Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

For convenience of description, in the following embodiments, the same components are denoted by the same reference numerals.

Referring to FIG. 2 and FIG. 3 , the first preferred embodiment of the semi-automatic sunshade of the present invention includes: a sunshade unit 2 , a guide unit 3 , and a buffer unit 4 . The whole set of the present invention is installed in a car door (not shown) of a car, and is used for correspondingly covering a side window (not shown).

The sunshade unit 2 includes a hollow shell base 21 with an opening 211 on the top side, a reel 22 installed in the shell base 21 that is rotatable around its own axis and has retractable elastic force, and a piece that can go toward the opening 211. The curtain 23 is rolled up on the periphery of the reel 22 , and an edge strip 24 is mounted on an edge of the curtain 23 away from the reel 22 and outside the opening 211 . Of course, the sunshade unit 2 also includes at least one elastic member (not shown), one end of the elastic member is fixed and the other end is connected to the spool 22, so it can be twisted as the spool 22 rotates, and can be used to provide the spool 22 The elastic force of constant rolling towards the rolling direction, that is to say, when no external force acts, the curtain 23 will be automatically rolled into the shell seat 21 by the scroll 22 . Of course, the sunshade unit 2 has other structures, but it is a general design, so it will not be described in detail here.

The guide unit 3 includes a rail seat 31 installed under the shell seat 21 and extending longitudinally up and down, and a guide rod 32 extending downward from the side bar 24 and slidable along the longitudinal direction of the rail seat 31 . The rail seat 31 has a guide groove 311 extending vertically and vertically for the guide rod 32 to slide. The guide rod 32 has a rod body 321 connected to the edge bar 24 , and a slider 322 mounted on the bottom of the rod body 321 and embedded in the guide groove 311 . The rod body 321 and the sliding block 322 can be made in one body, or can be screwed together or combined in other ways. Of course, the guide unit 3 can also increase the number of rail seats 31 and guide rods 32 in implementation. It is not limited to this embodiment.

The buffer unit 4 includes a first buffer member 41 rotatably mounted on the slider 322 , and a second buffer member 42 mounted on the bottom of the rail base 31 and corresponding to the first buffer member 41 . In this embodiment, the first buffer member 41 is a gear, and in practice, it can also be directly mounted on the bottom of the rod body 321 , and the setting of the slider 322 is omitted. The second buffer type 42 of this embodiment is a rack extending up and down in the long direction and engaged with the first buffer member 41. When in contact with the first buffer member 41, it produces a blocking effect and can be used to block the first buffer member 41. A buffer member 41 rolls. Of course, in terms of design, the first buffer member 41 can also be a damping wheel or a general roller instead of a gear, and the second buffer member 42 can also be a long strip with a rough surface, and the second buffer member 42 can also provide the first A buffer 41 provides braking force. In terms of material, the second buffer member 42 of this embodiment is made of soft materials such as silica gel or rubber, and the first buffer member 41 is made of a material that is relatively harder than the second buffer member 42, such as plastic. Of course, in practice, the first buffer member 41 can also be made of softer silicone or rubber material, and the second buffer member 42 is made of harder plastic material. On the whole, the first buffer member 41 And the second buffer member 42 is respectively made of a soft material and a hard material that interferes with each other, which can reduce abnormal noise, prolong the service life, and provide better buffering and deceleration effects, so the implementation is not based on this embodiment. limit.

When in use, the curtain 23 can be driven relative to the housing base 21 between an unfolded position stretched out of the housing base 21 and a retracted position driven by the reel 22 into the housing base 21 move. When wanting to unfold the curtain 23 for shading, the user holds the side bar 24 and pulls it upwards, and stretches the curtain 23 upwards from the retracted position. At this time, the side bar 24 will drive the guide rod 32 to move upwards, and at the same time The reel 22 also accumulates retracting elastic force until the side strip 24 is hooked and positioned on an upper hanger (not shown), so that the curtain 23 moves to the unfolded position. Of course, in terms of design, it is also possible to make the curtain 23 stop when it is pulled upwards, so that the hanging seat and the hooking structure between the hanging seat and the edge strip 24 can be omitted, and will not be described in detail here.

And when the curtain 23 wants to switch from the unfolded position to the retracted position, first let the side strip 24 disengage from the hanging seat, and at this time, the side strip 24 is also moved in conjunction with the retracting action of the reel 22 The guide rod 32 quickly moves downwards until it reaches the final stage of folding, the first cushioning member 41 will roll in contact with the second buffering member 42, and under the resistance of the second buffering member 42, the first buffering member 41 will The speed of the buffer member 41 will be relatively slowed down, causing the guide rod 32 to slowly descend, so the speed at which the curtain 23 is retracted can be gradually slowed down until it stops at the retracted position completely, so as to avoid the edge strip 24 from hitting the Shell seat 21.

Referring to Fig. 4, the second preferred embodiment of the semi-automatic sunshade of the present invention is roughly the same as the first embodiment, and also includes: a sunshade unit 2, a guide unit 3, and a buffer unit 4, and the buffer unit 4 is the same It includes a first buffer member 41 driven by the guide rod 32 to move along a moving route 411 , and a second buffer member 42 used to brake the rolling of the first buffer member 41 . Only the second buffer member 42 in this embodiment has an upper end 421 and a lower end 422 opposite up and down, and a blocking surface 423 connecting the upper end 421 and the lower end 422 and facing the moving route 411 of the first buffer member 41 . The blocking surface 423 gradually inclines from the upper end 421 to the lower end 422 to approach the moving route 411 .

When the curtain 23 is converted from the unfolded position to the final stage of the retracted position, the guide rod 32 drives the first buffer member 41 to move from the upper end 421 to the lower end 422 along the moving route 411, and at the same time the first The buffer member 41 will be engaged with the retarding surface 423. Since the retarding surface 423 is an inclined surface protruding downward gradually, the pushing force received by the first buffer member 41 will gradually decrease when the first buffer member 41 moves downward. increase, so the closer to the end of the retraction, the greater the resistance. Therefore, this embodiment can not only gradually slow down the speed at which the cord 23 is retracted, but also the retraction operation will become tighter and tighter until it stops, thus easing the positioning effect better.

Referring to Fig. 5, the third preferred embodiment of the semi-automatic sunshade of the present invention is substantially the same as the first embodiment or the second embodiment, the difference is: the first buffer member 41 and the second buffer of the buffer unit 4 The structure of the member 42 is exchanged, that is to say, the first buffer member 41 is a rack extending up and down, and the second buffer member 42 is a gear that is rotatable and engages with the first buffer member 41. It can also be To achieve the effect of easing curling.

From the above description, it can be seen that the semi-automatic sunshade of the present invention installs the buffer unit 4 on the guide unit 3 to provide rolling resistance, which is not seen in the past sunshade, and this design can make the curtain 23 roll up When the winding is about to end, the winding is carried out in a gentle manner to avoid noise and vibration caused by the collision between the elements when the curtain 23 is winding. Therefore, the present invention does have the effect of reducing the noise and vibration of winding, and can improve the exquisiteness of the product property, so the purpose of the present invention can really be achieved.
