Description

Technical Field

[0001] This disclosure pertains to the field of battery swapping technology, and in particular to a front-mounted battery swapping device and a battery swapping station with deflection function. Background Technology

[0002] Replaceable battery boxes are typically mounted on a vehicle's bracket using a movable installation method. The vehicle then replaces the battery box using a battery swapping device. After the replaced battery box is fully charged, it is reinstalled on the vehicle using the same device. For electric trucks, especially heavy-duty electric trucks, the battery boxes are usually replaceable. When a vehicle needs a battery box replacement, it simply drives to a battery swapping station, where the replacement can be completed using the swapping equipment.

[0003] In front-mounted battery swapping equipment, the battery box is loaded along the direction of movement of the equipment, such as in front or behind it. Compared to side-moving battery swapping equipment, this type of equipment is more compact and occupies less space. However, due to angle deviations during vehicle parking or errors in the placement angle of the battery box, the gripping mechanism of the front-mounted battery swapping equipment may have difficulty accurately engaging the battery box, preventing the equipment from completing the swapping operation. Summary of the Invention

[0004] In view of the above, it is necessary to provide a front-mounted battery swapping device and battery swapping station with deflection function, which aims to improve the battery swapping device's ability to adapt to the angle of the battery box and dock with the battery box.

[0005] Therefore, this disclosure first provides a front-mounted battery swapping device with deflection function, comprising:

[0014] According to the aforementioned front-mounted battery swapping device with deflection function, the support assembly includes a gripping guide rail and a gripping slider. One of the gripping guide rail and the gripping slider is connected to the gripping member, and the other is connected to the cantilever beam. The gripping member moves along the gripping guide rail via the gripping slider.

[0015] According to the aforementioned front-mounted battery swapping device with deflection function, the gripping mechanism further includes a gripping motor, a drive wheel, and a traction rope. The gripping motor is located at the inner end of the cantilever beam, the drive wheel is rotatably connected to the cantilever beam, and the traction rope is connected to the gripping motor and passes around the drive wheel to connect to the gripping component. The gripping motor drives the gripping component to move vertically through the traction rope.

[0016] According to the aforementioned front-mounted battery swapping device with deflection function, the cantilever beam includes a first connection and a second connection located on both sides of the cantilever beam along the vertical direction, and the cantilever beam is movably connected to the frame at the first connection and the second connection along a second direction.

The column extends vertically, and the first and second connecting beams extend horizontally and are detachably connected to the column. The first connecting beam is movably connected to the cantilever beam at the first connection point, and the second connecting beam is movably connected to the cantilever beam at the second connection point.

[0018] According to the aforementioned front-mounted battery swapping device with deflection function, at least one of the first connecting beam and the second connecting beam is connected to the column via a plurality of shims to adjust the angle of the cantilever beam in the vertical direction.

[0019] The front-mounted battery swapping device with deflection function further includes a traveling mechanism connected to the frame, which drives the frame to move along the first direction, and the cantilever beam extends along the first direction in its length direction.

[0023] The aforementioned front-mounted battery swapping device with deflection function is used to move across the battery storage area along a first direction, and loads the battery box on the side of the battery swapping device in the first direction to transport the battery box.

[0024] Compared to existing technologies, the aforementioned front-mounted battery swapping equipment and battery swapping station with deflection function connects the gripping mechanism to the outer end of the cantilever beam. The gripping component of the gripping mechanism is rotatably connected to the outer end of the cantilever beam. When it is necessary to dock with the battery box, the gripping component can rotate relative to the cantilever beam at the outer end of the cantilever beam, thereby adjusting the angle of the gripping component of the gripping mechanism relative to the battery box, and completing the docking with the battery box through the gripping mechanism.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0041] In each embodiment, for ease of description and not limitation of this disclosure, the term "connection" used in this application specification and claims is not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Above," "below," "under," "left," "right," etc., are only used to indicate relative positional relationships, and when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0042] Figure 1 This is a structural diagram of a battery swapping station. (For example...) Figure 1As shown, the front-mounted battery swapping station includes a front-mounted battery swapping device 10 with deflection function, a battery storage area 40, and a battery box 30. The battery storage area 40 is equipped with multiple battery holders 31, which can be one or more, arranged in an array within the swapping area. The battery box 30 is mounted on the battery holders 31 and used to store the battery boxes 30. In some embodiments, the battery holders 31 can also charge the placed battery boxes 30. The battery swapping device 10 is movably connected to both sides of the battery storage area 40 in a first direction, spanning the battery storage area 40, and moves back and forth above the battery box 30 along the first direction (i.e., the X direction). The parking space is located at the end of the battery storage area 40 in the first direction. The front-mounted battery swapping device 10 loads the battery box 30 onto the side in the first direction to transport the battery box 30, thus completing the battery box 30 replacement for the vehicle 20.

[0043] When it is necessary to replace the battery box 30 of vehicle 20, vehicle 20 is parked in a parking space located at the end of battery storage area 40 along the first direction in a second direction (i.e., the Y direction) that is generally perpendicular to the first direction. The battery swapping equipment 10 is moved along the X direction to a position close to the parking space, the depleted battery box 30 is removed from vehicle 20 and moved along the X direction, the depleted battery box 30 is transported to a battery holder 31 in battery storage area 40, and the fully charged battery box 30 on the other battery holder 31 is moved to vehicle 20, thus completing the battery swapping operation for vehicle 20.

[0044] Figure 2 This is a structural schematic diagram of the power swapping device 10. (For example...) Figure 2 As shown, the front-mounted battery swapping device 10 with deflection function includes a frame 11, a traveling mechanism 12, a cantilever beam 13, and a gripping mechanism 14. The frame 11 is used to support other mechanisms and components of the battery swapping device 10, the traveling mechanism 12 is used to drive the frame 11 to move back and forth along the length of the aisle, the cantilever beam 13 is used to support the gripping mechanism 14, and the gripping mechanism 14 is used to move the battery box 30 in the vertical direction.

[0045] Figure 3 This is a structural schematic diagram of the frame 11 and the traveling mechanism 12. (See attached diagram.) Figure 2 and Figure 3As shown, the frame 11 is movable along a first direction to align with both sides of the battery storage area 40. In this embodiment, the frame 11 includes columns 113, a first connecting beam 111, and a second connecting beam 112. Multiple columns 113 extend vertically, with their tops horizontally connected to the first connecting beam 111 and the second connecting beam 112. The entire frame 11 is generally in a "gate" shape. The bottoms of the columns 113 on both sides are connected to the traveling mechanism 12. The traveling mechanism 12 is used to drive the frame 11 to move along the first direction. In this embodiment, the traveling mechanism 12 includes a traveling motor 121, multiple traveling wheels 124, and multiple sets of guide wheels 125. The traveling wheels 124 are rotatably connected to the bottom of the columns 113, and their rotating surfaces are located on tracks (not shown) on both sides of the battery storage area 40. The traveling motor 121 drives the traveling sprocket 123 to rotate via a traveling chain 122, and the traveling sprocket 123 drives the traveling wheels 124 to rotate, thereby moving the frame 11 along the first direction. Each set of guide wheels 125 includes at least one pair of guide wheels 125. The guide wheels 125 are rotatably connected to the column 113, and their rotating surfaces are clamped to both sides of the track to prevent the traveling wheels 124 from derailing, thereby improving the stability of the frame 11 during travel. In some other embodiments, the traveling mechanism 12 may also include a slider and a guide rail. The frame 11 is moved via a slider-guide rail structure, and a motor drives a sprocket to pull the frame 11 along the length of the tunnel via a chain.

[0046] Figure 4 This is a structural schematic diagram of the frame 11 and the cantilever beam 13. (See attached diagram.) Figure 2 and Figure 4 As shown, in this embodiment, the first connecting beam 111 and the second connecting beam 112 extend horizontally and are detachably connected to the column 113, for example, by riveting or connecting pieces. To adjust the height difference between the first connecting beam 111 and the second connecting beam 112 to adjust the angle between the cantilever beam 13 and the horizontal plane, at least one of the first connecting beam 111 and the second connecting beam 112 is connected to the column 113 by several shims to adjust the angle between the cantilever beam 13 and the horizontal plane. In this embodiment, both the first connecting beam 111 and the second connecting beam 112 are connected to the column 113 by one or more shims, achieving bidirectional adjustment of the angle of the cantilever beam 13. The structure of the first connecting beam 111 and the second connecting beam 112 connecting the cantilever beam 13 will be described in detail later and will not be repeated here.

[0047] One end of the cantilever beam 13 is connected to the frame 11, and its length direction is along the first direction ( Figure 1The cantilever beam 13 extends in the X direction shown, and its other end extends out of the frame 11 in the first direction. For ease of description, in this application, the end of the cantilever beam 13 near the frame 11 is referred to as the "inner end", and correspondingly, the end extending out of the frame 11 is referred to as the "outer end".

[0048] In this embodiment, in order to achieve the cantilever beam 13 and the gripping mechanism 14 in a second direction perpendicular to the first direction ( Figure 1 The cantilever beam 13 moves along the Y direction (shown in the diagram), and its inner end is movably connected to the frame 11. To balance the forces on the cantilever beam 13 and improve the stability of the battery swapping robot, in this embodiment, the cantilever beam 13 includes a first connection point and a second connection point located on both sides of the cantilever beam 13 along the vertical direction. The cantilever beam 13 is movably connected to the frame 11 at the first and second connection points along a second direction. For example, the first connection point is located above the inner end of the cantilever beam 13, and the second connection point is located between the first connection point and the outer end of the cantilever beam 13 and below the cantilever beam 13. That is, the first and second connection points are sequentially arranged along the direction from the inner end to the outer end of the cantilever beam 13. Thus, during operation, the frame 11 presses down on the cantilever beam 13 through the first connection point and supports the cantilever beam 13 at the second connection point, thereby improving the force distribution on the cantilever beam 13, increasing its supporting strength, and enhancing the load-bearing capacity of the battery swapping equipment 10. To achieve lateral movement of the cantilever beam 13, in this embodiment, the cantilever beam 13 is movably connected to a first connecting beam 111 at a first connection point along a second direction, and movably connected to a second connecting beam 112 at a second connection point along the second direction. The first connecting beam 111 is located above the rear end of the cantilever beam 13, and the second connecting beam 112 is located near the outer end of the cantilever beam 13 and below it. In some embodiments, the cantilever beam 13 can be movably connected to the frame 11 at the first and second connections using a slider-rail structure. However, those skilled in the art can also use other structures to movably connect the frame 11. The movable connection method and structure between the first and second connections and the frame 11 can be the same or different.

[0049] Figure 5 yes Figure 4 A magnified view of a portion of point A in the middle. (See image below.) Figure 4 and Figure 5As shown, to drive the cantilever beam 13 to move laterally in the second direction, the battery swapping robot may further include a lateral motor 15, a lateral gear 151, and a lateral rack 152. One of the lateral motor 15 and the lateral rack 152 is connected to the cantilever beam 13, and the other is connected to the frame 11. The lateral motor 15 engages with the lateral rack 152 via the lateral gear 151 to pull the cantilever beam 13 to move synchronously along the second direction at the first and second connection points. In this embodiment, the lateral motor 15 is mounted on the cantilever beam 13, and the lateral gear 151 is connected to the output shaft of the lateral motor 15. The lateral rack 152 extends generally along the second direction and connects to the second connecting beam 112. When it is necessary to drive the cantilever beam 13 to swing, the offset motor drives the offset gear to rotate, and the offset gear engages with the offset rack to drive the cantilever beam 13 to move laterally.

[0050] Figure 6 This is a structural schematic diagram of the cantilever beam 13 and the gripping mechanism 14. (See attached diagram.) Figure 6 As shown, the gripping mechanism 14 is connected to the outer end of the cantilever beam 13. The gripping mechanism 14 is used to dock with the battery box 30 and move the battery box 30 in a vertical direction. As an example, in this embodiment, the gripping mechanism 14 includes a gripping member 141, a moving seat 142, a support assembly, a drive assembly, a gripping motor 146, a drive wheel 147, and a traction rope 145. The gripping member 141 is used to dock with the battery box 30, the support assembly is used to guide and support the gripping member 141 to move vertically at the outer end of the cantilever beam 13, the drive assembly is used to drive the gripping member 141 to rotate relative to the moving seat 142, and the gripping motor 146, the drive wheel 147, and the traction rope 145 are used to pull the moving seat 142 to move vertically.

[0051] In this embodiment, the bottom of the gripper 141 may have one or more hooks to hook onto the battery box 30. Those skilled in the art will understand that, depending on the structure of the battery box 30, the gripper 141 may also have other structures to achieve engagement or disengagement with the battery box 30. The movable seat 142 is movably connected to the cantilever beam 13 in a vertical direction, and the gripper 141 is rotatably connected to the movable seat 142. In this embodiment, the movable seat 142 may be a frame-like structure, movably connected to the outer end of the cantilever beam 13 in a vertical direction. To improve the stability of the movable seat 142 and reduce the swaying amplitude during movement, in this embodiment, the movable seat 142 is movably connected to the cantilever beam 13 via a support assembly, which can guide the gripper 141 to move in a vertical direction. As an example, the support assembly includes a gripping guide rail 143 and a gripping slider 144. One of the gripping guide rail 143 and the gripping slider 144 is connected to the gripping member 141, and the other is connected to the cantilever beam 13. The gripping member 141 moves along the gripping guide rail 143 via the gripping slider 144. Specifically, in this embodiment, there is a pair of gripping guide rails 143, respectively disposed on both sides of the cantilever beam 13 along the second direction, and extending vertically to connect to the movable seat 142. Correspondingly, there are multiple gripping sliders 144, respectively connected to both sides of the cantilever beam 13. In this way, the movable seat 142 is movably connected to the cantilever beam 13 via the gripping guide rail 143 and the gripping slider 144. During the movement of the gripping member 141 in the vertical direction, the gripping guide rail 143 and the gripping slider 144 can guide and support the movable seat 142, preventing the gripping member 141 from swaying excessively during movement.

[0052] Figure 7 This is a schematic diagram of the gripping motor 146, drive wheel 147, and traction rope 145 of the gripping mechanism 14. Figure 7 As shown, the gripping motor 146 is mounted on the cantilever beam 13 and connected to the gripping member 141 via a traction rope 145, thereby pulling the gripping member 141 vertically upward or downward. Specifically, the gripping motor 146 is preferably positioned near the inner end of the cantilever beam 13, preferably directly above the frame 11. Multiple drive wheels 147 are rotatably connected to the cantilever beam 13. One end of the traction rope 145 is fixedly connected to the cantilever beam 13, extends upward, passes over one drive wheel 147, then extends downward, passes over another drive wheel 147, extends along the length of the cantilever beam 13 to its outer end, passes over another drive wheel 147, and extends downward to the connecting movable seat 142. The gripping motor 146 is connected to at least one drive wheel 147, thereby driving the traction rope 145 to move, and the traction rope 145 to move the movable seat 142 vertically.

[0053] Figure 8 This is a schematic diagram of the movable base 142, the gripping component 141, and the drive assembly in an disassembled state. Figure 8 As shown, the gripper 141 is rotatably connected to the movable seat 142. Specifically, the rotating member is rotatably connected to the movable seat 142 via a slewing bearing 148 at a position approximately at the geometric center, allowing the gripper 141 to rotate relative to the movable seat 142. A drive assembly connects the gripper 141 and the movable seat 142, and is used to drive the gripper 141 to rotate relative to the movable seat 142. As an example, the drive assembly includes a deflection motor 149, a deflection gear 1410, and a deflection rack 1411. One of the deflection motor 149 and the deflection rack 1411 is connected to the movable seat 142, and the other is connected to the gripper 141. The deflection motor 149 engages with the deflection rack 1411 via the deflection gear 1410, and is used to pull the gripper 141 to oscillate around the slewing bearing 148 as the rotation center. In this embodiment, the deflection motor 149 is mounted on the movable base 142, and the deflection gear 1410 is connected to the output shaft of the deflection motor 149. The deflection rack 1411 is generally an arc-shaped structure with the slewing bearing 148 as the center, and is connected to the side of the gripper 141 near the movable base 142. When it is necessary to drive the gripper 141 to swing, the deflection motor drives the deflection gear to rotate, and the deflection gear meshes with the deflection rack to drive the gripper 141 to rotate around the slewing bearing 148 as the center, thereby adjusting the angle of the gripper 141 relative to the battery box 30.

[0054] During operation, after vehicle 20 moves to the parking space along the second direction (Y direction), battery swapping equipment 10 moves along the first direction (X direction) across both sides of the battery storage area 40 to a position close to the end of vehicle 20. Then, gripping motor 146 drives moving base 142 and gripping member 141 to move vertically to the position corresponding to battery box 30 on vehicle 20. Simultaneously, deflection motor 149 drives gripping member 141 to swing until the angle of gripping member 141 corresponds to the position of battery box 30. Next, gripping member 141 hooks onto battery box 30, and gripping motor 146 drives battery box 30 to detach from vehicle 20. Then, walking mechanism 12 drives frame 11 to move along the first direction, and drives cantilever beam 13 to move laterally along the second direction via lateral movement motor 15, moving battery box 30 above battery seat 31 and placing battery box 30 on battery seat 31.

[0055] Then, the battery swapping device 10 drives the cantilever beam 13 to move laterally at the first connection and the second connection until the gripper 141 is above the other battery holder 31. The gripping mechanism 14 then grips the battery box 30 and moves the battery box 30 to the vehicle 20 to complete the battery swapping process.

[0056] The aforementioned front-mounted battery swapping device 10 and battery swapping station with deflection function connect the gripping mechanism 14 to the outer end of the cantilever beam 13. The gripping member 141 of the gripping mechanism 14 is rotatably connected to the outer end of the cantilever beam 13. When it is necessary to dock with the battery box 30, the gripping member 141 can rotate relative to the cantilever beam 13 at the outer end of the cantilever beam 13, thereby adjusting the angle of the gripping member 141 of the gripping mechanism 14 relative to the battery box 30, and completing the docking with the battery box 30 through the gripping mechanism 14.

[0057] Furthermore, the aforementioned front-mounted battery swapping equipment 10 with deflection function and the battery swapping station connect the gripping mechanism 14 to the cantilever beam 13. The cantilever beam 13 connects to the frame 11 at a first connection and a second connection, which are located on both sides of the cantilever beam 13 along the vertical direction. This balances the force on the cantilever beam 13 and improves its load-bearing capacity. Moreover, by adjusting the height difference between the first connecting beam 111 and the second connecting beam 112, the angle between the cantilever beam 13 and the horizontal plane can be adjusted.
