Description
Technical Field
[0001] This utility model relates to the field of positioning base technology, and in particular discloses a mobile phone positioning base for assisting in applying a screen protector. Background Technology
[0002] In the process of applying screen protectors to smartphones, traditional auxiliary tools generally suffer from technical bottlenecks such as low positioning accuracy, poor compatibility, and easy damage to the device. Existing plastic or rigid positioning structures are prone to deformation due to insufficient material hardness, resulting in misalignment of the screen protector; fully rigid clamping designs are prone to scratching the phone frame or screen edge, especially with poor compatibility with curved screen models; single-size limiting structures cannot be compatible with the differences between multiple brands of models; in addition, traditional tools have limited functions, are difficult to interface with automated screen protector application equipment, and lack operational convenience. Utility Model Content
[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a mobile phone positioning base for assisting in applying screen protectors.
[0004] To achieve the above objectives, this utility model provides a mobile phone positioning base for assisting in screen protector application, comprising a housing, a first receiving groove formed on the housing, and a limiting member disposed within the housing; the limiting member protrudes into the first receiving groove, the first receiving groove being used to accommodate an external mobile smart terminal, and the limiting member being used to abut against the mobile smart terminal accommodated in the first receiving groove; the housing is made of a first material, the limiting member is made of a second material, and the hardness of the first material is greater than the hardness of the second material.
[0005] The inner sidewall of the first receiving groove is provided with a first limiting groove that communicates with the first receiving groove, and the limiting member is installed in the first limiting groove and protrudes into the first receiving groove.
[0006] This phone positioning holder ensures overall structural stability by using a high-hardness material (such as PC or metal) for the casing, while the limiting component uses a low-hardness material (such as silicone or TPU). This difference in material hardness achieves a dual technical effect: firstly, the rigid casing provides a precise positioning reference surface and deformation-resistant support, ensuring stable phone positioning during screen protector application; secondly, the flexible limiting component adapts to the edges of phones of different sizes through elastic deformation, and its protruding structure forms a flexible clamp, preventing scratches on the phone surface and enhancing the fixing effect through friction. In practice, the limiting component can be embedded into the casing's limiting groove via a snap-fit or interference fit. After the user places the phone into the receiving groove, the limiting component adaptively conforms to the phone's contour, forming a non-destructive fixation. It is also easy to disassemble and replace to adapt to different models, balancing versatility and protection.
[0007] The first limiting groove includes a first groove and a first notch connected to the first groove, wherein the length of the first groove is greater than the length of the first notch.
[0008] The limiting member includes a first latching block that cooperates with the first slot and a second latching block disposed on the first latching block; the second latching block protrudes from the inner surface of the first receiving slot through a first notch, and the second latching block abuts against the side wall of the external smart terminal placed on the first receiving slot.
[0009] Its first limiting groove adopts a long strip-shaped main groove combined with a notch-shaped irregular structure, so that the first locking block of the limiting component can be fully embedded in the main groove to ensure longitudinal stability. The second locking block protrudes through the notch to form a lateral limiting fulcrum. When the smart terminal is placed into the first receiving groove, the second locking block is pressed and generates a slight deformation to fit the contour of the device side wall. At the same time, the long groove design of the first groove provides a guide stroke for the locking block, so that devices of different thicknesses can obtain a stable clamping force through adaptive deformation. The length limitation of the first notch prevents the limiting component from excessive deflection.
[0010] The housing is also provided with a relief groove, which is connected to the first receiving groove. The curved contour of the relief groove is ergonomic, allowing the user's fingers to naturally insert and apply force to remove the device, avoiding hard edges that may hurt the hand or the device from slipping.
[0011] The casing is made of aluminum alloy, stainless steel, copper alloy or cast iron.
[0012] The metal material provides the casing with high rigidity, ensuring the machining precision of the first receiving groove and the clearance groove. This provides a millimeter-level positioning reference when the phone is inserted, significantly improving the efficiency of screen protector alignment. Simultaneously, the excellent heat dissipation performance of the metal casing helps the phone quickly discharge static electricity during screen protector application, preventing dust from adhering to the film. Aluminum alloy is preferred; its low density but high strength allows the casing to maintain structural rigidity while achieving a lightweight design, facilitating one-handed operation and portability. The excellent thermal conductivity of aluminum alloy quickly conducts static electricity generated during screen protector application, preventing dust particles from adhering to the film and aiding in phone heat dissipation, preventing localized overheating in the operating area. Aluminum alloy is 100% recyclable, meeting environmental requirements, and offers higher processing economics compared to materials like stainless steel, making it suitable for mass production.
[0013] The limiting component is made of soft rubber or sponge. The soft rubber limiting component adapts to different sized devices through elastic deformation. Its flexible surface can prevent the aluminum alloy shell from directly contacting the mobile phone and causing scratches, while providing cushioning protection to absorb accidental impacts.
[0014] The first receiving groove is recessed from the top surface of the housing. The housing has multiple sets of positioning holes recessed from the bottom surface, which are used to engage with positioning components on the outer shell. The cooperation between the multiple sets of positioning holes and the positioning components on the outer shell enables high-precision mechanical alignment, ensuring that the housing automatically corrects angular and positional deviations during installation, significantly improving the repeatability of positioning during film application or fixing operations. The embedded connection structure between the positioning holes and the positioning components enhances the torsional rigidity of the housing and effectively resists structural displacement caused by external impacts.
[0015] The housing is provided with a clearance hole opened from the bottom surface of the first receiving groove.
[0016] The clearance holes can precisely avoid protruding components such as mobile phone cameras, fingerprint modules, or buttons, ensuring that there is no structural interference in the functional areas when the device is placed, and guaranteeing the normal operation of shooting, unlocking, and other functions. The clearance holes can be designed to correspond to the heat dissipation areas of the device, assisting air convection to improve thermal management efficiency, or reserving installation space for external heat dissipation back clips, achieving a balance between functional expandability and structural protection.
[0017] The number of limiting members is multiple, and the multiple limiting members are arranged around the mobile smart terminal housed in the first receiving groove. The limiting members are arranged on the inner side of the first receiving groove, and there is at least one limiting member on each inner side.
[0018] The end of the second card block away from the first card block is provided with an arc-shaped contact surface, which abuts against the side wall of the external smart terminal.
[0019] The curved surface can perfectly fit the curvature of the side wall of a smartphone (especially curved screen models), and achieve stress dispersion by increasing the contact area, avoiding the screen protector peeling or the middle frame scratching caused by the concentrated pressure of traditional right-angle clips.
[0020] The second latching block has a sloping surface at its top. The sloping surface guides the phone smoothly into the positioning area through a gradient structure. The stress-dispersing design of the sloping surface can reduce fatigue damage to the soft rubber material during repeated insertion and removal, extend the service life of the limiting component, and avoid the risk of sharp edges causing bumps to the phone's frame.
[0021] The beneficial effects of this utility model are as follows: The mobile phone positioning base of this utility model achieves a dual effect by utilizing the difference in hardness between the shell and the limiting component. The hard shell provides a precise positioning reference surface and anti-deformation support, ensuring the stability of the mobile phone position during screen protector application. The soft limiting component adapts to mobile phones of different sizes through elastic deformation, forming a flexible clamping effect, avoiding scratches and enhancing the fixing effect. At the same time, the irregularly shaped first limiting groove achieves stable positioning and self-adaptive clamping, the clearance groove conforms to ergonomics for easy removal of the phone, the metal shell ensures processing accuracy, improves heat dissipation and static electricity discharge capabilities, the positioning hole improves repeatability and torsional stiffness, the clearance hole avoids structural interference and improves functional expandability, and the arc-shaped contact surface and sloped surface reduce damage to the mobile phone, effectively improving the accuracy, protection, and ease of operation of mobile phone screen protector application.
