Description

Technical Field

[0001] The present invention relates to a stand for an electric kick scooter, which is separate from the electric kick scooter and supports the electric kick scooter having a front wheel with a built-in electric motor that can be steered by a handlebar.

Background Art

[0002] A kick scooter is a type of vehicle in which one foot is placed on a footrest provided with a front wheel and a rear wheel, and the vehicle body moves forward by kicking the road surface with the other foot. A steering handle is provided on the upper end side of a handlebar shaft having a front wheel on the lower end side. By gripping the handlebar with both hands, the traveling direction can be arbitrarily changed. Since the kick scooter body is compact and portable, it is very popular in the city center as an auxiliary vehicle instead of walking.

[0003] In addition, in the case of a kick scooter operated by a person, there is a burden on human power during long-distance travel. Therefore, it has evolved from the original non-powered type to the currently mainstream electric kick scooter, and electric kick scooters of the type with a front wheel and a rear wheel or the type with a front wheel and two rear wheels that obtain propulsion force by an electric motor have been proposed (see, for example, Patent Document 1).

[0004] The kick scooter of the type with a front wheel and a rear wheel does not stand on its own, so a stand is required to make it stand on its own, and a sense of balance is required during traveling. However, since it has two wheels, the friction with the ground is small, so it is easy to gain speed, and a riding feeling and a sense of speed can be enjoyed. On the other hand, the kick scooter of the type with a front wheel and two rear wheels has high stability due to having three wheels and can be ridden comfortably, and can be stably driven even on rough roads.

[0005] In an electric kick scooter, it is configured to drive a front wheel with a built-in electric motor by using the electric power stored in a battery usually mounted on the kick scooter, and it is necessary to charge the battery as it is used.

[0006] For example, as a charging method for currently commercialized electric bicycles, a conductive charging method in which electrical energy is transferred by electrically connecting the charging connector of a charger and the connector of a secondary battery is common. In this method, a battery pack containing a secondary battery was removed from the bicycle body, carried near an indoor charging device, and charged there. For this reason, the secondary battery had a structure that could be easily removed from the bicycle body, reducing the work burden for charging (see, for example, Patent Document 2).

[0007] In addition, in order to charge the battery mounted on a bicycle, removing the battery from the bicycle and setting it in a charging device, or connecting the charging terminal of the battery in the mounted state on the bicycle and the output terminal of the charging device with a long cable is quite time-consuming. To eliminate such inconveniences, a power supply system for an electric bicycle has been proposed in which, by simply raising the support stand of a bicycle parked in a parking lot, power is supplied to the bicycle by electromagnetic induction action and the battery of the bicycle is charged (see, for example, Patent Documents 3 and 4).

[0027] As shown in FIG. 3, the electric kick scooter 1 is an electric kick scooter with a front wheel 31 having a built-in electric motor that can be steered by a handle 21. It has a handle shaft 20 that is inserted and gripped by the front frame 11 of the frame body 10, and the handle 21 is attached to the upper end side. A front wheel track 30 having a front wheel support frame 32 that rotatably supports the front wheel 31 on an attachment frame 22 attached to the lower end side of the handle shaft 20 is attached.

[0028] The front wheel support frame 32 of the front wheel track 30 is rotatably attached in the axial rotation direction via a support shaft 33 arranged parallel to the rotation axis of the front wheel 31 on the rear end side of the attachment frame 22, and is elastically displaceable in the axial direction of the handle shaft 20 by a pair of front suspensions 34.

[0029] The frame body 10 is integrated with the front frame 11, the board frame 12, and the rear frame 13 being combined. A footrest plate 35 is attached to the upper side of the board frame 12, and a battery 50 that supplies power to the electric motor is attached to the lower side of the board frame 12.

[0030] Further, this electric kick scooter 1 has a rear wheel track 60 having a rear wheel support frame 62 that rotatably supports a single rear wheel 61 by a pair of bearing portions, and the rear wheel track 60 is attached to the lower side of the rear frame 13 of the frame body 10.

[0040] Then, on the power receiving part 40 of the electric kick scooter 1, with the power transmission part 141 removed from the power transmission part holder 140, as shown in FIG. 4(B), in a state where the pair of locking arms 142 are locked to the locking shafts 42, by screwing in the connecting screw 143, the L-shaped connecting fitting 145 and the L-shaped connecting fitting 43 are connected and fixed via the connecting screw 143 and securely attached.

[0041] In this electric kick scooter stand 100, as schematically shown in Fig. 5 for the configuration of the charging circuit of the battery 50 by power supply from the power transmission unit 141 attached to the power receiving unit 40 of the electric kick scooter 1, the power transmission unit 141 includes a power supply circuit 141A that converts the power supplied from the power source into AC power with an amplitude and frequency suitable for non-contact power supply, and a power transmission coil 141B to which the AC power obtained by this power supply circuit 141A is supplied. The power transmission coil 141B is a coil element for performing non-contact power supply to the power receiving coil 40A. Specifically, the power transmission coil 141B transmits the AC power output from the power supply circuit 141A to the power receiving coil 40A provided in the power receiving unit 40 of the electric kick scooter 1 in a non-contact manner.

[0042] The power receiving unit 40 on the electric kick scooter 1 side includes a power receiving coil 40A that receives non-contact power supply of AC power from the power transmission unit 141 on the electric kick scooter stand 100 side, and a charging circuit 40B that converts the AC power obtained by the power receiving coil 40A into DC power suitable for charging the battery 50 and charges the battery 50 with the converted DC power.

[0043] In the above electric kick scooter stand 100, the power transmission unit 141 is detachably held by a power transmission unit holder 140 provided on the upper end side of the pole 120, and by removing it from the power transmission unit holder 140 and attaching it to the power receiving unit 40 of the electric kick scooter 1, the battery 50 of the electric kick scooter 1 can be charged via the power transmission unit 141 and the power receiving unit 40.

[0044] In the above-mentioned stand 100 for an electric kick scooter, a pole 120 erected on a mounting table 110 on which the front wheel 31 of the electric kick scooter 1 is placed, a grip holder 130 provided on the upper end side of the pole 120 so as to be vertically movable, and supporting one end of the handle 21 of the electric kick scooter 1 with the front wheel 31 placed on the mounting table 120, and a power transmission unit 141 detachably held by a power transmission unit holder 140 provided on the upper end side of the pole 120 are provided. The stand base 150 can support one end of the handle 21 of the electric kick scooter 1 with the front wheel 31 placed on the mounting table 110 by the grip holder 130 and store the electric kick scooter 1 in a stationary state. Then, by mounting the power transmission unit 141 removed from the power transmission unit holder 140 to the power receiving unit 40 of the electric kick scooter 1 in a stationary state, the battery 50 of the electric kick scooter 1 can be charged via the power transmission unit 141 and the power receiving unit 40.

[0045] The grip holder 130 has a handle cover-like structure into which one end of the handle 21 is inserted, and is provided at the curved tip of a slide pole 121 inserted into the pole 120. By expanding and contracting the slide pole 121, the height position can be adjusted, and by rotating the slide pole 121, the posture can be changed.

[0046] That is, in the above-mentioned stand 100 for an electric kick scooter, the electric kick scooter 1 with a front wheel 31 incorporating an electric motor and steerable by a handle 21 is supported and stored, and the battery 50 of the electric kick scooter 1 during storage can be charged via the power transmission unit 141 and the power receiving unit 40.

[0047] In this stand 100 for an electric kick scooter, the grip holder 130 that supports one end of the handle 21 of the electric kick scooter 1 has a handle cover-like structure into which one end of the handle 21 is inserted, but it may also have a structure that clamps one end of the handle 21.

[0048] Also, as shown in FIGS. 1, 2, and 6, a handle portion 170 is provided on the front side of the mounting table 110. By grasping this handle portion 170, the electric kickboard stand 100 can be freely carried, and the user can carry and install the electric kickboard stand 100 at the storage location of the owned electric kickboard 1.

The lock arm 206 pivots in conjunction with the operation of a detection mechanism that detects that the front wheel 31 of the electric kick scooter 1 placed on the mounting table 110 is in a predetermined position, thereby providing a lock release mechanism for releasing the prohibition of movement of the stand base 150'.

[0064] This lock release mechanism releases the prohibition of movement of the stand base 150' by detecting that the detection mechanism has detected that the handle 21 of the electric kick scooter 1 placed on the mounting table 110 has been rotated to incline the front wheel 31 to a predetermined position.

[0065] In this stand 100B for an electric kick scooter, the unlocked stand base 150' is moved to the front end position of the base frame 200 with one end of the handle 21 of the electric kick scooter 1 supported by the grip holder 130, and as shown in FIG. 14, the electric kick scooter 1 can be stored in a stationary state at the front end position of the base frame 200.

[0066] Also, at the front end position of the base frame 200, the battery 50 of the electric kick scooter 1 can be charged via the power transmission unit 141 and the power reception unit 40.

[0067] That is, the stand base 150’ including the power transmission unit 141 detachably held by the power transmission unit holder 140 provided on the upper end side of the pole 120 can charge the battery 50 of the electric kickboard 1 via the power transmission unit 141 and the power reception unit 40 when the power transmission unit 141 removed from the power transmission unit holder 140 is attached to the power reception unit 40 of the electric kickboard 1 in a state where the electric kickboard 1 is stationary.

[0068] In addition, in this electric kickboard stand 100B, the pole 120 whose base end is supported by the hinge mechanism 160 on the stand base 150’ can be laid down to a lying position by being tilted at a predetermined position behind the two guide rails 220A and 220B as shown in FIG. 11, with the movement of the stand base 150’ prohibited.

[0069] Also, in this electric kickboard stand 100B, since the power reception unit 40 for charging the battery 50 provided in the electric kickboard 1 is attached to the power reception unit holder 41 provided in the middle part of the front frame 11, if a shopping basket or the like is attached to the front frame 11, it may be difficult to attach the power transmission unit 141 removed from the power transmission unit holder 140. Therefore, as shown in FIG. 15, it is attached to the power reception unit holder 41 so that the attachment posture with respect to the front frame 11 can be changed.

[0070] Note that the power reception unit 40 for charging the battery 50 provided in the electric kickboard 1 is attached to the middle part of the front frame 11, but the attachment position of the power reception unit 40 may be anywhere, such as being arranged at any position of the frame body 10 in which the front frame 11, the board frame 12, and the rear frame 13 are coupled and integrated.

[0071] Here, the stand base 150' in this electric kick scooter stand 100B is detachably attached to the base frame 200. Similarly, in the stand base 150 of the electric kick scooter stand 100, by disposing a plurality of rollers 115 on the lower side of the mounting table 110, it can be detachably attached to the base frame 200 instead of the stand base 150', for example, like the electric kick scooter stand 100C shown in FIGS. 16 and 17.

[0072] FIG. 16 is a side view of an electric kick scooter stand 100C in which a stand base 150C showing still another embodiment of the present invention is movably supported in one direction by a base frame 200, and FIG. 17 is a plan view of the electric kick scooter stand 100C.

[0073] In this electric kick scooter stand 100C, the same components as those in the electric kick scooter stand 100B are denoted by the same reference numerals in the drawings, and detailed descriptions thereof are omitted.

[0074] This electric kick scooter stand 100C includes a stand base 150C having a plurality of rollers 115 disposed on the lower side of the mounting table 110 of the electric kick scooter stand 100. The stand base 150C is detachably attached to the base frame 200 of the electric kick scooter stand 100B, and the stand base 150C can move in one direction on the base frame 200.

[0075] Further, the mounting table 110 is provided with a slope 111 and a guide groove 112 for getting on the electric kick scooter 1. The pole 120 is supported by a hinge mechanism 160 having the direction orthogonal to the guide groove 112 as the rotation axis direction at its base end portion, and can change its posture from the standing state to the lying state.

[0076] Further, on the mounting table 110, a position regulating shaft 180 is provided on the rear side of the hinge mechanism 160 so as to be orthogonal to the guide groove 112, and the position regulating shaft 180 is provided with a detection plate 116 against which the front wheel 31 of the electric kickboard 1 advancing along the guide groove 112 abuts.

[0077] The detection plate 116 provided on the position regulating shaft 180 rotates together with the position regulating shaft 180 about the position regulating shaft 180 as a rotation axis when the front wheel 31 abuts thereon.

[0078] A torsion coil spring (not shown) is provided on the position regulating shaft 180. When the detection plate 116 is pushed by the front wheel 31, the position regulating shaft 180 rotates in the axial direction together with the detection plate 116 against the elastic force of the torsion coil spring, and when the pressing force applied to the detection plate 116 disappears, the position regulating shaft 180 returns to its original position by the elastic force of the torsion coil spring.

[0079] A lock arm 206 that prohibits the movement of the stand base 150' by being locked to the locking openings 205A and 205B provided at predetermined positions on the front side and the rear side of the guide rail 220A is provided at one end of the position regulating shaft 180.

[0080] The position regulating shaft 180 that rotates around an axis together with the detection plate 116 functions as a detection mechanism for detecting that the front wheel 31 of the electric kickboard 1 that has climbed onto the mounting table 110 provided on the stand base 150C via the slope 111 is placed at a predetermined position on the mounting table 110 without tilting when the front wheel 31 advances along the guide groove 112 and abuts against the detection plate 116 at the rear end position of the base frame 200. At the same time, the locking arm 206 provided at one end of the position regulating shaft 180 is locked to the locking openings 205A and 205B provided at predetermined positions on the front side and the rear side of the guide rail 220A to prohibit the movement of the stand base 150'. By rotating around an axis together with the detection plate 116, the locking arm 206 pivots and functions as a locking release mechanism for releasing the prohibition of the movement of the stand base 150'.

[0081] Further, in this electric kickboard stand 100C, the pole 120 erected on the mounting table 110 is rotatably supported around a rotation axis orthogonal to the moving direction of the base frame 200 by a hinge mechanism 160 provided on the mounting table 110 as shown in FIG. 16, and is movably supported in the rotation axis direction as shown in FIG. 17.

[0082] Then, the pole 120 whose base end is supported by the hinge mechanism 160 is in a posture of falling toward the front end side of the base frame 200 at the rear end position of the base frame 200, and can be fixed by a fixing plate 251 screwed to a fixing portion 250 provided on the base frame 200 as shown in FIG. 17.

[0083] This electric kickboard stand 100C is fixed to the fixing portion 250 by the fixing plate 251 in a posture where the pole 120 erected on the mounting table 110 falls toward the front end side of the base frame 200. Therefore, it can be lifted up with good balance by grasping the fixed pole 120 as the handle portion 170A and can be carried freely.

[0084] Here, as described above, at the rear end position of the base frame 200, the front wheel 31 of the electric kick scooter 1 that has climbed onto the mounting table 110 provided on the stand base 150C via the slope 111 is advanced along the guide groove 112 and abutted against the detection plate 116, so that the front wheel 31 is placed at a predetermined position on the mounting table 110 without being tilted. It is provided with a detection mechanism for detecting this.

[0085] In addition, the lock arm 206 is locked by the locking openings 205A and 205B provided at predetermined positions on the front side and the rear side of the guide rail 220A to prohibit the movement of the stand base 150'. The lock arm 206 pivots in conjunction with the operation of the detection mechanism for detecting that the front wheel 31 of the electric kick scooter 1 placed on the mounting table 110 is at a predetermined position, thereby providing a lock release mechanism for releasing the prohibition of the movement of the stand base 150'.

[0086] Furthermore, a lock pin 124 for prohibiting the expansion and contraction of the slide pole 121 inserted into the pole 120 is provided above the pole 120.

[0087] Since the lock release mechanism operates in conjunction with the operation of the detection mechanism for detecting that the front wheel 31 of the electric kick scooter 1 placed on the mounting table 110 is at a predetermined position, when transporting the electric kick scooter stand 100C, the movement of the base frame 200 in the front-rear direction of the base frame 200 is prohibited, and the expansion and contraction of the slide pole 121 inserted into the pole 120 in a posture state where the pole 120 has fallen toward the front end side of the base frame 200 can be prohibited by the lock pin 124.

[0088] In this way, since the electric kick scooter stand 100C can prohibit the movement of the base frame 200 and the expansion and contraction of the slide pole 121, it can be safely transported even when mounted on an automobile.

[0089] Next, FIGS. 18(A) and (B) are diagrams for explaining the movement operation of the pole 120 supported by the hinge mechanism 160. FIG. 18(A) is a front external perspective view of the front part of the electric kickboard stand 100C showing a state where the pole 120 is in a lying position and the base end portion of the pole 120 is supported by the hinge mechanism 160. FIG. 18(B) is a front external perspective view of the front part of the electric kickboard stand 100C showing a state where the pole 120 is in a standing position and the base end portion of the pole 120 is supported by the hinge mechanism 160.

[0090] The hinge mechanism 160 includes a pair of flange portions 161A and 161B that are formed by bending a metal plate and are erected parallel to each other, and a guide portion 162 that is curved so as to surround the outer periphery of the base end portion of the pole 120 supported by the pair of flange portions 161A and 161B.

[0091] Openings through which the base end portions of the pole 120 are respectively inserted are formed in the pair of flange portions 161A and 161B, and synthetic resin guide plates 163A and 163B having openings with a diameter slightly larger than the outer diameter of the base end portion of the pole 120 are provided therewith.

[0092] The pair of flange portions 161A and 161B rotatably support the pole 120 whose base end portion is inserted through the opening around a rotation axis orthogonal to the moving direction of the base frame, and also support the pole 120 so as to be movable in the rotation axis direction. The synthetic resin guide plates 163A and 163B provided along with the pair of flange portions 161A and 161B function as protection members for preventing the outer peripheral surface of the base end portion of the pole 120 from being damaged when the pole 120 supported by the hinge mechanism 160 moves.

[0093] At the base end of the pole 120 supported by the pair of flange portions 161A and 161B, bolts 125A and 125B for position regulation are erected such that their axial directions are substantially 90° different from each other, with the bolts inserted through synthetic resin-made collars 126A and 126B, respectively, at an intermediate portion between the pair of flange portions 161A and 161B and at a tip portion that has passed through the flange portion 161B.

[0094] The bolt 125A for position regulation provided at the intermediate portion between the pair of flange portions 161A and 161B abuts against the pair of flange portions 161A and 161B when the pole 120 is moved in the rotational axis direction, defining the movement range of the pole 120 in the rotational axis direction. Further, when the collar 126A abuts against a guide edge 162A of a guide portion 162 provided in the hinge mechanism 160, the bolt 125A for position regulation defines the angle at which the pole 120 falls toward the front end side of the base frame 200.

[0095] Also, the bolt 125B for position regulation provided at the tip portion of the base end of the pole 120 defines the angle at which the pole 120 falls toward the rear end side of the base frame 200.

[0096] Next, a grip holder 130C having a structure for clamping one end of a handle of the electric kickboard provided in the electric kickboard stand 100C will be described.

[0097] Figures (A), (B), and (C) of Fig. 19 are diagrams showing a structural example of a grip holder 130C having a structure for clamping one end of a handle 21 of the electric kickboard 1 in the above-described electric kickboard stand 100C. (A) is a side view of the grip holder 130C, (B) is a cross-sectional view taken along line XX of the side view of the grip holder 130C as viewed in the arrow direction, and (C) is a side view of the grip holder 130C showing a state where a key 137 is inserted into a keyhole of a lock mechanism 136 provided in the grip holder 130C. Further, Figures (A) and (B) of Fig. 20 are diagrams for explaining the operation of the grip holder 130C having a structure for clamping one end of the handle 21 of the above-described electric kickboard 1. (A) is a side view of the grip holder 130C showing a state where a clamping portion 132 is expanded, and (B) is a side view of the grip holder 130C showing a state where the clamping portion 132 is closed.

[0098] As shown in Fig. 19(A), the clip holder 130C is a tong-shaped holder having a clamping portion 132 at the tip end, which is composed of two clamping surfaces 132A and 132B that can rotate around a support shaft 131 and can be opened and closed. By closing two handle portions 133A and 133B on the rear end side, the two clamping surfaces 132A and 132B open, and by opening the two handle portions 133A and 133B, the two clamping surfaces 132A and 132B close, and the two curved clamping surfaces 132A and 132B clamp one end of the handle 21.

[0099] This clip holder 130C is provided with a link mechanism in which the other ends of link plates 134A and 134B whose one ends are pivotally supported by pivot shafts 133a and 133b provided on the two handle portions 133A and 133B are connected by an operation shaft 135. As shown in Fig. 20(A), by pushing the operation shaft 135 of the grip holder 130C showing a state where the clamping portion 132 is expanded and moving it forward, the clamping portion 132 can be closed as shown in Fig. 20(B). Also, by pulling the operation shaft 135 of the grip holder 130C in a state where the clamping portion 132 is closed and moving it backward, the clamping portion 132 can be opened as shown in Fig. 20(A).

[0100] In addition, as shown in FIGS. 19(A), (B), and (C), this clip holder 130C is provided with a lock mechanism 136 that prohibits the movement of the operation shaft 135, that is, the opening and closing of the clamping portion 132. With the clamping portion 132 in the closed state, as shown in FIG. 19(C), by inserting a key 137 into the keyhole and locking it, the operation shaft 135 can be locked by the lock plate 136A of the lock mechanism 136 to prohibit movement.

[0101] In this electric kick scooter stand 100C, at the rear end position of the base frame 200, the front wheel 31 of the electric kick scooter 1 that has climbed onto the mounting table 110 provided on the stand base 150C via the slope 111 is advanced along the guide groove 112 and abutted against the detection plate 116. By being placed at a predetermined position on the mounting table 110 without tilting the front wheel 31, the permanent lock of the base frame 200 is released.

[0102] And in this electric kick scooter stand 100C, similar to the case of the electric kick scooter stand 100B, with one end of the handle 21 of the electric kick scooter 1 supported by the grip holder 130C, it can be moved to the front end position of the base frame 200 and stored with the electric kick scooter 1 stationary at the front end position of the base frame 200.

[0103] Also, at the front end position of the base frame 200, the battery 50 of the electric kick scooter 1 can be charged via the power transmission unit 141 and the power reception unit 40.
