Description

Technical Field

[0001] This invention relates to the field of automotive parts, and more particularly to a movable cover assembly and trim assembly. Background Technology

[0002] Some off-road vehicles have features around the rear side windows designed to accommodate luggage or ladders. These luggage or ladders need to be supported by the body panels at the vehicle's waistline. If there is a decorative trim strip (or bright strip) at the bottom of the rear side window's waistline, refer to... Figure 1 If so, an opening 011 needs to be provided for the trim strip 01 to allow the support structure 02 of the luggage bag or ladder to pass through the trim strip and support the sheet metal 03 at the waistline of the body.

[0003] The existing products are designed for models without luggage compartments or ladders, and the bright strips do not have openings. For example... Figure 1 As shown, for models equipped with luggage compartments and ladders, there are openings in the bright strip, allowing the luggage compartment or ladder support structure to penetrate into the bright strip and contact the sheet metal. The bright strip openings are covered with fixed cover plates.

[0004] However, this structure has the following shortcomings: (1) When using luggage or ladders, the cover plate needs to be removed from the bright strip. When not in use, the cover plate needs to be put back on. The cover plate is inconvenient to store.

[0005] (2) If the cover is fixed to the bright strip, the cover needs to be reversed outwards when it is opened, and the cover is completely exposed, which affects the matching space near the luggage and ladder fixing point.

[0006] (3) The product has multiple categories and the working conditions are not universal. It is divided into two types: open and closed. It also needs to be matched according to the vehicle model. Therefore, the luggage bag and ladder are assembled in place at the factory without the use of a cover plate. If the consumer wants to remove the luggage bag and ladder later, the cover plate is needed to cover the clearance hole. If the consumer's vehicle model does not have a luggage bag and ladder, the parts need to be replaced later if there is a need. It cannot meet the diversity and mobility of consumer needs.

Detailed Implementation

[0053] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0054] like Figures 2 to 22 As shown, this embodiment provides a movable cover plate assembly, which is installed on the opening 111 of the base member 1. The movable cover plate assembly includes: At least one first movable cover plate 2 is movably disposed on the base member 1 and has a first closed position that at least partially covers the opening 111 and a first open position that exposes the opening 111; when the first movable cover plate 2 is in the first open position, it is at least partially hidden inside the base member 1. At least one first reset drive 3 is connected between the first movable cover plate 2 and the base member 1, and can always apply a reset force to the first movable cover plate 2 to make the first movable cover plate 2 tend to the first open position; And at least one locking component 4, disposed on the base component 1; the locking component 4 includes a movable component (the movable component can move relative to the base component 1), and a mating part is provided on the first movable cover plate 2; when the first movable cover plate 2 is in the first closed position, the movable component can engage with the mating part, and the direction of the engagement on the movable component is opposite to the direction of the reset force; when the first movable cover plate 2 in the first closed position is pressed, the movable component can disengage from the engagement with the mating part, and the reset force can drive the first movable cover plate 2 to move to the first open position.

[0055] Specifically, in use, when the first movable cover 2 is in the first closed position, the movable part of the locking assembly 4 can engage with the mating part of the first movable cover 2 to overcome the reset force and keep the first movable cover 2 in the first closed position; when a pressing force is applied to the first movable cover 2 in the first closed position, the movable part of the locking assembly 4 can disengage from the mating part, and the reset force of the first reset drive 3 can drive the first movable cover 2 to automatically move to the first open position.

[0056] Therefore, the movable cover assembly of this application achieves simple operation of pressing to open and pressing to close. The first reset drive 3 continuously applies a reset force to the first movable cover 2 towards the open position, and the locking assembly 4 overcomes this reset force in the closed position to keep the cover closed. This achieves automatic opening and at least partial concealment within the base component 1 after pressing to unlock, eliminating the need for manual pushing, pulling, or disassembly of the cover. This simplifies operation, reduces the occupation of external space, and avoids the problem of cover loss. When applied to vehicle trim strips, the movable cover assembly of this application can be used in both perforated and non-perforated applications on all vehicle models, demonstrating strong versatility.

[0057] In the specific implementation method, refer to Figure 2 , Figure 3 and Figure 10 The movable part is a sliding part 41, which is slidably disposed on the base part 1, and the mating part is a guide and limiting structure 23.

[0058] The sliding member 41 can engage with the guide limiting structure 23 when the first movable cover plate 2 is in the first closed position. Through the engagement of the sliding member 41 with the guide limiting structure 23, the first movable cover plate 2 is reliably locked in the first closed position. The structure is simple and compact, and the locking is stable. It is especially suitable for small shielding devices.

[0059] Optionally, to facilitate the installation of the slider 41, refer to Figure 8 and Figure 9 The base component 1 is provided with a sliding groove 13. The sliding component 41 includes a sliding seat 411 and a sliding limiting post 412 connected to each other. The sliding seat 411 is slidably disposed in the sliding groove 13. The sliding limiting post 412 can extend through the opening 131 of the sliding groove 13 and can cooperate with the guide limiting structure 23.

[0060] By forming a groove 13 on the base component 1, space is saved and the smoothness of sliding is ensured, making it easier for the sliding limit post 412 to enter the track on the guide limit structure 23 more accurately.

[0061] The sliding seat 411 and the sliding limiting post 412 are fixed together and can be processed and fixed separately or integrally formed. The groove 13 is formed inside the base member 1 and located on one side of the opening 111. It is an elongated groove extending along the length of the base member 1. The base member 1 is generally formed by at least a top plate 11 and two side plates 12. The opening 111 is formed on the top plate 11, and the groove 13 is formed on the inner wall of one of the side plates 12. The opening 131 of the groove 13 also extends along the length of the base member 1 and faces the first movable cover plate 2, so that the sliding limiting post 412 can extend and selectively cooperate with the guide limiting structure 23 on the first movable cover plate 2.

[0062] The cross-sectional shape of the groove 13 can be designed according to requirements, for example, it can be designed according to... Figure 8 The cross-section shown is a right trapezoid, and the opening 131 of the slide groove 13 is correspondingly opened on the side of the right-angled trapezoid in the slide groove 13. The sliding seat 411 and the sliding limit post 412 can both be cylindrical structures with successively decreasing diameters and arranged coaxially, with their axes perpendicular to the length direction of the slide groove 13.

[0063] Further optionally, to facilitate automatic alignment of the slider 41, refer to Figure 10 The locking assembly 4 also includes two reset elastic members 42. One end of each reset elastic member 42 is disposed on both sides of the sliding member 41, and the other end is connected to the base member 1, for holding the sliding member 41 at a midpoint position O.

[0064] The reset elastic element 42 can be, for example, a spring, elastic rubber, or other elastic element, symmetrically arranged on both sides of the slider 41, with one end acting on the slider 41 and the other end fixed to the base component 1. When the slider 41 is pushed to the left or right by an external force, the reset elastic element 42 on one side is compressed, and the other side is stretched. After the external force disappears, the restoring force of the reset elastic element 42 will cause the slider 41 to return to the intermediate equilibrium position (i.e., the midpoint position O). This allows the slider 41 to automatically return to the midpoint position O when no external force is applied, providing a basis for cyclic locking and unlocking.

[0065] Taking a scenario where both reset elastic elements 42 are springs, the length of the slide groove 13 is placed horizontally, and the reset elastic elements 42 also extend horizontally, the two springs are denoted as the left limiting spring 421 and the right limiting spring 422, respectively. The reset principle of the sliding element 41 is as follows: Reference Figure 10 The sliding seat 411 is stably maintained at the midpoint position O by the left limiting spring 421 and the right limiting spring 422. Its movement direction V1 is constrained by the groove 13 of the base component 1. When the sliding limiting post 412 is subjected to force and moves to the left or right, the force is transmitted to the sliding seat 411 through the structure itself. The reset elastic member 42 is displaced to the left or right in the groove 13. When it moves to the left, the right limiting spring 422 generates a rightward reset force on it. When it moves to the right, the left limiting spring 421 generates a leftward reset force on it. Due to the elastic force of the left limiting spring 421 and the right limiting spring 422, once the force applied to the sliding limiting post 412 disappears, the sliding seat 411 returns to its original midpoint position O.

[0066] Further optional, refer to Figures 16 to 20A circular guide track 24 is formed on the guide limiting structure 23, and the slider 41 can move along the circular guide track 24. When the first movable cover 2 moves from the first open position to the first closed position, the slider 41 can slide within the circular guide track 24 to achieve the closing and locking of the first movable cover 2; when the first movable cover 2 is pressed again, the slider 41 can continue to slide within the circular guide track 24 and disengage from the guide limiting structure 23, and then return to the middle position O.

[0067] Optionally, refer to Figure 19 The circular guide rail 24 includes: A locking section 241 is used to guide the slider 41 to a locking position to engage the slider 41; A pressing section 242, which is connected to a locking section 241, is used to release the sliding member 41 from the locking position when the first movable cover plate 2, which is in the first closed position, is pressed, so that the sliding member 41 is disengaged. And a return segment 243, which is connected to the pressing segment 242 and the locking segment 241 respectively, is used to guide the slider 41 to return to the middle position O after release.

[0068] The circulating guide rail 24 can be a closed annular groove or a path composed of multiple protrusions and inclined surfaces. When the slider 41 contacts the circulating guide rail 24, it can move unidirectionally within it. The locking section 241 is responsible for ensuring that the slider 41 is smoothly introduced into the locking position during the manual closing of the first movable cover 2, so that it locks the first movable cover 2. The pressing section 242 is responsible for pushing the slider 41 out of the locking position when the user presses the closed first movable cover 2, and automatically returning it to the middle position O with the help of the reset elastic element 42, preparing for the automatic opening of the first movable cover 2. The return section 243 ensures that during the automatic opening of the first movable cover 2, the slider 41 can be pushed to the deviated position and finally return to the middle position O, completing a complete cycle and preparing for the next cycle. Through the cooperation of the circulating guide rail 24 with the slider 41, the reset elastic element 42 and the first reset drive element 3, the cyclic movement of the slider 41 is realized, realizing the functions of pressing to close and locking, and pressing to open. The structure is compact and the operation is reliable.

[0069] Furthermore, referring to Figure 19 The locking section 241 includes, in sequence: a first guide section 2411, for guiding the slider 41, which is located at the middle position O, to a first deviation position when the first movable cover 2 moves from the first open position to the first closed position; and a second guide section 2412 with a locking groove 24121 at one end, for guiding the slider 41 to the locking position by means of the reset elastic member 42 after the slider 41 reaches the first deviation position, so as to engage with the locking groove 24121.

[0070] The pressing section 242 includes, in sequence: a third guide section 2421, used to guide the slider 41, which is in the locked position, to a second deviated position when the first movable cover 2, which is in the first closed position, is pressed, so that the slider 41 is disengaged from the guide limiting structure 23; and a fourth guide section 2422, used to guide the slider 41 back to the middle position O by means of the reset elastic member 42 after the slider 41 reaches the second deviated position.

[0071] The return segment 243 includes, in sequence: a fifth guide segment 2431, used to guide the slider 41 to a third deviation position by means of the reset force of the first reset drive 3 when the slider 41 is in the middle position O and the first movable cover 2 moves from the first closed position to the first open position; and a sixth guide segment 2432, used to guide the slider 41 back to the middle position O by means of the action of the reset elastic member 42 after the slider 41 reaches the third deviation position.

[0072] More specifically, refer to Figure 3 and Figure 15 Typically, the first movable cover plate 2 includes a rectangular cover plate body 21, with a first mounting plate 22 vertically connected to the side of its bottom surface. The first side of the first mounting plate 22 is connected to the side of the cover plate body 21. The first mounting plate 22 is a long strip-shaped plate, and a guide limiting structure 23 protrudes from the outer wall of the first mounting plate 22 and is close to the first end of the first mounting plate 22. This first end is the end of the first mounting plate 22 that is far away from the reset force application point M of the first reset drive member 3.

[0073] Reference Figure 18 and Figure 20The guide limiting structure 23 includes a first guide block 231 and a second guide block 232 arranged at intervals opposite to each other. Together, they define a circular guide track 24 around the first guide block 231. The outer peripheral surface of the first guide block 231 includes a first inclined surface 2311, a first straight surface 2312, a second inclined surface 2313, an inwardly concave arc surface 2314, a third inclined surface 2315, a second straight surface 2316, a fourth inclined surface 2317, and a third straight surface 2318 connected in a circumferential sequence. These eight surfaces are all perpendicular to the surface of the first mounting plate 22. The first inclined surface 2311 is arranged near the second side of the first mounting plate 22, and the second straight surface 2316 is arranged near the first side of the first mounting plate 22. The first inclined surface 2311 is arranged according to the second side of the first mounting plate 22. The first straight surface 2312 is inclined towards the first side, and the wall of the first straight surface 2312 is perpendicular to the plate surface of the cover plate body 21. The second inclined surface 2313 is inclined towards the second end of the first mounting plate 22, moving away from the first side. The concave arc surface 2314 is an arc-shaped groove formed by the indentation towards the second end of the first mounting plate 22. The third inclined surface 2315 is inclined towards the first side, moving away from the first side. The wall of the second straight surface 2316 is parallel to the plate surface of the cover plate body 21. The fourth inclined surface 2317 is inclined towards the second end of the first mounting plate 22, moving away from the first side. The wall of the third straight surface 2318 is perpendicular to the plate surface of the cover plate body 21.

[0074] The outer surface of the second guide block 232 includes a fifth inclined surface 2321, a sixth inclined surface 2322, and a seventh inclined surface 2323 connected in sequence. The ends of the first inclined surface 2311 and the seventh inclined surface 2323 are respectively connected to the bottom surface of the cover plate body 21. All three inclined surfaces are perpendicular to the surface of the first mounting plate 22. The fifth inclined surface 2321 is arranged in an inclined direction from the first end of the first mounting plate 22 to the second end, gradually moving away from the first side. The sixth inclined surface 2322 is arranged in an inclined direction from the first end of the first mounting plate 22 to the second end, gradually moving away from the first side. The seventh inclined surface 2323 is arranged in an inclined direction from the second end of the first mounting plate 22 to the first end, gradually moving closer to the first side.

[0075] The portion of the first inclined surface 2311 near the first end of the first mounting plate 22, the area between the first mounting plate 22 and its second side, and the area between the first straight surface 2312 and the first end of the first mounting plate 22 constitute the first guide segment 2411. The area between the fifth and sixth inclined surfaces 2321 and the second inclined surface 2322 of the second guide block 232 and the second inclined surface 2313 of the first guide block 231, and the groove area where the concave arc surface 2314 is located constitutes the second guide segment 2412. The groove area where the concave arc surface 2314 is located constitutes the locking groove 24121. The area between the seventh inclined surface 2323 of the second guide block 232, the third inclined surface 2315 of the first guide block 231, and the bottom surface of the cover plate body 21 constitutes the third guide segment 2421. The area between the second straight surface 2316 and the bottom surface of the cover plate body 21 constitutes the fourth guide segment 2422. The region outside the fourth inclined surface 2317 and the region outside the third inclined surface 2315 constitute the fifth guide segment 2431 described above. The region between the portion of the first inclined surface 2311 near the second end of the first mounting plate 22 and the second side of the first mounting plate 22 constitutes the sixth guide segment 2432 described above. The length of the portion of the first inclined surface 2311 near the second end of the first mounting plate 22 should be less than the length of the portion of the first inclined surface 2311 near the first end of the first mounting plate 22, and the boundary between the two corresponds exactly to the median position O when the first movable cover 2 is in its closed position.

[0076] Taking the slide 13 as horizontally placed along its length and the first movable cover 2 as horizontal when its surface is in its closed position as an example, according to Figure 16 The orientation shown in the figure indicates that, during use, the movement path of the sliding limit post 412 in the open and closed state of the first movable cover plate 2 is as follows (the reciprocating movement path S1 of the sliding limit post 412 in the slide groove 13, and the movement path S2 of the sliding limit post 412 relative to the first movable cover plate 2 can be referred to). Figure 16 (arrow in the middle) When no force is applied, the sliding limit post 412 is stably in the first position A (i.e., the median position O).

[0077] When the first movable cover 2 changes from the open position to the closed position, i.e., pushes the first movable cover 2, and applies a force value to make the first movable cover 2 move from top to bottom along the movement direction V2. The aforementioned dividing position in the first inclined surface 2311 of the first guide block 231 will contact the sliding limit post 412. At this time, the sliding limit post 412 is affected by the stable leftward pushing force applied by the first inclined surface 2311 of the first guide block 231, and moves to the left in the slide groove 13 of the base component 1. Relative to the position of the first movable cover 2, the path of the sliding limit post 412 is from the first position A to the second position B. When the second position B is reached, that is, the sliding limit post 412 moves to the leftmost position in the slide groove 13 (which also corresponds to the first deviation position mentioned above). At this time, the sliding limit post 412 is located in the area between the first straight surface 2312 and the first end of the first mounting plate 22. The leftward pushing force disappears, and the sliding seat 411 is automatically reset to the middle position O along the second inclined surface 2313 of the first guide block 231 by the right limit spring 422. However, it is hooked by the locking groove 24121 of the first guide block 231 and stays in the third position C, forming a stable engagement with the locking groove 24121. At this time, the first movable cover plate 2 is released without applying force. The first movable cover plate 2 is then subjected to the downward reset force at the tail (that is, the reset force applied by the first reset drive member 3 to the second end of the first mounting plate 22), causing the first movable cover plate 2 to have a tendency to move upward in the direction V3. However, it is restricted by the sliding limit post 412, and the first movable cover plate 2 is in the closed position, remaining stationary and stably closed.

[0078] When the first movable cover 2 changes from the closed position to the open position, press the first movable cover 2 down a short distance first, and apply a force value to make the first movable cover 2 move from top to bottom along the movement direction V4. At this time, the sliding limit post 412 is affected by the third inclined surface 2315 of the first guide block 231, and pushes out the sliding limit post 412 hooked in the third position C. At this time, the sliding limit post 412 is subjected to a force to the left and moves to the fourth position D (that is, the second deviation position mentioned above). At this time, the pushing force to the left disappears, and the sliding seat 411 is restored to the middle value position O by the right limit spring 422 to the right, that is, in the fifth position E. However, when the first movable cover plate 2 is released without applying force, the first movable cover plate 2 is subjected to a downward reset force at its tail, causing the first movable cover plate 2 to tend to move upward in the direction V3. Subsequently, the sliding limit post 412 is pushed to the right by the fourth inclined surface 2317 of the first guide block 231 and moves to the sixth position F, that is, the sliding limit post 412 moves to the rightmost position in the slide groove 13 (which also corresponds to the third deviation position mentioned above). After that, the first movable cover plate 2 separates from the sliding limit post 412, the first movable cover plate 2 opens, the rightward force of the sliding limit post 412 disappears, and the sliding limit post 412 is reset to the left to the middle position O by the left limit spring 421, that is, returns to the first position A.

[0079] The above describes the movement path of the sliding limit post 412 during the opening and closing process of the first movable cover 2. During this process, the sliding limit post 412 moves cyclically relative to the first movable cover 2 in the first position A, the second position B, the third position C, the fourth position D, the fifth position E, and the sixth position F. The above process can be repeated when closing and opening the first movable cover 2.

[0080] Further optional, refer to Figure 17 Along the length direction of the first movable cover plate 2 (i.e., the length direction of the first mounting plate 22): There should be a length L1 between the connection point between the second straight surface 2316 and the fourth inclined surface 2317 and the boundary position of the corresponding median position O, so as to ensure that when the sliding limit post 412 reaches the fifth position E, the center of the sliding limit post 412 corresponds to the fourth inclined surface 2317. Preferably, L1 > radius R of the sliding limit post 412, so as to ensure that the sliding limit post 412 has a certain distance to bounce back to the median position O and can be smoothly guided downward.

[0081] The groove width L2 of the concave arc surface 2314 along the length direction of the first movable cover plate 2 is greater than 1 / 2R, so as to ensure that the sliding limit post 412 can be stuck in the locking groove 24121 and will not pop up directly.

[0082] The distance L3 between the endpoints of the first straight surface 2312 and the fifth inclined surface 2321 that are far from the sixth inclined surface 2322 is greater than 2R, so as to ensure the effective guide length of the sliding limit post 412.

[0083] The distance L4 > R between the connection points of the first straight surface 2312 and the fifth inclined surface 2321 and the sixth inclined surface 2322, so as to ensure that the sliding limit post 412 can smoothly enter the locking groove 24121 along the guide trend.

[0084] The distance L5 > 2R between the connection point of the sixth inclined plane 2322 and the seventh inclined plane 2323 and the connection point of the third inclined plane 2315 and the second straight plane 2316, so as to ensure that the sliding limit post 412 can pop up smoothly.

[0085] The projection length L6 of the first inclined surface 2311 in the length direction of the first movable cover plate 2 is greater than L1+L2+L4+L5+2R, so as to ensure that there is sufficient guiding length to the right for the sliding limit post 412.

[0086] Further optional, refer to Figure 18 The angle α1 between the first inclined surface 2311 and the length direction of the first movable cover plate 2 is greater than 10°, so that the first movable cover plate 2 can push the sliding limit post 412 forward when pressed.

[0087] The angle α2 between the second inclined surface 2313 and the length direction of the first movable cover plate 2 is greater than 0°, so as to form a downward guiding trend, so that the sliding limit post 412 can only bounce back to the right and cannot move to the left.

[0088] The angle α3 between the fifth inclined surface 2321 and the length direction of the first movable cover plate 2 is α3 > α2 + 30°, forming a trumpet shape with α2, which guides the rightward rebound of the sliding limit post 412.

[0089] The angle α4 between the seventh inclined plane 2323 and the thickness direction of the first movable cover plate 2 is greater than 5°, which guides the upward movement of the sliding limit post 412.

[0090] The angle α5 between the fourth inclined surface 2317 and the thickness direction of the first movable cover plate 2 is greater than 30°, which guides the downward movement of the sliding limit post 412.

[0091] Alternatively, the first reset drive 3 can be implemented as follows: (Refer to...) Figure 2 and Figure 21 The first reset drive component 3 includes two first reset structures 30 symmetrically arranged on both sides of the first movable cover plate 2. Each first reset structure 30 includes a first support base 31, a first support block 32, and a first reset elastic element 33. The first support block 32 is disposed on the first support base 31. Two first reset sliding grooves 221 are symmetrically arranged on both sides of the first movable cover plate 2. The first support block 32 can be slidably inserted into the corresponding first reset sliding groove 221. One end of the first reset elastic element 33 is connected to the first support base 31, and the other end is connected to the first movable cover plate 2. The first support block 32 forms a lever fulcrum. The first reset elastic element 33 can drive the first movable cover plate 2 to rotate around the first support block 32 through the first reset sliding groove 221, so as to drive the first movable cover plate 2 to move to the first open position when the locking component 4 is disengaged.

[0092] The first support block 32 and the first reset sliding groove 221 form the fulcrum and lever in the lever. The reset force direction V5 and the limiting direction V6 of the sliding limit post 412 respectively form the forces at both ends of the lever. When the first movable cover plate 2 moves to the closed position and engages at the third position C, and when the first movable cover plate 2 moves to the open position and engages at the fifth position E, the first movable cover plate 2 is released without force. The reset force of the first reset elastic element 33 on the first movable cover plate 2 and the first support block 32 engaged in the first reset sliding groove 221 form a lever effect. In this lever-type reset structure, the force of the reset elastic element 42 drives the first movable cover plate 2 to rotate around the first support block 32, which can generate a large opening torque and the movement is smooth.

[0093] It can be understood that each first movable cover plate 2 corresponds to one first reset drive component 3, and each first reset drive component 3 includes two symmetrical first reset structures 30. Two first mounting plates 22 are symmetrically arranged on both sides of the bottom surface of the cover plate body 21 of the first movable cover plate 2. Two first reset sliding grooves 221 are opened on the two first mounting plates 22. The length direction of the first reset sliding grooves 221 extends along the length of the first mounting plate 22. The first support block 32 can be, for example, a cylindrical block and is vertically inserted into the first reset sliding groove 221. The first support block 32 is fixed to the first support seat 31 (for example, integrally formed). The other end of the first reset elastic member 33 is connected to the second end of the first mounting plate 22 of the first movable cover plate 2, and the connection point constitutes the reset force application point M. The first support seat 31 is fixed relative to the base component 1. It can be directly fixed to the base component 1 in any feasible way. Alternatively, the first support seat 31 can be fixed to other components outside the base component 1. For example, when the base component 1 is a trim strip on a vehicle, the bottom of the first support seat 31 can be directly fixed to the sheet metal of the vehicle in any feasible way.

[0094] Specifically, the working principle of the first reset drive 3 is as follows: Reference Figure 21 and Figure 22 When the first movable cover plate 2 is closed, the first movable cover plate 2 is located in the closed position P1, and the first reset elastic element 33 is in the stretched state. At this time, the reset force is generated on the first movable cover plate 2 in the reset force direction V5 through the reset force application point M. The sliding limit post 412 limits the movement of the first movable cover plate 2 at the other end of the lever, so that the first movable cover plate 2 is stably in the closed state.

[0095] When the first movable cover 2 needs to be opened, force needs to be applied to the first movable cover 2 in the pressing direction V7 (this pressing direction V7 also corresponds to the above-mentioned movement direction V4), so that the sliding limit post 412 slides out of the locking groove 24121 of the guide limit structure 23 from the third position C to the fourth position D. At this time, the first reset elastic member 33 is in a further stretched state, and the reset force generated on the first movable cover 2 is further increased. The sliding limit post 412 has slid out of the locking groove 24121. The sliding limit post 412 is affected by the right limit spring 422 in the slide groove 13 and has a reset force to the right, so that the sliding limit post 412 moves to the middle position O (that is, corresponding to the above-mentioned fifth position E). At this time, the first movable cover 2 is in the cover pressing position P2. At this time, the limiting effect of the sliding limit post 412 in the limiting direction V6 disappears. When the pressing force is released, the first movable cover 2 can return to its position under the reset force of the first reset elastic member 33. The first reset elastic member 33 reaches Figure 22 The contracted state of the first movable cover plate 2 is stably positioned in the open position P3.

[0096] When the first movable cover plate 2 needs to be closed again, a force is applied to the first movable cover plate 2 in the closing direction V8 (which also corresponds to the movement direction V2 mentioned above), pushing the first movable cover plate 2 to the closed position. The sliding limit post 412 slides into the locking groove 24121, which plays a limiting role. Together with the reset force of the first reset elastic member 33, the first movable cover plate 2 is in a stable closed state.

[0097] Further optional, refer to Figure 9 as well as Figures 11 to 14 The side wall of the slide groove 13 is provided with an insertion port 134; the locking assembly 4 also includes a fixing buckle 43, which can be inserted into the slide groove 13 through the insertion port 134 and locked with the slide groove 13. The other end of the reset elastic member 42 is connected to the base member 1 through the fixing buckle 43.

[0098] The fixing buckle 43 adopts an insert-type snap-fit, which is easy to install without welding or bonding. It is especially suitable for assembly in small spaces such as inside the slide 13, reducing the assembly difficulty and ensuring the stability of the connection.

[0099] It is understood that each locking component 4 includes a sliding member 41, two reset elastic members 42, and two fixing buckles 43. The number of locking components 4 is the same as the number of guide limiting structures 23 on the first movable cover plate 2. Preferably, one guide limiting structure 23 is installed on one first movable cover plate 2, and one locking component 4 is correspondingly engaged with it. Optionally, two guide limiting structures 23 are installed on one first movable cover plate 2, symmetrically installed on the two first mounting plates 22 of the first movable cover plate 2, and two locking components 4 are correspondingly engaged with them.

[0100] Optionally, to facilitate the snap-fit ​​fixing of the buckle 43, the buckle 43 includes a buckle body 431 and a limiting block 432 disposed on the side of the buckle body 431. The insertion port 134 includes a side opening 1341 communicating with the slide groove 13. The side opening 1341 and the opening 131 of the slide groove 13 are located on the same side. The two side walls of the buckle body 431 can cooperate with the hole wall of the side opening 1341 to limit the buckle 43 in the length direction of the slide groove 13. The limiting block 432 can extend into the opening 131 of the slide groove 13 and cooperate with the hole wall of the opening 131 of the slide groove 13 to limit the buckle 43 in the height direction of the slide groove 13.

[0101] Alternatively, the fixing buckle 43 may further include an elastic piece 433 disposed on the side of the buckle body 431. The elastic piece 433 can be squeezed into the slide groove 13 through the opening 131 of the slide groove 13 and abut against the groove wall of the slide groove 13 to limit the fixing buckle 43 in the width direction of the slide groove 13.

[0102] The aforementioned buckle body 431 can be, for example, a rectangular block or... Figure 12The block shown has a right-angled trapezoidal cross-section, and its dimensions match the dimensions of the side opening 1341; the limiting block 432 is a long rectangular block, and its dimensions match the dimensions of the opening 131 of the slide groove 13. Each fixing buckle 43 may include one limiting block 432, or may include two limiting blocks 432.

[0103] Preferably, two limiting blocks 432 are symmetrically provided on both sides of the buckle body 431 for greater stability. For example, during installation, after aligning the buckle body 431 of the fixing buckle 43 with the side opening 1341 and the two limiting blocks 432 with the opening 131 of the slide groove 13, the elastic piece 433 deforms under pressure and enters the slide groove 13, abutting against the groove wall. The two sides of the buckle body 431 along the length of the slide groove 13 form an X-direction limiting structure 4311, which mutually constrains the wall of the side opening 1341, limiting the fixing buckle 43 along the length of the slide groove 13. At least a portion of the limiting block 432 remains within the opening 131, and the two sides of the limiting block 432 along the height of the slide groove 13 form a Z-direction limiting structure 4321, which mutually constrains the wall of the opening 131 of the slide groove 13, limiting the fixing buckle 43 along the height of the slide groove 13. The end of the elastic sheet 433 near the guide block forms a Y-direction limiting structure 4331, which can abut against the groove wall of the slide groove 13 on the side with the opening 131. It restrains the groove wall of the slide groove 13 to limit the fixed buckle 43 in the width direction of the slide groove 13 and prevent the fixed buckle 43 from coming out of the side opening 1341.

[0104] Alternatively, due to the presence of the Z-direction limiting structure 4321, the insertion port 134 may also include a bottom port 1342 that communicates with the side port 1341. The bottom port 1342 is opened at the bottom of the slide groove 13, specifically corresponding to the bottom edge of the right-angled trapezoidal section of the slide groove 13. The bottom of the buckle body 431 can partially extend out of the bottom port 1342.

[0105] Through the cooperation of the X-direction limiting structure 4311, Y-direction limiting structure 4331 and Z-direction limiting structure 4321, the fixed buckle 43 is stably and reliably fixed. The fixed installation of the fixed buckle 43 also enables the left limiting spring 421 and the right limiting spring 422 to stably provide the reset force, ensuring that the sliding member 41 always tends to reset to the midpoint position O.

[0106] Alternatively, the fixing buckle 43 may further include a mounting block 434 disposed on the side of the buckle body 431, and the elastic piece 433 is connected to the mounting block 434.

[0107] The mounting block 434 is fixed to one side of the fixing buckle 43, serving as a base for the elastic piece 433 and making the position of the elastic piece 433 more stable. The number of limiting blocks 432, mounting blocks 434, and elastic pieces 433 are equal. One end of the elastic piece 433 is fixed to the mounting block 434, and the other end can abut against the wall of the slide groove 13 after entering it. A gap is left between the side of the elastic piece 433 and the side wall of the buckle body 431. The elastic piece 433 itself has a certain elasticity. During the insertion of the fixing buckle 43 into the slide groove 13, the elastic piece 433 is deformed by the edge of the opening 131. After entering the slide groove 13, the elastic piece 433 recovers and abuts against the groove wall, thereby eliminating the gap and preventing the fixing buckle 43 from wobbling in the width direction. The elastic piece 433 can be a thin sheet integrally injection molded with the mounting block 434, limiting block 432, and buckle body 431, or it can be a separate metal spring.

[0108] Alternatively, the elastic sheet 433 is arranged at an angle from the mounting block 434 toward the limiting block 432 in a direction away from the cover plate body 21, that is, according to... Figure 12 The direction shown in the image is tilted downwards, which makes installation easier.

[0109] Alternatively, the fixing buckle 43 may further include a connecting block 435 connected between the limiting block 432 and the mounting block 434 to connect the limiting block 432 and the mounting block 434 into one unit, thereby improving the overall rigidity and deformation resistance of the fixing buckle 43.

[0110] It should be noted that the phrase "at least partially covered" in the text covers both cases where a single cover completely covers the opening 111 and cases where multiple cover plates jointly cover the opening 111; "at least partially hidden" covers cases where one end of the cover is hidden and the other end is exposed after the cover is opened (e.g., Figure 6 (as shown in the image).

[0111] In actual products, at least one opening 111 can typically be formed on a base component 1. For a single opening 111, one or more first movable cover plates 2 can be configured according to the size of the opening 111 and the usage requirements. When there is only one first movable cover plate 2, it alone covers the opening 111; when there are two or more first movable cover plates 2, each first movable cover plate 2 together covers the opening 111, with each first movable cover plate 2 covering a portion of the opening 111. The specific number of first movable cover plates 2 corresponding to a single opening 111 can be designed as needed. For example, in an optional embodiment, a single opening 111 corresponds to two first movable cover plates 2, and the two first movable cover plates 2 together cover the opening 111. The two first movable cover plates 2 can be the same or different in size. Each of the two first movable cover plates 2 has its own locking component 4 and first reset drive component 3, which are independently controlled, making opening and closing more flexible. Moreover, compared with only one first movable cover plate 2, the two first movable cover plates 2 expose less of the opening 111 when in the open position, thus occupying less external space.

[0112] Further optional, refer to Figures 2 to 7 The movable cover assembly also includes at least one second movable cover 5, which is movably disposed on the base member 1 and has a second closed position that at least partially covers the opening 111 and a second open position that exposes the opening 111; the second movable cover 5 is provided with a fixing limiting part 53; when the second movable cover 5 is in the second open position, it is at least partially hidden inside the base member 1; when both the first movable cover 2 and the second movable cover 5 are in their respective closed positions, at least a portion of the first movable cover 2 can be stacked on the fixing limiting part 53 of the corresponding second movable cover 5 to restrict the movement of the second movable cover 5.

[0113] In practical design, a single opening 111 can be fitted with only one first movable cover plate 2, or it can be fitted with both one first movable cover plate 2 and one second movable cover plate 5 simultaneously. For schemes with both first movable cover plates 2 and second movable cover plates 5, the number of second movable cover plates 5 can be one or more. The first movable cover plates 2 can restrict the movement of the second movable cover plates 5 by overlapping, but the overlapping relationship can be one first movable cover plate 2 overlapping one second movable cover plate 5, one first movable cover plate 2 simultaneously overlapping multiple second movable cover plates 5, or multiple first movable cover plates 2 each overlapping a corresponding second movable cover plate 5. Regardless of the combination of quantities, mutual restraint can be achieved as long as "at least a portion of the first movable cover plate 2 overlaps the corresponding fixed limiting part 53 of the second movable cover plate 5"; the specific choice can be made reasonably according to actual needs.

[0114] For example, in an optional embodiment, a single opening 111 corresponds to a first movable cover plate 2 and a second movable cover plate 5, the first movable cover plate 2 and the second movable cover plate 5 together shielding the opening 111, such as... Figure 3 As shown, compared to setting only one first movable cover 2, the scheme with two first movable cover 2 exposes less of the opening 111 when in the open position, thus occupying less external space; moreover, compared to setting two first movable cover 2, the second movable cover 5 in this scheme does not need to be equipped with a corresponding locking component 4, and its movement is restricted by the stacking of the first movable cover 2, making the structure more simplified.

[0115] Furthermore, referring to Figure 2 In the embodiment with a second movable cover plate 5, the movable cover plate assembly further includes at least one second reset drive member 6. The second reset drive member 6 is connected between the second movable cover plate 5 and the base member 1, and can always apply a reset force to the second movable cover plate 5 to move it toward the second open position. When the first movable cover plate 2 no longer presses against the second movable cover plate 5, the second reset drive member 6 will automatically push the second movable cover plate 5 to the open position.

[0116] Optionally, the second reset drive member 6 includes two second reset structures 60 symmetrically arranged on both sides of the second movable cover plate 5. Each second reset structure 60 includes a second support base 61, a second support block 62, and a second reset elastic member 63. The second support block 62 is disposed on the second support base 61. Two second reset sliding grooves 521 are symmetrically arranged on both sides of the second movable cover plate 5. The second support block 62 can be slidably inserted into the corresponding second reset sliding groove 521. One end of the second reset elastic member 63 is connected to the second support base 61, and the other end is connected to the second movable cover plate 5. The second support block 62 forms a lever fulcrum. The second reset elastic member 63 can drive the second movable cover plate 5 to rotate around the second support block 62 through the second reset sliding groove 521, so as to drive the second movable cover plate 5 to move to the second open position when the first movable cover plate 2 leaves the fixed limiting part 53.

[0117] Each second movable cover plate 5 corresponds to a second reset drive member 6. Each second reset drive member 6 includes two symmetrical second reset structures 60. The second movable cover plate 5 also includes a cover plate body 51 and two second mounting plates 52 symmetrically arranged on both sides of the bottom surface of the cover plate body 51. Two second reset sliding grooves 521 are opened on the two second mounting plates 52. The other end of the second reset elastic member 63 is connected to the end of the second mounting plate 52 of the second movable cover plate 5, and the connection point constitutes the reset force application point N. The second support base 61 is fixed relative to the base member 1. It can be directly fixed to the base member 1 in any feasible way, or the second support base 61 can be fixed to other parts outside the base member 1. The shape and structure of the second movable cover plate 5, and the structure and working principle of the second reset drive member 6 are basically the same as those of the first movable cover plate 2 and the first reset drive member 3 mentioned above. The only difference is that the second mounting plate 52 of the second movable cover plate 5 does not have a guide limiting structure 23, and a fixing limiting part 53 is added. It will not be described in detail here.

[0118] The first reset elastic element 33 and the second reset elastic element 63 can be, for example, reset springs, or other elastic components. Of course, depending on the needs, the first reset drive element 3 and the second reset drive element 6 can also adopt other automatically retractable structures; this embodiment is merely illustrative.

[0119] Alternatively, the fixing and limiting part 53 is a block structure, fixed to the bottom surface of the cover plate body 51 of the second movable cover plate 5 away from the second reset drive member 6. Part of the fixing and limiting part 53 extends out of the end of the second movable cover plate 5. The bottom surface of the fixing and limiting part 53 facing away from the second movable cover plate 5 has a guide inclined surface 531, so that the thickness of the guide and limiting part gradually decreases towards the outside of the end of the cover plate along the thickness direction of the second movable cover plate 5.

[0120] More specifically, taking the example of setting a first movable cover plate 2 and a second movable cover plate 5 at the opening 111, and placing the slide groove 13 horizontally along its length, the principle of the two cover plates achieving closure is as follows: like Figure 3 As shown, the first movable cover plate 2 is continuously subjected to a downward (i.e., corresponding to the reset force direction V5) reset force from the reset force application point M, which forms a lever effect with the first support block 32 stuck in the first reset sliding groove 221, giving it a tendency to move in the cover plate movement direction V9 (also corresponding to the aforementioned limiting direction V6). Through the sliding limiting post 412, the guide limiting structure 23 of the first movable cover plate 2 is limited, preventing the first movable cover plate 2 from moving in the cover plate movement direction V9, thus achieving a constraint closure effect.

[0121] At the same time, the second movable cover plate 5 is continuously subjected to a downward (corresponding to the reset force direction V10) reset force from the reset force application point N, forming a lever effect with the second support block 62 stuck in the second reset sliding groove 521, giving it a tendency to move in the cover plate moving direction V11. The fixed limiting part 53 of the second movable cover plate 5 presses it under the first movable cover plate 2. When the first movable cover plate 2 is restricted from moving, the second movable cover plate 5 is also restricted.

[0122] When the first movable cover 2 is opened, the second movable cover 5 will also automatically open under the action of the second reset drive 6. When both are in the open position, Figure 6 As shown. When in the open position, the movement of the left and right side covers is constrained by the length of their respective reset sliding grooves and the position of the support blocks.

[0123] Furthermore, the present invention also provides a trim assembly, comprising: Base component 1, which is the body of the decorative strip; And the aforementioned movable cover assembly.

[0124] The trim assembly includes the aforementioned movable cover plate assembly, which has the same effect and will not be described again here.

[0125] Furthermore, the aforementioned base component 1 can be any component that requires through holes and is desired to be concealed, such as vehicle exterior or interior trim parts, or other exterior or interior trim parts. More specifically, exterior trim parts include, but are not limited to, rear side window waistline trim strips or roof rack foot pedals. This application enables these openings 111 to be aesthetically concealed when not in use, and the cover can be opened and hidden simply by pressing when in use, greatly improving user convenience and product quality.

[0126] The solution in this application is particularly applicable to base component 1 being a waistline trim strip for the rear side window of a vehicle. Figure 6The diagram also shows the case where the base component 1 is a trim strip. The opening 111 is for the support structure of a luggage bag or ladder to pass through. Utilizing the structure of this application, the cover plate can be hidden inside the bright strip when opened, reducing the portion of the cover plate exposed outside the bright strip's surface and not affecting the matching space around the clearance hole. Integrating the cover plate onto the trim strip eliminates the need for disassembly and removal; the cover plate does not need to be removed from the bright strip, and it is structurally connected to the bright strip during both opening and closing, eliminating the risk of loss due to improper storage. Simultaneously, the guide function of the groove in the bright strip's own structure is fully utilized, and the locking component 4 is combined to cooperate with the closing of the cover plate, simplifying the opening and closing method. When the cover plate is open, sufficient space is provided, not affecting the use of the trim strip's opening structure by the hand component. When not in use, the cover plate is closed, providing both concealment and decorative effects for the bright strip's clearance hole. This trim strip assembly can be used in both open and closed usage conditions for all vehicle models, and the product is pre-assembled at the factory, meeting the diverse and flexible needs of consumers.

[0127] The above are merely illustrative embodiments of the present invention and are not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
