The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
Referring to fig. 1 to 11, a joint device 100 according to an embodiment of the present invention is described below, wherein the joint device 100 may serve to connect two conductive rails, and a carbon sliding plate 200 of a current collector on a vehicle may transition from one conductive rail to the other conductive rail through the joint device 100, so as to achieve the purpose of power taking.
As shown in fig. 1 to 3, a joint device 100 according to an embodiment of the present invention includes: the contact rail comprises two contact rails 1, a connecting assembly 2 and a current connecting part 3, wherein the two contact rails 1 are arranged along the length direction of the contact rails 1, namely, one contact rail 1 is positioned at one end of the other contact rail 1 in the length direction of the contact rail 1. The connecting assemblies 2 are respectively connected with two contact rails 1, and at least one contact rail 1 is a moving rail 1b which moves relative to the connecting assemblies 2. Specifically, the two contact rails 1 are connected by the connecting assembly 2, and may be a fixed rail 1a in which one contact rail 1 is a moving rail 1b and the other contact rail 1 is fixed relative to the connecting assembly 2; or it may be that both contact rails 1 are moving rails 1b. In some embodiments of the present invention, the connection assembly 2 is configured to define five degrees of freedom of the moving rail 1b such that the moving rail 1b can move only in its length direction with respect to the fixed rail 1a, thereby improving reliability of the joint device 100. According to some specific examples of the present invention, one contact rail 1 is a moving rail 1b, the other contact rail 1 is a fixed rail 1a, a long waist hole with the length of 130-160 mm is machined on the moving rail 1b, and a matching piece such as a bolt passing through the long waist hole is fixed with the connecting assembly 2, so that the relative sliding distance of the moving rail 1b relative to the fixed rail 1a is not less than 120mm, and the joint device 100 can effectively play a transitional role.
The current connection part 3 includes a plurality of current connectors 30, and each current connector 30 is electrically connected with the two contact rails 1 to conduct current. I.e. each current connector 30 is used for conducting a current, the current flowing from one of the contact rails 1 can flow through a plurality of current connectors 30 onto the other contact rail 1, i.e. the current can be transmitted through a plurality of current connectors 30 for conducting the two contact rails 1.
It will be appreciated that, since the plurality of current connectors 30 are provided to perform current transmission, the plurality of current connectors 30 can split current compared with the case where only one current connector is used to perform current transmission in the related art, and the total cross-sectional area of the plurality of current connectors 30 of the present invention can be smaller than that of the single current connector of the related art, so that the height of each current connector 30 of the present invention can be smaller than that of the current connector of the related art on the premise of the same current carrying capacity, and thus the current connection part 3 according to the present invention is more suitable for the working conditions with higher requirements on the installation limit and the electrical insulation gap.
Further, since the plurality of current connectors 30 are used for current transmission as described above, the total sectional area of the current connection part 3 can be reduced as compared with the related art, and the height of each current connector 30 can be made smaller, so that the overall rigidity of the current connection part 3 can be reduced as compared with the related art, each current connector 30 is easier to deform, and the resistance generated by the movement of the current connection part 3 to the movement of the movement rail 1b can be reduced when the movement rail 1b moves relative to the connection assembly 2, thereby achieving the purpose of reducing the initial slip force of the joint device 100.
In some embodiments of the present invention, as shown in fig. 2 and 3, the number of the current connectors 30 is four, so that the current passing through each current connector 30 is only one fourth of that of the related art single current connector, thereby greatly reducing the sectional area of the current connector 30 of the embodiment of the present invention.
Specifically, each of the current connectors 30 may be wound with a plurality of layers of T2 copper foil, wherein each layer of T2 copper foil has a thickness of 0.1mm or 0.08mm, and each of the current connectors 30 has a thickness of not more than 6mm, thereby reducing the rigidity of the current connector 30 and reducing the influence of the current connector 30 on the movement of the moving rail 1b.
According to the joint device 100 of the embodiment of the present invention, the two contact rails 1 are connected through the connection assembly 2, and compared with the related art, the joint device 100 eliminates the middle rail, which is beneficial to smooth current receiving of the vehicle, and simultaneously, compared with the related art, the total cross-sectional area and the height of the current connection part 3 are reduced by adopting a plurality of current connectors 30 for current transmission, so that the cost can be reduced, the application range of the joint device 100 is wide, the rigidity of the current connection part 3 can be reduced, and the initial sliding force of the joint device 100 is reduced.
As shown in fig. 1-3 and 9, in some embodiments of the invention, the end of one contact rail 1 facing the other is provided with an insertion groove 10, and the end of the other contact rail 1 is provided with an insertion portion 11, the insertion portion 11 extending into the insertion groove 10. Thus, by providing the protruding portion 11 to be engaged with the protruding groove 10 so that the end portions of the two contact rails 1 are formed in complementary structures, it is possible to ensure that at least half of the area of the carbon slide 200 is in contact with the joint device 100 when passing through the gap between the two contact rails 1, so that the carbon slide 200 can smoothly pass through the joint device 100, and it is ensured that the current collector can continuously and smoothly receive current when passing through the joint device 100.
Specifically, as shown in fig. 1 to 3 and 9, the protruding portion 11 is formed as a "V" shaped protrusion, and the protruding groove 10 is formed as a "V" shaped groove, wherein the protruding portion 11 and the protruding groove 10 are symmetrically disposed with respect to the central axis of the contact rail 1, respectively, and the angle α of the protruding groove 10 may be set to be not more than 90 °, so that it may be further ensured that at least half of the area of the carbon sliding plate 200 is in contact with the joint device 100 when passing through the gap between the two contact rails 1, so that the carbon sliding plate 200 may smoothly pass through the joint device 100, and it is ensured that the current collector may continuously and smoothly flow when passing through the joint device 100.
It will of course be appreciated that the structure of the ends of the two contact rails 1 towards each other is not limited thereto, as long as it is ensured that the carbon sled 200 can pass smoothly through the joint device 100, for example as shown in fig. 10, each contact rail 1 is provided with a bevel cut, i.e. the ends of the two contact rails 1 towards each other are formed as mutually parallel bevel structures. As shown in fig. 11, for example, a Z-shaped notch is provided on each contact rail 1, that is, the end of each contact rail 1 is provided with an extending portion 11 and an extending groove 10, the ends of two contact rails 1 are in plug-in fit, the extending groove 10 of one contact rail 1 is provided with the extending portion 11 of the other contact rail 1, and the extending portion 11 of one contact rail 1 is inserted into the extending groove 10 of the other contact rail 1.
In a further embodiment of the invention, as shown in fig. 2-5, the connector device 100 further comprises a conductive strip 4, the conductive strip 4 being fixed to the moving rail 1b, each current connector 30 being fixed to the conductive strip 4. It will be appreciated that the conductive strip 4 serves as a conductor and, by providing the conductive strip 4, it also facilitates the fixing of the current connector 30 on the basis of ensuring the conductive effect. Alternatively, the conductive strip 4 may be a copper-clad aluminum conductive strip 4, so that the conductive effect of the conductive strip 4 is good and the cost is low. Further, the conductive strip 4 may be welded and fixed to the center of the rail bottom of the moving rail 1b.
Further, as shown in fig. 3, the conductive strip 4 extends along the length direction of the moving rail 1b, and the current connectors 30 are distributed on both sides in the thickness direction of the conductive strip 4. So that space can be reasonably utilized and the installation of the current connector 30 is facilitated. Specifically, as shown in fig. 3 and 5, the number of the current connectors 30 is four, two current connectors 30 are distributed on each side of the conductive strip 4, the current connectors 30 on two sides of the conductive strip 4 are opposite to each other, and the two opposite current connectors 30 can be fixed on the conductive strip 4 through one fixing connecting piece 16, so that the installation efficiency can be improved, and the cost can be reduced.
As shown in fig. 5, in some specific examples of the present invention, the connector device 100 further includes a first clamping plate 14 and a second clamping plate 15, where the first clamping plate 14 and the second clamping plate 15 are distributed on two sides of the conductive strip 4, and the fixing connection piece 16, such as a bolt, sequentially passes through the first clamping plate 14, one of the current connectors 30, the conductive strip 4, and the other current connector 30, and then is fixed on the second clamping plate 15, so as to avoid damage to the current connector 30 when the current connector 30 is installed, and prolong the service life of the current connector 30.
According to some embodiments of the present invention, as shown in fig. 1 to 7, the connection assembly 2 includes two limiting conductive plates 20, the two limiting conductive plates 20 are distributed on both sides of the contact rail 1, and both ends of each limiting conductive plate 20 are respectively matched with the two contact rails 1 to move the moving rail 1b along the length direction thereof. Specifically, the two contact rails 1 are clamped between the two limit conductive plates 20, and each contact rail 1 is respectively engaged with the limit conductive plates 20 on both sides, so that the moving rail 1b can move along the length direction thereof. Thereby making the structure of the connection assembly 2 simple. In some specific examples of the present invention, as shown in fig. 5 and 6, one end of each of the stopper plates 20 is fixed to the fixed rail 1a (for example, two stopper plates 20 are fixed to the fixed rail 1a by bolts), and the other end of each of the stopper plates 20 is provided with a fitting member, for example, a bolt, which passes through an elongated hole (for example, a waist-shaped hole) in the moving rail 1b so that the moving rail 1b can extend in the length direction thereof.
As shown in fig. 5, in some embodiments of the invention, a portion of each current connector 30 is secured to the spacing conductive plate 20. Thereby facilitating assembly of the current connector 30. In some embodiments of the present invention, a portion of each current connector 30 is secured to the spacing conductive plate 20 and another portion is secured to the conductive strip 4, at which time the current may pass through "one of the contact rails"path transmission. It should be noted that, although the two limiting conductive plates 20 may also function as conductors, most of the current is transmitted through the current connection member 3.
Further, as shown in fig. 5, a composite board 5 is disposed between the current connector 30 and the limiting conductive plate 20, the composite board 5 has a first contact surface and a second contact surface with different materials, the first contact surface contacts the current connector 30 and the first contact surface is made of the same material as the current connector 30, the second contact surface contacts the limiting conductive plate 20 and the second contact surface is made of the same material as the limiting conductive plate 20. Thus, by arranging the composite board 5, electrochemical corrosion caused by direct contact between the current connector 30 and the limiting conductive board 20 can be avoided, thereby ensuring the conductive effect of the current connector 30 and prolonging the service life of the connector device 100. In a specific example of the present invention, the composite board 5 is a copper-aluminum composite board 5, the first contact surface is a copper board surface, and the second contact surface is an aluminum board surface, that is, the copper-aluminum composite board 5 is disposed between the current connector 30 and the limiting conductive board 20, the copper board surface of the copper-aluminum composite board 5 contacts the current connector 30, and the aluminum board surface of the copper-aluminum composite board 5 contacts the limiting conductive board 20.

As shown in fig. 7, according to some embodiments of the present invention, a surface of each of the limiting conductive plates 20 facing the moving rail 1b is provided with a notch 201. Thereby, the contact area between the limiting conductive plate 20 and the moving rail 1b can be reduced, thereby reducing the friction force between the limiting conductive plate 20 and the moving rail 1b and reducing the abrasion.
In some further embodiments of the invention, as shown in fig. 2 and 5, a first gasket 6 is provided between the connection assembly 2 and the moving rail 1b. Thereby, the problems of excessive friction force and mutual abrasion caused by direct contact of the connecting component 2 and the movable rail 1b can be avoided, the friction force during sliding of the movable rail 1b is reduced, the abrasion of the connecting component 2 is avoided, and the service life of the joint device 100 is prolonged. In particular, the first liner 6 may be a self-lubricating liner, made of a plastic material having self-lubricating properties and being resistant to wear.
Further, as shown in fig. 2 and 6, since the first gasket 6 is provided between the connection assembly 2 and the moving rail 1b, resulting in a gap between the connection assembly 2 and the fixed rail 1a, in order to eliminate the gap, the second gasket 7 is provided between the fixed rail 1a and the connection assembly 2, so that the gap between the connection assembly 2 and the fixed rail 1a, and between the connection assembly 2 and the moving rail 1b can be adjusted, so that the gap between the connection assembly 2 and the fixed rail 1a and the moving rail 1b is approximately the same, thereby ensuring that the moving rail 1b can smoothly slide on the connection assembly 2 without jamming. Alternatively, the number of the second pads 7 may be plural, the second pads 7 may be composed of an aluminum sheet (e.g., an aluminum sheet having a thickness of 0.5 mm), thereby facilitating adjustment of a gap between the connection assembly 2 and the fixed rail 1a, and the structure of the second pads 7 is simple.
As shown in fig. 2 and 7, in some embodiments of the present invention, the connection assembly 2 further includes a support block 21, the support block 21 being positioned between the two spacing conductive plates 20 to define a spacing between the two spacing conductive plates 20. So that it is possible to avoid the reduction of the distance between the two limit conductive plates 20 after the connection assembly 2 is fixed to the contact rail 1 (for example, it is possible to prevent the reduction of the distance between the two limit conductive plates 20 after the bolt is tightened), thereby avoiding the increase of the initial sliding force and the jamming of the joint device 100 due to the reduction of the gap between the limit conductive plates 20 and the moving rail 1b.
Specifically, as shown in fig. 7, each of the limiting conductive plates 20 is provided with a mounting groove 202, both end portions of the supporting blocks 21 respectively extend into the mounting grooves 202 on the corresponding sides, specifically, the end portions of the two supporting blocks 21 are provided with a protruding portion 210, the outer peripheral wall of the protruding portion 210 is located on the inner side of the outer peripheral wall of the portion of the supporting block 21 connected thereto, that is, the protruding portion 210 extends into the corresponding mounting groove 202, and the rest of the supporting block 21 is stopped against the two limiting conductive plates 20 to support the two limiting conductive plates 20. So that the mounting manner of the supporting block 21 is simple and reliable.
As shown in fig. 2, 7 and 8, in some embodiments of the present invention, the connection assembly 2 is provided with a moving groove 22, and the moving groove 22 extends along the length direction of the contact rail 1. The joint device 100 further comprises a mobile element 8, a part of the mobile element 8 being movably located in the mobile slot 22, the mobile element 8 being adapted to be fixed to the external support 300. Therefore, when the joint device 100 expands or contracts, the joint device 100 can move along the length direction relative to the moving piece 8, so that the reduction of the adjustment amount of the joint device 100 caused by completely fixing the joint device 100 on the external support piece 300 is avoided, and meanwhile, when the joint device 100 is installed on a curve section route, the external support piece 300 can bear the elastic deformation force of the curve section conductive rail due to the movement of the moving piece 8, the contact force between the connecting assembly 2 and the moving rail 1b is reduced, and the clamping stagnation of the joint device 100 is avoided.
Specifically, each of the limiting conductive plates 20 is provided with a moving groove 22, and both ends of the moving member 8 are respectively movably inserted into the moving grooves 22 on the corresponding sides, so that the assembling reliability of the moving member 8 can be improved. Further, the external support 300 is an insulating support, and the moving member 8 may be fixed to the insulating support by a plurality of screws.
Further, as shown in fig. 2 and 8, the moving member 8 is provided with a rolling member 9 capable of rolling, and the rolling member 9 is in rolling engagement with the inner side wall of the moving groove 22. So that wear between the moving member 8 and the moving groove 22 can be reduced, and at the same time, jamming of the joint device 100 can be further avoided. In the specific example of the present invention, the rolling member 9 is a ball, and a plurality of balls are provided on opposite sides of the moving member 8, each ball being in rolling engagement with the inner side wall of the moving groove 22.
