Description of the Invention: [Technical Field] The present invention relates to a sunshade device, and more particularly to a sunshade device having a retracting function in which a cord can be automatically wound up. [Prior Art] Referring to Figures 1 and 2, a conventional sunshade device basically includes two left and right symmetrical end seats 11, a housing 12 fixedly mounted between the end seats u, and a rotatably mounted on the housing A sunshade unit 丨3 between the end seats U, and a retracting mechanism 14 for imparting a retracting function to the sunshade unit 13. The sunshade unit 13 includes a reel 131 that is disposed in a passage 121 of the outer casing 12, a cord 132 that is wound around the reel 131 and whose unfolded end is extended by a slot 22 of the outer casing 12, and a curtain 132 A positioning member 133 mounted on the unfolding end of the cord 132, and two linking members 134 that are sleeved on the two axial ends of the reel 131. The reeling machine 14 includes a mandrel 14 and a spiral elastic 142 which are disposed in one of the reels 1 of the reel and are fixed to one of the end seats u. When the cyanine 142 is installed between the core & 141 and one of the linking members 134 in a manner of accumulating the retracting force, the unfolding end of the retracting force 嶋 132 of the helical magazine 142 is pulled away from the outer casing 12, and the positioning is performed. When the piece 133 is hooked in place, the curtain U2 can be maintained in the deployed position, and during the unfolding (four) 132, the end of the coil spring 142 will rotate with the linkage #134 and the reel (3) and accumulate the retracting force. Therefore, when the positioning member (3) is disengaged from the fishing position, the screw 142 releases the accumulated volume to recover the 201126054 position force, and thus the reel 131 is reversed, thereby causing the curtain 132 to rewind the reel 131. on. It is known that although the sunshade 1 can reel the cord 132, the mandrel 141 and the coil spring 142 which provide the retracting force are mounted in the shaft 135 of the reel 131 having a small space, and are limited by the installation space. The retracting mechanism 14 of the sunshade 1 not only has small parts and is inconvenient to assemble, but the wire diameter of the coil spring 142 cannot be too large, so the winding force is poor.

The connecting seat 22 is mounted on one end of the outer casing 20 by two coupling pins 25, and has a card wall 221 inserted in the clamping slot 216 of the first end seat 21, and a a protruding block 222 protruding from the card wall 221 and being latched in the latching hole 218 of the first end seat 21, the card wall 201126054 221 having a base 215 facing the first end seat 21 The card slot 223. The end cap 23 has a cover wall 231 sized to cooperate with the first end wall 211, and a cover ring wall 232 protruding from the periphery of the cover wall 231 toward the first end seat 21, the cover wall 231 and the cover ring wall 232 define an accommodating space 233 for accommodating the retracting mechanism 4. The second end cover 24 is coupled to the other end of the outer casing 20 by two other coupling pins 25, and has a fulcrum hole 241 axially corresponding to the rotating support hole 213. The sunshade unit 3 of the present embodiment includes a reel 31 mounted in the passage 201 of the outer casing 2, a cord 32 wound on the reel 31, and a first linkage 33 coupled in conjunction with the reel 31, a collar 34 for rotatably erecting the first linking member 33 on the rotating branch hole 213 of the first end seat 2, and a first portion coupled to the reel 31 and erected on the fulcrum hole 241 Two linkages 35. The cord 32 has a flared end 321 that projects out of the slot 204 of the outer casing 2, and the shade unit 3 further includes a hanger 36 mounted to the flared end 321 . The first linking member 33 has a coupling portion 331 which is inserted into one of the shafts 311 of the reel 31, a connecting card portion 332 having a flat rod shape, and a connecting portion 331 and the interlocking card portion 332. And the rotating branch portion 333 of the collar 34 is disposed in the receiving empty door 233 of the mounting unit 2 and the receiving force is applied to the sunshade unit 3, and the retracting mechanism* includes - a torsion runner 41 that is rotatable between the first end wall 211 and the outer cover wall 231, a linkage bracket 42 that interlocks the torsion runner 41 and the first linkage member, and a rotatably sleeved sleeve a retracting wheel 43 on the wheel mount mounting rod 201126054 214 of the first end seat 21, and a fixed torsion spring 44 which is wound on the retracting wheel 43 and which is biased to the torsion runner 41. The wheel 41 has two left and right spaced wheel walls 411, a circumferential wall 412 connecting the wheel walls 411 and surrounding the center of rotation of the reel 31, and an axially extending shaft tube wall 413 having A interlocking card slot 414 is located on the outer side, and the circumferential wall 412 has a slot 415. The interlocking card holder 42 has an engaging wall 422 that defines a φ engaging hole 421 for engaging the interlocking card portion 332 of the first linking member 33, and a card protrudes from the engaging wall 42 The interlocking block 423 in the interlocking slot 414 of the torsion wheel 41 has a base wall 431 and a hollow shaft wall for the wheel hub mounting rod 214 432. The fixed torsion spring 44 has a retracting end 441 that is torqueably wound on the shaft tube wall 432, and an acting end 442 that is inserted into the slot 415 of the torsion wheel 41. When the sunshade device of the embodiment is in the folding position, the curtain 32 is retracted on the reel 31. At this time, the fixed torque spring is mostly wound around the shaft wall 432 of the undercut wheel 43. ±, when the sunshade device is to be switched to the deployed position shown in Fig. 3, the pendant % of the sunshade unit 3 is grasped, and the retracting force of the constant spring spring 44 is overcome, and the unfolded end 32 of the cord 32 is gradually formed. The casing 20 is pulled away from the outer casing 20, and during the unfolding of the curtain 32, the reel will drive the first and second linking members 33, 35 to rotate synchronously, and thus the linkage card 42 and the torsion runner 41 of the retracting mechanism 4 are driven. Simultaneously rotating, the gradual winding of the fixed-torque springs 44 originally wound up in the accommodating wheel 43 is received by the torque runner 41, and f is retracted to receive the restoring force. When the force of the deployment of the curtain 32 is levied, when the lens is lost, the fixed torque spring 44 that originally accumulated the torque will gradually rewind onto the detaching wheel 43 at 201126054, thereby achieving the automatic retraction of the sunshade unit 3. purpose. It is worth mentioning that the design of the sunshade device of the present invention is not only structurally innovative, but also can be installed on the outside of the first end seat 21 of the body unit 2 by the retractor 4 that generates the restoring force. It is not limited by the internal space of the reel 31. Therefore, it is not only convenient to install, but also a torsion spring 44 having a large width and a long torque can be used to generate the torsion force to ensure that the sunshade device can maintain a better retraction for a long time. The sunshade device of the present invention also has the advantages of convenient assembly and better retracting force. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are all It is still within the scope of the invention patent.
