The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0027] As attached Figure 1-9 The illustrated charging door actuator assembly includes: a housing 1 for assembling an actuator mechanism and an electric unlocking component; an actuator mechanism including a drive rod 2, a return spring 3, and a locking component; the drive rod is movably disposed within a mounting cavity 1.11, with its upper end extending out of the housing; the return spring 3 pushes the drive rod upward; the locking component locks or unlocks the drive rod, and the up-and-down movement of the drive rod 2 drives the locking component to operate; and an electric unlocking component 5 including a motor 5.1 and a positioning pin 5.2; the motor 5.1 drives the positioning pin 5.2 to extend and retract; a locking hole 2.1 is provided at the bottom of the drive rod, and when the drive rod is in the locked state, the positioning pin 5.2 can extend movably into the locking hole 2.1. The actuator mechanism enables the charging door to be locked by pressing and opened by pressing again. The electric unlocking component further improves reliability and prevents accidental unlocking; that is, after locking, the drive rod is only unlocked after the electric unlocking component is unlocked. The structure is simple, assembly is convenient and efficient, and its small size makes it easy to assemble into a car.
[0028] Based on the above, the mounting cavity 1.11 has multiple positioning plates 1.12 on its sidewalls, with a sliding groove 1.13 formed between adjacent positioning plates 1.12. A positioning groove 1.14 is provided at the bottom of each positioning plate 1.12. A positioning post 1.15 is also provided inside the mounting cavity 1.11. The locking assembly includes a limiting ring, which is movably fitted onto the bottom of the drive rod. Multiple limiting plates 4.1 are provided inside the limiting ring, with a limiting opening 4.2 between two limiting plates 4.1. A groove 1.1 is provided on the outside of the limiting ring. The drive rod 2 has a corresponding limiting block 4.3, a positioning block 2.2 corresponding to the limiting port 4.2, and a threaded groove 2.3 that mates with the positioning post 1.15 on the outer side of the drive rod. A vertical groove 2.4 is located at the upper end of the threaded groove 2.3. The housing also has an annular drive tooth 1.4 located below the positioning plate 1.12. A return spring 3 is located inside the housing and abuts against the drive rod. The actuator allows for a press-to-lock and press-again-unlock function, facilitating user operation. The vertical groove 2.4 allows the positioning block 2.2 to move vertically downwards from the limiting port 4.2 when the drive rod initially moves downwards.
[0029] Specifically, a connecting rod 2.6 is coaxially provided at the lower end of the aforementioned drive rod 2. The outer diameter of the connecting rod 2.6 is smaller than that of the drive rod. The limiting ring is movably sleeved on the outside of the connecting rod 2.6. The positioning block 2.2 is fixed to the connecting rod 2.6. The limiting plate 4.1 is provided between the positioning block 2.2 and the drive rod. The connecting rod 2.6 ensures the reliability of pressing the limiting ring when the drive rod moves downward.
[0030] Based on the above, the housing includes a detachable upper housing 1.1 and a lower cover 1.2. The mounting cavity 1.11 is located inside the upper housing 1.1, the drive gear 1.4 is located in the lower housing, the lower housing is provided with a fixing post 1.21, the drive rod is provided with a fixing hole 2.5 in the middle, and the return spring 3 is sleeved on the outside of the fixing post 1.21. The return spring 3 is embedded in the fixing hole 2.5 and abuts against the drive rod. The detachable upper housing 1.1 and lower cover 1.2 can effectively improve the assembly efficiency of the actuator assembly and increase the production speed. At the same time, sleeved on the outside of the fixing post 1.21, the return spring 3 can ensure the reliability of the return spring 3 and prevent the return spring 3 from shaking or shifting.
[0031] To further explain, the lower housing is provided with a fixed sleeve 1.22, and the drive tooth 1.4 is located inside the fixed sleeve 1.22. When the lower end of the drive rod 2 moves downward, it can penetrate into the fixed sleeve 1.22. The fixed sleeve 1.22 has a movable hole 1.23. The lower housing is also provided with a guide groove 1.24. The positioning pin 5.2 is laterally slidably located in the guide groove 1.24 and can extend from the movable hole 1.23 into the locking hole 2.1. The fixed sleeve 1.22 facilitates the processing and forming of the drive tooth 1.4 and improves the stability of the drive tooth 1.4. The guide groove 1.24 ensures the stability of the lateral movement of the positioning pin 5.2.
[0032] The aforementioned positioning pin 5.2 is also provided with an auxiliary strip 5.21 along its length. The lower housing is provided with multiple support columns 1.26, and the support columns 1.26 are provided with auxiliary grooves 1.27 that cooperate with the auxiliary strip 5.21. The auxiliary strip 5.21 and the auxiliary grooves 1.27 can further improve the stability of the positioning pin 5.2 during lateral movement, ensuring that the motor 5.1 drives it accurately and stably. Preferably, in order to further ensure the movement accuracy of the positioning pin 5.2, the positioning pin 5.2 is provided with a limiting ridge 5.22, and the fixing sleeve 1.22 is provided with a blocking part 1.25 corresponding to the limiting ridge 5.22. The cooperation between the limiting ridge 5.22 and the blocking part 1.25 can limit the movement stroke of the positioning pin 5.2 and prevent it from excessive lateral movement.
[0033] It is worth mentioning that the upper housing 1.1 is also provided with an assembly position 1.3. The motor 5.1 is fixedly embedded in the assembly position 1.3. The output shaft of the motor 5.1 is provided with a drive wheel. The positioning pin 5.2 meshes with the drive wheel. The assembly position 1.3 facilitates the assembly of the motor 5.1. That is, the motor 5.1 can be fixedly embedded by inserting it into the assembly position 1.3, thereby improving the assembly efficiency.
[0034] The housing of this utility model is also provided with a sealing ring 6 that seals with the drive rod. The sealing ring 6 can reduce the entry of debris and dust into the housing, thereby extending the service life of the electric door actuator assembly.
[0035] The specific working process of this utility model is as follows: Pressing the drive rod 2 causes it to move downwards. With the cooperation of the threaded groove 2.3 and the positioning pin 1.15, the drive rod 2 rotates simultaneously during its downward movement. Simultaneously, as the drive rod moves downwards, it drives the limiting ring 4 to move downwards along the sliding groove 1.13. Due to the cooperation between the limiting block 4.3 and the sliding groove 1.13, the limiting ring can only move vertically along the sliding groove 1.13. At the same time, the positioning block 2.2 on the drive rod 2 moves downwards from the limiting opening 4.2 and disengages. When the drive rod continues to move downwards, it drives the limiting ring 4 to move downwards and disengage from the sliding groove 1.13. If the downward pressure continues, the limiting block 4.3 on the limiting ring cooperates with the drive tooth 1.4, forcing the limiting ring to rotate and deflect. At this time, the limiting block 4.3 is aligned with the positioning groove 1.14, and the positioning block 2.2 is located below the limiting plate 4.1. After the downward pressure on the drive rod is removed, the drive rod moves upward under the action of the return spring 3. At this time, the positioning block 2.2 moves upward with the drive rod 2, and drives the limit ring to move upward synchronously, driving the limit block 4.3 into the positioning groove 1.14. The limit block 4.3, which has entered the positioning groove 1.14, is restricted from moving upward. At the same time, the limit plate 4.1 blocks the upward movement of the positioning block 2.2, thereby achieving locking. When the drive rod is in the locked state, the locking hole 2.1 of the drive rod is aligned with the positioning pin 5.2. The positioning pin 5.2 is driven to move laterally by the motor 5.1 to achieve electric locking, thereby ensuring the reliability of locking. When unlocking is required, the positioning pin 5.2 is first driven laterally by the motor 5.1 to unlock, that is, the positioning pin 5.2 is moved out of the locking hole 2.1. Then, press the drive rod to move it downwards, causing the limiting ring 4 to move downwards simultaneously. At this time, the limiting block 4.3 on the limiting ring cooperates with the drive tooth 1.4 to force the limiting ring to rotate and shift again. At this time, the limiting block 4.3 is aligned with the sliding groove 1.13. Remove the downward pressure of the drive rod, and the drive rod is pushed upwards by the return spring 3. The drive rod drives the limiting ring to move upwards along the sliding groove 1.13. At the same time, the drive rod rotates in the opposite direction to reset while moving upwards with the cooperation of the positioning block 2.2 and the spiral groove, thus unlocking.
[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
