[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] As shown in the accompanying drawings, an embodiment of the present invention provides a limiting structure 40, which has a first mating surface 41, a second mating surface 42 and an assembly guide surface 43. The first mating surface 41 and the second mating surface 42 are transitionally connected through the assembly guide surface 43, and there is an angle between the first mating surface 41 and the second mating surface 42, wherein the first mating surface 41 is used for limiting cooperation with the first component, and the second mating surface 42 is used for limiting cooperation with the second component to prevent the first component and the second component from moving relative to each other in the first direction.

[0037] By applying the technical solution of the present invention, a limiting structure 40 is provided. The limiting structure 40 has a first mating surface 41, a second mating surface 42 and an assembly guide surface 43. The first mating surface 41 and the second mating surface 42 are transitionally connected by the assembly guide surface 43. There is an angle between the first mating surface 41 and the second mating surface 42. The first mating surface 41 is used for limiting the first component, and the second mating surface 42 is used for limiting the second component to prevent the first component and the second component from moving relative to each other in the first direction. By adopting this solution, the first component and the second component can be limited by the cooperation of the limiting structure 40 with the first component and the second component, thereby preventing the first component and the second component from moving relative to each other. This solution can also be understood as inserting the limiting structure 40 into the gap between the first component and the second component to play a limiting and protective role. The limiting structure 40 can be easily placed between the first component and the second component through the assembly guide surface 43.

[0038] In this embodiment, the limiting structure 40 includes a main body 50 and a protective strip 60 disposed on the main body 50. The first mating surface 41, the second mating surface 42 and the assembly guide surface 43 are all located on the main body 50. The protective strip 60 has a third mating surface 44. There is an angle between the first mating surface 41 and the third mating surface 44. The first mating surface 41 and the third mating surface 44 are respectively used for limiting mating with different surfaces of the first component. The third mating surface 44, the first mating surface 41 and the second mating surface 42 are arranged in an S shape. Through this arrangement, the first mating surface 41 and the third mating surface 44 can be limitedly matched with different surfaces of the first component. Since there is an angle between the first mating surface 41 and the third mating surface 44, the limiting structure 40 and the first component are less likely to move relative to each other, so that the first component and the second component are also less likely to move relative to each other, thereby improving the limiting effect of the limiting structure 40.

[0039] In this embodiment, the main body 50 further has a fourth mating surface 45, and there is an angle between the fourth mating surface 45 and the second mating surface 42, and the second mating surface 42 and the fourth mating surface 45 are respectively used for position-limiting cooperation with different surfaces of the second component. In this way, the second mating surface 42 and the fourth mating surface 45 can be position-limited cooperation with different surfaces of the second component. Since there is an angle between the fourth mating surface 45 and the second mating surface 42, the limiting structure 40 and the second component are less likely to move relative to each other, so that the first component and the second component are also less likely to move relative to each other, and the limiting effect of the limiting structure 40 is further improved.

[0040] Furthermore, the second mating surface 42 is located at the lower side of the main body 50, and the second mating surface 42 is used to abut against the second component. The fourth mating surface 45 has a card slot 51, and the card slot 51 is used to engage with the second component. In this way, the connection between the limiting structure 40 and the second component can be achieved by abutting the end faces and engaging the card slot 51, thereby improving the connection reliability between the limiting structure 40 and the second component, avoiding or reducing the shaking of the second component during transportation, and improving the limiting effect.

[0041] In this embodiment, the main body 50 includes at least one first protection segment 52 and at least two second protection segments 53. Two adjacent second protection segments 53 are connected by the first protection segment 52. Each second protection segment 53 is provided with a slot 51. The at least two second protection segments 53 are used to match with at least two second components in a one-to-one correspondence. Through the above arrangement, a limiting structure 40 can limit and protect at least two second components, so that when multiple components need to be limited, the number of parts can be reduced and the assembly efficiency can be improved.

[0042] Furthermore, the limiting structure 40 has a limiting end 54, which is located in the length direction of the limiting structure 40. The limiting end 54 is used to abut against the second component to prevent the first component and the second component from relative movement in the second direction, and there is an angle between the second direction and the first direction. Through this arrangement, the first component and the second component can be limited in different directions, thereby improving the limiting effect and preventing the two from relative movement or even collision. The first direction can be the up-down direction, and the second direction can be the horizontal direction.

[0043] In this embodiment, the limiting structure 40 is made of an elastic material. In this way, the limiting structure 40 has a certain elasticity, which can provide a buffering and vibration reduction effect on the first component and the second component. In addition, the limiting structure 40 is easy to elastically deform, which is convenient for assembly and disassembly. Specifically, the limiting structure 40 can be made of rubber or silicone.

[0044] Another embodiment of the present invention provides an air conditioner, the air conditioner comprises a first component, a second component and a limiting structure 40, the limiting structure 40 is the above-mentioned limiting structure 40, and the limiting structure 40 is detachably arranged between the first component and the second component. With this solution, before transporting the air conditioner, the limiting structure can be assembled between the second component and the first component, and since both the second component and the first component are limited by the limiting structure, the second component can be limited in position, the second component is prevented from moving during transportation, and the first component and the second component are prevented from colliding.

[0045] Specifically, the air conditioner further comprises a housing, the housing has an air outlet, the first component is a top cover 20, the top cover 20 is arranged at the upper end of the housing, and the second component is a door panel 30, the door panel 30 is arranged on the housing, and the door panel 30 is movably arranged along a preset path to open and close the air outlet. In this way, the door panel 30 and the top cover 20 can be protected during transportation. When the transportation is completed, the limiting structure 40 can be removed.

[0046] In this embodiment, the outer periphery of the top cover 20 is an annular structure, and the door panel 30 is an arc-shaped panel; the limiting structure 40 is an arc-shaped structure to match the area between the top cover 20 and the door panel 30. Through the above arrangement, the limiting structure 40 can match the shapes of the top cover 20 and the door panel 30, thereby improving the limiting and protection effects.

[0047] In this embodiment, the surface of the top cover 20 facing the door panel 30 is an arc-shaped surface, the shape of the first matching surface 41 of the limiting structure 40 matches the arc-shaped surface, the second matching surface 42 is located at the lower side of the limiting structure 40, and the second matching surface 42 of the limiting structure 40 abuts against the door panel 30. Such a configuration can increase the contact area between the limiting structure 40 and the top cover 20, thereby improving the effect of limiting and buffering vibration reduction. Through the abutment of the second matching surface 42 with the door panel 30, the door panel 30 can be limited and protected.

[0048] In this embodiment, the limiting structure 40 includes a main body 50 and a protective strip 60 disposed on the main body 50, the main body 50 has a first mating surface 41, the protective strip 60 has a third mating surface 44, a groove for accommodating a partial structure of the top cover 20 is provided between the first mating surface 41 and the third mating surface 44, the first mating surface 41 wraps at least a portion of the side surface of the top cover 20, the third mating surface 44 wraps at least a portion of the top surface of the top cover 20, and the door panel 30 is matched with the main body 50. Through the above arrangement, the limiting structure 40 can protect different positions of the top cover 20 to prevent friction damage during transportation, and can improve the connection strength between the limiting structure 40 and the top cover 20 and the protective effect on the door panel 30.

[0049] Optionally, the top cover 20 includes a decorative plate 21 and a decorative strip 22 disposed above the decorative plate 21, and the decorative plate 21 is connected to the housing. The first mating surface 41 is mated with the surface of the decorative plate 21, and the third mating surface 44 is mated with the surface of the decorative strip 22, thereby protecting the decorative plate 21 and the decorative strip 22.

[0050] In this embodiment, the limiting structure 40 includes a main body 50, and the main body 50 has a first matching surface 41 and a fourth matching surface 45, wherein the first matching surface 41 abuts against the side surface of the top cover 20, and the fourth matching surface 45 has a card slot 51, and the card slot 51 is card-engaged with the door panel 30. In this way, the main body 50 and the door panel 30 can be reliably connected by card connection, so that the door panel 30 can be reliably limited.

[0051] Furthermore, the lower side of the main body 50 has a second mating surface 42, and the door panel 30 includes a panel 31 and a first protrusion 32 and a second protrusion 33 spaced apart on the panel 31, wherein the first protrusion 32 is located above the second protrusion 33, wherein the first protrusion 32 is engaged with the card slot 51, and the second mating surface 42 is in contact with the upper surface of the second protrusion 33. In this way, the reliable connection between the limiting structure 40 and the door panel 30 can be achieved through the engagement of the first protrusion 32 with the card slot 51 and the engagement of the second mating surface 42 with the second protrusion 33.

[0052] In this embodiment, the air conditioner includes at least two door panels 30 arranged at intervals, the main body 50 includes at least one first protection segment 52 and at least two second protection segments 53, the two ends of the first protection segment 52 are respectively connected to the two second protection segments 53, each second protection segment 53 is provided with a slot 51, and at least the second protection segment 53 is matched with at least two door panels 30 in a one-to-one correspondence. In this way, the at least two door panels 30 can be limited by different parts of the limiting structure 40, without the need to respectively provide limiting structures for the at least two door panels 30, which is convenient for assembly and has low production costs.

[0053] Furthermore, the air conditioner further comprises: a display screen 70, which is arranged on the housing, and the display screen 70 is located between the two door panels 30, and the bottom surface of the first protective section 52 abuts against the top surface of the display screen 70. The above arrangement can improve the fixing effect of the limiting structure 40, thereby improving the limiting and protective effect of the door panels 30 and other structures.

[0054] In this embodiment, the limiting structure 40 includes a main body 50, and the main body 50 has a first mating surface 41, a fourth mating surface 45 and a limiting end 54, wherein the first mating surface 41 abuts against the side of the top cover 20, the fourth mating surface 45 matches with the door panel 30, and the limiting end 54 abuts against the door panel 30 to prevent the door panel 30 from moving along the preset path. In this way, the limiting end 54 of the limiting structure 40 abuts against the door panel 30, so that the door panel 30 can be prevented from moving along the preset path, thereby preventing the door panel 30 from opening during transportation, thereby improving safety.

[0055] Specifically, the door panel 30 includes a panel 31 and a rib 34 vertically arranged on the panel 31, the main body 50 includes a first protective segment 52 and a second protective segment 53 connected to each other, the fourth matching surface 45 is located on the second protective segment 53, and the fourth matching surface 45 matches the panel 31; in the height direction, the bottom surface of the second protective segment 53 is lower than the bottom surface of the first protective segment 52, the limiting end 54 is located at the end of the second protective segment 53, and the limiting end 54 abuts against the rib 34. In this way, the door panel 30 can be reliably limited by the abutment between the limiting end 54 and the rib 34.

[0056] Optionally, the second protection segment 53 further has a transition slope, and the fourth matching surface 45, the transition slope and the end surface of the limiting end 54 are connected in sequence, which facilitates structural transition and matching of different components.

[0057] By applying the technical solution of the present invention, an air conditioner is provided, which includes an outer shell, a top cover 20, a door panel 30 and a limiting structure 40, wherein the outer shell has an air outlet; the top cover 20 is arranged at the upper end of the outer shell; the door panel 30 is arranged on the outer shell, and the door panel 30 is movably arranged along a preset path to open and close the air outlet; the limiting structure 40 is detachably arranged between the top cover 20 and the door panel 30, and both the door panel 30 and the top cover 20 are limited by the limiting structure 40, and the limiting structure 40 is made of elastic material. By adopting this solution, before transporting the air conditioner, the limiting structure 40 can be assembled between the door panel 30 and the top cover 20. Since the door panel 30 and the top cover 20 are both limited by the limiting structure 40, the door panel 30 can be limited to prevent the door panel 30 from moving during transportation. Moreover, the limiting structure 40 is made of elastic material, which can play a role in buffering and vibration reduction while limiting the position, thereby better protecting the door panel 30 and other structures.

[0058] The structure of the limiting structure 40 of this solution limits the upward and downward movement of the door panel during transportation. The elasticity and matching structure of the limiting structure 40 of this solution buffer the influence of thermal expansion and contraction on the structure during transportation of the machine. The left and right front and back limiting functions of the limiting structure 40 are used to limit the shaking during transportation, ensuring that the part will not rub against other parts during transportation, resulting in scratches. The left and right limiting structures of the limiting structure 40 of this solution, i.e., the limiting ends 54, limit the opening and closing of the door panel, protecting the motor and other parts that match the door panel.

[0059] In this solution, a guide and buckle structure are provided on the limit structure 40, so that the assembly is simple and convenient. With an arc-shaped structure, the structure can be directly stuck in place, not easy to fall off, and no screws are required, which is convenient for installation. The upper side structure of the limit structure 40 of this solution protects the electroplated decorative strip from being easily scratched.

[0060] This solution can use a rubber block with a hardness of about 60, and use the elasticity of the rubber block to cushion its vibration during transportation, so that it can withstand a certain impact and better protect the parts.

[0061] This solution can not only meet the requirements of door panels and corresponding moving parts, but also ensure a better appearance under the same conditions. The structural characteristics of the rubber block are used to match the door panels, top covers, decorative panels, decorative strips, display panels and other parts, which are easy to disassemble and assemble with high efficiency. The structural characteristics of the rubber block are used to ensure that the door panel will not open during transportation, or move to affect other parts, thereby ensuring that other parts are not rubbed and the appearance effect is guaranteed. The elastic characteristics of the limiting structure 40 can ensure that the door panels, decorative strips and other parts are evenly stressed during transportation, buffer vibrations, and better protect moving parts.

[0062] The limiting structure 40 used in this solution is only used in the packaging stage. After unpacking, the limiting structure 40 needs to be removed before the air conditioner can be used. The limiting structure 40 adopts an arc-shaped structure, which can be directly stuck in the gap between the door panel and the top cover, and will not fall off. There is no need to screw, etc., and the disassembly and assembly are simple. Just flip the decorative pad up and pull the lower side to take out the limiting structure 40. This solution pads the door panels on both sides and forms a limit with the surrounding side structure to limit the movement of parts such as door panels during transportation, protect parts such as decorative panels, and avoid affecting other parts. Through the elasticity and friction with the contact surface, a buffer structure is formed. With one part, multiple surrounding parts are well protected during transportation.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
