Therefore, the wiring harness is an important basic concept in traffic theory; the load source is the service object of the wiring harness, usually referring to the user equipment; in a broad sense, the upper-level equipment is the load source of the lower-level equipment. The wiring harness has a wide range of applications in various fields, and the processing of the wiring harness has become particularly important.

[0003] In the related technology, the wiring harness is generally fixed by bundling it with a cable tie, which causes the wiring harnesses to be compressed against each other, which can easily damage the insulation layer, causing a series of problems such as electrical function failure. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a wiring harness device and a battery pack, which can prevent the wiring harnesses from being compressed and rubbed against each other, causing damage to the insulation layer and avoiding electrical function failure.

According to the elasticity of the first elastic arm and the second elastic arm, the tolerance accumulation can be ignored. Within the allowable error range, wiring harness assemblies of different diameters can be adapted without the result of misassembly.

Within the allowable error range, wiring harness assemblies of different diameters can be adapted, and the result of the wiring harness assembly not being able to be assembled will not occur. At the same time, the entire fixing process is convenient and the assembly process is simple, which avoids the time waste caused by manual use of multiple cable ties to bundle, and greatly improves production efficiency.

[0014] In some embodiments, the first elastic arm and the second elastic arm are spaced apart to form an installation opening, and the opening direction of the installation opening is the direction in which the fixing member is away from the bottom plate.

[0015] In some embodiments, a convex portion is disposed on one side of the bottom plate close to the fixing member, so as to prevent the binding from failing after movement due to vibration when the bottom plate is bound.

[0034] Example

[0035] With the development of technology and the introduction of the "carbon neutrality and carbon peak" policy, traditional fuel vehicles are gradually being replaced by new energy vehicles. Among them, electric vehicles are a type of new energy vehicles. The fixation of wiring harnesses in the battery pack has always been an unavoidable topic in the design of battery packs. At the same time, safety is also the topic that consumers are most concerned about.

[0036] During the design process, the inventor found that in the process of battery pack design, two different high and low voltage harnesses often run in parallel for a long distance. One of the existing processing methods is to tie the high and low voltage harnesses with cable ties and then fix them with fir heads or sheet metal buckles. This method has the following disadvantages: 1. It will cause the harnesses to press against each other, which can easily damage the insulation layer and cause electrical function failure; 2. The cable ties need to be manually tied and positioned, and the excess parts at the ends need to be trimmed after the tying is completed, which is complicated to operate and inefficient; 3. Multiple cable ties are required for tying, which is not only extremely inconvenient to install, but also extremely inconvenient to repair and disassemble, and it is easy to cause environmental pollution; 4. The distance between the high and low voltage harnesses is too close, and the high voltage harness is easy to generate electromagnetic interference to the low voltage harness, resulting in signal loss and safety hazards. At the same time, for the interior of the battery pack, sensors are generally required, which not only has low integration, but also requires additional fixed brackets to fix the sensors, which has low space utilization and high cost.

[0037] In view of this, if Figure 1-Figure 3As shown, in the first aspect, an embodiment of the present application provides a wiring harness device, including: a fixing assembly 100, including a base plate 101 and a fixing member 102, the base plate 101 is penetrated by a fixing hole 103, the fixing hole 103 is configured to be used for fixing the fixing assembly 100, and the side of the base plate 101 away from the fixing member 102 is configured to be bonded to an external device (i.e., an opponent member), the fixing member 102 is connected to the base plate 101, and the fixing member 102 is configured with a accommodating space along a first direction, and the accommodating space is configured to accommodate the wiring harness assembly.

[0038] Exemplarily, the fixing method of the base plate 101 to the fixing part 102 includes but is not limited to integral molding, and the side of the base plate 101 facing away from the fixing part 102 is configured to be smooth, that is, the surface of the base plate 101 is flat, without protrusions and spikes. When fixing it, not only can the fixing hole 103 be fixed by bolts, the bolts can be standard parts, and glue is applied to the entire smooth surface of the base plate 101 to stick it to the opponent.

[0039] The first direction is the direction in which the wiring harness assembly passes through the fixing part 102, and the first direction includes but is not limited to the left and right direction. The fixing hole 103 passes through the bottom plate 101 in the up and down direction. There are two fixing holes 103, and the two fixing holes 103 are distributed on the left and right sides of the fixing part 102. One of the fixing holes 103 is configured as a circle, and the other fixing hole 103 is configured as an oblong. Steel sleeves can be configured inside the two fixing holes 103, which can reduce the impact on the opening tolerance of the hand part during installation and prevent it from being misassembled.

[0040] In the above implementation process, the fixing member 102 is connected to the bottom plate 101, and double fixation is achieved by fixing the fixing hole 103 on the bottom plate 101 and bonding the bottom plate 101. When the fixing member 102 fixes the wiring harness assembly, its accommodating space can accommodate the wiring harness assembly, thereby fixing the wiring harness assembly, preventing the wiring harnesses from being compressed and rubbed against each other to cause damage to the insulation layer, and avoiding electrical function failure.

[0041] like Figure 1-Figure 2As shown, two fixing members 102 are provided, the two fixing members 102 are distributed along the second direction, the ends of the two fixing members 102 are arranged flush, the wiring harness assembly includes a first wiring harness 300 and a second wiring harness, the first wiring harness 300 and the second wiring harness are copper wires or aluminum wires, etc., the first wiring harness 300 includes but is not limited to a high-voltage wiring harness, and the second wiring harness includes but is not limited to a low-voltage wiring harness, wherein one of the fixing members 102 is configured to fix the first wiring harness 300, and the other fixing member 102 is configured to fix the second wiring harness, and the second direction is perpendicular to the first direction.

[0042] In the above implementation process, two fixing members 102 are configured, one of which is used to accommodate the first wiring harness 300, and the other fixing member 102 is used to accommodate the second wiring harness. The first wiring harness 300 can be separated and fixed from the second wiring harness to avoid electromagnetic interference caused by the first wiring harness 300 and the second wiring harness being too close, resulting in signal loss and safety hazards. At the same time, the fixing process of the first wiring harness 300 and the second wiring harness is convenient, and the assembly process is simple, which avoids the time waste caused by manually using multiple cable ties to bundle, and greatly improves production efficiency.

[0043] like Figure 3 As shown, the fixing member 102 includes a first fixing arm 1021, a second fixing arm 1022, a first elastic arm 1023 and a second elastic arm 1024, the first fixing arm 1021 and the second fixing arm 1022 are spaced apart and both are connected to the base plate 101, the first elastic arm 1023 is connected to the first fixing arm 1021, and the second elastic arm 1024 is connected to the second fixing arm 1022.

[0044] In the above-mentioned implementation process, the first elastic arm 1023 is connected to the first fixed arm 1021, and the second elastic arm 1024 is connected to the second fixed arm 1022 to form an accommodating space. According to the elasticity of the first elastic arm 1023 and the second elastic arm 1024, it is possible to ignore the tolerance accumulation. Within the allowable error range, it can adapt to wiring harness assemblies of different diameters without the result of misassembly. At the same time, after the fixing part 102 is connected to the base plate 101, the entire structure can be installed and disassembled multiple times and reused, thereby reducing the pollution to the environment caused by waste generated by the use of cable ties.

[0045] In some embodiments, a first bending section is disposed on a side of the first elastic arm 1023 away from the bottom plate 101 , and a bending direction of the first bending section is a direction close to the second elastic arm 1024 ; and / or

[0046] A second bending section is disposed on a side of the second elastic arm 1024 facing away from the bottom plate 101 , and a bending direction of the second bending section is a direction close to the first elastic arm 1023 .

[0047] Exemplarily, the first elastic arm 1023 and the second elastic arm 1024 are bent along one side close to each other, and when the first elastic arm 1023 and the second elastic arm 1024 are squeezed by the wiring harness assembly, the first elastic arm 1023 and the second elastic arm 1024 are elastically deformed so that the wiring harness assembly moves along the inner walls of the first elastic arm 1023 and the second elastic arm 1024 to the accommodating space, and when the first elastic arm 1023 and the second elastic arm 1024 are not squeezed, the first elastic arm 1023 and the second elastic arm 1024 can both return to their original state.

[0048] In the above implementation process, by bending the first bending section and the second bending section, the wiring harness assembly can be conveniently fixed, and tolerance accumulation can be ignored. Within the allowable error range, wiring harness assemblies of different diameters can be adapted, and the result of the wiring harness assembly not being able to be assembled will not occur. At the same time, the entire fixing process is convenient and the assembly process is simple, which avoids the time waste caused by manual use of multiple cable ties to bundle, and greatly improves production efficiency.

[0049] In some embodiments, the first elastic arm 1023 and the second elastic arm 1024 are spaced apart to form an installation opening, the opening direction of the installation opening is the direction in which the fixing member 102 is away from the bottom plate 101, the wiring harness assembly can be assembled in the accommodation space from the installation opening, and when the wiring harness assembly is assembled, it can be fixed again by wrapping adhesive tape on the left and right sides of the bottom plate 101. The installation opening is formed between the first elastic arm 1023 and the second elastic arm 1024, which can facilitate the fixing process of the wiring harness assembly, simplify the assembly process, avoid the time waste caused by manually using multiple cable ties to bundle, and greatly improve production efficiency.

[0050] In some embodiments, a convex portion 104 is disposed on one side of the bottom plate 101 close to the fixing member 102, wherein the convex portion 104 may be distributed along the front-to-back direction, and two convex portions 104 are disposed, and the two convex portions 104 are located on the left and right sides of the fixing member 102, wherein the height of the convex portion 104 is not lower than the height of the bottom of the accommodation space, and the shape of the convex portion 104 may be configured as a triangular prism. This can prevent the bottom plate 101 from being strapped and failing after movement due to vibration.

[0051] like Figure 1-Figure 2As shown, the wiring harness device also includes a detection component 200, and the detection component 200 is connected to the bottom plate 101 for detecting the environment in which the wiring harness device is located. When the detection component 200 is integrated in the bottom plate 101 and the wiring harness device is used in a battery pack, the material of the bottom plate 101 includes but is not limited to non-metallic materials. It is possible to detect the information of the environment in which the wiring harness device is located in real time and provide feedback to achieve early warning of danger and protect personnel safety. At the same time, the detection component 200 is integrated in the bottom plate 101, which can improve space utilization and reduce the cost of additional brackets for fixing the detection component 200.

[0052] In some embodiments, the detection component 200 includes a temperature sensor assembly 201 (sensor body, signal transmission harness and control harness) and a humidity sensor assembly 202 (sensor body, signal transmission harness and control harness), and the temperature sensor assembly 201 and the humidity sensor assembly 202 are integrated into the base plate 101. By integrating the temperature sensor assembly 201 and the humidity sensor assembly 202 into the base plate 101, the temperature and humidity in the environment where the harness device is installed can be detected and real-time feedback can be provided to achieve early warning of danger and improve space utilization.

[0053] In some embodiments, the detection component 200 further includes a pressure sensor assembly 203 (sensor body, signal transmission harness and control harness) and a smoke sensor assembly 204 (sensor body, signal transmission harness and control harness), and the pressure sensor assembly 203 and the smoke sensor assembly 204 are integrated into the base plate 101. By integrating the pressure sensor assembly 203 and the smoke sensor assembly 204 into the base plate 101, the pressure and smoke in the environment where the harness device is installed can be detected (that is, the sensor body converts the detected information into an electrical signal, and the signal transmission harness is transferred to the battery management system), and the information is fed back to the battery management system (BMS) in real time. The battery management system can control the operation of the sensor by controlling the harness, realize early warning of danger, and improve space utilization.
