[0028] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0029] Please also refer to Figures 1-6 The present invention provides a battery sampling assembly structure, comprising: a support plate 10, a plurality of signal acquisition components disposed on the top of the support plate 10, the signal acquisition components including an acquisition plate 21 and a signal harness 22 electrically connected to the acquisition plate 21, two opposing first limiting parts 11 disposed on the top of the support plate 10, the two first limiting parts 11 forming receiving grooves 12 between the two first limiting parts 11 and the support plate 10 respectively, and the signal harness 22 disposed in the receiving groove 12 adjacent to it.

[0030] In this embodiment, the acquisition board 21 is mainly used to acquire the operating status information of the battery 81, including but not limited to parameters such as the voltage and current of the battery 81. The signal harness 22 is responsible for transmitting the signal data acquired by the acquisition board 21. The acquisition board 21 has reserved positive and negative electrode tab interfaces for electrical connection with the battery 81. These electrode tab interfaces actually pass through the bottom of the support plate 10, so that the acquisition board 21 can be electrically connected to the corresponding battery 81 when the support plate 10 is placed on the battery module 80.

[0031] Specifically, the top of the support plate 10 is provided with two first limiting portions 11 facing each other. "Facing each other" means that one is located on one side of the top of the support plate 10, and the other is located on the opposite side. The inner surfaces of the two first limiting portions 11 face each other; specifically, the inner surface of one first limiting portion 11 faces the other first limiting portion 11, and the inner surface of the other first limiting portion 11 also faces the first first limiting portion 11.

[0032] The first limiting part 11 extends vertically upward from the top surface of the support plate 10, and a receiving groove 12 is formed between each first limiting part 11 and the support plate 10. One side (bottom) of the receiving groove 12 is the top surface of the support plate 10, and the other side is the outer wall surface of the first limiting part 11. This structure forms a semi-enclosed space, which can effectively accommodate and protect the signal harness 22. The signal harness 22 is arranged in the adjacent receiving groove 12, and this regional arrangement makes the wiring path clearer. At the same time, the structure of the receiving groove 12 also provides physical protection for the wiring harness, preventing it from being damaged by external forces during use.

[0033] In practical implementation, since each battery 81 needs to be equipped with a data acquisition board 21 for status monitoring, multiple signal harnesses 22 will be formed. To ensure that these signal harnesses 22 are distributed in an orderly manner, two first limiting parts 11 are located on opposite sides of the top of the support plate 10, forming two spaces for arranging the harnesses. This structural design not only facilitates the arrangement and maintenance of the signal harnesses 22, but also effectively prevents mutual interference between different signal harnesses 22.

[0034] In one embodiment, the top of the support plate 10 is also provided with a plurality of second limiting parts 13, the plurality of second limiting parts 13 are spaced apart along a preset direction, and a wire harness channel 14 for accommodating the signal wire harness 22 is formed between two adjacent second limiting parts 13, and the wire harness channel 14 is connected to the accommodating groove 12.

[0035] In this embodiment, these second limiting portions 13 are arranged sequentially at intervals in a manner consistent with the arrangement direction (i.e., the preset direction) of the batteries 81 in the battery module 80. This results in an independent wiring harness channel 14 being formed between every two adjacent second limiting portions 13.

[0036] Each harness channel 14 is specifically designed to accommodate the signal harness 22 connected to its adjacent acquisition board 21. Specifically, the harness channel 14 formed between two adjacent second limiting parts 13 is used to arrange and fix the signal harness 22 of the corresponding acquisition board 21. The harness channel 14 is connected to the receiving slot 12 formed by the first limiting part 11, allowing the signal harness 22 to be orderly led out through the harness channel 14 and then enter the receiving slot 12 for centralized management. This through-flow design achieves a smooth transition of the signal harness 22 from the acquisition board 21 to the junction box, making the entire wiring more organized.

[0037] In this embodiment, the second limiting portion 13 also extends vertically upward from the top surface of the support plate 10, and each second limiting portion 13 is perpendicular to the surface of the support plate 10. This vertical extension arrangement ensures that the wire harness channel 14 formed between two adjacent second limiting portions 13 has a clear boundary. The bottom side of the wire harness channel 14 is the top surface of the support plate 10, and the two sides are the inner wall surfaces of the second limiting portions 13, providing a stable accommodating space for the wire harness. In addition, this vertical upward structure makes the installation and replacement of the wire harness more convenient, and maintenance personnel can work directly from the top.

[0038] By arranging the second limiting parts 13 at intervals, multiple independent wire harness channels 14 are formed. Each acquisition board 21's signal harness 22 has its own dedicated arrangement space, avoiding the problem of wire harnesses from different acquisition boards 21 crossing or mixing with each other. By fixing the signal harness 22 of each acquisition board 21 within its corresponding wire harness channel 14, the possibility of the signal harness 22 moving or loosening is reduced, thereby ensuring the stability of the wire harness during installation and use.

[0039] In one embodiment, the top of the support plate 10 is also provided with a plurality of third limiting parts 15. The plurality of third limiting parts 15 respectively form a groove 16 for accommodating the acquisition plate 21 on the top of the support plate 10. The grooves 16 are spaced apart along a preset direction and are connected to the corresponding wire harness channel 14.

[0040] In this embodiment, these slots 16 are arranged at intervals, and their arrangement direction is consistent with the arrangement direction of the batteries 81 in the battery module 80. Each slot 16 is directly connected to its adjacent wiring harness channel 14. Specifically, when the acquisition board 21 is installed in the slot 16, the signal harness 22 connected to it can be laid through the wiring harness channel 14 and eventually extend into the receiving slot 12. This connection design realizes a seamless transition from the acquisition board 21 to the signal harness 22, which facilitates the overall arrangement and management of the signal harness 22.

[0041] In this embodiment, similar to the first limiting part 11 and the second limiting part 13, the third limiting part 15 also extends vertically upward from the top surface of the support plate 10, forming a groove 16 on the top surface of the support plate 10. The dimensions of each groove 16 are designed to match the external dimensions of the acquisition plate 21. Simultaneously, the depth of the groove 16 is appropriately designed, facilitating the operator to directly insert the acquisition plate 21 into the groove 16 from the top for installation, while also ensuring a stable fixation of the acquisition plate 21.

[0042] In practice, the operator first inserts the acquisition board 21 into the corresponding slot 16, then arranges the signal harness 22 connected to the acquisition board 21 through the connected harness channel 14, and finally confirms that the installation positions of all acquisition boards 21 and harnesses are correct, thus completing the installation of all signal acquisition components on the support plate 10.

[0043] In one embodiment, a channel 111 is formed between the two first limiting parts 11, and an isolation member 30 is provided in the channel 111. An isolation groove 31 is provided between the opposite ends of the isolation member 30. A plurality of through holes 32 are provided on the bottom surface of the isolation member 30. The plurality of through holes 32 are used to accommodate the explosion-proof valve 82 of the battery 81 respectively. The plurality of through holes 32 are connected to the isolation groove 31.

[0044] In this embodiment, a channel 111 is formed between the two first limiting portions 11, with their opposite ends connected. An isolator 30 is disposed within the channel 111. This arrangement is primarily to meet the safety protection requirements of the battery module 80. The isolator 30 is disposed within the channel 111 formed between the two first limiting portions 11, with an isolation groove 31 between its opposite ends. Multiple through holes 32 are provided on the bottom surface of the isolator 30. These through holes 32 are mainly used to accommodate the explosion-proof valve 82 of the battery 81, and the multiple through holes 32 are connected to the isolation groove 31.

[0045] In the battery module 80, multiple batteries 81 are each equipped with an explosion-proof valve 82 on their tops, all located inside the isolation member 30. When a battery 81 experiences an abnormal situation requiring pressure relief, the explosion-proof valve 82 can operate normally under the protection of the isolation member 30, preventing the pressure relief process from affecting surrounding components. The channel 111 remains connected at both ends, a design that ensures smooth gas discharge during pressure relief.

[0046] In one embodiment, the isolation member 30 includes: a base plate 33 and vertical plates 34 disposed on opposite sides of the base plate 33. The vertical plates 34 and the base plate 33 form an isolation groove 31. A plurality of through holes 32 are disposed at intervals along a preset direction on the bottom surface of the base plate 33 and communicate with the isolation groove 31.

[0047] In this embodiment, the vertical plate 34 and the bottom plate 33 together form an isolation groove 31. The bottom plate 33 includes a plurality of through holes 32, which are spaced apart along the arrangement direction (i.e., the preset direction) of the batteries 81. Each through hole 32 is connected to the isolation groove 31, forming a complete pressure relief channel. The explosion-proof valves 82 on the top of the batteries 81 are respectively disposed in these through holes 32, ensuring that each explosion-proof valve 82 can work normally when needed.

[0048] The vertical plate 34 forms a three-dimensional protective space, effectively preventing external debris from entering the pressure relief area; it provides a directional channel for the pressure relief gas; together with the bottom plate 33, it forms the isolation groove 31, creating a complete pressure relief protection structure.

[0049] Through this structural design, the isolator 30 can not only effectively protect the normal operation of the explosion-proof valve 82, but also effectively control and guide the pressure relief process.

[0050] In one embodiment, the top ends of the vertical plates 34 extend toward the center of the isolation groove 31 to form support portions 35, and there is a gap between the oppositely arranged support portions 35.

[0051] In this embodiment, the support portion 35 extends horizontally from the top of the vertical plate 34 towards the center of the isolation groove 31, forming an inwardly recessed structure. The support portions 35 on both sides do not contact each other, but leave a gap in the middle. This creates a partially enclosed space, which protects the internal structure without affecting the pressure relief function.

[0052] In one embodiment, the plurality of signal acquisition components include a first part of signal acquisition components and a second part of signal acquisition components, and two first limiting parts 11 are disposed between the first part of signal acquisition components and the second part of signal acquisition components.

[0053] In this embodiment, this structural arrangement divides the signal acquisition component into two parts, one part corresponding to the positive terminal interface of the battery 81 in the battery module 80, and the other part corresponding to the negative terminal interface of the battery 81 in the battery module 80. The receiving groove 12 formed between the two first limiting parts 11 not only serves to house and protect the signal harness 22, but also achieves the orderly arrangement of the signal harness 22. Through this structural design, the signal harness 22 of each part of the signal acquisition component can be properly placed in the corresponding receiving groove 12, avoiding the problems of harness confusion and tangling.

[0054] In one embodiment, support plates 40 are respectively provided at opposite ends of the support plate 10, and slots 41 are provided at the top of the support plates 40, with insulating seats 50 provided inside the slots 41.

[0055] In this embodiment, the supporting vertical plate 40 is mainly fixedly connected to the housing structure to install the insulating base 50. The housing structure here refers to the mounting housing of the battery module 80. Each supporting vertical plate 40 has a slot 41 at its top, designed to support and fix the insulating base 50. The insulating base 50 matches the shape of the slot 41, allowing it to be directly inserted into and fixedly connected to it. The insulating base 50 is connected to the corresponding acquisition plate 21, with one end connected to the main positive line 61 and the main negative line 62, and the other end fixedly connected via a connecting plate 70 between the two battery modules 80.

[0056] In this embodiment, a support plate 10 is provided on the top of each of the two battery modules 80, and a connecting plate 70 is provided between the two battery modules 80. The two ends of the connecting plate 70 are respectively connected to the insulating base 50 to serve as an electrical connection between the two battery modules 80.

[0057] In one embodiment, the slot 41 includes a communicating upper opening 42 and a lower receiving cavity 43. The width of the upper opening 42 is smaller than the width of the lower receiving cavity 43. The insulating seat 50 includes a connected head 51 and a fixing part 52. The width of the head 51 is smaller than the width of the fixing part 52. The head 51 passes through the upper opening 42, and the fixing part 52 is received in the lower receiving cavity 43. There is a height difference between the fixing part 52 and the lower receiving cavity 43.

[0058] In this embodiment, the slot 41 adopts a stepped structure design, including a connected upper opening 42 and a lower receiving cavity 43, wherein the width of the upper opening 42 is smaller than the width of the lower receiving cavity 43. Correspondingly, the insulating base 50 also adopts a matching structure, including a connected head 51 and a fixing part 52, wherein the width of the head 51 is smaller than the width of the fixing part 52. During installation, the head 51 passes through the upper opening 42, and the fixing part 52 is received in the lower receiving cavity 43.

[0059] In practical implementation, the narrower design of the upper opening 42 guides the head 51 of the insulating base 50 to be accurately inserted, while the wider design of the lower receiving cavity 43 provides suitable installation space for the fixing part 52. During installation, the insulating base 50 is inserted into the slot 41 from front to back. After the fixing part 52 is fully inserted into the lower receiving cavity 43, a certain gap (i.e., height difference) will remain between its top surface and the lower receiving cavity 43. This gap is designed to ensure that the fixing part 52 has a certain vertical movement space after insertion, thereby accommodating positional changes of the support plate 10 and its signal acquisition components caused by various factors, improving the overall installation flexibility and adaptability.

[0060] 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.
