[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0043] An air conditioner 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0044] like Figure 1 and Figure 2 As shown, an air conditioner 100 according to an embodiment of the present invention includes: a housing assembly 1 and a heat exchanger 2. The heat exchanger 2 is disposed within the housing assembly 1 and includes a heat exchanger body 21 and a connecting pipe 22 disposed within the heat exchanger body 21. The connecting pipe 22 and the heat exchanger body 21 are arranged along a first direction. Multiple refrigerant channels are formed within the heat exchanger body 21. Two adjacent refrigerant channels are connected through the connecting pipe 22. The housing assembly 1 includes a first sidewall 11. The first sidewall 11 and a portion of the connecting pipe 22 are arranged opposite to each other along the first direction and spaced apart. A clearance groove 111 is formed on the side of the first sidewall 11 facing the connecting pipe 22. The connecting pipe 22 is spaced apart from the inner wall surface of the clearance groove 111.

[0045] In other words, the connecting pipe 22 is connected to the end of the heat exchanger body 21 in the first direction, and the clearance groove 111 is formed on the part of the first side wall 11 opposite to the connecting pipe 22 in the first direction. Since the clearance groove 111 is recessed into the side of the first side wall 11 opposite to the connecting pipe 22, that is, the clearance groove 111 is recessed in the direction away from the connecting pipe 22 in the first direction, the distance between the inner bottom wall of the first side wall 11 and the connecting pipe 22 can be increased in the first direction, thereby providing sufficient clearance space for the connecting pipe 22 in the first direction. Therefore, when the air conditioner 100 is dropped during transportation, the clearance groove 111 can prevent the connecting pipe 22 from collide with the first side wall 11 and be damaged, thereby avoiding the risk of leakage caused by the collision deformation of the connecting pipe 22, and improving the safety of transporting the air conditioner 100.

[0046] According to the embodiment of the air conditioner 100 of the present invention, when the air conditioner 100 is dropped during transportation, the avoidance groove 111 can prevent the connecting pipe 22 from moving with the heat exchanger 2 and colliding with the first side wall 11 to cause damage, thereby avoiding the risk of leakage due to collision deformation of the connecting pipe 22, and improving the safety of transporting the air conditioner 100.

[0047] According to some embodiments of the present invention, in the first direction, the inner wall surface of the clearance groove 111 opposite to the connecting pipe 22 is the first clearance surface, and the distance between the connecting pipe 22 and the first clearance surface is not less than 10 mm. It can be understood that the greater the distance between the first clearance surface and the connecting pipe 22 in the first direction, the larger the space reserved for the movement of the connecting pipe 22 in the first direction; in other words, the lower the probability of the connecting pipe 22 contacting the first clearance surface. Therefore, by controlling the distance between the connecting pipe 22 and the first clearance surface in the first direction to not less than 10 mm, sufficient clearance space is ensured between the connecting pipe 22 and the first clearance surface to prevent the risk of leakage due to collision and deformation of the connecting pipe 22 and the first clearance surface, thereby improving the safety of transporting the air conditioner 100. For example, the distance between the connecting pipe 22 and the first clearance surface in the first direction can be 10 mm, 10.5 mm, 11 mm, 11.5 mm, 12 mm, 12.5 mm, 13 mm, etc.

[0048] According to some embodiments of the present invention, the connecting pipe 22 is an arc-shaped pipe, and the inner wall surface of the clearance groove 111 is arc-shaped. This allows the inner wall surface of the clearance groove 111 to better match the shape of the connecting pipe 22, thereby enabling more precise control of the distance between the connecting pipe 22 and the inner wall surface of the clearance groove 111. This ensures that the distance between the side of the connecting pipe 22 facing the first sidewall 11 in the first direction and the inner wall surface of the clearance groove 111 is controlled at a safe distance (e.g., 10 mm) or more, thus guaranteeing the clearance effect of the clearance groove 111.

[0049] According to some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the first sidewall 11 protrudes in a first direction away from the heat exchanger 2 to form a bulge 112, and a clearance groove 111 is formed within the bulge 112. That is, the portion of the first sidewall 11 opposite to the connecting pipe 22 in the first direction protrudes in a direction away from the heat exchanger 2 to form the bulge 112. With the formation of the bulge 112, a clearance groove 111 is formed on the side of the first sidewall 11 facing the connecting pipe 22. Therefore, in the production design of the housing assembly 1, only the structure corresponding to the bulge 112 needs to be added to the mold of the first sidewall 11 portion. That is, while ensuring that the wall thickness of the first sidewall 11 remains unchanged, a clearance groove 111 is formed on the side of the first sidewall 11 facing the connecting pipe 22, which can reduce the material cost required to form the clearance groove 111.

[0050] According to some embodiments of the present invention, such as Figures 3 to 6 As shown, the air conditioner 100 also includes a refrigerant inlet / outlet pipe 3, and the housing assembly 1 also includes a second sidewall 12 that is opposite to and spaced apart from the first sidewall 11. In a first direction, the second sidewall 12 is located on the side of the first sidewall 11 away from the heat exchanger 2 and together with the first sidewall 11 defines a pipe space 13. The refrigerant inlet / outlet pipe 3 is connected to the heat exchanger 2 and runs along the pipe space 13. The side of the second sidewall 12 facing the first sidewall 11 is the first sidewall 121. An avoidance structure opposite to the protrusion 112 is formed on the first sidewall 121. The side of the avoidance structure facing the first sidewall 11 is the second avoidance surface 122. The distance between the second avoidance surface 122 and the protrusion 112 is greater than the distance between the first sidewall 121 and the protrusion 112.

[0051] One end of the refrigerant inlet / outlet pipe 3 is located inside the housing assembly 1 and connected to the heat exchanger 2. The other end of the refrigerant inlet / outlet pipe 3 extends to the outside of the housing assembly 1 through the pipe space 13 to connect with other components such as the compressor. Through its connection with the heat exchanger 2, the refrigerant inlet / outlet pipe 3 supplies refrigerant into the heat exchanger 2 and discharges refrigerant from the heat exchanger 2, thereby achieving continuous circulation of the refrigerant within the heat exchanger 2. In other words, the portion of the first sidewall 11 opposite to the connecting pipe 22 in the first direction extends towards the second sidewall 12 to form a protrusion 112, which occupies part of the space within the pipe space 13. Therefore, by providing a clearance structure on the first sidewall 121, clearance space can be provided for the portion of the refrigerant inlet / outlet pipe 3 that runs along the pipe space 13, thereby preventing the protrusion 112 from lifting the refrigerant inlet / outlet pipe 3 and affecting its routing.

[0052] In a specific example, the first direction is the left-right direction. A connecting sidewall is also formed on the housing assembly 1. The connecting sidewall extends in the left-right direction and is located between the first sidewall 11 and the second sidewall 12. The connecting sidewall is located at the bottom of the pipe space 13. The left and right ends of the connecting sidewall are connected to the first sidewall 11 and the second sidewall 12, respectively. The first sidewall 11, the second sidewall 12 and the connecting sidewall together define the pipe space 13. At the same time, the first sidewall 11, the second sidewall 12 and the connecting sidewall can effectively enhance the structural strength at the location of the pipe space 13 to prevent structural deformation around the pipe space 13.

[0053] According to some embodiments of the present invention, in the first direction, the distance between the second clearance surface 122 and the first side surface 121 is greater than the height of the protrusion of the bulge 112. That is, in the first direction, the clearance space provided by the clearance structure for the refrigerant inlet / outlet pipe 3 is greater than the space occupied by the bulge 112 in the pipe running space 13. Therefore, the clearance structure can better ensure its effect of clearing the refrigerant inlet / outlet pipe 3, preventing the refrigerant inlet / outlet pipe 3 from contacting and being squeezed by the second side wall 12.

[0054] According to some embodiments of the present invention, in the first direction, the distance between the second clearance surface 122 and the first side surface 121 ranges from 4mm to 8mm. That is, the clearance space provided by the clearance structure for the refrigerant inlet / outlet pipe 3 in the first direction is controlled within the range of 4mm to 8mm. It can be understood that the greater the distance between the second clearance surface 122 and the first side surface 121 in the first direction, the more clearance space can be provided for the refrigerant inlet / outlet pipe 3 in the first direction. However, the larger the space occupied by the clearance structure in the first direction, the more clearance space is detrimental to the overall structural strength of the housing assembly 1. Conversely, the closer the distance between the second clearance surface 122 and the first side surface 121 in the first direction, the less space the clearance structure occupies in the first direction, and the smaller the impact of the clearance structure on the overall structural strength of the housing assembly 1. However, the smaller the clearance space provided for the refrigerant inlet / outlet pipe 3 in the first direction. Therefore, by controlling the distance between the second clearance surface 122 and the first side surface 121 in the first direction to be between 4mm and 8mm, it is possible to ensure that the clearance structure provides sufficient clearance space for the refrigerant inlet and outlet pipes 3 while reducing the impact on the overall structural strength of the housing assembly 1. For example, the distance between the second clearance surface 122 and the first side surface 121 in the first direction can be 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, etc.

[0055] According to some embodiments of the present invention, the second clearance surface 122 has a dimension of 20mm to 30mm in the second direction, and the second direction is perpendicular to the first direction. It is understood that a larger dimension of the second clearance surface 122 in the second direction provides more clearance space for the refrigerant inlet / outlet pipe 3 in the second direction, but a larger space occupied by the clearance structure in the second direction is detrimental to the overall structural strength of the housing assembly 1. Conversely, a smaller dimension of the second clearance surface 122 in the second direction occupies less space in the second direction, resulting in a smaller impact on the overall structural strength of the housing assembly 1, but provides less clearance space for the refrigerant inlet / outlet pipe 3 in the first direction. Therefore, by controlling the dimension of the second clearance surface 122 in the second direction to 20mm to 30mm, it is possible to ensure that the clearance structure provides sufficient clearance space for the refrigerant inlet / outlet pipe 3 while reducing the impact on the overall structural strength of the housing assembly 1. For example, the dimensions of the second clearance surface 122 in the second direction can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, etc.

[0056] According to some embodiments of the present invention, the pipe routing space 13 extends to the back side of the housing assembly 1, and the second clearance surface 122 extends to the back side of the housing assembly 1. That is, the refrigerant inlet / outlet pipe 3 can run through the pipe routing space 13 to the back side of the housing assembly 1 to run along the back side of the housing assembly 1. The second clearance surface 122 extends to the back side of the housing assembly 1 together with the pipe routing space 13, thereby ensuring that during the process of the refrigerant inlet / outlet pipe 3 being led out of the housing assembly 1 along the pipe routing space 13, the clearance structure can provide a clearance effect for the refrigerant inlet / outlet pipe 3 to prevent the refrigerant inlet / outlet pipe 3 from contacting the second side wall 12.

[0057] In a specific example, the air conditioner 100 is a wall-mounted air conditioner. The casing assembly 1 includes a chassis, and the heat exchanger 2 is mounted on the chassis. The first direction is left-right, the second direction is front-back, and the third direction is front-back. The pipe space 13 extends vertically and rearward to the back of the chassis, allowing the refrigerant inlet and outlet pipes 3 to extend through the pipe space 13 to the back of the chassis and run along the back of the chassis. The first side surface 121 is located in front of the second clearance surface 122. A stepped surface 123 is formed between the second clearance surface 122 and the first side surface 121. The width of the stepped surface 123 in the left-right direction is 6mm. The rear end of the second clearance surface 122 extends to the back of the chassis, and the width of the second clearance surface 122 in the front-back direction is 25mm. Therefore, the molding difficulty of the clearance structure can be reduced; that is, the clearance structure can be formed by setting a stepped structure on the mold, while ensuring that the clearance structure can provide sufficient pipe space 13 for the refrigerant inlet and outlet pipes 3. In addition, a reinforcing rib can be provided on the second clearance surface 122. The reinforcing rib extends in the front-back direction and is connected to the step surface 123. Thus, the reinforcing rib can better compensate for the impact of the clearance structure on the structural strength of the second side wall 12.

[0058] According to some embodiments of the present invention, such as Figure 7 and Figure 8 The heat exchanger 2 is provided with a limiting engagement part 23, and a limiting baffle 14 is provided on the inner wall surface of the housing assembly 1. At least a portion of the limiting baffle 14 is located in the first direction of the limiting engagement part 23 and is disposed opposite to the limiting engagement part 23. Therefore, by using the portion of the limiting baffle 14 opposite to the limiting engagement part 23 in the first direction, the movement of the limiting engagement part 23 in the first direction can be effectively blocked. Thus, by limiting the limiting engagement part 23, the axial movement of the heat exchanger 2 in the first direction can be restricted. Therefore, when the air conditioner 100 is dropped during transportation, the axial movement of the heat exchanger 2 in the first direction can be reduced by the cooperation of the limiting baffle 14 and the limiting engagement part 23. This reduces the displacement distance of the connecting pipe 22 toward the first side wall 11 by controlling the axial movement distance of the heat exchanger 2, thereby preventing the connecting pipe 22 from colliding and deforming with the first side wall 11 and causing leakage, which helps to improve the transportation safety of the air conditioner 100.

[0059] According to some embodiments of the present invention, the limiting baffle 14 is located on the side of the limiting mating part 23 facing the first sidewall 11 in the first direction. That is, in the first direction, the limiting baffle 14 is located between the limiting mating part 23 and the first sidewall 11. Therefore, the limiting baffle 14 can effectively block the movement of the limiting mating part 23 toward the first sidewall 11, thereby reducing the amplitude of the heat exchanger 2's movement toward the first sidewall 11. This can reduce the displacement of the connecting pipe 22 toward the first sidewall 11 when the air conditioner 100 is dropped, thus preventing the connecting pipe 22 from colliding and deforming with the first sidewall 11 and causing leakage, which helps to improve the transportation safety of the air conditioner 100.

[0060] According to some embodiments of the present invention, the sides of the limiting baffle 14 and the limiting mating part 23 opposite to each other along the first direction are the limiting surfaces, and the limiting surfaces and the limiting mating part 23 are spaced apart. That is, the limiting surfaces and the limiting baffle 14 do not contact each other. Thus, while ensuring the limiting effect of the limiting surface on the limiting mating part 23, the increased installation difficulty caused by contact friction between the limiting baffle 14 and the limiting mating part 23 can be avoided, thereby improving the installation efficiency of the heat exchanger 2.

[0061] According to some embodiments of the present invention, the distance between the limiting mating part 23 and the limiting surface in the first direction ranges from 2mm to 8mm. The greater the distance between the limiting mating part 23 and the limiting surface in the first direction, the lower the probability of the limiting mating part 23 contacting the limiting surface during heat exchanger 2 installation, but the worse the limiting effect of the limiting surface on the limiting mating part 23 in the first direction. Conversely, the greater the distance between the limiting mating part 23 and the limiting surface in the first direction, the better the limiting effect of the limiting surface on the limiting mating part 23 in the first direction, but the higher the probability of the limiting mating part 23 contacting the limiting surface during heat exchanger 2 installation. Therefore, by controlling the distance between the limiting mating part 23 and the limiting surface in the first direction within the range of 2mm to 8mm, the limiting effect of the limiting baffle 14 on the limiting mating part 23 can be ensured while avoiding contact between the limiting mating part 23 and the limiting baffle 14, which would affect installation efficiency. For example, the distance between the limiting mating part 23 and the limiting surface in the first direction can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc.

[0062] According to some embodiments of the present invention, the heat exchanger 2 further includes a side plate 24 disposed at the upper end of the heat exchanger body 21 in a first direction, and a connecting ear 25 disposed at one end of the side plate 24 in a second direction. The connecting ear 25 is connected to the inner wall surface of the housing assembly 1 in a third direction, and a limiting fit portion 23 is disposed on the connecting ear 25. That is, the limiting baffle 14 can effectively restrict the degree of freedom of movement of the connecting ear 25 in the first direction, thereby reducing the deformation range of the side plate 24 when the air conditioner 100 falls. In addition, by disposing of the limiting fit portion 23 on the connecting ear 25, the connecting ear 25 can be used as a limiting fit structure that cooperates with the limiting baffle 14, eliminating the need for an additional limiting fit structure that cooperates with the limiting baffle 14, thereby simplifying the structure of the heat exchanger 2.

[0063] According to some embodiments of the present invention, the limiting mating part 23 and the limiting baffle 14 are located on the outer periphery of the heat exchanger body 21. That is, the mating position of the limiting mating part 23 and the limiting baffle 14 is located on the outer periphery of the heat exchanger body 21, where the outer periphery of the heat exchanger body 21 refers to the outer peripheral region of the heat exchanger body 21 in the direction perpendicular to the first direction. This avoids the heat exchanger body 21 obstructing the limiting mating part 23 and the limiting baffle 14, allowing for a more direct and clear observation of the limiting mating part 23 and the limiting baffle 14, thereby reducing the difficulty of mating the limiting mating part 23 and the limiting baffle 14 and improving the installation efficiency of the heat exchanger 2.

[0064] According to some embodiments of the present invention, the housing assembly 1 further includes a third sidewall 16 and a fourth sidewall 17 connected and arranged at an included angle. The third sidewall 16 and the fourth sidewall 17 are located on the outer periphery of the heat exchanger body 21. A limiting baffle 14 is disposed at the included angle of the third sidewall 16 and the fourth sidewall 17 and is connected to both the third sidewall 16 and the fourth sidewall 17. Therefore, the connection strength between the limiting baffle 14 and the housing assembly 1 can be improved, thereby ensuring the positional stability of the limiting baffle 14 and improving the limiting effect of the limiting baffle 14 on the limiting mating part 23.

[0065] According to some embodiments of the present invention, the limiting baffle 14 includes a limiting plate 141, a first reinforcing plate 142 and a second reinforcing plate 143. The limiting plate 141 and the limiting mating part 23 are disposed opposite to each other along a first direction. The first reinforcing plate 142 is disposed at an angle to the limiting plate 141 and the second reinforcing plate 143. The limiting plate 141 and the second reinforcing plate 143 are connected to opposite ends of the first reinforcing plate 142 in the first direction and extend in opposite directions along a second direction, which is perpendicular to the first direction. The limiting surface is formed on the side of the limiting plate 141 facing the limiting mating part 23. That is, the first reinforcing plate 142 is supported on the side of the limiting plate 141 away from the limiting mating part 23 in the first direction, and the second reinforcing plate 143 is supported on the side of the first reinforcing plate 142 away from the limiting plate 141. The limiting plate 141 and the second reinforcing plate 143 are arranged in a roughly parallel manner, and the first reinforcing plate 142 is arranged in a roughly perpendicular manner to the limiting plate 141 and the second reinforcing plate 143. The limiting plate 141, the first reinforcing plate 142 and the second reinforcing plate 143 roughly form a "Z" shaped fold structure, which can better improve the structural strength of the limiting baffle 14, so as to improve the limiting effect of the limiting baffle 14 on the limiting mating part 23.

[0066] According to some embodiments of the present invention, such as Figures 9-11 As shown, a reinforcing structure 15 is also provided on the inner wall surface of the housing assembly 1, and the reinforcing structure 15 is connected to the limiting baffle 14. That is to say, while the limiting baffle 14 is directly connected to the inner wall surface of the housing assembly 1, it is also connected to the inner wall surface of the housing assembly 1 through the reinforcing structure 15. Therefore, the reinforcing structure 15 can effectively improve the connection strength between the limiting baffle 14 and the inner wall surface of the housing assembly 1, thereby ensuring the limiting effect of the limiting baffle 14 on the limiting mating part 23, so as to control the axial movement of the heat exchanger 2.

[0067] In a specific example, the limiting baffle 14 and the reinforcing structure 15 are integrally formed on the inner wall surface of the housing assembly 1. This simplifies the manufacturing process of the air conditioner 100, thereby improving its production efficiency. At the same time, it enhances the connection strength between the limiting baffle 14 and the reinforcing structure 15 and the inner wall surface of the housing assembly 1, ensuring the limiting effect of the limiting baffle 14 on the limiting mating part 23.

[0068] According to some embodiments of the present invention, the reinforcing structure 15 includes a first reinforcing rib 151, which extends along a first direction and is connected at both ends to the limiting baffle 14 and the first sidewall 11, respectively. That is, the first reinforcing rib 151 is supported on the side of the limiting baffle 14 facing away from the limiting mating portion 23 in the first direction, thereby providing better support for the limiting baffle 14 to prevent deformation of the limiting baffle 14 toward the first sidewall 11. This better maintains the position of the limiting baffle 14 in the first direction, ensuring the limiting effect of the limiting baffle 14 on the limiting mating portion 23 in the first direction.

[0069] According to some embodiments of the present invention, a plurality of first reinforcing ribs 151 are provided arranged along a second direction, which is perpendicular to the first direction. Therefore, by means of a plurality of first reinforcing ribs 151, the limiting baffle 14 can be supported at multiple locations in the second direction, thereby increasing the support strength of the reinforcing structure 15 on the limiting baffle 14, ensuring the structural stability of the limiting baffle 14, and improving the limiting effect of the limiting baffle 14 on the limiting mating part 23. In a specific example, two first reinforcing ribs 151 are provided arranged along the second direction. The dimension of the first reinforcing rib 151 in the third direction is smaller than the dimension of the limiting baffle 14 in the third direction. One first reinforcing rib 151 is supported on the side of the limiting plate 141 facing the first sidewall 11, and the other first reinforcing rib 151 is supported on the side of the second reinforcing plate 143 facing the first sidewall 11. Thus, the structural stability of the limiting plate 141 and the second reinforcing plate 143 in the first direction can be improved respectively by the two first reinforcing ribs 151.

[0070] According to some embodiments of the present invention, the reinforcing structure 15 further includes a second reinforcing rib 152, which is connected between the first reinforcing rib 151 and the first sidewall 11. In the direction toward the first sidewall 11, the second reinforcing rib 152 increases in size in a third direction, which is perpendicular to the first direction. That is, the second reinforcing rib 152 is supported between the first reinforcing rib 151 and the first sidewall 11, and the first reinforcing rib 151 and the second reinforcing rib 152 are supported between the limiting baffle 14 and the first sidewall 11. In the third direction, the size of the end of the second reinforcing rib 152 connected to the first sidewall 11 is larger than the size of the end of the second reinforcing rib 152 connected to the first reinforcing rib 151. Therefore, the connection position between the second reinforcing rib 152 and the first sidewall 11 can be increased more effectively, so that the impact force of the limiting baffle 14 on the limiting mating part 23 can be better distributed and transmitted to multiple locations on the first sidewall 11 through the first reinforcing rib 151 and the second reinforcing rib 152, thus ensuring the limiting effect of the limiting baffle 14 on the limiting mating part 23.

[0071] According to some embodiments of the present invention, the reinforcing structure 15 further includes a third reinforcing rib 153, one end of which is connected to the first reinforcing rib 151, and the other end of which is connected to the limiting baffle 14. That is, while the first reinforcing rib 151 is directly connected to the limiting baffle 14, it is also connected to the limiting baffle 14 via a second reinforcing rib 152. Therefore, the supporting position of the reinforcing structure 15 on the limiting baffle 14 can be increased, thereby enhancing the strengthening effect of the reinforcing structure 15 on the structural strength of the limiting baffle 14.

A first sidewall 11, a second sidewall 12, a third sidewall 16, and a fourth sidewall 17 are all formed on the chassis. The first and second sidewalls 11 and 12 are located on the right side of the heat exchanger 2, and the pipe space 13 is located on the right side of the first sidewall 11. The third and fourth sidewalls 16 and 17 are located on the rear side of the heat exchanger 2. Connecting posts are provided on the third and fourth sidewalls 16 and 17. Connecting lugs 25 are located at the rear end of the side plate 24, and a limiting fitting part 23 is located at the right end of the connecting lugs 25. Extending downwards, the connecting ear 25 is connected to the connecting post in the vertical direction. The limiting mating part 23 is located on the right side of the connecting ear 25, and the limiting baffle 14 is located on the right side of the limiting mating part 23. The lower end of the limiting plate 141 is connected to the fourth side wall 17. The rear end of the second reinforcing plate 143 is connected to the third side wall 16. The first reinforcing plate 142 is located at the connection position between the third side wall 16 and the fourth side wall 17. The reinforcing structure 15 is located on the right side of the limiting baffle 14 and the left side of the first side wall 11. The first reinforcing rib 151 extends in the front-back direction, the second reinforcing rib 152 is triangular, and the third reinforcing rib 153 extends in the front-back direction.
