Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a cover actuator. Background Technology

[0002] Against the backdrop of the rapid development of the new energy vehicle industry and the deep integration of vehicle electrification and intelligence, the on-board charging system has become a core functional module of the vehicle. The automated control and reliable protection of the charging port cover are directly related to the vehicle's safety, ease of operation, and overall intelligence level. The SR port cover actuator, as the core drive and locking mechanism of the charging port cover, undertakes the key functions of automatic opening, smooth closing, precise positioning, and reliable locking of the charging port cover. It is a crucial foundational component for ensuring the safety of the charging interface and improving user experience. Its structural performance, operational stability, and environmental adaptability directly affect the reliability of the charging system and the service life of the entire vehicle.

[0003] Traditional charging port cover actuators have significant technical shortcomings: First, they are complex in structure and have redundant parts. Existing actuators generally adopt a combination of "motor + gear set + linkage mechanism", which includes more than ten kinds of parts such as worm gear, worm wheel, micro switch, and return spring. Not only is the assembly process cumbersome, requiring 8-10 steps to assemble a single actuator, but the cooperation of multiple parts is also prone to transmission gaps or jamming risks. For example, wear at the gear meshing and spring force decay can lead to actuator response delays or even failures where the cover cannot be opened or closed normally. According to industry statistics, failures caused by the complex structure of traditional actuators account for more than 40%.

[0004] Secondly, there is the contradiction between size and lightweight requirements. In order to accommodate multiple transmission components, the overall size of traditional actuators is usually large, while the charging port area in the cabin of new energy vehicles is compact, especially in small passenger cars. An oversized actuator will squeeze the layout of surrounding components and even limit the design of the charging port. At the same time, the use of multi-metal components also increases the weight of the actuator, which goes against the design trend of "lightweight and energy-saving" in new energy vehicles.

[0005] Thirdly, the actuator lacks precision in motion and reliability in sealing. Traditional actuators rely on the linkage of multiple components to achieve the positioning of the cover, but transmission errors can easily cause the cover to not fit completely against the vehicle body when closed, forming a gap of 0.5-1mm. This not only affects the overall appearance of the vehicle, but also allows rainwater and dust to enter the charging interface, accelerating the corrosion of the interface's metal components and even causing a short circuit risk. When the cover is open, if the actuator's stroke control precision is insufficient and the opening angle of the cover is too small, it will obstruct the plugging and unplugging of the charging gun, reducing the convenience of charging.

[0006] In addition, the disadvantages in cost and maintainability are also quite prominent: the procurement and assembly costs of multiple components of traditional actuators are high, and the entire unit needs to be disassembled and replaced after failure, which increases the time and economic cost of after-sales maintenance; at the same time, the complex structure has high requirements for the production process, and batch assembly errors are prone to occur, making it difficult to keep the product yield rate stable above 95%.

[0007] As competition intensifies in the new energy vehicle market, users' demands for charging experience are upgrading from "usability" to "convenience and reliability." Meanwhile, OEMs are also driving the transformation of components towards "integration, miniaturization, and low cost." The "New Energy Vehicle Industry Development Plan (2021-2035)" clearly states the need to improve the reliability and cost-effectiveness of core components, with optimization of charging system components being a crucial element. Against this backdrop, there is an urgent need for a charging port cover actuator that is structurally simple, compact, and reliable to address the aforementioned pain points of traditional products.

[0008] An ideal lid actuator should have the characteristics of "few parts, small size, and high precision": by simplifying the transmission structure to reduce the number of parts, thereby reducing assembly complexity and failure risk; by optimizing the spatial layout to achieve miniaturization and adapt to compact cabin space; and at the same time, by ensuring the accuracy of opening and closing actions to achieve tight sealing and smooth operation of the lid.

[0009] Therefore, we proposed a lid actuator to address the problems mentioned above. Summary of the Invention

[0010] The purpose of this invention is to provide a cap actuator to solve the problems mentioned in the background art, such as the complex structure and large size of the cap actuators for charging ports of new energy vehicles currently on the market.

[0011] To achieve the above objectives, the present invention provides the following technical solution: a lid actuator, comprising a housing, a lid, a bushing, and a worm gear nut. The lid is mounted on the housing, and the housing and the lid together form a closed cavity. Inside the housing and the lid, a motor, a worm, a worm nut, a rotating shaft, and a bushing are arranged. The output end of the motor is coaxially connected to the worm. The worm meshes with the worm nut for transmission. The worm nut is connected to the rotating shaft for transmission. The bushing is sleeved on the outside of the rotating shaft and fixedly connected to the housing.

[0012] Preferably, both the box body and the box cover adopt a PA66-GF30 structural design, and the surface of the box cover is composite injection molded with a TPS soft rubber layer.

[0013] The above structural design provides stable structural strength and high-temperature resistance. The TPS soft rubber layer on the surface of the cover can buffer external impacts and vibrations, reducing the impact of external forces on the internal motor, worm gear, worm nut, rotating shaft and bushing. The soft rubber layer is tightly bonded to the cover to form a flexible protective layer, preventing external dust and moisture from entering the closed cavity and maintaining the stable operation of the internal transmission structure.

[0014] Preferably, the soft rubber structure on the rotating shaft is injection molded and bonded to the hard rubber substrate as a single unit, and the soft rubber peel strength and oil resistance meet the requirements for vehicle use.

[0015] With the above structural design, the soft rubber structure rotates synchronously with the rotating shaft and buffers the frictional stress generated during rotation, reducing the rigid contact wear between the rotating shaft and the bushing. The soft rubber structure has stable oil resistance and peel strength, and does not fall off or deform during long-term rotation, providing continuous and stable flexible support and guidance for the rotating shaft.

[0016] Preferably, the rotating shaft is injection molded using a POM structure, and neodymium iron boron magnets are press-fitted onto the rotating shaft. The rotating shaft is partially covered with a TPC soft rubber structure.

[0017] The above structural design provides stable wear resistance and structural strength. The neodymium iron boron magnets pressed onto the rotating shaft can work with the external sensing structure to achieve position detection and positioning. The TPC soft rubber structure partially covering the rotating shaft further improves the smoothness of rotation and reduces the rotational resistance between the rotating shaft and the bushing, ensuring that the rotating shaft completes precise rotation and positioning under power drive.

[0018] Preferably, the bushing adopts a PA66-GF50 structural design, with the inner wall of the bushing and the rotating shaft having a clearance fit, providing radial support and rotational guidance for the rotating shaft.

[0019] The above structural design provides stable support strength and wear resistance. The inner wall of the bushing maintains a clearance fit with the rotating shaft, which does not restrict the normal rotation of the rotating shaft. At the same time, it provides uniform radial support and rotation guidance for the rotating shaft, constrains the rotational offset of the rotating shaft, avoids shaking and misalignment of the rotating shaft during rotation, and maintains the accuracy of the rotating shaft's rotation trajectory.

[0020] Preferably, the housing and the cover are connected by laser welding for sealing. The housing provides installation and positioning support for the motor, worm gear, worm nut and bushing, and the cover covers the top of the housing to achieve full enclosure protection.

[0021] With the above structural design, the welding interface fits tightly to form a complete sealed structure. The housing provides stable installation and positioning support for the internal motor, worm gear, worm nut and bushing, ensuring that the installation position of each component is accurate and the force is even. The cover completely covers the top of the housing to form a fully enclosed protection, preventing external dust, moisture and impurities from entering the cavity.

[0022] Preferably, the worm and the worm nut form a 90° reversing reduction transmission structure. The worm transmission has a self-locking function, and the rotation position of the rotating shaft is locked by the worm nut when the power is off.

[0023] By adopting the above structural design, the power output of the motor is reversed and reduced to match the rotation speed and transmission requirements of the rotating shaft. The worm has stable self-locking performance. When the motor is powered off and stops outputting power, the worm locks the rotation position of the worm nut through the meshing structure with the worm nut, thereby locking the rotation position of the rotating shaft and preventing accidental rotation and displacement of the rotating shaft.

[0024] Preferably, the motor is a forward and reverse speed-regulating drive mechanism, in which the motor drives the worm gear to rotate forward or in reverse, thereby driving the worm nut and the rotating shaft to complete the opening, closing and locking actions of the charging port cover.

[0025] With the above structural design, when the motor rotates forward, it drives the worm gear to rotate synchronously. The worm gear drives the worm nut to rotate and drives the rotating shaft to complete the opening action of the charging port cover. When the motor rotates in reverse, it drives the worm gear to rotate synchronously in reverse. The worm gear drives the worm nut to rotate in reverse and drives the rotating shaft to complete the closing and locking action of the charging port cover, realizing the automatic opening, closing and locking control of the charging port cover.

[0026] Preferably, the rotating shaft, worm gear, and worm nut are all designed with a POM structure, and the worm nut and rotating shaft rotate synchronously through a transmission structure.

[0027] The above structural design results in uniform structural performance and high transmission matching. When the worm rotates, it maintains stable meshing with the worm nut. The worm nut and the rotating shaft achieve synchronous rotation through the transmission structure. The power transmission process is smooth and without jamming, reducing friction loss and transmission error between components and maintaining the stable operation of the overall transmission structure.

[0028] Preferably, the actuator has passed tests for high temperature resistance, low temperature resistance, low temperature alternation, damp heat cycling, chemical media resistance, vibration, free fall, salt spray, soft rubber peel force, and soft rubber oil resistance, making it suitable for use in complex vehicle environments.

[0029] With the above structural design, the overall actuator, through long-term use, forms a stable transmission system with the cooperation of the housing, cover, rotating shaft, bushing, motor, worm gear and worm nut. It can withstand high and low temperature changes, humid heat cycles, chemical media corrosion, vibration and drop impact in the vehicle environment. The performance of each component is stable and there will be no deformation, damage or failure. It continuously provides stable drive and locking support for the charging port cover.

[0030] Compared with the prior art, the beneficial effects of the present invention are: the cap actuator: 1. Compact and lightweight, suitable for installation in confined spaces. The overall structure is highly integrated, with a compact size for the box and cover. The lightweight support design of the bushing further reduces the volume and weight, perfectly adapting to the narrow layout space of the charging port of new energy vehicles. At the same time, it reduces the overall vehicle load and energy consumption, which is in line with the design trend of miniaturization and lightweighting of vehicle components and is compatible with multi-model platform use. 2. The structure is simplified and reliable, significantly reducing the number of potential failure points. The lid actuator achieves its core functions through only the housing, lid, rotating shaft, bushing, motor, worm gear and worm nut. It eliminates the traditional redundant connecting rod and spring structure, reduces transmission links, reduces the probability of failures such as jamming and loosening from the root, simplifies the assembly process, and improves production yield and long-term use stability. 3. Comprehensive sealing and protection, adaptable to harsh vehicle environments. The enclosure and lid are sealed by laser welding to form a complete closed cavity, effectively preventing rainwater, dust and chemical media from entering the interior. Combined with the high weather resistance of PA66-GF30 material, it can stably pass the harsh vehicle tests such as high and low temperature, damp heat, salt spray and vibration, protecting precision components such as motor, worm gear and worm nut from external environmental corrosion. 4. Precise and efficient transmission, with rapid and delay-free action response. The motor directly drives the worm gear and worm nut to form a 90° reversing reduction transmission. The power transmission path is short and the loss is small. The rotating shaft achieves wobbly rotation under the precise guidance of the bushing. This ensures that the opening, closing and locking actions of the charging port cover are completed in one go, without gaps or offset, which significantly improves the actuator response speed and control accuracy. 5. Excellent self-locking performance, ensuring more reliable safety locking during power outages. The transmission structure composed of the worm gear and worm nut has a natural self-locking characteristic. After the motor is powered off, the position of the rotating shaft can be locked immediately to prevent the charging port cover from accidentally shaking or opening and closing on its own. Combined with the high wear resistance of POM material, it can maintain a stable locking force even after long-term use, ensuring that the charging port cover is always in a safe and fixed state while the vehicle is in motion.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-8This invention provides a technical solution: a lid actuator, comprising a housing 1, a lid 2, a rotating shaft 3, a bushing 4, a motor 5, a worm gear 6, and a worm nut 7. The lid 2 is mounted on the housing 1. Both the housing 1 and the lid 2 adopt a PA66-GF30 structural design. The surface of the lid 2 is composite-injected with a TPS soft rubber layer, which has stable structural strength and high temperature resistance. The composite-injected TPS soft rubber layer on the surface of the lid 2 can buffer external impacts and vibrations, reducing the impact of external forces on the internal motor 5, worm gear 6, worm nut 7, rotating shaft 3, and bushing 4. The soft rubber layer is tightly bonded to the lid 2 to form a flexible protective layer, preventing external dust and moisture from entering the enclosed cavity and maintaining the stable operation of the internal transmission structure. The housing 1 and the lid 2 together form a closed cavity. The motor 5, worm gear 6, worm nut 7, rotating shaft 3, and bushing 4 are arranged inside the housing 1 and the lid 2. The soft rubber structure on the rotating shaft 3 is bonded to the hard rubber substrate. The soft rubber structure is injection molded into one piece, and its peel strength and oil resistance meet the requirements for automotive use. The soft rubber structure rotates synchronously with the rotating shaft 3 and buffers the frictional stress generated during rotation, reducing the rigid contact wear between the rotating shaft 3 and the bushing 4. The soft rubber structure has stable oil resistance and peel strength, and will not detach or deform during long-term rotation, providing continuous and stable flexible support and guidance for the rotating shaft 3. The rotating shaft 3 is injection molded using a POM structure, and neodymium iron boron magnets are press-fitted onto the rotating shaft 3. The rotating shaft 3 is partially covered with a TPC soft rubber structure, which has stable wear resistance and structural strength. The neodymium iron boron magnets press-fitted onto the rotating shaft 3 can work with external sensing structures to achieve position detection and positioning. The partially covered TPC soft rubber structure of the rotating shaft 3 further improves the smoothness of rotation and reduces the rotational resistance between the rotating shaft 3 and the bushing 4, ensuring that the rotating shaft 3 completes precise rotation and positioning under power drive.

[0035] The bushing 4 adopts a PA66-GF50 structure design. The inner wall of the bushing 4 is clearance-fitted with the rotating shaft 3, providing radial support and rotational guidance for the rotating shaft 3. It has stable support strength and wear resistance. The clearance fit between the inner wall of the bushing 4 and the rotating shaft 3 does not restrict the normal rotation of the rotating shaft 3, while providing uniform radial support and rotational guidance, constraining the rotational offset of the rotating shaft 3, and preventing wobbling and misalignment during rotation, thus maintaining the accuracy of the rotation trajectory of the rotating shaft 3. The output end of the motor 5 is coaxially connected to the worm gear 6. The worm gear 6 meshes with the worm nut 7 for transmission. The worm nut 7 and... The rotating shaft 3 is connected to the drive, and the bushing 4 is fitted on the outside of the rotating shaft 3 and fixedly connected to the housing 1. The housing 1 and the cover 2 are connected by laser welding. The housing 1 provides installation and positioning support for the motor 5, worm gear 6, worm nut 7 and bushing 4. The cover 2 covers the top of the housing 1 to achieve full enclosure protection. The welded interface fits tightly to form a complete sealing structure. The housing 1 provides stable installation and positioning support for the internal motor 5, worm gear 6, worm nut 7 and bushing 4, ensuring that the installation position of each component is accurate and the force is even. The cover 2 completely covers the top of the housing 1 to form full enclosure protection, preventing external dust, moisture and impurities from entering the cavity.

[0036] The worm gear 6 and worm nut 7 form a 90° reversing reduction transmission structure. The worm gear 6 transmission has a self-locking function. When power is off, it locks the rotational position of the rotating shaft 3 through the worm nut 7, thus reversing and reducing the power output from the motor 5 to match the rotational speed and transmission requirements of the rotating shaft 3. The worm gear 6 has a stable self-locking performance. When the motor 5 stops outputting power, the worm gear 6 locks the rotational position of the worm nut 7 through its meshing structure, thereby locking the rotational position of the rotating shaft 3 and preventing accidental rotation of the rotating shaft 3. The displacement phenomenon is addressed by using a forward and reverse speed-regulating drive mechanism, where motor 5 drives worm gear 6 to rotate forward or backward, thereby driving worm nut 7 and rotating shaft 3 to open, close, and lock the charging port cover. When motor 5 rotates forward, it drives worm gear 6 to rotate synchronously forward, which in turn drives worm nut 7 to rotate and drive rotating shaft 3 to open the charging port cover. When motor 5 rotates in reverse, it drives worm gear 6 to rotate synchronously in reverse, which in turn drives worm nut 7 to rotate in the opposite direction and drive rotating shaft 3 to close and lock the charging port cover, thus achieving automated opening, closing, and locking of the charging port cover. The control system, including the rotating shaft 3, worm gear 6, and worm nut 7, all adopts a POM structure design. The worm nut 7 rotates synchronously with the rotating shaft 3 through a transmission structure, resulting in uniform structural performance and high transmission matching. When the worm gear 6 rotates, it maintains stable meshing with the worm nut 7. The worm nut 7 and the rotating shaft 3 achieve synchronous rotation through the transmission structure, ensuring smooth and uninterrupted power transmission. This reduces frictional losses and transmission errors between components, maintaining the stable operation of the overall transmission structure. The actuator has passed tests for high temperature resistance, low temperature resistance, low temperature alternation, damp heat cycling, chemical media resistance, vibration, free fall, salt spray, soft rubber peeling force, and soft rubber oil resistance, making it suitable for use in complex vehicle environments. During long-term use, the actuator, with its housing 1, cover 2, rotating shaft 3, bushing 4, motor 5, worm gear 6, and worm nut 7 working together to form a stable transmission system, can withstand high and low temperature changes, damp heat cycling, chemical media corrosion, vibration, and drop impacts in the vehicle environment. The performance of each component remains stable without deformation, damage, or failure, continuously providing stable drive and locking support for the charging port cover.

[0037] Working principle: When using this cover actuator, firstly, the motor 5 starts to run after receiving the control signal. The output end of the motor 5 directly drives the worm 6 to rotate coaxially. The worm 6 and the worm nut 7 maintain a meshing state and transmit power to the worm nut 7. The worm nut 7 transmits the received power synchronously to the rotating shaft 3, so that the rotating shaft 3 and the worm nut 7 rotate synchronously in the same direction.

[0038] The bushing 4 is fitted on the outside of the rotating shaft 3 and is fixedly connected to the housing 1. The bushing 4 provides stable radial support and precise rotation guidance for the rotating shaft 3, constraining the rotation trajectory of the rotating shaft 3 to avoid shaking and deviation. The housing 1 and the cover 2 are laser welded to form a closed cavity. The housing 1 provides stable installation and positioning support for the motor 5, worm gear 6, worm nut 7, rotating shaft 3 and bushing 4. The cover 2 covers the top of the housing 1 to achieve full enclosure protection, preventing external dust, water vapor, chemical media and impurities from entering the interior and affecting the transmission.

[0039] During rotation, the rotating shaft 3 drives the vehicle charging port cover to complete the corresponding opening, closing, or locking actions. The transmission structure formed by the worm gear 6 and the worm nut 7 maintains a natural self-locking state. When the motor 5 is de-energized and stops running, the worm gear 6 directly locks the rotational position of the worm nut 7 through its meshing structure. The worm nut 7 synchronously locks the rotational position of the rotating shaft 3, keeping the charging port cover fixed and preventing accidental shaking or displacement. The rotating shaft 3, worm gear 6, and worm nut 7 maintain stable transmission. The housing 1, housing cover 2, rotating shaft 3, bushing 4, motor 5, worm gear 6, and worm nut 7 cooperate to form a complete transmission system, continuously and stably completing the automated opening, closing, and locking of the charging port cover, thus completing a series of tasks. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
