards the inside of the housing, gradually approaching the guide groove.

[0011] In the preferred embodiment of the unlockable locking mechanism described above, the end of the spring piece used to limit the positioning locking pin is provided with a positioning arc groove, and the positioning locking pin can fit tightly with the positioning arc groove.

[0012] In the preferred embodiment of the unlockable locking mechanism described above, the support frame is provided with a connecting positioning post for connecting the unlocking key, the unlocking key is sleeved on the connecting positioning post, and the unlocking key and the connecting positioning post are rotatably engaged.

[0013] In the preferred embodiment of the unlockable locking mechanism described above, the unlocking key has a slot at the part that cooperates with the connecting positioning post, and this part of the unlocking key is deformable and elastic, allowing the connecting positioning post to pass through the slot.

[0014] In the preferred embodiment of the above-mentioned unlockable locking mechanism, the unlocking key includes a rotating plate and a top plate;

[0015] The rotating plate is provided with a buckle, and the support frame is provided with a fastening part for engaging with the buckle;

[0016] The top plate is used to abut against the spring and deform it.

[0017] In the preferred embodiment of the unlockable locking mechanism described above, the top plate is arc-shaped, and the concave surface of the top plate corresponds to the spring piece.

[0018] In the preferred embodiment of the unlockable locking mechanism described above, a reinforcing rib is connected between the rotating plate and the top plate.

[0019] This application embodiment also provides an air conditioner, including an indoor unit and an outdoor unit connected to each other, wherein the indoor unit is equipped with the aforementioned unlockable locking mechanism.

[0020] Those skilled in the art will understand that the embodiments of this application provide an unlockable locking mechanism, including a housing and at least one support frame, the support frame being able to lock into the housing; the housing is provided with a deformable spring piece; the support frame is provided with a positioning locking pin, the positioning locking pin being able to tightly abut against the spring piece and deform the spring piece, when the support frame and the housing are locked into each other, the spring piece tightly abuts against the positioning locking pin to limit the positioning locking pin; the support frame is connected to an unlocking key, the unlocking key being able to abut against the spring piece and disengage the spring piece from the positioning locking pin.

[0021] By adopting the above technical solution, the support frame is used to install the purification module mentioned in the background technology. When assembling the support frame carrying the purification module with the housing, the positioning locking pin tightly abuts against the spring and the spring continuously deforms. After the support frame is assembled in place, the spring returns to its initial shape. At this time, the operator can hear a sound of the spring resetting. This sound serves as a prompt to indicate that the assembly of the support frame is complete. The spring and the housing can jointly and tightly abut against the positioning locking pin and completely limit the position of the positioning locking pin, thus achieving the locking of the support frame. Since the support frame itself is not deformable, the locked support frame cannot be unlocked by itself, so that the support frame can be stably and firmly locked, achieving a stable connection between the support frame and the housing, that is, achieving a stable connection between the purification module and the housing. When disassembling the purification module and the support frame, the unlocking key is used to continuously press against the spring clip, causing it to disengage from the positioning locking pin. The spring clip deforms to the unlocked position, at which point the support frame is unlocked. The support frame, along with the purification module, can then be gradually removed from the housing. The spring clip deformed to the unlocked position makes room for the disassembly of the positioning locking pin. After the support frame and purification module are completely removed from the housing, the spring clip returns to its initial shape, ready for the next assembly of the support frame. The unlockable locking mechanism provided in this application, after installation, allows the support frame with the unlocking key to lock into place with the housing. The locked support frame cannot be unlocked by itself, ensuring a stable and secure lock, thus achieving a stable and secure installation of the purification module. Unlocking is only possible by using the unlocking key, allowing for the separation of the support frame from the housing. This facilitates easy unlocking and quick disassembly of the purification module, while also enabling convenient replacement of the purification module.

[0022] This application also provides an air conditioner, including an indoor unit and an outdoor unit connected to each other, wherein the indoor unit is equipped with the aforementioned unlockable locking mechanism.

[0023] By adopting the above technical solution, the housing in the locking mechanism is installed on the indoor unit of the air conditioner. When assembling the purification module, the purification module is connected to the support frame. The support frame carrying the purification module is then assembled with the housing, causing the positioning locking pin to tightly abut against the spring and deform the spring. After assembly, the spring returns to its original position, and the spring and housing together tightly abut against the positioning locking pin, limiting its movement and achieving the locking of the support frame, thus ensuring the stable assembly of the purification module to the indoor unit of the air conditioner. When replacing the purification module on the indoor unit of the air conditioner, the buckle is pulled away from the fastening part to disengage it. The unlocking key is then rotated using a rotating plate, causing the top plate to apply force to the spring, gradually deforming it until the spring completely disengages from the positioning locking pin, thus unlocking the support frame. The support frame, along with the purification module, can then be removed from the indoor unit of the air conditioner. The air conditioner provided in this application, after installation, has a support frame with an unlocking button that can lock together with the housing installed on the indoor unit. The locked support frame cannot be unlocked by itself, ensuring that the support frame is stably and securely locked, thereby achieving a stable and secure installation of the purification module. When unlocking, the support frame can only be unlocked by using the unlocking button, enabling the support frame to be disassembled and separated from the indoor unit, achieving the effect of convenient unlocking, simple and quick disassembly of the purification module, and convenient replacement of the purification module.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0035] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0036] As mentioned in the background section, taking an air conditioner as an example, an air purification module, such as a dust removal and sterilization module, is installed inside the air conditioner via a locking mechanism with an unlocking function. The purification module needs to be disassembled for cleaning or maintenance periodically. The air conditioner vibrates during operation, and in order to reinforce the connection between the purification module and the air conditioner, the locking mechanism is usually not easy to unlock, making the disassembly process of the purification module quite cumbersome.

[0037] For locking mechanisms that rely on structural component deformation, such as the 311 buckle, the locking stability is unreliable because it also unlocks, and it is not suitable for situations where unlocking is frequent. How to make the locking mechanism both stably and firmly lock the purification module, ensuring stable and secure installation of the purification module, and also easily unlock the locking mechanism, allowing for simple and quick disassembly of the purification module, has become an urgent problem to be solved.

[0038] Therefore, in order to solve the above-mentioned technical problems, this application provides an unlockable locking mechanism and an air conditioner. After installation, the support frame 200 with the unlocking key 300 can lock with the housing 100. The locked support frame 200 cannot be unlocked by itself, so that the support frame 200 can be locked stably and firmly, thereby realizing the stable and firm installation of the purification module. When unlocking, the support frame 200 can only be unlocked by using the unlocking key 300, realizing the disassembly and separation of the support frame 200 from the housing 100, realizing the effect of convenient unlocking, the effect of simple and quick disassembly of the purification module, and the effect of convenient replacement of the purification module.

[0039] Please refer to Figure 1 and Figure 2 This application provides an unlockable locking mechanism, including a housing 100 and at least one support frame 200. The support frame 200 can be locked to the housing 100. The housing 100 is provided with a deformable spring piece 110. The support frame 200 is provided with a positioning locking pin 210, which can tightly abut against the spring piece 110 and deform the spring piece 110. When the support frame 200 and the housing 100 are locked to each other, the spring piece 110 and the housing 100 can jointly and tightly abut against the positioning locking pin 210 to limit the positioning locking pin 210. The support frame 200 is connected to an unlocking key 300, which can tightly abut against the spring piece 110 and disengage the spring piece 110 from the positioning locking pin 210.

[0040] By adopting the above technical solution, the support frame 200 is used to install the purification module mentioned in the background technology. When the support frame 200 carrying the purification module is assembled with the housing 100, the positioning locking pin 210 tightly abuts against the spring piece 110 and the spring piece 110 is continuously deformed. After the support frame 200 is assembled in place, the spring piece 110 returns to its initial shape. At this time, the operator can hear a sound of the spring piece 110 resetting. This sound serves as a prompt to indicate that the assembly of the support frame 200 is complete. The spring piece 110 and the housing 100 can jointly and tightly abut against the positioning locking pin 210 and completely limit the position of the positioning locking pin 210, thus achieving the locking of the support frame 200. Since the support frame 200 itself is not deformable, the locked support frame 200 cannot be unlocked by itself, so that the support frame 200 can be stably and firmly locked, achieving a stable connection between the support frame 200 and the housing 100, that is, achieving a stable connection between the purification module and the housing 100. When disassembling the purification module and the support frame 200, the unlock button 300 is used to continuously press against the spring piece 110 and disengage the spring piece 110 from the positioning locking post 210. The spring piece 110 deforms to the unlock position. At this time, the support frame 200 is unlocked, and the support frame 200 and the purification module can be gradually removed from the housing 100. The spring piece 110 deformed to the unlock position makes room for the disassembly of the positioning locking post 210. After the support frame 200 and the purification module are completely removed from the housing 100, the spring piece 110 returns to its initial shape and waits for the next assembly of the support frame 200.

[0041] The unlockable locking mechanism provided in this application, after installation, allows the carrier frame 200 with the unlocking key 300 to lock into the housing 100. The locked carrier frame 200 cannot be unlocked by itself, ensuring that the carrier frame 200 is stably and securely locked, thereby achieving stable and secure installation of the purification module. When unlocking, the carrier frame 200 can only be unlocked by using the unlocking key 300, enabling the carrier frame 200 to be disassembled and separated from the housing 100. This achieves the effect of convenient unlocking, simple and quick disassembly of the purification module, and convenient replacement of the purification module.

[0042] Please refer to Figure 1 and Figure 2 In this embodiment of the application, for example, the unlockable locking mechanism can be located on one side of the support frame 200 or on both sides of the support frame 200 that are far apart from each other. The housing 100 is provided with a spring piece 110 that cooperates with the positioning locking post 210 at the corresponding positioning locking post 210.

[0043] By adopting the above technical solution, a single locking mechanism on one side of the support frame 200 can achieve a stable connection between the support frame 200 and the housing 100. Compared with the case of setting a single locking mechanism, the case of setting two locking mechanisms on both sides of the support frame 200 that are far apart from each other can achieve a more stable connection and installation between the support frame 200 and the housing 100. This allows the support frame 200 to more stably assemble the purification module with the housing 100, and the support frame 200 to provide more stable support and load for the purification module. During the operation of the air conditioner, the vibration that may occur in the support frame 200 is reduced.

[0044] Please refer to Figure 2 In this embodiment of the application, for example, the housing 100 has a guide groove 120 at the assembly position of the corresponding positioning locking post 210. The guide groove 120 is used to accommodate and guide the limiting positioning locking post 210. In the direction away from the interior of the housing 100, the guide groove 120 is flared.

[0045] By adopting the above technical solution, the guide groove 120 becomes the moving space for the positioning locking post 210. The guide groove 120 can accommodate and guide and limit the positioning locking post 210, making the assembly of the support frame 200 more convenient, precise, and efficient. In the direction away from the interior of the housing 100, because the guide groove 120 is flared, during the initial assembly of the positioning locking post 210, it is sufficient to roughly align the positioning locking post 210 with the opening of the guide groove 120. As the positioning locking post 210 is gradually assembled into the deepest part of the guide groove 120, it can be guided by the guide groove 120 to the designed assembly position. The flared shape of the guide groove 120 facilitates the rapid assembly of the positioning locking post 210, which in turn facilitates the rapid assembly of the support frame 200 and the purification module.

[0046] Please refer to Figure 2In this embodiment of the application, for example, there are various ways to connect the spring 110 and the housing 100, such as welding, fusion or integral molding. In this embodiment, integral molding is preferred. Since the spring 110 and the housing 100 are manufactured by integral molding, that is, the spring 110 and the housing 100 are a whole, the structural strength of the connection part of the spring 110 and the housing 100 is maximized, which can extend the service life of the spring 110 and avoid cracking and damage of the spring 110. For example, the spring piece 110 is inclined and gradually approaches the guide groove 120 in the direction of extending into the housing 100. If two spring pieces 110 are provided in the same position in the housing 100, the two spring pieces 110 have an included angle. That is, in the direction of extending into the housing 100, the two spring pieces 110 gradually move away from each other. The end of the spring piece 110 used to limit the positioning locking post 210 is provided with a positioning arc groove. After the positioning locking post 210 is engaged in the locking position, the positioning locking post 210 can fit tightly with the concave surface of the positioning arc groove.

[0047] By adopting the above technical solution, due to the inclined setting of the spring piece 110, during the assembly of the support frame 200, the force exerted by the spring piece 110 on the positioning locking post 210 gradually increases, and the spring piece 110 gradually enters the guide groove 120 to guide the positioning locking post 210. After the support frame 200 is assembled in place, the spring piece 110 immediately returns to its initial shape. At this time, the operator can hear a sound of the spring piece 110 resetting. This sound serves as a prompt to indicate that the assembly of the support frame 200 is complete. The concave surface of the positioning arc groove of the spring piece 110 can fit tightly with the positioning locking post 210, increasing the contact area between the spring piece 110 and the positioning locking post 210, increasing the contact stability between the spring piece 110 and the positioning locking post 210, and making the locking of the support frame 200 more stable.

[0048] Please refer to Figure 3 In this embodiment, for example, the support frame 200 is provided with a connecting positioning post 220 for connecting the unlocking key 300 at the position for mounting the unlocking key 300. For example, the connection method between the connecting positioning post 220 and the support frame 200 can be various, such as welding, fusion, or integral molding. This embodiment preferably uses integral molding. Since the connecting positioning post 220 and the support frame 200 are manufactured as an integral piece, the connection strength between the connecting positioning post 220 and the support frame 200 is maximized. For example, the corresponding assembly part of the unlocking key 300 is fitted with the connecting positioning post 220, and the unlocking key 300 and the connecting positioning post 220 are rotatably engaged. For example, the unlocking key 300 has a slot 330 at the part that mates with the connecting positioning post 220, and the slot 330 of the unlocking key 300 is deformable and elastic, allowing the connecting positioning post 220 to pass through the slot 330.

[0049] By adopting the above technical solution, when the unlocking key 300 does not have a latch 330, the unlocking key 300 and the connecting positioning post 220 are rotatably connected, making the connection between the unlocking key 300 and the connecting positioning post 220 more stable. When the unlocking key 300 has a latch 330, aligning the latch 330 with the connecting positioning post 220 and pressing the unlocking key 300 firmly will quickly connect the unlocking key 300 and the connecting positioning post 220. Pulling the unlocking key 300 forcefully away from the connecting positioning post 220 will disassemble the unlocking key 300. The unlocking key 300 and the connecting positioning post 220 are detachably connected, which has the advantage of facilitating the replacement of a new unlocking key 300.

[0050] Please refer to Figure 3 In this embodiment of the application, for example, the unlock key 300 includes a rotating plate 310 and a top plate 320. For example, the rotating plate 310 may be perpendicular to the top plate 320, or the rotating plate 310 and the top plate 320 may form an obtuse angle with each other. However, in any case, the end of the top plate 320 away from the rotating plate 310 extends in the direction of the spring piece 110. A buckle 311 is provided on one side of the rotating plate 310. The buckle 311 is deformable and elastic. For example, the buckle 311 and the rotating plate 310 can be connected in various ways, such as welding, fusion or integral molding. In this embodiment, integral molding is preferred. Since the buckle 311 and the rotating plate 310 are manufactured by integral molding, the structural strength of the connection between the buckle 311 and the rotating plate 310 is maximized. The support frame 200 is provided with a fastening part 230 for engaging with the buckle 311. The top plate 320 is used to abut against the spring piece 110 and deform the spring piece 110. The top plate 320 is set in an arc shape. When the buckle 311 of the unlocking key 300 is engaged with the fastening part 230 on the support frame 200, the unlocking key 300 is in the locked position. The concave surface of the top plate 320 corresponds to the spring piece 110.

[0051] By adopting the above technical solution, when the unlock button 300 is not in use, the latching part 230 and the buckle 311 are kept in a locked engagement, which can maintain the stable positioning of the unlock button 300, prevent the unlock button 300 from vibrating or moving, and improve the quietness of the air conditioner. When the unlocking key 300 is needed to unlock the carrier frame 200, the buckle 311 is pulled away from the fastening part 230 to disengage the buckle 311 from the fastening part 230. The unlocking key 300 is then rotated using the rotating plate 310, causing the top plate 320 to apply force to the spring piece 110, gradually deforming the spring piece 110 until the spring piece 110 is completely disengaged from the positioning locking pin 210, thus unlocking the carrier frame 200. After the unlocking key 300 is rotated to unlock, it can be used as a handle for easy carrying of the carrier frame 200. Since the top plate 320 is curved, when the top plate 320 applies force to the spring piece 110, the direction of the force applied by the top plate 320 to the spring piece 110 is closer to the normal direction of the spring piece 110, resulting in greater, more stable, and more uniform force on the spring piece 110.

[0052] Please refer to Figure 2 and Figure 3 In this embodiment, for example, at least one reinforcing rib 340 is connected between the rotating plate 310 and the top plate 320. This embodiment shows two reinforcing ribs 340 facing each other. The outer surfaces of the two reinforcing ribs 340 facing away from each other are flush with the outer surfaces of the top plate 320 and the rotating plate 310. For example, the reinforcing ribs 340 can be connected to the rotating plate 310 and the top plate 320 in various ways, such as welding, fusion, or integral molding. In this embodiment, integral molding is preferred. Since the rotating plate 310, the top plate 320, and the reinforcing ribs 340 are manufactured as a single unit, the entire component of the unlocking key 300 is a single unit, which maximizes the structural strength of the unlocking key 300 and extends its service life.

[0053] By adopting the above technical solution, the two reinforcing ribs 340 connect the rotating plate 310 and the top plate 320 into one unit, which improves the structural strength of the unlocking key 300, enhances the overall structural stability of the unlocking key 300, and extends the service life of the unlocking key 300.

[0054] In summary, during the assembly of the purification module, the purification module is connected to the support frame 200. The support frame 200 carrying the purification module is then assembled with the housing 100, causing the positioning locking pin 210 to tightly abut against the spring piece 110 and deform it. After assembly, the spring piece 110 returns to its original position, and the spring piece 110 and the housing 100 together tightly abut against the positioning locking pin 210 and limit its movement, thus locking the support frame 200 and ensuring the stable assembly of the purification module. When replacing the purification module, the buckle 311 is moved away from the fastening part 230, causing it to disengage. The unlocking key 300 is then rotated using the rotating plate 310, causing the top plate 320 to apply force to the spring piece 110, gradually deforming it until it completely disengages from the positioning locking pin 210, thus unlocking the support frame 200. The support frame 200, along with the purification module, can then be removed from the housing 100. After the unlock button 300 is rotated to unlock, it can be used as a handle to facilitate carrying the carrier 200.

[0055] This application also provides an air conditioner, including an indoor unit and an outdoor unit connected to each other, wherein the indoor unit is equipped with the aforementioned unlockable locking mechanism.

[0056] By adopting the above technical solution, the housing 100 in the locking mechanism is installed on the indoor unit of the air conditioner. When assembling the purification module, the purification module is connected to the support frame 200. The support frame 200 carrying the purification module is assembled with the housing 100, so that the positioning locking pin 210 tightly abuts against the spring piece 110 and deforms the spring piece 110. After assembly, the spring piece 110 returns to its original position. The spring piece 110 and the housing 100 together tightly abut against the positioning locking pin 210 and limit the positioning locking pin 210, thereby achieving the locking of the support frame 200, that is, achieving the stable assembly of the purification module to the indoor unit of the air conditioner. When replacing the purification module on the indoor unit of the air conditioner, move the latch 311 away from the latching part 230 to disengage it. Then, rotate the unlocking key 300 using the rotating plate 310. This causes the top plate 320 to apply force to the spring piece 110, gradually deforming it until it completely disengages from the positioning locking pin 210. This unlocks the support frame 200, allowing it to be removed from the indoor unit along with the purification module. After unlocking, the unlocking key 300 can be used as a handle for easy carrying of the support frame 200.
