[0052] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0054] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0055] Power battery refers to the power source that provides power for tools, mostly refers to the storage battery that provides power for electric vehicles. Power lithium batteries have been widely used in new energy vehicles due to their large capacity and strong environmental protection, and are the core components of new energy vehicles. Among them, power lithium batteries mainly include lithium iron phosphate batteries, lithium manganese oxide batteries and ternary material batteries.

[0056] Power batteries have a large weight. In order to ensure the safety of power batteries during mass manufacturing, related technologies usually use dedicated transfer devices to transport power batteries.

[0057] However, since power batteries themselves have various models and specifications, currently multiple models of power battery transport devices are required for power batteries of different sizes and specifications, which not only increases production costs, but also affects the transportation efficiency of power batteries.

[0058] In order to solve the above technical problems, the present application provides a power battery transport device. The power battery transport device provided by the present application is described in detail below with reference to the accompanying drawings of the specification.

[0059] Please refer to Figure 1 and Figure 2 The present application proposes a power battery transport device, which includes a mounting frame 1, a support assembly 2 and a moving wheel 3. The mounting frame 1 includes two first beams 11 arranged at intervals; the support assembly 2 includes a plurality of supporting beams 21 and a fastener 22; the two ends of the supporting beam 21 are respectively connected to the two first beams 11 and the supporting beam 21 can move along the length direction X of the first beam 11; the fastener 22 is used to fix the supporting beam 21 to the first beam 11; the moving wheel 3 is arranged at the bottom of the mounting frame 1.

[0060] The power battery transport device provided in the embodiment of the present application is provided with a support beam 21 movable along the length direction X of the first beam 11 on the first beam 11. By adjusting the position of the support beam 21 on the first beam 11 and using a fastener 22 to fix the support beam 21 at the set position to the first beam 11, it can be applied to the transport of power batteries of various sizes. It can be seen that the present application can simultaneously meet the transport of power batteries of various sizes, effectively reducing production costs and improving transportation efficiency.

[0061] The specific structure of the power battery transport device is introduced in detail below in conjunction with the drawings in the specification.

[0062] See also Figure 1 and Figure 2 The two ends of the supporting beam 21 are respectively connected to the two first beams 11 and the supporting beam 21 can move along the length direction X of the first beam 11 .

[0063] There are many ways to connect the support beam 21 to the first beam 11. For example, see Figure 3 and Figure 5 , a connecting hole 110 is provided on the first crossbeam 11; both ends of the supporting crossbeam 21 have connecting parts 210, the connecting parts 210 are mounted on the first crossbeam 11 and have plug-in holes 2111 corresponding to the connecting holes 110; accordingly, the fastener 22 can be a plug-in connector, which is inserted through the plug-in hole 2111 and the connecting hole 110. When the first crossbeam 11 is moved and the plug-in hole 2111 of the connecting part 210 on the first crossbeam 11 is aligned with the connecting hole 110 on the first crossbeam 11, the fastener 22 is inserted into the plug-in hole 2111 and the connecting hole 110, so that the connection between the supporting crossbeam 21 and the first crossbeam 11 can be achieved. In addition, the supporting crossbeam 21 can also be connected to the first crossbeam 11 by means of clamping or the like.

[0064] It should be noted that when the form of the connecting hole 110 on the first cross beam 11 is different, the structural form of the fastener 22, ie, the connector, is also different.

[0065] In one possible implementation, Figure 3 As shown, the connecting hole 110 on the first beam 11 can be a circular hole 111, and the number of the circular holes 111 can be multiple, and the multiple circular holes 111 are arranged at intervals along the length direction X of the first beam 11. The spacing between adjacent circular holes 111 can be flexibly set according to actual needs, and the present application does not make specific restrictions on this. Among them, the fastener 22, that is, the connector, can be a pin or a countersunk screw. When using a power battery transport device to transport power batteries of different sizes, it is only necessary to align the plug-in holes 2111 of the connecting parts 210 at both ends of the support beam 21 with the corresponding circular holes 111 on the first beam 11, and then insert the fastener 22, that is, the connector, into the plug-in hole 2111 and the connecting hole 110, so as to adjust the support position of the support beam 21. For example, see Figure 2 , Figure 3 and Figure 5 , when transporting the largest size power battery, for Figure 2 The support beam 21 on the left side of the middle can be moved to the left to align the plug hole 2111 of the connecting portion 210 with the first round hole 111 on the left side of the first beam 11, and then the support position of the support beam 21 can be adjusted by inserting the plug-in part into the plug hole 2111 and the connecting hole 110. Figure 2 The supporting beam 21 on the left side can be moved from left to right to align the plug-in hole 2111 of the connecting portion 210 with the other round holes 111 on the first beam 11, and then the supporting position of the supporting beam 21 can be adjusted by inserting the connector into the plug-in hole 2111 and the connecting hole 110.

[0066] In another possible implementation, Figure 4As shown, the connecting hole 110 can be an elongated hole 112 extending along the length direction X of the first beam 11. The length of the elongated hole 112 can be flexibly set according to actual needs, and the present application does not make specific restrictions on this. It should be noted that, unlike the fastener 22 in the above embodiment, the fastener 22, i.e., the connector, can be a bolt assembly (not shown in the figure), and the bolt assembly includes a bolt and a nut, and the screw of the bolt is passed through the plug hole 2111 and the connecting hole 110, and the nut is threadedly connected to the screw. When using a power battery transport device to transport power batteries of different sizes, it is only necessary to loosen the screw on the nut and the bolt to release the fixed connection between the support beam 21 and the first beam 11. Then, by moving the bolt assembly on the support beam 21 and its connecting portion 210, and then tightening the nut and the screw on the bolt, the position of the support beam 21 on the first beam 11 can be adjusted.

[0067] See also Figure 5 and Figure 6 In some embodiments of the present application, the connection part 210 at both ends of the support beam 21 may include a connection body 211, and the connection body 211 is provided with the connection hole 110 described in the above embodiment. In addition, considering the connection between the connection part 210 and the support beam 21 and facilitating the processing and manufacturing of the connection part 210, the connection part 210 may also include a first bending part 212. The first bending part 212 is arranged at one end of the connection body 211 and is arranged at an angle with the connection body 211; wherein, the angle between the first bending part 212 and the connection body 211 may be matched according to the end surface, i.e., the end face shape of the support beam 21. When the end face of the support beam 21 is a plane, the angle between the first bending part 212 and the connection body 211 is a right angle, and when the end face of the support beam 21 is an inclined surface, the angle between the first bending part 212 and the connection body 211 may be an acute angle or an obtuse angle. The first bending part 212 may be fixedly connected to the end of the support beam 21 by welding, bonding, etc.

[0068] Please continue to see Figure 6 In some embodiments of the present application, in order to improve the stability of the support beam 21 overlapped on the first beam 11, the connecting portion 210 may further include a second bending portion 213, and the second bending portion 213 is arranged at the other end of the connecting body 211; the second bending portion 213 and the first bending portion 212 have the same orientation. Among them, the distance between the second bending portion 213 and the first bending portion 212 is adapted to the width of the first beam 11. In this way, the connecting portion 210 can be buckled on the first beam 11. The first bending portion 212 and the second bending portion 213 cooperate with each other to prevent the support beam 21 from moving horizontally. In addition, the first bending portion 212 and the second bending portion 213 can also form a slideway to guide the support beam 21 to move along the length direction X of the first beam 11.

[0069] See also Figure 1 and Figure 2 In some embodiments of the present application, the mounting frame 1 may further include a plurality of connecting beams 12, and the two ends of the connecting beams 12 are respectively connected to the two first beams 11. The connecting beams 12 are located between the plurality of supporting beams 21. In this way, by connecting the first beams 11 with the connecting beams 12, the rigidity of the power battery transport device can be improved, so that the supporting beams 21 can move more stably on the first beams 11 along the length direction X of the first beams 11. Figure 2 As shown, the number of connecting beams 12 can be two, and of course it can also be set to three, four, etc. according to actual needs. A gap can be reserved between two adjacent connecting beams 12. In order to improve the applicability of the power battery transport device as much as possible, the connecting beam 12 is set in the middle of the first beam 11 as much as possible.

[0070] Since the connecting crossbeam 12 is arranged in the middle of the first crossbeam 11, the power battery may be subjected to the supporting pressure exerted by the connecting crossbeam 12 during transportation. In order to avoid the power battery being damaged by the excessive supporting pressure, see Figure 2 In some embodiments of the present application, an anti-skid pad 121 is further provided on the connecting crossbeam 12. The anti-skid pad 121 can be provided on the top surface of the connecting crossbeam 12. The anti-skid pad 121 has a certain thickness so as to provide sufficient buffering effect. The anti-skid pad 121 can be made of a flexible material, such as a silicone block, a rubber block, etc.

[0071] See also Figure 1 In some embodiments of the present application, the mounting frame 1 may further include a chassis 13 and a plurality of columns 14, the moving wheels 3 are arranged at the bottom of the chassis 13; one end of the column 14 is fixedly connected to the chassis 13, and the other end of the column 14 is fixedly connected to the first cross beam 11. The chassis 13 serves as the basis of the entire power battery transport device, and may be a frame structure or a plate structure. Figure 1 As shown, when the chassis 13 is a frame structure, the mounting frame 1 may further include a tool box 16, which is mounted on the chassis 13. The columns 14 are used as connecting members between the chassis 13 and the first crossbeam 11, and can support the first crossbeam 11 at a predetermined height. The number of columns 14 can be as follows: Figure 1 There are four columns 14 shown, and the four columns 14 respectively support the four ends of the two first beams 11. In addition, the columns 14 can also be designed as telescopic parts. In this way, the height of the first beam 11 at the top of the columns 14 can be adjusted by telescoping the columns 14, so that it is suitable for application scenarios that require the height of the first beam 11. In order to enhance the overall rigidity of the power battery transport device, the mounting frame 1 can also include a reinforcing rod 15, which is fixedly arranged between the columns 14. Figure 1 As shown, a reinforcing rod 15 may be provided between adjacent columns 14. Figure 1 The mobile wheel 3 can be a fixed caster or a movable caster, i.e., a universal wheel. The universal wheel has a rotating structure and can rotate not only vertically but also horizontally, so it is convenient to move the power battery transport device. The number of the mobile wheels 3 can be three, four, etc., such as Figure 1 As shown, four moving wheels 3 may be provided at the bottom of the chassis 13 corresponding to the four columns 14 .
