Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of motor vehicle cover locks, and in particular to a motor vehicle fuel / charging port box cover actuator. Background Art
[0002] To achieve both opening and locking functions, the most commonly used fuel filler cap assembly consists of two components: an ejector actuator and a locking motor. The actuator ejects the fuel filler cap, while the motor rotates a control pin that inserts into the fuel filler cap panel to lock the fuel filler cap, preventing it from opening during driving or when parked. This structure not only requires a large number of parts and requires a long assembly process, but it is also bulky and inefficient, hindering vehicle space utilization.
[0003] When designing an entire vehicle, it's generally important to maximize efficiency while minimizing space to significantly reduce costs. However, traditional actuators are bulky and waste significant space, making both overall vehicle layout and parts assembly difficult. Summary of the Invention
[0004] To solve the above problems, the present invention proposes an actuator for a fuel / charging port cover of a motor vehicle. The specific technical solution is as follows:
[0005] A motor vehicle fuel / charging port cover actuator, comprising:

[0008] A fixing plate is mounted on the inner bottom of the housing in parallel with the push rod, and a guide groove parallel to the axial direction of the push rod is provided on the side of the fixing plate facing the push rod, and a limit platform is provided at the inner bottom end of the guide groove to form a limit groove;
[0009] A slide seat, the outer end of which is slidably sleeved on the fixed plate, the inner end of the slide seat is symmetrically provided with a ring arm, and the ring arm is provided with a ring block that can limit the sliding movement in the annular groove; and
[0010] A rotating block, which may be located in the guide groove or the limiting groove and rotatably mounted on the outer end surface of the slide;
[0011] The push rod is provided with a compression spring, and the other end of the compression spring is connected to the positioning column; by pressing the pushing part of the push rod, the rotating block can move from the guide groove to the limiting groove, and the rotating block rotates to a state restricted by the limiting platform, so that the push rod is in a retracted state with restricted rebound, or the rotating block rotates to a position not restricted by the limiting platform, and the rotating block can move from the limiting groove to the guide groove, so that the push rod is in a pop-up state that rebounds to the outside of the shell under the action of the rebound force of the compression spring.
[0012] Furthermore, guide plates are provided on the tops of both inner sides of the guide groove, and sliding grooves matching the guide plates are provided on both sides of the outer end of the slide seat.
[0013] Furthermore, a rotating hole is provided on the outer end surface of the sliding seat, and a rotating table which can be restricted to rotate in the rotating hole is provided on the rotating block.
[0014] Furthermore, the limit platform includes at least a first wedge block and a second wedge block, and the first wedge block and the second wedge block are respectively arranged at two positions diagonally opposite to each other in the limit groove, and the first wedge groove and the second wedge groove are symmetrically opened at both ends of the rotating block. The first wedge groove or the second wedge groove moves to the second wedge block to interfere and drive the rotating block to rotate. The rotating block rotates to the position where the first wedge block is embedded in the first wedge groove or the second wedge groove and is restricted from rotating, so that the push rod is in a retracted state.
[0015] Furthermore, the inner edge of the first wedge groove or the second wedge groove in the pop-up state is opposite to the tip of the second wedge block, and the outer edge of the first wedge groove or the second wedge groove in the retracted state is opposite to the tip of the second wedge block.
[0016] Furthermore, a blocking block is provided in the limiting groove at a position laterally opposite to the second wedge block.
[0017] Furthermore, a rotation groove communicating with the limiting groove is formed on the inner side of the guide groove transversely opposite to the first wedge block, so that the rotating block can rotate in the rotation groove.
[0018] Furthermore, the distance between the bottom end of the push rod and the inner bottom end of the shell is not less than the vertical distance between the first wedge block and the second wedge block.
[0019] Furthermore, the horizontal arc length of the spiral groove can enable the push rod to rotate to an angle of not less than 90°, and the vertical length of the spiral groove can enable the push rod to move to a distance not less than the vertical distance between the first wedge block and the second wedge block.
[0020] Furthermore, a sealing soft rubber which is interference-fitted with the push rod is provided on the inner side of the top of the shell.

Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.
[0035] like Figures 1 to 6 As shown, an actuator for a fuel / charging port cover 7 of a motor vehicle includes a housing 1, a push rod 2, a fixing plate 3, a slide 4, and a rotating block 5; specifically:
[0036] A protrusion 11 is provided on the inner wall of the housing 1 , and a positioning column 12 is provided on the inner bottom of the housing 1 .
[0037] The push rod 2 is movably mounted within the housing 1. The outer end of the push rod 2 extends beyond the housing 1 to form a push portion 21. The outer surface of the push rod 2 within the housing 1 is provided with an annular groove 22 arranged along the periphery and a spiral groove 23 for the sliding movement of the protrusion 11. The push rod 2 within the housing 1 has a cylindrical structure, and the housing 1 is immovable. When the push rod 2 moves relative to the inner bottom of the housing 1, the push rod 2 simultaneously rotates and moves vertically, constrained by the spiral groove 23 and the protrusion 11.
[0038] In one embodiment, a sealing soft glue 13 is provided on the inner side of the top of the housing 1 and is interference-fitted with the push rod 2 to achieve the functions of sealing, waterproofing and buffering.
[0039] The fixing plate 3 is installed on the inner bottom of the shell 1 in parallel with the push rod 2. The side of the fixing plate 3 facing the push rod 2 is provided with a guide groove 31 parallel to the axial direction of the push rod 2. The inner bottom end of the guide groove 31 is provided with a limit platform that can form a limit groove 33.
[0040] The outer end of the slide 4 is slidably mounted on the fixed plate 3. The inner end of the slide 4 is symmetrically provided with ring arms 41. Each ring arm 41 is provided with a ring block 42 that is constrained to slide within the annular groove 22. The inner end of the slide 4 and the two ring arms 41 surround the outer wall of the push rod 2. When the push rod 2 rotates, causing the annular groove 22 to rotate synchronously, the slide 4 can only slide along the fixed plate 3 and cannot rotate. As a result, the ring blocks 42 on the ring arms 41 slide relative to each other within the annular groove 22, causing the push rod 2 to drive the slide 4 to move vertically synchronously.
[0041] The rotating block 5 can be located in the guide groove 31 or the limiting groove 33 and can be rotatably mounted on the outer end surface of the slide 4; when the slide 4 slides along the fixed plate 3, the position of the rotating block 5 moves along with the slide 4.
[0042] The push rod 2 is provided with a compression spring 6, the other end of which is connected to the positioning column 12. By pressing the pushing portion 21 of the push rod 2, the rotating block 5 can move from the guide groove 31 to the limiting groove 33, and the rotating block 5 rotates to a state restricted by the limiting platform, so that the push rod 2 is in a retracted state where rebound is restricted. At this time, the compression spring 6 is in an initial state where it is compressed and generates a rebound force. By pressing the pushing portion 21 of the push rod 2 again, the rotating block 5 can also be rotated to a position where it is not restricted by the limiting platform. The rotating block 5 can move from the limiting groove 33 to the guide groove 31, so that the push rod 2 is in an ejected state where it rebounds outward from the housing 1 under the action of the rebound force of the compression spring 6. At this time, the compression spring 6 is in an uncompressed working state.
[0043] It should be noted that the description of each aspect of this application is based on Figure 1 The relative positions of the components shown in the figure shall prevail; among them, the end of the shell 1 connected to the positioning post 12 is the "bottom", and the other end is the "top"; the movement toward the bottom of the shell 1 is the "inward" movement, and the movement away from the bottom of the shell 1 is the "outward" movement; the side or end of each component close to the positioning post 12 is the "inside" or "inner end", the direction in which the compression spring 6 is compressed is the "vertical" or "perpendicular", and the direction perpendicular to the "vertical" is the "lateral" or "horizontal".
[0044] like Figure 3 、 4 As shown in Figure 6, guide plates 32 are provided on the top of both inner sides of the guide groove 31, and sliding grooves 43 matching the guide plates 32 are opened on both sides of the outer end of the slide 4, so that when the push rod 2 drives the slide 4 to move, the slide 4 can slide on the guide plate 32 along the fixed plate 3.
[0045] like Figure 1 、 4As shown in Figures 6 and 7, a rotating hole 51 is provided on the outer end surface of the slide seat 4, and a rotating table 52 is provided on the rotating block 5 which can be restricted to rotate in the rotating hole 51, so that the rotating block 5 can rotate around the rotating table 52.
[0046] like Figure 6 As shown, the limit platform includes at least a first wedge block 34 and a second wedge block 35, and the first wedge block 34 and the second wedge block 35 are respectively arranged at two positions diagonally opposite to each other in the limit groove 33, and the first wedge groove 53 and the second wedge groove 54 are symmetrically opened at both ends of the rotating block 5. The first wedge groove 53 or the second wedge groove 54 moves to the second wedge block 35 to interfere and drive the rotating block 5 to rotate. The rotating block 5 rotates to the position where the first wedge block 34 is embedded in the first wedge groove 53 or the second wedge groove 54 and is restricted from rotating, so that the push rod 2 is in a retracted state.
[0047] In one embodiment, the inner edge of the first wedge groove 53 or the second wedge groove 54 in the pop-up state is opposite to the tip of the second wedge block 35, and the outer edge of the first wedge groove 53 or the second wedge groove 54 in the retracted state is opposite to the tip of the second wedge block 35.
[0048] Preferably, a rotation groove 37 connected to the limit groove 33 is opened on the inner side of the guide groove 31, and the rotation groove 37 is horizontally opposite to the first wedge block 34. When the rotating block 5 rotates until the first wedge block 34 is tightly against the outer side of the first wedge groove 53 or the second wedge groove 54, the rotating block 5 can be pushed by the first wedge block 34 and rotate in the rotation groove 37 without interference, so that the rotating block 5 can rotate from the limit groove 33 to a position where it can move in the guide groove 31.
[0049] By utilizing the interaction between the limit platform and the rotating block 5 and the regular changes in the rotation position of the rotating block 5, when the pushing portion 21 of the push rod 2 is continuously pressed, the push rod 2 can be alternately in the retracted state and the pop-up state, thereby realizing the "Push-Push" function of the push rod 2.
[0050] like Figure 1 、 2 As shown, the distance between the bottom end of the push rod 2 and the bottom end of the housing 1 is not less than the vertical distance between the first wedge block 34 and the second wedge block 35, so that the rotating block 5 can be rotated to a position where it can be rotated by the second wedge block 35.
[0051] Preferably, the horizontal arc length of the spiral groove 23 allows the push rod 2 to rotate by an angle of not less than 90°, and the vertical length of the spiral groove 23 allows the push rod 2 to move by a distance not less than the vertical distance between the first wedge block 34 and the second wedge block 35.
[0052] like Figure 6As shown in the figure, the compression spring 6 is in an uncompressed working state, and the push rod 2 is in a pop-up state; at this time, the push rod 2 pushes the box cover 7 of the fuel inlet or charging port, so that one side of the box cover 7 is pushed outward a certain distance, making it easier to open the box cover 7.
[0053] Specifically, if Figure 5 As shown, in the existing design, a long hinge hole 71 is provided in the box cover 7 of the fuel filler port or the charging port, and a push plate 72 is provided directly above the hinge hole 71. A limiting plate 24 that can pass through the hinge hole 71 is provided on the pushing portion 21, and the limiting plate 24 extends out of the hinge hole 71 and is located directly below the pushing plate 72. When the push rod 2 is in the pop-up state, the limit plate 24 is parallel to the hinge hole 71, and the limit plate 24 pushes on the pushing plate 72 to push the box cover 7 open; when the push rod 2 is in the retracted state, the push rod 2 rotates 90° under the guidance of the spiral groove 23, so that the limit plate 24 rotates to a position perpendicular to the hinge hole 71. At this time, the limit plate 24 cannot pass through the hinge hole 71, and the box cover 7 is restricted by the limit plate 24 and cannot be opened outward, so the limit plate 24 is used to lock the box cover 7 to avoid accidental opening of the box cover 7 due to factors such as vibration.
[0054] by Figure 6 The state of the middle rotating block 5 is an embodiment to illustrate the “Push-Push” function, wherein the rotating block 5 has a first wedge groove 53 at one end close to the pushing portion 21 and a second wedge groove 54 at the other end.
[0055] like Figure 7 As shown in the figure, the process of the compression spring 6 changing from the working state to the initial state is shown in Figures (a) to (d). The cover 7 of the fuel filler or charging port has a certain elasticity. When the cover 7 is pressed, the cover 7 pushes the pushing portion 21 of the push rod 2, thereby moving the push rod 2 from the popped-out state to the retracted state. The specific process is as follows:
[0056] As shown in Figure (a), pushing the push rod 2 causes it to move inward, and the push rod 2 rotates synchronously under the action of the spiral groove 23, causing the limit plate 24 to rotate. At this time, the push rod 2 drives the slide 4 to slide inward along the fixed plate 3 on the guide plate 32, so that the rotating block 5 moves from the guide groove 31 to the limit groove 33, and moves the rotating block 5 to the point where the inner edge of the second wedge groove 54 is opposite the tip of the second wedge block 35.
[0057] As shown in FIG. (b), the rotating block 5 continues to move inward, and under the push of the second wedge block 35, the rotating block 5 rotates counterclockwise until the second wedge groove 54 is just embedded in the second wedge block 35. At this time, the push rod 2 can no longer move inward, and the compression spring 6 is in a compressed state.
[0058] As shown in Figure (c), the pushing force of the box cover 7 is removed, the push rod 2 loses its force and moves outward under the action of the rebound force of the compression spring 6. At this time, the rotating block 5 maintains the inclined state in Figure (b) to follow the push rod 2 to move outward and move until the tip of the first wedge block 34 is opposite to the inner edge of the first inclined groove;
[0059] As shown in Figure (d), under the push of the first wedge block 34, the rotating block 5 rotates counterclockwise until the first wedge groove 53 is just embedded in the first wedge block 34; due to the limitation of the width of the first wedge block 34 and the limiting groove 33, the rotating block 5 cannot continue to rotate counterclockwise, and the rotating block 5 is restricted in the limiting groove 33. At this time, the compression spring 6 is still in a compressed state, the push rod 2 is in a retracted state, and under the action of the spiral groove 23, the push rod 2 rotates forward 90°, so that the limiting plate 24 is in a state of locking the box cover 7, so that the push rod 2 is in a "Push-Push" retracted state.
[0060] like Figure 8 As shown in the figure, the process group diagrams (e) to (h) show the process of the compression spring 6 changing from the initial state to the working state; when the box cover 7 is pressed again, the box cover 7 pushes the pushing portion 21 of the push rod 2, thereby moving the push rod 2 from the retracted state to the ejected state. The specific process is as follows:
[0061] As shown in FIG. (e), the push rod 2 is pushed so as to move inward, and the rotating block 5 maintains the tilted state shown in FIG. (d) to follow the push rod 2 inward and move until the outer edge of the second wedge groove 54 is opposite to the tip of the second wedge block 35;
[0062] (f) As shown in the figure, the rotating block 5 continues to move inward, and under the push of the second wedge block 35, the rotating block 5 rotates counterclockwise until the rotating block 5 is restricted by the limit groove 33 and cannot continue to rotate. At this time, the push rod 2 can no longer move inward, and the compression spring 6 is in a compressed state;
[0063] Preferably, a blocking block 36 can also be set in the limiting groove 33 at a position laterally opposite to the second wedge block 35 to limit the rotating block 5 from excessive rotation under the inertia pushed by the second wedge block 35, thereby preventing the rotating block 5 from being unable to enter the guide groove 31.
[0064] As shown in FIG (g), the pushing force of the box cover 7 is removed, the push rod 2 loses its force and moves outward under the action of the rebound force of the compression spring 6. At this time, the rotating block 5 maintains the inclined state shown in FIG (f) to follow the push rod 2 to move outward and move until the tip of the first wedge block 34 is opposite to the outside of the first inclined slot;
[0065] As shown in Figure (h), under the push of the first wedge block 34, the rotating block 5 continues to rotate counterclockwise and rotates in the rotating groove 37, so that the rotating block 5 rotates into the guide groove 31. At this time, the push rod 2 quickly rebounds under the action of the rebound force of the compression spring 6; at the same time, under the action of the spiral groove 23, the push rod 2 rotates 90° in the opposite direction, so that the limit plate 24 on the push rod 2 rotates to a position parallel to the hinge hole 71, and quickly pushes the push plate 72 above the hinge hole 71, thereby pushing one side of the box cover 7 outward by a certain distance to facilitate opening the box cover 7, and the push rod 2 is in a "Push-Push" pop-up state.
[0066] Figure 7 、 8 The group of pictures completes a "Push-Push" retraction-ejection function. At this time, the rotating block 5 rotates 180°, and the positions of the first wedge groove 53 and the second wedge groove 54 opened on the rotating block 5 are swapped; when the push rod 2 is pressed again, since the first wedge groove 53 and the second wedge groove 54 are symmetrically arranged, the rotating block 5 can repeat the above action to repeatedly complete the "Push-Push" function.
[0067] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of this application is defined by the appended claims and their equivalents.
