Description

Technical Field

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

[0002] 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 perpendicular to the track in the horizontal direction, and the station module is the power source for the charging pile. The transport trolley can move on the track, and the charging pile can be movably 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 is 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.

[0003] Existing rail-mounted mobile charging robots typically use a two-stage telescopic mechanism to retrieve or place charging piles. Specifically, the two-stage telescopic mechanism includes a drive unit, a primary guide rail, and a secondary guide rail. The primary guide rail is fixed to a transport trolley, while the secondary guide rail slides along and is connected to the charging pile. The drive unit drives the secondary guide rail to slide along the primary guide rail, thus extending the charging pile from the transport trolley to dock with the station module, completing the charging pile placement task. However, if the charging pile uses a high-power module, meaning it has a large load weight, the secondary telescopic mechanism may deform significantly, making it unable to properly retrieve or place the charging pile. Summary of the Invention

[0004] One of the main objectives of this invention is to provide a charging pile retrieval and placement device for a rail-mounted mobile charging robot. This device aims to solve the technical problem that when existing rail-mounted mobile charging robots use a two-stage telescopic mechanism to perform charging pile placement or retrieval tasks, the two-stage telescopic mechanism will deform significantly under heavy loads from the charging piles, making it impossible to complete the charging pile retrieval and placement tasks normally.

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

[0006] track;

[0007] A transport trolley is mounted on the track, and the transport trolley is provided with a first guide rail, which extends horizontally and is perpendicular to the track.

[0008] A charging pile is installed on the transport trolley. The charging pile is equipped with a roller assembly, which includes multiple rollers arranged in a row along the extension direction of the first guide rail. The multiple rollers are tactilely connected to the first guide rail.

[0009] The connecting rail extends horizontally and is perpendicular to the track, with one end of the connecting rail fixedly connected to the track;

[0010] The station module is fixedly connected to the other end of the connecting rail. The station module is provided with a second guide rail, which is coaxially connected to the first guide rail so that the roller can reciprocate on the first guide rail and the second guide rail.

[0011] Furthermore, the present invention also includes a drive assembly connected to the charging pile drive, for driving the charging pile to roll from the first guide rail to the second guide rail or from the second guide rail to the first guide rail.

[0012] Furthermore, there are two drive components, which are mirror-symmetrical about the connecting rail.

[0013] Furthermore, the drive assembly includes a connecting seat and a primary drive structure. The primary drive structure includes a primary gear drive mechanism and a primary rack. The primary rack is fixed to the charging pile, and the extension direction of the primary rack is parallel to the first guide rail. The primary gear drive mechanism is mounted on the transport trolley through the connecting seat. The primary gear drive mechanism meshes with the primary rack and is used to drive the primary rack to move the charging pile.

[0014] Furthermore, the drive assembly also includes a secondary drive structure, which is mounted on the transport trolley and is used to drive the primary gear drive mechanism to engage or disengage with the primary rack.

[0015] Furthermore, the secondary drive structure includes a secondary gear drive mechanism and a secondary rack. The secondary rack is fixed on the transport trolley, and the extension direction of the secondary rack is the same as that of the primary rack. The connecting seat is slidably disposed on the transport trolley, and the sliding direction of the connecting seat relative to the transport trolley is the same as that of the extension direction of the primary rack. The secondary gear drive mechanism is fixed on the connecting seat, and the secondary gear drive mechanism is drivenly connected to the secondary rack.

[0016] Furthermore, the primary gear drive mechanism includes a primary drive unit and a primary drive gear. The primary drive unit is fixed on the connecting seat, and the output end of the primary drive unit is drivenly connected to the primary drive gear. The primary drive gear meshes with the primary rack.

[0017] Furthermore, an adjustment device is horizontally provided on the connecting seat, which automatically adjusts the primary gear drive mechanism to always mesh with the primary rack.

[0018] Furthermore, the adjustment device includes an inclined guide rail, an adjusting spring, and a fixing block. The inclined guide rail is horizontally disposed on the connecting seat and is angled to the first-stage rack. The first-stage gear drive mechanism is slidably connected to the inclined guide rail and can slide along the inclined guide rail. The fixing block is fixed to the connecting seat. The extending direction of the adjusting spring is the same as the extending direction of the inclined guide rail. The opposite ends of the adjusting spring are respectively fixed to the first-stage gear drive mechanism and the fixing block.

[0019] Furthermore, the adjusting device also includes a stop member disposed on the connecting seat, the stop member being used to restrict the primary gear drive mechanism from disengaging from the inclined guide rail.

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

[0021] In use, the charging pile placement and retrieval device of the rail-mounted mobile charging robot of the present invention operates as follows: multiple rollers on the charging pile are rotatably connected to the first guide rail on the transport trolley, and the first guide rail on the transport trolley is coaxially connected to the second guide rail on the station module. Therefore, when the charging pile needs to be placed, the multiple rollers are driven from the first guide rail to the second guide rail, thus achieving the task of docking the charging pile with the station module, which is equivalent to realizing the task of placing the charging pile. When the charging pile needs to be retrieved, the multiple rollers are driven from the second guide rail to the first guide rail, thus disengaging the charging pile from the station module, which is equivalent to realizing the task of retrieving the charging pile.

[0022] In summary, this invention employs a rolling mechanism between rollers and guide rails to perform the task of retrieving or placing charging piles. This concentrates the weight of the charging pile onto the first and second guide rails, meaning that during the retrieving or placing process, the first and second guide rails support the charging pile. Compared to existing methods that use a two-stage telescopic mechanism, this invention ensures that the first and second guide rails will not easily deform even under heavy loads, thus guaranteeing the successful completion of the charging pile retrieval and placement tasks.

[0036] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] Please refer to Figures 1-11 This invention provides a charging pile 3 retrieval and placement device for a rail-mounted mobile charging robot, comprising a track 1, a transport trolley 2, a charging pile 3, a connecting rail 4, and a station module 5. The transport trolley 2 is mounted on the track 1 and can move on the track 1. A first guide rail 20 is provided on the transport trolley 2 and can be fixed to the transport trolley 2 by welding. The first guide rail 20 extends horizontally and is perpendicular to the track 1. The connecting rail 4 extends horizontally and is perpendicular to the track 1, with one end of the connecting rail 4 fixedly connected to the track 1. The station module 5 is fixedly connected to the other end of the connecting rail 4.

[0041] Of course, the connecting rail 4 and the track 1 are arranged perpendicularly to each other in space, so that the wheels of the transport trolley 2 can pass through the space between the connecting rail 4 and the track 1, thus enabling a single charging pile 3 to move to the station module 5 above different parking spaces.

[0042] In this embodiment, refer to Figure 1 and Figure 5 The connecting rail 4 can be fixedly connected to the rail 1 via a connector 40. The connector 40 extends vertically, and its position on the rail 1 avoids the path of the transport trolley 2 on the rail 1. In other words, the path of the transport trolley 2 on the rail 1 will not interfere with the position of the connector 40 on the rail 1. Furthermore, the charging pile 3 is mounted on the transport trolley 2. The charging pile 3 can move relative to the transport trolley 2, and the direction of movement of the charging pile 3 relative to the transport trolley 2 allows it to dock with the station module 5. That is, the direction of movement of the charging pile 3 relative to the transport trolley 2 is perpendicular to the horizontal direction of the rail 1. It should be noted here that, referring to… Figure 6 and Figure 8 The connection between the charging pile 3 and the station module 5 refers to the plugging and mating of the male charging connector 31 on the charging pile 3 and the female charging connector 51 on the station module 5.

[0043] To enable the charging pile 3 to move relative to the transport trolley 2, a set of rollers 30 is provided on the charging pile 3. The set of rollers 30 includes multiple rollers 30 arranged in a row along the extension direction of the first guide rail 20, and the multiple rollers 30 are tactilely connected to the first guide rail 20. To enable the charging pile 3 to dock with the station module 5, a second guide rail 50 is provided on the station module 5. The second guide rail 50 can be fixed to the station module 5 by welding. The second guide rail 50 and the first guide rail 20 can be coaxially connected, so that the rollers 30 can reciprocate on the first guide rail 20 and the second guide rail 50. As one application scenario, a station module 5 is reserved above each parking space. For example, when a new energy vehicle in parking space A needs to be charged, the transport trolley 2 can be controlled to move along the track 1 to transport the charging pile 3 to the station module 5 above parking space A. This makes the first guide rail 20 on the transport trolley 2 coaxially connected with the second guide rail 50 on the station module 5 above parking space A. At this time, the task of placing the charging pile 3 is performed. By driving the charging pile 3, multiple rollers 30 roll from the first guide rail 20 to the second guide rail 50, thus realizing the task of docking the charging pile 3 with the station module 5, which is to say, realizing the task of placing the charging pile 3. When it is necessary to perform the action of retrieving the charging pile 3, by driving the charging pile 3, multiple rollers 30 roll from the second guide rail 50 to the first guide rail 20, thus detaching the charging pile 3 from the station module 5, thus realizing the task of retrieving the charging pile 3.

[0044] In summary, this invention employs a structure where the roller 30 and the guide rail roll in a rolling manner to perform the task of retrieving or placing the charging pile 3. Thus, the weight of the charging pile 3 is concentrated on the first guide rail 20 and the second guide rail 50. In other words, during the process of retrieving or placing the charging pile 3, the first guide rail 20 and the second guide rail 50 support the charging pile 3. Compared to existing methods that use a two-stage telescopic mechanism to perform the task of retrieving or placing the charging pile 3, this invention ensures that even when the load weight of the charging pile 3 is large, the first guide rail 20 and the second guide rail 50 will not easily deform, thereby ensuring that the task of retrieving and placing the charging pile 3 can be completed normally.

[0045] It should be noted that the transport trolley 2 is rolled on the track 1, allowing it to move along the cabinet. This rolling arrangement of the transport trolley 2 on the track 1 is a common existing technology for rail-mounted mobile charging robots, and its specific arrangement will not be elaborated here. Furthermore, the number of the first guide rail 20 and the second guide rail 50 is not limited in this embodiment. For example, two of each type of guide rail are provided, with the two first guide rails 20 mirror images of the connecting rail 4, and the two second guide rails 50 mirror images of the connecting rail 4; alternatively, four of each type of guide rail may be provided.

[0046] In one embodiment, reference is made to Figures 1-4 The charging pile 3 picking and placing device of the rail-mounted mobile charging robot of the present invention also includes a driving component 6 that is driven to connect to the charging pile 3. The driving component 6 is used to drive the charging pile 3 to roll from the first guide rail 20 to the second guide rail 50 or from the second guide rail 50 to the first guide rail 20, thereby realizing the picking and placing action of the charging pile 3.

[0047] In one embodiment, reference is made to Figure 6 and Figure 7 The first guide rail 20 and the second guide rail 50 are connected at their respective ends by a first guide cone 201, which extends along the axial direction of the first guide rail 20. Similarly, the second guide rail 50 and the first guide rail 20 are connected at their respective ends by a second guide cone 501, which extends along the axial direction of the second guide rail 50. Thus, the connection between the first guide rail 20 and the second guide rail 50 is achieved through the connection of the first guide cone 201 and the second guide cone 501, ensuring that the roller 30 can smoothly transition from the first guide rail 20 to the second guide rail 50, or vice versa.

[0048] In one embodiment, there are two drive components 6, which are mirror-symmetrical about the connecting rail 4. That is, the power is symmetrically arranged on opposite sides of the station module 5 to provide good push and pull forces for picking up and placing the charging pile 3, ensuring the smoothness of the picking up and placing process of the charging pile 3, and ensuring the uniformity of the output force when picking up or placing the charging pile 3.

[0049] In one embodiment, reference is made to Figure 2 , Figure 9 , Figure 10 and Figure 11 The drive assembly 6 includes a connecting seat 60 and a primary drive structure. The primary drive structure includes a primary gear drive mechanism 61 and a primary rack 62. The primary rack 62 is fixed to the charging pile 3 by bolts. The extension direction of the primary rack 62 is parallel to the first guide rail 20. The primary drive structure is mounted on the transport trolley 2 via the connecting seat 60. The primary gear drive mechanism 61 meshes with the primary rack 62 to drive the primary rack 62, causing the charging pile 3 to move along the extension direction of the connecting rail 4, allowing the charging pile 3 to move to the station module 5 for docking.

[0050] In one embodiment, reference is made to Figure 2 , Figure 4 and Figures 9-11 The primary gear drive mechanism 61 includes a primary drive unit 610 and a primary drive gear 611. The primary drive unit 610 is a drive motor and is mounted on the transport trolley 2. The output end of the primary drive unit 610 is connected to the primary drive gear 611. The primary drive gear 611 meshes with a primary rack 62. The primary drive unit 610 drives the primary drive gear 611 to rotate, which in turn drives the primary rack 62 to move along the extension direction of the connecting rail 4. In other words, when a pile placement action is required, the primary drive unit 610 drives the primary rack 62 to extend the charging pile 3 from the transport trolley 2 and move it to dock with the station module 5. When a pile retrieval action is required, the primary drive unit 610 drives the primary rack 62 to disengage the charging pile 3 from the station module 5 and move it back onto the transport trolley 2.

[0051] Of course, in other embodiments, the primary gear drive mechanism 61 may also include a primary drive unit 610 and multiple meshing primary drive gears 611, which is not limited here. Therefore, by reasonably changing the structure of the primary gear drive mechanism 61, it should also fall within the protection scope of the present invention.

[0052] Based on the above structure, referring to Figure 2 , Figure 4 and Figures 9-11The drive assembly 6 also includes a secondary drive structure mounted on the transport trolley 2. This secondary drive structure drives the primary gear drive mechanism 61 to engage or disengage with the primary rack 62. Since the engagement of the primary drive gear 611 with the primary rack 62 occupies a certain distance of the rack 62, and the primary rack 62 is fixed to the charging pile 3, the transmission of the engagement of the primary drive gear 611 with the primary rack 62 cannot allow the charging pile 3 to fully extend outside or fully retract onto the transport trolley 2. Therefore, the secondary drive structure drives the primary drive gear 611 of the primary gear drive mechanism 61 to engage or disengage with the primary rack 62, allowing the charging pile 3 to fully extend outside or fully retract onto the transport trolley 2.

[0053] In one embodiment, reference is made to Figure 2 , Figure 4 and Figures 9-11 The secondary drive structure includes a secondary gear drive mechanism 63 and a secondary rack 64. The secondary rack 64 is fixed to the transport trolley 2, and its extension direction is the same as that of the primary rack 62. The secondary gear drive mechanism 63 is slidably mounted on the transport trolley 2. Specifically, the secondary gear drive mechanism 63 is fixed to a connecting seat 60, which in turn is slidably mounted on the transport trolley 2. A guide rail 32 is horizontally fixed on the transport trolley 2. The extension direction of the guide rail 32 is parallel to that of the secondary rack 64, and the guide rail 32 and the secondary rack 64 are located on the same plane. Thus, the connecting seat 60 is slidably connected to the guide rail 32 via a slider, ensuring that the sliding direction of the secondary gear drive mechanism 63 relative to the transport trolley 2 is the same as the extension direction of the primary rack 62. Of course, the secondary gear drive mechanism 63 and the secondary rack 64 are driven together. Therefore, it can be understood that during the meshing transmission of the secondary gear drive mechanism 63 and the secondary rack 64, the connecting seat 60 slides along the guide rail, causing the secondary gear drive mechanism 63 to slide along the guide rail, thereby driving the charging pile 3 to be fully pushed out of the transport trolley 2 or fully retracted onto the transport trolley 2. When the charging pile 3 is fully pushed out of the transport trolley 2 and docked with the station module 5, the primary drive gear 611 can disengage from the primary rack 62. When the pile retrieval action needs to be performed, as long as the meshing transmission of the secondary gear drive mechanism 63 and the secondary rack 64 drives the secondary gear drive mechanism 63 to extend a short distance from the transport trolley 2 along the extension direction of the primary rack 62, the primary drive gear 611 can hook onto the primary rack 62, realizing the meshing of the primary gear drive mechanism 61 and the primary rack 62, completing the pile retrieval and placement action of the charging pile 3, with rapid transmission.

[0054] In one embodiment, reference is made to Figure 2 , Figure 9 , Figure 10 and Figure 11 The connecting seat 60 is slidably mounted on the transport trolley 2. The sliding direction of the connecting seat 60 relative to the transport trolley 2 is the same as the extension direction of the first-stage rack 62 or the second-stage rack 64. The second-stage gear drive mechanism 63 is fixed to the connecting seat 60. That is, the second-stage gear drive mechanism 63 is slidably connected to the guide rail mentioned above through the connecting seat 60. The meshing transmission between the second-stage gear drive mechanism 63 and the second-stage rack 64 drives the connecting seat 60 to move along the extension direction of the first-stage rack 62, thereby driving the second-stage gear drive mechanism 63 to move along the extension direction of the first-stage rack 62.

[0055] In one embodiment, reference is made to Figure 2 , Figure 9 , Figure 10 and Figure 11 The secondary gear drive mechanism 63 includes a secondary drive unit 630 and a secondary drive gear 631. The secondary drive unit 630 is a drive motor and is fixed on the connecting seat 60. The output end of the secondary drive unit 630 is driven by the secondary drive gear 631, and the secondary drive gear 631 meshes with the secondary rack 64.

[0056] Of course, in other embodiments, the secondary gear drive mechanism 63 may also include a secondary drive unit 630 and multiple meshing secondary drive gears 631, which is not limited here. Therefore, by reasonably changing the structure of the secondary gear drive mechanism 63, it should also fall within the protection scope of the present invention.

[0057] In one embodiment, reference is made to Figure 2 , Figures 9-11 The connecting seat 60 is also equipped with a horizontally adjustable device, which automatically adjusts the primary gear drive mechanism 61 to always mesh with the primary rack 62. In other words, because there is an installation error in the primary drive gear 611, the adjustable device allows the primary drive gear 611 to float in its radial direction, ensuring that the primary drive gear 611 always meshes with the primary rack 62. This eliminates the installation error of the primary drive gear 611 and avoids damage to the primary drive unit 610 due to excessive output torque caused by the primary drive gear 611 not fully meshing with the primary rack 62.

[0058] In one embodiment, reference is made to Figure 2 , Figures 9-11The adjustment device includes an inclined guide rail 7, which is horizontally mounted on the connecting seat 60. The inclined guide rail 7 is angled to the primary rack 62. The primary gear drive mechanism 61 is slidably connected to the inclined guide rail 7, allowing the primary gear drive mechanism 61 to slide along the inclined guide rail 7. Furthermore, the adjustment device also includes an adjusting spring 70 and a fixing block 71. The fixing block 71 is fixed to the connecting seat 60. The extending direction of the adjusting spring 70 is the same as the extending direction of the inclined guide rail 7. The opposite ends of the adjusting spring 70 are respectively fixed to the primary gear drive mechanism 61 and the fixing block 71. Specifically, the primary gear drive mechanism 61 is connected and fixed to the adjusting spring 70 via the motor mounting base 8. Of course, the motor mounting base 8 is slidably connected to the inclined guide rail 7 via a slider. Thus, when the primary drive gear 611 meshes with the primary rack 62 and is subjected to force, the primary drive gear 611 can float in its radial direction under the action of the adjusting spring 70, automatically adapting to mesh with the primary rack 62. This ensures that the primary drive gear 611 can always mesh with the primary rack 62, reducing the processing difficulty of the primary drive gear 611 and providing sufficient push and pull force for the charging pile 3 to pick up and place the pile, thereby ensuring that the task of picking up and placing the charging pile 3 can be completed smoothly.

[0059] In addition, refer to Figure 9 The adjusting device also includes a stop member 73, which is disposed on the connecting seat 60. The stop member 73 is used to prevent the primary gear drive mechanism 61 from disengaging from the inclined guide rail 7. The stop member 73 and the fixing block 71 are respectively located at opposite ends of the inclined guide rail 7. The stop member 73 can prevent the primary gear drive mechanism 61 from disengaging from the inclined guide rail 7. At the same time, the stop member 73 also restricts the primary gear drive mechanism 61 from pulling the adjusting spring 70, thereby preventing damage to the adjusting spring 70 and extending the service life of the adjusting spring 70.

[0060] In one embodiment, reference is made to Figure 9 or Figure 10 A tension adjusting component 72 is threadedly connected to the fixing block 71. The extension direction of the tension adjusting component 72 is the same as the extension direction of the inclined guide rail 7. The end of the adjusting spring 70 facing away from the motor mounting base 8 is connected and fixed to the adjusting component. Thus, the elastic extension and contraction of the adjusting spring 70 can be adjusted through the threaded connection between the tension adjusting component 72 and the fixing block 71, thereby achieving the effect of adjusting the tension. Specifically, the fixing block 71 has threaded holes penetrating its opposite sides. The extension direction of the threaded holes is the same as the extension direction of the inclined guide rail 7. The tension adjusting component 72 is threadedly connected to the threaded holes, and the end of the adjusting spring 70 facing away from the motor mounting base 8 is located in the threaded holes and connected and fixed to the tension adjusting component 72. This allows for the adjustment of the tension of the spring 70.
