[0022] 2. The novel motor vehicle refueling or charging port box actuator and the automobile described in the present invention, after charging or refueling is completed, overcome the elastic force applied by the elastic member, squeeze the push rod into the shell, and then simultaneously drive the second sleeve to move, so that the second sleeve interacts with the first sleeve and the shell, locks the push rod, retracts and locks the push rod relative to the refueling or charging port box, and prevents the push rod from contacting the refueling or charging port box for charging or refueling. When charging or refueling is needed, the push rod is rotated relative to the shell, so that the push rod cooperates with the refueling or charging port box and is pressed by the elastic member, which can prevent the push rod from falling out.

[0041] A new type of motor vehicle refueling or charging port box actuator, referring to Figure 1-Figure 7 As shown, it includes a housing 1, a push rod 2, a first sliding sleeve 3, a second sliding sleeve 4 and an elastic member 5. The push rod 2 can contact with the refueling or charging port box and be locked in the refueling or charging port box.

[0042] Reference Figure 3 As shown, a contact groove 121 is provided on the inner wall of the shell 1. The contact groove 121 includes a first guide slide 1211 and a locking surface 1212. The locking surface 1212 is provided above the first guide slide 1211 and is spaced a certain distance from the first guide slide 1211. An opening is provided at the bottom of the shell 1.

[0043] Reference Figure 6 and Fig. 9As shown, one end of the push rod 2 is arranged in the housing 1, and the other end passes through the opening and can contact the refueling or charging port box, and the push rod 2 can move up and down or rotate in the housing 1. The other end of the push rod 2 is also provided with a push ear 21, which is convenient for applying force to the push rod 2 so that the push rod 2 can move up and down or rotate in the housing 1. In the embodiment of the present invention, the push rod 2 is provided with two push ears 21, and the two push ears 21 are symmetrically arranged relative to the push rod 2.

[0044] Reference Figure 3 , Figure 4 and Fig. 9 As shown, the first sleeve 3 is arranged in the shell 1 and on the top of the push rod 2. A limiting groove 1213 is provided on the inner wall of the shell 1 to limit the rotation of the first sleeve 3, so that the first sleeve 3 can only move up and down in the shell 1. A guide surface 311 is provided on the top of the first sleeve 3.

[0045] Specifically, a guide rib 31 is provided on the first sliding sleeve 3 , a guide surface 311 is provided on the top of the guide rib 31 , and the guide rib 31 is arranged in the limiting groove 1213 , so that the first sliding sleeve 3 moves up and down along the extension direction of the limiting groove 1213 under the constraint of the limiting groove 1213 .

[0046] Reference Figure 4 , Figure 5 and Fig. 9 As shown, the second sleeve 4 is fixed on the push rod 2 and is provided with a guide protrusion 41. The guide protrusion 41 extends out of the push rod 2 and is arranged on the top of the first sleeve 3. The guide protrusion 41 can be stuck in the first guide slide 1211 and can move up and down along the first guide slide 1211. A contact surface 411 that can cooperate with the locking surface 1212 or the guide surface 311 is provided at the bottom of the guide protrusion 41. When the guide protrusion 41 moves upward and slides out of the first guide slide 1211, the first sleeve 3 can rotate with the push rod 2.

[0047] Reference Figure 7 and Fig. 9 As shown, the elastic member 5 is arranged in the shell 1 and its two ends are respectively connected to the shell 1 and the push rod 2. The elastic member 5 can be a spring for applying elastic force to the push rod 2. When the guide protrusion 41 needs to move upward along the first guide slide 1211, the elastic force applied by the elastic member 5 needs to be overcome.

[0048] After charging or refueling is completed, the elastic force applied by the elastic member 5 is overcome, and the push rod 2 is squeezed toward the inside of the shell 1, so that the guide protrusion 41 of the second sleeve 4 is pushed out from the first guide slide 1211, and the contact surface 411 contacts the guide surface 311 and the locking surface 1212 in sequence. When the contact surface 411 cooperates with the locking surface 1212, the locking surface 1212 can lock the guide protrusion 41, so that the guide protrusion 41 cannot move downward. Since the second sleeve 4 is fixed on the push rod 2, the push rod 2 cannot move downward. The push rod 2 is retracted and locked relative to the refueling or charging port box to prevent the push rod 2 from contacting the refueling or charging port box for charging or refueling.

[0049] When charging or refueling is required, the push rod 2 is rotated relative to the shell 1, so that the guide protrusion 41 of the second sleeve 4 rotates and slides into the first guide slide 1211. The push rod 2 is matched with the refueling or charging port box and is pressed by the elastic member 5 to prevent the push rod 2 from falling out and affecting the charging or refueling effect.

[0050] The present invention compactly designs the push rod 2, the first sliding sleeve 3, the second sliding sleeve 4 and the elastic member 5 in the housing 1, thereby effectively reducing the external dimensions of the actuator.

[0051] In one embodiment, referring to Figure 3-Figure 5 As shown, in order to achieve continuous movement of the structure, multiple groups of contact grooves 121 are provided and are centrally symmetrically distributed in the housing 1, and the limit grooves 1213 are provided in the contact grooves 121 and are spaced a certain distance from the first guide slideway 1211. To facilitate the retraction or insertion of the push rod 2 from the refueling or charging port box, the second slide sleeve 4 is provided with multiple centrally symmetrically distributed guide protrusions 41, and each guide protrusion 41 has a contact surface 411 at the bottom, and the first slide sleeve 3 is provided with multiple centrally symmetrically distributed guide surfaces 311.

[0052] In the embodiment of the present invention, four groups of contact grooves 121 are provided and are centrally symmetrically distributed in the housing 1, four centrally symmetrically distributed guide protrusions 41 are provided on the second sliding sleeve 4, and four centrally symmetrically distributed guide surfaces 311 are provided on the first sliding sleeve 3.

[0053] In one embodiment, the first sleeve 3 is an annular structure, and is provided with a plurality of guide ribs 31 which are centrally symmetrically distributed. The top of the guide rib 31 is V-shaped, which facilitates the guide protrusion 41 to be clamped in the guide rib 31. One surface of the top of the guide rib 31 is a guide surface 311. When the push rod 2 moves, the guide protrusion 41 is clamped in the guide rib 31, so that the push rod 2 drives the first sleeve 3 and the second sleeve 4 to move up and down at the same time. However, due to the setting of the limiting groove 1213, the push rod 2 cannot drive the second sleeve 4 to rotate, and can only drive the first sleeve 3 to rotate.

[0054] In the embodiment of the present invention, four guide ribs 31 are provided on the first sliding sleeve 3 and are distributed symmetrically around the center.

[0055] The second sliding sleeve 4 is a cylindrical structure. One end of the second sliding sleeve 4 is fixed in the push rod 2 , and the other end is provided with a plurality of guide protrusions 41 .

[0056] In order to fix the second sliding sleeve 4 in the push rod 2, refer to Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, a clamping joint 42 is provided on the second sleeve 4, a clamping groove 24 is provided on the push rod 2, and a clamping spring 6 is provided between the clamping joint 42 and the clamping groove 24. When the push rod 2 moves, the second sleeve 4 can be driven to move. Through the interaction of the second sleeve 4, the first sleeve 3, the elastic member 5 and the housing 1, the movement of the push rod 2 can be limited, so that the push rod 2 can be retracted or pushed in from the refueling or charging port box.

[0057] Reference Figure 3 As shown, the contact groove 121 also includes a second guide slide 1214. The first guide slide 1211, the limit groove 1213 and the second guide slide 1214 are sequentially arranged in the contact groove 121. By providing the second guide slide 1214, it is convenient for the push rod 2 to continue to move and slide into the first guide slide 1211.

[0058] In one embodiment, in order to facilitate the contact between the guide surface 311 and the locking surface 1212, the locking surface 1212, the guide surface 311 and the contact surface 411 are all inclined surfaces. When the push rod 2 is pushed, the guide surface 311 can easily slide toward the locking surface 1212 through the contact surface 411.

[0059] In the above embodiment, referring to Figure 6 and Figure 3 As shown, in order to facilitate the application of an oblique force to the guide protrusion 41 so that the guide surface 311 slides toward the locking surface 1212 through the contact surface 411, a spiral groove 23 is provided on the outer wall of the push rod 2, and a boss 122 is provided on the inner wall of the housing 1. The boss 122 is provided below the limiting groove 1213 and is clamped in the spiral groove 23. When the push rod 2 is pushed, the push rod 2 can perform a spiral motion along the height direction of the limiting groove 1213 under the restraint of the boss 122.

[0060] After charging or refueling is completed, the elastic force applied by the elastic member 5 is overcome, the push rod 2 is pushed to make a spiral motion, and the push rod 2 is squeezed into the shell 1, so that the guide protrusion 41 of the first sleeve 3 is pushed out from the first guide slide 1211, and the inclined contact surface 411 contacts the inclined guide surface 311 and the inclined locking surface 1212 in turn.

[0061] In one embodiment, referring to Figure 2As shown, a spring positioning column 111 is provided in the housing 1, and an inwardly recessed spring positioning groove 22 is provided on the push rod 2. One end of the spring is provided on the spring positioning column 111, and the other end is provided in the spring positioning groove 22. The spring is constrained by means of the spring positioning column 111 and the spring positioning groove 22 to prevent disturbance during its movement, so that the elastic force of the spring acts evenly on the push rod 2.

[0062] In one embodiment, referring to Figure 1-Figure 3 As shown, the housing 1 includes an upper housing 11 and a lower housing 12, and the upper housing 11 and the lower housing 12 are snap-fitted. The upper housing 11 is a cavity structure with one end open, and the lower housing 12 is a structure that is through-through from top to bottom. A spring positioning column 111 is provided on the inner side of the top of the upper housing 11, and a contact groove 121 is provided on the inner wall of the lower housing 12. In the present invention, two symmetrical upper wings 12 are provided on the upper housing 11, and two symmetrical lower wings 123 are provided on the lower housing 12. The upper housing 11 and the lower housing 12 are snap-fitted through the upper wings 12 and the lower wings 123.

[0063] The present invention also includes a car, which includes a novel motor vehicle refueling or charging port box actuator.

[0064] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
