Description

Technical Field

[0001] This application relates to the field of tempered glass film positioning cleanroom technology, and more particularly to an ultra-thin tempered glass film positioning cleanroom. Background Technology

[0002] The tempered glass screen protector positioning dust-free chamber is a device used to assist in the application of tempered glass screen protectors to mobile phones. Its main structure includes a positioning component for fixing the position of the mobile phone and a dust-free cover for isolating dust in the air, providing users with a relatively clean and stable environment for applying the screen protector, thereby improving the accuracy and success rate of the application.

[0003] In existing technologies, tempered glass film positioning cleanrooms mostly adopt a box-like structure. The chamber is generally made of plastic, acrylic, or composite materials to achieve a balance between structural strength and lightweight. These devices are usually designed with structural dimensions and portability in mind, often opting for a small chamber size. Some products even employ foldable or detachable designs, further reducing their size when not in use to minimize packaging material costs.

[0004] However, frequent folding can cause minor deformations in structural components and loosening of connecting parts, thereby weakening the structural stability of the device. This can lead to problems such as unstable phone placement or misalignment of the positioning device, resulting in poor adhesion of the tempered glass screen protector. The detachable structure increases user operation steps and complicates the overall product structure. Therefore, a dust-free tempered glass screen protector enclosure that reduces volume while ensuring device stability is needed to solve these problems. Utility Model Content

[0005] In view of this, it is necessary to provide a thin and structurally stable tempered glass positioning dust-free chamber to solve the above problems.

[0006] An embodiment of this application provides an ultra-thin tempered glass film positioning dust-free compartment, including a compartment body and a film bonding assembly. The compartment body is integrally formed and has an inner cavity for placing a mobile phone.

[0007] The diaphragm bonding assembly includes a pressing component and a positioning component. The positioning component is located at one end of the chamber and is rotatably connected to the chamber. The pressing component is located at the other end of the chamber and can move along the length of the chamber to press the diaphragm.

[0008] The chamber body is further provided with a first groove and a second groove at its opposite ends. The pressing component is located in the first groove, and the positioning component is located in the second groove, so as to reduce the volume of the cleanroom.

[0009] In at least one embodiment of this application, the second groove includes a receiving cavity and a rotating cavity that are in communication with each other, and the receiving cavity and the rotating cavity are arranged side by side;

[0010] The positioning element extends into the rotating cavity and fits against the side wall of the rotating cavity. When the positioning element is rotated, the end of the positioning element away from the rotating cavity enters the receiving cavity.

[0011] In at least one embodiment of this application, the inner wall of the rotating cavity extends along the rotation direction of the positioning member to form a limiting portion. The positioning member includes a positioning block and a rotating shaft disposed on the positioning block. The limiting portion is disposed above the rotating shaft to prevent the rotating shaft from disengaging from the rotating cavity.

[0012] In at least one embodiment of this application, the positioning block includes a first surface, a second surface, and a third surface arranged sequentially. When the positioning block enters the receiving cavity, the first surface fits against the bottom of the second groove, and the limiting portion fits against the rotating shaft.

[0013] In at least one embodiment of this application, the chamber body extends outward on both sides along its length direction to form sliding portions, and one end of the chamber body extends outward to enclose the chamber body to form the first groove;

[0014] The pressing component includes a pressing part and a limiting post disposed on the pressing part. When the diaphragm is applied, the pressing part moves and abuts against the diaphragm, and the limiting post abuts against the sliding part to move along the setting direction of the sliding part.

[0015] In at least one embodiment of this application, the sliding portion has an opening at one end near the positioning member, the opening being used to remove the pressing member.

[0016] In at least one embodiment of this application, when viewed along a height direction perpendicular to the chamber body, when the pressing member is disposed in the first groove and the positioning member is disposed in the second groove, neither the pressing member nor the positioning member is higher than the chamber body.

[0017] In at least one embodiment of this application, the housing further includes a padding layer, which is arranged around the side wall of the inner cavity. When the film is applied, the mobile phone abuts against the padding layer, and a gap is formed between the mobile phone and the bottom of the inner cavity.

[0018] In at least one embodiment of this application, the pad has an inclined surface along the opening direction of the inner cavity for securing the mobile phone.

[0019] In at least one embodiment of this application, the dust-free chamber has a through hole communicating with the inner cavity, and the through hole is used to push the mobile phone away from the inner cavity after the screen protector is applied.

[0020] The aforementioned ultra-thin tempered glass membrane positioning cleanroom improves overall structural strength by designing the chamber body as a one-piece molded structure, which is beneficial for enhancing the cleanliness and stability of membrane adhesion. Positioning and pressing components are respectively located in the second and first grooves at both ends of the chamber body, allowing the components to be embedded inside the chamber body when not in operation. This avoids the problems of excessive chamber thickness and irregular shape caused by the protrusion of traditional external positioning structures and pressing components. This significantly reduces the overall external thickness of the cleanroom and decreases its volume. Attached Figure Description

[0031] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0033] An embodiment of this application provides an ultra-thin tempered glass film positioning dust-free compartment, including a compartment body and a film bonding assembly. The compartment body is integrally formed and has an inner cavity for placing a mobile phone.

[0034] The diaphragm bonding assembly includes a pressing component and a positioning component. The positioning component is located at one end of the chamber and is rotatably connected to the chamber. The pressing component is located at the other end of the chamber and can move along the length of the chamber to press the diaphragm.

[0035] The chamber body is further provided with a first groove and a second groove at its opposite ends. The pressing component is located in the first groove, and the positioning component is located in the second groove, so as to reduce the volume of the cleanroom.

[0036] The aforementioned ultra-thin tempered glass membrane positioning cleanroom improves overall structural strength by designing the chamber body as a one-piece molded structure, which is beneficial for enhancing the cleanliness and stability of membrane adhesion. Positioning and pressing components are respectively located in the second and first grooves at both ends of the chamber body, allowing the components to be embedded inside the chamber body when not in operation. This avoids the problems of excessive chamber thickness and irregular shape caused by the protrusion of traditional external positioning structures and pressing components. This significantly reduces the overall external thickness of the cleanroom and decreases its volume.

[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Please see Figures 1-8 The embodiments of this application provide an ultra-thin tempered glass film positioning dust-free compartment 100, including a compartment body 10 and a film bonding assembly 20. The compartment body 10 is integrally formed and has an inner cavity 11 for placing a mobile phone.

[0039] The diaphragm bonding assembly 20 includes a pressing member 21 and a positioning member 22. The positioning member 22 is located at one end of the chamber 10 and is rotatably connected to the chamber 10. The pressing member 21 is located at the other end of the chamber 10 and can move along the length of the chamber 10 for pressing the diaphragm.

[0040] The chamber body 10 is further provided with a first groove 12 and a second groove 13 at its opposite ends. The pressing member 21 is provided in the first groove 12 and the positioning member 22 is provided in the second groove 13 to reduce the volume of the cleanroom.

[0041] Preferably, the housing 10 is a one-piece molded structure, with an internal cavity 11 for placing the mobile phone, serving as the basic support component for the entire screen protector application process. The housing 10 has a first groove 12 and a second groove 13 at each end for embedding the pressing component 21 and the positioning component 22, allowing these functional components to be completely retracted into the housing 10 when not in use, thus achieving a flat overall structure and volume compression.

[0042] Furthermore, the positioning member 22 located at one end of the chamber 10 is rotatably connected to the chamber 10. When the film application operation begins, the positioning member 22 can rotate from the stored state to the preset working position to accurately limit and guide the tempered glass film. Meanwhile, the pressing member 21 located at the other end of the chamber 10 achieves a smooth pressing process on the positioned film by sliding along the length of the chamber 10.

[0043] Specifically, the one-piece molded chamber 10 structure eliminates assembly errors, local deformations, or gaps present in traditional assembled structures, making the internal cavity 11 more precise and stable in position. The first groove 12 and the second groove 13 work in conjunction with the bonding components to achieve structural compression under functional integration. After the film application is completed, the pressing component 21 and the positioning component 22 can be stored in the grooves provided at both ends of the chamber 10, thereby avoiding the increase in thickness caused by the protrusion of the components.

[0044] In one specific embodiment, the second groove 13 includes a receiving cavity 131 and a rotating cavity 132 that are in communication with each other, and the receiving cavity 131 and the rotating cavity 132 are arranged side by side;

[0045] The positioning member 22 extends into the rotating cavity 132 and fits against the side wall of the rotating cavity 132. When the positioning member 22 is rotated, the end of the positioning member 22 away from the rotating cavity 132 enters the receiving cavity 131.

[0046] Preferably, the rotating cavity 132 serves as the bearing area of ​​the rotating shaft 222 of the positioning member 22, providing a support structure for its rotational movement; the accommodating cavity 131 serves as the storage space for the positioning member 22 in its non-working state; the two are connected and arranged side by side, ensuring that the positioning member 22 can naturally transition from the rotating state to the hidden state after rotation, achieving interference-free storage.

[0047] Furthermore, during installation, the rotating end of the positioning element 22 is inserted into the rotating cavity 132 and fits against the side wall of the cavity, allowing it to rotate with the rotating cavity 132 as a reference. The fit against the side wall ensures stability during rotation, preventing shaking or detachment; it also ensures that the positioning element 22 always rotates around a set axis, coordinating with the spatial position of the receiving cavity 131 so that the other end can accurately enter the receiving cavity 131 after rotation. This enhances the mechanical precision and repeatability of the device, helping to maintain consistent diaphragm positioning.

[0048] In one specific embodiment, the inner wall of the rotating cavity 132 extends along the rotation direction of the positioning member 22 to form a limiting part 132a. The positioning member 22 includes a positioning block 221 and a rotating shaft 222 disposed on the positioning block 221. The limiting part 132a is disposed above the rotating shaft 222 to prevent the rotating shaft 222 from leaving the rotating cavity 132.

[0049] Preferably, the limiting part 132a and the rotating cavity 132 form an integral structure, sealing the space above the rotating shaft 222 and preventing the rotating shaft 222 from being pulled out of the cavity during rotation or use. The rotating shaft 222 is integrally formed or connected to the positioning block 221, and is the fulcrum and axis for the positioning block 221 to rotate relative to the compartment 10.

[0050] In one specific embodiment, the end of the positioning block 221 away from the rotation axis is also provided on a positioning post. The positioning post has a polygonal structure, which can better fix the outer fixing layer of the diaphragm. The polygonal structure has a larger contact surface with the fixing layer of the diaphragm, which is larger than the contact area of ​​a circular positioning post, and can be better fixed.

[0051] In one specific embodiment, the positioning block 221 includes a first surface, a second surface and a third surface arranged in sequence. When the positioning block 221 enters the receiving cavity 131, the first surface is in contact with the bottom of the second groove 13, and the limiting part 132a is in contact with the rotating shaft 222.

[0052] Preferably, the first surface fits against the bottom of the groove to form a stable support surface, preventing the positioning block 221 from shaking or tilting within the receiving cavity 131. The limiting part 132a cooperates with the rotating shaft 222 to provide axial anti-dislodgement protection, preventing the positioning member 22 from becoming loose due to accidental pulling.

[0053] Furthermore, the second surface fits against the bottom of the groove to form a rotation endpoint stop, limiting the opening angle of the positioning block 221; the third surface fits against the side wall of the groove to provide lateral support, preventing the positioning element 22 from wobbling left and right during use. The two together constitute a double-sided limiting system after the positioning element 22 is unfolded, constraining its working position in both the longitudinal and lateral directions, ensuring that the diaphragm can achieve precise alignment after being fitted with the positioning element 22, and will not be misaligned or produce air bubbles due to the wobbling of the positioning element 22.

[0054] In one specific embodiment, the chamber body 10 extends outward on both sides along its length direction to form sliding portions 14, and one end of the chamber body 10 extends outward to enclose the chamber body 10 to form the first groove 12;

[0055] The pressing member 21 includes a pressing part 211 and a limiting post 212 disposed on the pressing part 211. When the film is attached, the pressing part 211 is moved and abuts against the film, and the limiting post 212 abuts against the sliding part 14 to move along the setting direction of the sliding part 14.

[0056] Preferably, track-shaped sliding parts 14 are provided on both sides of the chamber body 10, with their direction consistent with the length direction of the chamber body 10. This provides a linear guide function, ensuring that the pressing part 21 moves accurately and smoothly during the movement process; preventing the pressing part 21 from tilting, shaking, or shifting, and ensuring that the diaphragm is subjected to uniform force.

[0057] Furthermore, the limiting post 212 is nested in the sliding part 14, forming a slide rail-slider cooperation with the sliding part 14, controlling the movement of the pressing part 21 along a fixed path to ensure that the diaphragm is evenly adhered from top to bottom (or from left to right). The limiting post 212 embedded in the sliding part 14 forms a constraint channel, ensuring that the pressing part 211 can only move linearly in a set direction; the limiting structure enables operation without technical barriers, and the user can complete the adhesion by simply pushing the pressing part 21 with one hand.

[0058] In one specific embodiment, the sliding part 14 has an opening 141 at one end near the positioning member 22, and the opening 141 is used to remove the pressing member 21.

[0059] Specifically, the positioning element 22 is located at one end of the chamber 10, adjacent to the diaphragm positioning area. The sliding path of the pressing element 21 begins at the first groove 12 and ends near the end of the positioning element 22; an opening 141 is provided at the end of the sliding part 14, so that the pressing element 21 can be directly removed from this position after the diaphragm is pressed. Taking advantage of the structural continuity and the adjacency of functional areas, an exit is provided near the pressing completion position.

[0060] Furthermore, after the bonding is completed, the pressing component 21 can be reinstalled into the first groove 12, and the detachable design allows for the replacement of different pressing components 21 according to different mobile phone models that require screen protectors, thus making the device more adaptable.

[0061] In one specific embodiment, when viewed along the height direction perpendicular to the chamber body 10, when the pressing member 21 is disposed in the first groove 12 and the positioning member 22 is disposed in the second groove 13, neither the pressing member 21 nor the positioning member 22 is higher than the chamber body 10.

[0062] Specifically, both the pressing component 21 and the positioning component 22 are housed within the outline height of the chamber body 10, allowing the chamber body 10 to achieve extreme thickness compression even when housed; ensuring that the entire cleanroom device has a flat, easily transportable geometric feature. This meets the thin packaging requirements for the integrated sale of "mobile phone film + cleanroom tools"; it also meets logistics and display needs, reduces production and distribution costs, and improves product integration.

[0063] In one specific embodiment, the housing 10 further includes a padding layer 15, which is arranged around the side wall of the inner cavity 11. When the film is applied, the mobile phone abuts against the padding layer 15, and a gap is formed between the mobile phone and the bottom of the inner cavity 11.

[0064] Preferably, the padding layer 15 is fixed in a ring shape to the side wall of the inner cavity 11 of the compartment 10. The padding layer 15 surrounds the edge of the mobile phone and acts as a buffer and positioning medium between the mobile phone and the side wall of the compartment 10, which, together with the integrally formed inner cavity 11 of the compartment 10, ensures the stable placement of the mobile phone.

[0065] Furthermore, a certain gap is maintained between the mobile phone and the bottom of the inner cavity 11 to avoid direct pressure on the bottom of the mobile phone, while leaving necessary space for the movement of the pressing component 21 or the positioning component 22; this gap plays a buffering and regulating role in the pressure distribution applied during the pressing process, preventing local compression from causing bonding defects.

[0066] In one specific embodiment, the pad 15 is provided with an inclined surface 151 along the opening 141 of the inner cavity 11 for clamping the mobile phone.

[0067] Specifically, the inclined surface 151 allows the phone to smoothly enter the housing 10, and the elastic reaction force of the inclined angle gradually adheres to the padding layer 15, reducing loosening. This improves the stability of the phone within the inner cavity 11, preventing displacement or shaking during the screen protector application process. The inclined design achieves a snap-on positioning that is easy to insert but difficult to remove, enhancing safety and user experience. It also ensures the phone remains in the correct position during screen protector application, preventing uneven application or air bubbles caused by shaking.

[0068] In one specific embodiment, the dust-free chamber has a through hole 16 communicating with the inner cavity 11. The through hole 16 is used to push the mobile phone away from the inner cavity 11 after the screen protector is applied.

[0069] Specifically, a through hole 16 is provided on the body of the housing 10, extending through the outer surface of the housing 10 and the bottom of the inner cavity 11 to form an operable opening 141 channel. The through hole 16 needs to be located at the corresponding position on the back of the phone placement area, ensuring that the through hole 16 is aligned with a local area on the back of the phone, so that the user can push the phone outward and improve the safe removal process of the phone after the screen protector is applied.

[0070] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
