  According to this aspect, the arched handle is attached to the vehicle body frame, and is disposed so as to surround the operator sitting on the seat from the left and right sides to the front. Thus, the operator can sit on the seat with a sense of security that is surrounded and protected by the arched handle.

  In addition, the operator separates the second handle portion, which is shorter than the first handle portion, from the first handle portion and swings around the axis extending in the vehicle width direction with respect to the vehicle body frame, thereby causing the driver to move to the side of the vehicle body. Space for getting on and off can be opened. And even if the second handle part, which is shorter than the first handle part including the top part of the arched handle, is swung around the axis extending in the vehicle width direction, it does not interfere with surrounding pedestrians. Therefore, according to this aspect, the driver can easily get on and off from the side, and electric mobility that does not get in the way of surrounding pedestrians when getting on and off can be provided.

In the above aspect, the handle may be provided so as to be swingable about an axis extending in the vehicle width direction in the vicinity of the axle position of the rear wheel disposed below the seat.
In this way, the handle swings around the vicinity of the axle position of the rear wheel disposed below the seat. Thereby, compared with the case where the handle swings around the same position as the seat or above the seat, the tip of the second handle portion can swing so as to be positioned below. Therefore, when the driver gets on and off, the tip of the second handle part is passed under the driver (for example, below the operator's shoulder) so that the second handle part does not interfere with getting on and off. it can.

In the above aspect, the first handle portion includes a vehicle body side member attached to the vehicle body frame and a front side member including a top portion of the handle, and the front side member is the vehicle body side member. And a connecting member that can swing in the horizontal direction or the vertical direction.
In this way, when the operator gets on and off, in addition to swinging the second handle portion around the axis to facilitate getting on and off from the side, the front side member of the first handle portion is further provided. By swinging in a horizontal direction or a vertical direction, a sufficient space for getting on and off can be secured.

  Moreover, in the said aspect, you may make it the structure provided with the rotation mechanism which makes the said seat rotatable in a horizontal direction. In this way, when the second handle portion is swung around the axis to get on and off from the side, the direction in which the operator rotates the seat in the horizontal direction and is released by the swing of the second handle portion. It is possible to get on and off more easily.

  Further, in this configuration, the rotation mechanism is fixed so that the seat does not rotate when the second handle portion is attached to the first handle portion, and the second handle portion is fixed to the first handle. The seat may be made rotatable in a state separated from the section. By doing so, the seat can be fixed and the seating state can be stabilized when the operator does not get on and off, and the user can easily get on and off when the driver gets on and off.

  In this case, the rotating mechanism is further configured so that the driver faces the direction opened by the swinging of the second handle portion in a state where the second handle portion is separated from the first handle portion. The seat may be rotated in conjunction with the swing of the second handle portion. By doing in this way, the operator can easily get on and off the vehicle by simply moving the second handle portion so that the driver faces the direction opened by the swinging of the second handle portion. be able to.

  According to the present invention, the driver can easily get on and off from the side, and there is an effect that it is possible to provide electric mobility that does not interfere with surrounding pedestrians when getting on and off.

[First Embodiment]
The electric mobility according to the first embodiment of the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 to 3, the electric mobility 1 according to the present embodiment includes a vehicle body frame 2, a driving wheel (rear wheel) 3 and a driven wheel (front wheel) 4 attached to the vehicle body frame 2, A seat 5 and a footrest 6 fixed to the body frame 2, a handle 7 attached to the body frame 2, and a control unit 8 that controls the drive wheels 3 are provided.

As shown in FIG. 2, the drive wheel 3 is a motor built-in type, and the stator of the motor 3b disposed at the center of the tire 3a in the radial direction is fixed to the vehicle body frame 2, and the rotor of the motor 3b is the tire 3a. It is fixed to.
Two drive wheels 3 are provided at intervals in the width direction of the body frame 2. The drive wheels 3 are attached so as to be rotatable around an axle extending horizontally in the width direction of the body frame 2. Each drive wheel 3 is driven independently by a separate motor 3b, and moves forward and backward linearly by matching the rotational speeds on the left and right sides, and changes direction by varying the rotational speeds. Can be done.

  As shown in FIG. 2, the drive wheel 3 is provided with a camber angle so that the width is widest at the contact point of the tire 3a. As a result, the running stability is improved, and the motor 3b built in the drive wheel 3 can be arranged on the inner side in the width direction than the grounding point so that the entire width of the electric mobility 1 can be suppressed.

  The driven wheel 4 is arranged in a central portion in the width direction of the body frame 2 at a position spaced from the driving wheel 3 in the traveling direction. In the present embodiment, the driven wheel 4 is an omnidirectional wheel (for example, an omni wheel or the like as shown in FIG. 4), and is rotatably attached around an axle extending horizontally in the width direction of the body frame 2. Yes. The omnidirectional wheel is a wheel that enables movement in all directions while the axle is fixed to the body frame 2. In FIG. 1 and FIG. 2, the code | symbol 4a is a wheel house.

  Since the omnidirectional wheel fixes the axle, it does not have to be rotated around an axis (for example, a vertical axis) intersecting the axle like a caster, and the installation space of the driven wheel 4 is small as shown in FIG. It has the advantage that it can be done. In the figure, a broken line shows an example of an installation space when a caster is employed. In particular, even if the diameter of the driven wheel 4 is increased in order to easily get over the unevenness of the road surface, it is not necessary to increase the installation space in the width direction, which is effective.

  The seat 5 is disposed above a position close to the drive wheel 3 between the drive wheel 3 and the driven wheel 4. In the present embodiment, the seat 5 is disposed so that the driven wheel 4 side is in front of the operator A in a state where the operator A is seated on the seat 5. The footrest 6 is disposed between the driving wheel 3 and the driven wheel 4 so as to extend in the traveling direction. In the footrest 6, the operator A puts his / her foot so that the toe is directed toward the driven wheel 4 in a sitting state where the operator A is seated.

  In the present embodiment, the handle 7 is provided so as to be swingable about a swing shaft B extending in the vehicle width direction in the vicinity of the axle position of the drive wheel 3. Therefore, the swing axis B is disposed below the seat 5. And the handle | steering-wheel 7 is comprised by the arch type extended so that the vehicle body frame 2 may be crossed in the vehicle width direction from the lower left and right both sides fixed to the rocking | fluctuation shaft B, as FIG. 6 shows.

  The handle 7 includes a left handle portion 7a connected to the vehicle body frame 2 in the vicinity of the left drive wheel 3, and a right handle portion 7b (vehicle body side member) connected to the vehicle body frame 2 in the vicinity of the right drive wheel 3. And an operation part (front side member) 7c. The operating portion 7c has a left end connected to the tip of the left handle portion 7a and a right end connected to the tip of the right handle portion 7b. The operation portion 7 c is disposed on an arched top portion that serves as the swing end of the handle 7.

  The tip of the right handle portion 7b and the right end of the operation portion 7c are connected at a position D so that they cannot be separated, and the left handle portion 7a and the left end of the operation portion 7c are connected at a position C so as to be separable. . In the handle 7, a portion (first handle portion) where the right handle portion 7 b and the operation portion 7 c are connected and a left handle portion 7 a (second handle portion) are detachably connected. . As is clear from FIG. 2, the left handle portion 7 a (second handle portion) is shorter than the portion (first handle portion) including the operation portion 7 c located at the top of the handle 7.

  As a mechanism for detachably connecting the left handle portion 7a and the left end of the operation portion 7c, various connection mechanisms can be employed. For example, a snatch lock (registered trademark) used for a door of an automobile or the like can be used as a coupling mechanism. Specifically, a snatch lock (engagement member) is disposed on the left handle portion 7a, a receiver (engaged member) is disposed on the left end of the operation portion 7c, and they are connected by engaging them. The snatch lock remains connected to the receiver when it is not unlocked by the lever provided on the snatch lock, and can be separated from the receiver when unlocked by the lever.

As shown in FIG. 7, the operation unit 7 c includes a plate 9 a in which both hands of the operator A lightly opened are arranged side by side, and the plate 9 a around two axes (axis lines 9 b and 9 c) orthogonal to each other. And a support mechanism 11 that is supported so as to be swingable.
In the present embodiment, as shown in FIG. 7A, the plate 9 a is formed in a cylindrical shape that covers the support mechanism 11.

As shown in FIG. 7 (b), the support mechanism 11 is swingable around a base member 11a fixed to the handle 7, and an axis 9b fixed to the base member 11a and extending in the front-rear direction. And a second motor 11d which is fixed to the intermediate member 11b and supports the plate 9a so as to be swingable about an axis 9c extending in the left-right direction.
The support mechanism 11 is a general term for mechanisms including the base member 11a, the intermediate member 11b, the first motor 11c, and the second motor 11d described above.

  Each of the first motor 11c and the second motor 11d includes an angle sensor (not shown) that detects the swing angle of the intermediate member 11b with respect to the base member 11a and the swing angle of the plate 9a with respect to the intermediate member 11b. As shown in FIG. 3, the outputs from these angle sensors are sent to the control unit 8, used for controlling the drive wheels 3, and fed back to the first motor 11c and the second motor 11d to be fed to the plate 9a. It is used to generate a reaction force against the force from the pilot A applied to the vehicle.

  Further, the control unit 8 returns the output of the angle sensor 10 provided in the first motor 11c and the second motor 11d to the origin position, that is, the position where the plate 9a is not tilted in any of the front, rear, left and right. The first motor 11c and the second motor 11d are controlled. Thereby, when the operator A releases his / her hand from the plate 9a, the electric mobility 1 is stopped.

  The control unit 8 generates a control signal for controlling the drive wheels 3 based on the swing angle of the plate 9a in the operation unit 7c from the angle sensor 10 provided in the first motor 11c and the second motor 11d, and each drive The wheel 3 is supplied.

Here, control of the electric mobility 1 by the control unit 8 will be described.
When the operator A tilts the plate 9a forward about the axis 9c, the control unit 8 outputs the same drive command signal to the two drive wheels 3. Thereby, the two driving wheels 3 rotate in the same direction at the same speed, and the electric mobility 1 is advanced. Further, the forward speed in this case is adjusted so as to increase as the tilt angle of the plate 9a increases.

  Similarly, when the plate 9a is tilted backward about the axis 9c, the control unit 8 outputs the same drive command signal to the two drive wheels 3 in the opposite direction. . Thereby, the electric mobility 1 moves backward. In this case, the reverse speed is adjusted so as to increase as the tilt angle of the plate 9a increases. However, the reverse speed is controlled to be smaller than the forward speed.

  Further, when the plate 9a is tilted to the left around the axis 9b, the rotational speed of the right drive wheel 3 is faster than the left drive wheel 3 of the operator A, or the left drive wheel 3 and the right drive are driven. The rotation direction of the wheel 3 is controlled to be reversed. Thereby, the electric mobility 1 is steered leftward. Similarly, when the plate 9a is tilted to the right around the axis 9b, the electric mobility 1 is steered rightward.

  Furthermore, when the electric mobility 1 is moving forward and the plate 9a is tilted to the maximum extent around the axis 9c, the control unit 8 performs the emergency stop process in two drive wheels 3 in a short time. The operation is stopped.

  Next, the operation of the handle 7 of the electric mobility 1 when the operator A gets on and off the electric mobility 1 will be described with reference to FIGS. 8 and 9 are side views showing the electric mobility 1 in which the left handle portion 7a is swung upward. FIG. 9 shows the left handle from the connected state (the state shown in FIG. 1) than FIG. The swing angle of the portion 7a is large. 10 and 11 are plan views showing the electric mobility 1 in which the left handle portion 7a is swung upward. FIG. 11 is more swung from the connected state (the state shown in FIG. 6) than FIG. The angle is large.

  When the operator A gets off the electric mobility 1, the left handle portion 7a and the left end of the operation portion 7c are separated. For example, in the case of being connected by a snatch lock (engagement member not shown) provided on the left handle portion 7a, the operator can receive the snatch lock at the left end of the operation portion 7c (a member to be engaged). ) Operate so that By doing so, the left handle portion 7a and the left end of the operation portion 7c are separated. The left handle portion 7a is provided so as to be swingable about a swing axis B extending in the vehicle width direction with respect to the vehicle body frame 2 while being separated from the left end of the operation portion 7c.

  In a state where the left handle portion 7a and the left end of the operation portion 7c are separated, the operator A holds the lower portion of the tip end portion of the left handle portion 7a from the outside with the left hand and pulls it toward the front. Since the left handle portion 7a separated from the operation portion 7c can swing around the swing axis B, the swing angle shown in FIG. When the operator A pulls the position where the left handle portion 7a is held further forward, the left handle portion 7a has the swing angle shown in FIG.

  If the handle 7 is parallel to the ground and the swing angle is 0 °, the swing angle of the left handle portion 7a shown in FIG. 9 is larger than the swing angle of the left handle portion 7a shown in FIG. When the swing angle of the left handle portion 7a reaches the angle shown in FIG. 9, the left handle portion 7a does not exist on the left side of the electric mobility 1, and the left side of the vehicle body is opened as a space for getting on and off. .

10 and 11 correspond to the swing angles shown in FIGS. 8 and 9, respectively. As is clear from FIGS. 10 and 11, as the swing angle of the left handle 7a increases, the left handle 7a does not exist on the left side of the electric mobility 1, and the left side of the vehicle body is used for getting on and off. Open as space.
Further, the left handle portion 7a swings above the electric mobility 1 and in a direction that does not protrude from the vehicle when viewed in plan. Therefore, even if the left handle portion 7a is swung around the swing axis B extending in the vehicle width direction, it does not interfere with surrounding pedestrians.

  In the electric mobility 1 of the present embodiment, the left handle portion 7a having the swing angle shown in FIG. 9 is restricted so as not to swing further rearward of the vehicle (left side in FIG. 9). That is, the swing angle of the left handle portion 7a at the swing angle shown in FIG. 9 does not change even when the operator A tries to pull the left handle portion 7a further forward. Accordingly, the operator A can get off the electric mobility 1 while supporting the left handle portion 7a with a fixed swing angle with the left arm.

  Further, the electric mobility 1 of the present embodiment is a fixing mechanism (not shown) in which the swing angle around the swing axis B of the right handle portion 7b is fixed in a state where the left handle portion 7a is separated from the operation portion 7c. It has. With this fixing mechanism, the right handle portion 7b can swing around the swing axis B when the left handle portion 7a is attached to the operation portion 7c, and in the state where the left handle portion 7a is separated from the operation portion 7c. The swing angle of the right handle portion 7b is fixed.

  By doing in this way, when the pilot A gets on and off, the operation part 7c and the right handle part 7b are fixed, and the pilot A can fix the fixed operation part 7c and the right handle part 7b (first handle part). You can get on and off in a stable manner. Therefore, in the state shown in FIG. 9, the right hand is attached to the operation portion 7c and the right handle portion 7b (first handle portion), and the left arm portion 7a whose swing angle is fixed by the left arm is supported, and the stable getting on and off is performed. can do.

The operation of the electric mobility 1 according to this embodiment configured as described above will be described below.
When traveling using the electric mobility 1 according to the present embodiment, the pilot A places his / her feet on the footrest 6 with his toes facing the driven wheel 4 side and sits on the seat 5. Then, the handle 7 is arranged at the position shown in FIG. As a result, the handle 7 is disposed so as to surround the front from below the left and right sides of the operator A. As a result, the steering wheel 7 covers the front of the pilot A in the traveling direction and can give the pilot A a sense of security that it is protected.

  Further, the operator A separates the left handle portion 7a (second handle portion), which is shorter than the portion (first handle portion) where the right handle portion 7b and the operation portion 7c are connected, from the operation portion 7c, and separates the body frame. 2, the space for getting on and off the side of the vehicle body can be opened. Even if the left handle portion 7a (second handle portion) is swung around the swing axis B extending in the vehicle width direction, it does not interfere with surrounding pedestrians and the like. Therefore, according to the present embodiment, it is possible to provide the electric mobility 1 that can easily get on and off from the side and does not get in the way of surrounding pedestrians when the pilot A gets on and off.

  Further, in the electric mobility 1 of the present embodiment, the handle 7 swings around the vicinity of the axle position of the drive wheel 3 disposed below the seat 5. As a result, as compared with the case where the handle 7 swings around the same position as the seat 5 or above the seat 5, the tip of the left handle portion 7a (second handle portion) swings so as to be positioned below. Therefore, when the pilot A gets on and off, the tip of the left handle 7a (second handle) is passed below the head of the pilot A (for example, below the shoulder of the pilot A) and left The handle portion 7a (second handle portion) can be prevented from getting in the way.

  Further, since the seat 5 is disposed between the driven wheel 4 and the driving wheel 3, the center of gravity of the seated operator A is disposed between the driven wheel 4 and the driving wheel 3, and the driven wheel 4 and the driving wheel are arranged. 3 has an advantage that it can be distributed and supported in a well-balanced manner and can stably travel.

  On the other hand, the handle 7 is disposed so as to extend obliquely forward from the vicinity of the swing axis B disposed below the seat 5, so that an open space is provided around the upper body of the seated operator A. Can be secured. As a result, the operator A can extend his hand to the vicinity of the ground of the drive wheels 3 while lying down in a sitting state. For example, when the electric mobility 1 is used for shopping in a supermarket or the like, the operator A himself / herself can pick up the commodity at the lower part of the display shelf.

  When the operator A is seated and extends both arms lightly forward, the operation portion 7c is disposed at that position, so both hands are placed side by side on the plate 9a of the operation portion 7c, and the plate 9a is moved by wrist movement. The vehicle can be steered simply by tilting the plate 9a forward and backward, changing the load applied to both hands, and tilting the plate 9a left and right.

  The plate 9a moves forward when the plate is inclined forward, moves backward when the plate is inclined backward, turns left when the plate is tilted left, and turns right when the plate is tilted to the right.

  Since both hands are arranged on the plate 9a, a moment in the opposite direction is applied with both hands around the axes of the first motor 11c and the second motor 11d constituting the operation portion 7c, as compared with the case of operating with only one hand. This makes it easy to balance the moments and finely adjust the speed and steering angle with both hands. Moreover, according to the operation part 7c with which the electric mobility 1 of this embodiment was equipped, it moves forward / backward and steers only by moving both hands placed on the plate 9a by changing the wrist angle or the elbow angle. be able to.

  Therefore, it is not necessary to hold the plate 9a or move the elbow back and forth, and even a pilot with a handicapped hand can be easily operated. In addition, according to this operation part 7c, instead of operating the plate 9a with both hands, if one hand is placed in the center of the plate 9a, the operation can be performed with only one hand.

  Further, in the electric mobility 1 according to the present embodiment, the left and right drive wheels 3 are separately controlled to take charge of both driving and steering, and the driven wheel 4 is configured by an omnidirectional wheel. Installation space is reduced. As a result, the driven wheel 4 having a large diameter can be adopted, and the road surface unevenness can be easily overcome.

  Moreover, since the axle of the driven wheel 4 is fixed to the vehicle body frame 2, the installation space in the width direction is particularly reduced. As a result, a sufficient footrest 6 can be secured even when the driven wheel 4 is brought close to the drive wheel 3, and the body frame 2 can be made compact.

In the present embodiment, the driving wheel 3 and the driven wheel 4 are arranged at intervals in the traveling direction. However, all the wheels may be driving wheels, or only one wheel may be a driving wheel. Good.
In the present embodiment, the angle of the handle is detected by the angle sensor 10, but the angle sensor 10 is not limited to the sensor that measures the angle, and the handle has a specific angle. A sensor for detecting this by magnetism or light is also included.

  In the present embodiment, the support mechanism 11 generates the reaction force of the force applied to the plate 9a by the first motor 11c and the second motor 11d. Instead, the reaction force is generated by a spring. You may decide to do it.

[Second Embodiment]

A rotating mechanism including a swing shaft 12, a lock mechanism, and an interlocking mechanism enables the seat 5 to rotate in the horizontal direction.

  When the left handle portion 7a and the operation portion 7c are connected (the state shown in FIG. 6), the interlocking mechanism is configured so that the seat 5 that does not rotate with respect to the vehicle body frame 2 has a swing angle of the left handle portion 7a. As the size increases, the state shown in FIG. 12 is assumed. Further, the interlocking mechanism is brought into the state shown in FIG. 13 as the swing angle of the left handle portion 7a further increases. The left handle portion 7a in the state shown in FIG. 12 corresponds to FIG. 8, and the left handle portion 7a in the state shown in FIG. 13 corresponds to FIG.

  As shown in FIGS. 12 and 13, the rotation mechanism of the second embodiment is configured so that the operator moves in the direction opened by the swinging of the left handle portion 7 a in a state where the left handle portion 7 a is separated from the operation portion 7 c. The seat 5 is rotated about the swing shaft 12 in conjunction with the swing of the left handle portion 7a so that A is directed.

The operation of the electric mobility 1 according to this embodiment configured as described above will be described below.
In the electric mobility 1 of the present embodiment, the rotation mechanism is fixed so that the seat 5 does not rotate when the left handle portion 7a is attached to the operation portion 7c, and the left handle portion 7a is separated from the operation portion 7c. In the state, the seat 5 is rotatable. By doing so, the seat 5 can be fixed and the seating state can be stabilized when the pilot A does not get on and off, and the passenger can easily get on and off when the pilot A gets on and off.

  The rotation mechanism includes an interlocking mechanism, and in a state where the left handle portion 7a is separated from the operation portion 7c, the left handle portion 7a is directed so that the operator A faces in a direction released by swinging the left handle portion 7a. The seat 5 is rotated in conjunction with the rocking motion. By doing in this way, the operator A simply moves the left handle 7a so that the operator A faces in the direction opened by the swing of the left handle 7a, and can easily get on and off. Can be.

Next, a third embodiment of the present invention will be described.
In the electric mobility 1 of the first embodiment, the right handle portion 7b and the right end of the operation portion 7c are connected at the position D so that they cannot be separated. On the other hand, in the electric mobility 1 of the third embodiment, the right handle portion 7b and the right end of the operation portion 7c are connected to each other at a position D so as to be separable.

  The mechanism for detachably connecting the right handle portion 7b and the right end of the operation portion 7c is the same as that described in the first embodiment. The swing mechanism of the right handle portion 7b of the third embodiment is the same as the swing mechanism of the left handle portion 7a described in the first embodiment.

  In the electric mobility 1 of the third embodiment, the right handle portion 7b and the right end of the operation portion 7c are connected to each other at a position D so as to be separable, and the left handle portion 7a and the left end of the operation portion 7c can be separated. It is connected at the position. In this way, the pilot A can get on and off from either the right side or the left side from a preferred direction.

  In addition, if the position C and the position D can be separated at the same time, there is a risk that the operation unit 7c may fall. Therefore, in this embodiment, in a state where the right handle portion 7b and the right end of the operation portion 7c are separated, the left handle portion 7a and the left end of the operation portion 7c are fixed so as not to be separated. Further, in a state where the left handle portion 7a and the left end of the operation portion 7c are separated, the right handle portion 7b and the right end of the operation portion 7c are fixed so as not to be separated.

[Other Embodiments]
In the first embodiment, the right handle portion 7b and the operation portion 7c are connected as an integrated part, but other modes may be used. For example, as shown in FIG. 14, the operation portion (front side member) 7 c is connected to the right handle portion (vehicle body side member) 7 b and the swing shaft (swing member) 13 so as to be swingable in the horizontal direction. It may be. Further, for example, the operation portion (front side member) 7c may be connected to the right handle portion (vehicle body side member) 7b and a swing shaft (swing member) (not shown) so as to be swingable in the vertical direction. .

  In the embodiment described above, armrests having such a length that does not hinder the swing of the handle 7 may be provided at the left and right ends of the seat 5. The length that does not cause an obstacle due to the swinging of the handle 7 is, for example, the width in the full length direction that is the same as the seat surface. By doing in this way, the effect that the arm can be put on an armrest at the time of boarding can be produced, without getting in the way of getting on and off.
