1. Field of the Invention
The present invention relates to the modularization of a linear actuator, and in particular to a power supply module of a linear actuator and a conversion assembly thereof
2. Description of Prior Art
Traditionally, the transformer 13a in the power supply module 1a is an EI transformer which only has a voltage-converting function. Further, the EI transformer has a large weight and does not conform to the requirements for environmental protection. Thus, the EI transformer has to be replaced by a new type of transformer. The present invention aims to maintain the modular structure of the power supply module 1a and to accommodate new components therein.
In order to solve the above problems, the present Inventor proposes a novel and reasonable structure based on his expert knowledge and deliberate researches.
The present invention is to provide a power supply module of a linear actuator and a conversion assembly thereof A rectifying element, a filtering element and etc. are arranged on a circuit board to form a voltage converter having rectifying and filtering functions. By this arrangement, the conventional EL transformer having a large weight and size can be replaced. Alternatively, a rectifying element and a filtering element are mounted in an internal space of the power supply module to achieve the rectifying and filtering functions.
The present invention provides a power supply module of a linear actuator, including a casing, a circuit control unit, and a conversion assembly. The casing is provided with a dividing plate for dividing the interior of the casing into a first space and a second space. The circuit control unit is disposed in the first space, and the conversion assembly is disposed in the second space. The conversion assembly further comprises a circuit board set and a frame. The circuit board set is electrically connected with an inductive element, a rectifying element and a filtering element. The circuit board set is mounted onto the frame to form a modular structure.

The casing 10 is configured to integrate the circuit control unit 11 and the conversion assembly 2. The casing 10 is constituted of a base 100 and an upper cover 101. The base 100 is provided with a dividing plate 102 for dividing the interior of the casing 10 into a first space 103 and a second space 104. The power control unit 11 is disposed in the first space 103. The conversion assembly 2 is disposed in the second space 104. By this arrangement, the casing 10 can integrate the respective components of the power supply module 1 into a modular structure.

The frame 21 comprises a frame base 210 and a frame cover 211. The circuit board set 20 is sandwiched between the frame base 210 and the frame cover 211. The frame base 210 has a first side plate 212. One end of the first side plate 212 is provided with a first base plate 213. The first side plate 212 is provided with a second base plate 214 separated from the first base plate 213 by an interval. The first circuit board 200 of the circuit board set 10 is accommodated between the first base plate 213 and the second base plate 214. The frame cover 211 has a second side plate 215. One end of the second side plate 213 is provided with a cover plate 216. The cover plate 216 is separated from the second base plate 214 of the frame base 210 by an interval, so that the second circuit board 201 of the circuit board set 20 is accommodated between the second base plate 214 and the cover plate 216. The distal edge of the first base plate 213 is provided with a first buckling portion 217. The first buckling portion 217 outwardly buckles the inner edge of the other end of the second side plate 215. The other end of the first side plate 213 of the frame base 210 is assembled with the distal edge of the cover plate 216 of the frame cover 211. The distal edge of the cover plate 216 is provided with a second buckling portion 218. The second buckling portion 218 inwardly buckles the outer edge of the other end of the first side plate 213. In this way, the frame 21 can be obtained, in which the circuit board set 20 is mounted.
It should be noted that the first side plate 212, the second side plate 215, and the cover plate 216 of the frame 21 may be hollowed to facilitate the heat dissipation of the conversion assembly 2 or the electrical connection with other external components.
With the above structure, the power supply module of a linear actuator and the conversion assembly thereof can be obtained.
