[0041] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A, or B, or, A and B.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0043] Combination Figure 1-7 As shown, an embodiment of the present disclosure provides a housing assembly of an air conditioner indoor unit, including a panel 10 , an air inlet grille 20 and a self-locking device 30 .

[0044] The panel 10 is provided with a mounting hole 11; the air inlet grille 20 is provided at the mounting hole 11 and can be in a closed position (the closed position is as shown in FIG. 1 ) relative to the panel 10 in the closed mounting hole 11. Figure 1 The air inlet grille 20 includes a grille body 21 and a locking portion 22 provided on the grille body 21; the self-locking device 30 includes a locking portion 31, which is provided on the panel 10 and can be relative to the panel 10 in a locking position (locking position as shown in FIG. Figure 3 wherein, in the locked position, the force applied by the locking portion 31 to the locking mating portion 22 has at least a component force from the open position toward the closed position.

[0045] The air inlet grille 20 can move relative to the panel 10 between a closed position closing the mounting hole 11 and an open position opening the mounting hole 11, and can be stably locked by the self-locking device 30. In the locked position, the force applied by the locking portion 31 to the locking mating portion 22 has at least a component from the open position toward the closed position, so that the self-locking device 30 can apply a force to the air inlet grille 20 from the open position toward the closed position, and bear the gravity of the air inlet grille 20.

[0046] Among them, in the locked position, the force applied by the locking portion 31 to the locking matching portion 22 may have a component force from the open position toward the closed position, or the force applied by the entire locking portion 31 to the locking matching portion 22 may be applied from the open position toward the closed position. When the force applied by the entire locking portion 31 to the locking matching portion 22 is applied from the open position toward the closed position, the lifting motor can be in a state of being completely free of force, which can more effectively enhance the reliability of the self-locking device 30 and protect the lifting motor.

[0047] Compared with the related art that locks the panel 10 through the self-locking function of the lifting transmission matched with the lifting motor, the self-locking device 30 separately provided in the embodiment of the present disclosure can transfer the gravity of the air inlet grille 20 to the self-locking device 30, thereby reducing the continuous load on the lifting motor and protecting the lifting motor by transferring the gravity load. At the same time, the housing assembly realizes the locking and unlocking of the air inlet grille 20 through the self-locking device 30, which can avoid the problem of damage to the lifting motor caused by long-term locking work when the lifting motor is self-locked. Therefore, the embodiment of the present disclosure can enhance the protection of the lifting motor and enhance the reliability of the self-locking function of the air inlet grille 20 on the basis of achieving the locking of the air inlet grille 20.

[0048] Therefore, by using the housing assembly of the indoor unit of the air conditioner provided by the embodiment of the present disclosure, by separately providing the self-locking device 30, when the air inlet grille 20 is in the closed position, the locking portion 31 of the self-locking device 30 cooperates and locks with the locking matching portion 22 of the air inlet grille 20, so that the air inlet grille 20 can be stably maintained in the closed position. At the same time, in the locked position, the force applied by the locking portion 31 to the locking matching portion 22 has at least a component force from the open position toward the closed position, so that the self-locking device 30 can bear the gravity of the air inlet grille 20, thereby enhancing the reliability of the self-locking function of the air inlet grille 20.

[0049] Optionally, combined Figure 3 As shown, in the locking position, the locking matching portion 22 abuts against the locking portion 31 and along the direction from the closed position to the open position, the locking matching portion 22 and the locking portion 31 are arranged in sequence.

[0050] The direction from the closed position to the open position is as follows Figure 7 shown.

[0051] In the locked position, the locking part 22 and the locking part 31 are arranged in sequence along the direction from the closed position to the open position, and in the closed position, the air inlet grille 20 closes the mounting hole 11, that is, the locking part 31 is located on the side of the locking part 22 away from the mounting hole 11. At the same time, the locking part 22 abuts against the locking part 31, so that the locking part 22 can more effectively apply the force of the locking part 31 to achieve a tight fit between the air inlet grille 20 and the panel 10. In this way, the locking part 31 can apply the force of the locking part 22 from the open position to the closed position, so that the gravity of the air inlet grille 20 can be more effectively carried, and the stability of the air inlet grille 20 in the locked position is enhanced.

[0052] Optionally, combined Figure 3 As shown, a first guide bevel 221 is provided on the surface of the locking mating portion 22 facing the locking portion 31, and a second guide bevel 311 is provided on the surface of the locking portion 31 facing the locking mating portion 22. Along the direction in which the locking portion 31 moves from the unlocked position to the locked position, the second guide bevel 311 is inclined in a direction away from the locking mating portion 22, and the first guide bevel 221 is adapted to the second guide bevel 311.

[0053] The direction of movement from the unlocked position to the locked position is as follows: Figure 3 shown.

[0054] Along the direction in which the locking portion 31 moves from the unlocked position to the locked position, the second guide bevel 311 is inclined toward a direction away from the locking mating portion 22, and the first guide bevel 221 is adapted to the second guide bevel 311, and along the direction in which the locking portion 31 moves from the unlocked position to the locked position, the first guide bevel 221 is inclined toward a direction close to the locking portion 31.

[0055] The first guide slope 221 and the second guide slope 311 are adapted and inclined, and can guide the locking part 31 to move toward the locking position, so that the locking part 31 can be more accurately positioned at the locking position. At the same time, the first guide slope 221 and the second guide slope 311 both provide an inclined path, so that the locking part 31 can smoothly and steadily move from the unlocking position to the locking position to cooperate with the locking matching part 22, avoiding interference between the locking part and the locking matching part during the movement, and reducing wear during the movement.

[0056] Optionally, in the unlocked position, the orthographic projections of the locking fitting portion 22 and the locking portion 31 on a preset plane do not overlap, wherein the preset plane is perpendicular to a line connecting the closed position and the open position.

[0057] The preset plane is perpendicular to the line connecting the closed position and the open position. In the unlocked position, the orthographic projections of the locking mating portion 22 and the locking portion 31 on the preset plane do not overlap, so that in the unlocked position, the locking mating portion 22 and the locking portion 31 are prevented from interfering with each other, thereby ensuring that the air inlet grille 20 can move freely and smoothly between the closed position and the open position.

[0058] Optionally, combined Figure 3 As shown, the self-locking device 30 further includes a driving member 32, which is drivingly connected to the locking portion 31 and is used to drive the locking portion 31 to move between a locking position and an unlocking position.

[0059] By driving the locking portion 31 to move between the locking position and the unlocking position through the driving member 32 , the operating accuracy and response speed of the self-locking device 30 can be improved, and the reliability of the self-locking device 30 can be improved.

[0060] Optionally, the driving member 32 includes a stepping motor.

[0061] By using a stepper motor to drive the locking part 31 to move between the locked position and the unlocked position, a fixed number of steps can be preset to accurately control the moving position of the locking part 31. By driving the locking part 31 to move between the locked position and the unlocked position by a stepper motor, an accurate driving force can be provided to the locking part 31, thereby improving the stability of locking and unlocking.

[0062] Optionally, the driving member 32 further includes a transmission component, which is disposed on the panel 10 , is drive-connected to the stepping motor, and is drive-connected to the locking portion 31 .

[0063] The provision of the transmission component can enhance the power transmission from the stepper motor to the locking portion 31 , and improve the stability and reliability of the locking and unlocking effects.

[0064] Optionally, combined Figure 3 and Figure 6 As shown, the transmission component includes a gear 321 and a rack 322, the gear 321 is connected to the stepper motor drive, the rack 322 is connected to the locking part 31, and the gear 321 and the rack 322 cooperate to enable the locking part 31 to move between a locked position and an unlocked position relative to the panel 10.

[0065] It can be understood that the rack 322 and the locking part 31 can also be connected in one piece. The self-locking device 30 includes a card 33, and the locking part 31 and the rack 322 are arranged on opposite sides of the card 33. The locking part 31 is arranged on the side of the card 33 facing the locking matching part 22, and the rack 322 is arranged on the side of the card 33 away from the locking matching part 22. In this way, the structure can be simplified, making the self-locking device 30 more compact. The gear 321 drives the rack 322 to move through transmission to achieve transmission of the locking part 31. A stepper motor is used to drive the gear 321 to rotate, and the gear 321 cooperates with the rack 322. The card 33 is driven to move through the rack 322 transmission, so that the locking part 31 cooperates with the locking matching part 22.

[0066] Optionally, the shell assembly of the air conditioner indoor unit also includes a detection element and a controller, the detection element is arranged on the air inlet grille 20 and / or the panel 10, and is used to detect the position of the air inlet grille 20 relative to the panel 10; the controller is connected to the detection element and the driving member 32, and is used to control the driving member 32 to drive the locking part 31 to move toward the locking position when the detection element detects that the air inlet grille 20 is in the closed position.

[0067] The detection element may be a position sensor such as a micro switch. The position of the air inlet grille 20 is detected by the detection element, and the detection information is transmitted to the controller. The controller controls the driving member 32 to drive the locking portion 31 to move according to the position information of the air inlet grille 20. When it is detected that the air inlet grille 20 is in the closed position, the controller controls the driving member 32 to drive the locking portion 31 to move toward the locking position, locking the air inlet grille 20 and the panel 10. Through the cooperation of the detection element and the controller, the real-time monitoring and control of the position of the air inlet grille 20 is realized, the intelligence level of the self-locking device 30 is improved, and the safety of operation is ensured.

[0068] Optionally, combined Figure 3 and Figure 6 As shown, the housing assembly of the air conditioner indoor unit further includes a limiting portion 12, which is disposed on the panel 10 and cooperates with the locking portion 31 to limit the locking portion 31 to move between a locking position and an unlocking position.

[0069] The limiting portion 12 can limit the movement range of the locking portion 31 in the panel 10 to prevent the locking portion 31 from being damaged due to excessive movement, thereby improving the durability of the self-locking device 30 .

[0070] Since the locking portion 31 is in transmission connection with the driving member 32, the driving member 32 and the limiting portion 12 can jointly limit the locking portion 31. The locking portion 31 is pressed between the limiting portion 12 and the driving member 32. Figure 3 As shown, the limiting portion 12, the locking portion 31 and the driving member 32 are arranged in sequence from top to bottom, so that the limiting can be achieved more effectively while driving the locking portion 31 to move.

[0071] Optionally, combined Figure 3 and Figure 6 As shown, the limiting portion 12 includes a limiting plate 121 extending from the unlocking position to the locking position. The lower surface of the limiting plate 121 can effectively limit the locking portion 31, limiting the locking portion 31 from moving in a bottom-up direction relative to the panel 10.

[0072] Optionally, combined Figure 3 and Figure 6 As shown, the limiting part 12 also includes a slot 122, which extends in the horizontal direction, and the extending direction of the slot 122 is perpendicular to the direction of movement from the unlocking position to the locking position, and the limiting plate 121 is located on the upper side of the slot 122; the locking part 31 is provided on a card 33, and the card 33 is inserted into the slot 122 to limit the movement of the locking part 31 between the locking position and the unlocking position. Through the limiting mode of the combination of the slot 122 and the limiting plate 121, the locking part 31 can be limited to move in the direction perpendicular to the movement from the unlocking position to the locking position, thereby enhancing the limiting effect.

[0073] Optionally, combined Figure 1 , Figure 4 and Figure 7 As shown, the shell assembly of the air conditioner indoor unit also includes a lifting device 40, which is driven and connected to the air inlet grille 20, and is used to drive the air inlet grille 20 to move between an open position and a closed position; wherein, there are multiple lifting devices 40, and the number of self-locking devices 30 is equal to the number of lifting devices 40 and corresponds one to one.

[0074] The lifting device 40 is drivingly connected to the air inlet grille 20 to drive the air inlet grille 20 to move between the open and closed positions. The number of the lifting devices 40 is equal to and corresponds to the number of the self-locking devices 30, and can promote the synchronous movement of the air inlet grille 20.

[0075] Optionally, the number of lifting devices 40, self-locking devices 30 and detection elements are equal and correspond one to one, and each lifting device 40, self-locking device 30 and detection element form a group of independent control systems. Each group of independent control systems does not interfere with each other, and the position of the air inlet grille 20 corresponding to each group of independent control systems can be controlled separately.

[0076] The present application takes the number of lifting devices 40 as four as an example. The four lifting devices 40 are connected to the air inlet grille 20 by driving, and are evenly arranged on the air inlet grille 20, for lifting and lowering the air inlet grille 20. A micro switch is provided on each lifting device 40 for detecting the position of the air inlet grille 20 relative to the panel 10, and the micro switch is connected to the controller by driving. When the micro switch detects that the air inlet grille 20 is in the closed position, the detection signal is transmitted to the controller, and the controller controls the driving member 32 to drive the locking portion 31 to move toward the locking position, and the locking portion 31 cooperates with the locking matching portion 22 to lock the air inlet grille 20.

[0077] Optionally, the lifting device 40 includes a drive assembly.

[0078] The driving component includes a lifting motor, which can be a stepping motor, a DC motor, a servo motor or other motor equipment.

[0079] Optionally, the drive assembly is connected to the controller for driving. The controller controls the drive assembly to work.

[0080] The first guiding inclined surface 221 of the locking matching portion 22 is matched with the second guiding inclined surface 311 of the locking portion 31 , and can guide the locking portion 31 to move to a state where the lifting motor is completely free of force.

[0081] Take the embedded air conditioner as an example. When the air inlet grille 20 is started to open, the driving member 32 of the self-locking device 30 drives the locking part 31 to move toward the unlocking position, so that the air inlet grille 20 is unlocked. At this time, the timing starts, and the lifting device 40 is delayed to start, providing enough movement time for the locking part 31. After the lifting device 40 is started, the air inlet grille 20 is driven down to the open position. When the air inlet grille 20 is started to close, the lifting device 40 drives the air inlet grille 20 to rise to the closed position, the micro switch is closed, and the controller controls the lifting device 40 corresponding to the micro switch to stop running. The controller controls the driving member 32 of the self-locking device 30 to operate, driving the locking part 31 to move toward the locking position, and locking the air inlet grille 20.
