Description

A film application device Technical Field

[0001] This application belongs to the field of film application tool technology, and more specifically, this application is a film application device. Background Technology

[0002] Mobile phones, tablets, and other electronic devices are becoming increasingly common in our lives. During use, the surfaces of these devices (such as screens or other surfaces) are easily scratched, affecting their usability. To prevent this, users often apply a protective film to the surface of their electronic devices.

[0003] However, screen protector application usually involves manually peeling off the outer protective layer of the screen protector assembly and then applying the film. This process is complex and cannot be completed in one step. Furthermore, because the application process is not done in one go, it's difficult to ensure a dust-free environment. Dust may get between the electronic device and the screen protector during the interval between completely peeling off the outer protective layer and applying the film, and air bubbles can easily form, affecting the application effect and normal use. Summary of the Invention

[0004] This application provides a film application device that can automatically peel and apply the film simultaneously. It is simple to operate and improves the efficiency of film application. By completing the peeling and application of the film in one go, it can prevent dust from entering between the electronic device and the protective film body, and also reduce air bubbles, thus improving the quality of film application.

[0005] This application provides a film application device, including a base, a protective film assembly, a sliding seat, and a driving mechanism.

[0006] The sliding seat is mounted on the base and can slide relative to the base;

[0007] The sliding seat is provided with a compartment for placing electronic devices.

[0008] The protective film assembly includes a first protective film, a protective film body, and a second protective film stacked sequentially. The first protective film is connected to the sliding seat, and the second protective film is connected to the base.

[0009] The driving mechanism includes a power storage component, which, when triggered, drives the sliding seat to slide relative to the base with the electronic device, so that the second protective film separates from the protective film body, and then the protective film body is attached to the surface of the electronic device. Beneficial effects

[0010] The beneficial effects of this application are as follows: The film application device of this application provides driving force by releasing mechanical energy through the energy storage component, which drives the sliding seat to slide relative to the base with the electronic device and the protective film body. Since the first protective film is connected to the base, the first protective film is gradually peeled off from the protective film body. The protective film body falls and adheres to the surface of the electronic device. Automatic film peeling and film application can be realized at the same time. The operation is simple and the film application efficiency is improved. Moreover, by completing the film peeling and film application in one go, dust can be avoided from entering between the electronic device and the protective film body. At the same time, air bubbles are reduced and the film application quality is improved. Attached Figure Description

[0027] This application specifically discloses a film application device, as shown in FIG1, including a base 1, a protective film assembly 2, a sliding seat 3, and a driving mechanism 4 (as shown in FIG7 and FIG9). The sliding seat 3 is mounted on the base 1 and can slide relative to the base 1. The sliding seat can slide along the length direction of the base. The base has a first end and a second end arranged opposite to each other along its own length direction. The sliding seat slides towards the first end of the base as shown in FIG1 (front), and slides towards the second end of the base as shown in FIG1 (rear). Hereinafter, the first end can be described as the front end, and the second end as the rear end. The sliding seat 3 can slide out of the base 1, and the rear end of the base 1 is the end of the sliding seat 3 that slides out of the base 1. The width direction is perpendicular to the length direction of the base 1. As shown in Figure 2, the upper surface of the base 1 is provided with a receiving groove 11, which is used to receive the sliding seat 3. The rear end of the receiving groove 11 is provided with an opening, which serves as the sliding outlet for the sliding seat 3. The sliding seat 3 can slide into the receiving groove 11 by sliding towards the front end of the base 1, and it can slide out of the receiving groove 11 by sliding towards the rear end of the base 1. In the initial state, the sliding seat 3 is located in the receiving groove 11 and locked in the receiving groove 11.

[0028] Optionally, the sliding seat 3 and the base 1 are slidably connected by a sliding assembly, so that the sliding seat 3 can slide relative to the base 1 in the front-back direction. As shown in Figures 2-4, the sliding assembly includes a sliding guide 14 and a sliding member 34 that matches the sliding guide 14. The sliding guide 14 is disposed on the base 1, and the sliding member 34 is disposed on the sliding seat 3. The sliding member 34 can slide along the sliding guide 14.

[0029] The number of sliding guide 14 and sliding member 34 can both be one. In this case, it is optional that the sliding guide 14 is disposed on the bottom surface of the receiving groove 11 of the base 1 and is located at the center of the receiving groove 11 along the width direction, and the sliding member 34 is disposed at the center of the bottom of the sliding seat 3 along the width direction.

[0030] The number of sliding guide members 14 and sliding members 34 can both be two. In this case, optionally, the two sliding members 34 are disposed at the bottom of the sliding seat 3 and maintain a preset distance from each other, or are disposed on the two side walls of the sliding seat 3 respectively. Correspondingly, the two sliding guide members 14 are disposed in the receiving groove 11 of the base 1 and are respectively positioned corresponding to the two sliding members 34. In this embodiment, as shown in FIG2, the bottom of the receiving groove 11 of the base 1 is provided with two opposing sliding guide members 14. As shown in FIG3 and 4, the two side walls of the sliding seat 3 are provided with sliding members 34 that match the sliding guide members 14.

[0031] In some embodiments, the sliding guide 14 may be a slide rail with a concave slide track fixed on the base 1 or a slide groove opened on the base 1, and the sliding member 34 may be a slider disposed on the sliding seat 3. The sliding member 34 is inserted into the sliding guide 14 and can slide along the sliding guide 14, so that the sliding seat 3 can slide relative to the base 1 in the front-back direction. Alternatively, the sliding guide 14 may be a slider disposed on the base 1, and the sliding member 34 may be a slide rail with a concave slide track fixed on the sliding seat 3 or a slide groove opened on the sliding seat 3. The sliding guide 14 is inserted into the sliding member 34, and the sliding member 34 can slide along the sliding guide 14, so that the sliding seat 3 can slide relative to the base 1 in the front-back direction.

[0032] In some embodiments, to reduce sliding friction resistance, the sliding guide 14 is a slide rail with a concave slide path or a slide groove provided on the base 1, and the sliding member 34 is a slider provided on the sliding seat 3, which has a groove. The sliding member 34 is embedded in the sliding guide 14. As shown in Figures 2-4, the sliding assembly also includes a first roller 35 provided in front of the sliding member 34 on the sliding seat 3 and a second roller 15 provided at the rear end inside the sliding guide 14. The first roller 35 is rotatably connected to the sliding seat 3, and the second roller 15 is rotatably connected to the base 1. The second roller 15 is embedded in the groove of the sliding member 34, and the first roller 35 is embedded in the slide groove of the sliding guide 14 or the slide path of the slide rail. The sliding connection between the sliding seat 3 and the base 1 is achieved by the rolling of the first roller 35 along the sliding guide 14 and the rolling of the second roller 15 in the sliding member 34, thereby realizing the sliding of the sliding seat 3 relative to the base 1 in the front-back direction. The rotation of the first roller 35 and the second roller 15 enables the smooth movement of the slider 34 within the sliding guide 14, thereby reducing sliding friction.

[0033] As shown in Figures 1 and 3, the sliding seat 3 is provided with a receiving compartment 31 for placing the electronic device 20. The electronic device 20 is placed in the receiving compartment 31, which can fix the position of the electronic device 20. Preferably, the receiving compartment 31 on the sliding seat 3 is provided with limiting posts 32 on its four sides. The limiting posts 32 are engaged with the four sides of the electronic device 20 to position the electronic device 20 and ensure the accurate position of the electronic device 20.

[0034] As shown in Figure 5, the protective film assembly 2 includes a first protective film 21, a protective film body 22, and a second protective film 23 stacked sequentially. The first protective film 21, the protective film body 22, and the second protective film 23 are stacked from top to bottom along the direction shown in the figure. The protective film body 22 serves as the main body of the electronic device's protective film and can be a commonly used protective film such as tempered glass or optical plastic film. The protective film body 22 is ultimately adhered to the surface of the electronic device 20, providing protection for its surface. The first protective film 21 can be attached to the upper surface of the protective film body 22, completely covering it, to protect unused parts of the protective film body 22. Alternatively, the first protective film 21 can be attached to the second end (i.e., the rear end) of the protective film body 22, partially overlapping it, to fix the protective film body 22 in place. The second protective film 23 is used to protect unused parts of the protective film body 22. The second protective film 23 is attached to the lower surface of the protective film body 22 and can be a release film. The first protective film is connected to the sliding seat, and the second protective film is connected to the base. The rear end of the first protective film 21 can be connected to the sliding seat 3 at the rear of the accommodating compartment 31, and the front end of the second protective film 23 can be connected to the front end of the base 1.

[0035] Optionally, the rear end of the first protective film 21 is provided with at least one first positioning part 211. The first positioning part 211 extends outward from the rear end of the protective film body 22 and is integrally formed with the first protective film 21. The first positioning part 211 can be connected to the position behind the receiving compartment 31 on the sliding seat 3 to keep the protective film body 22 fixed to the sliding seat 3. When the rear end of the first protective film 21 is provided with one first positioning part 211, the first positioning part 211 is located at the center position in the width direction of the first protective film 21. When the rear end of the first protective film 21 is provided with two or more first positioning parts 211, all the first positioning parts 211 are arranged along the width direction of the first protective film 21 to improve the connection strength with the sliding seat 3. The front end of the second protective film 23 is provided with at least one second positioning part 231. The second positioning part 231 extends outward from the front end of the protective film body 22 and is integrally formed with the second protective film 23. The second positioning part 231 can be connected to the front end of the base 1. When the front end of the second protective film 23 is provided with a second positioning part 231, the second positioning part 231 is located at the center position in the width direction of the second protective film 23; when the front end of the second protective film 23 is provided with two or more second positioning parts 231, all the second positioning parts 231 are arranged along the width direction of the second protective film 23 to improve the connection strength with the base 1. As shown in FIG1, when the protective film assembly 2 covers the surface of the electronic device 20 in the housing 31, the first positioning part 211 is connected to the position behind the housing 31 on the sliding seat 3, the second positioning part 231 is connected to the front end of the base 1, and the connection point between the second positioning part 231 and the base 1 is located in front of the sliding seat 3.

[0036] Optionally, the first positioning part 211 can be connected to the sliding seat 3 by one of the following methods: adhesive bonding, magnetic attraction, or hooking the positioning hole to the protrusion. The second positioning part 231 can be connected to the base 1 by one of the following methods: adhesive bonding, magnetic attraction, or hooking the positioning hole to the protrusion. Adhesion can be achieved using double-sided adhesive. When the first positioning part 211 and the sliding seat 3 are connected, the top surface of the double-sided adhesive is bonded to the first positioning part 211, and the bottom surface is bonded to the upper surface of the sliding seat 3. When the second positioning part 231 is connected to the base 1, the top surface of the double-sided adhesive is bonded to the second positioning part 231, and the bottom surface is bonded to the upper surface in front of the receiving groove 11 of the base 1. For magnetic fixation, a first magnetic attractor and a second magnetic attractor are respectively fixed to the first positioning part 211 and the sliding seat 3, and a first magnetic attractor and a second magnetic attractor are respectively fixed to the second positioning part 231 and the base 1. When using a fixing method that connects positioning holes and protruding posts, positioning holes are provided on the first positioning part 211 and the second positioning part 231, and protruding posts are provided on the upper surfaces of the sliding seat 3 and the base 1. The number of positioning holes on the first positioning part 211 and the second positioning part 231 can be one or two, preferably two, with a predetermined distance between the two positioning holes; the number and position of the protruding posts are the same as the number and position of the matching positioning holes. As shown in Figures 1 and 3, two first protruding posts 33 with a predetermined distance are provided on the upper surface behind the accommodating compartment 31 of the sliding seat 3. As shown in Figures 1 and 5, two first positioning holes 2111 are provided on the first positioning part 211, and the first positioning part 211 is fitted onto the first protruding post 33 through the first positioning holes 2111. As shown in Figures 1 and 2, the front end receiving groove 11 of the base 1 is provided with two second protrusions 17 with a predetermined distance. As shown in Figures 1 and 5, the second positioning part 231 has two second positioning holes 2311, and the second positioning part 231 is sleeved on the second protrusions 17 through the second positioning holes 2311. Preferably, a horizontal first limiting post can be provided at the top of the first protrusion 33. The first limiting post extends to the rear of the first protrusion 33, that is, the first protrusion 33 and the first limiting post form an inverted L-shape. The width of the first positioning hole 2111 in the front-rear direction is less than the sum of the widths of the first protrusion 33 and the first limiting post in the front-rear direction, which can prevent the first positioning part 211 from disengaging from the first protrusion 33 when the sliding seat 3 slides to the rear end of the base 1. Similarly, a horizontal second limiting post can also be provided at the top of the second protrusion 17. The second limiting post extends forward of the second protrusion 17, that is, the second protrusion 17 and the second limiting post form an inverted L shape. The width of the second positioning hole 2311 in the front-to-back direction is less than the sum of the widths of the second protrusion 17 and the second limiting post in the front-to-back direction, which can prevent the second positioning part 231 from disengaging from the second protrusion 17 when the sliding seat 3 slides towards the rear end of the base 1.

[0037] The driving mechanism 4 is used to drive the sliding seat 3 to slide towards the rear end of the base 1. The driving mechanism 4 includes a power storage component 41, which is used to release mechanical energy after being triggered to provide driving force for the driving mechanism 4, so that the driving mechanism 4 drives the sliding seat 3 to slide relative to the base with the electronic device 20. Specifically, it slides towards the rear end of the base 1 shown in the figure, so that the second protective film is separated from the protective film body, and then the protective film body 22 is attached to the surface of the electronic device 20. Since the first protective film 21 is connected to the sliding seat 3 through the first positioning part 211, when the sliding seat 3 slides towards the rear end of the base 1, the sliding seat 3 carries the electronic device 20, the protective film body 22 and the first protective film 21 to slide towards the rear end of the base 1; since the second protective film 23 is connected to the base 1 through the second positioning part 231, when the sliding seat 3 carries the electronic device 20, the protective film body 22 and the first protective film 21 to slide towards the rear end of the base 1, the second protective film 23 is gradually torn off from the protective film body 22, and the protective film body 22 falls on the surface of the electronic device 20 under the action of gravity, as shown in Figure 6. Automatic film tearing and film application can be realized at the same time, and the film application operation can be completed in one step.

[0038] Moreover, after the second protective film 23 is removed, the protective film body 22 immediately falls onto the surface of the electronic device 20, which can prevent dust from entering between the electronic device 20 and the protective film body 22, and also reduces air bubbles and improves the quality of film application.

[0039] To prevent the slider 3 from sliding completely out of the base 1, a limiting member can be used to restrict the sliding stroke of the slider 3. The limiting member includes a first limiting member 16 and a second limiting member 36 that cooperate with each other, as shown in Figure 2. The first limiting member 16 is a protruding structure on the bottom surface of the receiving groove 11 of the base 1, as shown in Figure 4. The second limiting member 36 is a protruding structure on the bottom surface of the slider 3. The first limiting member 16 is located at the rear of the base 1, and the second limiting member 36 is located at the front of the slider 3. When the second limiting member 36 slides with the slider 3 to the first limiting member 16, the sliding of the slider 3 can be stopped by the contact cooperation between the first limiting member 16 and the second limiting member 36. By limiting the sliding stroke of the slider 3, it can be ensured that the second protective film 23 can be completely removed at this time and the protective film body 22 is attached to the surface of the electronic device 20, thus completing the film application. Preferably, when there are two sliding members 34 distributed on both sides of the sliding seat 3, the second limiting member 36 can be located at the center of the width direction of the sliding seat 3, and the first limiting member 16 can be located at the center of the width direction of the base 1. In this embodiment, the front end of the first limiting member 16 is a vertical panel perpendicular to the upper surface of the base 1 and the rear end is an inclined panel extending toward the vertical panel. The front end of the second limiting member 36 is an inclined panel extending downward and the rear end is a vertical panel. When the second limiting member 36 moves with the sliding seat 3 until the vertical panel at the rear end of the second limiting member 36 is in contact with the vertical panel at the front end of the first limiting member 16, the sliding seat 3 no longer slides outward toward the base 1.

[0040] Another optional limiting method is as follows: when one of the sliding guide 14 and the sliding member 34 is a slider, a limiting plate can be set at the end of the groove or rail that cooperates with the slider to block further sliding of the slider, thereby limiting the sliding stroke of the slider; when the groove or rail is set on the base 1, the limiting plate is set at the rear end of the groove or rail; when the groove or rail is set on the sliding seat 3, the limiting plate is set at the front end of the groove or rail. When the sliding seat 3 slides to the point where the slider contacts the limiting plate, it can no longer slide, thereby limiting the sliding stroke of the sliding seat 3.

[0041] Optionally, the drive mechanism 4 includes a power storage component 41, a gear 42, and a rack 43 meshing with the gear 42. One of the gear 42 and the rack 43 is disposed on the sliding seat 3, and the other is disposed on the base 1. The gear 42 may be disposed at the bottom of the sliding seat 3, and the rack 43 may be disposed in the receiving groove 11 of the base 1; alternatively, the gear 42 may be disposed in the receiving groove 11 of the base 1, and the rack 43 may be disposed at the bottom of the sliding seat 3. In this embodiment, as shown in FIG4, the rack 43 is fixed to the bottom of the sliding seat 3, and as shown in FIG7, the gear 42 is disposed in the receiving groove 11 of the base 1. The power storage component 41 is connected to and cooperates with the gear 42 to store or release mechanical energy. When releasing mechanical energy, the power storage component 41 can drive the gear 42 to rotate. When the sliding seat 3 is fully on the base 1, the power storage component 41 is in a power storage state.

[0042] Furthermore, the energy storage component 41 is a coil spring, and a spindle 12 is provided on the base 1 or sliding seat 3 where the gear 42 is located. When the gear 42 is set on the sliding seat 3, the spindle 12 is provided at the bottom of the sliding seat 3, and the spindle 12 is close to the front end of the sliding seat 3. As shown in Figures 2 and 7, when the gear 42 is set on the base 1, the spindle 12 is provided in the receiving groove 11 of the base 1, and the spindle 12 is close to the rear end of the base 1. The inner end of the coil spring is fixed to the spindle 12, and the coil spring can be wound around the spindle 12. The outer end of the coil spring is fixedly connected to the gear 42. A receiving hole for receiving the coil spring can be opened on the gear 42, and the coil spring can be set inside the receiving hole of the gear 42; the gear 42 can also be set on one end face of the gear 42. In this embodiment, the gear 42 is a spur gear. To ensure the stability of the drive mechanism 4, gear 42 is rotatably connected to its base 1 or sliding seat 3 via a bearing. The bearing is located between gear 42 and its base 1 or sliding seat 3 and is coaxial with gear 42. One of the inner and outer rings of the bearing is fixedly connected to gear 42, and the other is fixedly connected to base 1 or sliding seat 3. When sliding seat 3 slides towards the first end of the base, that is, towards the front end of base 1, gear 42 rotates, causing a coil spring to contract and wrap around the spindle 12 to accumulate mechanical energy. When the coil spring recovers its deformation and releases mechanical energy, it drives gear 42 to rotate in the opposite direction, driving sliding seat 3, carrying electronic device 20, to slide towards the second end of the base, that is, towards the rear end of base 1. When sliding seat 3 is fully on base 1, the coil spring is in an energy storage state. When the energy storage component 41 is triggered, the coil spring releases mechanical energy to drive gear 42 to rotate. Through the meshing connection of gear 42 and rack 43, sliding seat 3 slides stably towards the second end (rear end) of base 1. After the film is applied, the sliding seat 3 can be pushed into the base 1. During the movement of the sliding seat 3 towards the front end of the receiving groove 11, the gear 42 rotates and the coil spring continuously accumulates mechanical energy. When the sliding seat 3 returns to the receiving groove 11 of the base 1, the coil spring returns to the energy storage state for the next film application, thus realizing the reuse of the film application device.

[0043] To improve sliding stability, as shown in Figures 4 and 7, the drive mechanism 4 includes two sets of energy-accumulating components 41, namely, two gears 42 and two racks 43. The two racks 43 are arranged opposite each other and symmetrically in the bottom surface of the sliding seat 3 or the receiving groove 11 of the base 1. The two gears 42 are positioned between the two racks 43, and the gears 42 and racks 43 are meshed one-to-one. Each gear 42 is connected to a coil spring. When the sliding seat 3 slides towards the front end of the base 1, the two coil springs simultaneously accumulate mechanical energy; when the two coil springs release the mechanical energy, they drive the sliding seat 3 to slide towards the rear end of the base 1. At this time, if there is only one sliding guide 14 and one sliding member 34, the sliding assembly can be positioned between the two gears 42.

[0044] In another optional embodiment, the drive mechanism 4 includes a power storage component 41, which is a compressible elastic element disposed in front of the sliding seat 3. The compressible elastic element abuts against the sliding seat 3 and the base 1. The elastic deformation direction of the compressible elastic element is along the sliding direction of the sliding seat, i.e., the front-to-back direction. When the sliding seat 3 slides towards the front end of the base 1, i.e., the front end of the base 1, the compressible elastic element is compressed. Specifically, the front end of the compressible elastic element is fixedly connected to the inner wall of the front end of the receiving groove 11 of the base 1, and the rear end of the compressible elastic element is fixedly connected to the front wall of the front end of the sliding seat 3. When the sliding seat 3 is completely within the receiving groove 11 on the base 1, the compressible elastic element is in a compressed state. After the power storage component 41 is triggered, the compressible elastic element is released from compression. Under the restoring elastic force of the compressible elastic element, the sliding seat 3 is pushed towards the rear end of the base 1. The compressible elastic element can be a spring or a sheet spring. The use of a compression-type elastic element simplifies the structure of the drive mechanism 4. Furthermore, the length and stiffness of the compression-type elastic element limit the sliding stroke of the sliding seat 3 towards the rear end of the base 1. The film peeling and application are completed precisely when the compression-type elastic element returns to its natural state. To ensure smooth sliding of the sliding seat 3, sliding damping can be increased. For example, damping elements can be placed between the sliding guide 14 and the sliding member 34, or damping materials can be used to increase damping, preventing the sliding seat 3 from sliding too quickly and thus ensuring the film application effect.

[0045] In this embodiment, by setting up the power storage component 41, the film peeling and film application can be realized simultaneously by simply triggering the power storage component 41, thus realizing semi-automation of the film application operation, which is simple to operate and improves the film application efficiency.

[0046] The film-applying device of this application embodiment further includes a locking mechanism 5 for locking the sliding seat 3 onto the base 1 and a triggering mechanism 6 for triggering the energy storage component 41 to release mechanical energy. The locking mechanism 5 includes a first locking member 51 disposed on the first end (i.e., the front end) of the base 1 and a second locking member 52 disposed on the first end (i.e., the front end) of the sliding seat 3. The first locking member 51 and the second locking member 52 can be locked together to lock the sliding seat 3 onto the base 1. The triggering mechanism 6 is used to release the locking of the first locking member 51 and the second locking member 52, thereby triggering the energy storage component 41 to release mechanical energy, providing driving force for the driving mechanism 4, and driving the sliding seat 3 to slide towards the rear end of the base 1. The number of locking mechanisms 5 can be one, with the first locking member 51 disposed at the center of the front end width direction of the base 1 and the second locking member 52 disposed at the center of the front end width direction of the sliding seat 3. The locking mechanism 5 can also be two, with two second locking members 52 respectively disposed on both sides of the front end of the sliding seat 3. The position of the first locking member 51 corresponds to the position of the second locking member 52. The locking mechanism 5 does not affect the setting of the sliding assembly. Preferably, as shown in Figures 4 and 7, the number of locking mechanisms 5 is one.

[0047] Optionally, the first locking member 51 and the second locking member 52 are hooked and locked together. The first locking member 51 is a hook, and the second locking member 52 is a hook, a pull ring, or a groove at the bottom of the sliding seat 3 that cooperates with the first locking member 51. As shown in Figures 7 and 8, the first locking member 51 is a hook located at the front end of the receiving groove 11 inside the base 1, with the hook head facing upwards. The second locking member 52 is a groove (groove opening facing downwards) located at the bottom of the front end of the sliding seat 3, or a hook (hook head facing downwards) or a pull ring (pulling ring horizontally) located on the front wall or bottom of the front end of the sliding seat 3 that matches the first locking member 51. The hook head of the first locking member 51 can hook the second locking member 52, locking the sliding seat 3 onto the base 1.

[0048] Optionally, the first locking member 51 and the second locking member 52 are magnetically locked together. The first locking member 51 and the second locking member 52 are mutually magnetic. The first locking member 51 is fixed to the front end of the receiving groove 11 inside the base 1, with its magnetic surface facing upwards. The second locking member 52 is fixed to the bottom front end of the sliding seat 3, with its magnetic surface facing downwards, and is positioned above the first locking member 51. When the sliding seat 3 slides to the front end of the receiving groove 11 of the base 1, the first locking member 51 and the second locking member 52 are magnetically locked together, securing the sliding seat 3 to the base 1. Both the first locking member 51 and the second locking member 52 may be magnetic; one of the first locking member 51 and the second locking member 52 may also be a magnet, while the other may be an iron structure.

[0049] The triggering mechanism 6 includes a compression-type elastic element, which is disposed on the base 1. The bottom of the compression-type elastic element is fixedly connected to the base 1, and the compression-type elastic element can be vertically fixed to the front end of the base 1 and is located in the receiving groove 11. The top of the compression-type elastic element extends above the base 1. The side of the compression-type elastic element is connected to the first locking member 51, which is disposed in the upper middle part of the compression-type elastic element. When the compression-type elastic element is triggered and compressed, it drives the first locking member 51 to move downward and away from the second locking member 52 to release the locking between the first locking member 51 and the second locking member 52, thereby releasing the mechanical energy of the energy storage component 41 to provide driving force for the drive mechanism 4.

[0050] In another possible embodiment, as shown in Figures 7 and 8, the triggering mechanism 6 includes a compression-type elastic element (not shown), a button 61, and a guide cylinder 62. The guide cylinder 62 is fixed to the base 1, and the compression-type elastic element is fixed inside the guide cylinder 62. As shown in Figure 8, the bottom of the guide cylinder 62 is closed, either by itself or through the base 1. The bottom of the compression-type elastic element is fixedly connected to the bottom of the guide cylinder 62 or the base 1. The button 61 is fixed to the top of the compression-type elastic element. The lower part of the button 61 is inside the guide cylinder 62 and can slide up and down relative to the guide cylinder 62. The top of the button 61 extends above the base 1 for hand pressing. When the button 61 is pressed down, the compression-type elastic element is compressed. The side of the button 61 is fixedly connected to the first locking member 51. An opening is provided on the side wall of the guide cylinder 62 for the first locking member 51 to slide up and down with the button 61. The first locking member 51 extends through the opening to the outside of the guide cylinder 62, and the contact between the first locking member 51 and the upper edge of the opening also limits the downward sliding stroke of the button 61 when pressed. The compression elastic member can be a spring or a spring sheet. The bottom end of the spring or spring sheet is fixedly connected to the bottom of the guide cylinder 62 or the base 1, and the top end of the spring or spring sheet is fixedly connected to the bottom end of the button 61. The button 61 and the guide cylinder 62 are slidably connected by a groove and a protrusion that cooperates with the groove. One of the inner wall of the guide cylinder 62 and the outer wall of the button 61 is provided with a protrusion, and the other is provided with a groove. When the button 61 is triggered and pressed, the compression elastic member is compressed, and the button 61 drives the first locking member 51 to move downward and away from the second locking member 52 to release the locking between the first locking member 51 and the second locking member 52, thereby releasing the mechanical energy of the energy storage component 41 to provide driving force for the drive mechanism 4. After the button is released, the restoring force of the compression elastic element causes the button 61 to reset. The guide cylinder 62 acts as a guide, making the up-and-down movement of the button 61 and the compression deformation of the compression elastic element more stable; the design of the button 61 makes the operator's pressing more comfortable and aesthetically pleasing.

[0051] Preferably, as shown in Figures 7 and 8, when the first locking member 51 is a hook, the first locking member 51 has a first inclined surface 511 on its side near the sliding seat 3. The first inclined surface 511 slopes downwards towards the sliding seat 3, as shown in Figure 4. The outer wall of the second locking member 52 has a second inclined surface 521 that matches the first inclined surface 511. When the sliding seat 3 slides towards the front end of the base 1, the second inclined surface 521 and the first inclined surface 511 adhere to and press the first locking member 51. The first locking member 51 moves downwards to compress the compression elastic element. The sliding seat 3 continues to slide towards the front end of the base 1. The first inclined surface 511 slides downwards along the second inclined surface 521 until the hook head hooks the second locking member 52. The compression elastic element resets, so that the first locking member 51 stably hooks the second locking member 52, locking the sliding seat 3 inside the base 1.

[0052] The compression-type elastic element can not only achieve stable locking of the first locking element 51 and the second locking element 52, but also efficiently release the locking of the first locking element 51 and the second locking element 52, so that the operator has a more comfortable pressing experience.

[0053] When the sliding seat 3 is fully within the receiving groove 11 of the base 1, the first locking member 51 and the second locking member 52 lock together to lock the sliding seat 3 onto the base 1. At this time, the energy storage component 41 is in an energy storage state, and the electronic device 20 can be placed in the receiving compartment 31 of the sliding seat 3 with the surface of the electronic device 20 to be covered facing upwards. The protective film assembly 2 is placed on the surface of the electronic device 20 to be covered. The protective film assembly 2 is positioned by the connection between the first positioning part 211 and the sliding seat 3 and the connection between the second positioning part 231 and the base 1. Then, the protective film body 22 is aligned with the surface of the electronic device 20 to be covered. Pressing the button 61 or the compression elastic member causes the first locking member 51 to move downwards away from the second locking member 52. The first locking member 51 is no longer locked with the second locking member 52 on the sliding seat 3. The energy storage component 41 releases mechanical energy to drive the gear 42 to rotate or restore its natural length, driving the sliding seat 3 to slide towards the rear end of the base 1. Simply pressing button 61 or triggering the power storage component 41 with a compression elastic element can simultaneously peel and apply the film, achieving semi-automation of the film application process.

[0054] In some embodiments, the film application device further includes a pressing roller 7, as shown in FIG7. The pressing roller 7 is rotatably disposed at the second end (i.e., the rear end) of the base 1 and located above the receiving chamber 31. It is used to roll the protective film body 22 when the sliding seat 3 slides towards the second end of the base (i.e., the rear end of the base 1), pressing the protective film body 22 onto the surface of the electronic device 20 to avoid the formation of air bubbles. Specifically, an inverted U-shaped bracket 13 is provided above the receiving groove 11 at the second end (i.e., the rear end) of the base 1. The pressing roller 7 is disposed inside the bracket 13 and rotatably connected to the bracket 13. When the sliding seat 3 carries the electronic device 20, the protective film body 22, and the first protective film 21 to slide towards the rear end of the base 1, it drives the pressing roller 7 to rotate. The pressing roller 7 rolls and presses the protective film body 22, eliminating air bubbles and adhering the protective film body 22 onto the surface of the electronic device 20.

[0055] When the sliding seat 3 slides toward the front end of the base 1, it is locked in place by the locking mechanism 5 when the sliding seat 3 slides to the side of the accommodating compartment 31 that is in front of the pressing roller 7, which is closer to the first end of the base.

[0056] In some embodiments, the film application device further includes a cleaning roller 8, which is rotatably disposed at the second end (i.e., the rear end) of the base 1 and located above the receiving chamber 31. The cleaning roller 8 is used to roll and remove dirt from the electronic device 20 when the sliding seat 3 slides towards the rear end of the base 1. As shown in Figures 7 and 9, the cleaning roller 8 is also rotatably disposed inside the bracket 13 on the base 1. A pressing roller is disposed on the side of the cleaning roller near the second end of the base, i.e., the cleaning roller 8 is disposed in front of the pressing roller 7. During the sliding of the sliding seat relative to the base, the cleaning roller contacts the surface of the electronic device and moves relative to the surface of the electronic device to remove dirt. The pressing roller contacts the surface of the first protective film and moves relative to the surface of the first protective film to adhere the protective film body to the surface of the electronic device. Specifically, the lower part of the cleaning roller 8 can contact the electronic device 20, and the upper part of the cleaning roller 8 can contact the second protective film 23. When the sliding seat 3 slides to the rear end of the base 1, the cleaning roller 8 rotates, and the electronic device 20 contacts the cleaning roller 8 sequentially from the rear end to the front end to achieve rolling cleaning.

[0057] Optionally, as shown in Figure 9, the cleaning roller 8 is rotatably connected to the base 1 via torsion springs 9. A torsion spring 9 is provided at each end of the cleaning roller 8, and the two ends of the cleaning roller 8 are rotatably fitted into the corresponding torsion springs 9. The two ends of the torsion springs 9 are arranged vertically to be fixedly connected to the base 1. Specifically, one end of the torsion spring 9 is fixedly connected to the top plate of the bracket 13 of the base 1. A slot 131 can be provided on the top plate of the bracket 13, and the end of the torsion spring 9 is inserted into the slot 131. An insertion hole 132 is provided on the side plate of the bracket 13, and the other end of the torsion spring 9 is inserted into the insertion hole 132. Two torsion springs 9 are distributed on both sides of the bracket 13, and the two ends of the cleaning roller 8 are respectively inserted into the corresponding torsion springs 9, allowing the cleaning roller 8 to rotate within the torsion springs 9. The torsion springs 9 allow the cleaning roller 8 to be subjected to elastic downward pressure, ensuring the cleaning roller 8 adheres to the electronic device 20, pressing the wheel surface of the cleaning roller 8 onto the electronic device 20, thus ensuring the cleaning effect.

[0058] In some embodiments, the cleaning roller 8 includes an elastic roller and alcohol-absorbing cotton wrapped around the elastic roller. The elastic roller has an alcohol chamber inside, which stores alcohol. A through hole communicating with the alcohol chamber is provided on the axial surface of the elastic roller. Two torsion springs 9 are inserted into the two ends of the elastic roller, and the alcohol chamber and alcohol-absorbing cotton are located between the two torsion springs 9. Preferably, the length of the alcohol chamber along the axial direction of the elastic roller and the length of the alcohol-absorbing cotton along the axial direction of the elastic roller are greater than or equal to the width of the surface of the electronic device 20 to be covered with the film. The through hole is initially closed to prevent alcohol evaporation. When the sliding seat 3 slides towards the rear end of the base 1, the elastic roller rotates while being squeezed by the electronic device 20, opening the through hole and releasing the alcohol. The alcohol flows out from the alcohol chamber and is absorbed into the alcohol-absorbing cotton. The alcohol-absorbing cotton, now containing alcohol, rolls and wipes away dust and other impurities on the electronic device 20. Furthermore, the alcohol is volatile and does not affect the adhesion between the protective film body 22 and the electronic device 20.

[0059] Preferably, the elastic roller can be made of rubber, and the alcohol-absorbing cotton can be a sponge.

[0060] In another possible embodiment, the cleaning roller 8 includes a roller and multiple layers of cleaning adhesive tape disposed on the roller. Both ends of the roller are inserted into corresponding torsion springs 9, with the cleaning adhesive tape positioned between the two torsion springs 9. The length of the cleaning adhesive tape along the axial direction of the roller is greater than or equal to the width of the surface of the electronic device 20 to be covered with film. When the sliding seat 3 slides towards the rear end of the base 1, the outermost layer of cleaning adhesive tape rolls and removes dust and other impurities from the surface of the electronic device 20. After one layer of film is applied, the outermost layer of cleaning adhesive tape containing impurities can be peeled off, and the next layer of cleaning adhesive tape can be used for the next film application, enabling the cleaning roller 8 to be used multiple times. The adhesiveness of the cleaning adhesive tape is set as needed to ensure that it does not affect the removal of the second protective film 23.

[0061] When the film application device is equipped with both a pressing roller 7 and a cleaning roller 8, as the sliding seat 3 slides towards the front end of the base 1, it is locked in place by the locking mechanism 5 when the second end of the receiving chamber 31 is directly below the cleaning roller 8 or the cleaning roller is near the first end of the base (i.e., in front of the cleaning roller). Preferably, the sliding seat 3 is locked in place by the locking mechanism 5 when it slides to the point where the end of the receiving chamber 31 is directly below the cleaning roller 8. That is, in the initial state, the cleaning roller 8 is exactly at the rear end of the electronic device 20, and cleaning begins from the rear end of the electronic device 20. When the protective film assembly 2 is placed on the surface of the electronic device 20, the rear end of the second protective film 23 is above the cleaning roller 8. The first positioning part 211 passes over the cleaning roller 8 and then extends from below the pressing roller 7 to the rear of the pressing roller 7 and connects with the sliding seat 3. The pressing roller 7 is above the rear end of the protective film assembly 2. During the sliding process of the sliding seat 3 towards the rear end of the base 1, the cleaning roller 8 is always below the second protective film 23 to avoid contact with the protective film body 22 and affecting the adhesion of the protective film body 22.

[0062] In some embodiments, as shown in FIG10, the film application device of this application embodiment is further provided with a protective cover 10. The protective cover 10 can be covered on the base 1. The protective cover 10 is connected to the base 1. The sliding seat 3 is located in the space enclosed by the protective cover 10 and the base 1. The protective cover 10 plays a protective role when the film application device is not in use, and is used to protect the internal structures such as the sliding seat 3 and the drive mechanism 4. It can also be used for dust and water protection. The protective cover 10 can be detachably connected to the base 1, for example, by means of a protrusion and a groove snap-fit, allowing the protective cover 10 to be removed during film application; alternatively, it can be hinged on one side. Preferably, the front end of the base 1 is hinged to the protective cover 10, allowing the protective cover 10 to rotate and open towards the front end of the base 1 during film application; alternatively, the protective cover 10 and the base 1 can be connected by a through hole and protrusions. The front side wall of the base 1 has two opposing protrusions, and the front end of the protective cover 10 has a through hole. The protective cover 10 is fitted onto the protrusions through the through hole and can rotate around the protrusions, allowing the protective cover 10 to rotate around the protrusions and open towards the front of the base 1 during film application. This application does not impose any special limitations on the specific connection method between the protective cover 10 and the base 1, as long as it can be opened during film application and does not affect the application process.

[0063] One method for applying a film using the film-applying device according to an embodiment of this application is as follows:

[0064] With the protective cover 10 in place, first open the protective cover 10 to expose the base 1 and the sliding seat 3. Without the protective cover 10, subsequent operations can be performed directly. In the initial state, the sliding seat 3 is inside the receiving groove 11 of the base 1. At this time, the power storage component 41 is in the power storage state, and the first locking component 51 is locked with the second locking component 52 on the sliding seat 3. Place the electronic device 20 in the receiving compartment 31 of the sliding seat 3 to achieve positioning of the electronic device 20, with the surface of the electronic device 20 to be covered facing upwards. Place the protective film assembly 2 on the electronic device 20, with the rear end of the second protective film 23 positioned above the cleaning roller 8. The cleaning roller 8 is positioned directly above the rear end of the electronic device 20 and below the rear end of the second protective film 23. Extend the first positioning part 211 through the underside of the pressing roller 7 to the rear end of the sliding seat 3. The first positioning part 211 is connected to the rear end of the sliding seat 3, and the second positioning part 231 is connected to the front end of the base 1, thus achieving positioning of the protective film assembly 2. Pressing down button 61 or the compression elastic element triggers the energy storage component 41, disengaging the first locking component 51 from the second locking component 52 on the sliding seat 3. The energy storage component 41 releases mechanical energy, driving the sliding seat 3 to slide outward from the base 1. The sliding seat 3 carries the electronic device 20, the protective film body 22, and the first protective film 21 towards the rear end of the base 1. Since the second positioning part 231 is connected to the base 1, as the sliding seat 3 slides, the second protective film 23 is gradually peeled off from the rear end to the front end of the protective film body 22. During the sliding process of the sliding seat 3, the cleaning roller 8 rolls, and the electronic device 20 contacts the cleaning roller 8 sequentially from the rear end to the front end, achieving cleaning. The pressing roller 7 rolls, and the protective film body 22 is rolled sequentially from the rear end to the front end by the pressing roller 7, pressing the protective film body 22 onto the surface of the electronic device 20 to avoid air bubbles. The sliding seat 3 stops sliding when the second limiting member 36 moves to the position of the first limiting member 16, completing the film application. At this point, remove the electronic device 20 with the protective film body 22 and the first protective film 21 attached, and peel off the first protective film 21 to completely complete the film application. The entire film application process is simple to operate, and the film peeling and application can be completed simultaneously. It also achieves both dirt removal and pressing of the film, avoiding dust and air bubbles from affecting the film application effect, greatly improving the efficiency and quality of film application. Furthermore, the positioning function of the first positioning part 211 and the second positioning part 231 avoids the problem of film misalignment.

[0065] After the film is applied, the sliding seat 3 can be pushed towards the front end of the base 1. During this process, the energy storage component 41 continuously accumulates mechanical energy until the sliding seat 3 slides to a position where the end of the receiving chamber 31 is directly below the cleaning roller 8 or on the side of the cleaning roller near the first end of the base (i.e., in front of the cleaning roller). At this point, the first locking member 51 locks with the second locking member 52 on the sliding seat 3, locking the sliding seat 3 in the receiving groove 11 of the base 1, ready for the next film application. This enables the film application device to be reused.

[0066] In this application, the electronic device 20 refers to electronic devices such as mobile phones and tablet computers.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and simple improvements made to the substantive content of the embodiments of this application should be included within the protection scope of this application.
