[0036] The utility model provides a fixing device 10 , which is intended to simultaneously meet the high maintenance requirements of a controller 20 and a plurality of drive boards 30 .

[0037] Combined with reference Figures 1 to 7 In one embodiment of the fixing device 10 of the utility model, the fixing device 10 is used to install the controller 20 and the drive board 30; the fixing device 10 includes an inverter unit 11 and a mounting plate 12; the inverter unit 11 has a front mounting space 111; the mounting plate 12 has a front panel surface 12, one of the front mounting space 111 and the front panel surface 12 is used to install the controller 20, and the other is used to install the drive board 30; the mounting plate 12 is movably arranged in the front mounting space 111, and has a first position and a second position; wherein, when the mounting plate 12 is in the first position, the mounting plate 12 blocks the front mounting space 111, so that the controller 20 or the drive board 30 installed on the front panel surface 12 is exposed in front of the inverter unit 11; when the mounting plate 12 is in the second position, the mounting plate 12 opens the front mounting space 111, so that the controller 20 or the drive board 30 installed in the front mounting space 111 is exposed in front of the inverter unit 11.

[0038] It can be understood that in the fixing device 10 proposed by the utility model, a movable mounting plate 12 is provided in the front mounting space 111 of the inverter unit 11, the front panel surface 12 of the mounting plate 12 is the first layer, and the front mounting space 111 of the inverter unit 11 is the second layer, which is equivalent to adopting a double-layer structure arrangement, and one of the front mounting space 111 of the inverter unit 11 and the front panel surface 12 of the mounting plate 12 can be used to install the controller 20, and the other one can be used to install the drive board 30. For example, when the controller 20 is mounted on the front panel 12 of the mounting plate 12, and the driver board 30 is mounted in the front mounting space 111 of the inverter unit 11, when the controller 20 needs to be operated, maintained, inspected, or burned, the mounting plate 12 moves to the first position, and the mounting plate 12 can block the front mounting space 111, so that the controller 20 mounted on the front panel 12 is exposed in front of the inverter unit 11, and the controller 20 can be directly operated from the front; and when the driver board 30 needs to be maintained, replaced, inspected for faults, or burned, the mounting plate 12 moves to the second position, and the mounting plate 12 can open the front mounting space 111, so that the driver board 30 mounted on the front mounting space 111 is exposed in front of the inverter unit 11, and the driver board 30 can be directly operated from the front. In this way, the high maintenance requirements of the controller 20 and multiple driver boards 30 can be met at the same time.

[0039] In addition, by installing the controller 20 and the drive board 30 on the double-layer structure formed by the front installation space 111 and the front panel surface 12, the communication cable between the controller 20 and the drive board 30 can be shortened and simplified, greatly reducing the problems of low reliability such as interference from strong electricity, magnetic field signals generated by EMC (electromagnetic compatibility), and easy failure of the communication cable.

[0040] In this embodiment, the drive board 30 can be electrically connected to the inverter unit 11 by using a communication cable, and the controller 20 can also be electrically connected to the drive board 30 and the external device by using a communication cable. Among them, the drive board 30 can be provided with one or more pieces. When there are multiple drive boards 30, the multiple drive boards 30 can be distributed in an array in the front installation space 111 of the inverter unit 11 or on the front panel 12 of the installation board 12.

[0041] In actual application, the controller 20 can be fixedly connected to the front installation space 111 or the front panel 12 by screw connection, clamping, bonding, etc. Similarly, the drive board 30 can also be fixedly connected to the front installation space 111 or the front panel 12 by screw connection, clamping, bonding, etc.

[0042] In actual application, the mounting plate 12 can be movably connected to the front mounting space 111 of the inverter unit 11 by sliding, rotating, etc., so as to switch between the first position and the second position. When the mounting plate 12 is movably connected to the front mounting space 111 of the inverter unit 11 by rotating, the mounting plate 12 can also be rotatably connected to the front mounting space 111 of the inverter unit 11 by flipping, plane rotation, etc.

[0043] In one embodiment, a slide rail may be provided in the front installation space 111 of the inverter unit 11, and a slider may be provided on the mounting plate 12. With the cooperation of the slide rail and the slider, the mounting plate 12 may slide to switch between the first position and the second position.

[0044] In another embodiment, a rotating shaft may be provided in the front installation space 111 of the inverter unit 11, and the rotating shaft may extend along the direction of the front installation space 111 of the inverter unit 11. An axial hole may be provided on the side of the mounting plate 12 facing away from the front plate surface 12, and the mounting plate 12 may be rotated along the plane where the front installation space 111 is located by cooperation between the rotating shaft and the axial hole to switch between the first position and the second position.

[0045] In another embodiment, one side of the mounting plate 12 can also be rotatably connected to the front mounting space 111 of the inverter unit 11, so that the mounting plate 12 can be flipped relative to the front mounting space 111 of the inverter unit 11 to switch between the first position and the second position.

[0046] Optionally, see Figures 1 to 7 In one embodiment of the fixing device 10 of the present invention, the mounting plate 12 is flippably disposed in the front mounting space 111 to switch between the first position and the second position.

[0047] Since the fixing device 10 is usually installed in the converter box and is limited by the internal space of the box, if sliding, planar rotation or the like is used to realize the movement of the mounting plate 12, the internal space of the box will affect the movement range of the mounting plate 12. Therefore, by making the mounting plate 12 flippably arranged in the front mounting space 111 of the inverter unit 11, the movement of the mounting plate 12 is not limited by the internal space of the box, thereby ensuring that the mounting plate 12 has a sufficient range of movement and can smoothly switch between the first position and the second position.

[0048] In some embodiments, in order to facilitate flipping of the mounting plate 12 , a handle may be provided on the front panel 12 of the mounting plate 12 , and the user may flip the mounting plate 12 by the handle.

[0049] Optionally, see Figures 1 to 7In one embodiment of the fixing device 10 of the present invention, the fixing device 10 further includes a hinge structure 13 , and the mounting plate 12 is rotatably connected to the front mounting space 111 via the hinge structure 13 .

[0050] Such arrangement enables the mounting plate 12 to be more smoothly flipped between the first position and the second position under the rotation connection of the hinge structure 13 .

[0051] In actual application, the hinge structure 13 can be specifically arranged on the top side of the mounting plate 12 , or on the bottom side or the left and right sides of the mounting plate 12 .

[0052] Optionally, see Figures 1 to 7 In one embodiment of the fixing device 10 of the present invention, the hinge structure 13 is disposed on the top side of the mounting plate 12 .

[0053] With such arrangement, when the user turns over the mounting plate 12 , the user can use the method of turning up and pressing down to realize the turning of the mounting plate 12 , which makes it more convenient for the user to turn over the mounting plate 12 .

[0054] Optionally, see Figures 1 to 6 In one embodiment of the fixing device 10 of the present invention, the controller 20 is used to be installed on the front panel 12 , and the driving board 30 is used to be installed in the front installation space 111 .

[0055] Since the drive board 30 needs to be electrically connected to the inverter unit 11, and the controller 20 needs to be electrically connected to external equipment, by fixing the drive board 30 on the front installation space 111 of the inverter unit 11, the communication cable between the drive board 30 and the inverter unit 11 can be shortened and simplified; and the controller 20 is fixedly installed on the front panel 12 of the installation plate 12, so that the communication cable between the controller 20 and the external equipment can be shortened and simplified, which greatly reduces the problems of low reliability such as interference of the communication cable by strong electricity, magnetic field signals generated by EMC (electromagnetic compatibility), and easy failure.

[0056] Optionally, see Figures 4 to 6 In one embodiment of the fixing device 10 of the utility model, the fixing device 10 also includes a support member 14, which is movably disposed in the front mounting space 111 and has a first state and a second state; when the mounting plate 12 is in the first position, the support member 14 is in the first state, used to avoid the mounting plate 12; when the mounting plate 12 is in the second position, the support member 14 is in the second state, used to support the mounting plate 12.

[0057] With such arrangement, when the mounting plate 12 needs to move to the first position, the support member 14 can be moved to the first state to avoid the mounting plate 12 so that the mounting plate 12 can move smoothly to the first position; when the mounting plate 12 moves to the second position, the support member 14 can be moved to the second state to support the mounting plate 12 so that the mounting plate 12 is stabilized in the second position, thereby preventing the mounting plate 12 from returning to its original position and affecting the user's operation when the user operates the controller 20 or the drive board 30 in the installation space 111 on the front side of the inverter unit 11.

[0058] In actual application, the support member 14 can be moved relative to the front installation space 111 of the inverter unit 11 by sliding, rotating, withdrawing, etc., so as to switch between the first state and the second state.

[0059] In actual application, the support member 14 can be a support structure member in the shape of a rod, a plate, a strip, a block, etc., which is not specifically limited here.

[0060] Optionally, see Figures 4 to 6 In one embodiment of the fixing device 10 of the present invention, the support member 14 is rotatably or detachably disposed in the front installation space 111 to switch between the first state and the second state.

[0061] In one embodiment, when the support member 14 is rotatably disposed in the front mounting space 111 of the inverter, the user can pry the support member 14 to switch the support member 14 between the first state and the second state. At the same time, the movement of the support member 14 will not be restricted by the internal space of the inverter box, thereby ensuring that the support member 14 has a sufficient range of motion and can smoothly switch between the first state and the second state.

[0062] In another embodiment, when the support member 14 is detachably provided in the front mounting space 111 of the inverter, the user can directly remove the support member 14 from the front mounting space 111 of the inverter to move the mounting plate 12 to the first position, and can directly place the support member 14 in the front mounting space 111 of the inverter to support the mounting plate 12 in the second position; during the production process, there is no need to equip each fixing device 10 with a support member 14, and one or several support members 14 can be provided for use by multiple fixing devices 10, which can reduce the preparation cost.

[0063] Optionally, see Figure 4 In one embodiment of the fixing device 10 of the present invention, the mounting plate 12 is provided with a limiting hole 122 , and when the support member 14 is in the second state, one end of the support member 14 away from the front mounting space 111 is limitedly matched with the limiting hole 122 .

[0064] With such arrangement, the support member 14 can more stably support the mounting plate 12 through cooperation between the end portion and the limiting hole 122 .

[0065] In some embodiments, the support member 14 may include a first support rod and a second support rod set at an angle. When the support member 14 is in the second state, the end of the first support rod away from the second support rod can be inserted into the installation groove of the front installation space 111, and the end of the second support rod away from the first support rod can be inserted into the limiting hole 122. In this way, the support reliability of the support member 14 on the mounting plate 12 can be improved.

[0066] Optionally, a limiting protrusion can be provided at the end of the second support rod away from the first support rod, so that the limiting protrusion can be inserted into the limiting hole 122 of the mounting plate 12, and the end of the second support rod away from the first support rod can abut against the side of the mounting plate 12 facing away from the front plate surface 12. In this way, the supporting reliability of the support member 14 on the mounting plate 12 can be further improved.

[0067] Combined with reference Figures 1 to 6 The utility model further proposes an inverter unit 100, which includes a controller 20, a drive board 30 and the fixing device 10 as described above. The specific structure of the fixing device 10 refers to the above embodiment. Since the inverter unit 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0068] Optionally, in an embodiment of the inverter unit 100 of the present invention, the controller 20 is connected to an external device via a wire harness, and the wire harness is bound by a binding belt, and the binding belt can be movably bound to the wire harness.

[0069] With such arrangement, by making the strapping belt movably tied to the wiring harness, the mounting plate 12 can move the strapping belt or directly remove the strapping belt during its movement, thereby ensuring that the mounting plate 12 is not affected by the strapping belt during its movement, thereby reducing the risk of the wiring harness being bent, worn or even broken.

[0070] The utility model also provides a converter, which includes a converter housing and the inverter unit 100 as described above. The specific structure of the inverter unit 100 refers to the above embodiment. Since the converter adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
