[0042] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0043] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0044] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0045] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0046] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0047] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts.

[0048] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application.

It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0049] See also Figures 1 to 4 The present embodiment provides a transverse driving mechanism disposed in a container 300, and the transverse driving mechanism is used to drive the carrier 200 carrying the battery exchange device 100 to move transversely. The transverse driving mechanism includes a power member 1, a transfer member 2, a first moving member 3, a first transmission assembly 4, a second moving member 5, and a second transmission assembly 6.

[0050] Specifically, the power member 1 is arranged on the frame of the container 300, and the power member 1 is configured to provide a driving force. The transfer member 2 is arranged on the frame of the container 300, and the transfer member 2 includes an input end, a first output end, and a second output end. The power member 1 is transmission-connected to the input end, and the driving force provided by the power member 1 is distributed to the first output end and the second output end by the transfer member 2. The first moving member 3 is arranged on the frame of the container 300, and the first moving member 3 can reciprocate along a preset direction, and one end of the bearing member 200 is connected to the first moving member 3. The first output end is transmission-connected to the first moving member 3 via the first transmission assembly 4 to drive the first moving member 3 to move. The second moving member 5 is arranged on the frame of the container 300, and the second moving member 5 can reciprocate along a preset direction, and the other end of the bearing member 200 is connected to the second moving member 5. The second output end is transmission-connected to the second moving member 5 via the second transmission assembly 6 to drive the second moving member 5 to move. It should be noted that in this embodiment, the preset direction is the width direction of the container 300.

[0051] In actual applications, the driving force provided by the power member 1 is synchronously output through the first output end and the second output end of the transfer member 2, and then the first output end and the second output end respectively drive the first moving member 3 and the second moving member 5 to move, so as to drive the two ends of the carrier 200 to move synchronously. Compared with the structure in the prior art that uses multiple driving components to drive multiple positions of the carrier 200 to move synchronously, such a setting has a small synchronization error and stable operation, which can ensure the reliability and safety of the battery exchange device 100.

[0052] In this embodiment, the power part 1 is a servo motor, the transfer part 2 is a dual-output reducer, and the servo motor is installed on the dual-output reducer to form a drive part, thereby making the structure of the transverse drive mechanism more compact, reducing the space occupied in the container 300, and having high applicability.

[0053] It is worth noting that the coordination of servo motors and dual-output reducers needs to consider torque, speed, accuracy, specifications, and installation steps. Among them, the rated torque of the servo motor must be greater than the torque requirement of the actual application, and the rated torque of the reducer must be higher than or equal to the product of the rated torque of the motor multiplied by the transmission ratio. Select the appropriate servo motor speed according to the application requirements, and adjust the output speed by the transmission ratio of the reducer. Select servo motors and reducers with higher precision to ensure the operating accuracy of the entire system. Before installation, confirm that the motor and reducer are intact, strictly check whether the dimensions of the connection parts match, ensure concentricity during installation, and it is strictly forbidden to hit with a hammer to prevent damage to the bearings or gears. In addition, the specific models of servo motors and dual-output reducers are selected according to the actual application scenarios, and are not limited here.

[0054] Generally speaking, the container 300 used in the battery swap station is completely filled with battery packs and related components. Therefore, in order to improve the convenience of maintaining the drive unit, the drive unit is located at the top of the container 300, so that there is no need to disassemble the battery packs and related components in the container 300 when maintaining the drive unit, which is more convenient to operate.

[0055] In this embodiment, the structures of the first transmission assembly 4 and the second transmission assembly 6 are consistent, and the structure of the first transmission assembly 4 is taken as an example for explanation below.

[0056] The first transmission assembly 4 includes a plurality of transmission shafts 41 and a plurality of couplings 42 arranged in sequence. Any two adjacent transmission shafts 41 are connected by a coupling 42. The transmission shaft 41 located in the first position is connected to the first output end by a coupling 42, and the transmission shaft 41 located in the last position is connected to the first moving part 3 by a coupling 42. Due to manufacturing and installation reasons, there may be certain errors between the multiple connected transmission parts. In this embodiment, there may be certain errors between any two adjacent transmission shafts 41, the transmission shaft 41 located in the first position and the first output end, and the transmission shaft 41 located in the last position and the first moving part 3. Therefore, a coupling 42 is arranged between them, which can compensate for axial errors and buffer load impacts. In addition, the use of the coupling 42 can easily disassemble and maintain the drive unit without affecting the adjacent transmission shafts 41.

[0057] In particular, any one of the transmission shafts 41 can be configured as a universal joint. This configuration can adapt to the height difference between the drive unit and the first moving part 3, and achieve reliable transmission without additionally increasing the height of the container 300, that is, to achieve reliable transmission in a limited space. It can be understood that, on the one hand, the universal joint can compensate for the axis deviation caused by manufacturing and installation, ensuring the continuity and stability of the transmission system. On the other hand, the use of the universal joint reduces the requirements for installation accuracy, simplifies the installation process, and improves the assemblability of the equipment. In this embodiment, the first transmission assembly 4 includes three transmission shafts 41, of which the first and last two transmission shafts 41 are universal joints.

[0058] In this embodiment, the first moving member 3 and the second moving member 5 have the same structure, and the structure of the first moving member 3 is taken as an example for explanation below.

[0059] The first moving part 3 includes a driving sprocket 31, a driven sprocket 32 ​​and a chain 33. The driving sprocket 31 and the driven sprocket 32 ​​are rotatably arranged on opposite sides of the frame of the container 300, respectively. The chain 33 is wound around the driving sprocket 31 and the driven sprocket 32, and one end of the bearing member 200 is connected to the preset position of the chain 33. It can be understood that the chain transmission structure composed of the driving sprocket 31, the driven sprocket 32 ​​and the chain 33 drives the bearing member 200 to move. Since the chain transmission has the advantages of large transmission power, high transmission efficiency and strong overload capacity, it can ensure the reliability of the movement of the battery exchange device 100. In addition, the chain transmission structure composed of the driving sprocket 31, the driven sprocket 32 ​​and the chain 33 has a small size and can be applied to the narrow space in the container 300.

[0060] However, the chain 33 will gradually stretch during use, affecting the transmission accuracy. To solve this problem, an adjustment assembly 7 is provided between the driven sprocket 32 ​​and the frame of the container 300, and the adjustment assembly 7 is configured to adjust the position of the driven sprocket 32 ​​in a preset direction to tension the chain 33.

[0061] Specifically, the adjustment assembly 7 includes a mounting member 71, an adjustment member 72, a fixing member (not shown in the figure), and a rotating shaft 73. The mounting member 71 is arranged on the frame of the container 300. The adjustment member 72 is slidably arranged on the mounting member 71 along a preset direction and has an adjustment stroke. The fixing member is configured to fix the adjustment member 72 at any position within the adjustment stroke. The rotating shaft 73 is arranged on the adjustment member 72, and the driven sprocket 32 ​​is rotatably matched with the rotating shaft 73. Among them, the axial direction of the rotating shaft 73 is perpendicular to the preset direction.

[0062] In this embodiment, two adjusting members 72 are provided, and the two adjusting members 72 correspond to the two ends of the bearing rotating shaft 73, so as to ensure the structural strength of the adjusting assembly 7. Two fixing members are provided accordingly. Preferably, the fixing member is a bolt, because the bolt structure is simple in design, the installation process is relatively easy, and the fixing operation can be completed quickly.

[0063] When adjusting, first loosen the fixing member, then slide the adjusting member 72 along the preset direction, and then fix the adjusting member 72 to the mounting member 71 through the fixing member. Sliding the adjusting member 72 to the side away from the driving sprocket 31 drives the driven sprocket 32 ​​away from the driving sprocket 31, so as to achieve the effect of tensioning the chain 33.

[0064] This embodiment also provides a battery swap station, which includes a container 300, a carrier 200, a battery swap device 100, and the above-mentioned transverse drive mechanism, wherein the carrier 200 is arranged in the container 300 for transverse sliding, the battery swap device 100 is arranged on the carrier 200, and the transverse drive mechanism is arranged in the container 300 and is used to drive the carrier 200 to move transversely. It can be understood that the battery swap station including the above-mentioned transverse drive mechanism can ensure the reliability and safety of the battery swap device 100.

[0065] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
