Description

Technical Field

[0001] The utility model relates to the field of transportation tools, in particular to a frame assembly structure of an electric three-wheeled truck. Background Art

[0002] Existing vehicle head frames are constructed of rectangular tubes and corresponding reinforcements. These components lack aesthetic appeal and are insufficiently strong, posing a risk of breakage. Furthermore, the controller mounting plate is placed horizontally, requiring the vehicle compartment to be opened for repair, making it difficult to maintain. Furthermore, electronic control devices, such as the controller, are currently built directly into the vehicle frame. These electronic devices are subject to constant vibrations caused by the vehicle's movements, making them susceptible to damage over time.

[0003] Currently, a utility model patented with the publication number CN205819411U discloses a large hydroelectric electric tricycle frame using a large seat bucket and a stamped windshield. The frame features not only novel and fashionable styles and a wide variety of models, but also a rational structure and durability. The technical solution of this utility model is characterized by: a stamped windshield is provided at the head of the front frame; a left curved beam and a right curved beam are connected to the front elevation of the pedal front crossbeam in an "N"-shaped symmetrical support pattern on both sides of the upper portion of the diagonal beam, greatly enhancing the diagonal beam's torque resistance; a large seat bucket is fixedly mounted in front of the frame's right-angled step; a battery frame is provided at the rear of the frame's right-angled step, with both sides of the battery frame connected to the left auxiliary beam and the inner elevation of the auxiliary beam's front end; a central main beam is in the shape of a sloped step; the rear horizontal plane of the central main beam supporting the battery frame is lower than the front horizontal plane, ensuring sufficient height from the rear upper plane of the central main beam to the upper plane of the rear frame to accommodate a lead-acid battery.

[0004] From the above disclosed technical content, it can be seen that as an existing technology, the utility model with the announcement number CN205819411U solves the problem of lead-acid battery installation through a double-layer frame, but does not provide a solution to the problem of no fixation of the controller and low maintenance convenience. At the same time, it does not provide an effective solution to the problem that the front beam is not beautiful enough and the strength is insufficient. Utility Model Content

[0005] In response to the problems existing in the above-mentioned prior art, the utility model provides an electric three-wheeled truck frame assembly structure, which can effectively improve the aesthetics and overall strength of the head frame, and can effectively solve the problems of the controller having no fixed installation position and low maintenance convenience.

[0006] In order to achieve the above-mentioned purpose, the utility model provides an electric three-wheeled truck frame assembly structure, including a shelf assembly, a rear vertical connecting beam, a chassis assembly, a front vertical connecting beam, an electrical installation plate, a head frame, a front oblique beam inner plate, a front oblique beam outer plate, a side reinforcement plate, a head tube, a front oblique beam reinforcement plate and a front oblique beam reinforcement tube. The shelf assembly is connected to the chassis assembly through the rear vertical connecting beam and the front vertical connecting beam to form a frame body. The electrical installation plate is fixedly installed between the two rear vertical connecting beams of the frame body. The head frame is fixedly installed on the upper front surface of the frame body. The front oblique beam reinforcement plate and the front oblique beam reinforcement tube are fixedly installed on the front of the frame body. The upper ends of the front oblique beam reinforcement plate and the front oblique beam reinforcement tube are fixedly connected to the head frame.

[0007] In addition, the electric three-wheeled truck frame assembly structure proposed in the above embodiment of the present invention may also have the following additional technical features:

[0008] As a further improvement scheme of the present invention, the head frame includes a front oblique beam inner plate and a front oblique beam outer plate, the front oblique beam inner plate and the front oblique beam outer plate are fitted together front to back, the top ends of the front oblique beam inner plate and the front oblique beam outer plate are fixedly installed with the head pipe, the two sides of the head pipe are respectively fixedly connected to the front oblique beam inner plate and the front oblique beam outer plate by side reinforcement plates, and the upper ends of the front oblique beam reinforcement plate and the front oblique beam reinforcement tube are fixedly connected to the front oblique beam inner plate of the head frame.

[0009] As a further improvement of the present invention, the side reinforcement plates and the headstock are provided with a direction lock installation hole and a direction lock locking hole.

[0010] As a further improvement of the present invention, heat dissipation holes are provided on the surface of the electrical installation board.

[0011] As a further improvement of the present invention, the headstock is tilted forward.
