Technical Field

[0001] This utility model relates to the field of battery pack transportation technology, and more specifically, to a battery pack transportation device and a battery swapping station. Background Technology

[0002] During the construction and commissioning of heavy-duty truck battery swapping stations, it is necessary to locate the coordinates of the battery gripping component and accurately align the battery pack gripped by the component with the battery placement position on the battery rack.

[0003] Traditional positioning methods involve using a gantry crane to lift the battery pack. First, a mobile device is used to move the battery pack above the battery rack. Then, the gripping component of the mobile device lowers the battery pack, aligning it with the battery rack. This process is repeated until the battery pack is fully aligned and in contact with the rack, obtaining the position coordinates of the gripping component. These coordinates are then recorded by the control system for subsequent automatic gripping and placement of the battery pack. This method is not only time-consuming and labor-intensive, but also requires the battery pack to be brought to the site for commissioning simultaneously, resulting in a long overall commissioning cycle and delaying the commissioning time of the battery swapping station. Utility Model Content

[0004] The problem this invention addresses is: how to improve the efficiency of coordinate positioning and debugging of the battery grabbing component in a battery swapping station.

[0005] To address the aforementioned problems, this utility model provides a battery pack transportation device and a battery swapping station.

[0006] In a first aspect, this utility model provides a battery pack transport device, comprising: track; A mobile device is slidably connected to the track, the mobile device including a gripping component for gripping a battery pack; A battery rack carrier, located below the track, is used to support the battery pack; The alignment device includes multiple positioning parts and multiple plumb bob components.

[0007] Optionally, the battery pack transport device further includes a detachable connection, through which the plumb bob component and the gripping component are detachably connected.

[0008] Optionally, the plumb bob component includes a plumb bob, a suspension line, and a bolt, with the two ends of the suspension line connected to the plumb bob and the bolt, respectively; wherein the bolt is threaded into the detachable connection part so that the bolt can move vertically relative to the detachable connection part.

[0009] Optionally, the bolt is provided with a first through hole, which extends through the bolt along the axial direction of the bolt, and the suspension line passes through the first through hole from the end face of the bolt near the ground and extends and is fixed to the end face of the bolt away from the ground.

[0010] Optionally, the contact portion between the gripping component and the detachable connection includes a ferromagnetic portion, and the detachable connection is a switch-type magnetic base.

[0011] Optionally, the surface of the gripping component near the ground is provided with multiple grooves, and the multiple grooves are inserted into the multiple detachable connecting parts one by one.

[0012] Optionally, a positioning mark is provided on the end face of the positioning part away from the ground.

[0013] Optionally, the positioning part has a recess on the end face away from the ground.

[0014] Optionally, the positioning part includes a first part and a second part arranged sequentially from bottom to top. The first part is a cylinder, and the second part is a frustum or a cone.

[0023] In related technologies, during the construction and commissioning of heavy-duty truck battery swapping stations, it is necessary to locate the coordinates of the battery gripping component to precisely align the battery pack on the gripping component with the battery placement position on the battery rack. The traditional positioning method involves using a gantry crane to lift the battery. First, a mobile device is used to move the battery pack above the battery rack. Then, the gripping component of the mobile device lowers the battery pack, physically aligning it with the placement position on the battery rack. This process is continuously adjusted until the battery pack is fully contacted and aligned, thus obtaining the position coordinates of the gripping component. These coordinates are then recorded by the control system for subsequent automatic gripping and placement of the battery pack. This method is not only time-consuming and labor-intensive but also requires the battery pack to be brought to the site for commissioning simultaneously, resulting in a long overall commissioning cycle and delaying the commissioning time of the battery swapping station.

[0024] To address the problems existing in the aforementioned related technologies, this utility model provides a battery pack transportation device 10 and a battery swapping station 100, combined with... Figures 1 to 5As shown, this embodiment provides a battery pack transport device 10, including a track 21, a moving device 22, a battery rack carrier 30, and an alignment device 40. The moving device 22 is slidably connected to the track 21, and the moving device 22 includes a gripping component 23 for gripping the battery pack. The battery rack carrier 30 is located below the track 21 and is used to carry the battery pack. The alignment device 40 includes multiple positioning parts 50 and multiple plumb bob components 60. The positioning parts 50 are located on the upper surface of the battery rack carrier 30, and the plumb bob components 60 are located on the lower surface of the gripping component 23. The multiple plumb bob components 60 are used to correspond one-to-one with the multiple positioning parts 50 and be aligned vertically to align the gripping component 23 with the battery rack carrier 30. Using the moving device 22 slidably connected to the track 21, the gripping component 23 is moved above the battery rack carrier 30, so that the gripping component 23 is roughly aligned with the battery rack carrier 30. The gripping component 23 is then lowered. With the aid of the alignment device 40 and the correspondence between the positioning part 50 and the plumb bob part 60, the plumb bob part 60 hangs down naturally under gravity, forming a vertical reference line. The positioning part 50 serves as a fixed reference point on the battery rack carrier 30. The combination of the two can visually reflect the positional deviation between the gripping component 23 and the battery rack carrier 30. Based on the alignment deviation between the plumb bob and the positioning part 50, the position of the moving device 22 is further finely adjusted so that the gripping component 23 is precisely aligned with the battery rack carrier 30. This facilitates the precise alignment of the gripping component 23 and the battery rack carrier 30. The coordinates of the precise alignment are the coordinates of the battery pack compartment of the gripping component 23 on the track 21. This eliminates the need for repeated adjustments based on the actual battery pack, shortens the debugging time, improves the debugging efficiency of the coordinate positioning of the battery gripping component 23 in the battery swapping station 100, and accelerates the commissioning process of the battery swapping station 100.

[0025] Specifically, the battery pack transport device 10 also includes a drive component for driving the moving device 22 to slide along the track 21. The drive component is electrically connected to the control system and can precisely control the moving distance and speed of the moving device 22 according to the instructions of the control system, so as to achieve accurate positioning of the gripping component 23 on the track 21. At the same time, the drive component can also drive the gripping component 23 to move up and down and horizontally to adapt to the battery pack gripping needs at different heights and positions. The specific structure of the drive component is not the focus of this application. As long as it can realize the sliding of the moving device 22 and the lifting and translation of the gripping component 23, it is acceptable. No specific limitation is made here.

[0026] In some embodiments, please refer to the following for details. Figure 2 The battery pack transport device 10 also includes a detachable connection part 70, through which the plumb bob component 60 and the gripping component 23 are detachably connected.

[0027] The detachable nature of the detachable connection 70 facilitates the disassembly of the plumb bob component 60 after commissioning, preventing the plumb bob component 60 from interfering with the gripping operation of the gripping component 23 on the battery pack during normal equipment operation. The detachable design also facilitates the replacement and maintenance of the plumb bob component 60. When the plumb bob component 60 experiences wear or malfunction, it can be quickly replaced without extensive disassembly of the gripping component 23, reducing maintenance and time costs and enhancing the flexibility and lifespan of the equipment.

[0028] Specifically, the design of the detachable part 70 adopts a snap-on connection structure or a bolt 63 connection structure, which facilitates quick installation and disassembly while ensuring the stability of the connection.

[0029] In some embodiments, please refer to the following for details. Figure 2 The plumb bob component 60 includes a plumb bob 61, a suspension line 62, and a bolt 63. The two ends of the suspension line 62 are connected to the plumb bob 61 and the bolt 63, respectively. The bolt 63 is threaded into the detachable part 70, allowing the bolt 63 to move vertically relative to the detachable connection part 70. By rotating the bolt 63, the overall height of the plumb bob component 60 can be finely adjusted vertically, enabling the plumb bob 61 to more accurately align with the positioning part 50, reducing the distance between the plumb bob 61 and the positioning part 50, improving the accuracy of visual alignment, further enhancing the flexibility and precision of alignment, and avoiding alignment errors caused by the fixed length of the suspension line 62.

[0030] In some embodiments, please refer to the following for details. Figure 3 The bolt 63 has a first through hole 64, which extends through the bolt 63 axially. The suspension line 62 passes through the first through hole 64 from the end face of the bolt 63 near the ground and extends and is fixed to the end face of the bolt 63 away from the ground. The first through hole 64 constrains and guides the suspension line 62, preventing it from deviating from the vertical direction due to swaying, tangling, or external interference during descent. This ensures the stability and reliability of the baseline formed by the plumb bob component 60, improving accuracy during multiple alignments or repeated adjustments.

[0031] Specifically, the suspension line 62 can be extended and fixed to the end face of the bolt 63 away from the ground by tying a knot at the end of the suspension line 62 or by using fasteners to lock it in place, so as to prevent the suspension line 62 from slipping or loosening during use. The specific fixing method can be selected according to actual needs. This is just an example and is not a specific limitation.

[0032] In some embodiments, please refer to the following for details. Figure 3The contact portion between the gripping component 23 and the detachable connecting part 70 includes a ferromagnetic portion, and the detachable connecting part 70 is a switch-type magnetic base. By controlling the presence or absence of magnetism in the switch-type magnetic base via a switch, rapid adsorption and separation between the detachable connecting part 70 and the gripping component 23 are achieved. The installation and disassembly process requires no complex tools, significantly improving the efficiency of assembling and disassembling the plumb bob component 60 during the debugging phase, saving debugging time. The adsorption connection method does not damage the surface of the gripping component 23, ensuring the structural integrity and service life of the gripping component 23. Generally, the main body of the gripping component 23 is a steel structure, which itself has a certain magnetic attraction property; that is, the ferromagnetic portion is a steel structure. When used in conjunction with the switch-type magnetic base, it can achieve rapid positioning and fixation, and leaves no residue or traces during disassembly.

[0033] In some embodiments, please refer to the following for details. Figure 3 The gripping component 23 has multiple grooves 24 on its surface near the ground, and each groove 24 corresponds to one of the detachable connecting parts 70. The grooves 24 provide installation positions for the detachable connecting parts 70, ensuring that the installation position of each plumb bob component 60 on the gripping component 23 is fixed, guaranteeing the relative positional accuracy between the multiple plumb bob components 60, and thus improving the overall accuracy when aligned with the corresponding positioning part 50. The grooves 24 also limit the detachable connecting parts 70, preventing them from shifting due to shaking of the moving device 22 or external impact during the debugging process, enhancing the stability of the alignment process, and making it easier for operators to quickly find the installation position, thus improving the convenience of the debugging operation.

[0034] In some embodiments, the positioning part 50 may be a guide pin of the battery rack carrier 30 for the battery pack. The guide pin is set at a predetermined position of the battery rack carrier 30 and is used to cooperate with the positioning hole on the battery pack to achieve a guiding function, ensuring that the battery pack moves along a preset trajectory during installation and reducing assembly resistance or damage risk caused by deviation.

[0035] In some embodiments, please refer to the following for details. Figure 4 The positioning part 50 has a positioning mark 51 on the end face away from the ground. The positioning mark 51, such as a crosshair or a center point mark, can clearly indicate the reference position of the positioning part 50. The operator can quickly determine the direction and magnitude of the alignment deviation between the gripping part 23 and the battery rack carrier 30 by observing the relative position of the tip of the plumb bob component 60, such as the plumb bob 61, and the positioning mark 51. This reduces subjective judgment errors and improves the efficiency and accuracy of alignment adjustment.

[0036] In some embodiments, please refer to the following for details. Figure 5The positioning part 50 has a recess 52 on the end face away from the ground. The recess 52 can serve as a precise alignment target for the plumb bob component 60. For example, the tip of the plumb bob 61 can naturally fall into the recess 52, forming a physical alignment fit. Compared with planar markings, it can more accurately reflect the alignment status, reduce judgment errors caused by visual errors, and improve the efficiency and accuracy of alignment adjustment.

[0037] In some embodiments, please refer to the following for details. Figure 4 , Figure 5 The positioning part 50 includes a first part 501 and a second part 502 arranged sequentially from bottom to top. The first part 501 is a cylinder, and the second part 502 is a frustum or cone. The two ends of the first part 501 are respectively connected to the battery rack carrier 30 and the second part 502. Specifically, the contact surfaces of the first part 501 and the second part 502 coincide. The first part 501 is a cylinder, and the second part 502 is a frustum or cone. The cylindrical structure of the first part 501 has good mechanical stability and can be firmly connected to the battery rack carrier 30, providing solid support for the entire positioning part 50. The top of the frustum or cone structure of the second part 502 is provided with a gradually narrowing small plane or tip, which can serve as a high-precision alignment reference point. The plumb bob component 60 can more easily achieve precise alignment with this small plane or tip, which can significantly improve the alignment accuracy compared to a single cylindrical structure.

[0038] For details, please refer to [link / reference]. Figure 4 , Figure 5 The first part 501 and the second part 502 are integrally formed, that is, manufactured by integral molding process, to ensure the connection strength and coaxiality between the two, thereby improving the rigidity and stability of the overall structure, and further ensuring the durability and alignment accuracy of the positioning part 50 during use.

[0039] Combination Figure 6 This embodiment also provides a battery swapping station 100, including any of the battery pack transport devices 10 described above. The specific structure of the battery pack transport device 10 can be found in the battery pack transport device 10 and corresponding accessories described in the foregoing embodiments. Figures 1 to 5 The specific location of the battery pack transport equipment 10 and its arrangement in the battery swapping station 100 can be flexibly adjusted according to the actual working conditions, and will not be elaborated here.

[0040] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
