Description

Technical Field

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

[0002] To protect their phone screens, users often apply screen protectors. There are several ways to apply screen protectors to phone screens. One method involves fixing the phone to a base, then placing a cover with the protective film on the base, removing the release liner, and pressing the film onto the screen. Another method involves placing the protective film inside a cover, then placing the cover on the phone, removing the release liner, and pressing the phone onto the film. Since car screens are fixed to the vehicle body and cannot be moved, the first method is not suitable. As for the second method, where the applicator is enlarged and directly applied to the car screen, the process involves pulling the release liner with one hand and pressing the applicator with the other. Because car screens are much larger than phone screens, pressing with one hand makes it difficult to ensure a stable fit between the applicator and the screen. The applicator is easily deflected or shifted due to the pulling force, making application difficult and compromising the effectiveness of the film. Utility Model Content

[0021] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this application are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0022] Please combine Figures 1 to 6 The following is an exemplary description of the film applicator 10 provided in this application. The film applicator 10 provided in this application is used in conjunction with a film applicator assembly to apply a film to a vehicle display screen 20. The film applicator assembly (not shown) includes a positioning film, a protective film, a release film, and a pull strip stacked in sequence. One end of the pull strip is connected to the release film, and the other end protrudes from the release film to form a pull-out portion for manual operation.

[0023] Please refer to Figure 1 The film applicator 10 includes a carrier plate 11, a film fixing member 12, a limiting assembly 13, and a fastening assembly. The carrier plate 11 has a receiving cavity 101, and a pull-out opening 103 communicating with the receiving cavity 101 is provided on one side of the carrier plate 11. The film fixing member 12 is disposed in the receiving cavity 101 and is used to cooperate with the positioning film to fix the protective film. The limiting assembly 13 defines an receiving groove 102 within the receiving cavity 101 that cooperates with the display screen 20.

[0024] The fastening component is used to restrict the display 20 from leaving the receiving slot 102 when the display 20 is placed into the receiving slot 102.

[0025] When the positioning film and the fixed film component 12 are engaged, the pull strip is located on the side of the protective film facing the receiving groove 102 and can extend from the receiving cavity 101 through the pull-out port 103. When the display screen 20 is placed in the receiving groove 102, the pull strip moves away from the pull-out port 103 under external force, and peels the release film off the protective film, and the protective film is attached to the display screen 20.

[0026] It is understood that the receiving cavity 101 is an open cavity. For ease of description, the opening of the receiving cavity 101 faces upward, and the pull-out port 103 is located on one side of the receiving cavity 101. The positioning membrane 12 can be disposed at the bottom of the receiving cavity 101 or on the peripheral wall of the receiving cavity 101, and it cooperates with the positioning membrane. Figure 2In the structure shown, the fixing member 12 is a columnar shape that connects to the bottom of the cavity and extends upward, and is fixed by cooperating with the positioning hole on the positioning membrane. In other embodiments, the positioning membrane may also be a hook-shaped shape that connects to the periphery of the receiving cavity 101 and extends inward, and is fixed by hooking the positioning hole on the positioning membrane.

[0027] The limiting component 13 is fixed to the bottom or peripheral wall of the receiving cavity 101 and defines a receiving groove 102 that mates with the display screen 20. It can be understood that the fixing member 12 avoids the receiving groove 102 to prevent obstruction of the display screen 20 from being placed into the receiving groove 102. In the illustrated structure, the fixing member 12 is located on the outer peripheral side of the receiving groove 102.

[0028] A fastening component is disposed in the receiving groove to prevent the display screen 20 from moving upward and leaving the receiving groove 102 when the display screen 20 is placed into the receiving groove 102. In this embodiment, when the display screen 20 is placed into the receiving groove 102, the fastening component fastens to the back of the display screen 20 or the vehicle body, thereby achieving the fastening of the film applicator 10.

[0029] During film application, the positioning film of the film application assembly is first fixed to the fixing film component 12 of the film application device, thus achieving relative fixation between the film application assembly and the film applicator 10, and positioning of the protective film. At this time, the release film and the pull strip are located on the upper side of the protective film. Then, the opening of the film applicator 10 is aligned with the display screen 20 and inserted into the display screen 20, so that the display screen 20 is placed in the receiving groove 102. At this time, the fastening assembly fastens the film applicator 10 to the display screen 20. The user grasps the pull part and pulls the pull strip out from the pull opening 103, and the release film is pulled away, exposing the protective film facing the side of the display screen 20. Finally, the protective film is pressed onto the display screen 20, completing the film application to the display screen 20.

[0030] In this embodiment, by setting a fastening component, the film applicator 10 is fastened to the display screen 20, which can avoid the situation of incorrect film application or film application failure caused by relative movement or deflection between the film applicator 10 and the display screen 20 during the film application operation.

[0031] In this embodiment, the film application assembly can adopt the existing film application assembly structure, which will not be described in detail here.

[0032] Please refer to Figure 3 , Figure 5 and Figure 6 In this embodiment of the application, the fastening component includes a first fastening member 141 and a second fastening member 142 disposed on opposite sides of the receiving groove 102. The first fastening member 141 is used to fasten the display screen 20 when the display screen 20 is placed in the receiving groove 102, and the second fastening member 142 is used to fasten the air outlet 30 adjacent to the display screen 20 when the display screen 20 is placed in the receiving groove 102.

[0033] The film applicator 10 provided in this embodiment is suitable for a vehicle rear seat display screen 20. The rear seat display screen 20 is located on the armrest box and above the air vent 30. The rear seat display screen 20 has a chamfered transition, and a small recess is formed between the corner of its side and back and the armrest box. The first fastening member 141 cooperates with this recessed structure to achieve the effect of fastening and securing one side of the film applicator 10. For the fastening of the other side of the film applicator 10, the same method of fastening at the corresponding recess can be used. However, the size of this recess is smaller. In order to further improve the fastening effect, this embodiment utilizes the structural design of the display screen 20 close to the air vent 30 to set the second fastening member 142 to fasten and secure with the air vent 30. Compared with the aforementioned recessed structure, the air vent 30 has a larger space to accommodate the second fastening member 142, allowing the second fastening member 142 to be inserted with a larger fastening part, thereby increasing the difficulty of the second fastening member 142 leaving the air vent 30, and thus improving the fastening of the film applicator 10 and the display screen 20.

[0034] It is understood that the first fastening member 141 and the second fastening member 142 have a certain degree of elasticity, so that they can undergo elastic deformation during the process of the film applicator 10 being placed into the display screen 20, and reset and fasten when they reach the aforementioned recess and air outlet 30 positions. After the film is applied, the first fastening member 141 can be disengaged from the recess by applying external force to one side of the first fastening member 141 of the film applicator 10, thereby separating the film applicator 10 from the display screen 20.

[0035] In another embodiment of this application, please refer to Figure 2 The first fastener 141 and the second fastener 142 are located on both sides of the length direction of the receiving groove, and the pull-out opening 103 is located on one side of the width direction of the receiving groove.

[0036] Referring to the diagram, multiple first fasteners 141 are spaced apart on the same side along the length of the applicator 10, and multiple second fasteners 142 are spaced apart on the other side along the length of the applicator 10. This achieves multi-point fastening. Compared to placing the first and second fasteners 141 and 142 on both sides of the applicator 10's width, this arrangement improves the fastening effect of the applicator 10. This arrangement also avoids obstructing the movement path of the pull strip. Placing the pull-out opening 103 on one side of the receiving groove's width reduces the resistance to pulling and tearing the film. The opening of the pull-out opening 103 reduces the structural strength of the side where it is located, making it prone to deformation. Placing the pull-out opening 103 on one side of the width, while placing the fastening components on both sides of the length, allows for the realization of their respective functions without interference, resulting in a reasonable arrangement.

[0037] In another embodiment of this application, please refer to Figure 2 and Figure 4The limiting component 13 includes a height limiting member 131 protruding from the bottom of the cavity of the receiving groove and a horizontal limiting member disposed on the four sides of the display screen 20. The height limiting member 131 and the horizontal limiting member surround and form the receiving groove 102.

[0038] Multiple height limiting members 131 are distributed within the receiving cavity 101. Each height limiting member 131 is set at the same height, and its upper surface forms the bottom of the receiving groove 102. Multiple horizontal limiting members are also present, forming the peripheral walls of the receiving groove 102.

[0039] The height limiting component 131 restricts the insertion depth of the display screen 20. Please refer to... Figure 3 , Figure 5 or Figure 6 A film cavity 105 is formed between the display screen 20 and the carrier plate 11 for inserting the film application assembly. In other words, the height limiting member 131 ensures the storage space for the film application assembly.

[0040] There are multiple height limiting components 131. Figure 2 In the structure shown, height limiting members 131 are provided on both sides of the length of the receiving cavity 101 and on the side opposite to the pull-out opening 103.

[0041] In another embodiment of this application, please refer to Figure 2 and Figure 4 The horizontal limiting member includes a first limiting member 132 provided on both sides of the length direction of the receiving cavity 101 and a second limiting member 133 provided on both sides of the width direction of the receiving cavity 101. The second limiting member 133 has a limiting part 1331 for limiting the horizontal movement of the display screen 20 and a guiding part 1332 for guiding the display screen 20 into the receiving groove 102.

[0042] The first limiting member 132 is used to define the boundary of the long side of the receiving groove 102, and the second limiting member 133 is used to define the boundary of the wide side of the receiving groove 102.

[0043] The second limiting member 133 has a limiting part 1331 and a guiding part 1332. The limiting part 1331 is used to limit the width direction boundary of the receiving groove 102, and the guiding part 1332 is used to guide the display screen 20 into the receiving groove 102 to improve the convenience of operation.

[0044] There are multiple first limiting members 132, arranged in two rows on both sides of the length of the receiving cavity 101, and the space between the two rows of first limiting members 132 is the width space of the receiving groove 102.

[0045] For preferred options, please refer to [the provided text]. Figure 2 and Figure 4 The number of height limiting members 131 and the first limiting member 132 on the same side are the same, and they are connected as a whole. This arrangement simplifies the structure and reduces production costs. Figure 2 In the structure shown, there are two height limiting members 131 and two first limiting members 132 on the same side. In other embodiments, those skilled in the art may also set the number to one, three, five, etc., and this is not a unique limitation. One height limiting member 131 and one first limiting member 132 are connected to form an integral structure.

[0046] The receiving cavity 101 and the pull-out opening 103 are each provided with a height limiting member 131 and a second limiting member 133. The number of height limiting members 131 and the second limiting member 133 are the same, and they are integrally set. The side where the pull-out opening 103 is located does not have a height limiting member 131 to prevent the pull bar from moving. The second limiting member 133 is set on the cavity wall of the receiving cavity 101.

[0047] In another embodiment of this application, please refer to Figure 2 and Figure 4 There are multiple first fastening parts 141, which are integrally set with the first limiting parts 132 on the same side; there are multiple second fastening parts 142, which are integrally set with the first limiting parts 132 on the other side.

[0048] Figure 2 In the structure shown, there are two first fastening members 141, which are integrally set with the first limiting member 132 on the same side. This arrangement simplifies the structure and design and reduces production costs. Similarly, there are two second fastening members 142, which are integrally set with the first limiting member 132 on the same side. This arrangement simplifies the structure and design and reduces production costs.

[0049] Combined with the height limiting member 131, a height limiting member 131, a first limiting member 132 and a first fastening member 141 on the same side are sequentially connected to form a whole, and a height limiting member 131, a first limiting member 132 and a second fastening member 142 on the same side are sequentially connected to form a whole.

[0050] It should be noted that those skilled in the art may integrate only a portion of the first fastening member 141, the second fastening member 142, or a portion of the height limiting member 131 with the first limiting member 132, while other portions of the first fastening member 141 or the height limiting member 131 may be set separately. Alternatively, a separate first limiting member 132 may be set separately; this is not the only option.

[0051] In another embodiment of this application, the carrier plate 11 has a through hole 104 at the bottom of the receiving cavity 101 to allow a person to press the protective film. The through hole 104 is provided so that a person can directly apply the film-applying assembly to press the protective film onto the display screen 20.

[0052] Preferably, the through hole 104 is elongated to facilitate the film application process, allowing the user to move along its length to gradually press the protective film onto the display screen 20.

[0053] Figure 1 In the structure shown, the through hole 104 is an elongated hole that extends along the diagonal of the receiving cavity 101. First, this arrangement can meet the operational requirements of gradually pressing the protective film onto the display screen 20 from the length direction. In addition, it can improve the visual aesthetic effect. Finally, it can also reduce the amount of material used and reduce costs.

[0054] Figure 1 In the structure shown, there are multiple through holes 104, and their extending directions are parallel. Those skilled in the art can set the number, size, and position of the through holes 104 according to actual needs, and no unique limitation is made here.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the protection scope of this application.
