[0034] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0035] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "higher," "lower," "top," and "bottom" generally refer to the orientation of the corresponding component or structure in the direction of gravity. "Inner" and "outer" refer to the inner and outer contours of the corresponding component. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0036] For ease of understanding, please refer to the appendix below. Figures 1 to 9 The specific structure and working principle of the battery swapping device for the automated delivery vehicle disclosed herein will be described in detail with reference to the embodiments.

[0037] This disclosure relates to a battery swapping system for an automated delivery vehicle, which effectively utilizes the space within the battery casing 1 to install a battery management component 3, avoiding the battery management component 3 occupying a large portion of the battery casing 1, thereby reducing the overall size of the battery swapping system. See also Figure 1 , Figure 2 and Figure 9The battery for the automated delivery vehicle disclosed herein includes a housing 1, a cell assembly 2, and a battery management assembly 3. The housing 1 has multiple sidewalls 11 arranged along a first direction, which can be enclosed to form an opening for accommodating the cell assembly 2. The number of sidewalls 11 can be determined according to the actual battery shape. For example, when the housing 1 is rectangular, there are four sidewalls 11 arranged perpendicularly to each other to form a rectangular housing 1. The cell assembly 2 is accommodated in the accommodating space formed by the housing 1 and serves as the main power supply for the battery, including multiple cells 21 arranged side by side along the first direction. The battery management component 3 is installed between either side wall 11 of the cell assembly 2 and the housing 1. For example, the battery management component 3 can be located on the side wall 11 opposite to the cell assembly 2 to ensure that the battery management component 3 will not collide with the cell assembly 2 when the battery is shaken. Alternatively, it can be located on the side wall 11 where the cell assembly 2 is located, thereby reducing the height of the battery and allowing the battery to adapt to more different usage needs. Furthermore, depending on the type and size of the battery management component 3, a suitable position between the side wall 11 and the cell assembly 2 can be selected for installation. The specific location can be determined according to the actual situation, and will not be elaborated further here.

[0038] The battery swapping system of the automated delivery vehicle disclosed herein can make full use of the space between the side wall 11 and the cell assembly 2 in the housing 1 by installing the battery management component 3 between the cell assembly 2 and any side wall of the housing 1. This improves the utilization efficiency of space resources in the housing 1, thereby eliminating the need to set up a connection part in the housing 1 that requires a large space for the installation of the battery management component 3. This reduces the overall volume of the battery swapping system and facilitates the replacement and maintenance of the battery during use.

[0039] Optionally, see Figure 3 and Figure 4The battery swapping device disclosed herein also includes a fixing member 4, which is used to fix the battery management component 3. The fixing member 4 can be plate-shaped or other shapes that can adapt to the battery management component 3 to facilitate the installation of the battery management component 3. A mounting part 5 is provided on the side wall 11 of the housing 1. The mounting part 5 can be integrally formed with the side wall 11 of the housing 1 or can be installed separately later. The fixing member 4 can be connected to the side wall 11 of the housing 1 through the mounting part 5. The fixing member 4 and the mounting part 5 are detachably connected together, which facilitates the removal of the fixing member 4. When the battery management component 3 fails, the fixing member 4 can be removed from the mounting part 5 for repair, avoiding the need to replace the entire battery swapping device housing 1 due to the failure of the battery management component 3. Thus, the position of the battery management component 3 connected to the fixing member 4 can be installed between the cell assembly 2 and the side wall 11 where the mounting part 5 is located, so as to make full use of the space between the side wall 11 and the cell assembly 2 in the housing 1 and improve the utilization efficiency of space resources in the housing 1.

[0040] Optionally, see Figure 3 and Figure 5 The mounting part 5 is an integrally formed mounting boss 51 on the side wall 11 of the housing 1. The mounting boss 51 protrudes from the side wall 11 of the housing 1, making it easier for workers to locate the mounting boss 51 and for the fastener 4 to cooperate with the mounting boss 51 to complete the installation. The fastener 4 can cooperate with the mounting boss 51 to be fixedly connected to the mounting boss 51, so as to connect the battery management component 3 to the side wall 11 of the housing 1 and the cell assembly 2. Of course, in other embodiments, the mounting part 5 can also be of other structures, such as a groove provided on the side wall 11 of the housing 1, etc., depending on the actual situation, and this disclosure does not limit it.

[0041] Optionally, the mounting boss 51 and the end opening of the housing 1 are axially spaced and built in to prevent the fastener 4 connected to the mounting boss 51 from protruding outside the housing 1 after installation, making installation difficult. During installation, the fastener 4 can be mounted on the axial end face of the mounting boss 51 and extend along the side wall 11 with a gap from the side wall 11, so that the fastener 4 has sufficient length and space to install the battery management assembly 3.

[0042] In this embodiment, a first mounting hole 511 is also provided on the axial end face of the mounting boss 51. The fastener 4 can be detachably connected to the mounting boss 51 through the first mounting hole 511. For example, the first mounting hole 511 is a threaded hole. When it is necessary to connect the fastener 4 to the mounting boss 51, it can be connected by bolts. When disassembling, the bolts can be removed, making disassembly and assembly convenient. Of course, in other embodiments, the detachable connection between the fastener 4 and the mounting boss 51 can also be other connection methods known to those skilled in the art, which will not be described in detail here.

[0043] Optionally, see Figure 4 and Figure 6 The mounting boss 51 is formed as a strip-shaped boss extending along the axial direction of the housing 1. By setting the mounting boss 51 as a strip-shaped boss, it can strengthen the side wall 11 of the housing 1 to a certain extent. In order to further strengthen the strength of the housing 1, a strip-shaped reinforcing rib 111 can also be integrally formed at the corner of the side wall 11 of the housing 1. The strip-shaped reinforcing rib 111 extends from one end of the housing 1 to the other end. By setting the strip-shaped reinforcing rib 111, the corner of the housing 1 can be strengthened. A second mounting hole 112 is also provided on the strip-shaped reinforcing rib 111. The end cover 6 of the housing 1 can be easily connected to the housing 1 through the second mounting hole 112. The connection method can also be the connection through threaded holes and bolts, which will not be described in detail here.

[0044] Optionally, the strip-shaped boss can be integrally formed with the strip-shaped reinforcing rib 111, and the axial end face of the strip-shaped boss is spaced apart from the axial end face of the strip-shaped reinforcing rib 111 along the axial direction. The strip-shaped boss and the strip-shaped reinforcing rib 111 can each have rounded corners. Integrating the strip-shaped boss and the strip-shaped reinforcing rib 111 can enhance the strength of the strip-shaped boss and help the strip-shaped reinforcing rib 111 further enhance the strength at the corner of the housing 1. The spaced arrangement of the axial end face of the strip-shaped boss and the axial end face of the strip-shaped reinforcing rib 111 can prevent the fastener 4 connected to the strip-shaped boss from protruding outside the housing 1 and making it difficult to install. The rounded corners on the strip-shaped boss and the strip-shaped reinforcing rib 111 facilitate processing and improve the processing efficiency of the housing 1. On the other hand, the rounded corners can also prevent the strip-shaped boss and the strip-shaped reinforcing rib 111 from damaging components such as the cell assembly 2 and the battery management assembly 3.

[0045] In one embodiment of this disclosure, see Figure 4 and Figure 6At least two mounting bosses 51 are provided and spaced apart along the side wall 11. By providing at least two mounting bosses 51, the stability of the connection between the fixing member 4 and the mounting bosses 51 can be enhanced. For example, two mounting bosses 51 can be provided, and the interval between the two mounting bosses 51 can be the same as the length of the fixing member 4 along the extension direction of the side wall 11, so that both ends of the fixing member 4 can be supported by the mounting bosses 51, thereby improving the stability of the connection between the fixing member 4 and the side wall 11 of the housing 1, and preventing the fixing member 4 from falling off the side wall 11 during the use of the battery swapping, which could cause the battery management component 3 and the cell component 2 to collide and be damaged.

[0046] Optionally, the housing 1 has a square cross-section, with four strip-shaped reinforcing ribs 111 located at the four corners of the housing 1, and two strip-shaped bosses located at two adjacent corners of the square housing 1. The square housing 1 is easy to process and is a conventional shape for battery housings. The strip-shaped reinforcing ribs 111 at the corners can enhance the strength of the corners of the housing 1, while the strip-shaped bosses can ensure the stability of the connection between the fixing member 4 and the housing 1, and also assist the strip-shaped reinforcing ribs 111 in enhancing the strength of the corners of the housing 1. Of course, in other embodiments, the housing 1 and the mounting part 5 can also have other structures, depending on the actual situation, and this disclosure does not impose any limitations on this.

[0047] Optionally, the housing 1 has a square cross-section, and four strip-shaped mounting protrusions 51 can be provided, located at the four corners of the housing 1 respectively. On the one hand, this can further strengthen the strength of the corners of the housing 1. On the other hand, two adjacent strip-shaped protrusions can be used to install the fixing member 4 to complete the installation of the battery management component 3, so that the battery management component 3 is located in front of the side wall 11 and the cell assembly 2, thereby improving the utilization rate of the space in the housing 1. The other two adjacent strip-shaped protrusions can be used to fix the cell assembly 2 to ensure the stability of the cell assembly 2 during use.

[0048] Optionally, see Figure 4 and Figure 6The housing 1 has a mounting surface 12 that conforms to the battery tray. The side wall 11 where the battery management component 3 is located is opposite to the side wall 11 forming the mounting surface 12. Since the side wall 11 forming the mounting surface 12 is usually in direct contact with the cell assembly 2, it serves to support and place the cell assembly 2, and is also the side that contacts the battery tray in the automated delivery vehicle when the battery is being used. The fact that the side wall 11 where the battery management component 3 is located is opposite to the side wall 11 forming the mounting surface 12 allows the battery management component 3 to be located on top of the cell assembly 2. Compared to the battery management component 3 being located on the side wall of the cell assembly 2, when the battery is shaken due to external factors during use, the cell assembly 2 will inevitably shake slightly with the battery. If the battery management component 3 is located on the side wall of the cell assembly 2, it is easily damaged by the pressure of the shaking cell assembly 2. The above situation will not occur if it is located on top of the cell assembly 2, thus ensuring the safety and stability of the battery management component 3 during the use of the battery.

[0049] Optionally, the side wall 11 where the mounting part 5 is located is configured to be spaced apart from the side wall 11 forming the mounting surface 12. With this configuration, the distance between the battery management component 3 and the cell assembly 2 can be controlled by controlling the size of the distance between the mounting part 5 and the side wall 11, ensuring that the battery management component 3 does not come into contact with the cell assembly 2, thereby avoiding damage to the battery management component 3 during battery use.

[0050] In one embodiment of this disclosure, see Figure 3 and Figure 7 The fixing member 4 includes a fixing plate 41, which is arranged parallel to the side wall 11 where the mounting part 5 is located. The parallel arrangement between the fixing plate 41 and the side wall 11 allows the fixing plate 41 to form a flat plate when installing the battery management component 3, so as to facilitate the installation of the battery management component 3. Of course, in other embodiments, the fixing member 4 can also have other structures, such as a shape corresponding to the battery management component 3 or a shape corresponding to the side wall 11 of the housing 1. Specifically, it can be determined according to the relative position and shape between the battery housing 1, the cell assembly 2 and the battery management component 3, as long as it can be ensured that the battery management component 3 can be located between the side wall 11 and the cell assembly 2 after being installed on the fixing member 4.

[0051] Optionally, a reinforcing rib 411 is provided on the side of the fixing plate 41 near the side wall 11. By providing the reinforcing rib 411, the strength of the fixing plate 41 can be enhanced, and the fixing plate 41 can be damaged when installing the battery management component 3. The reinforcing rib 411 can be a strip-shaped protrusion arranged longitudinally and transversely on the surface of the fixing plate 41, or other reinforcing structures. The other side of the fixing plate 41 away from the side wall 11 is used to install the battery management component 3. Furthermore, to ensure that the reinforcing ribs 411 on the side of the fixing plate 41 do not come into contact with the side wall 11 and thus interfere, and to ensure the safety of the battery management component 3, when the fixing plate 41 is connected to the mounting part 5, the mounting part 5 is configured to ensure that there is a gap between the fixing plate 41 and the side wall 11 on which the mounting part 5 is provided, and between the battery management component 3 and the cell assembly 2. The gap between the fixing plate 41 and the side wall 11 on which the mounting part 5 is provided can accommodate the reinforcing ribs 411, thus avoiding interference between the reinforcing ribs 411 and the side wall 11. The gap between the battery management component 3 and the cell assembly 2 can ensure that the battery management component 3 will not collide with the cell assembly 2 when the battery is shaken or moved in other ways during battery swapping.

[0052] Optionally, see Figure 5 , Figure 7 and Figure 8 A first fixing boss 412 is formed on the side of the fixing plate 41 near the side wall 11 where the mounting part 5 is provided, and a second fixing boss 413 is formed on the side for mounting the battery management component 3. The first fixing boss 412 protrudes from the side of the fixing plate 41 and a first fixing hole 414 extending axially along the mounting part 5 is formed on the first fixing boss 412. The first fixing hole 414 is coaxially arranged with the first mounting hole 511 on the mounting part 5. The fixing can be completed through the first fixing hole 414, the first mounting hole 511 and the first connector 44. The detachable connection between the fixed plate 41 and the mounting part 5 can be, for example, the first fixed boss 412 can be a cylindrical boss, the first fixed hole 414 and the first mounting hole 511 are threaded holes, and the first connector 44 is a bolt. When connecting, it is only necessary to screw the bolt into the two coaxially set threaded holes. When disassembling, it is only necessary to remove the bolt. The whole disassembly and assembly process is relatively convenient. The first fixed boss 412 protrudes from the side of the fixed plate 41 and can also ensure that there is a gap between the fixed plate 41 and the side wall 11 that can accommodate the reinforcing rib 411.

[0053] The second fixing boss 413 is provided with a second fixing hole 415 perpendicular to the side of the fixing plate 41. The battery management component 3 can be connected to the fixing plate 41 through the second fixing hole 415 and the second connector 45. For example, the second fixing hole 415 can also be a threaded hole. The battery management component 3 is provided with a threaded hole coaxial with the second fixing hole 415, and then the two can be fixedly connected by bolts. Of course, in other embodiments, the fixing member 4 can also be other structures. For example, it can be installed by snap-fit ​​or by adhesive. As long as it can be fixed to the mounting part 5 and the battery management component 3 can be installed, it is acceptable. The specific design can be determined according to the actual situation, and this disclosure does not limit it.

[0054] In one embodiment of this disclosure, see Figure 5 and Figure 6 The fastener 4 has a first fixing part 42 and a second fixing part 43 spaced apart along the axial direction of the housing 1. The first fixing part 42 can be detachably connected to the mounting part 5 via a third connector 46. In some embodiments, the first fixing boss 412 and the first connector 44 are the first fixing part 42 and the third connector 46. In other embodiments, the first fixing part 42 and the third connector 46 can also be other structures that are set separately, as long as the detachable connection between the fastener 4 and the mounting part 5 can be completed.

[0055] A fixing adhesive 47 is provided between the second fixing part 43 and the side wall 11 where the mounting part 5 is provided. The fixing adhesive 47 can fix the second fixing part 43 to the side wall 11. By providing the first fixing part 42 and the second fixing part 43 along the axial direction of the housing 1, the fixing part 4 can be fixedly connected to the side wall 11 at both ends along the axial direction of the housing 1. This can further enhance the strength and stability of the connection between the fixing part 4 and the side wall 11, thereby preventing the fixing part 4 from falling off the side wall 11 during battery use and causing damage to the battery management component 3.

[0056] In one embodiment of this disclosure, see Figure 1 and Figure 9The battery swapping device disclosed herein also includes an end cap 6, which can close the open end of the housing 1 to seal the opening. Optionally, an integrated electrical connection device 7 is provided on the end cap 6. The integrated electrical connection device 7 is located on the side of the end cap 6 away from the mounting surface 12. The mounting part 5 and the fixing member 4 are also located on the side wall 11 of the housing 1 opposite to the side wall 11 forming the mounting surface 12, that is, on the side away from the mounting surface 12. The integrated electrical connection device 7 is used to connect with the high-voltage circuit and the low-voltage circuit in the housing 1, that is, the battery management component 3, so that the external circuit can be connected to the high-voltage circuit and the low-voltage circuit in the battery through the integrated electrical connection device 7. By setting the integrated electrical connection device 7, the mounting part 5, and the fixing member 4 on the same side, it is convenient to connect the integrated electrical connection device 7 to the low-voltage line in the battery management component 3 on the fixing member 4, which can reduce the connection distance between the two, thereby further saving space in the battery swapping housing 1 and improving space utilization.

[0057] When installing the battery management component 3 of the battery swapping device of the automated delivery vehicle disclosed herein, the connection between the fixing plate 41 and the mounting boss 51 is first required. The installation process is as follows: align the first fixing hole 414 on the first fixing boss 412 with the first mounting hole 511 on the mounting boss 51, and then complete the installation of both using the first connector 44. After that, the battery management component 3 can be installed with the fixing plate 41. The installation process is as follows: align the second fixing hole 415 on the second fixing part 43 with the connecting part on the battery management component 3, and then complete the installation of both using the second connector 45. During the connection process, the CAN communication harness and power supply harness in the battery management component 3 can also be connected to the integrated electrical connection device 7. After that, the cell assembly 2 is installed. Finally, the end cover 6 is closed to the opening of the housing 1 to seal the opening, and the end cover 6 is fixed to the housing 1 by the cooperation between the end cover 6 and the second mounting hole 112, thus completing the assembly of the entire battery swapping device.

[0058] A second aspect of this disclosure also provides a delivery vehicle, including the battery swapping unit described in the above embodiments and a battery tray, the battery tray being adapted to at least one battery swapping unit. In use, the battery swapping unit can be installed in the battery tray of the delivery vehicle to power the vehicle. Furthermore, the battery swapping unit using this disclosure has high space utilization in its casing 1, enabling the battery swapping unit to have a smaller volume, thereby facilitating the handling and replacement of the battery swapping unit by staff.

[0059] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0060] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0061] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
