[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3This utility model provides an embodiment of a modular FFU device that is easy to disassemble, including a mounting frame 1. A lifting mechanism 2 is provided at the top of the mounting frame 1. A mounting plate 3 is provided on the inner side wall of the mounting frame 1. There are two sets of mounting plates 3. The lower set of mounting plates 3 is fixed to the inner wall at the bottom of the mounting frame 1. The upper set of mounting plates 3 can slide on the inner side of the mounting frame 1, thereby lowering the mounting plate 3 to facilitate maintenance of the upper set of mounting plates 3. A fan module 5 is detachably mounted on the surface of the mounting plate 3 through a quick-release assembly 6. The surface of the mounting plate 3 has a mounting groove. The rear end of the fan module 5 is inserted into the inner wall of the mounting groove. The contact between the two allows for positioning and installation of the fan module 5. Furthermore, a slot is provided on the outer side of each set of fan modules 5 to facilitate the insertion of wiring harnesses.

[0034] Reference Figure 2 , Figure 4 The quick-release assembly 6 includes a handle 61, which is slidably connected to the surface of the bottom end of the fan module 5. Two sets of hinge rods a62 are hinged to the outer sidewall of the handle 61. A connecting seat 63 is hinged to the end of each hinge rod a62 away from the handle 61. A groove is formed on the surface of the handle 61. Pulling the handle 61 downwards synchronously lowers the hinge rods a62, thereby pulling the corresponding connecting seat 63 outwards along the inner wall of the fan module 5. The hinges of the hinge rods a62, handle 61, and connecting seat 63 are inclined. The connecting seat 63 is slidably connected to the inner sidewall of the fan module 5. Two sets of hinge rods b64 are hinged to the inner sidewall of the connecting seat 63. The ends of the two sets of hinge rods b64 away from the connecting seat 63 are hinged... With wedge 65, when the connecting seat 63 moves outward under the pull of the hinge rod a62, it will also drive the two sets of hinge rods b64 to move synchronously, so that the two sets of hinge rods b64 pull the corresponding wedge 65 to move closer or further apart. The wedge 65 is slidably connected to the inner wall of the rear end of the fan module 5. The side wall of the mounting groove of the mounting plate 3 is provided with a slot. The outer wall of the wedge 65 is engaged with the inner wall of the slot. The engagement between the two can fix the fan module 5 on the surface of the mounting plate 3. The two sets of wedges 65 are elastically connected by a return spring 66. By setting the return spring 66 between the two sets of wedges 65, the position of the two sets of wedges 65 after being pulled by the hinge rod b64 can be quickly reset.

[0035] Reference Figure 2 , Figure 3 and Figure 5The lifting mechanism 2 includes a fixed frame 21, a support frame 23 is fixedly connected to the top of the outer wall of the fixed frame 21, the fixed frame 21 is fixedly connected to the top of the outer wall of the mounting frame 1, a winding shaft 24 is rotatably connected to the inner side wall of the support frame 23, a servo motor 26 is fixedly connected to the outer side wall of the support frame 23, the output shaft of the servo motor 26 is fixedly connected to the winding shaft 24, and a steel wire rope 25 is wound around the surface of the winding shaft 24. Driven by the servo motor 26, the winding shaft 24 can be rotated, thereby driving the steel wire rope 25 to be wound and unwound on its surface.

[0036] Reference Figure 2 and Figure 5 The upper surface of the fixed frame 21 has a groove, through which the wire rope 25 passes and is slidably connected to the inner wall of the groove. The groove of the fixed frame 21 matches the width of the winding shaft 24, thereby guiding the wire rope 25. A connecting plate 27 is hinged to the bottom end of the outer wall of the wire rope 25. When the wire rope 25 is wound and unwound, it pulls the connecting plate 27 to slide up and down on the inner side wall of the fixed frame 21 and the mounting frame 1. Two sets of inserts 28 are fixedly connected to the bottom end of the outer wall of the connecting plate 27. The surface of the inserts 28 contacts the inner side wall of the U-shaped seat 22. The contact between the two sets of inserts 28 allows them to hook onto the inner side wall of the U-shaped seat 22, thereby driving the mounting plate 3 at the bottom of the U-shaped seat 22 to rise and fall. An L-shaped guide groove 29 is provided on the inner side wall of the mounting frame 1. The slider 4 is slidably connected to the inner side wall of the L-shaped guide groove 29. The L-shaped guide groove 29 is L-shaped, and an electric slide rail is provided in the upper horizontal groove. The vertical groove can only guide the slider 4. When the fan module 5 at the upper mounting plate 3 is being repaired, the slider 4 can be pushed to move inside it by the electric slide rail in the horizontal groove of the L-shaped guide groove 29. After the movement, the empty groove formed by the U-shaped seat 22 and the mounting plate 3 will be inserted into the surface of the insert block 28. At this time, the unwinding is achieved by rotating the winding shaft 24, so that the sliders 4 on both sides of the upper mounting plate 3 can move in the vertical groove of the L-shaped guide groove 29, thereby lowering the whole structure and facilitating its repair. The mounting plate 3 is provided with two sets. The outer wall of the top of the upper mounting plate 3 is fixedly connected to the U-shaped seat 22, and the outer side wall of the upper mounting plate 3 is fixedly connected to two sets of sliders 4.

[0037] Working principle: When it is necessary to disassemble the fan module 5, the operator pulls the handle 61. The handle 61 slides on the bottom surface of the fan module 5. Since the handle 61 and the hinge rod a62 are inclinedly hinged, when the handle 61 is pulled down, it drives the hinge rod a62 to descend synchronously, thereby pulling the connecting seat 63 to move outward on the inner wall of the fan module 5. The connecting seat 63 then drives the wedge block 65 to move through the hinge rod b64. The linkage of the two sets of hinge rods b64 causes the wedge block 65 to move towards each other. At this time, the outer wall of the wedge block 65 disengages from the slot on the side wall of the mounting groove of the mounting plate 3, thereby removing the fan module 5 from the mounting plate 3 as a whole. The return spring 66 between the two sets of wedge blocks 65 can make the wedge block 65 quickly return to its original position, which is convenient for the next installation operation. The operation is reversed during installation.

[0038] The L-shaped guide groove 29 on the inner sidewall of the mounting frame 1 works in conjunction with the slider 4. The upper horizontal groove of the L-shaped guide groove 29 is equipped with an electric slide rail, and the vertical groove is used for guidance. During maintenance, the slider 4 is first moved by the electric slide rail in the horizontal groove of the L-shaped guide groove 29, so that the empty groove formed by the U-shaped seat 22 and the mounting plate 3 is inserted into the outer wall of the insert block 28 at the bottom of the connecting plate 27. Then, the winding shaft 24 rotates to unwind, and the wire rope 25 drives the connecting plate 27 to descend, which also drives the upper mounting plate 3 to descend. The sliders 4 on both sides slide in the vertical groove of the L-shaped guide groove 29 to ensure that the mounting plate 3 moves down smoothly, which makes it convenient for staff to inspect and maintain the fan module 5 on the mounting plate 3. Throughout the process, the various components of the device work closely together to realize the function of easy disassembly and maintenance of the modular FFU device, effectively improving the convenience and efficiency of equipment maintenance.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
