Embodiment one:

Referring to fig. 1-8 and fig. 16-41, an embodiment of the disclosure provides a cover 1 for an outdoor unit 100 of an air conditioner, where the cover 1 is adapted to cover an air outlet 21 of the outdoor unit 100.

The outdoor unit 100 includes a casing 2, and the casing 2 is provided with an air inlet and an air outlet 21. The outdoor unit 100 further includes a compressor, an outdoor heat exchanger, and a blower 6, all of which are located in the casing 2. The fan 6 drives air to enter the shell 2 from the air inlet and then exchange heat with the outdoor heat exchanger, and then the air is blown out from the air outlet 21.

The cover 1 includes a frame 11 and a protection net 12.

The frame 11 encloses an installation space, the protective screen 12 is arranged in the installation space and covers the fan 6, the protective screen 12 is of a net structure with cross transverse grids and cross longitudinal grids, wherein an opening groove 1111 is formed in the inner edge 1116 of the frame 11, and the inner edge 1116 of the frame 11 refers to the edge of the frame 11 facing the installation space.

The provision of the opening groove 1111 can reduce the area of the inner edge 1116 of the frame 11, thereby reducing the shielding area of the frame 11 to the air outlet 21, reducing the wind resistance of the air outlet of the fan 6, and reducing the noise of the outdoor unit 100. In addition, after the wind resistance is reduced, the rotation speed of the fan 6 can be reduced under the condition that the air output of the fan 6 is constant, and the noise of the outdoor unit 100 can be further reduced.

The inner edge 1116 of the frame 11 is closer to the fan 6 than other structures on the frame 11, with the greatest impact on the air out of the fan 6. Therefore, the noise reduction effect is more remarkable when the opening groove 1111 is provided at the inner edge 1116 than when the opening groove 1111 is provided at other positions than the inner edge 1116 on the frame 11. Also, in the case where the size and shape of the open groove 1111 are fixed, the loss of strength of the frame 11 at the edge of the frame 11 is smaller than when the open groove 1111 is provided at the middle of the frame 11. Therefore, the opening groove 1111 is arranged on the inner edge 1116 of the frame 11, so that the air outlet resistance of the air outlet 21 can be reduced and the noise of the whole machine can be reduced on the premise of ensuring the structural strength of the frame 11.

Optionally, the frame 11 comprises a first cross member 111, a second cross member 112 and a longitudinal member 113.

The second beam 112 is disposed opposite to the first beam 111, and the protection net 12 is located between the first beam 111 and the second beam 112.

The number of fans 6 is plural, and as shown in fig. 28, the number of fans 6 is two. The two fans 6 are disposed in this order along the length direction of the first beam 111 and the second beam 112. As shown in fig. 1 and 2, the stringers 113 are provided between the first and second cross members 111 and 112 to enhance the overall strength of the frame 11.

The number of the protection nets 12 is equal to that of the fans 6 and corresponds to that of the fans one by one, and the longitudinal beams 113 are positioned between two adjacent protection nets 12.

The inner edges of the frame include an inner edge 1116 of the first cross member 111, an inner edge 1116 of the second cross member 112, and an inner edge 1116 of the stringers 113. At least one of the inner edge 1116 of the first cross member 111, the inner edge 1116 of the second cross member 112 and the inner edge 1116 of the side member 113 is provided with an open slot 1111. As shown in fig. 2, the inner edge 1116 of the first cross member 111, the inner edge 1116 of the second cross member 112, and the inner edge 1116 of the side member 113 are each provided with an open groove 1111.

The inner edge 1116 of the first beam 111, the inner edge 1116 of the second beam 112 and the inner edge 1116 of the longitudinal beam 113 can shield the air outlet of the fan 6, so that the air outlet resistance of the fan 6 can be reduced by arranging the open slot 1111 on at least one of the inner edge 1116 of the first beam 111, the inner edge 1116 of the second beam 112 and the inner edge 1116 of the longitudinal beam 113.

Optionally, as shown in fig. 38, the outdoor unit 100 further includes a wind guiding ring 5, the wind guiding ring 5 is located in the casing 2, and the fan 6 is located in the wind guiding ring 5. In an orthographic projection of the frame 11 on the wind-guiding ring 5, the opening groove 1111 is located at least partially inside the wind-guiding ring 5.

In the orthographic projection of the frame 11 on the plane perpendicular to the axis of the wind guiding ring 5, the part of the frame 11 located at the inner side of the wind guiding ring 5 is more serious in shielding the wind, and the effect of reducing the wind resistance of the fan 6 is more obvious by arranging the opening groove 1111 at the part. When the open groove 1111 is provided in this portion, at least part of the open groove 1111 is located inside the air guide ring 5 in the front projection of the frame 11 on the air guide ring 5.

The number of the first cross beams 111 and the second cross beams 112 is multiple, and the number of the first cross beams and the number of the second cross beams are equal to the number of the fans 6. The plurality of first cross beams 111 are connected and are each sequentially arranged along the arrangement direction of the plurality of fans 6, and the plurality of second cross beams 112 are connected and are each sequentially arranged along the arrangement direction of the plurality of fans 6. As shown in FIG. 2, the number of the first cross beams and the second cross beams is two, and the number of the first cross beams and the second cross beams are equal to the number of the fans and correspond to one another.

A first cross member 111, a second cross member 112 and a longitudinal member 113 enclose an installation space, and a protection net 12 is located in the installation space.

The plurality of first beams 111 are connected, or the plurality of first beams 111 are of a unitary structure.

The plurality of second beams 112 are connected, or the plurality of second beams 112 are of unitary construction.

The opening groove 1111 is provided in the middle of the first beam 111, the second beam 112, and the longitudinal beam 113 in the longitudinal direction, and is provided corresponding to the axis of the fan 6. The middle parts of the first cross beam 111, the second cross beam 112 and the longitudinal beam 113 in the length direction correspond to the axis of the fan 6, and wind resistance caused by the position is large, so that the opening groove 1111 is arranged at the position, and the wind resistance reducing effect is remarkable.

The opening 1111 may have various shapes, for example, as shown in fig. 3, an elongated shape, and the length direction of the elongated shape is the length direction of the first cross member 111 where it is located, or the length direction of the longitudinal beam 113 where it is located.

In providing the shape and size of the open groove 1111, it is necessary to comprehensively consider the wind resistance and the structural strength of the frame 11.

Optionally, the bottom wall of the opening groove 1111 is provided with a reinforcing structure to enhance the strength of the frame 11, so as to avoid a large influence on the strength of the frame 11 due to the arrangement of the opening groove 1111.

Alternatively, the reinforcing structure includes a plurality of reinforcing ribs 1112 as shown in fig. 3, 18 and 20, and the plurality of reinforcing ribs 1112 are sequentially arranged along the length direction of the open slot 1111 to form a zigzag shape.

Compared with the reinforcing ribs 1112, the reinforcing ribs 1112 are arranged in the scheme, and the size of each reinforcing rib 1112 can be reduced on the premise of meeting the structural strength of the frame 11, so that the reinforcing ribs 1112 are prevented from greatly influencing the air outlet.

The ratio of the length of each reinforcing rib 1112 to the length of the open groove 1111 is greater than or equal to one third and less than or equal to three quarters, achieving a relative balance between reducing wind resistance and increasing the strength of the frame 11.

The reinforcing ribs 1112 are rectangular, triangular or any shape and are within the scope of the present application.

In a particular embodiment, the reinforcing ribs 1112 extend toward the guard net 12. This can enhance the strength of the frame 11 and reduce the wind resistance caused by the reinforcing ribs 1112 as small as possible.

As shown in fig. 18 and 20, the reinforcing ribs 1112 are provided perpendicularly to the bottom wall of the open groove 1111 where they are located.

In another specific embodiment, the reinforcing ribs 1112 are bent toward the inside of the housing 2 to form the reinforcing ribs 1112.

Compared with the reinforcing ribs 1112 extending towards the protective net 12, the reinforcing ribs 1112 can further strengthen the strength of the frame 11 towards the inside of the shell 2 by bending, and shielding of the reinforcing ribs 1112 to air outlet of the fan 6 is reduced, so that wind resistance is further reduced.

The number of the reinforcing ribs 1112 may be one or more. As shown in fig. 3, when the number of the reinforcing ribs 1112 is plural, the plural reinforcing ribs 1112 are disposed in order along the longitudinal direction of the open groove 1111.

As shown in fig. 7 and 8, the number of the reinforcing ribs 1112 is one, one end in the longitudinal direction of the reinforcing ribs 1112 is connected to one groove side wall of the open groove 1111, and the other end in the longitudinal direction of the reinforcing ribs 1112 is connected to the other groove side wall of the open groove 1111. The connection of the ribs 1112 to the side walls of the open slot 1111 forms an arc transition (e.g., X and Y in fig. 7), which can further enhance the strength of the frame 11 as compared to the connection of the ribs 1112 to the side walls of the open slot 1111. The arc transition may be performed by using one arc, or may be a plurality of arcs connected end to end, and the plurality of arcs are sequentially arranged along a direction from the reinforcing rib 1112 to the groove sidewall of the open groove 1111.

The setting of strengthening rib 1112 for form the air-out space between frame 11 and the protection network 12, reduced the shielding of frame 11 to fan 6 air-out, reduced the air-out resistance, strengthening rib 1112 can also strengthen the intensity of frame 11 moreover.

The ribs 1112 may also be bent in a direction away from the interior of the housing 2. As shown in fig. 26, the direction facing away from the interior of the housing 2 is upward.

Optionally, the end of the rib 1112 facing away from the bottom wall of the slot 1111 is located outside the inner edge 1116 of the frame 11 where it is located.

When the reinforcing rib 1112 is provided on the first cross member 111, one end of the reinforcing rib 1112 facing away from the groove bottom wall of the opening groove 1111 is located outside the inner edge 1116 of the first cross member 111, i.e., the reinforcing rib 1112 does not extend to the inner edge 1116 of the first cross member 111, when the reinforcing rib 1112 is provided on the second cross member 112, one end of the reinforcing rib 1112 facing away from the groove bottom wall of the opening groove 1111 is located outside the inner edge 1116 of the second cross member 112, i.e., the reinforcing rib 1112 does not extend to the inner edge 1116 of the second cross member 112, and when the reinforcing rib 1112 is provided on the side member 113, one end of the reinforcing rib 1112 facing away from the groove bottom wall of the opening groove 1111 is located outside the inner edge 1116 of the side member 113, i.e., the reinforcing rib 1112 does not extend to the inner edge 1116 of the side member 113. Wherein, the direction close to the axis of the fan 6 is the inner direction, and the direction far away from the axis of the fan 6 is the outer direction. Thereby reducing wind drag caused by the ribs 1112.

As shown in fig. 4, the side member 113 includes a first connection section 1131, a second connection section 1132, and a third connection section 1133, and the first connection section 1131, the second connection section 1132, and the third connection section 1133 are sequentially disposed along the width direction of the side member 113. The second connection section 1132 is lower than the first connection section 1131 and the third connection section 1133. The stringer 113 further includes a first transition section 1134 and a second transition section 1135, the first transition section 1134 being connected between the first connection section 1131 and the second connection section 1132, the second transition section 1135 being connected between the second connection section 1132 and the third connection section 1133.

The second connection section 1132 is provided with a through hole 1136, and the through hole 1136 is formed by adopting a stretching process. On the one hand, the through holes 1136 can reduce wind resistance, and on the other hand, the through holes 1136 can enhance the structural strength of the stringers 113.

The through hole 1136 is elongated, and the extending direction of the through hole 1136 is consistent with the length direction of the longitudinal beam 113. The number of the through holes 1136 is plural, and the plural through holes 1136 are sequentially arranged along the longitudinal direction of the side member 113. The through holes 1136 may be holes with other shapes, and the number of the through holes 1136 may be one, which is within the protection scope of the present application.

Optionally, the frame 11 is provided with a flow guiding structure to guide the fan 6 to air out towards the air outlet 21.

The flanges are bent with the inner edge 1116 of the frame 11, and may be perpendicular to the inner edge 1116 of the frame 11 or may not be perpendicular to the inner edge 1116. For example, in the opposite direction of the air outlet of the fan 6, the flange is inclined towards the direction away from the axis of the fan 6, as shown in fig. 5 to 7, so as to reduce the shielding of the flange on the air outlet of the fan 6 and enhance the flow guiding effect of the flange on the air outlet of the fan 6.

Compared with the second inner edge 1118, the first inner edge 1117 is arranged corresponding to the wind guiding ring 5, that is, corresponding to the axis of the fan 6, the wind resistance caused by the wind outlet of the fan 6 is larger, and therefore, compared with the effect of enhancing the strength of the frame 11, the first flange 1114 should achieve the effect of reducing the wind resistance. The second flange 1115 has less influence on wind resistance, and therefore, the second flange 1115 should have an effect of enhancing the strength of the frame 11 more than reducing wind resistance. Thus, the first flange 1114 is disposed outside the second flange 1115, wherein the direction toward the middle of the housing 2 is inward and the direction away from the middle of the housing 2 is outward.

And the wind-guiding ring 5 is located outside the first beam section 31 compared to the wind-guiding ring 5 being located inside the first beam section 31, so that the wind-guiding ring 5 also has a larger inner diameter. The wind-guiding ring 5 can accommodate the fan 6 blades 61 with maximized radial dimension, and the fan 6 can be installed in the wind-guiding ring 5. And dodge the setting in groove 311, can reduce the shielding of first roof beam section 31 to fan 6 air-out, reduce the air-out windage.

The cross section of the first wind guiding section 51 is non-circular, for example rectangular or nearly rectangular.

Wherein, the inner wall surface of the first wind guiding section 51 protrudes outwards to form a protruding part 5121, so as to avoid the interference between the blades 61 of the fan 6 and the first wind guiding section 51.

The provision of the boss 5121 can increase the distance between the position on the inner wall surface of the first wind guiding section 51 where the boss 5121 is provided and the axis of the wind guiding ring 5, thereby avoiding interference between the blades 61 of the fan 6 and the first wind guiding section 51. This increases the diameter of the blades 61 of the fan 6, and maximizes the diameter of the blades 61 of the fan 6. Therefore, under the condition that the air output of the fan 6 is constant, the rotating speed of the fan 6 can be reduced, and the air supply noise of the fan 6 is reduced.

As shown in fig. 38 to 41, in the top-outlet outdoor unit 100, the first air guide section 51 is provided below the second air guide section 52. The boss 5121 is provided to interfere with the first wind guide section 51 mainly during rotation of the tip portion of the placement blade 61.

The number of the fans 6 is multiple, and the number of the wind guide rings 5 is equal to and corresponds to the number of the fans 6 one by one. In other words, a fan 6 is disposed in one wind guiding ring 5, and one fan 6 is located between one wind guiding ring 5.

The first wind guide section 51 includes a first wind guide wall 511 and a second wind guide wall 512.

The first wind guiding wall 511 is opposite to the adjacent fan 6, the second wind guiding wall 512 and the first wind guiding wall 511 are sequentially arranged along the circumferential direction of the first wind guiding section 51, the second wind guiding wall 512 is connected with the first wind guiding wall 511, a folding angle is formed at the connecting position, and the protruding part 5121 is arranged on the second wind guiding wall 512.

For convenience of description, two of the plurality of fans 6 are named as a first fan 6 and a second fan 6, respectively, and corresponding two of the plurality of air guide rings 5 are named as a first air guide ring 5 and a second air guide ring 5, respectively. The first fan 6 is located in the first air guide ring 5, and the second fan 6 is located in the second air guide ring 5.

The first air guiding wall 511 of the first air guiding ring 5 is arranged opposite to the second fan 6, and the second air guiding wall 512 of the second air guiding ring 5 is arranged opposite to the first fan 6.

The number of the second air guiding walls 512 is two, the two second air guiding walls 512 are oppositely arranged, the number of the first air guiding walls 511 is also two, and the two first air guiding walls 511 are oppositely arranged.

The outdoor unit 100 has a large dimension in the direction of the line connecting the two first air guide walls 511 (the longitudinal direction of the outdoor unit 100), and the first air guide walls 511 are spaced a large distance from the axis of the air guide ring 5 where they are located, so that they do not interfere with the blades 61. The outdoor unit 100 has a small size in the connecting direction of the two second air guide walls 512 (the width direction of the outdoor unit 100), resulting in a small axial distance between the second air guide walls 512 and the air guide ring 5. Therefore, the dimensions of blades 61 are primarily limited by the distance between second wind guide wall 512 and the axis of wind-guiding ring 5.

The boss 5121 is provided on the second air guide wall 512, and increases the distance between the second air guide wall 512 and the axis of the air guide ring 5, so that the diameter of the blade 61 can be increased.

The distance between the middle part of the second air guiding wall 512 in the length direction and the axis of the air guiding ring 5 is smaller than the distance between the end part of the second air guiding wall 512 in the length direction and the axis of the air guiding ring 5, so that the middle part of the second air guiding wall 512 in the length direction is easier to interfere with the blades 61, and therefore, the protruding part 5121 is arranged at the middle part of the second air guiding wall 512 in the length direction.

It will be appreciated that the boss 5121 may also extend to the lengthwise end of the second air guiding wall 512.

The inner surface of the boss 5121 is spaced from the axis of the wind-guiding ring 5 by a distance equal to half the inner diameter of the second wind-guiding section 52.

If the distance between the inner surface of the boss 5121 and the axis of the wind-guiding ring 5 is less than half of the inner diameter of the second wind-guiding section 52, the size of the vane 61 is still limited at the boss 5121, so that the size of the vane 61 cannot reach the maximum diameter of the vane 61 that can be accommodated at the first wind-guiding section 51 or the first wind-guiding wall 511, and if the distance between the inner surface of the boss 5121 and the axis of the wind-guiding ring 5 is greater than half of the inner diameter of the second wind-guiding section 52, the size of the boss 5121 protruding outwards is excessively large, resulting in the size of the outdoor unit 100 in the width direction.

Therefore, the distance between the inner surface of the boss 5121 and the axis of the air guide ring 5 is equal to half of the inner diameter of the second air guide section 52, so that the diameter of the vane 61 can be maximized without excessively increasing the width dimension of the outdoor unit 100.

In the orthographic projection of the wind-guiding ring 5 on the preset plane, the outer surface of the protruding portion 5121 is tangent to the outer surface of the second wind-guiding segment 52.

If the distance between the outer surface of the boss 5121 and the axis of the wind-guiding ring 5 is less than half of the outer diameter of the second wind-guiding section 52, the size of the vane 61 is still limited at the boss 5121, so that the size of the vane 61 cannot reach the maximum diameter of the vane 61 that can be accommodated at the first wind-guiding section 51 or the first wind-guiding wall 511, and if the distance between the outer surface of the boss 5121 and the axis of the wind-guiding ring 5 is greater than half of the outer diameter of the second wind-guiding section 52, the size of the boss 5121 protruding outwards is excessively large, resulting in the size of the outdoor unit 100 in the width direction being excessively large.

Therefore, the distance between the outer surface of the boss 5121 and the axis of the air guide ring 5 is equal to half of the outer diameter of the second air guide section 52, so that the diameter of the vane 61 can be maximized without excessively increasing the width dimension of the outdoor unit 100.

The protruding arm 5124 is connected between the other end of the first connection arm 5122 and the other end of the second connection arm 5123.

Wherein, the protruding arm 5124 is planar, and the planar structure is easy to be formed, thereby reducing the processing cost of the wind guiding ring 5. And the plane is parallel to the axis of the wind-guiding ring 5, so that the protruding arm 5124 does not interfere with the blade 61 everywhere.

It will be appreciated that the projecting arm 5124 may take other shapes, such as an arc shape of the projecting arm 5124, wherein the center of the arc is located on the axis of the air guiding ring 5.

Embodiment two:

The difference from the first embodiment is that, as shown in fig. 9 to 15, the side member 113 is tubular, and the tube extends in the direction from the first cross member 111 to the second cross member 112.

The main function of the stringers 113 is to strengthen the frame 11, and therefore the strength index of the stringers 113 is important. In the case where the width of the side members 113 is the same, the tubular side members 113 have higher strength than the plate-like side members 113. Therefore, when the strength of the longitudinal beam 113 is constant, the width of the tubular longitudinal beam 113 can be reduced, so that the shielding of the longitudinal beam 113 to the air outlet can be reduced, and the air resistance of the air outlet of the fan 6 can be reduced.

Optionally, stringers 113 are flat tubular.

Compared with a round tube, the flat tube has stronger deformation resistance, namely higher strength.

In the cross section of the first flat pipe section 1137, the dimension along the air outlet direction of the fan 6 is larger than the dimension along the direction perpendicular to the air outlet direction, so that the shielding area of the first flat pipe section 1137 to the air outlet 21 is reduced, and the air outlet resistance of the fan 6 is reduced.

Optionally, the stringer 113 further includes a second flat tube segment 1138, the second flat tube segment 1138 being connected to the first flat tube segment 1137. The second flat tube section 1138 and the first flat tube section 1137 are sequentially arranged along the length direction of the longitudinal beam 113, wherein the dimension along the air outlet direction of the fan 6 is smaller than the dimension along the direction perpendicular to the air outlet direction in the cross section of the second flat tube section 1138.

The second flat tube section 1138 is staggered with the fan 6, so that the influence of the second flat tube section 1138 on the air outlet is small, and the strength enhancement of the second flat tube section 1138 on the longitudinal beam 113 is more needed to be considered.

Taking the outdoor unit 100 as an example of top-outlet type, the longitudinal beam 113 is located above the fan 6, and the air outlet direction of the fan 6 is upward. The first flat tube segment 1137 has a smaller dimension in the horizontal direction (perpendicular to the air-out direction) than in the up-down direction (along the air-out direction). The second flat tube segment 1138 has a dimension in the horizontal direction (perpendicular to the air-out direction) that is greater than the dimension in the up-down direction (along the air-out direction). This can give the stringers 113 greater strength.

Optionally, the first flat tube segment 1137 is hollow, or is solid, or is partially hollow, and partially solid. The solid structure is shown in fig. 12, and the hollow structure is shown in fig. 13 to 15.

The strength of the first flat tube section 1137 can be enhanced by adopting a solid structure, and the cost of the first flat tube section 1137 can be reduced by adopting a hollow structure.

When the first flat tube section 1137 is partially of a hollow structure and partially of a solid structure, the hollow structure and the solid structure are alternately arranged along the length direction of the first flat tube section 1137.

Optionally, the second flat tube segment 1138 is hollow, or is solid, or is partially hollow, and partially solid.

The strength of the second flat tube section 1138 can be enhanced by adopting a solid structure, and the cost of the second flat tube section 1138 can be reduced by adopting a hollow structure.

When the second flat tube section 1138 is partially of a hollow structure and partially of a solid structure, the hollow structure and the solid structure are alternately arranged along the length direction of the second flat tube section 1138.

Optionally, the connection between the first flat tube section 1137 and the second flat tube section 1138 adopts a smooth transition, so that on one hand, the strength of the longitudinal beam 113 can be enhanced, and on the other hand, the wind resistance caused by the longitudinal beam 113 can be reduced.

Optionally, the stringer 113 further includes a transition tube section 1139, the transition tube section 1139 being connected between the first flat tube section 1137 and the second flat tube section 1138, the transition tube section 1139 having a circular cross section.

The junction of first flat tube section 1137 and second flat tube section 1138 includes transition tube section 1139, and transition tube section 1139 is the pipe for realized smooth transition from second flat tube section 1138 to first flat tube section 1137, but not abrupt change, the fan 6 air-out resistance increase that avoids abrupt change to lead to.

The dimension of the first flat tube section 1137 along the direction perpendicular to the air outlet direction is smaller than the dimension of the second flat tube section 1138 along the direction perpendicular to the air outlet direction, so that the air outlet wind resistance can be reduced by means of the first flat tube section 1137 along the direction perpendicular to the air outlet direction, and the strength of the longitudinal beam 113 can be increased by means of the second flat tube section 1138 along the direction perpendicular to the air outlet direction.

The longitudinal beam 113 further comprises a connecting pipe section 1140, wherein the connecting pipe section 1140 is arranged at one end of the second flat pipe section 1138, which is away from the first flat pipe section 1137, and is suitable for being connected with the first beam 111 or the second beam 112, and the ratio of the dimension of the connecting pipe section 1140 along the air outlet direction (along the upper box direction) to the dimension perpendicular to the air outlet direction (along the horizontal direction) is smaller than the ratio of the dimension of the second flat pipe section 1138 along the air outlet direction to the dimension perpendicular to the air outlet direction, i.e. the flat degree of the connecting pipe section 1140 is greater than the flat degree of the second flat pipe section 1138, so that the connecting pipe section 1140 is convenient to be connected with the first beam 111 or the second beam 112.

The second flat tube segment 1138 may have a plate shape, wherein the thickness direction of the plate extends in the air outlet direction, the width direction of the plate is perpendicular to the air outlet direction, and the width direction of the plate is greater than the thickness direction of the plate.

The longitudinal beam 113 is clamped and/or screwed with the first cross beam 111, and the longitudinal beam 113 is clamped and/or screwed with the second cross beam 112.

In the case of a screw connection, the screw passes through the connecting tube section 1140 in the air-out direction.

The connection tube section 1140 is a solid structure to enhance the connection strength of the connection tube section 1140 to the first beam 111 and/or to the second beam 112.
