Description

Technical Field

[0001] This utility model relates to the field of button components, specifically to a bracket for a balance wing button. Background Technology

[0002] To achieve ultra-thin keyboards and keys with a balanced tactile feel, most technical solutions employ V-shaped balance wings (wing-type, distinct from X-shaped scissor-arm type) as the keycap. A specific example is the utility model patent CN217521888U, entitled "An Ultra-Thin Balance Key," which discloses a keycap, a base plate, and a linkage component between the keycap and the base plate. The linkage component includes a pivotally connected linkage wing and a trigger wing. Both sides of the linkage wing and the trigger wing extend pivot arms, with the ends of the pivot arms of the linkage wing and the trigger wing pivot arms pivotally connected. Each pivot arm has a limiting structure. The base plate also... A support component is provided, comprising a limiting structure to limit the movement of the linkage components; one pivot arm of the linkage wing has a central positioning post on the outer side and a pivot shaft on the inner side at its end, while the other pivot arm of the linkage wing has only a pivot hole at its end; one pivot arm of the trigger wing has a central positioning post on the outer side and a pivot shaft on the inner side at its end, while the other pivot arm of the trigger wing has only a pivot hole at its end; the linkage wing and the trigger wing are coupled to each other via their respective pivot shafts and the pivot holes of the other to form a pivotal relationship; the support component has a central positioning groove relative to the central positioning post of both the linkage wing and the trigger wing, limiting the movement of the central positioning post in three directions: left, right, and downward. This innovation is an improvement on the structure of the disclosed ultra-thin balance wing switch button.

[0003] The aforementioned ultra-thin balance wing switch button needs to achieve a certain level of rigidity and smooth wear resistance while remaining ultra-thin, which is an industry challenge. If the balance wing button's base plate (support) is made solely of plastic, it's difficult to meet the ultra-thin design requirements while maintaining sufficient strength. If only metal is used, wear is likely to occur at the contact points between the pivot arm and the support components, affecting the button's lifespan and performance stability. Furthermore, metal stamping processes are difficult to guarantee precision, hindering the refinement of product quality. Combining both methods would introduce numerous cumbersome assembly procedures, resulting in low production efficiency. Therefore, a new support structure is needed to solve these technical problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model aims to provide a support for a balance wing button that improves production efficiency, processing accuracy, and button lifespan.

[0005] To achieve this technical objective, the present invention provides a bracket for a balance wing button. The balance wing button includes a pair of plastic balance wings with their tail ends coupled together. The bracket is used to mount the balance wings. Each balance wing has limiting protrusions on both sides of its arms. The bracket includes a bracket body and four limiting frames. Each limiting frame corresponds one-to-one with the limiting protrusions. The limiting frames have limiting cavities that cooperate with the limiting protrusions to limit and position the balance wings. The bracket body is made of thin-walled metal by stamping, and the limiting frames are made of plastic. The limiting frames are directly attached to the bracket body by injection molding.

[0006] Preferably, both sides of the support body are stamped and bent with sidewalls, and the limiting frame is attached to the sidewalls of the support body.

[0007] Preferably, the side wall has a plurality of notches that enhance the injection molding bonding force at the location corresponding to the limiting frame.

[0008] Preferably, the portion of the side wall corresponding to the limiting frame has a plurality of bent feet that bend and curve upwards toward the limiting frame to enhance the injection molding bonding force.

[0009] Preferably, both bottom edges of the support body are stamped with reinforcing bends.

[0010] The beneficial effects of this utility model are as follows: The bracket of this solution is made of metal stamping to ensure rigidity in the case of ultra-thin design. The balance wing and the limiting frame on the bracket that contacts the balance wing are made of plastic injection molding, which leverages the strength advantage of metal, ensures manufacturing precision, and meets the self-lubricating and wear-resistant properties between plastics. By injection molding the limiting frame and the bracket into one piece, a large number of assembly and splicing processes are eliminated, improving the compactness of the product. Overall, this solution can significantly extend the service life of the ultra-thin balance wing button, improve manufacturing efficiency, reduce costs, and improve the quality and stability of the button.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. To provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; these embodiments are only some embodiments of the present invention; other embodiments obtained based on this application without creative effort are all within the scope of protection of the present invention.

[0018] In the following embodiments, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "top / bottom," etc., are all based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of clearly describing this embodiment. They do not indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application. At the same time, the terms "first" and "second" in the embodiments are only used for descriptive purposes and do not represent an indication or implication of relative importance.

[0019] like Figure 1-5 As shown, a specific embodiment of this utility model relates to a bracket for a balance wing 1 button. This bracket is used to mount the balance wing 1 button, which includes a pair of plastic balance wings 1 with their tail ends coupled together. Each balance wing 1 has limiting protrusions 101 on both sides of its arms. The specific implementation of this bracket will be described in detail below.

[0020] The support frame includes a support body 2 and a limiting frame 3. The support body 2 is made of thin-walled metal material and formed by stamping, ensuring that it has a certain strength and stability while meeting the requirements of ultra-thinness. The limiting frame 3 is made of plastic, and there are four limiting frames 3, each corresponding to the limiting protrusions 101 on both sides of the balance wing 1. Each limiting frame 3 has a limiting cavity 301, the shape and size of which match the limiting protrusion 101, so that when the balance wing 1 is installed, the limiting protrusion 101 can be accurately inserted into the limiting cavity 301 to achieve limiting and positioning of the balance wing 1.

[0021] The limiting frame 3 is directly formed and attached to the bracket body 2 via injection molding. During injection molding, the bracket body 2 is placed in the injection mold, and then plastic material is injected into the mold. After the plastic material cools and solidifies, the limiting frame 3 is firmly attached to the bracket body 2. This greatly enhances the bonding force between the plastic and the metal parts, preventing separation or loosening during use and improving product reliability and stability. Furthermore, injection molding integrates the plastic and metal parts into a single unit, avoiding the cumbersome process of separately processing the plastic and metal parts and then assembling them, which not only improves production efficiency but also reduces production costs.

[0022] Furthermore, due to the self-lubricating physical property of friction between plastics, when the stabilizer 1 is made of plastic, the limiting frame 3, which contacts the stabilizer 1 (plastic material) and provides positioning, is also made of plastic. This allows the friction between the two to benefit from the self-lubricating effect. Compared to friction between plastic and metal, this not only improves the smoothness of movement but also significantly enhances the product's wear resistance and extends its service life. In addition, the dimensional accuracy obtained by injection molding is higher than that obtained by metal stamping, which can also significantly improve the connection accuracy between the stabilizer 1 and the limiting frame 3, further enhancing product quality and durability.

[0023] Both sides of the support body 2 are stamped and bent with sidewalls 201, which can improve the longitudinal rigidity of the support and make it less prone to bending deformation. In addition, the limiting frame 3 is attached to the sidewalls 201 and forms an integral structure with the support body 2. Specifically, at the part of the sidewalls 201 corresponding to the limiting frame 3, one or both of the following two methods can be used to enhance the injection molding bonding force.

[0024] A plurality of notches 202 are made on the side wall 201 at the location corresponding to the limiting frame 3. The shape of the notches 202 can be rectangular, circular, etc. During the injection molding process, plastic material will fill the notches 202. After cooling and solidification, a strong locking structure is formed, which firmly locks the plastic in place, thereby increasing the bonding force between the limiting frame 3 and the side wall 201.

[0025] On the side wall 201, a plurality of bent feet 203 are bent and raised in the direction of the limiting frame 3 at the part corresponding to the limiting frame 3. The presence of bent feet 203 increases the contact area between the side wall 201 and the limiting frame 3. At the same time, during the injection molding process, the plastic material will wrap around the bent feet 203, further enhancing the bonding force between the limiting frame 3 and the bracket body 2.

[0026] To further enhance the rigidity and strength of the bracket, reinforcing bends 204 are stamped on both bottom edges of the bracket body 2. The reinforcing bends 204 can effectively increase the overall lateral strength of the bracket body 2, making it less prone to bending deformation or damage when subjected to the force generated by the balance wing 1 button, thus improving the reliability and durability of the bracket.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
