Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and particularly to a new type of chute structure actuator. Background Art

[0002] The fuel filling or charging port box of an automobile has undergone a transformation from a manual cable type to an electric type. In the electric fuel filling port actuator of a traditional motor vehicle, there is only a driving part. Its working principle is that a motor as a power component drives a control unit to move through a transmission system to achieve locking and unlocking.

[0003] The traditional actuator has a large external shape design, which not only greatly wastes space but also brings difficulties to the overall vehicle layout and part installation. Moreover, the inherent structural defects of the traditional actuator result in poor sealing performance. Over time, sundries and water will accumulate inside the parts. The accumulation of sundries will affect the normal operation of the parts, and the accumulation of water will also cause corrosion of the parts. All these will greatly reduce the function and lifespan of the parts. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0028] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

[0029] Next, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments, but it is not a limitation of the present invention.

[0030] The novel chute structure actuator provided in the present invention, referring to Figure 1 and Figure 2 , includes:

[0031] A housing 1, with an opening at one end and multiple groups of guide grooves 13 evenly distributed along the circumference inside. The guide grooves 13 include a first guide slideway 14, a second guide slideway 15, and a locking surface 16. The second guide slideway 15 is connected to the first guide slideway 14, and the locking surface 16 is provided on the second guide slideway 15, so that the first guide slideway 14, the second guide slideway 15, and the locking surface 16 are connected in sequence and closed to form a loop;

[0032] The push rod 2 has one end disposed inside the housing 1, and the other end passes through the opening and can contact the fueling or charging port box, and can perform up and down spiral rotation movements along the axial direction of the push rod shaft hole 11 inside the housing 1;

[0033] The annular block 3 is installed around the push rod 2, and multiple groups of guide ribs 31 evenly distributed along the circumference are arranged on the outer periphery. The guide ribs 31 can be clamped in the first guide slideway 14 and can move along the length direction of the first guide slideway 14, and can also perform displacement along the length direction of the second guide slideway 15. A first guide inclined surface 32 capable of cooperating with the locking surface 16 is provided on the guide ribs 31; and

[0034] The elastic member 5 has two ends respectively abutted against the push rod 2 and the rear cover 4 of the housing 1. In this embodiment, the elastic member 5 is set as a spring, and other elastic members 5 with elastic effects can also be set, which are all within the protection scope of this application.

[0035] In the present invention, the rear cover 4 is welded to the housing 1, and an execution area is formed by enclosing between the rear cover 4 and the housing 1. The push rod 2, the annular block 3 and the elastic member 5 are installed in the execution area. The annular block 3 is installed around the push rod 2 in a fixed clamping form, which can not only make the annular block 3 follow the push rod 2 to move, but also make the annular block move on the push rod 2, and both the push rod 2 and the annular block 3 are installed in the push rod shaft hole 11 inside the housing 1. In the present invention, the push rod 2 can perform up and down spiral rotation movements along the axial direction of the push rod shaft hole 11, the annular block 3 can perform axial movement and spiral rotation movements along the axial direction of the push rod shaft hole 11, and two ends of the elastic member 5 are respectively abutted against the push rod 2 and the rear cover 4 to apply an elastic force to the push rod 2. In the present invention, when the annular block 3 follows the push rod 2 to slide along the first guide slideway 14, then slide along the second guide slideway 15, and then is clamped on the locking surface 16 in the housing 1, the push rod 2 can be locked.

[0036] In addition, a spiral groove 21 is provided on the outer wall of the push rod 2, and a limiting boss 12 matched with the spiral groove 21 is provided on the inner wall of the push rod shaft hole 11. The push rod 2 is clamped on the limiting boss 12 by performing up and down spiral rotation movements along the axial direction of the push rod shaft hole 11 through the spiral groove 21, and can perform up and down spiral rotation movements along the axial direction of the push rod shaft hole 11. Therefore, the external dimension of the actuator can be effectively reduced through the spiral drive design of the push rod 2.

[0037] Four groups of clamping bosses 34 evenly distributed along the circumference are provided on the inner wall of the annular block 3, and a circular groove line matched with the clamping bosses 34 is provided on the outer wall of the push rod 2. The annular block 3 is clamped in the circular groove line through the clamping bosses 34 to realize the axial synchronous movement of the annular block 3 and the push rod 2. Furthermore, through the above clamping form, when the annular block 3 and the push rod 2 are in the first guide slideway 14, the push rod 2 performs a downward spiral rotation movement, and the annular block 3 rotates in the circular groove line of the push rod 2 and can also follow the push rod 2 to move downward together.

[0038] After charging or refueling is completed, overcoming the elastic force exerted by the elastic member 5, the push rod 2 is pushed to perform a spiral movement, and the push rod 2 is squeezed into the interior of the housing 1, so that the guiding ribs 31 on the annular block 3 are pushed out of the first guiding slideway 14 and rotated to the second guiding slideway 15, so that the first guiding inclined surface 32 contacts the locking surface 16.

[0039] The rear cover 4 further includes a plurality of groups of third guiding slideways 41 evenly distributed along the circumference and a fourth guiding slideway 42 connected to the third guiding slideway 41. When the push rod 2 is pressed, the annular block 3 moves downward through the push rod 2, and the second guiding inclined surface 33 contacts the third guiding slideway 41, and the annular block 3 starts to rotate to the fourth guiding slideway 42 through the third guiding slideway 41.

[0040] The guiding rib 31 is further provided with a second guiding inclined surface 33, and the third guiding slideway 41 is provided with a wedge surface 411 adapted to the second guiding inclined surface 33.

[0041] The rear cover 4 is provided with positioning posts 43, and one end of the push rod 2 away from the rear cover 4 is recessed inward to form a mounting hole 23. One end of the elastic member 5 passes through the positioning post 43, and the other end of the elastic member 5 abuts against the mounting hole 23. In the present invention, the elastic member 5 is constrained by the positioning post 43 and the mounting hole 23 to prevent its disturbance during the movement process.

[0042] The inside of the positioning post 43 is hollow, which can save materials and resources.

[0043] Moreover, in this embodiment, the multiple groups are all set to four groups, and can also be set to at least two other groups, all within the protection scope of the present application.

[0044] The present invention further includes an automobile, and the automobile includes the above-mentioned new chute structure actuator.

[0045] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention accordingly. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and drawings of the present invention should be included in the protection scope of the present invention.
