The following description is provided to enable any person skilled in the art to make and use this application. In the following description, details are set forth for the purpose of explanation. It should be understood that those of ordinary skill in the art can realize this application without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of this application with unnecessary details. Therefore, this application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles disclosed in this application.

[0039] For ease of understanding the solution of this application, the spline curves and arrows used for the reference numerals in the drawings are described herein: For the components indicated by the spline curves without arrows, they are solid components, that is, components having a solid structure; for the components indicated by the spline curves with arrows, they are virtual components, that is, components without a solid structure.

[0040] In a first aspect, please refer to Figure 1 , an embodiment of this application provides a grille structure 1, including a switch socket 20 and a grille 10 that are elastically connected. The grille 10 is provided with a mounting groove 11 for accommodating the switch socket 20. The switch socket 20 has a locking portion 21 and an unlocking operation portion 22 that respectively extend outside the mounting groove 11. The locking portion 21 can extend outside the mounting groove 11 under the action of elastic force to be fixedly connected to the panel 2, and the unlocking operation portion 22 is configured to drive the locking portion 21 to retract into the mounting groove 11 to release the fixed connection with the panel 2.

[0041] For the grille structure 1 provided by this application, when it is necessary to connect the grille structure 1 and the panel 2, the unlocking operation portion 22 can be controlled to drive the locking portion 21 to retract into the mounting groove 11. When the grille structure 1 and the panel 2 are aligned, the unlocking operation portion 22 is released, so that the locking portion 21 extends outside the mounting groove 11 under the action of elastic force to be fixedly connected to the panel 2; when it is necessary to disconnect the grille structure 1 and the panel 2, the unlocking operation portion 22 can be controlled to drive the locking portion 21 to retract into the mounting groove 11, so as to realize the disassembly of the grille structure 1; the disassembly and assembly operations of the grille structure 1 provided by this application are simple, time-saving and labor-saving, and only the unlocking operation portion 22 of the switch socket 20 needs to be controlled, avoiding damage to the switch socket 20 caused by cumbersome operations. The switch socket 20 in the grille structure 1 has a simple structure and can realize the stable connection between the grille 10 and the panel 2, with high reliability.

[0042] In some embodiments, please refer to Figure 2 and Figure 3, the installation groove 11 has a first sub-groove portion 111 and a second sub-groove portion 112 that are sequentially connected and inclined. The locking portion 21 can slide out of or retract into the first sub-groove portion 111 along the extending direction of the first sub-groove portion 111, and the unlocking operation portion 22 can slide along the width direction of the second sub-groove portion 112.

[0043] Preferably, in some embodiments, the first sub-groove portion 111 and the second sub-groove portion 112 are perpendicularly arranged. It can be understood that at this time, the width direction of the second sub-groove portion 112 is the extending direction of the first sub-groove portion 111. When the unlocking operation portion 22 slides along the width direction of the second sub-groove portion 112, the locking portion 21 slides along the extending direction of the first sub-groove portion 111.

[0044] In some embodiments, the side of the second sub-groove portion 112 away from the first sub-groove portion 111 is an inclined groove. In other words, for the opening of the second sub-groove portion 112, the side length of the side close to the first sub-groove portion 111 is greater than the side length of the side away from the first sub-groove portion 111. In this way, it is beneficial for the user to operate the unlocking operation portion 22, and it is convenient to control the unlocking operation portion 22 to slide along the width direction of the second sub-groove portion 112, so that the locking portion 21 extends into the installation groove 11.

[0045] In some embodiments, please refer to Figure 4 and Figure 5 , a convex post 12 is provided in the installation groove 11, and a guiding and limiting groove 23 is provided on the switch card seat 20. The convex post is slidably arranged in the guiding and limiting groove 23 along the telescopic direction of the locking portion 21; when the locking portion 21 extends out of the installation groove 11 to be fixedly connected to the panel 2, the convex post 12 abuts against the end wall of the guiding and limiting groove 23 close to the unlocking operation portion 22, and when the locking portion 21 retracts into the installation groove 11 to release the fixed connection with the panel 2, the convex post 12 abuts against the end wall of the guiding and limiting groove 23 close to the locking portion 21.

[0046] In some embodiments, the convex post 12 is a cylinder, and the guiding and limiting groove 23 is an elliptical groove. The cooperation between the cylinder and the elliptical groove makes the operation of the locking portion 21 smoother. It can be understood that the convex post 12 and the guiding and limiting groove 23 can also be other mutually matching shapes.

[0047] Specifically, please refer to Figure 4 , when the unlocking operation portion 22 is pushed downward, at this time, the end wall of the upper end of the guiding and limiting groove 23 of the switch card seat 20 abuts against and limits the convex post 12, which is the maximum stroke position for pushing the switch card seat 20. At this time, the locking portion 21 retracts into the first sub-groove portion 111, and the grille 10 can be opened and move independently. Please refer to Figure 5, when the unlocking operation part 22 is released, the switch socket 20 rebounds upward. At this time, the end wall at the lower end of the guiding and limiting groove 23 of the switch socket 20 abuts against and limits the protruding column 12, which is the maximum stroke position of the rebound of the switch socket 20. At this time, the locking part 21 extends out of the first sub-groove part 111 and extends into the connecting hole 202 of the panel 2, and the grille 10 is closed and stably connected to the panel 2, thereby realizing the opening and closing of the grille 10, that is, the assembly and disassembly of the grille 10 and the panel 2.

[0048] In some embodiments, please refer to Figure 6 The switch socket 20 further includes an elastic arm 24. The elastic arm 24 has good elasticity and can meet the rebound requirements. When the unlocking operation part 22 is pushed and then released, the elastic arm 24 can provide an elastic force to make the locking part 21 extend out of the installation groove 11 to be fixedly connected to the panel 2.

[0049] Furthermore, the shape of the elastic arm 24 is arc-shaped and faces the side close to the unlocking operation part 22.

[0050] The switch socket 20 includes two elastic arms 24, and the two elastic arms 24 are symmetrically arranged on both sides of the guiding and limiting groove 23.

[0051] In some embodiments, please refer to Figure 7 and Figure 8 , first sliding parts 25 are provided on both sides of the locking part 21, second sliding parts 13 are provided on both sides of the first sub-groove part 111, and the first sliding parts 25 and the second sliding parts 13 cooperate to make the locking part 21 slide out of or retract into the first sub-groove part 111 along the extending direction of the first sub-groove part 111. The first sliding parts 25 and the second sliding parts 13 can be components with conventional sliding fits in the art. For example, the first sliding part 25 can be a chute, the second sliding part 13 can be a slide rail, or the first sliding part 25 can be a slide rail while the second sliding part 13 is a chute. The cooperation of the first sliding parts 25 and the second sliding parts 13 makes the locking part 21 run more smoothly when extending out of and retracting into the first sub-groove part 111, and also provides a limiting function.

[0052] In some embodiments, please refer to Figure 9 and Figure 10 , a first limiting clamping column 241 protrudes from the elastic arm 24 along the extending direction away from the locking part 21, a second limiting clamping column 14 protrudes from the installation groove 11 along the extending direction of the locking part 21, the grille structure 1 further includes a spring 15, and the first limiting clamping column 241 and the second limiting clamping column 14 are located inside the spring 15.

[0053] Further, a limit buckle 242 is also provided on the first limit clamping post 241 for fixedly connecting with the spring 15. The elastic arm 24 is prone to deformation and failure after repeatedly compressing and rebounding to reach the fatigue limit and cannot effectively rebound. By adding the spring 15, the resilience can be enhanced and the reliability can be improved. It can be understood that when there are two elastic arms 24, two first limit clamping posts 241 and two second limit clamping posts 14 are respectively provided. Further, when the locking portion 21 extends out of the first sub-groove portion 111, a preset gap is left between the first limit clamping post 241 and the second limit clamping post 14 to prevent the first limit clamping post 241 and the second limit clamping post 14 from abutting against each other and preventing the locking portion 21 from retracting into the first sub-groove portion 111 at this time.

[0054] In some embodiments, the grille structure 1 includes two or more switch card seats 20 to increase the connection stability between the grille 10 and the panel 2.

[0055] In a second aspect, please refer to Figure 11 and Figure 12 , the embodiment of the present application further provides a panel assembly 100, and the panel assembly 100 includes a panel 2 and the above-mentioned grille structure 1. Further, the panel 2 is arranged on the side facing the unlocking operation portion 22.

[0056] In some embodiments, the panel 2 has a connection surface 201. Connection holes 202 are provided on the connection surface 201. The locking portion 21 can extend out of the installation groove 11 under the action of elastic force and extend into the connection holes 202 to be fixedly connected with the panel 2.

[0057] In some embodiments, the plane where the connection surface 201 and the unlocking operation portion 22 are located is parallel. In this way, the unlocking operation portion 22 can be semi-hidden in the connection surface 201 of the panel 2, which is more beautiful.

[0058] In some embodiments, the panel assembly 100 further includes a filter screen 3. The filter screen 3 is located on the side of the grille 10 away from the panel 2, and the filter screen 3 is snap-connected to the grille 10. Specifically, the grille 10 is provided with a buckle 16 and a limit step. When the filter screen 3 is assembled with the grille 10, the filter screen 3 is attached to the grille 10, and the filter screen 3 slides from top to bottom and slides into the buckle 16. When the lower end of the filter screen 3 abuts against the limit step of the grille 10, the filter screen 3 stops sliding and is stably connected to the grille 10 through the buckle 16.

[0059] Further, on the side of the switch card seat 20 close to the filter screen 3, the end surfaces of the guiding limit groove 23 and the elastic arm 24 are located on the same plane and abut against the filter screen 3, and the filter screen 3 can further clamp the switch card seat 20 to prevent the switch card seat 20 from coming out.

[0060] In a third aspect, the embodiment of the present application further provides an air conditioner, and the air conditioner includes the above-mentioned panel assembly 100.

[0061] In some embodiments, the air conditioner is a ceiling-mounted air conditioner.
