Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a current collector to solve the problem that the cable in the current collector easily produces the restraint to the motion of carbon brush. The following description will be made with reference to the accompanying drawings.

In the embodiment of the present application, as shown in fig. 1 and 2, the current collector 10 includes a slider 20, a conductive rotating shaft 30, and a conductive member 40. The sliding contact 20 is provided with an electric conductor 21, the conductive rotating shaft 30 is connected with the sliding contact 20 and is in electric contact with the electric conductor 21, the conductive assembly 40 comprises a wire 45, the wire 45 is provided with a first connection end 451 and a second connection end 452, the first connection end 451 is electrically connected with the conductive rotating shaft 30, and the second connection end 452 is used for being electrically connected with a standby electric device.

Specifically, as shown in fig. 1, the current collector 10 in the embodiment of the present application is mainly used in a trolley line system 100, where the trolley line system 100 generally includes an energized guide rail 110, the energized guide rail 110 is connected with a power supply, the current collector 10 slides in the energized guide rail 110 through a sliding contact 20 to obtain electricity, and the sliding contact 20 is connected with an electrical device to be used through a cable, so as to implement mobile power supply of the electrical device to be used.

As shown in fig. 2 and fig. 3, the sliding contact element 20 in the current collector 10 has a conductive body 21, the conductive body 21 may be in the form of a conductive copper sheet, a conductive block, a conductive roller, etc., and the conductive body 21 is in sliding contact with the electrified guide rail 110 to achieve moving and electricity taking. The conductor 21 is covered with an insulator 22 at the portion exposed from the current-carrying rail 110 to prevent electrical shock or short circuit with an external conductive structure.

Referring to fig. 2, 3 and 6, the conductive shaft 30 of the current collector 10 is connected to the sliding contact element 20, generally in a rotating connection, so that the sliding contact element 20 can swing adaptively when sliding to a position with a convex, a slope or a curved section in the current-carrying rail 110, and thus can keep sliding smoothly. Different from the conventional current collector, the conductive rotating shaft 30 in the embodiment of the present application is conductive and electrically contacts with the conductive body 21 on the sliding contact piece 20, that is, the connection point between the conductive rotating shaft 30 and the sliding contact piece 20 is both a rotating connection point and an electric energy leading-out point, so that not only the structure of the current collector 10 can be simplified, but also the cable for connecting the to-be-used electric device does not need to be directly connected with the sliding contact piece 20, and the electric energy on the sliding contact piece 20 can be transmitted to the to-be-used electric device.

The conductive rotating shaft 30 may be made of a conductive material as a whole, or may be formed by a conductive material only in a part, for example, the shaft center is made of a conductive material, the shaft sleeve outside the shaft center is made of an insulating material, and only the conductive part in the rotating shaft structure needs to be electrically contacted with the conductive body 21 of the sliding contact element 20, and the specific structural form may be designed according to actual conditions. The conductive material is not limited, and the conductive material may be the same as the conductive material used for the conductive body 21, so that the same material is conveniently used for processing, the conductive is stable, and the abrasion can be reduced when the conductive material and the conductive body are rubbed with each other.

In addition, there are various ways of electrical contact between the conductive rotating shaft 30 and the electrical conductor 21, for example, the conductive part of the conductive rotating shaft 30 is rotatably connected to the electrical conductor 21 by a conductive pin, so that the rotation of the electrical conductor 21 is not affected, and the electrical energy on the electrical conductor 21 can be derived. Alternatively, a shaft structure and a hole structure which can be rotatably connected are respectively formed directly on the conductive rotating shaft 30 and the conductive body 21, and the conductive rotating shaft 30 and the conductive body 21 are directly rotatably connected. Or, the conductive body 21 is provided with a cavity, and the conductive rotating shaft 30 partially extends into the cavity of the conductive body 21 and keeps contact with the conductive body 21 without interfering with the rotation of the conductive body 21, and at this time, the rotational connection relationship between the conductive rotating shaft 30 and the sliding contact member 20 can be completed by the insulation part of the two.

As shown in fig. 2, after the electric energy on the electric conductor 21 is transferred to the conductive rotating shaft 30, in order to further derive the electric energy on the conductive rotating shaft 30, the embodiment of the present application further includes a conductive assembly 40, the conductive assembly includes a wire 45, as shown in fig. 1, the wire 45 has a first connection end 451 and a second connection end 452, the first connection end 451 is electrically connected to the conductive rotating shaft 30, and the second connection end 452 is used for electrically connecting to the standby electric device, so as to transfer the electric energy to the standby electric device, thereby implementing mobile power supply of the standby electric device.

For example, the wire 45 may be directly connected to the conductive rotating shaft 30, or based on a design principle that the rotation of the conductive rotating shaft 30 is not affected, the conductive assembly 40 may further include a bearing structure or a similar switching structure, the bearing structure is sleeved outside the conductive rotating shaft 30 (or connected to an end of the conductive rotating shaft 30) and electrically contacts the conductive rotating shaft 30, and the wire 45 is further electrically connected to a non-rotating portion of the bearing structure. Or, the conductive element 40 may further include a conductive block, a conductive pin, etc., which are fixed on one side of the conductive shaft 30 and are in rotational contact with the outer circumferential surface of the conductive shaft 30 and in electrical contact therewith, and the wire 45 is further electrically connected with the conductive block, the conductive pin, etc. For the part of the conductive assembly 40 that needs to be fixedly installed, in the current collector 10, the conductive rotating shaft 30 is generally sleeved with a sleeve (i.e. the rotating connecting member 51), so that the part of the conductive assembly 40 that needs to be fixedly installed can be installed on the sleeve.

In summary, it can be understood that the current collector 10 provided by the present application is electrically contacted with the conductor 21 on the sliding contact member 20 through the conductive rotating shaft 30, and is also electrically contacted with the conductive rotating shaft 30 through the conductive element 40, and the conductive element is electrically connected with the to-be-used electrical device through the conducting wire 45, that is, the conducting wire 45 is electrically connected with the conductive rotating shaft 30 to transmit the electrical energy on the sliding contact member 20 to the to-be-used electrical device, and further does not need to be directly connected with the sliding contact member 20. Therefore, the situation that the movement of the sliding contact piece 20 is restrained when the cable is directly connected with the sliding contact piece 20 can be avoided, and the technical problem that the movement of the carbon brush (namely the sliding contact piece 20) is easily restrained by the cable in the conventional current collector 10 is effectively solved.

Optionally, in an embodiment, please refer to fig. 2, fig. 3 and fig. 6, the conductive rotating shaft 30 has a first conductive arc portion 31, the conductive body 21 has a second conductive arc portion 211, and the second conductive arc portion 211 surrounds the first conductive arc portion 31 and is rotatably connected to the first conductive arc portion 31. That is, in this embodiment, the electric contact is realized between the conductive rotating shaft 30 and the electric conductor 21 through the rotation contact of the arc surface and the arc surface, so that the electric conductor 21 can be ensured to be in electric contact with the conductive rotating shaft 30 no matter the electric conductor 21 rotates to any angle relative to the conductive rotating shaft 30, and the contact area is stable, thereby ensuring the stable conduction of the electric energy.

The sizes of the radius and the central angle corresponding to the first conductive arc portion 31 and the second conductive arc portion 211 are not limited, and only the mutual contact is ensured within the swing range of the conductor 21. As to the manner of forming the first conductive arc portion 31 and the second conductive arc portion 211, optionally, in an embodiment, as shown in fig. 3 to 5, the sliding contact 20 further includes an insulator 22, the insulator 22 is disposed on a side of the conductor 21 away from the current-carrying rail 110, and a first groove 221 is disposed on the insulator 22; the conductor 21 is provided with a second groove 212, the second groove 212 is located in the first groove 221, and the portion of the conductor 21 exposed in the first groove 221 forms the second conductive arc portion 211. Specifically, the first groove 221 and the second groove 212 are both U-shaped, and the first groove 221 is larger than the second groove 212, so that the side portion of the conductor 21 where the second groove 212 is formed is located in the first groove 221, and the side portion is used as the second conductive arc portion 211. It is understood that such a design facilitates the formation of the second conductive arc portion 211 without complicating the structure of the slider 20.

Optionally, in an embodiment, please refer to fig. 6 and 7, the conductive rotating shaft 30 further includes an arc-shaped conductive portion 32 and an insulating sleeve 33, the arc-shaped conductive portion 32 is rotatably installed in the first groove 221, and the insulating sleeve 33 is sleeved outside the arc-shaped conductive portion 32; the insulating sleeve 33 is provided with an arc-shaped opening 331, and a portion of the arc-shaped conductive part 32 corresponding to the arc-shaped opening 331 forms the first conductive arc part 31.

In this embodiment, the arc-shaped conductive portion 32 of the conductive rotating shaft 30 is a disk structure, the first groove 221 has two opposite side walls 223, each of the side walls is provided with a limit buckle 222, please refer to fig. 2, the two limit buckles 222 are respectively located at two sides of the arc-shaped conductive portion 32 in the radial direction and located at one side of the arc-shaped conductive portion 32 away from the sliding contact portion 20, so that the arc-shaped conductive portion 32 can stably rotate in the first groove 221 without separating under the limit of the two limit buckles 222, and the arc-shaped conductive portion 32 can be forcibly clamped into the first groove 221 during assembly. Of course, the arc-shaped conductive part 32 may also be rotatably installed in the first groove 221 by means of a pin, or alternatively, the insulating sleeve 33 is rotatably connected to the sliding contact part 20, and the arc-shaped conductive part 32 is installed in the insulating sleeve 33 and located in the first groove 221, so that the arc-shaped conductive part 32 is rotatably contacted with the conductive body 21 in the first groove 221.

As shown in fig. 6 and 7, an arc opening 331 is formed on the insulating sleeve 33, and the arc conductive portion 32 is at least partially exposed in the arc opening 331 to form the first conductive arc portion 31. Specifically, the insulating sleeve 33 may be sleeved outside the arc-shaped conductive portion 32 by injection molding, and when molding, a portion of the arc-shaped conductive portion 32 corresponding to the arc-shaped opening 331 may be recessed, flush, or protruded with respect to the arc-shaped opening 331, and a specific structure may be selected according to needs. It can be understood that the first arc-shaped conductive part 31 is formed by opening the arc-shaped opening 331 on the insulating sleeve 33, which not only facilitates the formation of the first arc-shaped conductive part 31, but also protects other parts of the arc-shaped conductive part 32, thereby avoiding accidental electric shock or short circuit with the adjacent current collector 10.

Optionally, in an embodiment, as shown in fig. 7, the insulating sleeve 33 includes two fixing lugs 334 arranged at intervals, a fixing cavity is formed between the two fixing lugs 334, and the arc-shaped opening 331 is communicated with the fixing cavity; the arc-shaped conductive part 32 is in a disc structure and is fixed in the fixing cavity, and part of the circumferential surface of the arc-shaped conductive part 32 is arranged corresponding to the arc-shaped opening 331. That is, with such a structure, the first conductive arc portion 31 is recessed with respect to the arc-shaped opening 331, so that the second conductive arc portion 211 needs to be at least partially embedded in the arc-shaped opening 331 and be in rotational contact with the first conductive arc portion 31. It can be understood that, when second conductive arc portion 211 imbeds arc opening 331, relative sliding of first conductive arc portion 31 and second conductive arc portion 211 on the axial direction can be restricted to two relative inner walls in arc opening 331, and then not only can guarantee first conductive arc portion 31 and the accurate contact of second conductive arc portion 211 when the equipment, can also keep the stable contact between first conductive arc portion 31 and the second conductive arc portion 211 at the in-process that uses.

In addition, in this embodiment, as shown in fig. 7, the insulating sleeve 33 further includes a first axial limiting portion 332, the first axial limiting portion 332 includes two limiting lugs 335 arranged at intervals, and at least part of the limiting lugs 335 protrude from the arc-shaped opening 331. Specifically, the two limiting lugs 335 are both plate-shaped structures and are disposed on two sides of the arc-shaped conductive portion 32 along the axial direction of the arc-shaped conductive portion 32, and after the conductive rotating shaft 30 is connected to the sliding contact piece 20, at least a part of the insulator 22 of the sliding contact piece 20 is clamped between the two limiting lugs, so as to limit the displacement of the arc-shaped conductive portion 32 in the axial direction.

In another embodiment, as shown in fig. 7, the insulating sleeve 33 further includes a second axial limiting portion 333, and the second axial limiting portion 333 is located on a side of the insulating sleeve 33 facing away from the sliding contact 20 and has a limiting surface 336 facing away from the sliding contact 20. Specifically, the second axial limiting portion 333 is a block-shaped structure and is disposed on a side of the arc-shaped conductive portion 32 away from the slider 20, the second axial limiting portion 333 is sleeved outside the conductive tail portion 34 (refer to the drawings), and the second axial limiting portion 333 can abut against an end portion of the rotating connector 51 through a limiting surface 336 thereof to limit a depth of the conductive tail portion 34 extending into the rotating connector 51.

Optionally, in an embodiment, please refer to fig. 2, 8 and 9, the current collector 10 further includes a connecting assembly 50, the connecting assembly 50 mainly includes a connecting rod 52 and two rotating connectors 51 respectively installed at two ends of the connecting rod 52, wherein one rotating connector 51 is used for connecting with the device to be powered, and the other rotating connector 51 is used for connecting with the conductive rotating shaft 30. Specifically, a rotating cavity 511 and a conducting cavity 512 are arranged in the rotating connecting piece 51, the rotating cavity 511 and the conducting cavity 512 both extend along the length direction of the rotating connecting piece 51, and a communication port 513 communicated with the conducting cavity 512 is arranged on the side wall of the rotating cavity 511; the conductive element 40 is installed in the conductive cavity 512, and at least partially extends into the rotating cavity 511 through the communication port 513; the conductive shaft 30 further has a conductive tail portion 34, the conductive tail portion 34 is a rod-shaped structure and is integrally formed with the arc-shaped conductive portion 32, and the conductive tail portion 34 is rotatably installed in the rotating cavity 511 and is in rotational contact with the conductive element 40.

It can be understood that the conductive element 40 is installed in the conductive cavity 512 of the rotary connector 51 and is in rotational contact with the conductive tail 34 of the conductive rotary shaft 30 through the communication opening 513, so that the rotation of the conductive rotary shaft 30 is not affected while the conductive rotary shaft 30 is in electrical contact with the conductive rotary shaft 30.

In order to limit the conductive tail 34 from separating from the rotation cavity 511 along the axial direction, in this embodiment, as shown in fig. 2, a limiting sleeve 35 is further sleeved at one end of the conductive tail 34 away from the arc-shaped conductive portion 32, the limiting sleeve 35 is made of an insulating material, a limiting ring groove 351 is formed in the outer peripheral surface of the limiting sleeve 35, as shown in fig. 9, a limiting ring protrusion 514 is arranged on the inner wall of the rotation cavity 511, and the limiting ring protrusion 514 is clamped in the limiting ring groove 351, so that the conductive tail 34 can be limited from separating from the rotation cavity 511, and the rotation of the conductive tail 34 is not affected.

Further, in order to facilitate the clamping connection between the limiting ring groove 351 and the limiting ring protrusion 514, as shown in fig. 7, the limiting sleeve 35 is provided with two elastic arms 352 at opposite intervals, the limiting ring groove 351 is formed in the periphery of each elastic arm 352, and the clamping connection convenience between the limiting ring groove 351 and the limiting ring protrusion 514 can be effectively improved through elastic deformation of the two elastic arms 352.

Of course, the position-limiting sleeve 35 may also be integrally formed with the conductive tail 34, that is, the end of the conductive tail 34 does not need to be covered with an insulating material, the position-limiting ring groove 351 may be directly disposed on the conductive tail 34, and the conductive tail 34 is directly engaged with the position-limiting ring protrusion 514.

Optionally, in an embodiment, as shown in fig. 2, the conductive assembly 40 includes a first conductive block 41, and the first conductive block 41 is slidably mounted in the conductive cavity 512 and contacts the conductive tail 34 through the communication opening 513; one side of the first conductive block 41, which faces away from the conductive tail 34, is further provided with an elastic element 42, one end of the elastic element 42 is abutted against the first conductive block 41, and the other end is abutted against the inner wall of the conductive cavity 512.

Specifically, in the present embodiment, the conductive cavity 512 extends parallel to the rotation cavity 511, the communication opening 513 is disposed near the bottom of the conductive cavity 512, and the first conductive block 41 is slidably mounted at the bottom of the conductive cavity 512, and extends into the rotation cavity 511 through the communication opening 513, so as to be in rotational contact with the conductive tail 34. It can be understood that if the first conductive block 41 protrudes into the rotation cavity 511 to a greater length, the friction between the first conductive block and the conductive tail 34 will be greater, and the rotation of the conductive tail 34 will be affected; if the length of the first conductive block 41 extending into the rotating cavity 511 is too small, the contact with the conductive tail 34 is not good, and the stable conduction of the electric energy is affected.

Therefore, in this embodiment, an elastic member 42 is further disposed on a side of the first conductive block 41 opposite to the conductive tail 34, one end of the elastic member 42 abuts against the first conductive block 41, and the other end of the elastic member abuts against an inner wall of the conductive cavity 512, so that the elastic force of the elastic member 42 is utilized to elastically contact the first conductive block 41 and the conductive tail 34, and the length of the first conductive block 41 extending into the rotation cavity 511 can be automatically adjusted, thereby not only avoiding affecting the rotation of the conductive tail 34, but also ensuring stable contact between the first conductive block 41 and the conductive tail 34.

In addition, in this embodiment, as shown in fig. 2, in order to ensure stable installation of the elastic element 42, the first conductive block 41 is further provided with a limiting groove, and one end of the elastic element 42 extends into the limiting groove and abuts against the first conductive block 41, so that the elastic element 42 can be limited by the limiting groove, and the elastic element 42 is prevented from automatically bouncing off. Of course, the limiting recess may be provided on the inner wall of the conductive cavity 512.

Optionally, in an embodiment, as shown in fig. 2, the conductive assembly 40 further includes a second conductive block 43, where the second conductive block 43 is fixed in the conductive cavity 512 and is provided with the connection terminal 44; the first conductive piece 41 is in sliding contact with the second conductive piece 43. Specifically, taking the extending direction of the conductive cavity 512 as the vertical direction as an example, the second conductive block 43 is fixed above the first conductive block 41 and is in sliding contact with the first conductive block 41, so that the electric energy on the first conductive block 41 can be conducted to the terminal 44. It can be understood that, by fixedly mounting the second conductive block 43 to realize the electric energy conduction between the first conductive block 41 and the connection terminal 44, the connection terminal 44 can be prevented from sliding along with the first conductive block 41, so as to ensure the stable positioning of the connection terminal 44 and prevent the pulling force of the cable from being transmitted to the first conductive block 41 through the connection terminal 44.

The connection terminal 44 may be formed by a structure on the second conductive block 43, or may be formed by a conductive structure mounted on the second conductive block 43, and the specific forming method is not limited. For example, in the present embodiment, the connection terminal 44 is formed by a screw screwed to the second conductive block 43. And the terminal 44 may be electrically connected to the cable by soldering, clamping, hinging, or the like.

Specifically, in the present embodiment, the connection terminal 44 is protruded at the opening of the conductive cavity 512, and the protection cover 60 is installed on the rotary connection member 51 and covers the connection terminal 44 to prevent an electric shock or a short circuit from occurring with the connection terminal 44 of the adjacent current collector 10.

The embodiment of the present application further provides a trolley line system 100, where the trolley line system 100 includes an electrified guide rail 110, a cable, and a current collector 10, and the specific structure of the current collector 10 refers to the above embodiments, and since the trolley line system 100 adopts all technical solutions of all the above embodiments, at least all beneficial effects brought by the technical solutions of the above embodiments are achieved, and details are not repeated here.
