[0022] It should be noted that the embodiments in the present application and the features in the embodiments 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.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0024] In the present application, unless otherwise stated, the orientation words such as "up, down, 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 each component, but the above orientation words are not used to limit the present application.

[0025] In order to solve the problem of complex installation and fixing structure of the battery module wire harness connector in the prior art, the present application provides a battery end plate, a battery module and a battery pack.

[0026] As Figures 1 to 3 shown, a battery end plate of the present embodiment includes: an end plate body 10, an extension 20 and a protective cover 30, the extension 20 is located at the side of the end plate body 10 and forms a containing groove 23 for containing components between the side of the end plate body 10; the protective cover 30 is movably connected with the end plate body 10 or the extension 20 and can be arranged on the opening side of the containing groove 23 to shield the components.

[0027] The embodiment is characterized in that the extension part 20 is arranged at the side of the end plate body 10, and the accommodation groove 23 is formed between the extension part 20 and the end plate body 10, so that the wire harness connector and other components of the battery module can be placed in the accommodation groove 23, and the accommodation groove 23 is used for clamping and fixing the wire harness connector in the battery module, thereby achieving the installation and fixation of the wire harness connector. Since the extension part 20 is arranged at the side of the end plate body 10, additional structures are not needed to achieve the installation of the wire harness connector, so that the structure of the battery end plate is more simple, and quick assembly can still be achieved when facing various forms of wire harness connectors. At the same time, the protective cover 30 is arranged at the opening of the accommodation groove 23, which shields the wire harness connector inside the accommodation groove 23, prevents it from being affected by external environmental factors, and thus achieves the protection of the wire harness connector. The above arrangement can not only save additional installation structures and reduce the demand for additional structural parts, thereby reducing the complexity of the structure and the assembly difficulty, reducing the material use cost, but also ensures the safety of the wire harness connector and the wire harness in the battery module, avoids damage to the electrical connection by external environmental factors, improves the safety and reliability of the battery module, and also improves the utilization rate of the internal space of the battery module and the overall performance of the battery module.

[0028] The embodiment takes the wire harness connector placed in the accommodation groove 23 as an example for description, and of course, other components can also be installed as needed.

[0029] The extension part 20 extends upward at the placement position of the wire harness connector to form the protective cover 30, which is movably connected with the extension part 20. That is, the protective cover 30 is designed as a flip structure, that is, the protective cover 30 can be folded downward to cover the opening side of the accommodation groove 23, so as to effectively protect the wire harness connector in the accommodation groove 23, and when the wire harness and the connector are not needed to be operated, the protective cover 30 can be flipped to close, without occupying additional space.

[0030] As shown in Figures 1 to 3 In the embodiment, the battery end plate further comprises a limiting part 11 located at the inner wall of the accommodation groove 23 and capable of limiting cooperation with the component. That is, when the wire harness connector is placed in the accommodation groove 23, it can be installed in limiting cooperation with the limiting part 11, so that the position of the wire harness connector in the accommodation groove 23 is ensured to be stable by the limiting part 11, the displacement caused by vibration or impact is reduced, and the position of the component in the battery module is ensured to be stable to avoid accidental disengagement.

[0031] Optionally, the structure of the limiting part 11 can be a protruding limiting structure, that is, a protrusion is arranged on the inner wall of the accommodating groove 23. When the wire harness connector is clamped into the accommodating groove 23, the protrusion can be clamped and matched with the wire harness connector to limit the displacement of the wire harness connector in the direction of being pulled out of the accommodating groove 23. The structure of the protrusion is simple, and it is also convenient for the installation and disassembly of the wire harness connector, so that the maintenance or replacement of the wire harness connector is more convenient, and the maintenance time and cost are reduced. In addition to the structure of the protrusion, the limiting part 11 can also adopt a groove limiting structure, that is, a groove is arranged on the inner wall of the accommodating groove 23. A part of the wire harness connector can be embedded in the groove to form a limiting fit to prevent the displacement of the wire harness connector in the direction of being pulled out. Of course, the limiting part 11 can also adopt other clamping and matching modes, such as interference fit and the like.

[0032] As shown in Figures 2 to 3 In the present embodiment, the protruding part 20 includes a first segment 21 and a second segment 22, both of which are arranged apart from the side surface of the end plate body 10, so as to form different functional areas. Specifically, the second segment 22 forms an accommodating groove 23 with the side surface of the end plate body 10, which is used for fixing and protecting key electrical components such as wire harness connectors; and the first segment 21 forms a wire slot 24 with the side surface of the end plate body 10, which is used for the wiring and orderly arrangement of the wire harness, so as to avoid the confusion or interference between the wire harness and other components, and also facilitate the combing and maintenance of the wire harness. By integrating different functional areas on the same end plate, on the one hand, the management of the wire harness and related electrical components is more centralized and efficient; on the other hand, the design of the wire slot 24 can ensure the order and safety of the wire harness inside the battery module, avoid the short circuit risk between the wire harness and the electrical components, and improve the safety and reliability of the battery module.

[0033] The first segment 21 and the second segment 22 of the present embodiment are arranged in a substantially parallel manner with the side surface of the end plate body 10. Since the thicknesses of the first segment 21 and the second segment 22 of the present embodiment are not large, there is a certain distance between the end portions of the first segment 21 and the second segment 22. Therefore, the protruding part 20 of the present embodiment also substantially includes a transition segment, which is located between the first segment 21 and the second segment 22, so as to connect the first segment 21 and the second segment 22 together. The connection between the first segment 21 and the transition segment and the connection between the second segment 22 and the transition segment can adopt a bending connection form, so as to form a multi-segment form. Of course, in addition to the arrangement of the transition segment, the thickness of the first segment 21 or the second segment 22 can be arranged to be larger, so that the first segment 21 and the second segment 22 can be directly connected together.

[0034] As shown in Figures 2 to 3As shown, in the embodiment, the second distance between the second section 22 and the side of the end plate body 10 is greater than the first distance between the first section 21 and the side of the end plate body 10. That is, the two sections have different distances from the side of the end plate body 10. The above arrangement is made in consideration of the fact that the harness connector is larger than the high-voltage harness. Therefore, the width of the accommodating groove 23 formed by the second section 22 is greater than the width of the wire slot 24 formed by the first section 21. On the one hand, the wire slot 24 formed by the first section 21 and the end plate body 10 can meet the needs of the harness arrangement, and the harness is constrained in the narrow wire slot 24, which provides a clear path and appropriate protection for the arrangement of the harness, and is more convenient for the arrangement of the wire. On the other hand, the wider design of the second section 22 provides sufficient space for the placement of the harness connector. In addition, the different widths of the first section 21 and the second section 22 also avoid the interference between the harness and the harness connector. The above-mentioned width refers to the distance between the inner wall of the extension 20 and the side of the end plate body 10.

[0035] As shown in the drawings, Figures 2 to 3 In the embodiment, the first section 21 is provided with a plurality of first sections 21 on the two opposite sides of the second section 22. Specifically, the extension 20 of the embodiment includes two first sections 21 and one second section 22. The two first sections 21 are respectively arranged on the two sides of the second section 22, so that the side of the extension 20 forms a three-section structure. In this way, the wire slot 24 can be formed at both ends of the accommodating groove 23, thereby providing more path options for the arrangement of the harness, so that the harness can be arranged flexibly according to specific needs, thereby improving the assembly efficiency of the battery module and the convenience of harness management. Of course, the number of first sections 21 and second sections 22 can be determined according to the layout requirements of the actual battery module and the number of harnesses and harness connectors.

[0036] In the embodiment, the first section 21 can also be provided with a harness fixing hole. When the harness is accommodated in the wire slot 24, the harness can be fixed by a cable tie passing through the harness fixing hole, or the harness outside the wire slot 24 can be fixed by a cable tie.

[0037] Based on the above structure, the side of the extension 20 of the embodiment has a structure of one first section 21, one transition section, a second section 22, another transition section, and another first section 21. In this way, the middle accommodating groove 23 is used to install the harness connector, and the wire slots 24 at both ends are used to place the harness, thereby achieving the installation and fixation of the components and the harness. In the embodiment, the protective cover 30 is only arranged at the opening side of the accommodating groove 23, and the protective cover 30 is not arranged at the opening side of the wire slot 24. Of course, the protective cover 30 can also be arranged at the opening side of the wire slot 24. Figures 2 to 3As shown, in the embodiment, the top surface opening of the accommodating groove 23 is provided and formed with an opening side, so that the wire harness connector can be placed or taken out from above, which is more convenient for the installation and maintenance of the wire harness connector. The protective cover 30 is reversibly arranged at the opening side. For example, the connection mode of the protective cover 30 can be a hinge connection, which is installed at the opening side. When the wire harness connector needs to be maintained, the protective cover 30 can be opened by turning over, so as to facilitate the inspection and operation of the wire harness connector in the accommodating groove 23; when the wire harness connector does not need to be maintained or inspected, the protective cover 30 can be closed by turning over, covering the opening of the accommodating groove 23. In this way, on the one hand, the external environment can be effectively isolated, the wire harness connector is protected from mechanical impact and other external factors, and the safety and reliability of the wire harness connector are improved. On the other hand, the protective cover 30 is directly arranged at the opening side of the accommodating groove 23, without the need for additional installation space, which optimizes the space layout inside the battery module and improves the space utilization rate.

[0038] As shown, Figures 1 to 3 As shown, in the embodiment, the battery end plate further comprises a locking structure 40 for stably fixing the protective cover 30 on the end plate body 10. The locking structure 40 is located between the protective cover 30 and the end plate body 10. Specifically, the locking structure 40 is located on the contact surface between the protective cover 30 and the end plate body 10. When the protective cover 30 is arranged on the accommodating groove 23, the corresponding position of the protective cover 30 can be limited by the locking structure 40 on the side surface of the end plate body 10, so as to ensure the stability of the protective cover 30 during use, avoid the damage of the wire harness connector due to the loosening of the protective cover 30, and improve the safety and reliability of the battery module. When the related components need to be maintained, the operator can loosen the locking structure 40 at any time, so that the protective cover 30 can be opened in turn, so as to facilitate the inspection and maintenance of the related components, improve the maintainability and maintenance efficiency of the battery module, and reduce the maintenance cost.

[0039] Optionally, the locking structure 40 comprises at least one of a buckle structure, a magnetic attraction structure, and an adhesive structure. When the locking structure 40 is a magnetic attraction structure, the magnetic attraction structure can use the attractive force between magnets to fix the protective cover 30. Specifically, magnets can be arranged on the end plate body 10 and the protective cover 30, respectively. When the protective cover 30 is closed, the magnets can automatically attract and fix the protective cover 30 in place through the attractive force. When the protective cover 30 is opened, an external force can easily separate the protective cover 30 from the end plate body 10. On the one hand, using the magnetic attraction structure ensures the convenience of operation and improves the maintainability of the battery module. On the other hand, because the magnetic attraction structure is a non-clamping type of installation method, it also avoids the risk of damage such as structural wear or breakage that may be caused by traditional clamping locking structures 40. When the locking structure 40 is an adhesive structure, the adhesive structure uses an adhesive or an adhesive tape to form a physical fit between the protective cover 30 and the end plate body 10 and thereby connect them. Specifically, reusable adhesive parts can be arranged at corresponding positions of the protective cover 30 and the end plate body 10. The adhesive parts can be separated and connected when the protective cover 30 is opened and closed, and the adhesive parts can also be reused, thereby additionally increasing the sealing effect while being fixed. The locking structure 40 in the present embodiment is a buckle structure. Specifically, a lock buckle structure is arranged at a corresponding position of the protective cover 30, and a lock groove structure is arranged at a corresponding position of the end plate body 10. When the protective cover 30 is closed, the lock buckle structure can be clamped into the lock groove structure, forming a mechanical lock to ensure that the protective cover 30 will not be accidentally opened during normal use or transportation of the battery module. Using the buckle structure, on the one hand, the buckle structure ensures the stability and durability of the locking of the protective cover 30 and the end plate body 10; on the other hand, the buckle structure is easier to operate and facilitates quick disassembly and assembly. Of course, the number of lock buckle structures and the number of lock groove structures can be set according to requirements. Optionally, the forms can be one lock buckle structure corresponding to one lock groove structure, multiple lock buckle structures corresponding to one lock groove structure, or multiple lock buckle structures one-to-one corresponding to multiple lock groove structures. In the present embodiment, the form is one lock buckle structure corresponding to one lock groove structure, which is not limited in the present embodiment.

[0040] As Figures 2 to 3As shown, in the embodiment, the protruding part 20 includes a bottom part and a side part connected by bending, which is different from the first segment 21 and the second segment 22 described above, and the bottom part and the side part are relative to the whole protruding part 20, while the first segment 21 and the second segment 22 are essentially the structure of the side part. The bottom part and the side part of the embodiment are arranged substantially perpendicular to each other, so as to form an L-shaped structure, in which the bottom part is connected with the top side of the end plate body 10 and serves as an intermediate transition, the bottom part forms the bottom part of the accommodation groove 23 and the wire groove 24, and the side part is spaced from the side of the end plate body 10 and forms the side part of the accommodation groove 23 and the wire groove 24. In this way, based on the structure described above, the whole protruding part 20 of the embodiment is divided into two parts, the bottom part and the side part, and the side part is divided into the first segment 21 and the second segment 22 along the length direction of the side part. Since the accommodation groove 23 and the wire groove 24 of the embodiment are in the form of opening upward, the bottom end of the side part is connected with the bottom part, the whole side part extends upward by a small distance, and protrudes as little as possible above the end plate body 10, and the side part and the bottom part are transversely extended for a long distance, so as to realize the accommodation and placement of the wire harness connector and the high-voltage wire harness. The above arrangement is helpful for the structural strength of the whole battery end plate, can provide more stable protection for the wire harness connector, and on the other hand, provides a stable accommodation space for the wire harness connector without increasing the overall volume of the end plate, avoids the use of additional structural parts, simplifies the assembly process, and improves the space utilization.

[0041] As shown, Figures 1 to 3 As shown, in the embodiment, the end plate body 10 has a first side 12 facing the battery cell and a second side 13 away from the battery cell, specifically, the first side 12 of the end plate body 10 facing the battery cell is in a planar structure for directly contacting and supporting the battery cell, and the second side 13 away from the battery cell is provided with a protruding grid structure, which is more resistant to deformation caused by external force extrusion due to its greater strength. The longitudinal section of the end plate body 10 is in a structure of wide at the top and narrow at the bottom, so that the end plate body 10 is easier to install or remove between the battery cell and the inner wall of the battery box, facilitating installation and removal. The protruding part 20 of the embodiment is located at the second side 13 and forms the accommodation groove 23 with the second side 13, so that the arrangement of the protruding part 20 does not affect the cooperation between the end plate body 10 and the battery cell, thereby ensuring that the end plate body 10 can still stably and reliably play its role on the basis of realizing the installation and fixation of the wire harness connector and the high-voltage wire harness, so that the whole battery end plate realizes the increase of functions without affecting the original functions.

[0042] The embodiment also provides a battery module comprising the battery end plate provided by any of the above embodiments and a battery.

[0043] The embodiment also provides a battery pack, which comprises the wire harness connector and the battery end plate, and the wire harness connector is arranged in the accommodating groove 23 of the battery end plate. Other structures such as batteries are also included in the battery pack, and details can be referred to the prior art, and the embodiment of the application will not be described herein. By adding the accommodating groove 23 and the protective cover 30 on the end plate, on the one hand, the additional injection molding part for placing the wire harness and the wire harness connector is omitted, the space inside the battery module is saved, on the other hand, the high-voltage wire harness and the wire harness connector are effectively protected and hidden, not only the overall appearance of the battery pack is improved, but also the service life and safety of the wire harness connector are improved, and the maintenance cost is reduced.

[0044] It should be noted that the plurality in the above embodiment means at least two.

[0045] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0046] 1. The problem of complex installation and fixing structure of the wire harness connector of the battery module in the prior art is solved.
