[0027] Please also refer to Figures 1-6This utility model provides a battery assembly structure with a sampling structure. The battery module 100 includes a plurality of batteries 13 arranged along a preset direction. A support plate 20 is provided on the top of the plurality of batteries 13. A signal acquisition component corresponding to each battery 13 is provided on the support plate 20. The signal acquisition component includes an acquisition board 31 and a signal harness 32 electrically connected to the acquisition board 31. Two first limiting parts 21 are provided on the top of the support plate 20 and are arranged opposite to each other. The two first limiting parts 21 form receiving grooves 22 between the two first limiting parts 21 and the support plate 20, respectively. The signal harness 32 is disposed in the receiving groove 22 adjacent to it.

[0028] In this embodiment, multiple batteries 13 are arranged sequentially in a preset direction to form a complete battery module 100 structure. A support plate 20 is provided on the top of the battery module 100. This support plate 20 not only provides mechanical support for the entire sampling structure, but also serves to install and fix each signal acquisition component.

[0029] Specifically, the support plate 20 is equipped with signal acquisition components corresponding to each battery 13. Each signal acquisition component includes two key parts: an acquisition board 31 and a signal harness 32 electrically connected to the acquisition board 31. The acquisition board 31 is mainly used to acquire the operating status information of the battery 13, including but not limited to parameters such as the voltage and current of the battery 13. The acquisition board 31 has reserved positive and negative electrode tabs for electrical connection with the battery 13. These electrode tabs are located on the bottom surface of the support plate 20, while the signal harness 32 is responsible for transmitting the signal data acquired by the acquisition board 31.

[0030] To achieve orderly arrangement and protection of the signal harness 32, two first limiting parts 21 are provided opposite to each other on the top of the support plate 20. These two first limiting parts 21 form receiving grooves 22 between themselves and the support plate 20. The first limiting parts 21 extend vertically upwards from the top surface of the support plate 20; therefore, one side (bottom) of the receiving groove 22 is the top surface of the support plate 20, and the other side is the outer wall surface of the first limiting parts 21. This structure forms a semi-enclosed space, which can effectively accommodate and protect the signal harness 32.

[0031] In practical implementation, since each battery 13 needs to be equipped with a data acquisition board 31 for status monitoring, multiple signal harnesses 32 will be formed. To ensure that these signal harnesses 32 are distributed in an orderly manner, two first limiting parts 21 are located on opposite sides of the top of the support plate 20, forming two spaces for arranging the harnesses. Each signal harness 32 is set in an adjacent receiving slot 22. This regional arrangement makes the harness routing clearer. At the same time, the structure of the receiving slot 22 also provides physical protection for the harnesses, preventing them from being damaged by external forces during use.

[0032] In this embodiment, "opposite arrangement" means that the two first limiting portions 21 are respectively arranged on opposite sides of the top of the support plate 20, that is, one is arranged on one side of the top of the support plate 20, and the other is arranged on the opposite side; the inner surfaces of the two first limiting portions 21 face each other. Specifically, the inner surface of one first limiting portion 21 faces the other first limiting portion 21, and the inner surface of the other first limiting portion 21 also faces the first first limiting portion 21.

[0033] This opposing structure creates a channel 25 between the two first limiting parts 21 for the subsequent installation of the isolation member 40. Meanwhile, the receiving groove 22 formed between each first limiting part 21 and the support plate 20 is located on both sides of this channel 25.

[0034] In this embodiment, the preset direction refers to the length direction of the battery module 100 container. For example, if the container is a cuboid, then the preset direction is the length direction of the cuboid.

[0035] In this embodiment, a pre-assembled installation method can be used to install the signal acquisition components. Specifically, before assembling the battery module 100, the operator can pre-fix the acquisition board 31 and its corresponding signal harness 32 onto the support plate 20. Each acquisition board 31 has its corresponding installation position, ensuring that its reserved tab interface corresponds to the positive and negative terminal interface positions of the battery 13 below. The signal harness 32 is fixed in the corresponding receiving slot 22 according to the preset wiring path to avoid displacement or tangling during later installation.

[0036] After the battery module 100 is assembled, the pre-assembled support plate 20 is placed on the battery module 100 and an electrical connection is established with the battery 13 through the reserved tab interface to complete the rapid installation of the signal acquisition component.

[0037] This pre-assembled installation method avoids the tedious process of installing each acquisition board 31 to each battery 13 and organizing the wiring harness, greatly shortening the installation time. Since the position of the acquisition components has been pre-adjusted and fixed, the acquisition board 31 can be accurately aligned with the connection position of the battery 13 when the support plate 20 is installed. Through the pre-fixing method, the installation position of each acquisition board 31 and the arrangement of the wiring harness can be carefully checked on the workbench to improve the accuracy and reliability of the installation, thereby reducing the complexity of on-site wiring and reducing the difficulty of construction and the possibility of errors. The pre-assembly process can be completed in a controlled environment, making it easier to ensure the installation quality.

[0038] This integrated installation solution not only simplifies on-site installation steps and improves assembly efficiency, but also ensures the standardization and reliability of the entire installation process. In later maintenance, repairs can be quickly completed by replacing the entire 20-unit support plate, greatly enhancing the maintainability of the device.

[0039] In one embodiment, the top of the support plate 20 is also provided with a plurality of second limiting parts 23, which are spaced apart along the arrangement direction of the battery 13; a wire harness channel is formed between two adjacent second limiting parts 23, which is used to accommodate the signal wire harness 32 of the adjacent acquisition board 31, and the wire harness channel is connected to the receiving groove 22.

[0040] In this embodiment, in addition to the first limiting part 21, the top of the support plate 20 is also provided with a plurality of second limiting parts 23. These second limiting parts 23 are spaced apart along the arrangement direction of the batteries 13. Specifically, the plurality of second limiting parts 23 are arranged sequentially at intervals in a manner consistent with the arrangement direction of the batteries 13 in the battery module 100. This makes it so that an independent wiring harness channel is formed between every two adjacent second limiting parts 23.

[0041] Each harness channel is specifically designed to accommodate the signal harness 32 connected to its adjacent acquisition board 31. Specifically, the harness channel formed between two adjacent second limiting parts 23 is used to arrange and fix the signal harness 32 of the corresponding acquisition board 31. The harness channel is connected to the receiving slot 22 formed by the first limiting part 21, allowing the signal harness 32 to be orderly led out through the harness channel and then enter the receiving slot 22 for centralized management. This through-flow design achieves a smooth transition of the signal harness 32 from the acquisition board 31 to the junction box, making the entire wiring more organized.

[0042] By arranging the second limiting part 23 at intervals, multiple independent wire harness channels are formed, and the signal wire harness 32 of each acquisition board 31 has its own dedicated arrangement space, avoiding the problem of wire harnesses of different acquisition boards 31 crossing or mixing with each other. This regional arrangement method makes the wire harness of each acquisition board 31 clearly identifiable, and the specific wire harness location can be quickly located during later maintenance or troubleshooting, improving maintenance efficiency. By fixing the signal wire harness 32 of each acquisition board 31 in the corresponding wire harness channel, the possibility of the signal wire harness 32 moving or loosening is reduced, thereby ensuring the stability of the wire harness during use.

[0043] In this embodiment, the second limiting part 23 is also formed by extending vertically upward from the top surface of the support plate 20, and each second limiting part 23 is perpendicular to the surface of the support plate 20.

[0044] This vertically extending design gives the wire harness channel formed between two adjacent second limiting parts 23 a clear boundary. The bottom side of the channel is the top surface of the supporting plate 20, and the sides are the inner walls of the second limiting parts 23, providing a stable accommodating space for the wire harness. At the same time, the vertically extending structure provides lateral physical protection for the wire harness, effectively preventing external forces from interfering with or damaging it. In addition, this vertically upward structure makes the installation and replacement of the wire harness more convenient, allowing maintenance personnel to work directly from the top.

[0045] In one embodiment, the top of the support plate 20 is also provided with a plurality of third limiting parts 24. The plurality of third limiting parts 24 respectively form a groove 241 for accommodating the acquisition plate 31 on the top of the support plate 20. The grooves 241 are spaced apart along the arrangement direction of the batteries 13 and are connected to the corresponding wire harness channel.

[0046] In this embodiment, a plurality of third limiting portions 24 are also provided on the top of the support plate 20. These third limiting portions 24 respectively form grooves 241 on the top of the support plate 20 for accommodating the acquisition plate 31, so that the acquisition plate 31 can be stably installed in a predetermined position. These grooves 241 are spaced apart along the arrangement direction of the batteries 13, and their arrangement direction is consistent with the arrangement direction of the batteries 13 in the battery module 100.

[0047] Each slot 241 is directly connected to its adjacent wiring harness channel. Specifically, when the acquisition board 31 is installed in the slot 241, the signal harness 32 connected to it can be laid out through the wiring harness channel and eventually extend into the receiving slot 22. This connection design achieves a seamless transition from the acquisition board 31 to the signal harness 32, facilitating the overall layout and management of the signal harness 32.

[0048] In practical applications, similar to the first limiting part 21 and the second limiting part 23, the third limiting part 24 also extends vertically upward from the top surface of the support plate 20, forming a groove 241 on the top surface of the support plate 20. The setting of the third limiting part 24 mainly considers the following aspects: First, by forming a groove 241 on the top of the support plate 20, a stable installation space is provided for the acquisition plate 31, preventing displacement of the acquisition plate 31 during installation and use; second, the spacing of the groove 241 ensures that each acquisition plate 31 can maintain the correct positional relationship with the corresponding battery 13.

[0049] In practice, the operator first inserts the acquisition board 31 into the corresponding slot 241, then arranges the signal harness 32 connected to the acquisition board 31 through the connected harness channel, and finally confirms that the installation positions of all acquisition boards 31 and harnesses are correct, thus completing the installation of all signal acquisition components on the support plate 20.

[0050] In this embodiment, the dimensions of each slot 241 are designed to match the external dimensions of the acquisition board 31; at the same time, the depth of the slot 241 is appropriate, which makes it easy for the operator to directly insert the acquisition board 31 into the slot 241 from the top for installation, and can also securely fix the acquisition board 31.

[0051] In one embodiment, a channel 25 is formed between the two first limiting parts 21, with the two ends connected. An isolation member 40 is provided in the channel 25, and an explosion-proof valve 14 is provided on the top of each of the multiple batteries 13. The explosion-proof valve 14 is located inside the isolation member 40.

[0052] In this embodiment, a channel 25 is formed between the two first limiting portions 21 at the top of the support plate 20, with their opposite ends connected. An isolator 40 is provided in the channel 25. This arrangement is mainly to meet the safety protection requirements of the battery module 100.

[0053] In the battery module 100, explosion-proof valves 14 are respectively installed on the top of multiple batteries 13, and these explosion-proof valves 14 are all located inside the isolation member 40. When a battery 13 experiences an abnormal situation and needs to be depressurized, the explosion-proof valves 14 can operate normally under the protection of the isolation member 40, avoiding the pressure relief process from affecting surrounding components.

[0054] The channel 25 is connected at both ends, which ensures the smooth discharge of gas during depressurization. At the same time, the structure of the channel 25 forms a partially enclosed space for the explosion-proof valve 14, effectively controlling the discharge direction of the depressurized gas. When depressurization is required, the isolation element 40 can guide the gas to be discharged safely in a predetermined direction.

[0055] In one embodiment, the isolation member 40 includes: a base plate 41 and vertical plates 42 disposed on opposite sides of the base plate 41, the vertical plates 42 and the base plate 41 forming an isolation groove 43; the base plate 41 is provided with a plurality of through grooves 411, the plurality of through grooves 411 are spaced apart along the arrangement direction of the batteries 13 and communicate with the isolation groove 43, and explosion-proof valves 14 are respectively disposed in the through grooves 411.

[0056] In this embodiment, the isolation member 40 includes a base plate 41 and vertical plates 42 disposed on opposite sides of the base plate 41. These vertical plates 42, together with the base plate 41, form an isolation groove 43. The base plate 41 contains a plurality of through slots 411, which are spaced apart along the arrangement direction of the batteries 13. Each through slot 411 is in communication with the isolation groove 43, forming a complete pressure relief channel. The explosion-proof valves 14 on the top of the batteries 13 are respectively disposed in these through slots 411, ensuring that each explosion-proof valve 14 can work normally when needed.

[0057] The base plate 41 serves as the basic support plane, and the through slot 411 provides the necessary space for the pressure relief channel; the vertical plate 42 forms a three-dimensional protective space, effectively preventing external debris from entering the pressure relief area; the spacing of the through slot 411 corresponds to the arrangement of the batteries 13, ensuring the orderly pressure relief and ensuring the smooth discharge of the pressure relief gas.

[0058] In one embodiment, the top ends of the vertical plates 42 extend toward the center of the isolation groove 43 to form support portions 44, and there are gaps between the support portions 44.

[0059] In this embodiment, the top ends of the vertical plates 42 extend towards the center of the isolation groove 43 to form support portions 44, with a certain gap maintained between these inwardly extending support portions 44. In this design, the support portions 44 extend horizontally from the top ends of the vertical plates 42 towards the center of the isolation groove 43, forming an inwardly tapered structure. The support portions 44 on both sides do not contact each other, but have a gap in the middle. The support portions 44 not only provide support for other components above them, but the gaps between them also provide the necessary space for the pressure relief channel.

[0060] In practical applications, this structural design mainly considers the following requirements: First, the support part 44 provides reliable support for other components that may be placed above it; second, the gap between the support parts 44 ensures the unobstructed flow of the pressure relief channel, allowing the pressure relief gas to flow in a predetermined direction and preventing the pressure relief gas from spreading directly to the surroundings; third, this partially enclosed structure can prevent external debris from entering without affecting the normal functioning of the pressure relief function.

[0061] In one embodiment, two battery modules 100 are provided, namely a first battery module 11 and a second battery module 100 that are adjacent in the horizontal direction.

[0062] In this embodiment, the battery module 100 adopts a dual-module design, specifically including two independent battery modules 100: a first battery module 11 and a second battery module 100. These two battery modules 100 are arranged adjacent to each other in the horizontal direction.

[0063] Specifically, the first battery module 11 and the second battery module 100 are installed in a horizontally adjacent relationship with an appropriate spacing between them. Each battery module 100 is equipped with an independent support plate 20 and a corresponding signal acquisition component to ensure that each can be monitored independently.

[0064] In one embodiment, insulating seats 50 are respectively provided at both ends of the first battery module 11 and the second battery module 100. The insulating seats 50 at one end of the first battery module 11 and the second battery module 100 are fixedly connected to the corresponding acquisition board 31. The acquisition board 31 is electrically connected to the corresponding positive line 61 and the negative line 62. The insulating seats 50 at the other end of the first battery module 11 and the second battery module 100 are fixedly connected to another corresponding acquisition board 31 through a connecting plate 70.

[0065] In this embodiment, insulating bases 50 are respectively provided at both ends of the first battery module 11 and the second battery module 100. Specifically, the electrical connections at the ends of the first battery module 11 and the second battery module 100 adopt different connection methods: at one end, the insulating base 50 is fixedly connected to the corresponding acquisition board 31, and these acquisition boards 31 are further connected to the corresponding positive line 61 and negative line 62; at the other end, the insulating base 50 is connected to another corresponding acquisition board 31, which is fixedly connected through the connecting plate 70 between the first battery module 11 and the second battery module 100.

[0066] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
