Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile sunroof, especially to a front and rear track sliding locking structure and soft top sunroof. BACKGROUND

[0002] In the equipment that needs to realize the sliding of components through the track (such as automobile sunroof, building sliding window), the connection and locking of the track are the key link. The early track structure is mostly integral type, although it does not need to be connected, but it has the problems of large space occupation and low installation flexibility - for example, if the large sunroof adopts the integral track, the track is easy to deform due to collision in the transportation and installation process, affecting the smooth running of the sliding component. With the development of equipment towards modularity and light weight, segmented track gradually becomes the mainstream, that is, through the butt joint of the front track and the rear track, the function of "expanding and shrinking according to needs" is realized, which is widely used in retractable sunroof, soft top sunroof, folding door and other equipment.

[0003] However, the existing front and rear track sliding locking structure has many defects in actual application, and it is difficult to meet the use requirements of high precision and high reliability:

[0004] Firstly, the linkage of locking and unlocking is poor, and the operation is complicated. The existing structure mostly adopts independent locking mechanism (such as manual bolt, buckle), and the track needs to be additionally manually operated (such as screwing the bolt, pressing the buckle) after butt joint to realize fixation, and the unlocking also needs to be separately operated, which cannot be synchronized with the movement of the sliding component. For example, in the soft top sunroof, after the sliding cover plate drives the slide foot to move along the track to the butt joint position, the user needs to pause the sliding action and manually trigger the locking mechanism, which not only affects the smoothness of operation, but also may cause the track to separate due to forgetting to lock, causing safety hazards.

[0005] Secondly, the locking reliability is insufficient and is easy to fail due to vibration or external force. The existing locking structure mostly adopts single contact point or relies on the simple elastic force of the elastic element to realize clamping. When the equipment is subjected to vibration (such as bumping during driving) or external force impact, the single contact point is easy to loosen, and the elastic force of the elastic element may also weaken due to fatigue, causing the locking mechanism to be accidentally unlocked, causing the relative sliding of the track, affecting the normal operation of the equipment - for example, the accidental unlocking of the sunroof track may cause the sliding cover plate to deviate, causing problems such as rain leakage and air leakage.

[0006] Thirdly, the locking precision is low, and the butt joint deviation is large. The existing structure lacks precise guiding and positioning design of the butt joint position of the track, and the front track and the rear track are easy to deviate horizontally or vertically when butt joint. For example, the coaxiality of the positioning hole and the locking pin is difficult to guarantee, causing the locking pin to jam when inserted, or even unable to be completely inserted, which not only aggravates the wear of the components, but also cannot form effective locking, further affecting the movement precision of the sliding component (such as the sunroof cover plate), causing problems such as sliding jamming and abnormal noise.

[0007] In view of the above problems, there is an urgent need for a front and rear track sliding locking structure that can be synchronized with the movement of the sliding part to achieve locking and unlocking, has reliable locking, high precision, and strong adaptability, so as to improve the operation stability and operation convenience of the segmented track equipment. Content of the utility model

[0008] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a front and rear track sliding locking structure and a soft-top sunroof, so as to solve the poor linkage between the segmented track locking and the sliding foot movement in the prior art.

[0009] In order to solve the above technical problems, the utility model provides a front and rear track sliding locking structure, comprising:

[0010] A front track is provided with a front module guide block, and the front module guide block is provided with a positioning hole in the rear direction along the extension direction of the front track;

[0011] A rear track is arranged on the rear side of the front track, and the extension direction of the rear track is consistent with that of the front track, and the rear track is provided with a rear locking module, the rear locking module comprises a mounting seat, a connecting rod assembly and a trigger shaft, wherein the mounting seat is provided with an expansion slot, the connecting rod assembly is arranged in the expansion slot, one end of the trigger shaft is connected with the connecting rod assembly, and the other end of the trigger shaft is provided with a rotating knob located on the path of the front track and the rear track;

[0012] A sliding foot slides along the front track and the rear track, the sliding foot moves along the front track and the rear track and pushes the rotating knob, thereby driving the trigger shaft to rotate, and simultaneously driving the connecting rod assembly to move along the expansion slot, so that the end of the connecting rod assembly is engaged with or separated from the positioning hole.

[0013] As a more preferred mode, the rotating knob comprises a first contact surface and a second contact surface perpendicular to each other, when the slide foot moves from the rear rail to the front rail, it passes through the trigger shaft and contacts the first contact surface, pushing the trigger shaft to rotate, driving the end of the linkage assembly to be clamped into the positioning hole, and the front rail is locked with the rear rail; when the slide foot moves from the front rail to the rear rail, it passes through the trigger shaft and contacts the second contact surface, pushing the trigger shaft to rotate, driving the end of the linkage assembly to be separated from the positioning hole, and the front rail is unlocked with the rear rail; the beneficial effect is that the first contact surface and the second contact surface of the rotating knob are perpendicular to each other, corresponding to the forward and backward movement directions of the slide foot respectively, so that the slide foot can be accurately triggered to lock when moving forward and accurately triggered to unlock when moving backward, and the action logic is clear and unambiguous. This directional triggering design avoids locking failure or unlocking jam caused by misoperation, ensures the accuracy of rail locking and unlocking, simplifies the cooperation relationship between the slide foot and the knob, and reduces the structural machining precision requirement.

[0014] As a more preferred mode, the linkage assembly comprises a telescopic rod, a swing rod and a transmission rod; the mounting seat is provided with a telescopic groove consistent with the extension direction of the rear rail, the telescopic rod is arranged in the telescopic groove, the telescopic rod comprises a connecting end and a positioning end matched with the positioning hole, the connecting end is provided with a swing groove, the bottom of the telescopic groove is provided with a first arc-shaped groove and a second arc-shaped groove, one end of the swing rod is provided with a first positioning pin, the positioning pin passes through the telescopic groove and is arranged in the first arc-shaped groove, the other end of the swing rod is provided with a second positioning pin, the second positioning pin passes through one end of the transmission rod and is arranged in the second arc-shaped groove, the other end of the transmission rod is sleeved with the trigger shaft, the trigger shaft drives the transmission rod to rotate around the shaft center, and in turn drives the other end of the swing rod to swing along the second arc-shaped groove, and at the same time drives one end of the swing rod to swing along the first arc-shaped groove, and in the swinging process, the telescopic rod is driven to reciprocate along the telescopic groove; the beneficial effect is that the linkage assembly converts the rotation of the trigger shaft into the linear reciprocating motion of the telescopic rod through the multi-stage linkage of the telescopic rod, the swing rod and the transmission rod, the transmission path is stable and the force transmission efficiency is high. The design of the arc-shaped groove provides accurate guidance for the movement of the swing rod, ensures that the telescopic rod can be smoothly inserted or separated from the positioning hole, and avoids jamming. This multi-component cooperative transmission structure not only ensures the accuracy of the locking action, but also enhances the impact resistance of the structure and prolongs the service life.

[0015] As a more preferred embodiment, the front and rear track sliding locking structure further includes a fixed locking pin and a locking hook adapted to the fixed shaft pin. The locking hook includes a rotating end, a claw end, and a connecting portion disposed between the rotating end and the claw end. The rotating end of the locking hook is rotatably mounted on the mounting base. The connecting portion of the locking hook is hinged to the first positioning pin. The first positioning pin moves forward along the first arc-shaped groove, driving the telescopic rod to insert into the positioning hole, and simultaneously driving the claw end of the locking hook to engage with the fixed locking pin. The first positioning pin moves backward along the first arc-shaped groove, driving the telescopic rod to disengage from the positioning hole, and simultaneously separating the claw end from the fixed locking pin. Its advantage lies in the "double locking" mechanism formed by the cooperation of the fixed locking pin and the locking hook: the telescopic rod inserting into the positioning hole achieves primary locking, and the claw end of the locking hook engaging with the fixed locking pin achieves secondary locking, significantly improving the reliability of track locking. Even if the telescopic rod develops gaps due to wear, the locking hook can still ensure that the track does not separate. Furthermore, the locking hook and the first positioning pin are linked, allowing for simultaneous completion of double locking without additional operation, simplifying the operation process.

[0016] To solve the above problems, this utility model also provides a soft-top skylight, including: a skylight and the aforementioned front and rear track sliding locking structure.

[0017] As a preferred embodiment, the flexible skylight includes two sets of front and rear track sliding locking structures and a sliding cover plate. The two sets of front and rear track sliding locking structures are symmetrically arranged on both sides of the skylight, and the sliding cover plate is connected to the sliding feet on both sides. The advantage is that the two symmetrical locking structures, respectively located on both sides of the skylight, ensure balanced force on both sides of the sliding cover plate, preventing tilting of the cover plate or deformation of the track caused by locking on one side. Simultaneous locking and unlocking on both sides ensures smooth overall movement of the skylight, improving the structural stability and service life of the flexible skylight. The symmetrical design also facilitates installation and maintenance.

[0018] As a preferred embodiment, the flexible sunroof also includes a cable structure, which is slidably mounted on the front and rear tracks. The flexible sunroof uses this cable structure to drive the sliding cover plate to slide along the front and rear tracks. The advantages are that, compared to traditional push-rod drives, the cable transmission is more flexible, adaptable to the complex spatial layout of flexible sunroofs, and produces less noise and wear. The cable, in conjunction with the track sliding locking structure, enables synchronized sliding of the cover plate and locking of the tracks, improving the smoothness of sunroof operation.

[0019] As a more preferred approach, the soft-top skylight also includes a cable drive unit connected to the cable structure. The advantage of this is that the cable drive unit provides power to the cable structure, enabling automated movement of the sliding cover without manual pushing or pulling, thus improving the convenience and intelligence of the soft-top skylight. The drive unit can precisely control the cable tension and movement speed, ensuring smooth sliding of the cover and avoiding jamming or impact caused by uneven manual operation.

[0020] As a more preferred approach, the flexible skylight also includes a track drive unit, which drives the rear track to engage or disengage from the front track. The advantage of this is that the track drive unit allows the flexible skylight to adjust its track configuration as needed, such as unfolding for use or retracting for storage, thus enhancing the system's flexibility. The automated control of the drive unit reduces manual intervention, lowers the risk of track alignment deviations, and ensures the accuracy of track alignment.

[0021] As a more preferred embodiment, the soft-top skylight also includes a control unit electrically connected to the cable drive unit and the track drive unit. The control unit synchronously controls the cable drive unit and the track drive unit to move the rear track and sliding cover forward. When the rear track abuts against the front track, the cable drive unit drives the sliding foot to insert the telescopic rod into the positioning hole, locking the front and rear guide rails. The control unit also synchronously controls the cable drive unit and the track drive unit to move the rear track and sliding cover backward. After the cable drive unit drives the sliding foot to disengage the telescopic rod from the positioning hole, the track drive unit then separates the rear track from the front track, ensuring coordinated movement of the track and cable. The advantage is that the control unit synchronously coordinates the cable drive unit and the track drive unit, ensuring that the tracks lock first when engaging and unlock first when disengaging, preventing the tracks from being subjected to force in an unlocked state or forcibly separated in an unlocked state, thus preventing structural damage. This collaborative control logic makes the operation process of the soft roof sunroof more standardized, improves the safety and reliability of the system, and at the same time, the automated control reduces human error and further optimizes the user experience.

[0022] As described above, the front and rear track sliding locking structure and soft-top skylight of this utility model have the following beneficial effects:

[0023] This utility model's front and rear track sliding locking structure uses the positioning hole of the front track to cooperate with the rear locking module of the rear track. By using the sliding foot to push the rotating lever, the linkage assembly can be engaged or disengaged from the positioning hole, thus locking and unlocking the track. The entire structure requires no complicated manual operation; the locking and unlocking actions are triggered by simply sliding the sliding foot. It is convenient to operate and responds quickly, effectively ensuring the stability of the front and rear tracks in the docked state, avoiding equipment failure caused by relative track displacement, and improving the reliability of the track structure.

[0024] This invention applies a front and rear track sliding locking structure to a soft-top skylight, enabling a stable lock after the skylight tracks are connected. This prevents the skylight from jamming or shifting due to track loosening during sliding, ensuring smooth opening and closing of the skylight. Simultaneously, the convenient triggering feature of the locking structure adapts to the automated operation requirements of the skylight, providing a crucial guarantee for the stable operation of the soft-top skylight.

[0025] In summary, the front and rear track sliding locking structure and soft roof skylight of this utility model achieve locking and unlocking between the front and rear tracks by sliding the foot on the front and rear tracks simultaneously, thus solving the problem of poor linkage between segmented track locking and foot movement in the prior art.

[0070] like Figures 1 to 5 As shown, this utility model provides a front and rear track sliding locking structure, including:

[0071] A front track 1, on which a front module guide block 2 is provided, and a positioning hole 21 is provided in the front module guide block 2 extending rearward along the extension direction of the front track 1;

[0072] The rear track 3 is located behind the front track 1 and extends in the same direction as the front track 1. A rear locking module 4 is provided on the rear track 3. The rear locking module 4 includes a mounting base 41, a connecting rod assembly 42, and a trigger shaft 43. The mounting base 41 is provided with a telescopic groove 411. The connecting rod assembly 42 is located in the telescopic groove 411. One end of the trigger shaft 43 is connected to the connecting rod assembly 42. The other end of the trigger shaft 43 is provided with a rotating paddle 431 located on the path between the front track 1 and the rear track 3.

[0073] The sliding foot 51 slides along the front rail 1 and the rear rail 3. The sliding foot 51 moves along the front rail 1 and the rear rail 3 and pushes the rotating paddle 431, thereby driving the trigger shaft 43 to rotate. At the same time, it drives the connecting rod assembly 42 to move along the telescopic groove 411, so that the end of the connecting rod assembly 42 engages or disengages from the positioning hole 21.

[0074] To better illustrate the front and rear track sliding locking structure of this utility model, the following specific application will be used as an example: The front and rear track sliding locking structure of this utility model uses the positioning hole 21 of the front track 1 to cooperate with the rear locking module 4 of the rear track 3. By using the sliding foot 51 to push the rotating lever 431, the connecting rod assembly 42 can be engaged or disengaged from the positioning hole 21, thus locking and unlocking the track. The entire structure requires no complex manual operation; the locking and unlocking actions are triggered simply by sliding the sliding foot 51. The operation is convenient and the response is rapid, effectively ensuring the stability of the front and rear tracks 3 in the docked state, avoiding equipment failure caused by relative track displacement, and improving the reliability of the track structure.

[0075] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the rotating paddle 431 includes a first contact surface 431a and a second contact surface 431b that are perpendicular to each other. When the sliding foot 51 moves forward from the rear rail 3, it passes through the trigger shaft 43 and contacts the first contact surface 431a, pushing the trigger shaft 43 to rotate, causing the end of the connecting rod assembly 42 to be engaged in the positioning hole 21, locking the front rail 1 and the rear rail 3. When the sliding foot 51 moves backward from the front rail 1, it passes through the trigger shaft 43 and contacts the second contact surface 431b, pushing the trigger shaft 43 to rotate, causing the end of the connecting rod assembly 42 to separate from the positioning hole 21, unlocking the front rail 1 and the rear rail 3. Its beneficial effect is that the first contact surface 431a and the second contact surface 431b of the rotating paddle 431 are perpendicular to each other, respectively corresponding to the forward and backward movement directions of the sliding foot 51, so that the sliding foot 51 can accurately trigger the locking when moving forward and accurately trigger the unlocking when moving backward, with clear and unambiguous action logic. This directional trigger design avoids locking failure or unlocking jamming caused by misoperation, ensuring the accuracy of track locking and unlocking, while simplifying the cooperation between the slide foot 51 and the lever, and reducing the requirements for structural machining precision.

[0076] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2As shown, the linkage assembly 42 includes a telescopic rod 421, a swing rod 422, and a transmission rod 423; the mounting base 41 is provided with a telescopic groove 411 that extends in the same direction as the rear track 3, the telescopic rod 421 is disposed in the telescopic groove 411, the telescopic rod 421 includes a connecting end 421b and a positioning end 421a that matches the positioning hole 21, the connecting end 421b is provided with a swing groove 421c, the bottom of the telescopic groove 411 is provided with a first arc-shaped groove 411a and a second arc-shaped groove 411b, one end of the swing rod 422 is provided with a first positioning pin 422a, the positioning pin passes through the telescopic groove 411 and is disposed in the first arc-shaped groove 411a, the other end of the swing rod 422 is provided with a second positioning pin 422b, the... The second positioning pin 422b passes through one end of the transmission rod 423 and is located in the second arc-shaped groove 411b. The other end of the transmission rod 423 is sleeved with the trigger shaft 43. The trigger shaft 43 drives the transmission rod 423 to rotate around its axis, thereby causing the other end of the swing rod 422 to swing along the second arc-shaped groove 411b. Simultaneously, it causes one end of the swing rod 422 to swing along the first arc-shaped groove 411a. During the swinging process, it causes the telescopic rod 421 to reciprocate along the telescopic groove 411. The beneficial effect is that the linkage assembly 42, through the multi-stage linkage of the telescopic rod 421, the swing rod 422, and the transmission rod 423, converts the rotation of the trigger shaft 43 into the linear reciprocating motion of the telescopic rod 421. The transmission path is stable and the force transmission efficiency is high. The arc-shaped groove design provides precise guidance for the movement of the swing rod 422, ensuring that the telescopic rod 421 can smoothly insert into or disengage from the positioning hole 21, avoiding jamming. This multi-component collaborative transmission structure not only ensures the accuracy of the locking action but also enhances the structure's impact resistance and extends its service life.

[0077] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the rear locking module 4 also includes an elastic element 44. One end of the elastic element 44 is fixed to the mounting base 41, and the other end is fixed to the other end of the swing rod 422. The elastic element 44 applies a spring force to the swing rod 422 to move forward. When the sliding foot 51 moves to the front rail 1, the spring force keeps the front rail 1 locked to the rear rail 3. Its beneficial effect is that the elastic element 44 provides a continuous forward spring force to the swing rod 422. After the sliding foot 51 moves to the front rail 1, the spring force can maintain the engagement state between the telescopic rod 421 and the positioning hole 21, preventing the lock from loosening due to vibration or external impact.

[0078] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2As shown, the front and rear track sliding locking structure also includes a fixed locking pin 6 and a locking hook 45 adapted to the fixed shaft pin. The locking hook 45 includes a rotating end 451, a claw end 453, and a connecting part 452 disposed between the rotating end 451 and the claw end 453. The rotating end 451 of the locking hook 45 is rotatably disposed on the mounting base 41. The connecting part 452 of the locking hook 45 is hinged to the first positioning pin 422a. The first positioning pin 422a moves forward along the first arc-shaped groove 411a, driving the telescopic rod 421 to insert into the positioning hole 21, and simultaneously driving the locking hook 45. The claw end 453 engages with the fixed locking pin 6, and the first positioning pin 422a moves rearward along the first arc-shaped groove 411a, causing the telescopic rod 421 to disengage from the positioning hole 21. Simultaneously, the claw end 453 separates from the fixed locking pin 6. The beneficial effect is that the cooperation between the fixed locking pin 6 and the locking hook 45 forms a "double locking" mechanism: the telescopic rod 421 inserts into the positioning hole 21 to achieve primary locking, and the claw end 453 of the locking hook 45 engages with the fixed locking pin 6 to achieve secondary locking, significantly improving the reliability of track locking. Even if the telescopic rod 421 develops gaps due to wear, the locking hook 45 can still ensure that the track does not separate. Furthermore, the locking hook 45 is linked with the first positioning pin 422a, allowing for simultaneous completion of double locking without additional operation, simplifying the operation process.

[0079] In some possible embodiments of this utility model, such as Figure 6 As shown, a track limiting block 31 is also provided on the rear track 3. The track limiting block 31 is located on the rear side of the sliding foot 51 to limit the displacement of the rear side of the sliding foot 51 and prevent the sliding foot 51 from disengaging from the rotating paddle 431.

[0080] To address the aforementioned problems, this utility model also provides a soft-top skylight, such as... Figure 7 as well as Figure 8 The diagram shown illustrates the opening and closing of the soft-top skylight, which includes the skylight and the aforementioned front and rear track sliding locking structure.

[0081] To better illustrate the flexible skylight of this invention, the following specific application will be used as an example: This invention applies a front and rear track sliding locking structure to a flexible skylight, achieving a stable lock after the skylight tracks are connected. This prevents the skylight from jamming or shifting due to track loosening during sliding, ensuring smooth opening and closing of the skylight. Simultaneously, the convenient triggering characteristic of the locking structure adapts to the automated operation requirements of the skylight, providing a crucial guarantee for the stable operation of the flexible skylight. It can be seen that the front and rear track sliding locking structure and the flexible skylight of this invention, through the sliding foot 51 sliding on the front track 1 and the rear track 3, achieve locking and unlocking between the front track 1 and the rear track 3, solving the problem of poor linkage between segmented track locking and the movement of the sliding foot 51 in the prior art.

[0082] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the soft-top skylight includes two sets of front and rear track sliding locking structures and a sliding cover plate 5. The two sets of front and rear track sliding locking structures are symmetrically arranged on both sides of the skylight, and the two sides of the sliding cover plate 5 are connected to the sliding feet 51. The advantage is that the two sets of symmetrical locking structures are respectively arranged on both sides of the skylight, so that the sliding cover plate 5 is subjected to balanced force on both sides, avoiding the tilting of the cover plate or deformation of the track caused by locking on one side. The synchronous locking and unlocking on both sides can ensure the smooth movement of the skylight as a whole, improve the structural stability and service life of the soft-top skylight, and the symmetrical design facilitates installation and maintenance.

[0083] In some possible embodiments of this utility model, the flexible skylight further includes a cable structure, which is slidably mounted on the front track 1 and the rear track 3. The flexible skylight drives the sliding cover 5 to slide along the front track 1 and the rear track 3 via the cable structure. The advantages are that, compared to traditional push-rod drives, the cable transmission is more flexible, adaptable to the complex spatial layout of the flexible skylight, and has low transmission noise and low wear. The cable, in conjunction with the track sliding locking structure, enables the linkage between the cover sliding and the track locking, improving the smoothness of skylight operation.

[0084] In some possible embodiments of this utility model, the soft-top skylight further includes a cable drive unit connected to the cable structure; its advantage lies in that the cable drive unit provides power to the cable structure, realizing the automated movement of the sliding cover 5 without manual pushing or pulling, thus improving the convenience and intelligence level of the soft-top skylight. The drive unit can precisely control the cable tension and movement speed, ensuring smooth sliding of the cover and avoiding jamming or impact caused by uneven manual operation.

[0085] In some possible embodiments of this utility model, the flexible skylight further includes a track drive unit, which drives the rear track 3 to engage or disengage from the front track 1. The advantage of this is that the track drive unit can engage or disengage the rear track 3 from the front track 1, allowing the flexible skylight to adjust its track status as needed, such as unfolding for use or retracting for storage, thus enhancing the system's flexibility. The automated control of the drive unit reduces manual intervention, lowers the risk of track engagement deviation, and ensures the accuracy of track engagement.

[0086] As a more preferred embodiment, the soft-top skylight also includes a control unit. The control unit is electrically connected to the cable drive unit and the track drive unit. The control unit synchronously controls the cable drive unit and the track drive unit to move the rear track 3 and the sliding cover 5 forward. When the rear track 3 abuts against the front track 1, the cable drive unit drives the sliding foot 51 to insert the telescopic rod 421 into the positioning hole 21, thereby locking the front guide rail and the rear guide rail. The control unit synchronously controls the cable drive unit and the track drive unit to move the rear track 3 and the sliding cover 5 backward. After the cable drive unit drives the sliding foot 51 to disengage the telescopic rod 421 from the positioning hole 21, the track drive unit then drives the rear track 3 to separate from the front track 1, ensuring the coordination of track movement and cable movement. The beneficial effect is that the control unit synchronously coordinates the cable drive unit and the track drive unit to ensure that the track is locked first when docking and unlocked first when separating, avoiding the track being subjected to force in an unlocked state or being forcibly separated in an unlocked state, thus preventing structural damage. This collaborative control logic makes the operation process of the soft roof sunroof more standardized, improves the safety and reliability of the system, and at the same time, the automated control reduces human error and further optimizes the user experience.

[0087] As described above, the front and rear track sliding locking structure and soft-top skylight of this utility model have the following beneficial effects:

[0088] 1. Easy to operate and quick to respond, ensuring stable track docking.

[0089] The entire structure requires no complicated manual operation. The sliding foot 51 can trigger the rear locking module 4 to lock and unlock the track simply by sliding on the front and rear tracks 3. The response is rapid. At the same time, it can effectively avoid equipment failure caused by relative displacement of the track, improve the reliability of the track structure, and when applied to soft roof skylights, it can adapt to the needs of automated skylight operation and ensure smooth opening and closing of the skylight.

[0090] 2. The 431 directional trigger design of the rotating lever ensures accurate track locking and unlocking.

[0091] The first contact surface 431a and the second contact surface 431b of the rotating lever 431 are perpendicular to each other and correspond to the forward and backward movement directions of the sliding foot 51, respectively. This allows the sliding foot 51 to accurately trigger locking when moving forward and accurately trigger unlocking when moving backward, with a clear action logic. This design avoids locking failure or unlocking jamming caused by misoperation, while simplifying the cooperation between the sliding foot 51 and the lever and reducing the requirements for structural machining precision.

[0092] 3. The linkage assembly features 42 stages of multi-stage linkage transmission, ensuring stable transmission and precise locking.

[0093] The linkage assembly 42, through multi-stage linkage of the telescopic rod 421, the swing rod 422, and the transmission rod 423, converts the rotation of the trigger shaft 43 into the linear reciprocating motion of the telescopic rod 421. The transmission path is stable and the force transmission efficiency is high. The arc groove provides precise guidance for the movement of the swing rod 422, ensuring that the telescopic rod 421 smoothly inserts into or disengages from the positioning hole 21 and avoids jamming. The multi-component collaborative transmission structure not only ensures the accuracy of the locking action but also enhances the structure's impact resistance and extends its service life.

[0094] 4. The elastic element 44 provides continuous elasticity to prevent the lock from loosening.

[0095] One end of the elastic element 44 is fixed to the mounting base 41 and the other end is fixed to the other end of the swing arm 422. It can apply a spring force to the swing arm 422 to move forward. When the sliding foot 51 moves to the front rail 1, the spring force can be used to keep the front rail 1 and the rear rail 3 locked, effectively preventing the lock from loosening due to vibration or external impact.

[0096] 5. The fixed locking pin 6 and the locking hook 45 cooperate to achieve double locking and improve reliability.

[0097] The cooperation between the fixed locking pin 6 and the locking hook 45 forms a "double locking" mechanism: the telescopic rod 421 is inserted into the positioning hole 21 to achieve the first-level locking, and the hook end 453 of the locking hook 45 engages with the fixed locking pin 6 to achieve the second-level locking, which greatly improves the reliability of track locking. Even if the telescopic rod 421 has gaps due to wear, the locking hook 45 can still ensure that the track does not separate; and the locking hook 45 is linked with the first positioning pin 422a, so that the double locking can be completed synchronously without additional operation, simplifying the operation process.

[0098] 6. The soft-top skylight features a symmetrical locking structure, enhancing structural stability and extending its service life.

[0099] The two sets of front and rear track sliding locking structures of the soft roof skylight are symmetrically arranged on both sides of the skylight, so that the force on both sides of the sliding cover 5 is balanced, avoiding the tilting of the cover or deformation of the track caused by locking on one side; the synchronous locking and unlocking on both sides can ensure the smooth movement of the skylight as a whole, and the symmetrical design facilitates installation and maintenance.

[0100] 7. The cable-stayed structure provides flexible transmission and improves the smoothness of sunroof operation.

[0101] The cable structure is slidably mounted on the front track 1 and the rear track 3, driving the sliding cover 5 to slide along the track. Compared with the traditional push rod drive, it is more flexible, can adapt to the complex spatial layout of soft roof sunroofs, and has low transmission noise and low wear. The cable and the track sliding locking structure work together to realize the linkage between the sliding of the cover and the locking of the track, improving the smoothness of sunroof operation.

[0102] 8. The drive unit enables automated movement, enhancing the convenience and intelligence of the soft-top sunroof.

[0103] The cable drive unit provides power to the cable structure, enabling the sliding cover 5 to move automatically without manual pushing or pulling; the track drive unit can drive the rear track 3 to connect or disconnect with the front track 1, allowing the soft roof skylight to adjust the track status as needed, enhancing flexibility; and the automated control of the two types of drive units reduces manual intervention, lowers the risk of track connection deviation, and ensures connection accuracy. The cable drive unit can also precisely control the cable tension and movement speed, avoiding jamming or impact caused by uneven manual operation.

[0104] 9. Coordinated control with the control unit enhances the safety and reliability of the soft-top sunroof.

[0105] The control unit is electrically connected to the cable drive unit and the track drive unit, and can control their actions synchronously: the track is locked first when docking and unlocked first when separating, to avoid the track being subjected to force in an unlocked state or being forcibly separated in an unlocked state, thus preventing structural damage; this collaborative control logic makes the operation process of the soft roof sunroof more standardized, while the automated control reduces human operation errors and optimizes the user experience.

[0106] The front and rear track sliding locking structure and soft roof sunroof of this patent have significantly improved in terms of ease of operation, accuracy of action, reliability of locking, and stability of transmission through multi-structure collaborative design. It can not only solve the problem of poor linkage between the existing segmented track locking and the sliding foot 51, but also provide stable, efficient and intelligent operation guarantee for the soft roof sunroof, and comprehensively optimize the track locking and sunroof user experience.

[0107] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0108] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
