[0041] In this application, unless otherwise specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integration; mechanical connections, electrical connections, direct connections, or indirect connections through an intermediary; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0042] In the description of this specification, if the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" appear, it means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0043] The “X direction”, “Y direction” and “Z direction” mentioned in the description of this application are all judged based on the rectangular coordinate system constructed by the battery testing device 100, wherein the X direction is also vertical, the Y direction is also horizontal, and the Z direction is also vertical.

[0044] Figure 1 FIG. 1 is a schematic diagram of a battery testing device 100 provided according to one embodiment of the present application. Figure 2 for Figure 1 Schematic diagram of the battery testing device 100 from another perspective. Figure 3 for Figure 1 Schematic diagram of the assembly of the cabinet frame 10, the lifting movable frame 20 and the driving device 30 in the battery testing equipment 100. Figures 1 to 3 The battery testing device 100 includes a cabinet frame 10 , a lifting movable frame 20 and at least one driving device 30 .

[0045] The lifting frame 20 is used to load the battery tray 600. The cabinet frame 10 is formed with a battery tray aisle D and includes a plurality of frame columns 11 located on opposite sides of the battery tray aisle D in the Y direction. The battery tray aisle D can accommodate at least part of the lifting frame 20. The frame columns 11 are in rolling connection with the lifting frame 20.

[0046] The driving device 30 is disposed on the cabinet frame 10 and connected to the lifting movable frame 20 to drive the lifting movable frame 20 to move along the frame column 11 in the Z direction.

[0047] In this embodiment, the battery testing device 100, except for the cabinet frame 10, is arranged based on the cabinet frame 10. The cabinet frame 10 can be a frame structure assembled from multiple beams, wherein some of the vertically arranged beams serve as frame columns 11. These frame columns 11 can serve both load-bearing and guiding functions. In other words, the frame columns 11 have dual functions, serving as both support and guidance, which can avoid the need for additional functional components for guidance, simplify the structure, and help improve the structural compactness of the cabinet frame 10.

[0048] In addition, these beams are assembled to form a battery tray aisle D. At least a portion of the lifting movable frame 20 is located in the battery tray aisle D. The battery tray aisle D is configured to allow the battery tray 600 to pass through so that it can be placed on the lifting movable frame 20.

[0049] The lifting movable frame 20 is movably connected to the frame column 11 and can move along the Z direction, that is, lift and lower movement, under the drive of the driving device 30.

[0050] In particular, the lifting frame 20 is coupled to the frame columns 11 in a rolling manner to achieve a movable connection with the cabinet frame 10. In other words, the lifting frame 20 is movably coupled to the cabinet frame 10 through a rolling connection, replacing the existing method of achieving a movable connection using a linear bearing guide mechanism. This reduces assembly precision requirements, facilitates assembly work for assemblers, simplifies the assembly process, and ultimately reduces costs.

[0051] Figure 1 The battery tray 600 is shown placed on the lifting frame 20 within the battery tray aisle D. In the illustrated embodiment, there are two drive devices 30, which are arranged opposite each other in the Y direction. There are four frame columns 11, which are also arranged opposite each other in the Y direction. There are two frame columns 11 on each side, which are spaced apart in the X direction. The drive device 30 on each side is located between the two frame columns 11 on each side.

[0052] In order to avoid interference with the frame columns 11 and the driving device 30 , a handling facility is generally used to transport the battery tray 600 along the X direction into the battery tray aisle D and place it on the lifting movable frame 20 .

[0053] Since the precision requirement is not high, the driving device 30 in the illustrated embodiment is a cylinder, which has a relatively low cost. Of course, it is not limited to this. The driving device 30 can also adopt, for example, a linear motor, an electric cylinder, etc.

[0054] Figure 4a Schematic diagram of a rolling mechanism 22 provided according to one embodiment of the present application. Figure 4b for Figure 4aA schematic diagram of the rolling mechanism 22 in another perspective. Figure 4a and Figure 4b In some optional embodiments, the lifting frame 20 includes a plurality of rolling mechanisms 22 , each of which is in rolling connection with a corresponding frame column 11 . The rolling mechanism 22 includes a mounting seat 221 and at least one floating rolling assembly 222 .

[0055] The floating rolling assembly 222 is connected to the mounting seat 221 and can roll along the corresponding frame column 11. The floating rolling assembly 222 is configured to be movable in the direction of the connecting plane intersecting the corresponding frame column 11 to maintain contact with the frame column 11 during the rolling process.

[0056] In this embodiment, the lifting movable frame 20 is connected and cooperated with the multiple frame columns 11 through multiple rolling mechanisms 22. The number of the rolling mechanisms 22 is the same as the number of the frame columns 11, and the two are in one-to-one correspondence.

[0057] The rolling mechanism 22 at least includes a mounting seat 221 and at least one floating rolling assembly 222 . The floating rolling assembly 222 is fixedly mounted on the mounting seat 221 and can be connected to the corresponding frame column 11 and can roll along the connecting plane of the frame column 11 .

[0058] In addition, the floating rolling component 222 has a certain degree of freedom of movement. The freedom of movement here refers not only to its ability to roll, but also to its ability to move in the direction of the connecting plane intersecting the frame column 11, that is, it floats in the direction of the connecting plane intersecting the frame column 11, so that the floating rolling component 222 always maintains a state of abutting against the frame column 11.

[0059] Such an arrangement enables each floating rolling assembly 222 to always maintain an abutting state with the corresponding frame column 11 , thereby ensuring the stability and reliability of the lifting movable frame 20 during the movement process.

[0060] Please combine Figure 3 ,exist Figure 3 In the illustrated embodiment, the lifting movable frame 20 further includes a movable frame 21. Four rolling mechanisms 22 are provided on the movable frame 21 to achieve a one-to-one connection with the four frame columns 11. Under the action of the drive device 30, each rolling mechanism 22 rolls along the corresponding frame column 11 during the lifting and lowering process of the movable frame 21.

[0061] Since the floating rolling components 222 in each rolling mechanism 22 always maintain contact with the corresponding frame column 11 during the rolling process, the movable frame 21 can maintain linear motion as much as possible during the up and down movement, thereby ensuring that the battery tray 600 placed on the movable frame 21 always maintains linear motion, which can reduce the risk of the battery tray 600 tilting.

[0062] It should be noted that in the illustrated embodiment, the floating rolling components 222 float in the direction of the connecting plane perpendicular to the frame column 11. It should be understood that floating in the direction of the connecting plane perpendicular to the frame column 11 is a form of movement in the direction of the connecting plane intersecting the frame column 11.

[0063] In a further optional embodiment, the rolling mechanism 22 further includes a positioning guide module, which includes a positioning sleeve 224 , which is arranged on the upper side of the mounting seat 221 in the Z direction.

[0064] The cabinet frame 10 further includes a plurality of limiting shafts 12 . Each limiting shaft 12 is connected to a corresponding frame column 11 and is located above the rolling mechanism 22 in the Z direction. Each limiting shaft 12 can be plugged into a corresponding positioning sleeve 224 .

[0065] In this embodiment, the rolling mechanism 22 further includes a positioning guide module. The positioning guide module includes at least a positioning sleeve 224 . The positioning sleeve 224 is fixedly mounted on the top side of the mounting seat 221 .

[0066] The cabinet frame 10 also has multiple limit shafts 12. The number of limit shafts 12, the number of rolling mechanisms 22 and the number of frame columns 11 are the same. There is a corresponding limit shaft 12 on each frame column 11 to cooperate with the corresponding rolling mechanism 22, specifically with the positioning sleeve 224 in the rolling mechanism 22.

[0067] Specifically, when the driving device 30 drives the lifting movable frame 20 to move upward, the rolling mechanism 22 moves upward along the frame column 11. During the upward movement, each limiting shaft 12 can be inserted into the positioning sleeve 224 in the corresponding rolling mechanism 22.

[0068] It should be noted that existing equipment using linear bearing guide mechanisms can directly achieve high-precision docking of the battery tray 600 with the detection function module. It should be understood that because the floating rolling assembly 222 is capable of floating in the direction of the plane intersecting the frame columns 11, the entire lifting frame 20 will inevitably experience slight horizontal shaking during the upward movement. Therefore, a limit shaft 12 is provided on each frame column 11 to cooperate with the corresponding positioning sleeve 224 to ensure the docking accuracy of the battery tray 600 in the lifting frame 20.

[0069] In other words, the lifting frame 20 is allowed to slightly shake horizontally in the first half of the upward movement. In the second half of the upward movement, as the insertion depth of the limit shaft 12 increases, the lifting frame 20 is precisely positioned to ensure the docking accuracy of the battery tray 600.

[0070] In a specific application, the lower portion of the limiting shaft 12 is designed to be conical, so that as the lower portion of the limiting shaft 12 is gradually inserted, the range of movement of the lifting movable frame 20 is gradually limited, and precise positioning is gradually completed.

[0071] Furthermore, the positioning and guiding module further includes a limiting gasket 223 , which is arranged on the upper side of the mounting seat 221 in the Z direction and surrounds the outer peripheral side of the positioning sleeve 224 to limit the upper limit of the lifting movable frame 20 .

[0072] When the lifting movable frame 20 is at the upper limit position, each limiting shaft 12 is inserted into the corresponding positioning sleeve 224 and connected to the corresponding limiting gasket 223 .

[0073] In this embodiment, the positioning and guiding module further includes a limiting gasket 223 . The limiting gasket 223 surrounds the outer circumference of the positioning sleeve 224 and is located on the same side of the mounting seat 221 in the Z direction as the positioning sleeve 224 .

[0074] It should be understood that as the insertion depth of the limiting shaft 12 in the positioning sleeve 224 increases, the limiting shaft 12 can abut against the limiting gasket 223. In other words, the limiting gasket 223 is used to limit the insertion depth of the limiting shaft 12 in the positioning sleeve 224, thereby achieving the upper limit of the lifting movable frame 20.

[0075] It can be seen that by combining the limiting gasket 223 and the positioning sleeve 224 to cooperate with the limiting shaft 12, the docking accuracy requirements of the battery tray 600 are all converted to the lifting movable frame 20, which can not only ensure the positioning accuracy, but also effectively reduce the processing accuracy of related components.

[0076] It should be noted that when the elevating frame 20 is in the upper limit position, the battery tray 600 located therein is in the inspection position. The docking accuracy of the battery tray 600 refers to the docking accuracy between the battery terminals in the battery tray 600 and the inspection module. The lower limit accuracy requirement for the elevating frame 20 is less stringent and can be determined by the travel range of the drive device 30.

[0077] exist Figure 3In the illustrated embodiment, the lifting frame 20 is in the upper limit position. At this time, each rolling mechanism 22 is connected to the corresponding limit shaft 12. As can be seen from the above, the entire lifting frame 20 always maintains translation during the movement, so each limit shaft 12 can be simultaneously inserted into the positioning sleeve 224 in the corresponding rolling mechanism 22 and connected to the limit gasket 223. In this way, the lifting frame 20 remains horizontal when it is in the upper limit position.

[0078] In some optional embodiments, there are multiple floating rolling assemblies 222 , and the multiple floating rolling assemblies 222 are connected to two side surfaces of the frame column 11 .

[0079] In this embodiment, a single rolling mechanism 22 has a plurality of floating rolling components 222 , and these floating rolling components 222 are connected to different sides of the frame column 11 , thereby ensuring that contact points in different orientations are formed between the single rolling mechanism 22 and the corresponding frame column 11 , thereby further reducing the degrees of freedom of the single rolling mechanism 22 .

[0080] For example, the plurality of floating rolling elements 222 in a single rolling mechanism 22 are connected to two opposite side surfaces of the frame column 11 , so that the single rolling mechanism 22 only has the freedom of movement in the up-down direction.

[0081] In a further optional embodiment, the mounting base 221 includes a vertical plate segment 2211 and an ear plate segment, wherein the ear plate segment includes an X-direction ear plate segment 2212 and a Y-direction ear plate segment 2213. The X-direction ear plate segment 2212 extends from the vertical plate segment 2211 along the X direction, and the Y-direction ear plate segment 2213 extends from the vertical plate segment 2211 along the Y direction.

[0082] The limiting washer 223 and the positioning sleeve 224 are both located on the vertical plate segment 2211. The X-direction ear plate segment 2212 and the Y-direction ear plate segment 2213 each have at least one floating rolling assembly 222. Each rolling mechanism 22 is located inside the corresponding frame column 11, and each floating rolling assembly 222 is disposed between the corresponding frame column 11 and the mounting base 221.

[0083] In this embodiment, the mounting base 221 is composed of at least one vertical plate segment 2211 and two ear plate segments, wherein the two ear plate segments are an X-direction ear plate segment 2212 and a Y-direction ear plate segment 2213 .

[0084] The X-direction ear plate segment 2212 is located on the X-direction side of the vertical plate segment 2211, and the Y-direction ear plate segment 2213 is located on the Y-direction side of the vertical plate segment 2211. This creates an L-shaped cross-section of the mounting base 221. Furthermore, each of the X-direction ear plate segment 2212 and the Y-direction ear plate segment 2213 is fixedly mounted with at least one floating rolling assembly 222. This allows multiple floating rolling assemblies 222 in different locations to engage with both sides of the frame column 11.

[0085] Furthermore, since each rolling mechanism 22 is located on the inner side of the corresponding frame column 11, the multiple floating rolling components 222 at different positions in each rolling mechanism 22 are connected to the two inner side surfaces of the corresponding frame column 11. In this way, the lifting movable frame 20 can be limited in multiple degrees of freedom through multiple frame columns 11 at different positions, so that the lifting movable frame 20 only has the lifting freedom degree.

[0086] Furthermore, each floating rolling assembly 222 of each rolling mechanism 22 is clamped between the frame column 11 and the mounting seat 221 , and the floating rolling assembly 222 has a floating degree of freedom in a direction perpendicular to the contact surface, so that it can always be in close contact with the frame column 11 .

[0087] Please combine Figure 3 In the embodiment shown, the frame column 11 is a rectangular beam, the floating rolling assembly 222 on the X-direction ear plate segment 2212 is connected to the X-direction inner side of the frame column 11, and the floating rolling assembly 222 on the Y-direction ear plate segment 2213 is connected to the Y-direction inner side of the frame column 11.

[0088] Furthermore, the number of rolling mechanisms 22 is 4. Figure 3 Only two rolling mechanisms 22 spaced apart in the X direction are shown. These two rolling mechanisms 22 are just limited by the two outer frame columns 11, so that the rolling mechanisms 22 only have the freedom of up and down movement. It can be seen that the four rolling mechanisms 22 in the entire lifting movable frame 20 are just limited by the four outer frame columns 11, so that the entire lifting movable frame 20 only has the freedom of up and down movement.

[0089] It should be noted that the internal and external relationship here is mainly determined based on the center of the cabinet frame 10 as a reference.

[0090] Furthermore, when there are multiple floating rolling assemblies 222 on the ear plate segment, the multiple floating rolling assemblies 222 on the ear plate segment are spaced apart along the Z direction.

[0091] In this embodiment, the number of floating rolling assemblies 222 on a single lug segment is preferably no less than two, to maximize stability during rolling. In the embodiment shown in Figure 4 , the number of floating rolling assemblies 222 on both the X-direction lug segment 2212 and the Y-direction lug segment 2213 is two, and these two floating rolling assemblies 222 are spaced apart in the Z-direction. Of course, the number of floating rolling assemblies 222 on a single lug segment is not limited to this and can be adjusted as needed.

[0092] In a further optional embodiment, the floating rolling assembly 222 includes a rolling member 2221 , an elastic member 2222 , a sliding block 2223 and a mounting block 2224 .

[0093] The mounting blocks 2224 are located on opposite sides of the rolling element 2221 and are each provided with a sliding hole H1 . Slide blocks 2223 and elastic members 2222 are respectively provided in the sliding holes H1 on both sides. The rolling element 2221 is rotatably connected to the slide blocks 2223 on both sides.

[0094] The mounting blocks 2224 on both sides are connected to the ear plate segments and allow the rolling element 2221 to partially protrude from the ear plate segments. The elastic elements 2222 in the sliding holes H1 on both sides allow the rolling element 2221 to maintain contact with the frame column 11 via the sliders 2223 .

[0095] In this embodiment, the floating rolling assembly 222 comprises at least a rolling element 2221, an elastic element 2222, a slider 2223, and a mounting block 2224. The elastic element 2222, the slider 2223, and the mounting block 2224 are arranged on opposite sides of the rolling element 2221. The mounting block 2224 defines a sliding hole H1, and the elastic elements 2222 and the sliders 2223 on either side are correspondingly positioned within the sliding holes H1 in the mounting block 2224 on either side.

[0096] The mounting block 2224 is connected to the ear plate section, and a portion of the mounting block 2224 is embedded in the ear plate section, and the rolling element 2221 is allowed to protrude from the ear plate section, ensuring that the rolling element 2221 can be connected to the frame column 11.

[0097] Furthermore, the rolling element 2221 is rotatably connected to the slider 2223 in the mounting block 2224, allowing the rolling element 2221 to rotate freely. Furthermore, the slider 2223 can move within the slide hole H1, preventing the rolling element 2221 from getting stuck. Furthermore, the elastic member 2222 can apply pressure to the slider 2223 toward the frame column 11, allowing the rolling element 2221 to float in a direction perpendicular to the contact surface of the frame column 11, ensuring that the rolling element 2221 always remains in close contact with the frame column 11.

[0098] exist Figure 4a and Figure 4bIn the illustrated embodiment, the rolling element 2221 is a roller, with rotating shafts formed on opposite sides of the roller to form a rotational connection with the sliders 2223 on both sides. The elastic element 2222 can be a spring and is arranged to extend in a direction perpendicular to the contact surface of the frame column 11. Of course, the rolling element 2221 is not limited to a roller and can also be, for example, a roller, a ball, etc. The elastic element 2222 is not limited to a spring and can also be elastic rubber, an elastic sheet, etc.

Figure 1 、 Figure 2 and Figure 5 In some optional embodiments, the battery testing device 100 further includes a drawer frame assembly 40, which is movably connected to the cabinet frame 10. The drawer frame assembly 40 includes a probe module 42, which is located above the lifting movable frame 20 in the Z direction.

[0100] In this embodiment, the battery testing apparatus 100 further includes a drawer frame assembly 40, which is integrated with a probe module 42. The probe module 42 is used for battery testing and is located above the elevating frame 20. When the elevating frame 20 reaches its upper limit, batteries loaded in the battery tray aisle D can connect to the probes in the probe module 42, preparing for battery testing.

[0101] It should be noted that the docking and pressing of the probes with the battery poles in the battery tray 600 is not limited to being at the upper limit position, and the docking can also be achieved before the upper limit position through the control of the driving device 30.

[0102] Furthermore, the drawer frame assembly 40 is provided with slide rails 41 . The slide rails 41 extend along the X direction and are located on two opposite sides of the drawer frame assembly 40 in the Y direction.

[0103] In this embodiment, slide rails 41 are integrated on both sides of the drawer frame assembly 40 in the Y direction. The slide rails 41 extend along the X direction, so that the drawer frame assembly 40 can be drawn along the X direction.

[0104] It should be noted that the drawer frame assembly 40 also integrates a heat dissipation fan, a DCDC power module, etc. The drawer frame assembly 40 is configured to be drawable to facilitate maintenance of the modules integrated on the drawer frame assembly 40.

[0105] See also Figure 1 In some optional embodiments, the battery testing device 100 further includes an air duct assembly 50 , which is disposed in the cabinet frame 10 and located on both sides of the battery tray aisle D in the Y direction.

[0106] In this embodiment, the air duct components 50 are located on both sides of the battery tray aisle D in the Y direction. The air duct components 50 on both sides are close to the battery tray 600 to achieve air duct system circulation and facilitate heat dissipation of the battery tray 600.

[0107] In the illustrated embodiment, air duct installation spaces C are formed on both sides of the battery tray aisle D in the Y direction. The air duct assembly 50 is located in the air duct installation space C, and the cabinet frame 10 can protect the air duct assembly 50.

[0108] In addition to the frame columns 11 , the cabinet frame 10 also includes outer columns 13 . The outer columns 13 are located outside the frame columns 11 . An air duct installation space C is formed between the frame columns 11 and the outer columns 13 . Of course, the outer columns 13 mainly play a supporting role.

[0109] In some optional embodiments, the battery testing device 100 further includes a fire door and a maintenance door (not shown in the figures), which are both connected to the cabinet frame 10 and are located on opposite sides of the battery tray aisle D in the X direction.

[0110] In this embodiment, a fire door and a maintenance door are installed on opposite sides of the battery tray aisle D in the X direction. Battery trays 600 must pass through the fire door to enter and exit the battery tray aisle D. In the event of a fire within the cabinet frame 10, the fire door can be closed to prevent the fire from spreading. The maintenance door primarily facilitates maintenance personnel.

[0111] It should be noted that the existing battery testing equipment assembly adopts a 2X2 battery testing equipment solution arranged in a large cabinet. Specifically, the four testing units and the mechanical unit are locked in the large cabinet to form a 2X2 battery testing equipment solution. This makes the entire battery testing equipment assembly too large and cannot be disassembled, making it inconvenient to transport and difficult to install.

[0112] Another aspect of the present application provides a battery testing device assembly, which includes multiple battery testing devices 100 as described above. As can be seen from the foregoing, the battery testing devices 100 do not require high assembly precision, and even stacking multiple battery testing devices 100 can meet the assembly precision requirements. Therefore, a solution is adopted in which the mechanical unit and the testing unit are integrated in a small cabinet. Multiple battery testing devices 100 can be stacked as needed to form a battery testing device assembly.

[0113] As can be seen from the foregoing, the battery tray 600 enters the battery tray aisle D along the X direction. In order to avoid interference with the transportation of the battery tray 600, multiple battery testing devices 100 are stacked in the Y direction and / or the Z direction.

[0114] For example, for two battery testing devices 100, the two battery testing devices 100 can be stacked in the Y direction or in the Z direction. For four battery testing devices 100, a layout scheme of two battery testing devices 100 stacked in the Y direction can be formed in two layers in the Z direction.

[0115] Thus, the present application adopts a stacking and splicing solution of splitting a battery testing device assembly into multiple battery testing devices 100, which is convenient for assembly and transportation, and reduces costs and increases efficiency.

[0116] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
