Description

Technical Field

[0001] The invention relates to the technical field of electrical components, in particular to a conductive roller structure and accessories thereof. Background Art

[0002] The conductive roller structure and its accessories are usually used in generators. When the generator is working, the conductive roller rotates to drive the conductive ring to rotate, and the current flows into the carbon brush through the conductive roller and the conductive ring, thereby transferring the current to the static external circuit. The contact resistance between the conductive ring and the carbon brush is inversely proportional to the contact area and contact force between the two. The greater the contact resistance, the more heat is generated.

[0003] In the prior art, the outer wall of the conductive ring is usually a smooth curved surface, and the contact area between the conductive ring and the carbon brush is often small, resulting in a large contact resistance. Patent CN219304130U discloses a long-life small carbon brush spring-type conductive slip ring. Among them, the outer wall of the conductive slip ring is a smooth curved surface, and the end face of the carbon brush in contact with the conductive slip ring is a flat surface, resulting in a large contact resistance between the two, affecting the current transmission effect.

[0004] In addition, during the relative rotation of the conductive ring and the carbon brush, the carbon brush will produce different degrees of wear, resulting in changes in the contact resistance between each carbon brush and the conductive ring, uneven current distribution, and thus affecting the overall working efficiency of the equipment. At the same time, the contact resistance of each carbon brush is uneven, resulting in uneven heat generation of the contact resistance on each carbon brush, which may cause local overheating and increase safety hazards. Summary of the invention

[0005] One object of the present invention is to reduce the contact resistance between the conductive ring and the first carbon block, thereby reducing the current transmission loss and improving the current transmission effect of the conductive roller structure and its accessories.

[0010] Furthermore, two conductive rings located at two ends of the conductive roller are fixed relative to the conductive roller, and the remaining conductive rings move along the axial direction of the conductive roller under the pressure of the first carbon block.

The contact force on each conductive ring reaches a relatively balanced state, thereby reducing the unevenness of the contact force between each conductive ring and each first carbon block. Local overheating caused by excessive contact resistance in a certain area is avoided, the risk of fire is reduced, and safety hazards are reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Refer to the following Figures 1 to 12 To describe a conductive roller structure and its accessories provided by the present invention.

[0027] This embodiment first provides a conductive roller structure and its accessories. The conductive roller structure and its accessories generally may include: a housing 100 , a conductive roller 200 , a plurality of conductive rings 300 and a plurality of first carbon blocks 400 .

[0028] The conductive roller 200 is rotatably disposed in the housing 100. A plurality of conductive rings 300 are sleeved on the conductive roller 200 and are spaced apart along the axial direction of the conductive roller 200. The outer ring of each conductive ring 300 is formed with a wedge-shaped surface 310 protruding outward. A plurality of first carbon blocks 400 are disposed on the outer periphery of the conductive roller 200, and the shape of the side wall surface of each first carbon block 400 is adapted to the wedge-shaped surface 310 of the adjacent conductive ring 300. At least one first carbon block 400 is disposed between every two adjacent conductive rings 300. The two side wall surfaces of each first carbon block 400 are respectively in contact with the wedge-shaped surfaces 310 of the two adjacent conductive rings 300.

[0029] In the solution of this embodiment, the outer ring of the conductive ring 300 is set to be a wedge-shaped surface 310 protruding outward, and the shape of the side wall surface of the first carbon block 400 is set to match the wedge-shaped surface 310 of the adjacent conductive ring 300, so that the two side wall surfaces of the first carbon block 400 are respectively in contact with the wedge-shaped surfaces 310 of the two adjacent conductive rings 300 to form an inclined contact surface. The inclined setting of the contact surface between the conductive ring 300 and the first carbon block 400 increases the contact area between the conductive ring 300 and the first carbon block 400, thereby reducing the contact resistance, reducing the transmission loss of the current, and improving the current transmission effect of the conductive roller structure and its accessories.

[0030] In the solution of this embodiment, the first carbon block 400 is arranged to contact the conductive ring 300, and the first carbon block 400 is used for conducting electricity, which not only has good conductivity but also has excellent lubricity and current collecting performance, thereby improving the overall working efficiency of the conductive roller structure and its accessories.

[0031] In some embodiments, the length of the first carbon block 400 (along the circumferential direction of the conductive ring 300) can be set to gradually decrease from the bottom surface close to the axis of the conductive ring 300 to the top surface, so that the end surface of the first carbon block 400 has a certain inclination angle. When the first carbon block 400 and the conductive ring 300 are in contact and relatively rotated, the end surface of the first carbon block 400 can scrape off the oil on the conductive ring 300 and discharge it along the end surface in a direction away from the conductive roller 200, thereby avoiding the oil attached to the wedge surface 310 of the conductive ring 300 to affect the conductive effect, and ensuring the normal operation of the conductive roller structure and its accessories.

[0032] The conductive roller structure and its accessories may generally further include at least one mounting plate 110 and a plurality of pressing assemblies 500 .

[0033] At least one mounting plate 110 is disposed on the housing 100. A plurality of pressing assemblies 500 are disposed on at least one mounting plate 110 at intervals along the axial direction of the conductive roller 200. Each first carbon block 400 is connected to a pressing assembly 500 and moves along the radial direction of the conductive roller 200 driven by the pressing assembly 500.

[0034] The solution of this embodiment is to set a mounting plate 110 on the shell 100, and then set a clamping assembly 500 on the mounting plate 110, and use the clamping assembly 500 to drive the first carbon block 400 to move radially along the conductive roller 200, so that the first carbon block 400 can be close to the conductive ring 300, thereby reducing the contact resistance between the first carbon block 400 and the conductive ring 300, and further reducing the energy loss of current transmission.

[0035] In some preferred embodiments, a plurality of mounting plates 110 may be mounted on the housing 100, and the plurality of mounting plates 110 are evenly distributed around the conductive roller 200. A certain number of clamping assemblies 500 are disposed on each mounting plate 110. The plurality of clamping assemblies 500 drive the plurality of first carbon blocks 400 to jointly extrude the conductive ring 300, which not only increases the contact force between the first carbon block 400 and the conductive ring 300, reduces the contact resistance between the first carbon block 400 and the conductive ring 300, but also ensures the coaxiality of the conductive ring 300 and the conductive roller 200, thereby improving the operational reliability of the conductive roller structure and its accessories.

[0036] In some embodiments, the end surface of the first carbon block 400 facing the conductive roller 200 may be an arc-shaped surface, and the curvature of the arc-shaped surface is consistent with the curvature of the side wall surface of the conductive roller 200. Even if the first carbon block 400 is pressed to contact the side wall of the conductive roller 200, it can ensure that the first carbon block 400 and the conductive roller 200 are well attached and have a good conductive effect.

[0037] The pressing assembly 500 may generally include: a fixing block 510 , two first hinges 520 , a first tension spring 530 , and a first conductive belt 540 .

[0038] The fixing block 510 is disposed on the mounting plate 110. Two first hinges 520 are symmetrically disposed on the fixing block 510, and the two first hinges 520 are respectively hinged to two adjacent first carbon blocks 400 located on the same loop line. The first tension spring 530 is disposed between the two first hinges 520, and its two ends are respectively connected to the two first hinges 520. The first conductive belt 540 is disposed between the fixing block 510 and the mounting plate 110, and the two ends of the first conductive belt 540 are respectively connected to two adjacent first carbon blocks 400 located on the same loop line.

[0039] like Fig.10 As shown, each pressing assembly 500 is provided with two adjacent first carbon blocks 400 located on the same loop line. The two symmetrical first hinges 520 form a V shape under the tension of the first tension spring 530, driving the two first carbon blocks 400 to press tightly against the conductive ring 300, thereby increasing the contact force between the first carbon block 400 and the conductive ring 300, and further reducing the contact resistance between the first carbon block 400 and the conductive ring 300.

[0040] In the solution of this embodiment, both ends of the first conductive belt 540 are respectively connected to the two first carbon blocks 400, so that the current on the first carbon block 400 flows to the conductive belt, realizing smooth transmission of current from the rotating conductive roller 200 to the stationary external circuit.

[0041] In some embodiments, the first hinged member 520 can be configured in an I-shape, consisting of two hinged rods and a connecting rod located between the two hinged rods. The two hinged rods are symmetrically arranged, one end of which is symmetrically hinged on the two side walls of the fixed block 510, and the other end of which is symmetrically hinged on the two side wall surfaces of the first carbon block 400.

[0042] In some embodiments, the fixing block 510, the mounting plate 110 and the housing are all conductive, and current can flow through the first conductive tape 540, the fixing block 510, the mounting plate 110, etc. to the conductive plate installed on the mounting plate 110, and output current through the conductive plate.

[0043] In other embodiments, the first conductive strip 540 may be directly connected to a stationary external circuit to output current.

[0044] The two conductive rings 300 located at both ends of the conductive roller 200 are fixed relative to the conductive roller 200 , and the remaining conductive rings 300 move along the axial direction of the conductive roller 200 under the pressure of the first carbon block 400 .

[0045] like Fig.11 As shown, the conductive ring 300 and the first carbon block 400 are arranged alternately, and the first carbon block 400 is abutted on both sides of each conductive ring 300. When the tension of the first tension spring 530 applied to the first carbon block 400 on one side of the conductive ring 300 is too large, the first carbon block 400 will move radially inward, and at the same time push the conductive ring 300 to move axially to the other side, thereby squeezing the first carbon block 400 on the other side to move radially outward. During the movement of the conductive ring 300, the first carbon block 400 on one side of the conductive ring 300 gradually approaches the conductive roller 200 in the radial direction, and the tension applied to it gradually decreases; the first carbon block 400 on the other side of the conductive ring 300 gradually moves away from the conductive roller 200 in the radial direction, and the tension applied to it gradually increases. After the mechanical states of the conductive ring 300 and the first carbon blocks 400 on both sides of the conductive ring 300 reach a relative balance, the conductive ring 300 stops moving. At this time, the difference in contact force between the first carbon block 400 and the conductive ring 300 on both sides of the conductive ring 300 has been narrowed, avoiding the excessive contact resistance caused by the contact force between a first carbon block 400 and the conductive ring 300 being too small, avoiding local overheating, reducing the risk of fire, and reducing safety hazards.

[0046] In addition, during the movement of the conductive ring 300, the change in contact resistance caused by the change in the contact force of the first carbon block 400 is small, and the change in its resistance heat generation is also small. The change in the heat generation of the first carbon block 400 mainly comes from friction heat generation. After the conductive ring 300 stops moving, due to the friction resistance on the conductive ring 300 and the first carbon block 400, the contact force between the first carbon block 400 and the conductive ring 300 radially close to the conductive roller 200 is actually greater than the contact force between the first carbon block 400 and the conductive ring 300 on the other side. Therefore, during the movement of the conductive ring 300, until the conductive ring 300 stops moving, the heat generation of the first carbon block 400 close to the conductive roller 200 is always greater than the heat generation of the first carbon block 400 on the other side away from the conductive roller 200. The first carbon block 400 with greater contact force approaches the conductive roller 200, pushing the conductive ring 300 to move to the other side, causing the gap where the first carbon block 400 with greater contact force is located to become larger. Its improved heat dissipation efficiency just neutralizes its higher heat generation, thereby improving operational reliability.

[0047] In the solution of this embodiment, except for the conductive rings 300 at both ends, the other multiple conductive rings 300 can move freely under the pressure of the first carbon block 400, so that the conductive rings 300 can automatically adjust the corresponding positions according to the size of the pressure. The contact force on each conductive ring 300 can reach a relatively balanced state, thereby reducing the unevenness of the contact force between each conductive ring 300 and each first carbon block 400. It avoids local overheating caused by excessive contact resistance in a certain area, reduces the risk of fire, and reduces safety hazards.

[0048] The solution of this embodiment improves the uniformity of the contact force between each conductive ring 300 and each first carbon block 400, so that the contact resistance between each conductive ring 300 and the first carbon block 400 is not much different, thereby reducing the overall total heat generation of each conductive ring 300 and each first carbon block 400, which not only reduces the fire risk of the conductive roller structure and its accessories, but also avoids the increased wear of the conductive ring 300 and the first carbon block 400, thereby ensuring the service life of the conductive roller structure and its accessories.

[0049] The conductive roller 200 is provided with a plurality of grooves 210, and a plurality of supporting assemblies 600 are provided in the plurality of grooves 210. Each supporting assembly 600 is connected to a conductive ring 300. The plurality of supporting assemblies 600 support the plurality of conductive rings 300, so that the plurality of conductive rings 300 rotate under the drive of the conductive roller 200.

[0050] like Figure 2 As shown, a plurality of grooves 210 are disposed on the conductive roller 200 , and the grooves 210 are formed extending from one end of the conductive roller 200 to the other end.

[0051] The inner side of the conductive rings 300 at both ends may be formed with inwardly protruding blocks 320, which are inserted into the corresponding grooves 210, so that the conductive rings 300 are driven by the conductive roller 200 to rotate. A plurality of support assemblies 600 are arranged in the groove 210, and the plurality of support assemblies 600 are connected to a plurality of conductive rings 300 except the two ends. Except for the conductive rings 300 at the two ends, each conductive ring 300 is connected to at least one support assembly 600. When the conductive roller 200 rotates, the conductive rings 300 are driven to rotate together through the support assemblies 600.

[0052] In some embodiments, bolts may be provided on the blocks 320 of the conductive ring 300 at both ends to fix them on the conductive roller 200 .

[0053] like Figure 6-7 As shown, the support components 600 support the conductive rings 300 in the grooves 210 at intervals to avoid interference between adjacent support components 600. The support components 600 in two opposite grooves 210 are staggered, thereby supporting all conductive rings 300 while avoiding interference between the support components 600.

[0054] In some preferred embodiments, the plurality of grooves 210 are evenly arranged in the circumferential direction of the conductive roller 200 to improve the overall structural stability of the conductive roller 200 and the conductive ring 300 sleeved on the conductive roller 200 .

[0055] The support assembly 600 may generally include: a support block 610 , two second hinges 620 , a second tension spring 630 , two second carbon blocks 640 , and a second conductive tape 650 .

[0056] The support block 610 is arranged on the inner side of the conductive ring 300. The two second hinges 620 are symmetrically arranged on the support block 610. The second tension spring 630 is arranged between the two second hinges 620, and its two ends are respectively connected to the two second hinges 620. The two second carbon blocks 640 are arranged in the groove 210 and are respectively hinged to the two second hinges 620. The second conductive belt 650 is arranged between the support block 610 and the conductive ring 300, and the two ends of the second conductive belt 650 are respectively connected to the two second carbon blocks 640.

[0057] The solution of this embodiment uses a tension spring to pull the two second hinges 620, so that the support block 610 is pressed tightly against the inner side of the conductive ring 300, and the structure is simple and stable. The second carbon block 640 and the conductive belt are provided to better guide the current on the conductive roller 200 to the conductive ring 300 while completing the supporting function of the conductive ring 300, thereby ensuring the current transmission effect. In addition, the conductive ring 300 will move axially under the pressure of the first carbon block 400. The provision of the second carbon block 640 not only ensures the conductive effect of the support assembly 600, but also has a good lubrication effect, so that the support assembly 600 can move smoothly along the groove 210 driven by the conductive ring 300 while holding the conductive ring 300 tightly.

[0058] In some embodiments, the second hinge member 620 may be configured in an I-shape, consisting of two hinge rods and a connecting rod located between the two hinge rods.

[0059] The conductive roller structure and its accessories may generally also include a plurality of cleaning components 700 .

[0060] The cleaning assemblies 700 are disposed on the outer peripheries of the conductive rings 300 and correspond to the conductive rings 300 one by one, and are used to remove oil stains on the wedge surfaces 310 of the conductive rings 300 .

[0061] During the operation of the conductive roller structure and its accessories, oil stains may adhere to the wedge surface 310 of the conductive ring 300. The oil stains adhere to the wedge surface 310 to form an insulating layer, which increases the contact resistance between the conductive ring 300 and the first carbon block 400, thereby reducing the conductive properties of the conductive ring 300 and the first carbon block 400 and affecting the normal operation of the equipment.

[0062] The solution of this embodiment is to set up cleaning components 700 corresponding to the conductive rings 300 one by one, so as to clean the oil stains on the wedge-shaped surface 310 of each conductive ring 300, thereby avoiding the oil stains adhering to the wedge-shaped surface 310 of the conductive ring 300 and affecting the conductive effect, thereby ensuring the normal operation of the conductive roller structure and its accessories.

[0063] The cleaning assembly 700 may generally include a clip 710 and a support rod 720 .

[0064] The clip 710 is clamped on the wedge-shaped surface 310 of the conductive ring 300, and is used to scrape off the oil stains on the wedge-shaped surface 310 of the conductive ring 300 when the clip 710 and the conductive ring 300 rotate relative to each other. The support rod 720 is connected to the clip 710, and is used to support the clip 710.

[0065] The solution of this embodiment is to provide a V-shaped clip 710, so that the clip 710 is clamped on the conductive ring 300, and the oil stains attached to the wedge-shaped surface 310 of the conductive ring 300 are scraped off by the rotation of the conductive ring 300. Not only is the structure simple, but the decontamination effect is stable. The clip 710 is supported by the support rod 720, so that the clip 710 can better fit the conductive ring 300 and be closely attached to the wedge-shaped surface 310 of the conductive ring 300, further improving the cleaning effect of the clip 710.

[0066] In some preferred embodiments, the clip 710 may be composed of two leaves connected by a torsion spring, and the elastic force of the torsion spring is used to make the clip 710 close to the conductive ring 300, thereby ensuring the decontamination effect.

[0067] In some preferred embodiments, the blades of the clip 710 are configured to be wider at the portion close to the axis of the conductive ring 300 and narrower at the portion away from the axis of the conductive ring 300. That is, the blades of the clip 710 form a shape similar to an inverted triangle. When the conductive ring 300 rotates, the oil stains on the wedge surface 310 move along the side wall of the clip 710 in a direction away from the axis of the conductive ring 300, thereby scraping off the oil stains and preventing the oil stains from flowing to the conductive roller 200 and causing secondary pollution.

[0068] In some embodiments, the support rod 720 is configured as a retractable rod to ensure that the clamp 710 can clamp the wedge surface 310 of the conductive ring 300, thereby improving the decontamination effect.

[0069] A slide groove 120 is disposed at the bottom end of the housing 100, and the length direction of the slide groove 120 is consistent with the axial direction of the conductive roller 200. The support rod 720 is disposed in the slide groove 120 so as to be movable along the length direction of the slide groove 120.

[0070] In some embodiments, the conductive ring 300 can move along the axial direction of the conductive roller 200. By setting a slide groove 120 whose length direction is consistent with the axial direction of the conductive roller 200, and allowing the support rod 720 to move along the length direction of the slide groove 120, when the conductive ring 300 moves axially, the support rod 720 can move accordingly with the wire ring, ensuring that the clip 710 can always be clamped on the wedge surface 310 of the conductive ring 300, thereby ensuring the decontamination effect. In addition, the slide groove 120 can also collect the oil scraped off by the clip 710, which can not only prevent the oil from contaminating the housing 100, but also facilitate cleaning.

[0071] In some embodiments, the housing 100 may be provided with one or more openings to facilitate the exchange of hot and cold air inside and outside the housing 100 to dissipate heat from the conductive roller 200 .

[0072] The conductive roller structure and its accessories may generally further include an exhaust chamber 800 .

[0073] The exhaust chamber 800 is disposed on the housing 100 and located at one end of the conductive roller 200 , and is used to extract air around the conductive roller 200 .

[0074] In the solution of this embodiment, an exhaust chamber 800 is provided at one end of the conductive roller 200 , and the exhaust chamber 800 is used to extract the air around the conductive roller 200 , thereby increasing the flow rate of the air around the conductive roller 200 and improving the heat dissipation efficiency.

[0075] In some embodiments, an air pump may be disposed in the air pumping chamber 800 , or the air pumping chamber 800 may be directly connected to the air pump.

[0076] In some preferred embodiments, the vacuum chamber 800 can be set at one end of the groove 210, so that the air around the conductive roller 200 can flow through the first carbon block 400 and the conductive ring 300 and then flow into the vacuum chamber 800 through the groove 210, making the air flow smoother, thereby further improving the heat dissipation efficiency.

[0077] The specific working process of the conductive roller structure and its accessories provided by the present invention is described in combination with the above embodiments: The conductive roller 200 starts to rotate, driving the conductive ring 300 to rotate through the support assembly 600. Under the pressure of the pressing assembly 500, the first carbon block 400 abuts against the wedge surface 310 of the conductive ring 300, and the conductive ring 300 and the first carbon block 400 rotate relative to each other. The current on the conductive roller 200 is transmitted to the conductive ring 300 through the support assembly 600, and then transmitted to the first carbon block 400, and then transmitted to the static external circuit.

[0078] During the relative rotation of the conductive ring 300 and the first carbon block 400, each first carbon block 400 is worn to different degrees, so that the contact force between each first carbon block 400 and the corresponding conductive ring 300 changes to different degrees. Due to the change of the contact force between each first carbon block 400 and each conductive ring 300, each conductive ring 300 moves axially under the pressure of each first carbon block 400 until each conductive ring 300 and each first carbon block 400 reach a balanced state again. During the axial movement of the conductive ring 300, the cleaning assembly 700 slides accordingly with the axial movement of the conductive ring 300, so that the clip 710 of the cleaning assembly 700 is always clamped on the wedge surface 310 of the corresponding conductive ring 300 to scrape off the oil stains on the wedge surface 310.

[0079] Each conductive ring 300 adjusts its position in real time according to the actual situation, so that each conductive ring 300 and each first carbon block 400 can always be in a relatively balanced state, thereby reducing the unevenness of the contact force between each conductive ring 300 and each first carbon block 400. Not only does it avoid local overheating and causing fire, but it also reduces the overall total heat generation of each conductive ring 300 and each first carbon block 400, further reducing safety hazards and ensuring the service life of the conductive roller structure and its accessories.

[0080] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
