Description

Technical Field

[0001] The present invention belongs to the technical field of folding screens, and specifically relates to an automatic folding and extending device for a vehicle-mounted folding screen based on unidirectional linear motion, and also relates to an automatic folding and extending method for a vehicle-mounted folding screen based on unidirectional linear motion. Background Art

[0002] At present, foldable screens are not only used in electronic products in life such as mobile phones, pads, etc., but also in car screens. However, in car screens, they are basically a whole piece and cannot be folded. In order to further enhance the technological interior experience brought by car screens, many manufacturers plan to push foldable screens into cars, and use a button-activated method to retract and extend the foldable screen to attract consumers.

[0003] However, the interior space of the car is limited, and many folding screens have the following problems during loading and unfolding:

[0004] 1) The retraction and extension of the folding screen are controlled by a power system, and the relative expansion and folding of the folding screen are controlled by a system. The two systems are relatively independent and cannot form a synergy, resulting in a complex structure, high cost, and increased failure rate;

[0005] 2) Because the two actions are performed separately, that is to say, the folding and unfolding operations can only be performed after the folding screen-related components are fully unfolded. Not only is a large space required, but some parts are also unfolded at any time, which affects the aesthetics of the interior itself and causes a poor user experience. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new method for automatically folding and unfolding a folding screen based on unidirectional linear motion.

[0007] It also involves a vehicle-mounted folding screen automatic folding and unfolding device based on unidirectional linear motion.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A method for automatically unfolding a folding screen based on unidirectional linear motion includes an outward unfolding process and an inward folding process. In the outward unfolding process, the following steps are included:

[0010] M1, open a position

[0011] The door is opened from the hatch. At this time, the folding screen is in an upper and lower folding state. The upper follower mold base and the lower follower mold base installed on the upper screen body and the lower screen body are relatively separated and located at the upper and lower sides, and the upper follower mold base and the lower follower mold base both slide on the upper guide rail and the lower guide rail, wherein the upper guide rail and the lower guide rail both include a translation section and a flattening section;

[0012] M2, sports expansion and flattening

[0013] The folding screen is pushed outward in one direction along a straight line perpendicular to the hatch opening and gradually extends outward from the hatch opening, and the upper follower mold base and the lower follower mold base maintain their initial state and slide along the translation section until the upper follower mold base and the lower follower mold base enter the flattening section, and the upper follower mold base and the lower follower mold base are driven to relatively approach and flip and open the folding screen while maintaining the one-way push, and the upper follower mold base and the lower follower mold base fit and contact and clamp the top driving force joint connected to the folding screen to form a one-way self-locking, the folding screen is in a flattened state, and the upper follower mold base and the lower follower mold base and the top driving force joint connected to the back of the folding screen are all located on the inner side of the hatch opening, and the folding screen is close to the hatch opening for shielding;

[0014] The inward folding process includes the following steps:

[0015] S1, fold inward

[0016] The folding screen is pushed inwardly along a straight line perpendicular to the hatch, and the one-way self-locking is unlocked. The upper follower mold base and the lower follower mold base gradually separate along the flattening section to drive the folding screen to move up and down and fold, and continue to move inward along the one-way straight line. At this time, the upper follower mold base and the lower follower mold base slide along the translation section until the folding screen is completely retracted into the inner side of the hatch;

[0017] S2. Close the position

[0018] The hatch is closed by resetting the hatch door, hiding the entire folding screen.

[0019] Preferably, in the one-way self-locking of step M2, the flattening section forms a motion limiter for the upper follower mold base and the lower follower mold base. That is, the flattening section further assists the one-way self-locking to improve the stability of the unfolding; at the same time, it reduces the retraction caused by accidental touching of the folding screen.

[0020] According to a specific implementation and preferred aspect of the present invention, in step M2, the translation section extends along the direction perpendicular to the opening of the warehouse, and the flattening section arches forward from the end of the translation section in an arc shape, the vertical distance from the center of the arc to the center line of the translation section is equal to the radius of the arc, and the arc of the upper guide track extends forward and upward; the arc of the lower guide track extends forward and downward. Here, based on the one-way self-locking, the upper screen body and the lower screen body are prevented from flipping open in a transitional manner, and the stability of the flattened display screen is also improved; in addition, the one-way self-locking will not affect the retraction operation of the folding screen; at the same time, based on the vertical distance from the center of the arc to the center line of the translation section being equal to the radius of the arc, therefore, not only the moving path is determined, but also the distance that the folding screen extends out of the mounting seat is controlled. In other words, under this path, the distance that the folding screen extends out of the mounting seat is the shortest, and it can still maintain a coherent movement between flipping and translation under linear power.

[0021] Preferably, the arc-shaped ends of the upper guide rail and the lower guide rail extend inward, and when forming a one-way self-locking, the arc-shaped flattened section forms a motion restriction with the upper follower mold base and the lower follower mold base. That is, by forming a connection between the flattened section, the upper follower mold base and the lower follower mold base, the one-way self-locking is assisted, the stability of the unfolding is improved, and the retraction caused by accidentally touching the folding screen is reduced.

[0022] In some specific embodiments, at least two upper guide rails are used and are spaced side by side along the length of the hatch; the lower guide rails correspond to each other and are symmetrically arranged up and down. Based on the motion guide formed by multiple groups, the motion synchronization between the upper screen and the lower screen is optimized.

[0023] Preferably, there are two upper guide rails and two lower guide rails, and the upper follower mold seat is slidably installed between the two upper guide rails from the follower columns on both sides; the lower follower mold seat is slidably installed between the follower columns on both sides. The movement of the follower columns drives the synchronous flipping of the upper and lower follower mold seats.

[0024] According to another specific implementation and preferred aspect of the present invention, in step S1, the upper follower mold base and the lower follower mold base are synchronously flipped symmetrically about the folding center line, and move to the inner end of the translation section to form a resistance limit. Based on the end limit, the inward stroke is effectively controlled, and the stroke is more stably supported.

[0025] According to another specific implementation and preferred aspect of the present invention, in steps M1 and S2, the door is opened or closed by a shift mechanism, wherein the door moves in an up-down or left-right direction. Generally, when a single door is used, up-down movement is adopted, and when a double door is used, up-down movement or left-right movement can be adopted. However, in view of the space limitation, up-down movement is the most preferred.

[0026] Preferably, a slide rail extending up and down is provided inside the mounting seat, and the door slides on the slide rails from the slide seats on both sides respectively, and the shifting mechanism is a pulley assembly or sprocket assembly based on a conveyor belt or a conveyor chain. The conveyor belt or the conveyor chain pulls the slide seat relative to the slide rail to open or close the door.

[0027] In addition, the door and the hatch are both tilted upward, and the folding screen moves outward and inward in a direction perpendicular to the door, and when unfolded, the upper screen body and the lower screen body are flush and form a display surface parallel to the door, which meets the needs of the vehicle display angle.

[0028] Another technical solution of the present invention is: an automatic folding and unfolding device used in the automatic folding and unfolding method of a folding screen based on unidirectional linear motion as mentioned above, which includes a mounting seat, a folding screen assembly, and a power assembly, wherein a compartment opening and a compartment door are formed on the mounting seat, and the compartment door can move to open or close the compartment opening; the folding screen assembly includes a folding screen, an upper screen body and a lower screen body on which the folding screens are respectively mounted and rotated around a folding center line, and an upper follower mold base and a lower follower mold base are respectively fixed on the back sides of the upper screen body and the lower screen body; the power assembly includes a fixed seat with an avoidance groove extending along the direction of the compartment opening, a guide mold base located on the fixed seat and having a movable track, a top driving force joint connecting the rotating parts of the upper screen body and the lower screen body, and a power device that pushes the top driving force joint linearly along the direction of the compartment opening to move closer to or away from the inside, wherein the upper guide track and the lower guide track constitute a group of tracks, and multiple groups of tracks are formed on the guide mold base.

[0029] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0030] During the loading process of the existing folding screen, the inward and outward movement of the folding screen is controlled by a set of power systems, and the relative expansion and folding of the folding screen is controlled by a set of systems, and the two systems are independent and cannot form a coordinated structure, resulting in a complex structure, high cost, and an increased failure rate. In addition, because the two actions are performed separately, that is, the folding and extending operation can only be performed after the relevant parts of the folding screen are fully unfolded, not only is the space required large, but some parts are also extended at any time, which affects the aesthetics of the folding screen, thereby causing poor user experience and other deficiencies. The present application comprehensively designs a method for automatic folding and extending of a folding screen based on unidirectional linear motion, which cleverly solves the deficiencies and defects of the prior art and adopts the method based on unidirectional linear motion. After the folding screen is automatically retracted and extended, the door is opened from the compartment opening during the outward expansion process. At this time, the folding screen is in an upper and lower folded state, and the upper follower mold base and the lower follower mold base installed on the upper screen body and the lower screen body are relatively separated and located at the upper and lower sides, and the upper follower mold base and the lower follower mold base both slide on the upper guide rail and the lower guide rail, wherein the upper guide rail and the lower guide rail both include a translation section and a flattening section; then the folding screen is pushed outward in a unidirectional manner along a straight line direction perpendicular to the compartment opening to gradually extend outward from the compartment opening, and the upper follower mold base and the lower follower mold base maintain their initial state and slide along the translation section until the upper follower mold base and the lower follower mold base enter the flattening section, and the upper follower mold base and the lower follower mold base are driven to move in a unidirectional manner. The follower mold base is relatively close to flip and open the folding screen, and the upper follower mold base and the lower follower mold base are fitted, abutted and clamped to the top driving force joint of the folding screen to form a one-way self-locking. The folding screen is flattened, and the upper follower mold base and the lower follower mold base and the top driving force joint connected to the back of the folding screen are all located on the inner side of the warehouse opening, and the folding screen is close to the warehouse opening for shielding; during the inward folding process, the folding screen is first pushed inward in a one-way direction along a straight line perpendicular to the warehouse opening to fold inward, the one-way self-locking is unlocked, and the upper follower mold base and the lower follower mold base are gradually separated along the flattening section to drive the folding screen to move up and down and fold, and continue to retract inward along the one-way straight line motion. At this time, the upper follower mold base and the lower follower mold base slide along the translation section until the folding The screen is completely retracted into the inner side of the hatch; then the hatch is closed based on the resetting of the hatch door to hide the entire folding screen. Therefore, on the one hand, the present invention is based on the unidirectional movement along the straight line direction perpendicular to the hatch, and cooperates with the motion guide path formed by the translation section and the flattening section to form synchronization and continuity between retraction or extension and flipping, that is, the retraction and extension are completed in the cooperation of mutual movement, which not only optimizes the power structure, but also reduces the cost and failure rate; on the other hand, based on the cooperation between the two movements, the folding screen assembly does not need to be completely exposed, and the unfolded folding screen is in a unidirectional self-locking state and flattened close to the hatch, while effectively shortening the required stowage and expansion space, and can form effective shielding to improve the overall aesthetics.

[0055] like Figures 1 to 13 As shown, the present embodiment involves an automatic folding and unfolding method of a folding screen based on unidirectional linear motion, and the automatic folding and unfolding device adopted therein includes a mounting seat 1, a folding screen assembly 2, and a power assembly 3.

[0056] Specifically, the hatch 10 and the hatch door 11 are arranged to be tilted upward, the mounting base 1 is assembled with the vehicle-mounted frame through the periphery, and a hatch 10 extending left and right is formed on the mounting base 1, the hatch door 11 is slidably installed on the mounting base 1, and the hatch 10 of the mounting base 1 is opened or closed based on the sliding of the hatch door 11.

[0057] In some specific embodiments, slide rails 12 are provided on opposite sides of the mounting base 1, and the warehouse door 11 is docked by a slide seat 13 sliding on the slide rails 12. At the same time, a shifting mechanism 14 is provided at one end of the warehouse opening 10 to drive the slide seat 13 to move to open or close the warehouse opening. The shifting mechanism 14 is a pulley assembly or a sprocket assembly based on a conveyor belt or a conveyor chain. The conveyor belt or the conveyor chain pulls the slide seat to move relative to the slide rail to open or close the warehouse opening.

[0058] Specifically, the shift mechanism 14 includes three power wheels a distributed in a triangle, and an annular belt b wound around the three power wheels a, wherein the annular belt b is fixedly connected to the slide 13, and the movement of the annular belt b drives the slide 13 to move up and down along the slide rail 12. In short, one side of the annular belt b extends in the up-down direction, so that the lifting and lowering adjustment of the slide 13 is implemented based on the movement of the annular belt b extending up and down, and then the opening and closing of the warehouse door 11 is implemented.

[0059] The folding screen assembly 2 includes a folding screen 20, an upper screen body 21 and a lower screen body 22 on which the folding screen 20 is respectively mounted and rotated around a folding center line, that is, the upper screen body 21 and the lower screen body 22 are folded and turned upside down around a folding center line so that the folding screen 20 is folded and flattened. The upper follower mold base 4 and the lower follower mold base 5 are respectively fixed on the backs of the upper screen body 21 and the lower screen body 22.

[0060] The power assembly 3 includes a fixed seat 30 having an escape groove extending along the direction of the inlet and outlet port 10, a guide mold seat 31 located on the fixed seat 30 and having a moving track, a top driving force joint 32 connecting the rotating parts of the upper screen body 21 and the lower screen body 22, and a power device 33 for linearly pushing the top driving force joint 32 toward or away from the inlet and outlet port 10. The fixed seat 30 is a conventional base, and the fixed seat 30 includes a seat plate 300, a bottom plate 301 and an end plate 302 located on opposite sides and forming a U-shaped escape groove q, and the folded upper screen body 21 and the lower screen body 22 can move from the U-shaped escape groove q; the guide mold seat 31 includes an upper mold body 310 and a lower mold body 311, wherein an upper guide track g is formed on the upper mold body 310, and a lower guide track t is formed on the lower mold body 311, and the upper mold body 310 and the lower mold body 311 are symmetrically arranged, that is, the upper guide track g and the lower guide track t are symmetrically arranged. The power device 33 includes a jacking force joint 330 connected to the rotating connection part of the upper screen body 21 and the lower screen body 22, and a power member 331 that drives the jacking force joint 330 to move linearly along the length direction perpendicular to the warehouse door 11, wherein the upper follower mold base 4 and the lower follower mold base 5 are respectively formed with avoidance gaps k, and when the upper screen body 21 and the lower screen body 22 are in the unfolded state, the upper follower mold base 4, the lower follower mold base 5 and the jacking force joint 330 cooperate to flatten the upper screen body 21 and the lower screen body 22 in a clamping manner. The power component 331 includes a power screw rod d extending in a direction perpendicular to the length of the warehouse door 11, a sliding module e cooperating with the power screw rod d, and a power motor f driving the power screw rod d to rotate forward and reversely, wherein the sliding module e includes a sliding seat e1 parallel to the power screw rod d, and a sliding sleeve e2 sleeved on the sliding seat e1, the sliding sleeve e2 is fixed to the top driving force joint 330, and the power screw rod d and the sliding sleeve e2 constitute a screw nut structure.

[0061] In this example, the upper mold body 310 and the lower mold body 311 form a group, and the guide mold base 31 is formed into two groups. The upper guide rail g and the lower guide rail t both have a translation section h1 and a flattening section h2. Under the linear push of the power device 33, the upper follower mold base 4 and the lower follower mold base 5 synchronously and continuously retract and unfold the upper screen body 21 and the lower screen body 22 during the movement of the translation section h1 and the flattening section h2, and when the upper screen body 21 and the lower screen body 22 are in the expanded state, the upper follower mold base 4 and the lower follower mold base 5 are in relative contact and form a one-way lock based on the flattening section h2. At the same time, the upper follower mold base 4 and the lower follower mold base 5 are hidden on the inner side of the mounting base 1 and block the corresponding position of the warehouse opening 10. In some specific embodiments, the translation segment h1 extends along the direction of entering and exiting the warehouse door 11, and the flattening segment h2 is arranged to be forward and outwardly arched from the end of the translation segment close to the warehouse door 11, wherein the upper screen body 21 and the lower screen body 22 are synchronously driven to be relatively folded or unfolded based on the flattening segment h2 during the linear motion of the power device 33. That is, the entry and exit mounting seat 1 is formed based on the linear translation segment h1, and the upper screen body 21 and the lower screen body 22 are relatively folded or unfolded based on the flattening segment h2, and the movements of the two can be continuous, and all parts do not need to be fully extended from the mounting seat to flip, and the movement can only be continuous at a specific position to avoid the bay opening 10 of the mounting seat 1. In this example, the translation section h1 is perpendicular to the length direction of the warehouse door 11, and the flattened section h2 is an arc with a smooth transition. The flattened section h2 arches forward from the end of the translation section h1 in an arc shape, and the vertical distance from the center of the arc to the center line of the translation section h1 is equal to the radius of the arc. The flattened section h2 of the upper guide rail g is tilted upward and forward, and the flattened section h2 of the lower guide rail t is tilted downward and forward. At the same time, the end of the tilted arc extends inward, and based on the interference of the inner extension end and the interference of the upper and lower follower seats 33, a one-way self-locking is formed. Here, one-way self-locking is used to prevent the upper screen body and the lower screen body from flipping open in a transitional manner, and at the same time, the stability of the flattened display screen is improved; in addition, the one-way self-locking will not affect the retraction operation of the folding screen; at the same time, the vertical distance from the center of the arc to the center line of the translation segment is equal to the radius of the arc, therefore, not only the moving path is determined, but also the distance that the folding screen extends out of the mounting seat is controlled. In other words, under this path, the distance that the folding screen extends out of the mounting seat is the shortest, and it can still maintain continuous motion between flipping and translation under linear power.

[0062] In addition, the upper follower mold base 4 slides on the two upper guide rails g from the two follower pins respectively; the lower follower mold base 5 slides on the two lower guide rails t from the two follower pins respectively. Based on the synchronous displacement of the follower pins, the synchronous coordination of the contraction and expansion is improved, and the limit self-locking is formed in the buckling and pressing resistance formed by the follower pins, which further improves the stability of the flattening.

[0063] In summary, the method for automatically unfolding and retracting a folding screen based on unidirectional linear motion in this embodiment includes an outward unfolding process and an inward folding process. In the outward unfolding process, the following steps are included:

[0064] M1, open a position

[0065] The door is opened from the hatch. At this time, the folding screen is in an upper and lower folding state. The upper follower mold base and the lower follower mold base installed on the upper screen body and the lower screen body are relatively separated and located at the upper and lower sides, and the upper follower mold base and the lower follower mold base both slide on the upper guide rail and the lower guide rail, wherein the upper guide rail and the lower guide rail both include a translation section and a flattening section;

[0066] M2, sports expansion and flattening

[0067] The folding screen is pushed outward in one direction along a straight line perpendicular to the hatch opening and gradually extends outward from the hatch opening, and the upper follower mold base and the lower follower mold base maintain their initial state and slide along the translation section until the upper follower mold base and the lower follower mold base enter the flattening section, and the upper follower mold base and the lower follower mold base are driven to relatively approach and flip and open the folding screen while maintaining the one-way push, and the upper follower mold base and the lower follower mold base fit and contact and clamp the top driving force joint connected to the folding screen to form a one-way self-locking, the folding screen is in a flattened state, and the upper follower mold base and the lower follower mold base and the top driving force joint connected to the back of the folding screen are all located on the inner side of the hatch opening, and the folding screen is close to the hatch opening for shielding;

[0068] The inward folding process includes the following steps:

[0069] S1, fold inward

[0070] The folding screen is pushed inwardly along a straight line perpendicular to the hatch, and the one-way self-locking is unlocked. The upper follower mold base and the lower follower mold base gradually separate along the flattening section to drive the folding screen to move up and down and fold, and continue to move inward along the one-way straight line. At this time, the upper follower mold base and the lower follower mold base slide along the translation section until the folding screen is completely retracted into the inner side of the hatch;

[0071] S2. Close the position

[0072] The hatch is closed by resetting the hatch door, hiding the entire folding screen.

[0073] In some specific embodiments, in the one-way self-locking of step M2, the flattening section forms a motion limit for the upper follower mold base and the lower follower mold base. That is, the one-way self-locking is further assisted by the flattening section to improve the stability of the unfolding; at the same time, the retraction caused by accidentally touching the folding screen is reduced. In step M2, the translation section extends in a direction perpendicular to the opening of the warehouse, and the flattening section arches forward from the end of the translation section to form an arc, the vertical distance from the center of the arc to the center line of the translation section is equal to the radius of the arc, and the arc of the upper guide track extends forward and upward; the arc of the lower guide track extends forward and downward. Here, based on the one-way self-locking, the upper screen body and the lower screen body are prevented from being flipped open in transition, and the stability of the flattened display screen is also improved; in addition, the one-way self-locking will not affect the retraction operation of the folding screen; at the same time, based on the vertical distance from the center of the arc to the center line of the translation section is equal to the radius of the arc, therefore, not only the moving path is determined, but also the distance of the folding screen extending out of the mounting seat is controlled. In other words, under this path, the distance of the folding screen extending out of the mounting seat is the shortest, and it can still maintain a coherent movement between flipping and translation under linear power. The arc ends of the upper guide rail and the lower guide rail both extend inward, and when the one-way self-locking is formed, the flattening section of the arc forms a motion restriction with the upper follower mold base and the lower follower mold base. That is, by forming an association between the flattening section, the upper follower mold base and the lower follower mold base, the one-way self-locking is assisted to improve the stability of the unfolding; at the same time, the retraction caused by accidentally touching the folding screen is reduced. In step S1, the upper follower mold base and the lower follower mold base maintain synchronous flipping symmetrically about the folding center line, and move to the inner end of the translation section to form a resistance limit. Based on the end limit, the inward stroke is effectively controlled, and the stroke is more stably supported. In steps M1 and S2, the warehouse door is opened or closed by a shifting mechanism, and the movement direction of the warehouse door is up and down or left and right. In general, when a single door is used, up and down movement is adopted, and when a double door is used, it can be up and down movement or left and right movement, but combined with the use of space limitations, up and down movement is the most preferred.

[0074] In addition, the door 11 and the hatch 10 are both tilted upward, and the folding screen extends and retracts in a direction perpendicular to the door 11, and when unfolded, the upper screen body 21 and the lower screen body 22 are flush and form a display surface parallel to the door 11. This meets the requirements of the vehicle display angle.

[0075] In summary, after adopting the automatic folding and unfolding method of the folding screen based on unidirectional linear motion, the compartment door is opened from the compartment opening during the outward unfolding process, at this time, the folding screen is in an upper and lower folded state, the upper follower mold base and the lower follower mold base installed on the upper screen body and the lower screen body are relatively separated and located at the upper and lower sides, and the upper follower mold base and the lower follower mold base both slide on the upper guide rail and the lower guide rail, wherein the upper guide rail and the lower guide rail both include a translation section and a flattening section; then the folding screen is pushed outward in a unidirectional manner along a straight line direction perpendicular to the compartment opening to gradually extend outward from the compartment opening, the upper follower mold base and the lower follower mold base maintain their initial state and slide along the translation section until the upper follower mold base and the lower follower mold base enter the flattening section, and the upper follower mold base and the lower follower mold base are driven relative to each other while maintaining the unidirectional push. The folding screen is nearly flipped and opened, and the upper follower mold base and the lower follower mold base are fitted, abutted and clamped to the top driving force joint of the folding screen to form a one-way self-locking. The folding screen is flattened, and the upper follower mold base and the lower follower mold base and the top driving force joint connected to the back of the folding screen are all located on the inner side of the hatch, and the folding screen is close to the hatch for shielding; during the inward folding process, the folding screen is first pushed inward in a one-way direction along a straight line perpendicular to the hatch to fold inward, the one-way self-locking is unlocked, and the upper follower mold base and the lower follower mold base are gradually separated along the flattening section to drive the folding screen to fold up and down, and continue to retract inward along the one-way straight line. At this time, the upper follower mold base and the lower follower mold base slide along the translation section until the folding screen is completely retracted into the inner side of the hatch; then based on the reset of the hatch door, the hatch is opened. The folding screen is closed and the entire folding screen is concealed. Therefore, on the one hand, the present invention is based on the motion guiding path formed by the translation section and the flattening section in the unidirectional motion along the straight line perpendicular to the hatch, so that the retraction or extension and the flipping are synchronized and connected, that is, the retraction and extension are completed in the mutual motion cooperation, which not only optimizes the power structure but also reduces the cost and failure rate; on the other hand, it is based on the cooperation between the two motions, so that the folding screen assembly does not need to be completely exposed, and the unfolded folding screen is in a unidirectional self-locking state and flattened close to the hatch, which effectively shortens the required stowage and unfolding space and can form an effective shielding to improve the overall aesthetics; on the third aspect, an entry and exit mounting seat is formed based on the straight line translation section, and the upper screen body and the lower screen body are relatively folded or unfolded based on the flattening section, and The movements of the two can be continuous, and all parts do not need to be extended out of the mounting seat to flip. At the same time, the movement can only be continuous at a specific position to avoid the opening of the mounting seat; the fourth aspect is based on the one-way self-locking to prevent the upper and lower screen bodies from flipping open in a transitional manner, and at the same time, the stability of the flattened display screen is improved; in addition, the one-way self-locking will not affect the retraction operation of the folding screen; the fifth aspect is based on the high degree of movement synchronization formed by the symmetrical track, and at the same time, the upper follower mold base and the lower follower mold base are symmetrically implemented to improve the synchronization and stability of the folding and unfolding of the folding screen; the sixth aspect is to distribute the power generated by flipping and folding on the folding center line through multiple groups of alignment, so that the driving force for the expansion or folding of the upper and lower screen bodies is relatively uniform, thereby improving the service life of the folding screen assembly;At the same time, the synchronous displacement of the follower pin improves the synchronous coordination of the retraction and expansion, and the limit self-locking is formed in the buckling and pressing resistance formed by the follower pin, further improving the stability of the flattening; the seventh aspect is based on the setting of the avoidance gap, when the upper and lower screen bodies are in the unfolded state, the upper and lower follower seats and the top driving force joint cooperate to flatten the upper and lower screen bodies in a clamping manner; the eighth aspect is based on the screw nut structure to implement stable pushing, and at the same time, based on the movement of the annular belt, the slide seat is driven to move up and down along the slide rail to realize the opening or closing of the warehouse door. ;
