[0040] In the related art, the internal wiring of the air conditioner is located on the upper side of the air outlet, which allows the back side of the chassis to have a larger wiring space for arranging refrigerant pipes, condensate pipes and other pipes, ensuring the reliable installation of the pipes. However, the upper side of the air outlet is the junction between the chassis body and the front of the face frame, which is not conducive to the safe use of the wires.

[0041] In order to solve this technical problem, the utility model proposes a chassis assembly.

[0042] See also Figures 1 to 6In one embodiment of the present utility model, the chassis assembly includes a chassis 10 and a limiting pressure piece 20, and a wiring structure is provided at the lower end of the back side of the chassis 10; the limiting pressure piece 20 is provided on the back side of the chassis 10, and is enclosed with the chassis 10 to form a wiring space 101 for the pipeline 40 to pass through, one end of the limiting pressure piece 20 is rotatably connected to the chassis 10, and the other end spans above the wiring structure and is detachably connected to the chassis 10, at least part of the limiting pressure piece 20 is protruding downward to avoid the pipeline 40; so as to improve the installation reliability of the pipeline 40.

[0043] In the technical solution of the present invention, a limiting pressure piece 20 is used to fix the pipeline 40 on the back of the chassis 10, wherein one end of the limiting pressure piece 20 is rotatably connected to the chassis 10, and the other end of the limiting pressure piece 20 is detachably connected to the chassis 10, which facilitates the installation and maintenance of the pipeline 40. In addition, since at least part of the limiting pressure piece 20 is protruding downward, the pipe running space 101 can be increased to a certain extent. Furthermore, on the basis of protecting the wire body 50 through the routing structure, the influence of the routing structure on the pipe running space 101 is reduced. At the same time, the risk of the pipeline 40 pushing out the limiting pressure piece 20 due to insufficient routing space 101 and the failure of the limiting pressure piece 20 is reduced, thereby improving the installation reliability of the pipeline 40, and reducing the risk of the limiting pressure piece 20 squeezing the pipeline 40 and affecting the conveying effect of the pipeline 40, thereby improving the safety of use of the pipeline 40.

[0044] It should be noted that the chassis assembly can be applied to an air conditioner, specifically an indoor unit of the air conditioner. In this case, the indoor unit can be configured as a wall-mounted indoor unit or other types of indoor units; wherein, the back of the chassis 10 has a first side wall 102 and a second side wall 103 set at an angle, the first side wall 102 is located above the second side wall 103, and the lower end of the second side wall 103 is provided with the wiring structure, one end of the limiting pressure piece 20 is rotatably connected to the first side wall 102, and the other end is detachably connected to the second side wall 103 to form the wiring space 101, which can make the wiring space 101 large enough to ensure the assembly of the pipeline 40; of course, in other embodiments, the back of the chassis 10 has a first side wall 102, and the lower end of the first side wall 102 is provided with a wiring structure, one end of the limiting pressure piece 20 is connected to the upper end of the first side wall 102, and the other end is connected to the first side wall 102, and is located above the wiring structure.

[0045] The pipeline 40 includes at least an input pipe, an output pipe and an insulation pipe 41. The input pipe and the output pipe are used to transport the refrigerant, and both can be made of metal pipes such as copper pipes. The insulation pipe 41 wraps the input pipe and the output pipe to maintain the temperature of the refrigerant during the transportation process. At the same time, it can also separate the input pipe and the output pipe to avoid mutual influence between the temperatures of the two.

[0046] Specifically, when the other end of the limiting pressure piece 20 is connected to the chassis 10, the limiting pressure piece 20 is in a limiting state, and a pipe running space 101 is formed, completing the limitation of the pipe 40; the detachable connection between the limiting pressure piece 20 and the chassis 10 includes but is not limited to a snap connection and a latch fixation; when the other end of the limiting pressure piece 20 is separated from the chassis 10, the other end of the limiting pressure piece 20 can be rotated in a direction away from the chassis 10 and is in an open state, which is convenient for installing and maintaining the pipe 40 in the pipe running space 101 and other structures on the back of the chassis 10; wherein, the other end of the limiting pressure piece 20 is located above the wiring structure, which is conducive to avoiding the wiring structure, reducing the influence of the wiring structure on the pipe running space 101, and can make The wire body 50 is in a relatively independent space, avoiding contact between the wire body 50 and other components, thereby ensuring the electrical safety of the air conditioner. At the same time, since at least part of the limiting pressure piece 20 is protruding downward, that is, away from the pipeline 40, compared with the limiting pressure piece 20 being located above the wiring structure as a whole, at least part of the limiting pressure piece 20 is lower than the upper surface of the wiring structure, thereby increasing the wiring space 101 and effectively avoiding the pipeline 40 and the wiring structure, reducing the risk of the pipeline 40 pushing out the limiting pressure piece 20 due to insufficient wiring space 101 and causing the limiting pressure piece 20 to fail, thereby improving the installation reliability of the pipeline 40, and reducing the risk of the limiting pressure piece 20 squeezing the pipeline 40 and affecting the transportation effect of the pipeline 40, thereby improving the safety of the use of the pipeline 40.

[0047] like Figure 2 As shown, in this embodiment, the wiring structure is configured as a wiring trough 12 with a downward opening. The wiring trough 12 is used to guide the wires 50, thereby reliably concentrating and protecting the wires 50. The wires 50 can specifically guide power cables, signal cables, and the like. Of course, in other embodiments, the opening of the wiring trough 12 is configured to face upward; or the wiring structure is configured as a wire buckle and / or wiring trough 12. In addition, the wiring structure can be integrally provided with the lower end of the second side wall 103, and the wiring structure and the second side wall 103 can be fixed into a whole by, for example, integral molding, welding, etc.; or they can be provided separately.

[0048] See also Figure 2 In an embodiment of the present utility model, the limiting pressure piece 20 includes a rotating arm 21 and a support arm 22 that are bent and connected to each other. The end of the rotating arm 21 away from the support arm 22 is rotatably connected to the chassis 10, and the end of the support arm 22 away from the rotating arm 21 is detachably connected to the chassis 10. At least part of the support arm 22 is configured to protrude downward. It can be understood that compared with the horizontally extending straight structure of the support arm 22, the support arm 22 is a folded structure, that is, the contour line of the support arm 22 is a zigzag multi-segment line, which can enhance the strength of the support arm 22 to a certain extent, thereby improving the limiting effect of the limiting pressure piece 20 on the pipeline 40 and the service life of the limiting pressure piece 20.

[0049] When the limiting pressure piece 20 is in the limiting state, the rotating arm 21 is a straight structure and extends along the up and down directions of the air conditioner. This can effectively prevent the limiting pressure piece 20 from protruding from the back of the air conditioner, which is beneficial to simplify the structure of the installation back plate 30 of the air conditioner, and then the installation back plate 30 of the air conditioner can be made to fit the wall and reduce the assembly gap between the air conditioner and the wall.

[0050] Specifically, in an embodiment of the present utility model, the support arm 22 includes at least a first connecting section 221 and a supporting section 222. The first connecting section 221 is located above the wiring structure and is connected to the chassis 10. One end of the support section 222 is connected to the first connecting section 221, and the other end extends downward at an angle and is used to connect to the rotating arm 21, so that the space sandwiched between the rotating arm 21 and the support section 222 forms a part of the wiring space 101. Compared with the support section 222 being vertically connected to the rotating arm 21, the wiring space 101 is effectively increased, ensuring reliable limitation of the pipeline 40, and also helping to improve the structural strength of the support arm 22 and improve the supporting effect of the support arm 22 on the pipeline 40.

[0051] More specifically, in an embodiment of the present invention, the support arm 22 also includes a second connecting segment 223, one end of the second connecting segment 223 is connected to the rotating arm 21, and the other end is connected to the support segment 222; at this time, the second connecting segment 223 is perpendicular to the rotating arm 21, or the angle between the second connecting segment 223 and the rotating arm 21 is less than 90°, that is, the second connecting segment 223 extends in the extension direction of the support segment 222 and is inclined downward. Of course, the inclination angle of the second connecting segment 223 can also be smaller than the inclination angle of the support segment 222, which helps to improve the structural strength of the support arm 22.

[0052] Optionally, in an embodiment of the present utility model, the first connecting section 221 is tilted downward in the direction toward the rotating arm 21, and its tilt angle is smaller than the tilt angle of the supporting section 222, that is, on the basis of ensuring the avoidance effect of the first connecting section 221 on the routing structure and the connection between the first connecting section 221 and the chassis 10, the routing space 101 can be increased by the tilting setting of the first connecting section 221, and, by making the tilt angle of the first connecting section 221 smaller than the tilt angle of the supporting section 222, the first connecting section 221 can be made as close to the routing structure as possible until it is adapted to the upper surface of the routing structure, so that the routing structure can support and limit the first connecting section 221, thereby improving the service life of the limiting pressure piece 20.

[0053] See also Figures 2 to 6In an embodiment of the present invention, a latching protrusion 23 is provided on the end of the first connecting section 221 away from the support section 222, and a latching hole 11 is provided on the chassis 10 for the latching protrusion 23 to engage. It is understood that by rotating the limiting pressure member 20, the latching protrusion 23 is brought closer to the latching hole 11 on the second side wall 103. During this process, the latching protrusion 23 crosses the routing structure and passes through the latching hole 11, becoming latched at the lower edge of the latching hole 11, thereby achieving a fixed connection between the limiting pressure member 20 and the chassis 10. Furthermore, because the latching protrusion 23 has an auxiliary inclined surface on the side facing away from the rotating arm 21, this auxiliary inclined surface can assist in the deformation of the support arm 22, thereby accelerating the latching efficiency. However, in other embodiments, the end of the support section 222 away from the rotating arm 21 is provided with a latching hole 11, and the second side wall 103 is provided with a fastener that cooperates with the latching hole 11; or, the first connecting section 221 is latched to the edge of the latching hole 11 by a latch.

[0054] Optionally, in an embodiment of the present invention, a support reinforcement rib 25 is provided on the side of the position-limiting pressure piece 20 facing away from the pipeline 40 to enhance the overall structural strength of the position-limiting pressure piece 20 while not occupying the pipe routing space 101. Furthermore, when the support reinforcement rib 25 is disposed near the buckle protrusion 23, the support reinforcement rib 25, the buckle protrusion 23, and the first connecting segment 221 can form a buckle groove. In this case, the buckle protrusion 23 restricts the first connecting segment 221 from disengaging from the buckle hole 11, and the support reinforcement rib 25 abuts against the inner side of the edge of the buckle hole 11, thereby restricting further rotation of the position-limiting pressure piece 20.

[0055] Furthermore, support reinforcement ribs 25 are provided on opposite sides of the position-limiting pressure member 20 in the left-right direction. The left-right direction is the longitudinal direction of the air conditioner. The support reinforcement ribs 25 connect the rotating arm 21 and the support arm 22 to improve the connection strength between the rotating arm 21 and the support arm 22.

[0056] See also Figure 2 、 Figures 7 to 10In an embodiment of the present utility model, the position-limiting pressure piece 20 further includes a supporting protrusion 24, which is connected to the rotating arm 21 and protrudes from the side of the supporting arm 22 away from the pipe 40. The supporting protrusion 24 is used to engage with the opening 31 on the mounting back plate 30 of the air conditioner, so that the position-limiting pressure piece 20 supports the air conditioner; it can be understood that the supporting protrusion 24 is connected to the lower end of the rotating arm 21, which is the end away from the first side wall 102. The supporting protrusion 24 can also be connected to the side of the supporting arm 22 away from the first side wall 102. More specifically, the supporting protrusion 24 The protrusion 24 is connected to the side of the connection between the rotating arm 21 and the support arm 22 away from the pipeline 40 to ensure the protruding setting of the support protrusion 24. Then, when disassembling or maintaining the pipeline 40, the support protrusion 24 is engaged with the opening 31 on the mounting back plate 30 to maintain the lower end of the air conditioner stably lifted. In this way, space can be freed up for connecting and removing pipes, thereby improving the convenience of disassembling and installing the pipeline 40. In addition, during the process of disassembling and installing the pipeline 40, manpower or additional special tools are no longer required to maintain the lower end of the air conditioner lifted. Only one person can complete the disassembly and maintenance of the pipeline 40, effectively reducing costs.

[0057] The cam 24 is then released from the locking cam 24 and the locking cam 24 is engaged with the locking cam 24. The locking cam 24 is engaged with the locking cam 24 and the locking cam 24. The locking cam 24 is engaged with the locking cam 24.

[0058] See also Figures 3 to 6 In the embodiment of the present invention, a connecting seat is protruded from the chassis 10, and the rotating arm 21 is hingedly connected to the connecting seat to realize the rotational movement of the limiting pressure member 20 relative to the chassis 10, thereby meeting the requirements of limiting the position of the pipeline 40 and maintaining the pipeline 40. Of course, other structures that can realize the rotation of the limiting pressure member 20 can also be used in the present invention.

[0059] Specifically, in an embodiment of the present invention, the connection base includes two connection ears 13 disposed on opposite sides of the rotating arm 21. The connection ears 13 are provided with hinge holes 131. The side of the rotating arm 21 facing the connection ears 13 is provided with a rotating shaft 26 that is inserted into the hinge holes 131. Furthermore, an operator can grasp and apply force to the limiting pressure piece 20. The limiting pressure piece 20 is inserted into the hinge holes 131 via the rotating shaft 26 and rotates around the axis of the hinge holes 131 as force is continued. The hinge holes 131 can penetrate the connection ears 13 or be blind holes; and the connection base formed by the two connection ears 13 can be a single piece.

[0060] like Figure 4 and Figure 6 As shown, in an embodiment of the present utility model, the hinge hole 131 is provided with a mounting notch 132 near one end of the rotating arm 21, and the surface of the mounting notch 132 facing the rotating arm 21 is configured as a guide slope 133, and the rotating shaft 26 is provided with a guide matching surface 261 matching the guide slope 133. In this way, through the setting of the mounting notch 132 and the guide slope 133, the rotating shaft 26 is conveniently slid into the hinge hole 131 quickly, completing the assembly of one end of the limiting pressure piece 20; specifically, the assembly steps of one end of the limiting pressure piece 20 are: align the rotating shaft 26 with the mounting notch 132, and align the guide slope 133 and the guide matching surface 261, and then, in the process of moving the rotating shaft 26 toward the mounting notch 132, through the guiding action of the guide slope 133, the guide matching surface 261 of the rotating shaft 26 is attached to the guide slope 133, and slides into the hinge hole 131 along the guide slope 133.

[0061] The present utility model also proposes an air conditioner, which includes a chassis assembly. The specific structure of the chassis assembly refers to the above-mentioned embodiment.
