Technical Field

[0001] The present invention relates to the technical field of Bluetooth headsets, and particularly to a protective cover for a Bluetooth headset and its production process. Background Art

[0002] A Bluetooth headset applies Bluetooth technology to a hands-free headset, allowing users to be free from the annoyance of wires and easily make calls in various ways. Since the advent of Bluetooth headsets, they have always been a good tool for mobile business people to improve efficiency.

[0003] Currently, most protective covers for Bluetooth headsets are very inconvenient to use. They are not only not durable and prone to damage, but also the outer cover of the protective cover is easily lost, increasing the burden of use. Therefore, we propose a protective cover for a Bluetooth headset and its production process to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a protective cover for a Bluetooth headset and its production process, which has the advantage of preventing the outer cover from being lost, and solves the problems that most current protective covers for Bluetooth headsets are very inconvenient to use, not only not durable, prone to damage, but also the outer cover of the protective cover is easily lost, increasing the burden of use.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A protective cover for a Bluetooth headset, including a protective cover body, the protective cover body includes an upper cover and a lower cover, and the upper cover and the lower cover are adapted to each other. A connecting band is provided between the upper cover and the lower cover. A charging port is opened at the bottom of the lower cover. A buckle is provided at the top of the front surface of the lower cover. A placement groove is opened inside the lower cover. Anti-slip patterns are provided on the outer side of the protective cover body.

[0006] Preferably, a warning light hole is opened at the top of the front surface of the lower cover.

[0007] Preferably, a hanging ring is bolted to the right side of the lower cover.

[0008] Preferably, convex blocks are provided on the inner wall of the upper cover.

[0009] Preferably, a laser engraving area is opened on the lower cover.

[0010] Preferably, the upper cover, the lower cover and the connecting band are integrally formed, and the connecting band is made of TPU elastomer injection molding material.

[0011] A production process for a protective cover for a Bluetooth headset includes the following steps:

[0012] Step 1: Sheet Material: First, place the prepared product raw materials into the mold cavity for heating and melting. After that, the melted raw materials form the basic structures of the upper cover and the lower cover through extrusion and stretching. After taking out the upper cover and the lower cover, they are cooled and then punched.

[0013] Step 2: Punching the Sheet Material: Fix the lower cover on the equipment and use a punching die to punch the lower cover. Punch a charging port at the bottom position of the lower cover and a warning light hole at the rear side position of the lower cover, and then perform a forming operation.

[0014] Step 3: Sheet Material Forming: Soften three sheet materials through a heater and pressure by the equipment. During the process of the equipment closing the forming die, the sheet materials are deformed into the final desired 3D shape, completing the operation of the sheet material forming process.

[0015] Step 4: Sheet Material Blanking: Pass the formed sheet material through a blanking die by the equipment. When the blanking die is closed, the upper die punch and the lower die cavity move relative to each other to blank and separate the formed sheet material, thereby obtaining the required 3D product sheet material.

[0016] Step 5: Injection Molding: Place the formed and blanked sheet material into the injection mold for positioning, then close the mold and inject the plastic raw materials into the injection mold. After the forming part and the pouring system are closed, complete the filling until it reaches about 95% of the mold cavity. Then, cool it through the mold temperature adjustment system, and demold the formed upper cover and lower cover from the injection mold to complete the operation.

[0017] Step 6: CNC Machining Forming: Load the injection-molded product into a special fixture through CNC machining equipment for positioning, and complete the forming of the shape at the charging port through cutting with a tool.

[0018] Step 7: Laser Cutting Machining: Load the injection-molded product into a special fixture through laser cutting machining equipment for positioning. Through the high-temperature heating of the laser, the corresponding injection material is instantly vaporized to obtain the required appearance shape characteristics.

[0019] Compared with the prior art, the present invention provides a Bluetooth headset protective cover and its production process, having the following beneficial effects:

[0020] By designing a joint structure of the upper cover and the lower cover through a connecting belt, it is not only very convenient to use, strong and durable, more beautiful and practical, but also increases the automatic rebound effect when opening and closing, and can also prevent the outer cover from being lost, reducing the burden of use, solving the problem that most of the current Bluetooth headset protective covers are very inconvenient to use, not only not durable, easy to be damaged, and the outer cover of the protective cover is easy to lose, increasing the burden of use, and is worthy of promotion and use. On the other hand, the present invention adopts IMD technology to further enrich the three-dimensional sense and color expression of the product appearance, greatly improving the design space of the product appearance.
