DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-6 An invisible door handle actuator comprises an actuator body 1 , wherein the actuator body 1 comprises a lower cover 11 , an upper cover 12 , and a driving assembly 14 arranged between the lower cover 11 and the upper cover 12 .

[0019] The driving assembly 14 includes a motor 141, a motor worm 142 arranged on the output shaft of the motor 141, a transmission worm wheel 143 transmission-connected to the motor worm 142, a transmission worm 144 arranged on the transmission worm wheel 143, an ejection worm 145 transmission-connected to the transmission worm 144, and a motor sealing ring 148. One end of the ejection worm 145 is a threaded section 146, and the other end is a smooth rod section 147. The interior of the lower cover 11 and the upper cover 12 are jointly provided with a screw thread 171 threadedly sleeved with the threaded section 146, so that the ejection worm 145 can perform axial movement while performing circumferential movement.

[0020] The lower cover 11 and the upper cover 12 are provided with a motor compartment 13 for installing the motor 141. A circle of welding line positions 131 are provided at the joint of the motor compartment 13 inside the lower cover 11 and the upper cover 12. The motor sealing ring 148 is embedded in one side of the motor compartment 13 and is sleeved with the output shaft of the motor 141.

[0021] As a specific technical solution of this embodiment, the motor worm 142, transmission worm wheel 143, transmission worm 144 and ejection worm 145 are all made of PA46 material. The product can withstand high temperature of 85 degrees without deformation. The transmission worm wheel 143 and the transmission worm 144 are both inclined and have an optimal total transmission ratio of 34.67. The output force is increased by 15%, so that the product can work normally under extreme conditions and the performance output consistency is good. The length of the worm section in the middle of the ejection worm 145 is greater than the maximum length of the optical rod section 147 to make telescopic movement to the outside of the installation position three 17.

[0022] As a specific technical solution of this embodiment, after the lower cover 11 and the upper cover 12 are closed, the welding line positions 131 on the lower cover 11 and the upper cover 12 are connected, and a circle of welding line positions 131 are welded by laser welding process to achieve the sealing of the motor compartment 13. The sealing level can reach IP67 waterproof level, which effectively protects the normal operation of the motor 141.

[0023] As a specific technical solution of this embodiment, the lower cover 11 and the upper cover 12 are jointly provided with a mounting position 15, a mounting position 2 16 located on one side of the mounting position 15, and a mounting position 3 17 located on one side of the mounting position 2 16. The motor worm 142 is rotatably arranged inside the mounting position 15, the transmission worm 144 is fixedly connected to the transmission worm wheel 143, the transmission worm 144 and the transmission worm wheel 143 are jointly rotatably arranged inside the mounting position 2 16, and the ejection worm 145 is rotatably arranged inside the mounting position 3 17.

[0024] In the present embodiment, the shape of the mounting position 15 matches the motor worm 142, ensuring the stability of the rotation process of the motor worm 142, and the shape of the mounting position 2 16 matches the transmission worm 144 and the transmission worm wheel 143. Since the transmission worm 144 and the transmission worm wheel 143 are arranged at an angle to maintain the optimal transmission ratio, the setting of the mounting position 2 16 can make the rotation process of the transmission worm 144 and the transmission worm wheel 143 more stable, and the setting of the mounting position 3 17 can make the rotation process of the ejection worm 145 more stable.

[0025] As a specific technical solution of this embodiment, a socket mounting position 111 connected to the interior of the motor compartment 13 is provided on one side of the lower cover 11, and a power socket 18 electrically connected to the motor 141 is provided inside the socket mounting position 111. One end of the power socket 18 extends to the outside of the socket mounting position 111, and a card slot 181 is provided on a section of the power socket 18 located inside the socket mounting position 111, and a socket sealing ring 182 is movably connected inside the card slot 181.

[0026] In this embodiment, the power socket 18 can be connected to a power adapter to supply power to the motor 141. After the lower cover 11 and the upper cover 12 are closed, the power socket 18 is fixed inside the socket mounting position 111, and the socket sealing ring 182 is wrapped around the outer circle of the power socket 18. Since the power socket 18 does not need to rotate like the output shaft of the motor 141, the sealing between the power socket 18 and the socket mounting position 111 can be achieved by cooperating with the socket sealing ring 182 through the slot 181.

[0027] As a specific technical solution of this embodiment, the top of one end of the power socket 18 located inside the socket mounting position 111 and the top of the socket mounting position 111 are both provided with at least one positioning groove 19 whose positions correspond to each other, and the bottom of the upper cover 12 is provided with a positioning block 121 with one end extending into the positioning groove 19, and the number of the positioning blocks 121 is at least one.

[0028] In this embodiment, after the lower cover 11 and the upper cover 12 are closed, the positioning block 121 is inserted from the positioning groove 19 at the top of the socket mounting position 111 into the positioning groove 19 at the top of the power socket 18 to lock the power socket 18, and the number of the positioning groove 19 and the positioning block 121 are not less than one, which further ensures the stability of the power socket 18.

[0029] As a specific technical solution of this embodiment, a sealing hole 132 connected to the interior of the mounting position 15 is provided on one side of the motor compartment 13, the motor sealing ring 148 is nested in the sealing hole 132, and a bevel block 133 is provided in the sealing hole 132, one side of which is in conflict with one side of the motor sealing ring 148.

[0030] In the present embodiment, the sealing hole 132 is used to install the motor sealing ring 148. The inclined block 133 is arranged so that when the motor sealing ring 148 is sleeved on the output shaft of the motor 141 and pressed into the interior of the sealing hole 132, as the motor sealing ring 148 is pressed in, the inclined block 133 will contact one side of the motor sealing ring 148. Following the slope of the inclined block 133, the motor sealing ring 148 is pushed to move laterally along the axial direction of the conveying shaft of the motor 141, so that the side of the motor sealing ring 148 with the airbag 1486 contacts the end cover at one end of the motor 141, so that the airbag 1486 is compressed.

[0031] As a specific technical solution of this embodiment, the screw thread 171 is arranged inside one end of the mounting position three 17, and a sealing hole 2 172 is arranged inside the other end of the mounting position three 17. The end of the optical rod segment 147 away from the ejection worm 145 extends to the outside of the mounting position three 17, and an optical rod sealing ring 149 is movably sleeved on the optical rod segment 147, and the outside of the optical rod sealing ring 149 is sleeved with the inside of the sealing hole 2 172.

[0032] In this embodiment, the polished rod section 147 performs telescopic movement simultaneously with the forward and reverse rotation of the ejection worm 145. The setting of the polished rod sealing ring 149 ensures the sealing of the connection between the end of the polished rod sealing ring 149 and the lower cover 11 and the upper cover 12, and ensures the sealing of the actuator body 1. The sealing hole 172 clamps the polished rod sealing ring 149, which ensures the stability of the polished rod sealing ring 149. Figure 4 Since the thread 171 has only two turns, this design not only allows the thread segment 146 to move forward and backward when rotating, but also greatly reduces the friction of the thread segment 146, making the worm 145 more flexible.

[0033] As a specific technical solution of this embodiment, the motor sealing ring 148 includes a skeleton 1481 and a rubber sleeve 1482 covered on the outside of the skeleton 1481, and the inner ring of the rubber sleeve 1482 is provided with at least one main lip 1483 and an auxiliary lip 1484 located on one side of the main lip 1483, and the main lip 1483 and the auxiliary lip 1484 are both connected to the output shaft of the motor 141.

[0034] In this embodiment, multiple main lips 1483 and auxiliary lips 1484 realize multiple sealing, so that the sealing between the motor sealing ring 148 and the output shaft of the motor 141 is better and no leakage occurs.

[0035] As a specific technical solution of this embodiment, the internal movable sleeve of the rubber sleeve 1482 is provided with a spring tube 1485 located on the outside of the main lip 1483, and the main lip 1483 and the auxiliary lip 1484 and the auxiliary lips 1484 are filled with lubricating media. A circle of airbags 1486 is provided on the side of the rubber sleeve 1482 away from the inclined block 133.

[0036] In this embodiment, the lubricating medium is lubricating oil or other lubricating medium with the same lubricating effect and used for sealing the output shaft of motor 141. The setting of the lubricating medium not only maintains good sealing between the motor sealing ring 148 and the output shaft of motor 141, but also greatly reduces the friction between the two and will not affect the rotation of the output shaft of motor 141. The setting of spring tube 1485 further ensures the contact stability between the main lip 1483, the auxiliary lip 1484 and the output shaft of motor 141.

[0037] As a specific technical solution of this embodiment, a circle of expansion cavity 1487 is arranged inside the outer ring of the rubber sleeve 1482, a circle of corrugated section 1488 corresponding to the expansion cavity 1487 is arranged outside the outer ring of the rubber sleeve 1482, and a plurality of metal tubes 1489 for connecting the airbag 1486 and the expansion cavity 1487 are arranged inside one side of the outer ring of the rubber sleeve 1482.

[0038] In this embodiment, when the airbag 1486 moves sideways with the motor sealing ring 148 and hits the end cover at one end of the motor 141, after the airbag 1486 is squeezed, the gas inside it is transported to the inside of the expansion chamber 1487 through the metal tube 1489, causing the expansion chamber 1487 to expand. The expansion chamber 1487 pushes up the corrugated section 1488 to hit the inner wall of the sealing hole 132, thereby ensuring the sealing between the motor sealing ring 148 and the sealing hole 132. The rubber sleeve 1482 is made of a thicker material, which can avoid being melted and cracked during welding, resulting in leakage of the expansion chamber 1487 or the airbag 1486. ​​The rubber sleeve 1482 can be further thickened at a later stage to increase its strength. The provision of the metal tube 1489 avoids the expansion of the rubber outside the metal tube 1489, so that the gas inside the airbag 1486 is accurately transported to the inside of the expansion chamber 1487.

[0039] When in use, the motor sealing ring 148 is installed on the output shaft of the motor 141, and then the motor worm 142 is pressed into the motor 141, and the motor 141 is installed into the motor bin 13 of the lower cover 11, and then the socket sealing ring 182 is sleeved on the power socket 18 and installed into the socket mounting position 111, and then the remaining drive assembly 14 accessories are installed into the corresponding mounting positions of the lower cover 11 and the upper cover 12, and the upper cover 12 is installed into the lower cover 11. After the upper cover 12 and the lower cover 11 are covered, the positioning block 121 is inserted into the positioning groove 19, and the welding lines of the upper cover 12 and the lower cover 11 are butt-jointed, and then a circle of welding line positions 131 are welded by laser welding to achieve the sealing of the motor bin 13, and finally a circle of welding of the lower cover 11 and the upper cover 12 is completed to complete the installation of the lower cover 11 and the upper cover 12. The motor bin 13 is made IP67 waterproof by laser welding of the motor sealing ring 148 and the socket sealing ring 182, which effectively protects the normal operation of the motor 141.

[0040] In summary, the invisible door handle actuator, through the motor sealing ring 148 and the socket sealing ring 182 and laser welding, makes the motor compartment 13 achieve IP67 level waterproof, effectively protects the normal operation of the motor 141, the motor worm 142, the transmission worm wheel 143, the transmission worm 144 and the ejection worm 145 are all made of PA46 material, the product can withstand 85 degrees high temperature without deformation, the transmission worm wheel 143 and the transmission worm 144 are both inclined, with a better total transmission ratio, the output force is greatly improved, so that the product can work normally under extreme conditions and the performance output consistency is good.

[0041] The invisible door handle actuator has multiple main lips 1483 and auxiliary lips 1484 to achieve multiple sealing. Combined with the filling of lubricating medium, it not only maintains good sealing between the motor sealing ring 148 and the output shaft of the motor 141, but also greatly reduces the friction between the two. After the airbag 1486 is squeezed, the gas inside it is transported to the inside of the expansion chamber 1487 through the metal tube 1489, so that the expansion chamber 1487 expands and the corrugated section 1488 hits the inner wall of the sealing hole 132, thereby ensuring the sealing between the motor sealing ring 148 and the sealing hole 132, and further improving the sealing effect of the motor compartment 13.
