Description

Technical Field

[0001] This utility model relates to the field of film application technology, specifically to a film application device and film application assembly. Background Technology

[0002] With the widespread use of smartphones, tablets, and other electronic devices, screen protectors have become an essential accessory for protecting device screens from scratches and damage. To facilitate self-application, various screen protector application aids have emerged on the market. Currently, common application aids typically consist of a base and a top cover. The top cover is movably connected to the base, which has a recess for holding the electronic device. The top cover is in a closed state relative to the base. When closed, the top cover completely covers the recess, resulting in a large and heavy device that is inconvenient to carry and store. Furthermore, because the top cover completely covers the recess, users cannot observe the adhesion between the screen protector and the screen in real time during the application process, making it impossible to promptly detect issues such as bubbles, dust, or misalignment.

[0012] In one alternative embodiment, the pressing part is recessed into a pressing groove on one side of the top surface of the base, or the pressing part is provided with a plurality of protruding ribs on one side of the top surface of the base.

[0013] In one alternative embodiment, the top cover has a flexible pressure-film member on the side facing the base, and when the top cover is in a closed state, the flexible pressure-film member is partially placed in the receiving groove.

[0014] In one alternative embodiment, the top cover is hinged to the first end, and the base is provided with two first sidewalls located on opposite sides of the receiving groove, the direction from one first sidewall to the other first sidewall being perpendicular to the direction from the first end to the tail end; The upper cover includes a cover plate and two second sidewalls connected to opposite sides of the cover plate; The first sidewall is provided with an elastic locking member. When the top cover is in the closed state, the second sidewall is engaged with the first sidewall through the elastic locking member.

[0015] In one alternative embodiment, the outer surface of the first sidewall away from the receiving groove is recessed in the direction of the receiving groove to form a first clearance groove; The first end of the elastic locking member is connected to the side wall of the first clearance groove, and the second end is suspended in the first clearance groove. The elastic locking member includes a pressing section and a snap-fit ​​section from the first end to the second end. When the top cover is in the closed state, the pressing section is exposed on the second side wall, and the snap-fit ​​section snaps into the second side wall.

[0016] In one alternative embodiment, the snap-fit ​​segment has a first snap-fit ​​portion on the side away from the receiving groove; each of the two second sidewalls has a snap-fit ​​groove on the opposite side, and the end of the second sidewall away from the cover plate is bent to form a second snap-fit ​​portion, the second snap-fit ​​portion constituting part of the sidewall of the snap-fit ​​groove. When the top cover is in the closed state, the first engaging portion is at least partially placed in the engaging groove, and the second engaging portion is placed on the side of the first engaging portion away from the opening of the receiving groove, so as to fix the first engaging portion in the engaging groove.

[0017] In one alternative embodiment, the first engaging portion is provided with a first guide surface on the side away from the receiving groove, and the first guide surface gradually slopes away from the groove opening near the receiving groove and away from the groove opening away from the receiving groove.

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention. Example 1

[0027] Please see Figure 1-5 As shown, Figure 1A perspective view of an embodiment of the film-applying device 100 of this utility model is shown. The film-applying device 100 includes a base 2 and a top cover 1. The base 2 includes a front end 21 and a rear end 22. The top surface of the base 2 is recessed with a receiving groove 3 for accommodating an electronic device 300, and the receiving groove 3 is located between the front end 21 and the rear end 22. The top cover 1 is movably connected to the front end 21, so that the top cover 1 can be flipped relative to the base 2.

[0028] Specifically, electronic device 300 refers to devices that require screen protector application, such as smartphones or tablets, which are electronic products with display screens. Figure 2 As shown, the electronic device 300 is fixed by setting a receiving groove 3 in the base 2 to prevent the electronic device 300 from shifting during the film application process.

[0029] like Figure 5 As shown, the upper cover 1 and the base 2 are movably connected at their first ends 21, allowing the upper cover 1 to move relative to the base 2. When the upper cover 1 moves above the receiving groove 3, the upper cover 1 is in a closed state. When the upper cover is in the closed state, the portion of the receiving groove away from the tail end is covered by the upper cover, while the portion near the tail end is exposed. Along the length direction from the first end 21 to the tail end 22, the length of the upper cover 1 is less than the length of the receiving groove 3. Figure 2 As shown, when the upper cover 1 is away from the opening of the receiving groove 3, the upper cover 1 is in the open state. Figure 3 and Figure 4 As shown, when the top cover 1 is in the open state, the electronic device 300 is first placed into the receiving slot 3, so that the screen of the electronic device 300 is vertically upward. Then, the protective film assembly 200 is placed in the preset position of the base 2. Finally, the top cover 1 is rotated to the closed state. When the top cover 1 is in the closed state, part of the top cover 1 is placed in the receiving cavity to squeeze the protective film assembly 200, so that the protective film assembly 200 moves towards the screen of the electronic device 300 in the receiving slot 3 and finally connects with the screen of the electronic device 300.

[0030] like Figure 5As shown, along the length from the first end 21 to the last end 22, the length of the upper cover 1 covering the receiving groove 3 is less than the length of the receiving groove 3. When the upper cover 1 is in the closed state, the portion of the opening of the receiving groove 3 near the first end 21 is covered by the upper cover 1, while the portion away from the first end 21 is exposed to the environment. This means that when applying a film to the electronic device 300 using the film application device 100, the main film 201 of the protective film assembly 200 near the first end 21 will first connect to the screen of the electronic device 300 under the action of the upper cover 1, while the main film 201 away from the first end 21 will gradually connect to the screen of the electronic device 300. This means that one end of the main film 201 will first connect to the screen of the electronic device 300, and then gradually approach and connect to the screen of the electronic device 300 at the other end along the length direction. During the bonding process between the main film 201 and the screen of the electronic device 300, the air between the screen of the electronic device 300 and the main film 201 will be gradually expelled, preventing air bubbles from existing between the screen of the electronic device 300 and the main film 201 after bonding, thus improving the film application effect.

[0031] The length of the top cover 1 is less than the length of the receiving groove 3, which directly reduces the overall weight and volume of the film application device 100, making the film application device 100 easier to carry and store.

[0032] When the top cover 1 is in the closed state, such as Figure 5 As shown, part of the receiving groove 3 is covered by the upper cover 1, while the other part is exposed to the outside, forming an observation window 5, which makes the bonding process between the electronic device 300 and the main film 201 visible. Through the observation window 5, the user can observe in real time whether the bonding effect between the main film 201 and the electronic device 300 meets the requirements, such as whether there are air bubbles between the main film 201 and the screen, and whether the main film 201 and the screen of the electronic device 300 are aligned, so as to make timely adjustments and ensure the bonding effect.

[0033] In one optional embodiment, the width direction is perpendicular to the direction from the first end 21 to the last end 22, and the width of the upper cover 1 is smaller than the width of the receiving groove 3. Two third sidewalls (not shown in the figure) are symmetrically provided on opposite sides of the upper cover 1 along the width direction, and the two third sidewalls are located away from the end where the upper cover 1 and the base 2 are rotatably connected. When the upper cover 1 is in the closed state, the two third sidewalls are partially placed in the receiving groove 3 to compress the protective film assembly 200, causing the protective film assembly 200 to move into the receiving groove 3.

[0034] When the top cover 1 is closed, the two third sidewalls, located away from the lower edge of the top cover 1, are partially inserted into the receiving groove 3, contacting the upper surface of the protective film assembly 200 and applying pressure. This causes the main film 201 to move smoothly towards the bottom of the receiving groove 3 and adhere to the screen of the electronic device 300. In this embodiment, by symmetrically arranging the third sidewalls in the width direction, balanced lateral pressure is provided to both sides of the protective film assembly 200 in the width direction, ensuring the adhesion effect between the main film 201 and the screen.

[0035] In another implementation, such as Figure 2 As shown, a flexible pressing member 11 is provided on the side of the upper cover 1 facing the base. When the upper cover 1 is in the closed state, the flexible pressing member 11 is located between the upper cover 1 and the receiving groove 3, and part of the flexible pressing member 11 is placed in the receiving groove 3 and abuts against the protective film assembly 200.

[0036] Specifically, the flexible film-pressing component 11 is disposed on the inner surface of the upper cover 1, that is, on the side facing the receiving groove 3 when the upper cover 1 is in the closed state. When the upper cover 1 is flipped relative to the base 2 and in the closed state, the flexible film-pressing component 11 is located between the upper cover 1 and the receiving groove 3, and the flexible film-pressing component 11 is partially inserted into the receiving groove 3. The lower part of the flexible film-pressing component 11 away from the upper cover 1 directly abuts against the upper surface of the protective film assembly 200 placed on the screen of the electronic device 300, and applies pressure to the protective film assembly 200, causing the main film 201 near the first end 21 to move towards the screen and fit tightly against the screen.

[0037] The flexible pressing element 11 is preferably made of a material with excellent elasticity, such as silicone, foam, or rubber, to avoid the risk of scratches to the protective film assembly or screen surface that may be caused by hard materials. The width direction of the receiving groove 3 is perpendicular to the length direction of the receiving groove 3. In the width direction of the receiving groove 3, the size of the flexible pressing element 11 is slightly smaller than the width of the receiving groove 3, so that the lower part of the flexible pressing element 11 away from the top cover 1 has a larger contact area with the protective film assembly 200. While being able to be partially placed in the receiving groove 3, it ensures a large contact surface with the protective film assembly 200, so that the pressure generated when the top cover 1 is closed can be more evenly distributed on the protective film assembly 200. This further effectively guides the main film 201 near the first end 21 to move smoothly into the receiving groove 3, eliminating the air between the main film 201 and the screen of the electronic device 300, thereby significantly reducing the generation of air bubbles and ensuring that the main film 201 and the screen achieve a full and flat fit.

[0038] Furthermore, along its length, the length of the top cover 1 is less than or equal to half the length of the receiving groove 3, ensuring that more than half of the receiving groove 3 is continuously exposed to the external environment, forming a wide observation window 5, providing the user with an unobstructed view. This embodiment ensures the film application effect by limiting the length of the top cover 1 to less than or equal to half the length of the receiving groove 3, while directly reducing the material usage of the top cover 1, effectively reducing the overall weight and volume of the film application device 100, greatly improving its portability. The wide observation window 5 allows the user to more clearly monitor the adhesion between the main film 201 and the screen of the electronic device 300 during the pressing process, such as the direction of air bubbles, dust intrusion, or whether the position is aligned, thus enabling timely intervention and adjustment. The top cover 1 only covers the portion of the receiving groove 3 near the head end 21. When fine adjustments are needed, the user can directly operate and adjust the protective film assembly 200 in the exposed area without fully opening the top cover 1, simplifying the process and improving the efficiency and success rate of film application. Furthermore, along the length direction, the length of the upper cover covering the receiving groove 3 is less than or equal to one-third of the length of the receiving groove 3, thereby further ensuring the film application effect while reducing the amount of material used in the upper cover 1, effectively reducing the overall weight and volume of the film application device 100, so that the overall length of the film application device 100 is shorter when the upper cover is in the open state.

[0039] Furthermore, when the top cover 1 is in the closed state, at least the portion of the top cover 1 corresponding to the receiving groove 3 is made of transparent material. This transparent material can be polycarbonate (PC) or polymethyl methacrylate (PMMA), which possess high light transmittance, high strength, and abrasion resistance. The transparent top cover 1 greatly enhances the visualization of the screen protector application process. When applying the screen protector, the user's line of sight can penetrate the top cover 1 without obstruction, allowing direct and clear observation of the interior of the receiving groove 3. This enables the user to monitor the entire process of the protective film assembly 200 adhering to the screen of the electronic device 300 in real time, further improving the success rate and final effect of the application.

[0040] Furthermore, such as Figure 2 and Figure 3 As shown, the base 2 is provided with a plurality of positioning parts 24 for connecting with the protective film assembly 200 along the periphery of the receiving groove 3, and the positioning parts 24 are spaced apart from each other. At least some of the positioning parts 24 are located at the first end 21. When the upper cover 1 is in the closed state, the upper cover 1 covers the positioning parts 24 located at the first end 21.

[0041] The multiple positioning parts 24 spaced apart effectively restrict the movement and rotation of the protective film assembly 200 on the horizontal plane, ensuring precise positioning of the protective film assembly 200 and the screen of the electronic device 300, and effectively preventing misalignment during subsequent film application. Simultaneously, some positioning parts 24 are located at the first end 21. When the upper cover 1 is closed, the positioning parts 24 located at the first end 21 are covered by the upper cover 1, preventing accidental contact or interference with the positioned protective film assembly 200 by the user's hands or tools during the pressing process. If misalignment occurs during film application, the protective film assembly 200 can be adjusted.

[0042] Furthermore, such as Figure 2 and Figure 4 As shown, the side wall of the receiving groove 3 has at least one notch 25, which extends through the inner and outer sides and the top side of the side wall, and is located at the tail end. The notch 25 partially interrupts the side wall of the receiving groove 3 at a specific location, forming an open access channel, providing the user with direct operating space and a point of force to remove the electronic device 300 from the receiving groove 3. Along the thickness direction of the base 2 (i.e., the direction perpendicular to the upper surface of the base 2), the notch 25 extends downward from the top surface of the base 2 and through to the bottom wall of the receiving groove 3, so that the electronic device 300 placed in the receiving groove 3 is exposed to the outside from the back away from the screen to the screen through the notch 25. When the user needs to remove the electronic device 300 from the receiving groove 3, there is no need to pry it; force can be applied easily and safely through the notch 25, which greatly improves the convenience and efficiency of the removal and placement operation, and effectively avoids scratches or damage to the electronic device 300 or the receiving groove 3 during the removal and placement process.

[0043] In another implementation, such as Figure 4 and Figure 7 As shown, the bottom wall of the receiving groove 3 is provided with at least one through hole 26. When it is necessary to remove the electronic device 300 from the receiving groove 3, the user can insert his finger into the through hole 26 from the lower surface of the base 2 and directly press against the back of the electronic device 300 to apply an upward pushing force to the electronic device 300. This will easily push the electronic device 300 out of the groove smoothly and complete the pick-up and drop operation, avoiding scratches or squeezing of the side or screen edge of the electronic device 300 that may be caused by fingers or tools during the removal of the electronic device 300.

[0044] Furthermore, such as Figure 2 and Figure 6As shown, the base 2 has a pressing part 27 at its first end 21, which protrudes away from the tail end 22. When the top cover 1 is closed, the pressing part 27 protrudes from the top surface of the base 2. When the top cover 1 is flipped relative to the base 2 and is in a closed state, along the length from the first end 21 to the tail end 22, the top cover 1 is located between the pressing part 27 and the base 2, that is, the pressing part 27 protrudes from the upper surface of the base 2 and is not covered by the top cover 1.

[0045] The protective film assembly 200 includes a main film 201 and a first separation film 202 and a second separation film 203 respectively disposed on the upper and lower sides of the main film 201. The size of the first separation film 202 is larger than the size of the receiving groove 3. The second separation film 203 is provided with a tearing member 204 for removing the second separation film 203 from the main film 201.

[0046] like Figure 3 As shown, when the protective film assembly 200 is placed on the base 2, the second separation film 203 near the screen needs to be pulled off the main film 201 by the tearing member 204. At this time, the pressing part 27 provides the user with a key point of force. The user can place the thumb or index finger on the protruding pressing part 27 and apply downward pressure, which can effectively resist the pulling force when pulling the tearing member 204 and ensure that the film application device 100 remains stable.

[0047] like Figure 3 and Figure 4 As shown, the positioning part 24 is a cylindrical structure, and a corresponding positioning hole 205 is provided on the first separation membrane 202. When the protective film assembly 200 is placed on the base 2, the positioning part 24 passes through the positioning hole 205 to fix the protective film assembly 200 on the base 2.

[0048] like Figure 6 and Figure 7 As shown, a first clearance notch 12 is provided on one side where the upper cover 1 and the head end 21 are movably connected. The upper cover 1 is in an open state relative to the base 2. When the upper cover 1 is in the open state, as shown... Figure 2 As shown, the protruding end of the pressing part 27 is placed inside the first clearance notch 12; when the upper cover 1 is in the closed state, as... Figure 5 As shown, the pressing part 27 is exposed on the top surface of the base 2 through the first clearance notch 12 on one side of the top surface.

[0049] To achieve a tight fit between the pressing part 27 and the upper cover 1 and ensure functional integrity, a first clearance notch 12 is provided on the side of the upper cover 1 that is movably connected to the first end 21 of the base 2. When the upper cover 1 is fully open, the pressing part 27 located at the first end 21 is precisely accommodated within the space formed by the first clearance notch 12 on the upper cover 1, achieving a tight fit between the pressing part 27 and the upper cover 1. In the closed state, the pressing part 27 is exposed through the first clearance notch 12, ensuring that the user can access and apply force to the pressing part 27 without obstruction during the film application operation to stabilize the film application device 100. At the same time, by providing the first clearance notch 12 on the upper cover 1 and cooperating with the pressing part 27, structural interference is avoided, ensuring the functional integrity of the upper cover 1's relative movement to the base 2. This allows the upper cover 1 to open and close at a greater angle or be completely flat relative to the base 2, reducing the space occupied by the film application device 100 when stored.

[0050] like Figure 2 As shown, the pressing part 27 has a pressing groove 271 recessed on one side of the top surface of the base 2, or the pressing part 27 has multiple protruding ribs on one side of the top surface of the base 2 (not shown in the figure).

[0051] When the pressing part 27 has a pressing groove 271 recessed on one side of the top surface of the base 2, the user's fingertips can naturally embed and abut against the pressing groove 271 to apply pressure to the base 2, preventing the film application device 100 from moving. The design of the pressing groove 271 significantly increases the contact area between the finger and the pressing part 27, making the pressure distribution more uniform and the operation more comfortable and stable. At the same time, the groove structure of the pressing groove 271 can limit the finger and effectively prevent the finger from slipping when applying force.

[0052] The shape of the pressing groove 271 can be adapted to the curvature of the user's fingertip, for example, it can be set as an arc-shaped groove.

[0053] The pressing part 27 has multiple protruding ridges on one side of the top surface of the base 2. The ridges can be arranged parallel to each other, and the cross-sectional shape of the ridges can be arc-shaped or serrated. When the user's finger presses on the pressing part 27, the multiple protruding ridges can increase the friction between the pressing part 27 and the skin of the finger, greatly enhancing the anti-slip effect during pressing. Even in environments where the user's fingers are sweaty or wet, it can ensure stable pressing operation and prevent accidental slippage.

[0054] In one implementation of this embodiment, such as Figure 2As shown, the upper cover is hinged to the first end, and the base 2 has two first sidewalls 28 located on opposite sides of the receiving groove 3. The direction from one first sidewall 28 to the other first sidewall 28 is perpendicular to the direction from the first end 21 to the tail end 22. The upper cover 1 includes a cover plate 13 and two second sidewalls 14 connected to opposite sides of the cover plate 13. The first sidewall 28 is provided with an elastic locking member 4. When the upper cover 1 is in the closed state, such as Figure 5 As shown, the second sidewall 14 is engaged with the first sidewall 28 by the elastic locking member 4.

[0055] Two first sidewalls 28 are spaced apart along the width direction of the receiving groove 3, and two second sidewalls 14 are disposed on both sides of the upper cover 1 along the width direction of the receiving groove 3. The width direction of the receiving groove 3 is perpendicular to the length direction from the first end 21 to the last end 22. When the upper cover 1 moves, the second sidewall 14 will be squeezed against the elastic locking member 4 disposed on the first sidewall 28, causing the elastic locking member 4 to elastically deform. When the upper cover 1 is fully closed, the elastic locking member will restore its deformation and quickly lock into the second sidewall 14, thus connecting the first sidewall 28 and the second sidewall 14. In this embodiment, the first sidewall 28 and the second sidewall 14 are connected by the elastic locking member 4, which can effectively prevent the upper cover 1 from being accidentally opened due to shaking or slight collision of the film application device 100, thereby protecting the safety of the electronic device 300 and the protective film assembly 200 in the receiving groove 3.

[0056] The flexible pressing component is disposed between the two second side walls 14, and the upper part of the flexible pressing component is connected to the cover plate 13 near the cover plate 13. When the upper cover 1 is in the closed state, the flexible pressing component is placed in the receiving groove 3 under the rotation of the upper cover 1 to achieve compression and bonding with the protective film assembly 200.

[0057] Furthermore, such as Figure 10 and Figure 11 As shown, the outer surface of the first sidewall 28 away from the receiving groove 3 is recessed in the direction of the receiving groove 3 to form a first clearance groove 281; the first end 41 of the elastic locking member 4 is connected to the sidewall of the first clearance groove 281, and the second end 42 is suspended in the first clearance groove 281. The elastic locking member 4 includes a pressing section 43 and a snap-fit ​​section 44 from the first end 41 to the second end 42. When the upper cover 1 is in the closed state, the pressing section 43 is exposed on the second sidewall 14, and the snap-fit ​​section 44 snaps into the second sidewall 14.

[0058] Specifically, the outer surface of the first sidewall 28 away from the receiving groove 3 is recessed towards the receiving groove 3 to form a first clearance groove 281. The first end 41 of the elastic locking member 4 is connected to the sidewall of the first clearance groove 281, and the second end 42 is suspended in the first clearance groove 281. The elastic locking member 4 includes a pressing section 43 and a locking section 44 from the first end 41 to the second end 42. The locking section 44 is suspended in the first clearance groove 281. When the locking section 44 is squeezed towards the receiving cavity, the elastic locking member 4 will deform, causing the locking section 44 to shift into the first clearance groove 281.

[0059] The distance between the two second sidewalls 14 is greater than the width of the base 2, so that when the top cover 1 is in the closed state, the two first sidewalls 28 are partially placed between the two second sidewalls 14. During the rotation of the second sidewalls 14 toward the first sidewalls 28, they will press the elastic locking member 4 located on the outer surface of the receiving groove 3, causing the snap-fit ​​section 44 of the elastic locking member 4 to shift into the first clearance groove 281. When the top cover 1 is rotated to the closed state, the snap-fit ​​section 44 restores its deformation and snaps into the second sidewall 14, fixing the top cover 1 in the closed position.

[0060] When the top cover 1 is closed, the pressing section 43 of the elastic locking member 4 protrudes from the edge of the second side wall 14 near the tail end 22 into the external environment, allowing the user to easily access the pressing section 43. When the user needs to open the top cover 1, the user directly applies pressure to the pressing part 27, causing the elastic locking member 4 to shift into the first relief groove 281, releasing the engagement between the second side wall 14 and the locking section 44, and releasing the closed state of the top cover 1.

[0061] In this embodiment, when the pressing section 43 is subjected to inward pressure, it will drive the entire elastic locking member 4 to produce elastic deformation with the first end 41 as the fulcrum, causing the locking section 44 of the second end 42 to shift into the first relief groove 281, thereby releasing the locking state with the second side wall 14, and the top cover 1 can be opened, making the unlocking operation of the top cover 1 effortless and effective.

[0062] Furthermore, such as Figure 10 , Figure 12 and Figure 13 As shown, the snap-fit ​​section 44 has a first snap-fit ​​portion 45 on the side away from the receiving groove 3; each of the two second sidewalls 14 has a snap-fit ​​groove 15 on the opposite side, and one end of one second sidewall 14 away from the cover plate 13 extends towards the other second sidewall 14 to form a second snap-fit ​​portion 16, which constitutes part of the sidewall of the snap-fit ​​groove 15; when the upper cover 1 is in the closed state, the first snap-fit ​​portion 45 is partially placed in the snap-fit ​​groove 15, and the second snap-fit ​​portion 16 is placed on the side of the first snap-fit ​​portion 45 away from the groove opening of the receiving groove 3, so as to fix the first snap-fit ​​portion 45 in the snap-fit ​​groove 15.

[0063] Specifically, one end of the second sidewall 14 away from the cover plate 13 is bent to form a second engaging portion 16. The second engaging portion 16 constitutes part of the sidewall of the engaging groove 15 on that side, that is, the engaging groove 15 is formed by a part of the body of the second sidewall 14 and the second engaging portion 16 together. When the upper cover 1 is flipped relative to the base 2 and is in a closed state, the engaging section 44 of the elastic locking member 4 is displaced under the action of its own elastic restoring force or external driving force, so that the first engaging portion 45 is at least partially placed in the engaging groove 15 of the second sidewall 14. At this time, the second engaging portion 16 is exactly located on the side of the first engaging portion 45 away from the opening of the receiving groove 3, that is, in the vertical direction, the second engaging portion 16 is located below the first engaging portion 45, to prevent the second engaging portion 16 from disengaging from the engaging groove 15.

[0064] In this embodiment, the first engaging part 45 engages with the engaging groove 15, and the second engaging part 16 is placed below the first engaging part 45 to prevent the elastic locking member 4 from sliding downward in the vertical direction and dislodging from between the two second side walls 14. Through the cooperation of the second engaging part 16 and the engaging groove 15, the first engaging part 45 is firmly constrained in the engaging groove 15, thereby ensuring the high reliability and stability of the upper cover 1 locking with the base 2 in the closed state. It can effectively resist accidental opening forces from different directions, significantly reduce the risk of the upper cover 1 accidentally popping open due to vibration or accidental touch, and better protect the electronic equipment 300 in the receiving groove 3 and the film application process.

[0065] Furthermore, such as Figure 10 and Figure 13 As shown, the first engaging part 45 is provided with a first guide surface 46 on the side away from the receiving groove 3. The first guide surface 46 gradually slopes away from the groove opening near the receiving groove 3 and away from the groove opening away from the receiving groove 3.

[0066] The first guide surface 46 begins near the opening of the receiving groove 3 (upper vertical end) and extends away from the opening of the receiving groove 3 (lower vertical end). Along this extension path, the first guide surface 46 gradually tilts away from the first clearance groove 281. When the upper cover 1 closes towards the base 2, the second engaging portion 16 on the second side wall 14 first contacts the first guide surface 46 of the first engaging portion 45. The tilted first guide surface 46 effectively guides the second engaging portion 16 to move below the first engaging portion 45, allowing the first engaging portion 45 to slide smoothly into the engaging groove 15. At the same time, it avoids direct rigid collision or interference between the first engaging portion 45 and the edge of the second side wall 14, reducing friction and wear between structures.

[0067] Furthermore, such as Figure 2As shown, the base 2 is provided with an elastic element 23, which is located between the elastic locking element 4 and the first end. When the upper cover 1 is in the closed state, the upper cover 1 presses the elastic element 23. When the second side wall 14 and the first side wall 28 are disengaged, the elastic element 23 elastically recovers and pushes the upper cover to rotate relative to the base, thereby disengaging the upper cover 1 from the elastic locking element 4 and making it easier to open the upper cover 1.

[0068] like Figure 2 and Figure 7 As shown, the elastic element 23 is located between the elastic locking element 4 and the hinge between the upper cover 1 and the base 2. That is, the elastic element 23 is located on the side of the elastic locking element 4 away from the tail end 22, so that when the upper cover 1 is in the closed state, the upper cover 1 covers and presses the elastic element 23. When the elastic locking element 4 is released from the second side wall 14, the constraint force applied to the elastic element 23 is released, and the elastic element 23 immediately restores its deformation, generating an upward thrust on the upper cover 1, which pops the upper cover 1 open, reducing the force required for the user to manually lift the upper cover 1, making the operation easier and less strenuous.

[0069] The first sidewall 28 is recessed towards the bottom wall of the receiving groove 3 with a second clearance groove 282. The elastic element extends along the length direction, with one end of the elastic element 23 connected to the sidewall of the second clearance groove 282, and the other end suspended in the second clearance groove 282. When the upper cover 1 is in the closed state, the upper cover 1 acts on the suspended end 231 of the elastic element 23. The second clearance groove 282 provides space for the elastic element 23 to accommodate and move, ensuring that the elastic element 23 can perform normal deformation and rebound movement without interfering with the upper cover 1. When the elastic locking element 4 releases the locking of the second sidewall 14, the elastic element 23 will immediately restore its deformation, applying a clear pushing force to the upper cover 1 through the suspended end 231, and popping the upper cover 1 open to an initial angle, which greatly facilitates the user's subsequent operation of fully opening the upper cover 1, improving the convenience of use and the smoothness of the experience.

[0070] Furthermore, such as Figure 8 and Figure 9 As shown, the cover plate 13 has a protrusion 17 located between the two second side walls 14. When the upper cover 1 is closed, the end of the protrusion 17 away from the cover plate 13 abuts against the elastic member 23. When the upper cover 1 is closed, the squeezing force of the protrusion 17 acts on the suspended end 231 of the elastic member 23, causing the suspended end 231 to move into the second clearance groove 282. At this time, the elastic member 23 has elastic potential energy. When the elastic locking member 4 and the second side wall 14 are disengaged, the elastic member 23 recovers its deformation and springs the upper cover 1 open. By providing the protrusion 17 on the cover plate 13, the squeezing degree of the upper cover 1 on the elastic member 23 can be further increased, ensuring that when the elastic locking member 4 and the second side wall 14 are disengaged, the upper cover 1 can be springed open by the elastic member 23.

[0071] Furthermore, the first end 21 of the base 2 and the upper cover 1 are movably connected by a shaft hole and a rotating shaft. A hinge is provided at the first end 21 of the base 2, and a mating part is provided on the upper cover 1. The hinge and the mating part are connected, allowing the upper cover 1 to rotate relative to the base 2.

[0072] In one implementation, such as Figure 2 and Figure 8 As shown, the hinge part is provided with at least two first shaft holes 291, and the mating part is provided with a corresponding first rotating shaft 181. The first rotating shaft 181 is partially placed in the first shaft hole 291, and the upper cover 1 is hinged to the first end 21 of the base 2.

[0073] In another implementation, such as Figure 3 and Figure 6 , Figure 7 As shown, the hinge part is provided with at least two second shaft holes 182, and the mating part is provided with a corresponding second rotating shaft 292. The second rotating shaft 292 is partially placed in the second shaft hole 182, and the upper cover 1 is hinged to the first end 21 of the base 2.

[0074] Each second rotating shaft 292 is partially placed within a second shaft hole 182. At least two reinforcing members 183 are provided at the end of the second shaft hole 182 away from the second rotating shaft 292, and adjacent reinforcing members 183 are spaced apart. The reinforcing members 183 enhance the mechanical strength of the second shaft hole 182, ensuring that the top cover 1 remains stable and reliable after repeated opening and closing, thus extending the service life of the equipment. Example 2

[0075] like Figure 14 As shown, based on the film application device 100 provided in Embodiment 1 above, this embodiment provides a film application assembly. This assembly includes any of the film application devices 100 provided in Embodiment 1 above and a protective film assembly 200 for applying films to electronic devices. The protective film assembly is disposed on the base and located above the receiving groove, as shown below. Figure 15As shown, the protective film assembly 200 includes a main film 201 and a first separation film 202 and a second separation film 203 respectively disposed on the upper and lower sides of the main film 201. The size of the first separation film 202 is larger than the size of the receiving groove 3. The second separation film 203 is provided with a tear-off piece 204 for removing the second separation film 203 from the main film 201. In the film application assembly provided in this embodiment, by setting the length of the upper cover 1 in the film application device 100 to be less than the length of the receiving groove 3, when the upper cover 1 is in the closed state, part of the receiving groove 3 is covered by the upper cover 1, and the other part is exposed, forming a natural observation window 5. This allows the user to visually inspect the adhesion between the protective film and the screen in real time throughout the entire film application process, and promptly detect and deal with defects such as bubbles, dust, or positional misalignment. This transforms the traditional fully enclosed film application into a visual film application, greatly improving the accuracy and success rate of film application.
