Description

Technical Field

[0001] The present invention relates to a wiring harness connection device and a connection method for an intelligent gateway of a new energy vehicle. Background Art

[0002] New energy vehicles, powered by clean energy like electricity, are environmentally friendly and low-cost, representing a new trend in future mobility. Compared to traditional fuel-powered vehicles, new energy vehicles boast significant power reserves, enabling them to provide robust power support for power-hungry intelligent systems.

[0003] The intelligence of new energy vehicles relies on powerful computing power. Within this intelligent module, the gateway is a crucial component, fulfilling multiple critical functions and roles. As a potential target for cyberattacks, connected vehicles face unprecedented challenges in vehicle control, passenger safety, and data protection. This requires a robust protection mechanism—an industrialized intelligent security gateway. Acting like a firewall within the vehicle's nervous system, it ensures secure communication between external networks and internal vehicle systems, preventing malicious attacks and safeguarding core systems from disruption.

[0004] The automotive gateway control module is a core component of this complex system. Acting as a data transmission bridge, it effectively routes communication data between diverse networks such as CAN, LIN, MOST, and FlexRay. It not only connects various nodes within the vehicle but also ensures the efficient and secure flow of information between different networks, achieving functional domain isolation and protecting sensitive information and critical systems from threats. It connects key components such as the battery, motor, and control system to ensure the proper operation of the vehicle. Its importance lies in ensuring stable power transmission and accurate signal transmission, which are crucial to vehicle safety and performance, and are a key foundation for the reliable operation of new energy vehicles. The connection between the gateway and these key components relies primarily on a detachable wiring harness connection structure, making the stability of the wiring harness connection crucial.

[0005] In conventional wiring harness connection devices, to ensure smooth docking of the connecting terminals, the two connecting terminals are usually designed with one convex and one concave. However, before connection, the protruding connecting terminal is generally exposed. As the connection is transferred during operation, the connecting terminals are prone to wear and tear, or foreign matter such as dust and water are adhered to them, resulting in poor stability of the final electrical connection. Moreover, the connecting terminals are usually made of copper materials such as brass, phosphor bronze, and beryllium copper. Once wear occurs, the contact resistance increases, which leads to unstable connection, reduced signal transmission quality, and even short circuit or open circuit in severe cases.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] In addition, when an element in the present invention is referred to as being "disposed on" or "positioned on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only embodiment.

[0044] See also Figures 1-10 In an embodiment of the present invention, a wiring harness connection device for a new energy vehicle intelligent gateway includes a first connector 1 and a second connector 2 adapted to each other, each of which is provided with a first connection terminal 3 and a second connection terminal 4, and further includes:

[0045] an elastic energy storage mechanism, disposed in the first connector 1 and connected to the first connection terminal 3, capable of causing the first connection terminal 3 to move along the axial direction of the first connector 1, the elastic energy storage mechanism cooperating with an elastic limiting mechanism disposed in the first connector 1;

[0046] The locking mechanism is provided in multiple groups at equal intervals along the circumference of the first connector 1, and is used to lock the first connector 1 and the second connector 2 after the line is connected, and the locking mechanism also cooperates with the blocking mechanism provided on the second connector 2.

[0047] In detail, when performing the wiring harness connection operation, the staff firmly holds the first connector 1 and the second connector 2 with both hands, and accurately connects the two. At the same time, the locking mechanism responds quickly, firmly fixing the docking state of the first connector 1 and the second connector 2 to ensure the stability of the connection. In this critical process, the elastic limiting mechanism is accurately triggered, and the limiting constraints on the elastic energy storage mechanism are immediately released. This action effectively prompts the first connection terminal 3 to move along the axial direction of the first connector 1, thereby making the first connection terminal 3 and the second connection terminal 4 complete close contact, thereby achieving stable electrical connection of the wiring harness, providing strong protection for subsequent circuit operation;

[0048] Furthermore, the locking mechanism further prompts the blocking mechanism to be triggered in a timely manner. The blocking mechanism then performs its vital function, completely sealing the gap at the connection between the first connector 1 and the second connector 2. This tight sealing measure greatly improves the sealing performance of the first connector 1 and the second connector 2 after docking, creating a solid protective barrier for the connection. This effectively prevents external environmental factors, such as dust, moisture, and impurities, from adversely affecting the first and second connection terminals 3 and 4, thus comprehensively ensuring the reliability and durability of the wiring harness connection and the stable operation of the circuit system.

[0049] Please refer again Figure 5 A wire barrel 9 is fixedly provided in the first connector 1, and a spring wire is provided in the wire barrel 9. One end of the spring wire is connected to the first connecting terminal 3, and the other end is arranged on the bottom wall of the first connector 1 and connected to the signal transmission harness.

[0050] Furthermore, the spring wire, also known as spiral wire, is a unique combination of elasticity and flexibility, resulting in excellent mechanical properties. Specifically, spring wire can easily withstand high bending and twisting without breaking, thanks to its unique structural design, which allows it to maintain a good electrical connection even under repeated mechanical stress.

[0051] In many fields, spring wires are highly favored due to their unique advantages and are widely used in various devices that need to be frequently moved or extended, such as retractable power cords, data transmission cables, and connecting cables of various portable electronic devices. In the specific application scenarios involved in this application, spring wires play a vital role, and they can provide strong support for the movement of the first connecting terminal 3. When the first connecting terminal 3 needs to move along the axial direction of the first connector 1, the spring wire can flexibly stretch and shrink to ensure that the first connecting terminal 3 always maintains a stable electrical connection during the movement, and there will be no poor contact or open circuit due to the movement of the wiring harness. This stable connection performance is crucial to ensuring the reliability and safety of the entire circuit system, especially in some application scenarios that require high electrical connection stability. The use of spring wires can significantly improve the performance of the device and user experience.

[0052] Please refer again Figure 6 and Figure 9Two assembly plates 5 are provided within the first connector 1. The elastic energy storage mechanism includes two cross bars 6 slidably mounted on the two assembly plates 5. The head ends of the two cross bars 6 are fixedly connected to a clamp 10. The first connection terminal 3 is mounted within the clamp 10. The tail ends of the cross bars 6 cooperate with the elastic limiting mechanism. Both cross bars 6 are provided with an elastic boosting assembly. The elastic boosting assembly includes a ring body 8 provided on the cross bar 6 and a first cylindrical spring 7 sleeved around the outer circumference of the cross bar 6. One end of the first cylindrical spring 7 is connected to the ring body 8 and the other end is connected to the assembly plate 5. The elastic limiting mechanism can cause the first cylindrical spring 7 to rebound or compress.

[0053] Specifically, when the first connector 1 and the second connector 2 are separated, the elastic limiting mechanism can accurately limit the end of the crossbar 6 away from the clamp 10. At this time, the first cylindrical spring 7 is in a compressed state, and accordingly, the first connection terminal 3 is located inside the first connector 1, and the first connector 1 effectively accommodates the first connection terminal 3.

[0054] In conventional wiring harness connection devices, to ensure smooth docking of the connecting terminals, the two connecting terminals are usually designed with one convex and one concave. However, before connection, the protruding connecting terminal is generally exposed. As the connection is transferred during operation, the connecting terminals are prone to wear and tear, or foreign matter such as dust and water are adhered to them, resulting in poor stability of the final electrical connection. Moreover, the connecting terminals are usually made of copper materials such as brass, phosphor bronze, and beryllium copper. Once wear occurs, the contact resistance increases, which leads to unstable connection, reduced signal transmission quality, and even short circuit or open circuit in severe cases.

[0055] However, in the present application, the second connecting terminal 4 is recessed in the second connecting head 2. This design can effectively avoid wear problems. At the same time, the first connecting terminal 3 is movably arranged in the first connecting head 1. When the first connecting head 1 and the second connecting head 2 are in an unconnected state, under the action of the elastic limiting mechanism, the first connecting terminal 3 can be received in the first connecting head 1, thereby avoiding wear and contamination problems that may be caused by exposure to the outside. After the first connecting head 1 and the second connecting head 2 are docked, the first cylindrical spring 7 can rebound quickly, so that the first connecting terminal 3 automatically pops out from the first connecting head 1 into the second connecting head 2, and achieves stable and reliable docking with the second connecting terminal 4, ensuring the stability of the electrical connection and the quality of signal transmission.

[0056] Please refer again Figure 7 、 Figure 9 as well as Figure 10The ends of the two crossbars 6 away from the clamp 10 are each fixedly connected to a follower plate 20 via a connecting arm 21. The follower plate 20 is provided with an inclined surface 2001. The elastic limiting mechanism includes an elastic telescopic component provided in the first connector 1 and an opening and closing structure connected to the elastic telescopic component. The opening and closing structure can cooperate with the follower plate 20 via the inclined surface 2001. The opening and closing structure includes a guide beam 16 provided in the first connector 1 and two follower seats 17 symmetrically slidably provided on the guide beam 16. The bottom of the follower seat 17 is provided with a roller 19, which abuts the inclined surface 2001. The follower seat 17 is also provided with a transmission plate 18, which cooperates with the elastic telescopic component. The elastic telescopic component includes a guide cylinder 11 arranged in the first connecting head 1 and axially parallel to the first connecting head 1, a telescopic rod 12 slidingly fitted with the guide cylinder 11, and a second cylindrical spring 14 arranged in the guide cylinder 11 and sleeved on the outer periphery of the telescopic rod 12, one end of the second cylindrical spring 14 is connected to the inner wall of the guide cylinder 11, and the other end is connected to the frustum 13 arranged at the head end of the telescopic rod 12; wherein, the end of the second connecting head 2 is provided with a top rod 201 adapted to the frustum 13, the tail end of the telescopic rod 12 is provided with a follower arm 15, and the two ends of the follower arm 15 are respectively provided with a boss 1501, and each of the two transmission plates 18 is provided with an inclined groove 1801 adapted to the boss 1501, and the boss 1501 extends into the inclined groove 1801 and is slidably connected to the transmission plate 18.

[0057] When the first connector 1 and the second connector 2 are docked, the push rod 201 will act on the circular table 13. As the docking progresses, the push rod 201 will push the telescopic rod 12 toward the inner direction of the first connector 1 through the circular table 13, and the second cylindrical spring 14 is compressed. Accordingly, the follower arm 15 and the two bosses 1501 move together with the telescopic rod 12, and the bosses 1501 slide with the transmission plate 18 through the inclined groove 1801. As a result, the two follower seats 17 slide away from each other on the guide beam 16, and the two rollers 19 move away from each other. During this process, the first cylindrical spring 7 will gradually rebound, prompting the cross bar 6 to push through the hoop 10 The first connecting terminal 3 gradually moves along the axial direction of the first connecting head 1 toward the outside direction of the first connecting head 1. After the end faces of the first connecting head 1 and the second connecting head 2 are in contact, the roller 19 is separated from the inclined surface 2001. At this time, under the action of the elastic support force of the first cylindrical spring 7, the first connecting terminal 3 can apply a certain pressure to the second connecting terminal 4, so that the contact surface can be made tighter, the contact gap can be reduced, and the contact resistance can be reduced, thereby ensuring the stability of the electrical connection and the quality of signal transmission. In addition, during the driving of the vehicle, a certain degree of bumps will be generated. Under the elastic support of the first cylindrical spring 7, it can play a certain vibration reduction role to ensure the stability of the electrical connection state.

[0058] It should be emphasized that the elastic potential energy of the second cylindrical spring 14 is greater than the elastic potential energy of the first cylindrical spring 7. Therefore, when the user releases the docking state between the first connector 1 and the second connector 2, the second cylindrical spring 14 will rebound, and the two follower seats 17 slide close to each other on the guide beam 16. The roller 19 acts on the inclined surface 2001 again, thereby prompting the follower plate 20 to give way, that is, the follower plate 20 pulls the first connecting terminal 3 toward the inside of the first connector 1 through the connecting arm 21, the cross bar 6 and the clamp 10 to shrink.

[0059] Please refer again Figure 2 and Figure 3 The blocking mechanism includes a fixing ring 26 arranged at the end of the second connector 2. The fixing ring 26 is hollow inside and has an annular groove 2601 on the inner wall. An airbag is provided inside the fixing ring 26, and the airbag is connected to the air bag 28 provided on the outer wall of the second connector 2. The fixing ring 26 is also provided with a triangular block 27 that cooperates with the locking mechanism.

[0060] Please refer again Figure 8The locking mechanism includes a fixed arm 22 provided on the outer wall of the first connector 1, two connecting posts 24 slidably provided on the fixed arm 22, and a pressing plate 23 fixedly connecting the two connecting posts 24, and the pressing plate 23 cooperates with the blocking mechanism;

[0061] Among them, the side of the pressure plate 23 is also formed with an inclined portion 2301 that cooperates with the triangular block 27, and the outer periphery of the connecting column 24 is sleeved with a third cylindrical spring 25, and the two ends of the third cylindrical spring 25 are respectively connected to the pressure plate 23 and the fixed arm 22.

[0062] When connecting the first connector 1 and the second connector 2, the inclined portion 2301 is aligned with the inclined surface on the triangular block 27. As the first connector 1 is pushed, the inclined portion 2301 and the triangular block 27 are slidably matched, and the pressure plate 23 gives way and gradually moves closer to the fixed arm 22. The third cylindrical spring 25 is compressed. After the pressure plate 23 passes over the fixing ring 26 (that is, the pressure plate 23 reaches the side of the fixing ring 26 away from the first connector 1), the third cylindrical spring 25 rebounds, and then the fixing ring 26 limits the pressure plate 23, thereby achieving docking between the first connector 1 and the second connector 2. The state is maintained, and when the third cylindrical spring 25 rebounds, the pressure plate 23 will apply pressure to the airbag 28, and the gas in the airbag 28 is filled into the airbag. After the airbag expands, it will overflow out of the annular groove 2601, covering the docking gap between the first connector 1 and the second connector 2, greatly improving the sealing performance of the first connector 1 and the second connector 2 after docking, just like building a solid protective barrier for the connection part, effectively avoiding external environmental factors such as dust, moisture, impurities, etc., which have adverse effects on the first connection terminal 3 and the second connection terminal 4, and comprehensively guaranteeing the reliability and durability of the wiring harness connection, and ensuring the stable operation of the circuit system.

[0063] As another embodiment of the present invention, a wiring harness connection method for a new energy vehicle intelligent gateway is also proposed, using the connection device, comprising the following steps:

[0064] Step 1: Hold the first connector 1 and the second connector 2 and align them for insertion;

[0065] Step 2: The elastic limiting mechanism is triggered, prompting the elastic energy storage mechanism to release elastic potential energy, so that the first connecting terminal 3 moves along the circumference of the first connector 1 and contacts the second connecting terminal 4;

[0066] In step three, the locking mechanism is triggered to lock the docking state of the first connector 1 and the second connector 2 , and the blocking mechanism blocks the connection gap between the first connector 1 and the second connector 2 .

[0067] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0068] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
