Description

Technical Field

[0001] This invention relates to the field of functional film installation, and more specifically to a side window functional film installation device. Background Technology

[0002] Functional films, as a novel type of smart material, possess a variety of functional properties, such as light modulation, heat insulation, UV protection, explosion protection, conductivity, and sound insulation. They have been widely used in architectural glass, automotive glass, electronic displays, and decorative materials. Functional films typically employ a multi-layered composite structure, dynamically switching functions by adjusting electric fields, light, or other physical parameters to meet the application needs of different scenarios.

[0003] In the application scenario of vehicle side windows, the installation of functional films can effectively improve the quality of the in-vehicle environment. For example, heat-insulating films can reduce the transfer of solar radiation heat and improve the efficiency of the vehicle's air conditioning; UV-protective films can protect occupants from UV damage and delay the aging of interior materials; while sound-insulating films can significantly reduce outside noise and improve driving comfort. As people's requirements for vehicle comfort, privacy, and safety continue to increase, the demand for functional films on automotive side windows continues to grow.

[0004] However, vehicle side windows typically have a certain degree of curvature or tilt, and the functional film itself is soft and thin, making it susceptible to external environmental factors (such as wind and static electricity) during installation. This makes it difficult to guarantee the flatness and adhesion quality of the film during positioning and application. Traditional manual installation methods for functional films have the following problems:

[0005] Because the functional membrane is thin, it is easily affected by environmental wind or static electricity, making it difficult to ensure the flatness and accuracy of the membrane during manual positioning.

[0006] During the application of the film, uneven manual smoothing techniques can easily leave air bubbles between the film and the window surface, which can damage the function of the film.

[0007] Manual film application is slow and requires highly experienced technicians, which is not conducive to large-scale and efficient construction.

[0008] In the current manual installation process, it is difficult to achieve a smooth, gradual fit of the functional membrane from the center to the edge, which can easily lead to localized lifting or unevenness of the membrane. Summary of the Invention

[0009] To address the aforementioned issues, this invention provides a side window functional film installation device that combines negative pressure adsorption, elastic scraper, and telescopic clamping structure. This not only effectively prevents air bubble formation but also solves the problem of low efficiency in manual installation, and can be widely applied to the installation of side window functional films.

[0010] This invention is achieved through the following technical solution: a side window functional film installation device, comprising:

[0011] The positioning and mounting cylinder has a mounting cavity inside, and the bottom surface of the positioning and mounting hole that contacts the functional membrane is a negative pressure adsorption surface.

[0012] At least four telescopic clamping arms, one end of each telescopic clamping arm is connected to the positioning and mounting cylinder through an elastic hinge mechanism, and the other end of each arm is provided with a clamping mechanism. The clamping mechanism of the at least four telescopic clamping arms clamps the four corners of the functional film, so that the two ends of the clamped functional film are raised relative to the negative pressure adsorption surface and form an angle α with the window surface to be bonded.

[0013] Two elastic scrapers are located on both sides of the positioning and mounting cylinder, and the elastic scrapers are both located between the functional membrane and the telescopic clamping arm. Each elastic scraper is connected to the positioning and mounting cylinder through a telescopic ejection mechanism, and each elastic scraper is arc-shaped and contracted when not in use, and is wrapped and installed in the annular storage cavity opened at the bottom of the positioning cylinder.

[0014] An extrusion drive mechanism is installed inside the positioning and mounting cylinder and is connected in communication with the telescopic ejection mechanism.

[0015] When the functional film is installed, the elastic scraper expands elastically from an arc-shaped contracted state until it makes contact with the inner side of the window frame. The expanded elastic scraper is then driven by the extrusion drive mechanism to move along the length of the functional film, thus adhering the functional film to the window surface.

[0016] As a preferred technical solution, a magnetic layer is provided on the upper surface of the elastic scraper, and multiple magnetic blocks are arranged on the bottom surface of the telescopic clamping arm opposite to the magnetic layer along the length of the telescopic clamping arm. When the elastic scraper is driven by the extrusion driving mechanism, the elastic scraper attracts the magnetic blocks at the top and continuously reduces the included angle α.

[0017] The bottom of the elastic scraper is provided with a flexible contact layer. The magnetic force of the magnetic block is the smallest on the side away from the negative pressure adsorption surface, and gradually increases as it moves away from the negative pressure adsorption surface.

[0018] As a preferred technical solution, the outer circular surface of the positioning and mounting cylinder is provided with an annular mounting cavity at the upper end near the annular storage cavity, and each telescopic clamping arm is installed in the annular mounting cavity through the elastic hinge mechanism.

[0019] As a preferred technical solution, each of the elastic hinge mechanisms includes a fixed screw fixed in the annular mounting cavity, a rotating sleeve mounted on the fixed screw, a hinge bracket provided at one end of the rotating sleeve, and the telescopic clamping arms are elastically hinged to the hinge bracket through a hinge rod and a torsion spring. A locking nut is installed on the top of the fixed screw to lock the rotating sleeve.

[0020] As a preferred technical solution, each telescopic clamping arm includes a telescopic sleeve, a first telescopic rod, and a second telescopic rod. The telescopic sleeve has a telescopic mounting cavity. One end of the first telescopic rod and the second telescopic rod are telescopically inserted into the telescopic mounting cavity. A locking screw is provided on each side of the telescopic sleeve corresponding to the positions of the first telescopic rod and the second telescopic rod. The locking screws are used to position the first telescopic rod and the second telescopic rod within the telescopic sleeve. The clamping mechanism is provided on the second telescopic rod.

[0021] As a preferred technical solution, a metal suction block is embedded in the inner side of both ends of the elastic scraper, and an electromagnet is provided on both sides of the annular storage cavity corresponding to the position of the metal suction block. When the elastic scraper is not in use, the elastic scraper is magnetically attracted to the electromagnet through the metal suction block.

[0022] As a preferred technical solution, the extrusion drive mechanism includes an extrusion cylinder, an elastic air reservoir is installed on the inner end of the extrusion cylinder, the extrusion cylinder is movably installed inside the positioning and mounting cylinder and extends outside the positioning and mounting cylinder, and the elastic air reservoir is connected to the telescopic ejection mechanism through an air guide pipe.

[0023] As a preferred technical solution, the telescopic ejection mechanism comprises multiple telescopic sleeves with different outer diameters. The telescopic ejection mechanism is installed in a mounting groove opened on the bottom surface of the positioning mounting cylinder. One end of the telescopic ejection mechanism is fixedly connected to the inner wall of the mounting groove, and the other end passes through the positioning mounting cylinder and is fixedly connected to the center position of the elastic scraper. The elastic air storage bag is connected to the telescopic sleeve with the largest outer diameter through the air guide pipe. By squeezing the elastic air storage bag, the gas in the elastic air storage bag enters into each telescopic sleeve through the air guide pipe, and the gas drives the stretching between each telescopic sleeve to eject the elastic scraper.

[0024] A spring is also installed on the outside of the telescopic ejection mechanism. One end of the spring is fixedly connected to the inner side of the elastic scraper, and the other end of the spring is fixedly connected to the end face of the telescopic sleeve with the maximum outer diameter.

[0025] As a preferred technical solution, a gripping operation part is also fixedly installed on the outside of the positioning and mounting cylinder;

[0026] Each clamping mechanism includes an elastic clamping piece. One end of the elastic clamping piece is fixedly connected to the telescopic clamping arm, and the other end of the elastic clamping piece is a snap-in end. Positioning pins are also provided on both sides of the bottom of the elastic clamping piece. When clamping the functional film, a clamping protrusion is formed at the clamping position of the functional film. The clamping protrusion is snapped into the elastic clamping piece and positioned by the positioning pins.

[0027] As a preferred technical solution, the negative pressure adsorption surface is provided with multiple negative pressure suction holes, a negative pressure pump is installed in the mounting cavity of the positioning mounting cylinder, the suction end of the negative pressure pump is connected and conductive to each negative pressure suction hole, a control main board is embedded in the top of the extrusion drive mechanism, and a control button is also provided on the upper surface of the control main board. The control main board is connected to the electromagnet and the negative pressure pump, and the switch is controlled by the control button. A rechargeable battery is also installed on one side of the negative pressure pump, and the rechargeable battery supplies power to the negative pressure pump and the battery iron. A support partition is provided on the top of the negative pressure pump.

[0028] The beneficial effects of the present invention are as follows: The present invention provides a side window functional film installation device, which uses a negative pressure adsorption surface as an adsorption point to make the central area of ​​the functional film contact and support the window surface first, and uses four telescopic clamping arms to clamp the four corners of the functional film, so that the non-central area of ​​the functional film is lifted up, avoiding direct contact with the window surface in the initial stage of film application, thereby effectively reducing the possibility of air bubbles, and making the functional film straight and flat during film application, which is convenient for operation.

[0029] The elastic scraper in the device of the present invention is in an arc-shaped contracted state when not in use, and opens in an arc shape when the film is applied. The arc-shaped open elastic scraper is used to scrape the center position of the functional film, first applying the film to the center position. Then, the elastic scraper is driven by the extrusion drive mechanism to move along the length of the functional film, gradually scraping the functional film from the center to both sides to make it smoothly adhere to the window surface.

[0030] Furthermore, the elastic scraper and the telescopic clamping arm are magnetically attracted to each other. As the scraper moves, it gradually drives the telescopic clamping arm to descend, thereby achieving the gradual adhesion of the functional film from the center to the edge, further improving the flatness and quality of the film application.

[0031] This device replaces manual installation with automated operation, solving the problems of air bubbles and curling edges caused by inaccurate positioning and uneven application during traditional manual film application, while significantly improving work efficiency.

Detailed Implementation

[0042] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0043] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0044] like Figure 1 and Figure 2 As shown, a side window functional film installation device of the present invention includes a positioning installation cylinder 8, which has an installation cavity 27 inside, and the bottom surface of the positioning installation hole that contacts the functional film 2 is a negative pressure adsorption surface 26. During installation, the center adsorption position of the functional film 2 is first found, and then the adsorption surface of the positioning installation cylinder 8 is attached to the adsorption position to achieve negative pressure adsorption, thereby positioning the center area.

[0045] Please continue reading. Figure 1 and Figure 2 It also includes four telescopic clamping arms 100. One end of each telescopic clamping arm 100 is connected to the positioning and mounting cylinder 8 through an elastic hinge mechanism 14, and the other end is provided with a clamping mechanism 15. The clamping mechanisms 15 of at least four telescopic clamping arms 100 clamp the four corners of the functional film 2, so that the two ends of the clamped functional film 2 are raised relative to the negative pressure adsorption surface 26 and form an angle α with the window surface 3 to be attached. After the four corners of the functional film 2 are clamped, the four corners of the functional film 2 are stretched and the center position is negatively adsorbed, thereby tightening the entire functional film 2. Since the four corners of the functional film 2 are raised, when the functional film 2 contacts the window surface 3, only the center adsorption position is in contact and adsorbed, while the other positions of the functional film 2 are not in contact. Thus, it is only necessary to align the center adsorption position of the functional film 2 with the center position of the window surface 3 for positioning. When installing the functional film 2, it is necessary to tighten the functional film 2.

[0046] like Figure 2 and Figure 3 As shown, it also includes two elastic scrapers 9, located on both sides of the positioning and mounting cylinder 8, and the elastic scrapers 9 are both located between the functional membrane 2 and the telescopic clamping arm 100. Each elastic scraper 9 is connected to the positioning and mounting cylinder 8 through a telescopic ejection mechanism 23. When not in use, each elastic scraper 9 is wrapped in an arc-shaped contraction and installed in the annular storage cavity 16 opened at the bottom of the positioning cylinder. Once in use, the elastic scraper 9 can be expanded in an arc shape to achieve the rotation of the central area to both sides, thereby achieving a tight fit at the central position.

[0047] It also includes a compression drive mechanism, which is installed in the positioning and mounting cylinder 8 and is connected to the telescopic ejection mechanism 23. When the functional film 2 is positioned at the center of the window surface 3, the compression drive mechanism can be driven by compression, which causes the telescopic ejection mechanism 23 to extend after air intake, thereby driving the elastic scraper 9 to move and push from the middle to both sides, so as to flatten the functional film 2 from the center to both sides.

[0048] When the functional film 2 is installed, the elastic scraper 9 expands elastically from its arc-shaped contracted state until it makes guide contact with the inner side of the window frame 10. The expanded elastic scraper 9 is driven by the extrusion drive mechanism to move along the length of the functional film 2, thus adhering the functional film 2 to the window surface 3. In order to increase the contact stability with the window frame 10, guide wheels 11 can be installed on both ends of the elastic scraper 9. The protruding guide wheels 11 contact and guide the window frame 10, thereby enabling the elastic scraper 9 to move along the functional film 2 to achieve the purpose of scraping the film.

[0049] like Figure 1 As shown, a magnetic layer 28 is provided on the upper surface of the elastic scraper 9. Multiple magnetic blocks are arranged along the length of the telescopic clamping arm 100 on the side of the bottom surface opposite to the magnetic layer 28. When the elastic scraper 9 is driven by the extrusion drive mechanism, the elastic scraper 9 attracts the magnetic blocks at the top and continuously reduces the included angle α. When the elastic scraper 9 moves continuously along both ends of the functional membrane 2, it attracts the telescopic clamping arm 100 by magnetic force, causing the telescopic clamping arm 100 to continuously descend and causing the functional membrane 2 at the bottom to continuously adhere to the window surface 3, and the included angle α gradually decreases.

[0050] In this embodiment, a flexible contact layer is provided at the bottom of the elastic scraper 9. The flexible contact layer can be made of materials such as cloth, and should be smooth and non-sticky when in contact with the functional membrane 2. In order to ensure that the elastic scraper 9 can always adhere to the telescopic clamping arm 100 at the top and prevent the magnetic attraction force from being affected due to excessive distance, in this embodiment, the magnetic force of the magnetic block is the smallest on the side away from the negative pressure adsorption surface 26, and gradually increases as it moves away from the negative pressure adsorption surface 26.

[0051] like Figure 2 and Figure 3As shown, an annular mounting cavity 727 is provided on the outer circular surface of the positioning mounting cylinder 8 near the upper end of the annular receiving cavity 16. Each telescopic clamping arm 100 is mounted in the annular mounting cavity 727 through the elastic hinge mechanism 14. The elastic hinge mechanism 14 includes a fixing screw 143 fixed in the annular mounting cavity 727. A rotating shaft sleeve 142 is mounted on the fixing screw 143. A hinge bracket 146 is provided at one end of the rotating shaft sleeve 142. Each telescopic clamping arm 100 is connected to the hinge bracket through a hinge rod 145 and a torsion spring 24. 146. The fixed screw 143 is elastically hinged, and a locking nut 141 is installed on the top of the fixed screw 143. The rotating shaft sleeve 142 is locked by the locking nut 141. When clamping the functional film 2, the length of each telescopic clamping arm 100 is adjusted according to the shape and size of the functional film 2. Then the rotation angle of the telescopic clamping arm 100 is adjusted. During adjustment, the locking nut 141 can be loosened. Since the torsion spring 24 is provided, the telescopic clamping arm 100 is always kept in a tilted state under the action of the torsion spring 24, so that the functional film 2 can tilt up at both ends after clamping and does not contact the window surface 3.

[0052] like Figure 2 As shown, each telescopic clamping arm 100 includes a telescopic sleeve 5, a first telescopic rod 6, and a second telescopic rod 4. The telescopic sleeve 5 has a telescopic mounting cavity 5127. One end of the first telescopic rod 6 and the second telescopic rod 4 are telescopically inserted into the telescopic mounting cavity 5127. A locking screw is provided on each side of the telescopic sleeve 5 at the position corresponding to the first telescopic rod 6 and the second telescopic rod 4. The locking screws are used to position the first telescopic rod 6 and the second telescopic rod 4 within the telescopic sleeve 5. The clamping mechanism 15 is provided on the second telescopic rod 4. The locking screws are used to achieve relative stretching between the telescopic rods and positioning after stretching.

[0053] like Figure 3 As shown, a metal suction block is embedded in the inner surface of both ends of the elastic scraper 9. An electromagnet 17 is provided on both sides of the annular storage cavity 16 corresponding to the position of the metal suction block. When the elastic scraper 9 is not in use, the elastic scraper 9 is magnetically attracted to the electromagnet 17 through the metal suction block. When the electromagnet 17 is energized, the electromagnet 17 always attracts the metal suction block of the elastic scraper 9. At this time, the elastic scraper 9 is in an elastic deformation state. After the power supply of the electromagnet 17 is disconnected, the elastic scraper 9 elastically opens, thereby realizing the arc-shaped scraping. In this embodiment, the elastic scraper 9 can be a shape memory metal material.

[0054] like Figure 4 and Figure 6As shown, the extrusion drive mechanism includes an extrusion cylinder 1, an elastic air reservoir 20 is installed on the inner end of the extrusion cylinder 1, the extrusion cylinder 1 is movably installed inside the positioning mounting cylinder 8 and extends outside the positioning mounting cylinder 8, and the elastic air reservoir 20 is connected to the telescopic ejection mechanism 23 through an air guide pipe 22.

[0055] Each telescopic ejection mechanism 23 consists of multiple telescopic sleeves 5 with different outer diameters. The telescopic ejection mechanism 23 is installed in the mounting groove 19 opened on the bottom surface of the positioning mounting cylinder 8. One end of the telescopic ejection mechanism 23 is fixedly connected to the inner wall of the mounting groove 19, and the other end passes through the positioning mounting cylinder 8 and is fixedly connected to the center position of the elastic scraper 9. The elastic air storage bladder 20 is connected to the telescopic sleeve 5 with the largest outer diameter through the air guide pipe 22. By squeezing the elastic air storage bladder 20, the gas in the elastic air storage bladder 20 enters into each telescopic sleeve 5 through the air guide pipe 22, and the gas drives the stretching between each telescopic sleeve 5 to eject the elastic scraper 9.

[0056] A spring 24 is also installed on the outside of the telescopic ejection mechanism 23. One end of the spring 24 is fixedly connected to the inner side of the elastic scraper 9, and the other end of the spring 24 is fixedly connected to the end face of the telescopic sleeve 5 with the largest outer diameter. When the telescopic ejection mechanism 23 is extended due to the filling of gas, the spring 24 will also be stretched. Once the pressure on the elastic air bladder 20 is removed, the telescopic ejection mechanism 23 can be reset by the spring 24. In this embodiment, the telescopic ejection mechanism 23 is similar to the telescopic antenna structure in the prior art. However, it is necessary to ensure the sealing of the contact between the inner and outer ends of each telescopic sleeve 5. Therefore, when each telescopic sleeve 5 is nested with each other, an annular sealing piston ring can be set at the contact surface to achieve the sealing nesting of adjacent telescopic sleeves 5. After the telescopic ejection mechanism 23 is filled with gas, the gas can be used to stretch the entire telescopic ejection mechanism 23 to achieve the purpose of ejecting the elastic scraper 9.

[0057] In this embodiment, for ease of operation, a gripping operation part 12 is also fixedly installed on the outside of the positioning and mounting cylinder 8.

[0058] like Figure 7 As shown, each clamping mechanism 15 includes an elastic clamping piece 41. One end of the elastic clamping piece 41 is fixedly connected to the telescopic clamping arm 100, and the other end of the elastic clamping piece 41 is a snap-in end 42. Positioning pins 43 are also provided on both sides of the bottom of the elastic clamping piece 41. When clamping the functional film 2, a clamping protrusion is formed at the clamping position of the functional film 2. The clamping protrusion is snapped into the elastic clamping piece 41 and positioned by the positioning pins 43. The clamping protrusion can be manually cut off with a knife after the film is applied. During installation, the positioning pins 43 pass through the clamping protrusion to complete the positioning and clamping.

[0059] like Figures 4-6 As shown, a plurality of negative pressure suction holes 25 are provided on the negative pressure adsorption surface 26. A negative pressure pump 21 is installed in the mounting cavity 27 of the positioning mounting cylinder 8. The suction end of the negative pressure pump 21 is connected and communicated with each negative pressure suction hole 25. A control main board is embedded in the top of the extrusion drive mechanism. A control button 13 is also provided on the upper surface of the control main board. The control main board is connected to the electromagnet 17 and the negative pressure pump 21. The switch is controlled by the control button 13. A rechargeable battery is also installed on one side of the negative pressure pump 21. The rechargeable battery supplies power to the negative pressure pump 21 and the battery iron. A support partition 18 is provided on the top of the negative pressure pump 21.

[0060] This invention provides a side window functional film 2 installation device. The negative pressure adsorption surface 26 is used as the adsorption point, so that the central area of ​​the functional film 2 first contacts and supports the window surface 3. The four telescopic clamping arms 100 are used to clamp the four corners of the functional film 2, so that the non-central area of ​​the functional film 2 is lifted up, avoiding direct contact with the window surface 3 in the initial stage of film application, thereby effectively reducing the possibility of air bubbles. This allows the functional film 2 to be laid straight and flat during film application, which is convenient for operation.

[0061] The elastic scraper 9 in the device of the present invention is in an arc-shaped contracted state when not in use, and opens in an arc shape when the film is applied. The arc-shaped open elastic scraper 9 is used to scrape the center position of the functional film 2. First, the center position is adhered. Then, the elastic scraper 9 is driven by the extrusion drive mechanism to move along the length direction of the functional film 2, and gradually scrapes the functional film 2 from the center to both sides to make it adhere smoothly to the window surface 3.

[0062] Furthermore, the elastic scraper 9 and the telescopic clamping arm 100 are magnetically attracted to each other. As the scraper moves, it gradually drives the telescopic clamping arm 100 to descend, thereby achieving the gradual adhesion of the functional film 2 from the center to the edge, further improving the flatness and quality of the film application.

[0063] This device replaces manual installation with automated operation, solving the problems of air bubbles and curling edges caused by inaccurate positioning and uneven application during traditional manual film application, while significantly improving work efficiency.

[0064] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
