It will be described as constituting a preferred form.

(Embodiment 1)
FIG. 1 is a perspective view illustrating a power feeding system including a power feeding device and a power supplied device.

  As illustrated in FIG. 1, the power supply system 100 includes a power supply apparatus 101 that supplies power to a power supplied apparatus 102 having a power receiving coil 121. The power supply apparatus 101 includes a base body 112, a suspension part 113, a restriction part 114, a contact surface part 115, and a power supply coil 111. In the case of the present embodiment, the power supply apparatus 101 further includes a bottom receiving portion 116, a passage portion 117, and an anti-sway portion 118.

  The base body 112 is a member having a back surface portion 119 disposed along a vertical plane (a plane along the XZ plane in the drawing) in a state of being attached to the mounted member 200. In the case of the present embodiment, the base body 112 is a case for housing a power feeding circuit and the power feeding coil 111, and includes an upper cover 112a and a lower cover 112b formed of resin. The base 112 is attached to the member to be attached 200 with screws or the like.

  Here, the attached member 200 is not particularly limited, but is a member including, for example, a wall, a pillar, a machine tool, or the like, and having a vertical surface or a surface inclined close thereto.

  The suspending portion 113 is provided on the upper portion of the base body 112 so as to hang forward from the base body 112 opposite to the attached member 200 (the positive side in the Y-axis direction in the drawing). It is a member. In the case of the present embodiment, the suspending portion 113 is formed by integral molding of the resin together with the upper cover 112a of the base body 112, thereby improving the mechanical strength. The hanging portion 113 is provided at the center portion in the width direction (X-axis direction in the drawing) of the base body 112 and has a width that is about one third of the width of the base body 112. This facilitates maintaining the balance in the width direction when the power-supplied device 102 is suspended, and improves the mechanical strength of the suspended portion 113.

  The restricting unit 114 is a part that is provided in the hanging part 113 and restricts the upper part of the suspended power-supplied device 102 from moving beyond a predetermined distance with respect to the base body 112. In the case of the present embodiment, the restricting portion 114 is provided integrally with the hanging portion 113 so as to protrude obliquely upward from the tip of the hanging portion 113. In addition, a rounded portion is provided at the tip of the restricting portion 114 to reduce resistance when the ring portion 123 of the power supplied device 102 is inserted and removed.

  FIG. 2 is a side view schematically showing a cross section of the power feeding device and the power-supplied device in a state suspended from the power feeding device.

  As shown in these drawings, the contact surface portion 115 is provided at the lower portion of the base body 112, and in a state where the power-supplied device 102 is suspended by the suspension portion 113, a suspended portion (for example, the vicinity of the regulating portion 114) is provided. It is a part that contacts and pushes the lower part of the power-supplied device 102 so that the center of gravity G of the power-supplied device 102 is located on the front side (the Y-axis direction positive side in the figure) with respect to the passing vertical line V. In the case of the present embodiment, the contact surface portion 115 is provided obliquely along the back surface of the power-supplied device 102 that is suspended obliquely. The contact surface portion 115 is formed by integral molding of resin together with the upper cover 112a of the base 112.

  Note that the base body 112, the contact surface portion 115, and the like are cavities in which the electric wire 103 is wired and a circuit board or the like is disposed, and a large number of ribs are provided for ensuring strength.

  In addition, the inclination with which the power-supplied device 102 is inclined by the restriction portion 114 and the contact surface portion 115 of the hanging portion 113 is preferably about 3 degrees or more and 10 degrees or less.

  The power feeding coil 111 is a coil that is disposed inside the contact surface portion 115 and feeds power to the power receiving coil 121 in a non-contact manner by electromagnetic induction. The power supply coil 111 is disposed at a position facing the power reception coil 121 in a state where the power supplied apparatus 102 is suspended.

  The bottom receiving portion 116 is a portion that is disposed below the power-supplied device 102 in a state where the power-supplied device 102 is attached, and is provided so as to protrude forward from the base body 112 (contact surface portion 115). In the case of the present embodiment, the bottom receiving portion 116 is a wall-like member, and is formed by integral molding of resin together with the upper cover 112a of the base 112. In general, in a state where the power supplied device 102 is suspended from the hanging portion 113, the power supplied device 102 and the bottom receiving portion 116 are not in contact with each other. For example, the bottom receiving unit 116 prevents the power-supplied device 102 from dropping from the power supply device 101 when the suspension unit 113 in a state where the power-supplied device 102 is suspended is damaged. Further, even in a situation where the suspending portion 113 is damaged, by placing the power supplied device 102 on the bottom receiving portion 116, the power feeding coil 111 and the power receiving coil 121 can be opposed to each other. It becomes possible to supply power to In particular, in the case of the present embodiment, the bottom receiving portion 116 is inclined such that the upper surface portion of the bottom receiving portion 116 is lowered from the front tip portion toward the base 112 in a state where the base 112 is attached to the attached member 200. doing. Furthermore, in a state where the power supplied device 102 is also attached to the power supplying device 101, the lower surface portion of the power supplied device 102 is similarly inclined so as to descend from the front tip portion toward the base body 112. As a result, a force is generated in a direction in which the power supply apparatus 101 and the power supplied apparatus 102 are brought into close contact with each other by gravity in a state where the power supplied apparatus 102 is placed on the bottom receiving portion 116. Therefore, efficient power feeding can be performed. On the other hand, the center of the power feeding coil 111 and the center of the power receiving coil 121 are left and right even when vibration in the left and right direction (X direction) is applied to the power supplied device 102 by the left and right anti-sway portion 116a formed in the bottom receiving portion 116. It is configured not to deviate.

  The passage part 117 is a space provided in the bottom receiving part 116, and is a hole or notch penetrating in the vertical direction. In the case of the present embodiment, the passage portion 117 is a portion in which the central portion of the bottom receiving portion 116 is cut from the tip of the bottom receiving portion 116 to the base body 112 (contact surface portion 115). In the state where the power feeding device 101 is attached to the member to be attached 200, the passage portion 117 can be dropped downward from the power feeding device 101 even when a cutting piece, dust or the like tries to get on the bottom receiving portion 116. Become.

  The anti-sway portion 118 is a plate-like portion provided to protrude upward at the tip of the bottom receiving portion 116. The anti-sway unit 118 shakes with the front surface of the lower end of the power-supplied device 102 when the power-supply device 101 vibrates and swings around the regulating unit 114 while the power-supplied device 102 is suspended by the suspension unit 113. This is a part that suppresses the shake of the power supplied apparatus 102 due to interference with the upper edge of the stopper 118. The anti-sway portion 118 is set to a height that hardly interferes with the power-supplied device 102 when the power-supplied device 102 is slightly lifted in order to attach or detach the power-supplied device 102 to or from the power supply device 101.

  The power supply system 100 including the power supply apparatus 101 as described above can be operated by attaching the power supply apparatus 101 to a wall or a wall surface of a machine tool housing. Therefore, the space required for the power supply system 100 can be saved. In addition, since the power supply device 101 is arranged along the vertical plane, it is possible to avoid cutting chips and dust from getting on the front surface of the power supply device 101. Furthermore, since the power-supplied device 102 can be maintained obliquely by the regulating portion 114 and the contact surface portion 115 in a state where the power-supplied device 102 is suspended from the suspending portion 113, the contact surface portion 115 and the power-supplied power are supplied by gravity. A force is generated that comes into close contact with the lower part of the device 102. Therefore, the feeding coil 111 and the receiving coil 121 can be opposed to each other in a stable state, and a stable charging state can be ensured.
