[0003] In order to solve the above problems, a bracket is arranged on the battery cell, and a groove is arranged on the bracket so that the pressure collection wire harness and the thermocouple wire harness can be placed in the groove; then a cover plate is arranged on the groove so that the pressure collection wire harness and the thermocouple wire harness can be limited and fixed between the groove and the cover plate, so as to avoid the heat generated by the battery cell affecting the wire harness and limit the movement of the wire harness.

[0004] Among them, in order to ensure that the collected signals of the pressure collection harness and the thermocouple harness are more accurate, an electromagnetic shielding layer is usually provided on the outside of the pressure collection harness and the thermocouple harness; however, since the pressure collection harness and the thermocouple harness themselves are relatively thin, they do not need to occupy much space in the groove. When an electromagnetic shielding layer is provided on the outside of the pressure collection harness and the thermocouple harness, the harness will become thicker and need to occupy a larger space in the groove; and it is time-consuming and labor-intensive to provide an electromagnetic shielding layer on the outside of each harness, and the cost is high.

That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features. Throughout the specification, the same reference numerals indicate the same elements.

[0038] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0039] like Figures 1 to 3 As shown, in this embodiment, a wiring harness structure and a battery module including the wiring harness structure are proposed. The battery module also includes a conductive bar 4, a wiring harness, and a plurality of battery cells 3 arranged in parallel. The wiring harness structure is arranged on the plurality of battery cells 3. The conductive bar 4 is arranged on the wiring harness structure and contacts the battery cells 3 with its surface, so that the conductive bar 4 is electrically connected to the battery cells 3. One end of the wiring harness is connected to the conductive bar 4, and the other end of the wiring harness is accommodated in the wiring harness structure. The wiring harness is used to collect the working parameters of the battery cells 3, such as temperature and voltage working parameters. That is, the wiring harness structure is used to accommodate the wiring harness for collecting the working parameters of the battery cells 3, which is conducive to the unified routing management of the wiring harness. The battery module in this embodiment can be a sodium battery module, and the specific type of the battery module is not limited here.

[0040] like Figure 1 and Figure 2 As shown, the conductive bar 4 includes a connecting bar 42 and an output bar 41, which are arranged on the wiring harness structure relatively to each other. The wiring harness of the connecting bar 42 and the wiring harness of the output bar 41 can be a thinner pressure collection wiring harness and a thermocouple wiring harness, respectively, so that the voltage and temperature of the battery cell 3 can be collected through the pressure collection wiring harness and the thermocouple wiring harness, respectively, so as to monitor the working state of the battery cell 3 in real time. Among them, the connecting bar 42 and the output bar 41 can be copper bars or aluminum bars, which are not specifically limited here.

[0041] It is worth noting that the improvement in this embodiment focuses on the wiring harness structure. The structure of the battery cell 3, the conductive bar 4 and the specific connection structure therebetween are not described in detail here, and reference may be made to the structure of the existing battery module.

[0042] Specifically, Figures 1 to 4 As shown, the wiring harness structure includes a bracket 1 and a cover plate 2; wherein the bracket 1 is configured to be arranged on each battery cell 3, and a groove 11 is provided on the bracket 1, and the length of the groove 11 extends along the length direction of the bracket 1, and the groove 11 is used to accommodate the wiring harness electrically connected to the battery cell 3, that is, the wiring harness connected to the conductive bar 4 is limited and fixed in the groove 11 of the bracket 1; the cover plate 2 includes a first electromagnetic shielding layer 23 and a first insulating layer 22 with the same structure, and the first insulating layer 22 is respectively bonded on opposite sides of the first electromagnetic shielding layer 23, that is, the two first insulating layers 22 cover the first electromagnetic shielding layer 23 inside; when the cover plate 2 is covered on the groove 11, the first insulating layer 22 located at the lower layer is used to abut against the wiring harness located in the groove 11. The length direction of the bracket 1 is specifically as follows Figure 2 As shown by arrow A in FIG.

[0043] By setting the bracket 1 on the battery cell 3, the wiring harness electrically connected to the battery cell 3 is placed in the groove 11 on the bracket 1, so that the battery cell 3 and the wiring harness can be separated by the bracket 1, and direct contact between the wiring harness and the battery cell 3 can be avoided, so that the heat generated by the battery cell 3 can be prevented from affecting the wiring harness, thereby better protecting the wiring harness and improving the electrical safety protection level of the battery module; at the same time, the cover plate 2 is covered to the groove 11, and the first insulating layer 22 located at the lower layer of the cover plate 2 is abutted against the wiring harness, so that the insulation of the wiring harness can be limited and fixed between the groove 11 and the cover plate 2, so as to better limit the movement of the wiring harness and avoid the random movement of the wiring harness, which is conducive to the unified routing of the wiring harness and can provide better protection for the wiring harness; and the use of protective belts such as buckles or cable ties is reduced, saving costs.

[0044] Compared with the prior art, the wiring harness structure in this embodiment is provided with a first electromagnetic shielding layer 23 in the cover plate 2; the first electromagnetic shielding layer 23 can provide electromagnetic shielding for the wiring harness in the groove 11, so as to ensure that the collected signal of the wiring harness is more accurate. Compared with wrapping the electromagnetic shielding layer around the periphery of each wiring harness, the wiring harness can be thinner and occupy less space in the groove 11, so as to ensure that the groove 11 can provide more wiring harness accommodating space, which is conducive to saving space in the groove 11, and saves time and effort, thereby saving time and cost.

[0045] That is, the cover plate 2 in this embodiment not only has the function of limiting and pressing the wire harness, but also can protect the wire harness, and also has an electromagnetic shielding effect, so that the wire harness has an electromagnetic anti-interference function, and can hide the wire harness in the groove 11, so that the appearance of the groove 11 after the wire harness is placed is more beautiful. The thickness of the cover plate 2 in this embodiment is about 1mm, which will not increase the occupied area of ​​the entire wire harness structure.

[0046] Furthermore, if Figure 2 and Figure 3 As shown, the distance between the inner bottom end face 111 of the groove 11 and the lower bottom end face of the cover plate 2 is H1, and the height of the wiring harness in the groove 11 is H2, H1≤H2≤1.1 times of H1, so as to ensure that the distance H1 between the inner bottom end face 111 of the groove 11 and the lower bottom end face of the cover plate 2 matches the height H2 of the wiring harness in the groove 11; on the one hand, when the cover plate 2 is covered on the groove 11, it can ensure that the cover plate 2 is pressed against the wiring harness, so that the cover plate 2 can have a pressing and limiting effect on the wiring harness; on the other hand, it can avoid that the height of the wiring harness is too high, resulting in the cover plate 2 being unable to cover the groove 11, and ensure the smooth covering connection between the cover plate 2 and the groove 11. Among them, the lower bottom end face of the cover plate 2 specifically refers to the bottom end face of the first insulating layer 22 located in the lower layer of the cover plate 2, and the lower bottom end face of the cover plate 2 is close to the bottom end face of the bracket 1, that is, the lower bottom end face of the cover plate 2 is arranged opposite to the inner bottom end face 111 of the groove 11.

[0047] It is worth noting that the groove width of the groove 11 matches the width of the wire harness, so that the groove 11 can accommodate wire harnesses of various widths, making the entire wire harness structure more versatile and applicable.

[0048] Specifically, a second electromagnetic shielding layer (not shown in the figure) is provided inside the bracket 1, and the second electromagnetic shielding layer is arranged corresponding to the groove 11, that is, the second electromagnetic shielding layer is located at the groove 11; and a second insulating layer (not shown in the figure) is laid in the groove 11 to make each surface of the groove 11 have an insulating effect; the second insulating layer is located above the second electromagnetic shielding layer, so that the second electromagnetic shielding layer can be covered inside the bracket 1 through the second insulating layer, so that the entire groove 11 can provide electromagnetic shielding and insulation effects for the wiring harness therein at the same time.

[0049] Specifically, there is no limitation on the structure of the second electromagnetic shielding layer, as long as the second electromagnetic shielding layer can cover the entire groove 11; there is no limitation on the structure of the second insulating layer, as long as the second insulating layer can cover the entire surface of the groove 11; that is, when the wiring harness is placed in the groove 11, the second insulating layer directly contacts the wiring harness to achieve insulation, and the second electromagnetic shielding layer will not contact the wiring harness, and the second electromagnetic shielding layer will only provide electromagnetic shielding effect for the wiring harness in the groove 11.

[0050] By providing a second electromagnetic shielding layer corresponding to the groove 11, it is possible to further provide an electromagnetic shielding effect on the basis of the first electromagnetic shielding layer 23, that is, the two layers of battery shielding layers can make the electromagnetic interference resistance of the wire harness in the groove 11 better, thereby ensuring that the collected signal of the wire harness is more accurate; and a Faraday cage can be formed between the second electromagnetic shielding layer at the groove 11 and the first electromagnetic shielding layer 23 on the cover plate 2, and the wire harness is limited in the Faraday cage, which can further make the electromagnetic interference resistance of the wire harness better, thereby further ensuring the stability and accuracy of the collected signal of the wire harness. Among them, the Faraday cage specifically refers to a cage formed by metal or a good conductor.

[0051] Specifically, the materials of the first electromagnetic shielding layer 23 and the second electromagnetic shielding layer may be the same or different, as long as the materials of the first electromagnetic shielding layer 23 and the second electromagnetic shielding layer are conductive metal materials, which is not specifically limited here.

[0052] The materials of the first insulating layer 22 and the second insulating layer can be the same or different, as long as the materials of the first insulating layer 22 and the second insulating layer are insulating materials. In this embodiment, the material of the first insulating layer 22 is polycarbonate (abbreviated as PC) with good structural strength, and the material of the second insulating layer is the same as the material of the bracket 1, both of which are plastic materials.

[0053] Furthermore, if Figure 3 As shown, the bracket 1 and the second insulating layer are an integrated structure, which is simple and convenient to process, and the second electromagnetic shielding layer is coated inside the integrated structure; that is, during processing, the second electromagnetic shielding layer is placed in a plastic material, so that an integrated structure coated with the second electromagnetic shielding layer can be formed. In this embodiment, the bracket 1, the second electromagnetic shielding layer and the second insulating layer are formed by vacuum molding. Vacuum molding specifically refers to a plastic processing technology. The main principle is to heat and soften a flat plastic hard sheet, vacuum adsorb it on the mold surface, and cool it to form it.

[0054] Specifically, Figures 1 to 3As shown, a hollow protrusion 14 and a side plate 13 are respectively provided on the bracket 1. The hollow protrusion 14 is used to be arranged opposite to the explosion-proof valve 31 of the battery cell 3. In the width direction of the bracket 1, the space between the side plates 13 on the opposite sides of the hollow protrusion 14 is the above-mentioned groove 11. The first gap 112 between the side plate 13 on one side and one side of the hollow protrusion 14 is used to accommodate the wiring harness of the connection row 42. The second gap 113 between the side plate 13 on the other side and the other side of the hollow protrusion 14 is used to accommodate the wiring harness of the output row 41. The wiring harness of the connection row 42 or the wiring harness of the output row 41 can be routed in the third gap 114 between two adjacent hollow protrusions 14, respectively, so as to realize the limited routing of the wiring harness in the entire groove 11. Among them, the width direction of the bracket 1 is specifically as shown in FIG. Figure 2 and Figure 3 As shown by arrow B in FIG.

[0055] It is worth noting that if Figure 1 As shown, since the bracket 1 is directly placed on each battery cell 3, it is necessary to ensure that the hollow protrusion 14 on the bracket 1 is arranged correspondingly to the pressure relief port of the explosion-proof valve 31 of the battery cell 3, that is, the pressure relief port and the hollow hole 141 in the hollow protrusion 14 are arranged directly opposite to each other, so that the pressure or heat leaked from the pressure relief port can be discharged outside through the hollow hole 141 of the hollow protrusion 14; and, the wiring harness in the groove 11 needs to avoid the top of the hollow protrusion 14 to ensure that the pressure relief port of the explosion-proof valve 31 will not affect the wiring harness.

[0056] Specifically, if Figures 1 to 3 As shown, outlets 16 connected to the groove 11 are provided at the opposite ends of the length direction of the bracket 1, so that the wire harness in the groove 11 can pass through; and, a plurality of inlets 15 are provided at intervals on the side panels 13 on each side, and the wire harness of the connection row 42 or the wire harness of the output row 41 can pass through the corresponding inlet 15 to enter the groove 11, so that the wire harness is limited in the groove 11 and then passes through the outlets 16 at both ends of the bracket 1 to the outside of the entire wire harness structure, so that the wire harness can be connected to the external controller. Among them, the controller is used to collect and process the working parameters of the battery cell 3 collected in the wire harness. The controller adopts a common control structure in the prior art, and the control principle of the controller is not described in detail here. Further, the cover plate 2 can be detachably connected to the bracket 1, so as to facilitate the quick disassembly and assembly between the cover plate 2 and the bracket 1, thereby facilitating the quick placement of the wire harness in the groove 11, saving time and effort, and improving work efficiency; and when the cover plate 2 is damaged, the cover plate 2 can be quickly replaced.

[0057] Specifically, if Figures 5 to 7As shown, a clamping hole 12 is provided on one of the cover plate 2 and the side plate 13, and a clamping protrusion 21 is provided on the other, and the clamping protrusion 21 can be clamped into the clamping hole 12, so as to realize the detachable connection between the cover plate 2 and the bracket 1. In other embodiments, the detachable connection between the cover plate 2 and the bracket 1 can also be realized by bolt fastening, and the specific detachable connection method is not limited here.

[0058] In this embodiment, Figure 5 and Figure 7 As shown, a clamping hole 12 is provided on the side plate 13, and a clamping protrusion 21 is provided on the cover plate 2; the cover plate 2 is connected to the groove 11 by using the side plate 13 forming the groove 11, thereby saving space; and, after the cover plate 2 is buckled with the bracket 1, an integrated seamless connection effect can be formed between the cover plate 2 and the bracket 1, which can make the overall assembly between the cover plate 2 and the bracket 1 simpler and more beautiful. Among them, a plurality of clamping holes 12 are provided on the side plate 13, and a plurality of clamping protrusions 21 are provided on the cover plate 2, and one clamping protrusion 21 is clamped into one clamping hole 12, thereby ensuring that the connection between the cover plate 2 and the bracket 1 is relatively stable.

[0059] Furthermore, if Figure 8 As shown, the gap H3 between the edge of the cover plate 2 and the side plate 13 is less than or equal to 5 mm, that is, when the cover plate 2 is covered on the groove 11, the edge of the cover plate 2 and the side plate 13 are not completely abutted, so that the cover plate 2 can be removed from the groove 11 through the gap between the edge of the cover plate 2 and the side plate 13, which is beneficial to the loading and unloading of the cover plate 2; moreover, it can be ensured that the gap between the edge of the cover plate 2 and the side plate 13 is not too large, so as to ensure the stability of the connection between the cover plate 2 and the bracket 1, and there will be no problem of the cover plate 2 shaking on the bracket 1 or even detaching.

[0060] Furthermore, if Figures 2 to 6 As shown, a shielding protrusion 25 is also provided on the cover plate 2. On the same side of the cover plate 2, the shielding protrusion 25 and the clamping protrusion 21 are arranged at intervals; when the clamping protrusion 21 is clamped into the clamping hole 12, a shielding protrusion 25 can be plugged into a wire inlet 15; on the one hand, the plugging effect between the shielding protrusion 25 and the wire inlet 15 can provide a limiting effect for the cover plate 2, so that the cover plate 2 can be more stably installed on the bracket 1, ensuring that the connection between the cover plate 2 and the bracket 1 is more stable; on the other hand, the shielding protrusion 25 can shield the wire harness at the wire inlet 15 to ensure the protection of the wire harness; at the same time, the overall aesthetics of the cover plate 2 after being installed on the bracket 1 can be better. Among them, a plurality of shielding protrusions 25 are provided on the same side of the cover plate 2, and the specific number of shielding protrusions 25 is not limited here, and the structure of the shielding protrusion 25 matches the structure of the wire inlet 15.

[0061] The wiring harness structural member in this embodiment, by providing a cover plate 2 integrated with a first electromagnetic shielding layer 23, and integrating a second electromagnetic shielding layer in the groove 11, can ensure the electromagnetic shielding effect of the wiring harness in the groove 11, so that the electromagnetic interference resistance of the wiring harness in the groove 11 is better; and, limiting the wiring harness between the groove 11 and the cover plate 2 can be beneficial to the unified routing management of the wiring harness, and can restrain the movement of the wiring harness; and can prevent the heat generated by the battery cell 3 from affecting the wiring harness, and has a better protective effect on the wiring harness; at the same time, by clamping the protrusion 21 into the clamping hole 12, and plugging the shielding protrusion 25 into the wire inlet 15, the cover plate 2 can be relatively stably installed on the bracket 1, and the installation method is detachable, simple and convenient.
