[0025] Various specific implementation manners of the present disclosure will be described below with reference to the drawings forming a part of this specification. It should be understood that although directional terms such as "front", "rear", "upper", "lower", "left", "right", "top", "bottom", etc. are used in the present disclosure to describe various example structural parts and elements of the present disclosure, these terms are used herein only for the purpose of convenience of description and are determined based on the example orientations shown in the drawings. Since the embodiments disclosed in the present disclosure can be arranged in different directions, these directional terms are used only as illustrations and should not be regarded as limitations.

[0026] The actuating device of the present disclosure is used to actuate an openable and closable component, for example, a fuel tank and / or a filler door or lid pivotally mounted on a vehicle. The actuating device of the present disclosure has a push-push motion mechanism and an indicating device. The push-push motion mechanism is associated with (or interacts with) the lid to open and close the lid through a push-push operation. The indicating device cooperates with the push-push motion mechanism to remind the operator who is pushing the lid to open and close the lid that the lid should be released and no further pushing is allowed when the lid has been pressed in place. The working principle of the actuating device of the present disclosure can be applied to various types of push-push motion mechanisms, such as the type of push-push motion mechanism described in the applicant's prior application CN22018111232121.8. The push-push motion mechanism in the embodiment of the actuating device of the present disclosure to be introduced in detail below is similar in structure to the push-push motion mechanism in the applicant's prior application CN22018111232121.8, and this prior application is hereby incorporated into the present disclosure in its entirety by reference.

[0027] Figure 1A and 1B show the overall structure of an actuating device 100 according to an embodiment of the present disclosure, wherein, Figure 1A is a perspective view of the actuating device 100 in the first working state, Figure 1B is a partial exploded view of the actuating device 100.

[0028] As Figure 1A and 1B shown, the actuating device 100 includes a housing 110 and a push-push motion mechanism 120 mounted in the housing 110. The push-push motion mechanism 120 includes an axially moving component that can move along its axis X. The axially moving component has a part that can extend out of the housing 110 to interact with a lid (not shown in the figure). The housing 110 includes a top cover 111 and a base 112, and the two are connected to form a cavity for receiving other components of the actuating device 100. A hole 113 is provided in the top cover 111, and the axially moving component of the push-push motion mechanism 120 can partially extend out of the housing through the hole 113. The push-push motion mechanism 120 is configured to move the lid in the open state to the closed state, or move the lid in the closed state to the open state when the lid is pushed from the outside so that the axially moving component of the push-push motion mechanism 120 is pushed into the housing 110 to the maximum extent and then released.

[0029] As Figure 1BAs shown, the actuating device 100 further includes an indicating device 130. The indicating device 130 includes a key leaf spring 132 and a mounting bracket 131. The mounting bracket 131 is used to mount the key leaf spring 132 in the housing. The key leaf spring 132 is used to cooperate with the axial moving component of the push-push motion mechanism 120, so that when the axial moving component of the push-push motion mechanism 120 is pushed into the housing to the maximum extent, it is triggered by the axial moving component to emit a sound, thereby indicating that the lid has been pushed into the housing to the maximum extent (reaching the limit position). When the operator hears the sound feedback from the indicating device 130, it can be judged that the lid has been pushed into the housing to the maximum extent, so that the lid can be released without continuing to push the lid.

[0030] Still as Figure 1B shown, the actuating device 100 further includes a driving member 140, such as a motor, for driving the locking member 145 to extend into the receiving groove 125 of the push-push motion mechanism 120 to lock the push-push motion mechanism 120, and thereby lock the lid in or on the housing 110.

[0031] Figures 2A - 2C shows the specific structure of the push-push motion mechanism 120, where Figure 2A is an exploded view of the push-push motion mechanism 120, Figure 2B is a perspective view of the fixed sleeve of the push-push motion mechanism, Figure 2C is a cross-sectional view taken along the axis of the push-push motion mechanism 120. In addition to showing the push-push motion mechanism 120, Figure 2A also shows the indicating device 130 and the actuating sleeve 10 that cooperate with the push-push motion mechanism 120.

[0032] As Figure 2A and 2C shown, the push-push motion mechanism 120 includes a push rod 210, a control sleeve 220, a control ring 230, a helical spring 240, and a fixed sleeve 250. The control sleeve 220 and the fixed sleeve 250 are sleeved on the push rod 210, the control ring 230 is sleeved on the control sleeve 220, and the helical spring 240 is at least partially received in the push rod 210. The axial moving components of the push-push motion mechanism 120 include the push rod 210 and the control sleeve 220.

[0033] The push rod 210 includes an outer actuating end 211 and an inner actuating end 212 that are oppositely arranged in its axial direction. In the shown example, two oppositely arranged actuating protrusions 216 are formed on the outer actuating end 211. The inner actuating end 212 opposite to the outer actuating end 211 is always located inside the housing 110, and it is at Figure 1Ais invisible. The outer actuating end 211 projects from the housing 110 and is adapted to cooperate with an actuating sleeve 10 fixed to the lid. The actuating sleeve 10 is cup-shaped and has two actuating grooves 15 on its inner side surface, and when the push rod 210 is inserted into the actuating sleeve 10, an actuating projection 216 engages into each of the actuating grooves 15. A part of the actuating groove 15 travels in a spiral manner around the longitudinal axis of the actuating sleeve 10. Thus, the push rod 210 rotatably mounted in the housing 110 is rotated when inserted into the actuating sleeve 10. As an example, in order to be fully inserted into the actuating sleeve, the push rod 210 is rotated by 90°. After being fully inserted into the actuating sleeve 10, the actuating projections 16 are respectively received in the end receiving portions 16 of the actuating grooves 15, so that the actuating sleeve 15 cannot be disengaged from the push rod 210 by an upward axial movement. On the contrary, in order to disengage the actuating sleeve 10 from the push rod 210, the push rod 210 must first be unscrewed from the actuating sleeve 10 along the actuating groove 16. Figure 1A Shown is the state where the lid is opened, in which the actuating sleeve 10 is disengaged from the push rod 210.

[0034] The helical spring 240 is arranged in the base body 112 of the housing 110 and is supported and firmly connected to the bottom surface of the base body 112 by its lower end. The helical spring 240 further extends into a part of the push rod 210 configured as a hollow cylinder. The helical spring 240 surrounds the central journal 218 of the push rod 210 and is supported and firmly attached to the inner surface of the push rod 210 opposite to the bottom surface of the base body 112. In this way, the spring 240 is compressed against its preloading force during the axial movement of the push rod 210 into the housing 110. In addition, during the process of inserting the push rod 210 into the actuating sleeve 10, if the push rod 210 rotates, the spring 240 is twisted against its preloading force.

[0035] The control sleeve 220 is lockingly and rotatably arranged on the inner actuating end 212 of the push rod 210. Thus, the control sleeve 220 rotatable relative to the push rod 210 is driven during the axial movement of the push rod 210 and vice versa. A push-push control surface is constructed on the outer surface of the control sleeve 220. Near the inner actuating end 212 of the push rod, the push rod 210 further has two opposite stop projections 215 on its outer surface.

[0036] As Figure 2A and 2BAs shown, the fixed sleeve 250 is fixed to the housing 110. The fixed sleeve 225 forms a stop surface 254 in the shape of an annular segment, and an inclined surface 256 connected to the stop surface 254. In operation, the stop projection 215 of the control sleeve 220 is guided by the stop surface 254 and the inclined surface 256, as will be described in more detail below. The actuating device 100 may also not be provided with the fixed sleeve 250, but instead the stop surface 254 and the inclined surface 256 are provided on a component of another structure, such as a plate with a hole.

[0037] The control ring 230 surrounds or fits over the control sleeve 220, and a plurality of control protrusions 238 are formed on the inner side surface of the control ring 230. The control protrusions 238 cooperate with a push-push control surface on the outer side surface of the control sleeve 220.

[0038] Still as Figure 2A shown, the push-push control surface on the outer side surface of the control sleeve 220 has a first deflection surface 274 that extends obliquely to the axis of the control ring or the control sleeve 220. At a circumferential distance separated from the first deflection surface 274, the push-push control surface further has a locking groove 276 that opens towards the outer actuating end 211 of the push rod 210. At another circumferential distance separated from the locking groove 276, the push-push control surface has a second deflection surface 278 that extends obliquely to the axis of the control sleeve 220. Since the control ring 230 has a plurality of control protrusions 238 on its inner side surface, accordingly, the design structure of the push-push control surface repeats regularly on the circumference of the control sleeve 220 according to the number of the control protrusions. Therefore, there are as many first deflection surfaces 274, locking grooves 276, and second deflection surfaces 278 as the control protrusions 238 of the control ring 230.

[0039] The control sleeve 220 is also provided with a protrusion 272 that extends axially downward along the control sleeve 220. It can actuate a micro switch (blocked in the figure) as a position switch when the lid is opened and thus indicate the opened position of the lid. In addition, the protrusion 272 can also contact the indicating device 130 when the push rod 210 and the control sleeve 220 are pushed into the housing to the maximum extent, and trigger the indicating device 130 to emit a sound to indicate that the lid has been pushed into the housing to the maximum extent and it can be released. Therefore, the protrusion 272 also forms a triggering structure for triggering the indicating device 130.

[0040] Figures 3A - 3D Shows the specific structure of the indicating device 130 of the present disclosure, and its installation manner with the housing 110. Among them, Figure 3A is a perspective view of the indicating device 130, Figure 3B is an exploded view of the indicating device 130, Figure 3Cis a side view of the indicating device 130, Figure 3D is a top view of the indicating device 130 when installed on the housing 110. In addition, Figure 3D the circled part in also provides an enlarged view.

[0041] As Figures 3A - 3C shown, the indicating device 130 includes a mounting bracket 131 and a button spring piece 132. The button spring piece 132 is connected to the mounting bracket 131, and the mounting bracket 131 is mounted on the bottom surface of the base body 112 of the housing 110. The button spring piece 132 is in the shape of a hollow partial sphere and protrudes towards the control sleeve 220. The button spring piece 132 also includes several mounting feet 321 provided around it. The mounting bracket 131 includes a mounting bracket body 315 and mounting structures provided on opposite sides of the mounting bracket body 315. A pair of slots 316 for receiving the mounting feet 321 of the button spring piece 132 are provided on the mounting bracket body 315, and the button spring piece 132 is connected to the mounting bracket 131 by fitting its mounting feet 321 into the slots 316 of the mounting bracket 131.

[0042] The mounting bracket 131 is mounted to the housing 110 in a shape-matching manner and is mounted along the axial direction of the control sleeve 220. To avoid incorrect installation direction resulting in the button spring piece 132 protruding away from the control sleeve 220, the mounting structures provided on opposite sides of the mounting bracket body 315 are asymmetric with respect to the mounting bracket body 315. The first mounting structure on the first side of the mounting bracket 131 includes a mounting bracket protrusion 311, and the second mounting structure on the second side of the mounting bracket 131 includes a mounting bracket groove 312. They are respectively connected to the corresponding mounting structures on the housing 110 in a shape-matching manner to achieve the mounting of the mounting bracket 131 to the housing 110. Thus, by providing the asymmetric mounting structures, the operator can be guided to install the mounting bracket 131 in the housing 110 in the correct direction.

[0043] As Figure 3D shown, the housing 110 is provided with a housing groove 351 for receiving the mounting bracket protrusion 311 and a housing protrusion 352 for being received by the mounting bracket groove 312. Thus, the mounting bracket 131 can be mounted to the housing 110 in a shape-matching manner.

[0044] Figures 4A - 4C shows the relative positional relationship between the push-push motion mechanism 120 and the indicating device 130 when the actuating device 100 is in the first working state, the second working state, and the third working state respectively. To clearly show the control sleeve 220, Figures 4A - 4C the fixed sleeve 250 is hidden in.

[0045] As Figure 4A shown, in the first working state, the lid is with the actuating sleeve 10 (see Figure 2A) are in the open state together. The push rod 210 is in the position where it extends farthest from the housing 110. The control ring 230 is accordingly located at the lower end of the control sleeve 220. If the actuating sleeve 10 is now pushed onto the outer actuating end 211 of the push rod 210 together with the lid, the actuating projection 216 will engage in the actuating groove 15 and, in the case of subsequently further pressing the actuating sleeve 220 onto the outer actuating end 211 of the push rod 210, due to the helical course of the actuating groove 15, cause the push rod 210 to rotate by approximately 90°. During this rotational movement, the stop projection 215 of the push rod 210 rests on the annular stop surface 254 (see Figure 2B ) and is guided by it, thereby preventing the axial movement of the push rod 210 in the housing 110 caused by the actuating groove 15 during the rotation of the push rod 210. Only after the push rod 210 has been fully inserted into the actuating sleeve 220 and the actuating projection 216 has been received in the end receiving portion 16 of the actuating groove 15 can the push rod 210 be axially moved in the housing 110 by further pressing the lid. During this process, the stop projection 215 that previously rested on the stop surface 254 is guided along the inclined surface 256.

[0046] In Figure 4A In the first operating state shown, the push rod 210 has not moved axially downwards yet, and thus has not driven the control sleeve 220 downwards either. The projection 272 on the control sleeve 220 is at a certain distance from the indicating device 130.

[0047] As Figure 4B shown, in the second operating state, the lid is pressed into the housing 110, that is, the push rod 210 is pushed into the housing 110 to the maximum extent. The control projection 238 on the inner side of the control ring 230 and the push-push control surface on the outer side of the control sleeve 220 cooperate with each other. During the axial movement downwards of the push rod 210 into the housing 110, that is, in Figure 4A , the control projection 238 of the control ring 230 first engages with the first deflection surface 274, whereby the control ring 230 rotatably mounted in the housing can rotate relative to the control sleeve 220 firmly mounted and non-rotatable, and rotate to the right in Figure 4A until it reaches the position shown in Figure 4B .

[0048] In Figure 4BIn the second operating state shown, the push rod 210 is pressed into the housing 110 to the maximum extent, driving the control sleeve 220 to move downward to the maximum extent, so that the protrusion 272 on the control sleeve 220 contacts the indicating device 130 and presses the key spring piece 132 of the indicating device 130 to emit a sound. After the operator hears this sound feedback, it can be judged that the push rod 210 has been pressed into the housing 110 to the maximum extent, that is, it has been pressed in place. At this time, the operator can stop pushing the lid and instead release the lid.

[0049] If the lid is released after the push rod 210 has been pressed into the housing 110 to the maximum extent (as Figure 4B shown), due to the preloading force of the spring 240, the push rod 210 is pushed out of the housing 10 again a little, so the push rod completes an upward return stroke in Figure 4B and reaches Figure 4C the third operating state shown.

[0050] As Figure 4C shown, in the third operating state, the further rotated control protrusion 48 is engaged with the locking groove 276, so that the control sleeve 220 and thus the push rod 210 and the actuating sleeve 220 and the lid are locked in the Figure 4C position shown, and at this time the lid is in the closed state. The control protrusion 215 initially guided downward along the inclined surface 256 (see Figure 2B ) moves upward again approximately along the inclined surface 256 a little accordingly. In the Figure 4C third operating state shown, compared with Figure 4B , since the push rod 210 is pushed out of the housing 10 a little, it drives the control sleeve 220 to move upward as well, so that the protrusion 272 on the control sleeve 220 leaves the indicating device 130.

[0051] To open the lid again from the closed state, the operator can apply a thrust to the lid in Figure 4C so that the lid and the push rod 210 are pressed into the housing 110 to the maximum extent again. After that, the control protrusion 238 of the control ring 230 engages with the second deflection surface 278, and the ring is further rotated accordingly, so that the control protrusion 238 can move downward along the guiding surface 280 ( Figure 2A ), resulting in further rotation of the control ring 230 in this rotation direction and reaching Figure 4BThe state shown. In this state, when the operator releases the lid, the push rod 210 can be pressed back by the helical spring 240 to the position where it extends farthest from the housing 110. Due to the torsion that occurred during the previous rotation in the actuating sleeve 10, the spring 240 also causes the push rod 210 to rotate back in the actuating sleeve 10 along the actuating groove 15, so that the actuating sleeve 220 can be released from the push rod 210, allowing the lid to be opened.

[0052] Since the actuating device of the present disclosure is provided with an indicating device capable of providing sound feedback and cooperating with the push-push movement mechanism, when the operator pushes the lid to open or close the lid, it can remind the operator that the axial moving part of the push-push movement mechanism has been pressed into the housing to the maximum extent, that is, it has been pressed in place. At this time, the lid should be released to prevent problems caused by continuously pushing the lid, such as damaging components, etc.

[0053] As an indicating device for feedback sound, the key elastic sheet of the present disclosure can make it easy for the operator to obtain a prompt that the lid has been pressed in place because the key elastic sheet will emit a clear feedback sound when pressed.

[0054] The present disclosure also provides a lid assembly, which includes an actuating device according to the present disclosure and a lid not shown in the figure.
