Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, since a saddle-riding vehicle basically travels in an exposed environment, it is preferable that the power supply terminal is waterproof. The cover described in Patent Document 1 is said to be waterproof by protecting the opening surface of the terminal like an umbrella by snap-fit engagement. Also, in the same document, it is also said that the power supply terminal may be protected by directly inserting a rubber plug into the terminal opening.

[0005] However, with protection by mere snap-fit engagement, water may enter through the gap, and there are limitations in waterproof performance such as water adhering to the terminal when opening the cover. Also, if a rubber plug that may get wet in the rain is directly inserted, there is also a possibility of short-circuiting and breaking due to dust adhering to the rubber plug.

[0006] In view of the above-mentioned problems, the present invention aims to provide a power supply that is compact, has terminals that are less prone to getting dirty, and is highly convenient to use. [Means for solving the problem]

[0007] The present invention, which solves the above problems, is a power supply device comprising a power supply unit for supplying electricity, a covering unit for covering the power supply unit, and a mounting unit for being attached to a column member, wherein the covering unit is provided to be switchable between an open state that exposes the power supply unit and a closed state that covers the power supply unit, and the power supply unit has a power supply terminal which is a terminal for supplying power, and a protruding unit provided on the outside of the power supply terminal and provided to protrude from a surface including the end face of the power supply terminal, and when in the closed state, the covering unit and the protruding unit are connected in a watertight manner via a packing unit, the power supply device, or a saddle vehicle equipped with a power supply device. This configuration allows for a compact design while ensuring watertightness, providing a power supply that is less prone to terminal contamination, and a saddle-type vehicle that allows for easy power supply to electronic devices while riding.

[0008] In a preferred embodiment of the present invention, the protrusion is a surrounding protrusion that encloses the power supply terminal, and the covering portion is provided with a fitting projection that can be fitted into the surrounding protrusion. This configuration makes it possible to maintain watertightness without contact with the power supply terminals, thus providing a power supply that is less prone to terminal contamination.

[0009] In a preferred embodiment of the present invention, the mating projection is provided on the inside of the covering portion, and the packing portion is provided wrapped around the mating projection. This configuration makes it possible to provide a watertight power supply that is easy to use and has a simple design.

[0010] In a preferred embodiment of the present invention, the covering portion slides along the circumferential surface of the housing of the power supply portion to switch between the open state and the closed state. This configuration allows for easy opening and closing through a sliding motion, thereby further enhancing user convenience.

[0011] In a preferred embodiment of the present invention, at least one of the covering portion or the protruding portion is provided with an elastic packing surface that acts as the packing portion. This configuration simplifies the design and allows for a more compact power supply.

[0012] In a preferred embodiment of the present invention, the power supply unit has a light-emitting unit that emits light when the covering unit is in the open state. This configuration makes it easier to supply power to electronic devices even if the power supply section is not visible due to the covering or other obstructions during use, thus increasing convenience. [Effects of the Invention]

Embodiments for Carrying Out the Invention

[0015] Hereinafter, the power feeder according to each embodiment of the present invention will be described with reference to the drawings. The description will detail the configuration of the embodiment, the method of implementation, and other examples in this order. Note that each of the embodiments shown below is an example of the present invention, and the present invention is not limited to the following embodiments. Also, "approximate" in the application documents means that chamfering or rounding is performed on the subsequent shape, and that the elements constituting the shape are deformed or the length is changed within a range that does not impede the purpose of the configuration.

[0016] ≪First Embodiment≫ As shown in FIGS. 1 to 3, the power feeder X includes a power feeding unit 1 that performs power feeding, a covering unit 2 provided so as to cover a part of the power feeding unit 1, a packing unit Q that watertightly connects the power feeding unit 1 and the covering unit 2, a mounting unit 3 for mounting to a column member such as a handle of a straddle vehicle, and a light emitting unit F for emitting light from a part of the power feeding unit 1. Further, the covering unit 2 is capable of moving while rotating and sliding with respect to the power feeding unit 1. In this specification, the state in which the covering unit 2 completely covers the power feeding terminal 12 described later is referred to as the "closed state", and the state in which the covering unit 2 is opened and the power feeding terminal 12 is exposed to the outside is referred to as the "open state". Furthermore, hereinafter, the direction in which the covering unit 2 is provided with respect to the power feeding unit 1 in the open state will be described as the front direction, and the direction in which the mounting unit 3 is provided will be described as the downward direction.

[0017] The power feeding unit 1 has a power feeding housing 11 for storing electronic components inside the power feeding unit 1, a power feeding terminal 12 provided on the end face of the power feeding housing 11 for inserting an electronic device and performing power feeding, and a protruding portion 13 provided in the vicinity of the power feeding terminal 12 and protruding outward.

[0018] The power supply housing 11 is provided in a cylindrical shape with a polygonal cross-section. In the embodiment, the cross-section is a flattened rectangle with chamfered edges, and is provided so as to be longer than the surface having the power supply terminals 12. Furthermore, the power supply housing 11 is integrally formed by injection molding or the like, and its material is preferably a waterproof plastic such as ABS or PE. In addition to the main body portion described above, the power supply housing 11 also has a contact portion 111 and a connecting projection 112.

[0019] As shown in Figure 4, the contact portion 111 is a set of surfaces that are cut out to correspond to the internal shape of the covering portion 2, so that the covering portion 2 can be fitted into it. The contact portion 111 consists of multiple surfaces that surround the power supply housing 11 or the protruding portion 13. These surfaces are provided perpendicular to the protruding direction of the protruding portion 13 and include a first vertical surface 111a located below the power supply terminal 12, second vertical surfaces 111b located on the left and right sides, and a third vertical surface 111c located above. The height of the first vertical surface 111a and the height at which the third vertical surface 111c is provided are approximately the same as the height at which the power supply housing 11 is provided, and the second vertical surface 111b is provided integrally with the power supply housing 11 so as to have a step when viewed from the first vertical surface 111a. The contact portion 111 is further provided with a stepped surface 111d connecting the first vertical surface 111a and the second vertical surface 111b, which facilitates sliding and fitting, and also enhances waterproof performance by making the shape more complex.

[0020] The connecting projection 112 is a cylindrical projection integrally provided on each of the left and right sides of the power supply housing 11, and is located near the third vertical surface 111c and the protruding portion 13. The inner circumferential surface of this projection engages with the connecting hole 213, which will be described later, enabling the covering portion 2 to slide and rotate to engage.

[0021] The power supply terminal 12 is a terminal that charges electronic components when they are plugged in, and in this embodiment, a USB (Universal Serial Bus) port is assumed. The power supply terminal 12 includes a power supply terminal body 121 to which power is actually supplied, an insertion surface 122 which is the end face of the insertion opening of the power supply terminal body 121, and a power supply circuit 123 that supplies power to the power supply terminal body 121. Hereafter, the surface including the insertion surface 122 will be referred to as the terminal surface.

[0022] The power supply terminal body 121 is located behind the insertion surface 122 and has at least one current-carrying section for supplying a positive or negative voltage and one current-carrying section for grounding, and is also provided with a current-carrying section for exchanging information as needed.

[0023] The power supply circuit 123 is a circuit that includes a conductor that supplies a predetermined voltage to the aforementioned energized section, and incorporates a converter, regulator, fuse, etc. (not shown) to adjust the voltage as needed. All of these are built inside the power supply housing 11, and the end of the power supply circuit 123 is connected to the battery of the saddle vehicle. Here, a portion of the power supply circuit 123 is provided protruding from the rear end of the power supply housing 11. Preferably, a removable connection terminal (e.g., an SAE terminal, not shown) is provided in the middle of the protruding portion, allowing the connection to the battery to be changed as needed.

[0024] Furthermore, a portion of the power supply terminal 12 is provided with a light-emitting section F to make the insertion surface 122, which is covered by the insulation portion 2, more visible. The light-emitting section F is incorporated into a portion of the power supply circuit 123 and consists of a light-emitting section body F1 that actually emits light, a resistor F2, and a switch F3 that controls the supply of power to the light-emitting section body F1.

[0025] The light-emitting unit body F1 is a component that emits light when power is applied, selected from the like, such as a light bulb or LED. While it is preferable that the light-emitting unit body F1 be mounted inside the power supply terminal 12 for improved visibility, it may also be provided on the terminal surface near the insertion surface 122. Furthermore, resistor F2 is connected in series with the light-emitting unit body F1, and as shown in Figure 5, the light-emitting unit body F1 and resistor F2 are connected in parallel with the power supply terminal body 121.

[0026] The switch section F3 is provided so as to protrude from the terminal surface and is designed to interrupt the circuit when pressed, and is preferably a so-called break contact tact switch. Electrically, the switch unit F3 is electrically connected to the power supply terminal body 121 and the light-emitting unit body F1 of the power supply circuit 123, and when the covering part 2 is closed, it disconnects the electrical connection of the power supply circuit 123, preventing power consumption when not in use.

[0027] The protruding portion 13 is a component provided so as to protrude from the terminal surface in the vicinity of the power supply terminal body 121, and is provided integrally with the power supply housing 11. In this embodiment, it is formed as a surrounding protruding portion 131 that protrudes so as to surround the end face of the power supply terminal body 121 and the periphery of the switch portion F3.

[0028] The protruding height of the surrounding projection 131 is set to be at least higher than the protruding height of the switch section F3, and is also made to be approximately the same length as or shorter than the length of the connection hole 213, which will be described later, in order to facilitate installation.

[0029] The covering portion 2 is a member provided at the end of the power supply housing 11 for switching between an open state and a closed state, and has a covering portion body 21 that covers the power supply terminal 12 and a fitting projection 22 that abuts against the protruding portion 13 when in the closed state.

[0030] The covering body 21 has an umbrella portion 211 that covers the terminal surface from above when open, side wall portions 212 that protrude downward from the lower surfaces on the left and right sides of the umbrella portion 211, and connection holes 213 provided at predetermined positions on the side wall portions 212 that engage with the connection projections 112.

[0031] The umbrella portion 211 has an external shape that is roughly a pyramidal pyramidal shape, and the lower surface is hollowed out in a roughly rectangular parallelepiped shape, resulting in an overall bowl-shaped component. The shape of the inner circumference of the hollowed-out surface is made to be roughly the same as or slightly larger than the shape of the outer circumference of the surrounding projection 131, and the depth of the hollowing is deeper than that of the projection 13. In this way, the umbrella portion 211 is fitted into the power supply housing 11.

[0032] The side wall portion 212 is a thin plate member that protrudes from the end face of the umbrella portion 211 and is provided so as to face each other in the left-right direction. The width between the two side wall portions 212 is set to be approximately the same as or slightly smaller than the width of the outer circumferential surface of the protruding portion 13. This allows the protruding portion 13 to be firmly fixed in place. The side wall portion 212 is provided such that its protruding ends abut against the first vertical surface 111a, the second vertical surface 111b, and the stepped surface 111d, respectively, thereby improving watertightness. Furthermore, the presence of the stepped surface 111d allows the umbrella portion 211 to be guided to the correct position even with the engagement method of the present invention.

[0033] The connecting hole 213 is an elongated slot located approximately in the center of the side wall portion 212, and is designed to allow the connecting projection 112 to slide on its inside. A step is provided at the end of the elongated slot 213 to temporarily engage the connecting projection 112. The distance from the lower end of the connecting hole 213 to the umbrella portion 211 is set to be longer than the distance from the connecting projection 112 to the end face of the protruding portion 13, thereby allowing rotation around the connecting hole. Furthermore, the distance from the upper end to the lower end of the connection hole 213 is set to be shorter than the height of the interlocking projection 22 and the protruding portion 13, so that the end face of the interlocking projection does not come into contact with the terminal surface when interlocked.

[0034] The interlocking projection 22 has an interlocking projection body 221 that protrudes from the bottom surface of the hollowed-out portion of the umbrella portion 211 and is integrally provided, and a packing portion Q that makes it watertight when the interlocking projection body 221 is interlocked, and is designed to be fitted into the surrounding projection 131.

[0035] The interlocking projection body 221 is a protruding portion smaller than the hollowed-out shape of the umbrella portion 211. Preferably, it is positioned so that the distance from the hollowed-out inner circumferential surface to the outer circumferential surface of the interlocking projection body 221 is always constant. In Figure 5(a), the end face of the umbrella portion 211 and the end face of the mating projection body 221 are positioned on approximately the same plane, making it easier to insert perpendicularly into the gap between the umbrella portion 211 and the mating projection body 221, and thus easier to fit even if there is a packing portion Q. In Figure 5(b), the end face of the interlocking projection body 221 is located closer to the bottom than the end face of the umbrella portion 211, which prevents dirt and other debris from adhering to the end face of the interlocking projection body 221 even when exposed to crosswinds while in the open state.

[0036] The packing portion Q is an elastic, ring-shaped member that is supported and fixed by being wrapped around the outer circumferential surface of the mating projection body 221. In the closed state, the packing portion Q prevents water from flowing into the power supply terminal by simultaneously making watertight contact with the mating projection body 221 and the protrusion 13. In Figure 5(a), the packing portion Q is wrapped around the outer circumference of the mating projection body 221 and its position is maintained by contacting a step extending near the bottom of the mating projection body 221. In Figure 5(b), the packing portion Q is maintained at the bottom surface of the umbrella portion 211, preventing water from entering the power supply housing 11.

[0037] The packing portion Q can be made of any elastic material such as rubber or silicone, as long as it is watertight. Alternatively, the mating projection body 221 or the protruding portion 13 itself may be used as the elastic material, with the contact surface serving as the packing surface. Furthermore, the packing portion Q may be wrapped around the outer circumference of the protruding portion 13.

[0038] The mounting portion 3 is a component connected to the power supply housing 11 and comprises a C-shaped, elastic C-part 31 in side view and a ring-shaped ring portion 32 provided opposite to the outer circumferential surface of the C-part 31. This allows it to be attached to a pillar (bar, etc.) of the saddle vehicle M. Part C 31 is elastic and the width of the notch is smaller than the bar to which it is attached, and the ring part 32 is integrally formed with part C 31 such that its curvature is greater than that of part C 31. On the other hand, the shape of the mounting part 3 can be any way as long as it can be attached to the bar, and is not limited to this.

[0039] The method of implementing the present invention will be described in detail below with reference to Figure 1. The present invention is implemented by a user who attaches a closed-state power supply X to a saddle vehicle M. Furthermore, the implementation method shown below is just one example, and the method of implementation is not limited to this, and the order may be different.

[0040] First, the user attaches the power supply unit X to the saddle vehicle M. More specifically, the user presses the notch in section C 31 against the column (cylindrical bar) of the saddle vehicle M to secure it. At this time, the unit can be more securely fixed by passing a wire or string through the ring section 32. In addition, the user connects the power supply circuit 123 to the battery of the saddle-riding vehicle M. It is preferable to connect using the SAE terminal located in the middle of the power supply circuit 123.

[0041] Next, the user exposes the power supply terminal 12 by opening the covering portion 2. That is, the user slides the covering portion body 21 forward, then rotates it around the lower end of the connection hole 213, and locks it in the connection hole 213 to open it. In this case, the side wall portion 212 supports the protruding portion 13 by sandwiching it, allowing it to be fixed in any position. Also, when it is in the open state, the switch portion F3 is connected, and the light-emitting portion body F1 emits light.

[0042] Finally, the user connects the electronic device they want to power to the power supply terminal. In this case, although the protruding part 13 and the covering part 2 obstruct the view, the light-emitting unit body F1 emits light, making it easier to connect electronic devices. This allows for the use of a compact power supply that is less prone to terminal contamination and offers high convenience in use.

[0043] 《Second Embodiment》 The following description of the power supply X according to the second embodiment of the present invention will be given with reference to Figures 6 and 7. Components similar to those in the first embodiment will be described using the same reference numerals and their explanation will be omitted.

[0044] The power supply unit X comprises a power supply unit 1 that supplies power, a covering unit 2 that covers the power supply terminal 12, a mounting unit 3 for attaching the power supply unit 1 to a column, and a packing unit Q for making the power supply terminal 12 watertight. Furthermore, the power supply unit 1 includes a power supply housing 11, a power supply terminal 12, and a protruding portion 13.

[0045] The power supply housing 11 is a C-shaped component with a hollow interior, and is designed to form a roughly circular disc shape with holes when connected to the mounting portion 3, so that the column material can be fitted into the holes for mounting. Furthermore, the power supply housing 11 is designed to slide with the covering portion 2 fitted in place by the contact portion 111.

[0046] The contact portion 111 is a surface cut into the power supply housing 11, and the depth of the cut is set to be approximately the same as the thickness of the covering portion 2, thereby preventing the side wall portion 212 from protruding to the outside of the power supply housing 11. Furthermore, the connecting projection 112 provided on the contact portion 111 or the protruding portion 13 engages with the connecting hole 213 provided in the covering portion 2, thereby restricting the radial movement of the covering portion 2 while allowing it to move only in the circumferential direction.

[0047] The power supply housing 11 has an end projection 113 that restricts the movement of the circumferentially sliding covering portion 2 when it is in the open state, thereby making the components less prone to breakage. The end projection 113 is provided integrally with the power supply housing 11 and is preferably approximately the same height as the protruding height of the covering portion 2.

[0048] The power supply terminal 12 comprises a power supply terminal body 121, an insertion surface 122, and a power supply circuit 123, and may also be provided with a light-emitting part F. On the outer circumferential surface of the power supply terminal 12, the terminal surface or insertion surface 122 is provided facing radially inward. In this embodiment, two power supply terminals 12 are provided at intervals, but three or more power supply terminals may be provided. The end of the power supply circuit 123 protrudes from the side of the power supply housing 11 and connects to an external battery (not shown).

[0049] The protruding portion 13 is a part that protrudes in the peripheral area of ​​the power supply terminal 12, and includes a surrounding protruding portion 131 that surrounds the power supply terminal 12, and an external protruding portion 132 that protrudes outward from the circumferential outer side of the surrounding protruding portion 131. In this embodiment, the protruding portion 13 is an elastic member that is attached to the gap portion provided in the peripheral edge of the power supply terminal in the power supply housing 11, and its upper surface acts as a packing surface (packing portion Q) that abuts against the covering portion 2. Various methods of attachment may be used, such as fitting or attaching with adhesive.

[0050] The surrounding projection 131 is a protruding portion that rises up to surround the insertion surface 122. The upper surface of the surrounding projection 131 on the side away from the terminal projection 113 is provided to rise gently as it moves away from the terminal projection 113. This makes it possible to move the covering portion 2 to the locking position while sliding, thus increasing convenience. On the other hand, this portion may be provided with a step, which would allow for more reliable watertightness.

[0051] The external projection 132 is a projection that extends from the surrounding projection 131 and rises above the outer circumferential surface of the power supply housing 11. The external projection 132 is provided along the edge closest to the terminal projection 113, thereby restricting the position of the covered portion 2 when it is closed and preventing the part from coming off.

[0052] The covering portion 2 is a thin plate member having a curved shape corresponding to the side circumference of the power supply housing 11. A connecting hole is provided on its inner circumferential surface into which the connecting projection 112 can be fitted, allowing it to slide on the power supply housing 11 from the terminal projection 113 to the position where it contacts the contact portion 111 furthest from the terminal projection 113. The covering portion 2 comprises a covering portion body 21, a limiting projection 23 provided at the end on the side of the terminal projection 113 to limit the sliding position, and a gripping portion 24 for the user to grasp and slide.

[0053] The covering body 21 is a thin plate provided to form a curved surface as described above, and comprises an elastic curved body 214 and a side wall portion 212 that protrudes from the side surface of the curved body 214 at its end.

[0054] The side wall portion 212 is a member that extends radially inward from the side edge of the curved body 214 and is provided to cover the entire protruding portion 13 in cooperation with the curved body 214. Since the radius of curvature of the lower end of the side wall portion 212 is the same as the radius of curvature of the contact portion 111, the covering portion 2 slides on the contact portion 111. The curved body 214 is a thin plate member bent in the longitudinal direction, and its radius of curvature is smaller than that of the power supply housing 11, so the end on the knob side is always biased toward the inner circumference of the power supply housing 11.

[0055] The restricting projection 23 is an L-shaped member in cross-section that protrudes radially inward, and is provided such that the height of the inner projection is approximately the same as the height of the outer projection 132, and the height of the outer projection is approximately the same as the height of the terminal projection 113, thereby restricting its movement by contacting the two members mentioned above.

[0056] The gripping portion 24 is the part that is pinched and slid over the covering portion 2 during use. In this embodiment, it is provided as a projection that protrudes radially outward from the end of the curved body 214 so as to be symmetrical with respect to the limiting projection 23. In this configuration, the length from the limiting projection 23 to the knob portion 24 is shorter than the length from the terminal projection 113 to the point where the power supply terminal extends radially and intersects with the outer surface of the power supply housing 11, thereby allowing for easy attachment of electronic devices.

[0057] The mounting portion 3 is provided to connect to the power supply housing 11 and form a circular hole on its inside. The mounting portion 3 and the power supply housing 11 are provided so that the distance between them during mounting can be adjusted, for example, by screw members, and an elastic sheet can be inserted on the inside to fix them to the column material.

[0058] The method of use of the present invention will be described in detail below. Parts that overlap with the first embodiment will be omitted from the explanation. The present invention is used by a user who uses a power supply X.

[0059] The user attaches the power supply unit X to the saddle vehicle M and opens the insulated part 2. In other words, the user opens the device by pinching the handle 24 and applying force in the direction of the terminal projection 113. In the open state, the inner surface of the curved body 214 locks into place by acting on the external projection 132, which is made of an elastic material and has high frictional force. The user then connects an electronic device to the power supply terminal 12 and uses it.

[0060] In the closed state, the protruding portion 13, which is also the packing portion Q, and the end of the curved body 214, which is biased radially inward, come into contact, thereby making the space in which the power supply terminal 12 is located watertight.

[0061] Third Embodiment The power supply according to the third embodiment will be described in detail below with reference to Figure 8. Since this embodiment is almost identical to the second embodiment, the explanation of parts other than those that differ from the second embodiment will be omitted. Figure 8(a) is a side view of the embodiment, with the dashed line indicating the inner part that is not normally visible, and Figure 8(b) is a schematic cross-sectional view.

[0062] The power supply housing 11 has rail portions 114, which are recesses or holes formed on the side surface along the outer circumferential surface. The rail portions 114 engage with rail projections 215 provided on the inside of the side wall portions 212, thereby allowing the covering portion 2 to slide along the rails.

[0063] The rail portion 114 is provided along the circumferential direction of the power supply housing 11, extending from the vicinity of the protruding portion 13 toward the power supply terminal 12, and is provided so that the power supply terminal 12 is completely exposed when it is in the open state. Furthermore, a continuous recess is provided at the end of the rail section 114 near the protruding portion 13, extending radially inward, allowing the covering portion 2 to slide in this recess as well. The length of this recess is greater than the thickness of the packing portion Q, and the radial extension line when viewed from above intersects with the protruding portion 13.

[0064] The protruding portion 13 is provided with a surrounding protruding portion 131 that encloses the power supply terminal 12. In this embodiment, further protruding portions are provided that enclose the surrounding protruding portion 131, thereby forming multiple steps. Preferably, the corners of the steps are approximately right angles.

[0065] A packing portion Q is attached to the radially inner surface of the curved body 214. In this embodiment, the packing portion Q is designed to be deformable by being pressed. The maximum thickness of the packing portion Q is preferably approximately the same as or slightly longer than the distance from the outer surface of the power supply housing to the curved body 214 in the open state before deformation, thereby allowing it to be held in a predetermined position by the pressing force even in the open state.

[0066] The following describes how the user will use the power supply X according to this embodiment when opening and closing it. When the user changes from the open to the closed position, the covering portion 2 is slid along the rail portion 114, and when it reaches a position directly above the protruding portion 13, the curved body 214 is pressed radially inward to fit the packing portion Q onto the protruding portion 13. In this process, the packing portion Q presses against the corner of the step of the protruding portion 13, causing it to deform and become tightly sealed against the protruding portion 13. The user can then open the power supply unit X from the closed state by performing the reverse operation. [Explanation of Symbols]
