Description

Technical Field

[0001] This utility model relates to the field of vehicle frame technology, specifically to a vehicle-mounted vehicle with a mid-mounted motor frame. Background Technology

[0002] With the rapid development of electric mobility scooter technology, its application in short-distance travel, scenic tours, logistics and distribution is becoming increasingly widespread. Traditional electric mobility scooters mostly adopt rear-wheel drive or hub motor solutions. The motor system is usually installed at the rear of the vehicle or directly integrated inside the wheel. This layout simplifies the transmission structure to a certain extent and meets basic driving requirements.

[0003] However, the existing technology of placing the motor at the rear of the vehicle has many drawbacks: First, the motor's rear location can easily cause the vehicle's center of gravity to shift rearward, resulting in uneven distribution of axle loads and affecting the vehicle's stability and handling. This is especially true when turning or on slippery surfaces, where it can easily lead to skidding or fishtailing. Second, because the motor is far from the vehicle's central control unit, the power supply and signal lines need to extend from the front or middle of the chassis to the rear. This results in long wiring paths, which not only increases wiring costs and assembly difficulty but also easily causes voltage drops and signal interference due to excessively long lines, affecting system efficiency and reliability. In addition, the rear-mounted motor structure occupies a large amount of space at the rear of the chassis, limiting the optimized layout of other functional modules. Summary of the Invention

[0004] The purpose of this utility model is to provide a vehicle with a mid-mounted electric motor frame to solve problems such as uneven center of gravity distribution, complex wiring, and structural occupation.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A chauffeur vehicle with a mid-mounted motor frame is provided, including a frame, a U-shaped base rotatably mounted at the bottom of the frame, a motor mount at the bottom of the U-shaped base, a rear swingarm mounted on the left side of the motor mount, a motor housed inside the motor mount, a rear wheel rotatably mounted on the rear swingarm, a drive belt connecting the motor and the rear wheel, a shock absorber between the frame and the rear swingarm, a seat compartment movably mounted on the top of the frame, and a pedal bracket protruding from the right side of the motor mount, with a sunburst groove at the end of the pedal bracket.

[0007] As a preferred solution for a vehicle with a mid-mounted electric motor frame, a rotating shaft is provided inside the U-shaped seat, the rotating shaft is rotatably connected to the frame, a square main beam tube is movably provided on the right side of the frame, a sealing cap is provided at the end of the square main beam tube, and a controller is provided inside the square main beam tube.

[0008] As a preferred solution for a vehicle with a mid-mounted electric motor frame, the bottom of the square main beam tube is provided with an irregularly shaped round tube, and the end of the irregularly shaped round tube is provided with a sunflower groove.

[0009] As a preferred embodiment of a mid-mounted electric motor frame vehicle, a front fork is provided at the top of the square main beam tube, a handlebar is provided at the top of the front fork, and a front wheel is provided at the bottom of the front fork.

[0010] The beneficial effects of this utility model are:

[0023] like Figure 1 and Figure 2As shown, this utility model provides a technical solution: a mid-mounted motor frame vehicle, including a frame 1, a U-shaped seat 2 rotatably mounted at the bottom of the frame 1, a rotating shaft 21 installed inside the U-shaped seat 2, the rotating shaft 21 being rotatably connected to the frame 1, facilitating replacement of the rotating shaft 21 after wear and reducing usage costs, a motor seat 3 installed at the bottom of the U-shaped seat 2, a rear swingarm 4 installed on the left side of the motor seat 3, a motor 5 installed inside the motor seat 3, a rear wheel 6 rotatably mounted on the rear swingarm 4, and a drive cable installed between the motor 5 and the rear wheel 6. A shock absorber 8 is installed between the bottom left side of the frame 1 and the top right side of the rear swingarm 4. A seat 9 is movably installed on the top of the frame 1, and a battery is installed in the seat 9. A pedal bracket 10 is protruding from the bottom right side of the motor mount 3. The end of the pedal bracket 10 has a sunflower groove. By welding the rear swingarm 4 and the motor mount 3 into one piece, and setting a U-shaped seat 2 on the motor mount 3, a hinged linkage suspension structure is formed with the shock absorber 8, which realizes the stable bearing of the motor 5 and the effective shock absorption of the rear wheel 6, improving riding comfort and driving stability.

[0024] like Figure 1 As shown, a square main beam tube 11 is movably mounted on the right side of the frame 1. A sealing cap 12 is installed at the end of the square main beam tube 11. A controller is installed inside the square main beam tube 11. A special-shaped round tube 13 is installed at the bottom of the square main beam tube 11. A sunflower groove is opened at the end of the special-shaped round tube 13. A front fork is installed on the top of the square main beam tube 11. A handlebar is installed on the top of the front fork. A front wheel is installed at the bottom of the front fork. By placing the motor 5 in the middle and integrating the battery, the wiring harness of the motor 5, and the controller into the main beam structure of the square main beam 11, not only can the wiring be effectively reduced and the operating cost lowered, but the concealed wiring design of the sealing cap 12 also facilitates subsequent maintenance. This achieves a reasonable distribution of the vehicle's center of gravity, stable handling, and completely concealed wiring, resulting in a simple and beautiful appearance. At the same time, the front and rear welded pedal brackets 10 and the special-shaped round tube 13 can be used to install pedals according to actual conditions, adapting to users of different heights, improving pedal comfort and ergonomic fit, especially meeting the riding needs of people taller than 1.7 meters and shorter.

[0025] Working principle: Before use, the battery, controller and motor 5 wiring are stored in the square main beam tube 11 and sealed with the sealing cover 12 for easy replacement or maintenance. When folded, the pedal bracket 10 contacts the ground to prevent the motor 5 from hitting the ground and being damaged. When in use, when encountering uneven terrain, the U-shaped seat 2 and shock absorber 8 move synchronously to reduce the vibration caused by uneven ground. At the same time, the centrally located motor 5 and the rear wheel 6 on the rear horizontal fork 4 form a stable overall structure to prevent the drive belt 7 between the motor 5 and the rear wheel 6 from loosening. The pedal can also be disassembled in real time according to different users and then installed in the sunflower groove of the pedal bracket 10 or the sunflower groove of the irregular round tube 13.

[0026] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed.
