Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and in particular to an electronic power steering connector that is easy to install and highly waterproof. Background Art

[0002] Electric power steering (EPS) is a power steering system that relies directly on an electric motor to provide auxiliary torque. Compared to the traditional hydraulic power steering (HPS) system, EPS has many advantages. EPS mainly consists of a torque sensor, vehicle speed sensor, electric motor, reduction gear, and electronic control unit (ECU). An electric power steering connector is required when connecting EPS.

[0003] Existing electronic power steering connectors often require bolts or other methods to secure the male and female connectors after they are plugged in to prevent them from loosening. This method of securing the connector is extremely inconvenient and takes a lot of time when the connector needs to be disassembled or replaced. Summary of the Invention

[0004] This invention discloses an electronic power steering connector that is easy to install and highly waterproof, aiming to solve the technical problem of inconvenient installation of existing electronic power steering connectors in the background art.

[0005] This invention proposes an electronic power steering connector that is easy to install and highly waterproof. It includes a female housing, with a male terminal slidably connected to the inner wall of the female housing. A base is provided on the inner wall of the male terminal away from the male terminal. Three equally spaced pins are provided on the inner wall of the male terminal away from the female housing, and all three pins are inserted into the base. Two symmetrical fixing seats are fixedly connected to the outside of the female housing, and two symmetrical fixing seats are fixedly connected to the outside of the male terminal. A mounting plate is fixedly connected to the side of each of the two fixing seats near the male terminal, and a connector is fixedly connected to the side of each of the two fixing seats near the female housing. A quick-release module is provided between the connector and the mounting plate on the same side. A water-proof module is provided outside the male terminal, located inside the female housing.

[0006] The device, comprising a female housing, connector, male terminal, mounting base one, mounting plate, quick-release module, waterproof module, mounting base two, pin, and base, utilizes the quick-release module to securely fix the male terminal to the female housing after it is inserted, ensuring a stable connection between the pin and the base. This effectively prevents the male terminal from detaching from the female housing, guaranteeing the functionality of the electronic power steering connector after installation and improving the convenience of installation and disassembly.

[0007] In a preferred embodiment, the quick-release module includes two symmetrical mounting cylinders. The upper sides of the two mounting cylinders are fixedly connected to the bottoms of two mounting plates, respectively. A beveled toothed seat is slidably connected inside each mounting cylinder. A spring is fixedly connected to the side of the beveled toothed seat opposite to the inner wall of the mounting cylinder on the same side. A transmission seat is slidably connected inside each mounting cylinder, located below the beveled toothed seat. A contact toothed ring is fixedly connected to the upper side of each transmission seat, and the teeth of the contact toothed ring contact the beveled surface of the beveled toothed seat. A limit ring is fixedly connected to the inner wall of each mounting cylinder. Three circumferentially equidistant stop plates are fixedly connected to the upper side of each limit ring. The outer surface of each transmission seat is open. The system includes three circumferentially equidistant strip grooves (I). Three stop plates located on the same mounting cylinder are slidably connected to the inner walls of the three strip grooves (I), with the ends of the stop plates away from the limiting rings engaging with the inclined surfaces of the teeth of the inclined gear seat. The outer surface of each inclined gear seat has three circumferentially equidistant strip grooves (II), staggered from the positions of the three strip grooves (I). The bottom of each transmission seat is fixedly connected to a contact rod. The outer surfaces of two contact rods are slidably connected to the inner walls of two limiting rings, with connecting parts located below the contact rods. The upper sides of the connecting parts are in contact with the bottom of the contact rods, and the outer surfaces of the connecting parts are slidably connected to the inner walls of the mounting cylinder. The outer surfaces of the connecting parts are also open... The mounting cylinder is equipped with an annular groove. Three circumferentially spaced rectangular grooves are formed on the exterior of each cylinder, and fastening rods are installed within each groove. Three circumferentially spaced supports are fixedly connected to the exterior of the mounting cylinder, and thin rods are fixedly connected to the supports. The exterior of each thin rod is movably connected to the end of the fastening rod furthest from the connecting member, while the end of the fastening rod closest to the connecting member is engaged with the inner wall of the annular groove. A torsion spring is installed on the exterior of each thin rod, with one end fixedly connected to the exterior of the thin rod and the other end fixedly connected to the end of the fastening rod furthest from the connecting member. Each fastening rod has a movable groove, within which a restraining rod is slidably connected. Three circumferentially spaced rectangular openings are formed on the exterior of each mounting cylinder. The ends of the restraining rods located on the same side near the rectangular opening are movably connected to the inner wall of the rectangular opening, and the ends of the restraining rods away from the rectangular opening are fixedly connected to two symmetrical short shafts; the outer sides of the short shafts are slidably connected to the side of the fastener rod away from the mounting cylinder; the three restraining rods located on the same mounting cylinder are all provided with the same constraint ring on their outer sides, the constraint ring is in contact with the opposite side of the restraining rod, the constraint ring is located between the fastener rod and the restraining rod, and the mounting cylinder is provided with three circumferentially equidistant openings, each of which is slidably connected to a connecting rod; the connecting rods located on the same mounting cylinder are all fixedly connected to the outer side of the constraint ring, and the connecting rods are all fixedly connected to the outer side of the transmission seat opposite to the outer side.

[0008] By incorporating a quick-release module, the fastener rod can be securely locked onto the rectangular slot using a constraint ring and restraint rod via a transmission seat in a locking position. This reduces the likelihood of the connector falling off due to vibration or collision during installation and use, ensuring connection stability and improving safety.

[0009] In a preferred embodiment, the water-proof module includes an annular groove formed on the inner wall of the mother shell. A water-blocking ring is slidably connected within the annular groove. The inner wall of the water-blocking ring is fixedly connected to the outside of the male terminal. A drainage groove is formed on the outside of the male terminal, located on the side of the water-blocking ring away from the mother shell. Two symmetrical receiving frames are fixedly connected to the side of the annular groove away from the water-blocking ring. Two symmetrical bosses are fixedly connected to the inner wall of each receiving frame. A bracket 1 is movably connected to the side of each boss away from the receiving frame. A bracket 2 is movably connected to the end of bracket 1 away from the boss. The ends of the two bracket 2s on the same side away from bracket 1 are movably connected to... The same supporting ring; the two supporting rings are fixedly connected to the same sealing ring one on the side away from the bracket two, and the water-blocking ring is fixedly connected to the sealing ring two on the side close to the supporting ring. The sealing ring two fits with the sealing ring one, and the two bosses on the same side are fixedly connected to the same shaft on opposite sides; the shaft is slidably connected to a movable part, and a push-pull rod is movably connected to each of the two movable parts. The end of the push-pull rod away from the movable part is movably connected to the outside of one of the brackets one on the same side, and the shaft is surrounded by a recoil spring. One end of the recoil spring is fixedly connected to the outside of one of the bosses, and the other end is fixedly connected to the outside of the movable part.

[0010] By incorporating a water-proof module, the water-proof module utilizes sealing ring one and sealing ring two to ensure a tight fit between sealing ring one and sealing ring two when the water-blocking ring applies pressure to the support ring, thanks to the thrust of the recoil spring. The slight deformation caused by the compression of sealing ring one and sealing ring two fills the gap between the female shell and the male terminal, thereby isolating the environment where the pins and base inside the female shell and male terminal are connected from the outside world. This prevents external moisture from entering, improves the waterproofness of the device, and avoids short circuits caused by moisture in the connector.

[0011] As can be seen from the above, the electronic power steering connector provided by the present invention is easy to install and has high waterproof performance. It can securely fix the male terminal to the female shell after the male terminal is inserted into the female shell, ensuring a stable connection between the pin and the base. This effectively avoids the male terminal from falling off the female shell, ensuring the functionality of the electronic power steering connector after installation and improving the convenience of installation and disassembly.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0015] The electronic power steering connector disclosed in this invention is easy to install and highly waterproof, and is mainly used in scenarios where the installation of existing electronic power steering connectors is inconvenient.

[0016] Reference Figure 1-7 An easy-to-install and highly waterproof electronic power steering connector includes a female housing 1. A male terminal 3 is slidably connected to the inner wall of the female housing 1. A base 10 is provided on the inner wall away from the male terminal 3. Three equally spaced pins 9 are provided on the inner wall away from the female housing 1, and all three pins 9 are inserted into the base 10. Two symmetrical fixing seats 1 4 are bolted to the outside of the female housing 1. Two symmetrical fixing seats 2 8 are bolted to the outside of the male terminal 3. Mounting plates 5 are bolted to the side of each of the two fixing seats 1 4 near the male terminal 3. Connecting parts 2 are bolted to the side of each of the two fixing parts 2 8 near the female housing 1. Quick-release modules 6 are provided between the connecting parts 2 and the mounting plates 5 on the same side. A water-proof module 7 is provided on the outside of the male terminal 3 and is located inside the female housing 1.

[0017] Specifically, when connecting the male terminal 3 to the female housing 1, align the male terminal 3 with the female housing 1 so that the pin 9 on the male terminal 3 is aligned with the base 10 on the female housing 1. Gently push the male terminal 3 into the female housing 1. During the insertion of the male terminal 3 into the female housing 1, the connector 2 connected to the fixing base 8 on the male terminal 3 will be inserted into the quick-release module 6. After the pin 9 is inserted into the base 10, the quick-release module 6 will lock the connector 2, thereby fixing the male terminal 3 in the female housing 1. If it is necessary to remove the male terminal 3 from the female housing 1, gently push the male terminal 3 again. The quick-release module 6 will then contact the female housing 1. The locking of connector 2 allows the male terminal 3 to detach from the female shell 1. After the male terminal 3 is inserted into the female shell 1, the water-proof module 7 seals the gap between the female shell 1 and the male terminal 3, preventing external water droplets or moisture from entering the female shell 1 and the male terminal 3. The device uses the quick-release module 6 to firmly fix the male terminal 3 to the female shell 1 after it is inserted into the female shell 1, ensuring a stable connection between the pin 9 and the base 10. This effectively prevents the male terminal 3 from falling off the female shell 1, ensuring the functionality of the electronic power steering connector after installation and improving the convenience of installation and disassembly.

[0018] Reference Figure 3 , Figure 4 and Figure 5In a preferred embodiment, the quick-release module 6 includes two symmetrical mounting cylinders 601. The upper sides of the two mounting cylinders 601 are respectively bolted to the bottom of the two mounting plates 5. A beveled toothed seat 603 is slidably connected inside each mounting cylinder 601. A spring 602 is bolted to the side of the beveled toothed seat 603 opposite to the inner wall of the mounting cylinder 601 on the same side. A transmission seat 604 is slidably connected inside each mounting cylinder 601. The transmission seats 604 are all located below the beveled toothed seats 603. A contact toothed ring 610 is bolted to the upper side of each transmission seat 604. The teeth of the contact toothed ring 610 contact the beveled surface of the teeth of the beveled toothed seat 603. The inner wall of each mounting cylinder 601 is connected to... A bolted connection is used to connect a limiting ring 607. Three circumferentially equidistant stop plates 606 are bolted to the upper side of each limiting ring 607. Three circumferentially equidistant strip grooves 605 are formed on the exterior of each transmission base 604. The exterior of the three stop plates 606, located on the same mounting cylinder 601, is slidably connected to the inner walls of the three strip grooves 605. The ends of the stop plates 606 furthest from the limiting ring 607 are engaged with the inclined surfaces of the teeth of the inclined gear seat 603. Three circumferentially equidistant strip grooves 609 are formed on the exterior of each inclined gear seat 603, and the positions of the three strip grooves 609 and the three strip grooves 605 are staggered. Contact rods 608 are bolted to the bottom of each transmission base 604. The outer surfaces of the contact rod 608 are slidably connected to the inner walls of the two limiting rings 607, and the connecting piece 2 is located below the contact rod 608. The upper side of the connecting piece 2 is in contact with the bottom of the contact rod 608, and the outer surfaces of the connecting pieces 2 are slidably connected to the inner wall of the mounting cylinder 601. The outer surfaces of the connecting pieces 2 are provided with annular grooves 611. The outer surfaces of the mounting cylinder 601 are provided with three circumferentially equidistant rectangular grooves 614. Each rectangular groove 614 is provided with a fastening rod 613. The outer surfaces of the mounting cylinder 601 are bolted to three circumferentially equidistant supports 612. Thin rods are bolted to the supports 612. The outer surfaces of the thin rods are rotatably connected to the end of the fastening rod 613 away from the connecting piece 2 through bearings. The end of 613 near the connector 2 is engaged with the inner wall of the annular groove 611. The outside of the thin rod is provided with a torsion spring 615. One end of the torsion spring 615 is connected to the outside of the thin rod by a bolt, and the other end is connected to the end of the fastener rod 613 away from the connector 2 by a bolt. The fastener rod 613 is provided with a movable groove 619. A restraining rod 617 is slidably connected in the movable groove 619. The outside of the mounting cylinder 601 is provided with three rectangular openings 616 that are equidistant from each other. The end of the restraining rod 617 on the same side near the rectangular opening 616 is rotatably connected to the inner wall of the rectangular opening 616 by a bearing. The end of the restraining rod 617 away from the rectangular opening 616 is connected to two symmetrical short shafts 618 by bolts.The outer surface of the short shaft 618 is slidably connected to the side of the fastener rod 613 away from the mounting cylinder 601. The outer surface of the three restraining rods 617 located on the same mounting cylinder 601 is provided with the same restraining ring 621. The restraining ring 621 fits against the opposite side of the restraining rod 617 and is located between the fastener rod 613 and the restraining rod 617. The mounting cylinder 601 has three circumferentially spaced openings, each with a slidably connected connecting rod 620. The connecting rods 620 located on the same mounting cylinder 601 are all bolted to the outer surface of the restraining ring 621. The connecting rods 620 are also bolted to the opposite side of the outer surface of the transmission seat 604.

[0019] Specifically, after the connector 2 is inserted into the mounting cylinder 601, the connector 2 pushes the transmission seat 604 connected to the contact rod 608 to move upward, so that the contact tooth ring 610 on the transmission seat 604 contacts the teeth of the oblique tooth seat 603 and pushes the oblique tooth seat 603 to move upward. At this time, the stop plate 606 is in a state of sliding in the first groove 605. When the oblique tooth seat 603 moves to the point where the stop plate 606 no longer slides in the second groove 609, the oblique tooth seat 603 rotates under the push of the teeth of the contact tooth ring 610 against the oblique surface of the teeth on the oblique tooth seat 603, so that the end of the stop plate 606 away from the limit ring 607 is... The bottom of the beveled surface of the beveled tooth seat 603 is engaged, preventing the beveled tooth seat 603 from rotating and stopping its movement within the mounting cylinder 601. As the beveled tooth seat 603 continues to move, the connecting rod 620 connected to the beveled tooth seat 603 drives the constraint ring 621 to move continuously toward the support 612. This causes the constraint ring 621 to press against the restraint rod 617 in the rectangular opening 616, causing the short shaft 618 sliding on the restraint rod 617 to press against the fastener rod 613 and retract it toward the mounting cylinder 601. Finally, one end of the fastener rod 613 penetrates into the rectangular groove 614 and engages the annular groove 611, thus fixing the connector 2 connected to the fixed seat 8 onto the mounting cylinder 601.

[0020] In specific application scenarios, the quick-release module 6 is mainly suitable for the quick-release stage in the quick-release process. That is, the quick-release module 6 uses the constraint ring 621 and the restraint rod 617 to securely lock the fastener rod 613 onto the rectangular groove 614 using the transmission seat 604 in the locking position. This reduces the occurrence of the connector 2 falling off due to factors such as vibration and collision during installation and use, ensures the stability of the connection, and improves safety.

[0021] Reference Figure 6 and Figure 7In a preferred embodiment, the water-proof module 7 includes an annular groove 701, which is formed on the inner wall of the mother shell 1. A water-blocking ring 703 is slidably connected within the annular groove 701. The inner wall of the water-blocking ring 703 is bolted to the outside of the male terminal 3. A drainage groove 704 is formed on the outside of the male terminal 3. The drainage groove 704 is located on the side of the water-blocking ring 703 away from the mother shell 1. Two symmetrical receiving frames 702 are bolted to the side of the annular groove 701 away from the water-blocking ring 703. Two symmetrical bosses 705 are bolted to the inner wall of each receiving frame 702. A bracket 706 is rotatably connected to the side of each boss 705 away from the receiving frame 702 via a bearing. A bracket 707 is rotatably connected to the end of each bracket 706 away from the boss 705 via a bearing. The ends of the two brackets 707 on the same side away from the bracket 706 are rotatably connected via bearings. There is a common support ring 708; the two support rings 708 are bolted to the side away from the bracket 707 and connected to the same sealing ring 709. The water-blocking ring 703 is bolted to the side of the support ring 708 and connected to the sealing ring 710. The sealing ring 710 fits with the sealing ring 709. The two bosses 705 on the same side are bolted to the opposite side and connected to the same shaft 711. The shaft 711 is slidably connected to the outside of each of the two shafts 712. Push-pull rods 714 are rotatably connected to each of the two shafts 712 through bearings. The end of the push-pull rod 714 away from the shaft 712 is rotatably connected to the outside of one of the brackets 706 on the same side through bearings. The shaft 711 is surrounded by a recoil spring 713. One end of the recoil spring 713 is bolted to the outside of one of the bosses 705 and the other end is bolted to the outside of the shaft 712.

[0022] Specifically, as the male terminal 3 is gradually inserted into the female housing 1, the sealing ring 710 on one side of the water-blocking ring 703 on the male terminal 3, after contacting and adhering to the sealing ring 709, will continue to push the supporting ring 708 connected to the sealing ring 709 towards the receiving frame 702. This causes the supporting ring 708 to press the bracket 707 and the bracket 706, reducing the angle between the bracket 707 and the bracket 706 and gradually folding them. The bracket 706, which is pushed and rotates towards the receiving frame 702, pushes the push-pull rod 714 connected to it to push the movable part 712 to slide on the shaft 711 against the thrust of the recoil spring 713, so that the water-blocking ring 703 can enter the annular groove 701 on the female housing 1. After the water from the outside falls onto the female housing 1 and the male terminal 3, it is collected and discharged through the drain groove 704. The water vapor is blocked by the sealing ring 709 and the sealing ring 710.

[0023] In specific application scenarios, the water-proof module 7 is mainly used in the water-proofing stage of the water-proofing process. That is, the water-proof module 7 uses sealing ring 1 709 and sealing ring 2 710 to make the water-blocking ring 703 press against the support ring 708, and the thrust of the recoil spring 713 makes the sealing ring 1 709 and sealing ring 2 710 fit tightly. The slight deformation caused by the compression of sealing ring 1 709 and sealing ring 2 710 fills the gap between the female shell 1 and the male terminal 3, thereby isolating the environment in which the pin 9 and the base 10 inside the female shell 1 and the male terminal 3 are connected from the outside world, ensuring that external moisture cannot enter, improving the waterproofness of the device, and avoiding the occurrence of short circuits due to moisture in the connector.

[0024] Working principle: When connecting the male terminal 3 to the female housing 1, align the male terminal 3 with the female housing 1 so that the pin 9 on the male terminal 3 can be aligned with the base 10 on the female housing 1. Gently push the male terminal 3 into the female housing 1. During the insertion of the male terminal 3 into the female housing 1, the connecting piece 2 pushes the transmission seat 604 connected to the contact rod 608 to move upward, so that the contact tooth ring 610 on the transmission seat 604 contacts the teeth of the oblique tooth seat 603 and pushes the oblique tooth seat 603 to move upward. At this time, the stop plate 606 is in a sliding state in the slot 605 and the oblique tooth When the seat 603 moves to the point where the stop plate 606 no longer slides in the second slot 609, the inclined gear seat 603 rotates under the push of the teeth of the contact ring 610 against the inclined surface of the teeth on the inclined gear seat 603. This causes the end of the stop plate 606 away from the limit ring 607 to engage with the bottom of the inclined surface of the teeth on the inclined gear seat 603, preventing the inclined gear seat 603 from rotating and stopping its movement in the mounting cylinder 601. During the continuous movement of the inclined gear seat 603, the connecting rod 620 connected to the inclined gear seat 603 drives the constraint ring 621 to move continuously toward the support 612, increasing the compressive torque of the constraint ring 621. The restraining rod 617 in the opening 616 causes the short shaft 618 sliding on the restraining rod 617 to press the fastening rod 613 towards the mounting cylinder 601. Finally, one end of the fastening rod 613 penetrates into the rectangular groove 614 and locks the annular groove 611, thus fixing the connector 2 connected to the fixing seat 8 onto the mounting cylinder 601. As the male terminal 3 is gradually inserted into the female shell 1, the sealing ring 710 on the side of the water-blocking ring 703 on the male terminal 3, after contacting and adhering to the sealing ring 709, will continue to push the support ring 708 connected to the sealing ring 709 towards the receiving frame 702. The support ring 708 presses against the second bracket 707 and the first bracket 706, reducing the angle between the second bracket 707 and the first bracket 706 and causing them to gradually fold. The first bracket 706, which is pushed and rotates towards the receiving frame 702, pushes the push-pull rod 714 connected to it, pushing the movable part 712 to slide on the shaft 711 against the thrust of the recoil spring 713, so that the water-blocking ring 703 can enter the annular groove 701 on the mother shell 1. After the water falls onto the mother shell 1 and the male terminal 3, it is collected and discharged through the drain groove 704, while the water vapor is blocked by the sealing ring 709 and the sealing ring 710.
