An automobile sunroof windscreen support structure

Abstract

The present invention relates to a support structure for a windshield net of an automobile, belonging to the technical field of windshield nets. In the present invention, the windshield net is installed on a rectangular ring, and when folded, the rectangular ring can be directly laid down and inserted into the U-shaped seat. The windshield net is always in a flat state, so that when storing, it is not necessary to fold the windshield net irregularly, avoiding the problems of uneven stress and material fatigue caused by long-term and multiple irregular foldings of the windshield net, reducing the risk of wear and tear of the windshield net, and extending the service life of the windshield net. At the same time, the windshield net in the storage state is above the driver's seat and the passenger seat, which can shade the people in these two positions. And when the windward side of the windshield net catches leaves or other large particles, when it is unfolded for the second time, the side with the caught leaves is placed at the rear. Then, when the car is driving fast, the wind will blow through the windshield net to the leaves or objects, easily blowing the leaves or objects off the windshield net to achieve the cleaning of the windshield net.

Description

Technical Field

[0001] The present invention relates to the technical field of windshield nets, and particularly to a support structure for a windshield net of an automobile sunroof. Background Art

[0002] An automobile sunroof windshield net is a device installed above the automobile sunroof. Its main function is to block the wind from entering the vehicle, reduce wind noise and the impact of the wind, while maintaining the air circulation inside the vehicle. The automobile sunroof windshield net can also prevent sundries or insects from entering the vehicle, protecting the safety and comfort of the passengers inside the vehicle. The windshield net needs a support structure to be installed on the edge of the automobile sunroof, and at the same time, the support structure is used to control the opening and closing of the windshield net.

[0003] The patent with the publication number CN118322816A discloses a low-wind-noise self-locking windshield net. In this prior art, during the process of the torsion spring jacking up the guide plate, the second telescopic rod and the second spring will simultaneously push the second mounting bracket and the fixed block. By using the second telescopic rod and the second spring to assist in jacking up the fixed block and the connecting head, the upper frame assembly can be smoothly unfolded. When the vehicle jolts during driving, the second telescopic rod and the second spring strengthen the support for the upper frame assembly, reducing the displacement generated when the upper frame assembly is vibrated.

[0004] However, the above prior art has the following technical defects:

[0005] First, when the upper frame assembly is retracted into the lower frame assembly in this prior art, the windproof net will be folded, and this folding is irregular. The irregular folding may cause uneven local stress on the net surface, increasing the risk of wear and tear. Moreover, long-term folding will cause material fatigue, resulting in the windshield net breaking, tearing or aging, shortening the service life of the windshield net.

[0006] Second, during the driving of the vehicle, some fallen leaves or large particle objects may get stuck on the windward side of the windshield net. Since these objects are on the windward side of the windshield net, it is very difficult for them to fall off. At the same time, these objects will block some mesh holes, and cause the wind to form a turbulent flow at the blocked part, thereby increasing the noise during driving and increasing the driving resistance of the vehicle.

[0007] In summary, there is still room for improvement in the prior art in terms of improving the service life of the windshield net and cleaning the objects stuck on the windward side of the windshield net. Therefore, this application proposes a support structure that does not fold the windshield net and can clean the objects stuck on the windshield net. Summary of the Invention

[0008] In order to solve the above problems, this application provides a support structure for a windshield net of an automobile sunroof, adopting the following technical solutions:

[0009] It includes a U-shaped seat with its edges bent vertically upward.

[0010] It includes a mounting mechanism installed on the U-shaped seat. The mounting mechanism includes two symmetrically arranged rotating seats. There is a U-shaped frame with an upward opening hinged between the two rotating seats. A rectangular frame is rotatably installed between the inner sides of the U-shaped frame.

[0011] It also includes a deflection mechanism. The deflection mechanism includes two main racks symmetrically and slidably arranged on the upper side of the U-shaped seat. The upper side of the main rack is hinged with a deflection rod. The upper end of the deflection rod is hinged with the side of the U-shaped frame. On the upper side of the U-shaped seat, deflection gears meshing with the main racks are rotatably installed on one side of the main racks. A secondary rack adapted to the deflection gear is slidably arranged on one side of the deflection gear. A mounting seat is installed on the upper side of the secondary rack, and a push block is installed on the upper side of the mounting seat.

[0012] Preferably, a mounting plate is installed on the inner side of the U-shaped seat on one side of the mounting seat. A deflection spring is connected between the mounting plate and the mounting seat.

[0013] Preferably, a limit magnet is arranged at the end of the main rack on the upper side of the U-shaped seat, and an iron block adapted to the limit magnet is installed at the end of the main rack.

[0014] Preferably, a first gear is arranged at the end of the rotating shaft of the rectangular frame on the U-shaped frame. A one-way clutch is arranged between the first gear and the end of the rotating shaft.

[0015] Preferably, a threaded cylinder is rotatably installed on the side of the U-shaped frame on one side of the first gear. A screw rod adapted to the threaded cylinder is arranged inside the threaded cylinder.

[0016] Preferably, two rectangular grooves are symmetrically opened on the side of the rectangular frame with the rotating shaft as the center. A rectangular plug inserted into one of the rectangular grooves is installed at the end of the screw rod.

[0017] Preferably, a first magnet is slidably arranged on the other side of the first gear, and a reset spring is arranged on one side of the first magnet.

[0018] Preferably, a rotating rack meshing with a second gear is installed on the lower side of the first magnet, and the first gear is adapted to the rotating rack.

[0019] Preferably, an L-shaped iron sheet adapted to the first magnet is installed on the side of the mounting seat.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. In the present invention, the windscreen is installed on a rectangular ring. When folding, the rectangular ring can be directly laid down and inserted into the U-shaped seat. The windscreen always remains flat, so that when storing, there is no need to fold the windscreen irregularly, avoiding problems such as uneven stress and material fatigue caused by long-term and multiple irregular foldings of the windscreen, reducing the risk of wear and tear of the windscreen, prolonging the service life of the windscreen, and at the same time, the windscreen in the storage state is above the driver's seat and the passenger seat, which can shade the people in these two positions.

[0022] 2. After the windscreen is stored in the present invention, the windscreen can be rotated 180 degrees, so that both sides of the windscreen can face the wind alternately. By using both sides alternately, each side can be evenly stressed, reducing the risk of unilateral wear, thereby prolonging the service life of the entire windscreen. And when leaves or other large particles are stuck on the windward side of the windscreen, when it is unfolded for the second time, the side with the stuck leaves can be placed at the back. Then, when the vehicle is moving fast, the wind will blow through the windscreen onto the leaves or objects, and since there is no restriction of the windscreen, the leaves or objects can be easily blown off the windscreen, realizing the cleaning of the windscreen.

[0035] The following Figure 1 - Figure 10 will describe the embodiments of the present invention in detail.

[0036] The embodiment of the present application discloses a support structure for a windshield net of an automobile sunroof. The windshield net is installed on a rectangular ring. When folding, the rectangular ring can be directly laid down and put into the U-shaped seat. The windshield net is always in a flat state, so that when storing, it is not necessary to fold the windshield net irregularly, avoiding the problems of uneven stress and material fatigue caused by long-term and multiple irregular foldings of the windshield net, reducing the risk of wear and tear of the windshield net, and prolonging the service life of the windshield net. Embodiment 1:

[0037] As Figure 1 - Figure 2 shown, it includes a U-shaped seat 1 with its edges bent vertically upward. The U-shaped seat 1 is the main body of the device and is used to install other structures in the device.

[0038] As Figure 1 , Figure 3 and Figure 4 shown, it includes an installation mechanism 2 installed on the U-shaped seat 1. The installation mechanism 2 includes two symmetrically arranged rotating seats 201. A U-shaped frame 202 with an upward opening is hinged between the two rotating seats 201. A rectangular frame 203 is rotatably installed between the inner sides of the U-shaped frame 202. A windshield net adapted to its size is installed inside the rectangular frame 203. And the rectangular frame 203 is rotatably connected to the U-shaped frame 202. The rotating rectangular frame 203 can drive the windshield net to rotate, so that both sides of the windshield net can face the wind;

[0039] As Figure 5As shown in the figure, a first gear 204 is provided at the rotating shaft end of the U-shaped frame 202 of the rectangular frame 203. A one-way clutch 205 is provided between the first gear 204 and the rotating shaft end. When the first gear 204 rotates, the rectangular frame 203 can be driven to rotate through the one-way clutch 205. When the first gear 204 rotates in reverse, the rectangular frame 203 will not be driven to rotate in reverse due to the one-way clutch 205.

[0040] As Figure 5 shown, magnetic pieces 217 are embedded on one side of each rectangular slot 208 on the side surface of the rectangular frame 203. Fixed pieces made of iron and aligned with the magnetic pieces 217 are embedded on one side of each magnetic piece 217 on the inner side surface of the U-shaped frame 202. The fixed pieces are magnetically attracted to the magnetic pieces 217 to enhance the stability between the U-shaped frame 202 and the rectangular frame 203.

[0041] As Figure 4 and Figure 5 shown, a threaded cylinder 206 is rotatably installed on one side of the first gear 204 on the side surface of the U-shaped frame 202. A screw rod 207 adapted to the threaded cylinder 206 is arranged inside the threaded cylinder 206. Two rectangular slots 208 are symmetrically opened on the side surface of the rectangular frame 203 with the rotating shaft as the center. A rectangular plug 209 extending into one of the rectangular slots 208 is installed at the end of the screw rod 207. Due to the U-shaped frame 202 limiting the rotation of the rectangular plug 209 to prevent its self-rotation, when the threaded cylinder 206 rotates, the screw rod 207 is driven away from the rectangular frame 203, driving the rectangular plug 209 out of the rectangular slot 208 to release the fixation of the rectangular frame 203.

[0042] As Figure 4 shown, a group of rectangular blocks 211 are installed on the other side of the first gear 204. A rectangular rod 212 is installed between the two rectangular blocks 211. A first magnet 213 is slidably arranged on the rectangular rod 212. A return spring 214 is arranged between the first magnet 213 and one of the rectangular blocks 211. The first magnet 213 can slide on the rectangular rod 212. When the rectangular rod 212 approaches the return spring 214, the return spring 214 will be compressed. At the same time, when the return spring 214 rebounds, it will drive the first magnet 213 to restore its position.

[0043] As Figure 4 shown, a rotating rack 215 meshing with the second gear 210 is installed on the lower side of the first magnet 213. The first gear 204 is adapted to the rotating rack 215. A limiting block 216 is installed on the side surface of the U-shaped frame 202 below the rectangular rod 212. When the first magnet 213 moves, it will drive the rotating rack 215 to move. The moving rotating rack 215 will drive the second gear 210 to rotate. When it meshes with the first gear 204, it will also drive the first gear 204 to rotate. When the limiting block 216 contacts the rotating rack 215, it will limit the rotating rack 215.

[0044] In summary, when the windshield is installed inside the rectangular frame 203, when the first magnet 213 moves towards the limiting block 216, it drives the rotating rack 215 to move in the same direction and also compresses the return spring 214. The moving rotating rack 215 drives the threaded barrel 206 to rotate through the second gear 210. The rotating threaded barrel 206 drives the screw rod 207 to move in the opposite direction of the rectangular slot 208, driving the rectangular pin 209 to move. When the rectangular pin 209 completely moves out of the rectangular slot 208, the rotating rack 215 just meshes with the first gear 204. Then, the moving rotating rack 215 drives the first gear 204 to rotate, causing the rectangular frame 203 and the windshield to rotate, and at the same time disconnecting the magnetic sheet 217 from the fixed sheet. When the rotating rack 215 contacts the limiting block 216, the rectangular frame 203 just rotates 180 degrees. At this time, the magnetic sheet 217 is magnetically attracted to the aligned fixed sheet again. Then, the return spring 214 rebounds and drives the rotating rack 215 to move quickly in the reverse direction, thereby driving the second gear 210 and the threaded barrel 206 to reverse, causing the screw rod 207 to move in the reverse direction so that the rectangular pin 209 quickly re-inserts into the aligned rectangular slot 208. And because of the one-way clutch 205, the reversed first gear 204 will not drive the rectangular frame 203 to rotate.

[0045] As Figure 6 and Figure 7 shown, it further includes a deflection mechanism 3. The deflection mechanism 3 includes two main racks 301 symmetrically and slidably arranged on the upper side of the U-shaped seat 1. The upper side of the main rack 301 is hinged with a deflection rod 308. The upper end of the deflection rod 308 is hinged with the side surface of the U-shaped frame 202. When the main rack 301 moves in the opposite direction of the U-shaped frame 202, it drags the U-shaped frame 202 to rotate around the hinge with the rotating seat 201 through the deflection rod 308 until the U-shaped frame 202 lies down. And when the main rack 301 moves towards the U-shaped frame 202, it makes the U-shaped frame 202 rotate 90 degrees in the reverse direction around the hinge through the deflection rod 308 to make it unfold.

[0046] As Figure 6 and Figure 7 shown, deflection gears 302 meshing with them are rotatably installed on the upper side of the U-shaped seat 1 on one side of the main rack 301. A secondary rack 303 adapted to it is slidably arranged on one side of the deflection gear 302. When the secondary rack 303 moves towards the U-shaped frame 202, it drives the main rack 301 to move away from the U-shaped frame 202 through the deflection gear 302, and vice versa.

[0047] As Figure 6 and Figure 7As shown, a mounting seat 304 is installed on the upper side of the secondary rack 303, and a push block 306 is installed on the upper side of the mounting seat 304. On the inner side of the U-shaped seat 1, a mounting plate 309 is installed on one side of the mounting seat 304. A deflection spring 305 is connected between the mounting plate 309 and the mounting seat 304. When the skylight glass is closed, after the moving glass contacts the push block 306, it pushes the push block 306 forward. At the same time, when the deflection spring 305 is stretched by the mounting seat 304, the secondary rack 303 will also be driven to move. When the skylight glass is opened, without the support of the skylight glass, the stretched deflection spring 305 drives the mounting seat 304 and the secondary rack 303 to move in the reverse direction.

[0048] As Figure 6 and Figure 7 shown, on the inner side of the U-shaped seat 1, a special-shaped groove 307 adapted to the side of the combination of the secondary rack 303, the mounting seat 304 and the push block 306 is provided on one side of the mounting seat 304. A square rod 310 passing through the mounting seat 304 and fixedly connected to the inner wall of the special-shaped groove 307 is installed on the side of the mounting plate 309. The mounting seat 304 slides on the square rod 310, enhancing the stability of the mounting seat 304 during movement. At the same time, when the sides of the secondary rack 303, the mounting seat 304 and the push block 306 completely enter the special-shaped groove 307, the skylight glass just fits against the inner wall of the U-shaped seat 1, realizing the closing of the skylight.

[0049] As Figure 6 and Figure 7 shown, a limit magnet 311 is provided on the upper side of the U-shaped seat 1 at the end of the main rack 301. An iron block 312 adapted to the limit magnet 311 is installed at the end of the main rack 301. The moving main rack 301 drives the iron block 312 to move until the iron block 312 contacts the limit magnet 311, and then the iron block 312 is magnetically attracted to the limit magnet 311, strengthening the stability of the main rack 301.

[0050] As Figure 6 and Figure 7 shown, an L-shaped iron sheet 6 adapted to the first magnet 213 is installed on the side of the mounting seat 304. The moving mounting seat 304 also drives the iron sheet 6 to move. When the moving iron sheet 6 contacts the first magnet 213, it will be magnetically connected to the first magnet 213, and the iron sheet 6 drives the first magnet 213 to move.

[0051] In summary, when the skylight glass is closed, the moving glass contacts the push block 306 and then pushes it forward. At the same time, the deflection spring 305 is stretched by the mounting seat 304, and the secondary rack 303 is also driven to move towards the U-shaped frame 202. The main rack 301 is driven away from the U-shaped frame 202 by the deflection gear 302, and the U-shaped frame 202 is pulled by the deflection rod 308 to rotate around the hinge with the rotating seat 201 until the rectangular frame 203 lies down. After that, the skylight glass continues to push the push block 306 to move until the secondary rack 303, the mounting seat 304, and the side of the push block 306 completely enter the special-shaped groove 307, and the skylight glass just fits against the inner wall of the U-shaped seat 1, realizing the closing of the skylight.

[0052] When the skylight glass is opened, without the support of the skylight glass, the stretched deflection spring 305 drives the mounting seat 304 and the secondary rack 303 to move in the reverse direction. The moving mounting seat 304 also drives the iron sheet 6 to move. When the iron sheet 6 is magnetically attracted to the first magnet 213, it drives the first magnet 213 to move in the same direction. Until the secondary rack 303 meshes with the deflection gear 302, the reversely moving secondary rack 303 drives the main rack 301 to move towards the U-shaped frame 202 through the deflection gear 302, and the U-shaped frame 202 is rotated reversely by ninety degrees around the hinge through the deflection rod 308, causing the rectangular frame 203 to unfold. Embodiment 2:

[0053] Based on Embodiment 1, as Figure 8 - Figure 10 shown, a fixing mechanism 4 is further provided. The fixing mechanism 4 includes a fixing seat 401 installed on the upper side of the main rack 301. A movable plate 402 adapted to it is slidably arranged in the cavity of the fixing seat 401. A second spring 406 is arranged on one side of the movable plate 402. When the movable plate 402 moves towards the second spring 406, it will compress the second spring 406. After that, when the second spring 406 rebounds, it will drive the position of the movable plate 402 to be restored.

[0054] As Figure 8 - Figure 10 shown, a fixing plate 404 is installed on the upper side of the U-shaped seat 1 on one side of the fixing seat 401. An empty groove 405 is formed on the side surface of the fixing plate 404. A plug 403 extending into the empty groove 405 is installed at the center of the side surface of the movable plate 402. When the plug 403 is inserted into the empty groove 405 of the fixing plate 404, the main rack 301 and the U-shaped seat 1 are fixed to enhance their stability.

[0055] As Figure 8 - Figure 10 shown, inclined surfaces are arranged on both sides of the plug 403. An extrusion seat 5 adapted to the plug 403 is installed on the upper side of the secondary rack 303. When the fixing seat 401 moves towards the fixing plate 404, the inclined surface on the front side of the plug 403 will squeeze the fixing plate 404 to make the plug 403 move into the fixing seat 401. When the extrusion seat 5 moves towards the plug 403, it will squeeze the inclined surface on the rear side of the plug 403 to make it move into the fixing seat 401.

[0056] In summary, when the main rack 301 moves towards the U-shaped frame 202 to rotate and unfold the U-shaped frame 202, the moving main rack 301 drives the fixed seat 401 to move. The inclined surface on the front side of the plug-in 403 will squeeze the fixed plate 404 to make the plug-in 403 move into the fixed seat 401, and at the same time compress the second spring 406 until the plug-in 403 aligns with the empty slot 405. The compressed second spring 406 rebounds to drive the plug-in 403 to snap into the empty slot 405 to limit and fix the main rack 301. When the sunroof is closed, the moving secondary rack 303 will drive the extrusion seat 5 to move. The moving extrusion seat 5 squeezes the inclined surface on the rear side of the plug-in 403 and presses it into the empty slot 405. At the same time, the side surface of the extrusion seat 5 is used to limit the plug-in 403. At this time, the secondary rack 303 meshes with the deflection gear 302, and then drives the main rack 301 to move in the opposite direction of the U-shaped frame 202, so that the inner side surface of the empty slot 405 squeezes the inclined surface on the rear side of the plug-in 403 and continues to press it into the fixed seat 401. When the plug-in 403 is separated from the fixed plate 404, the second spring 406 rebounds to drive the plug-in 403 to restore its position.

[0057] The working principle of the present invention:

[0058] S1. Structure installation: Install the device at the edge of the car sunroof close to the front of the vehicle. Specifically, install the windshield net adapted to the inner frame size of the rectangular frame 203 in the frame of the rectangular frame 203, and then install the device at the edge of the car sunroof close to the front of the vehicle. When the vehicle is moving forward, the windshield net can effectively reduce the direct entry of wind, thereby reducing the noise inside the vehicle, improving the riding comfort, and at the same time keeping the air inside the vehicle circulating and making the air inside the vehicle fresher.

[0059] S2. Net surface closing: When the sunroof is closed, let the rectangular frame 203 lie down to store the windshield net. Specifically, when the sunroof glass is closed, after the moving glass contacts the push block 306 and pushes it forward, at the same time, while stretching the deflection spring 305 through the mounting seat 304, it will also drive the secondary rack 303 to move towards the U-shaped frame 202. The deflection gear 302 drives the main rack 301 away from the U-shaped frame 202, and the deflection rod 308 drags the U-shaped frame 202 to rotate around the hinge with the rotating seat 201 until the U-shaped frame 202 drives the rectangular frame 203 to lie down. Then the sunroof glass continues to push the push block 306 to move until the secondary rack 303, the mounting seat 304, and the side surface of the push block 306 completely enter the special-shaped groove 307, and the sunroof glass just fits against the inner wall of the U-shaped seat 1 to achieve sunroof closing.

[0060] S3. The mesh rotates. When the sunroof is unfolded, the rectangular frame 203 rotates 180 degrees around the connection where it rotates with the U-shaped frame 202. Specifically, when the sunroof glass is opened, without the support of the sunroof glass, the stretched deflection spring 305 drives the mounting seat 304 and the secondary rack 303 to move in the opposite direction. The moving mounting seat 304 also drives the iron sheet 6 to move. When the iron sheet 6 is magnetically attracted to the first magnet 213, it drives the first magnet 213 to move in the same direction, drives the rotating rack 215 to move in the same direction, and at the same time compresses the return spring 214. The moving rotating rack 215 drives the threaded barrel 206 to rotate through the second gear 210. The rotating threaded barrel 206 drives the screw 207 to move in the opposite direction of the rectangular groove 208, driving the rectangular pin 209 to move. When the rectangular pin 209 completely moves out of the rectangular groove 208, the rotating rack 215 just meshes with the first gear 204. Then, the moving rotating rack 215 drives the first gear 204 to rotate, causing the rectangular frame 203 and the windshield mesh to rotate.

[0061] S4. The mesh is fixed. When the rectangular frame 203 drives the windshield mesh to complete rotation, the rectangular frame 203 is fixed. Specifically, when the rectangular frame 203 rotates, the magnetic sheet 217 is disconnected from the fixed sheet at the same time. When the rotating rack 215 contacts the limit block 216, the rectangular frame 203 just rotates 180 degrees. At this time, the magnetic sheet 217 is magnetically attracted to the aligned fixed sheet again, and the continuously moving mounting seat 304 drives the iron sheet 6 to separate from the first magnet 213, allowing the return spring 214 to rebound and drive the rotating rack 215 to move quickly in the opposite direction, thereby driving the second gear 210 and the threaded barrel 206 to reverse, causing the screw 207 to move in the opposite direction so that the rectangular pin 209 quickly re-inserts into the aligned rectangular groove 208, strengthening the fixation between the U-shaped frame 202 and the rectangular frame 203. And because of the one-way clutch 205, the reversed first gear 204 does not drive the rectangular frame 203 to rotate.

[0062] S5. The mesh is unfolded. The continuously shrinking secondary rack 303 drives the U-shaped frame 202 to rotate around the rotation connection to unfold the rectangular frame 203. Specifically, the continuously shrinking mounting plate 309 until the secondary rack 303 meshes with the deflection gear 302, the reversely moving secondary rack 303 drives the main rack 301 to move towards the U-shaped frame 202 through the deflection gear 302, and through the deflection rod 308, the U-shaped frame 202 rotates reversely 90 degrees around the hinge, unfolding the rectangular frame 203.

[0063] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
