Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a sunshade, and more particularly to a semi-automatic sunshade that is mounted at a side window of a car and that can be automatically retracted. [Prior Art] Referring to Fig. 1, a conventional semi-automatic sunshade 1 comprises: a housing u having a hollow and top side having an opening 1U, a rotatably mounted in the housing n and having a retracting force The reel 12, a piece of cord 13 that is retractably wound around the periphery of the reel 12, a side strip 14 mounted on one of the unfolded ends 131 of the cord 13, and one spaced apart from the reel 12 for unfolding the rear curtain 13 The upper side strip 14 hooks the positioned hanging seat 15. In use, the user pulls the cord 3 out of the opening 111' of the shell and hooks the strip u to the hanger 15, positioning the curtain 13 in a deployed position. When the user releases the side strip W from the hook of the holder n and releases the curtain 13, the curtain 13 is wound up by the spool 12 at an extremely fast speed. Although the above-mentioned fast retracting action does not impair the shading function of the shading, the fast retracting causes the components to collide with each other. For example, when the side strip Γ4 = to the bottom dead center, the shell is often directly hit by the inertia. If you don't make an abnormal sound that will cause a component to collide, it will also cause vibration of the component. Therefore, this: =1 is less refined, and a high-class car will not buy such a sunshade! Therefore, its scope of application will be limited. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a way to alleviate

The sunshade unit 2 has other structures' but it is a general design, so here is not More details. The guiding unit 3 includes a rail seat 3 mounted under the housing 21 and extending vertically upward and downward, and a guide rod 32 extending downward from the side strip 24 and longitudinally sliding along the rail seat 31. . The holder 31 has a guide groove 3 ι which extends vertically upward and downward and which is fitted with the guide rod 32, and a slot 312 which is located below the guide rod 32 and extends vertically upward and downward. The buffer unit 4 includes a mounting bracket 41 fixed to the bottom side of the rail base 31, and is mounted on the mounting bracket and has a buffer resistance 201224267 buffer 42 which can be driven by the guide rod 32. The damper 43' of the damper and the elastic member 44 attached to the bottom of the rail seat 31 and abutting against the escaping seat 43. The damper 42 has a mounting plate 421 mounted to the yoke 2 toward the rail seat 31, and a damper gear 422 rotatably mounted on the mounting plate 421. The damper 42 has a brake function, but it is constructed as a common technique and is not the focus of the present invention, and a commercially available damper can also be used, and therefore will not be described in detail herein. The linkage 43 has a strip 43 extending longitudinally and longitudinally and engaging the damper gear 422 and a foot rod 432 engaging the rack 43 and extending into the holder 31 below the guide rod 32. The leg 432 is inserted into the slot 312 laterally by the bottom end of the rack 43!, and can be moved 2 times along the slot. The elastic member 44 is a __ now (four) spring, which is installed on the handle. The bottom of the 31 and the top of the foot bar 432 have a constant elastic force for pressing the connecting seat to the top. In use, the curtain 23 can be driven relative to the housing 21, as shown in FIG. The unfolded position outside the housing 21 is shown to be moved between the reeling position in which the reel is taken by the reel 22 as shown in Fig. 3 and moved to the inside of the housing η. The user 2 pulls the side strip 24 upwards and pulls the curtain 23 from the roll of FIG. 3 and stretches upward. At this time, the side strip 24 will drive the guide rod 32 to move upward, and the reel 22 The reeling force is also accumulated. (4) The side strip (4) is hung and positioned on an upper hanging seat (not shown), so that the cord 23 is moved to the unfolded position of FIG. 2, and the elastic member 44 also has the connecting seat 43. Push up and reset. Of course, the design can also make the curtain 23 pull out when it can be pulled up with the 6 201224267, so the pedestal can be omitted and the side strip 24 The hooking structure is not redundant here. When the curtain 23 is to be switched from the unfolded position of FIG. 2 to the retracting position of FIG. 3, the side strip 24 is first disengaged from the hanging seat, and the reel is received at this time. In the winding action of the 22, the side strip 24 also moves the guide rod to move downward rapidly, until the final stage of the folding, the guide rod 32 will step on the foot cup 432 and drive down, and the rack 431 It also moves and engages the rotating damper gear 422', and the rack 43 丨 is subjected to the temperature-blocking action of the damper gear ,, which will slow down the speed of the downward movement, causing the guide rod 32 to collapse. The speed at which the cord 23 is retracted is gradually slowed down until the full stop is stopped in the retracting position, so as to prevent the curtain 23 from striking the housing 21. Referring to Figure 4, a second preferred embodiment of the semi-automatic sunshade of the present invention Ratherly the same as the first embodiment, it also includes: a sunshade unit 2, a guide sheet A 3 ' and a buffer unit 4. The configuration of the buffer unit 4 of the present embodiment is slightly different, and the buffer 42 has a hollow cylinder 423 for accommodating fluid, one movably A piston 424' installed in the cylinder 423 and a piston rod 425 extending into the top side of the red cylinder 423 and engaging the piston 424. The rainbow 423 is filled with air to provide cushioning resistance. The cylinder 423 has at least one vent hole 426 located at the bottom and communicating with the outside. When the piston 424 moves downward to squeeze the fluid, the pressure can be slowly released. Of course, the cylinder 423 can also contain liquid. The arrangement of the venting opening 426 is omitted and will not be described here. The connecting seat 43 is a truss rod that engages the piston rod 425 and extends into the rail seat 31 and the 201224267 is located below the guiding rod 32. The elastic member 44 is mounted in the cylinder 423 and abuts against the piston 424, and has an elastic force for constantly pushing the piston 424 and the piston rod 425 upward. When the curtain 23 is switched from the deployed position of FIG. 4 to the final stage of the retracting position of FIG. 5, the piston rod 425 moves along with the piston 424 as the guide rod 3 2 moves downward. The squeezing fluid is moved downward, thereby generating a resistance to the linkage 43 and the guide rod 32, which can also gradually slow down the winding speed. Referring to Fig. 6', the configuration of the third preferred embodiment of the semi-automatic sunshade of the present invention is substantially the same as that of the second embodiment, except that the elastic member 44 of the buffer unit 4 of the present embodiment changes the mounting position by the second The buffer 42 of the embodiment is moved to the bottom of the rail seat 31, and the top end of the connecting bracket 43' has '(································ The arrangement of the unit 4 can also achieve the purpose of slowing down the winding speed. As can be seen from the above description, the semi-automatic sunshade of the present invention mounts the buffer unit 4 on the guiding unit 3 to provide the winding resistance, not only not seen in In the past, the sunshade 'this design allows the curtain 23 to be retracted in a gentle manner at the end of the winding, so as to avoid noise and vibration caused by the collision between the components when the curtain 23 is wound up, therefore, the present invention does The utility model has the advantages of reducing the noise and vibration of the winding, and can promote the exquisiteness of the product, so that the object of the invention can be achieved. The above is only the preferred embodiment of the invention, when not The scope of the present invention is defined by the scope of the present invention, and the simple equivalent changes and the repairs made by the invention in the scope of the invention and the invention are still within the scope of the present invention.
