Description

Technical Field

[0001] This invention belongs to the field of autonomous driving technology, specifically relating to an electric sunshade that is compatible with autonomous driving technology. Background Technology

[0002] Chinese patent document CN103568799A discloses an electric sunshade installed on a motor vehicle. This electric sunshade includes a seat with an internal cavity, a telescopic device on the seat, and a fabric support for movably winding a sunshade cloth. The telescopic device is fixed to the seat, and a motor is connected to and controls the telescopic device's telescopic movement. A support rod is located at the end of the telescopic device, connecting to the sunshade cloth on the fabric support. Under the control of the telescopic device, the sunshade cloth is stretched outwards for sun shading. Its compact structure and ingenious design allow for sun shading of the car anytime, anywhere after parking, effectively preventing sun exposure, reducing temperature, and minimizing the emission of harmful gases inside the vehicle. It is very convenient and practical, and highly suitable for widespread use.

[0003] The aforementioned patents occupy a large space and the installation process is complicated, requiring the disassembly and rearrangement of the vehicle's overall structure and wiring. They are difficult to adapt to various brands and types of vehicles, and both new installations and replacements require professional technicians to operate, which to some extent cannot meet actual usage needs.

[0004] Chinese patent document CN213199419U discloses a retractable car windshield sunshade device, including a fixed plate and a support plate. Suction cup assemblies are installed on the bottom surfaces of both the fixed plate and the support plate for adsorbing and fixing them to the surface of the car dashboard and the inside of the car windshield, respectively. The fixed plate has hooks on its surface. There are two support plates, each connected to a vertical plate. A damping shaft is rotatably mounted between the two vertical plates. A sunshade cloth is rolled up on the outside of the damping shaft. One side of the sunshade cloth is fixedly connected to the outside of the damping shaft, and the other side is connected to a hanging ring that cooperates with the hooks. The advantages are: the device can be fixedly installed on the inside of the car windshield, occupying little space and not affecting the driver's driving; it allows for quick unfolding and retraction of the sunshade cloth; it is simple and convenient to operate; and it has good performance.

[0005] While the aforementioned patents are easy to install and disassemble, their overall length is relatively long and takes up a lot of space when disassembled and stored. This makes them difficult to store in the relatively small space inside a vehicle and, to some extent, cannot meet the actual needs of use. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an electric sunshade that is compatible with autonomous driving technology, in order to address the shortcomings of the existing technology.

[0007] To achieve the objective of this invention, the following technical solution is adopted: an electric sunshade for use with autonomous driving technology, comprising an inner cylinder and a winding ring rotatably connected to the outer periphery of the inner cylinder; a sunshade film for blocking the sun is fixedly connected to the outer periphery of the winding ring; and a support air tube for supporting the sunshade film is provided on the sunshade film.

[0008] The inner cylinder is slidably connected to a sealing plug; the inner cylinder is rotatably connected to a lead screw that can be driven to rotate the winding ring; the lead screw is driven to slide the sealing plug.

[0009] When the lead screw rotates in the forward direction, the sealing plug slides upward, causing the inner cylinder to inflate the supporting air tube. At the same time, the winding ring rotates in the forward direction, causing the sunshade film to spread outward, thereby enabling the sunshade film to unfold and block the sun.

[0010] When the lead screw rotates in the reverse direction, the sealing plug slides downward, causing the inner cylinder to draw gas from the supporting air pipe. At the same time, the winding ring rotates in the reverse direction, causing the sunshade film to wrap around the outer circumference of the winding ring, thereby enabling the sunshade film to be retracted.

[0011] As a preferred embodiment: the upper end of the sealing plug is fixedly connected to an outer cover for housing the sunshade film on the outer periphery of the inner cylinder; a clamping ring that can abut against the lower end of the outer cover is slidably connected to the outer periphery of the inner cylinder; a first spring is provided between the clamping ring and the inner cylinder for moving the clamping ring toward the outer cover.

[0012] When the lead screw rotates in the forward direction, the sealing plug moves, causing the outer cover to separate from the clamping ring, and the sunshade film can be removed from the outer cover.

[0013] When the lead screw rotates in the reverse direction, the sealing plug moves, causing the outer cover to abut against the pressing ring. The sunshade film located between the outer cover and the pressing ring is wrapped around the outer periphery of the winding ring under the obstruction, thereby allowing the sunshade film to be housed in the outer cover.

[0014] As a preferred embodiment: a first transmission gear rotatably connected to the lower part of the inner cylinder and driven by the winding ring; a second transmission gear rotatably connected to the lower part of the inner cylinder and driven by the lead screw; and a linkage pipe rotatably connected to the lower part of the sealing plug and driven by the first transmission gear and capable of being driven by the second transmission gear.

[0015] When the sealing plug is at its upper limit position, the supporting air tube is filled with gas, the linkage tube is not in contact with the second transmission gear, the screw rotates in the opposite direction to make the sealing plug move downward, drawing gas from the supporting air tube. The downward movement of the sealing plug enables the linkage tube to be connected to the second transmission gear. The rotation of the screw synchronously drives the winding ring to rotate, winding the sunshade film.

[0016] When the sealing plug is at its lower limit position, there is no gas in the supporting air tube. The linkage tube is connected to the second transmission gear. The screw rotates in the forward direction, causing the sealing plug to move upward and inflate the supporting air tube. The rotation of the screw synchronously drives the winding ring to rotate, loosening the sunshade film. The upward movement of the sealing plug allows the linkage tube to separate from the second transmission gear. The rotation of the screw only causes the inner cylinder to inflate the supporting air tube, allowing the sunshade film to be laid out flat.

[0017] As a preferred embodiment: a first linkage hole is formed at the center of the upper end of the first transmission gear, which is slidably connected to the linkage tube; a second linkage hole is formed at the center of the upper end of the second transmission gear, which is slidably connected to the linkage tube; the cross-sections of the first linkage hole, the second linkage hole, and the linkage tube are non-circular structures with the same shape; the linkage tube can slide within the first linkage hole and the second linkage hole, and the rotation of the second linkage hole can drive the linkage tube to rotate, thereby driving the first linkage hole to rotate.

[0018] As a preferred embodiment: the outer wall of the lead screw is formed with an optical shaft with a diameter smaller than that of the lead screw near its lower end, which cannot be driven and connected to the sealing plug; a second spring is provided on the outer periphery of the lead screw for moving the sealing plug upward and thus being driven and connected to the lead screw.

[0019] When the lead screw rotates in the reverse direction, the sealing plug moves downward to the outer circumference of the optical axis, the second spring is compressed and stored, and the reverse rotation of the lead screw cannot cause the sealing plug to move downward. At this time, the outer cover can abut against the clamping ring.

[0020] When the lead screw rotates in the forward direction, the sealing plug can be pressed against the external thread on the outer circumference of the lead screw under the elastic force of the second spring, and then move upward under the guiding action of the thread of the lead screw.

[0021] As a preferred embodiment: a motor for driving the lead screw to rotate is fixedly connected inside the inner cylinder below the sealing plug; a switch for controlling the operation of the motor is provided at the upper end of the outer cover.

[0022] As a preferred embodiment: the lower end of the inner cylinder is formed with a plurality of snap-fit ​​balls; each snap-fit ​​ball is rotatably connected to a suction cup that can be adsorbed onto the glass.

[0023] As a preferred embodiment: the lower end of the inner wall of the inner cylinder is formed with an inwardly protruding snap ring; the lower end of the inner cylinder is fixedly connected with a lower cover for sealing the inner cylinder; the upper end of the lower cover is formed with a plurality of snap claws that can snap with the snap ring.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: In the initial state, the outer cover body abuts against the pressure ring, the sealing plug is located at the lower limit position, the sunshade film is sealed inside the outer cover body and wrapped around the outer periphery of the winding ring, the linkage column is inserted into the first linkage hole and the second linkage hole respectively, and the second spring is in a compressed state.

[0025] When using this product, hold the outer cover and align each suction cup with the car window. Adjust the position of the outer cover so that the sunshade film covers as much of the car window edge as possible after unfolding. Then, press each suction cup firmly onto the car window, ensuring the inner cylinder is fixed to the glass. Next, press the switch. The controller activates the motor, causing the motor gear to rotate forward. This forward rotation drives the lead screw gear to rotate forward, which in turn rotates the lead screw. The spring force of the second spring causes the threaded hole to abut against the external thread on the lead screw. The forward rotation of the lead screw guides the threaded hole upward, allowing the sealing plug to slide upward. The second spring then gradually returns to its natural length.

[0026] The upward movement of the sealing plug causes the outer casing to move upward, and the outer casing is no longer sealed by the extension ring. The upward sliding of the sealing plug reduces the volume of the inner cylinder, allowing the gas inside the inner cylinder to enter the supporting air pipe through the connecting nozzle, and the sunshade film spreads outward. Simultaneously, the forward rotation of the lead screw gear drives the second transmission gear to rotate, which in turn causes the second linkage hole to rotate. The rotation of the second linkage hole drives the linkage column to rotate, which in turn drives the first linkage hole to rotate, which in turn causes the first transmission gear to rotate. The forward rotation of the first transmission gear drives the winding gear to rotate, which in turn causes the winding ring to rotate. The rotation of the winding ring gradually loosens the sunshade film. As the lead screw continues to rotate, the winding ring releases the sunshade film, and the sunshade film spreads outward, gradually moving to the outside of the outer casing.

[0027] During this process, the sealing plug slides upward, causing the positioning pin to move upward. The upward movement of the positioning pin causes the linkage tube to move upward. The linkage tube, now no longer engaged with the second linkage hole, allows the sunshade film on the outer periphery of the winding ring to fully unfold. The lead screw continues to rotate forward, preventing the second transmission gear from driving the first transmission gear; that is, the winding ring stops rotating. The continued forward rotation of the lead screw causes the sealing plug to continue sliding upward, gradually filling the supporting air tube with gas from the inner cylinder, causing the supporting air tube to gradually expand. After a certain time T1, the controller stops the motor, the sealing plug moves to its upper limit position, and the supporting air tube expands to support the sunshade film, causing the sunshade film to unfold and straighten, attaching to the car window to block sunlight from entering the vehicle.

[0028] In practical use, users can attach this product to the side windows of a car to block sunlight, depending on the situation. For longer windshields, two products can be attached side-by-side to achieve complete sun coverage. This reduces the amount of sunlight entering the car, lowering the interior temperature after prolonged exposure to sunlight. This significantly improves the comfort of passengers and drivers, while also reducing the temperature range of the car's air conditioning, thus lowering fuel consumption and promoting energy conservation and environmental protection.

[0029] After use, press the switch again. The controller controls the motor to rotate in the opposite direction, causing the motor gear to rotate in the opposite direction. The rotating motor gear drives the lead screw to rotate in the opposite direction, and the sealing plug moves downward under the guidance of the lead screw. The volume inside the inner cylinder increases, drawing gas from the supporting air tube. The gas in the supporting air tube decreases and no longer supports the sunshade film, causing the sunshade film to shrink. The downward movement of the sealing plug drives the linkage tube to move downward, which then enters the second linkage hole. At this time, most of the gas in the supporting air tube is drawn out, and the sunshade film shrinks and closes. Then, the motor gear continues to rotate in the opposite direction, causing the second transmission gear to rotate in the opposite direction. The reverse rotation of the second transmission gear drives the first transmission gear and the winding gear to rotate in the opposite direction, causing the winding ring to rotate in the opposite direction, thus causing the sunshade film to wrap around the outer circumference of the winding ring.

[0030] During the winding of the sunshade film by the winding ring, the end of the sunshade film will rotate synchronously with the winding ring, but it cannot be tightly wrapped around the outer circumference of the winding ring, i.e., it cannot enter the outer cover. The downward movement of the sealing plug will abut against the second spring, and as the sealing plug moves downward, it will compress the second spring. After the lead screw rotates in the opposite direction for a certain time T1, the sealing plug moves downward to its lower limit position. The sealing plug moves to the outer circumference of the optical axis, and the rotation of the lead screw can no longer make the sealing plug move downward. At this time, the gas in the support air tube is completely extracted, and the downward movement of the sealing plug drives the outer cover to move downward to the initial position. The sunshade film that has not been taken into the outer cover is sandwiched between the outer cover and the pressing ring, thereby causing the pressing ring to move downward and the first spring to compress.

[0031] The screw continues to rotate in the reverse direction, causing the winding ring to wrap around the sunshade film. Due to the resistance of the clamping ring and the outer cover, the sunshade film no longer rotates synchronously with the winding ring, allowing it to fully enter the outer cover and wrap around the outer circumference of the winding ring. The clamping ring, under the elastic force of the first spring, moves upward to its original position, pressing firmly against the outer cover. After the screw rotates in the reverse direction for a certain period T2, the controller stops the motor, and the sunshade film is completely retracted into the outer cover. Then, holding the outer cover, the user pries up the suction cups along their edges to separate them from the glass, and then removes the product.

[0032] This invention features an outer cover. When the sealing plug is at its lower limit position, the outer cover abuts against the pressure ring, enclosing the sunshade film within it. The outer cover has a neat appearance, making it easy to store, and also prevents the sunshade film from being accidentally scratched or stained. When the sealing plug moves to its upper limit position, the movement of the sealing plug reduces the volume of the inner cylinder, allowing gas from the inner cylinder to enter the supporting air tube. This causes the supporting air tube to expand and support the sunshade film. Simultaneously, the outer cover moves upward, no longer being sealed by the inner cylinder. The sunshade film moves towards the outer periphery of the outer cover, allowing it to spread out flat, blocking the glass and reducing the interior temperature of the vehicle, without adding any new operating steps or structures.

[0033] This invention utilizes a lead screw. When the lead screw rotates forward, the sealing plug moves upward under the guidance of the external thread, causing the outer casing to move downward. This allows the inner cylinder to inflate the supporting air pipe. Simultaneously, the forward rotation of the lead screw also drives the winding ring to rotate forward, causing the sunshade film wound on the winding ring to gradually unwrap and thus spread out to block the sun. When the lead screw rotates in the reverse direction, it causes the sealing plug to move downward, and the winding ring to rotate in the reverse direction, causing the sunshade film to be wound up. Simultaneously, when the sealing plug reaches its lower limit position, the outer casing and the clamping ring clamp the sunshade film. The sealing plug is located on the outer circumference of the optical axis. Further reverse rotation of the lead screw cannot move the sealing plug, only the winding ring. Continued reverse rotation of the lead screw allows any remaining sunshade film not yet inside the outer casing to be completely drawn into the outer casing by the resistance of the outer casing and the clamping ring. This process requires no manual intervention, is simple and convenient to use, and saves time and effort.

[0034] This invention features a sunshade film that, when empty of gas in the supporting tube, is soft and loose, allowing it to be easily wrapped around the outer circumference of the wrapping ring, making it easy to store. When the supporting tube is filled with gas, it expands and straightens, supporting the sunshade film and allowing it to be laid flat, thus blocking sunlight and reducing the temperature inside the vehicle.

[0035] This invention can block sunlight. When placed inside a car, it can effectively block sunlight from entering the vehicle, reduce the interior temperature, and improve the comfort of passengers. This invention is easy to store, as the sunshade film can be completely retracted into the outer cover without taking up too much space. Its appearance is regular and neat, making it easy to store and organize. This invention adopts automated operation, requiring no manual intervention in the opening and closing process, making it simple, convenient, time-saving, and labor-saving.

[0046] As shown in Figures 1 to 9 Figures 1 to 9 , an electric sunshade配套 with autonomous driving technology according to this embodiment includes an inner cylinder 11 capable of adsorbing on glass and a winding ring 31 with a longitudinally arranged rotating shaft rotatably connected to the outer periphery of the inner cylinder 11; a sunshade film 32 for blocking the sun is fixedly connected to the outer periphery of the winding ring 31; a support air tube 321 for supporting the sunshade film 32 is arranged in a mesh shape on the sunshade film 32; the sunshade film 32 is made of a sunshade cloth with an aluminum coating to achieve a high reflectivity, effectively reduce the irradiation of ultraviolet rays, and effectively achieve the functions of ultraviolet protection and heat insulation.

[0047] A sealing plug 22 is hermetically and longitudinally slidably connected in the inner cylinder 11; a screw rod 41 with a longitudinally arranged rotating shaft is rotatably connected in the middle of the inner cylinder 11 and can be drivingly connected to the winding ring 31 to drive the winding ring 31 to rotate; the screw rod 41 is drivingly connected to the sealing plug 22 to drive the sealing plug 22 to longitudinally slide; a plurality of communication nozzles 113 respectively communicating with the support air tube 321 are formed at the upper end of the inner cylinder 11; an externally threaded portion is spirally formed on the outer periphery of the screw rod 41; a threaded hole 221 drivingly connected to the external thread is formed at the central position of the sealing plug 22.

[0048] When the screw rod 41 rotates forward, the threaded hole 221 slides upward under the guiding action of the external thread, and the sealing plug 22 slides upward, so that the volume of the inner cylinder 11 decreases, and then the inner cylinder 11 inflates the support air tube 321. At the same time, the winding ring 31 rotates forward, so that the sunshade film 32 spreads outwards, and the support air tube 321 inflates and expands to support the sunshade film 32, so that the sunshade film 32 can be unfolded to block the sun.

[0049] When the screw rod 41 rotates reversely, the sealing plug 22 slides downward, so that the inner cylinder 11 extracts the gas in the support air tube 321. At the same time, the winding ring 31 rotates reversely, so that the sunshade film 32 is wound around the outer periphery of the winding ring 31, so that the sunshade film 32 can be retracted.

[0050] When the sunshade film 32 is unfolded, it blocks the sun, reducing the sunlight entering the vehicle, thereby reducing the temperature inside the vehicle to a certain extent. When the driver and passengers enter the vehicle, it reduces the discomfort caused by high temperature to the driver and passengers; when the sunshade film 32 is retracted, the sunshade film 32 is wound around the outer periphery of the winding ring 31, occupying a small volume and being convenient for storage and arrangement.

[0051] The upper center of the sealing plug 22 is fixedly connected to an outer cover 21 for housing the sunshade film 32 on the outer periphery of the inner cylinder 11; a clamping ring 12 that can abut against the lower end of the outer cover 21 is slidably connected to the outer periphery of the inner cylinder 11; a plurality of first springs 13 are evenly arranged along the circumferential direction between the clamping ring 12 and the inner cylinder 11 for moving the clamping ring 12 toward the outer cover 21.

[0052] A connecting pipe is formed at the center of the upper end of the sealing plug 22, which is fixedly connected to the outer cover 21; a sealing pipe 112 is formed at the upper end of the inner wall of the inner cylinder 11, which communicates with the outside and is slidably connected to the connecting pipe; the lead screw 41 is located inside the connecting pipe; an extension ring 111 is formed at the lower end of the outer periphery of the inner cylinder 11; a plurality of sliding posts 121 are uniformly formed along the circumferential direction at the lower end of the clamping ring 12, which are slidably connected to the extension ring 111; a plurality of sliding through holes 117 are formed at the upper end of the extension ring 111, which are slidably connected to the corresponding sliding posts 121; the first spring 13 is located on the outer periphery of the corresponding sliding post 121 between the clamping ring 12 and the extension ring 111.

[0053] When the lead screw 41 rotates in the forward direction, the sealing plug 22 moves upward, causing the outer cover 21 to separate from the clamping ring 12, and the sunshade film 32 can be moved out of the outer cover 21.

[0054] When the lead screw 41 rotates in the reverse direction, the sealing plug 22 moves downward, causing the outer cover 21 to abut against the clamping ring 12. The sunshade film 32, located between the outer cover 21 and the clamping ring 12, wraps around the outer periphery of the winding ring 31 under the obstruction of the clamping ring 12 and the outer cover 21, thereby allowing the sunshade film 32 to be stored inside the outer cover 21. The outer cover 21 and the clamping ring 12 are pressed together, so that the sunshade film 32 is sealed inside the outer cover 21. The outer cover 21 has a neat appearance, is easy to store, and can also prevent the sunshade film 32 from being accidentally scratched or stained.

[0055] A first transmission gear 42, which is longitudinally arranged on a rotating shaft and is connected to the winding ring 31, is rotatably connected below the inner cylinder 11; a second transmission gear 43, which is longitudinally arranged on a rotating shaft and is connected to the lead screw 41, is rotatably connected below the inner cylinder 11; and a linkage pipe 24, which is longitudinally arranged on a rotating shaft and connected to the first transmission gear 42 and can be connected to the second transmission gear 43, is rotatably connected to the sealing plug 22 at a non-central position below it.

[0056] The lower end of the inner wall of the winding ring 31 is formed with a winding gear 311 that is connected to the first transmission gear 42; the upper center of the inner cylinder 11 is fixedly connected with an anti-detachment ring 31 that restricts the longitudinal movement of the winding ring 31; the lower non-central position of the sealing plug 22 is formed with a longitudinally arranged positioning post 222 that is rotatably connected to the linkage tube 24.

[0057] When the sealing plug 22 is at its upper limit position, the supporting air pipe 321 is filled with gas, the linkage pipe 24 is not in contact with the second transmission gear 43, the screw 41 rotates in the opposite direction to make the sealing plug 22 move downward, extracting the gas from the supporting air pipe 321. The downward movement of the sealing plug 22 enables the linkage pipe 24 to be connected to the second transmission gear 43. The rotation of the screw 41 synchronously drives the winding ring 31 to rotate, winding the sunshade film 32.

[0058] When the sealing plug 22 is at its lower limit position, there is no gas in the supporting air tube 321. The linkage tube 24 is connected to the second transmission gear 43. The screw 41 rotates in the forward direction, causing the sealing plug 22 to move upward and inflate the supporting air tube 321. The rotation of the screw 41 synchronously drives the winding ring 31 to rotate, loosening the sunshade film 32. The upward movement of the sealing plug 22 allows the linkage tube 24 to separate from the second transmission gear 43. The rotation of the screw 41 only causes the inner cylinder 11 to inflate the supporting air tube 321, causing the sunshade film 32 to be laid flat.

[0059] When the amount of gas in the supporting air tube 321 is relatively large, supporting the sunshade film 32 to lay it flat, the rotation of the lead screw 41 can only drive the sealing plug 22 to move, causing the supporting air tube 321 to inflate or deflate, but it cannot cause the winding ring 31 to rotate, that is, it cannot drive the sunshade film 32 to move, preventing the sunshade film 32 from contacting objects on the edge of the car window or the interior wall of the car. When the amount of gas in the supporting air tube 321 is small and cannot support the sunshade film 32, the rotation of the lead screw 41 drives the sealing plug 22 to move, causing the supporting air tube 321 to inflate or deflate. At the same time, the winding ring 31 rotates synchronously, winding or unwinding the sunshade film 32, saving preparation time and improving work efficiency.

[0060] The first transmission gear 42 has a first linkage hole 421 formed at the center of its upper end, which is longitudinally slidably connected to the linkage tube 24; the second transmission gear 43 has a second linkage hole 431 formed at the center of its upper end, which is longitudinally slidably connected to the linkage tube 24; the first linkage hole 421, the second linkage hole 431, and the linkage tube 24 have the same non-circular cross-section; the linkage tube 24 can slide within the first linkage hole 421 and the second linkage hole 431, and the rotation of the second linkage hole 431 can drive the linkage tube 24 to rotate, thereby driving the first linkage hole 421 to rotate.

[0061] The lower end of the inner wall of the inner cylinder 11 is formed with a gear seat 114 that is rotatably connected to the second transmission gear 43, located directly below the first transmission gear 42; the inner wall of the inner cylinder 11 is formed with a connecting groove 115 that communicates with the outside, located below the sealing plug 22; the first transmission gear 42 passes out through the connecting groove 115 and is then connected to the winding gear 311 for transmission.

[0062] The outer wall of the lead screw 41 is formed near the lower end with an optical shaft 411, which has a diameter smaller than the lead screw 41 and cannot be driven to connect with the sealing plug 22; a second spring 45 is provided on the outer periphery of the lead screw 41 for moving the sealing plug 22 upward and thus being driven to connect with the lead screw 41.

[0063] When the lead screw 41 rotates in the reverse direction, the sealing plug 22 moves downward to the outer periphery of the optical axis 411, and the second spring 45 is compressed and stored. The reverse rotation of the lead screw 41 cannot cause the sealing plug 22 to move downward. At this time, the outer cover 21 can abut against the clamping ring 12.

[0064] When the lead screw 41 rotates in the forward direction, the sealing plug 22 can abut against the external thread on the outer periphery of the lead screw 41 under the elastic force of the second spring 45, and then move upward under the thread guidance of the lead screw 41.

[0065] During the process of the lead screw 41 rotating in the reverse direction to retract the sunshade film 32, the reverse rotation of the lead screw 41 only drives the winding ring 31 to rotate. At the same time, the outer cover 21 and the pressing ring 12 can press the sunshade film 32 tightly, so that the sunshade film 32 can be completely wrapped around the outer periphery of the winding ring 31 under the obstruction. During this process, the sealing plug 22 does not move and cannot cause changes in the gas inside the supporting air tube 321. The retraction process is simple and convenient, and does not require much manual intervention.

[0066] A motor 44 for driving the lead screw 41 to rotate is fixedly connected inside the inner cylinder 11 below the sealing plug 22; a switch 23 for controlling the operation of the motor 44 is provided at the upper end of the outer cover 21.

[0067] A lead screw gear 412, which is connected to the second transmission gear 43, is fixedly connected to the center of the lower end of the lead screw 41; a motor gear 441, which is connected to the lead screw gear 412, is fixedly connected to the output shaft of the motor 44; a battery and a controller are fixedly connected to the lower part of the inner cylinder 11; the motor 44, the battery, the switch 23 and the controller are electrically connected.

[0068] The lower end of the inner cylinder 11 is uniformly formed with multiple snap-fit ​​balls 116 along the circumferential direction; each snap-fit ​​ball 116 is rotatably connected to a suction cup 15 that can be adsorbed onto the glass; most car windshields have a certain curvature, and the suction cups 15 are evenly arranged and adsorbed onto the glass, thereby fixing the inner cylinder 11 relative to the glass. When not in use, the suction cups 15 can be easily removed, and the inner cylinder 11 can be stored away, which is simple and convenient.

[0069] The lower end of the inner wall of the inner cylinder 11 is formed with an inwardly protruding snap ring 118; the lower end of the inner cylinder 11 is fixedly connected with a lower cover 51 for closing the inner cylinder 11; the upper end of the lower cover 51 is formed with a plurality of snap claws 511 along the circumferential direction that can snap with the snap ring 118.

[0070] A partition 14 is fixedly connected inside the inner cylinder 11 below the sealing plug 22; a lead screw rotation hole 142 is formed in the center of the partition 14, which is rotatably connected to the lead screw 41; the lead screw rotation hole 142 is located between the optical axis 411 and the lead screw gear 412; the second spring 45 is disposed on the outer periphery of the lead screw 41 at the upper end of the partition 14; a gear rotation hole 141 is formed at the lower end of the partition 14, which is not in the center, and is rotatably connected to the first transmission gear 42; a gear rotation concave ring 422 is formed at the upper center of the first transmission gear 42, which is rotatably connected to the gear rotation hole 141; the lower cover 51 encloses the part of the inner cylinder 11 located below the partition 14 to form an installation cavity; the motor 44, the first transmission gear 42, and the second gear 43 are located in the installation cavity.

[0071] The orientation "up" and "down" mentioned in this embodiment refer to... Figure 3 As shown, the outer cover 21 is located on top and the inner cylinder 11 is located on the bottom.

[0072] In the initial state, the outer cover 21 abuts against the clamping ring 12, the sealing plug 22 is located at the lower limit position, the sunshade film 32 is sealed inside the outer cover 21 and wrapped around the outer periphery of the winding ring 31, the linkage column 24 is inserted into the first linkage hole 421 and the second linkage hole 431 respectively, and the second spring 45 is in a compressed state.

[0073] When using this product, hold the outer cover 21 with your hand, align each suction cup 15 with the car glass, and adjust the position of the outer cover 21 so that the sunshade film 32, after unfolding, can cover as much of the edge of the car glass as possible. Then, press each suction cup 15 firmly onto the car glass, and the suction cups 15 will hold the glass firmly, fixing the inner cylinder 11 relative to the car glass. Next, press the switch 23. The controller controls the motor 44 to work, causing the motor gear 441 to rotate forward. The forward rotation of the motor gear 441 drives the lead screw gear 412 to rotate forward, which in turn causes the lead screw 41 to rotate forward. The elasticity of the second spring 45 causes the threaded hole 221 to abut against the external thread on the outer circumference of the lead screw 41. The forward rotation of the lead screw 41 causes the threaded hole 221 to move upward under the guidance of the external thread, thus causing the sealing plug 22 to slide upward. The second spring 45 gradually returns to its natural length.

[0074] The upward movement of the sealing plug 22 causes the outer cover 21 to move upward, and the outer cover 21 is no longer sealed by the extension ring 111. The upward sliding of the sealing plug 22 reduces the volume of the inner cylinder 11, and the gas inside the inner cylinder 11 enters the supporting air pipe 321 through the connecting nozzle 113, causing the sunshade film 32 to spread outward. At the same time, the forward rotation of the lead screw gear 412 drives the second transmission gear 43 to rotate, which in turn causes the second linkage hole 431 to rotate in the forward direction. The forward rotation of the second linkage hole 431 drives the linkage column 24 to rotate, which in turn drives the first linkage hole 421 to rotate, which in turn causes the first transmission gear 42 to rotate in the forward direction. The forward rotation of the first transmission gear 42 drives the winding gear 311 to rotate in the forward direction, which in turn causes the winding ring 31 to rotate in the forward direction. The forward rotation of the winding ring 31 gradually loosens the sunshade film 32. As the lead screw 41 continues to rotate, the winding ring 31 releases the sunshade film 32, and at the same time, the sunshade film 32 spreads outward, causing the sunshade film 32 to gradually move to the outside of the outer cover 21.

[0075] During this process, the sealing plug 22 slides upward, causing the positioning pin 222 to move upward. The upward movement of the positioning pin 222 causes the linkage tube 24 to move upward. The upward movement of the linkage tube 24 will no longer be connected to the second linkage hole 431. At this time, the sunshade film 32 on the outer periphery of the winding ring 31 is fully spread outward. The screw 41 continues to rotate in the forward direction, preventing the second transmission gear 43 from driving the first transmission gear 42 to rotate. That is, the winding ring 31 stops rotating. The screw 41 continues to rotate in the forward direction, causing the sealing plug 22 to continue to slide upward. The gas in the inner cylinder 11 gradually fills the supporting air tube 321, causing the supporting air tube 321 to gradually expand. After a certain time T1, the controller controls the motor 44 to stop working. The sealing plug 22 moves to the upper limit position, and the supporting air tube 321 expands to support the sunshade film 32, causing the sunshade film 32 to spread out and straighten. The sunshade film 32 is attached to the car glass to block sunlight from entering the car.

[0076] In practical use, users can attach this product to the side windows of a car to block sunlight, depending on the situation. For longer windshields, two products can be attached side-by-side to achieve complete sun coverage. This reduces the amount of sunlight entering the car, lowering the interior temperature after prolonged exposure to sunlight. This significantly improves the comfort of passengers and drivers, while also reducing the temperature range of the car's air conditioning, thus lowering fuel consumption and promoting energy conservation and environmental protection.

[0077] After use, press switch 23 again. The controller controls motor 44 to work, causing motor gear 441 to rotate in the opposite direction. The reverse rotation of motor gear 441 drives lead screw 41 to rotate in the opposite direction. Under the guidance of lead screw 41, sealing plug 22 moves downward, increasing the volume inside inner cylinder 11 and drawing gas from supporting air pipe 321. The gas in supporting air pipe 321 decreases, no longer supporting sunshade film 32, causing sunshade film 32 to shrink. The downward movement of sealing plug 22 drives linkage pipe 24 to move downward, allowing linkage pipe 24 to enter the second linkage hole 431. At this time, most of the gas in supporting air pipe 321 is drawn out, and sunshade film 32 shrinks and closes. Then, motor gear 441 continues to rotate in the opposite direction, causing second transmission gear 43 to rotate in the opposite direction. The reverse rotation of second transmission gear 43 sequentially drives first transmission gear 42 and winding gear 311 to rotate in the opposite direction, causing winding ring 31 to rotate in the opposite direction, thus causing sunshade film 32 to wrap around the outer circumference of winding ring 31.

[0078] During the process of the winding ring 31 winding the sunshade film 32, the end of the sunshade film 32 will rotate synchronously with the winding ring 31 and cannot be tightly wrapped around the outer circumference of the winding ring 31, that is, it cannot enter the outer cover 21. The downward movement of the sealing plug 22 will abut against the second spring 45, and as the sealing plug 22 moves downward, the second spring 45 will be compressed. After the lead screw 41 rotates in the opposite direction for a certain time T1, the sealing plug 22 moves downward to the lower limit position. The sealing plug 22 moves to the outer circumference of the optical axis 411, and the rotation of the lead screw 41 can no longer make the sealing plug 22 continue to move downward. At this time, the gas in the support air tube 321 is completely extracted, and the downward movement of the sealing plug 22 drives the outer cover 21 to move downward to the initial position. The sunshade film 32 that has not been taken into the outer cover 21 is sandwiched between the outer cover 21 and the pressing ring 12, thereby causing the pressing ring 12 to move downward and the first spring 13 to be compressed.

[0079] The lead screw 41 continues to rotate in the reverse direction, causing the winding ring 31 to wrap around the sunshade film 32. Under the resistance of the clamping ring 12 and the outer cover 21, the sunshade film 32 no longer rotates synchronously with the winding ring 31, allowing it to fully enter the outer cover 21 and wrap around the outer circumference of the winding ring 31. The clamping ring 12 moves upward to its original position under the elastic force of the first spring 13, and the clamping ring 12 abuts against the outer cover 21. After the lead screw 41 rotates in the reverse direction for a certain period T2, the controller stops the motor 44, and the sunshade film 32 is fully retracted into the outer cover 21. Then, the outer cover 21 is held by hand, and the suction cup 15 is lifted along its edge to separate it from the glass. The product is then removed.

[0080] This invention, by setting an outer cover 21, when the sealing plug 22 is at its lower limit position, the outer cover 21 abuts against the pressing ring 12, so that the sunshade film 32 is sealed inside the outer cover 21. The outer cover 21 has a neat appearance and is easy to store, while also preventing the sunshade film 32 from being accidentally scratched or stained. When the sealing plug 22 moves to its upper limit position, the movement of the sealing plug 22 reduces the volume inside the inner cylinder 11, and the gas inside the inner cylinder 11 enters the supporting air pipe 321, causing the supporting air pipe 321 to expand and support the sunshade film 32. At the same time, the outer cover 21 moves upward synchronously, so that the outer cover 21 is no longer sealed by the inner cylinder 11, and the sunshade film 32 moves to the outer periphery of the outer cover 21, thereby allowing the sunshade film 32 to spread out flat, block the glass, and reduce the temperature inside the vehicle, without adding any new operating steps or structures.

[0081] This invention utilizes a lead screw 41. When the lead screw 41 rotates forward, the sealing plug 22 moves upward under the guidance of the external thread, causing the outer cover 21 to move downward. The inner cylinder 11 then inflates the supporting air pipe 321. Simultaneously, the forward rotation of the lead screw 41 also drives the winding ring 31 to rotate forward, causing the sunshade film 32 wound on the winding ring 31 to gradually unwrap, thus allowing the sunshade film 32 to spread out and block the sun. When the lead screw 41 rotates in the reverse direction, it causes the sealing plug 22 to move downward, and the winding ring 31 rotates in the reverse direction, causing... The sunshade film 32 is wound up and retracted. At the same time, when the sealing plug 22 moves to the lower limit position, the outer cover 21 and the clamping ring 12 clamp the sunshade film 32. The sealing plug 22 is located on the outer periphery of the optical axis 411. The screw 41 continues to rotate in the opposite direction, which cannot make the sealing plug 22 move, but can only make the winding ring 31 rotate. The screw 41 continues to rotate in the opposite direction, so that the sunshade film 32 that is not retracted into the outer cover 21 is completely retracted into the outer cover 21 under the obstruction of the outer cover 21 and the clamping ring 12. No manual intervention is required. It is simple and convenient to use, saving time and effort.

[0082] The present invention provides a sunshade film 32. When there is no gas in the supporting air tube 321, the sunshade film 32 is soft and loose, and can be easily wrapped around the outer periphery of the wrapping ring 31, making the sunshade film 32 easy to store. When the supporting air tube 321 is filled with gas, the supporting air tube 321 expands and straightens, thereby supporting the sunshade film 32, allowing the sunshade film 32 to be laid flat and spread out, thereby blocking sunlight and reducing the temperature inside the vehicle.

[0083] This invention can block sunlight. When placed inside a car, it can effectively block sunlight from entering the vehicle, reduce the interior temperature, and improve the comfort of passengers. This invention is easy to store, as the sunshade film can be completely retracted into the outer cover without taking up too much space. Its appearance is regular and neat, making it easy to store and organize. This invention adopts automated operation, requiring no manual intervention in the opening and closing process, making it simple, convenient, time-saving, and labor-saving.
