Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a housing structure, a remote control, and a household appliance. Background Technology

[0002] With the increasing popularity of electronic products in homes, remote controls, as one of the most common electronic devices, often use button batteries as their power source.

[0003] Existing safety standards (such as GB 4706 / IEC 60335, GB 4943 / IEC 62368, UL 4200A) require that the battery compartment cover must be opened with a tool or that at least two independent and synchronized actions must be applied to open it manually. However, most existing remote control battery compartment covers are secured with simple screws or clips, which presents the following problems: 1. The battery compartment cover is easy to open with children's bare hands, and the small size and round shape of button batteries pose a safety hazard of being swallowed or inhaled. 2. Traditional designs rely heavily on screws for fixing, which increases production costs and assembly complexity. Some single-fixation buckle designs do not meet safety standards.

[0004] Therefore, there is an urgent need for a battery compartment structure that meets international safety standards, is easy for users to operate, and does not require the use of screws. Utility Model Content

[0005] In view of this, the present invention provides a housing structure, a remote control and a household appliance to solve the problem that children can easily open the battery compartment cover to remove the button battery, which poses a significant safety hazard.

[0006] In a first aspect, this utility model provides a shell structure, comprising: Battery compartment; The first housing has a mounting hole that communicates with the battery compartment; the end face of the first housing near the battery compartment is provided with a first connecting structure and a locking part; The cover is rotatably disposed at the mounting hole to close the battery compartment; a second connecting structure is provided on the end face of the cover near the battery compartment; the cover is provided with an anti-dislodgement hole adapted to the locking part; The cover has a locked state and an unlocked state; when the second connecting structure is matched and connected with the first connecting structure, and the end of the locking part is engaged in the anti-disengagement hole, the cover is in the locked state; when a force is applied to the locking part along the axial direction of the housing structure, the locking part moves along the axial direction of the housing structure and can squeeze and apply a circumferential force to the cover, the locking part disengages from the anti-disengagement hole and the second connecting structure disengages from the first connecting structure, so that the cover is in the unlocked state.

[0007] Beneficial effects: During installation, rotating the cover causes the second connecting structure on the cover to slide into the first connecting structure on the first housing, and the locking part on the first housing engages with the anti-disengagement hole on the cover, forming a locked state. To open, a tool is used to axially press the locking part in the anti-disengagement hole to disengage the locking part, and then the cover is rotated circumferentially to disengage the first connecting structure from the second connecting structure, thus unlocking the cover. Opening the cover requires a tool to press the locking part to open the cover and remove the battery. Unlocking the cover by hand without a tool is not feasible for young children with limited cognitive abilities who do not understand the logical connection between tools and opening the housing. Therefore, children are less likely to open the cover corresponding to the battery compartment, avoiding the need to remove the button battery from the battery compartment, effectively improving safety.

[0008] In one optional embodiment, the locking part includes: An elastic arm is provided to extend circumferentially along the first housing; A contact is disposed at the end of the elastic arm; in the locked state, the contact is engaged in the anti-disengagement hole and the contact at least circumferentially limits the cover.

[0009] Beneficial Effects: The elastic arm provides a certain amount of elastic force during locking and unlocking. When the cover rotates to the locked position, the elastic force of the arm allows the contact to be more tightly engaged in the anti-disengagement hole, enhancing the reliability of the lock. The contact, engaged in the anti-disengagement hole, provides circumferential restraint to the cover, ensuring locking reliability. When unlocking is required, pressing the locking part in the anti-disengagement hole axially with a tool causes the elastic arm to deform elastically, allowing the contact to disengage from the anti-disengagement hole. Simultaneously, during axial movement, the elastic arm effectively transmits external force to the cover, compressing and applying circumferential force to the cover, helping it to more easily disengage from the first connecting structure, thus unlocking. This design makes unlocking easier and less strenuous, eliminating the need for additional complex mechanisms for force conversion and transmission. The combination of the elastic arm and contact is simple and compact, easy to manufacture and assemble, and also improves the reliability and stability of the entire locking mechanism. Compared to some complex locking mechanisms, this structure reduces the number of parts, lowering the probability of locking failure due to component damage. Furthermore, the elastic arm maintains relatively stable elasticity over long-term use, ensuring proper locking and unlocking. The presence of the elastic arm and contacts makes the cover lock more secure, making it more difficult for children to open it by hand. Overcoming the elastic force of the arm and the clamping force of the contacts requires tools and strength, posing a significant obstacle for children with limited cognitive and physical abilities, thus further enhancing safety by preventing children from accidentally opening the battery compartment or accessing the button batteries.

[0010] In one alternative embodiment, in the locked state, the top surface of the contact is lower than the top surface of the cover.

[0011] Beneficial effects: The top surface of the contact is lower than the top surface of the cover, preventing accidental axial movement of the contact during normal use. This avoids the locking part from disengaging from the anti-disengagement hole, preventing accidental unlocking of the cover and maintaining the stability of the locked state. For children, because the contact is hidden below the top surface of the cover, it is more difficult to unlock the cover by directly pressing or flicking the contact. This further increases the difficulty for children to open the cover, thus better protecting children and avoiding potential dangers from small parts such as button batteries.

[0012] In one optional implementation, the second connection structure includes: At least two of the swivels are distributed circumferentially along the first housing.

[0013] Beneficial effects: Multiple circumferentially distributed knobs provide connection force from multiple angles when the cover is connected to the first housing, making the connection between the cover and the first housing more stable. Compared to a single connection structure, multiple knobs can evenly distribute the force, avoiding loosening due to excessive local force, ensuring that the battery compartment will not easily open during normal use, thus improving the safety and reliability of the device. During installation, simply rotate the cover to allow the knobs to slide and engage with the corresponding structures on the first housing to complete the connection; axial limiting operation is relatively simple and convenient. During disassembly, after releasing the lock, rotate the cover in the opposite direction to detach the knobs from the first housing; no complicated operation steps are required. The connection of multiple knobs to the first housing increases the contact area and the number of connection points between the cover and the first housing, thereby improving the strength and rigidity of the entire housing structure and making it less prone to damage. The connection and cooperation between the knobs and the first housing allows for better coordination with the locking mechanism to achieve locking and unlocking functions. In the locked state, the thimble engages tightly with the first connecting structure to prevent the cover from rotating; when unlocking, by operating the locking part, the thimble can smoothly disengage from the first connecting structure, thus opening the cover. This design makes the locking and unlocking process more reliable and smooth.

[0014] In one optional implementation, the first connection structure includes: The limiting buckle, at least two of which are distributed circumferentially along the cover; when the swivel buckle slides into the limiting buckle, the limiting buckle at least axially limits the cover.

[0015] Beneficial Effects: When the swivel buckle slides into the limiting buckle, the limiting buckle axially limits the cover, preventing it from moving in the axial direction and ensuring a more secure connection between the cover and the first housing. This effectively prevents the battery compartment from opening due to axial movement of the cover during normal use, avoiding battery detachment or other safety issues. Multiple limiting buckles are distributed circumferentially, limiting and fixing the cover from multiple angles, making the connection between the cover and the first housing more stable and reliable. Compared to a single limiting structure, multiple limiting buckles can evenly distribute the force, preventing loosening due to excessive local force and improving the strength and stability of the entire housing structure. Installation is simple: align the swivel buckle on the cover with the limiting buckle on the first housing, then rotate the cover to slide the swivel buckle into the limiting buckle. Disassembly is straightforward: after releasing the lock, rotate the cover in the opposite direction to disengage the swivel buckle from the limiting buckle. No complicated steps are required, facilitating battery replacement and other maintenance operations. The limiting buckle and the locking part can work together more effectively to achieve the locking and unlocking functions of the cover. In the locked state, the limiting buckle axially limits the cover, while the locking part circumferentially limits it. The two work together to firmly fix the cover to the first housing. When unlocking, by operating the locking part, the locking part is disengaged from the anti-disengagement hole, and the buckle can also be smoothly disengaged from the limiting buckle, thus opening the cover. This makes the locking and unlocking process more reliable and smooth.

[0016] In one alternative embodiment, the second connection structure includes at least one snap fastener, wherein one of the snap fasteners is located near the anti-disengagement hole, and the snap fastener near the anti-disengagement hole is provided with a guide bevel.

[0017] Beneficial effect: The guide slope is set on the buckle near the anti-disengagement buckle, which makes it easy to apply force directly to the guide slope when the locking part moves away from the cover. This causes the locking part to disengage from the anti-disengagement hole while pushing the cover to move a certain distance in a circumferential direction, thus preventing the locking part from returning to the anti-disengagement hole during the rebound process.

[0018] In one alternative embodiment, the projection of the anti-detachment hole is at least partially located on the guide ramp along the axial direction of the housing structure, such that the contact can compress and push the guide ramp as it moves away from the cover.

[0019] Beneficial effects: When unlocking is required, the contact moves away from the cover and presses against the guide ramp. Because the anti-disengagement hole is projected onto the guide ramp, the contact's force acts more precisely on it. A component force applied to the guide ramp effectively propels the cover circumferentially. This process reduces potential jamming or resistance during unlocking, ensuring smooth operation and facilitating easy opening of the cover. The anti-disengagement hole's projection on the guide ramp ensures the contact maintains good contact and interaction with the guide ramp as it moves away from the cover, preventing unlocking failures due to misalignment between the contact and the guide ramp. The contact's pressure against the guide ramp makes the circumferential movement of the cover more accurate, better preventing the locking part from returning to the anti-disengagement hole during rebound. Because the anti-disengagement hole's projection is on the guide ramp, the contact's force direction is more conducive to generating sufficient circumferential displacement of the cover, completely misaligning the locking part with the anti-disengagement hole, effectively preventing the locking part from rebounding and ensuring the stability of the unlocked state.

[0020] In one alternative embodiment, the guide ramp has an extension on the side away from the anti-detachment hole to limit the contact's axial movement along the housing structure.

[0021] Beneficial Effects: The extension provides a clear boundary for the axial movement of the contact along the housing structure, ensuring that the contact moves within a specific axial range. This helps to precisely control the interaction between the contact and the guide ramp, ensuring that unlocking and other operations are performed accurately according to design requirements, and preventing functional impairment due to excessive or insufficient axial displacement of the contact. Furthermore, by limiting the axial displacement of the contact, the extension reduces axial wobble and uncertainty, thereby improving the stability of the entire connection structure. In addition, when the contact and guide ramp cooperate to perform unlocking and other functions, the extension's limitation on the axial displacement of the contact makes the force transmission between the contact and the guide ramp more stable and controllable. This ensures that the contact interacts with the guide ramp in the same way during each operation, improving operational consistency and reliability, and reducing unlocking failures or operational difficulties caused by unstable axial displacement of the contact.

[0022] In one optional embodiment, the housing structure further includes: A second housing forms an installation chamber between the second housing and the first housing, and the battery compartment is located in the installation chamber.

[0023] Beneficial effects: The battery compartment is located between the second shell and the first shell to form an installation chamber. It has a simple structure, is easy to assemble, and the shell structure can effectively protect the battery inside the battery compartment.

[0024] In one alternative embodiment, the outer side of the cover is provided with a groove.

[0025] Beneficial effects: The groove on the outside of the cover allows the cover to be rotated and removed with the aid of tools during the opening process, further improving the ease of operation and making the removal of the cover more convenient and faster.

[0026] Secondly, this utility model also provides a remote control, comprising: Battery, buttons, and motherboard; The battery is disposed in the battery compartment, as described in any of the above-mentioned housing structures.

[0027] Beneficial effects: The remote control includes the housing structure of this utility model. The battery of the remote control is set in the battery compartment of the housing structure. During the unlocking process, the cover cannot be opened by hand without tools. Young children have limited cognition and do not understand the logical connection between tools and opening the housing. Therefore, children are not likely to open the cover corresponding to the battery compartment, avoiding the removal of the button battery in the battery compartment, which effectively improves safety.

[0028] Thirdly, this utility model also provides a household appliance, including the aforementioned remote control.

[0029] Beneficial effects: Since the household appliances include the remote control of this utility model, they have the same technical effects as the remote control, which will not be elaborated here. Attached Figure Description

[0036] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.

[0037] According to an embodiment of the present invention, in one aspect, a shell structure is provided, comprising: Battery compartment; The first housing 2 has a mounting hole 23 communicating with the battery compartment; the end face of the first housing 2 near the battery compartment is provided with a first connecting structure 21 and a locking part 22; The cover 1 is rotatably disposed at the mounting hole 23 to close the battery compartment; a second connecting structure 11 is provided on the end face of the cover 1 near the battery compartment; the cover 1 is provided with an anti-detachment hole 12 adapted to the locking part 22; The cover 1 has a locked state and an unlocked state; when the second connecting structure 11 is matched and connected with the first connecting structure 21, and the end of the locking part 22 is engaged in the anti-disengagement hole 12, the cover 1 is in the locked state; when a force is applied to the locking part 22 along the axial direction of the shell structure, the locking part 22 can squeeze and apply a circumferential force to the cover 1 while moving along the axial direction of the shell structure, and the cover 1 is in the unlocked state when the locking part 22 disengages from the anti-disengagement hole 12 and the second connecting structure 11 disengages from the first connecting structure 21.

[0038] During installation, rotating the cover 1 causes the second connecting structure 11 on the cover 1 to slide into the first connecting structure 21 on the first housing 2, and the locking part 22 on the first housing 2 engages in the anti-disengagement hole 12 of the cover 1. At this time, the cover 1 is in a locked state. To open it, use a tool to axially press the locking part 22 in the anti-disengagement hole 12 to disengage the locking part 22 from the anti-disengagement hole 12, and then simultaneously rotate the cover 1 circumferentially to disengage the first connecting structure 21 from the second connecting structure 11, thus unlocking the cover 1. A tool is required to open the cover 1 and remove the battery 3. Unlocking the cover 1 is impossible without a tool. Furthermore, opening the cover 1 requires two independent and simultaneous actions: pressing and rotating. Young children have limited cognitive abilities and do not understand the logical connection between the tool and opening the housing. Therefore, children may not easily open the cover 1 corresponding to the battery compartment, thus avoiding the removal of the button battery 3 inside the battery compartment and effectively improving safety.

[0039] In some embodiments, the locking portion 22 includes: The elastic arm 221 extends circumferentially along the first housing 2; Contact 222 is disposed at the end of the elastic arm 221; contact 222 is engaged in the anti-dislodgement hole 12 and contact 222 provides circumferential positioning of the cover 1.

[0040] In other embodiments, the contact 222 is engaged within the anti-detachment hole 12 to limit the cover 1 circumferentially and axially.

[0041] The elastic arm 221 is elastic, providing a certain elastic force during locking and unlocking. When the cover 1 rotates to the locked position, the elastic force of the elastic arm 221 allows the contact 222 to be more tightly engaged in the anti-disengagement hole 12, enhancing the reliability of locking. The contact 222, engaged in the anti-disengagement hole 12, provides circumferential restraint to the cover 1, ensuring locking reliability. When unlocking is required, pressing the locking part 22 in the anti-disengagement hole 12 along the axial direction of the housing structure with a tool causes the elastic arm 221 to elastically deform, allowing the contact 222 to disengage from the anti-disengagement hole 12. Simultaneously, during axial movement, the elastic arm 221 effectively transmits external force to the cover 1, compressing the cover 1 along the axial direction of the housing structure and converting the axial force into a circumferential component force applied to the cover 1, helping the cover 1 to more easily disengage from the first connecting structure 21, thus achieving unlocking. This design makes unlocking more convenient and effortless, and eliminates the need for additional complex mechanisms to achieve force conversion and transmission. The combination of the elastic arm 221 and the contact 222 has a simple and compact structure, making it easy to manufacture and assemble, while also improving the reliability and stability of the entire locking part 22. Compared to some complex locking mechanisms, this structure reduces the number of parts, lowers the probability of locking failure due to component damage, and ensures that the elastic performance of the elastic arm 221 remains relatively stable during long-term use, guaranteeing the normal operation of locking and unlocking functions. The presence of the elastic arm 221 and the contact 222 makes the locking of the cover 1 more secure, making it more difficult for children to open it by hand. The elastic force of the elastic arm 221 and the clamping force of the contact 222 require certain tools and strength to overcome. Furthermore, opening the cover 1 requires two independent and synchronized actions: pressing and rotating. This poses a significant obstacle for children with limited cognitive abilities and strength, further enhancing safety by preventing children from accidentally opening the battery compartment or accessing the button battery 3.

[0042] In some embodiments, in the locked state, the top surface of the contact 222 is lower than the top surface of the cover 1.

[0043] The top surface of contact 222 is lower than the top surface of cover 1, ensuring that contact 222 will not be accidentally touched and move axially during normal use. This prevents the locking part 22 from disengaging from the anti-disengagement hole 12, thus preventing accidental unlocking of cover 1 and maintaining the stability of the locked state. For children, since contact 222 is hidden below the top surface of cover 1, it is more difficult to unlock the cover by directly pressing or flicking contact 222. This further increases the difficulty for children to open cover 1, thus better protecting children and avoiding potential dangers from small parts such as button battery 3.

[0044] In some embodiments, the second connection structure 11 includes: At least two of the swivels are distributed circumferentially along the first housing 2.

[0045] Multiple circumferentially distributed latches provide connection force from multiple angles when the cover 1 is connected to the first housing 2, making the connection between the cover 1 and the first housing 2 more stable. Compared with a single connection structure, multiple latches can evenly distribute the force, avoiding loosening due to excessive local force, ensuring that the battery compartment will not easily open during normal use, thus improving the safety and reliability of the device. During installation, simply rotate the cover 1 to allow the latches to slide into the corresponding structure on the first housing 2 to complete the connection, making the axial limiting operation relatively simple and convenient. During disassembly, after releasing the lock of the anti-detachment hole 12 on the contact 222, continue to rotate the cover 1 in the unlocking direction, and the latches will disengage from the first housing 2 without complicated operation steps; the connection of multiple latches to the first housing 2 increases the contact area and the number of connection points between the cover 1 and the first housing 2, thereby improving the strength and rigidity of the entire housing structure and making it less prone to damage. The connection and cooperation between the latches and the first housing 2 can work better with the locking part 22 to achieve locking and unlocking functions. In the locked state, the thimble engages tightly with the first connecting structure 21 to prevent the cover 1 from continuing to rotate in the locking direction. When unlocking, the locking part 22 must be pressed, and the cover 1 must be rotated to disengage the thimble from the first connecting structure 21, thus opening the cover 1. This design makes the locking and unlocking process more reliable and smooth.

[0046] In some embodiments, the first connection structure 21 includes: The limiting buckle, at least two of which are distributed circumferentially along the cover 1; when the swivel buckle slides into the limiting buckle, the cover 1 is axially limited.

[0047] In other embodiments, the first connection structure 21 includes: At least two of the limiting buckles are distributed circumferentially along the cover 1; when the rotary buckle slides into the limiting buckle, it provides axial and circumferential limiting for the cover 1. When the swivel buckle slides into the limiting buckle, the limiting buckle axially limits the cover 1, preventing it from moving in the axial direction. This ensures a more stable connection between the cover 1 and the first housing 2, effectively preventing the battery compartment from opening due to axial movement of the cover 1 during normal use, thus avoiding battery 3 falling off or other safety issues. Multiple limiting buckles are distributed circumferentially, limiting and fixing the cover 1 from multiple angles, making the connection between the cover 1 and the first housing 2 more stable and reliable. Compared to a single limiting structure, multiple limiting buckles can evenly distribute the force, preventing loosening due to excessive local force, and improving the strength and stability of the entire housing structure. During installation, simply align the swivel buckle on the cover 1 with the limiting buckle on the first housing 2, then rotate the cover 1 to allow the swivel buckle to slide into the limiting buckle, completing the installation process. The operation is simple and convenient. During disassembly, after releasing the anti-disengagement latch 12 from the contact 222, continue rotating the cover 1 in the unlocking direction. The latch will then disengage from the limiting latch, eliminating the need for complicated procedures and facilitating maintenance operations such as battery 3 replacement. The limiting latch and locking part 22 work together effectively to achieve the locking and unlocking functions of the cover 1. In the locked state, the limiting latch axially limits the cover 1, while the locking part 22 circumferentially limits it. The two work together to firmly fix the cover 1 onto the first housing 2. During unlocking, pressing the locking part 22 disengages it from the anti-disengagement hole 12, and the latch also disengages smoothly from the limiting latch, allowing the cover 1 to open. This makes the locking and unlocking process more reliable and smooth.

[0048] In some embodiments, the second connection structure 11 includes a buckle, which is located near the anti-detachment hole 12 and has a guide slope 111.

[0049] In some other embodiments, the second connection structure 11 includes a plurality of buckles, one of which is located near the anti-detachment hole 12, and the buckle near the anti-detachment hole 12 is provided with a guide slope 111.

[0050] A guide slope 111 is provided on the thimble near the anti-disengagement buckle, so that the locking part 22 can directly apply force to the guide slope 111 when it moves away from the cover body 1. This causes the locking part 22 to disengage from the anti-disengagement hole 12 and pushes the cover body 1 to move a certain distance in a circumferential direction, thus preventing the locking part 22 from springing back and returning to the anti-disengagement hole 12.

[0051] In some embodiments, the projection of the anti-detachment hole 12 is at least partially located on the guide ramp 111 along the axial direction of the housing structure, such that the contact 222 can compress and push the guide ramp 111 as it moves away from the cover 1. Specifically, the contact 222 compresses the guide ramp 111 when it moves axially away from the cover 1.

[0052] When unlocking is required, the contact 222 moves away from the cover and presses against the guide ramp 111. Since the anti-disengagement hole 12 is at least partially projected onto the guide ramp 111, the force of the contact 222 can act more precisely on the guide ramp 111. A component force applied to the guide ramp 111 can effectively push the cover 1 circumferentially. This process reduces possible jamming or resistance during unlocking, ensuring smooth unlocking operation and facilitating the user to open the cover 1. The anti-disengagement hole 12 being at least partially projected onto the guide ramp 111 ensures that the contact 222 maintains good contact with the guide ramp 111 during its movement away from the cover 1, avoiding unlocking failure due to positional deviation between the contact 222 and the guide ramp 111. The pressure and push of the contact 222 onto the guide ramp 111 makes the circumferential movement of the cover 1 more accurate, better preventing the locking part 22 from springing back into the anti-disengagement hole 12. Because the anti-disengagement hole 12 is projected at least partially on the guide slope 111, the force of the contact 222 acting on the guide slope 111 is decomposed into an axial force along the axis of the shell structure and a circumferential force along the circumference of the cover 1. The circumferential force along the circumference of the cover 1 is more conducive to the cover 1 generating sufficient circumferential displacement, so that the locking part 22 is completely misaligned with the anti-disengagement hole 12, thereby effectively preventing the locking part 22 from springing back to reset and ensuring the stability of the unlocked state.

[0053] In some embodiments, the guide slope 111 is provided with an extension 112 on the side away from the anti-detachment hole 12 to limit the axial displacement of the contact 222.

[0054] The extension 112 provides a clear boundary limit for the axial displacement of the contact 222, ensuring that the contact 222 moves within a specific displacement range along the axial direction of the housing structure. This helps to precisely control the interaction between the contact 222 and the guide ramp 111, ensuring that unlocking and other operations can be performed accurately according to design requirements. It prevents the contact 222 from contacting the circuit board or other structures within the housing structure due to excessive axial displacement, thus avoiding damage to the circuit board or other structures. Conversely, it prevents the contact 222 from being repositioned by the anti-disengagement hole 12 due to insufficient axial displacement and small circumferential displacement of the cover 1, causing the locking part 22 to spring back. Furthermore, by limiting the axial displacement of the contact 222, the extension 112 can reduce the swaying and uncertainty of the contact 222 in the axial direction, thereby improving the stability of the entire connection structure. Furthermore, when the contact 222 engages with the guide ramp 111 to release the locking of the anti-disengagement hole 12 on the contact 222, the limitation of the axial displacement of the contact 222 by the extension 112 makes the force transmission between the contact 222 and the guide ramp 111 more stable and controllable. In this way, the contact 222 interacts with the guide ramp 111 in the same way during each operation, improving the consistency and reliability of the operation and reducing the occurrence of unlocking failures or operational difficulties due to unstable axial displacement of the contact 222.

[0055] In some embodiments, the housing structure further includes: The second housing 6 forms an installation chamber with the first housing 2, and the battery compartment is located in the installation chamber.

[0056] The battery compartment is located between the second housing 6 and the first housing 2 to form an installation chamber. It has a simple structure, is easy to assemble, and the housing structure can effectively protect the battery 3 inside the battery compartment.

[0057] In some embodiments, the outer side of the cover 1 is provided with a groove 13.

[0058] A groove 13 is provided on the outer side of the cover 1, which allows the cover 1 to be rotated and removed from the first housing 2 with the aid of a tool during the opening process, further improving the ease of operation and making the removal of the cover 1 more convenient and faster. Specifically, the groove 13 can be a cross-shaped groove.

[0059] According to an embodiment of the present invention, another aspect provides a remote control, comprising: Battery 3, button 5, and motherboard 4; The housing structure includes a battery 3 disposed within the battery compartment.

[0060] The remote control includes the housing structure of this utility model. The battery 3 of the remote control is set in the battery compartment of the housing structure. During the unlocking process, the cover 1 cannot be opened by hand without the use of tools. Young children have limited cognition and do not understand the logical connection between tools and opening the housing. Therefore, children are not likely to open the cover 1 corresponding to the battery compartment, thus avoiding the removal of the button battery 3 in the battery compartment and effectively improving safety.

[0061] In one embodiment, during assembly, the button battery 3 is first placed into the battery compartment, and then the cover 1 is screwed in along the first direction. The buckle on the cover 1 engages with the limiting buckle on the first housing 2 to prevent the cover 1 from falling off. Simultaneously, because the elastic arm 221 of the first housing 2 is an elastic structure, the contact 222 on the elastic arm is constantly pressed down by the cover 1 during rotation and is located below the cover 1. When the anti-detachment hole 12 on the cover 1 rotates to the contact 222, the elastic arm 221 automatically springs back, the contact 222 enters the anti-detachment hole 12 and automatically locks, thus preventing the cover 1 from continuing to rotate. During disassembly, a tool must first be used to press the contact 222. Through the principle of the inclined plane, the contact 222 moves axially along the housing structure. External force is transmitted through the contact 222 to the guide inclined plane 111, thereby pushing the buckle near the anti-detachment hole 12 to rotate in the second direction, causing the contact 222 to disengage from the anti-detachment hole 12, releasing the interlocking state. Then, the cover 1 can be removed by continuing to rotate in the second direction. One of the first and second directions is clockwise, and the other is counterclockwise. This structural design meets the safety standards for two independent actions and disassembly with the aid of tools, effectively preventing children from accidentally operating the device.

[0062] According to an embodiment of the present invention, in another aspect, a household appliance is also provided, including the aforementioned remote control.

[0063] Since the household appliances include the remote control of this utility model, they have the same technical effects as the remote control, which will not be described in detail here.

[0064] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
