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:

[0006] The frame is movable along the first direction;

[0007] A cantilever beam includes a first connection point and a second connection point connecting the frame, and the outer end of the cantilever beam extends out of the frame along a first direction;

[0008] A gripping mechanism is connected to the outer end of a cantilever beam; the cantilever beam moves relative to the frame at a first connection point and a second connection point to adjust the angle of the cantilever beam so as to dock with the battery box via the gripping mechanism.

[0009] According to the aforementioned front-mounted battery swapping device with deflection function, the cantilever beam is rotatably connected to the frame at the first connection point and movably connected to the frame at the second connection point; or, the cantilever beam is movably connected to the frame at the first connection point and movably connected to the frame at the second connection point.

[0010] According to the aforementioned front-mounted battery swapping device with deflection function, the first connection point is located at the end away from the outer end, and the second connection point is located between the first connection point and the outer end.

[0011] According to the aforementioned front-mounted battery swapping device with deflection function, the second connection point is located at the end away from the outer end, and the first connection point is located between the second connection point and the outer end.

[0012] According to the aforementioned front-mounted battery swapping device with deflection function, the cantilever beam is connected to the frame at the first connection point via a slewing bearing.

[0013] According to the aforementioned front-mounted battery swapping device with deflection function, the cantilever beam is rotatably connected to the frame at the second connection point via rollers.

[0014] The front-mounted battery swapping device with deflection function further includes a deflection motor, a deflection gear, and a deflection rack. One of the deflection motor and the deflection rack is connected to the cantilever beam, and the other is connected to the frame. The deflection motor meshes with the deflection rack through the deflection gear to pull the cantilever beam to swing around the first connection point as the fulcrum.

[0015] The front-mounted battery swapping device with deflection function further includes a lateral movement mechanism, which includes a first lateral movement block and a second lateral movement block. The first lateral movement block and the second lateral movement block are movably connected to the frame along a second direction. The cantilever beam is rotatably connected to the first lateral movement block at the first connection point and movably connected to the second lateral movement block at the second connection point.

[0016] According to the aforementioned front-mounted battery swapping device with deflection function, the first lateral movement block and the second lateral movement block are respectively located on both sides of the cantilever beam along the vertical direction.

[0017] According to the aforementioned front-mounted battery swapping device with deflection function, the frame includes a column, a first connecting beam, and a second connecting beam. 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 first transverse block, and the second connecting beam is movably connected to the second transverse block.

[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 perpendicular to the first direction, and the length direction of the cantilever beam extends along the first direction.

[0020] In addition, this disclosure also provides a front-end battery swapping station, including:

[0021] The aforementioned front-mounted battery swapping device with deflection function;

[0023] A battery holder for storing a battery box is located on at least one side of the lane, and the front-mounted battery swapping device moves along the lane to exchange the battery box with the vehicle.

[0024] The aforementioned front-end battery swapping station also includes a parking space located at the end of the alleyway. The gripping mechanism of the front-end battery swapping equipment uses a cantilever beam to load the battery box onto the side of the frame in the direction of movement to transport the battery box.

[0025] Compared to existing technologies, the aforementioned front-mounted battery swapping equipment and battery swapping station with deflection function connects the gripping mechanism to a cantilever beam. The cantilever beam is connected to the frame at a first connection point and a second connection point. When it is necessary to dock with the battery box, the cantilever beam moves relative to the frame at the first connection point and the second connection point to adjust the angle of the cantilever beam. This allows the angle of the gripping mechanism relative to the battery box to be adjusted, and the battery box can be docked through the gripping mechanism. Attached Figure Description

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.

[0039] 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.

[0040] Figure 1 This is a structural diagram of a battery swapping station. (For example...) Figure 1 As shown, the front-end battery swapping station includes a front-end battery swapping device 10 with deflection function, an aisle, parking spaces, and battery holders. The battery holders are located in the area where the battery storage box 30 is located in the front-end battery swapping station. The aisle is located within this area, and the battery holders are located on at least one side of the aisle, for example, on one or both sides of the aisle in the width direction. Figure 1In the illustrated embodiment, battery holders are located on both sides of the aisle, with the aisle situated in the middle of the battery holders. The battery swapping device 10 is movably positioned within the aisle and can move back and forth along the length of the aisle. The parking space is located at the end of the aisle, and the front-mounted battery swapping device 10 loads the battery box 30 onto the side of the frame 11 in the direction of movement to transport the battery box 30.

[0041] When it is necessary to replace the battery box 30 of vehicle 20, vehicle 20 is parked at the parking space at the end of the alley along the direction of travel. The battery swapping equipment 10 is moved along the length of the alley to the end position near the parking space. The depleted battery box 30 is removed from vehicle 20 and moved along the length of the alley to a battery holder. The depleted battery box 30 is then moved to vehicle 20 along the length of the alley. The fully charged battery box 30 on another battery holder is moved to vehicle 20 to complete the battery swapping operation of vehicle 20.

[0042] 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, a traversing mechanism, 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.

[0043] Figure 3 This is a structural schematic diagram of the frame 11 and the traveling mechanism 12. (See attached diagram.) Figure 2 and Figure 3 As shown, the frame 11 is movable within the tunnel along a first direction (i.e., the length direction of the tunnel). In this embodiment, the frame 11 includes a column, a first connecting beam 111, and a second connecting beam 112. The column extends vertically, and the first connecting beam 111 and the second connecting beam 112 extend horizontally and are detachably connected to the column, 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 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 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.

[0044] like Figure 3As shown, the traveling mechanism 12 is connected to the frame 11 and is used to drive the frame 11 to move along the first direction. In this embodiment, the traveling mechanism 12 includes multiple traveling wheels 121 and multiple sets of guide wheels 122. The traveling wheels 121 are rotatably connected to the bottom of the column, and their rotating surfaces are set on the track located in the tunnel. The traveling wheels 121 are driven by a motor to rotate and pull the frame 11 to move along the length direction of the tunnel. Each set of guide wheels 122 includes at least one pair of guide wheels 122. The guide wheels 122 are rotatably connected to the column, and their rotating surfaces are clamped on both sides of the track to prevent the traveling wheels 121 from leaving the track, thereby improving the stability of the frame 11's movement. In other embodiments, the traveling mechanism 12 may also include a slider and a guide rail. The frame 11 is moved through a slider-guide rail structure, and the sprocket driven by a motor moves the frame 11 along the length direction of the tunnel around a chain.

[0045] Figure 4 This is a structural schematic diagram of the frame 11, the traversing mechanism, and the cantilever beam 13. (See attached diagram.) Figure 2 and Figure 4 As shown, one end of the cantilever beam 13 is connected to the frame 11, and its length direction is along the first direction ( Figure 1 The 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".

[0046] Specifically, the cantilever beam 13 includes a first connection point 131 and a second connection point 132 connecting the frame 11. The cantilever beam 13 can move relative to the frame 11 at the positions of the first connection point 131 and the second connection point 132, and can rotate or translate relative to the frame 11. The cantilever beam 13 moves relative to the frame 11 at the first connection point 131 and the second connection point 132 to adjust the angle of the cantilever beam 13, thereby accurately docking with the battery box 30 through the gripping mechanism 14. In some embodiments, the cantilever beam 13 is rotatably connected to the frame 11 at the first connection point 131 and movably connected to the frame 11 at the second connection point 132; in other embodiments, the cantilever beam 13 is movably connected to the frame 11 at the first connection point 131 and movably connected to the frame 11 at the second connection point 132. Furthermore, this application does not limit the positions of the first connection point 131 and the second connection point 132. In some embodiments, the first connection point 131 is located at the inner end away from the outer end, and the second connection point 132 is located between the first connection point 131 and the outer end, that is, in the direction from the inner end to the outer end, the first connection point 131 and the second connection point 132 are sequentially arranged. In other embodiments, the second connection point 132 is located at the end away from the outer end, and the first connection point 131 is located between the second connection point 132 and the outer end, that is, in the direction from the inner end to the outer end, the second connection point 132 and the first connection point 131 are sequentially arranged.

[0047] Figure 5 This is a structural schematic diagram of cantilever beam 13. As an example, in... Figure 4 and Figure 5 In the illustrated embodiment, the first connection point 131 is located near the inner end of the cantilever beam 13, which is connected to the frame 11 via a slewing bearing 152. This allows the cantilever beam 13 to rotate horizontally relative to the frame 11 at the first connection point 131. The second connection point 132 is located near the outer end of the cantilever beam 13, and is tactilely connected to the frame 11 via rollers 153. This allows the cantilever beam 13 to move relative to the frame 11 at the second connection point 132 via the rollers 153, ultimately swinging the cantilever beam 13 with the first connection point 131 as the rotation center and the second connection point 132 as the radius. This allows adjustment of the angle of the gripping mechanism 14 to facilitate docking of the gripping mechanism 14 with the battery box 30.

[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 1The cantilever beam 13 moves along the Y direction (shown in the diagram) and is connected to the frame 11 via a lateral movement mechanism. The lateral movement mechanism includes a first lateral block 15 and a second lateral block 151. The first lateral block 15 and the second lateral block 151 are movably connected to the frame 11 along a second direction. The cantilever beam 13 is rotatably connected to the first lateral block 15 at the first connection point 131 and movably connected to the second lateral block 151 at the second connection point 132. For example, the first lateral block 15 and the second lateral block 151 can be movably connected using a slider-rail structure, but those skilled in the art can also use other structures to achieve the movable connection. The movable connection method between the first lateral block 15 and the second lateral block 151 and the frame 11 can be the same or different. Furthermore, the first lateral block 15 and the second lateral block 151 are located on opposite sides of the cantilever beam 13 along the vertical direction. The first connecting beam 111 movably connects to the first lateral block 15, and the second connecting beam 112 movably connects to the second lateral block 151. In this embodiment, as an example, the first lateral moving block 15 is located above the rear end of the cantilever beam 13, and the second lateral moving block 151 is located near the outer end of the cantilever beam 13 and below it. The first lateral moving block 15 presses down on the cantilever beam 13, and the second lateral moving block 151 supports the cantilever beam 13, thereby increasing the supporting force of the cantilever beam 13 and improving the load-bearing capacity of the power swapping equipment 10. Specifically, the cantilever beam 13 is connected upwards to the first lateral moving block 15 via a slewing bearing 152 at the first connection point 131, realizing a rotatable connection between the frame 11 at the first connection point 131 and the slewing bearing 152 and the first lateral moving block 15. Furthermore, the lower side of the cantilever beam 13 is provided with a connecting groove 133 at the second connection point 132. The connecting groove 133 is generally arc-shaped and extends in the horizontal plane; correspondingly, there can be one or more rollers 153, rotatably connected to the second lateral moving block 151. The roller 153 is embedded in the connecting groove 133, with its rotating surface facing the connecting groove 133. In this way, the cantilever beam 13 can roll within the connecting groove 133 via the roller 153 and be translatably connected to the frame 11 via the second transverse block 151. Simultaneously, as mentioned earlier, since the vertical direction of the cantilever beam 13 is connected to the first connecting beam 111 and the second connecting beam 112 via the first transverse block 15 and the second transverse block 151 respectively, the angle between the cantilever beam 13 and the horizontal plane can be easily adjusted by adjusting the height difference between the first connecting beam 111 and the second connecting beam 112. Thus, the cantilever beam 13 can be laterally moved along the Y direction and connected to the frame 11 via the first transverse block 15 and the second transverse block 151. In some embodiments, the lateral movement mechanism may further include a lateral movement motor 157, which can drive at least one of the first lateral movement block 15 and the second lateral movement block 151 to move via a gear-rack structure or a sprocket-chain structure, thereby realizing the synchronous lateral movement of the first lateral movement block 15 and the second lateral movement block 151 along the Y direction.

[0049] Figure 6 yes Figure 4 A magnified view of a portion of point A in the image. (See image below.) Figure 4 and Figure 6 As shown, to drive the cantilever beam 13 to swing, the lateral movement mechanism also includes a deflection motor 154, a deflection gear 156, and a deflection rack 155. One of the deflection motor 154 and the deflection rack 155 is connected to the cantilever beam 13, and the other is connected to the frame 11. The deflection motor 154 meshes with the deflection rack 155 through the deflection gear 156, and is used to pull the cantilever beam 13 to swing around the first connection point 131 as the rotation center. In this embodiment, the deflection motor 154 is mounted on the cantilever beam 13, and the deflection gear 156 is connected to the output shaft of the deflection motor 154. The deflection rack 155 is generally an arc-shaped structure with the first connection point 131 as the center, and is connected to the second lateral movement block 151. When it is necessary to drive the cantilever beam 13 to swing, the offset motor drives the offset gear to rotate. The offset gear meshes with the offset rack and drives the cantilever beam 13 to rotate around the first connection point 131 as the center of rotation. The cantilever beam 13 moves on the second transverse block 151 through the roller 153 at the second connection point 132, thereby realizing the function of swinging the cantilever beam 13.

[0050] Figure 7 This is a structural schematic diagram of the cantilever beam 13 and the gripping mechanism 14. (See attached diagram.) Figure 7 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 the vertical direction. As an example, in this embodiment, the gripping mechanism 14 includes a gripping member 141, a gripping chain 142, and a gripping motor 143. The gripping member 141 is used to dock with the components of the battery box 30. In this embodiment, the bottom of the gripping member 141 has one or more components to hook the battery box 30. The gripping motor 143 is mounted on the cantilever beam 13 and is connected to the gripping member 141 through the gripping chain 142, thereby pulling the gripping member 141 to rise or fall in the vertical direction through the gripping chain 142.

[0051] 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) within the aisle to a position near the end of the aisle close to vehicle 20. Then, gripping motor 143 drives gripping member 141 to move vertically to the position corresponding to battery box 30 on vehicle 20. Simultaneously, deflection motor 154 drives cantilever beam 13 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 143 drives battery box 30 to detach from vehicle 20. Then, traveling mechanism 12 drives frame 11 to move along the length of the aisle, and lateral movement motor 157 drives at least one of first lateral movement block 15 and second lateral movement block 151 to move laterally along the Y direction, moving battery box 30 above the battery holder and placing battery box 30 on the battery holder.

[0052] Then, the battery swapping device 10 drives the first lateral block 15 and the second lateral block 151 to move laterally in sync until the gripper 141 is above another battery holder. The gripper mechanism 14 then grips the battery box 30 and moves the battery box 30 to the vehicle 20 to complete the battery swapping process.

[0053] The aforementioned front-mounted battery swapping device 10 with deflection function and battery swapping station connect the gripping mechanism 14 to the cantilever beam 13. The cantilever beam 13 is connected to the frame 11 at the first connection point 131 and the second connection point 132. When docking with the battery box 30 is required, the cantilever beam 13 rotates or translates relative to the frame 11 at the first connection point 131 and the second connection point 132 to adjust the angle of the cantilever beam 13, thereby adjusting the angle of the gripping mechanism 14 relative to the battery box 30, and docking with the battery box 30 is achieved through the gripping mechanism 14. In addition, the cantilever beam 13 is connected to the first connecting beam 111 through the first lateral block 15 and to the second connecting beam 112 through the second lateral block 151. In this way, 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.
