Detailed ways

Transport device 2 as shown in Figures 3-6, comprises chassis 4, is adapted to the upright golf bag 6 (Figure 3) that is used for placing golf equipment at the front end, and the opening shape of described ball bag is adapted to golf club . The shape design of the chassis 4 is relatively flexible, and may include a non-rotatable front wheel 8 and a platform 10, and a rotatable steering rear wheel 34 connected at the rear of the vehicle, as well as an upper transverse handlebar 16 and a handle 18 connected to the steering component 14 . Steering rear wheels 34 are respectively connected on the protruding positions on both sides of the end of platform 10, and steering rear wheels 34 are rotatably fixed at the connection with the platform. The size of steering rear wheels 34 is smaller than the front wheels, and together with the larger front The wheels 8 form a transport device 2 with a relatively low chassis. Simultaneously, the steering rear wheel is regulated by two transverse transmission rods 22, and is connected and driven by the transmission rods consistent with the driving direction of the transport device, and finally regulated by the steering component 14. Since the present invention employs two separate steering rear wheels 34 here, the transport device can be provided by means of two laterally extending steering rods between the bottom end of the handlebar 16 and the swivel arm of each rear wheel 34. The protruding arm is used to adjust the rear wheel 34 from the steering part 14 at the front wheel position, so as to control the forward direction of the transport device conveniently.

Referring to FIG. 3 , it is a structural schematic diagram of the improved handlebar and steering system of the transportation device of the present invention. The steering system includes a steering component 14, a handlebar 16, a handle 18 (the specific handle is not shown in this figure), and a plurality of joysticks 22 connected to the lower part of the chassis for steering transmission. There is a telescopic component 15 on the front of the steering component, which is used to adjust the upper half of the steering component 14 to telescopically move and fix therein. The fixing method can be fixed by ordinary bolts and holes or by automatically engaging layered fixing elements. An upper holding part 17 and a lower holding part 19 are also provided on the turning part 14 for holding and fixing the golf bag 6 . The contact surfaces between the upper holding part 17 and the lower holding part 19 and the golf bag 6 are designed to be arc-shaped so as to be close to the golf bag. The ends of the curved contact surfaces of the upper holding member 17 and the lower holding member 19 are provided with holes for passing through the ropes, and nylon or other common ropes are used to pass through the holes and bypass the golf bag 6 Or put the golf bag 6 on the elastic rope near the holding part, the golf bag 6 can be fixed on the steering part 14, which is easy and not easy to drop.

The steering member 14 is pivotably connected to the chassis 4 at the bottom so that the steering member 14 can be adjusted as a unit between horizontal and vertical positions at its bottom end by pivoting backwards and downwards. (See Fig. 4 and Fig. 5), also can be adjusted as the position that forms 45 ° of angles as shown in Fig. 3. Referring to FIG. 6 , the steering component 14 can be fully rotated to the level and placed flat on the corresponding position of the platform 10 . At this time, the handlebar 16 is operated to be placed on the outside of the rear wheel bogie 12 , that is, it is completely behind the transport device 2 .

Shown clearly by Fig. 3 and Fig. 4, the tail end both sides of platform 10 is provided with the steering rear wheel 34 that can pivot steering, and described steering rear wheel is connected with the vertical guide rod (not shown in the figure) of platform contact position. out) so that it can realize the steering action around the direction of the value axis.

At the same time, in another preferred solution of the present invention, the rotatable rear wheel bogie 12 connected at the rear of the vehicle, the rear wheel bogie 12 provides a relatively large rear wheel 13, and the rear wheel 13 forms a width equal to almost The rear lateral support rollers of the rear platform form a relatively low transport device 2 with a relatively low chassis together with the wider front wheels 8 , and the transport device will not easily tip over due to this special low chassis design.

The side-by-side rear wheel bogies 12 are rotatably connected to a rearward connection member 20 on the platform 10, and a joystick 22 is pivotally connected to the rear wheel bogies 12, the connection point is located at the lateral separation The area between the rear wheel bogie 12 and the rear end of the platform 10 .

The described rear wheel bogie 12 is installed, and can be disassembled by turning to the rear wheel 34 first, and then connected with the round hole at the end of the platform 10 through the connecting part of the rear wheel bogie, and fixed rotatably, while the rear wheel The bayonet at the front end of the bogie is matched with the limit groove at the appropriate position of the chassis to prevent the rear wheel bogie from turning too much.

At the bottom of the transport device 2 , the front end of the front end joystick 22 interacts with the bottom end of the steering part 14 , and gears can be arranged between the joystick 22 and the steering part 14 for mutual transmission.

It is clearly shown in the transport device 2 that each front wheel 8 is directly driven in connection with an electric gear motor 24 powered by two rechargeable batteries 26 and associated with a control unit not shown in the figure , the control unit is integrally formed in the central housing 30 at the rear end of a steering component 14, and is controlled and connected by a governor not shown in the figure.

Normally, the transporter 2 is not required to have an actual parking brake system, since the geared electric motor 24 is usually self-braking. The transport device 2 therefore has a parking brake anyway, such as a self-braking gear, so that the transport device can be safely parked on sloped terrain.

The transport device 2 can also have an actual motor brake. In the control of the electric motor, a module called "ramp function" is included to ensure a stable and soft starting mode, controlled by a spring balance valve, that is, when the control valve is released, to achieve automatic return to the neutral. The transport device 2 can also provide a tow hook, so that the transport device 2 can also be used as a working vehicle to maintain golf courses, gardens and parks.

When the transport device 2 needs to be towed or pushed, it is preferably implemented by inserting a suitable coupling between the front wheel 8 and the transmission shaft of the geared motor. The coupling can control the interlocking or loosening of the axles between the drive wheels and the motor. Specifically, when output power is required, the controller selects the engaging mode; when only dragging is required, the controller selects the loosening mode. Since the technology of the shaft coupling is very mature and not the focus of the present invention, it will not be described in detail here.

The transport device 2 is preferably made of lightweight materials to the greatest extent, so that each of its components will be of as light a material as possible. For example, the platform 10 is in the form of a supporting frame made of aluminum and the upper load-bearing surface of the shell structure made of reinforced plastic such as glass fiber reinforced thermosetting plastic.

Additionally, the use of the rear wheel bogie 12 in hilly terrain may result in inconvenience due to the greater motor output required for the larger drum shaped rear wheel 13 . Therefore, instead, two separate rear wheels are also used to control the direction of the transport device.

Finally, it should be mentioned that this is the scope of the present invention, and the transportation device 2, 32 disclosed by it can also be applied in other fields, such as people's transportation in hospitals, airports, shopping malls, warehouses, etc. Way.
