Description

Technical Field

[0001] This utility model relates to the field of conductive technology, and in particular to a sliding conductive structure. Background Technology

[0002] In many fields such as industrial production and children's toys, it is often necessary to ensure the stable operation of mobile devices on tracks while maintaining a continuous power supply. For example, in the rail drive scenario of a production line, mobile tooling needs to reciprocate along the track to complete operations such as material transfer and processing; during the operation of a children's conductive toy car, the toy car needs to move along a preset track and maintain electric drive.

[0003] However, traditional power supply methods for mobile devices have significant limitations. Wired connections are prone to dragging and tangling as the device moves, limiting its mobility and flexibility. Worn wires can also cause short circuits and power outages, posing safety hazards, especially in children's toys where these risks are more pronounced. Battery power avoids wiring issues, but requires regular replacement or charging, increasing maintenance costs and operational complexity. Furthermore, battery capacity is limited and cannot meet the demands of long-term, continuous operation.

[0004] To address these issues, the industry has gradually explored track-based conductive technology, which transmits power through conductive contact between mobile devices and the track. However, in existing track-based conductive structures, the contact stability between moving parts and the conductive track is poor, easily leading to poor contact and interruption of conductivity due to factors such as vibration and gap changes. Furthermore, in some structures, the rolling and sliding fit design of moving parts is unreasonable, resulting in high resistance to movement and rapid wear, affecting conductivity efficiency and structural lifespan. In addition, the complex assembly relationships of existing structures and insufficient coordination between fixed and moving parts further limit their reliable application in various scenarios.

[0005] Therefore, developing a sliding conductive structure that can achieve stable contact between moving parts and fixed conductive tracks, reliable conductivity, and smooth movement has become a key requirement for solving the current power supply problem of mobile devices. Utility Model Content

[0006] In view of this, the present invention provides a sliding conductive structure, which aims to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A sliding conductive structure includes a fixed component and a movable component. The fixed component includes an insulator and a conductive copper strip, the conductive copper strip being fixedly disposed on one side of the insulator and having a positive end and a negative end. The movable component includes a support frame, a copper sleeve fixing ring, a copper conductive pulley, and a conductive spring. The copper sleeve fixing ring is fixedly disposed on the conductive spring, and the copper conductive pulley is sleeved on the outer periphery of the copper sleeve fixing ring, with the copper conductive pulley and the copper sleeve fixing ring rotating in engagement. One end of the conductive spring abuts against the support frame, and the other end is connected to the copper conductive pulley, the spring force of which causes the copper conductive pulley to be in close contact with the conductive copper strip. The movable component can slide relative to the fixed component along the length direction of the conductive copper strip, and the copper conductive pulley and the conductive copper strip achieve conductivity through sliding contact.

[0009] Preferably, the conductive copper strip includes a positive copper strip and a negative copper strip, which are arranged parallel to each other and spaced apart, and are both fixedly arranged on the side of the insulator facing the moving component.

[0010] Preferably, the number of copper conductive pulleys is the same as the number of conductive copper strips, and each copper conductive pulley is in close contact with one of the conductive copper strips; the number of copper sleeve fixing rings is the same as the number of copper conductive pulleys, and each copper conductive pulley is fitted onto the outer periphery of one of the copper sleeve fixing rings.

[0011] Preferably, the outer peripheral wall of the copper conductive pulley can fit against the surface of the conductive copper strip, and the copper conductive pulley can rotate around the axis of the copper sleeve fixing ring.

[0012] Preferably, the moving component further includes an external force driving component, which is connected to the support frame and is used to drive the moving component to move left and right relative to the fixed component along the length direction of the conductive copper strip.

[0013] Preferably, the insulator is rigidly fixed to an external fixed base, and the insulator serves as a static reference, with the moving component sliding relative to the insulator as a reference.

[0014] Compared with existing technologies, a sliding conductive structure has the following positive effects:

[0015] This design eliminates the risks of dragging and tangling associated with wired connections, as well as safety hazards such as short circuits and power outages caused by wire wear (especially suitable for safety-critical scenarios like children's toys). Furthermore, it eliminates the need for battery replacement or charging, completely resolving the cumbersome maintenance issues of battery-powered systems, meeting the demands of long-term, continuous operation, and reducing operating costs. The conductive spring's elasticity is consistently applied to the copper conductive pulley, ensuring a tight fit between the pulley and the conductive copper strip even under conditions of equipment vibration, minor gaps in the track, or assembly errors. This fundamentally solves the problem of "unstable contact and interrupted conductivity," significantly improving conductivity reliability. The rolling fit between the copper conductive pulley and the copper sleeve fixing ring greatly reduces frictional resistance when the moving component slides relative to the fixed component, minimizing component wear. Simultaneously, the brass material of the copper conductive pulley provides excellent wear resistance and conductivity, further extending the structure's lifespan and improving smoothness of movement.

[0021] The technical solutions in the embodiments of this utility model are described clearly and completely below. 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.

[0022] like Figure 1-3As shown, this embodiment discloses a sliding conductive structure, including a fixed component and a moving component. Stable conductivity is achieved during movement through the cooperation of the fixed and moving components. The fixed component includes an insulator 1 and a conductive copper strip 2. The insulator has good insulation performance and structural strength, effectively preventing short circuits between the conductive components and external structures. The insulator 1 is rigidly fixed to an external fixed base (such as a production line frame or toy track support) by bolts, serving as a static reference for the entire structure, ensuring the stability of the fixed component, and providing a reliable sliding reference for the moving component. This solves the problem of insufficient fitting accuracy caused by the easy loosening of fixed components in existing structures.

[0023] The conductive copper strip 2 is made of high-purity copper, exhibiting excellent conductivity. It is fixed to the side of the insulator 1 facing the moving component by bolts or welding. In this embodiment, the conductive copper strip 2 includes a positive copper strip and a negative copper strip, both being elongated plate-like structures, parallel to each other and spaced apart. This spacing design effectively prevents short circuits between the positive and negative electrodes while ensuring accurate contact between the conductive components of the moving component. One end of the positive copper strip is connected to the positive terminal of an external power source, and one end of the negative copper strip is connected to the negative terminal of the external power source, forming a complete conductive circuit.

[0024] The moving component includes a support frame 3, a copper sleeve fixing ring 4, a copper conductive pulley 5, a conductive spring 6, and an external force driving component.

[0025] The support frame 3 is made of aluminum alloy, which is lightweight and has high structural strength. It serves as the mounting base for the movable components and is used to support other parts.

[0026] The copper sleeve fixing ring 4 is a ring structure made of brass, which has good conductivity and wear resistance. It is fixed in the preset mounting hole of the support frame 3 by interference fit, which is firm and has high positional accuracy, ensuring the assembly stability of subsequent components.

[0027] The copper conductive pulleys 5 are also made of brass, and their number is the same as that of the conductive copper strips 2. Each copper conductive pulley 5 is fitted one-to-one with the outer circumference of a copper sleeve fixing ring 4, and the copper conductive pulley 5 is fitted with the copper sleeve fixing ring 4 with a gap, so that the copper conductive pulley 5 can rotate flexibly around the axis of the copper sleeve fixing ring 4. The outer peripheral wall of the copper conductive pulley 5 is designed with an arc-shaped structure that matches the surface of the conductive copper strip 2, so that it can fit tightly with the surface of the conductive copper strip 2, ensuring the conductive contact area and improving the conductivity reliability. At the same time, the rolling fit design significantly reduces the moving resistance compared with the traditional sliding contact, reduces component wear, and extends the service life of the structure.

[0028] The conductive springs 6 are metal springs with good conductivity, and their number is the same as that of the copper conductive pulleys 5. Each conductive spring 6 is fitted around the outer periphery of the corresponding copper sleeve fixing ring 4. One end of the conductive spring 6 abuts against the support frame 3, and the other end abuts against the side of the copper conductive pulley 5. Through its own elastic force, it continuously applies pressure to the copper conductive pulley 5, ensuring that the copper conductive pulley 5 is always in close contact with the conductive copper strip 2. Even under equipment vibration or minor assembly errors, the elastic force of the conductive spring 6 can automatically compensate for gaps, effectively avoiding conductivity interruption caused by poor contact and significantly improving conductivity stability.

[0029] This structure solves the problems of dragging and tangling in traditional wired power supply and the maintenance difficulties of battery power supply. It also improves conductivity stability and smoothness of movement through elastic compression and rolling contact design. It has the advantages of simple structure, high reliability and long service life, and can be widely used in various scenarios such as industrial production and children's toys.

[0030] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
