[0032] Next, refer to Figures 1 to 4 Describe the carrying device according to some embodiments of this application.

[0033] Refer to Figures 1 to 4 As shown, the embodiments of this application provide a carrying device, including a material frame 1, a partition plate 2, and a first auxiliary limiting component 3; wherein, the partition plate 2 is arranged in the material frame 1, and the number of the partition plates 2 is multiple, and they are sequentially arranged at intervals along a first preset direction a to divide the inside of the material frame 1 into multiple installation cavities 14; multiple groups of first auxiliary limiting components 3 are arranged in any one of the installation cavities 14, and one of them is selected for use;

[0034] Any set of first auxiliary limiting components 3 includes two first auxiliary limiting members 31. The two first auxiliary limiting members 31 are respectively detachably connected to the opposite side walls of the installation cavity 14, and the two first auxiliary limiting members 31 are used to abut against the opposite sides of the object placed in the installation cavity 14 to limit the object; the dimensions of the first auxiliary limiting members 31 along the second preset direction b, such as the length dimensions, of the multiple sets of first auxiliary limiting components 3 configured for any installation cavity 14 are different. That is to say, the lengths of the two first auxiliary limiting members 31 in each set are the same, only the lengths of the first auxiliary limiting members 31 between different sets are different, and one set can be selected from the multiple sets of first auxiliary limiting components 3 according to actual needs for use, rather than using multiple sets of first auxiliary limiting components 3 together. In addition, it should be noted that: the object can be a battery, and this will also be used as an example for description later. Of course, the object is not limited to the battery, that is to say, the carrying device provided by the present application can also be used to carry other objects.

[0035] According to the structure described above, by using multiple partition plates 2 to divide the interior of the material frame 1 into multiple installation cavities 14, multiple batteries can be installed simultaneously, improving the efficiency of formation and grading. Moreover, each installation cavity 14 is provided with multiple sets of first auxiliary limiting components 3. Furthermore, first auxiliary limiting members 31 with different lengths can be selected according to batteries with different diameters, so as to change the distance between the two first auxiliary limiting members 31, thereby limiting batteries with different diameters and making the batteries more stable and not prone to shaking, etc.

[0036] Further, preferably, the two first auxiliary limiting members 31 in any set of first auxiliary limiting components 3 are respectively detachably connected to the opposite side walls of the material frame 1.

[0037] In this embodiment, preferably, as Figure 1 、 Figure 2 and Figure 4 shown, any first auxiliary limiting member 31 is respectively connected to the opposite sides of the material frame 1 by a snap connection.

[0038] According to the structure described above, the snap connection method is more convenient for operation and improves the convenience of assembly.

[0039] Further, preferably, a snap 311 is provided on the side of the first auxiliary limiting member 31, and the snap 311 is in the card slot opened at the top of the side plate 12.

[0040] It should be noted that: any first auxiliary limiting member 31 is respectively connected to the opposite sides of the material frame 1 not only by a snap connection, but also by bolts, plug-in connections and other ways to achieve detachable connection.

[0041] In this embodiment, preferably, as Figure 1 andFigure 2 As shown, the carrying device includes a second auxiliary limiting component 4. Multiple groups of second auxiliary limiting components 4 are provided in any installation cavity 14, and one of them is selected for use. Any group of second auxiliary limiting components 4 includes two second auxiliary limiting members 41. The two second auxiliary limiting members 41 are respectively detachably connected to the other opposite side walls of the installation cavity 14, and the two second auxiliary limiting members 41 are used to abut against the other opposite sides of the battery to limit the battery.

[0042] According to the above-described structure, for the battery in each installation cavity 14, in addition to using the two aforementioned first auxiliary limiting members 31 for positioning, in order to further reinforce the battery, two second auxiliary positioning members can also be used to limit the other two sides of the battery. Moreover, by changing the lengths of the two second auxiliary limiting members 41, the distance between the two second auxiliary limiting members 41 can be changed, so that batteries with different diameters can be positioned, improving the positioning effect and having a wider application range.

[0043] Furthermore, preferably, the two second auxiliary limiting members 41 are respectively detachably connected to two corresponding partition plates 2. Of course, it is not limited to this. The positions of the first auxiliary limiting component 3 and the second auxiliary limiting component 4 can be swapped, that is, the first auxiliary limiting member 31 is connected to the corresponding partition plate 2, and the second auxiliary limiting member 41 is directly connected to the side of the material frame 1, which is specifically selected according to actual needs.

[0044] Furthermore, preferably, the two first auxiliary limiting members 31 and the two second auxiliary positioning members limit the battery from four vertical directions, making the battery more stable and preventing problems such as shaking and displacement.

[0045] Furthermore, preferably, two adjacent installation cavities 14 can share a second auxiliary positioning member. That is to say, a second auxiliary positioning member is installed on the partition plate 2 between two adjacent installation cavities 14. And preferably, the second auxiliary limiting member 41 is U-shaped and can be clamped on the partition plate 2. The two sides of the second auxiliary positioning member respectively extend into the two installation cavities 14 on both sides of the partition plate 2, which plays the role of saving material costs and simplifying the assembly steps. Of course, it is not limited to this, and two second auxiliary positioning members can also be installed on the partition plate 2 between two adjacent installation cavities 14.

[0046] It should be noted that: this carrying device can also only include the first auxiliary limiting component 3 without setting the second auxiliary limiting component 4. Only the first auxiliary limiting component 3 is used to position the battery. Moreover, the first auxiliary positioning component can be directly installed on the side of the material frame 1 or directly installed on the partition plate 2, which is specifically selected according to actual needs.

[0047] In this embodiment, preferably, as Figure 1and Figure 2 As shown, the dimensions of the second auxiliary limiting members 41 in each of the multiple groups of second auxiliary limiting assemblies 4 provided in any installation cavity 14 along the first preset direction a, such as the length dimension, are different. That is to say, the lengths of all the second auxiliary limiting members 41 within each group are the same, only the length dimensions of the second auxiliary limiting members 41 between groups are different, and one group can be selected from the multiple groups of second auxiliary limiting assemblies 4 for use according to actual needs, rather than using all the second auxiliary limiting assemblies 4 together.

[0048] According to the structure described above, for each battery in each installation cavity 14, in addition to using the two aforementioned first auxiliary limiting members 31 for positioning, in order to further reinforce the battery, two second auxiliary positioning members can also be used to limit the other two sides of the battery. Moreover, by changing the lengths of the two second auxiliary limiting members 41, the distance between the two second auxiliary limiting members 41 can be changed, thereby enabling the positioning of batteries with different diameters, improving the positioning effect, and having a wider application range.

[0049] Furthermore, preferably, the two first auxiliary limiting members 31 and the two second auxiliary positioning members limit the battery from four vertical directions, making the battery more stable and preventing problems such as shaking and displacement.

[0050] Furthermore, preferably, two adjacent installation cavities 14 can share a second auxiliary positioning member. That is to say, a second auxiliary positioning member is installed on the partition plate 2 between two adjacent installation cavities 14. And preferably, the second auxiliary limiting member 41 is U-shaped and can be clamped on the partition plate 2. The two sides of the second auxiliary positioning member respectively extend into the two installation cavities 14 on both sides of the partition plate 2, which can save material costs and simplify the assembly steps. Of course, it is not limited to this, and two second auxiliary positioning members can also be installed on the partition plate 2 between two adjacent installation cavities 14.

[0051] It should be noted that: not only limited to the above-mentioned "the dimensions of the second auxiliary limiting members 41 in each of the multiple groups of second auxiliary limiting assemblies 4 provided in any installation cavity 14 along the first preset direction a, such as the length dimension, are different", it is also possible to make the dimensions of the second auxiliary limiting members 41 in all groups of second auxiliary limiting assemblies 4 along the first preset direction a, such as the length dimension, the same. In this case, if batteries of different sizes need to be installed, the second auxiliary limiting assemblies 4 can be disassembled and only the aforementioned first auxiliary limiting assemblies 3 are used.

[0052] In this embodiment, preferably, as Figure 1 and Figure 2 shown, each second auxiliary limiting member 41 is respectively connected to the corresponding partition plate 2 in a clamping manner.

[0053] According to the structure described above, the snap connection method is more convenient to operate and improves the convenience of assembly.

[0054] Further, preferably, the second auxiliary limiting member 41 is formed with a clamping groove and is snap-connected to the corresponding partition plate 2.

[0055] It should be noted that: any second auxiliary limiting member 41 and the corresponding partition plate 2 are not limited to being connected by snap connection, and can also be detachably connected by bolts, plug-in connection, etc.

[0056] In this embodiment, preferably, as Figures 1 to 3 shown, the material frame 1 includes a bottom plate 11, side plates 12 and end connectors 13; wherein, the number of end connectors 13 is two, and along the first preset direction a, the two end connectors 13 are respectively arranged at both ends of the bottom plate 11; the number of side plates 12 is two, and along the second preset direction b, the two side plates 12 are respectively arranged on both sides of the bottom plate 11; the side plates 12 are detachably connected to the corresponding first auxiliary limiting members 31, preferably the snap connection method described above. Of course, it is not limited to this. Specifically, it has been introduced above and will not be elaborated here.

[0057] According to the structure described above, the bottom plate 11, the end connectors 13 and the side plates 12 enclose the structure of the material frame 1, and the end connectors 13 can be used as the aforementioned erection parts and erected on the target ground to play a supporting role.

[0058] Further, preferably, the bottom plate 11 is a rectangular plate, and its length direction is the same as the first preset direction a; correspondingly, the side plate 12 is a rectangular plate, and its length direction is the same as the first preset direction a, and L-shaped notches are opened at both ends along its length direction to cooperate with the end connectors 13 and are erected on the fifth supporting member.

[0059] Further, preferably, the end connector 13 can be formed by assembling multiple plates with a hollow interior and an external cuboid shape, which plays the role of connecting the two side plates 12 and supporting.

[0060] In this embodiment, preferably, as Figures 2 to 4 shown, the partition plate 2 and the first auxiliary limiting member 31 are respectively connected to the bottom plate 11 by plug-in connection; the two side plates 12 and any end connector 13 are detachably connected by locking members such as screws or bolts.

[0061] According to the structure described above, it can be seen that the partition plate 2, the first auxiliary limiting member 31 and the bottom plate 11 all adopt a detachable connection method, the side plate 12 and the end connecting member 13 also adopt a detachable connection method, and the second auxiliary limiting member 41 and the partition plate 2 also adopt a detachable connection method, which is convenient for disassembling the whole material frame 1, facilitating packing and transportation. Moreover, when a certain component is damaged, it is extremely convenient to replace, improving the operation convenience.

[0062] Furthermore, preferably, a plugging convex portion 5 is formed at the bottom of the first auxiliary limiting member 31, the bottom plate 11 is formed with a plugging hole 17, and the plugging convex portion 5 is plugged into the plugging hole 17, thereby realizing a detachable connection method, which is convenient for installation and disassembly. Similarly, the partition plate 2 and the bottom plate 11 can also adopt the above connection structure, which will not be elaborated here.

[0063] It should be noted that: the partition plate 2 and the bottom plate 11 described above can also adopt a non-detachable connection method such as welding, which is specifically selected according to actual needs.

[0064] In addition, the side plate 12 and the end connecting member 13 can also adopt a non-detachable connection method such as welding, which is specifically selected according to actual needs.

[0065] In addition, in this embodiment, the side plate 12 is not directly connected to the bottom plate 11, but is connected to the bottom plate 11 through the first auxiliary limiting member 31. Of course, it is not limited to this, and the side plate 12 can also be directly connected to the bottom plate 11, including detachable and non-detachable connection methods.

[0066] In this embodiment, preferably, as Figure 3 shown, the number of the bottom plates 11 is multiple, and any bottom plate 11 is formed with a positioning groove 16, and the sizes of the positioning grooves 16 of each bottom plate 11 are different; multiple bottom plates 11 are selected for use.

[0067] According to the structure described above, it can be seen that this positioning groove 16 is used for positioning the battery. Therefore, for batteries with different diameters, multiple bottom plates 11 with different sizes of positioning grooves 16 can be configured, with a wider application range and better positioning effect for each type of battery.

[0068] Furthermore, preferably, the positioning groove 16 is a circular groove. Of course, it is not limited to this, and the positioning groove 16 can also be a square groove or other shaped grooves, which are selected according to actual needs.

[0069] It should be noted that: it is not limited to the above structure of setting multiple bottom plates 11, and only one bottom plate 11 can also be set, which is specifically selected according to actual needs.

[0070] In this embodiment, preferably, as Figure 3As shown, a through hole 15 is formed at the bottom of any one of the installation cavities 14, and this through hole 15 is located directly below the aforementioned positioning groove 16, mainly to avoid the detection probes during the processes of formation and grading. Of course, if other objects are installed in the installation cavity 14 and there is no need to operate on their bottoms, this through hole 15 can be completely cancelled.

[0071] In this embodiment, preferably, the carrying device further includes a protective frame (not shown in the figure). The protective frame extends along the first preset direction a and is detachably connected to the two end connectors 13 respectively, for resisting the upper side of the battery.

[0072] According to the structure described above, the protective frame is used to resist the upper side of the battery, further playing a role in limiting and protecting the battery, and avoiding the battery from tipping or shifting, etc.

[0073] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
