Description

Technical Field

[0001] This invention relates to the field of drive technology, and in particular to an electric hoist drive that is adaptable to various front mounting orientations. Background Technology

[0002] Currently, the drivers used in electric hoists typically employ either general-purpose frequency converters or hoist-specific frequency converters. The operating interface direction and wiring positions are fixed for each manufacturer. When such a driver is installed inside the electric hoist cavity, the orientation of the operating interface, especially the parameter display direction and wiring position, is fixed in one direction when viewed from the front. This approach has the following drawbacks: Each hoist manufacturer produces electric hoists with diverse lifting and cable exit directions, which are completely different. The driver's wiring direction must match the hoist's cable exit direction. When the driver is installed inside the hoist cavity, the operating interface display direction may be upward, downward, left, or right, making it very inconvenient to observe and adjust parameters using buttons. If it is necessary to ensure that the driver's operating interface matches the hoist's lifting interface (which is always upward), the driver's wiring position will likely be inconsistent with the hoist's cable exit position, resulting in a very convoluted cable route or insufficient bending space. The cable cannot be routed from the driver's wiring position to the hoist's cable exit position, making assembly impossible.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electric hoist driver that is adaptable to various front-mounting orientations.

[0005] The technical solution of the present invention is as follows: The present invention provides an electric hoist driver adaptable to multiple front mounting directions, including: a flip cover, a bottom power component, a membrane button, and four of the following: a first direction conversion component, a second direction conversion component, a third direction conversion component, and a fourth direction conversion component, one of which is assembled with the bottom power component and the membrane button. Each of the first direction conversion component, the second direction conversion component, the third direction conversion component, and the fourth direction conversion component includes a control board and a faceplate. The faceplate is sleeved on the bottom power component. The control board is disposed within the accommodating space formed by the faceplate. The flip cover is rotatably connected to the faceplate and is positioned at the wiring terminal position of the electric hoist driver. A button mounting area is formed on the faceplate. The membrane button is mounted on the button mounting area and electrically connected to the control board. The button portion of the membrane button is square.

[0006] When the first direction conversion component is selected, the wiring terminals of the electric hoist driver are located below the membrane key.

[0007] When the second direction conversion component is selected, the wiring terminals of the electric hoist driver are located to the right of the membrane key.

[0008] When a third-party direction conversion component is selected, the wiring terminals of the electric hoist driver are located to the left of the membrane key.

[0009] When the fourth direction conversion component is selected, the wiring terminals of the electric hoist driver are located above the membrane key.

[0010] Furthermore, the solution includes at least three of the following: a first direction conversion component, a second direction conversion component, a third direction conversion component, and a fourth direction conversion component, and one of them is assembled with the underlying power component and the membrane key.

[0011] Furthermore, the solution includes four of the following components: a first direction conversion component, a second direction conversion component, a third direction conversion component, and a fourth direction conversion component, and one of them is selected for assembly with the underlying power component and the membrane key.

[0012] Furthermore, the button mounting area of ​​the faceplate has a ribbon cable through hole and a display window through hole, the button part of the membrane button is mounted on the button mounting area, the ribbon cable of the membrane button passes through the ribbon cable through hole, and the ribbon cable interface of the membrane button is mounted on the terminal block of the control board.

[0013] Furthermore, the control board is provided with a display unit, which is correspondingly disposed at the display window through hole of the faceplate.

[0014] Furthermore, the faceplate is produced by injection molding, the injection molding including a movable insert for forming the button mounting area, and by setting different setting angles of the movable insert, faceplates for the first direction conversion component, the second direction conversion component, the third direction conversion component, and the fourth direction conversion component are respectively formed in the injection molding.

[0015] The beneficial effects of the present invention by adopting the above solution are as follows: by selecting direction conversion components of different directions, it can adapt to electric hoists with different hoisting and cable output directions. Using the same driver, under the premise of ensuring that the wiring direction is adapted to the cable output direction of the hoist, the operation display interface of the driver is always consistent with the hoisting direction of the hoist (upward). Furthermore, it achieves low cost and good universality and interchangeability of accessories such as the underlying power components, membrane keyboard and flip cover, which helps to reduce production and configuration costs.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to the following: Figures 1 to 6 In this embodiment, the present invention provides an electric hoist driver adaptable to multiple front mounting orientations, comprising: a flip cover 2, a bottom power component 3, a membrane keypad 4, and four of the following: a first direction conversion component 51, a second direction conversion component 52, a third direction conversion component 53, and a fourth direction conversion component 53. One of these components is selectively assembled with the flip cover 2, the bottom power component 3, and the membrane keypad 4. Each of the first, second, third, and fourth direction conversion components 51, 52, 53, and 53 includes a control board 7 and a faceplate 6, thus providing four mounting orientations. The bottom power component 3 includes a power board, a heat sink, a bracket, and other components. The faceplate 6 is fitted onto the bottom power component 3. The control board 7 is disposed within the accommodating space formed by the faceplate 6. The flip cover 2 is rotatably connected to the faceplate 6 and is positioned at the wiring terminal location of the electric hoist driver. The wiring terminals of the electric hoist driver include the control terminal 73 of the control board 7 and the power terminal of the bottom power component 3. A button mounting area 62 is formed on the faceplate 6. The membrane button 4 is mounted on the button mounting area 62 and electrically connected to the control board 7. The button part 41 of the membrane button 4 is square. This structure can ensure that the membrane button 4 can be adapted to use the corresponding faceplate 6 when different direction conversion components are selected.

[0024] In this design, the button mounting area 62 of the faceplate 6 has a ribbon cable through hole 63 and a display window through hole 61. The button portion 41 of the membrane key 4 is mounted on the button mounting area 62, the ribbon cable 43 of the membrane key 4 passes through the ribbon cable through hole 63, and the ribbon cable interface 42 of the membrane key 4 is mounted on the wiring port 72 of the control board 7. The control board 7 is provided with a display unit 71, which is correspondingly located at the display window through hole 61 of the faceplate 6, and the membrane key 4 has a display area corresponding to the display unit.

[0025] In this solution, the faceplate 6 is produced by injection molding. The faceplates 6 of the first direction conversion component 51, the second direction conversion component 52, the third direction conversion component 53, and the fourth direction conversion component 53 have the same appearance and internal cavity features, and their only difference is the button mounting area 62 used to install the membrane button 4. Therefore, in the injection mold for producing the faceplate 6, the injection mold includes a movable insert for forming the button mounting area 62. By setting different setting angles (0 degrees, 90 degrees, 180 degrees, and 270 degrees) of the movable insert, the installation position of the button mounting area 62 in the faceplate 6 is different during injection molding. This allows the faceplates 6 of the first direction conversion component 51, the second direction conversion component 52, the third direction conversion component 53, and the fourth direction conversion component 53 to be formed respectively. This means that only the angle of the insert needs to be set during production, without the need to re-mold, which can reduce production costs and improve production efficiency.

[0026] Please refer to the following: Figures 1 to 3 When the first direction conversion component 51 is selected, the wiring terminals of the electric hoist driver are located below the membrane key 4.

[0027] Please refer to the following: Figure 4 When the second direction conversion component 52 is selected, the wiring terminal of the electric hoist driver is located to the right of the membrane key 4.

[0028] Please refer to the following: Figure 5 When the third-party direction conversion component 53 is selected, the wiring terminal of the electric hoist driver is located to the left of the membrane key 4.

[0029] Please refer to the following: Figure 6 When the fourth direction conversion component 53 is selected, the wiring terminals of the electric hoist driver are located above the membrane key 4.

[0030] Please continue to refer to the following: Figures 1 to 6In this solution, when selecting four different orientation conversion components, the flip cover 2, the bottom power component 3, and the membrane keyboard are all the same. This allows for low-cost adaptation to different orientation installation requirements. Furthermore, when the orientation of the driver on the operating interface is always consistent with the hoisting direction of the electric hoist and always facing upwards, its wiring position can face any of the four directions, adapting to the outgoing wire opening direction of any manufacturer's electric hoist.

[0031] In summary, by selecting direction conversion components with different orientations, electric hoists with various lifting and cable output directions can be adapted. Using the same driver, while ensuring that the wiring direction adapts to the hoist's cable output direction, the driver's operation display interface orientation is always consistent with the hoist's lifting direction (upward). Furthermore, this approach achieves low cost and good universality and interchangeability of accessories such as the underlying power components, membrane keyboard, and flip cover, which helps reduce production and configuration costs.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
