[0023] The chassis assembly and transport device provided in this application embodiment have a housing disposed above the chassis body, forming a receiving cavity with the chassis body. A battery can be placed inside the receiving cavity, corresponding to an opening on the housing, allowing for battery replacement through the opening. Simultaneously, a first side of the battery cover is rotatably connected to the housing, and a second side of the battery cover is detachably connected to the housing. Thus, when battery replacement is not required, the second side of the battery cover can be connected to the housing, allowing the battery cover to cover the opening on the housing, preventing external debris from entering the receiving cavity through the opening, thereby protecting the battery and other structures within the receiving cavity. When battery replacement is required, the second side of the battery cover can be separated from the housing, and the first side of the battery cover can be rotated relative to the housing, thereby lifting the battery cover relative to the opening on the housing to expose the opening, allowing for battery replacement. It can be seen that compared to the process of removing the entire housing and replacing the battery, the chassis assembly provided in this application embodiment only requires disassembling one side of the battery cover, simplifying the disassembly and installation work required during battery replacement. Meanwhile, the opening for battery replacement is located on the outer casing, that is, above the chassis assembly. Compared to a structure where the battery needs to be replaced under the chassis body, it eliminates the need to flip the chassis assembly, making it easier to operate. Attached Figure Description

[0037] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the protection scope of this application.
[0038] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0039] Furthermore, in this application, directional terms such as "upper," "lower," "inner," and "outer" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.
[0040] With the popularization of intelligence, transportation devices (such as handling robots) can be widely used in various fields, such as warehousing and logistics, manufacturing, and service industries.
[0041] In the field of warehousing and logistics, transport devices can automatically travel to the goods storage area (such as shelves) according to the instructions of the warehouse management system, and move designated items from the storage area to designated areas (such as sorting or shipping areas). The handling efficiency of transport devices is higher than that of manual handling, thereby shortening the turnaround time of goods and improving the space utilization of the warehousing system.
[0042] The transport device moves within the warehousing system using the driving force provided by a mobile chassis, which is typically derived from a battery installed on the chassis. During operation, the battery provides power to the chassis, driving the drive wheels and thus moving the chassis.
[0043] When the battery is low, the mobile chassis will not function properly. In this case, the transport device can be stopped and moved to the charging area by the mobile chassis to charge the battery. Once the battery is fully charged, the transport device will operate normally. Because the mobile chassis cannot leave the charging area while the battery is charging, the transport device cannot operate, resulting in reduced transport efficiency and impacting the handling efficiency and space utilization of the warehousing system.
[0044] To reduce the impact of charging on the working efficiency of the transport device, the battery of the mobile chassis with insufficient power can be replaced with a fully charged battery. Since the time required to replace the battery is less than the time required to charge the battery, the working efficiency of the transport device can be improved.
[0045] However, replacing the battery often requires removing the entire casing of the mobile chassis to expose the battery, then removing the battery, installing a fully charged battery, and finally reinstalling the entire casing of the mobile chassis. This process takes a considerable amount of time, at least 30 minutes. Although shorter than the charging time, it still impacts the efficiency of the transport device.
[0046] To address the aforementioned issues, this application provides a chassis assembly and a transportation device that can improve battery replacement efficiency, reduce the impact of battery replacement on work efficiency, thereby improving the work efficiency of the chassis assembly and transportation device, and enhancing the handling efficiency and space utilization of the warehousing system.
[0047] Figure 1 This is a schematic diagram of the overall structure of a chassis component provided in an embodiment of this application;
[0048] Figure 2 This is a partial structural diagram of a chassis assembly with the battery cover omitted, provided in an embodiment of this application.
[0049] like Figure 1 and Figure 2 As shown, the chassis assembly 1 provided in this application embodiment includes a chassis body 11, a shell 12, a battery 13, and a battery cover 14.
[0050] For ease of explanation, the following description uses the length direction of chassis component 1 as the x-axis, the width direction as the y-axis, and the height direction as the z-axis. Specifically, the length direction of battery 13 corresponds to the width direction of chassis component 1, the width direction of battery 13 corresponds to the length direction of chassis component 1, and the height direction of battery 13 corresponds to the height direction of chassis component 1.
[0051] It should be noted that in other examples, the length and width directions of the battery 13 may be the same as those of the chassis assembly 1, depending on the placement direction of the battery 13 on the chassis body 11. In this embodiment, the placement direction of the battery 13 is not limited.
[0052] The outer shell 12 is fastened to the top of the chassis body 11 and forms a receiving cavity 10 with the chassis body 11.
[0053] For example, in order to ensure a stable connection between the chassis body 11 and the outer shell 12, the outer shell 12 can be fixedly connected to the chassis body 11 by bolts to prevent the outer shell 12 from shaking relative to the chassis body 11, thereby preventing other structures (such as loading devices, gantry, and loading structures) located above the outer shell 12 from shaking relative to the chassis body 11 and affecting the stable operation of the transport device.
[0054] The battery 13 is disposed in the receiving cavity 10, which serves to house and protect the battery 13. The outer casing 12 has an opening a corresponding to the location of the battery 13. This allows the battery 13 to enter or leave the receiving cavity 10 through the opening a. When replacing the battery 13, it is not necessary to disassemble the outer casing 12, effectively reducing the complexity of battery replacement.
[0055] The battery cover 14 includes a first side 14a and a second side 14b. The first side 14a is movably connected to the outer casing 12, meaning it can rotate relative to the outer casing 12. The second side 14b is detachably connected to the outer casing 12, meaning it can be connected to or not connected to the outer casing 12. Thus, when the battery 13 does not need to be replaced, the second side 14b of the battery cover 14 can be connected to the outer casing 12, covering the opening a to prevent sand, dust, sewage, and other debris from the external environment from entering the receiving cavity 10 through the opening a, thus affecting the safety of the battery 13 and the stable operation of the chassis assembly 1. When the battery 13 needs to be replaced, the second side 14b of the battery cover 14 can be separated from the outer casing 12, allowing the first side 14a of the battery cover 14 to rotate relative to the outer casing 12, thereby exposing the opening a for battery replacement.
[0056] In one example, the battery 13 needs to be replaced when its charge level is less than or equal to a set value. The set value for the battery 13's charge level could be 10% of full charge, 5% of full charge, etc.
[0057] In another example, battery 13 may need to be replaced when it needs to be inspected or maintained, or when other structures in the chassis assembly 1 need to be inspected. It is understood that the reason for replacing battery 13 can be adjusted according to the actual situation, and is not limited in this embodiment.
[0058] The chassis assembly 1 provided in this application embodiment has a housing 12 disposed above the chassis body 11, forming a receiving cavity 10 together with the chassis body 11. A battery 13 can be disposed within the receiving cavity 10, corresponding to an opening a on the housing 12, allowing the battery 13 to be replaced through the opening a. Simultaneously, a first side 14a of a battery cover 14 is rotatably connected to the housing, and a second side 14b of the battery cover 14 is detachably connected to the housing 12. Thus, when the battery 13 does not need to be replaced, the second side 14b of the battery cover 14 can be connected to the housing 12, allowing the battery cover 14 to cover the opening a on the housing 12, thereby preventing external debris from entering the receiving cavity 10 through the opening a. This protects the battery 13 and other structures within the receiving cavity 10, and also prevents the first side 14a of the battery cover 14 from detaching from the housing 12 and shaking during normal operation of the chassis assembly 1. When battery 13 needs to be replaced, the second side 14b of battery cover 14 can be separated from housing 12, allowing the first side 14a of battery cover 14 to rotate relative to housing 12. This lifts the opening a of battery cover 14 relative to housing 12, exposing the opening a, and allowing battery 13 to be replaced. It can be seen that compared to the process of removing the entire housing and replacing battery 13, the chassis assembly 1 provided in this embodiment only requires disassembling one side of battery cover 14, simplifying the removal and installation work required during battery 13 replacement. Furthermore, by placing the opening a for battery 13 replacement on housing 12, i.e., above chassis assembly 1, compared to the structure requiring battery 13 replacement below chassis body 11, the chassis assembly 1 does not need to be flipped, facilitating operation.
[0059] Furthermore, in the embodiment of this application, the method of replacing the battery 13 by disassembling one side of the battery cover 14 takes approximately 1-5 minutes to complete the entire battery replacement process. Compared to the method of removing the entire casing, this effectively reduces the battery replacement time, thereby improving the working efficiency of the chassis assembly 1 and the transport device. Simultaneously, since the warehousing system often contains multiple transport devices, reducing the battery replacement time for each transport device by half an hour saves a significant amount of time compared to the entire warehousing system, thus improving the working efficiency and space utilization of the warehousing system.
[0060] For example, the second side 14b can be the side opposite to the first side 14a, or the side adjacent to the first side 14a, or the second side 14b can be any side other than the first side 14a. In this embodiment, no limitation is made, and the example of the second side 14b being the side opposite to the first side 14a is used for illustration.
[0061] Figure 3 This is a schematic diagram of the structure of a battery cover and a first connector provided in an embodiment of this application.
[0062] Figure 4 It is the outer casing, battery cover and first connector along Figure 1 A schematic diagram of the cross-sectional structure along the AA direction.
[0063] Combination Figure 3 and Figure 4 As shown, exemplarily, the chassis assembly 1 also includes a first connector 15, through which the second side 14b of the battery cover 14 can be detachably connected to the housing 12.
[0064] Specifically, either the second side 14b of the battery cover 14 or the outer casing 12 is provided with a mounting groove b, and the other side is provided with a mounting hole c corresponding to the mounting groove b.
[0065] In one example, the second side 14b of the battery cover 14 is provided with a mounting groove b, and the outer casing 12 is provided with a mounting hole c corresponding to the mounting groove b. In this case, the first connector 15 can be disposed in the mounting groove b and can be detachably connected to the mounting hole c, thereby realizing the detachable connection between the second side 14b of the battery cover 14 and the outer casing 12.
[0066] In another example, the outer casing 12 is provided with a mounting groove b, and the second side 14b of the battery cover 14 is provided with a mounting hole c corresponding to the mounting groove b. In this case, the first connector 15 can be disposed in the mounting groove b and can be detachably connected to the mounting hole c, thereby realizing the detachable connection between the second side 14b of the battery cover 14 and the outer casing 12.
[0067] Meanwhile, the first connector 15, located in the mounting slot b, is lower than the top surface of the housing 12 and / or the battery cover 14 along the height direction of the battery 13. In other words, along the height direction of the battery 13, the top surface of the first connector 15 can be lower than either the housing 12 or the battery cover 14, or both. This ensures that the first connector 15 does not protrude from the housing 12 or the battery cover 14, thereby avoiding any impact on the design of other structures on the top surface of the housing 12 and the battery cover 14, and also avoiding any impact on the detection functions of sensors such as radar mounted on the chassis assembly 1.
[0068] For example, the first connector 15 may include a first pin, which includes a first body portion 151 and a first insertion portion 152.
[0069] The first main body 151 can be connected to the mounting slot b, and the first insert 152 is movably connected to the first main body 151. Thus, when the battery 13 does not need to be replaced, the first insert 152 can be inserted into the mounting hole c to maintain the connection between the second side 14b of the battery cover 14 and the outer casing 12. When the battery 13 needs to be replaced, the first insert 152 can move relative to the first main body 151 and separate from the mounting hole c, thereby disconnecting the second side 14b of the battery cover 14 from the outer casing 12, allowing the second side 14b of the battery cover 14 to leave the outer casing 12. In other words, the battery cover 14, relative to the outer casing 12, can be considered a "door" for replacing the battery 13, and the first insert can be considered a "latch." When the battery 13 does not need to be replaced, the "door" can be locked using the "latch," and when the battery 13 needs to be replaced, the "latch" can be opened to open the "door," facilitating the replacement of the battery 13.
[0070] It should be noted that in other examples, the first connector 15 can also be a bolt. When the battery 13 does not need to be replaced, the bolt can be connected to the mounting hole c to maintain the connection between the second side 14b of the battery cover 14 and the housing 12. When the battery 13 needs to be replaced, the bolt can be disengaged from the mounting hole c, thereby disconnecting the second side 14b of the battery cover 14 from the housing 12, allowing the second side 14b of the battery cover 14 to leave the housing 12. Compared to bolts, the connection and disengagement of the first pin are simpler, further improving disassembly efficiency.
[0071] Optionally, the first pin can be a push-button pin. Push-button pins are simple to operate, occupy little space, and are easy to switch between locked and unlocked states, resulting in high disassembly efficiency.
[0072] Alternatively, the first pin can also be a sliding pin or a rotating pin, which is not limited in this embodiment.
[0073] For example, either the first side 14a of the battery cover 14 or the outer casing 12 is provided with a snap-fit portion d, and the other side is provided with a snap-fit hole e corresponding to the snap-fit portion d. In this case, when the battery does not need to be replaced, the battery cover 14 can be connected to the outer casing 12 through the snap-fit connection between the snap-fit portion d and the snap-fit hole e. When the battery 13 needs to be replaced, the battery cover 14 can rotate relative to the outer casing 12 through the relative rotation of the snap-fit portion d and the snap-fit hole e, and separate from the outer casing 12 when the snap-fit portion d and the snap-fit hole e are separated. Thus, when replacing the battery 13, the battery cover 14 can be removed from the outer casing 12, thereby avoiding any interference with the operator's work during the battery replacement process.
[0074] For example, the snap-fit portion d can be a snap-fit plate, snap-fit post, etc. extending toward the snap-fit hole e, and is not limited in this embodiment.
[0075] Optionally, there may be one or more snap-fit parts d, and multiple snap-fit parts d may be set at intervals. In this embodiment, there is no restriction on the setting of snap-fit parts d.
[0076] In one example, the first side 14a of the battery cover 14 is provided with a snap-fit portion d, and the outer casing 12 is provided with a snap-fit hole e corresponding to the snap-fit portion d.
[0077] In another example, the housing 12 is provided with a snap-fit portion d, and the first side 14a of the battery cover 14 is provided with a snap-fit hole e corresponding to the snap-fit portion d.
[0078] It should be noted that in other examples, the first side 14a of the battery cover 14 and the outer casing 12 can also be connected by a hinge, thereby enabling a rotatable connection between the battery cover 14 and the outer casing 12. Alternatively, the first side 14a of the battery cover 14 and the outer casing 12 can also be connected by a pivot. In this embodiment, the rotatable connection between the first side 14a of the battery cover 14 and the outer casing 12 is not limited.
[0079] For example, the housing 12 includes a housing body 121 and a support member 122.
[0080] The outer casing 121 can be connected to the chassis body 11, forming a receiving cavity 10. An opening a is provided on the outer casing 121. A support member 122 is connected to the outer casing 121 and extends towards the chassis body 11 to close the receiving cavity 10 where the battery 13 is located. Thus, when the opening a of the outer casing 121 is large, the outer casing 121 has poor rigidity at the opening a position and is prone to deformation. In this case, the support member 122 can support the outer casing 121 and also separate the receiving cavity 10 where the battery 13 is located, thereby protecting both the outer casing 121 and the battery 13.
[0081] Specifically, the support member 122 is provided with a snap-fit hole e on the side facing the battery 13, and the battery cover 14 is provided with a snap-fit part d. The snap-fit part d can be rotatably snapped into the snap-fit hole e, thereby realizing the rotatable connection of the battery cover 14 relative to the outer shell 12.
[0082] For example, the separate arrangement of the outer shell 121 and the support member 122 also allows for the selection of different materials for the outer shell 121 and the support member 122. The outer shell 121 can be made of plastic. Since the outer shell 121 covers a large area, using plastic can help reduce the weight of the entire chassis assembly 1. Meanwhile, the support member 122 can be made of metal, which effectively ensures the structural strength of the support member 122 to achieve stable support for the outer shell 121.
[0083] Figure 5This is a structural schematic diagram of a support member provided in an embodiment of this application.
[0084] Combination Figure 4 and Figure 5 As shown, specifically, the support member 122 may include a connecting part 1221 and a supporting part 1222.
[0085] The connecting part 1221 can be connected to the surface of the outer shell body 121 facing the receiving cavity 10. The supporting part 1222 is connected to the connecting part 1221 and the chassis body 11, and extends along the outer shell body 121 toward the chassis body 11. In this way, the outer shell body 121 and the supporting part 122 can be connected through the inner surface, thereby avoiding the impact on the outer surface of the outer shell body 121, so that the outer surface of the outer shell body 121 can form a complete and continuous surface, which facilitates the installation of other structures, especially avoiding the impact on the installation of the gantry, the carrying device and the picking mechanism installed above the chassis assembly 1 in the transport device.
[0086] For example, the connecting portion 1221 can be bent relative to the supporting portion 1222. The connecting portion 1221 may include multiple connecting plates for connection with the outer shell body 121. The multiple connecting plates may be disposed on opposite sides of the supporting portion 1222, and multiple connecting plates may also be disposed on the same side of the supporting portion 1222. It is understood that the arrangement of the connecting plates can be adjusted according to the shape of the outer shell body 121, and is not limited in this embodiment.
[0087] Optionally, in order to facilitate the connection between the connecting part 1221 and the inner surface of the outer shell body 121, the connecting part 1221 and the outer shell body 121 can be connected by adhesive bonding.
[0088] Alternatively, the connecting part 1221 and the outer shell body 121 can also be connected by snap-fit, etc., which is not limited in this embodiment.
[0089] Furthermore, the support portion 1222 may include a support plate and support ribs to improve the structural strength of the support portion 1222 and prevent deformation. It should be noted that the specific configuration of the support portion 1222 can be selected according to actual conditions and is not limited in this embodiment.
[0090] It is understood that in other examples, the outer shell 121 and the support 122 may also be an integral structure, and this embodiment is not limited to this.
[0091] For example, the outer casing 121 also has an overlapping portion 121a recessed into the receiving cavity 10 at the opening a corresponding to the battery cover 14. This allows the battery cover 14 to overlap with the overlapping portion 121a, preventing it from falling into the receiving cavity 10 and impacting the battery 13. Simultaneously, the recessed overlapping portion 121a ensures that the top surface of the battery cover 14 is on the same plane as the top surface of the outer casing 12, thus preventing the surface of the battery cover 14 from being too high and affecting the arrangement of other structures on the surface of the battery cover 14 and the outer casing 121, and also preventing any impact on the functional settings of sensors such as radar on the chassis assembly 1.
[0092] Optionally, the overlapping portion 121a may be recessed into the receiving cavity 10 from the edge of the outer shell body 121 and bent to form a folded edge for overlapping the battery cover 14.
[0093] Alternatively, the overlapping portion 121a can be a bent plate connected to the outer casing body 121 and extending into the receiving cavity 10, so as to overlap the battery cover 14 using the bent plate.
[0094] Optionally, the overlapping portion 121a may be continuously provided along the edge of the outer shell body 121.
[0095] Alternatively, the overlapping portion 121a may be provided at intervals along the edge of the outer shell body 121.
[0096] Optionally, the overlapping portion 121a may correspond to the remaining side of the battery cover 14 other than the first side 14a, or the overlapping portion 121a may correspond to the second side 14b of the battery cover 14.
[0097] It should be noted that the specific arrangement of the overlapping part 121a is not limited in this embodiment.
[0098] Please refer to it again. Figure 3 For example, the battery cover 14 includes a battery cover body 141 and a handle 142. The battery cover body 141 may include a first side 14a and a second side 14b, and may overlap with the overlapping portion 121a. The handle 142 may be disposed on the battery cover body 141 and recessed toward the receiving cavity 10. In this way, the first side 14a of the battery cover 14 can be rotated relative to the support member 122 by means of the handle 142. At the same time, the recessed arrangement of the handle 142 can also avoid affecting the arrangement of other structures on the surface of the battery cover 14 and the arrangement of sensors such as radar.
[0099] For example, there may be two handles 142, which may be spaced apart to facilitate lifting the first side 14a of the battery cover body 141.
[0100] It should be noted that the handle 142 can be a pull ring, pull plate, etc. embedded on the surface of the battery cover body 141. In this embodiment, the specific structure of the handle 142 is not limited, and the number of handles 142 and their position on the battery cover body 141 are not limited in this application embodiment.
[0101] Figure 6 This is a structural schematic diagram of the battery, battery bracket, and pressure-bearing component provided in the embodiments of this application.
[0102] like Figure 6 As shown, exemplarily, the chassis assembly 1 also includes a pressure-bearing member 16. The pressure-bearing member 16 is disposed within the receiving cavity 10 and connected to the chassis body 11. Along the height direction of the battery 13, the top surface of the pressure-bearing member 16 is higher than the top surface of the battery 13. Thus, when foreign objects fall onto the surface of the battery cover 14 or the surface of the outer casing 121, the pressure-bearing member 16 can preferentially absorb the impact of the falling foreign object, preventing the external impact from directly acting on the battery 13, thereby protecting the battery 13. Furthermore, the provision of the pressure-bearing member 16 can also improve the supporting strength of the structure disposed on the surface of the battery cover 14, preventing the battery cover 14 from being deformed by pressure and affecting the safe operation of the battery 13.
[0103] For example, the pressure-bearing member 16 can be a support column, support platform, or support plate, etc., that can support the battery cover 14.
[0104] There can be one or more pressure-bearing components 16. When there is one pressure-bearing component 16, the length of the pressure-bearing component 16 can be less than the length of the battery 13, or it can be equal to or greater than the length of the battery 13.
[0105] When there are multiple pressure-bearing components 16, the multiple pressure-bearing components 16 can be spaced out on one side of the battery 13, or they can be spaced out on multiple sides of the battery 13. In this embodiment, the specific arrangement of the pressure-bearing components 16 is not limited.
[0106] Figure 7 yes Figure 6 A schematic diagram of its decomposed structure.
[0107] Figure 8 It is along Figure 6 Cross-sectional view along the BB direction.
[0108] Combination Figure 2 , Figure 6 , Figure 7 as well as Figure 8As shown, exemplarily, the chassis assembly 1 also includes a battery bracket 17. The battery bracket 17 is located within the receiving cavity 10, connected to the chassis body 11, and positioned corresponding to the opening a on the outer casing body 121. The battery 13 includes a battery body 131 and a connecting ear 132, the connecting ear 132 being connected to the battery body 131. The battery body 131 is disposed within the battery bracket 17, and the connecting ear 132 is detachably connected to the battery bracket 17, thereby allowing the battery 13 to be detachably connected relative to the battery bracket 17 for easy replacement.
[0109] For example, the battery holder 17 may include a base plate 171, a first side plate 172, a second side plate 173, and a second connector 174.
[0110] The base plate 171 is connected to the chassis body 11. A first side plate 172 is connected to the base plate 171 and extends along the length of the battery body 131, located on both sides of the battery 131 along its width, thus limiting the battery body 131 along its width. A second side plate 173 is connected to the base plate 171 and extends along the width of the battery body 131, located on both sides of the battery 131 along its length, thus limiting the battery body 131 along its length. A second connector 174 is disposed on either the first side plate 172 or the second side plate 173 and is detachably connected to the connecting ear 132. Thus, the connecting ear 132 can be detachably connected to the battery bracket 17 via the second connector 174, facilitating the removal of the battery 13. Furthermore, the second connector 174 also limits the battery body 131 along its height.
[0111] Optionally, the first side plate 172 and the second side plate 173 can be connected to each other.
[0112] Alternatively, the first side plate 172 and the second side plate 173 can be arranged alternately.
[0113] Optionally, the first side plate 172 and / or the second side plate 173 can both be rectangular plates.
[0114] Alternatively, the first side plate 172 and / or the second side plate 173 may also be triangular plates. It is understood that the shapes of the first side plate 172 and the second side plate 173 may be the same or different, and this is not limited in this embodiment. Furthermore, the shapes of multiple first side plates 172 may be the same or different. The shapes of multiple second side plates 173 may be the same or different, and this is not limited in this embodiment.
[0115] It should be noted that the specific positions and shapes of the first side plate 172 and the second side plate 173 can be adjusted according to actual conditions, and are not limited in this embodiment.
[0116] For example, the connecting ear 132 may include a first connecting plate 1321. The first connecting plate 1321 is arranged parallel to the base plate 171 and is connected to the side of the battery body 131. Along the height direction of the battery 13, the first connecting plate 1321 is located on the side of the second connector 174 near the base plate 171, that is, the second connector 174 is located above the first connecting plate 1321.
[0117] It should be noted that, due to the influence of the processing and manufacturing process, the parallel arrangement of the first connecting plate 1321 and the base plate 171 can be approximately parallel, but in this embodiment, it is limited to a completely parallel arrangement.
[0118] For example, the second connector 174 includes a second pin, which includes a second main body portion 1741 and a second insertion rod portion 1742. The second main body portion 1741 can be connected to the first side plate 172, and the second insertion rod portion 1742 is movably connected to the second main body portion 1741. Thus, when the battery 13 does not need to be replaced, the second insertion rod portion 1742 can be engaged with the first connecting plate 1321 to restrict the movement of the battery 13 in the height direction and maintain the connection between the battery 13 and the battery holder 17; when the battery 13 needs to be replaced, the second insertion rod portion 1742 can be separated from the first connecting plate 1321, allowing the battery 13 to move in the height direction, thereby facilitating the removal and replacement of the battery 13.
[0119] It should be noted that in other examples, the second connector 174 can also be a bolt. When the battery 13 does not need to be replaced, the bolt can connect the first connecting plate 1321 to the first side plate 172 to restrict the movement of the battery 13 in the height direction and maintain the connection between the battery 13 and the battery holder 17. When the battery 13 needs to be replaced, the bolt can separate the first connecting plate 1321 from the first side plate 172, allowing the battery 13 to move in the height direction, thus facilitating the removal and replacement of the battery 13. Compared to bolts, the connection and separation operation of the second pin is simpler and can further improve the disassembly efficiency.
[0120] Optionally, there can be one or more second pins. When there are multiple second pins, they can be arranged on both sides of the battery body 131 along the width direction or on both sides along the length direction. Multiple second pins located on the same side of the battery body 131 can be spaced apart.
[0121] In this example, there can be two second pins. The two second pins can be located on both sides of the battery body 131 along the width direction and along the length direction of the battery body 131. In other words, the two second pins can be set near the two diagonal positions of the battery body 131, so as to achieve a stable connection to the battery 13 and effectively save the number of second pins, so as to facilitate disassembly and improve disassembly efficiency.
[0122] Optionally, the second pin can be a push-button pin. Push-button pins are simple to operate, occupy little space, and are easy to switch between locked and unlocked states, resulting in high disassembly efficiency.
[0123] Alternatively, the second pin can also be a sliding pin or a rotating pin, which is not limited in this embodiment.
[0124] For example, the connecting ear 132 may further include a second connecting plate 1322 and a third connecting plate 1323. The second connecting plate 1322 is connected to the side of the battery body 131, and the first connecting plate 1321 is connected to the second connecting plate 1322. The third connecting plate 1323 is connected to the second connecting plate 1322 and is disposed opposite to the first connecting plate 1321. The third connecting plate 1323 is detachably connected to the base plate 171. In this way, during transportation, the chassis assembly 1 can connect the third connecting plate 1323 to the base plate 171 to improve the connection stability between the battery body 131 and the battery bracket 17, preventing the battery 13 from moving or detaching from the chassis body 11 during transportation. During the operation of chassis assembly 1, the third connecting plate 1323 can be disconnected from the base plate 171. Thus, when replacing the battery 13, only the second connecting piece 174 needs to be adjusted, without needing to adjust the connection between the third connecting plate 1323 and the base plate 171. This can effectively improve the disassembly efficiency of the battery 13, thereby improving the replacement efficiency of the battery 13.
[0125] Optionally, the third connecting plate 1323 and the base plate 171 can be connected by bolts. During the transportation of the chassis assembly 1, the third connecting plate 1323 and the base plate 171 can be connected by bolts. During the operation of the chassis assembly 1, the bolts can be removed.
[0126] For example, the battery holder 17 also includes a guide plate 175. The guide plate 175 is connected to the first side plate 172. The guide plate 175 can be inclined, and along the width direction of the battery 13, the distance between the top surfaces of two opposing guide plates 175 is greater than the width of the battery 13. In this way, when the battery 13 is installed in the battery holder 17, the guide plate 175 can be used for guidance to avoid collision between the first side plate 172 and the battery 13, and the installation efficiency of the battery 13 can also be improved.
[0127] Alternatively, the guide plate 175 can be a straight plate that is tilted.
[0128] Alternatively, the guide plate 175 can be a curved plate. It is understood that as long as the guide plate 175 is tilted or bent along the side opposite to the battery 13, the specific shape of the guide plate 175 is not limited in this embodiment.
[0129] For example, the battery bracket 17 also includes a base 176. The base 176 can be connected to the chassis body 11, and the base plate 171 is connected to the base 176, with a gap H between the chassis and the chassis body 11. In this way, the battery 13 mounted on the base plate 171 can improve its heat dissipation speed through the gap H. At the same time, the gap H can also prevent external impacts on the chassis body from directly acting on the base plate 171 and being transmitted to the bottom surface of the battery 13, thereby buffering external impacts and achieving heat dissipation protection and structural protection for the battery 13, thus ensuring the safe and stable operation of the battery 13.
[0130] Optionally, the base 176 may include four square tubes connected end to end, so that a hollow area can be formed in the center of the base 176 to facilitate the spacing between the base plate 171 and the chassis body 11.
[0131] Alternatively, the base 176 may include a connecting plate with a hollow structure and a support plate extending along the height direction of the battery 13, so as to connect the connecting plate to the base plate 171 and use the support plate to achieve the spacing between the base plate 171 and the chassis body 11.
[0132] It is understood that the specific configuration of the base 176 can be determined according to the actual situation, and this application embodiment does not impose any restrictions.

[0134] like Figure 9 As shown, in a second aspect, embodiments of this application also provide a transportation device 100, including a chassis assembly 1, the chassis assembly 1 having a bearing surface 1a, the bearing surface 1a being capable of bearing goods.
[0135] Optionally, the goods can be placed directly on the bearing surface 1a. Alternatively, when there are many goods, they can be placed on a mobile shelf, and the bearing surface 1a of the chassis assembly 1 can support the mobile shelf to support and fix the goods, preventing the goods from falling off the bearing surface 1a during movement.
[0136] Alternatively, a gantry frame 2 can be installed on the bearing surface 1a of the transport device 100. A lifting mechanism can be slidably installed on the gantry frame 2, and a picking mechanism 3 can be installed on the lifting mechanism. In this way, the transport device 100 can pick up, place, and transport goods at different height positions.
[0137] It should be noted that the transport device 100 may also include other structures, which are not limited in this embodiment.
