DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0028] In the description of the present application, it should be understood that the terms "height", "thickness", "upper", "lower", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, the meaning of "multiple" is two or more, at least one of which can be one, two or more, unless otherwise explicitly specified.

[0029] It should also be noted that in the drawings of the embodiments of the present application, the arrow marked X represents the first direction X, the arrow marked Y represents the second direction Y, and the arrow marked Z represents the third direction Z. The first direction X, the second direction Y and the third direction Z are introduced to more clearly describe the structure and relative positional relationship of the components in the wall hanging device. In actual application, the first direction X, the second direction Y and the third direction Z may change according to the different placement modes of the wall hanging device.

[0030] As a preamble of the embodiments of the present application, the power converter in the related art is usually fixed on the wall surface, support or other support structure by bolts, and the posture of the power converter or the relative position between the power converter and the support structure is fixed. However, various situations will be encountered in actual installation process. For example, gravity type thermosyphon heat dissipation structure is used in the power converter, and the condensate in the heat dissipation structure relies on its own gravity to return, so the power converter needs to be installed obliquely to make the condensation channel oblique and cooperate with the gravity to accelerate the return of the condensate. Or, there are obstacles around the power converter, and the inclination of the power converter needs to be adjusted to avoid the obstacles so as to avoid that the air vent is blocked. Or, the power converter has a certain inclination to utilize the inclined surface to reduce the accumulation of dust and moisture. Or, the power converter needs to be fine-tuned in the case that the support structure has been installed to optimize the overall stress and reasonably utilize the surrounding space. Therefore, the existing installation method cannot fully adapt to the changes of different installation environments and has poor flexibility.

[0031] The present application provides a wall hanging device, please refer to Figure 1 and Figure 2 The wall hanging device comprises a support assembly 1 and at least one of a first adjusting assembly 3 and a lifting assembly 6, and the support assembly 1 is used for supporting the power converter 5.

[0032] The first adjusting assembly 3 comprises a matching part 31 and an adjusting part 32, the adjusting part 32 is arranged on the matching part 31 and is configured to be movable relative to the matching part 31 to push the lower handle 4 of the power converter 5 to rotate the power converter 5. The matching part 31 can be arranged independently of the support assembly 1, or the matching part 31 can be arranged on the support assembly 1. The movement of the adjusting part 32 relative to the matching part 31 can be one or a combination of linear movement and rotational movement.

[0033] The lifting assembly 6 is arranged on the support assembly 1, and the support assembly 1 is configured to be connected with the upper handle 2 of the power converter 5 through the lifting assembly 6 to drive the power converter 5 to lift.

[0034] The first adjusting assembly 3 can push the lower handle 4 of the power converter 5 to rotate the power converter 5, so as to adjust the angle of the power converter 5 and make the power converter 5 form a certain included angle with the support assembly 1. The lifting assembly 6 can adjust the height position of the power converter 5. By selectively arranging the first adjusting assembly 3 and the lifting assembly 6, the height and angle of the power converter 5 can be selectively adjusted, so that the power converter 5 can adapt to the changes of the installation environment and meet different installation requirements in different postures and different relative positions, thereby improving the flexibility of the installation of the power converter 5.

[0035] In some embodiments, the support assembly 1 is arranged along the direction of gravity, the power converter 5 includes a heat generating element and a thermosyphon heat dissipation structure, the heat generating element can be a power module, a circuit board, a chip or the like electrical component, and the thermosyphon heat dissipation structure is in thermal connection with the heat generating element to dissipate heat from the heat generating element. By adjusting the portion 32 to push the lower portion of the power converter 5, such as rotating the lower handle 4 of the power converter 5, the power converter 5 is formed in an inclined posture, and in the thermosyphon heat dissipation structure, the side of the condensation channel inclined downward faces the evaporation cavity, so that the backflow speed of the condensate is accelerated, which is beneficial to improving the heat dissipation efficiency.

[0036] Referring to Figure 1 and Figure 2 In some embodiments, the fitting portion 31 is arranged on the support assembly 1, and the adjusting portion 32 is arranged through the fitting portion 31 and is in threaded connection with the fitting portion 31. Specifically, the fitting portion 31 has an internal threaded hole, and the adjusting portion 32 has an external threaded segment arranged through the internal threaded hole, and the threaded connection between the adjusting portion 32 and the fitting portion 31 is achieved by the cooperation between the external threaded segment and the internal threaded hole. In the process of screwing the adjusting portion 32, the adjusting portion 32 rotates around its own axis and moves along the axis, which is a combination of rotary motion and linear motion. The threaded structure of the adjusting portion 32 and the fitting portion 31 can achieve self-locking and has high position accuracy.

[0037] Referring to Figure 1 and Figure 2 In some embodiments, the adjusting portion 32 is arranged along the first direction X, that is, the length direction of the adjusting portion 32 is in the same direction as the first direction X, and the first direction X is the arrangement direction of the power converter 5 and the support assembly 1. The adjusting portion 32 includes an end surface and an external threaded surface connected with each other, and the end surface of the adjusting portion 32 abuts against the lower handle 4. In this embodiment, the fitting portion 31 can be a press rivet nut which is fixed on the side of the support assembly 1 away from the lower handle 4 through a press riveting process, so that the axis of the fitting portion 31 is located on the first direction X. The threaded structure of the adjusting portion 32 and the fitting portion 31 can convert a small rotary torque into a large linear thrust, which increases the convenience of pushing the lower handle 4.

[0038] In other embodiments, the fitting portion 31 can also be other structural members with an internal threaded hole, which can be fixed with the support assembly 1 through riveting, welding, buckle connection or the like.

[0039] Referring to Figure 1 and Figure 2 In some embodiments, the number of the fitting portions 31 is multiple, and the multiple fitting portions 31 are arranged at intervals along the second direction Y, which is the direction of gravity and intersects with the first direction X. The multiple fitting portions 31 are arranged at equal distances, so that the adjusting portion 32 can select the corresponding fitting portion 31 according to the position of the lower handle 4 to connect with it, so as to ensure that the adjusting portion 32 can effectively contact the lower handle 4.

[0040] Referring to Figure 3 , Figure 4 and Figure 5 In some embodiments, the fitting part 31 is provided as a plurality of through holes 111, which are arranged along the first direction X on the support assembly 1, and the first direction X is the arrangement direction of the power converter 5 and the support assembly 1. The adjusting part 32 is arranged through the through hole 111 and detachably connected with the support assembly 1, and the adjusting part 32 is used to abut against the lower handle 4. The plurality of through holes 111 arranged along the first direction X means that the overall trend of the arrangement of the plurality of through holes 111 is dispersed along the first direction X, so the plurality of through holes 111 can be arranged in a straight line along the first direction X, or can be arranged in a broken line or a curve. When the adjusting part 32 is arranged through the through hole 111, the adjusting part 32 is on the movement path of the lower handle 4, which ensures that the adjusting part 32 can abut against the lower handle 4.

[0041] In order to realize that the adjusting part 32 can be fixed with the support assembly 1 and can be detached, in one implementation, the adjusting part 32 can be connected with the through hole 111 in an interference fit manner, at this time the cross-sectional shape of the adjusting part 32 is matched with the inner contour of the through hole 111, and the through hole 111 can be circular, oval or polygonal. In another implementation, the adjusting part 32 can be threadedly connected with the through hole 111, or the adjusting part 32 is connected in cooperation with a bolt and a nut.

[0042] By arranging the adjusting part 32 in different through holes 111, the distance between the adjusting part 32 and the lower handle 4 can be adjusted, so as to change the included angle between the power converter 5 and the support assembly 1, which is convenient and fast. In the case of installing the support assembly 1 by wall hanging, the first adjusting assembly 3 is arranged on one side of the support assembly 1 along the third direction Z, which can avoid the object of wall hanging, and facilitate the adjustment of the first adjusting assembly 3. The third direction Z is parallel to the rotation axis of the power converter 5 and intersects the first direction X and the second direction Y.

[0043] Referring to Figure 4 and Figure 5In some embodiments, the through hole 111 extends along a second direction Y, which is the direction of gravity and intersects the first direction X. The adjusting part 32 includes a fastening bolt 321 and a fastening nut 322, the fastening bolt 321 is arranged in the through hole 111 and is threadedly connected with the fastening nut 322, the head of the fastening bolt 321 and the fastening nut 322 are distributed on both sides of the through hole 111 and abut against the support assembly 1, so that the adjusting part 32 is fixed with the support assembly 1. The outer circumferential surface of the fastening bolt 321 abuts against the lower handle 4. The adjusting part 32 can move up and down along the through hole 111, which increases the adjustable range of the position of the adjusting part 32. When the end surface of the lower handle 4 abuts against the adjusting part 32 and the end surface is inclined, the lower handle 4 can be pushed by moving the adjusting part 32 up and down, so as to fine-tune the lower handle 4.

[0044] Please refer to Figure 6 In some embodiments, the adjusting part 32 is rotationally connected to the support assembly 1, and the rotation axis of the adjusting part 32 is arranged along a third direction Z, that is, the rotation axis is parallel to the third direction Z. The lower handle 4 is located on the rotation path of the adjusting part 32 and abuts against the adjusting part 32. The adjusting part 32 is configured to push the lower handle 4 to move during rotation, so as to drive the power converter 5 to rotate. The matching part 31 includes a first fastener 325 for fixing the adjusting part 32. During the rotation of the power converter 5, the lower handle 4 can maintain abutment with the adjusting part 32, so that additional fixing actions of the power converter 5 can be avoided, thereby facilitating the convenience of adjusting the power converter 5.

[0045] In one implementation, the adjusting part 32 is arc-shaped, the first fastener 325 includes a bolt and a nut, the nut is arranged below the adjusting part 32 and is connected with the support assembly 1, the axis of the nut is arranged along the second direction Y, and the bolt is threadedly connected with the nut. The outer arc surface of the adjusting part 32 is provided with a plurality of limiting holes arranged at intervals in the circumferential direction, and the end of the bolt is inserted into one of the limiting holes to fix the adjusting part 32. Different limiting holes can correspond to different rotation angles of the adjusting part 32, so as to push the lower handle 4 to rotate by different angles. In another implementation, the adjusting part 32 has a mandrel 323, and the first fastener 325 includes a screw, which is threadedly connected with the support assembly 1 and abuts against the mandrel 323. By tightening the screw and abutting against the mandrel 323, the rotation of the mandrel 323 can be limited, so as to fix the adjusting part 32. Alternatively, the first fastener 325 includes a clamp and a bolt, and one clamp is arranged on each side of the mandrel 323. One of the clamps is fixed with the support assembly 1, and the two sides of the clamp are locked by the bolt, so that the two clamps tighten the mandrel 323 to limit the rotation of the mandrel 323, thereby fixing the adjusting part 32.

[0046] Please refer to Figure 6In some embodiments, the adjusting part 32 comprises a mandrel 323 and a first push block 324. The mandrel 323 is rotationally connected to the support assembly 1, and the rotation axis of the mandrel 323 is parallel to the rotation axis of the power converter 5, or it can also be understood that the axis of the mandrel 323 is arranged along the third direction Z. The first push block 324 is arc-shaped and fixed to the mandrel 323. The side wall of the first push block 324 is provided with arc-shaped holes 3241 distributed around the mandrel 323, and the arc-shaped holes 3241 are coaxially arranged with the mandrel 323. A first fastener 325 is arranged through the support assembly 1 and the arc-shaped holes 3241 to fix the first push block 324. Specifically, the first fastener 325 comprises a first bolt and a plurality of first nuts. The first bolt sequentially passes through the support assembly 1 and the arc-shaped holes 3241 along the third direction Z. The plurality of first nuts are arranged on both sides of the first push block 324 and are threadedly connected with the first bolt. The first push block 324 is rotated to drive the lower handle 4 to rotate the power converter 5. After the position of the power converter 5 is determined, the first nuts on both sides are tightened against the first push block 324, so that the first push block 324 is fixed, which is convenient and fast.

[0047] Referring to Figure 7 and Figure 8 In some embodiments, the matching part 31 is arranged as an adjusting hole 112. The adjusting hole 112 is arranged in the support assembly 1 and extends along the first direction X, which is the arrangement direction of the power converter 5 and the support assembly 1.

[0048] The adjusting part 32 comprises a second push block 326 and a second fastener 327. The second fastener 327 is arranged through the adjusting hole 112 and the second push block 326 to fix the second push block 326. The second push block 326 is used to abut against the lower handle 4. The second push block 326 can move along the adjusting hole 112 under the cooperation of the second fastener 327. The movement path of the second push block 326 can intersect with the movement path of the lower handle 4, so as to ensure that the second push block 326 abuts against the lower handle 4.

[0049] In this embodiment, the second fastener 327 comprises a second bolt and a second nut. The second nut can be fixed to the adjusting part 32 by riveting. The inner threaded hole of the second nut is in communication with the adjusting hole 112. The second push block 326 is locked and fixed by the threaded connection of the second bolt and the second nut. When the second push block 326 needs to be moved, the second bolt can be loosened or removed, which is simple and convenient. The second bolt can move along the adjusting hole 112 to change the position of the second push block 326, so as to change the pushing amplitude of the second push block 326 to the lower handle 4, so that the lower handle 4 can drive the power converter 5 to rotate by different angles. In addition, the threaded connection of the second bolt and the second nut can realize the fixation of the second push block 326 at any position of the adjusting hole 112, which is beneficial to increase the adjustable range.

[0050] Referring toFigure 7 In some embodiments, the first adjusting assembly 3 further comprises a positioning part 35, which is arranged in the first direction X through the support assembly 1 and is threadedly connected with the support assembly 1. The positioning part 35 abuts against the side of the second push block 326 away from the lower handle 4 to limit the movement of the second push block 326 towards the direction close to the positioning part 35. The abutment between the positioning part 35 and the second push block 326 causes the interaction of the thread engagement structure between the positioning part 35 and the support assembly 1 and forms self-locking, thereby limiting the backward movement of the second push block 326 and helping to improve the stability of the power converter 5 position.

[0051] Please refer to Figure 1 and Figure 2 In some embodiments, the wall hanging device comprises the first adjusting assembly 3 and does not comprise the lifting assembly 6, and the upper handle 2 is provided with a clamping groove 21 having a slot, and the slot is arranged downward in the second direction Y. The support assembly 1 is configured to be insertedly fitted with the upper handle 2 through the clamping groove 21, so that the power converter 5 is hung on the support assembly 1 through the upper handle 2. In the first direction X, the width of the clamping groove 21 is greater than the width of the part of the support assembly 1 located in the clamping groove 21. The first direction X is the arrangement direction of the power converter 5 and the support assembly 1, and the second direction Y is the direction of gravity and intersects with the first direction X. In this embodiment, the width of the clamping groove 21 is the minimum width thereof in the first direction X, and the cross section of the clamping groove 21 can be of different shapes, such as rectangular, trapezoidal, arc-shaped, etc. In the case that the cross section of the clamping groove 21 is rectangular, the minimum width of the clamping groove 21 is equal to the slot width; in the case that the cross section of the clamping groove 21 is trapezoidal, the minimum width of the clamping groove 21 is equal to the minimum distance between the two inner wall surfaces of the clamping groove 21 in the first direction X. Due to the existence of the fitting gap between the upper handle 2 and the support assembly 1 at the insertion position, the two have a certain degree of freedom at the insertion position, so that the upper handle 2 can rotate relative to the support assembly 1.

[0052] Please refer to Figure 9 and Figure 10 In some embodiments, the support assembly 1 comprises two main body parts 11 and a cross beam 12 connecting the two main body parts 11, and the cross beam 12 and the main body parts 11 can be fixed by welding, riveting, bolts, etc.

[0053] The main body part 11 comprises a plate 1100, a first bending section 1101 and a second bending section 1102 connected to the plate 1100. The number of the first bending sections 1101 is two, and the first bending sections 1101 are symmetrically arranged about the plate 1100. The plate 1100 and the first bending sections 1101 extend in the second direction Y. The adjusting part 32 is arranged at the lower end of the two first bending sections 1101.

[0054] The second bending section 1102 is arranged at the top end of the plate member 1100 and supported at the top end of the two first bending sections 1101. The second bending section 1102 extends along the first direction X. The top surface of the second bending section 1102 is provided with a matching hole 1103. The upper handle 2 is inserted into the matching hole 1103 through the clamping groove 21, so that the upper handle 2 is hung on the second bending section 1102. In order to increase the stability of the structure, the first bending section 1101 away from the plate member 1100 has a straight edge 1105 and two inclined edges 1106 distributed on both sides of the straight edge 1105. The straight edge 1105 is parallel to the second direction Y. The distance between the two inclined edges 1106 in the second direction Y gradually increases in the direction away from the plate member 1100, so that the first bending section 1101 is widened at the portions corresponding to the two inclined edges 1106, which can enhance the support strength of the main body part 11 at the top and bottom regions. Except for the side edge connected with the plate member 1100, the remaining side edges of the second bending section 1102 are respectively provided with downward turned edges 1104. The plurality of turned edges 1104 enclose the two first bending sections 1101.

[0055] The main body part 11 can be processed by sheet metal technology and partially widened to increase the structural strength, with high material utilization rate.

[0056] Please refer to Figure 1 and Figure 2 In some embodiments, the support assembly 1 includes two main body parts 11 arranged at intervals. The main body parts 11 extend along the second direction Y. Each main body part 11 corresponds to one upper handle 2 and one lower handle 4 of the power converter 5, that is, the power converter 5 is hung on the two main body parts 11 through the two upper handles 2. Among them, the main body part 11 is mainly enclosed by a plurality of plate bodies 117. One of the plate bodies 117 is arranged opposite to the upper handle 2, and the plate body 117 is a hanging plate 1171. The side of the hanging plate 1171 facing the upper handle 2 is provided with a clamping hole 1172. Part of the upper handle 2 is arranged in the clamping hole 1172. The hanging plate 1171 is inserted into the clamping groove 21 at the lower edge corresponding to the clamping hole 1172, so that the upper handle 2 is hung on the hanging plate 1171. At this time, in the first direction X, the width of the clamping groove 21 is greater than the width of the part of the support assembly 1 located in the clamping groove 21, that is, the width of the clamping groove 21 in the first direction X is greater than the thickness of the hanging plate 1171. Alternatively, the top end of the hanging plate 1171 is inserted into the clamping groove 21 along the second direction Y, so that the upper handle 2 is hung on the top end of the support assembly 1. On this basis, in order to limit the shaking of the upper handle 2 in the third direction Z, a downward recess can be arranged at the top end of the hanging plate 1171, so that the clamping groove 21 and the recess are buckled with each other, limiting the displacement of the upper handle 2 in the third direction Z, and improving the stability of the hanging.

[0057] The hanging structure of the upper handle 2 and the support assembly 1 enables the upper handle 2 to rotate relative to the support assembly 1 while being detachably connected with the support assembly 1, which facilitates the installation of the power converter 5.

[0058] In some other embodiments, the upper handle 2 can also be rotatably connected with the support assembly 1, for example through a rotating shaft, a hinge or the like.

[0059] Referring to Figure 1 In some embodiments, the main body 11 includes a plurality of plate bodies 117, which can be sequentially connected end to end, and the main body 11 has a closed polygonal cross section, and a through cavity is formed in the main body 11. The plurality of plate bodies 117 can also be sequentially connected, and a notch is formed between the first plate body 117 and the last plate body 117, and the main body 11 forms a cavity with the notch, and the notch is connected with the cavity. Among the plurality of plate bodies 117, the lengths of the plate bodies 117 can be the same or different, and similarly, the widths of the plate bodies 117 can be the same or different, which avoids interference with other structures.

[0060] Referring to Figure 1 and Figure 9 In some embodiments, the support assembly 1 is provided with a window structure 1173 on the side facing the lower handle 4, and the window structure 1173 is used for one of the lower handle 4 and the adjusting part 32 to pass through.

[0061] Referring to Figure 1 When the main body 11 includes a plurality of plate bodies 117, the hanging plate 1171 can cover the lower handle 4 in the orthographic projection along the first direction X, that is, part of the hanging plate 1171 is in the movement path of the lower handle 4, and the side wall of the hanging plate 1171 can be provided with a window structure 1173 for one of the lower handle 4 and the adjusting part 32 to pass through, so as to realize the abutment of the lower handle 4 and the adjusting part 32.

[0062] Referring to Figure 9 When the main body 11 includes two first bending sections 1101, the lower ends of the two first bending sections 1101 are spaced apart to form a window structure 1173 for the lower handle 4 to move through.

[0063] Referring to Figure 2 In some embodiments, when the power converter 5 is hung on the support assembly 1 through the upper handle 2, the wall hanging device further includes a second adjusting assembly 7, and the second adjusting assembly 7 includes a third fastener 71 which is threadedly connected to the support assembly 1, and the third fastener 71 is configured to be movable along the first direction X to push the upper handle 2 of the power converter 5, so as to rotate the power converter 5, and the first direction X is the arrangement direction of the power converter 5 and the support assembly 1.

[0064] In the embodiment, the third fastener 71 is threadedly connected with the support assembly 1, which can be a stud, a screw, a bolt or other threaded structure. The third fastener 71 abuts against the end face of the upper handle 2. The insertion position of the upper handle 2 with respect to the support assembly 1 corresponds to a fulcrum, forming a lever structure. Therefore, when the third fastener 71 exerts a pushing force on the end face of the upper handle 2, the upper handle 2 can be rotated, and in turn, the power converter 5 can be rotated. The second adjustment assembly 7 can cooperate with the first adjustment assembly 3 to achieve two-stage adjustment of the rotation angle of the power converter 5. In addition, the locking mechanism in the structure of the plurality of adjustment assemblies can fix the adjusted angle.

[0065] Please refer to Figure 11 In some embodiments, the lifting assembly 6 includes an adapter 14, an adjusting bolt 15 and a limiting part 16. The upper handle 2 is arranged on the adapter 14. The adjusting bolt 15 is arranged in the support assembly 1 and the adapter 14 along the second direction Y. The adjusting bolt 15 is threadedly connected with the support assembly 1. The end of the adjusting bolt 15 passing through the adapter 14 downward is connected with the limiting part 16, so that the adapter 14 is hung on the limiting part 16. The adapter 14 is configured to be movable along the second direction Y under the driving of the adjusting bolt 15. The second direction Y is the direction of gravity.

[0066] In an implementation manner, the main body part 11 of the support assembly 1 includes a first top plate 118 and a plurality of plate bodies 117. The plurality of plate bodies 117 are arranged around the outer periphery of the first top plate 118 and enclose a cavity, so that the inside of the main body part 11 is a hollow structure. One of the plate bodies 117 is arranged opposite to the upper handle 2, and the plate body 117 is a hanging plate 1171. The first top plate 118 is arranged at the top end of the plurality of plate bodies 117. The adapter 14 is arranged in the cavity. The adapter 14 includes a second top plate 143 and at least one side plate 140. The second top plate 143 is arranged at the top end of the side plate 140 along the second direction Y and is perpendicular to the side plate 140. The hanging plate 1171 is provided with a first avoiding hole 1174 penetrating along the first direction X. The first avoiding hole 1174 extends along the second direction Y. The end of the upper handle 2 away from the power converter 5 is arranged in the first avoiding hole 1174 and is movably connected with the side plate 140.

[0067] The top surface of the first top plate 118 is provided with a nut, and the adjusting bolt 15 is threadedly connected to the first top plate 118 through the nut. The first top plate 118 and the second top plate 143 are respectively provided with bolt holes for the adjusting bolt 15 to pass through, the limiting part 16 is arranged on the side of the second top plate 143 away from the first top plate 118, the limiting part 16 and the lower end of the adjusting bolt 15 are connected through a pin to limit the relative rotation therebetween, and the second top plate 143 is supported on the limiting part 16. The side plate 140 is in abutment with the hanging plate 1171 to limit the rotation of the adapter part 14. By rotating the adjusting bolt 15 to move it in the first direction X, the limiting part 16 moves synchronously with the adjusting bolt 15 and drives the second top plate 143 to move, so as to realize the lifting of the upper handle 2 and the power converter 5, and the adjustment is convenient, the position is accurate, and the load bearing capacity is large.

[0068] In another implementation manner, the top end of the hanging plate 1171 can also be arranged in space with the first top plate 118, and the top end of the hanging plate 1171 and the first top plate 118 form a space for avoiding, so as to directly connect the upper handle 2 with the adapter part 14. The number of the side plates 140 can also be multiple and arranged around the outer periphery of the second top plate 143 to increase the connection strength therebetween.

[0069] Please refer to Figure 11 In some embodiments, the upper handle 2 is provided with a clamping groove 21, the groove of the clamping groove 21 is arranged downward in the second direction Y, and the adapter part 14 is configured to be inserted and matched with the upper handle 2 through the clamping groove 21, so that the upper handle 2 of the power converter 5 is hung on the adapter part 14, and in the first direction X, the minimum width of the clamping groove 21 is greater than the width of the part of the adapter part 14 located in the clamping groove 21. The hanging structure of the upper handle 2 and the adapter part 14 enables the upper handle 2 to rotate relative to the adapter part 14 or to be detachably connected with the adapter part 14 while being able to move synchronously with the adapter part 14, which facilitates the installation of the power converter 5.

[0070] Please refer to Figure 11 In some embodiments, the wall hanging device further comprises a second adjusting assembly 7, the second adjusting assembly 7 comprises a third fastener 71, the third fastener 71 is threadedly connected to the adapter part 14, and the third fastener 71 is configured to be movable in the first direction X to push the upper handle 2 of the power converter 5 to rotate the power converter 5, and the first direction X is the arrangement direction of the power converter 5 and the supporting assembly 1. In this embodiment, the third fastener 71 is threadedly connected to the supporting assembly 1, which can be a stud, a screw, a bolt or other threaded structure, and the third fastener 71 abuts against the end surface of the upper handle 2.

[0071] In an implementation, the support assembly 1 comprises two spaced-apart body portions 11, each of which is provided with a mounting hole 116 extending along the second direction Y, and the third fastener 71 is arranged along the first direction X through the mounting hole 116 and the adapter portion 14 and is threadedly connected with the adapter portion 14. In the case of lifting movement of the adapter portion 14, the mounting hole 116 provides space for movement of the third fastener 71. The upper handle 2 has a groove bottom surface opposite the groove. In the second direction Y, the vertical distance between the third fastener 71 and the groove is less than the vertical distance between the third fastener 71 and the groove bottom surface.

[0072] The side plates 140 of the adapter portion 14 are provided in a plurality of numbers and are arranged around the outer periphery of the second top plate 143. Two side plates 140 that are oppositely arranged along the first direction X are provided, one of which is a first side plate 141, and the other is a second side plate 142. The first side plate 141 is provided with a second avoiding hole 1411 extending along the first direction X. A portion of the upper handle 2 is arranged through the second avoiding hole 1411. The first side plate 141 is inserted into the clamping groove 21 at a portion corresponding to the lower edge of the second avoiding hole 1411, so that the upper handle 2 is hung on the first side plate 141. The third fastener 71 is threadedly connected to the second side plate 142. The first avoiding hole 1174, the second avoiding hole 1411, the third fastener 71, and the mounting hole 116 are oppositely arranged along the first direction X. The third fastener 71 is in abutment with the end surface of the upper handle 2. Since the groove width of the clamping groove 21 is greater than the thickness of the first side plate 141, the abutment position of the upper handle 2 with the first side plate 141 corresponds to a fulcrum, forming a lever structure. Therefore, when the third fastener 71 exerts a pushing force on the end surface of the upper handle 2, the upper handle 2 can be rotated. The adapter portion 14 simultaneously serves as a hanging carrier of the upper handle 2 and a setting carrier of the third fastener 71, so that the degree of integration of the structure is increased, and the required installation space is reduced.

[0073] In another implementation, the structure of the body portion 11 comprises a plate member 1100, a first bending section 1101, and a second bending section 1102. The adapter portion 14 is arranged between the two first bending sections 1101. The adjusting bolt 15 is arranged along the second direction Y through the second bending section 1102 and is threadedly connected with the second bending section 1102. The side wall of the plate member 1100 is provided with an avoiding window extending along the second direction Y. The third fastener 71 is arranged through the avoiding window and the adapter portion 14 and is threadedly connected with the adapter portion 14. Since the two first bending sections 1101 are spaced apart, a channel with an opening is formed, which can directly move the upper handle 2 and the adapter portion 14, reducing the number of required avoiding structures and simplifying the structure design.

[0074] According to a second aspect of the present disclosure, there is provided an electrical system comprising a power converter 5 and the wall-mounted device as described above, the power converter 5 is arranged on the wall-mounted device and is capable of at least one of a first action and a second action through the wall-mounted device, wherein the first action is that the power converter 5 is capable of rotating around a support point of the upper handle 2, and the second action is that the power converter 5 is capable of lifting and moving.

[0075] Please refer to Figure 1 In some embodiments, the power converter 5 has the upper handle 2 and the lower handle 4, and there is a spacing between the power converter 5 and the support assembly 1 to increase the contact area of the power converter 5 with air and facilitate heat dissipation.

[0076] The lower handle 4 functions to locally extend the power converter 5, and in the case that the power converter 5 and the support assembly 1 are in the same spacing, the lower handle 4 can make the power converter 5 closer to the adjusting part 32, thereby shortening the movement distance of the adjusting part 32. Furthermore, the lower handle 4 is spaced between the power converter 5 and the adjusting part 32, which avoids the adjusting part 32 directly applying a force to the power converter 5, thereby protecting the power converter 5. In addition, since the lower handle 4 and the upper handle 2 are spaced, the force arm between the adjusting part 32 and the upper handle 2 is increased, which helps to reduce the resistance that the adjusting part 32 receives when pushing the lower handle 4.

[0077] In the description of the present application, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0078] The embodiments, implementation manners and related technical features of the present application can be combined or replaced with each other without conflict.

[0079] The above is only the preferred embodiment of the present application, and does not limit the present application in any form, but any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application, which does not deviate from the technical solution content of the present application, still belongs to the scope of the technical solution of the present application.
