[0024] This application discloses a manual unlocking structure for use in a cover actuator, suitable for use in a vehicle, for controlling the locking or unlocking of the cover.

[0025] Please see Figures 1-4 As shown, the manual unlocking structure includes a housing 1, a locking rod 2, a slip ring 3, a spring 4, a locking tongue 5, a driving component 6, a transmission disc 7, and a lever 8.

[0026] In this embodiment, the manual unlocking structure is set vertically, and the axis of the locking rod 2 is in the vertical direction.

[0027] After the lower end of the locking rod 2 rotates through the connecting hole on the housing 1, it is positioned inside the housing 1 via a spring 4. A groove 201 and a slot 202 are formed on the peripheral wall of the locking rod 2. A slip ring 3 is fitted onto the locking rod 2 and rotatably mounted inside the housing 1. A slider 301 is provided on the inner ring of the slip ring 3. The slider 301 is adapted to cooperate with the groove 201 to restrict the rotation of the locking rod 2. This, in turn, controls the locking or unlocking of the cover by the pressure tongue 208 at the upper end of the locking rod 2.

[0028] The latch 5 is horizontally positioned and slidably disposed within the housing 1. A drive unit 6 is mounted within the housing 1. The drive unit 6 is adapted to drive the latch 5 into or out of the slot 202 via a transmission disc 7. A lever 8 is located on the side of the transmission disc 7 away from the latch 5. The lever 8 is rotatably disposed within the housing 1 via a torsion spring 9. A lever block 801 is provided at one end of the lever 8 near the transmission disc 7 (i.e., the upper end of the lever 8), while the other end of the lever 8 (i.e., the lower end of the lever 8) is exposed outside the housing 1 and adapted to connect a pull cord.

[0029] When the pull rope is in a free state, the lever 801 separates from the notch 701 of the transmission disc 7 under the action of the torsion spring 9. When the pull rope is in a pulled state, the lever 801 moves the transmission disc 7 through the notch 701 to drive the locking tongue 5 out of the slot 202.

[0030] The use of slider 301 in conjunction with slide groove 201 to restrict the rotation of locking rod 2 is existing technology and will not be described in detail.

[0031] In this embodiment, the locking lever 2, the transmission disc 7, and the lever 8 are aligned axially. The sliding direction of the locking tongue 5 is perpendicular to the axial direction of the locking lever 2.

[0032] Please see Figure 1 As shown, housing 1 includes an upper cover 101 and a lower cover 102. The upper cover 101 is disposed on top of the lower cover 102. A connector 106 is provided on the outer wall of the lower cover 102. The connector 106 is adapted to be connected to the vehicle. A connecting protrusion 103 is provided on the inner side of the upper cover 101. The connecting protrusion 103 is rotatably connected to the center hole on the end face of the lever 8. The peripheral wall of the lever 8 is rotatably connected to the inner cavity of the lower cover 102. The top surface and bottom surface of the lever 8 abut against the inner wall of the upper cover 101 and the outer wall of the insertion interface of the lower cover 102, respectively.

[0033] After the lower end of the locking rod 2 rotates through the connecting hole on the upper cover 101, it is positioned inside the lower shell 102 via a spring 4. A double-layer sealing soft rubber ring 104 is provided between the locking rod 2 and the upper cover 101; the inner ring of the double-layer sealing soft rubber ring 104 has a first layer of seal, a second layer of seal, and a groove structure between the first layer of seal and the second layer of seal. The first layer of seal and the second layer of seal are respectively press-fitted to the peripheral wall of the locking rod 2. The first layer of seal can block most of the dust, moisture, and foreign objects from the outside of the shell 1, and in addition to its protective function, it also has the function of cleaning the peripheral wall of the locking rod 2. The groove structure can make the first layer of seal and the second layer of seal more elastic. The double-layer sealing structure can effectively prevent water and dust, thereby improving the service life of the manual unlocking mechanism.

[0034] The slip ring 3 is rotatably disposed inside the lower shell 102. The top and bottom surfaces of the slip ring 3 abut against the lower end surface of the upper cover 101 and the stepped surface of the lower shell 102, respectively.

[0035] Spring 4 is sleeved on the vertical rod 105 inside the lower housing 102. The axial direction of the vertical rod 105 is consistent with the axial direction of the locking rod 2. The lower end of spring 4 abuts against the inner bottom wall of the lower housing 102. The upper end of spring 4 is placed in the axial center hole at the bottom of the locking rod 2 and abuts against the locking rod 2.

[0036] The transmission disc 7, locking tongue 5, and driving member 6 are arranged sequentially from top to bottom (i.e., along the axial direction of the locking rod 2) within the lower housing 102. The transmission disc 7 is rotatably mounted on and within the lower housing 102. The locking tongue 5 is slidably connected to a slot 107 on the lower housing 102. The driving member 6 is installed within the lower housing 102, and its driving end is adapted to drive the transmission disc 7 to rotate. In this embodiment, the driving member 6 includes a motor and a controller connected to the motor.

[0037] For further details, please refer to Figure 5 and Figure 6As shown, the transmission disc 7 is provided with a mating groove 702. The locking tongue 5 is rotatably and slidably connected to the mating groove 702 via a connecting post 501. The axial direction of the connecting post 501 is consistent with the axial direction of the locking rod 2. In this embodiment, the mating groove 702 is an elongated hole.

[0038] Furthermore, the transmission disc 7 has a mating groove 702 and a toothed groove 703 on the side near the drive member 6. The output end of the drive member 6 meshes with the toothed groove 703 through a gear 10. The output end of the drive member 6 drives the transmission disc 7 to rotate through the engagement of the gear 10 and the toothed groove 703, and the transmission disc 7 moves through the engagement of the connecting column 501 with the mating groove 702.

[0039] In this embodiment, to save space, the transmission disc 7 includes a main shaft 704, a semicircular portion 705, and a protrusion 706. The main shaft 704 is rotatably mounted on the lower housing 102. The semicircular portion 705 is disposed on the peripheral wall of the main shaft 704 and is located on the side of the main shaft 704 closer to the latch 5. The protrusion 706 is disposed on the peripheral wall of the main shaft 704 and is located on the side of the main shaft 704 away from the latch 5. The protrusion 706 and the semicircular portion 705 form a notch 701. A mating groove 702 and a toothed groove 703 are both disposed on the semicircular portion 705, and the toothed groove 703 is a fan-shaped toothed groove. The lever 801 is adapted to actuate the protrusion 706, so that the transmission disc 7 drives the latch 5 to move.

[0040] Please see Figures 1-2 As shown, the lever 8 includes a lever block 801, a lever body 802, and a rope cantilever 803. The lever body 802 is rotatably mounted inside the lower housing 102. The lever body 802 has the lever block 801 at one end near the transmission disc 7 (i.e., the upper end of the lever body 802), and the other end (i.e., the lower end of the lever body 802) is exposed outside the lower housing 102 and has the rope cantilever 803. The rope cantilever 803 has a connection hole for connecting a pull rope. A torsion spring 9 and a waterproof ring 804 are provided between the lever body 802 and the lower housing 102. The torsion spring 9 is located between the lever block 801 and the rope cantilever 803. The waterproof ring 804 is located between the torsion spring 9 and the rope cantilever 803 for effective waterproofing and dustproofing. The rope cantilever 803 is located outside the lower housing 102 and is suitable for connecting a pull rope.

[0041] Furthermore, for better protection of slip ring 3, please refer to... Figure 7 and Figure 8 As shown, the inner wall of the housing 1 is provided with a guide block 108, and the peripheral wall of the locking rod 2 is correspondingly provided with a spiral groove 203. The guide block 108 and the spiral groove 203 are slidably engaged. The spiral groove 203 includes a vertically arranged limiting section and a spiral section provided at the end of the limiting section.

[0042] In this embodiment, the slide 201 is a circulation groove, including multiple V-shaped grooves. Specifically, the multiple V-shaped grooves are distributed at equal angles around the locking rod 2, and the multiple V-shaped grooves are connected sequentially to form the circulation groove. Please refer to [link to documentation]. Figure 2 and Figure 8 As shown, the V-shaped groove has a starting end, a lower corner, and an ending end. An upper limit groove 204 and a lower limit groove 205 are respectively formed on the two side walls of the starting end of the V-shaped groove. A transition groove 206 is provided at the ending end of the V-shaped groove. An unlocking groove 207 is provided at the lower corner of the V-shaped groove. The slider 301 is adapted to slide cyclically in a clockwise direction within the circulation groove.

[0043] In this embodiment, the manual unlocking structure works as follows: When the manual unlocking mechanism is in the locked state, the long side of the latch 208 is perpendicular to the long side of the keyhole 11 (e.g., Figure 12 As shown), that is, the locking hole 11 on the locking cap of the latch 208; at this time, the latch 5 is inserted into the slot 202, the guide block 108 is placed at the end of the limiting section, and the slider 301 is placed in the lower limiting groove 205 (as shown). Figure 9 (As shown).

[0044] When the driving component 6 drives the locking tongue 5 to disengage from the slot 202, the locking rod 2, the slider 301, and the guide block 108 move relative to each other under the action of the spring 4. The upper end of the locking rod 2 moves axially away from the housing 1. Specifically, the slider 301 slides from the lower limiting groove 205 to the upper limiting groove 204, while the guide block 108 slides from the end of the limiting section to the beginning of the limiting section (e.g., ...). Figure 9 and Figure 10 (As shown); slider 301 then slides from the upper limit slot 204 to the unlocking slot 207, while guide block 108 slides from the beginning of the limiting segment to the end of the spiral segment (as shown). Figure 8 (As shown). When the guide block 108 engages with the spiral section, the locking rod 2 rotates, causing the pressure tongue 208 to rotate, thereby aligning the long side of the pressure tongue 208 with the long side of the lock hole 11.

[0045] When the manual unlocking mechanism is in the free state, the long side of the latch 208 is aligned with the long side of the keyhole 11 (e.g., Figure 11 As shown), the cover can be separated from the pressure tongue 208; at this time, the locking tongue 5 disengages from the slot 202, the guide block 108 is placed at the end of the spiral section, and the slider 301 is placed in the unlocking slot 207. At this time, the operator can pull out the cover to separate the lock hole 11 from the pressure tongue 208.

[0046] During the process of switching the manual unlocking mechanism from the free state to the locked state, the operator presses the cap down onto the pressure tongue 208 to insert it into the lock hole 11. At this time, the pressure tongue 208 is indirectly pressed down by the operator, causing the upper end of the locking rod 2 to move axially towards the housing 1. Simultaneously, the slider 301 slides from the unlocking groove 207 to the transition groove 206, while the guide block 108 slides from the end of the spiral section to the limiting section. Guided by the transition groove 206 and the action of the spring 4, the slider 301 then slides from the transition groove 206 to the lower limiting groove 205 at the beginning of the adjacent V-shaped groove, while the guide block 108 is positioned at the end of the limiting section. Afterwards, the drive unit 6 drives the locking tongue 5 to insert into the slot 202. When the guide block 108 engages with the spiral section, the locking rod 2 rotates, causing the pressure tongue 208 to rotate, thus making the long side of the pressure tongue 208 perpendicular to the long side of the lock hole 11, i.e., the manual unlocking mechanism is in the locked state.

[0047] During the above process, the toggle block 801 separates from the notch 701 of the transmission disc 7 under the action of the torsion spring 9, meaning that the toggle block 801 will not interfere with the rotation of the transmission disc 7. When the manual unlocking device requires manual pulling of the pull rope for emergency use, pulling the pull rope causes the toggle block 801 to rotate via the lever 8. The toggle block 801 then moves the transmission disc 7, which in turn moves the locking tongue 5 to disengage it from the slot 202. In this embodiment, the driving component 6 is a standard motor without a brake. When the standard motor without a brake is not powered, its output shaft (i.e., the output end of the driving component 6) can be manually rotated. When the toggle block 801 moves the transmission disc 7, the transmission disc 7 can drive the output shaft of the motor to rotate via the gear 10, meaning that at this time, the driving component 6 will not interfere with the transmission disc 7.

[0048] In summary, the manual unlocking structure provided in this application, through the cooperation of the latch, transmission disc, lever, and torsion spring, enables manual unlocking of the latch in emergency situations. The manual unlocking structure is simple, occupies little space, and effectively saves costs. The cooperation between the spiral groove and guide block, and the sliding groove and slider, ensures smooth movement of the locking rod, providing a self-centering function, high strength, good impact resistance, high reliability, and long service life. Dynamic waterproofing is achieved through the interference fit between the double-layer sealing soft rubber ring and the locking rod.

[0049] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
