[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] In this application, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0053] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0054] Please also read Figure 1 , Figure 2 and Figure 3 , an embodiment of the present application provides a fan coil assembly 1, including a side plate 11 and an end plate 12. The side plate 11 is used to be installed at the end of the main body 13 of the coil assembly, the side plate 11 has a first surface 111 and a second surface 112 opposite to each other, the first surface 111 is closer to the main body 13 of the coil assembly than the second surface 112, the side plate 11 is provided with a positioning hole 113, and the positioning hole 113 passes through the first surface 111 and the second surface 112. The end plate 12 has a third surface 121, and the end plate 12 is provided with a buckle 123. Among them, when the end plate 12 and the side plate 11 are assembled, the third surface 121 fits the first surface 111, and the buckle 123 protrudes from the second surface 112 through the positioning hole 113 and is connected to the side plate 11.

[0055] The fan coil unit assembly 1 may include a main body 13 and a copper tube 14 connected to each other. The main body 13 may be composed of a plurality of fins arranged in sequence. The axial direction of the main body 13 (eg Figure 1The Y direction in the figure is the arrangement direction of the multiple fins. The side plate 11 is installed at the end of the main body 13 of the coil assembly, which means that the installation position of the side plate 11 can be adjacent to the fin at the end and located on the side of the fin at the end away from other fins. The first surface 111 and the second surface 112 of the side plate 11 are both substantially perpendicular to the axial direction of the main body 13, and the first surface 111 of the side plate 11 faces the main body 13, and the second surface 112 faces away from the main body 13.

[0056] It can be understood that when the side plate 11 is in the assembled state, the width direction of the side plate 11 (such as Figure 1 The side plate 11 is perpendicular to the axial direction of the main body 13 (as shown in the X direction), and the width of the side plate 11 in its own width direction is greater than the dimension of the main body 13 in the width direction of the side plate 11, that is, when projected toward the first surface 111 along the axial direction of the main body 13, the projection of the main body 13 completely falls within the range of the first surface 111.

[0057] The positioning hole 113 may be a square hole, a round hole, or a hole of other shapes, which is not limited here.

[0058] When the end plate 12 is in the assembled state, the installation position of the end plate 12 is located between the fin at the end and the side plate 11. It can be understood that the width direction of the end plate 12 is substantially parallel to the width direction of the side plate 11, and the width of the end plate 12 in its own width direction is greater than the width of the side plate 11 in its own width direction, that is, when projected toward the third surface 121 along the axial direction of the main body 13, the projection of the side plate 11 falls within the range of the third surface 121.

[0059] In addition, the connection method of the buckle 123 and the side plate 11 can be connected through the connecting member 15, or can be a clamping method, etc., which is not limited here. It should be noted that the purpose of connecting the buckle 123 and the side plate 11 is to make the end plate 12 and the side plate 11 form a pre-positioned state, that is, after the buckle 123 is connected to the side plate 11, the relative position between the end plate 12 and the side plate 11 is fixed. However, since the load-bearing capacity of the buckle 123 is relatively weak and the main body 13 of the coil assembly is relatively heavy, if the side plate 11 is connected by the buckle 123, that is, the connection between the end plate 12 and the side plate 11 is completed, the buckle 123 may break after installation due to the excessive load, thereby causing the connection formed by the side plate 11 and the main body 13 of the coil assembly to separate from the end plate 12. Therefore, in this embodiment, after the buckle 123 is connected to the side plate 11, other connection relationships exist between the end plate 12 and the side plate 11 to disperse the load borne by the buckle 123 and prevent the buckle 123 from breaking.

[0060] The working principle of this embodiment is:

[0061] First, the side plate 11 is installed on the end of the main body 13 of the coil assembly.

[0062] Then, the end plate 12 is gradually brought closer to the side plate 11 , and the buckles 123 on the end plate 12 are aligned with the positioning holes 113 and passed through until the third surface 121 of the end plate 12 is in contact with the first surface 111 of the side plate 11 .

[0063] Then, the buckle 123 can be conveniently connected to the side plate 11 to form a pre-positioned state between the end plate 12 and the side plate 11 , and then the end plate 12 and the side plate 11 can be connected to complete the assembly of the end plate 12 and the side plate 11 .

[0064] By setting a positioning hole 113 on the side plate 11 and a buckle 123 on the end plate 12, the positioning hole 113 provides a clear guide for the buckle 123, which in turn provides a clear guide for the assembly of the end plate 12, thereby reducing the difficulty of positioning the end plate 12 and the side plate 11 during the assembly process, significantly improving the assembly efficiency of the end plate 12 and the side plate 11, and reducing the time required for assembly.

[0065] The positioning hole 113 ensures that the end plate 12 can be accurately positioned on the side plate 11 during the assembly process. The buckle 123 protrudes from the second surface 112 through the positioning hole 113 and is connected to the side plate 11, so that the end plate 12 and the side plate 11 can form a pre-positioned state, that is, the relative position between the end plate 12 and the side plate 11 is relatively fixed, which effectively prevents the end plate 12 from being offset or misaligned relative to the side plate 11 during the assembly process, thereby ensuring the positioning accuracy and assembly accuracy of the end plate 12 and the side plate 11.

[0066] Since the main body 13 of the coil assembly is heavy, in the prior art, at least two people are required to position and assemble the end plate 12 and the side plate 11 during the assembly process when the side plate 11 without the positioning hole 113 and the end plate 12 without the buckle 123 are assembled, resulting in low assembly efficiency. In the embodiment of the present application, the positioning hole 113 provides a clear guide for the buckle 123, which reduces the difficulty of positioning the end plate 12 and the side plate 11, so that one person can complete the positioning and assembly of the end plate 12 and the side plate 11, saving the manpower required for assembling the fan coil assembly 1.

[0067] In addition, after being connected to the side plate 11 , the buckle 123 can share part of the load formed between the end plate 12 and the side plate 11 , thereby improving the stability of the connection between the end plate 12 and the side plate 11 .

[0068] Please also read Figure 1 , Figure 2 and Figure 4In some embodiments, the side plate 11 is further provided with a first mounting hole 114 penetrating through the second surface 112, and the first mounting hole 114 is spaced apart from the positioning hole 113. The buckle 123 includes a first bent edge 1231 and a second bent edge 1232 connected to each other, and one end of the first bent edge 1231 away from the second bent edge 1232 is connected to the end plate 12, and the second bent edge 1232 is provided with a second mounting hole 1234 penetrating through the second bent edge 1232. Please refer to Figure 5 and Figure 6 , wherein the second mounting hole 1234 is configured to correspond to the first mounting hole 114 when the end plate 12 and the side plate 11 are assembled and is used for the connecting member 15 to pass through so that the buckle 123 is connected to the side plate 11.

[0069] The first mounting hole 114 and the positioning hole 113 are spaced apart to prevent the distance between the hole wall of the side plate 11 forming the first mounting hole 114 and the hole wall forming the positioning hole 113 from being too small, thereby dispersing the stress concentration between the first mounting hole 114 and the positioning hole 113 of the side plate 11, and avoiding the side plate 11 from breaking between the first mounting hole 114 and the positioning hole 113.

[0070] Among them, the first bending edge 1231 protrudes from the third surface 121, so that the second bending edge 1232 protrudes from the third surface 121, so that when the third surface 121 of the end plate 12 is in contact with the first surface 111 of the side plate 11, it is ensured that the second bending edge 1232 can protrude from the second surface 112 through the positioning hole 113.

[0071] In one embodiment, the first mounting hole 114 may be a threaded hole, the axial direction of the first mounting hole 114 is perpendicular to the second surface 112, and the first mounting hole 114 may be a through hole, that is, the first mounting hole 114 may pass through the first surface 111. The second mounting hole 1234 may be a threaded hole that is the same as the first mounting hole 114. The connecting member 15 may be a screw.

[0072] During the assembly process of the end plate 12 and the side plate 11, when the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the second mounting hole 1234 can be made coaxial with the first mounting hole 114, and the connecting member 15 can be threadedly matched with the second mounting hole 1234 and the first mounting hole 114 in turn, thereby realizing the connection between the buckle 123 and the side plate 11.

[0073] In another embodiment, the first mounting hole 114 may be a threaded hole, the axial direction of the first mounting hole 114 is perpendicular to the second surface 112, and the first mounting hole 114 may be a through hole, that is, the first mounting hole 114 may pass through the first surface 111. The second mounting hole 1234 may be a threaded hole that is the same as the first mounting hole 114. The connecting member 15 may be a screw.

[0074] During the assembly process of the end plate 12 and the side plate 11, when the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the second mounting hole 1234 can be made coaxial with the first mounting hole 114, and the connecting member 15 can be threadedly matched with the first mounting hole 114 and the second mounting hole 1234 in turn, thereby realizing the connection between the buckle 123 and the side plate 11.

[0075] In another embodiment, the first mounting hole 114 may be a threaded hole, the axial direction of the first mounting hole 114 is perpendicular to the second surface 112, and the first mounting hole 114 is a blind hole, that is, the first mounting hole 114 does not penetrate the first surface 111. The second mounting hole 1234 may be a threaded hole identical to the first mounting hole 114. The connector 15 may be a screw.

[0076] During the assembly process of the end plate 12 and the side plate 11, when the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the second mounting hole 1234 can be made coaxial with the first mounting hole 114, and the connecting member 15 can be threadedly matched with the second mounting hole 1234 and the first mounting hole 114 in turn, thereby realizing the connection between the buckle 123 and the side plate 11.

[0077] In another embodiment, the first mounting hole 114 may also be other types of holes such as a strip hole. During the assembly process of the end plate 12 and the side plate 11, when the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the second mounting hole 1234 and the first mounting hole 114 can be located at corresponding positions, and the connecting member 15 can cooperate with the first mounting hole 114 and the second mounting hole 1234, thereby realizing the connection between the buckle 123 and the side plate 11.

[0078] In this embodiment, after the end plate 12 and the side plate 11 are initially positioned by the positioning hole 113 and the first bent edge 1231 of the buckle 123, the first mounting hole 114 and the second mounting hole 1234 are used in conjunction with the connecting piece 15 to further initially fix the buckle 123 and the side plate 11, thereby forming a pre-positioning state between the end plate 12 and the side plate 11, making the relative position between the end plate 12 and the side plate 11 relatively fixed, effectively preventing the end plate 12 from being offset or misaligned relative to the side plate 11 during the assembly process, and ensuring the assembly accuracy of the end plate 12 and the side plate 11.

[0079] In addition, the second bent edge 1232 is connected to the side plate 11 via the connector 15 , so that the second bent edge 1232 can share part of the load formed between the end plate 12 and the side plate 11 , thereby improving the stability of the connection between the end plate 12 and the side plate 11 .

[0080] In some other embodiments, the second bent edge 1232 may also be snap-connected with the side plate 11 .

[0081] Please continue reading Figure 1 , Figure 2 and Figure 4 In some more specific embodiments, the second surface 112 is further provided with an avoidance hole 115, which is located on a side of the first mounting hole 114 away from the positioning hole 113. The buckle 123 further includes a third bent edge 1233, which is connected to an end of the second bent edge 1232 away from the first bent edge 1231, and an end of the third bent edge 1233 away from the second bent edge 1232 is closer to the third surface 121 than an end of the third bent edge 1233 connected to the second bent edge 1232. The third bent edge 1233 is configured to be inserted into the avoidance hole 115 when the end plate 12 and the side plate 11 are assembled.

[0082] The avoidance hole 115 may pass through the first surface 111 or may not pass through the first surface 111 , which is not limited herein.

[0083] An end of the third bending edge 1233 away from the second bending edge 1232 is closer to the third surface 121 than an end of the third bending edge 1233 connected to the second bending edge 1232 . In other words, the third bending edge 1233 is bent toward the third surface 121 compared to the second bending edge 1232 .

[0084] In one embodiment, the first mounting hole 114 may be a threaded hole, the axial direction of the first mounting hole 114 is perpendicular to the second surface 112, and the first mounting hole 114 may be a through hole, that is, the first mounting hole 114 may pass through the first surface 111. The second mounting hole 1234 may be a threaded hole that is the same as the first mounting hole 114. The connecting member 15 may be a screw.

[0085] During the assembly process of the end plate 12 and the side plate 11, when the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the third bent edge 1233 can be inserted into the avoidance hole 115, so that the second mounting hole 1234 can be coaxial with the first mounting hole 114. At this time, the connecting piece 15 can be threadedly matched with the second mounting hole 1234 and the first mounting hole 114 in turn, thereby realizing the connection between the buckle 123 and the side plate 11.

[0086] In another embodiment, the first mounting hole 114 may be a threaded hole, the axial direction of the first mounting hole 114 is perpendicular to the second surface 112, and the first mounting hole 114 may be a through hole, that is, the first mounting hole 114 may pass through the first surface 111. The second mounting hole 1234 may be a threaded hole that is the same as the first mounting hole 114. The connecting member 15 may be a screw.

[0087] During the assembly process of the end plate 12 and the side plate 11, when the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the third bent edge 1233 can be inserted into the avoidance hole 115, so that the second mounting hole 1234 can be coaxial with the first mounting hole 114. At this time, the connecting piece 15 can be threadedly matched with the first mounting hole 114 and the second mounting hole 1234 in turn, thereby realizing the connection between the buckle 123 and the side plate 11.

[0088] In another embodiment, the first mounting hole 114 may be a threaded hole, the axial direction of the first mounting hole 114 is perpendicular to the second surface 112, and the first mounting hole 114 is a blind hole, that is, the first mounting hole 114 does not penetrate the first surface 111. The second mounting hole 1234 may be a threaded hole identical to the first mounting hole 114. The connector 15 may be a screw.

[0089] During the assembly process of the end plate 12 and the side plate 11, when the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the third bent edge 1233 can be inserted into the avoidance hole 115, so that the second mounting hole 1234 can be coaxial with the first mounting hole 114. At this time, the connecting piece 15 can be threadedly matched with the second mounting hole 1234 and the first mounting hole 114 in turn, thereby realizing the connection between the buckle 123 and the side plate 11.

[0090] In another embodiment, the first mounting hole 114 may also be other types of holes such as a strip hole. During the assembly process of the end plate 12 and the side plate 11, after the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the third bent edge 1233 can be inserted into the avoidance hole 115, so that the second mounting hole 1234 and the first mounting hole 114 are in corresponding positions. At this time, the connecting member 15 can cooperate with the first mounting hole 114 and the second mounting hole 1234, so as to realize the connection between the buckle 123 and the side plate 11.

[0091] In this embodiment, when the third bending edge 1233 is inserted into the avoidance hole 115, the first positioning hole 113 and the second positioning hole 113 can be made to correspond, that is, the third bending edge 1233 cooperates with the avoidance hole 115 to locate the relative position between the first positioning hole 113 and the second positioning hole 113, and there is no need for the staff to locate the relative position between the first positioning hole 113 and the second positioning hole 113, thereby improving the efficiency of locating the relative position between the first positioning hole 113 and the second positioning hole 113. In addition, when the third bending edge 1233 is inserted into the avoidance hole 115, the third bending edge 1233 and the hole wall of the side plate 11 that forms the avoidance hole 115 abut against each other, so that the third bending edge 1233 can share part of the load between the end plate 12 and the side plate 11, thereby further improving the stability of the connection between the end plate 12 and the side plate 11.

[0092] In some other more specific embodiments, an end of the third bending edge 1233 away from the second bending edge 1232 is farther away from the third surface 121 than an end of the third bending edge 1233 connected to the second bending edge 1232 .

[0093] See also Figure 4 In some more specific embodiments, the third bending edge 1233 is perpendicular to the second bending edge 1232. The first bending edge 1231, the second bending edge 1232 and the third bending edge 1233 meet the following conditions:

[0094] Asinα≥1.5d;

[0095] C≥2d;

[0096]

[0097] Among them, A is the length of the first bending edge 1231, B is the length of the second bending edge 1232, C is the length of the third bending edge 1233, d is the thickness of the first bending edge 1231, the second bending edge 1232 and the third bending edge 1233, α is the angle formed between the first bending edge 1231 and the third surface 121, and β is the angle formed between the second bending edge 1232 and the first bending edge 1231.

[0098] The angle α formed between the first bending edge 1231 and the third surface 121 is in the range of 60° to 90°, and the angle β formed between the second bending edge 1232 and the first bending edge 1231 is in the range of 90° to 135°.

[0099] In one example, the angle α formed between the first bending edge 1231 and the third surface 121 is 75°, the angle β formed between the second bending edge 1232 and the first bending edge 1231 is 115°, the length A of the first bending edge 1231 is 3 mm, the length B of the second bending edge 1232 is 10 mm, the length C of the third bending edge 1233 is 2.5 mm, and the thickness d of the first bending edge 1231, the second bending edge 1232 and the third bending edge 1233 is 0.95 mm.

[0100] The axial direction of the first mounting hole 114 may be perpendicular to the second surface 112 , and the axial direction of the second mounting hole 1234 may be perpendicular to the second bending edge 1232 .

[0101] In one embodiment, the first mounting hole 114 may be a threaded hole, the axial direction of the first mounting hole 114 is perpendicular to the second surface 112, and the first mounting hole 114 may be a through hole, that is, the first mounting hole 114 may pass through the first surface 111. The second mounting hole 1234 may be a threaded hole that is the same as the first mounting hole 114. The connecting member 15 may be a screw.

[0102] During the assembly process of the end plate 12 and the side plate 11, when the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the second bent edge 1232 is inclined relative to the third surface 121, so that the axial direction of the second mounting hole 1234 and the axial direction of the first mounting hole 114 are inclined to each other, and the second bent edge 1232 can be pressed toward the third surface 121, that is, the second bent edge 1232 is exerted toward the third surface 121, so that the third bent edge 1233 is inserted into the avoidance hole 115, and at the same time, the second bent edge 1232 is parallel to the third surface 121, so that the second mounting hole 1234 and the first mounting hole 114 can be coaxial, and at this time, the connecting piece 15 can be threadedly matched with the second mounting hole 1234 and the first mounting hole 114 in sequence, so as to realize the connection between the buckle 123 and the side plate 11.

[0103] In another embodiment, the first mounting hole 114 may be a threaded hole, the axial direction of the first mounting hole 114 is perpendicular to the second surface 112, and the first mounting hole 114 may be a through hole, that is, the first mounting hole 114 may pass through the first surface 111. The second mounting hole 1234 may be a threaded hole that is the same as the first mounting hole 114. The connecting member 15 may be a screw.

[0104] During the assembly process of the end plate 12 and the side plate 11, when the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the second bent edge 1232 is inclined relative to the third surface 121, so that the axial direction of the second mounting hole 1234 is inclined to the axial direction of the first mounting hole 114, and the second bent edge 1232 can be pressed toward the third surface 121, that is, the second bent edge 1232 is exerted toward the third surface 121, so that the third bent edge 1233 is inserted into the avoidance hole 115, and at the same time, the second bent edge 1232 is parallel to the third surface 121, so that the second mounting hole 1234 can be coaxial with the first mounting hole 114, and the connecting piece 15 can be threadedly matched with the first mounting hole 114 and the second mounting hole 1234 in sequence, so as to realize the connection between the buckle 123 and the side plate 11.

[0105] In another embodiment, the first mounting hole 114 may be a threaded hole, the axial direction of the first mounting hole 114 is perpendicular to the second surface 112, and the first mounting hole 114 is a blind hole, that is, the first mounting hole 114 does not penetrate the first surface 111. The second mounting hole 1234 may be a threaded hole identical to the first mounting hole 114. The connector 15 may be a screw.

[0106] During the assembly process of the end plate 12 and the side plate 11, when the buckle 123 protrudes out of the second surface 112 through the positioning hole 113, the second bent edge 1232 is inclined relative to the third surface 121, so that the axial direction of the second mounting hole 1234 and the axial direction of the first mounting hole 114 are inclined to each other, and the second bent edge 1232 can be pressed toward the third surface 121, that is, the second bent edge 1232 is exerted toward the third surface 121, so that the third bent edge 1233 is inserted into the avoidance hole 115, and at the same time, the second bent edge 1232 is parallel to the third surface 121, so that the second mounting hole 1234 and the first mounting hole 114 can be coaxial, and at this time, the connecting piece 15 can be threadedly matched with the second mounting hole 1234 and the first mounting hole 114 in sequence, so as to realize the connection between the buckle 123 and the side plate 11.

[0107] It can be understood that the buckle 123 of the embodiment of the present application has a certain toughness, that is, the first bending edge 1231, the second bending edge 1232 and the third bending edge 1233 can produce a certain deformation ability under the action of external force, so pressing the second bending edge 1232 will not break the buckle 123.

[0108] In some other more specific embodiments, the third bending edge 1233 and the second bending edge 1232 may also be inclined to each other.

[0109] See also Figure 2 In some embodiments, the number of the positioning holes 113 is at least two, and at least two positioning holes 113 are located along the width direction of the side plate 11 (eg Figure 2 The number and distribution positions of the buckles 123 correspond one-to-one with the positioning holes 113.

[0110] It is understandable that if the number of the positioning hole 113 and the buckle 123 is one, when the buckle 123 protrudes from the second surface 112 through the positioning hole 113, the end plate 12 may rotate around the axis of the positioning hole 113, so that the end plate 12 and the side plate 11 are relatively offset, and the purpose of aligning the end plate 12 and the side plate 11 cannot be achieved. Therefore, the number of the positioning holes 113 and the buckle 123 is at least two, and each buckle 123 protrudes from the second surface 112 through the corresponding positioning hole 113 and connects to the side plate 11, so that the end plate 12 and the side plate 11 can be accurately positioned, and the end plate 12 and the side plate 11 can be prevented from being relatively offset.

[0111] In addition, at least two positioning holes 113 are distributed along the width direction of the side plate 11 , which can reduce the difficulty of positioning the end plate 12 and the side plate 11 .

[0112] In some other embodiments, the distribution directions of any two positioning holes 113 may be inclined relative to the width direction of the side plate 11 .

[0113] See also Figure 3 In some embodiments, the end plate 12 further has a fourth surface 122 opposite to the third surface 121, and the end plate 12 is provided with a socket 124 that passes through the third surface 121 and the fourth surface 122, and the closed end of the socket 124 is adjacent to one side edge of the end plate 12, and the open end of the socket 124 passes through the other side edge of the end plate 12 opposite thereto. When the end plate 12 and the side plate 11 are assembled, the main body 13 of the coil assembly is passed through the socket 124.

[0114] It is understood that the open end of the socket 124 forms an opening through the end edge.

[0115] The working principle of this embodiment is:

[0116] First, the side plate 11 is installed on the end of the main body 13 of the coil assembly.

[0117] The end plate 12 is then positioned on the side of the main body 13 of the coil assembly, with the open end of the socket 124 aligned with the main body 13 of the coil assembly.

[0118] See also Figure 7 , and then move the end plate 12 in a direction perpendicular to the axial direction of the main body 13 of the coil assembly so that the main body 13 of the coil assembly passes through the socket 124.

[0119] Please also read Figure 8 and Fig. 9 Then, the end plate 12 is moved axially along the main body 13 of the coil assembly so that the end plate 12 is close to the side plate 11, and the buckle 123 on the end plate 12 is aligned with the positioning hole 113 and passes through until the third surface 121 of the end plate 12 is in contact with the first surface 111 of the side plate 11.

[0120] Please refer again Figure 5 and Figure 6 Then, the buckle 123 can be conveniently connected to the side plate 11 so that the end plate 12 and the side plate 11 form a pre-positioned state, and then the end plate 12 and the side plate 11 can be connected to complete the assembly of the end plate 12 and the side plate 11.

[0121] In some other embodiments, both ends of the socket 124 may be closed ends.

[0122] Please refer again Figure 1 , Figure 2 and Figure 3In some embodiments, a first matching plate 116 is disposed on one side edge of the side plate 11, and the first matching plate 116 is disposed on a first angle rib 1161. A second matching plate 125 is disposed on one side edge of the end plate 12, and the second matching plate 125 is disposed on a second angle rib 1251. When the end plate 12 is assembled with the side plate 11, the second matching plate 125 overlaps the first matching plate 116, and the second angle rib 1251 is embedded in the first angle rib 1161.

[0123] It can be understood that since the main body 13 of the fan coil assembly 1 can be composed of a plurality of fins arranged in sequence and at intervals, when the end plate 12 moves in a direction perpendicular to the axial direction of the main body 13 of the coil assembly so that the main body 13 of the coil assembly is inserted into the socket 124, the closed end of the socket 124 of the end plate 12 may be inserted into the gap between the fins and contact the copper tube 14, thereby possibly causing the copper tube 14 to be cut. In order to solve this problem, in this embodiment, a second mating plate 125 is set on one side edge of the end plate 12, and a first mating plate 116 is set on one side edge of the side plate 11. When the end plate 12 moves in a direction perpendicular to the axial direction of the main body 13 of the coil assembly so that the main body 13 of the coil assembly is inserted into the socket 124, the movement path of the second mating plate 125 in the direction perpendicular to the axial direction of the main body 13 of the coil assembly will interfere with the first mating plate 116. When the second mating plate 125 overlaps the first mating plate 116, the end plate 12 is prevented from continuing to move in a direction perpendicular to the axial direction of the main body 13 of the coil assembly.

[0124] In addition, the end plate 12 may be provided with a plurality of Figure 3 The difference between the distance between the closed end of the limiting socket 124 and the surface of the second matching plate 125 that is attached to the first matching plate 116 and the thickness of the first matching plate 116 is smaller than the distance between the surface of the first matching plate 116 that is attached to the second matching plate 125 and the copper tube 14 closest to the first matching plate 116 in the length direction of the side plate 11.

[0125] The working principle of this embodiment is:

[0126] First, the side plate 11 is installed on the end of the main body 13 of the coil assembly.

[0127] The end plate 12 is then positioned on the side of the main body 13 of the coil assembly, with the open end of the socket 124 aligned with the main body 13 of the coil assembly.

[0128] Then, the end plate 12 is moved in a direction perpendicular to the axial direction of the main body 13 of the coil assembly, so that the main body 13 of the coil assembly is inserted into the socket 124 .

[0129] Then, the end plate 12 is moved axially along the main body 13 of the coil assembly so that the end plate 12 is close to the side plate 11 , and the buckle 123 on the end plate 12 is aligned with the positioning hole 113 and passes through until the third surface 121 of the end plate 12 is in contact with the first surface 111 of the side plate 11 .

[0130] The end plate 12 is then continuously moved in a direction perpendicular to the axial direction of the main body 13 of the coil assembly until the second matching plate 125 overlaps the first matching plate 116 and the second corner rib 1251 is embedded in the first corner rib 1161 .

[0131] Then, the buckle 123 is connected to the side plate 11 so that the end plate 12 and the side plate 11 are in a pre-positioned state, and then the end plate 12 and the side plate 11 can be connected to complete the assembly of the end plate 12 and the side plate 11.

[0132] In this embodiment, the first corner rib 1161 can enhance the bending resistance of the first mating plate 116, and the second corner rib 1251 can enhance the bending resistance of the second mating plate 125. The second corner rib 1251 is embedded in the first corner rib 1161, and can cooperate with the positioning method formed between the positioning hole 113 and the buckle 123 to further improve the positioning accuracy and assembly accuracy of the end plate 12 and the side plate 11.

[0133] In some other embodiments, the first corner rib 1161 may also be embedded in the second corner rib 1251 .

[0134] See also Fig.10 In some embodiments, the side plate 11 has an installation area for installing the copper tube 14, and the end plate 12 and the second matching plate 125 have installation positions for installing the two components. The main body 13, the side plate 11 and the end plate 12 of the fan coil unit assembly 1 meet the following conditions:

[0135] N>K;

[0136] ML>K;

[0137] Among them, L is the length of the main body 13, M is the length of the side plate 11, K is the length of the installation position, and N is the length difference between the surface of the first matching plate 116 attached to the second matching plate 125 and the position of the installation area closest to the first matching plate 116.

[0138] Please also read Figure 2 and Figure 3 In some more specific embodiments, the first matching plate 116 extends along the width direction of the side plate 11, and the first angle rib 1161 is located in the middle of the first matching plate 116 in the width direction of the side plate 11. The second matching plate 125 extends along the width direction of the end plate 12, and the second angle rib 1251 is located in the middle of the second matching plate 125 in the width direction of the end plate 12.

[0139] The first corner rib 1161 is located in the middle of the first matching plate 116 in the width direction of the side plate 11, which can enhance the bending resistance of the first matching plate 116 so that the bending resistance of the first matching plate 116 on both sides of the corner rib in the width direction is roughly the same.

[0140] Similarly, the second corner rib 1251 is located in the middle of the second mating plate 125 in the width direction of the end plate 12, which can enhance the bending resistance of the second mating plate 125 so that the bending resistance of the second mating plate 125 on both sides of the corner rib in the width direction is roughly the same.

[0141] In some other more specific embodiments, the position of the first corner rib 1161 may be offset relative to the middle position of the first matching plate 116 , and the position of the second corner rib 1251 may be offset relative to the middle position of the second matching plate 125 .

[0142] Please refer again Figure 2 In some embodiments, the second surface 112 is further provided with two protrusions 117, both of which are along the length direction of the side plate 11 (eg Figure 2 The two protrusions 117 extend in the Z direction of the side plate 11, and the two protrusions 117 are adjacent to the two side edges of the side plate 11 in the width direction of the side plate 11.

[0143] The two protrusions 117 extending along the length direction of the side plate 11 can enhance the bending resistance of the side plate 11 in the length direction.

[0144] In some other embodiments, the number of the protrusions 117 may be greater than two.

[0145] In a second aspect, an embodiment of the present application further discloses an air conditioner (not shown in the figure), comprising the above-mentioned fan coil assembly 1.

[0146] The air conditioner including the fan coil unit assembly 1 can improve the efficiency of the air conditioner installation and avoid the problem of water leakage caused by the end plate 12 cutting the copper tube 14.

[0147] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
