Description

Technical Field

[0001] The utility model belongs to the technical field of electric tricycles, and particularly relates to a front body structure of a reverse tricycle and an electric reverse tricycle vending vehicle formed therefrom. Background Art

[0002] A reverse tricycle is a special form of tricycle with two parallel wheels at the front and one wheel at the rear. When riding, the rider faces the direction of the two front wheels, while the rear wheel is located behind the rider.

[0003] The advantage of this inverted tricycle is that the rider faces the two front wheels when riding, and the cargo area is above the two front wheels. In this way, the rider can see the situation of the cargo area in real time during riding. Therefore, this inverted tricycle is particularly suitable for use as a catering vending vehicle.

[0004] With the development of electric bicycle technology, traditional pedal-type reverse tricycles are gradually developing towards electric reverse tricycles. Figure 1 Existing inverted tricycles usually use a relatively long integral frame main beam a, and the two front wheels b are installed on the front end of the integral frame main beam a through the front wheel frame c. The bottom of the front wheel frame c is installed on the front end of the integral frame main beam a through a vertical rotating shaft d. The cargo bed e and the front wheel frame c are fixedly installed (the cargo bed is set on the front wheel frame, or the cargo bed and the front wheel frame are designed to be an integrated structure). The handle f is connected to the cargo bed e or the front wheel frame, and the handle is used to control the cargo bed and the front wheel support to rotate together, thereby realizing the steering of the vehicle body. In other words, this traditional inverted tricycle structure requires a relatively long integral frame main beam as the connecting body. Such large-span steel beams are usually expensive, occupy a large area, are not convenient for transportation, and have high bearing strength requirements.

[0005] Currently available electric bicycles (two-wheeled) also have a structure including a frame, but the frame is shorter. If the frame of the existing two-wheeled electric bicycle can be applied to a reverse tricycle, production costs can be greatly saved, and a reverse tricycle can also be converted from an old / idle two-wheeled electric bicycle. Utility Model Content

[0006] The utility model is mainly intended to overcome the deficiencies of the prior art and provides a front body structure of a reverse tricycle and an electric reverse tricycle vending vehicle formed therefrom.

[0007] The utility model is realized through the following technical solutions:

[0031] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0032] A reverse tricycle, see attached Figure 2 , including the front body part and the rear body part.

[0033] The front vehicle body portion includes a front frame 1, two front wheel assemblies 2, a handlebar assembly 3 and a vertical rotation mounting member 4. The two front wheel assemblies 2 are mounted at the bottom of the front frame 1, the handlebar assembly 3 is mounted above the rear of the front frame 1, and the vertical rotation mounting member 4 is vertically mounted at the rear of the front frame 1.

[0034] Furthermore, a preferred specific structure of the front frame 1 includes a chassis and a vertical frame. The chassis includes two parallel longitudinal beams 11 and a plurality of cross beams 12 connected between the two longitudinal beams. The vertical frame is fixedly welded to the rear end of the chassis, and the vertical rotatable mounting member 4 is vertically mounted on the vertical frame. Specifically, the vertical frame includes a U-shaped tube 13 and a supporting cross beam 14 connected to the U-shaped tube 13. In this embodiment, there are preferably two supporting cross beams 14. The vertical rotatable mounting member 4 is vertically fixedly mounted on these two supporting cross beams 14. Furthermore, the vertical rotatable mounting member 4 is arranged along the vertical bisector of the vertical frame. Furthermore, the rear end of the U-shaped tube 13 further includes a curved tube section 131, the outer end of which is fixedly welded to the chassis, thereby ensuring the connection strength between the vertical frame and the chassis. Furthermore, a front bumper 15 is provided at the front end of the chassis of the front frame 1, and a towing handle 16 is provided on the front bumper.

[0035] The rear body portion includes a rear frame 5 and a rear wheel assembly 6. The rear wheel assembly 6 is mounted on the rear frame 5. The front portion of the rear frame 5 is rotatably mounted on the vertical rotatable mounting member 4 of the front body portion. The steering of the tricycle is controlled by operating the handlebar assembly 3. A battery box 7 and a rear seat 8 are also provided on the rear frame 5. The rear wheel assembly 6 uses a motor to drive the wheels, and the battery in the battery box 7 supplies power to it. Thus, the inverted tricycle of the present invention realizes an electric inverted tricycle. A cargo area is provided on the front body portion of the electric inverted tricycle, so that during electric driving, the driver can see the situation in the cargo area in real time. Therefore, this inverted tricycle is particularly suitable for use as an electric catering vending vehicle.

[0036] Furthermore, a first connecting member 91 is welded to the top of the front vertical tube 9 of the rear frame 5, and the first connecting member 91 is rotatably mounted on the top of the vertical rotating mounting member 4; a second connecting member 92 is welded to the front end of the bottom beam of the rear frame 5, and the second connecting member 92 is rotatably mounted on the bottom of the vertical rotating mounting member 4; thereby, the rear frame 5 is rotatably mounted on the vertical rotating mounting member 4 of the front body part, so that the front body part and the rear body part can rotate relative to each other around the vertical rotating mounting member 4.

[0037] For further information, see Appendix Figure 3 and attached Figure 4 Two steering range limiters 10 are provided on the vertical frame of the front vehicle body portion 1. These two steering range limiters 10 are symmetrically arranged on the left and right sides of the vertical rotation mounting member 4. Preferably, in this embodiment, the steering range limiter 10 has a specific structure as follows: it includes a roller 102 and a roller mounting frame 101. The roller 102 is mounted on the front end of the roller mounting frame 101, and the rear end of the roller mounting frame 101 is fixed to the vertical frame of the front vehicle body 1. When the vehicle body turns, if the steering range is too large, the roller 102 will block the front vertical pipe 9 of the rear frame 5. Alternatively, see the attached Figure 5 The steering range limiter 10 adopts a damping rod 103 , one end of the damping rod 103 is hinged to the vertical frame of the front frame 1 , and the other end of the damping rod 103 is hinged to the front vertical pipe 9 .

[0038] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0039] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.

[0040] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other technical personnel in this field without expending creative labor falls within the scope of protection of the present invention.
