Description

Technical Field

[0001] The present invention relates to the technical field of electric tractors for outdoor activities, and in particular to a tractor / trolley for outdoor activities (camping, picnics, hiking, crossing, entertainment and leisure, shopping, outdoor rescue, outdoor sports, events, etc.). Background Art

[0002] Outdoor activity trailers / trolleys, also known as camp trailers, camping trailers, camping trailers, etc., are usually used to transport outdoor equipment (such as energy storage power supplies, outdoor refrigerators, tents, catering equipment, food, communication equipment and other materials) from indoor or vehicle to the activity destination during outdoor activities. Its body adopts a folding structure, which can be easily unfolded, stored and transported without taking up too much storage space. However, since it is not equipped with power, it needs to be dragged by manpower to move it to achieve the purpose of transportation. The outdoor road conditions are complex and changeable (ramps, grass, sand, mud, gravel roads, etc.), and there are items placed in the car to move forward. It is very laborious and time-consuming to drag by manpower. When driving is difficult (such as uphill, sandy, etc.), it requires multiple people to push it. When going downhill, because the speed can only be controlled by human dragging, it is easy to lose control and cause danger.

[0003] Therefore, it is urgent to design an electric tractor for outdoor activities to overcome the deficiencies of one or more of the above-mentioned prior arts. Utility Model Content

[0017] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0018] like Figure 1-Figure 5As shown, the utility model provides an electric tractor for outdoor activities, comprising: a frame 10, two electric wheels 11 are provided at the bottom of one end of the frame 10, two direction wheels 12 are provided on the side of the frame 10 away from the electric wheels 11, a controller 13 is provided at one end of the frame 10, the controller 13 is electrically connected to the electric wheels 11, a power supply 14 is provided at the end of the frame 10 away from the controller 13, the power supply 14 is electrically connected to the controller 13, a handle 15 for controlling the direction of the vehicle is rotatably connected to the middle of the end of the frame 10 where the direction wheels 12 are provided, a control button 19 for controlling the start, speed and dragging / pushing of the electric wheel 11 is provided at the end of the handle 15 away from the frame 10, specifically, the electric wheel 11 adopts a wheel hub motor for driving the wheel to rotate, and the wheel hub motor is connected to the controller 13 through an electric wire, The controller 13 is connected to the power supply 14, and sends a specific control signal through the control button 19 on the handle 15. The controller 13 receives the signal through the wire and analyzes and identifies it, and sends a control instruction according to the identification result, and controls the rotation, speed and forward and reverse rotation of the electric wheel 11 through the wire. The specific control principle / process can refer to the working principle of the instruction sending end, controller and execution end in the existing electric bicycle and electric wheelchair, so that the outdoor activity towing / pushing cart is transformed from the original human dragging mode to the electric drive mode or can provide assistance in some special environments, which is convenient for users to use. Among them, the handle 15 is linked with the two direction wheels 12, that is, when the handle 15 rotates to the left, the two direction wheels 12 can be driven by the handle 15 and turn to the left synchronously. The connection structure of the handle 15 and the direction wheel 12 can refer to the connection structure of the existing hand forklift, which will not be described here.

[0019] Furthermore, in the present embodiment, the frame 10 can be detachably connected to a carriage 18 with a top opening. Specifically, the detachable carriage 18 is used to place articles. When in use, the carriage 18 can be removed according to the size of the articles. The carriage is supported by a flexible material, such as cloth, for easy folding.

[0020] Furthermore, in the present embodiment, two first baffle bars 16 are rotatably connected to the middle part of the frame 10, and the two first baffle bars 16 rotate in opposite directions. Specifically, the first baffle bars 16 are used to prevent items placed on the frame 10 from falling out of the frame 10. The two first baffle bars are rotatably arranged in opposite directions, that is, one rotates toward one end of the frame 10, and the other rotates toward the other end of the frame 10, so that the two first baffle bars 16 are in a "V" shape as a whole, thereby blocking the items in the frame 10 and preventing the items from falling.

[0021] Furthermore, in the present embodiment, the first barrier rod 16 is in a "U" shape, and the open end of the first barrier rod 16 is rotatably connected to the frame 10. In order to realize that one first barrier rod can block the pillars on both sides of the frame 10, the two first barrier rods 16 are arranged in a "U" shape, so that one first horizontal bar can block both sides of the pillar. At the same time, because the two first barrier rods 16 are respectively rotated and tilted toward the two ends, the first barrier rod 16 can realize the blocking function at the front and rear ends in addition to the blocking function at the two sides.

[0022] Further, the bottom of both ends of the frame 10 are respectively connected to second gears 17, and the two second gears 17 are rotatably connected together away from one end connected to the frame 10, and the two second gears 17 are intersected with the two first gears 16 one by one, and the first gears 16 are connected with the second gears 17 at the intersection. Specifically, because the blocking range of the first gear 16 is limited, in order to expand the blocking range, the second gears 17 are rotatably connected to the two ends of the frame 10, and the two second gears are respectively intersected with the two first gears, and the second gears are connected to the first gears. The first gear lever and the second gear lever are connected at the intersection, and the connection at the intersection is used to fix the first gear lever and the second gear lever to each other. At the same time, in order to prevent the second gear lever from loosening, the two second gear levers are connected together by rotating the ends away from the frame 10 through a connecting piece, thereby preventing the two second gear levers from loosening. At the same time, the fixation is achieved by the cooperation of the first gear lever and the second gear lever, and there is no need to set up other limiting structures. At the same time, after loosening one end of the first gear lever connected to the frame, the first gear lever and the second gear lever can be folded up. It should be noted that the frame can also be folded along the middle so that the entire frame can be folded up.

[0023] In summary, the utility model converts a traditional outdoor activity trolley into an outdoor activity electric trolley by providing an electric wheel 11 and a controller 13, and has a simple structure and low installation cost, which greatly improves the convenience and practicality of the outdoor activity trolley when used outdoors.

[0024] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
