Description

Technical Field

[0001] This application relates to the field of scooter technology, and more particularly to a cargo scooter. Background Technology

[0002] Scooters have gradually evolved from recreational tools to commuting tools, with increasing demands for multi-functionality, such as cargo carrying. However, due to the narrow frame of scooters, cargo space is limited, and the length is basically only enough to accommodate two feet. If cargo is placed on the scooter, the space for the feet becomes even more limited. Increasing the length of the frame would increase the difficulty of driving, but the cargo carrying capacity is limited within the limited length.

[0003] Chinese patent application CN107672720B, entitled "Skateboard," discloses a scooter comprising: a frame assembly including a main frame with a passenger space and a sub-frame, wherein the sub-frame is movably connected to the main frame and can unfold away from the main frame at its connection point, forming a cargo space when unfolded; and a wheel assembly connected to the frame assembly. While this design increases cargo space, it results in a complex steering structure, increased frame length, and increased difficulty of driving. It also requires a wider road surface for steering, making it unsuitable for driving in narrow spaces such as alleyways.

[0004] Chinese patent application CN217554080U, entitled "An Intelligent Skateboard Carrying Bicycle," discloses an intelligent skateboard carrying bicycle. Its key technical features include pedals, a front wheel, and a rear wheel. Through holes provide a rotation area for the front fork, a front fork bracket provides a rotation area for the front wheel, a second bracket provides a rotation area for the rear wheel, and a second bracket provides a fixed location for the cargo frame. The cargo frame, positioned above the rear wheel, facilitates the operator's placement and retrieval of goods. The front wheel, rear wheel, and pedals, supported by the first bracket, second bracket, connecting block, and front fork bracket, form the skateboard. The pedals provide a standing area for the operator, who can stand on one foot while the other foot intermittently contacts the ground, driving the front and rear wheels to rotate and thus propelling the cargo frame to move and transport goods. However, the cargo area is located at the rear, making it prone to falling and difficult to observe the cargo, making it unsuitable for placing valuable goods. Utility Model Content

[0005] This application provides a cargo-carrying scooter to at least solve the cargo-carrying capacity technical problems existing in the prior art.

[0006] According to this application, a cargo scooter is provided, including a frame, a front wheel, a rear wheel, a pole, and a handlebar. The front wheel is rotatably fixed to the pole, the rear wheel is rotatably fixed to the frame, the pole is rotatably fixed to the front end of the frame, and the handlebar is fixed to the pole. A first mounting part is provided on the left side of the rear end of the frame, and the first mounting part has a left bracket that extends from the frame to the left. A second mounting part is provided on the right side of the rear end of the frame, and the second mounting part has a right bracket that extends from the frame to the right.

[0007] Compared with the prior art, the cargo scooter of this application has the following advantages:

[0008] By adding left and right supports, the width of the rear of the chassis can be increased, allowing two people to stand side by side. This provides more cargo space at the front of the chassis, enabling the loading of more goods while keeping them within sight. This is particularly beneficial for countries or regions with higher crime rates, enhancing cargo safety. With the center of gravity of the cargo located between the front and rear wheels, it offers better maneuverability compared to racks placed around the rear wheels, thus increasing the maximum load capacity.

[0009] In one embodiment, the pole includes a vertical bar and a horizontal bar. The horizontal bar is located at the top of the vertical bar, and the handlebars are located at the rear end of the horizontal bar. The handlebars extend to the left and right sides for a certain distance and then extend to the rear. In this way, the handlebars are positioned relatively far back, and the rider can operate the handlebars to drive even if they are standing near the rear wheel, without having to lean forward, making the driving posture more effortless.

[0010] In one embodiment, a headlight is located at the front end of the crossbar, and a display screen is located at the upper end of the crossbar. The front end of the display screen is tilted upwards, and the front end of the headlight is tilted downwards. By installing a housing on the outside of the crossbar, the display screen and headlight can be enclosed internally to form a unified structure, resulting in a more aesthetically pleasing overall design. The display screen can show information such as vehicle speed, making driving more convenient.

[0011] In one embodiment, a left pedal is provided above the left support and a right pedal is provided above the right support. The left and right pedals can be designed into different shapes as needed. The left and right supports are designed into a triangular shape, that is, smaller at the bottom and gradually increasing from bottom to top, so that the vehicle is less likely to scrape the ground when it turns and tilts.

[0012] In one embodiment, anti-slip mats are provided above the left and right pedals, making driving safer and preventing the pedals from slipping off even on bumpy roads.

[0013] In one embodiment, the frame includes an arc-shaped tube, a vertical tube, a tail plate, a first tube layer, and a second tube layer. The first tube layer is located above the second tube layer, and the first tube layer and the second tube layer are connected by multiple vertical tubes. The front ends of the first tube layer and the second tube layer are provided with arc-shaped tubes, and the rear ends of the first tube layer and the second tube layer are provided with tail plates. The rotation axle of the rear wheel is fixed to the tail plate. This design results in a stronger frame and allows for full utilization of the internal space, such as for placing batteries and electronic control structures.

[0014] In one embodiment, a front shelf is provided above the front end of the first tube layer. The lower front end of the front shelf has an arc-shaped groove that matches the arc-shaped tube, allowing the tube to be inserted into the groove. A rear shelf is provided above the rear wheels and fixed to the tailgate. This allows the front shelf to be quickly positioned in the center and then fixed to the frame with screws. The rear shelf can serve as an auxiliary shelf for temporary use or for storing appropriately sized items.

[0015] In one embodiment, a seat post is provided at the rear of the frame. The seat post is located in front of the rear wheel and its upper and lower ends are connected to the first tube layer and the second tube layer. A seat can be installed on the seat post, which makes it easier to ride the scooter and allows for a longer ride distance.

[0016] In one embodiment, a transition tube is provided inside the seat tube, and a seat is installed above the transition tube. The transition tube has a vertical groove and a first oblique cut tube and a second oblique cut tube are provided inside. The first oblique cut tube is located above the second oblique cut tube. The first oblique cut tube and the second oblique cut tube are connected by a first screw. The first screw extends upward from the second tube layer to connect with the second oblique cut tube. Thus, by rotating the first screw, the distance between the first oblique cut tube and the second oblique cut tube can be adjusted. Finally, the first oblique cut tube and the second oblique cut tube are aligned with the slope.

[0017] In one embodiment, the width of the rear wheel is greater than the width of the front wheel, and the diameter of the front wheel is greater than the diameter of the rear wheel. With the rear wheel width exceeding a certain range, the scooter can remain upright and prevent tipping. Furthermore, a wider rear wheel provides more stable driving friction. A larger diameter front wheel offers better maneuverability and ensures better steering performance, while a narrower front wheel provides less resistance.
