Description

Technical Field

[0001] This utility model relates to the field of car interior curtains, specifically a quick-install car interior curtain. Background Technology

[0002] Car curtains are devices installed inside a vehicle, primarily for blocking light, insulating heat, and protecting privacy. They are typically made of fabric and can be installed above car windows or doors. They are available in a variety of colors and patterns and can be customized to the owner's preferences.

[0003] In the prior art, such as in publication number CN212637116U, a car curtain is disclosed, which includes a magnetic rail, several hooks, and a blackout curtain; the magnetic rail is elongated and has a groove running through it along its length; the hooks include a sliding part and a holding part, the sliding part is slidably disposed in the groove, and the holding part is fixedly connected to the sliding part and extends out of the groove; the blackout curtain is hung on the holding part;

[0004] While the aforementioned patent allows for the installation of car curtains without altering the vehicle's structure—reducing the professional requirements for installation while ensuring the vehicle's strength—installation of the interior curtains on the windows presents limitations. Some car models lack magnetic edging in their window sashes, leading to installation difficulties. Using a fixed structure for installation can damage the original window structure, causing the curtain track to wobble and move when the vehicle is open. Furthermore, the curtain cannot be adjusted to accommodate the required light penetration when partial light transmission is needed. Therefore, this invention proposes a quick-installation car curtain to address these issues. Utility Model Content

[0005] To address the shortcomings of existing technologies, when installing curtains on car windows, the lack of magnetic edging in some models limits installation options. Using fixed structures for installation can damage the original window structure. Furthermore, the curtain track shakes when the vehicle is open, causing the curtain to move. Additionally, the curtain cannot be adjusted to accommodate the required light penetration when specific areas need light. This invention proposes a quick-install car interior curtain.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A quick-install car interior curtain of this utility model includes a square frame; several upper buckles are snapped onto the top of the square frame, and several lower buckles are provided at the bottom of the square frame; an arc-shaped H-beam is attached to the top inner surface of the square frame; the arc-shaped H-beam has an H-shaped cross-section and sliding grooves on both sides; several pulleys are slidably connected inside the sliding grooves; a U-shaped frame is provided on the side of the pulleys; the curtain fabric is connected to the bottom of the U-shaped frame; several fixing holes are equidistantly provided on the top inner surface of the sliding grooves; springs are installed inside the fixing holes; one end of the springs is connected to a limiting bead; a horizontal groove is provided on the bottom inner surface of the square frame; a limiting rod is provided inside the horizontal groove; the limiting rod penetrates the bottom end of the curtain fabric.

[0007] Preferably, the upper buckle has a narrowed S-shaped structure and the width of the right opening is adapted to the top of the square frame, and the width of the left opening of the upper buckle is less than the thickness of the window sealant layer.

[0008] Preferably, the bottom of the lower buckle is provided with an adhesive layer, and the depth of the top groove of the lower buckle matches the thickness of the bottom of the square frame.

[0009] Preferably, the diameter of the limiting bead is greater than the width of the fixing hole opening and the bottom is hemispherical, and the preload of the spring is greater than the squeezing resistance when the pulley slides.

[0010] Preferably, the inner wall of the groove is coated with a self-lubricating coating, and the rolling surface of the pulley and the contact surface of the groove have an arc-shaped complementary structure.

[0011] Preferably, the material of the arc-shaped H-beam frame is elastic nylon composite material, and a binding strap is provided on one side of the curtain fabric with Velcro at the end of the binding strap.

[0012] The advantages of this utility model are:

[0013] 1. This utility model achieves the function of non-destructive and rapid installation of the car window sealant layer through the narrow S-shaped structure design of the upper buckle. After the narrow side of the left opening of the upper buckle is inserted into the sealant gap, the wide side of the right opening is inserted into the top of the square frame. The elastic deformation of the S-shaped buckle adapts to different sealant layer thicknesses, solving the problem of dependence on the car window edging material of traditional magnetic curtains and improving the universality of installation.

[0014] 2. This utility model achieves stepless adjustment of the curtain opening and closing position through the sliding limit structure design of the arc-shaped H-shaped beam and pulley. When the pulley slides, it squeezes the limit bead to compress the spring and disengage it from the fixing hole. When it is released, the spring pushes the limit bead to embed it into the adjacent fixing hole. The dynamic engagement and release of the spring and limit bead solves the problem that traditional curtains cannot be fixed after sliding, and improves the efficiency of light transmission range adjustment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1-4 As shown, a quick-install car interior curtain includes a square frame 1; several upper buckles 2 are snapped onto the top of the square frame 1, several lower buckles 3 are provided at the bottom of the square frame 1, an arc-shaped H-beam 4 is attached to the inner top surface of the square frame 1, the arc-shaped H-beam 4 has an H-shaped cross-section and sliding grooves 5 on both sides, several pulleys 6 are slidably connected inside the sliding grooves 5, a U-shaped frame 7 is provided on the side of the pulleys 6, the bottom of the U-shaped frame 7 is connected to the curtain fabric 8, several fixing holes 9 are equidistantly provided on the inner top surface of the sliding grooves 5, springs 10 are provided inside the fixing holes 9, one end of the springs 10 is connected to a limiting bead 11; a horizontal groove 12 is provided on the inner bottom surface of the square frame 1, a limiting rod 13 is provided inside the horizontal groove 12, and the limiting rod 13 penetrates the bottom end of the curtain fabric 8.

[0023] During operation, the narrow left opening of the upper buckle 2 is inserted into the gap of the sealant layer along the upper edge of the window. The elastic deformation of the S-shaped structure presses the top of the square frame 1 into the wide right opening to complete the snap-fit. The adhesive layer at the bottom of the lower buckle 3 is pasted to the lower edge of the window, and the bottom of the square frame 1 is embedded in the slot of the lower buckle 3. When the sliding U-shaped frame 7 drives the pulley 6 to move along the slide groove 5, the pulley 6 contacts the limiting bead 11 and compresses the spring 10 to disengage from the fixing hole 9. After the sliding stops, the spring 10 rebounds and the limiting bead 11 is embedded into the adjacent fixing hole 9 to lock the position of the curtain 8. The limiting rod 13 guides the bottom of the curtain 8 to move laterally in the horizontal groove 12 to keep it flat. The elastic deformation of the buckle and the dynamic engagement of the limiting bead 11 work together to achieve quick and non-destructive installation and fixation of the curtain 8 in any position, solving the limitations of traditional magnetic installation.

[0024] Furthermore, the upper buckle 2 has a narrowed S-shaped structure and the width of the right opening is adapted to the top of the square frame 1, while the width of the left opening of the upper buckle 2 is less than the thickness of the window sealant layer.

[0025] During operation, the left opening of the upper clip 2 is designed to be a narrow slit of 3-5mm to match the thickness of the window sealant layer, while the right opening precisely engages with the 8-10mm thickness of the top of the square frame 1. During installation, the S-shaped structure of the elastic nylon material generates clamping force through deformation, preventing the frame from falling off. The S-shaped double opening design increases the installation error tolerance, adapts to the sealant layer thickness of most car models, and significantly enhances installation stability.

[0026] Furthermore, an adhesive layer is provided at the bottom of the lower buckle 3, and the depth of the top groove of the lower buckle 3 matches the thickness of the bottom of the square frame 1;

[0027] During operation, the bottom of the lower clip 3 is coated with 3M double-sided adhesive. The depth of the clip groove is set to 1.2 times the thickness of the bottom of the square frame 1. During installation, pressing down on the bottom of the frame creates an interference fit between the inner wall of the clip groove and the frame. Combined with the adhesive layer, this provides double fixation. The interference fit and the adhesive layer work together to generate 12 N / cm. 2 With its strong binding force, the frame displacement is less than 0.5mm under bumpy vehicle conditions, solving the problem of curtain swaying.

[0028] Furthermore, the diameter of the limiting bead 11 is larger than the opening width of the fixing hole 9 and the bottom is hemispherical, and the preload of the spring 10 is greater than the squeezing resistance when the pulley 6 slides.

[0029] During operation, the limit bead 11 is made of stainless steel ball, and the spring 10 is made of silicon manganese steel wire; the sliding pulley 6 compresses the spring 10 to disengage the limit bead 11 from the fixing hole 9. After being released, the spring 10 generates a rebound force to ensure that the limit bead 11 is reset. The precise matching of the limit bead 11 with the hole size reduces the adjustment operation force, and the curtain 8 can be accurately positioned with one hand.

[0030] Furthermore, the inner wall of the slide groove 5 is coated with a self-lubricating coating, and the rolling surface of the pulley 6 and the contact surface of the slide groove 5 have an arc-shaped complementary structure.

[0031] During operation, the inner wall of the slide groove 5 is coated with polytetrafluoroethylene, and the rolling surface of the pulley 6 is machined into an arc to form a rolling friction pair with the arc surface of the slide groove 5.

[0032] Furthermore, the material of the arc-shaped H-beam frame 4 is elastic nylon composite material, and a binding strap 14 is provided on one side of the curtain 8 and a Velcro is provided at the end of the binding strap 14.

[0033] During operation, the arc-shaped H-beam frame 4 is made of PA66+30% glass fiber composite material with a bending modulus of 8500MPa; after the curtain fabric 8 is rolled up, it is wrapped by the binding strap 14. The high modulus material makes the deformation of the beam frame less than 0.3mm in an environment of -30℃~80℃. The binding strap 12 system realizes the volume compression rate of the curtain fabric 8 and reduces the storage space occupied.

[0034] Working principle: The upper buckle 2 is inserted into the gap of the window sealant layer through the S-shaped narrow opening and then elastically snaps into the top of the square frame 1. The lower buckle 3 is fixed to the lower edge of the window with the adhesive layer. When the pulley 6 slides along the groove 5 of the arc-shaped H-shaped beam 4, it squeezes the limiting bead 11 and compresses the spring 10 to disengage from the fixing hole 9. After the curtain 8 moves to the target position with the U-shaped frame 7, the spring 10 rebounds and pushes the limiting bead 11 into the adjacent fixing hole 9 to lock the opening angle of the curtain 8. The limiting rod 13 guides the bottom of the curtain 8 to move laterally in the horizontal groove 12 to keep it flat. The binding strap 14 is rolled up and fixed by Velcro to fix the idle curtain 8.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
