The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figures 2 to 7 , which is the first embodiment of the present utility model, provides an outer cover for a frequency conversion component. The outer cover for the frequency conversion component includes a protective component 200, a fixing component 300 and a main body component 100. The three can cooperate to adjust the angle of the control panel and protect the control panel.

[0031] The protective assembly 200 includes a protective part 201, including a protective plate 201a, a rotating column 201b, a ring gear 201c, a coil spring 201d and a limit block 201e. The rotating column 201b is inserted into the bottom of the protective plate 201a, the ring gear 201c is located at one end of the rotating column 201b, the coil spring 201d is fixed to the inner wall of the ring gear 201c, and the limit block 201e is located at one end of the protective plate 201a.

[0032] The setting of the protective plate 201a can protect the operation panel 102 to prevent the operation panel 102 from being accidentally hit by the control panel, causing damage to its surface, malfunction of the buttons or cracks in the display screen. When the operation panel 102 is closed, a torsional force can be applied to the coil spring 201d. When the operation panel 102 needs to be used, the rebound of the coil spring 201d will drive the ring gear 201c to rotate. The ring gear 201c is rotatably connected to the inner wall of the frequency converter 101 through a bearing. The rotation of the ring gear 201c will drive the rotating column 201b to rotate. The rotation of the rotating column 201b can drive the protective plate 201a to rotate and open it. When closing the protective plate 201a, in order to prevent the rebound of the coil spring 201d from driving the protective plate 201a to open automatically, the setting of the limit block 201e can limit the protective plate 201a to prevent the protective plate 201a from opening automatically.

[0033] The fixing assembly 300 is arranged below the protective plate 201a and includes a fixing part 301, including a movable column 301a, a limit plate 301b, a tooth frame 301c, a hinged rod 301d and a first spring 301e. The movable column 301a is located below the protective plate 201a, the limit plate 301b is fixed to one end of the movable column 301a, the tooth frame 301c is sleeved on the outside of the limit plate 301b, the tooth frame 301c and the limit plate 301b are movably connected, the hinged rod 301d is arranged on one side of the tooth frame 301c, and the first spring 301e is located on one side of the hinged rod 301d.

[0034] When the operating panel 102 needs to be flipped, the movable column 301a is rotated. The movable column 301a is plugged into one side of the operating panel 102 and the frequency converter box 101. The movable column 301a is rotatably connected to the frequency converter box 101 through a rotating shaft. The rotation of the movable column 301a drives the limit plate 301b to rotate, and the rotation of the movable column 301a can make the operating panel 102 flip over. When the operating panel 102 flips over, it drives the hinged rod 301d to move. The movement of the hinged rod 301d can apply a squeezing force to the first spring 301e. At this time, in order to prevent the rebound force of the first spring 301e from driving the operating panel 102 to return to its original position, the limit plate 301b can be limited in one direction by the setting of the tooth frame 301c to prevent the limit plate 301b from reversing, thereby preventing the operating panel 102 from returning to its original position.

[0035] Example 2

[0036] Reference Figures 2 to 7 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0037] Specifically, the protection assembly 200 further includes a movable part 202, which is disposed on the ring gear 201c. A gear 202a is disposed on one side of the ring gear 201c, and the gear 202a and the ring gear 201c are engaged. A positioning column 202b is fixed to one side of the coil spring 201d.

[0038] Gear 202a is fixed to one end of the rotating column 201b. When the rotating column 201b rotates, it drives the gear 202a to rotate. The rotation of the gear 202a drives the ring gear 201c to rotate. The rotation of the ring gear 201c can apply a torsional force to the coil spring 201d. The positioning column 202b is fixed to the inner wall of the frequency converter box 101. The setting of the positioning column 202b can support the coil spring 201d to prevent the coil spring 201d from deflecting.

[0039] Specifically, a limiting frame 202c is sleeved on the outer side of the limiting block 201e, a positioning rod 202d is fixed to one side of the limiting block 201e, a supporting frame 202e is sleeved on the outer side of the positioning rod 202d, and the positioning rod 202d and the supporting frame 202e are movably connected.

[0040] A limiting groove corresponding to the limiting block 201e is provided in the limiting frame 202c, and the limiting block 201e is set as an inclined surface. By engaging the limiting block 201e with the limiting groove, the protective plate 201a can be limited. When it is necessary to release the limitation of the protective plate 201a, the positioning rod 202d is moved, and the positioning rod 202d drives the limiting block 201e to separate from the limiting groove, thereby releasing the limitation of the protective plate 201a. The support frame 202e is fixed to one side of the protective plate 201a. The positioning rod 202d can be supported by the setting of the support frame 202e to prevent the positioning rod 202d from offset.

[0041] Specifically, a support sleeve 202f is sleeved on the outer side of the positioning rod 202d, and the support sleeve 202f is movably connected to the positioning rod 202d. A second spring 202g is fixed to the inner wall of the support sleeve 202f, and a dial plate 202h is sleeved on the outer side of the positioning rod 202d.

[0042] The support sleeve 202f is fixed to the inner wall of the support frame 202e. When the positioning rod 202d moves and drives the limit block 201e to separate from the limit groove, the positioning rod 202d will move in the support sleeve 202f. The second spring 202g is fixed to one end of the positioning rod 202d. The movement of the positioning rod 202d can apply an extrusion force to the second spring 202g. When the positioning rod 202d is released, the rebound force of the second spring 202g will drive the limit block 201e to return to its original position for next use. The positioning rod 202d can be driven to move by moving the dial plate 202h.

[0043] Specifically, the fixing assembly 300 further includes a moving member 302, which is disposed on the limiting plate 301b. A clamping block 302a is disposed in the limiting plate 301b, and the clamping block 302a is hinged to the limiting plate 301b.

[0044] The tooth frame 301c is fixed to one side of the frequency converter box 101, and a positioning groove corresponding to the block 302a is opened in the tooth frame 301c. The block 302a is set to an inclined surface. When the operating panel 102 is flipped, the operating panel 102 drives the limit plate 301b to rotate, and the limit plate 301b drives the block 302a to move. At this time, the positioning groove can squeeze the block 302a to separate the block 302a from the positioning groove. When the block 302a moves to the next positioning groove, the block 302a will engage with the positioning groove. When the operating panel 102 is reversed, the positioning groove on the tooth frame 301c can limit the block 302a in one direction, thereby preventing the limit plate 301b from reversing, and further preventing the operating panel 102 from reversing.

[0045] Specifically, a torsion spring 302b is fixed to one side of the clamping block 302a, and the torsion spring 302b is fixed to the inner wall of the limiting plate 301b. A shift bar 302c is fixed to one side of the clamping block 302a.

[0046] When the block 302a moves and separates from the positioning slot, a twisting force can be applied to the torsion spring 302b. When the block 302a moves to the next positioning slot, the rotational force of the torsion spring 302b can drive the block 302a to engage with the positioning slot. When the operating panel 102 needs to be returned to its original position, the block 302a can be separated from the positioning slot by moving the shift bar 302c, thereby allowing the operating panel 102 to return to its original position.

[0047] Specifically, a movable rod 302d is provided on one side of the hinged rod 301d. The movable rod 302d and one side of the hinged rod 301d are rotatably connected through a rotating shaft. A moving block 302e is provided on one end of the movable rod 302d. The moving block 302e and the movable rod 302d are hinged.

[0048] When the operating panel 102 flips, the movable rod 302d will move, and the movement of the movable rod 302d will drive the moving block 302e to move. The movement of the moving block 302e can drive the hinged rod 301d to move, and the movement of the hinged rod 301d can support the operating panel 102 to prevent the operating panel 102 from deflecting during movement.

[0049] Example 3

[0050] Reference Figures 1 to 7 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0051] Specifically, a support column 302f is inserted into the moving block 302e, and the support column 302f is movably connected to the moving block 302e. A positioning plate 302g is fixed to one end of the support column 302f.

[0052] A first spring 301e is fixed on one side of the moving block 302e, and the first spring 301e is fixed to one side of the positioning plate 302g. The positioning plate 302g is fixed to the inner wall of the frequency converter box 101. When the moving block 302e moves, it will move on the support column 302f. When the moving block 302e moves, it can apply an extruding force to the first spring 301e. When the operating panel 102 needs to return to its original position, the rebound of the first spring 301e can drive the moving block 302e to return to its original position, thereby allowing the operating panel 102 to return to its original position. The positioning plate 302g is used to support the support column 302f to prevent the support column 302f from deflecting.

[0053] Specifically, it also includes a main body component 100, which is arranged on the hinge rod 301d, including a frequency conversion box 101 and an operating panel 102. The operating panel 102 is hinged to one end of the hinge rod 301d, and the frequency conversion box 101 is sleeved on the outside of the operating panel 102.

[0054] The frequency conversion box 101 can provide physical protection for the frequency conversion component to prevent it from being affected by the external environment, such as dust, moisture, impact, etc., which helps to improve the reliability and stability of the frequency conversion component. The operation panel 102 is provided with start and stop buttons to facilitate users to operate the frequency conversion component.

[0055] Specifically, a heat dissipation frame 103 is provided on one side of the frequency converter box 101 .

[0056] During operation of the frequency converter box 101 , the electronic components inside will generate a large amount of heat. The heat dissipation frame 103 can dissipate heat inside the frequency converter box 101 .

[0057] When in use, first move the dial plate 202h to drive the positioning rod 202d to move, and the positioning rod 202d will move in the support sleeve 202f. The movement of the positioning rod 202d can apply a squeezing force to the second spring 202g. The movement of the positioning rod 202d drives the limit block 201e to separate from the limit groove. At this time, the limit on the protective plate 201a can be released, and then the rebound of the coil spring 201d drives the ring gear 201c to rotate. The rotation of the ring gear 201c drives the gear 202a to rotate, and the rotation of the gear 202a drives the rotating column 201b to rotate. The rotation of the rotating column 201b can drive the operating plate 102 to reverse, so that the operating plate 102 can be raised, which is convenient for its operation.

[0058] By rotating the limit plate 301b, the limit plate 301b rotates and drives the card block 302a to move. At this time, the positioning groove can squeeze the card block 302a, so that the card block 302a is separated from the positioning groove. When the card block 302a moves and separates from the positioning groove, a torsional force can be applied to the torsion spring 302b. When the card block 302a moves to the next positioning groove, the rotation force of the torsion spring 302b can drive the card block 302a to engage with the positioning groove. The rotation of the limit plate 301b drives the movable column 301a to rotate at the same time. The rotation of the movable column 301a can make the operating panel 102 rise, and when the operating panel 102 rises, it drives the movable rod 302d to move The movement of the movable rod 302d will drive the moving block 302e to move, and the movement of the moving block 302e can drive the hinged rod 301d to move. The movement of the hinged rod 301d can support the operating panel 102 to prevent the operating panel 102 from deviating during movement, and the moving block 302e can apply a squeezing force to the first spring 301e when it moves. When the operating panel 102 needs to return to its original position, the block 302a is separated from the positioning slot by shifting the shift bar 302c, and then the moving block 302e can be driven to return to its original position by the rebound of the first spring 301e, thereby allowing the operating panel 102 to return to its original position.
