In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0030] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0031] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0032] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0033] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0035] As cars become more and more intelligent, the functions on the doors are also increasing. Functions such as door locks, glass lifts and switches are all driven by the body controller. Therefore, the door wiring harness needs to be connected to the body wiring harness or electrical controller so that the body controller or electrical controller can send a drive signal to the door wiring harness to drive the door components to achieve the corresponding functions.

[0036] The existing front door harness usually adopts two docking methods: one is that the door harness and the body harness are connected at the side wall through a docking connector; the other is that the door harness passes through the side wall into the cab and is connected to the controller or connected through a docking connector in the room. The two forms are usually related to the position of the controller that controls the electrical parts in the front door. For the electrical controller arranged in the cab, especially near the A-pillar, the second form is more cost-effective. However, this solution is often accompanied by some space problems. For example, the functions such as the speakers, side impact sensors, and camera lines in the front door are usually not controlled by the controller of the door lock, and need to be wired to electrical components such as power amplifiers, airbag controllers, and parking controllers. These electrical controllers are usually far away from the A-pillar, and the door harness cannot be directly connected to them, and need to be connected to the body harness through docking. Therefore, compared with Scheme 1, Scheme 2 saves the docking at the side wall, but needs to add docking of the door speakers, side impact sensors, cameras, etc. in the room. The space near the A-pillar has always been relatively tight, and it is also necessary to take into account the operational feasibility during assembly, which often makes the arrangement of docking connectors a problem.

[0037] In summary, the present application provides a door wiring harness connection assembly and a vehicle, so that the door wiring harness of the door lock and other devices that can be directly connected to the controller can be passed into the cab, while the loop that needs to be docked with the body wiring harness still uses the space at the side panel for docking, and through some structural designs, internal separation and external unified sealing are formed, thereby achieving dual optimization of cost and space.

[0038] Referring to FIG. 1 and FIG. 2 , an embodiment of the present application provides a vehicle door harness connection assembly, including a mounting assembly 2 and a vehicle door harness assembly 1. The vehicle door harness assembly 1 is arranged on the mounting assembly 2, and is used to connect the vehicle body controller and the vehicle door component, so that the vehicle body controller can send a driving signal through the vehicle door harness assembly 1 to drive the vehicle door component to realize a corresponding function. The mounting assembly 2 is used to be installed on the vehicle door to assist the vehicle door harness assembly 1 in connecting the vehicle body controller and the vehicle door component.

[0039] In the specific configuration, the mounting assembly 2 is provided with a docking device 3. It is understandable that the docking device 3 is a device for achieving electrical connection, which can play the role of a high current probe by directly pressing on the contact surface. Specifically, the mounting assembly 2 is provided with a first mounting opening, the docking device 3 is arranged in the first mounting opening, and the docking device 3 has a first docking portion and a second docking portion symmetrically arranged along the penetration direction of the first mounting opening.

[0040] The door harness assembly 1 includes a door harness bus 11, a first door harness branch 12, and a second door harness branch 13. The first door harness branch 12 is arranged on the door harness bus 11 and docked with the docking device 3. The door harness bus 11 can be connected to the body harness 14 with the docking device 3 through the first door harness branch 12, so that the electrical controller far from the A-pillar of the car can send a driving signal to the door harness bus 11 through the body harness 14 and the first door harness branch 12, and drive the door components to realize corresponding functions.

[0041] Specifically, referring to Figures 1 to 3, the first door wiring harness branch 12 is connected to the first docking part of the docking connector 3, so that when the docking connector 3 of the body wiring harness 14 is connected to the second docking part of the docking connector 3, the circuit connection between the first door wiring harness branch 12 and the body wiring harness 14 can be realized, so that the electrical controller far away from the A-pillar of the car can send a drive signal to the door wiring harness bus 11 through the body wiring harness 14 and the first door wiring harness branch 12, thereby driving the door components to realize corresponding functions.

[0042] The second door harness branch line 13 is passed through the mounting assembly 2, and one end of the second door harness branch line 13 is connected to the door harness bus 11, and the other end of the second door harness branch line 13 is provided with a connector 4, which is used to connect to the electrical controller. The door harness bus 11 can be connected to the electrical controller closer to the A-pillar of the vehicle through the connector 4 on the second door harness branch line 13, so that the electrical controller farther from the A-pillar of the vehicle can directly send a driving signal to the door harness bus 11 through the second door harness branch line 13, and drive the door components to realize corresponding functions.

[0043] In addition, in order to ensure the stability of the second door wiring harness branch 13 on the mounting assembly 2, a fixing ring 17 is provided on the second door wiring harness branch 13, and a fixing protrusion is provided on the mounting assembly 2, and the fixing ring 17 is simultaneously wrapped around the second door wiring harness branch 13 and the mounting assembly 2 to improve the connection stability between the second door wiring harness branch 13 and the mounting assembly 2.

[0044] In summary, when the door harness connection assembly of the present application is used, the mounting assembly 2 can be installed on the door, and by connecting the door harness bus 11 with the first door harness branch 12 and the second door harness branch 13, the door harness bus 11 can be connected to the body harness 14 with the docking device 3 through the first door harness branch 12, so that the electrical controller far from the A-pillar of the car can send a drive signal to the door harness bus 11 through the body harness 14 and the first door harness branch 12, so as to drive the door components to realize the corresponding functions; at the same time, the door harness bus 11 can be connected to the vehicle body harness 14 and the first door harness branch 12. 1 can be connected to an electrical controller closer to the A-pillar of the vehicle through the connector 4 on the second door harness branch line 13, so that the electrical controller closer to the A-pillar of the vehicle can directly send a driving signal to the door harness bus 11 through the second door harness branch line 13 to drive the door component to realize the corresponding function. By reasonably allocating the first door harness branch line 12 and the second door harness branch line 13, the door harness bus 11 can be connected to the electrical controller near the A-pillar of the vehicle and the electrical controller farther from the A-pillar of the vehicle while taking into account the assembly feasibility and cost.

[0045] It is understandable that the A-pillar of a car, also known as the A-pillar, is a supporting structure connecting the two sides of the vehicle's front windshield to the roof, and is located between the engine compartment and the cockpit. The A-pillar plays a vital role in the safety structure of the car, especially in a head-on collision, it bears the brunt of the impact, protecting the passenger compartment from deformation and preventing wheels, suspension, etc. from invading the passenger compartment. The electrical controllers near the A-pillar mainly include domain controllers related to the smart cockpit, such as car locks and window lift switches. The electrical controllers farther away from the A-pillar of the car mainly include power amplifiers, airbag controllers, parking controllers and other electrical controllers.

[0046] Referring to FIGS. 1 to 3 , in one embodiment, the door harness connection assembly further includes a body harness 14, and a docking head 15 matching the docking device 3 is provided on the body harness 14. Specifically, the body harness 14 is spaced apart from the second door harness branch line 13, and a docking head 15 capable of docking with the docking device 3 is provided on the body harness 14, so that the body harness 14 is connected to the docking device 3 through the docking head 15, so that the door harness bus 11 can be connected to the body harness 14 through the first door harness branch line 12 and the docking device 3, and then the electrical controller near the A-pillar of the automobile can send a driving signal to the door harness bus 11 through the body harness 14 and the first door harness branch line 12, so as to drive the door components to realize corresponding functions.

[0047] Referring to Fig. 1, Fig. 2 and Fig. 4, in one embodiment, the mounting assembly 2 includes a mounting member 21 and a protective member 22, and the mounting member 21 is provided with a first mounting opening for mounting the docking device 3, and a second mounting opening for passing the second door harness branch line 13. The penetration direction of the first mounting opening is parallel to the penetration direction of the second mounting opening, so that the body harness 14 can be arranged in parallel with the second door harness, thereby saving installation space while ensuring the use effect.

[0048] The protective member 22 is arranged on the mounting member 21 and is connected with the first mounting port and the second mounting port. The connection part between the door wiring harness bus 11, the first door wiring harness branch line 12 and the second door wiring harness branch line 13 is located inside the protective member 22, so that the protective member 22 can protect the connection part between the door wiring harness bus 11, the first door wiring harness branch line 12 and the second door wiring harness branch line 13.

[0049] Specifically, the protective member 22 includes a fixing portion 221 and a corrugated telescopic tube 222. The mounting member 21 and the fixing portion 221 are respectively arranged at both ends of the corrugated telescopic tube 222 and are both connected to the corrugated telescopic tube 222.

One end of the door harness bus 11 passes through the fixing portion 221 and extends into the corrugated telescopic tube 222, so that the corrugated telescopic tube 222 can protect the door harness bus 11 while ensuring that the door harness bus 11 is normally bent and used. The first door harness branch line 12 is located inside the corrugated telescopic tube 222, so that the corrugated telescopic tube 222 can protect the first door harness branch line 12 while ensuring that the first door harness branch line 12 is normally bent and used.

[0050] Referring to Fig. 1, Fig. 2 and Fig. 4, in one embodiment, the mounting member 21 includes a plastic component 211 and a flexible component 212, the flexible component 212 is connected to the protective member 22, the plastic component 211 is arranged in the flexible component 212, and the first mounting opening and the second mounting opening are both arranged on the plastic component 211. By dividing the mounting member 21 into the plastic component 211 and the flexible component 212, the mounting member 21 can be firmly connected to the docking device 3 while ensuring a sealing effect with the vehicle door after installation.

[0051] Specifically, the docking connector 3 and the plastic component 211 are integrally formed to facilitate the production of the docking connector 3 and the plastic component 211 while ensuring the stability of the connection between the mounting member 21 and the docking connector 3 .

[0055] Specifically, a first snap-fit ​​structure is provided on the first connecting member 213, and a second snap-fit ​​structure is provided on the second connecting member 16. When the docking joint 15 is docked on the docking connector 3, the first snap-fit ​​structure can be snap-fitted with the second snap-fit ​​structure to achieve a firm connection between the docking joint 15 and the mounting member 21, thereby achieving a firm docking effect between the docking joint 15 and the docking connector 3 and preventing the docking joint 15 from falling off the docking connector 3.
