[0002] In the indoor wall-mounted unit of the air conditioner, the air conditioner panel is installed on the middle frame. When the air conditioner needs to be repaired and cleaned, the panel needs to be opened so that the maintenance personnel or cleaning personnel can repair the internal circuits of the air conditioner or clean the filter.

[0003] However, the panel and the middle frame in the existing air conditioner are generally connected by screws. This installation method is relatively cumbersome and inconvenient for the staff to disassemble and assemble the panel. Utility Model Content

[0004] The problem solved by the utility model is that the existing central panel of the air conditioner is inconvenient to install.

[0005] In order to solve the above problems, the utility model provides a panel and middle frame installation structure, including:

[0006] A panel, one side of which is provided with a snap-fastener and a limiting protrusion;

[0007] A middle frame, one side of which is provided with a matching hole;

[0008] Among them, when the spring fastener and the limiting protrusion are matched with the matching hole at the same time, the limiting protrusion limits the spring fastener in the matching hole, so that the spring fastener is matched with the matching hole to connect the panel and the middle frame.

[0009] The present application realizes the connection between the panel and the middle frame by setting a spring fastener and a limiting protrusion on one side of the panel and a matching hole on one side of the middle frame. The limiting protrusion and the spring fastener are matched with the matching hole at the same time, so that the limiting protrusion can limit the spring fastener in the matching hole, so that the spring fastener can be quickly positioned in the matching hole, thereby realizing precise matching between the spring fastener and the matching hole. This can not only ensure the fast and accurate installation of the panel and the middle frame, but also facilitate the disassembly and assembly operations of the staff.

[0010] Optionally, a step is provided at one end of the spring fastener away from the panel, and the step includes a first guide surface, and the first guide surface is used to guide the spring fastener to cooperate with the matching hole in a first direction.

[0012] Optionally, a fixing buckle is provided in the matching hole, and the fixing buckle includes a second guide surface, and the second guide surface is used to cooperate with the first guide surface to guide the spring fastener to cooperate with the fixing buckle.

[0013] By providing a second guide surface on the fixing buckle and directly cooperating with the first guide surface through the second guide surface, the relative sliding between the spring fastener and the fixing buckle is smoother, thereby enabling the panel and the middle frame to be installed more quickly.

[0014] Optionally, the step platform further includes a third guide surface, and the third guide surface is arranged on a side of the first guide surface close to the panel;

[0015] The fixing buckle further includes a fourth guide surface, and the fourth guide surface is arranged opposite to the second guide surface;

[0016] Wherein, after the first guide surface cooperates with the second guide surface, the third guide surface cooperates with the fourth guide surface to guide the spring fastener to cooperate with the fixed buckle.

[0017] By providing the third guide surface and the fourth guide surface, the cooperation between the spring fastener and the fixed buckle can be further guided, so that the connection between the panel and the middle frame can be completed more quickly. In addition, the abutment between the third guide surface and the fourth guide surface after the cooperation is completed can limit the spring fastener, thereby improving the stability of the connection between the panel and the middle frame.

[0018] Optionally, the angle between the first guide surface and the vertical surface is a first angle, the angle between the second guide surface and the vertical surface is a second angle, the angle between the third guide surface and the vertical surface is a third angle, and the angle between the fourth guide surface and the vertical surface is a fourth angle;

[0019] Among them, the angle of the first angle is smaller than the angle of the second angle, and the angle of the third angle is larger than the angle of the fourth angle.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below.

[0044] See also Figures 1 to 7 The embodiment of the present application provides a panel and middle frame installation structure 100, including a panel 10 and a middle frame 20, a spring fastener 30 and a limiting protrusion 40 are provided on one side of the panel 10, and a matching hole 50 is provided on one side of the middle frame 20; wherein, when the spring fastener 30 and the limiting protrusion 40 are matched with the matching hole 50 at the same time, the limiting protrusion 40 limits the spring fastener 30 in the matching hole 50, so that the spring fastener 30 is matched with the matching hole 50 so that the panel 10 is connected to the middle frame 20. The present application sets a spring fastener 30 and a limiting protrusion 40 on one side of the panel 10, and sets a matching hole 50 on one side of the middle frame 20 to achieve the connection between the panel 10 and the middle frame 20, wherein, by simultaneously matching the limiting protrusion 40 and the spring fastener 30 with the matching hole 50, the limiting protrusion 40 can limit the spring fastener 30 in the matching hole 50, so that the spring fastener 30 can be quickly positioned in the matching hole 50, thereby achieving precise matching between the spring fastener 30 and the matching hole 50, which can not only ensure the rapid and accurate installation of the panel 10 and the middle frame 20, but also facilitate the disassembly and assembly operations of the staff.

[0045] In addition, in the related art, there is an example of using the buckle on the middle frame 20 to match the U-shaped groove on the panel 10 to achieve the connection between the panel 10 and the middle frame 20, but this assembly method will have a series of problems, for example, when the buckle gap is large, it will enter the wrong assembly position, and when the buckle gap is small, it will increase the difficulty of mold manufacturing. Relatively speaking, the present application limits the spring fastener 30 by the limiting protrusion 40, which can prevent the spring fastener 30 from entering the wrong assembly position, thereby causing the spring fastener 30 to break, thereby improving the accuracy of assembly and the assembly efficiency.

[0046] The end of the spring catch 30 away from the panel 10 is provided with a step 60, and the step 60 includes a first guide surface 610, and the first guide surface 610 is used to guide the spring catch 30 to cooperate with the matching hole 50 in a first direction. In some embodiments, the first guide surface 610 is provided at the outermost end of the step 60, that is, in the process of matching the panel 10 and the middle frame 20, the first guide surface 610 on the spring catch 30 is matched with the middle frame 20 first relative to other surfaces of the step 60.

[0047] In some embodiments, a fixing buckle 70 is disposed in the mating hole 50, the fixing buckle 70 is connected to the side wall of the mating hole 50, and the fixing buckle 70 includes a second guide surface 710, and the second guide surface 710 is used to cooperate with the first guide surface 610 to guide the spring catch 30 to cooperate with the fixing buckle 70. Among them, the second guide surface 710 is disposed at the outermost end of the fixing buckle 70, that is, in the mating process of the panel 10 and the middle frame 20, the second guide surface 710 on the fixing buckle 70 is first matched with the first guide surface 610 relative to other surfaces of the fixing buckle 70.

[0048] In some embodiments, the step 60 also includes a third guide surface 620, which is arranged on the side of the first guide surface 610 close to the panel 10; the fixing buckle 70 also includes a fourth guide surface 720, which is arranged opposite to the second guide surface 710; wherein, after the first guide surface 610 cooperates with the second guide surface 710, the third guide surface 620 cooperates with the fourth guide surface 720 to guide the spring fastener 30 to cooperate with the fixing buckle 70. The present application guides the step 60 and the fixed buckle 70 to slide relative to each other through the cooperation between the first guide surface 610 and the second guide surface 710 so that part of the spring fastener 30 is inserted into the matching hole 50, and then guides the step 60 and the fixed buckle 70 to slide further relative to each other through the cooperation between the third guide surface 620 and the fourth guide surface 720, and finally the spring fastener 30 is completely inserted into the matching hole 50. After the cooperation, the fourth guide surface 720 of the fixed buckle 70 can abut against the third guide surface 620 of the spring fastener 30, so as to limit the spring fastener 30 to prevent the spring fastener 30 from moving in the assembly direction.

[0049] Furthermore, the fixing buckle 70 also includes an abutment surface 740, which is connected to the fourth guide surface 720. When the spring fastener 30 is mated with the mating hole 50, the side surface of the spring fastener 30 provided on the panel 10 contacts the abutment surface 740 on the fixing buckle 70 to further limit the spring fastener 30 in the assembly direction, thereby ensuring the stability of the installation of the panel 10 and the middle frame 20.

[0050] The angle between the first guide surface 610 and the vertical surface is a first angle α, the angle between the second guide surface 710 and the vertical surface is a second angle β, the angle between the third guide surface 620 and the vertical surface is a third angle δ, and the angle between the fourth guide surface 720 and the vertical surface is a fourth angle γ.

[0051] Exemplarily, the ladder platform 60 also includes a first connecting surface 630 connecting the first guide surface 610 and the third guide surface 620, and the fixing buckle 70 also includes a second connecting surface 730 connecting the second guide surface 710 and the fourth guide surface 720, and the first connecting surface 630 and the second connecting surface 730 are arranged in parallel; there is a first angle α between the first guide surface 610 and the first connecting surface 630, a second angle β between the second guide surface 710 and the second connecting surface 730, a third angle δ between the third guide surface 620 and the first connecting surface 630, and a fourth angle γ between the fourth guide surface 720 and the second connecting surface 730.

[0052] Among them, considering that the friction force of line contact is smaller than that of surface contact, the force required for engagement and disengagement is smaller, therefore, the angle of the first angle α is smaller than the angle of the second angle β, and the angle of the third angle δ is larger than the angle of the fourth angle γ.

[0053] In order to prevent stress concentration and breakage of the spring fastener 30, in some embodiments, a reinforcing rib 80 is provided on the side of the spring fastener 30 away from the step 60. The reinforcing rib 80 is provided at one end of the spring fastener 30 close to the panel 10 and connects the spring fastener 30 and the panel 10. By providing the reinforcing rib 80, the root of the spring fastener 30 is strengthened to prevent stress concentration.

[0054] In order to further prevent stress concentration and the snap member 30 from breaking, in some embodiments, a large chamfer is designed on the snap member 30, so as to prevent stress concentration and enhance elasticity. Exemplarily, the side of the snap member 30 away from the step 60 includes a first side wall 310 and a second side wall 320, one end of the first side wall 310 is connected to the panel 10, the other end of the first side wall 310 is connected to the second side wall 320, and the second side wall 320 is bent relative to the first side wall 310. The first side wall 310 includes a first sub-side wall and a second sub-side wall that are arranged opposite to each other, and the second side wall 320 includes a third sub-side wall and a fourth sub-side wall that are arranged opposite to each other, the first sub-side wall is connected to the third sub-side wall, and the second sub-side wall is connected to the fourth sub-side wall.

[0055] The limiting protrusion 40 includes a fifth guide surface 410, which is disposed at the free end of the limiting protrusion 40, and is used to guide the limiting protrusion 40 to cooperate with the matching hole 50 in the second direction, wherein the second direction is different from the first direction. By guiding the limiting protrusion 40 to cooperate with the matching hole 50 in the second direction, the limiting protrusion 40 can be limited in the left and right directions to prevent the limiting protrusion 40 from being assembled in the wrong position, thereby increasing assembly efficiency.

[0056] The limiting protrusion 40 further includes a third connecting surface 420, one end of which is connected to the panel 10, and the other end of which is connected to the fifth guide surface 410, and the third connecting surface 420 and the fifth guide surface 410 are bent relative to each other; when the limiting protrusion 40 is matched with the matching hole 50, there is a gap between the third connecting surface 420 and the hole wall of the matching hole 50 to achieve limiting. In some embodiments, the gap on each side ranges from 0.1 mm to 0.3 mm to achieve left and right limiting.

[0057] At least one side of the limiting protrusion 40 is provided with a limiting groove. In some embodiments, the limiting protrusion 40 is provided with limiting grooves on both sides opposite to the matching hole 50, so that the limiting protrusion 40 is in an I-shape, which can play a role of limiting and guiding, and fundamentally prevent the buckle from being broken due to misalignment of the buckle.

[0058] It is understandable that the length of the spring fastener 30 determines the elasticity of the spring fastener 30 , and therefore, the length of the spring fastener 30 can be set according to actual needs and is not specifically limited herein.

[0059] Please continue reading Figure 8 In the present application, the limiting protrusion 40 and the spring fastener 30 provided on the panel 10 cooperate with the matching hole 50 in the middle frame 20 at the same time to realize the connection between the middle frame 20 and the panel 10. This installation method is simple and convenient, can be quickly positioned and installed, and improves the installation efficiency.

[0060] The embodiment of the present application also provides an air conditioner, which includes any of the above-mentioned panels and a middle frame mounting structure. For details, please refer to the above content and will not be repeated here.

[0061] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
