Description

Technical Field

[0001] This application relates to the field of film application tools, and in particular to a film applicator and film application device. Background Technology

[0002] A screen protector applicator is a tool used to apply screen protectors to mobile phones and other devices. To ensure portability, screen protectors typically only allow one protective film component to be installed. This means that a new protective film component must be inserted before the applicator can be used again, which is inconvenient. Utility Model Content

[0003] An embodiment of this application provides a film applicator, which includes a housing assembly. A first mounting position and a second mounting position are formed inside the housing assembly. The first mounting position is used to install a first protective film assembly, and the second mounting position is used to install a second protective film assembly. The first mounting position and the second mounting position are isolated from each other, and the first mounting position and the second mounting position are arranged along the thickness direction of the housing assembly.

[0004] The housing assembly includes a first base and a first cover that are movably connected. The first base has a first opening on one side, and at least one of a first mounting position and a second mounting position is formed inside the first base.

[0005] The housing assembly has a first state and a second state; in the first state, a first cover is placed over a first opening; in the second state, the first opening is at least partially connected to the outside, so that the first mounting position or the second mounting position is connected to the outside; wherein, the housing assembly switches between the first state and the second state by the movement of the first cover relative to the first base.

[0006] Embodiments of this application also provide a film application device, the film application device comprising:

[0007] A film applicator includes a housing assembly, inside which a first mounting position and a second mounting position are formed, the first mounting position and the second mounting position are isolated from each other, and the first mounting position and the second mounting position are arranged along the thickness direction of the housing assembly;

[0008] A first protective film assembly is installed at a first mounting position; and

[0009] The second protective film assembly is installed at the second mounting position;

[0010] The first protective film assembly and the second protective film assembly are stacked at intervals; the housing assembly includes a first base and a first cover that are movably connected, a first opening is provided on one side of the first base, and at least one of the first mounting position and the second mounting position is formed inside the first base;

[0011] The housing assembly has a first state and a second state; in the first state, a first cover is placed over a first opening; in the second state, the first opening is at least partially connected to the outside, so that the first mounting position or the second mounting position is connected to the outside; wherein, the housing assembly switches between the first state and the second state by the movement of the first cover relative to the first base.

[0012] The beneficial effects of the film applicator provided in this application are:

[0013] This application forms two isolated mounting positions inside the housing assembly and arranges these two mounting positions along the thickness direction of the housing assembly. This allows the applicator to simultaneously install two protective film components without making the applicator too large. Thus, the applicator has the capability to apply film twice to the device to be filmed. When a second application is needed, no new protective film component needs to be installed, which improves the convenience of film application and avoids a significant decrease in the portability of the applicator. Furthermore, this application forms at least one of the first and second mounting positions inside the first base of the housing assembly and movably connects the first cover of the housing assembly to the first base. This allows the housing assembly to switch between a first state and a second state through the movement of the first cover relative to the first base. When idle, the applicator can adjust the housing assembly to the first state, with the first cover covering the first opening of the first base to prevent external impurities from entering the first base through the first opening.

[0032] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only a part of the embodiments of this application, and not all of them.

[0034] This application provides a film application device and its applicator. The film application device includes an applicator and a protective film assembly installed in the applicator, and can be used to apply films to external devices. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of the film-applying device provided in some embodiments of this application in its first state. Figure 2 yes Figure 1 The diagram shows a three-dimensional structure of the film-applying device in its second state.

[0035] The film application device 10 includes a film applicator 11, which can be used to install a protective film assembly and to apply a film to external devices. The film applicator 11 includes a housing assembly 100. In some embodiments, the housing assembly 100 may include a first base 110 and a first cover 120, with a first opening 101 on one side of the first base 110. The housing assembly 100 may have a first state and a second state. In the first state, the first cover 120 covers the first opening 101. In the second state, the first opening 101 is at least partially in communication with the outside. The housing assembly 100 switches between the first state and the second state by the movement of the first cover 120 relative to the first base 110.

[0036] When the protective film assembly or the device to be applied needs to be inserted into or removed from the housing assembly 100, the housing assembly 100 can switch from a first state to a second state. After the insertion or removal process is completed, the housing assembly 100 can switch from the second state to the first state, so that the film applicator 11 can apply the film or be idle.

[0037] Optionally, the first base 110 is hinged to the first cover 120. For example... Figure 2As shown, one end of the first cover 120 can be hinged to one end of the first base 110. The housing assembly 100 can switch between a first state and a second state by rotating the first cover 120 relative to the first base 110. In other embodiments, the movable connection between the first base 110 and the first cover 120 is not limited to this, and will be described separately below.

[0038] It should be understood that the terminology used in this specification and appended claims is for the purpose of describing particular embodiments only and is not intended to limit the application. As used in this specification and appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise. Similarly, the terms “first” and “second” in the description of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features. Furthermore, the term “multiple” in the description of this application means two or more, unless otherwise explicitly specified.

[0039] Please see Figure 3 and Figure 4 , Figure 3 yes Figure 1 An exploded view of the film-applying device in the embodiment. Figure 4 yes Figure 1 A cross-sectional view of the film-applying device in the embodiment.

[0040] The film application device 10 includes a film applicator 11, a first protective film assembly 12, and a second protective film assembly 13. In some embodiments, a first mounting position 102 and a second mounting position 103 are formed inside the housing assembly 100. The first mounting position 102 is used to mount the first protective film assembly 12, and the second mounting position 103 is used to mount the second protective film assembly 13. The first mounting position 102 and the second mounting position 103 are isolated from each other, and the first mounting position 102 and the second mounting position 103 are arranged along the thickness direction of the housing assembly 100. The first protective film assembly 12 mounted at the first mounting position 102 and the second protective film assembly 13 mounted at the second mounting position 103 can be stacked at intervals.

[0041] The housing assembly 100 may include a first base 110 and a first cover 120. A first mounting position 102 and a second mounting position 103 may both be formed inside the first base 110. In other embodiments, the first mounting position 102 or the second mounting position 103 may also be formed at other locations on the housing assembly 100, as will be described below. In the second state, the first opening 101 is at least partially connected to the outside, such that the first mounting position 102 or the second mounting position 103 is connected to the outside. For example, in the second state, the first opening 101 may be partially connected to the outside, in which case the first cover 120 may cover another portion of the first opening 101. Alternatively, in the second state, the first opening 101 may be fully connected to the outside, and the first cover 120 may not cover the first opening 101.

[0042] In some embodiments, the first substrate 110 has a first groove 104. A first opening 101 can be the groove opening of the first groove 104. A first mounting position 102 and a second mounting position 103 are both formed in the first groove 104. The applicator 11 may include a mounting member 200 disposed in the first groove 104. The mounting member 200 may have a first mounting position 102 and a second mounting position 103. The first mounting position 102 and the second mounting position 103 are respectively formed on opposite sides of the mounting member 200. The mounting member 200 is detachably connected to the first substrate 110. In other embodiments, the first opening 101 may also be an opening provided on the upper wall of the first substrate 110, and the first opening 101 communicates with the groove opening of the first groove 104.

[0043] The mounting component 200 may have grooves formed on its opposite sides to serve as a first mounting position 102 and a second mounting position 103. A first protective film assembly 12 and a second protective film assembly 13 are respectively disposed on opposite sides of the mounting component 200, and the disposal method may include, but is not limited to, using positioning pins and positioning holes, micro-adhesive fixing, pasting, or pressing. The first protective film assembly 12 and the second protective film assembly 13 may have the same or similar structures, and are installed on opposite sides of the mounting component 200 in opposite states, thus enabling the film application device 10 to provide two film applications for the device to be filmed.

[0044] Taking a mobile phone 20 as an example, when applying the screen protector, in some application scenarios, the housing assembly 100 is in a second state, the first mounting position 102 is connected to the first opening 101, and the first opening 101 is at least partially connected to the outside, so that the first mounting position 102 is connected to the outside, and the first protective film assembly 12 is exposed to the first opening 101; the mobile phone 20 can be inserted into the first groove 104 from the first opening 101 and placed on one side of the mounting member 200. At this time, the screen protector device 10 can apply the first protective film assembly 12 to the display screen of the mobile phone 20.

[0045] When a screen protector needs to be applied to another phone 20 after the screen protector application on phone 20 is completed, or when the screen protector application on phone 20 fails and needs to be reapplied, the screen protector application device 10 can remove the mounting part 200 from the first base 110, then flip the mounting part 200 and reinstall it into the first groove 104, so that the second mounting position 103 communicates with the first opening 101; in the second state, the first opening 101 is at least partially connected to the outside, so that the second mounting position 103 is connected to the outside, and the second protective film assembly 13 is exposed to the first opening 101; the phone 20 to be screen protectored can be inserted from the first opening 101 into the first groove 104 and placed on the other side of the mounting part 200. At this time, the screen protector application device 10 can apply the second protective film assembly 13 to the display screen of the phone 20.

[0046] Through the above design, the film application device 10 of this embodiment can provide two opportunities for film application without reinstalling the protective film assembly. Therefore, when a second application is needed, there is no need to install a new protective film assembly. After the first protective film assembly 12 is used, the second protective film assembly 13 can be used simply by flipping the mounting piece 200, which improves the convenience of film application. The first protective film assembly 12 and the second protective film assembly 13 are stacked at intervals along the thickness direction of the housing assembly 100, which avoids increasing the length or width of the housing assembly 100, thereby minimizing the reduction in the portability of the film application device 10.

[0047] Understandably, all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0048] Optionally, the mounting component 200 is provided with a positioning part 210 for contacting the device to be coated with the film, so as to position the device on the mounting component 200. The mounting component 200 can be a component that conforms to the contour of the mobile phone 20, used to accurately position the mobile phone 20. The mounting component 200 can be customized according to different models of mobile phones 20 to ensure that it can fit tightly to the shape of the mobile phone 20.

[0049] The positioning method of the positioning unit 210 for the mobile phone 20 can be selected according to the actual situation, and the specific structure of the positioning unit 210 can be set accordingly. For example, the positioning unit 210 can use the charging port of the mobile phone 20 for positioning. The positioning unit 210 can be a slot that matches the charging port of the mobile phone 20, so that the mobile phone 20 can be accurately placed in a preset position on the mounting member 200. Alternatively, the positioning unit 210 can use the four edges of the mobile phone 20 for positioning. The positioning unit 210 can be a groove or protrusion that matches the edge of the mobile phone 20, so that the mobile phone 20 can be accurately placed in a preset position on the mounting member 200.

[0050] Optionally, the applicator 11 includes a flexible support 300, the material of which is, for example but not limited to, cotton. The flexible support 300 may be disposed on one side of the mounting member 200 and exposed at the first mounting position 102 for pressing against the first protective film assembly 12. The flexible support 300 may also be disposed on the other side of the mounting member 200 and exposed at the second mounting position 103 for pressing against the second protective film assembly 13. For example... Figure 3 and Figure 4 As shown, a flexible support 300 can be provided on each of the opposite sides of the mounting component 200. The two flexible support 300 press against the first protective film assembly 12 and the second protective film assembly 13 respectively, so as to provide pre-pressure to the first protective film assembly 12 or the second protective film assembly 13 when it contacts the mobile phone 20, so as to lift it up and make it fit tightly against the display screen of the mobile phone 20, which helps to increase the possibility of successful film application.

[0051] The flexible support member 300 can be elongated and extends along the length of the mounting member 200. In other embodiments, the shape, arrangement, and number of the flexible support members 300 are not limited to this embodiment. For example, the applicator 11 may include a plurality of disk-shaped flexible support members 300 arranged in an array, or the applicator 11 may include elongated flexible support members 300 extending along the width of the mounting member 200.

[0052] Optionally, the film applicator 11 includes a fixing part 400. The fixing part 400 may protrude from the surface of the first cover 120. In a first state, the first cover 120 and the first base 110 may surround and form a receiving cavity 105. The fixing part 400 is located in the receiving cavity 105 and is used to fix the device to be applied. The fixing part 400 may be a flexible structure, such as cotton or soft rubber. The fixing part 400 may also be a rigid structure, such as hard rubber. The fixing part 400 may be a structural component connected to the first cover 120, and the connection method may be, for example, but not limited to, adhesive bonding. The fixing part 400 may also be integrally formed with the first cover 120.

[0053] The fixing part 400 can be used to fix the mobile phone 20 during the screen protector application process to ensure that the mobile phone 20 remains stable during the application. The fixing method is, for example, but not limited to, elastic clamping, suction cup fixing, or magnetic adsorption. The specific structure of the fixing part 400 and its arrangement on the first cover 120 can be set according to different fixing methods. When applying the screen protector, the first cover 120 can apply pressure to the fixing part 400 under the action of external force so that the fixing part 400 can press against the mobile phone 20. The external force on the first cover 120 can come from the user or from the connection structure between the first cover 120 and the first base 110. This connection structure is, for example, but not limited to, a snap-on connection structure, a button connection structure, etc. The housing assembly 100 can be designed with a corresponding structure according to the actual situation.

[0054] In some embodiments, the housing assembly 100 has a pull-out opening 106 communicating with the outside, and both the first protective film assembly 12 and the second protective film assembly 13 have pull-out portions 500. The pull-out portions 500 can be bent and located inside the housing assembly 100. The pull-out opening 106 can be formed on the first base 110, specifically on the side wall of the first groove 104. Before applying the film, the pull-out portion 500 can be completely accommodated in the first groove 104. During film application, the pull-out portion 500 can unfold and extend to the outside through the pull-out opening 106, allowing the user to pull it out for film application.

[0055] In this embodiment, the pull-out portion 500 is completely housed within the first groove 104 in the idle state, and the pull-out portion 500 is designed to be bent, so that the pull-out portion 500 can be unfolded during film application and has a length that can pass through the pull-out opening 106, thereby avoiding the problem of accidental pull-out of the film application device 10 in the idle state. In other embodiments, the pull-out portion 500 may also be inserted through the pull-out opening 106 in the idle state.

[0056] In some application scenarios, after the phone 20 is placed in the first groove 104 and comes into contact with the first protective film assembly 12, the first cover 120 is closed. At this time, the flexible support 300 and the fixing part 400 can press against the phone 20 and the first protective film assembly 12 from the top and bottom sides respectively, so that the phone 20 and the first protective film assembly 12 are in close contact. After the pull-out part 500 is pulled out, the first protective film assembly 12, which is in close contact with the phone 20, can complete the application on the phone 20. Understandably, the above-described film application process also applies to the second protective film assembly 13.

[0057] It should be understood that the terms "comprising" and "having," and any variations thereof, used in this application and the appended claims, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0058] Please refer to the above text. Figure 5 and Figure 6 , Figure 5 This is a three-dimensional structural schematic diagram of some of the film-applying devices provided in some embodiments of this application. Figure 6 yes Figure 5 The diagram shows an exploded view of part of the film application device.

[0059] In some embodiments, both the first protective film assembly 12 and the second protective film assembly 13 include a film body 121, a dust removal layer 122, and a protective layer 123. The dust removal layer 122 has a pull-out portion 500. The film body 121 is used to adhere to the device to which the film is to be applied. The dust removal layer 122 is detachably adhered to one side of the film body 121, and the protective layer 123 is detachably adhered to the side of the film body 121 opposite to the dust removal layer 122. Adhesive layers may be provided on both opposite sides of the film body 121, and the dust removal layer 122 and the protective layer 123 may be respectively adhered to the opposite sides of the film body 121.

[0060] The first mounting position 102 and the second mounting position 103 are respectively formed on opposite sides of the mounting member 200. The first protective film assembly 12 is disposed at the first mounting position 102, and the second protective film assembly 13 is disposed at the second mounting position 103. The protective layer 123 can contact the mounting member 200. In other words, the first protective film assembly 12 contacts one side of the mounting member 200 through its protective layer 123, and the second protective film assembly 13 contacts the other side of the mounting member 200 through its protective layer 123.

[0061] Optionally, the flexible support 300 is installed in the area of ​​the mounting member 200 that contacts the protective layer 123. The mounting member 200 may have a groove for accommodating the flexible support 300, allowing the flexible support 300 to be embedded in the mounting member 200 to prevent displacement when the dust removal layer 122 is pulled out. Displacement can also be prevented by bonding the flexible support 300 to the mounting member 200. Both the first protective film assembly 12 and the second protective film assembly 13 can contact the flexible support 300 through the protective layer 123.

[0062] In some application scenarios, in the second state, the first opening 101 is the top opening of the housing assembly 100, and the dust removal layer 122 of the first protective film assembly 12 is exposed through the first opening 101. The mobile phone 20 can be placed on one side of the mounting member 200 with the display screen facing down through the first opening 101 and in contact with the dust removal layer 122 of the first protective film assembly 12. When the pull-out portion 500 of the dust removal layer 122 is pulled out, the dust removal layer 122 will separate from the film body 121, at which point the film body 121 will be attached to the display screen of the mobile phone 20. After the film body 121 is adhered to the mobile phone 20, the protective layer 123 can be removed from the film body 121 to complete the film application.

[0063] After applying the film using the first protective film assembly 12, the film applicator 10 can flip the mounting member 200 to expose the dust removal layer 122 of the second protective film assembly 13 to the first opening 101, so that the film applicator 10 can reuse the second protective film assembly 13 for film application. In other embodiments, the film applicator 11 is not limited to the above structure, and other examples will be listed below.

[0064] Please see Figures 7 to 9 , Figure 7 This is a three-dimensional structural schematic diagram of the film-applying device provided in some embodiments of this application. Figure 8 yes Figure 7 An exploded view of the film-applying device in the embodiment. Figure 9 yes Figure 7 A cross-sectional view of the film-applying device in the embodiment.

[0065] In some embodiments, the first substrate 110 may have a first groove 104 and a second groove 107, the first groove 104 being isolated from the second groove 107, a first mounting position 102 being formed in the first groove 104, and a second mounting position 103 being formed in the second groove 107. A first opening 101 may be the opening of the first groove 104. The first substrate 110 may also have a second opening 108, which may be the opening of the second groove 107.

[0066] The first opening 101 and the second opening 108 can be respectively located on opposite sides of the first substrate 110. The first protective film assembly 12 can be installed in the first mounting position 102 through the first opening 101, and the second protective film assembly 13 can be installed in the second mounting position 103 through the second opening 108. The first protective film assembly 12 and the second protective film assembly 13 can be stacked alternately. The bottom wall of the first groove 104 and the bottom wall of the second groove 107 block the space between the first protective film assembly 12 and the second protective film assembly 13, and the bottom wall of the first groove 104 and the bottom wall of the second groove 107 are integral structures.

[0067] When applying the film, the film application device 10 can align one side of the first substrate 110 upwards, exposing the first protective film assembly 12 to the first opening 101 for film application. When a second film application is required, the film application device 10 can flip the housing assembly 100 so that the other side of the first substrate 110 faces upwards, exposing the second protective film assembly 13 to the second opening 108 for film application.

[0068] The housing assembly 100 may include a first cover 120 and a second cover 130.

[0069] The first cover 120 is movably connected to the first base 110, and the housing assembly 100 has a first state and a second state. In the first state, the first cover 120 covers the first opening 101. In the second state, the first opening 101 is at least partially connected to the outside. The housing assembly 100 switches between the first state and the second state through the movement of the first cover 120 relative to the first base 110.

[0070] The second cover 130 is movably connected to the first base 110, and the housing assembly 100 also has a third state and a fourth state. In the third state, the second cover 130 covers the second opening 108. In the fourth state, the second opening 108 is at least partially connected to the outside. The housing assembly 100 switches between the third state and the fourth state through the movement of the second cover 130 relative to the first base 110.

[0071] In this configuration, the first mounting position 102 is connected to the outside in the second state, and the second mounting position 103 is connected to the outside in the fourth state. In the second state, the film-applying device 10 can apply film using the first protective film assembly 12. In the fourth state, the film-applying device 10 can apply film using the second protective film assembly 13.

[0072] The arrangement of the first cover 120 and the second cover 130 on the first base 110 can be selected according to the actual situation.

[0073] For example, both the first cover 120 and the second cover 130 can be detachably connected to the first base 110. In the first state, the first cover 120 can overlap one side of the first base 110. In the second state, the first cover 120 can be separated from the first base 110. In the third state, the second cover 130 can overlap the other side of the first base 110. In the fourth state, the second cover 130 can be separated from the first base 110.

[0074] For example, at least one of the first cover 120 and the second cover 130 may be hinged to the first base 110, and the housing assembly 100 may be switched between a first state and a second state by rotating relative to the first base 110. Alternatively, at least one of the first cover 120 and the second cover 130 may be slidably connected to the first base 110, and the housing assembly 100 may be switched between a first state and a second state by sliding on the first base 110.

[0075] Understandably, the housing assembly 100 may be in one of the first and second states, as well as one of the third and fourth states. For example, when the film applicator 10 applies film using the first protective film assembly 12, the second cover 130 may be placed over the second opening 108. In this case, the housing assembly 100 may be in both the second and third states simultaneously.

[0076] In some embodiments, the applicator 11 has a mounting portion 600, which has a first mounting position 102 and a second mounting position 103. The mounting portion 600 can be a mounting member 200 disposed in the housing assembly 100. For example... Figure 8 and Figure 9 As shown, the applicator 11 may include two mounting members 200. One mounting member 200 has a first mounting position 102 and is disposed in a first groove 104, and the other mounting member 200 has a second mounting position 103 and is disposed in a second groove 107. The two mounting members 200 may be mounted on the bottom wall of the first groove 104 and the bottom wall of the second groove 107, respectively. The mounting members 200 may be connected to the first substrate 110, and the connection method may include, but is not limited to, snap-fit ​​or adhesive bonding.

[0077] The mounting member 200 may be provided with a positioning part 210 for contacting the device to be coated, thereby positioning the device on the mounting member 200. The positioning part 210 may be a protrusion on the surface of the mounting member 200, used to position the device by contacting its edge. There may be one or more positioning parts 210. Optionally, the first mounting position 102 and the second mounting position 103 may be formed by the positioning parts 210, for example... Figure 8 As shown, multiple positioning portions 210 may be spaced apart and arranged in a ring to enclose a space for placing the protective film assembly and the device to be applied. In other embodiments, the first mounting position 102 or the second mounting position 103 may also be enclosed by a single positioning portion 210.

[0078] In other embodiments, the positioning part 210 is not limited to the structure described above, and specific details can be found above. The first mounting position 102 and the second mounting position 103 are also not limited to being formed by the positioning part 210. For example, the first mounting position 102 can be formed by the mounting member 200 and the first base 110 in cooperation.

[0079] In this embodiment, the mounting portion 600 is not limited to the mounting member 200. In other embodiments, the mounting portion 600 can be the inner wall of the housing assembly 100, such as the groove wall of the first groove 104 and the groove wall of the second groove 107, so that the film applicator 11 does not need to be equipped with the mounting member 200, which helps to reduce costs and save space. When the inner wall of the housing assembly 100 is used as the mounting portion 600, a positioning portion 210 can be provided on the inner wall of the housing assembly 100. The first protective film assembly 12 can be installed on the bottom wall of the first groove 104, and the second protective film assembly 13 can be installed on the bottom wall of the second groove 107, wherein the bottom walls of the first groove 104 and the bottom walls of the second groove 107 are the same wall.

[0080] In other embodiments, the first base 110 may also be a hollow structure with a first opening 101 and a second opening 108 formed on its two sides respectively, and an internal space is formed to connect the two openings. The mounting member 200 may be disposed in the space to divide the space into two parts, which are respectively connected to the first opening 101 and the second opening 108.

[0081] Optionally, the film applicator 11 also includes a flexible support 300, which is disposed on the mounting portion 600 and exposed at the first mounting position 102 or the second mounting position 103, for pressing against the first protective film assembly 12 or the second protective film assembly 13. The specific design of the flexible support 300 has been described above and will not be repeated here.

[0082] Optionally, the applicator 11 further includes a fixing part 400. The fixing part 400 may protrude from the surface of the first cover 120. In a first state, the first cover 120 and the first base 110 form a receiving cavity 105, and the fixing part 400 is located in the receiving cavity 105 for fixing the device to which the first protective film assembly 12 is to be applied. In a third state, the second cover 130 and the first base 110 may form another receiving cavity 105, and the fixing part 400 may also protrude from the surface of the second cover 130. The fixing part 400 may be located in the receiving cavity 105 in the third state for fixing the device to which the second protective film assembly 13 is to be applied. For other designs of the fixing part 400, please refer to the description above.

[0083] In the above embodiments, both the first mounting position 102 and the second mounting position 103 are formed inside the first base 110. In other embodiments of this application, the first mounting position 102 or the second mounting position 103 may also be formed in other locations, with at least one of the first mounting position 102 and the second mounting position 103 formed inside the first base 110. Please refer to... Figures 10 to 13 , Figure 10 This is a three-dimensional structural diagram of the film-applying device provided in some embodiments of this application in its first state. Figure 11 yes Figure 10 An exploded view of the film applicator in the embodiment. Figure 12 yes Figure 10 A cross-sectional view of the film applicator in the embodiment.

[0084] In some embodiments, the housing assembly 100 may include a first base 110 and a second base 140. A first mounting position 102 may be formed inside the first base 110, and a second mounting position 103 may be formed inside the second base 140. The first base 110 may have a first groove 104, and a first opening 101 is provided on one side of the first base 110. The first opening 101 may be the groove opening of the first groove 104. The second base 140 may have a second groove 107, and a second opening 108 is provided on one side of the second base 140. The second opening 108 may be the groove opening of the second groove 107. The first mounting position 102 may be formed in the first groove 104, and the second mounting position 103 may be formed in the second groove 107. Similarly, in other embodiments, the first mounting position 102 may also be formed inside the second base 140, and the second mounting position 103 may be formed inside the first base 110.

[0085] The housing assembly 100 may further include a first cover 120 and a second cover 130. The first cover 120 is movably connected to the first base 110. In a first state, the first cover 120 covers the first opening 101. In a second state, the first opening 101 is at least partially in communication with the outside. The first mounting position 102 is in communication with the outside in the second state. The housing assembly 100 switches between the first state and the second state through the movement of the first cover 120 relative to the first base 110. The film application device 10 can apply film using the first protective film assembly 12 in the second state.

[0086] The second cover 130 is movably connected to the second base 140. In the third state, the second cover 130 covers the second opening 108. In the fourth state, the second opening 108 is at least partially connected to the outside. The second mounting position 103 is connected to the outside in the fourth state. The housing assembly 100 switches between the third and fourth states through the movement of the second cover 130 relative to the second base 140. The film application device 10 can apply film using the second protective film assembly 13 in the fourth state. Understandably, the housing assembly 100 is simultaneously in one of the first and second states, and also in one of the third and fourth states.

[0087] The first substrate 110 is connected to the second substrate 140. A first opening 101 is located on the side of the first substrate 110 opposite to the second substrate 140, and a second opening 108 is located on the side of the second substrate 140 opposite to the first substrate 110. This allows the film applicator 11 to flip the housing assembly 100 as needed to apply film using either the first protective film assembly 12 or the second protective film assembly 13. The first substrate 110 can be detachably connected to the second substrate 140, allowing the film applicator 10 to disassemble the housing assembly 100 into two parts, each containing a protective film assembly for one application.

[0088] In some embodiments, the housing assembly 100 may include at least one snap-fit ​​member 150. Both the first base 110 and the second base 140 are provided with snap-fit ​​portions 160 adapted to the snap-fit ​​member 150, and the snap-fit ​​portions 160 are disposed on opposite surfaces of the first base 110 and the second base 140. The snap-fit ​​member 150 can snap onto the snap-fit ​​portion 160, and the first base 110 and the second base 140 can each snap onto the same snap-fit ​​member 150 using the snap-fit ​​portion 160, thereby achieving a detachable connection between the first base 110 and the second base 140.

[0089] The snap-fit ​​portion 160 can be disposed on the edges of the first base 110 and the second base 140, for example, on the edges at both ends. The snap-fit ​​portion 160 can be a slot, and the snap-fit ​​member 150 can have a buckle adapted to the slot of the first base 110 and the second base 140. The snap-fit ​​member 150 can be inserted into the slot of the first base 110 and the second base 140 and snap-fit ​​with them. The surface of the first base 110 with the snap-fit ​​portion 160 can be in contact with the surface of the second base 140 with the snap-fit ​​portion 160.

[0090] In other embodiments, the first base 110 and the second base 140 can also be detachably connected in other ways, such as by sliding snap-fit. In this embodiment, the structures of the first base 110 and the second base 140 are basically the same, the structures of the first cover 120 and the second cover 130 are basically the same, and the mating structure of the first base 110 and the first cover 120 is also basically the same as the mating structure of the second base 140 and the second cover 130. Therefore, the following description will only take the first base 110 and the first cover 120 as an example.

[0091] Please see Figures 13 to 15 , Figure 13 yes Figure 10 A three-dimensional structural diagram of the film applicator in the second state in the embodiment. Figure 14 yes Figure 13 The diagram shown is a partial structural schematic of the film applicator. Figure 15 yes Figure 13 A partially exploded view of the film applicator in the embodiment.

[0092] In some embodiments, the first cover 120 is movably connected to the first base 110. The first base 110 may have a stop portion 111, and the first cover 120 may have a limiting portion 1201. In a first state, the stop portion 111 and the limiting portion 1201 are spaced apart. In a second state, the stop portion 111 contacts and limits the limiting portion 1201, thus maintaining communication between the first opening 101 and the outside.

[0093] The stop portion 111 can be a through hole or a blind hole, and the limiting portion 1201 can be a protrusion adapted to the stop portion 111. When the first cover 120 moves relative to the first base 110 to a preset position, the first opening 101 communicates with the outside. At this time, the limiting portion 1201 will move to a position corresponding to the stop portion 111 and engage with the stop portion 111 to limit the movement of the first cover 120 relative to the first base 110, thus keeping the first opening 101 in communication with the outside.

[0094] When the first cover 120 is subjected to an external force other than gravity and the internal force of the film application device 10, such as pressure from the user, the limiting part 1201 will disengage from the stop part 111 under the action of the external force, so that the first cover 120 can move relative to the first base 110 again, switching from the second state to the first state. The magnitude of the force required for the limiting part 1201 to disengage from the stop part 111 is affected by the shapes of the limiting part 1201 and the stop part 111. The limiting part 1201 can be designed with an arc-shaped surface; for example, the limiting part 1201 can be a hemispherical protrusion, so that the limiting part 1201 can disengage from the stop part 111 without excessive external force.

[0095] In other embodiments, the stop portion 111 and the limiting portion 1201 can also be other structures that can achieve contact limiting. For example, the stop portion 111 can be a protrusion, and the limiting portion 1201 can be a groove, the groove wall of which can be an arc surface.

[0096] In some embodiments, a limiting track 112 may be provided on the first base 110. The limiting track 112 and the stop portion 111 are disposed on the same surface of the first base 110, and the stop portion 111 and the limiting track 112 are spaced apart. In a first state, the limiting portion 1201 is engaged in the limiting track 112. In a second state, the limiting portion 1201 and the stop portion 111 are engaged and limited. During the switching process between the first state and the second state of the housing assembly 100, the limiting track 112 is used to limit the movement trajectory of the limiting portion 1201.

[0097] Taking the limiting part 1201 as a protrusion as an example, the limiting track 112 can be a strip-shaped groove provided on the first base 110. During the movement of the first cover 120 relative to the first base 110, the direction of movement of the limiting part 1201 can be set to the extension direction of the limiting track 112. When the housing assembly 100 switches from the first state to the second state, the limiting part 1201 can disengage from the limiting track 112 and engage with the stop part 111. When the limiting part 1201 is disengaged from the stop part 111 and enters the limiting track 112 by external force, the limiting part 1201 can return to its position in the first state along the limiting track 112. The limiting track 112 can limit the movement trajectory of the limiting part 1201 during its movement to prevent the limiting part 1201 from deviating from the preset movement trajectory.

[0098] In other embodiments, the limiting portion 1201 and the limiting track 112 are not limited to the above structure. For example, the limiting portion 1201 can be a groove, and the limiting track 112 can be a strip-shaped protrusion adapted to the limiting portion 1201.

[0099] The first cover 120 can be hinged to the first base 110. In the second state, the limiting part 1201 engages with the stop part 111, allowing the first cover 120 to be maintained at a preset angle relative to the first base 110, while the first opening 101 remains in communication with the outside. Please refer to the above text. Figure 16 and Figure 17 , Figure 16 yes Figure 13 A partial cross-sectional view of the film applicator in the first state in the embodiment. Figure 17 yes Figure 13 A partial cross-sectional view of the film applicator in the second state in the embodiment.

[0100] The first cover 120 can rotate relative to the first base 110 to switch the housing assembly 100 between a first state and a second state. Optionally, in the first state, the limiting portion 1201 is located at the end of the limiting track 112 away from the stop portion 111. In the second state, the limiting portion 1201 is separated from the limiting track 112 and engaged with the stop portion 111. The limiting track 112 is spaced apart from the stop portion 111, so that when the limiting portion 1201 is engaged with the stop portion 111, the wall between the stop portion 111 and the limiting track 112 will prevent the limiting portion 1201 from entering the limiting track 112.

[0101] When the first cover 120 rotates relative to the first base 110 under the action of an external force, the limiting part 1201 can be subjected to the external force to cross the wall between the limiting part 1201 and the limiting track 112. The limiting track 112 can be an arc-shaped strip track. In other embodiments, the limiting part 1201 may also be located at other positions on the limiting track 112 in the first state, such as the middle of the limiting track 112.

[0102] In some application scenarios, the first cover 120 can rotate relative to the first base 110 to a preset position so that the housing assembly 100 switches from the first state to the second state, and the first opening 101 communicates with the outside. At this time, the limiting part 1201 will engage with the stopping part 111 so that the first cover 120 is kept at a preset angle relative to the first base 110, and the first opening 101 is kept in communication with the outside. Thus, the film applicator 10 can be conveniently used to install the first protective film assembly 12 or to apply film without the user having to support the first cover 120 to prevent it from closing.

[0103] In other embodiments, the first cover 120 may also be movably connected to the first base 110 through other connection methods. For example, the first cover 120 may be slidably connected to the first base 110. The cooperation structure between the limiting part 1201 and the stop part 111, as well as the cooperation structure between the limiting part 1201 and the limiting track 112, are also applicable to other embodiments.

[0104] Understandably, the limiting design applied to the first base 110 and the first cover 120 is also applicable to the second base 140 and the second cover 130. In other words, the second cover 130 may also be provided with a limiting part 1201, and the second base 140 may also be provided with a stop part 111 and a limiting track 112, which will not be elaborated further.

[0105] In the above embodiments, the housing assembly 100 includes a base and a cover. It should be noted that in other embodiments of this application, the housing assembly 100 may also be designed with other structures. For example, the housing assembly 100 may only include the first base 110, without including the first cover 120, and the first opening 101 may remain in communication with the outside.
