Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a sunshade assembly and a vehicle. Background Technology

[0002] Car sunshades effectively block direct sunlight. Currently, some car sunshades use a pull cord as the transmission medium. One end of the cord connects to a slider on a pull rod. After the cord changes direction via a roller, the other end connects to a spool on a roller. In manual sunshades, pushing the pull rod moves the slider, which in turn moves the roller via the cord. In electric sunshades, a motor drives the spool, which in turn moves the pull rod via a pull cord. The curtain has side strips that slide within guide rails on both sides, keeping the curtain taut along the length of the roller and preventing it from sagging. Together with the guide rails, roller, and spring assembly, this forms a complete sunshade retraction system.

[0003] Existing sunshade curtains have the following main shortcomings:

[0004] (1) In existing sunshade curtains, the connection and installation of the pull cord and slider is difficult, such as Figure 1 As shown, the iron core at one end of the pull rope is pressed into a slot in the opening of the slider in the vehicle height direction. During installation, because the slot is open in the vehicle height direction, the iron core can easily fall out. During operation, after the iron core falls out of the slot, it will rub against the guide rail, producing abnormal noise, or it may become stuck with the guide rail.

[0005] (2) In existing sunshade curtains, the pull cord is connected to the reel, such as... Figure 2 As shown, the iron core at one end of the pull rope is inserted into the open slot on one side of the spool. The pull rope is wound onto the spool along the spool groove on the same side as the slot. Because the iron core of the pull rope and the pull rope are installed on the same side of the spool, the pull rope is prone to detaching from the spool during installation, which can lead to the failure of the pull rope winding.

[0006] (3) In existing sunshade curtains, the curtain fabric has side strips on both sides, and the side strips slide within the side rails combined with the curtain fabric. At the end where the curtain fabric connects to the pull rod, the side strips are not connected to the slider. In manual sunshade curtains, such as Figure 3 As shown, when the pulling force of the pull rod on the curtain and side strip is oblique, the side strip is subjected to the tension of the curtain in the direction of movement, which increases the friction between the side strip and the guide rail. This results in high resistance in the side strip movement system, making it difficult to pull, prone to jamming, and may even cause the curtain to detach from the guide rail, rendering the sunshade curtain inoperable. Furthermore, during the assembly of the sunshade curtain, the curtain enters from the end of the guide rail, requiring manual adjustment of the side strip position and direction to allow the side strip and curtain to enter the guide rail, making installation complex.

[0055] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0056] In some embodiments of this application, such as Figure 4-7 As shown, a sunshade assembly 10 is provided, comprising:

[0057] Glass 11;

[0058] The drive assembly 12 includes a roller 121, a pull rod 122, and a drive mechanism 123. The roller 121 is fixed to the glass 11, and the pull rod 122 is spaced apart from the roller 121. The drive mechanism 123 is disposed on the pull rod 122 or the roller 121.

[0059] The slide rail assembly 13 includes a guide rail 131 and a slider 132. The guide rail 131 is fixed to the glass 11. The slider 132 includes a connected mounting portion 1323 and a sliding portion 1324. The mounting portion 1323 is fixed to the pull rod 122, and the sliding portion 1324 is slidably mounted in the guide rail 131. The portion of the sliding portion 1324 facing the glass 11 is the first portion 1321, and the portion of the sliding portion 1324 facing away from the glass 11 is the second portion 1322. A positioning portion 1325 is provided on the sliding portion 1324.

[0060] Curtain 14, one end of which is wound around the roller 121, and the other end of which is connected to the pull rod 122; two sides of the curtain 14 are disposed within the guide rail 131; and

[0061] The pulley assembly 15 includes a spool 151, a pulley 152, and a pull rope 153. The spool 151 is disposed at one end of the guide rail 131 near the spool 121, and the pulley 152 is disposed at the other end of the guide rail 131. One side of the pull rope 153 is wound around the spool 151, and the other side of the pull rope 153 is fixed to the positioning part 1325 after being reversed by the pulley 152.

[0062] The number of slide rail assemblies 13 and pulley assemblies 15 are both two, with the two slide rail assemblies 13 symmetrically arranged on both sides of the glass 11; the two pulley assemblies 15 are symmetrically arranged on both sides of the glass 11.

[0063] By providing a positioning part 1325 on the sliding part 1324 of the slider 132, the other side of the pull rope 153 is fixed to the positioning part 1325 of the slider 132 after being reversed by the pulley 152. This improves the reliability of the connection between the pull rope 153 and the slider 132, and prevents the part of the pull rope 153 connected to the sliding part 1324 of the slider 132 from falling off the sliding part 1324, which would cause the sunshade assembly 10 to jam or make abnormal noise.

[0064] In this embodiment, the material of the glass 11 is not limited, and it is usually inorganic glass, organic glass, or composite material; the material of the guide rail 131 is not limited, and it is usually plastic or metal.

[0065] Furthermore, in one embodiment, such as Figure 5-7As shown, the pull cord 153 includes a first end piece 1531 fixed to the sliding portion 1324, and the positioning portion 1325 includes a positioning member 1326, a wire mounting groove 1327, and a first groove 1328 communicating with the wire mounting groove 1327. The wire mounting groove 1327 is disposed on the surface of the second portion 1322 away from the glass 11, and the wire mounting groove 1327 is used to accommodate the pull cord 153 entering the sliding portion 1324. The first groove 1328 is disposed between the first portion 1321 and the second portion 1322, and the first groove 1328 is located at the end of the sliding portion 1324. The shape of the first groove 1328 matches the shape of the first end piece 1531, and the first end piece 1531 is embedded in the first groove 1328. The width of the first groove 1328 is greater than the width of the wire mounting groove 1327.

[0066] During installation, the pull cord 153 enters the sliding part 1324, passes through the positioning member 1326, and then enters the wiring groove 1327. Since the wiring groove 1327 is located on the surface of the second part 1322 away from the glass 11, the pull cord 153 can be pressed into the wiring groove 1327 from the surface of the second part 1322 away from the glass 11. The wiring groove 1327 communicates with the first groove 1328, which is located at the end of the sliding part 1324. The width of the first groove 1328 is greater than the width of the wiring groove 1327, allowing the pull cord 153 to enter... Insert the first groove 1328 and press the pull rope 153 into the wiring groove 1327 and the first groove 1328. At this time, the first end piece 1531 is located outside the end of the sliding part 1324. Then, pull the pull rope 153 from the other end, so that the first end piece 1531 is embedded in the first groove 1328, which improves the connection reliability between the pull rope 153 and the slider 132. The first end piece 1531 is limited by the first groove 1328 in the height direction of the vehicle, which solves the problem in the prior art that the end piece of the pull rope connected to the sliding part of the slider is easy to fall off in the height direction of the vehicle.

[0067] In one embodiment, there are multiple positioning elements 1326, which are arranged sequentially and at intervals along the arrangement path of the pull rope 153 on the sliding part 1324. By providing multiple positioning elements 1326, the connection reliability between the pull rope 153 and the slider 132 is further improved.

[0068] Furthermore, such as Figure 5-7As shown, the pull rope 153 entering the sliding part 1324 includes a first segment that enters the sliding part 1324 after turning along the pulley 152, a second segment disposed opposite to the first segment, and a connecting segment for connecting the first segment and the second segment. At least one positioning member 1326 is disposed in the first segment, and at least one positioning member 1326 is disposed in the connecting segment. By providing at least one positioning member 1326 in the first segment and the connecting segment respectively, the connection reliability between the pull rope 153 and the slider 132 is further improved.

[0069] In one embodiment, such as Figure 8 As shown, the pull rope 153 further includes a second end piece 1532 fixed to the reel 151. The reel 151 has a first side 1513 and a second side 1514 facing each other. The first side 1513 of the reel 151 is provided with a second groove 1511 that matches the shape of the second end piece 1532. The second end piece 1532 is fixed to the second groove 1511. The reel 151 is also provided with a winding groove 1512 for accommodating the pull rope 153. The pull rope 153 is wound from the second side 1514 of the reel 151 onto the winding groove 1512.

[0070] The second end piece 1532 is disposed in the second groove 1511 located on the first side 1513 of the spool 151. The pull rope 153 is wound from the second side 1514 of the spool 151 onto the winding groove 1512. The position of the second end piece 1532 is on a different side from the position where the pull rope 153 begins to wind on the winding groove 1512 of the spool 151. Compared with the prior art where the two are disposed on the same side, this enhances the fixing effect between the spool 151 and the pull rope 153, and solves the problem in the prior art where the end piece of the pull rope connected to the spool is easy to detach from the spool, resulting in the pull rope tangling failure.

[0071] In this embodiment, optionally, as Figure 9 As shown, the spool 151 is cylindrical, or, as... Figure 10 As shown, the spool 151 is conical.

[0072] In one embodiment, such as Figure 6 , 11 As shown in Figure 13, the sliding part 1324 is provided with a fixing member 1329 protruding from the surface of the second part 1322 away from the glass 11. Both sides of the curtain 14 are provided with edge strips 141. The edge strips 141 are provided with holes 1411 that cooperate with the fixing member 1329. The fixing member 1329 is fixed to the holes 1411.

[0073] The hole 1411 mates with the fixing member 1329, so that the edge strip 141 and the sliding part 1324 of the slider 132 are connected and slide together with the guide rail 131. At this time, as Figure 14 As shown, the force direction of the edge strip 141 is the same as that of the pull rod 122. The friction between the edge strip 141 and the guide rail 131 is small, and the motion system resistance of the edge strip 141 is small, making the edge strip 141 easy to pull.

[0074] In this embodiment, the edge strip 141 can be made of plastic materials such as TPV, TPE, and TPEE, or it can be made of steel strip or PDF. Preferably, the edge strip 141 is made of plastic. Plastic edge strips have advantages such as low coefficient of friction, easy roll-up and bending, and good flexibility, which can reduce the resistance of the curtain 14 during operation and improve the operational stability of the curtain 14 in the sunshade assembly 10.

[0075] In this embodiment, the fixing member 1329 further includes a connected side portion 13291 and a hook portion 13292, the side portion 13291 and the hook portion 13292 forming a hook groove 13293, the hook groove 13293 being fixed to the hole 1411. The hook groove 13293 of the fixing member 1329 engages with the hole 1411 of the edge strip 141, so that the edge strip 141, after being connected to the sliding portion 1324 of the slider 132, slides together with the guide rail 131.

[0076] In this embodiment, the number of fixing members 1329 is further multiplied, at least one of the fixing members 1329 has a hook groove 13293 facing away from the mounting portion 1323, and at least one of the fixing members 1329 has a hook groove 13293 facing the movement direction of the sliding portion 1324. This further reduces the friction between the edge strip 141 and the guide rail 131, making the edge strip 141 easier to pull.

[0077] Since the hook groove 13293 is fixed to the hole 1411, and the hook groove 13293 of at least one of the fixing members 1329 faces away from the mounting part 1323, the edge strip 141 can be prevented from being subjected to a force in the interval direction of the two guide rails 131; the hook groove 13293 of at least one of the fixing members 1329 faces the movement direction of the sliding part 1324. Since the sliding part 1324 is connected to the mounting part 1323 and the mounting part 1323 is fixed to the pull rod 122, the force on the edge strip 141 in the same direction as the pull rod 122 can be strengthened.

[0078] In this embodiment, the hole 1411 is further provided at one end of the edge strip 141 near the pull rod 122, so that the sliding part 1324 of the slider 132 can guide the edge strip 141 into the guide rail 131, thereby improving the ease of installation of the edge strip 141.

[0079] In one embodiment, the drive mechanism 123 is a manual drive mechanism or a motor drive mechanism, which can open and close the curtain 14 in both manual and automatic ways.

[0080] Furthermore, such as Figure 4 As shown, the manual drive mechanism is a handle 1231 mounted on the pull rod 122.

[0081] In addition, the present invention also provides a vehicle including the sunshade assembly 10 as described above.

[0082] The aforementioned vehicle, by using the sunshade assembly 10 as described above, improves the connection reliability between the pull cord 153 and the slider 132, avoiding jamming or abnormal noise caused by the end piece of the pull cord 153 connected to the sliding part 1324 of the slider 132 falling off; at the same time, it improves the connection reliability between the pull cord 153 and the spool 151, avoiding the pull cord 153 from detaching from the spool 151 due to the end piece of the pull cord 153 connected to the spool 151 falling off, thus causing the pull cord 153 to become entangled and fail, further reducing assembly difficulty and improving product lifespan; and it solves the problems of uneven operation and derailment of the curtain 14 and the side strip 141 caused by uneven force during operation, reducing the running resistance of the sunshade, improving stability during movement, and improving assembly efficiency.

[0083] It should be noted that, in this invention, if the glass 11 is an inorganic glass, examples include soda-lime glass (also known as soda-lime silicate glass), aluminosilicate glass, borosilicate glass, lithium aluminum silicate glass, alkali-free glass, and quartz glass. Soda-lime glass is particularly preferred among these. From the perspective of improving strength, the inorganic glass can also be a strengthened glass, which can be either chemically strengthened or physically strengthened.

[0084] If the glass 11 is plexiglass (resin), examples include polycarbonate resin, polystyrene resin, aromatic polyester resin, acrylic resin, polyester resin, polyarylate resin, condensation polymers of halogenated bisphenol A and ethylene glycol, urethane acrylate resin, and acrylic resin containing halogenated aryl groups. Among these, aromatic polycarbonate resins and other polycarbonate resins, as well as polymethyl methacrylate acrylic resins and other acrylic resins, are preferred; polycarbonate resins are more preferred; and bisphenol A polycarbonate resins are particularly preferred. Furthermore, two or more of the above resins may be used in combination.
