Obviously, the following description of the structure of the drawings is only some embodiments of the utility model.

[0030] Example

[0031] In view of all the currently disclosed technologies, the design schemes of the linked door rain shielding device are only applicable to ordinary door opening structures / methods, and cannot be applied to side-opening sliding door mechanisms. Therefore, we propose a linked door opening rain shielding device that can be applied to side-opening sliding doors. The specific scheme is as follows:

[0032] like Figure 1 As shown, the present embodiment provides a side-opening sliding door linkage rain shield device, comprising an outer protective shell 1, a linkage mechanism 2 and an umbrella cloth 3, wherein the linkage mechanism 2 is installed inside the outer protective shell 1, and the umbrella cloth 3 is installed on the linkage mechanism 2, the outer protective shell 1 is installed on the vehicle body at the top of the side sliding door of the vehicle, and the linkage mechanism 2 is connected to the top of the front edge of the side sliding door of the vehicle, so that the opening and closing of the side sliding door of the vehicle can synchronously drive the linkage mechanism 2 to move, thereby completing the opening and closing of the umbrella cloth 3.

[0033] The specific design is as follows:

[0034] Among them, Figure 1-2 As shown, the outer protective shell 1 includes a shell 101 and a base 104 .

[0035] And as Figure 2-3 As shown, the linkage mechanism 2 includes a slide rail 201, which is installed on the base 104 and parallel to the base 104. A base 202 is also slidably installed on the slide rail 201. Elastic support components 204 are installed at both ends of the base 202, and a reel 205 is installed on the base 202 through two groups of elastic support components 204. An umbrella rib 207 is rotatably installed on the base 202 near the front end of the reel 205 through a No. 1 hinge seat 206.

[0036] The linkage mechanism 2 also includes a support rod 209 rotatably mounted at the middle of the base 104 through a second hinge seat 208, a pin 210 is installed on one side of the middle of the umbrella rib 207, and the front end of the support rod 209 is rotatably connected to the umbrella rib 207 through the pin 210. Further, a mounting block 212 is fixed to the front end of the base 202, a linkage rod 213 parallel to the slide rail 201 is installed at the bottom of the mounting block 212, and a linkage plate 214 for fixing to the top of the front edge of the vehicle side sliding door is installed at the end of the linkage rod 213. One side of the umbrella cloth 3 is fixed on the reel 205, and the other side of the umbrella cloth 3 is fixed on the umbrella rib 207. The umbrella cloth 3 adopts a four-point The ribs 207 are designed in a circle, the length of the reel 205 is adapted to the width of the side sliding door of the vehicle, the radius length of the umbrella cloth 3 is consistent with the length of the ribs 207, the side sliding door slides back and forth, and the linkage plate 214 drives the linkage rod 213 to move, and finally drives the base 202 to move back and forth on the slide rail 201. With the help of the fixed-position design of the support rod 209, one end of the ribs 207 can be driven to move during the movement of the base 202, so that the position where the support rod 209 and the ribs 207 rotate and cooperate forms a fulcrum, so that the ribs 207 can be opened or closed, and when the ribs 207 are opened, the umbrella cloth 3 is pulled to make the umbrella cloth 3 unfold to form an umbrella cover that blocks rain.

[0037] In order to prevent the shell 101 of the outer protective shell 1 from hindering the ribs 207 in the linkage mechanism 2 from unfolding, Figure 1As shown, an opening 102 is provided on the side of the shell 101 of the outer protective shell 1, so that the linkage mechanism 2 can extend from the inside of the shell 101 to unfold the umbrella cloth 3. In order to avoid generating a large wind noise at the position of the opening 102 when the vehicle is driving, a soft brush (not shown) is also installed on the inner side of the opening 102. Under the premise of not affecting the opening of the umbrella ribs 207, the opening 102 can also have an effective wind-blocking effect after the umbrella ribs 207 are completely retracted into the inner part of the outer protective shell 1, thereby reducing the wind noise.

[0038] Since the linkage mechanism 2 needs to be designed to be linked with the side sliding door of the vehicle, in order to prevent the shell 101 from hindering the movement of the linkage plate 214, a long avoidance slot 103 is provided at the bottom of the shell 101 for linkage installation between the linkage mechanism 2 and the vehicle door.

[0039] like Figure 1 As shown, in order to reduce the wind resistance of the device as much as possible, the front end of the housing 101 is designed with a slope.

[0040] In order to facilitate the installation and subsequent maintenance of the device, the housing 101 and the base 104 are fixed by screws. The base 104 is installed on the side of the top frame of the vehicle side sliding door, and the base 104 is parallel to the sliding direction of the vehicle side sliding door.

[0041] like Figure 3 As shown, in order to facilitate the side sliding door of the vehicle to cooperate with the linkage rod 213 to effectively drive the umbrella rib 207 to perform the unfolding operation, a limiting block 203 is installed at the rear end of its slide rail 201 by bolts. When the rear end of the base 202 touches the limiting block 203, the umbrella rib 207 and the base 202 form an angle of 90 degrees, and the umbrella rib 207 is now located at the upper front side of the side sliding door of the vehicle.

[0042] like Figure 4 As shown, a long slot 211 is provided at the front end of the support rod 209, and a pin shaft 210 at the middle of the rib 207 is designed in a "┐" shape, and the pin shaft 210 is movably connected in the slot 211. In this design, the slot 211 is provided to allow the connection between the support rod 209 and the rib 207 to have a certain movable buffer space to prevent movement interference between the support rod 209 and the rib 207, and the "┐"-shaped pin shaft 210 is designed to ensure that a certain inclination angle is formed between the support rod 209 and the rib 207 after the rib 207 is fully folded, which is conducive to the rib 207 being reopened under the action of the support rod 209 when the base 202 moves.

[0043] Since the umbrella cloth 3 is designed in a fan shape, in order to make the rolling of the umbrella cloth 3 more convenient, the diameter of the reel 205 is designed to increase from the front end to the rear end, which helps the umbrella cloth 3 to be unfolded and retracted at a uniform speed.

[0044] As is known to all, there is an essential difference between the opening of a side sliding door and an ordinary door opening method. Generally, a side sliding door will be fully opened under habitual driving, that is, the side sliding door needs to be fully opened to the rear of the vehicle. In order to minimize the moving distance of the ribs 207, the length of the ribs 207 is controlled within a reasonable range while ensuring that the door is fully opened when the ribs 207 are fully opened to prevent the linkage mechanism 2 from causing motion interference with the movement of the door. The linkage rod 213 is designed as a telescopic rod, and the linkage rod 213 is arranged toward the rear end of the base 202, so as to form a certain linkage buffering effect between the linkage mechanism 2 and the door during the side sliding movement, so that the door can effectively drive the linkage mechanism 2 to move when it is about to be fully opened or about to be fully closed.

[0045] During the opening and closing process of the side sliding door of the vehicle, the door needs to move outward or inward a certain distance, that is, the front top of the door is not a straight line during the sliding process. In order to enable the linkage mechanism 2 to adapt to this phenomenon and thus fully adapt to the opening and closing operations of the side sliding door, a rotatable installation design is adopted between the linkage plate 214 and the end of the linkage rod 213, and the linkage plate 214 and the linkage rod 213 are designed to be vertical.

[0046] In order to facilitate the umbrella cloth 3 to automatically complete the rolling work in cooperation with the umbrella ribs 207 when the car door is closed, Figure 4 As shown, the elastic support assembly 204 includes a bearing seat 241 fixed on the base 202, and the opposite side of the bearing seat 241 in the two sets of elastic support assemblies 204 is equipped with a speed change assembly 242, and the opposite side of the bearing seat 241 in the two sets of elastic support assemblies 204 is fixed with a protective cover 244, and the two protective covers 244 are installed with a spring 243. Due to the limitation of the installation space, the number of rotations of the spring 243 is limited, and if the umbrella cloth 3 needs to be fully unfolded, the number of rotations of the winding shaft 205 is much greater than the number of rotations of the spring 243. In order to make the spring 243 work normally, the speed change assembly 242 adopts a two-stage gear speed change mechanism composed of large and small gears meshing with each other. : The two-stage gear speed change mechanism assembled by meshing large and small gears is the most common type of transmission method in the current transmission design, so it is not described in detail in the article; the large gear shaft in the speed change component 242 is the input end, and the small gear shaft in the speed change component 242 is the output end, and the two ends of the winding shaft 205 are fixedly connected to the small gear shaft in the corresponding end of the speed change component 242, and the large gear shafts in the two groups of speed change components 242 pass through the bearing seat 241 and are fixed to one end of the spring 243, and the other end of the spring 243 is fixed to the protective cover 244. In this design, it should be noted that the installation direction of the springs 243 in the two groups of elastic support components 204 needs to be sequentially tightened or reset at the same time when the winding shaft 205 rotates.

[0047] When the side sliding door of the vehicle is closed, the linkage rod 213 is first retracted, and the linkage rod 213 loses the effective pulling traction force on the base 202, resulting in the base 202 losing the external force positioning. Since the umbrella cloth 3 is forcibly pulled by the umbrella cloth 3 during the unfolding process of the umbrella ribs 207, the reel 205 is forced to rotate, causing the spring 243 to rotate vigorously. When the umbrella ribs 207 lose the support of the traction force, the spring 243 exerts force to cause the reel 205 to reset and rewind the umbrella cloth 3. In this process, the umbrella ribs 207 are gradually retracted under the action of the spring 243 and the linkage rod 213 until the base 202 moves to the front end of the base 104 under the action of the retracted linkage rod 213 and returns to the initial position.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
