Description

Technical Field

[0001] This utility model relates to the field of current collector technology, specifically to a current collector for trolleybuses. Background Technology

[0002] As an electrically powered public transportation vehicle, trolleybuses require a stable power supply from the overhead contact network via current collectors to drive the vehicle's electric motors, thus enabling the vehicle to move. With increasingly stringent environmental regulations, trolleybuses, with their "zero-emission" advantage, can meet the needs of air pollution control and align with the development trend of new energy vehicles, gaining increasing attention in the urban transportation sector. To improve the operational efficiency and service quality of trolleybuses, the technological improvement of current collectors has become an important research direction. In existing technologies, the current collector pole needs to be manually pulled back to its original position after being lowered, which is time-consuming and wastes manpower. Therefore, there is an urgent need for a device that can effectively solve the above problems, allowing for rapid and automatic return of the current collector pole after it has been lowered. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a current collector for trolleybuses, which solves the technical problem in related technologies that the current collector pole cannot be quickly and automatically returned to its original position after being lowered.

[0006] A swing arm is rotatably mounted on the base at one end. The axis of rotation of the swing arm is perpendicular to the top surface of the trolleybus, and the swing arm extends toward the front of the trolleybus.

[0007] A current collector rod is rotatably mounted on the swing arm at one end, with the rotation axis of the current collector rod perpendicular to the rotation axis of the swing arm. The other end of the current collector rod extends toward the rear of the trolleybus. The current collector rod is able to rotate with the swing arm.

[0008] A drive unit is mounted on the base and located below the rotation center of the swing arm;

[0009] The traction rope has its two ends respectively mounted on the swing arm and the drive component, and the drive component can drive the swing arm to rotate via the traction rope.

[0010] For example, at least one embodiment of this utility model provides a current collector for a trolleybus, comprising:

[0011] A connecting rod is installed on the current collector rod;

[0012] A telescopic component, one end of which is hinged to the extension end of the swing arm, and the other end of which is hinged to the connecting rod, the telescopic component being located above the swing arm and the current collector rod;

[0013] An elastic element, one end of which is rotatably mounted on the swing arm, and the other end of which is rotatably mounted on the current collector rod;

[0014] The elastic element can pull the current collector rod up, and the telescopic element can provide a force to assist the current collector rod in rising or falling.

[0015] For example, at least one embodiment of this utility model provides a current collector for a trolleybus, comprising:

[0016] A limiting component is installed on the top of the trolleybus. The limiting component is located in the extension direction of the current collector pole. The limiting component has two limiting hooks, which are located on the top of the trolleybus. The limiting hooks can hook and limit the movement of the current collector pole after it has been lowered.

[0017] For example, at least one embodiment of this utility model provides a current collector for a trolleybus, wherein the limiting component includes:

[0018] A bracket is installed on the top of the trolleybus. The bracket has a rotating component, and a limiting hook is installed on the rotating component. After the limiting hook rotates, it can limit the movement of the lowered collector rod.

[0019] For example, in at least one embodiment of this utility model, a current collector for a trolleybus is provided, wherein the limiting component further includes:

[0020] A guide member is disposed on the bracket and located between the two limiting hooks. The guide member can limit the direction of movement of the current collector rod.

[0021] For example, at least one embodiment of this utility model provides a current collector for a trolleybus, comprising:

[0022] A rope winder is installed at the rear of the trolleybus. The rope winder has a pull rope inside, which is connected to the current collector pole. The rope winder can pull down or release the current collector pole by pulling the pull rope.

[0023] For example, at least one embodiment of this utility model provides a current collector for a trolleybus, comprising:

[0024] A current collector head is mounted on the current collector rod, and the current collector head has a rotating shaft;

[0029] The beneficial effects of the embodiments of this utility model are as follows:

[0030] In this invention, after the trolleybus stops running, the current collector pole deviates from the direction of the vehicle body due to external forces during the trolleybus's operation. A device is needed to rotate the current collector pole to be parallel to the trolleybus body. A drive mechanism pulls the traction rope, causing the swing arm to rotate. Furthermore, the swing arm rotates the current collector pole. When the traction rope is pulled parallel to the trolleybus body, the current collector pole is simultaneously parallel to the vehicle body, meaning it has returned to its correct position. Lowering the current collector pole to a position parallel to the roof of the vehicle completes the pole retraction. The drive mechanism and traction rope enable rapid automatic return of the current collector pole, which is faster and more effective than manual return. Attached Figure Description

[0046] like Figures 1-7 As shown, this invention illustrates a current collector for a trolleybus according to one embodiment of the present invention. In this embodiment, to solve the technical problem that the current collector pole 3 cannot quickly and automatically return to its original position after being lowered, a device for traction to return the current collector pole 3 to its original position is provided at one end of the current collector pole 3. The base 1 of the current collector is set on the top of the trolleybus, and one end of the swing arm 2 is set on the base 1. The swing arm 2 can rotate, and the axis of rotation is perpendicular to the top of the trolleybus. One end of the swing arm 2 extends towards the front of the trolleybus, and one end of the current collector pole 3 is rotatably set on the swing arm 2, with the axis of rotation of the current collector pole 3 perpendicular to the swing arm 2. The axis of rotation extends from the other end of the current collector 3 toward the rear of the trolleybus. The current collector 3 can also rotate with the swing arm 2. A drive unit 4 is further provided on the base 1. The drive unit 4 is located below the swing arm 2. The drive unit 4 is preferably a cylinder, but it can also be a hydraulic cylinder or other device that can provide pulling force. There is no limitation here. The telescopic end of the drive unit 4 has a traction rope 5. The other end of the traction rope 5 is connected to the swing arm 2. The drive unit 4 can pull the current collector 3 to a direction parallel to the trolleybus body by telescopic movement. The traction rope 5 is preferably a steel wire rope, but it can also be other ropes with strength that can withstand the pulling force.

[0047] Specifically, after the trolleybus stops running, the current collector 3 deviates from the direction of the vehicle body due to external forces during the trolleybus's operation. It is necessary to rotate the current collector 3 to be parallel to the trolleybus body. The drive component 4 pulls the traction rope 5 to drive the swing arm 2 to rotate. Furthermore, the swing arm 2 drives the current collector 3 to rotate. When the traction rope 5 is pulled to be parallel to the trolleybus body, the current collector 3 is simultaneously parallel to the vehicle body, that is, the current collector 3 has returned to the correct position. Then, the current collector 3 is lowered to a position parallel to the roof of the vehicle to complete the retraction of the current collector 3. The design of the drive component 4 and the traction rope 5 enables the current collector 3 to return to the correct position quickly and automatically, which is faster and more effective than manual return.

[0048] like Figures 2-3 As shown, in this utility model, a connecting rod 301 is provided on the current collector rod 3, and a telescopic member 6 is connected to the connecting rod 301. The other end of the telescopic member 6 is connected to the swing arm 2. The telescopic member 6, the connecting rod, the current collector rod 3 and the swing arm 2 form a four-bar linkage mechanism, which can make the current collector rod 3 swing within a certain angle. The telescopic member 6 is preferably a cylinder, but it can also be a hydraulic cylinder or an electric motor, which is not limited here. An elastic member 7 is also connected between the swing arm 2 and the current collector rod 3. The elastic member 7 can provide the force for the current collector rod 3 to rise. The elastic member 7 is generally a tension spring. The telescopic member 6 can also provide an auxiliary force when the current collector rod 3 rises, and can also provide a thrust to overcome the elastic force of the elastic member 7 to make the current collector rod 3 fall.

[0049] Specifically, when the current collector pole 3 is about to rise, the elastic element 7 provides a pulling force to allow the current collector pole 3 to rise. The current collector pole 3 rises under the action of a four-bar linkage consisting of the telescopic element 6, the connecting rod, and the swing arm 2. Among them, the elastic element 7 provides the pulling force, the current collector pole 3 swings upward axially, and the telescopic element 6 swings and retracts through the hinge pin, so that the current collector pole 3 can reach the target position. During the rising process, the telescopic element 6 can provide a pulling force to assist the current collector pole 3 in rising, and it can also provide a pushing force to avoid the current collector pole 3 rising too fast and impacting the parts and the power grid. After the trolleybus stops running, the telescopic element 6 provides a pushing force to the current collector pole 3 to overcome the pulling force of the elastic element 7 and lower the current collector pole 3. The lowering process is similar to the rising process and will not be described in detail here. The setting of the telescopic element 6 and the elastic element 7 realizes the automatic lifting and lowering function of the current collector pole 3, avoiding manual operation and improving the driver's driving experience.

[0050] like Figures 4-5As shown, to prevent the current collector pole 3 from swaying after descent or deviating due to other factors, a limit assembly 8 is installed on the top of the trolleybus. The limit assembly 8 is located in the extension direction of the current collector pole 3. The limit assembly 8 has two rotatable limit hooks 801, which can hook the current collector pole 3 after descent. The limit assembly 8 also has a bracket 802 and a guide 803. The limit hooks 801 are set on the bracket 802, and the bracket 802 also has a device that can provide rotation for the limit hooks 801. The guide 803 is between the two limit hooks 801. The guide 803 can limit the movement direction of the current collector pole 3 when it descends, so that the current collector pole 3 accurately enters the limit hooks 801. A rope winder 9 is also installed at the rear of the trolleybus. The rope winder 9 has a pull rope that can provide tension to the current collector pole 3.

[0051] Specifically, when the current collector pole 3 descends, the limiting hook 801 rotates to both sides of the trolleybus, the rope reel 9 operates, and the pull rope pulls the current collector pole 3 downward. After the current collector pole 3 descends to the lowest position through the guide 803, the limiting hook 801 rotates to the position of the guide 803 and releases the pull rope. The current collector pole 3 springs back upward and gets stuck in the limiting hook 801. The setting of the limiting component 8 allows the current collector pole 3 to be fixed in one position after the trolleybus stops running, avoiding displacement caused by external forces after the trolleybus stops running, and also avoiding damage caused by the pull rope of the rope reel 9 being stretched taut for a long time.

[0052] like Figures 6-7 As shown, in this embodiment, the collector head base 10 is disposed at the extension end of the collector rod 3, and a rotating shaft 1001 is disposed on the collector head base 10. The collector head 11 is oscillatingly disposed on the rotating shaft 1001, and the oscillation axis of the collector head 11 is perpendicular to the axis of the rotating shaft 1001. The collector head 11 is provided with a receiving groove 1101, which can accommodate the wires on the power grid. The two ends of the conductor 12 are connected to the collector head and the collector head base.

[0053] Specifically, the collector pole 3 rises via the elastic element 7. During the rise, the collector head 11 contacts the wire through a limit or guide, and the wire enters the receiving groove 1101. The wire can provide the collector head 11 with a swinging force. When the vehicle turns or avoids obstacles, the pivot 1001 can ensure that the receiving groove 1101 is always parallel to the wire. When the vehicle encounters a bumpy road, the collector head 11 can swing to ensure that the bottom of the receiving groove 1101 is always in contact with the wire. The electricity in the power grid enters the collector pole 3 through the conductor 12. The electrical connection here is a conventional technical means and will not be described in detail here.

[0054] like Figure 6As shown, in this embodiment, a U-shaped block 1102 is also provided on the collector head 11. The U-shaped block 1102 can rotate or swing with the collector head 11. A thin plate 11021 is provided on one side of the U-shaped block 1102. The thin plate 11021 can remove foreign objects on the wire, such as ice hanging on the wire in winter, to prevent the collector head 11 from directly contacting foreign objects and to protect the collector head 11.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
