The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
A current collector 100 and a power supply system of a vehicle according to an embodiment of the present invention are described below with reference to fig. 1 to 11.
As shown in fig. 1 and 2, according to the current collector 100 of the embodiment of the present invention, the current collector 100 includes: the base plate 10, the guide post 20, the first elastic member 30, the support frame assembly 40, the current receiving plate 50 and the driving assembly 60. It should be noted that the current collector 100 may cooperate with a conductive plate to charge the vehicle.
In particular, the floor 10 is adapted to be connected to a vehicle, i.e. the current collector 100 may be fixed to the vehicle by the floor 10. As shown in fig. 1 and 5, the guide post 20 is movably disposed on the base plate 10, and a first end of the guide post 20 extending out of the base plate 10 is provided with a limit boss 210. For example, the guide post 20 may move relative to the base plate 10 along its extending direction, and the limit boss 210 may limit the moving range of the guide post 20. As shown in fig. 5, two ends of the first elastic element 30 respectively abut against the limiting boss 210 and the bottom plate 10. Thereby, when the guide post 20 moves relative to the base plate 10, the first elastic member 30 can be driven to be elastically deformed. When the first elastic member 30 is in a state of different elastic restoring force, different pre-stresses can exist between the guide post 20 and the base plate 10.
As shown in fig. 1 and 5, the carriage assembly 40 is connected to the second end of the guide post 20 to move synchronously with the guide post 20. That is, as the guide post 20 moves relative to the base plate 10, the carriage assembly 40 also moves with the guide post 20. The current receiving plate 50 is connected to the supporting frame assembly 40, and the supporting frame assembly 40 moves to drive the current receiving plate 50 to move synchronously. Therefore, the current-receiving plate 50 can be driven by the support frame assembly 40 to move to adjust the distance between the current-receiving plate 50 and the conductive plate, so that the static contact force between the current-receiving plate 50 and the conductive plate can be adjusted.
The driving assembly 60 is connected with the carriage assembly 40 to drive the carriage assembly 40 to reciprocate along the extending direction of the guide post 20. Therefore, the driving assembly 60 can drive the support frame assembly 40 to drive the current-receiving plate 50 to move, so that the current-receiving plate 50 can be automatically controlled and adjusted.
It should be noted that, as shown in fig. 1 and 5, the driving assembly 60 can drive the carriage assembly 40 to move along the extending direction of the guide post 20 (up and down direction as shown in fig. 1 and 5). For example, when the driving assembly 60 drives the support frame assembly 40 to move downward, the support frame assembly 40 can drive the current-receiving plate 50 to move toward the conductive plate, so that the distance between the current-receiving plate 50 and the conductive plate can be reduced. Meanwhile, the support frame assembly 40 drives the guide post 20 to move synchronously, and the guide post 20 extrudes the first elastic member 30 to generate elastic deformation, so that the acting force between the support frame assembly 40 and the bottom plate 10 is increased. Thereby, the static contact force between the current-receiving plate 50 and the conductive plate can be increased, thereby improving the firmness and reliability of the fit between the current-receiving plate 50 and the conductive plate.
When it is desired to reduce the static contact force between the current collector 50 and the conductive plate, or to separate the current collector 100 from the conductive plate, the driving assembly 60 moves upward. Under the elastic restoring force of the first elastic member 30, the first elastic member 30 drives the guide pillar 20 to move in a direction away from the conductive plate, and the guide pillar 20 drives the support frame assembly 40 and the current-receiving plate 50 to move together in a direction away from the conductive plate, so that the static contact force between the current-receiving plate 50 and the conductive plate can be reduced, or the current-receiving plate 50 is separated from the conductive plate. Therefore, the adjustment of the contact force between the current receiving plate 50 and the conductive plate can be more convenient and reliable.
According to the current collector 100 of the embodiment of the invention, through the cooperation between the driving assembly 60 and the first elastic member 30, the supporting frame assembly 40 can be driven to drive the current-receiving plate 50 to move toward or away from the conductive plate, so that the static contact force between the current-receiving plate 50 and the conductive plate can be adjusted, and the cooperation between the current-receiving plate 50 and the conductive plate is firmer and more reliable. Thus, the stability and reliability of vehicle charging are improved. Moreover, under the cooperation of the driving assembly 60 and the first elastic element 30, the supporting frame assembly 40 can be conveniently driven to drive the current-receiving plate 50 to be separated from the conductive plate, so that the current collector 100 can be conveniently and efficiently separated from the conductive plate. In addition, the structure of the current collector 100 is compact and reasonable, the movement space is small, and the occupied space of the current collector 100 is reduced.
According to some embodiments of the present invention, as shown in fig. 2-5, the support frame assembly 40 may include: a support bracket 410 and a connecting rod 420. The support bracket 410 is connected to the second end of the guide post 20, and the driving assembly 60 is connected to the support bracket 410 to drive the support bracket 410 to move. Therefore, when the driving assembly 60 drives the supporting frame 410 to move, the supporting frame 410 can drive the guide post 20 to move synchronously. The connecting rods 420 are disposed on the supporting frame 410, and the current-receiving plate 50 is disposed on the connecting rods 420. Therefore, the current receiving plate 50 can be conveniently fixed to the support frame assembly 40 through the connecting rod 420, which facilitates the fixed assembly of the current receiving plate 50.
In some embodiments of the present invention, as shown in fig. 5, the connecting rod 420 is movably disposed on the supporting frame 410, and the connecting rod 420 is configured to move synchronously with the supporting frame 410 when the driving assembly 60 drives the supporting frame 410 to move. It should be noted that, as shown in fig. 4 and 5, when the driving assembly 60 drives the supporting frame 410 to move, the connecting rod 420 and the driving assembly 60 move synchronously, so as to drive the current receiving plate 50 to move synchronously.
As shown in fig. 5, the connection rod 420 may be movable in its extending direction with respect to the support bracket 410. For example, when the current receiving plate 50 is impacted, the connecting rod 420 can move the current receiving plate 50 to buffer the impact of the current receiving plate 50.
As shown in fig. 2 and 3, the supporting frame assembly 40 may further include a second elastic member 430, and both ends of the second elastic member 430 respectively abut against the connecting rod 420 and the supporting frame 410. Therefore, when the current-receiving plate 50 is impacted, the connecting rod 420 can press the second elastic member 430 to generate elastic deformation, and the second elastic member 430 can convert the impact force on the current-receiving plate 50 into elastic potential energy to buffer and absorb the impact on the current-receiving plate 50.
According to some embodiments of the present invention, as shown in fig. 5 and 7, the connection rod 420 may include: the first rod 421 is disposed on the supporting frame 410, the second elastic member 430 is supported on the first rod 421, the second rod 422 is connected to an end of the first rod 421 close to the flow receiving plate 50, and the flow receiving plate 50 is disposed on the second rod 422. As shown in fig. 5, the upper end of the second rod 422 is connected to the lower end of the first rod 421, and the current-receiving plate 50 is fixed to the lower end of the second rod 422. Therefore, the assembly connection of the connecting rod 420 is facilitated, so that the assembly efficiency of the current collector 100 can be improved, and the production cost of the current collector 100 can be reduced. Furthermore, the first rod 421, the second rod 422 and the flow receiving plate 50 can move synchronously, so that the position of the flow receiving plate 50 can be adjusted conveniently.
In some embodiments of the invention, at least a portion of the tie bar 420 is an insulator. That is, the tie bar 420 may be partially provided as an insulating portion, or may be entirely provided as an insulating portion. For example, the first rod 421 may be an insulating member, the second rod 422 may be an insulating member, or both the first rod 421 and the second rod 422 may be insulating members, and at least a portion of the connecting rod 420 may be an insulating portion, so that a potential safety hazard caused by the current on the flow plate 50 being transmitted to the vehicle body through the connecting rod 420 may be avoided, and the safety of the current collector 100 may be improved.
According to some embodiments of the present invention, as shown in fig. 7 and 9, the outer circumferential wall of the insulation part is provided with a plurality of annular insulation grooves 4221, and the plurality of insulation grooves 4221 are spaced apart along the length direction of the tie bar 420. Therefore, the creepage distance of the insulating part can be increased, the insulating effect of the insulating part is enhanced, and the safety performance of the current collector 100 is further improved.
In some embodiments of the present invention, as shown in fig. 6-8, one of the connecting rod 420 and the supporting bracket 410 is provided with a rotation stop protrusion 4211, and the other is provided with a rotation stop groove 4122 adapted to the rotation stop protrusion 4211. That is, the rotation stopping protrusions 4211 may be provided on the connecting rod 420, and the rotation stopping grooves 4122 may be provided on the support bracket 410; alternatively, the connecting rod 420 may be provided with a rotation stopping groove 4122, and the support bracket 410 may be provided with a rotation stopping protrusion 4211. The rotation stop protrusions 4211 are engaged with the rotation stop grooves 4122 to prevent the relative rotation between the connecting rod 420 and the supporting bracket 410. Therefore, the current receiving plate 50 and the current conducting plate can be matched more stably and reliably, and the stability and the reliability of vehicle charging are improved.
According to some embodiments of the present invention, as shown in fig. 5 and 6, the support frame 410 may include: the connecting rod 420 comprises a first component 411, a second component 412 and a connecting arm 413, wherein the first component 411 is provided with a first through hole 4110 which penetrates through the first component 411, the second component 412 and the first component 411 are arranged at intervals along the extending direction of the connecting rod 420, the second component 412 is provided with a second through hole 4121 opposite to the first through hole 4110, the first end of the connecting rod 420 sequentially penetrates through the second through hole 4121 and the first through hole 4110 and then is connected with a fastening piece 440, and the fastening piece 440 abuts against the end face, far away from the second component 412, of the first component 411. For example, the fastener 440 may be a bolt that is threadedly engaged with the first end of the connecting rod 420. One end of the connecting arm 413 is connected to the first member 411, and the other end of the connecting arm 413 is connected to the second member 412.
It should be noted that, as shown in fig. 5 and 6, the upper end of the connecting rod 420 passes through the second through hole 4121 and the first through hole 4110 in sequence, and the connecting rod 420 can move up and down in the first through hole 4110 and the second through hole 4121 to absorb the impact between the current receiving plate 50 and the conductive plate. The upper end of the connecting rod 420 abuts against the upper end surface of the first member 411 to limit the moving range of the connecting rod 420, and the connecting rod 420 is prevented from being separated from the supporting bracket 410.
In some embodiments of the present invention, the connection arm 413 is provided in a plurality at intervals, and the plurality of connection arms 413 are provided at intervals along the circumferential direction of the second through hole 4121. As shown in fig. 6, the connecting arms 413 may be provided at intervals of two in the circumferential direction of the second through hole 4121, and the two connecting arms 413 may be symmetrically provided. Therefore, the stability and firmness of the structure of the support frame 410 can be improved.
According to some embodiments of the present invention, the guide posts 20 and the first elastic members 30 may be a plurality of each, and the plurality of guide posts 20 and the plurality of first elastic members 30 are disposed in a one-to-one correspondence. As shown in fig. 5, the guide post 20 and the first elastic member 30 may be two symmetrically disposed. Therefore, the running stability and reliability of the support frame 410 can be improved.

As shown in fig. 4, the upper end of the cylinder may be fixedly connected to the bottom plate 10, and the lower end of the cylinder abuts against the supporting frame 410. When the cylinder is extended, the support frame 410 may be driven to move downward to improve the stability of the contact between the current-receiving plate 50 and the conductive plate. When the cylinder is shortened, under the elastic restoring force of the first elastic member 30, the guide post 20 can drive the support frame assembly 40 to move upward, so as to drive the current-receiving plate 50 to move away from the conductive plate, so as to reduce the contact stress between the current-receiving plate 50 and the conductive plate or achieve the boot removal of the current-receiving plate 50.

As shown in fig. 7-9, the connecting rod 420 includes a first rod 421 and a second rod 422, the first rod 421 sequentially passes through the second through hole 4121 and the first through hole 4110 from bottom to top, and the upper end of the first rod 421 extends out of the first through hole 4110 and is assembled with a bolt that abuts against the upper end surface of the first member 411. The first rod 421 can move up and down in the first through hole 4110 and the second through hole 4121, the outer peripheral wall of the first rod 421 is provided with a rotation stop protrusion 4211, and the inner peripheral wall of the second through hole 4121 is provided with a rotation stop groove 4122 to prevent the first rod 421 from rotating relative to the supporting frame 410.
The first rod 421 is sleeved with a second elastic member 430, the second elastic member 430 is a spring, an upper end of the second elastic member 430 is abutted against the first member 411, and a lower end of the second elastic member 430 is abutted against the first rod 421. As shown in fig. 8, the pipe diameter of the upper section of the first rod 421 is smaller than the pipe diameter of the lower section. The lower end of the second elastic member 430 is stopped against the transition step surface of the thin pipe section and the thick pipe section of the first rod 421.
As shown in fig. 7 and 9, the second rod 422 is an insulating rod, and the upper end of the second rod 422 is sleeved inside the lower end of the first rod 421. A plurality of annular insulating grooves 4221 are formed in the outer peripheral wall of the second rod body 422, and the insulating grooves 4221 are arranged at intervals in the vertical direction to increase the creepage distance of the second rod body 422. A fixing plate 4222 extending in the front-rear direction is provided at the lower end of the second rod 422. The current receiving plate 50 is fixed to the fixing plate 4222 by bolts and nuts, and the current receiving plate 50 is a carbon slide plate.
As shown in fig. 4 and 6, the driving unit 60 is a cylinder, the upper end of the cylinder is fixed to the base plate 10 by bolts, and the lower end of the cylinder abuts against the flange 4123 of the second member 412.
It should be noted that when the cylinder extends downward, the cylinder pushes the support frame 410 to move downward. In the process of moving the support frame 410 downward, the connecting rod 420 and the current-receiving plate 50 are driven to synchronously move downward. Meanwhile, the supporting frame 410 drives the guide pillar 20 to move downward synchronously, and the guide pillar 20 presses the first elastic member 30 and elastically deforms the first elastic member 30. Thereby, the force between the support frame assembly 40 and the base plate 10 is increased, and the distance between the current-receiving plate 50 and the conductive plate is reduced, thereby improving the static contact force between the current-receiving plate 50 and the conductive plate.
When the cylinder contracts upwards, the first elastic member 30 drives the guide post 20 to move upwards and simultaneously drives the support frame assembly 40 and the current-receiving plate 50 to move upwards together under the elastic restoring force of the first elastic member 30. Accordingly, the static contact force between the current-receiving plate 50 and the conductive plate can be reduced, and the shoe removal of the current collector 100 can be realized, which is simple in structure and convenient in operation.
Also, when the current receiving plate 50 receives an impact, the current receiving plate 50 moves in the up-down direction by pressing the second elastic member 430 with the connection rod 420, so that the impact received by the current receiving plate 50 can be absorbed with cushioning.
Therefore, through the cooperation between the driving assembly 60 and the first elastic element 30, the supporting frame assembly 40 can be driven to drive the current-receiving plate 50 to move toward the direction close to or away from the conductive plate, so that the static contact force between the current-receiving plate 50 and the conductive plate can be adjusted, and the cooperation between the current-receiving plate 50 and the conductive plate is more firm and reliable. Thus, the stability and reliability of vehicle charging are improved. Moreover, under the cooperation of the driving assembly 60 and the first elastic element 30, the supporting frame assembly 40 can be conveniently driven to drive the current-receiving plate 50 to be separated from the conductive plate, so that the current collector 100 can be conveniently and efficiently separated from the conductive plate. In addition, the structure of the current collector 100 is compact and reasonable, the movement space is small, and the occupied space of the current collector 100 is reduced.
