[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related technologies:

[0005] The width of the body of the wire pressing plate is relatively narrow, and the buckles are arranged at both ends of the wire pressing plate. Since the length of the wire pressing plate is relatively long, it is easy to cause deformation of the wire pressing plate during the installation process when the wire pressing plate is inserted.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present application. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art. Utility Model Content

[0007] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below.

[0052] It should be noted that, without conflict, the embodiments in this disclosure and the features in the embodiments may be combined with each other.

[0053] Embodiment 1:

[0054] Combined with Figure 1-7 As shown, the present disclosure embodiment provides a wire pressing plate 10 for an air conditioner. The wire pressing plate 10 is used for an indoor unit. The indoor unit includes a chassis 20 and a motor 30.

[0055] The motor 30 is arranged on the chassis 20. The wire pressing plate 10 is installed on the chassis 20, and the surface of the wire pressing plate 10 facing the chassis 20 and the chassis 20 together enclose a wire routing groove 31 for the motor wire to pass through. Among them, the motor wire is connected to the motor 30.

[0056] Among them, as Figure 7 shown, along the direction away from the motor 30, the surface of the wire pressing plate 10 facing the chassis 20 (as shown at point F in Figure 1 ) slopes downward.

[0057] The wire pressing plate 10 is installed on the chassis 20. The wire pressing plate 10 and the chassis 20 together enclose a wire routing groove 31 for the motor wire to pass through. The wire pressing plate 10 fixes the motor wire in the wire routing groove 31. Among them, the wire pressing plate 10 is designed as an inclined structure. One end of the wire pressing plate 10 in the direction close to the motor 30 is higher than one end of the wire pressing plate 10 in the direction away from the motor 30. Water can flow in the direction away from the motor 30 under the action of its own gravity, resulting in water not approaching the motor 30. In this way, water cannot drip on the motor 30 terminals, thereby preventing the motor 30 from short - circuiting, improving safety, and reducing the after - sales maintenance cost caused by short - circuiting.

[0058] Optionally, as Figure 7 shown, along the direction away from the motor 30, the surface of the wire pressing plate 10 facing the chassis 20 gradually slopes downward.

[0059] The wire pressing plate 10 is high in the direction close to the motor 30 and low in the direction away from the motor 30, making the wire pressing plate 10 have an inclined structure on the bottom plate and a gradually inclined structure. This makes the water flow more smoothly along the wire pressing plate 10 in the direction away from the motor 30. In this way, water can be discharged from the wire routing groove 31 in time, so that the wire pressing plate 10 plays a role in protecting the motor 30.

[0060] Optionally, as Figure 2 shown, a groove 1024 is formed by the depression of the surface of the wire pressing plate 10 facing the chassis 20. The groove 1024 and the chassis 20 together define the wire routing groove 31. Among them, along the direction away from the motor 30, the surface of the bottom wall 1021 of the groove 1024 facing the chassis 20 slopes downward.

[0061] The surface of the wire pressing plate 10 facing the chassis 20 is recessed to form a groove 1024 with an opening facing the chassis 20. The groove 1024 includes a groove bottom wall 1021, a first groove side wall 1022, and a second groove side wall 1023. The first groove side wall 1022 and the second groove side wall 1023 are provided on opposite sides of the groove bottom wall 1021. The groove bottom wall 1021 and the first groove side wall 1022 are connected and a first bend 2043 is formed at the connection, and the groove bottom wall 1021 and the second groove side wall 1023 are connected and a second bend 1053 is formed at the connection.

[0062] The air conditioner can be an embedded air conditioner. In this case, the chassis 20 is installed on the ceiling and is provided above the wire pressing plate 10. Along the direction away from the motor 30, the surface of the groove bottom wall 1021 of the groove 1024 facing the chassis 20 (i.e., the upper surface of the groove bottom wall 1021 of the groove 1024) slopes downward, so that the water flowing into the groove 1024 can only flow out along the groove bottom wall 1021 to the lower place (the direction away from the motor 20), thus preventing water droplets from dripping onto the motor 30, avoiding short - circuit of the motor circuit, improving safety, and reducing the after - sales maintenance cost caused by short - circuit.

[0063] Optionally, along the direction close to the groove bottom wall 1021 of the groove 1024, the surface of the groove side wall 1021 of the groove 1024 facing the chassis 20 slopes downward to form a guiding surface.

[0064] The groove side walls of the groove 1024 include a first groove side wall 1022 and a second groove side wall 1023. Along the direction close to the groove bottom wall 1021 of the groove 1024, the surface of the first groove side wall 1022 and / or the second groove side wall 1023 facing the chassis 20 slopes downward to form a guiding surface, and the guiding surface has a guiding effect on the water flow. An angle greater than 90 degrees is formed between the groove side wall and the groove bottom wall 1021. In this way, when water droplets hit the groove side wall, the water will flow along the guiding surface to the groove bottom wall 1021 under the action of its own gravity, and then flow along the groove bottom wall 1021 in the direction away from the motor 30, avoiding the water flowing to the motor 30.

[0065] Optionally, the chassis 20 is provided with a connection and cooperation part, and the wire pressing plate 10 is provided with a connection part connected to the connection and cooperation part. The connection and cooperation part cooperates with the connection part to position the wire pressing plate 10 on the chassis 20.

[0066] Optionally, the connection and cooperation part includes a first connection and cooperation part 201 and a second connection and cooperation part 202 provided on the chassis 20, and the connection part includes a first connection part 103 connected to the first connection and cooperation part 201 and a second connection part 104 connected to the second connection and cooperation part 202 provided on the wire pressing plate 10; wherein, the first connection part 103 and the second connection part 104 are respectively located on opposite sides of the wire routing groove 31.

[0067] As Figure 5As shown, the positioning between the wire pressing plate 10 and the chassis 20 is achieved through the cooperation of the first connecting portion 103 and the first connecting and mating portion 201, and the cooperation of the second connecting portion 104 and the second connecting and mating portion 202.

[0068] The first connecting portion 103 and the second connecting portion 104 are respectively located on opposite sides of the wire routing groove 31, and the first connecting and mating portion 201 and the second connecting and mating portion 202 are also located on opposite sides of the wire routing groove 31, so that the wire pressing plate 10 is uniformly stressed at opposite sides of the wire routing groove 31, improving the stability and reliability of the connection between the wire pressing plate 10 and the chassis 20.

[0069] Optionally, as Figure 1 and Figure 2 shown, the wire pressing plate 10 of the air conditioner includes a wire bundling portion 110 and an extension portion 1103.

[0070] The wire bundling portion 110 and the chassis 20 jointly enclose the wire routing groove 31, and the wire bundling portion 110 includes the bottom wall 1021 of the groove and the groove side wall.

[0071] The extension portion is provided on one side of the wire bundling portion 110, and along the width direction of the wire routing groove 31, the extension portion and the wire bundling portion 110 are arranged in sequence.

[0072] Wherein, along the direction away from the motor 30, the surface of the extension portion facing the chassis 20 slopes downward, or, along the direction close to the wire routing groove 31, the surface of the extension portion facing the chassis 20 slopes downward and is higher than the wire bundling portion 110.

[0073] When the surface of the extension portion facing the chassis 20 (the upper surface of the extension portion) slopes downward along the direction away from the motor 30, the water droplets falling on the surface of the extension portion facing the chassis 20 will flow in the direction away from the motor 30 under the action of their own gravity, avoiding the water flowing towards the motor 30.

[0074] It can also be that along the direction close to the wire routing groove 31, the surface of the extension portion facing the chassis 20 slopes downward and is higher than the wire bundling portion 110. In this way, the height of the extension portion near the wire bundling portion 110 is lower than the height of the extension portion far from the wire bundling portion 110. The water droplets falling on the extension portion will flow towards the wire bundling portion 110 under the action of their own gravity, and thus flow into the wire bundling portion and flow along the bottom wall 1021 of the groove in the direction away from the motor 30.

[0075] Taking the connection method of the connecting portion and the connecting and mating portion as screw connection as an example, the water on the ceiling will flow through the screw holes (connecting and mating portions) on the chassis 20 and the screw holes (connecting portions) on the wire pressing plate 10 to the extension portion, and the water flowing into the extension portion will flow in the direction away from the motor 30 along the inclined direction of the extension portion.

[0076] The extension part 110 includes a first extension part 1101 and a second extension part 1102. The first extension part 1101 is disposed on one side of the wire bundling part 110, and the first connection part 103 is disposed on the first extension part 1101; the second extension part 1102 is disposed on the other side of the wire bundling part 110, and the second connection part 104 is disposed on the second extension part 1102.

[0077] Wherein, along the direction away from the motor 30, the surface of the first extension part 1101 and / or the second extension part 1102 is inclined downward toward the surface of the chassis 20, or, along the direction close to the wire routing groove 31, the surface of the first extension part 1101 and / or the second extension part 1102 is inclined downward toward the surface of the chassis 20 and is higher than the wire bundling part 110.

[0078] Optionally, as Figure 3 shown, the wire pressing plate 10 is provided with a wire dividing groove 303, and the wire dividing groove 303 is communicated with the wire routing groove 31.

[0079] The wire pressing plate 10 is provided with a wire dividing groove 303, and the wire dividing groove 303 is disposed on the second extension part 1102.

[0080] The second connection and cooperation part 201 includes a first sub-connection and cooperation part 2021 and a second sub-connection and cooperation part 2022. The second connection part 104 includes a first sub-connection part 1041 and a second sub-connection part 1042. The first sub-connection and cooperation part 2021 is matched with the first sub-connection part 1041, such as screw connection or snap connection. The second sub-connection and cooperation part 2022 is matched with the second sub-connection part 1042, such as screw connection or snap connection.

[0081] The first sub-connection part 1041 and the second sub-connection part 1042 are disposed on opposite sides of the wire dividing groove 303. The wire dividing groove 303 is in an arch shape. The wire dividing groove 303 is communicated with the wire routing groove 31. The wire routing groove 31 passes through the motor wire. After the motor wire enters from the first end 301 of the wire routing groove 31, it is divided into two parts. One part extends out from the second end 302 of the wire routing groove 31, and the other part can extend out from the wire dividing groove 303.

[0082] It can also be that after the motor wire enters from the second end 302 of the wire routing groove 31, it is divided into two parts. One part extends out from the first end 301 of the wire routing groove 31, and the other part can extend out from the wire dividing groove 303.

[0083] Optionally, the embodiment of the present disclosure further provides an air conditioner, including an indoor unit. The indoor unit includes a chassis 20, a motor 30, and the wire pressing plate 10 for an air conditioner as described in any one of the above embodiments.

[0084] The motor 30 is disposed on the chassis 20. The wire pressing plate 10 is mounted on the chassis 20. The surface of the wire pressing plate 10 facing the chassis 20 and the chassis 20 jointly enclose a wire routing groove 31 for the motor wire to pass through.

[0085] The air conditioner provided by this application includes the wire pressing plate as described in any one of the above embodiments, and thus has all the beneficial effects of the wire pressing plate as described in any one of the above embodiments, which will not be elaborated here.

[0086] Optionally, the motor 20 is arranged in the middle of the chassis 20. The chassis 20 is provided with a plurality of reinforcing ribs 32. At least part of the wire pressing plate 10 is arranged between two adjacent reinforcing ribs 32, and together with the part of the chassis 20 located between two adjacent reinforcing ribs 32, a wire routing groove 31 is defined, so that the arrangement of the wire pressing plate 10 does not affect the arrangement of the reinforcing ribs 32 on the chassis, does not damage the strength of the reinforcing ribs 32, and reasonably utilizes the space between two adjacent reinforcing ribs 32.

[0087] As Figure 16 shown, a plurality of reinforcing ribs 32 are radially distributed around the motor 30, which can improve the structural strength of each part of the chassis 20.

[0088] At least part of the wire pressing plate 10 is provided with reinforcing ribs 32 to increase the structural strength of the chassis 20. The reinforcing ribs 32 on the chassis 20 can be integrally formed by stamping, with simple process and convenient manufacturing.

[0089] The chassis 20 is provided with a first connection and cooperation part 201 and a second connection and cooperation part 202. The first connection and cooperation part 201 is connected to the first connection part 103, and the second connection and cooperation part 202 is connected to the second connection part 104. Among them, the first connection and cooperation part 201 is arranged on the reinforcing rib 32, and the second connection and cooperation part 202 is arranged on the reinforcing rib 32 adjacent to the reinforcing rib 32 where the first connection and cooperation part 201 is located.

This positioning method is simple and easy to operate, does not require screwing, and has high production efficiency.

[0095] The positioning portion 204 can also be provided on the wire pressing plate 10. When the positioning portion 204 is provided on the wire pressing plate 10 and the buckle 105 is provided on the chassis 20, when the buckle 105 can move relative to the slot 203 in the first direction to the limiting position, the buckle 105 cooperates with the positioning portion 204 to limit the position of the wire pressing plate 10 relative to the chassis 20. When the positioning portion 204 is provided on the wire pressing plate 10 and the slot 203 is provided on the chassis 20, when the buckle 105 can move relative to the slot 203 in the first direction to the limiting position, the slot 203 cooperates with the positioning portion 204 to limit the position of the wire pressing plate 10 relative to the chassis 20, realizing the positioning of the wire pressing plate 10 relative to the chassis 20. This positioning method is simple and easy to operate, does not require screwing, and has high production efficiency.

[0096] Wherein, the number of the buckle 105 or the slot 203 provided on the wire pressing plate 10 is one or more. When there are multiple ones, the multiple buckles 105 or slots 203 are arranged opposite to each other in sequence along the length direction of the wire pressing plate 10. Among them, the number of the buckle 105 and the slot 203 is equal and they correspond to each other one by one.

[0097] Optionally, at the limiting position, the buckle 105 or the slot 203 cooperates with the positioning portion 204 to limit the movement of the buckle 105 relative to the slot 203 in the second direction, wherein the second direction is opposite to the first direction. As Figure 26 shown, a buckle is provided on the wire pressing plate, a positioning portion and a slot are provided on the chassis, and the buckle is in the limiting position.

[0098] In the limiting position, taking the example that the chassis 20 is provided with a positioning portion 204 and the wire pressing plate 10 is provided with a buckle 105, as Figure 24 shown, when the buckle 105 moves in the first direction to approach the positioning portion 204, the buckle 105 cooperates with the positioning portion 204, and can limit the movement of the buckle 105 relative to the card slot 203 in the second direction, that is, can limit the movement of the buckle 105 in the direction away from the positioning portion 204, and prevent the buckle 105 from disengaging from the positioning portion 204.

[0099] As Figure 26 shown, the first direction is the direction from the card slot 203 to the positioning portion 204, and is also the direction from the end of the card slot 203 far from the positioning portion 204 to the end close to the positioning portion 204.

[0100] Optionally, the card slot 203 extends along the length direction of the wire routing groove 31, and the buckle 105 moves relative to the card slot 203 along the length direction of the card slot 203; when the positioning portion 204 is provided on the chassis 20, the positioning portion 204 and the buckle 105 or the card slot 203 provided on the chassis 20 are arranged in sequence along the length direction of the card slot 203; when the positioning portion 204 is provided on the wire pressing plate 10, the positioning portion 204 and the buckle 105 or the card slot 203 provided on the wire pressing plate 10 are arranged in sequence along the length direction of the card slot 203.

[0101] The card slot extends along the length direction of the wire routing groove 31, and the buckle 105 moves relative to the card slot 203 along the length direction of the card slot 203. In this way, after the buckle 105 is inserted into the card slot 203, it moves relative to the card slot 203 along the length direction of the wire routing groove 31 to move to the limiting position. That is, during the installation process of assembling the wire pressing plate 10 onto the chassis 20, after the buckle 105 is inserted into the card slot 203, the wire pressing plate 10 moves relative to the chassis 20 along the length direction of the wire routing groove 31, avoiding interference between the wire pressing plate 10 and the chassis 20 during the movement process.

[0102] For example, the positioning portion 204 and the card slot 203 are provided on the chassis 20, the buckle 105 is provided on the wire pressing plate 10, the positioning portion 204 and the buckle 105 or the card slot 203 provided on the chassis 20 are arranged in sequence along the length direction of the card slot 203. When the buckle 105 is inserted into the card slot 203 and moves in the direction of the positioning portion 204, the buckle 105 moves along the length direction of the card slot 203. When it moves to the limiting position, the buckle 105 cooperates with the positioning portion 204, so that the wire pressing plate 10 is fixed on the chassis, which is convenient for installation, improves the installation efficiency and reduces the cost.

[0103] For another example, a card slot 203 and a positioning portion 204 are provided on a wire pressing plate 10, a buckle 105 is provided on a chassis 20, the positioning portion 204 and the buckle 105 or the card slot 203 provided on the wire pressing plate 10 are sequentially arranged along the length direction of the card slot 203. The buckle 105 is inserted into the card slot 203. When the buckle 105 moves towards the positioning portion 204, the buckle 105 moves along the length direction of the card slot 203. When it moves to the limit position, the buckle 105 cooperates with the positioning portion 204, so that the wire pressing plate 10 is fixed on the chassis 20, which is convenient for installation, improves the installation efficiency and reduces the cost.

[0104] Optionally, as Figure 26 shown, the positioning portion 204 includes a positioning protrusion 33. At the limit position, the buckle 105 abuts against the positioning protrusion 33 to limit the movement of the buckle 105 relative to the card slot 203 in the second direction.

[0105] As Figure 24 shown, the positioning protrusion 33 includes a first positioning section 331 and a second positioning section 332.

[0106] The first positioning section 331 and the second positioning section 332 are sequentially arranged along the first direction. The first positioning section 331 and the second positioning section 332 are connected and a first bend 208 is formed at the connection. The positioning protrusion 33 can be in a triangular structure.

[0107] As Figure 24 shown, the first bend 208 is a structure that bulges upward or can also be a structure that depresses downward.

[0108] Wherein, at the limit position, the buckle 105 abuts against the first bend 208 and / or abuts against the second positioning section 332.

[0109] The positioning portion 204 includes a positioning protrusion 33. When at the limit position, the buckle abuts against the first bend 208 and / or abuts against the second positioning section 332, which can limit the movement of the buckle 105 relative to the card slot 203 in the second direction, prevent the buckle 105 from separating from the positioning portion 204, and can also limit the movement of the buckle 105 towards the wire trough 31, so that the connection between the wire pressing plate 10 and the chassis 20 is more firmly clamped.

[0110] Optionally, as Figure 24 shown, along the first direction, the second positioning section 332 is inclined towards the direction away from the buckle 105.

[0111] The buckle 105 includes a first clamping portion 1051. At the limit position, the first clamping portion 1051 abuts against the second positioning section 332, and the inclination direction is the same as that of the second positioning section 332.

[0112] The first clamping portion 1051 is provided on the surface of the buckle 105 facing the second positioning section 332. The inclination directions of the second positioning section 332 and the first clamping portion 1051 are such that at the limiting position, the second positioning section 332 can restrict the movement of the buckle 105 in the second direction. Moreover, the first clamping portion 1052 has the same inclination direction as the second positioning section 332, so that the contact area between the first clamping portion 1051 and the second positioning section 332 is increased. The surfaces of the first clamping portion 1051 for abutting against the second positioning section 332 and the surfaces of the second positioning section 332 for abutting against the first clamping portion 1051 have the same shape, so as to further increase the contact area between the first clamping portion 1051 and the second positioning section 332. For example, both are planar, increasing the mutual acting force along the first clamping portion 1051 and the second positioning section 332, making the abutment between the two more firm.

[0113] Optionally, as Figure 24 shown, the buckle 105 further includes a guiding portion 1052. The first clamping portion 1051 is connected to the guiding portion 1052 and arranged in sequence along the first direction. Along the first direction, the guiding portion 1052 is inclined away from the positioning projection 33.

[0114] Among them, the inclination direction of the first positioning section 331 is the same as that of the guiding portion 1052.

[0115] The guiding portion 1052 is connected to the first clamping portion 1051 and has a different inclination direction, so that a fold angle is formed at the connection between the guiding portion 1052 and the first clamping portion 1051.

[0116] The first positioning section 331 and the guiding portion 1052 have the same inclination direction. The first positioning section 331 and the guiding portion 1052 cooperate with each other, which is beneficial to the movement of the guiding portion 1052 along the first direction to the limiting position, making the guiding portion 1052 slide more smoothly and conveniently over the first positioning section 331 during the sliding process, playing a guiding role, so that the buckle 105 can smoothly reach the limiting position.

[0117] Optionally, the buckle 105 further includes a second clamping portion 1054. Along the first direction, the second clamping portion 1054 is arranged in sequence with the first clamping portion 1051 and the second clamping portion 1054 is inclined away from the positioning projection 33, so that a second bend 1055 is formed at the connection between the second clamping portion 1054 and the first clamping portion 1051, and the second bend 1055 corresponds to the first bend 208.

[0118] The second clamping portion 1054 is inclined in a direction away from the positioning protrusion 33, that is, the inclination direction of the second clamping portion 1054 is the same as the inclination direction of the first positioning section 331, and the second bending 1055 corresponds to the first bending 208, and the second clamping portion 1054 corresponds to the first positioning section 331. In this way, when the buckle 105 moves to the limit position, the first clamping portion 1051 abuts against the second positioning section 332, the second clamping portion 1054 abuts against the first positioning section 331, and the second bending 1055 corresponds to the first bending 208. In this way, the second clamping portion 1054 can limit the buckle 105 from continuing to move in the first direction after moving to the limit position.

[0119] Optionally, as Figure 24 shown, the side wall of the card slot 203 includes a first side wall 2031 and a second side wall 2032. The second side wall 2032 is disposed opposite to the first side wall 2031, and the first side wall 2031 and the second side wall 2032 are sequentially arranged in the first direction; wherein, at the limit position, the buckle 105 abuts against the second side wall 2032.

[0120] The card slot 203 is in a long strip shape. At one end of the card slot 203 close to the positioning portion 204 in the length direction of the card slot 203 is the second side wall 2032, and at the end far from the positioning portion 204 is the first side wall 2031. The first side wall 2031 and the second side wall 2032 are disposed opposite to each other, and the first side wall 2031 and the second side wall 2032 are sequentially arranged in the first direction. When the buckle 105 is inserted into the card slot 203, the first side wall 2031 and the second side wall 2032 are disposed on opposite sides of the buckle 105 in the length direction of the card slot 203.

[0121] When installing the wire pressing plate 10, the buckle 105 is inserted into the card slot 203. When the buckle 105 moves in the first direction along the length direction of the card slot 203, the buckle 105 approaches the second side wall 2032 of the card slot 203 away from the first side wall 2032 of the card slot 203. When the buckle 105 moves to the limit position, the buckle 105 abuts against the second side wall 2032 of the card slot 203, and the second side wall 2032 restricts the buckle 105 from continuing to move in the first direction at the limit position, thereby playing a role in limiting the buckle 105.

[0122] Optionally, as Figure 24 shown, an elastic groove 207 is provided at the connection between the positioning portion 204 and the chassis 20 or the wire pressing plate 10 where it is located.

[0123] When the positioning portion 204 is provided on the chassis 20, an elastic groove is provided at the connection between the positioning portion 204 and the chassis 20. When the positioning portion 204 is provided on the wire pressing plate 10, an elastic groove is provided at the connection between the positioning portion 204 and the wire pressing plate 10.

[0124] An elastic groove is provided at the connection between the positioning part 204 and the chassis 20 or the wire pressing plate 10 where it is located, which can enhance the elasticity and deformation ability of the limiting convex part, making it easier for the buckle 105 to move to the limiting position in the first direction, reducing the installation difficulty, and improving the installation efficiency of the wire pressing plate 10.

[0125] Taking the buckle 105 provided on the wire pressing plate 10 as an example, the buckle 105 can be bent from the material of the wire pressing plate 10 itself. An opening is provided at the connection between the buckle and the wire pressing plate to increase the elasticity of the buckle. The positioning part 204 can be formed by pressing the material on the chassis 20 or the wire pressing plate 10 where it is located.

[0126] Embodiment Three:

[0127] Based on Embodiment One, as Figures 8 to 16 shown, one of the chassis 20 and the wire pressing plate 10 is provided with a limiting protrusion 2044, and the other of the chassis 20 and the wire pressing plate 10 is provided with a limiting hole 205.

[0128] Among them, as Figure 13 and Figure 15 shown, the limiting hole 205 includes a first hole section 2051 and a second hole section 2052 that are connected. The opening size of the first hole section 2051 is larger than the opening size of the second hole section 2052. The limiting protrusion 2044 is limited in the second hole section 2052, and the opening size of the first hole section 2051 is larger than or equal to the size of the limiting protrusion 2044, so that the limiting protrusion 2044 can slide into the first hole section 2051 and can be disengaged from the first hole section 2051 under the action of an external force.

[0129] When the chassis 20 is provided with the limiting hole 205, the first connection and cooperation part 201 includes the limiting hole 205, and the first connection part 103 includes the limiting protrusion 2044 provided on the wire pressing plate 10. When the wire pressing plate 10 is provided with the limiting protrusion 2044, the first connection and cooperation part 201 includes the limiting hole 205 provided on the chassis 20, and the first connection part 103 includes the limiting protrusion 2044 provided on the wire pressing plate 10.

[0130] When one of the chassis 20 and the wire pressing plate 10 is provided with the limiting hole 205 and the other is provided with the limiting protrusion 2044, the positioning of the wire pressing plate 10 relative to the chassis 20 is realized through the cooperation of the limiting hole 205 and the limiting protrusion 2044.

[0131] When there are limit holes 205 provided on the chassis 10 and limit protrusions provided on the wire pressing plate 10, after the limit protrusion 2044 is inserted into the second hole section 5220, it is limited in the second hole section 2052. Through the cooperation between the limit protrusion 2044 and the second hole section 2052, the position of the wire pressing plate 10 relative to the chassis 20 can be restricted. When there are limit protrusions 2044 provided on the chassis 20 and limit holes 205 provided on the wire pressing plate 10, after the limit protrusion 2044 is inserted into the second hole section 2052, it is limited in the second hole section 2052. Through the cooperation between the limit protrusion 2044 and the second hole section 2052, the position of the wire pressing plate 10 relative to the chassis 20 can be restricted.

[0132] Through the cooperation between the limit protrusion 2044 and the second hole section 2052, the position of the wire pressing plate 10 relative to the chassis 20 can be restricted, realizing the positioning or fixing of the wire pressing plate 10 relative to the chassis 20. This positioning method is simple and easy to operate, does not require screwing, and has high production efficiency.

[0133] When disassembling the wire pressing plate 10, an external force is applied to the limit protrusion 2044. Under the action of the external force, the limit protrusion 2044 slides from the second hole section 2052 into the first hole section 2051. Since the opening size of the first hole section 2051 is greater than or equal to the size of the limit protrusion 2044, the limit protrusion 2044 can be disengaged from the first hole section 2051, thereby releasing the limit between the wire pressing plate 10 and the chassis 20 and realizing the disassembly of the wire pressing plate 10. And compared with the screw connection between the wire pressing plate 10 and the chassis 20, there is no problem of thread slipping due to multiple disassembly of the screws in this application. Thus, the wire pressing plate 10 can be disassembled repeatedly, improving production efficiency, reducing costs, and increasing the speed of after-sales maintenance.

[0134] Optionally, as Figure 13 shown, the opening size of the first hole section 2051 is greater than the opening size of the second hole section 2052.

[0135] The opening size of the second hole section 2052 is smaller than the size of the limit protrusion 2044, thereby realizing the limitation of the limit protrusion 2044. The opening size in the first hole section 2051 is greater than or equal to the size of the limit protrusion 2044, thereby realizing that the limit protrusion 2044 can be disengaged from the first hole section 2051.

[0136] The limiting protrusion 2044 has a three-dimensional structure and has multiple dimensions. The limiting protrusion 2044 has a dimension in the first direction. The second hole section 2052 limits the limiting protrusion 2044 by limiting the dimension in the first direction. Then, in the statement that "the opening dimension of the first hole section 2051 is larger than the opening dimension of the second hole section 2052", the opening dimension refers to the dimension in the first direction. The statement that "the opening dimension of the first hole section 2051 is larger than or equal to the dimension of the limiting protrusion 2044" means that "the dimension of the first hole section 2051 in the first direction is larger than or equal to the dimension of the limiting protrusion 2044 in the first direction".

[0137] For example, the dimension of the limiting protrusion 2044 in the first direction is the dimension in the length direction. When the limiting protrusion 2044 is located in the second hole section 2052, it is because the dimension of the limiting protrusion 2044 in the length direction is larger than the dimension of the second hole section 2052 in the length direction, resulting in the inability of the limiting protrusion 44 to escape from the second hole section 2052, that is, the second hole section 2052 limits the limiting protrusion 2044. Then, the length dimension of the first hole section 2051 is larger than the length dimension of the second hole section 2052, and the length dimension of the first hole section 2052 is larger than the length dimension of the limiting protrusion 2044.

[0138] Optionally, the limiting protrusion 2044 includes a first protrusion section 106 and a second protrusion section 107. The first protrusion section 106 is arranged inside the second hole section 2052; the second protrusion section 107 passes through the second hole section 2052 and is connected to the first protrusion section 106. The dimension of the second protrusion section 107 is larger than the opening dimension of the second hole section 2052 to prevent the second protrusion section 107 from escaping from the second hole section 2052, and the dimension of the second protrusion section 107 is smaller than or equal to the opening dimension of the first hole section 2051 so that the second protrusion section 107 can slide into the first hole section 2051 and escape from the first hole section 2051 under the action of an external force.

[0139] Along the direction in which the limiting protrusion 2044 is inserted into the second hole section 2052, the first protrusion section 106 and the second protrusion section 107 are arranged in sequence. When assembling the wire pressing plate 10 and the chassis 20, the limiting protrusion 2044 is inserted into the limiting hole 205, and the second protrusion section 107 passes through the first hole section 2051. At this time, the first protrusion section 106 is offset from the second hole section 2052. Since the wire pressing plate 10 itself has a certain elasticity, for example, the wire pressing plate 10 is a sheet metal part to meet the elasticity requirements of the wire pressing plate 10. Under the elastic action of the wire pressing plate 10, the first protrusion section 106 corresponds to the second hole section 2052, and the first protrusion section 106 is inserted into the second hole section 2052 to realize the limitation of the first protrusion section 106 by the second hole section 2052.

[0140] The opening size of the second protruding section 107 is less than or equal to the opening size of the first hole section 2051, so that the second protruding section 107 can smoothly pass through the first hole section 2051, realizing the detachment or insertion of the second protruding section 107 from the first hole section 2051. The opening size of the second hole section 2052 is less than the size of the second protruding section 107, and the second hole section 2052 can limit the second protruding section 107.

[0141] When disassembling the wire pressing plate 10, only an external force needs to be applied to the second protruding section 107. Under the action of the external force, the second protruding section 107 slides into the first hole section 2051 from the second hole section 2052, and the second protruding section 107 can easily detach from the first hole section 2051; and the wire pressing plate 10 can be disassembled repeatedly, reducing costs and improving production efficiency.

[0142] Optionally, the size of the first protruding section 106 is less than or equal to the opening size of the second hole section 2052, so that when the wire pressing plate 10 is assembled on the chassis 20, it is more convenient for the first protruding section 106 to be inserted into the second hole section 2052.

[0143] Both the first protruding section 106 and the second protruding section 107 are three-dimensional structures with multiple dimensions. The second protruding section 107 has a dimension in the first direction. The second hole section 2052 limits the second protruding section 107 by limiting the dimension in the first direction, preventing the second protruding section 107 from detaching from the second hole section 2052. Then, "the size of the second protruding section 107 is greater than the opening size of the second hole section 2052" means "the dimension of the second protruding section 107 in the first direction is greater than the opening dimension of the second hole section 107 in the first direction", "the size of the second protruding section 107 is less than or equal to the opening size of the first hole section 106" means "the dimension of the second protruding section 107 in the first direction is less than or equal to the opening dimension of the first hole section 5051 in the first direction", and "the size of the first protruding section 106 is less than or equal to the opening size of the second hole section 2052" means "the dimension of the first protruding section 106 in the first direction is less than or equal to the opening dimension of the second hole section 2052 in the first direction".

[0144] The dimension in the first direction is the dimension in the length direction ( Figure 10 the left-right direction in

[0145] Optionally, as Figure 10As shown, the second protruding section 107 includes a first limiting section 1071, a second limiting section 1072 and a third limiting section 1073. The second limiting section 1072 is arranged at one side of the first limiting section 1071; the third limiting section 1073 is connected to the first limiting section 1071 and arranged opposite to the second limiting section 1072; wherein, the orthographic projection of the first limiting section 1071 on the chassis 20 or the wire pressing plate 10 where the limiting hole 205 is located is located inside the second hole section 2052, and the orthographic projections of the second limiting section 1072 and the third limiting section 1073 on the chassis 10 or the wire pressing plate 10 where the limiting hole 205 is located are located outside the second hole section 2052.

[0146] The second protruding section 107 includes a first limiting section 1071, a second limiting section 1072, and a third limiting section 1073 sequentially arranged along the first direction. When the wire pressing plate 10 is assembled in place on the chassis 20, the first limiting section 1071 is arranged corresponding to the second hole section 2052, and the second limiting section 1072 and the third limiting section 1073 are staggered with the second hole section 2052, so that the second limiting section 1072 and the third limiting section 1073 cannot escape from the second hole section 2052, so that the second hole section 1052 can limit the second protruding section 107.

[0147] Alternatively, if Figure 13 As shown, the first hole section 2051 includes a second escape section 2054, a first escape section 2053 and a third escape section 2055 which are arranged in sequence. When the limiting protrusion 2044 enters the first hole section 2051, the first limiting section 1071 corresponds to the first escape section 2053, the second limiting section 1072 corresponds to the second escape section 2054, and the third limiting section 1073 corresponds to the third escape section 2055.

[0148] When installing the wire pressing plate 10, the second protruding section 107 passes through the first hole section 2051. Specifically, the first limiting section 1071 corresponds to the first escape section 2053, the second limiting section 1072 corresponds to the second escape section 2054, the first limiting section 1071 is inserted into the first escape section 2053, the second limiting section 1072 is inserted into the second escape section 2054, and the third limiting section 1073 is inserted into the third escape section 2055, so that the second protruding section 107 is inserted into the first hole section 2051; when the wire pressing plate 10 is disassembled, the limiting protrusion 2044 slides from the second hole section 2052 into the first hole section 2051 under the action of external force, so that the first limiting section 1071 is disengaged from the first disengaging section 2053, the second limiting section 1072 is disengaged from the second disengaging section 2054, and the third limiting section 1073 is disengaged from the third disengaging section 2055, so that the limiting protrusion 2044 can be disengaged from the limiting hole 205.

[0149] Alternatively, if Figure 10As shown, the limiting protrusion 2044 further includes a guiding protrusion section 108. The first protrusion section 106, the second protrusion section 107, and the guiding protrusion section 108 are arranged in sequence. The guiding protrusion section 108 is disposed on the side of the second protrusion section 2042 facing the first hole section 2051, and an obtuse angle is formed at the connection with the second protrusion section 107.

[0150] The guiding protrusion section 108 is connected to the second protrusion section 107 to form an obtuse angle. The guiding protrusion section 108 is disposed on the side of the second protrusion section 107 facing the first hole section 2051. The first hole section 2051 includes a first side 2056 and a second side 2057, and the first side 2056 and the second side 2057 are arranged in sequence along the direction from the first hole section 2051 to the second hole section 2052. In this way, when the wire pressing plate 10 is assembled, the guiding protrusion section 108 first slides into the first hole section 2051, and abuts against the second side 2057 during the sliding process, playing a guiding role, guiding the second protrusion section 107 to insert into the first hole section 2051, and driving the second protrusion section 107 to deform in the direction away from the second hole section 2052 during the guiding process. Thus, after the second protrusion section 107 enters and exits the first hole section 2051, the restoring force of the limiting protrusion 2044 due to deformation will guide the limiting protrusion 2044 to move towards the first hole section 2051, so that the first protrusion section 106 slides into the second hole section 2052.

[0151] Optionally, as Figure 11 shown, the wire pressing plate 10 or the chassis 20 provided with the limiting protrusion 2044 includes: a body 109, the body 109 is provided with a notch 112, and the limiting protrusion 2044 is connected to the side wall of the notch 112.

[0152] This can enhance the deformation ability of the limiting protrusion 2044. Thus, when the wire pressing plate 10 is installed, the second protrusion section 107 can pass through the first hole section 2051 and move towards the second hole section 2052 to abut against the second hole section 2052, fixing the wire pressing plate 10 to the chassis 20; when the wire pressing plate 10 is disassembled, under the action of an external force, the second protrusion section 107 can slide into the first hole section 2051 again, enabling the second protrusion section 107 to be disengaged from the first hole section 2051, and the wire pressing plate 10 can be disassembled.

[0153] Optionally, the chassis assembly of the air conditioner further includes an engaging portion 111 and an engaging and cooperating portion 206. The engaging portion 111 is disposed on one of the wire pressing plate 10 and the chassis 20; the engaging and cooperating portion 206 is disposed on the other of the wire pressing plate 10 and the chassis 20 and is engaged with the engaging portion 111.

[0154] The chassis 20 is provided with a clamping and mating portion 206, and the wire pressing plate 10 is provided with a clamping portion 111, or the chassis 20 is provided with a clamping portion 111, and the wire pressing plate 10 is provided with a clamping and mating portion 206. One of the clamping portion 111 and the clamping and mating portion 206 is a snap, and the other is a slot. The snap is snap-fitted with the slot, which can limit the wire pressing plate 10 to prevent the wire pressing plate 10 from shifting or being misaligned during installation, making the connection between the wire pressing plate 10 and the chassis 20 more stable, and also enhancing the connection strength between the wire pressing plate 10 and the chassis 20.

[0155] Wherein, one or more clamping portions 111 and clamping and mating portions 206 may be provided, and the number of the clamping portions 111 and the clamping and mating portions 206 is equal and they correspond to each other one by one.

[0156] The limiting protrusion 2044 and the clamping portion 111 are provided on opposite sides in the width direction of the wire routing groove 31.

[0157] Optionally, along the direction in which the clamping portion 111 and the clamping and mating portion 206 are snap-fitted, the second hole section 2052 and the first hole section 2051 are arranged in sequence.

[0158] When removing the wire pressing plate 10, an external force is applied to the second protruding section 107, so that the second protruding section 107 slides into and out of the first hole section 2051. The direction of the external force is the direction in which the clamping portion 111 and the clamping and mating portion 206 are snap-fitted, that is, the direction in which the connection between the two is more secure, avoiding the separation of the clamping portion 111 and the clamping and mating portion 206 due to the external force.

[0159] It can be understood that in the second embodiment, the chassis assembly may also include a clamping portion 111 and a clamping and mating portion 206. The clamping portion 111 is provided on one of the wire pressing plate 10 and the chassis 20; the clamping and mating portion 206 is provided on the other of the wire pressing plate 10 and the chassis 20 and is snap-fitted with the clamping portion 111.
