Description

Technical Field

[0001] This invention relates to the field of charging robot technology, and in particular to a positioning and clamping device for a rail-mounted mobile charging robot. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the number of charging piles is increasing year by year. The existing charging mode is mostly to install one charging pile per parking space, resulting in low utilization efficiency of charging piles; in order to reduce construction costs and grid pressure, rail-mounted mobile charging robots are gradually emerging.

[0003] Currently, existing rail-mounted mobile charging robots include a track, a transport trolley, a charging pile, and a station module. The station module is fixed on the track and serves as the power source for the charging pile. The transport trolley can move along the track, and the charging pile is movable and mounted on the transport trolley. One station module can be reserved above each parking space. When a new energy vehicle in a parking space needs charging, the transport trolley can be controlled to move along the track, transport the charging pile to the station module, and perform the task of placing the charging pile, thus completing the docking between the charging pile and the station module. However, when the charging pile has a high charging power, i.e., when the charging pile is heavy, the placement and removal of the charging pile will cause a shift in the center of gravity of the transport trolley. Due to insufficient rigidity between the transport trolley and the station module, the docking between the charging pile and the station module is inaccurate, failing to provide good working conditions for the placement and removal of the charging pile. Summary of the Invention

[0004] One of the main objectives of this invention is to provide an alignment and clamping device for a rail-mounted mobile charging robot. This device aims to solve the problem that existing rail-mounted mobile charging robots have high charging power, meaning that when the charging piles are heavy, the center of gravity of the transport trolley changes due to the removal and placement of the charging piles. This results in inaccurate docking between the charging piles and the station module due to insufficient rigidity between the transport trolley and the station module, thus failing to provide good working conditions for placing and removing the charging piles.

[0005] To achieve the above objectives, the present invention provides an alignment and clamping device for a rail-mounted mobile charging robot, comprising:

[0006] track;

[0007] A transport trolley is positioned on the track and can travel along the track;

[0008] A connecting rail extends horizontally and is perpendicular to the track. The first end of the connecting rail is fixed to the track, and the second end of the connecting rail is used to fix the station module of the rail-mounted mobile charging robot.

[0009] A charging pile is mounted on the transport trolley and can move relative to the transport trolley so that the charging pile can be moved to dock with the station module;

[0010] At least one clamping mechanism is provided on the transport trolley. The at least one clamping mechanism includes a drive unit and two clamping components. Each clamping component is slidably disposed on the transport trolley. The drive unit is used to drive the two clamping components to clamp the opposite sides of the connecting rail respectively.

[0011] Furthermore, the two clamping components clamp the opposite sides of the connecting rail in a figure-eight shape.

[0012] Furthermore, the clamping assembly includes a guide rail and a sliding assembly. The guide rail is disposed on the transport trolley, and the two guide rails are arranged in a figure-eight shape. The sliding assembly is slidably disposed on the guide rail and can slide along the extension direction of the guide rail. The driving unit is drivenly connected to the sliding assembly to drive the two sliding assemblies to clamp the opposite sides of the connecting rail. In the state where the two sliding assemblies clamp the connecting rail, the two clamping assemblies are symmetrical about the connecting rail.

[0013] Further, the driving unit includes an electric push rod, the telescopic end and the fixed end of which are respectively hinged to the sliding component of one clamping assembly and the sliding component of another clamping assembly; when the telescopic end of the electric push rod retracts to its limit retraction position, the sliding component moves along the guide rail to a first limit position and abuts against a first limiting post located at the first limit position, and the sliding component clamps the connecting rail; when the telescopic end of the electric push rod extends to its limit extension position, the sliding component moves along the guide rail to a second limit position and abuts against a second limiting post located at the second limit position; wherein, the first limiting post, the second limiting post and the guide rail are located on the same plane, and the first limiting post and the second limiting post are perpendicular to the guide rail.

[0014] Furthermore, the sliding assembly includes a sliding seat and a clamping block, the sliding seat being slidably disposed on the guide rail, and the clamping block being fixed to one end of the sliding seat near the connecting rail.

[0015] Furthermore, the clamping mechanism also includes at least two L-shaped connecting blocks, each L-shaped connecting block corresponding to one of the two clamping components. Each L-shaped connecting block includes a connecting portion and a limiting portion. The connecting portions of the two L-shaped connecting blocks are respectively fixed to the opposite side walls of the connecting rail. The sliding component has a limiting groove adapted to the limiting portion on its end face facing the L-shaped connecting block.

[0016] Furthermore, an inclined portion is provided between the limiting portion and the connecting portion, and the opposite ends of the inclined portion are respectively connected to the connecting portion and the limiting portion, and the surface of the inclined portion is an inclined surface; wherein, when the two clamping components clamp the connecting rail, the opposite two sides in the limiting groove respectively engage with the inclined surface and the bottom surface of the limiting portion, and the end face of the clamping component with the limiting groove abuts against the side of the connecting portion facing away from the connecting rail.

[0017] Furthermore, the angle formed between the inclined surface and the limiting part is 30 to 35°.

[0018] Furthermore, a guide slope is provided on the inclined surface, and the angle between the guide slope and the inclined surface is 170 to 175°. The guide slope is located at the end of the inclined surface away from the connecting part.

[0019] Furthermore, the connecting rail is arranged perpendicularly to the track in a spatially intersecting manner, and there are two clamping mechanisms, which are located on opposite sides of the track.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In use, the alignment and clamping device of the rail-mounted mobile charging robot of the present invention involves a transport trolley moving along a track to move a charging pile to correspond with a station module fixed on a connecting rail. Then, a drive unit drives two clamping components to clamp the opposite sides of the connecting rail, making the transport trolley and the station module integrated, thus improving the overall rigidity between the transport trolley and the station module. With the two clamping components clamping the opposite sides of the connecting rail, the charging pile placement operation begins, that is, the charging pile is driven to move relative to the transport trolley to dock with the station module, completing the electrical connection between the charging pile and the station module, thereby realizing the task of placing the charging pile.

[0022] In summary, the alignment and clamping device of the rail-mounted mobile charging robot of the present invention clamps the connecting rail in an external gripping manner, so that the transport trolley and the station module are integrated into one, which improves the overall rigidity of the transport trolley and the station module. It will not cause inaccurate docking between the charging pile and the station module due to insufficient rigidity between the transport trolley and the station module, and provides good working conditions for the placement and removal of the charging pile.

[0032] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0033] In the description of this invention, it should be understood that the terms "width", "upper", "lower", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] Please refer to Figures 1-7 This invention provides a positioning and clamping device for a rail-mounted mobile charging robot, comprising a track 1, a connecting rail 2, a transport trolley 3, a charging pile 4, and at least one clamping mechanism 5. The connecting rail 2 extends horizontally and is perpendicular to the track 1. A first end of the connecting rail 2 is fixed to the track 1, and a second end is used to fix a station module 6 of the rail-mounted mobile charging robot. The transport trolley 3 is mounted on the track 1 and can move along the track 1. The charging pile 4 is mounted on the transport trolley 3 and can move relative to the transport trolley 3, and the movement of the charging pile 4 relative to the transport trolley 3 allows the charging pile 4 to dock with the station module 6. Furthermore, the clamping mechanism 5 is mounted on the transport trolley 3 and includes a drive unit 50 and two clamping components 51. Each clamping component 51 is slidably mounted on the transport trolley 3. The drive unit 50 drives the two clamping components 51 to clamp the opposite sides of the connecting rail 2 respectively.

[0037] In summary, when the alignment and clamping device of the rail-mounted mobile charging robot of the present invention is in use, the transport trolley 3 moves on the track 1 to move the charging pile 4 to correspond with the station module 6 fixed on the connecting rail 2. Then, the drive unit 50 drives the two clamping components 51 to clamp the opposite sides of the connecting rail 2 respectively, so that the transport trolley 3 and the station module 6 are integrated, thereby improving the overall rigidity between the transport trolley 3 and the station module 6. With the two clamping components 51 clamping the opposite sides of the connecting rail 2 respectively, the charging pile 4 is placed, that is, the charging pile 4 is driven to move relative to the transport trolley 3, so that the charging pile 4 moves to dock with the station module 6, and completes the electrical connection between the charging pile 4 and the station module 6, thereby realizing the task of placing the charging pile. As can be seen from the above, the present invention uses an external clamping method to clamp the connecting rail 2, so that the transport trolley 3 and the station module 6 are integrated, which improves the overall rigidity of the transport trolley 3 and the station module 6. It will not cause inaccurate docking between the charging pile 4 and the station module 6 due to insufficient rigidity between the transport trolley 3 and the station module 6, and provides good working conditions for the placement and removal of the charging pile 4.

[0038] It should be noted that the transport trolley 3 is rolled on the track 1 so that it can move along the extension direction of the track 1. Since the rolling arrangement of the transport trolley 3 on the track 1 is a common existing technology for track-mounted mobile charging robots, it will not be described in detail here.

[0039] In addition, the docking of charging pile 4 and station module 6 means that the male charging connector on charging pile 4 and the female charging connector on station module 6 are plugged in to make the charging pile 4 and station module 6 electrically connected.

[0040] In one embodiment, reference is made to Figure 3 One end of the connecting rail 2 is connected and fixed to the track 1 via a connector 21. The connector 21 extends vertically, and the connecting rail 2 and the track 1 are arranged perpendicularly to each other in a spatial intersection. This allows the rollers of the transport trolley 3 that travel on the track 1 to pass through the space between the connecting rail 2 and the track 1, thus enabling a single charging pile 4 to move to the station module 6 above different parking spaces. The connector 21 can be fixed to the track 1 by bolts or welded to the track 1.

[0041] As one application scenario, a station module 6 is reserved above each parking space. When a new energy vehicle in a parking space needs to be charged, the transport trolley 3 can be controlled to walk along the track 1 to transport the charging pile 4 to the station module 6 and perform the task of placing the charging pile 4, thus completing the placement of the charging pile 4 and the docking of the charging pile 4 with the station module 6. When the task of retrieving the charging pile needs to be performed, the charging pile can be driven to detach from the station module 6, so that the charging pile moves back onto the transport trolley.

[0042] Of course, whether performing pile placement or pile removal tasks, the two clamping components 51 are always in the state of clamping the connecting rail 2, so that the transport trolley 3 and the station module 6 are integrated, providing good working conditions for the placement or removal of the charging pile 4.

[0043] It should be noted that the charging pile 4 uses an existing two-stage telescopic mechanism to slide and connect with the transport trolley 3. The direction in which the charging pile 4 slides out of the transport trolley 3 faces the station module 6, and the track 1 extending from the transport trolley 3 is perpendicular in the horizontal direction, allowing the charging pile 4 to extend out of the transport trolley 3 and dock with the station module 6. The two-stage telescopic mechanism may include a first slide rail and a second slide rail, with the first slide rail slidably connected to the second slide rail. The first slide rail is fixed to the transport trolley 3, and the second slide rail is fixed to the clamping mechanism 5. This allows the charging pile 4 to dock with the station module 6. Since the two-stage telescopic mechanism is a common structure for existing rail-mounted mobile charging robots, it will not be described in detail here.

[0044] In one embodiment, reference is made to Figure 2 , Figure 3 and Figure 4 Since the connecting rail 2 is located above the track 1 and the connecting rail 2 and the track 1 are on different planes, the two clamping components 51 are designed to clamp the opposite sides of the connecting rail 2 in a figure-eight shape, which can save space in the vertical direction. The following is a detailed explanation of how the two clamping components 51 clamp the connecting rail 2 in a figure-eight shape: The clamping component 51 includes a guide rail 510 and a sliding component. The guide rail 510 is set at an angle on the transport trolley 3. The two guide rails 510 have a figure-eight structure and are symmetrical about the connecting rail 2. The sliding component is slidably set on the guide rail 510 so that the two sliding components can clamp the opposite sides of the connecting rail 2 respectively; of course, the two sliding components are also symmetrical about the connecting rail 2. By driving the two sliding components to slide along the two guide rails 510 respectively through the driving unit 50, the two sliding components can clamp the opposite sides of the connecting rail 2.

[0045] In one embodiment, reference is made to Figure 2 or Figure 3 The sliding assembly includes a sliding seat 511 and a clamping block 512. The sliding seat 511 is slidably disposed on the guide rail 510, and the clamping block 512 is fixed to one end of the sliding seat 511 near the connecting rail 2. Thus, the driving unit 50 drives the two sliding seats 511 to slide along the two guide rails 510 respectively, so that the two clamping blocks 512 clamp the connecting rail 2.

[0046] In one embodiment, the clamping mechanism 5 further includes at least two L-shaped connecting blocks 20, each corresponding to one of the two clamping components 51, and the two L-shaped connecting blocks 20 are symmetrically mirrored about the connecting rail 2; see reference Figure 5The L-shaped connecting block 20 includes an integrally connected connecting portion 201 and a limiting portion 202. The connecting portions 201 of the two L-shaped connecting blocks 20 are respectively fixed to the opposite side walls of the connecting rail 2. The connecting rail 2 and the connecting portion 201 can be fixed by welding or bolts. A limiting groove 5120 adapted to the limiting portion 202 is provided on the end face of the sliding component facing the L-shaped connecting block. The limiting groove 5120 is also provided on the end face of the clamping block 512 facing the connecting rail 2. Therefore, by connecting the connecting portion 201 of the L-shaped connecting block to the connecting rail 2, and then driving the clamping component 51 to slide along the guide rail 510 via the driving unit 50, the limiting groove 5120 on the clamping component 51 is inserted into the limiting portion 202 of the L-shaped connecting block. This increases the friction between the clamping component 51 and the connecting rail 2, further enhancing the clamping force of the two clamping components 51 on the connecting rail 2.

[0047] In one embodiment, reference is made to Figures 2-6 An inclined portion 203 is provided between the limiting portion 202 and the connecting portion 201. The two opposite ends of the inclined portion 203 are connected to the connecting portion 201 and the limiting portion 202 respectively. The surface of the inclined portion 203 is an inclined surface 2031. When the two clamping components 51 clamp the connecting rail 2, the two opposite sides of the limiting groove 5120 respectively engage with the inclined surface 2031 and the bottom surface of the limiting portion 202. The end face of the clamping component 51 with the limiting groove 5120 abuts against the side of the connecting portion 201 facing away from the connecting rail 2. In other words, the limiting groove 5120 has a "V" shaped structure. The end face of the clamping block 512 facing the connecting rail 2 is designated as the working surface 5121, and the end face of the clamping block 512 facing away from the connecting rail 2 is designated as the connecting surface 5122. Thus, the limiting groove 5120 extends from the working surface 5121 towards the connecting surface 5122. Of course, the limiting groove 5120 does not penetrate the connecting surface 5122. Therefore, when the clamping block 512 clamps the connecting rail 2, the working surface 5121 of the clamping block 512 abuts against the connecting part 201, and the two opposite sides of the limiting groove 5120 respectively engage with the inclined surface 2031 and the bottom surface of the limiting part 202, thereby greatly increasing the clamping force of the clamping block 512 on the connecting rail 2, and further improving the overall rigidity between the transport trolley 3 and the station module 6.

[0048] In one embodiment, reference is made to Figure 5The angle formed between the inclined surface 2031 and the limiting part 202 is A, which is 30° to 35°. In this embodiment, the angle formed between the inclined surface 2031 and the limiting part 202 is 30°, which reduces the output force of the drive unit 50. Of course, in other embodiments, the angle formed between the inclined surface 2031 and the limiting part 202 can also be 35°. In addition, it should be noted that the angle formed between the inclined surface 2031 and the limiting part 202 cannot exceed 45°. If it exceeds 45°, the clamping block 512 will not be able to clamp the connecting rail 2, resulting in insufficient rigidity between the station module 6 and the transport trolley 3. At the same time, it will greatly increase the output force of the drive unit 50, and may even damage the drive unit 50 due to excessive output force.

[0049] In one embodiment, a guide slope 2032 is provided on the inclined surface 2031, as shown in the figure. Figure 5 The angle formed between the inclined surface and the inclined surface 2031 is B, which is 170° to 175°. The guide inclined surface 2032 is located at the end of the inclined surface 2031 away from the connecting part 201. That is to say, the guide inclined surface 2032 can facilitate the upper surface of the limiting groove 5120 to slide into the inclined surface 2031 and engage with it, and at the same time, it can also help to improve the engagement force of the limiting groove 5120 on the inclined part 203 and the limiting part 202.

[0050] In one embodiment, reference is made to Figures 2-3 The drive unit 50 includes an electric push rod. The telescopic end of the electric push rod is hinged to the sliding component of a clamping assembly 51, that is, the telescopic end of the electric push rod is hinged to the sliding seat 511. The fixed end of the electric push rod is hinged to the sliding component of another clamping assembly 51, that is, the fixed end of the electric push rod is hinged to the sliding seat 511 of another clamping assembly 51. When the clamping assembly 51 clamps the connecting rail 2, the electric push rod is in a horizontal state. When the clamping assembly 51 disengages from the connecting rail 2, the electric push rod is also in a horizontal state. Specifically, when the telescopic end of the electric push rod is in its retracted limit state (meaning the telescopic end of the electric push rod is in its retracted limit extended position), the two clamping components 51 clamp the connecting rail 2; when the telescopic end of the electric push rod is in its extended state, the two clamping components 51 loosen the connecting rail 2; when the telescopic end of the electric push rod is in its extended limit state (meaning the telescopic end of the electric push rod is in its extended limit extended position), if the transport trolley 3 moves along the track 1 and drives the clamping mechanism 5 to move, the clamping components 51 will not interfere with the connecting rail 2, thereby enabling the transport trolley 3 to move the clamping mechanism 5 from one station module 6 to another station module 6.

[0051] It should be noted that when the telescopic end of the electric actuator retracts to its maximum retracted position, the sliding component moves along the guide rail 510 to the first limit position (the position reached when the telescopic end of the electric actuator retracts to its maximum retracted position, causing the sliding component to move along the extension direction of the guide rail 510) and abuts against the first limiting post 513 located at the first limit position; when the telescopic end of the electric actuator extends to its maximum extended position, the sliding component moves along the guide rail 510 to the second limit position (the position reached when the telescopic end of the electric actuator extends to its maximum extended position, causing the sliding component to move along the extension direction of the guide rail 510) and abuts against the second limiting post 514 located at the second limit position; wherein, the second limiting post 514, the first limiting post 513 and the guide rail 510 are located on the same plane, and the first limiting post 513 is perpendicular to the guide rail 510, and the second limiting post 514 is perpendicular to the guide rail 510. Therefore, it can be understood that during the extension of the telescopic end of the electric push rod, when the sliding seat 511 in one clamping assembly 51 slides down along the guide rail 510 in the clamping assembly 51 to abut against the second limiting post 514 fixed on the guide rail 510 in the clamping assembly 51, the second limiting post 514 restricts the sliding seat 511 from continuing to slide down along the guide rail 510. As the telescopic end of the electric push rod continues to extend, the sliding seat 511 in the other clamping assembly 51 slides down along the guide rail 510 in the other clamping assembly 51. When the sliding seat 511 in the other clamping assembly 51 slides down along the guide rail 510 in the other clamping assembly 51 to abut against the second limiting post 514 fixed on the guide rail 510 in the other clamping assembly 51, the telescopic end of the electric push rod is just at the limit extension position, and the electric push rod is in a horizontal state.

[0052] Similarly, during the retraction of the telescopic end of the electric actuator, when the sliding seat 511 in one clamping assembly 51 slides up along the guide rail 510 in the clamping assembly 51 and abuts against the first limiting post 513 fixed on the guide rail 510 in the clamping assembly 51, the limiting groove 5120 in the clamping assembly 51 just engages with the limiting part 202 and the inclined part 203 in the clamping assembly 51. At the same time, the working surface 5121 on the clamping block 512 in the clamping assembly 51 also just abuts against the connecting part 201 on the L-shaped connecting block. As the telescopic end of the electric actuator continues to retract, the sliding seat 511 in the other clamping assembly 51 slides up along the guide rail 510 in the other clamping assembly 51. When the sliding seat 511 in the other clamping assembly 51 slides up along the guide rail 510 in the other clamping assembly 51 to abut against the first limiting post 513 fixed on the guide rail 510 in the other clamping assembly 51, the limiting groove 5120 in the other clamping assembly 51 just engages with the limiting part 202 and the inclined part 203 in the other clamping assembly 51. At the same time, the working surface 5121 on the clamping block 512 in the other clamping assembly 51 also just abuts against the connecting part 201 on the other L-shaped connecting block. When the telescopic end of the electric push rod is just at the limit retraction position of the telescopic rod of the electric push rod, the electric push rod is in a horizontal state, and the two clamping assemblies 51 clamp the connecting rail 2.

[0053] In summary, using one drive unit 50 can simultaneously drive two clamping components 51 to clamp the connecting rail 2, which not only saves the installation space of the drive unit 50, but also saves the cost of the drive unit 50, thereby reducing the overall size and manufacturing cost of the alignment clamping device of the rail-mounted mobile charging robot of the present invention.

[0054] Of course, in other embodiments, the electric actuator can be replaced by a pneumatic cylinder or a hydraulic cylinder, which is not limited here.

[0055] In one embodiment, reference is made to Figure 7 There are two clamping mechanisms 5, which are located on opposite sides of the track 1, so that there are clamping mechanisms 5 on both sides of the track 1. Therefore, when the clamping mechanisms 5 have completed clamping, the transport trolley 3 and the connecting rail 2 are integrated as a whole. Because there are clamps on both sides of the track 1, the bending and torsion resistance is strong, and the overall deformation is small when transporting high-power modules, i.e., heavy modules.

[0056] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
