[0011] 1. One embodiment (Overall structure of electric bicycle) The moving object of one embodiment shown in FIG. 1 is an electric bicycle 1. The electric bicycle 1 is an electrically assisted bicycle. The electric bicycle 1 of one embodiment includes a frame 10, two wheels 11 rotatably connected to the frame 10, a handle portion 12, a saddle portion 13, and a motor unit 15 attached to the frame 10. The two wheels 11 are a front wheel 111 and a rear wheel 112. Of these, the rear wheel 112 is rotated by the driving force output from the motor unit 15.

[0012] The up and down directions used in this document are defined based on the electric bicycle 1 being placed on a horizontal plane. The front, back, left, and right directions used in this document are defined based on the rider of the electric bicycle 1. In other words, the direction in which the rider travels while riding the electric bicycle 1 is forward, the opposite side is backward, the direction to the left from the rider's perspective is leftward, and the direction to the right from the rider's perspective is rightward.

[0013] The frame 10 has a head tube 101, a top tube 102, a down tube 103, a seat tube 104, seat stays 105, chain stays 106, and a bracket 107. The frame 10 (i.e., the above-mentioned components constituting the frame 10) is made of a metal such as aluminum or stainless steel, but may contain a non-metallic material in part. The entire frame 10 may also be made of a non-metallic material, and the material of the frame 10 is not particularly limited.

[0014] A handlebar section 12 is rotatably attached to the head tube 101. A front fork 121 extends downward from the lower end of the handlebar section 12. A front wheel 111 is rotatably attached to the front fork 121.

[0015] The front end of the top tube 102 is fixed to the head tube 101. The rear end of the top tube 102 is fixed to the seat tube 104. The saddle portion 13 is connected to the upper end of the seat tube 104. A bracket 107 is fixed to the lower end of the seat tube 104. The down tube 103 is a tube that extends diagonally upward and forward from the bracket 107, and the front end of the down tube 103 is fixed to the head tube 101. In other words, the down tube 103 is a tube that extends diagonally downward and rearward from the head tube 101 toward the bracket 107, and the rear end of the down tube 103 is fixed to the bracket 107.

[0016] A motor unit 15 is fixed to the underside of the bracket 107. The front ends of the chain stays 106 are fixed to the rear end of the bracket 107. The front ends of the seat stays 105 are fixed to the rear end of the top tube 102. The rear ends of the seat stays 105 are connected to the rear ends of the chain stays 106, and a rear wheel 112 is rotatably attached to this connected part.

[0017] A crank arm 18 is rotatably inserted through the motor unit 15. A front sprocket 191 is provided inside the motor unit 15. A rear sprocket 192 is fixed to the hub of the rear wheel 112. A chain 193 is looped between the front sprocket 191 and the rear sprocket 192.

[0018] Furthermore, the electric bicycle 1 of one embodiment is equipped with a battery 16 for supplying power to the motor unit 15. The battery 16 is removed from the electric bicycle 1 and attached to a charger for charging. Also, a connector device 2 is provided to which an electric wire for charging is connected so that the battery 16 can be charged without removing the battery 16 from the electric bicycle 1.

[0019] (frame) As shown in Figures 2 to 5, the connector device 2 is attached to a bicycle frame 10. As shown in Figure 5, the frame 10 has a through-hole 140 in a part of a side wall 14, through which the connector device 2 is attached. As shown in Figure 5, for convenience, one direction is defined as the up-down direction. Furthermore, when the connector device 2 is attached to the frame 10, the side located inside the frame 10 (mainly the side where the main body holding portion 32 is located) is defined as the inside, and the side that contacts the outer surface 141 of the side wall 14 and faces the outside of the frame 10 (mainly the side where the attachment portion 31 is located) is defined as the outside. Furthermore, the left and right when viewed from the outside to the inside are defined as the left and right, respectively.

[0020] The side wall 14 may be any part of the frame 10, but in one embodiment is a side wall that constitutes the down tube 103. The side wall 14 is a side wall that is part of the circumferential direction of the tubular portion that constitutes the down tube 103. The shape of the through hole 140 is not particularly limited, but in one embodiment it is rectangular in front view.

[0021] The frame 10 has a sidewall mounting portion 142 in a portion of the sidewall 14 separate from the through-hole 140. The sidewall mounting portion 142 has an internal thread 143, and in one embodiment, is a through-hole that penetrates the sidewall 14, and the internal thread 143 is provided in part or all of the through-hole. Specifically, the internal thread 143 is configured by attaching the nut to the inner surface of the sidewall 14 (the surface opposite the outer surface 141) so that the internal hole of the nut communicates with the through-hole formed in the sidewall 14. The sidewall mounting portions 142 are formed in two locations, one above and one below the through-hole 140.

[0022] The connector device 2 is attached by contacting an attachment portion 31 (described later) with an outer surface 141 of the side wall 14 around the through hole 140. In one embodiment, the side wall 14 has a recess 145 in a portion of the outer surface 141 that is recessed more than the remaining portion of the outer surface 141. The attachment portion 31 is housed in the recess 145. Note that the inner surface (inner side surface and inner bottom surface) of the recess 145 also constitutes the outer surface 141.

[0023] (connector device) 2 to 5, the connector device 2 includes a holder 3, a connector body 4, and a mounting bracket 5. In one embodiment, the connector device 2 further includes a cap member 6.

[0024] (holder) 6 to 8, the holder 3 has an attachment portion 31 and a main body holding portion 32. The attachment portion 31 has an opening 310 therein that corresponds to the through hole 140 of the side wall 14. The opening 310 has a rectangular shape in a front view similar to the through hole 140, but is slightly smaller than the through hole 140.

[0025] The mounting portion 31 contacts the outer surface 141 of the side wall 14 around the through-hole 140 (see FIG. 5). As shown in FIG. 6, the mounting portion 31 is formed in an annular shape with an opening 310 therein when viewed from the front. The mounting portion 31 has plate-shaped upper and lower portions 311 and 312, and left and right portions 313 and 314 located on the left and right sides and connecting the upper and lower portions 311 and 312. The upper portion 311 is formed in a trapezoidal shape with a narrow upper end when viewed from the front. The lower portion 312 is formed in a triangular shape with a narrow lower portion when viewed from the front.

[0026] The holder 3 has holder mounting holes 33 formed as through holes at positions corresponding to the side wall mounting parts 142 of the mounting parts 31. One holder mounting hole 33 is formed in each of the upper part 311 and the lower part 312.

[0027] 7, the main body holding portion 32 extends from the inner portion of the mounting portion 31 into the through-hole 140. In one embodiment, the main body holding portion 32 extends inward from the inner edge of the mounting portion 31 (the edge of the opening 310), but it is not necessary for the main body holding portion 32 to extend from the inner edge of the mounting portion 31. The main body holding portion 32 is formed in a ring shape that is rectangular when viewed from the inside and outside directions.

[0028] The holder 3 holds the mounting bracket 5. The holder 3 holds the mounting bracket 5 inside the main body holding portion 32. The holder 3 is connected to the mounting bracket 5 so that the held mounting bracket 5 does not fall off the holder 3. The holder 3 has a holder-metal connecting portion 34 for connecting to the mounting bracket 5. The holder-metal connecting portion 34, together with the bracket-holder connecting portion 52 described below, forms a so-called snap fit, and is composed of one of the second claws and a second fitting hole into which the second claw fits, while the bracket-holder connecting portion 52 is composed of the other of the second claws and the second fitting hole. In one embodiment, the holder-metal connecting portion 34 is composed of the second claw and the bracket-holder connecting portion 52 is composed of the second fitting hole, but the holder-metal connecting portion 34 may also be composed of the second fitting hole and the bracket-holder connecting portion 52 may also be composed of the second claw. As shown in Figure 6, two holder metal fittings connecting portions 34 are formed, one at the top and one at the bottom of the left side wall of the main body holding portion 32, and one at the center in the vertical direction of the right side wall of the main body holding portion 32, for a total of three holder metal fitting connecting portions 34 formed throughout the holder 3.

[0029] Further, the holder 3 is formed with a recess 35 so that when it is connected to the connector main body 4, it can be attached in a predetermined direction and not attached in the reverse direction (see FIG. 18).

[0030] (connector body) 5 and 9, the connector body 4 has terminals 41. As shown in FIGS. 9 to 11, the connector body 4 has an outer housing 43 and an inner housing 44. The housing 43 is formed with a plug insertion hole 431 into which a plug of an electric wire for supplying power to the battery 16 is inserted, and the plug inserted from the plug insertion hole 431 comes into contact with the terminals 41.

[0031] The connector body 4 is held by the mounting bracket 5. The connector body 4 is held inside the mounting bracket 5. The connector body 4 is connected to the mounting bracket 5 so as not to fall off. The connector body 4 has a main fitting connecting portion 42 for connecting to the mounting bracket 5. The main fitting connecting portion 42, together with a fitting main connecting portion 51 described later, forms a so-called snap fit, and is composed of a first claw and one of a first fitting hole into which the first claw fits, while the fitting main connecting portion 51 is composed of the other of the first claw and the first fitting hole. In one embodiment, the main fitting connecting portion 42 is composed of the first claw and the fitting main connecting portion 51 is composed of the first fitting hole, but the main fitting connecting portion 42 may also be composed of the first fitting hole and the fitting main connecting portion 51 may be composed of the first claw. As shown in FIGS. 9 and 10 , one main fitting connecting portion 42 is formed on the upper side wall of the housing 44, and one is formed on the lower side wall of the housing 44.

[0032] The connector body 4 is formed with a protrusion 45 that fits into the recess 35 so that when connected to the holder 3, it is not attached in the reverse direction and is attached in a predetermined direction (see Figures 9 and 18).

[0033] (mounting bracket) The mounting bracket 5 holds the connector body 4 and is held by the holder 3. As shown in FIGS. 12 to 14, the mounting bracket 5 has an upper piece 53, a lower piece 54, a left piece 55, a right piece 56, and a back piece 57. The connector body 4 is positioned and held in the space surrounded by the upper piece 53, the lower piece 54, the left piece 55, the right piece 56, and the back piece 57. As shown in FIG. 12, the mounting bracket 5 is formed in a C-shape that is rectangular when viewed from the inside and outside. In other words, the mounting bracket 5 is not annular when viewed from the inside and outside. The left piece 55 is separated into an upper-left piece 551 and a lower-left piece 552, and a gap 553 is formed between the upper-left piece 551 and the lower-left piece 552, through which an electric wire can be inserted. In conventional connector devices, when attaching the connector body to a holder, the claws of the resin connector body (or holder) are hooked into holes in the resin holder (or connector body), and the connector body is fitted into the ring-shaped holder. Therefore, if it becomes necessary to remove the connector body from the holder for maintenance or the like, the claws do not easily come out of the holes and must be forcibly deformed, which can cause damage to the claws.

[0034] In contrast, the mounting bracket 5 of one embodiment is made of metal and further has a gap 553, which provides high strength and flexibility. Therefore, when removing the connector body 4 from the holder 3 for maintenance or the like, the holder-metal connecting portion 34 can be easily detached from the metal-holder connecting portion 52, preventing damage to the tabs as in conventional connector devices and allowing for repeated use. As shown in FIG. 14 , the mounting bracket 5 has a metal body connecting portion 51 for connecting to the connector body 4. The metal body connecting portion 51 is formed by a first fitting hole and fits with the main-metal connecting portion 42. One metal body connecting portion 51 is formed on the upper piece 53, and another is formed on the lower piece 54. The metal body connecting portion 51 is formed at a position corresponding to the main-metal connecting portion 42.

[0035] The fitting body connecting portion 51 is configured so as to be mateable with the main fitting connecting portion 42 but not mateable with the holder fitting connecting portion 34. In one embodiment, the holder 3, connector body 4, and mounting fitting 5 are made rectangular (non-square) when viewed from the inside and outside, so that the fitting body connecting portion 51 is mateable with the main fitting connecting portion 42 but not mateable with the holder fitting connecting portion 34. The vertical length of the body holding portion 32 of the holder 3 is longer than the distance between the left piece 55 and the right piece 56 of the mounting fitting 5.

[0036] As shown in Figure 13, the mounting bracket 5 has a bracket holder connecting portion 52 for connecting to the holder 3. The bracket holder connecting portion 52 is formed by a second fitting hole and fits with the holder bracket connecting portion 34. One bracket holder connecting portion 52 is formed on the right piece 56, one is formed on the upper left piece 551, and one is formed on the lower left piece 552. The bracket holder connecting portions 52 are formed in positions corresponding to the holder bracket connecting portions 34.

[0037] The fitting holder connecting portion 52 is configured to be mateable with the holder fitting connecting portion 34 but not mateable with the main fitting connecting portion 42. In one embodiment, the holder 3, connector body 4, and mounting fitting 5 are made rectangular (non-square) when viewed from the inside and outside, so that the fitting holder connecting portion 52 is mateable with the holder fitting connecting portion 34 but not mateable with the main fitting connecting portion 42. The vertical length of the housing 44 of the connector body 4 is longer than the distance between the left piece 55 and the right piece 56 of the mounting fitting 5.

[0038] (Cap member) 15 to 17, the cap member 6 closes the opening 310 of the holder 3. The cap member 6 has a cover portion 62 located at the outer end of the connector device 2, an insertion portion 63 that protrudes inward from the inner surface of the cover portion 62 and is inserted into the opening 310 of the holder 3, and an attachment portion 64 that extends from a part of the periphery of the cover portion 62.

[0039] The cap member 6 has a cap mounting hole 61 formed as a through-hole at a position corresponding to the side wall mounting portion 142. The cap mounting hole 61 is formed in the mounting portion 64 (see FIGS. 5, 18 and 19).

[0040] (Attachment of connector device to frame and attachment structure) The mounting structure and attachment of the connector device 2 to the bicycle frame 10 will now be described.

[0041] First, before assembling the connector device 2, the holder 3, the connector body 4, the mounting metal fitting 5, and the cap member 6 are separated from each other, as shown in FIG.

[0042] A connector body 4 connected to a battery 16 via an electric wire (not shown) is disposed within the frame 10. Because the electric wire is not long enough, the connector body 4 connected to the electric wire cannot be taken out from within the frame 10 through the through-hole 140 to the outside, and the connector body 4 and the mounting bracket 5 cannot be connected.

[0043] Next, mounting bracket 5 is inserted into frame 10 via through-hole 140, and mounting bracket 5 is connected to connector body 4 by fitting bracket body connecting portion 51 of mounting bracket 5 with main body bracket connecting portion 42 of connector body 4. At this time, mounting bracket 5 is not annular, and a gap 553 is formed in mounting bracket 5, so that the electric wire connected to connector body 4 can be passed through gap 553 to connect mounting bracket 5 to connector body 4.

[0044] Next, the unit of the connected connector body 4 and mounting bracket 5 is pulled out through the through hole 140 so that the connector body 4 is positioned outward.

[0045] Next, as shown in Figure 19, the metal holder connection portion 52 of the mounting bracket 5 is engaged with the holder metal connection portion 34 of the holder 3, thereby connecting the holder 3 and the mounting bracket 5, and ultimately the holder 3 and the unit of the connector body 4 and mounting bracket 5.

[0046] Next, the holder mounting hole 33 of the holder 3 is connected to the cap mounting hole 61 of the cap member 6, and as shown in Fig. 5, the cap mounting hole 61, holder mounting hole 33, and side wall mounting portion 142 are connected to each other, and a male screw 144 is inserted through the cap mounting hole 61 and screwed into the female screw 143. The mounting portion 31 and the cap member 6 are sandwiched between the head of the male screw 144 and the side wall 14, and the connector device 2 is attached to the frame 10. The male screw 144 forms an attachment means for attaching the holder mounting portion and the cap mounting portion to the side wall mounting portion 142. Note that such attachment means may be press-fitting, adhesive, or the like, and is not limited to the male screw 144.

[0047] (Action and effect) By providing a mounting bracket 5 that holds the connector body 4 and is held by the holder 3, the unit of the holder 3, connector body 4, and mounting bracket 5 can be attached to the outer surface 141 of the side wall 14 of the frame 10 from outside the frame 10 with a male screw 144. This makes it easier to attach the connector device 2 to the frame 10, as there is no need to hold both the bicycle connector located inside the frame and the engagement part located outside the frame, as is the case with the invention described in Patent Document 1.

[0048] Furthermore, the connector body 4 and the mounting bracket 5, and the holder 3 and the mounting bracket 5 can be connected by fitting the tabs into the fitting holes, improving workability.

[0049] In addition, incorrect connection between the metal fitting main body connecting portion 51 and the holder metal fitting connecting portion 34, and incorrect connection between the metal fitting holder connecting portion 52 and the main body metal fitting connecting portion 42 can be prevented.

[0050] Furthermore, the side wall 14 has a recess 145 that is recessed further than the outer surface 141 of the other portion, and the attachment portion 31 is housed in the recess 145, so that the attachment portion 31 (connector device 2) does not protrude from the outer surface 141.

[0051] (Variation) The mobile object of the present disclosure is not limited to bicycles, but may include various mobile objects such as motorcycles, tricycles, and other vehicles.

[0052] Each of the components of the electric bicycle 1 of one embodiment is merely an example, and can be modified as appropriate within the scope of achieving the same operational effects.

[0053] For example, the electric bicycle 1 in one embodiment is an electrically assisted bicycle, but it may also be an electric bicycle in which at least one of the front wheel 111 and the rear wheel 112 can be rotated by the rotational force of an electric motor alone. The electric bicycle 1 in one embodiment has two wheels 11, but the number of wheels 11 is not particularly limited, and it is also possible to have three wheels 11, for example.

[0054] The connector device 2 is for charging the battery 16 on the electric bicycle 1 without removing it, but the use of the connector device 2 is not limited thereto. The connector device 2 may also be a connector device for connecting electric wires for supplying power or performing communications on a bicycle that does not have a battery 16. In other words, the bicycle to which the connector device 2 of the present disclosure can be attached is not limited to the electric bicycle 1.

[0055] The up-down direction defined in the embodiment is for convenience, and the up-down direction in the embodiment does not have to be perpendicular when the connector device 2 is in use. Also, the left-right direction is not subject to any restrictions other than the left-right direction in the embodiment.

[0056] The side wall 14 to which the connector device 2 is attached may be a side wall of the head tube 101, the top tube 102, the seat tube 104, the seat stays 105, the chain stays 106, or the bracket 107, instead of the down tube 103. Furthermore, the side wall 14 is not limited to a side wall of a cylindrical portion.

[0057] The shape of the through hole 140 in front view is not limited to a rectangular shape, but may be a circular shape (or an exact circle). In addition, the size of the through hole 140 is not limited.

[0058] The locations in the side wall 14 where the through holes 140 are formed and the number of the through holes 140 are not limited.

[0059] The cap member 6 has an optional configuration and does not necessarily have to be provided in the connector device 2.

[0060] The shape of opening 310 in a front view is not limited to a rectangular shape, and may be a circular shape (or an exact circle). Furthermore, the size of opening 310 is not limited, but it is preferable that opening 310 is smaller than through opening 140 and is included inside through opening 140 in a front view.

[0061] There are no limitations on the shape of the attachment portion 31 (upper portion 311, lower portion 312, left portion 313, right portion 314). The attachment portion 31 does not have to be formed in an annular shape when viewed from the front.

[0062] The locations in the holder 3 where the holder mounting holes 33 are formed and the number of holder mounting holes 33 are not particularly limited, but it is preferable that the locations and number of holder mounting holes 33 be formed corresponding to the side wall mounting portions 142 .

[0063] The main body holding portion 32 does not have to be formed in a rectangular shape when viewed from the inside and outside, and does not have to be formed in a ring shape.

[0064] The positions where the holder metal fitting connecting portions 34 are provided and the number of holder metal fitting connecting portions 34 are not particularly limited.

[0065] The positions where the main body fitting connecting portions 42 are provided and the number of main body fitting connecting portions 42 are not particularly limited.

[0066] The positions at which the metal fitting body connecting portions 51 are provided and the number of metal fitting body connecting portions 51 are not particularly limited.
