Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] In order to enable those skilled in the art in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0042] The purpose of the present invention is to provide a wall - hanging device that can fix the position of an inverter while meeting the requirements of hanging and installing the inverter.

[0043] Please refer to Figures 1 to 5 , to achieve the above - mentioned purpose, the present invention provides a wall - hanging device for hanging an inverter 100 on a wall, including a first hanging bracket 200 and a second hanging bracket 300.

[0044] The first hanging bracket 200 includes a suspension part 210 and connection parts 220 connected to both ends of the suspension part 210. The connection parts 220 are detachably connected to the radiator 110 of the inverter 100, so as to form a first gap between the suspension part 210 and the radiator 110.

[0045] The radiator 110 includes a plurality of first fins, and the connecting portion 220 can be connected to the first fins to achieve a detachable connection between the first bracket 200 and the radiator 110 .

[0046] It can be understood that the connecting portion 220 is a bent structure bent toward one side of the hanging portion 210. For example, the connecting portion 220 and the hanging portion 210 as a whole adopt a U-shaped structure, which is connected to the radiator 110 of the inverter 100 through the bending structure, so that a first gap is formed between the hanging portion 210 and the radiator 110.

[0047] The radiator 110 may be provided with a first threaded hole, and the connecting portion 220 may be provided with a second threaded hole corresponding to the first threaded hole. The bolts may be used to connect the connecting portion 220 and the radiator 110, and facilitate subsequent disassembly and replacement of the first bracket 200.

[0048] The second bracket 300 includes a fixing plate 310 fixed to the wall on one side, a hanging plate 320 connected to the top of the fixing plate 310 and spaced apart from the wall, and a hanging ear 330 movably connected to the fixing plate 310. The hanging plate 320 is passed through the first gap to connect the first bracket 200 and the second bracket 300. The hanging ear 330 is located on the side of the fixing plate 310 facing away from the wall, and one end of the hanging ear 330 can extend out of the fixing plate 310 to be connected to the inverter 100.

[0049] In some embodiments, the inverter 100 also includes an inductor box disposed outside its chassis, which is also provided with a second fin for heat dissipation. The connection between the end of the hanging ear 330 extending outside the fixing plate 310 and the second fin also has the effect of locking the inverter 100 as a whole.

[0050] In addition, one end of the hanging ear 330 extending out of the fixing plate 310 may also be connected to a heat dissipation fin on the heat sink 110 in the inverter 100 , and the heat dissipation fin is the first fin mentioned above.

[0051] The width of the first gap in the length direction of the fixed plate 310 is obtained by the distance between the two connecting parts 220. At the same time, according to the assembly requirements, the width of the hanging plate 320 in the length direction of the fixed plate 310 is set so that the hanging plate 320 can be inserted into the first gap and the first hanger 200 can be prevented from shaking left and right due to excessive remaining space after the hanging plate 320 is installed in the first gap.

[0052] In some embodiments, slides may be provided on one side of the two connecting portions 220 facing each other, and pulleys adapted to the slides may be provided at both ends of the hanging plate 320 to facilitate the vertical movement of the hanging plate 320 relative to the first hanging bracket 200. Among them, an elastic member may be provided at the bottom of the slide, and the pulley is limited to a certain extent by the restoration after the elastic member contacts the pulley. At the same time, this restoration process is reversible, that is, when the first hanging bracket 200 is moved in the opposite direction, the elastic member can be compressed by the pulley for the pulley to escape, and then the elastic member returns to its natural state again.

[0053] The first hanging bracket 200 is connected through the connecting portion 220 of the first hanging bracket 200 and the radiator 110 of the inverter 100, and the fixing plate 310 of the second hanging bracket 300 is connected to the wall. The hanging plate 320 of the second hanging bracket 300 can be inserted between the hanging portion 210 of the first hanging bracket 200 and the radiator 110 to form a first gap, so that the first hanging bracket 200 and the second hanging bracket 300 are connected. At the same time, the hanging ear 330 that can move relative to the fixing plate 310 extends out of the fixing plate 310 and is connected and locked with the inverter 100 to meet the requirements of hanging and installing the inverter 100 while being able to fix the position of the inverter 100, thereby avoiding the movement, collision, etc. of the inverter 100 and improving the service life of the inverter 100.

[0054] It should be noted that the hanging ear 330 is connected to the fixing plate 310 through the bracket 400. The bracket 400 includes a first plate body 410 and a second plate body 420. The first plate body 410 is connected to one end of the fixing plate 310; the second plate body 420 is connected to the side of the first plate body 410 facing away from the fixing plate 310, and the second plate body 420 is parallel to the fixing plate 310. The first plate body 410 sets the second plate body 420 at an interval from the fixing plate 310 to facilitate providing the required space for the subsequent movement of the hanging ear 330.

[0055] The hanging ear 330 includes a moving plate 331 and a positioning plate 332. The moving plate 331 is attached to the side of the second plate body 420 facing away from the first plate body 410; the positioning plate 332 is connected to one end of the moving plate 331. A first positioning hole is provided on the inverter 100, and a second positioning hole 333 corresponding to the first positioning hole is provided on the positioning plate 332. The fixing member 500 is inserted through the first positioning hole and the second positioning hole 333 to limit the relative movement between the positioning plate 332 and the inverter 100.

[0056] It should be noted that the hanging ear 330 in the present application moves relative to the bracket 400 and has a large movement range to be applicable to various types and sizes of the inverter 100. According to the position of the first positioning hole on the inverter 100, the moving plate 331 of the hanging ear 330 can be adaptively moved to the corresponding position, thereby realizing the connection and fixation between the hanging ear 330 and the inverter 100, and achieving the effect of preventing the inverter 100 from being stolen.

[0057] By attaching the moving plate 331 to the second plate body 420, direct contact between the moving plate 331 and the fixed plate 310 during the movement of the moving plate 331 is avoided, increasing the moving space of the moving plate 331. The moving plate 331 is used to drive the positioning plate 332 connected to one end thereof to extend out of the fixed plate 310 and can be moved to a preset position according to actual needs. Through the connection between the positioning plate 332 and the inverter 100 after extension, mutual locking of the first hanger 200, the second hanger 300, and the inverter 100 is achieved.

[0058] Both the first positioning holes and the second positioning holes 333 are two or more. The first positioning holes can be provided on the first fins of the radiator 110 in the inverter 100 or on the second fins of the inductor box, or can be provided on other external structures of the inverter 100 according to actual needs. The fixing member 500 is a screw and / or a locking member. For example, the first positioning holes and the second positioning holes 333 include a pair of corresponding threaded holes and a pair of corresponding through holes. The corresponding connection of the threaded holes in the first positioning holes and the second positioning holes 333 can be achieved through a screw, and the corresponding connection of the through holes in the first positioning holes and the second positioning holes 333 can be achieved through a locking member. Among them, the locking member includes a penetrating portion with a diameter smaller than the diameters of the first positioning holes and the second positioning holes 333.

[0059] It should be noted that the locking member is also applicable to the fixed connection between two threaded holes, as long as the penetrating portion in the locking member can penetrate into and out of the threaded hole.

[0060] In this embodiment, two spaced-apart first through holes 421 are provided on the second plate body 420; a strip-shaped second through hole 334 is provided on the moving plate 331, and the length direction of the second through hole 334 is the same as the connection direction of the two first through holes 421. The positioning member 600 is inserted through the first through hole 421 and the second through hole 334 so that the moving plate 331 can move relative to the second plate body 420 along the length direction of the second through hole 334.

[0061] The positioning member 600 is specifically a mother-daughter screw. Through the mother-daughter screw, the second plate body 420 and the moving plate 331 can be limited. At the same time, by setting the second through hole 334 on the moving plate 331 as strip-shaped, it is convenient for the mother-daughter screw to slide relative to the second through hole 334 along the length direction of the second through hole 334, thereby realizing the movement of the moving plate 331 relative to the second plate body 420, so that the positioning plate 332 extends to the preset position. The positioning member 600 can also be selected according to actual needs as long as the above relative sliding process can be achieved.

[0062] Among them, the two first through holes 421 are arranged at the same height to ensure that the movable plate 331 provided with the strip-shaped second through hole 334 can move horizontally; the length direction of the second through hole 334 is consistent with the length direction of the fixed plate 310, and the length of the second through hole 334 determines the length of the hanging ear 330 extending outward. When the second positioning hole 333 is close to the fixed plate 310, the hanging ear 330 only needs to be slightly extended. When the second positioning hole 333 is far from the fixed plate 310, the hanging ear 330 needs to be extended a longer distance to ensure that the screw and / or the lock can be locked.

[0063] In some embodiments, the hanging ear 330 may also adopt a telescopic rod that can be extended and retracted, and the fixed end of the telescopic rod is fixed to the bracket 400 or the fixed plate 310. The purpose of controlling the extension distance of the telescopic rod is achieved by pulling the movable end of the telescopic rod, so as to complete the subsequent fixation of the movable end of the telescopic rod and the inverter 100.

[0064] In addition, the fixed plate 310 is a U-shaped structure including two horizontal plates 311 and one vertical plate 312, the hanging plate 320 is connected to a horizontal plate 311, the vertical plate 312 is connected to the wall, and the end of the movable plate 331 facing away from the positioning plate 332 is located in the U-shaped groove formed by the horizontal plate 311 and the vertical plate 312.

[0065] The vertical plate 312 is attached to the wall so that the side of the vertical plate 312 facing away from the wall and the sides of the two horizontal plates 311 facing each other together form a U-shaped groove with a certain accommodating space, through which the hanging ear 330 can be stored before use and extended during use.

[0066] A contact plate is provided on the side of a horizontal plate 311 far from the hanging plate 320 away from the hanging plate 320, through which a larger contact area with the inverter 100 is provided to reduce the pressure on the second hanging bracket 300 after the inverter 100 is installed.

[0067] A plurality of third through holes 313 are formed on the vertical plate 312 , and the connecting members are passed through the third through holes 313 to fix the vertical plate 312 to the wall.

[0068] It should be noted that the connecting pieces are specifically expansion screws, and the number and type of the connecting pieces can be adjusted according to actual needs as long as the above-mentioned purpose can be achieved.

[0069] In this embodiment, the first plate body 410 and the second plate body 420 are perpendicular to each other, and the distance between the second plate body 420 and the vertical plate 312 is greater than the distance between the end of the connecting member facing away from the wall and the vertical plate 312, so as to avoid the restriction of the connecting member on the movement process of the hanging ear 330 and increase the movement space of the hanging ear 330.

[0070] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0071] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0072] Specific examples are used in this article to elaborate on the principles and implementation manners of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the present utility model.
