[0022] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0023] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The main solution of the embodiment of the present application is: the wiring harness assembly includes at least one wiring harness monomer; the wiring harness monomer includes a cable with adjustable length, and a connector is provided on the wiring harness monomer to be electrically connected to the cable, and the connector is used to connect adjacent wiring harness monomers to achieve electrical connection between the wiring harness monomers in the wiring harness assembly.

[0025] In the existing automotive wiring harness design, wire harnesses of fixed length corresponding to the distance between connected electrical devices are usually made according to the electrical layout under different vehicle models and configurations, and then all the wire harnesses are bundled into a wire harness assembly. Although this design simplifies the manufacturing process to a certain extent, due to the significant differences in electrical layout, equipment location and cable length requirements between different vehicle models and configurations, the wire harness assembly of one vehicle model or configuration is often difficult to adapt to other vehicle models or configurations, resulting in the need for automobile manufacturers to customize special wire harness assemblies for each vehicle model or configuration. In other words, the versatility of the wire harness assemblies of existing vehicles is poor.

[0026] The present application provides a solution, which uses a modular approach to construct a wiring harness assembly by connecting wiring harness monomers with adjustable length cables through connectors. Moreover, the wiring harness monomers are not completely independent, but can achieve signal and / or power transmission between the wiring harness monomers through connectors. Therefore, in the face of wiring harness requirements under different vehicle models and configurations, the present application can obtain a wiring harness assembly that is compatible with them by splicing single wiring harness monomers, greatly improving the versatility of wiring harness assemblies of existing vehicles.

[0027] Based on this, the embodiment of the present application provides a wiring harness assembly, referring to Figure 1 , Figure 1 This is a schematic structural diagram of an embodiment of a wiring harness assembly of the present application.

[0028] The wiring harness assembly includes at least one wiring harness monomer 100; The wiring harness monomer 100 includes a cable 110 with adjustable length. A connector 120 is provided on the wiring harness monomer 100 and electrically connected to the cable 110. The connector 120 is used to connect adjacent wiring harness monomers 100 to achieve electrical connection between the wiring harness monomers 100 in the wiring harness assembly.

[0029] Figure 1 In the example, a wiring harness assembly includes three wiring harness monomers 100. A cable 110 of a predetermined length can be stored in the wiring harness monomer 100, so that a cable 110 of a corresponding length can be pulled out from the wiring harness monomer 100 according to demand, so that the length of the cable 110 can be adjusted. Exemplarily, this embodiment can adopt a round or S-shaped storage cable 110. A connector 120 is provided on the wiring harness monomer 100, and the connector 120 is electrically connected to the cable 110. The connector 120 can realize the electrical connection between each wiring harness monomer 100 in the wiring harness assembly by connecting adjacent wiring harness monomers 100, so that signals and / or electrical energy can be transmitted between each wiring harness monomer 100. Exemplarily, the connector 120 may include a male connector and a female connector, and the male connector and the female connector may be respectively arranged on both sides of the wiring harness monomer 100. Figure 2 This is an assembly scenario diagram of the wiring harness assembly involved in the embodiment of the present application; after the connectors 120 of different wiring harness monomers 100 are docked, multiple wiring harness monomers 100 can be constructed into a wiring harness assembly adapted to the vehicle model and configuration according to different wiring harness layout requirements.

[0030] The embodiment of the present application is constructed into a wiring harness assembly by connecting the wiring harness monomers 100 with adjustable length cables 110 through connectors 120 in a modular manner. Moreover, the wiring harness monomers 100 are not completely independent, but the signal and / or power transmission between the wiring harness monomers can be realized through the connector 120. Therefore, in the face of wiring harness requirements under different vehicle models and configurations, the present embodiment can obtain a wiring harness assembly adapted thereto by splicing a single wiring harness monomer 100, which greatly improves the versatility of wiring harness assemblies of existing vehicles.

[0031] like Figure 3 As shown, Figure 3 The internal structure diagram of the wiring harness unit involved in the embodiment of the present application. In one embodiment, the wiring harness unit 100 includes a housing 130 and a winding device 140 disposed in the housing 130; The cable 110 of the harness unit 100 is wound around the winding device 140 , and the first connector port 111 and the second connector port 112 of the cable 110 are respectively extended out of the housing 130 through the first outlet 131 and the second outlet 132 of the housing 130 .

[0032] In this embodiment, the wiring harness monomer 100 includes a housing 130 and a winding device 140 disposed in the housing 130. Therefore, in this embodiment, the middle part of the cable 110 of the wiring harness monomer 100 is fixed on the winding device 140, and the cable 110 is wound on the winding device 140 by rotating the winding device 140. Then, in this embodiment, the first connector port 111 and the second connector port 112 can be stretched outward according to the requirement for the cable length, so that the wiring harness monomer 100 that meets the cable length requirement can be obtained.

[0033] In order to further improve the versatility of the wiring harness unit 100, see Figure 4 , Figure 4 1 is an internal structure diagram of a winding device according to an embodiment of the present application. In this embodiment, the cable 110 includes a first end cable 113 and a second end cable 114; One end of the first end cable 113 is a first connector port 111 , one end of the second end cable 114 is a second connector port 112 , and the other end of the first end cable 113 is connected to the other end of the second end cable 114 to form a complete cable 110 ; The winding device 140 includes two winding rotating bodies 141 , and the first end cable 113 and the second end cable 114 are respectively wound around the two winding rotating bodies 141 .

[0034] In actual use, due to certain requirements of electrical layout, after the connectors 120 of different harness units 100 are aligned and connected, different cable lengths are required at both ends of some harness units 100. If the winding device 140 has only one winding rotating body 141, then since the first end cable 113 and the second end cable 114 are both wound on the same winding rotating body 141, when the first end cable 113 is pulled out, the second end cable 114 will also be pulled out by the same length, and there will be extra length of cable 110 stretched to the housing 130. Therefore, if Figure 4 As shown, in this embodiment, the cable 110 includes a first end cable 113 (i.e. Figure 4 The black part of the cable) and the second end cable 114 (ie Figure 4 The red part of the cable in the figure); one end of the first end cable 113 is the first connector port 111, one end of the second end cable 114 is the second connector port 112, and the other end of the first end cable 113 is connected to the other end of the second end cable 114 to form a complete cable 110. Then, the first end cable 113 and the second end cable 114 are respectively wound on two winding rotating bodies 141, so that the cable lengths stretched out at both ends of the cable 110 can be relatively independent, and the cable lengths stretched out at both ends of the harness monomer 100 can be different, which can further broaden the applicable scenarios of the harness assembly.

[0035] See also Figure 5 and Figure 6 , Figure 5 for Figure 4 A schematic diagram of the structure of the cross section of the winding device A involved in the embodiment of the present invention. Figure 6 for Figure 4 Schematic diagram of the structure of the cross section of the winding device B involved in the embodiment. In this embodiment, the winding rotating body 141 includes a fixed shaft 1411, a winding disc 1412, a ratchet 1413, a pawl 1414 and a spiral spring 1415; The fixed shaft 1411 is fixedly installed in the housing 130 and passes through the winding reel 1412; The ratchet 1413 is disposed on the inner end surface of the winding disk 1412 and is coaxially disposed with the winding disk 1412. One end of the pawl 1414 is adjustable and meshed with the ratchet 1413. One end of the spiral spring 1415 is connected to the fixed shaft 1411, and the other end is connected to the winding disk 1412, so that the fixed shaft 1411 and the winding disk 1412 can rotate relative to each other by means of spring force or external force.

[0036] like Figure 5As shown, in this embodiment, a one-way locking assembly consisting of a ratchet 1413 and a pawl 1414 is provided on at least one side of the winding rotating body 141. The fixed shaft 1411 is fixedly installed in the housing 130, and the fixed shaft 1411 passes through the winding disk 1412, so as to fix the winding disk 1412 in the housing 130. The ratchet 1413 is provided on the inner end surface of the winding disk 1412 and is coaxially arranged with the winding disk 1412. One end of the pawl 1414 is adjustable in meshing with the ratchet 1413, that is, the position of the pawl 1414 can be adjusted so that one end of the pawl 1414 and the ratchet 1413 are in meshing state or non-meshing state. It can be understood that the direction of the ratchet teeth on the ratchet 1413 determines whether the one-way locking assembly of the pawl 1414 and the ratchet 1413 will be locked clockwise or counterclockwise in the meshing state. The winding disc 1412 and the ratchet wheel 1413 are relatively fixedly arranged, so that Figure 5 Taking the direction of the ratchet teeth on the middle ratchet 1413 as an example, when one end of the pawl 1414 is in a non-engaged state with the ratchet 1413, one end of the pawl 1414 is out of contact with the ratchet 1413, so no matter whether the winding disk 1412 rotates to drive the ratchet 1413 to rotate clockwise or counterclockwise, the pawl 1414 will not lock the ratchet 1413. When one end of the pawl 1414 is in an engaged state with the ratchet 1413, when the winding disk 1412 rotates to drive the ratchet 1413 to rotate clockwise, the pawl 1414 will not lock the ratchet 1413, but when the winding disk 1412 drives the ratchet 1413 to rotate counterclockwise, the pawl 1414 engages with the ratchet teeth on the ratchet 1413, locking the tendency of the winding disk 1412 to drive the ratchet 1413 to rotate counterclockwise.

[0037] As an example, when pulling out the cable 110, the winding drum 1412 in the winding rotating body 141 rotates clockwise, that is, the ratchet 1413 also rotates clockwise at this time. The present embodiment can also directly put the wiring harness assembly into use by first pulling out both ends of the cable 110 to a suitable length when one end of the pawl 1414 is in a meshing state with the ratchet 1413. In the case where it is necessary to adjust the length of the cable 110 of the wiring harness unit 100 in the wiring harness assembly, if it needs to be extended further, the two ends of the cable 110 can be directly pulled out of the housing 130. If it needs to be shortened, one end of the pawl 1414 and the ratchet 1413 can be adjusted to a non-meshing state, so that the cable 110 can be retracted into the housing 130. Figure 6As shown, in order to facilitate the retraction of the cable 110, the present embodiment further provides a spiral spring 1415 in the winding rotor 141. One end of the spiral spring 1415 is connected to the fixed shaft 1411, and the other end is connected to the winding drum 1412, so that the fixed shaft 1411 and the winding drum 1412 can be relatively rotated by means of spring force or external force. Of course, it can be understood that, as another example, when the cable 110 is pulled out, the winding drum 1412 in the winding rotor 141 rotates counterclockwise, that is, the ratchet 1413 also rotates counterclockwise at this time. In the present embodiment, one end of the pawl 1414 and the ratchet 1413 can be adjusted to a non-engaged state first, and then after the two ends of the cable 110 are pulled out to a suitable length, one end of the pawl 1414 and the ratchet 1413 are adjusted to an engaged state, so that the length of the two ends of the cable 110 can be locked to prevent the cable length from changing during subsequent use. Figure 6 Taking the arrangement of the spiral spring 1415 as an example, under the spring force of the spiral spring 1415, the winding drum 1412 rotates clockwise to store the cable 110 in the storage space between the housing 130 and the winding device 140. Under the external force of pulling the cable 110, the winding drum 1412 rotates counterclockwise to pull the cable 110 out of the housing 130 from the storage space between the housing 130 and the winding device 140.

[0038] In addition, if Figure 5 As shown, an unlocking mechanism 1416 is provided on the pawl 1414; The unlocking mechanism 1416 is used to control one end of the pawl 1414 to disengage from the tooth back surface of the ratchet 1413 to release the meshing state between the pawl 1414 and the ratchet 1413 .

[0039] In this embodiment, an unlocking mechanism 1416 is provided on the pawl 1414. Thus, the unlocking mechanism 1416 can be used to control one end of the pawl 1414 to be separated from the tooth back surface of the ratchet 1413, so as to release the meshing state between the pawl 1414 and the ratchet 1413. The unlocking mechanism 1416 can be an elastic element (such as a spring, a spring, etc.), and the elastic element can be deformed by an external force to make the pawl 1414 leave the tooth back surface of the ratchet 1413. When the external force disappears, the elastic element returns to its original shape, so that the pawl 1414 contacts the tooth back surface of the ratchet 1413 again and returns to the locked position, thereby realizing the one-way locking function. The unlocking mechanism 1416 can also be an electromagnetic element, which can attract or release the pawl 1414 by changing the power-on state of the electromagnetic element, so as to realize the unlocking and locking of the pawl 1414 to the ratchet 1413. The unlocking mechanism 1416 can also be a mechanical structure such as a pin, a lever, etc. that can change the position or state of the pawl 1414.

[0040] See also Figure 7 and Figure 8 , Figure 7 This is a structural schematic diagram of another embodiment of the wiring harness assembly of the present application. Figure 8 Schematic diagram of electrical connection of the wiring harness assembly involved in the embodiment of the present application. In this embodiment, the wiring harness assembly further includes: a controller 150; the controller 150 is electrically connected to the connector 120 of the wiring harness monomer 100; the controller 150 includes a loop control module 151, which is used to control the on and off of the connector 120 on the wiring harness monomer 100 according to the loop configuration information of the wiring harness assembly.

[0041] like Figure 7 As described, after the controller 150 and the connector 120 of the wiring harness monomer 100, the on-off control of the connector 120 on the wiring harness monomer 100 can be realized. Because in the actual use scenario, the electrical devices connected to the wiring harness assembly are not just one-to-one connection relationships, there may be multiple electrical devices connected to a main component, or multiple electrical devices are connected to each other. Due to different models or configurations, the connection relationship of different electrical devices will also be more obvious. Therefore, in this embodiment, the controller 150 can be configured for the wiring harness assembly, so that after the controller 150 receives the loop configuration information of the wiring harness assembly, the loop control module 151 in the controller 150 controls the on-off of the connector 120 on the wiring harness monomer 100 according to the loop configuration information, thereby constructing a loop that meets the requirements for the wiring harness assembly. In this embodiment, there may be multiple lines in the cable 110 and the connector 120 for transmitting different signals and / or electrical energy. In this embodiment, after multiple wiring harness monomers 100 are connected to form a wiring harness assembly, the controller 150 of one of the wiring harness monomers 100 can be used as the main controller for calculation and decision-making. The controllers 150 of other harness units 100 serve as auxiliary controllers for executing commands issued by the main controller.

[0042] like Figure 8 As shown, in this embodiment, the controller 150 is electrically connected to the cable 110 of the wiring harness monomer 100; The controller 150 further includes a parameter configuration module 152 for detecting the device type of the electrical device connected to each wiring harness monomer 100 in the wiring harness assembly, and configuring corresponding electrical parameters for each wiring harness monomer 100 according to the device type.

[0043] It should be noted that the electrical parameters include technical indicators such as voltage, current, power, and signal transmission rate that describe the operating requirements of electrical equipment.

[0044] Since the electrical parameters of the electrical devices connected to different harness monomers 100 may be different in actual application scenarios, in order to improve the adaptation efficiency of the harness assembly for different vehicle models and configurations. The controller 150 of the embodiment of the present application also includes a parameter configuration module 152. The controller 150 can detect the device type of the electrical device connected to each harness monomer 100 in the harness assembly through the parameter configuration module 152. Then, according to the device type, a predetermined electrical parameter mapping table is queried to obtain the electrical parameters corresponding to the device type, and each line of the cable 100 in each harness monomer 100 is configured based on the electrical parameters.

[0045] Therefore, after the wiring harness assembly is connected to each electrical device, the controller 150 can provide corresponding electrical conditions for each electrical device through the parameter configuration module 152 to meet the operation requirements of different electrical devices, thereby effectively improving the adaptation efficiency of the wiring harness assembly for different vehicle models and configurations.

[0046] In addition, the present application embodiment provides a control method for a wiring harness assembly, referring to Fig. 9 , Fig. 9 This is a flow chart of an embodiment of a control method for a wiring harness assembly of the present application.

[0047] In this embodiment, the control method of the wiring harness assembly includes steps S10 to S20: Step S10, obtaining loop configuration information of the wiring harness assembly, wherein the loop configuration information includes a connection relationship between each wiring harness monomer in the wiring harness assembly; Step S20, controlling the on and off of the connector on the wiring harness unit according to the connection relationship.

[0048] It should be noted that the executor of this embodiment is the controller in the wiring harness assembly, and the controller can be a component with processing capabilities such as MCU (Micro-Controller), MPU (Micro-Processor Unit), FPGA (Field-Programmable Gate Array), etc.

[0049] In addition, it should be noted that the loop configuration information includes the connection relationship between each wiring harness monomer in the wiring harness assembly, that is, whether each wiring harness monomer in the wiring harness assembly needs to be connected.

[0050] This embodiment can obtain the loop configuration information of the wiring harness assembly, wherein the loop configuration information includes the connection relationship between each wiring harness monomer in the wiring harness assembly, and then the on and off of the connector on the wiring harness monomer can be controlled according to the connection relationship. Exemplarily, the wiring harness assembly includes a wiring harness monomer 1, a wiring harness monomer 2, and a wiring harness monomer 3 connected in sequence, wherein the connection relationship in the loop configuration information is that the wiring harness monomer 2 and the wiring harness monomer 3 are connected, then this embodiment can control the disconnection of the connector on the wiring harness monomer 1 and the wiring harness monomer 2. It can be understood that the disconnection of the electrical connection of the connector can be a physical disconnection, that is, the connector of the wiring harness monomer 1 is no longer connected to the connector of the wiring harness monomer 2, and thus there is no electrical connection between the wiring harness monomer 1 and the wiring harness monomer 2 and the wiring harness monomer 3. Of course, the disconnection of the electrical connection of the connector can also be a disconnection only in the electrical connection, that is, the connection between the connector of the wiring harness monomer 1 and the wiring harness monomer 2 is still physically connected together, but no signal and / or electrical energy is transmitted. In this way, this embodiment can directly reconnect the connectors between the wiring harness monomers while the connection relationship of the wiring harness monomers in the wiring harness assembly changes.

[0051] In one embodiment, the control method of the wiring harness assembly further includes: Step S30, after the wiring harness assembly is connected to each electrical device, the electrical device connected to each wiring harness monomer in the wiring harness assembly is detected to obtain the device type of the electrical device connected to each wiring harness monomer; Step S40: configuring corresponding electrical parameters for each wiring harness monomer according to the device type.

[0052] It should be noted that the electrical parameters include technical indicators such as voltage, current, power, and signal transmission rate that describe the operating requirements of electrical equipment.

[0053] Since in actual application scenarios, the electrical parameters of the electrical devices connected to different harness monomers in the harness assembly may be different, in order to improve the adaptation efficiency of the harness assembly for different vehicle models and configurations. In this embodiment, after the harness assembly is connected to each electrical device, it can communicate with the vehicle's diagnostic interface to detect the device type of the electrical device connected to each harness monomer in the harness assembly. Exemplarily, this embodiment can pre-construct a predetermined electrical parameter mapping table that describes the correspondence between different device types and electrical parameters. Furthermore, this embodiment can query the predetermined electrical parameter mapping table according to the device type of the electrical device connected to each harness monomer in the harness assembly, obtain the electrical parameters corresponding to the device type, and configure each line of the cable 100 in each harness monomer 100 based on the electrical parameters.
