Description

Technical Field

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

[0002] New energy vehicles are powered by clean energy such as electricity, which is environmentally friendly and has low usage costs, representing a new trend for future travel. Compared with traditional fuel vehicles, new energy vehicles can provide strong power supply support for intelligent systems with high power consumption due to their powerful power storage capabilities.

[0003] The intelligence of new energy vehicles relies on powerful intelligent computing power. Among the intelligent modules, the gateway is a crucial component that undertakes multiple key functions and roles. As a potential target of cyberattacks, intelligent connected vehicles face unprecedented challenges in vehicle control, passenger safety, and data protection. This requires a robust protection mechanism - an industrial intelligent security gateway, which acts as a firewall in the vehicle's nervous system, ensuring secure communication between the external network and the vehicle's internal system, preventing malicious attacks, and maintaining the core system from being disturbed.

[0004] The vehicle gateway control module is the core component of this complex system. As a bridge for data transmission, it plays a role in effectively routing communication data between different networks such as CAN, LIN, MOST, and FlexRay. It not only connects various nodes inside the vehicle but also ensures the efficient and secure flow of information between different networks, realizes functional domain isolation, and protects sensitive information and key systems from threats. It connects key components such as the battery, motor, and control system to ensure the normal operation of the vehicle. Its importance lies in ensuring stable power transmission and accurate signal transmission, which is crucial for vehicle driving safety and performance, and is the key foundation for the reliable operation of new energy vehicles. The connection between the gateway and each key component basically relies on a detachable wire harness connection structure, and the stability of the wire harness connection is of utmost importance.

[0005] In a conventional wire harness connection device, in order to ensure the smooth docking of the connection terminals, the two connection terminals are usually designed with a convex and a concave structure. However, before connection, the convex connection terminal is generally exposed. During the transfer in the operation process, the connection terminal is extremely prone to wear, or adhere to foreign matters such as dust and water, resulting in poor stability of the final electrical connection. Moreover, the connection terminal usually uses copper materials such as brass, phosphor bronze, and beryllium copper. Once worn, the contact resistance will increase, leading to unstable connection, decreased signal transmission quality, and even short circuit or open circuit in severe cases.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In addition, an element in the present invention is referred to as "being disposed on" or "arranged on" another element, and it can be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0031] Please refer to Figures 1-10 , in an embodiment of the present invention, a wire harness connection device for a new energy vehicle intelligent gateway includes a first connector 1 and a second connector 2 that are adapted to each other. A first connection terminal 3 and a second connection terminal 4 are respectively arranged inside the two, and further includes: An elastic energy storage mechanism is arranged inside the first connector 1, connected to the first connection terminal 3, and capable of causing the first connection terminal 3 to move axially along the first connector 1. The elastic energy storage mechanism cooperates with an elastic limit mechanism arranged inside the first connector 1; A locking mechanism is provided in multiple groups at equal intervals along the circumference on the first connector 1, and is used to lock the first connector 1 and the second connector 2 after the circuit is connected. The locking mechanism also cooperates with a blocking mechanism arranged on the second connector 2.

[0032] Specifically, when performing the wire harness connection operation, the staff firmly hold the first connector 1 and the second connector 2 with both hands respectively, and accurately dock the two. At the same time, the locking mechanism responds quickly and firmly fixes the docking state of the first connector 1 and the second connector 2 to ensure the stability of the connection. In this key process, the elastic limit mechanism is accurately triggered, and immediately releases the limit restraint on the elastic energy storage mechanism. This action effectively causes the first connection terminal 3 to move axially along the first connector 1, so that the first connection terminal 3 and the second connection terminal 4 are in close contact, thereby realizing the stable power connection of the wire harness and providing a strong guarantee for the subsequent circuit operation; Moreover, the locking mechanism will further cause the blocking mechanism to be triggered in time. The blocking mechanism then plays its important role and completely seals the gap at the connection between the first connector 1 and the second connector 2. Through this strict sealing measure, the sealing performance after the docking of the first connector 1 and the second connector 2 is greatly improved, just like building a solid protective barrier for the connection part, effectively avoiding the adverse effects of external environmental factors such as dust, moisture, impurities, etc. on the first connection terminal 3 and the second connection terminal 4, comprehensively ensuring the reliability and durability of the wire harness connection, and ensuring the stable operation of the circuit system.

[0033] Please refer to again Figure 5, a wire placing cylinder 9 is fixedly arranged inside the first connector 1. A spring wire is arranged inside the wire placing cylinder 9. One end of the spring wire is connected to the first connection terminal 3, and the other end is arranged on the bottom wall of the first connector 1 and connected to a signal transmission wire harness.

[0034] Furthermore, the spring wire, also known as a helical wire, is a unique wire that ingeniously combines elasticity and stretchability and has excellent mechanical properties. Specifically, the spring wire can easily withstand high bending and torsion without being easily damaged. This is due to its special structural design, which enables it to maintain good electrical connection performance under repeated mechanical stresses.

[0035] In many fields, the spring wire is highly favored because of these unique advantages and is widely used in various devices that require frequent movement or stretching, such as retractable power cords, data transmission lines, and connecting wires of various portable electronic devices. In the specific application scenario involved in this application, the spring wire plays a crucial role. It can provide strong support for the movement of the first connection terminal 3. When the first connection terminal 3 needs to move along the axial direction of the first connector 1, the spring wire can flexibly stretch and contract to ensure that the first connection terminal 3 always maintains a stable electrical connection during the movement and will not have poor contact or open circuit due to the movement of the wire harness. This stable connection performance is crucial for ensuring the reliability and safety of the entire circuit system. Especially in some application scenarios with high requirements for electrical connection stability, the application of the spring wire can significantly improve the performance of the device and the user experience.

[0036] Please refer to again Figure 6 and Figure 9 , two mounting plates 5 are arranged inside the first connector 1. The elastic energy storage mechanism includes two cross bars 6 respectively sliding on the two mounting plates 5. The first ends of the two cross bars 6 are fixedly connected with a hoop 10. The first connection terminal 3 is installed inside the hoop 10. The tail ends of the cross bars 6 cooperate with the elastic limit mechanism, and elastic boosting components are arranged on both cross bars 6. The elastic boosting component includes a ring body 8 arranged on the cross bar 6 and a first cylindrical spring 7 sleeved on the outer periphery 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 mounting plate 5, and the elastic limit mechanism can cause the first cylindrical spring 7 to rebound or compress.

[0037] Specifically, when the first connector 1 and the second connector 2 are in a separated state, the elastic limiting mechanism can accurately limit one end of the cross bar 6 away from the hoop 10. At this time, the first cylindrical spring 7 is in a compressed state. Correspondingly, the first connection terminal 3 is located inside the first connector 1, and the first connector 1 realizes the effective storage function for the first connection terminal 3.

[0038] In a conventional wire harness connection device, in order to ensure the smooth docking of connection terminals, the two connection terminals are usually designed with a convex and a concave structure. However, before connection, the protruding connection terminal is generally exposed. During the transfer in the operation process, the connection terminal is extremely prone to wear, or adhesion of foreign matters such as dust and water, resulting in poor stability of the final electrical connection. Moreover, the connection terminal usually uses copper materials such as brass, phosphor bronze, and beryllium copper. Once wear occurs, the contact resistance will increase, leading to unstable connection, decreased signal transmission quality, and even short circuit or open circuit in severe cases.

[0039] However, in this application, the second connection terminal 4 is recessed in the second connector 2, and this design can effectively avoid the wear problem. At the same time, the first connection terminal 3 is movably arranged inside the first connector 1. When the first connector 1 and the second connector 2 are in an unconnected state, under the action of the elastic limiting mechanism, the first connection terminal 3 can be stored inside the first connector 1, thus avoiding the wear and pollution problems that may be caused by being exposed. After the first connector 1 and the second connector 2 are docked, the first cylindrical spring 7 can quickly rebound, causing the first connection terminal 3 to automatically pop out from the first connector 1 into the second connector 2 and realizing stable and reliable docking with the second connection terminal 4, ensuring the stability of the electrical connection and the quality of signal transmission.

[0040] Please refer to again Figure 7 、 Figure 9 and Figure 10, one end of each of the two cross bars 6 away from the hoop 10 is fixedly connected with a follower plate member 20 through a connecting arm 21, and an inclined surface 2001 is provided on the follower plate member 20; the elastic limiting mechanism includes an elastic telescopic assembly arranged in the first connector 1 and a toggling structure connecting the elastic telescopic assembly, and the toggling structure can cooperate with the follower plate member 20 through the inclined surface 2001. The toggling structure includes a guiding beam 16 arranged in the first connector 1 and two follower seats 17 symmetrically sliding on the guiding beam 16. A roller 19 is provided at the bottom of the follower seat 17, and the roller 19 abuts against the inclined surface 2001. A transmission plate member 18 is further arranged on the follower seat 17, and the transmission plate member 18 cooperates with the elastic telescopic assembly. The elastic telescopic assembly includes a guiding cylinder 11 arranged in the first connector 1 and parallel to the axis of the first connector 1, a telescopic rod 12 slidably sleeved with the guiding cylinder 11, and a second cylindrical spring 14 arranged in the guiding 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 guiding cylinder 11, and the other end is connected to a frustum 13 arranged at the head end of the telescopic rod 12; wherein, a ejector rod 201 adapted to the frustum 13 is arranged at the end of the second connector 2, a follower arm 15 is arranged at the tail end of the telescopic rod 12, two convex columns 1501 are respectively arranged at both ends of the follower arm 15, and an inclined groove 1801 adapted to the convex column 1501 is arranged on each of the two transmission plate members 18, and the convex column 1501 extends into the inclined groove 1801 and is slidably connected with the transmission plate member 18.

[0041] When the first connector 1 and the second connector 2 are docked, the push rod 201 will act on the truncated platform 13. As the docking proceeds, the push rod 201 will push the telescopic rod 12 toward the inner direction of the first connector 1 through the truncated platform 13, and the second cylindrical spring 14 will be 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 supporting 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.

[0042] 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 will slide close to each other on the guide beam 16, and the roller 19 will act 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.

[0043] 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 through groove 2601 on the inner wall. An airbag is arranged inside the fixing ring 26, and the airbag is connected to the air bag 28 arranged 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.

[0044] Please refer again Figure 8The locking mechanism includes a fixed arm 22 disposed on the outer wall of the first connector 1, two connecting posts 24 slidably disposed 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; 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.

[0045] When connecting the first connector 1 with the second connector 2, align the inclined portion 2301 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, so that the first connector 1 and the second connector 2 are connected. 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 through groove 2601, and the docking gap between the first connector 1 and the second connector 2 is shielded, which greatly improves the sealing 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.

[0046] 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: Step 1: Hold the first connector 1 and the second connector 2 and align and plug them together; Step 2: The elastic limiting mechanism is triggered, causing the elastic energy storage mechanism to release elastic potential energy, so that the first connecting terminal 3 moves along the circumference of the first connecting head 1 and contacts the second connecting terminal 4; 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 .
