Description
Technical Field
[0001] The utility model relates to the technical field of automotive sunroofs, in particular to a sliding limit structure, a sliding lifting assembly and a sliding sunroof. Background Art
[0002] As an important innovation in modern automotive design, the development background of automotive sliding sunroofs is closely linked to technological progress. Since the rise of the automotive industry in the early 20th century, people's demands for vehicle comfort and functionality have been continuously increasing. In order to meet consumers' pursuit of a wider field of vision, better ventilation effects and a more comfortable driving experience, automotive manufacturers have started to explore the application of sunroof technology.
[0003] Initially, sunroof designs were relatively simple, mostly fixed or manually operable. However, with the development of materials science, mechanical engineering and electronic control technology, sunroofs have gradually evolved into more complex and user-friendly systems. The emergence of sliding sunroofs marks an important milestone in automotive sunroof technology; sliding sunroofs allow users to adjust the opening and closing degree of the sunroof according to their needs, providing greater flexibility.
[0004] However, there are some deficiencies in the operation of existing sliding sunroofs, such as unstable sliding and inaccurate positioning. In particular, due to the relatively large self-weight of the sunroof, when retracting the sunroof, during the stage of the sunroof falling and closing, under the influence of gravity, the sunroof will accelerate its fall and vibrate or even produce abnormal noises, which all affect the user experience and the service life of the sunroof. Summary of the Utility Model
[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a sliding limit structure, a sliding lifting assembly and a sliding sunroof, so as to solve the problems of rapid falling, vibration and abnormal noises caused by the self-weight of the sliding sunroof during the process of falling and closing in the prior art.
[0006] To solve the above technical problem, the utility model provides a sliding limit structure, comprising:
[0007] A limiter, in which a limit chute is arranged. The limit chute includes a horizontal section and a descending section connected to the horizontal section. The descending section extends downward of the horizontal section, and an elastic member is arranged at the bottom of the descending section;
[0008] A sliding foot, which is slidably arranged in the limit chute. When the sliding foot slides from the horizontal section to the descending section along the limit chute, the sliding foot abuts against the elastic member, and during the process of sliding downward along the descending section, as the elastic member is gradually compressed, a gradually increasing elastic force is applied to the sliding foot to assist the sliding foot to fall smoothly.
[0009] As a more preferred embodiment, the descending section of the limit chute has an inclination. When the sliding foot slides downward along the descending section, a part of the gravity of the sliding foot is applied to the side wall of the limit chute, further ensuring the smoothness of the sliding foot when sliding along the descending section.
[0010] As a more preferred embodiment, the elastic member is a torsion spring.
[0011] As a more preferred embodiment, a fixing rod is provided at the bottom of the descending section of the limit chute. The torsion spring is sleeved on the fixing rod, with one end fixed and the other end movably arranged upward. When the sliding foot slides from the horizontal section to the descending section along the limit chute, the other end of the torsion spring abuts against the bottom of the sliding foot.
[0012] To solve the above problems, the present utility model further provides a sliding lifting assembly, including:
[0013] A slide rail and a slider. The slide rail includes a sliding foot chute and a positioning chute provided below the sliding foot chute. The slider is slidably arranged in the positioning chute;
[0014] For the above-mentioned sliding limit structure, the limiter is fixed on the slide rail, and the horizontal section of the limit chute is aligned with the sliding foot chute;
[0015] A lifting arm. The lifting end of the lifting arm is connected to the sliding foot, and the other end is hinged to the slider. When the sliding foot is at the bottom of the descending section, driving the lifting arm to move along the slide rail, the sliding foot slides from the descending section towards the horizontal section and continuously rises until it slides into the sliding foot chute. At the same time, the slider slides along the positioning chute. Since the sliding foot chute is located above the positioning chute and the horizontal section is aligned with the sliding foot chute, when the sliding foot slides to the horizontal section, the lifting end of the lifting arm connected to the sliding foot tilts up; driving the lifting arm in the reverse direction, the sliding foot slides into the horizontal section along the sliding foot chute and continues to slide downward smoothly along the descending section, and during the descending process, the lifting end retracts.
[0016] As a more preferred embodiment, the bottom of the descending section of the limit chute is lower than the positioning chute.
[0017] As a more preferred embodiment, the descending section of the limit chute enables the sliding foot to rotate a certain angle while sliding along the descending section to adapt to the angle change during the tilting and retracting processes of the lifting arm.
[0018] To solve the above problems, the present utility model further provides a sliding sunroof, including:
[0019] Two sets of the above-mentioned sliding lifting assemblies, and the two slide rails are symmetrically arranged;
[0020] A skylight assembly includes a skylight glass and two support rods, wherein the two support rods are provided at two ends of opposite sides of the skylight glass to provide support for the skylight glass, and the support rods are connected to the lifting ends of the corresponding lifting arms;
[0021] When the lifting arm slides along the slide rail, the sunroof assembly is first driven to rise by the lifting end, and then slides along the slide rail, so that the sunroof assembly is opened; when the lifting arm slides in the opposite direction along the slide rail, the sunroof assembly is first driven to slide to the closed position, and then the sunroof assembly is driven to descend by the retraction of the lifting end, so that the sunroof assembly is closed.
[0022] As a more preferred embodiment, the sliding sunroof also includes two front tilting structures respectively arranged on the two sliding rails, the rear end of the support rod is hinged to the lifting end, and the front end is hinged to the front tilting structure. When the sunroof assembly is opened, the lifting end and the front tilting structure first simultaneously drive the sunroof assembly to rise, and then drive the sunroof assembly to slide forward along the sliding rails; when the sunroof assembly is closed, the lifting end and the front tilting structure first simultaneously drive the sunroof assembly to slide backward along the sliding rails, and when moving to the closed position, drive the sunroof assembly to descend.
[0023] As a more preferred embodiment, the sunroof assembly further includes a front crossbeam and a rear crossbeam, and the front crossbeam and the rear crossbeam are arranged below the two ends of the other opposite side of the sunroof glass to support the sunroof glass.
[0024] As described above, the sliding limiting structure, sliding lifting assembly and sliding sunroof of the present invention have the following beneficial effects: when the sliding limiting structure of the present invention is in use, the sliding foot slides in the limiting sliding groove, and when the sliding foot slides from the horizontal section to the descending section along the limiting sliding groove, the sliding foot abuts against the elastic member, and in the process of sliding downward along the descending section, as the elastic member is gradually squeezed, a gradually increasing elastic force is applied to the sliding foot, assisting the sliding foot to fall smoothly; similarly, when the sliding foot slides from the descending section to the horizontal section along the limiting sliding groove, the elastic member also applies a gradually decreasing elastic force to the sliding foot, assisting the sliding foot to rise smoothly;
[0025] For the sliding and lifting assembly of the present utility model, when the sliding foot is located at the bottom of the descending section, it drives the lifting arm to move along the slide rail. The sliding foot slides along the descending section towards the horizontal section and continuously rises until it slides into the sliding foot chute. At the same time, the slider slides along the positioning chute. Since the sliding foot chute is located above the positioning chute and the horizontal section is aligned with the sliding foot chute, when the sliding foot slides to the horizontal section, the lifting end of the lifting arm connected to the sliding foot tilts upwards; when the lifting arm is driven in the reverse direction, the sliding foot slides into the horizontal section along the sliding foot chute and continues to slide smoothly downwards along the descending section. During the descending process, the lifting end retracts; due to the adoption of the above-mentioned sliding limit structure, the tilting and retraction of the lifting end of the lifting arm are smoother;
[0026] For the sliding skylight of the present utility model, which adopts the above-mentioned sliding and lifting assembly, when the sliding skylight is closed, the sliding foot slides downwards along the descending section of the limit chute, driving the retraction of the lifting end of the lifting arm, causing the skylight assembly to descend. During this closing process, the sliding foot abuts against the elastic member. As the elastic member is gradually compressed, an increasingly large elastic force is exerted on the sliding foot, assisting the sliding foot to fall smoothly, and thus enabling the smooth closing of the skylight assembly; similarly, the above-mentioned elastic member also assists in the smooth opening of the skylight assembly;
[0027] For the sliding limit structure, the sliding and lifting assembly, and the sliding skylight of the present utility model, by providing an elastic member at the bottom of the limit chute, as the skylight assembly opens and closes, an elastic force for supporting is assisted to be exerted on the skylight assembly, achieving the smooth opening and closing of the skylight assembly, and solving the problems of rapid falling, jitter, and abnormal noise caused by its own weight during the falling and closing process of the sliding skylight in the prior art.

[0055] As Figures 1 to 4 shown, the present utility model provides a sliding limit structure 1, comprising:
[0056] A stopper 11, within which a limit chute 111 is provided. The limit chute 111 includes a horizontal section 111a and a descending section 111b connected to the horizontal section 111a. The descending section 111b extends downward of the horizontal section 111a, and an elastic member 13 is provided at the bottom of the descending section 111b;
[0057] A sliding foot 12, which is slidably disposed within the limit chute 111. When the sliding foot 12 slides from the horizontal section 111a to the descending section 111b along the limit chute 111, the sliding foot 12 abuts against the elastic member 13, and during the downward sliding along the descending section 111b, as the elastic member 13 is gradually compressed, an increasingly large elastic force is applied to the sliding foot 12 to assist the sliding foot 12 to fall smoothly.
[0058] To better introduce the sliding limit structure 1 of the present utility model, the following specific embodiments are now combined for illustration: When the sliding limit structure 1 of the present utility model is in use, the sliding foot 12 slides in the limit sliding groove 111, and when the sliding foot 12 slides from the horizontal section 111a to the descending section 111b along the limit sliding groove 111, the sliding foot 12 abuts against the elastic member 13, and during the downward sliding along the descending section 111b, as the elastic member 13 is gradually compressed, an increasingly large elastic force is exerted on the sliding foot 12 to assist the sliding foot 12 to fall smoothly; similarly, when the sliding foot 12 slides from the descending section 111b to the horizontal section 111a along the limit sliding groove 111, the elastic member 13 also exerts a gradually decreasing elastic force on the sliding foot 12 to assist the sliding foot 12 to rise smoothly.
[0059] In this embodiment, the descending section 111b of the limit sliding groove 111 has an inclination. When the sliding foot 12 slides downward along the descending section 111b, a part of the gravity of the sliding foot 12 is exerted on the side wall of the limit sliding groove 111, further ensuring the smoothness of the sliding foot 12 during the sliding in the descending section 111b; furthermore, in this embodiment, the descending section 111b of the limit sliding groove 111 can be V-shaped, that is, it includes two downhill slopes connected end to end, further controlling the sliding track 2 of the sliding foot 12 and further ensuring that a part of the gravity of the sliding foot 12 is exerted on the side wall of the limit sliding groove 111.
[0060] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, the elastic member 13 is a torsion spring.
[0061] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, a fixed rod is provided at the bottom of the descending section 111b of the limit sliding groove 111. The torsion spring is sleeved on the fixed rod, fixed at one end and movably arranged upward at the other end. When the sliding foot 12 slides from the horizontal section 111a to the descending section 111b along the limit sliding groove 111, the other end of the torsion spring abuts against the bottom of the sliding foot 12.
[0062] To solve the above problems, as Figure 1 、 Figure 2 and Figure 3 shown, the present utility model also provides a sliding lifting assembly, including:
[0063] A slide rail 2 and a slider 3. The slide rail 2 includes a sliding foot slide groove 21 and a positioning slide groove 22 provided below the sliding foot slide groove 21. The slider 3 is slidably arranged in the positioning slide groove 22;
[0064] The above-mentioned sliding limit structure 1, the stopper 11 is fixed on the slide rail 2, and the horizontal section 111a of the limit chute 111 is aligned with the slide foot chute 21;
[0065] The lifting arm 4, the lifting end 41 of the lifting arm 4 is connected to the slide foot 12, and the other end is hinged to the slider 3. When the slide foot 12 is at the bottom of the descending section 111b, the lifting arm 4 is driven to move along the slide rail 2, and the slide foot 12 slides along the descending section 111b towards the horizontal section 111a and continuously rises until it slides into the slide foot chute 21. At the same time, the slider 3 slides along the positioning chute 22. Since the slide foot chute 21 is above the positioning chute 22 and the horizontal section 111a is aligned with the slide foot chute 21, when the slide foot 12 slides to the horizontal section 111a, the lifting end 41 of the lifting arm 4 connected to the slide foot 12 tilts up; when the lifting arm 4 is driven in the reverse direction, the slide foot 12 slides into the horizontal section 111a along the slide foot chute 21 and continues to slide smoothly downward along the descending section 111b, and during the descending process, the lifting end 41 retracts.
[0066] In order to better introduce the sliding and lifting assembly of the present invention, the following specific embodiments are now combined for description: For the sliding and lifting assembly of the present invention, when the slide foot 12 is at the bottom of the descending section 111b, the lifting arm 4 is driven to move along the slide rail 2, and the slide foot 12 slides along the descending section 111b towards the horizontal section 111a and continuously rises until it slides into the slide foot chute 21. At the same time, the slider 3 slides along the positioning chute 22. Since the slide foot chute 21 is above the positioning chute 22 and the horizontal section 111a is aligned with the slide foot chute 21, when the slide foot 12 slides to the horizontal section 111a, the lifting end 41 of the lifting arm 4 connected to the slide foot 12 tilts up; when the lifting arm 4 is driven in the reverse direction, the slide foot 12 slides into the horizontal section 111a along the slide foot chute 21 and continues to slide smoothly downward along the descending section 111b, and during the descending process, the lifting end 41 retracts; due to the adoption of the above-mentioned sliding limit structure 1, the tilting up and retraction of the lifting end 41 of the lifting arm 4 are smoother.
[0067] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, the bottom of the descending section 111b of the limit chute 111 is lower than the positioning chute 22.
[0068] In this embodiment, as Figure 1 、 Figure 2 and Figure 3As shown, the descending section 111b of the limit sliding groove 111 satisfies that the sliding foot 12 rotates by a certain angle while sliding along the descending section 111b to adapt to the angle change of the lifting arm 4 during the tilting and retracting processes.
[0069] To solve the above problems, as Figure 4 shown, the present utility model further provides a sliding sunroof, comprising:
[0070] Two sets of the above-mentioned sliding lifting assemblies, and two of the slide rails 2 are symmetrically arranged;
[0071] A sunroof assembly 5, comprising a sunroof glass and two support rods 51. The two support rods 51 are arranged at both ends of a relative side of the sunroof glass to provide support for the sunroof glass, and the support rods 51 are connected to the lifting ends 41 of the corresponding lifting arms 4;
[0072] When the lifting arm 4 slides along the slide rail 2, first, the tilting of the lifting end 41 drives the sunroof assembly 5 to rise, and then it slides along the slide rail 2, so that the sunroof assembly 5 is opened; when the lifting arm 4 slides reversely along the slide rail 2, first, it drives the sunroof assembly 5 to slide to the closed position, and then the retraction of the lifting end 41 drives the sunroof assembly 5 to descend, so that the sunroof assembly 5 is closed.
[0073] To better introduce the sliding sunroof of the present utility model, the following specific embodiments are now combined for illustration: For the sliding sunroof of the present utility model, the above-mentioned sliding lifting assembly is adopted. When the sliding sunroof is closed, the sliding foot 12 slides downward along the descending section 111b of the limit sliding groove 111, driving the retraction of the lifting end 41 of the lifting arm 4 to make the sunroof assembly 5 descend. During this closing process, the sliding foot 12 abuts against the elastic member 13. As the elastic member 13 is gradually compressed, an increasingly large elastic force is applied to the sliding foot 12 to assist the sliding foot 12 to fall smoothly, thereby enabling the smooth closing of the sunroof assembly 5; similarly, the above-mentioned elastic member 13 also assists the smooth opening of the sunroof assembly 5; it can be seen that by arranging the elastic member 13 at the bottom of the limit sliding groove 111, as the sunroof assembly 5 is opened and closed, an elastic force for supporting is assisted to be applied to the sunroof assembly 5, realizing the smooth opening and closing of the sunroof assembly 5, and solving the problems of rapid falling, jitter, and abnormal noise caused by its own weight during the falling and closing process of the sliding sunroof in the prior art.
[0074] In this embodiment, as Figure 4As shown, the sliding sunroof further includes two front tilting structures 6 respectively disposed on the two slide rails 2. The rear end of the support rod 51 is hinged to the lifting end 41, and the front end is hinged to the front tilting structure 6. When the sunroof assembly 5 is opened, the lifting end 41 and the front tilting structure 6 first drive the sunroof assembly 5 to rise simultaneously, and then drive the sunroof assembly 5 to slide forward along the slide rail 2. When the sunroof assembly 5 is closed, the lifting end 41 and the front tilting structure 6 first drive the sunroof assembly 5 to slide backward along the slide rail 2, and when moving to the closed position, drive the sunroof assembly 5 to descend.
[0075] In this embodiment, as Figure 4 shown, the sunroof assembly 5 further includes a front cross beam 52 and a rear cross beam 53. The front cross beam 52 and the rear cross beam 53 are disposed below the two opposite ends of the other side of the sunroof glass to support the sunroof glass.
[0076] In summary, the sliding limit structure, the sliding lifting assembly and the sliding sunroof of the present utility model have the following advantages:
[0077] 1. Smooth sliding: Through the elastic member 13 disposed in the limit chute 111, the sliding foot 12 obtains a gradually changing elastic force during the sliding process, ensuring smooth falling and rising.
[0078] 2. Compact structure: The horizontal section 111a of the limit chute 111 is connected to the descending section 111b to form a compact limit structure, which is convenient for integration and installation.
[0079] 3. Inclination design: The inclination design of the descending section 111b causes part of the gravity of the sliding foot 12 to be applied to the side wall during the descending process, increasing the sliding stability.
[0080] 4. V-shaped descending section 111b: The V-shaped design further controls the descending track 2 of the sliding foot 12, ensuring the smoothness and accuracy of the sliding process.
[0081] 5. Torsion spring elastic member 13: A torsion spring is used as the elastic member 13 to provide a stable and reliable elastic force to assist the smooth sliding of the sliding foot 12.
[0082] 6. Fixed rod design: The torsion spring is sleeved on the fixed rod, with one end fixed and the other end movable, ensuring the stable transmission of the elastic force.
[0083] 7. Sliding lifting assembly: Combining the slide rail 2 and the slider 3 to form a sliding lifting assembly to realize the lifting control of the sliding foot 12.
[0084] 8. Lifting arm 4 drive: The drive of the lifting arm 4 realizes the rising and falling of the sliding foot 12, driving the slider 3 to slide along the positioning chute 22 to realize complex movements.
[0085] 9. Integration of the sunroof assembly 5: Applying the sliding and lifting assembly to the sunroof assembly 5 to achieve smooth opening and closing of the sunroof.
[0086] 10. Front tilting structure 6: The design of the front tilting structure 6 enables the sunroof assembly 5 to rise first and then slide forward along the slide rail 2 when opening, and vice versa when closing.
[0087] 11. Design of the support rod 51: The support rod 51 connects the lifting arm 4 and the sunroof assembly 5 to provide stable support and transmit motion.
[0088] 12. Elastic force assistance: The elastic member 13 provides an auxiliary force during the opening and closing processes of the sunroof assembly 5 to ensure smooth opening and closing, reduce jitter and abnormal noises.
[0089] Through its innovative design, the sliding limit structure 1 of this patent achieves smooth sliding of the sliding foot 12 within the limit sliding groove 111. The arrangement of the elastic member 13 enables the sliding foot 12 to obtain a gradually changing elastic force during the sliding process, ensuring the smoothness and accuracy of the sliding. The slope design and the V-shaped descending section 111b further control the sliding trajectory of the sliding foot 12, increasing stability. The torsion spring, as the elastic member 13, provides a stable and reliable auxiliary force. The design of the sliding and lifting assembly and the lifting arm 4 achieves precise control of the sliding foot 12, and the integration of the sunroof assembly 5 applies this technology to the actual product to achieve smooth opening and closing of the sunroof. The design of the front tilting structure 6 and the support rod 51 provides additional stability and motion control, enabling the sunroof assembly 5 to perform complex motions smoothly. Overall, the sliding limit structure 1 of this patent and its application solve the problems of rapid falling, jitter, and abnormal noises of the sliding sunroof in the prior art, providing a smooth and reliable sliding control solution.
