Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile manufacturing, and in particular to a sun visor mirror cover opening and closing structure, a sun visor assembly and a vehicle. BACKGROUND

[0002] With the rapid development of the automobile industry and the continuous improvement of the consumption level, the automobile has changed from a simple means of transportation to an important carrier integrating comfort, aesthetics and functionality. Under this trend, the market has put forward increasingly strict requirements on the quality, design and user experience of automobile interior and exterior parts. As a key component of the automobile interior, the function of the sun visor is no longer limited to blocking sunlight, but also serves to enhance the aesthetics of the vehicle interior environment and meet the daily use needs of users. At present, most sun visors are equipped with a vanity mirror to allow the driver or passenger to adjust their appearance when needed.

[0003] In order to protect the surface of the vanity mirror from being scratched, contaminated or damaged in a non-use state, a mirror cover that can be opened and closed is usually provided outside the vanity mirror. According to the material, the vanity mirror cover is mainly divided into two types: hard and soft. The hard mirror cover is usually made of plastic particles by injection molding process, which has good rigidity. The soft mirror cover is often made of cloth or thin plastic skin, which has a soft texture. The opening mode that matches the material of the mirror cover mainly exists in three mainstream designs in the current market: flip cover, sliding cover and magnetic attraction. Their costs and technical complexities increase in turn.

[0004] The flip cover sun visor is a widely used structure. The mirror cover is usually connected to the sun visor body through a rotating shaft or a hinge, and is opened by flipping along the fixed shaft when in use. The advantage of this scheme is that the structure is simple, the manufacturing cost is low, and the vanity mirror can be arranged centrally, which meets the symmetry aesthetics. However, the flip cover design has obvious defects: first, the opening angle of the mirror cover is usually limited, which limits the visual range when in use and easily causes a sense of oppression; second, the opening and closing of the mirror cover relies on physical buckles or friction positioning, which has a harsh operation feel and poor overall texture, making it difficult to meet the user's expectations for high-quality interior.

[0005] The sliding cover sun visor uses a mirror cover that slides along a specific track to open. The advantage is that the mirror cover can be completely removed from the field of view, providing a sense of no obstruction when in use and being easy to operate. However, this structure also has disadvantages: after the mirror cover is slid open, it occupies a large amount of additional space, the vanity mirror cannot be arranged centrally, affecting the overall aesthetics of the sun visor; at the same time, the sliding space occupies a large amount of space, reducing the actual usable area of the vanity mirror and its practicality.

[0006] Magnetic sun visor is a kind of high-end design scheme in recent years, through the magnet adsorption to realize the fixed and open and close of the mirror cover. Its advantages are outstanding: the mirror cover is convenient to open and close, and can completely separate from the visual area, the user experience is better; the vanity mirror can be designed in the center and realize the maximum area, improve the use convenience; the overall structure is relatively simple, which helps to reduce the thickness of the sun visor, improve the interior texture and user satisfaction. However, the magnetic scheme also has significant disadvantages: first, the magnet and the matching structure increase the material and manufacturing cost; second, the magnetic assembly often brings weight increase, which affects the lightness of the sun visor operation; more importantly, during vehicle driving, especially on bumpy road, the magnetic mirror cover may be accidentally detached due to insufficient adsorption force or vibration, resulting in swinging or impact, which has potential safety risks.

[0007] In summary, the several mainstream schemes of the existing sun visor vanity mirror cover all have their own limitations: the flip cover type has low cost, but the experience is depressing and the texture is insufficient; the sliding cover type has no visual obstruction, but occupies a large additional space after being opened and the mirror surface is small; the magnetic type has superior experience, but has high cost, large weight and the risk of mirror cover swinging during driving.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application, but the present application can also be implemented in other manners different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0027] Embodiment one As shown in the drawings, a sun visor mirror cover opening and closing structure for a vehicle includes a support part, a floating drive assembly and a lock sleeve 200, which is used to drive the soft cosmetic mirror cover to be rolled open or unfolded closed. Figures 1-5 The support part is fixedly arranged and fixed on the sun visor body after assembly, providing a reference for the installation of the floating drive assembly. The floating drive assembly is the power input and transmission core of the entire structure, which is elastically supported by the support part. The floating drive assembly is installed by an elastic support mode, so that it has a vertical floating stroke. This elastic support design provides a reset basis for subsequent pressing operation, and at the same time avoids the problem of rigid connection operation.

[0028]

[0029] ​The floating drive assembly comprises an operation part, a transmission part and a locking part. The operation part, as a part directly contacted by the user, is designed as a structure that can be pressed down, providing the user with a convenient triggering method, replacing the traditional flip type of picking, slide type of pulling and magnetic type of direct pulling, and improving the intuitiveness of operation. The transmission part is arranged in linkage with the operation part. The core function of the transmission part is to convert the vertical pressing motion of the operation part into the power for rolling up or unfolding the soft cosmetic mirror cover, realizing the conversion of motion form and ensuring the precise cooperation between the user operation and the mirror cover action. The locking part is arranged in linkage with the operation part and performs the lifting action synchronously with the operation part. The locking part is provided with a lock core 133. The lock core 133 is a key structure for realizing the position locking of the cosmetic mirror cover. Through the cooperation between the lock core 133 and the lock sleeve 200, the cosmetic mirror cover can be stably fixed after being opened or closed, avoiding accidental movement during driving.

[0030] The lock sleeve 200, as a core part for locking and guiding, is rotatably arranged on the sun visor body through bearings after assembly. The axis of the lock sleeve 200 is vertically arranged. This installation posture matches the vertical floating stroke of the floating drive assembly, ensuring the smoothness of motion transmission. A guide slide 210 is arranged on the side wall of the lock sleeve 200. The guide slide 210 is arranged in a ring around the lock sleeve 200, forming a continuous closed motion path and providing a complete motion track for the lock core 133. It should be noted that the guide slide 210 divides the lock sleeve 200 into two independent upper and lower sleeve pieces. The two sleeve pieces are connected together through an externally arranged connecting arm to ensure the coaxiality of the two sleeve pieces. The arrangement of the connecting arm will not hinder the motion of the lock core 133. The lock core 133 of the locking part in the floating drive assembly is located in the guide slide 210 and can freely slide along the guide slide 210. The path design of the guide slide 210 directly determines the motion law of the lock core 133. The guide slide 210 is provided with a first locking position for locking the lock core 133 after the cosmetic mirror is opened and a second locking position for locking the lock core 133 after the cosmetic mirror cover is closed, thereby controlling the switching of the opening and closing states of the mirror cover.

[0031] Specifically, in response to the first pressing operation on the operation part, the floating drive assembly moves downward, rolls up the soft cosmetic mirror cover through the transmission part, so that the cosmetic mirror cover is opened and the cosmetic mirror is completely exposed. At the same time, the lock core 133 moves to the first locking position along the guide slide 210 and is locked. In response to the second pressing operation on the operation part, the floating drive assembly moves downward again and then elastically resets upward. The cosmetic mirror cover is unfolded through the transmission part, so that the cosmetic mirror cover is closed and the cosmetic mirror is shielded and protected. At the same time, the lock core 133 moves to the second locking position along the guide slide 210 and is locked.

[0032] When the user needs to open the cosmetic mirror cover, the first time the operation part is pressed, the operation force drives the floating drive assembly to move downward against the elastic support force, in the process, the transmission part moves synchronously, converting the vertical downward movement into the power to drive the cosmetic mirror cover to open, so that the cosmetic mirror cover is gradually rolled up; at the same time, the lock core 133 on the locking part moves along the closed path of the guide slide 210, and finally reaches the first locking position and completes the locking, at this time the user releases the operation part, and the cosmetic mirror cover remains in the fully open state (i.e. the rolled-up state), and will not be closed automatically due to vehicle vibration.

[0033] When the user needs to close the mirror cover after use, the operation part is pressed again, and the floating drive assembly moves downward again under the pressure, and exits the first locking position, at this time the user releases the operation part, and the floating drive assembly starts to elastically reset upward under the resetting action of the elastic support structure itself, the lock core 133 continues to move along the closed path of the guide slide 210, reaches the second locking position and completes the locking. In the process of upward resetting of the floating drive assembly, the transmission part moves reversely, driving the cosmetic mirror cover to gradually close (i.e. the unfolded state), until the floating drive assembly is fully reset, and the cosmetic mirror cover is stably closed.

[0034] The cosmetic mirror cover of the embodiment can realize opening and closing switching through simple pressing operation, the operation feels soft, and the harsh touch during use is effectively improved; the cosmetic mirror cover is in a rolled-up state after being opened, which does not occupy additional space and can completely separate from the user's line of sight, without any angle blocking to the cosmetic mirror, and the opening angle is not limited, so that the user has a wide visual range during use, and the problem of visual depression caused by the traditional structure is completely solved; at the same time, the structure does not need to configure a complex magnetic component, and on the basis of controlling the cost and weight of the product, the opening and closing states of the cosmetic mirror cover are stable and reliable, and will not be mistakenly opened due to vehicle vibration, which balances excellent use experience and use safety.

[0035] Embodiment two The embodiment specifically limits the closed movement path of the guide slide 210, and by defining the path nodes and the movement law of the lock core 133, the stability and accuracy of the opening and closing of the mirror cover are further improved, and the problem of easy jamming or inaccurate positioning of the mirror cover position switching in the existing structure is solved.

[0036] In the opening and closing structure of the sun visor mirror cover for vehicles, as shown in Figure 6 The closed movement path formed by the guide slide 210 includes first node 211, second node 212, third node 213 and fourth node 214 in sequence, and each node is smoothly transitioned. The four nodes divide the closed path into four continuous movement segments, and each node corresponds to a key position of the lock core 133, ensuring the controllability of the movement of the lock core 133.

[0037] In response to a first pressing operation on the operation part, the lock core 133 moves from the first node 211 to the second node 212 and is locked at the third node 213, corresponding to the opening and locking of the cosmetic mirror cover; in response to a second pressing operation on the operation part, the lock core 133 moves from the third node 213 to the fourth node 214 and returns to the first node 211 to be locked, corresponding to the closing and locking of the cosmetic mirror cover.

[0038] The relationship between each node and the corresponding movement of the lock core 133 and the state of the mirror cover is as follows: when the cosmetic mirror cover is in a completely closed state, the lock core 133 is stably parked at the first node 211 (i.e., the second locking position), at which time the floating drive assembly is in a naturally reset state. When the user performs a first pressing operation on the operation part, the floating drive assembly moves downward, driving the lock core 133 to move along the guide slide 210 from the first node 211, first passing through the second node 212, which is an intermediate point for the lock core 133 to transition from the closed position to the open position, ensuring the stability of the movement direction; then the lock core 133 continues to move to the third node 213, which is the first locking position, where the lock core 133 is stably locked, at which time the floating drive assembly stops moving downward and remains in a compressed state, and the corresponding cosmetic mirror cover is completely opened and locked, allowing the user to normally use the cosmetic mirror without being affected by vehicle shaking.

[0039] When the user has finished using it, a second pressing operation is performed on the operation part, the floating drive assembly moves downward again against the elastic force, driving the lock core 133 to move from the third node 213 to the fourth node 214, which is an intermediate point for the lock core 133 to transition from the open position to the closed position, at which time the operation part cannot continue to move downward, and the user releases the operation part. Under the action of the elastic support structure of the floating drive assembly, it begins to elastically reset upward, and under the action of the elastic reset force of the floating drive assembly, the lock core 133 moves along the guide slide 210 from the fourth node 214 to the first node 211, and when it reaches the first node 211, the lock core 133 is locked again, at which time the floating drive assembly is completely reset, and the cosmetic mirror cover is completely closed and locked.

[0040] Through the setting of the four nodes, the movement trajectory of the lock core 133 is accurately defined, and each position switching has a clear node as a positioning reference, avoiding the deviation or jamming of the lock core 133 in the slide, ensuring that the mirror cover can be stably locked in both open and closed states, and at the same time making the pressing operation stroke more reasonable and improving the consistency of the user's operation feel.

[0041] Embodiment Three On the basis of Embodiment Two, the guide slide 210 connecting the nodes is specifically designed, and by reasonably planning the inclination direction of the slide, the smoothness of the movement of the lock core 133 is ensured, and the operation resistance is reduced.

[0042] The guide slide 210 connecting the first node 211 and the second node 212 is inclined from the first node 211 to the lower left, which matches the movement direction of the lock core 133 when the floating driving assembly is first pressed down. When the user presses the operation part, the lock core 133 can naturally slide downward along the inclined slide, without the need to additionally overcome the transverse resistance, thereby reducing the pressing force required for operation.

[0043] The guide slide 210 connecting the second node 212 and the third node 213 is inclined from the second node 212 to the upper left, which realizes smooth transition of the movement direction of the lock core 133 from downward to upward, and cooperates with the upward reset elastic force of the floating driving assembly, so that the lock core 133 can smoothly reach the first locking position, avoiding accidental sliding of the lock core 133 from the third node 213 when the vehicle is jolted.

[0044] The guide slide 210 connecting the third node 213 and the fourth node 214 is inclined from the third node 213 to the lower left, which matches the movement direction of the lock core 133 when the user presses the operation part again, ensuring that the lock core 133 can quickly escape from the locking state of the third node 213 and smoothly move downward along the inclined slide, thereby providing stable power transmission for the closing action of the cosmetic mirror cover.

[0045] The guide slide 210 connecting the fourth node 214 and the first node 211 is inclined from the fourth node 214 to the upper left, which matches the elastic reset direction of the floating driving assembly. When the floating driving assembly is reset upward, the lock core 133 can naturally slide upward along the guide slide 210 until it returns to the first node 211 to complete locking. The inclined design to the upper left can guide the lock core 133 to accurately return to the initial position, and the reset force can enhance the locking effect, ensuring that the mirror cover is tightly closed after being closed, thereby avoiding gaps.

[0046] Preferably, the guide slide 210 connecting the first node 211 and the second node 212 and the guide slide 210 connecting the fourth node 214 and the first node 211 are approximately symmetrically arranged, with similar inclination angles and lengths, and the longer length ensures that the movement speed of the lock core 133 is moderate, thereby avoiding rapid opening of the cosmetic mirror cover due to excessive speed.

[0047] Embodiment Four This embodiment specifically refines the structure of the operation part, and ensures the convenience and stability of operation by reasonably arranging the constituent parts.

[0048] The support part comprises a fixed support plate 111 serving as a mounting base of the operation part, which is made of high-strength plastic or metal plate and has sufficient rigidity to provide stable support for the entire floating drive assembly and avoid deformation or shaking during pressing. The support plate 111 is also provided with corresponding mounting hole positions for assembling other components to ensure accurate positioning of each structure.

[0049] The operation part comprises a floating plate 112 and a pressing rod 113. The floating plate 112 is arranged parallel above the support plate 111 and is elastically connected between the floating plate 112 and the support plate 111. The pressing rod 113 is fixed vertically on the floating plate 112 and extends upward to form an operation end, which can be designed as an arc-shaped top plate structure to increase the contact area with the user's fingers, improve the pressing feel, and avoid user discomfort caused by excessive local pressure.

[0050] When the user presses the operation end of the pressing rod 113, the pressure is transmitted to the floating plate 112 through the pressing rod 113, and the floating plate 112 moves downward against the elastic force between the floating plate 112 and the support plate 111, driving the transmission part and the locking part to move synchronously. When the pressure is removed, the floating plate 112 drives the pressing rod 113 to reset upward to the preset position under the action of the elastic force. This structure design makes the force transmission direct and uniform, avoids force loss, reduces the required force for operation, and ensures the stability of movement through the parallel arrangement of the floating plate 112 and the support plate 111.

[0051] Example Five This embodiment specifically designs the elastic connection mode between the floating plate 112 and the support plate 111 and related structures to ensure the stability and reliability of elastic reset.

[0052] The floating plate 112 and the support plate 111 are elastically connected by a spiral spring 114 arranged above the support plate 111, and the axis of the spiral spring 114 is arranged vertically to the support plate 11. The two ends of the spiral spring 114 can be connected in a positioning manner: a circular positioning groove is pre-set on the lower surface of the floating plate 112 and the upper surface of the support plate 111, and the upper and lower ends of the spiral spring 114 are matched with the corresponding positioning grooves. The inner diameter of the positioning groove matches the outer diameter of the spiral spring 114 to prevent the ends of the spring from shifting horizontally during the movement of the floating plate 112, ensure that the spiral spring 114 is always in an axial vertical state, and avoid tilting or misalignment. The spiral spring 114 has the advantages of simple structure, stable elastic performance, and low cost, can provide continuous and uniform reset force for the floating plate 112, and avoid reset jamming or incomplete reset.

[0053] The two helical springs 114 in the embodiment are symmetrically arranged around the pressing rod 113, and the symmetric arrangement enables the two helical springs 114 to bear force uniformly when the floating plate 112 is pressed, avoids the inclination of the floating plate 112 caused by unilateral force, ensures the floating plate 112 to move up and down in a horizontal state, and enables the symmetrically arranged helical springs 114 to provide balanced reset force when reset, so that the floating plate 112 is reset stably and the consistency of the operation feeling is further improved.

[0054] The helical spring 114 is provided with a guide rod 115, which has sufficient rigidity and will not bend during the expansion and contraction of the spring. One end of the guide rod 115 is fixedly arranged, and the other end is movably penetrated through the corresponding floating plate 112 or support plate 111. Specifically, the guide rod 115 can be arranged in two ways: one end of the guide rod 115 is fixed on the support plate 111, and the other end is movably penetrated through the floating plate 112; the other end of the guide rod 115 is fixed on the floating plate 112, and the other end is movably penetrated through the support plate 111. Both of the two ways can make the guide rod 115 guide the movement of the floating plate 112, ensure the vertical movement of the floating plate 112 along the axis direction of the guide rod 115, and realize the precise guidance of the movement of the floating plate 112.

[0055] The arrangement of the guide rod 115 effectively avoids the lateral deviation or distortion of the helical spring 114 during the expansion and contraction, ensures the spring to always expand and contract along the axis direction, prolongs the service life of the spring, and makes the entire elastic connection structure more stable and reliable.

[0056] Embodiment six The embodiment specifically refines the structure of the transmission part, adopts a gear and rack transmission mechanism, and realizes efficient conversion of the movement form. The transmission part includes a rotating shaft 121, an elastic reset member, a gear 122, and a rack 123.

[0057] The rotating shaft 121 is a direct power component for driving the opening and closing of the cosmetic mirror cover. After assembly, both ends of the rotating shaft 121 are rotatably fixed on the sunshade body through bearings. The arrangement of the bearings can improve the smoothness of the rotation of the rotating shaft and reduce the rotation resistance. The rotating shaft is connected with one end of the soft cosmetic mirror cover, so that the connection strength is sufficient to drive the movement of the cosmetic mirror cover and has sufficient torque transmission capacity.

[0058] The stretching direction of the elastic reset member is perpendicular to the axis of the rotating shaft, and the direction is arranged to enable the elastic reset member to form a reasonable cooperation between the pulling direction of the cosmetic mirror cover and the rotating driving force direction of the rotating shaft, thereby ensuring the stability of the movement track of the cosmetic mirror cover. One end of the elastic reset member is connected to the other end of the cosmetic mirror cover, and the other end of the elastic reset member is fixedly arranged. After assembly, the fixed end of the elastic reset member is fixed on the sun visor body. After the cosmetic mirror cover is wound on the rotating shaft, the elastic reset member is in a stretched state, and at this time, the elastic reset member has elastic potential energy to return to the natural state.

[0059] Preferably, the elastic reset member includes two tension springs connected to the upper and lower corners of the same end of the cosmetic mirror cover, respectively. The distance between the two tension springs is greater than the width of the mirror surface of the cosmetic mirror, so that after the cosmetic mirror cover is wound, the elastic reset member is stretched and does not block the mirror surface of the cosmetic mirror.

[0060] The gear 122 is fixed on the rotating shaft 121, and the gear 122 and the rotating shaft 121 are connected in an interference fit or a key connection manner to ensure synchronous rotation of the two and avoid relative sliding. The rack 123 is fixed vertically on the floating plate 112 and is in meshing engagement with the gear 122. The rack 123 and the gear 122 always remain in meshing engagement and do not slip.

[0061] When the user presses the operation part to move the floating plate 112 downward, the rack 123 fixed on the floating plate 112 moves downward synchronously, drives the gear 122 to rotate through meshing engagement, and the gear 122 drives the rotating shaft 121 to rotate synchronously. In the rotating process of the rotating shaft 121, the cosmetic mirror cover is gradually opened and wound on the rotating shaft. In this process, the other end of the cosmetic mirror cover pulls the elastic reset member to gradually stretch and store elastic potential energy. When the user finishes using, the operation part is pressed again to move downward, and when the floating plate 112 is reset upward under the action of the elastic force, the rack 123 moves upward synchronously, drives the gear 122 to rotate reversely, and the gear 122 drives the rotating shaft 121 to rotate reversely. At the same time, the elastic reset member releases the elastic potential energy and pulls the cosmetic mirror cover to gradually unfold from the rotating shaft 121. Under the combined action of the reverse rotation of the rotating shaft 121 and the pulling force of the elastic reset member, the cosmetic mirror cover is stably unfolded to the closed position.

[0062] Through the transmission cooperation of the rack 123 and the gear 122, the vertical stroke of the floating plate 112 can be converted into the required rotation angle of the rotating shaft 121. This gear 122 and rack 123 transmission mode has the advantages of high transmission efficiency, accurate movement, and stable structure, can realize efficient conversion of the vertical movement of the floating plate 112 and the rotating movement of the rotating shaft 121, ensure the stable and smooth opening and closing action of the cosmetic mirror cover, and avoid the jamming and wear problems of the traditional transmission structure.

[0063] Example Seven The connecting structure of the rotating shaft 121 and the cosmetic mirror cover is specifically designed in this embodiment. The rotating shaft 121 is provided with buckles 124 connected with the cosmetic mirror cover at both ends.

[0064] Specifically, the rotating shaft 121 is provided with buckles 124 connected with the cosmetic mirror cover at both ends (the buckles 124 are located inside the bearing mounting positions at both ends of the rotating shaft 121), and the buckles 124 are made of elastic material, such as high-strength elastic plastic, which has a certain deformation capacity, facilitating installation and disassembly, and can also provide sufficient connection strength. The structure of the buckle 124 can be designed as L-shaped or hook-shaped, matched with the pre-set buckle groove on the hinged side of the cosmetic mirror cover. The size and shape of the buckle groove are accurately matched with the buckle 124 to ensure that there is no looseness after connection. During installation, only the buckles 124 at both ends of the rotating shaft 121 are aligned with the buckle grooves of the cosmetic mirror cover, and the buckle 124 can be fixed by pressing lightly, completing the connection of the rotating shaft 121 and the cosmetic mirror cover. When repairing or replacing parts, only a certain external force is applied to make the buckle 124 elastically deform, and the buckle 124 can be separated from the buckle groove, realizing the separation of the two.

[0065] The buckle 124 connection method has the following advantages: first, it is convenient to install without using additional fasteners such as screws, simplifying the assembly process and improving production efficiency; second, the connection is firm, and the close fit of the buckle 124 and the buckle groove can ensure that the rotating shaft 121 and the cosmetic mirror cover move synchronously without relative sliding, ensuring the reliability of power transmission; third, it is easy to maintain, and when the cosmetic mirror cover or the rotating shaft 121 is damaged, it can be quickly disassembled for repair or replacement, reducing maintenance costs; fourth, the structure is simple, the buckle 124 is directly integrated at both ends of the rotating shaft 121, without the need for additional connection components, reducing the number of parts and the overall cost. Through the buckle 124 connection, the practicability and reliability of the connection between the rotating shaft 121 and the cosmetic mirror cover are effectively improved, ensuring that the power of the transmission part can be stably transmitted to the mirror cover to achieve smooth opening and closing.

[0066] Embodiment Eight The locking portion includes a locking rod 131 which is fixed vertically on the floating plate 112, ensuring that the locking rod 131 moves synchronously with the floating plate 112 and does not displace relatively. The locking rod 131 passes through the support plate 111 downward, and a guide hole matched with the locking rod 131 is arranged on the support plate 111. The inner diameter of the guide hole matches the outer diameter of the locking rod 131, ensuring that the locking rod 131 does not deviate when moving up and down, and ensuring the linearity of movement. An end of the locking rod 131 passing through the support plate 111 is formed with a lock head 132 which is a cylindrical structure. The lock head 132 is movably inserted into the lock sleeve 200, and a lock core 133 protruding radially is arranged on the lock head 132. The lock head 132 can move freely up and down in the lock sleeve 200. In the process of moving up and down of the lock head 132, the lock sleeve 200 is driven to rotate by the cooperation of the lock core 133 and the guide slide 210.

[0067] The size of the lock core 133 matches the guide slide 210 on the lock sleeve 200, and the lock core 133 can be embedded in the guide slide 210 and slide along the slide. When the lock core 133 moves along the guide slide 210 to the locking position, the structure design of the guide slide 210 can limit the lock core 133 and prevent it from continuing to move without external force, thereby realizing the locking function. The locking portion has simple structure and high reliability. Through the synchronous movement of the locking rod 131 and the floating plate 112, the lock core 133 is precisely moved in the guide slide 210, ensuring that the cosmetic mirror cover can be stably locked in the open and closed states, and avoiding accidental movement.

[0068] As shown in Figure 1 The locking rod 131 can also have a guiding function, and it simultaneously serves as a guide rod 115 arranged in a spiral spring 114, that is, the guide rod 115 in the spiral spring 114 and the locking rod 131 are the same component, realizing integrated design of guiding and locking transmission.
