[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0028] With the development of technology, more and more electronic equipment products appear in people's work, social or entertainment, and have become an indispensable part of people's lives. In order to prevent the screens of electronic devices from being damaged by external factors, many people choose to apply film on the screens of electronic devices.

[0029] With the development of technology, more and more electronic equipment products appear in people's work, social or entertainment, and have become an indispensable part of people's lives. In order to prevent the screens of electronic devices from being damaged by external factors, many people choose to apply film on the screens of electronic devices.

[0030] At present, in order to avoid interference of dust in the air on the film sticking process, users usually place the electronic device in the shell of the film applicator for film sticking. However, when the user installs the electronic device, protective film and other components inside the shell of the film applicator and closes the shell, the user cannot observe the condition inside the film applicator during the film sticking process, and cannot judge the progress of the film sticking, nor can he confirm whether the film sticking of the electronic device is completed. This may not only cause the user to open the film applicator and take out the mobile phone before the film sticking is completed, resulting in the failure of the film sticking, but also may cause the user to wait too long for the film sticking.

[0031] Based on the above questions, please refer to Figure 1 The present invention provides a film sticking device 1, which can be used to stick a film to an electronic device 2. The film sticking device 1 provided in the present invention can include: a film sticking device 10 and a protective film 20, and the protective film 20 can be installed in the film sticking device 10.

[0032] For details, please also refer to Figure 1 and Figure 2 The film applicator 10 may include a first shell 110 and a second shell 120. The second shell 120 can be covered with the first shell 110 to form a relatively closed space inside the film applicator 10. When the first shell 110 and the second shell 120 are covered, an installation space 130 for installing the electronic device 2 and the protective film 20 can be formed inside. After the user installs the electronic device 2 and the protective film 20 in the installation space 130, by covering the first shell 110 and the second shell 120, the influence of dust in the external environment on the film of the electronic device 2 can be avoided.

[0033] It should be noted that the embodiment of the present application does not limit the specific location where the installation space 130 is formed. For example, in one embodiment, the installation space 130 can be formed in the first shell 110. In other embodiments, the installation space 130 can also be formed in the second shell 120. In still other embodiments, a portion of the installation space 130 is formed in the first shell 110, and another portion is formed in the second shell 120. For ease of description, the following description will take the installation space 130 formed in the first shell 110 as an example.

[0034] Furthermore, in this embodiment, the first shell 110 may include a base 111 and a first fixing member 112 , and the first fixing member 112 is connected to the base 111 .

[0035] The installation space 130 is formed in the first fixing member 112. The embodiment of the present application does not limit the specific form of the installation space 130. For example, the installation space 130 can be a hole or a groove on the first fixing member 112. For the convenience of explanation, the following description will take the structure of the installation space 130 as an example. It can be understood that the size of the first fixing member 112 can be slightly larger than the size of the electronic device 2 to form the installation space 130. When the electronic device 2 is installed in the installation space 130, the displacement will be restricted to facilitate the subsequent film application.

[0036] In addition, the embodiment of the present application does not limit the specific structure of the base 111 and the first fixing member 112. For example, a square structure can be set to match the structure of the electronic device 2. In some other embodiments, the structure of the base 111 and the first fixing member 112 can also be set according to user preferences. For example, the base 111 and the first fixing member 112 can be set to a circle or other irregular shapes.

[0037] The embodiments of the present application also do not limit the connection method between the base 111 and the first fixing member 112. For example, in one embodiment, the base 111 can be detachably connected to the first fixing member 112, such as by snap-fitting, bonding, or interference fitting, etc. This makes it easy for the user to disassemble the base 111 from the first fixing member 112. When encountering electronic devices 2 of different sizes, the user only needs to replace the first fixing member 112 and select the first fixing member 112 of matching size to apply a film to the electronic device 2. This can improve the applicability of the film applying device 1 and reduce the user's usage cost.

[0038] In another embodiment, the base 111 may be integrally formed with the first fixing member 112, for example, by integral injection molding, etc. This may improve the structural strength and consistency of the first shell 110 and prevent the first fixing member 112 from detaching due to a collision of the first shell 110.

[0039] Furthermore, in one embodiment, the first housing 110 may also be provided with an avoidance area 113 for avoiding the camera of the electronic device 2. The embodiment of the present application does not limit the specific form of the avoidance area 113, for example, it may be a groove, or it may be a through hole, etc., and it may be specifically set according to the actual situation. When the avoidance area 113 is a groove structure, the avoidance area 113 may be only set on the first fixing member 112; when the avoidance area 113 is a through hole structure, the avoidance area 113 may be set on the base 111 and the first fixing member 112 at the same time, so that the user can more intuitively see whether the electronic device 2 is accurately installed in the installation space 130. Therefore, in this embodiment, the avoidance area 113 also has the function of detecting whether the user has accurately installed the electronic device 2.

[0040] For further information, see Figure 3 In this embodiment, the first fixing member 112 may be provided with a first connecting portion 112a, and the first connecting portion 112a may cooperate with the second shell 120. When the first shell 110 and the second shell 120 are covered, the first connecting portion 112a may be used to ensure that the first shell 110 and the second shell 120 are snapped into place to avoid displacement of the first shell 110 and the second shell 120 after they are covered, thereby affecting the film sticking operation.

[0041] Please continue reading Figure 2 In this embodiment, the second shell 120 may include an upper cover 122 and a second fixing member 123 , and the second fixing member 123 may be connected to the upper cover 122 .

[0042] The embodiment of the present application also does not limit the specific structure and connection method of the upper cover 122 and the second fixing member 123. For example, the relevant description of the base 111 and the first fixing member 112 can be referred to, and no further details are given here.

[0043] In this embodiment, a fixed space 160 can also be formed between the first fixing member 112 and the second fixing member 123. The fixed space 160 can be used to fix the electronic device 2. The fixed space 160 can be located inside the installation space 130. The embodiment of the present application does not limit the specific position of the fixed space 160. For example, in one embodiment, the fixed space 160 can be formed in the first fixing member 112. In another embodiment, the fixed space 160 can also be formed in the second fixing member 123. In yet another embodiment, the fixed space 160 can also be formed in the first fixing member 112 and the second fixing member 123 at the same time. The specific setting can be made according to actual conditions.

[0044] It should be noted that, in this embodiment, the upper cover 122 needs to match the base 111 , and the second fixing member 123 needs to match the first fixing member 112 , so that when the first shell 110 and the second shell 120 are covered, a relatively closed space can be formed.

[0045] In this embodiment, the observation window 121 may be a first observation portion provided on the upper cover 122 and a second observation portion of the first fixing member 112. For example, in one embodiment, the observation window 121 may be provided through the upper cover 122 and the first fixing member 112. It should be noted that the above-mentioned observation window 121 may be understood as a window for observing the interior of the first housing 110, and a glass sheet or a transparent plastic sheet may be provided at the observation window 121 to prevent dust from entering the interior of the first housing 110 from the observation window 121. For another example, in another embodiment, the observation window 121 may be a transparent structure, and the observation window 121 may be integrally formed with the upper cover 122 and the first fixing member 112. The specific configuration may be based on actual conditions and is not limited here.

[0046] It should be noted that the embodiment of the present application does not limit the specific structure of the observation window 121. For example, it can be a strip-shaped window or an elliptical window, etc., and can be specifically set according to actual conditions.

[0047] In this example, see Figure 4 The second fixing member 123 is also provided with a second connecting portion 123a, and the second connecting portion 123a can cooperate with the first connecting portion 112a. When the second shell 120 is covered on the first shell 110, the second connecting portion 123a can be locked with the first connecting portion 112a, so that the first shell 110 and the second shell 120 are relatively fixed to ensure the normal film application.

[0048] It should be noted that the embodiments of the present application do not limit the specific structures of the first connecting portion 112a and the second connecting portion 123a. For example, in the present embodiment, one of the first connecting portion 112a and the second connecting portion 123a can be a protrusion and the other can be a groove. When the second shell 120 is covered on the first shell 110, the protrusion can be embedded in the groove to achieve relative fixation of the first shell 110 and the second shell 120.

[0049] For the sake of convenience, the following description will take the first connection portion 112a as a groove and the second connection portion 123a as a protrusion as an example. Figure 3 and Figure 4The groove can be located on the groove wall of the groove forming the installation space 130, that is, at least one groove wall of the groove of the installation space 130 can be set to have a defective structure, the groove can be formed at the above-mentioned defect, the protrusion structure can match the above-mentioned defective structure, and when the second shell 120 is covered on the first shell 110, the protrusion can be embedded in the groove.

[0050] For further information, please refer to Figure 4 In one embodiment, the second fixing member 123 is further provided with an elastic portion 123b. The elastic portion 123b can be arranged on the surface of the second fixing member 123 facing the first fixing member 112, and the elastic portion 123b can be located in the area where the installation space 130 is located. The elastic portion 123b can be used to press against the electronic device 2 installed in the installation space 130 to facilitate the exhaust operation after the film is applied to the electronic device 2.

[0051] It should be noted that the embodiment of the present application does not limit the specific structure of the elastic portion 123b. For example, it can be a strip-shaped elastic portion 123b or an elliptical elastic portion 123b, etc., and can be specifically configured according to actual conditions.

[0052] In addition, the embodiment of the present application does not limit the specific location of the elastic portion 123b. For example, in one embodiment, the second fixing member 123 may have a length direction, such as Figure 4 In the A direction, the elastic part 123b can be arranged at the end of the length direction of the second fixing part, so that the electronic device 2 can start to exhaust from one end when exhausting, which is conducive to ensuring the exhaust effect. It should be noted that in other embodiments, the elastic part 123b can also be arranged in the middle of the length direction of the second fixing part, so that the electronic device 2 can exhaust from the middle to both ends at the same time when exhausting, which is conducive to improving the exhaust efficiency. The specific arrangement can be made according to actual conditions.

[0053] For further information, please refer again to Figure 2-Figure 4 In one embodiment, the film applicator 10 may be provided with a positioning portion 140 for positioning the protective film 20. It should be noted that the embodiment of the present application does not limit the specific position of the positioning portion 140. For example, in one embodiment, the positioning portion 140 may be provided on the first shell 110. In another embodiment, the positioning portion 140 may be provided on the second shell 120. In yet another embodiment, both the first shell 110 and the second shell 120 may be provided with the positioning portion 140. The specific setting may be based on actual conditions.

[0054] The embodiments of the present application do not limit the specific structure of the first shell 110 and the second shell 120. For the sake of convenience, the following description will take the example that both the first shell 110 and the second shell 120 are provided with a positioning portion 140, wherein the positioning portion 140 can be a positioning hole or a positioning pin. Specifically, one of the first fixing member 112 and the second fixing member 123 can be provided with a positioning pin, and the other can be provided with a positioning hole. The positions of the positioning pin and the positioning hole can be set correspondingly, that is, the positioning pin can be embedded in the positioning hole, and the protective film 20 can be sleeved in the positioning pin, that is, the positioning pin can be passed through the protective film 20 and embedded in the positioning hole to achieve the positioning of the protective film 20.

[0055] It should be noted that the embodiments of the present application do not limit the number of positioning pins and positioning holes. For example, the positioning pins can be set to 2 or 3 or 4, etc. The number of positioning holes is consistent with the number of positioning pins. The setting of positioning pins and positioning holes can further strengthen the connection between the first fixing member 112 and the second fixing member 123.

[0056] For further information, please refer again to Figure 1 and Figure 2 In the present embodiment, the film applicator 10 may further be provided with a notch 150, which is connected to the installation space 130, and the notch 150 can be used by the user to pull out the protective film 20. It should be noted that the embodiment of the present application does not limit the specific position of the notch 150. For example, in one embodiment, the notch 150 may be provided in the first shell 110, specifically in the first fixing member 112. In another embodiment, the notch 150 may be provided in the second shell 120, specifically in the second fixing member 123. In yet another embodiment, the notch 150 may also be provided in both the first fixing member 112 and the second fixing member 123, and may be provided specifically according to actual conditions.

[0057] Please also see Figure 2-Figure 5 The protective film 20 can be adapted to the installation space 130 so that the protective film 20 can cover the screen of the electronic device 2. The protective film 20 can be provided with a mounting hole 211, and the mounting hole 211 can be sleeved in the positioning pin.

[0058] For details, please refer to Figure 5In this embodiment, the protective film 20 may include: a positioning layer 210, a protective layer 220, a release layer 230 and a drawstring 240. The positioning layer 210 may be used to position the protective film 20 on the shell, the mounting hole 211 may be provided in the positioning layer 210, the protective film 20 may be used to be attached to the electronic device 2, the protective layer 220 may be provided between the positioning layer 210 and the release layer 230, the release layer 230 may be used to protect the protective layer 220, the drawstring 240 may be connected to the release layer 230, and used to drive the release layer 230 to separate from the protective layer 220, so as to facilitate the protective layer 220 to be attached to the electronic device 2.

[0059] Furthermore, in one embodiment, the protective layer 220 and the release layer 230 can be bonded together by an AB glue layer 250 (two liquids mixed and hardened). This can ensure that before the protective film 20 is used, the release layer 230 can be tightly bonded to the protective layer 220, thereby providing good protection for the protective layer 220. Similarly, the positioning layer 210 and the protective layer 220 can also be bonded together by the AB glue layer 250.

[0060] The following is a method for using the film sticking device 1 provided in an embodiment of the present application:
