[0001] The utility model relates to the technical field of inner tube wiring structures, in particular to an inner tube wiring structure of an electric tricycle. Background Art

[0002] Traditionally, the power cords of electric tricycles are fixed by welding wire clips on the outer surface of the center beam. However, this fixing method has certain safety hazards. It is very easy for the power cord to fall or become disconnected after the electric tricycle touches the chassis during driving, which poses certain risks.

[0003] After searching in the publication (announcement) number: CN219487627U, a wiring structure of the inner tube of the center beam of an electric tricycle is disclosed, including a center beam located on the electric tricycle, the outer side surface of the center beam is recessed inward along the length direction to form a mounting groove, the inner upper and lower surfaces of the mounting groove are slidingly provided with a wire pressing stopper strip, the outer walls on both sides of the wire pressing stopper strip are provided with limiting teeth, the inner walls on both sides of the mounting groove are provided with tooth grooves, and the limiting teeth and the tooth grooves are meshed with each other; the wiring harness of the electric tricycle is directly inserted into the mounting groove of the center beam, and the wire pressing stopper strip is pressed into the mounting groove to prevent the wiring harness from falling out, and the wire pressing stopper strip is engaged with the tooth groove of the mounting groove with the limiting teeth, so as to further enhance the connection stability between the wire pressing stopper strip and the mounting groove, realize the protection of the wiring harness, and avoid the wiring harness damage or breakage caused by the chassis scraping against obstacles when the electric tricycle encounters a rugged road during driving, thereby providing safety protection for subsequent use.

[0004] Although the above solution prevents the wiring harness from being damaged or broken due to the chassis scraping against obstacles when the electric tricycle encounters rough roads during driving, it is not convenient enough when fixing the wiring harness. If the wiring harness does not move inside the center beam, the wiring harness can only be pulled out and reinserted, and multiple wiring harnesses are prone to loosening when one end is fixed together. Utility Model Content

[0005] The main purpose of the utility model is to provide an inner tube wiring structure for an electric tricycle. By providing a disassembly unit, the problem that the wiring harness is not convenient enough when being fixed, if the wiring harness does not move inside the center beam, the wiring harness can only be pulled out and reinserted is solved. By providing a limiting unit, the problem that one end of multiple wiring harnesses is easy to loosen when being fixed together is solved.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

Since the receiving component and the connecting component have the same structure, and the receiving component and the fitting plate and the partition plate in the connecting component are fitted, the inside of the center beam is divided into multiple placement grooves, which can be used to place different wiring harnesses. The elastic force of the first elastic column and the first spring can also be used to drive the push plate to limit the activity space of the wiring harness, thereby improving the convenience of fixing the wiring harness. If the wiring harness does not move during the insertion process, it is only necessary to remove multiple locking bolts and then drive the metal plate to separate from the center beam, so that the wiring harness can be arranged and continued to be pushed in, so there is no need to pull out the wiring harness and re-insert it.

[0018] 2. In the utility model, through the setting of the limiting unit, when multiple wire harnesses enter the curved beam, one end of the multiple wire harnesses are connected to the connecting block, and the elastic force of the second elastic column and the second spring drives the arc plate to squeeze the multiple wire harnesses, so that the multiple wire harnesses are controlled between the two flexible blocks, thereby improving the stability of the fixation of the multiple wire harnesses.
