The effect of the invention is that the design of the positioning unit enables the sunshade unit to be manually moved to the deployed position, i.e., the automatic snap positioning, which is quite convenient to use. [Embodiment] The foregoing and other technical features, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to FIG. 2 and FIG. 3, a first preferred embodiment of the semi-automatic sunshade according to the present invention is installed in a door (not shown) of a car, and is used for correspondingly covering one side window (not shown) And the semi-automatic sunshade comprises: a sunshade unit 2, a guiding unit 3, and a positioning unit bucket. The sunshade unit 2 includes a housing 21 that is hollow and has an opening (not shown) on the top side, a reel 22 that is rotatably mounted about the axis of the housing 21 and has an elastic force. A piece of cord 23 that can be wound around the outer periphery of the reel 22, and a side of the reel 22 that is mounted away from one end edge of the reel 22 and located outside the housing 21: 201224269 side: However, the sunshade unit 2 further includes at least one elastic mechanism (the outer end of the elastic mechanism is fixed and the other end is connected to the reel 22' so that it can be twisted as the reel 22 rotates, and can be used to provide the reel 22 The elastic force of the scrolling direction of the constant direction is that the curtain 23 is automatically taken up by the reel 22 into the housing 21 when it is not subjected to an external force. Of course, the shading unit 2 has other configurations, but it is The general design is not described in detail here. The guiding unit 3 includes a guide rod 32 extending downward from the bottom side of the housing 2, and a guide rod 32 extending downward from the sill strip 24, and One is mounted on the bottom of the guide bar 32 and is slidable along the length of the seat 31 Block 33 〇 the rail seat 31 has a guide groove 311 ′ extending vertically upward and downward for the slide/ample 33 in the inner/month shift, and two slots located near the top and respectively from the guide groove 3 11 to the left and right sides The horizontally extending slot 3 12 . The guiding rod 32 and the sliding rod 33 can be made in the same body, or can be screwed together or otherwise combined, and will not be described here. The positioning unit 4 includes two left and right intervals. a latching mechanism 41 mounted on the slider 33, and an elastic mechanism 42 mounted between the latching mechanisms 41. Each latching mechanism 41 has a swingable mounting on the slider 33 a swing arm 411' and a roller 412 rotatably mounted on the swing arm 411 and rollingly contacting the side of the rail mount 31. The swing arm 411 has a pivot on the upper side and pivotally connected to the slider 33. a connecting portion 413, a resilient portion 414 opposite to the pivoting portion 41 3 and abutted by the elastic mechanism 42 , and a latch portion between the pivoting portion 413 and the resilient portion 414 for mounting the roller 412 415. In use, as long as the latch mechanism 41 can achieve the role of the 201224269 shackle on the rail seat 31, In practice, the number of the latching mechanisms 41 can also be changed, for example, only one is provided, and thus is not limited to the embodiment. The elastic mechanism 42 of the present embodiment has a compression spring mounted between the biasing portions 414. The elastic force of the swing arm 411 is reversely turned outwards with the pivoting portion 413 as the center, and the latching portion 415 can move the roller 412 to move toward the slot 312.
