Abstract
Description
Technical Field
[0001] This utility model relates to the field of transportation technology, specifically to an electric tricycle frame that facilitates cable routing. Background Technology
[0002] As an important tool for short-distance transportation and cargo carrying, the design of the frame structure of electric tricycles directly affects the reliability, safety, and production efficiency of the entire vehicle. Currently, electric tricycle frames on the market mainly focus on mechanical strength and load-bearing capacity, while insufficient optimization of the internal electrical system layout. This leads to problems such as chaotic wiring layout, difficulties in inspection and maintenance, and even the risk of short circuits and fires caused by friction due to loosely fixed wires. Utility Model Content
[0003] This utility model provides an electric tricycle frame that facilitates cable routing. Through structural reinforcement and functional zoning, it solves the pain points of mechanical reliability and electrical system management, and is especially suitable for commercial electric tricycles that are used under high load and with high frequency.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an electric tricycle frame for easy cable routing, comprising: a chassis, the chassis being composed of a horizontally arranged central beam and bottom side beams parallel to both sides of the central beam, with the tail ends of each bottom side beam curving upwards; an upper side beam, the upper side beam being arranged parallel above the bottom side beams and fixedly connected to the tail ends of the corresponding bottom side beams via a middle section, the front ends of each upper side beam being fixedly connected to the middle section of the bottom side beams via vertical side longitudinal beams, and the side longitudinal beams having an equipment panel corresponding to the rear of the chassis; a battery tray, the battery tray being fixedly arranged at the rear of the chassis and corresponding to the front of the upper side beams; and a main cable clamp, the main cable clamp being disposed on the inner side of the upper side beams.
[0005] Preferably, a front crossbeam, a middle crossbeam, and a rear crossbeam are provided between the two upper beams, and the tail end of the middle beam is fixedly connected to the middle crossbeam through a middle longitudinal beam; it also includes an equipment tray, which is fixedly connected to the bottom of the middle crossbeam.
[0006] Preferably, it also includes a flat plate, which is hinged to the tail end of the upper beam, and a locking buckle is provided between the front end of the upper beam and the flat plate.
[0007] Preferably, it also includes a branch cable clamp disposed on one side of the rear crossbeam.
[0008] Preferably, it also includes a converter bracket, which is fixedly disposed on one side of the upper beam.
[0009] The beneficial effects of this utility model are as follows: The core design of this electric tricycle frame optimizes the management of the electrical system through structured wiring space and modular layout. Its layered frame structure forms a three-dimensional space, thereby dividing functional areas. Simultaneously, the space at the top of the frame is used as a "cable channel," allowing cables to run along a predetermined path, avoiding sag or contact with moving parts. The main cable clamps constrain and plan the electrical wiring, effectively preventing interference with the mechanical structure. Switches, displays, fuses, and other components are centrally mounted on the equipment panel, achieving a centralized layout, shortening wiring harness length, and reducing clutter. The battery tray, serving as the weight and main power source, is located at the rear of the vehicle near the drive wheels, balancing the center of gravity and shortening the distance to the high-voltage lines of the motor / controller, thus reducing energy loss. The front, middle, and rear crossbeams form a closed rectangular frame structure, significantly improving the frame's torsional rigidity and preventing frame deformation under heavy loads or bumps, making it particularly suitable for rough roads or heavy-duty transportation scenarios. The central longitudinal beam connects the middle beam and the central crossbeam, distributing chassis stress and preventing rear-end sagging due to concentrated battery or cargo weight. The equipment tray, fixed to the bottom of the central crossbeam, provides a dedicated mounting platform for electrical equipment such as controllers, relays, and DC-DC converters, preventing direct exposure to the external environment. Simultaneously, the central crossbeam acts as an "electrical hub," bringing the equipment tray close to the battery and main cable clamps, shortening the length of high-voltage wiring harnesses and reducing power loss and electromagnetic interference. The flat panel, acting as an "openable cover," allows for upward rotation, directly exposing the battery tray, equipment panel, or main cable clamps below. Therefore, electrical system maintenance and repair can be performed without disassembling the entire cargo box or chassis cover. Branch cable clamps manage branch lines, such as low-voltage harnesses for taillights, turn signals, and brake signal lines, preventing entanglement with high-voltage lines, reducing signal misinterpretation due to electromagnetic interference, and facilitating quick location of faulty lines without requiring a full-line inspection.

[0013] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0014] according to Figure 1 As shown, an electric tricycle frame for easy cable routing includes: a chassis, the chassis being composed of a horizontally arranged center beam 1 and bottom side beams 2 parallel to both sides of the center beam 1, with the tail ends of each bottom side beam 2 curving upwards; an upper side beam 3, the upper side beam 3 being arranged parallel above the bottom side beams 2 and fixedly connected to the tail ends of the corresponding bottom side beams 2 via a middle section, the front ends of each upper side beam 3 being fixedly connected to the middle section of the bottom side beams 2 via vertical side longitudinal beams 4, and the side longitudinal beams 4 having an equipment panel 16 corresponding to the rear of the chassis; a battery tray 5, the battery tray 5 being fixedly arranged at the rear of the chassis and corresponding to the front of the upper side beam 3; and a main cable clamp 6, the main cable clamp 6 being disposed inside the upper side beam 3.
[0015] The core design of this electric tricycle frame optimizes electrical system management through structured wiring space and modular layout. Its layered frame structure creates a three-dimensional space, thus dividing functional areas. Simultaneously, the space above the frame serves as a "cable tray," allowing cables to run along predetermined paths, preventing sags or contact with moving parts. The main cable clamps 6 constrain and plan the electrical wiring, effectively preventing interference with the mechanical structure. The equipment panel 16 centrally houses switches, displays, fuses, and other components, achieving a centralized layout, shortening wiring harness length, and reducing clutter. The battery tray 5, serving as both a weight and the main power source, is positioned at the rear of the vehicle near the drive wheels, balancing the center of gravity and shortening the distance to the high-voltage lines of the motor / controller, thus reducing energy loss.
[0016] A front crossbeam 7, a middle crossbeam 8, and a rear crossbeam 9 are provided between the two upper beams 3. The tail end of the middle beam 1 is fixedly connected to the middle crossbeam 8 through a middle longitudinal beam 15. The equipment tray 10 is also included, and the equipment tray 10 is fixedly connected to the bottom of the middle crossbeam 8.
[0017] The front crossbeam 7, middle crossbeam 8, and rear crossbeam 9 form a closed rectangular frame structure, significantly improving the torsional rigidity of the chassis and preventing chassis deformation under heavy loads or bumps, making it particularly suitable for rough roads or heavy-duty transportation scenarios. The middle longitudinal beam 15 connects the middle beam 1 and the middle crossbeam 8, distributing chassis stress and preventing rear-end sagging due to concentrated battery or cargo weight. The equipment tray 10 is fixed to the bottom of the middle crossbeam 8, providing a dedicated mounting platform for electrical equipment such as controllers, relays, and DC-DC converters, avoiding direct exposure to the external environment. At the same time, the middle crossbeam 8 acts as an "electrical hub," bringing the equipment tray 10 closer to the battery and main cable clamp 6, shortening the high-voltage harness length, and reducing power loss and electromagnetic interference.
[0018] It also includes a flat plate 11, which is hinged to the tail end of the upper beam 3, and a latch 12 is provided between the front end of the upper beam 3 and the flat plate 11.
[0019] In this setup, the flat panel 11 acts as an "openable cover," allowing it to flip upwards to directly expose the battery tray 5, equipment panel 16, or main cable clamp 6 below. This allows for electrical system inspection and maintenance without disassembling the entire cargo box or chassis cover.
[0020] It also includes a branch cable clamp 13 disposed on one side of the rear crossbeam 9. It also includes a converter bracket 14, which is fixedly disposed on one side of the upper beam 3.
[0021] Branch cable clamps are used for 13-point conduit branch lines, such as low-voltage harnesses like taillights, turn signals, and brake signal lines, to prevent them from getting tangled with high-voltage lines, reduce signal misjudgment caused by electromagnetic interference, and facilitate quick location of faulty lines without the need for a full line inspection.
[0022] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
