Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention connects a front working machine such as a brush cleaner for floor cleaning or a mop machine to the front of a self-propelled small electric vehicle equipped with a steering wheel and a driver's seat to connect a self-propelled small electric vehicle. It is intended to be versatile.

[0002]

[Prior Art]

 Conventionally, there has been no attempt to make a self-propelled small electric vehicle versatile by connecting a front working machine such as a brush cleaner for floor cleaning or a mop machine to the front of the small electric vehicle.

[0003]

[Problems to be solved by the device]

 Therefore, it is conceivable to connect a front working machine to the front part of the small electric vehicle to make the self-propelled small electric vehicle more versatile. By installing a pair of left and right connecting brackets at the foremost end of the electric vehicle and connecting the pair of left and right connecting brackets to the pair of left and right connecting brackets at the rear end of the front working machine through a pair of left and right connecting links, front work When the machine is removed, the connecting metal fittings protrude from the front part of the small electric vehicle, which may cause contact with other objects during traveling, and may be easily damaged. Also, since the length of the connecting link that attaches the front working machine close to the front part of the small electric vehicle is short, the angle of the connecting link becomes large when the front working machine moves up and down due to the unevenness of the road surface. There is an inconvenience that the vertical work force acting on the connecting link becomes large and the front working machine cannot be pushed normally. The present invention is designed to connect a front working machine to the front part of a small electric vehicle to make the small electric vehicle more versatile, and avoids the danger of removing the front working machine, as well as the road surface. The purpose is to enable the front work implement to be pushed normally regardless of the irregularities on the front.

[0004]

Means for Solving the Problems A characteristic configuration of the present invention for achieving the above object is that a body frame of a small electric vehicle is formed in a U-shape in plan view, the width being narrower toward the front side of the vehicle body. In a side view, the front frame part is configured to be higher than the intermediate step frame part, and the vertical frame part that connects the front frame part and the step frame part of the body frame is , A pair of left and right connecting metal fittings for connecting the front working machine are fixedly connected, and the pair of left and right connecting metal fittings and the left and right connecting metal fittings at the rear end of the front working machine are connected via a pair of left and right connecting arms. It is in.

[0005]

[Action]

 Since the connecting metal fittings are provided on the vertical frame portion that connects the front frame portion and the step frame portion of the vehicle body frame, the connecting metal fittings may protrude to the front portion of the small electric vehicle when the front working machine is removed. The connector does not come into contact with other objects. Further, since the connecting fitting is located on the inner side of the machine body with respect to the outermost lateral portion of the vehicle body, there is no danger in the state where the front working machine is removed. Furthermore, since the connecting metal fitting is located behind the foremost end of the small electric vehicle, the connecting link that attaches the front working machine in close proximity to the front of the small electric vehicle becomes long, and the front and The angle of the connecting link when the working machine moves up and down can be reduced, and the vertical component force acting on the connecting link is reduced, so that the front working machine can be pushed normally.

[0006]

[Effect of the device]

 As a result of the above configuration, it is possible to increase the versatility of a self-propelled small electric vehicle by connecting a front working machine such as a brush cleaner for floor cleaning or a mop machine to the front of the small electric vehicle. Therefore, the danger of removing the front work implement and good towing work can be performed.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings with respect to a small electric vehicle manufactured for an elderly person to use instead of a wheelchair. As shown in FIG. 1, a single front wheel 2 for steering and a steering handle 3 for steering the front wheel 2 are attached to the front part of a body frame 1 made of a metal pipe frame. The rear part of the body frame 1 is provided with a pair of left and right rear wheels 4, 4, an electric motor 5 for driving the rear wheels, and a driver's seat 6 to form a three-wheel type small electric vehicle. Then, a resin front cover 7 that covers the upper side of the front wheel 2 is attached to the front side of the vehicle body frame 1, and the rear wheel 4 and the electric motor 5 are covered on the rear side of the vehicle body frame 1. A rear cover 8 made of resin is attached. The vehicle body frame 1 has a U-shape that is formed narrower toward the front side of the vehicle body in a plan view, and the frame portion 1a on the front side is higher than the step frame portion 1c in the middle section in a side view. Has been done. A pair of left and right connecting fittings 9 and 9 for connecting the front working machine are fixedly connected to the vertically oriented frame portion 1b connecting the front frame portion 1a and the step frame portion 1c. On the other hand, on the rear end of the frame 11 of the floor cleaning brush cleaner B equipped with the rotating brush 10 for cleaning the floor as a front working machine connected to the front part of the small electric vehicle A, a pair of left and right connecting fittings is provided. The pair of left and right connecting fittings 12, 12 on the working machine side and the pair of left and right connecting fittings 9, 9 on the small electric vehicle side form a pair of left and right connecting links 13, 13. Are connected through.

[Other Embodiments] The other end of the connecting link 13 pivotally connected to the connecting fitting 12 on the front working machine B side via a pin is used to engage with a fixing pin on the small electric vehicle A side. The slit 12a may be formed to form a hook-type engagement structure.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the invention is not limited to the configuration of the accompanying drawings by the entry.
