[0031] The embodiments of the present application provide a bracket assembly, a wiring harness integrated assembly, and a battery module, which are described in detail below. It should be noted that the order of description of the following embodiments does not limit the preferred order of the embodiments.

[0032] First, an embodiment of the present application provides a bracket assembly, which is used for a battery module. The battery module is composed of multiple battery cells connected in series or in parallel. When connecting multiple battery cells in series or in parallel, and collecting and outputting signals such as the voltage or temperature of the battery module, it is necessary to set a bracket assembly above the battery cell to facilitate the installation of the connection assembly, collection harness and connector for connecting the battery cells.

[0033] As shown in Figures 1 and 2, the bracket assembly 100 includes a harness bracket 110 and a fixing bracket 120, which is detachably connected to the harness bracket 110. The harness bracket 110 is used to mount the collection harness 200. A mounting portion 111 is provided on one side of the harness bracket 110 for mounting the connector 400. A first connecting portion 112 is protruded from the mounting portion 111 to facilitate the detachable installation of the fixing bracket 120.

[0034] The fixing bracket 120 includes a fixing portion 121 and a second connecting portion 122 connected to each other. The fixing portion 121 is used to mount the connector 400, and the second connecting portion 122 is detachably connected to the first connecting portion 112. That is, the fixing bracket 120 and the connector 400 are integrally mounted on the mounting portion 111 of the wiring harness bracket 110, and the second connecting portion 122 cooperates with the first connecting portion 112 to achieve a detachable connection between the fixing bracket 120 and the wiring harness bracket 110.

[0035] That is, when installing the connector 400, first install the connector 400 on the fixing portion 121 of the fixing bracket 120, then electrically connect the collection harness 200 to the connector 400, and then install the fixing bracket 120, the connector 400, and the collection harness 200 as a whole on the harness bracket 110 through the connection between the second connecting portion 122 and the first connecting portion 112, and fix the collection harness 200 on the harness bracket 110. This can prevent the collection harness 200 from becoming too long and loose after the connector 400 is fixed, and avoid collision between the collection harness 200 and other structures during vibration testing, thereby reducing the risk of signal acquisition failure. At the same time, the detachable connection between the fixing bracket 120 and the harness bracket 110 can also prevent the inability to effectively fix the connector 400 due to the small stacking space of the battery module 1.

[0036] It should be noted that there is no special restriction on the specific structure and connection method of the first connecting part 112 and the second connecting part 122. It is only necessary to ensure that the fixing bracket 120 and the wiring harness bracket 110 are two independent entities and can adopt a detachable connection method.

[0037] In the embodiment of the present application, the bracket assembly 100 is used for the battery module 1. The bracket assembly 100 includes a wiring harness bracket 110 and a fixing bracket 120. The wiring harness bracket 110 is used to install the collection wiring harness 200. A mounting portion 111 is provided on one side of the wiring harness bracket 110. The mounting portion 111 is used to install the connector 400. A first connecting portion 112 is protruded from the mounting portion 111. The fixing bracket 120 is detachably connected to the wiring harness bracket 110. The fixing bracket 120 includes a fixing portion 121 and a second connecting portion 122 that are connected to each other. The fixing portion 121 is used to install the connector 400. The second connecting portion 122 is detachably connected to the first connecting portion 112. The present application provides a fixing bracket 120 that is detachably connected to the harness bracket 110, so that when the connector 400 and the collection harness 200 are installed on the harness bracket 110, the connector 400 can be fixed first using the fixing portion 121 of the fixing bracket 120, and then the collection harness 200 is electrically connected to the connector 400. Thereafter, the fixing bracket 120, the connector 400 and the collection harness 200 are installed as a whole on the harness bracket 110 through the connection between the second connecting portion 122 and the first connecting portion 112, thereby preventing the collection harness 200 from becoming loose due to being too long after the connector 400 is fixed, thereby reducing the risk of signal acquisition failure.

[0038] Optionally, as shown in Figures 3, 4, and 5, a slider 123 is connected to the side of the second connecting portion 122 facing the first connecting portion 112, and a slide groove 1121 is formed on the side of the first connecting portion 112 facing the second connecting portion 122. The slide groove 1121 extends in a direction away from the mounting portion 111, and the slide groove 1121 forms a mounting opening 1122 on the side of the first connecting portion 112 away from the mounting portion 111. The slider 123 slides through the mounting opening 1122 and is embedded in the slide groove 1121. That is, when the fixing bracket 120 is mounted on the mounting portion 111 of the wiring harness bracket 110, the slider 123 on the second connecting portion 122 slides from the mounting opening 1122 of the first connecting portion 112 into the slide groove 1121 and slides along the extending direction of the slide groove 1121 until they abut against each other.

[0039] During installation, the plasticity of the first connection part 112 can be directly utilized to deform the first connection part 112. After the slider 123 slides into the slide groove 1121, the reaction force of the plastic deformation is utilized to achieve mutual abutment between the first connection part 112 and the second connection part 122.

[0040] In some embodiments, a stop block 1123 is protruding from the bottom of the chute 1121, and a relief groove 1231 is defined on the side of the slider 123 facing the stop block 1123. The relief groove 1231 extends through the slider 123 along its sliding direction, and the relief groove 1231 is used to avoid the stop block 1123. An abutment block 124 is protruding from the bottom of the abutment groove 1231, and the abutment block 124 is used to abut against the side of the stop block 1123 facing away from the installation opening 1122. In other words, when the slider 123 is slid from the installation opening 1122 into the chute 1121, the abutment block 124 on the slider 123 slides to the side of the stop block 1123 in the chute 1121 facing away from the installation opening 1122 and abuts against it. The stop block 1123 is then located in the relief groove 1231, thereby achieving the clamping connection between the fixing bracket 120 and the wiring harness bracket 110. At this time, the limiting block 1123 can limit the upward movement of the fixing bracket 120 to prevent the fixing bracket 120 from moving upward and separating from the wiring harness bracket 110 .

[0041] Among them, the surface that first contacts the limit block 1123 during the sliding process of the slider 123 can be set as an inclined surface to reduce the resistance of the slider 123 during the sliding process of the slider 123 sliding into the slide groove 1121, thereby facilitating the installation of the fixed bracket 120 and the wiring harness bracket 110.

[0042] In other embodiments, a gap is provided between the slider 123 and the second connection portion 122. Positioning portions 1124 are provided on two opposing sidewalls of the slide groove 1121. The positioning portions 1124 are configured to abut against the side of the slider 123 facing the second connection portion 122. Specifically, the end of the slider 123 facing away from the mounting portion 111 is connected to the second connection portion 122, while the end of the slider 123 facing the mounting portion 111 is spaced from the second connection portion 122, with a gap formed between the two ends.

[0043] That is to say, when the fixing bracket 120 and the wiring harness bracket 110 are installed, the slider 123 slides from the installation opening 1122 into the gap between the limiting portion 1124 and the bottom of the slide groove 1121, and the slider 123 abuts against the limiting portion 1124 on the side facing the second connection portion 122, that is, the limiting portion 1124 is located between the second connection portion 122 and the slider 123, so as to limit the movement of the fixing bracket 120 in the front, back, left and right directions, so as to further improve the installation stability of the fixing bracket 120 and the wiring harness bracket 110.

[0044] It should be noted that the setting positions of the slide groove 1121 on the first connecting part 112 and the slider 123 on the second connecting part 122 can be interchanged, that is, a slider is set on the first connecting part 112, and a slide groove is set on the second connecting part 122, so that the fixing bracket 120 and the wiring harness bracket 110 can be detachably connected. The specific structure can be referred to the relevant description in the above embodiment, and will not be repeated here.

[0045] Optionally, two first connecting portions 112 are protruding from the mounting portion 111, and the two first connecting portions 112 are arranged in parallel along the first direction X. The fixing bracket 120 includes two second connecting portions 122, and the two second connecting portions 122 are connected to opposite ends of the fixing portion 121 along the first direction X. The second connecting portions 122 are connected to the first connecting portions 112 in a one-to-one correspondence. That is, the opposite ends of the fixing bracket 120 in the first direction X are simultaneously connected to the wiring harness bracket 110, which can not only improve the installation stability of the fixing bracket 120, but also make the force on the fixing bracket 120 more uniform, which helps to improve the structural stability of the fixing bracket 120.

[0046] In some embodiments, the fixing portion 121 has a first side surface 1211 and a second side surface 1212 that are opposite to each other along the second direction Y. The second connecting portion 122 is connected to the second side surface 1212. The first side surface 1211 is provided with a mounting groove 1213 that extends along the second direction Y and penetrates the second side surface 1212. The sidewalls of the mounting groove 1213 are configured to abut against the connector 400. That is, when installing the connector 400, the connector 400 can be installed from the first side surface 1211 to the mounting groove 1213 and extended from the second side surface 1212. The sidewalls of the mounting groove 1213 abut against the connector 400, thereby securing the connector 400. The end of the connector 400 that extends from the second side surface 1212 is configured to be electrically connected to the collection harness 200.

[0047] The second direction Y corresponds to the arrangement direction of the multiple battery cells 20 in the battery module 1, and the first direction X is a direction perpendicular to the second direction Y on the horizontal plane, that is, the first direction X is the distribution direction of the positive and negative poles in a single battery cell 20.

[0048] In other embodiments, the first side 1211 is provided with at least two mounting grooves 1213, which are arranged at intervals along the first direction X. Each mounting groove 1213 can be used to install a connector 400, so that at least two connectors 400 of the same type or different types can be installed on the fixing bracket 120 at the same time to meet different design requirements of the battery module 1.

[0049] Secondly, an embodiment of the present application also provides a wiring harness integrated assembly, which includes a bracket assembly. The specific structure of the bracket assembly refers to the above embodiment. Since this wiring harness integrated assembly adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0050] As shown in Figures 1 and 2, the wiring harness integrated assembly 10 includes a bracket assembly 100, a connecting assembly 300, a collection harness 200, and a connector 400. The connecting assembly 300 is arranged on the harness bracket 110 of the bracket assembly 100. The connecting assembly 300 is used to electrically connect to the electrodes of the battery cells 20 in the battery module 1. The collection harness 200 is arranged on the harness bracket 110 of the bracket assembly 100, and the collection harness 200 is electrically connected to the connecting assembly 300 to collect signals such as the voltage and temperature of the battery cells 20. The connector 400 is installed on the fixing portion 121 of the fixing bracket 120 in the bracket assembly 100, and the connector 400 is electrically connected to the collection harness 200 to output the signals collected by the collection harness 200. In this application, by integrating the collection harness 200, the connecting assembly 300, and the connector 400 into a single bracket assembly 100, the wiring harness integrated assembly 10 in the battery module 1 can be highly integrated, so as to facilitate the rapid assembly of the battery module 1.

[0051] Specifically, the bracket assembly 100 includes a wiring harness bracket 110 and a fixing bracket 120. A mounting portion 111 is provided on one side of the wiring harness bracket 110. A first connecting portion 112 is protruded from the mounting portion 111. The fixing bracket 120 includes a fixing portion 121 and a second connecting portion 122 that are connected to each other. The fixing portion 121 is used to install the connector 400, and the second connecting portion 122 is detachably connected to the first connecting portion 112. The present application provides a fixing bracket 120 that is detachably connected to the harness bracket 110, so that when the connector 400 and the collection harness 200 are installed on the harness bracket 110, the connector 400 can be fixed first using the fixing portion 121 of the fixing bracket 120, and then the collection harness 200 is electrically connected to the connector 400. Thereafter, the fixing bracket 120, the connector 400 and the collection harness 200 are installed as a whole on the harness bracket 110 through the connection between the second connecting portion 122 and the first connecting portion 112, thereby preventing the collection harness 200 from becoming loose due to being too long after the connector 400 is fixed, thereby reducing the risk of signal acquisition failure.

[0052] The fixing portion 121 is provided with a mounting groove 1213, and an elastic member 410 is provided on at least one side of the connector 400. The elastic member 410 abuts against the sidewalls of the mounting groove 1213 on the fixing portion 121, thereby enabling the connector 400 to be installed within the mounting groove 1213. By providing the elastic member 410 on at least one side of the connector 400, when the connector 400 is installed in the mounting groove 1213, the elastic deformation of the elastic member 410 can be utilized to achieve effective abutment between the connector 400 and the sidewalls of the mounting groove 1213, thereby ensuring the installation stability of the connector 400. Furthermore, due to the elasticity of the elastic member 410, the fixing bracket 120 and the connector 400 can be matched to a tolerance. That is, the mounting groove 1213 on the fixing bracket 120 can simultaneously accommodate connectors 400 of different sizes, thereby improving the applicability of the fixing bracket 120.

[0053] In some embodiments, an elastic member 410 is provided on opposite sides of the connector 400 in the first direction X, so that the connector 400 and the mounting groove 1213 of the fixing bracket 120 can be fixed symmetrically to reduce stress concentration generated during the fixing process.

[0054] The connection assembly 300 includes a first connector and a second connector. The first connector is used to connect two adjacent battery cells 20 in the battery module 1 to achieve series or parallel connection of the two adjacent battery cells 20. The second connector is used to electrically connect to the output electrodes of the battery module 1. The output electrodes of the battery module 1 are located at both ends of the arrangement direction of the multiple battery cells 20 in the battery module 1. That is, the second connector is provided at both ends of the wiring harness bracket 110 to facilitate the connection design between the battery module 1 and the external output circuit.

[0055] It should be noted that one end of the collection harness 200 connected to the connection assembly 300 is equipped with a thermistor (NTC) to monitor the temperature of the corresponding battery cell 20 in the battery module 1. After welding the collection harness 200 to the first or second connector in the connection assembly 300, a layer of UV adhesive can be applied to the joint to enhance the weld strength between the collection harness 200 and the connection assembly 300. This also prevents foreign matter from contacting the weld area between the collection harness 200 and the connection assembly 300, thereby improving the connection stability between the collection harness 200 and the connection assembly 300.

[0056] Finally, an embodiment of the present application also provides a battery module, which includes a wiring harness integrated assembly. The specific structure of the wiring harness integrated assembly refers to the above embodiment. Since this battery module adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0057] As shown in Figure 6, the battery module 1 includes multiple battery cells 20 and a wiring harness integrated assembly 10. The wiring harness integrated assembly 10 is electrically connected to the battery cells 20 to collect signals such as the voltage and temperature of the battery cells 20, and is electrically connected to the BMS module through a connector 400 to output signals such as the voltage and temperature monitored by the collection harness 200, thereby realizing the monitoring and maintenance of the working status and performance of the battery module 1 to ensure the safe and stable use of the battery module 1.

[0058] Specifically, as shown in Figures 1 and 2, the wiring harness integrated assembly 10 includes a bracket assembly 100, the bracket assembly 100 includes a wiring harness bracket 110 and a fixing bracket 120, a mounting portion 111 is provided on one side of the wiring harness bracket 110, a first connecting portion 112 is protruded on the mounting portion 111, the fixing bracket 120 includes a fixing portion 121 and a second connecting portion 122 connected to each other, the fixing portion 121 is used to install the connector 400, and the second connecting portion 122 is detachably connected to the first connecting portion 112. The present application provides a fixing bracket 120 that is detachably connected to the harness bracket 110, so that when the connector 400 and the collection harness 200 are installed on the harness bracket 110, the connector 400 can be fixed first using the fixing portion 121 of the fixing bracket 120, and then the collection harness 200 is electrically connected to the connector 400. Thereafter, the fixing bracket 120, the connector 400 and the collection harness 200 are installed as a whole on the harness bracket 110 through the connection between the second connecting portion 122 and the first connecting portion 112, and the collection harness 200 is fixed on the harness bracket 110, thereby preventing the collection harness 200 from being too long and loosening after the connector 400 is fixed, thereby reducing the risk of signal acquisition failure.
