Description

[Technical field]

[0001] The present invention relates to a stand for an electric kickboard that is separate from the electric kickboard and supports an electric kickboard whose front wheel has an electric motor built in and can be steered by a handle. [Background technology]

[0002] A kick scooter is a type of vehicle that moves forward by placing one foot on a footrest with front and rear wheels and kicking the road surface with the other foot, and a steering handle is provided at the upper end of a steering shaft with a front wheel at the lower end, and by holding the handle with both hands, it is possible to change the direction of travel as desired. Because the kick scooter itself is compact and portable, it has become very popular in urban areas as an auxiliary means of transportation to replace walking.

[0003] Furthermore, when kick scooters are operated by humans, they place a strain on the human power when traveling long distances, so they have evolved from the original non-powered types to the currently mainstream electric kick scooters, and electric kick scooters have been proposed that obtain propulsion power from an electric motor, such as one front wheel and one rear wheel, or one front wheel and two rear wheels (see, for example, Patent Document 1).

[0004] Kick scooters with one wheel in the front and one wheel in the back cannot stand on their own, so they require a stand to keep them standing, and a sense of balance is required when riding, but because they have two wheels there is less friction with the ground, making it easier to pick up speed and allowing you to enjoy the feeling of riding and speed.In contrast, kick scooters with one wheel in the front and two wheels in the back have three wheels, making them more stable and comfortable to ride, and they can be ridden steadily even on rough roads.

[0005] Electric kick scooters are typically configured to use power stored in a battery installed on the scooter to drive the front wheel, which has an electric motor built in, and this battery needs to be charged during use.

[0006] For example, the most common charging method for electric bicycles currently in practical use is the conductive charging method, in which electrical energy is exchanged by electrically connecting the charging connector of the charger with the connector of the secondary battery. With this method, the battery pack containing the secondary battery is removed from the bicycle body and carried close to an indoor charging device, where it is charged. For this reason, the secondary battery is designed to be easily removed from the bicycle body, reducing the workload required for charging (see, for example, Patent Document 2).

[0007] Furthermore, in order to charge a battery mounted on a bicycle, it is quite time-consuming to remove the battery from the bicycle and set it on a charging device, and to connect the charging terminal of the battery mounted on the bicycle to the output terminal of the charging device with a long cable. To eliminate this inconvenience, a power supply system for electric bicycles has been proposed in which, simply by erecting a support stand for the bicycle parked in a bicycle parking lot, electricity is supplied to the bicycle through electromagnetic induction, thereby charging the bicycle battery (see, for example, Patent Documents 3 and 4).

[0009] Like electric bicycles, electric kickboards are compact and portable, but their on-board batteries still need to be charged, and there is a demand for the ability to charge the batteries while the kickboard is in storage.

[0010] In view of the conventional situation as described above, the object of the present invention is to provide an electric kickboard stand that is separate from the electric kickboard and supports an electric kickboard whose front wheel has an electric motor built in and can be steered by a handle, allowing the user to easily store the kickboard body and charge the battery while in storage.

[0011] Other objects of the present invention and specific advantages obtained by the present invention will become more apparent from the following description of the embodiments. [Means for solving the problem]

[0012] That is, the present invention provides a stand for an electric kickboard that is separate from an electric kickboard and supports an electric kickboard whose front wheel has an electric motor built in and can be steered by a handle, the electric kickboard comprises a battery that supplies power to the electric motor and a power receiving unit for charging the battery when attached to the electric kickboard, and the stand base comprises a pole erected on a mounting platform on which the front wheel of the electric kickboard is placed, a grip holder that is freely raised and lowered on the upper end side of the pole and supports one end of the handle of the electric kickboard when the front wheel is placed on the mounting platform, and a power transmission unit that is detachably held by a power transmission unit holder provided on the upper end side of the pole, The stand base supports one end of the handle of the electric kickboard, whose front wheel is placed on the mounting stand, with the grip holder, thereby keeping the electric kickboard in a stationary state, and in this state, the power transmission unit is removed from the power transmission unit holder and attached to the power receiving unit of the electric kickboard, thereby having a charging function of charging the battery of the electric kickboard via the power transmission unit and power receiving unit.

[0013] In the electric kickboard stand according to the present invention, the pole may be supported at its base end by a hinge mechanism, allowing the pole to change position from an upright position to a lying position.

[0014] In addition, in the electric kickboard stand of the present invention, the hinge mechanism can support the base end of the pole so that it can rotate freely in a direction that changes the position of the pole from an upright position to a lying position, and so that it can slide freely in the direction of its rotation axis.

[0015] Furthermore, in the electric kickboard stand according to the present invention, the power transmitting unit and the power receiving unit may perform contactless power supply.

[0016] In addition, the stand for an electric kickboard according to the present invention comprises a base frame that supports the stand base so that it can be moved freely in one direction, and when the stand base supported by the base frame so that it can be moved freely in one direction is positioned at the rear end position, it prohibits movement of the stand base, and is equipped with an unlocking mechanism that releases the prohibition on movement of the stand base by detecting that the front wheel of the electric kickboard placed on the mounting stand is in a predetermined position in this state, and the unlocked stand base is moved to the front end position of the base frame with one end of the handle of the electric kickboard supported by the grip holder, and the battery of the electric kickboard is charged at the front end position of the base frame via the power transmitting unit and the power receiving unit.

[0017] In addition, in the electric kickboard stand of the present invention, the lock release mechanism can release the prohibition on movement of the stand base by detecting that the handle of the electric kickboard placed on the mounting base is rotated and the front wheel is in a predetermined tilted position.

[0018] In addition, in the electric kickboard stand of the present invention, the pole erected on the mounting base has its base end rotatably arranged around an axis of rotation perpendicular to the direction of movement of the base frame, and can be tilted toward the rear end of the base frame at the front end position of the base frame.

[0019] Furthermore, in the electric kickboard stand of the present invention, the pole erected on the mounting base has its base end rotatably arranged around an axis of rotation perpendicular to the direction of movement of the base frame, and can be tilted toward the front end of the base frame at the rear end position of the base frame. Effect of the Invention

[0020] In the present invention, a stand base comprising a pole erected on a mounting platform on which the front wheel of an electric kickboard is placed, a grip holder that is freely raised and lowered on the upper end side of the pole and supports one end of the handle of the electric kickboard with the front wheel placed on the mounting platform, and a power transmission unit that is detachably held by a power transmission unit holder provided on the upper end side of the pole supports one end of the handle of the electric kickboard with the front wheel placed on the mounting platform by the grip holder, keeping the electric kickboard in a stationary state, and in this state, the power transmission unit removed from the power transmission unit holder is attached to the power receiving unit of the electric kickboard, thereby having a charging function of charging the battery of the electric kickboard via the power transmission unit and the power receiving unit.Therefore, the electric kickboard can be stored in a state in which the front wheel with an built-in electric motor supports it and the battery of the electric kickboard during storage can be charged via the power transmission unit and the power receiving unit.

[0021] Therefore, according to the present invention, it is possible to provide an electric kickboard stand that is separate from the electric kickboard and supports an electric kickboard whose front wheel has an electric motor built in and can be steered by a handle, allowing the user to easily store the kickboard itself and charging the battery of the electric kickboard while in storage.

FIG. 5 is a diagram showing a schematic configuration of a charging circuit for the battery 50 by power supply from the power transmission unit 141 attached to the power receiving unit 40 of the electric kickboard 1. FIG. 6 is an external perspective view showing the electric kickboard stand 100 with the pole 120, the base end of which is supported by the hinge mechanism 160, in a lying position.

[0025] This electric kickboard stand 100 is an electric kickboard stand separate from the electric kickboard 1, and supports an electric kickboard 1 whose front wheel 31, which has an internal electric motor, can be steered by a handlebar 22. As shown in Figures 1, 2, and 3, the stand consists of a pole 120 erected on a mounting stand 110 on which the front wheel 31 of the electric kickboard 1 is placed, a grip holder 130 which is freely raised and lowered on the upper end side of the pole 120 and supports one end of the handlebar 21 of the electric kickboard 1 when the front wheel 31 is placed on the mounting stand 110, and a power transmission unit 141 which is detachably held by a power transmission unit holder 140 provided on the upper end side of the pole 120.

[0026] As shown in Figures 3, 4 and 5, the stand base 150 supports one end of the handle 21 of the electric kickboard 1, whose front wheel 31 is placed on the mounting stand 110, using the grip holder 130 to keep the electric kickboard 1 stationary, and in this state, the power transmission unit 141 removed from the power transmission unit holder 140 is attached to the power receiving unit 40 of the electric kickboard 1, thereby having a charging function of charging the battery 50 of the electric kickboard 1 via the power transmission unit 141 and the power receiving unit 40.

[0027] As shown in Figure 3, the electric kickboard 1 is an electric kickboard in which a front wheel 31 equipped with an electric motor can be steered by a handlebar 21, and has a handlebar shaft 20 that is inserted and held in the front frame 11 of the frame body 10 and has the handlebar 21 attached to its upper end side, and a front wheel track 30 is attached to an attachment frame 22 attached to the lower end side of the handlebar shaft 20, and has a front wheel support frame 32 that supports the front wheel 31 so that it can rotate freely.

[0028] The front wheel support frame 32 of the front wheel track 30 is attached to the rear end side of the mounting frame 22 via a support shaft 33 arranged parallel to the rotation axis of the front wheel 31 so as to be freely rotatable in the axial direction, and is supported by a pair of front suspensions 34 so as to be freely resiliently displaced in the axial direction of the handle shaft 20.

[0029] The frame body 10 is formed by combining a front frame 11, a board frame 12 and a rear frame 13 into one body, a foot rest board 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] In addition, in this electric kickboard 1, a rear wheel truck 60 having a rear wheel support frame 62 that rotatably supports one rear wheel 61 by a pair of bearing portions is attached to the underside of the rear frame 13 of the frame body 10.

[0031] The rear wheel support frame 62 of the rear wheel track 60 is attached to the front end side of the rear frame 13, to which the board frame 12 and rear frame 13 are connected, so as to be freely rotatable in the axial direction via a support shaft arranged parallel to the rotation shaft 63 of the rear wheel 61, and is supported by a rear suspension 64 from the upper side of the rear frame 13 so as to be freely displaced elastically downward.

[0032] In this electric kickboard 1, the handlebar 21 for steering the front wheel 31 is made up of a handlebar attached to the upper end of the handle shaft 20 so as to be perpendicular to the axial direction of the handle shaft 20, and as shown in Fig. 3, left and right grip parts 23L, 23R and brake levers 24L, 24R are provided on both ends of the handlebar, and further, a power supply voltage display part 25 is provided. The right grip part 23 functions as an accelerator that controls the number of revolutions of the electric motor built into the front wheel 31 by controlling the power supplied from the battery 50 to the electric motor. In addition, the left brake lever 24L operates the front wheel brake, and the right brake lever 24R operates the rear wheel brake.

[0033] This electric kickboard 1 can be driven by the rider standing on one foot on the footrest 35 and kicking the ground with the other leg. The front wheel 31, which can be steered using the handlebars 21, is driven and rotated by an electric motor built into it, making the scooter self-propelled. By operating the right grip section 23R, which functions as an accelerator that controls the rotation speed of the electric motor, the speed can be increased or decreased, allowing the scooter to be steered according to the rider's purpose.

[0034] In addition, this electric kickboard 1 is a two-wheeled vehicle with a front wheel 31 and a rear wheel 61, and since it cannot stand on its own when stationary, it can be made to stand on its own when stationary by landing on a side stand 80 provided on the side of the board frame 12.

[0035] In this electric kickboard 1, a power receiving unit 40 for charging the battery 50 is attached to a power receiving unit holder 41 provided in the middle part of the front frame 11, as shown in FIG.

[0036] This electric kickboard stand 100 includes a power transmission unit 141 that is attached to the power receiving unit 40 to charge the battery 50.

[0037] The power transmission unit 141 provided in this electric kickboard stand 100 is detachably held by a power transmission unit holder 140 provided on the upper end side of a pole 120 erected on the electric kickboard stand 100, as shown in (A) of Figure 4.

[0038] The power transmission unit 141 has a pair of locking arms 142 on both side panels for removing it from the power transmission unit holder 140 and attaching it to the power receiving unit 40 of the electric kickboard 1, and an L-shaped connecting bracket 145 to which a connecting screw 143 is fixed by a nut 144 is provided on the top plate.

[0039] In addition, the power receiving unit 40 has a locking shaft 42 on both side plates for locking the pair of locking arms 142 provided on the power transmitting unit 141, and an L-shaped connecting fitting 43 connected to a connecting screw 143 fixed to the L-shaped connecting fitting 145 is provided on the top plate.

[0040] Then, the power transmission unit 141 removed from the power transmission unit holder 140 is securely attached to the power receiving unit 40 of the electric kickboard 1 by threading the connecting screw 143 with the pair of locking arms 142 locked to the locking shaft 42, as shown in Figure 4 (B) , so that the L-shaped connecting fitting 145 and the L-shaped connecting fitting 43 are connected and fixed via the connecting screw 143.

[0041] In this electric kickboard stand 100, the configuration of a charging circuit for the battery 50 fed with power from a power transmission unit 141 attached to the power receiving unit 40 of the electric kickboard 1 is shown in Fig. 5, as a schematic diagram. The power transmission unit 141 includes a power supply circuit 141A that converts power supplied from a power source into AC power of an amplitude and frequency suitable for contactless power supply, and a power transmission coil 141B to which the AC power obtained by the power supply circuit 141A is supplied. The power transmission coil 141B is a coil element for contactlessly supplying power to the power receiving coil 40A. Specifically, the power transmission coil 141B transmits 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 kickboard 1 in a contactless manner.

[0042] The power receiving unit 40 on the electric kickboard 1 side includes a power receiving coil 40A to which AC power is contactlessly supplied from a power transmitting unit 141 on the electric kickboard 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 electric kickboard stand 100, the power transmission unit 141 is held in a detachable manner 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 kickboard 1, the battery 50 of the electric kickboard 1 can be charged via the power transmission unit 141 and the power receiving unit 40.

[0044] The electric kickboard stand 100 includes a pole 120 erected on a mounting stand 110 on which the front wheel 31 of the electric kickboard 1 is placed, a grip holder 130 that is freely raised and lowered on the upper end side of the pole 120 and supports one end of the handle 21 of the electric kickboard 1 with the front wheel 31 placed on the mounting stand 120, and a power transmission unit 141 that is detachably held by a power transmission unit holder 140 provided on the upper end side of the pole 120.The stand base 150 supports one end of the handle 21 of the electric kickboard 1 with its front wheel 31 placed on the mounting stand 110 by the grip holder 130, allowing the electric kickboard 1 to be stored in a stationary state. Then, with the electric kickboard 1 stationary, the power transmission unit 141 is removed from the power transmission unit holder 140 and attached to the power receiving unit 40 of the electric kickboard 1, thereby allowing the battery 50 of the electric kickboard 1 to 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 the slide pole 121 inserted into the pole 120. The height position can be adjusted by extending and contracting the slide pole 121, and the posture can be changed by rotating the slide pole 121.

[0046] In other words, the electric kickboard stand 100 allows the electric kickboard 1, which can be steered by the handlebars 21, to be stored in a supported state with the front wheel 31 having an electric motor built in, and allows the battery 50 of the electric kickboard 1 to be charged via the power transmission unit 141 and the power receiving unit 40 during storage.

[0047] In this electric kickboard stand 100, the grip holder 130 that supports one end of the handle 21 of the electric kickboard 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] In addition, as shown in Figures 1, 2 and 6, a handle portion 170 is provided on the front side of the mounting stand 110, and the electric kickboard stand 100 can be freely transported by grasping this handle portion 170, and the user can transport and set up the electric kickboard stand 100 to a storage location for the electric kickboard 1 they own.

[0049] 1 and 6, in the electric kickboard stand 100, a slope 111 and a guide groove 112 for the electric kickboard 1 to climb up are provided on the mounting base 110, and the pole 120 is supported at its base end by a hinge mechanism 160 whose rotation axis direction is perpendicular to the guide groove 112, allowing the pole to change position from an upright position to a lying position. Fig. 6 shows the pole 120 in the lying position in the electric kickboard stand 100, with its base end supported by the hinge mechanism 160.

[0050] The hinge mechanism 160 supports the base end of the pole 120 so as to be rotatable in a direction for changing the posture of the pole 120 from an upright position to a lying position, and so as to be slidable in the direction of the axis of rotation.

[0051] In the electric kickboard stand 100, the base end of the pole 120 is supported by a hinge mechanism 160 whose rotation axis direction is perpendicular to the guide groove 112. However, as in the electric kickboard stand 100A shown in Figures 7, 8, and 9, the pole 120 may be supported by a hinge mechanism 160A whose base end direction is parallel to the guide groove 112.

Fig. 8 is an external perspective view showing a state in which an electric kickboard 1 is held by the electric kickboard stand 100A. Fig. 9 is an external perspective view showing a state in which the pole 120, the base end of which is supported by the hinge mechanism 160A, is in a lying position in the electric kickboard stand 100A.

[0053] In this electric kickboard stand 100A, the components other than the hinge mechanism 160A that supports the base end of the pole 120 are the same as those in the electric kickboard stand 100, so they are shown with the same reference numerals in the drawings and detailed explanations are omitted.

[0054] Here, the electric kickboard stand 100, 100A is used by fixing the stand base 150 in a storage location for the electric kickboard 1, but it is also possible to install a base frame in the storage location for the electric kickboard 1 and support it so that it can be moved freely in one direction by the base frame.

[0059] The mounting platform 110' in this stand base 150' is provided with a guide wall 113 that guides the front wheel 31 of the electric kickboard 1 that is mounted on the slope 111 to a forward position, and a detection mechanism is provided that detects that the front wheel 31 is in a predetermined position by rotating the handle 21 of the electric kickboard 1 mounted on the mounting platform 110 and tilting it when the front wheel 31 guided by the guide wall 113 abuts against a detection plate 116.

[0060] The base frame 200 includes two guide rails 220A, 220B that are held parallel to each other by three support frames 210A, 210B, 210C that are arranged parallel to each other.

[0061] As shown in FIG. 11, the base frame 200 supports the stand base 150' so that it can move freely in one direction along the two guide rails 220A, 220B by mounting the stand base 150' on the underside of the mounting table 110' so that a plurality of rollers 115 are placed on the two guide rails 220A, 220B.

[0062] In the electric kickboard stand 100B, the electric kickboard 3 is placed on the mounting base 110' in a rear end position on the stand base 150' supported by the base frame 200 so as to be movable in one direction, as shown in Fig. 12. Then, as shown in Fig. 13, one end of the handle 21 is supported by the grip holder 130 with the handle 21 of the electric kickboard 1 placed on the mounting base 110' rotated to tilt the front wheel.

[0063] This base frame 200 is equipped with a lock release mechanism which prevents movement of the stand base 150' by engaging a lock arm 206 with locking sections 205A, 205B provided at predetermined positions on the front and rear sides of the guide rail 220A, and releases the prohibition on movement of the stand base 150' by pivoting the lock arm 206 in conjunction with the operation of a detection mechanism which detects that the front wheel 31 of the electric kickboard 1 placed on the mounting stand 110 is in a predetermined position.

[0064] This lock release mechanism releases the prohibition on movement of the stand base 150' by detecting that the detection mechanism is in a predetermined position where the handle 21 of the electric kickboard 1 placed on the mounting stand 110 has been rotated and the front wheel 31 has been tilted.

[0065] In this electric kickboard stand 100B, 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 kickboard 1 supported by the grip holder 130, and the electric kickboard 1 can be stored in a stationary state at the front end position of the base frame 200, as shown in Figure 14.

[0066] In addition, the battery 50 of the electric kickboard 1 can be charged via the power transmitting unit 141 and the power receiving unit 40 at the front end position of the base frame 200.

[0067] In other words, the stand base 150' having a power transmission unit 141 held in a removable manner by a 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 receiving unit 40 by removing the power transmission unit 141 from the power transmission unit holder 140 and attaching it to the power receiving unit 40 of the electric kickboard 1 while the electric kickboard 1 is stationary.

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

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

[0070] The power receiving unit 40 for charging the battery 50 provided on the electric kickboard 1 is attached to the middle part of the front frame 11, but the power receiving unit 40 may be attached anywhere on the frame body 10 formed by combining the front frame 11, the board frame 12 and the rear frame 13 into one unit.

[0071] Here, the stand base 150' in this electric kickboard stand 100B is removably attached to the base frame 200, and in the stand base 150 in the electric kickboard stand 100, similar to the stand base 150', by arranging a plurality of rollers 115 on the underside of the mounting platform 110, it can be removably attached to the base frame 200 in place of the stand base 150', for example, as in the electric kickboard stand 100C shown in Figures 16 and 17.

[0072] FIG. 16 is a side view of an electric kickboard stand 100C in which a stand base 150C showing yet another embodiment of the present invention is supported by a base frame 200 so as to be freely movable in one direction, and FIG. 17 is a plan view of the electric kickboard stand 100C.

[0073] In this electric kickboard stand 100C, the same components as those in the electric kickboard stand 100B are indicated by the same reference numerals in the drawings, and detailed description thereof will be omitted.

[0074] This electric kickboard stand 100C has a stand base 150C with multiple rollers 115 arranged on the underside of the mounting base 110 of the electric kickboard stand 100, and this stand base 150C is removably attached to the base frame 200 of the electric kickboard stand 100B, so that the stand base 150C can move in one direction on the base frame 200.

[0075] In addition, the stand 110 is provided with a slope 111 and a guide groove 112 for the electric kickboard 1 to climb up, and the pole 120 is supported by a hinge mechanism 160 whose base end has a rotation axis direction perpendicular to the guide groove 112, allowing the pole to change its position from an upright position to a lying position.

[0076] In addition, on the rear side of the hinge mechanism 160, a position regulating shaft 180 having a detection plate 116 against which the front wheel 31 of the electric kickboard 1 which is moved along the guide groove 112 abuts is provided on the mounting base 110 so as to be perpendicular to the guide groove 112.

[0077] When the front wheel 31 comes into contact with the detection plate 116 provided on the position restriction shaft 180, the detection plate 116 rotates together with the position restriction shaft 180, with the position restriction shaft 180 serving as a rotation axis.

[0078] The position control shaft 180 is provided with a torsion coil spring (not shown), and when the detection plate 116 is pressed by the front wheel 31, the position control shaft 180 rotates together with the detection plate 116 in the axial direction against the elastic force of the torsion coil spring, and when the pressing force applied to the detection plate 116 is removed, the position control shaft 180 returns to its original position due to the elastic force of the torsion coil spring.

[0079] A lock arm 206 is provided at one end of the position regulating shaft 180, which engages with lock openings 205A, 205B provided at predetermined positions on the front and rear sides of the guide rail 220A to prohibit movement of the stand base 150'.

[0080] The position control shaft 180, which rotates in the axial direction together with the detection plate 116, functions as a detection mechanism that detects that the front wheel 31 of the electric kickboard 1, which has climbed up onto the mounting stand 110 provided on the stand base 150C via a slope 111, is advanced along the guide groove 112 and abuts against the detection plate 116 at the rear end position of the base frame 200, and is placed in a predetermined position on the mounting stand 110 without tilting.The position control shaft 180 also functions as a lock release mechanism that prevents the stand base 150' from moving by engaging a lock arm 206 provided at one end of the position control shaft 180 with lock openings 205A, 205B provided at predetermined positions on the front and rear sides of the guide rail 220A, and prevents the stand base 150' from moving.By rotating in the axial direction together with the detection plate 116, the lock arm 206 pivots and releases the prohibition on movement of the stand base 150'.

[0081] In addition, in this electric kickboard stand 100C, the pole 120 erected on the mounting stand 110 is supported by a hinge mechanism 160 provided on the mounting stand 110 so that its base end can rotate freely around a rotation axis perpendicular to the movement direction of the base frame 200, as shown in FIG. 16, and is supported so as to be movable freely in the direction of the rotation axis, as shown in FIG. 17.

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

[0083] This electric kickboard stand 100C has a pole 120 erected on the stand 110, which is fixed to the fixed part 250 by the fixed plate 251 in a position in which the pole 120 is leaned down toward the front end side of the base frame 200. Therefore, the fixed pole 120 can be grasped as the handle part 170A and lifted in a balanced manner, and can be freely transported.

[0084] As described above, the electric kickboard stand 100C is equipped with a detection mechanism which detects that the front wheel 31 of the electric kickboard 1, which has climbed up onto the mounting platform 110 provided on the stand base 150C via the slope 111 at the rear end position of the base frame 200, is moved along the guide groove 112 and comes into contact with the detection plate 116, thereby detecting that the front wheel 31 has been placed in a predetermined position on the mounting platform 110 without tilting.

[0085] In addition, the guide rail 220A is provided with a locking opening 205A, 205B at predetermined positions on the front and rear sides thereof, thereby engaging a locking arm 206 to prohibit movement of the stand base 150', and the locking arm 206 pivots in response to the operation of a detection mechanism which detects that the front wheel 31 of the electric kickboard 1 placed on the mounting stand 110 is in a predetermined position, thereby releasing the prohibition on movement of the stand base 150'.

[0086] Furthermore, a lock pin 124 for prohibiting the slide pole 121 inserted into the pole 120 from extending or retracting is provided at a position above the pole 120.

[0087] The lock release mechanism operates in conjunction with the operation of a detection mechanism which detects that the front wheel 31 of the electric kickboard 1 placed on the mounting stand 110 is in a predetermined position. Therefore, when transporting the electric kickboard stand 100C, movement of the base frame 200 in the fore-and-aft direction of the base frame 200 is prohibited, and the lock pin 124 can prohibit extension and retraction of the slide pole 121 inserted into the pole 120 which is in a tilted position toward the front end of the base frame 200.

[0088] In this way, this electric kickboard stand 100C can prohibit the movement of the base frame 200 and the extension and retraction of the slide pole 121, so that it can be safely transported even when loaded onto a car.

[0089] Next, Figures 18(A) and (B) are figures used to explain the movement operation of the pole 120 supported by the hinge mechanism 160, where (A) is an external oblique view of the front part of the electric kickboard stand 100C showing a state in which the pole 120 is in a lying position and the base end of the pole 120 is supported by the hinge mechanism 160, and (B) is an external oblique view of the front part of the electric kickboard stand 100C showing a state in which the pole 120 is in an upright position and the base end of the pole 120 is supported by the hinge mechanism 160.

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

[0091] The pair of flange portions 161A, 161B are formed with openings through which the base ends of the poles 120 are inserted, and synthetic resin guide plates 163A, 163B having openings with a diameter slightly larger than the outer diameter of the base ends of the poles 120 are provided adjacent to the flange portions 161A, 161B.

[0092] The pair of flanges 161A, 161B rotatably support the pole 120, the base end of which is inserted through the opening, about a rotation axis perpendicular to the moving direction of the base frame, and also movably support the pole 120 in the direction of the rotation axis. The guide plates 163A, 163B made of synthetic resin provided in association with the pair of flanges 161A, 161B function as protective members for preventing the outer peripheral surface of the base end of the pole 120 from being damaged when the pole 120 supported by the hinge mechanism 160 is moved.

[0093] At the base end of the pole 120 supported by the pair of flange portions 161A, 161B, position control bolts 125A, 125B are erected at the middle portion of the pair of flange portions 161A, 161B and at the tip portion passing through flange portion 161B, with their axial directions differing by approximately 90° and inserted into synthetic resin collars 126A, 126B, respectively.

[0094] The position-regulating bolt 125A provided at the middle of the pair of flanges 161A, 161B comes into contact with the pair of flanges 161A, 161B as the pole 120 moves in the rotation axis direction, thereby regulating the range of movement of the pole 120 in the rotation axis direction. In addition, the position-regulating bolt 125A regulates the angle at which the pole 120 falls toward the front end side of the base frame 200 as a collar 126A comes into contact with a guide edge 162A of a guide portion 162 provided in the hinge mechanism 160.

[0095] Further, a position regulating bolt 125B provided at the tip portion of the base end portion of the pole 120 regulates the angle at which the pole 120 falls toward the rear end side of the base frame 200.

[0096] Next, a grip holder 130C that is provided on the electric kickboard stand 100C and has a structure for clamping one end of the handle of the electric kickboard will be described.

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

[0098] As shown in (A) of Figure 19, the clip holder 130C is a forceps-like holder having a clamping portion 132 at its tip end, which consists of two clamping surfaces 132A, 132B that can be opened and closed by rotating around a support shaft 131. By closing the two handle portions 133A, 133B at the rear end, the two clamping surfaces 132A, 132B open, and by opening the two handle portions 133A, 133B, the two clamping surfaces 132A, 132B close, so that one end of the handle 21 is clamped by the two curved clamping surfaces 132A, 132B.

[0099] This clip holder 130C is equipped with a link mechanism in which link plates 134A, 134B, one end of which is pivoted by pivots 133a, 133b provided on the two handle portions 133A, 133B, are connected at the other end by an operating shaft 135. By pushing the operating shaft 135 of the grip holder 130C, which shows the clamping portion 132 in an expanded state as shown in FIG. 20(A), and moving it forward, the clamping portion 132 can be closed as shown in FIG. 20(B). Also, by pulling the operating shaft 135 of the grip holder 130C with the clamping portion 132 closed and moving it backward, the clamping portion 132 can be opened as shown in FIG. 20(A).

[0100] Moreover, as shown in Figures 19(A), (B), and (C), this clip holder 130C is equipped with a locking mechanism 136 that prohibits the movement of the operating shaft 135, i.e., the opening and closing of the clamping part 132. With the clamping part 132 closed, as shown in Figure 19(C), by inserting a key 137 into the keyhole to lock it, the operating shaft 135 can be engaged by a locking plate 136A of the locking mechanism 136, thereby prohibiting movement.

[0101] In this electric kickboard stand 100C, at the rear end position of the base frame 200, the front wheel 31 of the electric kickboard 1 rides up onto the mounting platform 110 provided on the stand base 150C via a slope 111, moves along the guide groove 112 and abuts against the detection plate 116, and the front wheel 31 is placed in a predetermined position on the mounting platform 110 without tilting, thereby releasing the permanent lock of the base frame 200.

[0102] In this electric kickboard stand 100C, as in the case of the electric kickboard stand 100B, one end of the handle 21 of the electric kickboard 1 can be supported by the grip holder 130C and moved to the front end position of the base frame 200, and the electric kickboard 1 can be stored in a stationary state at the front end position of the base frame 200.

[0103] In addition, the battery 50 of the electric kickboard 1 can be charged via the power transmitting unit 141 and the power receiving unit 40 at the front end position of the base frame 200. [Explanation of symbols]
