Definitions

  • the invention relates to the technical field of shelf power supplies, in particular to a power supply device and a power supply shelf, in particular a shelf system comprising at least one such power supply device.
  • LED lamps are more and more used in the fields of home and commercial lighting because of their high light emission efficiency and good light-gathering performance.
  • shelf lighting is a kind of commercial lighting.
  • power supply rails tracks
  • the power supply rails are usually all exposed, so that they can easily corrode and be damaged.
  • the power supply rails are not waterproof, so it is difficult to apply such shelves or shelf systems in areas under high moisture conditions and humidity, where watertightness is needed.
  • the present invention is to provide a power supply device for shelves and a power supply shelf to solve the above technical problems.
  • a power supply device for shelves and a power supply shelf configured to reliably provide electric power to at least one shelf of a shelf system with a low-cost set-up that can be assembled, disassembled and modified in a versatile manner.

  • the flexible conductive strip may be provided with a magnetic element.
  • the first fixing member may be a T-shaped bump or protrusion provided on one side of the fixed power supply unit, configured to be inserted into a corresponding mounting hole of a back board. More specifically, by first tilting the fixed power supply unit relative to the plane of the back board, then inserting one of the two arms of the T-shaped bump or protrusion, then the protrusion itself and then the second of the two arms of the T-shaped bump or protrusion and then tilting backward the fixed power supply unit so as to be disposed in parallel with the plane of the back board, the T-shaped bump or protrusion may be fixed in a positive-fit manner in the mounting hole of the back board, so as to be disposed fixed at the location of the mounting hole on the back board.
  • the two arms of the T-shaped bump or protrusion may be resiliently biased against a shaft of the T-shaped bump or protrusion, and may be pushed inward towards the shaft so that the shaft may be inserted into a mounting hole of the back board, and after releasing the two arms again, they may return back to their biased home position, to thereby fix the fixed power supply unit in a positive-fit manner in the mounting hole of the back board.
  • the fixed power supply unit may be provided with a second socket, which may be disposed in particular on a side opposite to that side of the fixed power supply unit where the first socket is provided.
  • power may also be supplied at the rear side of e.g. a back board of the shelf system.

  • the total number of such power supply modules 1000 may be set e.g. according to the total number of layers (shelves) of the shelf system.
  • one power supply module 1000 may be provided for each layer of the shelf system.
  • multiple layers or power supply modules 1000 may also be set for a single layer.
  • Each power supply module 1000 includes: a fixed power supply unit 100 intended to be fixedly positioned, stationary, at a predetermined location of a back board as outlined hereinafter, a sliding power supply unit 200 that can be moved on a back board by sliding to a desired position, if required, and a flexible conductive strip 300, which electrically connects the fixed power supply unit 100 and the associated sliding power supply unit 200.
  • the fixed power supply unit 100 comprises a first fixing member 101 and is connected to a power supply (not shown in the drawings).
  • the sliding power supply unit 200 comprises a first socket or plug-in interface 201 (see Fig. 5 ), and the two ends of the flexible conductive strip 300 are electrically connected to the fixed power supply unit 100 and the sliding power supply unit 200, respectively.
  • the fixed power supply unit 100 is connected to an external power supply for power supply, whereas the sliding power supply unit 200 can be moved relative to the fixed power supply unit 100 by sliding, e.g. along grooves or slots provided in the back board, so as to provide a power supply function at a specific position as actually required by the geometry of the shelf system to be supplied with electric power, while the flexible conductive strip 300 is bent accordingly by bending to supply electric power to the sliding power supply unit 200.
  • the length of the flexible conductive strip 300 may basically correspond to the length of a longitudinal guiding slot 3002, 2002 provided in the back board 2000 plus the distance between the mounting position of the fixed power supply unit 100 at the back board to the associated guiding slot 3002, 2002, as shown in Fig. 3 .
  • each power supply module 1000 The fixed power supply units 100 of each power supply module 1000 are electrically connected sequentially, and in this embodiment, the power supply modules 1000 are electrically connected through the flexible conductive strip 300, which is convenient for folding and transportation.
  • a flexible waterproof layer may be wrapped on the outside of all the components of a power supply module 1000.
  • the flexible conductive strip 300 is a wire with an insulating layer applied directly upon it, and the waterproof effect can be realized as long as the insulating layer is waterproof.
  • Other parts or components of the power supply module 1000 are generally waterproofed by encapsulation.
  • the flexible conductive strip 300 may be provided with at least one magnetic element 400.
  • the magnetic element 400 can be attracted by a back board of a shelf system including e.g. a ferro-magnetic layer, so that the flexible conductive strip 300 can always maintain a general shape and does not project too far from the rear surface of the associated back board 2000, and is not easily entangled.
  • the first fixing member 101 should be easy to assemble and disassemble.
  • the first fixing member 101 is embodied as a T-shaped bump arranged on one side of the fixed power supply unit 100.
  • the T-shaped bump may be fixedly mounted into a mounting hole of the back board, as outlined above.
  • the sliding power supply unit 200 includes at least the following: a first base 202 provided with the first socket 201 on one side; a first top cover 203 connected to the first base 202 with a gap for accommodating a back board 2000 or similar holding plate, having a first insertion hole 2031 aligned with the first socket 201.
  • first base 202 and the first top cover 203 are connected through first connecting pieces 204 arranged on both sides of the first socket 201.
  • a damping unit is provided between the first base 202 and the first top cover 203 so as to maintain a positional relationship and gap between the first base 202 and the first top cover 203, e.g. including resilient members such as springs to resiliently bias the first base 202 and the first top cover 203 against each other.
  • the damping unit may be also embodied as a plurality of protrusions, in particular elastic or resilient protrusions, but it may also be realized in a tight fit manner, and there are many ways, so that it is not necessary to go into the details.
