Description

Technical Field

[0001] The invention relates to the field of air conditioning equipment, and in particular to a display panel buckling structure. Background Art

[0002] At present, the installation of the air conditioner display box is performed by fixing with screws on the one hand and by snapping the display box into place by lateral movement on the other hand.

[0003] The structure of fixing with screws is simple and reliable, but it needs to be implemented by tools, which is inconvenient and increases materials and process hours, thereby increasing costs. Therefore, it is difficult to make the display box and the panel fit well when fixing with screws.

[0004] The installation is achieved by lateral movement of the display box, usually by using the spring buckle of the display box bottom plate to abut against the triangular rib on the base plate. However, the rigidity of the spring buckle is relatively small, and after multiple operations, the spring buckle will deform, resulting in unstable assembly of the display box. In special scenarios, such as falling, the buckle deformation and bending will be more obvious.

[0005] Therefore, it is necessary to further improve the installation of the display box. Summary of the invention

[0006] Compared with the prior art, this application has the following characteristics:

[0007] In order to solve at least one of the above problems, the present invention provides a display panel mounting structure, including a first buckling portion, a first limiting portion and a second buckling portion arranged on the display panel, wherein the first buckling portion and the second buckling portion are buckled with each other up and down, and the first limiting portion and the second buckling portion are abutted against a side of the display panel, wherein a side of the first buckling portion away from the display panel is closer to the display panel than a side of the second buckling portion away from the display panel.

[0008] Compared with the prior art, this structure is used to achieve the installation of the display panel. Since the first limiting portion abuts against the side of the second buckling portion close to the display panel, that is, the limiting is achieved by the mutual abutment between the first limiting portion and the second buckling portion, and the side of the first buckling portion away from the display panel is closer to the display panel than the side of the second buckling portion away from the display panel, that is, the left end of the first buckling portion does not reach the left end of the second limiting portion, that is, the first buckling portion does not contact the triangular rib, thereby ensuring the quality and life of the first buckling portion. In addition, the installation is carried out by floating up and down, which is convenient and fast to load and unload without increasing labor costs.

[0009] Furthermore, the end of the second buckling portion that first contacts the first buckling portion when buckled has a first guide portion.

[0010] Furthermore, the first buckling portion is a pair of elastic buckles, and the openings formed by the elastic buckles face the substrate.

[0011] Furthermore, the elastic buckle is U-shaped, and the opening direction of the U-shaped elastic buckle is toward the substrate.

[0012] Furthermore, the inner side spacing between the two U-shaped elastic buckles is at least 2 mm smaller than the maximum width of the end of the second buckling portion.

[0013] Furthermore, the second buckling portion is a boss, and one end of the boss away from the substrate has a chamfer.

[0014] Furthermore, the first limiting portion is a limiting rib, the limiting rib is arranged on the display panel, and the width of the limiting rib is greater than the width of the first buckling portion.

[0015] Furthermore, an end of the first buckling portion is higher than the display panel, and an end of the second buckling portion is higher than the substrate.

[0016] Further, the substrate is provided with a receiving groove, the second buckling portion is located in the receiving groove, and the first buckling portion and the second buckling portion are both received in the receiving groove when buckled.

[0017] Furthermore, the U-shaped elastic buckle is connected to the display panel through reinforcing ribs and reinforcing tendons.

[0018] Furthermore, a rib is provided inside the U-shape of the U-shaped elastic buckle.

[0019] Furthermore, a spaced plug-in portion is provided on one side of the display panel opposite to the first buckling portion, and a slot is provided at a corresponding position of the substrate, and the plug-in board can float up and down in the slot.

[0020] Furthermore, the second buckling portion further includes a guide plate, and the elastic buckle can slide up and down along the guide plate.

[0021] Furthermore, the second buckling part further includes a second guide part, and the second guide part is synchronously guided with the slot. Furthermore, the vertical floating installation structure of the display panel further includes a switch, and the switch is arranged on the display panel and located on a side opposite to the first buckling part.

DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Abutment in this article refers to direct contact.

[0032] like Figure 1-2 As shown in Figures 4 and 5, a display panel 1 installation structure includes a first buckling portion 11, a first limiting portion 12 and a second buckling portion 21 arranged on the display panel 1, wherein the first buckling portion 11 is buckled with the second buckling portion 21, and the first limiting portion 12 abuts against a side of the second buckling portion 21 close to the display panel 1, that is, the first limiting portion 12 and the right end of the second buckling portion 21 abut against each other to achieve limitation, wherein the side of the first buckling portion 11 away from the display panel 1 is closer to the display panel 1 than the side of the second buckling portion 21 away from the display panel 1, that is, the left end of the first buckling portion 11 does not reach the left end of the second limiting portion.

[0033] This structure is used to install the display panel 1. The first limiter is used for limiting. Since the triangular rib 22 is arranged at the right end of the boss, the first buckling portion 11 does not contact the triangular rib 22. Figure 3As shown, there is a certain distance between the end of the first buckle part 11 and the triangular rib 22, and the distance is at least 2 mm. Through this arrangement, the quality and life of the first buckle part 11 are guaranteed. In addition, the installation is carried out by floating up and down, which is convenient and fast to load and unload without increasing labor costs.

[0034] The substrate 2 may be a middle frame, a wiring cover, or an electric control box cover. In this embodiment, it is an electric control box cover.

[0035] Specifically, the first buckle 11 can be an elastic buckle, or a hook or a staple, etc., preferably an elastic buckle. If it is an elastic buckle, at least one pair is required, and the opening formed by the elastic buckle faces the substrate 2. This arrangement is mainly to achieve up and down floating installation, that is, when installing, align the opening of the elastic buckle with the second buckle 21 and press down to achieve installation. Among them, the use of elastic material can enhance toughness and increase its service life; at the same time, the buckle structure is easy to install and avoids damage to other components during transportation due to hooking and nailing.

[0036] In another embodiment, the elastic buckle is a U-shaped elastic buckle 16, and the opening direction of the U-shaped elastic buckle 16 is toward the substrate 2. The adjacent U-shaped edges of the two U-shaped elastic buckles 16 are used to buckle with the second buckling portion 21. The U-shaped structure can improve stability while utilizing the elastic deformation of one side during the buckling process.

[0037] like Figure 6-7 As shown, in another embodiment of the present invention, the U-shaped elastic buckle 16 can be further connected to the display panel 1 or the first position-limiting portion 12 by using the reinforcing ribs 13 and the reinforcing ribs 15, and the stability can be further improved by using a structure of multiple reinforcing ribs 13 and reinforcing ribs 15. If a single buckle is selected, it is not convenient to deform when connected with the reinforcing rib 13.

[0038] Continue to see Figure 6-7 In another embodiment of the present invention, a rib plate 14 is provided inside the U-shape of the U-shaped elastic buckle 16. By providing the rib plate 14, the elasticity and strength of the U-shaped elastic buckle 16 can be enhanced to prevent it from breaking and deforming during the clamping process.

[0039] In another embodiment, the distance between the inner sides of the two U-shaped elastic buckles is at least 2 mm smaller than the maximum width of the end of the second buckling portion 21. In other words, the distance between two adjacent U-shaped edges between the two U-shaped elastic buckles is recorded as the first distance, wherein the two U-shaped edges do not belong to the same U-shaped elastic buckle; the maximum width of the second buckling portion 21 is recorded as the second distance, and the first distance is at least 2 mm smaller than the second distance. This arrangement can prevent installation errors, which may cause the second buckling portion 21 to be directly inserted into the U-shaped groove, causing direct damage to the first buckling portion 11.

[0040] like Figure 5 As shown, in another embodiment, the end portion that first contacts the second snap-fitting portion 21 when snapping with the first snap-fitting portion 11 has a first guide portion 211, that is, the end portion of the second snap-fitting portion 21 away from the substrate 2 has a first guide portion 211. By providing the first guide portion 211, the transitional snap-fitting between the first snap-fitting portion 11 and the second snap-fitting portion 21 is achieved, thereby reducing friction, improving installation efficiency, and avoiding deformation and wear of the first snap-fitting portion 11.

[0041] like Figure 5 As shown, the second buckling portion 21 further includes a guide plate 212 , and the elastic buckle 16 can slide up and down along the guide plate 212 .

[0042] like Figure 5 As shown, in another embodiment, the second buckling portion 21 may be a boss, a cylinder or a hook with a hanging point, or a plate with holes for accommodating a staple. The second buckling portion 21 is preferably a boss, and the end of the boss away from the substrate 2 has a chamfer. The chamfer may be a slope extending downward from the top, and the top refers to the end away from the substrate 2. The second buckling portion 21 is set as a chamfered boss, which can facilitate the buckling with the first buckling portion 11.

[0043] like Figure 6 As shown, in another embodiment, the first limiting portion 12 is a limiting rib, and the limiting rib is arranged on the display panel 1, and the width of the limiting rib is greater than the width of the first buckling portion 11. The width of the first buckling portion 11 mentioned here refers to the maximum distance between the two side edges in the width direction of the first buckling portion 11. At the same time, considering the cost issue, the width of the limiting rib does not need to be much wider, just slightly wider, that is, the limiting rib on both sides in the width direction is 1-2mm wider than the side edges of the first buckling portion 11. This arrangement can improve the overall stability of the first limiting portion 12 and the limiting rib.

[0044] In another embodiment of the present invention, the end of the first buckling portion 11 is higher than the display panel 1, and the end of the second buckling portion 21 is higher than the substrate 2. The ends mentioned here are all ends away from the substrate 2. On the one hand, in order to reduce the space occupied by the buckling portion, and on the other hand, in order to achieve the buckling of the first buckling portion 11 and the second buckling portion 21, if the second buckling portion 21 is lower than the substrate 2, the first buckling portion 11 will not be able to buckle with it.

[0045] In order to save space and reduce the thickness of the air conditioner, in another embodiment of the present invention, the base includes a receiving groove 23, the second buckling portion 21 is located in the receiving groove 23, and when the first buckling portion 11 and the second buckling portion 21 are buckled, both are located in the receiving groove 23.

[0046] In another embodiment, if Figure 1 As shown, the display panel 1 is provided with a spaced plug-in portion 17 on the side opposite to the first buckle portion 11, and the substrate 2 is provided with a slot at a corresponding position, and the plug-in plate can float up and down in the slot. The plug-in plate is located on the display panel 1. By correspondingly arranging the plug-in portion 17 and the slot, the installation can be limited and the floating can be guided. The number of the plug-in portion 17 is not limited, and can be 2, 3 or more. Based on the comprehensive consideration of cost and effect, 2 are preferred.

[0047] In another embodiment, the second buckling portion 21 further includes a second guiding portion, and the second guiding portion and the slot are guided synchronously, so as to ensure that the display panel 1 as a whole floats up and down.

[0048] In another embodiment, the vertical floating installation structure of the display panel 1 further comprises a switch (18), which is arranged on the display panel 1 and located on a side opposite to the first buckling portion 11. The button is arranged on the side to prevent the light panel from floating down without being subjected to force when pressed, and to prevent accidental touch.

[0049] Another embodiment provides an air conditioning device, which has a housing and the display panel mounting structure described in any of the above embodiments.

[0050] Although the present invention is disclosed as above, the present invention 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 present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
