Description

Technical Field

[0001] This utility model relates to the field of automotive window film cutting technology, and more specifically, to an automotive window film window opening and cutting device. Background Technology

[0002] In the process of car decoration, to ensure clear visibility for the driver and meet regulatory requirements, triangular window shapes are usually cut out of the window film. Currently, window film cutting mainly relies on manual operation, using simple tools such as rulers and knives for marking and cutting. This method has many drawbacks. First, manual cutting makes it difficult to guarantee the shape accuracy and dimensional consistency of the cut positions. Differences in the techniques of different operators can lead to inconsistent cutting results, affecting aesthetics and usability. Second, manual operation is slow, inefficient, and inconvenient. In addition, improper force control during manual cutting can easily cause scratches or damage to the window film, increasing material costs.

[0003] Existing window film cutting equipment is mainly designed for conventional cutting of window film in the length or width direction, and is not suitable for cutting triangular windows with a specific shape for the driver's side window film of automobiles. Therefore, this application proposes a device that can quickly and accurately cut triangular windows from the driver's side window film of automobiles. Utility Model Content (a) Content of the utility model

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a window film cutting device to solve the problems of low precision, low efficiency, and easy damage to the window film in the manual cutting of the triangular window film of the driver's side of a car, so as to achieve fast and accurate cutting of the triangular window that meets the requirements.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A window film cutting device for automobiles includes a support base plate, a telescopic positioning component, a cutting mechanism, and a locking adjustment component. The support base plate is a long strip structure with telescopic positioning components at both ends. The cutting mechanism is located on the upper side of the support base plate, and the locking adjustment component is located on the front side of the support base plate. The locking adjustment component is connected to the cutting mechanism.

[0009] The cutting mechanism includes a base, an inner groove, an adjusting bolt, a blade holder, and a cutting blade. The base is fitted onto the upper side of the support substrate. An inner groove is provided inside the base, and a blade holder is provided in the inner groove. A cutting blade is fixedly installed on the blade holder by a set screw. An adjusting bolt is threaded through the left end of the base, and the right end of the adjusting bolt is rotatably connected to the blade holder.

[0010] Furthermore, a T-shaped sliding plate is fixedly provided on the rear side of the tool holder, and a T-shaped sliding groove adapted to the T-shaped sliding plate is provided on the rear side of the inner groove. The T-shaped sliding plate is inserted into the T-shaped sliding groove and slidably connected with it.

[0011] Furthermore, the locking adjustment assembly includes a positioning base plate, a movable groove, a locking knob, a screw, and a connecting plate. The connecting plate is fixed to the bottom of the base near the left end face. The positioning base plate is fixed to the bottom of the support base plate. The positioning base plate has a movable groove inside. A screw is inserted into the movable groove. A baffle with a diameter larger than the width of the movable groove is fixed to the right end of the screw. The left end of the screw passes through the connecting plate and extends out of it. A locking knob is screwed onto the screw on the outside of the connecting plate.

[0012] Furthermore, a guide slider A is fixedly provided at the bottom of the base, and a guide groove A adapted to the guide slider A is provided on the upper surface of the support base plate. The guide slider A is inserted into the guide groove A and slidably connected thereto. A guide slider B is fixedly provided at the bottom of the connecting plate, and a guide groove B adapted to the guide slider B is provided on the front side of the support base plate. The guide slider B is inserted into the guide groove B and slidably connected thereto.

[0013] Furthermore, a lever is fixed on the outer surface of the connecting plate.

[0014] Furthermore, the telescopic positioning assembly includes an adjusting nut, an extension rod, a top plate, and a threaded groove. The extension rod is inserted into the outer end of the support base plate and is telescopically connected to it. The top plate is fixed to the outer end of the extension rod. A rotatable adjusting nut is embedded on the front side of the support base plate at a position corresponding to the extension rod. A threaded groove adapted to the adjusting nut is formed on the contact surface of the extension rod and the adjusting nut. The adjusting nut is engaged with the threaded groove.

[0015] Furthermore, a cushioning pad is affixed to the outer surface of the top plate.

[0016] (III) Working Principle

[0017] In actual use, first place the device on the lower edge of the window inside the car door. Then, use the telescopic positioning components at both ends to adjust the overall length of the device. By rotating the adjusting nut on the support base plate, it engages with the threaded groove of the extension rod, driving the extension rod to extend and retract. This allows the top plate to press against both sides of the window. At the same time, the device is stably fixed in the window position to be cut by the support of the top plates on both sides, ensuring that the device does not shake during the cutting process.

[0018] Then, release the locking knob of the locking adjustment assembly to allow the screw to move within the movable groove of the positioning base plate. At this time, the base can slide along the guide groove A of the support base plate via the bottom guide slider A, while the guide slider B at the bottom of the connecting plate slides synchronously along the guide groove B, achieving smooth movement of the entire cutting mechanism along the length of the support base plate. The operator can push the connecting plate with a lever to quickly move the base to the position where cutting is required.

[0019] Next, rotate the adjusting bolt on the left end of the base. Its right end is rotatably connected to the blade holder, pushing the blade holder to move in the inner groove. The T-shaped sliding plate on the rear side of the blade holder slides along the T-shaped groove of the inner groove, restricting the blade holder to move only in a straight line to avoid deviation, thereby precisely adjusting the lateral position of the cutting blade (perpendicular to the length direction of the support substrate), realizing the adjustment of the cutting depth of the cutting blade to adapt to the thickness of the window film;

[0020] After the position adjustment is completed, tighten the locking knob of the locking adjustment component to press it against the connecting plate. The base position is fixed by the cooperation of the screw and the baffle to prevent the cutting mechanism from shifting during cutting. Then, control the window to rise, so that the window moves relative to the cutting blade, and then the cutting blade fixed on the blade holder can be used to cut the window film.

[0021] (iv) Beneficial effects

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This utility model, through its supporting base plate, telescopic positioning component, cutting mechanism, and locking adjustment component, enables rapid cutting of car window film, improves operational convenience, reduces human error, and ensures cutting accuracy through guiding, positioning, and locking design, preventing damage to the car window film due to improper operation and improving cutting efficiency.

[0024] 2. This utility model can quickly cut car window film through the set cutting mechanism. At the same time, the cutting mechanism can move horizontally on the support base plate, and can accurately position the cutting blade to the appropriate position according to the cutting requirements of different car window films, which greatly improves the cutting accuracy and solves the problem of low precision of manual cutting.

[0025] 3. The telescopic positioning assembly connects to the threaded groove on the extension rod via an adjusting nut, allowing for quick adjustment of the extension rod's telescopic length. This enables the top plate to be rapidly positioned against both sides of the vehicle window, achieving rapid fixation of the device. Compared to manual positioning and fixing, this significantly saves time and improves pre-cutting preparation efficiency.

[0026] 4. The locking knob in the locking adjustment assembly works with the screw to fix the position of the base after the cutting blade position is adjusted, preventing the base from moving during the cutting process and ensuring the stability of the cutting mechanism during the cutting process, thereby ensuring the accuracy and consistency of the cutting.

[0027] 5. The cushioning pads affixed to the outer side of the roof panel act as a buffer when the roof panel comes into contact with the window, preventing damage to the window components due to direct pressure from the roof panel and protecting the surface quality of the window components.

Detailed Implementation

[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0035] Example:

[0036] like Figures 1 to 5As shown, a window film cutting device includes a support base plate 1, a telescopic positioning component 2, a cutting mechanism 3, and a locking adjustment component 4. The support base plate 1 is a long strip structure, which serves as the basic support structure of the entire device and provides installation positions and support platforms for other components. Telescopic positioning components 2 are provided at both ends of the support base plate 1. The cutting mechanism 3 is provided on the upper side of the support base plate 1, and the locking adjustment component 4 is provided on the front side of the support base plate 1. The locking adjustment component 4 is connected to the cutting mechanism 3.

[0037] The cutting mechanism 3 includes a base 31, an inner groove 32, an adjusting bolt 33, a blade holder 34, and a cutting blade 36. The base 31 is fitted onto the upper side of the support base plate 1, providing mounting positions for components such as the blade holder 34 and the adjusting bolt 33, and is connected to the support base plate 1 to enable the cutting mechanism 3 to move on the support base plate 1. The base 31 has an inner groove 32 inside to accommodate the blade holder 34 and provide mounting space for it. The blade holder 34 is installed in the inner groove 32 for mounting the cutting blade 36, and through its connection with the adjusting bolt 33, the cutting blade 36 moves within the inner groove 32 under the action of the adjusting bolt 33. The cutting blade 36 is fixedly mounted on the blade holder 34 by a set screw 37 and is used to cut the window film. An adjusting bolt 33 is threaded through the left end of the base 31 to precisely adjust the position of the cutting blade 36. The right end of the adjusting bolt 33 is rotatably connected to the blade holder 34. By rotating the adjusting bolt 33, the blade holder 34 is pushed to move in the inner groove 32, thereby adjusting the position of the cutting blade 36. This design solves the problems of low precision, low efficiency and easy damage to the window film in the existing technology of manually cutting the triangular window film of the driver's side of a car.

[0038] In this embodiment, a T-shaped sliding plate 38 is fixedly provided on the rear side of the blade holder 34, and a T-shaped groove 39 adapted to the T-shaped sliding plate 38 is provided on the rear side of the inner groove 32. The T-shaped sliding plate 38 is inserted into the T-shaped groove 39 and slidably connected to it. The T-shaped sliding plate 38 and the T-shaped groove 39 realize the sliding connection between the blade holder 34 and the inner groove 32, restrict the movement direction of the blade holder 34, so that it can only move along the direction of the T-shaped groove 39, thereby ensuring the stability of the cutting blade 36 during the movement, preventing the cutting blade 36 from deviating, thereby ensuring the cutting accuracy of the cutting blade 36 and ensuring the cutting quality.

[0039] In this embodiment, the locking adjustment assembly 4 includes a positioning base plate 41, a movable groove 42, a locking knob 44, a screw 45, and a connecting plate 46. The connecting plate 46 is fixed to the bottom of the base 31 near the left end face, and the positioning base plate 41 is fixed to the bottom of the support base plate 1. The positioning base plate 41 has a movable groove 42 inside, and a screw 45 is inserted into the movable groove 42. A baffle 48 with a diameter larger than the width of the movable groove 42 is fixed to the right end of the screw 45. The left end of the screw 45 passes through the connecting plate 46 and extends out of it. A locking knob 44 is screwed onto the screw 45 on the outside of the connecting plate 46. The locking adjustment assembly 4 can lock and unlock the position of the base 31. After adjusting the position of the cutting blade 36, the base 31 is fixed by the locking knob 44 to ensure the stability of the cutting mechanism 3 during the cutting process and improve the cutting accuracy.

[0040] In this embodiment, a guide slider A35 is fixedly mounted on the bottom of the base 31, and a guide groove A11 adapted to the guide slider A35 is formed on the upper surface of the support base plate 1. The guide slider A35 is engaged in the guide groove A11 and slidably connected thereto. A guide slider B47 is fixedly mounted on the bottom of the connecting plate 46, and a guide groove B12 adapted to the guide slider B47 is formed on the front side of the support base plate 1. The guide slider B47 is engaged in the guide groove B12 and slidably connected thereto. The guide slider A35 at the bottom of the base 31 engages in the guide groove A11 on the upper surface of the support base plate 1, realizing the sliding connection between the base 31 and the support base plate 1, restricting the movement direction of the base 31, so that it can only move along the direction of the guide groove A11. This ensures the stability of the base 31 during movement, prevents the base 31 from deviating, thereby improving the movement accuracy of the cutting mechanism 3 and ensuring the cutting quality. Meanwhile, the movement direction of the connecting plate 46 is further restricted by the guide slider B47 and the guide groove B12, which enhances the stability of the base 31 movement. Together with the guide slider A35 and the guide groove A11, they ensure the stability and accuracy of the base 31 during movement and improve the cutting accuracy of the entire device.

[0041] In this embodiment, a lever 43 is fixed on the outer side of the connecting plate 46, which makes it convenient for the operator to manually move the connecting plate 46, thereby driving the base 31 to move and adjusting the position of the cutting blade 36. This improves the convenience of operation and allows the operator to adjust the position of the cutting mechanism 3 more easily and accurately.

[0042] In this embodiment, the telescopic positioning assembly 2 includes an adjusting nut 21, an extension rod 22, a top plate 23, and a threaded groove 24. The extension rod 22 is inserted into the outer end of the support base plate 1 and is telescopically connected to it. The top plate 23 is fixed to the outer end of the extension rod 22. A rotatable adjusting nut 21 is embedded on the front side of the support base plate 1 at a position corresponding to the extension rod 22. A threaded groove 24 adapted to the extension rod 22 is formed on the contact surface with the adjusting nut 21, and the adjusting nut 21 is engaged with the threaded groove 24. The telescopic positioning assembly 2 allows adjustment of the overall length of the device to accommodate windows of different widths. In actual use, the extension rods 22 on both sides can drive the top plate 23 to press against the sides of the window, thus fixing the device in place.

[0043] In this embodiment, a buffer pad 25 is attached to the outer side of the roof panel 23, which can buffer and protect the contact points between the roof panel 23 and the window, and prevent the window from being worn due to direct pressure from the roof panel 23.

[0044] The working principle of this type of car window film cutting and opening device:

[0045] In actual use, the device is first placed on the lower edge of the window on the inside of the car door. Then, the overall length of the device is adjusted using the telescopic positioning components 2 at both ends. By rotating the adjusting nut 21 on the support base plate 1, it engages with the threaded groove 24 of the extension rod 22, causing the extension rod 22 to extend and retract, thereby pressing the top plate 23 against both sides of the window. The buffer pad 25 on the outside of the top plate 23 prevents the window from being squeezed and abraded. At the same time, the device is stably fixed at the position of the window to be cut by the support of the top plates 23 on both sides, ensuring that the device does not shake during the cutting process.

[0046] Then, release the locking knob 44 of the locking adjustment assembly 4, allowing the screw 45 to move within the movable groove 42 of the positioning base plate 41. At this time, the base 31 can slide along the guide groove A of the support base plate 1 via the guide slider A at the bottom, while the guide slider B at the bottom of the connecting plate 46 slides synchronously along the guide groove B, achieving smooth movement of the entire cutting mechanism 3 along the length of the support base plate 1. The operator can push the connecting plate 46 via the lever 43 to quickly move the base 31 to the position where cutting is required.

[0047] Next, the adjusting bolt 33 on the left end of the rotating base 31 is rotatably connected to the blade holder 34 on its right end, pushing the blade holder 34 to move in the inner groove 32. The T-shaped sliding plate on the rear side of the blade holder 34 slides along the T-shaped groove of the inner groove 32, restricting the blade holder 34 to move only in a straight line to avoid deviation, thereby precisely adjusting the lateral position of the cutting blade 36 perpendicular to the length direction of the support base plate 1, realizing the adjustment of the cutting depth of the cutting blade 36, so that it can adapt to the thickness of the window film;

[0048] After the position adjustment is completed, tighten the locking knob 44 of the locking adjustment component 4 to press it against the connecting plate 46. The position of the base 31 is fixed by the cooperation of the screw 45 and the baffle 48 to prevent the cutting mechanism 3 from shifting during cutting. Then control the window to rise, so that the window moves relative to the cutting blade 36, and then use the cutting blade 36 fixed on the blade holder 34 to cut the window film.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
