DETAILED DESCRIPTION

[0023] It should be noted that the embodiments and the features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all the technical and scientific terms used in the present application have the same meaning as that generally understood by the ordinary skilled in the art to which the present application belongs.

[0025] In the present application, unless otherwise specified, the orientation words such as "upper, lower, top, bottom" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer relative to the contour of the components themselves, but the above orientation words are not used to limit the present application.

[0026] In order to solve the problem that the output pole of the battery module in the prior art cannot adapt to part of use scenarios, the utility model provides a leading pole structure of battery module and battery module.

[0027] As Figures 1 to 5 shown, a leading pole structure of battery module includes: first conductor 10, second conductor 20 and seat body 30. First conductor 10 is located at the end of battery 50 and is electrically connected with battery 50. Second conductor 20 is in contact with first conductor 10, and second conductor 20 extends transversely from the side of battery 50. Second conductor 20 includes at least four connecting segments, and each connecting segment is sequentially connected by bending and forms at least three bending structures. Seat body 30 is located at the side of battery 50, and second conductor 20 extends to seat body 30 and is connected with seat body 30.

[0028] As Figure 1 shown, the embodiment sets second conductor 20, and second conductor 20 extends transversely from the side of battery 50, so that the leading pole structure as a whole forms a transversely extending structure. Compared with the conventional structure that extends longitudinally upward, the leading pole structure of the embodiment can be applied to use scenarios such as insufficient space above, thereby improving the adaptability of the leading pole structure to use scenarios and improving applicable scenarios. Considering that battery 50 may expand in actual use, the embodiment adopts the structure of at least four bent connecting segments for second conductor 20. In this way, second conductor 20 forms a structure of at least three bends, so that the displacement generated by the expansion of battery 50 can be absorbed when battery 50 expands, avoiding the tearing of first conductor 10, second conductor 20 and other components caused by the expansion of battery 50, prolonging the service life and further improving the adaptability to the environment. The above setting changes the direction of the external leading wire, thereby better adapting to and compatible with diversified and complex application conditions, and on the other hand, reduces the influence of the expansion of battery 50 on the conductor and other components, prolongs the service life, and overall meets the use requirements of various application scenarios.

[0029] For ease of illustration, the embodiment is described by taking the longitudinal vertical placement of battery 50 as an example, that is, as Figure 1 and 2 shown, the top end of battery 50 is the electrically connected end, the leading pole structure is located at the top end of battery 50, first conductor 10 is located at the top surface of battery 50, second conductor 20 extends to the longitudinal side of battery 50, and seat body 30 is also located at the longitudinal side of battery 50. Of course, the specific placement direction of battery 50 can be changed as needed, and when the direction of battery 50 is changed, the position of the leading pole structure is adjusted accordingly.

[0030] As Figure 1As shown, the first conductor and the second conductor 20 of the embodiment are both plate-shaped members, and the first conductor 10 is made of copper and the second conductor 20 is made of aluminum, of course, the specific shape and material can be adjusted as needed.

[0031] As shown, Figures 1 to 3 The specific number of the connecting segments can be set as needed, and the embodiment is taken as an example with four connecting segments, and the four connecting segments are connected by bending to form a three-bend structure. Specifically, the connecting segments include a first connecting segment 21, a second connecting segment 22, a third connecting segment 23, and a fourth connecting segment 24, wherein the first connecting segment 21 is in contact with the first conductor 10; the second connecting segment 22 is connected by bending with the first connecting segment 21 and extends away from the side surface of the battery 50; the side of the second connecting segment 22 away from the first connecting segment 21 is connected by bending with the third connecting segment 23, and the bending directions of the third connecting segment 23 and the first connecting segment 21 are opposite with respect to the second connecting segment 22; the side of the third connecting segment 23 away from the second connecting segment 22 is connected by bending with the fourth connecting segment 24, and the bending directions of the fourth connecting segment 24 and the second connecting segment 22 are opposite with respect to the third connecting segment 23. In this way, overall, the second conductor 20 of the embodiment is in the form of a structure in which the first connecting segment 21, the second connecting segment 22, the third connecting segment 23, and the fourth connecting segment 24 are sequentially connected by bending, and in the direction of extending out of the side surface of the battery 50, the bending directions are the same, bending from the end surface of the battery 50 to the middle region of the battery 50, so that the second conductor 20 can cooperate with the seat body 30 on the side surface of the battery 50 to realize the function of leading out the connection of the second conductor 20, and the second conductor 20 only occupies a small part of the space on the side surface of the battery 50, and the space above the upper end surface of the battery 50 is not occupied, on the contrary, the space above the battery 50 is reduced, thereby facilitating miniaturization.

[0032] As shown, Figure 1 and Figure 3 As shown, the first conductor 10 of the embodiment is laid horizontally on the top end surface of the battery 50, and the first connecting segment 21 is laid on the upper surface of the first conductor 10 and is in contact with the first conductor 10, in this way, the second conductor 20 is arranged horizontally, forming a structure in which the first connecting segment 21 and the third connecting segment 23 are parallel to the top end surface of the battery 50, and the second connecting segment 22 and the fourth connecting segment 24 are perpendicular to the top end surface of the battery 50, that is, the first connecting segment 21 and the third connecting segment 23 are arranged horizontally, and the second connecting segment 22 and the fourth connecting segment 24 are arranged vertically. The above structure makes the installation and arrangement between the second conductor 20 and the first conductor 10 relatively simple, and simplifies the processing technology.

[0033] As shown, Figures 2 to 4As shown, the fourth connecting section 24 is used for connecting with external lines, so the fourth connecting section 24 and the seat body 30 are provided with mounting holes 31 as mounting structures. Since the fourth connecting section 24 is longitudinally arranged, the longitudinal side of the seat body 30 is used as a mounting surface 33, so that the mounting surface 33 forms an angle with the end surface of the battery 50. The mounting surface 33 is longitudinally arranged, so that the mounting surface 33 is perpendicular to the end surface of the battery 50. The mounting holes 31 are arranged on the mounting surface 33, so that external fasteners such as connecting posts can be arranged in the mounting holes 31 and mounted on the seat body 30, thereby connecting the fourth connecting section 24 and the seat body 30 and realizing electrical connection between the fourth connecting section 24 and the seat body 30. Then, the second conductor 20 and the first conductor 10 are electrically connected with the battery 50, thereby realizing the conduction of the circuit. Of course, in addition to the mounting holes 31, other mounting structures such as mounting posts and buckles can also be used.

[0034] As shown, Figures 1 to 4 Since the second conductor 20 is three-folded, the seat body 30 is provided with a receiving recess 32 at the upper surface, which extends downward by a distance, so that at least one connecting section, i.e., the second connecting section 22 and the third connecting section 23 of the present embodiment, is accommodated in the receiving recess 32, thereby realizing the cooperation between the seat body 30 and the second conductor 20 and ensuring that the second conductor 20 can extend downward from the side of the battery 50.

[0035] As shown, Figure 3 and Figure 4As shown, since the second connecting section 22 extends longitudinally downward, and the third connecting section 23 extends transversely, the present embodiment is provided with two open sides, specifically, the accommodating recess 32 has adjacent first and second sides, both of which are open sides, the first side is the upper side of the accommodating recess 32, and the second side is the side of the accommodating recess 32 away from the battery 50, so that when the second connecting section 22 extends by bending, it can enter the accommodating recess 32 through the opening of the second side, and form the third connecting section 23 by transversely bending in the accommodating recess 32, the third connecting section 23 extends out of the accommodating recess 32 from the second side and downwardly bends to form the fourth connecting section 24, ensuring the close fit between the accommodating recess 32 and the second conductor 20, and the seat body 30 can also support the second conductor 20 to some extent, ensuring that the second conductor 20 can stably and reliably contact and cooperate with the first conductor 10, avoiding the situation that the second conductor 20 forms a cantilever structure and breaks. It should be noted that since the mounting surface 33 cooperates with the fourth connecting section 24, the mounting surface 33 is essentially located in the plane of the second side, that is, the mounting surface 33 is located below the second side of the accommodating recess 32, and the fourth connecting section 24 is the section of the second conductor 20 extending out of the accommodating recess 32, and the mounting surface 33 and the fourth connecting section 24 are provided with the aforementioned mounting hole 31 and other mounting structures for mounting and connecting, thereby realizing the connection and fixation with the fourth connecting section 24.

[0036] For the battery module, the battery 50 is provided with a plurality of batteries 50, and each battery 50 is stacked in sequence to form a battery module. The series and parallel connection between adjacent batteries is realized by connecting the positive and negative poles of adjacent batteries through busbars. The specific connection mode can be set according to the requirements. The first conductor 10 is located above the pole of the end battery of the plurality of batteries 50 and is electrically connected with the pole of the end battery, and is used to output the power of the entire battery module through the second conductor and other connection structures. The second conductor 20 can also be provided with only one, and the second conductor 20 can be arranged at the side surface of the outermost battery 50, that is, the second conductor 20 is arranged at the outer side surface of the end battery 50 along the arrangement direction of the battery 50, so that the arranged battery 50 can be connected to the outside as a whole through the first conductor 10 and the second conductor 20. Based on the above arrangement mode, since the second conductor 20 and the seat body 30 are arranged at the outer side surface of the end battery 50, the seat body 30 of the present embodiment further has a limiting protrusion 34. Since the mounting surface 33 is located on the side of the seat body 30 away from the battery 50, the limiting protrusion 34 is arranged at the mounting surface 33 and protrudes from the mounting surface 33, and the protruding distance of the limiting protrusion 34 is greater than the thickness of the fourth connecting section 24. In this way, when the battery 50 is packaged, the limiting protrusion 34 can directly abut and limit the end plate, so as to control the distance between the end plate and the second conductor 20 on the one hand, avoid the end plate from pressing the second conductor 20 and other components to affect the damage of the components, and on the other hand, the limiting protrusion 34 can abut the end plate, thereby avoiding displacement and ensuring the safety of the battery 50 during packaging.

[0037] As shown in FIGS. 3 and Figure 4 In the present embodiment, the lead-out pole structure further comprises a protective shell 40, which covers the outside of the seat body 30 and shields the second conductor 20. In order to further improve the protection of the second conductor 20, the present embodiment additionally provides a protective shell 40, which covers the side of the seat body 30 away from the battery 50, and the structure and part of the accommodating recess 32, the fourth connecting section 24, the mounting surface 33 and the like are all in the protective shell 40. In this way, the protective shell 40 can protect the component structure. Due to the arrangement of the protective shell 40, the component directly abutting the end plate is the protective shell 40, and the abutment between the limiting protrusion 34 and the end plate mainly plays the effect of avoiding displacement.

[0038] As shown in FIGS. 3 and Figure 4 and 5As shown, the embodiment is provided with a sliding rail structure 41 between the protective shell 40 and the seat body 30. In consideration of the convenience of installation, the sliding rail structure 41 can extend longitudinally or laterally, and the embodiment adopts the lateral extension arrangement. The reason for adopting lateral extension is that when a plurality of batteries 50 are arranged in sequence to form a battery module, the lateral movement of the protective shell 40 is limited by the end plate of the battery module, so that the protective shell 40 can be stably installed on the seat body 30, avoiding accidental falling. The sliding rail structure 41 of the embodiment adopts the mode of protrusion and sliding groove, wherein the protrusion is arranged on one of the seat body 30 and the protective shell 40, and the sliding groove is arranged on the other. In the embodiment, the lateral extension sliding groove is arranged at the outer side of the seat body 30, and the sliding groove can be provided with a plurality of protrusions arranged corresponding to the sliding groove. During installation, the protrusion is aligned with the sliding groove, and the protective shell 40 is moved laterally to cover the outer side of the accommodating recess 32 and the mounting surface 33, thereby achieving shielding protection of the second conductor 20.

[0039] As shown, Figure 4 The protective shell 40 of the embodiment adopts the structure of sequentially bending first and second sections, wherein the first section cooperates with the first side of the accommodating recess 32, and the second section cooperates with the second side of the accommodating recess 32 and the mounting surface 33, thereby achieving overall covering of the accommodating recess 32 and the mounting surface 33, and improving the protection effect. The second section can also be provided with an extension section, and the protrusion is arranged on the extension section to match the sliding groove. Of course, the protective shell 40 can also increase the covered parts as needed.

[0040] The embodiment also provides a battery module, which comprises a shell, a plurality of batteries 50 and the above-mentioned lead-out pole structure. The batteries 50 are arranged in sequence, and adjacent batteries 50 are connected through busbars. Along the arrangement direction of the batteries 50, the first conductor 10 is located above the end battery 50 and electrically connected with the pole of the end battery 50. The side surface of the end battery 50 is provided with the second conductor 20, which is conducive to reducing the cost and reducing the space occupation. At the same time, the limiting protrusion 34 of the lead-out pole structure is limited and abuts against the end plate of the battery module, thereby avoiding displacement.

[0041] It should be noted that the plurality in the above embodiment means at least two.

[0042] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0043] 1. The problem that the output pole of the battery module in the prior art cannot adapt to some use scenarios is solved.

[0044] 2. It can be applied to scenarios such as insufficient space above, thereby improving the adaptability of the lead-out pole structure to application scenarios and improving the applicable scenarios.

[0045] 3. The battery expansion can be absorbed by the displacement generated by the battery expansion, avoiding the battery expansion causing the first conductor, the second conductor and other components to be torn, prolonging the service life and further improving the adaptability to the environment.
