Description

Technical Field

[0001] This utility model relates to the field of handlebars, and more particularly to an electrically adjustable temperature handlebar with a fixed wire. Background Technology

[0002] Currently, for heated handles of various shapes used in electric vehicles, motorcycles, snowmobiles, all-terrain vehicles, motorboats, tricycles, and four-wheeled vehicles, the traditional throttle handle's temperature adjustment function often uses a front-mounted reset spring structure. This can easily cause the wires to become tangled or even damaged as the throttle rotates. Some designs use springs for conductivity, such as the Chinese invention patent CN102393787B, entitled "Spring-Powered Multifunctional Handlebar." This design includes a moving body, a handlebar tube, and a fixed body. The fixed body is fixedly mounted on the handlebar tube, and the moving body is mounted on the handlebar tube and can rotate relative to it. A temperature-regulating element is located within the moving body. The moving body and the fixed body are connected by at least one spring, and the temperature-regulating element is led out and conductive through a lead wire connected to the spring. The moving body and the fixed body on the handlebar tube are connected by at least one spring, which acts as a bridge for power transmission between the moving body and the power source. However, this structure has the following drawbacks: the front-mounted spring results in excessive thickness; the return spring is located at the front of the handlebar, requiring additional space and increasing the overall thickness of the handlebar; it is incompatible with the mounting slots of some vehicle models; the traditional fixing ring protrudes from the front of the cover, requiring a groove of a specific depth for installation, making it difficult to adapt to vehicles with flat or shallow grooves; and the spring's conductivity reliability is low: some existing technologies achieve heating by directly conducting electricity through the spring, which is prone to conductivity failure due to spring fatigue or poor contact after long-term use. Based on these issues, this invention proposes an electrically adjustable temperature handlebar with fixed wires, a rear-mounted spring, and a compact structure to solve the above problems. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing an electrical temperature control handle with a fixed wire.

[0004] To solve the above-mentioned technical problems, this utility model achieves its solution through the following technical solution:

[0005] An electrical temperature control handle with a fixed wire includes a base, a rotating sleeve, a return spring, and a temperature control assembly. The base includes a fixed cover with a retaining ring at its front end for connection to a switch assembly; the rotating sleeve is fitted over the base and can rotate circumferentially relative to the base; the return spring is connected to both the base and the rotating sleeve for rotating and resetting the sleeve; the temperature control assembly includes a temperature control element and a wire, with the temperature control element located on the outer periphery of the base and the inner side of the rotating sleeve.

[0006] The wire has a fixed section for connecting to the power supply and a movable section for connecting to the temperature control element. A limiting seat is set inside the fixed housing. The fixed section is wound inside the fixed housing and fixed to the limiting seat by snap-fit ​​or fixed connection. A channel is set on the side of the fixed housing near the rotating sleeve. The movable section passes through the channel and coils or straightens as the rotating sleeve rotates. The wire is designed with separate fixing and movement: the fixed section is fixed by the limiting seat to avoid pulling, and the movable section is guided by the channel, so that only the small section of the wire adjacent to the temperature control element moves with the rotation of the handle. The end connected to the main control is fixed in the fixed housing, and the part outside the fixed housing will not be pulled, which can reduce the tangling or wear of the wire caused by rotation. Because the spring is changed from front to rear, and the fixing ring does not protrude from the front of the fixed housing, the fixed housing part is much thinner than the handle of the existing technology. It can be matched and installed regardless of whether the switch assembly and the handle are connected to a flat surface or a protruding frustum.

[0007] Preferably, the wires are connected to the temperature control element by riveting or welding. This avoids problems such as poor contact or increased resistance, and improves the stability of heating or cooling.

[0008] Preferably, the front center of the fixed cover has a mounting groove, and the fixing ring is fitted into the mounting groove. The fixing ring is recessed inward relative to the mounting groove, and the front face of the fixing ring does not exceed the front face of the fixed cover. The embedded fixing ring reduces the overall thickness, making it suitable for flat-mouth or shallow-groove vehicle models and improving versatility.

[0009] Preferably, the front end of the fixed cover is provided with a first guide groove, which is located on the outer ring of the mounting groove. The space inside the first guide groove is connected to the channel, and the space inside the first guide groove allows the moving section to be coiled or straightened within it. The double guide groove design guides the movement path of the wire and avoids breakage caused by disordered coiling.

[0010] Preferably, the front end of the fixed cover is provided with a second guide groove, which is connected to or integrated with the first guide groove. The limiting seat is disposed in the second guide groove, and the wire passes through the first guide groove and the second guide groove in sequence before extending out of the fixed cover.

[0011] Preferably, a rear cover is installed at the rear end of the mounting base, and the mounting base and the rear cover are fixed to each other.

[0012] Preferably, a cavity is provided between the mounting base and the back cover.

[0013] The return spring is located inside the cavity, and its two ends are connected to the rotating sleeve, the fixed seat, or the rear cover, respectively.

[0014] Preferably, the return spring is a torsion spring, with one end fixed to the rear end of the fixing base and the other end fixed to the inner wall of the rotating sleeve. The torsion spring structure enables the rotating sleeve to return to its original position.

[0015] Preferably, the temperature regulating element is a resistance wire or a heating wire, which serves to heat the components.

[0016] This utility model, by adopting the above technical solution, has significant technical effects:

[0017] 1. The embedded fixing ring and flat structure design make it suitable for installing handlebars on more vehicle models;

[0018] 2. Enhanced heating reliability: The wire-riveted / welded temperature control element replaces other components for conduction, which can effectively avoid temperature rise and fall failures caused by poor contact;

[0019] 3. The guide groove and the limit seat work together to reduce the need for the wire to remain stationary at the end connected to the main control or power supply, thereby avoiding wire wear and mess and reducing the risk of use;

[0020] 4. The integrated design of the rear-mounted spring and temperature control component significantly reduces the handle thickness, making the structure more compact and easier to install. Attached Figure Description
