Description

Technical Field

[0001] This utility model relates to the technical field of car window tinting tools, specifically, to a car window tinting auxiliary tool with positioning and supplementary lighting functions. Background Technology

[0002] In the field of automotive decoration and protection, window tinting is a common procedure, combining the enhancement of a vehicle's aesthetics with practical functions such as heat insulation, UV protection, and privacy protection. Currently, window tinting primarily relies on manual operation. The process involves cutting or trimming rolls of film to fit the shape of the window glass. The film is first placed on the outer surface of the window, and the two are precisely positioned. Then, a utility knife is used to cut or trim the film to the appropriate shape along the edge of the window. Finally, the cut film is applied to the inner side of the window to ensure a tight fit without bubbles or wrinkles. However, traditional tinting methods rely mainly on the operator's experience and simple measuring tools for positioning and cutting, lacking reliable auxiliary devices. For example, Chinese Patent CN202020415995.9, which proposes a "conveniently positioned automotive window tinting device," while helpful for positioning the sun protection film to some extent, still cannot fully meet the requirements for precise positioning and cutting. This results in low positioning accuracy, easy deviation, and consequently affects the tinting effect and aesthetics.

[0003] Furthermore, in poorly lit working environments, especially in areas with poor visibility such as the edges of car windows, operators find it difficult to clearly observe the details of the film's adhesion to the window edges. When applying film in dimly lit places like underground parking garages, even with simple lighting, it's difficult to observe the edges of the window glass. The cut edges of the film may not match the final adhesion to the window glass, leading to peeling, and the accumulation of air bubbles, dust, or impurities, significantly impacting the quality and efficiency of the application. Most existing car window film application tools focus on only one function. For example, Chinese patent CN218617377U, "A Film Application Tool with a UV Lamp," only improves the film positioning assistance and subsequent UV lamp illumination functions. Similarly, Chinese patent CN202220262830, "A Conveniently Positioned Car Window Film Application Device," only optimizes positioning and clamping, failing to simultaneously meet the dual requirements of precise positioning and cutting, and good lighting during the film application process. Therefore, developing a car window film application tool that can effectively solve the above problems and integrate positioning and supplementary lighting functions, as described in this utility model, has important practical significance and application value. Utility Model Content

[0004] The purpose of this utility model is to provide a window film application auxiliary tool with positioning and supplementary lighting functions, so as to solve the problem mentioned in the background art that it is difficult for operators to clearly observe the details of the film application in working environments with insufficient light, especially in areas with poor visibility such as the edges of the window glass.

[0005] To achieve the above objectives, this utility model provides a car window tinting auxiliary tool with positioning and supplemental lighting functions, including an outer moving part and an inner moving part. The outer moving part is located on the outer side of the car window glass, and the inner moving part is located on the inner side of the car window glass. The outer moving part and the inner moving part are magnetically attracted to each other through the car window glass. A light guide plate is detachably installed on one side of the inner moving part, and a light source is installed inside the inner moving part near the end of the light guide plate. The light from the light source is guided by the light guide plate to illuminate the edge of the car window.

[0006] This design features an outer movable component located on the outer side of the window glass and an inner movable component located on the inner side. The two components are magnetically attracted to each other, utilizing the penetrating and attractive properties of magnetism to achieve a tight fit through the window glass, forming a stable positioning structure. Simultaneously, a light source is installed within the inner movable component. The light is transmitted through a detachable light guide plate, whose optical properties precisely guide the light to the edge of the window, facilitating the cutting of the film material according to the window's shape.

[0007] Preferably, the outer movable component includes an outer shell with an outer magnetic absorbing plate installed at the bottom of the outer shell, and the inner movable component includes an inner shell with an inner magnetic absorbing plate installed at the top of the inner shell. The outer magnetic absorbing plate and the inner magnetic absorbing plate are attracted to each other by magnetic attraction.

[0008] This design features an outer magnetic clasp mounted on the bottom of the outer housing of the outer movable component, and an inner magnetic clasp mounted on the top of the inner housing of the inner movable component. The outer and inner magnetic clasps attract each other magnetically. The magnetic force allows the two movable components to adhere firmly to both sides of the car window glass, and the magnetic force is moderate enough to ensure stable adhesion while facilitating position adjustment during operation.

[0009] Preferably, both the outer and inner movable parts are provided with anti-slip strips on their outer walls.

[0010] This feature incorporates anti-slip strips on the outer and inner walls of the moving parts. The textured surface of these strips increases friction between the tool and the operator's hand. Based on the principle of friction, the rough surface effectively prevents the tool from slipping from the hand during use.

[0011] Preferably, one side of the inner movable component has an insertion interface, and one end of the light guide plate is inserted into the insertion interface.

[0012] This design features an insertion interface on one side of the inner movable component, with one end of the light guide plate engaging with the interface via a plug-in connection. This structure is based on mechanical connection principles, allowing for the installation and removal of the light guide plate and the inner movable component through plugging and unplugging. The shape of the insertion interface matches the end of the light guide plate, ensuring a tight and stable connection.

[0013] Preferably, a clamping member is installed inside the inner movable member near the light source, and one end of the light guide plate passes through the insertion interface and is clamped and fixed by the clamping member.

[0014] This feature includes a clamping component installed inside the inner moving part near the light source. After one end of the light guide plate passes through the insertion interface, it is fixed in place by the clamping force of the clamping component. The clamping component generates pressure through elastic deformation or mechanical structure to clamp the light guide plate, ensuring that the light guide plate remains in a fixed position during operation and will not shift due to vibration or external forces.

[0015] Preferably, the clamping member has a clamping opening on one side, and inclined positioning plates are installed on the upper and lower sides inside the clamping member. A limiting protrusion is installed on the outer wall of one end of the light guide plate. The end of the light guide plate is inserted into the clamping opening and pressed and positioned by the positioning plate. The limiting protrusion is stuck on the outer side of the end of the positioning plate.

[0016] This design features a clamping opening on one side of the clamping component, with inclined positioning plates installed on the upper and lower sides inside. A limiting protrusion is provided on the outer wall of one end of the light guide plate. During installation, the end of the light guide plate is inserted into the clamping opening. The positioning plates use their inclined angle to generate a clamping force on the light guide plate, while the limiting protrusion is engaged with the outer side of the positioning plate end, forming a double limiting structure that fixes and positions the light guide plate from multiple directions.

[0017] Preferably, the end of the light guide plate away from the inner moving part is integrally formed with a curved end, which is bent toward the surface of the vehicle window glass.

[0018] This design features a curved end integrally formed at the end of the light guide plate furthest from the inner moving part, with the curved end bending towards the surface of the window glass. Based on the principles of light refraction and reflection, the curved structure can change the direction of light propagation, allowing the light to be projected more concentratedly onto the film-covered area along the edge of the window.

[0019] Preferably, the light guide plate is made of high-transparency acrylic sheet material.

[0020] This light guide plate is made of high-transparency acrylic sheet material. Acrylic sheet has excellent optical transparency, which can minimize light loss during transmission, while also possessing a certain degree of strength and durability. Utilizing its optical properties, it ensures that the light emitted by the light source is transmitted to the target area efficiently and stably.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This window tinting tool, featuring positioning and supplemental lighting functions, achieves several significant technical benefits through its unique structural design. Firstly, the outer and inner moving parts magnetically attach to each other across the window glass, enabling rapid and precise positioning and cutting of the window tinting film. Compared to traditional positioning methods relying on experience and simple measuring tools, and the single-function positioning devices described in the comparison document, this structure effectively avoids film misalignment, significantly improves the accuracy of film positioning, ensures the cut film adheres perfectly to the window glass, and substantially enhances the tinting effect and aesthetics.

[0023] In terms of supplemental lighting, the light source inside the inner moving part guides the light through a detachable light guide plate, accurately projecting light onto areas with poor visibility, such as the edges of the car window. The light guide plate is made of high-transparency acrylic material, and the end away from the inner moving part has a curved end that bends towards the surface of the car window glass. This design makes the light distribution more uniform and concentrated. Compared with the simple lighting methods or designs that only focus on other functions in existing film application tools, it provides the operator with a clearer field of vision, accurately positions the cutting position, and greatly improves the quality and efficiency of film application.

[0024] Furthermore, the anti-slip strips on the outer and inner moving parts enhance the stability of the tool when held by the operator. The light guide plate and the inner moving part are connected by a plug-in joint and fixed by clamps, facilitating the disassembly and installation of the light guide plate and enhancing the convenience and flexibility of the tool. In summary, this utility model integrates precise positioning and efficient supplementary lighting functions, effectively overcoming the shortcomings of existing technologies, and has outstanding practical value and broad application prospects in the field of car window tinting tools.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model provides a window tinting auxiliary tool with positioning and supplemental lighting functions, such as... Figure 1 , Figure 3 As shown, the device includes an outer movable component 1 and an inner movable component 2. The outer movable component 1 is located on the outer side of the window glass, and the inner movable component 2 is located on the inner side of the window glass. The outer movable component 1 and the inner movable component 2 are magnetically attracted to each other across the window glass. A light guide plate 3 is detachably installed on one side of the inner movable component 2. A light source 23 is installed inside the inner movable component 2 near the end of the light guide plate 3. The light from the light source 23 is guided by the light guide plate 3 to illuminate the edge of the window. A power supply battery is installed inside the inner movable component 2, and the light source 23 is powered by an external rechargeable battery for easy portability and use.

[0034] The outer movable component 1 is located on the outer side of the window glass, and the inner movable component 2 is located on the inner side of the window glass. They are magnetically attracted to each other, utilizing the penetrating and attractive properties of magnetism to achieve a tight fit through the window glass, forming a stable positioning structure. A light guide plate 3 is detachably installed on one side of the inner movable component 2. A light source 23 is installed inside the inner movable component 2 near the end of the light guide plate 3. Using the optical properties of the light guide plate 3, the light emitted by the light source 23 is precisely guided to the edge of the window. This achieves precise positioning during the window tinting process, avoiding inaccurate film cutting and subsequent film misalignment caused by insufficient manual operation experience or simple measuring tools. The light guide plate 3 illuminates the window edge, effectively solving the problem of difficulty in observing details during window tinting in low-light conditions, reducing bubbles and impurities, and improving tinting quality and efficiency.

[0035] In this embodiment, as Figure 2 , Figure 3As shown, the outer movable part 1 includes an outer shell 11, and an outer magnetic absorbing piece 12 is installed at the bottom of the outer shell 11. The inner movable part 2 includes an inner shell 21, and an inner magnetic absorbing piece 22 is installed at the top of the inner shell 21. The outer magnetic absorbing piece 12 and the inner magnetic absorbing piece 22 are attracted to each other by magnetic attraction.

[0036] The outer movable component 1 includes an outer shell 11, with an outer magnetic absorbing plate 12 mounted on the bottom of the outer shell 11; the inner movable component 2 includes an inner shell 21, with an inner magnetic absorbing plate 22 mounted on the top of the inner shell 21. The outer magnetic absorbing plate 12 and the inner magnetic absorbing plate 22 attract each other magnetically, allowing the outer movable component 1 and the inner movable component 2 to be firmly attached to both sides of the car window glass. The magnetic force is moderate, ensuring stable adsorption while facilitating position adjustment during operation. This further enhances the stability and reliability of the adsorption between the outer movable component 1 and the inner movable component 2, ensuring that the positioning structure will not easily loosen or shift during the film application process, providing a solid foundation for precise film application and improving the accuracy and stability of film application positioning.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, anti-slip strips are provided on the outer walls of both the outer moving part 1 and the inner moving part 2.

[0038] Anti-slip strips are provided on the outer walls of both the outer moving part 1 and the inner moving part 2. The texture of the anti-slip strips increases the friction between the tool and the operator's hand. According to the principle of friction, the rough surface effectively prevents the tool from slipping from the hand during use. This improves the stability of the tool when the operator holds it, allowing for more precise control during film application, especially when making fine adjustments and applying pressure. This reduces operational errors and improves the convenience and safety of film application.

[0039] Furthermore, such as Figure 3 As shown, an insertion interface 24 is provided on one side of the inner movable part 2, and one end of the light guide plate 3 is inserted into the insertion interface 24.

[0040] An insertion interface 24 is provided on one side of the inner movable component 2, and one end of the light guide plate 3 is inserted into the insertion interface 24. This structure is based on the principle of mechanical connection, and the installation and removal of the light guide plate 3 and the inner movable component 2 are achieved by insertion and removal. The shape of the insertion interface 24 and the end of the light guide plate 3 are adapted to ensure the tightness and stability of the connection. This facilitates the installation and removal of the light guide plate 3, and when the light guide plate 3 is damaged or needs cleaning or replacement, the operator can quickly complete the operation. At the same time, in different film application scenarios, the installation or removal of the light guide plate 3 can be flexibly selected according to actual needs, enhancing the flexibility and versatility of tool use.

[0041] Furthermore, such as Figure 4 , Figure 5As shown, a clamping member 32 is installed inside the inner movable part 2 near the light source 23, and one end of the light guide plate 3 passes through the insertion interface 24 and is clamped and fixed by the clamping member 32.

[0042] A clamping member 32 is installed inside the inner movable part 2 near the light source 23. After one end of the light guide plate 3 passes through the insertion interface 24, it is fixed by the clamping force of the clamping member 32. The clamping member 32 generates pressure through elastic deformation or mechanical structure to clamp the light guide plate 3, ensuring that the light guide plate 3 is fixed in position during operation and will not shift due to vibration or external force. This further improves the firmness of the installation of the light guide plate 3, prevents the light guide plate 3 from loosening or falling off during use, ensures the stability and accuracy of light transmission, and thus continuously provides stable lighting for the edge of the car window, ensuring the smooth progress of the film application work.

[0043] Furthermore, such as Figure 4 , Figure 5 The clamping member 32 shown has a clamping opening 321 on one side. Inclined positioning plates 322 are installed on the upper and lower sides inside the clamping member 32. A limiting protrusion 33 is installed on the outer wall of one end of the light guide plate 3. The end of the light guide plate 3 is inserted into the clamping opening 321 and pressed and positioned by the positioning plate 322. The limiting protrusion 33 is stuck on the outer side of the end of the positioning plate 322.

[0044] The clamping member 32 has a clamping opening 321 on one side, and inclined positioning plates 322 are installed on the upper and lower sides inside the clamping member 32. A limiting protrusion 33 is installed on the outer wall of one end of the light guide plate 3. During installation, the end of the light guide plate 3 is inserted into the clamping opening 321. The positioning plate 322 uses its inclined angle to generate a pressing force on the light guide plate 3. At the same time, the limiting protrusion 33 is locked on the outer side of the end of the positioning plate 322, forming a double limiting structure, which fixes and positions the light guide plate 3 from multiple directions. This achieves precise positioning and secure installation of the light guide plate 3, effectively preventing displacement of the light guide plate 3 in the horizontal direction and avoiding shaking or detachment in the vertical direction, ensuring that the light guide plate 3 is always in the optimal working position, and improving light transmission efficiency and lighting effect.

[0045] Furthermore, such as Figure 4 , Figure 5 As shown, the light guide plate 3 has a bent end 31 integrally formed at one end away from the inner moving part 2, and the bent end 31 is bent toward the surface of the car window glass.

[0046] The light guide plate 3 has an integrally formed curved end 31 at the end furthest from the inner moving part 2, and the curved end 31 bends towards the surface of the window glass. Based on the principles of light refraction and reflection, the structure of the curved end 31 changes the direction of light propagation, allowing the light to be projected more concentratedly onto the film-covered area along the edge of the window. This optimizes the projection angle and distribution of light, making the light more uniform and concentrated on the edge of the window, effectively improving the brightness and clarity of the area, providing operators with a better field of vision, further improving the film-covering quality, and reducing film-covering defects caused by poor lighting.

[0047] Furthermore, the light guide plate 3 is made of high-transparency acrylic sheet material.

[0048] The light guide plate 3 is made of high-transparency acrylic sheet material. Acrylic sheet has excellent optical transparency, which can minimize light loss during transmission, while also possessing a certain degree of strength and durability. Utilizing its optical properties, it ensures that the light emitted by the light source 23 is efficiently and stably transmitted to the target area. This ensures efficient light transmission, allowing the light emitted by the light source 23 to be projected onto the edge of the car window to the maximum extent, improving lighting brightness and effect. At the same time, the strength and durability of the high-transparency acrylic sheet material extend the service life of the light guide plate 3, reduce tool maintenance costs, and enhance the practicality and reliability of the auxiliary tool.

[0049] When using this utility model of a car window tinting auxiliary tool with positioning and supplemental lighting functions, the operator should first check the integrity of the outer moving part 1 and the inner moving part 2, ensuring that the outer magnetic absorbing sheet 12 and the inner magnetic absorbing sheet 22 are magnetically normal and that the light source 23 has sufficient power, which is supplied by the rechargeable battery inside the inner moving part 2. If supplemental lighting is needed, insert one end of the light guide plate 3 into the insertion interface 24 of the inner moving part 2. Through the cooperation of the clamping port 321 of the clamping part 32, the positioning plate 322 and the limiting protrusion 33, the light guide plate 3 is firmly installed, and at the same time, the bent end 31 is adjusted to face the car window glass surface.

[0050] The operator holds the outer movable part 1 in one hand and places it on the outside of the car window glass, while holding the inner movable part 2 in the other hand and placing it in the corresponding position on the inside of the car window glass. The magnetic attraction of the outer magnetic plate 12 and the inner magnetic plate 22 causes the two movable parts to adhere together through the car window glass, forming a stable positioning structure. At this time, the operator can fine-tune the position of the tools by holding the anti-slip strips on the outer walls of the outer movable part 1 and the inner movable part 2, according to the shape of the car window and the film application requirements, to achieve precise positioning.

[0051] After positioning is completed, if the ambient light is insufficient, the operator can turn on the light source 23 inside the inner moving part 2. The light emitted by the light source 23 enters the light guide plate 3. Utilizing the optical properties of the light guide plate 3, the light is conducted within the light guide plate 3 and its propagation direction is changed through the curved end 31, so that it is evenly and centrally projected onto the film-covered area along the edge of the car window, providing the operator with a clear field of vision.

[0052] Under precise positioning and good lighting conditions, the operator begins the window tinting operation. The film is laid on the window glass, and the positioning reference of the auxiliary tools is used to ensure accurate placement of the film. At the same time, with the help of the light guide plate 3, the operator carefully observes the edge of the window, cuts the film, and removes air bubbles and cleans impurities during the later application process to ensure that the film adheres tightly, is flat and wrinkle-free, until the entire tinting work is completed.

[0053] After the film application is completed, turn off the light source 23. If the light guide plate 3 is no longer needed, it can be pulled out from the insertion interface 24 of the inner moving part 2 and the auxiliary tools can be properly stored for future use.

[0054] Finally, it should be noted that the electronic components in the light source 23 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between the electrical components in the above working principle to complete the electrical connection. All of these are technologies known in the art.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
