Technical Field

[0001] This utility model relates to the field of metal products, and in particular to a metal frame structure for car remote control keys. Background Technology

[0002] A car remote key is an electronic device that communicates with the vehicle wirelessly to remotely control functions such as locking doors, starting the engine, and opening the trunk. Combining the practicality of a mechanical key with the convenience of electronic technology, it has become a standard feature in modern cars. Through technological iterations, car remote keys have evolved from a single-function system into a comprehensive system integrating security, convenience, and intelligence, greatly enhancing the user experience.

[0003] The main structure of a current car remote key includes a key frame, a key base, a key panel, and a control board. The key base and key panel are respectively fastened and fixed to the bottom and top of the key frame and together form a cavity with the key frame. The control board is located in the cavity.

[0004] In existing technologies, the key frames of car remote keys are generally made of plastic injection molding, resulting in low overall structural hardness, easy damage and deformation, poor drop resistance, easy aging, and a short service life. Furthermore, existing key frames generally lack surface treatment, resulting in an unrefined appearance and poor feel. Therefore, it is necessary to improve the key frames of current car remote keys.

[0032] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a body 10.

[0033] The body 10 is manufactured by metal injection molding. The body 10 includes a front base 11 and two side wings 12. Hanging holes 101 are formed through the upper and lower surfaces of the front base 11. The two side wings 12 extend rearward from the left and right ends of the front base 11, respectively, and are symmetrically arranged. The rear ends of the two side wings 12 are close to each other and separate to form rear openings 102. The two side wings 12 and the front base 11 together form a receiving cavity 103, which is open on both the upper and lower sides. The rear openings 102 communicate with the receiving cavity 103. In this embodiment, the body 10 is made of 316 stainless steel, meaning the metal powder used in the metal injection molding is 316 stainless steel powder. 316 stainless steel has high hardness, is not easily damaged or deformed, is corrosion-resistant, and has a high degree of refinement after polishing. Furthermore, 316 stainless steel has a wide range of surface treatment processes, including PVD, electroplating, and sandblasting.

[0034] The lower surface of the front base 11 is an inclined surface 111 that extends forward and upward, which is aesthetically pleasing. The inner edge of the upper surface of the front base 11 is recessed with a groove 104, the two ends of which extend to the inner edges of the two side wings 12, and the center of the groove 104 is recessed with a positioning hole 105 to facilitate the insertion and installation of the key panel, and to make the installation and positioning more stable.

[0035] Both outer surfaces of the two wing portions 12 are curved, and the rear opening 102 opens in a V-shape from the upper front to the lower rear, giving it a stylish and aesthetically pleasing appearance with a more technological feel. Furthermore, each of the inner surfaces of the tail ends of the two wing portions 12 has a positioning boss 121 for positioning and installing the key base. The inner surfaces of both wing portions 12 also have recessed grooves 106 near the center to allow the key panel and key base to engage with the main body 10.

[0036] Furthermore, the outer surface of the main body 10 is polished to form a polishing layer 21, and the outer surface of the polishing layer 21 is sandblasted to form a sandblasting layer 22, so as to make the product feel better, more wear-resistant, and more exquisite in appearance.

[0037] In addition, the inner wall of the accommodating cavity 103 is completely coated with an insulating coating 23 to prevent the key control board from short-circuiting with this product.

[0038] In addition, recesses 107 are provided on the outer surfaces of both wing portions 12. Each recess 107 is provided with a fluorescent coating 24. The outer surface of the fluorescent coating 24 is flush with the outer surface of the frosted layer 22. The recesses 107 can be various shapes such as circles, ovals, and triangles, and there can be multiple recesses. Multiple recesses 107 can be arranged into various patterns. Each recess 107 is embedded with a fluorescent coating 24. The fluorescent coating 24 is not easy to fall off, which makes the product fluorescent, easy to find in dark environments, and more aesthetically pleasing.

[0039] The manufacturing process of this embodiment is described in detail below:

[0040] During manufacturing, firstly, the body 10 is formed by metal injection molding. Next, the inner wall of the accommodating cavity 103 is sprayed with insulating paint to form an insulating coating 23. Then, the outer surface of the body 10 is polished to form a polishing layer 21. Next, the outer surface of the polishing layer 21 is sandblasted to form a sandblasting layer 22. Finally, fluorescent paint is filled into each recess 107 to form a fluorescent coating 24.

[0041] In use, fix the control board to the key base, then insert the control board into the accommodating cavity 103 through the lower opening of the accommodating cavity 103 and make the key base snap-fit ​​and fix it to the product. Then, snap-fit ​​and fix the key panel to the product and cover the upper opening and rear opening 102 of the accommodating cavity 103.

[0042] The key design feature of this invention is that by using metal injection molding for the main body instead of the traditional plastic structure, the overall structural hardness of the product is effectively improved, making it less prone to damage and deformation, more drop-resistant, and less prone to aging, thus extending the product's service life. At the same time, by grinding the outer surface of the main body to form a polished layer, and then sandblasting the outer surface of the polished layer to form a sandblasted layer, the overall appearance of the product is more refined, the feel is better, and it meets the needs of use.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
