Description

Technical Field

[0001] This utility model relates to a semi-automatic automatic pop-out charging port cover locking actuator. Background Technology

[0002] The charging port cover is a component installed on new energy vehicles to close the charging interface. Currently, the charging port cover can be equipped with an electronic locking actuator or a semi-automatic locking actuator. The semi-automatic locking actuator requires the user to close the charging port cover manually and lock it. At this time, the charging cover can only be opened by electronic unlocking. The current semi-automatic locking actuator has a complex internal structure and lacks a detection feedback device, so the safety performance of the vehicle needs to be improved. Utility Model Content

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 8 As shown, the semi-automatic pop-out charging port cover locking actuator includes a housing 1 and a top cover 2 that cooperate with each other. The housing 1 includes a receiving compartment 11, and a cable tray port 12 is provided at the lower end of the receiving compartment 11. The receiving compartment 11 contains a motor 3, a locking device 4, and a base 5. An opening 21 is provided on one side of the top cover 2. A protective connector 9 is fitted on the cable tray port 12.

[0026] The top cover 2 is provided with a vent hole 23, and a vent membrane is provided on the inner side of the top cover 2 opposite to the vent hole 23. When there is a slight water vapor inside the actuator, the water vapor can be discharged through the vent hole 23.

[0027] The base 5 is located inside the cable tray port 12, and one end of the base 5 includes a hollow sleeve 51; the motor 3 is located above the cable tray port 12, one end of the motor 3 is fixed to the inner wall of the housing 1, and the other end is provided with a worm gear; the locking device 4 includes a locking rod 41, a locking element 42 and a first spring 43; the locking rod 41 cooperates with the opening 21 of the top cover 2, and the top end of the locking rod 41 is provided with a relatively outward protruding latch 411, which is located outside the opening 21. The lower end of the locking rod 41 cooperates with the sleeve 51 and is sleeved on the outside of the sleeve 51. The locking rod 41 can rotate up and down relative to the sleeve 51 and the opening 21. When the charging port cover is in the unlocked state, the locking rod 41 is in the extended state relative to the opening 21 and is located at the upper end of the sleeve 51; when the locking rod 41 rotates into the opening 21 and is located at the lower end of the sleeve 51, the charging port cover is in the locked state.

[0028] A locking opening 412 is provided on the side wall of the locking rod 41. Annular protrusions surrounding the locking rod 41 are provided on both sides of the locking opening 412. When the locking rod 41 is extended relative to the opening 21, the locking opening 412 faces the inner wall of the housing 1. The bottom end of the locking rod 41 is provided with an inwardly inclined first slope 413. A locking member 42 is sleeved on the worm gear. The locking member 42 has a thread inside that mates with the worm gear, and an annular groove 422 is provided on the outer side of the thread. A first spring 43 is sleeved on the worm gear, with one end abutting against the motor 3 and the other end abutting against the groove 422 inside the locking member 42. A locking block 421 is provided outwardly on the side wall of the locking member 42. The side wall of the locking block 421 facing the locking rod 41 has an upwardly inclined second slope that mates with the first slope 413. When… When the locking rod 41 is manually pressed and rotated into the opening 21, the locking port 412 gradually turns to the side of the locking block 421. At the same time, the first slope 413 and the second slope abut against each other, pushing the locking block 421 towards the motor 3. At this time, the entire locking part 42 moves towards the motor 3. When the locking port 412 is opposite to the locking block 421, the entire locking part 42 is reset under the action of the first spring 43. At this time, the locking block 421 enters the interior of the locking port 412, and the charging port cover is locked. When it is necessary to open the charging port cover, the motor 3 needs to drive the worm gear to move the locking part 42 away from the locking port 412. The sleeve 51 is equipped with a second spring that cooperates with the locking rod 41. When the locking part 42 leaves the locking port 412, the locking rod 41 automatically pops out to the outside of the opening 21 under the action of the second spring.

[0029] The lower end of the locking member 42 is provided with a protrusion 423, which extends to the outside of the housing 1. The outer shell 10 is sleeved on the outside of the protrusion 423. The outer shell 10 is slidably connected to the housing 1. The lower end of the outer shell 10 can be connected to a pull rope. When the motor 3 cannot work, the outer shell 10 can be pulled by the pull rope to drive the locking member 42 away from the locking port 412 to achieve manual unlocking.

[0030] A conductive component 6 is provided at the lower end of the base 5. The conductive component 6 includes a first conductive terminal 61 and a second conductive terminal 62, which face the cable tie port 12. The first conductive terminal 61 has two pins, and a detection switch 7 is connected to the tail end. The detection switch 7 is located at the lower end of the base 5, and a detection port 71 is provided at the tail end of the detection switch 7. A conductive rod 8 is provided inside the locking rod 41. The conductive rod 8 is located inside the sleeve 51 and moves up and down with the locking rod 41. When the locking rod 41 is extended relative to the opening 21, the conductive rod 8 is located at the upper end of the sleeve 51 and does not contact the detection port 71. At this time, the system displays that the charging port cover is unlocked. When the locking rod 41 is retracted relative to the opening 21, the conductive rod 8 penetrates the sleeve 51 to the bottom of the sleeve 51 and contacts the detection port 71, thus breaking the detection path. At this time, the system displays that the charging port cover is locked.

[0031] The second spring is sleeved on the outer wall of the conductive rod 8.

[0032] The second conductive terminal 62 has two pins, the tails of which extend upwards to connect with the motor 3, providing power to the motor 3.

[0033] The top of the opening 21 is provided with a sealing ring 22 that cooperates with the locking rod 41. The top of the sealing ring 22 includes a first sealing layer 221 and a second sealing layer 222. An oil storage tank 223 is provided between the first sealing layer 221 and the second sealing layer 222, and the oil storage tank 223 stores lubricating oil.

[0034] This utility model's semi-automatic charging port cover locking actuator connects a locking device 4 to the worm gear of a motor 3. The locking device 4 includes a locking rod 41 and a locking element 42. The locking element 42 is equipped with a locking block 421. When the locking rod 41 is pressed down, the first slope 413 at the lower end of the locking rod 41 pushes the second slope of the locking block 421, pushing the locking block 421 towards the motor 3. When the locking block 421 is opposite to the locking opening 412, the locking block 421 resets under the action of the first spring 43, and one end of the locking block 421 enters the locking opening 412, thereby locking the charging port cover. The locking device has a simple structure, is easy to assemble, and reduces costs. When the charging port cover is locked, the conductive rod 8 abuts against the detection connector 71, causing the detection path to be broken, and the system reminds the user that the charging port cover is in the locked state.

[0035] Finally, it should be noted that the above embodiments only illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
