Description

Technical Field

[0001] This utility model relates to the field of automotive equipment technology, and in particular to a stable and anti-collapse sunshade curtain. Background Technology

[0002] As an important feature for enhancing driving and riding comfort, the performance of the accompanying sunshade directly affects the user experience. Currently, sunshade products on the market generally suffer from three major problems: First, insufficient stability. During vehicle operation, road bumps, rapid acceleration, or sudden deceleration can cause the sunshade to sway, shift, or even get stuck in the guide rails. Especially at high speeds, the noise generated by this swaying can disrupt the quietness of the cabin. Second, inadequate anti-collapse performance. Most sunshades, lacking support, are prone to drooping under gravity after unfolding. When rolling up, the irregular shape of the drooping fabric can cause wrinkles and stacking, leading to jamming on the roller or guide rails, resulting in poor rolling or even damage. Third, poor positioning accuracy. Traditional sunshade braking structures often rely on simple friction pads, which are prone to wear after frequent use, making it impossible to precisely stop at any position, requiring repeated adjustments to achieve the ideal sunshade angle. Utility Model Content

[0003] The purpose of this invention is to propose a stable and anti-collapse sunshade curtain to solve the technical problems of insufficient stability, poor anti-collapse performance, and poor positioning progress that are common in existing car sunroof sunshades in the background art.

[0031] Preferably, a handle is provided at the center of the outer end of the movable rod.

[0032] One of the above technical solutions has the following beneficial effects:

[0033] 1. Precise and stable stopping: The elastic friction structure of the guide rail spring solves the positioning failure problem after the wear of traditional brake pads, and can stay stably at any position within the unfolding range, adapting to the sunshade needs of different sunlight angles;

[0034] 2. Anti-collapse and durable: The rigid support of the fabric support rod, combined with the high-strength curtain fabric, improves the flatness after unfolding, reduces the accident rate of unsmooth rewinding or even damage, and extends the service life.

[0048] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] A stable and anti-collapse sunshade curtain includes a guide rail 1 and a curtain device;

[0052] Two guide rails 1 are arranged side by side, and at least one set of curtain devices is slidably installed between the two guide rails 1. The curtain device includes a curtain 2, a rotating shaft assembly 3, a wire harness assembly 4, a moving assembly 5, and a support rod 6.

[0053] The curtain 2 has a fixed end and a movable end along its length. The fixed end of the curtain 2 is fixed to the rotating shaft assembly 3, and the movable end of the curtain 2 is fixed to the movable assembly 5. The wire harness assembly 4 is connected between the rotating shaft assembly 3 and the movable assembly 5.

[0054] Two guide rails 1 are symmetrically fixed at one end on the same side with fixed seats 7. The rotating shaft assembly 3 is rotatably installed between the two fixed seats 7. The fabric support rod 6 is fixedly installed between the two fixed seats 7. The fabric support rod 6 is located close to the rotating shaft assembly 3, and the outer surface of the fabric support rod 6 contacts the inner fabric surface of the curtain 2 to lift the curtain 2.

[0055] The moving component 5 is slidably mounted on the two guide rails 1. The moving component 5 includes a moving rod 51 and a slider 52. The slider 52 is fixedly mounted at both ends of the moving rod 51. The slider 52 includes an inner fixing part 521 and an outer guiding part 522.

[0056] The inner fixing part 521 is fixedly connected to the moving rod 51 and the moving end of the curtain 2. The outer guide part 522 is driven along the guide groove of the guide rail 1. The outer guide part 522 is provided with an upwardly protruding guide rail spring piece 5221, and the guide rail spring piece 5221 abuts against the groove surface of the guide groove.

[0057] Under the action of external force, the moving rod 51 moves closer to or further away from the rotating shaft assembly 3 along the direction of the guide rail 1 via the slider 52. The movement of the moving rod 51 drives the rotating shaft assembly 3 to rotate through the wire harness assembly 4. The curtain 2 can be rolled around the outer circumference of the rotating shaft assembly 3 through the rotation of the rotating shaft assembly 3.

[0058] like Figure 1-10 As shown, this sunshade achieves opening and closing operations through the sliding cooperation between the guide rail 1 and the moving component 5: when the driver or passenger pushes the moving rod 51, the outer guide part 522 of the slider 52 slides along the guide groove of the guide rail 1, and the protruding guide rail spring 5221 continuously presses against the groove surface, generating stable friction through elastic pressure, ensuring that the slider 52 can be accurately stopped at any position, and avoiding displacement when the vehicle is bumpy.

[0059] Importantly, during the unfolding of the curtain 2, the support rod 6, fixed between the two fixed seats 7, is in close contact with the inner fabric of the curtain 2. The support force of the rod counteracts the weight of the fabric, preventing the middle area between the rotating shaft assembly 3 and the support rod 6 from collapsing. The rotating shaft assembly 3 is fixed to one side of the skylight through the fixed seat 7. The fixed end of the curtain 2 rotates with the rotating shaft to achieve roll-up, while the moving end moves synchronously with the moving rod 51. The wire harness assembly 4 connects the rotating shaft assembly 3 and the moving assembly 5, which not only achieves synchronous movement of the two, but also ensures the tension balance during the unfolding and roll-up of the curtain 2, avoiding fabric wrinkles.

[0060] Compared to traditional designs, this sunshade has significant advantages, including the following beneficial effects:

[0061] 1. Precise and stable stopping: The elastic friction structure of the guide rail spring 5221 solves the positioning failure problem after the wear of traditional brake pads, and can be stably stopped at any position within the unfolded range, adapting to the sunshade needs of different sunlight angles;

[0062] 2. Anti-collapse and durable: The rigid support of the support rod 6, combined with the high-strength curtain fabric 2, improves the flatness after unfolding, reduces the accident rate of unsmooth rewinding or even damage, and extends the service life.

[0063] 3. Quiet and reliable: The close fit between the slider 52 and the guide rail 1 reduces gap shaking during bumps. Combined with the tension adjustment of the wiring harness assembly 4, it effectively eliminates abnormal noise and improves the quietness of the vehicle interior.

[0064] To further explain, the movable rod 51 includes a movable rod mounting sub-part 511;

[0065] The movable rod mounting sub-part 511 includes a positioning groove 5111 and two mounting grooves 5112, wherein the groove openings of the positioning groove 5111 and the two mounting grooves 5112 are arranged in opposite directions;

[0066] The inner fixing part 521 includes a positioning sub-part 5211 and two mounting sub-parts 5212. The positioning sub-part 5211 is located on both sides of the two mounting sub-parts 5212. The two mounting sub-parts 5212 are provided with upwardly protruding mounting springs 5213, and the mounting springs 5213 abut against the groove surface of the mounting groove 5112.

[0067] The positioning sub-part 5211 is installed inside the positioning groove 5111, and the two mounting sub-parts 5212 are respectively installed inside the two mounting grooves 5112.

[0068] like Figure 8-9As shown, the moving rod mounting sub-part 511 of the moving rod 51 includes a positioning groove 5111 and two mounting grooves 5112, and the groove openings of the positioning groove 5111 and the mounting grooves 5112 are opposite in direction, forming a bidirectional limiting structure; the positioning sub-part 5211 of the outer guide part 522 is embedded in the positioning groove 5111 to achieve precise lateral positioning and prevent the slider 52 from shifting along the width direction of the guide rail 1; the two mounting sub-parts 5212 are respectively embedded in the two mounting grooves 5112, and the protruding mounting spring piece 5213 on its surface continuously presses against the groove surface of the mounting groove 5112, generating multi-directional friction force through elastic pressure. When the moving rod 51 slides under force, the cooperation between the positioning sub-part 5211 and the positioning groove 5111 ensures that the sliding trajectory does not deviate. The tight contact between the mounting spring 5213 and the mounting groove 5112 enhances the overall braking effect. Together with the original guide rail spring 5221, it makes the stopping accuracy of the slider 52 at any position higher. At the same time, the bidirectional slot design, combined with the matching structure of the sub-part and the slot, further constrains the lateral swaying of the curtain 2 when it is unfolded and rolled up, ensuring that the transmission of the wire harness assembly 4 to the rotating shaft assembly 3 is more stable, and avoiding uneven tension of the curtain 2 caused by the deviation of the slider 52.

[0069] Furthermore, the movable rod 51 also includes a curtain mounting sub-part 512, which is disposed on one side of the movable rod mounting sub-part 511, and the movable rod mounting sub-part 511 and the curtain mounting sub-part 512 are integrally formed.

[0070] The curtain mounting section 512 is provided with a limiting groove 5121;

[0071] The moving component 5 also includes a pressing adhesive strip 53, which is pressed above the curtain 2 and pressed into the limiting groove 5121.

[0072] like Figure 6 and 8 As shown, a curtain mounting sub-part 512 is integrally formed on one side of the moving rod mounting sub-part 511 of the moving rod 51, with a limiting groove 5121 formed thereon. The pressing adhesive strip 53 of the moving assembly 5 presses on the screen 2 and is installed in the limiting groove 5121. When the screen 2 unfolds or retracts, the pressing adhesive strip 53 firmly fixes the edge of the screen 2 in the limiting groove 5121, preventing the screen 2 from deviating from the preset trajectory during movement. The integrally formed moving rod mounting sub-part 511 and curtain mounting sub-part 512 ensure structural strength and make the force on both more even. The curtain mounting sub-part 512 cooperates with the moving rod mounting sub-part 511 to further constrain the screen 2. Combined with the previous positioning and installation structure, this makes the screen 2 run more smoothly and avoids wrinkles or jamming caused by loose edges.

[0073] To further explain, the rotating shaft assembly 3 includes a rotating tube 31, a rotating shaft 32, a rotating bushing 33, a spring 34, and an anti-rotation terminal 35;

[0074] The wire harness assembly 4 includes a winding seat 41, a wire harness 42, and a take-up reel 43;

[0075] The outer guide portion 522 is also provided with a wire harness fixing portion 5222;

[0076] The inner sleeve of the rotating shaft 32 is embedded inside the rotating tube 31. The anti-rotation terminal 35 and the rotating shaft sleeve 33 are respectively fixedly installed at one end of the rotating shaft 32. The two ends of the spring 34 are respectively connected to the anti-rotation terminal 35 and the rotating shaft sleeve 33. The rotating shaft sleeve 33 is exposed outside the rotating shaft 32 and is fixedly installed at the center of the take-up reel 43.

[0077] The winding seat 41 is fixedly installed on the guide rail 1, and a winding wheel 44 is provided on the winding seat 41;

[0078] One end of the wire harness 42 is fixedly installed on the wire harness fixing part 5222, the middle section of the wire harness 42 is wound on the winding wheel 44, and the other end of the wire harness 42 is fixedly installed on the take-up wheel 43.

[0079] like Figure 6-9 As shown, when an external force pushes the moving component 5 to move the moving end of the curtain 2, the wire harness fixing part 5222 of the outer guide part 522 will simultaneously pull the wire harness 42. The winding wheel 44, which is wound around the winding seat 41 in the middle section of the wire harness 42, slides along the winding wheel 44 under the action of the pulling force, thereby driving the take-up wheel 43 connected to the other end of the wire harness 42 to rotate.

[0080] A rotating bushing 33 is fixedly mounted at the center of the take-up reel 43. The rotating bushing 33 rotates together with the take-up reel 43, and is exposed outside the rotating shaft 32 and connected to one end of the spring 34. The other end of the spring 34 is connected to an anti-rotation terminal 35 fixed to one end of the rotating shaft 32. Therefore, when the rotating bushing 33 rotates, it will twist the spring 34 to store torque. At the same time, the inner sleeve of the rotating shaft 32 is embedded inside the rotating tube 31, providing stable support for the entire rotating shaft assembly 3, while the anti-rotation terminal 35 restricts the rotation of the rotating shaft 32, ensuring that the spring 34 can stably store torque.

[0081] When the external force is removed, the spring 34 releases the stored torque, causing the rotating bushing 33 and the take-up reel 43 to rotate in the opposite direction. The take-up reel 43 tightens the wire harness 42, and the wire harness 42 is guided by the winding wheel 44 to pull the wire harness fixing part 5222, thereby resetting the moving component 5 and the curtain 2. During this process, the various components work together to ensure the smooth unfolding and rewinding of the curtain 2.

[0082] To further explain, the wire harness assembly 4 also includes an auxiliary strip 45;

[0083] The bottom of the outer guide portion 522 is provided with a barb 5223, the barb 5223 protrudes from the bottom of the outer guide portion 522, one end of the auxiliary belt 45 is provided with a hook hole, the barb 5223 passes through the hook hole, and the other end of the auxiliary belt 45 is fixed to the rotating tube 31.

[0084] like Figure 10 As shown, when an external force pushes the moving component 5 to move the moving end of the curtain 2, the wire harness fixing part 5222 of the outer guide part 522 simultaneously pulls the wire harness 42. At the same time, the barb 5223 at the bottom of the outer guide part 522 also drives the auxiliary belt 45. One end of the auxiliary belt 45 is connected to the barb 5223 through a hook hole, and the other end is fixed to the rotating tube 31. Therefore, when the moving component 5 moves, the auxiliary belt 45 and the wire harness 42 work together to drive the rotating shaft assembly 4 to rotate synchronously.

[0085] To further explain, there are two curtain devices, which are symmetrically arranged on the two guide rails 1. Under the action of external force, the two curtain devices can be arranged closer to or further apart from each other.

[0086] like Figure 1-2 As shown, the two curtain devices can be operated individually or simultaneously, and the shading range can be flexibly adjusted according to the position and intensity of sunlight. For example, only one side of the curtain 2 can be opened to block part of the area, so as to meet the personalized needs of different drivers and passengers.

[0087] Further explanation includes the curved trim panel 8 and the guide rail trim panel 9;

[0088] The curved decorative panel 8 is installed on the movable end of the curtain 2, and the curved decorative panel 8 is fixedly installed on the fixed base 7. The curved decorative panel 8 is used to cover the fixed base 7 and the rotating shaft assembly 3.

[0089] The guide rail panel 9 is installed on both sides of the curtain 2, and both ends of the guide rail panel 9 are fixedly installed on the fixing base 7 respectively. The guide rail panel 9 is used to cover the guide rail 1, the wire harness assembly 4 and the slider 52.

[0090] like Figure 2As shown, the curved trim panel 8 and the guide rail trim panel 9 offer several advantages. First, enhanced protection: the curved trim panel 8 effectively blocks dust and debris from entering the mounting base 7 and the rotating shaft assembly 3, preventing these impurities from affecting the smoothness of the shaft's rotation; the guide rail trim panel 9 protects the guide rail 1, wiring harness assembly 4, and slider 52 from external interference, reducing malfunctions such as jamming caused by foreign objects and extending the service life of each component. Second, improved aesthetics: these two trim panels cover previously exposed functional components, making the interior of the sunroof area cleaner and more unified, enhancing the overall aesthetics of the car and improving the visual experience for passengers. Third, reduced noise: the trim panels can, to some extent, block the sound generated by the slider 52 sliding on the guide rail 1 and the operation of the wiring harness assembly 4, further reducing interior noise and creating a quieter driving environment. Fourth, a more stable structure: the guide rail trim panel 9, fixed at both ends to the mounting base 7, also provides some auxiliary fixation to the guide rail 1, enhancing the overall structural stability of the sunshade.

[0091] To further explain, a handle 10 is provided at the center of the outer end of the movable rod 51.

[0092] like Figure 2 As shown, the handle 10 makes opening and closing the curtain convenient and reliable.

[0093] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
