Hereinafter, the above description will be described in detail by way of implementation, and a further explanation will be provided for the technical solution of the present invention.

In order to make the description of the present invention more detailed and complete, please refer to the attached drawings and various embodiments described below. The same numbers in the drawings represent the same or similar elements. On the other hand, well-known elements and steps are not described in the embodiments to avoid unnecessary limitations on the present invention.

Please refer to FIG. 1, which shows a power module fixed on a supporting rail according to an embodiment of the present invention. The power module 100 includes a housing 102, a bracket 104, a sliding member 106, and an elastic recovery member 108. The housing 102 has a first surface 102a, a second surface 102b, and a third surface 102c. The second surface 102b and the third surface 102c are respectively perpendicularly connected to two opposite sides of the first surface 102a. The bracket 104 is fixed on the first surface 102a. In this embodiment, the bracket 104 has a pair of hooks 104a for buckling a first side 202 of a support rail 200 (in other embodiments, the bracket 104 may There is only one hook, no need for a pair of hooks), it also has a pair of support members 104b abutting on the second side 204 of the support rail 200, the second side 204 and the first side 202 are respectively located on the two sides of the support rail 200 Opposite side. The sliding element 106 is slidably connected to the bracket 104, and the sliding element 106 has a fastener 106 a for engaging the second side 204 of the supporting rail 200. One end of the elastic recovery member 108 is fixed to the bracket 104 and the other end is connected to the sliding member 106. The elastic return member 108 is used to apply force to the sliding member 106 so that the pair of hooks 104 a and the fastener 106 a clamp the support rail 200 so that the power module 100 can be fixed on the support rail 200. The supporting rail 200 also has a plurality of lock holes, which can be locked on a wall or other surface of the body. The sliding member 106 has a first unlocking end 106b' for applying a force to oppose the elastic return member 108, wherein the first unlocking end 106b' protrudes beyond the second surface 102b.

Please refer to FIG. 2, which shows an enlarged view of the sliding member 106 of the power module of FIG. 1. One end of the elastic return member 108 is fixed to the positioning member 104e of the bracket 104, and the other end is connected to the positioning member 106d of the sliding member 106. In this embodiment, the elastic return member 108 is a compression spring, but it is not limited to this. The first unlocking end 106b' has a force through hole 106b for inserting a jig to apply force against the elastic return member 108, so that the fastener 106a is separated from the supporting rail 200, thereby unlocking the power module. The positioning member 104c of the bracket 104 is used to position the sliding member 106 to slide on a predetermined path.

Please refer to FIG. 3, which is an enlarged view of the bracket 104 of the power module of FIG. 1 (the sliding member 106 has been removed). An end 104d of the bracket 104 close to the second surface 102b extends and protrudes from the second surface 102b to form a protrusion.

Please refer to FIG. 4, which is an enlarged view of the bracket 104 of a power module according to another embodiment of the present invention. In this example, the bracket 104 does not have an end 104d protruding from the second surface 102b (refer to FIG. 3), and the protrusion 102b' is formed by bending the portion of the housing 102 on the second surface 102b .

Please refer to FIG. 5, which is a schematic diagram of unlocking the power module using a jig 150 according to another embodiment of the present invention. The aforementioned protrusion 102b' protruding from the second surface 102b is used as a fulcrum for the jig 150 to apply force. When one end of the jig 150 is inserted into the force through hole 106b of the first unlocking end and the protruding member 102b' is used as a fulcrum to apply force against the elastic restoring member 108, the required force is less than when the jig 150 is used for unlocking without the protruding member 102b'. The force required is much reduced.

Please refer to FIG. 6, which shows an enlarged view of the sliding member 106 of a power module according to another embodiment of the present invention. In this example, the first unlocking end of the sliding member 106 is designed as a force application plate 106c instead of the aforementioned force application through hole. The aforementioned jig 150 can also be used to drive the force application plate 106c against the elastic return member 108. In this example, the force application plate 106c is substantially parallel to the second surface 102b, but not limited to this.

Please refer to FIG. 7, which shows an enlarged view of a lever structure of a power module according to still another embodiment of the present invention. In addition to using the aforementioned jig, a lever structure 160 can also be provided on the second surface 102b to apply force to the unlocking end. The lever structure 160 has a force application rod 162, the middle section 162b of which is pivotally connected to the fulcrum 102b" protruding from the second surface 102b. One end portion 162c of the force application rod 162 is used to insert the force application through hole 106b of the first unlocking end. When the other end 162a of the force rod 162 is driven, the sliding member 106 can be driven against the elastic return member 108, thereby unlocking the power module from the support rail 200. When the position of the supporting point 102b" is set closer to the end 162c (relatively Compared with the distance from the other end 162a), the unlocking of the power module will be less effort (that is, the less the unlocking force required to be applied to the end 162a).

Please refer to FIG. 8, which is a perspective view of a power module of a power module according to another embodiment of the present invention. Different from the foregoing embodiment, in addition to the first unlocking end, the sliding member 106' also has a second unlocking end protruding beyond the third surface 102c. In this embodiment, the second unlocking end has a force application plate 106f, which is substantially parallel to the third surface 102c, but not limited to this. Both the first unlocking end and the second unlocking end of the sliding member 106' can be used to apply force against the elastic restoring member 108, so that the fastener 106a' is separated from the supporting rail 200.

To sum up, the power supply module of the present invention has a fixing mechanism, which is clamped on the supporting rail to facilitate the fixing of a plurality of power supply modules in a row. The locking part of the fixing mechanism (such as the sliding part) has an unlocking end that is easy to manually apply force, which is convenient for users to disassemble and install the power module to facilitate the arrangement of the connected lines. The power modules fixed in a row can also obtain proper heat dissipation.
