Description

Technical Field

[0001] This invention relates to a sunshade curtain, and more particularly to a quick-release structure for the connection of the sunshade curtain. Background Technology

[0002] Sunshade curtains are tools used to block sunlight on vehicles. The fabric of a typical sunshade curtain is rolled up on a roller, which rotates and is connected to a connecting shaft. The connecting shaft is equipped with a coil spring, which allows the curtain to automatically roll up onto the roller after being unlocked.

[0003] Generally, each sunshade has a curtain, and one sunshade corresponds to one window. For some large vehicles, there may be multiple identical windows on one side, resulting in gaps between adjacent sunshades, which greatly affects the aesthetics.

[0004] An earlier patent of the applicant, CN215153843U, disclosed a splicable sunshade curtain. By setting easily removable cover plates in the gaps between the individual sunshade curtain units, the sunshade curtain has good integrity after installation and will not leave large gaps that affect the appearance of the product.

[0005] However, the original cover plates were installed using a snap-fit ​​connection. Once installed, this structure made it difficult to remove the cover plates, and the snap-fit ​​connection was prone to loosening, causing abnormal noises. Therefore, it was necessary to improve the design. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a quick-release structure for the connection of a sunshade curtain, which is convenient for both installation and disassembly, and relies on elasticity to tighten the curtain box, making it less prone to loosening.

[0007] The technical solution adopted by this invention to solve its technical problem is: a quick-disassembly structure for the connection of a sunshade curtain, comprising several individual units, each unit including a curtain box, the two ends of which are provided with downwardly extending guide rails, characterized in that: the two ends of the curtain box are provided with latches, the latches are two in number, and a cover plate is also provided, the back of the cover plate has an upper latch and a lower latch, the upper latch includes a latching block, one end of the latching block is connected to the cover plate, there is a gap between the latching block and the cover plate, the gap distance is equal to the outer shell thickness of the curtain box, the lower latch includes a protrusion, the end of the protrusion has an outwardly protruding blocking block, and the outer ring of the cover plate of the lower latch is provided with a strip groove, the strip groove surrounds the lower latch on three sides. During installation, first insert the upper clip of the cover plate into the upper slot to clamp the curtain box shell. Then insert the lower clip into the lower slot. During insertion, the presence of the blocking block will cause the lower clip to experience outward resistance, pushing the cover plate outward. Press this protruding portion of the cover plate back in by hand, and the blocking block will engage in the lower slot. At this point, the pressed-in cover plate will slightly deform and bulge due to the pressure of the blocking block, completing the cover plate installation. For disassembly, simply press the slightly bulging portion of the cover plate inward. This will shift the position of the blocking block, releasing the contact with the slot, allowing the lower half of the cover plate to be pulled out. Then pull the cover plate down to remove the upper clip, completing the cover plate removal. This design is convenient for both installation and disassembly, and the added groove allows the cover plate to elastically hold the curtain box in place, preventing it from loosening.

[0008] In the above technical solution, preferably, one of the bayonet slots is located on the front of the housing, and the other bayonet slot is located on the bottom of the housing.

[0009] In the above technical solution, preferably, the width of the blocking block gradually increases from top to bottom.

[0010] In the above technical solution, preferably, the protrusion is hollow.

[0011] In the above technical solution, preferably, the lower bayonet is provided with an inwardly facing flange, and the outer wall of the protrusion contacts the flange.

[0012] The beneficial effects of this invention are as follows: During installation, first insert the upper clip of the cover plate into the upper slot to clamp the curtain box shell. Then, insert the lower clip into the lower slot. During insertion, the presence of the blocking block causes the lower clip to experience outward resistance, which pushes the cover plate outward. Then, press this pushed-out portion of the cover plate back in by hand, and the blocking block engages in the lower slot. At this point, the pressed-in cover plate will slightly deform and bulge due to the pressure of the blocking block, thus completing the installation of the cover plate. For disassembly, simply press the slightly bulging portion of the cover plate inward, causing the blocking block to shift and disengage from the slot, allowing the lower half of the cover plate to be pulled out. Then, pull the cover plate down to remove the upper clip, thus completing the disassembly of the cover plate. This solution is convenient for both installation and disassembly, and the addition of the slot allows the cover plate to elastically hold the curtain box in place, preventing it from loosening.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0018] See Figures 1 to 4 A quick-release structure for the connection of a sunshade curtain includes several individual units 1, each unit 1 including a curtain box 11. The curtain box 11 has downwardly extending guide rails 13 at both ends, and two latches 12 at both ends. One latch is located on the front of the outer casing, and the other latch is located on the bottom of the outer casing.

[0019] It also includes a cover plate 2, the back of which has an upper clip 21 and a lower clip 22.

[0020] The upper clip 21 includes a clip 211, one end of which is connected to the cover plate 2. There is a gap between the clip 211 and the cover plate 2, and the distance of the gap is equal to the outer shell thickness of the curtain box.

[0021] The lower clip 22 includes a hollow protrusion 221. The end of the protrusion 221 has an outwardly protruding blocking block 222, the width of which gradually increases from top to bottom. A strip groove 23 is provided on the outer ring cover plate 2 of the lower clip 22, surrounding the lower clip 22 on three sides. The lower latch 12 has an inwardly facing flange 1a, and the outer wall of the protrusion contacts the flange.

[0022] During installation, first insert the upper clip of the cover plate into the upper slot to clamp the curtain box shell. Then insert the lower clip into the lower slot. During insertion, the presence of the blocking block will cause the lower clip to experience outward resistance, pushing the cover plate outward. Press this protruding portion of the cover plate back in by hand, and the blocking block will engage in the lower slot. At this point, the pressed-in cover plate will slightly deform and bulge due to the pressure of the blocking block, completing the cover plate installation. For disassembly, simply press the slightly bulging portion of the cover plate inward. This will shift the position of the blocking block, releasing the contact with the slot, allowing the lower half of the cover plate to be pulled out. Then pull the cover plate down to remove the upper clip, completing the cover plate removal. This design is convenient for both installation and disassembly, and the added groove allows the cover plate to elastically hold the curtain box in place, preventing it from loosening.
